After a series of scrambling, modulation, coding and other processes, DCI will be mapped to physical resources in units of control channel elements (Control Channel Elements, CCE), that is, a candidate PDCCH (PDCCH candidates). In addition, the network side is configured with multiple search space (Search space, SS) sets (sets), generally including two types of SS sets: one is the common search space set (common SS, CSS) set, the other is user-specific Search space set (UE-specific SS, USS) set. Each SS set contains multiple PDCCH candidates.
考虑到硬件能力和时延，监视大量的PDCCH candidates或CCE将增加终端的复杂度，为了降低终端的实现复杂度，NR***规定了连接态终端在单位时间内的最大PDCCH candidate盲检数(BD)以及最大不重叠的CCE数。Considering the hardware capability and time delay, monitoring a large number of PDCCH candidates or CCEs will increase the complexity of the terminal. In order to reduce the implementation complexity of the terminal, the NR system specifies the maximum number of blind PDCCH candidates (BD) for the connected terminal in unit time. ) and the maximum number of non-overlapping CCEs.
然而，面对引入越来越多的无线资源控制(Radio Resource Control，RRC)非连接态传输，针对处于非连接态的终端(包括RRC空闲态终端和RRC非激活态终端)如何分配不同搜索空间集的候选PDCCH，成为亟待解决的问题。However, in the face of the introduction of more and more Radio Resource Control (RRC) disconnected state transmissions, how to allocate different search spaces for terminals in disconnected state (including RRC idle state terminals and RRC inactive state terminals) The candidate PDCCH of the set has become an urgent problem to be solved.

The Type3-PDCCH CSS set is used to carry the fifth format DCI, wherein the CRC of the fifth format DCI consists of an interrupt RNTI (Interruption RNTI, INT-RNTI), a slot format indication RNTI (Slot Format Indication RNTI, SFI-RNTI), Transmit Power Control-Physical Uplink Shared Channel RNTI (Transmit Power Control-Physical Uplink Shared Chanel RNTI, TPC-PUSCH-RNTI), Transmit Power Control-Physical Uplink Control Channel RNTI (Transmit Power Control Physical Uplink Control Chanel RNTI, TPC-PUSCH- RNTI), or transmit power control-sounding reference symbol RNTI (Transmit Power Control-Sounding Reference Symbols-RNTI, TPC-SRS-RNTI) scrambling, and only for the primary cell, by the cell RNTI (Cell RNTI, C-RNTI), Modulation and coding scheme cell RNTI (Modulation and coding scheme C-RNTI, MCS-C-RNTI), or configuration scheduling RNTI (Configured Scheduling RNTI, CS-RNTI) scrambling.
可选地，所述第一USS set包括但不限于用于承载SDT PDCCH的USS集合。Optionally, the first USS set includes but is not limited to the USS set used to carry the SDT PDCCH.
在一个可能的实现方式中，所述第一规则还用于指示以下(1)和(2)中的至少一项。In a possible implementation manner, the first rule is further used to indicate at least one of the following (1) and (2).
(1)不允许所述处于非连接态的终端放弃对第二SS set的候选PDCCH的分配。(1) The terminal in the disconnected state is not allowed to give up the allocation of the candidate PDCCH of the second SS set.
例如，第一规则可以指示对于处于非连接态的终端，其第二SS set不可以因超过最大处理能力而被放弃分配。也就是说，处于非连接态的终端一定要去分配第二SSset的候选PDCCH。可选地，网络侧设备可以配置以保证所述第二SS set不会因为超过最大处理能力而被终端丢弃分配。也就是说，终端在第一时间单元内必须进行第二SSset的候选PDCCH的分配。For example, the first rule may indicate that for a terminal in a disconnected state, its second SS set may not be relinquished due to exceeding the maximum processing capacity. That is to say, the terminal in the disconnected state must allocate the candidate PDCCH of the second SSset. Optionally, the network side device may be configured to ensure that the second SS set will not be discarded and allocated by the terminal because it exceeds the maximum processing capacity. That is, the terminal must allocate the candidate PDCCH of the second SSset within the first time unit.
例如，第二SS set可以是包含以下至少一项：用于承载PEI PDCCH的CSSset(简称PEICSSset)、用于承载SDT PDCCH的CSS set(简称SDTCSSset)。或者，第二SS set可以是除用于承载PEI PDCCH的CSS set之外的CSS set。For example, the second SS set may include at least one of the following items: a CSSset for carrying PEI PDCCH (PEICSSset for short) and a CSS set for carrying SDT PDCCH (SDTCSSset for short). Alternatively, the second SS set may be a CSS set other than the CSS set used to carry the PEI PDCCH.
(2)允许所述处于非连接态的终端放弃对第三SS set的候选PDCCH的分配。(2) Allow the terminal in the disconnected state to abandon the allocation of the candidate PDCCH of the third SS set.
例如，网络侧设备可以配置或协议约定允许第三CSS set可以被 idle/inactive态终端放弃分配。For example, the network-side device may be configured or agreed in a protocol to allow the third CSS set to be relinquished by idle/inactive terminals.
其中，所述第一SSset中包括所述第二SSset和所述第三SSset。需要说明的是，所述第一SSset中包括所述第二SSset和所述第三SSset指的是第二SSset和第三SSset属于第一SSset。Wherein, the first SSset includes the second SSset and the third SSset. It should be noted that the fact that the first SSset includes the second SSset and the third SSset means that the second SSset and the third SSset belong to the first SSset.
在一种实施例中，所述第三SS set可以包括以下至少一项：In one embodiment, the third SS set may include at least one of the following:
(a)用于承载PEI PDCCH的CSS set；(a) CSS set for carrying PEI PDCCH;
(b)用于承载MBS PDCCH的CSS set；(b) CSS set for carrying MBS PDCCH;
(c)用于承载SDT PDCCH的CSS set；(c) CSS set for carrying SDT PDCCH;
(d)第一USS set。(d) First USS set.
在上述可能的实现方式中，一个SS set只能是第二SS set或第三SS set中的一项，不能同时属于第二SS set和第三SS set。In the above possible implementation manners, an SS set can only be one of the second SS set or the third SS set, and cannot belong to the second SS set and the third SS set at the same time.
