Abstract: Techniques are described herein for determining a priority ranking for channel state information (CSI) reports based at least in part on a reliability parameter, a latency parameter, or both of resources allocated to a user equipment (UE). In some wireless communications systems, ultra reliable low latency communication (URLLC) services may be interspersed with enhanced mobile broadband (eMBB) services. The UE may perform a CSI report prioritization procedure to account for reliability parameters, latency parameters or both. In some cases, CSI reporting for resources associated URLLC services may receive higher priority than CSI reporting for eMBB services. The UE may be configured to determine reliability parameters and/or latency parameters based on signaling received from the network or from determining changes to one or more configurations of the UE. In some cases, the priority ranking of the CSI report may be based at least in part on a slot set identifier.

Abstract: Certain aspects of the present disclosure provide techniques for indicating unoccupied data channel occasions for semi-persistent scheduling of wireless data communications. One aspect provides a method for wireless communication by a user-equipment (UE). The method generally includes: receiving, from a base station (BS), scheduling of resources for reception of multiple data channels; determining, based on a resource for a first data channel of the multiple data channels, an indication of whether transmission of at least a second data channel of the multiple data channels will be skipped; and taking one or more actions associated with communication with the BS in accordance with the indication.

Abstract: This disclosure provides systems, methods, apparatuses, and computer-readable media for multiplexing channel state information (CSI) reports in scenarios involving multiple transmit-receive points (TRPs). In one aspect, a user equipment (UE) may receive at least one configuration that identifies a resource for multiplexing CSI reports that have a potential to collide in a slot. The UE may receive the at least one configuration from either, or both, of a first TRP or a second TRP. The UE may transmit at least one of a first set of CSI reports to the first TRP or a second set of CSI reports to the second TRP, multiplexed in the resource, according to the at least one configuration.

Abstract: Methods, systems, and devices for wireless communications are described that support demodulation reference signal (DMRS) multiplexing scheme selection for uplink transmission. A user equipment (UE) may monitor for a parameter from a base station indicating which DMRS scheme to use. In some cases, the base station may transmit a radio resource control (RRC) parameter indicating a first DMRS scheme to the UE. The UE may select the first DMRS scheme based on receiving the RRC parameter from the base station or based on a default DMRS scheme. The UE may transmit a transmission based on the first DMRS scheme.

Abstract: Methods, systems, and devices for wireless communications are described. Pre-discrete Fourier transform (DFT) time-domain spreading codes may be applied for UE multiplexing for uplink control information (e.g., over shared resources of an uplink slot). For example, a moderate number of UEs may be multiplexed within the same slot by having each UE spread modulation symbols before DFT-spreading by different spreading code. For orthogonality across UEs, the pre-DFT spreading codes may be selected as orthogonal cover codes (OCCs). The spreading sequences can be generated from a set of any orthogonal sequences or generated from unitary matrices. In some cases, orthogonality in the time domain may be kept as well as a frequency division multiplexed (FDM) structure in the frequency domain. For such property, a Fourier basis OCC design may be used. In some other examples, a Hadamard matrix based OCC design may be used.

Abstract: Certain aspects of the present disclosure provide techniques for replacing and/or fixing broken uplink repetitions due to segmentation of nominal repetitions into actual repetitions. A method that may be performed by a user equipment (UE) includes detecting that a configured repetition pattern for uplink transmission to a network entity results in segmentation of at least one nominal repetition into multiple actual repetitions, modifying the configured repetition pattern, based at least in part on the detection, to avoid segmentation of nominal repetitions into multiple actual repetitions, and sending the uplink transmission to the network entity in accordance with the modified repetition pattern.

Abstract: Aspects are provided which allow a base station to segment a code block into individual code block segments and a UE to determine and indicate a quality of the individual code block segments in a CSI report to a base station. The base station transmits a code block to the UE which includes a plurality of code block segments. The UE determines a code block segment quality of each of the code block segments, and sends a CSI report including one or more of the code block segment qualities to the base station. Thus, the code block segment qualities indicated by the UE allow the base station to determine which segments of the code block should be re-transmitted, for example, based on a best RV to be applied for the code block retransmission, thereby improving retransmission performance.

Abstract: Methods, systems, and devices for wireless communications are described. Feedback information associated with decoding downlink information may be reported in a first stage and a second stage. A size of the second stage may be restricted by an upper limit associated with an available set of uplink resources for transmitting the feedback information. Limiting the size of the second stage may include reducing a size of second information generated for the second stage, yielding third information for the second stage. The third information may be transmitted with first information generated for the first stage. Limiting the size of the second stage may also include generating second information having a reduced size based on determining that the upper limit may be exceeded. The reduced-size second information may be transmitted with the first information.

Abstract: Techniques and device for wireless communications are described. A wireless device may establish multiple connections with multiple transmission reception points (TRPs). The wireless device may receive downlink control information (DCI) messages from the multiple transmission points and may generate joint hybrid automatic repeat request feedback (HARQ) based on the received downlink control information messages. To support joint HARQ feedback, counter indices may be jointly assigned to the DCI messages generated by the multiple transmission reception points. The method for jointly assigning the DCI messages may be selected based on a level of interference detected in a communications channel. Also, to support joint HARQ feedback, a total counter index in an uplink DCI message may be configured to indicate a total number of DCI message transmitted from a first TRP and a second TRP during a time period.

Abstract: Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Techniques are described herein for performing out-of-order processing. The UE may receive a first downlink channel at a first time and a second downlink channel at a second time. The UE may determine that a priority of the second downlink channel is different (e.g., higher) than a priority of the first downlink channel. The UE may determine that a first uplink transmission associated with the first downlink channel is to be transmitted after a second uplink transmission associated with the second channel based on the different priorities. The UE may set one or more operations based on these determinations. In some cases, the UE may suspend processing the of the first downlink channel to process the second downlink channel.
