    Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. An apparatus and a method performed by the same in a wireless communication system are disclosed. The method includes: receiving configuration information from a base station; and receiving a downlink signal from the base station based on the configuration information, the downlink signal including downlink data. The downlink data includes a unicast physical downlink shared channel (PDSCH) and/or a multicast/broadcast PDSCH, the unicast PDSCH includes a dynamically scheduled unicast PDSCH and/or a unicast semi-persistent scheduling (SPS) PDSCH, and the multicast/broadcast PDSCH includes a dynamically scheduled multicast/broadcast PDSCH and/or a multicast/broadcast SPS PDSCH. The present disclosure improves the efficiency of uplink or downlink transmission.

    CPC classification number: H04W72/23

    Abstract: The present application relates to the field of wireless communication technologies, and in particular, to a PDCCH monitoring method, apparatus, electronic device and computer readable storage medium. The PDCCH monitoring method includes: determining PDCCH monitoring configuration on a target active downlink bandwidth part (BWP), after a current active downlink BWP is switched to the target active downlink BWP; performing a monitoring process on the PDCCH based on the PDCCH monitoring configuration on the target active downlink BWP. The present application achieves effective monitoring of the PDCCH on the switched active downlink BWP, saves power consumption of the UE, and ensures timely transmission of data.

    Abstract: A terminal and a method performed by the terminal in a wireless communication system are provided. The method includes receiving a RRC message including information related to a SPS HARQ deferral, performing at least one of multiplexing or prioritization among a first PUCCH and one or more uplink channels when the first PUCCH overlaps with the one or more uplink channels, identifying a PUCCH resource for a PUCCH transmission with HARQ-ACK information for SPS PDSCH receptions based on a result of performing at least one of the multiplexing or the prioritization in a first slot, determining a second slot based on the RRC message, when the PUCCH resource overlaps with at least one of a downlink symbol, an SS/PBCH block or a CORESET0, and transmitting the HARQ-ACK information for the SPS PDSCH receptions in the second slot.

    IPC: H04W72/04

    Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A technique for receiving a downlink control channel is provided that includes operations of determining whether a physical downlink shared channel (PDSCH) is received at a time-domain position n; determining, according to a result of the determining, a frequency-domain position of a bandwidth part (BWP) for receiving a physical downlink control channel (PDCCH) at a time-domain position n+1, and receiving the PDCCH at the BWP of the frequency-domain position. The technique determines the frequency-domain position of the BWP for receiving the PDCCH by determining whether it is necessary to receive the PDSCH at the time-domain position preceding the current time-domain position for receiving the PDCCH, greatly reducing or even eliminating the influence of the adjustment time interval for the user equipment (UE) to convert the BWP on the normal data reception of the UE, which ensures the receiving performance and the throughput level of the received data of the UE.
