Embodiment Construction

[0041] In the following description, for purposes of illustration rather than limitation, specific details such as specific system architectures, interfaces, and techniques are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0042] A mobile terminal (Mobile Terminal), also referred to as a mobile user (UE, User Equipment), mobile user equipment, etc., can communicate with one or more core networks via a radio access network (for example, RAN, RadioAccess Network). Terminals may be mobile terminals, such as mobile telephones (or "cellular" telephones) and computers having mobile terminals, such as portable, pocket, han...

Abstract

The invention discloses a transmission control method, a base station, a relay node and a communication system for a relay link. The transmission control method comprises the steps that: one pair or two pairs in the uplink/downlink sub-frame pairs is/are selected for the relay link transmission; configuration information including the selection result is generated and is then sent to a relay node; after receiving the configuration information, the relay node adjusts the access link timing of the user equipment (UE) attached to the relay node according to the receiving-to-transmission switch time (R-to-T switchtime) so as to make the access downlink timing hysteretic and the access uplink timing ahead. According to the technical scheme, the design complexity of a relay link channel is reduced and the resource utilization rate is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a transmission control method and system for a relay link. Background technique [0002] With the rapid development of wireless communication services, a new generation of mobile communication systems needs to be able to support all-IP (internetwork interconnection protocol, Internet Protocol) high-speed packet data transmission above 100Mbps (Mbps: Megabit per second), support high Terminal mobility, supporting high transmission quality, providing high spectrum efficiency, etc. In terms of wide-area coverage, due to shadow fading and building occlusion, the base station in the traditional single-hop network will not be able to cover every place. Therefore, a relay technology is developed to improve the coverage and capacity of the system. Realize wide-area continuous coverage, therefore, relay technology has received more and more attention. [0003] The relay technology refe...
