Techniques for wireless communications are described. User equipment (UE) may initially configure a set of channel estimation parameters for a set of radio frequency spectrum subbands of a bandwidth part (BWP) of a transmission opportunity (TxOP). In some examples, the UE may identify an unavailable radio frequency spectrum subband within the BWP. Based on the identification, the UE may reconfigure the channel estimation parameters to avoid performing unnecessary channel estimation processes on the unavailable radio frequency spectrum subband. As part of reconfiguring the channel estimation parameters, the UE may set log-likelihood ratio (LLR) values of subcarriers associated with the unavailable radio frequency spectrum subband to a null value, thereby experiencing improvements in efficiency and reliability of channel estimation for the BWP. 描述了用于无线通信的技术。用户设备(UE)最初可以针对传输机会(TxOP)的带宽部分(BWP)的无线电频谱子带集合配置信道估计参数集合。在一些示例中，UE可以识别在BWP内的不可用无线电频谱子带。基于该识别，UE可以重新配置信道估计参数，以避免对不可用无线电频谱子带执行不必要的信道估计过程。作为重新配置信道估计参数的一部分，UE可以将与
