Description

Method and device for detecting downlink control channel and terminal equipment

Technical Field

The embodiment of the application relates to the technical field of mobile communication, in particular to a method and a device for detecting a downlink control channel and terminal equipment.

Background

In a New Radio (NR) system, a network may configure multiple Control Resource sets (CORESET) on each downlink bandwidth Part (BWP), where the CORESET defines a time-frequency domain Resource, and specifically, specifies a frequency domain size of the CORESET in a frequency domain and a number of consecutive symbols occupied by the CORESET in a time domain. Meanwhile, the next generation base station (gNB) may associate 1 or more Search spaces (Search spaces) with each CORESET to determine a time period for a User Equipment (UE) to detect the control channel. Wherein each Search Space needs to be associated to a core set.

On the other hand, in the NR system, each MAC entry has a Discontinuous Reception (DRX) configuration, and it should be noted that the configuration parameters of DRX (abbreviated DRX parameters) are applicable to all configured core sets and Search spaces. In a DRX cycle (DRX cycle), if the UE is in an awake state, the UE needs to blindly detect possible positions of all Physical Downlink Control Channels (PDCCHs); if a PDCCH is monitored in any possible PDCCH position, and if the PDCCH schedules an uplink or downlink newly transmitted data, the timer-drx-inactivity timer is restarted, so as to extend the time length in the awake state.

In the current configuration, Search Space and CORESET are configured through RRC signaling, and for the Search Space with a small configuration period, UE needs frequent blind detection of PDCCH, which results in increased energy consumption of the terminal; for Search Space with a long configuration period, the UE does not need to frequently blind-detect the PDCCH, but may sacrifice scheduling flexibility.

Fig. 2 is a schematic flowchart of a method for detecting a downlink control channel according to an embodiment of the present application, where as shown in fig. 2, the method for detecting a downlink control channel includes the following steps:

step 201: the terminal device acquires the first information.

In the embodiment of the application, the terminal device may be any device capable of communicating with a network device, such as a mobile phone, a tablet computer, a notebook, a desktop, a vehicle-mounted terminal, and a wearable device.

In an embodiment of the present application, each MAC entity of the terminal device has a DRX configuration, which includes a set of DRX parameters, and in an embodiment, the set of DRX parameters includes at least one of:

a first time parameter for determining a start time of the DRX cycle;

a second time parameter, configured to determine a first duration corresponding to that the terminal device is in an awake state in the DRX cycle;

a third time parameter, configured to determine a second duration for which the terminal device continuously maintains the awake state after successfully decoding a downlink control channel and scheduling a newly transmitted data by the downlink control channel;

a fourth time parameter, configured to determine a short cycle duration corresponding to the DRX cycle;

and the fifth time parameter is used for determining the long cycle duration corresponding to the DRX cycle.

Without limitation, the set of DRX parameters may also include further parameters, such as: drx-SlotOffset, drx-RecransmissionTimerL, drx-RecransmissionTimeUL, drx-ShortCycleTimer, drx-HARQ-RTT-TimerL, and drx-HARQ-RTT-TimeUL.

Further, for the first time parameter in the above scheme, the starting time corresponding to the terminal device being in the awake state in the DRX cycle is the first time determined based on the first time parameter in the set of DRX parameters. Here, the start time (i.e., the first time) of the awake state may be any time, and in one example, the start time (i.e., the first time) corresponding to the terminal device being in the awake state in the DRX cycle corresponds to an integer multiple of the period of the search space. For example: the period of the Search Space is configured to be 1 slot, and assuming that the starting time corresponding to the terminal device being in the awake state in the DRX period may be 4 times the period of the Search Space, the terminal device needs to start detecting the PDCCH in time slots 0,4,8, ….

Further, the second time parameter and/or the third time parameter and/or the fourth time parameter and/or the fifth time parameter in the above scheme are represented by an absolute time length (e.g., n milliseconds) or a number of consecutive time units (e.g., m PDCCH subframes). Here, the time unit is a subframe, or a slot, or a symbol, or a Short Transmission Time Interval (STTI).

In a specific implementation, the first time parameter may be represented by drx-StartOffset, the function corresponding to the second time parameter may be implemented by a timer drx-onDurationTimer, the function corresponding to the third time parameter may be implemented by a timer drx-inactivtytimer, the correspondence between the four time parameters may be represented by drx-ShortCycle, and the fifth time parameter may be represented by drx-LongCycle.

In an embodiment of the present application, a correspondence relationship between the first information and the at least one control resource set and/or the at least one search space is configured by a network device.

Further, the first information corresponds to one control resource set and a part of or the whole search space associated with the one control resource set; or, the first information corresponds to a plurality of control resource sets and a partial search space or a whole search space respectively associated with the plurality of control resource sets.

For example: assuming that SearchSpace associated with CORESET1 is SS1 and SS2, SearchSpace associated with CORESET2 is SS3, and SearchSpace associated with CORESET3 is SS4, SS5 and SS6, in an example, first information configured for the terminal device by the network side corresponds to CORESET1 and SS 1. In another example, the first information configured for the terminal device by the network side corresponds to CORESET3 and SS4, SS5, and SS 6. In yet another example, the first information configured by the network side to the terminal device corresponds to CORESET1 and SS1, and CORESET2 and SS 3.

