    摘要: 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). The present disclosure discloses a method for responding to uplink scheduling request, user equipment and base station equipment. The method comprises: determining uplink scheduling request channel information; transmitting an uplink scheduling request signal generated according to the uplink scheduling request channel information to a base station, the uplink scheduling request signal containing UE identifier information; and receiving the uplink scheduling request response signal fed back by the base station, and acquiring an uplink transmission resource grant in the uplink scheduling request response signal by using the UE identifier information. Completing an uplink scheduling request by using the contention-based random access process is optimized, and the uplink scheduling request process may lead to simple flow and high communication efficiency.

    摘要: 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.
