Embodiment Construction

[0018] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] The present invention provides an uplink ACK / NAK feedback method. figure 2 It is a flowchart of an uplink ACK / NAK feedback method according to an embodiment of the present invention, including the following steps S202 to S204.

[0020] Step S202, the network node uses the uplink ACK / NAK feedback timing set or a subset thereof to configure the uplink ACK / NAK feedback timing, wherein the uplink ACK / NAK feedback timing set includes one or more uplink ACK / NAK feedback timings, where the uplink ACK The / NAK feedback timing corresponds to the backhaul subframe one by one.

[0021] In step S204, the network node uses the configured uplink ACK / NAK feedback sequence to perform uplink ACK / NAK f...

Abstract

The invention discloses an uplink acknowledge character / non-acknowledge character feedback method and network node. The method comprises the network node uses the uplink acknowledge character / non-acknowledge character ACK / NAK feedback time sequence set and sub-set thereof to configure the uplink ACK / NAK feedback time sequence, the plink ACK / NAK feedback time sequence set comprises one or multiple uplink ACK / NAK feedback time sequences, the uplink ACK / NAK feedback time sequences are corresponding to return sub-frame configuration results one by one; the network node uses configured uplink ACK / NAK feedback time sequences to conduct uplink ACK / NAK feedback. The invention solves the problem in related technology that number of the return sub-frame configuration results is very large to reduce the complex degree and overhead.

Description

technical field [0001] The present invention relates to the field of communications, in particular to an uplink acknowledgment character / non-acknowledgement character (ACK / NAK) feedback method and a network node. Background technique [0002] As an emerging technology, relay technology has attracted more and more attention and is regarded as a key technology of B3G / 4G. Since future wireless communication or cellular systems require increased coverage and support for higher rate transmission, this poses new challenges to wireless communication technology. At the same time, the cost of system construction and maintenance is more prominent. With the increase of transmission rate and communication distance, the problem of battery energy consumption has become more prominent, and future wireless communication will use higher frequencies, resulting in more serious path loss attenuation. Through the relay technology, the traditional single-hop link can be divided into multiple mu...
