Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a communication method, device and storage medium for PUCCH. Background Art

[0002] With the development of communication technology, in order to ensure coverage, beam-based transmission and reception are required. When a network device (such as a base station) has multiple transmission reception points (TRP), multiple TRPs (Multi-TRP) / multi-panels (PANEL) can be used to provide services for terminals. The application of multiple TRPs / PANELs in network devices is mainly to improve the coverage of the cell edge, provide a more balanced service quality in the service area, and use different methods to collaborate to transmit data between multiple TRPs / PANELs. From the perspective of network morphology, network deployment with a large number of distributed access points plus baseband centralized processing will be more conducive to providing a balanced user experience rate and significantly reduce the delay and signaling overhead caused by handover. By utilizing the collaboration between multiple TRPs / PANELs and transmitting / receiving channels from multiple beams at multiple angles, various shielding / blocking effects can be better overcome, ensuring the robustness of link connections, and it is suitable for ultra-reliable low latency communication (URLLC) services to improve transmission quality and meet reliability requirements.

[0003] In the R16 research phase, based on the application of multi-point coordinated transmission technology between downlink multiple TRPs / PANELs, the physical downlink shared channel (PDSCH) was enhanced. Since data transmission includes scheduling feedback of uplink and downlink channels, in the URLLC research, only enhancing the downlink data channel cannot guarantee service performance. Therefore, in the R17 research, the downlink control channel (PDCCH) and uplink control channel (PUCCH) and uplink shared channel (PUSCH) will continue to be enhanced.

[0004] The uplink enhancement scheme based on multi-TRP is mainly based on the PUCCH / PUSCH repeated transmission scheme. In R15 / 16, considering the uplink coverage problem, a mechanism for repetition transmission in multiple time slots was introduced for long PUCCH (corresponding to PUCCH format 1 / 3 / 4). Different PUCCH resources are transmitted according to the same transmission symbol length in different transmission opportunities of each slot. The uplink enhancement scheme based on multi-TRP in R17 is mainly based on the PUSCH repeated transmission scheme of R16. In the R17 multi-TRP enhancement, PUCCH supports collaborative transmission of the same transport block (Transport Block, TB) to different TRP directions at different transmission opportunities (Transmission Occasion, TO), so as to further apply spatial multiplexing transmission to improve transmission reliability.

[0005] For PUCCH channel transmission, there can be inter-slot repetition methods (i.e. Scheme 1) and intra-slot repetition methods. The intra-slot transmission methods include the intra-slot frequency hopping-based repetition transmission scheme (i.e. Scheme 2) and the intra-slot-based repetition transmission scheme (i.e. Scheme 3). However, in the R17 multi-TRP-based PUCCH enhancement, the repetition enhancement schemes sent for different TRPs, including the intra-slot (including scheme 2 & scheme 3) and inter-slot (scheme 1) transmission schemes, cannot meet the various scenario requirements under multi-TRP transmission, so it is necessary to provide possible enhancement schemes to enhance transmission reliability.

Figure 2As shown, different PUCCH resources are transmitted with the same transmission symbol length in different transmission opportunities in each slot. A PUCCH repeated transmission can only use one PUCCH resource, which is configured with a beam direction, namely spatial information (spatialRelationInfo), and is applied to all transmission opportunities. The network configures the corresponding number of repeated transmissions supported by the PUCCH format (PUCCH format) through the Radio Resource Control (RRC) high-level signaling. The indicated range is defined as {1,2,4,8}. Different PUCCH resources may correspond to different PUCCH formats.

[0120] In the R17 PUCCH enhancement based on multi-TRP, PUCCH supports collaborative transmission of the same transport block TB in different TOs to different TRP directions, so as to further apply spatial multiplexing transmission to improve transmission reliability. For PUCCH channel transmission, the possible solutions for R17 enhancement are:

[0121] Scheme 1: Inter-slot repetition method (i.e. Scheme 1)

[0122] The same TDM repetitive transmission method as R15 / 16 realizes time-sharing collaborative transmission in multiple time slots in multiple beam directions facing multiple TRPs. The number of repeated transmission time slots is the number of time slots occupied by the configured transmission. The resource allocation of each time slot is the same, that is, the repeated version of PUCCH is sent on the same time-frequency resources in each time slot.

