Technical Field

[0002]

[0002] Aspects of the present disclosure generally relate to wireless communication and, more particularly, to techniques for multiplexing channel state information reports in multiple transmit - receive point (TRP) scenarios.

Background Art

[0003]

[0003] Wireless communication systems are widely deployed to provide various telecommunications services such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ a multiple access technology 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 (registered trademark)). LTE / LTE-Advanced is a set of extensions to the Universal Mobile Telecommunications System (UMTS) mobile standard published by the Third Generation Partnership Project (3GPP (registered trademark)).

[0004]

[0004] A wireless communication network may include several base stations (BSs) that can support communication for several user equipments (UEs). The user equipment (UE) may communicate with the base station (BS) via the downlink (DL) and the uplink (UL). The DL (or forward link) refers to the communication link from the BS to the UE, and the UL (or reverse link) refers to the communication link from the UE to the BS. As described in more detail herein, the BS may be referred to, among other examples, as Node B, LTE evolved Node B (eNB), gNB, access point (AP), radio head, transmit receive point (TRP), New Radio (NR) BS, or 5G Node B.

[0005]

[0005] The above-mentioned multi-connectivity technology is adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a city, national, regional, and even global scale. NR, sometimes referred to as 5G, is a set of extensions to the LTE mobile standard published by the 3rd Generation Partnership Project (3GPP). NR is designed to better support mobile broadband internet access by improving spectral efficiency, reducing costs, improving services, utilizing new spectra, and better integrating with other open standards by using orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) (CP-OFDM) on the DL and using CP-OFDM or single-carrier frequency division multiplexing (SC-FDM), also known as discrete Fourier transform spread OFDM (DFT-s-OFDM), on the UL (or combinations thereof), as well as by supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation.

Summary of the Invention

[0006]

[0006] The systems, methods, and devices of the present disclosure each have several inventive aspects, and no single one of them alone bears the desirable attributes disclosed herein.

[0007] One inventive aspect of the subject matter described in this disclosure may be implemented in a method of wireless communication performed by an apparatus of a user equipment (UE). The method includes receiving at least one configuration for identifying resources for multiplexing channel state information (CSI) reports that may collide within a slot; determining that a plurality of CSI reports, a first set of CSI reports to be transmitted to a first transmission and reception point (TRP) or a second set of CSI reports to be transmitted to a second TRP, may collide within the slot; and transmitting at least one of the first set of CSI reports to the first TRP or the second set of CSI reports to the second TRP according to the at least one configuration, where the first set of CSI reports or the second set of CSI reports are multiplexed in the resources.

[0008] In some implementations, the at least one configuration identifies a plurality of resources, and the method may further include selecting resources for multiplexing the CSI reports based on the payload size of the first set of CSI reports or the second set of CSI reports.

[0009] In some implementations, determining that a plurality of CSI reports may collide within a slot includes determining that a first CSI report and a second CSI report are scheduled in overlapping resources within the slot.

[0010] In some implementations, the method may further include determining a first association between the first set of CSI reports and the first TRP and a second association between the second set of CSI reports and the second TRP.

[0011]

[0011] In some implementations, the first association and the second association are determined based on at least one of: a first other configuration that identifies a first resource for transmitting a CSI report as being associated with a first TRP, and a second other configuration that identifies a second resource for transmitting a CSI report as being associated with a second TRP; or another configuration that identifies a first CSI reporting configuration as being associated with a first TRP and a second CSI reporting configuration as being associated with a second TRP.

[0012]

[0012] In some implementations, the method may further include identifying a non-ideal backhaul condition between the first TRP and the second TRP before transmitting at least one of a first set of CSI reports or a second set of CSI reports.

[0013]

[0013] In some implementations, the non-ideal backhaul condition is identified based on at least one of: another configuration indicating a non-ideal backhaul condition; another configuration identifying different hybrid automatic repeat request (HARQ) acknowledgement reports for the first TRP and the second TRP; a first other configuration that identifies a first resource for transmitting a CSI report as being associated with a first TRP, and a second other configuration that identifies a second resource for transmitting a CSI report as being associated with a second TRP; or another configuration that identifies a first CSI reporting configuration as being associated with a first TRP and a second CSI reporting configuration as being associated with a second TRP.

[0014]

[0014] In some implementations, the first set of CSI reports and the second set of CSI reports are transmitted in separate resources.

[0015]

[0015] In some implementations, the second set of CSI reports is a subset of non - colliding CSI reports among a set of CSI reports having a plurality of CSI reports that may collide within a slot.

[0016]

[0016] In some implementations, the second set of CSI reports includes one or more CSI reports selected from a set of CSI reports having a plurality of CSI reports that may collide within a slot according to one or more prioritization criteria.

[0017]

[0017] In some implementations, distinct resources do not overlap.

[0018]

[0018] In some implementations, receiving at least one configuration includes receiving a first configuration that identifies a first resource for multiplexing CSI reports and receiving a second configuration that identifies a second resource for multiplexing CSI reports, where the first set of CSI reports is multiplexed on the first resource and transmitted to a first TRP, and the second set of CSI reports is multiplexed on the second resource and transmitted to a second TRP.

[0019]

[0019] In some implementations, the second configuration further identifies a third resource for multiplexing CSI reports, and the method may further include selecting the second resource for transmitting the second set of CSI reports based on a determination that the third resource overlaps with the first resource within a slot and the second resource does not overlap with the first resource within the slot.

[0020]

[0020] In some implementations, at least one component is a single component that identifies a first resource for multiplexing CSI reports to be sent to a first TRP and a second resource for multiplexing CSI reports to be sent to a second TRP, a first set of CSI reports being multiplexed in the first resource and sent to the first TRP, and a second set of CSI reports being multiplexed in the second resource and sent to the second TRP.

[0021]

[0021] Another inventive aspect of the subject matter described in this disclosure may be implemented in a UE device for wireless communication. The device may include a first interface configured to obtain at least one component that identifies a resource for multiplexing CSI reports that may collide during a slot. The device may include a processing system configured to determine that a plurality of CSI reports of a first set of CSI reports to be sent to a first TRP or a second set of CSI reports to be sent to a second TRP have a possibility of colliding during a slot. The device may include a second interface configured to output at least one of a first set of CSI reports to the first TRP or a second set of CSI reports to the second TRP according to at least one component, where the first set of CSI reports or the second set of CSI reports are multiplexed in a resource.

[0022]

[0022] In some implementations, at least one component identifies a plurality of resources, and the processing system is further configured to select a resource for multiplexing CSI reports based on the payload size of the first set of CSI reports or the second set of CSI reports.

[0023]

[0023] In some implementations, when the processing system determines that a plurality of CSI reports have a possibility of colliding during a slot, it is configured to determine that a first CSI report and a second CSI report are scheduled in overlapping resources during the slot.

