Description

Power-saving signal transmission method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for transmitting power saving signals.

Background

In a 5G system, based on the mobility of a User Equipment (UE), in a use process of the UE, frequently triggered procedures include, but are not limited to, a random access procedure and a paging procedure.

In the random access procedure: a UE sends a Random Access Preamble (Preamble) sequence (i.e. message 1, Msg1) on a Physical Random Access Channel (PRACH); the UE receives a Random Access Response (RAR) message (i.e., message 2, Msg2) on a Physical Downlink Control Channel (PDCCH)/a Physical Downlink Shared Channel (PDSCH); the UE sends a message 3(Msg3) on a Physical Uplink Shared Channel (PUSCH) Channel; the UE receives a contention resolution message (i.e., message 4, Msg4) on the PDSCH channel.

When the UE configures Discontinuous Reception (DRX), the UE will monitor the PDCCH discontinuously. The UE monitors the PDCCH only during DRX active period (i.e., DRX on duration) or when an Inactivity timer (Inactivity timer) is not expired.

Referring to fig. 1, during a DRX cycle, a UE monitors a PDCCH only during an On duration period, and during a DRX occasion (Opportunity for DRX), i.e., a DRX off time, the UE does not receive a PDCCH other than scheduling broadcast signaling to reduce power consumption, i.e., enters a sleep state.

In the standard protocol TR38.213 of Rel-15, it is provided that when resource allocation is performed between different physical channels, the following is provided:

1. when the resources allocated to the candidate PDCCH overlap with the resources allocated to the SSB/PBCH, the following rules apply:

if the UE has not started PDCCH candidate detection for the Common Search Space (CSS) of Type-0PDCCH, the UE does not perform PDCCH candidate detection when there is a resource collision:

1) if at least one Resource Element (RE) is overlapped between the resources allocated to the PDCCH candidates of the Type-0PDCCH CSS and the resources allocated to the SSB/PBCH configured in the SIB1 message, the UE does not perform PDCCH candidate monitoring.

2) If at least one RE is overlapped between the resources allocated to the candidate PDCCH of the Type-0PDCCH CSS and the resources allocated to the SSB/PBCH configured in the public information (ServinCellConfigCommon) of the serving cell, the UE does not perform the candidate PDCCH monitoring.

3) And if at least one RE is overlapped between the resource allocated by the LTE common reference signal parameter (LTE-CRS-ToMatchAround) for rate matching and the resource allocated by the candidate PDCCH, the UE does not monitor the candidate PDCCH.

If the UE starts PDCCH candidate detection for the Type-0PDCCH CSS, the UE may consider that there is no SSB/PBCH transmission on the resource where the PDCCH candidate for the Type-0PDCCH CSS is located.

2. When the resources allocated to the candidate PDCCHs overlap, the following rules are defined:

for the case of single-cell and same-band carrier aggregation, if there is a Resource overlap between PDCCH monitoring opportunities of PDCCH candidates, the UE may detect only one Control Resource Set (core Set), or detect a core Set having the same quasi-co-site (QCL-type) characteristic among multiple core sets at the same time. The candidate PDCCH carrying the power saving signal can share CORESET with candidate PDCCHs carrying other signals.

3. When the resources allocated to the PDCCH candidates overlap with the resources allocated to the PDSCH, there are the following rules:

for a New air interface (New Radio,5G) in a 5G system, PDCCH multiplexing with PDSCH is supported.

In the prior art, in a 5G system, a base station needs to send a power saving signal to a UE during the operation of the UE, so that the UE switches the operation mode to save power. When the resources allocated to the power saving signal overlap with the resources allocated to other signals (for example, overlap with the resources where the existing physical layer channel is located, or overlap with the resources where the reference signal is located), how to transmit and detect the power saving signal is a problem that needs to be considered in a key way; the existing Physical layer Channel may be divided into three Physical channels, namely, a Synchronization Signal Block (SSB)/Physical Broadcast Channel (PBCH), a PDCCH, and a PDSCH.

If the UE follows the above specifications when detecting the power-saving signal, the UE will not perform power-saving signal detection when the resource allocated by the power-saving signal overlaps with the resource allocated by other signals.

In this case, on one hand, the use of the power-saving signal is limited, which leads to the waste of resources for bearing the power-saving signal; on the other hand, if the UE is thus woken up to perform PDCCH monitoring to receive the power saving signal, the power saving effect is not achieved, and if there is data transmission without waking up the UE, the performance of the UE is also lost.

For example, when the resources allocated to the PDCCH candidates carrying power saving signals overlap with the resources allocated to PDCCH candidates carrying other signals, due to different DRX starting points of different UEs, a situation may occur in which one UE is in a DRX inactive state while another UE is in a DRX active state, and then, if the power saving signals are transmitted for the UEs in the DRX inactive state and other signals are transmitted for the UEs in the DRX active state, interference to the power saving signals may be increased.

