Description

A power-saving signal transmission method, terminal, base station and storage medium

The invention belongs to the field of communications, and in particular relates to a power-saving signal transmission method, terminal, base station and storage medium.

In the 5G system, based on the mobility of the User Equipment (UE), the processes that are often triggered during the use of the UE include but are not limited to the random access process and the paging process.

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

When the UE is configured with Discontinuous Reception (DRX), the UE will monitor the PDCCH discontinuously. The UE only monitors the PDCCH during the DRX startup period (that is, DRX on duration) or when the inactivity timer (Inactivity timer) has not expired.

Referring to Figure 1, during the DRX cycle, the UE only monitors the PDCCH during the On duration cycle. During the DRX opportunity (Opportunity for DRX), that is, during the DRX off time, the UE does not receive other PDCCHs except scheduling broadcast signaling. Reduce power consumption, i.e. enter sleep state.

The Rel-15 standard protocol TR38.213 stipulates that the following regulations exist when configuring resources between different physical channels.

1. When the resources allocated to the candidate PDCCH overlap with the resources allocated to the synchronization signal block (SynchronizationSignalBlock, SSB)/physical broadcast channel (Physical Broadcast Channel, PBCH), there are the following regulations: If the UE has not started candidate PDCCH detection in the Type-0 PDCCH Common Search Space (CSS), the UE will not perform candidate PDCCH detection when the following resource collisions exist: 1) If at least one resource element (Resource Element, RE) overlaps between the resources allocated to the candidate PDCCH of the Type-0 PDCCH CSS and the resources allocated to the SSB/PBCH configured in the SIB1 message, then the UE will not Perform candidate PDCCH monitoring; 2) If at least one RE overlaps between the resources allocated to the candidate PDCCH of the Type-0 PDCCH CSS and the resources allocated to the SSB/PBCH configured in the serving cell's common information (Serving Cell Config Common), then the UE Candidate PDCCH monitoring will not be performed; 3) If there is at least one RE overlap between the resources allocated by the LTE common reference signal parameter (lte-CRS-ToMatchAround) used for rate matching and the resources allocated by the candidate PDCCH, then the UE does not monitor the candidate PDCCH; If the UE starts detection of the candidate PDCCH of the Type-0 PDCCH CSS, the UE may consider that there is no SSB/PBCH transmission on the resource where the candidate PDCCH of the Type-0 PDCCH CSS is located.

2. When the resources allocated between candidate PDCCHs overlap, the following regulations apply: In the case of carrier aggregation in a single cell and in the same frequency band, if there is resource overlap between the PDCCH monitoring opportunities of the candidate PDCCH, the UE can only detect one control resource set (CORESET), or, in multiple CORESETs with the same quasi-cosite address (QCL-TypeD) characteristics are simultaneously detected in CORESET. Candidate PDCCHs carrying power saving signals can share CORESET with candidate PDCCHs carrying other signals.

3. When the resources allocated to the candidate PDCCH overlap with the resources allocated to the PDSCH, the following regulations apply: For the new air interface (New Radio, 5G) in the 5G system, PDCCH and PDSCH multiplexing is supported.

Under the existing technology, in the 5G system, the base station needs to send a power saving signal to the UE during the operation of the UE, so that the UE switches the working 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 of the existing physical layer channel, or overlap with the resources of the reference signal), how to send and detect the power-saving signal? , is an issue that needs important consideration. Among them, existing physical layer channels can be divided into three physical channels: SSB/PBCH, PDCCH and PDSCH.

If the UE follows the above regulations when detecting the power saving signal, then when the resources allocated to the power saving signal overlap with the resources allocated to other signals, the UE will not detect the power saving signal.

In this case, on the one hand, the use of the power saving signal is restricted, resulting in a waste of resources carrying the power saving signal; on the other hand, if the UE is awakened to perform PDCCH monitoring to receive the power saving signal, the power saving effect will not be achieved, and if Failure to wake up the UE during data transmission will also cause loss of UE performance.

For example, when the resources allocated to the candidate PDCCH carrying the power saving signal overlap with the resources allocated to the candidate PDCCH carrying other signals, due to different DRX starting points of different UEs, a UE will be in the DRX non-activated state. At the same time, if another UE is in the DRX enabled state, then if a power saving signal is sent to the UE in the DRX non-activated state, and other signals are sent to the UE in the DRX enabled state, interference to the power saving signal will be increased.

