The present disclosure relates to a network node having a processor and a transceiver. The processor is configured to select at least one user device if a Channel Estimation Timer (CET) for a radio channel between the network node and the at least one user device is valid, and to schedule data transmission to the at least one selected user device. The transceiver is configured to perform the scheduled data transmission to the at least one selected user device. The present disclosure also describes a corresponding method, a wireless communication system including such a network node, a computer program, and a computer program product.

A data reception device comprises: a first data input for receiving a first data signal and a clock input for receiving a clock signal; and a stability detection circuit adapted to generate: a first error signal indicating when a data transition of the first data signal occurs during a first period at least partially before a first significant clock edge of the clock signal; and a second error signal indicating when a data transition of the first data signal occurs during a second period at least partially after the first significant clock edge of the clock signal; and a control circuit configured to generate a control signal for adjusting the sampling time of the first data signal based on said first and second error signals.

A wireless device receives a radio resource control (RRC) message that includes configuration parameters for scheduling a plurality of physical uplink shared channels (PUSCHs) via a downlink control information (DCI). In an embodiment, the configuration parameters may include an indication enabling a dynamic determination of a PUSCH of the plurality of PUSCHs for multiplexing an uplink control information (UCI). In an additional embodiment, the UCI may overlap with a first PUSCH of the plurality of PUSCHs. The wireless device may transmit the UCI via a second PUSCH of the plurality of PUSCHs in response to a failed listen-before-talk (LBT) procedure for the first PUSCH.

A communication method includes a first terminal device that determines first configuration information of first discontinuous reception DRX, where the first DRX controls the first terminal device to receive data on a sidelink. The first terminal device sends the first configuration information to a second terminal device, where the second terminal device is a terminal device that establishes a sidelink connection to the first terminal device. This can reduce power consumption of the terminal device.

This disclosure provides systems, methods, and apparatus for link adaptation in a wireless local area network (WLAN). A link adaptation test packet from a first WLAN device to a second WLAN device may be formatted as a multiple-input-multiple-output (MIMO) transmission and may include one or more test portions for link quality estimation of the MIMO transmission. A link quality estimation portion of the test packet may permit measurement of link quality for various spatial streams of the MIMO transmission. The link adaptation test packet may enable a fast rate adaptation of a communication link based on the impact of interference to the various spatial streams. The second WLAN device may provide feedback information regarding the one or more test portions. The feedback information may be used to determine a transmission rate for a subsequent transmission from the first WLAN device to the second WLAN device based on wireless channel conditions.

A method by a user equipment (UE) is described. The method includes receiving, from a base station, a first radio resource control (RRC) parameter including a first list of one or more CSI trigger states, a second RRC parameter indicating a first total number of bits N_TS1 for a first CSI request field of a first DCI format, a third RRC parameter including a second list of one or more CSI trigger states, and a fourth RRC parameter indicating a second total number of bits N_TS2 for a second CSI request field of a second DCI format, determining a CSI trigger state in response to a CSI request field of a DCI format, wherein in a first case that a total number of the one or more CSI trigger states within the first list is greater than 2.sup.N_TS11, the processing circuitry is further configured to select one or more of the CSI trigger states out of the first list which are mapped to one or more codepoints of the first CSI request field of the first DCI format, in a second case that a total number of the one or more CSI trigger states within the second list is greater than 2.sup.N_TS2−1, the processing circuitry is further configured to select one or more of the CSI trigger states out of the second list which are mapped to one or more codepoints of the second CSI request field of the second DCI format.

Certain aspects of the present disclosure provide techniques for channel state information (CSI) reporting based on user equipment (UE) parameters. A method that may be performed by a UE includes receiving a configuration to report aperiodic CSI. The method generally includes determining, based on one or more parameters, to send a first report including hybrid automatic repeat request (HARQ) feedback and not CSI feedback or a second report including HARQ feedback and CSI feedback. The method generally includes sending the first report or the second report based on the determination.

A technique includes receiving a plurality of synchronization signal blocks, including synchronization signals and beam specific reference signals, receiving a plurality of beam sweeping scheduling blocks, each beam sweeping scheduling block corresponding to one of the synchronization signal blocks and including scheduling information to schedule a dynamic size beam sweeping resource (e.g., mini-slot or other resource) for transmission of common control information (e.g., paging data and/or system information or SIB) via a set of one or more beams, and selecting, based on a measurement of signals of at least one of the synchronization signal blocks and the scheduling information, one of the dynamic size beam sweeping resources (e.g., one of the beam sweeping mini-slots or other resource) to receive the common control information (e.g., paging data and/or system information or SIB).

A terminal apparatus includes a transmitter configured to transmit, in a case that the aperiodic channel state information reporting and the periodic channel state information reporting occur in a same time period for a certain cell group, only an aperiodic channel state information report in the same time period, transmit, in a case that the semi-persistent channel state information reporting and the aperiodic channel state information reporting occur in a same time period for a certain cell group, only the aperiodic channel state information report in the same time period, and transmit, in a case that the periodic channel state information reporting and the semi-persistent channel state information reporting occur in a same time period for a certain cell group, only a semi-persistent channel state information report in the same time duration.

An information transmission method includes: receiving, by a terminal, a first downlink control information (DCI) used for scheduling the terminal to transmit uplink data through a physical uplink shared channel (PUSCH) in a target time unit; receiving, by the terminal, a second DCI, feedback response information of the second DCI being transmitted in the target time unit, and a time interval between a transmission time of the second DCI and a starting position of the PUSCH being not less than a preset time interval; determining a number of encoded bits of the uplink data scheduled by the first DCI according to a number of bits of the feedback response information of the second DCI; and transmitting, by the terminal according to the number of encoded bits, the uplink data and the feedback response information of the second DCI through the PUSCH in the target time unit.