[0024]

[0024] In some implementations, the processing system is further configured to determine a first association between a first set of CSI reports and a first TRP, and a second association between a second set of CSI reports and a second TRP.

[0025]

[0025] In some implementations, the first association and the second association are a first other configuration that identifies a first resource for transmitting CSI reports as being associated with the first TRP, and a second other configuration that identifies a second resource for transmitting CSI reports as being associated with the second TRP; or another configuration that identifies a first CSI report configuration as being associated with the first TRP and a second CSI report configuration as being associated with the second TRP, and is determined based on at least one of them.

[0026]

[0026] In some implementations, the processing system is further configured to identify a non-ideal backhaul state between the first TRP and the second TRP before outputting at least one of the first set of CSI reports or the second set of CSI reports.

[0027]

[0027] In some implementations, the non-ideal backhaul state is identified based on at least one of another configuration indicating the non-ideal backhaul state; another configuration identifying different HARQ acknowledgment reports for the first TRP and the second TRP; a first other configuration that identifies a first resource for transmitting CSI reports as being associated with the first TRP, and a second other configuration that identifies a second resource for transmitting CSI reports as being associated with the second TRP; or another configuration that identifies a first CSI report configuration as being associated with the first TRP and a second CSI report configuration as being associated with the second TRP.

[0028]

[0028] In some implementations, the first set of CSI reports and the second set of CSI reports are output in separate resources.

[0029]

[0029] In some implementations, the second set of CSI reports is a subset of non - colliding CSI reports among a set of CSI reports having a plurality of CSI reports that may collide during a slot.

[0030]

[0031]

[0031] In some implementations, the separate resources do not overlap.

[0032]

[0032] In some implementations, when obtaining at least one configuration, the processing system is configured to obtain a first configuration that identifies a first resource for multiplexing CSI reports and a second configuration that identifies a second resource for multiplexing CSI reports. The first set of CSI reports is multiplexed in the first resource and output for the first TRP, and the second set of CSI reports is multiplexed in the second resource and output for the second TRP.

[0033]

[0033] In some implementations, the second configuration further identifies a third resource for multiplexing CSI reports, and the processing system is further configured to select the second resource for transmitting the second set of CSI reports based on a determination that the third resource overlaps with the first resource in a slot and the second resource does not overlap with the first resource in the slot.

[0034]

[0034] In some implementations, at least one configuration is a single configuration that identifies a first resource for multiplexing CSI reports to be sent to a first TRP and a second resource for multiplexing CSI reports to be sent to a second TRP, a first set of CSI reports is multiplexed in the first resource and output for the first TRP, and a second set of CSI reports is multiplexed in the second resource and output for the second TRP.

[0035]

[0035] Another inventive aspect of the subject matter described in this disclosure may be implemented in a non-transitory computer-readable medium. The non-transitory computer-readable medium may store one or more instructions for wireless communication. When executed by one or more processors of a UE, the one or more instructions cause the one or more processors to receive at least one configuration that identifies a resource for multiplexing CSI reports that may collide during a slot; determine that a plurality of CSI reports in a first set of CSI reports to be sent to a first TRP or a second set of CSI reports to be sent to a second TRP may collide during the slot; and transmit at least one of the first set of CSI reports to the first TRP or the second set of CSI reports to the second TRP according to the at least one configuration, wherein the first set of CSI reports or the second set of CSI reports is multiplexed in the resource.

[0036]

[0036] In some implementations, at least one configuration identifies a plurality of resources, and the one or more instructions further cause the UE to select a resource for multiplexing CSI reports based on the payload size of the first set of CSI reports or the second set of CSI reports.

[0037]

[0037] In some implementations, one or more instructions that cause the UE to determine that multiple CSI reports may collide within a slot cause the UE to determine that a first CSI report and a second CSI report are scheduled in overlapping resources within the slot.

[0038]

[0038] In some implementations, one or more instructions further cause the UE to determine a first association between a first set of CSI reports and a first TRP and a second association between a second set of CSI reports and a second TRP.

[0039]

[0040]

[0042]

[0042] In some implementations, a first set of CSI reports and a second set of CSI reports are transmitted in separate resources.

[0043]

[0043] In some implementations, the second set of CSI reports is a subset of non-colliding CSI reports of a set of CSI reports having a plurality of CSI reports that may collide within a slot.

[0044]

[0044] In some implementations, the second set of CSI reports includes one or more CSI reports selected from a set of CSI reports having a plurality of CSI reports that may collide within a slot according to one or more prioritization criteria.

[0045]

[0045] In some implementations, the separate resources do not overlap.

[0046]

[0046] In some implementations, one or more instructions that cause the UE to receive at least one configuration cause the UE to receive a first configuration that identifies a first resource for multiplexing CSI reports, and to receive a second configuration that identifies a second resource for multiplexing CSI reports, where a first set of CSI reports is multiplexed in the first resource and transmitted to a first TRP, and a second set of CSI reports is multiplexed in the second resource and transmitted to a second TRP.

[0047]

[0047] In some implementations, the second configuration further identifies a third resource for multiplexing CSI reports, and one or more instructions further cause the UE to select a second resource for transmitting the second set of CSI reports based on a determination that the third resource overlaps with the first resource in a slot and the second resource does not overlap with the first resource in the slot.

[0048]

[0048] In some implementations, at least one configuration is a single configuration that identifies a first resource for multiplexing CSI reports to be transmitted to a first TRP and a second resource for multiplexing CSI reports to be transmitted to a second TRP, where a first set of CSI reports is multiplexed in the first resource and transmitted to a first TRP, and a second set of CSI reports is multiplexed in the second resource and transmitted to a second TRP.

The apparatus includes means for receiving at least one configuration for identifying resources for multiplexing CSI reports that may collide within a slot; means for determining that a plurality of CSI reports, a first set of CSI reports to be transmitted to a first TRP or a second set of CSI reports to be transmitted to a second TRP, have a potential to collide within a slot; and means for transmitting at least one of a first set of CSI reports to the first TRP or a second set of CSI reports to the second TRP according to at least one configuration, where the first set of CSI reports or the second set of CSI reports are multiplexed in the resources.

[0050]

[0053]

[0053] In some implementation forms, the first association and the second association are determined based on at least one of: a first other configuration that identifies a first resource for transmitting a CSI report as being associated with a first TRP, and a second other configuration that identifies a second resource for transmitting a CSI report as being associated with a second TRP; or another configuration that identifies a first CSI report configuration as being associated with a first TRP and a second CSI report configuration as being associated with a second TRP.

Best Mode for Carrying Out the Invention

[0066]

[0073] Like reference numerals and symbols in the various drawings indicate like elements.

