摘要： A method in a first wireless node (120) for transmitting a reference signal is provided. The first wireless node (120) operates in a wireless communications network (100). The first wireless node (120) transmits the reference signal from at least two transmit antennas of the first wireless node (120). The reference signal is transmitted with a phase between the at least two transmit antennas indicating a desired phase related to radio conditions for reception of a transmission from a first radio node (1 11) at the first wireless node (120). The reference signal is to be received and taken into account by one or more other radio nodes (1 12) in the wireless communications network (100), e.g. when scheduling transmissions to other wireless nodes (122).

摘要： In a multi-access system, an access selection principle is achieved by selecting a signal strength threshold level (130-133) based on a determined load level (U LOCAL ) in a first access network. A new user in an area commonly covered by more than one access network attempts to allocate to the first access network if an experienced signal strength exceeds the signal strength threshold level (130-133). Communication utility can preferably be maximised or at least be taken into account by using suitable load level dependencies. By increasing the threshold when the load level approaches the capacity limit, a completely filled first access network is avoided. This gives an opportunity to let particularly well-suited users still have access to the first access network. At the same time, since the preferred access is decided before the actual access attempt, control signalling can be significantly reduced, even at very high traffic loads.
摘要翻译：在多址系统中，通过基于第一接入网络中的确定的负载水平（U> LOCAL ）来选择信号强度阈值水平（130-133）来实现接入选择原理。如果有经验的信号强度超过信号强度阈值电平（130-133），通常由多于一个接入网络覆盖的区域中的新用户尝试分配给第一接入网络。通过使用适当的负载水平依赖性，通信实用程序可以优选地被最大化或者至少被考虑在内。通过在负载水平接近容量限制时增加阈值，避免了完全填充的第一接入网络。这给了一个机会让特别适合用户仍然可以访问第一个接入网络。同时，由于在实际访问尝试之前决定了优选访问，所以即使在非常高的流量负载下也可以显着地减少控制信令。
