Description

[0001] This application is a divisional application. The original application has the application number 201810912239.4, the application date is August 10, 2018, and the invention title is "A method and apparatus for determining a quasi-co-located reference signal set". Technical Field

[0002] The embodiments of the present invention relate to the field of communications, and more particularly to a signal receiving method, a transmitting method, an apparatus, a device, and a storage medium. Background Technology

[0003] Release-15 NR User Equipment (UE) supports beam-based high-frequency communication. The core issue of beam-based communication is how to accurately acquire the beam.

[0004] Release-15 NR UEs only support transmitting signals with one Transmission Receiver Point (TRP) at a time. When the beam isolation of multiple TRPs is relatively high, multiple TRPs can be used to transmit multi-stream signals with the same user simultaneously, improving spectral efficiency. On the other hand, multiple TRPs transmitting the same signal with the same user simultaneously can improve the robustness of beam communication, thus requiring NR-UEs to support transmitting signals with multiple TRPs at the same time. When two or more TRPs are operating at high frequencies, and the UE needs to receive signals transmitted by two or more TRPs simultaneously, especially when the terminal cannot obtain the beam through Downlink Control Information (DCI), the core problem this paper aims to solve is determining which beam the UE should use to transmit with multiple TRPs.

[0005] On the other hand, in high-frequency communication, when beams of different signals conflict at the same time, or when terminals cannot receive the beams of two signals at the same time, how should this be handled? Current discussions generally aim to keep the beams of two signals consistent when the base station schedules them at the same time. However, to increase the flexibility of the base station, it should be allowed for the beams of signals scheduled later to conflict with the beams of signals that have been scheduled earlier. This article will further describe how to resolve beam conflicts. Summary of the Invention

[0706] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be arbitrarily combined with each other.

[0707] The steps illustrated in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in a different order than that shown here.

[0708] NR supports dynamic indication of the beam used by the Physical Downlink Shared Channel (PDSCH) through Downlink Control Information (DCI). Specifically, the beam used by the PDSCH is indicated by the Transmission Configuration Indication (TCI) field in the DCI. That is, the TCI field indicates the quasi-co-location (QCL) reference signal set of the demodulation reference signal (DMRS) of the PDSCH. In other words, the reference signals in the DMRS and QCL reference signal set of the PDSCH satisfy a QCL relationship with respect to a class of QCL parameters. Thus, the terminal can obtain the QCL parameters of the DMRS of the PDSCH based on the QCL parameters of the reference signals in the QCL reference signal set.

[0709] The QCL parameters include at least one of the following parameters:

[0710] Doppler shift, Doppler spread, average delay, multipath spread, and spatial Rx parameter.

[0711] As shown in Table 1, TCI state 1 indicates that DMRS group 1 and Channel State Information Reference Signal 1 satisfy the QCL relationship with respect to {Doppler shift, Doppler spread, average delay, delay spread}, and DMRS group 1 and CSI-RS2 satisfy the QCL relationship with respect to {Spatial Rx parameter}. In this paper, the QCL reference signal set of DMRS group 1 is referred to as {CSI-RS1, CSI-RS2}.

[0712]

[0713] Table 1

[0714] Specifically, the terminal obtains the Spatial Rx parameter of the DMRS of the PDSCH based on the reference signal associated with the Spatial Rx parameter in the QCL reference signal set indicated by the TCI field. This allows the terminal to use a suitable receive beam to receive the PDSCH. However, the QCL reference signal set of the PDSCH can only be obtained through the TCI field indicated in the DCI when the transmission time interval between the DCI and the PDSCH is greater than or equal to a predetermined threshold K. When the transmission time interval between the DCI and the PDSCH is less than the predetermined threshold, the terminal has not yet decoded the DCI or has not had time to switch the beam to the receive beam indicated by the TCI field in the DCI when receiving the PDSCH. Therefore, the terminal cannot use the beam indicated in the DCI to receive the PDSCH. To address this issue, the NR now specifies that when the transmission time interval between the DCI and the PDSCH is less than the predetermined threshold K, the terminal uses the Control Channel Resource Set (CORESET) with the lowest Control Channel Resource Set ID (CORESETID) in the time unit closest to the PDSCH. The beam of the set is used to receive the PDSCH, wherein the time unit contains at least one CORESET that the terminal needs to detect, that is, the set of QCL reference signals that satisfy the QCL relationship with the DMRS of the PDSCH at this time is the set of QCL reference signals of the demodulation reference signal of the CORESET.

[0715] The above scheme is only applicable to single TRP transmission. When there are two or more TRPs communicating with the terminal, the above scheme is not applicable.

[0716] For example, such as Figure 1 As shown, TRP1 and TRP2 serve the UE. TRP1 sends (DCI1, PDSCH1) to the UE, and TRP2 sends (DCI2, PDSCH2) to the UE. Since there is no ideal backhaul between TRP1 and TRP2, they independently schedule PDSCH and exist at the same time or in the same time unit (e.g., in the same slot). The terminal needs to receive PDSCH1 from TRP1 and PDSCH2 from TRP2 simultaneously. That is, the time domain resources occupied by PDSCH1 and PDSCH2 at least partially overlap or occupy the same time unit; or PDSCH1 and PDSCH2 may be in different time units, but their receive beaming issues must be considered independently because the transmit beams of PDSCH1 and PDSCH2 are different. In other words, both TRP1 and TRP2 send DCI and data channels. DCI1 is used to schedule PDSCH1, and DCI2 is used to schedule PDSCH2. Figure 1 In the process, when the time interval between DCI1 and PDSCH1 is less than the predetermined threshold K, and the time interval between DCI2 and PDSCH2 is also less than the predetermined threshold K, the receiving beam problem of PDSCH1 and PDSCH2 needs to be considered.

[0717] In this paper, a QCL reference signal set for a reference signal means that the reference signal and the reference signals in the QCL reference signal set satisfy a QCL relationship with respect to at least one QCL parameter.

[0718] Where two reference signals satisfy a QCL relationship with respect to at least one QCL parameter, it means that the QCL parameter of one reference signal can be obtained from the QCL parameter of the other reference signal.

[0719] See Figure 2 One embodiment of the present invention proposes a method for determining a QCL reference signal set, comprising:

[0720] Step 200: Select N2 control channel resources from the control channel resources included in N1 time units; where N1 and N2 are integers greater than or equal to 1.

[0765] A CORESET (Control resource set), a search space set, a search space, a candidate control channel, and a Physical Downlink Control Channel (PDCCH).

[0766] One CORESET corresponds to one control channel resource, one PDCCH occupies part or all of the frequency domain resources in one CORESET, one CORESET corresponds to one set of frequency domain resources, one CORESET is a set of frequency domain resources for transmitting control channels, and the time domain resources corresponding to the CORESET are determined by the configuration information in the search space set associated with the CORESET.

[0767] One time unit includes control channel resources, indicating that the control channels included in this control channel resource need to be detected in this time unit.

[0768] For example, when the control channel resource is CORESET, whether a time unit includes the CORESET is determined based on whether the CORESET is associated with at least one search space set that needs to be detected in that time unit.

[0769] Specifically, when a CORESET is associated with at least one search space set that needs to be detected in that time unit, the time unit is determined to include the CORESET; when a CORESET is not associated with any search space set that needs to be detected in that time unit, the time unit is determined to exclude the CORESET.

[0770] For example, if a CORESET has a search space set configured in this time unit, but the number of candidate control channels configured in this time unit exceeds the terminal's detection capability, such as exceeding a predetermined threshold, then according to certain discarding principles, no search space set of this CORESET will be detected, and therefore this CORESET will not be included in this time unit.

[0771] In this embodiment of the invention, N2 control channel resources can be selected from the control channel resources included in N1 time units according to the channel or signal configuration information;

[0772] Alternatively, N2 control channel resources can be selected from the control channel resources included in N1 time units based on the configuration information of the control channel resources where the scheduling channel or signal control channel is located.

[0773] Alternatively, select N2 control channel resources that satisfy the second predetermined characteristic from the control channel resources included in the N1 time units;

[0774] Wherein, the channel or signal is the channel or signal corresponding to at least one of the M port groups.

[0775] The configuration information of the channel or signal, or the configuration information of the control channel resources for scheduling the channel or signal, indicates the N2 control channel resources selected from the control channel resources included in the N1 time units.