[0067]

[0074] The following description is directed to several implementations for the purpose of illustrating the inventive aspects of the present disclosure. However, one of ordinary skill in the art will readily recognize that the teachings of this specification can be applied in many different ways. Some of the examples in this disclosure are based on wireless and wired local area network (LAN) communications according to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 wireless standard, the IEEE 802.3 Ethernet® standard, and the IEEE 1901 power line communication (PLC) standard. However, the described implementations can be implemented in any device, system, or network capable of transmitting and receiving radio frequency signals according to any of the wireless communication standards including, but not limited to, 3G, 4G, or 5G, or further implementations thereof, such as systems utilizing IEEE 802.11 standards, Bluetooth® standards, code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), Global System for Mobile Communications (GSM®), GSM / General Packet Radio Service (GPRS), Enhanced Data GSM Environment (EDGE), Terrestrial Trunked Radio (TETRA), Wideband CDMA (W-CDMA®), Evolution-Data Optimized (EV-DO), 1xEV-DO, EV-DO RevA, EV-DO RevB, High Speed Packet Access (HSPA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Evolved High Speed Packet Access (HSPA+), Long Term Evolution (LTE), AMPS, or any other known signals.

[0068]

[0075] In some wireless electrical communication systems, a user equipment (UE) may receive multiple downlink control information (DCI) communications from multiple transmission and reception points (TRPs) in order to schedule downlink transmissions from the multiple TRPs to the UE. In such a case, the UE may monitor each control resource set (CORESET) for the multiple DCIs, where each CORESET is associated with a specific TRP. Moreover, in such a case, the UE may provide uplink transmissions to the multiple TRPs respectively.

[0069]

[0076] For example, the UE may transmit channel state information (CSI) reports for the multiple TRPs in one or more physical uplink control channels (PUCCH). Sometimes, the UE may be scheduled to transmit multiple CSI reports to a TRP in overlapping resources, thereby causing collisions of the multiple CSI reports. In some wireless electrical communication systems, the UE may multiplex multiple colliding CSI reports in resources allocated to the UE (such as PUCCH resources) in a configuration (such as in the multi-CSI-PUCCH-ResourceList field of the PUCCH configuration).

[0070]

[0077] However, multiplexing CSI reports targeting multiple TRPs in a resource may prevent a TRP from identifying or decoding the CSI report targeting that TRP. For example, when the backhaul between TRPs is not ideal (such as a backhaul that cannot meet a threshold or has a latency that does not permit joint scheduling), a TRP may lack information regarding the scheduling decisions of another TRP, and thus, the TRP may not be able to identify the CSI report targeting the TRP from the multiple multiplexed CSI reports.

[0071]

[0078] Some of the techniques and apparatuses described herein enable multiplexing CSI reports in multiple TRP scenarios. For example, some of the techniques and apparatuses described herein enable a UE to receive at least one configuration for identifying one or more resources (such as those in the multi-CSI-PUCCH-ResourceList field of the PUCCH configuration) for multiplexing CSI reports that may collide within a slot (such as CSI reports scheduled on overlapping PUCCH resources within the slot).

[0072]

[0079] In some aspects, the UE may receive such a configuration from a first TRP and may not receive such a configuration from a second TRP. Thus, the UE may transmit the CSI reports multiplexed in the resources identified in that configuration to the first TRP and may transmit the CSI reports not multiplexed in the resources (such as in each resource initially allocated for such CSI reports in the CSI report configuration) to the second TRP. The UE may select one or more CSI reports scheduled in non-overlapping resources according to one or more prioritization criteria, for example, for transmission to the second TRP.

[0073]

[0080] In some aspects, the UE may receive from a first TRP a first configuration identifying one or more first resources for multiplexing CSI reports targeted at the first TRP, and may receive from a second TRP a second configuration identifying one or more second resources for multiplexing CSI reports targeted at the second TRP. Alternatively, the UE may receive from either the first TRP or the second TRP a single configuration identifying one or more first resources for multiplexing CSI reports targeted at the first TRP and one or more second resources for multiplexing CSI reports targeted at the second TRP. In any scenario, the UE may transmit to the first TRP a CSI report multiplexed in a first resource among the one or more first resources, and may transmit to the second TRP a CSI report multiplexed in a second resource among the one or more second resources. In such a case, the UE may select the first resource and the second resource based on the payload size of the CSI report or based on a determination that the first resource and the second resource do not overlap.

[0074]

[0081] Certain implementations of the subject matter described in this disclosure may be implemented to realize one or more of the following potential advantages. A UE may multiplex sets of CSI reports, each targeting a plurality of TRPs, in separate resources. This enables identification, discrimination, and decoding of sets of CSI reports by the TRPs, which may not be possible in some cases when sets of CSI reports, each targeting a plurality of TRPs, are multiplexed in the same resource. Moreover, the UE may transmit the multiplexed sets of CSI reports to the TRPs using transmission parameters (such as, among other examples, beams or transmit power) that are specific to the TRPs, thereby potentially improving transmission performance and reliability. Some implementations described herein enable multiplexing of sets of CSI reports, each targeting a plurality of TRPs, in a non-ideal backhaul condition. In this case, the TRP may receive the CSI reports with reduced latency, thereby potentially improving the relevance of the CSI for determining the current channel state. In contrast, when sets of CSI reports, each targeting a plurality of TRPs, are multiplexed in the same resource, a first TRP may decode the CSI for a second TRP and transmit that CSI to the second TRP, which may increase the latency in a non-ideal backhaul condition. Moreover, by multiplexing sets of CSI reports, collisions between CSI reports are avoided without dropping one or more CSI reports, thereby potentially improving the reliability and robustness of the CSI reports.

[0075]

[0082] FIG. 1 is a block diagram conceptually illustrating an example of a wireless network 100. The wireless network 100 may be any other wireless network, such as an LTE network, or a 5G or NR network. The wireless network 100 may include several BSs 110 (shown as BS110a, BS110b, BS110c, and BS110d) and other network entities. A BS is an entity that communicates with user equipment (UE) and, among other examples, may be a base station, NR It may also be referred to as a BS, Node B, gNB, 5G Node B (NB), access point, or transmission and reception point (TRP). Each BS may provide communication coverage for a specific geographical area. In 3GPP, the term "cell" can refer to the coverage area of a BS, the coverage area of the BS subsystem serving this coverage area, or a combination thereof, depending on the context in which this term is used.

[0076]

[0083] The BS may provide communication coverage for macrocells, picocells, femtocells, another type of cell, or a combination thereof. A macrocell may cover a relatively large geographical area (e.g., several kilometers in radius) and may enable unrestricted access by UEs subscribed to the service. A picocell may cover a relatively small geographical area and may enable unrestricted access by UEs subscribed to the service. A femtocell may cover a relatively small geographical area (e.g., a home) and may enable restricted access by UEs associated with the femtocell (e.g., UEs in a closed subscriber group (CSG)). The BS for a macrocell may sometimes be called a macro BS. The BS for a picocell may sometimes be called a pico BS. The BS for a femtocell may sometimes be called a femto BS or a home BS. In the example shown in FIG. 1, BS110a may be a macro BS for macrocell 102a, BS110b may be a pico BS for picocell 102b, and BS110c may be a femto BS for femtocell 102c. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0077]

[0084] In some examples, the cells are not necessarily fixed, and the geographical area of a cell may move according to the location of the mobile BS. In some examples, the BSs may be interconnected with each other and with one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces, such as direct physical connections, virtual networks, or combinations thereof, using any suitable transport network.