In an embodiment of the present application, when the at least one control resource set includes a plurality of control resource sets: different ones of the plurality of control resource sets are configured on a same bandwidth part BWP; alternatively, different ones of the plurality of control resource sets are configured on different BWPs.

Step 202: and the terminal equipment detects a downlink control channel on at least one search space associated with at least one control resource set corresponding to the first information and the at least one control resource set according to the first information.

In this embodiment of the application, the first Information is a Radio Resource Control (RRC) signaling, a Downlink Control Information (DCI) signaling, a Media Access Control Element (MAC CE), or a first sequence (which may be an arbitrary sequence).

1) The first information is the situation of RRC signaling, and the first information comprises a group of Discontinuous Reception (DRX) parameters or a plurality of groups of DRX parameters; the terminal equipment detects a downlink control channel on at least one control resource set corresponding to the group of DRX parameters and at least one search space associated with the at least one control resource set according to the group of DRX parameters; or, the terminal device detects a downlink control channel on at least one search space associated with at least one control resource set and at least one control resource set corresponding to the multiple sets of DRX parameters, respectively, according to the multiple sets of DRX parameters.

Here, for the set of DRX parameters or each of the multiple sets of DRX parameters, the terminal device determines a first time period corresponding to the set of DRX parameters according to the set of DRX parameters or each of the multiple sets of DRX parameters, and detects a downlink control channel on at least one search space associated with at least one control resource set and at least one control resource set corresponding to the set of DRX parameters during the first time period, where the first time period is a time period in which the terminal device is in an awake state in a DRX cycle.

In an embodiment, in a case that the terminal is configured with the multiple sets of DRX parameters, the terminal determines at least one set of DRX parameters in an active state, and detects a downlink control channel on at least one search space associated with at least one control resource set and at least one control resource set corresponding to the at least one set of DRX parameters in the active state, respectively; and/or the terminal determines at least one group of DRX parameters in a deactivated state, and cancels the detection of the downlink control channel on at least one search space associated with at least one control resource set and at least one control resource set corresponding to the at least one group of DRX parameters in the deactivated state respectively. Here, the terminal device obtains second information, where the second information is used to determine at least one set of DRX parameters that needs to be activated and/or at least one set of DRX parameters that needs to be deactivated.

In the above scheme, each group of DRX parameters in the multiple groups of DRX parameters respectively corresponds to an index information; wherein, 1) the second information is DCI signaling or MAC CE, and the DCI signaling or the MAC CE is used to indicate index information corresponding to at least one group of DRX parameters that need to be activated respectively, and/or index information corresponding to at least one group of DRX parameters that need to be deactivated respectively. Or, 2) the second information includes at least one second sequence, and each of the at least one second sequence has a corresponding relationship with index information of a set of DRX parameters.

For example, the network side indicates 3 DRX indexes, namely index1, index2 and index3, to the terminal device through DCI signaling or MAC CE, where index1 corresponds to a set of DRX parameters S1, index2 corresponds to a set of DRX parameters S2, and index3 corresponds to a set of DRX parameters S3, and the terminal device determines three sets of DRX parameters that need to be activated based on the index 1.

For another example, the terminal device obtains a certain sequence, where the sequence has a corresponding relationship (e.g., an orthogonal relationship) with the DRX index of a set of DRX parameters, and the terminal device may determine, based on the sequence, the DRX index of the set of DRX parameters, so as to determine the set of DRX parameters that needs to be activated or deactivated.

In the above scheme of the embodiment of the application, the network side may configure a group of DRX parameters or multiple groups of DRX parameters for the terminal; if the first information only comprises a group of DRX parameters, the network side can change different DRX parameters through RRC reconfiguration information, so that the terminal can monitor different search spaces; if the first information includes multiple sets of DRX parameters, each set of DRX parameters may correspond to at least one of the control resource set and the search space. The terminal monitors the control channel in the corresponding search space only during the awake period determined by the corresponding set of DRX parameters. Further, the network side configures multiple sets of DRX parameters for the terminal, and under the condition that each set of DRX parameters corresponds to the search space, the network side may further activate or deactivate one or more sets of DRX parameters through the MAC CE or the DCI, and if a certain set of DRX parameters is deactivated, the terminal does not need to monitor the downlink control channel of the corresponding search space.

2) The first information is a DCI signaling or a MAC CE, where the first information includes first indication information, and the first indication information is used to indicate index information of a set of DRX parameters (that is, index information of a set of DRX parameters that needs to be activated); the terminal equipment determines at least one control resource set and a group of DRX parameters corresponding to at least one search space associated with the at least one control resource set according to the index information of the group of DRX parameters; and the terminal equipment determines a first time period in which the terminal equipment is in an awakening state in a DRX period according to the group of DRX parameters, and detects a downlink control channel in the at least one control resource set and at least one search space associated with the at least one control resource set in the first time period.

