Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a signal indication method, device, base station, and storage medium. Background Technology

[0002] In wireless communication systems, the coverage area of ​​each cell is fixed. When a User Equipment (UE) moves from the coverage area of ​​one cell to the coverage area of ​​another, a cell handover occurs. To achieve a zero-millisecond handover interruption time, the UE maintains a connection with the source cell throughout the handover process. After the UE connects to the target cell, it communicates with both the source and target cells simultaneously for a period of time. However, in some cases, the UE cannot simultaneously send uplink signals to both the source and target cells. In such cases, Time Division Multiplexing (TDM) is used, where the UE sends uplink signals to the source cell for a certain period and to the target cell for another period. However, if uplink signals are sent too early using TDM, the resource efficiency of the source cell will decrease, affecting the UE's data rate experience. If uplink signals are sent too late using TDM, there will be significant collisions in the uplink resources of the two cells, also leading to decreased resource efficiency and impacting the UE's data rate experience.

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other, and the terms "first," "second," "third," and "fourth" involved in the embodiments of this application are only used to distinguish different times, signals, information, cells, etc., and do not indicate a limitation on the order.

[0054] Furthermore, in the embodiments of this application, terms such as "optionally" or "exemplarily" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "optionally" or "exemplarily" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "optionally" or "exemplarily" is intended to present the relevant concepts in a specific manner.

[0055] To better understand the solutions provided in the embodiments of this application, further explanations and descriptions are provided regarding the relevant concepts that may be involved in the embodiments of this application, such as:

[0056] In wireless communication systems, there are two initial access methods for a UE: contention-based random access and non-contention-based random access. As shown in Figure 1, Figure 1(a) illustrates the contention-based random access procedure. Specifically, the UE sends a first message (e.g., Physical Random Access Channel (PRACH), or msg1) to the network side. The network side then sends a second message (e.g., Random Access Response (RAR), or msg2) back to the UE. The UE then sends a third message (e.g., msg3) to the network side, and the network side sends a fourth message (e.g., msg4) back to the UE. Once the UE receives and confirms the content of the fourth message, it indicates successful random access. Figure 1(b) illustrates the non-contention-based random access procedure. Specifically, the UE sends a first message (e.g., PRACH or msg1) to the network side. Upon receiving the first message, the network side identifies the UE and sends a second message (e.g., RAR) to the UE. Once the UE receives the second message, it indicates successful random access.

[0057] Time Division Multiplexing (TDM) Pattern: In wireless communication systems, the network configures a TDM pattern for the UE. The TDM pattern divides radio resources into three parts in the time domain: uplink, downlink, and a special area. When the UE uses the TDM pattern for communication, it only transmits or receives signals in one or more of the areas within the TDM pattern, and simultaneously receives or transmits according to the scheduling timing relationship corresponding to that TDM pattern. Table 1 shows the TDM pattern configuration, specifically the configuration within each radio frame (10ms in length). The unit indicated is a radio subframe, where D indicates that the subframe is the downlink portion of the TDM pattern, U indicates that the subframe is the uplink portion, and S indicates that the subframe is a special area. The UE communicates according to the TDM pattern configuration, meaning it only transmits on the uplink subframes configured in the TDM pattern, and simultaneously receives or transmits according to the scheduling timing relationship corresponding to the TDM pattern.

[0058] Table 1

[0059]

[0060] Based on the above concepts, Figure 2 One embodiment provides a signal indication method, which can be applied to a UE, such as... Figure 2 As shown, the method includes:

[0061] S201, The UE sends the first signal to the first cell.

[0062] Optionally, in this embodiment, the first cell can be the UE's source cell. The first signal can be used to instruct the first cell to communicate using a configured mode.

[0063] For example, the first signal mentioned above can be Physical Uplink Control Channel (PUCCH), PRACH, Sounding Reference Signal (SRS), Media Access Control Control Element (MAC CE), or Radio Resource Control (RRC) signaling.

