Abstract: This disclosure describes methods, devices, and systems for techniques related to wireless communications, and more particularly uplink transmissions on one or more of a physical uplink shared channel (PUSCH) and a physical uplink control channel (PUCCH). Generally, the described techniques support handling collisions between PUSCH repetitions and a PUCCH transmission. A user equipment (UE) may identify that uplink control information (UCI) is scheduled for transmission via an uplink control transmission that overlaps with multiple repetitions of an uplink data transmission. The UE may determine, for each of the multiple repetitions, a quantity of resources available for carrying multiplexed uplink control information, generate encoded UCI by encoding the UCI based on the quantity of resources available in each of the multiple repetitions, and multiplex the encoded UCI on at least a portion of the multiple repetitions based on the quantity of resources available in each of the multiple repetitions.

Abstract: Methods, systems, and devices are described for handling transmissions or channels in wireless communications that collide with one another. The described techniques relate to handling the collision between multiple overlapping channels (e.g., two or more channels of the same priority). For example, a collision resolution configuration may include resolving the collisions among the channels of the same priority first (e.g., feedback information transmissions first, and then control information), among the channels of the same service type first (e.g., normal channels first, and then low latency channel(s)), or across all of the channels of all priorities at once. Collisions may be resolved by dropping or rescheduling overlapping information from the lower priority transmission(s) or channel(s) in consideration of the higher priority transmission(s) or channel(s), or by multiplexing or piggybacking overlapping information from a first priority transmission(s) or channel(s) with a second priority transmission(s) or channel(s).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may apply an open-loop multiple-input multiple-output (MIMO) scheme among a plurality of antenna groups associated with a plurality of antennas, wherein phase coherence cannot be maintained between the plurality of antenna groups; and may apply a closed-loop MIMO scheme among antennas within each antenna group of the plurality of antenna groups, wherein phase coherence can be maintained between antennas included in each antenna group of the plurality of antenna groups. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include receiving radio resource control signaling configured with a first set of demodulation reference signal parameters for transmission of an uplink data channel of a type, receiving downlink control information of a format to activate the transmission of the uplink data channel, identifying a second set of demodulation reference signal parameters for transmission of the uplink data channel of the type based on the received downlink control information, and activating the transmission of the uplink data channel using the first and second set of demodulation reference signal parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may identify multiple demodulation reference signal (DMRS) symbols corresponding to multiple DMRS ports of a multiple input multiple output configuration. The transmitting device may generate multiple phase-rotated and precoded DMRS symbols by applying an orthogonal cover code, a phase rotation scheme, and a precoding matrix to the identified DMRS symbols. The transmitting device may map the phase-rotated and precoded DMRS symbols to time-frequency resources corresponding to multiple antenna ports, and transmit a DMRS based on the mapped phase-rotated and precoded DMRS symbols. The transmitting device may transmit the DMRS using multiple antennas that correspond to the antenna ports.

Abstract: Methods, systems, and devices for wireless communication are described. In one example, a base station may dynamically configure a user equipment (UE) to monitor or avoid monitoring for a preemption indication. Accordingly, the UE may have a lower chance of monitoring for a preemption indication when it is unlikely that an uplink or downlink transmission will be preempted. In another example, a base station may transmit a control message indicating whether future indications received from the base station are to be interpreted as preemption indications or permission indications. Accordingly, the base station may choose to use either preemption indications or permission indications (e.g., based on the probability of collisions between mobile broadband (MBB) and low latency transmissions) to facilitate MBB and low latency communication multiplexing with limited signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A transmission reception point (TRP) may determine a configuration for downlink transmission of group-common control information associated with a plurality of TRPs. The TRP may identify a set of downlink resources allocated for transmission of the group-common control information. A user equipment (UE) may receive the configuration from at least one TRP of the plurality of TRPs. The UE may monitor downlink resources for reception of the group-common information based on the configuration. The TRP may transmit, and the UE may receive, the group-common control information over the downlink resources. The group-common control information may indicate communication parameters for communications between the UE and at least one TRP.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message configuring the UE to communicate coordinated transmissions with multiple transmission reception points (TRPs) using a first coordinated transmission mode of a set of different coordinated transmission modes. The UE may receive, based on the configuration message, downlink control information including at least one indicator and receive a first coordinated transmission communicated in accordance with the first coordinated transmission mode. The UE may transmit, in accordance with a feedback configuration corresponding to the at least one indicator and the first coordinated transmission mode, a feedback message for the first coordinated transmission to at least one of the multiple TRPs.

Abstract: Methods, systems, and devices that support an efficient sequence-based polar code description are described. In some cases, a wireless device (e.g., a user equipment (UE) or a base station) may transmit a codeword including a set of information bits encoded using a polar code or receive a codeword including a set of information bits encoded using a polar code. As described herein, the wireless device may determine the bit locations of the information bits in the polar code based on a partition assignment vector. Specifically, the wireless device may partition bit-channels for one or more stages of polarization and assign information bits to partitions based on the partition assignment vector. Once the bit locations of the information bits are determined, the wireless device may decode a received codeword or transmit an encoded codeword based on the determined bit locations of the information bits.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) and a network entity may utilize multi-port mobility reference signals to assist with spatial based mobility procedures. The UE may receive a reference signal that is associated with multiple antenna ports. The UE may measure a multi-dimensional channel response based on the reference signal. The multi-dimensional channel response may be associated with measured channel metrics corresponding to the multiple antenna ports. The UE may transmit a report that includes a channel measurement vector based on the multi-dimensional channel response. The channel measurement vector may indicate multiple measured channel metrics for one or more dimensions of the multi-dimensional channel response. The network entity may transmit a message that indicates one or more metrics associated with mobility management for the UE based on the report that indicates the channel measurement vector.