In view of this, it is necessary to provide a new power-saving signal transmission method to overcome the above defects.

Referring to Figure 2, in the embodiment of the present invention, the process of the target terminal receiving the power saving signal is as follows: Step 201: The target terminal determines the signal transmission resource configuration information set on 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 clearly know whether the resources configured for each terminal conflict.

Step 202: Based on the signal transmission resource configuration information, the target terminal determines the first resource allocated to the power saving signal of the target terminal. When there is a conflict with the first other resource allocated to other signals, the target terminal determines according to the preset first criterion. The power saving signal reception strategy.

Optionally, the first other resource is any of the following: A1. Resources allocated to other physical layer transmission channels of the target terminal, or resources allocated to the reference signal of the target terminal; A2. The resources allocated to the physical layer transmission channels of other terminals, or the resources allocated to the reference signals of the other terminals.

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

Optional, whether it is other physical layer transmission channels of the target terminal or physical layer transmission channels of other terminals, the above physical layer transmission channels include but are not limited to any of the following: Broadcast channel (e.g., SSB/PBCH); Random access channel (e.g., PRACH); Control channel (e.g., PDCCH or PUCCH); Data sharing channel (eg, PDSCH or PUSCH).

Optionally, the above-mentioned first criterion adopted by the target terminal may include 1) not detecting the power saving signal, or may be but not limited to any one or combination of the following 2) to 6).

1) The power saving signal is not detected.

For example, whenever it is determined that there are overlapping resources (containing full or partial conflicts), the power save signal is not detected.

2) Prioritize detection of the power saving signal, or only detect the power saving signal.

For example, as long as it is determined that there are overlapping resources (including all conflicts or partial conflicts), the power saving signal is received first, or only the power saving signal is received.

3) Detect the power saving signal based on the priority information corresponding to the current scene setting.

For different scenarios, the target terminal will set the signal detection order according to different priority information. Therefore, the target terminal needs to determine the corresponding priority information according to the current scenario, so as to decide in which order to detect the power saving signal and other signals. .

The above priority information may refer to the highest priority of the power-saving signal, or may refer to the highest priority of other signals, or it may set the priority order of the power-saving signal and each other signal. Further, it may also include the following: The scenario of receiving only one of the signals in priority order will not be described again here.

4) Detect the power saving signal based on the priority information set uniformly for each scene.

For different scenarios, the target terminal will set the signal detection order according to the unified priority information. Therefore, the target terminal only needs to obtain the preset priority information, and then it can detect the power saving signal and other signals according to the corresponding order.

In the same way, the above priority information may refer to the highest priority of the power saving signal, or may refer to the highest priority of other signals, or it may set the priority order of the power saving signal and each other signal. Furthermore, This may include a scenario in which only one of the signals is received in order of priority, which will not be described again here.

5) Determine the proportion of the conflicting resource within the specified resource range. When reaching the preset first proportion threshold, the power saving signal is detected first, or only the power saving signal is detected.

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

For example, it may be all resources allocated to the target terminal, or all resources allocated to the cell where the target terminal is located.

For another example, it may be all resources allocated to other terminals, or all resources allocated to cells where other terminals are located.

For another example, it may also be the minimum set of the conflicting first resource and the first other resource.

The above two configuration methods are only examples and will not be described again here.

6) Detect the power saving signal and the other signals at the same time.

Wherein, the receiving object of the power saving signal and the other signals may both be the target terminal, which is not limited here.

In actual applications, although resource conflicts occur, if there is no interference between signals (for example, the power saving signal and other signals are orthogonal signals), the target terminal can detect the power saving signal and the power saving signal simultaneously on the conflicting resources. other signals. Alternatively, if the target terminal has full-duplex capabilities, the target terminal can simultaneously receive and differentiate between conflicting signals.

Based on the above embodiment, on the other hand, optionally, if DRX has been configured, the time of occurrence of the conflicting resource can be within the DRX startup period or within the DRX non-startup period, that is, it can be anywhere moment. If DRX is not configured, the conflicting resource can occur at any time.

