DRAFT CONTROL RESOURCE SET GROUP TO IMPROVE DEVICES, SYSTEMS AND COMMUNICATIONS NETWORKS PRIORITY [0001] This application claims priority for and the benefit of US Provisional Patent Application No. 62 / 455,574, filed on February 6, 2017 and titled CONTROL RESOURCE SET GROUP DESIGN FOR NR; and US Non-Provisional Patent Application No. 15 / 888,950, entitled, CONTROL RESOURCE SET GROUP DESIGN FOR IMPROVED COMMUNICATIONS DEVICES, SYSTEMS, AND NETWORKS, filed on February 5, 2018, the disclosures of which are hereby incorporated by reference here in their entirety as if completely presented below and for all applicable purposes.
FIELD OF TECHNIQUE [0002] Aspects of the present disclosure generally refer to wireless communication systems, and more particularly, to methods, systems, devices, and networks providing improved wireless communications and resource utilization through control resource sets (Coresets ).
INTRODUCTION [0003] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, message, broadcast, and the like. These wireless networks can be multiple access networks capable of supporting multiple users by sharing available network resources. Such networks, which are usually multiple access networks, support communications for multiple users by sharing
Petition 870190072920, of 07/30/2019, p. 6/102
2/57 available network resources.
[0004] A wireless communication network can include a number of base stations or Bs node that can support communication to various user devices (UEs). A UE can communicate with a base station via downlink and uplink. The downlink (or direct link) refers to the communication link from the base station to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the base station.
[0005] A base station can transmit data and control information on the downlink to a UE and / or can receive data and control information on the uplink from the UE. In the downlink, a transmission from the base station may encounter interference due to transmissions from neighboring base stations or from other wireless radio frequency (RF) transmitters. In the uplink, a transmission from the UE may encounter interference from uplink transmitters from other UEs that communicate with neighboring base stations or from other wireless RF transmitters. This interference can impair performance on both the downlink and the uplink.
[0006] As the demand for mobile broadband access continues to increase, the possibilities for interference and congested networks grow with more UEs accessing long-range wireless communication networks and more short-range wireless systems being deployed in communities . Research and development continues to promote wireless communication technologies not only to meet the growing demand for access to mobile broadband, but to promote and enhance the user experience with

DETAILED DESCRIPTION [0031] The detailed description presented
Petition 870190072920, of 07/30/2019, p. 10/152
11/57 below, in connection with the accompanying drawings, is intended to be a description of several possible configurations and is not intended to limit the scope of the disclosure. Instead, the detailed description includes specific details for the purpose of providing a complete understanding of the inventive material. It will be apparent to those skilled in the art that these specific details are not necessary in all cases and that, in some cases, well-known structures and components are shown in the form of a block diagram for clarity of presentation.
[0032] This disclosure generally refers to providing or participating in communication between two or more wireless devices in one or more wireless communication systems, also known as wireless communications networks. In various modalities, the techniques and apparatus can be used for wireless communication networks such as code division multiple access networks (CDMA), time division multiple access networks (TDMA), multiple division access networks frequency (FDMA), orthogonal FDMA networks (OFDMA), single carrier FDMA networks (SC-FDMA), long term evolution networks (LTE), GSM networks, as well as other communications networks. As described herein, the terms networks and systems can be used interchangeably according to the particular context.
[0033] A CDMA network, for example, can implement radio technology, such as universal access to terrestrial radio (UTRA), CDMA2000 and the like. UTRA includes CDMA broadband (W-CDMA) and low chip rate (LCR). CDMA2000 covers the IS-2000, IS-95 and IS-856 standards.
[0034] A TDMA network can, for example,
Petition 870190072920, of 07/30/2019, p. 10/162
12/57 implement a radio technology such as the Global Mobile Communications System (GSM). An organization called Partnership Project 3 Generation (3GPP) defines standards for radio access network (RAN) GSM EDGE (enhanced data rates for GSM Evolution), also known as GERAN. GERAN is the radio component of GSM / EDGE, together with the network that joins the base stations (for example, the Ater and Abis interfaces) and the base station controllers (interfaces A, etc.). The radio access network represents a component of a GSM network, through which phone calls and packet data are routed to and from the public switched telephone network (PSTN) and the Internet to and from subscriber handsets, also known as terminals user or UEs. The mobile operator network may comprise one or more GERANs, which can be coupled to UTRANs in the case of a UMTS / GSM network. A network of operators may also include one or more LTE networks and / or one or more other networks. The various types of different networks can use different radio access technologies (RATs) and RANs.
[0035] An OFDMA network may, for example, implement radio technology such as UTRA (E-UTRA), the Institute of Electrical and Electronic Engineers (IEEE) 802.11, IEEE 802.16, IEEE 802.20, flash-OFDM and the like. U E-UTRA and GSM are part of the universal mobile telecommunications system (UMTS). In particular, LTE is a launch of UMTS that uses E-UTRA. UTRA, E-UTRA, GSM, UMTS and LTE are described in documents provided by the 3GPP, and CDMA2000 is described in documents from an organization named Partnership Project 3 Generation 2 (3GPP2). These various radio technologies and standards are known
Petition 870190072920, of 07/30/2019, p. 10/172
13/57 or are being developed. For example, 3GPP is a collaboration between groups of telecommunications associations that aims to define a globally applicable third generation (3G) cell phone specification. The 3GPP LTE is a 3GPP project that aims to improve the mobile telephony standard of the universal mobile telecommunications system (UMTS). 3GPP can define specifications for the next generation of mobile networks, mobile systems and mobile devices.
[0036] For clarity, certain aspects of the apparatus and techniques can be described below with reference to exemplary implementations of LTE or in an LTE-centric way, and LTE terminology can be used as illustrative examples in portions of the description below. But the description is not intended to be limited to LTE applications. In fact, the present disclosure refers to the shared access to the wireless spectrum between networks, using different radio access technologies or aerial radio interfaces.
[0037] In addition, it should be understood that, in operation, wireless communication networks adapted according to the concepts here can operate with any combination of licensed or unlicensed spectrum depending on loading and availability. Consequently, it will be apparent to a person skilled in the art that the systems, apparatus and methods described herein can be applied to other communications systems and applications than the particular examples provided.
