Description

Method for allocating candidate PDCCH, terminal and network side equipment

Technical Field

The application belongs to the technical field of wireless communication, and particularly relates to a method for allocating candidate PDCCHs, a terminal and network side equipment.

Background

A Physical Downlink Control Channel (PDCCH) in a New Radio (NR) carries Downlink Control Information (DCI). The DCI is mapped to a physical resource with Control Channel Elements (CCEs) as a unit, that is, a PDCCH candidate, after a series of scrambling, modulation, and coding processes. In addition, the network side configures a plurality of Search Space (SS) sets (sets), which generally include two types of SS sets: one is common SS (CSS) set and the other is user-specific SS (USS) set. Each SS set includes a plurality of PDCCH candidates.

In order to reduce the implementation complexity of the terminal, the NR system specifies the maximum PDCCH candidate blind detection number (BD) and the maximum number of non-overlapping CCEs per unit time for the connected terminal.

However, in the face of introducing more and more Radio Resource Control (RRC) non-connected state transmissions, how to allocate candidate PDCCHs of different search space sets for terminals in a non-connected state (including RRC idle terminals and RRC non-active terminals) becomes an urgent problem to be solved.

The method for allocating PDCCH candidates according to the embodiments of the present application is described in detail below with reference to the accompanying drawings.

Fig. 2 shows a flowchart of a method for allocating PDCCH candidates in this embodiment, where the method 200 may be performed by a terminal. In other words, the method may be performed by software or hardware installed on the terminal. As shown in fig. 2, the method may include the following steps.

S210, the terminal in the non-connection state allocates candidate PDCCHs of a first SS set in a first time unit according to a first rule; wherein the first rule is used to indicate a mapping priority of the first SS set, and the first time unit includes: time slots and/or listening spans (spans).

It should be noted that the purpose of allocating the PDCCH candidate of the first SS set in the first time unit is for monitoring, that is, allocating the PDCCH candidate of the first SS set in the first time unit for monitoring.

It should be noted that another expression of "the first rule is used to indicate the mapping priority of the first SS set" is that the first rule is used to indicate the mapping priority of the first SS set in the first time unit.

In the embodiment of the present application, at least one SS set may be included in the first SS set, and the first rule indicates a mapping priority of one or more SS sets or all SS sets therein.

In this embodiment of the present application, the first rule may be configured or agreed by a network side device, or the terminal in the non-connected state determines itself.

In the current standard research, a new CSS set and/or USS set is introduced in an idle/inactive (inactive) state. For example, the CSS set carrying PEIPDCCH. Therefore, a plurality of CSSs and USSs in the same slot or span may collide with each other or exceed the BD capability of the UE, and therefore, in the RRCidle/inactive state, a problem of how to allocate candidate PDCCHs combined in different search spaces needs to be further solved.

In the embodiment of the application, through the first rule, the allocation process of the terminal in the non-connected state to the candidate PDCCH can be determined, the problems that the maximum relevant processing capacity of the terminal in the non-connected state is exceeded and the like are solved, and the performance of scheduling transmission is improved.

In the present embodiment, the first SSset includes, but is not limited to, at least one of a first common search space set (CSS set) and a first dedicated search space set (USS set).

Optionally, the first CSS set may include at least one of:

(1) CSS set for carrying paging advanced indication (PEI) PDCCH;

(2) CSS set for carrying Multicast Broadcast Service (MBS) PDCCH;

(3) CSS set for carrying Small Data Transmission (SDT) PDCCH;

(4) Type 0PDCCH (Type 0-PDCCH) CSS set; the Type0-PDCCH CSS set is used to carry first-format DCI, where CRC of the first-format DCI is scrambled by System Information radio Network Temporary Identity (SI-RNTI) and is used to schedule a System Information Block (SIB 1) message.

(5) Type0A PDCCH (Type 0A-PDCCH) CSS set; type0A-PDCCH CSS set is used for carrying second format DCI, wherein CRC of the second format DCI is scrambled by SI-RNTI and is used for scheduling SIB messages except SIB1 messages.

