Technical Field

Background

A Physical Downlink Control Channel (PDCCH) is a Channel for carrying Downlink Control Information (DCI). The DCI transmitted by the base station to a certain User Equipment (UE) through the PDCCH may be used to schedule the UE.

Because the UE cannot predict when the base station will issue the DCI, in the related art, the UE needs to monitor the PDCCH according to a fixed monitoring period, for example, the UE may determine a target subframe every 3 subframes and monitor the PDCCH in the target subframe, the base station may send the DCI to the UE through the PDCCH that the UE needs to monitor, and when the UE receives the DCI sent by the base station on a certain PDCCH that needs to be monitored, the UE may respond to the scheduling of the base station according to the DCI.

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 usually predict the DCI sending time of the base station, the UE needs to monitor the PDCCH in real time so as to receive the DCI sent by the base station in time.

In one possible implementation, 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, the PDCCHs in most subframes do not carry the DCI transmitted by the base station to the UE, 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, in the related art, the UE may monitor the PDCCH at a fixed period, for example, the UE may determine a target subframe every 3 subframes and monitor the PDCCH in the target subframe. In order to ensure that the UE can successfully receive the DCI, the base station may determine a subframe in which a PDCCH that the UE needs to monitor is located, and send the DCI to the UE through any PDCCH that the UE needs to monitor.

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 traffic data volume of the UE is intensively exploded, the base station needs to transmit a large amount of DCI to the UE. In the related art, since the base station can transmit DCI to the UE only through the PDCCH that the UE needs to monitor, when a large amount of DCI needs to be transmitted, the time delay for the base station to transmit DCI to the UE is large. For example, in the case that the base station can only transmit DCI to the UE through the PDCCH in the target subframe illustrated above, since there are 3 subframes between two adjacent target subframes, if 3 DCIs are to be transmitted to the UE, the base station needs to pass the time length of 9 subframes to completely transmit the 3 DCIs to the UE, and the time delay is large.

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, and at this time, a situation that most of the PDCCHs monitored by the UE do not carry the DCI sent by the base station to the UE may occur, which may cause a certain waste to the power consumption of the UE, thereby affecting the standby time of the UE.

Therefore, in the related art, it is difficult for the UE to adapt to the dynamically changing traffic data volume in a manner of monitoring the PDCCH at a fixed period, and the flexibility 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, in the process that the UE monitors the PDCCH according to a certain monitoring period, the base station may indicate a second monitoring period to the UE, so that the UE monitors the PDCCH according to the second monitoring period. Therefore, the base station can control the period of PDCCH monitoring of the UE in the process that the PDCCH is monitored by the UE, so that the flexibility of PDCCH monitoring of the UE can be improved.

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

Fig. 1 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. 1, 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) Communication network, or another Communication network similar to The LTE Communication network or The 5G Communication network.

Fig. 2 is a flowchart illustrating a channel monitoring method according to an exemplary embodiment, which is used in the UE20 shown in fig. 1, as shown in fig. 2, and includes the following steps:

step 201, in the process of monitoring the PDCCH according to the first monitoring period, the UE acquires a second monitoring period according to the indication of the base station.

Step 202, the UE monitors the PDCCH according to the second monitoring period.

To sum up, in the channel monitoring method provided by the embodiment of the present disclosure, in the process of monitoring the PDCCH according to the first monitoring period, the second monitoring period is obtained according to the indication of the base station, and the PDCCH is monitored according to the second monitoring period, so that the base station can control the period of monitoring the PDCCH by the UE in the process of monitoring the PDCCH by the UE, thereby improving the flexibility of monitoring the PDCCH by the UE.

Fig. 3 is a flowchart illustrating a channel monitoring method according to an exemplary embodiment, which is used in the base station 10 shown in fig. 1, and includes the following steps:

step 301, in the process that the UE monitors the PDCCH according to the first monitoring period, the base station indicates a second monitoring period to the UE.

