摘要： Several advanced features in wireless network, such as multi-carrier operation, multi-RAT/multi-mode transmission, etc., may not be exploited to their fullest potential when uplink transmit diversity is used in conjunction with them. Several techniques described herein address these problems. An example method begins with the evaluation (610) of operating conditions for a mobile terminal transmitter and, based on the operating conditions, selectively activating or deactivating (620) multiple-antenna transmission by the mobile terminal. The operating conditions that are evaluated include,in some embodiments, the applicability of power backoff (maximum power reduction, or "MPR"), including whether Additional MPR (A-MPR) or power management MPR (P-MPR) are applicable. Other operating conditions that are evaluated may include uplink data rate requirements or limitations for the mobile terminal, and/or the actual or estimated status of the battery in the UE.

摘要： A user equipment, UE,(14) and a radio network node (12) can perform multiple input multiple output,MIMO,communication. The UE determines a precoder (50, 54) used in the radio network node for transmitting signals from multiple transmit antennas to the UE. Based on the determined precoder used, the UE determines receiver parameters (22, 60A, 60B) for receiving MIMO signals from the radio network node, and configures the UE to receive MIMO signals from the radio network node in accordance with the determined receiver parameters. The radio network node may provide information for transmission to the UE indicating the precoder used in the radio network node to permit the UE to determine a receiver configuration for receiving MIMO signals based on the determined precoder used by the radio network node.

The method also comprises averaging (830) interference measurements using the selected averaging scheme, and determining (840) CSI for a CSI report based on the averaged interference measurements. The disclosure also relates to a method in a network node for controlling the averaging and to the user terminal and the network node.

摘要： User Equipment, UE (30), in a wireless radiocommunication network (10) supporting Coordinated Multi-Point, CoMP, transmissions may autonomously adopt an assumption of the quasi co-located (QCL)status of two (or more) antenna ports that is different from the default QCL status defined or signaled by the network (10), in response to one or more estimates of certain operating parameter values. The altered QCL status assumption allows the UE (30) to correct parameter estimates more accurately, and/or to reduce complexity in the parameter estimation correction.

摘要： An automatic gain control (AGC) method and system for a radio receiver are proposed in which the ACG comprises two AGC loops; a first loop controlling signal gain in the analogue portion of the radio receiver, a second loop controlling gain in the digital domain after digitization of the received signal. The analogue AGC loop has a slower response time than the digital AGC loop. When applied to a multi-branch diversity receiver, each branch has its own digital AGC loop, but the analogue gain can be common to all branches, based on measurement of the analogue signal in each branch.
