20150078328 | METHOD AND DEVICE FOR TRANSMITTING REFERENCE SIGNAL SEQUENCE - The present invention provides a method and device for transmitting a reference signal sequence. The method includes: determining a position of an eCCE or an eREG mapped to an ePDCCH in a resource block pair; determining, according to corresponding relationship between the position of the eCCE or the eREG in the resource block pair and the antenna port of the reference signal; and transmitting a reference sequence over the antenna port of the reference signal, herein, the corresponding relationship between the position of the eCCE or the eREG in the resource block pair and the antenna port of the reference signal includes that the positions of at least two eCCEs or at least two eREGs correspond to one of the antenna ports of the reference signal. | 03-19-2015 |
20150195814 | BROADCAST MESSAGE TRANSMISSION METHOD, BASE STATION AND USER EQUIPMENT - The present invention provides a broadcast message transmission method, a base station and user equipment. The method includes: determining a resource position of a broadcast channel, wherein the broadcast channel occupies M physical resource blocks (PRBs) among m PRBs of a frequency band center of a carrier, m and M are positive integers, M is not greater than m, and m is not greater than the number of the PRBs corresponding to the system bandwidth; mapping the broadcast channel on the resource position; and sending a broadcast message through the broadcast channel. In the embodiments of the present invention, since the broadcast channel occupies M PRBs among m PRBs of a frequency band center of a carrier, by mapping the broadcast channel on the resource position and sending a broadcast message through the broadcast channel, the resource utilization rate of the carrier may be improved. | 07-09-2015 |
