Configuration method, device and readable storage medium

Technical Field

The present application relates to the field of communications, and more particularly, to a configuration method, apparatus, and readable storage medium.

Background

For example, the network device may send configuration information to the terminal device, and the terminal device may send uplink data to the network device based on the configuration information; as another example, the network device may send downstream data to the terminal device. Thus, the network device 101 and the terminal devices 102 to 107 in fig. 1 constitute one communication system.

As shown in fig. 1, communication may be directly performed between the terminal devices 105 and 106, and between the terminal devices 105 and 107 using D2D technology. Terminal device 106 and terminal device 107 may communicate with terminal device 105 separately or simultaneously.

For example, may communicate directly with network device 101, as terminal devices 105 and 106 in fig. 1 may communicate directly with network device 101; or indirectly with the network device 101, such as the terminal device 107 in fig. 1 via the terminal device 105 with the network device 101.

It should be appreciated that fig. 1 illustrates schematically one network device and a plurality of terminal devices, as well as communication links between the communication devices. Alternatively, the communication system 100 may include a plurality of network devices, and the coverage area of each network device may include other numbers of terminal devices, such as more or fewer terminal devices. The present application is not limited in this regard.

Optionally, the wireless communication system 100 may further include a network controller, a mobility management entity, and other network entities, which embodiments of the present application are not limited thereto.

In order to facilitate understanding of the embodiments of the present application, the following description is first made of the terms involved in the present application.

1. Control resource set (control resource set, CORESET)

CORESET can be understood as a set of time-frequency resources. CORESET may be configured as 1 or several consecutive orthogonal frequency division multiplexing (orthogonal frequency-division multiplexing, OFDM) symbols in the time domain and may be a set of consecutive or non-consecutive frequency domain resources in the frequency domain. One CORESET may correspond to at least one search space. The configuration information for configuring CORESET may include at least one of: an Identification (ID) ID index of CORESET, a demodulation reference signal (demodulation reference signal, DMRS) scrambling sequence initialization value, a duration of CORESET, a CORESET frequency domain resource bitmap, a mapping type (e.g., non-interleaving and interleaving mappings) of control channel elements (control channel element, CCE) to resource element groups (resource element group, REG), a REG bundle size, a cyclic shift value of a REG bundle interleaver, a quasi co-location (QCL) relation with antenna ports, or an indication of whether a transmission configuration indication (transmission configuration indicator, TCI) field is present in the DCI.

2. Search space

The total number of alternative physical downlink control channels (physical downlink control channel, PDCCH) in each search space may be determined by the aggregation level of the search space and the number of alternative PDCCHs in each aggregation level. Each search space is typically composed of alternative PDCCHs corresponding to a given aggregation level, and may also be understood as a set of alternative PDCCHs for blind detection of dci_formats (downlink control information format, dci_formats) of a certain format. The sum of the search spaces corresponding to the plurality of aggregation levels is referred to as a search space set.

The configuration information for configuring the search space may include at least one of the following information: a search space identification, a control resource set (control resource set, CORESET) identification associated with the search space, a period for which the terminal device listens to the search space and a slot offset from the beginning of the listening period to the actual detection search space, a number of slots in which the detection location begins to continuously detect the search space, a time domain starting symbol position of CORESET associated with the search space within each slot, aggregation information included in the search space, and a number of candidate PDCCHs per aggregation, a type of the search space, and a format of the scheduled DCI.

Wherein the types of search spaces include a common search space (common search space, CSS) for detecting common control information and a user-specific search space (UE specific search space, USS) for detecting user-specific control information. The DCI formats for scheduling physical uplink shared channel (physical uplink shared channel, PUSCH) and physical downlink shared channel (physical downlink shared channel, PDSCH) include DCI0-0, DCI0-1, DCI1-0, DCI1-1, wherein DCI0-0 and DCI1-0 are DCI formats for scheduling PUSCH and PDSCH in one cell of a fallback (fallback) type, respectively, and DCI0-1 and DCI1-1 are DCI formats for scheduling PUSCH and PDSCH in one cell of a non-fallback (non-fallback) type, respectively

