Description

[0001] This application claims priority to Chinese Patent Application No. 202010100097.9, filed on February 18, 2020, entitled "Electronic Device, Wireless Communication Method and Computer-Readable Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] The embodiments of this disclosure generally relate to the field of wireless communication, and more specifically to electronic devices, wireless communication methods, and computer-readable storage media. More specifically, this disclosure relates to an electronic device as a network-side device in a wireless communication system, an electronic device as a user device in a wireless communication system, a wireless communication method performed by a network-side device in a wireless communication system, a wireless communication method performed by a user device in a wireless communication system, and a computer-readable storage medium. Background Technology

[0003] In a Single Frequency Network (SFN), multiple Remote Radio Heads (RRHs) transmit the same content to the User Equipment (UE), thereby improving the reliability of the UE during downlink reception.

[0004] The Transmission Configuration Indication (TCI) state corresponds to either the Channel State Information-Reference Signal (CSI-RS) or the Synchronization Signal Block (SSB) and can be used to indicate to the UE the direction of the transmit beam used by the network-side equipment. The network-side equipment can configure multiple TCI states for the UE, each corresponding to a reference signal (CSI-RS or SSB), i.e., the direction of a transmit beam. Optionally, the network-side equipment can activate one or more of the UE's configured TCI states. Furthermore, for the PDSCH, the network-side equipment can dynamically indicate one of the configured or activated TCI states, thereby allowing the UE to know the direction of the transmit beam to be used by the network-side equipment.

[0005] In an SFN, the direction of the transmit beam for each RRH may be different, thus requiring the UE to use multiple corresponding receive beams for reception. In the traditional TCI state configuration, activation, and dynamic indication process, only one TCI state can be activated or dynamically indicated at a time, meaning only the direction of one transmit beam can be indicated to the UE. In other words, the UE cannot determine the directions of multiple transmit beams, and consequently, multiple receive beams, through a single activation or dynamic indication.

[0006] Furthermore, if the UE is in a high-speed movement state, it may quickly move from one cell to a neighboring cell. In the traditional TCI state configuration, activation, and dynamic indication process, only the TCI state corresponding to the transmit beam from the UE's serving cell can be configured, activated, and dynamically indicated. That is, when the UE moves to a neighboring cell, the UE needs to be reconfigured for its TCI state. Therefore, the UE needs to be configured for its TCI state frequently.

[0007] Therefore, it is necessary to propose a technical solution to solve at least one of the above technical problems, thereby optimizing the configuration, activation and dynamic indication process of TCI status. Summary of the Invention

[0008] This section provides a general overview of this disclosure, rather than a full disclosure of its entire scope or all its features.

[0009] The purpose of this disclosure is to provide an electronic device, a wireless communication method, and a computer-readable storage medium to optimize the configuration, activation, and dynamic indication process of TCI status.

[0010] According to one aspect of this disclosure, an electronic device is provided, including processing circuitry configured to: configure a user equipment with a plurality of TCI states corresponding to a plurality of transmit beams, the plurality of transmit beams originating from at least two cells; and send indication information to the user equipment to indicate two or more of the plurality of TCI states, or send activation information to the user equipment to activate two or more of the plurality of TCI states.

[0011] According to another aspect of this disclosure, an electronic device is provided, including processing circuitry configured to: configure a plurality of TCI states corresponding to a plurality of transmit beams, the plurality of transmit beams originating from at least two cells; receive indication information or activation information from a network-side device to determine two or more indicated or activated TCI states among the plurality of TCI states; and determine a receive beam based on the transmit beams corresponding to the two or more TCI states.

[0012] According to another aspect of this disclosure, a wireless communication method performed by an electronic device is provided, comprising: configuring a user equipment with a plurality of TCI states corresponding to a plurality of transmit beams, the plurality of transmit beams originating from at least two cells; and sending indication information to the user equipment to indicate two or more of the plurality of TCI states, or sending activation information to the user equipment to activate two or more of the plurality of TCI states.

[0013] According to another aspect of this disclosure, a wireless communication method performed by an electronic device is provided, comprising: configuring a plurality of TCI states corresponding to a plurality of transmit beams, the plurality of transmit beams originating from at least two cells; receiving indication information or activation information from a network-side device to determine two or more indicated or activated TCI states among the plurality of TCI states; and determining a receive beam based on the transmit beams corresponding to the two or more TCI states.

[0014] According to another aspect of this disclosure, a computer-readable storage medium is provided, including executable computer instructions that, when executed by a computer, cause the computer to perform the wireless communication method according to this disclosure.

[0015] According to another aspect of this disclosure, a computer program is provided that, when executed by a computer, causes the computer to perform the wireless communication method according to this disclosure.

[0016] Using the electronic device, wireless communication method, and computer-readable storage medium according to this disclosure, a network-side device can configure multiple TCI states for at least two cells for a user equipment (UE), and can send indication or activation information to the UE to indicate or activate two or more of the multiple TCI states. In this way, the network-side device can configure the TCI states of multiple cells for the UE, thereby reducing the frequency of TCI state configuration for the UE. Furthermore, the indication or activation information can indicate or activate multiple TCI states, allowing the UE to determine multiple transmit beams corresponding to the multiple TCI states, and thus determine multiple receive beams. In summary, the electronic device, wireless communication method, and computer-readable storage medium according to this disclosure can optimize the TCI state configuration, activation, and dynamic indication process.

[0039] While this disclosure is readily subject to various modifications and substitutions, specific embodiments thereof have been shown by way of example in the accompanying drawings and are described in detail herein. However, it should be understood that the description of specific embodiments herein is not intended to limit this disclosure to the specific forms disclosed, but rather, this disclosure is intended to cover all modifications, equivalents, and substitutions falling within the spirit and scope of this disclosure. It should be noted that throughout the drawings, corresponding reference numerals indicate corresponding parts. Detailed Implementation

[0040] Examples of this disclosure will now be described more fully with reference to the accompanying drawings. The following description is merely exemplary and is not intended to limit the disclosure, its application, or its uses.

[0041] Example embodiments are provided so that this disclosure will become exhaustive and will fully convey its scope to those skilled in the art. Numerous specific details, such as examples of particular components, apparatus, and methods, are set forth to provide a detailed understanding of embodiments of this disclosure. It will be apparent to those skilled in the art that the specific details are not required, and that the example embodiments may be implemented in many different forms, none of which should be construed as limiting the scope of this disclosure. In some example embodiments, well-known processes, well-known structures, and well-known techniques are not described in detail.

