    • The present disclosure provides an apparatus (30) and method (100) for advantageously simplifying joint detection processing in one or more demodulation stages (62) of a multi-stage receiver (34) by configuring at least one stage (62) to use a constrained multi-user search, such as a (constrained tree search. For example, a multi-stage receiver (34) includes at least two stages (62-1, 62-2) configured to successively process a received composite signal (40) that includes signal contributions (42-1, 42-2) from two or more "users" (46), which, for example, means that the received signal. (40) includes two or more symbol streams, in a non-limiting example,, particular embodiments of the present invention combines constrained tree searching with Serial Localized Indecision (SLIC) processing in a multi-stage receiver (34), where each stage (62) includes a joint processing unit (82). At least one of those stages (62) is configured to use a constrained multi-user search, rather than a full search, for jointly detecting symbols (44) in the stage input signal (66).

    • A signaling mechanism informs a Radio Network Controller (700) of the radio access technology associated with data packets forwarded to the Radio Network Controller (700) from base stations (600) supporting multiple radio access technologies. With this information, the Radio Network Controller (700) can associate received data with the corresponding radio access technologies, and thus manage differing physical layer procedures, such as outer-loop power control, for the radio access technologies. In an example method, first and second data units transmitted by a mobile station over first and second radio access technologies, respectively, are forwarded (430) from one or more base stations to a network control node for further processing. A control message associated with at least some of the data units is also sent (440) to the network control node, the control message indicating the radio access technology over which the associated data units were transmitted.

    • Teachings herein offer reduced-complexity coordinated multipoint (CoMP) reception of an uplink signal transmitted by a mobile terminal. The teachings obtain, for each sector antenna in a set of sector antennas deployed in a CoMP cell, a signal strength measurement of one or more downlink signals received by the mobile terminal from a sector associated with that sector antenna. The teachings compare the signal strength measurements and then select from the set, based on that comparison, a subset of sector antennas, for CoMP reception of the uplink signal B) using a subset of sector antennas for CoMP reception, instead of all sector antennas in the set, the teachings i educe the computational complexity of CoMP reception Moreover, the teachings in some embodiments minimize any performance degradation possibly resulting from performing CoMP reception with a reduced number of antennas, by selecting the subset to include sector antennas having the strongest signal strength measurements.
