Description

Electronic device, wireless communication method, and computer-readable storage medium

Technical Field

Embodiments of the present disclosure relate generally to the field of wireless communications, and in particular, to electronic devices, wireless communication methods, and computer-readable storage media. More particularly, the present disclosure relates to an electronic device as a user equipment in a wireless communication system, an electronic device as a resource management device in a wireless communication system, a wireless communication method performed by a user equipment in a wireless communication system, a wireless communication method performed by a resource management device in a wireless communication system, and a computer-readable storage medium.

Background

In the LTE system, the Scheduling modes of a base station for a UE (User Equipment) mainly include dynamic Scheduling and Semi-Persistent Scheduling (SPS). In the dynamic Scheduling scheme, when the UE needs to send data and there is no uplink resource, a Scheduling Request (SR) is sent to notify the base station that there is uplink data to send, and the base station schedules related resources after receiving the SR for the UE to feed back a Buffer Status Report (BSR), and then the base station schedules corresponding uplink resource to send data to the UE according to the BSR sent by the UE. For a periodic packet service, the base station may obtain the size and the period of the service of the UE by observing statistics, and then may schedule a plurality of uplink resources to the UE for sending uplink data, and an interval between different uplink resources may be indicated by RRC (Radio Resource Control) signaling. This manner of scheduling is referred to as semi-persistent scheduling. Since the size of the element indicating the time interval in RRC signaling is limited, the number of time intervals that can be carried is limited.

As NR (New Radio) communication systems provide communication support for more and more services, the diversity of the service transmission requirements also poses certain challenges for the current NR communication systems. For example, Ultra-reliable and Low Latency Communications (urrllc) services place high demands on the Latency and reliability of data transmission. The UE needs to periodically transmit some control information in the manner of urrllc, and such transmission is usually uplink transmission, and the amount of data per transmission is small. Because the time interval supported by the existing standard is limited, the period for configuring the uplink resource is not matched with the actual period of the service, thereby causing a larger transmission delay and resource waste.

Therefore, it is necessary to provide a technical solution to support more various cycles, so as to reduce the transmission delay of the periodic data and more effectively utilize the resources.

Therefore, the periodic information reported by the electronic equipment can support various periods, so that the period of resource allocation of the electronic equipment is matched with the actual period of the service, the transmission delay of the periodic service can be reduced, and the utilization rate of the resource can be improved.

<1. review >

As mentioned above, for the periodic uplink transmission with a small amount of transmission time and a high requirement on transmission delay, because the time interval supported by the existing standard is limited, the period for configuring the uplink resource will not match the actual period of the service, thereby resulting in a large transmission delay and causing a waste of resources.

For example, the frequency of transmitting the traffic data is 60Hz (i.e. the period of transmitting the traffic data is 16.67ms), and resource allocation periods of 10ms and 20ms are supported in the existing standard. Here, it is assumed that the resource management device sets the resource allocation period to 10 ms. Then, the data arrival time, the time domain position of the allocated resource, and the data transmission delay are shown in the following table.

TABLE 1

As can be seen from the above table, data arrives at 16.67ms, but since the allocated resources are at the positions of 10ms and 20ms, no data is transmitted at the position of 10ms, resulting in waste of resources, and data arriving at 16.67ms is transmitted at the position of 20ms, resulting in a delay of 3.33 ms. Similarly, data arrives at 33.34ms, but since the allocated resources are at the positions of 30ms and 40ms, no data is transmitted at the position of 30ms, resulting in waste of resources, and data arriving at 33.34ms is transmitted at the position of 40ms, resulting in a delay of 6.66 ms.

Therefore, as the supported period in the existing standard is limited, the allocation period of the resource is not matched with the actual period of the service, which causes the waste of the resource, thereby reducing the utilization rate of the resource and increasing the time delay of data transmission.

The present disclosure proposes, for such a scenario, an electronic device in a wireless communication system, a wireless communication method performed by the electronic device in the wireless communication system, and a computer-readable storage medium to support a wider variety of cycles, thereby reducing transmission delay of periodic data and more efficiently utilizing resources.

