[0001] [0001] Aspects of the present disclosure generally refer to wireless communication and, more particularly, to techniques and apparatus for dynamic power reserve reporting on Novo Rádio. BACKGROUND
[0002] [0002] Wireless communication systems are widely installed to provide various telecommunication services such as telephony, video, data, messages and broadcasts. Typical wireless communication systems can employ multiple access technologies with the ability to support communication with multiple users by sharing available system resources (for example, bandwidth, transmission power, etc.). Examples of such multiple access technologies include code division multiple access systems (CDMA), time division multiple access systems (TDMA), frequency division multiple access systems (FDMA), division multiple access systems orthogonal frequency (OFDMA), single carrier frequency division multiple access systems (SC-FDMA), time division synchronous code division multiple access systems (TD-SCDMA) and Long Term Evolution (LTE) . LTE / LTE-Advanced is a set of enhancements to the mobile standard of the Universal Mobile Telecommunications System (UMTS) promulgated by the Third Generation Partner Project (3GPP).
[0003] [0003] A wireless communication network can include numerous base stations (BSs) that can support communication to numerous user devices (UEs). A UE can communicate with a BS through the downlink and the uplink. The downlink (or direct link) refers to the communication link from the BS to the UE, and the uplink link (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 can be referred to as a Node B, a gNB, an access point (AP), a radio head, a transmit receiving point (TRP), a BS de Novo Radio (NR), a Node B 5G and / or similar.
[0004] [0004] The multiple access technologies above have been adopted in several telecommunication standards to provide a common protocol that allows different user equipment to communicate at a municipal, national, regional and even global level. Novo Rádio (NR), which can also be referred to as 5G, is a set of enhancements to the mobile LTE standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of the new spectrum, and integrating better with other open standards using a prefix OFDM cyclic (CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and / or SC-FDM (for example, also known as discrete discrete Fourier transform ODFM (DFT-s-OFDM) ) on the uplink (UL), as well as supporting beam formation, multiple input and multiple output antenna technology (MIMO), and carrier aggregation. However, as the demand for mobile broadband access continues to increase, there is a need for further improvements in LTE and NR technologies. Preferably, these enhancements should apply to other multiple access technologies and to the telecommunication standards that employ those technologies. SUMMARY

[0036] [0036] Various aspects of the disclosure are described more fully hereinafter in this document with reference to the accompanying drawings. This disclosure can, however, be incorporated in many different ways and should not be construed as limited to any specific structure or function presented throughout this disclosure. Instead, these aspects are provided in such a way that this disclosure is meticulous and complete, and will fully extend the scope of the disclosure to those skilled in the art. Based on the teachings in this document, one skilled in the art should note that the scope of the disclosure is intended to cover any aspects of the disclosure disclosed in this document, regardless of whether they are deployed independently or combined with any other aspect of the disclosure. For example, an apparatus can be implanted or a method can be practiced using any number of aspects set out in this document. In addition, the scope of the disclosure is intended to cover such apparatus or method that is practiced using another structure, functionality or structure and functionality in addition to or in addition to the various aspects of the disclosure set out in this document. It should be understood that any aspect of the disclosure disclosed in this document may be incorporated by one or more elements of a claim. The word "exemplary" is used in this document to mean "to serve as an example, occurrence or illustration". Any aspect described in this document as "exemplary" should not necessarily be interpreted as preferential or advantageous over another aspect. Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the detailed description below and illustrated in the attached drawings through various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as “elements”). These elements can be implemented using hardware, software or combinations thereof. Whether these elements are implemented as hardware or software depends on the particular design and application restrictions imposed on the general system.
[0037] [0037] An access point (“AP”) can comprise, be deployed as, or known as, NodeB, Radio Network Controller (“RNC”), eNodeB (eNB), Base Station Controller (“BSC”) , Transceiver Base Station (“BTS”), Base Station (“BS”), Transceiver Function (“TF”), Radio Router, Radio Transceiver, Basic Service Set (“BSS”), Service Set Extended (“ESS”), Radio Base Station (“RBS”), Node B (NB), gNB, 5G NB, RN BS, Transmission Receiving Point (TRP) or some other terminology.
[0038] [0038] An access terminal ("AT") may comprise, be deployed as, or be known as, an access terminal, a subscriber station, a subscriber unit, a mobile station, a remote station, a remote terminal, a terminal user agent, user agent, user device, user equipment (UE), user station, wireless node or some other terminology.
[0039] [0039] It is noted that, although the aspects can be described in this document using terminology commonly associated with 3G and / or 4G wireless technologies, the aspects of the present disclosure can be applied in other generation-based communication systems, such as 5G and later, including NR technologies.
[0040] [0040] Figure 1 is a diagram illustrating a network 100 in which aspects of the present disclosure can be practiced. Network 100 can be an LTE network or some other wireless network, such as a 5G or NR network. Wireless network 100 may include a number of 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 the user equipment (UE) and can also be referred to as a base station, a BS of NR, a Node B, a gNB, a 5G NB, an access point, a TRP , etc. Each BS can provide communication coverage for a specific geographic area. In 3GPP, the term “cell” can refer to a BS coverage area and / or a BS subsystem that serves that coverage area, depending on the context in which the term is used.
[0041] [0041] A BS can provide communication coverage for a macrocell, a picocell, a femtocell and / or another type of cell. A macrocell can cover a relatively large geographical area (for example, several kilometers in radius) and can allow unrestricted access by UEs with a service subscription. A picocell can cover a relatively small geographical area and can allow unrestricted access by UEs with a service subscription. A femtocell can cover a relatively small geographical area (for example, a residence) and can allow unrestricted access by UEs that are associated with the femtocell (for example, UEs in a closed subscriber group (CSG)). A BS for a macrocell can be referred to as a BS macro. A BS for a picocell can be referred to as a BS peak. A BS for a femtocell can be referred to as a BS femto or a domestic BS. In the example shown in Figure 1, a BS 110a can be a macro BS for a macrocell 102a, a BS 110b can be a BS peak for a picocell 102b, and a BS 110c can be a BS femto for a femtocell 102c. A BS can support one or multiple (for example, three) cells. The terms "eNB", "base station", "BS of NR", "gNB", "TRP", "AP", "node B", "5G NB" and "cell" can be used interchangeably in this document .
