Abstract: Some aspects relate to apparatuses and methods for implementing mechanisms for a network to trigger the UE to obtain synchronization with one or more cell neighbors in the network. Some aspects of this disclosure relate to apparatuses and methods for implementing mechanisms for measuring and using TA for a beam group and for uplink signal multiplexing. For example, a UE includes a transceiver configured to wirelessly communicate with a serving cell and a processor communicatively coupled to the transceiver. The processor receives, from the serving cell, a first message indicating Physical Random Access Channel (PRACH) resource configuration associated with a neighbor cell. The processor further receives a second message to trigger transmission of a PRACH message to the neighbor cell. The processor further generates the PRACH message responsive to the second message and according to the PRACH resource configuration cell and transmits the PRACH message to the neighbor cell.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) to transmit a configured grant (CG) physical uplink shared channel (PUSCH) including an uplink control information (UCI) without transmitting a physical uplink control channel (PUCCH). The UE determines, based on a configuration received from the base station, a first set of CG PUSCHs. Each CG PUSCH of the first set of CG PUSCHs overlaps with the PUCCH, and is configured to transmit data from the UE to the base station. The UE further determines a second set of CG PUSCHs by excluding a third set of CG PUSCHs from the first set of CG PUSCHs. and select a CG PUSCH from the second set of CG PUSCHs to carry the UCI contained in the PUCCH. The UE further transmits the selected CG PUSCH including the UCI without transmitting the PUCCH.

Abstract: Some embodiments include a system, method, and computer program product for managing power consumption of a user equipment (UE) supporting sidelink discontinuous reception (SL-DRX) in a 5G wireless communications system. A UE determines a candidate slot for sending a signal based on data sensed in various periods over a history window. Some embodiments include a processor that can determine set of candidate slots that are sufficiently sensed based on sensed periods over a history window, and determine a subset of candidate slots of the set of candidate slots based at least on an occupancy threshold over the history window. The processor can select a candidate slot from the subset of candidate slots, and transmit via the transceiver, a first signal via the selected candidate slot.
