Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein provide for priority and feedback resources for rate-split transmissions. In rate-splitting approaches, messages destined for various user equipment (UEs) may be split into a common portion and a private portion. The common portion of messages may be transmitted to multiple UEs, and each of the private portions may be transmitted to individual UEs, so that each UE may receive their entire respective messages. The network may assign different feedback resources for the common portion and the private portion of a rate-split transmission. The feedback resource for the common portion may be prior to the feedback resource for the private portion.

Abstract: A user equipment (UE) (e.g., an enhanced machine type communication (EMTC) UE) may identify several narrowbands associated with eMTC protocol based on a system bandwidth of a New Radio (NR) carrier. A base station may transmit an indication of a set of valid narrowbands for eMTC (e.g., based on coexistence considerations between eMTC and NR) to the UE. The base station may further transmit a frequency hopping pattern to the UE (e.g., associated with narrowbands within the set of valid narrowbands), and transmit one or more downlink transmissions according to the frequency hopping pattern. Additionally or alternatively, a base station may identify a subcarrier offset and/or resource block offset between resources (e.g., a resource grid) used for eMTC protocol and resources used for NR. The base station may transmit a frequency alignment parameter to the UE, and the UE may align narrowbands for eMTC accordingly.

Abstract: Methods, systems, and devices for wireless communication are described. In wireless systems supporting multiple-input, multiple-output (MIMO) transmissions, devices may implement beam-forming to improve reliability of communications. A user equipment (UE) may select a set of beams, and corresponding beam indices, for communication based on reference signals received from a base station. The UE may determine values corresponding to each of the beam indices using a scalable set of tables. For example, the UE may select a subset of the tables based on the number of selected beams, and may determine the values based on these tables. In this way, the UE may efficiently store sets of tables for multiple different configurations. The UE may sum the corresponding values to obtain a combination index value, and may transmit the combination index value to the base station. The base station may determine the selected beams based on this combination index value.

The transmission may be a noncoherent transmission. The transmission may be an uplink control information transmission, an uplink data transmission, a downlink control information transmission, or a downlink data transmission.

Abstract: Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to determine a rate-matching scheme or a feedback scheme for overlapping downlink transmission resources. A collision handling scheme may enable the UE to de-rate match a second, higher priority downlink shared channel independent of another rate-matching pattern or indicator for other shared channels, such as a first, overlapping downlink shared channel. The UE may determine to de-rate match the second channel around resources indicated within control signaling or higher-layer signaling associated with the second channel. The collision scheme may provide for the UE to generate an acknowledgement bit for feedback for one or more portions of the first channel that are preempted by the second channel and generate other feedback for non-preempted portions. A base station may keep track of preempted resources and may retransmit preempted portions of the first channel.
