[0002] [0002] Aspects of the present disclosure relate generally to wireless communication, and more particularly to techniques and apparatus for activation signal design and resource allocation. background
[0003] [0003] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging and broadcasting. Typical wireless communication systems may employ multiple access technologies that are capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmission power, and/or the like, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, division multiple access systems frequency division (OFDMA), single carrier frequency division multiple access (SC-FDMA) systems, code division time division multiple access (TD-SCDMA) and Long Term Evolution (LTE) systems . LTE/LTE Advanced is a suite of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Relationship Project (3 GPP).
[0004] [0004] A wireless communication network may include multiple base stations (BSs) that can support communication with multiple user equipment (UEs). A UE can communicate with a base station (BS) over the downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail in this document, a BS may be called a Node B, a gNB, an access point (AP), a radio head, a receive and transmit point (TRP), a 5G BS, a 5G Node B and the like.
[0005] [0005] Multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables wireless communication devices to communicate at a municipal, national, regional and even global level. 5G, which can also be called Rádio Novo (NR), is a set of improvements to the LTE mobile standard enacted by the Third Generation Relationship Project (3GPP). 5G is designed to support better mobile broadband Internet access by improving spectral efficiency, by reducing costs, by improving services, by using new spectrum, and by better integrating with other open standards using orthogonal frequency division (OFDMA) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL) using CP-OFDM and/or SC-FDM (e.g. also known as spread-transform OFDM Fourier (DFT-s-OFDM) on the uplink (UL) as well as to support beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As mobile broadband continues to increase, there is a need for improvements in 5G and LTE technologies. Preferably, these improvements should be applicable to other multiple access technologies and other telecommunication standards that employ this s technologies.
[0006] [0006] A BS may transmit a signal to a UE to indicate whether the UE should encode a subsequent communication (e.g. a downlink channel). This can improve the UE's battery efficiency due to the UE not being able to monitor subsequent communication unless the UE receives the signal. For example, such a signal can be called an activation signal. In some cases, an activation signal may apply to multiple UEs. For example, when assigning UEs to two or more UE groups, all UEs in a UE group can be activated using a single activation signal. This may be more efficient than transmitting an activation signal to a single UE, and may be more efficient than activating all UEs (instead of just a group of UEs) for subsequent communication. It may be beneficial to achieve diversity (eg, frequency diversity, time diversity, and/or spatial diversity) for activation signals that are destined for groups of different UEs. SUMMARY
[0007] [0007] Some techniques and apparatus described in the present document provide resource allocation to achieve frequency diversity, time diversity and/or spatial diversity for activation signals destined for two or more UE groups when transmitting the activation signals according to the respective resource patterns associated with the two or more groups of UEs. For example, a UE associated with a particular UE group may identify an activation signal for the particular UE group based at least in part on which resource pattern is used or for the particular UE group based at least in part in a preamble of the activation signal and/or the like. Additionally, some techniques and apparatus described in the present document provide resource allocation to achieve spatial diversity for activation signals for a single group of UEs by transmitting the activation signals using two or more antenna ports according to the respective standards. resource associated with the two or more antenna ports. In this way, group activation signaling of UEs is providing the use of the respective resource patterns, which improves diversity and allows activation signaling for groups of UEs, thereby conserving network resources that would otherwise be mode, used to signal the activation of multiple individual UEs.
[0008] [0008] Additionally, some techniques and devices described provide configurations for activation signals in this document. For example, some techniques and apparatus described herein provide for the transmission of activation signals after a configured delay which may be based at least in part on the capabilities of the UE. As another example, some techniques and apparatus described in the present document provide resource allocation for an activation signal belonging to a repetitive communication so that those UEs, which cannot decode the repetitive communications, are not activated. In this way, the configuration of wake-up signals is improved, the efficiency of UEs and groups of UEs is improved with respect to wake-up signaling, and wake-up signaling diversity is improved.

[0045] [0045] The detailed description presented below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent configurations in which the concepts described herein may be practised. The detailed description includes specific details for the purpose of providing a complete understanding of various concepts. However, it will be apparent to those skilled in the art that these concepts can be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts.
[0046] [0046] Various aspects of telecommunication systems will be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components,
[0047] [0047] By way of example, an element or any portion of an element or any combination of elements may be implemented with a "processing system" that includes one or more processors. Examples of processors include microprocessors, microcontrollers, digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware. configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system can run software. Software shall be interpreted broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, executable objectives , threads, procedures, functions and/or the like, whether called software, firmware, middleware, microcode, hardware description description language or otherwise.
[0048] [0048] Consequently, in one or more exemplary embodiments, the described functions may be implemented in hardware, software, firmware or any combination thereof. If implemented in software, functions can be stored or encoded as one or more instructions or codes on a computer-readable medium. Computer readable media include computer storage media. Non-transient storage media can be any available media that can be accessed by a general-purpose or special-purpose computer. By way of example, and without limitation, such computer readable media may comprise random access memory (RAM), read-only memory (ROM), electrically erasable programmable ROM (EEPROM), compact disc ROM (CD-ROM). ROM) or other optical disk storage, magnetic disk storage or other magnetic storage devices, combinations of the aforementioned types of computer-readable media, or any other media that can be used to store computer-executable code in the form of instructions or structures data that can be accessed by a computer.
[0049] [0049] It should be noted that while aspects can be described using terminology commonly associated with 3G and/or 4G wireless technologies, aspects of the present disclosure can be applied to other generation-based communication systems such as 5G and later, including 5G technologies.
[0050] [0050] Figure 1 is a diagram illustrating a network 100 in which aspects of the present disclosure may be practiced. Network 100 can be an LTE network or some other wireless network such as 5G network. Wireless network 100 may include multiple BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with user equipment (UEs) and may also be called a base station, BS of NR, Node B, gNB, 5G NB, access point, receive and transmit point (TRP) and /or similar. Each BS can provide communication coverage for a particular geographic area. In 3GPP, the term "cell" can refer to a coverage area of a BS and/or a BS subsystem that serves that coverage area, depending on the context in which the term is used.
