摘要

This application provides a control channel detection method, apparatus, and device. The method includes: A terminal device determines that resources of at least two candidate control channels overlap, where any two of the at least two candidate control channels are located in different search spaces; and the terminal device detects only at least one first candidate control channel in the at least two candidate control channels. This improves control channel detection reliability.

說明書

In a possible implementation, if a CRC of the control channel is scrambled by using a C-RNTI and/or a CS-RNTI, a start resource block of the data channel scheduled through the control channel is a start resource block in a bandwidth part (BWP), and the bandwidth part is a bandwidth part indicated by a first candidate control channel.

In another possible implementation, if a CRC of the control channel is scrambled by using a first RNTI, a start resource block of the data channel scheduled through the control channel is a start resource block in a control-resource set, or a start resource block of the data channel scheduled through the control channel is a width of a start resource in an initial bandwidth part.

Optionally, the first RNTI is an RNTI that does not include at least a C-RNTI and/or a CS-RNTI.

In another possible implementation, if a CRC of the control channel is scrambled by using an SI-RNTI or a CRC of the control channel is scrambled by using a P-RNTI, a start resource block of the data channel scheduled through the control channel is a start resource block in a control-resource set, and the control-resource set is a control-resource set associated with a search space set in which the control channel is located; or a start resource block of the data channel scheduled through the control channel is a width of a start resource in an initial bandwidth part.

In another possible implementation, if a CRC of the control channel is scrambled by using a second RNTI, a start resource block of the data channel scheduled through the control channel is a start resource block in a bandwidth part (BWP), and the bandwidth part is a bandwidth part indicated by a first candidate control channel.

Optionally, the second RNTI is a C-RNTI and/or a CS-RNTI.
