Abstract: Aspects of the present disclosure provide methods and apparatuses that can utilize different subframe structures to estimate a channel during wireless communication in different scenarios. When a scheduling entity determines that a scheduled entity is near or at a cell edge, the scheduled entity may use a special subframe to estimate the channel utilizing more resources of the subframe, for example data signals. The special subframe can facilitate channel estimation by using a less complex (or lower rank) modulation and coding scheme (MCS) for the data symbols than a normal subframe for other scheduled entities not located near the cell edge.

Abstract: Aspects of the present disclosure provide for enhanced channel estimation in a wireless communication network. Uplink channel estimation may be enhanced by increasing the uplink transmit power of an uplink reference signal. For example, the uplink transmit power may be increased by multiplying a measured downlink path loss by a predetermined factor to produce an increased downlink path loss and calculating the uplink transmit power based on the increased downlink path loss. Downlink channel estimation may be enhanced by increasing a number of tones on a downlink reference signal assigned to a scheduled entity relative to the number of tones assigned to other scheduled entities.

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, systems, and devices for wireless communication are described. One method includes identifying a plurality of intermediate precoders corresponding to a plurality of tone subsets. The plurality of intermediate precoders define a plurality of vectors across the plurality of tone subsets. The method further includes selecting, for each vector of the plurality of vectors, a subset of non-frequency domain components of the vector, such as time-domain components; modifying the plurality of intermediate precoders to a plurality of smoothed precoders based at least in part on the selected subset of non-frequency domain components for each vector; and precoding a plurality of transmit streams using the plurality of smoothed precoders. The plurality of smoothed precoders is smoothed in a frequency domain compared to the plurality of intermediate precoders. Smoothing precoders may enable application of wideband channel estimation techniques using user equipment (UE)-specific reference signals.

Abstract: Aspects relate to measuring downlink beam quality in the presence of self-interference when operating in a full duplex mode configured for concurrent transmission and reception within an overlapping bandwidth. A user equipment (UE) may communicate with a base station over one or more of a plurality of uplink beams and downlink beams. For each uplink beam, the UE may obtain beam quality measurements associated with each of the downlink beams to identify a set of usable downlink beams. The UE may further transmit a report to the base station indicating the set of usable downlink beams for at least one uplink beam.

Abstract: Generally, the described techniques provide for duplex mode configuration for control information (e.g., duplex mode configuration for communication of downlink control information). For example, duplex modes may be defined (e.g., as full duplex (FD) capable, FD only, half duplex (HD) only, etc.), and such duplex modes may be configured for control resource sets (CORESETs), search space (SS) sets, or both. In some examples, duplex modes configured for a CORESET/SS set may depend on the priority of information conveyed via the CORESET/SS set. For example, a CORESET/SS set for high priority or critical control information may be configured with a HD mode to avoid FD self-interference, while CORESET/SS set for other control information may be configured with a FD mode to improve spectrum efficiency. Techniques for resolving conflicting duplex mode configurations (e.g., when a HD mode is configured for a SS set within a CORESET configured with FD) are also described.
