Diversity set updating method and relay system

Abstract

The present invention discloses an updating method for diversity collection; an updating device for collection is arranged; the method comprises that a collection updating list of the MS diversity collection is formed; the collection updating device updates the MS diversity collection according to a collection updating list. With the method provided by the present invention, the updating method of diversity collection in the relay system is realized and the diversity collection technology can be fully implemented in the relay system. At the same time, the present invention also provides a relay system. The method, the device and the relay system provided by the present invention adopt collection updating device to control the MS diversity collection, which reduces the complexity and the cost of the anchoring station; moreover, the flow is simple which is beneficial to reducing the complexity of control. In addition, when the collection updating device is the anchoring station, novel collection updating body does not to be defined, which reduces the network entities and signal number and further reduces the occupancy of unused resources.

Description

technical field [0001] The invention relates to a diversity set technology, in particular to a diversity set update method and a relay system. Background technique [0002] In a wireless network, an MS is allowed to maintain uplink and downlink communication with multiple BSs at the same time to obtain diversity gain. The set formed by these BSs is called the diversity set of the MS. According to the diversity technology adopted, it can be divided into macro-diversity switching and fast base station switching. In macro-diversity handover, the MS communicates with all base stations in the diversity set at the same time, that is, in the downlink, all the base stations in the diversity set transmit the same signal to the MS at the same time, and in the uplink, all the base stations in the set Both receive the signal of the MS at the same time. In the fast base station switching mode, the system only selects one of the base stations with the best signal for actual sending and ...

Problems solved by technology

[0005] Although it can be applied in the relay system of the prior art, the prior art does not provide an updated technical solution for diversity aggregation in the relay system. Therefore, in order to realize the application of the diversity aggregation technology in the relay system, it is urgent to provide a An Updating Scheme for Diversity Sets in Relay Systems