[0042] The description will proceed in the following order:

[0043] 1. Scene description;

[0044] 2. Configuration example of network-side devices;

[0045] 3. User equipment configuration example;

[0046] 4. Method Implementation Examples;

[0047] 5. Application examples.

[0048] <1. Scene Description>

[0049] Figure 1 This is a schematic diagram illustrating a scenario where a user device is located in a vehicle traveling on a highway or railway. For example... Figure 1 The diagram illustrates three cells along a highway or railway line: cell A, cell B, and cell C. Each cell's base station equipment can be implemented by connecting multiple RRHs (Regular Radio Hierarchical Units) to a single BBU (Base Band Unit). RRHs connected to the same BBU share the same cell ID, thereby reducing the number of cell handovers and the resulting handover latency. Figure 1 As shown, each cell's BBU can connect to three RRHs. Furthermore, each RRH can have one or more transmit beam directions. For example, in... Figure 1 In this context, RRH2 and RRH3 in cell B and RRH on the left side of cell C can each have two transmission beam directions.

[0050] As mentioned earlier, in the traditional TCI state configuration, activation, and dynamic indication process, only one TCI state can be activated or dynamically indicated at a time, meaning only the direction of one transmit beam can be indicated to the UE. In other words, the UE cannot determine the directions of multiple transmit beams, and thus the directions of multiple receive beams, through a single activation or dynamic indication. Furthermore, in Figure 1In the scenario shown, the UE is located on a highway or high-speed railway, thus being in a state of high-speed movement. The UE quickly moves from cell A to cell B, and then to cell C. In the traditional configuration, activation, and dynamic indication process of TCI state, only the TCI state corresponding to the transmit beam of the UE's serving cell can be configured, activated, and dynamically indicated. That is, when the UE is within the service range of cell A, cell A configures the TCI state corresponding to the transmit beam direction of cell A's RRH; when the UE enters the service range of cell B, cell B configures the TCI state corresponding to the transmit beam direction of cell B's RRH; and when the UE enters the service range of cell C, cell C configures the TCI state corresponding to the transmit beam direction of cell C's RRH. Therefore, the UE needs to be configured with its TCI state frequently.

[0051] This disclosure provides an electronic device in a wireless communication system, a wireless communication method performed by the electronic device in the wireless communication system, and a computer-readable storage medium for such scenarios to optimize the configuration, activation, and dynamic indication process of TCI states.

[0052] It is worth noting that, Figure 1 This disclosure illustrates only one typical scenario, and the scenarios described herein are not limited to this. For example, in another scenario, each cell's base station equipment is implemented through multiple TRPs (Transmit Receive Points), each TRP may have one or more transmit beam directions, and each TRP transmits the same content to the user equipment. This disclosure is applicable to all scenarios that require optimization of the configuration, activation, and dynamic indication processes of TCI status.

[0053] The wireless communication system according to this disclosure can be a 5G NR (New Radio) communication system.

[0054] According to this disclosure, the network-side equipment can be any type of base station equipment, such as an eNB or a gNB (a base station in a 5G communication system).

[0055] According to this disclosure, the user equipment can be a mobile terminal (such as a smartphone, tablet PC, laptop PC, portable gaming terminal, portable / dongle-type mobile router, and digital camera device) or an in-vehicle terminal (such as a car navigation device). The user equipment can also be implemented as a terminal performing machine-to-machine (M2M) communication (also known as a machine-type communication (MTC) terminal). Furthermore, the user equipment can be a wireless communication module (such as an integrated circuit module comprising a single chip) installed on each of the aforementioned terminals.

[0056] <2. Configuration Example of Network-Side Devices>

[0057] Figure 2 This is a block diagram illustrating an example configuration of an electronic device 200 according to an embodiment of the present disclosure. The electronic device 200 here can serve as a network-side device in a wireless communication system, specifically as a base station device in the wireless communication system.

[0058] like Figure 2 As shown, the electronic device 200 may include a configuration unit 210, an activation unit 220, an indication unit 230, and a communication unit 240.

[0059] Here, each unit of the electronic device 200 can be included in the processing circuit. It should be noted that the electronic device 200 may include one or more processing circuits. Furthermore, the processing circuit may include various discrete functional units to perform various different functions and / or operations. It should be noted that these functional units can be physical entities or logical entities, and units with different names may be implemented by the same physical entity.

[0060] According to embodiments of this disclosure, configuration unit 210 can configure multiple TCI states for user equipment, each corresponding to a plurality of transmit beams. Here, the plurality of transmit beams originate from at least two cells.

[0061] According to embodiments of this disclosure, activation unit 220 can determine which TCI states among the multiple TCI states configured by configuration unit 210 need to be activated, and can generate and send activation information to notify user equipment of the two or more activated TCI states.

[0062] According to embodiments of this disclosure, electronic device 200 can send activation information to user equipment via communication unit 240 to notify user equipment of two or more active TCI states among a plurality of TCI states.

[0063] According to embodiments of this disclosure, the indication unit 230 can determine which TCI states among the multiple TCI states configured by the configuration unit 210 need to be indicated, and can generate indication information to notify the user equipment of the two or more indicated TCI states.

[0064] According to embodiments of this disclosure, electronic device 200 can send indication information to user equipment via communication unit 240 to notify user equipment of two or more indicated TCI states among a plurality of TCI states.

[0065] As described above, the electronic device 200 according to this disclosure can configure multiple TCI states for at least two cells for a user equipment, and can send indication information or activation information to the user equipment to indicate or activate two or more of the multiple TCI states. In this way, the electronic device 200 can configure the TCI states of multiple cells for the user equipment, thereby reducing the frequency of TCI state configuration for the user equipment. Furthermore, the indication information or activation information can indicate or activate multiple TCI states, allowing the user equipment to determine multiple transmit beams corresponding to the multiple TCI states, and thus determine multiple receive beams. Since multiple transmit beams transmit the same content, the accuracy of data received by the user equipment can be improved. In summary, the embodiments according to this disclosure can optimize the TCI state configuration, activation, and dynamic indication process.

