Abstract

Implementations of the present disclosure relate to resource unit (RU) assignment to combat frequency selective fading. A method comprises determining, at an access point (AP), a plurality of channel qualities of a plurality of resource units (RUs) for a client. The plurality of RUs are configured to be available for communications with a plurality of clients comprising the client. The method further comprises determining, from the plurality of RUs, a target RU for the client based at least in part on the plurality of channel qualities. The target RU is to be used by the client for a following transmission with the AP. A target RU with good channel quality will be assigned to the client, thus the transmission and overall system performance will be enhanced.

Dependent claims

A method comprising:

determining, at an access point (AP), a plurality of channel qualities of a plurality of resource units (RUs) for a client, the plurality of RUs being configured to be available for communications with a plurality of clients comprising the client;
determining, from the plurality of RUs, a target RU for the client based on comparisons between the plurality of channel qualities and a threshold quality set for the client buff:
in accordance with a determination that more than one RU of the plurality of RUs has a channel quality exceeding the threshold quality, determining a candidate RU set for the client from the more than one RU having the channel quality exceeding the threshold quality, the candidate RU set comprising at least one RU;
and
selecting a candidate RU from the candidate RU set as the target RU for the client by determining the number of candidate clients for each RU in the candidate RU set, a respective channel quality of the RU for a candidate client exceeding a threshold quality set for the candidate client;
and
in accordance with a determination that the number of candidate clients for a particular RU in the candidate RU set is less than or equal to the numbers of candidate clients for other RUs in the candidate RU set, selecting the particular RU as the target RU for the client;
wherein the target RU is to be used by the client for a following transmission with the AP.

A method comprising:

performing, at a client, transmissions with an access point (AP) using a plurality of resource units (RUs), the plurality of RUs configured to be available for communications with a plurality of clients comprising the client;
receiving, from the AP, indication information indicative of a target RU from the plurality of RUs for the client based on comparisons between a plurality of channel qualities of the plurality of RUs and a threshold quality set for the client;
wherein according to a determination that more than one RU of the plurality of RUs has a channel quality exceeding the threshold quality, a candidate RU set is determined for the client from the more than one RU having the channel quality exceeding the threshold quality, the candidate RU set comprising at least one RU;
wherein a candidate RU is selected from the candidate RU set as the target RU for the client by determining the number of candidate clients for each RU in the candidate RU set, a respective channel quality of the RU for a candidate client exceeding the threshold quality set for the candidate client;
and
wherein according to a determination that the number of candidate clients for a particular RU in the candidate RU set is less than or equal to the numbers of candidates clients for other RUs in the candidate RU set, the particular RU is selected as the target RU for the client;
and
performing a following transmission with the AP using the target RU.

5 more elements

A communication device comprising:

at least one processor;
and
a memory coupled to the at least one processor, the memory storing instructions to cause the at least one processor to implement acts comprising:
determining a plurality of channel qualities of a plurality of resource units (RUs) for a client, the plurality of RUs being configured to be available for communications with the client and at least one further client;
and
determining, from the plurality of RUs, a target RU for the client based on comparisons between the plurality of channel qualities and a threshold quality set for the client and the at least one further client by:
in accordance with a determination that more than one RU of the plurality of RUs has a channel quality exceeding the threshold quality, determining a candidate RU set for the client and the at least one further client from the more than one RU having the channel quality exceeding the threshold quality, the candidate RU set comprising at least one RU;
and
selecting a candidate RU from the candidate RU set as the target RU for the client and the at least one further client by determining the number of candidate clients for each RU in the candidate RU set, a respective channel quality of the RU for a candidate client exceeding a threshold quality set for the candidate client;
and
in accordance with a determination that the number of candidate clients for a particular RU in the candidate RU set is less than or equal to the numbers of candidate clients for other RUs in the candidate RU set, selecting the particular RU as the target RU for the client and the at least one further client, the target RU having a channel quality higher than a threshold quality set for the client and the at least one further client,
wherein the target RU is to be used by the client and the at least one further client for a following transmission with the communication device.