[0042] [0042] In some examples, a cell may not necessarily be stationary, and the geographical area of the cell may move according to the location of a mobile BS. In some examples, BSs can be interconnected with each other and / or with one or more other BSs or network nodes (not shown) on access network 100 through various types of backhaul interfaces such as a direct physical connection, a virtual network and / or the like using any suitable transport network.
[0043] [0043] Wireless network 100 may also include relay stations. A relay station is an entity that can receive a data transmission from an upstream station (for example, a BS or a UE) and send a data transmission to a downstream station (for example, 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 110d can communicate with the macro BS 110a and a UE 120d in order to facilitate communication between BS 110a and UE 120d. A relay station can also be referred to as a relay BS, a relay base station, a relay, etc.
[0044] [0044] Wireless network 100 can be a heterogeneous network that includes BSs of different types, for example, macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs can have different levels of transmission power, different coverage areas and impact on different interference in the wireless network 100. For example, macro BSs can have a high level of transmission power (for example, 5 to 40 Watt) while peak BSs, femto BSs and retransmission BSs may have lower transmit power levels (for example, 0.1 to 2 Watt).
[0045] [0045] A network controller 130 can couple with a set of BSs and can provide coordination and control for those BSs. The network controller 130 can communicate with the BSs via a backhaul. BSs can also communicate with each other, for example, directly or indirectly via a wireless or wired backhaul.
[0046] [0046] UEs 120 (e.g. 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. A UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. An UE can be a cell phone (for example, a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a portable device, a laptop computer, a cordless phone , a local wireless loop station (WLL), a tablet computer, a camera, a gaming device, a netbook computer, a smartbook computer, an ultrabook computer, medical device or equipment, sensors / biometric devices, devices that can be worn close to the body (smart watches, smart clothing, smart glasses, smart bracelets, smart jewelry (for example, smart ring, smart bracelet)), an entertainment device (for example, a music or video, or a satellite radio), a vehicle component or sensor, smart meters / sensors, industrial manufacturing equipment, a global positioning any other suitable device that is configured to communicate with a wireless or wired medium.
[0047] [0047] In Figure 1, a continuous line with double arrows indicates desired transmissions between a UE and a serving BS, which is a BS designated to serve the UE on the downlink and / or on the uplink. A dashed line with double arrows indicates potentially transmissions of interference between a UE and a BS.
[0048] [0048] In general, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, an air interface, etc. A frequency can also be referred to as a carrier, a frequency channel, etc. Each frequency can support a single RAT in a given geographic area in order to avoid interference between wireless networks from different RATs. In some cases, NR or RAT 5G networks can be deployed.
[0049] [0049] In some examples, access to the air interface can be programmed, in which a programming entity (for example, a base station) allocates resources for communication among some or all devices and equipment within the service area or programming entity cell. In the present disclosure, as discussed below, the programming entity may be responsible for programming, assignment,
[0050] [0050] 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 for one or more subordinate entities (for example, 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 programming entity in a peer-to-peer (P2P) network and / or a mesh network. In an example of a mesh network, UEs can optionally communicate directly with each other in addition to communicating with the programming entity.
[0051] [0051] Thus, in a wireless communication network with programmed access to time-frequency resources and that has a cellular configuration, a P2P configuration and a mesh configuration, a programming entity and one or more subordinate entities can communicate using the programmed resources.
[0052] [0052] As indicated above, Figure 1 is provided as an example only. Other examples are possible and may differ from what was described in relation to Figure 1.
[0053] [0053] Figure 2 shows a block diagram of a base station 110 and UE 120 project, which can be one of the base stations and one of the UEs in Figure 1. Base station 110 can be equipped with antennas T 234a to 234t, and the UE 120 can be equipped with antennas R 252a to 252r, where, in general, T ≥ 1 and R ≥ 1.
[0054] [0054] At base station 110, a transmission processor 220 can receive data from a data source 212 to one or more UEs, select one or more modulation and encryption schemes (MCSs) for each UE based at least in part in the channel quality indicators (CQIs) received from the UE, process (for example, encode and modular) the data for each UE based at least in part on the MCS (or MCSs) selected for the UE, and provide data symbols for all UEs. Transmission processors 220 can also process system information (for example, for semi-static resource partition information (SRPI), etc.) and control information (for example, CQI requests, leases, upper layer signaling, etc.) ) and provide overload symbols and control symbols. The transmission processor 220 can also generate reference symbols for reference signals (for example, the CRS) and synchronization signals (for example, the primary synchronization signal (PSS) and secondary synchronization signal (SSS)). A transmission (TX) 230 multiple input and multiple output (MIMO) processor can perform spatial processing (for example, pre-encryption) on data symbols, control symbols, overload symbols and / or reference, if applicable, and can provide T output symbol streams for T modulators (MODs) 232a to 232t. Each modulator 232 can process a respective output symbol stream (for example, for OFDM, etc.) to obtain an output sample stream. Each 232 modulator can further process (for example, convert to analog, enlarge, filter and regulate upward) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via the T antennas 234a to 234t, respectively. According to certain aspects described in more detail below, the synchronization signals can be generated with location coding to carry additional information.
[0055] [0055] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations and can provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each 254 modulator can condition (for example, filter, enlarge, down-convert and digitize) a received signal to obtain input samples. Each modulator 254 can further process the input samples (for example, for OFDM, etc.) to obtain received symbols. A MIMO 256 detector 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 258 can process (e.g., demodulate and decode) the detected symbols, providing decoded data to the UE 120 for a 260 data warehouse, and providing decoded control and system information to a controller / processor 280. One channel processor can determine RSRP, RSSI, RSRQ, CQI, etc.
