Abstract

Methods and apparatuses for inter user equipment (UE) coordination signaling. A method of operating a UE includes determining a first set of first sidelink (SL) resources based on SL sensing and resource exclusion; selecting a first one or more SL resources within the first determined set for reservation, transmitting information about the first one or more SL resources, and receiving inter UE co-ordination information indicating whether a SL resource in the first one or more SL resources has a conflict. The method further includes transmitting on one of the first one or more SL resources, when the one SL resource does not have a conflict; and determining a second set of SL resources based on SL sensing and resource exclusion, and selecting a second one or more SL resources within the second set for transmission and reservation, when all of the first one or more SL resources have a conflict.

Claims18

Dependent claims

A first user equipment (UE) in a communication system, the first UE comprising:

a processor configured to:
decode a physical sidelink control channel (PSCCH), wherein the PSCCH includes a resource reservation period (Prsvp) field in units of milliseconds (ms);
and
convert Prsvp into P′rsvp in logical slots,
wherein:
Prsvp is multiplied by a ratio L/T and rounded-up based on a ceiling function to obtain P′rsvp,
T is a period in units of ms,
L is a value related to logical slots in a resource pool in the period T, and
L is determined as a number of slots corresponding to bits having value 1 within a bitmap, among a set of slots in the period T excluding at least one non-SL slot, at least one sidelink synchronization signal block (S-SSB) slot, and at least one reserved slot.