(6) Type 1PDCCH (Type 1-PDCCH) CSS set; the Type1-PDCCH CSS set is used for carrying third-format DCI, wherein CRC of the third-format DCI is scrambled by Random Access RNTI (Random Access RNTI, RA-RNTI) or temporary scheduling Cell RNTI (TC-RNTI).

(7) Type 2PDCCH (Type 2-PDCCH) CSS set; the Type2-PDCCH CSS set is used for carrying fourth-format DCI, wherein the CRC of the fourth-format DCI is scrambled by Paging RNTI (P-RNTI).

(8) Type 3PDCCH (Type 3-PDCCH) CSS set. The Type3-PDCCH CSS set is used for carrying fifth-Format DCI, wherein the CRC of the fifth-Format DCI is scrambled by an interrupt RNTI (INT-RNTI), a Slot Format Indication RNTI (Slot Format Indication RNTI, SFI-RNTI), a transmission Power Control-Physical Uplink Shared channel RNTI (Transmit Power Control-Physical Uplink Shared channel RNTI, TPC-PUSCH-RNTI), a transmission Power Control-Physical Uplink Control channel RNTI (Transmit Power Control-Physical Uplink Control channel RNTI, TPC-PUSCH-RNTI), or a transmission Power Control-Sounding Reference symbol (Transmit Power Control-Sounding Reference Symbols-RNTI, TPC-PUSCH-RNTI), and the SRS is Configured by a Cell RNTI (Cell RNTI, C-RNTI), a Modulation and coding scheme Cell RNTI (Modulation and coding scheme C-RNTI), a C-Scheduling RNTI (C-RNTI), or a Scheduling CS-RNTI.

Optionally, the first USS set includes, but is not limited to, a USS set for carrying an SDT PDCCH.

In one possible implementation, the first rule is further for indicating at least one of:

(1) The terminal in the non-connected state is not allowed to abandon the allocation of the PDCCH candidate for the second SS set.

For example, the first rule may indicate that for a terminal in the non-connected state, its second SS set may not be relinquished for allocation due to exceeding the maximum processing capacity. That is, the terminal in the non-connected state must allocate the PDCCH candidate of the second sset. Optionally, the network side device may be configured to ensure that the second SS set is not dropped by the terminal for exceeding the maximum processing capacity. That is, the terminal must perform the assignment of the PDCCH candidate for the second sset in the first time unit.

For example, the second SS set may contain at least one of: CSSset (briefly named peicsset) for carrying PEI PDCCH, CSSset (briefly named sdtcsset) for carrying SDTPDCCH. Alternatively, the second SS set may be a CSS set other than the CSS set used to carry the PEI PDCCH.

(2) Allowing the terminal in the non-connected state to give up allocation of the candidate PDCCH of the third SS set.

For example, the network side device may configure or agree to allow the third CSS set to be relinquished from allocation by the idle/inactive state terminal.

Wherein the second SSset and the third SSset are included in the first SSset. It should be noted that the inclusion of the second sscet and the third sscet in the first sscet means that the second sscet and the third sscet belong to the first sscet.

In one embodiment, the third SS set may include at least one of:

(a) CSS set for carrying PEI PDCCH;

(b) CSS set for carrying MBS PDCCH;

(c) CSS set for carrying SDT PDCCH;

(d) The first USS set.

In the above possible implementation, one SS set can only be one of the second SS set or the third SS set, and cannot belong to both the second SS set and the third SS set.

In one possible implementation, in a case that the first rule is further used to instruct the terminal in a non-connected state not to be allowed to abandon allocation of a PDCCH candidate for a second SS set and/or to allow the terminal in a non-connected state to abandon allocation of a PDCCH candidate for a third SS set, the mapping priority of the first SS set comprises any one of the following in order from high to low:

(1) The second SS set, SS sets other than the second SS set;

for example, in the case where the first rule indicates that the terminal in the non-connected state is not allowed to relinquish allocation of a PDCCH candidate for a second SS set, the mapping priority of the second SS set is set to a high priority in order to guarantee allocation of a PDCCH candidate for the second SS set, which is preferentially allocated to the PDCCH candidate for the second SS set.