In view of the above, it is desirable to provide a new power-saving signal transmission method to overcome the above-mentioned drawbacks.

Detailed Description

In this embodiment of the present application, when a resource allocated to a power saving signal conflicts with other resources allocated to other signals, a terminal side may determine a receiving policy of the power saving signal according to a preset first criterion, and a base station side may determine a sending policy of the power saving signal according to a preset second criterion, where the first criterion and the second criterion may be the same or different, for example, the terminal side may preferentially receive the power saving signal and the base station side may preferentially send the power saving signal, and for example, the terminal side may preferentially receive the power saving signal and the base station side may preferentially send other signals instead of preferentially sending the power saving signal, and a specific operation is performed according to a local policy. Therefore, the resource utilization rate and the resource reliability of the power-saving signal can be effectively improved, and the power-saving effect of the terminal is ensured.

Preferred embodiments of the present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 2, in the embodiment of the present invention, a flow of receiving the power saving signal by the target terminal is as follows:

step 201: and the target terminal determines the signal transmission resource configuration information set by the base station side.

On the terminal side, based on the signal transmission resource configuration information set on the base station side, the target terminal can definitely know whether the resource configured for each terminal conflicts.

Step 202: and the target terminal determines a first resource allocated to the power saving signal of the target terminal based on the signal transmission resource configuration information, and determines a receiving strategy of the power saving signal according to a preset first criterion when the first resource conflicts with a first other resource allocated to other signals.

Optionally, the first other resource is any one of the following:

a1, a resource allocated to another physical layer transport channel of the target terminal, or a resource allocated to a reference signal of the target terminal.

A2, a resource allocated to a physical layer transport channel of another terminal, or a resource allocated to a reference signal of the another terminal.

Optionally, the first resource and the first other resource are resources configured for a same cell, that is, the target terminal and the other terminals may be terminals accessing the same cell.

Optionally, no matter the physical layer transport channels of the target terminal or the physical layer transport channels of other terminals, the physical layer transport channels include, but are not limited to, any of the following:

a broadcast channel (e.g., SSB/PBCH);

a random access channel (e.g., PRACH);

a control channel (e.g., PDCCH or PUCCH);

data shared channel (e.g., PDSCH or PUSCH).

Optionally, the reference signal includes, but is not limited to, any of the following:

demodulation Reference Signal (DMRS);

channel State Information Reference Signal (CSI-RS);

tracking reference signals (CSI-RS for tracking, TRS);

sounding Reference Signal (SRS);

the Phase Tracking Reference Signal (PT-RS).

Optionally, in the process of executing step 202, when determining that the first resource allocated by the power saving signal of the target terminal conflicts with the first other resource allocated by the other signal, the target terminal may adopt, but is not limited to, any one of the following manners or combinations:

determining that the first resource and the first other resource contain the same time slot or the same symbol, that is, a time domain resource collision occurs;

determining that the first resource and the first other resource contain the same RE, or the same Control Channel Element (CCE), or the same CORESET, or the same bandwidth subset (BWP); namely, frequency domain resource conflict occurs;

determining that the first resource and the first other resource are not consistent in a CORESET or an antenna port, or are not consistent in a Transmission Configuration Indication (TCI) state of a specified SSB, or are not consistent in an antenna port or a TCI state of a specified CSI-RS; namely, the spatial domain resource conflict occurs;

determining the first resource and the first other resource using the same scrambling sequence; i.e. a code domain collision occurs.

Optionally, the first criterion adopted by the target terminal may include, but is not limited to, any one or a combination of the following:

1) the power saving signal is not detected.

For example, the power saving signal is not detected as long as it is determined that there are overlapping resources (including all or part of collisions).

2) The power saving signal is preferentially detected, or only the power saving signal is detected.

For example, whenever it is determined that there are overlapping resources (including all or part of collisions), the power saving signal is received preferentially, or only.

3) The power saving signal is detected based on priority information set corresponding to a current scene.

According to different scenes, the target terminal can set a signal detection sequence according to different priority information, so that the target terminal needs to determine corresponding priority information according to the current scene, and then determines the sequencing according to which sequence to detect the power saving signal and other signals.

The priority information may refer to the power saving signal having the highest priority, or to other signals having the highest priority, or may be set with a priority order of the power saving signal and each of the other signals, and further, may include a scenario where only one of the signals is received according to the priority, which is not described herein again.

4) The power saving signal is detected based on priority information set in a unified manner for each scene.

Aiming at different scenes, the target terminal can set a signal detection sequence according to the uniform priority information, so that the target terminal can detect the power-saving signals and other signals according to corresponding sequencing only by acquiring the preset priority information.

Similarly, the priority information may refer to that the power saving signal has the highest priority, or that other signals have the highest priority, or that priority ordering of the power saving signal and each other signal is set, or further, a scenario in which only one of the signals is received according to the priority may be included, which is not described herein again.

