In a method for transmitting uplink control information using a physical uplink shared channel (PUSCH) in a wireless communication system, the method is performed by a terminal and includes receiving downlink control information including an accumulated number of physical downlink shared channels (PDSCH) transmissions associated with a cell group configured for the terminal, coding the uplink control information using the accumulated number of PDSCH transmissions, and transmitting the coded uplink control information using the PUSCH.

A method and an apparatus for uplink transmission in a communication system. An operation method of a terminal includes: receiving, from a base station, first SFI information indicating n flexible symbol(s); receiving, from the base station, second SFI information re-indicating m symbol(s) of the n flexible symbol(s) as uplink (UL) symbol(s); and transmitting an SRS to the base station through the m symbol(s) re-indicated as a UL symbol among the n flexible symbol(s) indicated as a flexible symbol. Therefore, performance of the communication system can be improved.

A method and a device for transmitting and receiving a PPDU on the basis of an FDD in a wireless LAN system are presented. Particularly, an AP transmits a trigger frame to a first STA and a second STA. The AP transmits a first downlink (DL) PPDU to the first STA on the basis of the trigger frame. The AP transmits a second DL PPDU to the second STA on the basis of the trigger frame. The AP receives a first uplink (UL) PPDU from the second STA on the basis of the trigger frame. The trigger frame includes bandwidth information of a primary channel and a secondary channel. The first DL PPDU is transmitted through the primary channel. The second DL PPDU and the first UL PPDU are transmitted through the secondary channel. The first and second DL PPDU are simultaneously transmitted. The first UL PPDU is received after a preset period after the second DL PPDU is transmitted.

The present invention relates to a wireless communication terminal and a wireless communication method for efficiently managing simultaneous data transmissions of a plurality of terminals. To this end, provided are a base wireless communication terminal including: a transceiver configured to transmit and receive a wireless signal; and a processor configured to control an operation of the base wireless communication terminal, wherein the processor is configured to: transmit a trigger frame triggering a multi-user uplink transmission of a plurality of terminals, receive multi-user uplink data through resources allocated to the plurality of terminals, and transmit a block ACK through the resources in response to the received multi-user uplink data, wherein the transmission of the block ACK in each resource is terminated at the same time, and a wireless communication method using the same.

A wireless device receives a first downlink control information (DCI) indicating a non-numerical value for a transmission of a feedback. The wireless device may also receive a second DCI indicating a slot offset indicating a slot for a physical uplink shared channel (PUSCH) and a first beta-offset value for multiplexing control information in the PUSCH. In response to the first beta-offset value being equal to or greater than a threshold, the wireless device may transmit the feedback via the PUSCH during the slot.

Communication devices are provided that facilitate receiving information units and providing feedback to other communication devices.

Methods and apparatus for wireless communication are provided. In aspects, a method of wireless communication is provided, including scheduling ultra-reliable and low-latency communications (URLLC) communication in a first set of one or more portions of a self-contained wireless communication structure having a plurality of portions, and adjusting one or more (e.g., remaining) portions of the self-contained wireless communication structure subsequent the first set of one or more portions based on the scheduling. In aspects, the method further includes transmitting an indicator of the adjusting to one or more user equipments. Numerous other aspects are provided.

Provided are an information transmission and receiving method and device, a storage medium and an electronic apparatus. The information transmission method includes: transmitting at least two pieces of the following information in a multiplexing manner on a physical channel: channel state information (CSI), first control information or data information. The first control information includes at least one of: hybrid automatic retransmission request acknowledgement (HARQ-ACK) information or scheduling request (SR) information.
