Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The following first describes related concepts mentioned in the embodiments of the present invention as follows.

By detecting the PDCCH-based power saving signal/channel (PS-Ch), the terminal can learn the period of the next period of time (such as the next Discontinuous Reception (DRX)) ) Whether it is necessary to wake up to receive services from the base station (as shown in Figure 1) or sleep, where, in Figure 1, the grid filled box represents PS-Ch, and the oblique line filled box represents the synchronization signal block (Synchronization Signal and PBCH block, SSB) ), the filled box with vertical lines indicates awakened DRX, and the white filled box indicates sleeping DRX.

Specifically, the PS-Ch used to wake up the user to receive is also called a wake-up signal (Wake-up Signal, WUS), and the PS-Ch used to make the user enter the sleep state is also called a Go-to-Sleep signal.

There is also a problem in the prior art that in the monitoring process of the wake-up signal based on the PDCCH, since the terminal needs to consume relatively large power to receive and decode the PDCCH, the energy-saving benefit introduced by the wake-up signal needs to be improved.

For the control resource set (CORESET) demodulation pilot, there are two configurations: if the base station configures the CORESET precoding granularity (precoderGranularity) to be the same as the resource element group (sameAsREG-bundle), it means that there is no configuration For the wideband demodulation reference signal (wideband DMRS), the same precoding is used in the frequency domain within one REG bundle. The pilot signal in this case is called the subband pilot signal; if The base station configures CORESET precoderGranularity to all adjacent radio bearers (allContiguousRBs), which means that wideband DMRS is configured, and the same precoding is used in the frequency domain within the entire CORESET. The pilot signal in this case is called wideband pilot. Frequency signal.

Aiming at the problem that the terminal receiving and decoding PDCCH requires relatively large power consumption, the energy-saving benefit introduced by the wake-up signal cannot be maximized, and provides a decoding and decoding configuration method, terminal and network side equipment.

As shown in FIG. 2, an embodiment of the present invention provides a decoding method applied to a terminal, including:

Step 201: Obtain the detection result of the pilot signal;

For example, the pilot signal mentioned in the embodiment of the present invention may be a demodulation reference signal (Demodulation Reference Signal, DMRS). The terminal performs PDCCH decoding according to the detection result, or the terminal does not perform PDCCH decoding or discards the PDCCH according to the detection result.

Step 202: Perform PDCCH decoding when the detection result indicates that physical downlink control channel decoding is required.

It should be noted that by detecting the pilot signal sent by the network-side device, the terminal can know whether the pilot signal indicates PDCCH decoding. When PDCCH decoding is required, the terminal performs PDCCH decoding, and when instructed not to perform PDCCH decoding, When decoding, the terminal discards the PDCCH.

It should be noted that the embodiment of the present invention is mainly used to realize whether to wake up the terminal. When the detection result indicates that PDCCH decoding is required, it can also be understood that the detection result indicates that the terminal needs to be waked up. As for whether to wake up the terminal, it needs to be based on The result of PDCCH decoding is determined.

Further, the PDCCH is used to carry a wake-up signal.

It should be noted that during the monitoring process of the wake-up signal based on the PDCCH, the pilot signal is detected first, and only when the detection result indicates that PDCCH decoding is required, the PDCCH with the wake-up signal is decoded, so as to avoid the terminal from time to time. Receiving and decoding the PDCCH causes a problem of large power consumption. This method saves the power consumption of the terminal and improves the energy-saving effect of the terminal introduced by the wake-up signal.

The pilot signal in the embodiment of the present invention may include: a broadband pilot signal or sub-band pilot signal belonging to the control resource set (CORESET), or the pilot signal in the embodiment of the present invention may not belong to the control resource set CORESET, either. In other words, the pilot signal does not belong to any CORESET.

Specifically, when the pilot signal belongs to CORESET, the configuration of the CORESET includes at least one of the following:

A11. Configured by high-level signaling;

That is to say, in this case, the CORESET is a dedicated CORESET configured by high-level signaling.

A12. Configured by the Master Information Block (MIB);

That is to say, in this case, the CORESET is the common CORESET of the cell configured by the MIB, that is, CORESET0.

