Wireless communication systems, including systems, apparatuses, and methods for measurement capability and configuration on shared spectrum terrestrial networks (TNs) and non-terrestrial networks (NTNs) are disclosed. A user equipment (UE) includes a transceiver and a processor configured to cause the UE to receive, via the transceiver, control signaling indicating a neighbor cell measurement configuration for a radio frequency (RF) spectrum band utilized by both a TN device and an NTN device to serve UEs. The processor is further configured to receive, via the transceiver and according to the indicated neighbor cell measurement configuration, reference signals of the RF spectrum band from the TN device and from the NTN device. The processor is further configured to perform a mobility operation based on the reference signals from the TN device, the reference signals received from the NTN device, or both.

Provided are an apparatus and method of wireless communication. A method of wireless communication by a user equipment (UE) includes determining a span combination including a first parameter and a second parameter for a subcarrier spacing higher than 60 kHz, where the first parameter is a distance between two consecutive spans and the second parameter is a span length. This can address problems in the prior art of providing channel access related indication for more than one scheduled uplink transmission by a same downlink control indicator (DCI) in a shared spectrum, reducing signaling overhead, providing good communication performance, and / or providing high reliability.

Methods and apparatus for BWP and SUL operations in wireless systems, particularly in systems using shared spectrum, are described herein. In one embodiment, a wireless transceiver unit (WTRU) receives information regarding an imminent Channel Occupancy Time (COT) and can use the received information to determine at least one resource for the operation of the WTRU during the COT. In one embodiment, a WTRU operating in a wireless network can transmit data on a first uplink carrier. It can trigger a switch from the first uplink carrier to a second uplink carrier based on at least one condition of the network and transmit data on the second uplink carrier.

System and Methods for configuring shared spectrum cellular systems with Physical Resource Block Blanking and related operations for the control and data channels and reference signals within the carrier channel bandwidth. The systems are configured for protection in the carrier bandwidth to avoid victim interference mitigation.

Various aspects of this disclosure relate to wireless communications, and more specifically to techniques for measurement and initial access for sharing spectrum among mobile network operators.

Methods, systems, and devices for wireless communications are described, in which devices may operate in a frame based equipment (FBE) mode for sidelink communications. One or more fixed frame period (FFP) configurations may be used by different sidelink devices, and a first device (e.g., a first user equipment UE) ) may transmit to one or more other devices an indication of a FFP configuration for sidelink communications. The FFP configuration may include an idle period configuration that is coordinated across multiple devices for initiation of a channel access procedure. Alternatively different sidelink devices may have different FFP configurations, and a joint pattern may be provided for performing the channel access procedure at each of the sidelink devices.

This invention provides a millimeter-wave spectrum resource sharing method, resource pool reflector, device, and medium, relating to the field of communication technology. The method includes: acquiring the shareable spectrum resources available from each millimeter-wave base station; upon receiving a resource request from a macro base station, acquiring the location grid of the user equipment (UE) and its associated target base station from the resource request; if the target base station has available spectrum resources, generating resource allocation information based on the available spectrum resources and sending it to the macro base station; and the macro base station instructing the UE to establish a communication connection with the target base station based on the resource allocation information, thereby achieving spectrum resource sharing. By sharing the idle resources of millimeter-wave base stations with base stations requiring additional wireless resources, interference between different devices accessing broadband spectrum heterogeneously in millimeter-wave mobile communication networks can be resolved, reducing problems such as terminals being unable to use millimeter-wave broadband networks in weak signal areas and communication interruptions caused by differences in the hardware performance of millimeter-wave transceivers from different terminals.

The application provides a speech coding adjustment method and device in dynamic spectrum sharing, electronic equipment and storage medium, and relates to the technical field of wireless communication. The method comprises the following steps: receiving a notification of whether a next first preset time length occupies a shared frequency band sent by a long term evolution (LTE) network at a current time; in response to the notification including that the LTE network needs to occupy the shared frequency band in the next first preset time length, correcting channel quality information, and adjusting a speech coding rate based on the corrected channel quality information. At least the problem that the LTE system has high priority and occupies the shared spectrum for a long time when the traffic volume is large, resulting in poor voice service quality of the UMTS system, is solved. The application is suitable for spectrum sharing optimization, voice service optimization and the like.

Systems and methods a system for generating Low-Density Parity-Check (LDPC) code for enabling multiple simultaneous users in Asynchronous Scrambled Coded Multiple Access (ASCMA). The system includes transmitter node with source endpoints, each equipped with an encoder unit generating LDPC codeword bits from information bits. An encoder aggregates LDPC codeword bits with replicated information bits to create an aggregated sequence. A modulator unit modulates the sequence into a waveform for transmission over a shared spectrum access channel. The transmitted waveform is asynchronously sent to a receiver node, which includes a gateway linked to destination endpoints. The receiver unit captures a noise-corrupted version of the waveform, and a decoder unit, using soft-input and soft-output techniques, decodes information bits. A Multi-User Interference (MUI) estimator cancels interference levels, allowing the decoder to recover the original information bits associated with the source endpoints.
