[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese Patent Application No. 202410174266.1 filed in China on February 7, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of mobile communication technologies, and in particular to a method for sending Cancellation Indication (CI) information, a terminal, a network device, and a storage medium. Background Art

[0004] In some transmission scenarios, for example, when an Ultra-Reliable and Low Latency Communications (URLLC) terminal and an Enhanced Mobile Broadband (eMBB) terminal transmit data on the same resources, the data transmissions of the URLLC and eMBB terminals may interfere with each other, making it difficult for URLLC and eMBB to meet reliability requirements. To resolve these conflicts, an uplink transmission cancellation technology has been proposed.

[0005] The conflicting resources of the eMBB physical uplink shared channel (PUSCH) and URLLC PUSCH are indicated by the uplink (UL) CI. After receiving the UL CI, the eMBB terminal determines whether to cancel the PUSCH transmission based on its own transmission information and the information of the conflicting resources indicated by the UL CI. Among them, for PUSCH, the scope of transmission cancellation starts from the starting point of the conflicting resources to the end position of the current transmission, not just the conflicting resource part. For repeated transmissions, transmission cancellation is performed independently for each repeated transmission. For the sounding reference signal (SRS), the scope of transmission cancellation is only the conflicting symbols.

[0006] The fifth generation of mobile communication technology (5 thIn existing 5G (5G) network deployments, outdoor macro and indoor micro base stations typically use the same frequency. However, it's been observed that macro downlink interference from micro base stations can significantly impact downlink performance for micro base station users. For example, a user near a high-rise window accesses an indoor micro base station, providing both uplink and downlink services. However, the downlink signal from the outdoor macro base station is very strong, causing significant downlink interference for the window user.

[0007] In order to solve the above-mentioned interference problem, the related art proposes a working scenario of downlink (DL) access to a macro station and uplink (UL) access to a micro station. However, in this scenario, the micro station may also have a terminal A of its own cell, or even a terminal A of its own cell performing ultra-reliable and low-latency communications (URLLC) service. When terminal B from the macro station connects UL to the micro station, there may be a conflict between the enhanced mobile broadband (eMBB) service of the macro station terminal B and the URLLC service of the micro station terminal A. The related art can only indicate the CI and preemption indication (PI) information of the macro station to the macro station terminal B, but cannot indicate the CI and PI information of the micro station. How to indicate the URLLC service information of the micro station terminal to the macro station terminal B and cancel the uplink transmission of the macro station terminal B is a problem that needs to be solved. Furthermore, considering the mobility of the terminal, there may be dynamic switching between the UL and micro base stations, as well as dynamic switching between the DL and macro base stations. Even considering the Multi-Transmission Reception Point (M-TRP) mode, the macro and micro base stations may jointly perform uplink reception or downlink transmission. In this case, how to let the terminal know how to perform UL cancellation and DL pre-emption is a problem that needs to be solved. Summary of the Invention

However, the following description describes an NR system for example purposes, and NR terminology is used in most of the following description, although these techniques may also be applicable to applications other than NR system applications.

[0078] The following description provides examples and does not limit the scope, applicability, or configuration set forth in the claims. Changes may be made to the function and arrangement of the elements discussed without departing from the spirit and scope of this disclosure.

For example, the described methods may be performed in an order different from that described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.

[0079] Take the working scenario of a terminal accessing a macro base station in DL and a micro base station in UL as an example:

[0080] a) The serving cell macro base station sends downlink channels and signals such as the synchronization signal block (SSB), CSI reference signal (CSI-RS), physical downlink control channel (PDCCH), and physical downlink shared channel (PDSCH).

[0081] b) The micro base station sends SSB and CSI-RS, and receives uplink channels and signals such as SRS, Physical Uplink Control Channel (PUCCH), and Physical Uplink Shared Channel (PUSCH).

[0082] c) The SSB and CSI-RS of the associated micro station cell identifier (cell ID) are configured to the reference reference signal (reference RS) of the transmission configuration indicator state (TCI state) of the uplink channel or uplink reference signal, which is used to determine the uplink transmit beam when the terminal sends the uplink channel or uplink reference signal; the terminal can determine whether the uplink channel / signal is sent to the macro station or the micro station through the cell ID of the reference RS of the TCI state. For example, if the reference RS of the TCI state of the uplink channel / signal is associated with the serving cell identifier (servingCellID), the uplink channel / signal is sent to the macro station. If the reference RS of the TCI state of the uplink channel / signal is associated with the additional physical cell identifier (additionalPCI), the uplink channel / signal is sent to the micro station.

