Abstract: Bits for acknowledgement (ACK) and/or negative acknowledgement (NAK) may be allocated based on whether a special subframe configuration in a TDD configuration permits downlink transmission. For carrier aggregation, ACK/NAK bits may be allocated only to special subframes in component carriers (CCs) which permit downlink transmission. Also, for example, ACK/NAK bits may be allocated to all CC special subframes if a single CC is configured to allow downlink transmission on one of its special subframes. ACK/NAK bits may also be allocated to all special subframes.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., non-orthogonal multiple access (NOMA) systems), a base station may serve a large number of user equipments (UEs) on the uplink. To improve detectability for these uplink transmissions (e.g., if reference signals are not available for the transmissions), the UEs may implement parallel transmissions of preambles with uplink data. A UE may split the uplink data into one or more data layers, and may select one or more preamble layers to transmit superposed with the data layers. These preambles may be sequences known to both the UE and the base station to aid in detectability. The UE may assign different signature sequences to each of these layers based on cross-correlation values (e.g., assigning sequences with higher cross-correlation values to the data layers for improved detectability), and may scramble the layers into a single shared signal for transmission.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically to increased diversity for devices with limited communications resources. An example method generally includes transmitting data as a bundled transmission to a device with limited communications resources, the bundled transmission comprising multiple bursts wherein each burst spans a plurality of transmission time intervals (TTIs) and the same data is transmitted in each burst, and taking action to increase diversity (e.g., at least one of spatial diversity, time diversity, frequency diversity, etc.) for the bundled transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive activation or reactivation downlink control information (DCI) for a semi-persistent scheduling (SPS) configuration, wherein the activation or reactivation DCI includes a downlink association index (DAI) that is incremented by: a value of one to represent an initial SPS communication associated with the SPS configuration, or a value equal to a number of SPS occasions that are multiplexed in a same physical uplink control channel (PUCCH) communication. The UE may transmit acknowledgement or negative acknowledgement (ACK/NACK) feedback in the PUCCH communication based at least in part on the DAI. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a set of physical uplink control channel (PUCCH) resources to be used to transmit a channel state information (CSI) payload based at least in part on a first rank that is independent of a second rank used to construct the CSI payload; and transmit the CSI payload, to a base station (BS), using one or more resources from the set of PUCCH resources. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques of allocating time resources (or slots) based on a flexible pattern that allows allocation of a set of non-continuous time slots resources in an integrated access and backhaul (IAB) system. In one example, the aggregation pattern may be indicated via a single downlink control information (DCI) message that carries explicit information regarding non-continuous time slot allocation. Features of the present disclosure may also include techniques to allow for early termination of transmission between the first node and the second node when the receiver (e.g., second node) successfully receives the data channel before the end of aggregated transmission. In such situation, the first node and the second node may cease transmission after reception of an acknowledgement (ACK) message that may allow the second node to utilize the subsequent time slots for communication with its own children on the next hop (e.g., third node).

Abstract: Techniques and apparatus for transmitting control information to maintain hybrid automatic repeat request (HARQ) processes for multiple carriers in different frequency ranges, such as frequency range 1 (FR1) and frequency range 2 (FR2), in carrier aggregation scenarios are described. A first numerology of a first component carrier (CC) in FR1 and a second numerology of a second CC in FR2 are determined. A HARQ configuration that includes an indication of a set of physical uplink control channel (PUCCH) resources is determined. A number of symbols of the set of PUCCH resources is based on the first numerology and the second numerology. The HARQ configuration is transmitted to a user equipment (UE). HARQ feedback is transmitted on the first CC for data received on the second CC, using the set of PUCCH resources of the HARQ configuration.

Abstract: Aspects relate to implementing multiplexing with a single carrier waveform. In some examples, intra-symbol multiplexing of data and other information on a single carrier symbol may be implemented utilizing pre-discrete Fourier transform (DFT) multiplexing. In addition, time domain rate-matching may be performed on the data to rate-match the data around the other information based on a number of usable samples in the time domain within the symbol for the data.

Abstract: Techniques for reporting channel quality information (CQI) in a multi-carrier wireless communication system are disclosed. In one aspect, a user equipment determines one or more reporting groups, each comprising a plurality of component carriers which are configured for the user equipment. The user equipment may detect a trigger from a base station that selects a reporting group and may respond to the trigger by sending CQI for at least the activated component carriers in the selected reporting group.