[0066] According to embodiments of this disclosure, the TCI state corresponds to a reference signal (CSI-RS or SSB), and the reference signal corresponds to a transmit beam. Therefore, the TCI state can be used to indicate the direction of the transmit beam. The configuration, activation, and dynamic indication processes of the TCI state differ slightly for PDSCH and PDCCH; therefore, the configuration, activation, and dynamic indication processes of the TCI state will be described below for PDSCH and PDCCH respectively.

[0067] For the PDSCH (downlink data signal), the configuration unit 210 can configure multiple TCI states for the user equipment, thereby enabling the indication unit 230 to send indication information to the user equipment to dynamically indicate multiple TCI states among the multiple TCI states configured by the configuration unit 210. Optionally, the configuration unit 210 can configure multiple TCI states for the user equipment, the activation unit 220 can send activation information to the user equipment to indicate which TCI states among the multiple TCI states configured by the configuration unit 210 are activated, and the indication unit 230 can send indication information to the user equipment to dynamically indicate multiple TCI states among the multiple TCI states activated by the activation unit 220. Here, the TCI states dynamically indicated by the indication unit 230 are used to indicate the transmit beam for transmitting the PDSCH. The dynamically indicated TCI states correspond to the transmit beam used for the PDSCH. That is, the electronic device 200 intends to use the transmit beam corresponding to the dynamically indicated TCI states to transmit the PDSCH. According to embodiments of this disclosure, the electronic device 200 can carry configuration information for the PDSCH via RRC (Radio Resource Control) signaling, activation information for the PDSCH via MAC (Media Access Control) CE (control element), and indication information for the PDSCH via DCI (Downlink Control Information).

[0068] For the PDCCH (Downlink Control Signal), the configuration unit 210 can configure multiple TCI states for the user equipment, thereby enabling the activation unit 220 to send activation information to the user equipment to indicate which TCI states among the multiple TCI states configured by the configuration unit 210 are activated. Here, the TCI states activated by the activation unit 220 are used to indicate the transmit beam for transmitting the PDCCH. The activated TCI states correspond to the transmit beam used for the PDCCH. That is, the electronic device 200 expects to use the transmit beam corresponding to the activated TCI states to transmit the PDCCH. According to embodiments of this disclosure, the electronic device 200 can carry configuration information for the PDCCH via RRC signaling and activation information for the PDCCH via MAC CE.

[0069] First Embodiment

[0070] PDSCH

[0071] TCI status configuration

[0072] Configuration unit 210 can configure multiple TCI states for user equipment, each corresponding to a multiple transmit beam. Here, the multiple transmit beams come from at least two cells.

[0073] According to embodiments of this disclosure, multiple transmit beams can originate from the serving cell and non-serving cells of the user equipment. For example, multiple transmit beams can originate from at least two cells along the user equipment's travel route. Here, the electronic device 200 can predict the user equipment's travel route in advance and determine multiple cells that will be passed along the route, so that the configuration unit 210 can configure the user equipment with TCI states corresponding to the transmit beams from these multiple cells. For highway or high-speed rail scenarios, the user equipment's travel route is fixed, and the electronic device 200 can directly determine multiple cells along the travel route based on the deployment of the highway or high-speed rail, so that the configuration unit 210 can configure the user equipment with TCI states corresponding to the transmit beams from these multiple cells.

[0074] According to embodiments of this disclosure, the configuration unit 210 can set the TCI state position according to the location of each cell. For example, if the user equipment passes through cell A, cell B, and cell C in sequence, the configured TCI state order will also be the TCI state corresponding to the transmit beam of cell A, the TCI state corresponding to the transmit beam of cell B, and the TCI state corresponding to the transmit beam of cell C. Furthermore, within each cell, the configuration unit 210 can also set the TCI state position according to the order of each RRH. For example, if the user equipment passes through RRH1, RRH2, and RRH3 in sequence, the configured TCI state order will also be the TCI state corresponding to the transmit beam of RRH1, the TCI state corresponding to the transmit beam of RRH2, and the TCI state corresponding to the transmit beam of RRH3.

[0075] According to embodiments of this disclosure, the electronic device 200 can determine how many transmit beams from cells to configure TCI states for the user equipment based on the number of TCI states that the configuration unit 210 can configure. Preferably, the configuration unit 210 can configure up to 128 TCI states. Of course, the number of TCI states configured by the configuration unit 210 can change as technology advances and standards are updated.

[0076] According to embodiments of this disclosure, each TCI state configured by configuration unit 210 may include: a reference signal corresponding to the TCI state and identification information of the cell to which the transmit beam corresponding to the TCI state belongs. The following shows pseudocode for TCI state information according to embodiments of this disclosure. Wherein, TCI-StateId represents the ID of the TCI state, ServCellIndex represents the identifier of the serving cell of the user equipment, PCI represents the identifier of the cell to which the transmit beam corresponding to the TCI state belongs, NZP-CSI-RS-ResourceId represents the ID of the CSI-RS resource corresponding to the TCI state, and SSB-Index represents the ID of the SSB corresponding to the TCI state.

[0077]

[0078] Figure 3 This illustrates an embodiment of the present disclosure. Figure 1 A diagram illustrating the TCI status configuration for a given scenario. Figure 1 The diagram shows three cells along the user equipment's travel route: cell A, cell B, and cell C. Each cell includes three transmit hoods (RRHs), and it is assumed that each RRH has two transmit beams, meaning each cell has six transmit beams. Figure 3 As shown, configuration unit 210 can configure 18 TCI states for user equipment: TCI states 1-18, each TCI state corresponding to a transmit beam. That is, TCI states 1-6 correspond to the six transmit beams of cell A, TCI states 7-12 correspond to the six transmit beams of cell B, and TCI states 13-18 correspond to the six transmit beams of cell C. Figure 3 In the example shown, the 18 TCI states can be configured for the user equipment (UE) by the serving base station equipment before the UE passes through cell A, thus eliminating the need for the UE to be configured with TCI states again when passing through cells A and B. When the UE passes through cell C, the base station equipment in cell C can configure the UE with TCI states corresponding to the transmit beams of the subsequent cells. Therefore, according to the embodiments of this disclosure, the number of times the UE needs to be configured with TCI states can be reduced.

