The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present disclosure and should not be construed as limiting the present disclosure.

[0051] A physical uplink control channel PUCCH resource indication method, apparatus, communication device, and storage medium provided by the present disclosure will be described in detail below with reference to the accompanying drawings.

[0052] Figure 1 It is a schematic diagram of a PUCCH resource indication method proposed according to the present disclosure. It should be noted that the PUCCH resource indication method of the present disclosure can be executed by a user equipment (UE).

[0053] As Figure 1 shown, the PUCCH resource indication method proposed by the present disclosure may include:

[0054] Step 101, obtain a target PUCCH resource indicated for the UE to support joint transmission of multiple transmission and reception points (TRPs) facing the base station.

[0055] In all embodiments of the present disclosure, the method can also be applied to a technical solution of joint transmission of multiple antenna panels panel. That is, step 101 is: obtaining a target PUCCH resource that supports joint transmission of multiple antenna panels panel for the UE and is indicated by the base station.

[0056] In all embodiments of the present disclosure, the method can also be applied to any technical solution of joint transmission. That is, step 101 is: obtaining a target PUCCH resource that supports joint transmission for the UE and is indicated by the base station.

[0057] In some embodiments of the present disclosure, the target PUCCH resource that supports joint transmission of multiple TRPs (Transmission Receive Points) for the UE and is indicated by the base station can be determined according to the control signaling sent to the UE. That is, in one embodiment, the target PUCCH resource that supports joint transmission of multiple transmission receive points TRP for the UE and is indicated by the base station can be determined according to the control signaling sent to the UE. In another embodiment, the target PUCCH resource that supports joint transmission of multiple panel for the UE and is indicated by the base station can be determined according to the control signaling sent to the UE. In yet another embodiment, the target PUCCH resource that supports joint transmission for the UE and is indicated by the base station can be determined according to the control signaling sent to the UE.

[0058] In one embodiment, the control signaling can carry the target PUCCH resource that supports joint transmission of multiple TRPs for the UE and is indicated by the base station. In another embodiment, the control signaling can also carry the target PUCCH resource that supports joint transmission of multiple panel for the UE and is indicated by the base station. In some other embodiments, the control signaling can further carry the target PUCCH resource that supports joint transmission of multiple panel and multiple TRPs for the UE and is indicated by the base station. In some other embodiments, the control signaling can further carry the target PUCCH resource that supports joint transmission for the UE and is indicated by the base station.

[0059] After the UE obtains the control signaling, it can determine the target PUCCH resource that supports joint transmission of multiple transmission receive points TRP for the UE and is indicated by the base station based on the control signaling. Or, after the UE obtains the control signaling, it can determine the target PUCCH resource that supports joint transmission of multiple antenna panels panel for the UE and is indicated by the base station based on the control signaling. Or, after the UE obtains the control signaling, it can determine the target PUCCH resource that supports joint transmission for the UE and is indicated by the base station based on the control signaling.

[0060] The above control signaling may be high-layer signaling. Among them, the high-layer signaling includes radio resource control (RRC) signaling and / or medium access control (MAC) control element (CE) MAC-CE signaling.

[0061] Among them, the above target PUCCH resources may be one or more, and this embodiment does not make specific limitations on this. In actual applications, the number of target PUCCH resources can be indicated according to actual needs.

[0062] In some embodiments, when the target PUCCH resource is one, in order to enable multiple transmissions, the above target PUCCH resource may correspond to multiple different beams. For example, the above target PUCCH resource may correspond to two different beams. That is, in one embodiment, in order to implement multi-TRP transmission, this one target PUCCH resource may correspond to multiple different beams. In order to support joint transmission of multiple antenna panels, this one target PUCCH resource may correspond to multiple different beams.

[0063] In other embodiments, when the target PUCCH resources are multiple, the above multiple target PUCCH resources may correspond to one beam, or multiple different beams, and this embodiment does not make specific limitations on this.

[0064] For example, the above target PUCCH resources are two, each target PUCCH resource is one beam for itself, or each target PUCCH resource corresponds to two beams respectively, or one of the two target PUCCH resources corresponds to one beam, while the other target PUCCH resource corresponds to two beams.

[0065] Among them, it can be understood that different PUCCH resources may correspond to different PUCCH formats. Of course, different PUCCH resources may also correspond to the same PUCCH format.

[0066] PUCCH is a physical channel in the uplink of the New Radio (NR) system, which carries uplink control information (UCI).

[0067] In order to support transmissions with different UCI bit number ranges, 5 PUCCH frame formats are defined in the NR system. Among them, examples of the parameters of PUCCH in the PUCCH format are shown in Table 1.

[0068] Table 1 Parameters of PUCCH in the PUCCH format

[0069]

[0070] As can be seen from Table 1 above, among them, PUCCH format 0 and 1 can only carry data less than or equal to 2 bits, while PUCCH format 2 / 3 / 4 can carry data greater than 2 bits.

[0071] It can be understood that each element and each corresponding relationship in Table 1 exist independently; these elements and corresponding relationships are exemplarily listed in the same table, but it does not mean that all elements and corresponding relationships in the table must exist simultaneously as shown in Table 1. The value of each element and each corresponding relationship is independent of the values of any other elements or corresponding relationships in Table 1. Therefore, those skilled in the art can understand that the value of each element and each corresponding relationship in Table 1 are all independent embodiments.

[0072] In some exemplary embodiments of the present disclosure, the above PUCCH resource includes at least one of the following parameters:

[0073] pucch-ResourceId: PUCCH resource index

[0074] startingPRB (Physical Resource Block): starting PRB index

[0075] intraSlotFrequencyHopping: inter-slot frequency hopping mode

[0076] format: configured PUCCH format, from format 0 to format 4.