[0776] Among them, the N2 control channel resources that satisfy the second predetermined characteristic selected from the control channel resources included in the N1 time units include any one of the following:

[0777] Select N2 control channel resources with the Lth to (L+N2-1)th lowest control channel resource identifiers from the control channel resources included in the N1 time units;

[0778] From the control channel resources included in the N1 time units whose demodulation reference signals do not satisfy the quasi-co-location relationship with respect to spatial reception parameters, select N2 control channel resources with the Lth to (L+N2-1)th lowest control channel resource identifiers;

[0779] Where L is an integer greater than or equal to 1.

[0780] For example, such as Figure 1 As shown, there is no ideal backhaul between TRP1 and TRP2. TRP1 and TRP2 are independently scheduled, resulting in PDSCH1 and PDSCH2 being on slot(n). Among the slots preceding slot(n), including those containing the CORESETs the terminal needs to detect, the slot closest to slot(n) is slot(n-2). The CORESETs the terminal needs to detect on slot(n-2) include {CORESET0, CORESET1, CORESET2, CORESET3}. The terminal determines the CORESET based on the TCI configuration of CORESET0 (i.e., the demodulation reference signal of CORESET0 and the QCL reference signal included in the TCI configuration information of CORESET0, which satisfy a QCL relationship with respect to a class of QCL parameters). That is, the QCL reference signal set of the demodulation reference signal of CORESET0 is obtained according to the TCI configuration in CORESET0. The terminal obtains the QCL reference signal set of PDSCH1's DMRS according to the TCI configuration of CORESET1 (that is, the demodulation reference signal of CORESET1 and the QCL reference signal included in the TCI configuration information of CORESET1 satisfy a QCL relationship with respect to a class of QCL parameters). For example, the QCL reference signal set of PDSCH2's DMRS is the QCL reference signal set of CORESET1's demodulation reference signal. If there is only one CORESET in slot (n-2), the QCL reference signal set of PDSCH2 is obtained according to the beam with the lowest CORESETID in the slot before slot (n-2). That is, the slot that includes the CORESET and is closest to slotn is slot(n-2), and there is only one CORESET in slot(n-2). The following method can be used to determine the beams of PDSCH1 and PDSCH2:

[0781] Method 1 for selecting N2 control channel resources: From slots containing at least two CORESETs, select the time unit closest to the slots containing PDSCH1 and PDSCH2, and select the two CORESETs with the lowest CORESETIDs from the first to the second lowest CORESETIDs. Based on the QCL reference signal sets of the demodulation reference signals of these two CORESETs, obtain the QCL reference signal sets of the demodulation reference signals for PDSCH1 and PDSCH2 respectively. For example, slots (n) and (n-1) do not contain any CORESETs, slot (n-2) only contains CORESET0, and slot (n-3) contains {CORESET1, CORESET3}. Then, based on the QCL reference signal sets of the demodulation reference signals of {CORESET1, CORESET3} in slot (n-3), obtain the QCL reference signal sets of PDSCH1 and PDSCH2 respectively, as shown in Figure 3(a).

[0782] Method 2 for selecting N2 control channel resources: Select the two CORESETs from the time unit set that is closest to slot(n) from the time unit set that includes at least two CORESETs. Select the two CORESETs from the first lowest CORESETID to the second lowest CORESETID. Obtain the QCL reference signal sets of the demodulation reference signals of PDSCH1 and PDSCH2 respectively based on the QCL reference signal sets of the demodulation reference signals of these two CORESETs. For example, slot(n) includes {CORESET0}, slot(n-1) includes {CORESET0}, slot(n-2) does not include CORESET, and slot(n-3) includes {CORESET1, CORESET3}. Then, select the QCL reference signal sets of the demodulation reference signals of {CORESET0, CORESET1} from {CORESET0, CORESET1, CORESET3} included in {slot(n)~slot(n-3)} as the QCL reference signal sets of PDSCH1 and PDSCH2 respectively, as shown in Figure 3(b).

[0783] Method 3 for selecting N2 control channel resources: Select the time unit set closest to slot(n) from the time unit set of different CORESETs that include at least two demodulation reference signals. Select the two CORESETs from the first lowest CORESETID to the second lowest CORESETID. Based on the QCL reference signal sets of the demodulation reference signals of these two CORESETs, obtain the QCL reference signal sets of the demodulation reference signals of PDSCH1 and PDSCH2 respectively. For example, slot(n) includes {CORESET0}, slot(n-1) includes {CORESET0}, slot(n-2) does not include CORESET, and slot(n-3) includes {CORESET1, CORESET3}. Then, the {CORESET0} included in {slot(n)~slot(n-3)} are... The QCL reference signal sets of the demodulated reference signals {CORESET0, CORESET1} within {CORESET0, CORESET1} are selected as the QCL reference signal sets of PDSCH1 and PDSCH2, respectively, as shown in Figure 3(b). Although CORESET0 and CORESET1 are different CORESETs, their demodulated reference signals have the same QCL reference signal set, which is QCL reference signal set 1. The QCL reference signal set of the demodulated reference signal of CORESET3 is QCL reference signal set 2. Therefore, the QCL reference signal set of the demodulated reference signal of PDSCH1 is the QCL reference signal set 1 corresponding to CORESET0 and CORESET1, and the QCL reference signal set of the demodulated reference signal of PDSCH2 is the QCL reference signal set 2 corresponding to CORESET3.The demodulation reference signals of CORESET0 and CORESET1 have the same QCL reference signal set. In another embodiment of this example, the demodulation reference signals of CORESET0 and CORESET1 have different QCL reference signal sets, but their QCL reference signals with respect to spatial receiving filter parameters are the same. For example, the demodulation reference signal of CORESET0 has a QCL reference signal set {CSI-RS1, CSI-RS2}, where the QCL parameters associated with CSI-RS1 are {Doppler shift, Doppler spread, average delay, delay spread}, and the QCL parameter associated with CSI-RS2 is the Spatial Rx parameter. The demodulation reference signal of CORESET1 has a QCL reference signal set {CSI-RS3, CSI-RS2}, where the QCL parameters associated with CSI-RS3 are {Doppler shift, Doppler spread, average delay, delay spread}, and the QCL parameter associated with CSI-RS2 is the Spatial Rx parameter. Rxparameter. Therefore, the QCL reference signal set of PDSCH1 is obtained using the QCL reference signal set of CORESET0. That is, from the set of time units of CORESETs that include at least two demodulation reference signals that do not satisfy the QCL relationship with respect to the Spatial Rx parameter, the set of time units closest to slot(n) is selected, and the two CORESETs from the first lowest CORESETID to the second lowest CORESETID are selected.

[0784] In Figures 3(a) and 3(b), the time interval between DCI1 and PDSCH1 is less than a predetermined threshold K, and the time interval between DCI2 and PDSCH2 is also less than a predetermined threshold K, for example, K is 4 slots. Since DCI1 and DCI2 will be sent in two different CORESETs, starting from slot(n), before encountering DCI1 and DCI2, a CORESET that meets the requirements may be found, or it may not be found. If it cannot be found, it will encounter the CORESET where DCI1 and DCI2 are located. Thus, N1 time units belong to the time units between the time unit where DCI is located and the time unit where PDSCH is located, that is, the time interval between the N1 time units and the PDSCH is less than K.

