Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a responding station may transmit a first ranging poll via a first bandwidth, the first ranging poll comprising an indication of a second ranging poll and first polling information transmitted with repetitions in a frequency domain based at least in part on serving first initiating stations (I-STAs) configured for communication using the first bandwidth and second I-STAs configured for communication using a second bandwidth that is smaller than the first bandwidth. The responding station may transmit, based at least in part on the indication of the second ranging poll, the second ranging poll over the second bandwidth comprising second polling information. Numerous other aspects are described.

First claim

What is claimed is:

1 . A responding station for wireless communication, comprising:
one or more memories; and one or more processors, coupled to the one or more memories, configured to:
transmit a first ranging poll via a first bandwidth, the first ranging poll comprising an indication of a second ranging poll and first polling information transmitted with repetitions that repeat in a frequency domain based at least in part on serving first initiating stations (I-STAs) configured for communication using the first bandwidth and second I-STAs configured for communication using a second bandwidth that is smaller than the first bandwidth; and
transmit, based at least in part on the indication of the second ranging poll, the second ranging poll over the second bandwidth comprising second polling information.

2 . The responding station of claim 1 , wherein the one or more processors are further configured to receive one or more of:
a first polling response to the first ranging poll from one or more of the first I-STAs; or a second polling response to the second ranging poll from one or more of the second I-STAs.

3 . The responding station of claim 1 , wherein the first bandwidth is greater than 160 megahertz (MHz) and the second bandwidth is 160 MHz or less.

4 . The responding station of claim 1 , wherein a first size of the first bandwidth and a second size of the second bandwidth are integer multiples of a bandwidth size of the repetitions of the first polling information.

5 . The responding station of claim 1 , wherein the one or more processors, to transmit the first ranging poll and transmitting the second ranging poll, are configured to:
transmit the first ranging poll and the second ranging poll within a single ranging window.

6 . The responding station of claim 5 , wherein the single ranging window comprises resources for one or more of:
a first measurement sounding phase, after the first ranging poll and before the second ranging poll, associated with the first I-STAs, a first measurement report phase, after the first ranging poll and before the second ranging poll, associated with the first I-STAs, a second measurement sounding phase, after the second ranging poll, associated with the second I-STAs, or a second measurement report phase, after the second ranging poll, associated with the second I-STAs.

7 . The responding station of claim 1 , wherein the one or more processors, to transmit the first ranging poll, are configured to:
transmit the first ranging poll as a non-high-throughput duplicate physical layer protocol data unit (PPDU).

8 . The responding station of claim 1 , wherein each repetition of the first ranging poll is a non-HT duplicate physical layer (PHY) transmission.

9 . An initiating station (I-STA) for wireless communication, comprising:
one or more memories; and one or more processors, coupled to the one or more memories, configured to:
receive a first ranging poll via a first bandwidth, the first ranging poll comprising an indication of a second ranging poll and first polling information transmitted with repetitions that repeat in a frequency domain based at least in part on a responding station (R-STA) serving first I-STAs configured for communication using the first bandwidth and second I-STAs configured for communication using a second bandwidth that is smaller than the first bandwidth; and
receive, based at least in part on the indication of the second ranging poll, the second ranging poll over the second bandwidth comprising second polling information.

10 . The initiating station of claim 9 , wherein the one or more processors are further configured to transmit one or more of:
a first polling response to the first ranging poll from one or more of the first I-STAs; or a second polling response to the second ranging poll from one or more of the second I-STAs.

11 . The initiating station of claim 9 , wherein the first bandwidth is greater than 160 megahertz (MHz) and the second bandwidth is 160 MHz or less.

12 . The initiating station of claim 9 , wherein a first size of the first bandwidth and a second size of the second bandwidth are integer multiples of a bandwidth size of the repetitions of the first polling information.

13 . The initiating station of claim 9 , wherein the one or more processors, to receive the first ranging poll and receiving the second ranging poll, are configured to:
receive the first ranging poll and the second ranging poll within a single ranging window.

14 . The initiating station of claim 13 , wherein the single ranging window comprises resources for one or more of:
a first measurement sounding phase, after the first ranging poll and before the second ranging poll, associated with the first I-STAs, a first measurement report phase, after the first ranging poll and before the second ranging poll, associated with the first I-STAs, a second measurement sounding phase, after the second ranging poll, associated with the second I-STAs, or a second measurement report phase, after the second ranging poll, associated with the second I-STAs.

15 . The initiating station of claim 9 , wherein the one or more processors, to receive the first ranging poll, are configured to:
receive the first ranging poll as a non-high-throughput duplicate physical layer protocol data unit (PPDU).

16 . A initiating station (I-STA) for wireless communication, comprising:
a memory; and one or more processors, coupled to the memory, configured to:
establish a first link with a responding station (R-STA) via a first radio chain and a second link with the R-STA via a second radio chain;
receive one or more ranging communications of a ranging sequence, receiving the one or more ranging communications comprising:
receive, during a ranging window, the one or more ranging communications via the first link and not via the second link with the R-STA,
receive a multi-user request-to-send (MU-RTS) or buffer status report poll (BSRP) with the one or more ranging communications, the MU-RTS or BSRP indicating resources for the one or more ranging communications associated with one or more of the first link or the second link during the ranging window, or
receive a ranging poll with the one or more ranging communications, the ranging poll indicating resources for the one or more ranging communications associated with one or more of the first link or the second link during the ranging window; and

communicate, before receiving the one or more ranging communications, parameters for the ranging window, wherein the parameters indicate to use the first link and not the second link for receiving the one or more ranging communications.

17 . The initiating station of claim 16 , wherein the one or more processors are further configured to:
communicate with the R-STA, using one or more of the first link or the second link, based at least in part on the ranging sequence.

18 . The initiating station of claim 16 , wherein the one or more processors, to receive the one or more ranging communications, are configured to receive the one or more ranging communications via the first link and not via the second link, and
