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.

摘要： A communication system comprises a wireless access node having a plurality of ports and a control system. The wireless access node is configured to exchange wireless communications over the ports with wireless communication devices that are individually identified by device identifiers. The control system is configured to individually allocate the wireless communication devices into categories based on the device identifiers and determine one of the categories having a majority of the wireless communication devices. The control system is configured to configure the ports of the wireless access node to utilize a MIMO 2T2R mode for exchanging the wireless communications if the one category having the majority of the wireless communication devices comprises a first data rate capability, and to configure the ports of the wireless access node to utilize a MIMO 4T4R mode for exchanging the wireless communications if the one category having the majority of the wireless communication devices comprises a second data rate capability.

摘要： An access network may be maintaining data indicating which of its coverage areas have a short occupancy time. The access network may then conduct a first paging of an access terminal in each coverage area in a first set of coverage areas, the first set including a subset of coverage areas having a short occupancy time. Thereafter, the access network may determine that it has not received a response to the first paging from the access terminal during a first timeout period, which is preferably shorter than a predefined paging timeout period. In response, the access network may conduct a second paging of the access terminal in only each coverage area in the subset of coverage areas (i.e., the coverage area(s) in the first set of coverage areas that have the short occupancy time).

摘要： Disclosed is a method and system to help reduce the extent of roaming or use of lower priority coverage areas in a wireless communication system, by selectively managing the level of noise in a preferred coverage area. A network entity will detect that a particular coverage area has a high rate or roaming or that another coverage area (e.g., a collocated or adjacent coverage area) has a high rate of use, and the network entity will responsively reduce a noise threshold in the particular coverage area so as to then tolerate less noise in the coverage area before taking affirmative action to reduce the level of noise, and thus optimally to reduce the extent of roaming or use of less preferred coverage.

摘要： A multi-mode mobile station is able to communicate with a first system using a first air interface protocol (e.g., EVDO) and with a second system using a second air interface protocol (e.g., 1×RTT CDMA). When the first system schedules a page message for transmission to the multi-mode mobile station, the first system may query the second system to determine whether the second air interface protocol is being used for a current call involving the multi-mode mobile station or is being used to attempt establishment of a requested call to the multi-mode mobile station. In the case of a current call, the first system may wait until the call is released before transmitting the page message. In the case of an attempt to establish a requested call, the first system may wait to determine whether the attempt is successful before transmitting the page message.
