Abstract: 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.

Abstract: A method of performing wireless communication includes accumulating, by a user equipment (UE) during initial cell search, samples of received data over a maximum front-end bandwidth of the UE. The method also includes splitting the samples into smaller, non-overlapping spectrum chunks, and performing correlation-based detection on one or more of the smaller, non-overlapping chunks. The method further includes detecting a wireless communication system based on results of the correlation-based detection.

Abstract: Methods, systems, and devices for wireless communications are described to enable a base station to configure additional reference signals, which may be referred to as configured reference signals, to include in a transmission to a user equipment (UE). The UE may transmit a report to the base station, indicating a UE capability for supporting configured reference signals, and the base station may configure a pattern for the configured reference signals. The base station may transmit an indication of the pattern to the UE, where the indication may include one or more characteristics associated with the configured reference signals. The base station may transmit the configured reference signals to the UE according to the pattern, along with one or more baseline reference signals, within an associated transmission. The UE may use the configured reference signals and the baseline reference signals to receive a transmission from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may retune from a first narrowband carrier to a second narrowband carrier. The UE may determine to retune in one or more symbols of either a first narrowband subframe or a second narrowband subframe based on the number of symbols for the UE to retune and a number of other factors. The other factors may include the start symbol of a downlink channel scheduled in the second narrowband subframe, the number of antenna ports configured for the UE, hybrid automatic repeat request (HARQ) identifier (ID), coding rate or effective coding rate, among others. The UE may determine to retune in the first narrowband subframe, the second narrowband subframe, or in both subframes in order to utilize reference signals transmitted to the UE and reception of all downlink messages scheduled for the UE.
