Since the various association relationships of the channels are configured and associated through the channel resources of the channels, in the following description, the first set to which the channel resources of the channels belong is preferentially described by taking the first set to which the channel belongs as an example, that is, the first set to which the channel belongs or the first set to which the channel resources of the channels belong may be replaced in the embodiment of the present application.

Embodiment 2.2 determines the CORESET associated with the PDCCH carrying the DCI; based on the determined CORESET, a first set to which each or each pair of TCI states belongs is determined.

In this communication method 200, the terminal device can learn the association relationship between each or each pair of TCI states and the first set, so as to be beneficial to combining the association relationship between the channel or signal and the first set, and learn the TCI state associated with the channel or signal, thereby implementing reliable channel or signal transmission in the multi-TRP collaboration scenario.

In an alternative embodiment, the terminal device may receive the first information of the channel or signal from the network device. In another alternative embodiment, the terminal device may determine the first information of the channel or signal according to the network configuration information. Further, the manner of acquiring the first information can be specifically described in connection with the following embodiments 1.1 to 1.4, respectively.

S102, the terminal equipment determines a first set of channel resources of a channel or a first set of resource sets of signals according to the first information.

In embodiment 1.1, the first information is a channel or signal associated CORESET, as described above.

Alternatively, the channel may be at least one of: PDCCH, PDSCH, PUSCH, PUCCH.

Alternatively, the signal may be an AP CSI-RS. Alternatively, the AP CSI-RS may be an AP CSI-RS for beam management, or may be an AP CSI-RS for CSI acquisition.

Optionally, in the case that the channel is PDSCH or PUSCH, the CORESET associated with the channel is CORESET associated with the PDCCH of the scheduling or activating channel, and accordingly, the terminal device may determine the CORESET associated with the channel according to the CORESET associated with the PDCCH of the scheduling or activating channel. For example, the PUSCH-associated CORESET is the PDCCH-associated CORESET that schedules the PUSCH. For another example, the CORESET associated with the PDSCH is the CORESET associated with the PDCCH on which the PDSCH is scheduled. For another example, the core associated with the PUCCH may be the core associated with the PDCCH that triggered or scheduled the PUCCH.

The core associated with the PDCCH is the core configured by the search space including the PDCCH. For example, the CORESET of search space configurations including the first PDCCH includes the first CORESET, and then the CORESET associated with the first PDCCH is the first CORESET.

Alternatively, where the signal is a CSI-RS, the CORESET associated with the CSI-RS may be a CORESET associated with a PDCCH that schedules or triggers the CSI-RS.

In this embodiment, as in embodiment 3.1, the first set is a CORESET group, that is, different CORESET groups represent different TRPs, and then the first set of channel resources of the channel is a CORESET group to which a CORESET associated with the channel belongs, or the first set of resource sets of the signal is a CORESET group to which a CORESET associated with the signal belongs. That is, the TRP to which the channel resource of the channel belongs is the TRP represented by the CORESET to which the CORESET associated with the channel belongs, or the TRP to which the resource set of the signal belongs is the TRP represented by the CORESET to which the CORESET associated with the signal belongs.

Optionally, the different CORESET groups are CORESET sets associated with different control resource set pool indices. For example, CORESET 1 may be a CORESET set associated with a control resource set pool index coresetpolindex=0, and CORESET 2 may be a CORESET set associated with coresetpolindex=1.

Optionally, the network device may send parameter configurations of CORESETs, where each CORESET parameter configuration is used to configure a CORESET group to which the CORESET belongs; the terminal device may receive the parameter configuration of each CORESET, so as to obtain the CORESET group to which each CORESET belongs.

Optionally, the channel is at least one of: PDCCH, PDSCH, PUSCH, PUCCH; alternatively, the signal may be an aperiodic CSI-RS, which may be an aperiodic CSI-RS used for beam management or an aperiodic CSI-RS used for CSI acquisition.