A13. Configured by System Information Block 1 (SIB1);

That is to say, in this case, the CORESET is the common CORESET of the cell configured by SIB1.

What needs to be explained is that since the configuration of CORESET may correspond to the configuration of multiple parameters, when configuring, all parameters can be configured in the same way; some parameters can also be configured in one way, others The parameters adopt another configuration method.

Specifically, it should be noted that the specific implementation of step 201 in the embodiment of the present invention is as follows:

Perform pilot signal detection according to preset information;

If the detection is successful, it is determined that the detection result indicates that PDCCH decoding is required;

If the detection fails, it is determined that the detection result indicates that PDCCH decoding is not required.

It should be noted that, in the embodiment of the present invention, the pilot signal is detected based on preset information, that is, the preset information is used to compare or match the pilot signal. If the comparison is consistent or the match is consistent, then It indicates that the test is successful, otherwise, it indicates that the test has failed.

Further, the preset information is configured by the network side device or calculated by the terminal according to the information configured by the network side device.

Specifically, when the preset information is configured by the network side device, the preset information is one of the following:

B11. A scrambling identifier for at least one terminal;

Specifically, the scrambling identifier may be a physical downlink control channel demodulation reference signal scrambling identifier (pdcch-DMRS-ScramblingID). Further, the scrambling identifier may be for a group of terminals or for a single terminal. .

B12. The first terminal identifier;

It should be noted that, in this case, the preset information is the terminal identifier (i.e., terminal ID), for example, it may be a radio network temporary identity (RNTI), or it may be a globally unique temporary terminal identifier (Globally). Unique Temporary UE Identity (GUTI) can also be the position of the field corresponding to the terminal in the Downlink Control Information (DCI), etc.

B13. The first terminal group identifier;

That is, in this case, the preset information is a group identification (for example, a group ID) configured for a group of terminals.

Specifically, when performing PDCCH decoding, the terminal performs PDCCH decoding through the second terminal identifier or the second terminal group identifier.

It should be noted that the first terminal identifier and the second terminal identifier mentioned above may be the same or different. When the two are different, that is, the type of terminal identifier used by the terminal is different, or the terminal identifier used The length is different. For example, when the terminal uses RNTI for pilot signal detection, the terminal can use GUTI for PDCCH decoding. Of course, in this case, the terminal can also use the same RNTI as the detection pilot signal for decoding. In the same way, the first terminal group identifier and the second terminal group identifier mentioned above may be the same or different. When the two are different, that is, the type of terminal group identifier used by the terminal is different, or the terminal used The length of the group ID is different.

Further, after step 202, the decoding method of the embodiment of the present invention further includes:

When the terminal successfully decodes the PDCCH and the PDCCH indicates that the terminal needs to wake up, then the terminal wakes up; further, when the terminal fails to decode the PDCCH or the terminal successfully decodes the PDCCH, but the PDCCH indicates that the terminal does not need to wake up, Then the terminal wake-up is not performed.

As shown in FIG. 3, the specific implementation of the embodiment of the present invention will be described in detail below in practical applications as follows.

The terminal determines whether the PDCCH needs to be decoded by detecting the pilot signal corresponding to the terminal group ID. When the detection fails, indicating that the terminal does not need to wake up, the terminal does not decode the PDCCH and continues to maintain the sleep state;

When the detection is successful, the terminal obtains whether the terminal needs to be awakened under the user ID (for example, the terminal ID) by decoding the DCI in the PDCCH, if the terminal needs to be awakened, the terminal wakes up; if there is no need to wake up the terminal, the terminal continues to maintain Sleep state.

It should be noted that the embodiment of the present invention can avoid the terminal receiving and decoding the PDCCH from time to time, causing the problem of high power consumption. This method saves the terminal power consumption and improves the energy-saving effect of the terminal; Frequency signal detection optimizes the energy consumption of the wake-up signal, which not only saves the power consumption of the wake-up signal, but also achieves the purpose of notifying the terminal whether it needs to be awakened through the wake-up signal.

As shown in FIG. 4, an embodiment of the present invention provides a decoding configuration method, which is applied to a network side device, and includes:
