Abstract: Systems, methods, apparatuses, and computer program products for cyclic prefix (CP) extension and listen before talk (LBT) type for uplink transmissions. Specifically, certain embodiments may provide for applying a CP and/or an LBT when downlink control information (DCI) schedules two discontinuous uplink transmissions. For example, certain embodiments may provide for determining the LBT type and CP extension for jointly scheduled aperiodic sounding reference signal and physical uplink shared channel/physical uplink control channel transmissions. When the two or more transmissions are non-consecutive, the first one of the transmissions may apply the CP extension and the LBT type indicated by the scheduling DCI. For the second transmission, the CP extension may depend on the CP extension indicated in the DCI.

Abstract: Various communication systems may benefit from a reduction in latency. For example, communication systems may benefit from an improved transmission of an uplink reference signal in an uplink channel. A method, in certain embodiments, includes determining by a user equipment a candidate location of a transmission of an uplink reference signal in a channel. The method also includes determining by the user equipment a triggering window associated with the candidate location of the transmission of the uplink reference signal in the channel. In addition, the method includes receiving an uplink grant for a data transmission from a base station. Further, the method includes transmitting the uplink reference signal based on the uplink grant being at least partially within the triggering window.

Abstract: Various communication systems may benefit from appropriate coordination of measurements for mobility or other reasons. For example, Long Term Evolution communication systems may benefit from signaling for uplink short transmission time interval transmissions. A method can include determining how a user equipment is to transmit with respect to a demodulation reference signal. The method can also include providing uplink grant to schedule the user equipment to transmit according to the determination.

Abstract: Various communication systems may benefit from an improved resource block group allocation in a cell. A method may include determining at a network entity a common frequency resource allocation grid in a cell. The method may also include configuring at the network entity a frequency location of a bandwidth part of a user equipment within the cell. The frequency location of the bandwidth part may be offset from a reference point of the common frequency resource allocation grid. In addition, the method may include determining a size of one or more of a plurality of resource block groups within the bandwidth part of the user equipment based on the frequency location of the bandwidth part and the reference point. Further, the method may include transmit downlink control information from the network entity to the user equipment.

Abstract: Solutions for determining a resource for transmitting/detecting an uplink (UL) control signal are proposed. For example, a method includes receiving a physical resource configuration and/or an assigned resource indicator for transmitting the UL control signal, wherein the physical resource configuration indicates a plurality of resources in frequency domain. The method also includes determining a resource based on the received physical resource configuration and/or the assigned resource indicator; and adjusting the determined resource for transmitting the UL control signal based on at least one of an outcome of downlink (DL) listen before talk (LBT) performed prior to the transmission of the UL control signal, an outcome of UL LBT performed prior to the transmission of the UL control signal, and a time gap between the UL LBT and the transmission of the UL control signal.

Abstract: Example embodiments of the present disclosure relate to a device, method, apparatus and computer readable storage medium for scheduling serving cells with a signaling message. In example embodiments, a terminal device receives, in a Layer 1 (L1) signaling message, a resource indication to schedule resources on a plurality of bandwidth parts in a plurality of serving cells. The terminal device determines a reference size of a reference bandwidth part. The terminal device determines a reference resource based on the received resource indication and the reference size of the reference bandwidth part. The terminal device further determines alignment between the reference bandwidth part and a scheduled bandwidth part of the plurality of bandwidth parts. The terminal device determines, based on the reference resource and the alignment, a scheduled resource on the scheduled bandwidth part.