In an alternative embodiment, if the first set is a CORESET set as in embodiment 3.1, i.e. different CORESET groups represent different TRPs, then the first set to which the channel resources of the channel belong is the CORESET group associated with the channel resource group to which the channel resources of the channel belong, or the first set to which the resource set of the signal belongs is the CORESET group associated with the resource set of the signal. That is, the TRP to which the channel resource of the channel belongs is the TRP represented by the CORESET group associated with the channel resource group to which the channel resource of the channel belongs, or the TRP to which the resource set of the signal belongs is the TRP represented by the CORESET group associated with the resource set of the signal.

Alternatively, the association between each channel resource group or each resource set and each CORESET group may be predefined, such as channel resource group 1 or resource set 1 being associated with CORESET group 1, and channel resource group 2 or resource set 2 being associated with CORESET group 2. Alternatively, the association between each channel resource group or each resource set and each CORESET group is configured in advance, for example, channel resource group 1 or resource set 1 is associated with CORESET group 2, and channel resource group 2 or resource set 2 is associated with CORESET group 1.

In another alternative embodiment, if the first set is SRS resource set as in embodiment 3.2, that is, different SRS resource sets represent different TRPs, then the first set to which the channel resources of the channel belong is SRS resource set associated with the channel resource group to which the channel resources of the channel belong, or the first set to which the resource set of the signal belongs is SRS resource set associated with the resource set of the signal. That is, the TRP to which the channel resource of the channel belongs is the TRP indicated by the SRS resource set associated with the channel resource group to which the channel resource of the channel belongs, or the TRP to which the resource set of the signal belongs is the TRP indicated by the SRS resource set associated with the resource set of the signal.

Alternatively, the association relationship between each channel resource group or each resource set and each SRS resource set may be predefined, for example, channel resource group 1 or resource set1 is associated with SRS resource set1, and channel resource group 2 or resource set2 is associated with SRS resource set 2. Alternatively, the association relationship between each channel resource group or each resource set and each SRS resource set is configured in advance, for example, channel resource group 1 or resource set1 is associated with SRS resource set2, and channel resource group 2 or resource set2 is associated with SRS resource set 1.

In yet another alternative embodiment, if the first set is a set of beam failure detection reference signal resources as in embodiment 3.3, i.e. different sets of beam failure detection reference signal resources represent different TRPs, then the first set of channel resources of the channel is a set of beam failure detection reference signal resources associated with a channel resource group to which the channel resources of the channel belong, or the first set of signal resources is a set of beam failure detection reference signal resources associated with a resource set of the signal. That is, the TRP to which the channel resource of the channel belongs is the TRP indicated by the beam failure detection reference signal resource set associated with the channel resource group to which the channel resource of the channel belongs, or the TRP to which the resource set of the signal belongs is the TRP indicated by the beam failure detection reference signal resource set associated with the resource set of the signal.

Alternatively, the association between each channel resource group or each resource set and each beam failure detection reference signal resource set may be predefined, for example, channel resource group 1 or resource set 1 is associated with beam failure detection reference signal resource set 1, and channel resource group 2 or resource set 2 is associated with beam failure detection reference signal resource set 2. Alternatively, the association relationship between each channel resource group or each resource set and each beam failure detection reference signal resource set is configured in advance, for example, the channel resource group 1 or the resource set 1 is associated with the beam failure detection reference signal resource set 2, and the channel resource group 2 or the resource set 2 is associated with the beam failure detection reference signal resource set 1.

In yet another alternative embodiment, if the first set is a PUCCH resource set as in embodiment 3.4, i.e. different PUCCH resource sets represent different TRPs, then the first set to which the channel resources of the channel belong is a PUCCH resource set associated with a channel resource group to which the channel resources of the channel belong, or the first set to which the resource set of the signal belongs is a PUCCH resource set associated with the resource set of the signal. That is, the TRP to which the channel resource of the channel belongs is the TRP represented by the PUCCH resource set associated with the channel resource group to which the channel resource of the channel belongs, or the TRP to which the resource set of the signal belongs is the TRP represented by the PUCCH resource set associated with the resource set of the signal. Wherein, the PUCCH resource set may include one or more PUCCH resources, each PUCCH resource may have one or more time domain units (e.g. symbols or slots, etc.), and one or more frequency domain units (e.g. subcarriers or resource blocks, etc.).

