Abstract
A communication terminal used in a mobile communication system complying with a carrier sense multiple access scheme is disclosed. The communication terminal includes: a receiving unit configured to receive a wireless packet transmitted by another communication terminal or a base station; a determination unit configured to determine periodic transmission timing of the communication terminal based on determination criterion information included in the wireless packet; and a transmission unit configured to periodically transmit wireless packets to the base station based on the transmission timing.
Claims2
A communication terminal used in a mobile communication system complying with a carrier sense multiple access scheme and including a plurality of communication terminals that transmit wireless packets according to the same periodicity based on a respective different timing, the communication terminal comprising:
- a receiving unit configured to receive a wireless packet transmitted by another communication terminal or a base station;
- a determination unit configured to compare a received signal quality included in the wireless packet that is reported to the base station by the another communication terminal with a received signal quality of the communication terminal so as to determine a transmission timing of the communication terminal based on the result of the comparison;
- and
- a transmission unit configured to periodically transmit wireless packets to the base station based on the transmission timing.
A communication method used on a communication terminal in a mobile communication system complying with a carrier sense multiple access scheme and including a plurality of communication terminals that transmit wireless packets according to the same periodicity based on a respective different timing, the method comprising:
- receiving, at the communication terminal, a wireless packet transmitted by another communication terminal or a base station;
- comparing, at the communication terminal, a received signal quality included in the wireless packet that is reported to the base station by the another communication terminal with a received signal quality of the communication terminal so as to determine a transmission timing of the communication terminal based on the result of the comparison;
- and
- periodically transmitting, at the communication terminal, wireless packets to the base station based on the transmission timing.
