Embodiments of the present disclosure provide a method for transmitting and receiving a service between a terminal device and a base station. The terminal device receives radio resource configuration information and indication information from the base station. The radio resource configuration information includes frequency band information of N (N≥2) frequency ranges and characteristic information of radio interface technologies corresponding to each of the N frequency ranges. The indication information indicates a frequency range in which a physical layer resource is to be used by the terminal device to transmit and receive the service. Characteristics of the radio interface technologies include at least one of: a cyclic prefix (CP) length, a duration of an orthogonal frequency division multiplexing (OFDM) symbol, or a subcarrier spacing.

A method for processing an I/O request and a computer system are provided. The method includes: receiving an I/O write request from a virtual machine; writing first data to be written as requested by the I/O write request into a local persistent storage area; determining a file type of a file to which the first data belongs; and writing the first data into a remote shared storage area if the file type of the file to which the first data belongs is a user file or a system file. Thus access traffic on the remote shared storage area can be reduced.

A dynamic mobile network architecture is provided, with the objective of meeting greenhouse gas emission targets. The network adapts over time based on time varied traffic demand/load. This is achieved by providing two layers of base stations (BS). The top layer contains super BS that have larger coverage areas than the base stations of the second layer. Depending on traffic conditions, base stations of the second layer can be switched into a reduced power mode. Signalling procedures are provided for setting up connections between the BS of the second layer and the super BS, and for switching off and then activating previously switched off second layer BS. In some cases, the BS of the second layer has a lower power listening receiver to allow itself to be activated while the BS is otherwise powered off.

This application provides example sidelink resource configuration methods and apparatuses. One example method includes receiving, by a first terminal, first configuration information of a sidelink resource, where the sidelink resource configured by using the first configuration information includes a common resource in resource pools or sidelink bandwidth part BWP resources of N terminals in a terminal group, the terminal group includes the first terminal, and N is a positive integer. The first terminal can then perform sidelink communication with a terminal in the terminal group on the sidelink resource.

The disclosure describes example methods. One example method includes obtaining sidelink transmit power and uplink transmit power, where the sidelink transmit power is transmit power of a sidelink in a first time unit, and the uplink transmit power is transmit power of an uplink in the first time unit. An actual transmit power of the sidelink in the first time unit based on the sidelink transmit power, the uplink transmit power, and maximum transmit power. The first time unit includes N first time subunits, M second time subunits in the N first time subunits overlap uplink resources, M is less than or equal to N. The N first time subunits are time subunits used for sidelink transmission in the first time unit, and the actual transmit power of the sidelink is constant in the N first time subunits.

Example quasi co-location information determining methods and apparatus are described. One example method includes determining a quantity X of pieces of quasi co-location QCL information, where X is a positive integer. When it is determined that the quantity X of pieces of QCL information is two, and that DCI corresponding to a current data channel does not indicate QCL information of an antenna port of the data channel, or that an interval between the current data channel and the DCI corresponding to the data channel is less than a threshold, two pieces of default QCL information of the antenna port of the data channel are determined.
