Description

Physical downlink control channel monitoring parameter configuration method, terminal and network side equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, a terminal, and a network side device for configuring a physical downlink control channel monitoring parameter.

Background

A Physical Downlink Control Channel (PDCCH) is used for scheduling a data Channel. A User Equipment (UE) cannot initially know the number and position of Control Channel elements (Control Channel elements) occupied by a PDCCH and a format of Downlink Control Information (DCI) transmitted. Blind detection of the PDCCH by the UE is required.

Specifically, the base station configures a monitoring period for blind detection for the PDCCH. The base station notifies the UE of the monitoring period of the PDCCH. And the UE monitors the PDCCH according to the monitoring period. However, the monitoring period of the PDCCH configured by the base station may not match the arrival period of the service packet, thereby causing ineffective PDCCH monitoring. For example, the arrival period of the service packet is 20 ms, and the monitoring period configured by the base station for the PDCCH is 2 ms. There is a case where the UE performs blind detection on the PDCCH but does not detect the PDCCH. The UE needs to consume a certain amount of power to monitor the PDCCH each time, thereby increasing power consumption of the UE in monitoring the PDCCH.

Detailed Description

Features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention. The present invention is in no way limited to any specific configuration and algorithm set forth below, but rather covers any modification, replacement or improvement of elements, components or algorithms without departing from the spirit of the invention. In the drawings and the following description, well-known structures and techniques are not shown in order to avoid unnecessarily obscuring the present invention.

The embodiment of the invention provides a method for configuring monitoring parameters of a physical downlink control channel, a terminal and network side equipment, which can be applied to a scene that the terminal communicates with the network side equipment and monitors the physical downlink control channel. The terminal and the network side equipment can communicate with each other, and specifically comprises that the terminal sends service data to the network side equipment, and the network side equipment sends the service data to the terminal. The action of sending the service data to the network side equipment by the terminal is uplink communication. The action of the network side equipment sending the service data to the terminal is downlink communication. In some examples, the terminal may be a mobile phone, a tablet computer, a smart watch, a smart home appliance, and the like, without limitation. Fig. 1 is a schematic view of a scenario according to an embodiment of the present invention. As shown in fig. 1, there are three terminals, terminal B1, terminal B2 and terminal B3, in the signal coverage of the network-side device a. The network side device a and each terminal can perform uplink communication and downlink communication. The network side device a provided in the embodiment of the present invention may be a base station, which may be a commonly used base station, an evolved node base station (eNB), a network side device in a 5G system (for example, a next generation base station (gNB), a Transmission and Reception Point (TRP), a cell, or the like), or a network side device in a subsequent evolved communication system. The terminology, however, is not intended to limit the scope of the present invention.

In order to effectively manage a communication network including a network side device and a terminal, a resource occupied by a Physical Downlink Control Channel (PDCCH) needs to be known. The PDCCH can carry uplink and downlink control information of the network side device and the terminal. For example, the control information carried by the PDCCH may include common control information and dedicated control information. The PDCCH may also carry scheduling information of a Physical Uplink Shared Channel (PUSCH) and scheduling information of a Physical Downlink Shared Channel (PDSCH). The scheduling Information carried by the PDCCH channel is referred to as Downlink Control Information (DCI). The time-frequency resource set occupied by the PDCCH is a control resource set (i.e., CORESET). The terminal searches a specific Radio Network Temporary Identity (RNTI) in a Search Space (Search Space) of the PDCCH, and if the RNTI corresponding to the terminal is searched, the terminal detects the PDCCH. The terminal may periodically monitor the PDCCH according to monitoring parameters such as a monitoring period and an offset. For example, the PDCCH is monitored every 5 milliseconds.

In order to enable the configured monitoring parameters of the PDCCH to be relatively matched with the transmission cycle of the service packet in the actual situation and avoid unnecessary PDCCH monitoring, the embodiment of the invention provides a method for configuring the monitoring parameters of the PDCCH.

