Abstract: The disclosure provides for interference mitigation for wireless signals in unlicensed spectrum. A wireless device may receive a combined signal including a first radio access technology (RAT) signal and a second RAT signal. The wireless device may generate, using a first RAT receiver in a first processing path, a channel estimate for the first RAT signal based on a previously decoded signal of the first RAT. The wireless device may reduce interference to the second RAT signal caused by the first RAT signal, in a second processing path, using the channel estimate. The wireless device may further decode the second RAT signal. The wireless device may remodulate the decoded signal using a transmitter to generate a remodulated second RAT signal. The remodulated second RAT signal may be canceled from the combined signal. The wireless device may decode a remaining portion of the combined signal including the first RAT signal.
Abstract translation: 本公开提供了在无许可频谱中的无线信号的干扰减轻。 无线设备可以接收包括第一无线电接入技术（RAT）信号和第二RAT信号的组合信号。 无线设备可以基于第一RAT的先前解码的信号，使用第一处理路径中的第一RAT接收机生成第一RAT信号的信道估计。 使用信道估计，无线设备可以在第二处理路径中减少由第一RAT信号引起的对第二RAT信号的干扰。 无线设备可以进一步解码第二RAT信号。 无线设备可以使用发射机重新解码解码的信号，以产生重新调制的第二RAT信号。 重新调制的第二RAT信号可以从组合信号中消除。 无线设备可以解码包括第一RAT信号的组合信号的剩余部分。

Abstract: Methods, systems, and devices that support channel estimation reference signals for pre-equalization are described. In some examples, channel state information (CSI) for a link between a user equipment (UE) and another wireless device may be acquired by the UE based on samples of a downlink reference signal transmitted from the UE to the wireless device. Specifically, the wireless device (e.g., an extended reality (XR) device) may obtain samples of the downlink reference signal (e.g., a channel estimation reference signal) and report or indicate (e.g., transmit) the samples to the UE via an uplink transmission. For example, the reference signals may be sampled at the wireless device side, and CSI may be obtained using the samples signaled back to the UE by the wireless device. The UE may perform channel estimation based on the received samples, which may enable transmit pre-equalization of signals sent to the wireless device.

Abstract: Certain aspects of the present disclosure provide techniques for motor-based lens beamformer direction fine tuning. An exemplary method performed by a first apparatus includes communicating one or more transmissions with a second apparatus using a plurality of communication beams, generated by at least one lens beamformer of the first apparatus, having different spatial directions and adjusting, using at least one motor of the first apparatus coupled with the at least one lens beamformer, the different spatial directions of the plurality of communication beams generated by the at least one lens beamformer.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a communication comprising data signaling and superimposed pilots, the superimposed pilots being superimposed on the data signaling transmitted via one or more communication resources of the communication. The UE may decode the data signaling from the communication. The UE may measure one or more channels of one or more beams based at least in part on the superimposed pilots. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may obtain synchronization with a primary cell of a wireless network. The wireless communication device may receive an indication to activate a secondary cell of the wireless network. The wireless communication device may receive a reference signal (RS) of the secondary cell. The wireless communication device may obtain synchronization with the secondary cell based at least in part on an offset between the RS of the secondary cell and a reference time of the primary cell, the reference time based at least in part on the synchronization with the primary cell. The wireless communication device may communicate via the secondary cell based at least in part on the synchronization with the secondary cell. Numerous other aspects are described.

Abstract: Aspects described herein relate to receiving, in a component carrier (CC) configured for a first radio access technology (RAT), a wake-up signal indicating whether to activate communications for each of multiple RATs including a second RAT, and activating, based on the wake-up signal, communications in the first RAT or the second RAT. Other aspects relate to generating and/or transmitting the wake-up signal related to multiple RATs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate, with a primary cell, one or more signals using a first beam that is associated with a first spatial direction. The UE may measure a subset of beams from a set of beams associated with a secondary cell, wherein the subset of beams is selected based at least in part on the first beam or the first spatial direction. The UE may establish a connection with the secondary cell using a second beam from the subset of beams based at least in part on the measurements of the subset of beams. Numerous other aspects are described.

Abstract: A receiving device may identify a mutual information associated with a code block. The receiving device may identify whether the code block is decodable based on the mutual information. The receiving device may skip decoding the code block if the code block is identified as being not decodable. The receiving device may decode the code block if the code block is identified as being decodable. The code block may be identified as being not decodable if the mutual information is less than a second threshold. The code block may be identified as being decodable if the mutual information is greater than the second threshold. The receiving device may identify the second threshold based on an MCS associated with the code block or a code block length of the code block.
