Abstract

The present disclosure suggests to expand and improve the method of utilizing channel resources in the 802.11be standard by allowing the use of multiple and non-contiguous portions of a channel. Supporting multiple resource units (MRUs) and non-contiguous resource units (RUs) improves the channel utilization by making it more efficient due to enhancing the capability of leveraging the channel selectivity. To this end, a wireless network device for resource allocation is provided and configured to define a non-contiguous MRU in the bandwidth of the channel. The channel includes a plurality of RUs, and the non-contiguous MRU is defined based on non-punctured RUs after puncturing one or more of the RUs of the channel, and/or is defined by aggregating two or more non-adjacent RUs of the channel.

First claim

What is claimed is:

1. A wireless network device for resource allocation, the wireless network device comprising a processor configured to:
define a non-contiguous multiple resource unit (MRU) in a bandwidth of a channel, wherein the channel comprises a plurality of resource units (RUs), and wherein the non-contiguous MRU is defined based on at least one of following: non-punctured RUs after puncturing one or more of the RUs of the channel, or aggregating two or more non-adjacent RUs of the channel;
allocate the non-contiguous MRU to a wireless station; and
transmit a packet to the wireless station utilizing the non-contiguous MRU;
wherein a preamble of the packet comprises information indicating the RUs, wherein the information indicating the RUs comprises at least one of the following: RUs that are used, or the non-punctured RUs, or RUs that are punctured; and
wherein the packet is a physical layer conformance procedure (PLCP) protocol data unit (PPDU), wherein the information is included as a bitmap in a Universal Signaling (U-SIG) field of the preamble of the packet, and wherein the packet is a single-user PPDU or a multi-user PPDU.

2. The wireless network device according to claim 1 , wherein:
the RUs are sub-channels.

3. The wireless network device according to claim 2 , wherein:
the channel comprises one, two, three or four 80 MHz segments, and each 80 MHz segment comprises four 20 Mhz sub-channels.

4. The wireless network device according to claim 1 , wherein:
the RUs each comprise a plurality of contiguous frequency tones.

5. The wireless network device according to claim 4 , wherein:
the frequency tones each have a 78.125 kHz bandwidth.

6. The wireless network device according to claim 1 , wherein:
the non-contiguous MRU comprises one 26-tone RU and one 52-tone RU; or
the non-contiguous MRU comprises one 26-tone RU and one 106-tone RU; or
the non-contiguous MRU comprises one 242-tone RU and one 484-tone RU.

7. The wireless network device according to claim 1 , wherein the non-contiguous MRU comprises at least one of the following:
at least two contiguous parts; or
at least two non-contiguous parts.

8. The wireless network device according to claim 1 , wherein:
the wireless network device is an access point of a wireless network.

9. A method for resource allocation, the method comprising:
defining a non-contiguous multiple resource unit (MRU) in a bandwidth of a channel, wherein the channel comprises a plurality of resource units (RUs), and wherein the non-contiguous MRU is defined based on at least one of following: non-punctured RUs after puncturing one or more of the RUs of the channel, or aggregating two or more non-adjacent RUs of the channel;
allocating the non-contiguous MRU to a wireless station; and
transmitting a packet to the wireless station utilizing the non-contiguous MRU:
wherein a preamble of the packet comprises information indicating the RUs, wherein the information indicating the RUs comprises at least one of the following: RUs that are used, or the non-punctured RUs, or RUs that are punctured; and
wherein the packet is a physical layer conformance procedure (PLCP) protocol data unit (PPDU), wherein the information is included as a bitmap in a Universal Signaling (U-SIG) field of the preamble of the packet, and wherein the packet is a single-user PPDU or a multi-user PPDU.

10. The method according to claim 9 , wherein:
the RUs are sub-channels.

11. The method according to claim 10 , wherein:
the channel comprises one, two, three or four 80 MHz segments, and each 80 MHz segment comprises four 20 Mhz sub-channels.
