摘要： Disclosed herein are methods and systems for managing usage of traffic-channel resources in an access network, which are preferably resources that are reserved during a traffic channel assignment (TCA) process. An exemplary method comprises (i) a base station determining a usage level of at least one traffic-channel resource in a coverage area of the access network; (ii) based at least in part on the determined usage level, updating one or more TCA parameters affecting expected usage of the traffic-channel resource resulting from the TCA process; and (iii) performing the TCA process according to the updated TCA parameters. Preferably the usage level is determined for Medium Access Control Identifiers (MAC_IDs). Further, the access-channel occupancy (ACO) may be determined and the base station may further base the updating of TCA parameters on the ACO. In an exemplary embodiment, the updated TCA parameters include the TCA count and/or the TCC wait timer.

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： 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： During connection establishment, an access network and/or an access terminal may decide whether to transmit bearer-traffic data rather than null-traffic data based on a channel quality of a wireless link. For example, if the access network has forward bearer-traffic data ready for transmission to the access terminal during connection establishment, the access network may decide to transmit that forward bearer-traffic data rather than forward null-traffic data in response to determining that a forward-channel quality of the wireless link is sufficient to carry such data. As another example, if the access terminal has reverse bearer-traffic data ready for transmission to the access network during connection establishment, the access terminal may decide to transmit that reverse bearer-traffic data rather than reverse null-traffic data in response to determining that a reverse-channel quality of the wireless link is sufficient to carry such data.

摘要： Methods and computer-readable media are provided to determine which sector the mobile device will bias during soft handoff. Signals are received from multiple sectors, and for a first quantity of time slots of a frame, the signals are inspected to determine whether a quality threshold is met. Based on whether the quality threshold is met, each sector is assigned a power control command indicating that either a decrease or increase of output power is recommended when a subsequent signal is sent to the mobile device. For a second quantity of time slots, the overall power control command sent to the sectors corresponds to the power control command assigned to the sector that has communicated the highest quality signals for the first quantity of time slots of the frame.

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： 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.
