Title: METHOD AND DEVICE FOR LOW-LATENCY COMMUNICATION IN USER EQUIPMENT AND BASE STATION
Abstract:
Disclosed are a method and device for low-latency communication in a user equipment and a base station. A base station sends first signalling, the first signalling indicating a first PRB pair set. The base station sends second signalling, the second signalling comprising scheduling information about first data. The second signalling is located in the first PRB pair set on a frequency domain. The first PRB pair set comprises M PRB pair sub-sets. The first signalling is composed of improved EREGs. An RE occupied by one of the improved EREGs is distributed on a PRB pair occupied by one of the PRB pair sub-sets. In the present invention, a new mapping mode of control signalling is designed, thereby ensuring that an RE occupied by the control signalling is mapped to a relatively short time interval. The method ensures that a user can detect control signalling earlier, thus sending or receiving a data channel indicated by the control signalling earlier, reducing the system latency, and guaranteeing a performance gain brought about by system low-latency.
