摘要： Systems and methodologies are described that facilitates managing assignment of available random access resources in order to minimize delay and random access load. A number of available random access resources can be defined by a network or a base station, wherein a user equipment can access the number of available random access resources via an information block. The user equipment can be randomly assigned or uniformly assigned to at least one of the number of available random access resources. Additionally, the network can adjust the defined number of available random access resources based upon reported delay, base station load, or historic load data for a base station.

摘要： Systems and methodologies are described that facilitate effectuating a random access procedure in a wireless communication environment. A random access preamble can be sent from an access terminal to a base station, and a random access response can be sent from the base station to the access terminal in response. The random access response can allocate resources to be utilized by the access terminal for a scheduled transmission (e.g., message 3, . . . ). Further, a plurality of Transmission Time Intervals (TTIs) can be bundled for the scheduled transmission. Moreover, a payload of the scheduled transmission can be transmitted to the base station from the access terminal within a common Transport Block (TB) using the bundled plurality of TTIs. According to an example, employment of TTI bundling can be controlled on a per network basis, per base station basis, or per access terminal basis.

摘要： Techniques for sending packets and maintaining synchronization during handover is described. A user equipment (UE) may be handed over from a source base station to a target base station. The source base station may forward packets for the UE to the target base station, which may receive the packets out of order. In one design, the target base station may determine whether each packet can be sent in order to the UE, send the packet if it can be sent in order, and discard the packet otherwise. In another design, the target base station may re-order packets received within a re-ordering window and may send the re-ordered packets to the UE. In yet another design, the target base station may process each packet received out of order as if the packet is in order, e.g., by incrementing a hyper-frame number (HFN) or re-assigning the packet with a later sequence number.

摘要： Systems and methods for managing packetized data handoff between base stations in a mobile communication system are described. In one aspect, a timer is utilized to decide when to perform path switch from serving traffic forwarded by the source station to traffic received by the serving gateway, and to preserve, to a large degree, the packet order from a gateway device to a terminal, during the handoff between base stations. When handoff is indicated, the timer is started and only packets that are received by the source base station is forwarded to the terminal, while the timer runs. When the timer expires, the target station switches to transmit fresh packets received from the serving gateway. The timer can be adjusted “on the fly” and has been demonstrated to maximize TCP throughput as compared to a fixed switch timer.

摘要： Beacons may be grouped to facilitate neighbor discovery in a wireless network. For example, neighboring access devices such as IEEE 802.11 access points may cooperate to transmit beacons in a group. In this way, a wireless device seeking to discover the neighboring access devices may scan for the beacons for a shorter period of time. An indication may be provided to enable a wireless device to more efficiently scan the beacons. For example, the indication may indicate the channel the wireless device should scan to receive the next beacon that is to be transmitted. In addition, the indication may include information relating to the transmission time of the next beacon.

摘要： Broadcast or multicast traffic is classified into different types of traffic such that different types of traffic are transmitted over different sub-networks. In addition, different transmission schedules may be associated with each of the different sub-networks. A device may thus be configured to receive only a selected portion of the different types of traffic by only waking from a power save mode at the intervals at which the corresponding sub-network sends the traffic. The standby time of the wireless station may thus be improved because the wireless station may awaken less frequently and for shorter periods of time. Different sub-networks carrying different types of broadcast and multicast traffic may be implemented in an 802.11-based system. For example, a single access point may define multiple basic service set identifiers for a single wireless channel.

摘要： Techniques for avoiding collision of traffic in a wireless network are described. A station detects for synchronization of its traffic with traffic of other stations. The station may detect for synchronization based on, e.g., percentage of first transmission failures, counters indicative of statistics of transmitted frames, and/or other information. The station may confirm synchronization of its traffic, e.g., by monitoring for traffic from another station during a service period for the station. The station adjusts transmission of its traffic when synchronization is detected to avoid collision with the traffic of the other stations. The station may delay transmission of its traffic by a predetermined amount of time, by a pseudo-random amount, or until after the other stations finish their transmissions.
