[0038] In order to make the purpose, technical solution and advantages of the present application more clear, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

In this application, the 5G system is used as an example for explanation.

[0041] The embodiments of the present application can be used in wireless networks of different standards. The wireless access network may include different communication nodes in different systems. Figure 1 It is a schematic diagram of the structure of a wireless network system. Figure 1 As shown, the wireless network system 100 includes a base station 101, a user equipment 110, a user equipment 120 and a user equipment 130. The base station 101 performs wireless communication with the user equipment 110, the user equipment 120 and the user equipment 130 respectively.

[0042] First of all, it should be noted that in the embodiments of the present application, the base station may be a device that can communicate with the user terminal. The base station may be any device with wireless transceiver functions. Including but not limited to: base station NodeB, evolved base station eNodeB, base station in 5G communication system, base station in future communication system, access node in WiFi system, wireless relay node, wireless backhaul node, etc. The base station may also be a wireless controller in the cloud radio access network (CRAN) scenario; the base station may also be a small station, a transmission reference point (TRP), etc., which is not limited in the embodiments of the present application.

[0043] In the embodiments of the present application, the user terminal is a device with wireless transceiver function that can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as ships, etc.); it can also be deployed in the air (for example, on airplanes, balloons and satellites, etc.). The user terminal can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present application do not limit the application scenarios. The user terminal may sometimes also be referred to as a terminal, an access terminal, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a UE terminal, a wireless communication device, a UE agent or a UE device, etc. The embodiments of the present application are not limited.

[0044] The joint transmission technology of multiple transmission and reception points (Multi-TRP) uses multi-TRP transmission to effectively improve the transmission throughput of Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A) and New Radio Access Technology (NR) in enhanced Mobile Broadband (eMBB) scenarios. Another technology of NR is multi-panel transmission, which uses multiple antenna panels for transmission to obtain higher spectrum efficiency. At the same time, the repetition of sending or receiving using Multi-TRP or Multi panel can increase the probability of the receiving end obtaining correct information, and effectively improve the transmission reliability in ultra-reliable and low latency communications (URLLC) scenarios. However, in the prior art, there are still some problems to be solved in the transmission of uplink control channels in Multi-TRP or Multi panel.

[0045] For the convenience of description, some concepts used in this application are introduced here.

[0046] The transmission content in NR can be divided into data and signaling.

[0047] The physical channels used to transmit signaling include the physical downlink control channel (PDCCH) and the physical uplink control channel (PUCCH). PDCCH is mainly used to transmit physical downlink control information (DCI), and PUCCH is mainly used to transmit uplink control information, such as channel state information (CSI), hybrid automatic repeat request (HARQ), scheduling request, etc.

[0048] The physical channels used to transmit data include the physical downlink shared channel (PDSCH) and the physical uplink shared channel (PUSCH). PDSCH is mainly used to transmit downlink data, while PUSCH is mainly used to transmit uplink data and some uplink control information.

[0049] In order to obtain spatial hierarchical gain, multiple beams can be used for transmission. The specific beam used for transmission or reception depends on the beam indication in beam management. When the base station uses analog beamforming for downlink transmission, the base station needs to indicate the serial number of the downlink analog transmission beam selected by the UE. After receiving the indication, the UE calls the best receiving beam corresponding to the serial number for downlink reception according to the information stored in the beam training pairing process. When the base station schedules the UE to use analog beamforming for uplink transmission, the base station needs to indicate the auxiliary information of the uplink analog transmission beam to the UE. After receiving the auxiliary information, the UE performs uplink transmission according to the uplink analog transmission beam indicated by the base station. The base station can call the receiving beam corresponding to the transmission beam for uplink reception according to the information stored in the beam training pairing process. For the uplink beam indication of PUCCH, the PUCCH radio resources are first configured. Different PUCCH resources are semi-statically configured with different transmission beam directions. By selecting the PUCCH radio resources, different transmission beam directions are selected to achieve beam switching in multiple directions.

[0050] In order to improve the reliability of data or signaling transmission, one way is repetition transmission. The transmission of M data (for example, PDSCH or PUSCH) is repetition, which means that the M data carry exactly the same information, such as M data from the same transport block (Transport Block, TB), but the corresponding redundant versions (Redundancy version, RV) after channel coding are different or independent, and even the RVs after channel coding of the M data are the same. The RV here refers to different redundant versions of the transmitted data after channel coding. Generally speaking, the redundant versions {0, 1, 2, 3} can be taken. Similarly, the transmission of M signaling (such as PDCCH or PUCCH) is repetition, which means that the content carried by the M signaling is the same. For example, the DCI content carried by M PDCCHs is the same (for example, the value of each field is the same), and for example, the UCI content values ​​carried by M PUCCHs are the same. The data of M repetitions (such as M repetition PUSCH or M repetition PDSCH) or the signaling of M repetitions (such as M repetition PUCCH or M repetition PDCCH) can come from N different transmission and reception points (Transmission and Reception Point, TRP), or from N different antenna panels, or N different bandwidth parts (Bandwidth Part, BWP), or N different carrier components (Carrier Component, CC), wherein the N panels or N BWP or N CC can belong to the same TRP or multiple TRPs. The scheme of repeated transmission includes but is not limited to at least one of the following methods: space division multiplexing method Scheme 1, frequency division multiplexing method Scheme 2, time division multiplexing method transmission Scheme 3 within time slots, time division multiplexing method Scheme 4 between time slots. Of course, it can also be any combination of the above multiplexing methods, such as a combination of space division multiplexing and frequency division multiplexing, a combination of time division multiplexing and frequency division multiplexing, etc.