[0078]

[0085] The wireless network 100 may also include repeaters. A repeater is an entity that can receive the transmission of data from an upstream station (e.g., a BS or a UE) and send the transmission of that data to a downstream station (e.g., a UE or a BS). A repeater can also be a UE that can relay transmissions to other UEs. In the example shown in FIG. 1, the relay BS 110d can communicate with the macro BS 110a and the UE 120d to enable communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a repeater, a relay base station, a relay, etc.

[0079]

[0086] The wireless network 100 can be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs can have different transmission power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS can have a high transmission power level (e.g., 5 - 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmission power levels (e.g., 0.1 - 2 watts).

[0080]

[0087] The network controller 130 can be coupled to a set of BSs and can coordinate and control these BSs. The network controller 130 can communicate with the BSs via a backhaul. The BSs can also communicate with each other directly or indirectly, for example, via a wireless or wireline backhaul.

[0081]

[0088] UE 120 (e.g., 120a, 120b, 120c) can be distributed throughout the wireless network 100, and each UE can be fixed or mobile. The UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, etc. The UE can be a cellular phone (e.g., a smartphone), 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 instrument, a biosensor / biodevice, a wearable device (smartwatch, smart clothing, smart glasses, smart list band, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music device or a video device, or a satellite radio), a vehicle component or vehicle sensor, a smart meter / smart sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless medium or a wired medium.

[0082]

[0089] Some UEs may be regarded as machine type communication (MTC) UEs or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and eMTC UEs can communicate with, for example, a base station, another device (such as a remote device), or some other entity, including robots, drones, remote devices, sensors, meters, monitors, location tags, etc. A wireless node can provide connectivity for or to a network (such as a wide area network like the Internet or a cellular network) via, for example, a wired or wireless communication link. Some UEs may be regarded as Internet of Things (IoT) devices or implemented as narrowband Internet of Things (NB-IoT) devices. Some UEs may be regarded as customer premises equipment (CPE). UE120 may be included within a housing that stores components of UE120, such as processor components, memory components, similar components, or combinations thereof.

[0083]

[0090] Generally, any number of wireless networks can be deployed within a given geographical area. Each wireless network may support a specific radio access technology (RAT) and operate on one or more frequencies. RAT may also be referred to as wireless technology, air interface, etc. Frequencies may also be referred to as carriers, frequency channels, etc. Each frequency may support a single RAT within a given geographical area to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network may be deployed.

[0084]

[0091] In some examples, access to the air interface may be scheduled, where a scheduling entity (e.g., a base station) allocates resources for communication between some or all of the devices and apparatuses within the service area or cell of the scheduling entity. Within the present disclosure, as further described below, a scheduling entity may be responsible for scheduling, allocating, reconfiguring, and releasing resources for one or more subordinate entities. That is, for scheduled communication, a subordinate entity utilizes resources allocated by the scheduling entity.

[0085]

[0092] A base station is not the only entity that may function as a scheduling entity. That is, in some examples, a UE may function as a scheduling entity that schedules resources for one or more subordinate entities (e.g., one or more other UEs). In this example, the UE functions as a scheduling entity and other UEs utilize resources scheduled by the UE for wireless communication. The UE may function as a scheduling entity in a peer-to-peer (P2P) network, a mesh network, or another type of network. In a mesh network example, in addition to communicating with the scheduling entity, the UEs may optionally communicate directly with each other.

[0086]

[0093] Accordingly, in a wireless communication network having a cellular configuration, a P2P configuration, and a mesh configuration, with scheduled access to time-frequency resources, a scheduling entity and one or more subordinate entities may communicate using the scheduled resources.

[0087]

[0094] In some aspects, two or more UEs 120 (such as those shown as UE120a and UE120e) may communicate directly using one or more sidelink channels (such as without using the base station 110 as a medium for communicating with each other). For example, the UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (which may include, for example, vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or similar protocols), mesh networks, or similar networks, or combinations thereof. In this case, the UE 120 may perform scheduling operations, resource selection operations, and other operations described elsewhere in this specification as being performed by the base station 110.

[0088]

[0095] FIG. 2 is a block diagram conceptually showing an example 200 of a base station (BS) 110 communicating with a user equipment (UE) 120. In some aspects, the base station 110 and the UE 120 may each be one of the base stations and one of the UEs in the wireless network 100 of FIG. 1, respectively. The base station 110 may be equipped with T antennas 234a - 234t, and the UE 120 may be equipped with R antennas 252a - 252r, where generally T≥1 and R≥1.

[0089]

[0096] At base station 110, transmission processor 220 receives data from data source 212 for one or more UEs, selects one or more modulation and coding schemes (MCSs) for each UE based on the channel quality indicator (CQI) received from the UE, processes (e.g., encodes and modulates) the data for each UE based on the selected (one or more) MCS for that UE, and may provide data symbols for all UEs. Transmission processor 220 may also process system information and control information (e.g., CQI requests, grants, upper layer signaling, etc.) (for, e.g., semi-static resource partitioning information (SRPI)), and may provide overhead symbols and control symbols. Transmission processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signal (CRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). Transmission (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on data symbols, control symbols, overhead symbols, or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 232a - 232t. Each modulator 232 may process each output symbol stream (for, e.g., OFDM) to obtain an output sample stream. Each modulator 232 may further process the output sample stream (e.g., convert to analog, amplify, filter, and upconvert) to obtain a downlink signal. The T downlink signals from modulators 232a - 232t may be transmitted via T antennas 234a - 234t, respectively. According to various aspects described in more detail below, the synchronization signal may be generated using location coding to convey additional information.

[0090]

[0097] In UE120, antennas 252a - 252r can receive downlink signals from base station 110 or other base stations and can provide the received signals to respective demodulators (DEMOD) 254a - 254r. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 can further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 256 can obtain received symbols from all R demodulators 254a - 254r, perform MIMO detection on the received symbols when applicable, and provide the detected symbols. The receive processor 258 can process the detected symbols (e.g., demodulate and decode), provide the decoded data for UE120 to the data sink 260, and provide the decoded control information and system information to the controller or processor (controller / processor) 280. The channel processor can determine the 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 UE120 can be included within the housing.

