摘要： A method in a network node (110) for configuring cells for downlink operations in a telecommunications system (100) is provided. The network node (110) is configured to support non-contiguous downlink operations on more than one cell (f1, f2, f3, f4) in at least one frequency band. The network node (110) receives a signal from a user equipment (121) in the telecommunications system (100). The signal comprises information about radio access capability of the user equipment (121). Information about radio access capability of the user equipment (121) comprises a first indication which indicates the maximum number of cells that is supported by the user equipment (121) in the non-contiguous downlink operation. Furthermore, the information about radio access capability of the user equipment (121) comprises a second indication which indicates the maximum gap bandwidth between cells (f1, f2, f3, f4) that is supported by the user equipment (121) in the non-contiguous downlink operation. Then, the network node (110) configures more than one cell (f1, f2, f3, f4) for a non-contiguous downlink operation supported by the user equipment (121) based on the first and second indication in the information about radio access capability of the user equipment (121). A network node (110), a method in user equipment and a user equipment (121) are also provided.

摘要： The present disclosure relates to a method for determining CSI in a user terminal of a wireless communication network. The method comprises receiving (810) information from a network node indicating at least one of a plurality of different averaging schemes, and selecting (820) one of the averaging schemes based on the received information. The plurality of different averaging schemes each defines a limitation regarding over which radio resources that averaging is allowed for interference measurements. 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： 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.