[0051] [0051] A BS can provide communication coverage for a macrocell, picocell, femtocell, and/or another cell type. A macrocell can cover a relatively wide geographic area (eg, many kilometers in radius) and can allow unrestricted access by UEs with a service subscription. A picocell can cover a small geographic area and can allow unrestricted access by UEs with a service subscription. A femtocell covers a relatively small geographic area (eg, a household) and may allow restricted access by UEs that join the femtocell (eg, UEs in a closed subscriber group (CSG)). A BS for a macrocell can be called a BS macro. A BS for a femtocell may be called a femtocell or domestic BS. A BS for a femtocell may be called a femtocell or domestic BS. In the example shown in Figure 1, a BS 110a can be a BS macro for a macrocell 102a, a BS
[0052] [0052] In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile BS. In some examples, BSs may be interconnected with each other and/or with one or more other BSs or network nodes (not shown) on wireless network 100 through various types of backhaul interfaces, such as a direct physical connection, a virtual or similar with the use of any transport network
[0053] [0053] Wireless network 100 may also include relay stations. A relay station is an entity that can receive a data transmission from an upstream station (e.g. a BS or a UE) and sends a data transmission to a downstream station (e.g. a UE or a BS). A relay station can also be a UE that can relay transmissions to other UEs. In the example shown in Figure 1, a relay station 110r may communicate with a macro BS 110a and a UE 120d in order to facilitate communication between the BS 110a and the UE 120d. A relay station may be called a relay BS, relay base station, a relay and/or the like.
[0054] [0054] Wireless network 100 may be a heterogeneous network that includes BSs of different types, for example, macro BSs, pico BSs, femto BSs, relay BSs and/or the like. These different types of BSs can have different transmit power levels, different coverage areas, and different impact on interference on the wireless network 100. For example, macro BSs can have a high transmit power level (for example, 5 to 40 Watts) while pico BSs, femto BSs and relay BSs may have lower transmit power levels (eg 0.1 to 2 Watts).
[0055] [0055] A network controller 130 can couple to a set of BSs and can provide coordination and control for those BSs. The network controller 130 may communicate with the BSs via a loopback. The BSs can also communicate with each other, for example, directly or indirectly via a wireless or wired loopback.
[0056] [0056] The UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless communication network 100, and each UE may be stationary or mobile. A UE may also be called an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE can be a cell phone (e.g. a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone , a wireless local circuit (WLL) station, a tablet-type computer, a camera, a gaming device, a netbook-type computer, a smartbook-type computer, an ultrabook-type computer, medical device or equipment, sensors /biometric devices, wearable devices
[0057] [0057] Some UEs can be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices such as sensors, meters, monitors, location indicators, etc. ) or with some other entity. A wireless node can, for example, provide connectivity to or to a network (for example, a wide area network such as the Internet or a cellular network) over a wired or wireless communication link. Some UEs can be considered Internet of Things (IoT) devices, and/or can be implemented as NB-IoT (narrowband internet of things) devices. Some UEs can be considered a Customer Premises Equipment (CPE). A UE 120, such as an NB-IoT or eMTC UE 120, may remain in an idle or idle state until a wake-up signal is received. The wake-up signal may indicate that a communication is scheduled for the UE 120. In some aspects, described elsewhere in this document, the UEs 120 can be grouped into groups of UEs, which increases the efficiency of using the wake-up signal. .
[0058] [0058] In general, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a particular RAT and can operate on one or more frequencies. A RAT can be called radio technology, air interface and/or similar. A frequency may also be called a carrier, frequency channel and/or the like. Each frequency can support a single RAT in a given geographic area in order to avoid interference between the wireless networks of different RATs. In some cases, 5G RAT network can be deployed.
[0059] [0059] In some examples, access to the air interface may be programmed, where a programming entity (e.g., the base station) allocates resources for communication among some or all of the devices and equipment contained in its area or cell of the programming entity. In the present disclosure, as discussed below, the scheduling entity may be responsible for scheduling, assigning, reconfiguring and releasing resources for one or more subordinate entities. That is, for scheduled communication, subordinate entities use resources allocated by the scheduling entity.
[0060] [0060] Base stations are not the only entities that can function as a programming entity. That is, in some examples, a UE may function as a programming entity, programming resources to one or more subordinate entities (eg, one or more other UEs). In this example, the UE is functioning as a programming entity, and other UEs use resources programmed by the UE for wireless communication. A UE can function as a scheduling entity in a peer-to-peer (P2P) network and/or a mesh network. In an example mesh network, the UEs can optionally communicate directly with each other in addition to communicating with the programming entity.
[0061] [0061] Thus, in a wireless communication network with a scheduled access to frequency and time resources and which has a cellular configuration, a P2P configuration and a mesh configuration, a schedule entity and one or more subordinate entities can communicate using programmed resources.
[0062] [0062] As indicated above, Figure 1 is provided merely as an example. Other examples are possible and may differ from the example described in relation to Figure 1.
[0063] [0063] Figure 2 shows a block diagram 200 of a design of BS 110 and UE 120, which may be one of the base stations and one of the UEs in Figure 1. The BS 110 may be equipped with T antennas 234a to 234t , and the UE 120 can be equipped with antennas R 252a to 252r, where, in general, T > 1 and R > 1.
[0064] [0064] In the BS 110, a transmission processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and encoding schemes (MCSs) for each UE based on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based on the MCS (or MCSs) selected for the UE, and provide data symbols to all UEs.
[0065] [0065] At the UE 120, antennas 252a to 252r can receive the downlink signals from BS 110 and/or other base stations and can provide received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator 254 may further process input samples (e.g., for OFDM and/or the like) to obtain received symbols. A MIMO detector 256 can obtain symbols received from all demodulators R 254a to 254r, perform MIMO detection on received symbols if applicable, and provide detected symbols. A receiving processor (RX) 258 may process (e.g., demodulate and decode) the sensed symbols, provide data to the UE 120 to a data collector 260, and provide decoded control information and system information to a controller/processor. 280. A channel processor may determine the received reference signal power (RSRP), received signal strength indicator (RSSI), received reference signal quality (RSRQ), channel quality indicator (CQI), and/or similar. In some aspects, the channel processor may determine a reference value based at least in part on an activation signal, as described elsewhere in this document.
[0066] [0066] On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g. for reports comprising RSRP, RSSI, RSRQ, CQI and/or the like ) of controller/processor 280. Transmission processor 264 may also generate reference symbols for one or more reference signals. Transmission processor 264 symbols may be pre-encoded by TX MIMO processor 266 if applicable, further processed by modulators 254a to 254r (e.g. for DFT-s-OFDM, CP-OFDM and/or the like), and transmitted to BS 110. At BS 110, uplink signals from UE 120 and other UEs may be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide decoded data for a data sync 239 and decoded control information to controller/processor 240. BS 110 may include the communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include the communication unit 294, the controller/processor 290 and memory 292.
[0067] [0067] Controller/processor 240 of BS 110, controller/processor 280 of UE 120 and/or any other component (or other components) of Figure 2 can perform signaling related to activation signal resource allocation. For example, controller/processor 240 of BS 110, controller/processor 280 of UE 120, and/or any other component (or other components) of Figure 2 can perform or direct operations, for example, of method 500 of Figure 5, method 600 of Figure 6, method 1200 of Figure 12, method 1300 of Figure 13 and/or other methods as described herein. Memories 242 and 282 can store data and program codes for the BS 110 and UE 120 respectively. A scheduler 246 may schedule UEs for downlink and/or uplink data transmissions.
