摘要:
Embodiments of user equipment and methods for improved uplink transmission power management and scheduling, are generally described herein. For example, in an aspect, a method of uplink power management is presented, the method includes determining whether a total desired transmission power exceeds a total configured maximum output power for a subframe. When the total desired transmission power exceeds the total configured maximum output power, the method includes allocating a minimum proactive power limitation to each serving cell, assigning a remaining power to one or more channels based on priority, and computing a total power assignment based on the allocating and the assigning.

In various embodiments of the invention, a relay station in a wireless communications network may communicate with one or more subscriber stations at the same time and/or on the same frequency that the associated base station is communicating with another relay station in the same network. This contrasts with the conventional technique of devoting one time period or frequency exclusively to communications between the base station and the relay stations, and devoting another time period or frequency exclusively to communications between the relay stations and the subscriber stations.

An embodiment of the present invention provides an apparatus, comprising a subscriber station (SS) operable to communicate with a base station (BS) and at least one additional subscriber station (SS) in a wireless metropolitan area network, wherein the at least one additional SS attempts to overhear a first message from the SS and piggy back a second message for the overheard message from the SS's uplink data to the BS with its uplink data.

Embodiments of a base station and methods for allocating uplink bandwidth using SDMA are generally described herein. In some embodiments, uplink bandwidth request messages are received on a bandwidth request contention channel from one or more subscriber stations. The uplink bandwidth request messages are generated by the subscriber stations by modulating pilot subcarriers of a randomly selected disjoint pilot pattern with a randomly selected orthogonal sequence. The base station allocates uplink bandwidth to the subscriber stations when the uplink bandwidth request messages are successfully detected and decoded. The base station uses an SDMA technique to determine channel responses based on the orthogonal sequences to detect and decode the uplink bandwidth request messages.

摘要:
A relay station, which is used to communicate between a base station and a subscriber station in a wireless communications network, may also be used to communicate between the base station and another base station in an adjacent network by having the relay station communicate a message to or from the other base station, either directly or through another relay station associated with the other base station. In some embodiments, relay stations in adjacent networks may be co-located, so that they can communicate with each other over a short high-speed link. In some embodiments this link may be suitable for direct digital communications rather than through modulated carrier signals.
