摘要

An information configuration method, a data receiving method, and a device are provided. A first network device configures a first resource set group of a physical downlink control channel set for user equipment, and configures for the user equipment, a second resource set group of a physical downlink control channel for retransmission, where the physical downlink control channel for retransmission is a physical downlink control channel for retransmission corresponding to downlink data indicated by a physical downlink control channel in at least one subset of the physical downlink control channel set. The first network device sends information about the first resource set group and information about the second resource set group to the user equipment.

說(shuō)明書(shū)

In a non-ideal backhaul scenario, there is a relatively large delay for information exchange between multiple network devices; therefore, a network device is likely fail to learn a data sending status of another network device in a timely manner, for example, fails to learn whether data sent by another network device is correctly received by UE. Therefore, a dynamic retransmission solution in an ideal backhaul scenario cannot be used, and in the non-ideal backhaul scenario, a coordination gain cannot be obtained by means of coordination between multiple network devices in an aspect of data transmission.

For a same network device, the network device may perform coordination in an aspect of data transmission by means of quick information exchange between multiple modules in the network device, so that a coordination gain is obtained. However, the solution to implementing quick information exchange between multiple modules is relatively complex.

SUMMARY

Embodiments of the present invention provide an information configuration method, a data receiving method, and a device, so that a coordination gain can still be obtained without quick information exchange.

According to a first aspect, an information configuration method is provided, including:
