摘要： A communication network, and associated method, permitting wireless communication with a mobile unit in an indoor environment. Transceivers are positioned at spaced-apart locations and are coupled to a centralized, control device. The transceivers include transmitter portions and wideband receiver portions. Uplink signals transmitted by a mobile unit are received by receiver portions of transceivers within the range of the uplink signal. Downlink signals are generated by at least two transmitter portions of at least two transceivers. The control device controls selection of which transmitter portions and which receiver portions of the plurality of transceivers are utilized to effectuate two-way communication with the mobile unit. Control signals can also be transmitted by the transmitter portions of all of the transceivers such that a mobile unit positioned anywhere within the area of the communication network receives the control signals.

摘要： Method and systems for reporting and analyzing link quality for radiocommunications are described. Use of frame erasure information (e.g., frame erasure rate (FER)) is highlighted. Presentation of frame erasure information can be segregated on a per-connection or per-cell basis, in addition to system-wide output. Moreover, frame erasure information can be correlated with geographical location of a mobile, the mobile's handover status or the equipment type of the mobile station to provide the network operator with a better understanding of quality issues within the network.

摘要： A method of reducing interference in a cellular radio communication including performing a courtesy handover of a first call to another channel to reduce interference in a second call when the presence of the first call on the same frequency as the second call causes the interference in the second call. Also, a method of setting up a call which permits a retry to a macro cell when a channel of sufficient quality is not found in a micro cell.

摘要： A method for use in a receiver in a time division multiple access (TDMA) wireless communication system to determine whether a channel is occupied and whether the transmitter occupying the channel is internal or external to the system. The method comprises the steps of receiving a signal, on a channel determining that the channel is unoccupied when the signal strength of the channel signal is below a threshold, determining that the transmitter is internal to the system when the received signal is highly correlated to a signal that is known to contain the proper predefined field.

摘要： A cellular communication system has a plurality of cells and a plurality of channels. The plurality of channels includes a plurality of measurable channels for which interference can be measured in both uplink and downlink directions and a plurality of unmeasured channels for which interference are not made in both uplink and downlink directions. The measurable channels, designated probe channels, may be channels for use in a digital system. The unmeasured channels may be channels for use in an analog system, or broadcast channels. A method and apparatus for allocating the plurality of channels comprises initially organizing the plurality of channels into a plurality of channel groups, wherein each channel group includes at least one probe channel, and wherein at least one of the channel groups further includes at least one unmeasured channel. Then, each one of the cells performs an allocation routine comprising the steps of monitoring at least one of the channel groups by making and collecting uplink and downlink interference measurements only on the probe channel of each monitored channel group over a predetermined time period. Then, the collected uplink and downlink interference measurements are analyzed in accordance with an adaptive channel allocation strategy. Finally, a selected one of the monitored channel groups is allocated to the cell in dependence on the analyzed uplink and downlink interference measurements. In this manner, the unmeasured channels are also subjected to an adaptive channel allocation strategy.

摘要： A frequency allocation system automatically allocates which of select radio frequencies are to be used for wireless communication systems in a wireless office system having a plurality of transceivers using a pool of select radio frequencies. The system determines an interference level for each radio frequency. Radio frequencies having an interference level above a select threshold are abandoned. Remaining usable radio frequencies having the lowest interference levels are selected as allocated frequencies to be used as a pooled resource by any of the plurality of transceivers.
