Abstract: Methods, apparatuses, and systems are disclosed for compensating for cell identification delays that are beyond the control of the UE, in connection with standards-specified cell identification timing limits. In frequency bands including both beam sweeping and listen-before-talk (LBT) requirements, a cell identification procedure may be significantly delayed due to LBT failure at the base station and/or beam misalignment between the base station and the UE. Therefore, UE cell identification timing constraints may be dynamically adjusted to compensate for such delays. For example, the time window allowed for cell identification of a neighbor cell may be dynamically increased in response to determining that one or more SSBs were not available at the UE during an SMTC occasion. In some scenarios, if the timing increase exceeds a predetermined threshold, the UE may restart the cell identification procedure, e.g., on the same frequency layer or on a different frequency layer.

Abstract: Systems, methods, and circuitries are provided for performing sidelink communication. An example method includes receiving, via frequency and time resources of a physical sidelink shared channel (PSSCH), from a second UE, a signal encoding a sequence of bits corresponding to sidelink control information (SCI) stage 2; decoding the sequence of bits based on a SCI stage 2 scrambling initialization value (Cinit) to generate SCI stage 2 for a transport block (TB), wherein Cinit is determined based on at least a portion of a physical sidelink control channel (PSCCH) cyclic redundancy check (CRC) code; and receiving the TB from the first UE based on the SCI stage 2.

Abstract: This disclosure relates to techniques for performing wireless communications by rapidly moving user equipment device in communication with a network. The UE may adapt communication techniques in response to the UE's motion. For example, reference signals may be transmitted by the UE to additional transmission and reception points and/or using different configurations. Similarly, the UE may receive reference signals from additional transmission and reception points.