Corresponding to the above embodiment, as shown in Figure 3, in the embodiment of the present invention, the process of the base station sending the power saving signal is as follows: Step 301: The base station determines the signal transmission resource configuration information set on the terminal side.

On the base station side, signal transmission resource configuration information set for each terminal is stored. Based on the signal transmission resource configuration information, the base station can clearly know whether the resources configured for each terminal conflict.

Step 302: Based on the signal transmission resource configuration information, the base station determines the second resource allocated to the power saving signal of the target terminal. When it conflicts with the second other resources allocated to other signals, the base station determines the second resource allocated to the target terminal according to the preset second criterion. Power saving signal sending strategy.

Optionally, the second other resource is any of the following: B1. Resources allocated to other physical layer transmission channels of the target terminal, or resources allocated to the reference signal of the target terminal; B2. Resources allocated to the physical layer transmission channels of other terminals, or resources allocated to the reference signals of the other terminals.

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

Optional, whether it is other physical layer transmission channels of the target terminal or physical layer transmission channels of other terminals, the above physical layer transmission channels include but are not limited to any of the following: Broadcast channel (e.g., SSB/PBCH); Random access channel (e.g., PRACH); Control channel (e.g., PDCCH or PUCCH); Data sharing channel (eg, PDSCH or PUSCH).

Optionally, the above reference signals include but are not limited to any of the following: DMRS; CSI-RS; TRS; SRS; PT-RS.

Optionally, the resources allocated to the physical layer transmission channel are any one or combination of the following: time domain resources, frequency domain resources, air domain resources, and code domain resources; The resources allocated to the reference signal are any one or combination of the following: time domain resources, frequency domain resources, air domain resources, and code domain resources.

Optionally, during the execution of step 302, when it is determined that the second resource allocated to the power saving signal of the target terminal conflicts with the second other resources allocated to other signals, the base station may adopt but is not limited to any of the following methods: or combination: It is determined that the second resource and the second other resource include the same time slot or the same symbol, that is, a time domain resource conflict occurs; Determine that the second resource and the second other resource include the same RE, or the same CCE, or the same CORESET, or the same BWP; that is, a frequency domain resource conflict occurs; Determine that the CORESET or antenna port where the second resource and the second other resource are located are inconsistent, or are inconsistent with the antenna port or TCI status of the designated SSB, or are inconsistent with the antenna port or TCI status of the designated CSI-RS; That is, an airspace resource conflict occurs; It is determined that the second resource and the second other resource use the same scrambling sequence; that is, a code domain conflict occurs.

Optionally, the above-mentioned second criterion adopted by the base station may include but is not limited to any one or combination of the following contents.

1) Do not send this power saving signal.

For example, as long as it is determined that there are overlapping resources (including full or partial conflicts), the power saving signal will not be sent to the target terminal.

2) Send the power saving signal first, or only send the power saving signal.

For example, as long as it is determined that there are overlapping resources (including all conflicts or partial conflicts), the power saving signal is sent to the target terminal first, or the power saving signal is sent only to the target terminal.

3) Based on the priority information corresponding to the current scene setting, the power saving signal is sent.

For different scenarios, the base station will set the signal sending order according to different priority information. Therefore, the base station needs to determine the corresponding priority information according to the current scenario, so as to decide in which order to send power saving signals and other signals.

The above priority information may mean that the power saving signal has the highest priority, or it may mean that other signals have the highest priority, or it may mean that the priority order of the power saving signal and each other signal is set, which will not be described again here.

4) The power saving signal is sent based on the priority information set uniformly corresponding to each scene.

For different scenarios, the base station will set the signal sending order according to the unified priority information. Therefore, the base station only needs to obtain the preset priority information, and then it can send power saving signals and other signals according to the corresponding order.

Similarly, the above priority information may refer to the power saving signal having the highest priority, or other signals having the highest priority, or the priority order of the power saving signal and other signals being set, which will not be described in detail here. .

5) Determine the proportion of the conflicting resource within the specified resource range. When the preset second proportion threshold is reached, the power saving signal is sent first.

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

For example, it may be all resources allocated to the target terminal, or all resources allocated to the cell where the target terminal is located.

For another example, it may be all resources allocated to other terminals, or all resources allocated to cells where other terminals are located.

