[0003] In 5G New Radio (NR) systems, especially in communication frequency bands above 6 GHz, beam-based transmission and reception are required to ensure coverage due to the rapid attenuation of high-frequency channels.

[0004] When a base station has multiple Transmitter Receiver Points (TRPs), each TRP has one or more transmit antenna panels, or when a base station has only one TRP with multiple transmit panels, the base station can use multiple panels to simultaneously transmit data to the same User Equipment (UE). These multiple panels can originate from the same TRP or different TRPs. Similarly, when a terminal also has multiple panels, the terminal can use multiple panels to transmit data to the base station. However, when the terminal needs to perform a handover, communication is prone to interruption during the handover process, thus affecting the quality of service for data transmission.

[0132] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: a number of terminals 11 and a number of base stations 12.

[0133] Terminal 11 can be a device that provides voice and / or data connectivity to a user. Terminal 11 can communicate with one or more core networks via a Radio Access Network (RAN). Terminal 11 can be an Internet of Things (IoT) terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, terminal 11 can also be a device on an unmanned aerial vehicle (UAV). Alternatively, terminal 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, terminal 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0134] Base station 12 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, it can be a next-generation system after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network) or a Machine-Type Communication (MTC) system.

[0135] In this embodiment, base station 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, base station 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When base station 12 adopts a centralized-distributed architecture, it typically includes a Central Unit (CU) and at least two Distributed Units (DUs). The Central Unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the Distributed Units are equipped with a Physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of base station 12.

[0136] Base station 12 and terminal 11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0138] In some embodiments, the wireless communication system described above may further include a network management device 13.

[0139] Several base stations 12 are connected to network management device 13. Network management device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 13 is not limited in this embodiment.

[0140] In NR systems, especially in communication bands above 6GHz, high-frequency channels attenuate rapidly. To ensure coverage, beam-based transmission and reception are required. Currently, the consideration is for both the base station and the UE to use a single panel for data transmission and reception.

[0141] When a base station has multiple Transmitter Receiver Points (TRPs), each TRP has one or more transmit antenna panels, or when a base station has only one TRP with multiple transmit panels, the base station can use multiple panels (which can come from the same TRP or different TRPs) to simultaneously transmit data to the same User Equipment (UE). Similarly, when a UE also has multiple panels, the UE can use multiple panels to transmit data to the base station. Therefore, when a UE needs to perform a handover, panel-based handover can be used. However, how to achieve seamless handover using multiple panels is a technical problem that urgently needs to be solved.

[0142] Based on the aforementioned wireless communication system, when a UE has multiple panels, this disclosure proposes various embodiments of the method to achieve seamless handover and ensure communication continuity during the handover process.

[0143] Figure 2 This is a flowchart illustrating a communication processing method according to an exemplary embodiment. Figure 1 ,like Figure 2 As shown, this communication processing method is applied in a user equipment (UE) and includes the following steps:

[0144] In step S11, the user equipment (UE) uses a first antenna panel to communicate with the serving cell and a second antenna panel to communicate with the target cell. The UE has at least a first antenna panel and a second antenna panel.

[0145] The technical solution described in this disclosure enables the UE to communicate with the serving cell and the target cell respectively by using different antenna panels, thereby achieving seamless handover, ensuring the continuity of communication during the handover process, reducing handover interruption time, and improving terminal throughput.

[0146] In some embodiments, communication with the target cell using the second antenna panel in the UE includes:

[0147] If the measurement result obtained by the second antenna panel indicates that the received signal of the target cell meets the first preset condition, then the second antenna panel is used to communicate with the target cell.

[0148] In some implementations, the first preset condition includes at least one of the following:

[0149] The difference between the Reference Signal Received Power (RSRP) of the target cell and the RSRP of the serving cell is higher than a first threshold; or

[0150] The difference between the Reference Signal Received Quality (RSRQ) of the target cell and the RSRQ of the serving cell is higher than a second threshold; or

[0151] The difference between the signal-to-interference-plus-noise ratio (SINR) of the target cell and the SINR of the serving cell is higher than the third threshold.

[0152] In other words, when the measurement result obtained by the UE using the second antenna panel shows that the received signal of the target cell is better than that of the serving cell, the UE uses the second antenna panel to communicate with the target cell.

