    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). Example embodiments of the present disclosure relate to the field of wireless communication technologies, and for example, to a method for determining a timing relationship, including: receiving a timing relationship set indication indicating a timing relationship set for use at a User Equipment (UE); determining the timing relationship set based on the timing relationship set indication; receiving timing relationship indication information indicating a timing relationship for use at the UE; and determining the timing relationship for use at the UE based on the timing relationship set and the timing relationship indication information. The disclosure implements a method and apparatus for dynamically changing a timing relationship set, saves power consumption of the UE, and ensures timely data transmission.

    Abstract: A method and device for reporting scheduling request are provided. The method includes the operations of acquiring a dedicated physical resource of a random access channel (RACH) configured to report a scheduling request, when the scheduling request is triggered, transmitting the RACH on the dedicated physical resource. The dedicated physical resource includes a plurality of periodic physical resources. Through this dedicated physical resource, the user equipment (UE) can report scheduling request in a contention-free random access way, and the capacity of a preamble sequence is improved and inter-cell interference is reduced.