[0068] [0068] As indicated above, Figure 2 is provided merely as an example. Other examples are possible and may differ from the example described in relation to Figure 2. UES GROUP ENABLE SIGNAL RESOURCE ALLOCATIONS
[0069] [0069] Figures 3A to 3C are diagrams illustrating 300 examples of TDM antenna port patterns and/or antenna port patterns for activating signal transmission. In Figures 3A to 3C, two groups of UEs are described, and each group of UEs is associated with a respective resource pattern. Resources belonging to a first resource pattern are shown as WUS1 (signifying activation signal 1), and resources belonging to a second resource pattern are shown as WUS 2 (signifying activation signal 2). In some respects, a resource pattern may correspond to a single group of UEs. Additionally or alternatively, a feature pattern may correspond to an antenna port for transmitting activation signals as described in more detail below. Additionally, in Figures 3A to 3C, subframe (SF) 0 is used for a physical broadcast channel, SF 4 is used for a system information block (e.g., SIB 1), SF 5 is used for a broadcast signal. primary sync (NPSS), and SF 9 is used for a secondary sync signal (NSSS), although other configurations are possible. In some respects, activation signal resources can be associated with a plurality of resource patterns (for example, three resource patterns, five resource patterns, or any number of resource patterns).
[0070] [0070] As shown by reference number 305-1, Figure 3A shows a first example of a TDM standard and/or an antenna port broadcast feature standard. In the first example, the features of the first feature pattern alternate with features of the second feature pattern. For example, WUS 1 can be transmitted in subframes (SFs) 1, 3 and 7, while WUS 2 can be transmitted in subframes 2, 6 and 8. In this way, the time diversity of activation signals for the first group of UEs and for the second group of UEs is reached. In some respects, WUS 1 and/or WUS 2 can be transmitted using the same antenna port as the NPSS, the NSSS and/or a reference signal (e.g. an NRS and/or similar) (e.g. , in at least a single subframe), which reduces the delay associated with retuning a UE 120 receiver.
[0071] [0071] Additionally or alternatively, WUS1 can be transmitted using a first antenna port of BS 110, and WUS 2 can be transmitted using a second antenna port of BS 110. In such a case, WUS 1 and WUS 2 can be associated with the same group of UEs, and the designation of resources as WUS 1 or WUS 2 can indicate which antenna port should be used to transmit the wake-up signal on the corresponding resources. Thus, the spatial diversity of activation signals for the first group of UEs and for the second group of UEs is achieved.
[0072] [0072] As shown in Figure 3B, a second feature pattern 305-2 can transmit WUS 1 during subframes 1, 2 and 3, and can transmit WUS 2 during subframes 6, 7 and 8. This can give a higher number of simultaneous repetitions of the activation signal, which can increase a probability of successful repetition of the activation signal for UEs 120 that require multiple repetitions of the activation signal. Additionally or alternatively, the BS 110 can transmit WUS 1 using a first antenna port in subframes 1, 2 and 3, and can transmit WUS 2 using a second antenna port in subframes 6, 7 and 8. In such a case, WUS1 and WUS 2 can be associated with the same group of UEs.
[0073] [0073] As shown in Figure 3C, a third feature pattern 305-3 may transmit WUS 1 in a first frame 310 (e.g., subframes 1, 2, 3, 6, 7, and 8 of the first frame 310), and may transmit WUS 2 in a second frame 315 (e.g., subframes 1, 2, 3, 6, 7, and 8 of second frame 315). For example, the first frame 310 and the second frame 315 may be consecutive frames. This can further increase a probability of receiving the activation signal for UEs that use multiple repeats.
[0074] [0074] In some respects, multiple activation signals of a feature pattern may be configurable. For example, the BS 110 can specify any number of wake signals to be included in the WUS 1 and/or WUS 2 resource standards. In this way, wake signal versatility is enhanced, and resources can be allocated more efficiently. .
[0075] [0075] In some respects, for a single wake-up signal (eg a single WUS1 or a single WUS 2), two or more different antenna ports may be used in a single subframe. For example, a first set of symbols of the single activation signal may be transmitted from a first antenna port, and a second subset of symbols of the single activation signal may be transmitted from a second antenna port, enhancing, thus, spatial diversity.
[0076] [0076] In some respects, a UE 120 may scan or monitor wake-up signals. "Sweep" is used interchangeably with "monitor" in this document. UE 120 may identify or receive an activation signal based at least in part on a preamble of the activation signal. For example, the BS 110 may encode the preamble to identify at least a portion of a cell identifier of a camp cell or service cell associated with the UE 120. Additionally, the BS 110 may encode the preamble to identify at least a portion of a UE group identifier that identifies a group of UEs of the UE 120. In some aspects, the UE 120 may determine that an activation signal is relevant to the UE 120 when the cell identifier and the UE group identifier match respectively to a cell identifier and a UE group identifier of the UE 120. In some aspects, the UE 120 may determine that an activation signal is relevant to the UE 120 when the cell identifier corresponds to a cell identifier of the UE 120. UE 120. In some aspects, the UE 120 may determine that an activation signal is relevant to the UE 120 when the UE group identifier matches a UE group identifier of the UE 120.
[0077] [0077] In some aspects, the BS 110 may select a resource for transmitting a wake-up signal based at least in part on a UE group identifier and/or a narrow paging bandwidth of a UE 120. For example , the BS 110 can determine the resource using equations 1 to 4 below: Equation 1: SFN mod T= (T div N)*(UE_ID mod N) Equation 2: is = floor(UE_ID/N) mod Ns Equation 3: GNP = floor(UE_ID/(N*Ns)) mod Nn Equation 4: UE_Group_ID = floor(UE_ID/(N*Ns* Nn)) mod N_WUS_Groups
[0078] [0078] Equation 1 is used to identify a paging frame (e.g. paging frame number (SFN) mod T) for UE 120, where T refers to a discontinuous repeating cycle (DRX), N is a minimum value of T and an nB value configured in SIB2, and the UE ID is a UE identifier of the UE 120. Equation 2 identifies a paging occasion (PO) of the UE 120 based at least in part on the ID of EU, N and Ns. Ns is a maximum value of 1 and nB.
[0079] [0079] Equation 3 identifies a paging narrowband (PNB) of the UE 120 based at least in part on the UE_ID, N, Ns, and Nn, where Nn identifies several available narrowbands. Equation 4 identifies a UE group identifier (UE Group ID) of the UE 120 based at least in part on narrow paging bandwidth, where N_WUS_Groups identifies a total number of UE groups. In this way, the BS 110 and/or UE 120 can determine a group of UEs of the UE 120 based at least in part on a narrow paging band of the UE 120.
