Description

Method and device for detecting downlink control channel, and terminal equipment

Embodiments of the present application relate to the technical field of mobile communications, and in particular, to a method, device, and terminal device for detecting a downlink control channel.

In the new radio (NR, New Radio) system, the network can configure multiple control resource sets (CORESET, Control Resource Set) on each downstream bandwidth part (BWP, Band Width Part), CORESET defines a time frequency The domain resource, specifically, specifies the frequency domain size of CORESET in the frequency domain and the number of consecutive symbols occupied by CORESET in the time domain. At the same time, the next generation Node B (gNB, nextgeneration NodeB) can also associate one or more search spaces (Search Space) to each CORESET to determine the time period for user equipment (UE) To detect the control channel. Among them, each Search Space needs to be associated with a CORESET.

On the other hand, in the NR system, each media access control entity (MAC entity) has a discontinuous reception (DRX, Discontinuous Reception) configuration. It is worth noting that DRX configuration parameters (referred to as DRX parameters) apply to All configured CORESET and Search Space. In a DRX cycle, if the UE is in the awake state, the UE needs to blindly detect all possible positions of the physical downlink control channel (PDCCH); if the PDCCH is detected at any possible position of the PDCCH , And if the PDCCH schedules a new uplink or downlink transmission, the timer — drx-InactivityTimer will be restarted, thereby extending the duration of the awake state.

In the current configuration, Search Space and CORESET are configured through RRC signaling. For Search Space with a relatively small configuration period, the UE needs to frequently blindly pick up the PDCCH, resulting in increased terminal energy consumption; for Search with a relatively long configuration period Space, the UE does not need to frequently blindly pick up the PDCCH, but may sacrifice scheduling flexibility.

Step 201: The terminal device obtains the first information.

In the embodiment of the present 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 computer, a car terminal, a wearable device, and the like.

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

A first time parameter, the first time parameter is used to determine the start time of the DRX cycle;

Further, for the first time parameter in the above solution, the start 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 of the wake-up state (that is, the first time) may be any time. In one example, the start time corresponding to the wake-up state of the terminal device in the DRX cycle (that is, the first time) ) Corresponds to an integer multiple of the period of the search space. For example, the period of Search Space is configured as 1 slot. Assuming that the start time of the terminal device in the DRX cycle can be 4 times the period of the Search Space, then the terminal device needs to be in slot 0 ,4,8,...Start to detect the PDCCH.

Here, the time unit is a subframe, or time slot, or symbol, or short transmission time interval (STTI).

A specific implementation, the first time parameter can be represented by drx-StartOffset, the second time parameter corresponding functions can be implemented by a timer drx-onDurationTimer, parameters corresponding to the third time by a timer function drx- InactivityTimer implementation, the corresponding four time parameters can be represented by drx-ShortCycle , and the fifth time parameter can be represented by drx-LongCycle .

In the embodiment of the present application, the correspondence 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 all search spaces associated with the one control resource set; or, the first information corresponds to multiple control resource sets and the multiple control resources Part of the search space or all search spaces associated with the set correspond.

For example, suppose that the SearchSpace associated with CORESET1 is SS1, SS2, the SearchSpace associated with CORESET2 is SS3, and the SearchSpace associated with CORESET3 is SS4, SS5, SS6. In one example, the first information configured by the network side for the terminal device corresponds to CORESET1 and SS1 . In another example, the first information configured by the network side for the terminal device corresponds to CORESET3 and SS4, SS5, and SS6. In yet another example, the first information configured by the network side for the terminal device corresponds to CORESET1 and SS1, and CORESET2 and SS3.

In the embodiment of the present application, when the at least one control resource set includes multiple control resource sets: different control resource sets in the multiple control resource sets are configured on the same bandwidth part BWP; or, the multiple Different control resource sets of each control resource set are configured on different BWP.

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

In the embodiment of the present application, the first information is radio resource control (RRC, Radio Resource Control) signaling, or downlink control information (DCI, Downlink Control Information) signaling, or media access control control unit (MAC CE, Media Access Control Control Element), or the first sequence (can be any sequence).

