Claim of US Patent No. 10,462,814

1. A method for configuring channel access parameters in a wireless communication system, the method comprising:identifying a first subset of wireless devices and one or more additional subsets of wireless devices in a group of wireless devices, each wireless device of the first subset of wireless devices having a first performance characteristic, and each of the one or more additional subsets of wireless devices having a respective performance characteristic;
generating a channel access parameter set element including a first parameter value in a first parameter field for the first subset of wireless devices, and including a respective parameter value in a respective parameter field for each of the one or more additional subsets of wireless devices; and
transmitting the channel access parameter set element to at least one wireless device of each of the subsets of wireless devices, the transmitting being for setting the first parameter value at each wireless device of the first subset of wireless devices, and the transmitting further being for setting each of the respective parameter values at each wireless device of the respective one or more additional subsets of wireless devices,
wherein the first performance characteristic and the respective performance characteristics are channel access characteristics, and wherein generating the channel access parameter set element further comprises generating identification information in an identification field of the channel access parameter set element, the identification information being identifiable by one or more of the subsets of wireless devices based on one or more of the first subset of wireless devices having the first performance characteristic and each of the one or more additional subsets of wireless devices having the respective performance characteristic.
