The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The term "plurality" in the embodiments of the present disclosure means two or more, and other terms are similar thereto.
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only some embodiments of the present disclosure, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The embodiment of the disclosure provides a resource determination method, a resource determination device, a network device, a terminal device and a storage medium, which are used for determining a target transmission resource occupied by control information sent by the network device in a process of switching between single transmission and repeated transmission so that the terminal device can receive the control information sent by the network device.
Fig. 1 is a schematic flowchart of a resource determining method provided in an embodiment of the present application, where the method is used for a terminal device, and as shown in fig. 1, the method includes the following steps:
step 101, receiving a target signaling sent by a network device, wherein the target signaling is used for notifying switching between single transmission and repeated transmission of a PDCCH.
And under the condition that the network equipment performs dynamic switching between single transmission and repeated transmission, sending a target signaling to the terminal equipment, wherein the target signaling is used for informing the terminal equipment of the dynamic switching between the single transmission and the repeated transmission. In some scenarios, it is the network device that notifies the terminal device to switch from a single transmission to a repeated transmission, in other scenarios, it may be the network device that notifies the terminal device to switch from a repeated transmission to a single transmission, in other scenarios, it may be the network device that notifies the terminal device to switch from one pattern of repeated transmissions to another pattern, or it may be the network device that notifies the terminal device to switch from one pattern of a single transmission to another pattern.
The target signaling may include: one or more combinations of indication information of a repetition Pattern (Pattern), indication information of a transmission method, a handover command, indication information of a target resource, indication information of a number of repeated transmissions, and indication information of a decoding policy.
As a first possible implementation manner, the target signaling includes indication information of a repetition pattern, where the indication information of the repetition pattern corresponds to at least one transmission resource group, and each transmission resource group includes one or more of a search space set (SS set), a control resource set (CORESET), and a PDCCH candidate (candidate) having an association relationship.
The network device may configure two or more repetition patterns through higher layer signaling, such as Radio Resource Control (RRC) signaling, where each repetition pattern is specifically a set of transmission resource groups. The target signaling is then used to indicate at least one of the two or more repetition patterns configured by the RRC signaling, and in some embodiments, the target signaling indicates one of the two or more repetition patterns configured by the RRC signaling.
The at least one transmission resource group may be two or more CORESET having association, or may be two or more SS sets having association, or may be two or more PDCCH candidates having association. The transmission resources in the transmission resource group can be used for receiving the control information by the terminal device in a repeated transmission state.
When a plurality of transmission resources are included in the transmission resource group, the transmission resource group corresponding to the repetition pattern may be changed by activating or deactivating or dynamically instructing the transmission resources, so that the repetition pattern may be changed. Even if the network device always uses the repeated transmission for transmission, the scheduling flexibility of the network device can be increased through the change of the repeated pattern. In addition, the network device may also instruct the terminal to always use a single transmission for transmission, or may increase the flexibility of network device scheduling by changing the repetition pattern.
The at least one transmission resource group may be an SS set, or may be a CORESET, or may be a PDCCH candidate. The transmission resources in the transmission group may be used for the reception of the control information by the terminal device in the single transmission state.
For clarity of illustration of the repetitive pattern, the following examples are given:
pattern 1: SS set2, SS set 3. Pattern1 may be used for repeated transmission and is a repeating Pattern for repeated transmission.
Pattern 2: SS set 2. Pattern 2 may be used for a single transmission and is a repeating Pattern for a single transmission.
Pattern 3: PDCCH candidate index (index)2(AL ═ 8) in SS set2, and PDCCH candidate index 1(AL ═ 8) in SS set 3. Pattern 3 may be used for repeat transmission, where AL denotes aggregation level, which is an optional configuration.
Pattern 4: PDCCH candidate index 2(AL ═ 8) in SS set 2. Pattern4 may be used for a single transmission.
Pattern 5: CORESET 1, CORESET 2. Pattern 5 may be used for repeated transmissions.
Pattern 6: SS set3, SS set 5. Pattern 6 may be used for repeated transmissions.
Pattern 7: PDCCH candidate index 1(AL ═ 8) in SS set 2. Pattern 7 may be used for a single transmission.
Pattern 8: SS set a, SS set b, SS set c. Pattern8 may be used for repeated transmissions.
In the above repetition patterns, each repetition pattern includes one transmission resource, or two or more transmission resources associated with each other.
For example: in addition, because Pattern1 includes two SS sets, namely SS set2 and SS set3, the network device may perform repeated transmission of control information using repeated transmission.
Another example is: in the case where the indication information of the repeated Pattern in the target signaling indicates Pattern4, since the Pattern4 only includes one PDCCH candidate, it indicates that the network device will perform a single transmission or a single transmission of control information. The network device uses Pattern4 when performing a single transmission or a single transmission of control information.
In the following examples: when the Pattern8 is configured in the higher layer signaling, since the Pattern8 includes a plurality of transmission resources, it may be determined to adopt single transmission or repeated transmission according to the number of transmission resources activated or indicated by the indication information of the repeated Pattern in the target signaling. In the case where the transmission resources activated or indicated in Pattern8 are two SS sets, as SS set a and SS set b, it indicates that duplicate transmission is employed. In the case where the transmission resource activated or indicated in Pattern8 is one SS set, it indicates that the repetitive transmission is employed.
