Abstract
The present invention improves the efficiency of transmissions in a multilink. A communication device according to the present invention comprises: a control circuit that controls multilink transmissions on the basis of control information related to the multilink transmissions; and a transmission circuit that performs the multilink transmissions in accordance with the control of the multilink transmissions.
Claims16
A non-Access Point Multi-Link Device (non-AP MLD) including a plurality of affiliated stations (STAs) corresponding to a plurality of links, the non-AP MLD comprising:
- a first receiver, which, in operation, receives a first signal from an AP MLD on a first link and performs channel estimation of the fist link, the first signal including multi-link feedback control information;
- a second receiver, which, in operation, receives a second signal from the AP MLD on a second link and performs channel estimation of the second link;
- control circuitry, which, in operation, determines one or more links used for transmission of feedback information and determines allocation of the feedback information to the one or more links, based on the multi-link feedback control information, and generates the feedback information including results of the channel estimation of the first link and the second link;
- and
- a transmitter, which, in operation, transmits the feedback information on the one or more links.
An Access Point Multi-Link Device (AP-MLD) including a plurality of affiliated stations (STAs) corresponding to a plurality of links, the AP-MLD comprising:
- a first transmitter, which, in operation, transmits a first signal to a non-AP MLD on a first link, the non-AP MLD performing channel estimation of the first link, and the first signal including multi-link feedback control information;
- a second transmitter, which, in operation, transmits a second signal to the non-AP MLD on a second link, the non-AP MLD performing channel estimation of the second link;
- control circuitry, which, in operation, determines one or more links used for reception of feedback information and determines allocation of the feedback information to the one or more links, based on the multi-link feedback control information, the feedback information including results of the channel estimation of the first link and the second link;
- and
- a receiver, which, in operation, receives the feedback information on the one or more links.
A communication method performed by a non-Access Point Multi-Link Device (non-AP MLD) including a plurality of affiliated stations (STAs) corresponding to a plurality of links, the communication method comprising:
- receiving a first signal from an AP MLD on a first link and performing channel estimation of the fist link, the first signal including multi-link feedback control information;
- receiving a second signal from the AP MLD on a second link and performing channel estimation of the second link;
- determining one or more links used for transmission of feedback information and determining allocation of the feedback information to the one or more links, based on the multi-link feedback control information, and generating the feedback information including results of the channel estimation of the first link and the second link;
- and
- transmitting the feedback information on the one or more links.
