Therefore, when the requesting end and the destination end perform data transmission on the traffic flow, the FID alone can sufficiently serve as the identifier, so as to save the need of carrying the destination end identifier in each exchanged data packet, thereby simplifying the operation. | 03-27-2014 |
20140086169 | METHOD AND DEVICE FOR ACCESSING WIRELESS NETWORK - The present invention provides a method for accessing a wireless network, so as to implement acquisition of system synchronization during the process of accessing the wireless network in the situation that a physical frame structure can be configured dynamically. The method for acquiring system synchronization comprises: searching a physical frame on a current sub-channel; resolving a system information channel (SICH) and a control channel (CCH) in the found physical frame, wherein the SICH indicates a structure of the physical frame, and the CCH indicates allocation of system resources; and acquiring a system parameter from the physical frame by using the resolving result. A device for implementing the above method is further provided. | 03-27-2014 |
20140086222 | METHOD AND DEVICE FOR USE IN FRAME ACKNOWLEDGEMENT - Provided in the present invention are a method and device for use in frame acknowledgement. The method comprises: bearing an immediate acknowledgement instruction into a data frame, the immediate acknowledgement instruction is for use in instructing an immediate return frame acknowledgement response; and transmitting the data frame having the immediate acknowledgement instruction attached thereto. | 03-27-2014 |
20140112264 | Resource Request Method, Station, and Central Access Point - The present invention provides a resource request method, a station, and a central access point. The method comprises: bearing a transmission resource request in a data frame; and sending the data frame carrying the transmission resource request. The method provides a solution for acquiring resources required by uplink transmission data. | 04-24-2014 |
20140313957 | Method and Device for Power Saving - The present invention discloses a method and device for power saving, receiving the hibernation instruction sent by the network side, one or multiple hardware units inside a station (STA) are turned off to allow the STA to enter a hibernation mode; When STA receives a service instruction from the network side or when the STA has data to be transmitted to a central access point (CAP) of the network side, all the hardware units turned off are turned on to allow the STA to terminate the hibernation mode. Application of the present invention allows within a certain period for a STA remain at a minimal power state, thus conserving power and air interface resources. | 10-23-2014 |
20150085732 | Method and Device for Open Loop Uplink Access Power Control - A method for open loop uplink access power control comprises: estimating the uplink transmission path loss according to received signal power of a station (STA) and the transmit power of a central access point (CAP); determining the transmission bandwidth allocated by the CAP for uplink transmission and deviation adjustment of the CAP; determining a modulation-coding mode and determining requirements of the carrier-to-noise ratio corresponding to the modulation-coding mode; and calculating a target value for adjusting the transmit power of the STA. Also disclosed is a device for open loop uplink access power control. | 03-26-2015 |