[0785] Method four for selecting N2 control channel resources: From the time units of at least L1 control channel resources satisfying a first predetermined characteristic, N2 control channel resources satisfying a second predetermined characteristic are selected from the N1 time units closest to the channel or signal (from the 1st to the N1th). The control channel resources satisfying the first predetermined characteristic include at least one of the following: control channel resources whose center carrier of the component carrier is greater than a predetermined threshold; control channel resources where a demodulation reference signal and a quasi-co-address reference signal satisfy a quasi-co-address relationship with respect to spatial reception filtering parameters; control channel resources where the demodulation reference signal is configured with respect to a quasi-co-address reference signal with respect to spatial reception filtering parameters; and control channels falling within the same frequency domain bandwidth as the port group. Resources; wherein, a frequency domain bandwidth can be the bandwidth corresponding to a component carrier (CC) or the bandwidth corresponding to a bandwidth portion (BWP); the demodulation reference signals of different control channel resources in the N2 control channel resources or the L1 control channel resources do not satisfy the quasi-co-address relationship with respect to the spatial receiving filter parameters; control channel resources belonging to a predetermined frequency domain bandwidth or a predetermined frequency domain bandwidth group; control channel resources associated with at least one candidate control channel monitored by a first communication node in the time unit, wherein the first communication node is the receiving node of the port group; control channel resources belonging to a predetermined control channel resource group; control channel resources belonging to a frequency domain bandwidth or a frequency domain bandwidth group. The control channel resources with the second predetermined feature satisfy one of the following characteristics: Among the control channel resources with the first predetermined feature included in the N1 time units, there are control channel resources with the lowest identifier number from Lth to L+N2-1th; when there are more than one control channel resource with the same identifier among the control channel resources with the same identifier, the control channel resource belonging to the frequency domain bandwidth with the lowest frequency domain bandwidth identifier is selected from the multiple control channel resources with the same identifier; the control channel resources belonging to the F frequency domain bandwidths with the lowest frequency domain bandwidth identifier are included in the set of control channel resources with the first predetermined feature included in the N1 time units.

[0786] Alternatively, PDSCH1 and / or PDSCH2 are semi-persistent scheduled PDSCHs (SPS-PDSCH), and the DCI1 for scheduling PDSCH1 and the DCI2 for scheduling PDSCH2 are in slot (n-20). The period of PDSCH1 and PDSCH2 is 5 slots, meaning that PDSCH1 and PDSCH2 are transmitted once every 5 slots. The interval between PDSCH1 and PDSCH2 in slot (n) and the time between their DCIs exceeds 4 periods of semi-persistent scheduled PDSCHs. In Figures 3(a) and 3(b), PDSCH1 should be configured with the CORESET that should be selected as the first lowest CORESETID, and PDSCH2 should be configured with the CORESET that should be selected as the second lowest CORESETID. In the aforementioned distances, each PDSCH includes only one DMRS group. However, in this embodiment, it is not excluded that each PDSCH may correspond to multiple DMRS groups. Therefore, PDSCH1 is configured to select the 1st to 2nd lowest CORESETID CORESET, and PDSCH2 is configured to select the 3rd lowest CORESETID CORESET. That is, when the distance between the currently semi-persistently scheduled channel and the DCI of the scheduled semi-persistent PDSCH is sufficiently large, such as exceeding a predetermined number of semi-persistent periods, the quasi-co-address reference signal of the semi-persistent channel is obtained by following the set of quasi-co-address reference signals of the control channel resources satisfying the second predetermined characteristic in the time unit closest to the current semi-persistent PDSCH within the time unit containing the control channel resources satisfying the first predetermined characteristic. When the distance between the currently semi-persistently scheduled channel and the DCI of the scheduled semi-persistent PDSCH is relatively small, such as within the predetermined number of semi-persistent periods, the set of quasi-co-address reference signals of the currently semi-persistently scheduled channel can be obtained based on the TCI field indicated by the DCI of the scheduled semi-persistent PDSCH.

[0787] In embodiments of the present invention, at least one of the following characteristics is satisfied by the channel or signal corresponding to at least one of the M port groups:

[0788] The time interval between the channel or signal and the control signaling that schedules the channel or signal is less than a predetermined threshold;

[0789] The time interval between the channel or signal and the control channel that schedules the channel or signal is less than a predetermined threshold;

[0791] The signal is a periodic signal;

[0792] The signal is a half-cycle signal;

[0793] The channel is a semi-persistent scheduling channel.

[0794] The notification information can be a TCI field.

[0795] In another embodiment of the present invention, the N1 time units include M2 ​​time unit groups, wherein the M port groups correspond to the M2 time unit groups, and M2 is a positive integer greater than or equal to 1;

[0796] And / or, M port groups correspond to M3 control channel resource groups, where M3 is a positive integer greater than or equal to 1.

[0797] The intersection of time units included in different time unit groups is non-empty.

[0798] The quasi-co-address reference signal set of the port group corresponding to the time unit group is determined based on the N4 control channel resources selected from the time unit group. In other words, the quasi-co-address reference signal set of the port group corresponding to the time unit group is the QCL reference signal set of the DMRS for the N4 control channel resources.

[0799] Wherein, N4 is a positive integer less than or equal to N2, and the N4 values ​​corresponding to different time unit groups may be the same or different.

[0800] Each time unit group includes N3 time units that are closest to the channel or signal from the 1st to the N3rd time units that satisfy the first characteristic; where N3 is an integer greater than or equal to 1.

[0801] Wherein, the time unit satisfying the first feature includes at least L2 control channel resources in a control channel resource group, where L2 is an integer greater than or equal to 1;

[0810] Based on the N4 control channel resources, determine the quasi-co-address reference signal set for the port group corresponding to the control channel resource group;

[0811] Where N3 is a positive integer less than or equal to N1, N4 is a positive integer less than or equal to N2, L2 is a positive integer less than or equal to N4, and the N4 values ​​corresponding to different port groups may be the same or different, and the N3 values ​​corresponding to different port groups may be the same or different.

[0812] The selection of N4 control channel resources from the control channel resources belonging to the control channel resource group included in the N3 time units includes:

[0813] Select N2 control channel resources with the lowest control channel resource identifier from Lth to (L+N2-1)th from the control channel resource resources belonging to the control channel resource group included in the N1 time units;

[0814] From the control channel resources belonging to the control channel resource group included in the N1 time units, select the N2 control channel resources with the Lth to (L+N2-1)th lowest control channel resource identifiers from the control channel resources whose demodulation reference signal does not satisfy the quasi-co-address relationship with respect to spatial reception parameters;

[0815] Where L is an integer greater than or equal to 1.

[0816] Among them, the M port groups correspond to M3 control channel resource groups, including at least one of the following:

[0817] Each of the M port groups corresponds to at least one control channel resource group;

[0818] Each of the M3 control channel resource groups corresponds to at least one port group;

[0819] The correspondence between the M port groups and the M3 control channel resource group is determined based on the signaling information;

[0820] The correspondence between the M port groups and the M3 control channel resource group is determined according to the agreed rules;

[0821] Determine the control channel resource group corresponding to a port group based on the signaling information;

[0822] A control channel resource group corresponding to a port group is determined according to the agreed rules;

[0823] A port group corresponds to a control channel group, which is the control channel resource group to which the control channel information of the scheduling channel or signal belongs, wherein the channel or signal includes the port group.

[0824] A control channel group corresponding to a port group is a control channel resource group that includes control channel resources in a predetermined component carrier (CC).

[0825] A control channel resource group corresponding to a port group is a control channel resource group that includes control channel resources in a predetermined member carrier group.

[0826] A control channel resource group corresponding to a port group is a control channel resource group that includes control channel resources satisfying a first characteristic; wherein, the control channel resources satisfying the first characteristic are associated with a second QCL reference signal set, and different control channel resources satisfying the first characteristic are associated with different second QCL reference signal sets; the intersection between the second quasi-co-address reference signal set and the third quasi-co-address reference signal set of the demodulated reference signal of the control channel resources satisfying the first characteristic is non-empty, and / or the second quasi-co-address reference signal set and the third quasi-co-address reference signal set correspond to different control signaling bit fields; the reference signals in the third quasi-co-address reference signal set and the demodulated reference signals of the control channel resources satisfying the first characteristic satisfy a quasi-co-address relationship with respect to the first type of quasi-co-address parameters;

[0827] A control channel resource group corresponding to a port group is a control channel resource group that includes control channel resources satisfying the second characteristic; wherein, the seventh QCL reference signal set of the demodulation reference signals of the control channel resources satisfying the second characteristic is associated with the sixth QCL reference signal set, and the sixth QCL reference signal set associated with the seventh QCL reference signal set of different control channel resources satisfying the second characteristic is different; the intersection between the sixth quasi-co-address reference signal set and the seventh quasi-co-address reference signal set is non-empty, and / or the sixth quasi-co-address reference signal set and the seventh quasi-co-address reference signal set correspond to different control signaling bit fields; the reference signals in the seventh quasi-co-address reference signal set and the demodulation reference signals of the control channel resources satisfying the second characteristic satisfy a quasi-co-address relationship with respect to the second type of quasi-co-address parameters.

