Access method and equipment in wireless network

Abstract

The invention discloses an access method and device in a wireless network. The method comprises the following steps: user equipment sends an access request for multiple cells on multiple access resources; and the user equipment receives feedback information of at least one piece of access equipment in response to the access request to carry out successive access interaction with the access equipment. According to the technical scheme provided by the embodiment of the invention, the multiple access resources are configured, so that the user equipment can initiate the access request for multiple cells on multiple access resources. One random access process is oriented to multiple cells, and multiple random access processes do not need to be separately initiated, thereby simplifying the signaling process, reducing the signaling cost and reducing the access delay.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an access method and equipment in a wireless network. Background technique [0002] In the future development of mobile communication systems, in order to better meet user needs and greatly increase network capacity and throughput, more access nodes will be introduced, that is, ultra-dense networks in the future. In ultra-dense networks, there is a large intersection of coverage between different access nodes. In addition, for heterogeneous network scenarios or multi-Radio Access Technology (RAT) network scenarios, overlapping coverage also exists. [0003] In the above scenario, there may be multiple layers of coverage at the same time for the user's location. Furthermore, there may be a need for users to access multiple cells. But at present, a random access procedure only targets one cell. According to the existing process, if a user needs to access ...
