Abstract: This disclosure relates to techniques for a wireless device to perform gradual timing adjustments in a non-terrestrial wireless communication system. According to the techniques described herein, a wireless device may establish a non-terrestrial network based wireless link with a cellular base station. The wireless device may detect a trigger for changing a gradual timing adjustment rate from a first gradual timing adjustment rate to a second gradual timing adjustment rate. The wireless device may determine a time window for which to perform gradual timing adjustment at the second gradual timing adjustment rate. The wireless device may perform gradual timing adjustment at the second gradual timing adjustment rate for the time window.

Abstract: This disclosure relates to techniques for performing beam failure recovery in a high speed single frequency network scenario in a wireless communication system. A wireless device may establish a cellular link with a cellular network according to a single frequency network scheme. The wireless device may determine one or more beam failure detection resources for each of multiple transmission reception points associated with the cellular network. The wireless device may detect beam failure for one or more of the transmission reception points using the beam failure detection resources.

Abstract: This disclosure relates to performing beam failure recovery during an inter-cell connection involving a UE in communication with one or more base stations in a cellular communication system. In various embodiments, a user equipment determines one or more beam failures by monitoring one or more reference signals transmitted by one or more base stations, where the UE is connected to the one or more base stations. The UE further performs candidate beam detection by monitoring at least one candidate reference signal that is transmitted by one or more candidate base stations, where at least one candidate base station (a first candidate base station) is different from the one or more base stations to which the UE was previously communicating. The UE selects the first candidate base station based on the candidate beam detection, and transmits a beam failure recovery request (BFRQ) message to the first candidate base station based on the selection.

Abstract: In accordance with aspects of the present disclosure, a user equipment (UE) may receive a physical sidelink shared channel (PSSCH) transmission via a slot i and a sub-channel j. The UE may determine, within a resource block (RB) set k and a physical sidelink feedback channel (PSFCH) transmission occasion n, at least one interlace to use for a PSFCH transmission based at least in part on an index of the slot i, an index of the sub-channel j, a PSFCH periodicity, and a quantity of sub-channels in the RB set k. The UE may transmit the PSFCH transmission via the at least one interlace in the RB set k during the PSFCH transmission occasion n. The PSFCH transmission may include feedback for the PSSCH transmission.

Abstract: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of physical downlink control channel (PDCCH) monitoring in different search spaces sets independently from one another in order to manage different services optimally. A processor of the network device can be configured to receive physical downlink control channel (PDCCH) candidates of a PDCCH in a slot for channel estimation across search spaces of the slot. Different priorities can be determined among the PDCCH candidates in the slot based on a priority rule. Then a number of PDCCH candidates can be skipped/dropped from monitoring based on the different priorities of the PDCCH candidates to ensure that a threshold level of blind decoding operations across a plurality of slots of the PDCCH is being satisfied. The UE can monitor a portion of the PDCCH candidates while concurrently skipping another.

Abstract: Apparatuses, systems, and methods for beam reporting to facilitate multiple transmission and reception points, multi-TRPs, transmission schemes. A UE may receive, from a base station a configuration to report a beam quality based on at least one of a first reporting scheme and a second reporting scheme or a configuration of measurement resources for each TRP of a plurality of TRPs. The UE may report the beam quality based on the configuration or L1 measurements for multiple beam pairs and a recommended and/or assumed transmission scheme based on the configured measurement resources. The first reporting scheme may include the UE reporting at least one L1 measurement for multiple beams and the second reporting scheme may include the UE reporting at least one L1 measurement for multiple beam pairs. The recommended and/or assumed transmission scheme may be a non-coherent-joint transmission (NC-JT) transmission scheme and/or a single frequency network (SFN) transmission scheme.

Abstract: This disclosure relates to apparatuses and methods for providing and managing reception feedback for multicast and broadcast services (MBS). A base station (BS) may select and communicate, to a group of user equipment devices (UEs), configuration parameters for MBS communications, such as an indication of an MBS retransmission procedure for an MBS service. The BS may also transmit, to the group of UEs, an MBS data communication. A first UE may receive the MBS data communication, but may determine that the received MBS data communication is corrupted. The first UE may respond by transmitting, to the BS, a negative-acknowledgement (NACK) message. The BS may retransmit the MBS data communication either as an MBS transmission or as a unicast transmission, based on the configuration parameters. The first UE may monitor the appropriate resources to receive the retransmitted MBS data communication, based on the configuration parameters.

Abstract: This disclosure relates to techniques for performing multi-transmission and reception point operation in a wireless communication system. A plurality of transmission control indication states may be indicated for future use, e.g., using one or more separately identified lists. A subset of the indicated states may be activated. One or more states of the subset may be used for performing multi-transmission and reception point operation in a single downlink control information mode.
