[0001] This application claims priority to U.S. Provisional Application Serial No. 63 / 716,805 filed on November 6, 2024, and entitled "Beam Reporting for STxMP with Asymmetric TRP," the entirety of which is incorporated by reference herein.Background
[0002] A user equipment (UE) may connect to a network via a base station. The base station may control multiple transmission and reception points (TRPs) . The UE may operate in multi-TRP (mTRP) mode where the UE establishes and maintains a connection with multiple TRPs at the same time.
[0003] In some scenarios, the mTRP operation may be asymmetric with respect to a UE . For example, there may be a scenario where the UE is communicating with two TRPs. The UE may have uplink (UL) communications with both TRPs but only downlink (DL) communications with one of the TRPs. This type of arrangement may be referred to as asymmetric TRP operation.
[0004] Multiple input multiple output (MIMO) operations may include simultaneous multi-panel transmission (STxMP) at the UE . This feature may provide benefits to the UE such as higher uplink throughput and reliability. It has been identified that there is a need for beam management mechanisms for STxMP with asymmetric TRP.Attorney Docket No. 30164 / 100402Ref. No. P69922W01Summary

[0012] The example embodiments may be further understood with reference to the following description and the related appended drawings, wherein like elements are provided with the same reference numerals. The example embodiments relate to beam management for simultaneous multi-panel transmission (STxMP) with asymmetric transmission reception point (TRP) .
[0013] The example embodiments are described with regard to a user equipment (UE) . However, reference to a UE is merely provided for illustrative purposes. The example embodiments may be utilized with any electronic component that may establish a connection to a network and is configured with the hardware, software, and / or firmware to exchange information and data with the network. Therefore, the UE as described herein is used to represent any appropriate type of electronic component.Attorney Docket No. 30164 / 100402Ref. No. P69922WO1
[0014] The example embodiments are also described with regard to a fifth generation (5G) New Radio (NR) network and a next generation node B (gNB) . However, reference to a 5G NR network and a gNB is merely provided for illustrative purposes. The example embodiments may be utilized with any appropriate type of network (e.g. , 5G Advanced, sixth generation (6G) , etc. ) and base station.
[0015] The gNB may be configured with multiple TRPs . Throughout this description, a TRP generally refers to a set of components configured to transmit and / or receive a beam. In some embodiments, multiple TRPs may be deployed locally at the gNB. For example, the gNB may include multiple antenna arrays / panels that are each configured to generate a different beam. In other embodiments, multiple TRPs may be deployed at various different locations and connected to the gNB via a backhaul connection. For example, multiple small cells may be deployed at different locations and connected to the gNB. However, these examples are merely provided for illustrative purposes. TRPs are configured to be adaptable to a wide variety of different conditions and deployment scenarios. Thus, any reference to a TRP being a particular network component or multiple TRPs being deployed in a particular arrangement is merely provided for illustrative purposes. The TRPs described herein may represent any type of network component configured to transmit and / or receive a beam.
[0016] The mTRP operation may be asymmetric with respect to the UE . For example, consider a scenario in which the UE is communicating with two TRPs. The UE may have uplink (UL) communications with both TRPs but only downlink (DL) communication with one of the TRPs. Throughout this description, asymmetric TRP operation may refer to a scenario in which the UEAttorney Docket No . 30164 / 100402Ref . No . P69922WO1 is configured with a single DL TRP and multiple UL TRPs or any other configuration in which the UE has a dif ferent number of DL and UL TRPs . However, reference to asymmetric TRP operation is merely provided for illustrative purposes . Di f ferent entities may refer to a similar concept by a different name .
