The 3GPP (Third Generation Partnership project) standard protocol introduces a DRX (Discontinuous Reception) power saving strategy in an LTE (Long Term Evolution) system. The network side device may notify the terminal of transmitting or receiving in the DRX cycle through the energy saving control information, or notify the terminal of skipping the DRX cycle through the energy saving control information, that is, not transmitting or receiving in the DRX on duration.

Furthermore, the use of "and/or" in the specification and claims means that at least one of the connected objects, such as a and/or B, means that three cases, a alone, B alone, and both a and B, exist.

Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

Embodiments of the present invention are described below with reference to the accompanying drawings. The embodiment provided by the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, or an Evolved Long Term Evolution (lte) system, or a subsequent Evolved communication system.

Fig. 1 is a structural diagram of a network system according to an embodiment of the present invention, as shown in fig. 1, including a terminal 11 and a network-side device 12, where the terminal 11 may be a mobile communication device, for example: the terminal may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), or a Wearable Device (Wearable Device), and the specific type of the terminal 11 is not limited in the embodiments of the present invention. The network side device 12 may be a 5G network side device (e.g., a gNB, a 5G NR NB), or may be a 4G network side device (e.g., an eNB), or may be a 3G network side device (e.g., an NB), or a network side device in a subsequent evolved communication system, and so on, it should be noted that a specific type of the network side device 12 is not limited in the embodiment of the present invention.

The 3GPP standard protocol introduces a DRX energy-saving strategy in the LTE system, and the terminal 11 may periodically listen to a paging Channel in an RRC (Radio Resource Control) idle state, or may close a receiver circuit in a RRC connected state for most of the time when no data burst frame (data burst) is transmitted, and only keep periodically listening to a PDCCH (Physical Downlink Control Channel). As shown in fig. 2, in each DRX cycle (DRX cycle), the terminal 11 is before DRX, and the network side device 12 may transmit control information to the terminal 11 through a control channel, and the terminal 11 may detect the control information at a corresponding time. If the terminal 11 detects the control information, or if the terminal 11 detects the control information and instructs the terminal to monitor the PDCCH at the DRX on duration in the DRX cycle, the terminal 11 may start the DRX on duration timer, or monitor the PDCCH at the DRX on duration in the DRX cycle. Otherwise, the terminal 11 does not start the DRX OnDuration timer, or does not monitor the PDCCH in the DRX OnDuration in the DRX cycle, and the control information for transmitting the above information may be regarded as a wake-up signal, which is one of the energy saving control information. Further, if the terminal 11 detects the PDCCH for scheduling data in the DRX operation, the terminal 11 starts a DRX inactivity timer (inactivity timer) and continues monitoring the control channel in the inactivity period. The time periods corresponding to the DRX OndurationTimer and the DRX inactiveTimer are both DRX active time (active period).

The network side device 12 may notify the terminal 11 of transmitting or receiving in the DRX OnDuration in the DRX cycle through the energy saving control information, or notify the terminal 11 of skipping the DRX cycle through the energy saving control information, that is, not transmitting or receiving in the DRX OnDuration. The terminal 11 needs to monitor the energy saving control channel, and the monitoring action on the monitoring resource of the energy saving control channel may conflict with the transmission or reception action (e.g. the transmission or reception action of other physical signals) indicated by other network side devices, that is, the monitoring action and other transmission or reception actions occur simultaneously or within a relatively close time, for example, the monitoring action and other transmission or reception actions occur on the same OFDM symbol or occur on an adjacent OFDM symbol, which results in the monitoring resource of the energy saving control channel conflicting with the resource corresponding to other actions.

The energy-saving control channel is a control channel for transmitting energy-saving control information, or the energy-saving control channel is a control channel scrambled by using a PS-RNTI (power save-RNTI).

The control channel may transmit control information instructing the terminal to perform other actions in addition to transmitting the wake-up signal, for example:

the terminal equipment performs BWP (bandwidth Part) switching;

the terminal equipment activates or deactivates an object, wherein the object is a cell group or a carrier group;

a change in the number of (maximum) layers transmitted;

the terminal equipment triggers the report of the channel state information;

the terminal equipment triggers the sending of the detection reference signal;

receiving a tracking reference signal by the terminal equipment;

the terminal equipment receives the channel state information reference signal;

whether the terminal device performs at least one of measurement of beam management, measurement of radio link monitoring, and radio resource management measurement during the DRX active period.