[0038] Although aspects and modalities are described in this application by illustrating some examples, persons skilled in the art will understand that additional implementations and use cases may arise in
Petition 870190072920, of 07/30/2019, p. 10/182
14/57 many different arrangements and scenarios. The innovations described here can be implemented on many different types of platforms, devices, systems, shapes, sizes, packaging arrangements. For example, modalities and / or uses can be carried out through integrated chip modalities and other devices not based on module components (eg, end-user devices, vehicles, communication devices, computer devices, industrial equipment, devices purchase / sale, artificial intelligence (AI) devices, etc.). Although some examples may or may not be specifically targeted to use cases or applications, a wide variety of applicability of the described innovations may occur. Implementations can range from chip-level components or modular components to non-modular, non-chip-level implementations, in addition to aggregated, distributed or original equipment manufacturer (OEM) devices or systems incorporating one or more aspects of the described innovations. In some practical contexts, devices that incorporate aspects and features described may also necessarily include additional components and features for the implementation and practice of claimed and described modalities. For example, wireless signal transmission and reception necessarily includes several components for analog and digital purposes (for example, hardware components, including antennas, RF chains, power amplifiers, modulators, buffer, processor (processors), interleaver, adders / verifiers, etc.). It is intended that the innovations described here can be practiced in a
Petition 870190072920, of 07/30/2019, p. 10/192
15/57 wide variety of devices, chip level components, systems, distributed arrangements, end-user devices, etc. of variable sizes, shapes and constitution.
[0039] Figure 1 shows wireless network 100 for communication according to some modalities. Although the technology debate for this disclosure is provided in relation to an LTE-A network (shown in Figure 1), this is for illustrative purposes. The principles of the disclosed technology can be used in other network implementations, including fifth generation (5G) radio (NR) networks. As appreciated by those skilled in the art, the components that appear in Figure 1 are likely to have related counterparts in other network arrangements.
[0040] Returning to Figure 1, the wireless network 100 includes a number of base stations, as can be understood by the next generation Bs node (gNB), here called gNBs 105 and other network entities. A gNB can be a station that communicates with the UEs and can also be referred to as a base station, a B node, an access point and the like. Each gNB 105 can provide communication coverage for a particular geographic area. In 3GPP, the term cell can refer to that specific geographic coverage area of a gNB and / or gNB subsystem that serves the coverage area, depending on the context in which the term is used. In implementations of wireless network 100 here, gNBs 105 can be associated with the same operator or different operators (for example, wireless network 100 can comprise a plurality of wireless carrier networks)
Petition 870190072920, of 07/30/2019, p. 10/20
16/57 and can provide wireless communications using one or more of the same frequencies (for example, one or more frequency bands in the licensed spectrum, unlicensed spectrum or a combination of them) as a neighboring cell.
[0041] A gNB can provide communication coverage for a macro cell or a small cell, such as a peak cell or a femto cell, and / or other cell types. A macro cell generally covers a relatively large geographic area (for example, several kilometers in radius) and can allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a peak cell, would generally cover a relatively smaller geographic area and may allow unrestricted access by UEs with service subscriptions with the network provider. A small cell, such as a femto cell, would generally also cover a relatively small geographical area (for example, a house) and, in addition to unrestricted access, can also provide restricted access for UEs that have an association with the femto cell (for example, UEs in a closed subscriber group (CSG), UEs for home users and the like). A gNB for a macro cell can be called a gNB macro. A small cell gNB can be termed as a small cell gNB, a gNB peak, a gNB femto, or a home gNB. In the example shown in Figure 1, gNBs 105a, 105b and 105c are macro-gNBs for macro-cells 110a, 110b and 110c, respectively. 105x, 105y, and 105z gNBs are small cell gNBs, which may include peak or femto gNBs that provide service to small HOx, HOy, and IlOz cells,
Petition 870190072920, of 07/30/2019, p. 10/212
17/57 respectively. A gNB can support one or more cells (for example, two, three, four and the like).
[0042] Wireless network 100 can support synchronous or asynchronous operation. For synchronous operation, gNBs can have similar frame timing, and transmissions from different eNBs can be approximately time aligned. For asynchronous operation, gNBs may have different frame timings, and transmissions from different eNBs may not be time aligned.
[0043] UEs 115 are dispersed throughout the wireless network 100, and each UE can be stationary or mobile. It should be appreciated that although a mobile apparatus is commonly referred to as user equipment (UE) in standards and promulgated specifications for Partnership Project third generation (3GPP), such device can also be called by the skilled person in the art as a station (MS), a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a station mobile subscriber, access terminal (AT), mobile terminal, wireless terminal, remote terminal, handset, terminal, user agent, mobile client, customer or some other suitable terminology. Within this document, a mobile device or UE does not necessarily need to be able to move and can be stationary. Some non-limiting examples of a mobile device, as they may comprise modalities of one or more UEs 115, include a cell phone, a cell phone (cell phone), a smart phone, a protocol phone
Petition 870190072920, of 07/30/2019, p. 10/22
18/57 session initiation (SIP), a laptop computing device, a personal computer (PC), a notebook, a netbook, a smart book, a tablet computing device and a personal digital assistant (PDA). A mobile device can additionally be an Internet of Things (loT) device, such as an automotive or other transport vehicle, a satellite radio, a global positioning system (GPS) device, a logistics controller, a drone, a multi -copter, a quad-copter, an intelligent energy or security device, a solar or solar panel, municipal lighting, water or other infrastructure; industrial automation and business devices; consumer and wearable devices such as glasses, a wearable camera, a smart watch, a health or fitness tracker, a mammal implantable device, gesture tracking device, medical device, a digital audio player (for example, MP3 player ), a camera, game console, etc .; and digital home or smart home devices such as home audio, video and multimedia devices, an instrument, a sensor, a vending machine, smart lighting, a home security system, a smart meter, etc. A mobile device, such as UEs 115, may be able to communicate with gNBs macros, gNBs peaks, gNBs femtos, relays and the like. In Figure 1, a lightning bolt (for example, communication links 125) indicates wireless transmissions between a UE and a gNB in service, which is a gNB designated to serve the UE on the downlink and / or uplink, or desired transmission between gNBs. Although backhaul communication 134 is illustrated as wired backhaul communications that can occur between
Petition 870190072920, of 07/30/2019, p. 10/23
19/57 gNBs, it should be appreciated that backhaul communications can, additionally or alternatively, be provided by wireless communications.
[0044] Figure 2 shows a block diagram of a base station / gNB 105 and UE 115 project, which can be one of the base stations / gNBs and one of the UEs in Figure 1. For a restricted association scenario, gNB 105 can be small cell gNB 105z in Figure 1, and UE 115 can be UE 115z, which, to access small gNB 105z cells, would be included in a list of accessible UEs for small cell gNB 105z. The gNB 105 can also be a base station of some other type. The gNB 105 can be equipped with antennas 234a to 234t, and the UE 115 can be equipped with antennas 252a to 252r.
