Abstract:
The present invention discloses a channel selection method and device and relates to the communications field, so as to resolve a problem of applying an unlicensed spectrum to a wireless cellular network. The channel selection device is configured to acquire a candidate unlicensed channel, determine an available unlicensed channel from the candidate unlicensed channel, where the available unlicensed channel is an unlicensed channel that is not interfered or on which a strength of an interference signal is less than an interference detection threshold, and acquire a first operation channel from the available unlicensed channel, where the first operation channel is a channel on which the channel selection device performs communication with user equipment in a wireless cellular network mode.
Abstract:
Embodiments of the present invention provide a service processing method for a new carrier type cell, an apparatus, and a communications system. The method includes: receiving, by user equipment UE, a system message sent by a base station corresponding to a legacy carrier type LCT cell, where the system message includes multimedia broadcast multicast service MBMS configuration information of a new carrier type NCT cell; and performing, by the UE, service configuration processing on an MBMS of the NCT cell according to the MBMS configuration information of the NCT cell.
Abstract:
The present invention provides a method for processing a heartbeat message, a method for acquiring a heartbeat period, and an access network device. The method for processing a heartbeat message includes: acquiring, by a terminal, heartbeat control information (101); and sending, by the terminal, a heartbeat message according to the heartbeat control information (102). Embodiments of the present invention can reduce the signaling processing burden on a network side device and reduce the power consumption of a terminal, thereby ensuring the normal operation of the communication service of the terminal.
Abstract:
A terminal device obtains first configuration information, where the first configuration information includes indication information of a UL MAC CE. Then, the terminal device preferentially sends a UL MAC PDU or an SL MAC PDU based on the indication information, where the UL MAC PDU can be used to transmit the UL MAC CE.
Abstract:
A time domain resource format configuration method is provided. In addition to configuring time domain resources for an integrated access and backhaul (IAB) node based on a downlink-flexible-uplink time domain resource format, an IAB donor may further configure time domain resources for the IAB node based on an uplink-flexible-downlink time domain resource format, so that the time domain resources can be flexibly configured for the IAB node, to improve utilization and a throughput of the time domain resources in an IAB network.
Abstract:
A communication method and apparatus are provided. The method includes: An IAB donor gNodeB determines first indication information, and then sends a first message to an eNB, where the first message includes a first control plane message and the first indication message; and the eNB may determine a first radio bearer based on the first indication information in the received first message, and then sends a second message including the first control plane message to an IAB node by using the first radio bearer. The first radio bearer corresponds to a type of a downlink F1AP message, so that the eNB selects different radio bearers for different types of downlink F1AP messages, thereby providing an effective QoS guarantee for a service of a terminal.
Abstract:
This application provides example relay communications methods and apparatuses. A first terminal device can receive, from a second terminal device, indication information used to indicate the second terminal device to stop providing a first relay service between the first terminal device and a radio access network device. The first terminal device can then send notification information to the radio access network device through a third terminal device, to notify the radio access network device that the first terminal device accesses the radio access network device by using a second relay service of the third terminal device.
Abstract:
This application provides a method of determining an association between logical channel groups, including: The first backhaul node receives a first buffer status report from a first device, where the first buffer status report is used to determine uplink buffer statuses of one or more first logical channel groups of a MAC entity corresponding to the first backhaul node and the first device. The first backhaul node determines, based on the first logical channel group(s) and a first mapping relationship, one or more second logical channel groups associated with the first logical channel group(s), where a second device is a parent node of the first backhaul node, and the first mapping relationship includes a mapping relationship between the first logical channel group(s) and the second logical channel group(s) of a MAC entity corresponding to the first backhaul node and the second device.
Abstract:
This application discloses a communication method, a communications apparatus and a communications system, to resolve a problem that a terminal cannot quickly resume a communication connection to a secondary node. The method includes: sending a first message to a first master node to request state transition of a terminal from a third mode to a connected mode; receiving a second message from the first master node, where the second message comprises a first security parameter and SCG configuration information, and completing, based on the first security parameter and the SCG configuration information, a communication connection to the secondary node.
Abstract:
A first terminal receives first sidelink SL carrier configuration information from a second terminal, the first SL carrier configuration information includes first bandwidth part BWP configuration information, and the first BWP configuration information includes one or more first resource pools; the first terminal performs unicast connection communication with the second terminal based on the first BWP configuration information.
