[0034] In order to make the objectives, technical solutions and advantages of this application more clear, the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0035] The steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions. Also, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be performed in an order different from that shown here.
[0036] The following is a brief description of the concepts involved in this application:
[0037] In NR, the transmission content can be divided into data and signaling. The physical channels used to transmit signaling include the physical downlink control channel (PDCCH) and the physical uplink control channel (PUCCH). Among them, the PDCCH is mainly used to transmit physical downlink control signaling (DCI), while the PUCCH is mainly used to transmit uplink control information (UCI), such as channel state information (CSI), hybrid automatic repeat request (HARQ), scheduling request, etc. The physical channels used to transmit data include the physical downlink shared channel (PDSCH) and the physical uplink shared channel (PUSCH). The PDSCH is mainly used to transmit downlink data, and the PUSCH is mainly used to transmit uplink data and some uplink control information.
[0038] To achieve spatial hierarchical gain, multi-beam transmission can be performed. 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 sequence number of the selected downlink analog transmit beam to the user equipment (UE). After receiving the indication, the UE uses the optimal receive beam corresponding to this sequence number for downlink reception based on the information stored during the beam training and pairing process. When the base station schedules the UE to use analog beamforming for uplink transmission, the base station needs to indicate auxiliary information for the uplink analog transmit beam to the UE. After receiving the auxiliary information, the UE performs uplink transmission based on the uplink analog transmit beam indicated by the base station. The base station uses the receive beam corresponding to this transmit beam for uplink reception based on the information stored during the beam training and pairing process. For PUCCH uplink beam indication, the PUCCH radio resources are first configured. Different PUCCH resources are semi-statically assigned different transmit beam directions. By selecting the PUCCH radio resources, different transmit beam directions are selected, enabling beam switching in multiple directions.
[0039] In order to improve the reliability of data or signaling transmission, one method is repetition. The repetition of M data (e.g., PDSCH or PUSCH) transmissions means that the M data carry exactly the same information, such as M data from the same transport block (TB), but the corresponding redundancy versions (RV) after channel coding are different or independent, or even the M data have the same RV after channel coding. RV refers to different redundancy versions after channel coding of the transmitted data. Generally speaking, the channel version {0, 1, 2, 3} can be taken. Similarly, the repetition of M signaling (e.g., PDCCH or PUCCH) transmissions means that the content carried by the M signaling is the same, such as the DCI content carried by the M PDCCHs is the same (e.g., the value of each field is the same), and the UCI content value carried by the M PUCCHs is the same. Among them, M repeated data (such as M repeated PUSCHs or M repeated PDSCHs) or M repetition signaling (such as M repeated PUCCHs or M repeated PDCCHs) can come from or be sent to M different TRPs, or from M different antenna panels, or M different bandwidth parts (Bandwidth Parts, BWPs), or M different carrier components (Carrier Components, CCs), wherein the M panels or M BWPs or M CCs can belong to the same TRP or to multiple TRPs. The scheme for repeated transmission includes but is not limited to at least one of the following methods: spatial division multiplexing, i.e., method 1 (Scheme 1), frequency division multiplexing, i.e., method 2 (Scheme 2), time division multiplexing within a time slot, i.e., method 3 (Scheme 3), time division multiplexing between time slots, i.e., method 4 (Scheme 4). It can also be any combination of the above multiplexing methods, such as a combination of spatial division multiplexing and frequency division multiplexing, a combination of time division multiplexing and frequency division multiplexing, etc.
[0040] In the embodiments of the present application, unless otherwise specified, generally speaking, it includes one terminal and at least two TRPs (or in the case of one TRP, the UE includes at least one panel). In the present application, the N PUCCHs are repeatedly transmitted using time division multiplexing.
[0041] In an exemplary embodiment, Figure 1This is a flowchart of a configuration method provided in an embodiment of the present application. This method can be applied to configuring spatial relationships in uplink channel transmission. The method can be performed by a configuration device provided in this application. The configuration device can be implemented in software and / or hardware and integrated on a first communication node. The first communication node includes, but is not limited to, user equipment.
[0042] like Figure 1 As shown, the configuration method provided by this application includes the following steps:
[0043] S110: Acquire transmission instruction information.
