DEVICE AND METHOD FOR NON-CONTIGUOUS MULTIPLE RESOURCE UNIT IN A WIRELESS NETWORK
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 comprises a plurality of RUs, and the 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.
1 . A wireless station for resource allocation, the wireless station comprising a processor configured to:
allocate a non-contiguous multiple resource unit (MRU);
wherein the non-contiguous MRU is defined 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 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.
2 . The wireless station according to claim 1 , wherein the RUs are sub-channels.
3 . The wireless station 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 station according to claim 1 , wherein the RUs each comprise a plurality of contiguous frequency tones.
5 . The wireless station according to claim 4 , wherein the frequency tones each have a 78.125 kHz bandwidth.
6 . The wireless station 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 station according to claim 1 , wherein the non-contiguous MRU comprises at least two contiguous and/or non-contiguous parts.
8 . The wireless station according claim 1 , wherein the wireless station is further configured to:
receive a packet from a wireless network device utilizing the MRU.
9 . The wireless station according to claim 8 , wherein the wireless station is further configured to:
receive a preamble of the packet comprising information indicating, for transmitting the packet to the wireless network device utilizing the MRU, the RUs that are used and/or the non-punctured RUs and/or the punctured RUs.
10 . The wireless station according to claim 9 , wherein the packet is a physical layer conformance procedure (PLCP) protocol data unit (PPDU), and the information is included in a Universal Signaling (U-SIG) or an Extremely High Throughput Signaling (EHT-SIG) field of the preamble of the packet.
11 . The wireless station according to claim 10 , wherein:
the packet is a single-user PPDU or a multi-user PPDU; and
the information is included as a bitmap in the U-SIG field of the single-user PPDU or the multi-user PPDU.
12 . The wireless station according to claim 1 , wherein the wireless station is a non-access point (non-AP) station of a wireless fidelity (Wi-Fi) network.
13 . A method for resource allocation, the method comprising:
allocating, by a wireless station, a non-contiguous multiple resource unit (MRU);
wherein the non-contiguous MRU is defined 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 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.
14 . The method according to claim 13 , wherein the RUs are sub-channels.
15 . The method according to claim 14 , wherein the channel comprises one, two, three or four 80 MHz segments, and each 80 MHz segment comprises four 20 MHz sub-channels.
16 . The method according to claim 13 , wherein the RUs each comprise a plurality of contiguous frequency tones.
17 . The method according to claim 16 , wherein the frequency tones each have a 78.125 kHz bandwidth.
18 . The method according to claim 13 , 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.
19 . The method according to claim 13 , wherein the non-contiguous MRU comprises at least two contiguous and/or non-contiguous parts.
20 . The method according to claim 13 , wherein the wireless station is a non-access point (non-AP) station of a wireless fidelity (Wi-Fi) network.