The resource management device according to the present disclosure may be a network side device that performs resource management on user equipment within a coverage area. In addition, the resource management device may also be a user device that performs resource management on other user devices. For example, the resource management device may be a cluster head device of a cluster composed of a plurality of user equipments, and performs resource management on other user equipments in the cluster.

The wireless communication system according to the present disclosure may be an NR communication system.

The network side device according to the present disclosure may be any type of TRP (Transmit and Receive Port), or may be a base station device, such as eNB, or may be a gbb (base station in a 5 th generation communication system).

The user equipment according to the present disclosure may be a mobile terminal such as a smart phone, a tablet Personal Computer (PC), a notebook PC, a portable game terminal, a portable/cryptographic dog-type mobile router, and a digital camera device, or a vehicle-mounted terminal such as a car navigation apparatus. The user equipment may also be implemented as a terminal (also referred to as a Machine Type Communication (MTC) terminal) that performs machine-to-machine (M2M) communication. Further, the user equipment may be a wireless communication module (such as an integrated circuit module including a single chip) mounted on each of the above-described terminals.

<2. configuration example of user equipment >

Fig. 1 is a block diagram illustrating an example of a configuration of an electronic apparatus 100 according to an embodiment of the present disclosure. The electronic device 100 herein may be a user equipment in a wireless communication system.

As shown in fig. 1, the electronic device 100 may include a traffic information generation unit 110, a decoding unit 120, a determination unit 130, and a communication unit 140.

Here, the respective units of the electronic device 100 may be included in the processing circuit. The electronic device 100 may include one processing circuit or may include a plurality of processing circuits. Further, the processing circuitry may include various discrete functional units to perform various different functions and/or operations. It should be noted that these functional units may be physical entities or logical entities, and that units called differently may be implemented by the same physical entity.

According to the embodiment of the present disclosure, the traffic flow information generating unit 110 is configured to generate traffic flow information of the electronic device 100, where the traffic flow information includes periodicity information of traffic data transmitted by the electronic device 100.

According to an embodiment of the present disclosure, the electronic device 100 may transmit the traffic information generated by the traffic generation unit 110 to the resource management device through the communication unit 140. Here, the resource management device is used to manage resources of the electronic device 100, including allocating resources for transmitting data to the electronic device 100. The resource management device may be, for example, a network side device or other user equipment.

According to an embodiment of the present disclosure, the electronic device 100 may receive resource allocation information from the resource management device through the communication unit 140.

According to an embodiment of the present disclosure, the decoding unit 120 may descramble the resource allocation information, thereby obtaining the resource allocation information if the descrambling is successful.

According to an embodiment of the present disclosure, in a case where the decoding unit 120 descrambles the resource allocation information successfully using the specific RNTI, the determining unit 130 may determine a period in which the resource management device allocates the resource to the electronic device 100 according to periodicity information included in the traffic information generated by the traffic information generating unit 110.

As can be seen from this, according to the electronic device 100 of the embodiment of the present disclosure, the periodicity information of the service data may be sent to the resource management device, and in the case that descrambling the resource allocation information with the specific RNTI is successful, it may be determined that the period in which the resource management device allocates the resource to the electronic device 100 is determined according to the periodicity information. That is, the electronic device 100 does not need to receive, from the resource management device, a period in which the resource management device allocates the resource to the electronic device 100, that is, a period in which the resource management device implicitly indicates that the resource is allocated to the electronic device 100. In this way, since the periodic information reported by the electronic device 100 can support more kinds of periods, the period of resource allocation by the electronic device 100 matches with the actual period of the service, so that the transmission delay of the periodic service can be reduced, and the utilization rate of the resource can be improved.

According to the embodiment of the present disclosure, in the case that there is no service data to be transmitted in the logical channel, the service traffic information generating unit 110 may generate the service traffic information, and may transmit the service traffic information to the resource management device through the communication unit 140.

According to an embodiment of the present disclosure, as shown in fig. 1, the electronic device 100 may further include a scheduling request information generating unit 150 for generating scheduling request information.

According to an embodiment of the present disclosure, in a case that there is no traffic data to be transmitted in a logical channel, the scheduling request information generating unit 150 may generate scheduling request information, and the electronic device 100 may transmit the generated scheduling request information to the resource management device through the communication unit 140. Here, the scheduling request information may be used to request resources for transmitting traffic flow information.

