[0147] Multiple frequency domain bandwidths in the frequency domain bandwidth group share a TCI state mapping table, including that the same TCI state index in the TCI mapping table corresponds to different TCI state lists in different frequency domain bandwidths, or that the quasi-co-site reference signal of the first type of quasi-co-site parameters associated with the same TCI state index in the TCI mapping table corresponds in each frequency domain bandwidth to the reference signal in the frequency domain bandwidth, and the reference signal resource indexes corresponding to the reference signals in different frequency domain bandwidths differ by a predetermined value, and the predetermined value is an integer.

[0148] In an exemplary embodiment, the invention is characterized by comprising at least one of the following:

[0149] The difference set of the set of TCI states included in the TCI state lists of different frequency domain bandwidths in the frequency domain bandwidth group is empty;

[0150] The intersection of the sets of TCI states included in the TCI state lists of different frequency domain bandwidths in the frequency domain bandwidth group is not empty;

[0151] The TCI state included in the predetermined TCI state list belongs to a set of TCI states included in the TCI state list in each frequency domain bandwidth of the group in the frequency domain bandwidth, wherein the frequency domain bandwidth index corresponding to the predetermined TCI state list is included in the MAC-CE signaling for updating or activating the TCI state mapping table.

[0152] In an exemplary embodiment, the first type of quasi co-location parameters includes at least one of the following: Doppler shift, Doppler spread, average delay, delay spread, spatial reception parameters, and average gain.

[0153] In an embodiment of an example, for the configuration of the TCI state of the DMRS of the downlink physical shared channel PDSCH in a BWP, a three-layer signaling structure is adopted, that is, RRC signaling configures a TCI state list in each BWP, and a TCI state list includes one or more TCI states. Then, the corresponding TCI state is activated for up to X code points (code point) in each BWP through MAC-CE signaling, where MAC-CE signaling activates up to Y TCI states for one code point. Among them, X is the maximum number of state values ​​corresponding to the bit field (such as TCI bit field) indicating quasi-co-location information in DCI, and one code point corresponds to a bit field value of the TCI field in the DCI.

[0154] Table 2 is a list of the correspondence between code points and TCI states provided by this application. As shown in Table 2, the TCI field in DCI is 3 bits, and MAC-CE activates the corresponding TCI state for 8 code points. In Table 2, X=8, Y=2. This application only describes the values ​​of X and Y, not the selection.

[0155] Table 2

[0156] The value of the code point in DCI TCI state activated by MAC-CE 000 TCI state18 001 TCI state3, TCI state4 010 TCI state5 011 TCI state6 100 TCI state7 101 TCI state 23, TCI state 58 110 TCI state44 111 TCI state127

[0157] In this way, in CA mode, it is necessary to configure a TCI state list for each BWP in each CC, and it is also necessary to use a MAC-CE signaling activation code point corresponding to each BWP of each CC. For example, the TCI states corresponding to all code points in the 8 code points in Table 2 constitute the TCI state set. This will result in a very large signaling overhead, and multiple MC-CE signaling is involved, and the signaling delay is also relatively large.

[0158] On the other hand, TCI state is related to the transmit beam. Different TCI states can represent different transmit beams. The transmit beams of multiple CCs are generally consistent. Therefore, one MAC-CE signaling can be used to activate the same TCI state set for multiple CCs, that is, a TCI state mapping table, so that each BWP in multiple CCs can share a TCI state mapping table corresponding to the same MAC-CE signaling, that is, the MAC-CE signaling is the same for all CC selected beams. However, there is a problem that the quasi-co-located reference signal of the target channel and / or signal spatial reception parameter Spatial Rx parameter, Doppler shift, and average delay in a CC can be located in other CCs, but the quasi-co-located reference signal associated with Doppler spread Doppler spread cannot be located in other CCs. Therefore, when a MAC-CE signaling activates the same TCI state set for multiple BWPs, where these multiple BWPs belong to one CC or multiple CCs, as shown in Table 2, a set of MAC-CE signaling activates the TCI shown in Table 2 for each BWP in the multiple BWP activations. The state mapping table also activates the mapping relationship between code points and TCI states shown in Table 2.

[0159] Table 2 is referred to as the TCI state mapping table in this application, and the code point corresponding to the PDSCH in each of the multiple BWPs and the TCI state mapping table of the TCI state are shown in Table 2. In the set of MAC-CE signaling, only the various TCI state indexes in Table 2 are activated, and the TCI state index corresponding to the TCI state index corresponds to the TCI state list in each CC or BWP with the TCI state index.

[0160] Specifically, Figure 2 : is a schematic diagram of a TCI state list of multiple RRC configurations of multiple CCs corresponding to MAC-CE signaling provided by this application. Figure 2 As shown, a set of MAC-CE signaling corresponds to the frequency domain bandwidth group {CC1, CC2, CC3}, and a set of MAC-CE signaling activates the TCI state mapping table of the code point and TCI state shown in Table 2. The set of MAC-CE signaling includes one or more MAC-CE signaling, and the multiple MAC-CE signaling is because the number of TCI states corresponding to one code point is greater than 1. However, the referenced TCI state mapping table of the PDSCH in each CC is to map Table 2 to the TCI state list configured in each BWP or CC corresponding to the TCI state corresponding to the TCI state index. Table 3 is the TCI state mapping table of the PDSCH in CC1 provided by this application. For example, the TCI state mapping table of the PDSCH in CC1 is TCIstate is in TCI state list 1.

[0161] Table 3

[0162]

[0163] Table 4 is a TCI state mapping table of PDSCH in CC2 provided by the present application. For example, the TCI state mapping table of PDSCH in CC2 is TCI state in TCI state list 1.

[0164] Table 4

[0165]

[0166] Table 5 is a TCI state mapping table of PDSCH in CC3 provided by the present application. For example, the TCI state mapping table of PDSCH in CC3 is TCI state in TCI state list 1.

[0167] Table 5

[0168]

[0169]

[0170] It can be seen from Tables 3 to 5 that when the frequency domain bandwidth group {CC1, CC2, CC3} shares a set of MAC-CE signaling, the MAC-CE signaling only indicates the index of the TCI state. The TCI state list from which this TCI state index comes depends on the TCI state list configured in the BWP or CC where the PDSCH is located.

[0171] Figure 2 is a schematic diagram of a TCI state mapping table of the same code point to TCI state index provided by this application, such as Figure 2 As shown, a MAC-CE signaling activates a TCIstate mapping table of the same code point to TCI state index for multiple frequency domain bandwidths, and the TCI state list to which the TCI state corresponding to the TCI state index belongs is the TCI state list configured in the frequency domain bandwidth where the PDSCH is located.

[0172] Figure 3 is a schematic diagram of a TCI state mapping table of the same code point to TCI state index provided by this application, such as Figure 3 As shown, another way for multiple frequency domain bandwidths to share a set of MAC-CE signaling is shown. The TCI state index activated in the MAC-CE command corresponds to the TCI state list in the predetermined CC. For example, MAC-CE activates the TCI state mapping table shown in Table 2. The TCI state corresponding to the TCI state index in Table 2 comes from TCI state list 1. {CC2, CC3} also obtains the TCI state mapping table with reference to Table 2. However, the TCI state list is not configured in the high-level signaling of CC2 and CC3. Instead, the TCI state mapping table in {CC2, CC3} is obtained according to the QCL-RS included in each TCI state in TCI state list 1.