[0083] In the above scenario or other similar scenarios, the user equipment (UE) may be connected to a first cell (such as the cell indicated by the servingCellID) and one or more other cells (such as the cell indicated by the additionalPCI). At this time, the network may configure the location of the CI information of multiple cells in the downlink control information (DCI) for the terminal. At this time, how the terminal determines the cell to be read and then determines the transmission resources to be canceled is a technical problem that needs to be solved urgently.

[0084] To address at least one of the above issues, an embodiment of the present disclosure provides a method for sending cancellation indication information. When the network configures CI information of multiple cells for a terminal, the method can indicate the CI information that the terminal needs to read. Referring to Figure 1, an embodiment of the present disclosure provides a method for sending cancellation indication information. When applied to the terminal side, the method includes:

[0085] Step 31: Receive first information sent by the network, where the first information is used to indicate the positions of at least two pieces of CI information in the DCI.

[0086] Here, the network may indicate the positions of at least two pieces of CI information in the DCI to the terminal through Radio Resource Control (RRC) signaling or the like.

[0087] Step 32: Receive second information sent by the network, where the second information is used to indicate target CI information among the at least two CI information.

[0088] Here, the target CI information is the CI information that the terminal needs to read. In the embodiment of the present disclosure, the network may be configured with multiple CI information. The target CI information that the terminal needs to read is determined based on the second information. The target CI information may be part or all of the CI information in the at least two CI information indicated in step 31. Optionally, the network can send the second information to the terminal via a Media Access Control (MAC) control element (CE) or other signaling messages. The second information indicates the target CI information in an explicit and / or implicit manner, which will be described below.

[0089] Step 33: Receive the target CI information sent by the network, and determine the canceled transmission resources according to the target CI information.

[0090] Here, the terminal can determine the location of the target CI information in the DCI based on the first information, and then read the target CI information based on the location of the target CI information in the DCI. Then, the terminal can determine the canceled transmission resources based on the target CI information and then cancel the transmission resources.

[0091] Through the above steps, the disclosed embodiment, when the network is configured with multiple CI information, indicates the target CI information to the terminal, enabling the terminal to read the target CI information and cancel the transmission resource. This solution can be applied to scenarios where the terminal accesses at least one additional PCI and / or at least one additional PCI. In such scenarios, it can reduce or avoid strong inter-cell interference, improve data transmission reliability, and enhance transmission performance.

[0092] Several implementations of the target CI information sent by the receiving network in step 33 are provided below. It should be noted that, in this article, the first cell refers to a serving cell (servingCell), for example, a cell identified by a servingCellID. The other cells refer to additional cells, for example, cells identified by additionalPCI. In some scenarios, the first cell may be a macro cell corresponding to a macro station, and the other cells may be micro cells corresponding to a micro station or indoor micro cells corresponding to an indoor pico station.

[0093] Method 1:

[0094] The network sends a first DCI to the terminal, where the first DCI is DCI scrambled by a first radio network temporary identifier (RNTI), and the first DCI includes CI information of a first cell and / or CI information of at least one other cell. At this time, the terminal determines the position of the target CI information in the first DCI based on the first information, and can then read the target CI information from the first DCI.

[0095] Method 2:

[0096] The network sends a second DCI and / or a third DCI to the terminal, where the second DCI is DCI scrambled by the first RNTI, and the third DCI is DCI scrambled by the second RNTI. The second DCI includes CI information corresponding to a first cell, and the third DCI includes CI information corresponding to at least one other cell. At this time, the terminal can determine the position of the target CI information in the second DCI and / or the third DCI based on the first information, and then read the target CI information from the second DCI and / or the third DCI.

[0097] Method 3:

[0098] The network sends a second DCI and / or at least one fourth DCI to the terminal, wherein the second DCI is DCI scrambled by the first RNTI, the at least one fourth DCI is DCI scrambled by a different second RNTI, the second DCI includes CI information corresponding to one first cell, and each of the fourth DCIs includes CI information corresponding to one other cell. At this time, the terminal determines the position of the target CI information in the second DCI and / or at least one fourth DCI based on the first information, and can then read the target CI information from the second DCI and / or at least one fourth DCI.

