User group data service system and method based on relay millimeter wave system downlink

The invention discloses a user service system and method for a millimeter wave system downlink, and particularly relates to a relay and a relay-which are used for distributing and serving a new user according to a user group where the new user is located after a base station receives a service request of the new user. Frequency band for user communication. And then, the base station sends the dataand the frequency band information to a relay nearby a new user in a beam form. And after the relay receives the data, forwarding the data to a new user by using a single antenna. According to the invention, relay-is fully excavated; the space and frequency resources between the users meet the data service requirements of each user in the user group under the condition that the available bandwidth of each user is not reduced. 本发明公开了一种毫米波系统下行链路的用户服务系统及方法，具体的说是基站在接到新用户的服务请求后，根据新用户所处的用户群，分配服务该新用户的中继以及中继-用户通信的频段。然后，基站将数据和频段信息以波束的形式发送给新用户附近的中继。中继接收数据后，利用单天线将该数据转发给新用户。本发明充分挖掘中继-用户之间的空间和频率资源，在不降低每个用户的可用带宽情况下，满足用户群里每个用户的数据服务
