摘要： An access network may identify paging areas based on a reference location (e.g., a mobile station's last known location), where each paging area includes at least one coverage area. The access network may then determine paging-channel occupancies for coverage areas in at least identified paging area. In turn, the access network may adjust a given identified paging area based on the determined paging-channel occupancies, resulting in an adjusted paging area. For example, the access network may add coverage areas to the given identified paging area and/or remove coverage areas from the given identified paging area based on the paging-channel occupancies for those coverage areas. Thereafter, the access network may page a mobile station associated with the reference location in the adjusted paging area.

摘要： Methods and systems for adaptive hybrid automatic repeat request (H-ARQ) protocols are disclosed. The protocols preferably adapt to changing network conditions between a client node and an access node by omitting the transmission of certain messages when network conditions are determined to be favorable. In doing so, packets are processed faster, thus reducing communication latency as well as the memory requirements of the protocols. One scenario in which the protocols may operate is where the client node is a wireless communication device coupled to the access node via a wireless network. In such a scenario, the access node may, from time to time, measure a quality of the wireless air interface between the client node and the access node, and determine whether to transmit an acknowledgement message based on the outcome of the measurement as compared to a threshold value.

摘要： 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.

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： 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： An access terminal establishes a session with a first radio access network (RAN). As a result, the access terminal receives a Unicast Access Terminal Identifier (UATI) assigned by the first RAN and establishes configuration settings for radio communications between the access terminal and the first RAN. The access terminal moves from the first RAN to a second RAN. Before the access terminal has a session established with the second RAN, the access terminal receives a request from a user to originate a call. In response, the access terminal sends the second RAN a connection request that includes the UATI assigned by the first RAN. The second RAN evaluates the UATI included in the connection request and determines that it was previously assigned to the access terminal by another RAN. Based on this determination, the second RAN grants the connection request by assigning a traffic channel to the access terminal.

摘要： During a first time interval, an access point transmits orthogonal frequency division multiplexing (OFDM) signals using a first cyclic prefix length. The access point selects a second cyclic prefix length based, at least in part, on the load of the access point. The access point transmits OFDM signals using the second cyclic prefix length during a second time interval. The load of the access point may be determined based on the amount of downlink data being buffered in the access point for transmission to one or more user devices.
