[0042] For example, the communication system 100 used in the embodiment of the present application is as follows: Figure 1 The communication system 100 may include a network device 110, which may be a device that communicates with a terminal device 120 (or a communication terminal or terminal).

Optionally, the communication system 100 may include multiple network devices and each network device may include another number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0044] Optionally, the communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiments of the present application.

[0045] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be referred to as a communication device. Figure 1Taking the communication system 100 shown as an example, the communication equipment may include a network device 110 and a terminal device 120 with communication functions. The network device 110 and the terminal device 120 may be the specific devices described above and will not be repeated here. The communication equipment may also include other devices in the communication system 100, such as a network controller, a mobile management entity and other network entities, which is not limited in the embodiments of the present application.

[0046] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0047] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0048] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0049] In the embodiments of the present application, "pre-definition" can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device), and the present application does not limit the specific implementation method. For example, pre-definition can refer to what is defined in the protocol.

[0050] In the embodiments of the present application, the "protocol" may refer to a standard protocol in the communication field, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and the present application does not limit this.

[0051] To facilitate understanding of the technical solutions of the embodiments of the present application, the timing advance (TA) related to the present application is explained.

[0052] In some scenarios, in a cell group (CG), the UE can be configured with up to 4 timing advance groups (TAGs). TAG can be configured through Radio Resource Control (RRC). Optionally, a CG can include multiple serving cells, and each serving cell will be assigned a TAG identifier (Timing Advance Group Identity, TAG-Id). Each TAG will have a time alignment timer (TimeAlignmentTimer), and the UE will count the time alignment timer. When this timer times out, the UE will consider that the TAG is out of uplink synchronization. When the network device adjusts the TA value through the Media Access Control Control Element (MAC CE) or other signaling during the operation of the timer, the timer will be reset, and the UE will consider that the TAG is in uplink synchronization state. For example, if the value of TimeAlignmentTimer is configured to 500ms, that is, the network device needs to update (adjust) the TA value of the UE once within 500ms, otherwise, the UE may consider that the uplink is out of synchronization and may initiate a random access process when uplink data arrives.

[0053] In some scenarios, the TA of the UE can be calculated according to the following formula. The TA of the UE is based on the first path of the downlink channel received by the UE, that is, the first symbol of the time slot where the channel is located as the downlink reference, and the early transmission is performed on this basis:

[0054] (N TA +N TA,offset )*T C

[0055] In a CG, each serving cell can be pre-configured with a timing advance offset (TA offset), for example, through a high-level parameter (n-TimingAdvanceOffset), that is, N in the formula TA,offset . Among them, TA adjustment amount (N TA ) is based on the pre-configured TAoffset. C is the minimum time unit in the NR system, T C =1 / (4096*480kHz). N TA The MAC CE of the network device can provide differential adjustment, that is, the current TA adjustment (new) is adjusted forward or backward in time based on the previous TA (old). The calculation formula is as follows:

[0056]

[0057] The MAC CE format for differential adjustment of TA is as follows: Figure 2 As shown in the figure, the adjustment of TA is to adjust T based on the last TA. A The minimum time unit is TAG, and the granularity of TA adjustment is TAG.

[0058] In other scenarios, the network device may indicate to the UE the absolute value of the TA for uplink transmission. For example, the network device may indicate to the UE the absolute value of the TA for uplink transmission. Figure 3 The MAC CE command shown directly indicates the absolute value of TA N TA , its value range is 0 to 3846, and its length is 12 bits. According to the formula N TA =T A *16*64*2 μ The indication range of the TA can be determined. And the MAC CE command is applicable to the Primary Timing Advance Group (PTAG) corresponding to the corresponding MAC entity, that is, the definition of the PTAG includes a special cell (SpCell). Because the MAC CE is only applicable to PTAG, it does not need to include TAG-Id.

[0059] In some scenarios, during the initial access (cell) of the UE, after the UE sends a Physical Random Access Channel (PRACH) to the network device, the UE expects the network device to give the UE a TA indication through a Media Access Control Random Access Response (MAC RAR) within a certain time window. Figure 4 The figure shows a format of MAC RAR signaling carrying TA. The UE can obtain an initial TA absolute value of 12 bits based on the MAC RAR.

[0060] If the UE operates in single TRP (sTRP) mode, the reference point of the UE timing advance is calculated from the downlink reception time point and is advanced forward (N TA +N TA,offset )*T C The time to send the uplink channel or uplink signal, such as Figure 5 shown.

[0061] In some scenarios, support for repetition of Physical Uplink Control Channel (PUCCH) or Physical Uplink Shared Channel (PUSCH) based on multi-TRP (mTRP) is provided to enhance uplink coverage and transmission reliability. The UE needs to send PUCCH or PUSCH carrying the same content to different TRPs. For repeated transmission of multiple PUSCH (multi-PUSCH) based on single downlink control information (DCI, sDCI), the UE can use one TA to sequentially send PUSCH to different TRPs; for repeated transmission of multi-PUSCH based on multiple DCI (multi-DCI, mDCI), since there may not be a sufficiently ideal backhaul as a connection between multiple TRPs, multiple TRPs independently schedule the UE. This operation may cause temporal overlap of PUSCH / PUCCH for different TRPs. Therefore, it is also necessary to support different TA updates or indications for different TRPs.