[0091]

[0098] On the uplink, at UE 120, transmission processor 264 may receive and process data from data source 262 and control information from controller / processor 280 (for example, for reports including RSRP, RSSI, RSRQ, CQI, etc.). Transmission processor 264 may also generate reference symbols for one or more reference signals. Symbols from transmission processor 264 may be precoded by TX MIMO processor 266 when applicable and further processed by modulators 254a - 254r (for example, for DFT-s-OFDM, CP-OFDM, etc.) and transmitted to base station 110. At base station 110, uplink signals from UE 120 and other UEs are received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 when applicable, and further processed by receive processor 238 to obtain the decoded data and control information sent by UE 120. Receive processor 238 may provide the decoded data to data sink 239 and the decoded control information to a controller or processor (controller / processor) 240. Base station 110 includes communication unit 244 and may communicate with network controller 130 via communication unit 244. Network controller 130 may include communication unit 294, a controller or processor (controller / processor) 290, and memory 292.

[0092]

[0099] In some implementations, controller / processor 280 may be a component of a processing system. A processing system generally may refer to a system or series of machines or components that receive inputs, process the inputs, and generate a set of outputs (which may be passed to other systems or components of UE 120, for example). For example, the processing system of UE 120 may refer to a system that includes various other components or sub-components of UE 120.

[0093]

[0100] The processing system of UE120 can interface with other components of UE120 and can process information received from other components (such as inputs or signals), output information to other components, and the like. For example, the chip or modem of UE120 can include a processing system, a first interface for receiving or acquiring information, and a second interface for outputting, transmitting, or providing information. In some cases, the first interface can refer to the interface between the processing system of the chip or modem and the receiver, and thus, UE120 can receive an information or signal input, and the information can be passed to the processing system. In some cases, the second interface can refer to the interface between the processing system of the chip or modem and the transmitter, and thus, UE120 can transmit an information output from the chip or modem. Those skilled in the art will readily recognize that the second interface can also acquire or receive an information or signal input, and the first interface can also output, transmit, or provide information.

[0094]

[0101] The controller / processor 240 of the base station 110, the controller / processor 280 of UE120, or any other component(s) of FIG. 2 can implement one or more techniques associated with multiplexing CSI reports in a multi-TRP scenario, as will be described in more detail elsewhere in this specification. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of UE120, or any other component(s) (or combination of components) of FIG. 2 can implement or direct the operations of, for example, process 800 of FIG. 8 or other processes described herein. Memories 242 and 282 can store data and program code for the base station 110 and UE120, respectively. The scheduler 246 can schedule UEs for data transmission on the downlink, uplink, or a combination thereof.

[0095]

[0102] When the stored program code is executed by the controller / processor 280 or other processors and modules in the UE120, it may cause the UE120 to perform the operations described with respect to the process 800 of FIG. 8 or other processes described herein.

[0096]

[0103] In some aspects, the UE120 includes, among other things, means (using, among other things, the antenna 252, DEMOD254, MIMO detector 256, receive processor 258, or controller / processor 280) for receiving at least one configuration for identifying resources for multiplexing CSI reports that may collide within a slot, a first set of CSI reports to be transmitted to a first TRP, or a second set of CSI reports to be transmitted to a second TRP, means (using, among other things, the controller / processor 280 or memory 282) for determining that a plurality of CSI reports, where a first set of CSI reports to be transmitted to a first TRP or a second set of CSI reports to be transmitted to a second TRP, may collide within a slot, and means (using, among other things, the controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD254, or antenna 252) for transmitting at least one of the first set of CSI reports to the first TRP or the second set of CSI reports to the second TRP according to at least one configuration, where the first set of CSI reports or the second set of CSI reports are multiplexed in the resources, or combinations thereof. In some aspects, such means may include one or more components of the UE120 described with respect to FIG. 2.

[0097]

[0104] Although the blocks in FIG. 2 are shown as separate components, the functions described above with respect to those blocks may be implemented in a single hardware, software, or combined component, or various combinations of components. For example, the functions described with respect to the transmit processor 264, receive processor 258, TX MIMO processor 266, or another processor may be performed by the controller / processor 280 or under the control of the controller / processor 280.

[0098]

[0105] FIG. 3 is a block diagram conceptually showing an exemplary frame structure 300 in a wireless network. In some aspects, the frame structure 300 can be for frequency division duplexing (FDD) in a wireless network that can include a 5G NR wireless network or another type of wireless network. The transmission timeline for each of the downlink and uplink can be divided into units of wireless frames (sometimes called frames). Each wireless frame can have a predetermined duration (e.g., 10 milliseconds (ms)) and can be divided into a set of Z (Z≥1) subframes (having indices, e.g., from 0 to Z - 1). Each subframe can have a predetermined duration (e.g., 1 ms) and can include a set of slots (e.g., 2 m slots per subframe are shown in FIG. 3, where m is the numerology used for transmission, such as 0, 1, 2, 3, or 4, among others). Each slot can include a set of L symbol periods. For example, each slot can include 14 symbol periods, 7 symbol periods, or another number of symbol periods (as shown in FIG. 3, for example). When a subframe includes two slots (e.g., when m = 1), the subframe can include 2L symbol periods, where the 2L symbol periods in each subframe can be assigned indices from 0 to 2L - 1. In some aspects, the scheduling unit for FDD can be, among others, frame - based, subframe - based, slot - based, or symbol - based.

[0099]

[0106] In this specification, among other examples, several techniques are described with respect to frames, sub-frames, or slots. These techniques can be equally applied to other types of wireless communication structures that, in 5G NR, among other examples, can be referred to using terms other than "frame", "sub-frame", or "slot". In some aspects, the wireless communication structure can refer to a periodic time-bounded communication unit defined by a wireless communication standard or protocol. Additionally or alternatively, a configuration of the wireless communication structure different from that shown in FIG. 3 can be used.

[0100]

[0107] FIG. 4 is a block diagram conceptually showing an exemplary slot format 410 with a normal cyclic prefix. The available time-frequency resources can be partitioned into resource blocks. Each resource block can cover a set of sub-carriers (e.g., 12 sub-carriers) within one slot and can include several resource elements. Each resource element can cover one sub-carrier (e.g., temporally) during one symbol period and can be used to send one modulation symbol that can be a real-valued or complex-valued.

[0101]

[0108] For each of the downlink and uplink for FDD in some telecommunication systems (e.g., NR), an interleaving structure can be used. For example, Q interleaves with indices from 0 to Q - 1 can be defined, where Q can be equal to 4, 6, 8, 10, or some other value. Each interleave can include slots that are separated by Q frames. In particular, interleave q can include slots q, q + Q, q + 2Q, etc., where q ∈ {0,..., Q - 1}.

[0102]

[0109] A UE may be located within the coverage of multiple BSs. To serve the UE, one of these BSs may be selected. The serving BS may be selected based on various criteria such as, among other examples, received signal strength, received signal quality, or path loss, or a combination thereof. The received signal quality may be quantified by a signal-to-noise interference ratio (SNIR), or a reference signal received quality (RSRQ), or some other metric. The UE may operate in a dominant interference scenario where the UE may observe high interference from one or more interfering BSs.