(2) A SS set other than the third SS set, the third SS set;

for example, in the case where the first rule indicates that the terminal in the non-connected state is allowed to relinquish allocation of a PDCCH candidate for the third sscet, since the PDCCH candidate for the third sscet can be relinquished for allocation, the mapping priority for the third SS set may be set to the lowest priority, i.e., PDCCHs candidates for sscets other than the third sscet are allocated first and then the PDCCH candidates for the third sscet are reallocated.

(3) The second SS set, the third SS set.

For example, in the case where the first rule indicates that the terminal in the non-connected state is not allowed to relinquish allocation of a PDCCH candidate for the second SS set, and that the terminal in the non-connected state is allowed to relinquish allocation of a PDCCH candidate for the third SSset, the mapping priority for the second SS set may be set to be higher than the priority for the third SS set.

In the above possible implementation manner, the first rule may implicitly indicate the priority of the second SS set and/or the third SS set by indicating that the terminal in the non-connected state is not allowed to abandon the assignment of the PDCCH candidate for the second SS set and/or allowing the terminal in the non-connected state to abandon the assignment of the PDCCH candidate for the third SS set.

Optionally, it may be determined whether to allow the non-connected terminal to abandon allocation of candidate PDCCHs for carrying CSS sets of a PEI PDCCH and/or mapping priority of CSS sets for carrying a PEI PDCCH according to whether paging PDCCH monitoring is performed when the non-connected terminal does not detect PEI. For example, in one possible implementation, in a case where the network configuration or protocol stipulates that the terminal in the non-connected state does not perform paging PDCCH monitoring when no PEI is detected, the terminal in the non-connected state is not allowed to abandon allocation of a candidate PDCCH for carrying a PEI PDCCH (the CSS set for carrying the PEI PDCCH belongs to the first SS set), that is, in a case where a second SS set is set, optionally, the second SS set includes a CSS set for carrying the PEI PDCCH; and/or the mapping priority of the CSS set for carrying the PEI PDCCH is higher than at least one of the following: the mapping priority of CSS sets except the CSS sets for carrying the PEI PDCCH and the mapping priority of USS sets.

For example, in a current cell broadcasted by a network side device, if the UE does not detect PEI waking itself, then paging PDCCH monitoring is not performed, in order to ensure that the UE can detect its PEI and avoid paging PDCCH being missed, the terminal in the non-connected state may be set not to be allowed to abandon allocation of candidate PDCCHs of CSS sets used for carrying PEI PDCCHs, and/or the mapping priority of the CSS sets used for carrying PEI PDCCHs is set to be higher than at least one of the following: and the mapping priorities of the CSS sets except the CSS sets for carrying the PEI PDCCH and the mapping priorities of the USS sets. When the terminal in the non-connected state allocates the candidate PDCCH in the current first time unit, firstly allocating CSS sets (which may be referred to as PEI CSS sets) for carrying the PEI PDCCH, and re-allocating at least one of the following: CSS set and USS set except the CSS set for carrying the PEI PDCCH.

In another possible implementation manner, in the case that the network configures or agrees to agree that the terminal in the non-connected state monitors paging PDCCH when no PEI is detected, the terminal in the non-connected state is allowed to abandon allocation of candidate PDCCH for carrying CSS set of PEI PDCCH, that is, in the case that a third SS set is set, optionally, the third SS set comprises CSS set for carrying PEI PDCCH; and/or the mapping priority of the CSS set for carrying the PEI PDCCH is lower than at least one of the following: the mapping priority of CSS sets except the CSS sets for carrying the PEI PDCCH and the mapping priority of USS sets.