[0064] Furthermore, the parameters of the first signal can be configured by the first cell. For example, it can configure time-domain resource location, time-domain resource size, time-domain resource period, frequency-domain resource location, frequency-domain resource size, sequence, Code Division Multiplexing Index (CDM index), cyclic shift, frequency hopping bandwidth, SRS index, PRACH index, transmission comb value, etc. The resources of the first signal can be periodic resources. Additionally, the first cell can configure a communication mode for the UE. For example, the first cell can configure a TDM pattern for the UE. Optionally, the first cell can also configure a Hybrid Automatic Repeat reQuest offset (HARQ offset) for the UE and use the TDM pattern for communication.

[0065] S202. The UE communicates with the first cell according to the first signal and the configured mode.

[0066] After the first cell configures the relevant resources, parameter information and communication mode of the first signal for the UE, the UE can communicate with the first cell through the configured mode according to the indication of the first signal.

[0067] This application provides a signal indication method in which a UE sends a first signal to a first cell. This first signal indicates the use of a configured mode for communication. Then, the UE communicates with the first cell using the configured mode based on the first signal. In this way, the UE and the first cell can communicate using the configured mode and corresponding resource timing scheduling indicated by the first signal, thereby improving resource utilization efficiency and the UE's speed experience.

[0068] In one example, in step S201, the UE sends a first signal to the first cell, which can be achieved in several optional ways:

[0069] Method 1: Before sending the first information to the second cell to which the UE accesses, the UE sends the first signal to the first cell;

[0070] Method 2: After sending the first information to the second cell to which the UE accesses, the UE sends the first signal to the first cell;

[0071] It should be noted that the above two methods can be used for the UE to send the first signal to the first cell when accessing the second cell in a contention-based random access mode or a non-contention-based random access mode.

[0072] Method 3: When the UE accesses the second cell in a non-contention-based manner, after receiving the second information sent by the second cell, the UE sends the first signal to the first cell.

[0073] Method 4: When the UE accesses the second cell in a contention-based manner, after receiving the fourth information sent by the second cell, the UE sends the first signal to the first cell.

[0074] The second cell mentioned above can be the target cell of the UE.

[0075] Furthermore, when the first signal transmitted by the UE is a PUCCH, the first signal resource configured by the first cell for the UE can be at least a specially configured PUCCH resource. That is, this PUCCH resource is different from other PUCCH resources used for Uplink Control Information (UCI) reporting; for example, at least one of the configuration parameters of the two PUCCHs is different. Optionally, when configuring the PUCCH resource, the first cell can simultaneously indicate that the PUCCH resource is used to indicate the use of the configured mode for communication. Optionally, the PUCCH can also be a short PUCCH (SPUCCH).

[0076] When the first signal transmitted by the UE is PRACH, the first signal resource configured by the first cell for the UE can be at least a specially configured PRACH resource, such as a preamble index. This means that the resource differs from other PRACH resources used for initial access; for example, at least one of the configuration parameters of the two PRACHs is different. Optionally, when configuring the PRACH resource, the first cell can simultaneously indicate that the PRACH resource is used to indicate the use of the configured mode for communication.

[0077] When the first signal transmitted by the UE is SRS, the first signal resource configured by the first cell for the UE can be at least a specially configured SRS resource, that is, this SRS resource is different from other SRS resources used for channel measurement. For example, at least one of the configuration parameters of the two SRSs is different. Optionally, when configuring the SRS resource, the first cell can simultaneously indicate that the SRS resource is used to indicate the use of the configured mode for communication.

[0078] Furthermore, the UE can communicate with the first cell through the configured mode based on the first signal. After sending the first signal, the UE can directly communicate with the first cell through the configured mode.

[0079] Alternatively, after the first time interval following the UE sending the first signal, it may communicate with the first cell using the configured mode.

[0080] Alternatively, the UE receives feedback information sent by the first cell in response to the first signal and communicates with the first cell through the configured mode. That is, after the UE sends the first signal, it receives feedback information sent by the first cell. When the UE receives feedback information sent by the first cell in response to the first signal, it communicates with the first cell through the configured mode.

