Abstract: A user equipment (UE) in a multiple transmission and reception point (multi-TRP) configuration having simultaneous connections with a first next generation node B (gNB) and at least one second gNB over a same carrier. The UE divides uplink (UL) resources into a plurality of groups, determines a spatial relation and a pathloss reference signal (RS) for each one of the plurality of groups based on a transmission configuration indication (TCI) indicating a quasi-co-location (QCL) source RS for a downlink channel and transmits UL data on the UL resources corresponding to each one of the plurality of groups to a respective one of the first gNB or the at least one second gNB.

Abstract: This disclosure relates to techniques for a wireless device to perform channel state information reporting. The wireless device may receive channel state information reporting configuration information. The channel state information reporting configuration information may include an indication to use a wideband precoding matrix indicator format for 3GPP release 16 type II channel state information reporting. The wireless device may perform channel state information reporting using a different reporting configuration than 3GPP release 16 type II channel state information reporting using a wideband precoding matrix indicator format based at least in part on the channel state information reporting configuration information. The wireless device may also or alternatively perform 3GPP type I channel state information reporting using a unified spatial basis selection framework for rank indicators of 3 and 4 for any number of channel state information reference signal ports.

Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. An example method generates SCI stage 1 and stage 2 for transmitting a transport block (TB) to a user equipment device (UE). The method includes determining the type of sidelink communication for transmitting the TB. An SCI stage 2 format is selected based on the type of sidelink communication. An SCI stage 2 payload is encoded in accordance with the selected SCI stage 2 format. The selected SCI stage 2 format value is encoded in an SCI stage 1 payload. The SCI stage 1 payload and SCI stage 2 payload are transmitted to the UE.

Abstract: Apparatuses, systems, and methods for multiplexing of PUCCH for beam failure recovery and other signals. A UE may determine a transmission dropping rule and a transmission power scaling rule for a PUCCH which is dedicatedly configured for secondary BFR transmission, such as a PUCCH-BFR, when it is multiplexed with BFR multiplexed with at least one other signal. The PUCCH-BFR and the at least one other signal may be multiplexed in a CC or in multiple CCs. The UE may determine a transmission dropping rule, e.g., so that UE can transmit an uplink signals with higher priority and drop the other uplink signal with lower priority to avoid beam collisions. The UE may determine a transmission power scaling rule, e.g., so the UE may scale transmission power within a CC and/or across CCs. The UE may multiplex the PUCCH-BFR with the at least one other signal according to the rules.

Abstract: Techniques for changing a Transmission Configuration Indication (TCI) state by a user equipment (UE) operating in a wireless communications system are provided. The UE receives a first message including a TCI state change command from a network and determines, based on the first message, whether a time offset/frequency offset (TO/FO) and a reception (Rx) beam for a new TCI state are known by the UE. Based on the determination, the UE calculates a time delay of the UE to be prepared to receive a reference signal with the new TCI state, generates a second message indicating the time delay of the UE for the new TCI state, and transmits the second message to the network.

Abstract: Systems and methods for utilizing inter-UE coordination regarding reserved resources of a sidelink (SL) resource pool are described herein. A first user equipment (UE) may identify that a first SL resource pool on a first radio access technology (RAT) overlaps with a second SL resource pool on a second RAT, sense for reservation signaling on the second SL resource pool to determine reserved resources on the second SL resource pool, and transmit resource reservation information indicating those reserved resources on SL on the first RAT. A second UE may receive the resource reservation information on the SL, identify, within the first SL resource pool, corresponding resources that overlap with the reserved resources of the second SL resource pool, select, from the first SL resource pool, transmission resources to use for a SL transmission by prioritizing resources other than the corresponding resources; and perform the SL transmission using those transmission resources.