For example, the relevant behavior of the network side device broadcasting the current cell and adopting the UE to detect the PEI is: and if the UE does not detect the PEI which wakes up the UE, performing paging PDCCH monitoring. Since the UE monitors pagengPDCCH even if the UE does not detect PEI waking itself, the UE is not influenced to monitor pagengPDCCH even if the CSS set used for carrying PEI PDCCH is abandoned for allocation, so that the non-connected terminal can be allowed to abandon the allocation of candidate PDCCH used for carrying CSS set of PEI PDCCH and/or the mapping priority of CSS set used for carrying PEI PDCCH is set to be lower. For example, the agreement may agree that PEI CSS sets may be allowed to be relinquished for exceeding the maximum associated processing capacity (i.e., maximum BD or CCE number limit), and that the mapping priority of PEI CSS sets is less than that of USS sets. When the UE allocates PDCCH candidate in the current slot, the RRC Inactive UE allocates CSS sets except the PEI CSS first, reallocates the USS set and then allocates the PEI CSS, but the UE judges that the UE allocates the PEI CSS and then exceeds the capability limit of the maximum number of non-overlapping CCEs, and discards the PEI CSS sets in the current slot, namely abandons the allocation of candidate PDCCHs of the PEI CSS sets.

In one possible implementation, the mapping priority of the CSS set used to carry the PEI PDCCH is lowest. For example, the network side device configures or agrees to agree that the mapping priority of the CSS set used to carry the PEI PDCCH is the lowest, for example, if the terminal finds that the maximum BD or CCE number limit would be exceeded if the PEI CSSset is reallocated before the PEI CSSset is allocated, the PEI CSSset is discarded.

In one possible implementation, the mapping priorities of the first SS sets further include, in order from high to low, at least one of:

(1) The CSS set is used for carrying the PEI PDCCH, the first USS set and the CSS set is used for carrying the PEI PDCCH;

for example, when the terminal in the non-connected state allocates a candidate PDCCH of a first SS set in a first time unit, first allocates CSS sets other than the PEI CSS set; redistributing the USS set; finally PEI CSS set is assigned. And if the UE judges that the number limit of the maximum BD or the maximum non-overlapping CCEs of the UE exceeds the number limit of the maximum BD or the maximum non-overlapping CCEs, discarding the BD or the maximum non-overlapping CCEs according to the priority. For example, PEI CSS set priority is less than SDT USS set, and PEI CSS set is discarded if the PEI CSS set is redistributed and the maximum BD or CCE number limit is exceeded when the UE is distributed with the SDT USS set.

The mapping priority order may be indicated by a first rule, for example, configured by a network side device or agreed by a protocol.

(2) CSS set except the CSS set used for carrying the PEI PDCCH, the CSS set used for carrying the PEI PDCCH and the first USS set;

for example, when the terminal in the non-connected state allocates the candidate PDCCH of the first SS set in the first time unit, the CSS sets other than the CSS set used for carrying the PEI PDCCH are allocated first, the CSS set used for carrying the PEI PDCCH is reallocated, and finally the first USS set is allocated. And if the UE judges that the number limit of the maximum BD or the maximum non-overlapping CCE of the UE exceeds the number limit of the maximum BD or the maximum non-overlapping CCE, discarding the BD or the maximum non-overlapping CCE in sequence according to the priority. For example, the mapping priority of the SDT USS set is less than the PEI CSS set, and when the UE finds that the maximum BD or CCE number limit is exceeded if the SDT USS set is redistributed after the PEI CSS set is distributed, the SDT USS set is discarded.

The mapping priority order may be indicated by a first rule, for example, configured by the network side device or agreed by a protocol.

(3) The first CSS set and the first USS set.

(4) The first USS set, the first CSS set.

In a possible implementation manner, the network side device may broadcast the mapping priority of the first CSS set relative to the first USS set, and may configure or agree with the priorities of (1) and (2) in advance, and the terminal in the non-connected state determines whether to adopt the mapping priority order of (1) or (2) according to the content of the broadcast of the network side device. For example, if the mapping priority of the first CSS set is higher than the mapping priority of the first USS set as broadcast by the network side device, the terminal in the non-connected state may determine to adopt the mapping priority order of (2) above. Alternatively, the network side device may broadcast the mapping priority order of all SS sets, for example, broadcast the priority order described in (1) or (2) above.

