Background

In a Radio Resource Control (RRC) connected state, a terminal needs to periodically monitor Downlink Control Information (DCI) sent to the terminal by an access network device under configuration of a Physical Downlink Control Channel (PDCCH) search space.

However, a large amount of power consumption of the terminal in the RRC connected state is wasted. Such as: the terminal periodically monitors the PDCCH every several subframes based on the configuration of the PDCCH Search Space, but the access network equipment actually only sends DCI to the terminal on a small number of PDCCH transmission time slots, and does not have the DCI for the terminal on the rest of a large amount of time, thereby wasting the power consumption of the terminal.

Detailed Description

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

Fig. 1 is a schematic environment for implementing a listening method of a physical downlink control channel according to an exemplary embodiment of the present application. The implementation environment may include user equipment 140 and access network equipment 120, with access network equipment 120 including at least one base station (only one base station is shown in fig. 1). Optionally, at least one base station may be a macro base station or a micro base station.

In the uplink scenario, the user equipment 140 performs data transmission on the PUSCN according to the second DCI sent by the access network equipment 120; the second DCI is for scheduling a valid PUSCN.

In a downlink scenario, the access network device 120 sends the first DCI to the user equipment 140, and the user equipment 140 receives the first DCI sent by the access network device 120 and monitors according to the first DCI by using the first PDCCH monitoring configuration; or, the access network device 120 sends the second DCI to the user equipment, and the user equipment 140 receives the second DCI sent by the access network device 120, and monitors according to the second DCI by using the second PDCCH monitoring configuration.

Alternatively, the user device 140 may be a mobile terminal such as a mobile telephone (or "cellular" telephone) and a device having mobile communication capabilities, for example, the user device 140 may be a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile terminal. The user equipment 140 may have different names in different mobile communication networks. Such as: a Mobile Station (Mobile Station), a Mobile Station (Mobile), an Access Terminal (Access Terminal), a User Equipment (User Terminal), a User Agent (User Agent), and a User Terminal (User Equipment).

In an exemplary communication system, the access network device may pre-configure up to 16 time frequency resources for PDSCH and PUSCH through higher layer signaling (system broadcast or RRC dedicated signaling), each time frequency resource including a data channel start time offset (K)₀Or K₂) A starting symbol S and a length L. When the access network device schedules the terminal, one of the 16 resource configurations is indicated by the DCI to serve as the time-frequency resource actually used in the transmission. Wherein, K₀Is PDSCH starting time offset, K₂Is the PUSCH start time offset.

In addition to the resource indication function of the DCI itself, in this embodiment of the present application, the access network device further provides two different PDCCH monitoring configurations to the terminal, and implicitly triggers the terminal to switch between two PDCCH monitoring modes by using the DCI. Optionally, the DCI for triggering the listening mode switch includes: and the first DCI conforming to the first indication mode and the second DCI conforming to the second indication mode.

As shown in fig. 2 and/or fig. 4, when the DCI is a first DCI, the first DCI is used to instruct the terminal to perform PDCCH monitoring using a first PDCCH monitoring configuration;

as in fig. 7 and/or fig. 8, when the DCI is the second DCI, the second DCI is used to instruct the terminal to perform PDCCH monitoring in the second PDCCH monitoring configuration.

Fig. 2 is a flowchart of a monitoring method for PDCCH according to an exemplary embodiment of the present application, and the method is applied to the implementation environment shown in fig. 1, for example, the method may include:

in step 201, an access network device determines a first PDCCH monitoring configuration and a second PDCCH monitoring configuration.

The monitoring period of the first PDCCH monitoring configuration is longer than that of the second PDCCH monitoring configuration. Optionally, a monitoring period of the first PDCCH monitoring configuration is equivalent to i times a monitoring period of the second PDCCH monitoring configuration, where i is a positive integer greater than 1.

In a first possible implementation, the first PDCCH monitoring configuration and the second PDCCH monitoring configuration are predefined (Pre-determined) in a communication protocol.

In a second possible implementation, the first PDCCH monitoring configuration and the second PDCCH monitoring configuration are Pre-configured (Pre-configured) by the access network device. And the access network equipment informs the terminal of the first PDCCH monitoring configuration and the second PDCCH monitoring configuration which are dynamically determined. Optionally, the access network device informs the terminal of the first PDCCH monitoring configuration and the second PDCCH monitoring configuration in a system broadcast manner; or the access network equipment determines the first PDCCH monitoring configuration and the second PDCCH monitoring configuration to the terminal through RRC dedicated signaling.

In a third possible implementation, the first PDCCH monitoring configuration is preconfigured by the access network device, and the second PDCCH monitoring configuration is predefined in the communication protocol. Optionally, the access network device informs the terminal of the first PDCCH monitoring configuration in a system broadcast manner; or, the access network device determines the first PDCCH monitoring configuration to the terminal through RRC dedicated signaling.

