Problems solved by technology

If the lifetime of a data packet is set to a duration that is too long, the data packet may cause congestion (e.g., at a transmit queue) and / or increase contention (e.g., during wireless communication)

Abstract

An amount of time is determined for a data packet at a medium access control (MAC) layer of a first apparatus to reach an application layer of a second apparatus. A MAC layer lifetime limit of the data packet is set based on the determined amount of time, and the data packet is discarded when the MAC layer lifetime limit is reached. The MAC layer lifetime limit of the data packet includes a duration of time during which the data packet is suitable for transmission. The MAC layer lifetime limit of the data packet may be different from a MAC layer lifetime limit of another data packet associatedwith an access category that is the same as the access category with which the data packet is associated. Various other aspects are provided.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to and the benefit of nonprovisional application Ser. No. 14 / 949,680, filed November 23, 2015, in the United States Patent and Trademark Office. technical field [0003] In general, aspects of the present disclosure relate to wireless communications, and in particular, aspects of the present disclosure relate to setting the lifetime of data packets to minimize congestion and contention. Background technique [0004] A device may communicate with another device in a wireless communication network using various communication protocols. This communication may involve the transmission of various data packets. However, some data packets may become unsuitable for transmission after a certain period of time. In other words, some data packets have a limited lifetime. If the lifetime of a data packet is set to a duration that is too short, the data packet may be discarded prematurely (eg, bef...
