Description

Signal indication method, device, base station and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a signal indication method, device, base station, and storage medium.

Background

In a wireless communication system, the coverage of each cell is fixed, and cell handover needs to occur when a User Equipment (UE) moves from the coverage of one cell to the coverage of another cell. In order to achieve a handover interruption time of 0ms, the UE remains connected to the source cell during the handover, and the UE communicates with the source cell and the target cell simultaneously for a period of time after the UE accesses the target cell. However, in some cases, the UE cannot simultaneously transmit the uplink signal to the source cell and the target cell, and at this Time, the UE needs to transmit the uplink signal in a Time Division Multiplexing (TDM) manner, that is, the UE transmits the uplink signal to the source cell for a period of Time, and transmits the uplink signal to the target cell for another period of Time. However, if the uplink signal is sent too early in the TDM manner, the resource efficiency of the source cell is reduced, thereby affecting the rate experience of the UE. If the uplink signal is sent too late by using the TDM, a large amount of collision may occur to uplink resources of two cells, and also the resource efficiency may be reduced, thereby affecting the rate experience of the UE.

Detailed Description

To make the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments in the present application may be arbitrarily combined with each other without conflict, and the terms "first", "second", "third", and "fourth" in the embodiments in the present application are only used to distinguish different times, signals, information, cells, and the like, and do not indicate a limitation on the order.

In addition, in the embodiments of the present application, the words "optionally" or "exemplarily" are used for indicating as examples, illustrations or explanations. Any embodiment or design described herein as "optionally" or "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the words "optionally" or "exemplarily" etc. is intended to present the relevant concepts in a concrete fashion.

For a clearer understanding of the solutions provided by the embodiments of the present application, further explanations and illustrations of related concepts that may be involved in the embodiments of the present application are provided herein, such as:

in a wireless communication system, there are two ways for the UE to initially access, one is a contention-based random access way, and the other is a non-contention-based random access way. As shown in fig. 1, fig. 1(a) is a contention-based Random Access procedure, specifically, a UE sends first information (e.g., a Physical Random Access Channel (PRACH), or msg1) to a network side, the network side feeds back second information (e.g., a Random Access Response (RAR), or msg2) to the UE, and the UE sends third information (e.g., msg3) to the network side, and the network side sends back fourth information (e.g., msg4) to the UE, when the UE receives the fourth information and confirms the information content of the fourth information, it indicates that the UE has successful Random Access. Fig. 1(b) is a non-contention based random access procedure, specifically, a UE sends a first message (e.g., PRACH or msg1) to a network side, the network side can identify the UE after receiving the first message, and sends a second message (e.g., RAR) to the UE, and after receiving the second message, the UE indicates that the UE has successful random access.

Time division multiplexing mode (TDM pattern): in a wireless communication system, a network side configures a TDM pattern for a UE, and the TDM pattern divides a wireless resource into three parts in a time domain, namely an uplink part, a downlink part, and a special region. When the UE communicates by using the TDM pattern, the UE only transmits or receives signals in one or more partial areas in the TDM pattern, and simultaneously receives or transmits signals according to a scheduling timing relationship corresponding to the TDM pattern. Table 1 shows a configuration of a TDM pattern, specifically, the TDM pattern configures a configuration within each radio frame (with a time length of 10ms), where the unit indicated by the configuration is a radio subframe, where D denotes that the subframe is a downlink portion in the TDM pattern, U denotes that the subframe is an uplink portion in the TDM pattern, and S denotes that the subframe is a special region in the TDM pattern. The UE communicates according to the configuration of the TDM pattern, that is, the UE only transmits on the uplink subframe configured in the TDM pattern, and simultaneously receives or transmits according to the scheduling timing relationship corresponding to the TDM pattern.

TABLE 1

On the basis of the above concept, fig. 2 is a signaling method provided in an embodiment, which may be applied to a UE, and as shown in fig. 2, the method includes:

s201, the UE sends a first signal to a first cell.

Optionally, in this embodiment, the first cell may be a source cell of the UE. The first signal may be used to instruct the first cell to communicate using the configured mode.

