Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may signal quasi co-location (QCL) information to a first user equipment (UE). Based on the QCL information, the first UE may determine one or more QCL parameters for communications (such as a receive beam or a transmit beam) for uplink, downlink, or sidelink operations. The first UE may signal the determined QCL parameters to a second UE using a sidelink channel. The second UE may use the QCL parameters to configure a beam for a communication link that the second UE may use to communicate with one or more of the first UE via the sidelink channel, one or more other UEs via additional sidelink channels, or one or more base stations via uplink or downlink transmissions.