[0173] For example, the QCL-RS corresponding to each code point of each CC in {CC2, CC3} belongs to this CC, that is, CC2 or CC3, and there is a corresponding relationship between the QCL-RS and the QCL-RS resource of the code point in CC1, for example, the QCL-RS corresponding to the same code point in each frequency domain bandwidth are of the same type, the resource index is the same, or there is a predetermined deviation in the resource index. For example, MAC-CE activates the TCI state mapping table shown in Table 2, and the TCI state index in Table 2 is the TCIstate index in TCI state list 1. The TCI state mapping table referenced by the PDSCH in CC2 is obtained according to the following method: first, the TCI state is obtained in TCI state list 1 according to the TCI state index corresponding to each code point in Table 2, and the quasi-co-sited reference signal 2 corresponding to the codepoint in CC2 is obtained according to the quasi-co-sited reference signal 1 included in the TCI state. The quasi-co-sited reference signal 1 is in CC1, and the quasi-co-sited reference signal 2 is in CC2, except that the resource indexes of the quasi-co-sited reference signal 1 and the quasi-co-sited reference signal 2 are the same, or the difference in resource index is a predetermined value.

[0174] Table 6 is a correspondence table of TCI state index, quasi co-location reference signal, and quasi co-location parameter provided by the present application, and Table 7 is a correspondence table of TCI state index, quasi co-location reference signal, and quasi co-location parameter provided by the present application. For example, TCI state 18 is configured in TCIstate list 1 as shown in Table 6, and the quasi co-location reference signal in Table 6 belongs to CC1, then the quasi co-location reference signal corresponding to codepoint '000' in CC2 is shown in Table 7, wherein CSI-RS25 in Table 7 belongs to CC2, and CSI-RS25 in Table 6 belongs to CC1, and SSB23 in Table 6 and Table 7 may belong to CC1 and CC2 respectively, or may be just SSB23 in CC1, because the target channel and / or signal and the QCL-RS regarding QCL-Type D may be located in different CCs.

[0175] Table 6

[0176]

[0177] Table 7

[0178]

[0179] The above is that one MAC-CE signaling corresponds to one CC group. After the MAC-CE signaling is updated, the TCI state mapping table between the code point and TCI state of each CC in the CC group is updated accordingly. This article does not exclude the possibility that the TCIstate mapping table corresponds to more than one MAC-CE signaling. For example, the first MAC-CE signaling is used to activate the first TCI state corresponding to the code point, and the second MAC-CE signaling is used to activate the second TCIstate corresponding to the code point. As shown in Table 2, some code points correspond to only one TCI state.

[0180] The above method is a TCI state mapping table between CC shared code points and TCI states in a CC group, and further, the TCI state mapping table is activated by MAC-CE signaling. Further, the quasi-co-site reference signal of the associated QCL-TypeA in the TCI state mapping table and the target channel and / or signal belong to the same frequency domain bandwidth.

[0181] Furthermore, when two CORESET groups are configured in a CC, each CORESET group corresponds to a TCI state mapping table, that is, each CORESET group corresponds to a group of MAC-CE update signaling. The quasi-co-site reference signal of the PDSCH scheduled in each CORESET group refers to the TCI state mapping table corresponding to this CORESET group.

[0182] Figure 4 This is a schematic diagram of a TCI state mapping table corresponding to a PDSCH with the same CORESET group identifier or the same scrambling configuration ID provided by the present application, such as Figure 4 The frequency domain bandwidth groups {CC1, CC2, CC3, CC4} share MAC-CE signaling. Further, the CORESETs with the same CORESET group identifier in the CC group share MAC-CE signaling, wherein the MAC-CE signaling is used to activate or update a TCI state mapping table between a code point and a TCI state, and the PDSCH obtains the TCI state corresponding to the DMRS of the PDSCH with reference to the TCI state mapping table and the code point value notified in the DCI.

[0183] Different CORESET groups in the CC group correspond to different TCI state mapping tables, and the different TCIstate mapping tables are activated or updated by different MAC-CE signaling. At this time, the CORESETs with the same CORESET group identifier in the CC group share MAC-CE signaling, and different CORESET groups correspond to different MAC-CE signaling.

[0184] The different TCI state mapping tables can also be activated or updated by the same MAC-CE signaling. In this case, the CORESETs with the same CORESET group identifier in the CC group share a portion of a MAC-CE signaling corresponding to a mapping table, and different CORESET groups correspond to portions of a MAC-CE signaling corresponding to different mapping tables.

[0185] Figure 5 This is a schematic diagram of a TCI state mapping table corresponding to a PDSCH with the same CORESET group identifier or the same scrambling configuration ID provided by the present application, such as Figure 5 As shown, {CORESET group 11 in CC1, CORESET group 31 in CC3} corresponds to TCI state mapping table 1, and {CORESET group 12 in CC1, CORESET group 32 in CC3} corresponds to TCIstate mapping table 2. Furthermore, CC1 schedules CC2 and CC3, and one BWP in CC2 corresponds to two channel scrambling sequences {scrambling21, scrambling22}. The channel scrambling sequence of the PDSCH in CC2 scheduled by the PDCCH in CC1's CORESET group 1 is generated by scrambling21, and the channel scrambling sequence of the PDSCH in CC2 scheduled by the PDCCH in CC1's CORESET group 2 is generated by scrambling22. For example, if the scrambling sequence of the channel is a PN (pseudo-random) sequence, the initialization value of the PN sequence is obtained by the following formula:

[0186] c init =n RNTI 2 15 +q·2 14 +n ID

[0187] Among them, n RNTI is the RNTI number corresponding to PDSCH, n IDIt is equal to the above scrambling21 or scrambling22. Therefore, the PDSCH scrambled by scrambling21 in CC2 refers to TCI state mapping table 1 to obtain a quasi-co-site reference signal, and the PDSCH scrambled by scrambling22 in CC2 refers to TCI state mapping table 2 to obtain a quasi-co-site reference signal. However, only one scrambling sequence parameter {scrambling41} is configured in CC4, and the PDSCH scrambled by scrambling41 in CC4 corresponds to TCIstate mapping table 1, and the MAC-CE signaling part corresponding to TCI state mapping table 2 is ignored in CC4.

[0188] When using Figure 2 The method of activating or updating MAC-CE signaling of the frequency domain bandwidth group sharing TCI state mapping table shown, for the PDSCH in each CC in {CC1, CC2, CC3, CC4}, the TCI state activated or updated in the two MAC-CE signalings that activate or update the two TCI state mapping tables comes from the same TCI state list configured by RRC signaling, that is, both come from the configured TCI state list i in the CC where the PDSCH is located, i=1,2,3,4, any one of which, where i is the index of the CC where the PDSCH is located, and each CC index corresponds to a TCI state list.

[0189] In an exemplary embodiment, Figure 5 This is a schematic diagram of a TCIstate mapping table corresponding to PDSCHs in multiple CCs provided by this application, such as Figure 5 The PDSCHs with the same CORESET group identifier or the same scrambling configuration ID in the multiple CCs shown correspond to one TCI state mapping table, and the activated TCI states in different TCI mapping tables correspond to different TCI state lists.

[0190] The TCIstate activated or updated in the two MAC-CE signalings of activating or updating the two TCI state mapping tables comes from different TCI state lists configured by RRC signaling, such as Figure 5As shown, the TCI state set in the MAC-CE signaling corresponding to TCI state mapping table 1 belongs to TCI state list i-1, and the TCI state set in the MAC-CE signaling corresponding to TCI state mapping table 2 belongs to TCI state list i-2, that is, RRC signaling configures two TCI state lists for each CC in the CC group, corresponding to different CORESET groups. Or RRC signaling configures two TCIstate lists for a CC group, corresponding to different CORESET groups, and there is no need to configure a TCI state list for each CC in the CC group.

