Background

A Physical Downlink Control Channel (PDCCH) in the NR carries Downlink Control Information (DCI). The DCI is mapped to physical resources in units of Control Channel Elements (CCEs) after a series of processes of scrambling, modulation, coding, and the like. For each DCI, L ═ 1, 2, 4, 8, or 16 CCEs may be allocated, where the number of CCEs of the DCI is denoted as Aggregation Level (AL). The DCI with AL ═ L will map to a physical Resource (Control Resource set, core set) configured on the network side. Each Component Carrier (CC) or cell may be configured with multiple CORESET and multiple Search Space (SS) sets (sets), each SS set may contain one or more SSs, and the SS sets may be a Common Search Space (CSS) set and a terminal-specific Search Space (USS) set. And the UE blindly descrambles the DCI by using various RNTIs according to the configured CORESET and SS (set), and acquires the scheduling information of each cell.

For each Downlink (DL) Bandwidth Part (BWP) on one serving cell, S ≦ 10 search space sets may be configured, and the network side may configure corresponding parameters for each SS set, for example, DCI formats that the UE needs to detect in each SS set.

Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable.

Wherein, the terminal 11 may also be called as a terminal Device or a User Equipment (UE), the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer) or a notebook Computer, a Personal Digital Assistant (PDA), a palmtop Computer, a netbook, a super-Mobile Personal Computer (UMPC), a Mobile Internet Device (MID), a Wearable Device (Wearable Device) or a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), and other terminal side devices, the Wearable Device includes: bracelets, earphones, glasses and the like.

The following describes in detail a configuration method of a search space set provided in the embodiments of the present application with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Fig. 2 shows a flowchart of a configuration method of a search space set in the embodiment of the present application, and the method 200 may be executed by a network-side device. In other words, the method may be performed by software or hardware installed on the network-side device. As shown in fig. 2, the method may include the following steps.

S210, when configuring an SS set of a terminal, network side equipment configures the SS set to associate one or more RNTIs by indicating parameters of RNTIs associated with the SS set.

In this application, the network side device may configure one or more RNTIs for one SS set, and specifically may determine according to data scheduled by DCI on the SS set.

In a possible implementation manner, in S210, when the network side device configures an SS set of the terminal, the network side device may configure one or more RNTIs for the SS set, where different RNTIs correspond to different SS sets, and RNTIs associated with different SS sets may be the same or different, which is not limited in this application.

Although there may be multiple DCI formats that the UE needs to detect in the same SS set, in general, DCI scrambled by different RNTIs may have different periods, for example, different Broadcast Multicast services (MBS) correspond to different RNTIs, and DCI scheduling different MBS services is generally related to an MBS Service period. Thus, at a certain set (set) of SSs, the UE may only need to detect DCI scrambled with a specific or partial RNTI, rather than trying all possible RNTIs. Therefore, in the embodiment of the present application, when configuring each SS set of the terminal, the network side device may configure an associated RNTI for each SS set at the same time, and when detecting, the UE only needs to detect DCI scrambled by the RNTI associated with the SS set, so that the descrambling complexity of the UE may be reduced.

In a possible implementation manner, when configuring the SS sets of the terminal, the network side device may further configure time domain configuration information of each SS set. For example, detection period, slot offset, slot number, symbol position, and control resource set index (where the number of symbols is configured in the control resource set index), etc.

In another possible implementation manner, when configuring the SS set of the terminal, if the SS set is configured as a common type (i.e., CSS set), the network side device may configure the DCI format detected by the terminal in the SS set to be a predetermined format. For example, if one SS set is configured as a type 3CSS set, the network side device may configure the UE to detect the DCI format within the CSS as: DCI 0_0 and/or DCI 1_ 0; alternatively, at least one of the following DCI formats: DCI 2_0, DCI 2_1, DCI 2_2, DCI 2_3, DCI 2_4, DCI 2_6, where CRC scrambling RNTIs of these DCIs may be specified by a protocol, for example, the RNTI of DCI 0_0 may be Cell radio network temporary identity (Cell RNTI, C-RNTI), Modulation and Coding Scheme Cell RNTI (MCS-C-RNTI), or Configured Scheduling RNTI (CS-RNTI), etc., if Configured by DCI 2_0, Cyclic Redundancy Check (CRC) scrambling may be performed by Slot Format Indication RNTI (SFI-RNTI).

