  • Publication number: 20230199733
    Abstract: A method and apparatus provide for low latency transmissions. A higher layer configuration can be received at a device. The higher layer configuration can be higher than a physical layer configuration. The higher layer configuration can indicate configuring the device with a low latency configuration for a low latency transmission mode in addition to a regular latency configuration for a regular latency transmission mode. The low latency transmission mode can have a shorter latency than the regular latency transmission mode. A packet can be received based on one of the low latency configuration and the regular latency transmission mode in a subframe n. A feedback packet can be transmitted in a following subframe n+p, where p<q when the received packet is based on the low latency configuration. The following subframe n+p can be the pth subframe from the subframe n.

  • Publication number: 20230189251
    Abstract: A wireless device (12) transmits signaling (26) which indicates that the wireless device (12) supports cross-slot scheduling. Support for cross-slot scheduling indicates a range of values that the wireless device (12) supports for a triggering offset (20). A triggering offset (20) is an offset between: (i) a slot containing downlink control information (14) that triggers a set (16) of aperiodic channel state information reference signal, CSI-RS, resources; and (ii) a slot in which the set (16) of aperiodic CSI-RS resources is transmitted. The signaling (26) may enable a network node (15) that receives the signaling (26) to correspondingly transmit, to the wireless device (12), a control message which configures the wireless device (12) with a triggering offset (20) that has a value within the indicated range of values.

  • Patent number: 11678278
    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.
