Abstract: A method of wireless communications at a user equipment (UE) includes receiving, from a serving cell associated with a wireless network, a radio resource management (RRM) mode indicator that indicates a set of one or more beams for which cell measurement and reporting is to be performed by the UE; performing at least one cell measurement on at least one synchronization signal (SS) block received from at least one neighboring cell; determining, based at least in part on the RRM mode indicator, whether to decode a physical broadcast channel (PBCH) received in each SS block of the at least one SS block; and transmitting a cell measurement report, the cell measurement report based at least in part on the at least one cell measurement, the cell measurement report selectively including at least one beam index based at least in part on whether the PBCH is decoded.

Abstract: Aspects of the disclosure relate to a coexistence of a first radio access technology (RAT), such as a fifth generation (5G) new radio (NR) technology with a second RAT, such as a narrow-band internet-of-things (NB-IOT) technology. In a first aspect, a 5G NR resource block size and an NB-IOT resource block size are defined, and a compatible alignment of an NB-IOT resource block and a 5G NR resource block is identified. An offset associated with the compatible alignment is then determined in which the offset is within a threshold offset and facilitates an identification of a valid NB-IOT resource block. In a second aspect, an offset associated with a compatible alignment of a 5G NR resource block and an NB-IOT resource block is ascertained, and a channel raster is shifted according to the offset associated with the compatible alignment.

Abstract: Methods and apparatus are described for decoder processing. The methods and apparatus determine decoding performance occurring in a decoder having first and second decoder components with a feedback component between the first and second decoder components. The feedback is selectively switching between feedback passing soft information between the first and second decoder components and feedback passing hard information between the first and second decoder components based on the determined decoding performance.

Abstract: The present disclosure presents a method and apparatus for improving demodulation reliability of an uplink (UL) high speed dedicated physical control channel (HS-DPCCH) at a base station. For example, the disclosure presents a method for receiving a secondary pilot channel from a user equipment (UE) on an uplink (UL) and demodulating the HS-DPCCH using at least the secondary pilot channel. As such, improved demodulation reliability of an uplink (UL) high speed dedicated physical control channel (HS-DPCCH) at a base station may be achieved.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may transmit feedback, such as hybrid automatic repeat request (HARD) feedback for groups of code blocks rather than for an entire transport block or individual code blocks. The wireless device may transmit an acknowledgement (ACK) or negative-acknowledgement (NACK) to provide feedback for each code block group of a set of code block groups. An ACK may indicate that code blocks in a code block group were successfully decoded, and a NACK may indicate that at least one code block in a code block group was not successfully decoded. Wireless devices may support several techniques for grouping code blocks for feedback reporting to allow for efficient retransmissions and limited overhead. Different grouping schemes may be employed depending on system constraints, device capability, link conditions, or the like.

Abstract: Aspects of the present disclosure provide methods and apparatus for selecting beamforming parameters for uplink transmissions based on an uplink reference signal. An example method generally includes identifying one or more parameters for beamformed transmission to a transmit receive point (TRP), transmitting a reference signal using beamforming in accordance with the identified parameters, and receiving, from the TRP in response to the reference signal, signaling for adjusting the one or more parameters for one or more subsequent beamformed transmissions.

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.
