Technical Field

Background

A Physical Downlink Control Channel (PDCCH) is a Channel for carrying Downlink Control Information (DCI). In practical applications, a base station may send DCI to a User Equipment (UE) through a PDCCH, and the UE may monitor the PDCCH to receive the DCI sent by the base station on the PDCCH in time. In order to reduce power consumption, the UE in the connected state usually does not monitor the PDCCH uninterruptedly, but periodically switches from the dormant state to the awake state, and monitors the PDCCH in the awake state, and this mechanism for monitoring the PDCCH is usually called a Discontinuous Reception (DRX) mechanism.

In the related art, the base station may configure a DRX parameter for the UE semi-statically, where the DRX parameter is a parameter that the UE needs to use to monitor the PDCCH by using a DRX mechanism, and the UE may monitor the PDCCH according to the DRX parameter configured semi-statically by the base station.

Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In a wireless communication system, a base station may transmit Downlink Control Information (DCI) to a User Equipment (UE) through a Physical Downlink Control Channel (PDCCH) so as to schedule the UE using the transmitted DCI.

Because the UE cannot predict the DCI sending time of the base station under normal conditions, in a wireless communication system, the UE needs to monitor the PDCCH in real time according to a certain monitoring mechanism, so as to receive the DCI sent by the base station in time.

In a possible implementation manner, the UE may monitor the PDCCH uninterruptedly, that is, the UE may monitor the PDCCH in each subframe. However, since the UE needs to perform blind detection for 44 times at most when monitoring each PDCCH, and in general, most PDCCHs do not carry DCI transmitted to the UE by the base station, such a manner may cause a large waste of power consumption of the UE, thereby affecting the standby time of the UE.

In order to reduce the power consumption of the UE, the wireless communication system introduces a Discontinuous Reception (DRX) mechanism.

As shown in fig. 1, in the DRX mechanism, the UE may monitor the PDCCH according to DRX cycles (english: DRX cycles), wherein one DRX Cycle may include a monitored Duration (english: On Duration) and a non-monitored Duration (english: Opportunity for DRX). In the connected state, the UE may enter an awake state during a monitoring period of the DRX cycle, and in the awake state, the UE may monitor the PDCCH, and simultaneously, the UE may enter a sleep state during a non-monitoring period of the DRX cycle, and in the sleep state, the UE may not monitor the PDCCH. To ensure that the UE can successfully receive the DCI, the base station may determine a monitored duration of each DRX cycle and transmit the DCI to the UE within the monitored duration.

In the DRX mechanism, the UE needs to monitor the PDCCH according to DRX parameters configured by the base station, where the DRX parameters may include a monitoring Duration (english: On Duration Timer), a monitoring extension Duration (english: DRX-Inactivity Timer), a Short DRX Cycle Duration (english: Short DRX-Cycle), a Long DRX Cycle Duration (english: Long DRX-Cycle), a Short DRX Cycle Duration (english: DRX-Cycle), and the like.

In the following, the embodiments of the present disclosure will briefly explain the meaning of these DRX parameters:

1. the duration of the monitoring.

The monitoring duration refers to the duration of the monitoring period in the DRX cycle. Under the condition that the duration of the DRX period is fixed, the longer the monitoring duration is, the greater the monitoring intensity of the UE on the PDCCH is, and correspondingly, the greater the power consumption of the UE is, and conversely, the shorter the monitoring duration is, the smaller the monitoring intensity of the UE on the PDCCH is, and correspondingly, the smaller the power consumption of the UE is.

2. The extended duration is monitored.

In the latter period of the monitoring period, the base station may have just one large data to be sent to the UE, and in the remaining monitoring period, the base station cannot completely send the data to the UE.

In order to reduce the transmission delay of data, the DRX mechanism can introduce the concept of monitoring the extended duration. In the monitoring period, when the UE receives the DCI issued by the base station on the PDCCH, the UE may start timing, and when the timing duration of the UE does not reach the monitoring extension duration, even if the monitoring period is finished, the UE does not enter the non-monitoring period, that is, does not enter the sleep state, but continuously monitors the PDCCH, and when the timing duration reaches the monitoring extension duration, the UE enters the non-monitoring period.

As can be seen from the above description, the longer the monitoring extension duration is, the greater the monitoring intensity of the PDCCH by the UE is, and accordingly, the greater the power consumption of the UE is, and conversely, the shorter the monitoring extension duration is, the smaller the monitoring intensity of the PDCCH by the UE is, and accordingly, the smaller the power consumption of the UE is.