[0191] Figure 6 This is a schematic diagram of a TCI state mapping table determined by a scrambling configuration ID or a CORESET group ID in a CC provided by the present application, such as Figure 6 In the above, only one CORESET group CORESET31 is configured in CC3. When the TCI state mapping table of the shared PDSCH of {CC1, CC2, CC3, CC4} activates or updates the MAC-CE signaling, CC3 ignores the part of the MAC-CE signaling corresponding to the TCI state mapping table 2. Only one channel scrambling parameter scrambling41 is configured in CC4, and CC4 ignores the part of the MAC-CE signaling corresponding to the TCI state mapping table 2.

[0192] Figure 7 This is a schematic diagram of a TCI state mapping table determined by a scrambling configuration ID or a CORESET group ID in a CC provided by the present application, such as Figure 7 In the above, only one CORESET group CORESET32 is configured in CC3, and the part corresponding to TCI state mapping table 1 in the MAC-CE signaling is ignored in CC3. Only one scrambling41 is configured in CC4, and the part corresponding to TCI state mapping table 2 in the MAC-CE signaling is ignored in CC4.

[0193] Figure 8 This is a schematic diagram of a TCI state mapping table determined by a scrambling configuration ID or a CORESET group ID in a CC provided by the present application, such as Figure 8In the above, only one CORESET group CORESET31 is configured in CC3, and the part corresponding to TCI state mapping table 2 in the MAC-CE signaling is ignored in CC3. Only one scrambling42 is configured in CC4, and the part corresponding to TCI state mapping table 1 in the MAC-CE signaling is ignored in CC4.

[0194] In summary, when the frequency domain bandwidth group shares the TCI state mapping table to activate or update the MAC-CE signaling, the number of activated TCI state mapping tables is determined according to the maximum number of CORESET groups included in each CC in the CC group. When there is a CORESET configuration in one CC in the CC group, the TCIstate mapping table corresponding to the CORESET group is determined according to the CORESET group index. When the PDSCH in one CC in the CC group is scheduled across CCs by PDCCHs in other CCs, there is a corresponding relationship between different CORESET groups in the CC where the PDCCH is located and different values ​​of the PDSCH parameters of the CC where the scheduled PDSCH is located. Further, according to the configuration indexes of different values ​​of the same type of parameters of the PDSCH, the TCI state mapping table corresponding to the PDSCH corresponding to the configuration index of the same type of parameter value is determined. If the number of CORESET groups configured in a CC in the CC group is less than the maximum number of CORESET groups, the part of the CORESET group that is not configured in the shared MAC-CE signaling is ignored in this CC. Or when the PDSCH in one of the CCs is cross-CC scheduled by other CCs, and the number of PDSCH parameters (such as scrambling) configured in the CC is less than the number of the maximum CORESET groups, the configuration index of the parameter value of the PDSCH that is not configured in the shared MAC-CE signaling is ignored in this CC. Or when all CORESETs in a frequency domain bandwidth of the frequency domain bandwidth group configure the PDCCH in the CORESET without including the TCI indication field, the activation or update signaling of the mapping table corresponding to the CORESET group is ignored in the frequency domain bandwidth, wherein the CORESET of the one frequency domain bandwidth includes the CORESET located in the frequency domain bandwidth, and may also be the CORESET located in other frequency domain bandwidths that schedules the PDSCH in the frequency domain bandwidth, that is, the PDCCH that schedules the PDSCH and the PDSCH are located in different frequency domain bandwidths.

[0195] In another implementation of the activation or update MAC-CE signaling of the frequency domain bandwidth group sharing the TCI state mapping table, it is required that the number of CORESET groups configured in all frequency domain bandwidths in the frequency domain bandwidth group is the same, for example, all are 1, or all are 2.

[0196] The above CC is configured with or corresponds to one or more values ​​of the same type of parameter, which means that a BWP in the CC is configured with or corresponds to one or more values ​​of the same type of parameter, such as the currently activated BWP. For example, the above CC is configured with or corresponds to one or two scrambling / CORESET groups / TCI state lists, which means that a BWP in the CC is configured with or corresponds to one or two scrambling / CORESET groups / TCI state lists.

[0197] Figures 5 to 8 The same type of parameters of PDSCH described in the specification take the channel scrambling parameter scrambling as an example. Of course, this embodiment does not exclude other parameters of PDSCH, such as one or more of the following parameters: process number set information, demodulation reference signal information, uplink control channel resource group where the HARQ-ACK of PDSCH is located, rate matching information, non-periodic measurement reference signal information, and downlink data channel information of semi-continuous transmission.

[0198] In an exemplary embodiment, the frequency domain bandwidth group shares the activation or update MAC-CE command of the TCI state mapping table, and the maximum number of TCI states activated in the activation MAC-CE command is greater than the maximum number of TCI states allowed to be activated in a frequency domain bandwidth. As shown in the above embodiment, the frequency domain bandwidth group shares the activation or update MAC-CE command of the TCI state mapping table, but as Figure 2 The TCIstate to which the activated TCI state in the MAC-CE command belongs is from each CC, respectively. On the other hand, the TCI state index included in the TCI state list in each CC will be different, and the TCI state is not included in the TCI state list corresponding to a frequency domain bandwidth. For this frequency domain bandwidth, the activation or deactivation indication field corresponding to the TCI state in the shared MAC-CE command is ignored. For example, a MAC-CE command in a frequency domain bandwidth can activate up to X TCI states, and more than X TCI states can be activated in the shared MAC-CE of the frequency domain bandwidth group, but the maximum number of TCI states that can be activated in one frequency domain bandwidth cannot exceed X.

[0199] Specifically, for example, the TCI state list in CC1 includes {TCI state1~TCI state64, TCIstate69~TCI state127}, and the TCI state list in CC1 includes {TCI state1~TCI state68}. The shared MAC-CE command activates: {TCI1, TCI2, TCI5, TCI8, TCI50, TCI65, TCI66, TCI67, TCI100, TCI101, TCI102}. Then, the activated TCI state set corresponding to the activated TCI state mapping table in CC1 is: {TCI1, TCI2, TCI5, TCI8, TCI50, TCI100, TCI101, TCI102}, and the activated TCI state set corresponding to the activated TCI state mapping table in CC2 is {TCI1, TCI2, TCI5, TCI8, TCI50, TCI65, TCI66, TCI67}.

[0200] In a second implementation of this embodiment, the frequency domain bandwidth group shares an activation or update MAC-CE command of a TCI state mapping table, and the maximum number of TCI states activated in the activation MAC-CE command is equal to the maximum number of TCI states allowed to be activated in a frequency domain bandwidth. Furthermore, it is required that the difference set of TCI state indexes included in the list of TCI states activated by RRC signaling in all frequency domain bandwidths in the frequency domain bandwidth group is empty, and the intersection is non-empty.

[0201] In an exemplary embodiment, the greater the number of CORESET groups configured in a frequency domain bandwidth, the greater the maximum number of TCI states allowed to be activated in the frequency domain bandwidth. When cross-CC scheduling is performed, the greater the number of CORESET groups configured in the frequency domain bandwidth where the PDCCH is located, the greater the maximum number of TCI states allowed to be activated in the frequency domain bandwidth where the PDSCH is located.

[0202] For example, the maximum number of TCI states allowed to be activated in a frequency domain bandwidth is proportional to the number of CORESET groups configured in the frequency domain bandwidth, or is proportional to the number of CORESET groups configured in the frequency domain bandwidth where the PDCCH that schedules the PDSCH in the frequency domain bandwidth is located.