[0001] MIMO operations may include STxMP at the UE which enables the UE to transmit simultaneously to multiple TRPs . STxMP may provide benefits to the UE such as higher uplink throughput and reliability . For beam management , one type of reporting mode is a j oint UL and DL reporting mode which may be used to configure a pair of beams that may be used to receive on the DL and transmit on the UL . Another type of reporting mode is UL only reporting mode which may be used to configure a pair of beams to be used to transmit simultaneously on the UL . Typically beam reporting is based on DL measurements . However, for STxMP with asymmetric TRP, there is no DL RS from the UL only TRP to use for beam management . It has been identified that there exists a need for beam management techniques to facilitate the implementation of STxMP with asymmetric TRP operation . The example embodiments introduce techniques for various dif ferent aspects of beam management for STxMP with asymmetric TRP . The example techniques introduced herein may be used independently from one another, in conj unction with other currently implemented beam management mechanisms , in conj unction with future implementations of beam management mechanisms or independently from other beam management mechanisms .
[0017] Fig . 1 shows an example network arrangement 100 according to various example embodiments . The example network arrangement 100 includes a UE 110 . The UE 110 may be any type of electronic component that is configured to communicate via aAttorney Docket No. 30164 / 100402Ref. No. P69922WO1 network, e.g. , mobile phones, tablet computers, desktop computers, smartphones, phablets, embedded devices, wearables, Internet of Things (loT) devices, etc. An actual network arrangement may include any number of UEs being used by any number of users. Thus, the example of a single UE 110 is merely provided for illustrative purposes.
[0018] The UE 110 may be configured to communicate with one or more networks. In the example of the network arrangement 100, the network with which the UE 110 may wirelessly communicate is a 5G NR radio access network (RAN) 120. However, the UE 110 may also communicate with other types of networks (e.g. , 6G RAN, 5G cloud RAN, a next generation RAN (NG-RAN) , a long-term evolution (LTE) RAN, a legacy cellular network, a wireless local area network (WLAN) , etc. ) and the UE 110 may also communicate with networks over a wired connection. With regard to the example embodiments, the UE 110 may establish a connection with the 5G NR RAN 120. Therefore, the UE 110 may have at least a 5G NR chipset to communicate with the 5G NR RAN 120.
[0019] The 5G NR RAN 120 may be a portion of a cellular network that may be deployed by a network carrier (e.g., Verizon, AT&T, T-Mobile, etc. ) . The 5G NR RAN 120 may include base stations or access nodes (Node Bs, eNodeBs, HeNBs, eNBS, gNBs, gNodeBs, macrocells, microcells, small cells, femtocells, etc. ) that are configured to send and receive traffic from UEs that are equipped with the appropriate cellular chip set.
[0020] In the network arrangement 100, the 5G NR RAN 120 deploys a gNB 120A. The gNB 120A may be configured with multiple TRPs. Each TRP may represent one or more components configured to transmit and / or receive a signal. In some embodiments,Attorney Docket No. 30164 / 100402Ref. No. P69922WO1 multiple TRPs may be deployed locally at the gNB 120A. In other embodiments, multiple TRPs may be distributed at different locations and connected to the gNB 120A via a backhaul connection. For example, multiple small cells may be deployed at different locations and connected to the gNB 120A. However, these examples are merely provided for illustrative purposes. TRPs are configured to be adaptable to a wide variety of different conditions and deployment scenarios. Thus, any reference to a TRP being a particular network component or multiple TRPs being deployed in a particular arrangement is merely provided for illustrative purposes. The TRPs described herein may represent any type of network component configured to transmit and / or receive a beam.
[0021] Any association procedure may be performed for the UE 110 to connect to the 5G NR RAN 120. For example, as discussed above, the 5G NR RAN 120 may be associated with a particular cellular provider where the UE 110 and / or the user thereof has a contract and credential information (e.g. , stored on a SIM card) . Upon detecting the presence of the 5G NR RAN 120, the UE 110 may transmit the corresponding credential information to associate with the 5G NR RAN 120. More specifically, the UE 110 may associate with a specific base station, e.g., the gNB 120A.
