Front-End for Full-Duplex Below Noise Radar in a Wireless Communication Device
A wireless device is configured to transmit radar signals at extremely low spectral density so that the receiver can be operated at the same time without saturating and thereby enabling full-duplex operation. To achieve sufficient range, beamforming is used together with a very long correlation time for detection of the radar signal, in which case the receiver can resolve backscattered or reflected radar signals far below the noise floor, while the bandwidth of the transmitted radar signal can be very high. The wide bandwidth enables the wireless device to maintain a low power spectral density while increasing output power, and also increase the depth resolution. The extremely low power spectral density even in the transmission beam direction makes the probability that communication will be disturbed very low. The high bandwidth calls for digital filters for both transmitted and received signals to equalize the radar frequency response characteristics of the radio unit.
Systems and method provide for uplink carrier aggregation (UL CA) that is configured for a User Equipment (UE), and transmissions on multiple UL carriers by one power amplifier (PA). When a base station (e.g., a gNB) indicates the UE should switch its UL waveform from Cyclic-Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) to Discrete Fourier Transform Spread OFDM (DFT-S-OFDM) for Physical Uplink Shared Channel (PUSCH) transmission in one or more UL carriers, the base station expects that the UE transmit power on a particular carrier can be increased, the carrier for which a UL coverage issue (e.g., low signal strength, signal to noise ratio, interference, etc.) is found. UL waveform switching from CP-OFDM to DFT-S-OFDM can improve the lower bound of PCMAX, namely the total UE transmit power on UL carriers of intra-band CA.
A method, system and apparatus are disclosed. A network node configured for dynamic spectrum sharing of a first RAT and a second RAT is provided. The network node is configured to determine a first number of failed scheduling requests associated with the first RAT, determine a resource configuration for the first RAT and the second RAT for a first time period based on the first number of failed scheduling requests, and schedule at least one transmission for the first time period with at least one wireless device based on the resource configuration.
The embodiments herein relate to suppressing N1N2 message transfer for failure notification. In some embodiments, a method is performed by a first network function implementing an Access and Mobility Management Function (AMF). The method may include the step of paging a User Equipment (UE). The method may further include the step of transmitting, to a second network function implementing a network function consumer, a failure notification message including a first parameter indicating a retry-after time, in response to a failure in the paging. A transfer of message from the second network function to the first network function may be suppressed during the retry-after time. With the embodiments, by defining a retry-after timer in the failure notification, the unnecessary signal exchange between the network function service consumer and the AMF before the timeout of the retry-after timer may be reduced.

The threshold depends on whether the PDSCH is received in a bandwidth that is larger than a reduced bandwidth associated with RedCap wireless devices.