[0099] Method 4:

[0100] The network sends a second DCI and / or a fifth DCI to the terminal, wherein the second DCI is DCI scrambled by the first RNTI, the fifth DCI is DCI scrambled by the second RNTI, the second DCI includes CI information corresponding to the first cell, and the fifth DCI includes CI information corresponding to the first cell or another cell. At this time, the terminal determines the position of the target CI information in the second DCI and / or the fifth DCI based on the first information, and can then read the target CI information from the second DCI and / or the fifth DCI.

[0101] In the embodiment of the present disclosure, the first cell may be the cell corresponding to servingCellId, and the other cells may be the cells corresponding to additionalPCI. The first RNTI is a Cancellation Indication-Radio Network Temporary Identifier (CI-RNTI), and the second RNTI may be a newly defined RNTI (New-RNTI).

In the case where the reference RS of the QCL in all TCI states activated by the first MAC CE includes SSBs associated with multiple cells, and / or the reference RS of the QCL in all TCI states activated by the first MAC CE includes multiple CS-RSs, and the reference RS of the QCL in the TCI states of the multiple CS-RSs includes SSBs associated with multiple cells, wherein the multiple cells include at least one first cell and at least one other cell, then:

[0108] (1) For the time-frequency resource position of the first PUSCH transmission, the target CI information is the CI information corresponding to the first cell, wherein the TCI state applied by the first PUSCH is that the reference RS of the QCL in the activated TCI state is the TCI state of the SSB associated with the first cell, and / or, the TCI state applied by the first PUSCH is that the reference RS of the QCL in the activated TCI state is a CS-RS, and the reference RS of the QCL in the TCI state of each CS-RS is the TCI state of the SSB associated with the first cell.

[0109] (2) For the time-frequency resource position of the second PUSCH transmission, the target CI information is the CI information corresponding to the other cell, wherein the TCI state applied by the second PUSCH is that the reference RS of the QCL in the activated TCI state is the TCI state of the SSB associated with other cells, and / or, the TCI state applied by the second PUSCH is that the reference RS of the QCL in the activated TCI state is CS-RS, and the reference RS of the QCL in the TCI state of each CS-RS is the TCI state of the SSB associated with other cells.

[0110] Method 2 (implicit indication):

[0111] The terminal receives indication information of the first cell sent by the network, and determines, based on the indication information of the first cell, that the target CI information is CI information corresponding to the first cell.

[0112] Method 3 (explicit instruction):

[0113] The terminal receives a second MAC CE sent by the network, where the second MAC CE includes indication information of other cells, where the other cells are cells corresponding to the target CI information. At this time, the terminal can determine that the target CI information is the CI information corresponding to the other cells based on the indication information included in the second MAC CE.

[0114] Through the above method, the terminal can determine the target CI information from the at least two CI information indicated in the DCI. Then, in step 33, the target CI information is read from the DCI based on the position of the target information indicated by the first information in the at least two CI information. Furthermore, based on the read target CI information, the time-frequency resource location of the uplink transmission to be canceled is determined, and the transmission resource cancellation process is performed.

[0115] For example, if the terminal is currently scheduled to transmit PUSCH to the first cell, the terminal uses the CI information corresponding to the first cell as the target CI information, determines the time-frequency resource position of the PUSCH transmitted by the terminal to the first cell that needs to be canceled, and performs relevant processing for transmission cancellation.

[0116] For another example, if the terminal is currently scheduled to transmit PUSCH to the other cell, the terminal uses the CI information corresponding to the other cell as the target CI information, determines the time-frequency resource position of the transmission that needs to be canceled in the time-frequency resource position of the terminal's transmission of PUSCH to the other cell, and performs relevant processing for transmission cancellation.

[0117] Referring to FIG. 2 , an embodiment of the present disclosure provides a method for sending cancellation indication information, which, when applied to a network device, includes:

[0118] Step 41: Send at least two CI information.

[0119] Here, the network device is configured with at least two pieces of CI information and sends them to the terminal.

[0120] Step 42: Send first information to the terminal, where the first information is used to indicate positions of the at least two pieces of CI information in the downlink control information DCI.