[0123] Solution 2: Intra-slot repetition, which is not supported by the existing protocol, is the time-sharing joint transmission of multiple beam directions facing multiple TRPs in one time slot. However, there are two repetition transmission schemes for intra-slot repetition:

[0124] A: A transmission scheme based on frequency hopping within a time slot (i.e., Scheme 2), that is, within a PUCCH resource, different symbol groups corresponding to the two hops within the time slot are sent in different beam directions; the frequency hopping function (intra-time slot frequency hopping FH) can be turned on or off. Figure 3 A schematic diagram of a transmission scheme based on frequency hopping repetitive transmission within a time slot is shown. Figure 3As shown, the PUCCH resource occupies N symbols, the first frequency hopping resource block occupies floor(N / 2) time domain symbols in the time slot, mapped in the beam direction corresponding to TRP1 for transmission, and the second frequency hopping resource block occupies N-floor(N / 2) time domain symbols, mapped in the beam direction corresponding to TRP2 for transmission. Among them, beam 1 and beam 2 are mapped on different frequency hopping resources in the same time slot. When frequency hopping is turned on in the time slot, the starting frequency positions of different frequency hopping resources in the same time slot differ by the frequency deviation configured by the network. When frequency hopping is turned off in the time slot, the starting frequencies of different frequency hopping resources in the same time slot are the same.

[0125] Among them, the frequency hopping-based repeated transmission scheme within the time slot in the embodiment of the present disclosure can also be understood as a beam hopping-based repeated transmission scheme within the time slot. Therefore, the frequency hopping-based repeated transmission scheme within the time slot and the beam hopping-based repeated transmission scheme within the time slot in the embodiment of the present disclosure are sometimes used interchangeably, but those skilled in the art should understand the consistency of their meanings.

[0126] B: Sub-slot-based transmission scheme within a time slot (i.e., Scheme 3): that is, PUCCH is repeatedly transmitted in units of sub-slots within a time slot, which is defined as multiple transmissions in a time slot (i.e., the number of repeated transmissions K>=2), and each repeated transmission TO is sent in different beam directions. Figure 4 A schematic diagram of a sub-slot based repetitive transmission scheme within a time slot is shown. Figure 4 As shown, the PUCCH resource occupies N symbols, the first sub-time slot resource block in the time slot occupies floor (N / 2) time domain symbols, mapped to the beam direction corresponding to TRP1 for transmission, and the second sub-time slot resource block occupies N-floor (N / 2) time domain symbols, mapped to the beam direction corresponding to TRP2 for transmission. Among them, beam 1 and beam 2 are mapped to different sub-time slot resources in the same time slot.

[0127] Among them, there are multiple mapping schemes for the mapping relationship between the beam transmission direction of the PUCCH sent by the terminal for different TRPs and different transmission opportunities. The following three schemes can be used. The high-level signaling will configure the beam mapping scheme used for this PUCCH transmission:

[0128] Solution a: Periodic mapping. Two beam directions are cyclically mapped to multiple configured transmission opportunities in sequence. For example, when there are four transmissions, the beam direction mapping pattern is #1#2#1#2.

[0129] Solution b: Continuous mapping. Two beam directions are continuously and cyclically mapped to multiple configured transmission opportunities. For example, when there are 4 transmissions, the pattern of beam direction mapping is #1#1#2#2. For more than 4 transmissions, the pattern is repeated. For example, for 8 transmissions, the pattern of TCI state mapping is #1#1#2#2#1#1#2#2.

[0130] Solution c: Half-and-half mapping. Two beam directions are continuously mapped to multiple configured transmission opportunities. For example, when there are 8 transmissions, the beam direction mapping pattern is #1#1#1#1#2#2#2#2.

