Detailed ways

The application will be further described in detail below with reference to the drawings and embodiments.

First, there are the following explanations:

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

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

Indicate whether the terminal will detect the control channel in the next period of time, or be in a sleep state for the next period of time;

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

Indicate the minimum time slot offset value of the uplink and downlink data scheduling of the terminal in the next period of time, namely K0, K2; it may also include the time slot offset of the physical downlink shared channel (PDSCH) to the hybrid automatic repeat request (HARQ) ACK The minimum value of the shift value K1;

Indicate the activation or deactivation of the secondary cell (Scell) of carrier aggregation, or indicate the triggering and reporting of aperiodic channel state information (CSI) measurement;

Indicates the switching of the bandwidth part (BWP).

The energy saving signal may be transmitted based on the structure of the control channel. Specifically, the energy saving signal may be transmitted based on the structure of the physical downlink control channel (PDCCH). By detecting the energy-saving signal of the PDCCH structure to achieve the above-mentioned function indication, 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 application, by sending instruction information, the terminal is instructed to detect the search space of the control channel carrying energy saving information.

With the solution of the embodiment of the present application, the configuration of the search space of the energy-saving control channel can be realized by sending the instruction information.

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

Among them, the control channel carrying energy saving information may also be referred to as an energy saving control channel.

Here, in actual application, the search space configuration in NR has the following two types:

First, for the transmission of cell broadcast control information, the common search space (CSS) of this 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 messages (otherSI), paging (paging), and random access response (RAR) is specified through broadcast signaling, and the search space corresponding to these information They are called Type0-PDCCH CSS, Type0A-PDCCH CSS, Type2-PDCCH CSS, Type1-PDCCH CSS. In addition, before the SIB issues the association relationship, it is assumed that these broadcast control information are transmitted in the common search space of type 0, that is, the search space for transmitting RMSI.

The second type is the search space Type3-PDCCH CSS where other common control information such as interrupt transmission indication, time slot format indication, power control command (ie power control command) indication, etc. are located, and the user-specific transmission of UE-specific control information The search space (USS) is configured through PDCCH-Config of RRC signaling. The following is part of the information:

PDCCH-Config information element

The configuration signaling indicates the ID of the search space to be detected to the terminal. The terminal can determine the time-frequency resource location of the PDCCH detection, the detected DCI format, and the aggregation level, etc., 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 of the search space corresponding to the energy-saving signal and the detection position. Since the above-mentioned first method is suitable for 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, namely the RRC signaling configuration.

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

The indication information is carried by RRC configuration information.

Here, in actual application, as mentioned 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 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 the identification of the search space of the control channel carrying energy saving information. For example, the indication information may be added to an IE such as PDCCH-ConfigCommon or PDCCH-Config. The indication information may also instruct the terminal to detect the control channel carrying energy saving information, and the search space of the control channel carrying energy saving information is configured by the network.

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

PDCCH-Config information element

The indication information is added to the PDCCH-ConfigCommon IE to indicate the identification of the search space of the control channel carrying energy saving information in the following manner:

PDCCH-ConfigCommon information element

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

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

PDCCH-Config information element

Here, SetupRelease{powerSaving} indicates to detect the control channel carrying energy saving information; the search space used by the specific 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 difference of control information:

The first type is information corresponding to the type3 public search space. The transmission of this type of control information corresponds to a special DCI format. Therefore, the DCI format of the configured search space can determine which search spaces need to detect this type of control information. There is no need to detect the corresponding control information in the search space where the corresponding format is not configured.

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

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

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

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

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

Wherein, 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 PDCCH candidates.Each search space is associated with one ControlResourceSet.

SearchSpace information element

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

When the control channel carrying energy saving information adopts USS, configure whether the search space detects energy saving signals in the search space configuration.

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

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

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

SearchSpace information element

Among them, it should be noted that the position of the added field can be any position parallel to the above-mentioned 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 at the same level as the search space Id; the indication information indicates whether the control channel carrying energy saving information is detected in the corresponding search space; of course, in practical applications, it can also be the indication The presence of the information instructs the terminal to detect the control channel carrying energy-saving information, that is, instead of adopting the form of BOOLEAN, the indication information is set in the corresponding position of the search space, which means that the corresponding search space is detected to carry 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:

Among them, 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 an information domain of the same level as the DCI format in the user-specific information domain; the indication information indicates whether to detect control channels carrying energy saving information in the corresponding search space; of course; In practical applications, the presence of the indication information may also indicate that the terminal detects the control channel carrying energy saving information, that is, instead of using the form of BOOLEAN, the indication information is set in the corresponding position of the search space, that is, Indicates that the control channel carrying energy saving information is detected in the corresponding search space.

The third type is that 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:

In other words, the indication information searches for an information domain of the same level as the DCI format in the user-specific information domain in the search space IE, and the indication information is the DCI format of the control channel carrying energy saving information.

Another setting method is as follows:

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

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

The use of USS for indication information can better adapt to the user's business characteristics. This is because: Currently, related technologies support 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 cause frequent detection of energy-saving signals. Therefore, the problem can be solved well by configuring the indication information in the search space.

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

Step 101: Receive instruction information;

Specifically, RRC configuration information is received; the RRC configuration information carries the indication information.