[0056] [0056] On the uplink, at UE 120, a transmission processor 264 can receive and process data from a data source 262 and control information (for example, for reports comprising RSRP, RSSI, RSRQ, CQI, etc.) controller / processor 280. The transmission processor 264 can also generate reference symbols for one or more reference signals. The transmission processor symbols 264 can be pre-encoded by a MIMO TX 266 processor, if applicable, further processed by modulators 254a to 254r (for example, for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to base station 110. At base station 110, uplink signals from UE 120 and other UEs can be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236, if applicable, and additionally processed by a receiving processor 238 to obtain decoded data and control information sent by the UE
[0057] [0057] In some respects, one or more components of the UE 120 may be included in a housing. Controllers / processors 240 and 280 and / or any other component (or components) in Figure 2 can direct operation on base station 110 and EU 120, respectively, to perform the dynamic power reserve and / or power control report. SRS on Novo Rádio, as described in more detail anywhere in this document. For example, controller / processor 280 and / or other processors and modules on UE 120, can perform or direct UE 120 operations to perform the dynamic power reserve report and / or SRS power control on Novo Rádio. For example, controller / processor 280 and / or other controllers / processors and modules in UE 120 can perform or direct operations, for example, process 800 in Figure 8, process 900 in Figure 9, process 1000 in Figure 10, process 1100 of Figure 11, process 1200 of Figure 12, process 1300 of Figure 13, and / or other processes as described in the present document. In some respects, one or more of the components shown in Figure 2 can be used to carry out example process 800, example process 900, example process 1000, example process 1100, example process 1200, example process 1300, and / or other processes for the techniques described in this document. Memories 242 and 282 can store data and program codes for base station 110 and UE 120, respectively. A programmer 246 can program UEs for data transmission on the downlink and / or uplink.
[0058] [0058] In some respects, the UE 120 may include means for determining a plurality of signals to be multiplexed by frequency division in an uplink transmission, means for determining a maximum transmission power based, at least in part, on the plurality of signals, means for transmitting the dynamic power reserve report that indicates a dynamic power reserve value determined based, at least in part, on the maximum transmission power, and / or means for carrying out other operations described in this document . Such means can include one or more components shown in Figure 2.
[0059] [0059] Additionally or alternatively, the UE 120 may include means for determining one or more signals, of a plurality of signals, to be transmitted in an uplink transmission, means for determining a maximum transmission power based, at least on partly, on one or more signals, means for transmitting a dynamic power reserve report that indicates a dynamic power reserve value determined based, at least in part, on the maximum transmission power, and / or means for carrying out other operations described in this document. Such means can include one or more components shown in Figure 2.
[0060] [0060] Additionally or alternatively, UE 120 may include means for generating a dynamic power reserve report, means for transmitting the dynamic power reserve report on an uplink control channel or as part of the link control information uplink data transmitted on an uplink data channel, and / or means to perform other operations described in this document. Such means can include one or more components shown in Figure 2.

Such means can include one or more components shown in Figure 2.
[0062] [0062] Additionally or alternatively, UE 120 may include means for determining a signal to be transmitted by means of a beam; means for determining maximum transmission power for the beam based, at least in part, on the signal; means for transmitting the signal via the beam based, at least in part, on the maximum transmission power; and / or the like. Such means can include one or more components shown in Figure 2.
[0063] [0063] As indicated above, Figure 2 is provided as an example only. Other examples are possible and may differ from what was described in relation to Figure 2.
[0064] [0064] Figure 3 shows an exemplary frame structure 300 for FDD in a telecommunications system (for example, LTE). The transmission timeline for each of the downlink and uplink links can be divided into radio frame units. Each radio frame can have a predetermined duration (for example, 10 milliseconds (ms)) and can be divided into 10 subframes with indexes from 0 to 9. Each subframe can include two intervals. Each radio frame can then include 20 intervals with indexes from 0 to
[0065] [0065] Although some techniques are described in this document in connection with frames, subframes, partitions, and / or the like, these techniques can apply equally to other types of wireless communication structures, which can be referred to using the terms in addition to "frame", "subframe", "partition", and / or similar in NR 5G. In some respects, a wireless communication structure may refer to a periodically connected communication unit defined by a wireless communication standard and / or protocol.
[0066] [0066] In certain telecommunications (for example, LTE), a BS can transmit a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) on the downlink in the center of the system bandwidth for each cell supported by the BS. The PSS and SSS can be transmitted in symbol periods 6 and 5, respectively, in subframes 0 and 5 of each radio frame with the normal cyclic prefix, as shown in Figure 3. PSS and SSS can be used by UEs for cell search and acquisition. The BS can transmit a cell-specific reference signal (CRS) through the system bandwidth for each cell supported by the BS. The CRS can be transmitted at certain symbol periods in each subframe and can be used by the UEs to perform channel estimation, channel quality measurement and / or other functions. The BS can also transmit a physical broadcast channel (PBCH) in symbol periods 0 to 3 on partition 1 of certain radio frames. The PBCH can load some system information. The BS can transmit other system information such as system information blocks (SIBs) on a physical downlink shared channel (PDSCH) in certain subframes. The BS can transmit control information / data on a physical downlink control channel (PDCCH) in the first periods of symbol B of a subframe, where B can be configurable for each subframe. The BS can transmit traffic data and / or other data in the PDSCH for the remaining symbol periods of each subframe.
[0067] [0067] In other systems (for example, such NR or 5G systems), a Node B can transmit these or other signals at these locations or at different locations in the subframe.
[0068] [0068] As indicated above, Figure 3 is provided merely as an example. Other examples are possible and may differ from what was described in relation to Figure 3.