In this embodiment, when configuring configuration information of an SS set of a terminal, a network side device may add a parameter indicating an RNTI associated with the SS set, and configure one or more RNTIs associated with the SS set through the parameter, so that when detecting, the terminal detects downlink control information scrambled by the RNTI associated with the SS set in the SS set, thereby reducing descrambling complexity of the terminal.

Fig. 3 shows a flowchart of a configuration method of a search space in an embodiment of the present application, where the method 300 may be performed by a network-side device. In other words, the method may be performed by software or hardware installed on the network-side device. As shown in fig. 3, the method may include the following steps.

S310, when the network side equipment configures the SS of the terminal, the SS is configured to associate one or more RNTIs by indicating the parameters of the RNTIs associated with the SS.

In this application, the network side device may configure one or more RNTIs for one SS, and specifically may determine according to data scheduled by DCI on the SS.

In a possible implementation manner, in S310, when the network side device configures an SS of the terminal, the network side device may configure one or more RNTIs for the SS, where different RNTIs correspond to different SSs, and RNTIs associated with different SSs may be the same or different, and the present application is not limited in this embodiment.

Although there may be multiple DCI formats that the UE needs to detect in the same SS, in general, DCI scrambled by different RNTIs may have different periods, for example, different Broadcast Multicast services (MBS) correspond to different RNTIs, and DCI scheduling different MBS services is generally related to an MBS Service period. Thus, at a certain SS, the UE may only need to detect DCI scrambled with a specific or partial RNTI, rather than trying all possible RNTIs. Therefore, in the embodiment of the present application, when configuring each SS of the terminal, the network side device may configure an associated RNTI for each SSt at the same time, and when detecting, the UE only needs to detect DCI scrambled by the RNTI associated with the SS, so that the descrambling complexity of the UE may be reduced.

In a possible implementation manner, when configuring the SSs of the terminal, the network side device may further configure time domain configuration information of each SS. For example, detection period, slot offset, slot number, symbol position, and control resource set index (where the number of symbols is configured in the control resource set index), etc.

In another possible implementation manner, when configuring the SS of the terminal, if the SS is configured as a common type (i.e., CSS), the network side device may configure the DCI format detected by the terminal in the SS to be a predetermined format. For example, if one SS is configured as a type 3CSS, the network side device may configure the UE to detect the DCI format within the CSS as: DCI 0_0 and/or DCI 1_ 0; alternatively, at least one of the following DCI formats: DCI 2_0, DCI 2_1, DCI 2_2, DCI 2_3, DCI 2_4, DCI 2_6, where CRC scrambling RNTIs of these DCIs may be specified by a protocol, for example, the RNTI of DCI 0_0 may be Cell radio network temporary identity (Cell RNTI, C-RNTI), Modulation and Coding Scheme Cell RNTI (MCS-C-RNTI), or Configured Scheduling RNTI (CS-RNTI), etc., if Configured by DCI 2_0, Cyclic Redundancy Check (CRC) scrambling may be performed by Slot Format Indication RNTI (SFI-RNTI).

In the embodiment of the application, when configuring configuration information of an SS of a terminal, a network side device may add a parameter indicating an RNTI associated with the SS, and configure one or more RNTIs associated with the SS through the parameter, so that when detecting, the terminal detects downlink control information scrambled by the RNTI associated with the SS in the SS, thereby reducing descrambling complexity of the terminal.

Fig. 4 is a flowchart illustrating a method for detecting downlink control information in an embodiment of the present application, where the method 400 may be executed by a terminal. In other words, the method may be performed by software or hardware installed on the terminal. As shown in fig. 4, the method may include the following steps.

