Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs. The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

Abstract: A user equipment (UE) may receive information, via radio resource control (RRC) signaling, regarding a search space of a physical downlink control channel (PDCCH) for obtaining downlink control information (DCI) from a radio access network (RAN) node. Based on a slot format (SF) index in the DCI, the UE may determine a slot format for communicating with the RAN node, and communicate with the RAN node in accordance with the slot format. Additionally, a UE may communicate UE capability information, which may include a maximum number of blind decode attempts (BDAs), to the RAN node. The UE may determine shortened channel control elements (sCCEs) to be used, by the RAN node, to transmit shortened downlink control information (sDCI) via a shortened physical downlink control channel (sPDCCH), obtain sDCI by monitoring the sPDCCH in accordance with the determined sCCEs, and communicate with the RAN node in accordance with the sDCI.

Abstract: A network device such as an evolved NodeB (eNB) or next generation NodeB (gNB) can configure a set of user equipment (UE) for cell reference signal (CRS) muting in order to provide better channel quality and power efficiency in communications. Where an eNB mutes CRS transmissions that are not needed by any UE, an improvement in downlink throughput and reduce connection drop rate can be generated. A CRS muting capability can be determined based on a user equipment (UE) capability information. According to the CRS muting capability of a UE, the CRS can be transmitted at frequency locations based on CRS muting configuration parameters.
