A method of receiving, by a terminal according to one embodiment of the disclosure, a physical downlink shared channel (PDSCH) in a wireless communication system includes receiving downlink control information (DCI) for scheduling the PDSCH, and receiving the PDSCH based on the DCI. The PDSCH is related to a code word generated based on a polar code.

The application discloses a method for improving resistance to wheat scab QFhb-2DL and QFhb- 3BL The application discloses a method for improving resistance to wheat scab, a molecular marker, a primer, the molecular marker comprising a dCAPS marker of QFhb-2DL and / or a KASP marker of QFhb-3BL . The application first develops a molecular marker closely linked to QFhb-2DL and a molecular marker closely linked to QFhb-3BL . Under the premise of stabilizing the resistance to stripe rust, dwarf, large spike and multiple spike characteristics of a wheat variety in the upper reaches of the Yangtze River, the application realizes molecular design breeding by using the developed new marker closely linked to the locus, and quickly introduces the disease-resistant genotypes of QFhb-2DL and QFhb-3BL into the wheat variety in the upper reaches of the Yangtze River, breeds a strain which is resistant to scab and has a yield significantly higher than that of a control, and realizes a breakthrough in the resistance to scab in the upper reaches of the Yangtze River.

The invention relates to the technical field of obstetrical medicine cabinet information interaction, and particularly discloses an obstetrical medicine cabinet information interaction method and system based on multimode communication decision, and the method comprises the steps: analyzing the business semantics of obstetrical medicine cabinet operation data, generating a business data package with a dynamic aging weight, and employing a multimode channel quality evaluation module to evaluate the operation data of an obstetrical medicine cabinet. Integrating indexes such as signal strength, packet loss rate and time delay to generate a multimode channel quality vector; the system further couples the service emergency degree and the channel quality, generates a target routing strategy, and realizes differentiated data transmission; in link transmission control, double-link concurrent redundancy transmission and local cache delay transmission are supported, and key information is ensured to be transmitted preferentially; in addition, the system also has an emergency broadcast mechanism, and when the whole link is interrupted and the service is emergency, the key information is broadcasted through the low-power-consumption Bluetooth, so that the information accessibility under the extreme condition is enhanced; the stability and reliability of information interaction of the obstetrical medicine cabinet are improved.

The present application relates to the technical field of wireless communication, in particular to a wireless channel measurement time slot scheduling method under multi-wearable device concurrency. The present application periodically acquires the state and distance information of the intelligent wearable device through the base station, dynamically allocates the measurement priority, and determines the total measurement time slot quantity according to the priority. Time slot allocation is adopted, combined with the priority polling mechanism, to allocate non-overlapping AoA / CS measurement time slots for each device, and the starting time and duration are issued through the wireless control channel to guide the device to transmit the measurement signal in the corresponding time slot. The present application solves the wireless channel measurement conflict problem when multiple nodes concurrently access, and through orthogonal allocation and dynamic resource configuration, the balance between high-precision spatial perception and low-power consumption of small-sized wearable devices is considered while reducing the air interface signal collision.

The present invention relates to a method, device and system for uplink transmission and downlink reception in a wireless communication system. The present invention relates to a method for transmission and reception of a radio signal by a terminal in a wireless communication system. According to the present specification, a method is disclosed, comprising the steps of determining whether transmission of an uplink radio signal assigned to a terminal or reception of a downlink radio signal is possible on a time slot configured to include at least one of one or more downlink symbols for downlink transmission, one or more flexible symbols, and one or more uplink symbols for uplink transmission; and controlling the transmission of the uplink radio signal or the reception of the downlink radio signal based on the determination. According to the present invention, even if the configuration of the time slot is changed, the terminal can transmit the uplink radio signal, and thus uplink radio signal transmission omission or unnecessary retransmission of the uplink radio signal can be prevented. And by defining the valid timing of the uplink signal such as a physical random access channel, the frequency efficiency of the network can be increased and the energy consumption of the terminal can be reduced.