3. Radio resource control reconfiguration (radio resource control reconfiguration, RRC reconfiguration)

The network device and the terminal device may complete the reconfiguration of parameters, such as establishment, modification and release of Resource Blocks (RBs), handover of partial Bandwidth (BWP), establishment and modification of physical layer locations, or establishment and modification of measurement configurations, etc., through an RRC reconfiguration procedure. The network device may send an RRC reconfiguration message (RRC Reconfiguration) to the terminal device, the RRC reconfiguration message being used to reconfigure configuration parameters of the terminal device, and when the terminal device completes updating the configuration parameters, the terminal device may send an RRC reconfiguration complete message (RRC Reconfiguration Complete) to the network device, notifying that the RRC reconfiguration procedure has been completed. It should be noted that, since the RRC reconfiguration message is generally carried on the PDSCH, the terminal device may successfully receive the RRC reconfiguration message by successfully parsing the PDSCH based on the DCI information.

However, during a first period of time before the network device sends the RRC reconfiguration message and the network device receives the RRC reconfiguration complete message, the network device cannot determine when the terminal device completes the reconfiguration of the parameters, and for ease of understanding the embodiments of the present application, the first period of time is described below with reference to fig. 2.

Fig. 2 shows an explanatory diagram of the first period. Referring to fig. 2, the network device sends an RRC reconfiguration message to the terminal device at time T1, and after a transmission delay, the terminal device receives the RRC reconfiguration message at time T2. The terminal equipment completes the reconfiguration of the parameters at the moment T3, and sends an RRC reconfiguration completion message to the network equipment at the moment T4, and after a period of transmission delay, the network equipment receives the RRC reconfiguration completion message at the moment T5. It can be seen that between time T1 and time T5, the network device does not know when the terminal device can complete the update, and therefore, at time TIn a period of time, the network device may use CSS DCI 0-0/1-0 associated with CORESET0 to implement scheduling of PDSCH and PUSCH, and since PDCCH resources in CORESET0 are located in a fixed resource range, and fixed search information is associated, the carried DCI information has a fixed length and a field format, so that the terminal device can obtain the common PDCCH and parse the carried DCI. In addition, since the common search space DCI 1-0 associated with CORESET0 schedules PDSCH with RB resources within a fixed resource range, the time domain resource configuration parameters (PDSCH time domain resource allocation) of PDSCH use a time domain resource configuration list (PDSCH time domain resource allocation list) provided by the fixed PDSCH configuration parameters (PDSCH configcommon), and fixed scrambling Thus, the terminal device can acquire the PDSCH through which the RRC reconfiguration message is acquired when the PDSCH is acquired based on the DCI information obtained by the parsing.

However, the common PDCCH resources are limited, and a large number of common PDCCH resources are required to be used in the scenarios of establishing connection between the network device and the terminal device, and as the number of users increases continuously, the limited common PDCCH resources may not meet the requirements of a large number of users, and user experience is affected. Therefore, the embodiment of the application provides a configuration method and a configuration device, which can reduce the loss of common PDCCH resources in the RRC reconfiguration process. The configuration method will be described first.

Fig. 3 shows a schematic process diagram of a configuration method provided in an embodiment of the present application.

S310, the network device sends a reconfiguration message to the terminal device, and correspondingly, the terminal device receives the reconfiguration message from the network device.

The reconfiguration message is used for updating configuration information, the reconfiguration message is based on first DCI scheduling, the first DCI is carried on a first PDCCH, the first PDCCH is associated with first configuration information, and the first configuration information is the configuration information before updating.

The reconfiguration message may be an RRC reconfiguration message (RRC reconfiguration), which may include configuration information to be updated, and exemplarily, a name of configuration parameters to be updated, and an updated value, or an index of configuration information to be updated, which may be transmitted to the terminal device by the network device triggering the RRC reconfiguration procedure based on the requirements of the BWP handover or the like.

It will be appreciated that the network device may update different configuration information based on different purpose reconfiguration procedures, which is not particularly limited in this application.

The terminal device may receive the PDSCH to obtain the reconfiguration message, or the reconfiguration message is carried on the PDSCH, or the reconfiguration message is mapped on the PDSCH. Therefore, the terminal device can acquire the first DCI for scheduling the PDSCH, acquire the resource position of the PDSCH by analyzing the first DCI, further receive the PDSCH at the resource position, and further acquire the reconfiguration message.