[0080] [0080] In some aspects, the BS 110 may provide information to a UE 120 that indicates parameters of a preamble, and the UE 120 may identify or receive a relevant wake-up signal based at least in part on the parameters. In such a case, the configuration of the UE 120 may be transparent. For example, UE 120 may not know the UE group identifier and/or particular cell identifier included in the preamble, and may search for any preamble that matches the parameters.
[0081] [0081] As indicated above, Figures 3A to 3C are provided as examples. Other examples are possible and may differ from the example described in connection with Figures 3A to 3C.
[0082] [0082] Figure 4 is a diagram illustrating an example 400 of FDM patterns for activation signal transmission. In some aspects, such as Machine-Type Communications (eMTC) radio access technology, FDM can be used. For example, and as shown in Figure 4, a resource pool 405, 410, 415, 420 for eMTC communication may include six physical resource blocks (PRBs) that are parallel in frequency. For example, the six PRBs can be associated with a single subframe or frame.
[0083] [0083] As shown by reference number 405, in some respects the features of the feature pattern shown by WUS 1 can alternate with the features of the feature pattern shown by WUS 2. This can improve frequency diversity of activation signals.
[0084] [0084] As shown by reference number 410, in some respects, multiple resources of the resource pattern shown by WUS 1 can be allocated continuously in frequency, and multiple resources of the resource pattern shown by WUS 2 can be allocated continuously in frequency. In this way, UEs that use multiple repeats can be able to decode the activation signal.
[0085] [0085] As shown by reference numbers 415 and 420, in some respects, a full bandwidth of a first frame or subframe may be allocated to WUS 1, and a complete bandwidth of a second frame or subframe may be allocated for WUS 2. In this way, a probability of decoding the activation signal for UEs that require multiple repetitions can be improved.
[0086] [0086] In some respects, resources can be allocated to activation signals using a frequency hopping technique. For example, the BS 110 may configure, for a UE 120, an initial subframe index, a frequency shift, and/or a hop-to-frequency hop time. The BS 110 can allocate resources for transmitting the trigger signal according to the initial subframe index, frequency offset and/or hop time.
[0087] [0087] As indicated above, Figure 4 is provided as an example. Other examples are possible and may differ from the example described in relation to Figure 4.
[0088] [0088] Figure 5 is a flowchart of a wireless communication method 500. The method may be performed by a base station (e.g., the BS 110 of Figure 1, the apparatus 702/702' and/or the like).
[0089] [0089] At 510, the base station can (e.g., using controller/processor 240, broadcast processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like) generate an enable signal for a communication to a UE. For example, the activation signal may include a preamble that identifies a group of UEs of the UE and/or a cell identifier of a cell of the UE. The base station may provide the wake-up signal to cause the UE to wake up or exit an idle or idle mode to receive communication.
[0090] [0090] At 520, the base station (e.g., using controller/processor 240, broadcast processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like) can transmit the activation signal using a feature selected from one or more first features of a first feature pattern or one or more second features of a second feature pattern. For example, the first resource pattern can be associated with a first group of UEs, and the second resource pattern can be associated with a second group of UEs. The base station may select the resource from the one or more first resources or the one or more second resources based at least in part on whether the wake-up signal is to be transmitted to the first group of UEs or the second group of UEs.
[0091] [0091] In some respects, the first one or more features alternate with the second one or more features in a time domain. In some respects, the first one or more features are in a first set of subframes and the one or more second features are in a second set of subframes. In some aspects, the first feature pattern is associated with a first antenna port and the second feature pattern is associated with a second antenna port. In some aspects, the activation signal is transmitted using the same antenna port as a synchronization signal or reference signal to the UE. In some aspects, the activation signal is transmitted using an antenna port other than a synchronization signal or reference signal to the UE.
[0092] [0092] In some respects, the wake-up signal is transmitted using two or more antenna ports in a single subframe. In some aspects, the wake-up signal is transmitted using the same antenna port in at least a single subframe. In some respects, multiple one or more first features or multiple one or more second features are configurable or predefined. In some respects, the first one or more resources and the second one or more resources comprise physical resource blocks (PRBs). In some respects, the first one or more features alternate with the second one or more features in a frequency domain. In some respects, the features of one or more first features or one or more second features vary in a time domain and in a frequency domain.
[0093] [0093] In some aspects, a preamble of the activation signal identifies a group of UEs from the first group of UEs and the second group of UEs to which the activation signal is associated. In some aspects, an activation signal preamble identifies a cell with which the UE is associated.
[0094] [0094] In some respects, configuration information that identifies the first UE group and the second UE group is provided in system information. In some aspects, an activation signal transmit power is configured based at least in part on a power offset relative to a downlink reference signal transmitted by the base station. In some respects, a group of UEs from the first group of UEs and the second group of UEs is assigned to the UE based at least in part on a narrow paging bandwidth of the UE.
[0095] [0095] In some aspects, the wake-up signal is further identified based at least in part on a parameter of a preamble of the wake-up signal, where the UE is configured to detect the preamble parameter.
[0096] [0096] At 530, the base station (e.g., using controller/processor 240, broadcast processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like) can transmit a communication to a UE based at least in part on the activation signal. For example, the communication may include a downlink channel. The base station may transmit the communication to the UE after transmitting the wake-up signal to the UE so that the UE monitors the communication (e.g. wakes up from idle mode and/or the like).
[0097] [0097] Although Figure 5 shows exemplary blocks of a wireless communication method, in some respects the method may include additional blocks, fewer blocks, different blocks or differently arranged blocks than those blocks shown in Figure 5. Additionally or alternatively, two or more blocks shown in Figure 5 can be performed in parallel.
[0098] [0098] Figure 6 is a flowchart of a wireless communication method 600. The method may be performed by a UE (e.g. UE 120 of Figure 1, apparatus 902/902' and/or the like).
[0099] [0099] At 610, the UE (e.g. using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor 280 and/or the like) can monitor a particular resource of a resource pattern for activation signaling associated with a group of UEs that includes the UE. For example, the resource pattern can be associated with the UEs group. The UE may monitor the particular resource for activation signaling directed at the group of UEs. When the UEs of the UE group receive an activation signal, the UEs of the UE group can perform an activation and/or receive a subsequent communication. As used herein, activating or performing an activation may refer to monitoring or initiating paging monitoring on paging occasions. For example, when activating or performing an activation, the UE can monitor or initiate monitoring of a control channel (e.g. a PDCCH such as an MTC PDCCH or a narrowband PDCCH, etc.), of a data channel (eg a PDSCH such as an MTC PDSCH or a narrowband PDSCH, etc.) and/or a different paging type. In some aspects, configuration information indicating that the UE is associated with the UE group is received by the UE in system information.
