Embodiment approach

[0140] 1. A method for communicating small packets in a wireless network, the method comprising: a wireless transmit / receive unit (WTRU) generating a header having one of a medium access control (MAC) and a physical layer convergence protocol (PLCP) In a packet of or more, one or more of the MAC and the PLCP header includes a field.

[0141] 2. The method of embodiment 1 further comprising, if the WTRU has data buffered for transmission, the WTRU including in the field an indication of transmitting data that the WTRU has buffered for transmission Information on at least one of time required for at least one packet and transmission opportunity (TXOP).

[0142] 3. The method of embodiment 1 or 2, further comprising the WTRU transmitting the packet to another WTRU in the wireless network.

[0143] 4. The method of any one of embodiments 1-3 further comprising the WTRU determining based on one of a time required to transmit at least one packet of data that the WTRU has buffered f...

Abstract

A method, a wireless transmit / receive unit (WTRU) and a base station for transferring small packets are described. The WTRU generates a packet that has one or more of a medium access control (MAC) or a physical layer convergence protocol (PLCP) header, the one or more of the MAC or the PLCP header including a field. On a condition that the WTRU has data buffered for transmission, the WTRU includes in the field information that indicates a time or a transmission opportunity (TXOP) needed to transmit at least one packet of data that the WTRU has buffered for transmission. The WTRU transmits the packet to another WTRU in the wireless network. The WTRU receives another packet from the other WTRU with a granted TXO) based on the time needed to transmit the at least one packet of the data that the WTRU has buffered for transmission.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 61 / 700,720, filed September 13, 2013, and U.S. Provisional Application No. 61 / 831,759, filed June 6, 2013, the The contents are hereby incorporated by reference. Background technique [0003] A Wireless Local Area Network (WLAN) is a LAN that connects wireless devices or stations (STAs). In infrastructure basic service set (BSS) mode, a WLAN includes an access point (AP) for the BSS and one or more STAs associated with the AP. An AP may have access or an interface to a Distributed System (DS) or other type of wired or wireless network that carries traffic to and from the BSS. Traffic originating from outside the BSS (but ultimately destined for STAs inside the BSS) can arrive through the AP, which can deliver the traffic to the appropriate STA. Similarly, traffic originating from a STA and destined for a device outside the BSS can be sent to the A...
