    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： 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.
