This application discloses a session management method, a network device, and a communications system. According to embodiments of the present invention, an intermediate session management entity is selected based on UE location information and PDU session requirement information. In this way, an intermediate session management entity near UE can provide a service for a PDU session, and a delay of data transmission is reduced. In addition, the intermediate session management entity selects a user plane entity based on the UE location information and the PDU requirement information, and the intermediate session management entity is responsible for managing user plane entities within a specified area, and does not need to manage user plane entities in the entire PDU session, thereby reducing management complexity.

An operation method of a first terminal in a communication system is provided. The method includes transmitting, to a base station, a configuration request message requesting configuration of a sidelink (SL) bandwidth part (BWP) used for sidelink communication between the first terminal and a second terminal. A configuration information message is received including configuration information of the SL BWP from the base station. The sidelink communication is performed with the second terminal using one or more SL BWPs indicated by the configuration information and in response to determining that reconfiguration of the one or more SL BWPs is necessary, a reconfiguration request message is transmitted to the base station.

The embodiments of the present disclosure provide a wireless communication method and device, which can implement normal operation of a terminal device having multiple capabilities. The method includes reporting, by a first terminal device, capability information of the first terminal device and capability information of a third terminal device to a network device; acquiring, by the first terminal device, a first transmission resource set configured by the network device for performing sidelink communication; and performing, by the first terminal device, the sidelink communication with the third terminal device using a resource in the first transmission resource set.

The disclosure relates to methods, devices, and systems for wireless communications. A wireless communications system may support unicast and broadcast communications for different radio access technologies (RATs). To support the coexistence of different RATs, a user equipment (UE) may report, to a base station, a UE capability message containing a band combination including one or more bands for a first RAT (for example, New Radio (NR)) and one or more bands for a second RAT (for example, Long Term Evolution (LTE)) and an indication of a baseband budget for the second RAT for the band combination. In some implementations, the UE may transmit a broadcast interest indicator to the base station requesting a broadcast service. The base station may configure the UE with a carrier aggregation (CA) configuration based on the UE capabilities, such as the band combination and corresponding baseband budget for the second RAT, and the interest indicator.

A communication system includes at least one terminal device for acquiring at least information about a battery; and at least one management device. The management device communicates with the terminal device. One of the management device and the terminal device includes a multi-band communication device configured to perform communication using plural, different frequency bands. The other of the management device and the terminal device includes a specific communication device configured to perform communication using at least one frequency band among the plural, different frequency bands.

Methods, systems, and devices for wireless communications are described. The method, system, or devices for wireless communications may implement receiving a grant for a first transmission scheduled for a first set of resources, the first transmission associated with a first transmission parameter; receiving an indication to cancel the first transmission; dropping the first transmission based on receiving the indication; determining a second transmission parameter for a second transmission based on the first transmission parameter and irrespective of dropping the first transmission; and performing or receiving the second transmission according to the second transmission parameter. Alternatively, a device may receive an indication to cancel the second transmission; drop the second transmission based on receiving the indication; and refraining from rescheduling the first transmission on the first set of resources based on receiving the indication and irrespective of dropping the second transmission.

A communication apparatus complying with an IEEE802.11 series standard, determines, based on information received from another communication apparatus connected to the communication apparatus, whether UL MU (Uplink Multiuser) communication of the other communication apparatus is enabled or disabled, acquires, from the other communication apparatus by a method according to a result of the determination, a BQR (Bandwidth Query Report) representing a state of a communication resource usable by the other communication apparatus, and decides the communication resource used to communicate with the other communication apparatus based on the acquired BQR.

To provide a low latency near RT RIC, some embodiments separate the RIC's functions into several different components that operate on different machines (e.g., execute on VMs or Pods) operating on the same host computer or different host computers. Some embodiments also provide high speed interfaces between these machines. Some or all of these interfaces operate in non-blocking, lockless manner in order to ensure that critical near RT RIC operations (e.g., datapath processes) are not delayed due to multiple requests causing one or more components to stall. In addition, each of these RIC components also has an internal architecture that is designed to operate in a non-blocking manner so that no one process of a component can block the operation of another process of the component. All of these low latency features allow the near RT RIC to serve as a high speed IO between the E2 nodes and the xApps.