[0044] The transmission indication information can be considered as information indicating the transmission of an uplink control channel. The transmission indication information can indicate the spatial relationship associated with the uplink control channel, as well as the frequency hopping configuration and repeated transmission configuration of the uplink control channel. After obtaining the transmission indication information, the first communication node can determine the spatial relationship and matching relationship corresponding to the repeated transmission of the uplink control channel based on the transmission indication information, so as to facilitate the transmission of the uplink control channel based on the determined spatial relationship.
[0045] The content of the transmission indication information is not limited here, as long as it can indicate one or more spatial relationships associated with the uplink control channel during repeated transmission.
[0046] Exemplarily, the spatial relationship associated with two PUCCHs may be activated simultaneously at the same time, so that one PUCCH resource may be associated with two beams, and the transmission indication information may indicate the associated spatial relationship.
[0047] When transmitting indication information to configure the spatial relationship, the uplink control channel may be associated with one or more spatial relationships by activating the status of one or more spatial relationships; or the uplink control channel may be associated with one or more spatial relationships by activating the group identifier.
[0048] S120: Determine a spatial relationship associated with the uplink control channel corresponding to the transmission indication information during repeated transmission.
[0049] After the transmission indication information is obtained, this step can determine the spatial relationship associated with the uplink control channel based on the transmission indication information. The determination method is based on the content included in the transmission indication information and is not limited here.
[0050] The present application may also determine the spatial relationship associated with the uplink control channel included in the transmission indication information and the repeated transmission or frequency hopping configuration.
[0051] The present application provides a configuration method, which effectively configures the spatial relationship in uplink control channel transmission by transmitting indication information.
[0052] Based on the above embodiment, a modified embodiment of the above embodiment is proposed. It should be noted that, in order to simplify the description, only the differences from the above embodiment are described in the modified embodiment.
[0053] In one embodiment, the transmission indication information includes one or more of radio resource control (RRC) signaling, media access control-control element, and downlink control information, and the uplink control channel includes a physical uplink control channel.
[0054] In one embodiment, determining the spatial relationship associated with the uplink control channel corresponding to the transmission indication information during repeated transmission includes one or more of the following:
[0055] Determining one or more spatial relationships associated with uplink transmission according to one or more states of activation of a physical uplink control channel (PUCCH) resource by a media access control-control element included in the transmission indication information, and the PUCCH resource used for uplink control channel transmission indicated by the downlink control information;
[0056] Determining one or more spatial relationships associated with uplink transmission according to the group identification information of the media access control-control element activation included in the transmission indication information and the PUCCH resource used for uplink control channel transmission indicated by the downlink control information;
[0057] The group identification information is identification information of a group formed by grouping high-level parameters indicating spatial relationships. The grouping method is not limited here, and a group may include one or more spatial relationships.
[0058] In this example, the spatial relationship associated with the uplink control channel during repeated transmission may be determined based on the PUCCH resources used for uplink control channel transmission indicated by the downlink control information and one or more activation states of the media access control-control element. The one or more activation states of the media access control-control element may be considered as the states of the one or more activated spatial relationships.
[0059] This example may also determine one or more spatial relationships associated with uplink transmission based on the PUCCH used for uplink control channel transmission indicated by the downlink control information and the group identification information activated by the media access control-control element. The activated group identification information may be used to determine the activated one or more spatial relationships.
[0060] In one embodiment, when the uplink control channel is associated with at least two spatial relationships during repeated transmission and time slot hopping or no frequency hopping is configured, the matching method of the spatial relationship during repeated transmission of the uplink control channel is determined according to the actual transmission timing index.
[0061] The actual transmission timing index may be an index of an actual transmission timing during repeated transmission, that is, a relative index.
[0062] In one embodiment, the starting spatial relationship of the uplink control channels in the group of even time slots is the same as the starting spatial relationship of the uplink control channels in the group of odd time slots, and the spatial relationship within each group is based on the actual transmission opportunity index sequence or cyclic matching.
[0063] In one embodiment, when the number of the associated spatial relationships is two, the starting spatial relationship of the uplink control channels in the group where the even time slots are located is different from the starting spatial relationship of the uplink control channels in the group where the odd time slots are located, including:
[0064] The starting spatial relationship of the uplink control channels grouped in the even time slots is the first spatial relationship, and the starting spatial relationship of the uplink control channels grouped in the odd time slots is the second spatial relationship; or, the starting spatial relationship of the uplink control channels grouped in the even time slots is the second spatial relationship, and the starting spatial relationship of the uplink control channels grouped in the odd time slots is the first spatial relationship.
[0065] The “first” and “second” in the first spatial relationship and the second spatial relationship are only used to distinguish the spatial relationships.
[0066] In the sequential matching method, the first spatial relationship and the second spatial relationship are grouped together, such as: 11221122...; in the cyclic matching method, the first and second spatial relationships are cyclically used between groups, such as: 12121212.... "1" represents the first spatial relationship, and "2" represents the second spatial relationship.
[0067] In one embodiment, the starting spatial relationship of the uplink control channels in the group of even time slots is different from the starting spatial relationship of the uplink control channels in the group of odd time slots, and the spatial relationship within each group is based on the actual transmission opportunity index sequence or cyclic matching.
[0068] In one embodiment, when the number of the associated spatial relationships is two, the starting spatial relationship of the uplink control channels in the group where the even time slots are located is the same as the starting spatial relationship of the uplink control channels in the group where the odd time slots are located, including:
[0069] The starting spatial relationship of the uplink control channels grouped in the even time slots and the odd time slots is the first spatial relationship; or the starting spatial relationship of the uplink control channels grouped in the even time slots and the odd time slots is the second spatial relationship.
[0070] In one embodiment, the number of transmissions for different spatial relationships is the same, which is the sum of the number of transmissions for the same spatial relationship in the group located in the even time slot and the group located in the odd time slot.
[0071] In the case where the spatial relationship is determined based on the actual transmission opportunity index, the number of transmissions of different spatial relationships in the spatial relationships included in the odd-numbered time slots and the even-numbered time slots for repeated transmission is the same.
[0072] In one embodiment, when the uplink control channel is repeatedly transmitted N+M times (N times on even time slots and M times on odd time slots) and the number of associated spatial relationships is two, the number of transmissions of the first spatial relationship in the group where the even time slots are located is The number of transmissions of the second spatial relationship is The number of transmissions of the first spatial relationship in the group at the odd time slot is The number of transmissions of the second spatial relationship is N and M are positive integers.
[0073] In one embodiment, when the uplink control channel is repeatedly transmitted N+M times (N times on even time slots and M times on odd time slots) and the number of associated spatial relationships is two, the number of transmissions of the first spatial relationship in the group where the even time slots are located is The number of transmissions of the second spatial relationship is The number of transmissions of the first spatial relationship in the group at the odd time slot is The number of transmissions of the second spatial relationship is N and M are positive integers.
[0074] In one embodiment, when the uplink control channel is associated with at least two spatial relationships and inter-slot frequency hopping or no frequency hopping is configured, a matching method of the spatial relationship associated with the uplink control channel during repeated transmission is determined based on an absolute time slot index.
[0075] The absolute time slot index can be considered as an index determined by sequentially sorting subsequent time slots based on the initial PUCCH transmission time slot. When determining the spatial relationship matching method, it can be determined based on the absolute time slot index.
[0076] In one embodiment, even time slots and odd time slots correspond to different spatial relationships associated with the uplink control channel.
[0077] In this embodiment, the spatial relationships corresponding to even-numbered time slots and odd-numbered time slots are different.
[0078] In one embodiment, when the number of the associated spatial relationships is two, the even time slots and the odd time slots respectively correspond to different spatial relationships associated with the uplink control channel, including:
[0079] The first spatial relationship is associated with the even time slots and the second spatial relationship is associated with the odd time slots, or,
[0080] The second spatial relationship is associated with the even-numbered time slots, and the first spatial relationship is associated with the odd-numbered time slots.
[0081] In one embodiment, determining the spatial relationship associated with the uplink control channel according to the absolute time slot index includes:
[0082] Starting from the starting transmission time slot, the transmission time slots are grouped, each group contains M time slots, M is greater than or equal to 2;
[0083] The even-numbered groups correspond to the first spatial relationship, and the odd-numbered groups correspond to the second spatial relationship; or,
[0084] The even-numbered groups correspond to the second spatial relationship, and the odd-numbered groups correspond to the first spatial relationship.
[0085] The starting transmission time slot may be considered as the time slot at which repeated transmission of the PUCCH begins. The transmission time slot may be considered as all time slots from the starting transmission to the last transmission time slot.