In one possible implementation, the updating of the configuration information includes updating of at least one of: information for configuring a search space, information for configuring a set of control resources CORESET, information for configuring a fractional bandwidth BWP, information associated with the first DCI length, information associated with a second DCI length. The information associated with the first DCI length may be any information that affects the length of the first DCI, and the information associated with the second DCI length may be any information that affects the length of the second DCI.

The first DCI information is carried on the first PDCCH, and the terminal equipment can acquire the first DCI information by receiving the first PDCCH. Therefore, if the terminal device cannot successfully acquire the PDCCH, the terminal device cannot successfully acquire the first DCI information in the first PDCCH, and further, the terminal device cannot successfully acquire the PDSCH scheduled by the first DCI information and the reconfiguration message in the PDSCH. Since the acquisition of the first PDCCH is associated with the information for configuring BWP, the information for configuring CORESET, and the information for configuring search space, i.e., the terminal device may determine the resource location of the PDCCH based on the configuration information, if one or more of the configuration information is the configuration information to be updated, the resource location of the first PDCCH is associated with the first configuration information before updating, which may enable the terminal device to successfully acquire the first PDCCH.

Illustratively, the reconfiguration message instructs the terminal device to switch from the first BWP to the second BWP, and the updating of the configuration information includes an updating of the configuration information of the BWP, an updating of the configuration information of CORESET, and an updating of the configuration information of the search space. The resource location of the first PDCCH is associated with the pre-update configuration information, i.e. the terminal device may receive the first PDCCH according to the pre-update first configuration information, so that the reliability of the network device sending the reconfiguration message to the terminal device may be improved. In addition, the first PDCCH in the embodiment of the present application is scheduled by using the first configuration information before update that is acquired by the terminal device, instead of scheduling by using the common PDCCH with a fixed PDCCH resource location, so that the overhead of the common PDCCH can be reduced.

Optionally, the reconfiguration message is carried on a first PDSCH, the first PDSCH being associated with the first configuration information.

The updating of the configuration information further includes, for example, updating of scheduling information for scheduling the first PDSCH, the resources of the first PDSCH being associated with pre-update scheduling information, the updating of the scheduling information including updating of at least one of: frequency domain resource allocation (frequency domain resource assignment), time domain resource allocation (time domain resource assignment), modulation and coding strategy Table (modulation and coding scheme-Table, mcs-Table), scrambling code identification (scrambling identity) or antenna port (s)). Therefore, the terminal equipment can acquire the resource position of the PDSCH from the DCI information based on the scheduling information before updating, and successfully acquire the PDSCH at the resource position, so that the reliability of acquiring the reconfiguration message sent by the network equipment is improved.

In one possible implementation, the format of the first DCI may be DCI 1-1. Alternatively, the format of the first DCI is another DCI capable of scheduling PDSCH or a DCI capable of scheduling PDSCH defined in the future, which is not particularly limited in this application.

In one possible implementation, the network device uses the first configuration information to schedule data information in a downlink direction in a time period between sending the reconfiguration message to the terminal device and receiving the reconfiguration complete message from the terminal device.

For example, the network device transmits at least one DCI in DCI 1-1 format in a period between transmitting a reconfiguration message and receiving a reconfiguration complete message, because it cannot be perceived when the terminal device has completed updating the configuration information, and the at least one DCI and the PDCCH carrying the DCI are associated with the pre-update configuration information, i.e., the first configuration information, in the period. If the network device retransmits the reconfiguration message for a plurality of times in the time period, the reconfiguration messages for a plurality of times of retransmission can be all scheduled based on the configuration information before updating, so that the reliability of the network device for sending the reconfiguration message to the terminal device is further improved.

S320, the terminal equipment responds to the reconfiguration message and sends a reconfiguration complete message to the network equipment.

The reconfiguration complete message is based on a second DCI schedule, the second DCI being carried on a second PDCCH, a resource location of the second PDCCH being associated with second configuration information, the second configuration information being updated configuration information.

The reconfiguration complete message may be an RRC reconfiguration complete message (RRC reconfiguration complete) in response to the RRC reconfiguration message.