[0828] Among them, the association between control channel resources satisfying the first characteristic and the second quasi-co-located reference signal set means that:

[0829] Configure the second quasi-co-location reference signal set in the configuration information of control channel resources that satisfy the first feature;

[0835] Alternatively, the association between the fourth QCL reference signal set and the fifth quasi-co-located reference signal set can be determined by predetermined rules.

[0836] In embodiments of the present invention, the control channel resource group satisfies at least one of the following:

[0837] Different control channel resources in different control channel resource groups can be received simultaneously by the communication node;

[0838] Different control channel resources in the same control channel resource group cannot be received by the communication node at the same time;

[0839] x1 control channel resources in the same control channel resource group can be received simultaneously by the communication node, where x1 is a positive integer less than or equal to x2, and x2 is the number of control channel resources included in the control channel resource group;

[0840] For example, a downlink control channel resource group corresponds to a receiving panel of a communication node. Control channel resources in different control channel resource groups can be received by the communication node simultaneously, and generally, the beam isolation between different panels is relatively high. Different control channel resources in the same control resource group cannot be received by the communication node simultaneously, that is, in this case, a panel has only one radio frequency link, and a radio frequency link can only generate one radio frequency beam at a time. Of course, a panel can also correspond to multiple radio frequency links, so there can be x1 control channel resources in a control channel resource group that can be received by the communication node simultaneously, where x1 is a positive integer less than or equal to x2, and x2 is the number of control channel resources included in the control channel resource group.

[0841] M is a positive integer less than or equal to M²;

[0842] M is a positive integer less than or equal to M3;

[0843] M2 is equal to M3.

[0844] In embodiments of the present invention, the control channel resource group satisfies at least one of the following:

[0845] Different control channel resources in different control channel resource groups can be received simultaneously by the communication node;

[0846] Different control channel resources in the same control channel resource group cannot be received by the communication node at the same time;

[0847] x1 control channel resources in a control channel resource group can be received simultaneously by a communication node; where x1 is a positive integer less than or equal to x2, and x2 is the number of control channel resources included in the control channel resource group;

[0848] M is a positive integer less than or equal to M²;

[0849] M is a positive integer less than or equal to M3;

[0850] M2 is equal to M3;

[0851] The intersection of the resources occupied by the control channels in different control channel resource groups is empty;

[0852] The communication node is the communication node that receives the control channel resource group.

[0853] The aforementioned communication node (such as a terminal) is the communication node that receives the control channel resource group.

[0854] In this embodiment of the invention, a type of QCL parameter refers to at least one QCL parameter.

[0855] In this embodiment of the invention, the port can be a DMRS port or a measurement reference signal port.

[0856] When selecting control channel resources as described above, it is equivalent to PDSCH1 and PDSCH2 selecting control channel resources in the same control channel resource group. The following describes another method for selecting control channel resources: PDSCH1 selects control channels from the control channel resource group corresponding to PDSCH1, and PDSCH2 selects control channels from the control channel resource group corresponding to PDSCH2.

[0857] For example, as shown in Figure 3(c), the control channel resource group corresponding to PDSCH1 is group 1 {CORESET0, CORESET1, CORESET2}, and the control channel resource group corresponding to PDSCH2 is group 2 {CORESET3, CORESET4, CORESET5}. When the interval between DCI1 and PDSCH1 is less than K, N4 control channel resources are selected from the slot closest to PDSCH1 within the slot containing at least one control channel resource from control channel resource group 1. Based on these N4 control channel resources, a set of QCL reference signals for N4 DMRS groups of PDSCH1 is obtained, where one DMRS group corresponds to one set of QCL reference signals. Alternatively, a set of QCL reference signals for PDSCH1 with fewer than N4 DMRS groups is obtained based on the N4 control channel resources, where one DMRS group corresponds to more than one set of QCL reference signals.

[0858] For example, as shown in Figure 3(c), both PDSCH1 and PDSCH2 are in slot(n). Among the slots of CORESET in control channel resource group 1, the slot closest to PDSCH1 is slot(n-1). Thus, the QCL reference signal set of PDSCH1 is the QCL reference signal set of the demodulation reference signal of CORESET1 with the lowest CORESETID in {CORESET1, CORESET2} in slot(n-1).

[0859] In the control channel resource group 2, the slot closest to PDSCH2 in the CORESET slot is slot (n-2). Therefore, the QCL reference signal set for PDSCH2 is the set of demodulated reference signals of CORESET3 with the lowest CORESETID within {CORESET3, CORESET4} in slot (n-2). Optionally, PDSCH1 and PDSCH2 belong to the same carrier member (CC), or they fall within the same bandwidth part (BWP).

[0860] The aforementioned port group corresponds to one control channel resource group. However, this embodiment of the invention does not exclude the possibility of one port group corresponding to multiple control channel resource groups. For example, if a port group is transmitted in multiple time units, the port group in each time unit corresponds to one control channel resource group. One control channel resource group can also correspond to one or more port groups. For instance, a PDSCH includes two DMRS groups, and the QCL reference signal set in the two DMRS groups is the set of QCL reference signals for selecting two control channel resources from one control channel resource group corresponding to the PDSCH. The method for selecting N4 control channel resources from one control channel resource group can be similar to methods one through four described above for selecting N2 control channel resources, except that N4 control channel resources are selected from one control channel resource group.

[0861] The following section details how to obtain the correspondence between port groups and control channel resource groups.

[0862] Method 1 for determining the correspondence between port groups and control channel resource groups: The configuration information of the data channel includes the configuration information of the control channel resource group corresponding to the data channel. For example, the configuration information of the PDSCH includes the configuration information of the CORESET group corresponding to the PDSCH. Then the port group included in this data channel corresponds to the control channel resource group configured in this data channel.

[0863] For example, the transmission parameters of PDSCH are configured in the higher-layer signaling, and the corresponding CORESET group of PDSCH is also configured. DCI dynamically schedules PDSCH. Some transmission parameters of the dynamically scheduled PDSCH are obtained according to the transmission parameters of PDSCH configured in the higher-layer signaling. The dynamically scheduled PDSCH may include one demodulation reference signal port group or two demodulation reference signal port groups. The control channel resource group corresponding to all demodulation reference signal port groups included in the dynamically scheduled PDSCH is the CORESET group included in the higher-layer signaling configuration of PDSCH.

[0864] Method 2 for determining the correspondence between port groups and control channel resource groups: Configure the index of the control channel resource group in the configuration information of the control channel resource. If there is no index of the control channel resource group in the configuration information of a control channel resource, the control channel resource is defaulted to the first group.

[0865] For example, the CORESET group ID can be configured in the CORESET configuration information. If the CORESET configuration information does not include the CORESET group ID, the default is that the CORESET belongs to the first CORESET group.

[0866] Alternatively, configure a control channel resource group, wherein the configuration information of the control channel resource group includes the configuration information of the control channel resources included in the control channel resource group.

[0867] Among them, the CORESET group corresponding to a port group is the CORESET group to which the DCI of the channel or signal corresponding to the port group belongs.

[0868] Method 3 for determining the correspondence between port groups and control channel resource groups: The control channel resource group corresponding to a port group is the predetermined CC or the control channel resources in the predetermined CC group.

[0869] Among them, the reserved CC or reserved CC group corresponding to a port group is obtained according to signaling information or agreed rules.

[0870] For example, a port group corresponds to any of the following CC / CC groups:

[0871] The CC of the lowest CCID in the most recent time unit of the channel or signal corresponding to the port group / the CC group to which that CC belongs;

[0872] The CC where the channel or signal corresponding to the port group is located / the CC group to which the CC is located;

[0873] The CC where the DCI of the channel or signal corresponding to the scheduling port group is located / the CC group to which the CC is located.

[0874] Different CCs can be represented by different serving cells.

[0875] For example, when there are multiple CCs, it is necessary to determine the control channel resource group corresponding to the port group, select a control channel resource in the control channel resource group, and obtain the QCL reference signal of the port group based on the selected control channel resource. The control channel resource group is determined based on at least one of the CC information mentioned above.

[0876] In this embodiment of the invention, determining at least M quasi-co-location reference signal sets for M port groups based on N2 control channel resources includes:

[0877] The quasi-co-location reference signal set of any one of the M port groups is determined based on the configuration information of at least one of the N2 control channel resources, where M is a positive integer less than or equal to N2.

