摘要： Methods and apparatus are disclosed for improving a precoder selection process in a wireless communications system. In a normal precoder selection process, a precoder is selected from a codebook based on channel state information estimated from received reference signals. In between two received reference signals, a subset of precoders is cycled through and each precoder in the subset is iteratively selected for use by a transmitter to precode transmit signals. The subset of precoders may be adaptively modified based on predefined criteria.

摘要： An access node is configured to adapt uplink power control procedures based on the device attributes of a wireless device. The device attributes may, for example be the mobility, energy profile, or characteristic traffic pattern of the wireless device. The adaptive uplink power control procedure may be used to minimize or reduce power consumption, to improve resource utilization efficiency, or to reduce interference levels.