And the UE is configured to acquire a second monitoring period according to the indication of the base station and monitor the PDCCH according to the second monitoring period.

To sum up, according to the channel monitoring method provided by the embodiment of the present disclosure, in the process that the UE monitors the PDCCH according to the first monitoring period, the UE is instructed to the second monitoring period, so that the UE can obtain the second monitoring period according to the instruction of the base station, and monitor the PDCCH according to the second monitoring period, and thus, the base station can control the period of monitoring the PDCCH by the UE in the process that the UE monitors the PDCCH, thereby improving the flexibility of monitoring the PDCCH by the UE.

Fig. 4 is a flow chart illustrating a channel monitoring method according to an exemplary embodiment, the channel monitoring method being used in the implementation environment shown in fig. 1, as shown in fig. 4, and the channel monitoring method including the steps of:

step 401, in the process that the UE monitors the PDCCH according to the first monitoring period, the base station indicates a second monitoring period to the UE.

Wherein, the monitoring period for monitoring the PDCCH by the UE refers to: the time unit of any two adjacent PDCCHs in the PDCCHs to be monitored by the UE may be a subframe, a time slot, a symbol, or the like. For example, if the UE needs to monitor the PDCCH in the target subframe, the time interval between any two adjacent target subframes in the time domain is the monitoring period for the UE to monitor the PDCCH.

In a possible implementation manner, the monitoring period for the UE to monitor the PDCCH may be characterized by a duration, for example, the monitoring period for the UE to monitor the PDCCH may be 3 ms. In another possible implementation manner, the monitoring period for the UE to monitor the PDCCH may be represented by the number of subframes, for example, the monitoring period for the UE to monitor the PDCCH may be 3 subframes. The embodiment of the present disclosure does not specifically limit the characterization manner of the monitoring period.

Optionally, in the process that the UE monitors the PDCCH according to the first monitoring period, the base station may monitor a change of a communication service data volume of the UE. If the communication service data volume of the UE is monitored to change, and the change amplitude meets the preset condition, the base station may determine the second monitoring period according to the change condition of the communication service data volume of the UE. Then, the base station can indicate the second monitoring period to the UE, so that the UE monitors the PDCCH according to the second monitoring period, the monitoring of the PDCCH by the UE can adapt 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, in the process that the UE monitors the PDCCH according to the first monitoring period, if it is monitored that the communication service data volume of the UE increases and the increased amplitude is greater than the first amplitude threshold, the base station may determine the second monitoring period according to the increased amplitude of the communication service data volume of the UE. Then, the base station may indicate the second monitoring period to the UE, so that the UE monitors the PDCCH according to the second monitoring period, in which case the second monitoring period may be smaller than the first monitoring period.

For another example, in the process that the UE monitors the PDCCH according to the first monitoring period, if it is monitored that the communication service data volume of the UE decreases and the decrease range is greater than the second range threshold, the base station may determine the second monitoring period according to the decrease range of the communication service data volume of the UE. Then, the base station may indicate the second monitoring period to the UE, so that the UE monitors the PDCCH according to the second monitoring period, in which case the second monitoring period may be greater than the first monitoring period.

For another example, since the size of the communication service data volume 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, in the process that the UE monitors the PDCCH according to the first monitoring period, if it is monitored that the type of the communication service performed by the UE changes, the base station may determine the second monitoring period according to the changed type of the communication service. Then, the base station may indicate the second monitoring period to the UE, so that the UE monitors the PDCCH according to the second monitoring period.

It should be noted that the first amplitude threshold and the second amplitude threshold may be defined by a communication protocol, or may be determined by the base station itself, and the embodiment of the present disclosure does not specifically limit the threshold.

