摘要： A method and a system for scheduling requests generated for a plurality of mobile devices in a communication network (100) has been disclosed. The requests are generated for a transmission opportunity. The method includes computing a sort metric (302) for each request, based on an information update. A lead-time is then computed (304) with respect to a drop-dead time for each request, based on the sort metric for a time slice. The drop-dead time for a given time slice is the time before which scheduling has to be done so that data can be transmitted during the given time slice. Each request may be considered (306) for allocation in the time slice before the beginning of a next time slice, based on the lead-time.

摘要： In a wireless network, a device monitors (310) at least one parameter that indicates collision status in the network; compares (320) the at least one parameter to a predefined control frame threshold that is based on a criterion other than packet-size; and activates (330) a control frame feature in the device for sending a control frame prior to data transmission, when the at least one parameter exceeds the control frame threshold. In an 802.11 network, the control frames are RTS (request-to-send) and CTS (clear-to-send) frames. The parameters being monitored can include: a number of acknowledgement and RTS frames detected from a hidden terminal, when the device is in a backoff state; a number of retransmission attempts by the device; and a collision rate determined and transmitted by another device in the wireless network to which the device intends to send data.

摘要： The present invention provides a method for managing transmissions in a wireless communication network (100). The method at a first node (102) of a plurality of nodes of the wireless communication network includes transmitting (304) a data frame to a second node (104) using a first transmit power level. The method further includes determining (306) whether an acknowledgement for the transmitted data frame is received from the second node. Further, the method includes determining (308) a cause of unsuccessful transmission when the acknowledgement is not received from the second node. Moreover, the method includes re-transmitting (310) the data frame to the second node using a second transmit power level when the cause of unsuccessful transmission is determined as a collision. Furthermore, the method includes setting (312) a transmit power level of the first node to a third transmit power level.

摘要： A base station [500] has a transmission element [505] to wirelessly transmit at least one data frame. The at least one data frame has a predetermined uplink allocation and a predetermined downlink allocation. A detection element [510] detects a congestion condition. When the congestion condition is detected, the transmission element [505] transmits a request to at least one neighboring base station for an expansion of the predetermined uplink allocation or the predetermined downlink allocation. A reception element [515] receives a signal from the at least one neighboring base station. A processing element [520] expand the one of the predetermined uplink allocation or the predetermined downlink allocation by a specified amount in response to the signal indicating the specified amount for a mutually agreed time, or number of symbols or frames.

摘要： An apparatus and method for determining (410) a quality of channel factor for a base transceiver station (530) of an active set and determining (420) whether the base transceiver station (530) should be assigned to a prefill set at least in part according to a predetermined function of the factor. The predetermined function may include assigning (425) a base transceiver station (530) to the prefill set when the quality of channel factor reaches a predetermined threshold. The quality of channel factor may be determined in various ways including executing (416) an anticipative signal strength algorithm or by monitoring (412) the quality of channel between the mobile station (110) and the base transceiver station (530). Additionally, the primary base transceiver station (120) may be notified (430) of the prefill set such that synchronization signals may be sent (440) to the base transceiver stations of the prefill set.

摘要： An apparatus and method for monitoring (310) at least one factor relating to a wireless communication system (100) is provided such that a synchronization signal is sent (320) to at least one base transceiver station (130) neighboring a primary base transceiver station (120) at least in part according to a predetermined function of the monitored factor(s). The monitored factor may be any of several factors that weigh on the operation of the wireless communication system. The synchronization signal itself may vary in how it signals to the neighboring base transceiver station(s) (130) to synchronize with the data to be sent to a given mobile station (110) from its primary base transceiver station (120), and the number of synchronization signals sent over a given time may vary according to the predetermined function of the monitored factor(s).