According to an embodiment of the present disclosure, the electronic device 100 may receive, from the resource management device, a resource for transmitting traffic information, which the resource management device allocates in response to the scheduling request information, through the communication unit 140. Next, the electronic device 100 may transmit the traffic information to the resource management device using the resource for transmitting the traffic information.

In the prior art, the scheduling request information is transmitted to the resource management device only when there is traffic data to be transmitted in the logical channel. And the resource management device can only obtain the periodic information of the service data sent by the electronic device according to observation statistics. If the resource management device does not receive the request sent by the electronic device, the electronic device needs to repeatedly send the scheduling request until the resource management device allocates the corresponding resource, which results in a long time delay.

According to the embodiment of the disclosure, the scheduling request information and the service traffic information can be sent to the resource management device under the condition that no service data to be sent exists in the logical channel. In addition, the electronic device 100 may actively report the periodicity information of the service data transmitted by the electronic device. Thus, before the service data to be transmitted in the logical channel, the resource management device may allocate the resource to the electronic device 100 according to the periodic information of the service data transmitted by the electronic device 100, thereby reducing the delay.

According to an embodiment of the present disclosure, the electronic device 100 may utilize a MAC (Media Access Control) CE (Control Element) to carry service traffic information. For example, the electronic device 100 may carry the service traffic information in a BSR (Buffer Status Report) in the MAC CE.

According to an embodiment of the present disclosure, the periodicity information may indicate a period of the service data transmitted by the electronic device 100, and may include, for example, the period of the service data transmitted by the electronic device 100 or a frequency of the service data transmitted by the electronic device 100. Here, the period may be the inverse of the frequency, and thus the period for transmitting traffic data may be estimated from the frequency for transmitting traffic data.

According to the embodiment of the present disclosure, for any service, the electronic device 100 may select a parameter that is an integer from the period and the frequency, and use the parameter as the periodicity information. For example, assuming that the period of one service is 33.333ms and the frequency is 3Hz, the electronic device 100 includes the frequency 3Hz as the periodicity information in the service traffic information.

According to an embodiment of the present disclosure, in the case of carrying a period or a frequency using periodic information, a greater number of periods or frequencies may be supported. For example, electronic device 100 may support any integer period in the range of 1-1023ms, or any integer frequency in the range of 1-1023Hz, as periodic information.

According to an embodiment of the present disclosure, the traffic flow information may further include indication information indicating whether the periodicity information is periodic or frequency. For example, the indication information may be represented by 1 bit, and when the indication information is 1, it represents that the periodicity information is a period, and when the indication information is 0, it represents that the periodicity information is a frequency.

According to an embodiment of the present disclosure, the service traffic information may further include size information of the cached service data. Here, since the electronic device 100 may transmit the traffic flow information in a case where there is no traffic data to be transmitted in the logical channel, the size of the buffered traffic data may be 0.

According to an embodiment of the present disclosure, as shown in fig. 1, the electronic device 100 may further include an estimating unit 160 for estimating an arrival time of the traffic data. For example, the electronic device 100 may estimate the time of the upcoming arrival of the traffic data according to the size and period of the upcoming traffic data. Further, the traffic flow information may also include information of the arrival time of the traffic data predicted by the estimating unit 160.

As described above, the traffic flow information may include periodic information of the traffic data transmitted by the electronic device 100. Optionally, the service traffic information further includes at least one of the following: indication information indicating whether the periodicity information is periodic or frequency, size information of the buffered traffic data, and expected arrival time information of the traffic data.

Fig. 2 is a schematic diagram illustrating the contents of traffic flow information according to an embodiment of the present disclosure. As shown in fig. 2, the 1-bit indication information indicates whether a period or a frequency is included in the traffic information, the 1 st part of the 7-bit frequency/period indicates the frequency or the content of the 1 st part of the period, the 2 nd part of the 8-bit frequency/period indicates the content of the 2 nd part of the frequency or the period, that is, the frequency or the period can be indicated by 15 bits at most, the arrival time information of 4 bits indicates the arrival time information of the traffic data estimated by the estimation unit 160, and the size information of 4 bits indicates the size of the buffered traffic data.