In an embodiment of the present disclosure, the base station may periodically monitor a change of the communication service data amount of the UE, and when it is monitored that the communication service data amount of the UE changes and the change amplitude satisfies a preset condition, the base station may determine a second monitoring period according to the change of the communication service data amount of the UE as described above, and indicate the second monitoring period to the UE; 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 determine the first monitoring period as the second monitoring period and indicate the second monitoring period to the UE, or the base station may not indicate the UE.

In a possible implementation manner, the manner in which the base station indicates the second monitoring period to the UE may be: and the base station inquires a corresponding relation set according to the second monitoring period, wherein the corresponding relation set comprises at least one corresponding relation between the indication information and the monitoring period, the base station obtains target indication information corresponding to the second monitoring period from the corresponding relation set after inquiry, and then the base station indicates the target indication information. The corresponding relationship set may be specified by a communication protocol or determined by the base station itself, and when the corresponding relationship set is determined by the base station itself, the base station may send the corresponding relationship set to the UE through a high-level signaling before indicating the second monitoring period.

In this embodiment of the present disclosure, the indication information may be a Radio Network Temporary Identity (RNTI), a search space position, monitoring period information, and the like, where the search space position may be a position of a Control Channel Element (CCE) where DCI is located in a PDCCH.

In practical implementation, the base station may indicate the second monitoring period to the UE through the PDCCH, or may indicate the second monitoring period to the UE through a non-PDCCH channel, and in the following, the embodiment of the present disclosure will further explain a manner in which the base station indicates the second monitoring period to the UE for these two cases:

in the first case, the base station indicates the second monitoring period to the UE through the PDCCH, where the PDCCH is a PDCCH that needs to be monitored when the UE monitors the PDCCH according to the first monitoring period.

In this case, the embodiment of the present disclosure will describe, for three cases that the indication information is the monitoring period information, the RNTI, and the search space position, a manner in which the base station indicates the second monitoring period to the UE through the PDCCH:

1. when the indication information is monitoring period information, the manner in which the base station indicates the second monitoring period to the UE through the PDCCH may be:

the base station queries the corresponding relation set according to the second monitoring period, and after querying, the base station obtains first monitoring period information corresponding to the second monitoring period from the corresponding relation set, where the first monitoring period information is the target indication information. Then, the base station transmits the first DCI to the UE through the first PDCCH.

The first DCI may include a period indication field, where the period indication field may carry the first monitoring period information, and the first PDCCH is any PDCCH that needs to be monitored by the UE when monitoring the PDCCH according to the first monitoring period.

In this way, the above-mentioned correspondence set may be as shown in table 1 below:

TABLE 1

Monitoring period indication information	Monitoring period
		00	T1
01	T2
		10	T3
11	T4

As shown in table 1, when the second monitoring period is T2, the first monitoring period information may be 01. Of course, the illustration in table 1 is merely exemplary and is not intended to limit the scope of the present disclosure.

2. When the indication information is the RNTI, the manner in which the base station indicates the second monitoring period to the UE through the PDCCH may be:

and the base station inquires the corresponding relation set according to the second monitoring period, and after inquiry, the base station obtains the target RNTI corresponding to the second monitoring period from the corresponding relation set, wherein the target RNTI is the target indication information. The base station scrambles the second DCI by using the target RNTI, and optionally, the base station may scramble a Cyclic Redundancy Check (CRC) of the second DCI by using the target RNTI. And then, the base station sends the scrambled second DCI to the UE through the second PDCCH.

The second PDCCH is any PDCCH that the UE needs to monitor when monitoring the PDCCH according to the first monitoring period, and as an example, the second PDCCH may be a PDCCH in any target subframe.

When the indication information is RNTI, the correspondence relationship may be as shown in table 2 below:

TABLE 2

RNTI	Monitoring period
		RNTI 1	T1
RNTI 2	T2
		RNTI 3	T3
RNTI 4	T4

As shown in table 2, when the second monitoring period is T2, the target RNTI may be RNTI 2. Of course, the illustration in table 2 is merely exemplary and is not intended to limit the scope of the present disclosure.