[0878] Alternatively, the quasi-co-location reference signal set of any one of the M port groups is determined based on the quasi-co-location reference signal set of the demodulation reference signal of at least one of the N2 control channel resources.

[0879] exist Figure 1 In this embodiment, there is no ideal backhaul link between TRP1 and TRP2. Of course, this embodiment does not exclude the possibility that there is an ideal backhaul link between TRP1 and TRP2.

[0880] In the above embodiments, two or more TRPs serving the UE send both control channels and data channels. When some TRPs among the two or more TRPs serving the UE send both control channels and data channels, while some TRPs only send data channels, the solution in the above embodiments is not applicable.

[0881] For example, such as Figure 4 As shown, there is an ideal backhaul between TRP1 and TRP2. TRP1 transmits DMRS group1 of PDSCH and DCI of PDSCH, while TRP2 transmits DMRS group2 of PDSCH. When the time interval between DCI of PDSCH and PDSCH is less than a predetermined threshold K, it is necessary to determine the receiving beams of DMRS group1 and DMRS group2, that is, to determine the QCL reference signal set of DMRS group1 and DMRS group2, or to determine the QCL reference signal set 1 of DMRS group1 that satisfies the QCL relationship with respect to Spatial Rx parameter and the QCL reference signal set 2 of DMRS group2 that satisfies the QCL relationship with respect to Spatial Rx parameter.

[0882] For example, such as Figure 5As shown, there is an ideal backhaul between TRP1 and TRP2. TRP1 transmits PDSCH 1, and TRP2 transmits PDSCH 2. Both DCI1 (scheduling PDSCH 1) and DCI2 (scheduling PDSCH 2) are transmitted on TRP1. When the time interval between DCI1 and PDSCH 1 is less than a predetermined threshold K, and the time interval between DCI2 and PDSCH 2 is less than the predetermined threshold K, it is necessary to determine the receiving beams of PDSCH 1 and PDSCH 2, that is, to determine the QCL reference signal sets of DMRS group1 and DMRS group2, or to determine the QCL reference signal set 1 of DMRS group1 that satisfies the QCL relationship with respect to the Spatial Rx parameter and the QCL reference signal set 2 of DMRS group2 that satisfies the QCL relationship with respect to the Spatial Rx parameter. Here, DMRS group1 is the demodulation reference signal port group included in PDSCH 1, and DMRS group2 is the demodulation reference signal port group included in PDSCH 2; that is... Figure 5 In this embodiment, PDSCH1 and PDSCH2 each include only one DMRS port group. However, this embodiment does not exclude the possibility that PDSCH1 and / or PDSCH2 include two or more DMRS port groups. Optionally, PDSCH1 and PDSCH2 belong to the same CC, or PDSCH1 and PDSCH2 fall within the same BWP.

[0883] See Figure 6 Another embodiment of the present invention proposes a method for determining the QCL reference signal set, comprising:

[0884] Step 600: Determine at least P sets of quasi-co-addressable reference signals for the P-class port group, where P is an integer greater than or equal to 2.

[0885] Specifically, Class P port groups include Class I port groups and Class II port groups;

[0886] The set of at least P quasi-co-address reference signals for determining the P-type port group includes:

[0887] Determine the first quasi-co-address reference signal set for the first type of port group;

[0888] Determine the second quasi-co-address reference signal set for the second type of port group.

[0889] The acquisition methods for the quasi-co-location (QCL) reference signal set of the first type of port group and the second type of port group are different. That is, the first quasi-co-location reference signal set of the first type of port group is determined using a first determination method, and the second quasi-co-location reference signal set of the second type of port group is determined using a second determination method.

[0890] The step of determining the first quasi-co-address reference signal set of the first type of port group using the first determining method includes: determining the first quasi-co-address reference signal set of the first type of port group based on the first type of parameters;

For example, the first type of parameters includes a set of quasi-co-located reference signals for demodulation reference signals of predetermined control line channel resources, wherein the predetermined control channel resource packet is a set of control channel resources that satisfy the first predetermined characteristic and are located in the time unit closest to the channel or signal corresponding to the first type of port group, satisfying the second predetermined characteristic. Alternatively, the predetermined control channel resources are the control channel resources where the DCI scheduling the first type of port is located. The second type of parameters does not include a set of quasi-co-located reference signals for demodulation reference signals of predetermined control channel resources, and can be parameters such as higher-layer signaling notification parameters.

[0950] In another embodiment of the present invention, before determining the first quasi-co-location reference signal set, the method further includes: determining the port group as the first type of port group according to the second control signaling and / or predetermined rules;

[0951] Before determining the second quasi-co-location reference signal set, the method further includes: determining the port group as the second type of port group according to the second control signaling and / or predetermined rules.

[0952] For example, in the second control signaling, the method for determining the QCL reference signal set of a port group is either the first determination method or the second determination method. If it is the first determination method, the port group is determined to be a first type of port group; if it is the second determination method, the port group is determined to be a second type of port group.

[0953] Specifically, at least P sets of quasi-co-address reference signals for the P-type port group are determined based on at least one of the following parameters:

[0954] The maximum number of port groups included in a channel or signal;

[0955] The maximum number of port groups included when the time interval between the control information for scheduling the channel or signal and the channel or signal is less than a predetermined threshold;

[0959] A set of quasi-co-located reference signals for each port group when the interval between the control information for scheduling the channel or signal and the channel or signal is less than a predetermined threshold.

[0960] The channel includes a data channel or a control channel, and the port group of the channel is a demodulation reference signal port group;

[0961] When the signal is a measurement reference signal, the port group of the signal is the measurement reference signal group.

[0962] In this embodiment of the invention, at least one quasi-co-address reference signal set of at least one port group in the Class P port group is determined based on at least one of the following parameter information:

[0963] The maximum number of port groups included in a channel or signal;

[0964] The maximum number of port groups included when the time interval between the control information for scheduling the channel or signal and the channel or signal is less than a predetermined threshold;

[0965] A method for determining the quasi-co-located reference signal set for each port group of a channel or signal;

[0966] A set of quasi-co-located reference signals for each port group of a channel or signal;

[0968] A set of quasi-co-located reference signals for each port group when the interval between the control information for scheduling the channel or signal and the channel or signal is less than a predetermined threshold.

[0969] The parameter information is determined based on signaling information or predetermined rules, wherein the signaling information includes at least one of the following:

[0970] Non-physical layer signaling information;

[0971] High-level signaling information;

[0972] Configure the signaling information of the channel corresponding to the port group;

[0973] Configure the signaling information of the measurement reference signal resources corresponding to the port group;

[0974] Configuration information of the control channel resources where the control information of the channel corresponding to the port group is located;

[0975] The configuration information of control channel resources that meet predetermined characteristics is included in the time unit closest to the channel corresponding to the port group;

[0976] Configuration information of the control channel resources where the control information for the measurement reference signal resources corresponding to the port group is located;

[0977] Configuration information of control channel resources that meet predetermined characteristics, included in the time unit closest to the measurement reference signal resource corresponding to the port group.

[0978] Among them, the port group satisfies at least one of the following characteristics:

[0979] The maximum number of port groups included in a channel or signal is related to the number of control channel resources;

[0980] The maximum number of port groups included in a channel or signal is related to the number of control channel resources when the time interval between the control information for scheduling the channel or signal and the channel or signal is less than a predetermined threshold.

[0981] The maximum number of port groups included in a channel or signal is related to the number of control channel resource groups;

[0982] The maximum number of port groups included in a channel or signal is related to the number of control channel resources when the time interval between the control information for scheduling the channel or signal and the channel or signal is less than a predetermined threshold.

[0983] If two pieces of information are related, it means that one piece of information can be used to obtain the other piece of information, or to obtain the range of values ​​for the other piece of information.

[0984] Assume that the number of control channel resources is B, where B is an integer greater than or equal to 1, and the B control channel resources satisfy at least one of the following characteristics:

[0985] The B control channel resources belong to one BWP, the B control channel resources are dedicated control channel resources, and the demodulation reference signals of the B control channel resources have different QCL reference signal sets.

[0986] in,

[0987] A Class P port group corresponds to one or more data channels with P demodulation reference signal port groups.

[0988] Alternatively, the P-type port group corresponds to P measurement reference signal port groups of one or more measurement reference signal resources;

[0989] Alternatively, some port groups in the P-type port group may correspond to one or more demodulation reference signal port groups for data channels, and some port groups may correspond to one or more measurement reference signal port groups.