According to an embodiment of the present disclosure, the electronic device 100 may receive resource allocation Information from the resource management device through DCI (Downlink Control Information). Therefore, in the following, the resource allocation information is explained by taking DCI as an example.

In the existing scheme, in the SPS scheduling manner, the DCI transmitted by the resource management device at least includes frequency domain resources allocated to the electronic device 100 for transmitting service data in each period and time domain resources allocated to the electronic device 100 for transmitting service data for the first time. Further, the resource management device may also transmit RRC signaling including periodic information allocating resources for the electronic device 100 to the electronic device 100. That is, the resource management device indicates the period of allocating resources in an explicit manner. In addition, the resource management device may scramble the DCI with the RNTI corresponding to the SPS scheduling manner, and the electronic device 100 may descramble the DCI with the corresponding RNTI to determine that the scheduling manner is the SPS and acquire content in the DCI. In this way, the electronic device 100 may determine resources for transmitting traffic data at each period through frequency domain resources for transmitting traffic data at each period and time domain resources for transmitting traffic data for the first time included in the DCI, and periodicity information included in the RRC signaling.

According to an embodiment of the present disclosure, the RRC signaling transmitted by the resource management device may not include periodicity information for allocating resources for the electronic device 100. That is, the resource management device indicates the period of allocating resources in an implicit manner. In addition, the resource management device may scramble the DCI with a specific RNTI. This specific RNTI is a newly set RNTI, and is different from an RNTI corresponding to an SPS scheduling method in the existing scheme. That is, such a specific RNTI corresponds to resource allocation information in the case where the RRC signaling does not include periodic information in the SPS scheduling scheme.

According to an embodiment of the present disclosure, for the SPS scheduling manner, the electronic device 100 may receive an RRC signaling that includes periodic information that the resource management device allocates resources to the electronic device 100, or may receive an RRC signaling that does not include periodic information that the resource management device allocates resources to the electronic device 100. Therefore, after the electronic device 100 receives the resource allocation information, the resource allocation information may be descrambled using an RNTI (second type RNTI in table 2) corresponding to the resource allocation information in the case where the RRC signaling includes the periodicity information in the SPS scheduling scheme, or the resource allocation information may be descrambled using an RNTI (third type RNTI in table 2) corresponding to the resource allocation information in the case where the RRC signaling does not include the periodicity information in the SPS scheduling scheme. In a case where the electronic device 100 successfully descrambles the resource allocation information using the RNTI corresponding to the resource allocation information in a case where the periodic information is included in the RRC signaling, the electronic device 100 may determine a period for which the resource management device allocates the resource based on the periodic information included in the RRC signaling; in the case where the electronic device 100 successfully descrambles the resource allocation information using the RNTI corresponding to the resource allocation information in the case where the periodicity information is not included in the RRC signaling, the electronic device 100 may determine a period for which the resource management device allocates the resource based on the periodicity information included in the traffic flow information.

According to an embodiment of the present disclosure, the RNTI scrambling the resource allocation information may have the following three types:

TABLE 2

In table 2, the first RNTI and the second RNTI are RNTIs in the existing scheme, and the third RNTI is an RNTI newly added in the present disclosure, and is used for scrambling and descrambling resource allocation information in the SPS scheduling manner under the condition that the RRC signaling does not include periodic information.

As described above, in the case where the RRC signaling includes the periodic information, since resources indicating the periodic information in the RRC signaling are limited, the number of supported periods is limited. In case that the RRC signaling does not include periodicity information, a large number of cycles can be supported since the period of resource allocation can be implicitly indicated. That is, the number of periods supported in the case where the periodicity information is not included in the RRC signaling is different from the number of periods supported in the case where the periodicity information is included in the RRC signaling. More specifically, the number of cycles supported in the case where the periodicity information is not included in the RRC signaling is greater than the number of cycles supported in the case where the periodicity information is included in the RRC signaling.

According to the embodiment of the present disclosure, the determining unit 130 may further determine the resource for the electronic device 100 to transmit the service data in each period according to the resource allocation information and the period in which the resource management device allocates the resource to the electronic device 100.