3. When the indication information is the search space position, the manner in which the base station indicates the second monitoring period to the UE through the PDCCH may be:

the base station queries the corresponding relation set according to the second monitoring period, and after querying, the base station obtains a target search space position corresponding to the second monitoring period from the corresponding relation set, where the target search space position is the target indication information. And then, the base station maps the third DCI to a target search space position of a third PDCCH, and transmits the third DCI to the UE through the third PDCCH.

The third PDCCH is any PDCCH that the UE needs to monitor when monitoring the PDCCH according to the first monitoring period, and as an example, the third PDCCH may be a PDCCH in any target subframe.

When the indication information is a search space position, the correspondence relationship may be as shown in table 3 below:

TABLE 3

Searching spatial locations	Monitoring period
		CCE location 1	T1
CCE location 2	T2
		CCE location 3	T3
CCE location 4	T4

As shown in table 3, when the second monitoring period is T2, the target search space position may be CCE position 2. Of course, the illustration in table 3 is merely exemplary and is not intended to limit the scope of the present disclosure.

In the second case, the base station indicates the second monitoring period to the UE through a non-PDCCH channel, where the non-PDCCH channel may be a downlink channel newly defined by a communication protocol or an existing downlink channel, and for convenience of description, the "non-PDCCH channel" is referred to as a "target downlink channel" in the embodiments of the present disclosure.

When the base station indicates the second monitoring period to the UE through the non-PDCCH channel, the indication information may be monitoring period information.

The base station may query the corresponding relationship set according to the second monitoring period, and after the query, the base station may obtain second monitoring period information corresponding to the second monitoring period from the corresponding relationship set, where the second monitoring period information is the target indication information. And then, the base station sends second monitoring period information to the UE through the first target downlink channel.

The target downlink channel is a downlink channel different from the PDCCH, and similarly to monitoring the PDCCH, the UE may periodically monitor the target downlink channel (the monitoring period may be a third monitoring period), where the first target downlink channel is any target downlink channel that needs to be monitored when the UE monitors the target downlink channel according to the third monitoring period.

In an embodiment of the present disclosure, the third monitoring period may be configured by the base station for the UE through high layer signaling.

In one embodiment of the present disclosure, the second monitoring period information may occupy at least one bit, or the second monitoring period information may be a sequence.

In a case where the second monitoring period information occupies at least one bit, the correspondence set may be the same as that shown in table 1, and in a case where the second monitoring period information is a sequence, the correspondence may be as shown in table 4 below:

TABLE 4

Monitoring a periodic indication sequence	Monitoring period
		Sequence 1	T1
Sequence 2	T2
		Sequence 3	T3
Sequence 4	T4

As shown in table 4, when the second monitoring period is T2, the second monitoring period information may be sequence 2. Of course, the illustration in table 4 is merely exemplary and is not intended to limit the scope of the present disclosure.

It should be noted that the first monitoring period described above may be a period used when the UE initially monitors the PDCCH, or may not be a period used when the UE initially monitors the PDCCH.

When the first monitoring period is not a period used when the UE initially monitors the PDCCH, the first monitoring period may be a monitoring period indicated by the base station when the UE monitors the PDCCH according to the fourth monitoring period. In this case, the manner of indicating the first monitoring period by the base station is the same as the manner of indicating the second monitoring period by the base station described above, and details of the embodiment of the present disclosure are not repeated herein.

When the first monitoring period is a period used when the UE initially monitors the PDCCH, the base station may send a period set to the UE through a high-level signaling in advance, where the period set includes at least one monitoring period, and the UE may store the period set to a local location after receiving the period set. The base station may indicate one monitoring period in the period set (for example, indicate one monitoring period in the period set through a high-level signaling) when the UE initially monitors the PDCCH, where the indicated monitoring period is a first monitoring period, and may indicate a second subframe, where the second subframe is a first subframe that needs to be monitored when the UE initially monitors the PDCCH. The UE may obtain the first monitoring period from the period set according to the indication of the base station, and meanwhile, the UE may obtain the second subframe according to the indication of the base station. Then, the UE may monitor the PDCCH with the PDCCH in the second subframe as a monitoring starting point according to the first monitoring period.

