Method and apparatus in node for wireless communication

Abstract

The invention discloses a method and an apparatus in a node for wireless communication. A node receives a first synchronization signal and a first broadcast signal, wherein the first broadcast signal carries a target index; a first synchronization signal occupies a first time-frequency resource set, a second time-frequency resource set is occupied by the first broadcast signal, and the target time-frequency resource subset and the first time-frequency resource set comprise the same symbol in a time domain; the type of the first node device is used for determining whether the target time-frequency resource subset is occupied by the first broadcast signal; the subcarrier interval of subcarriers included by the first time-frequency resource set in a frequency domain is equal to a first subcarrier interval, and the first time-frequency resource set is used for determining the first subcarrier interval in a frequency band to which the frequency domain belongs; the target index determines whether the first broadcast signal carries a first information block, and the first information block determines a control resource set. According to the invention, broadcast channel 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...
