Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, in particular to a PUCCH retransmission determination and configuration method and device, a storage medium, user equipment and network side equipment. BACKGROUND

[0002] In the discussion of communication protocol version 17 (Release 17, R17) coverage enhancement, the physical uplink control channel (Physical Uplink Control Channel, PUCCH) needs to increase the number of retransmissions to improve the coverage capability.

[0003] When the user equipment (User Equipment, UE) transmits the PUCCH, it can be divided into the following two cases: Case-1: the UE has no dedicated PUCCH resource configuration information; Case-2: the UE has dedicated PUCCH resource configuration information. Among them, in case-1, the UE obtains the related configuration information of the PUCCH in the system information block (System Information Block, SIB) 1. After the UE determines the index, it can know a series of configuration information corresponding to the PUCCH. The row index is determined according to the serial number of the first control channel element (Control Channel Element, CCE) of the PDCCH and the PUCCH resource indication information in the downlink control information (Downlink Control Information, DCI). Among them, the PUCCH of Case-1 has no retransmission number, that is, it is transmitted only once. In Case-2, the number of retransmissions is mainly configured through the high layer signaling radio resource control (Radio Resource Control, RRC) signaling, and must be configured through the dedicated PUCCH resource.

[0004] However, the current PUCCH retransmission number configuration method is semi-static, but the uplink transmission condition may change in the semi-static period, and the retransmission number is no longer suitable for the current transmission condition, resulting in the transmission of uplink data being affected.

[0026] As described in the background, the current configuration mode of the PUCCH retransmission number is semi-static, however, in the semi-static period, the uplink transmission condition may change, the retransmission number is no longer suitable for the current transmission condition, resulting in the transmission of uplink data being affected.

[0027] In the technical solution of the present application, by indicating the correspondence between the PUCCH retransmission number and the PUCCH resource to the user equipment in the downlink signaling, the user equipment can determine the retransmission number according to the PUCCH resource actually used in the PUCCH transmission, or determine the retransmission number according to the retransmission number of the associated PDSCH at each PUCCH transmission, or determine the retransmission number according to the retransmission number of the PUCCH with the closest transmission occasion to the transmission occasion of the PUCCH to be transmitted at each PUCCH transmission, thereby dynamically determining the PUCCH retransmission number, so that the PUCCH retransmission number can be suitable for the current transmission condition, ensuring the normal transmission of the PUCCH and the normal interaction between the user equipment and the network side.

[0028] The technical solution of the present application can be applied to the 5G (5 Generation) communication system, and can also be applied to the 4G, 3G communication system, and can also be applied to future new communication systems, such as 6G, 7G, etc.

[0029] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0030] Figure 1 is a flowchart of a PUCCH retransmission determination method according to an embodiment of the present application.

[0031] The PUCCH retransmission determination method can be used on the user equipment (User Equipment, UE) side, that is, can be executed by the user equipment Figure 1 each step of the method shown.

[0032] Specifically, the PUCCH retransmission determination method can include the following steps:

[0033] Step S101: receiving downlink signaling, the downlink signaling including the correspondence between the PUCCH retransmission number and the PUCCH resource;

[0034] Step S102: determining the retransmission number of the to-be-sent PUCCH according to the PUCCH resource used by the to-be-sent PUCCH and the correspondence, or determining the retransmission number of the to-be-sent PUCCH according to the retransmission number of the PDSCH associated with the to-be-sent PUCCH, or determining the retransmission number of the to-be-sent PUCCH according to the retransmission number of the already-sent PUCCH closest in transmission occasion to the transmission occasion of the to-be-sent PUCCH.

[0035] It should be noted that the serial numbers of the steps in the embodiment do not represent the limitation on the execution order of the steps.

[0036] The retransmission number referred to in the embodiment of the application refers to the number of repeated transmissions.

[0037] All the embodiments given in the application can also be applied to repeated transmission of some PUCCHs carrying proprietary information. The proprietary information can include at least one of the following information: scheduling request (SR), beam failure recovery scheduling request (BFR-SR), CSI, beam failure recovery (BFR) information, and HARQ-ACK.

[0038] In the embodiment, the network side can pre-configure the correspondence between the PUCCH retransmission number and the PUCCH resource, and notify the UE through downlink signaling. The UE can obtain the correspondence between the PUCCH retransmission number and the PUCCH resource through the downlink signaling. The downlink signaling can be selected from RRC, MAC CE and DCI, or other any implementable downlink signaling, and the embodiment of the application does not limit this.