[0051] Bandwidth Part (BWP) is defined as a combination of multiple consecutive resource blocks (RBs) within a carrier. The concept of BWP is introduced to enable UE to better use the large carrier bandwidth. For a large carrier bandwidth, the bandwidth that a UE can use is often very limited. If the UE is required to monitor and maintain the full bandwidth, the terminal will consume a lot of energy. The introduction of BWP is to draw out part of the bandwidth within the entire large carrier bandwidth for UE to access and transmit data. The UE only needs to perform corresponding operations within this part of the bandwidth configured by the system.

[0052] Power control is an important means to increase channel capacity, reduce interference and save energy in wireless communication systems. On the one hand, sufficiently high transmission power helps to apply higher modulation and coding levels (MCS), increase transmission bits, improve transmission success rate and quality of service (QoS), and reduce bit error rate and packet loss rate. On the other hand, too high transmission power will interfere with other transmissions on the same time-frequency resources and increase energy consumption. NR uplink uses the basic power control technology of LTE, namely partial power control (FPC). On the uplink carrier of a given service cell, FPC mainly includes open-loop power control part, closed-loop power control part, and other adjustment quantities. The open-loop part includes the receiving end power target value, path loss estimation and partial path loss compensation factor. The closed-loop part includes the power control offset (adjustment) state value (Power Control Adjustment State), which can quickly adjust the transmission power of a certain UE for a certain transmission. Other adjustment quantities are closely related to resource allocation and link adaptation.

[0053] It should be noted that in the embodiments listed in this application, if not otherwise specified, generally speaking, it includes 1 terminal and at least two TRPs (or the UE includes at least one panel in the case of one TRP), and each TRP transmits N PDSCH repetitions. In this article, the PUCCH repetition of the N PDSCH repetitions is transmitted internally using time division multiplexing.

[0054] In one embodiment, the present application provides a transmission method. Figure 2 A flow chart of a transmission method provided in an embodiment of the present application. The method can be applicable to the case of repeated transmission between a base station and a terminal. The method can be performed by a transmission device provided in the present application, and the transmission device can be implemented by software and / or hardware.

[0055] The transmission method provided in this implementation is mainly used in UE.

[0056] like Figure 2As shown, the transmission method provided in the embodiment of the present application mainly includes step S21.

[0057] S21. Obtain physical uplink control channel PUCCH parameters, and perform repeated transmission in one or more time slots according to the PUCCH parameters; wherein the parameters are configured by high-level signaling, and the parameters include one or more of the following: multiple groups of spatial relationship information, frequency hopping transmission parameters; each spatial relationship information corresponds to a set of power control parameters.

[0058] In this embodiment, frequency hopping refers to the continuous hopping of the carrier frequency. Frequency hopping can expand the effective spectrum, improve the anti-interference capability, and improve the reliability of transmission.

[0059] The power control parameter refers to the parameter that can adjust the transmission power of the beam. Selecting different power control parameters can optimize the beam transmission performance and improve the anti-interference capability.

[0060] The high-layer signaling is configured by the base station and transmitted to the UE via an RRC message.

[0061] In an exemplary implementation, when multiple PUCCH repetition transmissions are located in the same partial wideband BWP, the MAC-CE pairs the configured spatial relationship information to generate N new spatial relationship information groups.

[0062] Pairing the spatial relationship information means pairing N spatial relationship information in pairs to generate N new spatial relationship information groups. Wherein, the spatial relationship information group includes two spatial relationship information. Wherein, N is a positive integer. Preferably, N is 8.

[0063] For example: the configuration spatial relationship information is S0-S7, and the spatial relationship information is paired to generate spatial relationship information groups including (S0, S1), (S1, S2), (S2, S3), (S3, S4), (S4, S5)(S5, S6)(S6, S7)(S7, S7).

[0064] Furthermore, the MAC-CE activation state corresponds to different groups of the spatial relationship information.

[0065] For example: MAC-CE activation states S0-S7 correspond one-to-one to spatial relationship information groups (S0, S1), (S1, S2), (S2, S3), (S3, S4), (S4, S5)(S5, S6)(S6, S7)(S7, S7) respectively.

[0066] It should be noted that the above correspondence is only for illustrative purposes and not for limitation.

[0067] Furthermore, the transmit beam of the UE is determined by the spatial relationship in the spatial relationship information group activated by the MAC-CE.

[0068] Specifically, the transmitting beam of the UE is determined by the first spatial relationship information and the second spatial relationship information in the spatial relationship information group, wherein the first spatial relationship information and the second spatial relationship information are the same, or the first spatial relationship information and the second spatial relationship information are different.

[0069] When MAC-CE activates S1 for the UE, the UE's transmit beam is determined by S1 and S2. When MAC-CE activates S7 for the UE, the UE's transmit beam is determined only by S7, where the UE's transmit beam refers to the spatial relation used to transmit PUCCH or PUSCH.

[0070] It should be noted that the first spatial relationship information and the second spatial relationship information are only two identical or different spatial relationship information in the spatial relationship information group. The first and second do not have the actual meaning of quantity or arrangement, and only distinguish the spatial relationship information.

[0071] Furthermore, when the frequency hopping method is inter-time slot frequency hopping and repeated transmission M times, the transmission beam of the PUCCH on the even time slot is determined by the first spatial relationship information in the spatial relationship information group; the transmission beam of the PUCCH on the odd time slot is determined by the second spatial relationship information in the spatial relationship information group.

[0072] Furthermore, when the frequency hopping method is inter-time slot frequency hopping and repeated transmission M times, the transmission beam of the PUCCH on the first M / 2 time slots is determined by the first spatial relationship information in the spatial relationship information group; the transmission beam of the PUCCH on the remaining time slots is determined by the second spatial relationship information in the spatial relationship information group.