As a second possible implementation manner, the target signaling includes indication information of the transmission method. The transmission method comprises the following steps: at least one of an inter-slot repeat transmission, an intra-slot repeat transmission, a non-repeat transmission, and a single frequency network SFN. The transmission method suitable for repeated transmission comprises the following steps: at least one of an inter-slot repeat transmission, an intra-slot repeat transmission, and a single frequency network SFN; the transmission method suitable for single transmission comprises the following steps: non-repetitive transmission. The network device configures two or more transmission methods through high-level signaling, such as RRC signaling, and dynamically indicates one or more transmission methods through target signaling. Wherein the non-repeated transmission correspondence indicates a single transmission; the inter-slot repeat transmission and the intra-slot repeat transmission and SFN correspondence indicate repeat transmission. In some embodiments, the inter-slot transmission may further include: and transmitting control information by using different CORESET/SS set/PDCCH candidates in different time slots, and transmitting control information by using the same CORESET/SS set/PDCCH candidates in different time slots. In some embodiments, the repeating within a slot may further comprise: different CORESET/SS set/PDCCH candidates in the same time slot perform repeated transmission of control information, Single Frequency Network (SFN). The SFN is, among others, to transmit the same control information using the same transmission resource.
As a third possible implementation, a handover command is included in the target signaling to indicate a handover between a single transmission and a repeated transmission. In some application scenarios, when the network device configures the terminal device to perform the repeated transmission of the PDCCH by using the repeated transmission, if the network device needs to switch to the single transmission of the single transmission, a target signaling containing a switching command may be sent to the terminal device, and the terminal is notified to switch to the single transmission of the single transmission.
The above three implementations are merely examples and do not constitute a limitation on the embodiments of the present disclosure. Those skilled in the art will appreciate that the target signaling may be a combination of one or more of the three possible implementations described above. In addition, in the foregoing three implementations, the target signaling may further include one or more combinations of indication information of the target resource, indication information of the number of repeated transmissions, and indication information of the decoding policy. The decoding strategy may include independent decoding and soft combining decoding.
It should be noted that the indication information of the repeated pattern, the indication information of the transmission method, the handover command, the indication information of the target resource, the indication information of the number of times of repeated transmission, the indication information of the decoding policy, and the like included in the target signaling in the foregoing embodiments are equivalent in meaning to the aforementioned handover between single transmission and repeated transmission, and are included in the handover connotation between single transmission and repeated transmission, and belong to the scope of handover between single transmission and repeated transmission.
And 102, receiving the control information of the single transmission or the repeated transmission after switching by adopting target transmission resources.
Wherein the target transmission resource is at least one of:
a pre-configured transmission resource;
the target signaling corresponds to transmission resources in an effective time domain range;
a transmission resource indicated by the target signaling;
and determining the transmission resources according to the transmission resources occupied by the target signaling.
These possible target transmission resources are described separately below.
Firstly, the target signaling corresponds to the transmission resources in the effective time domain range: the target transmission resource may be the entire transmission resource within the effective time domain. For example: the target signaling indicates that the terminal device is switched from the repeated transmission to the single transmission, which means that all transmission resources of the network device in the effective time domain range corresponding to the target signaling adopt the single transmission. For another example, if the network device instructs the terminal device to perform the repeated transmission in one time slot or two consecutive time slots, all transmission resources in the effective time domain range corresponding to the target signaling are subjected to the repeated transmission.
It should be noted that the starting position of the effective time domain range is a set offset after receiving the time slot or symbol of the target signaling; or, the starting position of the valid time domain range is the set offset after the slot or symbol of the hybrid automatic repeat request acknowledgement (HARQ-ACK) corresponding to the transmission target signaling. The set offset is preconfigured or indicated in the target signaling, which is not limited in this embodiment.
Secondly, the preconfigured transmission resource is a transmission resource corresponding to a preconfigured CORESET or SS set or PDCCH candidates. For example: the target signaling instructs the terminal device to perform a single transmission, or multiple transmissions. The network equipment sends the control information according to the predefined CORESET or SS set or PDCCH candidate; correspondingly, the terminal equipment receives the control information according to the predefined CORESET or SS set or PDCCH candidate. For example: the target signaling indicates the terminal device to perform single transmission or repeated transmission of the PDCCH, which means that the network device employs single transmission or repeated transmission in the transmission resource corresponding to the preconfigured CORESET or SS set or PDCCH candidates in the effective time domain range corresponding to the target signaling. For transmission resources not corresponding to the preconfigured CORESET or SS set or PDCCH candidates, the PDCCH transmission manner is not limited, for example, the transmitted PDCCHs are PDCCH single transmission.
