Abstract: 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.

A next step (402) includes increasing a reliability of the first uplink grant in response the higher than normal likelihood. Other next steps can include detecting (404) that the first Buffer Status Report transmission Hybrid Automatic Repeat Request process failed and triggering (406) a second Buffer Status Report transmission in the user equipment in a next uplink grant.

Abstract: A scheduler associated with a base station of a wireless communication network dynamically compensates for uplink bandwidth that has been re-assigned (stolen) by a mobile station (MS) to transmit a control message. The scheduler allocates a preset amount of bandwidth to the MS for data transmission. The scheduler detects bandwidth stealing activity and evaluates when bandwidth stealing is justified on he part of the MS. The scheduler provides additional bandwidth to appropriately compensate for the stolen bandwidth when bandwidth stealing is justified, in order to maintain the quality of service of the data traffic connection.

After the first buffer status report is sent, the amount of data in the buffer can change (216) so that the user equipment sends (218) a second buffer status report to indicate the change in the amount of data in the buffer that is to be sent.

Abstract: A system and method for reducing access channel delay in a wireless communication system includes a step 601 of sending an initial access request response that includes identifiers of any initial access requests, including an indicator that indicates whether any more responses with identifiers are going to be sent within a predefined time period. A next step 602 includes receiving the response. A next step 604 includes recognizing that a particular identifier from the initial access request is not in the response. A next step 606 includes determining from the indicator that there will be no more responses with identifiers sent within the predefined time period. A next step 608 includes transmitting another initial access request before the end of the predefined time period.

Abstract: A method and an apparatus that includes establishing a link (106) between a first node (102) and a second node (104) in a wireless communication network (100). The method continues by setting a discontinuous receive (DRX) transmission mode cycle for the link wherein the DRX cycle includes an on duration (202) followed by an off cycle (204). The duration of the on duration on a downlink is adjusted (610) based on a function of the availability of a channel quality indicator (CQI) channel used on the link.

Abstract: Logic circuitry (409) constantly monitors a transmitter (410) to determine if the transmitter (410) is idle. Logic circuitry (409) suppresses all NAKs until data and other channel information is not being transmitted by the transmitter (410) and RF resources are not scarce. Additionally, logic circuitry (409) suppresses all NAKs until a predetermined number of NAKs has been buffered by the logic circuitry (409). More particularly, logic circuitry (409) determines when a number of NAKs will sufficiently fill an over-the-air frame. Once the predetermined number of NAKs has been collected, the logic circuitry (409) will generate the appropriate NAKs.

Abstract: A method of allocating resources and signatures of a random access resource (RACH) (200) that includes dedicated (202) and non-dedicated (204) resources or sub-resources is disclosed. The network device determines if the dedicated resource is available for allocation. If the dedicated resource is available, the network device allocates the dedicated resource. If the dedicated resource is blocked, the network device allocates one of the non-dedicated resources. A message can be sent that indicates that allocated non-dedicated resource is being allocated as a dedicated resource.

Abstract: Multiple multicast data stream delivery in a communication network includes a first step (700) of providing a proxy agent for a mobile node. A next step (702) includes determining a multicast group the mobile node intends to join. A next step (704) includes receiving feedback about radio link characteristics of the mobile node by the proxy agent. A next step (706) includes using the radio link characteristics by the proxy agent on behalf of the mobile node to join or remove the mobile node from the group.

Abstract: A base station has a transmission element 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 detects a congestion condition. When the congestion condition is detected, the transmission element 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 receives a signal from the at least one neighboring base station. A processing element 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.

Abstract: 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).

Abstract: In a wireless network, a device monitors at least one parameter that indicates collision status in the network; compares the at least one parameter to a predefined control frame threshold that is based on a criterion other than packet-size; and activates 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.

Abstract: A communication resource that includes a communication channel is allocated in response to a received communication resource access request, wherein the access request is received while a message received via the communication channel is being demodulated. In response to receiving the request, a grant of access to the communication channel is generated and transmitted, which grant authorizes the source of the access request to use the communication channel.