[0990] The port group satisfies at least one of the following:

[0991] The time interval between the channel or signal and the control signaling that schedules the channel or signal is less than a predetermined threshold;

[0992] The time interval between the channel or signal and the control channel that schedules the channel or signal is less than a predetermined threshold;

[0993] The control signaling for scheduling the channel or signal does not include notification information for the quasi-co-address reference signal set of the port group;

[0994] The signal is a periodic signal;

[0995] The signal is a half-cycle signal;

[0996] The channel is a half-cycle scheduling channel;

[0997] The channels corresponding to the Class P port groups are received in the same time unit;

[0998] The measurement reference signal resources corresponding to the P-type port group are received in the same time unit;

[0999] The channels corresponding to the Class P port groups are received at the same time.

[1000] The measurement reference signal resources corresponding to the P-type port group are received at the same time;

[1001] The channel or signal is a channel or signal corresponding to at least one port group in the port group.

[1002] In this document, different ports in different port groups do not satisfy QCL relationships, while ports in the same port group satisfy QCL relationships with respect to at least one QCL parameter.

[1003] The method for obtaining the QCL reference signal set of the first type of port group is different from the method for obtaining the QCL reference signal set of the second type of port group.

[1004] For example, the QCL reference signal set of the first type of port group is the QCL reference signal set of the demodulation reference signal of a control channel resource, while the QCL reference signal set of the second type of port group is not obtained based on the QCL reference signal set of the demodulation reference signal of a control channel resource. Figure 4 DMRS group2 or Figure 5 The DMRS group included in PDSCH2 is not the same as the QCL reference signal set of any control channel resource group's demodulation reference signal because TRP2 does not transmit PDCCH.

[1005] The method for obtaining the QCL reference signal set of the second type of port group may include at least one of the following methods:

[1006] Method 1: Determination of the QCL reference signal set for the second type of port group in higher-layer signaling configuration.

[1007] For example, in the higher-layer signaling of PDSCH, when the time interval between DCI and PDSCH is less than K, PDSCH includes the QCL reference signal set of DMRS group2, and the QCL reference signal set of DMRS group1 is the QCL reference signal set containing the demodulated reference signal of CORESET with the lowest CORESETID in the slot closest to PDSCH, such as... Figure 4 As shown.

[1008] Alternatively, the method for determining the QCL reference signal set for each DMRS group in all DMRS groups included in the PDSCH can be configured in the higher-layer signaling of the PDSCH when the time interval between the DCI and the PDSCH is less than K.

[1009] When the time interval between the DCI that schedules the PDSCH and the PDSCH is greater than K, the QCL reference signal set of the port group of the PDSCH is determined according to the TCI field indicated in the DCI, and not according to the QCL reference signal set of the port group configured in the higher-layer signaling.

[1010] To implement the above method, at least one of the following parameters can be obtained through signaling information or predetermined rules:

[1011] Parameter 1: The maximum number of port groups included in the channel or signal.

[1012] For example, the maximum number of demodulation reference signal port groups included in the PDSCH can be further configured in the higher-layer signaling information of the PDSCH, that is, the number of demodulation reference signal port groups included in the PDSCH indicated in the DCI does not exceed the maximum value configured in the higher-layer signaling.

[1013] When the maximum number of port groups is greater than 1, the QCL reference signal of DMRS group1 by default is obtained from the set of QCL reference signals of the demodulation reference signals of the control channel resource with the lowest control channel resource identifier in the control channel resource group that the terminal needs to detect in the predetermined time unit. The predetermined time unit is the time unit closest to the PDSCH among the time units containing the control channel resource to be detected. Further, when configuring other DMRS groups (excluding DMRS group1) where the interval between the DCI and PDSCH of the PDSCH scheduling is less than K, the acquisition method of the QCL reference signal set for other DMRS groups, or the QCL reference signal set of other DMRS groups, is specified.

[1014] Alternatively, the higher-layer signaling configures the QCL reference signal set for each of the x3 port groups when the time interval between DCI and PDSCH is less than K, where x3 is the maximum number of port groups included in PDSCH.

[1015] For example, configure the following information in the higher-level signaling configuration of PDSCH.

[1016] For example, the following configuration can be made in the higher-layer signaling of PDSCH: in this article, different DMRS ports in one DMRS group satisfy the QCL relationship, while DMRS ports in different DMRS groups do not satisfy the QCL relationship.

[1017] PDSCH-Config::=SEQUENCE{

[1018] ......,

[1019] The maximum number of DMRS groups included in PDSCH (say, 2) is optional.

[1020] When the interval between the DCI and PDSCH of the PDSCH scheduling is less than K, the acquisition method of the QCL reference signal set of DMRS group1 is optional.

[1021] When the interval between the DCI and PDSCH of the PDSCH scheduling is less than K, the acquisition method of the QCL reference signal set of DMRS group2 is: optional};

[1022] Alternatively, configure it as follows in the higher-level signaling of PDSCH:

[1023] PDSCH-Config::=SEQUENCE{

[1024] ......,

[1025] The maximum number of DMRS groups included in PDSCH (say, 2), optional;

[1026] When the interval between the DCI and PDSCH of the PDSCH scheduling is less than K, the QCL reference signal set of DMRS group2; optional};

[1027] Parameter 2: The maximum number of port groups included when the time interval between the control information for scheduling the channel or signal and the channel or signal is less than a predetermined threshold.

[1028] For example, when the time interval between DCI and PDSCH is less than K, the number of port groups included in the PDSCH scheduled in DCI cannot exceed the maximum number of port groups. When the time interval between DCI and PDSCH is greater than or equal to K, the number of port groups included in the PDSCH scheduled in DCI cannot exceed the predetermined maximum number of port groups. For example, it is agreed that the maximum number of DMRS groups that a PDSCH can include is 2. When the time interval between DCI and PDSCH is less than a predetermined threshold, the maximum number of DMRS port groups included in the PDSCH scheduled in DCI is 1. When the time interval between DCI and PDSCH is greater than or equal to the predetermined threshold, the maximum number of DMRS port groups included in the PDSCH scheduled in DCI is 2. In short, the maximum number of DMRS port groups that the PDSCH corresponding to this higher-layer configuration information can include when the time interval between DCI and PDSCH is less than the predetermined threshold and the maximum number of DMRS port groups that the PDSCH corresponding to this higher-layer configuration information can include when the time interval between DCI and PDSCH is greater than or equal to the predetermined threshold can be different. The maximum number of port groups included when the time interval between the control channel that schedules the channel or signal and the channel or signal is less than a predetermined threshold can be a predetermined value, such as 1, or it can be included in the higher-layer signaling configuration information of the PDSCH.

[1038] When the interval between the DCI and PDSCH of the PDSCH scheduling is less than K, the acquisition method of the QCL reference signal set of DMRS group2 is: optional}.

[1039] Alternatively, configure it as follows in the higher-level signaling of PDSCH:

[1044] Parameter 3: The method for determining the quasi-co-located reference signal set for each port group of the channel or signal.

[1045] For example, is the configuration of each port group determined by a first determination method or a second determination method? In the first determination method, the QCL reference signal set of the port group is the QCL reference signal set of the demodulation reference signals of the control channel resources that meet the specific characteristics mentioned above; in the second determination method, the QCL reference signal set of the port group is not the QCL reference signal set of the demodulation reference signals of the control channel resources that meet the specific characteristics mentioned above, for example, it can be obtained according to the quasi-co-location reference signal set configured in the higher-layer signaling in the PDSCH mentioned above.

[1046] Parameter 4: The set of quasi-co-address reference signals for each port group of the channel or signal, so that the TCI field may not be included in the DCI. The set of quasi-co-address reference signals for each port group is explicitly configured by higher-layer signaling or obtained through predetermined rules.

[1047] Parameter 5: A method for determining the quasi-co-addressable reference signal set for each port group when the interval between the control information for scheduling the channel or signal and the channel or signal is less than a predetermined threshold. For example, the determination method may include the first determination method and the second determination method described above.

[1048] Parameter 6: The set of quasi-co-addressable reference signals for each port group when the interval between the control information for scheduling the channel or signal and the channel or signal is less than a predetermined threshold.