[0153] For example, the target cell's RSRP is higher than the serving cell's RSRP by a first threshold, or the target cell's RSRQ is higher than the serving cell's RSRQ by a second threshold, or the target cell's SINR is higher than the serving cell's SINR by a third threshold, and the second antenna panel is used to communicate with the target cell.

[0154] It should be noted that the first threshold, the second threshold, and the third threshold can be set or adjusted according to actual conditions such as communication quality.

[0155] In other embodiments, the first preset condition includes at least one of the following:

[0156] The serving cell's RSRP is lower than a first reference value, and the target cell's RSRP is higher than a second reference value, wherein the second reference value is greater than or equal to the first reference value; or

[0157] The serving cell's RSRQ is lower than a third reference value, and the target cell's RSRQ is higher than a fourth reference value, wherein the fourth reference value is greater than or equal to the third reference value; or

[0158] The SINR of the serving cell is lower than the fifth reference value, and the SINR of the target cell is higher than the sixth reference value, wherein the sixth reference value is greater than or equal to the fifth reference value.

[0159] In other words, when the measurement result obtained by the UE using the second antenna panel shows that the received signal of the target cell is better, the UE uses the second antenna panel to communicate with the target cell.

[0160] It should be noted that the first reference value, the second reference value, the third reference value, the fourth reference value, the fifth reference value, and the sixth reference value can be set or adjusted according to actual conditions such as communication quality.

[0161] The RSRP, RSRQ, and SINR values ​​mentioned above can be L1 and / or L3 values. The L1 value is the instantaneous sampled value at the physical layer; the L3 value is the Radio Resource Management (RRM) measurement value obtained by averaging multiple physical layer sampled values ​​through a sliding window.

[0162] In some embodiments, communicating with the serving cell using a first antenna panel in the UE and communicating with the target cell using a second antenna panel in the UE includes:

[0163] Use the second antenna panel to perform random access with the target cell. Once the random access is successful, disconnect the first antenna panel from the serving cell.

[0164] Thus, during the random access process between the second antenna panel and the target cell, the terminal's first antenna panel continues to maintain communication with the serving cell. Only after the second antenna panel successfully establishes a random access with the target cell can it communicate normally with the target cell, at which point the first antenna panel will interrupt its communication with the serving cell. Therefore, the terminal maintains data communication with either the serving or target cell at least once, enabling seamless handover and ensuring communication continuity during the handover process.

[0165] In some embodiments, after disconnecting the first antenna panel from the serving cell, the method further includes:

[0166] Determine the timing advance (TA) for communication between the first antenna panel and the target cell;

[0167] The first antenna panel uses the TA to transmit data with the target cell.

[0168] Here, the data transmission mainly refers to the transmission of uplink data.

[0169] Thus, after the second antenna panel successfully connects to the target cell, the UE disconnects the first antenna panel from the serving cell. The first antenna panel then needs to switch to the target cell. Switching to the target cell requires obtaining a communication access key (TA) for the target cell, enabling data transmission. This allows the first antenna panel to successfully switch from the serving cell to the target cell, ensuring communication continuity during the handover process.

[0170] In some implementations, determining the communication TA between the first antenna panel and the target cell includes:

[0171] The communication access term (TA) between the first antenna panel and the target cell is determined by performing random access between the first antenna panel and the target cell.

[0172] Thus, by using random access to determine the communication TA between the first antenna panel and the target cell, the obtained TA value is more accurate.

[0173] In some implementations, determining the communication TA between the first antenna panel and the target cell includes:

[0174] The TA of the first antenna panel communicating with the target cell is determined based on the TA value of the second antenna panel communicating with the target cell.

[0175] For example, the TA value of the second antenna panel communicating with the target cell can be used as the TA value of the first antenna panel communicating with the target cell.

[0176] For example, based on the TA value of the second antenna panel communicating with the target cell, the TA of the first antenna panel communicating with the target cell is calculated according to a preset algorithm. It should be noted that this disclosure does not limit the preset algorithm. Any algorithm that can make the calculated value close to or equal to the TA value obtained through random access can be used as the preset algorithm.

