Description

Resource allocation method, network device and computer storage medium
Technical Field
The present application relates to the field of communications technologies, and in particular, to a resource allocation method, a network device, and a computer storage medium.
Background
When the terminal device is in a Discontinuous Reception (DRX) mode, the network device at the base station side needs to instruct the terminal device to measure and report Channel State Information (CSI).
The CSI measurement resource and the reporting resource of the terminal equipment are configured by the network equipment at the base station side. At present, when a network device on a base station side configures CSI measurement resources and reports resources for a terminal device, the same resource configuration scheme is often adopted.
However, in different DRX cycles, the states of the terminal devices are different greatly, and it is difficult to adapt to different terminal states in a wireless communication system by using a single resource allocation scheme, which easily causes too much or too little resource allocation.
Disclosure of Invention
In view of this, embodiments of the present application provide a resource allocation method, a network device, and a computer storage medium, so as to solve the problem that, in the prior art, a single resource allocation scheme is difficult to adapt to different terminal states in a wireless communication system, and resource allocation is easily too much or too little.
A first aspect of an embodiment of the present application provides a resource allocation method, including:
the method comprises the steps that network equipment obtains a first parameter corresponding to a DRX cycle to be configured, and inquires resource configuration information corresponding to the first parameter in a preset resource configuration table;
and the network equipment sends the resource configuration information to terminal equipment to indicate the terminal equipment to measure and report channel state information according to the resource configuration information.
It should be noted that, the DRX cycle to be configured may be set according to a configuration scheme of a user. The DRX cycle to be configured may be a DRX cycle with data transmission, or may be each DRX cycle.
The type of the first parameter may be selected according to the actual situation. The preset resource configuration information table is a resource configuration table preset by a user. The preset resource allocation table records the corresponding relationship between the first parameter and the resource allocation information. The user can determine the resource configuration information corresponding to each first parameter through experimental tests, theoretical calculations and other manners, so as to obtain the corresponding relationship between the first parameters and the resource configuration information, and establish a preset resource configuration table.
In a possible implementation manner of the first aspect, the first parameter is a cycle length of the DRX cycle to be configured;
correspondingly, the network device obtaining a first parameter corresponding to a DRX cycle to be configured, and querying resource configuration information corresponding to the first parameter in a preset resource configuration table includes:
the network equipment acquires the cycle length of a DRX cycle to be configured, and inquires resource configuration information corresponding to the cycle length in a preset resource configuration table.
It should be noted that, the longer the cycle length of the DRX cycle to be configured is, the higher the possibility that data interaction occurs between the network device and the user terminal device in the DRX cycle to be configured is, the more CSI measurement resources and reporting resources should be configured by the network device; the shorter the cycle of the DRX cycle to be configured is, the lower the possibility that data interaction occurs between the network device and the user terminal device in the DRX cycle to be configured is, and the less CSI measurement resources and reporting resources should be configured by the network device.
Therefore, the resource configuration can be performed according to the cycle length of the DRX cycle to be configured by using the cycle length of the DRX cycle to be configured as the first parameter.
In another possible implementation manner of the first aspect, the first parameter is a cycle type of the DRX cycle to be configured;
correspondingly, the network device obtaining a first parameter corresponding to a DRX cycle to be configured, and querying resource configuration information corresponding to the first parameter in a preset resource configuration table includes:
the network equipment acquires the cycle type of the DRX cycle to be configured, and inquires resource configuration information corresponding to the cycle type in a preset resource configuration table.
It should be noted that the cycle types of the DRX cycle to be configured may include a short DRX cycle and a long DRX cycle. When the cycle type of the DRX cycle to be configured is a short DRX cycle, the probability of data interaction between the network equipment and the user terminal equipment in the DRX cycle to be configured is low, and the network equipment should be configured with less CSI measurement resources and reporting resources; when the cycle type of the DRX cycle to be configured is a long DRX cycle, the probability that data interaction occurs between the network device and the user terminal device in the DRX cycle to be configured is high, and the network device should configure more CSI measurement resources and reporting resources.
Therefore, the cycle type of the DRX cycle to be configured may be used as the first parameter, and the resource configuration may be performed according to the cycle type of the DRX cycle to be configured.
In another possible implementation manner of the first aspect, the first parameter is a total sleep time of the terminal device before the DRX cycle to be configured;
correspondingly, the network device obtaining a first parameter corresponding to a DRX cycle to be configured, and querying resource configuration information corresponding to the first parameter in a preset resource configuration table includes:
the network equipment acquires the total sleep time of the terminal equipment before a DRX period to be configured, and determines a sleep time interval of the total sleep time;
and the network equipment inquires resource configuration information corresponding to the dormancy time interval in a preset resource configuration table.
It should be noted that, if the total sleep time of the terminal device before the DRX cycle to be configured is longer, the network device should configure more CSI measurement resources and reporting resources; if the total sleep time of the terminal device before the DRX cycle to be configured is shorter, the network device should configure fewer CSI measurement resources and reporting resources.
Therefore, the total sleep time of the terminal device before the DRX period to be configured can be used as a first parameter, and the resource configuration can be carried out according to the total sleep time of the terminal device before the DRX period to be configured.
In another possible implementation manner of the first aspect, the first parameter is a total number of times of sleep of the terminal device before the DRX cycle to be configured;
correspondingly, the network device obtaining a first parameter corresponding to a DRX cycle to be configured, and querying resource configuration information corresponding to the first parameter in a preset resource configuration table includes:
the network equipment acquires the total dormancy times of the terminal equipment before the DRX period to be configured, and inquires resource configuration information corresponding to the total dormancy times in a preset resource configuration table.
It should be noted that, if the total number of times of dormancy of the terminal device before the DRX cycle to be configured is more, the network device should configure more CSI measurement resources and reporting resources; if the total sleep times of the terminal device before the DRX cycle to be configured is less, the network device should configure fewer CSI measurement resources and reporting resources.
Therefore, the total sleep times of the terminal device before the DRX period to be configured can be used as the first parameter, and the resource configuration can be carried out according to the total sleep times of the terminal device before the DRX period to be configured.
In another possible implementation manner of the first aspect, the first parameter is a signal type of a power saving signal corresponding to the DRX cycle to be configured;
correspondingly, the network device obtaining a first parameter corresponding to a DRX cycle to be configured, and querying resource configuration information corresponding to the first parameter in a preset resource configuration table includes:
the network equipment acquires the signal type of the power saving signal corresponding to the DRX period to be configured, and inquires resource configuration information corresponding to the signal type in a preset resource configuration table.
Note that the Signal types of the power saving Signal may include a Wake Up Signal (WUS) Signal and a Sleep Signal (Go to Sleep Signal (GTS)).
When the signal type of the power saving signal is a WUS signal, it indicates that the terminal device needs to perform data interaction with the network device in the DRX cycle to be configured, and at this time, the network device should configure more CSI measurement resources and reporting resources; when the signal type of the power saving signal is a GTS signal, it indicates that the terminal device is in a dormant state in the DRX cycle to be configured, and does not need to perform data interaction with the network device, and at this time, the network device should configure fewer CSI measurement resources and reporting resources.
Therefore, the signal type of the power saving signal corresponding to the DRX cycle to be configured may be used as the first parameter, and the resource configuration may be performed according to the signal type of the power saving signal corresponding to the DRX cycle to be configured.
In another possible implementation manner of the first aspect, the first parameter is a current traffic volume of the terminal device;
correspondingly, the network device obtaining a first parameter corresponding to a DRX cycle to be configured, and querying resource configuration information corresponding to the first parameter in a preset resource configuration table includes:
the network equipment measures the current traffic of the terminal equipment and determines the traffic interval where the traffic is located;
and the network equipment inquires resource configuration information corresponding to the service volume interval in a preset resource configuration table.
It should be noted that the network device may count the traffic volume of the user terminal device in the traffic volume measurement period, and use the traffic volume as the current traffic volume of the terminal device. The more the current traffic of the terminal equipment is, the more data the network equipment needs to interact with the terminal equipment in the DRX period to be configured, and the more CSI measurement resources and reporting resources the network equipment should configure; the less the current traffic of the terminal device is, the less data the network device needs to interact with the terminal device in the DRX cycle to be configured, and the less CSI measurement resources and reporting resources the network device should configure.
Therefore, the current traffic of the terminal device can be used as the first parameter, and the resource configuration can be performed according to the current traffic of the terminal device.
In another possible implementation manner of the first aspect, the first parameter is a priority of a qos class identifier corresponding to a current service of the terminal device;
correspondingly, the network device obtaining a first parameter corresponding to a DRX cycle to be configured, and querying resource configuration information corresponding to the first parameter in a preset resource configuration table includes:
the network equipment acquires the priority of the service quality grade identification corresponding to the current service of the terminal equipment, and inquires resource configuration information corresponding to the priority of the service quality grade identification in a preset resource configuration table.
It should be noted that, for a service with a higher priority level, such as a GBR (Guaranteed Bit Rate) service, for a QoS Class Identifier (QoS Identifier), more CSI measurement resources and reporting resources should be configured to ensure the service quality of the service; for the service with lower QCI priority, such as Non-GBR type service, the network device may configure relatively fewer CSI measurement resources and reporting resources.
Therefore, the priority of the qos class identifier corresponding to the current service of the terminal device may be used as the first parameter, and the resource configuration may be performed according to the priority of the qos class identifier corresponding to the current service of the terminal device.
In another possible implementation manner of the first aspect, the first parameter is a distance between the terminal device and the network device;
correspondingly, the network device obtaining a first parameter corresponding to a DRX cycle to be configured, and querying resource configuration information corresponding to the first parameter in a preset resource configuration table includes:
the network equipment acquires the distance between the terminal equipment and the network equipment and determines a distance interval where the distance is located;
and the network equipment inquires resource configuration information corresponding to the distance interval in a preset resource configuration table.
It should be noted that, if the current terminal device is far away from the network device, it indicates that the terminal device may be at the cell edge. At this time, if the terminal device does not satisfy the trigger condition for exiting the DRX mode, that is, the terminal device does not satisfy the condition for cell handover or the terminal device exiting the DRX mode due to poor channel environment in a Radio Resource Control Connected (RRC _ Connected) state, the channel quality fluctuation and the time delay of the terminal device are large. At this time, if the CSI measurement resource and the reporting resource configured by the network device are few, the terminal device may not be able to report a Channel Quality Indication (CQI) in time to adjust a Modulation and Coding Scheme (MCS), and throughput performance of the network device may be affected to a certain extent.
