Transmission method for PMCH resources, base station and user terminal

Abstract

A method, base station, and user terminal for physical multicast channel resource transmission, related to the field of mobile radio communication. The disclosed method of the present invention comprises: the base station transmits corresponding data on the basis of a subframe type and / or a service cell type, where the subframe type comprises a multicast-broadcast single-frequency network (MBSFN) and a non-MBSFN, the service cell type comprises a service cell having cell-specific reference signal (CRS) transmission and a service cell having no CRS transmission, and the data comprises unicast service data and / or multicast service data. Also disclosed are the base station and the user terminal. When employed, the technical solution of the present application allows intra-subframe frequency-division multiplexing of a unicast service and of a PMCH to be of increased rationality, and allows a receiving end access system of the unicast service and operations in the system to be subjected to minimized impact from the PMCH.

Description

technical field

[0001] The invention relates to the field of mobile wireless communication, in particular to physical multicast channel (PMCH) resource allocation and use. Background technique

[0002] In LTE R11, a new carrier type was discussed, but in the LTE R11 stage, the standardization of the new carrier has not been completed. At present, it has entered the LTE R12 stage, and the standardization of the new carrier has been postponed to LTE R12, and there are Some preliminary conclusions are drawn and some new functions are introduced.

[0003] The new carrier is being standardized as a new carrier type. The following are some consensus conclusions in the new carrier:

[0004] In the new carrier, a single-port cell-specific pilot (CRS) with a period of 5 milliseconds (5ms) is used to perform synchronous tracking (in the text, it is called 5msCRS, or called synchronous tracking CRS), which is obviously different from the CRS in the existing system. The same, but the ...
