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 each user is assigned a different signature sequence group or E-HICH, 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, which will affect the throughput of the system

Embodiment Construction

[0044] 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.

[0045] In the feedback information transmission method of the embodiment of the present invention, the network side assigns an E-HICH of the scheduled transmission type to the user and notifies the user that when feedback is performed for the user's non-scheduled transmission or semi-persistent scheduled transmission, the non-scheduled transmission The feedback method carries the corresponding feedback information on the E-HICH of the scheduled transmission type, so that the feedback information of non-scheduled transmission or semi-persistent scheduled transmission and the feedback information of scheduled transmission can be on the E-HICH of the same scheduled transmission type Transmission, so that scheduled t...

Abstract

A method, a system and a device for transmitting feedback information are provided. The method involves that the network side allocates an enhanced dedicated channel hybrid automatic repeat request acknowledgement indicator channel (E-HICH) for a scheduled transmission type to a user and informs the user (301). When an unscheduled transmission or a semi-persistent scheduled transmission of the user is fed back, the corresponding feedback information is borne in the E-HICH of the scheduled transmission type according to the feedback manner of the unscheduled transmission (304).

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...