5) Determining the occupation ratio of the conflicted resource in a specified resource range, and preferentially detecting the power saving signal or only detecting the power saving signal when the occupation ratio reaches a preset first occupation ratio threshold value; .

The specified resource range can be flexibly configured according to actual scenes.

For example, all the resources allocated to the target terminal may be used, or all the resources allocated to the cell in which the target terminal is located may be used.

For example, the resources may be all resources allocated to the other terminal, or all resources allocated to the cell in which the other terminal is located.

Also for example, it may be a minimum set of the first resource and the first other resource where the conflict occurs.

The above two configuration modes are only examples and are not described herein again.

6) The power saving signal and the other signal are detected simultaneously.

Here, the objects to receive the power saving signal and the other signals may be the target terminals, and are not limited herein.

In practical applications, although resource collision occurs, if no interference is caused between signals (e.g., the power saving signal and other signals are orthogonal signals to each other), the target terminal may detect the power saving signal and other signals simultaneously on the resource where the collision occurs. Alternatively, if the target terminal has full duplex capability, the target terminal may also receive and distinguish conflicting respective signals simultaneously.

Based on the foregoing embodiments, on the other hand, optionally, if DRX is configured, the occurrence time of the resource with collision may be within a DRX active period, or within a DRX inactive period, that is, may be at any time. If DRX is not configured, the time of occurrence of the resource with collision may be at any time.

Corresponding to the above embodiment, referring to fig. 3, in the embodiment of the present invention, a flow of transmitting the power saving signal by the base station is as follows:

step 301: and the base station determines the signal transmission resource configuration information set by the corresponding terminal side.

On the base station side, signal transmission resource configuration information set for each terminal is stored, and based on the signal transmission resource configuration information, the base station can definitely know whether a resource configured for each terminal conflicts.

Step 302: and the base station determines a second resource allocated to the power-saving signal of the target terminal based on the signal transmission resource configuration information, and determines a sending strategy of the power-saving signal according to a preset second criterion when the second resource conflicts with a second other resource allocated to other signals.

Optionally, the second other resource is any one of the following:

b1, a resource allocated to another physical layer transport channel of the target terminal, or a resource allocated to a reference signal of the target terminal.

B2, a resource allocated to a physical layer transport channel of another terminal, or a resource allocated to a reference signal of the another terminal.

Optionally, the second resource and the second other resource are resources configured for a same cell, that is, the target terminal and the other terminals may be terminals accessing the same cell.

Optionally, no matter the physical layer transport channel of the target terminal or the physical layer transport channel of the other terminal, the physical layer transport channel includes, but is not limited to, any one of the following:

a broadcast channel (e.g., SSB/PBCH);

random access channel (e.g., PRACH);

a control channel (e.g., PDCCH or PUCCH);

data shared channel (e.g., PDSCH or PUSCH).

DMRS；

CSI-RS；

TRS；

SRS；

PT-RS。

Optionally, in the process of executing step 302, when determining that the second resource allocated by the power-saving signal of the target terminal conflicts with the second other resource allocated by the other signal, the base station may adopt, but is not limited to, any one of the following manners or combinations:

determining that the second resource and the second other resource contain the same time slot or the same symbol, that is, a time domain resource collision occurs;

determining that the second resource and the second other resource contain the same RE, or the same CCE, or the same CORESET, or the same BWP; namely, frequency domain resource conflict occurs;

determining that the second resource and the second other resource are not consistent in the CORESET or the antenna port, or are not consistent in the specified SSB antenna port or TCI state, or are not consistent in the specified CSI-RS antenna port or TCI state; namely, the spatial domain resource conflict occurs;

determining the second resource and the second other resource using the same scrambling sequence; i.e. a code domain collision occurs.

Optionally, the second criterion used by the base station may include, but is not limited to, any one or a combination of the following:

1) the power saving signal is not transmitted.

For example, as long as it is determined that there are overlapping resources (including all or part of collisions), the power saving signal is not transmitted to the target terminal.

2) The power saving signal is preferentially transmitted, or only the power saving signal is transmitted.

For example, whenever it is determined that there are overlapping resources (including all or part of collisions), the power saving signal is preferentially transmitted to the target terminal, or only transmitted to the target terminal.

3) And transmitting the power saving signal based on priority information set corresponding to the current scene.

For different scenes, the base station sets a signal sending sequence according to different priority information, and therefore the base station needs to determine corresponding priority information according to the current scene so as to determine which sequence to send the power-saving signal and other signals.

The priority information may refer to the power saving signal having the highest priority, may also refer to other signals having the highest priority, and may also be a priority sequence of the power saving signal and each other signal, which is not described herein again.

4) And transmitting the power saving signal based on priority information uniformly set corresponding to each scene.

