  • Patent number: 10999761
    Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive radio resource control (RRC) signaling that configures reception of a plurality of physical downlink shared channels (PDSCHs) in a frame. The frame may comprise multiple slots, including one or more downlink slots and one or more uplink slots. The UE may determine a subset of the PDSCHs, such that for each of the PDSCHs of the subset, corresponding consecutive slots do not overlap the uplink slots. The UE may set a number of bits of a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook equal to a number of PDSCHs in the determined subset.

  • Patent number: 10979988
    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.

  • Publication number: 20210037607
    Abstract: Systems and methods for PDCCH monitoring in NR systems. The UE provides to a serving cell UE capability information indicating a capability of the UE to monitor PDCCH. The UE capability information indicates a carrier aggregation capability larger than multiple serving cells and has a maximum number indication for a maximum number of PDCCH candidates that the UE can monitor per span. The serving cell transmits an RRC message to a UE in response to the UE capacity information. The RRC message has a per-slot and/or per-span indication to monitor PDCCHs on the serving cell for a maximum number of PDCCH candidates and non-overlapping CCEs. The UE monitors PDCCH candidates and, in the event that a span contains larger than a maximum number of PDCCH candidates or non-overlapping CCEs across multiple served cells, determines whether to monitor a particular PDCCH candidate in the span.