Fig. 2 is a flowchart of a PDCCH monitoring parameter configuration method according to an embodiment of the present invention. The execution main body of the PDCCH monitoring parameter configuration method is a terminal. As shown in fig. 2, the PDCCH monitoring parameter configuring method includes step S101.

In step S101, a configuration request of the monitoring parameters of the PDCCH is sent to the network side device.

The configuration request is used for requesting the configuration of the monitoring parameters from the network side equipment. The configuration request may include the monitoring parameters of the PDCCH, or factors affecting the monitoring parameters of the PDCCH. And the monitoring parameters of the PDCCH are used for configuring the monitoring of the terminal on the PDCCH. The monitoring parameters of the PDCCH may be obtained according to factors affecting the monitoring parameters of the PDCCH.

In an actual communication network, a terminal sends uplink service to network side equipment through uplink communication. And the network side equipment sends downlink service to the terminal through downlink communication. The terminal can obtain the monitoring parameters of the PDCCH or the factors influencing the monitoring parameters of the PDCCH according to the downlink service in downlink communication or the uplink service in uplink communication.

In the embodiment of the invention, the terminal sends a configuration request comprising monitoring parameters of the PDCCH or factors influencing the monitoring parameters of the PDCCH to the network side equipment. That is, the terminal may estimate in advance the monitoring parameters of the PDCCH or the factors affecting the monitoring parameters of the PDCCH according to the information related to the downlink service or the uplink service. Therefore, the monitoring parameters with high matching degree with the arrival period of the service packet are requested to be configured through the configuration request, the condition that the terminal monitors the PDCCH but does not detect the PDCCH is further reduced, and the electric quantity consumption of the terminal monitoring the PDCCH is reduced. Meanwhile, the memory occupied by the terminal for monitoring the PDCCH can be reduced.

In some examples, the listening parameters include a listening period. Alternatively, the listening parameters include a listening period and an offset (i.e., offset). Wherein, the monitoring period is a period for the terminal to monitor the PDCCH. The offset is used to indicate on which slot (i.e., slot) or slots of the monitoring period the PDCCH is monitored. For example, the monitoring period of the PDCCH requested by the terminal to the network side device is 10 slots, and the monitoring offset is the 4 th slot and the 5 th slot in the monitoring period of each 10 slots. For another example, the monitoring period of the PDCCH requested by the terminal to the network side device is 20 slots, and the monitoring offset is the first slot in the monitoring period of each 20 slots.

It should be noted that, the network side device may also configure the monitoring period and the offset of the PDCCH for the terminal according to the foregoing manner.

The larger the PDCCH monitoring period is, the less the monitoring times are within the same time length. Similarly, the smaller the monitoring period is, the more the monitoring times are within the same duration. The closer the time slot for monitoring the PDCCH is to a Synchronization Signal Block (SSB), the faster the terminal can detect the PDCCH on the corresponding time slot after the SSB completes downlink Synchronization, and the less power the terminal consumes. Therefore, the terminal can request the time for monitoring the PDCCH by the offset within a certain time after the downlink synchronization is completed by the SSB. The time when the network side equipment monitors the PDCCH through the terminal configuration is set to be within a certain time after the downlink synchronization is completed through the SSB through the offset.

In some examples, the factors affecting the monitoring parameters of the PDCCH may include one or a combination of uplink traffic packet arrival period, uplink traffic packet size, uplink data transmission rate, uplink traffic delay requirement, remaining power of the terminal, and temperature of the terminal, which are not limited herein.

The uplink service packet arrival period is used to indicate a period, such as an average period, in which the uplink service packet arrives at the terminal buffer. The uplink data transmission rate can be obtained by the quotient of the total amount of the uplink service packets in a period of statistical time and the statistical time. The uplink service delay requirement is used for indicating the requirement of the uplink service packet on the delay in uplink communication.

In other examples, the factors affecting the monitoring parameters of the PDCCH may include one or a combination of a downlink traffic packet arrival period, a downlink traffic packet size, a downlink data transmission rate, a downlink traffic delay requirement, a remaining power of the terminal, and a temperature of the terminal, which are not limited herein.