Therefore, the distance between the terminal device and the network device can be used as a first parameter, and the resource configuration can be performed according to the distance between the terminal device and the network device.
In another possible implementation manner of the first aspect, the first parameter is a moving speed of the terminal device;
correspondingly, the network device obtaining a first parameter corresponding to a DRX cycle to be configured, and querying resource configuration information corresponding to the first parameter in a preset resource configuration table includes:
the network equipment acquires the moving speed of the terminal equipment and determines a speed interval where the moving speed is located;
and the network equipment inquires resource configuration information corresponding to the speed interval in a preset resource configuration table.
It should be noted that, if the moving speed of the terminal device is high and the terminal device does not penalize the condition of exiting the DRX mode, a situation that the terminal device has not completed CSI measurement and the terminal device has left the coverage of the original network device may occur, thereby causing network handover failure and call drop of the terminal device. Therefore, the CSI measurement resource and the reporting resource can be configured according to the moving speed of the terminal equipment. If the moving speed of the terminal equipment is higher, the network equipment should configure more CSI measurement resources and reporting resources to indicate the terminal equipment to complete CSI measurement and reporting as soon as possible, so that network switching failure and call drop are reduced; if the moving speed of the terminal device is slow, the network device can configure fewer CSI measurement resources and reporting resources relatively.
Therefore, the resource configuration can be performed according to the moving speed of the terminal device by taking the moving speed of the terminal device as the first parameter.
In a possible implementation manner of the first aspect, the sending, by the network device, the resource configuration information to a terminal device, so as to instruct the terminal device to measure and report channel state information according to the resource configuration information includes:
the network equipment packages the resource configuration information into a downlink signal of a physical downlink channel;
and the network equipment sends the downlink signal to terminal equipment through the physical downlink channel so as to instruct the terminal equipment to measure and report channel state information according to the resource configuration information.

In a possible implementation manner of the first aspect, the acquiring, by the network device, a first parameter corresponding to a DRX cycle to be configured, and querying, in a preset resource configuration table, resource configuration information corresponding to the first parameter includes:
the network equipment acquires a first parameter corresponding to each DRX period before the beginning of each DRX period, and inquires resource configuration information corresponding to the first parameter in a preset resource configuration table.
It should be noted that, each DRX cycle is regarded as a DRX cycle to be configured, and the network device can acquire CSI information in time even when the terminal device goes through a long sleep period, so that the network device has stronger robustness when transmitting high-frequency information based on beams, and reduces data scheduling delay.

The embodiment of the application can be applied to a wireless communication system. A wireless communication system is generally composed of cells (cells), each of which includes a Base Station (BS) that provides communication services to a plurality of terminal devices. The base station includes a Baseband Unit (BBU) and a Remote Radio Unit (RRU). BBU and RRU can be placed in different places, for example: RRU is remote and is placed in an open area with high telephone traffic, and BBU is placed in a central machine room. The BBU and the RRU can also be placed in the same machine room. The BBU and RRU can also be different components under one chassis.
In the embodiment of the present application, the base station is an apparatus deployed in a radio access network to provide a terminal device with a wireless communication function. The base station may include various forms of macro base stations, micro base stations (also referred to as small stations), relay stations, access points, transmission Reception Points (TRPs), and the like. In systems using different radio access technologies, names of devices having a base station function may be different, for example, in a Long Term Evolution (LTE) system, referred to as an evolved Node B (eNB or eNodeB), in a third generation (3 rd generation,3 g) system, referred to as a Node B (NB), and the like. For convenience of description, in all embodiments of the present application, the above-mentioned apparatus for providing a wireless communication function for a terminal device is collectively referred to as a network device.
The terminal devices referred to in embodiments of the present application may include various handheld devices, vehicle mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication capability. The Terminal device may also be referred to as a Mobile Station (MS), a Terminal (Terminal), and may further include a subscriber unit (subscriber unit), a cellular phone (cellular phone), a smart phone (smart phone), a wireless data card, a Personal Digital Assistant (PDA) computer, a tablet computer, a wireless modem (modem), a handheld device (handset), a laptop computer (laptop computer), a Machine Type Communication (MTC) Terminal, and the like. For convenience of description, in all embodiments of the present application, the above-mentioned devices are collectively referred to as terminal devices.
In a New Radio interface (NR) of a current Long Term Evolution (LTE) system and a fifth generation Radio access system (5th generation, 5g), a Physical Downlink Control Channel (PDCCH) detection performed by a User Equipment (UE) contributes to a considerable power consumption ratio of the UE.
The PDCCH is used for sending information for downlink, and the transmitted information includes common control information (e.g., system information, paging information, etc.) and user-specific information (downlink resource allocation indication, uplink power control parameters, etc.).
In practical applications, the data flow due to packets is usually bursty. There may be data transmission between the network device and the UE for a period of time, but there may be no data transmission for a subsequent longer period of time. Therefore, most PDCCH monitoring by the UE is without any indication detected, and the PDCCH monitoring without any indication generates considerable power consumption of the UE.
Based on the above situation, discontinuous Reception (DRX) technology is introduced in both LTE and 5G NR. In the DRX technique, when there is no data transmission, the power consumption of the UE can be reduced by stopping the UE from detecting the PDCCH and from receiving the corresponding data transmission, thereby increasing the battery lifetime of the UE.