According to an embodiment of the present disclosure, the resource allocation information may include frequency domain resources for the electronic device 100 to transmit the service data in each period and time domain resources for the electronic device 100 to transmit the service data for the first time, and therefore the determining unit 130 may determine the frequency domain resources for the electronic device 100 to transmit the service data in each period and the time domain resources for the electronic device 100 to transmit the service data for the first time according to the resource allocation information.

According to an embodiment of the present disclosure, the determining unit 130 may determine the time domain resource for transmitting the service data at each period according to the time domain resource for transmitting the service data for the first time and the period in which the resource management device allocates the resource to the electronic device 100. Thereby, the determining unit 130 may determine the time domain resource and the frequency domain resource in which the electronic device 100 transmits the traffic data at each period.

According to the embodiment of the present disclosure, since the periodicity information may include the period of the service data transmitted by the electronic device 100, it may also include the frequency of the service data transmitted by the electronic device 100.

In the case where the periodicity information includes periods of the traffic data transmitted by the electronic device 100, the determining unit 130 may determine the time domain resources transmitting the traffic data at the respective periods according to the following formula:

tn＝t1+T×(n-1)

where tn denotes a time domain resource for transmitting traffic data in an nth (n is a positive integer) period, and is expressed in ms, and t1 denotes a time domain resource for transmitting traffic data for the first time, and is expressed in ms, and can be obtained from resource allocation information. T denotes a period in which the electronic device 100 transmits the traffic data, and has a unit of ms.

In the case where the periodicity information includes the frequency of the traffic data transmitted by the electronic device 100, the period calculated from the frequency may not be an integer multiple of the minimum unit in which the resource management device allocates the time domain resource. For example, if the periodicity information includes that the frequency of the service data transmitted by the electronic device 100 is 60GHz, the periodicity of the service data transmitted by the electronic device calculated according to the frequency is 16.666ms, and the minimum unit for allocating the time domain resource by the resource management device is 1ms, so that 16.666ms is not an integer multiple of 1 ms.

According to an embodiment of the present disclosure, in the case that the period of allocating resources is not an integer multiple of the minimum unit of the resource management device allocating time domain resources, the determining unit 130 may adjust the time domain resources transmitting traffic data at each period to an integer multiple of the minimum unit.

According to an embodiment of the present disclosure, the determining unit 130 may determine a time to transmit traffic data in each period according to a time domain resource in which the traffic data is first transmitted and a period in which the resource is allocated, and adjust the time to an integer multiple of a minimum unit by rounding the time up.

For example, the determining unit 130 may determine the time domain resource for transmitting the traffic data at each period according to the following formula:

tn＝t1+cell(1000/f×(n-1))

where tn denotes a time domain resource for transmitting traffic data in an nth (n is a positive integer) period, and is expressed in ms, and t1 denotes a time domain resource for transmitting traffic data for the first time, and is expressed in ms, and can be obtained from resource allocation information. f denotes the frequency of the electronic device 100 transmitting the traffic data, and has a unit of GHz. 1000/f represents the period in ms in which the resource management device allocates resources to the electronic device 100. The cell represents a rounding up operation. Here, since t1 is an integer, the above equation can also be written as:

tn＝cell(t1+1000/f×(n-1))

where t1+1000/f × (n-1) represents a time at which the determining unit 130 transmits traffic data at each period determined from the time domain resource at which the traffic data is transmitted for the first time and the period at which the resource is allocated, and the determining unit 130 adjusts the time to an integer multiple of the minimum unit by rounding the time up.

For example, assuming that f is 60GHz, t1 is 1ms, t2 is 18ms, t3 is 35ms, t4 is 51ms, and so on.

As described above, according to the embodiment of the present disclosure, the determining unit 130 may first determine the time for transmitting the traffic data in each period according to the time domain resource for transmitting the traffic data for the first time and the period for allocating the resource, and then adjust the time to be an integer multiple of the minimum unit. Thus, the resources allocated by the resource management device to the electronic device 100 are not strictly periodic resources, and may be slightly biased. For example, in the above example, t1 is separated from t2 by 17ms, t2 is separated from t3 by 17ms, and t3 is separated from t4 by 16 ms.