For example, the first Signal may be a Physical Uplink Control Channel (PUCCH), a PRACH, a Sounding Reference Signal (SRS), a medium Access Control Element (MAC CE), or Radio Resource Control protocol signaling (RRC) signaling.

Further, parameters of the first signal may be configured by the first cell, for example, a time domain resource position, a time domain resource size, a time domain resource period, a frequency domain resource position, a frequency domain resource size, a sequence, a code division Multiplexing Index (CDM Index), a cyclic shift, a frequency hopping bandwidth, an SRS Index, a pracindex, a transmission comb value, and the like are configured, where the resource of the first signal may be a periodic resource. Moreover, the first cell may configure a communication mode for the UE, for example, the first cell configures a TDM pattern for the UE, and optionally, the first cell may also configure a Hybrid Automatic Repeat reQuest offset (HARQ offset) for the UE and perform communication in the TDM pattern manner.

S202, the UE communicates with the first cell through the configured mode according to the first signal.

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

The embodiment of the application provides a signal indication method, wherein a UE sends a first signal to a first cell, the first signal is used for indicating to use a configured mode for communication, and further, the UE communicates with the first cell through the configured mode according to the first signal. By the method, the UE and the first cell can communicate by adopting the configured mode and the corresponding resource time sequence scheduling through the indication of the first signal, so that the resource use efficiency and the rate experience of the UE are improved.

In an example, in step S201, the UE transmits the first signal to the first cell, which may be implemented in several optional manners as follows:

in a first mode, before sending first information to a second cell accessed by UE, the UE sends a first signal to a first cell;

in the second mode, after the UE sends the first information to the second cell accessed by the UE, the UE sends a first signal to the first cell;

it should be noted that, the two manners may be to transmit the first signal to the first cell when the UE accesses the second cell in a contention-based random access manner or a non-contention-based random access manner.

When the UE accesses the second cell in a non-competitive mode, the UE sends a first signal to the first cell after receiving second information sent by the second cell;

and fourthly, when the UE accesses the second cell in a competition mode, the UE sends the first signal to the first cell after receiving the fourth information sent by the second cell.

The second cell may be a target cell of the UE.

In addition, when the first signal sent by the UE is the PUCCH, the first signal resource configured by the first cell for the UE may be at least a specially configured PUCCH resource, that is, the 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 may simultaneously indicate the PUCCH resource for indicating to use the configured mode for communication. Alternatively, the PUCCH may be a Short PUCCH (SPUCCH).

When the first signal sent by the UE is a PRACH, the first signal resource configured by the first cell for the UE may be at least a specifically configured PRACH resource, such as a preamble index (preamble index), that is, the resource is different from other PRACH resources used for initial access, for example, at least one of configuration parameters of two PRACH resources is different. Optionally, when configuring the PRACH resource, the first cell may indicate the PRACH resource to indicate to use the configured mode for communication at the same time.

When the first signal sent by the UE is an SRS, the first signal resource configured by the first cell for the UE may be at least a specifically configured SRS resource, that is, the SRS resource is different from other SRS resources used for channel measurement, for example, at least one of configuration parameters of two SRSs is different. Optionally, when the SRS resource is configured, the first cell may simultaneously indicate the SRS resource to indicate to use the configured mode for communication.

Further, the UE communicates with the first cell through the configured mode according to the first signal, so that the UE can directly communicate with the first cell through the configured mode after sending the first signal;

or after a first time interval after the UE sends the first signal, the UE communicates with the first cell through the configured mode;

or, the UE receives feedback information sent by the first cell for the first signal, and communicates with the first cell through the configured mode, that is, after the UE sends the first signal, the UE receives the feedback information sent by the first cell, and when the UE receives the feedback information sent by the first cell for the first signal, the UE communicates with the first cell through the configured mode;

or after receiving a first time interval after the first cell transmits the feedback information for the first signal, the UE communicates with the first cell through the configured mode, that is, after the UE has transmitted the first signal, the UE receives the feedback information transmitted by the first cell, and after receiving the first time interval after the first cell receives the feedback information for the first signal, the UE communicates with the first cell through the configured mode.

The specific time length of the first time interval may be predefined by a protocol, or configured by the first cell, where the length of the first time interval may be any one of the following time lengths, for example, N slots, or N subframes, or N radio frames, or N milliseconds, where N is an integer greater than 0.

It should be noted that, when the UE communicates with the first cell in the configured mode after the first time interval after sending the first signal or after receiving the first time interval after receiving the feedback information sent by the first cell for the first signal, the UE may directly adjust the communication mode after sending the first signal or after receiving the feedback information sent by the first cell, for example, adopt the configured mode, and further communicate with the first cell after the first time interval; or, the UE adjusts the communication mode to the configured mode after the first time interval and then communicates with the first cell through the configured mode.

After the UE communicates with the first cell in several optional manners, the UE and the first cell may communicate according to the configured communication mode according to the indication of the first signal. For example, the UE sends an uplink signal according to the scheduling timing relationship of the TDM pattern, and similarly, the first cell performs resource scheduling according to the indication of the first signal by using the scheduling timing relationship of the TDM pattern.

Fig. 3 is a signal indication method according to an embodiment, which may be applied to a first cell, and as shown in fig. 3, the method includes:

s301, the first cell receives a first signal sent by the UE.

The first cell may be a source cell of the UE, and the first signal may be used to instruct the first cell to communicate using the configured mode.

Illustratively, the first signal received by the first cell may be PUCCH, PRACH, SRS, MAC CE, RRC signaling.

Further, the first cell may configure parameters of the first signal for the UE, for example, configure a time domain resource location, a time domain resource size, a time domain resource period, a frequency domain resource location, a frequency domain resource size, a sequence, a CDM index, a cyclic shift, a frequency hopping bandwidth, an SRS index, a PRACH index, a transmission comb value, and the like, where the resource of the first signal may be a periodic resource. Moreover, the first cell may configure a communication mode for the UE, for example, the first cell configures a TDM pattern for the UE, and optionally, the first cell may configure HARQ offset for the UE and may perform communication in the TDM pattern manner.

S302, the first cell communicates with the UE through the configured mode according to the first signal.

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

The embodiment of the application provides a signal indication method, wherein a first cell receives a first signal sent by a UE, the first signal is used for indicating to use a configured mode for communication, and the first cell communicates with the UE through the configured mode according to the first signal. Through the method, the first cell and the UE communicate by adopting the configured mode and the corresponding resource time sequence scheduling through the indication of the first signal, so that the resource use efficiency and the rate experience of the UE are improved.

In an example, after receiving the first signal sent by the UE, the first cell may communicate with the UE through the configured mode, that is, after receiving the first signal, the first cell directly communicates with the UE through the configured mode.

In one example, after a first time interval after the first cell receives the first signal sent by the UE, the first cell communicates with the UE through the configured mode, that is, after the first cell receives the first signal, the first cell communicates with the UE through the configured mode after the first time interval is a length of the first time interval;

in one example, after sending the feedback information for the received first signal, the first cell communicates with the UE in the configured mode, that is, after receiving the first signal sent by the UE and sending the feedback information to the UE, the first cell communicates with the UE in the configured mode;

in one example, the first cell communicates with the UE in the configured mode after a first time interval after sending the feedback information for the received first signal, that is, the first cell receives the first signal sent by the UE and communicates with the UE in the configured mode after a first time interval after sending the feedback information to the UE.

It should be noted that, when the first cell communicates with the UE in the configured mode after a first time interval after receiving the first signal sent by the UE, or after a first time interval after the first cell sends the feedback information for the received first signal, the first cell may directly adjust the communication mode, for example, to the configured mode TDM pattern, after receiving the first signal, or after sending the feedback information for the first signal, and further communicate with the UE after the first time interval; or, the first cell adjusts the communication mode to the configured mode after the first time interval and then communicates with the UE through the configured mode.

Exemplarily, as shown in fig. 4, a PUCCH configured for the UE by the first cell may be transmitted on subframes #1, #7, where the PUCCH is used for the UE to notify the first cell to use TDM pattern for communication. If the UE uses the TDM pattern to perform communication after sending the first signal, that is, if the UE sends the PUCCH in subframe #1, the UE uses the TDM pattern to perform communication with the first cell after subframe #1 (after t1 in fig. 4). Accordingly, after receiving the PUCCH transmitted by the UE in subframe #1, the first cell communicates with the UE using TDM pattern in subframe #1 (after t1 in fig. 4). If the UE uses the TDM pattern to perform communication after a time interval after sending the uplink signal is completed, for example, if the UE sends the PUCCH in subframe #1 and the time interval is 3 subframes, the UE uses the TDM pattern to perform communication with the first cell in subframe #4 (after t2 in fig. 4). Accordingly, after receiving the PUCCH transmitted by the UE in subframe #1, the first cell performs communication with the UE using TDM pattern in subframe #4 (after t2 in fig. 4) after 3 subframes.

Similarly, if the first signal is the PRACH or SRS, the indicating manner of the PRACH or SRS is the same as that of the PUCCH, and details of the embodiment of the present application are not repeated herein.

As shown in fig. 5, if the first signal is MAC CE or RRC signaling, it indicates that TDM pattern is used for communication. The UE sends a PUSCH on subframe #1, where the PUSCH carries a MAC CE or RRC signaling indicating that the TDM pattern is used for communication, and after receiving the PUSCH, the first cell sends corresponding feedback information on subframe #5 to confirm to the UE that the PUSCH has been correctly received by the first cell. The UE communicates using TDM pattern after receiving the feedback information, that is, the UE communicates with the first cell using TDM pattern in subframe #5 (after t3 in fig. 5). Accordingly, after the first cell transmits the feedback information of PUSCH correct reception on subframe #5, the first cell communicates with the UE using TDM pattern after subframe #5 (after t3 in fig. 5). If the UE communicates using the TDM pattern after the first time interval after receiving the feedback information, if the time interval is 3 subframes, the UE communicates with the first cell using the TDM pattern after subframe #8 (3 subframes after subframe # 5). Accordingly, the first cell communicates with the UE using TDM pattern after subframe #8 after 3 subframes after transmitting feedback information for PUSCH correct reception on subframe # 5.

Fig. 6 is a signaling method according to an embodiment, which may be applied to a UE, and as shown in fig. 6, the method includes:

s601, the UE receives a second signal sent by the first cell.

Optionally, in this embodiment, the first cell may be a source cell of the UE. The second signal may be used to instruct the UE to communicate using the configured mode.

For example, the second Signal may be a Physical Downlink Control Channel (PDCCH), a MAC CE, an RRC signaling, and a Channel State information reference Signal (CSI-RS).

Further, parameters of the second signal may be configured by the first cell, for example, a time domain resource position, a time domain resource size, a time domain resource period, a frequency domain resource position, a frequency domain resource size, a sequence, a CDM index, a cyclic shift, and the like are configured, where the resources of the second signal may be periodic resources. And the first cell may configure a communication mode for the UE, for example, the first cell configures TDM pattern for the UE, and optionally, the first cell may configure HARQ offset for the UE and perform communication in a tdmp pattern manner.

In addition, when the second signal received by the UE is a PDCCH, the second signal resource configured by the first cell for the UE may be at least a specially configured PDCCH resource, that is, the PDCCH resource is different from other resources used for a PDCCH transmitted by Downlink Control Information (DCI), for example, at least one of configuration parameters of the two PDCCHs is different. Optionally, when the first cell configures the PDCCH resource, the first cell may simultaneously indicate the PDCCH resource to instruct the UE to use the configured mode for communication. The PDCCH may be a Short PDCCH (SPDCCH) or an Enhanced Physical Downlink Control Channel (EPDCCH).

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

And S602, the UE communicates with the first cell through the configured mode according to the second signal.

After receiving the second signal sent by the first cell, the UE may communicate with the first cell in the configured mode according to the indication of the second signal, for example, the UE communicates according to the TDM pattern configured by the first cell according to the indication of the second signal, and sends the uplink signal according to the scheduling timing relationship of the TDM pattern.