[0062] In some scenarios, consider supporting the mechanism of multiple antenna panels of UE to transmit PUCCH / PUSCH to multiple TRPs at the same time. But similarly, even with the configuration of multiple uplink transmit antenna panels and multiple TRP reception, UE can only use one TA for early transmission in a serving cell. Such a limitation should obviously be broken, that is, to support TRP-specific TA acquisition and indication.

[0063] For example, in the scenario of mDCI-mTRP within a cell, TRP#1 and TRP#2 use the same PCI, such as Figure 6 As shown. Each TRP can schedule PDSCH / PUSCH transmission on the TRP through its own DCI. It is worth noting that in the operation of mDCI-mTRP, the control resource set (CORESET) is grouped by the RRC parameter control resource set pool index (CORESETPoolIndex). For example, the CORESET with CORESETPoolIndex of "0" is divided into a group, corresponding to one TRP; the CORESET with CORESETPoolIndex of "1" is divided into another group, corresponding to another TRP. When the network device does not configure CORESETPoolIndex for the CORESET, its default value is "0".

[0064] In the inter-cell mDCI-mTRP scenario, Figure 6 TRP#1 in the figure can be understood as the reference TRP, that is, the TRP accessed by the UE when it initially accesses. The UE has achieved uplink and downlink synchronization, and it has an exclusive physical cell identifier (PCI) #1. As for other TRPs, since the network equipment can select one TRP from up to 7 TRPs to provide additional uplink transmission services for the UE, these TRPs have different PCIs from the service TRP, and often no uplink and downlink synchronization is established with the UE in advance.

[0065] In some scenarios, it is considered to support a mTRP PUSCH transmission scheme based on a single DCI (Single-DCI, S-DCI), such as a single frequency network (SFN) scheme or a space division multiplexing (SDM) scheme.

[0066] For the SFN solution, it can mean that the network device sends uplink scheduling information from one TRP, and the scheduled UE sends the same PUSCH to multiple TRPs on the same time-frequency resources. The network device can decode the PUSCH received from multiple TRPs independently or after merging them. The latter can obtain a lower PUSCH error probability, that is, a lower block error rate (BLER), compared with independent decoding.

[0067] For the SDM solution, it can mean that the network device sends uplink scheduling information from one TRP, and the scheduled UE sends different PUSCHs to multiple TRPs on the same or repeated time domain resources. For example, the UE sends PUSCH#1 of Rank 1 to TRP#1, and PUSCH#2 of Rank 2 to TRP#2. The benefit of this is that the uplink throughput can be increased.

[0068] In some scenarios, the concept of Transmission Configuration Indicator (TCI) state is proposed, which is used for downlink spatial domain quasi-co-located (QCL) (beam) indication and the transmission of QCL information in the time and frequency domains. Specifically, the quasi-co-located (QCL) relationship can be simply described as a large-scale fading relationship from a source reference signal to a target reference signal. For beam indication, after the UE obtains the QCL relationship between the two source reference signals and the target reference signal from the network device, it can use the receiving beam that previously received the source reference signal when receiving the target reference signal.

[0069] In some scenarios, the TCI state indication mechanism is only applicable to downlink channels and signals. For uplink beam indication, the concept of spatial relation is defined to express the spatial relationship between two reference signals.

[0070] In some scenarios, in order to provide a unified uplink and downlink beam management mechanism for the communication system, the concept of unified TCI state is proposed based on the design of TCIstate. The important functions it adds are as follows:

[0071] 1. Three unified TCI state modes are designed. The joint TCI state is applicable to uplink and downlink channels and signals; the downlink (DL) TCI state is only applicable to downlink channels and signals; and the uplink (DL) TCI state is only applicable to uplink channels and signals.

[0072] 2. Downlink channels (part of the Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH)) and signals (aperiodic Channel State Information Reference Signal (CSI-RS)) use the same downlink transmit beam, for example, using DL TCI state or joint TCI state.

[0073] 3. Uplink channels (eg, PUCCH, PUSCH) and signals (eg, Sounding Reference Signal (SRS)) use the same uplink transmit beam, using UL TCI state or joint TCI state.

[0074] 4. Unified TCI state can be dynamically updated and indicated using MAC CE and / or DCI.

[0075] 5. Applicable to the scenario of carrier aggregation, the beam indication on a single component carrier (CC) can be applicable to multiple different CCs.

[0076] 6. The uplink beam indication can be given simultaneously with the uplink power control parameters through UL TCI state or joint TCIstate.

[0077] 7. Support beam management function between cells.

[0078] In some scenarios, a serving cell (including single-TRP and multi-TRP scenarios) has only one TAG and a corresponding TA timer. When the TA timer times out, the UE needs to release all reserved uplink and downlink resources on the serving cell. When the serving cell is configured with multiple TAGs, how to release resources is an urgent problem to be solved.

[0079] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0080] Figure 7 is a schematic interaction diagram of a wireless communication method 200 according to an embodiment of the present application, such as Figure 7 As shown, the method 200 includes at least part of the following:

[0081] S210, when the timer corresponding to the first timing advance group TAG times out, the terminal device releases the resources associated with the first parameter, where the first parameter is associated with the first TAG.

[0082] In some embodiments, the first parameter may include, but is not limited to, at least one of the following parameters:

[0083] The first TCI state, the first spatial relation information, the first control resource set pool index (CORESETPoolIndex), and the first uplink RRC parameter.