3. A short DRX cycle duration and a long DRX cycle duration.

The short DRX cycle duration and the long DRX cycle duration are both used to characterize the duration of the DRX cycle, except that the duration of the DRX cycle characterized by the short DRX cycle duration is shorter than the duration of the DRX cycle characterized by the long DRX cycle duration.

In the DRX mechanism, the base station may configure the UE with a short DRX cycle duration or a long DRX cycle duration according to a service scenario of the UE. For example, for some communication services in which data interaction between the UE and the base station is frequent, the base station may configure the UE with a short DRX cycle duration, and for some communication services in which data interaction between the UE and the base station is not frequent, the base station may configure the UE with a long DRX cycle duration.

Under the short DRX cycle duration, the UE can enter the awakening state more frequently, namely, the UE can monitor the PDCCH more frequently, so that under the short DRX cycle duration, the monitoring intensity of the PDCCH by the UE is higher, and correspondingly, the power consumption of the UE is also higher; and under the long DRX period, the frequency of the UE entering the awake state is low, that is, the frequency of the UE monitoring the PDCCH is low, so that under the long DRX cycle period, the monitoring intensity of the UE on the PDCCH is low, and accordingly, the power consumption of the UE is also low.

In some cases, the base station may configure one short DRX cycle duration and one long DRX cycle duration for the UE at the same time, and the UE may switch between the short DRX cycle duration and the long DRX cycle duration according to a monitoring condition of the UE on the PDCCH.

4. A short DRX cycle number.

If the UE does not receive the DCI sent by the base station on the PDCCH in n consecutive DRX cycles with the duration of the short DRX cycle, it indicates that the frequency of data interaction between the UE and the base station is low, and at this time, the UE may switch the duration of the short DRX cycle to the duration of the long DRX cycle, so as to save the power consumption of the UE. Wherein n is the short DRX period number which is a positive integer.

As can be seen from the above description, the smaller the number of short DRX cycles, the greater the monitoring strength of the PDCCH by the UE, and accordingly, the greater the power consumption of the UE, and conversely, the greater the number of short DRX cycles, the smaller the monitoring strength of the PDCCH by the UE, and accordingly, the smaller the power consumption of the UE.

Table 1 shows possible values of DRX parameters in a wireless communication system.

TABLE 1

In the related art, the base station may semi-statically configure the DRX parameters for the UE, for example, the base station may configure the DRX parameters for the UE through higher layer signaling. Because the base station is configured semi-statically, the DRX parameters configured for the UE by the base station need to meet the requirement of general communication services on data transmission delay, in order to meet the requirement, the monitoring extension duration is usually longer in the DRX parameters configured for the UE by the base station, and the base station tends to configure a short DRX cycle duration for the UE, so as to enhance the monitoring of the PDCCH by the UE.

However, in practical applications, the data volume of the communication service often changes dynamically, that is, the data volume of the communication service may be exploded intensively in a certain period of time, and the data volume of the communication service may be relatively small in another period of time.

When the communication service data volume of the UE is intensively burst, the base station needs to send a large amount of DCI to the UE, at this time, the DRX parameters configured by the base station for the UE in a semi-static manner may not meet the delay requirement, and when the communication service data volume of the UE is relatively small, the DCI sent by the base station to the UE is also small, at this time, the UE monitors the PDCCH according to the DRX parameters configured in the semi-static manner by the base station, which may cause a certain waste on the power consumption of the UE, thereby affecting the standby time of the UE.

Therefore, in the related art, the configuration mode of the DRX parameters is difficult to adapt to the dynamically changing communication traffic data volume, and the flexibility of the UE performing PDCCH monitoring according to the DRX parameters configured by the configuration mode is poor.

The embodiment of the disclosure provides a channel monitoring method, which can improve the flexibility of monitoring a PDCCH by UE. In the channel monitoring method provided by the embodiment of the present disclosure, the UE may receive the target DCI sent by the base station, and monitor the PDCCH according to the DRX parameter indicated by the parameter indication information carried in the target DCI, because DCI is sent more flexibly and the real-time performance is strong, the base station may dynamically configure the DRX parameter through the target DCI, and the UE may monitor the PDCCH according to the DRX parameter dynamically configured by the base station, so that compared with a manner in which the base station semi-statically configures the DRX parameter, the flexibility of monitoring the PDCCH by the UE may be improved, and it is ensured that the monitoring of the PDCCH by the UE can be adapted to the communication traffic data volume that dynamically changes.

