    Abstract: A method, system, and components for outer loop power control (500) particularly useful for non-real time data services uses data transmitted in many short bursts of short duration, called Temp-DCH allocations (509). A target metric, preferably target SIR (502), is adjusted with differing step up and step down target metric adjustments. The initial target SIR (502) and the transient step size for target SIR adjustment (505-507) is determined in a dynamic way in the outer loop power control for each Temp-DCH allocation (509) of non-real time data.

    Abstract: A peer-to-peer communication system using a direct link setup (DLS) is disclosed. A mobile station (STA) establishes a direct communication link with another STA by sending a message requesting a DLS to an access point (AP), (i.e., a centralized controller). The AP may accept or reject the DLS request based on channel measurements. If the DLS request is accepted, the DLS is established such that the STAs may directly communicate with each other. An established DLS connection may be torn down by the AP sending a message including a DLS teardown request to one of the STAs, or based on channel measurements. The system may be an Ad hoc network comprising a plurality of STAs without an AP where each STA maintains a database of one-hop and two-hop STAs, and establishes a direct link to other STAs after informing neighboring STAs of an intention to establish a direct communication link.

    Abstract: A station (STA) comprising: a transmitter configured to transmit information to an access point (AP); a receiver configured to receive, from the AP, a management frame that includes an indication of an assigned group; wherein the transmitter is further configured to transmit, to the AP, an acknowledgement associated with the management frame; wherein the receiver is further configured to receive a data frame, wherein the data frame comprises a data packet and a group identifier; and a processor configured to determine whether the group identifier received in the data frame corresponds to the assigned group, and wherein the processor is further configured to cause the STA to enter a power saving mode on a condition that the group identifier received in the data frame does not correspond to the assigned group.
