摘要： In order to provide better wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas that are configured to provide coverage at these different altitudes. The RAN may assign resources, such as transmit power or frequencies, to wireless coverage areas serving particular altitude ranges in a proportion that is commensurate with the number of WCDs being served by these particular altitude ranges. As a result, RAN and WCD performance may improve.

摘要： In order to provide better wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas that are configured to provide coverage at these different altitudes. The RAN may assign an initial transmit power to a particular WCD based on the particular WCD's altitude. For instance, if the particular WCD is above a threshold altitude, the RAN may set the initial transmit power to the WCD to a lower value. However, if the WCD is below the threshold altitude, the RAN may set the initial transmit power to the WCD to a higher value, to overcome low-altitude signal obstructions. As a result, RAN and WCD performance may improve.

摘要： A mobile station measures a pseudonoise (PN) offset and a signal strength of a spread spectrum signal transmitted by a given sector of a spread spectrum communication system. The measured PN offset differs from a nominal PN offset of the given sector. The mobile station transmits a measurement message that includes the measured PN offset and the measured signal strength. The spread spectrum communication system receives the measurement message and determines a location associated with the mobile station (e.g., based on location coordinates included in the measurement message). The spread spectrum communication system determines the nominal PN offset of the given sector based on the measured PN offset and the location associated with the mobile station. If the given sector is a valid handoff destination, the spread spectrum communication system transmits to the mobile station a handoff instruction that identifies the given sector by the measured PN offset.

摘要： In order to provide wireless service to wireless communication devices (WCDs) at different altitudes (e.g., on different levels of a high-rise structure), a radio access network (RAN) may include antennas aimed to direct coverage at different heights. The RAN may advertise the presence of wireless coverage areas that provide elevated coverage primarily to the WCDs above a threshold altitude. Similarly, the RAN may advertise the presence of wireless coverage areas that provide ground floor coverage primarily to WCDs below the threshold altitude. In this way, when a WCD is handed off to a new wireless coverage area, that wireless coverage area may be suited to provide coverage at the WCD's altitude.

摘要： A mobile station receives system time information from a source base transceiver station (BTS) in a spread spectrum communication system. The mobile station estimates a distance between the mobile station and the source BTS. The mobile station calculates a propagation delay based on the estimated distance. The mobile station develops a propagation-delay-adjusted time reference based on the system time information and the calculated propagation delay. The mobile station uses the propagation-delay-adjusted time reference to search for a target pseudonoise (PN) offset corresponding to a target BTS in the spread spectrum communication system. The mobile station may be closer to the target BTS than the source BTS.