In step 202, the terminal determines a first PDCCH monitoring configuration and a second PDCCH monitoring configuration.

Corresponding to the first possible implementation manner described above, the first PDCCH monitoring configuration and the second PDCCH monitoring configuration are predefined in the communication protocol.

Corresponding to the second possible implementation manner, the terminal receives a broadcast or RRC dedicated signaling sent by the access network device to obtain the first PDCCH monitoring configuration and the second PDCCH monitoring configuration. The configuration time of the two listening configurations may be the same or different.

Corresponding to the third possible implementation manner, the terminal receives a preconfigured first PDCCH monitoring configuration sent by the access network device, and the terminal obtains a predefined second PDCCH monitoring configuration in the communication protocol.

And if the second PDCCH monitoring configuration is the default normal monitoring configuration, the terminal monitors by using the second PDCCH monitoring configuration in the initial state.

Step 203, the access network equipment sends the DCI to the terminal.

The DCI is used for scheduling time-frequency resources by the terminal, wherein the time-frequency resources comprise frequency domain resources and/or time domain resources. Optionally, the DCI is configured to indicate a time-frequency resource used this time from the preconfigured 16 time-frequency resources.

The time-frequency resources are represented by a two-dimensional space, the abscissa represents the time domain, and the ordinate represents the frequency domain. In the schematic time-frequency Resource partitioning manner shown in fig. 3, a frequency domain may be partitioned according to Physical Resource Blocks (PRBs), a region indicated by a black frame is 1 PRB, and each PRB includes 12 subcarriers, such as subcarrier 1 to subcarrier 12; the time domain may be divided by subframes, each subframe including two slots (slots): slot 0 and slot 1, each slot comprising again 7 symbols, e.g. slot 0 comprises symbols 0 to 6; slot 0 and slot 1 are one subframe.

One subframe can be regarded as one time unit; or, a time slot may be considered a time unit; alternatively, one symbol may be considered as one time unit. In the embodiment of the present application, one time slot is taken as an example of one time unit.

Optionally, the access network device sends DCI to the terminal using the PDCCH. Optionally, the DCI is a first DCI conforming to the first indication mode. The first DCI is used for scheduling an invalid PDSCH or PUSCH so as to implicitly instruct the terminal to perform PDCCH monitoring with the first PDCCH configuration. The PDSCH is a shared channel for transmitting data to the terminal by the access network equipment in a downlink scene; the PUSCH is a shared channel for a terminal to transmit data to an access network device in an uplink scenario.

Step 204, the terminal receives the DCI sent by the access network device.

And the terminal receives the DCI sent by the access network equipment on the PDCCH channel. And then, the terminal detects whether the DCI received this time is the first DCI according to the indication mode type of the DCI.

Step 205, when the DCI is the first DCI conforming to the first indication mode, the terminal performs PDCCH monitoring using the first PDCCH monitoring configuration.

Optionally, the first indication manner is an indication manner for scheduling an invalid PDSCH or PUSCH.

In some possible implementations, the first indication manner includes: the value of the designated information field in the DCI is a target value, and/or the indication content of the designated information field is the target information content. Optionally, the specifying the information field includes: at least one of a Frequency domain resource allocation (Frequency domain resource allocation) information field, a Time domain resource allocation (Time domain resource allocation) information field, and a hybrid automatic repeat request process number (HARQ process number) information field. Optionally, the content of the indication for specifying the information field includes: data channel start time offset (K) determined from the value of the time domain resource allocation information field₀Or K₂) At least one of a data channel duration (L) and a data channel starting symbol position (S).

In some possible implementations, the first indication manner may include at least one of the following manners:

the value of the frequency domain resource allocation information field is a first target value, for example, the first target value is 0; the value of the time domain resource allocation information field is a second target value, for example, the second target value is 0000 or 1111; data channel start time offset (K) determined by the value of the time domain resource allocation information field₀Or K₂) Greater than or equal to a third target value or null, e.g., the third target value is infinity; the data channel duration determined by the value of the time domain resource allocation information field is empty or less than or equal to a fourth target value, for example, the fourth target value is 0; the data channel starting symbol position determined by the value of the time domain resource allocation information field is greater than or equal to a fifth target value or null, for example, when oneWhen the number of symbols in each time unit is 14 and the number is from 0 to 13, the fifth target value is 13; the value of the harq process number information field is a sixth target value, for example, the sixth target value is 0000 or 1111.

Optionally, the first indication mode includes: the format of the DCI is a target DCI format. The target DCI format is a subset of all DCI formats. Illustratively, the target DCI format includes at least one of DCI format0_ 0, DCI format 1_0, DCI format0_1, and DCI format 1_ 1.