In the DRX technique, a network apparatus on a base station side may configure a DRX cycle (DRX cycle) for a UE in a radio resource control state. As shown in fig. 2, the DRX cycle includes a time region of one listening Duration (On Duration) and a time region of discontinuous reception time (Opportunity for DRX).
During the On Duration, the UE may detect the PDCCH and/or receive a Physical Downlink Shared Channel (PDSCH). The UE starts a timer at each DRX cycle time start position (i.e., the time start position of the OnDuration), where the time length of the timer is the time length of the OnDuration, the timer may be referred to as a duration timer (DRX-onDurationTimer), and a range of the DRX-onDurationTimer may be set according to an actual situation, for example, the range of the DRX-onDurationTimer may be set to 1 to 1200ms.
As shown in fig. 3, the UE detects the PDCCH within the time range of the DRX-onDurationTimer. If the UE does not detect the PDCCH within the time range of the DRX-onDuration timer, the UE enters a sleep state after the DRX-onDuration timer expires, thereby reducing the power consumption of the UE. If the UE detects the PDCCH within the time range of the DRX-onDuration timer, the UE starts an inactivity timer (DRX-InactivetyTimer) in the DRX mechanism. If the UE continues to detect the PDCCH during the DRX-InactivetyTimer's runtime, the UE resets the inactivity timer to restart counting. If the inactivity timer is running, the UE still needs to continue detecting PDCCH even if the DRX-onDurationTimer times out until the DRX-InactivetyTimer times out.
In the DRX mechanism, there are other timers, such as DRX downlink retransmission timer (DRX-retransmission timer dl) and DRX uplink retransmission timer (DRX-retransmission timer ul). The function of these timers is however irrelevant to the solution of the embodiments of the present application and will not be described in detail here. If any of the above timers (including DRX-onDuration timer, DRX-InactivetyTimer, and others) is running, the UE will be in Active Time. In the DRX mechanism, if the UE is in Active Time, the UE needs to detect the PDCCH. Note that there are other situations that will leave the UE in Active Time, but this is not relevant to the scheme of the embodiments of the present application and will not be described in detail here.
The DRX cycle, onDuration and Opportunity for DRX are all configured to the UE by the network device on the base station side. As shown in fig. 4, the DRX cycle is divided into a short DRX cycle (short DRX cycle) and a long DRX cycle (long DRX cycle). The short DRX cycle and the long DRX cycle have different cycle lengths, and the UE switches between the DRX cycles with two different cycle lengths according to a specific rule.
Generally, when a DRX-inactivity timer times out or a DRX Media Access Control Element (MAC-CE) is received, if the UE is not configured with a short DRX cycle, the long C-DRX cycle is directly used; if the UE configures the short DRX cycle, the UE uses the short DRX cycle and starts or restarts a short DRX cycle timer (drxShortCycleTimer), and when the drxShortCycleTimer is overtime, the UE uses the long DRX cycle.
When the UE uses a short DRX cycle or a long DRX cycle, the DRX-onDurationTimer is started if the subframe number satisfies the following condition:
(SFN*N+sn)mod(short DRX cycle)＝(drxStartOffset)mod(short DRX cycle)(SFN*N+sn)mod(short DRX cycle)＝drxStartOffset
the SFN (System Frame Number) is a System Frame Number, N is a positive integer, N is a subframe Number in one SFN period, sn (subframe Number) is a subframe Number, mod is a modulo function, and drxStartOffset is a period start subframe Number.
In the practical application process of the DRX technology, because data transmission has burstiness and sparsity in time, even if the UE only performs PDCCH detection in active time of DRX, a large proportion of the UE cannot detect any indication, and the power consumption is wasted seriously. Especially in NR systems, the UE may operate at a larger radio frequency and baseband bandwidth, resulting in a higher wasted power consumption by the UE.
Based on the above, a Power Saving Signal (PoSS) is introduced in the NR Rel-16 technical standard to further reduce the UE Power consumption. Before the OnDuration of the DRX cycles, the network device at the base station side sends a PoSS to the UE to indicate whether the UE needs to wake up to perform one or more of operations of monitoring a PDCCH, receiving a PDSCH, performing measurement reporting, and the like in the next DRX cycle or DRX cycles.
The pos may be a Wake Up Signal (WUS), i.e. the UE needs to Wake Up. When the PoSS is WUS, the UE behaves as previously specified by C-DRX. Alternatively, the pos may also be a Sleep signal (Go to Sleep, GTS), that is, the UE sleeps in the next C-DRX cycle without PDCCH monitoring.
For a UE supporting WUS, the network device on the base station side may transmit WUS in Discontinuous Transmission (DTX) mode before the onsuration start position of the DRX cycle, that is, the network device on the base station side determines whether to transmit WUS on the possocession according to the requirement of the scheduling data. The UE needs to determine whether the base station sends the WUS in the pos occase. As shown in fig. 5, if the UE does not detect a WUS on the pos occase or the detected WUS indicates that the UE has no data scheduling for the corresponding OnDuration period, the UE can directly enter the sleep state without performing PDCCH monitoring. As shown in fig. 6, if the UE detects a WUS in the pos occase and the detected WUS indicates that the UE has data to schedule in the corresponding OnDuration period, the UE wakes up, and the UE may start the DRX-onDurationTimer according to the procedure specified by the previous DRX to detect the PDCCH.
