Abstract: Aspects of the present disclosure provide various synchronization signal (SS) block designs that can facilitate channel estimation and demodulation in 5G New Radio (NR) networks. An exemplary SS block includes a set of time-frequency resources that are allocated to carry a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS) and a Physical Broadcast Channel (PBCH) that are time and/or frequency multiplexed within the SS block. In some examples, unused time-frequency resources of the SS block may be used or allocated for supplemental channels that can improve and/or extend wireless link coverage.

Abstract: Methods, systems, and devices for wireless communication are described. A discontinuous reception (DRX) periodicity may be configured to enable monitoring of a reference signal (RS) for RLM procedures. For example, a transmitting device may configure a DRX periodicity for an RS, where the configured DRX periodicity may include a periodicity of discrete transmissions of the RS or a periodicity of a transmission window in which the RS is located. Accordingly, a receiving device may identify the DRX periodicity and monitor radio link quality using the RS based on the DRX periodicity. In some examples, the RS may be transmitted independent of control channel transmissions, and the transmitting device may configure one or more control resource sets for the RS.

Abstract: Aspects of the present disclosure describe determining an uplink channel raster for determining frequency location of an uplink channel over which to transmit uplink communications to a base station. Uplink communications can be transmitted to the base station over the uplink channel. The uplink channel raster can be shifted, in frequency, with respect to a legacy uplink channel raster of a legacy communication technology to facilitate coexistence, in an uplink carrier, of the uplink channel and one or more uplink channels of the legacy communication technology.

Abstract: Wireless communication devices are adapted to facilitate a random access procedure. According to one example, scheduled entity can transmit a first transmission that is received by a scheduling entity. The first transmission may include a physical random access channel (PRACH) preamble sequence and a first message including information for determining a device-specific network identifier for the scheduled entity. The scheduling entity may transmit a second transmission that is received by the scheduled entity. The second transmission may include information on a physical downlink control channel (PDCCH) addressed to the device-specific network identifier for the scheduled entity, and a second message on a physical downlink shared channel (PDSCH). Other aspects, embodiments, and features are also included.

Abstract: Techniques for structured channel rasters for unlicensed spectrum are described. In an aspect, a first channel raster is identified, where the first channel raster is determined from a set of carrier frequencies and is used over an unlicensed or shared spectrum for a wireless wide area network (WWAN). The first channel raster is aligned with a second channel raster that is used over the unlicensed spectrum for a wireless local area network (WLAN). A frequency scanning may be performed by a user equipment (UE) or a network entity over the unlicensed spectrum for the WWAN using the first channel raster. In an aspect, the first channel raster is used over the unlicensed spectrum for the WWAN supported by the user equipment (UE) or the network entity.

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 or reading the system information. An SFN area may be a radio access network area code (RAN-AC).

Abstract: In aspects, a base station and a user equipment (UE) exchange synchronization signal blocks (SSBs) carrying a SFN identity, and a waveform of the SSBs has a secondary synchronization signal (SSS) symbol preceding a primary SS symbol. In aspects, a base station transmits a radio access network area code (RAN-AC) SS and RAN-AC page are quasi co-located (QCL). In aspects, a base station transmits a RAN-AC SS over a SFN while avoiding overlap of RAN-AC SS resources with channels employed for initial access of update area cells. In aspects, a base station provides a control resource set (CORESET) to a UE upon release from a connected state, and the UE receives a RAN-AC paging PDCCH based on the CORESET. In aspects, a base station transmits a SFN wake up signal (WUS) when there is a grant for paging, and the UE monitors for the WUS.