[0081] Alternatively, after the UE receives the feedback information sent by the first cell for the first signal, after a first time interval, it communicates with the first cell through a configured mode. That is, after the UE sends the first signal, it receives the feedback information sent by the first cell. After the UE receives the feedback information sent by the first cell for the first signal, after a first time interval, it communicates with the first cell through a configured mode.

[0082] The specific length of the first time interval can be predetermined by the protocol or configured by the first cell. The length of the first time interval can be any of the following time lengths, for example, N time slots, or N subframes, or N radio frames, or N milliseconds, where N is an integer greater than 0.

[0083] It should be noted that when the UE communicates with the first cell through the configured mode after the first time interval following the transmission of the first signal or after the first time interval following the receipt of feedback information from the first cell regarding the first signal, the UE can directly adjust the communication mode after transmitting the first signal or after receiving feedback information from the first cell. For example, it can adopt the configured mode and then communicate with the first cell after the first time interval; or, the UE can adjust the communication mode to the configured mode after the first time interval and then communicate with the first cell through the configured mode.

[0084] After the UE and the first cell achieve communication through the above-mentioned optional methods, the UE and the first cell can communicate according to the configured communication mode based on the indication of the first signal. For example, the UE sends uplink signals according to the scheduling timing relationship of the TDM pattern, and similarly, the first cell performs resource scheduling according to the scheduling timing relationship of the TDM pattern based on the indication of the first signal.

[0085] Figure 3 One embodiment provides a signal indication method, which can be applied to a first cell, such as... Figure 3 As shown, the method includes:

[0086] S301, The first cell receives the first signal sent by the UE.

[0087] The first cell mentioned above can be the source cell of the UE, and the first signal can be used to instruct the first cell to use the configured mode for communication.

[0088] For example, the first signal received by the first cell can be PUCCH, PRACH, SRS, MAC CE, or RRC signaling.

[0089] Furthermore, the first cell can configure parameters of the first signal for the UE, such as time-domain resource location, time-domain resource size, time-domain resource period, frequency-domain resource location, frequency-domain resource size, sequence, CDM index, cyclic shift, frequency hopping bandwidth, SRS index, PRACH index, and transmission comb value, where the resources of the first signal can be periodic resources. Additionally, the first cell can configure a communication mode for the UE, for example, configuring a TDM pattern for the UE. Optionally, the first cell can configure a HARQ offset for the UE and can use the TDM pattern for communication.

[0090] S302. The first cell communicates with the UE through the configured mode based on the first signal.

[0091] After configuring the relevant resources, parameter information, and communication mode of the first signal for the UE, the first cell can communicate with the UE through the configured mode according to the indication of the received first signal.

[0092] This application provides a signal indication method. A first cell receives a first signal sent by a UE, wherein the first signal indicates that a configured mode should be used for communication. The first cell communicates with the UE according to the first signal and the configured mode. In this way, the first cell and the UE communicate using the configured mode and corresponding resource timing scheduling indicated by the first signal, thereby improving resource utilization efficiency and the UE's speed experience.

[0093] In one example, after the first cell receives the first signal sent by the UE, it can communicate with the UE through a configured mode. That is, after the first cell receives the first signal, it directly uses the configured mode to communicate with the UE.

[0094] In one example, after a first time interval following the first signal received by the first cell from the UE, the cell communicates with the UE using a configured mode. That is, after the first cell receives the first signal, after a first time interval, the cell communicates with the UE using a configured mode.

[0095] In one example, after the first cell sends feedback information in response to the received first signal, it communicates with the UE through a configured mode. That is, after the first cell receives the first signal sent by the UE and sends feedback information to the UE, it communicates with the UE through a configured mode.

[0096] In one example, after a first time interval following the first cell sending feedback information to the received first signal, the first cell communicates with the UE through a configured mode. That is, after the first cell receives the first signal sent by the UE and sends feedback information to the UE, after an interval of the first time interval, the first cell communicates with the UE through a configured mode.

[0097] The specific length of the first time interval can be predetermined by the protocol or configured by the first cell. The length of the first time interval can be any of the following time lengths, for example, N time slots, or N subframes, or N radio frames, or N milliseconds, where N is an integer greater than 0.