[0022] The network arrangement 100 also includes a cellular core network 130, the Internet 140, an IP Multimedia Subsystem (IMS) 150, and a network services backbone 160. The cellular core network 130 may refer to an interconnected set of components that manages the operation and traffic of the cellular network. It may include the evolved packet core (EPC) and / or the 5G core (5GC) . The cellular core network 130 alsoAttorney Docket No. 30164 / 100402Ref. No. P69922WO1 manages the traffic that flows between the cellular network and the Internet 140. The IMS 150 may be generally described as an architecture for delivering multimedia services to the UE 110 using the IP protocol. The IMS 150 may communicate with the cellular core network 130 and the Internet 140 to provide the multimedia services to the UE 110. The network services backbone 160 is in communication either directly or indirectly with the Internet 140 and the cellular core network 130. The network services backbone 160 may be generally described as a set of components (e.g., servers, network storage arrangements, etc.) that implement a suite of services that may be used to extend the functionalities of the UE 110 in communication with the various networks .
[0023] Fig. 2 shows an example UE 110 according to various example embodiments. The UE 110 will be described with regard to the network arrangement 100 of Fig. 1. The UE 110 may include a processor 205, a memory arrangement 210, a display device 215, an input / output (I / O) device 220, a transceiver 225 and other components 230.

[0024] The processor 205 may be configured to execute a plurality of engines of the UE 110. For example, the engines may include a beam management for STxMP engine 235 that may perform various operations related to beam management for STxMP with asymmetric TRP .Attorney Docket No. 30164 / 100402Ref. No. P69922WO1
[0025] The above referenced engine 235 being applications (e.g., a program) executed by the processor 205 is merely provided for illustrative purposes. The functionality associated with the engine 235 may also be represented as a separate incorporated component of the UE 110 or may be a modular component coupled to the UE 110, e.g., an integrated circuit with or without firmware. For example, the integrated circuit may include input circuitry to receive signals and processing circuitry to process the signals and other information. The engine may also be embodied as one application or separate applications. In addition, in some UEs, the functionality described for the processor 205 is split among two or more processors such as a baseband processor and an applications processor. The example embodiments may be implemented in any of these or other configurations of a UE .
[0026] The memory arrangement 210 may be a hardware component configured to store data related to operations performed by the UE 110. The display device 215 may be a hardware component configured to show data to a user while the I / O device 220 may be a hardware component that enables the user to enter inputs. The display device 215 and the I / O device 220 may be separate components or integrated together such as a touchscreen .
[0027] The transceiver 225 may be a hardware component configured to establish a connection with the 5G NR-RAN 120, an LTE-RAN (not pictured) , a legacy RAN (not pictured) , a WLAN (not pictured) , etc. Accordingly, the transceiver 225 may operate on a variety of different frequencies or channels (e.g. , set of consecutive frequencies) . The transceiver 225 includes circuitry configured to transmit and / or receive signals (e.g. , controlAttorney Docket No. 30164 / 100402Ref. No. P69922W01 signals, data signals) . Such signals may be encoded with information implementing any one of the methods described herein. The processor 205 may be operably coupled to the transceiver 225 and configured to receive from and / or transmit signals to the transceiver 225. The processor 205 may be configured to encode, decode and / or process signals (e.g. , signaling from a base station of a network) for implementing any one of the methods described herein.
[0028] In the example of Fig. 2, the processor 205 and the radio frequency (RF) circuitry (e.g. , transceiver 225) are illustrated as separate components. However, in some example embodiments, the RF circuitry and the processing circuitry may be integrated into the same chip, e.g., a system on chip that includes a baseband processor and RF circuitry.
[0029] Fig. 3 shows an example base station 300 according to various example embodiments. The base station 300 may represent the gNB 120A or any other type of access node through which the UE 110 may establish a connection and manage network operations .
[0030] The base station 300 may include a processor 305, a memory arrangement 310, an input / output (I / O) device 315, a transceiver 320, multiple TRPs 330 and other components 325. The other components 325 may include, for example, an audio input device, an audio output device, a battery, a data acquisition device, ports to electrically connect the base station 300 to other electronic devices and / or power sources, transceiver chains, antenna elements, antenna panels, etc.Attorney Docket No. 30164 / 100402Ref. No. P69922WO1
[0031] As indicated above, in some scenarios, the multiple TRPs 330 may be deployed locally at the base station 300. In other scenarios, one or more of the multiple TRPs 330 may be deployed at physical locations remote from the base station 300 and connected to the base station via a backhaul connection. The base station 300 may be configured to control the multiple TRPs 330 and perform operations such as, but not limited to, assigning resources, configuring reference signals, implementing beam management techniques, etc.