[0069] [0069] Figure 4 shows two exemplary subframe formats 410 and 420 with the normal cyclic prefix. The available time frequency resources can be divided into resource blocks. Each resource block can cover 12 subcarriers in one partition and can include a number of resource elements. Each feature element can cover a subcarrier in a symbol period and can be used to send a modulation symbol, which can be a real or complex value.
[0070] [0070] The subframe format 410 can be used for two antennas. A CRS can be transmitted from antennas 0 and 1 in symbol periods 0, 4, 7 and 11. A reference signal is a signal that is known a priori by a transmitter and a receiver and can also be referred to as a pilot signal. A CRS is a reference signal that is specific to a cell, for example, generated based at least in part on a cell identity (ID). In Figure 4, for a given resource element without a Ra tag, a modulation symbol can be transmitted on that resource element from antenna a, and no modulation symbol can be transmitted on that resource element from other antennas. The subframe format 420 can be used with four antennas. A CRS can be transmitted from antennas 0 and 1 in symbol periods 0, 4, 7 and 11 and from antennas 2 and 3 in symbol periods 1 to 8. For both subframe formats 410 and 420, a CRS can be transmitted on evenly spaced subcarriers, which can be determined based in part on the cell ID. CRSs can be transmitted on the same or different subcarriers, depending on their cell IDs. For both subframe formats 410 and 420, resource elements not used for CRS can be used to transmit data (for example, traffic data, data control and / or other data).
[0071] [0071] The PSS, SSS, CRS and PBCH in LTE are described in 3 GPP TS 36.211, entitled “Evolved Universal Terrestrial Radio Access (E-UTRA); Physical Channels and Modulation ”, which is publicly available.
[0072] [0072] An interlacing structure can be used for each of the down link and the up link for FDD in certain telecommunications systems (for example, LTE). For example, Q interlaces with indexes from 0 to Q-1 can be defined, where Q can be equal to 4, 6, 8, 10 or some other value. Each interlacing can include subframes that are separated by Q frames. In particular, the interlacing q may include subframes q, q + Q, q + 2Q, etc., where q Є {0, ..., Q-1}.
[0073] [0073] The wireless network can support the request for hybrid automatic retransmission (HARQ) for data transmission on the downlink and on the uplink. For HARQ, a transmitter (for example, a BS 110) can send one or more transmissions from a packet until the packet is correctly decoded by a receiver (for example, a UE) or some other termination condition is met. For synchronous HARQ, all packet transmissions can be sent in single-interleaved subframes. For asynchronous HARQ, each transmission of the packet can be sent in any subframe.
[0074] [0074] A UE can be located within the coverage of multiple BSs. One of these BSs can be selected to serve the UE. The serving BS can be selected based at least in part on various criteria such as received signal strength, received signal quality, lost path, and / or the like. The quality of the received signal can be quantified by a signal to noise and interference ratio (SINR), or a reference signal received quality (RSRQ), or some other metric. The UE can operate in a dominant interference scenario where the UE can observe high interference from one or more interfering BSs.
[0075] [0075] Although the aspects of the examples described in this document may be associated with LTE technologies, aspects of the present disclosure may be applicable with other wireless communication systems, such as NR or 5G technologies.
[0076] [0076] New Radio (NR) can refer to radios configured to operate according to a new air interface (for example, in addition to air interfaces based on Orthogonal Frequency Division Multiple Access (OFDMA)) or transport layer fixed (for example, other Internet Protocol (IP)). In aspects, NR can use OFDM with a CP (in this document, referred to as OFDM with cyclic prefix or CP-OFDM) and / or SC-FDM on the uplink, can use CP-OFDM on the downlink and include for the operation of half-duplex using TDD. In terms of aspects, NR can, for example, use OFDM with a CP (in the present document, referred to as CP-OFDM) and / or multiplexing by dispersed orthogonal frequency division in discrete Fourier transform (DFT-s-OFDM) in the uplink , you can use CP-OFDM on the downlink and include support for half-duplex operation using TDD. NR may include Intensified Mobile Broadband (eMBB) service that targets broadband bandwidth
[0077] [0077] A single component carrier bandwidth of 100 MHZ can be supported. NR resource blocks can span 12 subcarriers with a 75 kilo-hertz (kHz) subcarrier bandwidth over a duration of 0.1 ms. Each radio frame can include 50 subframes with a duration of 10 ms. Consequently, each subframe can be 0.2 ms long. Each subframe can indicate a link direction (for example, DL or UL) for data transmission and the link direction for each subframe can be dynamically changed. Each subframe can include DL / UL data as well as DL / UL control data. The subframes of UL and DL for NR can be as described in more detail below in relation to Figures 7 and
[0078] [0078] The beam formation can be supported and the beam direction can be dynamically configured. Pre-encrypted MIMO transmissions can also be supported. The MIMO configurations on the DL can support up to 8 transmission antennas with multi-layered DL transmissions up to 8 streams and up to 2 streams per UE. Multilayer transmissions with up to 2 streams per EU can be supported. Multiple cell aggregation can be supported with up to 8 server cells. Alternatively, NR can support a different air interface, in addition to an OFDM based interface. NR networks can include entities such as central units or distributed units.
[0079] [0079] The RAN can include a central unit (CU) and distributed units (DUs). An NR BS (for example, gNB, Node B 5G, Node B, transmit receive point (TRP), access point (AP)) can correspond to one or multiple BSs. NR cells can be configured as access cells (ACells) or data-only cells (DCells). For example, the RAN (for example, a central unit or distributed unit) can configure the cells. DCells can be cells used for carrier aggregation or dual connectivity, but are not used for initial access, repeated cell selection / selection, or automatic switching. In some cases, DCells may not transmit synchronization signals. In some cases, DCells can transmit synchronization signals. NR BSs can transmit downlink signals to UEs that indicate the cell type. Based at least in part on the cell type indication, the UE can communicate with the BS of NR. For example, the UE can determine BSs of NR to consider cell selection, access, automatic change and / or measurement based at least in part on the indicated cell type.
