  • Patent number: 11516837
    Abstract: Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated to base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.

  • Publication number: 20220302967
    Abstract: The present disclosure relates to radio network communication. In one of its aspects, the present disclosure relates to a method, performed by a first APU, for sequential transmit precoding in a radio stripe system. The system comprises at least two APUs connected 5 in series from a CPU and serves at least two UEs. According to the method, channel estimates for channels to the served UEs are obtained and based on these, a precoding filter is determined. The precoding filter is going to be applied to signals that are to be transmitted from the first APU to the UEs. Thereafter, based on the determined precoding filter and the obtained channel estimates, effective precoded channels for the 0 signals to the UEs are determined. These represent the effective channel created after the precoding filter being applied to each channel for the UEs. The effective precoded channels are transmitted to at least one subsequent second APU. To be published with FIG.

  • Publication number: 20220302838
    Abstract: A switched mode power supply, SMPS, which supplies an output voltage to a load, wherein a load current drawn by the load varies over time in accordance with load scheduling information. The SMPS comprises a voltage conversion circuit which converts an input voltage of the SMPS to the output voltage, and a controller which generates a control signal (SSW) based on a feedback signal indicative of the output voltage, and controls the voltage conversion circuit using the control signal to regulate the output voltage. The controller further generates a modified control signal (S?SW) using an indication of a change in the load current that is based on the load scheduling information, and controls the voltage conversion circuit using the modified control signal before the change in the load current occurs to suppress a voltage transient in the output voltage caused by the load current change.

  • Publication number: 20220272641
    Abstract: A user equipment receives a signal indicating a time schedule for intermittent transmission of information from a base station managing a cell. The intermittent transmission of information enables the UE to perform mobility measurements when the cell is in a discontinuous transmission (DTX) mode and the UE is an active terminal not served by the cell. The UE performs, based on the intermittent transmission of information, a mobility measurement when the cell is in the DTX mode and reports the mobility measurement to the base station.

  • Publication number: 20220240169
    Abstract: A radio node (12) is configured for use in a wireless communication system (10) in which system information is transmitted in parts. The radio node (12) in this regard generates explicit signaling that is associated with a first part (16) of system information and that indicates a sequence (24) with which a second part (20) of system information is to be demodulated or descrambled. The radio node (12) transmits the explicit signaling over a signaling channel (25). Correspondingly, a wireless communication device (14) receives system information for the system (10) in parts. The device (14) receives the first part (16) over the first channel (18). The device (14) also receives the explicit signaling over the signaling channel (25). The device (14) further receives the second part (20) over the second channel (22), by demodulating or descrambling the second part (20) using the sequence (24) indicated by the explicit signaling.
