摘要： The present invention relates to a method for an NR (New Radio Access Technology) user equipment to transmit and receive a signal in a wireless communication system and an apparatus therefor. The method comprises the steps of checking a PDCCH (Physical Downlink Control Channel) order and, if the PDCCH order is checked, initiating a random access procedure. In this case, if a first uplink carrier and a second uplink carrier are configured, the random access procedure is configured to transmit a random access preamble via a specific uplink carrier corresponding to an indicator associated with the PDCCH order among the first uplink carrier and the second uplink carrier.

摘要： One disclosure of the present specification provides a method for, by a wireless device, determining a transport block size (TBS). The method comprises the steps of: determining the number of resource elements (REs) in a slot; calculating a value associated with a TBS on the basis of the determined number of REs and a coding rate; comparing the calculated value with a predetermined threshold value; and determining the TBS according to the comparison. When the calculated value is less than or equal to the predetermined threshold value, the TBS may be determined by using a predetermined table.

摘要： A method and apparatus for allocating resources for a machine type communication user equipment (MTC UE) in a wireless communication system is provided. A base station indicates a transport block size (TBS) directly, adapts a code rate according to repetition numbers across multiple subframes in a MTC physical downlink shared channel (M-PDSCH) for the MTC UE, and allocates resources for the M-PDSCH by using the indicated transport block size and the adapted code rate. The TBS may be determined based on a modulation and coding scheme (MCS) only.