[0080] [0080] As indicated above, Figure 4 is provided merely as an example. Other examples are possible and may differ from what was described in relation to Figure 4.
[0081] [0081] Several changes to communications with the use of New Access Radio (RAT) technology
[0082] [0082] Figure 5 is a diagram illustrating an example 500 of dynamic power reserve report in Novo Rádio, according to various aspects of the present disclosure.
[0083] [0083] As shown in Figure 5, an UE 505 can communicate with a base station 510 to perform the dynamic power reserve report. In some respects, UE 505 may correspond to one or more UEs described anywhere in this document, such as UE 120 of Figure 1 and / or the like. In addition or alternatively, base station 510 may correspond to one or more base stations described anywhere in the present document, such as base station 110 of Figure 1 and / or the like.
[0084] [0084] As shown by numerical reference 515, UE 505 can determine one or more signals, of a plurality of signals, to be transmitted in an uplink transmission. The one or more signals may include, for example, an uplink control channel signal (eg, a physical uplink control channel signal (PUCCH), a shortened PUCCH signal (sPUCCH) and / or the like) , an uplink data channel signal (for example, an uplink shared physical channel signal (PUSCH), a shortened PUSCH signal (sPUSCH), an ultra-reliable low-latency communication PUCCH (URLLC), a PUCCH enhanced mobile broadband (eMBB) and / or similar), an audible reference signal (SRS), another type of reference signal and / or the like. In some respects, the one or more signals include signals (for example, at least two signals, at least three signals, etc.) to be multiplexed by frequency division in the uplink transmission. For example, an uplink control channel signal and an SRS can be multiplexed by frequency division; an uplink data channel signal and an SRS can be multiplexed by frequency division; an uplink control channel signal and an uplink data channel signal can be multiplexed by frequency division; an uplink control channel signal, an uplink data channel signal, and an SRS can be multiplexed by frequency division; and / or the like.
[0085] [0085] As shown by numerical reference 520, different signals from the plurality of signals can correspond to different maximum transmission powers (for example, Pcmáx or Pemáx values). For example, a PUSCH signal can correspond to a first maximum transmission power, shown as Pcmáx A, a PUCCH signal can correspond to a second maximum transmission power, shown as Pcmáx B, an SRS can correspond to a third power of maximum transmission, shown as Pcmáx C and / or similar. These signals and corresponding maximum transmission powers are shown as examples, and other examples are possible.
[0086] [0086] As shown by numerical reference 525, the UE 505 can determine a maximum transmission power, to be used to determine a dynamic power reserve value, based, at least in part, on one or more signals and on one or more corresponding maximum transmission powers. When different signals correspond to different maximum transmission powers (for example, Pcmáx or Pemáx values), then the UE 505 can determine a specific maximum transmission power to be used to calculate the dynamic power reserve value. For example, the dynamic power reserve value can be calculated as a difference between a maximum transmission power (for example, Pcmáx or Pemáx) and a transmission power that would have been used without power restrictions (for example, which can be an unrestricted transmit power for a single signal or a sum of unrestricted transmit powers for multiple signals, such as higher priority signals).
[0087] [0087] In the event that a signal is included in the uplink transmission, then the UE 505 can use the maximum transmission power that corresponds to that one signal. However, if multiple signals are multiplexed by frequency division in the uplink transmission, then the UE 505 can determine a maximum transmission power based, at least in part, on the multiple signals. In some respects, the UE 505 can select a maximum transmission power that corresponds to the maximum priority signal to be transmitted. For example, if the plurality of signals includes a signal on the uplink control channel (e.g., the PUCCH), then the UE 505 can select the maximum transmit power that corresponds to the uplink control channel. In some aspects, the UE 505 can always use a specific maximum transmit power, associated with a specific signal (for example, an uplink control channel signal) regardless of the possibility that that signal is being transmitted. In this way, the UE 505 can conserve processing resources by simplifying the selection of the maximum transmit power value to be used to determine the dynamic power reserve value.
[0088] [0088] Additionally or alternatively, the UE 505 can determine the maximum transmission power based, at least in part, on an indication, associated with the plurality of signals, indicated on a radio resource control (RRC) message. For example, an RRC message (for example, from base station 510) can indicate which maximum transmit power to use for different combinations of multiple signals. Additionally or alternatively, the UE 505 can determine the maximum transmit power based, at least in part, on a maximum transmit power of a signal that is included in the uplink transmission. Additionally or alternatively, the UE 505 may determine the maximum transmit power based, at least in part, on multiple maximum transmit powers that correspond to multiple signals included in the uplink transmission. For example, the UE 505 can average multiple maximum transmission powers, can select a maximum of maximum transmission powers, can select a minimum of maximum and / or similar transmission powers.
[0089] [0089] In some respects, uplink transmission can be transmitted over a specific beam (for example, a specific antenna beam), and different beams can be associated with different maximum transmission powers (for example, Pcmáx or Pemáx values ). In that case, the UE 505 can determine the maximum transmission power based, at least in part, on a beam through which the uplink transmission is to be transmitted. Additionally or alternatively, the UE 505 can determine the maximum transmission power based, at least in part, on the possibility that the plurality of signals are transmitted on the same or different beams. For example, if the plurality of signals are transmitted in different beams, then the UE 505 can use a maximum transmission power that corresponds to a specific signal, such as an uplink control signal. In some respects, the UE 505 can determine the maximum transmission power based, at least in part, on the possibility that the signals that should be included in the uplink transmission are multiplexed by frequency division over the entire transmission time. uplink transmission or a partial uplink transmission time. In this way, the maximum transmission power to be used to calculate a dynamic power reserve value can be determined according to the transmission characteristics, thereby improving performance.
[0090] [0090] As shown by numerical reference 530, the UE 505 can transmit a dynamic power reserve (PHR) report that indicates a dynamic power reserve value determined based, at least in part, on the maximum transmission power. As described in more detail below in combination with Figure 6, in some respects, the UE 505 can transmit the PHR on an uplink control channel. Additionally or alternatively, the UE 505 can transmit the PHR as part of the uplink control information that is included in an uplink data channel (for example, with or without including uplink data in the uplink transmission) .
