Abstract
[Object] To reduce the frequency of the occurrence of the transmission collision of frames. [Solution] A communication device, including: a receiving unit configured to receive a frame transmitted by another terminal; a length information acquiring unit configured to acquire length information related to the frame from the received frame; and a transmission frame deciding unit configured to decide a length of a transmission frame on the basis of the acquired length information.
Claims11
A communication device, comprising:
- receiving circuitry configured to receive a frame;
- transmitting circuitry;
- and
- processing circuitry configured to:
- determine whether or not the received frame is a signal transmitted from another terminal belonging to another network different from a network to which the communication device belongs on a basis of BSS Color information included in the received frame;
- acquire length information related to the frame from the received frame;
- decide a length of a transmission frame on a basis of the acquired length information;
- determine a reception power of the signal transmitted from the other terminal belonging to the other network;
- control transmission power of the transmission frame in accordance with the determined reception power such that:
- the transmission power of the transmission frame is decreased in a case in which the determined reception power is above a threshold value, or
- the transmission power of the transmission frame is increased in a case in which the determined reception power is below the threshold value;
- and
- transmit the transmission frame in accordance with the controlled transmission power.
A communication method by a communication device including a transceiver and a processor, the method comprising:
- receiving, by the processor, a frame;
- determine whether or not the received frame is a signal transmitted from another terminal belonging to another network different from a network to which the communication device belongs on a basis of BSS Color information included in the received frame;
- acquiring, by the processor, length information related to the frame from the received frame;
- deciding, by the processor, a length of a transmission frame on a basis of the acquired length information;
- determining a reception power of the signal transmitted from the other terminal belonging to the other network;
- controlling transmission power of the transmission frame in accordance with the determined reception power such that:
- the transmission power of the transmission frame is decreased in a case in which the determined reception power is above a threshold value, or
- the transmission power of the transmission frame is increased in a case in which the determined reception power is below the threshold value;
- and
- transmitting the transmission frame in accordance with the controlled transmission power.
A non-transitory computer readable program product containing a program that causes a processor to:
- receive a frame;
- determine whether or not the received frame is a signal transmitted from another terminal belonging to another network different from a network to which the communication device belongs on a basis of BSS Color information included in the received frame;
- acquire length information related to the frame from the received frame;
- decide a length of a transmission frame on a basis of the acquired length information;
- determine a reception power of the signal transmitted from the other terminal belonging to the other network;
- control transmission power of the transmission frame in accordance with the determined reception power such that:
- the transmission power of the transmission frame is decreased in a case in which the determined reception power is above a threshold value, or
- the transmission power of the transmission frame is increased in a case in which the determined reception power is below the threshold value;
- and
- transmit the transmission frame in accordance with the controlled transmission power.