[0079] Activation of TCI state

[0080] According to embodiments of this disclosure, activation unit 220 can determine which TCI states among the multiple TCI states configured by user equipment activation configuration unit 210 are active. This is because the configuration unit configures a large number of TCI states, which would incur significant overhead for subsequent indication unit 230 when dynamically indicating TCI states. Therefore, activation unit 220 can pre-activate some TCI states to reduce subsequent overhead.

[0081] According to embodiments of this disclosure, when a user equipment is located on a highway or high-speed railway, a TCI state corresponding to the transmit beam of a cell can be activated for the user equipment as it is about to pass through a cell. Preferably, the activation unit 220 activates a maximum of eight TCI states at a time. Of course, with technological advancements and standard updates, the maximum number of TCI states activated by the activation unit 220 can be changed.

[0082] Figure 4 This is a schematic diagram illustrating the activated TCI state for PDSCH according to an embodiment of the present disclosure. Figure 4 As shown, when a user equipment is about to pass through cell B, the serving base station equipment at that time can activate TCI states 7-12. The gray area shows the activated TCI states.

[0083] Dynamic indication of TCI status

[0084] According to embodiments of this disclosure, the indication unit 230 can determine the TCI states that need to be dynamically indicated, i.e., the TCI states corresponding to the transmit beam from which the PDSCH will be transmitted. Here, the dynamically indicated TCI states can be multiple TCI states configured by the configuration unit 210, or multiple TCI states activated by the activation unit 220. Further, the indication unit 230 can generate indication information to notify the user equipment of the two or more indicated TCI states.

[0085] According to embodiments of this disclosure, the indication information includes information for identifying a specific TCI state among a plurality of TCI states configured by the configuration unit 210 or a plurality of TCI states activated by the activation unit 220, and each specific TCI state has an associated TCI state. Thus, the user equipment can determine a specific TCI state and the TCI state associated with that specific TCI state based on the indication information.

[0086] According to embodiments of this disclosure, the TCI states associated with a specific TCI state may include TCI states that are a predetermined number of times away from the specific TCI state. That is, the TCI states associated with a specific TCI state may include a predetermined number of TCI states before the specific TCI state and a predetermined number of TCI states after the specific TCI state. For example, if the specific TCI state is TCI state 4 and the predetermined number is 2, then the TCI states associated with the specific TCI state are TCI state 2, TCI state 3, TCI state 5, and TCI state 6.

[0087] According to embodiments of this disclosure, the predetermined number can be 1. That is, the TCI states associated with a particular TCI state include the TCI states adjacent to the particular TCI state, i.e., the TCI states immediately preceding and immediately following the particular TCI state. For example, if the particular TCI state is TCI state 4 and the predetermined number is 1, then the TCI states associated with the particular TCI state are TCI state 3 and TCI state 5.

[0088] According to embodiments of this disclosure, the indication unit 230 can indicate a specific TCI state to the user equipment by including identification information of a specific TCI state in the indication information.

[0089] Figure 5 This is a schematic diagram illustrating the dynamic indication of TCI status for PDSCH according to an embodiment of the present disclosure. Figure 5 As shown, TCI state 8 is a specific TCI state, and the indication information may include identification information of TCI state 8. Based on the TCI state 8 included in the indication information, the user equipment can determine that the TCI state dynamically indicated by the electronic device 200 includes TCI state 7, TCI state 8, and TCI state 9.

[0090] Figure 6 This is a schematic diagram illustrating the dynamic indication of TCI status for PDSCH according to an embodiment of the present disclosure. Figure 6 As shown, TCI state 11 is a specific TCI state, and the indication information may include identification information of TCI state 11. Based on the TCI state 11 included in the indication information, the user equipment can determine that the TCI state dynamically indicated by the electronic device 200 includes TCI state 10, TCI state 11, and TCI state 12.

[0091] According to embodiments of this disclosure, the indication unit 230 can indicate a specific TCI state to the user equipment by including the following difference value in the indication information: the difference between the identification information of the specific TCI state included in the current indication information and the identification information of the specific TCI state included in the previous indication information. That is, the indication information may include the displacement value of the specific TCI state relative to the previous one.

[0092] According to embodiments of this disclosure, when the indication information includes differential values ​​or displacement values, except for the first indication of a specific TCI state which requires the inclusion of the identification information of that specific TCI state, subsequent indications can include only the differential value or displacement value of the specific TCI state, thereby greatly reducing the overhead of the indication information. This eliminates the need for the operation of the activation unit 220. In other words, the indication unit 230 can dynamically indicate multiple TCI states among the multiple TCI states configured by the configuration unit 210 using differential values ​​or displacement values.

[0093] According to embodiments of this disclosure, the difference value or displacement value can be a positive number. Furthermore, the difference value or displacement value can also be a negative number. Further, since the configuration unit 210 has a maximum limit on the number of TCI states it can configure each time, when the user equipment determines, based on the difference value or displacement value, that the identifier of a specific TCI state exceeds the maximum number of TCI states configured by the configuration unit 210, it can restart counting from 0, i.e., a cyclic shift operation.

[0094] Figure 7 This is a schematic diagram illustrating the dynamic indication of TCI status for PDSCH according to an embodiment of the present disclosure. Figure 7 In the example, assuming the specific TCI state included in the previous indication information was TCI state 8, and the specific TCI state included in the current indication information is TCI state 11, then the current indication information may include a difference value 3 (011). Based on the difference value 3, the user equipment can determine that the specific TCI state has shifted by 3 TCI states from TCI state 8, thus determining that the specific TCI state is 11. Then, based on TCI state 11, the user equipment can determine that the TCI states dynamically indicated by the electronic device 200 include TCI states 10, 11, and 12.

[0095] As described above, according to embodiments of this disclosure, for the PDSCH, TCI states corresponding to transmit beams from multiple cells can be configured, thereby reducing the frequency of TCI state configuration for the user equipment. Furthermore, indication information can be sent to the user equipment to indicate two or more of the multiple TCI states, enabling the user equipment to determine multiple transmit beams corresponding to the multiple TCI states, and thus determine multiple receive beams to receive the PDSCH. Since these multiple transmit beams transmit the same content, the accuracy of the signal received by the user equipment can be improved.

[0098] According to the embodiments of this disclosure, the configuration of the TCI state for PDCCH is the same as the configuration of the TCI state for PDSCH, and will not be repeated here.

