Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

First, there is the following explanation:

The functions implemented by the energy-saving signal may include one or more of the following:

Indicates whether the terminal needs to detect the control channel during the next discontinuous reception (DRX) duration (on duration);

Indicates whether the terminal detects the control channel in the next period of time, or is in a sleep state in the next period of time;

Indicates the maximum number of multiple-input multiple-output (MIMO) streams used by the terminal;

Indicates the minimum time slot offset value of the terminal's uplink and downlink data scheduling in the next period of time, namely K0, K2; it may also include the time slot offset from the Physical Downlink Shared Channel (PDSCH) to the Hybrid Automatic Repeat Request (HARQ) ACK the minimum value of the shift value K1;

Indicates the activation or deactivation of a secondary cell (Scell) for carrier aggregation, or instructs aperiodic channel state information (CSI) measurement triggering and reporting;

Indicates the handover of the Bandwidth Part (BWP).

The energy-saving signal may be transmitted based on the structure of the control channel, and specifically, the energy-saving signal may be transmitted based on the structure of the PDCCH. By detecting the energy-saving signal of the PDCCH structure to realize the indication of the above function, it is necessary to configure a corresponding search space for the PDCCH carrying the energy-saving signal.

Based on this, in various embodiments of the present invention, by sending the indication information, the terminal is instructed to detect the search space of the control channel carrying the energy saving information.

By adopting the solution of the embodiment of the present invention, the configuration of the energy-saving control channel search space can be realized by sending the indication information.

An embodiment of the present invention provides an information transmission method, which is applied to a network device (such as a base station, etc.), and the method includes:

Sending indication information; the indication information is used by the terminal to determine the search space of the control channel carrying the energy saving information.

The control channel carrying the energy saving information may also be referred to as an energy saving control channel.

Here, in practical application, there are two configurations of search space in NR:

First, for the transmission of cell broadcast control information, the common search space (CSS) of these information associates the type of control information with the search space through the cell-specific signaling PDCCH-ConfigCommon sent in the system message block (SIB). . The following is part of the information:

PDCCH-ConfigCommon information element

The search space ID associated with the remaining minimum system information (RMSI), SIB1, other system information (otherSI), paging (paging), and random access response (RAR) is specified through broadcast signaling, and the search space corresponding to these information They are respectively called Type0-PDCCH CSS, Type0A-PDCCH CSS, Type2-PDCCH CSS, Type1-PDCCH CSS. In addition, before the SIB issues the association relationship, by default, the broadcast control information is transmitted in the public search space of type 0, that is, the search space for transmitting RMSI.

Second, for some other common control information such as interrupt transmission indication, time slot format indication, power control command indication, etc., the search space Type3-PDCCH CSS is located, and the user-specific search space (USS) for transmitting UE-specific control information is Configured through the PDCCH-Config of RRC signaling, the following is part of the information:

PDCCH-Config information element

The ID of the search space that needs to be detected is indicated to the terminal through the configuration signaling. The terminal can then determine the time-frequency resource location for PDCCH detection, the detected DCI format, and the aggregation level according to the corresponding search space configuration.

When designing an energy-saving signal based on the structure of the PDCCH, it is necessary to configure the period and detection position of the search space corresponding to the energy-saving signal. Since the above-mentioned first method is applicable to the search space configuration of some broadcast control channels, the configuration of the search space of the energy-saving signal is more reasonable through the above-mentioned second method, that is, the RRC signaling configuration method.

Based on this, in an embodiment, when the indication information is sent, the method may include:

The indication information is carried through RRC configuration information.

Here, in practical application, as described above, the control information is generally configured through the PDCCH-Config IE of the RRC signaling. The indication information may also be configured through the PDCCH-ConfigCommon IE of the RRC signaling.

Based on this, in an embodiment, when the indication information is carried by the RRC configuration information, the indication information may be set in the control channel configuration IE in the RRC signaling. The indication information may indicate an identifier of the search space of the control channel carrying the energy saving information, for example, the indication information is added to IEs such as PDCCH-ConfigCommon or PDCCH-Config. The indication information may also instruct the terminal to detect the control channel carrying the energy saving information, and the search space of the control channel carrying the energy saving information is configured by the network.

The manner of adding the indication information to the PDCCH-Config IE to indicate the identifier of the search space of the control channel carrying the energy saving information is as follows:

PDCCH-Config information element

The indication information is added to the PDCCH-ConfigCommon IE, and the manner of indicating the identifier of the search space of the control channel carrying the energy saving information is as follows:

PDCCH-ConfigCommon information element

Here, SearchSpaceId indicates a search space ID for detecting a control channel carrying energy saving information.

The indication information is added to the PDCCH-Config IE to instruct the terminal to detect the control channel carrying the energy saving information in the following manner:

PDCCH-Config information element

Here, SetupRelease{powerSaving} indicates that the control channel carrying energy saving information is to be detected; the specific search space used by the control channel is configured by the network, and the search space used by the control channel carrying energy saving information is configured through the search space IE.

