Methods, systems, and devices for wireless communications are described. A user equipment (UE) may decode a first signal received over a broadcast channel during a first synchronization signal block (SSB) occasion to identify a first payload, and determine one or more expected changes between the first payload and a second payload of a second signal expected to be received over the broadcast channel during a second SSB occasion. The UE may update the first payload with the one or more expected changes to determine an updated first payload, and encode the updated first payload as an updated first signal. The UE may receive the second signal over the broadcast channel during the second SSB occasion, and apply the second signal and the updated first signal to a tracking procedure for the UE.

Techniques for performing tracking using a physical broadcast channel

In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications at a user equipment (UE) for measuring one or more synchronization signal block (SSB) beams from a network entity; selecting a highest rated SSB beam from the one or more SSB beams based on one or more selection factors; transmitting, to the network entity, a beam report including an identification of the highest rated SSB beam; initiating a timer in response to transmitting the beam report; determining whether a media access control (MAC) control element (CE) is received from the network entity before expiration of the timer; and performing beam switching from a current SSB beam to the highest rated SSB beam based on a determination that the MAC CE is not received from the network entity before expiration of the timer.

Techniques for handling a radio link failure in a wireless communication system

Aspects of the disclosure relate to minimizing the number of antenna array modules on a wireless communication device utilized in forming beam pair links (BPLs) based on beam measurements obtained on each of a plurality of receive beams for each of a plurality of transmit beams. For at least one BPL, the wireless communication device selects a different receive beam that results in at least one fewer active antenna array module. In some examples, the different receive beam selected for a BPL has a beam measurement value within a predefined variance from a beam measurement value of an original receive beam for the BPL. In addition, the wireless communication device can confirm that the beam measurement values of both the original and different receive beams satisfy a minimum beam measurement value before switching the BPL to the different receive beam. Other aspects, features, and embodiments are also claimed and described.
