摘要:
A method and apparatus for requesting a ChannelMeasurementReport in a wireless communication system are described. A ChannelMeasurementReportRequest message comprising an 8 bit MessageID field set to “0x07”, a 12 bit PilotPN field wherein the PilotPN field is set to the PilotPN of the sector requesting the measurement report, a 2 bit CarrierID field wherein the CarrierID field is set to the carrier on which the measurements are requested, a 40 bit StartPHYFrame wherein the StartPHYFrame is set to the frame number of the PHYFrame where access terminals are required to being measurements, a 3 bit NumChannels field wherein the NumChannels field is set to the number of channel to be measured, an 8 bit MeasurementsPerMessage field wherein the MeasurementsPerMessage determines the number of measurements to be included in one report message, an 8 bit NumMeasurementsRequested field wherein the NumMeasurementsRequested determines the total number of measurements to be made by access terminal and a 4 bit Reserved field is generated and transmitted over a communication link.
摘要:
Transmission patterns for pilot symbols transmitted from a mobile station or base station are provided. The pattern allows for improved receipt of the pilot symbols transmitted for frequency selective channels and users. In addition, schemes for improving the ability to multiplex pilot symbols without interference and/or biasing from different mobile stations over the same frequencies and in the same time slots.
摘要:
Briefly, in accordance with one embodiment, a method of transmitting signals is provided. Signal waveforms are transmitted from at least two respective sectors. The at least two respective sectors are from at least two different sets of a superset of sectors. The transmitted signal waveforms include signal waveforms at least nearly mutually orthogonal at least along a particular signal dimension. An advantage of such an embodiment, for example, is reduced signal interference.
摘要:
Certain embodiments of the present disclosure relate to a method to determine appropriate values of cyclic delays applied at a transmitter with multiple antennas in order to provide accurate estimation of channel gains in a multiple-input single-output (MISO) system or multiple-input multiple-output (MIMO) system.
摘要:
Certain embodiments of the present disclosure provide a method for scanning for paging messages in a second radio access technology (RAT) network, such as a CDMA network, while connected to a first RAT network, such as a WiMAX network. For certain embodiments, an enhanced scanning request message may facilitate establishing a scanning cycle in the first RAT that aligns with a paging cycle of the second RAT.
摘要:
A selected rate is received for an apparatus based on a hypothesized signal-to-noise-and-interference ratio (SINR) for the apparatus, and characterized statistics of noise and interference observed at a receiver for the apparatus. Data are processed in accordance with the rate selected for the apparatus.
摘要:
Certain embodiments of the present disclosure allow for detection of a transmitted preamble sequence by processing a correlation of a received signal and a preamble hypothesis in a way that exploits the good correlation properties of the known set of preamble sequences. For certain embodiments, the highest peaks of the correlation output may be compared across all preamble hypotheses to decide which preamble sequence is transmitted.
摘要:
Techniques for sending and receiving signaling in a wireless communication system are described. Multiple (e.g., eight) vectors of modulation symbols may be defined and may be orthogonal to one another. Multiple subscriber stations may share transmission resources and may simultaneously send different vectors of modulation symbols in the same tile. Each subscriber station may be assigned multiple sets of at least one vector of modulation symbols usable by that subscriber station to convey signaling, e.g., one set of three vectors for acknowledgement (ACK) and another set of three vectors for negative acknowledgement (NAK). Each subscriber station may send one set of at least one vector in at least one tile to convey a signaling value. Different subscriber stations may simultaneously send different sets of at least one vector in the at least one tile to convey their signaling values.