In summary, in the monitoring method for the PDCCH provided in this embodiment, by determining the first PDCCH monitoring configuration and the second monitoring configuration, a monitoring period of the first PDCCH monitoring configuration is greater than a monitoring period of the second PDCCH monitoring configuration; a terminal receives DCI sent by access network equipment; when the DCI is first DCI which accords with the first indication mode, the terminal adopts the first PDCCH monitoring configuration to carry out PDCCH monitoring; because the monitoring period of the first PDCCH monitoring configuration is longer than that of the second PDCCH monitoring configuration, compared with the second PDCCH monitoring configuration, the monitoring frequency under the first PDCCH monitoring configuration is reduced, thereby reducing the power waste of the terminal in the process of receiving the PDCCH under the second PDCCH monitoring configuration and reducing the power consumption of the terminal.

Illustratively, the monitoring period of the second PDCCH monitoring configuration is an original monitoring period for the terminal to monitor the PDCCH, and when the terminal receives the first DCI, the first PDCCH monitoring configuration with the monitoring period being greater than the original monitoring period is adopted, so that the monitoring frequency for the terminal to monitor the PDCCH is reduced, which can reduce the power waste of the terminal in the process of receiving the PDCCH and reduce the power consumption of the terminal.

Fig. 4 is a flowchart of a monitoring method for a PDCCH according to another exemplary embodiment of the present application, and in an optional embodiment based on fig. 2, the step 203 is alternatively implemented as 2031, the step 204 is alternatively implemented as 2041, and the step 205 is alternatively implemented as 2051, which illustrates a PDCCH monitoring method when DCI is a first DCI, where the method may include the following working procedures:

Optionally, the time unit n includes at least one symbol, the symbol is a minimum unit of time-frequency resources, and n is a positive integer. In this embodiment, the time unit is exemplified as a time slot. The time unit n has a PDCCH channel, and the access network device sends a first DCI to the terminal on the PDCCH channel, where the first DCI is used to schedule an invalid PDSCH or PUSCH, so as to trigger the terminal to perform subsequent monitoring by using the first PDCCH monitoring configuration.

In some embodiments, the first indication comprises: the value of the frequency domain resource allocation information domain is a first target value. The frequency domain resource allocation information is location information of frequency domain resources allocated to the terminal for data transmission on the PDSCH or PUSCH indicated by the DCI. Illustratively, when the first target value is 0, the value of the frequency domain resource allocation information field is 0, which may indicate that the frequency domain resource that is not allocated to the terminal for data transmission on the PDSCH or the PUSCH belongs to an invalid frequency domain scheduling manner.

In some embodiments, the first indication comprises: and the value of the time domain resource allocation information domain is a second target value. The frequency domain resource allocation information is the location information of the time domain resource used by the terminal for data transmission on the PDSCH or PUSCH indicated by the DCI. Illustratively, the second target value (4 bits of information) is binary 0000 or 1111, which belongs to an invalid time-domain scheduling mode.

Illustratively, the time domain resource allocation information field may be allocated up to 14 groups of symbols, the first group being labeled 0, and the fourteenth group being labeled 13. A time domain resource allocation information field comprises S and L indicators SLIV, and the terminal can determine S and L according to the relation table of S/L/SLIV by the SLIV, wherein S is a data channel starting symbol, and L is the data channel duration with S as a starting point. Illustratively, referring to table 1, when SLIV is 0, S is determined to be 0, and L is determined to be 1; when SLIV is 14, determining that S is 0 and L is 2; when SLIV is 15, S is 1 and L is 2.

It should be noted that table 1 is only an exemplary illustration, and more descriptions about SLIV may refer to table 5.1.2.1-1 in the communication standard TS 38.214.

In some embodiments, the first indication comprises: and the data channel starting time offset determined by the value of the time domain resource allocation information domain is greater than or equal to a third target value or null. And when the third target value is infinity or 0, the method belongs to an invalid time domain scheduling mode.

In some embodiments, the first indication comprises: and the initial symbol position of the data channel determined by the value of the time domain resource allocation information domain is greater than or equal to a fifth target value or null.

Illustratively, the value of the harq process number information field is binary 0000 or 1111, which may indicate that no time domain resource is allocated on the PDSCH or PUSCH to the terminal for data retransmission, and belongs to an invalid time domain scheduling manner.

It should be noted that, since the DCI includes a plurality of information fields, other information fields may also be designed in a manner similar to the foregoing invalid scheduling manner, and details are not repeated here.

In some embodiments, the first indication further includes: the DCI format is a target DCI format, which is a proper subset of all DCI formats. Illustratively, the target DCI format includes at least one of DCI format0_ 0, DCI format 1_0, DCI format0_1, and DCI format 1_ 1.