[0100] [0100] In some respects, the group of UEs is assigned to the UE based at least in part on the UE's narrow paging bandwidth. In some aspects, a particular resource length is based at least in part on a maximum number of repetitions associated with a communication to be received by the UE.
[0101] [0101] At 620, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor 280, and/or the like) can receive an activation, wherein the activation signal corresponds to at least one of a cell identifier or a UE group identifier associated with the UE. For example, at least a portion of the cell identifier and/or at least a portion of a UE group identifier may be indicated by the activation signal (e.g., a preamble of the activation signal). The UE may receive the wake-up signal based at least in part on the preamble. In some aspects, the UE group identifier portion is indicated by an activation signal preamble. In some aspects, the wake-up signal is additionally received based at least in part on a parameter of a preamble of the wake-up signal, wherein the UE is configured to detect the preamble parameter.
[0102] [0102] At 630, the UE (e.g. using controller/processor 280 and/or the like) may optionally determine a reference value based at least in part on a transmit power of the activation signal. For example, transmit power may be based at least in part on a power offset relative to a downlink reference signal received by the UE. In this way, the UE can conserve network resources that would otherwise be used for transmitting and/or use a separate sync signal to determine the reference value.
[0103] [0103] At 640, the UE (e.g. using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor 280 and/or the like) can optionally perform an activation to receive a communication based at least in part on receiving the wake-up signal. For example, the UE may wake up to receive paging at a particular time based at least in part on receiving the wake-up signal. In some aspects, the UE may remain active for a particular length of time after receiving the activation signal as described in more detail elsewhere in this document.
[0104] [0104] At 650, the UE (e.g. using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor 280 and/or the like) can optionally receive communication . For example, the UE can receive the communication after performing activation. In some respects, communication is received after a delay, where the delay is based at least in part on a UE capability.
[0105] [0105] Although Figure 6 shows exemplary blocks of a wireless communication method, in some respects the method may include additional blocks, fewer blocks, different blocks or differently arranged blocks than those blocks shown in Figure 6. Additionally or alternatively, two or more blocks shown in Figure 6 can be performed in parallel.
[0106] [0106] Figure 7 is a conceptual data flow diagram 700 illustrating the data flow between different modules/means/components in an exemplary apparatus 702. The apparatus 702 may be a base station, such as an eNB, a gNB and/or similar. In some aspects, the apparatus 702 includes a receive module 704 and a transmit module 706.
[0107] [0107] Receive module 704 may receive signals 708 from a UE 750 (e.g., UE 120 and/or the like). In some aspects, signals 708 may identify a capability of UE 750. Receive module may provide data 710 to transmit module 706. Data 710 may identify capability.
[0108] [0108] Transmission module 706 may transmit an activation signal and/or communication based at least in part on the activation signal. For example, transmission module 706 may generate a signal 712, and apparatus 702 may transmit signal 712 to UE 750. Signal 712 may include activation signal, communication, and/or other information.
[0109] [0109] The apparatus may include additional modules that perform each of the blocks of the algorithm in the aforementioned flowchart of Figure 5. As such, each block in the aforementioned flowchart of Figure 5 may be performed by a module and the apparatus may include one or more of these modules. Modules may be one or more hardware components specifically configured to execute the presented processes/algorithms, implemented by a processor configured to perform the presented processes/algorithms, stored on a computer-readable medium for implementation by a processor or some combination thereof. .

In practice, there may be additional modules, fewer modules, different modules, or differently arranged modules than those modules shown in Figure 7. Additionally, two or more modules shown in Figure 7 can be implemented in a single module, or a single module shown in Figure 7. 7 can be implemented as multiple distributed modules. Additionally or alternatively, a set of modules (e.g. one or more modules) shown in Figure 7 may perform one or more functions described as being performed by another set of modules shown in Figure 7.

[0112] [0112] The 802 processing system can be implemented with a bus architecture represented, generally, by the 804 bus. The 804 bus can include any number of interconnected buses and bridges depending on the specific application of the 802 processing system and the bandwidth constraints. general design. Bus 804 links various circuits together including one or more processors and/or hardware modules represented by processor 806, modules 704, 706, and computer readable medium/memory 808. Bus 804 may also link various other circuits, such as timing sources, peripheral elements, voltage regulators and power management circuits, which are well known in the art, and therefore will not be described further.

The transceiver 810 provides a means for communicating with various other apparatus on a transmission medium. Transceiver 810 receives a signal from one or more antennas 812, extracts information from the received signal, and provides the extracted information to processing system 802, specifically, to receiving module 704. In addition, transceiver 810 receives information from the system. processing system 802, specifically, transmission module 706, and based at least in part on received information, generates a signal to be applied to one or more antennas 812.

[0127] [0127] Figure 10 is provided as an example. Other examples are possible and may differ from the example described in conjunction with Figure 10. ACTIVATION SIGNAL CONFIGURATION
[0128] [0128] Figure 11 is a diagram illustrating an example 1100 of configuring an activation signal based at least in part on a UE capability.
[0129] [0129] As shown in Figure 11 and by reference number 1110, a UE 120 can transmit or provide information that identifies a capability. For example, the UE 120 may report information that identifies whether a receiver of the UE 120 is configured to identify legacy sync signals. Additionally or alternatively, the UE 120 may report information identifying a detection and/or synchronization time from a receiver of the UE 120. Additionally or alternatively, the UE 120 may report information identifying a synchronization processing time between the activation signal and a subsequent communication. For example, the UE 120 may report information that indicates whether the UE 120 has a first delay (for example, no delay or 0 ms), a second delay (for example, a shorter delay or approximately 15 ms), or a third delay. (for example, a longer delay or approximately 500 ms). In some cases, this delay may be referred to as an interval in this document. In some aspects, the capability may identify a repeat configuration of the UE 120 (e.g., multiple repeats needed to decode a communication). In some aspects, the capability may indicate whether the UE 120 is associated with a DRX cycle, an eDRX cycle, and/or the like.
[0130] [0130] As shown by reference number 1120, the BS 110 can determine a setting for an activation signal based at least in part on information identifying the capability. The configuration may identify a delay or interval between the activation signal and the communication, several repetitions for the activation signal and/or the like. In some respects, the configuration may identify a resource for the wake-up signal. For example, the BS 110 may determine various resources for the activation signal, an initial resource of the activation signal, one or more antenna ports for transmitting the activation signal, a transmit power for the activation signal and/or the like. as described in more detail below. In some aspects, the BS 110 may provide information identifying the configuration to the UE 120. The configuration may be referred to as the wake-up signal configuration in this document.