[0203] In an exemplary embodiment, the larger the maximum number of TCI states corresponding to a code point in the TCI indication field of the DCI of a frequency domain bandwidth, the larger the maximum number of TCI states allowed to be activated in the frequency domain bandwidth, wherein the DCI schedules the PDSCH in the frequency domain bandwidth. For example, in the TCI state mapping table corresponding to the TCI indication field in the DCI, as shown in Table 8, the maximum number of TCI states corresponding to a code point is 1, then the maximum number of TCI states allowed to be activated in the frequency domain bandwidth is the number of valid code points, as shown in Table 9, the maximum number of TCI states corresponding to a code point is 2, then the maximum number of TCI states allowed to be activated in the frequency domain bandwidth is the number of valid code points multiplied by 2. The number of valid code points represents the number of code points to which the activated TCI state can correspond. Table 8 is a correspondence table between the code points provided in the present application and the TCI state activated by MAC-CE, and Table 9 is a correspondence table between the code points provided in the present application and the TCI state activated by MAC-CE. In Tables 8 and 9, although the number of bits in the TCI indication field in the DCI is 3, the number of valid code points is 4.

[0206] Table 9

[0207]

[0208]

[0209] In an exemplary embodiment, there is a correlation between the maximum number of TCI states corresponding to a code point in the TCI indication field of a frequency domain bandwidth DCI and the number of CORESET groups of the frequency domain bandwidth. Specifically, when the maximum number of TCI states corresponding to a code point in the TCI indication field of a frequency domain bandwidth DCI is greater than a first predetermined value, the number of CORESET groups of the frequency domain bandwidth is less than a second predetermined value, or when the number of CORESET groups of the frequency domain bandwidth is greater than or equal to the second predetermined value, the maximum number of TCI states corresponding to a code point in the TCI indication field of a frequency domain bandwidth DCI is less than or equal to the first predetermined value. For example, the first predetermined value is 1 and the second predetermined value is 2.

[0210] In an exemplary implementation, there are three ways to configure the TCI state list by RRC signaling:

[0211] Method 1: RRC signaling configures one or more TCI state lists for each BWP;

[0212] Method 2: RRC signaling configures one or more TCI state lists for each CC, and all BWPs in a CC share the one or more TCI state lists;

[0213] Mode 3: RRC signaling configures one or more TCI state lists for a CC group, and all BWPs of all CCs in the CC group share the one or more TCI state lists;

[0214] The multiple TCI state lists corresponding to the above-mentioned one frequency domain bandwidth correspond to different CORESET groups.

[0215] The specific RRC configuration method to be adopted can be notified by RRC signaling, or the configuration method of the above TCI state list can be determined based on whether the update or activation of the TCI state mapping table is shared.

[0216] In an exemplary embodiment, a TCI state list for PDCCH is configured for a CORESET set, instead of configuring a TCI state list for PDCCH for each CORESET set, wherein the TCI state list for PDCCH includes one or more TCI states. Further, through multiple MAC-CE commands, each CORESET in the CORSESET group selects one or more TCIstates in the TCI state list for PDCCH as the activated TCI state of the CORESET, or the CORESET set shares MAC-CE signaling, and the MAC-CE signaling selects one or more TCIstates in the TCI state list for PDCCH for the CORESET set as the activated TCI state of the CORESET.

[0217] The CORESET set is obtained by one of the following methods:

[0218] By receiving a control signaling sent by a base station, the control signaling includes the division of the CORESET set;

[0219] A CORESET in a frequency domain bandwidth is divided into the plurality of CORESET sets;

[0220] The CORESETs in the plurality of frequency domain bandwidths are divided into the plurality of CORESET sets;

[0221] The CORESTs in the same CORESET set correspond to the same set identifier.

[0222] The CORESET in the CORESET set includes CORESETs in one frequency domain bandwidth or multiple frequency domain bandwidths.

[0223] In an exemplary embodiment, multiple uplink frequency domain bandwidths share one SRS set, that is, the spatial transmit filters of the target channels and / or signals in the multiple uplink frequency domain bandwidths are obtained according to the SRSresource in the one SRS set.

[0224] Furthermore, the SRS set may be a code book SRS set or a non codebook SRS set.

[0225] In an exemplary embodiment, more than one TCIstate is activated for a CORESET at the same time, wherein the more than one TCIstate satisfies at least one of the following characteristics:

[0226] Different TCI states among the more than one TCI states correspond to different frequency domain resources of the CORESET;

[0227] Different TCI states among the more than one TCI states correspond to different time domain resources of the CORESET;

[0228] Different TCI states among the more than one TCI states correspond to different demodulation reference signal ports of the CORESET.

[0299] The predetermined parameter of the downlink information element and the predetermined parameter of the uplink target information element have the smallest subcarrier spacing.

[0300] In an exemplary embodiment, the spatial transmit filter of the uplink target channel and / or signal is obtained based on the receive filter of the downlink channel and / or signal, and / or the spatial transmit filter of the uplink target channel and / or signal is obtained based on the associated predetermined quasi-co-site reference signal of the downlink channel and / or signal.

[0301] Specifically, for example, the spatial filter of the uplink target channel and / or signal is obtained based on the receiving filter of the CORESET with predetermined characteristics in the slot closest to the uplink channel and / or signal, for example, based on the quasi-co-site reference signal of the associated spatial receiving parameters of the CORESET with the predetermined characteristics.

[0302] Fig.10 This is a schematic diagram provided by the present application considering that uplink slot n has a TA advance relative to downlink slot n. Fig.10As shown, when the spatial transmit filter of the uplink target channel or signal is obtained according to the most recent CORESET, it is necessary to consider that the uplink slot n has a TA advance relative to the downlink slot n. On the terminal side, the start of the downlink slot n is not aligned with the start of the uplink slot n. Under the same slot index, the start of the uplink slot n has a TA advance compared to the start of the downlink slot n.

[0303] Fig.11 This is a schematic diagram provided by the present application considering that uplink frame i has a TA advance relative to downlink frame i; Fig.11 As shown, when the spatial transmission filter of the uplink target channel or signal is obtained according to the most recent CORESET, it is necessary to consider that the uplink frame i has a TA advance relative to the downlink frame i; the uplink frame i has a TA advance relative to the downlink frame i (when TA is a negative value, the uplink frame i is TA backward relative to the downlink frame i). Especially when TA is relatively large, the downlink slot closest to the uplink slot n before the uplink target channel and / or signal is sent may not be slot n.

[0304] For this purpose, it can be further agreed that the CORESET with the predetermined characteristics in the second time unit closest to the uplink target channel and / or signal after considering the TA. Or the CORESET with the predetermined characteristics is the CORESET with the predetermined characteristics in the second time unit closest to the uplink target channel and / or signal before the predetermined time.

[0305] The CORESET of the predetermined feature is acquired based on at least one of the following information: the time domain symbol where the uplink target channel and / or signal is located, the time unit index of the uplink target channel and / or signal, the parameter set of the uplink target channel and / or signal, and the parameter set of the uplink target channel and / or signal. For example, the predetermined moment is the moment at which the uplink target channel and / or signal is located - the moment of TA. Furthermore, since the parameter sets of the uplink target channel and / or signal and the CORESET of the predetermined feature may be different and need to be aligned, the predetermined moment needs to be obtained according to the numerology of the two, wherein the unit of the predetermined time is a first time unit, and the first time unit may be one of the following: frame, subframe, slot, time domain symbol. For example, the unit of the first time unit is slot, then the CORESET of the predetermined feature is the CORESET with the predetermined feature in the time unit closest to the uplink target channel and / or signal before the predetermined slot. For example, the unit of the first time unit is time domain symbol, then the CORESET of the predetermined feature is the CORESET with the predetermined feature in the time unit closest to the uplink target channel and / or signal before the predetermined time domain symbol. For example, the first time unit is slot, and the predetermined moment is the CORESET with the predetermined feature in the time unit closest to the uplink target channel and / or signal before the predetermined time domain symbol. The downlink slot of Or the time is indexed as: In the downlink slot of , the time domain symbol index is the downlink time domain symbol of .

