Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The related concepts mentioned in the embodiments of the present invention will be explained below.
The terminal may know whether to wake up to receive traffic (as shown in fig. 1) from the base station or sleep in a subsequent period (for example, a period of next Discontinuous Reception (DRX)) by detecting a PDCCH-based power saving Signal/channel (hereinafter referred to as PS-Ch), where in fig. 1, a grid filling box represents PS-Ch, a diagonal filling box represents a Synchronization Signal block (Synchronization Signal and PBCH block, SSB), a vertical filling box represents awake DRX, and a white filling box represents sleep DRX.
Specifically, the PS-Ch for waking up a user's reception is also called a Wake-up Signal (WUS), and the PS-Ch for bringing a user into a Sleep state is also called a Go-to-Sleep Signal.
In the prior art, in the process of monitoring the wake-up signal based on the PDCCH, since the power consumption required by the terminal to receive and decode the PDCCH is relatively large, the energy-saving benefit introduced by the wake-up signal needs to be improved.
For the demodulation pilot of the CORESET (control resource set), there are two configurations: if the base station configures CORESET precoding granularity (precoding granularity) to be the same as the resource element group (sameaasereg-bundle), which means that a wideband demodulation reference signal (wideband DMRS) is not configured, the same precoding is used in the frequency domain within 1 REG bundle, and the pilot signal in this case is called a subband pilot signal; if the base station configures the CORESET precoding granularity to all adjacent radio bearers (allcontiguous rbs), meaning that wideband DMRSs are configured, the same precoding is used in the entire frequency domain within the CORESET, and the pilot signal in this case is called a wideband pilot signal.
The invention provides a decoding and decoding configuration method, a terminal and network side equipment, aiming at the problem that the energy-saving benefit introduced by a wake-up signal cannot be maximized because the terminal needs to consume relatively large power for receiving and decoding a PDCCH.
As shown in fig. 2, an embodiment of the present invention provides a decoding method, applied to a terminal, including:
step 201, obtaining a detection result of a pilot signal;
for example, the pilot Signal in the embodiment of the present invention may be a Demodulation reference Signal (DMRS). And the terminal performs PDCCH decoding according to the detection result, or does not perform PDCCH decoding or discards the PDCCH according to the detection result.
Step 202, when the detection result indicates that the decoding of the physical downlink control channel is required, performing PDCCH decoding.
The terminal detects the pilot signal transmitted by the network side device, and thus can know whether the pilot signal instructs PDCCH decoding, and when PDCCH decoding is necessary, the terminal performs PDCCH decoding, and when PDCCH decoding is not instructed, the terminal discards the PDCCH.
It should be noted that the embodiments of the present invention are mainly used to implement whether to wake up a terminal, and 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 woken up, and as for whether the terminal needs to be woken up at the end, the determination needs to be performed according to a result of PDCCH decoding.
Further, the PDCCH is used to carry a wake-up signal.
It should be noted that, in the process of monitoring the wake-up signal based on the PDCCH, the pilot signal is detected first, and only when the detection result indicates that the PDCCH decoding is required, the PDCCH carrying the wake-up signal is decoded, so that the problem that the terminal receives and decodes the PDCCH constantly to cause large power consumption is avoided.
The pilot signal of the embodiment of the present invention may include: the wideband pilot signal or the subband pilot signal belonging to the control resource set (CORESET), or the pilot signal of the embodiment of the present invention may not belong to the control resource set CORESET, that is, the pilot signal does not belong to any CORESET.
Specifically, when the pilot signal belongs to the CORESET, the CORESET is configured in a manner including at least one of:
a11, configuring by high-level signaling;
that is, in this case, the core set is a dedicated core set configured for higher layer signaling.
A12, configured by a Master Information Block (MIB);
that is, in this case, the CORESET is configured for the MIB and belongs to a common CORESET of the cell, that is, CORESET0.
A13, configured by a System Information Block one (System Information Block 1, SIB 1);
that is, in this case, the CORESET is a CORESET common to the cells configured with SIB 1.
It should be noted that, when performing CORESET configuration, configuration of multiple parameters may be corresponded, and when performing configuration, all parameters may be configured in the same manner; or, some parameters may adopt one configuration mode, and other parameters adopt another configuration mode.
Specifically, it should be noted that, in the embodiment of the present invention, a specific implementation manner of step 201 is:
detecting a pilot signal according to preset information;
if the detection is successful, determining that the detection result indicates that the PDCCH decoding is required;
and if the detection fails, determining that the detection result indicates that the PDCCH decoding is not required.
It should be noted that, in the embodiment of the present invention, the pilot signal is detected according to the preset information, that is, the preset information is used to compare or match with the pilot signal, if the comparison is consistent or the matching is consistent, the detection is successful, otherwise, the detection is 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 for the network side device, the preset information is one of the following items:
b11, scrambling identification aiming at least one terminal;
specifically, the scrambling identifier may be a pdcch demodulation reference signal scrambling identifier (pdcch-DMRS-ScramblingID), and further, the scrambling identifier may be specific to a group of terminals or a single terminal.
B12, a first terminal identifier;
in this case, the preset Information is a terminal identifier (i.e. a terminal ID), and may be, for example, a Radio Network Temporary Identifier (RNTI), a Globally Unique Temporary terminal identifier (GUTI), or a location of a field corresponding to the terminal in Downlink Control Information (DCI).
B13, identifying a first terminal group;
that is, in this case, the preset information is a group identification (e.g., 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, and when they are different, that is, the types of the terminal identifiers used by the terminals are different, or the lengths of the terminal identifiers used by the terminals are different. For example, when the terminal performs pilot signal detection using the RNTI, the terminal may perform PDCCH decoding using the GUTI, but in this case, the terminal may perform decoding using the same RNTI as the RNTI used for pilot signal detection. Similarly, the first terminal group identifier and the second terminal group identifier mentioned above may be the same or different, and when the two identifiers are different, that is, the types of the terminal group identifiers used by the terminals are different, or the lengths of the terminal group identifiers used by the terminals are 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 be awakened, the terminal is awakened; further, when the terminal fails to decode the PDCCH or the terminal succeeds in decoding the PDCCH but the PDCCH indicates that the terminal does not need to wake up, the terminal does not wake up.
As shown in fig. 3, the following describes in detail the specific implementation of the embodiment of the present invention in practical application.
The terminal determines whether the PDCCH needs to be decoded or not by detecting a pilot signal corresponding to the ID of the terminal group, and when the detection fails, the terminal does not need to wake up, does not decode the PDCCH and continues to maintain a sleep state;
when the detection is successful, the terminal acquires whether the terminal needs to be woken up under the user ID (for example, the user ID may be the terminal ID) by decoding DCI in the PDCCH, and if the terminal needs to be woken up, the terminal wakes up, and if the terminal does not need to be woken up, the terminal continues to maintain the sleep state.
It should be noted that, the embodiment of the present invention can avoid the problem of large power consumption caused by the terminal receiving and decoding the PDCCH at any time, and this way saves the power consumption of the terminal and improves the energy saving effect of the terminal; furthermore, the pilot signal is detected, so that the energy consumption of the wake-up signal is optimized, the power consumption of the wake-up signal is saved, and the purpose of informing whether the terminal needs to be awakened or not through the wake-up signal is achieved.
As shown in fig. 4, an embodiment of the present invention provides a decoding configuration method, applied to a network device, including:
step 401, sending a pilot signal to a terminal;
and the detection result of the pilot signal is used for indicating whether the terminal needs to decode a Physical Downlink Control Channel (PDCCH).
Wherein, the PDCCH is used for carrying the wake-up signal.