[1049] The above information is communicated via higher-layer signaling or previous physical layer control signaling. When the interval between the control information of the scheduling channel or signal and the channel or signal is greater than or equal to a predetermined threshold, the quasi-co-addressable reference signal set for each port group is obtained according to the TCI field notified in the DCI, and is no longer obtained according to any one of the parameters one through six mentioned above. Of course, when the DCI does not include the TCI field, even if the interval between the control information and the channel or signal is greater than or equal to the predetermined threshold, it can still be determined according to the parameters one through six mentioned above. The method for determining the QCL reference signal set of DMRS group2 or PDSCH2 mentioned above corresponds to the second determination method.

[1050] The channel or signal is a channel or signal corresponding to at least one port group in the P-type port group.

[1051] The second method for obtaining the QCL reference signal set of the second type of port group is to obtain the QCL reference signal set of the second type of port group through the fourth quasi-co-located reference signal set (also referred to as the fourth QCL reference signal set) associated with a control channel resource. The fourth quasi-co-located reference signal set is not the seventh quasi-reference signal of the demodulation reference signal of the control channel resource.

[1052] For example, CORESET's configuration information includes the following:

[1053] ControlResourceSet::= SEQUENCE{

[1054] controlResourceSetId 1; (i.e., this CORESET is CORESET1) ......

[1056] tci-StatesPDCCH SEQUENCE (SIZE)

[1057] (1..maxNrofTCI-StatesPDCCH))OF TCI-StateId OPTIONAL,

[1058] (The seventh QCL reference signal set used to configure the demodulation reference signal of this Control Resource Set, i.e., CORESET)

[1059] tci-StatesPDSCH SEQUENCE(SIZE(1..maxNrofTCI-StatesPDCCH))OF TCI-StateId OPTIONAL, (used to configure the fourth QCL reference signal set mentioned above)

[1060] }

[1061] One point needs clarification: the above configuration information can be a MAC-CE signaling, which simultaneously activates tci-StatesPDCCH and tci-StatesPDSCH, both of which originate from a TCI state pool configured by the PDCCH Radio Resource Control (RRC); or the above signaling can be RRC signaling, which configures the two TCI state pools tci-StatesPDCCH and tci-StatesPDSCH, and the MAC-CE signaling further activates one TCI state for each of tci-StatesPDCCH and tci-StatesPDSCH.

[1062] Specifically, when the interval between PDSCH and DCI is less than K, and the CORESET with the lowest CORESETID in the slot closest to PDSCH is the CORESET configured above, the QCL reference signal set of DMRS group 1 for this PDSCH is obtained based on the QCL reference signal set of the demodulated reference signal of the aforementioned CORESET, i.e., based on the information configured in tci-StatesPDCCH 1. The QCL reference signal set of DMRS group 2 is obtained based on the tci-StatesPDSCH in the aforementioned CORESET.

[1063] The QCL reference signal set configured in section 1 is obtained.

[1064] like Figure 7 As shown, in slot(n), CORESET1 is in the first 3 time domain symbols, and PDSCH is in the later time domain symbols. The time interval between the DCI and PDSCH of the PDSCH is less than a predetermined threshold K. When the terminal receives PDSCH, it uses the receive beam 1 obtained according to the information configured by tci-StatesPDCCH to receive CORESET, uses the receive beam 1 to receive DMRS group 1 of PDSCH, and uses the receive beam 2 obtained according to the information configured by tci-StatesPDSCH to receive DMRS group 2 of PDSCH.

[1065] Optionally, tci-StatesPDSCH can be related to time-domain sets, with different time-domain sets corresponding to different tci-StatesPDSCH configurations.

[1066] For example, in the time unit closest to PDSCH1, the CORESET with the lowest CORESETID in slot n is CORESET1 (that is, the CORESET1 configured in the above configuration information). The TCI state1 corresponding to CORESET1 in slot (n) is beam 2, and beam 2 is used to receive DMRS group2 of PDSCH1. In the time unit closest to PDSCH2, the CORESET with the lowest CORESETID in slot (n+10) is CORESET1. The TCI state2 corresponding to CORESET1 in slot n+10 is beam 3, and beam 3 is used to receive DMRS group2 of PDSCH2.

[1067] exist Figure 7 The two methods used to obtain the QCL reference signal set are different for different DMRS groups of the same PDSCH. Figure 5 In the process, TRP1 sends DCI1 and DCI2, PDSCH1, and TRP2 sends PDSCH2. DCI1 schedules PDSCH1, and DCI2 schedules PDSCH2.

[1068] When the time interval between DCI1 and PDSCH1 is less than K, the QCL reference signal set of PDSCH1 is obtained based on the QCL reference signal set of the demodulated reference signal with the lowest CORESETID in the time unit closest to PDSCH1 (for example, time unit 1). (i.e., the seventh QCL reference signal set, or the QCL reference signal set configured by tci-StatesPDCCH above).

[1069] The QCL reference signal set of the demodulation reference signal of PDSCH2 is obtained from the CORESET (if it is the CORESET configured above) with the lowest CORESETID in the time unit closest to PDSCH2 (if it is time unit 2).

[1070] The time unit 1 and time unit 2 mentioned above can be the same time unit or different time units.

[1071] The tci-StatesPDSCH can correspond to different QCL reference signal sets in different time domain sets. For example, when CORESET falls in the first time domain set, the QCL reference signal set of PDSCH2 is reference signal set 1; when CORESET falls in the second time domain set, the QCL reference signal set of PDSCH2 is reference signal set 2.

[1072] Furthermore, when the DCI in CORESET1 can be scheduled across CCs, the tci-StatesPDSCH in CORESET1 should correspond to multiple CCs, each corresponding to one of the multiple CCs that CORESET1 can schedule. This ensures that when the terminal is buffering, for each CC's PDSCH, when the interval between the DCI and PDSCH is less than K, the quasi-co-address reference signal set of the DMRSgroup2 or DMRS of PDSCH2 in that CC is used. Alternatively, tci-StatesPDSCH can only be configured with quasi-co-address reference signals associated with spatial reception filtering parameters. In this way, even if CORESET1 can schedule PDSCH / CSI-RS in multiple CCs, but only one quasi-co-address reference signal is configured in tci-StatesPDSCH, the spatial reception filtering parameters of multiple CCs can all use a single quasi-co-address reference signal. The quasi-co-address reference signals for other QCL parameters of the PDSCH in each CC can be obtained from the DCI or the higher layers in each CC.

[1073] Furthermore, the PDSCH configuration information needs to be configured to determine whether, when the time interval between DCI and PDSCH is less than K, the QCL reference signal set of the demodulation reference signal of PDSCH is obtained based on the tci-StatesPDCCH configured in the CORESET with the lowest CORESETID in the time unit closest to the PDSCH (corresponding to the first determination method), or based on the tci-StatesPDSCH configured in the CORESET with the lowest CORESETID in the time unit closest to the PDSCH (corresponding to the second determination method).

[1074] The above configuration includes tci-StatesPDCCH and tci-StatesPDSCH. Alternatively, a TCI state of tci-StatesPDCCH can include two QCL reference signal sets. The first QCL reference signal set is the QCL reference signal set of the demodulation reference signal of the CORESET (i.e., the seventh QCL reference signal set). When the interval between a PDSCH and the DCI that schedules the PDSCH (more precisely, the PDCCH that schedules the PDSCH) is less than K, and the CORESET with the lowest CORESETID in the nearest slot of the PDSCH that includes the CORESET is the aforementioned CORESET, the quasi-co-located reference signal set of the demodulation reference signal of the PDSCH is obtained according to the second QCL reference signal set included in the TCI state of the tci-StatesPDCCH, or the quasi-co-located reference signal set of the second demodulation reference signal group of the PDSCH is obtained according to the second QCL reference signal set included in the TCI state.

