Description

Technical Field

[0001] This invention relates to the field of communication technology, and more specifically to a method and apparatus for allocating physical resources for discontinuous reception. Background Technology

[0002] With the large-scale deployment of 5G mobile communication New Radio (NR) technology, the power consumption problem of terminal equipment has become increasingly prominent. In order to reduce the power consumption of connected terminals, the NR standard adopts the Discontinuous Reception (DRX) mechanism. That is, when the user equipment (UE) is in the connected state, it only listens to the base station's control channel during the active time, and does not need to listen during the inactive time.

[0003] Upon detecting the base station's scheduling and control channel, the UE receives downlink service channel information or transmits uplink service channel information. During the active period, it also transmits downlink channel state (CSI) information measured using a Channel State Information Reference Signal (CSI-RS) and a Sounding Reference Signal (SRS) for measuring the uplink channel state. In other words, the UE uses the DRX mechanism to receive downlink control channel information discontinuously, allowing it to periodically enter a sleep state, ultimately achieving energy savings. Simultaneously, it reports CSI information and transmits SRS to the base station, enabling the base station to rationally schedule uplink and downlink services based on the uplink and downlink channel states, ensuring the latency and rate of each service and thus guaranteeing a superior user experience.

[0004] According to the DRX mechanism, when configuring the period and time offset of CSI-RS and SRS for the UE, the parameter configuration of the DRX activation time (onduration) (including the DRX period, DRX start time offset drx-StartOffset, and DRX activation time timer drx-onDurationTimer) needs to be considered to ensure that the UE can normally receive CSI-RS, report CSI, and send SRS. In existing technologies, configuring DRX cannot simultaneously ensure that CSI-RS, CSI reporting, and SRS transmission all fall within the DRX activation time, thus affecting one or both of CSI reporting and SRS transmission. This prevents the base station from obtaining downlink or uplink channel state information in a timely manner, consequently preventing the base station from properly scheduling the UE's downlink or uplink services and reducing downlink or uplink rates. Chinese patent application CN202110379791.3 provides a configuration based on CSI-RS and SRS, selecting a drx-StartOffset configuration to ensure that CSI-RS, CSI reporting resources, and SRS all fall within the drx-onDurationTimer period of the DRX cycle; furthermore, when they cannot all fall within the DRX drx-onDurationTimer period, the DRX drx-onDurationTimer configuration is adaptively changed. It can be seen that this method, without changing the configuration of the DRX activation timer, does not completely solve the aforementioned problem.

[0005] Chinese patent application number 201980002103.2 provides a method for receiving CSI-RS outside of the drx-onDurationTimer period of DRX. However, this method is equivalent to allowing the UE to receive CSI-RS during sleep time, which makes a significant modification to the existing standard protocol and reduces the energy-saving effect of DRX. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a physical resource allocation method and device for discontinuous reception, so as to overcome the problem that the discontinuous reception mechanism in the current New Radio standard cannot meet the actual needs.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, embodiments of this application provide a method for allocating physical resources for discontinuous reception, including: Based on the DRX activation timer configuration, the first candidate transmission time location set of the channel state reference signal is determined; Based on a basic time window, channel state information reporting resources and sounding reference signal resources are grouped to obtain multiple resource groups, and resource groups are allocated to user equipment. The duration of the basic time window is determined based on the minimum activation time of DRX, and each resource group contains at least one channel state information reporting resource and one sounding reference signal resource. Based on the resource group allocation results, the DRX start time slot for the user terminal is determined; Based on the relationship between the actual DRX activation time of the user terminal and the minimum DRX activation time, a second candidate transmission time location set for the channel state reference signal allocated to the user terminal is determined from the first candidate transmission time location set. Based on the resource group allocated to the user terminal and the actual DRX activation time of the user terminal, the channel state reference signal resources finally allocated to the user terminal are determined from the second candidate transmission time position set of the channel state reference signal. Among them, the allocation results of resource groups, the DRX start time slot of user terminals, and channel state reference signal resources are used as physical resources for user terminals to interact with base stations.

[0008] Furthermore, in some embodiments of this application, the DRX-based activation timer configuration for determining the first candidate transmission time location set of the channel state reference signal includes: The transmission period and transmission time offset of the channel state reference signal are determined from the DRX activation timer configuration. The transmission time interval of the channel state reference signal is determined based on the comparison between the minimum activation time of the DRX and the transmission period of the channel state reference signal. The first candidate transmission time location set is generated based on the transmission time offset and transmission time interval of the channel state reference signal; The first set of candidate transmission time locations includes at least one candidate transmission time location.