[0177] In this way, the TA value of the second antenna panel communicating with the target cell is used to determine the TA value of the first antenna panel communicating with the target cell, which makes the acquisition of the TA value faster and reduces the handover time.

[0178] In some embodiments, communicating with the serving cell using a first antenna panel in the UE and communicating with the target cell using a second antenna panel in the UE includes:

[0179] After successfully connecting to the target cell using the second antenna panel, continue communicating with the serving cell using the first antenna panel while simultaneously communicating with the target cell using the second antenna panel, until the second preset condition is met, at which point the connection between the first antenna panel and the serving cell is disconnected.

[0180] This ensures that each antenna panel is connected to the best cell, guaranteeing the highest throughput.

[0181] In some implementations, the second preset condition includes at least one of the following:

[0182] The measurement result obtained using the first antenna panel indicates that the received signal of the target cell meets the first preset condition; or

[0183] After transmitting the data that needs to be retransmitted using the first antenna panel, the data that needs to be retransmitted refers to data that was transmitted once but failed to transmit before the second antenna panel disconnected from the serving cell; or

[0184] The first antenna panel is used to transmit the data that needs to be sent to the UE and has already been stored in the base station to which the serving cell belongs to the serving cell.

[0185] Here, the first preset condition is the same as the first preset condition mentioned above, and will not be repeated here. When the measurement result of the first antenna panel does not meet the first preset condition, it means that the channel conditions when the first antenna panel is communicating with the serving cell are better than the channel conditions when communicating with the target cell. Therefore, the first antenna panel continues to communicate with the serving cell, while the second antenna panel communicates with the target cell. In this way, each antenna panel communicates with the cell with the best channel conditions, so that the throughput provided by the network to the terminal can reach the maximum.

[0186] Here, "transmission complete" means the transmission was successful, or it failed but the maximum number of retransmissions was reached. The maximum number of retransmissions can be set or adjusted based on actual conditions such as communication quality or speed.

[0187] The data that needs to be retransmitted here is the data transmitted between the serving cell and the UE, including both the data transmitted between the first panel and the serving cell, and the data transmitted between the second panel and the serving cell. This data consists of data that was transmitted once but failed to be transmitted at a certain point in time, which is the moment when the second antenna panel and the serving cell lost connection.

[0188] In some embodiments, communicating with the serving cell using the first antenna panel while simultaneously communicating with the target cell using the second antenna panel includes:

[0189] Based on the Physical Downlink Control Channel (PDCCH) information sent by the serving cell or the target cell, the first antenna panel is used to communicate with the serving cell via Physical Downlink Shared Channel (PDSCH) or Physical Uplink Shared Channel (PUSCH), and the second antenna panel is used to communicate with the target cell via PDSCH or PUSCH.

[0190] The PDCCH information refers to the DCI information carried by the PDCCH.

[0191] In some implementations, scheduling information for indicating the PDSCH or PUSCH of the serving cell and scheduling information for indicating the PDSCH or PUSCH of the target cell are carried in the same PDCCH information.

[0192] In other words, PDCCH information is either sent by the serving cell or by the target cell.

[0193] In other embodiments, scheduling information for indicating the serving cell's PDSCH or PUSCH, and scheduling information for indicating the target cell's PDSCH or PUSCH, are carried in different PDCCH information.

[0194] Here, different PDCCHs can refer to: both being sent by the serving cell but not in the same PDCCH, or both being sent by the target cell but not in the same PDCCH; or they can refer to: the serving cell sending PDCCH information for scheduling the serving cell's PDSCH and PUSCH, while the target cell sending PDCCH information for scheduling the target cell's PDSCH and PUSCH.

[0195] In other words, only one cell sends a PDCCH to schedule the final UE to use two antenna panels to communicate with the two cells via PDSCH or PUSCH. Different PDCCHs can be used to schedule PDSCH or PUSCH with the two cells respectively, or the same PDCCH can be used to schedule PDSCH or PUSCH with the two cells. That is, the same PDCCH can only schedule the UE to communicate with one cell, or the same PDCCH can schedule the UE to communicate with two cells. In some embodiments, communicating with the serving cell using the first antenna panel while simultaneously communicating with the target cell using the second antenna panel includes:

[0196] Based on the PDCCH information sent by the serving cell and the target cell, the first antenna panel is used to communicate with the serving cell via PDSCH or PUSCH, and the second antenna panel is used to communicate with the target cell via PDSCH or PUSCH.

