Abstract: embodiments of the present disclosure relate to methods, devices and computer readable media for communication. a terminal device determines whether a radio link control, rlc, entity re-establishment for a radio bearer is to be performed, the radio bearer being configured with a transmission of data in an inactive state. if it is determined that the rlc entity re-establishment is to be performed, the terminal device re-establishes the rlc entity. after that, the terminal device transmits uplink data in the inactive state on the radio bearer. in this way, an rlc entity re-establishment is able to be handled for radio bearer configured with sdt if the terminal device determines that the rlc entity re-establishment needs to be performed for the sdt, thereby improving performance of the sdt procedure.

Abstract: a mobile station which communicates with a base station includes a transceiver configured to receive a downlink control channel, and a controller configured to determine whether c-rnti is included in the downlink control channel. the controller is further configured to determine that resource allocation in the downlink control channel overrides persistent downlink resource allocation for a transmission time interval (tti) if the c-rnti is included in the downlink control channel. the transceiver is further configured to receive a hybrid automatic repeat request (harq) transmission by using persistent downlink resources.

Abstract: embodiments of the present disclosure relate to a method, device and computer readable storage medium of communication. the method comprises receiving at a terminal device a dci for scheduling at least one pusch transmission from a network device. the dci comprises a first field indicating that the at least one pusch transmission is to be transmitted based on a srs resource set from a plurality of srs resource sets or the plurality of srs resource sets, and a second field indicating an index of the single srs resource set for transmitting the at least one pusch transmission. the method further comprises transmitting, by the terminal device, the at least one pusch transmission based on the dci to the network device. in this way, when supporting dynamic switching between single-trp transmission and multi-trp transmission, the newly-introduced overhead may be minimized.
