Abstract: Systems and methods for control signaling for beam searching latency reduction are disclosed herein. A g Node B (gNB) may determine that a first Synchronization Signal Block (SSB) and a second SSB are to be spatially correlated and may select a first transmit (Tx) beam to transmit the first SSB and a second Tx beam to transmit the second SSB accordingly. The gNB may also transmit a correlation message including spatial correlation information to help a UE determine the spatial correlation. The UE may measure the first SSB on a first subset of a plurality of receive (Rx) beams and measure the second SSB on a second subset of the plurality of Rx beams, and select an Rx beam for one or both. In some embodiments, channel state information reference signals (CSI-RS) that are quasi co-located (QCLed) with a given SSB may be measured in place of the SSB.

Abstract: Systems and methods for beam indication for layer 1/layer 2 (L1/L2) centric inter-cell mobility are described herein. A base station may provide a user equipment (UE) with beam indications, in one or more transmission configuration indication (TCI) states, and may provide different beam indications for different search spaces (SSs), including UE-specific search space (USS) and common search space (CSS) within a same control channel resource set (CORESET). A UE may implicitly select a radio link monitoring (RLM) and beam failure detection (BFD) reference signal (RS) in accord with one or more methods, and in some cases may implicitly select an RLM/BFD RS based on one or more received TCI states or beam indications.

Abstract: A user equipment (UE), including a vehicle to everything (V2X) device, a baseband processor or other network device can operate in an unlicensed network to acquire a channel occupancy time (COT) for sidelink (SL) transmission and provide sidelink control information (SCI) with a first stage SCI in a physical sidelink control channel (PSCCH) and a second stage SCI in a physical sidelink shared channel (PSSCH). The first stage SCI or the second stage SCI can provide COT indications to a receiving UE device that enable COT sharing in a sidelink unlicensed COT (SL-U COT) for SL communication.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to determine a default beam for a dedicated PUCCH/SRS in a CC. The UE may determine a pathloss RS has been configured in the CC, e.g., responsive to the UE determining that spatial relationship information for a default transmission beam has not been configured and determine the default beam for transmissions based, at least in part, on the (configured) pathloss RS. Additionally, responsive to determining that the pathloss RS has not been configured in the CC, the UE may determine that no CORESETs/TCI states for a PDSCH in the CC have been configured and determine the default beam for transmissions based, at least in part, on a default transmission beam in another CC, a CC index, a PRACH procedure; a PUSCH transmission; an SRS transmission, and/or a PUCCH transmission.

Abstract: Technology for a user equipment (UE), operable for monitoring a physical downlink control channel (PDCCH) is disclosed. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein the predetermined monitoring occasion has a periodicity of P slots or P symbols with an offset Os. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein Os has an offset with respect to a first slot in subframe number zero (SFN #0). The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein P is a positive integer greater than zero.

Abstract: The present disclosure proposes configuration for TB processing over multi-slot, particularly Transmission Block over multi-slot (TBoMS) transmission. Specifically, such configuration for TBoMS may relate to at least one of size determination for TBoMS, scheduling for TBoMS transmission, resources determination and allocation for TBoMS transmission, and so on, and corresponding information related to such configuration can be acquired, set or determined appropriately, so that the TB processing over multi-slot can be performed accordingly.

Abstract: Technology for dual connectivity is disclosed. A user equipment (UE) can identify a first physical channel that includes a first uplink control information (UCI) and a second physical channel that includes a second UCI. The UE can select a priority level for the first physical channel and a priority level for the second physical channel. The UE can apply power scaling to a first physical channel transmission or a second physical channel transmission if a total transmit power of the UE would exceed a specific value during a period of time. The UE can scale a transmit power for the second physical channel if the priority level for the first physical channel is higher than the priority level for the second physical channel depending on a type of first UCI and a type of second UCI.
