Abstract

The present application discloses an information indication method and apparatus, network equipment, and terminal equipment. The method includes: the network equipment sends first configuration information to the terminal equipment, where the first configuration information is used to configure the first PRACH resource, The first configuration information is used to determine first indication information, where the first indication information is used by the terminal device to determine a target beam and / or a target cell corresponding to the random access procedure initiated based on the second PRACH resource.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to an information indication method and device, network equipment, and terminal equipment. Background technique [0002] It has been agreed in 3GPP RAN2 that UE should prioritize dedicated PRACH resources (if configured) over common Physical Random Access Channel (PRACH) resources. However, radio conditions may change rapidly, especially in small cell environments due to beam scanning and UE mobility, and UEs may not be able to utilize any dedicated PRACH resources for access. When the radio quality of the beam with dedicated resources is not enough for access, the UE needs to use the common PRACH resources provided by the network NW to access the target NW node via some other beams. As mentioned earlier, it would be beneficial if the NW could indicate a preferred beam for the UE, e.g. for better load balancing between beams / transmission points (TRPs) a...