[0073] Furthermore, when the frequency hopping method is frequency hopping within a time slot and repeated transmission M times, the transmission beam of the PUCCH on the even-numbered frequency hopping unit is determined by the first spatial relationship information in the spatial relationship information group; the transmission beam of the PUCCH on the odd-numbered frequency hopping unit is determined by the second spatial relationship information in the spatial relationship information group.

[0074] Furthermore, when the frequency hopping method is frequency hopping within a time slot and repeated transmission M times, the transmission beam of the PUCCH on the first M / 2 frequency hopping units is determined by the first spatial relationship information in the spatial relationship information group; the transmission beam of the PUCCH on the remaining frequency hopping units is determined by the second spatial relationship information in the spatial relationship information group.

[0075] In an exemplary implementation, when PUCCH repetitive frequency hopping transmission is located in different BWPs, the spatial relationship information configured in different BWPs is paired to generate N new groups of spatial relationship information.

[0076] PUCCH repeated frequency hopping transmission in different BWPs can be understood as PUCCH repeated transmission across BWPs.

[0077] When PUCCH performs cross-BWP frequency hopping, the first frequency hopping unit will configure N high-level parameters PUCCH-SpatialRelationInfo0 for PUCCH in BWP0, and the second frequency hopping unit will configure another N high-level parameters PUCCH-SpatialRelationInfo1 for PUCCH in BWP1. At this time, the two groups of PUCCH-SpatialRelationInfo0 and PUCCH-SpatialRelationInfo1 are paired to generate N new groups of PUCCH-SpatialRelationInfo groups. Among them, N is a positive integer. Preferably, N is 8. The grouping result can reuse the grouping method of inter-time slot frequency hopping, or it can be re-grouped.

[0078] Further, the transmit beam of the UE is determined by third spatial relationship information and fourth spatial relationship information in the spatial relationship information group, wherein the third spatial relationship information corresponds to the first BWP, and the fourth spatial relationship information corresponds to the second BWP.

[0079] Furthermore, when the frequency hopping method is inter-time slot frequency hopping and repeated transmission M times, the PUCCH transmission beam of the UE in the time slot within the first BWP is determined by the third spatial information in the spatial relationship information group, and the PUCCH transmission beam of the UE in the time slot within the second BWP is determined by the fourth spatial information in the spatial relationship information group.

[0080] It should be noted that the third spatial relationship information and the fourth spatial relationship information are only two identical or different spatial relationship information in the spatial relationship information group. The third and fourth do not have the actual meaning of quantity or arrangement, and only distinguish the spatial relationship information.

[0081] Furthermore, when the frequency hopping is frequency hopping transmission M times within a time slot, the PUCCH transmission beam of the UE on the frequency hopping unit within the first BWP is determined by the third spatial information in the spatial relationship information group, and the PUCCH transmission beam of the UE on the frequency hopping unit within the second BWP is determined by the fourth spatial information in the spatial relationship information group.

[0082] In an exemplary implementation, when multiple beams are configured, the form in which the UE sends the beam is indicated by one or more of the following indication information:

[0083] Downlink dynamic control information;

[0084] High-level signaling.

[0085] Furthermore, based on the one or more indication information, a starting beam of the PUCCH in repeated transmission and the number of PUCCHs sent corresponding to the beam are determined.

[0086] Furthermore, the starting beam and the number of PUCCHs sent using the beam are determined by a starting beam index and a duration corresponding to a pre-configured indicator value index.

[0087] Specifically, the unit of the duration corresponding to the starting beam is a time slot (frequency hopping between time slots or no frequency hopping) or a frequency hopping unit (frequency hopping within a time slot).

[0088] In an exemplary embodiment, when a time slot fails to meet the PUCCH transmission requirement, the beam after the time slot is transmitted in one of the following ways:

[0089] The beams are extended backwards in sequence, that is, the original beam order is maintained unchanged;

[0090] Maintain the original beam unchanged, that is, delete the beam corresponding to the time slot that does not meet the transmission requirements.

[0091] In an exemplary implementation, when the base station only notifies the power adjustment factor TPC corresponding to the first beam, the power adjustment factor of the second beam is determined using the power adjustment factor TPC.

[0092] Furthermore, the power adjustment factor of the second beam is determined by the power adjustment factor indicated by the base station and the power control parameter corresponding to the first beam.

[0093] Specifically, when the path loss of the second beam is greater than the path loss of the first beam, and the target received power of the second beam is less than the target received power of the first beam after adjustment, the power adjustment factor of the second beam is determined by the target received power of the first beam, the path loss of the first beam, the target received power of the second beam, and the path loss of the second beam.

[0094] In an application example, this embodiment is used to illustrate the problem of beam indication in the case of PUCCH inter-slot Frequency Hopping.

[0095] In order to further improve the coverage of PUCCH, NR also supports repeated transmission of long PUCCH format 1 / 3 / 4 on the basis of long PUCCH, that is, multi-slot PUCCH aggregation. The number of repeated transmissions can be configured by high-level signaling In the repeatedly transmitted time slot, the multi-slot PUCCH has the same starting symbol and duration. In the multi-slot PUCCH, in order to obtain the frequency classification gain, the inter-slot PUCCH frequency hopping is additionally introduced. If inter-slot frequency hopping is configured, the configuration of the PRB index of the first hopping unit (indicated by the starting PRB) is applied to the even-numbered time slot index in the multi-slot PUCCH, and the configuration of the PRB index of the second hopping unit (indicated by the second PRB) is applied to the odd-numbered time slot index in the multi-slot PUCCH.