[0009] Furthermore, in some embodiments of this application, determining the transmission time interval of the channel state reference signal based on the comparison result between the minimum activation time of the DRX and the transmission period of the channel state reference signal includes: If the minimum activation time of DRX is less than the transmission period of the channel state reference signal, then the minimum activation time of DRX shall be used as the transmission time interval. If the minimum activation time of DRX is greater than or equal to the transmission period of the channel state reference signal, then the transmission period of the channel state reference signal shall be used as the transmission time interval.

[0010] Furthermore, in some embodiments of this application, the step of grouping channel state information reporting resources and sounding reference signal resources based on a basic time window to obtain multiple resource groups, and allocating resource groups to user equipment, includes: The target period is the greatest common multiple of the channel state information reporting period and the sounding reference signal transmission period. The duration of the basic time window is determined based on the minimum activation time of DRX; The total number of basic time windows is determined based on the target period; Within the basic time window, the total number of available channel state signal reporting resources and the total number of sounding reference signal resources are counted and grouped to obtain multiple resource groups; In a preset order, a target basic time window is determined from all basic time windows to be allocated to the user terminal, and a target resource group is determined from the target basic time window to be allocated to the user terminal.

[0011] Furthermore, in some embodiments of this application, the determination of the duration of the basic time window based on the minimum activation time of DRX includes: Determine the time slots for reporting channel state information and for probing reference signal resources; If the minimum activation time of DRX corresponds to 10 or more time slots, then the smallest positive factor of the minimum activation time of DRX that is greater than 10 will be used as the duration of the basic time window. If the minimum activation time of DRX corresponds to less than 10 time slots, then the minimum activation time of DRX will be used as the duration of the basic time window.

[0012] Furthermore, in some embodiments of this application, determining the DRX start time slot of the user terminal based on the resource group allocation result includes: Determine the basic time window index of the resource group; Based on the basic time window index, the minimum activation time of DRX, and the DRX period, the starting time slot of DRX for the user terminal is calculated and determined.

[0013] Furthermore, in some embodiments of this application, determining the second candidate transmission time position set of the channel state reference signal allocated to the user terminal from the first candidate transmission time position set based on the relationship between the actual DRX activation time of the user terminal and the minimum DRX activation time includes: The sampling interval is determined based on the ratio of the actual DRX activation time of the user terminal to the minimum DRX activation time. The first candidate transmission time location set is uniformly sampled based on the sampling interval to obtain the second candidate transmission time location set.

[0014] Secondly, embodiments of this application provide a physical resource allocation device for discontinuous reception, including a processor and a memory, wherein the processor is connected to the memory: The processor is used to call and execute the program stored in the memory; The memory is used to store the program, which is at least used to execute the above-described method for allocating physical resources for discontinuous reception.

[0015] This invention relates to the field of communication technology, specifically to a method and apparatus for allocating physical resources for discontinuous reception. The method includes: configuring a DRX activation timer to determine a first set of candidate transmission time positions for channel state reference signals; grouping channel state information reporting resources and sounding reference signal resources into multiple resource groups based on a basic time window, and allocating resource groups to user equipment; the duration of the basic time window is determined based on the minimum activation time of the DRX, and each resource group contains at least one channel state information reporting resource and one sounding reference signal resource; determining the DRX start time slot for the user terminal based on the allocation results of the resource groups; determining a second set of candidate transmission time positions for channel state reference signals allocated to the user terminal from the first set of candidate transmission time positions based on the relationship between the actual DRX activation time of the user terminal and the minimum activation time of the DRX; and determining the final channel state reference signal resources allocated to the user terminal from the second set of candidate transmission time positions for channel state reference signals based on the resource groups allocated to the user terminal and the actual DRX activation time of the user terminal. In this way, the allocation of channel state information reporting resources, sounding reference signal resources, DRX start time slots for user terminals, and channel state reference signal resources can ensure that user terminals complete all actions within the activation time, thereby ensuring normal and efficient communication and services.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0019] Figure 1 This is a flowchart illustrating the physical resource allocation method for discontinuous reception provided in an embodiment of the present invention. Please refer to [link / reference]. Figure 1 This embodiment may include the following steps: S101. Based on the DRX activation timer configuration, determine the first candidate transmission time location set of the channel state reference signal.

[0020] S102. Based on the basic time window, the channel state information reporting resources and the sounding reference signal resources are grouped to obtain multiple resource groups, and resource groups are allocated to user equipment.

[0021] The duration of the basic time window is determined based on the minimum activation time of the DRX, and each resource group contains at least one channel state information reporting resource and one sounding reference signal resource.

[0022] S103. Based on the resource group allocation results, determine the DRX start time slot for the user terminal.

[0023] S104. Based on the relationship between the actual DRX activation time of the user terminal and the minimum activation time of the DRX, determine the second candidate transmission time position set of the channel state reference signal to be allocated to the user terminal from the first candidate transmission time position set.

[0024] S105. Based on the resource group allocated to the user terminal and the actual DRX activation time of the user terminal, determine the channel state reference signal resources finally allocated to the user terminal from the second candidate transmission time position set of the channel state reference signal.

[0025] In this way, through the allocation of resource groups, the allocation of channel state information reporting resources and a sounding reference signal resource can be realized, as well as the allocation of DRX start time slot and channel state reference signal resources in conjunction with the user terminal. This completes the allocation of physical resources for all discontinuous reception, allowing the user terminal to interact with the base station. It can ensure that each UE has the above-mentioned physical resources during the activation time without modifying the existing communication standard. This solves the problem in the existing technology where one or more of the CSI reporting resources, SRS resources and CSI-RS resources allocated to some UEs fall outside the DRX activation time, causing the inability to guarantee CSI reporting or uplink channel sounding, thus leading to performance degradation.

[0026] Furthermore, in some embodiments of this application, determining a first candidate transmission time position set for the channel state reference signal based on the DRX activation time timer configuration includes: determining the transmission period and transmission time offset of the channel state reference signal from the DRX activation time timer configuration; determining the transmission time interval of the channel state reference signal based on the comparison result between the minimum activation time of the DRX and the transmission period of the channel state reference signal; and generating a first candidate transmission time position set based on the transmission time offset and transmission time interval of the channel state reference signal; wherein the first candidate transmission time position set contains at least one candidate transmission time position.

[0027] Specifically, the CSI-RS transmission period is first denoted as... The CSI-RS transmission time offset is Furthermore, when multiple DRX activation timers (drx-onDurationTimer) are configured, the minimum activation time of the drx-onDurationTimer is the minimum activation time for the DRX. Transmission period of CSI-RS (Channel State Reference Signal) To determine the first set of candidate transmission time locations for sending CSI-RS, specifically including: First, determine the CSI-RS transmission time interval. Specifically, if the minimum activation time of the DRX is less than the transmission period of the channel state reference signal, then the minimum activation time of the DRX is used as the transmission time interval; if the minimum activation time of the DRX is greater than or equal to the transmission period of the channel state reference signal, then the transmission period of the channel state reference signal is used as the transmission time interval.

[0028] If Then Determined as the CSI-RS transmission time interval Based on this, the first candidate transmission time location set R of CSI-RS can be represented as:

[0029] Where P represents the number of candidate transmission time positions for CSI-RS, and the specific calculation formula is as follows:

[0030] Otherwise, As the transmission interval of CSI-RS Based on this, the first candidate transmission time location set R of CSI-RS can be represented as:

[0031] in, It can be configured manually or automatically.

[0032] Figure 2 This is a schematic diagram of the resource group allocation process in the physical resource allocation method for discontinuous reception provided in this embodiment of the invention, as shown below. Figure 2 As shown, in some embodiments of this application, the channel state information reporting resources and sounding reference signal resources are grouped based on a basic time window to obtain multiple resource groups, and resource groups are allocated to user equipment, including: S201. The greatest common multiple of the channel state information reporting period and the probe reference signal transmission period shall be used as the target period.

[0033] Specifically, calculate the least common multiple of the CSI reporting period and the SRS transmission period. And this was determined as the target period.

[0034] S202. Determine the duration of the basic time window based on the minimum activation time of DRX.

[0035] In some embodiments, the time slots for channel state information reporting resources and the time slots for probe reference signal resources can be determined first; if the time slots corresponding to the minimum activation time of the DRX are greater than or equal to 10, then the smallest positive factor greater than 10 of the minimum activation time of the DRX is used as the duration of the basic time window (hereinafter used). (This is indicated by the formula). If the minimum activation time of the DRX corresponds to less than 10 time slots, then the minimum activation time of the DRX will be used as the duration of the basic time window.