Alternatively, the terminal in the non-connected state may determine the mapping priority of the first CSS set relative to the first USS set by itself, so as to determine whether to adopt the mapping priority order of (1) or (2). For example, in a case that the network side device configures or agrees that the terminal in the non-connected state performs paging PDCCH monitoring when the terminal in the non-connected state does not detect PEI, the terminal in the non-connected state may determine to adopt the mapping priority order of (1); when the network side device configures or agrees that the terminal in the non-connected state does not detect PEI, the terminal in the non-connected state may determine to adopt the mapping priority order of (2) above without monitoring the paging PDCCH.

In one possible implementation, the mapping priority of the fourth SS set is agreed by network configuration or protocol, wherein the fourth SS set is included in the first SS set. For example, the fourth SS set may include the CSS set used to carry the PEI PDCCH. In addition, the network side device may notify the terminal in the non-connected state through broadcasting an SIB message, where the mapping priority of the CSS set used for carrying the PEI PDCCH is described.

In one possible implementation manner, the allocating, by the terminal in the non-connected state, a PDCCH candidate of a first search space set SS set in a first time unit according to a first rule includes:

the terminal in the non-connection state sequentially allocates the candidate PDCCHs of the first SS set from high to low according to the mapping priority of the first SS set;

wherein, before a candidate PDCCH of a target SS set is allocated, if it is determined that the candidate PDCCH of the target SS set is to result in exceeding the maximum processing capability of the terminal in a non-connected state, the candidate PDCCH of the target SS set and a fifth SS set are abandoned; wherein the mapping priority of the fifth SS set is lower than the mapping priority of the target SS set, and the first SS set comprises the target SS set and the fifth SS set.

For example, the mapping priority of the SDT USS set is less than the PEI CSS set, and when the UE finds that the maximum BD or CCE number limit is exceeded if the SDT USS set is redistributed after the PEI CSS set is distributed, the SDT USS set is discarded.

Optionally, the maximum processing capability of the terminal in the unconnected state includes: a maximum number of candidate PDCCHs within a first time unit of support; and/or a maximum number of non-overlapping Control Channel Elements (CCEs) within a supported first time unit.

In a specific application, the demodulation process of the PDCCH candidates (PDCCH candidates) carrying DCI by the terminal may be: the terminal finds the initial position of the CCE, tries different aggregation levels at the initial position of the CCE, intercepts and decodes the guessed DCI length, uses corresponding Radio Network Temporary Identifiers (RNTIs) and CCE information to carry out Cyclic Redundancy Check (CRC) on different expected information terminals, and if the CRC is successful, the terminal determines that the information is required by the terminal, which is called a blind check process. In this process, the number of attempts to decode DCI by the terminal is the number of blind detections. Each CCE location of PDCCH candidates may be calculated in a predetermined manner. The starting CCE locations of all PDCCH candidates of a certain PDCCH channel are related to parameters such as aggregation level, search space type, subframe number, total number of available CCEs, RNTI, etc. of the PDCCH channel.

By the method provided by the embodiment of the application, the terminal in the non-connected state can allocate the candidate PDCCH of the first SS set in the first time unit according to the first rule, so that the allocation process of the terminal in the non-connected state to the candidate PDCCH is determined, the problems of exceeding the maximum relevant processing capacity of the terminal in the non-connected state and the like are avoided, and the performance of scheduling transmission is improved.

Fig. 3 shows a flowchart of a PDCCH monitoring method provided in an embodiment of the present application, where the method 300 may be performed by a terminal. In other words, the method may be performed by software or hardware installed on the terminal, as shown in fig. 3, and the method 300 may include the following steps.

S310, under the condition that the terminal does not need to monitor PEI, the terminal determines the monitoring action of the paging PDCCH. Wherein the monitoring behavior of the pagengPDCCH comprises any one of the following: monitoring a paging PDCCH; monitoring of the paging PDCCH is not performed.

In the embodiment of the present application, the terminal may be a connected terminal, for example, an RRC connected UE, or may also be a non-connected terminal, for example, an RRCidle UE or an RRC inactive UE. The specific examples of the present application are not limited thereto.

In the technical scheme provided by the embodiment of the application, the terminal can determine the monitoring action of the paging PDCCH and execute the monitoring action under the condition that the PEI does not need to be monitored.

In one possible implementation manner, the determining, by the terminal, a monitoring behavior of a paging PDCCH includes: and determining whether the terminal monitors the paging PDCCH or not according to the configuration of the network side equipment.

Or, the terminal may also determine the monitoring behavior of the paging PDCCH without monitoring the PEI, for example, if the network side device configuration or the protocol agrees that the UE does not detect the PEI that wakes up itself, then the UE performs the paging PDCCH monitoring, and if the terminal does not need to monitor the PEI, then the terminal performs the paging PDCCH monitoring. And when the network side equipment is configured or agreed by a protocol, the terminal in the non-connection state does not monitor paging PDCCH under the condition that the paging PDCCH is monitored when the PEI is not detected, and does not monitor the paging PDCCH under the condition that the PEI does not need to be monitored by the terminal.

In one possible implementation, the terminal does not need to listen to PEI in the case of at least one of the following:

(1) The terminal does not allocate candidate PDCCHs for carrying CSS sets of the PEI PDCCH;

(2) Modifying the transmission direction of the time unit where the PEI is located;

(3) PEI collides or overlaps with other channels or signals. For example, PEI collides with or overlaps with other transmissions (overlaps) that have higher priority than PEI detection. Among other transmissions, other transmissions include, but are not limited to: at least one of receive, detect, measure, or transmit.

Fig. 4 is a flowchart illustrating a method for configuring a search space set according to an embodiment of the present application, where the method 400 may be performed by a network-side device. In other words, the method may be performed by software or hardware installed on the terminal, as shown in fig. 4, and the method 400 includes the following steps.

S410, a network side device sends configuration information to a terminal in a non-connected state, where the configuration information includes a first rule, the first rule is used to indicate a mapping priority of a first SS set in a first time unit, and the first time unit includes: time slots and/or listening spans.

The first rule is the same as the first rule in the method 200, that is, the method 400 is a method of configuring, by the network side device, the corresponding network side device according to the first rule in the method 200.

The configuration information may be each possible information configured by the network side device in the method 200, and specifically, refer to the relevant description in the method 200.

Optionally, the first CSS set may include at least one of:

(6) Type 1PDCCH (Type 1-PDCCH) CSS set;

(7) Type 2PDCCH (Type 2-PDCCH) CSS set;

(8) Type 3PDCCH (Type 3-PDCCH) CSS set.

(1) The terminal in the non-connected state is not allowed to give up allocation of the candidate PDCCH for the second SS set.

For example, in order to ensure that the second SS set is not discarded from being allocated by the terminal due to exceeding the maximum processing capability, the network side device may be configured not to allow the terminal in the non-connected state to discard the allocation of the PDCCH candidate for the second SS set. That is, the terminal in the non-connected state must perform the allocation of the PDCCH candidate for the second sscet in the first time unit.

For example, the second SS set may contain at least one of: CSSset for carrying PEI PDCCH, CSS set for carrying SDT PDCCH. Alternatively, the second SS set may be a CSS set other than the CSS set used to carry the PEI PDCCH.

(2) Allowing the terminal in the non-connected state to abandon the allocation of the PDCCH candidate for the third SS set.

For example, the network side device may configure to allow the third CSS set to be relinquished from allocation by the idle/inactive stateful terminal.

Wherein the second SSset and the third SSset are included in the first SSset.

In one embodiment, the third SS set may include at least one of:

(a) CSS set for carrying PEI PDCCH;

(b) CSS set for carrying MBS PDCCH;

(1) The second SS set, SS sets other than the second SS set;

(2) A SS set other than the third SS set, the third SS set;

for example, in the case where the first rule indicates that the terminal in the non-connected state is allowed to relinquish allocation of a PDCCH candidate for the third SSset, since the PDCCH candidate for the third SSset can be relinquished for allocation, the mapping priority of the third SSset may be set to the lowest priority, i.e., PDCCHs candidates for SSsets other than the third SSset are allocated first, and then PDCCHs candidates for the third SSset are reallocated.

(3) The second SS set, the third SS set.

In a possible implementation manner, the configuration information may further indicate whether the terminal in the non-connected state performs paging PDCCH monitoring when the terminal does not detect PEI. In a possible implementation manner, whether paging PDCCH monitoring is performed to determine whether to allow the non-connected terminal to abandon allocation of candidate PDCCHs for carrying CSS sets of the PEI PDCCH and/or determine mapping priority of the CSS sets for carrying the PEI PDCCH may also be determined according to whether the configuration information indicates that the non-connected terminal detects PEI.

Optionally, in a case that the configuration information further indicates that the terminal in the non-connected state does not perform paging PDCCH monitoring when the terminal does not detect PEI, the terminal in the non-connected state is not allowed to abandon allocation of candidate PDCCHs used for carrying CSS sets of PEI PDCCHs; and/or the mapping priority of the CSS set for carrying the PEI PDCCH is higher than at least one of the following: the mapping priority of CSS sets except the CSS sets for carrying the PEI PDCCH and the mapping priority of USS sets.

In another possible implementation manner, in a case that the configuration information further indicates that the non-connected terminal monitors paging PDCCH when no PEI is detected, the non-connected terminal is allowed to abandon allocation of candidate PDCCHs for carrying CSS sets of PEI PDCCHs; and/or the mapping priority of the CSS set for carrying the PEI PDCCH is lower than at least one of the following: the mapping priority of CSS sets except the CSS sets for carrying the PEI PDCCH and the mapping priority of USS sets.

In one possible implementation, the configuration information indicates that the mapping priorities of the first SS sets include at least one of the following in order from high to low:

(1) CSS set except CSS set for carrying PEI PDCCH, first USS set and CSS set for carrying PEI PDCCH.

As described above, the first SS set may include at least one of a first CSS set and a first USS set, and the first CSS set includes the CSS set used for carrying the PEI PDCCH.

Further, the first CSS set may further include at least one of:

The first USS set includes, but is not limited to, a USS set for carrying the SDT PDCCH.

(2) CSS set except CSS set for carrying PEI PDCCH, and first USS set;

(3) A first CSS set, a first USS set;

(4) First USS set, first CSS set.

In one possible implementation manner, the network side device may configure the mapping priority of the first CSS set with respect to the first USS set (i.e., the foregoing (3) or (4), and may configure or agree with the priority of the foregoing (1) and (2) in advance, and the terminal in the non-connected state determines to adopt the mapping priority order of the foregoing (1) or (2) according to the content of the broadcast of the network side device.

In one possible implementation, the first rule indicates that the mapping priority of CSS set for carrying PEI PDCCH is lowest. Namely, the network side device configures the mapping priority of the CSS set for carrying the PEI PDCCH to be the lowest. For example, when the network side device configures or agrees that the terminal in the non-connected state does not detect PEI, paging PDCCH monitoring is performed, and the network side device may configure a first rule indicating that the mapping priority of the CSS set used for carrying the PEI PDCCH is the lowest.

In one possible implementation, the first rule indicates a mapping priority of a fourth SS set, where the fourth SS set is included in the first SS set. For example, the fourth SS set may include the CSS set used to carry the PEI PDCCH. In addition, the network side device may configure the terminal in the non-connected state by broadcasting an SIB message, and the mapping priority of the CSS set for carrying the PEI PDCCH.

By the method provided by the embodiment of the application, the network side equipment can configure the first rule for the search space set allocation for the terminal in the non-connected state, so that the terminal in the non-connected state can allocate the first SS set of the first time unit according to the first rule, the allocation process of the terminal in the non-connected state to the candidate PDCCH is determined, the problems that the maximum related processing capability of the terminal in the non-connected state is exceeded and the like are avoided, and the performance of scheduling transmission is improved.