[0045] In gNB 105, transmission processor 220 can receive data from data source 212 and controller / processor control information 240. Control information can be for the physical broadcast channel (PBCH), format indicator channel physical control (PCFICH), physical hybrid ARQ indicator channel (PHICH), physical downlink control channel (PDCCH), etc. Data can be for the physical downlink shared channel (PDSCH), etc. The transmission processor 220 can process (e.g., coding and symbol map) the control data and information to obtain control symbols and symbols data, respectively. The transmission processor 220 can also generate reference symbols, for example, for the primary sync signal (PSS), secondary sync signal (SSS) and cell-specific reference signal. The MIMO processor (multiple input
Petition 870190072920, of 07/30/2019, p. 10/242
20/57 multiple output) transmission (TX) 230 can perform spatial processing (for example, pre-coding) on data symbols, control symbols and / or reference symbols, if applicable, and can provide output symbol streams to modulators (MODs) 232a to 232t. Each modulator 232 can process a stream of respective output symbols (for example, for OFDM, etc.) to obtain an output sample stream. Each modulator 232 can additionally or alternatively process (for example, convert to analog, amplify, filter and upwardly convert) the output sample stream to obtain a downlink signal. Downlink signals from modulators 232a to 232t can be transmitted through antennas 234a to 234t, respectively.
[0046] In UE 115, antennas 252a to 252r can receive downlink signals from eNB 105 and can provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each desmodulator 254 can condition (for example, filter, amplify, negatively convert and digitize) a respective received signal to obtain input samples. Each demodulator 254 can further process the input samples (for example, for OFDM, etc.) to obtain received symbols. The MIMO 256 detector can obtain symbols received from all demodulators 254a to 254r, perform MIMO detection on received symbols, if applicable, and provide detected symbols. The receiving processor 258 can process (e.g., demodulate, deinterleave and decode) the detected symbols, provide decoded data to UE 115 for data storage 260, and provide decoded control information to controller / processor 280.
Petition 870190072920, of 07/30/2019, p. 10/252
21/57 [0047] In the uplink, in the UE 115, the transmission processor 264 can receive and process data (for example, for the physical uplink shared channel (PUSCH)) from data source 262 and control information (for example , for the physical uplink control (PUCCH) channel of controller / processor 280. Transmission processor 264 can also generate reference symbols for a reference signal. The symbols of the transmission processor 264 can be pre-encoded by the MIMO TX 266 processor if applicable, still processed by modulators 254a to 254r (for example, for SCFDM, etc.), and transmitted to gNB 105. In gNB 105, the signals Uplink signals from UE 115 can be received by antennas 234, processed by demodulators 232, detected by MIMO detector 236 if applicable, and further processed by receiving processor 238 to obtain decoded data and control information sent by UE 115. Processor 238 can provide the decoded data for data deposit 239 and the decoded control information for the controller / processor 240.
[0048] Controllers / processors 240 and 280 can direct the operation on gNB 105 and UE 115, respectively. Controller / processor 240 and / or other processors and modules in the gNB 105 can perform or direct the execution of various processes for the techniques described here. Controllers / processor 280 and / or other processors and modules in the UE 115 may also perform or direct the execution of functionality described and illustrated with reference to Figures 3 to 8, and / or other processes for the techniques described here.

[0049] With reference to Figure 3, a block diagram illustrating aspects of the Coresets configuration is shown. For NR 5G networks, a Coreset can be used in several ways. In Figure 3, a partition 310 is shown. As illustrated in Figure 3, within partition 310, a plurality of Coresets have been defined, where the plurality of Coresets includes a first Coreset 320, a second Coreset 330, a third Coreset 340, and a fourth Coreset 350. As illustrated in Figure 3 , the first Coreset 320, the second Coreset 330, and the fourth Coreset 350 can have almost empty Coresets (for example, contain a significant number of unused resources), while the third Coreset 340 can be a busy Coreset (for example, contain little or no unused resources, which may be due to a high number of downlink and / or uplink leases, etc.). Coresets can have a length of Coreset 360. In modalities, the length of Coreset 360 can correspond to several symbols (for example, one symbol, two symbols, etc.) within the partition that can be used by each Coreset. Coresets can be designed to transmit common physical downlink control channel (PDCCH) information and can be used to transport an indicator type partition, control format indicator (CFI) information (for example, information that indicates various symbols used to transport Coresets), other types of information (for example, downlink control indicator information
Petition 870190072920, of 07/30/2019, p. 10/272
23/57 (DCI), etc.), or a combination thereof. The indicator type partition can be common in all Coresets. In modalities, the CFI can be different between Coresets.
[0050] If different CFI information is used for different Coresets, the common PDCCH may need to be transmitted in each of the coresets. However, processing such a transmission can be expensive. In addition, if a single CFI is used, the CFI may be the worst case in all Coresets. The blind decoding economy of having a single indication of CFI may not provide many benefits as it prevents narrowband monitoring for UEs, which in turn increases energy consumption by UEs.
[0051] As an alternative to such a broadband transmission of Coresets, a narrow band monitoring concept can be used by the UE to monitor a narrow radio frequency band. For example, a UE can monitor only one UE-specific Coreset. However, if the common PDCCH is transmitted only in the common Coreset, to monitor that channel, it may be necessary for the UE to have a broadband to cover this Coreset and its own Coreset specific to the UE. Such a use case may not, in fact, provide narrowband monitoring and the power consumption of the UE may not be satisfactory.
[0052] Furthermore, a use case for the common PDCCH is the partition type indicator for the neighboring UE to detect. If the neighboring UE is in a Coreset specific to the UE, to monitor a common Coreset from the neighboring gNB, it may be necessary for the UE to operate in broadband mode,
Petition 870190072920, of 07/30/2019, p. 10/282
24/57 which can remove the benefit of using narrowband radio frequencies.
[0053] As shown above, each of the use cases mentioned above has contradictory needs.
For some use cases, it may be beneficial to have the common PDCCH in each Coreset, repeat the partition type indicator, and use by Coreset CFI. For other use cases, it may be beneficial to have a single common PDCCH only in the common Coreset, which can reduce control overhead.
[0054] Figure 4 is a block diagram that illustrates aspects of the configuration of Coreset groups according to a modality. A solution to the aforementioned contradictory needs can be achieved by defining Coreset groups. In Figure 4, a partition 410 is shown. As shown in Figure 4, a plurality of Coresets can be defined. The plurality of Coresets can include a first Coreset 420, a second Coreset 430, a third Coreset 440 and a fourth Coreset 450. The plurality of Coresets can be grouped to form one or more Coreset groups. For example, in Figure 4, the first Coreset 420 and the second Coreset 430 can form a first group of Coreset and the third Coreset 440 and the fourth Coreset 450 can form a second group of Coreset. Coresets can have a Coreset 460 length.
