摘要： A method by a user equipment (UE) is described. The method includes receiving, from a base station, a MIB including first information related to a CORESET for a first search space set for the detected SS/PBCH block, monitoring a set of PDCCH candidates for the first search space set in the CORESET, wherein the CORESET comprises a first set of consecutive OFDM symbols and a second set of consecutive OFDM symbols, the CORESET is transmitted by a first time periodicity, the second set of consecutive OFDM symbols is transmitted after a first time offset from the first OFDM symbol for the first set of consecutive OFDM symbols. Further receiving second information indicating the first time offset.

摘要： The present disclosure provides a method performed by user equipment, and user equipment. The method performed by user equipment includes: if a medium access control (MAC) entity is configured with a configured uplink grant and if the configured uplink grant is activated, then determining whether the MAC entity is configured to use the configured uplink grant to transmit a MAC PDU, namely a MAC protocol data unit, obtained for a de-prioritized configured uplink grant; and if the MAC entity is configured to use the configured uplink grant to transmit the MAC PDU, then delivering the configured uplink grant to a hybrid automatic repeat request (HARQ) entity. In this way, the problem involving transmission of a de-prioritized MAC PDU stored in a HARQ process buffer can be solved, thereby improving the communication efficiency and reliability of a wireless communication system.

摘要： The present invention provides a method performed by user equipment and user equipment. The method comprises: receiving control information from a base station, the control information comprising a resource configuration related to a transmission on a Physical Sidelink Shared Channel (PSSCH); transmitting data to other UE through the PSSCH according to the control information; and transmitting to the base station first feedback information related to the transmission on the PSSCH and/or second feedback information related to a transmission on a Physical Downlink Shared Channel (PDSCH) between the base station and the UE. In this way, reliable data transmission can be achieved, thereby improving the reliability and stability of an entire communication system.