[0084] In some embodiments, the first parameter is associated with a first network node, such as a first TRP.

[0085] In some embodiments, a network device (eg, a base station) may correspond to multiple network nodes. For example, uplink transmissions associated with different first parameters may be considered to be received by different network nodes. For another example, downlink transmissions associated with different first parameters may be considered to be sent from different network nodes.

[0086] In some embodiments, the timer corresponding to the first TAG may be a TimeAlignmentTimer. When the timer corresponding to the first TAG times out, the terminal device considers that the first TAG is out of uplink synchronization, or in other words, the terminal device is out of uplink synchronization with the first network node.

[0087] In some embodiments, the service cell of the terminal device is associated with at least two TAGs, the first TAG is one of the at least two TAGs, each TAG corresponds to a TAG ID, for example, the first TAG corresponds to the first TAG ID, the timer corresponding to the first TAG may refer to the timer corresponding to the first TAG ID, and the association between the first parameter and the first TAG may refer to the association between the first TAG ID and the first parameter.

[0088] In some embodiments, the first TAG is a PTAG among the at least two TAGs.

[0089] In some embodiments of the present application, S210 includes:

[0090] When the timer corresponding to the first TAG times out and the timers corresponding to other TAGs among the at least two TAGs except the first TAG have not timed out, the terminal device only releases the resources associated with the first parameter associated with the first TAG.

[0091] That is, when only the timer corresponding to the first TAG times out, and the timers corresponding to other TAGs do not time out, it indicates that the terminal device has an uplink desynchronization with the first network node, and has not experienced an uplink desynchronization with other network nodes. Therefore, the terminal device can release uplink and downlink resources only for the first network node, without releasing all reserved uplink and downlink resources on the service cell of the terminal device. For example, the resources are released according to the first parameter associated with the first TAG, for example, the resources associated with the first parameter are released.

[0092] In some embodiments, the association relationship between the first TAG and the first parameter may be predefined, configured by the network device, or determined according to a preset rule.

[0093] For example, Figure 7 As shown, the method also includes:

[0094] S201, the network device may send first configuration information to the terminal device, the first configuration information is used to configure a first association relationship, the first association relationship is an association relationship between the TAG and at least one of the following parameters: TCI state, spatial relationship information, CORESETPoolIndex, uplink RRC parameter. The first association relationship includes an association relationship between a first TCI state and a first parameter.

[0095] In some embodiments, the first configuration information is sent via at least one of the following signaling:

[0096] System messages, RRC signaling, media access control MAC control element CE, downlink control information DCI.

[0097] For example, a first TAGID may be added to an information element (IE) of the first parameter to establish an association relationship between the first TAG and the first parameter.

[0098] The following describes the method of releasing the first parameter and the associated resources in conjunction with a specific embodiment.

[0099] Embodiment 1: The first parameter is a first TCI state.

[0100] Embodiment 1-1: The first TCI state includes a first uplink TCI state (UL TCI state) or a first joint TCI state (joint TCI state).

[0101] In some embodiments, when the timer corresponding to the first TAG times out, the terminal device can determine the associated UL / joint TCI state according to the first TAG, and further the uplink resources associated with the UL / joint TCI state. The advantage of using the UL / joint TCI state and TAG association is that, compared with the scheme in which TAG is associated with CORESETPoolIndex, the TAG can use the downlink reference signal contained in the UL / joint TCI state as a downlink synchronization time reference, that is, the terminal device can determine the transmission time of the physical random access channel (Physical Random Access Channel, PRACH) based on the reception time of the downlink reference signal. In addition, in the millimeter wave frequency band, the UL / joint TCI state can provide beam-level downlink and uplink synchronization, which is more accurate than the synchronization at the network node level (in which a network node uses multiple beams for coverage, and multiple beams experience different path transmission delays).

[0102] Embodiment 1-1-1: Release the PUCCH resources or PUCCH resource group applying the first uplink TCI state (UL TCI state) or the first joint TCI state (joint TCI state).

[0103] In this embodiment 1-1-1, the first uplink TCI state or the first joint TCI state can be used to indicate the reference signal (or beam) corresponding to the uplink channel to which it is applied.

[0104] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated uplink TCI state or joint TCI state according to the first TAG, and further release the PUCCH resources or PUCCH resource group to which the uplink TCI state or joint TCI state is applied.

[0105] In some embodiments, the PUCCH resource or PUCCH resource group to which the first TCI state is applied is a first PUCCH resource or a first PUCCH resource group, and when the timer corresponding to the first TAG times out, the first PUCCH resource or the first PUCCH resource group can be released. That is, the resources associated with the first parameter include the first PUCCH resource or the first PUCCH resource group.

[0106] In some embodiments, the network device may configure (or indicate, activate) an uplink TCI state or a joint TCI state for a PUCCH resource or a PUCCH resource group. In this case, it can be considered that the uplink TCI state or the joint TCI state can be applied to the PUCCH resource or the PUCCH resource group. For example, the network device may configure a TCI state resource pool through RRC signaling, for example, including 128 UL / joint TCI states, further activate 8 TCI states or a combination of TCIstates (including two joint / UL TCI states) through MAC CE, and finally indicate the target TCI state in the TCI state activated by MAC CE through the TCI state indication field (such as 3 bits) in DCI (such as DCI format 1_1 / 1_2). The UL / joint TCI state indicated by the DCI is applicable to all PUCCH resources / resource groups and PUSCH resources configured by the network device.