[0131] [0131] In some respects, the BS 110 may determine a delay or interval between the wake-up signal and communication based at least in part on capacity. For example, the BS 110 may transmit communication after a delay or gap based at least in part on information identifying the capability of the UE 120. In some aspects, the UE 120 may monitor the communication after the delay. Additionally or alternatively, the UE 120 may monitor the communication for a particular length of time, such as a maximum delay.
[0132] [0132] In some aspects, the configuration may be based at least in part on a repeat configuration of the UE 120. For example, a UE 120 may require a particular number of repeats to successfully decode a communication (e.g., 1 repeat , 4 reps, 16 reps, 64 reps, 2048 reps, etc.). It may not be beneficial to activate a UE 120 for a communication that has fewer retries than the particular number of retries since decoding the communication is unlikely to succeed.
[0133] [0133] Therefore, the length of wake-up signal resources can be configured based at least in part on a repeat configuration of UE 120. For example, a wake-up signal resource length can be determined based at least on part in a maximum number of communication repetitions. A wake-up signal can be transmitted in the wake-up signal resource, and various resources used for the wake-up signal can be based at least in part on an actual number of repetitions of the communication. The UE 120 may monitor particular resources for a wake-up signal based at least in part on a repeat configuration of the UE
[0134] [0134] For example, the maximum number of communication repetitions is considered to be 2048 repetitions. It is further considered that the UE 120 is configured with a derating factor of 16. The derating factor may identify a relationship between the number of repetitions of the communication and the number of repetitions of the activation signal. In this case, a maximum number of repetitions of the activation signal is an M-value of 128 repetitions (eg, 2048/16). If a communication must start at subframe N, then wake-up signal resources can start at subframes N-M, N-2M, N-3M and so on. More particularly, the wake-up signal resources for UE 120 may start at respective subframes N-M, N-2M, N-3M and N-4M. In other words, communication can be associated with four activation signal resources that start at N-M, N-2M, N-3M and N-4M.
[0135] [0135] The communication is now considered to have a real number of retries of 128 retries. In this case, and according to the reduction factor, the length of the activation signal can be 8 repetitions (eg 128/16). In some respects, the 8 repeats of the activation signal may be transmitted starting at the end of each activation signal feature (eg N-8, N-7.0, . . . , N-1). In some respects, the 8 repeats of the activation signal may be transmitted starting at the beginning of each activation feature (eg N-M, N-M+1, . . . , N-M+7). In this way, wake-up signal capabilities are configured based at least in part on a maximum number of retries and an actual number of retries of a communication.
[0136] [0136] As shown by reference numeral 1130, the UE 120 can determine whether to detect the wake-up signal based at least in part on a delay or interval. The delay or interval may be a delay between the transmission of the activation signal and the communication, and may be referred to as the configured delay or interval, required delay and/or the like herein. For example, BS 110 may provide information identifying the delay or gap and/or the like. In some aspects, the UE 120 may determine or select whether to detect a wake-up signal (e.g., it may enable or disable wake-up signal detection) based at least in part on the configured delay or interval configured by the base station 110 For example, the configured delay or interval may be different from a required delay or interval associated with the UE 120. In some respects, the UE 120 may indicate the selected behavior (e.g., whether wake-up signal detection is enabled or disabled). to the UE 120) to the base station and/or the mobility management entity (MME).
[0137] [0137] In some aspects, the UE 120 may determine whether to detect the wake-up signal based at least in part on a discontinuous repeating (DRX) configuration of the UE 120. For example, in the case of DRX, the UE 120 requires a zero non-zero interval between the end of the maximum wake-up signal duration and the associated paging occasion. The range can be used for tracking, channel estimation heating and/or the like. In the case of eDRX, the UE 120 may require a longer range than in DRX depending on the receiver architecture. If the UE 120 uses a receiver to update and/or load the image (e.g. software for paging detection) after deep sleep when a wake-up signal is detected, then a longer interval to perform image update for detection of paging, crawl time, channel estimation warm-up and/or the like. If the UE 120 uses a receiver to obtain the updated image, regardless of whether the UE 120 detects an activation signal, then the processing time could be similar to the processing time of DRX.
[0138] [0138] For XRD, the minimum interval for activation signal can be preset as 20 ms for MTC, 40 ms for NB-IoT and/or similar. For eDRX, several candidate ranges for the trigger signal may be predefined, and the UE 120 may report the minimum range required by selecting one of the candidate ranges. For example, a bit can indicate two different candidate minimum intervals, such as a short interval and a long interval. The short range can correspond to a DRX range, and the long range can correspond to the 1s range for NB-IoT or 2s range for MTC.
[0139] [0139] If base station 110 enables wake-up signals, then base station 110 can set the interval to be no less than the minimum interval for the DRX scenario. Otherwise, the UE 120 does not wait for the wake-up signal to be enabled. If base station 110 enables wake-up signals and supports eDRX, then base station 110 can configure the range based at least in part on the range reported by UE 120. However, the configured range may not be UE specific. in some ways. Therefore, the configured range may be different from the required range of some 120 UEs. For example, the configured range may be longer or shorter than the required UE range. Under this condition, the UE 120 may still detect the wake-up signal or the UE 120 may not detect the wake-up signal. The UE may select or determine whether to detect the wake-up signal or not (e.g., whether to enable or disable wake-up signal detection), and may explicitly indicate the selection or determination to base station 110 and/or to an MME. For example, the UE 120 may indicate a signaling bit to the MME, and the MME may inform the base station (or base stations) 110 in the tracking area of the UE 120. Alternatively, the UE behavior may be predefined without additional signage. Additionally or alternatively, the UE selection or determination may not be signaled to the base station 110 and/or the MME. Under such condition, the base station 110 may assume that the UE 120 will detect the wake-up signal, and may transmit the wake-up signal when there is paging to the UE.
[0140] [0140] As an example, the UE 120 may require a long range for the eDRX mode, but the base station 110 can configure a range to be less than the required long range of the UE. The UE 120 will still determine the wake-up signal detection at the configured short interval (using the receiver required shorter time, but achieving less power savings). Under these conditions, the base station 110 must transmit the wake-up signal if there is paging to that UE 120. However, the UE 120 may not detect the wake-up signal, but it can directly detect paging (for example, each DRX in a paging time window (PTW) in eDRX mode). Consequently, in this implementation, the base station 110 must not send the wake-up signal to avoid activating other UEs 120.
