The present specification provides a method for transmitting a transport block (TB) by using downlink control information (DCI) in a wireless communication system. In particular, the method, performed by a terminal, comprises: receiving first DCI from a base station; selecting a modulation and coding scheme (MCS) table, on the basis of the first DCI; calculating a first transport block size (TBS), on the basis of at least one of a format of the first DCI and the selected MCS table; and transmitting, to the base station, a first TB according to the calculated first TBS, wherein the first TBS is the same as a second TBS of a second TB transmitted before the transmission of the first TB.

There are provided measures for time slot control for radio power boosting. Such measures exemplarily comprise transmitting, to a terminal, a configuration indicative of uplink slots to be used by said terminal when a first modulation and coding scheme is activated, and controlling a transmission, to said terminal, of information indicative of that said first modulation and coding scheme is to be activated.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). An embodiment of the present disclosure provides a base station, a user equipment (UE), and a method for uplink resource allocation and a method for uplink transmission, which are applied in the field of communication technologies. The method includes that: a base station allocates Bandwidth Part (BWP) resources and intra-BWP Physical Resource Block (PRB) resources to a UE, and then transmits BWP resource indication information and intra-BWP PRB resource indication information to the UE. The BWP resource indication information is used for indicating the BWP resources allocated by the base station to the UE. The intra-BWP PRB resource indication information is used for indicating the intra-BWP PRB resources allocated by the base station, and then the UE receives the BWP resource indication information and the intra-BWP PRB resource indication information transmitted by the base station, and then determines the BWP resources and the intra-BWP PRB resources allocated by the base station according to the BWP resource indication information and the intra-BWP PRB resource indication information so as to perform uplink transmission.

The present disclosure provides a method for indicating a modulation and coding scheme (MCS), including a step of when it is determined that a UE supports a downlink 256QAM mode, indicating the 256QAM mode using current information indicating the MCS or extended information indicating the MCS in downlink control information (DCI). The present disclosure further provides a method for receiving downlink data, including a step of, after a UE has received information indicating an MCS which includes indication information indicating a 256QAM mode, receiving the downlink data according to the 256QAM mode and a corresponding TBS index. The present disclosure further provides devices for implementing the above methods.

A wireless device receives a downlink control information (DCI) indicating uplink resources in m subframes of a licensed assisted access (LAA) cell. The DCI comprises: a resource blocks (RBs) field; a modulation and coding scheme (MCS) field; and a redundancy versions (RV) field and a new data indicators (NDI) field for each of the m subframes. The wireless device transmits, in each of the m subframes, one or more transport blocks employing the RBs field and the MCS field across the m subframes and employing each RV field and each NDI field corresponding to each subframe.

A wireless device receives a radio resource control (RRC) message comprising an aperiodic sounding reference signal (SRS) subframe parameter. The wireless device receives a downlink control information (DCI) triggering an SRS transmission and indicating uplink resources in one or more subframes. The wireless device determines a position of a subframe in the one or more subframes based, at least in part, on the aperiodic SRS subframe parameter. The wireless device transmits the SRS in the subframe.

Provided is a communication device, which is enabled to improve the throughput of a communication system by reducing the difference of a transmission power between an SCCH and an SDCH thereby to satisfy the required quality of a PAPR. In this device, an MCS selection unit (111) of a transmission unit (110) decides, with reference to a CQI lookup table, an MCS pattern (MCS1) of the SDCH, an MCS pattern (MCS2) of the SCCH and information (multiplex information) on multiplex positions on the time axes of those two channels, on the basis of the CQI information. On the basis of the MCS2 and the MCS1, encoding modulation units (112 and 113) perform encoding and modulating operations. According to the multiplex information, a channel multiplexing unit (114) time-division multiplexes the SCCH and the SDCH thereby to generate a transmission signal.

A shared control channel structure includes at least one control channel to be allocated at least to a user for at least one of uplink and downlink directions in a network, which the at least one control channel is arranged as at least a part of a modular structure comprising of modular code blocks on at least two different sizes. One of such modular structures may be represented as a tree structure in particular, where each of the modular code blocks define one node of the tree, respectively.

A method for transmitting control information, a channel or signal, and a corresponding sending end are provided. The method includes: after performing low bit rate coding and/or low order modulation on data containing the control information, carrying the data on partial physical resources of a reference signal for transmission, herein the coding rate is lower than the highest coding rate set by the system and the modulation order is lower than the highest modulation order set by the system. The method further includes: selecting one transmission mode from multiple transmission modes configured for the channel or signal; transmitting known data; transmitting non-known data and being subject to a coding limitation and/or modulation limitation; and transmitting the non-known data and not being subject to the modulation limitation and the coding limitation; and sending transmission mode configuration information to a receiving end to indicate the selected transmission mode.

Provided are a data transmitting or receiving method and device for dual Transport Blocks (TBs), a transmitter and a receiver. Data to be transmitted is divided into two portions, where transport blocks TB1 and TB2 are generated respectively according to a corresponding predetermined Modulation Coding Scheme (MCS) for each portion. The TB1 is modulated into an amplitude weighted complex symbol sequence S1, and the TB2 is modulated into an amplitude weighted complex symbol sequence S2. The S1 and the S2 are superposed to generate a complex symbol sequence S3 corresponding to a new TB, where the complex symbol sequence S3 corresponding to the new TB possesses Gray properties. The new TB is transmitted to a receiver.