[0086] After the transmission time slots are grouped, each group can be assigned a different number, and odd-numbered groups and even-numbered groups can correspond to different spatial relationships. In one embodiment, the number of repetitions of the uplink control channel is semi-statically indicated by a higher-layer parameter; or dynamically indicated by downlink control signaling; or dynamically indicated by a combination of higher-layer parameters and downlink control signaling.
[0087] In one embodiment, when the high-layer parameter indicates that the number of repetitions is 1, and the sum of the starting symbol position S, the transmission interval K, and 2 times the duration L of the uplink control channel is less than or equal to the timeslot symbol length, the uplink control channel is repeatedly transmitted within the timeslot;
[0088] When the high-layer parameter indicates that the number of repetitions is 1, and the sum of the starting symbol position S, the transmission interval K, and 2 times the duration L of the uplink control channel is greater than the timeslot symbol length, the uplink control channel is not repeatedly transmitted;
[0089] When the high-layer parameter indicates that the number of repetitions is greater than or equal to 2, the uplink control channel is repeatedly sent between time slots;
[0090] The transmission interval is the symbol interval between two PUCCH repetition transmissions, which is semi-statically indicated by high-level parameters or dynamically indicated by downlink control signaling. If the transmission interval is not indicated, the transmission interval is taken as the set value. If there is no such indication, the transmission interval can take the default value K=0.
[0091] The number of repetitions of the uplink control channel may also be indicated jointly by higher layer parameters and downlink control signaling.
[0092] In one embodiment, when the high-layer parameter indicates that the number of repetitions is 1, and the downlink control signaling indicates that the number of repetitions of the uplink control channel is 1, the uplink control channel is not repeatedly sent;
[0093] When the high-layer parameter indicates that the number of repetitions is 1 and the downlink control signaling indicates that the number of repetitions of the uplink control channel is 2, the uplink control channel is repeatedly sent within the timeslot;
[0094] When the number of repetitions indicated by the higher layer parameters is not 1 or the number of repetitions of the uplink control channel indicated by the downlink control signaling is not 1 or 2, the uplink control channel is repeatedly sent between time slots, and the number of repetitions of the uplink control channel is indicated by the higher layer parameters or downlink control signaling.
[0095] The number of repetitions of the uplink control channel may be indicated only through downlink control signaling.
[0096] In one embodiment, when the downlink control signaling indicates that the number of repetitions is 1, and the sum of the starting symbol position S, the transmission interval K, and 2 times the duration L of the uplink control channel is less than or equal to the timeslot symbol length, the uplink control channel is repeatedly transmitted within the timeslot;
[0097] When the downlink control signaling indicates that the number of repetitions is 1, and the sum of the starting symbol position S, the transmission interval K, and the duration L of the uplink control channel is greater than the time slot symbol length, the uplink control channel is not repeatedly transmitted;
[0098] When the downlink control signaling value is greater than or equal to 2, the uplink control channel is repeatedly sent between time slots;
[0099] The transmission interval is the symbol interval between two PUCCH repetition transmissions, which is semi-statically indicated by a higher layer parameter or dynamically indicated by a downlink control signaling. If there is no such indication, a default value K=0 may be used.
[0100] The number of repetitions of the uplink control channel may be semi-statically indicated by a higher layer parameter, may be dynamically indicated by a downlink control signaling, or may be jointly dynamically indicated by a higher layer parameter and a downlink control signaling.
[0101] In one embodiment, when frequency hopping is configured within a timeslot of the uplink control channel and repeated transmission is performed within the timeslot, frequency hopping is performed within the uplink control channel.
[0102] Frequency hopping in the uplink control channel can be considered that the transmission of one uplink control channel corresponds to two frequency hopping units, each frequency hopping unit corresponds to a different symbol, and each frequency hopping unit corresponds to a different frequency domain resource.
[0103] In one embodiment, when frequency hopping is configured within a time slot for an uplink control channel and repeated transmission is performed within a time slot, frequency hopping is performed between the uplink control channels.
[0104] When frequency hopping is performed between uplink control channels, it can be considered that the transmission of one uplink control channel corresponds to one frequency hopping unit, and each frequency hopping unit corresponds to different frequency domain resources.
[0105] In one embodiment, when frequency hopping within a time slot of the uplink control channel is configured and repeated transmission is performed between time slots, the unit for spatial relationship matching may be a frequency hopping unit or a time slot.