[0077] Step 102: Use the target PUCCH resource to repeatedly send uplink control information UCI to multiple transmission and reception points TRP of the base station within one time slot or between multiple time slots.

[0078] In all embodiments of the present disclosure, this solution can also be applied to joint transmission of multiple antenna panels panel. That is, Step 102 is: Use the target PUCCH resource to repeatedly send uplink control information UCI to multiple panels of the base station within one time slot or between multiple time slots.

[0079] In all embodiments of the present disclosure, this solution can also be applied to any transmission scheme of joint transmission. That is, Step 102 is: Use the target PUCCH resource to repeatedly send uplink control information UCI to joint transmission of the base station within one time slot or between multiple time slots.

[0080] In the case where there are multiple target PUCCH resources as described above, in order to improve the transmission quality, there is no overlap in the time-frequency domain between the multiple target PUCCH resources. Of course, in the case where there are multiple target PUCCH resources as described above, there is not a complete overlap in the time-frequency domain between the multiple target PUCCH resources.

[0081] In some embodiments, in a service scenario where a target PUCCH resource is indicated to a UE for transmitting UCI and a single time slot is used for repeated transmission, the UE may repeat the transmission of the target PUCCH resource within a preset number of time slots (such as a single time slot) according to the number of repeated transmissions N of the target PUCCH resource, so as to achieve the retransmission of UCI.

[0082] For example, in the case where there is one target PUCCH resource and the number of repeated transmissions is two, an example of the repeated transmission of the target PUCCH resource carrying the same UCI within a single time slot is as Figure 2 shown.

[0083] It should be noted that in one embodiment of the present invention, the above target PUCCH resource corresponds to multiple different beams that support joint transmission by multiple transmission and reception points (TRPs) of the base station. In another embodiment, the above target PUCCH resource corresponds to multiple different beams that support joint transmission by multiple panels of the base station. In yet another embodiment, the above target PUCCH resource corresponds to multiple different beams that support joint transmission.

[0084] Among them, the number of transmissions in the transmission opportunities corresponding to different beams can be obtained by dividing the number of repeated transmissions N of the target PUCCH resource according to a preset rule.

[0085] In some other embodiments, when using one target PUCCH resource to transmit UCI and repeatedly transmitting the uplink control information (UCI) to multiple TRPs of the base station among multiple time slots, the UE may repeatedly transmit the target PUCCH resource carrying the UCI among multiple time slots according to the number of repeated transmissions N of the target PUCCH resource. Here, N is an integer greater than 1.

[0086] In still some other embodiments, when using one target PUCCH resource to transmit UCI and repeatedly transmitting the uplink control information (UCI) to multiple panels of the base station among multiple time slots, the UE may repeatedly transmit the target PUCCH resource carrying the UCI among multiple time slots according to the number of repeated transmissions N of the target PUCCH resource. Here, N is an integer greater than 1.

[0087] It can be understood that in order to improve the transmission reliability, the above multiple time slots are adjacent in sequence, that is to say, the above multiple time slots are continuous.

[0088] In some other embodiments, in a scenario where multiple target PUCCH resources are used to transmit UCI and multiple time slots are used for repeated transmission, the UE can obtain the number of repeated transmissions for each target PUCCH resource, and based on the number of repeated transmissions for each target PUCCH resource, repeatedly transmit the uplink control information UCI to multiple transmission and reception points (TRPs) of the base station in multiple time slots.

[0089] In another embodiment, in a scenario where multiple target PUCCH resources are used to transmit UCI and multiple time slots are used for repeated transmission, the UE can obtain the number of repeated transmissions for each target PUCCH resource, and based on the number of repeated transmissions for each target PUCCH resource, repeatedly transmit the uplink control information UCI to multiple panels of the base station in multiple time slots.

[0090] In some other embodiments, in a scenario where multiple target PUCCH resources are used to transmit UCI and repeated transmission is performed within one time slot, the UE can obtain the number of repeated transmissions for each target PUCCH resource, and based on the number of repeated transmissions for each target PUCCH resource, repeatedly transmit the uplink control information UCI to multiple transmission and reception points (TRPs) of the base station within one time slot.

[0091] In some other embodiments, in a scenario where multiple target PUCCH resources are used to transmit UCI and repeated transmission is performed within one time slot, the UE can obtain the number of repeated transmissions for each target PUCCH resource, and based on the number of repeated transmissions for each target PUCCH resource, repeatedly transmit the uplink control information UCI to multiple panels of the base station within one time slot.

[0092] It should be noted that the number of repeated transmissions corresponding to each of the above-mentioned target PUCCH resources may be the same, or all different, or partially the same. This embodiment does not make specific limitations on this.

[0093] For example, the number of the above-mentioned target PUCCH resources is two. The number of repeated transmissions corresponding to the first target PUCCH resource is 2 times, and the number of repeated transmissions corresponding to the second target PUCCH resource is 1 time. In one time slot, in combination with the number of repeated transmissions corresponding to the first target PUCCH resource, the first target PUCCH resource can be used to repeatedly transmit the uplink control information UCI to multiple transmission and reception points (TRPs) of the base station or multiple antenna panels, and in combination with the number of repeated transmissions corresponding to the second target PUCCH resource, the second target PUCCH resource can be used to repeatedly transmit the uplink control information UCI to multiple transmission and reception points (TRPs) of the base station or multiple antenna panels. Among them, the UCI carried by the first target PUCCH resource and the second target PUCCH resource may be the same.