Step 402, the UE obtains a second monitoring period according to the indication of the base station.

Corresponding to the manner in which the base station indicates the second monitoring period, the following describes a manner in which the UE acquires the second monitoring period according to the indication of the base station:

in a possible implementation manner, the UE may obtain the target indication information according to the indication of the base station, and then, the UE may query the corresponding relationship set according to the target indication information, and after the query, the UE may obtain the monitoring period corresponding to the target indication information from the corresponding relationship set, and obtain the monitoring period corresponding to the target indication information as the second monitoring period. The UE may receive the corresponding relationship set sent by the base station through the high-level signaling before the base station indicates the second monitoring period when the corresponding relationship set is determined by the base station itself, and store the received corresponding relationship set locally.

First, in a case where a base station indicates a second monitoring period to a UE through a PDCCH, the embodiment of the present disclosure explains a manner in which the UE acquires the second monitoring period according to an indication of the base station, for three cases where the indication information is monitoring period information, an RNTI, and a search space position:

1. when the indication information is monitoring period information, the manner of acquiring the second monitoring period by the UE according to the indication of the base station may include the following two manners:

the UE receives a first DCI sent by the base station through the first PDCCH, and acquires first monitoring period information from a period indication domain of the first DCI, where the first monitoring period information is the target indication information. Then, the UE may obtain a second monitoring period according to the first monitoring period information, optionally, the UE may query a corresponding relationship set shown in table 1 according to the first monitoring period information, and after the query, the UE obtains the monitoring period corresponding to the first monitoring period information from the corresponding relationship set, and obtains the monitoring period corresponding to the first monitoring period information as the second monitoring period.

2. When the indication information is the RNTI, the manner of acquiring the second monitoring period by the UE according to the indication of the base station may be:

the UE obtains an RNTI set, where the RNTI set may include at least one RNTI, and the RNTI set may be issued by a base station in advance through a high-level signaling or may be specified by a communication protocol. And then, the UE descrambles the DCI carried by the second PDCCH sequentially by using the RNTI in the RNTI set, and optionally, the UE may descramble the CRC of the DCI carried by the second PDCCH sequentially by using the RNTI in the RNTI set. When the UE descrambles a DCI carried by the second PDCCH with a RNTI in the RNTI set successfully, it indicates that the DCI is a DCI transmitted by the base station to the UE, the DCI is the second DCI, the RNTI is the target RNTI, and the target RNTI is the target indication information.

Then, the UE may obtain the second monitoring period according to the target RNTI, optionally, the UE may query the corresponding relationship set shown in table 2 according to the target RNTI, and after the query, the UE may obtain the monitoring period corresponding to the target RNTI from the corresponding relationship set, and obtain the monitoring period corresponding to the target RNTI as the second monitoring period.

3. When the indication information is the search space position, the manner of acquiring the second monitoring period by the UE according to the indication of the base station may be:

and the UE determines the target search space position where the third DCI sent to the UE by the base station through the third PDCCH is located, wherein the target search space position is the target indication information. Then, the UE may obtain a second monitoring period according to the target search space position, optionally, the UE may query a corresponding relationship set shown in table 3 according to the target search space position, and after the query, the UE may obtain the monitoring period corresponding to the target search space position from the corresponding relationship set, and obtain the monitoring period corresponding to the target search space position as the second monitoring period.

