    Abstract: Some embodiments of the present disclosure provide a manner for sensing devices (UEs) to collaborate with base stations to sense an environment. The UEs may obtain observations based on sensing signals transmitted in the environment and provide the observations to a dedicated processing node. The processing node is configured to process the received observations to coherently combine the observations to generate an enhanced observation. In addition to distributing the sensing to multiple UEs, the processing of the observations may also be distributed.

    Abstract: Some aspects of the present disclosure provide a transmission point (e.g., a base station) with an ability to enlist a user equipment to help sense an environment. The transmission point may configure the user equipment to use specific sensing hardware and specific sensing signal parameters, including bandwidth and duration. Furthermore, the transmission point may configure the user equipment to use specific resources to report sensing results to the transmission point.

    Abstract: Some embodiments of the present disclosure relate to the selection of a waveform for an integrated communications and sensing (ICS) signal, where the waveform is suitable for both communication applications and sensing applications. In view of the sensing applications, the waveform selection can be, at least in part, adapted based on capabilities of hardware of nodes involved in the sensing applications. In view of the communication applications, the waveform selection can be, at least in part, adapted based on the extent to which data is to be embedded.

    IPC: G01S13/89

    Abstract: 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.

    Abstract: A framework is provided for generating a MA signal based on modulating at least one first stream of bits using a first modulation type to generate at least one first modulated symbol from each of the at least one first stream of bits, spreading each of the at least one first modulated symbols using a spreading sequence that is specific to a respective first stream of bits to generate a second set of modulated symbols, mapping at least one of the second set of modulated symbols using a resource element mapping and transmitting the mapped second sets of modulated symbols as a MA signal. The spreading of each of the at least one first modulated symbols using a spreading sequence that is specific to a respective first stream of bits may use a layer specific spreading sequence and a layer specific sparsity pattern. The mapping of the at least one of the second set of modulated symbols to a resource element may use a user equipment (UE) specific and/or layer specific spreading sequence. The mapping of the at least one of the second set of modulated symbols to a resource element may use sparse spreading.

    Abstract: 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.

    Abstract: Binary forward error correcting (FEC) encoding is applied to a stream of input bits, to generate a stream of coded bits. The coded bits are mapped to multiple binary streams. In some embodiments, at least one coded bit is mapped to more than one of the binary streams and none of the binary streams are identical to each other. Stream-specific modulations are applied to the binary streams. Non-binary FEC encoding could be applied after the stream-specific modulations.

    Abstract: Embodiments of the present disclosure provide mechanisms for the following procedures: network signaling for user equipment (UE) measurements; UE measurements; UE feedback; feedback adjustment at network nodes; scheduling; Acknowledgements/Negative Acknowledgements; and network-wide planning. Some or all of these mechanisms can be used in implementing distributed open-loop multi-user co-operative multi-point (MU-CoMP) technology as well as other non-CoMP, one-tier or centralized wireless transmission technologies. The mechanisms are in line with proposed no-cell technology for 5G communication networks.
