Abstract
Embodiments of the present invention provide a downlink information transmission method, a base station, and user equipment. The method includes: sending, by a first base station, downlink information by using a first period according to a first pattern; sending, by the first base station, the downlink information by using a second period according to the first pattern, or by using the first period according to a second pattern, or by using a second period according to a second pattern when the first base station determines to change a transmission period and/or a transmission pattern of the downlink information, where the second period is less than the first period, and OFDM symbols occupied by the second pattern are more than OFDM symbols occupied by the first pattern. The present invention is applicable to the field of communications technologies.

Claim
1. A downlink information transmission method, wherein the method comprises:
receiving, by user equipment, a instruction message, wherein the instruction message carries at least one of a transmission period or a transmission pattern for transmitting a synchronization signal by a first bases station; determining, by the user equipment, the transmission period and the transmission pattern for transmitting the synchronization signal by the first bases station according to the instruction message; and receiving, by the use equipment, the synchronization signal by using the determined transmission period and the determined transmission pattern from the first base station.
2. The method according to claim 1, wherein, before the receiving the instruction message, the method further comprises:
receiving, by the use equipment, the synchronization signal by using a preset transmission period and a preset transmission pattern from the first base station.
3. The method according to claim 1, wherein the determining, by the user equipment, the transmission period and the transmission pattern for transmitting the synchronization signal by the first bases station according to the instruction message comprises:
if the instruction message carries the transmission period and but does not carry the transmission pattern, determining, by the user equipment, the transmission period carried in the instruction message and a preset transmission pattern are the transmission period and the transmission pattern for transmitting the synchronization signal by the first bases station respectively.
4. The method according to claim 1, wherein the determining, by the user equipment, the transmission period and the transmission pattern for transmitting the synchronization signal by the first bases station according to the instruction message comprises:
if the instruction message carries the transmission pattern and but does not carry the transmission period, determining, by the user equipment, a preset transmission period and the transmission pattern which is carried in the instruction message are the transmission period and the transmission pattern for transmitting the synchronization signal by the first bases station respectively.
5. The method according to claim 1, wherein the determining, by the user equipment, the transmission period and the transmission pattern for transmitting the synchronization signal by the first bases station according to the instruction message comprises:
