    Abstract: A communication method and a terminal and a base station adapted to the method are provided. The communication method of a terminal includes: receiving a message containing information regarding a semi-persistent scheduling (SRS) configuration from a base station; determining whether a sub-frame configured with a non-adaptive re-transmission is identical to a sub-frame configured with an uplink grant according to the SPS configuration; and when: a sub-frame configured with a non-adaptive re-transmission is identical to a sub-frame configured with an uplink grant according to the SPS configuration; and the terminal does not have data to be first transmitted via the sub-frame configured with an uplink grant according to the SPS configuration, performing the non-adaptive re-transmission.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method performed by a terminal in a communication system is provided. The method includes receiving, from a base station, configuration information on a configured grant for uplink transmission, the configured grant being configured with an autonomous transmission; in case that a previous configured grant for a hybrid automatic repeat request (HARQ) process was not prioritized, a transmission of a first medium access control (MAC) protocol data unit (PDU) obtained for the HARQ process has not been performed, and a size of the first MAC PDU matches a size of a configured grant, identifying that the first MAC PDU has been obtained for the configured grant; and in case that the configured grant is a prioritized uplink grant, delivering the obtained first MAC PDU.

    Abstract: Method and a UE for managing an IDC issue. The UE includes a memory, a processor, coupled to the memory and communication module based on LTE RAT, configured to transmit capability information on a licensed carrier associated with a primary cell, wherein the UE supports a LAA operation. Further, the processor, coupled to the communication module based on LTE RAT, is configured to receive an IDC indication from the primary cell served by an eNB. Further, the processor, coupled to the communication module based on LTE RAT, configured to detect the IDC issue in an unlicensed band associated with a secondary cell. Further, the processor, coupled to the communication module based on LTE RAT, configured to transmit an IDC message comprising assistance information to the primary cell and receive a message to resolve the IDC issue based on the assistance information from the primary cell served by the eNB.

    Abstract: A communication method and system for converging a 5th generation (5G) communication system for supporting higher data rates beyond a 4th generation (4G) system with a technology for Internet of things (IoT) are provided. The communication method and system may be applied to intelligent services based on the 5G communication technology and the IoT-related technology. A method performed by a terminal for beam failure recovery (BFR) on a secondary cell (SCell) in a wireless communication system comprises receiving information for BFR on an SCell including a scheduling request configuration for the BFR on the SCell; detecting beam failure on the SCell based on whether a number of beam failure instances within a preconfigured time duration exceeds a preconfigured number; and, as a response to detecting the beam failure on the SCell, transmitting a scheduling request for the BFR on the SCell based on the scheduling request configuration.
