Communication apparatus, control method for communication apparatus, and storage medium
A communication apparatus capable of multiple link communication compliant with an IEEE 802.11 series standard, decides a first link, from among a plurality of links established with a communication partner apparatus, which is to be a link with prohibited transmission by the communication partner apparatus, and a transmission prohibition period for the first link, and transmits, using the first link, a first frame including information relating to transmission prohibition for the first link. The communication apparatus transmits, using a second link different from the first link among the plurality of links, a second frame including information relating to transmission prohibition for the first link, before the transmission prohibition period starts.
1 . A communication apparatus, comprising:
a decision unit configured to decide a first link, from among a plurality of links established with a communication partner apparatus, wherein transmission, by the communication partner apparatus, via the first link is to be prohibited, and a transmission prohibition period for the first link; and
a transmission unit configured to transmit, using a second link different from the first link among the plurality of links, a first frame including information of the transmission prohibition period for the first link, before the transmission prohibition period starts, wherein the information of the transmission prohibition period for the first link is information represented using TBTT (Target Beacon Transmission Time) of the second link as a reference.
2 . The communication apparatus according to claim 1 , wherein
the decision unit decides at least one the first link or the transmission prohibition period based on an instruction from a user.
3 . The communication apparatus according to claim 1 , wherein
the transmission prohibition period is a periodic time period.
4 . The communication apparatus according to claim 1 , wherein
the first frame further includes information relating to a start timing of the transmission prohibition period for the first link.
5 . The communication apparatus according to claim 1 , wherein
the communication apparatus is a communication apparatus capable of multiple link communication compliant with an IEEE 802.11 series standard.
6 . The communication apparatus according to claim 1 , wherein
the transmission unit transmits a second frame including information relating to cancellation of transmission prohibition for the first link after the transmission prohibition period has elapsed.
7 . The communication apparatus according to claim 1 , wherein
the first frame is a Probe Response frame or a Beacon frame.
8 . The communication apparatus according to claim 6 , wherein
the second frame is a Probe Response frame, a Beacon frame, or a FILS (Fast Initial Link Setup) Discovery frame.
9 . The communication apparatus according to claim 1 , wherein
the communication apparatus is an AP MLD (Access Point Multi-Link Device).
10 . The communication apparatus according to claim 1 , wherein
the information of the transmission prohibition period for the first link is included in a Quiet element that is transmitted from the communication apparatus to the communication partner apparatus.
11 . The communication apparatus according to claim 10 , wherein
the Quiet element includes a Quiet Count field, a Quiet Offset field, and a Quiet Duration field.
12 . A control method for a communication apparatus, the control method comprising:
deciding a first link, from among a plurality of links established with a communication partner apparatus, wherein transmission, by the communication partner apparatus, via the first link is to be prohibited, and a transmission prohibition period for the first link; and
transmitting, using a second link different from the first link among the plurality of links, a first frame including information of the transmission prohibition period for the first link, before the transmission prohibition period starts, wherein the information of the transmission prohibition period for the first link is information represented using TBIT (Target Beacon Transmission Time) of the second link as a reference.
13 . A non-transitory computer-readable storage medium storing a program for a communication apparatus that when executed by the communication apparatus causes the communication apparatus to execute a control method for the communication apparatus comprising:
deciding a first link, from among a plurality of links established with a communication partner apparatus, wherein transmission, by the communication partner apparatus, via the first link is to be prohibited, and a transmission prohibition period for the first link; and
transmitting, using a second link different from the first link among the plurality of links, a first frame including information of the transmission prohibition period for the first link, before the transmission prohibition period starts, wherein the information of the transmission prohibition period for the first link is information represented using TBTT (Target Beacon Transmission Time) of the second link as a reference.