[0094] Among them, the number of retransmission times N is an integer greater than or equal to 1. For example, the number of retransmission times can be 2, 4, 8, etc., and this embodiment does not make specific limitations on this.

[0095] In some embodiments, the above-mentioned number of retransmission times can be configured for the UE through higher-layer signaling; it can also be determined by the UE according to the communication standard.

[0096] Specifically, the UE can receive the higher-layer signaling sent by the UE, where the higher-layer signaling carries the number of retransmission times of the target PUCCH resource. Correspondingly, when the UE determines that UCI needs to be transmitted, the UE retransmits the target PUCCH resource according to the number of retransmission times of the target PUCCH resource.

[0097] Among them, whether the above-mentioned in-slot retransmission method or inter-slot retransmission method is used can be determined based on the indication signaling sent by the base station in some embodiments. The indication signaling includes the retransmission method, and the retransmission method is the in-slot retransmission method or the inter-slot retransmission method. In other embodiments, it can also be determined by the UE based on the retransmission rules in the communication protocol standard adopted by the UE and the base station.

[0098] In some embodiments, the above-mentioned higher-layer signaling can be RRC signaling. In other embodiments, the above-mentioned higher-layer signaling is RRC signaling and MAC CE signaling.

[0099] In the PUCCH resource indication method of the embodiments of the present disclosure, the UE obtains the target PUCCH resource that supports joint transmission of multiple transmission and reception points (TRPs) of the base station, and uses the target PUCCH resource to repeat the transmission of the uplink control information (UCI) to multiple transmission and reception points (TRPs) of the base station within one time slot or between multiple time slots. Thus, the transmission and feedback of the uplink control information are enhanced by using multiple TRPs, and the UCI is retransmitted through the PUCCH resource, which can improve the transmission quality and reliability of the uplink control information, thereby meeting the communication requirements of ultra-high reliable and ultra-low latency communication services.

[0100] As a possible implementation manner, as Figure 3 shown, the PUCCH resource indication method proposed by the present disclosure can be implemented or can be implemented in combination with other methods. This method may include:

[0101] Step 301, obtain the set of target PUCCH resources indicated for the UE that support joint transmission of multiple TRPs of the base station.

[0102] In all embodiments of the present disclosure, the solution can also be applied to the scenario of joint transmission of multiple antenna panels. That is, step 301 is: obtaining a target PUCCH resource set for the UE that indicates support for joint transmission of multiple panels facing the base station.

[0103] In all embodiments of the present disclosure, in the scenario of supporting any joint transmission facing the base station. That is, step 301 is: obtaining a target PUCCH resource set for the UE that indicates support for joint transmission facing the base station.

[0104] In some embodiments of the present disclosure, the target PUCCH resource set for the UE that indicates support for joint transmission of multiple TRPs facing the base station can be determined according to the control signaling sent to the UE. Among them, the control signaling can carry the target PUCCH resource set for the UE that indicates support for joint transmission of multiple TRPs facing the base station.

[0105] In some other embodiments of the present disclosure, the target PUCCH resource set for the UE that indicates support for joint transmission of multiple panels facing the base station can be determined according to the control signaling sent to the UE. Among them, the control signaling can carry the target PUCCH resource set for the UE that indicates support for joint transmission of multiple panels facing the base station.

[0106] In still some other embodiments of the present disclosure, the target PUCCH resource set for the UE that indicates support for joint transmission facing the base station can be determined according to the control signaling sent to the UE. Among them, the control signaling can carry the target PUCCH resource set for the UE that indicates support for joint transmission facing the base station.

[0107] After the UE obtains the control signaling, it can determine the target PUCCH resource set for the UE that indicates support for joint transmission of multiple TRPs facing the base station based on the control signaling. Or, after the UE obtains the control signaling, it can determine the target PUCCH resource set for the UE that indicates support for joint transmission of multiple antenna panels facing the base station based on the control signaling. Or, after the UE obtains the control signaling, it can determine the target PUCCH resource set for the UE that indicates support for joint transmission facing the base station based on the control signaling.

[0108] Among them, the number of the above target PUCCH resource sets can be one or more.

[0109] Step 302, determining a target PUCCH resource from the target PUCCH resource set according to the received downlink control information DCI signaling.

[0110] Among them, the number of the above target PUCCH resources can be one or more.

[0111] Step 303: Use the target PUCCH resource to repeatedly transmit uplink control information (UCI) to multiple transmission and reception points (TRPs) of the base station within one time slot or across multiple time slots.

[0112] Among them, step 303 is the same as step 102 above. For the specific implementation process of step 303, refer to the specific description of step 102 in the above embodiments, which will not be elaborated here. That is, the same as the foregoing embodiments, the repeated transmission in this solution can be applied to the scenario of joint transmission by multiple TRPs, can also be applied to the scenario of joint transmission by multiple panels, and can also be applied to any manner of joint transmission scenario.

[0113] In this embodiment, the UE obtains a set of target PUCCH resources that support joint transmission to multiple TRPs or multiple panels of the base station, and determines the target PUCCH resource from the set of target PUCCH resources according to the downlink control information (DCI) signaling sent by the UE. Use the target PUCCH resource to repeatedly transmit uplink control information (UCI) to multiple transmission and reception points (TRPs) or multiple antenna panels of the base station within one time slot or across multiple time slots. Thereby, using multiple TRPs or multiple panels to enhance the transmission and feedback of uplink control information, and repeatedly transmitting UCI through PUCCH resources can improve the transmission quality and reliability of uplink control information, thus meeting the communication requirements of ultra-high reliability and ultra-low latency communication services.

