    Abstract: An apparatus and system for power saving in a user equipment (UE) are described. The UE uses signal-to-interference-plus-noise (SINR) of radio link monitoring (REM) signals to determine whether to enter or exit a relaxation state in which the frequency of measurement of the REM signals is reduced, as is feedback to the base station. The REM relaxation state is dependent on the average SINR of the REM signals over a predetermined time window. Alternatively, the REM relaxation state is dependent on SINR thresholds that include an SINR fluctuation range using a SINR threshold for REM in-sync or derived from a Cumulative Distribution Function (CDF) curve of SINR using a predetermined maximum SINR fluctuation.

    Abstract: Methods, systems, and storage media for providing multi-cell, multi-point single user (SU) multiple input and multiple output (MIMO) operations are described. In embodiments, an apparatus may receive and process a first set of one or more independent data streams received in a downlink channel from a first transmission point. The apparatus may receive and process a second set of one or more independent data streams received in a downlink channel from a second transmission point. The apparatus may process control information received from the first transmission point or the second transmission point. The control information may include an indication of a quasi co-location assumption to be used for estimating channel characteristics for reception of the first set of one or more independent data streams or the second set of one or more independent data streams. Other embodiments may be described and/or claimed.

    Abstract: An apparatus and system of establishing a Transmission Configuration Indication (TCI) state switch delay are described. The TCI state switch delay for a reference signal (RS) on a component carrier (CC) in intra-band carrier aggregation (CA) is dependent on whether a TCI state indicated in the DCI is known based on a type of Quasi Co-Location (QCL) and whether a common TCI state ID is known on the CC. The delay is known for a delay of QCL-typeD RS on the CC or any other QCL-typeD RS in the CC set that contains the CC. The delay may be based on that of a single CC delay, with the slot where the new TCI state applies determined based on a carrier with a smallest subcarrier spacing (SCS) in the CC or the CC set.
