Embodiments of a Generation Node-B (gNB), User Equipment (UE) and methods for communication are generally described herein. The gNB may allocate a resource pool of physical resource blocks (PRBs) and sub-frames for vehicle-to-vehicle (V2V) sidelink transmissions. The gNB may receive, from a UE, an uplink control message that indicates that the UE requests a V2V sidelink transmission of a prioritized message. The gNB may select, for the V2V sidelink transmission of the prioritized message, one or more PRBs and one or more sub-frames. The gNB may transmit, to the UE and to other UEs, a downlink control message that indicates: the selected PRBs, the selected sub-frames, and that the other UEs are to mute sidelink transmissions in the selected PRBs in the selected sub-frames to enable the V2V sidelink transmission of the prioritized message.

Systems, methods, apparatuses, and computer program products for faster radio frequency (RF) activation are provided. One method may include transmitting by a network node, or receiving by a user equipment, a connection release message for the user equipment, wherein the connection release message comprises an indication for the user equipment to start measuring secondary cells after connection release. The method may then include during or immediately after connection setup or connection resume, receiving by the network node or transmitting by the user equipment, an indication of availability of measurements of the secondary cells.

With advanced compute capabilities and growing convergence of wireless standards, it is desirable to run multiple wireless standards, e.g., 4G, 5G NR, and Wi-Fi, on a single signal processing system, e.g., a system on a chip (SoC). Such an implementation may require simultaneously receiving and transmitting signals corresponding to each wireless standard and also signal processing according to respective requirements. Typical solutions involve providing separate hardware blocks specific to each wireless standard, which in turn requires more area on the SoC and consumes more power. Embodiments of the present disclosure provide a unified hardware that may process signals across different standards in both a transmitting direction and a receiving direction simultaneously.

A wireless access node (e.g. a master eNB (MeNB)) is described for a wireless communication system that comprises a first wireless access network and a second wireless access network supporting a dual connectivity terminal device arranged to communicate with both the wireless access node (MeNB) on the first wireless access network and a second wireless access node (e.g. a secondary eNB (SeNB)) on the second wireless access network is provided. The wireless access node comprises a communication unit and a controller. The controller is operably coupled to the communication unit and configured to control the communication unit to transmit a first message including configuration information for a secondary cell group (SCG) to perform a certain action, to the other base station, and to receive a second message in response to the first message from the other base station, and to control the communication to transmit a third message based on the second message to the terminal, wherein the configuration information includes multimedia broadcast multicast service (MBMS) interest information.

A data transmitting method, a data receiving method, a terminal device, and a network device are provided. The method includes: determining, by a terminal device, a target resource based on a time index and/or configuration information; and transmitting, by the terminal device, data to a network device on the target resource. The terminal device can control resource granularity of the target resource to meet transmission requirements of the terminal device, and can further avoid an actual data transmission process from occurring only on a same frequency domain resource and can further improve the frequency diversity gain in the non-slot transmission. In addition, randomness of interference can be enhanced as much as possible to avoid a same user from always or frequently being in conflict, so when a DMRS of the terminal device conflicts with that of other terminals, performance of user identification can be effectively improved.

A cloud-based Wi-Fi network architecture consisting of a CU and RAUs is proposed as an improvement on the conventional Wi-Fi architecture with traditional access points (APs). In addition, a method for uplink data transmission in a cloud-based Wi-Fi network is proposed. In a conventional Wi-Fi network with independently operating APs, APs close to each other may not be able to utilize the same frequency band efficiently because of significant amounts of interference. However, in a cloud-based Wi-Fi network, the CU coordinates RAUs so that they can operate in the same frequency band by transmitting or receiving signals through the shared wireless medium to improve spectral efficiency. For each frequency band, the proposed system utilizes a diversity combining that combines multiple signals and introduces a single improved signal with high signal-to-noise ratio for uplink transmission in the cloud-based Wi-Fi network. In proposed uplink transmission method for a cloud-based Wi-Fi network, diversity combining is utilized with the immediate acknowledgement (ACK) transmission method that transmits the ACK frame to the client immediately before decoding. The proposed uplink data transmission method mitigates the performance degradation caused by the fronthaul propagation delay between the CU and RAUs, without significant modification of the IEEE 802.11 standard.

Wireless communication apparatus and methods related to wireless communication, for example, device-to-device feedback are described. In aspects, a method of wireless communication may include communicating a sidelink traffic communication using a sidelink communication structure, and communicating an allotting for sidelink feedback using at least one feedback symbol of the sidelink communication structure. In aspects, the method includes communicating, by a first wireless communication device, a sidelink feedback communication using at least one feedback symbol of the sidelink communication structure, wherein the sidelink feedback communication is associated with the sidelink traffic communication. Numerous other aspects are provided.

A method and apparatus for transmitting and receiving signals in a wireless vehicle communication system. The method, performed by a UE, includes obtaining vehicle communication configuration information, determining, for vehicle communication, at least one of whether data is to be relayed, allocated resources, or a waveform, based on the obtained vehicle communication configuration information, and transmitting or receiving signals to or from at least one other UE based on the determination result.

In an aspect, the present disclosure includes a method, apparatus, and non-transitory computer readable medium for wireless communications for a donor node to provide a resource pattern over an integrated access and backhaul (IAB) backhaul. The aspect may include determining, at a central unit (CU) of the donor node, a configuration of a resource pattern for a plurality of IAB-nodes of an IAB network, wherein the configuration of the resource pattern includes a base resource pattern configured with a base periodicity of one or more slots and a plurality of distributed unit (DU) slot format indices within the base periodicity. The aspect may include transmitting, by the CU of the donor node, the resource pattern to one or more of the plurality of IAB-nodes of the IAB network.

A terminal includes a reception unit configured to receive a reference signal of a first RAT (Radio Access Technology); and a control unit configured to decode data of a second RAT using the reference signal.