Aiming at different scenes, the base station sets the signal sending sequence according to the unified priority information, so that the base station can send the power-saving signal and other signals according to the corresponding sequence only by acquiring the preset priority information.

Similarly, the priority information may refer to the power saving signal having the highest priority, may refer to other signals having the highest priority, and may also refer to the priority sequence of the power saving signal and each other signal, which is not described herein again.

5) And determining the occupation ratio of the conflicted resource in the designated resource range, and preferentially sending the power saving signal when the occupation ratio reaches a preset second occupation ratio threshold value.

Also for example, it may be a minimum set of the second resource and the second other resource where the conflict occurs.

On the other hand, the values of the first and second occupation ratio thresholds may be the same or different, and may be flexibly set according to the actual application scenario, which is not described herein again.

6) The power saving signal and the other signal are transmitted simultaneously.

The transmission destination of the power saving signal and the other signals may be the target terminal, or may be the target terminal and the other terminals, and the present invention is not limited thereto.

In practical applications, although resource collision occurs, the base station may transmit the power-saving signal and the other signals at the same time if the signals do not interfere with each other (e.g., the power-saving signal and the other signals are orthogonal signals to each other). Alternatively, if the target terminal has full duplex capability, the target terminal may also receive and distinguish conflicting respective signals simultaneously.

On the other hand, optionally, if DRX is configured, the occurrence time of the resource with collision may be within a DRX active period, or may be within a DRX inactive period, that is, may be at any time. If DRX is not configured, the time of occurrence of the resource with collision may be located at any time.

Optionally, the contents of the first criterion and the second criterion may be the same or different, and the contents of the first criterion and the second criterion are only examples and are not limited to the contents described in the embodiments of the present invention, and may be flexibly set according to an application scenario in practice, and are not described herein again.

The following describes the application process of the first criterion and the second criterion in further detail with reference to the actual application scenario.

Since the contents of the first criterion and the second criterion may correspond to each other, in the following embodiments, in order to avoid content duplication, in one scenario, description will be performed from the perspective of the base station or the target terminal, and details will not be described later.

The application scene one: when the resource allocated by the power saving signal conflicts with the resource allocated by the SSB/PBCH, the detection method of the power saving signal is used.

Assuming that the UE configures DRX and configures a detection resource of the power saving signal when the UE detects the power saving signal before continuous monitoring (on-duration) during the DRX inactive period, and assuming that there is a partial or complete overlap between the resource allocated by the PDCCH candidate of the power saving signal and the resource allocated by the SSB, any one of the following manners or combinations may be specifically used when the UE detects the power saving signal.

Corresponding to the above criterion 1), as long as it is determined that there is resource overlap, the UE does not perform power saving signal detection, i.e., does not perform node signal reception.

Corresponding to the criterion 2), detecting the power saving signal on the detection resource configured corresponding to the power saving signal no matter how many overlapped resources are; in this case, the UE simultaneously performs the detection of the power saving signal and the reception of the SSB/PBCH.

Corresponding to the above criterion 2), the UE performs the detection of the power saving signal only on non-overlapping REs in the detection resources configured for the power saving signal.

Corresponding to the above criterion 4), the UE detects the power-saving signal according to preset priority information.

For example, in an awake state, the UE needs to receive the SSB/PBCH to ensure the service transmission performance, and at this time, the SSB/PBCH has the highest priority, so that the power-saving signal is not detected; and after the base station side indicates the UE to enter the dormant state through the power saving signal, the UE needs to re-arouse the data service reception according to the power saving signal received again, and at the moment, the priority of the power saving signal is higher than that of the SSB/PBCH.

After the UE is awakened, due to the SSB/PBCH missing the overlapping position, a synchronization System Information (SI) update is performed on the next SSB/PBCH.

Corresponding to the criterion 5), setting a certain overlap ratio threshold value, and detecting the power saving signal when the overlap ratio of the RE allocated to the power saving signal and the RE allocated to the SSB/PBCH is lower than the overlap ratio threshold value; and when the overlapping proportion of the RE allocated by the power saving signal and the RE allocated by the SSB/PBCH is not lower than the threshold value of the overlapping proportion, the detection of the power saving signal is not carried out.

Here, the resources for performing the power saving signal detection may be all the configured REs or non-overlapping REs.

The above criteria are merely illustrative and not limiting.

After receiving the power saving signal, the UE may determine the following content according to a display indication or a hidden indication of the power saving signal: whether to wake up for PDCCH monitoring, whether to adopt conventional PDCCH monitoring, whether to change the subsequent PDCCH monitoring behavior, or whether to execute other power-saving behaviors.

The above-described exemplary power saving behavior is not limited herein.

Application scenario two: and a method for detecting the power saving signal when the resource allocated to the power saving signal conflicts with the resource allocated to the other PDCCH.

In the embodiment of the present invention, a PDCCH type power saving signal is taken as an example for description.

