Abstract: Certain aspects of the present disclosure provide techniques and apparatus for signaling channel preemption indications that enable a user equipment (UE) of a first type to take one or more actions on resources that are re-allocated to an UE of a second type. An exemplary method generally includes determining that resources allocated for a scheduled transmission by a first user equipment (UE) of a first type overlaps with uplink channel resources allocated to a second UE of a second type. The method also includes signaling, based on the determination, an uplink preemption indication (ULPI), to the second UE, that identifies at least some of the overlapping resources.

Abstract: This disclosure provides systems, methods and apparatus for assisting a user equipment (UE) with balancing quality of service (QoS) requirements (such as access latency or reliability requirements) and consumption of high priority network resources (such as for load balancing) when transmitting a random access message (RAM) in a two-step random access channel (RACH) procedure. As a result, the UE may be capable of satisfying QoS requirements for the RAM while reducing an impact of transmission of the RAM on other uplink transmissions. Furthermore, some techniques and apparatuses described herein assist a UE with prioritizing portions of the RAM in different UE operating modes, such as a dual connectivity mode, a carrier aggregation mode, or a supplemental uplink mode. Some techniques and apparatuses described herein employ cross-carrier scheduling, dynamic power sharing, or dynamic power control to achieve these and other performance improvements.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for enabling a wireless system implementing multicast transmissions to control feedback reports from multiple user equipments (UEs) and to address feedback codebook misalignment issues. In particular, aspects provide for multicast transmission grants including multiple feedback timing indicators (K1) in which the multicast transmission grants are configured to configure different UEs for multicast transmission feedback reporting in which feedback codebooks transmitted in various uplink control transmission occasions from the different UEs have a same size. Other aspects and features are also claimed and described.

Abstract: Comb adaptation for interlaced frequency division multiplex (IFDM) demodulation reference signals (DMRS) is discussed. Transmission configuration for DMRS may be assigned to UEs with a coded combination of cyclic shift, OCC, and comb value. Some assigned combinations provide for a different comb value to be used for the different slots in the same subframe. Further aspects provide additional interference randomization through comb shifting, using inter-subframe hopping functions. Additionally, where retransmissions are present without uplink grant, the UE may select comb values for retransmissions based on the counter number for the retransmissions, which are different than the comb values used for the original DMRS transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. In some implementations, a method for wireless communication at a user equipment (UE) is described that includes identifying that the UE is in carrier aggregation communication with a primary and secondary cell. The method may also include monitoring, during one or more time intervals, UE-specific search spaces of the secondary cell for control information scheduling data communications on the primary cell. The method may include switching, during one or more different time intervals, to monitoring UE-specific search spaces of the primary cell. Another method describes wireless communication at a base station that may configure a UE to communicate via carrier aggregation, transmit control information via the secondary cell to the UE during downlink TTIs, and transmit control information via the primary cell to the UE during uplink TTIs.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication. The techniques include a method wireless communication by a user equipment including receiving a configuration message, wherein the configuration message in part configures the UE to communicate coordinated transmissions with a plurality of transmission reception points using a coordinated transmission mode. The method further includes, receiving one or more physical downlink shared channel transmissions from a plurality of transmission reception points in accordance with the coordinated transmission mode. The method further includes, selecting a HARQ-ACK feedback mode based in part on the coordinated transmission mode. The method further includes, transmitting HARQ-ACK feedback to at least one of the plurality of transmission reception points using the selected HARQ-ACK feedback mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive a broadcast message from a base station, the broadcast message including an indication pertaining to system information for reduced-capability UEs including UEs with a bandwidth capability below a threshold, the UE being a reduced-capability UE. The UE may determine, based on the indication in the broadcast message, whether system information for reduced-capability UEs is scheduled to be broadcast by the base station. The UE may then obtain the system information for reduced-capability UEs in accordance with the indication in the broadcast message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station as part of a wireless communications system. The UE may identify a configuration for one or more repetitions of an uplink control channel transmission, where each repetition of the one or more repetitions including a first quantity of symbols indicated by the configuration. The UE may determine a quantity of resource blocks for each repetition of the one or more repetitions. The UE may then identify that a second quantity of symbols is available to the UE to transmit a repetition of the one or more repetitions, and the second quantity of symbols may be less than the first quantity of symbols. The UE may transmit, to a base station, the repetition on the using the quantity of resource blocks for each repetition with the first quantity of symbols.

Abstract: Methods, systems, and devices for wireless communication are described. A base station and user equipment (UE) may utilize different slot structures for communications depending on the type of data to be transmitted. A base station may configure the slot structures based on a capability of a UE or operation conditions. The base station may identify a slot structure for a first slot, which may be group-specific or UE-specific, and determine a slot structure for a subsequent slot, which may be UE-specific or based on the slot structure of the first slot. A set of slot structure combinations may be identified to be used by a UE for combining the first and subsequent slots, and one combination may be selected based on a capability of the UE, an operation to be performed by the UE, an operational condition associated with the UE, or a combination thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a dual connectivity configuration for a plurality of communication links, where at least one communication link of the plurality of communication links includes a sidelink. The UE may transmit a report based on an event associated with the sidelink. In some cases, the UE may determine the event associated with the sidelink based on identifying an activation of the at least one additional sidelink carrier, establishing a relay communication link between the UE and a relay network node, measuring a set of path loss values, determining a minimum path loss value of the measured set of path loss values, determining a backoff value for one or more sidelink carriers, or any combination thereof.
