摘要： A method and system for reverse link transmit beam-forming. One method comprises using a plurality of antennas at an access terminal to wirelessly transmit signals to one or more base stations; receiving an input indicating a reverse link signal quality at the one or more base stations; and adjusting at least one of a gain and a phase of a signal to be transmitted on one or more antennas. The input may be a reverse power control (RPC) value sent from one or more base stations or a measurement of the closed-loop pilot transmit power.

摘要： A system, method, and apparatus for providing venue-cast service in a wireless access network are disclosed. A local transmitter can request reservation of air link resources on the wireless access network for a venue-cast transmission. The local transmitter can receive a forward link signal with a timing reference for data transmitted on the wireless access network such as, for example, the forward link signal in an EV-DO network or a FLO-based media distribution system. Based on the timing reference, the local transmitter can transmit venue-cast information in a same frequency band as the forward link signal utilizing the reserved air link resources. Optionally, the venue-cast system can include a collocated network repeater and the local transmitter can synchronize its timing and transmit power to the forward link signal from the repeater.

摘要： The present disclosure describes methods and apparatuses for improved transport block decoding in devices capable of wireless communication, which may include user equipment and network entities. For example, the present disclosure presents methods and apparatuses for decoding a code block from a plurality of code blocks corresponding to a transport block, obtaining a reliability indicator that identifies a reliability of the decoding of the code block, comparing the reliability indicator to a reliability threshold, and determining whether to decode a subsequent code block from the plurality of code blocks based on the comparing. Furthermore, these methods and apparatuses may include determining not to decode at least one subsequent code block of the transport block where the comparing indicates that the reliability indicator is less than the reliability threshold. As such, device power is not unnecessarily consumed by decoding likely superfluous code blocks.

摘要： Timing acquisition may be performed without typical correlation computations by determining a power of a received signal at certain points in time and using the determined power to identify gaps in the received signal. By determining gaps in the received signal, frame timing may be estimated, particularly in time-division networks where the location of guard periods within a frame is known. Gap detection may thus be used for timing acquisition.

摘要： Embodiments disclosed herein relate to methods and systems for providing improved position-location (e.g., time-of-arrival) measurement and enhanced position location in wireless communication systems. In an embodiment, an access point may replace information (e.g., data) transmission by a “known” transmission (or “reference transmission”) at a predetermined time known to access terminals in the corresponding sectors. The access terminals may use the received reference transmission to perform a position-location measurement, and report back the measured information. The access point may also send a reference transmission on demand, e.g., in response to a request from an access terminal in need for a location-based service.

摘要： In one embodiment, a method for providing echo cancellation in a wireless repeater includes: adding the pilot signal to a transmit signal; receiving a receive signal being the sum of a remote signal, a feedback pilot signal and a feedback transmit signal; cancelling the feedback transmit signal from the receive signal using a currently available feedback channel estimate and generating a first echo cancelled signal; generating an updated feedback channel estimate using the first echo cancelled signal and the pilot signal as a reference signal; cancelling the feedback transmit signal and the feedback pilot signal from the receive signal using the updated feedback channel estimate and generating a second echo cancelled signal; and amplifying the second echo cancelled signal as the transmit signal. In another embodiment, the feedback pilot signal is cancelled from the first echo cancelled signal using the updated feedback channel estimate to generate the second echo cancelled signal.
