摘要： Systems and methods for providing an efficient mechanism for transmitting interference vectors to communications terminals, such as user equipments (UEs), in an over the air radio telecommunications network with spatially multiplexed multiple user multiple input multiple output (MU-MIMO) capability. A new pre-coding information downlink channel is defined. Messages containing semi-persistent interference vector information for MU-MIMO user equipment are defined and transmitted over the new channel in a manner that allows infrequent transmission and efficient use of resources. Using the interference vectors and applying inter-user interference adaptation to received messages, the UEs may receive spatially multiplexed MIMO transmissions and actively remove inter-user interference after reception of the messages. Compression of the pre-coding vector information transmitted over the pre-coding information channel may result in additional increases in efficiency in the system.

摘要： Structure of a multi-carrier flexible spectrum wireless cell is determined from received synchronization or broadcast channels of detected individual carriers. The determined structure is used to select an intended carrier for initial access or cell reselection to the flexible spectrum wireless cell. The structure may have carriers compatible with an earlier version (LTE/Release 8) of a communication standard and with a later version (LTE-A/Release 9). The received synchronization channels can inform of: relative positions of the individual carriers in a spectrum band of the multi-carrier structure; relative timing alignments of the received synchronization channels; contents of the received synchronization channels; and/or layer 1 cell-carrier identifiers. The synchronization channels may have a different structure as between the earlier and later versions, and the different structure is used to select the carrier that is compatible with the user equipment making the selection.