Blank rectangles in fig. 6 indicate an OnDuration period, slashed rectangles indicate a DRX-inactivity timer, the UE detects a WUS on the pos occase, and the detected WUS indicates that the UE has data scheduling in the corresponding OnDuration period, the UE is gradually woken up, and starts to detect a PDCCH in the OnDuration period. And the UE detects the PDCCH, and then starts the DRX-InactivetyTimer. After the DRX-InactivetyTimer is finished, the DRX-onDuration Timer is not finished, which means that the OnDuration time period is not finished, and the PDCCH is continuously monitored. After the DRX-onDurationTimer is finished, the UE gradually enters the sleep state.
Similar to WUS, for a GTS-enabled UE, a network device on the base station side may send GTS in DTX form at a pos event preceding the OnDuration start position of the DRX cycle. The UE needs to determine whether the base station sends the GTS in the pos occasting. If the UE detects GTS on the pos occase and the detected GTS indicates that the UE has no data scheduling for the corresponding OnDuration period, the UE re-enters the sleep state. If the UE does not detect GTS on the PoSS occase or the detected GTS indicates that the UE has data scheduling in the corresponding OnDuration time period, the UE is awakened and monitors the PDCCH.
In other possible cases, the network device on the base station side may instruct the UE to enter a Sleep state or stop detecting the PDCCH for a period of time, which may be referred to as a Sleep Duration (Sleep Duration), through the GTS. As shown in fig. 7, the UE starts a DRX-inactivity timer when it detects a PDCCH within the OnDuration period. The UE detects the GTS within the duration of the DRX-InactivetyTimer, and the GTS containing the sleep time T indicates that the network equipment at the base station side does not need to schedule any data and send the PDCCH to the UE within the continuous time T after the network equipment at the base station side determines that the UE receives the GTS signal. Therefore, after detecting and analyzing the GTS including the sleep time T, the UE enters the sleep state without PDCCH detection, turns off part of the radio frequency or baseband circuit, and wakes up to detect the pos signal or PDCCH after the sleep time T. In this way, unnecessary power consumption of the UE can be reduced.
The pos may be a sequence signal or a data signal. When the pos is a data signal, the pos may be one of digital signals such as Downlink Control Information (DCI), a Physical Downlink Shared Channel (PDSCH), a Media Access Control-Control Element (MAC-CE), and a Radio Resource Control (RRC) signaling.
In the current C-DRX, the UE can only perform CSI measurement and CSI reporting at the Active time in DRX. The network device at the base station side cannot effectively obtain the CSI information to adjust the data transmission link at the beginning of the DRX cycle in time, thereby reducing the frequency band efficiency of the system and possibly increasing the power consumption of the UE due to data retransmission.
An offset time (offset duration) is usually set between the pos occase and the OnDuration, and the offset duration is used for the UE to perform processes such as the pos detection and the meaning of analyzing the indication, time-frequency synchronization, channel State Information (CSI) measurement, beam management, and the like. The more processing the UE needs to perform, the longer the time required.
In order to improve the reliability of received data, when there is data scheduling, the network device at the base station side may consider placing a reference signal at the offset duration for CSI measurement and reporting, and trigger CSI reporting based on the pos signal, thereby improving the data transmission efficiency within the OnDuration and with the next DRX cycle. The Reference Signal may be a Channel State Information Reference Signal (CSI-RS), a Demodulation Reference Signal (DM-RS), a Time/Frequency Tracking Reference Signal (TRS), a Synchronization Signal Block (SSB), or other types of Reference signals. The number of reference signals may be one or more than one.
At this time, the pos may serve as a power saving signal to instruct the UE to wake up to receive and transmit data in the current DRX cycle, or may serve as a trigger signal for CSI reporting. The network equipment at the base station side does not need a special PDCCH to trigger CSI report, and the network signaling overhead is reduced. And the CSI reporting is carried out as required, and the CSI reporting is triggered to be carried out only when the UE is awakened by the PoSS to carry out data receiving and sending, so that the measurement and reporting of the CSI are more effective, and the network equipment at the base station side can obtain timely CSI information at the active time of DRX to carry out data transmission.
However, when the network device at the base station configures the CSI measurement resource and the report resource, the same resource configuration scheme is often adopted, and a single resource configuration scheme is difficult to adapt to the differentiated UE states in the wireless communication systems such as NR, and is likely to cause too high or too low resource configuration.
In view of this, an embodiment of the present application provides a resource configuration method, in which a network device obtains a first parameter related to a DRX cycle to be configured, the first parameter is used to represent a state of the DRX cycle to be configured, and a configuration scheme of a measurement resource and a reporting resource of a channel state is determined according to the first parameter, so that reasonable resource configuration is performed according to the state of a UE, and a more reasonable and effective resource configuration scheme is implemented under the condition that power saving gain of the UE is ensured, thereby solving the problem that a single resource configuration scheme adopted in the prior art is difficult to adapt to a differentiated UE state in a wireless communication system, and resource configuration is easily too much or too little.