[0107] In some embodiments, the network device may configure (or indicate, activate) an uplink TCI state or a joint TCI state for a PUCCH resource or a PUCCH resource group (recorded as case 1), or may configure (or indicate, activate) multiple uplink TCI states or joint TCI states for a PUCCH resource or a PUCCH resource group (recorded as case 2), such as two uplink TCI states or two joint TCI states, or a combination of an uplink TCI state and a joint TCI state, in which case the terminal device transmits PUCCH to multiple network nodes. Optionally, the PUCCH transmission of the terminal device to multiple network nodes may adopt a time-division multiplexing (TDM) scheme (such as repeated transmission of PUCCH sent to different network nodes on different time domain resources), or may adopt an SFN scheme or an SDM scheme.

[0108] For case 1, when the timer corresponding to the first TAG times out, the terminal device can determine the associated uplink TCI state or joint TCI state based on the first TAG, and further release the PUCCH resources or PUCCH resource group to which the uplink TCI state or joint TCI state is applied.

[0109] For case 2: when the timer corresponding to the first TAG times out, as an implementation method, the first PUCCH resource or the first PUCCH resource group is released because the terminal device has experienced uplink desynchronization with the first network node, and the repeated transmission of the PUCCH cannot be completed, so the first PUCCH resource or the first PUCCH resource group can be released. As another implementation method, the first PUCCH resource or the first PUCCH resource group is not released because the terminal device has experienced uplink desynchronization with the first network node. When the terminal device does not experience uplink desynchronization with other network nodes, it can continue to send PUCCH to other network devices.

[0110] For example, when the first TAG is associated with the first UL / joint TCI state, and the network device configures only the first UL / joint TCI state for the first PUCCH resource or the first PUCCH resource group, it can be considered that the first PUCCH resource or the first PUCCH resource group only corresponds to the first UL / joint TCI state, that is, the first PUCCH resource or the first PUCCH resource group only uses the first UL / joint TCI state. In this case, when the timer corresponding to the first TAG times out, the terminal device can release the PUCCH resource or PUCCH resource group to which the first UL / joint TCI state is applied, that is, the first PUCCH resource or the first PUCCH resource group. Alternatively, if the network device configures the first UL / joint TCI state and the second UL / joint TCI state for the first PUCCH resource or the first PUCCH resource group, it can be considered that the first PUCCH resource or the first PUCCH resource group corresponds to the first UL / joint TCI state and the second UL / joint TCI state, that is, the first PUCCH resource or the first PUCCH resource group uses the first UL / joint TCI state and the second UL / joint TCI state. In this case, when the timer corresponding to the first TAG expires, the terminal device can release the PUCCH resources or PUCCH resource group applying the first UL / joint TCI state, that is, the first PUCCH resources or the first PUCCH resource group.

[0111] Embodiment 1-1-2: Release the SRS resources or SRS resource set associated with the first uplink TCI state (UL TCI state) or the first joint TCI state (jointTCI state). For example, when the timer corresponding to the first TAG expires, the terminal device can determine the associated uplink TCI state or joint TCI state according to the first TAG, and further release the SRS resources or SRS resource set associated with the uplink TCI state or joint TCI state.

[0112] In some embodiments, the first UL / joint TCI state is used to indicate an uplink signal, and the first SRS resource or the first SRS resource set can be configured with the first UL / joint TCI state. When the timer associated with the first TAG expires, the first SRS resource or the first SRS resource set associated with the first UL / joint TCI state associated with the first TAG can be released, and the first SRS resource or the first SRS resource set is used to track the uplink signal indicated by the first UL / joint TCI state.

[0113] That is, the resources associated with the first parameter include a sounding reference signal SRS resource or an SRS resource set associated with the first TCI state, and the SRS resource or the SRS resource set is configured to track the uplink signal indicated by the first TCI state.

[0114] In some embodiments, when the first SRS resource or the first SRS resource set is not configured with UL / joint TCIstate, that is, the first SRS resource or the first SRS resource set is not configured to follow the uplink signal, then when the timer corresponding to the first TAG expires, the terminal device may choose to release the first SRS resource or the first SRS resource set, or may not release the first SRS resource or the first SRS resource set.

[0115] Embodiment 1-1-3: Release the pre-configured PUSCH resources applying the first uplink TCI state (UL TCI state) or the first joint TCI state (joint TCI state).

[0116] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated uplink TCI state or joint TCI state according to the first TAG, and further release the pre-configured PUSCH resources associated with the uplink TCI state or joint TCI state.

[0117] That is, the resources associated with the first parameter include pre-configured PUSCH resources to which the first TCI state is applied.

[0118] In some embodiments, PUSCH resources may be dynamically scheduled, or may be semi-statically configured (or pre-configured).

[0119] For dynamically scheduled PUSCH resources, when a terminal device enters an uplink out-of-sync state with respect to a network node, the network device may avoid scheduling the terminal device to perform uplink transmission to the network node.