[0096] Figure 3 is a schematic diagram of inter-time slot frequency hopping provided in an embodiment of the present application, such as Figure 3 As shown, the RB of slot0 and the RB of slot1 are not in the same frequency range, but frequency hopping occurs. Further, the frequency range of even-numbered time slots is consistent, the frequency range of odd-numbered time slots is consistent, and the frequency range of even-numbered time slots is inconsistent with that of odd-numbered time slots.

[0097] Here, it is mainly used to illustrate how multiple beams are applied to multiple PUCCH repetitions.

[0098] In R15, on each BWP, PUCCH can be configured with up to 8 high-level parameters PUCCH-SpatialRelation Info, including beam-related reference signals (RS), power control-related parameters pucch-PathlossReferenceRS-Id, p0-PUCCH-Id, and closed loop index (CLI). And indicated by MAC CE signaling, MAC CE signaling includes a bitmap of PUCCH-SpatialRelationInfo, which is 7 bits long.

[0099] Figure 4 is a schematic diagram of a bitmap provided in an embodiment of the present application, such as Figure 4As shown, the length of the Bitmap containing PUCCH-SpatialRelationInfo is 7 bits. Among them, Si represents the activation status of the PUCCH spatial-relation information corresponding to PUCCH-SpatialRelationInfoId i. When Si is set to 1, it means that the PUCCH spatial-relation information corresponding to PUCCH-SpatialRelationInfoId i should be activated. When Si is set to 0, it means that the PUCCH spatial-relation information corresponding to PUCCH-SpatialRelationInfoIdi should be deactivated. And the PUCCH spatial-relation information of only one PUCCH resource can be activated at a time.

[0100] In R17, the PUCCH repetition multi-beam transmission mode is considered to obtain spatial hierarchical gain. The corresponding beam configuration is divided into the following two cases.

[0101] 1. PUCCH is configured with inter-slot frequency hopping and is not transmitted across BWP.

[0102] When PUCCH repetition is transmitted in the same BWP, the activated upper BWP will configure n high-level parameters PUCCH-SpatialRelationInfo for PUCCH. At this time, these n PUCCH-SpatialRelationInfo are paired to generate n new PUCCH-SpatialRelationInfo groups. The grouping result can be the following method, but is not limited to this method. The grouping method is shown in Table 1.

[0103] Table 1 PUCCH-SpatialRelationInfo group

[0104]

[0105] Taking the grouping method in Table 1 as an example, when MAC-CE activates S1 for the UE, the UE's transmit beam is determined by S1 and S2. The PUCCH repetition repetition number is configured at the high level. When the UE sends, it can use a circular method as shown in the attached diagram. Figure 5 shown.

[0106] Figure 5 is a schematic diagram of a UE beam transmission method provided in an embodiment of the present application, such as Figure 5As shown, the PUCCH on slot 0 and slot 2 is transmitted using S1 activated in PUCCH-SpatialRelationInfo, and the PUCCH on slot 1 and slot 3 is transmitted using S2 activated in PUCCH-SpatialRelationInfo.

[0107] UE can also send in a sequential manner as shown in the attached diagram Figure 6 shown. Figure 6 is a schematic diagram of a UE beam transmission method provided in an embodiment of the present application, such as Figure 6 As shown, the PUCCH on slot 0 and slot 1 is transmitted using S1 activated in PUCCH-SpatialRelationInfo, and the PUCCH on slot 2 and slot 3 is transmitted using S2 activated in PUCCH-SpatialRelationInfo.

[0108] When MAC-CE activates S7 for the UE, the UE's transmit beam is determined only by S7. The PUCCH repetition transmission times are configured at the higher level. When the UE sends the schematic diagram as shown in the attached Figure 7 shown. Figure 7 is a schematic diagram of a UE beam transmission method provided in an embodiment of the present application, such as Figure 7 As shown, at this time, the UE can use the same beam to send PUCCH on different time slots without beam switching.

[0109] 2. PUCCH configures inter-slot frequency hopping and cross-BWP transmission

[0110] When PUCCH performs cross-BWP frequency hopping, the first frequency hopping unit will configure n high-level parameters PUCCH-SpatialRelationInfo0 for PUCCH in BWP0, and the second frequency hopping unit will configure another n high-level parameters PUCCH-SpatialRelationInfo1 for PUCCH in BWP1. At this time, the two groups of PUCCH-SpatialRelationInfo0 and PUCCH-SpatialRelationInfo1 are paired to generate n new groups of PUCCH-SpatialRelationInfo groups. The grouping results can be as follows, but are not limited to this method. The grouping method is shown in Table 2.

[0111] Table 2 PUCCH-SpatialRelationInfo group

[0112]

[0113] The grouping method of PUCCH-SpatialRelationInfo group is shown in Table 2, where S0i represents the Si activated in PUCCH-SpatialRelationInfo0 configured by the high-level layer in BWP0, and S1i represents the Si activated in PUCCH-SpatialRelationInfo1 configured by the high-level layer in BWP1.

[0114] Therefore, when PUCCH is configured to perform inter-BWP time slot hopping, the activation state of MAC-CE directly corresponds to PUCCH-SpatialRelationInfo group. For example, MAC-CE activates S1 for UE. At this time, the UE's transmit beam in BWP0 is determined by S01, and the transmit beam in BWP1 is determined by S11, thus realizing the correspondence between BWP and beam. PUCCH repetition is configured at the high level. When the UE beam is transmitted, the schematic diagram is as shown in the attached figure. Figure 8 shown.

[0115] Figure 8 is a schematic diagram of a UE beam transmission method provided in an embodiment of the present application, such as Figure 8 As shown, Figure 8 As shown, the PUCCHs on even slots and odd slots are transmitted on different BWPs, respectively. The PUCCHs on slot0 and slot 2 use S01 activated in PUCCH-SpatialRelationInfo0, and the PUCCHs on slot 1 and slot 3 use S11 activated in PUCCH-SpatialRelationInfo1.

[0116] In an application example, this embodiment is used to illustrate the problem of beam indication in the case of intra-slot Frequency Hopping of PUCCH timeslot.

[0117] In LTE, all PUCCH formats must support frequency hopping to obtain frequency classification gain. However, in NR, considering the flexibility of system design, the frequency of all PUCCH formats with more than or equal to 2 symbols is configurable.

[0118] Fig. 9 is a schematic diagram of the frequency hopping unit corresponding to OFDM in the embodiment of the present application, such as Fig. 9 As shown, for a PUCCH with an OFDM symbol length of N, if intra-slot frequency hopping is configured, the number of OFDM symbols in the first frequency hopping unit is The configuration of the PRB index is indicated by startingPRB; the number of OFDM symbols in the second frequency hopping unit is The configuration of the PRB index is indicated by secondPRB.

[0119] Fig.10 is a schematic diagram of frequency hopping within a time slot provided in an embodiment of the present application, such as Fig.10 As shown, in order to further improve the coverage of PUCCH, it can be repeatedly sent based on frequency hopping within the time slot, and the number of repeated transmissions can be configured by high-level signaling. In the repeatedly transmitted time slot, the multi-slot PUCCH has the same starting symbol and duration.

[0120] On each BWP, PUCCH can be configured with up to 8 higher-level parameters PUCCH-SpatialRelationInfo, which are indicated by MAC CE.

[0121] In R17, the PUCCH repetition multi-beam transmission mode is considered to obtain spatial hierarchical gain. The corresponding beam configuration is divided into the following two cases.

[0122] 1. PUCCH is configured with frequency hopping within the time slot and is not transmitted across the BWP

[0123] When PUCCH repetition is transmitted in the same BWP, the activated upper BWP will configure 8 high-level parameters PUCCH-SpatialRelationInfo for PUCCH. At this time, these 8 PUCCH-SpatialRelationInfo are paired to generate n new PUCCH-SpatialRelationInfo groups. The grouping result can reuse the grouping result of inter-time slot frequency hopping, or generate a new grouping method.

[0124] Here we take the grouping method in Table 1 as an example. When MAC-CE activates S1 for the UE, the UE's transmit beam is determined by S1 and S2. The PUCCH repetition number is configured at the high level. When the UE sends, it can use a circular method as shown in the attached diagram. Fig.11 shown.

[0125] Fig.11 is a schematic diagram of a UE beam transmission method provided in an embodiment of the present application, such as Fig.11As shown, the PUCCH on the even-numbered hopping unit uses S1 activated in PUCCH-SpatialRelationInfo for transmission, and the PUCCH on the odd-numbered hopping unit uses S2 activated in PUCCH-SpatialRelationInfo for transmission. The UE can also send in a sequential manner.

[0126] 2. PUCCH is configured with frequency hopping within the time slot and is not transmitted across the BWP

[0127] When PUCCH performs cross-BWP frequency hopping, the first frequency hopping unit will configure 8 high-level parameters PUCCH-SpatialRelationInfo0 for PUCCH in BWP0, and the second frequency hopping unit will configure another 8 high-level parameters PUCCH-SpatialRelationInfo1 for PUCCH in BWP1. At this time, the two groups of PUCCH-SpatialRelationInfo0 and PUCCH-SpatialRelationInfo1 are paired to generate 8 new groups of PUCCH-SpatialRelationInfo groups. The grouping results can reuse the grouping method of inter-time slot frequency hopping, or they can be re-grouped.

[0128] The PUCCH-SpatialRelationInfo group grouping method can be as shown in Table 1, but is not limited to this method, where S0i represents the Si activated in the PUCCH-SpatialRelationInfo0 configured by the high-level layer in BWP0, and S1i represents the Si activated in the PUCCH-SpatialRelationInfo1 configured by the high-level layer in BWP0.

[0129] Therefore, when PUCCH is configured to hop across BWP timeslots, the activation state of MAC-CE directly corresponds to the PUCCH-SpatialRelationInfo group. For example, MAC-CE activates S1 for the UE. At this time, the UE's transmit beam in BWP0 is determined by S01, and the transmit beam in BWP1 is determined by S11. The PUCCH repetition number of repetitions is configured at the higher level. When the schematic diagram is as attached Fig.12 shown.

[0130] Fig.12 is a schematic diagram of a UE beam transmission method provided in an embodiment of the present application, such as Fig.12As shown, the PUCCHs on even slots and odd slots are transmitted on different BWPs, respectively. The PUCCHs on slot 0 and slot 2 use S01 activated in PUCCH-SpatialRelationInfo0, and the PUCCHs on slot 1 and slot 3 use S11 activated in PUCCH-SpatialRelationInfo1.

[0131] In an applicable implementation manner, this embodiment is used to illustrate the design problem of multi-beam beam indication in the case of PUCCH repetition.

[0132] In the case of repeated transmission of PUCCH configuration, it can be seen from the above embodiments that MAC CE will configure multiple beams for the UE.

[0133] Fig.13 is a schematic diagram of a beam transmission method provided in an embodiment of the present application, such as Fig.13 As shown, the UE can select beams for transmission in a cyclic, sequential, and grouped manner.

[0134] The present invention is used to determine how to select a beam transmission mode after multi-beam transmission is configured for UE.

[0135] In R15, on each BWP, PUCCH can be configured with up to 8 high-level parameters PUCCH-SpatialRelationInfo. The UE can obtain the beam-related parameters referenceSignal, power control-related parameters pucch-PathlossReferenceRS-Id, p0-PUCCH-Id, and closedLoopIndex based on the PUCCH-SpatialRelationInfo activated by MAC CE to determine the transmission beam and the corresponding transmission power. When MAC CE configures multiple beams for the UE, the Start and Length Indicator Value (SLIV) in the time domain allocation can be used to further indicate the UE's beam transmission method (it can also be indicated by high-level or DCI dynamic indication).

