Abstract: Methods, systems, and devices for wireless communications are described. According to one or more aspects, a device, such as a user equipment (UE), may receive, from one or more base stations during a first time unit, a control signal including an indication of a reference signal bundling configuration associated with one or more physical channel types which may be potentially scheduled during a set of time units after the first time unit. The UE may determine the set of time units based on the indication of the reference signal bundling configuration. Additionally or alternatively, the UE may receive scheduling configuration of one or more physical channels, and the one or more physical channels during one or more second time units of the set of time units. The UE may then bundle the one or more physical channels based on the reference signal bundling configuration.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station or other network entity may allocate uplink resources to UEs, or groups of UEs, that are subsequently reallocated. For example, a base station may determine a reallocation of uplink resources and issue a cancellation or preemption indication that may correspond to at least a portion of the previously-allocated resources (e.g., as allocated to particular UEs). UEs may be configured to monitor for cancellation or preemption indications, and based on received cancellation or preemption indications, UEs may determine whether or not to proceed with an uplink transmission using their previously-allocated uplink resources.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for configuring group indices for uplink transmissions from a user equipment (UE) such that the UE may be able to determine whether to combine uplink transmissions scheduled on overlapping time resources. Specifically, the UE may combine uplink transmissions associated with a same group index for transmission in a single channel, and the UE may avoid combining uplink transmissions associated with different group indices. In some cases, the indication of a group index associated with an uplink transmission from a UE may be explicit (e.g., provided in a downlink control information (DCI) message), and, in other cases, the indication of a group index associated with an uplink transmission from a UE may be implicit (e.g., corresponding to a resource allocated for the uplink transmission).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink transmission via at least one of a primary cell, a secondary cell, or a combination thereof. The UE may identify a feedback indication for the downlink transmission. The UE may transmit a first feedback message that includes the feedback indication via the primary cell. The UE may transmit a second feedback message that also includes the feedback indication via the secondary cell.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a high priority uplink control information (UCI) message, a low priority UCI message, and an uplink shared channel message overlap. The UE may select a first set of resources on the physical uplink shared channel for the high priority UCI message then select a second set of resources on the physical uplink shared channel for the low priority UCI message. The second set of resources may be non-overlapping with the first set of resources. The UE may transmit the high priority UCI message on the first set of resources, the low priority UCI message on the second set of resources, and the uplink shared channel message on a third set of resources on the physical uplink shared channel.

Abstract: Some aspects described herein relate to determining a length for a sequence for communicating a signal, determining a reduced length as a largest prime number that is smaller than a fraction of the length, generating a Zadoff-Chu sequence based on the reduced length, extending the Zadoff-Chu sequence to be of the length to generate the sequence of the length, and communicating the signal based on the generated sequence.

Abstract: A spatial multiplexing configuration may enable a user equipment (UE) to spatially multiplex two or more uplink channels of different types for simultaneous transmission. For example, a UE may receive an indication of a spatial multiplexing configuration from a base station. The UE may identify two or more uplink channels for simultaneous transmission on a same component carrier, where each uplink channel may be a different type. In such cases, the UE may spatially multiplex the two or more uplink channels on a same set of time/frequency resources on the component carrier in accordance with the spatial multiplexing configuration. The spatially multiplexed uplink channels may then be simultaneously transmitted by the UE on the set of resources, where the spatially multiplexed uplink channels may be simultaneously sent to the same base station or to different base stations. Additionally, different spatial parameters may be applied to each uplink channel.

Abstract: Methods, systems, and devices for wireless communications are described that provide for service indication via downlink control information (DCI) in which different services have a same DCI size. Techniques provide also that a DCI format may be indicated by a masking operation on a cyclic redundancy check (CRC) of the DCI. The DCI may include an indicator field that may indicate the service of the associated operation. The indication may also be provided via different monitoring occasions of the DCI transmissions that are associated with different services. Different DCI search spaces also may be associated with different services and provide the service indication. Additionally or alternatively, different scrambling sequences used on all or a portion of control information or demodulation reference signal transmissions may be associated with different services.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may filter a group of uplink reference signals so that filtering delays of the group of uplink reference signals are consistent based at least in part on a filtering constraint for the group of uplink reference signals; and transmit the group of uplink reference signals. Numerous other aspects are provided.

Abstract: Systems and method for configuring and providing uplink control information (UCI) multiplexing on physical uplink shared channel (PUSCH) transmissions are disclosed. In embodiments, a base station configures and signals, to a user equipment (UE) a plurality of sets of beta-offset values to be used by the UE for multiplexing a UCI transmission of a first priority to a PUSCH transmission of a second priority. Each set of the plurality of sets of beta-offset values is configured based on the second priority of the PUSCH transmission. In embodiments, the UE determines whether the UCI transmission of the first priority is allowed to be multiplexed to the PUSCH transmission of the second priority, and multiplexes the UCI to the PUSCH when multiplexing of the UCI and PUSCH is allowed, using a beta-offset value from the plurality of sets of beta-offset values. Other aspects and features are also claimed and described.
