Methods and apparatuses for random access transmission

Abstract:

Embodiments of the present disclosure relate to methods and apparatuses for random access transmission. In example embodiments, a method implemented in a terminal device is provided. According to the method, a first transmission resource set from a plurality of transmission resource sets is selected based on one or more of the following: a beam-forming reciprocity capability of the terminal device, and a geometry of the terminal device in a serving area of a network device. The plurality of transmission resource sets are indicated in information for one or more random access configurations received from the network device and are respectively corresponding to different numbers of random access transmissions. Up to a first number of random access signals are transmitted to the network device in a random access request. The first number is corresponding to the first transmission resource set.
