    Abstract: In one example, a wireless communication device adapted for multi-band operation includes a first antenna, a first diplexer configured to pass signals within first and second sets of frequency bands, first and second signal paths, wherein each signal path includes a set of notch filters tunable to attenuate a different frequency. The wireless communication device includes a second antenna, a second diplexer configured to pass the first and second frequency bands, third and fourth signal paths, wherein each of the third and fourth signal paths includes one or more notch filters tunable to attenuate a different frequency, and a transceiver coupled to each signal path.

    Abstract: An ethernet-based communication system is provided. The communication system comprises: a first unit configured to generate a reference clock signal by using an input first ethernet signal, multiplex the first ethernet signal and a second ethernet signal in response to the reference clock signal, and output the multiplexed ethernet signals; a second unit configured to generate the reference clock signal by using the multiplexed ethernet signals, separate the second ethernet signal from the multiplexed ethernet signals in response to the reference clock signal, and output the first ethernet signal; and a transmission medium for connecting the first and second units and transmitting the multiplexed ethernet signals from the first unit to the second unit.

    Abstract: Method and apparatus for reporting feedback information for multi-carrier operation are disclosed. For more effective support for the asymmetric traffic loads in the downlink, a wireless transmit/receive unit (WTRU) is configured with multiple carriers with an unpaired downlink carrier(s). The unpaired downlink carrier is an active downlink carrier that does not have a corresponding active uplink carrier. The WTRU reports feedback information for multi-carrier operation including feedback for the unpaired downlink carrier. For transmission of the feedback information for the unpaired downlink carrier, a feedback channel may be allocated on a distinct non-overlapping resource region on the uplink carrier so that the network may determine which downlink carrier the received feedback information is for based on the resource region. Alternatively, a different feedback channel may be allocated for the unpaired downlink carrier. Alternatively, the feedback information may be transmitted via medium access control (MAC) encoded feedback.

    Abstract: A base station for wireless network uses one or more MIMO channels having subchannels, to communicate with multiple user equipments, and allocates the sub channels to the user equipments. Different subchannels of a given one of the channels can be allocated to different user equipments. The ability to allocate sub channels individually rather than only allocating entire channels can enable higher data rates to be achieved. This is particularly useful for improving data rates at cell boundaries or sector boundaries, where the coverage is traditionally weakest. A user equipment can use subchannels from different MIMO channels from different sectors or from different base stations.