[0114] As a possible implementation, as Figure 4 shown, the PUCCH resource indication method proposed in this disclosure can be implemented alone or in combination with other methods. The same as the foregoing embodiments, this solution is applied to the scenario of joint transmission by multiple TRPs, can also be applied to the scenario of joint transmission by multiple panels, and can also be applied to any manner of joint transmission scenario. The method may include:

[0115] Step 401: Determine multiple candidate PUCCH resource sets indicated for the UE that support joint transmission to multiple TRPs or multiple panels of the base station according to the received radio resource control (RRC) signaling.

[0116] Step 402: Activate at least one PUCCH resource set in the multiple candidate PUCCH resource sets according to the received media access control element (MAC-CE) signaling, and use the activated PUCCH resource set as the target PUCCH resource set.

[0117] Step 403: Determine the target PUCCH resource from the target PUCCH resource set according to the received downlink control information (DCI) signaling.

[0118] Step 404: Use the target PUCCH resource to repeatedly transmit uplink control information (UCI) to multiple transmission and reception points (TRPs) or multiple panels of the base station within one time slot or across multiple time slots.

[0119] In this embodiment, the UE combines the received RRC signaling, MAC-CE signaling, and DCI signaling to implement the indication of the target PUCCH resource for multiple supported TRPs or multiple panels. Then, the UE uses the target PUCCH resource to repeatedly transmit uplink control information (UCI) to multiple transmission and reception points (TRPs) or multiple panels of the base station within one time slot or across multiple time slots. Thus, by using multiple TRPs or multiple panels to enhance the transmission and feedback of uplink control information, and by repeatedly transmitting UCI through the PUCCH resource, the transmission quality and reliability of uplink control information can be improved, thereby meeting the communication requirements of ultra-reliable and low-latency communication services.

[0120] It can be understood that the step of determining the target PUCCH resource from the target PUCCH resource set according to the DCI signaling in any of the above embodiments can be implemented in various ways in different application scenarios. Examples are as follows:

[0121] In some embodiments, in response to the target PUCCH resource set being one and the target PUCCH resource being one, obtain the resource identifier in the DCI signaling, and determine the target PUCCH resource from the target PUCCH resource set according to the resource identifier.

[0122] In some embodiments, the field content in the PUCCH Resource Indicator (PRI) field in the DCI signaling can be processed, and the resource identifier in the DCI signaling can be determined according to the field content.

[0123] In some other embodiments, in response to the target PUCCH resource set being one and the target PUCCH resource being multiple, obtain multiple resource identifiers in the DCI signaling; determine multiple target PUCCH resources from the target PUCCH resource set according to the multiple resource identifiers.

[0124] In some other embodiments, in response to the target PUCCH resource set being multiple and the target PUCCH resource being multiple, obtain multiple resource identifiers in the DCI signaling; for each resource identifier, determine the target PUCCH resource set to be selected from the multiple target PUCCH resource sets; determine the target PUCCH resource that matches the resource identifier from the target PUCCH resource set to be selected.

[0125] In one embodiment of the present disclosure, in different scenarios, the above-mentioned obtaining of multiple resource identifiers in the DCI signaling can be achieved in various ways, as exemplified below:

[0126] As an example, a resource identifier can be respectively parsed from each resource indication field in the DCI signaling.

[0127] It can be understood that the resource indication field in this example can be obtained by redefining the DCI signaling of the existing communication standard.

[0128] For example, if there are two above-mentioned target PUCCH resources, in order to obtain the respective resource identifiers corresponding to each PUCCH resource from the DCI signaling, the two resource indication fields in the DCI signaling can be respectively parsed to obtain the respective resource identifiers corresponding to the target PUCCH resources.

[0129] As another example, multiple resource identifiers can be parsed from one resource indication field in the DCI signaling.

[0130] It can be understood that the above-mentioned resource indication field in this example can be obtained by expanding the PRI field in the DCI signaling of the existing communication standard.

[0131] For example, if there are two target PUCCH resources, correspondingly, two resource identifiers corresponding to the two PUCCH resources can be parsed from one resource indication field in the DCI.

[0132] Among them, the above-mentioned parsing of multiple resource identifiers from one resource indication field in the DCI signaling can be achieved in various ways, as exemplified below:

[0133] As an example, one resource indication field in the DCI signaling can be parsed to obtain a code point for indicating PUCCH resource information, and then, based on the code point, multiple resource identifiers can be obtained.

[0134] In this embodiment, in order to obtain multiple resource identifiers based on the code point, the UE can pre-store the corresponding relationship between the code point and the resource identifier information.

[0135] As another example, the field content of the resource indication field in the DCI signaling can be obtained, and then, based on the parsing rule, the field content can be parsed to obtain multiple resource identifiers.

[0136] It can be understood that in different application scenarios, the above-mentioned implementation methods for determining the target PUCCH resource set to be selected from multiple target PUCCH resource sets for each resource identifier are different, as exemplified below:

[0137] As an example, in response to the existence of a mapping relationship among a code point, a resource identifier, and a resource set identifier in the UE, for each resource identifier, based on the code point obtained from the DCI signaling and the resource identifier, the resource set identifier that matches the code point and the resource identifier can be obtained from the mapping relationship, and among the multiple target PUCCH resource sets, the PUCCH resource set that matches the resource set identifier is used as the target resource set to be selected.

[0138] As another example, in response to the non-existence of a mapping relationship between the resource identifier and the resource set identifier in the UE, for each resource identifier, based on the preset rules in the UE, the target PUCCH resource set to be selected can be determined from the multiple target PUCCH resource sets.

