[0002] CROSS-REFERENCE TO RELATED APPLICATIONS

[0003] This application claims priority to U.S. Provisional Patent Application No. 62 / 846,469, filed on May 10, 2019, entitled “SIGNALING USER EQUIPMENT MULTI-PANEL CAPABILITY,” and U.S. Non-Provisional Patent Application No. 16 / 869,313, filed on May 7, 2020, entitled “SIGNALING USER EQUIPMENT MULTI-PANEL CAPABILITY,” which are hereby expressly incorporated herein by reference.

[0004] Public domain

[0005] Aspects of the present disclosure generally relate to wireless communications and techniques and apparatus for signaling user equipment (UE) multi-panel capabilities.

[0006] background

[0007] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0008] A wireless communication network may include several base stations (BS) that can support communication of several user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. Downlinks (or forward links) refer to the communication link from a BS to a UE, while uplinks (or reverse links) refer to the communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an Access Point (AP), a Radio Head, a Transmit Receive Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.

[0009] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocols that enable different user equipment to communicate at city, country, region, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to better integrate with other open standards. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that employ these technologies.

[0028] Detailed Description

[0029] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0030] 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 following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0031] It should be noted that although various aspects may be described herein using terminology typically associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied in communication systems based on other generations, such as 5G and later generations, including NR technologies.

[0032] Figure 1 1 is a diagram illustrating a wireless network 100 in which various aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include several BSs 110 (shown as BSs 110a, BSs 110b, BSs 110c, and BSs 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NRBS, B node, gNB, 5G B node (NB), access point, transmit receive point (TRP), and the like. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0033] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" may be used interchangeably herein.

[0034] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces, such as direct physical connections, virtual networks, and / or the like using any suitable transport network.

[0035] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , a relay station 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0036] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0037] A network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0038] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0039] Some UEs may be considered as machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as client equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component, a memory component, and the like.

[0040] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific RAT and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0041] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0042] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 Examples described.

[0043] Figure 2 A block diagram of a design 200 of a base station 110 and a UE 120 is shown, which may be Figure 1 One for each base station and one for each UE in the base station 110. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≧1 and R≧1.

[0044] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to convey additional information.

[0045] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0046] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from the UE 120 as well as other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and provide decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0047] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component(s) of the base station 110 may perform one or more techniques associated with signaling a user equipment (UE) multi-panel capability, as described in greater detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) may perform or direct e.g. Figure 4 The process of 400 Figure 5 The operations of process 500, and / or other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. Scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0048] In some aspects, UE 120 may include: means for identifying one or more multi-panel capabilities for multi-panel operation of multiple panels associated with UE 120; means for transmitting an indication of the one or more multi-panel capabilities to base station 110, etc. In some aspects, such means may include in conjunction with Figure 2 One or more components of UE 120 are described.

[0049] In some aspects, base station 110 may include: means for receiving from UE 120 an indication of one or more multi-panel capabilities for multi-panel operation of multiple panels associated with UE 120; means for transmitting to UE 120 a scheduling configuration for multi-panel operation of the multiple panels based at least in part on the one or more multi-panel capabilities, etc. In some aspects, such means may include in conjunction with Figure 2 One or more components of base station 110 are described.

[0050] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.

[0051] In some cases, the UE may be a multi-panel device capable of communicating with a BS using millimeter wave (mmWave) transmissions (e.g., using frequencies above 24 GHz). In this case, the UE may be equipped with multiple panels including multiple antenna assemblies (e.g., 16 antenna assemblies, 32 antenna assemblies, etc.). For the purpose of multi-panel operation, the panel may include antenna assemblies that can independently control transmit beams relative to other panels, can independently control transmit power relative to other panels, have common uplink transmission timing, etc. Although the UE is able to use multiple panels for transmit diversity, uplink coverage enhancement, MIMO, increased throughput, etc., the BS communicating with the UE may not be aware of the UE's multi-panel capabilities. As a result, the BS may not be able to schedule communications with the UE in a manner that does not fully utilize the UE's multi-panel capabilities.

[0052] Some aspects described herein provide techniques and apparatus for signaling UE multi-panel capabilities. In some aspects, a multi-panel UE may transmit an indication of one or more multi-panel capabilities for multi-panel operation to a BS. The BS may receive an indication of one or more multi-panel capabilities and may transmit a scheduling configuration generated at least in part based on the indication of one or more multi-panel capabilities to the UE. In this way, the scheduling configuration may utilize the multi-panel capabilities of the UE so that the UE may use the multi-panel operation for transmit diversity, uplink coverage enhancement, MIMIO, increased throughput, etc.

