Method and apparatus for obtaining configuration information
First Claim
1. A method for obtaining configuration information of a grant-free transmission unit, comprising:
- receiving, by an access device, configuration information of a grant-free transmission unit of the access device, wherein the grant-free transmission unit refers to a transmission resource for grant-free transmission, and the configuration information of the grant-free transmission unit comprises at least one or more of the following information;
information about the grant-free transmission unit or information about a grant-free transmission control mechanism, whereinthe information about the grant-free transmission unit is one or more of the following information;
time-domain resource information, frequency-domain resource information, space-domain resource information, code-domain resource information, or pilot resource information; and
the information about the grant-free transmission control mechanism is one or more of the following information;
uplink power control information, modulation and coding scheme information, or retransmission mechanism information;
receiving, by the access device, information about a grant-free area to which the access device belongs, wherein the grant-free area is a set of one or more access devices, and the configuration information of the grant-free transmission unit of the access device is configuration information of a grant-free transmission unit in the grant-free area to which the access device belongs;
sending, by the access device, the configuration information of the grant-free transmission unit to one or more terminal devices in a coverage area of the access device; and
receiving, by the access device from the one or more terminal devices, data transmitted based on the configuration information of the grant-free transmission unit.

Abstract
The present invention discloses a method and an apparatus for obtaining configuration information of a grant-free transmission unit. A centrally configured network element sends configuration information of a grant-free transmission unit of an access device to the access device, where the grant-free transmission unit refers to a transmission resource used for grant-free transmission, and the configuration information of the grant-free transmission unit includes at least one or more of the following information: information about the grant-free transmission unit or information about a grant-free transmission control mechanism. By using the method and the apparatus for obtaining configuration information of a grant-free transmission unit, an access device can obtain configuration information of a grant-free transmission unit.