[0139] For example, there are two PUCCH resource sets where the target PUCCH resources suitable for joint transmission are configured for the UE, and the resource identifier sequence obtained based on the DCI signaling includes two resource identifiers, the first resource identifier 1 and the second resource identifier 2. Assume the preset rule is: the first resource identifier 1 belongs to the target PUCCH resource set with a smaller resource set identifier, and the second resource identifier 2 belongs to the target resource set with a larger resource set identifier. Assume there are two target PUCCH resource sets, the resource set identifier of target PUCCH resource set 1 is 1, and the resource set identifier of target PUCCH resource set 2 is 3. At this time, based on the preset rule, it can be determined that the first resource identifier 1 belongs to target PUCCH resource set 1 with a resource set identifier of 1, and the second resource identifier 2 belongs to target PUCCH resource set 3 with a resource set identifier of 3.

[0140] For another example, there are two PUCCH resource sets where the target PUCCH resources suitable for joint transmission are configured for the UE, and the resource identifier sequence obtained based on the DCI signaling includes two resource identifiers, the first resource identifier 1 and the second resource identifier 2. Assume the preset rule is: the first resource identifier 1 belongs to the target PUCCH resource set with a larger resource set identifier, and the second resource identifier 2 belongs to the target resource set with a smaller resource set identifier. Assume there are two target PUCCH resource sets, the resource set identifier of target PUCCH resource set 1 is 1, and the resource set identifier of target PUCCH resource set 2 is 3. At this time, based on the preset rule, it can be determined that the first resource identifier 1 belongs to target PUCCH resource set 2 with a resource set identifier of 3, and the second resource identifier 2 belongs to target PUCCH resource set 1 with a resource set identifier of 1.

[0141] It should be noted that when the foregoing mentions transmission based on multiple TRPs, usually two TRPs are used as examples. This is because in the related technologies of transmission cooperation based on multiple TRPs currently, it is limited to at most two TRPs. Therefore, in this embodiment, when there are multiple target PUCCH resources in the example, the PUCCH resources are exemplified by two. It can be understood that this embodiment can be applied to the case of transmission based on more TRPs, and there is no limitation in this regard.

[0142] As a possible implementation, as Figure 5 shown, the PUCCH resource indication method proposed by the present disclosure can be implemented alone or in combination with other methods. Similar to the foregoing embodiments, this solution can be applied in the scenario of joint transmission by multiple TRPs, can also be applied in the scenario of joint transmission by multiple panels, and can also be applied in the scenario of joint transmission in any manner. The method may include:

[0143] Step 501, obtain a target PUCCH resource set and a target PUCCH resource combination list that are indicated for the UE and support joint transmission by multiple TRPs or multiple panels facing the base station.

[0144] In some embodiments of the present disclosure, according to the received control signaling, a target PUCCH resource set and a target PUCCH resource combination list that are indicated for the UE and support joint transmission by multiple TRPs facing the base station can be obtained. Among them, the control signaling carries a target PUCCH resource set and a target PUCCH resource combination list that are indicated for the UE and support joint transmission by multiple TRPs facing the base station.

[0145] In other embodiments of the present disclosure, according to the received control signaling, a target PUCCH resource set and a target PUCCH resource combination list that are indicated for the UE and support joint transmission by multiple panels facing the base station can be obtained. Among them, the control signaling carries a target PUCCH resource set and a target PUCCH resource combination list that are indicated for the UE and support joint transmission by multiple panels facing the base station.

[0146] In some embodiments, the above control signaling may be an RRC signaling.

[0147] In one embodiment, the UE can, according to the received RRC signaling, obtain a target PUCCH resource set and a target PUCCH resource combination list that are indicated for the UE and support joint transmission by multiple TRPs facing the base station. In another embodiment, the UE can, according to the received RRC signaling, obtain a target PUCCH resource set and a target PUCCH resource combination list that are indicated for the UE and support joint transmission by multiple panels facing the base station.

[0148] The above-mentioned target PUCCH resource set can be one or more.

[0149] The above-mentioned target PUCCH resource combination list may include resource combination information corresponding to UCI payloads of various sizes.

[0150] Step 502: Determine the code point used to indicate PUCCH resource information according to the received downlink control information DCI signaling.

[0151] Step 503: Obtain the resource identification information corresponding to the code point from the target PUCCH resource combination list.

[0152] It can be understood that in some embodiments, when the above-mentioned target PUCCH resource combination list includes the correspondence between the code point and the resource identification, the above-mentioned resource identification information may include the resource identification and not include the resource set identification. In other embodiments, when the target PUCCH resource combination list includes the correspondence between the code point, the resource identification, and the resource set identification to which the resource identification belongs, the resource identification information may further include the resource identification and the resource set identification to which the resource identification belongs.

[0153] In some embodiments, partial examples of the PUCCH resource combination list including the code point and the combination relationship between two resources are shown in Table 2.

[0154] Table 2 PUCCH Resource Combination List

[0155] PRI codepoint PRI1 PRI2 0 3 NAN 1 5 NAN 2 3 5 … … … … … … N 2 7

[0156] It should be noted that in the above Table 2, the example is given with a maximum of two PUCCH resources. Assume that the first target PUCCH resource and the second target PUCCH resource are used respectively, PRI1 represents the resource identification of the first target PUCCH resource, and the value of PRI2 represents the resource identification of the second target PUCCH resource.