For the situation of the resource conflict, the embodiments of the present invention are configured to provide a channel monitoring control method and a terminal, so as to solve the monitoring behavior of the terminal when the monitoring of the energy saving control channel conflicts with other behaviors, and further solve whether the terminal performs the terminal behavior of PDCCH monitoring in DRX on duration when the terminal cannot monitor the energy saving control channel due to the conflict. The following specifically describes examples of the present invention.

Fig. 3 is a flowchart of a channel monitoring control method according to an embodiment of the present invention. As shown in fig. 3, the channel monitoring control method is applied to a terminal, and the method includes the following steps:

step 301: executing a first operation under the condition that the monitoring resource of the energy-saving control channel conflicts with the resource corresponding to the first behavior; wherein the first operation comprises one of: monitoring the energy-saving control channel; not monitoring the energy-saving control channel; the energy saving control channel is not monitored on a core set (control resource set) using a currently activated TCI (Transmission Configuration Indicator) state (state).

The energy-saving control channel may be referred to as an energy-saving PDCCH, or may be referred to as a PS-PDCCH for short, and the WUS information may be indication information transmitted in the energy-saving PDCCH. The listening resource of the energy saving control channel may be understood as a listening occasion (monitoring occasion) of the energy saving control channel, and each listening occasion may include at least one OFDM symbol. The first behavior may refer to other behaviors than the listening behavior of the energy saving control channel, and may be, for example, a transmitting or receiving behavior of other physical signals. The above monitored resource of the energy-saving control channel conflicts with the resource corresponding to the first behavior, and it can be understood that, at the monitoring time of the energy-saving control channel, the terminal needs to receive or transmit the signal corresponding to the first behavior, for example, monitoring of the control channel, SRS transmission, or CSI reporting. The monitored resource of the energy-saving control channel conflicts with the resource corresponding to the first behavior, and it can also be understood that the monitored resource of the energy-saving control channel overlaps with the resource corresponding to the first behavior.

In the embodiment of the invention, the terminal can determine the monitoring behavior of the energy-saving control channel according to the priority of signal processing under the condition that the monitoring resource of the energy-saving control channel conflicts with the resource corresponding to other behaviors. For example, when the priority of the energy saving control channel monitoring is higher, the first operation may be to monitor the energy saving control channel; when the priority of monitoring the energy-saving control channel is lower, the first operation may be not to monitor the energy-saving control channel; when the priority of the energy saving control channel monitoring is lower, the first operation may be not to monitor the energy saving control channel on the CORESET using the currently activated TCI state.

Through the scheme, the embodiment of the invention confirms the monitoring behavior of the terminal on the energy-saving control channel under the condition that the monitoring resource of the energy-saving control channel conflicts with the resources corresponding to other behaviors, and is favorable for improving the communication performance of the terminal.

Optionally, the first behavior includes at least one of:

SSB (Synchronization Signal and PBCH block, Synchronization Signal/physical broadcast Channel Signal block or Synchronization Signal block) measurement or CSI-RS (Channel State Information Reference Signal) measurement;

DCI (Downlink Control Information) indicates that a part of time domain resources in the monitored resources of the energy-saving Control channel are uplink time domain resources or flexible time domain resources;

the DCI indicates that a part of time domain resources in the monitored resources of the energy-saving Control Channel is used for transmission of a PUCCH (Physical Uplink Control Channel), a PUSCH (Physical Uplink Shared Channel), a PRACH (Physical Random Access Channel), or an SRS (Sounding Reference Signal);

after the terminal initiates Random Access, monitoring a PDCCH scrambled by RA-RNTI (Random Access-Radio Network temporary Identity) in a part of time domain resources in monitoring resources of the energy-saving control channel, and ignoring an activated TCI state of CORESET associated with RAR (Random Access Response) search space (search space);

the serving cell of the terminal changes;

the DRX state of the terminal is changed;

the BWP of the terminal changes;

and on the time domain resource monitored by the energy-saving control channel, the terminal monitors S CORESET, wherein S is more than 1.