For another example, it may also be the minimum set of the conflicting second resource and the second other resource.

The above two configuration methods are only examples and will not be described again here.

On the other hand, the values of the above-mentioned first proportion threshold value and the second proportion threshold value may be the same or different, and can be flexibly set according to the actual application scenario, and will not be described again here.

6) Send the power saving signal and the other signals at the same time.

The sending objects of the power saving signal and the other signals may both be the target terminal, or may be the target terminal and other terminals, which is not limited here.

In actual applications, although resource conflicts occur, if there is no interference between signals (for example, the power saving signal and other signals are orthogonal signals), the base station can send the power saving signal and other signals at the same time. Alternatively, if the target terminal has full-duplex capabilities, the target terminal can simultaneously receive and differentiate between conflicting signals.

On the other hand, optionally, if DRX has been configured, the time of occurrence of the conflicting resource can be within the DRX activation period or the DRX non-activation period, that is, it can be at any time. If DRX is not configured, the conflicting resource can occur at any time.

Optionally, the contents of the above-mentioned first criterion and the second criterion may be the same or different, and the contents of the above-mentioned first criterion and the second criterion are only examples and are not limited to the contents recorded in the embodiments of the present invention. In practice, it can be flexibly set according to the application scenario, so I won’t go into details here.

The following is a further detailed introduction to the application process of the above first and second criteria based on actual application scenarios.

Since the content of the first criterion and the second criterion may correspond, in subsequent embodiments, in order to avoid duplication of content, in one scenario, the description will be made from the perspective of the base station or the target terminal, which will not be described again.

Application scenario 1: When the resources allocated to the power saving signal conflict with the resources allocated to the SSB/PBCH, the detection method of the power saving signal.

Assume that the UE is configured with DRX, and during the DRX non-activation period, when the UE detects the power-saving signal before continuous monitoring (on-duration), it configures the detection resources of the power-saving signal. It is assumed that the resources allocated to the candidate PDCCH of the power-saving signal are the same as those of the SSB If there are partial RE overlaps or complete overlaps among the allocated resources, then when the UE detects the power saving signal, any one of the following methods or combinations can be used.

Corresponding to the above criterion 1), as long as it is determined that there is resource overlap, the UE will not detect the power saving signal, that is, it will not receive the power saving signal.

Corresponding to the above criterion 2), no matter how many overlapping resources there are, the power saving signal is detected on the detection resource configured corresponding to the power saving signal; at this time, the UE will detect the power saving signal and receive SSB/PBCH at the same time.

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

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

For example, when the UE is in the wake-up state, it needs to receive SSB/PBCH to ensure service transmission performance. At this time, SSB/PBCH has the highest priority, so the power-saving signal is not detected; and when the base station instructs the UE to enter the sleep state through the power-saving signal Afterwards, the UE needs to resume data service reception based on the power-saving signal received again. At this time, the priority of the power-saving signal is higher than that of SSB/PBCH.

After the UE wakes up, due to missing the overlapping SSB/PBCH, the UE will synchronize the system information (System Information, SI) update on the next SSB/PBCH.

Corresponding to the above criterion 5), set a certain overlap ratio threshold. When the overlap ratio between the RE allocated to the power saving signal and the RE allocated to the SSB/PBCH is lower than the above overlap ratio threshold, the power saving signal is detected; when When the overlap ratio between the RE allocated to the power saving signal and the RE allocated to the SSB/PBCH is not lower than the above overlap ratio threshold, the power saving signal will not be detected.

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

The above guidelines are examples only and are not intended to be limiting.

When the UE receives the power saving signal, it can determine the following based on the display indication or implicit indication of the power saving signal: whether to wake up for PDCCH monitoring, or whether to use conventional PDCCH monitoring, or whether to change subsequent PDCCH monitoring behavior. Or, whether to perform other power-saving actions.

This is not limited to the power-saving behavior illustrated above.

Application scenario two: When the resources allocated to the power saving signal conflict with the resources allocated to other PDCCHs, the detection method of the power saving signal.

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

It is assumed that there is 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 by the base station, or all REs overlap, or the two CORESETs are in a nested relationship.

