Abstract

The invention discloses a relay method and equipment. The relay method is applied to a half-duplex relay and comprises the following steps of: sending the same first symbol vector to relay equipment and receiving equipment in a first time interval; and sending a second symbol vector to the receiving equipment in a second time interval to ensure that the receiving equipment acquires the first symbol vector and the second symbol vector according to a third symbol vector received in the first time interval and a fourth symbol vector received in the second time interval, wherein the third symbol vector comprises the first symbol vector sent by the sending equipment, and the fourth symbol vector comprises the second symbol vector sent by the sending equipment and the first symbol vector forwarded by the relay equipment. Through the technical scheme, full rate transmission of the symbol vectors can be obtained in a half-duplex relay transmission system.

Description

technical field [0001] Embodiments of the present invention generally relate to the field of wireless transmission, and more specifically, relate to a relay method and equipment thereof. Background technique [0002] In R8 of 3GPP, the multimedia broadcast multicast service (MBMS) is typically deployed in two scenarios, ie single cell (SC) and multi-cell MBMS single frequency network (MBSFN) transmission. [0003] The use of relays has been proposed in related discussions to extend coverage, improve capacity, and improve message edge performance. A hot topic of discussion is half-duplex relaying. For the relay used in the FDD system, there are two typical resource allocation methods between the base station (e-NB) and the relay device. One is TD trunk and the other is FD trunk. The TD relay shares the same frequency resource in a time-division manner for reception and transmission, while the FD relay shares the same time resource in a frequency-division manner for recepti...
