摘要： An active session mobility solution for radio link protocol (RLP) in accordance with the present invention defines two RLP migrations states. A first state is defined as a forward-link RLP state and depicts the communication of data from a home agent to an access terminal in an IP network. A second state is defined as a reverse-link RLP state and depicts the communication of data from the access terminal to the home agent in the IP network. In one embodiment of the seamless active session mobility solution for RLP in accordance with the present invention, a two-stage RLP transfer process for the migration of the two defined states from a source to a target is implemented. In a first stage, the forward-link RLP state is transferred from a source to a target. In a second stage, frame selection and the reverse-link RLP are transferred from the source to the target.

摘要： The invention includes a method and apparatus for adjusting the transmit power of a base station. In one embodiment, the transmit power of a base station is adjusted using rate metrics. A method according to one embodiment includes adjusting a transmit power of a target base station based on a per-user rate metric associated with the target base station and at least one per-user rate metric associated with at least one other base station. The per-user rate metrics may be based on any base station metrics, such as average system throughput of the base station, aggregate cell capacity of the base station, and the like. The per-user rate metrics may be computed or estimated using feedback information from wireless user devices. In one embodiment, the transmit power of a base station is adjusted using other information, such as geographic distances between base station, signal strength measurements received at base stations from other base stations, and the like, as well as various combinations thereof. A method according to one embodiment includes obtaining non-feedback information and adjusting the transmit power of the base station using the non-feedback information.

摘要： A closed loop power control based on receiving a continuous quality feedback is described. A main reverse link (RL) pilot is controlled by the quality feedback of a substantially continuous delay sensitive traffic stream, such as Voice-over-IP (VoIP), when such a stream is enabled. When such a stream is not enabled, the quality of a continuous RL overhead channel is used to control the pilot power. At the same time, the Traffic-to-Pilot Ratios (TPR) of contemporaneously transmitted delay sensitive data streams are independently adjusted based on a quality feedback associated with each such data stream.
