Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network device 12 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present invention, only the Base Station in the NR system is taken as an example, but does not limit the specific type of base station.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 12 to terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

As shown in fig. 2, an embodiment of the present invention provides a method for monitoring downlink information, which is applied to a terminal side, and includes:

step 21: first listening configuration information is received.

Wherein the first monitoring configuration information is related to monitoring the first PDCCH.

For example: the first listening configuration information may be configured per Bandwidth Part (per BWP).

Wherein the first listening configuration information comprises at least one of the following parameter items: listening time domain resources, a listening period, a listening offset value, a listening duration, a Downlink Control Information (DCI) format (DCI-format), a Radio Network Temporary Identity (RNTI), an aggregation level, a search space, and a Control Resource Set (CORESET).

Step 22: and monitoring the first PDCCH according to the first monitoring configuration information when the preset condition is met.

Wherein the preset condition comprises at least one of the following:

the first condition is as follows: the second PDCCH is not monitored.

Specifically, the case where the second PDCCH is not monitored includes: the second PDCCH is not monitored during a preset timer (timer) timing.

And a second condition: no Physical Downlink Shared Channel (PDSCH) is detected.

Wherein the PDSCH is scheduled by a second PDCCH or other PDCCH, or the PDSCH is semi-persistent scheduling (semi-persistent scheduling) signaling scheduled, or the PDSCH is scheduling-free. In addition, the PDSCH may also be associated with the first listening configuration information, for example, the time domain resource corresponding to the PDSCH is associated with the time domain resource indicated by the first listening configuration information. As shown in fig. 3, a time domain resource diagram of a method for monitoring downlink information is shown, where an offset value between a PDCCH monitoring position indicated by the first monitoring configuration information and a time domain position of a PDSCH is T (as shown by an arrow in fig. 3). The terminal can detect the PDSCH according to the indication of the network device (e.g., detect the PDSCH at the PDSCH detection position shown in the shaded area in the dashed-line frame of fig. 3), and if the PDSCH is not detected at the detection position, monitor the first PDCCH according to the first monitoring configuration information (e.g., monitor the first PDCCH at the PDCCH monitoring position shown in the solid white area in the dashed-line frame of fig. 3), thereby reducing the power consumption of the terminal caused by blind detection of the PDCCH, and achieving the power saving effect of the terminal. It should be noted that, in the embodiment of the present invention, one PDSCH may be associated with one or more first listening configuration information, for example, one time domain resource where the PDSCH is located may be associated with one or more time domain resources indicated by the first listening configuration information. In addition, one first listening configuration information may also be associated with one or more PDSCHs, for example, one time domain resource indicated by the first listening configuration resource may be associated with one or more time domain resources where the PDSCHs are located. In the embodiment of the present invention, fig. 3 only illustrates that the time domain resources where the PDSCH is located and the time domain resources indicated by the first monitoring configuration information are associated one by one, and other association relationships may also be applicable to the embodiment of the present invention.

Specifically, the condition that the PDSCH is not detected includes one of the following:

unsuccessfully demodulating the PDSCH, if the information in the PDSCH is unsuccessfully demodulated;

generating Negative Acknowledgement (NACK) information corresponding to the PDSCH, wherein the terminal generates an ACK after successfully demodulating the PDSCH and may feed back the ACK to the network device, and correspondingly, the terminal generates the NACK and may feed back the NACK to the network device when not successfully demodulating the PDSCH or detecting the PDSCH;

data (the data in the soft buffer of the correcting HARQ process not having received the decoded) in a Hybrid Automatic Repeat Request (HARQ) process buffer, wherein the HARQ process is corresponding to the PDSCH.

And (3) carrying out a third condition: indication information for activating the first listening configuration information is received.

Specifically, the receiving of the indication information for activating the first monitoring configuration information includes: and receiving a scheduling PDCCH or a non-scheduling PDCCH, wherein the scheduling PDCCH or the non-scheduling PDCCH carries indication information.

The terminal of the embodiment of the invention monitors the first PDCCH according to the first monitoring configuration information by receiving the first monitoring configuration information related to the first PDCCH and meeting the preset condition, so as to reduce the power consumption of the terminal caused by blind detection of the PDCCH, thereby achieving the effect of saving power of the terminal.

It should be added that, when the preset condition is met in step 22, the first PDCCH is monitored according to the first monitoring configuration information; otherwise, the PDCCH is not monitored according to the first monitoring configuration information, that is:

monitoring the first PDCCH without the first monitoring configuration information when the preset condition is not met; or when the preset condition is not met, the first monitoring configuration information does not take effect; or, when the preset condition is not satisfied, the first monitoring configuration information is not activated (or called as the first monitoring configuration information is not validated);

wherein the preset condition comprises at least one of the following:

the first condition is as follows: the second PDCCH is not monitored.

And a second condition: PDSCH is not detected.

Wherein, the specific contents of the conditions one, two and three are consistent with the above description.

