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.

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： Methods and devices for a radio access network (RAN) to select a wireless communication device (WCD) for handoff to a given sector are presented. In particular, the RAN may receive resource requests from a first WCD and a second WCD, both WCDs contending for a resource of the given sector. Based on the each WCD's active sets of sectors, the RAN may grant the resource to one of these WCDs. Preferably, the RAN grants the resource to the WCD that is more likely to benefit from use of the resource.

摘要： A mobile station transmits a message by transmitting an access probe that includes the message preceded by a preamble. The mobile station selects the length of the preamble from among a first preamble length and a second preamble length. The second preamble length is greater than the first preamble length. The mobile station makes the selection based, at least in part, on the distance between the mobile station and the mobile station's primary base transceiver station (BTS). If the distance is greater than a threshold distance, the mobile station selects the second preamble length. If the distance is less than the threshold distance, the mobile station selects the first preamble length, provided that an idle handoff to a neighboring BTS that is more than the threshold distance away is unlikely.

摘要： A method and system is disclosed for selectively scheduling control channel messages ahead of traffic channel data. When a RAN in a wireless communication system operating at least according to IS-856 determines that a delay condition exists in the transmission of a particular control packet to access terminals, the RAN will determine if there is a particular traffic packet in active transmission that is classified according to best effort service (or similarly-characterized service class), and further if at least a threshold number of a nominal number of time-slot segments of the particular traffic packet remain untransmitted. If such a traffic packet is identified, the RAN will cancel transmission of the particular traffic packet and replace it with immediate transmission of the particular control packet.
摘要翻译：公开了用于在业务信道数据之前有选择地调度控制信道消息的方法和系统。当至少根据IS-856操作的无线通信系统中的RAN确定在向接入终端发送特定控制分组时存在延迟条件时，RAN将确定是否存在主动传输中的特定业务分组根据尽力服务（或类似特征的业务类别）进行分类，以及进一步地，如果特定业务分组的至少一个阈值数量的时隙段的标称数目保持未被发送。如果识别出这样的业务分组，则RAN将取消特定业务分组的传输，并将其替换为特定控制分组的即时传输。