[0039] In specific implementation, the correspondence between the PUCCH retransmission number and the PUCCH resource can be the correspondence between the PUCCH retransmission number and the resource index of the PUCCH resource, or the correspondence between the PUCCH retransmission number and the time domain length (such as symbol duration) occupied by the PUCCH resource, and the like, which will not be repeated here.

[0040] Further in the specific implementation of step S102, when sending the PUCCH, the UE can find the retransmission number corresponding to the resource matched with the PUCCH resource used by the to-be-sent PUCCH in the above correspondence, and transmit the PUCCH based on the found retransmission number.

[0041] In one variation of the present application, the retransmission number of the PUCCH to be sent is determined according to the retransmission number of a physical downlink shared channel (PDSCH) associated with the PUCCH to be sent. Here, the association can mean that the HARQ-ACK information of the PDSCH is carried by the PUCCH.

[0042] In the present embodiment, the retransmission number of the PUCCH is associated with the retransmission number of the PDSCH associated with the PUCCH. Since the performance requirements for coverage of the PDSCH and the PUCCH can be different, the retransmission number of the PUCCH can not be consistent with the retransmission number of the PDSCH, but there is a correlation in the numerical value. That is, the retransmission number of the PUCCH can be calculated or derived from the retransmission number of the PDSCH.

[0043] Specifically, the retransmission number of the PUCCH can be uniquely determined by the retransmission number of the PDSCH. The specific calculation relationship can be pre-configured by the base station through downlink signaling, or can be determined by a pre-defined manner, for example, the conversion relationship between the retransmission number of the PDSCH and the retransmission number of the PUCCH is pre-defined by the communication standard protocol.

[0044] For example, if the retransmission number of the PDSCH is indicated as 2 times in the DCI, the PUCCH can be 2+X times, or 2X times, or the same as the retransmission number of the PUCCH, X being a positive integer greater than or equal to 1. The specific value of X can be pre-configured by the base station through downlink signaling, or can be determined by a pre-defined manner by the standard protocol.

[0045] It should be noted that the calculation of the retransmission number of the PUCCH from the retransmission number of the PDSCH can also be any other implementable more complex calculation formula, and the present embodiment does not limit this.

[0046] In another variation of the present application, the retransmission number of the PUCCH to be sent is determined according to at least the retransmission number of a PUCCH that has been sent and whose transmission occasion is closest to the transmission occasion of the PUCCH to be sent. That is, the retransmission number of the PUCCH to be sent can be determined as the retransmission number of the PUCCH that has been sent and whose transmission occasion is closest to the transmission occasion of the PUCCH to be sent.

[0047] The embodiment of the present application can dynamically determine the PUCCH retransmission times, so that the PUCCH retransmission times can adapt to the current transmission condition, and ensure the normal transmission of the PUCCH and the normal interaction between the user equipment and the network side.

[0048] In one non-limiting embodiment of the present application, the downlink signaling comprises the correspondence between the PUCCH retransmission times and the time domain length occupied by the PUCCH resource.

[0049] Table 1

[0050] Number of symbols Number of retransmissions 4 2 5 4 。。。 。。。 14 32

[0051] As shown in Table 1, when the time domain length occupied by the PUCCH resource is 4 symbols, the PUCCH retransmission times is 2, when the time domain length occupied by the PUCCH resource is 5 symbols, the PUCCH retransmission times is 4, and so on, when the time domain length occupied by the PUCCH resource is 14 symbols, the PUCCH retransmission times is 32. The above correspondence can be sent to the UE by the base station through RRC signaling, or be predefined by the communication standard protocol.

[0052] Further, Figure 1 The step S102 can comprise the following steps: determining the PUCCH retransmission times corresponding to the time domain length occupied by the PUCCH resource used by the PUCCH to be transmitted according to the correspondence, as the retransmission times of the PUCCH to be transmitted. For example, the PUCCH resource used by the PUCCH to be transmitted is 5 symbols, and the retransmission times of the PUCCH to be transmitted can be determined as 4 by looking up Table 1.

[0053] In another non-limiting embodiment of the present application, the downlink signaling comprises the correspondence between the PUCCH retransmission times and the time domain length occupied by the PUCCH resource of each format. As shown in Table 2, the correspondence between the number of symbols of the PUCCH of Format 3 and the retransmission times.

[0054] Table 2

[0055] Number of symbols for Format 3 PUCCH Number of retransmissions 4 2 5 4 。。。 。。。 14 32

[0056] The correspondence can be sent to the UE by the base station through RRC signaling, or be predefined by a communication standard protocol.

[0057] Further, Figure 1 The step S102 can include the following steps: determining the PUCCH retransmission number corresponding to the time domain length in the format of the PUCCH resource used by the PUCCH to be sent, as the retransmission number of the PUCCH to be sent. For example, the format of the PUCCH to be sent is Format 3, and the PUCCH resource used is 5 symbols. By looking up the above table 2, it can be determined that the retransmission number of the PUCCH to be sent is 4.