[0099] Activation of TCI state

[0100] According to embodiments of this disclosure, activation unit 220 can determine the TCI states that need to be activated, i.e., the TCI states corresponding to the transmit beam that will transmit the PDCCH. Here, the activated TCI states can be multiple TCI states configured by configuration unit 210. Further, activation unit 220 can generate activation information to notify user equipment of two or more activated TCI states.

[0101] According to embodiments of this disclosure, activation unit 220 can activate multiple TCI states for each CORESET (Control Resource SET). Here, CORESET represents the resources occupied by the PDCCH to be transmitted, including time-domain resources and frequency-domain resources.

[0102] According to embodiments of this disclosure, the activation information includes information for identifying a specific TCI state among a plurality of TCI states configured by the configuration unit 210, and each specific TCI state has an associated TCI state. Thus, the user equipment can determine the specific TCI state and the TCI state associated with the specific TCI state based on the activation information.

[0103] According to embodiments of this disclosure, the TCI states associated with a specific TCI state may include TCI states that are a predetermined number of times away from the specific TCI state. That is, the TCI states associated with a specific TCI state may include a predetermined number of TCI states before the specific TCI state and a predetermined number of TCI states after the specific TCI state. For example, if the specific TCI state is TCI state 4 and the predetermined number is 2, then the TCI states associated with the specific TCI state are TCI state 2, TCI state 3, TCI state 5, and TCI state 6.

[0104] According to embodiments of this disclosure, the predetermined number can be 1. That is, the TCI states associated with a particular TCI state include the TCI states adjacent to the particular TCI state, i.e., the TCI states immediately preceding and immediately following the particular TCI state. For example, if the particular TCI state is TCI state 4 and the predetermined number is 1, then the TCI states associated with the particular TCI state are TCI state 3 and TCI state 5.

[0105] According to embodiments of this disclosure, activation unit 220 can indicate a specific TCI state to user equipment by including identification information of a specific TCI state in the activation information.

[0106] Figure 8 This is a schematic diagram illustrating the activated TCI state for the PDCCH according to an embodiment of the present disclosure. Figure 8 As shown, TCI state 11 is a specific TCI state, and the activation information may include identification information for TCI state 11. Based on the TCI state 11 included in the activation information, the user equipment can determine that the activated TCI state of the electronic device 200 includes TCI state 10, TCI state 11, and TCI state 12.

[0107] According to embodiments of this disclosure, the activation unit 220 can indicate a specific TCI state to the user equipment by including the following difference value in the activation information: the difference between the identification information of the specific TCI state included in the current activation information and the identification information of the specific TCI state included in the previous activation information. That is, the activation information can include a displacement value of the specific TCI state.

[0108] According to embodiments of this disclosure, when the activation information includes a differential value or a displacement value, except for the first indication of a specific TCI state which requires the inclusion of the identification information of that specific TCI state, each subsequent activation information can include only the differential value or displacement value of the specific TCI state, thereby greatly reducing the overhead of the activation information.

[0109] According to embodiments of this disclosure, the difference value or displacement value can be a positive number. Furthermore, the difference value or displacement value can also be a negative number. Further, since the configuration unit 210 has a maximum limit on the number of TCI states it can configure each time, when the user equipment determines, based on the difference value or displacement value, that the identifier of a specific TCI state exceeds the maximum number of TCI states configured by the configuration unit 210, it can restart counting from 0, i.e., a cyclic shift operation.

[0110] Figure 9 This is a schematic diagram illustrating the activated TCI state for the PDCCH according to an embodiment of the present disclosure. Figure 9In the example, assuming the specific TCI state included in the previous activation information is TCI state 8, and the specific TCI state included in the current activation information is TCI state 11, then the current activation information may include a difference value 3 (011). Based on the difference value 3, the user equipment can determine that the specific TCI state has shifted by 3 TCI states from TCI state 8, thus determining that the specific TCI state is 11. Then, based on TCI state 11, the user equipment can determine that the activated TCI states of the electronic device 200 include TCI states 10, 11, and 12.

[0111] As described above, according to embodiments of this disclosure, for the PDCCH, TCI states corresponding to transmit beams from multiple cells can be configured, thereby reducing the frequency of TCI state configuration for the user equipment. Furthermore, activation information can be sent to the user equipment to activate two or more of the multiple TCI states, enabling the user equipment to determine multiple transmit beams corresponding to the multiple TCI states, and thus determine multiple receive beams to receive the PDCCH. Since these multiple transmit beams transmit the same content, the accuracy of the signal received by the user equipment can be improved.

[0112] Second Embodiment

[0113] PDSCH

[0114] TCI status configuration

[0115] The configuration of the TCI state according to the second embodiment of this disclosure is the same as that according to the first embodiment of this disclosure, and will not be described again here.

[0116] Activation of TCI state

[0117] According to embodiments of this disclosure, electronic device 200 can divide multiple TCI states configured by configuration unit 210 into multiple groups, each group including one or more TCI states, preferably multiple TCI states. The number of TCI states included in each group can be the same or different. For example, electronic device 200 can group TCI states according to the cell and transmit beam location corresponding to the TCI state. For example, electronic device 200 can group TCI states corresponding to transmit beams that are close to each other into one group. In a specific example, electronic device 200 can group TCI states corresponding to transmit beams belonging to the same cell into the same group. Of course, this disclosure does not limit the principle of division.

[0118] Furthermore, according to embodiments of this disclosure, the activation unit 220 can determine which of the multiple TCI states configured by the activation configuration unit 210 are among them. Furthermore, the activation unit 220 can generate activation information and send the activation information to the user equipment via the communication unit 240 to activate the multiple TCI states, each TCI state including one or more TCI states, preferably including multiple TCI states.

[0119] According to embodiments of this disclosure, the activation information generated by the activation unit 220 may include group identification information (also referred to as TCI codepoint index) for each activated TCI state and identification information for each TCI state included in each TCI state.

[0120] According to embodiments of this disclosure, the activation information may further include the identification information of the cell to which each set of TCI states is applied, i.e., a set of TCI states is set for that cell, although this set of TCI states may come from different cells.