[0120] For preconfigured PUSCH resources, the network device can configure (or indicate, activate) one or more UL / joint TCI states (for example, configure the first TCI state, the second TCI state, or the first TCI state and the second TCI state) for the PUSCH resources. Then, when the timer corresponding to the first TAG expires, the terminal device can determine the UL / jointTCI state associated with the first TAG, and further release the preconfigured PUSCH resources to which the UL / joint TCI state is applied.

[0121] Optionally, the pre-configured PUSCH resources include PUSCH resources carrying configured uplink grants (configured UL grants) and / or PUSCH resources for semi-persistent channel state information CSI reporting (PUSCH for semi-persistent CSI reporting).

[0122] It should be understood that the above-mentioned Embodiment 1-1-1, Embodiment 1-1-2 and Embodiment 1-1-3 may be implemented individually or in combination.

[0123] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated UL / joint TCI state based on the first TAG, and further release at least two of the PUCCH resources applying the UL / joint TCI state, the associated SRS resources or SRS resource group of the UL / joint TCI state, and the pre-configured PUSCH resources applying the UL / joint TCI state.

[0124] Optionally, in this embodiment 1-1, the uplink resources associated with the first UL / joint TCI state may include at least one of the following:

[0125] PUCCH resources or PUCCH resource groups applying the first UL / joint TCI state;

[0126] The SRS resource or SRS resource group associated with the first UL / joint TCI state;

[0127] The pre-configured PUSCH resources of the first UL / joint TCI state are applied.

[0128] Embodiment 1-2: The first TCI state includes a first downlink TCI state or a first joint TCI state.

[0129] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated DL / joint TCI state according to the first TAG, and further release the downlink resources associated with the first DL / joint TCI state.

[0130] Embodiment 1-2-1: Release the Hybrid Automatic Repeat reQuest (HARQ) buffer corresponding to the PDSCH applying the first DL / joint TCI state.

[0131] For example, when the timer corresponding to the first TAG times out, the terminal device may determine the associated DL / joint TCI state according to the first TAG, and further release the HARQ cache corresponding to the PDSCH to which the DL / joint TCI state is applied.

[0132] That is, the resources associated with the first parameter include the HARQ cache corresponding to the PDSCH to which the first DL / joint TCI state is applied.

[0133] In some embodiments, PDSCH can be transmitted through a HARQ process, and the HARQ process can correspond to a HARQ buffer at the receiving end for soft combining of received data. When the timer corresponding to the first TAG times out, the terminal device loses uplink synchronization with the first network node, so it is not necessary to receive or process the PDSCH of the first network node, so the HARQ buffer corresponding to the PDSCH of the first DL / joint TCI state associated with the first TAG can be released.

[0134] Embodiment 1-2-2: Release the pre-configured PDSCH resources applying the first DL / joint TCI state.

[0135] For example, when the timer corresponding to the first TAG times out, the terminal device may determine the associated DL / joint TCI state according to the first TAG, and further release the pre-configured PDSCH resources to which the DL / joint TCI state is applied.

[0136] That is, the resources associated with the first parameter include pre-configured PDSCH resources applying the first DL / joint TCI state.

[0137] Optionally, the pre-configured PDSCH resources include configured downlink assignment (Configured DLassignment).

[0138] In some embodiments, the network device can pre-configure the DL / jointTCI state for the Configured DL assignment, and can further activate or indicate the target DL / joint TCI state. Then, when the timer corresponding to the first TAG expires, the terminal device can determine that uplink desynchronization has occurred to the first network node. Therefore, there is no need to receive or process the PDSCH of the first network node, and thus the pre-configured PDSCH resources of the DL / joint TCI state associated with the first TAG can be released.

[0139] It should be understood that the above-mentioned Embodiment 1-2-1 and Embodiment 1-2-2 may be implemented separately or in combination.

[0140] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated DL / joint TCI state based on the first TAG, and further release the HARQ cache corresponding to the PDSCH applying the DL / joint TCI state and the pre-configured PDSCH resources applying the DL / joint TCI state.

[0141] Optionally, in this embodiment 1-1, the downlink resources associated with the first DL / joint TCI state may include at least one of the following:

[0142] Applying the HARQ buffer corresponding to the PDSCH of the first DL / joint TCI state;

[0143] The pre-configured PDSCH resources of the first DL / joint TCI state are applied.

[0144] It should also be understood that the above-mentioned Embodiment 1-1 and Embodiment 1-2 may be implemented separately or in combination.

[0145] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated UL / joint TCI state and DL / joint TCI state based on the first TAG, and can further release the uplink resources associated with the UL / joint TCI state (for example, the uplink resources in Example 1-1-1, Example 1-1-2 and Example 1-1-3) and the downlink resources associated with the DL / joint TCI state (for example, the downlink resources in Example 1-2-1 and Example 1-2-2).

[0146] Embodiment 2: The first parameter includes first spatial relation information.

[0147] The advantage of associating spatial relation information with TAG is that, compared with the scheme of associating TAG with CORESETPoolIndex, the TAG can use the downlink reference signal contained in the spatial relation information as the downlink synchronization time reference, that is, the terminal device can determine the transmission time of PRACH based on the reception time of the downlink reference signal. In addition, in the millimeter wave frequency band, spatial relation information can provide beam-level downlink and uplink synchronization, which is more accurate than the synchronization at the network node level (a network node uses multiple beams for coverage, and multiple beams experience different path transmission delays).