[0131] Based on the above description, it can be known that in the PUCCH enhancement based on multi-TRP in R17, the enhancement schemes for sending different TRPs mainly include the transmission schemes within the time slot (including scheme 2 & scheme 3) and between time slots (scheme 1). Moreover, most of the parameters of the different repeated transmission schemes involved above are semi-static parameters configured by RRC. However, different repeated transmission schemes can be targeted at different scenarios and service requirements. Then when the specific scenarios and services change, since most of the parameters are semi-static parameters configured by RRC, the configuration cannot be changed dynamically in time, and network reconfiguration is required to solve it, which will reduce the scheduling flexibility and efficiency of the system.

[0132] In view of this, an embodiment of the present disclosure provides a communication method for PUCCH. In the communication method for PUCCH, when a terminal collaboratively sends PUCCH in multiple TRP directions, it supports dynamic switching between different repetition transmission schemes to improve system scheduling flexibility and efficiency.

[0133] Figure 5 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Figure 5 As shown, the communication method for PUCCH is used in a network device and includes the following steps.

[0134] In step S11, in response to determining that the terminal sends PUCCH in collaboration in multiple TRP directions, indication information is sent.

[0135] Among them, in the embodiment of the present disclosure, the indication information sent by the network device is used to instruct the terminal to dynamically switch the repetition transmission scheme to collaboratively repeat the transmission of PUCCH in multiple TRP directions.

[0136] Furthermore, the repetitive transmission scheme includes an inter-time slot repetitive transmission scheme, a beam hopping-based repetitive transmission scheme within a time slot, and a sub-time slot-based repetitive transmission scheme within a time slot.

[0137] In the disclosed embodiment, when the network device determines that the terminal transmits PUCCH in a collaborative manner in multiple TRP directions, the configuration and dynamic switching between different PUCCH transmission schemes are indicated by indication information, so that the terminal can transmit PUCCH in a collaborative manner in different TRP directions according to different transmission schemes. For example, when the number of beam direction information (spatial relation info) of the corresponding PUCCH resource activated by the Media Access Control (MAC)-Control Element (CE) is 2, corresponding to multi-TRP transmission, PUCCH is transmitted in a collaborative manner in different TRP directions according to different transmission schemes.

[0138] In one implementation provided by the embodiment of the present disclosure, the network device can implement switching of different repetitive transmission schemes by configuring sub-time slot transmission configuration parameters. That is, the network device can indicate the sub-time slot resource information occupied by the collaborative repetitive transmission of PUCCH in multiple TRP directions by sending sub-time slot transmission configuration parameters.

[0139] Figure 6 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Figure 6 As shown, the communication method for PUCCH is used in a network device and includes the following steps.

[0140] In step S21, in response to determining that the terminal transmits PUCCH in collaboration in multiple TRP directions, sub-timeslot transmission configuration parameters are sent.

[0141] In the disclosed embodiment, the sub-timeslot transmission configuration parameter is used to indicate the sub-timeslot resource information occupied by the collaborative repeated transmission of the PUCCH in multiple TRP directions.

[0142] In the embodiments of the present disclosure, dynamic switching between different repetitive transmission schemes can be achieved by configuring sub-time slot transmission configuration parameters. For example, the network device can achieve dynamic switching between scheme 1 and scheme 3 by configuring sub-time slot transmission configuration parameters. And dynamic switching between scheme 2 and scheme 3 can be achieved by dynamically changing the subslot configuration of scheme 3.

[0143] In the embodiment of the present disclosure, sub-time slot transmission configuration parameters may be semi-statically configured through RRC signaling.

[0144] Figure 71 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Figure 7 As shown, the communication method for PUCCH is used in a network device and includes the following steps.

[0145] In step S31, in response to determining that the terminal transmits PUCCH in collaboration in multiple TRP directions, RRC signaling is configured, wherein the RRC signaling includes PUCCH configuration information, and the PUCCH configuration information is configured at the PUCCH resource level, PUCCH resource set level, or PUCCH format level. Sub-time slot configuration length information.

[0146] For example, a subslotLengthForPUCCH parameter at the PUCCH resource level or PUCCH format level is added to the RRC parameter PUCCH_config to configure subslot transmission. For example, the subslotLengthForPUCCH parameter can configure the subslot to have a symbol length of 2, 7 or other values.

[0147] It is understandable that the subslotLengthForPUCCH parameter in the relevant protocol is not used to indicate the subslot resource size for repeated PUCCH transmission. In the embodiment of the present disclosure, the subslotLengthForPUCCH parameter is used to indicate the subslot resource size for repeated PUCCH transmission, thereby achieving dynamic switching between different repeated transmission schemes.

[0148] In the embodiment of the present disclosure, the subslot transmission configuration corresponding to the PUCCH resource can be configured or modified through MAC-CE to achieve dynamic switching between different repeated transmission schemes.

[0149] Among them, in the embodiment of the present disclosure, the sub-time slot transmission configuration parameters can be activated (enable) or deactivated (disable), so that the resource can be directly and dynamically switched between the configuration of the time slot retransmission and sub-time slot retransmission schemes, which is suitable for subsequent scheduling requirements.

[0150] In one implementation, the sub-slot transmission configuration parameters can be activated in the embodiment of the present disclosure to achieve switching from an inter-slot repetition transmission scheme to a sub-slot-based repetition transmission scheme within a time slot, or from a beam-hopping-based repetition transmission scheme within a time slot to a sub-slot-based repetition transmission scheme within a time slot.

[0151] For example, when the current PUCCH configuration scheme is scheme 1, which occupies 2 symbols and retransmits 4 times per time slot, the sub-slot transmission configuration parameters are activated through MAC-CE. The resource configuration mode can be dynamically switched from retransmission between time slots to sub-slot retransmission scheme of scheme 3 without changing other transmission parameters. That is, each sub-slot occupies 2 symbols and retransmits 4 times within the time slot.

[0152] For another example, the current PUCCH configuration scheme is scheme 2 which occupies 7 symbols in a time slot. After activating the sub-slot transmission configuration parameters through MAC-CE, the resource configuration mode can be switched to the sub-slot retransmission scheme, that is, each sub-slot occupies 7 symbols. At the same time, the transmission number parameter needs to be modified to achieve dynamic switching to scheme 3.

[0153] In another implementation, the sub-timeslot transmission configuration parameters can be deactivated in the embodiment of the present disclosure to achieve switching from a sub-timeslot-based repetition transmission scheme within a time slot to an inter-timeslot repetition transmission scheme, or from a sub-timeslot-based repetition transmission scheme within a time slot to a beam-hopping-based repetition transmission scheme within a time slot.

[0154] For example, when the current PUCCH configuration scheme is scheme 1 in which each time slot occupies 2 symbols and is retransmitted 4 times, if the sub-time slot transmission configuration parameter is deactivated, the resource configuration mode is dynamically switched from the sub-time slot retransmission scheme of scheme 3 (each sub-time slot occupies 2 symbols and is retransmitted 4 times within the time slot) to the inter-time slot retransmission scheme of scheme 1.

[0155] For another example, the current PUCCH configuration scheme is scheme 2, which occupies 7 symbols in a time slot. If the sub-slot transmission configuration parameter is deactivated, the resource configuration mode can be dynamically switched from the sub-slot retransmission scheme (each sub-slot occupies 7 symbols) to the inter-slot repeated transmission scheme. And by modifying the transmission number parameter, the dynamic switching between scheme 3 and scheme 2 can be achieved.

[0156] In the embodiment of the present disclosure, the sub-time slot transmission configuration parameter can also be reconfigured as an invalid transmission configuration parameter to achieve dynamic switching of the repeated transmission scheme. For example, by reconfiguring the sub-time slot transmission configuration parameter as an invalid transmission configuration parameter, dynamic switching between the inter-time slot repeated transmission scheme and the intra-time slot sub-time slot based repeated transmission scheme can be achieved.

[0157] In the embodiment of the present disclosure, the sub-time slot transmission configuration parameter is reconfigured to an invalid transmission configuration parameter, which can also be understood as not using the sub-time slot transmission configuration parameter in the currently used repeated transmission scheme.

