Uplink access method, system and equipment for enhancing uplink access

Abstract

The embodiment of the invention discloses an uplink access method, which comprises the following steps: acquiring mapping relationship of reinforcement uplink access preamble signature, expanded acquisition indicator channel signature and reinforcement dedicated channel E-DCH resource index number; receiving an expanded acquisition indicator channel message from a base station, wherein the message carries the expanded acquisition indicator channel signature which is obtained by mapping user equipment access preamble signatures; detecting the expanded acquisition indicator channel signature which has the mapping relationship with the user equipment access preamble signature in the message by the user equipment to obtain a corresponding E-DCH resource index number; and performing uplink access by utilizing allocated resources corresponding to the E-DCH resource index number. The method realizes that E-AICH performs resource pointer for multiple UE simultaneously by configuring the mapping relationship between the access preamble signature and the E-AICH signature or between signature groups beforehand so as to reduce the access congestion and collision caused by insufficient resource pointer.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an uplink access method, system and equipment for enhancing uplink access. Background technique [0002] When the UE (User Equipment, user equipment) sends the preamble corresponding to the access R99 PRACH (Physical Random Access Channel, physical random access channel), or sends the preamble corresponding to the enhanced uplink access R8 and does not configure E-AICH (Enhance Acquisition Indicator Channel (acquisition indicator channel), when the NodeB (base station) detects the preamble signature, it responds to AI (Acquisition Indicator, acquisition indication) through AICH, and the AI ​​of the preamble signature response is +1 for ACK, and -1 for NACK. [0003] Each preamble signature is bound to a default resource configuration. When the preamble corresponding to the enhanced uplink access R8 is sent and E-AICH is configured, the AI ​​of the preamble signatur...

AI Technical Summary

Problems solved by technology

[0010] In the prior art, when multiple UEs perform uplink access at the same time and need to obtain resource indication by receiving the E-AICH in a given access slot, the E-AICH can only be used for the given access slot. A UE indicates resources, and UEs that do not obtain resource indications can only continue the access process, causing access congestion and increasing access interference