[0157] It can be understood that each element and each corresponding relationship in Table 2 exist independently; these elements and corresponding relationships are listed in the same table by way of example, but it does not mean that all elements and corresponding relationships in the table must exist simultaneously as shown in Table 2. The value of each element and each corresponding relationship therein are independent of the values of any other elements or corresponding relationships in Table 2. Therefore, those skilled in the art can understand that the value of each element and each corresponding relationship in this Table 2 are all independent embodiments.

[0158] In some other embodiments, a partial example of a PUCCH resource combination list including code points, two target PUCCH resource sets, and a combination of two target PUCCH resources is shown in Table 3 above.

[0159] Table 3 PUCCH Resource Correspondence Table

[0160]

[0161] It should be noted that in Table 3 above, the example is given with a maximum of two PUCCH resources and a maximum of two PUCCH resource sets. Among them, PRI1 in Table 3 represents the resource identifier of the first target PUCCH resource, the value of PRI2 represents the resource identifier of the second target PUCCH resource, resource set identifier 1 represents the resource set identifier of the first target PUCCH resource set, and resource set identifier 2 represents the resource set identifier of the second target PUCCH resource set.

[0162] It can be understood that each element and each corresponding relationship in Table 3 exist independently; these elements and corresponding relationships are exemplarily listed in the same table, but it does not mean that all elements and corresponding relationships in the table must exist simultaneously as shown in Table 1. The value of each element and each corresponding relationship is independent of any other element value or corresponding relationship in Table 3. Therefore, those skilled in the art can understand that the value of each element and each corresponding relationship in this Table 3 are all independent embodiments.

[0163] Step 504: Obtain a target PUCCH resource that matches the resource identification information from the target PUCCH resource set.

[0164] Step 505: Use the target PUCCH resource to repeatedly transmit uplink control information UCI to multiple transmission and reception points TRP or multiple panels of the base station within one time slot or between multiple time slots.

[0165] The specific implementation of Step 505 can refer to the relevant descriptions in the above embodiments and will not be elaborated here.

[0166] In this embodiment, the UE obtains a target PUCCH resource set and a target PUCCH resource combination list that indicate to the UE the support for joint transmission by multiple TRPs or multiple panels of the base station; determines, according to the received downlink control information DCI signaling, a code point for indicating PUCCH resource information; obtains, from the target PUCCH resource combination list, resource identification information corresponding to the code point; obtains, from the target PUCCH resource set, a target PUCCH resource that matches the resource identification information, and uses the target PUCCH resource to repeatedly transmit uplink control information UCI to multiple transmission and reception points TRPs or multiple panels of the base station within one time slot or between multiple time slots. Thus, by using multiple TRPs or multiple panels to enhance the transmission and feedback of uplink control information, and by repeatedly transmitting UCI through PUCCH resources, the transmission quality and reliability of uplink control information can be improved, thereby meeting the communication requirements of ultra-high reliable and ultra-low latency communication services.

[0167] As a possible implementation, as Figure 6 shown, the PUCCH resource indication method proposed in the present disclosure can be implemented alone or in combination with other methods. Similar to the foregoing embodiments, this solution can be applied to the scenario of joint transmission by multiple TRPs, can also be applied to the scenario of joint transmission by multiple panels, and can also be applied to any manner of joint transmission scenarios. The method may include:

[0168] Step 601, obtain multiple candidate PUCCH resource sets and multiple candidate PUCCH resource combination lists that indicate to the UE the support for joint transmission by multiple TRPs or multiple panels of the base station.

[0169] In some embodiments of the present disclosure, multiple candidate PUCCH resource sets and multiple candidate PUCCH resource combination lists that indicate to the UE the support for joint transmission by multiple TRPs of the base station can be obtained according to the received control signaling. Among them, the control signaling carries multiple candidate PUCCH resource sets and multiple candidate PUCCH resource combination lists that indicate to the UE the support for joint transmission by multiple TRPs of the base station.

[0170] In other embodiments of the present disclosure, multiple candidate PUCCH resource sets and multiple candidate PUCCH resource combination lists that indicate to the UE the support for joint transmission by multiple panels of the base station can be obtained according to the received control signaling. Among them, the control signaling carries multiple candidate PUCCH resource sets and multiple candidate PUCCH resource combination lists that indicate to the UE the support for joint transmission by multiple panels of the base station.

[0171] In some embodiments, the above control signaling may be an RRC signaling.

[0172] In one embodiment, the UE obtains, according to the received RRC signaling, a plurality of candidate PUCCH resource sets and a plurality of candidate PUCCH resource combination lists indicated for the UE to support joint transmission of multiple TRPs facing the base station. In another embodiment, the UE obtains, according to the received RRC signaling, a plurality of candidate PUCCH resource sets and a plurality of candidate PUCCH resource combination lists indicated for the UE to support joint transmission of multiple panels facing the base station.

[0173] The above PUCCH resource sets may be one or more.

[0174] Among them, different candidate PUCCH resource combination lists correspond to UCI payloads of different sizes.

[0175] Step 602: According to the received Media Access Control Element (MAC-CE) signaling, activate at least one PUCCH resource set among the multiple candidate PUCCH resource sets, and use the activated PUCCH resource set as the target PUCCH resource set, and activate at least one PUCCH resource combination list among the multiple candidate PUCCH resource combination lists, and use the activated PUCCH resource combination list as the target PUCCH resource combination list.

[0176] Step 603: Determine, according to the received Downlink Control Information (DCI) signaling, the code point for indicating the PUCCH resource information.

[0177] Step 604: Obtain, from the target PUCCH resource combination list, the resource identification information corresponding to the code point.

