Abstract

Systems and methods of providing NR V2V communications are disclosed. Channel sensing is used by both UEs to determine sets of candidate resources, and subsequently select a resource, for PSCCH and PSSCH transmissions. The transmitting UE selects the PSCCH resource and transmits a scheduling request using the PSCCH resource, while the receiving UE selects a PSCCH and the PSSCH resource and transmits a scheduling grant in the PSCCH containing transmission parameters and the PSSCH resource to the transmitting UE. When the scheduling request contains the candidate resources for the PSCCH transmission, the receiving UE uses the intersection of the candidate resources for the PSCCH transmission and the candidate resources for transmission to determine the PSCCH and the PSSCH resource.

Claims20

Dependent claims

An apparatus for a user equipment (UE) configured for vehicle-to-everything (V2X) sidelink communications in a fifth-generation (5G) system (5GS), the apparatus comprising:

processing circuitry;
and memory, the processing circuitry configured to:
decode sidelink control information (SCI) received from another UE, the SCI comprising a first SCI format,
the first SCI format indicating whether inter-UE coordination information is being provided or is being requested,
wherein when the first SCI format indicates that inter-UE coordination information is being provided, the processing circuitry is configured to determine a set of resources for a physical sidelink shared channel (PSSCH) transmission by the UE based on a reference slot indicated by the first SCI format,
wherein when the first SCI format indicates that inter-UE coordination information is being requested, the processing circuitry is configured to:
determine a set of resources for a PSSCH transmission by the other UE based on a resource selection window, the resource selection window determined from information in the first SCI format;
encode a second SCI format for transmission to the other UE in response to the first SCI format when the first SCI format indicated that inter-UE coordination information is being requested, the second SCI format encoded to provide the requested inter-UE coordination information including the set of resources determined for a PSSCH transmission by the other UE;
and
decode the PSSCH transmission from the other UE, the PSSCH transmission comprising data,
wherein the memory is configured to store an indication of the set of resources.
