摘要:
Advertising in connection with handing off a cell from one cell to another may be facilitated by segregating communication descriptors into a common part that does not change in different types of cells and a unique part that changes in different types of cells. The unique parts may be advertised more frequently than the common parts.

Techniques to improve data communications for a wireless system are described. An apparatus may include an asymmetric data channel manager to perform asymmetric link adaptation for multiple wireless data channels based on a class of data flow for each data channel. Other embodiments are described and claimed.

A method of managing network traffic within a wireless network (100) comprises identifying a plurality of base stations (111, 121, 131) within the wireless network, categorizing each one of the plurality of base stations according to its type, setting a load balancing parameter (α) for each one of the plurality of base stations according to its type, and, for a handover event involving a handover from a first one of the plurality of base stations to a second one of the plurality of base stations, selecting the second one of the plurality of base stations according to a process that takes into account the load balancing parameters of both the first one of the plurality of base stations and the second one of the plurality of base stations.
摘要:
Techniques to permit scheduling of mixed radio access technologies. In some cases, a first radio access technology mode of a base station is scheduled during a first time region and a second radio access technology mode of a base station is scheduled during a sleep mode of the first radio access technology mode. In some cases, a first radio access technology mode of a base station is scheduled during a first time region and a second radio access technology mode of a base station is scheduled during an unused portion of the first time region. In some cases, a femto-base station is scheduled to snoop for local mobile stations during a sleep mode. Inactive regions of mobile stations are scheduled during a portion of sleep modes of the radio access technology modes.
摘要:
Overlay handover is generally presented. In this regard, a method is introduced including storing a broadband wireless network composite signal in a sample buffer, processing the sample buffer using subcarriers associated with a serving base station to determine a bandwidth grant from a first MAP, and reprocessing the sample buffer using subcarriers associated with a neighboring co-channel base station to determine a bandwidth grant from a second MAP. Other embodiments are also described and claimed.
摘要:
An embodiment of the present invention provides an apparatus, comprising a transceiver adapted for use in a hop by hop (HbH) relay network and configured to enable fast error correction and reduce ARQ overhead by coupling HARQ and ARQ feedback signaling in each hop of the HbH relay network.
摘要:
Methods and apparatuses for scheduling transmissions between a base station and multiple user stations in a broadband wireless access network may include a subscriber station generating a bandwidth request which includes one of a limited number of available and predefined preamble sequences and a data portion identifying the resources requested. The subscriber station randomly selects a contention slot in a wireless channel, allocated by the base station, for sending a bandwidth request. The receiving base station is able to detect the preamble sequence of bandwidth requests and differentiate between subscribers even when bandwidth requests of two or more subscribers may collide by virtue of selecting the same contention slot. In this manner, latency and overhead of bandwidth requests may be improved. Additional variants and embodiments are also disclosed.
摘要:
Network traffic may be estimated using samples of network activities to identify traffic parameters. A model of the network may be generated using the traffic parameters, and the model can be used to simulate the network using a modified set of parameters. Network traffic may be managed using the results of the simulation. Network traffic can also be managed by intercepting and modifying a control message on a peer-to-peer network.
摘要:
Various embodiments of the invention may use adaptive polling in a wireless network when one or more consecutive polls show that the polled station has no data to transmit. When triggered to perform adaptive polling, a base station may wait for increasingly long intervals between polls to a particular subscriber station, until some maximum interval has been reached. In some embodiments, the intervals may increase exponentially.

An embodiment of the present invention provides an apparatus, comprising a transceiver adapted to reduce ARQ overhead by coupling HARQ and ARQ feedback signaling and defining different HARQ burst regions that enable different regions to use different HARQ feedback configurations based on channel quality or QoS requirements.
