Abstract

An information transmission method includes: receiving the DCI sent by a base station, wherein the DCI carries a secondary cell (SCell) dormancy indication information field; obtaining indication information for the SCell dormancy indication information field; and obtaining, according to the indication information and the SCell dormancy indication information field, an actual indication represented by the SCell dormancy indication information field for monitoring a physical downlink control channel (PDCCH).

First claim

What is claimed is:

1 . An information transmission method, applied to a scenario where downlink control information (DCI) carries scheduling information, and comprising:
receiving the DCI sent by a base station, wherein the DCI carries a secondary cell (SCell) dormancy indication information field; obtaining indication information for the SCell dormancy indication information field; and obtaining, according to the indication information and the SCell dormancy indication information field, an actual indication represented by the SCell dormancy indication information field for monitoring a physical downlink control channel (PDCCH); wherein obtaining, according to the indication information and the SCell dormancy indication information field, the actual indication represented by the SCell dormancy indication information field for monitoring a physical downlink control channel (PDCCH) comprises: in response to determining that the indication information is a first value, determining that the SCell dormancy indication information field represents an indication of whether the SCell or a SCell group is dormant; or in response to determining that the indication information is a second value, determining that the SCell dormancy indication information field represents one of:
a joint indication of dormancy and/or adaptation of a primary cell (PCell) and dormancy and/or adaptation of the SCell or the SCell group;
an indication of dormancy and/or adaptation of the PCell; or
an indication for configuring the SCell dormancy indication information field as default information bits.

2 . The method according to claim 1 , wherein obtaining the indication information for the SCell dormancy indication information field comprises:
receiving a signaling carrying the indication information sent by the base station, wherein the signaling carries a target information field, and the target information field is configured to carry the indication information; or the signaling is a first high-layer signaling, and the indication information is configured according to configuration information of high-layer parameters, or determining a target parameter on a terminal side as the indication information, wherein the target parameter is configured for the indication information, and the target parameter comprises at least one selected from a version parameter of the terminal and a capability parameter of the terminal.

3 . The method according to claim 2 , wherein the target information field at least comprises a carrier indicator field in the DCI, and the signaling is the DCI,
wherein when the carrier indicator field is configured to carry the indication information, if an assignment of the carrier indicator field is zero or the carrier indicator field is zero bit, interpreting the SCell dormancy indication information field as representing an indication of whether the SCell or a SCell group is dormant; if the assignment of the carrier indicator field is non-zero, interpreting the SCell dormancy indication information field as representing one of:
a joint indication of dormancy and/or adaptation of a PCell and dormancy and/or adaptation of the SCell group;
an indication of the dormancy and/or the adaptation of the PCell; or
an indication for configuring the SCell dormancy indication information field as default information bits.

4 . The method according to claim 1 , further comprising:
obtaining an information field size of the SCell dormancy indication information field, wherein obtaining the information field size of the SCell dormancy indication information field comprises: receiving a second high-layer signaling sent by the base station, and extracting the information field size from the second high-layer signaling, wherein the method further comprises: switching a monitoring behavior of a PCell and/or a monitoring behavior of the SCell or a SCell group according to the indication represented for monitoring the PDCCH.

5 . The method according to claim 1 , further comprising:
receiving a third high-layer signaling sent by the base station; and configuring an adaptation behavior of the PCell according to the third high-layer signaling, in response to determining that the SCell dormancy indication information field represents the indication of the adaptation of the PCell, wherein the adaptation behavior of the PCell comprises performing monitoring according to candidate values of one or more parameters in a parameter set configured for PDCCH monitoring, and the candidate values are a subset of values in a value set configured for the one or more parameters, or values different from those in the value set, or receiving a fourth high-layer signaling sent by the base station; and configuring a dormancy behavior of the PCell according to the fourth high-layer signaling, in response to determining that the SCell dormancy indication information field represents the indication of the dormancy of the PCell, wherein the dormancy behavior of the PCell comprises skipping one or more PDCCH monitoring occasions, or receiving a fifth high-layer signaling sent by the base station; and configuring a joint monitoring behavior of the PCell comprising a dormancy behavior and an adaptation behavior according to the fifth high-layer signaling, in response to determining that the SCell dormancy indication information field represents the indication of the dormancy and the adaptation of the PCell, wherein the joint monitoring behavior comprises skipping one or more PDCCH monitoring occasions, and performing adaptation adjustment on one or more parameters in a parameter set configured for PDCCH monitoring, or determining a value corresponding to the SCell dormancy indication information field as the joint indication, and decoding monitoring behaviors of the PCell and the SCell or the SCell group according to the value, in response to determining that the SCell dormancy indication information field represents the joint indication of the dormancy and/or the adaptation of the PCell and the dormancy and/or the adaptation of the SCell or the SCell group, or receiving a sixth high-layer signaling sent by the base station; and extracting a mapping relationship between the joint indication and monitoring behaviors of the PCell and the SCell or the SCell group from the sixth high-layer signaling, in response to determining that the SCell dormancy indication information field represents the joint indication of the dormancy and/or the adaptation of the PCell and the dormancy and/or the adaptation of the SCell or the SCell group.

6 . A terminal, applied to a scenario where DCI carries scheduling information, and comprising:
a memory; a transceiver; and a processor; wherein the memory is configured to store computer programs; the transceiver is configured to send or receive data under a control of the processor, and the processor is configured to read the computer programs in the memory to perform acts of the method according to claim 1 .

7 . A non-transitory processor-readable storage medium having stored therein computer programs that, when executed by a processor, cause the processor to perform the information transmission method according to claim 1 .

8 . An information transmission method, applied to a scenario where downlink control information (DCI) carries scheduling information, and comprising:
configuring a secondary cell (SCell) dormancy indication information field in the DCI; configuring indication information for the SCell dormancy indication information field, wherein the indication information is configured to instruct a terminal to obtain an actual indication represented by the SCell dormancy indication information field for monitoring a physic
