Abstract: Disclosed are a data transmission method and apparatus. In embodiments of this application, a virtual cell comprising multiple cells can be configured, and data transmission can be implemented by time-division multiplexing among the cells, so that transmission carriers for a terminal service can be flexibly adjusted. Particularly, under the condition that transmission is deployed on an unlicensed spectrum resource, multiple cells operating on an unlicensed frequency band are aggregated into one virtual cell, and data transmission is implemented by time-division multiplexing among the cells; therefore, the interference in different frequency domains can be reduced and the system transmission efficiency can be improved.

Abstract: Disclosed are a method and device for performing MDT measurement configuration. The method includes: after receiving a notification of a change of subscription information about a user equipment, an MME storing a PLMN list for the user equipment to perform MDT measurement carried in the notification; and after receiving a notification for activating MDT measurement of the user equipment, the MME sending a trace start message to a serving base station of the user equipment, wherein the trace start message carries the PLMN list for the user equipment to perform MDT measurement.

Abstract: A method and an apparatus for transmitting a multicast service and a method and an apparatus for receiving a multicast service are provided. The method for receiving a multicast service includes receiving information about the multicast service transmitted by a network side on carriers, the carriers being an anchor carrier and/or non-anchor carriers; selecting a target carrier from the carriers according to the information about the multicast service, wherein the target carrier is the anchor carrier or the non-anchor carrier.

Abstract: Disclosed are a DRB mapping method and apparatus. The method in the embodiments of the present invention comprises: a network device and a terminal determining a DRB mapping manner, wherein the DRB mapping manner refers to whether a DRB is allowed to be mapped onto a licensed frequency band carrier and/or is allowed to be mapped onto an unlicensed frequency band carrier; and the network device and the terminal sending service data of the DRB on a designated carrier according to the determined DRB mapping manner. The embodiments of the present invention enable service data having certain requirements for the service quality (such as a VOIP service, or an online video game, etc.) not to be sent on an unlicensed frequency band carrier, thereby avoiding a service delay increase caused by the discontinuous work of the unlicensed frequency band carrier and a service quality reduction caused by time delay shaking, such that the service experience of a user can be effectively improved.