[0055] In modalities, the length of Coreset 460 can correspond to several symbols (for example, one symbol, two symbols, etc.) within the partition that can be used by each Coreset. In variable modalities,
Petition 870190072920, of 07/30/2019, p. 10/29
25/57 different Coresets and / or groups of Coreset can use different numbers of symbols. For example, the first Coreset 420 and the second Coreset 430 can use a symbol, leaving an unused symbol inside the first Coreset 420 and the second Coreset 430, and the third Coreset 440 and the fourth Coreset 450 can use two symbols, leaving no symbols not used within the third Coreset 440 and the fourth Coreset 450. Note that some features of the symbols associated with the Coreset 460 length may not be included in a Coreset. In modalities, these unused resources may include subcarriers within the symbols corresponding to the symbols used by the plurality of Coresets. The amount of unused resources within the symbols associated with the Coreset 460 length, as well as their positions (for example, frequencies) within the partition can vary depending on a particular configuration of partition 410 and its Coresets.
[0056] To facilitate the narrowband monitoring of Coreset groups, Coresets within a Coreset group can be located in frequency domain. For example, in Figure 4, the first Coreset group includes the first Coreset 420 and the second Coreset 430, and the second Coreset group includes the third Coreset 440 and the fourth Coreset 450. As shown in Figure 4, the first Coreset 420 and the second Coreset 430 (for example, the first group of Coreset) are positioned relatively in relation to each other in relation to their frequencies. This means that the formation of the first group of Coreset using the first Coreset 420 and the second Coreset 430
Petition 870190072920, of 07/30/2019, p. 10/30
26/57 locate the first Coreset 420 and the second Coreset 430 at a narrower frequency band than if the first Coreset group was formed using the first Coreset 420 and the third Coreset 440 or using the first Coreset 420 and the fourth Coreset 450. Thus, an UE that is to monitor the first group of Coreset or the second group of Coreset can use a narrowband monitoring technique, thereby reducing the energy consumption of the UE. For example, if a transmission covers a frequency spectrum of 100 MHz, narrowband monitoring can facilitate monitoring of 20 MHz from the 100 MHz used by the transmission. Note, however, that this example has been provided for purposes of illustration, rather than limitation, and that narrowband monitoring may use a larger or smaller portion of the frequency spectrum, depending on several factors, such as traffic load , subcarrier settings, and other factors. To illustrate, depending on the traffic load, a UE can sometimes use a broadband monitor, such as 100 MHz.
[0057] Additional improvements can also be made by configuring groups of Coreset according to the modalities. For example, in modalities, each group of Coreset can be configured to include a primary Coreset and at least one secondary Coreset. As shown in Figure 4, the first Coreset group includes the second Coreset 430 as a primary Coreset and the first Coreset 420 as a secondary Coreset, and the second Coreset group includes the third Coreset 440 as a primary Coreset and the fourth Coreset 450 as a secondary Coreset.
Petition 870190072920, of 07/30/2019, p. 10/312
27/57
It is observed that although Figure 4 only illustrates groups of Coreset that include a single secondary Coreset, in modalities, a group of Coreset can be defined that includes two or more secondary Coresets. In modalities, the primary Coreset of a particular Coreset group can be configured to provide a common search space for the UEs configured for the particular Coreset, and the secondary Coreset can be configured to provide a specific search space for UEs for configured UEs for the particular Coreset. In modalities, the common PDCCH may be transmitted in the primary Coreset of one or more Coreset groups, and may not be transmitted in the secondary Coresets. In modalities, radio resource control (RRC) signaling can be used to signal the configuration of the Coreset group assigned to the UE. From the UE perspective, it only needs to monitor Coresets within the Coreset Group for which it is configured, which includes monitoring only one primary Coreset.
[0058] In modalities, CFI information can be common in all Coresets in a group of Coreset. For example, CFI information for the first group of Coreset can be common for both the first Coreset 420 and the second Coreset 430, and CFI information for the second group of Coreset can be common for both the third Coreset 440 and for the fourth Coreset 450. It is noted that in some modalities, the CFI information may be the same for all Coreset groups, while in other modalities, the CFI information for different Coreset groups may be different.
Petition 870190072920, of 07/30/2019, p. 10/32
28/57
For example, as shown in Figure 4, the first group of Coreset can use one symbol and the second group of Coreset can use two symbols. Thus, when the CFI presents a worst case scenario within a group of Coreset, in general, it may not be as bad as the worst case in all Coresets.
[0059] Defining Coreset groups that include a primary Coreset and at least a secondary Coreset can provide energy savings, although the energy savings may not be as much as coverage for a single Coreset specific only to the UE. However, the energy savings will still be better than it would otherwise be achieved if the UE had to monitor a Coreset specific to the UE and a common Coreset, as described with reference to Figure 3 above.
[0060] To monitor neighboring cells, RRC signaling can be used to notify the UE of one or more Coresets of a neighboring cell. For example, in modalities, a list of primary Coresets can be provided to the UE by a service cell. The UE can then choose a primary Coreset from the neighboring cell that is from its own monitored Coreset (monitored Coresets), thereby allowing the UE to use a relatively narrow band to monitor its own Coreset (own Coresets) and the primary Coreset from the neighboring cell (for example, a cell provided by a neighboring gNB). In some embodiments, gNB can select the best primary Coreset from neighboring gNB and inform the UE of the selected primary Coreset of the neighboring gNB, instead of sending a list of primary Coresets to the neighboring gNB for the UE. In
Petition 870190072920, of 07/30/2019, p. 10/33
29/57 modalities, the gNBs of the network can coordinate to have the same primary Coresets, which can prevent increased bandwidth when monitoring neighboring gNBs. Using narrowband monitoring facilitated by the modalities can allow energy savings to be achieved in the UE. In addition, the exchange of Coreset configuration information between gNBs can facilitate the mitigation of interference between neighboring gNBs. In modalities, the Coreset configuration information between neighboring gNBs can include information that indicates a partition format used by a particular gNB.
[0061] As shown above, configuring Coreset groups according to the modalities can provide several advantages. First, the UE only needs to monitor the primary Coreset and its own UE-specific Coreset (for example, the secondary Coreset). Second, by locating Coresets within a group of Coreset in the frequency domain, the UE can monitor a narrower bandwidth, reducing energy consumption in the UE. Third, configuring each group of Coreset to include a primary Coreset in which common PDCCH information can be transmitted effectively provides a case scenario in which common PDCCH information is transmitted in each Coreset. In other words, the modalities reach a compromise that provides excellent energy savings and, at the same time, effectively maintains a large common PDCCH. In some embodiments, one or more Coreset groups can include only a primary Coreset (for example, a Coreset group that does not include a secondary Coreset). This may not provide cost savings
Petition 870190072920, of 07/30/2019, p. 10/34
30/57 power, but can provide the lowest common overhead of the PDCCH.
