Abstract:
The present invention provides a method for updating a system message, where an eNB performs a communication resource negotiation with a neighboring eNB to obtain an available subframe, sends a paging message including a system message update indication to a UE, wherein the system message update indication indicates that the system message is updated, and sends a system message update indication message to the UE in the available subframe, wherein the system message update indication message is used to update the system message. The present invention further provides a communication system and an eNB. By using the method for updating a system message, the communication system, and the eNB according to the present invention, a message is transmitted in a low-interference available subframe, thereby reducing adverse effects caused by interference and improving accuracy of system message update.

Abstract:
A communication method and a wireless communications apparatus are provided. The method includes sending, by the wireless communications apparatus, a first request message to a first cell, where the first request message is used to request to release a wireless connection between a first user and the first cell, receiving, by the wireless communications apparatus, a response message from the first cell, where the response message is used to respond to the first request message, and sending, by the wireless communications apparatus, a second request message to a second cell, where the second request message is used to request to establish a wireless connection between a second user and the second cell.
Abstract:
This application provides a communication method and apparatus. The method may be applied to a small data transmission procedure. The method includes: A terminal device receives first indication information from a network device, where the first indication information indicates timing advance information. The terminal device performs the following operations based on a running state of at least one of a first time alignment timer and a second time alignment timer: applying the first indication information or ignoring the first indication information.
Abstract:
This application provides a communication method and apparatus to improve communication performance of a novel terminal device. The method includes: receiving a first message from a source access network device, and determining a capability of a first cell based on the first message, where the first message indicates to hand over a first terminal device to the first cell, the first cell corresponds to a target access network device, and the capability of the first cell is whether the first cell supports serving a terminal device with a reduced capability; and determining, based on the capability of the first cell, whether to access the first cell.
Abstract:
A communication processing method, a communication processing apparatus, and a system, to improve resource utilization. A first terminal device generates first information. The first terminal device sends the first information to a network device, where the first information is used to indicate any one or more of the following content: information indicating that the first terminal device releases a first resource; the first resource released by the first terminal device; and information indicating that the first terminal device requests a second resource from the network device.
Abstract:
A communication method includes: when a network device meets an enabling condition, sending, by the network device, configuration information to a terminal, where the configuration information includes at least one of a type of indication information, a form of the indication information, or a receiving location of the indication information; and sending the indication information to the terminal, where the indication information is used to indicate the terminal whether to monitor a physical downlink control channel PDCCH, or indicate the terminal to monitor a PDCCH, or indicate the terminal not to monitor a PDCCH; or the indication information is used to indicate the terminal whether to receive a physical downlink shared channel PDSCH, or indicate the terminal to receive a PDSCH, or indicate the terminal not to receive a PDSCH. This improves flexibility of using the indication information (for example, a UPSS) by the terminal.
Abstract:
Embodiments of this application provide a discontinuous reception control method, the method is as follows: receiving first control information transmitted in a unicast manner, where the first control information is for scheduling first data transmitted in a multicast manner; and performing, by a communication apparatus, any one or more of the following actions: starting or restarting a first timer, where the first timer indicates duration after newly transmitted control information or newly transmitted data is scheduled; stopping a second timer, or starting or restarting a second timer, where the second timer indicates duration in which the communication apparatus receives retransmitted data; and starting or restarting a third timer, where the third timer indicates waiting duration before the communication apparatus receives the retransmitted data, where the timers are timers corresponding to DRX associated with multicast.
Abstract:
A method includes: performing, by a terminal device, data transmission based on a configuration parameter of a currently activated first bandwidth part BWP, where the configuration parameter of the first BWP includes at least one of a first resource offset, a first bandwidth, and a first subcarrier spacing; determining, by the terminal device, a first random access resource and a second configuration parameter for random access, where the second configuration parameter includes at least one of a second resource offset, a second bandwidth, and a second subcarrier spacing; sending, by the terminal device, a random access request to the network device on the first random access resource; and receiving, by the terminal device, a random access response based on the second configuration parameter, where the random access response is sent by the network device based on the random access request.
