First Claim
Patent Images
1. A method, comprising:
- by an apparatus,selecting a group of packets for at least one access category;
determining a set of contention parameters based on the at least one access category;
transmitting the selected group of packets by using the determined set of contention parameters;
obtaining information about collision of the transmitted group of packets; and
determining an updated set of contention parameters based on the obtained collision information and a predefined condition;
wherein the set of contention parameters includes a contention window size, and the determining an updated set of contention parameters comprises increasing the contention window size, determining a new access category, and using the minimum of the increased contention window size and the maximum allowed contention window size of the new access category as the updated contention window size.

4. An apparatus, comprising:
-
at least one processor; and at least one memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to; select a group of packets for at least one access category; determine a set of contention parameters based on the at least one access category; transmit the selected group of packets by using the determined set of contention parameters; obtain information about collision of the transmitted group of packets; and determine an updated set of contention parameters based on the obtained collision information and a predefined condition; wherein the set of contention parameters includes a contention window size, and in order to determine an updated set of contention parameters, the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to increase the contention window size, determine a new access category, and use the minimum of the increased contention window size and the maximum allowed contention window size of the new access category as the updated contention window size. - View Dependent Claims (5, 6)

7. A computer program product comprising a non-transitory computer-readable medium bearing computer program code embodied therein for use with a computer, when executed by a processor of the computer, the computer program code comprising:
-
code for selecting a group of packets for at least one access category; code for determining a set of contention parameters based on the at least one access category; code for transmitting the selected group of packets by using the determined set of contention parameters; code for obtaining information about collision of the transmitted group of packets; and code for determining an updated set of contention parameters based on the obtained collision information and a predefined condition; wherein the set of contention parameters includes a contention window size, and the code for determining an updated set of contention parameters comprises code for increasing the contention window size, determining a new access category, and using the minimum of the increased contention window size and the maximum allowed contention window size of the new access category as the updated contention window size. - View Dependent Claims (8, 9)