The downlink service packet arrival period is used to indicate a generation period, such as an average period, of the downlink service packet. The downlink data transmission rate can be obtained by the quotient of the total amount of the downlink service packets in a period of statistical time and the statistical time. The downlink service delay requirement is used for indicating the requirement of the downlink service packet on the delay in downlink communication.

It should be noted that, the monitoring parameters of the PDCCH may be determined according to factors affecting the monitoring parameters of the PDCCH.

For example, the uplink traffic packet arrival period or the downlink traffic packet arrival period may be used as the PDCCH monitoring period. Or, the PDCCH monitoring period is obtained by considering other factors on the basis of the uplink service packet arrival period or the downlink service packet arrival period.

For example, if the size of the uplink service packet or the size of the downlink service packet is too large (for example, the size of the uplink service packet or the size of the downlink service packet exceeds a data threshold), the uplink service packet or the downlink service packet needs to be successfully transmitted through multiple data scheduling, and the PDCCH monitoring period can be reduced to increase the transmission opportunity of the service packet.

For example, if the uplink data transmission rate or the downlink data transmission rate is faster (e.g., the uplink data transmission rate or the downlink data transmission rate exceeds the first rate threshold), the PDCCH monitoring period may be reduced. If the uplink data transmission rate or the downlink data transmission rate is slow (if the uplink data transmission rate or the downlink data transmission rate is lower than the second rate threshold, and the second rate threshold is smaller than the first rate threshold), the PDCCH monitoring period may be increased.

For example, if the uplink traffic delay requirement or the downlink traffic delay requirement is low (for example, the uplink traffic delay requirement or the downlink traffic delay requirement is lower than the first requirement threshold), the PDCCH monitoring period may be increased. If the uplink service delay requirement or the downlink service delay requirement is high (if the uplink service delay requirement or the downlink service delay requirement is higher than the second requirement threshold, and the second requirement threshold is higher than the first requirement threshold), the PDCCH monitoring period can be reduced.

For example, if the remaining power of the terminal is low (e.g., the remaining power of the terminal is lower than the power threshold), the PDCCH monitoring period may be increased to achieve the purpose of saving power.

For example, if the temperature of the terminal is high (e.g., if the temperature of the terminal is higher than the temperature threshold), the PDCCH monitoring period may be increased to decrease the temperature of the terminal.

The monitoring parameters of the PDCCH can also be obtained by combining the above factors affecting the monitoring parameters of the PDCCH. For specific combinations, reference may be made to the above description, which is not repeated herein.

In some examples, step S101 in the foregoing embodiments may be specifically implemented to transmit a configuration request of the monitoring parameters of the PDCCH to the network side device through the PUSCH. For example, when the terminal performs Uplink data scheduling, for example, the terminal may send a configuration request of the monitoring parameters of the PDCCH to the network side device through a PUSCH scheduled by an Uplink grant (i.e., Uplink grant).

In other examples, step S101 in the foregoing embodiment may be specifically implemented to send a configuration request of the monitoring parameters of the PDCCH to the network side device through a Physical Uplink Control Channel (PUCCH).

In still other examples, step S101 in the above embodiments may be specifically implemented to send a configuration request of monitoring parameters of the PDCCH to the network side device through a Physical Random Access Channel (PRACH). for example, the configuration request of monitoring parameters of the PDCCH may be sent to the network side device through a Message _1 or a Message _3 of Random Access.

Since the PDCCH carries various control information, the monitoring parameters matched with the service packets corresponding to different control information may be different. Thus, the configuration request sent by the terminal may include a combination of one or more of:

monitoring parameters of a PDCCH corresponding to one or more Downlink Control Information formats (DCI formats), monitoring parameters of a PDCCH corresponding to one or more RNTIs, monitoring parameters of a PDCCH corresponding to one or more Search Space types, monitoring parameters of a PDCCH corresponding to one or more Search spaces, monitoring parameters of a PDCCH corresponding to one or more Search Space sets (Search Space sets), and monitoring parameters of a PDCCH corresponding to one or more Control resource sets (i.e., CORESET).

