Embodiment Construction

[0048] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0049] A method for sending uplink HARQ feedback information provided by the present invention, such as image 3 As shown, it mainly includes the following steps:

[0050] In step 301, the terminal and the base station determine PHICH resources according to the index of the downlink component carrier where the PHICH is located, the group number of the PHICH, and the index of the orthogonal sequence in the PHICH group.

[0051] The PHICH resource in the present invention consists of OK, among them, is the index of the downlink component carrier where the PHICH is located, is the group number of PHICH, is the index of the orthogonal sequence in the PHICH group.

[0052] Among them, the parameter can be determined based on The principle is that the index of the downlink component carrier where the latest UL...

Abstract

The invention discloses a method of sending uplink hybrid automatic retransmission request (HARQ) feedback information; the method includes that: a terminal and a base station determine PHICH resource according to the index of downlink component carrier of physical hybrid retransmission indication channel (PHICH), PHICH group number and the index of orthogonal sequence in PHICH group; the base station transmits uplink HARQ feedback information based on determined PHICH resource. The invention also discloses a device for transmitting uplink HARQ feedback information and solves the transmissionproblem of uplink HARQ feedback information in advanced long-term evolution system (LTE-Advanced), and ensures LTE-Advanced terminal to operate normally in spectrum aggregation mode and enables the LET-Advanced to be compatible with LTE Release-8, and facilitates improving the scheduling flexibility and throughput of system.

Description

technical field [0001] The invention relates to a transmission technology of uplink hybrid automatic repeat request (HARQ) feedback information in wireless communication, in particular to a method and device for sending uplink HARQ feedback information. Background technique [0002] A radio frame (radio frame) in a Long Term Evolution (LTE, Long Term Evolution) system includes frame structures in a Frequency Division Duplex (FDD, Frequency Division Duplex) mode and a Time Division Duplex (TDD, Time Division Duplex) mode. The frame structure of FDD mode, such as figure 1 As shown, a wireless frame of 10 milliseconds (ms) consists of twenty slots (slots) with a length of 0.5ms and numbers 0 to 19, and slots 2i and 2i+1 form a subframe (subframe) with a length of 1ms i. The frame structure of TDD mode, such as figure 2 As shown, a 10ms radio frame consists of two half frames with a length of 5ms. A half frame includes five subframes with a length of 1ms. Subframe i is defin...