1) When the first information is RRC signaling, the first information includes a set of discontinuous reception DRX parameters or multiple sets of DRX parameters; the terminal device according to the set of DRX parameters, in the set Detecting at least one control resource set corresponding to the DRX parameter and at least one search space associated with the at least one control resource set to detect a downlink control channel; or, according to the multiple sets of DRX parameters, the terminal device selects the multiple sets of DRX parameters A downlink control channel is detected on at least one control resource set corresponding to each and at least one search space associated with the at least one control resource set.

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

In an embodiment, when the terminal is configured with the multiple sets of DRX parameters, the terminal determines at least one set of DRX parameters in an activated state, and the at least one set of DRX parameters in the activated state respectively corresponds to Detecting 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; and/or, the terminal determining at least one set of DRX parameters in a deactivated state, and in the deactivated state At least one control resource set corresponding to at least one set of DRX parameters in the state and at least one search space associated with the at least one control resource set cancel the detection of the downlink control channel. Here, the terminal device obtains second information, and the second information is used to determine at least one set of DRX parameters that need to be activated, and/or at least one set of DRX parameters that need to be activated.

In the above solution, each set of DRX parameters in the multiple sets of DRX parameters corresponds to one piece of index information; wherein, 1) the second information is DCI signaling or MAC CE, and the DCI signaling or MAC CE Index information corresponding to at least one set of DRX parameters that need to be activated, and/or index information corresponding to at least one set of DRX parameters that need to be activated, 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 to the terminal device through DCI signaling or MAC CE, namely index1, index2, and index3, 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. Based on this, the terminal device determines three sets of DRX parameters that need to be started.

As another example, the terminal device obtains a certain sequence, which corresponds to the DRX index of a set of DRX parameters (such as an orthogonal relationship), and the terminal device can determine the DRX index of a set of DRX parameters based on the sequence, thereby determining A set of DRX parameters that need to be started or de-started. Here, a sequence is used as an example for explanation. It is not limited to this. The situation of multiple sequences is the same as a sequence. Through multiple sequences, it is possible to determine whether to start or de-start. The DRX index of multiple sets of DRX parameters to determine the multiple sets of DRX parameters that need to be activated or deactivated.

In the above solution of the embodiment of the present application, the network side may configure a set of DRX parameters or multiple sets of DRX parameters for the terminal; if the first information includes only one set of DRX parameters, the network side may change different DRX through RRC reconfiguration messages The parameters enable the terminal to monitor different search spaces; if the first information includes multiple sets of DRX parameters, then each set of DRX parameters may correspond to at least one control resource set and search space. The terminal only monitors the control channel in the corresponding search space during the wake-up period determined by the corresponding set of DRX parameters. Further, in the case where the network side configures multiple sets of DRX parameters for the terminal and the correspondence between each set of DRX parameters and the search space, the network side can also activate or deactivate one or more sets of DRX parameters through MAC CE or DCI. If a set of DRX parameters is started, the terminal does not need to monitor the downlink control channel of the corresponding search space.

2) When the first information is DCI signaling or MAC CE, the first information includes first indication information, and the first indication information is used to indicate index information of a group of DRX parameters (that is, the Index information of a set of DRX parameters); the terminal device determines at least one set 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 set of DRX parameters The terminal device determines the first period of time during which the terminal device is in the awake state in the DRX cycle according to the set of DRX parameters, and the at least one control resource set and the A downlink control channel is detected on at least one search space associated with at least one control resource set.

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

4) When the first information is a first sequence, the first sequence has a corresponding relationship with a set of DRX parameters; the terminal device determines at least one control resource set and the at least one according to the first sequence A set of DRX parameters corresponding to at least one search space associated with the control resource set; the terminal device determines, according to the set of DRX parameters, the first time period during which the terminal device is in the awake state in the DRX cycle, and Detect the downlink control channel on the at least one control resource set and at least one search space associated with the at least one control resource set within the first time period.