[0121] Here, the first information may be sent via RRC signaling or the like.

[0122] Step 43: Send second information to the terminal, wherein the second information is used to indicate target CI information among the at least two CI information, and the target CI information is CI information used to determine the canceled transmission resources.

[0123] Here, the target CI information may be part or all of the CI information in the at least two CI information indicated in step 41. Optionally, the network device may send the second information to the terminal via MAC CE or other signaling messages.

[0124] Through the above steps, the network device configures multiple CI information for the terminal and, based on the specific scenario, indicates the target CI information to the terminal. The target CI information is part or all of the CI information from the multiple CI information configured by the network device. This provides the target CI information indication, allowing the terminal to cancel transmission resources based on the target CI information. This solution can be applied to scenarios where the terminal accesses at least one additional PCI and / or at least one additional PCI. In these scenarios, it can reduce or avoid strong inter-cell interference, improve data transmission reliability, and enhance transmission performance.

[0125] In the embodiment of the present disclosure, at least two pieces of CI information in step 41 may be sent in a variety of ways, which are described in detail below.

[0126] Method 1:

[0127] The network device sends a first DCI scrambled by a first RNTI, where the first DCI includes CI information of a first cell and / or CI information of at least one other cell.

[0128] Method 2:

[0129] The network device sends a second DCI scrambled by the first RNTI and / or a third DCI scrambled by the second RNTI, wherein the second DCI includes CI information corresponding to a first cell, and the third DCI includes CI information corresponding to at least one other cell.

[0130] Method 3:

[0131] The network device sends a second DCI scrambled by the first RNTI and / or at least one fourth DCI scrambled by a different second RNTI, wherein the second DCI includes CI information corresponding to a first cell, and each fourth DCI includes CI information corresponding to another cell.

[0132] Method 4:

[0133] The network device sends a second DCI scrambled by the first RNTI and / or a fifth DCI scrambled by the second RNTI, wherein the second DCI includes CI information corresponding to a first cell, and the fifth DCI includes CI information corresponding to the first cell or another cell.

[0134] Here, the first cell may be a cell corresponding to servingCellId, and the other cells may be cells corresponding to additionalPCI. The first RNTI is CI-RNTI, and the second RNTI may be a newly defined RNTI (New-RNTI).

[0135] In the above step 43, there are also various ways to send the second information to the terminal, for example:

[0136] Method 1:

[0137] The network device sends a first MAC CE to the terminal, wherein:

[0138] 1. In all TCI states activated by the first MAC CE, the reference RS of the QCL is the SSB associated with the first cell, and / or, the reference RS of the QCL in all TCI states activated by the first MAC CE is the CS-RS, and the reference RS of the QCL in the TCI state of each CS-RS is the SSB associated with the first cell, the target CI information is the CI information corresponding to the first cell; or

[0139] 2. In all TCI states activated by the first MAC CE, the reference RS of the QCL is an SSB associated with other cells, and / or the reference RS of the QCL in all TCI states activated by the first MAC CE is a CS-RS, and the reference RS of the QCL in the TCI state of each CS-RS is an SSB associated with other cells, the target CI information is the CI information corresponding to the other cell; or

[0140] 3. In the case where the reference RS of the QCL in all TCI states activated by the first MAC CE includes SSBs associated with multiple cells, and / or the reference RS of the QCL in all TCI states activated by the first MAC CE includes multiple CS-RSs, and the reference RS of the QCL in the TCI states of the multiple CS-RSs includes SSBs associated with multiple cells, wherein the multiple cells include at least one first cell and at least one other cell:

[0141] (1) For the time-frequency resource position of the first PUSCH transmission, the target CI information is the CI information corresponding to the first cell, wherein the TCI state applied by the first PUSCH is that the reference RS of the QCL in the activated TCI state is the TCI state of the SSB associated with the first cell, and / or, the TCI state applied by the first PUSCH is that the reference RS of the QCL in the activated TCI state is a CS-RS, and the reference RS of the QCL in the TCI state of each CS-RS is the TCI state of the SSB associated with the first cell.

