摘要： An apparatus and system for reducing URLLC latency are described. A single packet mode is described in which, when a packet arrives at the PDCP layer for transmission, an indication is sent to a scheduler with the expected size of the packet after ciphering. The packet is then sent to the RLC layer and concurrently submitted to the ciphering engine to enable ciphering to occur in parallel with the other activities. The scheduler determines the expected TB size for transmission of the packet by determining the size of the PDCP, MAC, and RLC headers. The scheduler matches the resource allocation for transmission to the expected TB size.

摘要： A computer-readable storage medium that stores instructions for execution by one or more processors of a UE. The instructions to configure the UE for a streamlined transmission during low latency communications in a wireless network and to cause the UE to decode configuration signaling from a base station. The configuration signaling configures SR occasions for the UE. The UE detects availability of a UL data packet from an application layer, a size of the UL data packet being higher than a size of a TTI associated with a pre-defined slot boundary. An SR is encoded for transmission during one of the SR occasions, the SR including an indication based on the size. Control information is decoded in response to the SR, the control information including a scheduling grant based on the size of the UL data packet. The UL data packet is encoded for transmission using the scheduling grant.

摘要： Systems for providing prioritization of UL transmissions in a UE are described. The prioritization information is used to resolve resource conflicts among UL transmissions that include conflicts between high priority UL transmissions, between an aperiodic-channel state information transmission and a scheduling request, and between a low priority UL transmission and a high priority UL transmission when timeline conditions for multiplexing in a single UL transmission are not met. The prioritization is based on timing and priority of the UL transmissions to determine which of the UL transmissions to transmit and which to cancel. Additional prioritization is based on reception by the UE of a cancelation index or in an additional overlapping high priority UL grant received in a DCI of a PDCCH that overlaps with at least one other PDCCH associated with the UL transmissions.

摘要： 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.

摘要： 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.