[0178] Step 605: Obtain, from the target PUCCH resource set, the target PUCCH resource that matches the resource identification information.

[0179] Step 606: Use the target PUCCH resource to repeatedly transmit the Uplink Control Information (UCI) facing multiple Transmission and Reception Points (TRPs) or multiple panels of the base station within one time slot or among multiple time slots.

[0180] For the implementation manner of obtaining, from the target PUCCH resource set, the target PUCCH resource that matches the resource identification information in the corresponding embodiments above, in different application scenarios, the implementation manners are different, and examples are as follows: Figure 5 and Figure 6 As an example, in response to the target PUCCH resource set being one, the target PUCCH resource that matches the resource identification information can be directly obtained from the target PUCCH resource set.

[0181] As an example, in response to the target PUCCH resource set being one, the target PUCCH resource that matches the resource identification information can be directly obtained from the target PUCCH resource set.

[0182] Among them, the target PUCCH resource(s) can be one or more.

[0183] As another example, when there are multiple target PUCCH resource sets, in response to the resource identification information including a resource identifier and not including a resource set identifier, according to the resource identifier, a PUCCH resource set to be selected is determined from the multiple target PUCCH resource sets; a target PUCCH resource matching the resource identifier is determined from the PUCCH resource set to be selected.

[0184] Among them, for the specific implementation manner of determining the PUCCH resource set to be selected from the multiple target PUCCH resource sets according to the resource identifier, reference can be made to the relevant descriptions in the foregoing embodiments, which will not be elaborated here.

[0185] Figure 7 It is a schematic diagram of another PUCCH resource indication method proposed according to the present disclosure. Among them, it should be noted that the PUCCH resource indication method of the present disclosure can be executed at a base station.

[0186] Such as Figure 7 As shown, for the PUCCH resource indication method proposed by the present disclosure, this method can be implemented or can be implemented in combination with other methods. Similar to the foregoing embodiments, this solution can be applied to the scenario of joint transmission by multiple TRPs, can also be applied to the scenario of joint transmission by multiple panels, and can also be applied to any joint transmission scenario. This method may include:

[0187] Step 701: Indicate to the UE a target PUCCH resource for supporting joint transmission by multiple transmission and reception points (TRPs) of the base station.

[0188] In all embodiments of the present disclosure, this method can also be applied to the technical solution of joint transmission by multiple antenna panels. That is, step 701 is: Indicate to the UE a target PUCCH resource for supporting joint transmission by multiple antenna panels of the base station.

[0189] In all embodiments of the present disclosure, this method can also be applied to any joint transmission technical solution. That is, step 701 is: Indicate to the UE a target PUCCH resource for supporting joint transmission of the base station.

[0190] In an embodiment of the present disclosure, a control instruction is sent to the UE to indicate to the UE a target PUCCH resource for supporting joint transmission by multiple transmission and reception points (TRPs) of the base station. Among them, the control instruction may carry the target PUCCH resource indicated to the UE for supporting joint transmission by multiple transmission and reception points (TRPs) of the base station.

[0191] In another embodiment of the present disclosure, a control instruction is sent to the UE to indicate to the UE the target PUCCH resource for supporting joint transmission of multiple panels facing the base station. Among them, the control instruction may carry the target PUCCH resource indicated for the UE to support joint transmission of multiple panels facing the base station.

[0192] In yet another embodiment of the present disclosure, a control instruction is sent to the UE to indicate to the UE the target PUCCH resource for supporting joint transmission facing the base station. Among them, the control instruction may carry the target PUCCH resource indicated for the UE to support joint transmission facing the base station.

[0193] Among them, the above control instruction may be a high-layer signaling. In some embodiments, the above high-layer signaling may be an EEC signaling.

[0194] As an exemplary implementation manner, an RRC signaling may be sent to the UE to indicate to the UE, through the RRC signaling, the target PUCCH resource for supporting joint transmission of multiple transmission and reception points (TRPs) facing the base station.

[0195] As another exemplary implementation manner, an RRC signaling may be sent to the UE to indicate to the UE, through the RRC signaling, the target PUCCH resource for supporting joint transmission of multiple panels facing the base station.

[0196] As yet another exemplary implementation manner, an RRC signaling may be sent to the UE to indicate to the UE, through the RRC signaling, the target PUCCH resource for supporting joint transmission facing the base station.

[0197] Among them, the above target PUCCH resource may be one or more, and this embodiment does not make specific limitations on this. In practical applications, the number of target PUCCH resources may be indicated according to actual requirements.

[0198] In some embodiments, when the target PUCCH resource is one, in order to enable multiple transmissions, the above target PUCCH resource may correspond to multiple different beams. For example, the above target PUCCH resource may correspond to two different beams. That is, in one embodiment, in order to implement multi-TRP transmission, the one target PUCCH resource may correspond to multiple different beams. In order to support joint transmission of multiple antenna panels, the one target PUCCH resource may correspond to multiple different beams.

[0199] In other embodiments, when the target PUCCH resources are multiple, the above multiple target PUCCH resources may correspond to one beam, or multiple different beams, and this embodiment does not make specific limitations on this.

[0200] Step 702: Receive the uplink control information UCI sent by the UE, where the UCI is repetitively transmitted to multiple TRPs of the base station within one time slot or among multiple time slots by using the target PUCCH resource.

[0201] In all embodiments of the present disclosure, this solution can also be applied to the joint transmission of multiple antenna panels. That is, step 702 is: Receive the uplink control information UCI sent by the UE, where the UCI is repetitively transmitted to multiple panels of the base station within one time slot or among multiple time slots by using the target PUCCH resource.

