20100322291 | Control Signaling for Multiple Carrier High Speed Uplink Packet Access in Radio Frequency Communication Systems - Systems and methods for providing an efficient mechanism for transmitting information needed to receive a secondary carrier over an existing message protocol on a primary carrier for a multiple carrier capable communications terminal. The receiver terminal may receive, on a primary carrier, a message containing information including a timing offset and a cell identification for a secondary carrier, for example. The communications terminal may then correlate a receiver to receive the secondary carrier without the need for a separate synchronization signal on the secondary carrier. These embodiments result in additional efficiency in a communications system. | 12-23-2010 |
20130242827 | METHODS AND APPARATUSES FOR FACILITATING UPLINK MULTIPLE INPUT MULTIPLE OUTPUT SIGNALING - A method, apparatus and computer program product are provided for detecting multiple input multiple output communications. A method and apparatus may enable transmission of a first control signal to a communication device. The first control signal may indicate at least one number of data streams that the communication device is allowed to utilize to transmit data. The method and apparatus may perform detection of discontinuous transmission on one or more control channels indicated by the first control signal. The method and apparatus may determine whether the communication device currently communicates on the control channels in response to performing the detection of the discontinuous transmission. | 09-19-2013 |
20140206330 | MEASUREMENT REPORTING - Measures for use in measurement reporting in a cellular telecommunications network. One or more configuration parameters for configuring a plurality of Cell Individual Offset (CIO) values for use in measurement reporting in a given cell are generated. Signalling information comprising the generated configuration parameters for the plurality of CIO values is transmitted to at least one user equipment in the given cell. | 07-24-2014 |
20140369277 | Method and Apparatus for Communication Using a Shared Uplink Wireless Communication Channel - A method of transmitting data by a user equipment using a shared uplink wireless communication channel is described. The method includes receiving a power grant corresponding to the allowed transmission power on the shared uplink wireless communication channel. Also, the user equipment receives a scheduling grant corresponding to whether transmission is allowed on the shared uplink wireless communication channel. The user equipment transmits data on the shared uplink wireless communication channel according to the power grant and the scheduling grant, wherein the power grant is received separately from the scheduling grant. A corresponding method of controlling transmission, apparatus and computer program product is also described. | 12-18-2014 |
20150092669 | Enhanced Scheduling Information Transmission - In a heterogeneous network environment where both high and low power nodes are sharing the same channel/frequency, explicit signaling in a downlink control message is used to select whether scheduling information SI is to be transmitted by a user equipment UE with a data payload or without a data payload. For the case where the selection is that SI is to be transmitted with a data payload, the downlink control message is used for the UE to select a transport format combination TFC for transmission of the SI with the data payload. Else for the case where the selection is that SI is to be transmitted without a data payload, the downlink control message is used for the UE to select transmit power for the transmission of the SI without the data payload. | 04-02-2015 |
20150094112 | Power Control to Compensate Interference Level Changes - A user equipment (UE) determines a first transmission power for a control channel using closed loop power control with a wireless network; and determines a second transmission power for the control channel. For transmission time intervals (TTIs) in which the UE is transmitting the control channel and also transmitting data on a data channel, the UE selects the second transmission power for transmitting the control channel. For TTIs in which the UE is transmitting the control channel but not also transmitting data on the data channel, the UE selects the first transmission power for transmitting the control channel. Three distinct embodiments are shown for these two transmission powers, and also quantitative data is shown that in a HSPA system this technique reduces inter-user interference at least at high SINR. | 04-02-2015 |