In one possible approach, the reconfiguration complete message is carried on a first PUSCH associated with the second configuration information.

It should be noted that, the terminal device may map the reconfiguration complete message in the first PUSCH and send the reconfiguration complete message to the network device, or the reconfiguration message may be carried on the first PUSCH. Therefore, the terminal device can acquire the second DCI for scheduling the first PUSCH, acquire the resource position of the first PUSCH by analyzing the second DCI, and then send the first PUSCH at the resource position, and then successfully send the reconfiguration message.

Accordingly, the second DCI information is carried on the second PDCCH, and the terminal device may obtain the second DCI information by receiving the second PDCCH. Therefore, if the terminal device cannot successfully acquire the second PDCCH, the terminal device cannot successfully acquire the second DCI information in the second PDCCH, and further, the terminal device cannot successfully acquire the resource location of the PUSCH scheduled by the second DCI information, and cannot successfully transmit the first PUSCH carrying the reconfiguration completion message. Since the acquisition of the second PDCCH is associated with the information for configuring BWP, the information for configuring CORESET, and the information for configuring search space, i.e., the terminal device may determine the resource location of the PDCCH based on the above configuration information, if one or more of the above configuration information is configuration information to be updated, since the terminal device has completed updating the configuration information, the resource location of the second PDCCH is associated with the updated second configuration information, which may enable the terminal device to successfully acquire the second PDCCH.

In addition, when the updating of the configuration information further includes updating of the scheduling information, the resource position of the first PUSCH is associated with the updated scheduling information, and the terminal device may acquire the resource position of the first PUSCH from the DCI information based on the updated scheduling information, and successfully send the first PUSCH at the resource position, thereby improving reliability of sending the reconfiguration completion message to the network device.

In one possible implementation, the format of the first DCI may be DCI 0-1. Alternatively, the format of the first DCI is another format capable of scheduling PUSCH or a DCI capable of scheduling PUSCH defined in the future, which is not particularly limited in this application.

In one possible implementation, the network device uses the second configuration information to schedule data information in an uplink direction in a period between sending the reconfiguration message to the terminal device and receiving the reconfiguration complete message from the terminal device.

For example, the network device may send at least one DCI in DCI 0-1 format in a period between sending and receiving the reconfiguration complete message, because it cannot be perceived when the terminal device has completed updating the configuration information, and the at least one DCI and the PDCCH carrying the DCI are associated with the updated configuration information, i.e. the second configuration information. If the terminal equipment completes the updating of the configuration information, the resource for sending the reconfiguration message can be acquired for multiple times based on the second configuration information, namely the terminal equipment can retransmit the reconfiguration completion message for multiple times, so that the reliability of sending the reconfiguration completion message to the network equipment by the terminal equipment is further improved.

In order to facilitate understanding of the present technical solution, an implementation manner of the foregoing embodiment is described below with reference to fig. 4. Fig. 4 shows an explanatory diagram of a configuration method. The time period between the network device sending the reconfiguration message and receiving the reconfiguration complete message is a first time period, in the first time period, the PDSCH in the downlink direction is scheduled by the PDCCH (not shown) associated with the first configuration information, the PDSCH in the downlink direction uses the first configuration information before updating, the PUSCH in the uplink direction is scheduled by the PDCCH (not shown) associated with the second configuration information, and the PUSCH in the uplink direction uses the second configuration information after updating, so that before the configuration information is updated, the terminal device can acquire the reconfiguration message in the PDSCH based on the first configuration information, and after the configuration information is updated, the PUSCH carrying the reconfiguration complete message is sent based on the second configuration information.

Based on the technical scheme, the network equipment can schedule the reconfiguration message based on the configuration information before updating, so that the terminal equipment can successfully receive the reconfiguration message from the network equipment, and the reliability of the transmission of the reconfiguration message is improved. In addition, the PDCCH used for scheduling the reconfiguration message in the technical scheme is not a limited public PDCCH, so that the consumption of public PDCCH resources in the reconfiguration process can be reduced.

The above method adopts the configuration information before updating to perform downlink scheduling and the configuration information after updating to perform uplink scheduling, so that the consumption of public PDCCH resources in the reconfiguration process can be reduced. The embodiment of the application also provides a configuration method, which can reduce the consumption of the common PDCCH resources by configuring the control resource set of non-CORESET 0 to be associated with the DCI, and the method is described below with reference to fig. 5.

