摘要:
The disclosure relates to a device (200) for updating an initial backoff parameter (ECW min ), the device comprising: a monitoring stage (201), configured to monitor, during a monitoring interval, a plurality of data transmissions of a plurality of WLAN devices; an identification stage (202), configured to identify a number of successful data transmissions from the plurality of data transmissions; a derivation stage (203), configured to derive a weighting function based on successful data transmissions; a weighting stage (204), configured to weight the initial backoff parameter (ECW min ) of the monitoring interval with the weighting function to provide a weighted backoff parameter (ECW AVR or Average Re-Tx); and an updating stage (205), configured to update the initial backoff parameter (ECW min ) for a next monitoring interval based on the weighted backoff parameter (ECW AVR ).
摘要:
A client type communication device for communicating with an access point type communication device is provided. The client type communication device comprises a communication unit adapted to use at least one of first communication resources for performing a random access communication if the client type communication device is in an associated mode regarding the access point type communication device, and to use at least one of second communication resources different from the first communication resources for performing a random access communication to the access point type communication device if the client type communication device is in a non-associated mode regarding the access point type communication device.

The present invention relates to a device (100) for Wireless-Local-Area-Network (WLAN), -communication to a station, in particular to a vehicle, wherein the device is configured to, determine a disturbance of the WLAN-communication, in particular a Doppler spread; and define a packet-length of the WLAN-communication based on the disturbance.
摘要:
There is provided a device for adapting a wireless transmission rate, comprising a transmitter, a processor adapted to perform the following for a transmission of each of sequential wireless local area network (WLAN) frames by the transmitter: estimate a packet Error Rate (PER) and/or Aggregation Error Rate (AER) for each of physical layer (PHY) rate values (according to frame size), estimate data transmission durations each according to respective PER and/or AER and one of the PHY rate values, and select one of the PHY rate values for adaption of a wireless transmission rate of the transmitter in a following frame according to an analysis of the data transmission durations.
