Abstract: A method and mechanism to reduce the energy consumption of a single-carrier wireless transmission system such as a base station or a subnet of multiple base stations in relation to the loading of the system. Energy savings may be achieved by withholding the transmission of the system over some time slots, decreasing the available frequencies for user traffic transmission, dynamically adjusting the system to a lower bandwidth, or a combination of these techniques in proportion to the system transmission load at a given time. The lower the system load, the more transmission resources may be withheld or reduced, and, hence, the more savings in energy consumption. Energy savings may be most prominent during periods of low traffic loading of the single carrier-based wireless transmission system.

Abstract: The present disclosure relates to an advanced digital baseband processor for a base station in a cellular communications network. In general, the advanced digital baseband processor integrates multiple Radio Access Technologies (RATs). As used herein, a RAT is a radio access technology as defined by a corresponding standard. For example, in one embodiment, RATs integrated by the advanced digital baseband processor include a Code Division Multiple Access (CDMA) voice RAT (e.g., 3GPP2 CDMA 1xRTT or 3GPP2 CDMA 1xAdvanced) as well as a CDMA Data Only, or Data Optimized, (DO) RAT (e.g., 3GPP2 CDMA EV-DO or 3GPP2 CDMA EV-DO Rev B). In another embodiment, the RATs integrated by the advanced digital baseband processor also include 3GPP Long Term Evolution (LTE). The RATs given above are only examples. The advanced digital baseband processor may integrate additional or alternative RATs.

Abstract: Overlay and underlay carriers are used to transmit traffic over a cellular network for a call associated with a mobile terminal. A method involves determining which one of the underlay carrier and the overlay carrier is to carry the traffic as a function of a resource parameter associated with a resource for transmitting the traffic and a mobility parameter of the mobile terminal. In some implementations, the method is applied at for example a base station to a plurality of calls associated with various mobile terminals within a cell and the calls are assigned to the underlay carrier and the overlay carrier using an optimization routine that optimizes a function associated with the capacity while imposing a constraint such as for example a constraint on a hand-off rate between the carriers.

Abstract: A method and apparatus for locating, in relation to a plurality of cell sites, a mobile cellular transceiver in a conversation state. The method includes the steps of transmitting from one of the plurality of cell sites to the mobile transceiver a handoff signal for causing the mobile transceiver to continually transmit a known beacon signal while still in the conversation state, at at least some of the plurality of base stations, receiving the known beacon signal and measuring the time at which the known beacon signal was received, and calculating the location of the mobile transceiver from the respective locations of each of the at least some of the plurality of cell sites and the respective times at which the beacon signal was received at each of the at least some of the plurality of cell sites.