It is also assumed that there is partial RE overlap between the CCE to which the candidate PDCCH of the power saving signal is allocated and the CCE to which other candidate PDCCHs are allocated, or all REs overlap, or the two CCEs are in a nested relationship.

For the above situations, the priority information in different scenarios can be set according 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 CSS type candidate PDCCH for the UE to indicate whether the UE has data transmission, then any of the following methods can be used: Or combined to receive power saving signals.

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

For example, if the candidate PDCCHs of other CSS types are configured as Type0-PDCCH CSS set or Type0A-PDCCH CSS set, the UE will receive the candidate PDCCHs of other CSS types first, and then receive the power saving signal when the subsequent power saving signal monitoring time arrives. .

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

For example, if the candidate PDCCH of other CSS types is configured as the Type2-PDCCH CSS set, that is, the search space set for paging, the UE will receive the power saving signal first without performing paging detection. Optionally, the UE may not perform subsequent PDCCH monitoring. , thereby improving the terminal’s power saving performance. Of course, the UE can also monitor the PDCCH at subsequent paging monitoring opportunities.

iii. The priority order of the power saving signal is consistent with that of candidate PDCCHs of other CSS types.

For example, if the resources allocated to other CSS-type PDCCH candidates and the CORESET of the power-saving signal have the same QCL-type D characteristics, the UE can receive the power-saving signal and 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 the information carried by other candidate PDCCHs.

(2) 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 UE-specific search space (UE-specific Search Space, USS) type for the UE, it is used to indicate whether the UE has Data transmission, then, specifically, any one or combination of the following methods can be used to receive power-saving signals.

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

Optionally, the power-saving signal may be a group-level power-saving signal, used to notify a group of UEs of power-saving information. UEs that receive power-saving signals preferentially can achieve better power-saving effects without monitoring unnecessary PDCCHs.

If the UE has data to receive, the UE can also learn that it does not need to sleep and monitor the USS type candidate PDCCH at the subsequent monitoring opportunity.

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

Assume that the UE is currently transmitting data. For example, the data may not be completely transmitted, or it may be scheduled by the base station across time slots, but at the same time, the base station configures a group-level power saving signal.

Then, the UE can preferentially monitor the USS type PDCCH used to carry scheduling information without receiving the power saving signal.

When the UE completes data reception or determines that there is no cross-time slot scheduling, the UE can receive the power saving signal.

iii. The priority order of the power saving signal is consistent with that of candidate PDCCHs of other USS types.

Under the condition that the UE blind detection number requirements are met, if the power saving signal and the CORESET resource where other candidate PDCCHs are located have the same QCL-type D characteristics, the UE can receive the power saving signal and other candidate PDCCHs at the same time.

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

i. The priority of the power saving signal is higher than that of other candidate PDCCHs.

Specifically, as long as the UE receives the power saving signal, it will not monitor other candidate PDCCHs.

When the power saving signal indicates that the UE enters the sleep state, the UE does not perform subsequent PDCCH monitoring. When the power saving signal indicates that the UE enters the awake state, the UE monitors the PDCCH at subsequent monitoring opportunities.

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

Specifically, the UE gives priority to receiving other candidate PDCCHs and does not monitor power saving signals to ensure correct reception of data. The UE can only monitor the power saving signal at non-conflicting monitoring opportunities.

This situation requires the base station to configure a longer continuous listening time or more listening opportunities for the UE.

iii. The priority order of the power saving signal is consistent with that of candidate PDCCHs of other USS types.

Under the condition that the UE blind detection number requirements are met, if the power saving signal and the CORESET resource where other candidate PDCCHs are located have the same QCL-type D characteristics, the UE can receive the power saving signal and other candidate PDCCHs at the same time.

(4) When the search space type associated with the PDCCH of the power-saving signal is USS, and if the base station also configures a CSS-type candidate PDCCH for the UE, then any one of the following methods or combinations can be used to receive the power-saving signal.

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

For example, if the candidate PDCCHs of other CSS types are configured as Type0-PDCCH CSS set or Type0A-PDCCH CSS set, the UE will receive the candidate PDCCHs of other CSS types first, and then receive the power saving signal when the subsequent power saving signal monitoring time arrives. .

