Random access response method, base station and terminal
First Claim
Patent Images
1. A random access response method, the method comprising:
- receiving a random access preamble sent in an enhanced manner;
determining level information corresponding to the random access preamble sent in the enhanced manner, wherein the level information comprises a preamble index;
determining a resource of a physical downlink control channel according to the preamble index, wherein the resource comprises at least one resource of a time resource or a frequency resource;
sending, on the resource, downlink control information (DCI) carried by the physical downlink control channel, wherein the DCI is used for scheduling the physical downlink shared channel (PDSCH); and
sending a random access response (RAR).

Abstract
A random access response method, a base station, and a terminal are disclosed. In an embodiment the method includes receiving a random access preamble sent in an enhanced manner, determining at least one of level information or resource information corresponding to the random access preamble sent in the enhanced manner and sending a random access response RAR of the random access preamble according to the at least one of the level information or the resource information, where the RAR is carried by a physical downlink shared channel PDSCH.