[0103]

[0110] The example aspects described herein may be associated with NR or 5G technology, but aspects of the present disclosure may be applicable with other wireless communication systems. New Radio (NR) may refer to a new air interface (e.g., other than an orthogonal frequency division multiple access (OFDMA)-based air interface), or a radio configured to operate according to a fixed transport layer (e.g., other than the Internet Protocol (IP)). In an aspect, NR may utilize OFDM with a cyclic prefix (referred to herein as cyclic prefix OFDM or CP-OFDM) or SC-FDM on the uplink, may utilize CP-OFDM on the downlink, and includes support for half-duplex operation using time-division duplexing (TDD). In an aspect, NR may utilize OFDM with a cyclic prefix (referred to herein as CP-OFDM) or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) on the uplink, may utilize CP-OFDM on the downlink, and includes support for half-duplex operation using TDD. NR may include extended mobile broadband (eMBB) service targeting wide bandwidth (e.g., 80 megahertz (MHz) or more), millimeter wave (mmW) targeting high carrier frequencies (e.g., 60 gigahertz (GHz)), massive machine type communication (mMTC) targeting non-backward compatible MTC techniques, or mission critical targeting ultra-reliable low latency communication (URLLC) services.

[0104]

[0111] In some aspects, a single component carrier bandwidth of 100 MHz may be supported. An NR resource block may span 12 subcarriers with a subcarrier bandwidth of 60 or 120 kilohertz (kHz) over a duration of 0.1 millisecond (ms). Each radio frame may include 40 slots and may have a length of 10 ms. Thus, each slot may have a length of 0.25 ms. Each slot may indicate a link direction (e.g., DL or UL) for data transmission, and the link direction for each slot may be dynamically switched. Each slot may include DL / UL data as well as DL / UL control data.

[0105]

[0112] Beamforming may be supported and the beam direction may be dynamically configured. MIMO transmission using precoding may also be supported. The MIMO configuration in the DL may support up to 8 transmit antennas using multi-layer DL transmission of up to 8 streams and up to 2 streams per UE. Multi-layer transmission with up to 2 streams per UE may be supported. Aggregation of multiple cells may be supported using up to 8 serving cells. Alternatively, NR may support different air interfaces other than the OFDM-based interface. The NR network may include entities such as a central unit or a distributed unit.

[0106]

[0113] FIG. 5 shows an exemplary logical architecture of a distributed RAN 500. The 5G access node 506 may include an access node controller (ANC) 502. The ANC may be the central unit (CU) of the distributed RAN 500. The backhaul interface to the next generation core network (NG-CN) 504 may terminate at the ANC. The backhaul interface to an adjacent next generation access node (NG-AN) may terminate at the ANC. The ANC may include one or more TRPs 508 (which may also be called by some other terms such as BS, NR BS, Node B, 5G NB, AP, gNB). As explained above, the "TRP" may be used interchangeably with "cell".

[0107]

[0114] TRP508 can be a distributed unit (DU). The TRP can be connected to one ANC (ANC502) or two or more ANCs (not shown). For example, in the case of RAN sharing, radio as a service (RaaS), and service specific AND deployment, the TRP can be connected to two or more ANCs. The TRP can include one or more antenna ports. The TRP can be configured to serve traffic to UEs individually (e.g., dynamic selection) or together (e.g., joint transmission).

[0108]

[0115] The local architecture of RAN500 can be used to show the fronthaul definition. An architecture that supports a fronthauling solution across different deployment types can be defined. For example, the architecture can be based on transmission network capabilities (e.g., bandwidth, latency, jitter, etc.).

[0109]

[0116] The architecture can share features or components with LTE. According to an aspect, the next generation AN (NG-AN) 510 can support dual connectivity with NR. The NG-AN can share a common fronthaul for LTE and NR.

[0110]

[0117] The architecture can enable cooperation between TRP508s. For example, the cooperation can be preset within or across TRPs via the ANC502. According to an aspect, an interface between TRPs may not be required / may not exist.

[0111]

[0118] According to an aspect, a dynamic configuration of split logical functions may exist within the architecture of RAN500. The Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Media Access Control (MAC) protocols may be adaptively placed at the ANC or the TRP.

[0112]

[0119] According to various aspects, the BS may include a Central Unit (CU) (e.g., ANC502) or one or more Distributed Units (e.g., one or more TRP508).

[0113]

[0120] FIG. 6 shows an exemplary physical architecture of a distributed RAN600. A Centralized Core Network Unit (C-CU) 602 may host core network functions. The C-CU may be centrally deployed. The C-CU function may be offloaded (e.g., to Advanced Wireless Services (AWS)) to handle peak capacity.

[0114]

[0121] A Centralized RAN Unit (C-RU) 604 may host one or more ANC functions. Optionally, the C-RU may locally host core network functions. The C-RU may have a distributed deployment. The C-RU may be closer to the network edge.

[0115]

[0122] A Distributed Unit (DU) 606 may host one or more TRPs. The DU may be located at the edge of the network with radio frequency (RF) functions.

[0116]

[0123] FIG. 7 is a diagram showing an example 700 of multiplexing CSI reports in a multi-TRP scenario. As shown in FIG. 7, UE120 may communicate with a first TRP 705-1 and a second TRP 705-2 regarding CSI reports. In some aspects, the first TRP 705-1 or the second TRP 705-2 may correspond to the base station 110 as illustrated and described in FIG. 1, or the TRP508 as illustrated and described in FIG. 5.

[0117]

[0124] As shown in FIG. 7 and by reference numeral 710, the UE 120 may receive a CSI reporting configuration from the first TRP 705-1 or the second TRP 705-2. The CSI reporting configuration may identify one or more resources for which the UE 120 should transmit a CSI report. In some aspects, the resources identified by the CSI reporting configuration may be associated with a particular TRP 705. For example, the CSI reporting configuration may associate a resource with an identifier (such as an index value) corresponding to a particular TRP 705 (in such a case, the identifier may also be associated with a CORESET associated with the particular TRP 705). In this way, the UE 120 may identify the association between one or more CSI reports scheduled by the CSI reporting configuration and the particular TRP 705 to which the one or more CSI reports are targeted. In some aspects, the CSI reporting configuration may be associated with an identifier (such as an index value) that enables the UE 120 to identify the association between one or more CSI reports scheduled by the CSI reporting configuration and the particular TRP 705 to which the one or more CSI reports are targeted (for example, the identifier may also be associated with a CORESET associated with the particular TRP 705).