S410, when detecting a downlink control channel, a terminal detects downlink control information scrambled by a target RNTI in a target SS or a target SS set, wherein the target RNTI is an associated RNTI configured for the target SS or the target SS set by network side equipment through an RNTI parameter associated with the target SS or the target SS set.

In the application, since the network side device configures the associated RNTI for the SS or SS set when configuring the SS or SS set, when the UE wants to detect the downlink control channel, the UE detects the downlink control information scrambled by the RNTI associated with the target SS or target SS set in the target SS or target SS set, thereby reducing the descrambling complexity of the UE.

In one possible implementation manner, after configuring the SS or SS set, the network side device may indicate configuration information of the SS or SS set to the terminal through a high-level parameter, and the terminal may obtain the RNTI associated with the target SS or target SS set according to the configuration information.

In order to further explain the technical solution provided by the present application, a network side device is taken as an example, and the technical solution provided by the embodiment of the present application is described through a specific example.

Example one

In this embodiment, when configuring a certain SS of a terminal, a network side device adds a parameter indicating an RNTI associated with the SS to configuration information of the SS, and configures a value of the parameter as one or more RNTIs associated with the SS.

For example, the network side device may add the RNTIs configuration parameters to the SearchSpace IE, for example:

RNTIs SEQUENCE{

RNTI-1

RNTI-2

…

}

wherein, RNTI-1 and RNTI-2 are specific RNTIs associated with the SS.

Example two

In this embodiment, when configuring a certain SS set of a terminal, a network side device adds a parameter indicating an RNTI associated with the SS set to configuration information of the SS set, and configures a value of the parameter as one or more RNTIs associated with the SS set.

For example, the network side device may add the RNTIs configuration parameters to the SearchSpace set IE, for example:

RNTIs SEQUENCE{

RNTI-1

RNTI-2

…

}

wherein, RNTI-1 and RNTI-2 are specific RNTIs associated with the SS set.

EXAMPLE III

In this embodiment, the network side device high-level parameter indicates configuration information to the UE, where the configuration information includes one or more RNTIs configured by the network side device for an SS or an SS set of the terminal.

Optionally, the configuration information is the SearchSpace IE described in the first embodiment or the SearchSpace set IE described in the second embodiment.

Example four

In this embodiment, a terminal obtains configuration information of a network side device configuring an SS or SS set through a high-level parameter, where the configuration information includes one or more RNTIs configured by the network side device for the SS or SS set of the terminal.

EXAMPLE five

The base station configures a search space set of the terminal, for example, parameters of each search space set may be configured by SearchSpace. The time domain configuration information of the search space set includes a detection period, a slot offset, a slot number, a symbol position, and a control resource set index (where the control resource set index may be configured with a symbol number).

For example, in fig. 5, the detection period of the SS set is 8 slots, the slot offset is 3 slots, the number of slots is 2 slots, the control resource set index corresponds to one CORESET occupying two OFDM symbols, and the symbol positions are OFDM symbol 0 and OFDM symbol 7 in the slot. In the example, the UE detects CORESET every symbol 0 and symbol 7 in the 3 rd slot and the 4 th slot in 8 slot periods, and CORESET occupies 2 OFDM symbols in the time domain.

If the search space set is configured as a type 3CSS, the base station may configure the UE to detect DCI formats such as DCI 0_0 and/or DCI 1_0, or DCI 2_0, DCI 2_1, DCI 2_2, DCI 2_3, DCI 2_4, and DCI 2_6 within the CSS. The scrambled RNTI of the DCI can be specified by a protocol, for example, the RNTI of DCI 0_0 can be C-RNTI, MCS-C-RNTI or CS-RNTI, and if configured by DCI 2_0, the CRC scrambling can be carried out by SFI-RNTI.

In the related art, a network side device configures a DCI format corresponding to each SS set, and a UE needs to detect all RNTIs that may scramble the DCI format in the SS set. And thus the descrambling complexity of the UE may increase.