It is assumed that there is a partial RE overlap between the CORESET associated with the search space where the power saving signal is located and the CORESET associated with other candidate PDCCHs configured for the CORESET by the base station, or all REs overlap, or two CORESETs are in a nested relationship.

It is also assumed that a CCE to which a PDCCH candidate for a power-save signal is assigned has a partial RE overlap with a CCE to which another PDCCH candidate is assigned, all REs overlap with each other, or two CCEs are in a nested relationship.

For the above cases, the priority information in different scenarios may be set corresponding to the above criterion 3.

(1) When the search space type associated with the PDCCH of the power saving signal is CSS, if the base station also configures a candidate PDCCH of the CSS type for the UE at the same time, so as to indicate whether the UE has data transmission, any one of the following manners or combinations may be specifically used to receive the power saving signal.

i. The priority of the power-save signal is lower than the priority of the candidate PDCCHs of other CSS types.

For example, if the PDCCH candidates of other CSS types are configured as the Type0-PDCCH CSS set or the Type0A-PDCCH CSS set, the UE preferentially receives the PDCCH candidates of other CSS types, and then receives the power-saving signal when the subsequent monitoring opportunity of the power-saving signal arrives.

ii. The priority of the power-save signal is higher than the priority of candidate PDCCHs of other CSS types.

For example, if the PDCCH candidates of other CSS types are configured as Type2-PDCCH CSS sets, that is, paging search space sets, the UE preferentially receives the power-saving signal without performing paging detection, and optionally, the UE may not perform subsequent PDCCH monitoring, thereby improving the power-saving performance of the terminal. Of course, the UE may also perform PDCCH monitoring at subsequent paging monitoring occasions.

And iii, the power-saving signal is consistent with the priority of the candidate PDCCHs of other CSS types.

For example, if the resources allocated to the candidate PDCCHs of other CSS types and the resources allocated to the core set of the power saving signal are of the same QCL-type D characteristics, the UE may receive the power saving signal and the other candidate PDCCHs at the same time.

The base station needs to ensure that the power-saving signal received by the UE is consistent with information carried by other PDCCH candidates.

(2) When the Search Space type associated with the PDCCH of the power saving signal is the CSS, if the base station also configures a UE-specific Search Space (USS) type PDCCH for the UE at the same time, to indicate whether the UE has data transmission, then any one of the following manners or combinations may be specifically used to receive the power saving signal.

i. The priority of the power save signal is higher than the priority of the candidate PDCCHs of other USS types.

Alternatively, the power saving signal may be a group level power saving signal for notifying power saving information of a group of UEs, and the UE preferentially receives the power saving signal to achieve a better power saving effect without monitoring an unnecessary PDCCH.

If the UE has data to receive, the UE may also know that the UE does not need to sleep, and monitor the USS type PDCCH candidate at a later monitoring occasion.

ii. The priority of the power saving signal is lower than the priority of the candidate PDCCHs of other USS types.

It is assumed that the UE currently has data transmission, for example, the data may not be completely transmitted, or the UE may be scheduled across time slots by the base station, but is configured with a group-level power saving signal by the base station.

Then, the UE can preferentially monitor the USS type PDCCH for carrying scheduling information without reception of the power-save signal.

The UE may perform reception of the power saving signal only when the UE completes data reception or determines that there is no cross-slot scheduling.

And iii, the power saving signal is consistent with the priority of the candidate PDCCHs of other USS types.

Under the condition of meeting the requirement of the blind detection times of the UE, if the power-saving signal and the CORESET resource where other candidate PDCCHs are located have the same QCL-type D characteristic, the UE can simultaneously receive the power-saving signal and other candidate PDCCHs.

(3) When the search space type associated with the PDCCH of the power saving signal is USS, if the base station also configures a candidate PDCCH of the USS type for the UE, where the power saving signal and the CORESET associated with the candidate PDCCH have the same or different QCL-type D characteristics, then any one of the following manners or combinations may be specifically used to receive the power saving signal.

i. The priority of the power save signal is higher than the priorities of the other PDCCH candidates.

Specifically, the UE does not monitor other PDCCH candidates as long as it receives the power saving signal. And when the power-saving signal indicates that the UE enters a dormant state, the UE does not perform subsequent PDCCH monitoring. And when the power-saving signal indicates that the UE enters an awake state, the UE carries out PDCCH monitoring at a subsequent monitoring opportunity.

ii. The priority of the power save signal is lower than the priorities of the other PDCCH candidates.

Specifically, the UE preferentially receives other PDCCH candidates and does not monitor the power-saving signal, so as to ensure correct data reception. The UE monitors the power-saving signal only at the non-conflicting monitoring opportunity.

This case requires the base station to configure the UE with a longer duration listening time or more listening occasions.

