Abstract: A method for selecting a wireless coverage sector to serve a mobile station, such as in response to a handoff request that designates a sector-identifier that represents two or more possible sectors. A serving radio access network (RAN) may identify potential sectors in the region and may then select the sector whose azimuth is closest to the geographic bearing of the mobile station from the sector's base station. Further, in the event of a tie between two or more sectors or in other circumstances, the RAN may also take into consideration how close the mobile station is to various base stations, such as selecting the sector to whose base station the mobile station is closest. In a system that uses neighbor lists to govern handoff, the invention can help to facilitate handoff in a scenario where a mobile station requests handoff to a sector not listed in the mobile station's neighbor list.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