[0118]

[0125] Furthermore, UE120 may identify a non-ideal backhaul state between the first TRP and the second TRP. For example, UE120 may, based on a CSI reporting configuration that associates each resource with either the first TRP 705-1 or the second TRP 705-2 (in such a case, the PUCCH resource may have a configured association with an index value corresponding to the first TRP 705-1 or the second TRP 705-2), based on the CSI reporting configuration being associated with either the first TRP 705-1 or the second TRP 705-2 (in such a case, the CSI reporting configuration may have a configured association with an index value corresponding to the first TRP 705-1 or the second TRP 705-2), based on an explicit indication of a non-ideal backhaul state (such as in a radio resource control configuration), or based on a configuration of different hybrid automatic repeat request (HARQ) acknowledgement reports for the first TRP 705-1 and the second TRP 705-2, identify a non-ideal backhaul state. Based on determining a non-ideal backhaul state, UE120 may determine that CSI reports for the first TRP 705-1 and CSI reports for the second TRP 705-2 should not be multiplexed in the same resource.

[0119]

[0126] As shown by reference numeral 715, UE120 may receive a CSI multiplexing resource configuration from the first TRP 705-1 or the second TRP 705-2. The CSI multiplexing resource configuration may identify one or more resources that UE120 should use to multiplex CSI reports. For example, a CSI multiplexing resource configuration received from the first TRP 705-1 may identify one or more resources that UE120 should use to multiplex CSI reports to be transmitted to the first TRP 705-1.

[0120]

[0127] In some aspects, the UE 120 may receive a CSI multiplexing resource configuration from the first TRP 705-1 to identify one or more resources for multiplexing CSI reports targeted at the first TRP 705-1, and may not receive a CSI multiplexing resource configuration from the second TRP 705-2. In some aspects, the UE 120 may receive a first CSI multiplexing resource configuration from the first TRP 705-1 to identify one or more first resources for multiplexing CSI reports targeted at the first TRP, and may receive a second CSI multiplexing resource configuration from the second TRP 705-2 to identify one or more second resources for multiplexing CSI reports targeted at the second TRP. In some aspects, the UE 120 may receive, from either the first TRP 705-1 or the second TRP 705-2, a single CSI multiplexing resource configuration that identifies one or more first resources for multiplexing CSI reports targeted at the first TRP 705-1 and one or more second resources for multiplexing CSI reports targeted at the second TRP 705-2.

[0121]

[0128] As indicated by reference numeral 720, the UE 120 may identify one or more possible collisions between CSI reports that are scheduled to be transmitted in the same slot. For example, the UE 120 may identify a possible collision based on a determination that a first CSI report is to be transmitted in a first PUCCH resource that overlaps with a second PUCCH resource in which a second CSI report (in accordance with the CSI report configuration) is to be transmitted. As an example, one or more CSI report configurations received by the UE 120 from a first TRP 705-1 may schedule CSI reports for the first TRP 705-1 in the same first slot (such as in overlapping PUCCH resources). As another example, one or more CSI report configurations received by the UE 120 from a second TRP 705-2 may schedule CSI reports for the second TRP 705-2 in the same second slot (such as in overlapping PUCCH resources). Thus, for example, a first CSI report and a second CSI report that may collide may be for the first TRP 705-1 or may be for the second TRP 705-2.

[0122]

[0129] In such a case, UE120 may determine that CSI reports having a potential for collision should be multiplexed according to the CSI multiplexing resource configuration. In some aspects, UE120 may determine an association between colliding CSI reports and a particular TRP705 (e.g., based on the CSI report configuration as described above). For example, UE120 may determine that a first set of colliding CSI reports is associated with a first TRP705-1 (such as when the PUCCH resource for the first set of colliding CSI reports is associated with an index value also associated with the CORESET associated with the first TRP705-1), and may determine that a second set of colliding CSI reports is associated with a second TRP705-2 (such as when the PUCCH resource for the second set of colliding CSI reports is associated with an index value also associated with the CORESET associated with the second TRP705-2).

[0123]

[0130] In some aspects, UE120 may select a particular resource from among a plurality of resources identified in the CSI multiplexing resource configuration for multiplexing CSI reports. For example, UE120 may select a particular resource based on the payload size of the CSI reports to be multiplexed. In some aspects, UE120 may select a first resource from among a plurality of resources identified in a first CSI multiplexing resource configuration received from a first TRP705-1, and may select a second resource from among a plurality of resources identified in a second CSI multiplexing resource configuration received from a second TRP705-2. In such a case, the first resource and the second resource may not overlap.

[0124]

[0131] As indicated by reference numeral 725, the UE 120 may transmit a first set of CSI reports to the first TRP 705-1 and may transmit a second set of CSI reports to the second TRP 705-2. The UE 120 may transmit the first set of CSI reports and the second set of CSI reports according to one or more CSI multiplexing resource configurations received from the first TRP 705-1 or the second TRP 705-2.

[0125]

[0132] In some implementations, the UE 120 may receive from the first TRP 705-1 a CSI multiplexing resource configuration that identifies one or more resources for multiplexing CSI reports targeted at the first TRP 705-1, and may not receive a CSI multiplexing resource configuration from the second TRP 705-2. Accordingly, the UE 120 may transmit the first set of CSI reports multiplexed in the resources identified in the CSI multiplexing resource configuration to the first TRP 705-1, and may transmit the second set of CSI reports without multiplexing to the second TRP.

[0126]

[0133] For example, the UE 120 may transmit the second set of CSI reports to the second TRP 705-2 in respective resources allocated for such CSI reports in one or more CSI report configurations, as described above. The UE 120 may select one or more CSI reports scheduled in non-overlapping PUCCH resources (e.g., by one or more CSI report configurations) for inclusion in the second set of CSI reports. In some cases, the UE 120 may select one or more CSI reports scheduled in non-overlapping resources according to one or more prioritization criteria. In some aspects, the UE 120 may select one or more CSI reports scheduled in non-overlapping PUCCH resources (e.g., by one or more CSI report configurations) that do not overlap with the resources in which the multiplexed CSI reports are transmitted to the first TRP 705-1 for inclusion in the second set of CSI reports.

[0127]

[0134] In some other aspects, the UE 120 may receive from the first TRP 705-1 a first CSI multiplexing resource configuration that identifies one or more first resources for multiplexing CSI reports targeted at the first TRP 705-1, and may receive from the second TRP 705-2 a second CSI multiplexing resource configuration that identifies one or more second resources for multiplexing CSI reports targeted at the second TRP 705-2. Alternatively, the UE 120 may receive from either the first TRP 705-1 or the second TRP 705-2 a single CSI multiplexing resource configuration that identifies one or more first resources for multiplexing CSI reports targeted at the first TRP 705-1 and one or more second resources for multiplexing CSI reports targeted at the second TRP 705-2.