And thirdly, the transmission resource indicated by the target signaling. Optionally, in the first implementation manner of the foregoing step 101, the transmission resource indicated by the target signaling includes at least part of transmission resources in at least one transmission resource group corresponding to the indication information of the repetition pattern, specifically, the target signaling includes the indication information of the target transmission resource, and is used to indicate at least part of transmission resources in the transmission resource group corresponding to the indication information of the repetition pattern, and may also be a transmission resource associated with the at least part of transmission resources. Or, optionally, in an implementation manner except the first implementation manner in the foregoing step 101, the target signaling includes indication information of the target transmission resource, which may be used to indicate an index of an SSset or an index of a CORESET or an index of a PDCCH candidate as the target transmission resource.
And fourthly, determining the transmission resources according to the transmission resources occupied by the target signaling. Optionally, in the first implementation manner of the foregoing step 101, the determining, according to the transmission resource occupied by the target signaling, a transmission resource includes: one or more transmission resources in SS set, CORESET and PDCCH candidates occupied by the target signaling; and/or, the transmission resource which is the same as or has the incidence relation with one or more of the SS set, the CORESET and the PDCCH candidate occupied by the target signaling.
Based on the foregoing manner, after determining the target transmission resource adopted by the network device, the terminal device receives the control information transmitted by the network device in a single transmission or repeated transmission according to the target transmission resource.
It should be noted that, the control information of the repeated transmission mentioned in the embodiments of the present disclosure is not limited to that the control information of each transmission in the repeated transmission is completely the same, and the control information of different transmissions is allowed to be partially different. For example, the contents of some information fields are not completely the same, or the formats of the control information are different, or an information field exists in a certain control information and the information field does not exist in another control information. As long as two or more pieces of control information are used for scheduling or indicating the same physical channel or physical signal, they may be regarded as repeatedly transmitted control information.
In the embodiment of the disclosure, the network device sends the target signaling to notify the terminal device of the switching between single transmission and repeated transmission, and after receiving the target signaling, the terminal device can determine that the target transmission resource is at least one of a pre-configured transmission resource, a transmission resource in an effective time domain range corresponding to the target signaling, a transmission resource indicated by the target signaling, and a transmission resource determined according to a transmission resource occupied by the target signaling, so that the terminal device can receive the control information of the switched single transmission or repeated transmission by using the target transmission resource.
Fig. 2 is a schematic flowchart of another resource determining method provided in the embodiment of the present disclosure, where the method is used for a terminal device, and as shown in fig. 2, the method includes the following steps:
step 201, receiving a target signaling sent by a network device, where the target signaling is used to notify a handover between single transmission and repeated transmission of a PDCCH.
For the related description of the information carried by the target signaling, reference may be made to the foregoing embodiments, which are not described in detail in this embodiment.
In this embodiment, a signaling format of the target signaling is described.
As a possible implementation, the target signaling may specifically be DCI. The DCI may include indication information of a transmission method, indication information of a repetition pattern, and may further include a handover command. For example, the handover command may occupy 1 bit. The DCI may include information indicating the number of repeated transmissions and information indicating a decoding policy.
It should be noted that, the decoding strategy, i.e. the decoding method, here, for example: soft combining decoding, independent decoding (also called selective decoding), etc. When the network device instructs the terminal device to perform independent decoding through the target signaling, the network device can switch between single transmission and repeated transmission in an implementation manner without affecting the decoding of the terminal device. When the network device instructs the terminal device to perform soft combining decoding through the target signaling, the network device needs to notify the terminal device of the switching, otherwise, a decoding error of the terminal device occurs. Therefore, the network device side can also realize the switching between the single transmission and the repeated transmission of the PDCCH by informing the terminal decoding strategy.
As another possible implementation, the target signaling may specifically be a MAC CE. The MAC CE may include one or more combinations of indication information of a transmission method, indication information of a repetition pattern, a handover command, indication information of a target transmission resource, indication information of a number of repeated transmissions, and a decoding policy.
In some embodiments, the MAC CE may be used with RRC sent by the network device.
For example: the indication information of the transmission method included in the MAC CE may be in the form of a bitmap (bitmap) by which one or more transmission methods among the plurality of transmission methods configured by the RRC are indicated.
Another example is: a repetition Pattern is configured by RRC, the repetition Pattern includes two or more indexes of the core set or SS set or PDCCH candidate, for example, Pattern8 mentioned in the corresponding embodiment of fig. 1, and the indication information of the repetition Pattern included in the MAC CE may be in the form of bit mapping, and a part of transmission resources in the repetition Pattern configured by RRC is indicated by bit mapping. The indicated partial transmission resource may be an SS set index, or an index of a PDCCH candidate, etc.
In other embodiments, if the network device does not send the RRC configuration with multiple transmission methods and does not configure the repetition pattern, the network device may only use the MAC CE to indicate the target transmission resource.
For example: the indication information of the target transmission resource contained in the MAC CE may be in the form of a bitmap by which the SS set index is indicated. The SS sets that the bit map may indicate may be all SS sets, or the SS sets to be monitored. And after receiving the MAC CE, the terminal equipment determines the target transmission resource according to the bit mapping.
Alternatively, the SS set index and/or the index of the PDCCH candidate, which is information indicating the target transmission resource included in the MAC CE. After receiving the MAC CE, the terminal device may determine that the control information is transmitted on the target transmission resource indicated by the MAC CE.
Step 202, determining an effective time domain range according to the target signaling.
The valid time domain range is a set offset after the receiving position of the target signaling or the sending position of the corresponding HARQ-ACK, for example: this set offset may be K slots and/or L symbols, where K and L are integers greater than or equal to zero, that is, non-negative integers. Another example is: this set offset may be one or more CORESET or SS sets or the duration of the monitoring opportunity within a timeslot.
As a first possible implementation manner, the set offset may be a scheduling offset (scheduling offset) or an indication offset predefined in a communication standard protocol, for example: can be
Figure BDA0002903953710000061
A time slot therein
Figure BDA0002903953710000062
The number of slots included in one subframe is configured for the subcarrier spacing, and the subcarrier spacing of a PUCCH (physical uplink control channel) carrying HARQ-ACK is configured for the subcarrier spacing.
It should be noted that the aforementioned receiving location may be a time slot or a symbol, or other resources for receiving the target signaling; similarly, the aforementioned transmission position may be a slot or a symbol, and may also be other resources for transmitting HARQ-ACK.
As a second possible implementation, the set offset may be indicated in the target signaling.
Step 203, detecting the target transmission resource in the effective time domain range to obtain the control information sent by the network device by adopting single transmission or repeated transmission.
In one scenario, the network device has configured a repetition pattern or transmission pattern through RRC. And if the indication information of the repeated pattern in the MAC CE indicates the SS set, detecting the target transmission resource of each time slot within the effective time domain range to obtain the control information sent by the network equipment by adopting single transmission or repeated transmission.
As a possible implementation manner, according to the SS set indicated by the target signaling and serving as the target transmission resource, the SS set indicated by the target signaling and in a state to be monitored is detected for each timeslot. And if the SS set corresponding to the indication information of the repeated style is in a state to be monitored in the current time slot, the terminal equipment detects the SS set to obtain control information. And if the SS set corresponding to the indication information of the repeated pattern is not in the state to be monitored in the current time slot, the terminal equipment does not detect the SS set.
As another possible implementation manner, according to the SS set indicated by the target signaling and serving as the target transmission resource, the SS set indicated by the target signaling and in the state to be monitored is detected for each timeslot, and the SS set indicated by the target signaling and not in the state to be monitored is detected. And if the SS set corresponding to the indication information of the repeated style is in a state to be monitored in the current time slot, the terminal equipment detects the SS set to obtain control information. And if the SS set corresponding to the indication information of the repeated pattern is not in the state to be monitored in the current time slot, the terminal equipment still detects the SS set. Thereby avoiding missed detection or the occurrence of a condition that the determination of the monitorable PDCCH candidate set is wrong.
As another possible implementation manner, each SS set indicated by the target signaling is detected according to the SS set indicated by the target signaling as the target transmission resource. For the terminal device, the detection may be performed according to the SS set indicated by the target signaling, so as to receive the control information sent by the network device.
In the embodiment of the disclosure, the network device sends the target signaling to notify the terminal device of the switching between single transmission and repeated transmission, and after receiving the target signaling, the terminal device can determine that the target transmission resource is at least one of a pre-configured transmission resource, a transmission resource in an effective time domain range corresponding to the target signaling, a transmission resource indicated by the target signaling, and a transmission resource determined according to a transmission resource occupied by the target signaling, so that the terminal device can receive the control information of the switched single transmission or repeated transmission by using the target transmission resource.
Fig. 3 is a schematic flowchart of another resource determining method provided in the embodiment of the present disclosure, where the method is used for a terminal device, and as shown in fig. 3, the method includes the following steps:
step 301, receiving a target signaling sent by a network device and indicating to switch to single transmission.
The network device may configure the repeat pattern using RRC, and if the network device configures a repeat pattern for repeated transmission, it needs to switch to single transmission. The network device sends a target signaling to the terminal device to switch to a single transmission. The target signaling may only contain a handover command.
It should be noted that, the network device may enable the terminal device to perform the repeat transmission by using the repeat pattern configured by the network device through the target signaling for indicating the repeat transmission mentioned in the foregoing implementation, where the target signaling includes, but is not limited to, the MAC CE or DCI, and the content carried in the target signaling may be indication information of the repeat pattern, where a set of transmission resource groups corresponding to the indication information of the repeat pattern includes multiple transmission resources. Other target signaling for indicating repeat transmission, which may be determined by one skilled in the art in conjunction with the foregoing embodiments, are within the scope of the embodiments of the present disclosure. Similarly, other target signaling for indicating a single transmission, which may be determined by one skilled in the art in conjunction with the foregoing embodiments, are also within the scope of the embodiments of the present disclosure.
Step 302, detecting the target transmission resource of single transmission in each time slot to obtain the control information sent by the network device by using the single transmission.
In the target signaling sent by the network device for switching to the single transmission, if the target transmission resource of the single transmission is not described, there may be several possible implementations as follows.
As a first possible implementation manner, in a case that the target signaling does not indicate a target transmission resource for a single transmission, part of transmission resources set in the repetition pattern are detected to obtain control information sent by the network device by using the single transmission. By the method, a smaller resource range can be determined, and the control information can be acquired quickly.
