    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for narrowband communications using frequency hopping in an unlicensed frequency band. In some aspects, a base station (BS) and a user equipment (UE) may communicate with one another over a sequence of unique frequency sub-bands of a frequency hopping pattern. In some instances, the BS and the UE may switch from a current frequency sub-band to another frequency sub-band based on a number of unsuccessful attempts to gain access to the current frequency sub-band. In some other instances, the BS and the UE may communicate data using configured grant (CG) resources based on a number of unsuccessful attempts to gain access to the current frequency sub-band.

    Abstract: Methods, systems, and devices for wireless communications are described. In some systems one or more first user equipment (UE) may be configured to relay transmissions to second user equipment upon reception of a negative acknowledgment (NACK) from the second user equipment. In other systems, one or more UEs may be configured to receive transmissions relayed from other UEs in response to a NACK.

    Abstract: A first user equipment (UE) is configured to communicate with a second UE in sidelink communications using a sidelink configured grant (CG) configured by a base station. The first UE receives, a radio resource control (RRC) message or physical layer signaling including a sidelink configured grant (CG) configuration indicating at least some parameters configured by a base station for sidelink communications between the first UE and a second UE. The first UE transmits or receives a transport block for the sidelink communications on a physical sidelink shared channel (PSSCH) based on the at least some parameters.

    Abstract: This disclosure provides systems, methods, and apparatuses for jointly activating or releasing a plurality of semi-persistent scheduling (SPS) configurations using a single downlink control information (DCI) message. In some implementations, a user equipment (UE) receiving the DCI message can determine, for each SPS configuration, a number of time slots between an end of the received DCI message and a beginning of one or more downlink (DL) data frames based on a first value contained in the DCI message. The UE can also determine, for each SPS configuration, a number of time slots between an end of the DL data frames and an instance in time at which the UE is to transmit a hybrid automatic repeat request acknowledgement (HARQ-ACK) based on a second value contained in the DCI message. In some instances, the single DCI message can also jointly activate or release a plurality of configured grant (CG) configurations.