Next, an implementation environment related to the channel monitoring method provided by the embodiment of the present disclosure will be described.

Fig. 2 is a schematic diagram of an implementation environment related to a channel monitoring method provided in an embodiment of the present disclosure. As shown in fig. 2, the implementation environment may include a base station 10 and a UE 20. The base station 10 and the UE20 may be connected through a communication network, the UE20 being any one of the cells served by the base station 10.

The Communication network may be a Fifth Generation Mobile Communication Technology (5G), a Long Term Evolution (LTE), or another Communication network similar to The LTE Communication network or The 5G Communication network.

Fig. 3 is a flowchart illustrating a channel monitoring method according to an exemplary embodiment, which may be used in the UE20 shown in fig. 2, and as shown in fig. 3, the channel monitoring method includes the following steps:

step 301, the UE receives the target DCI transmitted by the base station.

The target DCI carries parameter indication information, and the parameter indication information is used for indicating DRX parameters.

And step 302, the UE monitors the PDCCH according to the DRX parameters indicated by the parameter indication information.

To sum up, in the channel monitoring method provided in the embodiment of the present disclosure, the target DCI transmitted by the base station is received, and the PDCCH is monitored according to the DRX parameter indicated by the parameter indication information carried in the target DCI, because the DCI is transmitted flexibly and the real-time performance is high, the base station can dynamically configure the DRX parameter through the target DCI, and the UE can monitor the PDCCH according to the DRX parameter dynamically configured by the base station, so that compared with a manner in which the base station semi-statically configures the DRX parameter, the flexibility of monitoring the PDCCH by the UE can be improved, and the monitoring of the PDCCH by the UE can be adapted to the communication service data volume that dynamically changes.

Fig. 4 is a flowchart illustrating a channel monitoring method according to an exemplary embodiment, which may be used in the base station 10 shown in fig. 2, as shown in fig. 4, the channel monitoring method includes the following steps:

step 401, the base station sends the target DCI to the UE.

The target DCI carries parameter indication information, and the parameter indication information is used for indicating DRX parameters. And the UE is used for monitoring the PDCCH according to the DRX parameters indicated by the parameter indication information.

To sum up, the channel monitoring method provided in the embodiment of the present disclosure, by sending the target DCI to the UE, enables the UE to monitor the PDCCH according to the DRX parameter indicated by the parameter indication information carried in the target DCI, and since the DCI is sent more flexibly and the real-time performance is stronger, the base station can dynamically configure the DRX parameter through the target DCI, and the UE can monitor the PDCCH according to the DRX parameter dynamically configured by the base station, so that compared with a manner in which the base station semi-statically configures the DRX parameter, the flexibility of monitoring the PDCCH by the UE can be improved, and the monitoring of the PDCCH by the UE can be adapted to the communication service data volume that dynamically changes.

Fig. 5 is a flow chart illustrating a channel monitoring method according to an exemplary embodiment, which may be used in the implementation environment shown in fig. 2, as shown in fig. 5, the channel monitoring method including the steps of:

step 501, the base station sends the target DCI to the UE.

In one embodiment of the present disclosure, the base station may monitor a change of the communication traffic data amount of the UE in real time or periodically. When it is monitored that the communication service data volume of the UE changes and the amplitude of the change meets a preset condition, or when it is monitored that the communication service data volume of the UE changes and the changed communication service data volume meets another preset condition, the base station may determine the DRX parameter according to the change condition of the communication service data volume of the UE. Then, the base station may indicate the DRX parameter to the UE through the target DCI, so that the UE can monitor the PDCCH according to the DRX parameter. Because the DCI is transmitted flexibly and has strong real-time performance, and the base station can determine the DRX parameters in real time according to the change condition of the communication service data volume of the UE, in the embodiment of the disclosure, the base station can realize dynamic configuration of the DRX parameters for the UE, so that the monitoring of the PDCCH by the UE can be adapted to the change of the communication service data volume of the UE, and the monitoring flexibility of the PDCCH by the UE is improved.