Under the condition of meeting the requirement of the blind detection times of the UE, if the power saving signal and the CORESET resource where other candidate PDCCHs are located have the same QCL-type D characteristic, the UE can simultaneously receive the power saving signal and the other candidate PDCCHs.

(4) When the search space type associated with the PDCCH of the power saving signal is USS, if the base station also configures a CSS type PDCCH candidate for the UE, the power saving signal may be received in any one of the following manners or combinations.

For example, if the power saving signal carries a system update message, the priority of the power saving signal may be higher than candidate PDCCHs of other CSS types. In this way, if the power saving signal collides with a PDCCH candidate of another CSS type, the UE preferentially receives the power saving signal.

Further, based on the above cases (1) - (4), if the information carried in the power saving signal conflicts with the information carried in other candidate PDCCHs, any one of the following processing methods may be adopted:

all are deleted;

the information carried by other candidate PDCCHs is taken as a standard;

the information carried by the power-saving signal is taken as the standard;

the information carried by the latest received power saving signal or the candidate PDCCH is taken as the standard.

In addition, the base station can also ensure that the power saving signal received by the UE is consistent with information carried by other candidate PDCCHs.

Application scenario three: and when the resource allocated by the power saving signal conflicts with the resource allocated by the PRACH, the detection method of the power saving signal.

The base station pre-configures PRACH for the UE so that the UE can initiate a random access process when uplink data arrives.

Correspondingly, when uplink data arrives, the UE may send a preamble sequence on the preconfigured PRACH, and if the power saving signal collides with the preamble sequence sent by the UE, the UE may refer to a situation that resource collision occurs with the SRS and configured in the subsequent application scenario five. And selecting to send a preamble sequence on the PRACH or receive the power-saving signal according to the duplex condition of the UE.

Specifically, the terminal may receive the power saving signal in any one or a combination of the following manners:

i. the preamble sequence has a higher priority than the power save signal.

Specifically, when the UE supports only uplink signal transmission or only downlink signal reception at the same time, the transmission priority of the uplink data of the UE is higher.

ii. If the UE is a full-duplex terminal, the SRS transmission and the power-saving signal reception are performed simultaneously.

And iii, the priority of the power saving signal is higher than that of the SRS.

Specifically, when the UE only supports uplink signal transmission or only supports downlink signal reception at the same time, the UE first receives the node signal to ensure that the UE achieves an optimal power saving effect.

And an application scene four: a method for detecting a power saving signal when a resource to which the power saving signal is allocated collides with a resource to which a data shared channel (e.g., PDSCH or PUSCH) is allocated.

Assuming that the base station can transmit the power-saving signal during the DRX activation period, and the resources allocated to the PDCCH can be multiplexed with the resources allocated to the PDSCH or PUSCH, the base station can avoid the resource collision of the power-saving signal and the data transmission for the same UE, but since the CORESET allocated to different UEs may be different, the resource collision of the PDCCH and the PDSCH may occur on the same resource. Once a collision occurs, interference occurs, thereby affecting the reception performance of both.

When the resource conflict occurs, the base station may transmit the power saving signal in the following manner:

i. the priority of the power saving signal is higher than the priority of the data transmission.

Specifically, if the base station sends the power saving signal on a certain time frequency resource, data transmission on the time frequency resource is avoided.

ii. The priority of the power saving signal coincides with the priority of the data transmission.

Accordingly, on the terminal side, the reception of the power saving signal can be performed by the reception performance of the terminal.

And iii, the priority of the power saving signal is lower than that of data transmission.

In this way, data transmission performance can be ensured.

Application scenario five: a method for detecting a power saving signal when a resource to which the power saving signal is allocated conflicts with a resource to which a reference signal is allocated.

(1) The resources to which the power-saving signals are allocated collide with the resources to which the CSI-RS is allocated.

Assuming that the base station has configured the UE with periodic or semi-persistent or aperiodic CSI-RS for channel quality measurement or synchronization (e.g., TRS), the power-saving signal may collide with CSI-RS transmission resources, and then the UE may specifically receive the power-saving signal in any one of the following manners or combinations.

i. The priority of the CSI-RS signal is higher than the priority of the power saving signal.

When the CSI-RS signal collides with the power saving signal, the UE only receives the CSI-RS.

In this case, the UE may receive the power saving signal again at the next power saving signal monitoring timing without receiving the resource with collision, or may receive the power saving signal on the resource without collision.

ii. The priority of the power saving signal is higher than that of the CSI-RS signal.

When the CSI-RS signal conflicts with the power saving signal, if the CSI-RS signal is periodic or semi-persistent, the UE preferentially receives the power saving signal, so that the UE achieves the optimal power saving effect.

And iii, the priority of the power saving signal is consistent with that of the CSI-RS signal.

That is, the UE receives the CSI-RS signal and the power saving signal at the same time.

