Method, equipment, device and system for sending device detection signal
摘要
說明書
randomly select the positions of the discovery resource elements for sending the device discovery signals;
determine the time positions and/or frequency positions of the discovery resource elements for sending the device discovery signals according to a user equipment identity; and
determine the time positions and/or frequency positions of the discovery resource elements for sending the device discovery signals according to the discovery resources indicated by the configuration information;
herein the positions of the discovery resource elements for sending the device discovery signals for the first time include:
resource positions when the discovery signals are sent for the first time during a process for sending the device discovery signals; and corresponding resource positions where the device discovery signals are sent in the first discovery resource period.
The central processing unit 74 is further arranged to generate an initial sequence of a pseudorandom sequence according to at least one of the following parameters: a user equipment identity, a physical cell identity and a discovery resource period identity;
generate the pseudorandom sequence according to the initial sequence and a pseudorandom sequence generation manner;
generate the positions of the discovery resource elements for sending the device discovery signals according to the pseudorandom sequence and at least one of the following parameters: an index of the discovery resource period and the number of the discovery resource elements in the discovery resource period; and