[0141] [0141] As another example, the UE 120 may require a short range, but the base station 110 may configure a range that is longer than the required range of the UE. UE 120 can still determine wake-up signal detection, but will have to wait a longer time for paging after wake-up signal detection. In that case, the base station 110 could transmit the wake-up signal if there is paging to that UE 120. However, the UE 120 may not detect the wake-up signal, but directly detect the paging (e.g., each DRX in the PTW in of eDRX). For a UE 120 with good coverage, the power savings gain when using the wake-up signal and the power burn during the long interval between the wake-up signal and the associated paging occasion are approximately the same as those without using the wake-up signal. an activation signal. Consequently, in this implementation, the base station 110 would not send the wake-up signal due to paging to that UE 120. By reducing wake-up signal transmissions, the base station 110 would prevent the wake-up of other UEs 120.
[0142] [0142] As shown by reference number 1140, the BS 110 can transmit the activation signal to the UE 120. For example, the BS 110 can transmit the activation signal using the configuration determined in conjunction with the reference number 1120 above. In some respects, the BS 110 can transmit the wake-up signal using particular resources. For example, the BS 110 may transmit the activation signal using a resource identified by the configuration using a resource associated with a group of UEs of UE 120 and/or the like.
[0143] [0143] As shown by reference numeral 1150, the UE 120 can identify the activation signal based at least in part on the configuration. For example, UE 120 may monitor a resource associated with the wake-up signal based at least in part on configuration. In some aspects, the UE 120 may identify the activation signal based at least in part on a preamble of the activation signal. In some aspects, the UE 120 may not attempt to monitor or identify the wake-up signal. For example, the UE 120 may determine that the UE 120 should not monitor the wake-up signal based at least in part on the delay or interval described in conjunction with reference number 1130 above, and may not monitor or identify the wake-up signal. .
[0144] [0144] In some aspects, a UE 120 may perform synchronization and/or determine a reference value based at least in part on an activation signal. For example, the BS 110 may configure a power level for the activation signal, and may provide information identifying the power level to the UE 120 (e.g., via a system information block, a resource signal (RRC) and/or similar). In some aspects, information that identifies the power level may include a power offset relative to a synchronization signal or downlink reference signal (e.g. PSS, SSS, NPSS, NSSS, reference signal (RS), NRS and/or similar). The UE 120 may perform synchronization and/or determine the reference value based at least in part on the power level of the trigger signal. In some aspects, when no power deviation is specified, the UE 120 may use a standard deviation (e.g., 0 dB and/or the like).
[0145] [0145] As shown by reference numeral 1160, the BS 110 may transmit a communication to the UE 120. For example, the BS 110 may use the delay or interval described above to transmit the communication. As shown by reference numeral 1170, UE 120 may receive or monitor communication. For example, the UE 120 may enter an active mode, may leave idle mode, may activate itself and/or the like. In this way, the BS 110 and UE 120 determine a configuration for a wake-up signal and perform communication after the wake-up signal is transmitted to the UE 120.
[0146] [0146] Figure 11 is provided as an example. Other examples are possible and may differ from the example described in conjunction with Figure 11.
[0147] [0147] Figure 12 is a flowchart of a wireless communication method 1200. The method may be carried out by a base station (eg BS 110 of Figure 1, apparatus 1402/1402' and/or the like).
[0148] [0148] At 1210, the base station (e.g. using controller/processor 240 and/or the like) can determine a setting for an activation signal associated with a UE. For example, the base station may receive information that identifies a UE capability. The base station can use the information that identifies the ability to determine the configuration for the wake-up signal. In some aspects, the configuration may identify a resource for the activation signal, a length of the activation signal, multiple repetitions associated with the activation signal, a transmit power for the activation signal, and/or the like. In some aspects, the base station may transmit configuration-identifying information to the UE. In some respects, the configuration is determined based at least in part on a UE capability. In some respects, the capability refers to at least one of a UE receiver type or processing time (e.g., a synchronization processing time, a tracking processing time, a processing time for loading or updating an image or control information for paging detection, a processing time for channel estimation warm-up, etc.). For example, different UEs can be associated with different receiver types that have different hardware architectures. As an example, a UE may use complex baseband processing to perform paging monitoring, and may have a low-power wake-up receiver (eg, that can perform correlations or can only perform correlations). The UE can wake up the baseband modem only when the wake up signal is detected by the low power wake up receiver. The receiver type may indicate whether the UE is associated with a low power receiver, an activating receptor, a low power activation and/or the like. Additionally or alternatively, the type of receiver may indicate a processor performing the monitoring (eg, a processor for paging monitoring, a processor for wake-up signal and/or the like).
[0149] [0149] In some respects, the configuration indicates that communication will be delayed based at least in part on capacity. In some respects, a delay for communication is based at least in part on information that identifies a minimum delay associated with one or more UEs including the UE.
[0150] [0150] At 1220, the base station (e.g., using controller/processor 240, broadcast processor 220, TX MIMO processor 230, MOD 232, antenna 234 and/or the like) can transmit the activation signal on a resource based at least in part on the configuration. For example, the base station may determine the resource for the wake-up signal based at least in part on the configuration. In some aspects, the base station may determine the resource based at least in part on a group of UEs associated with the UE. For example, the base station can select a resource corresponding to the group of
[0151] [0151] In some respects, the appeal is based at least in part on multiple repetitions of the communication. In some respects, the feature is based at least in part on an actual number of repetitions of the communication. In some aspects, the one or more first resources and the one or more second resources are multiplexed with resources associated with at least one other group of UEs from a plurality of groups of UEs including the first group of UEs and the second group of UEs. In some respects, the UE is configured with a maximum resource duration, and an actual resource duration for the wake-up signal is no longer than the configured maximum resource duration. In some respects, a resource start is configured based at least in part on a configured maximum resource duration, and an interval or delay before communication. In some respects, a resource start is aligned with a start point of an activation signal that is associated with a configured maximum resource duration.
[0152] [0152] At 1230, the base station (eg using controller/processor 240 and/or the like) may optionally determine a delay based at least in part on information identifying a minimum delay. For example, the base station can determine a delay or interval to be provided between the wake-up signal and the communication. In some aspects, the base station may determine the delay or gap based at least in part on information that identifies a minimum delay of one or more UEs. For example, the minimum delay can identify the shortest possible delay for the one or more UEs to successfully receive communication after the wake-up signal.
[0153] [0153] At 1240, the base station (e.g., using controller/processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like) can transmit a communication to the UE based at least in part on the wake-up signal. For example, the base station can transmit the communication after the delay or interval. In some respects, communication is transmitted before a configured delay has elapsed. In some aspects, an activation signal transmit power is configured based at least in part on a power offset related to a downlink reference signal transmitted by the base station. In some aspects, the UE 120 may receive or monitor the communication. For example, the UE 120 may enter an active mode, may leave idle mode, may activate itself and/or the like. In this way, the BS 110 and UE 120 determine a configuration for a wake-up signal and perform communication after the wake-up signal is transmitted to the UE 120.
[0154] [0154] Although Figure 12 shows exemplary blocks of a wireless communication method, in some respects the method may include additional blocks, fewer blocks, different blocks or differently arranged blocks than those blocks shown in Figure 12. Additionally or alternatively, two or more blocks shown in Figure 12 can be performed in parallel.
[0155] [0155] Figure 13 is a flowchart of a wireless communication method 1300. The method may be performed by a UE (e.g. UE 120 of Figure 1, apparatus 1602/1602' and/or the like).
[0156] [0156] At 1305, the UE (e.g., using controller/processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, and/or the like) can transmit optionally information to a base station that identifies a capability. In some aspects, the capability refers to at least one of a UE receiver type or a UE processing time (e.g., a synchronization processing time, a tracking processing time, a processing time for loading or update an image or control information for paging detection, a processing time for channel estimation warm-up, etc.). The type of receiver is described in more detail elsewhere in this document. In some respects, the capability may identify a delay or minimum interval associated with the UE (for example, a delay or minimum interval between the wake-up signal and the communication). In some respects, the UE may provide or signal information that identifies the capability. For example, the UE may transmit, provide, or signal the information that identifies the capability using radio resource control (RRC) signaling, medium access control (MAC) signaling, higher layer signaling, or another signaling type.
[0157] [0157] At 1310, the UE (e.g. using controller/processor 280, broadcast processor 264, TX MIMO processor 266, MOD
[0158] [0158] At 1315, the UE (e.g. using controller/processor 280 and/or the like) can optionally determine or select whether to monitor activation signaling. In some aspects, the UE may determine or select whether to detect or monitor the wake-up signal based at least in part on a configured delay or interval or an actual delay or interval. For example, the BS may select a delay or interval for the activation signal based at least in part on information that identifies the delay or required for the UE and/or other UEs. The BS can provide configuration information to the UE that identifies the configured delay or interval. The UE can determine whether the configured delay or interval is within the limits of the required delay or interval. When the configured delay or interval is within the limits of the required delay or interval, the UE can determine the detection of the activation signal. When the configured delay or interval is not within the limits of the required delay or interval, the UE may not determine the detection of the activation signal.
[0159] [0159] At 1320, the UE (e.g. using controller/processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252 and/or the like) can optionally provide information that indicates whether the UE should monitor the wake-up signal. For example, the UE may provide (e.g., signal, transmit) information to the BS that indicates whether the UE should monitor the wake-up signal. In some respects, the BS may determine whether to transmit the wake-up signal based at least in part on this information. For example, the BS may determine that the BS should not transmit an activation signal if a bordering number of UEs do not monitor activation signaling, if one or more UEs do not monitor activation signaling, and/or the like.
[0160] [0160] At 1325, the UE (e.g. using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor 280 and/or the like) can monitor signaling from activation on a resource based at least in part on an activation signal configuration. For example, the UE can monitor activation signaling on a resource. In some respects, the UE may identify the resource based at least in part on a wake-up signal configuration. For example, the wake-up tone setting can identify the resource. In some respects, the wake-up signal configuration may be based at least in part on capacity. In some respects, the UE may use information in the settings (eg, a random access setting, a feature pattern, etc.) to determine the feature. In some respects, the UE may be pre-configured with the resource. In some ways,
[0161] [0161] In some aspects, the resource is one of a plurality of resources monitored by the UE for activation signaling, where the plurality of resources is determined based at least in part on a maximum number of retries and an actual number of retries associated with communication. For example, the UE may determine an actual number of retries associated with the communication and a maximum number of retries associated with the communication. The UE may select a resource from the plurality of resources, and may monitor activation signaling on the selected resource as described in more detail elsewhere in this document.
[0162] [0162] At 1330, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor 280, and/or the like) can receive an activation. For example, the UE may receive the wake-up signal based at least in part on monitoring the wake-up signal. In some aspects, the UE may detect or identify the wake-up signal (e.g., based at least in part on a preamble of the wake-up signal, a UE group identifier of the UE, a cell identifier of the UE, and /or similar).
[0163] [0163] At 1335, the UE (e.g. using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor
[0164] [0164] At 1340, the UE (e.g. using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor 280 and/or the like) can optionally perform an activation to receive the communication. For example, the UE may identify the wake-up signal, and it may perform wake-up after a delay or interval to receive communication. In some respects, the UE may perform activation after the configured delay or interval. In some aspects, the UE may perform activation to receive data communication, control communication, paging and/or the like.
[0165] [0165] At 1345, the UE (e.g. using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor 280 and/or the like) can optionally monitor communication between the activation signal and a time associated with a configured delay. For example, the UE can start monitoring after receiving the activation signal, and can monitor until the end of a time associated with the configured delay.
[0166] [0166] At 1350, the UE (e.g. using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller/processor 280 and/or the like) can receive communication. For example, the UE can receive the communication after performing activation. In some respects, communication is received after a delay based at least in part on a UE capability. In some aspects, the UE may transmit information identifying the capability to a base station that transmits the communication. In some respects, communication is received before a maximum delay has elapsed.
[0167] [0167] Although Figure 13 shows exemplary blocks of a wireless communication method, in some respects the method may include additional blocks, fewer blocks, different blocks or differently arranged blocks than those blocks shown in Figure 13. Additionally or alternatively, two or more blocks shown in Figure 13 can be performed in parallel.
[0168] [0168] Figure 14 is a conceptual data flow diagram 1400 illustrating the data flow between different modules/means/components in an exemplary apparatus 1402. The apparatus 1402 may be a base station, such as an eNB, a gNB and/or similar. In some aspects, the apparatus 1402 includes a receiving module 1404, a determining module 1406, and a transmitting module 1408.
[0169] [0169] Receive module 1404 may receive signals 1410 from a UE 1450 (e.g., UE 120 and/or the like). In some aspects, signals 1410 may identify a capability of UE 1450. Receive module may provide data 1412 to determination module
[0170] [0170] Determination module 1406 may determine a setting for the activation signal based at least in part on data 1412. In some aspects, determination module 1406 may determine a delay for transmission of communication based at least in part information that identifies a minimum or required delay of one or more UEs. In some aspects, the determination module 1406 may determine a resource for the activation signal. Determination module 1406 may provide data 1414 to transmission module 1408. For example, data 1414 may indicate a resource for the activation signal, may identify the activation signal, may indicate that transmission module 1408 should generate and /or transmit the activation signal and/or the like.
[0171] [0171] Transmission module 1408 may transmit an activation signal and/or communication based at least in part on the activation signal. For example, transmission module 1406 may generate signal 1416, and apparatus 1402 may transmit signal 1416 to UE 1450. Signal 1416 may include activation signal, communication, and/or other information, such as configuration for the activation signal and/or similar.
