Subcarrier allocations for operation in mixed bandwidth environments
Embodiments of the disclosure provide bandwidth allocation in wireless telecommunications including communication devices that can operate according to different operating bandwidth. The bandwidth allocation can include allocation of subcarrier blocks having specific sizes. The subcarriers blocks can be contiguous within a channel or can be non-contiguous or distributed.
1. A device for communicating a high efficiency (HE) frame for a multi-user, multiple input, multiple output (MU-MIMO) communication session with one or more station devices over one or more channels, the device comprising memory and processing circuitry configured to:
determine a resource allocation in a 80 MHz bandwidth channel, the 80 MHz bandwidth channel having 1024 tones, wherein 23 of the 1024 tones are guard tones, the resource allocation comprising:
a first resource having a first size associated with a first number of first tones, and
a second resource having a second size associated with a second number of second tones;
allocate the first resource to a first station device on the 80 MHz bandwidth channel;
allocate the second resource to a second station device on the 80 MHz bandwidth channel; and
cause to send the HE frame, the HE frame comprising an indication of the resource allocation.
2. The device of claim 1 , wherein the 23 guard tones comprise 11 first guard tones on a first side of the first tones and 12 guard tones on a second side of the first tones, and wherein one or more of the 1024 tones are direct current tones.
3. The device of claim 1 , wherein the first size is different than the second size.
4. The device of claim 3 , wherein the first number of first tones is 26 and the second number of second tones is 52, 106, or 242.
5. The device of claim 1 , wherein the first number of first tones comprises 26 tones, 52 tones, 106 tones, or 242 tones and wherein the second number of second tones is the same as the first number of first tones.
6. The device of claim 1 , further comprising a transceiver configured to transmit and receive wireless signals.
7. The device of claim 6 , further comprising one or more antennas coupled to the transceiver.
8. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
identifying, by a first station device, a high efficiency (HE) frame received in a 80 MHz bandwidth channel, the 80 MHz bandwidth channel having 1024 tones, wherein 23 of the 1024 tones are guard tones, the HE frame comprising:
a first resource allocation of a first resource having a first size associated with a first number of first tones, and
a second resource allocation of a second resource having a second size associated with a second number of second tones;
determining that the first resource is allocated to a second station device in the 80 MHz bandwidth channel; and
determining that the second resource is allocated to the first station device in the 80 MHz bandwidth channel.
9. The non-transitory computer-readable medium of claim 8 , wherein the 23 guard tones comprise 11 first guard tones on a first side of the first tones and 12 guard tones on a second side of the first tones, and wherein one or more of the 1024 tones are direct current tones.
10. The non-transitory computer-readable medium of claim 8 , wherein the first size is different than the second size.
11. The non-transitory computer-readable medium of claim 10 , wherein the first number of tones is 26 and the second number of second tones is 52, 106, or 242.
12. The non-transitory computer-readable medium of claim 8 , wherein the second number of second tones comprises 26 tones, 52 tones, 106 tones, or 242 tones and wherein the second number of second tones is the same as the first number of first tones.
13. A method for communicating a high efficiency (HE) frame for a multi-user, multiple input, multiple output (MU-MIMO) communication session with one or more station devices over one or more channels, the method comprising:
determining, by one or more processors of a first device, a resource allocation in a 80 MHz bandwidth channel, the 80 MHz bandwidth channel having 1024 tones, wherein 23 of the 1024 tones are guard tones, the resource allocation comprising:
a first resource having a first size associated with a first number of first tones, and
a second resource having a second size associated with a second number of second tones;
allocating the first resource to a second station device on the 80 MHz bandwidth channel;
allocating the second resource to a third station device on the 80 MHz bandwidth channel; and
causing to send the HE frame, the HE frame comprising an indication of the resource allocation.
14. The method of claim 13 , wherein the 23 guard tones comprise 11 first guard tones on a first side of the first tones and 12 guard tones on a second side of the first tones, and wherein one or more of the 1024 tones are direct current tones.