在一个可能的实现方式中，在第一规则还用于指示不允许所述处于非连接态的终端放弃对第二SS set的候选PDCCH的分配和/或允许所述处于非连接态的终端放弃对第三SS set的候选PDCCH的分配的情况下，所述第一SS set的映射优先级从高到低的顺序包括以下(1)至(3)中的任一项。In a possible implementation manner, the first rule is further used to indicate that the terminal in the disconnected state is not allowed to give up the allocation of the candidate PDCCH of the second SS set and/or the terminal in the disconnected state is allowed to give up In the case of allocation of candidate PDCCHs of the third SS set, the order of mapping priorities of the first SS set from high to low includes any of the following (1) to (3).
(1)所述第二SS set、除所述第二SS set之外的SS set。(1) The second SS set, SS sets other than the second SS set.
例如，在第一规则指示不允许所述处于非连接态的终端放弃对第二SS set的候选PDCCH的分配的情况下，为了保证第二SS set的候选PDCCH的分配，将所述第二SS set的映射优先级设置为高优先级，所述处于非连接态的终端优先分配第二SS set的候选PDCCH。For example, when the first rule indicates that the terminal in the disconnected state is not allowed to give up the allocation of the candidate PDCCH of the second SS set, in order to ensure the allocation of the candidate PDCCH of the second SS set, the second SS The mapping priority of the set is set to a high priority, and the terminal in the non-connected state is preferentially allocated the candidate PDCCH of the second SS set.
(2)除所述第三SS set之外的SS set、所述第三SS set。(2) SS sets other than the third SS set, the third SS set.
例如，在第一规则指示允许所述处于非连接态的终端放弃对第三SSset的候选PDCCH的分配的情况下，由于第三SSset的候选PDCCH可以被放弃分配，因此，可以将所述第三SS set的映射优先级设置为最低优先级，即先分配除第三SSset之外的SSset的候选PDCCH，然后再分配第三SSset的候选PDCCH。For example, if the first rule indicates that the terminal in the disconnected state is allowed to give up the allocation of the candidate PDCCH of the third SSset, since the allocation of the candidate PDCCH of the third SSset can be abandoned, the third SSset can be given up. The mapping priority of the SS set is set to the lowest priority, that is, the candidate PDCCHs of the SSsets other than the third SSset are allocated first, and then the candidate PDCCHs of the third SSset are allocated.
(3)所述第二SS set、所述第三SS set。(3) The second SS set and the third SS set.
例如，在第一规则指示不允许所述处于非连接态的终端放弃对第二SS set的候选PDCCH的分配、且允许所述处于非连接态的终端放弃对第三SSset的候选PDCCH的分配的情况下，可以将第二SS set的映射优先级设置为高于第三SS set的优先级。For example, when the first rule indicates that the terminal in the disconnected state is not allowed to give up the allocation of the candidate PDCCH of the second SSset, and the terminal in the disconnected state is allowed to give up the allocation of the candidate PDCCH of the third SSset In this case, the mapping priority of the second SS set may be set higher than the priority of the third SS set.
在上述可能的实现方式中，第一规则可以通过指示不允许所述处于非连接态的终端放弃对第二SS set的候选PDCCH的分配和/或允许所述处于非连接态的终端放弃对第三SS set的候选PDCCH的分配，隐式的指示第二SS set和/或第三SS set的优先级。In the above possible implementation manner, the first rule may indicate that the terminal in the disconnected state is not allowed to give up the allocation of the candidate PDCCH of the second SS set and/or allow the terminal in the disconnected state to give up the assignment to the second SS set. The allocation of candidate PDCCHs for the three SS sets implicitly indicates the priority of the second SS set and/or the third SS set.
可选地，可以根据在所述处于非连接态的终端没有检测到PEI时，是否进行寻呼PDCCH监听来确定是否允许所述处于非连接态的终端放弃对用于承载PEI PDCCH的CSS set的候选PDCCH的分配，和/或用于承载PEI PDCCH的CSS set的映射优先级。例如，在一个可能的实现方式中，在网络配置或协议约定所述处于非连接态的终端在没有检测到PEI时，不进行寻呼PDCCH监听的情况下，不允许所述处于非连接态的终端放弃对用于承载PEI PDCCH的CSS set(所述用于承载PEI PDCCH的CSS set属于所述第一SS set)的候选PDCCH的分配，即在设置第二SS set的情况下，可选地，第二SS set包括用于承载PEI PDCCH的CSS set；和/或，所述用于承载PEI PDCCH的CSS set的映射优先级高于以下至少一项：除所述用于承载PEI PDCCH的CSS set之外的CSS set的映射优先级、USS set的映射优先级。Optionally, it may be determined whether to allow the terminal in the disconnected state to abandon the CSS set used to carry the PEI PDCCH according to whether the terminal in the disconnected state performs paging PDCCH monitoring when the terminal in the disconnected state does not detect the PEI. Allocation of candidate PDCCHs, and/or mapping priorities for CSS sets carrying PEI PDCCHs. For example, in a possible implementation manner, when the network configuration or protocol stipulates that the terminal in the disconnected state does not perform paging PDCCH monitoring when no PEI is detected, the terminal in the disconnected state is not allowed to The terminal abandons the allocation of the candidate PDCCH for the CSS set used to carry the PEI PDCCH (the CSS set used to carry the PEI PDCCH belongs to the first SS set), that is, when the second SS set is set, optionally , the second SS set includes a CSS set for carrying PEI PDCCH; and/or, the mapping priority of the CSS set for carrying PEI PDCCH is higher than at least one of the following: except for the CSS set for carrying PEI PDCCH The mapping priority of CSS sets other than the set, and the mapping priority of USS sets.
例如，网络侧设备广播当前小区中，如果UE没有检测到唤醒自己的PEI则不进行寻呼PDCCH监听，为了保证UE能够检测到其PEI，避免寻呼PDCCH被漏检，可以设置不允许所述处于非连接态的终端放弃对用于承载PEI PDCCH的CSS set的候选PDCCH的分配，和/或，将所述用于承载PEI PDCCH的CSS set的映射优先级设置为高于以下至少一项：除所述用于承载PEI PDCCH的CSS set之外的CSS set的映射优先级、USS set的映射优先级。 处于非连接态的终端在对当前第一时间单元内的候选PDCCH进行分配时，先分配用于承载PEI PDCCH的CSS set(可以称之为PEI CSS set)，再分配以下至少一项：除所述用于承载PEI PDCCH的CSS set之外的CSS set、USS set。For example, in the current cell broadcast by the network side device, if the UE does not detect the PEI that wakes up itself, it will not monitor the paging PDCCH. The terminal in the disconnected state abandons the allocation of the candidate PDCCH for the CSS set bearing the PEI PDCCH, and/or sets the mapping priority of the CSS set for bearing the PEI PDCCH to be higher than at least one of the following: The mapping priority of the CSS set and the mapping priority of the USS set other than the CSS set used to carry the PEI PDCCH. When the terminal in the disconnected state allocates the candidate PDCCH in the current first time unit, it first allocates the CSS set (which may be called the PEI CSS set) for carrying the PEI PDCCH, and then allocates at least one of the following: Describe the CSS set and USS set other than the CSS set used to carry the PEI PDCCH.
在另一个可能的实现方式中，在网络配置或协议约定所述处于非连接态的终端在没有检测到PEI时，进行寻呼PDCCH监听的情况下，允许所述处于非连接态的终端放弃对用于承载PEI PDCCH的CSS set的候选PDCCH的分配，即在设置第三SS set的情况下，可选地，第三SS set包括用于承载PEI PDCCH的CSS set；和/或，所述用于承载PEI PDCCH的CSS set的映射优先级低于以下至少一项：除所述用于承载PEI PDCCH的CSS set之外的CSS set的映射优先级、USS set的映射优先级。In another possible implementation manner, when the network configuration or protocol stipulates that the terminal in the disconnected state performs paging PDCCH monitoring when no PEI is detected, the terminal in the disconnected state is allowed to give up the pairing Allocation of candidate PDCCHs for the CSS set bearing the PEI PDCCH, that is, in the case of setting the third SS set, optionally, the third SS set includes the CSS set for bearing the PEI PDCCH; and/or, the use of the The mapping priority of the CSS set bearing the PEI PDCCH is lower than at least one of the following: the mapping priority of the CSS set other than the CSS set used to bear the PEI PDCCH, and the mapping priority of the USS set.
例如，网络侧设备广播当前小区采用UE检测PEI的相关行为为：UE没有检测到唤醒自己的PEI则进行寻呼PDCCH监听。由于UE即使未检测到唤醒自己的PEI，也进行寻呼PDCCH的监听，因此，即使用于承载PEI PDCCH的CSS set的PDCCH的被放弃分配，也不会影响UE监听寻呼PDCCH，因此，可以允许所述处于非连接态的终端放弃对用于承载PEI PDCCH的CSS set的候选PDCCH的分配和/或用于承载PEI PDCCH的CSS set的映射优先级设置为较低。例如，协议可以约定允许PEI CSS set可以因超过最大相关处理能力(即，最大BD或者CCE个数限制)而被放弃分配，且PEI CSS set的映射优先级小于USS set的映射优先级。则UE在进行当前slot内的PDCCH candidate分配时，RRC Inactive UE先分配除PEI CSS之外的CSS set，再分配USS集合，接下来分配PEI CSS，但UE判断发现如果分配了PEI CSS则会超过最大不重叠CCE个数的能力限制，则UE将当前slot内的PEI CSS set丢弃，也就是放弃对该PEI CSS set的候选PDCCH的分配。For example, the relevant behavior of the network side device broadcasting the current cell using the UE to detect the PEI is: the UE performs paging and PDCCH monitoring without detecting the PEI that wakes up itself. Since the UE monitors the paging PDCCH even if it does not detect the PEI that wakes it up, even if the PDCCH for the CSS set carrying the PEI PDCCH is abandoned, it will not affect the UE's monitoring of the paging PDCCH. Therefore, it is possible to The terminal in the disconnected state is allowed to give up the allocation of candidate PDCCHs for the CSS set bearing PEI PDCCH and/or the mapping priority of the CSS set bearing PEI PDCCH is set to be lower. For example, the protocol may agree to allow PEI CSS sets to be abandoned due to exceeding the maximum relevant processing capability (ie, the maximum number of BDs or CCEs), and the mapping priority of the PEI CSS set is smaller than that of the USS set. When the UE allocates the PDCCH candidate in the current slot, the RRC Inactive UE first allocates the CSS set except the PEI CSS, then allocates the USS set, and then allocates the PEI CSS, but the UE judges that if the PEI CSS is allocated, it will exceed If the maximum number of non-overlapping CCEs is limited, the UE discards the PEI CSS set in the current slot, that is, abandons the allocation of the candidate PDCCH for the PEI CSS set.
在一个可能的实现方式中，所述用于承载PEI PDCCH的CSS set的映射优先级最低。例如，网络侧设备配置或协议约定用于承载PEI PDCCH的CSS  set的映射优先级最低，例如，如果终端在分配PEI CSSset前发现如果再分配PEI CSS set则会超过最大BD或者CCE个数限制，则丢弃该PEI CSSset。In a possible implementation manner, the mapping priority of the CSS set for carrying the PEI PDCCH is the lowest. For example, the network-side device configuration or protocol stipulates that the CSS set used to carry the PEI PDCCH has the lowest mapping priority. The PEI CSSset is then discarded.
在一个可能的实现方式中，所述第一SS set的映射优先级从高到低的顺序还包括以下(1)至(4)中的至少一项。In a possible implementation manner, the order of mapping priorities of the first SS set from high to low further includes at least one of the following (1) to (4).
(1)除所述用于承载PEI PDCCH的CSS set之外的CSS set、所述第一USS set、所述用于承载PEI PDCCH的CSS set。(1) CSS sets other than the CSS set used to carry the PEI PDCCH, the first USS set, and the CSS set used to carry the PEI PDCCH.
例如，所述处于非连接态的终端在分配第一时间单元内第一SS set的候选PDCCH时，先分配除PEI CSS set之外的CSS set；再分配USS集合；最后分配PEI CSS set。如果UE判断超过了自身的最大BD或最大不重叠CCE个数限制，则按照此优先级依次丢弃。例如，PEI CSS set优先级小于SDT USS set，当UE在分配完SDT USS set时发现如果再分配PEI CSS set则会超过最大BD or CCE个数限制，则丢弃PEI CSS set。For example, when the terminal in the disconnected state allocates the candidate PDCCH of the first SS set in the first time unit, first allocates the CSS set except the PEI CSS set; then allocates the USS set; and finally allocates the PEI CSS set. If the UE determines that it exceeds its own maximum BD or the maximum number of non-overlapping CCEs, it will be discarded in sequence according to this priority. For example, the PEI CSS set has a lower priority than the SDT USS set. When the UE finds that the PEI CSS set will exceed the maximum number of BDs or CCEs if the SDT USS set is allocated, the PEI CSS set will be discarded.
其中，该映射优先级顺序可以是第一规则指示的，例如，网络侧设备配置的或协议约定的。Wherein, the mapping priority order may be indicated by the first rule, for example, configured by the network side device or stipulated by the protocol.
(2)除所述用于承载PEI PDCCH的CSS set之外的CSS set、所述用于承载PEI PDCCH的CSS set、所述第一USS set。(2) CSS sets other than the CSS set used to carry PEI PDCCH, the CSS set used to carry PEI PDCCH, and the first USS set.
例如，所述处于非连接态的终端在分配第一时间单元内第一SS set的候选PDCCH时，先分配除所述用于承载PEI PDCCH的CSS set之外的CSS set，再分配用于承载PEI PDCCH的CSS set，最后分配所述第一USS set。如果UE判断超过了自身的最大BD或最大不重叠CCE个数限制，则按照此优先级依次丢弃。例如，SDT USS set的映射优先级小于PEI CSS set，当UE在分配完PEI CSS set时发现如果再分配SDT USS set则会超过最大BD或者CCE个数限制，则丢弃SDT USS set。For example, when allocating the candidate PDCCH of the first SS set in the first time unit, the terminal in the disconnected state first allocates the CSS set other than the CSS set used to carry the PEI PDCCH, and then allocates the CSS set used to carry the PEI PDCCH. The CSS set of the PEI PDCCH, and finally the first USS set is allocated. If the UE determines that it exceeds its own maximum BD or the maximum number of non-overlapping CCEs, it will be discarded in sequence according to this priority. For example, the mapping priority of the SDT USS set is lower than that of the PEI CSS set. When the UE finds that the maximum number of BDs or CCEs will be exceeded if the SDT USS set is re-allocated after allocating the PEI CSS set, the SDT USS set is discarded.
其中，该映射优先级顺序可以是第一规则指示的，例如，网络侧设备配置的或协议约定的。Wherein, the mapping priority order may be indicated by the first rule, for example, configured by the network side device or stipulated by the protocol.
(3)所述第一CSS set、所述第一USS set。(3) The first CSS set and the first USS set.
(4)所述第一USS set、所述第一CSS set。(4) The first USS set and the first CSS set.
在一个可能的实现方式中，网络侧设备可以广播所述第一CSS set相对于所述第一USS set的映射优先级，并预先可以配置或约定上述(1)和(2)的优先级，处于非连接态的终端根据网络侧设备的广播的内容，确定是采用上述(1)还是(2)的映射优先级顺序。例如，如果网络侧设备广播所述第一CSS set的映射优先级高于所述第一USS set的映射优先级，则处于非连接态的终端可以确定采用上述(2)的映射优先级顺序。或者，网络侧设备也可以广播全部的SS set的映射优先级顺序，例如，广播上述(1)或(2)所述的优先级顺序。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 on the priorities of the above (1) and (2) in advance, The terminal in the disconnected state determines whether to adopt the mapping priority order of the above (1) or (2) according to the broadcast content of the network side device. For example, if the network-side device broadcasts the mapping priority of the first CSS set higher than the mapping priority of the first USS set, the terminal in the disconnected state can determine to adopt the mapping priority order of the above (2). Alternatively, the network-side device may also broadcast the mapping priority order of all SS sets, for example, broadcast the priority order described in (1) or (2) above.
或者，处于非连接态的终端也可以自行判定所述第一CSS set相对于所述第一USS set的映射优先级，从而确定是采用上述(1)还是(2)的映射优先级顺序。例如，在网络侧设备配置或协议约定所述处于非连接态的终端在没有检测到PEI时，进行寻呼PDCCH监听的情况下，则处于非连接态的终端可以确定采用上述(1)的映射优先级顺序。在网络侧设备配置或协议约定所述处于非连接态的终端在没有检测到PEI时，不进行寻呼PDCCH监听的情况下则处于非连接态的终端可以确定采用上述(2)的映射优先级顺序。Alternatively, the terminal in the disconnected state can also 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 the case that the terminal in the disconnected state performs paging PDCCH monitoring when the terminal in the disconnected state does not detect the PEI according to the device configuration or the protocol on the network side, the terminal in the disconnected state can determine to use the mapping of (1) above. priority order. In the device configuration or protocol on the network side, when the terminal in the disconnected state does not detect PEI and does not monitor the paging PDCCH, the terminal in the disconnected state can determine to use the mapping priority of (2) above. order.
在一个可能的实现方式中，第四SS set的映射优先级由网络配置或协议约定，其中，所述第一SS set中包括所述第四SS set。例如，第四SS set可以包括所述用于承载PEI PDCCH的CSS set。此外，网络侧设备可以通过广播SIB消息通知给所述处于非连接态的终端，所述用于承载PEI PDCCH的CSS set的映射优先级。In a possible implementation manner, the mapping priority of the fourth SS set is stipulated by network configuration or protocol, wherein the first SS set includes the fourth SS set. For example, the fourth SS set may include the CSS set for carrying the PEI PDCCH. In addition, the network side device can notify the terminal in the disconnected state by broadcasting the SIB message, the mapping priority of the CSS set used to bear the PEI PDCCH.
在一个可能的实现方式中，所述处于非连接态的终端根据第一规则，分配第一时间单元内第一搜索空间集合SS set的候选PDCCH，包括：In a possible implementation manner, the terminal in the disconnected state allocates candidate PDCCHs of the first search space set SSset in the first time unit according to the first rule, including:
所述处于非连接态的终端按照所述第一SS set的映射优先级从高到低的顺序，依次分配所述第一SS set的候选PDCCH；The terminal in the disconnected state sequentially allocates the candidate PDCCHs of the first SS set according to the order of the mapping priorities of the first SS set from high to low;
其中，在分配目标SS set的候选PDCCH之前，如果确定分配所述目标 SS set的候选PDCCH将会导致超过所述处于非连接态的终端的最大处理能力，则放弃分配所述目标SS set以及第五SS set的候选PDCCH；其中，所述第五SS set的映射优先级低于所述目标SS set的映射优先级，所述第一SS set包括所述目标SS set和所述第五SS set。Wherein, before allocating the candidate PDCCH of the target SS set, if it is determined that the allocation of the candidate PDCCH of the target SS set will result in exceeding the maximum processing capability of the terminal in the non-connected state, the allocation of the target SS set and the first Candidate PDCCH of five SS sets; 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 includes the target SS set and the fifth SS set .
例如，SDT USS set的映射优先级小于PEI CSS set，当UE在分配完PEI CSS set时发现如果再分配SDT USS set则会超过最大BD或者CCE个数限制，则丢弃SDT USS set。For example, the mapping priority of the SDT USS set is lower than that of the PEI CSS set. When the UE finds that the maximum number of BDs or CCEs will be exceeded if the SDT USS set is re-allocated after allocating the PEI CSS set, the SDT USS set is discarded.
可选地，所述处于非连接态的终端的最大处理能力包括：支持的第一时间单元内的最大候选PDCCH数；和/或，支持的第一时间单元内的最大不重叠的控制信道元素(CCE)数。Optionally, the maximum processing capability of the terminal in the disconnected state includes: the maximum number of candidate PDCCHs in the supported first time unit; and/or the maximum non-overlapping control channel elements in the supported first time unit (CCE) number.
在具体应用中，终端对承载有DCI的候选PDCCH(PDCCH candidates)的解调过程可以是：终端找到CCE的起始位置，在CCE起始位置，尝试不同的聚合等级，截取猜测的DCI长度，进行译码，对于不同的期望信息终端使用相应的无线网络临时标识(Radio Network Temporary Identifier，RNTI)与CCE信息做循环冗余校验(Cyclic redundancy check，CRC)，如果CRC校验成功，则终端确定这个信息是自己需要的，该过程称之为盲检过程。在这个过程中，终端的尝试译码DCI的次数为盲检次数。PDCCH candidates的每个CCE位置，都可以通过预设方式计算得出。某个PDCCH信道的所有PDCCH candidates的起始CCE位置，与该PDCCH信道的聚合等级、搜索空间类型、子帧号、可用CCE总个数、RNTI等参数有关。In a specific application, the terminal's demodulation process for candidate PDCCH (PDCCH candidates) carrying DCI may be: the terminal finds the starting position of the CCE, tries different aggregation levels at the starting position of the CCE, and intercepts the guessed DCI length, Decoding, for different expected information terminals, use the corresponding wireless network temporary identifier (Radio Network Temporary Identifier, RNTI) and CCE information to do cyclic redundancy check (Cyclic redundancy check, CRC), if the CRC check is successful, then the terminal Determining that this information is what you need is called a blind detection process. In this process, the number of times the terminal attempts to decode the DCI is the number of blind detections. Each CCE position of PDCCH candidates can be calculated by default. The starting CCE position of all PDCCH candidates of a certain PDCCH channel is related to the aggregation level, search space type, subframe number, total number of available CCEs, RNTI and other parameters of the PDCCH channel.
通过本申请实施例提供的上述方法，处于非连接态的终端可以按照第一规则，分配第一时间单元内第一SS set的候选PDCCH，从而明确处于非连接态的终端对候选PDCCH的分配过程，避免了超出处于非连接态的终端最大相关处理能力等问题，提高了调度传输的性能。Through the above method provided in the embodiment of the present application, the terminal in the disconnected state can allocate the candidate PDCCH of the first SS set in the first time unit according to the first rule, so as to clarify the allocation process of the candidate PDCCH by the terminal in the disconnected state , which avoids the problem of exceeding the maximum related processing capability of the terminal in the disconnected state, and improves the performance of scheduling transmission.

In other words, the method can be executed by software or hardware installed on the terminal, as shown in FIG. 3 , the method 300 can include the following steps.
S310，在终端不需要监听PEI的情况下，所述终端确定寻呼PDCCH的监听行为。其中，所述寻呼PDCCH的监听行为包括以下任一项：进行寻呼PDCCH的监听；不进行寻呼PDCCH的监听。S310, in the case that the terminal does not need to monitor the PEI, the terminal determines the monitoring behavior of the paging PDCCH. The monitoring behavior of the paging PDCCH includes any one of the following: monitoring the paging PDCCH; and not monitoring the paging PDCCH.
在本申请实施例中，终端可以是处于连接态的终端，例如，RRC connectedUE，或者，也可以是处于非连接态的终端，例如，RRC idle UE，或者RRC inactive UE。具体本申请实施例中不作限定。In this embodiment of the present application, the terminal may be a terminal in a connected state, for example, an RRC connected UE, or may also be a terminal in a disconnected state, for example, an RRC idle UE, or an RRC inactive UE. There is no specific limitation in the embodiments of the present application.
在本申请实施例提供的技术方案中，终端可以在不需要监听PEI的情况下，确定寻呼PDCCH的监听行为，并执行该监听行为。In the technical solutions provided by the embodiments of the present application, the terminal may determine the monitoring behavior of the paging PDCCH without monitoring the PEI, and execute the monitoring behavior.
在一个可能的实现方式中，所述终端确定寻呼PDCCH的监听行为，包括：根据网络侧设备的配置，确定所述终端监听或不监听寻呼PDCCH。In a possible implementation manner, the terminal determining the monitoring behavior of the paging PDCCH includes: according to the configuration of the network side device, determining whether the terminal monitors or does not monitor the paging PDCCH.
或者，终端也可以确定在不需要监听PEI的情况下，寻呼PDCCH的监听行为，例如，网络侧设备配置或协议约定UE没有检测到唤醒自己的PEI则进行寻呼PDCCH监听，则终端在不需要监听PEI的情况下，进行寻呼PDCCH监听。而在网络侧设备配置或协议约定所述处于非连接态的终端在没有检测到PEI时，进行寻呼PDCCH监听的情况下，在终端在不需要监听PEI的情况下，不进行寻呼PDCCH监听。Alternatively, the terminal can also determine the monitoring behavior of paging the PDCCH without monitoring the PEI. For example, the network side device configuration or the protocol stipulates that the UE will perform paging PDCCH monitoring without detecting the PEI that wakes up itself. When the PEI needs to be monitored, the paging PDCCH monitoring is performed. However, in the case that the terminal in the disconnected state performs paging PDCCH monitoring when the terminal in the disconnected state does not detect PEI in the device configuration or protocol on the network side, if the terminal does not need to monitor PEI, it does not perform paging PDCCH monitoring. .
在一个可能的实现方式中，在以下至少一项的情况下，所述终端不需要监听PEI：In a possible implementation manner, in the case of at least one of the following, the terminal does not need to monitor PEI:
(1)所述终端未进行用于承载PEI PDCCH的CSS set的候选PDCCH的分配；(1) The terminal does not allocate a candidate PDCCH for the CSS set bearing the PEI PDCCH;
(2)PEI所在时间单元的传输方向被修改；(2) The transmission direction of the time unit where the PEI is located is modified;
(3)PEI与其他信道或信号发生冲突或重叠。例如，PEI与其他传输冲突或与其他传输重叠(overlap)，该其他传输比PEI检测的优先级更高。其中，其他传输包括但不限于：接收、检测、测量或发送中至少一项。(3) PEI collides or overlaps with other channels or signals. For example, PEI collides with or overlaps with other transmissions that have a higher priority than PEI detection. Wherein, other transmissions include, but are not limited to, at least one of receiving, detecting, measuring, or sending.

其中，第一规则与方法200中的第一规则相同，也就是说，方法400是与方法200中，第一规则由网络侧设备配置对应的网络侧设备的方法。Wherein, the first rule is the same as the first rule in method 200, that is, method 400 is the same as in method 200, in which the network side device configures the corresponding network side device for the first rule.
其中，配置信息可以是方法200中由网络侧设备配置的各个可能的信息，具体可以参见方法200中的相关描述。The configuration information may be all possible information configured by the network-side device in the method 200 , for details, please refer to the relevant description in the method 200 .
在本申请实施例中，第一SSset包括但不限于第一公共搜索空间集合(CSS set)和第一专用搜索空间集合(USS set)中至少一项。In this embodiment of the present application, 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).
可选地，第一CSS set可以包括以下(1)至(8)中的至少一项。Optionally, the first CSS set may include at least one of the following (1) to (8).

可选地，所述第一USS set包括但不限于用于承载SDT PDCCH的USS集合。Optionally, the first USS set includes but is not limited to the USS set used to carry the SDT PDCCH.
在一个可能的实现方式中，所述第一规则还用于指示以下(1)至(2)中的至少一项。In a possible implementation manner, the first rule is further used to indicate at least one of the following (1) to (2).
(1)不允许所述处于非连接态的终端放弃对第二SS set的候选PDCCH的分配。(1) The terminal in the disconnected state is not allowed to give up the allocation of the candidate PDCCH of the second SS set.
例如，为了保证第二SS set不会因为超过最大处理能力而被终端丢弃分配，网络侧设备可以配置不允许所述处于非连接态的终端放弃对第二SS set的候选PDCCH的分配。也就是说，所述处于非连接态的终端在第一时间单元内必须进行第二SSset的候选PDCCH的分配。For example, in order to ensure that the second SS set will not be discarded and allocated by the terminal because it exceeds the maximum processing capacity, the network side device may be configured to not allow the terminal in the disconnected state to give up the allocation of the candidate PDCCH for the second SS set. That is to say, the terminal in the disconnected state must allocate the candidate PDCCH of the second SSset within the first time unit.
例如，第二SS set可以是包含以下至少一项：用于承载PEI PDCCH的CSSset、用于承载SDT PDCCH的CSS set。或者，第二SS set可以是除用于承载PEI PDCCH的CSS set之外的CSS set。For example, the second SS set may include at least one of the following: a CSS set for carrying PEI PDCCH and a 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)允许所述处于非连接态的终端放弃对第三SS set的候选PDCCH的分配。(2) Allow the terminal in the disconnected state to abandon the allocation of the candidate PDCCH of the third SS set.
例如，网络侧设备可以配置定允许第三CSS set可以被idle/inactive态终端放弃分配。For example, the network-side device may be configured to allow the third CSS set to be abandoned by the idle/inactive terminal.
其中，所述第一SSset中包括所述第二SSset和所述第三SSset。Wherein, the first SSset includes the second SSset and the third SSset.
在一种实施例中，所述第三SS set可以包括以下至少一项：In one embodiment, the third SS set may include at least one of the following:
(a)用于承载PEI PDCCH的CSS set；(a) CSS set for carrying PEI PDCCH;
(b)用于承载MBS PDCCH的CSS set；(b) CSS set for carrying MBS PDCCH;
(c)用于承载SDT PDCCH的CSS set；(c) CSS set for carrying SDT PDCCH;
(d)第一USS set。(d) First USS set.
在上述可能的实现方式中，一个SS set只能是第二SS set或第三SS set中的一项，不能同时属于第二SS set和第三SS set。In the above possible implementation manners, an SS set can only be one of the second SS set or the third SS set, and cannot belong to the second SS set and the third SS set at the same time.
通过上述第一规则的指示，处于非连接态的终端可以根据不允许所述处于非连接态的终端放弃对第二SS set的候选PDCCH的分配和/或允许所述处于非连接态的终端放弃对第三SS set的候选PDCCH的分配，确定第二SS set和/或第三SS set的映射优先级。According to the indication of the first rule, the terminal in the disconnected state may not allow the terminal in the disconnected state to give up the allocation of the candidate PDCCH of the second SS set and/or allow the terminal in the disconnected state to give up For the allocation of candidate PDCCHs of the third SS set, the mapping priorities of the second SS set and/or the third SS set are determined.
在一个可能的实现方式中，在第一规则还用于指示不允许所述处于非连 接态的终端放弃对第二SS set的候选PDCCH的分配和/或允许所述处于非连接态的终端放弃对第三SS set的候选PDCCH的分配的情况下，指示所述第一SS set的映射优先级从高到低的顺序包括以下(1)至(3)中任一项。In a possible implementation manner, the first rule is further used to indicate that the terminal in the disconnected state is not allowed to give up the allocation of the candidate PDCCH of the second SS set and/or the terminal in the disconnected state is allowed to give up In the case of allocation of candidate PDCCHs for the third SS set, the order indicating the mapping priority of the first SS set from high to low includes any of the following (1) to (3).
(1)所述第二SS set、除所述第二SS set之外的SS set。(1) The second SS set, SS sets other than the second SS set.
例如，在第一规则指示不允许所述处于非连接态的终端放弃对第二SS set的候选PDCCH的分配的情况下，为了保证第二SS set的候选PDCCH的分配，将所述第二SS set的映射优先级设置为高优先级，所述处于非连接态的终端优先分配第二SS set的候选PDCCH。For example, when the first rule indicates that the terminal in the disconnected state is not allowed to give up the allocation of the candidate PDCCH of the second SS set, in order to ensure the allocation of the candidate PDCCH of the second SS set, the second SS The mapping priority of the set is set to a high priority, and the terminal in the non-connected state is preferentially allocated the candidate PDCCH of the second SS set.
(2)除所述第三SS set之外的SS set、所述第三SS set。(2) SS sets other than the third SS set, the third SS set.
例如，在第一规则指示允许所述处于非连接态的终端放弃对第三SSset的候选PDCCH的分配的情况下，由于第三SSset的候选PDCCH可以被放弃分配，因此，可以将所述第三SS set的映射优先级设置为最低优先级，即先分配除第三SSset之外的SSset的候选PDCCH，然后再分配第三SSset的候选PDCCH。For example, if the first rule indicates that the terminal in the disconnected state is allowed to give up the allocation of the candidate PDCCH of the third SSset, since the allocation of the candidate PDCCH of the third SSset can be abandoned, the third SSset can be given up. The mapping priority of the SS set is set to the lowest priority, that is, the candidate PDCCHs of the SSsets other than the third SSset are allocated first, and then the candidate PDCCHs of the third SSset are allocated.
(3)所述第二SS set、所述第三SS set。(3) The second SS set and the third SS set.
例如，在第一规则指示不允许所述处于非连接态的终端放弃对第二SS set的候选PDCCH的分配、且允许所述处于非连接态的终端放弃对第三SSset的候选PDCCH的分配的情况下，可以将第二SS set的映射优先级设置为高于第三SS set的优先级。For example, when the first rule indicates that the terminal in the disconnected state is not allowed to give up the allocation of the candidate PDCCH of the second SSset, and the terminal in the disconnected state is allowed to give up the allocation of the candidate PDCCH of the third SSset In this case, the mapping priority of the second SS set may be set higher than the priority of the third SS set.
在上述可能的实现方式中，第一规则可以通过指示不允许所述处于非连接态的终端放弃对第二SS set的候选PDCCH的分配和/或允许所述处于非连接态的终端放弃对第三SS set的候选PDCCH的分配，隐式的指示第二SS set和/或第三SS set的优先级。In the above possible implementation manner, the first rule may indicate that the terminal in the disconnected state is not allowed to give up the allocation of the candidate PDCCH of the second SS set and/or allow the terminal in the disconnected state to give up the assignment to the second SS set. The allocation of candidate PDCCHs for the three SS sets implicitly indicates the priority of the second SS set and/or the third SS set.
在一个可能的实现方式中，所述配置信息还可以指示所述处于非连接态的终端在没有检测到PEI时，是否进行寻呼PDCCH监听。在一个可能的实现方式中，还可以根据所述配置信息指示在所述处于非连接态的终端在没有 检测到PEI时，是否进行寻呼PDCCH监听来确定是否允许所述处于非连接态的终端放弃对用于承载PEI PDCCH的CSS set的候选PDCCH的分配，和/或用于承载PEI PDCCH的CSS set的映射优先级。In a possible implementation manner, the configuration information may further indicate whether the terminal in the disconnected state performs paging PDCCH monitoring when no PEI is detected. In a possible implementation manner, whether to perform paging PDCCH monitoring when the terminal in the disconnected state does not detect PEI may also be indicated according to the configuration information to determine whether to allow the terminal in the disconnected state Abandon the allocation of candidate PDCCHs for the CSS set carrying the PEI PDCCH, and/or the mapping priority for the CSS set carrying the PEI PDCCH.
可选地，在所述配置信息还指示所述处于非连接态的终端在没有检测到PEI时，不进行寻呼PDCCH监听的情况下，不允许所述处于非连接态的终端放弃对用于承载PEI PDCCH的CSS set的候选PDCCH的分配；和/或，所述用于承载PEI PDCCH的CSS set的映射优先级高于以下至少一项：除所述用于承载PEI PDCCH的CSS set之外的CSS set的映射优先级、USS set的映射优先级。Optionally, when the configuration information further indicates that the terminal in the disconnected state does not perform paging PDCCH monitoring when no PEI is detected, the terminal in the disconnected state is not allowed to give up the Allocation of candidate PDCCHs of the CSS set bearing PEI PDCCH; and/or, the mapping priority of the CSS set used to carry the PEI PDCCH is higher than at least one of the following: in addition to the CSS set used to carry the PEI PDCCH The mapping priority of the CSS set and the mapping priority of the USS set.
在另一个可能的实现方式中，在所述配置信息还指示所述处于非连接态的终端在没有检测到PEI时，进行寻呼PDCCH监听的情况下，允许所述处于非连接态的终端放弃对用于承载PEI PDCCH的CSS set的候选PDCCH的分配；和/或所述用于承载PEI PDCCH的CSS set的映射优先级低于以下至少一项：除所述用于承载PEI PDCCH的CSS set之外的CSS set的映射优先级、USS set的映射优先级。In another possible implementation manner, when the configuration information further indicates that the terminal in the disconnected state performs paging PDCCH monitoring when no PEI is detected, the terminal in the disconnected state is allowed to give up allocation of candidate PDCCHs for the CSS set for carrying PEI PDCCH; and/or the mapping priority of the CSS set for carrying PEI PDCCH is lower than at least one of the following: except for the CSS set for carrying PEI PDCCH The mapping priority of the CSS set other than the mapping priority of the USS set.
在一个可能的实现方式中，所述配置信息指示所述第一SS set的映射优先级从高到低的顺序包括以下(1)至(4)中至少一项。In a possible implementation manner, the configuration information indicates that the order of mapping priorities of the first SS set from high to low includes at least one of the following (1) to (4).
(1)除用于承载PEI PDCCH的CSS set之外的CSS set、第一USS set、用于承载PEI PDCCH的CSS set。(1) CSS sets other than the CSS set used to carry the PEI PDCCH, the first USS set, and the CSS set used to carry the PEI PDCCH.
其中，如上所述，所述第一SS set中可以包括第一CSS set和所述第一USS set中的至少一项，所述第一CSS set包括所述用于承载PEI PDCCH的CSS set。Wherein, as described above, the first SS set may include at least one of the first CSS set and the first USS set, and the first CSS set includes the CSS set for carrying the PEI PDCCH.
此外，第一CSS set还可以包括以下至少一项：Additionally, the first CSS set may also include at least one of the following:
(a)用于承载多播广播业务(Multicast/Broadcast Service，MBS)PDCCH的CSS set；(a) CSS set used to carry the Multicast/Broadcast Service (MBS) PDCCH;
(b)用于承载小数据传输(Small Data Transmission，SDT)PDCCH的 CSS set；(b) CSS set for carrying Small Data Transmission (SDT) PDCCH;
(c)类型0PDCCH(Type0-PDCCH)CSS set；(c) Type 0 PDCCH (Type0-PDCCH) CSS set;
(d)类型0A PDCCH(Type0A-PDCCH)CSS set；(d) Type 0A PDCCH (Type0A-PDCCH) CSS set;
(e)类型1 PDCCH(Type1-PDCCH)CSS set；(e) Type 1 PDCCH (Type1-PDCCH) CSS set;
(f)类型2 PDCCH(Type2-PDCCH)CSS set；(f) Type 2 PDCCH (Type2-PDCCH) CSS set;
(g)类型3 PDCCH(Type3-PDCCH)CSS set。(g) Type 3 PDCCH (Type3-PDCCH) CSS set.
所述第一USS set包括但不限于用于承载SDT PDCCH的USS集合。The first USS set includes but is not limited to the USS set used to carry the SDT PDCCH.
(2)除用于承载PEI PDCCH的CSS set之外的CSS set、用于承载PEI PDCCH的CSS set、第一USS set。(2) CSS sets other than the CSS set used to carry the PEI PDCCH, the CSS set used to carry the PEI PDCCH, and the first USS set.
(3)第一CSS set、第一USS set。(3) The first CSS set, the first USS set.
(4)第一USS set、第一CSS set。(4) The first USS set, the first CSS set.
在一个可能的实现方式中，网络侧设备可以配置所述第一CSS set相对于所述第一USS set的映射优先级(即上述(3)或(4))，并预先可以配置或约定上述(1)和(2)的优先级，处于非连接态的终端根据网络侧设备的广播的内容，确定是采用上述(1)还是(2)的映射优先级顺序。例如，如果网络侧设备广播所述第一CSS set的映射优先级高于所述第一USS set的映射优先级，则处于非连接态的终端可以确定采用上述(2)的映射优先级顺序。或者，网络侧设备也可以广播全部的SS set的映射优先级顺序，例如，广播上述(1)或(2)所述的优先级顺序。In a possible implementation manner, the network side device may configure the mapping priority of the first CSS set relative to the first USS set (that is, the above (3) or (4)), and may configure or agree on the above For the priorities of (1) and (2), the terminal in the disconnected state determines whether to adopt the mapping priority order of (1) or (2) according to the broadcast content of the network side device. For example, if the network-side device broadcasts the mapping priority of the first CSS set higher than the mapping priority of the first USS set, the terminal in the disconnected state can determine to adopt the mapping priority order of the above (2). Alternatively, the network-side device may also broadcast the mapping priority order of all SS sets, for example, broadcast the priority order described in (1) or (2) above.
在一个可能的实现方式中，所述第一规则指示用于承载PEI PDCCH的CSS set的映射优先级最低。即网络侧设备配置所述用于承载PEI PDCCH的CSS set的映射优先级最低。例如，在网络侧设备配置或协议约定所述处于非连接态的终端在没有检测到PEI时，进行寻呼PDCCH监听，网络侧设备可以配置第一规则指示用于承载PEI PDCCH的CSS set的映射优先级最低。In a possible implementation manner, the first rule indicates that the CSS set used to carry the PEI PDCCH has the lowest mapping priority. That is, the network side device configures the CSS set for carrying the PEI PDCCH with the lowest mapping priority. For example, in the configuration of the network side device or the agreement in the protocol, when the terminal in the disconnected state does not detect the PEI, it performs paging PDCCH monitoring, and the network side device can configure the first rule to indicate the mapping of the CSS set used to carry the PEI PDCCH lowest priority.
在一个可能的实现方式中，所述第一规则指示第四SS set的映射优先级，其中，所述第一SS set中包括所述第四SS set。例如，第四SS set可以包括 所述用于承载PEI PDCCH的CSS set。此外，网络侧设备可以通过广播SIB消息为所述处于非连接态的终端配置，所述用于承载PEI PDCCH的CSS set的映射优先级。In a possible implementation manner, the first rule indicates a mapping priority of a fourth SS set, wherein the first SS set includes the fourth SS set. For example, the fourth SS set may include the CSS set for carrying the PEI PDCCH. In addition, the network side device can configure the mapping priority of the CSS set for carrying the PEI PDCCH for the terminal in the disconnected state by broadcasting the SIB message.
通过本申请实施例提供的上述方法，网络侧设备可以为处于非连接态的终端配置搜索空间集合分配的第一规则，从而使得处于非连接态的终端可以按照第一规则分配第一时间单元的第一SS set，从而明确处于非连接态的终端对候选PDCCH的分配过程，避免了超出处于非连接态的终端最大相关处理能力等问题，提高了调度传输的性能。Through the above method provided in the embodiment of the present application, the network side device can configure the first rule of search space set allocation for the terminal in the disconnected state, so that the terminal in the disconnected state can allocate the first time unit according to the first rule. The first SS set, thereby clarifying the allocation process of the terminal in the disconnected state to the candidate PDCCH, avoids problems such as exceeding the maximum related processing capability of the terminal in the disconnected state, and improves the performance of scheduling transmission.