For example, the base station may send the power-saving signal on other resources except for the pattern (pattern) to which the CSI-RS signal is allocated by using techniques such as rate matching, and accordingly, the UE may receive the two signals on the same resource or on a part of the resource where there is a collision, and perform resource separation on the power-saving signal according to the pattern of the CSI-RS signal, so as to implement demodulation and decoding of the two different signals.

(2) The resources to which the power saving signal is allocated collide with the resources to which the SRS is allocated.

Specifically, if the UE does not configure an uplink channel (e.g., PUSCH or PUCCH), when an SRS transmitted by the UE collides with the power saving signal in the time domain, the UE may specifically receive the power saving signal in any one of the following manners or combinations.

i. The SRS signal has a higher priority than the power saving signal.

Therefore, the UE can be ensured to only support the transmission of the uplink signal or only support the reception of the downlink signal in the same time.

ii. If the UE is a full-duplex terminal, the SRS transmission and the power saving signal reception are performed simultaneously,

and iii, the priority of the power saving signal is higher than that of the SRS signal.

Thus, the UE can be ensured to achieve the optimal power saving effect.

Specifically, if the UE has configured an uplink channel (e.g., PUSCH or PUCCH) and configured a periodic SRS, a semi-persistent SRS, or an aperiodic SRS, the UE may further receive the power saving signal by using any one of the following manners or combinations.

i. The SRS signal has a higher priority than the power saving signal.

Specifically, if the UE supports only uplink signal transmission or only downlink signal reception at the same time, in this case, the base station may configure multiple times of power saving signal monitoring opportunities for the UE in order to ensure reception of the power saving signal.

ii. The SRS and the power-saving signal can be simultaneously transmitted and received, if the terminal is a full-duplex terminal;

and iii, the priority of the power saving signal can be higher than that of the SRS signal, and particularly for the configuration of the periodic SRS or the semi-continuous SRS, the terminal can perform SRS transmission again at the next SRS transmission opportunity.

(3) The resources to which the power saving signals are allocated collide with the resources to which the DMRS is allocated.

DMRS is mainly used for downlink physical channel estimation, such as PDCCH, PDSCH or PBCH, and different downlink physical channels use corresponding reference signal patterns.

In the embodiment of the present invention, a PDCCH type power saving signal is taken as an example for explanation

The resources allocated to the PDCCH may be multiplexed with the resources allocated to the PDSCH or PUSCH, and thus the power saving signal may collide with the DMRS received through other candidate PDCCHs, may collide with the DMRS received through the PDSCH, and may collide with the DMRS received through the PBCH.

For the situation that resource conflict occurs with the DMRS received by using other candidate PDCCHs, reference may be made to the application scenario two described above, which is not described herein again.

For the situation of resource conflict with the DMRS received by using the PDSCH, refer to the application scenario four described above, and are not described herein again.

For the situation where resource conflict occurs with the DMRS for PBCH reception, refer to the first application scenario, which is not described herein again.

Application scenario six: the UE carries out priority sequencing on different Radio Network Temporary Identities (RNTIs) so as to realize the detection of the power-saving signal.

Under different search space types, the UE distinguishes different RNTIs:

for example: the Power-Saving radio network temporary identifier (Power Saving RNTI, PS-RNTI) vs Cell radio network temporary identifier (Cell RNTI, C-RNTI).

Another example is: PS-RNTI vs. System Information radio network temporary identity (System Information, RNTI, SI-RNTI).

Another example is: PS-RNTI vs. Random Access radio network temporary identity (RA-RNTI).

Another example is: paging radio network temporary identity (Paging RNTI, P-RNTI).

The UE may generate corresponding priority information for each type of RNTI configured by the base station, so as to ensure the receiving performance of a certain candidate PDCCH.

For example, the priority information may be set to: SI-RNTI RA-RNTI P-RNTI PS-RNTI C-RNTI.

The above description is merely illustrative of priority information and is not the only priority information.

An application scene seven: and when the resources allocated to the power saving signals of the UE conflict with the resources allocated to the PDCCHs of other UEs in the same cell, the base station transmits the power saving signals.

Since the DRX parameter configurations of different UEs may be different in the same cell, the starting points of the DRX active periods of different UEs may be different, and thus, when one UE is in the DRX inactive state, another UE is in the DRX active state may occur. Obviously, the power saving signal of the UE in the DRX inactive state may collide with the PDCCH of the UE in the DRX active state, which may increase interference to the power saving signal.

Since the PDCCH monitoring period of the UE in the DRX active state is usually relatively complicated (e.g. 1 timeslot), and the power saving signal monitoring period of the UE in the DRX inactive state is relatively long (e.g. one DRX cycle), in order to achieve better performance of receiving the power saving signal, the base station may configure a certain monitoring priority to enable the UE in the DRX active state to avoid the PDCCH monitoring periods of other UEs, so as to ensure the correct detection of the power saving signal by the UE in the DRX inactive state.

