Abstract: A user equipment (UE) monitors for a synchronization signal block (SSB) to synchronize with a cell of a network. The UE monitors a frequency band during a discovery reference signal (DRS) window for a synchronization signal block (SSB) transmitted by a cell of the network, determines an SSB index based on information received from the cell of the network and synchronizes with the cell based on the SSB index.

Abstract: Disclosed are methods and systems to coordinate resource allocation between two UEs for sidelink communication. A receiving UE receiving sidelink communication from a transmitting UE may configure coordination resources used to coordinate sidelink communication between the two UEs. The receiving UE may receive from the transmitting UE data indicating resources reserved and intended to be used by the transmitting UE to transmit sidelink data to the receiving UE. The receiving UE may determine a coordination message used to indicate whether the resources reserved by the transmitting UE are available for use by the receiving UE to receive the sidelink data from the transmitting UE. The receiving UE may determine resources from the coordination resources to be used to carry the coordination message and may transmit the coordination message carried on the selected resources to indicate to the transmitting UE whether to use the reserved resources for the sidelink data.

Abstract: This disclosure relates to techniques for performing wireless communications including signaling resource allocation for multiple transport blocks (TBs) on either PUSCH or PDSCH using a single control element, such as a DCI. In various scenarios, the multiple TBs may be scheduled either at contiguous or at non-contiguous dime-domain resources. Various mechanisms are disclosed for performing signaling the resource allocation for the multiple TBs without introducing excessive signaling overhead.

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.

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.
