Abstract: Methods, systems, and devices for wireless communications are described in which beamforming may be configured at a user equipment (UE) for narrowband communications. The UE may be a narrowband UE that may provide an indication to a base station that the UE is capable of performing beamforming communication for a unicast channel transmission. Such an indication may be provided in response to the UE receiving a non-beamformed broadcast channel transmission from the base station via a first carrier. The base station may receive the indication and configure the UE with a beamformed narrowband communications scheme. Such a beamformed formed narrowband communications scheme may be used for narrowband downlink shared channel communications, narrowband downlink control channel communications, or combinations thereof. In some cases, beamformed communications may be configured on a different carrier than the first carrier. The base station and UE may then communicate using beamformed transmissions.

Abstract: A method of providing positioning state information in a channel usable for conveying the positioning state information includes: obtaining a positioning state information resource allocation parameter; determining a positioning resource amount based on the positioning state information resource allocation parameter, the positioning resource amount being an amount of resources of the channel usable for conveying the positioning state information; and transmitting the positioning state information over the channel while occupying no more than the positioning resource amount of resources of the channel.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) performs at least one positioning measurement of at least one downlink positioning reference signal (DL-PRS) received from a transmission-reception point (TRP) during a positioning session, reports, to a positioning entity, a value of the at least one positioning measurement via low layer signaling, and determines a timestamp for the at least one positioning measurement relative to a reference point, wherein the timestamp comprises an amount of time between the reference point and a time at which the at least one positioning measurement is valid.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) performs at least one positioning procedure with at least one transmission-reception point (TRP), and transmits a positioning report for the at least one positioning procedure via first low layer signaling or both the first low layer signaling and second signaling different than the first low layer signaling.

Abstract: Certain aspects of the present disclosure propose methods for improving phase continuity in an uplink transmit time interval (TTI) bundle. A first method may include identifying a segment of UL subframes in the TTI bundle and maintaining substantially the same transmit power/timing/frequency when transmitting data to a node over the segment of UL subframes in the TTI bundle. Another method may include ignoring reception of downlink subframes for a duration of the TTI bundle.

Abstract: Certain aspects of the present disclosure provide techniques for identifying, from a resource pool allocated for sidelink communications between UEs, a first number of resources for transmissions from the first UE to a second UE based on a set of one or more parameters shared between the first UE and the second UE and identifying, from the resource pool, a second number of resources for transmissions from the second UE to the first UE based on the shared set of one or more parameters. The first UE may communicate with the second UE using the first and the second number of resources and avoid using the remaining available resources for power saving. For example, the first UE and the second UE may avoid sidelink communications on time slots on which no subchannels belong to either the first subset or second number of the resources.

Abstract: Aspects described herein relate to encoding uplink communications based on a coding table including determining to avoid certain portions of a coding table that may result decoding errors, or using a modified coding table, to improve decoding results. In one aspect, a network can transmit, to a device, a configuration indicating whether to use a modified coding table for encoding uplink communications.

Abstract: Certain aspects of the present disclosure provide techniques for a channel state information (CSI) report configuration for a multiple transmission reception point (TRP) transmission, such as a non-coherent joint transmission (NCJT). A method by a base station (BS) includes providing a user equipment (UE) with a CSI report configuration. The CSI report configuration is associated with one or more CSI reference signal (RS) resources. Each CSI-RS resource comprising a set of ports or port groups. The BS signals the UE to enable the UE to send a CSI report including CSI for more than one CSI-RS resource or for a CSI-RS resource comprising more than one port group and receives a CSI report from the UE.

Abstract: A configuration to enable a base station to schedule cross carrier scheduling of uplink and/or downlink transmissions using a DCI. The apparatus transmits, to a UE, a PDCCH including a cross carrier schedule. The PDCCH comprises DCI configured to schedule an uplink transmission or a downlink transmission. The DCI includes at least one FDRA field indicating RBs for the uplink transmission or the downlink transmission. The apparatus communicates with the UE based on the cross carrier schedule configured by the DCI.