For example, when it is monitored that the communication traffic data volume of the UE increases and the increased magnitude is greater than the first magnitude threshold, or when it is monitored that the communication traffic data volume of the UE increases and the increased communication traffic data volume is greater than the first data volume threshold, the base station may determine at least one of the monitoring duration, the monitoring extension duration, the short DRX cycle duration, and the short DRX cycle number according to the increased magnitude of the communication traffic data volume of the UE, or according to the increased communication traffic data volume, and indicate the at least one of the monitoring duration, the monitoring extension duration, the short DRX cycle duration, and the short DRX cycle number to the UE through the target DCI. The monitoring duration determined by the base station may be longer than the monitoring duration currently used by the UE, the monitoring extension duration determined by the base station may be longer than the monitoring extension duration currently used by the UE, the base station may configure a short DRX cycle duration for the UE when the UE currently uses the long DRX cycle duration, and the number of short DRX cycles determined by the base station may be longer than the number of short DRX cycles currently used by the UE.

For another example, when it is monitored that the communication traffic data amount of the UE decreases and the decreased amount is greater than the second amplitude threshold, or when it is monitored that the communication traffic data amount of the UE decreases and the decreased communication traffic data amount is less than the second data amount threshold, the base station may determine at least one of the monitoring duration, the monitoring extension duration, the long DRX cycle duration, and the short DRX cycle number according to the decreased amount of the communication traffic data amount of the UE, and indicate the at least one of the monitoring duration, the monitoring extension duration, the long DRX cycle duration, and the short DRX cycle number to the UE through the target DCI. The monitoring duration determined by the base station may be less than the monitoring duration currently used by the UE, the monitoring extension duration determined by the base station may be less than the monitoring extension duration currently used by the UE, the base station may configure a long DRX cycle duration for the UE when the UE currently uses a short DRX cycle duration, and the number of short DRX cycles determined by the base station may be less than the number of short DRX cycles currently used by the UE.

For another example, since the data volume of the communication service of the UE is related to the type of the communication service performed by the UE, for example, when the UE performs a video playing type communication service, the data volume of the communication service is large. Therefore, in the embodiment of the present disclosure, if it is monitored that the type of the communication service performed by the UE changes, the base station may determine at least one of the monitoring duration, the monitoring extension duration, the long DRX cycle duration, the short DRX cycle duration, and the short DRX cycle number according to the changed type of the communication service, and indicate the at least one of the monitoring duration, the monitoring extension duration, the long DRX cycle duration, the short DRX cycle duration, and the short DRX cycle number to the UE through the target DCI.

It should be noted that the first amplitude threshold, the second amplitude threshold, the first data volume threshold, and the second data volume threshold may be specified by a communication protocol, or may be determined by the base station itself, which is not specifically limited in the embodiment of the present disclosure.

It should be further noted that, when it is monitored that the communication service data volume of the UE does not change, or when it is monitored that the communication service data volume of the UE changes but the change amplitude does not satisfy the preset condition, the base station may indicate the DRX parameter currently used by the UE to the UE through the target DCI, or the base station may not send the target DCI to the UE.

Hereinafter, the data structure of the target DCI will be briefly described in the embodiments of the present disclosure.

In a first possible implementation manner, the wireless communication system may introduce DCI of a new format (english: format), where the DCI of the new format refers to a DCI format different from any DCI format defined by the LTE communication system, and the DCI of the new format is used to indicate the DRX parameter, and the DCI of the new format is the target DCI described above. For convenience of explanation, only the DCI of the new format is hereinafter referred to as the first target format.

In such implementations, the targeted DCI may include one or more of a monitor duration indication field, a monitor extended duration indication field, a long DRX cycle duration indication field, a short DRX cycle duration indication field, and a short DRX cycle number indication field. Referring to fig. 6, the exemplary target DCI shown in fig. 6 may include a monitoring duration indication field, a monitoring extension duration indication field, a long DRX cycle duration indication field, a short DRX cycle duration indication field, and a short DRX cycle number indication field.

The monitoring duration indication domain is used for bearing monitoring duration indication information, and the monitoring duration indication information is used for indicating monitoring duration; the monitoring extension duration indication domain is used for bearing monitoring extension duration indication information, and the monitoring extension duration indication information is used for indicating monitoring extension duration; the long DRX cycle duration indication domain is used for bearing long DRX cycle duration indication information, and the long DRX cycle duration indication information is used for indicating the long DRX cycle duration; the short DRX cycle duration indication domain is used for bearing short DRX cycle duration indication information, and the short DRX cycle duration indication information is used for indicating the short DRX cycle duration; the short DRX cycle number indication domain is used for carrying short DRX cycle number indication information, and the short DRX cycle number indication information is used for indicating the short DRX cycle number.