[0058] In one embodiment of the present application, the downlink signaling includes RRC signaling, and the PUCCH resource corresponding retransmission number is updated or indicated by combining RRC and MAC CE. The PUCCH resource can be identified by a PUCCH resource index (PUCCH Resource Index, PRI). The RRC signaling includes a plurality of groups of PUCCH retransmission numbers and PUCCH resource indexes corresponding relationship, and the MAC CE includes a group identifier. Figure 1 The step S102 can include the following steps: according to the correspondence, looking up a plurality of groups of PUCCH retransmission numbers corresponding to the resource index of the PUCCH resource used by the PUCCH to be sent; and determining the PUCCH retransmission number indicated by the group identifier carried in the MAC CE in the plurality of groups of PUCCH retransmission numbers looked up, as the retransmission number of the PUCCH to be sent.

[0059] The embodiment of the present application updates the PUCCH resource corresponding retransmission number by combining RRC and MAC CE. Specifically, the base station configures a corresponding plurality of groups of retransmission numbers for each PUCCH resource index (PUCCH Resource Index, PRI) through RRC, each group of retransmission numbers has a group identifier, and then updates which group is applied through MAC CE. Each group of retransmission numbers can uniquely correspond to one retransmission number.

[0060] In another embodiment of the present application, the downlink signaling includes resource configuration signaling, the resource configuration signaling includes a plurality of groups of PUCCH retransmission numbers and PUCCH resource corresponding relationship, and the DCI includes PUCCH resource retransmission number indication information. Optionally, the base station can activate or deactivate the PUCCH resource retransmission number through MAC CE. Figure 1 The step S102 can include the following steps: determining the PUCCH retransmission number corresponding to the PUCCH resource index carried in the DCI in the plurality of corresponding relationships, as the retransmission number of the PUCCH to be sent.

[0061] In another specific embodiment of the present application, when the base station configures the PUCCH resources for the UE through downlink signaling, it also configures the corresponding retransmission number for each resource, i.e. the correspondence between the PUCCH retransmission number and the PUCCH resource. Thus, when the base station indicates the specific PRI to the UE through the DCI, it also implicitly indicates the retransmission number to the UE.

[0062] In a non-limiting embodiment of the present application, the PUCCH to be transmitted is a periodic PUCCH or a semi-persistent PUCCH. In this case, a transmitted PUCCH that is closest in transmission timing to the PUCCH to be transmitted and has the same format is determined, and the number of retransmissions of the transmitted PUCCH is taken as the number of retransmissions of the PUCCH to be transmitted; or a transmitted aperiodic PUCCH that is closest in transmission timing to the PUCCH to be transmitted and has the same format is determined, and the number of retransmissions of the transmitted PUCCH is taken as the number of retransmissions of the PUCCH to be transmitted; or a transmitted PUCCH that carries HARQ-ACK information and is closest in transmission timing to the PUCCH to be transmitted and has the same format is determined, and the number of retransmissions of the transmitted PUCCH is taken as the number of retransmissions of the PUCCH to be transmitted; or a transmitted PUCCH that has more than one retransmission and is closest in transmission timing to the PUCCH to be transmitted and has the same format is determined, and the number of retransmissions of the transmitted PUCCH is taken as the number of retransmissions of the PUCCH to be transmitted; or a transmitted PUCCH that has the same occupied time domain length and is closest in transmission timing to the PUCCH to be transmitted and has the same format is determined, and the number of retransmissions of the transmitted PUCCH is taken as the number of retransmissions of the PUCCH to be transmitted; or a transmitted aperiodic PUCCH that has the same occupied time domain length and is closest in transmission timing to the PUCCH to be transmitted and has the same format is determined, and the number of retransmissions of the transmitted aperiodic PUCCH is taken as the number of retransmissions of the PUCCH to be transmitted; or a transmitted PUCCH that carries HARQ-ACK information and has the same occupied time domain length and is closest in transmission timing to the PUCCH to be transmitted and has the same format is determined, and the number of retransmissions of the transmitted aperiodic PUCCH is taken as the number of retransmissions of the PUCCH to be transmitted; or a transmitted PUCCH that has more than one retransmission and has the same occupied time domain length and is closest in transmission timing to the PUCCH to be transmitted and has the same format is determined, and the number of retransmissions of the transmitted aperiodic PUCCH is taken as the number of retransmissions of the PUCCH to be transmitted. Optionally, the time difference between the transmission time of the transmitted PUCCH and the transmission time of the PUCCH to be transmitted is less than a preset threshold. The preset threshold can be configured by downlink signaling or predefined by a communication standard protocol.

