Abstract
Provided are a system message transmission method and device, which relate to the field of wireless communications. According to the system message transmission method, a system message is transmitted at a preset resource location; and a physical downlink channel is transmitted according to the system message. The system message may include at least one of: frequency domain location information of a system, configuration information of a physical shared channel carrying a system message, configuration information of terminal access, available resource information of the physical downlink channel, and radio frame information.
Claims16
A system message transmission method, comprising:
- transmitting a physical shared channel carrying a system message, wherein the system message comprises available resource information of a physical downlink channel, wherein the available resource information of the physical downlink channel comprises:
- information of one or more unavailable resource elements of the physical downlink channel in a subframe;
- wherein the method further comprises:
- indicating the information of the one or more unavailable resource elements via a Cell-specific Reference Signal (CRS) port location;
- wherein the indication via the CRS port location is determined by any one of:
- a number of ports;
- a virtual cell identity;
- a number of ports and a virtual cell identity.
A system message transmission device, comprising:
- a system module, configured to transmit a physical shared channel carrying a system message, wherein the system message comprises available resource information of a physical downlink channel, wherein the available resource information of the physical downlink channel comprises:
- information of one or more unavailable resource elements of the physical downlink channel in a subframe;
- wherein the device further comprises:
- an indication module, configured to indicate the information of the one or more unavailable resource elements via a Cell-specific Reference Signal (CRS) port location;
