Embodiment Construction

[0118] In order to make the purpose and technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0119] The implementation process of the method part of the present invention is given below by taking the HSUPA technology of LCR TDD as an example.

[0120] figure 1 For the implementation process of the present invention, each step is described as follows:

[0121] Step A: the base station and the terminal respectively establish a HARQ entity for each available carrier of the terminal, and the HARQ entity is responsible for managing the HARQ process corresponding to the carrier.

[0122] The multi-carrier TDD uplink HARQ process management method provided by the present invention is to allocate a corresponding HARQ process for each carrier that may be used by the UE. The HARQ processes of different carriers are independent of each other. The carrier used by th...

Abstract

The present invention discloses a hybrid automatic retransmission method of multi-carrier high-speed uplink grouping access, and comprises the following steps: A, the base station and the terminal respectively build a hybrid automatic retransmission request HARQ entity for each usable carrier of the terminal; the HARQ entity is responsible for managing the HARQ process corresponding to the carrier; B, the network side distributed uplink resources for the terminal; and C, the terminal assembles data packets according to the uplink resources distributed by the network side, determines the used carrier of each data packet, and adopts the HARQ entity corresponding to the carrier to select the HARQ process. The present invention also discloses a system and a terminal, which are used for realizing the hybrid automatic retransmission of the multi-carrier high-speed uplink grouping access. Thus the method leads to more flexible adoption of the HARQ process and more flexible data transmission, and can be used for the transmission of the multi-carrier high-speed uplink grouping data.

Description

technical field [0001] The present invention provides a HARQ process management method applicable to the uplink of a multi-carrier TDD system, which improves the efficiency and flexibility of data transmission by independently managing the HARQ processes of each carrier. Background technique [0002] The 3rd Generation Partnership Project (3rd Generation Partnership Proiect, referred to as "3GPP"), as an important organization in the field of mobile communications, has promoted the standardization of the 3rd Generation Mobile Communications (The Third Generation, referred to as "3G") technology, and its early protocol version Both uplink and downlink services are carried on dedicated channels. Among them, in Release 99 (Release 99, referred to as "R99"), the uplink and downlink data transmission rates that can be achieved are both 384 kilobits per second (Kbps). [0003] In the existing 3GPP technical standards, regardless of FDD (Frequency Division Multiplexing) or TDD (Ti...