[0062] As briefly explained above, a UE can be configured with RRC to know all the Coresets that gNB is using, along with the Coreset group structure, although the UE may only need to monitor the Coreset that it is configured to use. For a resource (for example, a resource element from partition 410) not included in one of the Coresets, if included in the UE resource allocation, the physical downlink shared channel (PDSCH) starts from the O symbol of partition 410 In modalities, PDCCH resources not used in Coresets can be reused. For example, unused PDCCH resources can be reused for PDSCH. In modalities, a DCI for granting a downlink can include a field to indicate the reuse of Coreset resources, and an RRC setting can be used to enable / disable this feature.
[0063] In Figure 4, a first illustrative embodiment of a resource reuse configuration in accordance with the present disclosure is shown. In particular, features 470, which have been shaded, include features that are not in any of the plurality of Coresets and features in empty symbols within each Coreset. For example, only the first symbol can be used within the first group of Coreset (for example, the first Coreset 420 and the second Coreset 430), allowing resources 422 within the second symbol of the first Coreset 420 and resources 432 within the second symbol of the second Coreset 430 to be reused. In one mode, a field can be included or added to the DCI information for a grant
Petition 870190072920, of 07/30/2019, p. 10/35
31/57 downlink to indicate the Coreset reuse configuration. In modalities, the field can include a subfield for each group of Coreset. This may require more bits when more groups of coreset are configured. Note that when each group of Coreset has the same CFI, a value for each group of Coreset can be used to indicate whether unused symbols within a group of Coreset are reusable.
[0064] In modalities, the contents of the subfield can have several values, each value indicating a reuse configuration. For example, a first value may indicate that none of the Coreset symbols or Coreset group are used for control information, a second value may indicate that a Coreset symbol or Coreset group is used for control information, and a third value can indicate that the total Coreset length of the Coreset or Coreset group is used for control information. This can allow the UE to determine whether the unused symbol within a Coreset or group of Coreset is present and reusable. In modalities, the subfields can be coded independently for each group of Coreset.
[0065] In modalities, another combination (for example, field value) may indicate that only the common PDCCH group is transmitted in the Coreset group, allowing the reuse of resources at the sub-Coreset level. For this special case, there may be no PDCCH transmission in the entire Coreset group (for example, including primary and secondary Coresets within the Coreset group), and only the common PDCCH in the group can be included in the first symbol. This
Petition 870190072920, of 07/30/2019, p. 36/102
32/57 allows the PDSCH of the UE to start from the first symbol in the control information, and the UE may only need to evaluate the correspondence around the common PDCCH group and the demodulation reference signal (DMRS) for the PDCCH group common.
[0066] In modalities, a single field can be used for all Coreset groups covered by the allocation of resources from the UE. This can reduce the amount of overhead associated with the control information. However, in such a scenario, the reuse of resources may not be optimal, as this common field needs to be the worst case of all the Coreset groups monitored by the UE.
[0067] As explained above, Figure 4 illustrates a modality of a resource reuse configuration that can be provided using a Coreset reuse field. As shown in Figure 4, in such a modality, the resource reuse field can indicate that all resources not included in any Coresets (for example, 470 resources) can be reused and, within each Coreset, resources associated with empty symbols (for example, resources 422, 432) can be reused. It is noted that, for the resources included in the second group of Coreset (for example, the group of Coreset that includes the third Coreset 440 and the fourth Coreset 450), no resource can be reused. This is because control information is carried over the total length of 460 (for example, two symbols are used to carry control information).
[0068] In modalities, a gNB (for example, one of the 105 gNBs illustrated and described in relation to Figure 1 or
Petition 870190072920, of 07/30/2019, p. 37/102
33/57
Figure 2) can determine a resource reuse setting for a transmission. The resource reuse setting can indicate a scheme for using or reusing unused resources from the transmission (for example, for PDSCH etc.). In modalities, the gNB can communicate the configuration of resource reuse for transmission to the UE. This may include configuring one or more fields of the control information included in the transmission, as described above. As explained above, in Figure 4, the scheme for using or reusing unused resources from the transmission can indicate that resources that are not assigned to one or more Coreset groups, such as resources 470, are reusable. In addition, the scheme for using or reusing unused resources from the transmission may indicate that resources within each Coreset associated with empty symbols (for example, resources 422, 432) can be reused. In embodiments, gNB can determine the resource reuse configuration based at least in part on one or more configurations in the Coreset group associated with a neighboring cell. This can mitigate interference for transmissions by the gNB and / or the neighboring gNB supplying the neighboring cell. As shown above, configuring Coreset groups according to modalities can facilitate the monitoring of Coresets narrowband by UEs, which reduce energy consumption, and can provide a mechanism to provide a common PDCCH. In addition, the modalities facilitate dynamic configuration of configurations / resource reuse schemes that can be adapted to each group of Coreset, thus improving the use of bandwidth.
Petition 870190072920, of 07/30/2019, p. 38/102
34/57 [0069] With reference to Figure 5, a block diagram that illustrates aspects of the configuration of Coreset groups for resource reuse according to the modalities is shown. As described above, a plurality of Coresets can be defined. As shown in the example illustrated in Figure 5, a plurality of defined Coresets can include a first Coreset 520, a second Coreset 530, a third Coreset 540 and a fourth Coreset 550. The plurality of Coresets can be grouped to form one or more groups of Coreset. For example, in Figure 5, the first Coreset 520 and the second Coreset 530 can form a first group of Coreset and the third Coreset 540 and the fourth Coreset 550 can form a second group of Coreset. Coresets can have a length of Coreset 560. In modalities, the length of Coreset 560 can correspond to several symbols (for example, one symbol, two symbols, etc.) within partition 510 that are used to supply Coreset. In modalities, different Coresets and / or groups of Coreset can use different numbers of symbols. For example, the first Coreset 520 and the second Coreset 530 can use a symbol, leaving an unused symbol inside the first Coreset 520 and the second Coreset 530, and the third Coreset 540 and the fourth Coreset 550 can use two symbols, leaving no unused symbols within the third Coreset 540 and the fourth Coreset 550. Note that some features of the symbols associated with the Coreset 560 length may not be included in a Coreset. In modalities, these unused resources may include subcarriers within the symbols used
Petition 870190072920, of 07/30/2019, p. 39/102
35/57 for the plurality of Coresets. The amount of unused resources within the symbols associated with the Coreset 560 length, as well as their positions (for example, frequencies) within partition 510 may vary depending on a particular configuration of partition 510 and its Coresets.