By adopting the technical scheme provided by the application, the base station can configure the associated RNTI for each SS or SS set (set), and the UE only needs to detect the DCI format scrambled by the corresponding RNTI when detecting the PDCCH.

Optionally, if an SS or an SS set does not configure an RNTI, an RNTI to which the DCI format may correspond is determined according to a predefined manner. For example:

(1) one Type (Type)0PDCCH CSS or CSS set, configured by PDCCH-ConfigSIB1 in MIB or searchSpaceSIB1 in PDCCH ConfigCommon or searchSpaceZero in PDCCH ConfigCommon, CRC of its DCI format on MCG primary cell scrambled by SI-RNTI;

(2) a Type-0A PDCCH CSS or CSS set configured by searchSpaceother Systeminformation in PDCCH ConfigCommon, the CRC of its DCI format on the MCG primary cell being scrambled by SI-RNTI;

(3) a Type-1PDCCH CSS or CSS set configured by RA-SearchSpace in PDCCH ConfigCommon, and CRC of DCI format on the main cell is scrambled by RA-RNTI, MsgB-RNTI or TC-RNTI;

(4) a Type-2 PDCCH CSS or CSS set, which is configured by pagensearchpace in PDCCH ConfigCommon, and the CRC of the DCI format on the MCG main cell is scrambled by P-RNTI;

(5) one Type-3 PDCCH CSS or CSS set, which is configured by SearchSpace in PDCCH Config, searchSpaceType is common, and has a DCI format scrambled by INT-RNTI, SFI-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI, TPC-SRS-RNTI, CI-RNTI or PS-RNTI and C-RNTI, MCS-C-RNTI or CS-RNTI (only applicable to a main cell);

(6) a USS or USS set configured by SearchSpace in the PDCCH Config, searchSpaceType ═ ue-Specific, having a DCI format scrambled by C-RNTI, MCS-C-RNTI, SP-CSI-RNTI, CS-RNTI, SL-CS-RNTI or SL-L-CS-RNTI.

EXAMPLE six

For MBS service data, scheduling may be performed through DCI format X, e.g., DCI format 1_1 or DCI format 2_ Y. Since each MBS service is often periodic, one UE may be interested in multiple MBS services at the same time, i.e. receive data of multiple MBS services at the same time. For example, for MBS service 1, the period is 5 time slots, and the corresponding RNTI is RNTI 1; for MBS service 2, its period is 10 slots, and the corresponding RNTI is RNTI 2. Suppose that both MBS service 1 and MBS service 2 are scheduled by DCI format X, and the base station configures a certain SS set for scheduling the MBS service. According to the related art, the base station may configure one SS set with a detection period of 5 slots and configure the UE to detect the DCI format X at the SS set, and configure one SS set with a period of 10 slots and configure the UE to detect the DCI format X at the SS set. The base station may send the PDCCH for scheduling MBS 1 in the SS set with the detection period of 5 slots and the PDCCH for scheduling MBS 2 in the SS set with the detection period of 10 slots.

However, on the UE side, since the DCI format X may be scrambled by the RNTI1 and the RNTI2, the UE needs to detect the DCI format X scrambled by the RNTI1 and the RNTI2 in the SS set having a detection period of 5 slots, and also needs to detect the DCI format X scrambled by the RNTI1 and the RNTI2 in the SS set having a detection period of 10 slots. Thus increasing the descrambling complexity for the UE.

By adopting the technical scheme provided by the application, the base station can configure the associated RNTI as the RNTI1 when configuring the SS set with the detection period of 5 time slots, and can configure the associated RNTI as the RNTI2 when configuring the SS set with the detection period of 10 time slots. On the UE side, the UE only needs to detect the DCI format X scrambled by the RNTI1 in the SS set with the detection period of 5 time slots, and also only needs to detect the DCI format X scrambled by the RNTI2 in the SS set with the detection period of 10 time slots. Thereby reducing the descrambling complexity of the UE.