[0197] The serving cell and the target cell send the same PDCCH information; the PDCCH information carries scheduling information for indicating the PDSCH or PUSCH of the serving cell, and / or scheduling information for indicating the PDSCH or PUSCH of the target cell.

[0198] In other words, both the serving cell and the target cell send PDCCHs, and they send the same PDCCH. Furthermore, the same PDCCH can schedule the UE to communicate with only one cell, or the same PDCCH can schedule the UE to communicate with two cells.

[0199] In some embodiments, communicating with the serving cell using the first antenna panel while simultaneously communicating with the target cell using the second antenna panel includes:

[0200] Based on the first PDCCH information sent by the serving cell, the first antenna panel is used to communicate with the serving cell via PDSCH or PUSCH.

[0201] Based on the second PDCCH information sent by the target cell, the second antenna panel is used to communicate with the target cell via PDSCH or PUSCH.

[0202] Here, the first PDCCH information and the second PDCCH information are different PDCCH information.

[0203] In other words, the serving cell and the target cell send PDCCHs separately, and send different PDCCHs, that is, each schedules the UE to communicate with its own cell.

[0204] The technical solution described in this disclosure enables the UE to communicate with the serving cell and the target cell respectively by using different antenna panels, thereby achieving seamless handover, ensuring the continuity of communication during the handover process; it can also reduce handover interruption time, improve terminal throughput and user experience.

[0206] In step S21, communication is established with the first antenna panel in the user equipment (UE).

[0207] In some embodiments, communicating with a first antenna panel in the UE includes:

[0208] Send PDCCH information to the UE; wherein, the same PDCCH information carries scheduling information for indicating the PDSCH or PUSCH of the serving cell, and scheduling information for indicating the PDSCH or PUSCH of the target cell.

[0209] In some embodiments, communicating with a first antenna panel in the UE includes:

[0210] Send PDCCH information to the UE; wherein, in different PDCCH information, scheduling information for indicating the serving cell's PDSCH or PUSCH and scheduling information for indicating the target cell's PDSCH or PUSCH are respectively carried.

[0211] In some embodiments, communicating with a first antenna panel in the UE includes:

[0212] Send a first PDCCH message to the UE, wherein the first PDCCH message carries scheduling information for indicating the PDSCH or PUSCH of the serving cell.

[0213] The technical solutions described in this disclosure enable the UE to communicate with the serving cell and the target cell respectively by using different antenna panels, thereby achieving seamless handover and ensuring the continuity of communication during the handover process.

[0214] Figure 4 This is a flowchart illustrating a communication processing method according to an exemplary embodiment. Figure 3 ,like Figure 4 As shown, this communication processing method is used in a target base station and includes the following steps:

[0215] In step S31, communication is established with the second antenna panel in the user equipment (UE).

[0216] In some embodiments, communicating with the second antenna panel in the UE includes:

[0217] Send PDCCH information to the UE; wherein, the same PDCCH information carries scheduling information for indicating the PDSCH or PUSCH of the serving cell, and scheduling information for indicating the PDSCH or PUSCH of the target cell.

[0218] In some embodiments, communicating with the second antenna panel in the UE includes:

[0219] Send PDCCH information to the UE; wherein, in different PDCCH information, scheduling information for indicating the serving cell's PDSCH or PUSCH and scheduling information for indicating the target cell's PDSCH or PUSCH are respectively carried.

[0220] In some embodiments, communicating with the second antenna panel in the UE includes:

[0221] Send a second PDCCH message to the UE, wherein the first PDCCH message carries scheduling information for indicating the PDSCH or PUSCH of the target cell.

[0222] The technical solutions described in this disclosure enable the UE to communicate with the serving cell and the target cell respectively by using different antenna panels, thereby achieving seamless handover and ensuring the continuity of communication during the handover process.

