Method for transmitting and receiving data bi-directionally during allocated time and wireless device using the same
First Claim
1. A wireless device comprising:
- a Physical Layer (PHY) module for receiving a Medium Access Control (MAC) frame through a wireless medium;
a MAC module for reading a value of a first field in the received MAC frame, wherein the first field specifies whether there is more data to be sent;
a transmission rights determining module for determining that a transmission right has been passed to the wireless device if the value of the first field is a first bit and a channel is idle during a predetermined threshold time after reception of the MAC frame, wherein the first bit represents that there is no more data to be sent; and
a control module that, if the transmission right has been passed to the wireless device and there is data to be sent to another device that has sent the MAC frame, controls the operation of the MAC module and the PHY module to allow transmission of a MAC second frame containing the data to be sent.

Abstract
A method and device for bi-directionally transmitting and receiving data during an allocated time period are provided. The device includes a Physical Layer (PHY) module receiving a Medium Access Control (MAC) frame through a wireless medium, a MAC module reading a value of a first field in the received MAC frame, wherein the first field specifies whether there is more data to be sent, and a transmission rights determining module determining that a transmission right has been passed to the wireless device when the value of the first field is a first bit and a channel is idle during a predetermined threshold time after reception of the MAC frame, wherein the first bit represents that there is no more data to be sent.

8. A method for bi-directionally transmitting and receiving data during an allocated time period, the method comprising:
-
receiving a Medium Access Control (MAC) frame through a wireless medium; reading a value of a first field in the received MAC frame, the first field specifying whether there is more data to be sent; determining that a transmission right has been passed if the first field is set to a first bit and a channel is idle during a predetermined threshold time after reception of the MAC frame, wherein the first bit represents that there is no more data to be sent; and if the transmission right has been passed and there is data to be sent to a device that has sent the MAC frame, transmitting a second MAC frame containing the data to the device. - View Dependent Claims (9, 10, 11, 12, 13, 14)