Fig. 5 shows a schematic process diagram of another configuration method provided in an embodiment of the present application.

Optionally, S510, the network device sends first information to the terminal device, and correspondingly, the terminal device receives the first information from the network device.

The first information is used to configure the first PDCCH to be associated with a first set of control resources CORESET and a first search space. Wherein the first CORESET and the first search space can be used for a common search space, the first CORESET being non-CORESET 0. That is, the first CORESET common search space is not the common search space associated with CORESET0. The first DCI is used to schedule a reconfiguration message, which is used for updating configuration information. Thereby enabling a reduction in the consumption of limited common search space resources of CORESET0.

In one possible implementation, the first information may include information for configuring the first CORESET, and information for configuring the first search space, where the first information includes content that may be referred to above in connection with the CORESET configuration information and the search space information, which is not particularly limited herein. Furthermore, the terminal device may obtain the PDCCH carrying the first DCI according to the first CORESET configured by the configuration information.

In one possible implementation, the format of the first DCI is DCI1-0.

Based on the first information, the terminal equipment can acquire the PDCCH bearing the first DCI according to the first CORESET and the first search space, and further can acquire the PDSCH bearing the reconfiguration message based on the first DCI, so that the reliability of the terminal equipment for receiving the reconfiguration message can be improved.

In addition, the first information may indicate that the terminal device obtains the first DCI based on the configuration of the first CORESET in a case where COREST0 is not included on the user BWP or where COREST0 is congested on the user, for example, a busy rate on COREST0 is greater than or equal to a specific threshold.

Illustratively, if COREST0 is not configured on the user BWP of the terminal device, the terminal device obtains the first DCI based on the first CORESET and the configuration of the first search space; if COREST0 is configured on user BWP of the terminal device, but a busy rate on COREST0 is greater than or equal to a certain threshold, the terminal device also obtains a first DCI based on the configuration of the first CORESET and the first search space; if COREST0 is configured on the user BWP of the terminal device and the busy rate on COREST0 is less than a specific threshold, the terminal device may acquire the first DCI based on the configuration of COREST0, so that the reliability of acquiring the reconfiguration message by the terminal device can be further improved.

S520, the network device sends the reconfiguration message to the terminal device, and correspondingly, the terminal device receives the reconfiguration message from the network device.

The reconfiguration message may be an RRC reconfiguration message, and the description of the reconfiguration message may refer to the description of the reconfiguration message in step S310 in the method 300, which is not described herein.

It may be appreciated that the configuration information of the first core and the first search space associated with the first DCI may be configured through the first information in step S510, or may be configured in a pre-configured manner, which is not limited in this application.

It is noted that when the reconfiguration message also includes a configuration update of CORESET and search space, the first DCI for scheduling the reconfiguration message is still associated with the first CORESET and the first search space. When the network device completes the reconfiguration process, that is, after the network device receives the reconfiguration completion message sent by the terminal, the network device performs scheduling based on the configuration information updated by the reconfiguration message.

And S530, the terminal equipment responds to the reconfiguration message and sends the reconfiguration complete message to the network equipment, and correspondingly, the network equipment receives the reconfiguration complete message from the terminal equipment.

The reconfiguration complete message may be an RRC reconfiguration complete message (RRC reconfiguration complete) in response to the RRC reconfiguration message. The description of the reconfiguration message may refer to the description of step S320 in the method 300, which is not repeated herein.

In one possible implementation, a second DCI is used to schedule a reconfiguration complete message, the second DCI being associated with the first core and a first search space.

In one possible implementation, the format of the first DCI is DCI0-0.

Illustratively, in the period between sending the reconfiguration message and receiving the reconfiguration complete message, the network device associates the DCI for scheduling the PDSCH and the PUSCH with the first CORESET and the first search space configured by the configuration information, so that the network device reconfiguration process may not depend on the common search space resource of CORESET0, and overhead of the common search space resource is saved.

It is to be understood that the description of the device embodiments corresponds to the description of the method embodiments, and that parts not described in detail can therefore be seen in the preceding method embodiments.