Alternatively, the association between each channel resource group or each resource set and each PUCCH resource set may be predefined, e.g. channel resource group 1 or resource set 1 is associated with PUCCH resource set 1, and channel resource group 2 or resource set 2 is associated with PUCCH resource set 2. Alternatively, the association relationship between each channel resource group or each resource set and each PUCCH resource set is configured in advance, for example, channel resource group 1 or resource set 1 is associated with PUCCH resource set 2, and channel resource group 2 or resource set 2 is associated with PUCCH resource set 1.

Embodiment 1.3. The first information is a set of channel sounding reference signal (Sounding reference signal, SRS) resources for a channel association;

optionally, the channel is PUSCH. The PUSCH has an association relationship with the SRS resource set, and the SRS resource set associated with the PUSCH indicates or belongs to which TRP, and the PUSCH belongs to which TRP.

In an alternative embodiment, if the first set is a CORESET set as in embodiment 3.1, i.e. different CORESET groups represent different TRPs, then the first set to which PUSCH resources belong is a CORESET set associated with a PUSCH-associated SRS resource set. That is, the TRP to which the PUSCH resource belongs is the TRP indicated by the CORESET group associated with the SRS resource set associated with the PUSCH.

Alternatively, the association between each SRS resource set and each CORESET group may be predefined, such as SRS resource set 1 being associated with CORESET 1 and SRS resource set 2 being associated with CORESET 2. Alternatively, the association relationship between each SRS resource set and each CORESET group is configured in advance, for example, SRS resource set 1 is associated with CORESET 2, and SRS resource set 2 is associated with CORESET 1.

In another alternative embodiment, if the first set is SRS resource set as in embodiment 3.2, that is, different SRS resource sets represent different TRPs, then the first set to which PUSCH resources belong is a PUSCH-associated SRS resource set. That is, the TRP to which the PUSCH resource belongs is the TRP indicated by the SRS resource set associated with the PUSCH. Wherein, the TRP to which the PUSCH resource belongs indicates that the TRP receives the PUSCH on the PUSCH resource.

Optionally, the SRS resource set associated with the PUSCH is determined according to the value of the SRS resource set indication (SRS resource set indicator) field. That is, the terminal device may determine the association relationship between the PUSCH and the SRS resource set based on the value of the SRS resource set indicator field.

In yet another alternative embodiment, if the first set is a set of beam failure detection reference signal resources as in embodiment 3.3, i.e. different sets of beam failure detection reference signal resources represent different TRPs, then the first set to which the channel resources of the channel belong is a set of beam failure detection reference signal resources associated with a set of PUSCH-associated SRS resources. That is, the TRP to which the channel resource of the channel belongs is the TRP indicated by the beam failure detection reference signal resource set associated with the SRS resource set associated with the PUSCH.

Alternatively, the association relationship between each SRS resource set and each beam failure detection reference signal resource set may be predefined, for example, SRS resource set 1 is associated with beam failure detection reference signal resource set 1, and SRS resource set 2 is associated with beam failure detection reference signal resource set 2. Alternatively, the association relationship between each SRS resource set and each beam failure detection reference signal resource set is configured in advance, for example, SRS resource set 1 is associated with beam failure detection reference signal resource set 2, and SRS resource set 2 is associated with beam failure detection reference signal resource set 1.

In yet another alternative embodiment, if the first set is a PUCCH resource set as in embodiment 3.4, i.e. different PUCCH resource sets represent different TRPs, then the first set to which PUSCH resources belong is a PUCCH resource set associated with a PUSCH-associated SRS resource set. That is, the TRP to which the PUSCH resource belongs is the TRP indicated by the PUCCH resource set associated with the SRS resource set associated with the PUSCH.