[0136] The UE can obtain the starting beam index value S of the PUCCH in repeated transmission and the duration L corresponding to the beam according to this indication value. The starting beam index value S indicates which beam among the multiple beams indicated by the MAC CE is used for the first time in PUCCH transmission. The duration L indicates the continuous transmission time of each beam. Considering the existence of inter-slot hopping and intra-slot hopping, the unit of the duration is the minimum value of the transmission opportunity and the hopping unit length. The specific settings are shown in Table 3.

[0137] Table 3 Beam duration unit settings

[0138]

[0139] The corresponding start and length indication values ​​are configured for the UE, and an index value can be selected from a table to indicate the UE. If the value of the beam indication is m, the UE can obtain the corresponding start beam and beam duration from the row with index number m+1 in the table. The table is designed as follows, but is not limited to this design method.

[0140] Table 4 Start and length indication value table

[0141]

[0142]

[0143] In the case of inter-slot frequency hopping, taking the grouping method of PUCCH-SpatialRelationInfo Table 1 as an example, when MAC-CE activates S1 for the UE, the UE's transmit beam is determined by S1 and S2, corresponding to beam index values ​​0 and 1 respectively. The PUCCH repetition repetition number is configured at the high level. When the indication value is 1, the UE beam transmission method is shown in the attached figure. Fig.14 shown.

[0144] Fig.14 is a schematic diagram of a beam transmission method provided in an embodiment of the present application, such as Fig.14 As shown, when the start and length indication values ​​are 1, the start beam index is 0, corresponding to the activated S1, corresponding to the duration 2, and the duration unit is the time slot in the case of inter-slot frequency hopping, so the same beam is used for transmission in slot 0 and slot 1. In slot 3, switch to the next transmission beam S2, and perform beam switching after sending 2 time slots.

[0145] The number of PUCCH repetitions is configured at the higher level. When the indication value is 5, the UE beam transmission method is shown in the attached figure. Fig.15 shown.

[0146] Fig.15 is a schematic diagram of a beam transmission method provided in an embodiment of the present application, such as Fig.15As shown in the figure, when the start and length indication values ​​are 5, the start beam index is 1 corresponding to the activated S2, corresponding to the duration 4, and the duration unit is the time slot in the case of inter-slot frequency hopping, so the same beam is used for transmission in slot 0 to slot 3. In slot 4, switch to the next transmission beam S0, and send 4 time slots to complete the PUCCH repetition transmission.

[0147] In the case of intra-slot frequency hopping, taking the grouping method of PUCCH-SpatialRelationInfo Table 1 as an example, when MAC-CE activates S1 for the UE, the UE's transmit beam is determined by S1 and S2, corresponding to beam index values ​​0 and 1 respectively. The PUCCH repetition transmission times are configured at the high level When the indication value is 1, the UE beam transmission method is shown in the attached figure. Fig.16 shown.

[0148] Fig.16 is a schematic diagram of a beam transmission method provided in an embodiment of the present application, such as Fig.16 As shown in the figure, when the start and length indication values ​​are 1, the start beam index is 0 corresponding to the activated S1, corresponding to the duration 2, and the duration unit is the frequency hopping unit in the case of intra-frequency hopping, so the same beam is used for transmission in the first two frequency hopping units, that is, slot 0. Switch to the next transmission beam in slot 1, and perform beam switching after two frequency hopping units and 2 time slots.

[0149] The number of PUCCH repetitions is configured at the higher level. When the indication value is 5, the UE beam transmission method is shown in the attached figure. Fig.17 shown.

[0150] Fig.17 is a schematic diagram of a beam transmission method provided in an embodiment of the present application, such as Fig.17 As shown, when the start and length indication values ​​are 5, the start beam index is 1 corresponding to the activated S11, corresponding to the duration 4, and the duration unit is the frequency hopping unit in the case of inter-slot frequency hopping, so the same beam is used for transmission in slot 0 and slot 1. In slot 2, switch to the next transmit beam and send 4 frequency hopping units to complete the PUCCH repetition transmission.

[0151] In an applicable embodiment, this embodiment is used to illustrate the beam indication situation when the uplink OFDM symbols in some time slots do not meet the requirement of the multi-slot PUCCH duration during multi-slot PUCCH repetition.

[0152] In the NR frame structure, some time slots contain not only uplink OFDM symbols, but also downlink OFDM symbols and guard intervals. Therefore, the number of uplink OFDM symbols or the number of consecutive OFDM symbols contained in these time slots cannot meet the multi-slot PUCCH's requirement for the duration of each PUCCH. When these time slots do not meet the transmission requirements, the multi-slot PUCCH will skip these time slots and continue to send repeatedly in the next time slot until the number of PUCCHs sent meets the number of repetitions configured by the high-level layer.

[0153] The number of PUCCH repetitions is configured at the higher level. When there is a time slot that does not meet the PUCCH transmission requirements, the UE sends a PUCCH repetition as shown in the attached figure. Fig.18 shown.

[0154] Fig.18 Schematic diagram of UE sending PUCCH repetition according to an embodiment of the present application, such as Fig.18 As shown, slot 1 and slot 4 do not meet the transmission requirements of PUCCH, so four repetitions of high-level instructions are respectively completed in slot 0, slot 2, slot 3 and slot 5. This will affect the corresponding beam configuration, and the present invention is used to determine a solution when the above problem occurs.

