Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for controlling transmission power of a base station in soft handoff.
SOLUTION: Transmitters 20, 32 are attached to a separated control unit 12 through communication links. The control unit 12 then derives the most likely command stream to be sent to a base station. In a second exemplary embodiment, the control unit periodically receives the final or average transmission level in a period and an aggregate quality measure for the feedback during a period from each of the transmitters. The control unit 12 determines the aligned power level and transmits a message indicative of the aligned power level to the transmitters. In a third exemplary embodiment, the transmitters 20, 32 send a message indicative of the transmission power of transmission to the receiver. The control unit 12 determines the aligned transmit power, based on the current transmission power.

Abstract: Methods, systems, and devices for wireless communication are described that provide for uplink common burst symbol waveform selection and configuration. A waveform for the uplink common burst symbol may be selected to be a single-carrier frequency division multiplexing (SC-FDM) waveform, an orthogonal frequency division multiplexing (OFDM) waveform, or combinations thereof, based at least in part on information that is to be transmitted. A pattern for SC-FDM sequences may be selected to provide enhanced channel estimation through common pilot tones across different sequences, wideband or narrowband sequences may be selected based at least in part on information to be transmitted, and acknowledgment feedback may be transmitted in an end portion of the uplink common burst symbol in some cases to provide additional processing time for determining the acknowledgment feedback.

Abstract: A data structure for managing user equipment communications in a wireless communication system is presented. In some examples, the data structure may include one or more resource element blocks into which a frequency bandwidth of a downlink channel is divided within a symbol that defines a transmission time interval in a downlink subframe. Furthermore, the data structure may include a control region and a data region within at least one resource element block of the one or more resource element blocks. Additionally, the data structure may include a downlink resource grant, located within the control region, for a user equipment served by the downlink channel. In an additional aspect, a network entity and method for generating the example data structure are provided.

Abstract: Standalone MBSFN cells may provide an improved user experience for an individual with a non-legacy UE since the bandwidth of that cell is mostly allocated to broadcasting streaming services. However, an individual with a legacy UE may be able to detect cell acquisition information associated with a standalone MBSFN cell but not to acquire standalone MBSFN cells. In order to solve this problem, the present disclosure provides various UE avoidance schemes that enable non-legacy UEs to acquire a standalone MBSFN cell and prevents legacy UEs from trying to acquire a standalone MBSFN only cell. The apparatus may receive cell acquisition information associated with an eMBMS standalone cell. The apparatus may detect a UE avoidance scheme based on a characteristic associated with the cell acquisition information. The apparatus may perform cell acquisition with the eMBMS standalone cell based on the characteristic.

Abstract: Techniques to detect for DTX frames in a "primary" transmission that may be sent in a non-continuous manner using a "secondary" transmission that is sent during periods of no transmission for the primary transmission. The primary and secondary transmissions may be the ones sent on the F-DCCH and Forward Power Control Subchannel, respectively, in an IS-2000 system. In one method, a determination is first made whether or not a frame received for the primary transmission in a particular frame interval is a good frame (e.g., based on CRC). If the received frame is not a good frame, then a determination is next made whether the received frame is a DTX frame or an erased frame based on a number of metrics determined for the primary and secondary transmissions. The metrics may include symbol error rate of the received frame, secondary transmission (e.g., PC bit) energy, and received frame energy.
