Embodiment Construction

[0022] Exemplary embodiments disclosed herein illustrate scheduling transmissions in a first direction between a central base station and subscriber stations, such as customer premises equipment, by using a scheduler associated with the central base station. Communications in a second, opposite direction between the central base station and the subscriber stations are scheduled by another scheduler associated with the subscriber stations. Using two different schedulers for the two different directions of communication reduces the communication delay at least in part because it eliminates any requests for handshaking between the subscriber stations and the central base station, which are used in such setups , that is, the central base station scheduler is responsible for scheduling all communications in both directions.

[0023] Exemplary embodiments describe a significant departure from previous communication setups, such as those used for WiMax communications, for example, wh...

Abstract

A wireless communication system is disclosed where a hub base station has an associated scheduler. Remotely located subscriber stations such as customer premises equipment devices each have their own associated scheduler in the vicinity of each device. The hub base station scheduler is responsible for scheduling communications in a first direction between the hub base station and the subscriber stations. Each subscriber station scheduler is responsible for scheduling communications in a second, opposite direction between the corresponding subscriber station and the hub base station. In one example, the schedulers associated with the subscriber stations are responsible for scheduling all backhaul or uplink communications from the subscriber station to the base station. A disclosed example is useful for WiMax communications.

Description

technical field [0001] The present invention generally relates to communications. More specifically, the present invention relates to wireless communications. Background technique [0002] Wireless communication systems are well known. Various types of wireless communications are currently available. One type of communication currently being developed is called WiMax. In a typical WiMax communication system, a WiMax central base transceiver system (BTS) communicates with multiple customer premises equipment (CPE) devices that are located remotely from the WiMax central BTS. For example, in many cases a CPE allows one or more users within a building to communicate via the air interface between the CPE and a WiMax central BTS. [0003] Various studies are underway to improve the performance of WiMax. There are several areas for improvement. One shortcoming or disadvantage associated with current WiMax configurations is that undesired delays are introduced, especially for...