[0202] In all embodiments of the present disclosure, this solution can also be applied to any transmission scheme of joint transmission. That is, step 702 is: Receive the uplink control information UCI sent by the UE, where the UCI is repetitively transmitted to the joint transmission of the base station within one time slot or among multiple time slots by using the target PUCCH resource.

[0203] In the PUCCH resource indication method according to the embodiments of the present disclosure, the base station indicates to the UE the target PUCCH resource that supports joint transmission to multiple transmission and reception points (TRPs) of the base station, and receives the uplink control information UCI repetitively transmitted by the UE to multiple TRPs of the base station within one time slot or among multiple time slots by using the target PUCCH resource. Thus, the base station configures for the UE the target PUCCH resource suitable for joint transmission. Correspondingly, the base station receives the uplink control information UCI repetitively transmitted by the UE to multiple TRPs of the base station within one time slot or among multiple time slots by using the target PUCCH resource, thereby realizing the enhancement of the transmission and feedback of the uplink control information by using multiple TRPs, and repetitively transmitting the UCI through the PUCCH resource, which can improve the transmission quality and reliability of the uplink control information, so as to meet the communication requirements of ultra-high reliable and ultra-low latency communication services.

[0204] As a possible implementation manner, as Figure 8 shown, the PUCCH resource indication method proposed in the present disclosure can be implemented alone or in combination with other methods. The same as the foregoing embodiments, this solution is applied to the scenario of joint transmission of multiple TRPs, and can also be applied to the scenario of joint transmission of multiple panels, and can also be applied to the scenario of joint transmission in any manner. The method may include:

[0205] Step 801: Indicate to the UE a set of target PUCCH resources for supporting joint transmission to multiple TRPs of the base station.

[0206] In all embodiments of the present disclosure, this solution can also be applied to scenarios of joint transmission by multiple antenna panels. That is, step 801 is: indicating to the UE a target PUCCH resource set for supporting joint transmission by multiple panels facing the base station.

[0207] In all embodiments of the present disclosure, this solution can also be applied to scenarios of joint transmission in any manner. That is, step 801 is: indicating to the UE a target PUCCH resource set for supporting joint transmission facing the base station.

[0208] In one embodiment of the present disclosure, the base station can indicate to the UE a target PUCCH resource set for supporting joint transmission by multiple TRPs facing the base station by sending control signaling to the UE. In another embodiment of the present disclosure, the base station can indicate to the UE a target PUCCH resource set for supporting joint transmission by multiple panels facing the base station by sending control signaling to the UE. In yet another embodiment of the present disclosure, the base station can indicate to the UE a target PUCCH resource set for supporting joint transmission facing the base station by sending control signaling to the UE.

[0209] Among them, the above control signaling can be high-layer signaling.

[0210] As an example, the above high-layer signaling can be RRC signaling.

[0211] In one embodiment, the base station can send RRC signaling to the UE, where the RRC signaling carries a target PUCCH resource set indicated for the UE that can support joint transmission by multiple TRPs facing the base station. In another embodiment, the base station can send RRC signaling to the UE, where the RRC signaling carries a target PUCCH resource set indicated for the UE that can support joint transmission by multiple panels facing the base station. In yet another embodiment, the base station can send RRC signaling to the UE, where the RRC signaling carries a target PUCCH resource set indicated for the UE that can support joint transmission facing the base station.

[0212] Step 802, sending downlink control information DCI signaling to the UE, where the DCI signaling is used to indicate to the UE to determine a target PUCCH resource from the target PUCCH resource set.

[0213] Step 803, receiving uplink control information UCI sent by the UE, where the UCI is repeatedly sent to multiple TRPs facing the base station within one time slot or between multiple time slots by using the target PUCCH resource.

[0214] In all embodiments of the present disclosure, this solution can also be applied to joint transmission of multi-antenna panels. That is, step 803 is: receiving uplink control information (UCI) sent by a UE, where the UCI is repeatedly sent to multiple panels of a base station within one time slot or among multiple time slots by using a target PUCCH resource.

[0215] In all embodiments of the present disclosure, this solution can also be applied to any transmission scheme of joint transmission. That is, step 803 is: receiving uplink control information (UCI) sent by a UE, where the UCI is repeatedly sent to joint transmission of a base station within one time slot or among multiple time slots by using a target PUCCH resource.

[0216] In this embodiment, the base station indicates a set of target PUCCH resources for the UE to support joint transmission to multiple transmission and reception points (TRPs) or multiple panels of the base station, and sends downlink control information (DCI) signaling to the UE, so that the UE determines a target PUCCH resource from the set of target PUCCH resources through the DCI signaling, and receives the uplink control information (UCI) repeatedly sent by the UE to multiple transmission and reception points (TRPs) or multiple panels of the base station within one time slot or among multiple time slots by using the target PUCCH resource. Thus, the base station configures a target PUCCH resource suitable for joint transmission for the UE. Correspondingly, the base station receives the uplink control information (UCI) repeatedly sent by the UE to multiple transmission and reception points (TRPs) or multiple panels of the base station within one time slot or among multiple time slots by using the target PUCCH resource, thereby realizing enhancing the transmission and feedback of uplink control information by using multiple TRPs or multiple panels, and repeatedly sending the UCI through the PUCCH resource, which can improve the transmission quality and reliability of the uplink control information, so as to meet the communication requirements of ultra-high reliable and ultra-low latency communication services.

[0217] As a possible implementation manner, as Figure 9 shown, the PUCCH resource indication method proposed in the present disclosure can be implemented alone or in combination with other methods.
