摘要： A mobile station involved in a call receives a forward link signal from a radio access network (RAN) and transmits a reverse link signal to the RAN. If the mobile station detects a reception failure of the forward link signal, such as the receipt of an errored frame, the mobile station transmits a wait time to the RAN. The wait time specifies how long the reception failure can continue before the mobile station will discontinue transmitting the reverse link signal. In response, the RAN may increase the transmit power level at which the RAN transmits the forward link signal, such that a maximum transmit power level is reached during the wait time. The wait time could be based on a user preference and/or user behavior with respect to abandoning calls.

摘要： A spread spectrum communication system includes a base station that is able to transmit wireless signals that are spread by any of a plurality of orthogonal spreading codes and receive wireless signals that mobile stations transmit in an access channel. One of the orthogonal spreading codes is reserved as an indicator code that the base station uses to indicate when the access channel is occupied by a transmission from a mobile station. When the base station detects a transmission in the access channel, the base station estimates a completion time when the transmission will be completed and transmits an indicator signal spread with the indicator code until the completion time is reached. Before a mobile station transmits a message in the access channel, the mobile station determines whether the access channel is occupied by determining whether the base station is transmitting the indicator signal.

摘要： While a first entity and a second entity are engaging in a communication session on multiple wireless links, the first entity may adjust the power level at which to send power control commands (PCCs) directed to the second entity based on a respective channel quality at which each wireless link is carrying the communication session. For example, the first entity may identify which wireless link is carrying the communication session at a best channel quality and then cause an increase of a transmission power at which to send PCCs directed to the second entity on the identified wireless link. As another example, the first entity may determine that a respective channel quality of each wireless link satisfies a given condition and then cause an adjustment of a respective transmission power at which to send PCCs directed to the second entity on each wireless link.

摘要： Methods and systems use traffic channels to extend wireless coverage areas. In an embodiment, an access node transmits a standard pilot signal over a pilot channel. The access node initially operates in a standard transmission mode, wherein the access node transmits a standard traffic signal over a traffic channel at a first power level. The access node makes a determination to operate in an alternative transmission mode involving the access node generating and transmitting a modified traffic signal comprising (i) a standard traffic signal and (ii) a modified pilot signal. The access node transmits the modified traffic signal at a second power level that is greater than the first power level.

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.
