Mitigating ghost signalling effects in radio systems

减轻无线系统中的幻影信令效应

Abstract

适于调度和接收来自小区中的用户实体UE的上行链路传输并且进一步向核心网转发与这种传输有关的数据的基站中的方法以及基站。基站适于针对传输时间间隔在控制信道(E-AGCH)上发送(506)绝对准许信号,从而允许用户实体在相应传输时间间隔(500)以准许的数据速率发送上行链路传输。所述方法包括以下步骤:针对传输时间间隔,在控制信道上,-如果绝对准许被调度(502),则发送(506)绝对准许;-如果绝对准许未被调度(502),则检查(504)小区中的至少一个UE是否被配置用于在控制信道(E-AGCH)上进行接收,并且如果不是这种情况,则抑制(508)发送(DTX);-如果绝对准许未被调度(502)并且小区中的至少一个UE被配置用于在控制信道(E-AGCH)上进行接收(504),则所述方法还包括以下步骤中的至少一个步骤:-发送(510)针对小区中非配置UE的绝对准许;以及-选择(514)小区中任意的配置UE;以及-向所选UE发送(511)先前以早先的传输时间间隔发送的绝对准许。
A method in a base station - and a base station, adapted for scheduling and receiving uplink transmissions from user entities, UEs, in a cell and further forwarding data related to such transmissions to a core network. The base station is being adapted for transmitting (506) an absolute grant signal on a control channel (E-AGCH) for a transmission time interval, for allowing a user entity to transmit an up-link transmission at a granted data rate on a corresponding transmission time interval (500). The method comprises the steps, for a transmission time interval on the control channel, of - if an absolute grant is scheduled (502), transmitting (506) the absolute grant; - if an absolute grant is not scheduled (502), investigating (504) whether at least one UE in the cell is configured for receiving on the control channel (E-AGCH), and if this is not the case, refraining (508) from transmitting (DTX); - if an absolute grant is not scheduled (502) and at least one UE in the cell is configured for receiving (504) on the control channel (E-AGCH). Moreover, the method comprises at least one of - the step of -transmitting (510) an absolute grant for a non-configured UE in the cell; and - the steps of -selecting (514) an arbitrary configured UE in the cell; and -transmitting (511) an absolute grant, which was previously transmitted at an earlier transmission time interval, to the selected UE.
