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.

Abstract: A next-generation base station can update an uplink-downlink (UL/DL) configuration of a cell more frequently than legacy user equipments (UEs) are configured to recognize UL/DL updates while preventing non-compliant uplink transmissions in downlink subframes. For instance, a next-generation base station can restrict updates to the uplink-downlink configuration such that uplink timeslots previously allocated for random access channel (RACH) transmission opportunities by legacy UEs remain configured for uplink transmission. Alternatively, the next-generation base station can restrict the allocation of RACH transmission opportunities of legacy UEs to timeslots that are statically configured for uplink transmission. Notably, such a restriction may be selectively applied to legacy UEs, so as to not limit the performance of next-generation UEs.

Abstract: A network controller may configure one or more channel state information-reference signal (CSI-RS) configurations for transmitting RSs to user equipments (UEs) for tracking. A CSI-RS configuration may specify a set of CSI-RS resources for transmitting RSs in two consecutive slots. The set of CSI-RS resources may include a plurality of one-port CSI-RS resources configured according to the CSI-RS configuration. The CSI-RS configuration may specify a quasi co-location (QCL) configuration including a set of QCL parameters, where a demodulation reference signal (DMRS) has a QCL relationship with the RS with respect to the set of QCL parameters. The network controller may signal the one or more CSI-RS configurations to UEs.