In one example, after sending the feedback information to the first cell according to 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 sends the feedback information to the first cell, and then communicates with the first cell through the configured mode;

in an example, after a second time interval after the UE sends the feedback information to the first cell according to 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 sends the feedback information to the first cell after the second time interval, and communicates with the first cell through the configured mode;

in an 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 can directly communicate with the first cell through the configured mode without sending feedback information to the second cell;

in an example, after a second time interval after the UE receives 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 after the second time interval, the UE communicates with the first cell through the configured mode.

The specific time length of the second time interval may be predefined by a protocol, or the length of the second time interval configured by the first cell may 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.

It should be noted that, when the UE communicates with the first cell through the configured mode after the second time interval after sending the feedback information to the first cell according to the second signal, or communicates with the first cell through the configured mode after the second time interval after receiving the second signal, the UE may directly adjust the communication mode after sending the feedback information or after receiving the second signal, for example, communicate with the first cell in the configured mode; or, after the second time interval, the UE adjusts the communication mode to the configured mode, and then communicates with the first cell through the configured mode.

Fig. 7 is a signaling method according to an embodiment, which may be applied to a first cell, and as shown in fig. 7, the method includes:

s701, the first cell sends a second signal to the UE.

Optionally, the first cell in step S701 may be a source cell of the UE. The second signal may be used to instruct the UE to communicate using the configured mode.

Illustratively, the second signal may be PDCCH, MAC CE, RRC signaling, CSI-RS.

Further, parameters of the second signal may be configured by the first cell, for example, a time domain resource position, a time domain resource size, a time domain resource period, a frequency domain resource position, a frequency domain resource size, a sequence, a CDM index, a cyclic shift, and the like are configured, where the resources of the second signal may be periodic resources. Moreover, the first cell may configure a communication mode for the UE, for example, the first cell may configure a TDM pattern for the UE, and optionally, the first cell may configure HARQ offset for the UE and perform communication in the TDM pattern manner.

S702, the first cell communicates with the UE through the configured mode according to the second signal.

And after configuring the related resources, the parameter information and the 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 indication of the second signal.

For example, assuming that communication is performed according to the configured TDM pattern, after receiving the second signal sent by the first cell, the UE may communicate with the first cell according to an indication of the second signal, specifically, may send an uplink signal to the UE according to the scheduling timing relationship of the tdmp pattern, and similarly, the first cell may also perform resource scheduling according to the indication of the second signal by using the scheduling timing relationship of the TDM pattern, so as to implement communication with the UE.

In an example, step S702 may be that the first cell communicates with the UE through the configured mode after receiving the feedback information sent by the UE for the second signal, that is, the first cell sends the second signal to the UE and communicates with the UE through the configured mode after receiving the feedback information sent by the UE for the second signal;

in an example, step S702 may be that the first cell communicates with the UE in a configured mode after receiving a second time interval after the UE receives the feedback information for the second signal, that is, the first cell transmits the second signal to the UE, and communicates with the UE in the configured mode after receiving the feedback information for the second signal and after a second time interval length;

in an example, step S702 may be that, after the first cell issues the second signal, the first cell communicates with the UE through the configured mode, that is, after the first cell sends the second signal to the UE, the first cell may directly communicate with the UE through the configured mode without sending feedback information by the UE;

in an example, step S702 may be that after a second time interval after the first cell issues the second signal, the first cell communicates with the UE through the configured mode, that is, after the first cell sends the second signal to the UE and after the second time interval is a length of the second time interval, the first cell communicates with the UE through the configured mode, during which the UE does not need to send feedback information for the second signal to the first cell.

It should be noted that, when the first cell communicates with the UE through the configured mode after receiving the second time interval after the first cell receives the feedback information sent by the UE for the second signal, or after the first cell issues the second signal, the first cell may directly adjust the communication mode after receiving the feedback information sent by the UE, or after issuing the second information to the UE, for example, adjust the communication mode to the configured mode to communicate with the UE; or, the first cell adjusts the communication mode to the configured mode after the second time interval, and then communicates with the UE through the configured mode.

