Abstract: Methods, systems, and devices are described for wireless communications. A first CSI reporting configuration may be used for communications using TTIs of a first duration and a second CSI reporting configuration may be used for communications using TTIs of a second duration. A determination of whether to report CSI based on the first and/or second configuration may be made, and a CSI report may be transmitted based on the determination. In some cases, CSI for the first CSI reporting configuration is determined differently than CSI for the second CSI reporting configuration. For instance, the CSI reporting configurations may use different reference resources and/or reference signal resources when calculating respective CSI. In some cases, the first and second CSI reporting configurations may be configured as a first CSI process and a second CSI process, which may be operated either independently or jointly.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications network may set priorities for cell groups in dual connectivity. A higher priority cell group may reserve slots and indicate the reserved slots to the lower priority cell group, for example by a backhaul connection. The high priority cell group may also indicate additional, non-reserved slots, which the lower priority cell group may reserve or use for scheduling. One of the cell groups may transmit a slot format indication (SFI) to a user equipment (UE) in the dual connectivity to indicate the slot reservations. In some cases, a hybrid automatic repeat request (HARQ) timing parameter may be based on a number of reserved slots. In some cases, power control may be varied based on whether the UE is capable of simultaneous uplink and downlink transmission.

Abstract: Methods, systems, and devices for wireless communication for adaptive ultra-reliable low-latency communications (URLLC) semi-persistent scheduling (SPS) are described. One method includes determining a data packet payload size for a transmission using SPS resources in a transmission time interval (TTI). The method also includes sending a release signal to release a portion of the SPS resources in the TTI based on the size and transmitting the data packet during the TTI using unreleased SPS resources. Another method includes identifying that a packet profile of packets transmitted on SPS resources varies by more than a packet profile threshold and sending, based at least in part on the identifying, a request-to-update (RTU) signal to update the SPS resources. The method also include receiving a confirmation of receipt of the RTU signal and updating a resource allocation or a resource attribute based at least in part on the packet profile and confirmation of receipt.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a method for managing SRS transmission in a bandwidth part may include identifying one or more bandwidth parts of a component carrier of a cell to be allocated to a user equipment (UE). The method may also include identifying a sounding reference signal (SRS) bandwidth configuration for each of the one or more bandwidth parts. The method may further include transmitting the SRS bandwidth configuration to the UE. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide a mechanism for rate-matching between overlapping resource block (RB) sets within a transmission time interval (TTI). A physical downlink control channel (PDCCH) carrying downlink control information (DCI) including a downlink assignment for scheduling a physical downlink shared channel (PDSCH) may be received by a user equipment (UE) within the TTI. In some examples, the DCI may be included within control channel elements (CCEs) located within shared resource elements between two overlapping RB sets. If the CCEs forming a decoding candidate over which the DCI may be detected are entirely contained within the shared resource elements, the UE may perform rate-matching around the two overlapping RB sets.

Abstract: Various devices, methods, and processes are provided for handling conflicting and/or redundant power control and triggering information for transmitting reference signal(s) such as sounding reference signal (SRS) using carrier aggregation (CA). A user equipment (UE) receives a first downlink control information (DCI) and a second DCI including SRS control information that is in conflict with that of the first DCI, for controlling SRS transmission on a component carrier (CC). The UE determines a resolution to reconcile the conflict between the DCIs. Then the UE can transmit an SRS on the CC in accordance with the resolution.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify one or more time slots in which a first communication on a multi-slot physical uplink control channel (PUCCH) overlaps with a second communication on another PUCCH. The UE may transmit, for each time slot of the one or more time slots, the first communication or the second communication based at least in part on a first priority assigned to the multi-slot PUCCH and a second priority assigned to the other PUCCH. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive a first set of grants for performing uplink transmissions between the UE and a first group of cells associated with a first radio access technology (RAT) and a second set of grants for performing uplink communication between the UE and a second group of cells associated with a second RAT. The UE may determine that a combined transmit power exceeds a total power limit or that there may be a potential of the combined power exceeding the total power limit. The UE may further perform the uplink communication with the first group of cells using the first RAT and the second group of cells using the second RAT.

Abstract: Aspects of the present disclosure provide hybrid automatic repeat request (HARQ) techniques for enhanced machine type communication (eMTC). In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE) for determining a HARQ ID. The method generally includes determining a HARQ ID based, at least in part, on a coverage enhancement (CE) level, and performing a HARQ process timeline based, at least in part, on the determined HARQ ID. Another method is provided for determining a subframe to transmit feedback. The method generally includes determining at least one subframe to transmit a physical uplink control channel (PUCCH) to acknowledge one or more downlink transmissions based, at least in part, on availability of uplink subframes following one or more downlink subframes carrying the downlink transmissions to be acknowledged and transmitting the PUCCH in the determined at least one subframe.
