Abstract: Systems, methods and circuitries are provided for performing UE autonomous selection in a vehicle-to-anything (V2X) communication environment, that includes one or more processors configured to schedule resources for discontinuous periodic transmission having a scheduled discontinuous time period in which scheduled resources are not transmitted. The one or more processors are further configured to perform a monitoring operation at the scheduled discontinuous time period, the monitoring operation comprising a monitoring for a collision of scheduled resources of the evaluating UE with scheduled resources of a competing UE, and selectively perform a corrective action when a collision of scheduled resources of the evaluating UE with scheduled resources of the competing UE is detected during the monitoring operation.

Abstract: Dynamic scheduling can be performed by 5G new radio in the licensed or unlicensed band. A UE can be polled by receiving a DCI that indicates dynamically updated resources. UE can be configured to find the DCI and use the resources to send a scheduling request (SR). Other aspects are described.

Abstract: A method and apparatus for determining a physical downlink control channel (PDCCH) search space monitoring configuration for a wireless device that specifies PDCCH monitoring for one subcarrier spacing (SCS) selected from a group of subcarrier spacings (SCSs) that are related to a spectrum in 5G new radio (NR) above 52.6 GHz are described. In one embodiment, the monitoring limits associated with each of the SCSs are applied per slot per CC and the user equipment (UE) decode complexity associated with performing the monitoring limits for the different SCSs in the group is equal. In one embodiment, the monitoring limits associated with each of the SCSs are for a slot group of a plurality of slots and are for application over a duration of the slot group.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for communications between user equipment. One of the methods includes receiving, by a first device and from a second device, sidelink control information indicating a resource reservation for a single-slot resource for the second device to use to communicate with the first device; determining, by the first device and based at least in part on the sidelink control information, whether a potential resource collision exists when the first device is scheduled to communicate with another device using the single-slot resource or when the single-slot resource is reserved by another device; and in response to determining that the potential resource collision exists, sending, by the first device and within a predetermined number of slots from a reference slot, a collision message to cause the second device to determine another single-slot resource to use to communicate with the first device.

Abstract: A user equipment (UE), or other network component can operate to configure different sets of resources including different sequence lengths for an uplink (UL) transmission via a UL channel. A first length or at least one of different second lengths can be selected to configure the UL transmission based on one or more conditions, which can include a coexisting radio access technology (RAT), a UE capability, an occupied channel bandwidth (OCB), the type of UL transmission or the like. The UL transmission can be based on at least one of: the first or the second sequence length such as for an initial access procedure based on the coexisting RAT and the OCB, for example.
