Abstract: Aspects relate to wireless communications utilizing cross carrier scheduling Methods and apparatus include generating at least one slot in a control channel from a scheduling cell, the at least one slot including a plurality of control channel segments such as PDCCH segments, which are arranged at respective times within the at least one slot. Each of the control channel segments includes control information such as DCIs corresponding to respective slots for a scheduled cell. Distributing the control channel information in segments or spans over time affords improved decoding timing in a UE in the scheduled cell.

Abstract: Aspects of the disclosure relate to a base station providing a user equipment (UE) with a sticky uplink beam assignment for one or more uplink signals. The UE may use the sticky uplink beam assignment for transmission of uplink signals until a new sticky uplink beam assignment is received. In some examples, the sticky uplink beam assignment may include an uplink beam identifier (ID) identifying an uplink beam associated with the transmission of an uplink signal. The uplink beam identified by the uplink beam ID may be used by the UE for transmission of the uplink signal and either all subsequent uplink signals (e.g., physical uplink control channel (PUCCH) and/or physical uplink shared channel (PUSCH)) or subsequent uplink signals of particular uplink channel types (e.g., dynamic PUSCH, configured grant (CG), PUCCH, etc.) until a new uplink beam ID is received. Other aspects, features, and examples are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE via a sidelink interface, a triggering signal associated with triggering hybrid automatic repeat request (HARQ) feedback for a sidelink. The UE may transmit, to the second UE and based at least in part on the triggering signal, HARQ feedback associated with the second UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may provide hybrid automatic repeat request (HARQ) feedback for multiple physical channels (e.g., multiple physical downlink shared channels (PDSCH)) scheduled via multi-component carrier. The UE may monitor control channel occasions (e.g., physical downlink control channel (PDCCH) occasions), to receive wireless communications from a base station (e.g., a next-generation NodeBs (gNB)). For example, the UE may receive multiple downlink control information (DCI) messages that may schedule multiple PDSCH over different component carriers. The UE may identify one or multiple downlink assignment indices (DAI) in the received DCI messages. In some examples, the UE may generate one or more feedback bits of a HARQ feedback codebook (also referred to as an acknowledgement codebook). The one or more feedback bits include a same number of feedback bits for each downlink assignment index associated with each DCI message.

Abstract: Methods, systems, and devices for wireless communications are described to support codebook construction for enhanced hybrid automatic repeat request (HARQ) feedback. A user equipment (UE) may be configured to support a first type of HARQ feedback and a second type of HARQ feedback that includes additional information relative to the first type. A base station may transmit multiple downlink transmissions to the UE, where a first set of the downlink transmissions may be associated with the first type of HARQ feedback and a second set of the downlink transmissions may be associated with the second type of HARQ feedback. The UE may attempt to decode the downlink transmissions and may generate respective feedback for the downlink transmissions. The UE may construct a single HARQ codebook to multiplex the different types of HARQ feedback for the downlink transmissions and may transmit the HARQ codebook to the base station.

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.

The UE may estimate one or more eCSF parameters based on the CLI channel state, the downlink channel state, two or more interference hypotheses, and at least one of a CPU specification, a timing specification, or a UE capability indication. The UE may transmit to the network node, and the network node may receive from the UE, an eCSF report based on the one or more eCSF parameters.

Abstract: Sounding reference signals (SRS) transmitted by a UE, e.g., for positioning or channel estimation, may be configured for one or both of frequency tone level cyclic shift and symbol level code, which, for example, enables multiplexing a greater number of UEs. The frequency tone level cyclic shift is produced by jointly processing a number of symbols with an extended cyclic shift structure. The SRS may be configured using a symbol group level that indicates the number of symbols associated with a cyclic shift structure, and an outer code that indicates a multiplier applied to the SRS at the symbol level, which increases the multiplexing opportunities. The symbol level code may further indicate an extended cyclic shift indicating a linear increase in phase rotation across tones in symbols associated with the symbol group level.

The example method also includes transmitting the multiple A-CSI reports to a base station in respective PUCCH in the same slot and while foregoing CSI multiplexing.