That is, different PDCCH monitoring parameters may be configured for different DCI formats. For example, for DCI format 0_1, the requested monitoring parameter of PDCCH is 10 ms or 10 slots; for DCI format 1_1, the requested monitoring parameter of the PDCCH is 20 ms or 20 slots. Different listening parameters may be configured for different search space types. For example, the search space types include a common search space and a dedicated search space. In a further specific subdivision, the common search space may also include common search spaces of different scrambling schemes. The dedicated search space may also include dedicated search spaces of different scrambling patterns. Different PDCCH monitoring parameters can be configured for different kinds of search spaces. Different listening parameters may be configured for different search spaces of the same search space type. The set of search spaces may include multiple search spaces, e.g., search spaces of the same type may make up a set of search spaces. Different listening parameters may be configured for different sets of search spaces. Different listening parameters may be configured for different RNTIs. Different listening parameters may be configured for different sets of control resources.

For example, if a service with a long packet arrival period is in progress in communication between the terminal and the network side device. Before the terminal sends a configuration request of monitoring parameters of the PDCCH to the network side equipment, the network side equipment configures the terminal to monitor the PDCCH in each time slot. There are cases where a large number of terminals perform blind detection on the PDCCH, but do not detect the PDCCH. The terminal can send a configuration request of monitoring parameters of the PDCCH to the network side equipment according to the specific situation of the terminal on the uplink service between the terminal and the network side equipment. And the terminal determines that the DCI format is 0_1 according to the specific situation of the uplink service. The terminal may report a configuration request with a PDCCH monitoring period of 10 ms or 10 timeslots corresponding to the DCI format 0_1 to the network side device.

For another example, if a service with a long packet arrival period is in progress in communication between the terminal and the network side device. Before the terminal sends a configuration request of monitoring parameters of the PDCCH to the network side equipment, the network side equipment configures the UE to monitor the PDCCH in each time slot. There are cases where a large number of terminals perform blind detection on the PDCCH, but there are no traffic packets in the PDCCH. The terminal can send a configuration request of monitoring parameters of the PDCCH to the network side equipment according to the specific situation of the terminal on the uplink service between the terminal and the network side equipment. The terminal determines that the DCI format is 0_1 according to the specific situation of the uplink service, and the DCI format 0_1 is configured on the second search space 2. The terminal may report a configuration request with a monitoring period of 10 ms or 10 timeslots for the PDCCH corresponding to the search space 2 to the network side device.

For example, if a service with a long service packet arrival period is in progress in communication between the terminal and the network side device. Before the terminal sends a configuration request of monitoring parameters of the PDCCH to the network side device, the network side device configures the terminal to monitor the PDCCH once every 10 time slots, and monitors the PDCCH at the 2 nd time slot of the 10 time slots (that is, the offset is 2 time slots). The time interval from downlink synchronization to PDCCH monitoring is long, and the terminal needs to wait for a long time. The terminal determines that the 8 th slot is closest to the SSB and determines that the appropriate offset is 8 slots. The terminal may set a configuration request including a listening period of 10 slots and an offset of 8 slots, and send the configuration request to the network side device.

In some examples, the factors affecting the monitoring parameters of the PDCCH may include a traffic class. The service class is used to identify service packages of different configuration requirements. The service level may be set according to a working scenario and a working requirement, and is not limited herein. The service level has a mapping relation with the monitoring parameter. For example, the traffic class and listening parameters may form a mapping table. And recording each service level and the monitoring parameters corresponding to the service level in the mapping table. For example, the traffic class is the first class, and the listening period corresponding to the first class is 5 ms or 5 slots. The service class is the second level, the corresponding monitoring period of the second level is 10 milliseconds or 10 time slots, and the offset is 2. The service class is the third level, and the listening period corresponding to the third level is 20 milliseconds or 20 time slots. The traffic class may also be referred to herein as the monitoring class of the PDCCH or other terminology.

The terminal can realize the configuration of the monitoring parameters of the PDCCH through the information interaction with the network side equipment. Three specific embodiments will be described below to perform a PDCCH monitoring parameter configuration method on the terminal side. It should be noted that the PDCCH monitoring parameter configuring method protected by the present invention includes, but is not limited to, the following three specific embodiments.