Next, the resource allocation method provided in the embodiment of the present application is described in detail from the perspective of the network device on the base station side. Referring to a flow chart of a resource allocation method shown in fig. 1, the method includes:
s101, a network device acquires a first parameter corresponding to a Discontinuous Reception (DRX) cycle to be configured, and inquires resource configuration information corresponding to the first parameter in a preset resource configuration table;
the DRX cycle to be configured may be set according to a configuration scheme of a user. In some possible implementations, the DRX cycle to be configured may be a DRX cycle with data transmission. In the configuration scheme, the network equipment can obtain the CSI information in the DRX period so as to configure a data transmission link, and the frequency band efficiency of the system is improved.
But this scheme only considers DRX cycles with data scheduling and does not consider DRX cycles in a sleep state. The NR system transmits high frequency information based on a beam, and at this time, if the report of the DRX cycle in the sleep state is ignored, the terminal device may have a case where the reception of high frequency signals such as a PoSS signal fails, thereby causing an increase in scheduling delay.
For example, DRX cycle 1 to DRX cycle 5 are 5 DRX cycles arranged in order on the time axis. In the DRX period 1, data interaction exists between the network equipment and the terminal equipment of the user, the DRX periods 2 to 4 are in a dormant state, and in the DRX period 5, data interaction exists between the network equipment and the terminal equipment of the user.
At this time, if only the DRX cycle with data scheduling is regarded as the DRX cycle to be configured, only the terminal device needs to perform CSI measurement and reporting in DRX cycle 1 and DRX cycle 5. However, since the terminal device goes through the sleep for 3 DRX cycles, the system state of the terminal device may change greatly, for example, the orientation of the antenna array changes, in DRX cycle 5. When the network device transmits the high-frequency information in the form of a beam, the beam has a strong directivity and a narrow coverage angle, and if the system state of the terminal device is greatly changed and the network device does not adjust the data transmission link, the network device may not transmit the pos signal or other high-frequency signals to the terminal device, which may cause the terminal device to fail to receive data, resulting in increased scheduling delay.
Therefore, in other possible implementations, the DRX cycle to be configured may be every DRX cycle, that is, the DRX cycle is considered as the DRX cycle to be configured regardless of whether the network device needs to perform data interaction with the terminal device within the DRX cycle. At this time, even if the terminal device experiences a long sleep period, the network device can acquire the CSI information in time, so that the network device has stronger robustness and reduces data scheduling delay when transmitting high-frequency information based on the beam.
For example, referring to the previous example, if each DRX cycle is considered as a DRX cycle to be configured, the network device configures CSI measurement resources for the terminal device in DRX cycles 2 to 4 even in the dormant state, and adjusts the data transmission link according to CSI (information such as Channel Quality Indication (CQI)) fed back by the terminal device, where even if the system state of the terminal device changes in DRX cycle 4, the change range of the change range is smaller than the change range of the system state of the terminal device in DRX cycles 2 to 4, and the network device can relatively accurately transmit a high-frequency signal such as a pos signal to the terminal device in DRX cycle 5, so as to improve the transmission performance of high-frequency information and reduce the data scheduling delay.
After determining the DRX cycle to be configured, the network device may obtain a first parameter corresponding to the DRX cycle to be configured. In some possible implementations, the network device may perform configuration of CSI measurement resources and reporting resources in a DRX cycle to be configured. However, in this way, the network device cannot timely and effectively obtain CSI information to adjust the data transmission link at the beginning of the DRX cycle to be configured, thereby reducing the frequency band efficiency of the system and possibly increasing the power consumption of the terminal device due to data retransmission.
In other possible implementation manners, in order to improve reliability of data reception, the network device may obtain the first parameter corresponding to the to-be-configured DRX cycle to configure the CSI measurement resource and the reporting resource before the start of the to-be-configured DRX cycle, that is, at the end of the previous DRX cycle of the to-be-configured DRX cycle (for example, at an offset duration at the end of the previous DRX cycle), so that the network device may obtain the CSI information in time before the start of the to-be-configured DRX cycle to adjust the data transmission link, improve the frequency band efficiency of the system, and reduce the power consumption of the terminal device.
The specific type of the first parameter can be set according to actual conditions. In some possible implementations, the first parameter may be a cycle length of the DRX cycle to be configured. The longer the cycle length of the DRX cycle to be configured is, the higher the possibility that data interaction occurs between the network equipment and the user terminal equipment in the DRX cycle to be configured is, and the network equipment should configure more CSI measurement resources and reporting resources; the shorter the cycle of the DRX cycle to be configured is, the lower the possibility that data interaction occurs between the network device and the user terminal device in the DRX cycle to be configured is, and the less CSI measurement resources and reporting resources should be configured by the network device. Therefore, before the DRX cycle to be configured starts, the network device may obtain a cycle length corresponding to the DRX cycle to be configured by querying a cycle configuration parameter (e.g., gnbddrxparamgroup. Longdrxcycle, gnbddrxparamgroup. Shortdrxcycle, etc.), and query resource configuration information corresponding to the cycle length in a preset resource configuration table.