[0306] Among them, n PUCCH is the slot index where the uplink target channel and / or signal is located (the uplink slot index of TA is not considered, that is, the uplink slot index when the uplink frame and downlink frame boundaries are the same), the unit of TA is seconds, and the subcarrier spacing of PUCCH is The subcarrier spacing of PDCCH is It is the number of slots in a subframe based on the PDCCH subcarrier spacing. It is the number of slots included in a subframe, obtained based on the PUCCH subcarrier spacing. It is the number of OFDM included in a slot of PDCCH. It is the number of OFDM included in one slot of PUCCH.

[0307] Further, the second time unit may be one of the following: slot, sub-slot, subframe, frame, one or more time domain symbols, one or more slots, and the second time unit information may be configured by signaling. Further, the second time unit is one of the following based on the following subcarrier spacing: the subcarrier spacing of the uplink target channel and / or signal, the subcarrier spacing of the CORESET; the minimum subcarrier spacing between the subcarrier spacing of the uplink target channel and / or signal and the subcarrier spacing of the CORESET; the maximum subcarrier spacing between the subcarrier spacing of the uplink target channel and / or signal and the subcarrier spacing of the CORESET;

[0308] The CORESET of the predetermined characteristics is a CORESET in the second time unit that satisfies at least one of the following characteristics:

[0309] There is a corresponding relationship between the serving cell where the CORESET is located and the serving cell where the uplink target channel and / or signal is located, such as the same serving cell index. Of course, other corresponding relationships are not excluded. Or the serving cell where the CORESET is located is in the first predetermined CC group;

[0310] The CORESETID of the CORESET is the lowest, but can also be the highest;

[0311] The monitoring occasion of the CORESET in the second time unit occupies the most time domain symbols, and a monitoring occasion of a CORESET represents a monitoringoccasion of the CORESET search space;

[0312] The period of the monitoring occasion of the CORESET in the second time unit is the shortest, wherein a monitoring occasion of a CORESET represents a monitoringoccasion of the search space associated with the CORESET;

[0313] The CORESET associates at least one search space to be detected in the second time unit;

[0314] The CORESET belongs to a CORESET group. Furthermore, there is a corresponding relationship between the CORESET group and the target channel and / or signal.

[0315] Fig.12This is a schematic diagram of the need to determine the subcarrier spacing of the second time unit when one downlink slot corresponds to two uplink slots provided by the present application, such as Fig.12 As shown, the CORESET of the predetermined characteristic is the CORESET with the lowest CORESETID in the second time unit. If the second time unit is based on the subcarrier spacing of the CORESET to obtain the slot division boundary, the uplink target channel and / or signal transmission beams in the uplink slot2n and the uplink slot2n+1 are obtained according to the receiving beam of the CORESET0 in the downlink slotn-1. If the second time unit is based on the subcarrier spacing of the uplink target channel to obtain the slot division boundary, the uplink target channel and / or signal transmission beam in the uplink slot2n is obtained according to the receiving beam of the lowest CORESET in the first half of the downlink slotn-1, that is, CORESET0, and the uplink target channel and / or signal transmission beam in the uplink slot2n+1 is obtained according to the receiving beam of the lowest CORESET in the second half of the downlink slotn-1, that is, CORESET1.

[0316] Fig.13 It is a schematic diagram of the need to determine the subcarrier spacing of the second time unit when two downlink slots correspond to one uplink slot provided by the present application; Fig.13 As described, 2 downlink slots correspond to 1 uplink slot. If the second time unit is based on the subcarrier spacing of CORESET, the transmission beam of the uplink target channel and / or signal in slotn is obtained according to the receiving beam of the lowest CORESET in the downlink {slot2n-2 and slot2n-1}, that is, the transmission beam of the uplink target channel and / or signal in slotn is obtained according to the receiving beam of CORESET0. If the second time unit is based on the subcarrier spacing of the uplink target channel and / or signal, the transmission beam of the uplink target channel and / or signal in the first half of slotn is obtained according to the receiving beam of the lowest CORESET (i.e., CORESET0) in the downlink {slot2n-2. The transmission beam of the uplink target channel and / or signal in the second half of slotn is obtained according to the receiving beam of the lowest CORESET (i.e., CORESET1) in the downlink {slot2n-1.

[0317] Furthermore, if the number of repetitions of PUCCH is greater than 1, that is, aggregation is greater than 1, the transmission beam of PUCCH is determined as follows:

[0318] Method 1: For each repeated transmission among multiple repeated transmissions, the transmit beam of the target channel and / or signal of the repeated transmission is obtained according to the receive beam of the CORESET that meets the predetermined characteristics in the second time unit closest to the uplink target channel and / or signal of the repeated transmission before the predetermined time of the start time domain symbol of the repeated transmission. The CORESETs based on different repeated transmissions among multiple repeated transmissions may be different;

[0319] Method 2: The transmission beams of each repeated transmission in multiple repeated transmissions are the same, and the transmission beams of the uplink target channels and / or signals in all repeated transmissions are obtained according to the receiving beam of the CORESET that meets the predetermined characteristics in the second time unit closest to the start time domain symbol of the PUCCH before the predetermined time of the start time domain symbol of the PUCCH;

[0320] Method 3: Multiple repeated transmissions are divided into multiple repeated transmission groups, and the transmission beam in each group remains unchanged. Method 2 is adopted, and the transmission beams in different groups can be changed. That is, method 3 is a combination of method 1 and method 2.

[0321] The above is the transmission beam of the uplink target channel and / or signal based on the receiving beam of CORESET. This embodiment does not exclude that if there is PDSCH in the second time unit, the transmission beam of the uplink target channel and / or signal can also be obtained based on the receiving beam of PDSCH.

[0322] Further, the transmission beam of the uplink target channel and / or signal is obtained according to the time domain parameters of the uplink target channel and / or signal. For example, the uplink target channel and / or signal is a periodic channel and / or signal, or a semi-continuous channel and / or signal. These uplink target channels and / or signals have the following methods:

[0323] Method 1: Obtain the transmitting beam of the uplink target channel and / or signal in this cycle based on the receiving beam of the CORESET with predetermined characteristics in the second time unit closest to the uplink target channel and / or signal before the predetermined time of the starting time domain symbol of the uplink target channel and / or signal in each cycle. The CORESETs based on which the transmitting beams of the uplink target channel and / or signal in each cycle are based may be different, and even the CORESETs based on which different repeated transmissions in one cycle are based are different.

[0324] Method 2: Obtaining the transmit beams of the uplink target channels and / or signals in all cycles according to the receive beam of the CORESET with predetermined characteristics in the second time unit closest to the uplink target channel and / or signal before the predetermined time of the start time domain symbol of the uplink target channel and / or signal in the first cycle;

[0325] Method three: Divide multiple cycles into groups. The CORESET based on each cycle in each cycle group is the same, so the transmitted beams are also the same. The CORESET based on the cycles in different cycle groups can be different, so the transmitted beams can be different.

[0326] Method 4: For periodic or semi-continuous uplink target channels and / or signals, the correspondence between the periodic or semi-continuous uplink target channels and / or signals and a CORESET is directly established through signaling information. If the quasi-co-site reference signal of the CORESET changes, the transmission beam of the periodic or semi-continuous uplink target channel and / or signal also changes accordingly.

[0327] Furthermore, obtaining the transmission beam of the uplink target channel and / or signal according to the first predetermined CC group includes: the CORESET with the predetermined characteristic is a CORESET in the first predetermined CC group that satisfies the predetermined characteristic in the second time unit closest to the uplink target channel and / or signal before the predetermined moment of the uplink target channel and / or signal; when there are multiple CORESETs that satisfy the predetermined characteristic, the CORESET that satisfies the predetermined characteristic in the CC with the lowest and / or highest CC index in the first predetermined CC group is taken.

