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: Embodiments of the present disclosure relate to methods and apparatuses of transmitting information and receiving information in a wireless communication system. In the method of transmitting information, the information comprises at least two of a reference signal and more than one radio resource control (RRC) message. The method comprises transmitting the at least two of the reference signal and the more than one RRC message by using a same time unit or at least two continuous time units, wherein the at least two of the reference signal and the more than one RRC message have a same time offset or different time offsets and have a same transmission periodicity or transmission periodicities which are different multiples of a predetermined periodicity. Thus, the interference to other systems or nodes can be limited, and the number of LBTs required for these signal transmissions can be reduced if they are transmitted on unlicensed spectrum.

Abstract: According to embodiments of the present disclosure, a solution for supporting repetitions for a plurality of downlink data transmission scheduled by signal downlink control information is proposed. A terminal device receives downlink control information scheduling a plurality of downlink data transmissions with repetitions from a network device. The terminal device determines a HARQ-ACK codebook for the plurality of downlink data transmissions based on a repetition pattern for the plurality of downlink data transmissions and the slot offset. The terminal device transmits a feedback for the repetitions for the downlink data transmissions based on the HARQ-ACK codebook to the network device. In this way, it achieves a flexible repetition patterns for the plurality of downlink data transmissions scheduled by signal DCI, which improves the coverage/reliability performance for data transmission.