The partial time domain resource in the monitored resource of the energy saving control channel may refer to at least one OFDM (Orthogonal Frequency Division Multiplexing) symbol (symbol) in the monitored occasion of the energy saving control channel.

The DCI indicates that a part of time domain resources in the monitored resources of the energy-saving control channel are uplink time domain resources or flexible time domain resources, and may include the following embodiments: the DCI indicates that a part of OFDM symbols in a listening opportunity of the power saving control channel are flexible symbols (flexible symbols) or uplink symbols (uplink symbols).

The DCI indicates that a part of time domain resources in the monitored resources of the energy-saving control channel are used for transmission of a PUCCH, a PUSCH, a PRACH, or an SRS, and may include the following embodiments: the DCI indicates that a portion of OFDM symbols in a listening occasion of the energy-saving control channel are used for transmission of a PUCCH, PUSCH, PRACH, or SRS.

In the embodiment of the present invention, when the monitored resources of the energy saving control channel conflict with the resources corresponding to the various first behaviors, the terminal may monitor the energy saving control channel, or may not monitor the energy saving control channel on the CORESET using the currently activated TCI state.

In this embodiment of the present invention, in a case that the first action includes an SSB measurement or a CSI-RS measurement, the SSB measurement or the CSI-RS measurement may include at least one of RRM (Radio Resource Management) measurement, RLM (Radio Link Monitoring) measurement, BFR (Beam Failure Recovery) measurement, LI-RSRP (Layer1 Reference Signal Received Power) measurement.

Wherein the RRM measurement may include at least one of an intra-frequency (intra-frequency) measurement, an inter-frequency (inter-frequency) measurement, and an inter-network (inter-RAT) measurement. An RLM measurement may be understood as a measurement that evaluates whether the quality of the link signal is above a certain threshold (e.g. Qin) or below a certain threshold (e.g. Qout). The BFR measurement may include at least one of a measurement in which the terminal evaluates whether the quality of the Signal is below a certain threshold (e.g., Qout) and a measurement of candidate beamlist RS based on a BFD-RS (Beam Failure Detection-Reference Signal).

Optionally, when the first action includes SSB measurement or CSI-RS measurement, if the monitored resource of the energy-saving control channel overlaps with the measurement resource corresponding to the SSB measurement or the CSI-RS measurement on any time domain resource, it is determined that the monitored resource of the energy-saving control channel conflicts with the measurement resource corresponding to the SSB measurement or the CSI-RS measurement.

For example, if a terminal listens to a WUS with a listening opportunity and a measurement resource (SSB or CSI-RS) overlapping on any OFDM symbol, it may be determined that the listening resource of the energy saving control channel conflicts with a measurement resource corresponding to the SSB measurement or the CSI-RS measurement.

Optionally, when the first action includes SSB measurement or CSI-RS measurement, if a time interval between the monitored resource of the energy-saving control channel and the measurement resource corresponding to the SSB measurement or the CSI-RS measurement is smaller than or equal to a preset value, it is determined that the monitored resource of the energy-saving control channel conflicts with the measurement resource corresponding to the SSB measurement or the CSI-RS measurement.

For example, if a terminal listens to x (e.g., x ═ 1) OFDM symbols before a measurement resource (SSB or CSI-RS) for a WUS, or x OFDM symbols after a measurement resource (SSB or CSI-RS), it may be determined that the listening resource of the energy-saving control channel collides with a measurement resource corresponding to the SSB measurement or the CSI-RS measurement.

Optionally, if the terminal does not monitor the energy-saving control channel on the CORESET using the currently activated TCI state, the method further includes:

and monitoring a control channel on the CORESET associated with the RAR search space by using the activated TCI state of the CORESET associated with the RAR search space.

The control channel is a control channel scrambled by RA-RNTI (Cell Radio Network Temporary Identifier), C-RNTI (Cell Radio Network Temporary Identifier) and MCS-C-RNTI (Modulation and coding scheme Cell Radio Network Temporary Identifier).