[0106] In the case of frequency hopping within the uplink control channel and repeated transmission between time slots, different frequency hopping units can be associated with different spatial relationships, or,
[0107] Different time slots can be associated with different spatial relationships.
[0108] In an exemplary embodiment, the present application also provides a configuration method, Figure 2 This is a flowchart of another configuration method provided in an embodiment of the present application. This method can be applied to configuring the spatial relationship associated with repeated transmission of an uplink control channel. The configuration method can be performed by a configuration device, which can be implemented by software and / or hardware and is generally integrated on a second communication node, which can be a base station. For details not yet provided in this embodiment, please refer to the above embodiments.
[0109] like Figure 2 As shown, the configuration method provided in this example includes the following steps:
[0110] S210. Determine transmission indication information, where the transmission indication information indicates a spatial relationship associated with an uplink control channel during repeated transmission.
[0111] The second communication node may determine the specific content of the transmission indication information based on the spatial relationship associated with the transmitted uplink control channel. The specific content of the transmission indication information is not limited herein. The transmission indication information may indicate one or more spatial relationships associated with the uplink control channel during repeated transmission. The indication method may be through state activation or activation through group identification information.
[0112] S220: Transmit the transmission instruction information.
[0113] After the transmission indication information is determined, this step may transmit the determined transmission indication information to the corresponding first communication node.
[0114] The configuration method provided in the present application effectively configures the spatial relationship associated with the first communication node when performing uplink control channel transmission through determined transmission indication information.
[0115] Based on the above embodiment, a modified embodiment of the above embodiment is proposed. It should be noted that, in order to simplify the description, only the differences from the above embodiment are described in the modified embodiment.

[0120] The starting spatial relationship of the uplink control channels in the group where the even time slots are located is different from the starting spatial relationship of the uplink control channels in the group where the odd time slots are located. The spatial relationship within each group is based on the actual transmission opportunity index sequence or cyclic matching;
[0121] In one embodiment, when the number of the associated spatial relationships is two, the starting spatial relationship of the uplink control channels in the group where the even time slots are located is the same as the starting spatial relationship of the uplink control channels in the group where the odd time slots are located, including:

[0125] In one embodiment, the number of transmissions for different spatial relationships is the same, which is the sum of the number of transmissions for the same spatial relationship in the group located in the even time slot and the group located in the odd time slot.
[0126] In one embodiment, when the uplink control channel is repeatedly transmitted N+M times and the number of associated spatial relationships is two, the number of transmissions of the first spatial relationship in the group in the even time slot is The number of transmissions of the second spatial relationship is The number of transmissions of the first spatial relationship in the group at the odd time slot is The number of transmissions of the second spatial relationship is The number of transmissions in even time slots is N, and the number of transmissions in odd time slots is M, where N and M are positive integers.

[0154] In one embodiment, when frequency hopping within the uplink control channel time slot is configured and repeated transmission is performed within the time slot, frequency hopping is performed within the uplink control channel; or, when frequency hopping within the uplink control channel time slot is configured and repeated transmission is performed within the time slot, frequency hopping is performed between the uplink control channels.
[0155] In one embodiment, when frequency hopping within a time slot of the uplink control channel is configured and repeated transmission is performed between time slots, the unit for spatial relationship matching may be a frequency hopping unit or a time slot.
[0156] The following is an exemplary description of the present application. The configuration method provided by the present application can be considered as an uplink channel transmission enhancement method. The present application is an enhancement of the reliability of uplink information transmission in Multi-TRP or Multi panel. The present application provides a method for using multi-beam transmission of PUCCH indicated by DCI; a method for matching beams when the indicated PUCCH resource is associated with two spatial relations when repeated transmission between PUCCH time slots and inter-slot Frequency Hopping is configured; a method for indicating repeated transmission within a PUCCH time slot; and a frequency hopping method for repeated transmission within a time slot when intra-slot Frequency Hopping is used.
[0157] Example 1. This example illustrates the method of using multi-beam transmission for the PUCCH indicated by the DCI. Specifically:
[0158] In R15, on each BWP, PUCCH can be configured with up to 8 high-level parameters PUCCH-SpatialRelationInfo, such parameters include beam-related referenceSignal, power control-related parameters pucch-PathlossReferenceRS-Id, p0-PUCCH-Id, closedLoopIndex. And it is indicated by Media Access Control-Control Element (MAC-CE) signaling. MAC-CE signaling includes the bitmap of PUCCH-SpatialRelationInfo. Figure 2aA schematic diagram of a bitmap provided for an embodiment of the present application. The length of the bitmap 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 information (PUCCH spatial-relation) corresponding to PUCCH-SpatialRelationInfoId i is activated, and the UE can use the corresponding beam to send PUCCH. 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.
