摘要： A method and system of determining whether a mobile station is located inside (or moving into) a repeater's coverage area and using the determination in a handover procedure. An access network may receive from a mobile station communicating on a first wireless link an indication of channel quality for the first wireless link and a second wireless link that serve the same coverage area. The access network may then use the channel quality indicators to determine whether the mobile station is located inside (or moving into) a repeater's coverage area, such as by comparing the channel quality indicators. If the access network determines that the mobile station is located inside (or moving into) the repeater's coverage area, it may also initiate a handover of the communication with the mobile station to the repeated wireless link (e.g., which may include suspending application of a load threshold to the repeated wireless link).

摘要： A method for varying pilot sub-carrier density in OFDMA communications is described. The method comprises calculating channel quality from sub-carriers; determining whether the channel quality is outside a threshold range; selecting a different pilot sub-carrier density for a sub-zone based on the value of the channel quality when the channel quality is outside the threshold range; and setting the sub-zone to the different pilot sub-carrier density. A system for using sub-zones with different pilot sub-carrier densities in OFDMA communications is also described.

摘要： In one or more embodiments, a system and method of managing network channel quality in a wireless communications network includes reporting a channel quality measurement from the particular user to a base station (BS) over an available CQICH, and determining a MCS based, at least in part, upon the channel quality measurement. If a threshold network CQICH capacity is reached during a subsequent data frame such that a CQICH is no longer available, MAC level messages are generated between the BS and the particular user to trigger reporting of signal quality information to the BS by the particular user. After the next CQICH cycle commences and if a CQICH is still unavailable, the signal quality information is continued to be provided via MAC level messages. Otherwise, a CQICH is reallocated for a particular user and channel quality measurement reporting is transitioned back to the CQICH.

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： Systems and methods of balancing traffic load in a wireless communication network include calculating a load metric for each of a plurality of users, wherein each of the plurality of users, in operation, are in communication with a first base station using an overloaded carrier associated with the first base station. Such load metric for each user may include a plurality of metric factors related at least to an associated communication link. Based on the calculated load metric, a transfer-deserving user from the plurality of users may be determined. The transfer-deserving user may be associated with a highest value of an associated calculated load metric. For load balancing at the first base station, the associated communication link of the transfer-deserving user may be transferred from the overloaded carrier to a target carrier, wherein the target carrier may be associated with either the first base station or a second base station.

摘要： In various embodiments, a method, computer-readable storage medium, and apparatus for scheduling prioritized best effort (BE) service flows through a wireless network base station includes a controller coupled to a memory. If any one of a plurality of BE service flows are congested, a minimum reserved traffic rate (MRTR) algorithm is used by the controller to ensure that at least a highest priority BE service flow is maintained at least at an associated MRTR. If none of the plurality of BE service flows are congested, a maximum sustained traffic rate (MSTR) algorithm is used by the controller to enable the highest priority BE service flow to be set to at least at an associated MSTR before lower priority service flows are increased. If none of the plurality of BE service flows are congested and each service flow is at their associated MSTR, the controller is configured to distribute any excess bandwidth to each service flow in accordance with an initial set of priority BE traffic flow ratios.