[0121] Figure 10 This is a schematic diagram illustrating the activated TCI state for PDSCH according to another embodiment of this disclosure. Figure 10 In this context, PCI represents the Physical Cell Identifier (PCI) of the cell to which this set of TCI states applies. This means a set of TCI states is set for cells with this PCI identifier, and these TCI states may originate from different cells. R indicates a reserved bit. BWP ID represents the identifier of the BWP (Band Width Part) used by the cell with this PCI identifier. (TCI State ID) i,j This represents the identifier of the j-th TCI state in group i. i,j This indicates whether there exists a TCI state j in group i, when C i,j A value of 0 indicates that there is no TCI state j in group i. When C i,j A value of 1 indicates the existence of the j-th TCI state in group i. i represents the group identifier, ranging from 0 to N, meaning there are N+1 groups of TCI states. j represents the TCI state number within the group, ranging from 1 to K, meaning each group contains at most K TCI states. Preferably, K can be 2 or 4.

[0122] like Figure 10 As shown, in group number 0, the TCI status ID 0,1 This indicates the identifier for the first TCI state in group number 0. 0,2 This indicates whether there exists a second TCI state in group number 0, i.e., the TCI state ID. 0,2 Does this domain exist? When C... 0,2 When it is 1, TCI status ID0,2 This indicates the identifier for the second TCI state in group number 0. 0,3 This indicates whether there exists a third TCI state in group number 0, i.e., the TCI state ID. 0,3 Does this domain exist? And so on, when C... 0,K When it is 1, TCI status ID 0,K This represents the identifier of the Kth TCI state in group number 0. Similarly, in group number N, the TCI state ID... N,1 This indicates the identifier of the first TCI state in group N. N,2 This indicates whether there exists a second TCI state in group N, i.e., the TCI state ID. N,2 Does this domain exist? When C... N,2 When it is 1, TCI status ID N,2 This indicates the identifier for the second TCI state in group N. N,3 This indicates whether there exists a 3rd TCI state in group N, i.e., the TCI state ID. N,3 Does this domain exist? And so on, when C...

[0123] According to embodiments of this disclosure, the activation information may further include the identification information of the serving cell of the user equipment, that is, multiple sets of TCI states are set for the serving cell, although these multiple sets of TCI states may come from different cells.

[0124] Figure 11 This is a schematic diagram illustrating the activated TCI state for PDSCH according to another embodiment of the present disclosure. Figure 11 and Figure 10 The examples shown are similar, and the same parts will not be repeated. Figure 11 and Figure 10 The difference lies in Figure 11 In the example shown, the serving cell ID is included in the TCI state group numbered 0, ... and the serving cell ID is also included in the TCI state group numbered N.

[0125] As described above, the user equipment can activate multiple TCI states through the activation information generated by the activation unit 220, and each TCI state includes one or more TCI states.

[0126] Dynamic indication of TCI status

[0127] According to an embodiment of this disclosure, the indication unit 230 can determine which set of TCI states corresponds to the transmit beam that will transmit the PDSCH, thereby generating indication information to indicate one set of TCI states among multiple sets of TCI states.

[0128] According to embodiments of this disclosure, the indication information may include group identification information for a set of TCI states. For example, when the indication information includes group identifier 0, the user equipment may determine that the electronic device 200 dynamically indicates group number 0, thereby the user equipment may determine which TCI states are included in group number 0 for the dynamically indicated TCI states.

[0129] As described above, according to embodiments of this disclosure, for a PDSCH, TCI states corresponding to transmit beams from multiple cells can be configured, thereby reducing the frequency of TCI state configuration for user equipment. Furthermore, TCI states can be divided into multiple groups and multiple groups of TCI states can be activated. Indication information is sent to the user equipment to indicate a group of TCI states, enabling the user equipment to determine multiple transmit beams corresponding to the TCI states included in that group, and to determine multiple receive beams to receive the PDSCH. Since these multiple transmit beams transmit the same content, the accuracy of the signal received by the user equipment can be improved.

[0134] According to embodiments of this disclosure, the electronic device 200 can divide the multiple TCI states configured by the configuration unit 210 into multiple groups, each group including one or more TCI states, preferably multiple TCI states. The number of TCI states included in each group may be the same or different.

[0135] Furthermore, according to embodiments of this disclosure, the activation unit 220 can determine one of the multiple sets of TCI states configured by the activation configuration unit 210 for each CORESET. Furthermore, the activation unit 220 can generate activation information and send the activation information to the user equipment via the communication unit 240 to activate a set of TCI states, which includes one or more TCI states.

[0136] According to embodiments of this disclosure, the activation information generated by the activation unit 220 may include the identification information of each TCI state in a set of activated TCI states.

[0137] According to embodiments of this disclosure, the activation information may further include the identification information of the cell to which the set of TCI states applies, i.e., a set of TCI states is set for the cell, although this set of TCI states may come from different cells.

[0138] Figure 12 This is a schematic diagram illustrating the activated TCI state for the PDCCH according to another embodiment of the present disclosure. Figure 12 In this context, PCI represents the physical cell identifier of the cell to which this set of TCI states applies. That is, a set of TCI states is set for the cell with this PCI identifier, and this set of TCI states may come from different cells. R indicates a reserved bit. CORESET ID represents the identifier of the control resource set to which this set of TCI states applies, and BWP ID represents the identifier of the BWP used by the cell with this PCI identifier. TCI State ID i,j This represents the identifier of the j-th TCI state in group i. i,j This indicates whether there exists a TCI state j in group i, when C i,j A value of 0 indicates that there is no TCI state j in group i. When C i,j A value of 1 indicates the existence of the j-th TCI state in group i. i represents the group identifier information of the group where the activated TCI state is located. j represents the TCI state number within the group, ranging from 1 to K, meaning the group contains at most K TCI states. Preferably, K can be 1, 2, or 4.

[0139] like Figure 12 As shown, activation unit 220 activated group number 0, TCI status ID 0,1 This indicates the identifier for the first TCI state in group number 0. 0,2 This indicates whether there exists a second TCI state in group number 0, i.e., the TCI state ID. 0,2 Does this domain exist? When C... 0,2 When it is 1, TCI status ID 0,2 This indicates the identifier for the second TCI state in group number 0. 0,3 This indicates whether there exists a third TCI state in group number 0, i.e., the TCI state ID. 0,3 Does this domain exist? And so on, when C... 0,K When it is 1, TCI status ID 0,K This indicates the identifier of the Kth TCI state in group number 0.

[0140] According to embodiments of this disclosure, the activation information may further include the identification information of the serving cell of the user equipment, that is, a set of TCI states is set for the serving cell, although this set of TCI states may come from different cells.

