摘要： A broadband cellular network (BCN) provides a user equipment (UE) access to TVWS resources. The BCN authorizes the UE to access TVWS resources by conveying a mobile device identifier received from the UE, and a cell identifier associated with the UE's coverage area, to a Federal Communications Commission (FCC)-certified Database and receiving, from the Database, and storing an FCC ID associated with the UE and a set of available TVWS resources. The BCN then conveys, to the UE via a broadband cellular technology, a channel resource information element (CRIE) that includes the cell identifier and identifies the set of available TVWS resources. Subsequently, the BCN re-authorizes the UE to access TVWS resources based on the stored FCC ID and without re-conveying the mobile device identifier to the Database. The BCN further utilizes broadband cellular technology procedures to provide a “virtual” contact verification signal (VCVS) to the UE.

摘要： A method and apparatus for a co-scheduler can mitigate UE-to-UE adjacent carrier frequency band interference by allocating three sets to a first user equipment uplink. Each set has at least one sub-carrier in a first frequency band, at least one uplink time period, and at least one transmission power parameter. The co-scheduler initially allocates the first set. The co-scheduler allocates the second set in response to detecting a second user equipment operating proximal to the first user equipment, and the second set differs from the first set in either at least one sub-carrier or at least one transmission power parameter. The co-scheduler allocates the third set in response to detecting that the second user equipment is no longer operating proximal to the first user equipment, and the third set differs from the second set in either at least one sub-carrier or at least one transmission power parameter.

摘要： A method (500) and apparatus for multi-radio coexistence has a victim user equipment (UE) that receives (515) a sequence of subframes at a first transceiver from a serving base station, measures (520) channel state on the subframes to obtain channel state measurements, determines (530) a high-low interference pattern based on the channel state measurements, and transmits (550) to the serving base station a report that includes an indicator related to the high-low interference pattern. The method can include the victim UE receiving (610) an aggressor reference waveform (ARW) from the second transceiver, determining (620) spatial characteristics of the second transceiver from the ARW, and configuring (630) its antenna system based on the spatial characteristics. The method can have the victim UE determining (640) second transceiver characteristics from the ARW and transmitting (650) information regarding the second transceiver characteristics to its serving base station.

摘要： A communication system is provided wherein a user equipment (UE) receives control information from a wireless network. The UE monitors control channel candidates using common reference signals (CRS) and monitors enhanced control channel candidates using demodulation reference signals (DMRS) when the UE is configured in a first transmission mode, such as transmission mode 9, for receiving a downlink shared traffic channel based on DMRS. The UE monitors control channel candidates only using CRS when the UE is configured in a second transmission mode, such as any of transmission modes 1-6, for receiving a downlink shared traffic channel based on CRS. The UE then receives downlink control information (DCI) in a subframe in one of the monitored control channel candidates or enhanced control channel candidates in the subframe.

摘要： A user equipment (UE) receives a signal comprising multiple resource blocks and configured for receiving a subframe comprising multiple time-frequency resources, the time-frequency resources comprising at least two control channel candidates. The UE determines a first control channel candidate of the at least two control channel candidates in the subframe, determines a first antenna port (AP) associated with the first control channel candidate, decodes the first control channel candidate based on the first AP, determines a second control channel candidate of the at least two control channel candidates in the subframe, determines a second AP associated with the second control channel candidate, and decodes the second control channel candidate based on the second AP, wherein the AP used for decoding the first control channel candidate is distinct from the AP used for decoding the second control channel candidate.