For the second method above, it is divided into the following two categories according to the different control information:

The first type is the information corresponding to the public search space of type 3. The transmission of this type of control information corresponds to a special DCI format. Therefore, it is possible to determine which search spaces need to detect this type of control information through the DCI format of the configured search space. The corresponding control information does not need to be detected in the search space where the corresponding format is not configured.

The second category is the information corresponding to USS. This type of control information scrambled by C-RNTI, MCS-C-RNTI, SP-CSI-RNTI, or CS-RNTI(s) needs to be detected in all USSs when the corresponding RNTI is configured for detection detection.

Based on this, in practical applications, the control channel carrying the energy saving information may use a common search space of type 3, or USS may be used.

Based on this, in an embodiment, when the indication information is carried by the RRC configuration information, the method further includes:

The indication information is set in the search space configuration in the RRC signaling.

Here, when the control channel carrying the energy saving information adopts the common search space of type 3, the indication information can use a special DCI format x-y. In the search space configuration, when the search space type is common (expressed as common in English), if If the corresponding DCI format x-y is configured, it indicates that the terminal needs to detect the control channel carrying the energy saving information at the time-frequency resource position corresponding to the search space; for example, adding dci-Formatx-y after the existing dci-Format2-3, to indicate that the control channel carrying energy saving information is detected in the common search space.

Based on this, in an embodiment, the indication information is located in the information field of the search space IE where the search space type is common; the indication information is the DCI format of the control channel carrying the energy saving information.

The manner of setting the indication information in the search space IE is as follows:

SearchSpace

The IE SearchSpace defines how/where to search for PDCCHcandidates. Each search space is associated with one ControlResourceSet.

SearchSpace information element

Here, the common search space transmits energy-saving signals, which has the advantage of saving network resources. Multiple terminals can share energy-saving signals. Among the information carried by the energy-saving signals, different terminals can share the same energy-saving indication information, or different terminals can occupy different information. domain to transmit energy saving indication information.

When the USS is used for the control channel carrying the energy saving information, whether to detect the energy saving signal in the search space is configured in the search space configuration.

Based on this, in an embodiment, the indication information is located in the information field of the search space IE where the search space type is user-specific.

Here, the specific implementation of the configuration can be divided into the following three ways:

The first is to add a domain to the search space IE to set the indication information. The location of the domain can be placed in the SearchSpace IE with searchSpaceId, controlResourceSetId, monitoringSlotPeriodicityAndOffset, duration, monitoringSymbolsWithinSlot, and nrofCandidates side by side, that is, at the same level as these domains, as shown below :

SearchSpace information element

It should be noted that the position of the added field may be any position parallel to the above field, and the name of the field is not limited to the example name (powerSavingDetecion).

That is to say, the indication information is in the information domain of the same level as the search space Id; the indication information indicates whether the control channel carrying the energy saving information is detected in the corresponding search space; of course, in practical application, the indication may also be the indication The existence of the information instructs the terminal to detect the control channel carrying the energy-saving information, that is, it is not in the form of BOOLEAN, but the indication information is set in the corresponding position of the search space, which means that the corresponding search space is used to detect the control channel that carries the energy-saving information. control channel.

Second, when the searchSpaceType field is ue-specific, in addition to dci-Formats, add a field to set the indication information, as shown below:

It should be noted that the name of the domain is not limited to the example name (powerSavingDetecion).

That is to say, the indication information in the search space IE searches for the information domain of the same level as the DCI format in the information domain of the user-specific information domain; the indication information indicates whether to detect the control channel carrying the energy saving information in the corresponding search space; of course , in practical application, the existence of the indication information may also instruct the terminal to detect the control channel carrying the energy-saving information, that is, instead of taking the form of BOOLEAN, the indication information is set at the corresponding position of the search space, that is, Indicates that a control channel carrying energy saving information is detected in the corresponding search space.

Third, when searchSpaceType is ue-specific, in addition to dci-Formats, a DCI format m-n corresponding to energy saving information is added. One setting method is as follows:

That is to say, the indication information searches for an information field of the same level as the DCI format in the user-specific information field in the search space IE, and the indication information is the DCI format of the control channel carrying the energy saving information.

Another way to set it up is as follows:

That is to say, the indication information is within the enumeration value range of the DCI format in the user-specific information field in the search space IE, and the indication information is the DCI format of the control channel carrying the energy saving information.

The UE detects that the DCI format m-n exists in the search space, and then detects the control channel carrying the energy saving channel in the search space.

Using the USS for the indication information can better adapt to the service characteristics of the user. This is because: at present, the related technology supports the configuration of 10 search spaces per BWP, that is, there may be multiple user-specific search spaces. In this case, the terminal cannot distinguish which user-specific search space is used to detect energy-saving signals. The direct way is to detect energy-saving signals in all UE-specific search spaces, which may bring about frequent detection of energy-saving signals. Therefore, this problem can be well solved by configuring the indication information in the search space.

Correspondingly, an embodiment of the present invention provides an information transmission method, which is applied to a terminal. As shown in FIG. 1 , the method includes:
