  • Patent number: 11924666
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a first energy level of a demodulation reference signal (DMRS). The UE may measure a second energy level of at least one of a tracking reference signal (TRS) or a synchronization signal block (SSB). The UE may determine, based at least in part on the first energy level and the second energy level, a DMRS signal-to-noise ratio (SNR). The UE may perform, based at least in part on the DMRS SNR, channel estimation for a physical channel associated with a communication to determine an estimated channel. The UE may perform, based at least in part on the estimated channel, demodulation processing for the communication. Numerous other aspects are described.

  • Patent number: 10178561
    Abstract: Examples described herein relate to enhancing data communication performance in a wireless communication network including a first subscription associated with a first radio access technology (RAT) and a second subscription associated with a second RAT, where the wireless communication device uses a same radio frequency (RF) resource to communicate over both the first RAT and the second RAT. The first RAT is used, in part, for data operations while the second RAT is used, in part, for voice operations. During idle state voice operations, the RF resource is reallocated from performing data operations to performing idle state voice operations, causing interruptions in the data operations. The wireless communication device adjusts at least one or a duration and an occurrence of the idle state voice operations to reduce the impact on the data operations.