[0158] In one example, the subslot transmission configuration parameter is reconfigured to an invalid transmission configuration parameter to indicate the use of scheme 1. Alternatively, the subslot size configuration can be directly changed to make it suitable for the current scheduling requirements. For example, the subslotLengthForPUCCH parameter can be configured with a value of "0" to indicate slot-level transmission. In addition, by reconfiguring this parameter under scheme 3 configuration, dynamic switching between scheme 1 and scheme 3 is achieved.

[0159] In one implementation, the disclosed embodiment may also modify the sub-timeslot transmission configuration parameter to the sub-timeslot occupied resource size to implement switching from an inter-timeslot repeated transmission scheme to an intra-timeslot sub-timeslot based repeated transmission scheme.

[0160] For example, by modifying the specific value of the sub-time slot transmission configuration parameter, the specific sub-time slot occupied resource size under scheme 3 is realized. For example, the current configuration of sub-time slots with 7 symbols can be changed to a transmission configuration with sub-time slots with 2 symbols, and directly used for this scheduled transmission.

[0161] In the communication method for PUCCH provided in the embodiment of the present disclosure, dynamic switching between different repetition transmission schemes can also be achieved through the time slot number configuration parameter (nrofslots parameter).

[0162] Figure 8 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Figure 8 As shown, the communication method for PUCCH is used in a network device and includes the following steps.

[0163] In step S41, a time slot number configuration parameter is sent, where the time slot number configuration parameter is used to indicate the number of time slots occupied by collaboratively sending PUCCH for repeated transmission in multiple TRP directions.

[0164] In the disclosed embodiment, the network device configures and sends a time slot number configuration parameter to indicate the number of time slots occupied by collaboratively sending PUCCH for repeated transmission in multiple TRP directions, thereby realizing dynamic switching between scheme 1 and scheme 2, and dynamic switching between scheme 2 and scheme 3.

[0165] In one implementation, in the disclosed embodiment, the transmission number parameter (time slot number configuration parameter) corresponding to the PUCCH resource can be modified through MAC-CE to achieve dynamic switching between different repetitive transmission schemes.

[0166] In one implementation of the disclosed embodiment, the time slot number configuration parameter can be activated or deactivated to achieve direct dynamic switching of resources between the configuration of time slot retransmission and beam hopping beam retransmission schemes, which is suitable for subsequent scheduling requirements.

[0167] For example, in an embodiment of the present disclosure, the time slot number configuration parameter can be activated to achieve switching from a beam hopping-based repetitive transmission scheme within a time slot to an inter-time slot repetitive transmission scheme, or from a beam hopping-based repetitive transmission scheme within a time slot to a sub-time slot-based repetitive transmission scheme within a time slot.

[0168] In one example, when the PUCCH resources of scheme 1 with 4 symbols and 4 times of inter-slot retransmission are configured, the retransmission number parameter K is activated through MAC-CE, and the beam hopping beam retransmission scheme of 4 symbols (i.e. scheme 2) can be switched to the inter-slot repeated transmission scheme (i.e. scheme 1). The same applies to the switching between scheme 2 and scheme 3.

[0169] For another example, in an embodiment of the present disclosure, the time slot number configuration parameter can be deactivated to achieve switching from an inter-time slot repetition transmission scheme to a beam hopping-based repetition transmission scheme within a time slot, or from a sub-time slot-based repetition transmission scheme within a time slot to a beam hopping-based repetition transmission scheme within a time slot.

[0170] In one example, when the PUCCH resource of scheme 1 is configured with 4 symbols and 4 times of inter-slot retransmission, the retransmission number parameter K is deactivated through MAC-CE, and the scheme 2 (i.e., beam hopping retransmission scheme with 4 symbols) is switched to by default. The same applies to the switching between scheme 2 and scheme 3.

[0171] In another implementation of the disclosed embodiment, the time slot number configuration parameters can be reconfigured to achieve switching from an inter-time slot repetition transmission scheme to a beam hopping-based repetition transmission scheme within a time slot, or from a sub-time slot-based repetition transmission scheme within a time slot to a beam hopping-based repetition transmission scheme within a time slot.