It should be added that, before the step 22, the method for monitoring the downlink information may further include: and monitoring the second PDCCH according to the second monitoring configuration information. It should be noted that the step of monitoring the second PDCCH according to the second monitoring configuration information may be performed before step 21, or may be performed after step 21.

Wherein the first listening configuration information is associated with the second listening configuration information. Further, the first listening time domain resource indicated by the first listening configuration information is associated with the second listening time domain resource indicated by the second listening configuration information.

Specifically, the first monitoring configuration information is different from the second monitoring configuration information, for example: if at least one of the listening time domain resources, the listening period, the listening offset value, the listening duration, the DCI format, the RNTI, the aggregation level, the search space, and the control resource set is different, it can be considered that the first listening configuration information is different from the second listening configuration information.

It should be noted that, in the embodiment of the present invention, one second listening configuration information may be associated with one or more first listening configuration information, for example, one second listening time domain resource indicated by the second listening configuration information may be associated with one or more first listening time domain resources indicated by the first listening configuration information. In addition, one first listening configuration information may also be associated with one or more second listening configuration information, for example, one first listening time domain resource indicated by the first listening configuration resource may be associated with one or more second listening time domain resources where the PDSCH is located.

Fig. 4a shows a time domain resource diagram of a method for monitoring downlink information, where a monitoring offset value between a PDCCH monitoring location indicated by the first monitoring configuration information and a PDCCH monitoring location indicated by the second monitoring configuration information is T (as indicated by an arrow in fig. 4 a).

Specifically, the second PDCCH is monitored according to the second monitoring configuration information (for example, the second PDCCH is monitored at the PDCCH monitoring position shown in the hatched area in the dashed line frame of fig. 4 a), and if a predetermined condition is met in the process of monitoring the second PDCCH (for example, any one of the first condition, the second condition and the third condition is met), the first PDCCH is monitored according to the first monitoring configuration information (for example, the first PDCCH is monitored at the PDCCH monitoring position shown in the solid white area in the dashed line frame of fig. 4 a), so that power consumption of the terminal caused by blind detection of the PDCCH is reduced, and the effect of saving power of the terminal is achieved.

Further, when the first listening configuration information includes at least two first listening time domain resources, the step 22 specifically includes:

and monitoring the first PDCCH on one of the at least two first monitoring time domain resources.

Fig. 4b shows a schematic time domain resource diagram of another method for monitoring downlink information. Wherein the first listening configuration information includes at least two first listening time domain resources (as shown by solid white areas in fig. 4 b).

Specifically, the second PDCCH is monitored according to the second monitoring configuration information (for example, the second PDCCH is monitored at the PDCCH monitoring position shown in the shaded area in the dashed line frame of fig. 4 b), and if a predetermined condition is met in the process of monitoring the second PDCCH (for example, any one of the first condition, the second condition and the third condition is met), the first PDCCH is monitored according to the first monitoring configuration information (for example, the first PDCCH is monitored at the PDCCH monitoring position shown in a solid white area in the dashed line frame of fig. 4 b), so that the extra power consumption of the terminal caused by blind detection of the PDCCH is reduced, and the power saving effect of the terminal is achieved.

It should be noted that, when the first monitoring configuration information includes two first monitoring time domain resources (solid white regions) shown by a dashed line frame in fig. 4b, the first PDCCH may be monitored on the first monitoring timing resource from the left in the dashed line frame in fig. 4b, or the first PDCCH may be monitored on the second first monitoring timing resource from the left in the dashed line frame in fig. 4 b. Of course, when the first monitoring configuration information includes more than two first monitoring time domain resources, and the first PDCCH is monitored on one of the more than two first monitoring time domain resources, the order of the one of the first monitoring time domain resources on the more than two first monitoring time domain resources is also not limited.

As a case, after the step of monitoring the first PDCCH on one of the at least two first monitoring time domain resources, the following steps may be further performed:

and if the first PDCCH is monitored or the PDSCH is detected, not monitoring the next first monitoring time domain resource in the at least two first monitoring time domain resources.

Specifically, when a preset condition is met, a first PDCCH is monitored on one of at least two first monitoring time domain resources, for example: the first PDCCH is monitored on the first monitoring time domain resource on the left in the dashed line frame of fig. 4, or the PDSCH is detected, the second monitoring time domain resource on the left in the dashed line frame of fig. 4 is not monitored, so that the terminal is prevented from consuming extra power, and the effect of saving power of the terminal is achieved.

As another case, after the step of monitoring the first PDCCH on one of the at least two first monitoring time domain resources, the following steps may be further performed:

and if the first PDCCH is not monitored or the PDSCH is not detected, monitoring the PDCCH on the next first monitoring time domain resource in the at least two first monitoring time domain resources.

Specifically, when a preset condition is met, a first PDCCH is monitored on one of at least two first monitoring time domain resources, for example: monitoring the first PDCCH on the first left first monitoring time domain resource in the dashed line frame of fig. 4, and if the first PDCCH is not monitored or the PDSCH is not detected, monitoring the first PDCCH on the second left first monitoring time domain resource in the dashed line frame of fig. 4.

