Embodiment Construction

[0076]Embodiments of the present disclosure have been described in detail with reference to the accompanying drawings. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and thus implement the present disclosure, rather than to imply any limitation on the scope of the present disclosure. Reference throughout the specification to features, advantages, or similar language does not imply that all features and advantages that may be achieved in accordance with the disclosure should be or are in any single embodiment of the disclosure. Rather, language referring to the features and advantages is understood to mean that a specific feature, advantage, or characteristic described in connection with an embodiment is included in at least one embodiment of the present disclosure. Furthermore, the described features, advantages, and characteristics of the disclosure may be combined in any suitable manner in one or more...

Abstract

Various embodiments of the present disclosure provide a method for random access. The method which may be performed by a terminal device comprises receiving, from a network node, information indicating an association between a downlink transmission and an uplink transmission (e.g. an association between a synchronization signal and physical broadcast channel block and a shared channel occasion) in a random access procedure. The association is based at least in part on configuration of random access resource (e.g. a random access occasion) and shared channel resource (e.g. the shared channel occasion) for an uplink message (e.g. including a preamble and physical uplink shared channel data) in the random access procedure. According to the embodiments of the present disclosure, an association between a synchronization signal and physical broadcast channel block and a shared channel occasion in a random access procedure can be configured flexibly and efficiently.

Description

technical field [0001] The present disclosure relates generally to communication networks and, more particularly, to methods and apparatus for random access. Background technique [0002] This section introduces various aspects that may contribute to a better understanding of the disclosure. Accordingly, the statements in this section are to be read in this manner and should not be construed as an admission of what is or is not prior art. [0003] Communication service providers and network operators are constantly faced with the challenge of delivering value and convenience to consumers (eg, by providing compelling network services and performance). With the rapid development of networking and communication technologies, wireless communication networks such as Long Term Evolution (LTE) networks and New Radio (NR) networks are expected to achieve high traffic capacity and end-user data rates with lower latency. In order to connect to a network node, a Random Access (RA) pr...