[0172] In one example, the parameter configuration for scheme 2 is modified to 1. When the PUCCH resource of scheme 1 is configured with 4 symbols and 4 timeslot retransmission, the time slot number configuration parameter is modified through MAC-CE (retransmission number parameter K=1), then the default switch is made to the beam hopping retransmission scheme of 4 symbols, i.e. scheme 2. The same applies to the switching between scheme 2 and scheme 3.

[0173] In the communication method for PUCCH provided by the embodiment of the present disclosure, dynamic switching between different repetitive transmission schemes can also be achieved through PUCCH resource configuration information. For example, different PUCCH resource configurations corresponding to scheme 1, scheme 2, and scheme 3 transmissions are configured in the same PUCCH resource set. The currently used scheduling transmission scheme is activated by indicating PRI through DCI. Among them, PRI can be understood as a PUCCH resource indication (PUCCH Resource Indicator), which is used to indicate which PUCCH resource transmission in the current PUCCH group is specifically used for this scheduling. It can be further understood that the network device can configure the current PUCCH transmission scheme through RRC signaling.

[0174] Fig. 9 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Fig. 9 As shown, the communication method for PUCCH is used in a network device and includes the following steps.

[0175] In step S51, PUCCH resource configuration information is sent, where the PUCCH resource configuration information includes first PUCCH resource configuration information, or second PUCCH resource configuration information, or third PUCCH resource configuration information.

[0176] Among them, the first PUCCH resource configuration information corresponds to the inter-time slot repetition transmission scheme, the second PUCCH resource configuration information corresponds to the intra-time slot based on beam hopping repetition transmission scheme, and the third PUCCH resource configuration information corresponds to the intra-time slot based on sub-time slot repetition transmission scheme.

[0177] In an embodiment of the present disclosure, a network device sends PUCCH resource configuration information to instruct a terminal to use a repeated transmission scheme corresponding to the PUCCH resource configuration information to collaboratively send PUCCH in multiple TRP directions.

[0178] In one example, the current PUCCH transmission scheme is a repetitive transmission scheme between time slots corresponding to the first PUCCH resource configuration information. If the network device sends a third PUCCH resource configuration information, it can dynamically switch to a sub-time slot-based repetitive transmission scheme within the time slot corresponding to the third PUCCH resource configuration information.

[0179] The communication method for PUCCH provided in the embodiment of the present disclosure realizes switching between different PUCCH channel transmission schemes under multi-TRP transmission through different methods, which can improve the flexibility of scheduling, adapt to channel and service changes more quickly and flexibly, reduce latency, more effectively utilize system resources, and improve system performance.

[0180] Based on the same concept, an embodiment of the present disclosure provides a PUCCH communication method for a terminal.

[0181] Fig.10 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Fig.10 As shown, the communication method for PUCCH is used in a terminal and includes the following steps.

[0182] In step S61, indication information is received, where the indication information is used to instruct the terminal to dynamically switch the repetition transmission scheme to collaboratively repeat the transmission of PUCCH in multiple TRP directions.

[0183] Among them, the repetitive transmission scheme includes an inter-time slot repetitive transmission scheme, a beam hopping-based repetitive transmission scheme within a time slot, and a sub-time slot-based repetitive transmission scheme within a time slot.

[0184] In step S62, based on the indication information, PUCCH is sent collaboratively in multiple TRP directions.

[0185] In the embodiment of the present disclosure, when the terminal cooperates to send PUCCH in multiple TRP directions, different PUCCH transmission schemes can be dynamically switched when data is transmitted in different TRP directions through indication information, so that the terminal can cooperate to send PUCCH in different TRP directions according to different transmission schemes.

[0186] In one implementation provided by the embodiment of the present disclosure, the network device can implement switching of different repetitive transmission schemes by configuring sub-time slot transmission configuration parameters. That is, the network device can indicate the sub-time slot resource information occupied by the collaborative repetitive transmission of PUCCH in multiple TRP directions by sending sub-time slot transmission configuration parameters.