[0032] The processor 305 may be configured to execute a plurality of engines for the base station 300. For example, the engines may include a beam management for STxMP engine 335 that may perform various operations related to beam management for STxMP with asymmetric TRP .
[0033] The above noted engine 335 being an application (e.g. , a program) executed by the processor 305 is only an example. The functionality associated with the engine 335 may also be represented as a separate incorporated component of the base station 300 or may be a modular component coupled to the base station 300, e.g. , an integrated circuit with or without firmware. For example, the integrated circuit may include input circuitry to receive signals and processing circuitry to process the signals and other information. In addition, in some base stations, the functionality described for the processor 305 is split among a plurality of processors (e.g., a baseband processor, an applications processor, etc. ) . The example embodiments may be implemented in any of these or other configurations of a base station.Attorney Docket No. 30164 / 100402Ref. No. P69922WO1
[0034] The memory arrangement 310 may be a hardware component configured to store data related to operations performed by the base station 300. The I / O device 315 may be a hardware component or ports that enable a user to interact with the base station 300.
[0035] The transceiver 320 may be a hardware component configured to exchange data with the UE 110 and any other UEs in the network arrangement 100. The transceiver 320 may operate on a variety of different frequencies or channels (e.g. , set of consecutive frequencies) . Therefore, the transceiver 320 may include one or more components to enable the data exchange with the various networks and UEs. The transceiver 320 includes circuitry configured to transmit and / or receive signals (e.g., control signals, data signals) . Such signals may be encoded with information implementing any one of the methods described herein. The processor 305 may be operably coupled to the transceiver 320 and configured to receive from and / or transmit signals to the transceiver 320. The processor 305 may be configured to encode, decode and / or signals (e.g., signaling from a UE) for implementing any one of the methods described herein .
[0036] In the example of Fig. 3, the processor 305 and the radio frequency (RF) circuitry (e.g. , transceiver 320) are illustrated as separate components. However, in some example embodiments, the RF circuitry and the processing circuitry may be integrated into the same chip, e.g., a system on chip that includes a baseband processor and RF circuitry.
[0037] Fig. 4 shows an example system arrangement 400 where a UE 110 is communicating with an asymmetric TRP arrangementAttorney Docket No. 30164 / 100402Ref. No. P69922WO1 according to various example embodiments. In the example of Fig. 4, the UE 110 is communicating with a first TRP 410 and a second TRP 420. The UE 110 may communicate in both the DL and UL with the TRP 410. However, the UE 110 may only communicate in the UL with the TRP 420. The TRPs 410 and 420 may be associated with a base station (e.g., base station 300) that may be a serving cell for the UE 110 in this scenario.
[0038] Fig. 5 shows an example method 500 for beam management according to various example embodiments. The method 500 is described with regard to the UE 110 and the asymmetric TRP arrangement shown in Fig. 4. The method 500 is provided as a general overview for beam management and to provide context for the example techniques introduced herein. The example embodiments are not limited to the beam management procedures described in the method 500 and may be utilized in any appropriate beam management procedure.
[0039] In 510, the UE 110 receives beam management configuration information from a base station of a network for STxMP with asymmetric TRP. For example, the base station may control multiple TRPs (e.g., TRP 410 and 420) of an asymmetric TRP arrangement.
[0040] The beam management configuration information may be provided in one or more radio resource control (RRC) messages, downlink control information (DCI) , medium access control (MAC) control elements (CEs) , any combination thereof or in any other appropriate type of message.