[0091] [0091] In some respects, the UE 505 may determine that it transmits the PHR on the uplink control channel based, at least in part, on a determination that the uplink control channel has a specific format. Additionally or alternatively, the UE 505 may determine that the PHR is transmitted on the uplink control channel based, at least in part, on a determination that an uplink transmission payload size satisfies a condition (for example , is less than or equal to a limit). Additionally or alternatively, the UE 505 may determine that the PHR is transmitted on the uplink control channel based, at least in part, on a determination that a resource block allocation for the uplink transmission satisfies a condition. Additionally or alternatively, the UE 505 may determine that the PHR be transmitted on the uplink control channel based, at least in part, on a determination that the uplink control information, which is loaded into the uplink control channel uplink, are of a specific type. In this way, the UE 505 can transmit the PHR on the uplink control channel when conditions are favorable for such transmission (for example, the uplink control channel traffic is low, there are enough RBs to load the PHR and / or similar).
[0092] [0092] In some respects, a PHR can be triggered when the UE 505 does not have a signal to transmit on the uplink transmission and / or has only a subset of the plurality of signals for transmission. In that case, the UE 505 can use one or more nominal signal configurations, which correspond to one or more signals, to determine the dynamic power reserve value. In some respects, a plurality of different nominal signal configurations may correspond to a plurality of signals. For example, a nominal signal configuration for an uplink control channel signal can include a specific format (e.g., a PUCCH format) and / or the like. Additionally or alternatively, a nominal signal configuration for an uplink data channel signal may include a specific modulation and encryption (MCS) scheme, a specific code rate and / or the like. Additionally or alternatively, a nominal signal configuration for an SRS may include a specific bandwidth for the SRS, a specific number and / or combination of SRS tones, a specific tone spacing and / or the like. In some respects, different signal combinations may correspond to different nominal signal configurations. In some respects, a nominal signal configuration can be signaled to the UE 505 in a system information message, an RRC message, in a media access control (MAC) element, in link control information descending and / or similar. In this way, the UE 505 can report a dynamic power reserve value when the UE 505 has no information to transmit.
[0093] [0093] Additionally or alternatively, when the UE 505 does not have a signal to transmit on the uplink transmission, the UE 505 can use a reference beam (for example, a standard beam) to determine the dynamic power reserve value. In some respects, different reference beams can be used for different signals, and the reference beam can be determined based, at least in part, on a signal associated with the PHR. In some respects, the reference beam can be determined as a function of time (for example, using a partition index). In this way, the UE 505 can transmit PHRs that correspond to all the different configured beams. In addition or alternatively, the reference beam (for example, a configuration for the reference beam) can be signaled to the UE 505 in an RRC message, in a MAC control element, in downlink control information and / or the like. In this way, the UE 505 can report a dynamic power reserve value when the UE 505 has no information to transmit.
[0094] [0094] Additionally or alternatively, the PHR can be associated with multiple repetitions of the uplink transmission. For example, uplink transmission can be repeated (for example, on different partitions) to increase reliability. In some cases, the dynamic power reserve value may change through different repetitions (for example, when the UE 505 receives a transmit power command from base station 510 between repetitions). However, a MAC control element can be maintained (for example, kept the same) through different repetitions. In this case, if the reported dynamic power reserve value associated with the multiple repetitions corresponds only to the first repetition, this leads to an inaccurate representation of the dynamic power reserve through multiple repetitions when there is a difference in the uplink transmissions that include the multiple repetitions.
[0095] [0095] Thus, for the most accurate dynamic power reserve report, the dynamic power reserve value can be determined based, at least in part, on several repetitions associated with the uplink transmission. Additionally or alternatively, the dynamic power reserve value may be based, at least in part, on one or more signals included in the multiple repetitions. For example, if there are many repetitions (for example, more than one limit), but only one of the repetitions (for example, the first) or some repetitions (for example, less than a limit) are multiplexed by frequency division with a signal (for example, an SRS), then the UE 505 can exclude the values associated with the specific signal when determining the dynamic power reserve value. Additionally or alternatively, if a majority or some limit number of repetitions includes at least two signals (for example, a PUCCH signal and a PUSCH signal), then the UE 505 can include the value associated with those signals when determining the value dynamic power reserve. In this way, the UE 505 can more accurately report a dynamic power reserve value associated with multiple repetitions.
[0096] [0096] In some respects, the UE 505 may determine the dynamic power reserve value based, at least in part, on a beam-specific power limitation associated with the UE 505. For example, in addition to specific power limitations at beam indicated by base station 510 (for example, a beam-specific Pmax value, beam-specific maximum power reduction value (MPR) and / or the like), the UE 505 may have restrictions on maximum transmit power in one or more beam directions. For example, such a construction includes a maximum allowable exposure restriction (MPE) to prevent too much radiation exposure to the human body. In some respects, the UE 505 can signal the specific beam-specific power limitation on the UE side for base station 510, and base station 510 can reconfigure one or more beam-specific power parameters (for example, Pmax and / or similar) for the affected beam (or bundles). Base station 510 can indicate the beam-specific power parameter (or parameters) reconfigured for the UE 505, and the UE 505 can use that parameter (or parameters) to determine the dynamic power reserve value for the affected beams. Additionally or alternatively, the UE 505 can autonomously reduce the maximum transmission power (Pcmáx) based, at least in part, on the specific power limitation on the beam on the UE side, thereby reporting a dynamic reserve value of lower power. In that case, the maximum transmission power (Pcmáx) for a beam may depend on a beam-specific Pmax value, a beam-specific MPR value, and / or a beam-specific displacement due to the specific beam limitation on the side UE (for example, a restriction on MEPs and / or the like).