3) The first information is a condition of DCI signaling or MAC CE, and the first information includes second indication information, where the second indication information is used to indicate at least one control resource set and at least one search space associated with the at least one control resource set; the terminal device detects a downlink control channel on the at least one control resource set indicated by the second indication information and the at least one search space associated with the at least one control resource set.

4) The first information is a first sequence, and the first sequence has a corresponding relation with a group of DRX parameters; the terminal equipment determines at least one control resource set and a group of DRX parameters corresponding to at least one search space associated with the at least one control resource set according to the first sequence; and the terminal equipment determines a first time period in which the terminal equipment is in an awakening state in a DRX period according to the group of DRX parameters, and detects a downlink control channel in the at least one control resource set and at least one search space associated with the at least one control resource set in the first time period.

5) The first information is a first sequence, and the first sequence has a corresponding relation with at least one control resource set and at least one search space associated with the at least one control resource set; the terminal equipment determines at least one control resource set and at least one search space associated with the at least one control resource set according to the first sequence; the terminal equipment detects a downlink control channel on at least one control resource set and at least one search space associated with the at least one control resource set.

In the above scheme, a set of DRX parameters may be directly configured through RRC signaling, and then the downlink control channel on the corresponding search space is monitored based on the DRX parameters. The terminal may also configure an indication information through DCI signaling or MAC CE to indicate a set of DRX parameters that need to be activated, where the terminal acquires multiple sets of DRX parameters in advance (which may be acquired through RRC signaling), activates one set of DRX parameters after receiving the indication information, and then monitors a downlink control channel on a corresponding search space based on the DRX parameters. The terminal may also configure another indication information through DCI signaling or MAC CE to indicate a search space that needs to be monitored, where the terminal acquires a set of DRX parameters in advance, and after receiving the indication information, monitors a downlink control channel on the search space indicated by the indication information based on the DRX parameters.

Specifically, one DRX cycle includes two time periods, which are an On Duration (the terminal device is in an awake state) and an Opportunity for DRX (the terminal device is in a sleep state), respectively, where the time period On Duration is before the time period Opportunity for DRX, the terminal device starts to detect the PDCCH at a start time of the DRX cycle (determined based On a first time parameter), and continues to detect the PDCCH within the time period On Duration; 1) if the terminal device successfully decodes a downlink control channel and the downlink control channel schedules a newly transmitted data, a timer DRX-inactivity timer (corresponding to a third time parameter) is started, the terminal device will continuously maintain the awake state before the timer expires, and detect the PDCCH, and after the timer expires, the terminal device enters the sleep state until the starting time of the next DRX cycle arrives and re-enters the awake state. 2) If the terminal device does not successfully decode to a downlink control channel and the downlink control channel schedules a new transmission data, the terminal device enters a sleep state after the time period On Duration is over until the starting time of the next DRX period arrives and enters an awakening state again.

The technical solutions of the embodiments of the present application are illustrated by specific application examples below.

Application example 1

Referring to fig. 3, the network configures two core sets, i.e., core set1 and core set2, for one downlink BWP of one UE, where each core set has an associated Search Space, and the period of the Search Space associated with core set1 is different from the period of the Search Space associated with core set 2.

In this example, CORESET2 corresponds to the first information, i.e., the same set of DRX parameters. The set of DRX parameters may include a starting time of the DRX cycle at which the UE starts to detect the PDCCH, where the starting time is an integer multiple of a period corresponding to the Search Space, for example, the period of the Search Space is configured to be 1 slot, the starting time is 4 times the period, and the UE needs to start the DRX cycle at 0,4,8, …. In addition, the network device may indicate the start time of the DRX cycle to the UE through dynamic signaling (e.g., DCI).

The UE continuously detects the PDCCH in the time period On Duration; 1) if the terminal device successfully decodes a downlink control channel and the downlink control channel schedules a newly transmitted data, a timer DRX-inactivity timer (corresponding to a third time parameter) is started, the terminal device will continuously maintain the awake state before the timer expires, and detect the PDCCH, and after the timer expires, the terminal device enters the sleep state until the starting time of the next DRX cycle arrives and re-enters the awake state. 2) If the terminal device does not successfully decode to a downlink control channel and the downlink control channel schedules a new transmission data, the terminal device enters a sleep state after the time period On Duration is over until the starting time of the next DRX period arrives and enters an awakening state again.

Application example two

The network configures two CORESET for one UE, referring to fig. 4, CORESET1 and CORESET2, respectively, each CORESET is associated with a Search Space, and the period of the Search Space associated with CORESET1 is different from the period of the Search Space associated with CORESET 2. Here, it is not limited whether CORESET1 and CORESET2 are on the same BWP or different BWPs.

In this example, CORESET1 and CORESET2 correspond to different first information, i.e., different sets of DRX parameters. The terminal monitors only PDCCH on Search Space associated with CORESET1 in an awakening time period of a DRX period corresponding to CORESET 1; the terminal monitors only the PDCCH on the Search Space associated with the core set2 during the awake time period of the DRX cycle corresponding to the core set 2.
