摘要： A system and method for reducing an initial network entry and/or handover (INE/HO) Link Budget (LB) Bottleneck in a communications network, for example, a Worldwide Interoperability for Microwave Access (WiMAX) network described in the IEEE 802.16 specification, is arranged such that a Base Station (BS) may allocate bandwidth with repetition across at least two frames on Initial Network Entry/Handover (INE/HO) by a Mobile Station. By doing so, the BS may achieve increased system gain on INE, while reducing the number of subchannels conventionally associated with repetition, thereby reducing the system noise floor during INE/HO.

摘要： A base station may decide to initiate a handover of a communication with a mobile station from a first wireless link to a new wireless link and identify one or more wireless links for the handover. For each identified wireless link, the base station may then determine a channel-quality metric, a wireless-link loading metric, and perhaps a coverage-area loading metric. In turn, the base station may then select the new wireless link based on the channel-quality metric and one or both of the wireless-link loading metric and the coverage-area loading metric. For example, the base station may apply a linear function that includes as variables the channel-quality metric and the wireless-link loading metric, and the base station may select the identified wireless link that best satisfies this function. The base station may then facilitate the handover of the communication from the first wireless link to the selected new wireless link.

摘要： A system and method of a hybrid scheme of DL link adaptation in a network having mobile stations (MSs) in communication with a base station (BS). The system may include a mode decision module associated with the base station. The mode decision module may include one or more processors configured to select a first mode configuration for use during transmission of a first communication from the base station. The BS may receive first feedback information associated with the first communication, where the first feedback information includes a first mode recommendation and first channel information. Based on the first feedback information, the BS may generate a BS-derived mode configuration based on the first channel information and compare the first mode recommendation and the BS-derived mode configuration. Based on the comparison, the BS may determine a second mode configuration to use to configure a second communication.

摘要： In various embodiments, a system and method for providing uplink (UL) power control for a wireless mobile station (MS) includes, after transmission of an unanswered bandwidth request by the MS, incrementally boosting an UL transmit power of one or more subsequent bandwidth requests by the MS to a boosted UL power level at which UL bandwidth is allocated to the MS by the BS; selectively reporting the boosted UL power level to the BS immediately after the UL transmit power has been boosted; and selectively controlling the boosted UL power level by the BS responsive to the boosted UL power level reported to the BS. A MS is configured to carry out the UL power control method and a BS is configured to generate MS UL power control commands based, at least in part, upon the UL power level reported to the BS.

摘要： A plurality of ranging processes are performed to monitor a status of a wireless link associated with a device identifier. A ranging request that includes the device identifier and a message skip indicator is received. It is determined that the device identifier is already associated with the wireless link. A duration since a previously completed ranging process is determined. Based on the duration, and the message skip indicator, it is determined whether to respond to the ranging request.

摘要： A method and system for allocating control channel resources. After initially allocating control channel elements to user equipment (UE), a processing unit may engage in a modification process in an effort to optimize the allocation, which may involve changing a number of control channel elements, taking into account transmission power headroom and predicted error rate.
