CONFIGURABLE DOWNLINK AND UPLINK CHANNELS FOR IMPROVING TRANSMISSION OF DATA BY SWITCHING DUPLEX NOMINAL FREQUENCY SPACING ACCORDING TO CONDITIONS

摘要

Transmission techniques using configurable channels for the downlink and/or uplink are described. In one aspect, the downlink channel and/or uplink channel may be independently selected for a terminal The terminal may establish a connection with a base station on default downlink and uplink channels. Another downlink channel and/or another uplink channel may be selected based on various factors such as channel quality, loading, and interference. The terminal would then switch to the new downlink and/or uplink channel for communication. In another aspect, the base stations broadcast sector information used by the terminals for communication and/or channel selection. The sector information may include various types of information such as the available downlink and uplink channels, the frequencies of the available channels, the loading on the available channels, and QoS information. The terminals may select a sector, a downlink channel, and/or an uplink channel based on the sector information.

1. A method comprising:
establishing a connection between a terminal and a current sector serving the terminal via a first frequency channel for a first link and a second frequency channel for a second link for utilizing frequency division duplexing; selecting a third frequency channel from multiple frequency channels available in the current sector for the first link, wherein the first frequency channel and the third frequency channel are in the same frequency band; and switching the connection between the terminal and the current sector to the third frequency channel for the first link while continuing to utilize frequency division duplexing and maintaining the connection between the terminal and the current sector via the second frequency channel for the second link, wherein the first, second, and third frequency channels are different from one another.