The monitoring of the control channel by the terminal means that the terminal performs decoding of the control channel on at least one target PDCCH candidate resource in a search space set (search space sets) associated with the core set.

In this embodiment, although the terminal does not use the currently activated TCI status to listen to the energy-saving control channel on the CORESET, the terminal may still listen to the control channel, and here, the terminal may use the activated TCI status of the CORESET associated with the RAR search space to listen to the control channel on the CORESET associated with the RAR search space.

In the embodiment of the invention, if the priority of monitoring the energy-saving control channel is lower, the terminal can monitor the energy-saving control channel on the CORESET without using the currently activated TCI state, and monitor the control channel on the CORESET associated with the RAR search space by using the activated TCI state of the CORESET associated with the RAR search space, so that the priority of signal processing is fully considered, and the monitoring of the control channel is realized as much as possible.

In the embodiment of the present invention, the behaviors of the terminal, such as the change of the serving cell of the terminal, the change of the DRX state of the terminal, and the change of the BWP of the terminal, are all behaviors of the change of the terminal state, and the terminal may abandon the monitoring of the energy saving control channel or the terminal may not monitor the energy saving control channel when resources corresponding to the behaviors conflict with monitored resources of the energy saving control channel.

In a case where the terminal is configured with CA (Carrier Aggregation) or DC (Dual Connectivity), the terminal may cause an interrupt (interruption) due to some factors, or the terminal may cause the above-mentioned change in the terminal state due to some factors. The following discussion is divided into different cases.

First, in the case of EN-DC (E-UTRA is MCG, NR is double connectivity of SCG, E-UTRA NR dual connectivity with MCG using E-UTRA and SCG using NR), the following factors may cause the terminal to be interrupted on PScell (Primary Secondary Cell, Primary serving Cell of Secondary Cell group) or Scell (Secondary Cell):

during DRX, an E-UTRA (Evolved Universal Radio Access, Evolved UMTS Terrestrial Radio Access) Pcell (Primary cell) changes between activation and deactivation of DRX; alternatively, the first and second electrodes may be,

E-UTRA Pcell changes from non-DRX to DRX; alternatively, the first and second electrodes may be,

E-UTRA Scell in MCG (Master Cell Group) or E-UTRA Scell in SCG (Secondary Cell Group) is added or released; alternatively, the first and second electrodes may be,

E-UTRA Scell in MCG or E-UTRA Scell in SCG is activated or deactivated; alternatively, the first and second electrodes may be,

measuring on a SCC (Secondary Component Carrier) deactivating a Scell in an E-UTRA MCG or an NR (New Radio, New air interface) SCG; alternatively, the first and second electrodes may be,

UL/DL (uplink/downlink, uplink or downlink) BWP is switched on PScell or Scell in SCG; alternatively, the first and second electrodes may be,

one secondary UL carrier or one UL carrier is configured or de-configured.

Secondly, in case of stand-alone networking (SA) NR CA, the following factors may cause the termination on Pcell or activated Scell:

the Scell is configured, de-configured, activated or deactivated s; alternatively, the first and second electrodes may be,

one secondary UL carrier or one UL carrier is configured or de-configured; alternatively, the first and second electrodes may be,

measured on SCC deactivating Scell in NR SCG;

UL/DL BWP is switched on PScell or Scell in SCG.

Thirdly, in case of NE-DC (NR-E-UTRA Dual Connectivity ), the following factors may cause the termination to be interrupted on Pcell or Scell:

during DRX, E-UTRA PScell transitions between DRX active and inactive; alternatively, the first and second electrodes may be,

E-UTRA PScell changes from non-DRX to DRX; alternatively, the first and second electrodes may be,

E-UTRA PScell or Scell in SCG, or E-UTRA SCell in MCG are added or released; alternatively, the first and second electrodes may be,

E-UTRA PScell or Scell in SCG, or E-UTRA SCell in MCG is activated or deactivated; alternatively, the first and second electrodes may be,

measured on SCC deactivating Scell in E-UTRA SCG or NR MCG; alternatively, the first and second electrodes may be,

PUSCH/PUCCH carrier configuration and de-configuration in NR MCG; alternatively, the first and second electrodes may be,

UL/DL BWP is switched on Pcell or Scell in MCG.

