Abstract:
Methods, a first user equipment (101), a serving network node (110) and an interfering network node (130) for managing assistance information are disclosed. The interfering network node (130) obtains (A010) assistance information including a set of temporary identities for a set (105) of second user equipments served by at least one cell (C2) operated by the interfering network node (130). The interfering network node (130) sends (A020) the assistance information to the serving network node (110). The serving network node (110) obtains (A030) the assistance information. The first user equipment (101) receives (A050), from the serving network node (110), the assistance information. The first user equipment (101) decodes (A060) information of a control channel, transmitted by the interfering network node (130), by means of the assistance information. The first user equipment (101) uses (A070) the decoded information in order to mitigate interference from said at least one cell (C2). Furthermore, computer programs and carriers therefor related to the aspects above are disclosed.

Abstract:
In a user equipment, a unified receiver structure may be specified as both an equalizer and a multi-user detector. That is, the receiver may transfer between an equalizer and a multi-user detector within the same structure. A received signal may be estimated using the combined equalizer and multi-user detector unit.

Abstract:
The present invention employs multiple antenna elements and signal combining techniques to achieve both antenna diversity and combining gain while suppressing interference. To obtain the maximum achievable diversity gain, the received signals at the antenna elements are adjusted for independent fading. With small latency, real time packet by packet beamforming is enabled for superior mobility.
