US 2022/0190981 A1 · METHOD FOR DETERMINING DOWNLINK CONTROL INFORMATION TYPE, AND APPARATUS

Abstract

The present application provides a method for determining a downlink control information type and an apparatus. The method comprises: a terminal apparatus receiving DCI; the terminal apparatus determining a type of the DCI according to a bit value of a first bit field in the DCI, and/or the terminal apparatus determining the type of the DCI according to a radio network temporary identity (RNTI) used to scramble a cyclic redundancy check (CRC) portion of the DCI, wherein the DCI comprises a first type of DCI and a second type of DCI, the first type of DCI is used to schedule data and instruct the terminal apparatus to operate in a dormant bandwidth part (BWP) or a non-dormant BWP on a secondary cell, and the second type of DCI is used to instruct the terminal apparatus to operate in a dormant BWP or a non-dormant BWP on the secondary cell.

Dependent claims

A method for determining a downlink control information type, comprising:

receiving, by a terminal device, downlink control information (DCI);
and
determining, by the terminal device, a type of the DCI according to a bit value of a first bit field in the DCI, and/or determining, by the terminal device, the type of the DCI according to a radio network tempory identity (RNTI) used for scrambling a cyclic redundancy check (CRC) of the DCI;
wherein the DCI is a first type of DCI and a second type of DCI, the first type of DCI is used for scheduling data and indicating that the terminal device operates on a dormant bandwidth part (BWP) or a non-dormant BWP in a secondary cell, and the second type of DCI is used for indicating that the terminal device operates on the dormant BWP or the non-dormant BWP in the secondary cell.