The first indication method is an invalid scheduling method for PDSCH or PUSCH, and the various invalid scheduling methods may be arbitrarily combined, which is not limited in this embodiment.

Step 2041, the terminal receives the first DCI sent by the access network device in time unit n.

The terminal receives DCI in the PDCCH in time unit n.

In a possible implementation manner, the CRC of the DCI is scrambled using a Cell Radio-Network temporary Identifier (C-RNTI) of the terminal, and the terminal descrambles the CRC of the DCI through its own C-RNTI, so as to obtain each information field in the DCI.

When the indication mode of the DCI conforms to the first indication mode, the terminal determines that the DCI is the first DCI, and proceeds to step 2051.

In step 2051, the terminal performs PDCCH monitoring using the first PDCCH monitoring configuration from time unit n + k.

k is a non-negative integer and k is a preset value, or the time unit n + k is determined according to the first PDCCH monitoring configuration.

In some embodiments, k is a preset value for the terminal, for example, time unit n + k is a time unit separated by k time intervals after time unit n. For example, k is 0, referring to fig. 5, if the terminal receives the first DCI sent by the access network device in time unit 2, the terminal switches from the second PDCCH monitoring configuration to the first PDCCH monitoring configuration for monitoring from time unit 2, optionally, the monitoring period of the first PDCCH monitoring mode is T2, the monitoring period of the second PDCCH monitoring mode is T1, and T1 is smaller than T2.

In some embodiments, time unit n + k is the last listening time unit of the at least one first candidate time unit that is located after time unit n; at least one first candidate time unit is determined according to the first PDCCH monitoring configuration.

For example, as shown in fig. 6, it is assumed that the terminal performs monitoring using the second PDCCH monitoring configuration before receiving the first DCI, and monitors the first DCI in time unit 15, the terminal starts monitoring from the second PDCCH monitoring configuration to the first PDCCH monitoring configuration in time unit 16, and determines a monitoring period T4 according to the first PDCCH monitoring configuration, as shown in the upper part of fig. 6, time units 11 to 15 are monitoring time units determined according to the second PDCCH monitoring configuration, and time units 16 to 18 are monitoring time units determined according to the first PDCCH monitoring configuration. When the terminal receives the first DCI in time unit 15, time units 16 to 18 are first candidate time units, where time unit 16 is the latest time unit after time unit 15, and thus it is determined to perform PDCCH monitoring using the first PDCCH monitoring configuration from time unit 16.

In some other embodiments, more than two PDCCH monitoring positions are included in the same time unit (e.g. subframe or slot), and the time unit n + k is the time unit of the latest monitoring time position after the first monitoring time position in the at least one first candidate monitoring time position; at least one first candidate monitoring time position is determined according to the first PDCCH monitoring configuration; the first listening time position is a listening time position at which the first DCI is received. In one possible embodiment, the candidate listening time positions are determined in symbol units, the time units are determined in slot units, and listening time positions located in more than two different symbols may be included in the same slot.

Illustratively, a time unit may include more than two monitoring time positions, for example, a time unit 01 corresponding to the second PDCCH monitoring configuration includes two monitoring time positions, which are a monitoring time position 1 and a monitoring time position 2 according to a time sequence, the terminal receives the first DCI at the monitoring time position 1, switches from the second PDCCH monitoring configuration to the first PDCCH monitoring configuration, and determines to perform PDCCH monitoring using the first PDCCH monitoring configuration from the time unit 01 if a monitoring time position in a monitoring period of the first PDCCH monitoring configuration that is closest to the monitoring time position 1 is the monitoring time position 2. Or, the terminal receives the first DCI at the monitoring time position 2, and since the latest monitoring time position from the monitoring time position 2 is the monitoring time position 3, and the monitoring time position 3 is the monitoring time position in the time unit 02 in the monitoring period of the first PDCCH monitoring configuration, it is determined that the PDCCH monitoring is performed using the first PDCCH monitoring configuration from the time unit 02.

In summary, in the method provided in this embodiment, by determining the first PDCCH monitoring configuration and the second monitoring configuration, the monitoring period of the first PDCCH monitoring configuration is longer than the monitoring period of the second PDCCH monitoring configuration; a terminal receives DCI sent by access network equipment; when the DCI is first DCI which accords with the first indication mode, the terminal adopts the first PDCCH monitoring configuration to carry out PDCCH monitoring; because the monitoring period of the first PDCCH monitoring configuration is longer than that of the second PDCCH monitoring configuration, compared with the second PDCCH monitoring configuration, the monitoring frequency under the first PDCCH monitoring configuration is reduced, thereby reducing the power waste of the terminal in the process of receiving the PDCCH under the second PDCCH monitoring configuration and reducing the power consumption of the terminal.