[0141] Figure 13 This is a schematic diagram illustrating the activated TCI state for the PDCCH according to another embodiment of the present disclosure. Figure 13 and Figure 12 The examples shown are similar, and the same parts will not be repeated. Figure 13 and Figure 12 The difference lies in Figure 13 In the example shown, the selected TCI status group includes the serving cell ID instead of the PCI.

[0142] As described above, the user equipment can activate a set of TCI states through the activation information generated by the activation unit 220. The set of TCI states includes one or more TCI states, preferably multiple TCI states.

[0143] As described above, according to embodiments of this disclosure, for the PDCCH, TCI states corresponding to transmit beams from multiple cells can be configured, thereby reducing the frequency of TCI state configuration for the user equipment. Furthermore, the TCI states can be divided into multiple groups, and one group of TCI states can be activated, allowing the user equipment to determine multiple transmit beams corresponding to the TCI states included in that group, and to determine multiple receive beams to receive the PDCCH. Since these multiple transmit beams transmit the same content, the accuracy of the signal received by the user equipment can be improved.

[0144] According to embodiments of this disclosure, the electronic device 200 can dynamically indicate multiple transmit beams to be transmitted for PDSCH at once through indication information, or activate multiple transmit beams to be transmitted for PDCCH at once through activation information, so that the user equipment can determine multiple receive beams based on multiple transmit beams, thereby realizing the SFN communication mode.

[0145] According to embodiments of this disclosure, electronic device 200 can receive reception capability information of user equipment from user equipment via communication unit 240. Here, the reception capability information of user equipment may include whether the user equipment can simultaneously use multiple receiving beams to receive information, and optionally may also include the maximum number of receiving beams that the user equipment can use simultaneously. Thus, electronic device 200 can determine the reception capability of user equipment, and thereby determine the number of active or dynamically indicated TCI states based on the reception capability of user equipment.

[0146] In summary, the configuration, activation, and dynamic indication process of TCI status can be optimized according to the embodiments of this disclosure.

[0147] <3. User Equipment Configuration Example>

[0157] As described above, the electronic device 1400 according to this disclosure can configure the TCI states of multiple cells, thereby avoiding frequent configuration of the TCI states. Furthermore, indication or activation information can indicate or activate multiple TCI states, thereby determining multiple transmit beams corresponding to the multiple TCI states, and thus determining multiple receive beams. Since the electronic device 1400 can use multiple receive beams to receive the same content, the accuracy of reception can be improved. In summary, embodiments according to this disclosure can optimize the TCI state configuration, activation, and dynamic indication process.

[0162] TCI status configuration

[0163] According to embodiments of this disclosure, electronic device 1400 can receive configuration information from network-side equipment, thereby enabling configuration unit 1410 to configure TCI states associated with multiple transmit beams from different cells. Here, the configuration information may include information about multiple TCI states, and the information for each TCI state may include an identifier of the TCI state, an identifier of the reference signal to which the TCI state corresponds, and an identifier of the cell to which the transmit beam corresponding to the TCI state belongs.

[0165] According to embodiments of this disclosure, activation unit 1420 can receive activation information from network-side devices, thereby determining the active TCI states among the multiple TCI states configured by configuration unit 1410 based on the activation information. For example, electronic device 1400 can activate the TCI state corresponding to the transmit beam of the cell about to pass through based on the activation information.

[0166] Dynamic indication of TCI status

[0167] According to embodiments of this disclosure, the indication information may include information for identifying a specific TCI state among a plurality of TCI states. Further, the indication unit 1430 may determine the specific TCI state and the TCI states associated with the specific TCI state as two or more TCI states to be indicated.

[0168] According to embodiments of this disclosure, the TCI states associated with a specific TCI state may include TCI states that are a predetermined number of times away from the specific TCI state. That is, the TCI states associated with a specific TCI state may include a predetermined number of TCI states before the specific TCI state and a predetermined number of TCI states after the specific TCI state.

[0169] According to embodiments of this disclosure, the predetermined number can be 1. That is, the TCI states associated with a particular TCI state include the TCI states adjacent to the particular TCI state, namely the TCI states immediately preceding and immediately following the particular TCI state.

[0170] According to embodiments of this disclosure, after the indication unit 1430 determines a specific TCI state based on the indication information, it can determine the TCI states associated with the specific TCI state. For example, after the indication unit 1430 determines that the specific TCI state is TCI state 4, assuming a predetermined number of 2, the indication unit 1430 can determine that the TCI states associated with the specific TCI state are TCI state 2, TCI state 3, TCI state 5, and TCI state 6, thereby determining TCI states 2-TCI state 6 as the TCI states dynamically indicated by the network-side device.

[0171] According to embodiments of this disclosure, the information used to identify a specific TCI state may include identification information for that specific TCI state. The indication unit 1430 can determine the specific TCI state based on the identification information for that specific TCI state.

[0172] According to embodiments of this disclosure, the information used to identify a specific TCI state may include a difference value between the identification information of the specific TCI state included in the current indication information and the identification information of the specific TCI state included in the previous indication information. The indication unit 1430 can determine the identification information of the specific TCI state included in the current indication information based on this difference value and the identification information of the specific TCI state included in the previous indication information. For example, the indication unit 1430 can determine the identification information of the specific TCI state included in the current indication information by adding the difference value to the identification information of the specific TCI state included in the previous indication information. If the value after the addition operation overflows the maximum number of configured TCI states, the cyclic shift count starts from 0.

Furthermore, the indication information can indicate multiple TCI states, and the determining unit 1440 can determine multiple transmit beams corresponding to the indicated multiple TCI states, thereby determining multiple receive beams to receive the PDSCH. Since the electronic device 1400 can use multiple receive beams to receive the same content, the accuracy of reception can be improved.

[0175] TCI status configuration

[0176] The configuration of the TCI state for PDCCH according to the embodiments of this disclosure is the same as the configuration of the TCI state for PDSCH, and will not be repeated here.

[0177] Activation of TCI state

[0178] According to embodiments of this disclosure, the activation information may include information for identifying a specific TCI state among a plurality of TCI states. Further, the activation unit 1420 may determine the specific TCI state and the TCI states associated with the specific TCI state as two or more activated TCI states.

