Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a UE. The apparatus attempts to receive a downlink transmission from a base station and determines to transmit a NACK to the base station for the downlink transmission. The UE transmits the NACK to the base station in a common resource in an uplink control channel, wherein the common resource is common to multiple UEs communicating with the base station. The UE may also transmit the NACK using a resource granted to the UE in the uplink control channel. Thus, the transmission of the NACK in the common resource may comprise a repetition of the NACK transmitted using the resource granted to the UE. The common resource may comprise a Non-Orthogonal Multiple Access (NOMA) resource. Thus, the UE may apply a NOMA sequence to the NACK prior to transmission of the NACK in the common resource.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a base station, a configuration indicating a set of occasions configured for sidelink communications for the UE. The sidelink communications may include at least one of sidelink traffic, semi-persistent scheduling traffic, or a combination thereof. The UE may receive a control indication associated with a radio network temporary identifier. The control indication may include a downlink control information. In some examples, the UE may skip a first pre-scheduled occasion of the set of occasions configured for sidelink communications based on the control indication, and may perform sidelink communications during a second pre-scheduled occasion of the set of occasions after skipping the first pre-scheduled occasion.

Abstract: Various aspects described herein relate to techniques for managing downlink control information (DCI) in wireless communications (e.g., 5G NR). In an aspect, the method includes receiving a radio resource control (RRC) message, identifying a transport block size (TBS) based on the received RRC message, receiving DCI on a downlink channel with the DCI including a resource assignment, identifying a modulation order using a modulation and coding scheme (MCS) in an MCS field of the DCI, where the size of the MCS field is one bit or two bits, and calculating a coding rate based on at least the identified TBS, the identified modulation order and the resource assignment.

Abstract: Aspects of the present disclosure provide techniques to reduce overhead and improve resource management by efficiently selecting RSMA spreading code for periodic traffic in IoE devices. For example, in accordance with one technique, the IoE device, during an initial access to the base station, may notify the base station of the traffic periodicity of the IoE device such that the base station may assign a spreading code from a dedicated pool that is not utilized during the periodic access of the device. Additionally or alternatively, another technique to reduce overhead and improve resource management may include the IoE devices broadcasting the selected RSMA spreading code that the IoE devices intends to use in discovery broadcasts (DBs) along with the IoE device traffic periodicity such that the IoE devices may autonomously manage selection of RSMA spreading code that avoids collisions for the same traffic periodicity.

Abstract: Certain aspects of the present disclosure provide techniques for a multi-user data packet, such as a physical downlink shared channel (PDSCH) packet. A method by a base station (BS) includes sending a control channel, such as physical downlink control channel (PDCCH), scheduling a plurality of user equipment (UEs) for a data packet transmission and sending data for the plurality of UEs in a single transport block on the scheduled data packet. The UE receives the control channel and data packet, and determines the data in the multi-user data packet that is intended for the UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a plurality of communications from a corresponding plurality of transmission/reception points (TRPs) included in a coordinated multipoint network. At least two communications, of the plurality of communications, may have different redundancy versions from a common codebook, and may be received in a same transmission time interval (TTI). The UE may decode the plurality of communications using joint decoding. Numerous other aspects are provided.

Abstract: Network-controlled power control for side-link communications is disclosed. According to the described aspects, a power control framework is defined for network-controlled side-band or device-to-device (D2D) communications, in which transmission power for side-link communications may be stepped up enough for a base station in a connected mode with at least one of multiple user equipment (UE) devices to detect side-link communications between the UEs in order to take responsive action to enhance the reliability of the communications. The base station provides the configuration information to the UEs which may be used when preparing for transmissions of side-link traffic and/or feedback.

Abstract: Methods, systems, and devices for wireless communications are described. Wireless devices may communicate over a primary and fallback beam. To support communications over a primary and fallback beam, a preconfiguration procedure may be performed to communicate to a transmitting and receiving device the identity of the primary and fallback beam. A central scheduling node may assist in identifying the primary and fallback beam for the transmitting and receiving device. During communications, the transmitting and receiving device may switch to the fallback beam when an initial communication fails and may perform a retransmission that includes data from the initial communication over the fallback beam.
