Abstract:
User equipments can achieve quick channel synchronization when establishing a connection to base stations transitioning from a sleep mode to an active mode by using discovery resource signal (DRS) processing results and cell reference signal (CRS) processing results to establish channel synchronization with a CRS antenna port. More specifically, the user equipment may be notified that the CRS antenna port and DRS antenna port are quasi-co-located (QCL), and then use DRS processing results in conjunction with CRS processing results to obtain faster channel synchronization with a CRS antenna port. This may be particularly beneficial when the target BS is transitioned from a sleep mode to an active mode in order to accept a handover of the user equipment.