[0070] In Figure 5, an illustrative modality of a particular configuration of resource reuse is shown. In particular, the resource reuse configuration illustrated in Figure 5 indicates that all resources that are not included in any Coresets can be reused. For example, on partition 510, features 570, which have been shaded, illustrate features that are not included in any Coresets. Each of the 570 resources can be reused, such as for PDSCH or for other purposes. In addition, as shown in Figure 5, empty symbols within a Coreset may not be reused. Thus, in Figure 5, a scheme for using unused resources from the transmission can indicate that resources not assigned to any Coresets and / or Coreset groups can be reusable, and that resources associated with empty symbols within the one or more Coreset groups are not reusable. In modalities, the resource reuse configuration illustrated in Figure 5 can be used in scenarios where a UE has broadband allocation, such as when the UE is configured to monitor several Coresets and / or groups of Coreset covering a wide range of frequency, where at least one of the Coresets and / or groups of Coreset uses two (2) symbols. In such scenarios, the reuse field
Petition 870190072920, of 07/30/2019, p. 40/102
36/57 included in the DCI can include only a subfield to indicate the reuse configuration for the Coresets and / or Coreset groups monitored by the UE. When only one subfield is used, there may be no way to tell the UE that there are empty symbols in the other Coresets and / or groups of Coreset, which prevents the reuse of unused symbols. In embodiments, one or more resource reuse fields can be used to indicate the resource reuse configuration for partition 510, as described above with reference to Figure 4.
[0071] With reference to Figure 6, a block diagram that illustrates additional aspects of the configuration of Coreset groups for resource reuse according to the modalities is shown. As shown in Figure 6, a plurality of Coresets can be defined. The plurality of Coresets can include a first Coreset 620, a second Coreset 630, a third Coreset 640 and a fourth Coreset 650. The plurality of Coresets can be grouped to form one or more Coreset groups. For example, in Figure 6, the first Coreset 620 and the second Coreset 630 can form a first group of Coreset and the third Coreset 640 and the fourth Coreset 650 can form a second group of Coreset. Coresets can have a length of Coreset 660. In modalities, the length of Coreset 660 can correspond to several symbols (for example, one symbol, two symbols, etc.) within partition 610 that are used to supply Coreset. In different modalities Coresets and / or groups of Coreset can use different numbers of symbols. For example, the first Coreset 620 and the second Coreset 630 can
Petition 870190072920, of 07/30/2019, p. 41/102
37/57 use a symbol, leaving an unused symbol within the first Coreset 620 and the second Coreset 630, and the third Coreset 640 and the fourth Coreset 650 can use two symbols, leaving no unused symbols within the third Coreset 640 and the fourth Coreset 650. Note that some features of the symbols associated with the length of Coreset 660 may not be included in a Coreset. In modalities, these unused resources may include subcarriers within the symbols used by the plurality of Coresets. The amount of unused resources within the symbols associated with the length of Coreset 660, as well as their positions (for example, frequencies) within partition 610 may vary depending on a particular configuration of partition 610 and its Coresets.
[0072] In Figure 6, another modality illustrating a particular configuration of resource reuse is shown. In particular, the resource reuse configuration shown in Figure 6 indicates that all resources that are not included in any Coresets can be reused. For example, on partition 610, features 670 and 680, which have been shaded using different patterns of small dots, illustrate features that are not included in any Coresets. Each of the 670, 680 resources can be reused, as for the PDSCH or for other purposes. In addition, as shown in Figure 6, empty symbols within a Coreset or group of Coreset can be reused. Thus, in Figure 6, a scheme for using unused resources from the transmission may indicate that resources not allocated for any Coresets and / or
Petition 870190072920, of 07/30/2019, p. 42/102
38/57 Coreset groups (for example, resources 670, 680) can be reusable, and that resources associated with empty symbols within one or more Coreset groups (for example, resources 622, 632) are reusable.
[0073] In addition, Figure 6 illustrates that reusable resources can be configured to facilitate the use of narrowband by an UE. For example, resources 622, 632, 670 can be allocated for reuse by UE configured to monitor the first group of coreset (for example, the first Coreset 620 and the second coreset 630) and resources 680 can be allocated for reuse by UEs configured to monitor the second Coreset group (for example, the third Coreset 640 and the fourth Coreset 650). Such resource reuse configuration further facilitates the use of narrow band by UEs, locating reusable resources at frequencies close to the monitored frequencies for the configured group (the configured groups) of Coreset. In some scenarios or deployments, resources not included in any Coresets can be allocated unevenly. For example, part of the unused resources 680 is associated with the frequencies used by the second Coreset 630, although the reuse of such resources and frequencies is facilitated in symbols that are not used by the second Coreset 630. In modalities, one or more reuse fields resource can be used to indicate the configuration (the settings) of resource reuse for partition 610, as described above with reference to Figure 4. It is noted that the particular settings or schemes for resource reuse illustrated in Figures 4 to 6 are
Petition 870190072920, of 07/30/2019, p. 43/102
39/57 provided for the purpose of illustrating aspects of the use of Coreset groups, rather than limitation, and therefore should not be construed as limiting the present disclosure to the specific resource reuse configurations illustrated here.
[0074] As described above, for transmission schemes using carrier aggregation techniques, at least one Coreset group from one or more Coreset groups may comprise a primary Coreset transmitted through a first carrier and a secondary Coreset transmitted through a second carrier. In modalities, the primary Coreset can be transmitted on the first carrier by a service base station (for example, a service gNB) and the secondary Coreset can be transmitted on the second carrier by a second base station (for example, a neighboring gNB) . In addition, it is observed that in some modalities, a cell identifier for the primary Coreset and the secondary Coreset within a group of Coreset can be the same cell identifier, while in other modalities, the cell identifier for Coreset primary can be different from the cell identifier to the secondary Coreset (for example, when the primary and secondary Coresets are transmitted by
many different gNBs, for example). aspects of the modalities 0075 ] Using illustrated with reference to Figures 4 to 6, one gNB can to transmit control information (for example, DCI, CFI, etc.) to one HUH. In some modalities, the gNB can
transmit information associated with one or more Coresets corresponding to a neighboring cell to the UE, as described
Petition 870190072920, of 07/30/2019, p. 44/102
40/57 above. This can facilitate mitigation of interference between neighboring cells. As described above, information associated with one or more Coresets corresponding to a neighboring cell may comprise a list of primary (and possibly secondary) Coresets and Coreset configuration information for each identified Coreset in the list. A UE can receive the list and select one or more Coresets from the neighboring cell to monitor. The one or more Coresets from the neighboring cell can be selected based on whether they facilitate narrowband monitoring. For example, the UE can select a Coreset that is closest to the Coresets of the primary cell that serves the UE in terms of frequency, thus minimizing the frequency range monitored by the UE, resulting in less energy consumption by the UE. In other modalities, the primary cell can select Coreset (the Coresets) from the neighboring cell that is located closest to the Coresets configured for the UE (for example, Coresets of the primary cell), and communicate information associated with Coreset (the Coresets) identified (identified) by the primary cell for the UE. To facilitate this functionality, neighboring cells can share Coreset configuration information
with each other (for example, per middle of one link from backhaul communication, etc.). [0076] How illustrated in Figures 3 a 6, each Coreset can include a set of elements in resource.
