A communications method includes: A control node determines first configuration information, where the first configuration information belongs to a configuration information set, the configuration information set includes at least one piece of configuration information, and the first configuration information is used to indicate whether a first slave node performs, in some or all of time units included in a preset time period, an operation corresponding to the first configuration information. This is applicable to coordination and management of communication between slave nodes in a transmission system having a plurality of service requirements, and implements flexible configuration of each slave node in the transmission system by the control node.

A user equipment maps a high priority hybrid automatic repeat request-acknowledgment/negative acknowledgment (HARQ-ACK/NACK) information to one or more resource elements (REs), and maps one or more of a low priority HARQ-ACK/NACK information, channel state information (CSI), or uplink-shared channel (UL-SCH) data to REs while rate matching around the mapped high priority HARQ-ACK/NACK REs. A network entity receives an uplink transmission, including high and low priority HARQ-ACK/NACK information, CSI, and UL-SCH data mapped to high and low priority HARQ-ACK/NACK REs, CSI REs. and UL-SCH REs, respectively. The low priority HARQ-ACK/NACK REs, the CSI REs, and the UL-SCH REs are rate matched around the high priority HARQ-ACK/N ACK REs. The network entity demaps and decodes the REs of the high and low priority HARQ-ACK/NACK, the CSI, and UL-SCH to obtain the high and low priority HARQ-ACK/NACK information, CSI, and UL-SCH data.

A method of operating a terminal device for transmitting a first amount of data, the method comprising receiving an indication of an allocation of communications resources, the allocated communications resources sufficient for transmitting a second amount of data, the second amount of data greater than or equal to the first amount of the data, selecting from a plurality of permitted TBS values a transport block size, TBS, for the transmission of the first amount of data, based on the first amount, determining communications resources for transmitting the first amount of the data based on the selected TBS and the allocated communications resources, and transmitting the first amount of the data using the determined communications resources.

Provided are a CQI feedback enhancement method, a CQI feedback enhancement device, a CQI feedback enhancement system, a UE and a base station. The CQI feedback enhancement method includes: a base station sends downlink traffic data to a UE; the UE decodes the downlink traffic data; first information is sent to the base station in a case where an error result is obtained by decoding the downlink traffic data, where the first information includes an NACK instruction and an aperiodic CQI, or the first information includes one NACK state of multiple NACK states and different NACK states correspond to different CQIs; and the base station receives the first information.

A user terminal according to one aspect of the present disclosure includes: a transmitting/receiving section that performs transmission and reception by using a first Component Carrier (CC) that uses a first Sub-Carrier Spacing (SCS), and a second CC that uses a second SCS larger than the first SCS; and a control section that, when a semi-static Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK) codebook related to both of the first CC and the second CC is transmitted on an uplink shared channel of the second CC, deletes an HARQ-ACK bit corresponding to a downlink shared channel candidate that does not satisfy a requirement of processing time. According to one aspect of the present disclosure, it is possible to appropriately transmit HARQ-ACK even when a semi-static HARQ-ACK codebook is configured.

User equipment may request to communicate with a basestation over a contention-based wireless communication channel. The basestation and the user equipment may perform a multiple-step random access protocol to determine whether the user equipment may communicate over the wireless communication channel. The architecture, e.g., the fields and structure of the messages sent by the basestation may indicate the content and type of those same messages.

In an 802.11be wireless system, data units are generated for transmission by configuring a transmitting device to process encoding parameters, including a first encoding parameter N.sub.SD and a second encoding parameter N.sub.SD,short, to select a padding boundary from pre-defined padding boundaries in the last symbol that will most closely include the number of information bits N.sub.EXCESS in the last symbol and to append padding bits to the number of information bits N.sub.EXCESS to fill up to the selected padding boundary in the last symbol, thereby generating pre-encoded data bits which are encoded for data transmission, where at least the first encoding parameter N.sub.SD is specified for an aggregated resource unit size that is allowed under the 802.11be protocol as a sum of N.sub.SD values for at two other resource units.

Proposed is a method and device for receiving data in a wireless LAN system. Specifically, an AP transmits a trigger frame to a first to a third station (STA) through a multi-band. The AP receives data from the first to third STAs on the basis of the trigger frame. In the multi-band, a first band to a third band are combined. The trigger frame includes a common information field and a first to a third user information field. When the first and second STAs are associated with the first band, the first user information field includes user information relating to the first and second STAs. When the second and third STAs are associated with the second band, the second user information field includes user information relating to the second and third STAs. When the third STA is associated with the third band, the third user information field includes user information relating to the third STA.

Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as long term evolution (LTE). Disclosed is a method by which a terminal transmits a buffer status report (BSR) in a communication system, including allocating an uplink resource from a base station; comparing the number of padding bits with a value obtained by summing the size of the BSR and the size of a sub-header of the BSR; and transmitting, to the base station according to the comparison result, the BSR including information indicating the presence or absence of a field representing a buffer size for at least one logical channel group (LCG).

A method and a device for transmitting an A-PPDU in a wireless LAN system are proposed. Specifically, a transmission STA generates an A-PPDU and transmits the A-PPDU to a reception STA. A first PPDU and a second PPDU are aggregated into the A-PPDU. The first PPDU includes an L-Header field, a first EDMG-Header field, and a first data field. The second PPDU includes a second EDMG-Header field and a second data field. Zero padding is inserted in the first data field on the basis of the minimum number of symbol blocks of the first PPDU.