Exemplarily, as shown in fig. 8, the first cell transmits a PDCCH on subframe #1, where the PDCCH instructs the UE to use a tdmp pattern for communication, or the PDCCH schedules a PDSCH carrying MAC CE or RRC signaling that instructs the UE to use a TDM pattern for communication, and after receiving the PDCCH and/or PDSCH on subframe #1, the UE may transmit corresponding feedback information on subframe #5 to indicate that the PDSCH has been correctly received. Meanwhile, the UE communicates with the first cell using TDM pattern, i.e., the UE communicates with the first cell using TDM pattern after subframe #1 (after t1 in fig. 8). Accordingly, the first cell communicates with the UE using TDM patterns after subframe 1 (after t1 in fig. 8).

Further, assuming that the second time interval specified by the protocol is 3 subframes, when the UE communicates with the first cell using the TDM pattern after receiving the second signal in the second time interval, since 3 subframes after subframe #1 are subframe #4, the UE communicates with the first cell using the TDM pattern after subframe #4 (after t2 in fig. 8). Accordingly, the first cell communicates with the UE using TDM patterns after subframe 4 (after t2 in fig. 8).

Or, after sending the feedback information corresponding to the second signal, the UE uses the TDM pattern to communicate with the first cell, that is, after subframe #5 (after t3 in fig. 8), the UE uses the TDM pattern to communicate with the first cell. Accordingly, the first cell communicates with the UE using TDM patterns after subframe #5 (after t3 in fig. 8).

Or, assuming that the second time interval is 3 subframes, when the UE communicates with the first cell using the TDM pattern after the UE has sent the feedback information corresponding to the second signal in the second time interval, since 3 subframes after the subframe #5 are the subframe #8, that is, the UE communicates with the first cell using the TDM pattern after the subframe #8 (after t4 in fig. 8). Accordingly, the first cell communicates with the UE using TDM patterns after subframe #8 (after t4 in fig. 8).

Fig. 9 is a signaling method according to an embodiment, which may be applied to a UE, and as shown in fig. 9, the method includes:

and S901, the UE communicates with the first cell through the configured mode at the third time.

Step S901 may be understood as that the UE communicates with the first cell through the configured mode after the time point of the third time, where the first cell may be a source cell of the UE, and the configured mode may adopt a TDM pattern manner.

Illustratively, the third time may be the following cases:

in the first case, the third time may be a time after the UE sends the third information to the second cell when accessing the second cell in a contention mode;

in a second case, the third time may be a time after receiving fourth information sent by the second cell when the UE accesses the second cell in a contention mode;

in a third case, the third time may be a time after the UE sends the first information to the second cell;

in a fourth case, the third time may be a time after the UE receives the second information sent by the second cell.

It should be noted that the third time may be understood as a certain time point, and for the third case and the fourth case, the third time may be a time after the UE sends the first information to the second cell when the UE accesses the second cell in a contention manner, or when the UE accesses the second cell in a non-contention manner, or a time after the UE receives the second information sent by the second cell.

The second cell may be a target cell of the UE.

In the above several cases of determining the third time, the communicating, by the UE, with the first cell through the configured mode at the third time may be:

the UE directly communicates with the first cell through the configured mode at the third time;

or after a third time interval after the third time, the UE communicates with the first cell through the configured mode.

The third time interval length may be predefined by a protocol, or configured by the first cell, and may be any one of the following time intervals: n slots, or N subframes, or N radio frames, or N milliseconds, where N is an integer greater than 0.

It should be noted that, when the UE communicates with the first cell through the configured mode after the third time interval after the third time, the UE may adjust the communication mode to the configured mode at the third time, for example, communicate with the first cell in a tdmp pattern manner; or, the UE may adjust the communication mode to the configured mode after the third time and after the third time interval length, and communicate with the first cell.

Illustratively, as shown in fig. 10, the UE accesses the second cell, transmits the first information to the second cell on subframe #1 of radio frame #0, the second cell transmits the second information to the UE on subframe #5 of radio frame #1, then the UE transmits the third information to the second cell on subframe #9 of radio frame #0, and then the second cell transmits the fourth information to the UE on subframe #3 of radio frame # 1. Assume that the protocol specifies a time interval of 3 subframes. In some cases, the UE communicates with the first cell using TDM pattern after sending the first information to the second cell, that is, the UE communicates with the first cell using TDM pattern after subframe #1 of radio frame #0 (after t1 in fig. 10); in other cases, the UE communicates with the first cell using TDM pattern after a time interval after sending the first information to the second cell, and since the next 3 subframes of subframe #1 of radio frame #0 are subframe #4, the UE communicates with the first cell using tdmp pattern after subframe #4 of radio frame #0 (after t5 in fig. 10).

