Problems solved by technology

If two users are configured with the same E-HICH and the same signature sequence group, the base station cannot schedule these two users at the same time in the same TTI, which limits the scheduling flexibility
However, if a different signature sequence group or E-HICH is configured for each user, since a non-scheduled E-HICH has at most 20 code groups, when the number of users in the cell is greater than 20, at least two non-scheduled E-HICHs must be configured. -HICH, resulting in a larger control channel resource occupation, which reduces the physical resources used to transmit data
It can be seen that this resource allocation method limits the number of users supported by the system

Embodiment Construction

[0050] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0051] The feedback information transmission method of the embodiment of the present invention aims at the problem that the static configuration mode of the signature sequence group used in the non-scheduled transmission or the semi-persistent scheduled transmission in the prior art makes the control channel resources occupy a large amount and affects the number of users supported by the system. The network side pre-configures the corresponding relationship between E-PUCH physical resources and signature sequence groups or the corresponding relationship between E-PUCH physical resources and signature sequences. The physical resources of the E-PUCH and the corresponding relationship can determine the signature seq...

Abstract

The invention relates to the technical field of communications and discloses a feedback information transmission method and system and equipment. The method comprises the following steps: allocating E-HICH for the user by the network side; determining signature sequence groups according to the congruent relationship between the pre-configured E-PUCH physical resources and the signature sequence groups or between the E-PUCH physical resources and the signature sequences when carrying out feedback on non-scheduling transmission or semi-persistence scheduling transmission of the user; and using the signature sequence groups to code the feedback information according to the coding mode used when carrying out feedback on non-scheduling transmission, loading the coded feedback information on E-HICH and transmitting the coded feedback information. The invention can increase the number of users of HSPA+ system support.

Description

technical field [0001] The invention relates to communication technology, in particular to a feedback information transmission method, system and equipment. Background technique [0002] HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access) is an uplink enhancement scheme proposed by 3GPP (Third Generation Partnership Project, third-generation mobile communication partner project), through code channel resource, power resource sharing and other strategies To maximize uplink throughput. [0003] HSUPA data transmission is divided into scheduled transmission and non-scheduled transmission. The process of scheduling transmission is as follows figure 1 Shown: [0004] a. There is uplink enhanced data waiting to be sent in the UE cache, and the UE sends E-RUCCH (E-DCHRandom access Uplink Control Channel, E-DCH random access uplink control channel) to request scheduling resources; [0005] b. The base station performs resource scheduling according to the...