[0142] (2) For the time-frequency resource position of the second PUSCH transmission, the target CI information is the CI information corresponding to the other cell, wherein the TCI state applied by the second PUSCH is that the reference RS of the QCL in the activated TCI state is the TCI state of the SSB associated with other cells, and / or, the TCI state applied by the second PUSCH is that the reference RS of the QCL in the activated TCI state is CS-RS, and the reference RS of the QCL in the TCI state of each CS-RS is the TCI state of the SSB associated with other cells.

[0143] Method 2:

[0145] Method 3:

[0146] The network device sends a second MAC CE to the terminal, where the second MAC CE includes indication information of other cells, the other cells are cells corresponding to the target CI information, and the target CI information is CI information corresponding to the other cells.

[0147] The above describes the method of the embodiment of the present disclosure from the perspectives of the terminal and the network device, respectively. The following further describes the implementation of the above method through several more specific examples.

[0148] Example 1:

[0149] In this example, in addition to configuring the CI information corresponding to servingCellId to the terminal through RRC signaling, the network also configures the CI information corresponding to additionalPCI. The CI information of additionalPCI is additionally indicated in DCI format 2-4 scrambled by the current CI-RNTI, and the CI information applied by the UE is indicated through MAC CE. Table 1 provides an example of the location of each CI information in the DCI, in which X CI information is configured:

[0150] Table 1

[0151] This example includes:

[0152] 1. The network configures the terminal with first CI configuration information corresponding to the macro base station's servingCellId and the first position information of the CI in the DCI (positionInDCI-1) through RRC signaling. Furthermore, the network configures the terminal with second CI configuration information corresponding to the second additionalPCI and the second positionInDCI-2 of the CI in the DCI. Based on positionInDCI-1 and positionInDCI-2 configured by RRC, the terminal can determine the locations to read the CI information corresponding to the servingCellId and the second additionalPCI, respectively.

[0153] 2. The terminal receives the MAC CE sent by the network. The MAC CE can be used to indicate whether the current UL serving cell of the terminal is the cell corresponding to the servingCellId or the additionalPCI, and further indicate the location of the CI information to be read when the terminal receives the DCI indicating the CI information:

[0154] a) Implicit indication 1: TCI state activated in MAC CE:

[0155] i. If the reference RS of QCL in all TCI states activated by MAC CE is the SSB associated with additionalPCI, and / or the reference RS of QCL in TCI state is CSI-RS, and the reference RS of QCL in the TCI state of the CSI-RS is the SSB associated with additionalPCI, the terminal only reads and applies the CI information corresponding to the additionalPCI to determine the time-frequency resource location for canceling PUSCH.

[0156] ii. If the reference RS of the QCL in all TCI states activated by the MAC CE is the SSB of the associated serving cell, and / or the reference RS of the QCL in the TCI state is a CSI-RS, and the reference RS of the QCL in the TCI state of the CSI-RS is the SSB of the associated serving cell, the terminal only reads and applies the CI information corresponding to the serving cell to determine the time-frequency resource location for canceling the PUSCH.

[0157] iii. If the TCI activated by the MAC CE includes the above two types of TCI states, the CI information corresponding to both the serving cell and the additional PCI must be read.

[0158] 1) For the time-frequency resource position of the first PUSCH transmission, the terminal only reads and applies the CI information corresponding to the serving cell to determine the time-frequency resource position of the canceled PUSCH, wherein the TCI state applied by the first PUSCH is that the reference RS of the QCL in the activated TCI state is the TCI state of the SSB associated with the serving cell, and / or, the TCI state applied by the first PUSCH is that the reference RS of the QCL in the activated TCI state is CS-RS, and the reference RS of the QCL in the TCI state of each CS-RS is the TCI state of the SSB associated with the serving cell.

[0159] 2) For the time-frequency resource position of the second PUSCH transmission, the terminal only reads and applies the CI information corresponding to the additionalPCI to determine the time-frequency resource position of the canceled PUSCH, wherein the TCI state of the second PUSCH application is that the reference RS of the QCL in the activated TCI state is the TCI state of the SSB associated with the additionalPCI, and / or, the TCI state of the second PUSCH application is that the reference RS of the QCL in the activated TCI state is CS-RS, and the reference RS of the QCL in the TCI state of each CS-RS is the TCI state of the SSB associated with the additionalPCI.

