Problems solved by technology

If the same E-PUCH physical resources are allocated to multiple users, the same E-HICH cannot be used to feed back these users at the same time, thus causing the space separation technology to be unable to be applied to the HSUPA system

Embodiment Construction

[0059] 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 with reference to the accompanying drawings and embodiments.

[0060] The feedback method for sharing physical resources by multiple users according to the embodiment of the present invention utilizes space division technology in a transmission scheduling system to allocate the same E-PUCH physical resources to different users, so that these users share the E-PUCH physical resources. When multiple users sharing the E-PUCH physical resource feedback, use different orthogonal sequences to encode the feedback information corresponding to different users, and map the encoded feedback information to the same E-HICH for feedback to the corresponding users; or The feedback information corresponding to different users is encoded using the same orthogonal sequence, and the enc...

Abstract

The invention discloses a method, a system and a device for feeding back multi-user sharing physical resources, belonging to the technical field of communication. The method comprises the following steps: distributing the same E-PUCH physical resource for a plurality of users by a network side; confirming an orthogonal sequence corresponding to each user of a plurality of users according to the configuration information of the network side, wherein the orthogonal sequences corresponding to different users are different; after receiving uplink strengthening data transmitted by the users on theE-PUCH physical resource, coding the feedback information corresponding to each user by the orthogonal sequence corresponding to the user; and mapping the coded feedback information corresponding to the users to the same E-HICH and feeding back to the corresponding user. The invention can improve the use ratio of system resources as well as the uplink output.

Description

technical field [0001] The present invention relates to communication technology, in particular to a feedback method, system and device for sharing physical resources by multiple users. 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 Partnership Project). in order to maximize the upstream throughput. [0003] The data transmission of HSUPA is divided into scheduled transmission and unscheduled 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-DCH Random 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 received scheduling ...