[0148] In some embodiments, spatial relation information may be configured for an uplink channel or an uplink signal, that is, the spatial relation information and the uplink channel or the uplink signal have an associated relationship.

[0149] For example, when the timer corresponding to the first TAG times out, the terminal device may determine the associated spatial relation information according to the first TAG, and further release the uplink resources associated with the spatial relation information.

[0150] Embodiment 2-1: The first spatial relationship information includes first PUCCH spatial relationship information (PUCCH-SpatialRelationInfo).

[0151] That is, the first TAG is associated with the first PUCCH-SpatialRelationInfo.

[0152] In this case, the terminal device can release the PUCCH resource or PUCCH resource group associated with the first PUCCH-SpatialRelationInfo.

[0153] In some embodiments, when the timer corresponding to the first TAG times out, the terminal device may determine the associated PUCCH-SpatialRelationInfo according to the first TAG, and further release the PUCCH resource or PUCCH resource group associated with the PUCCH-SpatialRelationInfo. For example, the resource associated with the first parameter includes a second PUCCH resource or a second PUCCH resource group, wherein the second PUCCH resource or the second PUCCH resource group is the PUCCH resource or PUCCH resource group associated with the first PUCCH-SpatialRelationInfo.

[0154] In some embodiments, the network device may configure (or indicate, activate) PUCCH-SpatialRelationInfo for a PUCCH resource or a PUCCH resource group. In this case, it can be considered that the PUCCH-SpatialRelationInfo can be applied to the PUCCH resource or the PUCCH resource group.

[0155] In some embodiments, the network device may configure (or indicate, activate) one PUCCH-SpatialRelationInfo for a PUCCH resource or a PUCCH resource group (recorded as case 1), or may configure (or indicate, activate) multiple PUCCH-SpatialRelationInfo for a PUCCH resource or a PUCCH resource group (recorded as case 2), for example, two PUCCH-SpatialRelationInfo, in which case the terminal device transmits PUCCH to multiple network nodes. Optionally, the PUCCH transmission of the terminal device to multiple network nodes may adopt a TDM scheme, or may adopt an SFN scheme or an SDM scheme.

[0156] For situation 1, when the timer corresponding to the first TAG times out, the terminal device can determine the associated PUCCH-SpatialRelationInfo according to the first TAG, and further release the PUCCH resources or PUCCH resource group associated with the PUCCH-SpatialRelationInfo.

[0157] For case 2: when the timer corresponding to the first TAG times out, as an implementation method, the second PUCCH resource or the second PUCCH resource group is released, because the terminal device has lost uplink synchronization with the first network node, and the repeated transmission of the PUCCH cannot be completed, so the second PUCCH resource or the second PUCCH resource group can be released. As another implementation method, the second PUCCH resource or the second PUCCH resource group is not released. This is because the terminal device has lost uplink synchronization with the first network node. When the terminal device does not lose uplink synchronization with other network nodes, it can continue to send PUCCH to other network devices.

[0158] In embodiment 2-2, the first spatial relationship information includes first SRS spatial relationship information (SRS-SpatialRelationInfo).

[0159] That is, the first TAG is associated with the first SRS-SpatialRelationInfo.

[0160] Embodiment 2-2-1: Release the SRS resource or SRS resource group associated with the first SRS-SpatialRelationInfo.

[0161] For example, when the timer corresponding to the first TAG times out, the terminal device may determine the associated SRS-SpatialRelationInfo according to the first TAG, and further release the SRS resource or SRS resource group associated with the SRS-SpatialRelationInfo.

[0162] For example, the resource associated with the first parameter includes a second SRS resource or an SRS resource group, wherein the second SRS resource or SRS resource group is the SRS resource or SRS resource group associated with the first SRS-SpatialRelationInfo.

[0163] In some embodiments, the network device may configure an SRS-SpatialRelationInfo for an SRS resource or an SRS resource group.

[0164] Embodiment 2-2-2: Release the preconfigured PUSCH resources associated with the first SRS-SpatialRelationInfo.

[0165] For example, when the timer corresponding to the first TAG times out, the terminal device may determine the associated SRS-SpatialRelationInfo according to the first TAG, and further release the preconfigured PUSCH resources associated with the SRS-SpatialRelationInfo.

[0166] In this embodiment, the network device may configure SRS resources for PUSCH resources, and may configure SRS-SpatialRelationInfo for SRS resources. Then the preconfigured PUSCH resources associated with the first SRS-SpatialRelationInfo may be the PUSCH resources associated with the SRS resources associated with the first SRS-SpatialRelationInfo.

[0167] In some embodiments, the antenna ports of the PUSCH resource and the associated SRS resource are the same.

[0168] In some embodiments, the pre-configured PUSCH resources include PUSCH resources carrying configured UL grants and / or PUSCH resources for semi-persistent channel state information CSI reporting (PUSCH for semi-persistent CSI reporting).

[0169] It should also be understood that the above-mentioned Embodiment 2-1 and Embodiment 2-2 may be implemented separately or in combination.

[0170] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated PUCCH-SpatialRelationInfo and SRS-SpatialRelationInfo based on the first TAG, and further release the PUCCH resources associated with the PUCCH-SpatialRelationInfo and the uplink resources associated with the SRS-SpatialRelationInfo (for example, the uplink resources in Example 2-2-1 and Example 2-2-2).