Further, when the first monitoring configuration information includes at least two sets of monitoring configuration parameters, the step 22 specifically includes:

monitoring the first PDCCH according to one of the at least two sets of monitoring configuration parameters;

and if the first PDCCH is not monitored or the PDSCH is not detected, monitoring the first PDCCH according to other monitoring configuration parameters in the at least two sets of monitoring configuration parameters.

Further, if the first PDCCH is monitored or the PDSCH is detected, other monitoring configuration parameters of the at least two sets of monitoring configuration parameters are not monitored, so as to avoid extra power consumption of the terminal, thereby achieving the effect of saving power of the terminal.

It should be explained that the other monitoring configuration parameters in the at least two sets of monitoring configuration parameters refer to configuration parameters other than the monitored configuration parameters in the at least two sets of monitoring configuration parameters.

Specifically, the configuration parameter may be at least one of the following parameter items: listening time domain resources, listening period, listening offset value, listening duration, DCI format, RNTI, aggregation level, search space, and control resource set. For example: the monitoring period of the first set of monitoring configuration parameters is 20ms, and the monitoring offset value is 10 ms; the second set of listening configuration parameters has a listening period of 20ms and a listening offset value of 15 ms.

It should be added that, before the step 22, the method for monitoring the downlink information further includes:

and determining effective information of the first monitoring configuration information, wherein the effective information is used for indicating that the monitoring configuration information is effective immediately or not.

It should be noted that there is no strict timing relationship between the step of determining the validation information of the first monitoring configuration information and the step 21, that is, the step of determining the validation information of the first monitoring configuration information may be performed before the step 21, or may be performed after the step 21.

The validation information may be indicated by RRC signaling or Medium Access Control (MAC) signaling.

Specifically, the RRC signaling or the MAC signaling includes an information bit associated with the validation information, so as to determine the validation information of the first listening configuration information by displaying the indication.

The validation information may also be indicated by physical layer signaling.

Specifically, the validation information is associated with at least one of the following parameters in the physical layer signaling: a Radio Network Temporary Identifier (RNTI) of physical layer signaling; information bits of physical layer signaling; a search space for physical layer signaling; a search space type of the physical layer signaling; and, a set of control resources for physical layer signaling.

Wherein the validation information is associated with at least one of the following parameters in the physical layer signaling: a Radio Network Temporary Identifier (RNTI) of physical layer signaling; a search space for physical layer signaling; a search space type of the physical layer signaling; and a control resource set of physical layer signaling, which can determine the effective information of the first monitoring configuration information in an implicit indication mode; the validation information is associated with information bits in the physical layer signaling, and the validation information of the first listening configuration information may be determined by displaying an indication.

The following describes the monitoring method of the downlink information in combination with a specific application scenario:

taking a Voice over Internet Protocol (VoIP) as an example, receiving first monitoring configuration information, where the first monitoring configuration information is related to monitoring a first PDCCH; for example: the first monitoring configuration information includes a monitoring period (20ms), a monitoring offset value (10ms) and a monitoring duration (2 symbols), and the first monitoring configuration information related to monitoring the first PDCCH is a possible retransmission for receiving a new downlink packet of the VoIP service.

When a preset condition (any one of the first condition, the second condition and the third condition in the above embodiment) is satisfied, the first PDCCH is monitored according to the first monitoring configuration information. Wherein, the PDSCH scheduled by the second PDCCH in the preset condition is second monitoring configuration information, such as: the method comprises a PDCCH scheduled PDSCH corresponding to a monitoring period (20ms), a monitoring offset value (10ms) and a monitoring duration (2 symbols), or a PDSCH indicated by semi-persistent scheduling. For example: the second monitoring configuration information is to receive a new downlink packet of the VoIP service.

Specifically, when the first monitoring configuration information includes at least two first monitoring time domain resources, the first PDCCH may be monitored on one of the at least two first monitoring time domain resources.

Further, if the first PDCCH is monitored or the PDSCH scheduled by the first PDCCH is detected, the next first monitoring time domain resource of the at least two first monitoring time domain resources is not monitored; and if the first PDCCH is not monitored or the PDSCH scheduled by the first PDCCH is not detected, monitoring the first PDCCH on the next first monitoring time domain resource in the at least two first monitoring time domain resources.

In addition, when the first monitoring configuration information includes at least two sets of monitoring configuration parameters, the first PDCCH may be monitored according to one of the at least two sets of monitoring configuration parameters; and if the first PDCCH is not monitored or the PDSCH scheduled by the first PDCCH is not detected, monitoring the first PDCCH according to other monitoring configuration parameters in the at least two sets of monitoring configuration parameters.

In the method for monitoring downlink information in this embodiment, the terminal monitors the first PDCCH according to the first monitoring configuration information by receiving the first monitoring configuration information related to the first PDCCH when a preset condition is satisfied, so as to reduce extra power consumption of the terminal caused by blind detection of the PDCCH, thereby achieving an effect of saving power of the terminal.
