Embodiments of the present disclosure disclose a service processing method, a PCRF, and a system. The method performed by the PCRF includes: obtaining service information of a service, where the service information includes a service identity; obtaining, according to user information and the service information, information indicating that the service requires QoS guarantee, and service chain information; when determining, according to the service chain information, that a network resource occupied by the service may be changed, sending the service identity and the information indicating that the service requires the QoS guarantee to a value-added service processor; receiving target service information, returned by the value-added service processor, of the service corresponding to the service identity; generating a first control policy according to the target service information; and sending the first control policy to a PCEF, so that the PCEF reserves a first network resource according to the first control policy.

Apparatuses and methods in a communication system are provided. A method comprises receiving from network instructions of how to control multi-user multiple input multiple output connections maintained by one or more radio access nodes, the connections utilising one or more slices. One or more radio access nodes perform, based at least in part on the received network instructions, multi-user pairing of terminal devices of the same or different slices, and determine, based at least in part on the received network instructions, slice-based quota taking multi-user pairing and interference arising from paired allocations into account.

A wireless device receives one or more first radio resource control (RRC) messages comprising configuration parameters indicating: a first sensing window of a first sensing procedure; and a second sensing window of a second sensing procedure. The wireless device selects, based on the first sensing window, a first candidate resource set for one or more sidelink transmissions. The wireless device selects, based on the second sensing window and for the one or more sidelink transmissions, a second candidate resource set from the first selected candidate resource set. The wireless device transmit the one or more sidelink transmissions via one or more resources of the second candidate resource set.

A method for operating a communication network includes: receiving, by a business support system of a resource reservation system, a reservation request, the reservation request indicating a Quality of Service (QoS) for an upcoming connection to be provided at a time distance from a reservation by the communication network for a terminal device and an application or service accessed by the terminal device via the upcoming connection; checking, by a bookkeeper decision engine of the resource reservation system, whether the business support system has availability for the indicated QoS; in response to confirming the availability for the indicated QoS, sending, by the bookkeeper decision engine, a reservation confirmation; and providing, by the communication network, the upcoming connection with the indicated QoS assigned for the terminal device at the time distance from the reservation.

An electronic device discussed herein may include radio frequency communication circuitry for communication on a radio frequency network according to a communication configuration, a processor, and memory. The memory may store instructions that, when executed by the processor, cause the electronic device to perform operations including receiving, a first muting configuration indicating when the radio frequency communication circuitry is to communicate using a first type of communication on a first frequency band and when the radio frequency communication circuitry is to communicate using a second type of communication on a second frequency band, where the first frequency band may overlap with the second frequency band. The memory may store instructions that, when executed by the processor, cause the electronic device to perform operations including transmitting or receiving a data packet using the radio frequency communication circuitry according to the communication configuration.

A method may comprise transmitting using a first uplink carrier and receiving a signal using a first downlink carrier. The signal may include a message indicating activation of a second uplink carrier. A method may further comprise initiating, based on the message, a timer associated with deactivation of the second uplink carrier. The method may further comprise transmitting using the second uplink carrier activated based on the message and deactivating the second uplink carrier on a condition that expiration of the timer is detected.
