Abstract

The invention discloses a method and an apparatus in a node for wireless communication. The node receives the first signaling and receives the first signal or sends the first signal; the first signal is used for determining a virtual frequency domain resource set, the first signal occupies a target frequency domain resource set in a frequency domain, and the target frequency domain resource set comprises a positive integer number of frequency domain resource blocks; virtual frequency domain resource blocks included in the virtual frequency domain resource set are mapped to frequency domain resource blocks included in the target frequency domain resource set one by one according to a first mapping mode; the number of virtual frequency domain resource blocks included in the virtual frequency domain resource set is not greater than a first threshold value; any frequency domain resource block included in the target frequency domain resource set belongs to a first resource pool; the size relation between the first threshold value and the number of the frequency domain resource blocks included in the first resource pool is used for determining the first mapping mode. The transmission performance is improved.

Description

technical field [0001] The present application relates to a transmission method and device in a wireless communication system, and in particular to a transmission scheme and device for a device with reduced capability in wireless communication. Background technique [0002] The application scenarios of future wireless communication systems are becoming more and more diversified, and different application scenarios put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the new air interface technology (NR, New Radio) (or 5G) research, passed the WI (Work Item, work item) of the new air interface technology (NR, New Radio) at the 3GPP RAN#75 plenary meeting, and started to standardize NR. [0003] In the new air interface technology, IoT applications are an important part. Although some new features have been introduced in Version 15 (Release 15) and Version 16 (Release 16) to s...
