Communication method and apparatus

The terminal device selects some resources from multiple first-level pilot resources and measures and reports the associated second-level pilot resources, which solves the problem of beam selection restriction caused by the limit on the number of pilot resources in the 5G communication system and improves the air-interface transmission capability.

AI Technical Summary

Technical Problem

In 5G communication system, when measuring beams, the terminal equipment may be limited due to the limit of pilot resources, which may affect the air-interface transmission capability.

Method used

By receiving the configuration information sent by the network device, the terminal device selects some resources from the multiple first-level pilot resources and measures and reports the associated second-level pilot resources, reducing the measurement complexity and ensuring the air-interface transmission capability.

Benefits of technology

Without increasing the measurement complexity of terminal equipment, it is possible to select potential service pilot resources from a larger set of pilot resources for measurement and reporting, improving the air-interface transmission capability of terminal equipment.

Abstract

Embodiments of the present application disclose a communication method and apparatus. The method comprises: a terminal device receiving configuration information sent by a network device, the configuration information comprising a number M of first-level pilot resource numbers and a number X of second-level pilot resources, one of the first-level pilot resources being associated with one or more of the second-level pilot resources, and M and X being integers greater than 0; selecting a number N of first-level pilot resources from among the M first-level pilot resources, and measuring a number Y of second-level pilot resources, among the X second-level pilot resources, associated with the N first-level pilot resources. Using an embodiment of the present application, measurement complexity for a terminal device can be reduced, and air interface transmission capability of the terminal equipment ensured.