[0171] Optionally, in this embodiment 3, the uplink resource associated with the first spatial relation information may include at least one of the following:

[0172] The PUCCH resource or PUCCH resource group associated with the first PUCCH-SpatialRelationInfo;

[0173] The SRS resource or SRS resource group associated with the first SRS-SpatialRelationInfo;

[0174] The pre-configured PUSCH resource associated with the first SRS-SpatialRelationInfo.

[0175] Embodiment 3: The first parameter includes a first uplink RRC parameter or a first CORESETPoolIndex.

[0176] Because CORESETPoolIndex is a network node-specific index of the downlink control channel, it can directly express the association between the network node and TAG. Therefore, the association between TAG and CORESETPoolIndex can be used to release resources. In addition, compared with spatial relation information (only applicable to FR2), CORESETPoolIndex is applicable to both FR1 and FR2 frequency bands, and can support multi-TA enhancement in all frequency bands.

[0177] That is, the first TAG is associated with the first uplink RRC parameter or the first CORESETPoolIndex.

[0178] In some embodiments, when the timer corresponding to the first TAG times out, the terminal device may determine the associated uplink RRC parameter or CORESETPoolIndex according to the first TAG, and further release the resources associated with the uplink RRC parameter or CORESETPoolIndex.

[0179] Embodiment 3-1: Release the first uplink RRC parameter or the PUCCH resources associated with the first CORESETPoolIndex.

[0180] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated uplink RRC parameter or CORESETPoolIndex according to the first TAG, and further release the PUCCH resources associated with the uplink RRC parameter or CORESETPoolIndex.

[0181] That is, the resources associated with the first parameter include the first uplink RRC parameter or the PUCCH resources associated with the first CORESETPoolIndex.

[0182] In some embodiments, the network device may configure (or indicate, activate) an uplink RRC parameter or CORESETPoolIndex for the PUCCH resource, that is, the uplink RRC parameter or CORESETPoolIndex and the PUCCH resource have an associated relationship.

[0183] Embodiment 3-2: Release the pre-configured PUSCH resources associated with the first uplink RRC parameter or the first CORESETPoolIndex.

[0184] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated uplink RRC parameter or CORESETPoolIndex according to the first TAG, and further release the pre-configured PUSCH resources associated with the uplink RRC parameter or CORESETPoolIndex.

[0185] That is, the resources associated with the first parameter include the pre-configured PUSCH resources associated with the first uplink RRC parameter or the first CORESETPoolIndex.

[0186] In some embodiments, the pre-configured PUSCH resources may include Type 1 Configured Grant (CG) PUSCH resources and / or Type 2 CG PUSCH resources.

[0187] In some embodiments, the preconfigured PUSCH resource associated with the first uplink RRC parameter or the first CORESETPoolIndex includes at least one of the following:

[0188] Type 1CG PUSCH resources associated with the first uplink RRC parameter or the first CORESETPoolIndex, Type 2CG PUSCH resources associated with the first uplink RRC parameter or the first CORESETPoolIndex, and Type 2CG PUSCH resources activated by the DCI associated with the first uplink RRC parameter or the first CORESETPoolIndex.

[0189] In some embodiments, the network device may configure (or indicate, activate) an uplink RRC parameter or CORESETPoolIndex for Type 1CG PUSCH resources, that is, the uplink RRC parameter or CORESETPoolIndex and the Type 1CG PUSCH resources have an associated relationship.

[0190] In some embodiments, the network device may configure (or indicate, activate) an uplink RRC parameter or CORESETPoolIndex for Type 2CG PUSCH resources, that is, the uplink RRC parameter or CORESETPoolIndex and the Type 2CG PUSCH resources have an associated relationship.

[0191] In some embodiments, Type 2CG PUSCH is related to PDCCH. For example, Type 2CG PUSCH needs to be activated through DCI in PDCCH, and the PDCCH corresponds to an uplink RRC parameter or CORESETPoolIndex. When the timer corresponding to the first TAG expires, the terminal device can determine the associated uplink RRC parameter or CORESETPoolIndex according to the first TAG, further determine the DCI associated with the uplink RRC parameter or CORESETPoolIndex, and then release the Type 2CG PUSCH activated by the DCI.

[0192] Embodiment 3-3: Release the SRS resources or SRS resource set associated with the first uplink RRC parameter or the first CORESETPoolIndex.

[0193] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated uplink RRC parameter or CORESETPoolIndex according to the first TAG, and further release the SRS resource or SRS resource set associated with the uplink RRC parameter or CORESETPoolIndex.

[0194] That is, the resources associated with the first parameter include the SRS resources or SRS resource set associated with the first uplink RRC parameter or the first CORESETPoolIndex.

[0195] In some embodiments, the SRS resources or SRS resource set associated with the first uplink RRC parameter or the first CORESETPoolIndex is a periodic or semi-continuous SRS resource, and the network device can configure the uplink RRC parameter or CORESETPoolIndex for the periodic or semi-continuous SRS resource (or, configure the second uplink RRC parameter or the second CORESETPoolIndex, that is, the parameter corresponding to the second network device). Then, when the timer corresponding to the first TAG times out, the terminal device can determine the associated uplink RRC parameter or CORESETPoolIndex according to the first TAG, and further release the SRS resources or SRS resource set associated with the uplink RRC parameter or CORESETPoolIndex (or, the uplink RRC parameter CORESETPoolIndex other than the uplink RRC parameter or CORESETPoolIndex).

