Methods and apparatus for dynamically assigning time slots in a wireless communication system

摘要

A wireless communication system having a base unit and a plurality of remote transceiver units utilizes a dynamic time slot assignment scheme for channel access. The base unit receives and processes a channel access request message from a remote transceiver unit and prepares a channel measurement request message in response. If an M^th time slot of a time frame is available, the base unit sends this message in the M^th time slot and receives a message having channel measurement data in the M^th time slot of the next time frame. On the other hand, if the M^th time slot of the time frame is already reserved, the base unit sends the message in an N^th time slot of the time frame and receives a message having the channel measurement data in the N^th time slot of the next time frame. The base unit selects, based on the channel measurement data, an appropriate channel for communication for the remote transceiver unit. Continuing with use of the dynamic slot assignment, the base unit sends a message having a channel identifier associated with the selected channel and receives an acknowledgement from the remote transceiver unit in response.