[0098] It should be noted that when the first cell communicates with the UE through the configured mode after a first time interval following the first time interval after receiving the first signal sent by the UE, or after a first time interval following the first time interval following the first time interval following the first time interval following the first time interval, the first cell may directly adjust the communication mode after receiving the first signal or after sending the feedback information for the first signal. For example, it may adjust the mode to the configured TDM pattern, and then communicate with the UE after the first time interval. Alternatively, the first cell may adjust the communication mode to the configured mode after the first time interval, and then communicate with the UE through the configured mode.

[0099] For example, such as Figure 4 As shown, the PUCCH configured by the first cell for the UE can be transmitted on subframes #1 and #7. This PUCCH is used by the UE to notify the first cell to use the TDM pattern for communication. If the UE uses the TDM pattern for communication after sending the first signal, that is, if the UE sends the PUCCH on subframe #1, then after subframe #1 (… Figure 4 After t1, the UE communicates with the first cell using the TDM pattern. Correspondingly, after receiving the PUCCH sent by the UE in subframe #1, the first cell, in subframe #1 (… Figure 4 After t1, the TDM pattern is used to communicate with the UE. If the UE uses the TDM pattern to communicate after a certain period of time following the uplink signal transmission, for example, if the UE transmits PUCCH in subframe #1 and the time interval is 3 subframes, then the UE will use the TDM pattern to communicate in subframe #4. Figure 4 After t2, the TDM pattern is used to communicate with the first cell. Correspondingly, after receiving the PUCCH sent by the UE in subframe #1, the first cell, after an interval of 3 subframes, communicates with the UE in subframe #4. Figure 4 After t2, TDM pattern is used to communicate with UE.

[0100] Similarly, if the first signal is PRACH or SRS, then the indication method of PRACH or SRS is the same as that of PUCCH, and will not be described in detail here.

[0101] like Figure 5As shown, if the first signal is MAC CE or RRC signaling, it indicates that TDM pattern should be used for communication. The UE sends a PUSCH in subframe #1, which carries MAC CE or RRC signaling indicating that TDM pattern should be used for communication. After receiving the PUSCH, the first cell sends corresponding feedback information in subframe #5 to confirm to the UE that the first cell has correctly received the PUSCH. After receiving the feedback information, the UE uses TDM pattern for communication, that is, the UE sends a PUSCH in subframe #5 (…). Figure 5 After t3, the TDM pattern is used to communicate with the first cell. Correspondingly, after the first cell sends feedback information confirming correct PUSCH reception in subframe #5, in subframe #5 ( Figure 5 After subframe #3, the UE communicates with the first cell using the TDM pattern. If the UE uses the TDM pattern to communicate after the first time interval following the feedback information received, and if the time interval is 3 subframes, then the UE uses the TDM pattern to communicate with the first cell after subframe #8 (3 subframes after subframe #5). Correspondingly, after sending the feedback information indicating that the PUSCH was correctly received in subframe #5, the first cell uses the TDM pattern to communicate with the UE after a 3-subframe interval, after subframe #8.

[0102] Figure 6 One embodiment provides a signal indication method, which can be applied to a UE, such as... Figure 6 As shown, the method includes:

[0103] S601, the UE receives the second signal sent by the first cell.

[0104] Optionally, in this embodiment, the first cell can be the UE's source cell. The second signal can be used to instruct the UE to communicate using a configured mode.

[0105] For example, the second signal mentioned above can be the Physical Downlink Control Channel (PDCCH), MAC CE, RRC signaling, or Channel State Information Reference Signal (CSI-RS).

[0106] Furthermore, the parameters of the second signal can be configured by the first cell, such as configuring time-domain resource location, time-domain resource size, time-domain resource period, frequency-domain resource location, frequency-domain resource size, sequence, CDM index, cyclic shift, etc., wherein the resources of the second signal can be periodic resources. Additionally, the first cell can configure a communication mode for the UE, for example, configuring a TDM pattern for the UE. Optionally, the first cell can configure a HARQ offset for the UE and use the TDM pattern for communication.