[0196] Embodiment 3-4: Release the HARQ cache corresponding to the DCI-scheduled PDSCH associated with the first uplink RRC parameter or the first CORESETPoolIndex.

[0197] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated uplink RRC parameter or CORESETPoolIndex according to the first TAG, and further release the HARQ cache corresponding to the DCI-scheduled PDSCH associated with the uplink RRC parameter or CORESETPoolIndex.

[0198] That is, the resources associated with the first parameter include the HARQ cache corresponding to the DCI-scheduled PDSCH associated with the first uplink RRC parameter or the first CORESETPoolIndex.

[0199] It should be noted that DCI is transmitted through time-frequency resources, and the association between DCI and uplink RRC parameters or CORESETPoolIndex can be reflected as: the association between DCI and time-frequency resources.

[0200] For example, DCI is sent through CORESET, and each CORESET corresponds to a CORESETPoolIndex (if not configured, the default is "0"), then the association relationship between CORESETPoolIndex and DCI can be the association relationship between DCI and the CORESET that sends the DCI.

[0201] In some embodiments, PDSCH can be transmitted through a HARQ process, and the HARQ process can correspond to a HARQ buffer at the receiving end for soft merging of received data. When the timer corresponding to the first TAG times out, the terminal device loses uplink synchronization with the first network node, so it is not necessary to receive or process the PDSCH of the first network node, so the HARQ buffer corresponding to the DCI-scheduled PDSCH associated with the uplink RRC parameters associated with the first TAG or CORESETPoolIndex can be released.

[0202] Embodiment 3-5: Release the preconfigured PDSCH resources associated with the first uplink RRC parameter or the first CORESETPoolIndex.

[0203] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated uplink RRC parameter or CORESETPoolIndex according to the first TAG, and further release the pre-configured PDSCH resources associated with the uplink RRC parameter or CORESETPoolIndex.

[0204] That is, the resources associated with the first parameter include the first uplink RRC parameter or the pre-configured PDSCH resources associated with the first CORESETPoolIndex.

[0205] Optionally, the pre-configured PDSCH resources include configured downlink assignment (Configured DL assignment), such as Type 2 Configured DL assignment.

[0206] In some embodiments, the network device can activate or deactivate Configured DLassignment through DCI, and the DCI corresponds to an uplink RRC parameter or CORESETPoolIndex. Then, when the timer corresponding to the first TAG times out, the terminal device can determine that uplink desynchronization has occurred to the first network node. Therefore, there is no need to receive or process the PDSCH of the first network node. Therefore, the terminal device can determine the associated uplink RRC parameter or CORESETPoolIndex according to the first TAG, further determine the DCI associated with the uplink RRC parameter or CORESETPoolIndex, and then release the Configured DL assignment activated by the DCI.

[0207] In some embodiments, the first uplink RRC parameter or the resource associated with the first CORESETPoolIndex may include at least one of the following:

[0208] The first uplink RRC parameter or the PUCCH resource associated with the first CORESETPoolIndex;

[0209] The preconfigured PUSCH resources associated with the first uplink RRC parameter or the first CORESETPoolIndex;

[0210] The SRS resource or SRS resource set associated with the first uplink RRC parameter or the first CORESETPoolIndex;

[0211] The HARQ buffer corresponding to the DCI-scheduled PDSCH associated with the first uplink RRC parameter or the first CORESETPoolIndex;

[0212] The pre-configured PDSCH resources associated with the first uplink RRC parameter or the first CORESETPoolIndex.

[0213] It should be understood that the above-mentioned embodiments 3-1 to 3-5 can be implemented separately or in combination.

[0214] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated uplink RRC parameter or CORESETPoolIndex according to the first TAG, and further release the uplink resources and / or downlink resources associated with the uplink RRC parameter or CORESETPoolIndex. For example, release at least two of the PUSCH resources associated with the uplink RRC parameter or CORESETPoolIndex, the pre-configured PUSCH resources, the SRS resources, the HARQ cache corresponding to the DCI-scheduled PDSCH, and the pre-configured PDSCH resources.

[0215] It should also be understood that the above-mentioned Embodiment 1, Embodiment 2 and Embodiment 3 may be implemented separately or in combination.

[0216] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated TCIstate and CORESETPoolIndex based on the first TAG, and further release the uplink resources associated with the TCI state and / or the downlink resources associated with the TCIstate, as well as the uplink resources associated with the CORESETPoolIndex and / or the downlink resources associated with the CORESETPoolIndex.

[0217] For example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated TCI state and spatial relation information based on the first TAG, and further release the uplink resources associated with the TCI state and the downlink resources associated with the TCI state, as well as the uplink resources associated with the spatial relation information.

[0218] For another example, when the timer corresponding to the first TAG times out, the terminal device can determine the associated spatial relation information and CORESETPoolIndex based on the first TAG, and further release the uplink resources associated with the CORESETPoolIndex and / or the downlink resources associated with the CORESETPoolIndex, as well as the uplink resources associated with the spatial relation information and the downlink resources associated with the spatial relation information.
