Abstract: A method, apparatus, and computer readable medium facilitate network control by allowing a base station to predict when power class fallback will occur in user equipment. In the context of a method, the method receives a message comprising information about at least one of a first power class or a maximum duty cycle associated with user equipment. The method determines, based on at least the first power class or the maximum duty cycle, a threshold duty cycle for the user equipment. The method causes the threshold duty cycle to be transmitted to the user equipment. The method determines an uplink transmission schedule for the user equipment based at least on the first power class or the maximum duty cycle. The method receives, from the user equipment, a report that the threshold duty cycle has been exceeded by the user equipment.

Abstract: According to an example aspect of the present disclosure, there is provided a method comprising receiving a configuration with a first periodicity for at least one of a physical uplink control channel for reporting channel state information or a transmitting of a sounding reference signal, and determining whether to stop or pause at least one of the reporting of the channel state information or the transmitting of the sounding reference signal based on at least one of receiving a command to stop or pause the reporting of the channel state information or the transmitting of the sounding reference signal or determining that at least one second periodicity is active for performing the reporting of the channel state information or the transmitting of the sounding reference signal.

Abstract: Systems, methods, apparatuses, and computer program products for channel access for semi-static uplink (UL) resources are provided. One method may include receiving, at a user equipment, an indication of at least one of time portions of channel occupancy time (COT) where the user equipment can use a first type of channel access for configured uplink (CUL) transmission or time portions where a second type of channel access is required prior to the configured uplink (CUL) transmission. The method may then include, based on the received indication, determining a channel access mechanism to use when transmitting on a configured uplink (CUL) resource.

Abstract: An example method includes determining at least a first search space configuration and a second search space configuration; determining a first set of periodic search spans formed by a first subset of time-domain symbols of each search window in the first set of periodic search windows and further determining a second set of periodic search spans; forming a sequence of search spans from the first set of periodic search spans and the second set of periodic search spans and determining a virtual search window; determining a maximum number of downlink control information candidates; searching the received signal within the virtual search window for up to the maximum number of downlink control channel candidates and omitting the searching for remaining downlink control channel candidates and, upon detecting the downlink control channel, extracting downlink control information on the downlink control channel.

Abstract: Various example embodiments may relate to punctured transmission of data within synchronization signal blocks. An apparatus may obtain data for transmission on a data channel of a synchronization signal block of a transmission frame and allocate the data to resource elements of the data channel. The allocation of the data may be dependent on the frame number of the transmission frame. The apparatus may further puncture one or more resource elements at edge(s) of the synchronization signal block and transmit the synchronization signal block. Another apparatus may receive the synchronization signal block and decode the data. Apparatuses, methods, and computer programs are disclosed.
