Abstract
Methods and apparatuses for information transmission are provided. The method includes that first downlink control information (DCI) is received by a terminal device. The first DCI includes first indication information for indicating a maximum number of multiple-input multiple-output (MIMO) layers for receiving data by the terminal device.
Claims19
A method for information transmission, applied to a terminal device, the method comprising:
- receiving first downlink control information (DCI), wherein the first DCI comprises first indication information for indicating a first maximum number of multiple-input multiple-output (MIMO) layers for receiving data by the terminal device,
- wherein the method further comprises:
- receiving radio resource control (RRC) signaling indicating a second maximum number of MIMO layers;
- and
- receiving the data based on the first maximum number of MIMO layers indicated by the first indication information when the first maximum number of MIMO layers indicated by the first indication information is smaller than the second maximum number of MIMO layers indicated by the RRC signaling.
A method for information transmission, applied to a network device, the method comprising:
- transmitting first downlink control information (DCI), wherein the first DCI comprises first indication information for indicating a first maximum number of multiple-input multiple-output (MIMO) layers for receiving data by a terminal device,
- wherein the method further comprises:
- transmitting radio resource control (RRC) signaling indicating a second maximum number of MIMO layers, wherein the first maximum number of MIMO layer and the second maximum number of MIMO layers are used for the terminal device to receive the data based on the first maximum number of MIMO layers indicated by the first indication information when the first maximum number of MIMO layers indicated by the first indication information is smaller than the second maximum number of MIMO layers indicated by the RRC signaling.
An apparatus for information transmission, provided in a terminal device, the apparatus comprising a processor and a transceiver connected to the processor, wherein:
- the processor is configured to control the transceiver to receive first downlink control information (DCI), wherein the first DCI comprises first indication information for indicating a first maximum number of multiple-input multiple-output (MIMO) layers for receiving data by the terminal device, and the processor is further configured to control the transceiver to:
- receive radio resource control (RRC) signaling indicating a second maximum number of MIMO layers;
- and
- receive the data based on the first maximum number of MIMO layers indicated by the first indication information when the first maximum number of MIMO layers indicated by the first indication information is smaller than the second maximum number of MIMO layers indicated by the RRC signaling.