[0159] In order to realize the multi-beam transmission mode of PUCCH repetition, the following two methods are considered. The relationship between the beam and the space, that is, the spatial relation, described in this application is a one-to-one correspondence.
[0160] Method 1: Allow two PUCCH spatial relations to be activated at the same time, so that one PUCCH resource can be associated with two beams.
[0161] Method 2: Based on the eight PUCCH high-level parameters PUCCH-SpatialRelationInfo configured in the activated BWP, these eight PUCCH-SpatialRelationInfo are paired to generate n new PUCCH-SpatialRelationInfo groups. Table 1 shows a spatial relationship grouping method provided in an embodiment of the present application. The grouping results can be found in Table 1, but this method is not limited to this method.
[0162] Table 1 A grouping method of spatial relationships provided in the embodiment of the present application
[0163]
[0164] Taking the grouping method in Table 1 as an example, when MAC-CE activates S11 for the UE, the UE's transmit beam is determined by S1 and S2 of the initially configured PUCCH-SpatialRelationInfo.
[0165] When the base station associates two spatial relations with the PUCCH resources indicated to the UE through DCI, the UE can use two beams for uplink transmission.
[0166] Example 2. This example illustrates a method for matching beams based on relative indices when PUCCH is repeatedly transmitted between time slots and inter-slot frequency hopping (i.e., inter-slot Frequency Hopping) is configured, and the indicated PUCCH resources are associated with two spatial relationships.
[0167] To further improve PUCCH coverage, NR supports repeated transmission of PUCCH, i.e., multi-slot PUCCH aggregation, and the number of repeated transmissions can be configured by high-level signaling. In multi-slot PUCCH, in order to obtain frequency scalability gain, PUCCH frequency hopping between time slots is additionally introduced. Figure 2b A schematic diagram of a configuration of inter-slot frequency modulation provided in an embodiment of the present application is provided. Figure 2b If inter-slot frequency hopping is configured, the configuration of the PRB index of the first hopping unit (indicated by startingPRB) is applied to the even slot indices in the multi-slot PUCCH, and the configuration of the PRB index of the second hopping unit (indicated by secondHopPRB) is applied to the odd slot indices in the multi-slot PUCCH.
[0168] When the PUCCH resources indicated by the base station are associated with multiple beams and inter-slot frequency hopping is configured, a method for allocating PUCCH beams according to the index of the actual transmission opportunity.
[0169] Method 1: Figure 2c A schematic diagram of a configuration method of a spatial relationship provided in an embodiment of the present application is provided. Figure 2c All time slots that meet the PUCCH transmission conditions are grouped. Even-numbered time slots are group 0, corresponding to the frequency domain resources indicated by the startingPRB. Odd-numbered time slots are group 1, corresponding to the frequency domain resources indicated by the secondHopPRB. The same starting beam is used for rotation within groups 0 and 1. For example, when the indicated PUCCH resources are associated with spatial relations 0 and 1, they correspond to beams 0 and 1. Sequential or cyclic matching of beams is performed within groups 0 and 1.
[0170] Attachment Figure 2c Time slots 0, 2, 6, 8, and 10 are group 0, and time slots 3, 7, and 9 are group 1. Figure 2c The upper part is the beam cycle matching. In group 0 and group 1, the beam cycle mode is: beam 0, beam 1, beam 0, beam 1...; Figure 2c The lower half of the is the beam order matching. In group 0 and group 1, the beam cycle is: beam 0, beam 0, beam 1 beam 1, ...
[0171] Method 2: Figure 2dA schematic diagram of another configuration mode of spatial relationship provided in the embodiment of the present application is shown in FIG. Figure 2d All time slots that meet the PUCCH transmission conditions are grouped. Even-numbered time slots are group 0, corresponding to the frequency domain resources indicated by the startingPRB, and odd-numbered time slots are group 1, corresponding to the frequency domain resources indicated by the secondHopPRB. Different starting beams are used for cycling within groups 0 and 1, respectively. For example, when the indicated PUCCH resources are associated with spatial relations 0 and 1, they correspond to beams 0 and 1.
