    Abstract: Techniques are described for wireless communication. One method for wireless communication includes transmitting, to a user equipment (UE), an indication of a control channel subcarrier spacing to be used by the UE; and transmitting a control message having a subcarrier spacing in accordance with the indication. Another method for wireless communication includes transmitting, to a UE, an indicator channel identifying at least a subcarrier spacing to be used in one or more subsequent control channels. One or more subsequent control channels are then transmitted in accordance with the subcarrier spacing indicated by the indicator channel.

    Abstract: Various aspects are described for schemes that address the potential puncturing of important reference signals (RSs) for enhanced mobile broadband (eMBB) applications, such as demodulation reference signal (DMRS), channel state information reference signal (CSIRS), tracking reference signal, and general reference signal. The schemes can be used for recovery of eMBB's RS puncturing from dynamic multiplexing of ultra-reliable-low-latency communications (URLLC) and eMBB. The schemes include a block-based scheme and an over-provisioning scheme. The schemes modify an existing RS pattern before puncturing occurs in response to a presence of the URLLC traffic. In addition, there can be an option not to use (e.g., disable) time-domain orthogonal cover code (TD-OCC) for the RSs.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may identify a collision between a first resource for a downlink semi-persistent scheduled communication and a second resource for another downlink signal; and perform an action to mitigate the collision based at least in part on identifying the collision. In some aspects, a user equipment (UE) may identify a collision between a first resource for a downlink semi-persistently scheduled (SPS) communication and a second resource for another downlink signal; and determine an action, to be performed by a base station, to mitigate the collision based at least in part on identifying the collision; and selectively receive the downlink SPS communication or the other downlink signal based at least in part on the determination. Numerous other aspects are provided.

    Abstract: A first apparatus may puncture, in at least two subslots, a first type of data or control information with a second type of data or control information. The first apparatus may bundle the least two subslots within a subframe, and the subframe may include a portion for carrying acknowledgment (ACK)/negative acknowledgment (NACK) information associated with the second type of data or control information. The first apparatus may communicate with a user equipment (UE) during the at least two subslots within the subframe. A second apparatus may receive ACK/NACK information associated with a second type of data or control information. The second apparatus may reduce a transmission power for a first type of data or control information during a subsequent subframe when the ACK/NACK information indicates a negative acknowledgement.
