  • Publication number: 20240187162
    Abstract: Systems and methods are disclosed for handling a limited set of Path Loss Reference Signals (PL-RSs). In one embodiment, a method performed by a wireless communication device comprises determining a subset of a set of activated uplink (UL) transmission configuration indicator (TCI) states or activated joint or downlink (DL) TCI states for the wireless communication device for which the wireless communication device is to monitor associated pathloss reference signals. The method further comprises monitoring the pathloss reference signals for the subset of the set of activated UL TCI states or activated joint or DL TCI states. In this manner, the wireless communication device is enabled to have a well-defined framework for how to handle uplink output power when the network indicates a switch to a new UL state or new joint or DL TCI state for which the UE is not monitoring a pathloss reference signal.

  • Publication number: 20240163040
    Abstract: Systems and methods for handling serving and non-serving cells having different frequency domain reference points for reference signal sequence generation are disclosed. In one embodiment, a method performed by a wireless communication device (WCD) comprises obtaining information about a frequency domain reference point to be used for one or more reference signals on a non-serving cell of the WCD and applying the information about the frequency domain reference point to be used for the one or more reference signals on the non-serving cell of the WCD to receive or transmit one or more reference signals on the non-serving cell of the WCD. In this manner, inter-cell operation is enabled for a UE for cases when a network deployment uses different reference points for reference signal sequence generation for different cells.

  • Publication number: 20240155588
    Abstract: Embodiments include a communication system including host computer, base station, and UE, and methods therein. The host computer provides user data and initiates a transmission carrying the user data to the UE via a cellular network comprising the base station. The UE receives, from the base station, an indication of an active bandwidth part (BWP), which is of size NBWP,1size in number of frequency-domain resource blocks (RBs). The UE receives an indication of one or more frequency-domain RBs assigned within the active BWP for carrying the user data. The indication is encoded based on a size NBWP,2size (<size NBWP,1size) of another BWP than the active BWP. The UE decodes the indication to obtain a starting virtual RB and a length of contiguously allocated RBs within the active BWP. The starting virtual RB is encoded with resolution K RBs, with K being based on a ratio of sizes NBWP,1size and NBWP,2size.

  • Patent number: 11978466
    Abstract: Systems, methods, and apparatuses to restore degraded speech via a modified diffusion model are described. An exemplary system is specially configured to train a diffusion-based vocoder containing an upsampler, based on pairing original speech x and degraded speech mel-spectrum mT samples; train a deep convoluted neural network (CNN) upsampler based on a mean absolute error loss to match the estimated original speech {circumflex over (x)}? outputted by the diffusion-based vocoder by extracting the upsampler, generating a reference conditioner, and generating a weighted altered conditioner cTn?. The system further optimizes speech quality to invert non-linear transformation and estimate lost data by feeding the degraded mel-spectrum mT through the CNN upsampler and feeding the degraded mel-spectrum mT through the diffusion-based vocoder. The system then generates estimated original speech {circumflex over (x)}? based on the corresponding degraded speech mel-spectrum mT. Other related embodiments are described.