[0172] Attachment Figure 2d Time slots 0, 2, 6, 8, and 10 are group 0, and time slots 3, 7, and 9 are group 1. Figure 2d The upper part is the beam cycle matching. The beam cycle mode of group 0 is: beam 0, beam 1, beam 0, beam 1... The beam cycle mode of group 1 is: beam 1, beam 0, beam 1, beam 0...; Figure 2d The lower half of the is the beam order matching. The beam cycle of group 0 is: beam 0, beam 0, beam 1, beam 1, ..., and the beam cycle of group 1 is: beam 1, beam 1, beam 0, beam 0, ...
[0173] Method 3: Based on the grouping of method 1 or 2, limit the number of different beams in group 0 and group 1: divide the N transmissions corresponding to group 0 into two parts, and the number of transmissions corresponding to beam 0 is The number of transmissions corresponding to beam 1 is The M transmissions corresponding to group 1 are also divided into two parts, and the number of transmissions corresponding to beam 0 is The number of transmissions corresponding to beam 1 is
[0174] Figure 2e This is another schematic diagram of a spatial relationship configuration method provided in the embodiment of the present application, see Figure 2e , time slots 0, 2, 6, 8, and 10 are group 0, and time slots 3, 7, and 9 are group 1. According to the above calculation method, there are 2 transmissions in group 0 using beam 0 and 3 transmissions using beam 1; there are 2 transmissions in group 1 using beam 0 and 1 transmission using beam 1. Figure 2e The beam matching method in the group matching method is group matching, that is, group 0 The transmission uses beam 0, and the remaining The second transmission uses beam 1; group 1 The transmission uses beam 1, and the remaining The second transmission uses beam 0. The matching method is not limited to the above method, and the cyclic matching or sequential matching in method 2 may also be used.
[0175] Example 3: This example is used to illustrate a method for matching beams based on absolute indexes when PUCCH is repeatedly transmitted between time slots and inter-slot frequency hopping (i.e., inter-slot Frequency Hopping) is configured, and the indicated PUCCH resources are associated with two spatial relationships.
[0176] In R15, the introduced inter-slot PUCCH frequency hopping is indicated based on the absolute index. The benefit of this is to ensure that multiple UEs served by the same base station do not collide in the frequency domain. Therefore, it should also be considered to allocate beams based on the absolute index to avoid beam collision problems of different UEs.
[0177] This example is used to illustrate the method of allocating PUCCH beams based on absolute time slot indices when the PUCCH resources indicated by the base station are associated with multiple beams and inter-time slot hopping is configured.
[0178] Method 1: Figure 2f This is another schematic diagram of a spatial relationship configuration method provided in the embodiment of the present application, see Figure 2f , associating beams with frequency hopping indicators. Even-numbered time slots and odd-numbered time slots correspond to multiple beams associated with PUCCH resources. For example, when the indicated PUCCH resources are associated with spatial relations 0 and 1, beams 0 and 1 are associated. Beam 0 is applied to the time slot indicated by the startingPRB, and beam 1 is applied to the time slot indicated by the secondHopPRB.
[0179] Attachment Figure 2f The even-numbered time slots used to transmit PUCCH include time slots 0, 2, 6, 8, and 10, corresponding to the use of beam 0; the odd-numbered time slots used to transmit PUCCH include time slots 3, 7, and 9, corresponding to the use of beam 1.
[0180] Method 2: Figure 2g This is another schematic diagram of a spatial relationship configuration method provided in the embodiment of the present application, see Figure 2g , starting from the initial transmission time slot, the subsequent time slots are grouped:
[0181] Each group contains M time slots (M is greater than or equal to 2). Even-numbered groups are sent using beam 0, and odd-numbered groups are sent using beam 1.
[0182] Take M=2 as an example:
[0183] The first group is time slot 0 1, sent using beam 0;
[0184] The second group is time slots 2 and 3, transmitted using beam 1;
[0185] The third group is time slots 4 and 5, transmitted using beam 0;
[0186] The fourth group is time slots 6 and 7, and is sent using beam 1.
[0187] Take the repetition number of 8 times as an example, as shown in the attached Figure 2g shown.
[0188] Example 4, this example is used to illustrate a method for indicating repeated transmission within a PUCCH time slot.
