context: CA was already supported for mode-3 in Rel-14. In Rel-15, CA for mode-4 was specified. The resource allocation procedure of Rel-14, which was based on sensing, was expanded to support multi-carrier transmission, while relying on the same core principles. Rules for power sharing, and to include priority were derived. A synchronization procedure for multiple carriers was derived. It includes priority rules for determining the synchronization resources. Sidelink packet duplication was introduced in the case of CA to improve the transmission reliability. - Support for 64-QAM. New transport block sizes and transport block size scaling were introduced to support 64-QAM. In addition, transmission uses rate-matching instead of the Rel-14 procedure where the last symbol was punctured. - Reduction of the maximum time between packet arrival at Layer 1 and resource selected for transmission. This value was reduced to 10ms, compared to 20ms for Rel-14 V2X. - Radio resource pool sharing between