For example, for each Coreset within a partition (for example, partition 310 in Figure 3, partition 410 in Figure 4, partition 510 in Figure 5, and partition 610 in Figure 6), the resource elements corresponding to subcarriers and
Petition 870190072920, of 07/30/2019, p. 45/102
41/57 symbols allocated to a Coreset can form a set of resources. In addition, where one or more Coresets are arranged in a group of Coreset, the resource elements allocated to those Coresets, or at least the resource elements allocated to data transmissions (for example, PDCCH data transmissions, PDSCH data transmissions etc.) form a group of resource pools. Thus, each Coreset can include a set of resources and a group of Coresets can include a group of resource sets.
[0077] With reference to Figure 7, a flow diagram that illustrates aspects of a method for configuring a transmission using groups of Coreset according to the modalities is shown as a 700 method. In modalities, the 700 method can be stored as instructions in a computer-readable medium. The instructions, when executed by one or more processors (for example, one or more of the gNBs 105 processors described and illustrated in relation to Figures 1 and 2), can cause the one or more processors to perform operations to configure a transmission using Coreset groups according to the modalities, as described above in relation to Figures 4 to 6, and as described in more detail below.
[0078] In 710, method 700 includes determining a plurality of Coresets and, in 720, grouping the plurality of Coresets into one or more Coreset groups. As described above in connection with Figures 4 to 6, each of the one or more Coreset groups can include a primary Coreset and zero or more secondary Coresets. It is observed that some modalities can establish a plurality of Coreset groups where a particular Coreset group does not include a
Petition 870190072920, of 07/30/2019, p. 46/102
42/57
Secondary Coreset, although other Coreset groups may include one or more secondary Coresets.
[0079] In modalities, grouping the plurality of Coresets into one or more Coreset groups, in 720, may also include, in 722, locating a primary Coreset and a secondary Coreset of a Coreset group in a transmission frequency domain. For example, when two Coreset groups are defined by the base station, each including a primary Coreset and a secondary Coreset, the primary Coreset and the secondary Coreset of the first Coreset group can be located in the transmission frequency domain, and Coreset primary and the secondary Coreset of the second group of Coreset can be in a different portion of the transmission frequency domain.
[0080] As explained above, locating the Coreset groups can facilitate the monitoring of narrowband transmissions (for example, transmissions from one or more base stations) by the UEs configured for a particular Coreset group. In addition, in modalities, for each of the one or more Coreset groups, the primary Coreset can provide a common search space and the secondary Coreset can provide a specific search space for the EU. As explained above, this can have the effect of sending an ordinary PDCCH. In some embodiments, method 700 may also include determining, by a base station, a resource reuse configuration for transmission. As explained here in relation to Figures 4 to 6 and 9, the resource reuse configuration can indicate a scheme to use unused resources from the transmission. The resource reuse setting can
Petition 870190072920, of 07/30/2019, p. 47/102
43/57 be communicated to the UE by a base station. For example, in modalities, the resource reuse configuration can be communicated to the UE using a resource reuse field (and one or more subfields) included in the control information (for example, DCI) transmitted by a base station, such as described above.
[0081] In modalities, the scheme for using unused resources from the transmission may indicate that resources that are not allocated to the one or more Coreset groups are reusable. For example, in Figure 4, reusable resources that are not assigned to the one or more Coreset groups can correspond to 470 resources. In modalities, the scheme for using unused resources from the transmission may still indicate that resources associated with empty symbols within one or more Coreset groups are reusable. For example, reusable resources associated with empty symbols within one or more Coreset groups may include resources 422, 432 in Figure 4, or resources 622, 632 in Figure 6. In some embodiments, resource reuse settings may determined separately for each group of Coreset. For example, a first group of Coreset may have a first scheme to use unused resources from the transmission and a second group of Coreset may have a second scheme to use unused resources from the transmission, where the first scheme and the second scheme are different. This is illustrated in Figure 6, where resources 622, 632 670 are available for reuse compared to UEs by monitoring the first group of Coreset that includes the first Coreset 620 and the
Petition 870190072920, of 07/30/2019, p. 48/102
44/57 according to Coreset 630, and resources 680 are available for reuse compared to UEs monitoring the second group of Coreset that includes the third Coreset 640 and the fourth Coreset 650. As explained above, this provides a narrow band configuration that allows narrowband monitoring and resource reuse by UEs configured for each Coreset group. It is noted that unused resources that are reusable can be used to transmit data to the UE using PDSCH.
[0082] In 730, method 700 includes configuring a UE to monitor one or more Coresets for at least one of the one or more Coreset groups for control information. For example, control information can include DCI, CFI information for each of the one or more Coreset groups, and other information. CFI information can indicate various symbols used to carry data for each of the Coreset groups. Depending on the particular configuration of the different Coreset groups, the CFI information may be the same for all Coreset groups, or may be different for each Coreset group (for example, a first group of Coreset can be associated with the first information CFI and a second group of Coreset can be associated with the second CFI information). For example, in some configurations, the number of symbols used to carry control data in each of the Coreset groups can be the same (for example, both a first group of Coreset and a second group of Coreset can carry information from control over the same number of symbols). In other Coreset group configurations, the number of
Petition 870190072920, of 07/30/2019, p. 49/102
45/57 symbols used to carry control data in each of the Coreset groups can be different (for example, a first group of Coreset can carry control information on a first number of symbols, such as a single symbol, and a second group of Coreset can carry control information about a different number of symbols, such as two symbols, as illustrated in Figures 4 to 6).
[0083] In modalities, a primary Coreset can have a predetermined configuration and the secondary Coreset (the secondary Coresets) can (can) have a dynamically configured transmission configuration. For example, the primary Coreset can be transmitted over a predetermined frequency range, and the secondary Coreset can have a dynamically determined configuration (for example, dynamic frequency range) depending on the number of specific UE transmissions and / or data to be Secondary Coreset are included.