[0041] To provide some non-limiting examples, the beam management configuration information may include configuration information for resources sets that are to be used for beamAttorney Docket No. 30164 / 100402Ref. No. P69922WO1 measurements, conditions to trigger beam reporting and an indication of the type of parameters and values that are to be reported for beam management. As will be described in more detail below, the example embodiments introduce techniques for sounding reference signal (SRS) based beam selection.Accordingly, the beam management configuration information may include configuration information for SRS that is to be used for beam management. These and other example embodiments are described in greater detail below after the description of the method 500.
[0042] In 515, the UE 110 transmits SRS to the base station. As will be described in greater detail below, the SRS may be used by the network to configure UL beams that are to be used by the UE 110 for STxMP RUSCH transmissions.
[0043] In 520, the UE 110 receives beam measurement resources. For example, the UE 110 may be configured with one or more channel measurement resource (CMR) resource sets that are to be used for beam measurement. The CMR resource set may include synchronization signal block (SSB) , channel state information (CSI ) -reference signal (RS) and / or any other appropriate type of measurement resource.
[0044] In 525, the UE 110 transmits one or more CSI reports to the base station. The one or more CSI reports may be based on the one or more CMR resource sets and include beam measurements for one or more beams (e.g., beam reporting) . The CSI reports may include layer 1 (LI ) -ref erence signal received power (RSRP) measurements or any other appropriate type of information that may indicate to the network which beams are to be used by the UE 110 for subsequent UL and / or DL communication.Attorney Docket No. 30164 / 100402 Ref. No. P69922WO1
[0045] In 530, the network selects an UL beam pair to be used by the UE 110. The network may select the beams based on the CSI reports provided by the UE 110, the SRS transmitted by the UE 110 and / or any other appropriate factor. The example embodiments introduce beam management techniques for UL transmissions by a UE configured for STxMP in an asymmetric TRP arrangement. Therefore, the method 500 is described from the perspective of beam management for UL communication. However, the signaling between the UE 110 and the network may also include beam related information for DL communication.
[0046] In 535, the UE 110 receives scheduling information for a PUSCH transmission. In 540, the UE 110 performs the PUSCH transmission. The PUSCH transmission may be a simultaneous PUSCH transmission to multiple UL TRPs in the asymmetric TRP arrangement .
[0047] According to one aspect, the example embodiments introduce an SRS resource set based beam selection for STxMP with asymmetric TRP. This example embodiment will be described with regard to the method 500 of Fig. 5.
[0048] For SRS resource set based beam selection, the network may configure the UE 110 with two SRS resource sets. The SRS resource set configuration information may be provided to the UE 110 in one or more information elements (IES) . For example, the beam management configuration information in 510 may include one or more SRS-ResourceSet IEs.
[0049] An SRS resource set IE may include a usage parameter that may be set to one of beam management, codebook, noncodebook or any other appropriate enumerated value. In this example, each SRS resource set IE may set a usage parameter to aAttorney Docket No. 30164 / 100402Ref. No. P69922WO1 value of beam management.
[0050] For SRS resource set based beam selection, each SRS Resource set IE may not configure spatial relation information or transmission configuration indication (TCI) state information for the SRS resources of the SRS resource set. Instead, the UE 110 may perform a beam sweep when transmitting the SRS resources. For example, in 515, the UE 110 may use different spatial filters for simultaneous transmission when transmitting SRS from different resource sets. The resources from the different SRS resource sets may or may not be overlapping in time .
[0051] On the network side, the base station may collect measurement data corresponding to the SRS transmitted by the UE 110. The base station may then decide, based at least in part on the SRS, a pair of SRS to be used for the UL TCI state configuration for simultaneous transmission of PUSCH. The network may select one SRS from a first SRS resource set and one SRS from a second SRS resource set which can be transmitted with different spatial filters simultaneously for PUSCH TCI state. The network may provide this information to the UE 110 and the UE 110 may use this configuration to perform the simultaneous PUSCH transmission.
[0052] According to one aspect, the example embodiments introduce an SRS based beam selection for STxMP with asymmetric TRP . This example embodiment will be described with regard to the method 500 of Fig. 5.
