    Abstract: Systems and methods for multi-hop service discovery within a mobile device cluster are disclosed. A seeker station may be seeking or may have found a desired service available from a provider station. The seeker station may receive the service announcement from the provider station, and become a proxy station, expanding the service area of the provider station. The proxy station may selectively transmit services and advertisements for services on behalf of the provider station based on restrictions placed on selection as a proxy station. Restrictions or conditions may be placed on the proxy station limiting the number of stations that may become proxy stations, limiting traffic within the cluster. Some restrictions may require a proxy station to be a member of the cluster or a member of a group within the cluster. Selection as a proxy station and frequency of transmission of service announcements by proxy stations may also be conditioned on various specific parameters or combinations of parameters as specified by the provider station.

    Abstract: Techniques and apparatus for controlling the transmit power of an uplink (UL) signal from a user terminal in a wireless communications system in an effort to achieve some target characteristic, such as a target carrier-to-interference (C/I) ratio, at an access point (AP) are provided. In this manner, such a user terminal may help avoid or compensate for imbalances in received radio frequency (RF) power between UL signals received from multiple user terminals by the AP. For example, the transmit power at each user terminal may be controlled in an effort to achieve a target post-processing C/I ratio of 28 dB per spatial stream in an effort to reduce large power imbalances and optimize throughput per user terminal. The user terminal and the AP may compose part of a multiple-input multiple-output (MIMO) communication system utilizing spatial-division multiple access (SDMA) techniques.
