    Abstract: Methods, systems, and devices are described for generating a hybrid waveform for data transmission between a transmitting device and a receiving device. The transmitting device may employ an OFDM processing technique to periodically transmit known first pilot symbols mapped from a signal constellation where each signal has equal energy during a first time period and a cyclic prefix based single-carrier (CP-SC) processing technique to transmit data packets and second known pilot symbols during a second time period. Channel estimation is based on first pilot symbols, which are inserted into all subcarriers of OFDM symbol blocks within a specific period. Channel estimation tracking is based on the second pilot symbols interleaved within data packets. The receiving device may be configured to estimate CSI based in part on first pilot symbols and to track the channel estimation based in part on the second pilot symbols in order to provide reliable data detection.

    Abstract: Certain aspects of the present disclosure relate to a hybrid approach for Physical Downlink Shared Channel (PDSCH) Interference Cancellation (IC). In certain aspects, if the PDSCH information is known for a serving cell but not be known for interfering cell(s), a hybrid approach that involves using Codeword-level IC (CWIC) for the serving cell and using Symbol-level IC (SLIC) for the interfering cells may be used for better IC performance. The hybrid IC approach may start with a UE attempting to decode the serving cell PDSCH. If the decode is unsuccessful, the UE may perform CWIC for the serving cell followed by SLIC using the results of the CWIC stage. After the SLIC stage, the UE may attempt to decode the serving cell PDSCH again. The UE may perform multiple operations of this method until the serving cell PDSCH is successfully decoded or a maximum number of iterations is reached.

    Abstract translation: 本公开的某些方面涉及物理下行链路共享信道（PDSCH）干扰消除（IC）的混合方法。 在某些方面，如果PDSCH信息对于服务小区而言是已知的，但对于干扰小区而言是不知道的，则涉及使用码流级IC（CWIC）用于服务小区并使用符号级IC（SLIC ）可以用于更好的IC性能。 混合IC方法可以从尝试对服务小区PDSCH进行解码的UE开始。 如果解码不成功，则UE可以使用CWIC级的结果为服务小区后跟SLIC执行CWIC。 在SLIC阶段之后，UE可以尝试再次对服务小区PDSCH进行解码。 UE可以执行该方法的多个操作，直到服务小区PDSCH成功解码或达到最大次数。

    Abstract: Aspects of the present disclosure describe a guard band signal for communication on a guard band between a first frequency band utilized by a first radio access technology having a first sub-carrier spacing and a second frequency band utilized by a second radio access technology having a second sub-carrier spacing that is a multiple of the first sub-carrier spacing. The guard band signal includes a symbol that is repeated a number of times equal to the multiple. The guard band signal may be generated and transmitted by a transmitting device. The guard band signal may be received and decoded by a receiving device. The guard band signal is interpretable according to a first numerology of the first radio access technology and according to a second numerology of the second radio access technology.