[0036] It should be noted that the duration of the basic time window can be related to the frame structure, the time slot of the CSI reporting resource, and the time slot configuration of the SRS resource, so as to ensure that each basic time window contains at least one CSI reporting resource (i.e., the time slot of the CSI reporting resource) and at least one SRS resource (i.e., the time slot of the SRS resource).

[0037] S203. Determine the total number of basic time windows based on the target period.

[0038] Specifically, the total number of basic time windows The solution formula is expressed as:

[0039] S204. Within the basic time window, count the total number of available channel state signal reporting resources and the total number of sounding reference signal resources, and group them to obtain multiple resource groups.

[0040] Specifically, the total number of CSI reporting resources and SRS resource groups that can be allocated to the UE within each basic time window is counted. For example, if one CSI reporting resource and one SRS resource in a basic time window are defined as a resource group, then the total number of resource groups in a basic time window is... The solution formula is expressed as:

[0041] In the formula, and These represent the total number of CSI-reported resources and the total number of SRS resources within a basic time window, respectively.

[0042] It should be noted that the data for the CSI reported resources and SRS resources mentioned above involve dimensions such as time division, frequency division, code division, and comb division.

[0043] S205. According to a preset order, determine the target basic time window to be allocated to the user terminal from all basic time windows, and determine the target resource group to be allocated to the user terminal from the target basic time window.

[0044] Specifically, the total number of basic time windows in the target period is: The total number of CSI reports and SRS resource groups for a basic time window is Then the number of resource groups that can be allocated to a UE is .

[0045] As can be seen, the resources to be allocated are described by two dimensions: the basic time window and the resource group within the window. Thus, when allocating resources, one of the dimensions can be selected for priority allocation, with the basic time window dimension being the priority dimension.

[0046] Thus, resource groups allocated to the UE in a preset order (such as the default order in the system) can be represented as follows: ,in, The basic time window for index i , This shows the resource group with index j in the basic time window with index i. .

[0047] It should be noted that when it is not necessary to allocate CSI reporting resources to the UE, SRS resources can still be allocated to it from the above resource groups.

[0048] Based on this, in this embodiment of the application, the starting time slot of the DRX for the user terminal is determined based on the allocation result of the resource group, including: determining the basic time window index of the resource group; and calculating and determining the starting time slot of the DRX for the user terminal based on the basic time window index, the minimum activation time of DRX, and the DRX period. The specific calculation formula is expressed as follows:

[0049] Where i is the index of the basic time window in which the resource group is located. The DRX period is represented by "mod"; "mod" indicates the modulo operation. It is understandable that, in practical applications, the determined DRX start time slot for a UE can be represented and transmitted based on an index format set by the system.

[0050] Based on this, in this embodiment of the application, a second candidate transmission time position set for the channel state reference signal allocated to the user terminal is determined from the first candidate transmission time position set based on the relationship between the actual DRX activation time of the user terminal and the minimum activation time of the DRX. This includes: determining a sampling interval based on the ratio of the actual DRX activation time of the user terminal to the minimum activation time of the DRX; and uniformly sampling the first candidate transmission time position set based on the sampling interval to obtain the second candidate transmission time position set.

[0051] Specifically, firstly, based on the UE's actual DRX activation time And the minimum activation time of the DRX mentioned above for determining the first candidate transmission time location set, i.e. The second candidate transmission time location set W is determined from the first candidate transmission time location set R. The specific solution formula is expressed as follows:

[0052]

[0053] Where i = 0, 1, ..., P / Q.

[0054] Based on this, in the embodiments of this application, the channel state reference signal resources finally allocated to the user terminal can be determined from the second candidate transmission time position set of the channel state reference signal based on the resource group allocated to the user terminal and the actual DRX activation time of the user terminal. The specific solution formula is expressed as follows: .

[0055] It is understandable that, in practical applications, the channel state reference signal resources ultimately allocated to user terminals can be represented and transmitted in the form of an index based on system settings.

[0056] The physical resource allocation method for discontinuous reception provided in this application obtains a set of candidate transmission time positions for CSI-RS by grouping CSI reporting resources and SRS resources and combining them with the DRX activation time. This determines the CSI reporting resources, SRS resources, and CSI-RS resources allocated to the UE. Without modifying the existing communication standard, this method ensures that each UE has the aforementioned physical resources during the activation time. It solves the problem in the prior art where one or more of the CSI reporting resources, SRS resources, and CSI-RS resources allocated to some UEs fall outside the DRX activation time, causing the inability to guarantee CSI reporting or uplink channel detection, thus leading to performance degradation.