[0328] The above-mentioned obtaining of the transmit beam of the uplink target channel and / or signal according to the receive beam of CORESET or PDSCH may also include obtaining the transmit beam of the uplink target channel and / or signal according to the quasi-co-site reference signal of the associated spatial receive parameter of CORESET or PDSCH, or including obtaining the transmit beam of the uplink target channel and / or signal according to the DMRS of CORESET or PDSCH.

[0329] The above-mentioned "before the scheduled time of the uplink target channel and / or signal", wherein the uplink target channel and / or signal is the uplink target channel and / or signal without considering TA, after considering TA, the above-mentioned "before the scheduled time of the uplink target channel and / or signal" can also be replaced by "before the time when the uplink target channel and / or signal is sent".

[0330] In an exemplary embodiment, a method for acquiring a spatial filter of a PUCCH resource is configured in a PUCCH resource, or a method for acquiring a spatial filter of a PUCCH resource is configured in a PUCCH resource set, and all PUCCH resources in a PUCCH resource set share the same acquisition method, wherein the method for acquiring a spatial transmit filter of a PUCCH resource includes at least two of the following methods:

[0331] Method 1: explicitly configuring the spatial transmit filter of the PUCCH resource according to signaling, such as explicitly configuring the spatial relationship information of the PUCCH resource according to signaling, wherein the spatial relationship information includes a downlink reference signal or an uplink reference signal, and the spatial transmit filter of the PUCCH is obtained according to the spatial transmit filter of the uplink reference signal in the spatial relationship information, or the spatial transmit filter of the PUCCH is obtained according to the spatial receive filter of the downlink reference signal in the spatial relationship information;

[0332] Method 2: Determined based on the transmit beam of the nearest PRACH;

[0333] Method 3: Acquiring the receiving beam of the CORESET that meets the predetermined characteristics in the second time unit;

[0334] Mode 4: According to the reception performance of multiple downlink reference signals, the terminal selects one of the downlink reference signals by itself, and determines the transmission beam of the PUCCH according to the reception beam of the selected downlink reference signal;

[0335] In an exemplary embodiment, the correspondence between the uplink target channel and / or signal and the CORESET is directly established through signaling information. When the transmit beam of the CORESET changes, for example, when the TCI state of the CORESET is activated by MAC-CE signaling, the transmit beam of the uplink target channel and / or signal that has a corresponding relationship with the CORESET also changes accordingly.

[0336] In an exemplary embodiment, if the transmit beam of a non-periodic PUCCH is acquired according to the receive beam of a PDCCH that schedules the PUCCH, when the PUCCH includes HARQ-ACK information corresponding to multiple PDSCHs, the PUCCH resource where the HARQ-ACK information is located is obtained according to the last DCI (i.e., the DCI with the largest DCI index) among the multiple DCIs corresponding to the multiple PDSCHs, wherein the numbering of the multiple DCIs is first incremented by the serving cell index in a monitoring occasion of a PDCCH, and then incremented by the monitoring occasion index, wherein one PDCCH monitoring occasion includes a PDCCH monitoring occasion with the same starting position in multiple CCs, and the monitoring occasion index of the PDCCH is numbered incrementally according to the starting position of the PDCCH monitoring occasion.

[0337] Fig.14This is a schematic diagram of obtaining the PUCCH resource where the HARQ-ACK is located according to the information indicated in the last PDCCH provided by the present application, such as Fig.14 As shown, the HARQ-ACK of the PDSCH scheduled by PDCCH1 to PDCCH8 is fed back in PUCCH1 in slot (n+3) (i.e., slot n+3 in the figure), and the resource information of PUCCH1 on slot (n+3) is determined according to the PUCCH resource index indicated in PDCCH8. However, if the serving cell index of the Pcell is specified to be 0, the transmit beam of the PUCCH in the Pcell needs to be determined according to the transmit beam of the CORESET in other serving cells. In particular, when the transmit beam in the CORESET in the Pcell is more robust than the transmit beam in other serving cells, the robustness of the transmit beam of the PUCCH is not very good. For this reason, it can be specified that the resource information of the PUCCH is obtained according to PDCCH8, but the transmit beam of the PUCCH is obtained according to the receive beam of the last PDCCH in the second predetermined CC group, wherein the number of the PDCCH is first incremented in the same PDCCH monitoring occasion in the second predetermined CC group (if the number of CCs included in the second predetermined CC group is greater than 1), and then in the PDCCH monitoring occasion. For example, if the second predetermined CC group includes {Pcell, Scell2}, the transmit beam of PUCCH1 is obtained according to PDCCH7, or the second predetermined CC group includes {Pcell}. Then the PUCCH beam can be obtained according to PDCCH7, or the transmit beam of PUCCH1 is obtained according to the last DCI, but the DCI numbering is first a PDCCH monitoring occasion in which the serving cell index decreases, and then the monitoring occasion index increases.

[0338] The receiving beam acquisition according to the PDCCH includes acquiring the receiving beam according to the CORESET where the PDCCH is located.

[0339] In an exemplary embodiment, an uplink target channel and / or signal is associated with multiple CORESETs, and the terminal determines a quasi-co-location reference signal set based on the quasi-co-location reference signal of the spatial reception parameter associated with each CORESET in the multiple CORESETs, and the terminal determines a quasi-co-location reference signal set based on the one quasi-co-location reference signal.

[0340] In an exemplary embodiment, when a report setting is obtained based on a channel measurement NZP-CSI-RS resource set and multiple interference measurement resources NZP-CSI-RS resource sets, the predetermined parameters of the NZP-CSI-RS resource included in the multiple NZP-CSI-RS resource sets are the same, for example, the predetermined parameters include one or more of the following parameters: PRB starting position, number of PRBs, CDM-type (code division multiplexing type).

[0341] In an exemplary embodiment, a spatial transmit filter of an uplink target channel and / or signal is obtained according to multiple TCI states of a CORESET. For example, the multiple TCI states of the CORESET respectively correspond to different time domain resources, frequency domain resources, and ports of the uplink target channel and / or signal.

[0342] Or obtain the spatial transmission filter of the uplink target channel and / or signal according to multiple TCI states corresponding to multiple CORESETs, where one CORESET corresponds to one TCI state. The multiple TCI states correspond to different resources of the uplink channel and / or signal, respectively, and the resources include: time domain resources, frequency domain resources, port resources, and repetition times.

[0343] Different resources of the uplink target channel and / or signal obtain the spatial transmission filter of the uplink target channel and / or signal according to the quasi-co-location reference signal of the associated spatial reception parameter in the TCI state corresponding to the resource. For example, the spatial transmission filter of the uplink target channel and / or signal is obtained according to the spatial reception filter of receiving the quasi-co-location reference signal.

[0344] Further, the TCI state of the CORESET is a TCI state activated in the CORESET.

[0345] In an exemplary embodiment, the correspondence between the uplink target information element and the downlink information element is established directly through signaling information and / or predetermined rules. After the TCI of the downlink information element is updated, the spatial transmit filter of the uplink target information element is changed accordingly, and the uplink target information element always follows this downlink information element to determine the spatial transmit filter of the target information element. Unless the correspondence is updated. For example, the correspondence is established through RRC signaling, or it is determined that the resource index of the uplink target information element and the resource index of the downlink information element meet a predetermined condition, and then it is determined that the two have the correspondence.

[0346] The information elements include channels and / or signals.