[0097] [0097] In some respects, the UE 505 may report (for example, with the use of a PHR) a dynamic power reserve value, the reduced maximum transmission power, the maximum transmission power before the reduction and / or the specific beam offset to base station 510. In addition or alternatively, UE 505 can report (for example, using a PHR), a plurality of reports (for example, a plurality of PHRs) that correspond to a plurality of beams (for example, one or more beams in addition to the beam used in a partition that includes a report). In some respects, the plurality of bundles can be identified in the plurality of reports using a plurality of bundle identifiers. Additionally or alternatively, the plurality of bundles can be identified implicitly, as in an order of the reports that correspond to the bundles. For example, a first report can correspond to a first beam (for example, a control beam), a second report can correspond to a second beam (for example, a data beam) and / or the like. Such ordering can be indicated, for example, in an RRC message, a MAC, DCI and / or similar control element.
[0098] [0098] In some respects, the transmission of a PHR can be triggered based, at least in part, on a change in a specific power limitation to the beam on the UE side that specifies a limit. In this way, the UE 505 can notify the base station 510 of the power restrictions in the UE 505, and can modify the programming and / or beam management accordingly. The limit itself can be beam specific and can be configured by RRC, MAC-CE or DCI, for example, when the beam is configured.
[0099] [0099] The above methods related to reporting one or more beam-specific PHRs possibly based on beam-specific path loss triggers may also extend to the waveform-specific PHR report, or any combination of PHR reporting specific to waveform, specific to channel and / or specific to beam. Some or all of the parameters that regulate the calculation of PHR, including Pemáx configured by network, MPR, Pcmáx determined by UE that is reported for Pcmáx and MPR, and / or transmission power for transmitted signals, could be dependent on the form of wave to be used for the transmitted signal, for example, if the waveform is CP-OFDM or DFT-s-OFDM.
[0100] [0100] When reporting PHR for partitions where there is no transmitted signal, a nominal transmission waveform (for example, DFT-s-OFDM) could be used. In addition or alternatively, multiple PHRs could be reported, one for each possible waveform type. The type of waveform for each PHR could be explicitly stated as part of the PHR or implicitly determined by the ordering of the PHRs. Furthermore, the PHR report itself could be triggered based, at least in part, on the type of waveform. For example, a new PUSCH packet may include PHR under certain combinations of the waveform to be used for that packet and the waveform that was used for the forward uplink transmission, or for the forward uplink PUSCH transmission. . For example, PHR can be reported aperiodically whenever the PUSCH waveform changes, or only when it changes from DFT-s-OFDM to CP-OFDM. If the waveform changes during a PUSCH HARQ retransmission, this may constitute a trigger to transmit PHR aperiodically in the next PUSCH packet, or with the next PUCCH transmission, or with any of those that come before.
[0101] [0101] Additionally or alternatively, the PHR transmission can be triggered aperiodically satisfying the conditions. For example, if the UE 505 received a large PUSCH grant, but did not have enough data to send in the PUSCH grant, the UE 505 can populate the package with PHR reports for multiple partitions, beams, waveforms, report types PHR, channel types, or any combination thereof. In addition or alternatively, the PHR transmission can be dynamically triggered by base station 510 with the use of an aperiodic indication. For example, the trigger could be in the DCI programming for an uplink data channel (for example, PUSCH), in the DCI programming of a downlink data channel (for example, PDSCH) and a corresponding ACK in a uplink control channel (for example, PUCCH), on the MAC-CE of the programmed uplink data channel (for example, PDSCH) and / or the like.
[0102] [0102] In some respects, transmission of the PHR may be periodic. Additionally or alternatively, PHR transmission can be triggered aperiodically. For example, transmission of the dynamic power reserve report can be triggered based, at least in part, on a change in travel loss, detected through the UE 505, which satisfies a limit. In some respects, the change in path loss may be beam specific. In this case, the limit can be beam specific. Additionally or alternatively, the transmission of the PHR can be triggered for a specific beam. Additionally or alternatively, a nominal signal configuration and / or a reference beam to be used to determine the dynamic power reserve value can be determined based, at least in part, on the beam that activated the trigger based on loss of travel . In this way, PHRs can be triggered for specific beams based on network conditions, thereby improving performance when network conditions are poor.
[0103] [0103] As indicated above, Figure 5 is provided as an example only. Other examples are possible and may differ from what was described in relation to Figure 5.
[0104] [0104] Figure 6 is a diagram that illustrates another 600 example of dynamic power reserve report in Novo Rádio, according to various aspects of the present disclosure.
[0105] [0105] As shown in Figure 6, an UE 605 can communicate with a base station 610 to perform the dynamic power reserve report. In some respects, UE 605 may correspond to one or more UEs described anywhere in this document, such as UE 120 in Figure 1, UE 505 in Figure 5 and / or the like. Additionally or alternatively, base station 610 can correspond to one or more base stations described anywhere in the present document, such as base station 110 of Figure 1, base station 510 of Figure 5 and / or the like.
[0106] [0106] As shown by numeric reference 615, the UE 605 can generate a dynamic power reserve (PHR) report, as described in more detail above in combination with Figure 5. For example, the UE 605 can determine one or more signals, of a plurality of signals, to be transmitted in an uplink transmission, and can determine a maximum transmission power based, at least in part, on one or more signals. Different signals from the plurality of signals may correspond to different maximum transmission powers. UE 605 can generate PHR based, at least in part, on maximum transmission power, as described above in combination with Figure
[0107] [0107] As shown by numeric reference 620, UE 605 can transmit the PHR on an uplink control channel or as part of the uplink control (UCI) information transmitted on an uplink data channel. In some ways, the uplink control channel can be a PUCCH, as shown. Additionally or alternatively, the uplink data channel can be a PUSCH, as shown. In some aspects, the UE 605 can transmit the PHR on the uplink control channel. In some aspects, the UE 605 can transmit the PHR on the uplink data channel, as part of the UCIs, without uplink data (for example, as a UCI only transmission on the PUSCH). In some aspects, the UE 605 can transmit the PHR on the uplink data channel, as part of the UCIs, with uplink data (for example, as UCI on the PUSCH together with the PUSCH data).
