Abstract
Disclosed is a wireless communication terminal wirelessly communicating with a base wireless communication terminal. The wireless communication terminal comprises: a transceiver; and a processor. The processor transmits low latency traffic configured as traffic for low latency transmission in a limited service period, or a response to the low latency traffic, and in the limited service period, transmission except for the transmission of the low latency traffic and the transmission of the response to the low latency traffic is limited.
Claims15
A wireless communication terminal for wirelessly communicating with a base wireless communication terminal, the wireless communication terminal comprising:
- a transceiver;
- and
- a processor configured to:
- terminate a transmission opportunity (TXOP) before a start of a restricted service period except when a frame exchange for low latency traffic is ongoing,
- perform a channel access procedure including obtaining a random integer within a contention window,
- transmit low latency traffic configured as traffic for low latency transmission or a response to the low latency traffic within the restricted service period,
- restrict transmission, except for transmission of the low latency traffic and transmission of the response to the low latency traffic, within the restricted service period, and
- perform the channel access procedure again when the channel access procedure is completed before the start of the restricted service period, wherein the wireless communication terminal abandons transmission upon determination that a frame exchange fails to be completed before the start of the restricted service period, and wherein performing the channel access procedure again includes:
- maintaining a size of the contention window used for the completed channel access procedure without change, and
- obtaining a new random integer within the contention window.
A method of operating a wireless communication terminal for wirelessly communicating with a base wireless communication terminal, the method comprising:
- terminating a transmission opportunity (TXOP) before a start of a restricted service period except when a frame exchange for low latency traffic is ongoing;
- performing a channel access procedure including obtaining a random integer within a contention window;
- transmitting low latency traffic configured as traffic for low latency transmission or a response to the low latency traffic within the restricted service period;
- restricting transmission, except for transmission of the low latency traffic and transmission of the response to the low latency traffic, within the restricted service period;
- and
- performing the channel access procedure again when the channel access procedure is completed before the start of the restricted service period, wherein the wireless communication terminal abandons transmission upon determination that a frame exchange fails to be completed before the start of the restricted service period, and wherein performing the channel access procedure again includes:
- maintaining a size of the contention window used for the completed channel access procedure without change, and
- obtaining a new random integer within the contention window.
A method comprising:
- providing a wireless communication terminal for wirelessly communicating with a base wireless communication terminal, the wireless communication terminal comprising:
- a transceiver;
- and
- a processor configured to:
- terminate a transmission opportunity (TXOP) before a start of a restricted service period except when a frame exchange for low latency traffic is ongoing,
- perform a channel access procedure including obtaining a random integer within a contention window,
- transmit low latency traffic configured as traffic for low latency transmission or a response to the low latency traffic within the restricted service period,
- restrict transmission, except for transmission of the low latency traffic and transmission of the response to the low latency traffic, within the restricted service period, and
- perform the channel access procedure again when the channel access procedure is completed before the start of the restricted service period, wherein the wireless communication terminal abandons transmission upon determination that a frame exchange fails to be completed before the start of the restricted service period, and wherein performing the channel access procedure again includes:
- maintaining a size of the contention window used for the completed channel access procedure without change, and
- obtaining a new random integer within the contention window.
