Abstract: Various features related to design and implementation of a single slot sPUCCH are described. In an aspect, the single slot sPUCCH supports intra-sTTI frequency hopping. In some configurations where intra slot frequency hopping is supported, one or two hops per slot may be utilized. An apparatus, e.g., a UE, may be configured to transmit first UCI in a first set of resources within a first set of symbols of a sPUCCH within a slot, and transmit second UCI in a second set of resources within a second set of symbols of the sPUCCH within the slot, where the second set of symbols may be subsequent to the first set of symbols. In some configurations, a number of symbols in each of the first and second sets of symbols maybe based on whether the slot is a first slot of a subframe or a second slot of the subframe.

Abstract: In enhanced licensed assisted access (eLAA), providing several approaches to report the CSI measurement may be desirable to provide flexibility in CSI reporting, especially in aperiodic CSI reporting. Further, a difference in using a licensed carrier and an unlicensed carrier may be considered during communication. In addition, assigning different transmit power usage based on different transmission types may be desired. The apparatus may be a user equipment (UE). The apparatus may be a UE. The UE receives a grant for uplink communication. The UE determines a reporting subframe based on the grant. The UE determines whether to select, as a reference subframe, a triggering subframe in which the grant is received or a subframe before the reporting subframe. The UE transmits, in the reporting subframe, channel state information (CSI) measured in the reference subframe.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. A base station transmits a provisional grant uplink assignment to a set of UEs. When a UE receives the provisional grant uplink assignment, the UE performs a clear channel assessment (CCA) operation on a secondary component carrier (SCC) based on the provisional grant UL assignment, the SCC being a contention-based carrier. Then, the UE transmits a schedule request (SR) on the SCC when the CCA operation succeeds. The base station transmits grant confirmation(s) on the SCC in response to the detected SR(s). Once the UE receives a grant confirmation on the SCC in response to the SR, the UE transmits data on the SCC.

Abstract: The present disclosure relates to reducing control overhead in a wireless communication system. For example, a network entity may determine to transmit data according to a codeword format based on at least one of a transmission time interval (TTI), or a traffic type of the data, or any combination thereof, and configure the data for transmission on a communication channel according to the codeword format. Further, for instance, a user equipment may receive a transmission from a network entity on a downlink communication channel according to a codeword format, and transmit at least one of an acknowledgement (ACK) or a negative acknowledgement (NACK) on an uplink communication channel in response to receiving the transmission from the network entity.