[0347] Many non-periodic measurement reference signal resources can be dynamically triggered in one DCI. Now, the slotoffset of the non-periodic measurement reference signal is configured based on high-level signaling, where slotoffset is the slot interval between the PDCCH that schedules the non-periodic measurement signal and the slot where the non-periodic measurement reference signal is located. For example, the slot where the PDCCH is located is slotn, and the slot where the non-periodic measurement reference signal is located is n+slotoffset. This is when the subcarrier intervals occupied by the PDCCH and the non-periodic measurement reference signal are the same. When the subcarrier intervals are different, the slot where the non-periodic measurement reference signal is located may be obtained based on the subcarrier interval conversion.

[0348] However, this brings great restrictions to system scheduling, and the non-periodic measurement reference signal cannot be flexibly and dynamically scheduled on demand. For this purpose, the following solution is adopted.

[0349] In an exemplary embodiment, Fig.15 This is a flowchart of an information transmission method provided by the present application, which can be applied to the case of determining a quasi-co-location reference signal corresponding to a target channel and / or signal. The method can be performed by an information determination device provided by the present application, which can be implemented by software and / or hardware and integrated in a user device or a base station.

[0350] like Fig.15 As shown, the information transmission method provided in the present application mainly includes step S150.

[0355] The transmission direction of the aperiodic measurement reference signal resource, wherein the transmission direction includes uplink transmission and downlink transmission, such as the minimum time interval corresponding to the aperiodic downlink reference signal (such as the minimum time interval is 0 time domain symbols) is less than the minimum time interval corresponding to the aperiodic uplink reference signal (such as the minimum time interval is the minimum time interval between the PDCCH that schedules the aperiodic uplink measurement reference resource and the aperiodic uplink measurement reference resource, that is, the minimum time interval includes the minimum processing time for the terminal to receive the PDCCH and prepare to send the uplink aperiodic measurement reference signal)

[0356] The relationship between the carrier where the PDCCH is located and the carrier where the non-periodic measurement reference signal resource is located, such as the minimum time interval between the two when they are on different carriers is greater than the minimum time interval between the two when they are on the same carrier;

[0357] The relationship between the predetermined parameter information of the PDCCH and the predetermined parameter information of the non-periodic measurement reference signal resource; for example, the minimum time interval when the subcarrier spacings of the two are different is greater than the minimum time interval when the subcarrier spacings of the two are the same.

[0358] The predetermined parameter information of the PDCCH; for example, the predetermined parameter includes a subcarrier spacing.

[0359] The predetermined parameter information of the non-periodic measurement reference signal resource. For example, the predetermined parameter includes a subcarrier spacing.

[0360] In an exemplary embodiment, the minimum time interval is determined in at least one of the following ways:

[0361] When the aperiodic measurement reference signal resource is an uplink aperiodic measurement reference signal resource, determining the minimum time interval according to capability information reported by a communication node, wherein the communication node includes a communication node that sends the uplink aperiodic measurement reference signal resource;

[0362] When the PDCCH and the non-periodic measurement reference signal resource are on the same carrier, the first time interval is the minimum time interval;

[0363] When the PDCCH and the non-periodic measurement reference signal resource are on different carriers, the second time interval is the minimum time interval;

[0364] When the predetermined parameters of the PDCCH and the non-periodic measurement reference signal resource are the same, the third time interval is the minimum time interval;

[0365] When the predetermined parameters of the PDCCH and the non-periodic measurement reference signal resource are different, the fourth time interval is the minimum time interval;

[0366] The predetermined parameters include subcarrier spacing;

[0367] The first time interval is smaller than the second time interval; and / or the third time interval is smaller than the fourth time interval.

[0368] In an exemplary implementation, determining the time unit where the non-periodic measurement reference signal resource is located according to the third information includes:

[0369] When a predetermined condition is met, determining the time unit where the non-periodic measurement reference signal resource is located according to the third information;

[0370] The predetermined condition includes one of the following:

[0371] No time unit interval is configured in the first measurement reference signal resource set;

[0372] There is no time unit interval configured in the first measurement reference signal resource set, and a quasi-co-site reference signal with at least one associated spatial reception parameter is configured or activated in the frequency domain bandwidth where the non-periodic measurement reference signal resource is located; for example, in the TCI state list configured by RRC in the BWP where the non-periodic measurement reference signal resource is located, or in the TCI state set activated by MAC-CE in the BWP where the non-periodic measurement reference signal resource is located, there is at least one TCI state, in which a quasi-co-site reference signal with associated spatial reception parameters is configured or activated, that is, a quasi-co-site reference signal associated with QCL-Type D is configured or activated.

[0373] The carrier where the time unit interval is not configured in the first measurement reference signal resource set and the non-periodic measurement reference signal resource is located belongs to FR2; wherein FR2 includes a carrier whose center position is greater than a predetermined threshold;

[0374] The time unit determined according to the time unit interval configured in the first measurement reference signal resource set is not a valid time unit; for example

[0375] The time unit interval in the first measurement reference signal resource set is a predetermined value, such as a configured interval is a predetermined value, or a time interval is obtained according to a predetermined rule as a predetermined value, wherein the predetermined value is 0, or other values

[0376] In an exemplary implementation, determining the time unit where the non-periodic measurement reference signal resource is located according to the third information includes at least one of the following:

[0377] After the minimum time interval after the PDCCH, the first valid time unit is the time unit where the non-periodic measurement reference signal resource is located;

[0378] After the first predetermined time interval after the PDCCH, the first valid time unit is the time unit where the non-periodic measurement reference signal resource is located; wherein the first valid time unit is obtained according to the third information;

[0379] If any one of the first measurement reference signal resource set and the second measurement reference signal resource set cannot find a valid time unit within the predetermined time window after the PDCCH, the measurement reference resource is not received; for example, if any one of the channel measurement resource set and the interference measurement resource set associated with the same CSI repoting setting cannot find a valid time unit, it means that neither the first measurement reference signal resource set nor the second measurement reference signal set finds a valid time unit, that is, the reception of the first measurement reference signal resource set and the second measurement reference signal set is abandoned, especially the first measurement reference signal resource set and the second measurement reference signal set are both non-periodic measurement reference signal sets. The interference measurement resource set is an NZP CSI-RS set.

[0380] Furthermore, the effective time unit satisfies at least one of the following conditions:

[0381] If the valid time unit is within the predetermined time window after the PDCCH, that is, if it is not found within the predetermined time window, the transmission of the non-periodic measurement reference signal resource is abandoned;

[0382] On each time domain symbol in the first time domain symbol set in the valid time unit, the transmission direction on the time domain symbol and the transmission direction of the non-periodic measurement reference signal resource do not conflict; wherein the transmission direction on the time domain symbol is determined according to the time slot structure information, for example, all non-periodic measurement reference signal resources in the first measurement reference set can be transmitted without conflict, and it is considered to be a valid time unit, or all measurement reference signal resources in the first measurement reference set can be transmitted without conflict, and it is considered to be a valid time unit.

