Abstract: Methods, systems, and devices for wireless communications are described. A first device may obtain information indicative of a configuration to provide code block group (CBG)-based feedback for one or more semi-persistent scheduling (SPS) communications scheduled for the first device. The first device may then monitor for the one or more SPS communications in one or more CBGs of a TB in accordance with one or more SPS communication configurations. Based on the monitoring of the semi-persistent scheduling communications, the first device may generate one or more feedback bits associated with the one or more SPS communications, and may communicate, with a second device, the one or more feedback bits associated with the one or more SPS communications in accordance with the configuration to provide CBG-based feedback.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for DMRS allocation in sub-band FD. For transmission of UL data in a set of symbols having UL DMRS in at least one symbol, a UE may determine which symbol(s) in a subframe will receive DL DMRS so that the UE may align the transmission of the UL DMRS with a reception of the DL DMRS. For transmission of DL data in a set of symbols having a DL DMRS, a BS may determine for a first subset of symbols that a PUSCH will be received from the UE or determine for a second subset of symbols that a PUSCH will not be received from the UE. The BS insert a DL RS within the first subset of symbols or the second subset of symbols based on the determination regarding the PUSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity (e.g., a base station or reader) may transmit an initial access trigger message (e.g., modulating a continuous wave transmission using amplitude shift keying (ASK)), and the trigger message may include an indication of a type of passive user equipment (PUE) or a PUE use case (e.g., high priority/latency-critical PUEs or low priority/latency non-critical PUEs). A receiving PUE may harvest energy from the initial access trigger message for transmitting an initial access response message including an identifier for the receiving PUE. The receiving PUE may transmit the initial access response message (e.g., on one or more initial access resources) using the harvested energy if the trigger message indicates the PUE's type of PUE or PUE use case. In some examples, the receiving PUE may ignore triggers for different types of PUEs or PUE use cases.

Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described in which multiple devices may implement sidelink communications for direct device-to-device exchange of information. Such devices (e.g., user equipment (UE) devices) may be configured with resources for sidelink communications, and may monitor for a sidelink preemption indication (SPI) from a base station and determine whether one or more sidelink communications is preempted based on the SPI.

Based on an indication in a received SPI, it may be determined whether or not to transmit sidelink feedback. The sidelink feedback may be transmitted to one or more other sidelink devices, or to a base station, and preemption of the sidelink feedback may be determined based on one or more parameters associated with the sidelink communications, associated with the SPI, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may transmit feedback, such as hybrid automatic repeat request (HARQ) 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 are provided to support payloads for msgA transmission in a two-step random access (RACH) procedure by providing a one-to-many mapping arrangement between preambles and physical uplink shared channel (PUSCH) resource units (PRUs). A preamble is determined by the UE which is mapped to one or more groups of PRUs to support piggybacking of uplink control information (UCI), frequency hopping on PUSCH, and multiple-slot repetition for msgA transmissions. By piggybacking UCI to a payload in msgA, flexibility may be provided in the selection of MCS and waveform as well as resource allocation for demodulation reference signals (DMRS) and PUSCH in PRUs. Moreover, by allowing a payload to hop to different frequencies on PUSCH during the transmission of msgA, a gain in frequency diversity and interference averaging may be provided, and by enabling a payload to repeat across multiple slots in msgA transmission, coverage enhancement and/or reliability may be increased.

Abstract: Aspects are presented that enable a user equipment (UE) to perform simultaneous transmission of supplementary uplink carriers. The UE can transmit, to a base station, a capability message of the UE, the capability message indicating whether the UE supports simultaneous transmission of uplink signaling on supplementary uplink carriers. The UE can receive, from the base station, schedule information scheduling simultaneous transmission of a first uplink transmission on a first carrier in a first cell and a second uplink transmission on a second carrier in a second cell different from the first cell based on the capability message. The UE can transmit, to the base station, the first uplink transmission on the first carrier via the first cell simultaneous with the second uplink transmission on the second carrier via the second cell.

Abstract: Methods, systems, and devices for wireless communications are described. Feedback based codebooks for reducing or eliminating interference between orbital angular momentum (OAM) based backhaul communications between a first network node and a second network node and access communications between the first network node and a user equipment (UE) are described. The first network node may transmit a message to a UE indicating a feedback codebook for a set of reference signals associated with OAM modes. The first network node may transmit the reference signals, where each reference signals may be associated with a respective OAM mode. The UE may generate and indicate in a feedback report to the first network node codewords corresponding to UE feedback for the received reference signals. The first network node may communicate with the UE via an access link and with the second network node via a backhaul link based on the feedback report.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a payload for inclusion in an uplink transmission. The UE may organize the payload into a code block group (CBG) that includes one or more code blocks (CB). The UE may map each CB of the CBG to a corresponding uplink shared channel resource unit (e.g., a physical uplink shared channel resource unit) of an uplink transmission occasion of the first UE. The uplink transmission occasion may also be shared with one or more additional UEs such that the CBG of the first UE is multiplexed with additional CBGs from the additional UEs. The UE may transmit, to a base station, the uplink transmission including each uplink shared channel resource unit on which the CBG is organized.

Abstract: During positioning of a user equipment (UE), (DL) positioning reference signals (PRS) transmitted by one or more transmission reception point (TRP) in a wireless communication system may be preempted or punctured by higher priority transmissions, such as ultra-reliable low-latency traffic (URLLC). A PRS preemption indication (PI) may be provided to a UE identifying one or more TRPs affected by preemption. The PRS PI may further identify the time domain and frequency domain of the preempted DL PRS transmissions. The PRS PI may identify the time domain, e.g., based on a number of PRS symbols between two monitoring occasions, wherein only PRS symbols that contain positioning reference signals associated with the group of TRPs are counted. The PRS PI may identify the frequency domain by identifying at least one of four or more frequency sub-bands of the preempted DL PRS transmissions.
