Problems solved by technology

[0011] The disadvantage of the existing technology is that in the current LTE-A system, after the RN receives the data sent by the NB, there is no corresponding technical solution to solve the problem of the RN feeding back ACK / NACK to the NB.

Embodiment Construction

[0042] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0043] image 3 A schematic diagram of the implementation process for the ACK / NACK feedback method, as shown in the figure, may include the following steps:

[0044] Step 301, RN receives TB sent by NB;

[0045] Step 302, the RN determines the ACK / NACK information to be fed back to the NB according to whether the reception of the TB is correct or not;

[0046] Step 303, RN sends ACK / NACK information to NB through uplink control channel.

[0047] Based on the same inventive concept, an embodiment of the present invention also provides a method for processing ACK / NACK feedback information, which is used to process the ACK / NACK information sent by the RN to the NB through the uplink control channel.

[0048] Figure 4 It is a schematic diagram of the implementation flow for the processing method of ACK / NACK feedback information, as shown in the figure, t...

Abstract

The invention discloses a method and equipment for feeding back and processing ACK / NACK information. The method comprises that: a trunk node receives a transmission block sent by a base station; the trunk node determines the ACK / NACK information fed back to the base station according to the receiving accuracy of the transmission block; and the trunk node sends the ACK / NACK information to the base station through an uplink control channel. The invention provides a technical scheme for solving the problem that the trunk node feeds back the ACK / NACK information to the base station after the trunk node receives the data sent by the base station in the current LTE-A system.

Description

technical field [0001] The invention relates to communication technology, in particular to a feedback and processing method and equipment for ACK / NACK information. Background technique [0002] The relay (Relay) transmission scheme in the LTE-A (LTE is the abbreviation of Long Term Evolution, which is the evolution system of the third generation mobile communication system, and the LTE-Advanced system is an upgrade of the LTE system) system is being researched and designed. , from the current research and discussion progress, the main design target is half-duplex and in-band (In-band) Relay. The so-called half-duplex means that the Relay node cannot simultaneously receive and transmit on the same frequency. The so-called in-band refers to data transmission between eNB (evolved base station) and Relay, data transmission between eNB and Macro UE (Macro UE, UE: User Equipment, user equipment), and data transmission between Relay and Relay UE (relay UE). UEs) use the same freq...
