DESIGN CONSIDERATIONS FOR MULTI-LINK AGGREGATION
Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for improved handling of adjacent channel interference in multi-link aggregation scenarios. In accordance with the described techniques, a device may establish a set of wireless links for communication with a second device, the set of wireless links supporting parallel transmission during at least a first duration of a multi-link session, the set of wireless links including at least a first wireless link and a second wireless link. The device may modify a transmission parameter for the first wireless link or a clear channel assessment (CCA) parameter for the second wireless link, or a combination thereof. The device may then perform the CCA procedure on the second wireless link and transmit at least a first portion of the message on the first wireless link based on the modified transmission parameter or modified CCA parameter.
1 . A first wireless device, comprising:
at least one memory; and
at least one processor communicatively coupled with the at least one memory, the at least one processor operable to cause the first wireless device to:
establish a plurality of wireless links between the first wireless device and a second wireless device, the plurality of wireless links supporting parallel transmissions during a multi-link session and including at least a first wireless link and a second wireless link;
configure a first data unit comprising a first portion of a message to be transmitted on the first wireless link and a second data unit comprising a second portion of the message to be transmitted on the second wireless link, the first data unit and the second data unit scheduled to terminate at a same time;
transmit, to the second wireless device based at least in part on the configuring, the first data unit on the first wireless link and the second data unit on the second wireless link; and
receive, on the first wireless link, an acknowledgement or a negative acknowledgement of the first data unit and the second data unit.