Fourthly, in the case of NR-DC, the following factors may cause the termination to be discontinued on Pcell, Pscell or Scell:

SCells are configured, de-configured, activated or deactivated; alternatively, the first and second electrodes may be,

measured on SCC deactivating Scell in NR SCG; alternatively, the first and second electrodes may be,

UL/DL BWP is switched on Pcell, PScell or Scell; alternatively, the first and second electrodes may be,

during DRX, transition between active and inactive, or change from non-DRX to DRX.

When the above actions occur, the terminal cannot perform downlink receiving operation, and when the terminal collides with a monitoring occasion of the PS-PDCCH, the terminal may not monitor the PS-PDCCH.

In the embodiment of the present invention, on the time domain resource monitored by the energy saving control channel, the terminal may need to monitor on multiple (i.e., S) CORESETs, and a resource corresponding to the behavior monitored by the terminal on the multiple CORESETs conflicts with the monitored resource of the energy saving control channel, so that the terminal may monitor the energy saving control channel preferentially, or may abandon the energy saving control channel for monitoring.

Further, if the priority of the behavior that the terminal monitors on a plurality of CORESET is low, the terminal may abandon the energy-saving control channel for monitoring; if the priority of the behavior that the terminal monitors on a plurality of CORESETs is higher, the terminal can monitor the energy-saving control channel preferentially.

Further, when the QCL-type attributes on the overlapped PDCCH monitoring resources are different, the terminal may abandon monitoring of part of the PDCCH.

When a terminal performs PDCCH monitoring with different QCL-type attributes on PDCCH monitoring opportunities that overlap in time, if the terminal is configured with only one serving cell or operates in a carrier aggregation manner in the same frequency band, and monitors a plurality of PDCCH candidates on a plurality of CORESETs on the monitoring opportunities that overlap in time, and the plurality of CORESETs on active BWPs of the plurality of cells have the same or different QCL-type attributes, the terminal only monitors one CORESET, and performs PDCCH monitoring on one or more CORESETs having the same QCL-type attributes as the CORESET, which are located on the active BWP of the one or more serving cells.

Further, when the common search space is configured on the CORESET, the CORESET is the CORESET with the lowest CORESET number corresponding to the lowest common search space number; otherwise, selecting the CORESET with the lowest CORESET number in the terminal search space set. The lowest search space set number is determined in the UE search space set of at least one PDCCH candidate UE in all UE search space sets in the time-overlapping PDCCH monitoring occasions. When determining to listen to the CORESET, the SSB considers the QCL attribute to be different from that of the CSI-RS.

In the above situation, since the terminal cannot monitor the PS-PDCCH, or the terminal cannot monitor the energy-saving control channel, the embodiment of the present invention further determines a further terminal behavior when the terminal cannot monitor the PS-PDCCH, which is specifically as follows.

Optionally, if the terminal does not monitor the energy-saving control channel, the method further includes:

performing a default action in a DRX duration associated with a monitored resource of the energy saving control channel; alternatively, the first and second electrodes may be,

performing the default behavior in a DRX operation associated with the monitored resource of the energy-saving control channel;

wherein the default behavior comprises at least one of:

starting a DRX duration timer (timer);

monitoring the PDCCH according to the configuration of the network side equipment;

carrying out periodic or semi-continuous SRS transmission according to the configuration of the network side equipment;

reporting periodic or semi-continuous Channel State Information (CSI) according to the configuration of the network side equipment;

making the SSB measurements or the CSI-RS measurements.