[0084] In modalities, the primary Coreset can be transmitted on a first carrier and the secondary Coreset can be transmitted on a second carrier (for example, for carrier aggregation transmissions). As explained above, when carrier aggregation is used, the primary Coreset can be transmitted via a first carrier and the secondary Coreset can be transmitted via a second carrier via a service base station (for example, service gNB). In some modalities where carrier aggregation schemes are used, a primary Coreset can be transmitted via a first carrier through a service base station
Petition 870190072920, of 07/30/2019, p. 50/102
46/57 (for example, service gNB) and a secondary Coreset (or an additional primary Coreset) can be transmitted on a second carrier by a second base station (for example, a neighboring gNB), as described above. Depending on the number of gNBs that transmit Coresets, the cell identifier for the primary Coreset and the secondary Coreset can be the same, or different, as described above. As explained above, the service gNB (or possibly the neighboring gNB) can transmit information associated with one or more Coresets transmitted by the neighboring cell to the UE. In addition, in modalities, the service gNB can transmit information associated with the Coresets and Coreset groups provided by the service gNB to one or more neighboring gNBs, and can receive information indicating Coresets and Coreset groups provided by the neighboring gNB, such as described above.
[0085] In modalities, method 700 may include determining one or more Coresets corresponding to a neighboring cell, identifying a particular Coreset from the one or more Coresets corresponding to the neighboring cell, the particular Coreset corresponding to a Coreset to be monitored by the UE, and transmit, to the UE, information associated with the particular Coreset corresponding to the neighboring cell. This can facilitate the monitoring of narrowband of the particular Coreset of the neighboring cell by the UE, as described above. In particular, Coreset can be identified as a facilitator of narrowband monitoring by the UE. In some embodiments, instead of selecting the neighbor cell's Coreset for the UE, method 700 can cause gNB to transmit a list of Coresets (for example, Primary Coresets) from the neighboring cell to the UE, and the UE can then
Petition 870190072920, of 07/30/2019, p. 51/102
47/57 select the particular Coreset of the neighboring cell to be monitored based on the list and the Coresets configured for the UE by the service cell / gNB.
[0086] As shown above with reference to Figures 4 to 7, method 700 can allow monitoring of narrowband Coresets by a UE, resulting in reduced energy consumption by the UE. In addition, resource reuse settings can be used to provide efficient use of resources that are not used to provide control information within transmissions that comprise Coresets and Coreset groups. The improvements or enhancements mentioned above, provided by method 700, are described for purposes of illustration, and not as a limitation, and additional advantages that can be obtained by configuring transmissions using groups of Coresets and Coreset, according to method 700, can be readily apparent to a person skilled in the art.
[0087] With reference to Figure 8, a flow diagram that illustrates aspects of a method for receiving data from a transmission using Coreset groups according to the modalities is shown as an 800 method. In modalities, the 800 method can be stored as instructions in a computer-readable medium. The instructions, when executed by one or more processors (for example, one or more of the UE 115 processors described and illustrated in relation to Figures 1 and 2), can cause the one or more processors to perform operations to receive data from of a transmission using groups of Coreset according to the modalities, as described above in relation to Figures 4 to 6, and as described in more detail below.
Petition 870190072920, of 07/30/2019, p. 52/102
48/57 [0088] In 810, the method includes receiving, in one
EU, information identifying one or more groups in Coreset. In modalities, each one one or more groups in Coreset can include one Coreset primary and zero or more Coresets secondary. In some modalities, one group in Coreset can include one Coreset primary and at any less one Coreset secondary. In 820, the 800 method includes monitor at
UE, a transmission from a base station to detect at least one group of Coreset from one or more groups of Coreset. In modalities, the UE can be configured to monitor at least one group of Coreset included in a transmission having one or more groups of Coreset. For transmissions having at least two Coreset groups, the at least two Coreset groups can be transmitted over a broadband radio frequency, however, as explained above, the Coreset groups can be configured to allow the UE to perform monitoring through of a narrow band of radio frequencies, which can reduce the energy consumption of the UE, as described above in relation to Figures 4 to 7. In 830, method 800 includes, in response to the detection of at least one group of Coreset of the one or more Coreset groups, decode, by the UE, the information included in at least one Coreset group. In modalities, the UE can also receive configuration information for reusing resources that indicate a scheme for reusing transmission resources, as described here in relation to Figures 4 to 7 and 9.
[0089] In modalities where carrier aggregation is used for transmission, the transmission can be a multi-carrier transmission and the UE can monitor
Petition 870190072920, of 07/30/2019, p. 53/102
49/57 a first transmission carrier to detect a primary Coreset, and can monitor a second transmission carrier to detect a secondary Coreset. In embodiments, information provided through the primary Coreset can be transmitted by a first base station (for example, a service gNB), and information provided through the secondary Coreset can be transmitted by a second base station (for example, a neighboring gNB ).
[0090] As described above, the primary Coreset can provide a common search space and the secondary Coreset provide a specific search space for UE. In addition, as explained above, the data provided through the monitored Coreset group may include downlink grant information, uplink grant information, other types of control information, or a combination thereof. As explained above, monitoring groups of Coreset configured according to the modalities can facilitate the reduced energy consumption by the UE due to the location of the configured Coresets of the UE in the frequency domain. In addition, resource reuse settings can be used to provide efficient use of resources that are not used to provide control information within transmissions comprising Coresets and Coreset groups. The improvements or enhancements mentioned above, provided by the 800 method, are described for purposes of illustration, not as a limitation, and additional advantages that can be obtained by configuring transmissions using groups of Coresets and Coreset according to the 800 method can be readily readily available.

In modalities, the method 900 can be stored as instructions in a computer-readable medium. The instructions, when executed by one or more processors (for example, one or more of the gNB 105 processors described and illustrated in relation to Figures 1 and 2), can cause the one or more processors to perform operations to configure a configuration of resource reuse of a transmission that includes one or more control resource sets (Coresets) according to the modalities, as described above in relation to Figures 4 to 6, and as described in more detail below.

In embodiments, a particular Coreset group from one or more Coreset groups can be associated with a scheme to use unused resources from the transmission that indicates resources that are not assigned to the one or more Coreset groups are reusable and which resources associated with empty symbols within the particular Coreset group are reusable. In modalities, the one or more groups of Coreset can include at least a first group of Coreset and a second group of Coreset, where the first group of Coreset has a first scheme to use unused resources of the transmission and the second group of Coreset has a second scheme for using unused transmission resources, where the first scheme and the second scheme may be different.