[0160] b) Implicit indication 2: The third information indicates whether the cell served by the terminal is a serving cell or an additional PCI. When the third information indicates that the cell served by the terminal is a serving cell, the terminal determines the time-frequency resource position for canceling the PUSCH based on the CI associated with the serving cell. When the third information indicates that the cell served by the terminal is an additional PCI, the terminal determines the time-frequency resource position for canceling the PUSCH based on the CI associated with the additional PCI.

[0161] c) Explicit indication: M bits are added to the MAC CE, each bit corresponds to one cell, and the CI information that the terminal needs to read in the DCI indicating the CI is indicated in the form of a bitmap:

[0162] i. For example, the first CI configuration information of the first servingCellId, the second CI configuration information of the second additionalPCI, and the third CI configuration information of the third additionalPCI are configured through RRC signaling. 8 bits are added to the MAC CE, of which 5 bits are reserved and 3 bits correspond to the first servingCellId, the second additionalPCI, and the third additionalPCI, respectively. When the 3 bits are 100, it indicates that the terminal UL is received by the macro base station. In the subsequent DCI indicating the CI, only the CI information corresponding to the first position information positionInDCI-1 needs to be read; when the 3 bits are 110, it indicates that the terminal UL is jointly received by the macro base station and the micro base station corresponding to the second additionalPCI. In the subsequent DCI indicating the CI, the CI information corresponding to the first position information positionInDCI-1 and the second position information positionInDCI-2 needs to be read.

[0163] 3. The terminal receives DCI indicating a CI, where the CI corresponding to the first position corresponds to the CI information of the macro base station serving cell, and the CI corresponding to the second position corresponds to the CI information of the micro base station additionalPCI. The terminal determines whether to read the CI information of the serving cell or the additionalPCI based on the explicit or implicit indication of the MAC CE, and determines the time-frequency resource location to cancel PUSCH transmission based on the CI information.

[0164] Example 2:

[0165] In addition to the DCI scrambled by CI-RNTI, the network device introduces an additional DCI scrambled by New-RNTI to indicate the CI configuration information corresponding to the X additionalPCIs.

[0166] This example has the following technical effects: the existing CI-RNTI scrambled DCI currently has a maximum of 126 bits, and there may be no space to indicate the CI information of the additionalPCI. Therefore, a New-RNTI scrambled DCI is introduced to indicate the CI information of the additionalPCI, solving the problem of insufficient capacity of the CI-RNTI scrambled DCI. For example, the New-RNTI scrambled DCI can be used to provide multiple UEs in a macro station whose working mode is "macro-micro station uplink and downlink decoupling transmission". Table 2 provides an illustration of the location of the CI information in the New-RNTI scrambled DCI, in which X CI information is configured:

[0167] Table 2

[0168] This example includes:

[0169] 1. The network configures a maximum of X additionalPCIs, the CI information corresponding to each additionalPCI, the position of the CI information in the DCI (positionInDCI), and a New-RNTI value corresponding to the CI information to the UE through RRC signaling.

[0170] 2. The terminal receives the MAC CE and can display or implicitly indicate the current UL serving cell information of the terminal through the MAC CE, thereby indicating whether the terminal should use CI-RNTI or New-RNTI to blindly detect DCI to read CI information.

[0171] a) Implicit indication 1: TCI state activated in MAC CE:

[0172] i. If the reference RS of QCL in all TCI states activated by MAC CE is the SSB associated with additionalPCI, and / or the reference RS of QCL in TCI state is CSI-RS, and the reference RS of QCL in the TCI state of the CSI-RS is the SSB associated with additionalPCI, the terminal only blindly detects the DCI scrambled by New-RNTI corresponding to the additionalPCI, and reads and applies the CI information of the corresponding position of the additionalPCI to determine the time-frequency resource position for canceling PUSCH.

[0173] ii. If the reference RS of the QCL in all TCI states activated by the MAC CE is the SSB of the associated serving cell, and / or the reference RS of the QCL in the TCI state is the CSI-RS, and the reference RS of the QCL in the TCI state of the CSI-RS is the SSB of the associated serving cell, the terminal only blindly detects the DCI scrambled by the CI-RNTI and applies the CI information corresponding to the serving cell to determine the time-frequency resource location for canceling the PUSCH.