[0187] Fig.11 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Fig.11 As shown, the communication method for PUCCH is used in a terminal and includes the following steps.

[0188] In step S71, a sub-timeslot transmission configuration parameter is received, where the sub-timeslot transmission configuration parameter is used to indicate sub-timeslot resource information occupied by collaboratively repeating the transmission of PUCCH in multiple TRP directions.

[0189] In the disclosed embodiment, the terminal can implement dynamic switching between different repetitive transmission schemes through the received sub-time slot transmission configuration parameters. For example, the terminal implements dynamic switching between scheme 1 and scheme 3 based on the sub-time slot transmission configuration parameters. And the terminal can implement dynamic switching between scheme 2 and scheme 3 through the dynamically changed subslot configuration of scheme 3.

[0190] Fig.12 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Fig.12 As shown, the communication method for PUCCH is used in a terminal and includes the following steps.

[0191] In step S81, RRC signaling is received, where the RRC signaling includes PUCCH configuration information, where the PUCCH configuration information is configured as sub-slot configuration length information at a PUCCH resource level, a PUCCH resource set level, or a PUCCH format level.

[0192] Among them, RRC signaling semi-statically configures sub-time slot transmission configuration parameters.

[0193] For example, a subslotLengthForPUCCH parameter at the PUCCH resource level or PUCCH format level is added to the RRC parameter PUCCH_config to configure subslot transmission. For example, the subslotLengthForPUCCH parameter can configure the subslot to have a symbol length of 2, 7 or other values.

[0194] It is understandable that the subslotLengthForPUCCH parameter in the relevant protocol is not used to indicate the subslot resource size for repeated PUCCH transmission. In the embodiment of the present disclosure, the subslotLengthForPUCCH parameter is used to indicate the subslot resource size for repeated PUCCH transmission, thereby achieving dynamic switching between different repeated transmission schemes.

[0195] In the embodiment of the present disclosure, the subslot transmission configuration corresponding to the PUCCH resource can be configured or modified through MAC-CE to achieve dynamic switching between different repeated transmission schemes.

[0196] Among them, in the embodiment of the present disclosure, the sub-time slot transmission configuration parameter can be activated or deactivated, so that the resource can be directly and dynamically switched between the configuration of the time slot retransmission and the sub-time slot retransmission scheme, which is suitable for subsequent scheduling requirements.

[0197] Fig.13 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Fig.13 As shown, the communication method for PUCCH is used in a terminal and includes the following steps.

[0198] In step S91, in response to the sub-slot transmission configuration parameters being activated, the inter-slot repetition transmission scheme is switched to the sub-slot-based repetition transmission scheme within the time slot, and PUCCH is sent in a collaborative manner in multiple TRP directions, or the intra-slot beam-hopping-based repetition transmission scheme is switched to the sub-slot-based repetition transmission scheme within the time slot, and PUCCH is sent in a collaborative manner in multiple TRP directions.

[0199] Fig.14 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Fig.14 As shown, the communication method for PUCCH is used in a terminal and includes the following steps.

[0200] In step S101, in response to the sub-slot transmission configuration parameter being deactivated, the scheme of repeated transmission based on sub-slots within a time slot is switched to the scheme of repeated transmission between time slots, and PUCCH is sent in a collaborative manner toward multiple TRP directions, or the scheme of repeated transmission based on sub-slots within a time slot is switched to the scheme of repeated transmission based on beam hopping within a time slot, and PUCCH is sent in a collaborative manner toward multiple TRP directions.

[0201] In the embodiment of the present disclosure, the sub-time slot transmission configuration parameter can also be reconfigured as an invalid transmission configuration parameter to achieve dynamic switching of the repeated transmission scheme. For example, by reconfiguring the sub-time slot transmission configuration parameter as an invalid transmission configuration parameter, dynamic switching between the inter-time slot repeated transmission scheme and the intra-time slot sub-time slot based repeated transmission scheme can be achieved.

