    • A user terminal (115, 200) for a wireless communications system, equipped with at least two antennas (205, 206, 207) for the reception and/or transmission of traffic from a higher node (105). The user terminal (115, 200) is arranged to receive (210) said traffic in one or more data streams (S1, S2) i.e. with a rank of one or higher. The user terminal is arranged (215, 216, 220) to choose with which rank the higher node (105) should transmit the traffic to the user terminal (115, 200) on, and to also signal this choice to the higher node (105). The user terminal (115, 200) is arranged to base its choice of rank on the estimated received data rate at the user terminal for different transmission ranks, the estimated power consumption in the user terminal for different transmission ranks and the Signal to Noise ratio, SIR, of the channel at the UE.

    • The present invention relates to a method and arrangement for triggering a Random Access Channel (RACH) procedure for requesting uplink resources on a random access channel to a radio base station (600) scheduler based on a change in terminal (700) buffer status as compared to a Buffer Status Report BSR stored in said terminal. In a first method step, the status of the present terminal buffer content, i.e. terminal buffer data, is compared with the status of said stored buffer status report BSR. A second method step involves initiating a RACH procedure for indicating a service request to said base station scheduler upon detecting a change of buffer status at said comparison. The service request includes an indicator of the status change as a trigger for said scheduler to assign uplink resources to said terminal.
    • 本发明涉及一种用于触发随机接入信道(RACH)过程的方法和装置,用于根据比较的终端(700)缓冲器状态的变化,向随机接入信道请求上行链路资源给无线基站(600)调度器 到存储在所述终端中的缓冲器状态报告BSR。 在第一方法步骤中,将当前终端缓冲器内容(即终端缓冲器数据)的状态与所存储的缓冲器状态报告BSR的状态进行比较。 第二方法步骤涉及在检测到所述比较时缓冲器状态的改变时启动用于向所述基站调度器指示服务请求的RACH过程。 服务请求包括作为所述调度器向所述终端分配上行链路资源的触发的状态改变的指示符。