[0223] Figure 5 This is a communication processing device block illustrated according to an exemplary embodiment. Figure 1The communication processing device is applied to the UE side, wherein the UE has at least a first antenna panel and a second antenna panel, as shown in the reference. Figure 5 The device includes a first control unit 10 and a second control unit 20; wherein,

[0224] The first control unit 10 is configured to communicate with the serving cell using the first antenna panel;

[0225] The second control unit 20 is configured to communicate with the target cell using the second antenna panel.

[0226] The communication processing apparatus described in this disclosure enables the UE to communicate with the serving cell and the target cell respectively by using different antenna panels, thereby achieving seamless handover, ensuring the continuity of communication during the handover process, and improving terminal throughput.

[0227] In some embodiments, the second control unit 20 is configured to:

[0228] If the measurement result obtained by the second antenna panel indicates that the received signal of the target cell meets the first preset condition, then the second antenna panel is used to communicate with the target cell.

[0229] In some implementations, the first preset condition may include at least one of the following:

[0230] The difference between the RSRP of the target cell and the RSRP of the serving cell is higher than a first threshold; or

[0231] The difference between the RSRQ of the target cell and the RSRQ of the serving cell is higher than the second threshold; or

[0232] The difference between the SINR of the target cell and the SINR of the serving cell is higher than the third threshold.

[0233] In other words, when the measurement result obtained by the UE using the second antenna panel shows that the received signal of the target cell is better than that of the serving cell, the UE uses the second antenna panel to communicate with the target cell.

[0234] In other embodiments, the first preset condition may include at least one of the following:

[0235] The serving cell's RSRP is lower than a first reference value, and the target cell's RSRP is higher than a second reference value, wherein the second reference value is greater than or equal to the first reference value; or

[0236] The serving cell's RSRQ is lower than a third reference value, and the target cell's RSRQ is higher than a fourth reference value, wherein the fourth reference value is greater than or equal to the third reference value; or

[0237] The SINR of the serving cell is lower than the fifth reference value, and the SINR of the target cell is higher than the sixth reference value, wherein the sixth reference value is greater than or equal to the fifth reference value.

[0238] In other words, when the measurement result obtained by the UE using the second antenna panel shows that the received signal of the target cell is better, the UE uses the second antenna panel to communicate with the target cell.

[0239] RSRP, RSRQ, and SINR can be the values ​​of L1 and / or L3. The L1 value is the instantaneous sampled value of the physical layer; the L3 value is the RRM measurement value after averaging multiple physical layer sampled values ​​through a sliding window.

[0240] In some embodiments, the second control unit 20 is configured to: use the second antenna panel to perform random access with the target cell; the first control unit 20 is configured to: disconnect the connection between the first antenna panel and the serving cell after the second antenna panel has performed random access with the target cell.

[0241] In the communication processing apparatus described in this embodiment, during the random access process between the second antenna panel and the target cell, the terminal's first antenna panel continues to maintain communication with the serving cell. Only after the second antenna panel successfully accesses the target cell can it communicate normally with the target cell, and only then will the first antenna panel interrupt its communication with the serving cell. Therefore, the terminal has at least one antenna panel maintaining data communication with either the serving cell or the target cell, thereby enabling seamless handover and ensuring the continuity of communication during the handover process.

[0242] In the above scheme, the first control unit 20 is further configured to: after disconnecting the connection between the first antenna panel and the serving cell, determine the timing advance (TA) for communication between the first antenna panel and the target cell; and control the first antenna panel to use the TA to transmit data with the target cell.

[0243] In the communication processing apparatus described in this embodiment, after the second antenna panel successfully connects to the target cell, the UE disconnects the first antenna panel from the serving cell. Then, the first antenna panel also needs to switch to the target cell. The first antenna panel needs to obtain a TA (Transmission Acquisition Message) to communicate with the target cell in order to use the obtained TA to transmit data with the target cell. This enables the first antenna panel to switch from the serving cell to the target cell, ensuring that both the first and second antenna panels successfully switch to the target cell and guaranteeing the continuity of communication during the handover process.

[0244] In the above scheme, the first control unit 20 is configured as follows:

[0245] The communication access term (TA) between the first antenna panel and the target cell is determined by random access between the first antenna panel and the target cell; or

[0246] The TA of the first antenna panel communicating with the target cell is determined based on the TA value of the second antenna panel communicating with the target cell.

