摘要:
An embodiment of the present invention provides a method of supporting multiple protocols in a wireless network operating according to an Institute for Electronic and Electrical Engineers IEEE) 802.16 standard, comprising adding a new convergence sub layer (CS) type in which an extra field is added to an 802.16 service data unit (SDU) to indicate which higher layer protocol is carried in a 802.16 SDU payload.
摘要:
Complex antennas weights for use in beamforming in a multiple-antenna system are determined based upon clear channel assessment (CCA) information in a wireless networking environment.
摘要:
In a multicarrier transmitter that transmits two or more spatial data streams, a bit distributor assigns encoded bits to the spatial data streams based on bit-loading capabilities of the streams and in a manner to intermix the bits among the spatial streams.
摘要:
An apparatus and associated methods for performing space-frequency interleaving in a multicarrier wireless communication system is generally described.
摘要:
Subcarrier phase rotation is implemented in an OFDM transmitting apparatus to overcome problems such as, for example, non-frequency selective multipath fading. In at least one embodiment, subcarrier phase rotation is practiced in an OFDM system implementing multiple input multiple output (MIMO) techniques.
摘要:
Methods, protocols and systems for communicating in a multi-hop wireless mesh network may include explicitly providing information relating to backhaul wireless link qualities in multi-hop wireless mesh network to next generation subscriber stations in a first mode. In a second mode, embodiments are configured to implicitly provide indicia of multi-hop wireless link qualities to legacy subscriber stations by adjusting a transmit power of frames sent to the legacy subscriber stations. Other embodiments and variations are described in the detailed description.
摘要:
Partial channel information is used to weight signals being transmitted by cooperating nodes within a cooperative diversity arrangement. In at least one embodiment, the phase of the complex conjugate of a channel coefficient between a cooperating node and a remote device is used to weight a transmit signal.
摘要:
Methods and devices for wireless networks for extending the communications range of an originating device without increasing its transmit power or bandwidth. An originating device may include signaling in a physical (PHY) layer packet such that peer network devices may know to retransmit the received packet substantially in synchronization with one another. The subsequent and substantially simultaneous transmission of the original signal by peer network devices may effectively increase the range of the originating device so a transmission may reach its destination. Various embodiments and implementations are also disclosed.
