Abstract: An exemplary method includes communicating an indication corresponding to at least a length of time it should take to reactivate a cell from an energy savings level corresponding to the indication to a fully activated state, and placing the cell into the energy savings level corresponding to the indication. Another method includes selecting an energy savings level for a cell, the energy savings level corresponding to a length of time it should take to reactivate the cell from the energy savings level to a fully activated state, and communicating to the cell an indication corresponding to at least the length of time it should take to reactivate a cell from the selected energy savings to the fully activated state. Apparatus and program products are also disclosed.

Abstract: A wireless communication system employs a wireless network element (104) and at least one remote wireless unit (102) that employ an air interface resource reservation and negotiation scheme. In one embodiment, the remote wireless unit (102) includes a processing device (106) operatively coupled to a radio frequency transceiver (108), that outputs an air interface reservation resource request (122). The air interface reservation resource request (122) includes one or more air interface resource reservation parameters (115). The air interface resource reservation parameters (115) are used to define a future time that is reserved by the wireless network element (104) for the remote wireless unit (102) so that suitable air interface resources are available at a defined future time.

Abstract: The present invention provides a method and apparatus for backhauling data in a communication system (100). A plurality of quality metrics are received at a centralized controller (105) from a plurality of base stations (101-104). The quality metrics are related to a data frame transmitted to the base stations (101-104) from a remote unit (113). A preferred data frame is determined from among the data frames. The centralized controller (105) then signals the base station associated with the preferred data frame to send the preferred data frame to the centralized controller.

Abstract: A method for updating power control at a base transceiver station in a communication system is provided. A base transceiver station transmits a signal frame. A mobile station receives the signal frame. The mobile station determines whether the signal frame was accurately received and sets a metric bit in a quality metric. The metric bit indicates whether the signal frame was received correctly by the mobile station. The mobile station transmits the quality metric, which is received by the base transceiver station. It is then determined whether to update power control, the determination based at least in part upon the quality metric.

Abstract: A communication system (101) concentrates the output of variable rate transcoders (XCDRs 203, 206, 209) to realize an increase in T1 Megastream link capacity. Line interface cards (212, 213) multiplex a generic transcoder/rate adapter unit (GTRAU) format to a concentrated transcoder/rate adapter unit (CTRAU) format based on a determined rate of the data being output from the variable rate transcoders (XCDRs 203, 206, 209). An increase in T1 Megastream link capacity is realized by efficiently concentrating full, half, quarter, and eighth rate channels into a single DS0 for transmission over the T1 Megastream.

Abstract: A differential coherent modulation and demodulation method and apparatus non-coherently modulates (201) a data stream to generate non-coherently modulated data. The non-coherently modulated data is phase modulated (215) with a supplementary signal (211) to generate coded data. The coded data is then transmitted. A receiver (301) then receives the coded data. A non-coherent demodulator accepts the received coded data as input and demodulates the coded data to provide the original data and the supplementary signal (327).
