摘要:
The present invention discloses a method for feeding back channel information, which includes: configuring a same codebook space at a data transmitting end and a data receiving end (101); the data receiving end selecting, from the codebook space, a codeword matched with a channel, and transmitting a sequence number corresponding to the codeword to the data transmitting end (102); and the data transmitting end extracting, according to the sequence number, a corresponding codeword from a locally-configured codebook space to obtain channel state information (103). The present invention also discloses a system for feeding back channel information, which includes a data transmitting end and a data receiving end. The method and system for feeding back channel information solve the problem that there is no channel information feedback method for dual-polarized channels.

The disclosure provides a method for channel information feedback and a terminal, applied in an 8 antennae system, comprising: a terminal acquires the channel information which comprises PMI1 information and RI information; the terminal jointly encodes the PMI1 information and RI information into a 5 bit Report Type; the terminal feeds back the Report Type on a physical uplink control channel. The disclosure solves the poor transmission performance of the system caused by high overhead of channel information feedback in the related arts, thus improving the performance of the terminal to feed back information and improving the transmission performance of the system.
摘要:
An exemplary method of controlling communications includes determining a total congestion window size for a router device. An allocation of at least a portion of the determined total congestion window size to allocated at least one mobile station that communicates with the router device over a wireless link is determined based on the determined total congestion window size. The determined allocation is then reported to a source of a communication intended for the at least one mobile station.

The method also includes determining a plurality of priority metrics associated with the plurality of subcarriers and the at least one mobile unit, and assigning at least one of the plurality of subcarriers to the at least one mobile unit based on the plurality of priority metrics and the interference mitigation pattern.
摘要:
A method and system for acquiring channel information are disclosed in the present document, wherein the method includes: a base station and a User Equipment (UE) jointly saving a first codebook and at least a second codebook, and the first codebook being used for channel information quantization in various scenarios; the UE performing feedback of at least 2 Precoding Matrix Indicators (PMIs) to the base station, wherein, one PMI corresponds to one code word in the first codebook, all the other PMIs respectively correspond to different code words in a second codebook used currently, and all the code words corresponding to the fed back PMIs are used for representing channel information of one or multiple or all subbands; and after receiving the PMIs fed back from the UE, the base station finding corresponding code words from the first codebook and the second codebook used currently, and acquiring the channel information.
摘要:
A method and an apparatus for wireless communication between a receiver and a transmitter in a cellular system are provided. The method comprises associating a channel of known structure at the transmitter with the transmission of a first control channel to indicate a variable structure of the first control channel to the receiver.
摘要:
A method is provided for communicating data belonging to at least one application flow (AF). In one aspect, the method involves mapping the data to payload bits of two or more encoder packets (EPs) such that each said EP carries a payload dedicated to only one AF, and transmitting the EPs concurrently. In a second aspect, the above said mapping is inverted at a receiver.
摘要:
The present invention provides a method and an apparatus for adapting a data rate that a mobile station indicates to a base station for transmission on a forward link in a cellular system. The method comprises measuring a first value indicative of strength of at least one of a primary and a secondary pilot. The method further comprises compensating the first value indicative of strength of the pilot based on an offset to select a second value indicative of the data rate for the base station. The base station may determine an offset value for compensation and send an indication to the mobile station during the setup of the mobile station. When the mobile station connects to the base station, a measurement of a channel condition (i.e., pilot) may determine a revised data rate for transmission of a next data packet on the forward link.
