Description

User equipment, method and device in base station used for wireless communication Technical field

The present application relates to a transmission method and apparatus in a wireless communication system, and more particularly to a method and apparatus for data channel transmission when a 5G and a narrowband Internet of Things system coexist.

Background technique

The NB-IoT-Narrow Band Internet of Things is an emerging technology in the IoT field. NB-IoT is built on a cellular network and consumes only about 180KHz of bandwidth. It can be deployed directly in traditional networks to reduce deployment costs. Smooth upgrades; they can also be deployed independently. At present, the deployment modes of NB-IoT mainly include Standalone mode, LTE guard band mode and LTE inband mode. The independent mode corresponds to the network sharing band resources that are not compatible with the traditional LTE (LTE-Long Term Evolution) and LTE-Advance (Enhanced Long Term Evolution), and the LTE protection band mode corresponding to the NB-IoT transmission occupies LTE and LTE- A's protection has resources, while LTE in-band mode shares the same bandwidth for NB-IoT and LTE and LTE-A. When the LTE in-band mode is adopted, the center frequency of the subcarrier corresponding to the NB-IoT transmission needs to be aligned with the center frequency of the LTE and LTE-A transmissions to avoid inter-carrier interference; For the independent mode, the above restrictions do not need to exist. In the existing NB-IoT of Release-13 and Release-14, the independent mode NB-IoT and the in-band mode NB-IoT respectively correspond to different subcarrier center frequency points, and the base station informs the UE of the mode type through system information. (User Equipment, user equipment) to help the UE determine the location of the subcarrier center frequency point.

At present, the NB-IoT system informs the NB-IoT UE base station of the mode type adopted by the NB-IoT system broadcast information to help the NB-IoT UE determine the center frequency point, the Raster-offset (cluster offset), the resource mapping and the like; Currently used 2-bit information to indicate one of the independent mode, the LTE guard band mode and the LTE in-band mode. In the future, if there are NR systems and LTE systems on a single band resource, and there are many different system designs in the NR and LTE systems, then the NB-IoT UE needs to distinguish between the independent mode, the LTE protection band mode, and the LTE band. Internal mode, NR guard band mode, NR in-band mode, five different deployment methods; a simple solution to the above problem is to expand the existing system broadcast information to meet the increased mode, and then the solution problem Therefore, the complexity of the NB-IoT UE distinguishing mode is increased, and the overhead of the NB-IoT system broadcast message is increased; at the same time, the above method is not applicable to the traditional NB-IoT UE, and the traditional NB-IoT UE is applicable. Unable to see the newly added model, which in turn requires upgrades to deployed and mass-produced NB-IoT UEs, which is clearly not the way NB-IoT device manufacturers want.