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

For example, if the power saving signal carries a system update message, the priority of the power saving signal may be higher than that of other CSS type candidate PDCCHs. In this way, if a resource conflict occurs between the power saving signal and candidate PDCCHs of other CSS types, the UE receives the power saving signal first.

iii. The priority order of the power saving signal is consistent with that of candidate PDCCHs of other CSS types.

Under the condition that the UE blind detection number requirements are met, if the power saving signal and the CORESET resource where other candidate PDCCHs are located have the same QCL-type D characteristics, the UE can receive the power saving signal and other candidate PDCCHs at the same time.

Furthermore, based on the above situations (1)-(4), if the information carried in the power saving signal conflicts with the information carried by other candidate PDCCHs, any of the following processing methods can be used: Delete all; The information carried by other candidate PDCCH shall prevail; The information carried by the power saving signal shall prevail; The latest received power saving signal or the information carried by the candidate PDCCH shall prevail.

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

Application scenario three: When the resources allocated to the power-saving signal conflict with the resources allocated to the PRACH, the detection method of the power-saving signal.

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

The base station will pre-configure 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 will send the preamble sequence on the preconfigured PRACH. If the power saving signal conflicts with the preamble sequence sent by the UE, then you can refer to the resource conflict with SRS configured in subsequent application scenario 5. handle the situation. You can also choose to send the preamble sequence on the PRACH or receive the power saving signal according to the UE duplex situation.

Specifically, the terminal can receive the power saving signal in any one or combination of the following methods.

i. The priority of the preamble sequence is higher than the priority of the power saving signal.

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

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

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

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

Application scenario four: When the resources allocated to the power-saving signal conflict with the resources allocated to the data sharing channel (such as PDSCH or PUSCH), the detection method of the power-saving signal.

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

Assuming that the base station can send power saving signals during the DRX startup period, and the resources allocated to PDCCH can be multiplexed with the resources allocated to PDSCH or PUSCH, then, for the same UE, the base station can avoid resources for power saving signals and data transmission. However, since different UEs may be assigned different CORESETs, resource conflicts between PDCCH and PDSCH may occur on the same resources. Once a conflict occurs, interference will occur, thus affecting the reception performance of both.

When the above resource conflict occurs, the base station can send the power saving signal in the following manner.

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

Specifically, if the base station sends a power saving signal on a certain time-frequency resource, it avoids transmitting data on the time-frequency resource.

ii. The priority order of power saving signals is consistent with the priority order of data transmission.

Correspondingly, on the terminal side, the power saving signal can be received through the reception performance of the terminal.

iii. The priority of the power saving signal is lower than the priority of data transmission.

In this way, data transmission performance can be guaranteed.

Application scenario five: When the resources allocated to the power-saving signal conflict with the resources allocated to the reference signal, the detection method of the power-saving signal.

(1) The resources allocated to the power-saving signal conflict with the resources allocated to the CSI-RS.

Assuming that the base station has configured periodic, semi-persistent or aperiodic CSI-RS for the UE for channel quality measurement or synchronization (such as TRS), the power saving signal may conflict with the CSI-RS transmission resources, then, Specifically, the UE may use any one or combination of the following methods to receive the power saving signal.

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

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

In this case, the UE does not receive the power saving signal on the conflicting resource. It can receive the power saving signal at the next power saving signal monitoring opportunity, or it can receive the power saving signal on the resource where the conflict does not occur.

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 is periodic or semi-persistent, the UE will receive the power saving signal first, so that the UE can achieve the optimal power saving effect.

iii. The priority order of the power saving signal is consistent with the priority order 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 can use rate matching and other technologies to send power-saving signals on other resources outside the pattern to which the CSI-RS signal is allocated. Correspondingly, the UE can use the same resources or some resources with conflicts. The two signals are received at the same time, and the resources of the power-saving signal are separated according to the pattern of the CSI-RS signal to achieve demodulation and decoding of two different signals.

(2) The resources allocated to the power-saving signal conflict with the resources allocated to the SRS.

Specifically, if the UE is not configured with an uplink channel (such as PUSCH or PUCCH), then when the SRS sent by the UE conflicts with the power saving signal in the time domain, the UE may use any of the following methods or combinations to receive the power saving signal.

i. The priority of the SRS signal is higher than that of the power saving signal.