5) When the first information is a first sequence, the first sequence has a corresponding relationship with at least one control resource set and at least one search space associated with the at least one control resource set; the terminal device according to the The first sequence is to determine at least one search space associated with the at least one control resource set and the at least one control resource set; the terminal device is on at least one search space associated with the at least one control resource set and the at least one control resource set Check the downstream control channel.

In the above solution, a set of DRX parameters can be directly configured through RRC signaling, and then the downlink control channel on the corresponding search space is monitored based on the DRX parameters. You can also configure an indication message through DCI signaling or MAC CE to indicate a set of DRX parameters that need to be started. Here, the terminal obtains multiple sets of DRX parameters in advance (which can be obtained through RRC signaling). After receiving the indication information, it starts A set of DRX parameters, and then monitor the downlink control channel on the corresponding search space based on the DRX parameters. It is also possible to configure another indication information through DCI signaling or MAC CE to indicate the search space to be monitored. Here, the terminal obtains a set of DRX parameters in advance, and after receiving the indication information, monitors the search indicated by the indication information based on the DRX parameters Downstream control channel in space.

Specifically, a DRX cycle includes two time periods, namely On Duration (the terminal device is in the awake state) and Opportunity for DRX (the terminal device is in the sleep state), where the On Duration period is before the Opportunity for DRX, the terminal The device starts to detect the PDCCH at the start time of the DRX cycle (determined based on the first time parameter) and continues to detect the PDCCH within the On Duration period; 1) If the terminal device successfully decodes to a downlink control channel And the downlink control channel schedules a new transmission of data, then start the timer drx-InactivityTimer (corresponding to the third time parameter), before the timer expires, the terminal device will continue to remain in the awake state and detect the PDCCH, After the timer expires, the terminal device enters the sleep state until the start time of the next DRX cycle comes to re-enter the wake-up state. 2) If the terminal device does not successfully decode to a downlink control channel and the downlink control channel schedules a new transmission of data, at the end of the On Duration period, the terminal device enters a sleep state until the beginning of the next DRX cycle Time to re-enter the wake-up state.

The technical solutions of the embodiments of the present application will be illustrated below through specific application examples.

Application example one

Referring to FIG. 3, the network configures two CORESETs on a downlink BWP for a UE, namely CORESET1 and CORESET2, each CORESET has an associated Search Space, and the period of the Search Space associated with CORESET1 is associated with the Search Space associated with CORESET2. The cycle is different.

In this example, CORESET2 corresponds to the first information, which is the same set of DRX parameters. The set of DRX parameters may include the start time of the DRX cycle. The UE starts to detect the PDCCH at the start time of the DRX cycle. Here, the start time is an integer multiple of the period corresponding to the Ssearch Space. For example, the period of the Search Space is configured as 1 slot, the start time can be 4 times of the cycle, 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 (such as DCI).

The UE continues to detect the PDCCH during the On Duration period; 1) If the terminal device successfully decodes to a downlink control channel and the downlink control channel schedules a newly transmitted data, a timer drx-InactivityTimer is started (corresponding to the third Time parameter), before the timer expires, the terminal device will continue to remain in the awake state and detect the PDCCH. After the timer expires, the terminal device enters the sleep state until the start time of the next DRX cycle Re-enter the wake-up state. 2) If the terminal device does not successfully decode to a downlink control channel and the downlink control channel schedules a new transmission of data, at the end of the On Duration period, the terminal device enters a sleep state until the beginning of the next DRX cycle Time to re-enter the wake-up state.

Application example 2

The network configures two CORESETs for a UE. Refer to Figure 4, which are CORESET1 and CORESET2 respectively. Each CORESET is associated with a Search Space. The period of the Search Space associated with CORESET1 is different from the period of the Search Space associated with CORESET2. Here, it is not limited whether CORESET1 and CORESET2 are on the same BWP or different BWP.

In this example, CORESET1 and CORESET2 correspond to different first information, that is, a different set of DRX parameters. During the wake-up period of the DRX cycle corresponding to CORESET1, the terminal only monitors the PDCCH on the Search Space associated with CORESET1; during the wake-up period of the DRX cycle corresponding to CORESET2, the terminal monitors only the PDCCH on the Search Space associated with CORESET2.
