Method for determining trigger state, terminal device, and network device
View Patent ↗Provided in embodiments of the present application are a method and apparatus for determining trigger state, a terminal device, and a communication device; the method comprises: a terminal device receiving first configuration information sent by a network device, the first configuration information comprising configuration information of at least one trigger state; the terminal device receiving first control information sent by the network device, the first control information comprising a first information domain; the terminal device determining a first trigger state identifier on the basis of the value of the first information domain, and determining a corresponding first trigger state in the first configuration information on the basis of the first trigger state identifier; or, the terminal device determining a first trigger state at a target position in the first configuration information on the basis of the value of the first information domain.
1. A method for determining a triggering state, comprising:
receiving, by a terminal device, first configuration information from a network device, wherein the first configuration information is radio resource control (RRC) signalling for configuring a CSI-SemiPersistentOnPUSCH-TriggerStateList, and the first configuration information comprises configuration information of at least one triggering state;
receiving, by the terminal device, downlink control information (DCI) from the network device, wherein the DCI comprises a channel state information (CSI) request field; and
determining, by the terminal device, based on a codepoint of the CSI request field, the first triggering state at a target position in the first configuration information,
wherein a position of each of the at least one triggering state in the first configuration information corresponds to a codepoint of the CSI request field, a starting codepoint of the CSI request field corresponding to a triggering state is 0, and codepoints of the CSI request field correspond in an ascending order to triggering states from a first position to a last position for the triggering states in the first configuration information.
2. The method according to claim 1 , wherein the configuration information of each of the at least one triggering state in the first configuration information comprises a second information field, and the second information field indicates a triggering state ID of the triggering state.
3. The method according to claim 2 , wherein: the first configuration information further comprises the second information field, wherein the second information field indicates a triggering state ID of the semi-consistent triggering state.
4. A terminal device, comprising: a processor, a transceiver and a memory for storing a computer program, wherein the processor is configured to call and execute the computer program stored in the memory, to:
receive first configuration information from a network device through the transceiver, wherein the first configuration information is radio resource control (RRC) signalling for configuring a CSI-SemiPersistentOnPUSCH-TriggerStateList, and the first configuration information comprises configuration information of at least one triggering state;
receive downlink control information (DCI) from the network device through the transceiver, wherein the DCI comprises a channel state information (CSI) request field; and
determine, based on a codepoint of the CSI request field, the first triggering state at a target position in the first configuration information,
wherein a position of each of the at least one triggering state in the first configuration information corresponds to a codepoint of the CSI request field, a starting codepoint of the CSI request field corresponding to a triggering state is 0, and codepoints of the CSI request field correspond in an ascending order to triggering states from a first position to a last position for the triggering states in the first configuration information.
5. The terminal device according to claim 4 , wherein the configuration information of each of the at least one triggering state in the first configuration information comprises a second information field, and the second information field indicates a triggering state ID of the triggering state.
6. The terminal device according to claim 5 , wherein:
the first configuration information further the first configuration information further comprises the second information field, wherein the second information field indicates a triggering state ID of the semi-consistent triggering state.