[0247] In some embodiments, the first control unit 10 is configured to: after successfully accessing the target cell using the second antenna panel, continue to communicate with the serving cell using the first antenna panel until a second preset condition is met, and then disconnect the connection between the first antenna panel and the serving cell; the second control unit 20 is configured to: after successfully accessing the target cell using the second antenna panel, communicate with the target cell using the second antenna panel.

[0248] The communication processing apparatus described in this embodiment can ensure that each antenna panel is connected to the best cell, thereby guaranteeing the highest throughput.

[0249] In the above scheme, the second preset condition includes at least one of the following situations:

[0250] The measurement result obtained using the first antenna panel indicates that the received signal of the target cell meets the first preset condition; or

[0251] After transmitting the data that needs to be retransmitted using the first antenna panel, the data that needs to be retransmitted refers to data that was transmitted once but failed to transmit before the second antenna panel disconnected from the serving cell; or

[0252] The first antenna panel is used to transmit the data that needs to be sent to the UE and has been stored in the base station to which the serving cell belongs to the serving cell.

[0253] Here, the first preset condition is the same as the first preset condition mentioned above, and will not be repeated here. When the measurement result of the first antenna panel does not meet the first preset condition, it means that the channel conditions when the first antenna panel is communicating with the serving cell are better than the channel conditions when communicating with the target cell. Therefore, the first antenna panel continues to communicate with the serving cell, while the second antenna panel communicates with the target cell. In this way, each antenna panel communicates with the cell with the best channel conditions, so that the throughput provided by the network to the terminal can reach the maximum.

[0254] Here, "transmission complete" means the transmission was successful, or it failed but the maximum number of retransmissions was reached. The maximum number of retransmissions can be set or adjusted based on actual conditions such as communication quality or speed.

[0255] The data that needs to be retransmitted here is the data transmitted between the serving cell and the UE, including both the data transmitted between the first panel and the serving cell, and the data transmitted between the second panel and the serving cell. This data consists of data that was transmitted once but failed to be transmitted at a certain point in time, which is the moment when the second antenna panel and the serving cell lost connection.

[0256] In some embodiments, the first control unit 10 is configured to: communicate with the serving cell via PDSCH or PUSCH using the first antenna panel based on PDCCH information sent by the serving cell or the target cell; the second control unit 20 is configured to: communicate with the target cell via PDSCH or PUSCH using the second antenna panel.

[0257] In some implementations, scheduling information for indicating the PDSCH or PUSCH of the serving cell and scheduling information for indicating the PDSCH or PUSCH of the target cell are carried in the same PDCCH information.

[0258] In some implementations, scheduling information for indicating the PDSCH or PUSCH of the serving cell and scheduling information for indicating the PDSCH or PUSCH of the target cell are carried in different PDCCH information.

[0259] In some embodiments, the first control unit 10 is configured to: communicate with the serving cell via PDSCH or PUSCH using the first antenna panel based on the PDCCH information sent by the serving cell and the target cell; the second control unit 20 is configured to: communicate with the target cell via PDSCH or PUSCH using the second antenna panel.

[0260] The serving cell and the target cell send the same PDCCH information; the PDCCH information carries scheduling information for indicating the PDSCH or PUSCH of the serving cell, and / or scheduling information for indicating the PDSCH or PUSCH of the target cell.

[0261] In some embodiments, the first control unit 10 is configured to: communicate with the serving cell via PDSCH or PUSCH using the first antenna panel based on the first PDCCH information sent by the serving cell; the second control unit 10 is configured to: communicate with the target cell via PDSCH or PUSCH using the second antenna panel based on the second PDCCH information sent by the target cell.

[0262] Regarding the apparatus in the above embodiments, the specific manner in which each module performs its operation has been described in detail in the embodiments related to the method, and will not be elaborated upon here.

[0263] In practical applications, the specific structures of the first control unit 10 and the second control unit 20 can be implemented by the communication processing device or the UE to which the communication processing device belongs, such as the central processing unit (CPU), microprocessor (MCU), digital signal processor (DSP), or programmable logic controller (PLC).