In some cases, the UE communicates with the first cell using TDM pattern after receiving the second information sent by the second region, i.e., the UE communicates with the first cell using TDM pattern after subframe #5 of radio frame #0 (after t2 in fig. 10). In other cases, the UE communicates with the first cell using TDM pattern after a time interval after receiving the second information sent by the second cell, and since the next 3 subframes of subframe #5 of radio frame #0 are subframe #8, the UE communicates with the first cell using TDM pattern after subframe #8 of radio frame #0 (after t6 in fig. 10).

In some cases, the UE communicates with the first cell using TDM pattern after sending the third information to the second cell, that is, the UE communicates with the first cell using TDM pattern after subframe #9 of radio frame #0 (after t3 in fig. 10); in other cases, the UE communicates with the first cell using tdmp pattern after a time interval after sending the third information to the second cell, and since subframe #9 of radio frame #0 is followed by 3 subframes of subframe #2 of radio frame #1, the UE communicates with the first cell using TDM pattern after subframe #2 of radio frame #1 (after t7 in fig. 10).

In some cases, the UE communicates with the first cell using TDM pattern after receiving the fourth information sent by the second cell, i.e., the UE communicates with the first cell using TDM pattern after subframe #3 of radio frame #1 (after t4 in fig. 10). In other cases, the UE communicates with the first cell using TDM pattern after a time interval after receiving the fourth information sent by the second cell, and since the next 3 subframes of subframe #3 of radio frame #1 are subframe #7, the UE communicates with the first cell using TDM pattern after subframe #7 of radio frame #1 (after t8 in fig. 10).

Fig. 11 is a signaling method according to an embodiment, which may be applied to a first cell, and as shown in fig. 11, the method includes:

s1101, the first cell receives indication information sent by the second cell.

For example, the first cell may be a source cell of the UE, and the second cell may be a target cell of the UE. The indication information may inform the first cell for the second cell, and the UE accesses the target cell.

And S1102, after receiving the indication information, the first cell communicates with the UE through the configured mode.

After receiving the indication information of the second cell, the first cell learns that the UE has accessed the target cell, and at this time, the first cell communicates with the UE in the configured mode without sending any downlink signal to the UE.

Optionally, the configured mode may be a TDM pattern mode for communication.

Under the condition that the first cell and the UE do not need to interact, the first cell can communicate with the UE through the configured mode after receiving the indication information of the second cell through the mode. For example, the first cell and the UE communicate in a TDM pattern manner, the first cell performs resource scheduling according to the scheduling timing relationship of the TDM pattern, and similarly, the UE transmits an uplink signal according to the scheduling timing relationship of the tdmp pattern.

Fig. 12 is a signal indication method according to an embodiment, which may be applied to a second cell, and as shown in fig. 12, the method includes:

s1201, the second cell sends indication information to the first cell.

For example, the second cell may be a target cell of the UE, and the first cell may be a source cell of the UE. The indication information may be used to indicate to the first cell that the UE accesses the second cell.

Alternatively, the step S1201 can be implemented by the following methods:

in the first mode, after receiving first information sent by UE, the second cell sends indication information to the first cell;

in the second mode, after the second cell issues the second information to the UE, the second cell sends the indication information to the first cell;

in the third mode, after receiving third information sent by the UE, the second cell sends indication information to the first cell;

and in the fourth mode, after the second cell issues the fourth information to the UE, the second cell sends the indication information to the first cell.

It should be noted that, in the first and second manners, the timing when the second cell sends the indication information to the first cell may be that, when the UE accesses the second cell in a contention manner, or accesses the second cell in a non-contention manner, the second cell receives the first information sent by the UE, or the second cell issues the second information to the UE. That is, the first and second manners may be applied to a scenario in which the UE accesses the second cell in a contention manner, or may be applied to a scenario in which the UE accesses the second cell in a non-contention manner.