[0174] iii. If the TCI activated by the MAC CE includes the two types of TCI states mentioned above, both the CI-RNTI scrambled DCI and the New-RNTI scrambled DCI must be blind checked.

[0175] 1) For the time-frequency resource position of the first PUSCH transmission, the terminal only reads and applies the CI information in the CI-RNTI encrypted DCI to determine the time-frequency resource position of the PUSCH to cancel the time-frequency resource position of the PUSCH, wherein the TCI state of the first PUSCH application is the reference RS of the QCL in the activated TCI state is the TCI state of the SSB associated with the serving cell, and / or, the TCI state of the first PUSCH application is the reference RS of the QCL in the activated TCI state is CS-RS, and the reference RS of the QCL in the TCI state of each CS-RS is the TCI state of the SSB associated with the serving cell.

[0176] 2) For the time-frequency resource position of the second PUSCH transmission, the terminal only reads and applies the CI information in the New-RNTI encrypted DCI to determine the time-frequency resource position of the canceled PUSCH, wherein the TCI state of the second PUSCH application is that the reference RS of the QCL in the activated TCI state is the TCI state of the SSB associated with the additionalPCI, and / or, the TCI state of the second PUSCH application is that the reference RS of the QCL in the activated TCI state is CS-RS, and the reference RS of the QCL in the TCI state of each CS-RS is the TCI state of the SSB associated with the additionalPCI.

[0177] b) Implicit indication 2: According to the third information, it is indicated whether the cell served by the terminal is a serving cell or an additional PCI. When the third information indicates that the cell served by the terminal is a serving cell, the terminal determines the time-frequency resource position for canceling the PUSCH based on the CI in the DCI scrambled by CI-RNTI. When the third information indicates that the cell served by the terminal is an additional PCI, the terminal determines the time-frequency resource position for canceling the PUSCH based on the CI in the DCI scrambled by New-RNTI.

[0178] c) Explicit indication: X bits are added to the MAC CE, each bit corresponds to one cell, and indicates in the form of a bit map which RNTI scrambled DCI the terminal needs to read, as well as the CI information that needs to be read in the DCI:

[0179] i. Example: The RRC configures the first CI configuration information for the first servingCellId, the second CI configuration information for the second additionalPCI, and the third CI configuration information for the third additionalPCI. 8 bits are added to the MAC CE, of which 5 bits are reserved and 3 bits correspond to the first servingCellId, the second additionalPCI, and the third additionalPCI, respectively. When the 3 bits are 100, it indicates that the terminal UL is received by the macro base station and only the CI-RNTI-scrambled DCI needs to be read subsequently. When the 3 bits are 110, it indicates that the terminal UL is received jointly by the macro base station and the micro base station corresponding to the second additionalPCI, and it needs to read both the CI-RNTI-scrambled DCI and the New-RNTI-scrambled DCI.

[0180] 4. The terminal determines whether to blindly detect the CI-RNTI scrambled DCI or the New-RNTI scrambled DCI according to the explicit or implicit indication of the MAC CE, and determines the time-frequency resource location for canceling the PUSCH transmission according to the CI information in the DCI.

[0181] Example 3:

[0182] In addition to the CI-RNTI scrambled DCI, the network device introduces up to X New-RNTI scrambled DCIs to indicate the CI information corresponding to the X additionalPCIs. The New-RNTI scrambled DCI may be a group common DCI of the cell corresponding to the additionalPCI. Table 3 provides an example of the location of the CI information in the New-RNTI scrambled DCI:

[0183] Table 3

[0184] This example includes:

[0185] 1. The network configures a maximum of X additionalPCIs for the UE through RRC signaling, as well as the CI information corresponding to each additionalPCI, the position of the CI information in the DCI (positionInDCI), and the New-RNTI value corresponding to the CI information.

[0186] 2. The terminal receives the MAC CE and can display or implicitly indicate the terminal's current UL serving cell information through the MAC CE, thereby indicating which RNTI the terminal should use for blind detection of DCI to read CI information:

[0187] a) Implicit indication 1: TCI state activated in MAC CE:

[0188] i. If the reference RS of QCL in all TCI states activated by MAC CE is the SSB associated with the first additionalPCI, and / or the reference RS of QCL in the TCI state is CSI-RS, and the reference RS of QCL in the TCI state of the CSI-RS is the SSB associated with the first additionalPCI, the terminal only blindly detects the DCI scrambled by the first New-RNTI corresponding to the first additionalPCI, and reads and applies the CI information of the corresponding position of the first additionalPCI to determine the time-frequency resource position for canceling PUSCH.