[0108] [0108] Additionally or alternatively, the UE 605 can transmit the PHR as part of a MAC header that is included with a null data packet and transmitted on the uplink data channel. For example, in LTE, if there is a PUSCH payload, then the PHR can be transmitted as part of the MAC header for that PUSCH payload. In NR, the UE 605 can transmit an empty PUSCH payload (for example, a null data packet) with a MAC header used to load the PHR.
[0109] [0109] In some respects, the UE 605 can determine whether to transmit the dynamic power reserve report on the uplink control channel. For example, in some respects, the UE 605 can make this determination based, at least in part, on an uplink control channel format. Additionally or alternatively, the UE 605 can make this determination based, at least in part, on a payload size of an uplink transmission used to generate the dynamic power reserve report. Additionally or alternatively, the UE 605 can make this determination based, at least in part, on a resource block allocation for the uplink transmission. Additionally or alternatively, the UE 605 can make this determination based, at least in part, on one or more types of UCIs that are loaded into the uplink control channel. In this way, the UE 605 can transmit the PHR on the uplink control channel when conditions are favorable for such transmission (for example, uplink control channel traffic is low, there are enough RBs to load the PHR and / or similar).
[0110] [0110] As indicated above, Figure 6 is provided as an example only. Other examples are possible and may differ from what has been described in relation to Figure 6.
[0111] [0111] Figure 7 is a diagram illustrating an example 700 of power control of audible reference signal (SRS) in Novo Rádio, according to various aspects of the present disclosure.
[0112] [0112] As shown in Figure 7, a UE 705 can communicate with a base station 710 to perform SRS communication. In some respects, UE 705 may correspond to one or more UEs described anywhere in this document, such as UE 120 in Figure 1, UE 505 in Figure 5, UE 605 in Figure 6 and / or the like. Additionally or alternatively, base station 710 can correspond to one or more base stations described anywhere in this document, such as base station 110 in Figure 1, base station 510 in Figure 5, base station 610 in Figure 6 and / or the like.
[0113] [0113] As shown by numerical reference 715, UE 705 can determine one or more power parameters that contribute to a transmission power level for an SRS. In some respects, the one or more power parameters may include a beam-specific SRS parameter. Additionally or alternatively, the one or more power parameters may include an SRS power shift value. In some respects, the SRS power shift value may be beam specific. Additionally or alternatively, the one or more power parameters may include a fractional path loss value for the SRS. In some respects, the fractional path loss value for the SRS may differ from a fractional path loss value associated with an uplink data channel.
[0114] [0114] As shown by numerical reference 720, the one or more power parameters can be configured differently for different types of SRS transmissions. A type of SRS transmission may include, for example, a beam-scanning SRS transmission, a beam-specific SRS transmission and / or the like. A beam-scanning SRS transmission may refer to an SRS transmission that is transmitted in multiple (for example, all) beams, as with the use of a beam-scanning pattern. A beam-specific SRS transmission can refer to an SRS transmission that is transmitted on a specific beam. In some respects, the UE 705 can determine a type of SRS transmission, and can determine one or more power parameters based, at least in part, on the type of SRS transmission.
[0115] [0115] As additionally shown by the numerical reference 720, in some respects, if the SRS transmission is a beam-scanning SRS, then the UE 705 can use the same SRS power displacement value for all beams through which the beam scan SRS is to be transmitted. In this way, the beam specific power limitations on the UE side (for example, MPE restrictions) can be precisely reflected in the beam SINR as received by the base station 710. Additionally or alternatively, if the SRS transmission is an SRS beam scan, then the UE 705 can set a fractional path loss value to zero for the beam scan SRS. This is due to the fact that the loss of downlink path may not accurately reflect the uplink channel condition when the uplink beam scan is used in a non-reciprocal scenario.
[0116] [0116] As additionally shown by means of numerical reference 720, in some respects, if the SRS transmission is a beam-specific SRS, then the UE 705 can use a beam-specific SRS power shift value for a beam through which the beam-specific SRS is to be transmitted. In this way, the SINR of the beam can be reflected more precisely. Additionally or alternatively, if the SRS transmission is a beam-specific SRS, then the UE 705 can set a fractional path loss value to a value greater than zero for the beam-specific SRS. In this case, there may be specific beam reciprocity between the uplink and downlink channels, which can be taken into account with the use of a fractional path loss value greater than zero.
[0117] [0117] As shown by numerical reference 725, UE 705 can determine the transmission power level for the SRS based, at least in part, on one or more power parameters. For example, the UE 705 can determine the transmit power level as a minimum of the maximum transmit power for the UE 705 (for example, Pcmáx), which can correspond to the SRS (as described anywhere in this document in combination with Figure 5), and a sum of one or more of the fractional path loss value, the SRS power displacement value, a bandwidth value (for example, based, at least in part, on the number of resource blocks used for SRS), accumulated transmit power control commands, a SINR target value and / or the like.
[0118] [0118] As shown by numeric reference 730, UE 705 can transmit the SRS using the transmit power level. In some respects, if the SRS is a beam-specific SRS, then the UE 705 can transmit the SRS on the specific beam. In some respects, if the SRS is a beam-scanning SRS, then the UE 705 can transmit the SRS in multiple beams using a beam-scanning pattern. The UE 705 can transmit the SRS using the transmission power determined as described above. In this way, beam-specific and / or signal-specific power control can be used for the SRS to justify transmissions of specific types of signals using specific beams.
[0119] [0119] As indicated above, Figure 7 is provided as an example only. Other examples are possible and may differ from what was described in relation to Figure 7.

In some respects, the transmission of the dynamic power reserve report is triggered for a specific beam.

Additional or alternatively, two or more of the process blocks 800 can be carried out in parallel.