In this way, it can be ensured that the UE only supports uplink signal transmission or downlink signal reception at the same time.

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

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

In this way, the UE can be ensured to achieve optimal power saving effect.

Specifically, if the UE has been configured with an uplink channel (such as PUSCH or PUCCH) and configured with periodic SRS, semi-persistent SRS or aperiodic SRS, then the UE can further use any one or combination of the following methods to generate power saving signals. take over.

i. The priority of the SRS signal is higher than that of the power saving signal.

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

ii. SRS and power-saving signals can be sent and received at the same time, if the terminal is a full-duplex terminal.

iii. The priority of the power-saving signal may be higher than that of the SRS signal. Especially if periodic SRS or semi-persistent SRS is configured, the terminal may transmit SRS at the next SRS transmission opportunity.

(3) The resources allocated by the power-saving signal conflict with the resources allocated by DMRS.

DMRS is mainly used for downlink physical channel estimation, such as PDCCH, PDSCH or PBCH, etc. 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 can be multiplexed with the resources allocated to the PDSCH or PUSCH. Then the power saving signal may conflict with the DMRS received using other candidate PDCCHs, or with the DMRS received using the PDSCH. There may also be resource conflicts. Resource collision occurs with DMRS received using PBCH.

For resource conflicts with DMRS received using other candidate PDCCHs, please refer to the above application scenario 2, which will not be described again here.

For resource conflicts with DMRS received using PDSCH, please refer to the above application scenario four, which will not be described again here.

For resource conflicts with DMRS used for PBCH reception, please refer to the above application scenario 1, which will not be described again here.

Application scenario six: The UE prioritizes different radio network temporary identities (RNTI) to detect power saving signals.

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

For example: Power Saving RNTI, PS-RNTI) vs. Cell Radio Network Temporary Identity (Cell RNTI, C-RNTI).

Another example: PS-RNTI vs. System Information Wireless Network Temporary Identifier (System Information, RNTI, SI-RNTI).

Another example: PS-RNTI vs. Random Access Wireless Network Temporary Identity (Random Access RNTI, RA-RNTI).

Another example: PS-RNTI vs. Paging Radio Network Temporary Identity (Paging RNTI, P-RNTI).

The UE can generate corresponding priority information for various RNTIs configured by the base station to ensure the reception performance of certain candidate PDCCHs.

For example, the priority information can be set as: SI-RNTI > RA-RNTI > P-RNTI > PS-RNTI > C-RNTI.

The above is only an example of priority information and is not the only priority information.

Application scenario seven: When the resources allocated to the UE's power saving signal conflict with the resources allocated to the PDCCH of other UEs in the same cell, the base station's method of sending the power saving signal.

Since the DRX parameter configurations of different UEs can be different in the same cell, this will lead to different starting points of the DRX activation period of different UEs. Therefore, when one UE is in the DRX non-activated state, another UE will be in the DRX non-activated state. A UE is in DRX enabled state. Obviously, the power saving signal of the UE in the DRX non-activated state will conflict with the PDCCH of the UE in the DRX activated state. This will increase the interference to the power saving signal.

Since the PDCCH monitoring period of the UE in the DRX enabled state is usually relatively dense (for example, 1 time slot), and the power saving signal monitoring period of the UE in the DRX non-activated state is relatively long (such as one DRX cycle), then, in order to achieve For better power-saving signal reception performance, the base station can configure a certain listening priority to allow UEs in the DRX-enabled state to avoid the PDCCH listening cycles of other UEs to ensure that user UEs in the DRX-non-activated state receive power-saving signals. correct detection.

Application scenario eight: When the UE determines that a resource conflict occurs between the power saving signal and other signals (such as other channels or reference signals), and if the UE determines that the above first criterion indicates not to detect the power saving signal, then when the UE determines the reception strategy of the power saving signal, It needs to be judged whether to perform regular DRX operations, or whether to perform regular channel or signal reception, or whether to continue sleeping. Specifically, the following situations may exist but are not limited to the following.

(1) If the UE determines the signal transmission resource configuration information, it indicates that each power-saving signal listening period contains 1 listening opportunity (for example, the duration in the search space of the power-saving signal is set to 1, and one listening opportunity includes 1 time slot. ), the UE can perform but is not limited to any one of the following operations or combinations.

i. The UE performs subsequent power saving operations according to the method configured on the base station side.

