Beam updating for multiple transmission reception points

Abstract

Methods, systems, and devices for wireless communications are described. Aspects include configuring a user equipment (UE) to receive control signals from a first transmission reception point (TRP) and a second TRP. A first TRP may transmit a control signal to the UE indicating resources for receiving a medium access control element (MAC-CE), where the control signal includes an indication that associates the MAC-CE with the first TRP. The first TRP may transmit the MAC-CE to the UE which may include a beam update indication for the first TRP. The UE may transmit an acknowledgement to the first TRP based on receiving the MAC-CE. The UE may also transmit an acknowledgment to the second TRP indicating that it has received a beam update indication from the first TRP. In some cases, the first TRP may send a MAC-CE signal to the UE including beam update information for the second TRP.

What is claimed is: 
     
         1 . A method for wireless communication at a user equipment (UE), comprising:
 receiving a configuration message configuring the UE to receive control signals from a first transmission reception point and a second transmission reception point of a transmission reception point cluster;   receiving a first control signal from the first transmission reception point indicating resources for receiving a medium access control element, wherein the first control signal comprises an indication that associates the medium access control element with the first transmission reception point;   receiving the medium access control element based at least in part on receiving the first control signal, wherein the medium access control element comprises a beam update indication for the first transmission reception point; and   transmitting a first acknowledgment to at least the first transmission reception point based at least in part on receiving the medium access control element.
