摘要： A wireless terminal that supports operation on a first wireless technology and operation on a second wireless technology performs a first set of measurements on a received signal on first operating frequency of the first wireless technology, wherein the first set of measurements are performed during time periods that overlap time periods during which the wireless terminal transmits signals of the second wireless technology. The terminal also performs interference avoidance to avoid interference from transmissions of signals of the second wireless technology to reception of signals of the first wireless technology if the first set of measurements indicates interference due to transmission of signals of the second wireless technology by the wireless terminal.

摘要： A wireless communication user terminal includes a controller communicably coupled to a transceiver. The controller is configured to tune the transceiver to transmit on a narrowband uplink control channel within a wideband frequency resource. The uplink control channel includes a pair of uplink control channels separated within the wideband frequency resource wherein the pair of uplink control channels are each located within a corresponding PUCCH resource region. The controller is also configured to change a frequency location of at least one of the uplink control channels, within the corresponding PUCCH resource region, away from an edge of the wideband frequency resource.

摘要： There is provided a communication device and a base unit, and methods thereof, for determining control information. The communication device receives a control channel message associated with the communication device in a control region on a first carrier from a base unit. The communication device also determines a set of resources in a search space within the control region, attempts to decode the set of resources in the search space for the control channel message, and determines control information from the decoded control channel message. The base unit generates a control channel message comprising control information associated with the communication device, determines a set of resources in a search space within a control region, selects a subset of resources within the determined set of resources for transmitting the control channel message, and transmits the control channel message on the selected resources in the control region on a first carrier.

摘要： A wireless communication user terminal obtains uplink access configuration information on a physical downlink control channel (PDCCH) addressed to a plurality of user terminals by processing the PDCCH based on a first system information received from a base station on a physical broadcast channel (PBCH) and based on synchronization information. The terminal sends a signature waveform based on the uplink access configuration information, prior to receiving system information in addition to the first system information, whereby the signature waveform enables the base station to transition from a relatively low power operating mode to a relatively high power operating mode.

摘要： A joint soft output ML receiver that is able to reduce interference based on partial transmission information (i.e., without knowing the existence of other layers or other users and their modulation schemes) is described. In one implementation, the partial information based joint ML receiver can achieve performance that is similar to full information based joint ML receivers even when full information regarding the interfering UE is not available at the desired UE due to transparent Multi-user Multiple Input and Multiple Output (MU-MIMO) transmission (such as with TM 8 and TM 9 transmissions in EUTRA LTE).
