Method and system for managing wireless communication in vehicle-to-anything communication system

A method for managing a wireless communication by a base station (BS) in a vehicle-to-anything (V2X) communication system, comprising:

• sending, to a user equipment (UE), a first message including configuration information for providing assistance information, for the wireless communication related to a vehicular service;
• receiving, from the UE, the first assistance information, wherein the first assistance information is obtained and is identified, by the UE, to be different from second assistance information indicated in a last transmission of assistance information, and wherein the first assistance information comprises a second data size and at least one of a second periodicity and a second timing offset;
• changing radio resources in a semi-persistent scheduling (SPS) configuration to the second data size and at least one of the second periodicity and the second timing offset from a first data size and at least one of a first periodicity and a first timing offset comprised in a previous SPS configuration;
• and
• transmitting, to the UE, a second message comprising the SPS configuration associated with the first assistance information.

A user equipment (UE) for managing a wireless communication in a vehicle-to-anything (V2X) communication system, the UE comprising:

• a transceiver;
• and
• at least one of processor coupled to the transceiver, wherein the at least one of processor is configured to:
• receive, from a base station (BS), a first message including configuration information for providing assistance information for the wireless communication related to a vehicular service,
• obtain first assistance information comprising a first data size and at least one of a first periodicity and a first timing offset,
• identify whether the obtained first assistance information is different from the second assistance information indicated in a last transmission of assistance information, wherein the second assistance information comprises a second data size and at least one of a second periodicity and a second timing offset,
• in case that the first assistance information is different from the second assistance information, transmit, to the BS, the first assistance information in response on the first message,
• receive, from the BS, a second message comprising a semi-persistent scheduling (SPS) configuration associated with the first assistance information, and
• perform the wireless communication with radio resources corresponding to the SPS configuration.

• change, radio resources in a semi-persistent scheduling (SPS) configuration to the second data size and at least one of the second periodicity and the second timing offset from a first data size and at least one of a first periodicity and a first timing offset comprised in a previous SPS configuration, and
• transmit, to the UE, a second message comprising the SPS configuration associated with the first assistance information.