[0202] Fig.15 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Fig.15 As shown, the communication method for PUCCH is used in a terminal and includes the following steps.

[0203] In step S111, in response to the sub-timeslot transmission configuration parameters being reconfigured to invalid transmission configuration parameters, the inter-timeslot repetition transmission scheme and the sub-timeslot-based repetition transmission scheme within the time slot are dynamically switched, and PUCCH is sent in a collaborative manner in multiple TRP directions.

[0204] In the communication method for PUCCH provided in the embodiment of the present disclosure, dynamic switching between different repetition transmission schemes can also be achieved through the time slot number configuration parameter (nrofslots parameter).

[0205] Fig.16 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Fig.16 As shown, the communication method for PUCCH is used in a terminal and includes the following steps.

[0206] In step S121, in response to the sub-slot transmission configuration parameter being modified to the sub-slot occupied resource size, the inter-slot repetition transmission scheme is switched to the sub-slot-based repetition transmission scheme within the slot, and PUCCH is sent collaboratively in multiple TRP directions.

[0207] In the disclosed embodiment, the terminal may receive a time slot quantity configuration parameter configured and sent by a network device to implement dynamic switching between scheme 1 and scheme 2, and dynamic switching between scheme 2 and scheme 3.

[0208] Fig.17 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Fig.17 As shown, the communication method for PUCCH is used in a terminal and includes the following steps.

[0209] In step S131, a time slot number configuration parameter is received, where the time slot number configuration parameter is used to indicate the number of time slots occupied by collaboratively sending PUCCH for repeated transmission in multiple TRP directions.

[0210] In one implementation of the disclosed embodiment, the time slot number configuration parameter can be activated or deactivated to achieve direct dynamic switching of resources between the configuration of time slot retransmission and beam hopping beam retransmission schemes, which is suitable for subsequent scheduling requirements.

[0211] Fig.181 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Fig.18 As shown, the communication method for PUCCH is used in a terminal and includes the following steps.

[0212] In step S141, in response to the time slot number configuration parameter being activated, the beam hopping-based repetition transmission scheme within the time slot is switched to the inter-time slot repetition transmission scheme, and PUCCH is sent in a collaborative manner towards multiple TRP directions, or the beam hopping-based repetition transmission scheme within the time slot is switched to the sub-time slot-based repetition transmission scheme within the time slot, and PUCCH is sent in a collaborative manner towards multiple TRP directions.

[0213] Fig.19 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Fig.19 As shown, the communication method for PUCCH is used in a terminal and includes the following steps.

[0214] In step S151, in response to the time slot number configuration parameter being deactivated, the scheme is switched from the inter-time slot repetition transmission scheme to the intra-time slot based beam hopping repetition transmission scheme, and PUCCH is collaboratively sent in multiple TRP directions, or the scheme is switched from the intra-time slot based sub-time slot repetition transmission scheme to the intra-time slot based beam hopping repetition transmission scheme, and PUCCH is collaboratively sent in multiple TRP directions.

[0215] In another implementation of the disclosed embodiment, the time slot number configuration parameters can be reconfigured to achieve switching from an inter-time slot repetition transmission scheme to a beam hopping-based repetition transmission scheme within a time slot, or from a sub-time slot-based repetition transmission scheme within a time slot to a beam hopping-based repetition transmission scheme within a time slot.

[0216] Fig. 20 1 is a flow chart of a communication method for PUCCH according to an exemplary embodiment. The communication method for PUCCH can be performed alone or in combination with other embodiments of the present disclosure. Fig. 20 As shown, the communication method for PUCCH is used in a terminal and includes the following steps.

[0217] In step S161, in response to the time slot number configuration parameter being reconfigured, the inter-time slot repetition transmission scheme is switched to the intra-time slot based beam hopping repetition transmission scheme, and PUCCH is sent in a collaborative manner towards multiple TRP directions, or the sub-time slot based repetition transmission scheme is switched to the intra-time slot based beam hopping repetition transmission scheme, and PUCCH is sent in a collaborative manner towards multiple TRP directions.