[0155] Fig.19 This is a schematic diagram of the beam transmission method provided in the embodiment of the present application. It is assumed that the PUCCHrepetition repetition transmission times are configured at the high level. And the four consecutive time slots all meet the PUCCH transmission requirements. The UE's transmission beam diagram is shown in the attached figure. Fig.19 shown.

[0156] When slot 1 does not meet the transmission requirements of PUCCH, slot 2 and slot 3 can have the following two transmission schemes, but are not limited to the following schemes:

[0157] (1) The beams are extended backwards one by one. Fig. 20 This is a schematic diagram of the beam sending method provided in an embodiment of the present application. Slot 2 uses the beam corresponding to slot 1, slot 3 uses the beam corresponding to slot 2, and the beam of slot 3 is used in the subsequent time slot that meets the PUCCH transmission requirements.

[0158] (2) Maintain the original beam unchanged. Fig.21 is a schematic diagram of a beam transmission method provided in an embodiment of the present application, such as Fig.21As shown, slot 2 and slot 3 still keep the original transmission beams unchanged, and the beam of slot 2 is used in the subsequent time slots that meet the PUCCH transmission requirements.

[0159] In an applicable embodiment, the present invention is used to explain the problem that during PUCCH repetition transmission, a base station indicates a transmission power control command (TPC command) corresponding to power control parameters of multiple transmissions.

[0160] When multiple spatial relation information is configured for the UE, multiple transmit beams of the UE are generated according to different spatial relation information, where the power control parameters corresponding to each spatial relation information include: the open-loop receiving end power target value index j, the index of the path loss estimation pathlossReferenceRSs and the index of the closed-loop loop. Based on the above parameters, the UE can calculate the corresponding transmit power using the following formula.

[0161] P=min[P CMAX ,{P0(j)+α(k)·PL(q)}+{f(l)}+{10lgM+Δ}][dBm]

[0162] Among them, PL(q) is the path loss estimate; P0(j) is the open-loop receiving end power target value; α(k) is the partial path loss compensation factor, which is 1 for PUCCH; f(l) is the power control offset state value; 10lgM+Δ is other adjustment quantities. The power control offset state value (Power Control Adjustment State) of the closed-loop part is carried by physical layer signaling DCI 1_0 and DCI 1_1, and can also be combined with the power control commands of multiple terminals through DCI 2_2. This closed-loop power control information is called the transmission power control command (TPC command). In the case of PUCCH repetition transmission, DCI will only indicate one TPC for rapid power adjustment. The power adjustment value corresponding to TPC is shown in the table. When the performance of multiple beams is very different (for example, when the beam is blocked), the power adjustment indicated by the base station will only match one of the transmit beams, and will not match other transmit beams.

[0163] Fig. 22 is a schematic diagram of a beam being blocked in an embodiment of the present application, such as Fig. 22 As shown, the UE's transmit beam 1 can be directly transmitted to the base station through path 1. The UE's transmit beam 2 is blocked due to the presence of the bus, which causes the power adjustment indicated by the base station to only match transmit beam 1, but not transmit beam 2.

[0164] Table 5 Mapping of TPC command fields in DCI format 1_0 or DCI format 1_1 or DCI format 2_2

[0165] TPC Command Field <![CDATA[Accumulatedδ PUCCH,b,f,c [dB]]]> 0 -1 1 0 2 1 3 3

[0166] like Fig. 22 As shown, the UE is configured with two transmission beams, namely beam 1 and beam 2, corresponding to different path losses 1 and 2. At this time, path 2 is blocked and has a larger path loss. The base station will find that the UE's transmission power is too low; while the transmission conditions of path 1 are better, the base station will find that the UE's transmission power is too high. If the base station instructs TPC to notify the UE to reduce the transmission power by 1dB for beam 1 at this time, it should also reduce it by 1dB when sending beam 2. However, the path loss corresponding to beam 2 is originally larger, and the transmission performance will be further deteriorated after the transmission power is reduced. However, if the base station instructs TPC to notify the UE to increase the transmission power by 1dB for beam 2 at this time, it should also increase it by 1dB when sending beam 1. This will cause the corresponding transmission power of beam 1 to be too high, and even interfere with the transmission of the same time-frequency resources, and consume too much energy, which is not conducive to energy saving.

[0167] Therefore, this application considers the power control problem of each beam when the performance of multiple beams varies greatly, but the base station only notifies one TPC.

[0168] Assume that the path loss corresponding to beam i is PL(i) and the target received power is P0(i); the path loss corresponding to beam j is PL(j) and the target received power is P0(j). When the base station indicates a TPC=δ(i) for beam i through DCI, beam j will be adaptively adjusted according to its own target received power. The corresponding δ(j) of beam j can be simply obtained as:

[0169] δ(j)=δ(i)+P0(i)-P0(j)

[0170] However, considering that the path losses corresponding to beam i and beam j are different, when the path loss corresponding to beam j is large, if the calculated adaptive adjustment value is very large, it will cause excessive power, resulting in waste of resources and even interference with other transmission signals. Therefore, it is necessary to consider the adaptive adjustment scheme in this case separately.

[0171] Let δ = δ(i) + P0(i) - P0(j). When δ > 0, considering the target received power and path loss factors, we can further obtain δ(j) corresponding to beam j as:

[0172]

[0173] Summarizing the above formulas, we can obtain the final δ(j) corresponding to beam j as:

[0174]

[0175] According to the above formula, we can calculate the δ(j) corresponding to beam j. The UE will adjust the transmit power accordingly. Therefore, the transmit power of multiple beams can be adjusted when only one TPC indicated by DCI is used on the base station side to match multiple sets of power control parameters of multiple beams.

