Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive an indicator of retransmission scheduling for a plurality of UEs, determine, based on a modulation and coding scheme (MCS) update in the indicator, resources for receiving a retransmission, and receive the retransmission on the determined resources. A base station may receive a negative acknowledgement report from at least one UE of a plurality of UEs, determine a modulation and coding scheme (MCS) update for the at least one UE, generate an indicator of retransmission scheduling for the plurality of UEs, the indicator including the MCS update for the at least one UE, and transmit the indicator.

Abstract: Base stations of neighbor cells can coordinate with each other in allocating grant-free uplink (GUL) resources for a device-to-device (D2D) connection or channel between user equipments (UEs) across the neighbor cells. The base stations coordinate to determine a condition conducive to D2D communication between the UEs. If the condition exists, the base stations coordinate to allocate network resources for D2D communication between the UEs, and establish a D2D connection between the UEs using the allocated network resources for D2D communication.

Abstract: Aspects of the present disclosure provide a mechanism for utilizing uplink hopping patterns for HARQ transmissions. Each hopping pattern may include a sequence of different frequency resources or a sequence of different scrambling sequences for a user equipment (UE) to utilize over time for HARQ transmissions. Each of the hopping patterns may further be associated with a time index mode in which the hopping pattern is applied to time resources such that each time resource within a consecutive sequence of time resources is mapped to a different frequency resource or scrambling sequence. The base station may select a hopping pattern for a particular UE and transmit an indication of the selected hopping pattern to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A base station and a user equipment (UE) may communicate in a high reliability and low latency communications system (e.g., ultra-reliable low latency communications (URLLC)). The base station may signal a UE-specific scheduling request (SR) repetition configuration that the UE may utilize to transmit an instantaneous SR when a buffer status report (BSR) is triggered by a new data packet. The UE may repeatedly transmit the SR until a number of repetitions or a time period of repetitions is met or an uplink grant is received from the base station. The SR repetition configuration may include a number of parameters including a repetition setting, power settings, a resource allocation, and an acknowledgement/negative acknowledgment (ACK/NACK) procedure.

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; and transmit, during a TTI associated with the second RAT, a first packet using the second RAT based on the switch from the first RAT to the second RAT.

Abstract: In some circumstances, a URLLC may preempt resource. An apparatus may be configured to receive a set of resource blocks from a base station including at least one of eMBB data or URLLC data in a PDSCH. The apparatus may receive a URLLC indicator from the base station. The URLLC indicator may be received embedded within the URLLC data or received separate from the URLLC data within DCI of a PDCCH. The URLLC indicator indicates whether the set of resource blocks includes at least part of the URLLC data. The apparatus may determine, based on the URLLC indicator, whether the set of resource blocks includes the URLLC data and processing the set of resource blocks based on a result of determining whether the set of resource blocks includes the URLLC data.

Abstract: Various aspects of the disclosure relate to mapping different information to different sub-channels. For example, information for different users may be mapped to different Polar code sub-channels. In some aspects, the mapping may be unbalanced in that different information is mapped to different sub-channels according to the quality (e.g., in terms of error probability) of the sub-channels and a criterion associated with the information. For example, control information for users that are experiencing the worst channel quality (e.g., in a wireless communication channel) may be mapped to the Polar code sub-channels that have the best quality.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive an indicator of resource allocation for a plurality of UEs, determine, based at least on a grouping of the plurality of UEs, resources from the resource allocation for receiving data at the UE, and receive the data on the determined resources. A base station may receive a plurality of acknowledgement reports from a plurality of UEs, determine, based on a grouping of the plurality of UEs, a resource allocation for each UE from which a negative acknowledgement was received, and transmit an indicator of the resource allocation.

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: Methods and apparatuses are disclosed for intra-cell interference management of device-to-device (D2D) communication. A plurality of user equipments (UEs) in a cell transmit a reference signal in turn in a first rotation. A scheduling entity groups the D2D connections into a plurality of clusters based on measurement reports of the reference signal such that an interference between D2D connections of different clusters is below a predetermined threshold. The scheduling entity requests the UEs of each cluster to transmit the reference signal in turn according to a second rotation such that two or more UEs corresponding to different clusters transmit the reference signal using a same network resource.