[0383] On each time domain symbol in the first time domain symbol set in the effective time unit, each non-periodic measurement reference signal resource in the first measurement reference signal resource set on the time domain symbol of the effective time unit and the quasi-co-location reference signal about the spatial reception parameter of the second downlink channel and / or signal on the time domain symbol do not conflict, wherein the non-periodic measurement reference signal is a downlink non-periodic measurement signal, for example, all non-periodic measurement reference signal resources in the first measurement reference set and the receiving beam of the second downlink channel and / or signal do not conflict, which is considered to be a valid time unit, or all measurement reference signal resources in the first measurement reference set can be transmitted without conflict, which is considered to be a valid time unit, for example, the second downlink channel and / or signal includes at least one of the following: a downlink channel and / or signal with a scheduling delay greater than a predetermined value, a search space, a periodic downlink measurement reference signal, a semi-continuous downlink measurement reference signal, and the end position of the PDCCH for scheduling the second downlink channel and / or signal is earlier than the end position of the PDCCH for scheduling the non-periodic measurement reference resource;

[0384] On each time domain symbol in the first time domain symbol set in the effective time unit, each non-periodic measurement reference signal resource in the first measurement reference signal resource set on the time domain symbol and the spatial transmission filter communication node of the second uplink channel and / or signal on the time domain symbol can be transmitted simultaneously, wherein the communication node is a communication node that sends the non-periodic measurement reference signal, wherein the non-periodic measurement reference signal is an uplink non-periodic measurement signal; for example, the second uplink channel and / or signal includes at least one of the following: an uplink channel and / or signal with a scheduling delay greater than a predetermined value, an end position of the PDCCH that schedules the second uplink channel and / or signal is earlier than an end position of the PDCCH that schedules the non-periodic measurement reference resource, a search space, a periodic uplink measurement reference signal, a semi-persistent uplink measurement reference signal, PUSCH with a configured grant, i.e., a PUSCH that is free of scheduling, a periodic PUCCH, and a semi-persistent PUCCH;

[0385] Within the PDCCH and the first valid time unit, the time structure information does not change;

[0386] Within the predetermined time window after the PDCCH, the time structure information does not change;

[0387] Between the PDCCH and the first valid time, according to the same time slot structure information;

[0388] within the predetermined time window after the PDCCH, according to the same time slot structure information;

[0389] For example, between the PDCCH and the first valid time unit, the time structure information cannot be changed, otherwise when determining the above-mentioned conflict problem, it will cause troublesome behavior of the terminal;

[0390] The time interval between the PDCCH including the time slot structure information most recently before the effective time unit and the start symbol of the sounding reference signal resource in the effective time is greater than or equal to the first predetermined time interval.

[0391] Further, the first time domain symbol set includes one of the following time domain symbol sets in a time unit:

[0392] The time domain symbol occupied by the non-periodic measurement reference signal resource;

[0393] time domain symbols occupied by all the measurement reference signal resources in the first measurement reference signal resource set;

[0394] Time domain symbols occupied by all the measurement reference signal resources in the first measurement reference signal resource set and the second measurement reference signal resource set.

[0395] In an exemplary embodiment, it is characterized in that the time slot structure information is obtained according to at least one of the following information:

[0396] According to the time domain symbol position where the synchronization signal is located;

[0397] According to the semi-static frame structure;

[0398] According to DCI format 2_0;

[0399] According to the time domain symbol where the PRACH is located;

[0400] The time slot structure information before the PDCCH, the most recent valid time slot structure information before the PDCCH, for example, to determine whether a time unit is valid, it is necessary to obtain the transmission direction of each time domain symbol in the time unit according to the time slot structure information, but the notification signaling time slot structure information can be the above information, and the terminal needs to determine that even if there is an update of the time slot structure information later, when judging the valid time unit, the most recent valid time slot structure information before the PDCCH is used.

[0401] The time slot structure information in each time unit after the PDCCH includes the valid time slot structure information in each time unit, that is, there is a time slot structure information update signaling after the PDCCH, then in each time unit, the transmission direction of each time domain symbol in the time unit is determined according to the most recent time slot information in the time unit;

[0402] Because the above information can determine the transmission direction of a time domain symbol, and the validity level of these time slot structure information is higher than the transmission direction determined by the aperiodic measurement reference signal resource, for example, for the time domain symbol 13 in which the aperiodic uplink measurement reference signal resource occupies a slot, in the time domain of searching for the valid time unit, if the transmission direction of the time domain symbol 13 is determined to be uplink according to the aperiodic uplink measurement reference signal resource, but the transmission direction in the slot is determined to be downlink according to the above time slot structure information, then the slot is not a valid slot.

[0403] In an exemplary embodiment, it is characterized in that the time unit includes one of the following: Slot; Subframe; Sub-slot, wherein a sub-slot includes one or more consecutive time domain symbols in a slot, for example, when searching for a valid time unit, the search is performed in units of the time unit, and the number of time domain symbols included in the sub-slot is greater than or equal to the number of time domain symbols included in the maximum interval between the time domain symbols occupied by all measurement reference signal resources in the first measurement reference signal resource set.

[0404] In an exemplary embodiment, the first predetermined time interval includes:

[0405] The second predetermined parameter indicated by the control channel for scheduling the non-periodic measurement reference signal is applied to the transmission of the non-periodic reference signal, and the minimum time interval between the PDCCH and the non-periodic measurement reference signal is required; wherein the first predetermined parameter includes one of the following: spatial transmission filter information, quasi-co-site reference signal, quasi-co-site reference signal associated with spatial reception parameters. The predetermined parameters include the first predetermined parameters. For example, when the time interval between the PDCCH for scheduling the non-periodic CSI-RS and the non-periodic CSI-RS is less than the first predetermined time interval, the TCI indicated in the PDCCH cannot be used to obtain the TCI of the non-periodic CSI-RS, because the terminal has not decoded the PDCCH at this time, or cannot switch to the TCI indicated in the PDCCH. Only when the time interval between the PDCCH for scheduling the non-periodic CSI-RS and the non-periodic CSI-RS is greater than or equal to the time domain of the first predetermined time interval, the TCI of the non-periodic CSI-RS indicated in the PDCCH can be used to receive the non-periodic CSI-RS.

[0406] The second predetermined parameter indicated by the control channel for scheduling the non-periodic measurement reference signal is applied to the transmission of the non-periodic reference signal, and the time interval between the PDCCH including the time slot structure information most recently before the effective time unit and the starting symbol of the measurement reference signal resource in the effective time is greater than or equal to the first predetermined time interval. For example, after the PDCCH for scheduling the non-periodic CSI-RS and between the effective time unit, there is SFI information indicated in DCI format2_0. From receiving this DCI2_0 to knowing that this is a valid time unit and using the TCI in the PDCCH for scheduling the non-periodic CSI-RS to receive the non-periodic CSI-RS, the terminal needs processing time, and this processing time requires at least the first predetermined time interval. It can also be called the minimum time length required, that is, the time interval can also be called the time length.

[0407] In an exemplary embodiment, the predetermined parameter comprises a second predetermined parameter, wherein the second predetermined parameter comprises at least one of the following: a subcarrier spacing, such as a different subcarrier spacing, and the minimum time interval is different.

[0408] In an exemplary embodiment, the second measurement reference signal set satisfies at least one of the following characteristics:

[0409] The first measurement reference signal set and the second measurement reference signal resource set are associated with the same measurement reporting configuration;

[0410] One of the first measurement reference signal set and the second measurement reference signal resource set is a channel measurement reference signal resource set, and the other is an interference measurement reference signal resource set. For example, when any one of the channel measurement resource set and the interference measurement resource set associated with the same CSI repoting setting cannot find a valid time unit, it means that neither the first measurement reference signal resource set nor the second measurement reference signal set finds a valid time unit, that is, the reception of the first measurement reference signal resource set and the second measurement reference signal set is abandoned, especially the first measurement reference signal resource set and the second measurement reference signal set are both non-periodic measurement reference signal sets. The interference measurement resource set is an NZP CSI-RS set.

[0411] The first measurement reference signal set corresponds to antenna port group 1, and the second measurement reference signal resource set corresponds to antenna port group 2, wherein the difference set between antenna port group 1 and the antenna port group 2 is not empty, and / or the intersection set is empty, for example, the first measurement reference signal set and the second measurement reference signal set are two SRS sets for uplink antenna switching, that is, the resources in each SRS set in the two sets configured as antena swiching find a valid time unit in the predetermined time window, otherwise, the two SRS sets are abandoned, that is, no valid time unit is found, and the two SRS sets are not sent.

[0412] The second measurement reference signal resource set includes non-periodic measurement reference signal resources.
