Information receiving apparatus and information transmitting apparatus
First Claim
1. An information receiving apparatus, comprising:
- a wireless transceiver for transmitting and receiving a wireless packet;
a packet generator for generating a wireless packet to be transmitted by the wireless transceiver; and
a controller for controlling the wireless transceiver and the packet generator,wherein the wireless transceiver receives a first wireless packet for data streaming transmission sequentially transmitted by a first information transmitting apparatus followed by a non-transmission period by the first information transmitting apparatus, the first wireless packet containing time-position information indicating whether or not the non-transmission period that follows is assigned to transmission from the information receiving apparatus to the first information transmitting apparatus, andwherein the packet generator generates a second wireless packet for control information transmission transmitted to the first information transmitting apparatus by the wireless transceiver, the second wireless packet containing time-position information indicating the same non-transmission period that the time-position information contained in the first wireless packet received by the wireless transceiver indicates.

Abstract
A transmitting apparatus sequentially transmits a wireless packet PK1 for data streaming transmission with a non-transmission period therebetween to a receiving apparatus. A predetermined proportion of non-transmission periods are assigned to a period for transmitting a wireless packet PK2 for control information transmission from the information receiving apparatus to the information transmitting apparatus. The wireless packets PK1, PK2 contain time-position information indicating a second non-transmission period that is not assigned to the transmission from the receiving apparatus to the transmitting apparatus. The receiving apparatus and another transmitting apparatus different from the transmitting apparatus transmitting the wireless packet PK1 can identify the time position of the second non-transmission period by the time-position information contained in the wireless packets PK1, PK2, and can communicate to each other during the second non-transmission period.

12. An information transmitting apparatus, comprising:
-
a wireless transceiver for transmitting and receiving a wireless packet; a packet generator for generating a wireless packet to be transmitted by the wireless transceiver; and a controller for controlling the wireless transceiver and the packet generator, wherein the wireless transceiver transmits the wireless packet for data streaming transmission having a portion containing time-position information indicating that a non-transmission period by the information transmitting apparatus, which follows the transmission of the wireless packet, is one of (i) a first non-transmission period which is a period assigned to transmission from the information receiving apparatus to the information transmitting apparatus and (ii) a second non-transmission period which is a period not assigned to transmission from the information receiving apparatus to the information transmitting apparatus.

13. An information transmitting apparatus, comprising:
-
a wireless transceiver for transmitting and receiving a wireless packet; a packet generator for generating a wireless packet to be transmitted by the wireless transceiver; and a controller for controlling the wireless transceiver and the packet generator, wherein the wireless transceiver transmits the wireless packet for data streaming transmission containing time-position information indicating whether or not a non-transmission period by the information transmitting apparatus, which follows the transmission of the wireless packet, is assigned to transmission from the information receiving apparatus to the information transmitting apparatus, and when the wireless transceiver does not transmit a wireless packet generated by the packet generator to the information receiving apparatus, the controller causes the wireless transceiver to enter receiving mode during a predetermined period including a time position indicated by the time-position information contained in the packet from the information receiving apparatus. - View Dependent Claims (14)

15. An information transmitting apparatus, comprising:
-
a wireless transceiver for transmitting and receiving a wireless packet; a packet generator for generating a wireless packet to be transmitted by the wireless transceiver; and a controller for controlling the wireless transceiver and the packet generator, wherein the wireless transceiver transmits the wireless packet for data streaming transmission containing time-position information indicating whether or not a non-transmission period by the information transmitting apparatus, which follows the transmission of the wireless packet, is assigned to transmission from the information receiving apparatus to the information transmitting apparatus, and when the wireless packet received by the wireless transceiver from the information receiving apparatus contains a notification of allowing data streaming transmission, the controller causes the packet generator to generate a wireless packet for data streaming transmission, and causes the wireless transceiver to sequentially transmit the wireless packet generated by the packet generator to the information receiving apparatus.

16. An information transmitting apparatus, comprising:
-
a wireless transceiver for transmitting and receiving a wireless packet; a packet generator for generating a wireless packet to be transmitted by the wireless transceiver; and a controller for controlling the wireless transceiver and the packet generator, wherein the wireless transceiver transmits the wireless packet for data streaming transmission containing time-position information indicating whether or not a non-transmission period by the information transmitting apparatus, which follows the transmission of the wireless packet, is assigned to transmission from the information receiving apparatus to the information transmitting apparatus, and when a wireless packet is transmitted during a period corresponding to the time position indicated by the time-position information contained in the wireless packet received by the wireless transceiver from the information receiving apparatus, the controller determines when to transmit, using random backoff. - View Dependent Claims (17, 18)

19. An information transmitting apparatus, comprising:
-
a wireless transceiver for transmitting and receiving a wireless packet; a packet generator for generating a wireless packet to be transmitted by the wireless transceiver; and a controller for controlling the wireless transceiver and the packet generator, wherein the wireless transceiver transmits the wireless packet for data streaming transmission containing time-position information indicating whether or not a non-transmission period by the information transmitting apparatus, which follows the transmission of the wireless packet, is assigned to transmission from the information receiving apparatus to the information transmitting apparatus, and when the amount of information to be transmitted for the data streaming transmission increases or the transmittable bit rate decreases after the wireless packet containing the time-position information is transmitted by the wireless transceiver, the controller adjust the information to be contained in the wireless packet generated by the packet generator so as not to cause the time position of the non-transmission period that is not assigned to the transmission from the information receiving apparatus to the information transmitting apparatus to vary.