Fig. 3 is a flowchart of a PDCCH monitoring parameter configuration method according to a first embodiment of the present invention. Fig. 3 is different from fig. 1 in that the PDCCH monitoring parameter configuration method shown in fig. 3 further includes step S102 and step S103.

In step S102, the monitoring parameters of the reconfigured PDCCH are received from the network side device.

After receiving the configuration request sent by the terminal, the network side device may reconfigure the monitoring parameters of the PDCCH according to the configuration request, and send the reconfigured monitoring parameters of the PDCCH to the terminal. And the terminal receives the monitoring parameters of the reconfigured PDCCH from the network side equipment.

It should be noted that the monitoring parameter of the reconfigured PDCCH received by the terminal from the network side device is related to the configuration request sent by the terminal to the network side device. If the configuration request sent by the terminal to the network-side device includes the monitoring parameter, the monitoring parameter of the reconfigured PDCCH received by the terminal from the network-side device in step S102 may be the same as the monitoring parameter in the configuration request, or may be adjusted based on the monitoring parameter in the configuration request to obtain a new monitoring parameter, which is not limited herein.

In some examples, the terminal receives the monitoring parameters of the reconfigured PDCCH from the network side device through a Radio Resource Control (RRC) message, or a Media Access Control (MAC) message, or a Downlink Control Information (DCI).

In step S103, the PDCCH is monitored according to the monitoring parameters of the reconfigured PDCCH.

For example, if the monitoring parameter includes a monitoring period, the terminal monitors the PDCCH according to the monitoring period of the reconfigured PDCCH. And if the monitoring parameters comprise the monitoring period and the offset, the terminal monitors the PDCCH according to the monitoring period and the offset of the reconfigured PDCCH.

Fig. 4 is a flowchart of a PDCCH monitoring parameter configuration method according to a second embodiment of the present invention. Fig. 4 is different from fig. 1 in that the PDCCH monitoring parameter configuration method shown in fig. 4 further includes step S104 and step S105.

In step S104, confirmation information indicating agreement with the configuration request is received from the network-side device.

Wherein the acknowledgement information does not include the listening parameter. And the confirmation information represents that the network side equipment agrees the terminal to monitor the PDCCH according to the monitoring parameters in the configuration request. Or, the confirmation information represents that the network side equipment agrees that the terminal monitors the PDCCH according to the monitoring parameters obtained according to the factors influencing the monitoring parameters of the PDCCH in the configuration request.

In some examples, the terminal receives the acknowledgement information from the network side device through an RRC message, or a MAC message, or DCI.

In step S105, the PDCCH is monitored according to the monitoring parameters of the PDCCH indicated by the configuration request.

If the configuration request sent by the terminal to the network side device includes the monitoring parameter, the terminal monitors the PDCCH according to the monitoring parameter in the configuration request. If the configuration request sent by the terminal to the network side device before includes the factors affecting the monitoring parameters of the PDCCH, the terminal may determine the monitoring parameters according to the factors affecting the monitoring parameters of the PDCCH in the configuration request, and monitor the PDCCH according to the monitoring parameters.

Fig. 5 is a flowchart of a PDCCH monitoring parameter configuration method according to a third embodiment of the present invention. Fig. 5 is different from fig. 1 in that the PDCCH monitoring parameter configuring method shown in fig. 5 further includes step S106.

In step S106, the PDCCH is monitored according to the monitoring parameter of the PDCCH indicated by the configuration request.

In this embodiment, whether the network side device sends the reconfigured listening parameters or the acknowledgement information is not considered. The terminal can monitor the PDCCH directly according to the monitoring parameters of the PDCCH indicated by the configuration request.

Fig. 6 is a flowchart of a PDCCH monitoring parameter configuration method according to another embodiment of the present invention. The execution main body of the PDCCH monitoring parameter configuration method is network side equipment. As shown in fig. 6, the PDCCH monitoring parameter configuring method includes step S201.