In the embodiment of the present disclosure, the monitoring duration indication information, the monitoring extension duration indication information, the long DRX cycle duration indication information, the short DRX cycle duration indication information, and the short DRX cycle duration indication information may be collectively referred to as parameter indication information.

Optionally, the parameter indication information may be a value of a DRX parameter, and take the monitoring duration indication information as an example, the monitoring duration indication information may occupy 4 bits, for example, the monitoring duration indication information may be 1000 (i.e., is a binary representation of 8).

Optionally, the parameter indication information may be an identification value, where the identification value is used to indicate a DRX parameter in the target parameter set, taking the monitoring duration indication information as an example, the monitoring duration indication information may occupy 2 bits, the target parameter set may include 4 monitoring durations, and the 4 monitoring durations may be 3,40, 10, and 80, for example, when the monitoring duration indication information is 10, the monitoring duration indication information indicates a 2 nd monitoring duration value in the target parameter set, that is, 40.

It should be noted that the DRX parameter in the target parameter set may be selected by the base station, and after the DRX parameter is selected by the base station, the base station may send the target parameter set to the UE through high-level signaling; the DRX parameter in the target parameter set may also be specified by a communication protocol, which is not specifically limited in this disclosure.

In a wireless communication system, in order to reduce the number of blind detections for a PDCCH by a UE, it is generally required to ensure that DCIs of different formats (english: format) have the same data length. Therefore, when target DCI of a new format is introduced into a wireless communication system, it is necessary to ensure that the data length of the target DCI is equal to the data length of DCI of another format.

In order to achieve the above object, in a case that the data length of the parameter indication information is smaller than the data length of the DCI specified by the communication protocol, the embodiments of the present disclosure may add a padding data segment to the target DCI to ensure that the data length of the target DCI is equal to the data length of the DCI of another format, that is, equal to the data length of the DCI specified by the communication protocol.

In the embodiment of the present disclosure, in order to enable the UE to identify the target DCI, and then parse the parameter indication information from the target DCI after identifying the target DCI, the target DCI may carry the DCI type indication information, or the base station may scramble a Cyclic Redundancy Check value (CRC) of the target DCI using a target Radio Network Temporary Identity (RNTI).

Referring to fig. 7, as shown in fig. 7, a type information indication field may be further included in the target DCI, where the type information indication field is used to carry DCI type indication information, and the DCI type indication information is used to indicate the first target format. In this way, after receiving the target DCI, the UE may obtain the DCI type indication information by analyzing the target DCI, and then may recognize that the received target DCI is the DCI indicating the DRX parameter through the DCI type indication information. Alternatively, the DCI type indication information may occupy one bit.

Referring to fig. 8, as shown in fig. 8, a base station may scramble the CRC of the target DCI using a target RNTI, where the target RNTI is used to indicate the first target format. When the UE performs blind detection on the PDCCH, the UE may attempt to descramble DCI carried on the PDCCH using the target RNTI, and if the UE uses the target RNTI to descramble a certain DCI successfully, the UE may determine that the certain DCI is the target DCI, that is, the certain DCI is the DCI indicating the DRX parameter.

In a second possible implementation manner, the embodiment of the present disclosure may modify the existing DCI, so that the existing DCI can implement the indication of the DRX parameter, in this case, the modified existing DCI is the target DCI, where the format of the target DCI is the second target format, and the second target format is a format specified by the LTE communication system.

Optionally, in the embodiment of the present disclosure, a DRX parameter indication field may be added to an existing DCI, and the DRX parameter indication field may carry the parameter indication information.

The parameter indication information may be one or more of monitoring duration indication information, monitoring extension duration indication information, long DRX cycle duration indication information, short DRX cycle duration indication information, and short DRX cycle number indication information. In other words, the parameter indication information carried on the DRX parameter indication field may indicate a target type of DRX parameters, where the target type may be one or more of a monitoring duration type, a monitoring extended duration type, a long DRX cycle duration type, a short DRX cycle duration type, and a short DRX cycle number type.

In the embodiment of the present disclosure, the target type may be specified by a communication protocol or may be determined by the base station itself. Under the condition that the base station determines the target type by itself, the DRX parameter indication field may further carry parameter type indication information, where the parameter type indication information is used to indicate a type of DRX parameters indicated by the parameter indication information carried in the DRX parameter indication field, that is, the parameter type indication information is used to indicate the target type.
