The embodiments of the present application disclose a sidelink communication method, a terminal device and a network device. The method includes: determining, by a terminal device, a time frequency resource of a physical sidelink control channel (PSCCH) in a first time frequency unit; and receiving or transmitting, by the terminal device, the PSCCH on the time frequency resource. The method, the terminal device, and the network device in the embodiments of the present application help reducing the complexity of PSCCH detection by a terminal device at the receiving end.

A method for determining a resource for a reference signal includes: determining, according to positions of N channel resource units used by a physical channel, R channel resource units from the N channel resource units, where both R and N are integers and 0≤R<N; and sending or receiving reference signals in the R channel resource units.

Systems and methods for wireless communications are disclosed herein. In some arrangements, a method includes switching by a network and a wireless communication device from communicating in a first frequency resource to communicating in a second frequency resource. In response to the switching, the network and the wireless communication device communicate using the second frequency resource.

A terminal is disclosed including a receiver that receives downlink control information including a field that indicates a frequency domain resource assigned to a downlink shared channel; and a processor that, when the terminal is in a connected state and information regarding an initial downlink bandwidth part (BWP) for a cell is provided via a higher layer, determines a bandwidth to use in a determination of a number of bits in the field based on a specified information included in the information regarding the initial downlink bandwidth part (BWP). In other aspects, a radio communication method, a base station, and a system are also disclosed.

The present invention is designed so that, when a CP-OFDM waveform is supported in the UL in addition to DFT-spreading OFDM waveform, transmission of UCI can still be controlled adequately. According to the present invention, a user terminal has a transmission section that transmits uplink control information (UCI), and a control section that controls transmission of the UCI based on a waveform of an uplink (UL) data channel or based on indication information provided via higher layer signaling and/or downlink control information (DCI).

Generally, the described techniques provide for a base station transmitting an indication of a set of one or more available channels to a user equipment (UE). The base station may transmit to the UE a first downlink burst using a first channel and a first frame period. In some cases, the base station may detect interference associated with the first downlink burst, for example, by performing a listen-before-talk (LBT) procedure or through an interference management resources (IMR) procedure in which the base station transmits reference signal signals to the UE that the UE may use to return a report on measured interference. If the base station detects interference, the base station may transmit to the UE an instruction to switch to a second channel and a second frame period, where the second channel may be selected from the set of one or more available channels.

A cross-scheduling resource allocation method for NOMA-based DSS is provided for a first wireless technology carrier and a different second wireless technology carrier co-existing on a same network communication channel. The method includes providing a resource subframe the first carrier within the channel at a specified bandwidth and duration, synchronizing the second wireless carrier to the specified duration within the specified bandwidth, allocating first PRBs within a first portion of the specified bandwidth for the first technology user traffic and second PRBs within a second non-overlapping portion of the specified bandwidth for the second technology user traffic, programming a frequency gap between the first PRBs and the second PRBs, obtaining channel information regarding the target communication channel, and dynamically adjusting the programmed frequency gap based on the obtained channel information.

Aspects of the present application provide methods and devices in a communication network that aid in implementing sounding reference signal (SRS) measurement by multiple cells (i.e. serving cells and non-serving cells, also known as “neighbor cells”) as well as NR LMUs.

Disclosed are a method and an apparatus for communication using fronthaul interfaces. An operation method of a first communication node includes transmitting a section type 8 message #1 including numerology-related information #1; transmitting a section type 9 message #1 including channel information of each of one or more second communication nodes indicated by the section type 8 message #1 and the numerology related information #1, transmitting a section type 8 message #2 including numerology-related information #2 other than the numerology-related information #1; and transmitting a section type 9 message #2 including channel information of each of one or more third communication nodes indicated by the section type 8 message #2 and the numerology-related information #2.

A method, performed by a network node, is disclosed, for configuring resources to be used for Wake-Up Signal, WUS, transmission to a plurality of wireless device groups in the communications network. The method comprises obtaining a number of wireless device groups supported by the communications network. The method comprises allocating, based on the obtained number of wireless device groups supported by the communications network, one or more active resources, out of a set of available resources, for WUS for the number of wireless device groups. The method comprises determining, based on a set of resource configuration criteria, a WUS resource configuration defining a mapping of the wireless device groups to the determined one or more active resources. The method comprises providing, to the wireless device, a set of resource configuration parameters indicative of the determined WUS configuration.