This embodiment clarifies the further behavior of the terminal in case the terminal does not listen to the energy saving control channel. As shown in fig. 4, in an aspect, the terminal may perform a default behavior in the DRX on associated with power saving control channel monitoring, for example, the terminal may perform transceiving by default in the DRX on, the terminal may start a DRX on timer, the terminal may perform SSB measurement or CSI-RS measurement by default in the DRX on, and so on. Therefore, the service delay of the terminal can be reduced, and the reliability of the link is ensured. On the other hand, the terminal may not perform a default behavior in the DRX on associated with the power saving control channel monitoring, for example, the terminal may not transmit or receive in the DRX on, the terminal may not start the DRX on timer, the terminal may not perform an SSB measurement or a CSI-RS measurement in the DRX on, and so on. Thus, power consumption of the terminal can be reduced.

Optionally, if the network side device configures monitoring resources of N energy-saving control channels, and the terminal abandons monitoring of the energy-saving control channels at M monitoring resources, the terminal executes the default behavior during a discontinuous reception duration associated with the monitoring resources of the energy-saving control channels, where N is greater than or equal to 1, and M is less than or equal to N. As shown in fig. 5, before DRX operation, the network side device configures 6 monitoring occasions of the power saving control channel, where the 6 monitoring occasions are a1, a2, b1, b2, c1, and c 2.

Wherein, M may be 1, N, or greater than a certain threshold, or greater than a certain proportion.

Therefore, the service delay of the terminal can be reduced, and the reliability of the link is ensured.

Further, before the DRX on duration, the network side device configures monitoring occasions of a plurality of energy saving control channels, and if monitoring of one energy saving control channel is cancelled from monitoring of all energy saving control channels at one of the monitoring occasions, the terminal performs the default behavior in the DRX on duration associated with the monitoring of the energy saving control channels. If the monitoring of all the energy saving control channels on one of the monitoring occasions is cancelled, the terminal also executes the default action in the DRX on duration associated with the monitoring of the energy saving control channels.

Further, if the terminal cannot monitor on a part of the monitored resources due to resource conflict, but still detects the energy-saving control channel on the remaining monitored resources, the terminal may perform a transceiving operation according to an indication of the energy-saving control channel. If the terminal cannot monitor on part of the monitored resources due to resource conflict and the terminal does not detect the energy-saving control channel on the rest monitored resources, the terminal can execute the default behavior.

Optionally, if the network side device configures that the terminal monitors the energy-saving control channels on X CORESET, and the terminal abandons all monitoring resources corresponding to Y CORESET to monitor the energy-saving control channels, the terminal executes the default behavior during the discontinuous reception duration associated with the monitoring resources of the energy-saving control channels, where X is greater than or equal to 1, and Y is less than or equal to X. As shown in fig. 5, before DRX operation, the network side device configures 3 monitoring occasions corresponding to CORESET (or search space), where the 3 CORESET are A, B, C respectively, and each CORESET includes two monitoring occasions.

Further, before DRX operation, the network side device configures the terminal to monitor the energy saving control channels on a plurality of core sets/search spaces, and if the monitoring time corresponding to a certain core sets/search space abandons monitoring, the terminal executes the default behavior.

Optionally, if the network side device configures that the terminal uses L TCI states to monitor the energy saving control channel, and the terminal abandons all monitoring resources corresponding to P TCI states to monitor the energy saving control channel, the terminal executes the default behavior in the discontinuous reception duration associated with the monitoring resources of the energy saving control channel, where L is greater than or equal to 1, and P is less than or equal to L. As shown in fig. 5, before DRX operation, the network side device configures monitoring occasions corresponding to 3 TCI states, where the 3 TCI states are A, B, C respectively, and each TCI state includes two monitoring occasions.

Further, before DRX operation, the network side device configures the terminal to monitor the energy saving control channel using multiple TCI states, and if a certain TCI state or monitoring time corresponding to QCL (Quasi Co-Location ) assumption (allocation) abandons monitoring, the terminal executes the above default behavior.

Optionally, the method further includes:

receiving RRC information sent by network side equipment;

if the RRC information indicates that the terminal executes the default behavior, the terminal executes the default behavior in a discontinuous reception duration associated with the monitored resource of the energy-saving control channel;

if the RRC message indicates that the terminal does not perform the default behavior, the terminal does not perform the default behavior in a discontinuous reception duration associated with the monitored resource of the energy-saving control channel.
