Abstract
Various schemes pertaining to distributed-tone resource unit (dRU) operation for wide bandwidths next-generation wireless local area network (WLAN) systems are described. A communication entity generates at least one dRU or both the at least one dRU and at least one regular resource unit (rRU). The communication entity then communicates wirelessly using the at least one dRU or using the at least one dRU and the at least one rRU in a 160 MHz, 240 MHz, 320 MHz, 480 MHz or 640 MHz bandwidth.
Claims18
A method, comprising:
- generating at least one distributed-tone resource unit (dRU) or both the at least one dRU and at least one regular resource unit (rRU);
- and
- communicating wirelessly using the at least one dRU or using the at least one dRU and the at least one rRU in a 160 MHz, 240 MHz, 320 MHz, 480 MHz or 640 MHz bandwidth,
- wherein the communicating wirelessly comprises communicating wirelessly using the at least one dRU and the at least one rRU:
- in a mixed-distribution mode in which a first dRU or rRU of the at least one dRU and the at least one rRU is used on a 80 MHz segment of the 480 MHz bandwidth, a second dRU or rRU of the at least one dRU and the at least one rRU is used on a 160 MHz segment of the 480 MHz bandwidth, and a third dRU and rRU of the at least one dRU and the at least one rRU is used on a 240 MHz segment of the 480 MHz bandwidth;
- or
- in a mixed-distribution mode in which one of the at least one dRU and the at least one rRU is used on an entirety of the 320 MHz bandwidth and one or more other of the at least one dRU and the at least one rRU are used on:
- one or more 80 MHz segments of the 320 MHz bandwidth;
- or
- one or more 160 MHz segments of the 320 MHz bandwidth;
- or
- a 240 MHz segment of the 320 MHz bandwidth;
- or
- any combination thereof.
11 more elements
An apparatus, comprising:
- a transceiver configured to communicate wirelessly;
- and
- a processor coupled to the transceiver and configured to perform operations comprising:
- generating at least one distributed-tone resource unit (dRU) or both the at least one dRU and at least one regular resource unit (rRU);
- and
- communicating, via the transceiver, using the at least one dRU or using the at least one dRU and the at least one rRU in a 160 MHz, 240 MHz, 320 MHz, 480 MHz or 640 MHz bandwidth,
- wherein the communicating wirelessly comprises communicating wirelessly using the at least one dRU and the at least one rRU:
- in a mixed-distribution mode in which a first dRU or rRU of the at least one dRU and the at least one rRU is used on a 80 MHz segment of the 480 MHz bandwidth, a second dRU or rRU of the at least one dRU and the at least one rRU is used on a 160 MHz segment of the 480 MHz bandwidth, and a third dRU and rRU of the at least one dRU and the at least one rRU is used on a 240 MHz segment of the 480 MHz bandwidth;
- or
- in a mixed-distribution mode in which one of the at least one dRU and the at least one rRU is used on an entirety of the 320 MHz bandwidth and one or more other of the at least one dRU and the at least one rRU are used on:
- one or more 80 MHz segments of the 320 MHz bandwidth;
- or
- one or more 160 MHz segments of the 320 MHz bandwidth;
- or
- a 240 MHz segment of the 320 MHz bandwidth;
- or
- any combination thereof.