In step S201, a configuration request of monitoring parameters of the PDCCH is received from the terminal.

Wherein the configuration request includes monitoring parameters of the PDCCH, or factors affecting the monitoring parameters of the PDCCH.

In an actual communication network, an uplink service packet is sent to a network side device through an uplink communication terminal, and a downlink service packet is sent to a terminal through a downlink communication network side device. The monitoring parameters of the PDCCH in the configuration request received by the network side device from the terminal, or the factors affecting the monitoring parameters of the PDCCH, are obtained by the terminal according to the downlink service in downlink communication or the uplink service in uplink communication.

In the embodiment of the present invention, a network side device receives, from a terminal, a configuration request including monitoring parameters of a PDCCH or factors affecting the monitoring parameters of the PDCCH. And the monitoring parameters of the PDCCH or factors influencing the monitoring parameters of the PDCCH in the configuration request received by the network side equipment are obtained by estimating in advance by the terminal according to the relevant information of the downlink service or the uplink service. The network side equipment can determine the monitoring parameters with higher matching degree with the arrival period of the service packet through the configuration request, thereby reducing the condition that the terminal monitors the PDCCH but does not detect the PDCCH, and reducing the electric quantity consumption of the terminal monitoring the PDCCH. In addition, the memory occupied by the terminal for monitoring the PDCCH can be reduced.

It should be noted that, for the relevant description of the monitoring parameters of the PDCCH and the factors affecting the monitoring parameters of the PDCCH, please refer to the relevant contents in the above embodiments, which is not described herein again.

In some examples, step S201 in the above embodiments may be specifically implemented to receive a configuration request of the monitoring parameters of the PDCCH from the terminal through the PUSCH. For example, when performing Uplink data scheduling, for example, a PUSCH scheduled by an Uplink grant (i.e., Uplink grant) may receive a configuration request of a monitoring parameter of a PDCCH from a terminal.

In other examples, step S201 in the above embodiments may be implemented by receiving a configuration request of monitoring parameters of a PDCCH from a terminal through a PUCCH.

In still other examples, step S201 in the above embodiments may be implemented by receiving a configuration request of monitoring parameters of a PDCCH from a terminal through a PRACH. For example, the configuration request of the monitoring parameters of the PDCCH may be received from the terminal through Message _1 or Message _3 of random access.

monitoring parameters of a PDCCH corresponding to one or more DCI formats, monitoring parameters of a PDCCH corresponding to one or more RNTIs, monitoring parameters of a PDCCH corresponding to one or more search space types, monitoring parameters of a PDCCH corresponding to one or more search spaces, monitoring parameters of a PDCCH corresponding to one or more search space sets, and monitoring parameters of a PDCCH corresponding to one or more control resource sets.

For the configuration request and the relevant description of configuring the listening parameters according to the configuration request, refer to the relevant contents in the above embodiments, which are not described herein again.

In some examples, the factors affecting the monitoring parameters of the PDCCH may include a traffic class. The service level has a mapping relation with the monitoring parameter. For the description of the service level and the monitoring parameters, refer to the related contents in the above embodiments, which are not described herein again.

The network side equipment can realize the configuration of the monitoring parameters of the PDCCH through the information interaction with the terminal. Two specific embodiments will be used to perform the PDCCH monitoring parameter configuration method on the terminal side. It should be noted that the PDCCH monitoring parameter configuring method protected by the present invention includes, but is not limited to, the following two specific embodiments.

Fig. 7 is a flowchart of a PDCCH monitoring parameter configuration method according to a first embodiment of the present invention. Fig. 7 is different from fig. 6 in that the PDCCH monitoring parameter configuration method shown in fig. 7 further includes step S202 and step S203.

In step S202, the monitoring parameters of the PDCCH are reconfigured according to the configuration request.

If the configuration request includes the monitoring parameters of the PDCCH, the network side device may directly reconfigure the monitoring parameters of the PDCCH. If the configuration request includes the factors affecting the monitoring parameters of the PDCCH, the network side device may determine the monitoring parameters of the PDCCH according to the factors affecting the monitoring parameters of the PDCCH.