For example, if the configuration method on the base station side is: if the UE does not successfully detect the power saving signal, it goes to sleep; then when the UE determines that the power saving signal is not detected, it enters the sleep state.

For another example, if the base station side configuration method is: if the UE does not successfully detect the power saving signal, it will perform a conventional DRX operation, or perform a conventional channel or signal reception; then when the UE determines not to detect the power saving signal, it will perform a conventional DRX operation. DRX operation, or, perform regular channel or signal reception.

ii. The UE enters the sleep state.

iii. The UE performs conventional DRX operations, or performs conventional channel or signal reception.

iiii. The UE maintains the current state unchanged.

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

For example, if the UE is currently performing a regular DRX operation, or is performing regular channel or signal reception, the UE continues to perform the regular DRX operation, or continues to perform regular channel or signal reception.

(2) If the UE determines the signal transmission resource configuration information, indicating that each power-saving signal listening period contains multiple listening opportunities (for example, the duration in the search space of the power-saving signal is set to 2, where one listening opportunity includes 1 time slot, that is, there are 2 listening opportunities), the UE can perform but is not limited to any one of the following operations or combinations. Optionally, the base station may send a power saving signal at each listening opportunity.

i. If the UE determines that within a power-saving signal listening period, the resource conflict does not occur at the first listening opportunity, then within the power-saving signal listening period, the power-saving signal will be issued at the subsequent listening opportunity after the resource conflict occurs. detection, or, does not detect the power saving signal.

ii. If the UE determines that a resource conflict occurs at the first listening opportunity within a power-saving signal listening period, then within the power-saving signal listening period, the power-saving signal will be processed at the subsequent listening opportunity after the resource conflict occurs. Detect, or do not detect the power saving signal.

For the situation where the UE has multiple listening opportunities within a power-saving signal listening period, if the UE has detected a power-saving signal at one listening opportunity, the power-saving signal can be detected at other listening opportunities within the power-saving signal listening period. It is also possible not to detect the power saving signal.

When the UE receives the power saving signal, it will decide whether to perform subsequent regular DRX operations, or whether to perform regular channel or signal reception, or to continue to remain in the sleep state according to the instructions of the power saving signal.

If the UE does not detect the power saving signal during each power saving signal listening period, the UE will continue to detect the power saving signal at subsequent monitoring opportunities, or perform corresponding operations based on the method configured by the base station, or directly enter sleep. status, or perform regular DRX operations, or perform regular channel or signal reception, or maintain the current status unchanged.

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

Application scenario nine: When the base station determines that a resource conflict occurs between the power saving signal and other signals (such as other channels or reference signals), and if the base station determines that the above second criterion indicates not to send the power saving signal, the base station determines whether to send the power saving signal. The strategy, specifically, can exist in but is not limited to the following situations.

(1) If the base station determines the signal transmission resource configuration information, indicating that each power-saving signal listening period of the UE includes one listening opportunity (for example, the duration in the search space of the power-saving signal is set to 1, and one listening opportunity includes 1 time slot), the base station does not send a power saving signal.

(2) If the base station determines that the signal transmission resource configuration information indicates that each power-saving signal listening cycle of the UE contains multiple listening opportunities (for example, the duration in the search space of the power-saving signal is set to 2, in which one listening time The opportunity includes 1 time slot, that is, there are 2 monitoring opportunities), then the base station can perform any of the following operations.

i. If the base station determines that within a power-saving signal listening cycle, the resource conflict between the power-saving signal and other signals does not occur at the first listening opportunity, then the base station sends the power-saving signal at the first listening opportunity, and During the power-saving signal listening period, a power-saving signal is sent at a subsequent listening time after a resource conflict occurs, or a power-saving signal is not sent.

ii. If the base station determines that within a power-saving signal listening cycle, the resource conflict between the power-saving signal and other signals occurs at the first listening opportunity, then the base station shall, within the power-saving signal monitoring cycle, detect the resource conflict at the listening opportunity. At subsequent monitoring opportunities, a power saving signal is sent.

Various parameters configured by the base station in the above embodiment are only examples.
