Abstract: A repeater configured to receive, on a side control channel from a component of a network, side control information including parameters at least for determining time domain resources on which to apply an indicated beam for uplink (UL) transmission reception or downlink (DL) transmission forwarding with a user equipment (UE) on an access link, determine, from the received parameters, whether to apply the indicated beam to a transmission (Tx) spatial filter, a reception (Rx) spatial filter, or both the Tx and Rx spatial filters and apply the indicated beam to the determined Tx spatial filter, Rx spatial filter, or both the Tx and Rx spatial filters for the determined time domain resources when forwarding the DL transmission to the UE or receiving the UL transmission from the UE for forwarding to the network.

Abstract: A user equipment (UE), a base station (e.g., next generation NodeB (gNB)), or other network component can operate to configure a beam failure recovery (BFR) timing based on a time offset and a number of symbols in a BFR procedure, as well as enable beam switching and bandwidth part (BWP) switching to be correlated. A beam failure recovery request (BFRQ) can be processed or transmitted in response to a detection of a beam failure. A beam failure recovery response (BFRR) can be generated via a physical downlink control channel (PDCCH) based on at least four slots after the BFRQ and a time offset for a non-terrestrial network (NTN).

Abstract: A user equipment (UE) may monitor a downlink frequency position to detect a synchronization block (SSB) from a cellular base station. When monitoring the downlink frequency position, the UE may be configured to use at least one step size in calculating a SSB frequency position. The UE may determine a subcarrier spacing (SCS) used by the cellular base station in response to monitoring the downlink frequency position, and the subcarrier spacing for one or more SSB transmissions may be determined at least in part based on the step size used in calculating the SSB frequency position. The UE may then utilize the determined subcarrier spacing of the one or more SSB transmissions in communicating with the cellular base station.

IPC: H04L5/00

Abstract: A user equipment (UE) may establish communication with a plurality of transmission reception points (TRPs) and determine one or more beam failures associated with a first or second TRP based on reference signals received from the first and second TRPs. The UE may then transmit a scheduling request requesting resources for indicating the beam failures associated with the first TRP or second TRPs. Upon receiving a response to the scheduling request allocating resources, the UE may then transmit, using allocated resources, a beam failure indication of the first one or more beam failures associated with the first TRP or second TRP. After receiving a beam failure response from the first or second TRP, the UE may then communicate with the first TRP and the second TRP using one or more new beams based on the beam failure indication and the beam failure response.

Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a base station and a processor communicatively coupled to the transceiver. The processor is configured to determine one or more configured grant (CG) transport blocks (TBs) of one or more CG uplink transmissions and determine one or more dynamic grant (DG) TBs of one or more DG uplink transmissions. The processor is further configured to determine that a first CG TB of the one or more CG TBs overlaps with a first DG TB of the one or more DG TBs in time and determine that a priority level of the first CG TB is lower than a priority level of the DG TB. The processor is further configured to determine that the priority level of the first CG TB is lower than the priority level of the first DG TB and transmit, in the first DG TB, a first DG uplink transmission corresponding to the first DG TB.

Abstract: Provided is a method for a user equipment (UE). The UE may performs at least one of: monitoring physical downlink control channels (PDCCHs) in a Type0-PDCCH common search space (CSS) set over one or two consecutive slots, starting from a slot index n_0, with a 480 kHz or 960 kHz subcarrier spacing (SCS); transmitting, to a base station (BS), a report of a UE capability related to search space configurations for multi-slot PDCCH monitoring; or performing a monitoring occasion (MO) shifting operation for a first group of search space (SS) sets in response to a determination that a second group of SS sets is updated.
