20090238090 | COMMON DATA CHANNEL RESOURCE USAGE REPORT - Systems and methodologies are described that facilitate indicating channel resource usage information for receiving additional channel resources in a wireless network. An access point can initially receive a set of channel resources from a network controller for providing wireless network access to one or more devices. The access point can grant and/or deny requests for one or more of the channel resources from a plurality of devices and can feedback information to the network controller regarding the granting/denying. The network controller can determine a load on the access point based at least in part on the feedback information and adjust channel resource allocation based on the load. Thus, where an access point has granted close to capacity of allocated resources to one or more devices, the network controller can provide additional resources to the access point based on received feedback information related to the granted resources. | 09-24-2009 |

20100185910 | METHODS AND SYSTEMS FOR SETTING CID MASK LENGTH OF A HARQ-MAP/SUB-MAP POINTER IE IN WIMAX SYSTEMS - Methods and apparatus for setting the connection identifier (CID) mask length of a Hybrid Automatic Repeat-Request (HARQ)-MAP or a SUB-MAP pointer information element (IE) in a compressed downlink map (DL-MAP) of an orthogonal frequency-division multiple access (OFDMA) frame are provided in an effort to reduce the number of false indications in the CID mask, while also striving, as a secondary concern, to reduce the CID mask length.

20100208700 | METHODS AND SYSTEMS FOR SELECTING A HANDOVER BASE STATION IN MOBILE WIMAX - Methods and apparatus for improving performance and robustness of a handover procedure. For example, by handing over to a target base station (BS) that is co-located with a serving BS (i.e., a BS located in the same physical node as the serving BS), mobile station (MS) context transfers, handover preparation and downlink (DL) data continuity between the serving BS and the target BS may be simplified because the serving BS and the target BS are in the same physical node.

20140029582 | METHOD AND APPARATUS FOR A POWER CONTROL MECHANISM - A user equipment (UE) may reduce the difference in transmit power between the uplink channel and enhanced high speed channel so that the base station may decode the uplink channel. The UE may determine the transmit power level for the uplink channel, such as dedicated physical channel, and the transmit power level for the enhanced high speed channel, such as shared information channel, and reduce the power difference when the power difference is greater than a threshold. The power difference may be reduced by increasing or decreasing the power of the enhanced high speed channel and/or increasing or decreasing the power of the uplink channel. | 01-30-2014 |
20140119211 | ALLOCATION OF VOICE IDLE TIME PERIOD FOR INTER-RAT MEASUREMENT - To create gaps in communication activity to perform inter radio access technology (IRAT) measurement, a user equipment may isolate silent periods during voice communications. During those silent periods, instead of transmitting special bursts with erasure packets indicating silent periods, the UE may allocate the time slots that would otherwise have sent the special bursts and indicate those slots as idle so they may be used for other purposes, such as IRAT measurement. | 05-01-2014 |
20140119344 | ADAPTIVE ALLOCATION OF IDLE SLOTS BASED ON ERROR RATE - To create additional communication gaps for a user equipment to perform inter-radio access technology (inter-RAT) measurement, the user equipment may discontinue communications during time slots of specific transmission time intervals (TTIs) based on a block error rate of a previous TTI.