In other possible implementations, the first parameter may be a cycle type of the DRX cycle to be configured. The cycle type of the terminal device may include a short DRX cycle and a long DRX cycle. When the cycle type of the DRX cycle to be configured is a short DRX cycle, the cycle length of the short DRX cycle is short, the possibility that data interaction occurs between the network equipment and the user terminal equipment in the DRX cycle to be configured is low, and the network equipment should configure less CSI measurement resources and reporting resources; when the cycle type of the DRX cycle to be configured is a long DRX cycle, the cycle length of the long DRX cycle is long, the probability that the network device performs data interaction with the user terminal device in the DRX cycle to be configured is high, and the network device should configure more CSI measurement resources and reporting resources. Therefore, before the DRX cycle to be configured starts, the network device may obtain a cycle type corresponding to the DRX cycle to be configured, and query, in a preset resource configuration table, resource configuration information corresponding to the cycle type.
In other possible implementations, the first parameter may be a total sleep time of the terminal device before the DRX cycle to be configured. If the total sleep time of the terminal equipment before the DRX period to be configured is longer, the system state change of the terminal equipment is larger, and the network equipment should be configured with more CSI measurement resources and reporting resources; if the total sleep time of the terminal device before the DRX cycle to be configured is shorter, the system state change of the terminal device is smaller, and the network device should configure fewer CSI measurement resources and reporting resources. Therefore, before the DRX cycle to be configured starts, the network device may obtain a total sleep time of the terminal device before the DRX cycle to be configured, and query, according to a sleep time interval in which the total sleep time is located, resource configuration information corresponding to the sleep time interval in a preset resource configuration table.
In other possible implementations, the first parameter may be a total number of times the terminal device sleeps before the DRX cycle to be configured. If the total sleep times of the terminal equipment before the DRX period to be configured are more, the system state change of the terminal equipment is larger, and the network equipment should configure more CSI measurement resources and reporting resources; if the total sleep times of the terminal device before the DRX cycle to be configured is less, the system state change of the terminal device is smaller, and the network device should configure fewer CSI measurement resources and reporting resources. Therefore, before the DRX cycle to be configured starts, the network device may acquire the total number of times of sleep of the terminal device before the DRX cycle to be configured, and query, in a preset resource configuration table, resource configuration information corresponding to the total number of times of sleep.
In other possible implementations, the first parameter may be a signal type of a power saving signal (pos) of the terminal device to be issued by the network device. The power saving signal is used to indicate whether the terminal device is in an awake state or a sleep state for the DRX cycle to be configured. The signal types of the power save signal may include a WUS signal and a GTS signal. When the signal type of the power saving signal is a WUS signal, it indicates that the terminal device needs to perform data interaction with the network device in the DRX cycle to be configured, and at this time, the network device may configure more CSI measurement resources and reporting resources; when the signal type of the power saving signal is a GTS signal, it indicates that the terminal device is in a dormant state in the DRX cycle to be configured, and does not need to perform data interaction with the network device, and at this time, the network device may configure fewer CSI measurement resources and reporting resources. Therefore, before the DRX cycle to be configured starts, the network device may obtain the signal type of the power saving signal corresponding to the DRX cycle to be configured, and query the resource configuration information corresponding to the signal type of the power saving signal in a preset resource configuration table.
In other possible implementations, the first parameter may be a current traffic volume of the terminal device. The network device may count the traffic volume of the ue in a traffic volume measurement period (celldrxpara. Dataamountstattimer), and use the traffic volume as the current traffic volume of the ue. When the traffic volume of the terminal device is not higher than the traffic volume threshold value (e.g., celldrxpara. Fddexdrdthd, celldrxpara. Tdldxitdhd) for exiting the DRX mode, the more the current traffic volume of the terminal device is, the more data the network device needs to interact with the terminal device in the DRX cycle to be configured, the more CSI measurement resources and reporting resources the network device should configure; the less the current traffic of the terminal device is, the less data the network device needs to interact with the terminal device in the DRX cycle to be configured, and the less CSI measurement resources and reporting resources the network device should configure. Therefore, before the DRX cycle to be configured begins, the network device may obtain the current traffic volume of the terminal device, determine the traffic volume interval in which the traffic volume is located, and query, in a preset resource configuration table, resource configuration information corresponding to the traffic volume interval.
In other possible implementations, the first parameter may be a priority of a quality of service Class Identifier (QCI) corresponding to a current service of the terminal device. In general, for a service with a higher QCI priority, such as a Guaranteed Bit Rate (GBR) class service (QCI =5,6,7,8,9,69, 70), more CSI measurement resources and reporting resources should be configured to ensure the service quality of the service; for the service with lower QCI priority, for example, the Non-Guaranteed Bit Rate (Non-GBR) class service (QCI =1,2,3,4,65, 66), the network device may configure relatively fewer CSI measurement resources and reporting resources. Therefore, before the DRX cycle to be configured begins, the network device may obtain the priority of the qos class identifier corresponding to the current service of the terminal device, and query the resource configuration information corresponding to the priority in a preset resource configuration table.
In other possible implementations, the first parameter may be a distance between the current terminal device and the network device. If the current terminal device is far away from the network device, it indicates that the terminal device may be at the cell edge. At this time, if the terminal device does not satisfy the trigger condition for exiting the DRX mode, that is, the terminal device does not satisfy the condition for cell handover or the terminal device exiting the DRX mode due to poor channel environment in a Radio Resource Control Connected (RRC _ Connected) state, the channel quality fluctuation and the time delay of the terminal device are large. At this time, if the CSI measurement resource and the reporting resource configured by the network device are few, the terminal device may not be able to report a Channel Quality Indication (CQI) in time to adjust a Modulation and Coding Scheme (MCS), and throughput performance of the network device may be affected to a certain extent. Therefore, the network device can perform configuration of the CSI measurement resource and the reporting resource according to the distance between the terminal device and the network device. Before the DRX cycle to be configured starts, the network device may query a location parameter (e.g., distbasedho. Distbasedhothd) to obtain a distance between the terminal device and the network device, determine a distance interval in which the distance is located, and query resource configuration information corresponding to the distance interval in a preset resource configuration table.
