Method and apparatus for multi-sector transmission in a wireless communication network
First Claim
1. A method for transmitting data to a subscriber in a wireless communication network comprising:
- evaluating performance requirements associated with the data and prevailing network conditions; and
determining the number of per-sector data streams to be used for transmitting the data to the subscriber, and whether said per-sector data streams provide spatial multiplexing, spatial diversity, or some mix thereof, based on said evaluation.

Abstract
According to transmission control as taught herein, a transmission control system is configured for controlling the transmission of data via two or more data streams to a subscriber in a wireless communication network. In one or more embodiments, the transmission control system comprises a first control circuit to evaluate performance requirements associated with the data and prevailing network conditions, and a second control circuit to determine the number of per-sector data streams to be used for transmitting the data to the subscriber, and to determine whether the per-sector data streams provide spatial multiplexing, spatial diversity, or some mix thereof, based on the evaluation. Such operations may be applied to a variety of network types, including those that use per-sector shared packet data channels. In such cases, multi-sector transmission control may include transmission scheduling coordination across the involved shared channels.
