Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0045] In the LTE system, the frame structure needs to meet the following requirements:

[0046] (1) PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) vs. PHICH (Physical HARQ Indication Channel, Physical Hybrid Automatic Repeat Indication Channel), that is, UE sends PUSCH in subframe n, and will receive it in subframe n+k accordingly PHICH, where k is the ACK / NACK feedback interval of uplink data, k=4 in LTE FDD R8; the content of the PUSCH includes at least the uplink data sent by the UE, and the content of the PHICH is the ACK for the data in the PUSCH sent by subframe n (Acknowledgment, confirmation) / NACK (Nonacknowledgement, denial) feedback.

[0047] (2) UL (Uplink, uplink) HARQ (Hybrid Automatic Repeat Request, Hybrid Automatic Repeat Request) PUSC...

Abstract

The embodiment of the invention discloses a relay transmission method and a network node. The relay transmission method comprises the following steps of: receiving configuration information of a relay link subframe which is configured in a subframe taking an integral multiple frame as a cycle and has a specific mixed automatic retransmission HARQ time sequence; and performing relay link transmission according to the relay link subframe. In the embodiment of the invention, when the relay transmission is performed according to the selected relay link subframe, the method and the network node satisfy various constraints of an LTEFDD system, and can be backwards compatible with UE in the existing LTE system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a relay transmission method and a network node. Background technique [0002] With the progress of society and the development of wireless communication technology, there is a higher demand for communication speed and communication quality. Wired transmission meets this requirement to a certain extent. However, wired transmission objectively requires operators to lay optical cables or rent wired resources, which undoubtedly restricts the use of wired transmission. The use of relay (relay) as wireless backhaul transmission has attracted great attention in the industry in recent years. The relay technology can expand cell coverage, increase cell capacity, and equalize cell throughput. [0003] The frame structure of the LTE system takes a frame (frame) as a unit, and each frame has 10 subframes (subframes), and each subframe is fixed at 1 ms. Due to the evolution of LTE to...
