Abstract: Embodiments of the present application provides an apparatus and a method for transmitting and receiving uplink data, and relates to the field of communication technologies. The method includes: performing uplink data transmission via a contention-based random access (RACH) procedure. The embodiments of the present application implement that, when transmitting uplink data in an RRC idle mode, the user equipment does not need to establish an RRC connection, and may directly transmit the uplink data via the RACH procedure, so that the power consumption of the UE may be reduced, and the waste of system resources may be reduced.

Abstract: The present disclosure provides a method of scheduling for a UE. The method includes dividing M UEs into N groups, wherein a distance metric between each UE in a group and the center of the group does not exceed a first predetermined threshold, where M and N are positive integers; pairing the N groups, wherein a distance metric between centers of the two paired groups is greater than a second predetermined threshold; and in a case where there is a group paired with a group to which a first UE for which scheduling is to be performed belongs, scheduling transmissions in different directions respectively for the first UE and the second UE from the paired group on the same time-frequency resource. The present disclosure also provides a signal transmission method, a base station, a UE and a computer readable medium.