[0107] Furthermore, when the second signal received by the UE is a PDCCH, the second signal resource configured by the first cell for the UE can be at least a specially configured PDCCH resource. That is, this PDCCH resource is different from other PDCCH resources used for transmitting Downlink Control Information (DCI). For example, at least one of the configuration parameters of the two PDCCHs is different. Optionally, when configuring the PDCCH resource, the first cell can simultaneously indicate that the PDCCH resource is used to instruct the UE to use the configured mode for communication. Additionally, the PDCCH can also be a Short PDCCH (SPDCCH) or an Enhanced Physical Downlink Control Channel (EPDCCH).

[0108] When the second signal received by the UE is CSI-RS, the second signal resource configured by the first cell for the UE can be at least a specially configured CSI-RS resource, that is, this CSI-RS resource is different from other CSI-RS resources used for channel measurement. For example, at least one of the configuration parameters of the two CSI-RS resources is different. Optionally, when configuring the CSI-RS resource, the first cell can simultaneously indicate that the CSI-RS resource is used to instruct the UE to use the configured mode for communication.

[0109] S602, the UE communicates with the first cell according to the second signal and the configured mode.

[0110] After receiving the second signal sent by the first cell, the UE can communicate with the first cell according to the configured mode indicated by the second signal. For example, the UE can communicate according to the TDM pattern configured by the first cell according to the second signal, and send uplink signals according to the scheduling timing relationship of the TDM pattern. Similarly, the first cell can also perform resource scheduling according to the scheduling timing relationship of the TDM pattern.

[0111] In one example, after the UE sends feedback information to the first cell based on the second signal, it communicates with the first cell through a configured mode. That is, after the UE receives the second signal sent by the first cell, it sends feedback information to the first cell and then communicates with the first cell through the configured mode.

[0112] In one example, after the UE sends feedback information to the first cell based on the second signal, a second time interval is elapsed before the UE communicates with the first cell through a configured mode. That is, after the UE receives the second signal sent by the first cell, sends feedback information to the first cell, and after a second time interval, the UE communicates with the first cell through a configured mode.

[0113] In one example, after receiving the second signal, the UE communicates with the first cell through the configured mode. That is, after receiving the second signal sent by the first cell, the UE does not need to send feedback information to the second cell and can directly communicate with the first cell through the configured mode.

[0114] In one example, after the UE receives the second signal, a second time interval later, it communicates with the first cell through a configured mode. That is, after the UE receives the second signal sent by the first cell, it does not need to send feedback information to the second cell, and after a second time interval, it communicates with the first cell through a configured mode.

[0115] The specific length of the second time interval can be predetermined by the protocol or configured by the first cell. The length of the second time interval can be any one of the following time lengths, for example, N time slots, or N subframes, or N radio frames, or N milliseconds, where N is an integer greater than 0.

[0116] It should be noted that when the UE communicates with the first cell in the configured mode after the second time interval following the second time interval after sending feedback information to the first cell based on the second signal, or when the UE communicates with the first cell in the configured mode after receiving the second signal in the second time interval, the UE can directly adjust the communication mode after sending feedback information or after receiving the second signal. For example, it can use the configured mode to communicate with the first cell; or, after the second time interval, the UE can adjust the communication mode to the configured mode and then communicate with the first cell in the configured mode.

[0117] Figure 7 One embodiment provides a signal indication method, which can be applied to a first cell, such as... Figure 7 As shown, the method includes:

[0118] S701, The first cell sends a second signal to the UE.

[0119] Optionally, the first cell in step S701 above can be the UE's source cell. The second signal can be used to instruct the UE to communicate using the configured mode.

[0120] For example, the second signal mentioned above can be PDCCH, MAC CE, RRC signaling, or CSI-RS.

[0121] Furthermore, the parameters of the second signal can be configured by the first cell. For example, the time-domain resource location, time-domain resource size, time-domain resource period, frequency-domain resource location, frequency-domain resource size, sequence, CDM index, cyclic shift, etc., can be configured. The resources of the second signal can be periodic resources. Additionally, the first cell can configure a communication mode for the UE. For example, the first cell can configure a TDM pattern for the UE. Optionally, the first cell can configure a HARQ offset for the UE and use the TDM pattern for communication.

[0122] S702. The first cell communicates with the UE through the configured mode based on the second signal.

[0123] After configuring the relevant resources, parameter information, and communication mode of the second signal for the UE, the first cell sends the second signal to the UE and communicates with the UE through the configured mode according to the specific instructions of the second signal.

[0124] For example, assuming communication is performed according to the configured TDM pattern, after the UE receives the second signal sent by the first cell, it can communicate with the first cell according to the indication of the second signal. Specifically, the UE can send an uplink signal according to the scheduling timing relationship of the TDM pattern. Similarly, the first cell can also perform resource scheduling according to the indication of the second signal and the scheduling timing relationship of the TDM pattern to realize communication with the UE.

[0125] In one example, step S702 can be that after the first cell receives the feedback information sent by the UE for the second signal, it communicates with the UE through a configured mode, that is, after the first cell sends the second signal to the UE and receives the feedback information sent by the UE for the second signal, it communicates with the UE through a configured mode.

[0126] In one example, step S702 can be: after the first cell receives the feedback information sent by the UE for the second signal, after a second time interval, it communicates with the UE through a configured mode. That is, after the first cell sends the second signal to the UE and receives the feedback information from the UE for the second signal, after a second time interval, it communicates with the UE through a configured mode.

[0127] In one example, step S702 can be that after the first cell sends the second signal, it communicates with the UE through the configured mode. That is, after the first cell sends the second signal to the UE, the first cell can communicate directly with the UE through the configured mode without the UE needing to send feedback information.

[0128] In one example, step S702 can be that after the first cell sends the second signal, after a second time interval, it communicates with the UE through a configured mode. That is, after the first cell sends the second signal to the UE, after a second time interval, the first cell communicates with the UE through a configured mode. During this period, the UE does not need to send feedback information about the second signal to the first cell.

[0129] The specific length of the second time interval can be predetermined by the protocol or configured by the first cell. The length of the second time interval can be any one of the following time lengths, for example, N time slots, or N subframes, or N radio frames, or N milliseconds, where N is an integer greater than 0.

[0130] It should be noted that when the first cell receives the feedback information sent by the UE in response to the second signal after a second time interval, or after the first cell sends the second signal after a second time interval, and then communicates with the UE through the configured mode, the first cell can directly adjust the communication mode after receiving the feedback information sent by the UE, or after sending the second information to the UE. For example, it can adjust to the configured mode to communicate with the UE; or, after the second time interval, the first cell can adjust the communication mode to the configured mode and then communicate with the UE through the configured mode.

[0131] For example, such as Figure 8 As shown, the first cell transmits a PDCCH on subframe #1. This PDCCH instructs the UE to use the TDM pattern for communication, or it schedules a PDSCH. This PDSCH carries MAC CE or RRC signaling instructing the UE to use the TDM pattern for communication. After receiving the PDCCH and / or PDSCH on subframe #1, the UE can send corresponding feedback information on subframe #5 to indicate that the PDSCH has been correctly received. Simultaneously, the UE communicates with the first cell using the TDM pattern, i.e., after subframe #1 (…). Figure 8 After subframe t1, the TDM pattern is used to communicate with the first cell. Correspondingly, the first cell communicates with the first cell after subframe 1 ( Figure 8 After t1, the TDM pattern is used to communicate with the UE.

[0132] Furthermore, assuming the second time interval specified in the protocol is 3 subframes, then after the UE receives the second signal and during the second time interval, when communicating with the first cell using the TDM pattern, since the 3 subframes after subframe #1 is subframe #4, that is, after subframe #4 (… Figure 8 After subframe t2, the TDM pattern is used to communicate with the first cell. Correspondingly, the first cell communicates with the first cell after subframe 4 ( Figure 8 After t2, TDM pattern is used to communicate with UE.