[0176] In one embodiment, the present application provides a transmission device, Fig.23 This is a schematic diagram of the structure of a transmission device provided in an embodiment of the present application. The method can be applicable to the case where repeated transmission is performed between a base station and a terminal. The method can be executed by a transmission device provided in the present application, and the transmission device can be implemented by software and / or hardware.

[0177] like Fig.23 As shown, the transmission device provided in the embodiment of the present application mainly includes a transmission module 231.

[0178] Among them, the transmission module 231 is configured to obtain the physical uplink control channel PUCCH parameters and perform one or more time slot repeated transmission according to the PUCCH parameters; wherein the parameters are configured by high-level signaling, and the parameters include one or more of the following: multiple groups of spatial relationship information, frequency hopping transmission parameters; each spatial relationship information corresponds to a set of power control parameters.

[0179] In an exemplary implementation, when multiple PUCCH repetitive transmissions are located in the same partial wideband BWP, the spatial relationship information configured by the MAC-CE is paired to generate N new groups of spatial relationship information.

[0180] Furthermore, the MAC-CE activation state corresponds to different groups of the spatial relationship information.

[0181] Furthermore, the transmit beam of the UE is determined by the spatial relationship in the spatial relationship information group activated by the MAC-CE.

[0182] Specifically, the transmitting beam of the UE is determined by the first spatial relationship information and the second spatial relationship information in the spatial relationship information group, wherein the first spatial relationship information and the second spatial relationship information are the same, or the first spatial relationship information and the second spatial relationship information are different.

[0183] Furthermore, when the frequency hopping method is inter-time slot frequency hopping and repeated transmission M times, the transmission beam of the PUCCH on the even time slot is determined by the first spatial relationship information in the spatial relationship information group; the transmission beam of the PUCCH on the odd time slot is determined by the second spatial relationship information in the spatial relationship information group.

[0184] Furthermore, when the frequency hopping method is inter-time slot frequency hopping and repeated transmission M times, the transmission beam of the PUCCH on the first M / 2 time slots is determined by the first spatial relationship information in the spatial relationship information group; the transmission beam of the PUCCH on the remaining time slots is determined by the second spatial relationship information in the spatial relationship information group.

[0185] Furthermore, when the frequency hopping method is frequency hopping within a time slot and repeated transmission M times, the transmission beam of the PUCCH on the even-numbered frequency hopping unit is determined by the first spatial relationship information in the spatial relationship information group; the transmission beam of the PUCCH on the odd-numbered frequency hopping unit is determined by the second spatial relationship information in the spatial relationship information group; wherein the first spatial relationship information and the second spatial relationship information are different.

[0186] Furthermore, when the frequency hopping method is frequency hopping within a time slot and repeated transmission M times, the transmission beam of the PUCCH on the first M / 2 frequency hopping units is determined by the first spatial relationship information in the spatial relationship information group; the transmission beam of the PUCCH on the remaining frequency hopping units is determined by the second spatial relationship information in the spatial relationship information group.

[0187] In an exemplary implementation, when PUCCH repetitive transmission is located in different BWPs, the spatial relationship information configured in different BWPs is paired to generate N new spatial relationship information groups.

[0188] Further, the transmit beam of the UE is determined by third spatial relationship information and fourth spatial relationship information in the spatial relationship information group, wherein the third spatial relationship information corresponds to the first BWP, and the fourth spatial relationship information corresponds to the second BWP.

[0189] Furthermore, when the frequency hopping method is inter-time slot frequency hopping and repeated transmission M times, the PUCCH transmission beam of the UE in the time slot within the first BWP is determined by the third spatial information in the spatial relationship information group, and the PUCCH transmission beam of the UE in the time slot within the second BWP is determined by the fourth spatial information in the spatial relationship information group.

[0190] Furthermore, when the frequency hopping method is frequency hopping within a time slot and repeated transmission M times, the PUCCH transmission beam of the UE on the frequency hopping unit within the first BWP is determined by the third spatial information in the spatial relationship information group, and the PUCCH transmission beam of the UE on the frequency hopping unit within the second BWP is determined by the fourth spatial information in the spatial relationship information group.

[0191] In an exemplary implementation, when multiple beams are configured, the form in which the UE sends the beam is indicated by one or more of the following indication information:

[0192] Downlink dynamic control information;

[0193] High-level signaling.

[0194] Furthermore, based on the one or more indication information, a starting beam of the PUCCH in repeated transmission and the number of PUCCHs sent corresponding to the beam are determined.

[0195] Furthermore, the starting beam and the number of PUCCHs sent using the beam are determined by a starting beam index and a duration corresponding to a pre-configured indicator value index.

[0196] Specifically, the unit of the duration corresponding to the starting beam is a time slot (frequency hopping between time slots or no frequency hopping) or a frequency hopping unit (frequency hopping within a time slot).

[0197] In an exemplary embodiment, when a time slot fails to meet the PUCCH transmission requirement, the beam after the time slot is transmitted in one of the following ways:

[0198] The beams are extended backwards in sequence, that is, the original beam order is maintained unchanged;

[0199] Maintain the original beam unchanged, that is, delete the beam corresponding to the time slot that does not meet the transmission requirements.

[0200] In an exemplary implementation, when the base station only notifies that the first beam has a corresponding power adjustment factor TPC, the adjustment factor of the second beam is determined using the power adjustment factor TPC.

[0201] Furthermore, the power adjustment factor of the second beam is determined by the power adjustment factor indicated by the base station and a power control parameter corresponding to the first beam.

[0202] Specifically, when the path loss of the second beam is greater than the path loss of the first beam, and the target received power of the second beam is less than the adjusted target received power of the first beam, the power adjustment factor of the second beam is determined by the target received power of the first beam, the path loss of the first beam, the target received power of the second beam, and the path loss of the second beam.
