Abstract: Split synchronization signal configuration for unified synchronization channels and techniques for indicating communication block boundaries in wireless communication systems that use a unified synchronization signal configuration that may be used in different communication modes are described. The disclosed split synchronization signal configuration allows the same synchronization signal configuration to be used in different communication modes (or numerologies) that operate on different frequencies. The boundary indication techniques of embodiments allow efficient indication of the beginning of a communication block (such as a frame, subframe, or slot) relative to the beginning of a unified synchronization signal configuration.

Abstract: Wireless communications systems and methods related to multi-slot slot format indicators (SFIs) are provided. In one embodiment, a first wireless communication device communicates, with a second wireless communication device, a first SFI for a first set of slots and a second SFI for a second set of slots overlapping with the first set of slots. The first wireless communication device communicates with the second wireless communication device based on at least one of the first SFI or the second SFI. In one embodiment, a first wireless communication device communicates, with a second wireless communication device, a configuration for a first slot and an SFI indicating slot formats for a set of slots including the first slot. The SFI indicates an unspecified slot format for the first slot. The first wireless communication device communicates with the second wireless communication device in the first slot based on the configuration.

Abstract: Techniques and devices for signaling control and system information are provided. In one aspect, a base station determines a type of multiplexing and a periodicity for transmission of remaining minimum system information (RMSI). The type of multiplexing is for multiplexing the RMSI with a synchronization signal (SS) block. The base station generates an indicator that signals the type of multiplexing and the periodicity. In another aspect, a user equipment (UE) identifies the indicator and determines the type of multiplexing and the periodicity based on the indicator. The UE processes the transmission of RMSI based on the type of multiplexing and the periodicity. Other aspects and features are also claimed and described.

Abstract: Power control in new radio (NR)-to-NR dual connectivity communications is disclosed. A UE, compatible for NR-to-NR dual connectivity, may receive a transmit power configuration and a power allocation configuration. The transmit power configuration identifies the designated reserved power for each of the cell groups participating in the dual connectivity communication. The power allocation configuration identifies to the UE whether to operate access to excess transmission power by either mode 1 rules, which may introduce phase discontinuity into ongoing transmissions, or mode 2 rules, which use a look-ahead functionality to trigger joint determination and allocation of transmission power among known uplink transmissions over a given transmission duration. After the determined transmission power allocation has been made, the UE transmits the dual connectivity transmissions according to the determined power.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first cell associated with a first radio access technology (RAT) and a first radio frequency spectrum band that conflicts with a second slot format configuration for a second cell associated with a second RAT and a second radio frequency spectrum band during at least a portion of a transmission time interval (TTI). The UE may determine that the first cell has a priority over the second cell, based on the configured slot formats or based on the radio frequency bands, and may drop a communication on the second cell based on the identified priority. The UE may then communicate during at least a portion of the TTI on the first cell while the UE drops a communication on the second cell.

Abstract: Systems, methods, and devices for secondary cell activation using temporary reference signals and beam selection are provided. In one aspect, a method of wireless communication is performed by a UE and includes receiving, from a base station (BS) via a first cell, an activation command to activate a second cell different from the first cell. The method further includes receiving, from the BS via the second cell during a cell activation period, a first reference signal different from a synchronization signal block (SSB) based on beam information. The method further includes performing a first measurement of the first reference signal, and operating in the second cell based on the first measurement.

Abstract: Certain aspects of the present disclosure provide techniques and apparats relating to designs for the remaining minimum system information (RMSI) control resource set (CORESET) and the other system information (OSI) CORESET. In certain aspects, a wireless communication device (e.g., user equipment) is enabled to determine the location of Type0-PDCCH common search space CORESET and the OSI CORESET in the frequency and time domains based on the location of the synchronization signal block (SSB) transmissions in the frequency and time domains. Determining the location of the RMSI CORESET and the OSI CORESET frequency and time resources enables the UE to receive the RMSI CORESET and the OSI CORESET, respectively.

Abstract: Techniques are described herein for mobility procedures configured to maintain connectivity with a device, such as a user equipment (UE), when the UE moves between single-frequency network (SFN) areas. When the UE operates in a radio resource control (RRC) inactive state or an RRC idle state, the UE may utilize hierarchical mobility. As the UE moves throughout the coverage area of the network, the UE may use mobility procedures for moving between a serving radio access network (RAN) notification area (RNA) and a neighboring RNA (e.g., inter-RNA procedures), and/or procedures for moving between SFN areas within the serving RNA (e.g., intra-RNA procedures), which may include procedures for moving between tracking areas (TAs). In some mobility procedures, the UE may skip decoding a system information block. In some mobility procedures, the UE may skip reading the system information. An SFN area may be a radio access network area code (RAN-AC).