[0179] According to embodiments of this disclosure, the TCI states associated with a specific TCI state may include TCI states that are a predetermined number of times away from the specific TCI state. That is, the TCI states associated with a specific TCI state may include a predetermined number of TCI states before the specific TCI state and a predetermined number of TCI states after the specific TCI state.

[0180] According to embodiments of this disclosure, the predetermined number can be 1. That is, the TCI states associated with a particular TCI state include the TCI states adjacent to the particular TCI state, namely the TCI states immediately preceding and immediately following the particular TCI state.

[0181] According to embodiments of this disclosure, after the activation unit 1420 determines a specific TCI state based on the activation information, it can determine the TCI states associated with the specific TCI state. For example, after the activation unit 1420 determines that the specific TCI state is TCI state 4, assuming a predetermined number of 2, the activation unit 1420 can determine that the TCI states associated with the specific TCI state are TCI state 2, TCI state 3, TCI state 5, and TCI state 6, thereby determining TCI states 2-TCI state 6 as the TCI states activated by the network-side device.

[0182] According to embodiments of this disclosure, the information used to identify a specific TCI state may include identification information for that specific TCI state. The activation unit 1420 can determine the specific TCI state based on the identification information.

[0183] According to embodiments of this disclosure, the information used to identify a specific TCI state may include a difference value between the identification information of the specific TCI state included in the current activation information and the identification information of the specific TCI state included in the previous activation information. The activation unit 1420 can determine the identification information of the specific TCI state included in the current activation information based on the difference value and the identification information of the specific TCI state included in the previous activation information. For example, the activation unit 1420 can use the difference value plus the identification information of the specific TCI state included in the previous activation information to determine the identification information of the specific TCI state included in the current activation information. If the maximum number of configured TCI states is exceeded, the cyclic shift count starts from 0.

[0184] As described above, the electronic device 1400 according to this disclosure can configure the TCI states of multiple cells, thereby avoiding frequent configuration of the TCI states. Furthermore, the activation unit 1420 can determine multiple active TCI states, and the determination unit 1440 can determine multiple transmit beams corresponding to the multiple active TCI states, thereby determining multiple receive beams to receive the PDCCH. Since the electronic device 1400 can use multiple receive beams to receive the same content, the accuracy of reception can be improved.

[0191] According to embodiments of this disclosure, the activation information includes group identifier information for each group of TCI states in a plurality of TCI states and identifier information for each TCI state included in each group of TCI states.

[0192] According to embodiments of this disclosure, the activation information may further include the identification information of the cell to which each set of TCI states is applied, i.e., a set of TCI states is set for that cell, although this set of TCI states may come from different cells.

[0193] According to embodiments of this disclosure, the activation information may also include the identification information of the serving cell of the electronic device 1400, i.e., multiple sets of TCI states are set for the serving cell, although these multiple sets of TCI states may come from different cells.

[0196] According to embodiments of this disclosure, the indication information may include group identification information indicating a set of TCI states.

[0197] As described above, the electronic device 1400 according to this disclosure can configure the TCI states of multiple cells, thereby avoiding frequent configuration of TCI states. Furthermore, the activation unit 1420 can determine multiple active TCI states, and the indication unit 1430 can determine an indicated TCI state. The determination unit 1440 can determine multiple transmit beams corresponding to the multiple TCI states included in the indicated TCI state, thereby determining multiple receive beams to receive the PDSCH.

Furthermore, user equipment can be a wireless communication module (such as an integrated circuit module comprising a single chip) installed in each of the aforementioned user equipments.

[0244] <Application Examples of Base Stations>

[0245] (First application example)

[0246] Figure 17 This is a block diagram illustrating a first example of a schematic configuration of an eNB to which the technologies of this disclosure can be applied. The eNB 1700 includes one or more antennas 1710 and a base station device 1720. The base station device 1720 and each antenna 1710 can be connected to each other via RF cables.

[0247] Each of the antennas 1710 includes one or more antenna elements (such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna) and is used by the base station equipment 1720 to transmit and receive wireless signals. Figure 17 As shown, the eNB 1700 may include multiple antennas 1710. For example, the multiple antennas 1710 may be compatible with multiple frequency bands used by the eNB 1700. Although Figure 17An example is shown in which the eNB 1700 includes multiple antennas 1710, but the eNB 1700 may also include a single antenna 1710.

[0248] The base station equipment 1720 includes a controller 1721, a memory 1722, a network interface 1723, and a wireless communication interface 1725.

[0249] The controller 1721 can be, for example, a CPU or a DSP, and operates various higher-level functions of the base station equipment 1720. For example, the controller 1721 generates data packets based on data in signals processed by the wireless communication interface 1725, and transmits the generated packets via the network interface 1723. The controller 1721 can bundle data from multiple baseband processors to generate bundled packets and transmit the generated bundled packets. The controller 1721 may have logical functions that perform controls such as radio resource control, radio bearer control, mobility management, admission control, and scheduling. This control can be performed in conjunction with nearby eNBs or core network nodes. The memory 1722 includes RAM and ROM, and stores programs executed by the controller 1721 and various types of control data (such as terminal lists, transmission power data, and scheduling data).

[0250] Network interface 1723 is a communication interface for connecting base station equipment 1720 to core network 1724.

Instead of controller 1721, BB processor 1726 may have some or all of the above-described logical functions. BB processor 1726 may be a memory storing communication control programs, or a module including a processor and associated circuitry configured to execute programs. Update programs can change the functionality of BB processor 1726. The module may be a card or blade inserted into a slot in base station equipment 1720. Alternatively, the module may be a chip mounted on a card or blade. Meanwhile, the RF circuit 1727 may include, for example, a mixer, a filter, and an amplifier, and transmits and receives wireless signals via the antenna 1710.

[0252] like Figure 17 As shown, the wireless communication interface 1725 may include multiple BB processors 1726. For example, the multiple BB processors 1726 may be compatible with multiple frequency bands used by the eNB 1700. Figure 17 As shown, the wireless communication interface 1725 may include multiple RF circuits 1727. For example, the multiple RF circuits 1727 may be compatible with multiple antenna elements. Although Figure 17 An example is shown in which the wireless communication interface 1725 includes multiple BB processors 1726 and multiple RF circuits 1727, but the wireless communication interface 1725 may also include a single BB processor 1726 or a single RF circuit 1727.
