Abstract

The invention discloses a method and device for determining downlink control information bits and communication equipment, and belongs to the field of communication. The method comprises the following steps: under the condition that a group public physical downlink shared channel (PDSCH) is scheduled through terminal UE specific downlink control information (DCI), a first bit in the UE specific DCI is used for indicating a radio network temporary identifier (RNTI) used for scrambling the PDSCH, and the number of bits of the first bit is determined by the number of group public RNTIs configured to user equipment.

Description

technical field [0001] Embodiments of the present invention relate to the field of communications, and in particular, to a method and a communication device for determining downlink control information bits. Background technique [0002] In the New Radio (NR), the unicast (unicast) physical downlink shared channel (PDSCH) uses terminal-specific downlink control information (Downlink Control Information, DCI), which can also be called terminal-specific (dedicated) DCI or dedicated DCI scheduling, the terminal may also be called terminal equipment or user equipment (User Equipment, UE) to feed back according to the indication information in the DCI, for example, determine the physical uplink control channel (Physical Uplink Control Channel, PUCCH) transmission resources according to the DCI indication and transmission power, etc., in this way, different UEs can be allocated different PUCCH resources, so as to avoid resource conflict, and the received power of different UEs can...