[0053] For SRS based beam selection, the network may configure the UE 110 with two SRS resource sets and one DL RS based resource set. The SRS resource set configurationAttorney Docket No. 30164 / 100402Ref. No. P69922WO1 information and the DL RS resource set configuration information may be provided to the UE 110 in one or more IES . For example, the beam management configuration information in 510 may include one or more SRS resource set IEs and one or more CMR resource set IEs.
[0054] A first SRS resource set may have a usage parameter set to beam management. In addition, the first SRS resource set may not have spatial relation information and / or TCI state configuration information configured for the SRS resources of the first SRS resource set. The UE 110 may select the spatial filter to use for the SRS transmission. This may include performing a beam sweep.
[0055] The DL RS resource set may be configured for beam reporting. For example, in 520, the UE 110 may receive CMR identified in the DL RS resource set and in 525, the UE 110 may transmit a CSI report including measurement information based on the CMR identified in the DL RS resource set. The CMR resources may be SSB, CSI-RS or a combination thereof.
[0056] A second SRS resource set may have a usage parameter set to codebook or non-codebook. In addition, the spatial relation information and / or TCI state configuration information for the SRS may be set to the CMR from the DL RS resource set.
[0057] The UE 110 may use different spatial filters for reception of the CMR and transmission of SRS corresponding to the second SRS resource set. In addition, the UE 110 may also use different spatial filters for the transmission of SRS from the first SRS resource set which may be used for simultaneous IL transmission .Attorney Docket No . 30164 / 100402Ref . No . P69922WO1
[0058] On the network side , the base station may collect measurement data corresponding to the SRS transmitted by the UE 110 . The base station may then decide , based at least in part on the SRS , a pair of SRS to be used for the UL TCI state configuration for simultaneous transmission of PUSCH . The network may select one SRS from the first SRS resource set and one SRS from the second SRS resource set which can be transmitted with di f ferent spatial filters simultaneously for PUSCH TCI state . The network may provide this information to the UE 110 and the UE 110 may use this configuration to perform the simultaneous PUSCH transmission .
[0059] According to another aspect , the example embodiments introduce a DL RS and SRS based beam selection for STxMP with asymmetric TRP . This example embodiment will be described with regard to the method 500 of Fig . 5.
[0060] For DL RS and SRS based beam selection, the network may configure the UE 110 with one SRS resource set and one DL RS based resource set . The SRS resource set configuration information and the DL RS resource set configuration information may be provided to the UE 110 in one or more IE S . For example, the beam management configuration information in 510 may include one or more SRS resource set IEs and one or more CMR resource set IEs .
[0061] The SRS resource set may have a usage parameter set to beam management . In addition, the SRS resource set may not have spatial relation information and / or TCI state configuration information configured for the SRS resources in the SRS resource set . The UE 110 may select a spatial filter for the SRS transmission . This may include performing a beam sweep .Attorney Docket No. 30164 / 100402Ref. No. P69922WO1
[0062] The DL RS resource set may be configured for beam reporting. For example, in 520, the UE 110 may receive CMR identified in the DL RS resource set and in 525, the UE 110 may transmit a CSI report including measurement information based on the CMR identified in the DL RS resource set. The CMR resources may be SSB, CSI-RS or a combination thereof.
[0063] The UE 110 may use different spatial filers for reception of the CMR from the DL RS resource set and transmission of the SRS from the SRS resource set which can be used for simultaneous UL transmission.
[0064] On the network side, the base station collects measurement data corresponding to the SRS. The base station may then consider the measurement data from the CSI reports (e.g., Ll-RSRP, etc.) and measurement data corresponding to the SRS when selecting a pair of SRS to be used for the UL TCI state configuration for simultaneous transmission of PUSCH. The network may select one SRS from the SRS resource set and one DL RS from the second SRS resource set which can be transmitted with different spatial filters simultaneously for PUSCH TCI state. The network may provide this information to the UE 110 and the UE 110 may use this configuration to perform the simultaneous PUSCH transmission.Examples
