Definitions
- FIGURE 1 shows one embodiment of wireless cells ordered according to a pattern
- FIGURE 2 shows one assignment pattern
- Each BS can make new channel assignments from time to time so that for the most part the MSs remain assigned according to their relative strength even though they are moving.
- FIGURE 3 shows simulation 30 of high to low ordering paired with the low to high (graph 303) at the interfering BS as shown in FIGURE 2.
- Graphs 301, 302 and 303 represent the capacity distributions of the three strategies. For example, at the 25% point, this means 75% of all users enjoy capacities exceeding 4, 3 and 2.5 BPH respectively. Or looking the other way 25% of all users have capacity less than 4, 3 and 2.5 BPH.
- the results using 16 sub-carriers show increased bandwidth (theoretical capacity), i.e., a significant reduction in high interference events for a greater number of users over either the preference channel assignment method (graph 301) or random assignment (graph 302), all using 100% of the channels in both of the interfering cells. Note that using preference pairing (which can be a premium service available to select number of MSs) a higher capacity (graph 301) can be achieved, but for a lower number ofMSs.
- FIGURE 4 shows one embodiment 40 of a process for assigning channels in a wireless system.
- Process 401 controls requests for service from a MS (user) and process 402 optionally determines if the requesting user is a preferred user. If it is then process 403 assigns a channel according to a class of service or other identifying characteristic of the MS depending upon contractual arrangements with the user.
- process 404 determines relative signal strength, as discussed above, and process 405, following an assignment pattern as shown in FIGURE 2, assigns a proper channel in conjunction with processes 406, 407, 408 and 409 which check to be sure there is no prohibition on the use of certain channels (such as, for example, would occur if certain channels were to be maintained vacant).
- the allocated spectrum is divided into channels.
- a channel is defined as a portion (maybe all) of the allocated spectrum being used for a specified period of time.
- the inventive concepts apply to FDMA, TDMA, TD-CDMA, OFDMA or combinations there of.