Second, in a case where the base station indicates the second monitoring period to the UE through the non-PDCCH channel, the embodiment of the present disclosure explains, for a case where the indication information is monitoring period information, a manner in which the UE acquires the second monitoring period according to the indication of the base station:

and the UE monitors the target downlink channels according to the third monitoring period, and when receiving second monitoring period information (the second monitoring period information is the target indication information) sent by the base station in any monitored target downlink channel, acquires the second monitoring period according to the second monitoring period information. Optionally, the UE may query a corresponding relationship set shown in table 1 or table 4 according to the second monitoring period information, and after the query, the UE obtains the monitoring period corresponding to the second monitoring period information from the corresponding relationship set, and obtains the monitoring period corresponding to the second monitoring period information as the second monitoring period.

And step 403, the UE monitors the PDCCH according to the second monitoring period.

When the base station indicates the second monitoring period through the PDCCH, the UE may monitor the PDCCH according to the second monitoring period in the following manner:

and the UE determines a third subframe and monitors the PDCCH by taking the PDCCH in the third subframe as a monitoring starting point according to a second monitoring period. And the third subframe is positioned behind the target sending time in the time domain and is separated from the target sending time in the time domain by the target time length.

The target sending time is a time when the UE sends a target Hybrid Automatic Repeat Request (HARQ), and the target HARQ is used to indicate that the UE successfully obtains the second monitoring period according to the indication of the base station.

It should be noted that the target duration may be specified by a communication protocol, or may be configured by the base station for the UE, which is not specifically limited in this disclosure.

Referring to fig. 5, as shown in fig. 5, a base station indicates a second monitoring period to a UE through a PDCCH in a subframe 1, where the PDCCH in the subframe 1 is one PDCCH that the UE needs to monitor when monitoring the PDCCH according to a first monitoring period t1, after the second monitoring period is successfully acquired according to the indication of the base station, the UE transmits a target HARQ to the base station at a time 1, where the time 1 is a target transmission time, and a subframe 2 is located after the time 1 in a time domain and is separated from the time 1 by a target duration t2 in the time domain, so that the UE may acquire the subframe 2 as a third subframe, and then the UE may monitor the PDCCH with the PDCCH in the subframe 2 as a monitoring start point according to a second monitoring period t 3.

When the base station indicates the second monitoring period through the non-PDCCH channel, the UE may monitor the PDCCH according to the second monitoring period in the following manner:

and the UE determines a first subframe and monitors the PDCCH by taking the PDCCH in the first subframe as a monitoring starting point according to a second monitoring period. And the first subframe is positioned behind the target downlink channel carrying the second monitoring period information in the time domain, and the time length of the first subframe from the target downlink channel carrying the second monitoring period information in the time domain is less than a target time length threshold value.

It should be noted that the target duration threshold may be specified by a communication protocol, or may be configured by the base station for the UE, which is not specifically limited in this disclosure.

Referring to fig. 6, as shown in fig. 6, the base station sends second monitoring period information to the UE through the target downlink channel in the subframe 3, where the target downlink channel in the subframe 3 is a target downlink channel that needs to be monitored when the UE monitors the target downlink channel according to a third monitoring period t4, the subframe 4 is located behind the target downlink channel in the subframe 3 in the time domain, and a time t5 that is away from the target downlink channel in the subframe 3 in the time domain is less than a target time threshold, the UE may acquire the subframe 4 as a first subframe, and then the UE may monitor the PDCCH with the PDCCH in the subframe 4 as a monitoring start point according to a second monitoring period t 3.

It should be noted that, since the base station needs to transmit DCI to the UE on the PDCCH monitored by the UE, the base station needs to determine the location of the PDCCH monitored by the UE. In order to achieve this purpose, after indicating the second monitoring period to the UE, the base station needs to determine a starting point at which the UE monitors the PDCCH according to the second monitoring period, in other words, the base station needs to determine the third subframe and the first subframe, where a manner in which the base station determines the third subframe and the first subframe is the same as a manner in which the UE determines the third subframe and the first subframe, and details of the embodiments of the present disclosure are not repeated here.