Alternatively, the association relationship between each SRS resource set and each PUCCH resource set may be predefined, for example, SRS resource set 1 is associated with PUCCH resource set 1, and SRS resource set 2 is associated with PUCCH resource set 2. Alternatively, the association relationship between each SRS resource set and each PUCCH resource set is configured in advance, for example, SRS resource set 1 is associated with PUCCH resource set 2, and SRS resource set 2 is associated with PUCCH resource set 1.

That is, regardless of whether the first set is any of embodiments 3.1 to 3.4 described above, the second parameter configuration of a channel or signal may directly configure the first set to which the channel resource or resource set of the channel belongs. The network device may send a second parameter configuration of the channel or signal, and the terminal device receives the second parameter configuration of the channel or signal and learns, based on the second parameter configuration, a first set to which the channel or signal belongs. The network device configured to send the second parameter of the channel or the signal to the terminal device may be one of the network devices of the plurality of cooperative transmission, or may be the network device of the plurality of cooperative transmission.

As described above, the first set includes, but is not limited to, what is described in the foregoing embodiments 3.1 to 3.4, and may also be a new element, such as an index of TRP, and correspondingly, the foregoing embodiments 1.1 to 1.4 may respectively learn the TRP to which the channel or signal belongs in combination with the index of the first set as the TRP. And will not be described in detail herein.

Referring to fig. 3, fig. 3 is a flowchart illustrating a communication method 200 according to an embodiment of the application. As shown in fig. 3, the communication method 200 may include, but is not limited to, the following steps:

s201, network equipment sends DCI or MAC information; correspondingly, the terminal device receives the DCI or MAC information.

Wherein the DCI includes a transmission configuration indication, TCI, field to indicate one or more TCI states, or to indicate one or more pairs of TCI states; the MAC information is used to configure one or more TCI states, or to configure one or more pairs of TCI states.

The MAC information may be a medium access control element (MAC CE).

Each TCI state is for uplink and downlink; alternatively, one TCI state of each pair of TCI states is used for uplink and the other TCI state is used for downlink. Alternatively, the terminal device may determine each TCI state or each pair of TCI states for uplink and/or downlink based on whether the JointULDL mechanism or the SeparateULDL mechanism is configured, see in particular the foregoing, which is not described in detail herein.

S202, the terminal equipment determines a first set to which each or each pair of TCI states belong according to DCI or MAC information.

Embodiment 2.1. The terminal device determines, according to DCI or MAC information, a first set to which each or each pair of TCI states belongs, including: determining a first set to which each TCI state belongs according to the position or the identification of the TCI state indicated by the TCI field; or determining a first set to which each TCI state belongs according to the position or the identification of the TCI state configured by the MAC information; or determining a first set to which each pair of TCI states belongs according to the position or the identification of each pair of TCI states indicated by the TCI field; or determining the first set to which each pair of TCI states belongs according to the position or the identification of each pair of TCI states configured by the MAC information.

For example, for the JointULDL mechanism, if the TCI field indicates two TCI states, position 1, position 2, respectively, of the TCI field, then the TCI state of position 1 belongs to or is associated with a first set and the TCI state of position 2 belongs to or is associated with a second first set. For another example, for the JointULDL mechanism, if the TCI field indicates two TCI states, corresponding to ID 1, ID 2, respectively, then the TCI state of ID 1 belongs to or is associated with the first set and the TCI state of ID 2 belongs to or is associated with the second first set.

For another example, for the JointULDL mechanism, if two TCI states configured by the MAC information are located at positions 1, 2, respectively, in the MAC information, then the TCI state at position 1 belongs to or is associated with the first set and the TCI state at position 2 belongs to or is associated with the second first set. For another example, for the JointULDL mechanism, if two TCI states of the MAC information configuration correspond to identity 1, identity 2, respectively, then the TCI state of identity 1 belongs to or is associated with a first set and the TCI state of identity 2 belongs to or is associated with a second first set.

