    摘要： A reference signal management (RSM) program executing on a mobile device detects multiple reference signals, allocates those reference signals into groups, and performs reference signal management functions using information conveyed in the reference signals. The RSM program detects both broadband and narrowband reference signals and maintains updated groups of reference signals that are transmitted from access points with independent configurations or different radio technologies. Battery power of the mobile device is efficiently used to manage reference signals in heterogeneous network environments by preventing unnecessary handoffs, overhead downloads, access probes and new registrations. Reference signals are managed from both synchronous and asynchronous sectors and in idle mode as well as in connected state mode. The RSM program performs functions such as managing handoffs between access points, managing an idle mode of the mobile device, managing an active group of the detected reference signals, and collecting overhead parameters for the mobile device.

    摘要： In embodiments, a first wireless device generates symbols for transmission to another wireless device. Adaptive power control is applied to the transmissions, for example, at symbol or frame boundaries. When a transmit power gain adjustment exceeds a threshold, all or part of the gain adjustment may be performed on the generated symbols before the symbols are combined in an overlap-and-add process. Part of the gain adjustment may also be performed through adjustment of the power amplifier. When the gain adjustment does not exceed the threshold, all of the gain adjustment may be performed through adjustment of the power amplifier. Performing gain adjustment before the overlap-and-add process results in a lower spectral spread of the transmitted waveform and improved bandwidth utilization efficiency. In embodiments, the power adjustment techniques are used in FDD/OFDM systems or other systems where a plurality of symbols or frames is transmitted substantially continuously.

    摘要： A method, an apparatus, and a computer program product operable in a wireless communication system are provided in which an access probe is generated for transmission to a wireless node. A first signal is generated for transmission to the wireless node. The first signal includes information corresponding to a first preferred beam pattern from the wireless node to the apparatus. A second signal is received from the wireless node including information corresponding to a second preferred beam pattern from the apparatus to the wireless node. The second preferred beam pattern is determined based on the access probe. The apparatus communicates with the wireless node using at least one of the first preferred beam pattern or the second preferred beam pattern.

    摘要： In a first aspect, an aggregated packet (A-MPDU) includes packets (MPDUs) and EC-Blocks (Error Correction Blocks) containing error correction coding information. A transmitter uses a Fountain coding scheme (for example, Raptor or RaptorQ) to generate the error correction coding information from the MPDUs. If a receiver detects an error in a received MPDU, then the receiver uses the error correction coding information from the EC-Blocks to correct the error. In a second novel aspect, a determination is made as to whether a change in error rate is more likely due to collisions or to a low SNR. If the determination is that the change is due to collisions then the MCS index is adjusted to restore a target error rate, whereas if the determination is that the change is due to a low SNR then the number of EC-Blocks per A-MPDU is adjusted to restore the target error rate.

    摘要： Various methods and apparatuses for transmitting an allocation of time in a wireless communication system are disclosed. In one aspect, an allocation of time for receiving communications via a receive beam direction is transmitted. The allocation of time may be based on information regarding an apparatus known to be located in the receive beam direction. A unique time for receiving communications from each known apparatus may be allocated, or a duration of time for receiving communications from the known apparatuses may vary based on a number of apparatuses known to located in a receive beam direction.