[0128]

[0135] In any scenario, the UE 120 may transmit to the first TRP 705-1 the CSI report multiplexed in the first resource among the one or more first resources, and may transmit to the second TRP 705-2 the CSI report multiplexed in the second resource among the one or more second resources. In such a case, the UE 120 may select the first resource and the second resource based on the payload size of the CSI report or based on a determination that the first resource and the second resource do not overlap. In some aspects, the UE 120 may select a first resource for transmitting a first set of CSI reports, and may select between a second resource and a third resource (among the one or more second resources) for transmitting a second set of CSI reports based on whether the second resource overlaps with the first resource or whether the third resource overlaps with the first resource.

[0129]

[0136] In some aspects, the UE 120 may determine that a first set of CSI reports to be transmitted in a first resource or a second set of CSI reports to be transmitted in a second resource has a potential to collide with uplink control information (UCI) communication or physical uplink shared channel (PUSCH) communication. In such aspects, the UE 120 may resolve potential collisions between CSI reports and UCI or PUSCH for each TRP 705 in a manner similar to the manner described herein to resolve potential collisions between CSI reports.

[0130]

[0137] FIG. 8 shows, for example, an exemplary process 800 performed by a UE. Process 800 shows operations associated with a UE, such as UE 120, performing multiplexing of CSI reports in a multi-TRP scenario.

[0131]

[0138] As shown in FIG. 8, in some aspects, process 800 may include receiving at least one configuration identifying a resource for multiplexing CSI reports that may collide during a slot (block 810). For example, the UE (using, among other examples, the UE's interface, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, or controller / processor 280) may receive at least one configuration identifying a resource for multiplexing CSI reports that may collide during a slot, as described above.

[0132]

[0139] As shown in FIG. 8, in some aspects, process 800 may include determining that a plurality of CSI reports in a first set of CSI reports to be sent to a first TRP or a second set of CSI reports to be sent to a second TRP have a potential to collide within a slot (block 820). For example, a UE (e.g., using the UE's processing system or controller / processor 280) may determine that a plurality of CSI reports in a first set of CSI reports to be sent to a first TRP or a second set of CSI reports to be sent to a second TRP have a potential to collide within a slot, as described above.

[0133]

[0140] As shown in FIG. 8, in some aspects, process 800 may include transmitting at least one of a first set of CSI reports to a first TRP or a second set of CSI reports to a second TRP according to at least one configuration, where the first set of CSI reports or the second set of CSI reports are multiplexed in resources (block 830). For example, a UE (e.g., using the UE's interface, controller / processor 280, transmission processor 264, TX MIMO processor 266, MOD254, or antenna 252) may transmit at least one of a first set of CSI reports to a first TRP or a second set of CSI reports to a second TRP according to at least one configuration, as described above. In some aspects, the first set of CSI reports or the second set of CSI reports are multiplexed in resources.

[0134]

[0141] Process 800 may include additional aspects, such as a single aspect or any combination of aspects, related to one or more other processes described below or elsewhere in this specification.

[0135]

[0142] In a first aspect, at least one configuration identifies a plurality of resources, and process 800 further includes selecting (using, for example, controller / processor 280 or memory 282) resources for multiplexing CSI reports based on the payload size of a first set of CSI reports or a second set of CSI reports. In a second aspect, determining, alone or in combination with the first aspect, that a plurality of CSI reports have a potential to collide within a slot includes determining that a first CSI report and a second CSI report are scheduled at overlapping resources within the slot.

[0136]

[0143] In a third aspect, alone or in combination with one or more of the first and second aspects, process 800 further includes determining (using, for example, controller / processor 280 or memory 282) a first association between a first set of CSI reports and a first TRP and a second association between a second set of CSI reports and a second TRP. In a fourth aspect, alone or in combination with one or more of the first to third aspects, the first association and the second association are determined based on at least one of a first other configuration that identifies a first resource for transmitting a CSI report as being associated with the first TRP, and a second other configuration that identifies a second resource for transmitting a CSI report as being associated with the second TRP, or another configuration that identifies a first CSI report configuration as being associated with the first TRP and a second CSI report configuration as being associated with the second TRP.

[0137]

[0144] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, prior to transmitting at least one of the first set of CSI reports or the second set of CSI reports, the process 800 further includes identifying a non-ideal backhaul state between the first TRP and the second TRP (e.g., using the controller / processor 280 or the memory 282 in the example). In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, the non-ideal backhaul state is identified based on at least one of another configuration indicating the non-ideal backhaul state, another configuration identifying different hybrid automatic repeat request (HARQ) acknowledgment reports for the first TRP and the second TRP, a first other configuration identifying a first resource for transmitting CSI reports as being associated with the first TRP, a second other configuration identifying a second resource for transmitting CSI reports as being associated with the second TRP, or another configuration identifying a first CSI report configuration as being associated with the first TRP and a second CSI report configuration as being associated with the second TRP.

[0138]

[0145] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, the first set of CSI reports and the second set of CSI reports are transmitted in separate resources. In an eighth aspect, alone or in combination with one or more of the first to seventh aspects, the second set of CSI reports is a non-colliding subset of CSI reports of a set of CSI reports having a plurality of CSI reports that may collide within a slot. In a ninth aspect, alone or in combination with one or more of the first to eighth aspects, the second set of CSI reports includes one or more CSI reports selected according to one or more prioritization criteria from a set of CSI reports having a plurality of CSI reports that may collide within a slot. In a tenth aspect, alone or in combination with one or more of the first to ninth aspects, the separate resources do not overlap.

[0139]

[0146] In the eleventh aspect, receiving at least one configuration, alone or in combination with one or more of the first to tenth aspects, includes receiving a first configuration that identifies a first resource for multiplexing CSI reports, and receiving a second configuration that identifies a second resource for multiplexing CSI reports. A first set of CSI reports is multiplexed on the first resource and transmitted to a first TRP, and a second set of CSI reports is multiplexed on the second resource and transmitted to a second TRP. In the twelfth aspect, alone or in combination with one or more of the first to eleventh aspects, the second configuration further identifies a third resource for multiplexing CSI reports, and the process 800 further includes selecting (using, for example, the controller / processor 280 or the memory 282 in the example) a second resource for transmitting the second set of CSI reports based on a determination that the third resource overlaps with the first resource in a slot and the second resource does not overlap with the first resource in the slot.

[0140]

[0147] In the thirteenth aspect, alone or in combination with one or more of the first to twelfth aspects, at least one configuration is a single configuration that identifies a first resource for multiplexing CSI reports to be transmitted to a first TRP and a second resource for multiplexing CSI reports to be transmitted to a second TRP. A first set of CSI reports is multiplexed on the first resource and transmitted to a first TRP, and a second set of CSI reports is multiplexed on the second resource and transmitted to a second TRP.

[0141]

[0148] Although FIG. 8 shows exemplary blocks of process 800, in some aspects, process 800 may include additional blocks, fewer blocks, different blocks, or blocks configured differently than those illustrated in FIG. 8. Additionally or alternatively, two or more of the blocks of process 800 may be performed in parallel.