[0063] Specifically, the format of the periodic or semi-persistent PUCCH is predefined as x, and the number of retransmissions is only referred to the number of retransmissions of a PUCCH that carries HARQ-ACK information and has the same format and is closest in transmission timing.

[0064] Alternatively, the format of the periodic or semi-persistent PUCCH is predefined as x, and the number of retransmissions is only referred to the number of retransmissions of the most recent PUCCH with the same format.

[0065] Alternatively, the format of the periodic or semi-persistent PUCCH is predefined as x, and the number of retransmissions is only referred to the number of retransmissions of the most recent PUCCH with the same format and the number of retransmissions is greater than 1.

[0066] Alternatively, the format of the periodic or semi-persistent PUCCH is predefined as x, and the number of retransmissions is only referred to the number of retransmissions of the most recent PUCCH with the same format and the number of retransmissions is greater than 1.

[0067] Alternatively, the format of the periodic or semi-persistent PUCCH is predefined as x, and the number of retransmissions is only referred to the number of retransmissions of the most recent PUCCH with the same format and the number of retransmissions is greater than 1.

[0068] Alternatively, the format of the periodic or semi-persistent PUCCH is predefined as x, and the number of retransmissions is only referred to the number of retransmissions of the most recent PUCCH with the same format and the number of retransmissions is greater than 1. Further, if there is no transmitted PUCCH satisfying the above requirement, the UE can transmit the periodic or semi-persistent PUCCH with a predefined number of retransmissions. For example, the retransmission can be performed with the maximum value of the allowed number of retransmissions, or the default number of retransmissions is 1.

[0069] As a variation, the format of the periodic or semi-persistent PUCCH is predefined as x and the number of symbols is y, if the number of symbols of the most recent transmitted PUCCH satisfying the requirement is z and the number of retransmissions is N. Then, the number of retransmissions M of the periodic or semi-persistent PUCCH is determined jointly by y, z, and N. For example, the number of retransmissions M is calculated by the following formula: M = N x round(z / y), or M = N x ceil(z / y), or M = N x floor(z / y), where the round() function means rounding a floating-point number to the nearest integer, the ceil() function means rounding up to the nearest integer, and the floor() function means rounding down to the nearest integer.

[0070] In a non-restrictive embodiment of the present application, the PUCCH to be transmitted is a periodic or semi-persistent PUCCH, and the number of retransmissions corresponding to the PUCCH resource or PUCCH format can be indicated by a MAC CE. Specifically, the MAC CE can include at least one of the following indication information: the format of the PUCCH resource, the index of the PUCCH resource, and the number of retransmissions of the PUCCH resource. In this case, the number of retransmissions indicated in the MAC CE is taken as the number of retransmissions of the PUCCH resource to be transmitted; or the number of retransmissions indicated in the MAC CE is taken as the number of retransmissions corresponding to the indicated PUCCH format, i.e., the PUCCH resources with the same PUCCH format will all use the number of retransmissions indicated in the MAC CE for repeated transmission.

[0071] In the present embodiment, the number of retransmissions of the periodic or semi-persistent PUCCH is updated / indicated by a MAC CE. Specifically, the MAC CE can be used to update / indicate the number of retransmissions of a PUCCH of a certain format, or can be used to update / indicate the number of retransmissions of a certain PUCCH resource (i.e., PUCCH resource index).

[0072] Please refer to Figure 2 The present application also discloses a PUCCH retransmission configuration method. The PUCCH retransmission configuration method can be used in a network-side device, such as a base station.

[0073] Specifically, the PUCCH retransmission configuration method can include the following steps:

[0074] Step S201: determining the correspondence between the number of PUCCH retransmissions and the PUCCH resource;

[0075] Step S202: carrying the correspondence in downlink signaling for transmission, so that the user equipment determines the number of retransmissions of the PUCCH to be transmitted according to the PUCCH resource used by the PUCCH to be transmitted and the correspondence, or determines the number of retransmissions of the PUCCH to be transmitted according to the number of retransmissions of the PDSCH associated with the PUCCH to be transmitted, or determines the number of retransmissions of the PUCCH to be transmitted according to the number of retransmissions of the PUCCH that has been transmitted and whose transmission occasion is closest to the transmission occasion of the PUCCH to be transmitted.

[0076] In the present embodiment, the base station can pre-configure the correspondence between the number of PUCCH retransmissions and the PUCCH resource, and dynamically indicate the number of retransmissions by notifying the UE through downlink signaling.