[0133] Alternatively, after the UE sends the feedback information corresponding to the second signal, it uses the TDM pattern to communicate with the first cell, that is, after subframe #5 ( Figure 8 After subframe #3, the TDM pattern is used to communicate with the first cell. Correspondingly, the first cell communicates with the first cell after subframe #5. Figure 8 After t3, TDM pattern is used to communicate with UE.

[0134] Alternatively, assuming the second time interval is 3 subframes, then after the UE sends the feedback information corresponding to the second signal, when communicating with the first cell using the TDM pattern after the second time interval, since the 3 subframes after subframe #5 is subframe #8, that is, after subframe #8 ( Figure 8 After subframe #4, the TDM pattern is used to communicate with the first cell. Correspondingly, the first cell communicates with the first cell after subframe #8. Figure 8 After t4, TDM pattern is used to communicate with UE.

[0135] Figure 9 One embodiment provides a signal indication method, which can be applied to a UE, such as... Figure 9 As shown, the method includes:

[0136] S901, the UE communicates with the first cell in the configured mode at the third time.

[0137] Step S901 can be understood as the UE communicating with the first cell through the configured mode after the third time point. The first cell can be the UE's source cell, and the configured mode can be the TDM pattern.

[0138] For example, the aforementioned third time can be one of the following situations:

[0139] In the first scenario, the third time can be the time after the UE sends the third information to the second cell when it accesses the second cell in a contention-based manner.

[0140] In the second scenario, the third time can be the time after the UE receives the fourth information sent by the second cell when it accesses the second cell in a contention-based manner.

[0141] In the third scenario, the third time can be the time after the UE sends the first information to the second cell;

[0142] In the fourth scenario, the third time can be the time after the UE receives the second information sent by the second cell.

[0143] It should be noted that the aforementioned third time can be understood as a certain point in time. In the third and fourth cases mentioned above, the third time can be the time after the UE sends the first information to the second cell when the UE accesses the second cell in a contention-based manner or in a non-contention-based manner, or the time after the UE receives the second information sent by the second cell.

[0144] The second cell mentioned above can be the target cell of the UE.

[0145] In the above-mentioned scenarios of determining the third time, the UE can communicate with the first cell in the configured mode during the third time as follows:

[0146] The UE communicates directly with the first cell in the third time using the configured mode;

[0147] Alternatively, the UE may communicate with the first cell via a configured mode after a third time interval following the third time interval.

[0148] The length of the third time interval can be predefined by the protocol or configured by the first cell. The length of the third time interval can be any one of the following time lengths: N time slots, or N subframes, or N radio frames, or N milliseconds, where N is an integer greater than 0.

[0149] It should be noted that when the UE communicates with the first cell through the configured mode after the third time interval following the third time period, the UE can adjust the communication mode to the configured mode during the third time period, for example, by using the TDM pattern to communicate with the first cell; or, the UE can adjust the communication mode to the configured mode and communicate with the first cell after the third time period, after the third time interval length.

[0150] For example, such as Figure 10As shown, the UE accesses the second cell and sends the first information to the second cell on subframe #1 of radio frame #0. The second cell sends the second information to the UE on subframe #5 of radio frame #1. Then, the UE sends the third information to the second cell on subframe #9 of radio frame #0, and then the second cell sends the fourth information to the UE on subframe #3 of radio frame #1. Assume the protocol-defined time interval is 3 subframes. In some cases, after sending the first information to the second cell, the UE uses the TDM pattern to communicate with the first cell, that is, after subframe #1 of radio frame #0 (… Figure 10 After t1, the UE uses the TDM pattern to communicate with the first cell; in other cases, after the UE sends the first information to the second cell, it uses the TDM pattern to communicate with the first cell after a time interval. Since the three subframes following subframe #1 of radio frame #0 are subframe #4, the UE communicates with the first cell using the TDM pattern after subframe #4 of radio frame #0. Figure 10 After t5, TDM pattern is used to communicate with the first cell.

