Abstract: Wireless communications systems and methods related to managing interference among feedback transmissions are provided. A first wireless communication device receives, from a second wireless communication device, a first forward data transmission request signal over a first link in a first link direction, wherein the first forward data transmission request signal is associated with a first feedback transmission over the first link in a second link direction opposite the first link direction. The first wireless communication device yields, in response to the first forward data transmission request signal, access to a channel resource for the first feedback transmission based on at least an interference tolerance level of the second wireless communication device and an interference level on the first feedback transmission from the first wireless communication device

Abstract: Various types of communication may switch from an unlicensed spectrum to a licensed spectrum. MiCr communication may be synchronized based on transmission time intervals (TTIs), which may improve the duration required to switch between bands. A MiCr system may transmit a signal to temporarily suspend other traffic in a licensed band so that MiCr communication may occur. For example, an apparatus may be configured to determine synchronization between a first radio access technology (RAT) and a second RAT based on transmission time intervals associated with the first RAT and transmission time intervals associated with the second RAT, switch from the first RAT to the second RAT after the determined synchronization between the first RAT the second RAT. Further, the apparatus may transmit a silencing signal to suspend traffic in the second RAT.

Abstract: Certain aspects of the present disclosure provide techniques for support response-based resource management. A UE may determine an uplink response to be transmitted in response to a downlink transmission by a first TRP participating in CoMP to the UE with a second TRP. The first UE may select which of the first TRP or the second TRP to transmit the uplink response to, based at least in part on the determined uplink response and may transmit the uplink response to the selected first or second TRP.

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.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of one or more resources, assigned to multiple UEs, to be used to transmit a channel quality indicator (CQI) report; receive an indication of a threshold value associated with a range of channel conditions corresponding to a modulation and coding scheme (MCS) being used to communicate with the UE; and selectively transmit the CQI report on the one or more resources based at least in part on whether a measured channel condition is outside of the range of channel conditions by at least the threshold value. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. A traffic window may be scheduled for a user equipment (UE) base on semi-persistent scheduling (SPS). In various situations, all or a portion of a first communication to be transmitted or received can be transmitted or received during an SPS grant in the traffic window. If useful, additionally, a remainder of the first communication not transmitted or received during the SPS grant may be transmitted in an on-demand grant appended to the SPS grant. The on-demand grant can be in a same subframe as the SPS grant. When the BS appends the on-demand grant to the SPS grant, the BS may transmit, and the UE may receive, an indicator indicating that the on-demand grant has been appended to the SPS grant. Numerous other aspects are provided.

Abstract: Aspects of the disclosure relate to distributed joint access of an unlicensed sidelink channel. Each sidelink device may perform independent and asynchronous listen before talk (LBT) of the unlicensed sidelink channel with a respective back-off time. The first sidelink device to complete back-off may transmit a joint access synchronization (JAS) signal indicating a duration of time that the unlicensed sidelink channel may be accessed by sidelink devices. Synchronized access sharing of the unlicensed sidelink channel across different active sidelinks may then be achieved through distributed handshake signaling.

Abstract: Methods, systems, and devices for wireless communications are described techniques for configuring channel state information (CSI) process for a coordinated set of transmission reception points. The techniques for configuring channel state information (CSI) process for a coordinated set of transmission reception points may include receiving a sounding reference signal (SRS) and identifying, based at least in part on the SRS, a first CoMP set of TRPs. The techniques for configuring channel state information (CSI) process for a coordinated set of transmission reception points may also include transmitting a CSI-RS to a UE and receiving CSI from the UE. The techniques for configuring channel state information (CSI) process for a coordinated set of transmission reception points may further include identifying, based at least in part on the CSI, a second CoMP set of TRPs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a communication from a transmission/reception point (TRP), included in a coordinated multipoint network, was not successfully received. The UE may transmit a plurality of negative acknowledgements (NACKs), corresponding to the communication, to a plurality of TRPs included in the coordinated multipoint network based at least in part on determining that the communication was not successfully received. The UE may receive a retransmission of the communication from one or more TRPs of the plurality of TRPs. Numerous other aspects are provided.
