Abstract: This invention measures the propagation delay τ1 between the user equipment and a first cooperating unit and the propagation delay τ2 between the user equipment and a second cooperating unit. These propagation delays are used to compute a timing advance amount to the user equipment to enable coordinated multi-point reception. In a first embodiment one cooperating unit receives a function of the propagation delay, computes the timing advance amount and transmits a timing advance command to the user equipment. In a second embodiment a central unit performs these operations.

Abstract: A method of operating a long term evolution (LTE) communication system on a shared frequency spectrum is disclosed. A user equipment (UE) is initialized on an LTE frequency band. A base station (eNB) monitors the shared frequency spectrum to determine if it is BUSY. The eNB transmits to the UE on the shared frequency spectrum if it is not BUSY. The eNB waits for a first time if it is BUSY and directs the UE to vacate the shared frequency spectrum after the first time.

Abstract: Carrier aggregation allows concurrent transmission on multiple component carriers (CC) to increase the data rate. A user equipment (UE) device in a cellular network provides periodic or aperiodic channel state information of the DL channel to a base station (eNB) for each of the aggregated CCs. The UE receives two or more reference signals corresponding to two or more aggregated CCs from an eNB. The UE computes a plurality of channel state information (CSI) reports for each of two or more aggregated CCs derived from the two or more reference signals. The UE receives a positive CSI request from the eNB for a CSI report and transmits CSI feedback to the eNB comprising one or more CSI reports selected from the plurality of CSI reports.

Abstract: A method of operating a wireless communication system is disclosed. The method includes configuring a user equipment (UE) for carrier aggregation with N serving cells, where N is a positive integer. The UE is scheduled to receive downlink data from M of the N serving cells at a first time, where M is a positive integer less than or equal to N. The UE provides uplink control information (UCI) for only the M serving cells.

Abstract: A wireless transmission system included at least one user equipment and a base station. The base station is operable to form a downlink control information block, modulate the downlink control information, precode the modulated downlink control information, and transmit the precoded, modulated downlink control information on at least one demodulation reference signal antenna port to the at least one user equipment. The precoded, modulated downlink control information is mapped to a set of N1 physical resource block pairs in a subframe from an orthogonal frequency division multiplexing symbol T1 to and orthogonal frequency division multiplexing symbol T2.

Abstract: A method of mapping control information in a wireless communication system is disclosed (FIG. 5). The method includes forming a subframe (FIG. 3) having a bandwidth and having plural regions (302-306). A base station (eNB) determines a communication mode with a remote user equipment. The base station maps control information specific to the user equipment into a first region of the subframe (508). The base station also maps control information common to plural user equipments into a second region of the subframe (512). The subframe is transmitted to the plural user equipments (412, FIG. 4).

Abstract: Embodiments of the invention are directed to a cellular communication network that can determine whether communications between one base station-UE pair may interfere with another UE that is in the same cell or a different cell. The network identifies interference parameters associated with interference signals that may be received by a UE. The interference signals may be generated by the base station itself, such as communications with other UEs, or by a neighboring base station. The base station transmits the interference parameters to the UE. The UE receives the one or more parameters comprising information about signals expected to cause intra-cell or inter-cell interference. The UE then processes received signals using the one or more parameters to suppress the intra-cell or inter-cell interference.