For another example, for the SeparateULDL mechanism, if the TCI field indicates two pairs of TCI states, at positions 1, 2 of the TCI field, respectively, then the pair of TCI states at position 1 belongs to or is associated with the first set and the pair of TCI states at position 2 belongs to or is associated with the second first set. For another example, for the separaduldl mechanism, if the TCI field indicates two pairs of TCI states, corresponding to identity 1, identity 2, respectively, then the pair of TCI states of identity 1 belongs to or is associated with a first set and the pair of TCI states of identity 2 belongs to or is associated with a second first set.

For another example, for the separaduldl mechanism, if two pairs of TCI states configured by the MAC information are located at positions 1 and 2 in the MAC information, respectively, then the pair of TCI states at position 1 belongs to or is associated with the first set and the pair of TCI states at position 2 belongs to or is associated with the second first set. For another example, for the separaduldl mechanism, if two pairs of TCI states configured by MAC information correspond to identifier 1, identifier 2, respectively, then the pair of TCI states of identifier 1 belongs to or is associated with the first set and the pair of TCI states of identifier 2 belongs to or is associated with the second first set.

It should be noted that, the above-mentioned position 1, position 2, or the marks 1, 2 may also be expressed in other manners, for example, the position 1 may be expressed as a first position, the position 2 may be expressed as a second position, etc., which is not limited in this embodiment of the present application.

In an alternative embodiment, for the JointULDL mechanism, if the TCI field indicates a TCI state, the terminal may understand a single TRP scenario and may determine which TRP is the one to which the TCI state belongs or is associated with based on the location or identity of the TCI state in the TCI state indicated by the TCI field.

For example, if the TCI field indicates one TCI state and is the TCI state of location 2, the terminal may understand a single TRP scenario and may determine that the TCI state of location 2 belongs to or is associated with a second first set, such as TRP2.

In an alternative embodiment, the JointULDL mechanism, if the MAC information configures a TCI state, the terminal may understand a single TRP scenario and may determine which TRP is the one to which the TCI state belongs or is associated with based on the location or identity of the TCI state in the TCI state indicated by the TCI field.

For example, if the MAC information is assigned a TCI state and is a TCI state of location 2, the terminal may understand a single TRP scenario and may determine that the TCI state of location 2 belongs to or is associated with a second first set, such as TRP2.

In an alternative embodiment, for the separauldl mechanism, if the TCI field indicates a pair of TCI states, the terminal may be understood as a single TRP scenario, and may determine which TRP is the one to which the pair of TCI states belongs or is associated based on the location or identity of the pair of TCI states in the TCI state indicated by the TCI field.

For example, if the TCI field indicates a pair of TCI states and is a pair of TCI states for location 2, the terminal may understand a single TRP scenario and may determine that the pair of TCI states for that location 2 belongs to or is associated with a second first set, such as TRP2.

In an alternative embodiment, the separauldl mechanism, if the MAC information configures a pair of TCI states, the terminal may understand a single TRP scenario and may determine which TRP is the one to which the pair of TCI states belongs or is associated with based on the location or identity of the pair of TCI states in the TCI states indicated by the TCI field.

For example, if the MAC information is assigned a pair of TCI states and is the TCI state of location 2, the terminal may understand a single TRP scenario and may determine that the pair of TCI states of location 2 belongs to or is associated with a second first set, such as TRP2.

Embodiment 2.2. The terminal device determines, from the DCI, a first set to which each or each pair of TCI states belongs, including: determining CORESET associated with PDCCH carrying DCI; based on the determined CORESET, a first set to which each or each pair of TCI states belongs is determined.

Wherein, as described above, the core associated with the PDCCH is the core configured by the search space containing the PDCCH. For example, the CORESET of search space configurations including the first PDCCH includes the first CORESET, and then the CORESET associated with the first PDCCH is the first CORESET.

