Abstract: Transmitting non-polluting dummy pilot signals in a wireless communication network permits estimation of the downlink propagation channels between a number of joint transmitters and a lesser number of receivers. With fewer receivers than transmitters, loop back information from the receivers is not sufficient to determine the downlink propagation channels between the transmitters and receivers. For N transmitters and M receivers, (N?M) dummy pilot symbols are transmitted to facilitate downlink channel estimation. Each dummy pilot signal is transmitted to an imagined or dummy receiver that is virtually located such that its downlink channel coefficient vector is orthogonal to those of the real receivers. Transmit pre-filtering based on estimated propagation channels is applied to the information signals for the real receivers and to the dummy pilot signals. The extent to which the dummy pilot signals interfere at each receiver is an indication of mismatch between estimated and actual propagation channels.

Abstract: A method of reducing loading on backhaul communications links in a wireless communications system suppresses a portion of the upward flow of frame information for idle and/or erased frames in certain situations, such as when multiple ones of such frames are successively encountered. A radio base station abstains from sending a frame header to a BSC/ANC for second and following frames of the Idle type and/or the radio base station abstains from sending a frame header to a BSC/ANC for second and following frames of the Erased type. The header may also or alternatively be suppressed for an Idle frame immediately following a Good frame. The BSC/ANC in effect fills in the suppressed frame information in such situations, forwards appropriate indications of frame type to the frame selection algorithm.

Abstract: A self-adaptive algorithm to enforce fairness executes on nodes in an ad hoc wireless network. Each node is configured to measure or estimate the utilization of the RF channel in its neighborhood and then share this information with its neighboring nodes. In this way, the nodes learn about the traffic flows within their neighborhood and may determine the competing flows. Based on the information about the competing flows, each node then determines the fair share of RF channel usage. The fair share may be computed by dividing the total time that all competing flows use the RF channel by the number of competing flows. Traffic flows using more than the computed fair share of channel access are slowed down to allow more access to the RF channel for flows that are not getting their fair share.