[0151] In some cases, after receiving the second information sent by the second area, the UE uses the TDM pattern to communicate with the first cell, that is, after subframe #5 of radio frame #0 ( Figure 10 After t2, the UE uses the TDM pattern to communicate with the first cell. In other cases, the UE uses the TDM pattern to communicate with the first cell one time interval after receiving the second information from the second cell. Since the three subframes following subframe #5 of radio frame #0 are subframe #8, the UE communicates with the first cell using the TDM pattern after subframe #8 of radio frame #0. Figure 10 After t6, the TDM pattern is used to communicate with the first cell.

[0152] In some cases, after the UE sends the third information to the second cell, it uses the TDM pattern to communicate with the first cell, that is, after subframe #9 of radio frame #0 ( Figure 10 After t3, the UE uses the TDM pattern to communicate with the first cell; in other cases, after the UE sends the third information to the second cell, it uses the TDM pattern to communicate with the first cell after a time interval. Since the three subframes following subframe #9 of radio frame #0 are subframe #2 of radio frame #1, the UE communicates with the first cell using the TDM pattern after subframe #2 of radio frame #1. Figure 10 After t7, the TDM pattern is used to communicate with the first cell.

[0153] In some cases, the UE communicates with the first cell using the TDM pattern after receiving the fourth information from the second cell, i.e., after subframe #3 of radio frame #1. Figure 10 After t4, the UE uses the TDM pattern to communicate with the first cell. In other cases, the UE uses the TDM pattern to communicate with the first cell one time interval after receiving the fourth message from the second cell. Since the three subframes following subframe #3 of radio frame #1 are subframe #7, the UE communicates with the first cell using the TDM pattern after subframe #7 of radio frame #1. Figure 10 After t8, the TDM pattern is used to communicate with the first cell.

[0154] Figure 11 One embodiment provides a signal indication method, which can be applied to a first cell, such as... Figure 11 As shown, the method includes:

[0155] S1101, The first cell receives the instruction information sent by the second cell.

[0156] For example, the first cell can be the UE's source cell, and the second cell can be the UE's target cell. The indication information can be that the second cell notifies the first cell that the UE accesses the target cell.

[0157] S1102. After receiving the indication information, the first cell communicates with the UE through the configured mode.

[0158] After receiving the instruction information from the second cell, the first cell learns that the UE has accessed the target cell. At this time, the first cell does not need to send any downlink signals to the UE, but communicates with the UE through the configured mode.

[0159] Alternatively, the above configuration can be configured to use the TDM pattern for communication.

[0160] Without any interaction between the first cell and the UE, the first cell can communicate with the UE through the configured mode after receiving the indication information from the second cell, using the above method. For example, the first cell and the UE communicate using the TDM pattern. The first cell performs resource scheduling according to the scheduling timing relationship of the TDM pattern. Similarly, the UE sends uplink signals according to the scheduling timing relationship of the TDM pattern.

[0161] Figure 12 One embodiment provides a signal indication method that can be applied to a second cell, such as... Figure 12 As shown, the method includes:

[0162] S1201, The second cell sends an instruction message to the first cell.

[0163] For example, the second cell can be the target cell of the UE, and the first cell can be the source cell of the UE. The indication information can be used to instruct the first cell to access the second cell.

[0164] Alternatively, step S1201 can be implemented in the following ways:

[0165] Method 1: After receiving the first information sent by the UE, the second cell sends an indication message to the first cell;

[0166] Method 2: After the second cell sends the second information to the UE, it sends an indication message to the first cell;

[0167] Method 3: After receiving the third information sent by the UE, the second cell sends an indication message to the first cell;

[0168] Method 4: After the second cell sends the fourth information to the UE, it sends an indication information to the first cell.

[0169] It should be noted that in Method 1 and Method 2 above, the timing for the second cell to send the indication information to the first cell can be either when the UE accesses the second cell in a contention-based mode or in a non-contention-based mode, after the second cell receives the first information sent by the UE, or after the second cell sends the second information to the UE. That is, Method 1 and Method 2 can be applied to both scenarios where the UE accesses the second cell in a contention-based mode and scenarios where the UE accesses the second cell in a non-contention-based mode.