[0053] Figure 3 is a diagram illustrating an example 300 of signaling UE multi-panel capabilities according to various aspects of the present disclosure. Figure 3 As shown in , example 300 may include communication between a UE (e.g., UE 120) and a BS (e.g., BS 110). The UE may be a multi-panel device including multiple panels (e.g., antenna panels). The UE may communicate with the BS and / or other communication devices in a multi-panel operation using multiple panels.

[0054] like Figure 3 In the embodiment and indicated by reference numeral 302, to enable multi-panel operation at a UE, the UE may identify one or more multi-panel capabilities for multi-panel operation of a plurality of panels included in the UE.

[0055] The one or more multi-panel capabilities may include a total number of multiple panels included in the UE. In addition, the UE may indicate corresponding identifiers associated with the multiple panels. The corresponding identifiers may include a panel identifier based at least in part on a sounding reference signal (SRS) resource set identifier, an identifier associated with a reference signal resource or resource set, an identifier assigned to a target reference signal resource or resource set, an identifier configured at least in part based on a spatial relationship, and the like. In some aspects, the UE may indicate one or more corresponding measurements associated with the multiple panels, which may include a signal to interference plus noise ratio (SINR), a transmit power measurement, and the like.

[0056] The one or more multi-panel capabilities may include the number of active panels supported by the UE. The number of active panels may be based at least in part on an operating state of the UE (e.g., whether the UE is in an active or connected state, an idle state, an inactive state, etc.), may be based at least in part on a battery level of the UE (e.g., the greater the battery level of the UE, the greater the number of panels that the UE may activate), etc.

[0057] One or more multi-panel capabilities may include a time duration for switching between active panels scheduled for consecutive transmissions. For example, in some cases, the UE may not be able to transmit simultaneously using multiple active panels in multi-panel operation, but may cycle between active panels for transmit diversity or increased uplink coverage. Accordingly, the time duration for switching between active panels may indicate the amount of time it takes for the UE to terminate a first transmission on a first active panel and initiate a second transmission on a second active panel.

[0058] The one or more multi-panel capabilities may include a respective number of spatial layers supported by each of the plurality of panels (e.g., the number of spatial layers on which the panel is capable of transmitting simultaneously). The one or more multi-panel capabilities may include a respective number of beams supported by each of the plurality of panels (e.g., the number of beams on which the panel is capable of transmitting simultaneously). The one or more multi-panel capabilities may include a respective activation time for each of the plurality of panels. The activation time may indicate an amount of time for a particular panel to activate an associated radio frequency (RF) chain and / or another transmission component to enable the panel to perform a transmission.

[0059] The one or more multi-panel capabilities may include an indication of panels in a plurality of panels that may be grouped together to share the same power control parameters (e.g., transmit power parameters, path loss parameters, etc.), the same timing alignment, the same activation state (e.g., panels in a group may be activated and / or deactivated together), etc. In some aspects, the one or more multi-panel capabilities may include one or more of the multi-panel capabilities described above and / or other multi-panel capabilities.

[0060] As in Figure 33 and further indicated by reference numeral 304, the UE may transmit an indication of one or more multi-panel capabilities to the BS. The UE may transmit the indication of the one or more multi-panel capabilities in one or more communications, which may include one or more radio resource control (RRC) communications, one or more uplink control information (UCI) communications, etc. In some aspects, the UE may transmit the one or more communications based at least in part on receiving a request for indication of the one or more multi-panel capabilities (e.g., from the BS), may transmit the one or more communications based at least in part on being communicatively connected with the BS (e.g., as part of a connection establishment process), may transmit the one or more communications on a periodic basis, etc.

[0061] In some aspects, after the UE transmits an indication of one or more multi-panel capabilities to the BS, the UE may transmit an indication of an update of the UE's multi-panel capabilities to the BS so that the BS may adjust a scheduling configuration for the UE. For example, the UE may transition to an idle state, and the UE may transmit (e.g., before the transition) an indication of an updated number of active panels supported by the UE as a result of the UE transitioning to the idle state.

[0062] If further Figure 3 In the embodiment and indicated by reference numeral 306, the BS may receive an indication of one or more multi-panel capabilities and may generate and transmit a scheduling configuration to the UE. In some aspects, the BS may transmit the indication of the scheduling configuration in one or more communications (such as, one or more RRC communications, one or more media access control (MAC) control element (MAC-CE) communications, one or more downlink control information (DCI) communications, etc.).

[0063] The scheduling configuration may be generated based at least in part on one or more multi-panel capabilities of the UE. For example, the BS may identify one or more requested panels to be used for communication with the BS based at least in part on an indication of the number of panels. In this case, the BS may identify the one or more requested panels based at least in part on one or more measurements associated with the one or more requested panels.