[0189] ii. If the reference RS of the QCL in all TCI states activated by the MAC CE is the SSB of the associated serving cell, and / or the reference RS of the QCL in the TCI state is the CSI-RS, and the reference RS of the QCL in the TCI state of the CSI-RS is the SSB of the associated serving cell, the terminal only blindly detects the DCI scrambled by the CI-RNTI and applies the CI information corresponding to the serving cell to determine the time-frequency resource location for canceling the PUSCH.

[0190] iii. If the TCI activated by the MAC CE includes the above two types of TCI states, both the CI-RNTI scrambled DCI and the first New-RNTI scrambled DCI must be blind checked. Further:

[0191] 1) For the time-frequency resource position of the first PUSCH transmission, the terminal only reads and applies the CI information in the CI-RNTI encrypted DCI to determine the time-frequency resource position of the canceled PUSCH, wherein the TCI state applied by the first PUSCH is the reference RS of the QCL in the activated TCI state is the TCI state of the SSB associated with the serving cell, and / or, the TCI state applied by the first PUSCH is the reference RS of the QCL in the activated TCI state is CS-RS, and the reference RS of the QCL in the TCI state of each CS-RS is the TCI state of the SSB associated with the serving cell.

[0192] 2) For the time-frequency resource position of the second PUSCH transmission, the terminal only reads and applies the CI information in the first New-RNTI-scrambled DCI to determine the time-frequency resource position of the canceled PUSCH, wherein the TCI state of the second PUSCH application is that the reference RS of the QCL in the activated TCI state is the TCI state of the SSB associated with additionalPCI, and / or, the TCI state of the second PUSCH application is that the reference RS of the QCL in the activated TCI state is CS-RS, and the reference RS of the QCL in the TCI state of each CS-RS is the TCI state of the SSB associated with additionalPCI.

[0193] b) Implicit indication 2: According to the third information, it is indicated whether the cell served by the terminal is a serving cell or the first additional PCI. When the third information indicates that the cell served by the terminal is a serving cell, the terminal determines the time-frequency resource position for canceling the PUSCH based on the CI in the DCI scrambled by the CI-RNTI. When the third information indicates that the cell served by the terminal is the first additional PCI, the terminal determines the time-frequency resource position for canceling the PUSCH based on the CI in the DCI scrambled by the first New-RNTI.

[0194] c) Explicit indication: X bits are added to the MAC CE, each bit corresponds to one cell, and indicates in the form of a bit map which RNTI scrambled DCI the terminal needs to read, as well as the CI information that needs to be read in the DCI

[0195] i. Example: RRC configures the first CI configuration information for the first servingCellId, the second CI configuration information for the second additionalPCI, and the third CI configuration information for the third additionalPCI. 8 bits are added to the MAC CE, of which 5 bits are reserved and 3 bits correspond to the first servingCellId, the second additionalPCI, and the third additionalPCI, respectively. When the 3 bits are 100, it indicates that the terminal UL is received by the macro base station and only the CI-RNTI-scrambled DCI needs to be read subsequently. When the 3 bits are 110, it indicates that the terminal UL is jointly received by the macro base station and the micro base station corresponding to the second additionalPCI. Subsequently, the CI-RNTI-scrambled DCI and the second New-RNTI-scrambled DCI need to be read.

[0196] 3. The terminal determines whether to blindly detect the CI-RNTI scrambled DCI or the first New-RNTI scrambled DCI according to the explicit or implicit indication of the MAC CE, and determines the time-frequency resource location for canceling PUSCH transmission according to the CI information in the DCI.

[0197] Example 4:

[0198] In addition to the CI-RNTI scrambled DCI, the network device introduces an additional New-RNTI scrambled DCI to indicate the CI configuration information corresponding to the servingCellID or additionalPCI. Table 4 provides an example of the location of the CI information in the New-RNTI scrambled DCI:

[0199] Table 4

[0200] In this example, the terminal determines the time-frequency resource location for canceling PUSCH transmission according to the CI information in the DCI.
