    Abstract: Scalable 2D joint phase-time arrays (JPTA) support multiple simultaneous RF beams without sacrificing array gain. A 2D JPTA comprises M antenna groups that each comprise N antennas, each coupled to one of N phase shifters. The array comprises M delay elements configured to: apply a time delay to a first signal to be transmitted by one of the antenna groups while each phase shifter in the group phase shifts the time-delayed first signal and feeds the phase-shifted-and-time-delayed first signal to the corresponding antenna, or apply the time delay to a second signal received from the group while each phase shifter phase shifts a third signal received from the antenna, the second signal being a combination of the phase-shifted third signals. The time delays produce a beam spread in a first dimension of the array such that multiple beams are formed in different directions.

    Abstract: Methods and apparatuses for supporting multiple beam operations in wireless communication systems is provided. The method comprises: determining a configuration information (ID) of a user equipment (UE) based on indication information included in a synchronization signal and physical broadcast channel (PBCH) block (SSB), the configuration information corresponding to a first value or a second value; determining, based on the configuration information, an operation mode to identify a UE transmit (Tx) scheme and a UE receive (Rx) scheme, wherein the operation mode comprises a first operation mode corresponding to the first value or a second operation mode corresponding to the second value; and transmitting or receive signals based on the determined operation mode.

    Abstract: A base station includes a controller configured to configure an MRS resource set comprising a group of MRS resources, each MRS resource comprising a set of MRS antenna ports. If at least two MRS antenna ports belong to a same MRS resource, then the at least two MRS antenna ports are quasi co-located with respect to a first set of QCL parameters, else if the at least two MRS antenna ports belong to a same MRS resource set, then the at least two MRS antenna ports are quasi co-located with respect to a second set of QCL parameters, and else the at least two MRS antenna ports are not quasi co-located with respect to either the first set or the second set of QCL parameters. The MRS is a CSI-RS for estimating a CSI and at least one of the first set and the second set of QCL parameters.

    Abstract: A UE in a wireless communication system is provided. The UE comprises a transceiver configured to receive, from a BS, a SS/PBCH block including the PBCH using a first frequency location (GSCN-Current) over downlink channels, GSCN-Current being based on a set of predefined synchronization rasters that is determined by a global synchronization channel number (GSCN). The UE further comprises a processor operably connected to the transceiver, the processor configured to determine the SS/PBCH block, identify content of a PBCH included in the determined SS/PBCH block, determine a configuration for at least one of the SS/PBCH block that is associated with a PDCCH including scheduling information for RMSI on the GSCN-Current or the SS/PBCH block that is not associated with the PDCCH including the scheduling information for the RMSI on the GSCN-Current.