[0189] To implement repeated PUCCH transmission within a timeslot, a transmission interval K (the symbol interval between two transmissions) must be specified by higher layers. If this parameter is not configured, K defaults to 0. The base station indicates the PUCCH resource to the UE via the PUCCH resource indicator (PRI) field in the DCI, including the PUCCH starting symbol position (S) and duration (L).
[0190] The UE can determine whether it is an inter-slot repetition or an intra-slot repetition based on the above information and the indicated number of repetitions. The determination method is as follows:
[0191] Method 1: The number of PUCCH repetitions is only semi-statically indicated by the higher-layer parameter nrofslots
[0192] 1. When nrofslots=1
[0193] The UE determines the relationship between the starting symbol position (S), duration (L) and transmission interval K of the PUCCH indicated by the PRI. The value range of S is 0 to 13.
[0194] Figure 2h A schematic diagram of determining a PUCCH transmission method provided in an embodiment of the present application is provided. Figure 2i A schematic diagram of another PUCCH transmission method determination provided in an embodiment of the present application is provided. When S+L+K+L is less than or equal to 13, the UE performs repeated transmission within the time slot, as shown in the attached figure. Figure 2h shown.
[0195] When S+L+K+L is greater than 13, the UE does not repeat the transmission. Figure 2i shown.
[0196] 2. When nrofslots is greater than or equal to 2
[0197] The UE repeatedly transmits the PUCCH between time slots according to the starting symbol position (S) and duration (L) of the PUCCH indicated by the PRI.
[0198] Method 2: Semi-static indication
[0199] The number of PUCCH repetitions is jointly indicated by the high-level parameter nrofslots and DCI. In R16, the number of repeated transmissions of PUCCH is semi-statically indicated by the high-level parameter. However, when the channel state changes rapidly, the indicated number of repetitions may not be consistent with the current channel conditions. Therefore, this application introduces a method for DCI to dynamically indicate the number of PUCCH repetitions.
[0200] 1. Semi-static parameter nrofslot = 1, dynamic DCI indication is repeated twice
[0201] The UE performs repeated transmission within the time slot, similar to the case where S+L+K+L is less than or equal to 13 in method 1.
[0202] 2. Semi-static parameter nrofslot = 1, dynamic DCI indication is repeated once
[0203] The UE does not perform retransmission.
[0204] 3. Other indications except 1 and 2
[0205] The UE repeatedly transmits the PUCCH between time slots according to the starting symbol position (S) and duration (L) of the PUCCH indicated by the PRI.
[0206] Example 5: This example is used to illustrate the problem of repeated transmission within a time slot when frequency hopping within a PUCCH time slot (i.e., intra-slot Frequency Hopping) is performed.
[0207] In LTE, all PUCCH formats must support frequency hopping to obtain frequency hopping gain. However, in NR, considering the flexibility of system design, the frequency modulation of all PUCCH formats greater than or equal to 2 symbols is configurable. For a PUCCH with a length of N orthogonal frequency division multiplex (OFDM) symbols, if intra-slot frequency hopping is configured, the number of OFDM symbols in the first hopping unit is The configuration of the PRB index is indicated by startingPRB; the number of OFDM symbols in the second hopping unit is The configuration of the PRB index is indicated by secondPRB.
[0208] Figure 2j A schematic diagram of a PUCCH transmission method provided in an embodiment of the present application is provided. Figure 2k A schematic diagram of another PUCCH transmission method provided in an embodiment of the present application is provided. When the UE is instructed to repeatedly transmit within a PUCCH timeslot, the frequency hopping method within the timeslot considers the following two methods:
[0209] Method 1: For a PUCCH with a length of N OFDM symbols, it is transmitted twice in a time slot. Each transmission corresponds to two frequency hopping units. 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 hopping unit is The configuration of the PRB index is indicated by secondPRB, such as Figure 2j shown.
[0210] Method 2: For a PUCCH with a length of N OFDM symbols, it is transmitted twice in a time slot. Each transmission corresponds to a frequency hopping unit. The number of OFDM symbols in the first frequency hopping unit is N, and the PRB index configuration is indicated by startingPRB; the number of OFDM symbols in the second frequency hopping unit is also N, and the PRB index configuration is indicated by secondPRB, such as Figure 2k shown.

[0213] Based on the above embodiment, a modified embodiment of the above embodiment is proposed. It should be noted that, in order to simplify the description, only the differences from the above embodiment are described in the modified embodiment.