For example: and the terminal equipment takes the first transmission resource or the second transmission resource in one transmission resource group corresponding to the indication information of the repeated pattern as the target transmission resource of single transmission.
As a second possible implementation manner, all transmission resources in the target transmission resources are detected to obtain the control information sent by the network device by using a single transmission. The terminal device may perform blind detection with all transmission resources in the transmission resource group corresponding to the indication information of the repeated pattern as target transmission resources.
As a third possible implementation manner, each transmission resource in the effective time domain range is detected to obtain the control information sent by the network device by using the single transmission. That is, when performing single transmission, the terminal device may ignore the transmission resource group indicated by the indication information of the repeated pattern configured by the network device, and determine the PDCCH transmission resource only according to the indication of the single transmission, that is, all the SS sets to be monitored are considered to be possibly used for transmission of the control information. And the terminal equipment detects all the transmission resources in the effective time domain range to avoid the condition of missing detection.
In some embodiments, after performing the handover between single transmission and repeated transmission, the maximum number of PDCCH candidates that can be monitored for each slot, i.e. the upper limit of the number of detections, can be adjusted accordingly.
The terminal device may determine an upper limit of the number of detections of the monitorable PDCCH candidate for each slot according to the target signaling. Wherein the upper limit of the number of detections of the PDCCH candidate that can be monitored during the repeated transmission is greater than the upper limit of the number of detections of the PDCCH candidate that can be monitored during the single transmission.
Alternatively, the terminal device may determine the upper limit of the number of detections of the monitorable transmission resource group for each timeslot according to the target signaling.
Or, two or more groups of transmission resource groups, and the detectable PDCCH candidates and the upper limit of the detection times thereof corresponding to each group of transmission resource groups are determined according to the instruction of the target signaling for repeated transmission. Two or more SS sets, CORESET or PDCCH candidates in the transmission resource group configured by the network device may be respectively in different transmission resource groups, each transmission group corresponds to one TRP, that is, the transmission resources in the transmission group are available for the corresponding TRP.
In the following, a description will be given by taking an example that the terminal device determines the upper limit of the number of detections of the monitorable PDCCH candidate for each slot according to the target signaling, and those skilled in the art can know that, with reference to the following determination manner, the determination manner of the upper limit of the number of detections of the transmission resource group and the upper limit of the number of detections of the transmission resource group can be obtained.
In one scenario, a network device indicates a repetition pattern to a terminal through target signaling, and the terminal device may determine on which TRP a PDCCH is transmitted according to an association relationship between a transmission resource indicated in the repetition pattern and the TRP, for example: the target signaling described in the foregoing embodiments includes indication information of a repetition pattern. In this case, the terminal device may determine an upper limit of the number of detections for each TRP (transmission resource packet). Optionally, the upper limit of the number of detections for each timeslot is determined according to the number of changes of the target transmission resource before and after the handover. For example: the indication information of the repeated pattern in the target signaling indicates that the SS set1 and the SS set2 which are associated with each other are used as target transmission resources, in the case of single transmission, the transmission is only performed on the SS set1, and in the corresponding time slot, the PDCCH candidate to be monitored contained in the SS set2 can be subtracted as the maximum blind detection number of the terminal device in the corresponding time slot, that is, the upper limit of the detection number.
In another scenario, the network device does not notify the terminal of the transmission resource used by the PDCCH. For example: as described in the foregoing embodiments, the target signaling includes a handover command or a transmission method. In this case, the terminal device may determine the upper limit of the number of detections in several possible ways:
as a first possible implementation manner, the number of the target transmission resources used for the repeated transmission is determined. For example, the upper limit of the number of detections for a single transmission may be half the upper limit of the number of detections for a repeated transmission.
As a second possible implementation, the configuration is performed by a network device. In some embodiments, only part of the PDCCH is converted into a single transmission, and part of the PDCCH still exists for repeated transmission, in which case, the upper limit of the detection times may be configured or indicated by the network device.
As a third possible implementation, the number of detections remains unchanged. The terminal equipment converts the decoding mode into independent decoding, detects all PDCCHs in the time slot, namely all PDCCHs in the time slot are used as target transmission resources, and under the condition, the upper limit of the detection times is kept unchanged.
Similarly to the first implementation, there is a fourth possible implementation, which is also determined according to the number of target transmission resources used for repeated transmission. The upper limit of the detection times in single transmission is that the repeated transmission is half of the upper limit of the detection times minus A, wherein A is the blind detection times determined according to all the transmission resources which are configured by the network equipment and have the association relationship.
And the terminal equipment determines two or more groups of transmission resources and the upper limit of the detection times of the monitorable PDCCH candidates corresponding to each group of transmission resources according to the instruction of PDCCH repeated transmission of the target signaling. For example, each set of transmission resources is one or more CORESET, each CORESET is associated with one TRP, for example, coresetpoolndex-r 16 may be configured in the CORESET, a value of the higher layer parameter may be 0 or 1, the CORESET with a value of 0 may correspond to one TRP, and the CORESET with a value of 1 may correspond to another TRP. Therefore, the terminal device may determine the upper limit of the detection times of the monitored PDCCH candidates corresponding to each CORESET group, that is, the upper limit of the detection times of the monitored PDCCH candidates on the CORESET with the higher layer parameter coresetpoolndex-r 16 being taken as 0, and the upper limit of the detection times of the monitored PDCCH candidates on the CORESET with the higher layer parameter coresetpoolndex-r 16 being taken as 0.
For example: the network device side indicates the terminal to perform single PDCCH transmission on only one of the CORESET groups through target signaling, and then the terminal may determine that the maximum number of monitored PDCCH candidates of another CORESET group is 0.
It should be noted that, in some cases, the transmission resource set configured by the network device includes two or more SS sets, core sets, or PDCCH candidates, and the two or more SS sets, core sets, or PDCCH candidates are respectively located in different transmission resource groups. In other cases, if one SS set, core set, or PDCCH candidate in the transmission resource set configured by the network device is in a monitorable state, the terminal device may consider another SS set, core set, or PDCCH candidate associated with the transmission resource set to be in a monitorable state. Or, in still other cases, the set of transmission resources configured by the network device is a set of monitorable transmission resources, and each transmission resource in the set of transmission resources is a monitorable PDCCH candidate.
In the embodiment of the disclosure, the network device sends the target signaling to notify the terminal device of the switching between single transmission and repeated transmission, and after receiving the target signaling, the terminal device can determine that the target transmission resource is at least one of a pre-configured transmission resource, a transmission resource in an effective time domain range corresponding to the target signaling, a transmission resource indicated by the target signaling, and a transmission resource determined according to a transmission resource occupied by the target signaling, so that the terminal device can receive the control information of the switched single transmission or repeated transmission by using the target transmission resource.
Fig. 4 is a schematic flowchart of another resource determining method provided in an embodiment of the present invention, where the method is used for a terminal device, and as shown in fig. 4, the method includes the following steps:
step 401, receiving a target signaling sent by a network device, where the target signaling includes indication information of a TCI status or a TCI status for activation.
As a possible implementation manner, if a set of transmission resource groups corresponding to the preset repeating pattern of the network device is within one SS set, or a scheme of repeating transmission within the CORESET is adopted, one CORESET activates up to two TCI states. Thus, one or two PDCCHs can be determined to be transmitted, i.e., single transmission or repeated transmission, according to the number of TCI states activated by the CRESSET.
As another possible implementation, the target signaling may also be used to indicate the TCI status, for example: common TCI status. So that it can be determined to transmit one or two PDCCHs, i.e., a single transmission or a repeated transmission, according to the number of indicated TCI states.
It should be noted that the number of target transmission resources may be larger than the number of PDCCHs, and the two are not equivalent concepts. There is a corresponding relationship between the number of PDCCHs and the number of transmission times of control information, for example: one PDCCH may be a single transmission and two PDCCHs may be repeated transmissions.
Step 402, determining switching between single transmission and repeated transmission of the PDCCH according to the number of TCI states, and receiving control information sent by the network device by using single transmission or repeated transmission by using a target transmission resource.
And receiving the control information sent by the network equipment by adopting the single transmission or the repeated transmission on one or more PDCCHs carrying the control information by adopting target transmission resources. The number of PDCCHs carrying the control information is determined according to the number of TCI states activated by the target signaling in CORESET configured by network equipment; or, the number of PDCCHs carrying the control information is determined according to the number of TCIs in the common TCI state indicated by the target signaling.
Corresponding to one possible implementation of the foregoing steps, the target signaling is used to activate the TCI state in CORESET. And according to the number of the activated TCI states in the CORESET, carrying the PDCCH number of the control information. For example: and activating a TCI state, and determining that the network equipment only sends control information on the resource where the first PDCCH candidate or SS set or CORESET is located in the transmission resource group pre-configured by the network equipment, but not sending the control information on other transmission resources. For another example, one or more CORESET activates one TCI state, one or more CORESET activates two TCI states, and the terminal device determines that PDCCH transmissions performed in the CORESET activating one TCI state are both PDCCH single transmissions, and PDCCH transmissions performed in the CORESET activating two TCI states are both PDCCH repeated transmissions.
Corresponding to another possible implementation manner in the foregoing steps, the target signaling is used to indicate a common TCI state, that is, an indication of a common beam (common beam), and a transmission position or number of PDCCHs may be determined according to the number of TCI states indicated in the common TCI state.
For example: the common TCI status indicates a TCI status, which is used to indicate the TCI statuses of the PDSCH and the PDCCH, and the terminal device may determine that the network device only uses one PDCCH for transmission, specifically, the terminal device may use the first PDCCH candidate or SS set or CORESET in a group of transmission resource groups configured by the network device, or all transmission resources within the action range of the common TCI status use one PDCCH for transmission. The common TCI status indicates two TCI statuses, indicating that the network device will make repeated transmissions.
In the embodiment of the disclosure, the network device sends the target signaling to notify the terminal device of the switching between single transmission and repeated transmission, and after receiving the target signaling, the terminal device can determine that the target transmission resource is at least one of a pre-configured transmission resource, a transmission resource in an effective time domain range corresponding to the target signaling, a transmission resource indicated by the target signaling, and a transmission resource determined according to a transmission resource occupied by the target signaling, so that the terminal device can receive the control information of the switched single transmission or repeated transmission by using the target transmission resource.
Fig. 5 is a schematic flowchart of a resource determining method according to an embodiment of the present invention, where the method is used for a network device, and as shown in fig. 5, the method includes the following steps:
step 501, sending a target signaling to a terminal device, where the target signaling is used to notify switching between single transmission and repeated transmission of a PDCCH.
Step 502, sending the control information of the single transmission or the repeated transmission to the terminal device by using the target transmission resource.
Wherein the target transmission resource is at least one of:
a pre-configured transmission resource;
the target signaling corresponds to transmission resources in an effective time domain range;
a transmission resource indicated by the target signaling;
and determining the transmission resources according to the transmission resources occupied by the target signaling.
For the description of the related content in this embodiment, reference is made to the content in the embodiment corresponding to fig. 1, which is not described again in this embodiment.
In the embodiment of the disclosure, a network device sends a target signaling to notify a terminal device of switching between single transmission and repeated transmission, and after receiving the target signaling, the terminal device may determine that the target transmission resource is at least one of a pre-configured transmission resource, a transmission resource in an effective time domain range corresponding to the target signaling, a transmission resource indicated by the target signaling, and a transmission resource determined according to a transmission resource occupied by the target signaling, so that the terminal device may receive control information of single transmission or repeated transmission after switching by using the target transmission resource.
Fig. 6 is a schematic flowchart of another resource determining method provided in an embodiment of the present disclosure, where the method is used for a network device, and as shown in fig. 6, the method includes the following steps:
step 601, sending a target signaling to the terminal device, where the target signaling is used to notify switching between single transmission and repeated transmission of the PDCCH.
For the related description of the information carried by the target signaling, reference may be made to the foregoing embodiments, which are not described in detail in this embodiment.
In this embodiment, a signaling format of the target signaling is described.
As a possible implementation, the target signaling may specifically be DCI. The DCI may include indication information of a transmission method, indication information of a repetition pattern, and may further include a handover command. The switching command may specifically occupy 1 bit. DCI may include information indicating the number of repeated transmissions, information indicating a decoding policy, and the like.
Here, the decoding strategy, i.e., the decoding method, is, for example: soft combining decoding, independent decoding (also called selective decoding), etc. When the network device instructs the terminal device to perform independent decoding through the target signaling, the network device can switch between single transmission and repeated transmission in an implementation manner without affecting the decoding of the terminal device. When the network device instructs the terminal device to perform soft combining decoding through the target signaling, the network device needs to notify the terminal device of the switching, otherwise, a decoding error of the terminal device occurs.
As another possible implementation, the target signaling may specifically be a MAC CE. The MAC CE may include one or more combinations of indication information of a transmission method, indication information of a repetition pattern, a handover command, indication information of a target transmission resource, indication information of a number of repeated transmissions, and a decoding policy.
In some embodiments, the MAC CE may be used with RRC sent by the network device.
For example: the indication information of the transmission method included in the MAC CE may be in the form of a bitmap (bitmap) by which one or more transmission methods among the plurality of transmission methods configured by the RRC are indicated.
Another example is: a repetition Pattern is configured by RRC, the repetition Pattern includes two or more indexes of the core set or SS set or PDCCH candidate, for example, Pattern8 mentioned in the corresponding embodiment of fig. 1, and the indication information of the repetition Pattern included in the MAC CE may be in the form of bit mapping, and a part of transmission resources in the repetition Pattern configured by RRC is indicated by bit mapping. The indicated partial transmission resource may be an SS set index, or an index of a PDCCH candidate, etc.
In other embodiments, if the network device does not send the RRC configuration with multiple transmission methods and does not configure the repetition pattern, the network device may only use the MAC CE to indicate the target transmission resource.
For example: the indication information of the target transmission resource contained in the MAC CE may be in the form of a bitmap by which the SS set index is indicated. The SS sets that the bit map may indicate may be all SS sets, or the SS sets to be monitored. And after receiving the MAC CE, the terminal equipment determines the target transmission resource according to the bit mapping.
Alternatively, the SS set index, which is information indicating the target transmission resource included in the MAC CE. After receiving the MAC CE, the terminal device may determine that the control information is transmitted on the target transmission resource indicated by the MAC CE.
Step 602, in the effective time domain range, sending the control information adopting single transmission or repeated transmission to the terminal equipment.
The valid time domain range is a set target signaling receiving time or a set offset after the corresponding HARQ-ACK is sent, for example: this set offset may be K slots and/or L symbols, where K and L are integers greater than or equal to zero, that is, non-negative integers. Another example is: this set offset may be one or more CORESET or SS sets or the duration of the monitoring opportunity within a timeslot.
The description of the related content in this embodiment refers to the content in the embodiment corresponding to fig. 2, which is not repeated in this embodiment.
In the embodiment of the disclosure, the network device sends the target signaling to notify the terminal device of the switching between single transmission and repeated transmission, and after receiving the target signaling, the terminal device can determine that the target transmission resource is at least one of a pre-configured transmission resource, a transmission resource in an effective time domain range corresponding to the target signaling, a transmission resource indicated by the target signaling, and a transmission resource determined according to a transmission resource occupied by the target signaling, so that the terminal device can receive the control information of the switched single transmission or repeated transmission by using the target transmission resource.
Fig. 7 is a flowchart illustrating another resource determining method provided in an embodiment of the present disclosure, where the method is used for a network device, and as shown in fig. 7, the method includes the following steps:
step 701, sending a target signaling for indicating switching to single transmission to the terminal device.
The network device may configure the repeat pattern using RRC, and if the network device performs a repeat transmission using one of the configured repeat patterns, it needs to switch to a single transmission. The network device sends a target signaling to the terminal device to switch to a single transmission. The target signaling may only contain a handover command.
Step 702, in each time slot, a single transmission target transmission resource is adopted to send single transmission control information to the terminal device.
In the target signaling sent by the network device for switching to the single transmission, if the target transmission resource of the single transmission is not described, there may be several possible implementations as follows.
As a first possible implementation manner, a part of transmission resources set in the target transmission resource is detected to obtain control information sent by the network device by using the single transmission. By the method, a smaller resource range can be determined, and the control information can be acquired quickly.
For example: and the terminal equipment takes the first transmission resource or the second transmission resource in one transmission resource group corresponding to the indication information of the repeated pattern as the target transmission resource of single transmission.
As a second possible implementation manner, all transmission resources in the target transmission resources are detected to obtain the control information sent by the network device by using a single transmission. The terminal device may perform blind detection with all transmission resources in the transmission resource group corresponding to the indication information of the repeated pattern as target transmission resources.
As a third possible implementation manner, each transmission resource in the effective time domain range is detected to obtain the control information sent by the network device by using the single transmission. The terminal device may ignore the set of transmission resources indicated by the indication information of the repeated pattern configured by the network device, and all the SS sets to be monitored are considered to be possibly used for transmission of the control information. And the terminal equipment detects all the transmission resources in the effective time domain range to avoid the condition of missing detection.
The description of the related content in this embodiment refers to the content in the embodiment corresponding to fig. 3, which is not repeated in this embodiment.
In the embodiment of the disclosure, the network device sends the target signaling to notify the terminal device of the switching between single transmission and repeated transmission, and after receiving the target signaling, the terminal device can determine that the target transmission resource is at least one of a pre-configured transmission resource, a transmission resource in an effective time domain range corresponding to the target signaling, a transmission resource indicated by the target signaling, and a transmission resource determined according to a transmission resource occupied by the target signaling, so that the terminal device can receive the control information of the switched single transmission or repeated transmission by using the target transmission resource.
Fig. 8 is a flowchart illustrating another resource determining method provided in an embodiment of the present disclosure, where the method is used for a network device, and as shown in fig. 8, the method includes the following steps:
step 801, target signaling is sent to a network device, where the target signaling includes indication information of a TCI status or a TCI status for activation.
As a possible implementation manner, if the network sets a set of transmission resource groups corresponding to the preconfigured repeat pattern in one SS set, or adopts a scheme of repeat transmission in the CORESET, one CORESET activates up to two TCI states. Thus, one or two PDCCHs can be determined to be transmitted, i.e., single transmission or repeated transmission, according to the number of TCI states activated by the CRESSET. For example: and activating a TCI state, and determining that the network equipment only sends control information on the resource where the first PDCCH candidate or SS set or CORESET is located in the transmission resource group preset by the network equipment, but not sending the control information on other transmission resources by the terminal equipment.
As another possible implementation, the target signaling may also be used to indicate the TCI status, for example: common TCI status. So that it can be determined to transmit one or two PDCCHs, i.e., a single transmission or a repeated transmission, according to the number of indicated TCI states. For example: the common TCI status indicates a TCI status, which is used to indicate the TCI statuses of the PDSCH and the PDCCH, and the terminal device may determine that the network device only uses one PDCCH for transmission, specifically, the terminal device may determine that the network device uses the first PDCCH candidate or SS set or CORESET in a set of transmission resource groups configured by the network device. The common TCI status indicates two TCI statuses, indicating that the network device will make repeated transmissions.
The network equipment sends the control information by adopting the single transmission or the repeated transmission on one or more PDCCHs bearing the control information by adopting the target transmission resource; the number of the PDCCHs for bearing the control information is determined according to the number of TCI states activated by the target signaling in CORESET configured by network equipment; or, the number of PDCCHs carrying the control information is determined according to the number of TCIs in the common TCI state indicated by the target signaling.
It should be noted that the number of target transmission resources may be larger than the number of PDCCHs, and the two are not equivalent concepts. There is a corresponding relationship between the number of PDCCHs and the number of transmission times of control information, for example: one PDCCH may be a single transmission and two PDCCHs may be repeated transmissions.