Wherein, for the JointULDL mechanism, DCI is used to indicate 1 TCI state, or MAC information is used to configure 1 TCI state. Alternatively, if the DCI indicates 2 TCI states under the JointULDL mechanism, the terminal device may consider the TCI state indicated by the DCI invalid.

For the separauldl mechanism, one DCI may indicate one pair or 2 pairs of TCI states. Alternatively, if the DCI indicates 2 pairs of TCI states, then the TCI state indicated by this DCI is considered invalid.

In the embodiment of the present application, the first set includes, but is not limited to, those described in embodiments 3.1 to 3.4, where the first set is a CORESET, or an SRS resource set, or a beam failure detection reference signal resource set, or a PUCCH resource set.

For example, where the first set is a CORESET group, the CORESET group to which the TCI state belongs may be the CORESET group to which the CORESET associated with the PDCCH carrying the DCI belongs. Or, the CORESET group to which the first TCI state belongs in the TCI state indicated by the TCI field or the MAC information is CORESET group 1, and the CORESET group to which the second TCI state belongs is CORESET group 2. Or the CORESET group to which the TCI state of the minimum ID in the TCI state indicated by the TCI field or the MAC information belongs is CORESET group 1, and the CORESET group to which the TCI state of the larger ID belongs is CORESET group 2.

For another example, the first set is an SRS resource set, and the SRS resource set to which the TCI state belongs may be a CORESET-associated SRS resource set associated with a PDCCH carrying DCI. Or, the SRS resource set to which the first TCI state belongs in the TCI state indicated by the TCI field or the MAC information is the SRS resource set 1, and the SRS resource set to which the second TCI state belongs is the SRS resource set 2. Or, the SRS resource set to which the TCI state of the minimum ID in the TCI state indicated by the TCI field or the MAC information belongs is the SRS resource set 1, and the SRS resource set to which the TCI state of the larger ID belongs is the SRS resource set 2.

For another example, the first set is a beam failure detection reference signal resource set, and the beam failure detection reference signal resource set to which the TCI state belongs may be a beam failure detection reference signal resource set associated with CORESET associated with PDCCH carrying DCI. Or, the beam failure detection reference signal resource set to which the first TCI state belongs in the TCI state indicated by the TCI field or the MAC information is the beam failure detection reference signal resource set 1, and the beam failure detection reference signal resource set to which the second TCI state belongs is the beam failure detection reference signal resource set 2. Or, the beam failure detection reference signal resource set to which the TCI state of the minimum ID in the TCI state indicated by the TCI field or the MAC information belongs is the beam failure detection reference signal resource set 1, and the beam failure detection reference signal resource set to which the TCI state of the larger ID belongs is the beam failure detection reference signal resource set 2.

For another example, in the case where the first set is a PUCCH resource set, the PUCCH resource set to which the TCI state belongs may be a CORESET-associated PUCCH resource set associated with a PDCCH carrying DCI. Or, the PUCCH resource set to which the first TCI state belongs in the TCI state indicated by the TCI field or the MAC information is PUCCH resource set 1, and the PUCCH resource set to which the second TCI state belongs is PUCCH resource set 2. Or, the PUCCH resource set to which the TCI state of the minimum ID in the TCI state indicated by the TCI field or the MAC information belongs is PUCCH resource set 1, and the PUCCH resource set to which the TCI state of the larger ID belongs is PUCCH resource set 2.

For another example, the first set is TRP, and the TRP to which the TCI state belongs may be TRP to which CORESET associated with the PDCCH carrying the DCI belongs. Alternatively, the TRP to which the first TCI state belongs in the TCI state indicated by the TCI field or the MAC information is TRP1, and the TRP to which the second TCI state belongs is TRP2. Alternatively, the TRP to which the TCI state of the minimum ID in the TCI field indicated or the MAC information belongs is TRP1, and the TRP to which the TCI state of the larger ID belongs is TRP2.