[1075] In the above embodiments, the method for determining the QCL reference signal set of a port group is applicable when the time interval between the control information (DCI) scheduling the channel or signal corresponding to the port group and the channel or signal is less than a predetermined threshold. Of course, the method for obtaining the QCL reference signal set of a port group described herein is also applicable when the control information scheduling the channel or signal corresponding to the port group does not include the QCL reference signal set of the port group. That is, the dynamic signaling does not include the TCI field, meaning the dynamic control signaling does not notify the method for determining the QCL reference signal set of the demodulation reference signal. For example, it could be DCI1_0, or the CORESET containing DCI1_1 is configured such that the DCIs included in this CORESET do not include the TCI field. Optionally, when the DCIs do not include the TCI field, and the interval between the DCI and PDSCH is greater than a predetermined threshold, the first time unit or the second time unit is the time unit where the DCI is located, or multiple time units closest to the DCI, wherein the N2 control channel resources include the control channel resources where the DCI is located. For example, PDSCH includes two DMRS groups. DMRS group 1 is determined based on the QCL reference signal of the demodulation reference signal of the CORESET where DCI1 is located. The quasi-co-located reference signal set of DMRS group 2 can be determined according to the above method for determining the quasi-co-located reference signal of DMRS group 2. Here, DCI1 is the DCI that schedules the PDSCH. The quasi-co-located reference signal set of DMRS group 2 can also be determined according to one of the following methods:

[1076] Method 1: Obtain the quasi-co-address reference signal set based on the demodulation reference signal of the lowest CORESETID among the CORESETs other than CORESET1 in the nearest time unit where DCI1 is located, where CORESET1 is the CORESET where DCI is located;

[1077] Method 2: Determine the quasi-co-located reference signal set based on the demodulation reference signal of the lowest CORESETID in the CORESET group (excluding the CORESET group where CORESET1 is located) in the nearest time unit where DCI1 is located, where CORESET1 is the CORESET where DCI is located;

[1078] Method 3: Obtain the QCL reference signal set of DMRS group2 according to the tci-StatesPDSCH configured in the CORESET where the control channel of DCI1 is located, or obtain the QCL reference signal set of DMRS group2 according to the second QCL reference signal set configured in the tci-StatesPDCCH of the CORESET where the control channel of DCI1 is located.

[1079] In this article, the CORESET where DCI is located, that is, the CORESET where PDCCH including DCI is located, is the interval between DCI / control signaling and PDCCH for scheduling PDSCH / AP-CSI-RS. More precisely, it should be the interval between PDCCH and PDCCH for scheduling PDSCH / AP-CSI-RS. DCI includes the transmission parameters for scheduling PDSCH / AP-CSI-RS. DCI channel is encoded and transmitted in PDCCH. The control signaling can correspond to the control channel.

[1080] The demodulation reference signal of a CORESET as described in this article refers to the demodulation reference signal of the DCI transmitted in this CORESET, or the demodulation reference signal of the PDCCH transmitted in this CORESET.

[1081] In the above embodiments, a QCL reference signal set for a target reference signal means that the target reference signal and the reference signals in the QCL reference signal set satisfy a QCL relationship with respect to a class of QCL parameters. Two reference signals satisfying a QCL relationship with respect to a class of QCL parameters indicates that the QCL parameters of one reference signal can be obtained from the QCL parameters of the other reference signal. The class of QCL parameters includes at least one of the following parameters: Doppler shift, Doppler spread, average delay, delay spread, and Spatial Rxparameter.

[1082] In this document, the signal includes at least one of the following signals:

[1083] Demodulation reference signal, measurement reference signal, synchronization signal, phase tracking reference signal (PTRS), tracking reference signal (TRS).

[1084] The channel includes at least one of the following channels:

[1085] Physical Downlink Shared Channel (PDSCH), Physical Downlink Control Channel (PDCCH), Physical Uplink Shared Channel (PUSCH), and Physical Uplink Control Channel (PUCCH).

[1194] The time interval between the channel or signal and the control channel that schedules the channel or signal is less than a predetermined threshold;

[1195] The control signaling for scheduling the channel or signal does not include notification information for the quasi-co-address reference signal set of the second type of port group;

[1196] The signal is a periodic signal;

[1197] The signal is a half-cycle signal;

[1198] The channel is a half-cycle scheduling channel;

[1199] The channel or signal is a channel or signal corresponding to at least one port group in the second type of port group.

[1200] The method for determining the second QCL reference signal set of the second type of port group in this embodiment is similar to the method for determining the QCL reference signal set of the P type port group in the previous embodiment, and will not be repeated here.

[1201] See Figure 8 Another embodiment of the present invention proposes a method for determining a QCL reference signal set, comprising:

[1202] Step 800: Determine the set of quasi-co-located reference signals;

[1203] Step 801: Transmit channels or signals on the corresponding resources according to the quasi-co-location reference signal set.

[1204] In this embodiment of the invention, one resource corresponds to A sets of quasi-co-location reference signals;

[1205] Wherein, the reference signal in each of the A quasi-co-address reference signal sets and the resource have a quasi-co-address relationship with respect to a class of quasi-co-address parameters, and A is an integer greater than or equal to 1.

[1206] The resource includes any of the following:

[1207] One demodulation reference signal port resource, one measurement reference signal port resource, one control channel resource, and one data channel resource.

[1208] In this embodiment of the invention, a channel or signal is transmitted on a corresponding resource according to the quasi-co-location reference signal set; or, a channel or signal is received on a corresponding resource according to the quasi-co-location reference signal set.

[1209] In this embodiment of the invention, the set of A quasi-co-located reference signals corresponding to one resource includes:

[1210] The A sets of quasi-co-located reference signals include a first set of quasi-co-located reference signals and a second set of quasi-co-located reference signals;

[1211] Among them, the difference between the first quasi-co-address parameter set associated with the first quasi-co-address reference signal set and the second quasi-co-address parameter set associated with the second quasi-co-address reference signal set is an empty set.

[1212] The first quasi-co-address parameter set and the second quasi-co-address parameter set include at least one of the following parameters: Doppler shift, Doppler spread, multipath delay, multipath spread, and spatial reception parameters.

[1213] In this embodiment of the invention, the A1 frequency domain resource sets of a resource correspond to A1 quasi-co-located reference signal sets;

[1214] The A2 time-domain resource sets of a resource correspond to A2 quasi-co-located reference signal sets;

[1215] Where A1 and A2 are positive integers less than or equal to the value of A.

[1216] like Figure 9 The method shown assumes an ideal backhaul between TRP1 and TRP2. To increase the robustness of the PDCCH, both TRP1 and TRP2 can transmit the same DCI, resulting in the following scheme:

[1217] Option 1: A PDCCH's DMRS is associated with multiple QCL reference signal sets. The difference between the QCL parameter sets associated with these multiple QCL reference signal sets is empty, meaning the QCL parameter sets associated with these multiple QCL reference signal sets are the same. In this case, two beams are used to transmit the same PDCCH on the same time-frequency resources.

[1218]

[1219] Table 1

[1220] Table 1 shows that one DMRS group corresponds to two sets of QCL reference signals.

[1221] Option 2: Different time domains of a CORESET correspond to different sets of QCL reference signals. For example, the same CORESET may correspond to different sets of QCL reference signals in different slots, or the same CORESET may correspond to different sets of QCL reference signals in different time domain symbol sets in the same slot. In this case, the same PDCCH may be transmitted using different beams on different time domain resources.

[1222] Option 3: Different frequency domains of a CORESET correspond to different sets of QCL reference signals. For example, the first set of Physical Resource Blocks (PRBs) of the same CORESET corresponds to the first set of QCL reference signals, and the second set of PRBs of the same CORESET corresponds to the second set of QCL reference signals. In this case, the same PDCCH uses different beams to transmit on different frequency domain resources.

[1223] Option 4: Configure two CORESETs, each corresponding to a QCL reference signal set, and then configure these two CORESETs to have different transmissions for the same PDCCH.

[1224] Optionally, both CORESETs can agree to always use the same aggregation degree for the same PDCCH.

[1225] Different slots correspond to different sets of QCL reference signals, or the same CORESET corresponds to different sets of QCL reference signals in different time-domain symbol sets in the same slot.

[1226] In this paper, a port group, also known as a quasi-co-located port group, has reference signals that satisfy the QCL relationship, while reference signals in different port groups do not satisfy the QCL relationship.

[1227] In this embodiment of the invention, when the time interval between the channel or signal and the control signaling of the scheduling channel or signal is less than a predetermined threshold, or the control signaling of the scheduling channel or signal does not include notification information of the QCL reference signal set of the port group, or the channel is SPS-PDSCH, or the signal is a periodic signal or a half-periodic signal, the above method solves the signal reception problem and improves the success rate of signal reception.
