Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a configuration for hybrid automatic repeat request (HARQ) retransmissions for semi-persistent scheduling (SPS), wherein the configuration, which is specific to the UE, identifies allocated resources of a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) for the HARQ retransmissions; and use the allocated resources identified in the configuration for the HARQ retransmissions. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for grant-free uplink communication are disclosed in which selection of a grant-free transmission format for data channel transmission may be based on link conditions. In some aspects, a user equipment identifies data for the grant-free uplink transmission, selects a grant-free transmission format from among a plurality of preconfigured grant-free transmission formats, and sends the data to a base station on the data channel using the selected grant-free transmission format. In some aspects the base station may receive channel state information from the UE and may assign a grant-free transmission format to the UE based at least in part on the channel state information. In some aspects, the base station may detect a grant-free uplink transmission on an uplink data channel, identify the UE based on a demodulation reference signal, and identify the format based on a grant-free format indicator.

Abstract: A first apparatus may perform a clear channel assessment (CCA) in a first band-operation of a first radio access technology (RAT) in the first band may be synchronized with operation of a second RAT in a second band. The first apparatus may determine whether the CCA indicates that the first band is occupied. The first apparatus may send a first switching signal in the second band based on a determination that the CCA indicates that the first band is occupied. The first apparatus may send data in the second band after the first switching signal is sent. A second apparatus may perform a CCA in a first band-operation of a RAT in the first band may be synchronized with operation of a second RAT in a second band.

Abstract: Aspects of the present disclosure relate to wireless communications and, more particularly, to linkage of packet transmissions for ultra-reliable low-latency communications (URLLC) in new radio (NR). A method for wireless communications that may be performed by a user equipment (UE) is provided. The method generally includes receiving a current transmission of a packet; determining, based on the current packet transmission, one or more previous transmissions of the packet occurred and at least one parameter associated with the one or more previous transmissions; and combining the current packet transmission with the previous transmissions based, at least in part, on the determination.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for allocating resources for the transmission of scheduling requests based on UE traffic profiles. In one embodiment, a base station determines, for one or more user equipments (UEs), a type of traffic to be exchanged between the one or more UEs and the base station. The base station allocates resources for the one or more UEs to use for sending a scheduling request based, at least in part, on the type of traffic associated with each of the one or more UEs. The base station signals an indication of the allocated resources to each of the one or more UEs.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The apparatus receives a D2D resource message based on a change in an uplink-downlink subframe configuration of at least one frame. The D2D resource message enables the apparatus to determine D2D resources allocated for D2D transmissions after the change in the uplink-downlink subframe configuration. The apparatus determines a subset of the D2D resources to be used for performing D2D transmissions based on the received D2D resource message.