An application scenario eight: when the UE determines that the power saving signal has a resource conflict with another signal (e.g., another channel or a reference signal), if the UE determines that the first criterion indicates not to detect the power saving signal, the UE needs to determine whether to perform a conventional DRX operation, or whether to perform a conventional channel or signal reception, or whether to continue to sleep when determining a reception strategy of the power saving signal.

(1) If the UE determines the signal transmission resource configuration information, indicating that each listening period of the power-saving signal contains 1 listening opportunity (e.g., duration in the search space of the power-saving signal is set to 1, and one listening opportunity contains 1 timeslot), the UE may perform, but is not limited to, any one or a combination of the following operations.

i. And the UE executes subsequent power saving operation according to the method configured by the base station side.

For example, if the base station side is configured as follows: if the UE does not successfully detect the power saving signal, the UE sleeps; the UE enters a sleep state when determining not to detect the power saving signal.

For another example, if the base station side is configured as follows: if the UE fails to successfully detect the power-saving signal, performing a conventional DRX operation, or performing a conventional channel or signal reception; the UE performs a conventional DRX operation or performs a conventional channel or signal reception when it is determined that the power saving signal is not detected.

ii. The UE enters a sleep state.

iii, the UE performs a conventional DRX operation, or performs a conventional channel or signal reception.

And iiii, keeping the current state of the UE unchanged.

For example, if the UE is currently in a sleep state, the UE maintains the sleep state.

For example, if the UE is currently performing a normal DRX operation or performing a normal channel or signal reception, the UE maintains performing the normal DRX operation or performing the normal channel or signal reception.

(2) If the UE determines the signal transmission resource configuration information and indicates that each listening period of the power saving signal includes multiple listening occasions (e.g., duration in the search space of the power saving signal is set to 2, where one listening occasion includes 1 timeslot, that is, there are 2 listening occasions in total), the UE may perform, but is not limited to, any one of the following operations or combinations, and optionally, the base station may possibly transmit the power saving signal at each listening occasion.

i. If the UE determines that the resource conflict does not occur at the first monitoring opportunity in one power saving signal monitoring period, the UE detects the power saving signal at a subsequent monitoring opportunity of the monitoring opportunity where the resource conflict occurs in the one power saving signal monitoring period, or does not detect the power saving signal.

ii. If the UE determines that the resource conflict occurs at the first monitoring opportunity in a node signal monitoring period, the UE detects the power-saving signal at a subsequent monitoring opportunity of the monitoring opportunity where the resource conflict occurs in the node signal monitoring period.

For the case that the UE has multiple monitoring occasions in one node signal monitoring period, if the UE has detected the power saving signal in one monitoring occasion, the power saving signal may be detected or may not be detected at other monitoring occasions in the one node signal monitoring period.

After receiving the power-saving signal, the UE determines whether to perform a conventional DRX operation subsequently, or whether to perform a conventional channel or signal reception, or to continue to maintain a sleep state according to the indication of the power-saving signal.

If the UE does not detect the power saving signal in each power saving signal monitoring period, the UE continues to detect the power saving signal at a subsequent monitoring occasion, or performs a corresponding operation based on a method configured by the base station, or directly enters a sleep state, or performs a conventional DRX operation, or performs a conventional channel or signal reception, or maintains a current state unchanged.

Note: the parameters configured for the base station are only for illustration here.

Application scenario nine: when the base station determines that the power saving signal has resource conflict with other signals (e.g., other channels or reference signals), if the base station determines that the second criterion indicates not to transmit the power saving signal, the base station may specifically, but not limited to, determine the transmission strategy of the power saving signal.

(1) If the base station determines the signal transmission resource configuration information and indicates that each power saving signal monitoring period of the UE includes 1 monitoring opportunity (e.g., duration in the search space of the power saving signal is set to 1, and one monitoring opportunity includes 1 timeslot), the base station does not transmit the power saving signal.

(2) If the base station determines the signal transmission resource configuration information, which indicates that each power-saving signal monitoring period of the UE includes multiple monitoring occasions (e.g., duration in the search space of the power-saving signal is set to 2, where one monitoring occasion includes 1 timeslot, that is, there are 2 monitoring occasions in total), the base station may perform any one of the following operations.

i. If the base station determines that the resource conflict between the node signal and other signals does not occur at the first monitoring time in a node signal monitoring period, the base station transmits the power-saving signal at the first monitoring time, and transmits the power-saving signal at a subsequent monitoring time of the monitoring time at which the resource conflict occurs or does not transmit the power-saving signal in the node signal monitoring period.

ii. If the base station determines that the resource conflict between the power-saving signal and other signals occurs at the first monitoring time in a node signal monitoring period, the base station transmits the power-saving signal at the subsequent monitoring time of the monitoring time at which the resource conflict occurs in the node signal monitoring period.

The parameters configured by the base station in the above embodiments are only examples.
