    摘要: Aspects of the present disclosure relate to integration of sensing and wireless communications. Wireless communication networks can configure and implement both sensing signals and communication signals. Sensing signals, or sensing reference signals, can be used to determine properties of the environment, and do not carry any information or data for the purpose of communications. Communication signals, on the other hand, are signals that carry information or data between network entities. Sensing agents can be used for both passive and active sensing. Sensing agents may be dedicated devices capable of performing passive sensing, active sensing, or both. Sensing agents can also be existing networks device such as user equipment or transmit receive points. Methodologies described here may be particularly beneficial for half-duplex systems, but could also be implemented in full duplex systems.

    摘要: Systems and methods for DFT-S-SCMA (discrete Fourier Transform-spread-sparse code multiple access) are provided. Input bits are encoded with an SCMA encoder. The output is precoded with a IDFT (inverse DFT) to produce a precoded SCMA block. Multiple precoded SCMA blocks are combined at the input of a DFT. This is done in parallel for multiple sets of SCMA blocks at multiple DFTs. Then, the outputs of the DFTs are combined and OFDM modulated. This approach can be used to improve the PAPR (peak to average power ratio) at the output of the OFDM modulation.

    摘要: Systems and methods for the generation of sensing signals and sensing signal configurations for a wireless communication network are provided. In an embodiment, a sensing node identifier (ID) associated with a network entity is determined. This sensing node ID is used to determine a sensing signal configuration, which includes a resource configuration and a symbol sequence. The resource configuration is selected from a set of physical resources associated with a wireless communication network. The symbol sequence is based on the sensing node ID and is specific to the network entity in the wireless communication network. A sensing signal can be transmitted according to the sensing signal configuration.