In other possible implementations, the first parameter may be a moving speed of the current terminal device. If the moving speed of the terminal device is high and the terminal device does not meet the trigger condition for exiting the DRX mode, the situation that the terminal device has not completed CSI measurement and the terminal device has left the coverage of the original network device may occur, thereby causing network handover failure and call drop of the terminal device. Therefore, the CSI measurement resource and the reporting resource can be configured according to the moving speed of the terminal equipment. If the moving speed of the terminal equipment is higher, the network equipment should configure more CSI measurement resources and reporting resources to indicate the terminal equipment to complete CSI measurement and reporting as soon as possible, so that network switching failure and call drop are reduced; if the moving speed of the terminal device is slow, the network device can configure fewer CSI measurement resources and reporting resources relatively. Therefore, before the DRX cycle to be configured begins, the network device may obtain the location change information of the terminal device in the speed measurement cycle, and calculate the current moving speed of the terminal device according to the location change information. After the network equipment acquires the current moving speed of the terminal equipment, the speed interval where the moving speed is located is determined, and resource configuration information corresponding to the speed interval is inquired in a preset resource configuration table.
It should be understood that the above description on the first parameter is only an illustrative example of the first parameter in this embodiment, and in other possible implementations, the first parameter may also be a parameter related to a DRX cycle to be configured, such as an uplink Modulation and Coding Scheme (MCS) index, an uplink data Initial packet Error Rate (IBLER) threshold, a maximum Time Advanced (TA), and the like. The specific type of the first parameter should be determined according to actual situations, and the above examples should not be construed as limiting the type of the first parameter. In addition, in the above description, although only the case where the first parameter is a certain parameter is described, the first parameter may be a certain parameter, or the first parameter may be a set of two or more parameters. For example, the first parameter may be a cycle type of a DRX cycle to be configured, and the network device queries resource configuration information corresponding to the cycle type in a preset resource configuration table; or the first parameter is the combination of the cycle type of the DRX cycle to be configured and the traffic, and the network equipment inquires resource configuration information corresponding to the cycle type and the traffic interval where the traffic is located in a preset resource configuration table.
The above mentioned resource configuration information may include one or more of configuration parameters such as time-frequency position of CSI measurement reference signals, number of CSI measurement reference signals, period of CSI measurement reference signals, time-frequency position of CSI reporting resources, number of CSI reporting resources, and period of CSI reporting resources.
The CSI measurement Reference Signal mentioned above may include one or a combination of multiple signals of a Channel State Information Reference Signal (CSI-RS), a Time/Frequency Tracking Signal (TRS), a Demodulation Reference Signal (DM-RS), a Synchronization Signal Block (SSB), and the like.
The above-mentioned CSI may include one or a combination of signals of a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Rank Indicator (RI), a Layer Indicator (LI), and the like.
The preset resource configuration table mentioned above is a resource configuration table preset by a user. The preset resource allocation table records the corresponding relationship between the first parameter and the resource allocation information. It can be understood that the user may determine the resource configuration information corresponding to each first parameter through experimental tests, theoretical calculations, and the like, so as to obtain the corresponding relationship between the first parameter and the resource configuration information, and establish the preset resource configuration table.
S102, the network equipment sends the resource configuration information to the terminal equipment so as to instruct the terminal equipment to measure and report channel state information according to the resource configuration information.
And after inquiring the resource configuration information corresponding to the first parameter from a preset resource configuration table, the network equipment sends the resource configuration information to the terminal equipment.
In some possible implementations, the resource configuration information may be a specific resource configuration scheme. And the network equipment sends the specific resource configuration scheme to the terminal equipment.
In other possible implementations, the resource configuration information may be an index. The terminal device stores the resource configuration information index table, and after the network device sends the index to the terminal device, the terminal device can query a specific resource configuration scheme from the resource configuration information index table according to the index.
In other possible implementations, the resource allocation information may be a combination of an index and a resource allocation information index table. After the network equipment sends the resource configuration information to the terminal equipment, the terminal equipment obtains the index in the resource configuration information and the resource configuration information index table, and inquires a specific resource configuration scheme from the resource configuration information index table according to the index.
In some possible implementations, the network device may encapsulate the resource configuration information into a Downlink signal in a Physical Downlink Control Channel (PDCCH) in the form of an indication bit or a signaling message, and send the Downlink signal to the terminal device through the PDCCH.
The Downlink signal may be one of Downlink Control Information (DCI), a Media Access Control-Control Element (MAC-CE), radio Resource Control (RRC) signaling, reference signal indication Information, and the like.
When the DCI message is used to carry the resource configuration information, an additional indication bit may be added to the existing DCI message. The added extra bit can be used for indicating resource configuration information, and can also indicate information such as a PoSS signal type, DRX parameters and the like.
