Abstract: Various aspects described herein relate to techniques for synchronization channel design and signaling in wireless communications systems (e.g., a 5th Generation (5G) New Radio (NR) system). In an aspect, a method includes identifying a frequency band supported by a user equipment (UE), identifying one or more frequency locations based on the identified frequency band, and the one or more frequency locations are a subset of synchronization raster points used for synchronization signal transmission. The method further includes searching for at least one synchronization signal based on the one or more identified frequency locations.

Abstract: A configurable new radio (NR) resource scheduling and indication transmission procedure that may be executed by a base station and a user equipment (UE) is disclosed. For example, a base station may determine a number of synchronization signal blocks available for transmission of non-scheduling data, and transmit an indication signifying at least one of the number of synchronization signal blocks or a location of each of the number of synchronization signal blocks. Further, a UE may receiving an indication signifying at least one of a number of synchronization signal blocks or a location of each of the number of synchronization signal blocks. The UE may further determine one or more resource elements forming the number of synchronization signal blocks where non-scheduling data has been scheduled for transmission. The UE may receive the non-scheduling data within the one or more resource elements forming the number of synchronization signal blocks.

Abstract: Certain aspects of the present disclosure provide techniques for a slot format indicator (SFI) and slot aggregation level indication in a group common physical downlink control channel (GC PDCCH) and conflict handling for the SFI. According to certain aspects, a method of wireless communication by a base station (BS) is provided. The BS can determine a slot aggregation level and a format of the aggregated slots and send a downlink control channel including a SFI indicating the format of the aggregated slot and an indication of the slot aggregation level. The UE can receive the downlink control channel including the SFI and the indication of the slot aggregation level and the UE can determine a format of a current slot based on the received SFI and slot aggregation level.

Abstract: Aspects herein describe increasing density of reference signal transmissions in wireless communications. A plurality of reference signal configurations, each indicating resource elements for one or more antenna ports over which reference signals for the one or more antenna ports are scheduled for transmission, can be received. An association configuration indicating an association between at least two antenna ports as having similar channel characteristics can also be received. A plurality of reference signals can be received in the resource elements corresponding to the at least two antenna ports as indicated in the at least two of the plurality of reference signal configurations, which can be used to perform a channel measurement of the similar channel characteristics of channels of the at least two antenna ports over at least a portion of the plurality of reference signals.

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.
