摘要： Configuring a peer-to-peer (P2P) link in a multi-access wireless network includes receiving P2P configuration information from a base station at a UE supporting P2P communication. The first UE communicates directly with a second UE based on the P2P configuration information received from the base station. The first UE may send a configuration request message to the base station, and receive a responsive configuration message with the P2P configuration information from the base station, which messages may be Radio Resource Control (RRC) messages supporting P2P. In the alternative, the P2P configuration information may be provided in a system information block (SIB) broadcast by the base station. The P2P configuration information may indicate allocation of physical layer or Medium Access Control resources, or both allocated for P2P communication, and other information.

摘要： Systems and methodologies are described that facilitate providing power control for intermediary access points in wireless networks, such as relay nodes. Parameters related to intermediary access point communications can be provided to a serving access point, and the serving access point can generate power adjustment values and related commands based at least in part on the parameters. The parameters can include load on the intermediary access point, signal-to-interference-and-noise ratio (SINR) and/or similar parameters related to communications between the intermediary access points and/or one or more UEs, etc. In addition, end-to-end power control can be provided where intermediary access points report SINR to serving access points allowing serving access points to adjust downlink transmission power.

摘要： Systems, methods and apparatuses for reducing HARQ retransmissions using peak power management techniques are presented. In one example, a receiver may perform multi-level error correction for reducing HARQ retransmissions. The receiver may include a Peak to Average Power Ratio Management Module (PAPR MM) decoder configured to perform a first level of error correction utilizing retransmissions originating at a front end of a distal transmitter. The receiver may further include a symbol demapping module connected to the PAPR MM decoder, a deinterleaver connected to the symbol demapping module, and a decoder connected to the deinterleaver and the PAPR MM decoder, where the decoder may be configured to perform a second level of error correction utilizing retransmissions originating at a back end of a distal transmitter. A transmitter for reducing HARQ retransmissions using PAPR techniques is also presented.

摘要： Configurations disclosed herein include systems, methods, and apparatus that may be applied in a voice communications and/or storage application to remove, enhance, and/or replace the existing context. Enhancing the context of a voice communication may first include suppressing an existing context component from the digital audio signal to obtain a context suppressed signal. This signal may then be mixed with a new context signal to create a context enhanced signal, which may then be encoded before transmission. When this new context enhanced signal includes a speech component, it may be encoded and transmitted at a particular bit rate. When the context enhanced signal does not include a speech component, it may also be encoded at a similar bit rate. However, depending on the state of a process control signal, portions of a digital audio signal that lack a speech component may also be transmitted at a lower bit rate.

摘要： A method and apparatus for performing spectral allocation for a wireless link in a wireless communication system is disclosed. The method determines a distance/range for the wireless link and assigns an optimal sub-carrier frequency to the wireless link based on (1) a higher frequency to lower frequency priority and (2) on the value of the distance/range of the wireless link and (3) on the presence or absence of a primary user in a spectrum of the wireless link. Higher frequency sub-carriers are assigned to wireless links that have a shorter distance/range and lower frequency sub-carriers are assigned to wireless links that have a longer distance/range. The method of the present work increases the spectral efficiency of the wireless communication system and improves system bandwidth.