According to an embodiment of the present disclosure, the determining unit 130 may also adjust the period to be an integer multiple of the minimum unit by rounding up the period of the allocated resources, and then determine the time domain resources for transmitting the traffic data at each period according to the time domain resources for transmitting the traffic data for the first time and the adjusted period.

tn＝t1+(n-1)×cell(1000/f)

similarly, tn denotes a time domain resource for transmitting traffic data at an nth (n is a positive integer) period, and has a unit of ms, and t1 denotes a time domain resource for transmitting traffic data for the first time, and has a unit of ms, which can be obtained from the resource allocation information. f denotes the frequency of the electronic device 100 transmitting the traffic data, and has a unit of GHz. 1000/f represents the period in ms in which the resource management device allocates resources to the electronic device 100. The cell represents a rounding up operation.

In the above formula, cell (1000/f) indicates that the period obtained by rounding up the period of the allocated resources by the determining unit 130 is an integer multiple of the minimum unit, and then the determining unit 130 determines the time domain resources for transmitting the traffic data in each period according to the time domain resources for transmitting the traffic data for the first time and the adjusted period.

For example, assuming that f is 60GHz, t1 is 1ms, and the adjusted period is 17ms, therefore t2 is 18ms, t3 is 35ms, t4 is 52ms, and so on.

As described above, since determining section 130 adjusts the period of resource allocation to be an integer multiple of the minimum unit and calculates the time domain resource for transmitting the traffic data in each period, the resource allocated to electronic apparatus 100 by the resource management apparatus is a strictly periodic resource.

As described above, according to the embodiments of the present disclosure, in the case that the period for allocating resources is not an integer multiple of the minimum unit for allocating time domain resources by the resource management device, the electronic device 100 may agree with the resource management device in such a manner that the time domain resources for transmitting traffic data in each period are adjusted to be integer multiples of the minimum unit for allocating time domain resources, so that the resources allocated to the electronic device 100 determined by the electronic device 100 and the resources allocated to the electronic device 100 determined by the resource management device are kept identical. In this way, even if the RRC signaling does not include the resource allocation cycle, the electronic apparatus 100 can determine the resource allocated thereto in a manner consistent with the resource management apparatus.

According to an embodiment of the present disclosure, as shown in fig. 1, the electronic device 100 may further include a data generating unit 170 for generating traffic data to be transmitted. Further, in the case of service data to be transmitted in the logical channel, the electronic device 100 may transmit the service data through the communication unit 140 according to the resource, determined by the determination unit 130, of the electronic device 100 to transmit the service data at each cycle.

Fig. 3 is a signaling flow diagram illustrating requesting uplink resources and transmitting data by a user equipment according to an embodiment of the present disclosure. In fig. 3, the UE may be implemented by the electronic device 100. As shown in fig. 3, in step S301, when the traffic data has not yet reached the logical channel, the UE transmits scheduling request information to the resource management device. Next, in step S302, the resource management device may allocate uplink resources for transmitting traffic flow information to the UE. Next, in step S303, the UE transmits traffic information using the uplink resource allocated by the resource management device. Next, in step S304, the resource management device allocates resources for transmitting uplink data to the UE, for example, through the resource allocation information, so that the UE can determine the resources for transmitting traffic data in each period through the embodiments of the present disclosure. Next, in step S305, when the traffic data arrives at the logical channel, the UE transmits uplink data to the resource management device according to the resource for transmitting the traffic data in each determined cycle. Here, although fig. 3 shows a case where the UE transmits uplink data to the resource management device, the UE may actually transmit uplink data to other devices.

According to an embodiment of the present disclosure, before the electronic device 100 transmits the traffic information to the resource management device, the electronic device 100 may further transmit a BSR (hereinafter referred to as a first BSR) to the resource management device to notify the resource management device that the electronic device 100 desires to apply for a resource in advance for data that has not reached a logical channel.

Fig. 4 is a schematic diagram illustrating the contents of a first cache status report according to an embodiment of the present disclosure. Fig. 4 shows the case of a short BSR (i.e. only one logical channel). In fig. 4, the logical channel ID indicates an identifier of a logical channel to which the BSR is directed, and the buffer size indicates the size of the buffered traffic data. Since the traffic data has not yet arrived at the logical channel, it may be 0 here.

Fig. 5 is a schematic diagram illustrating the contents of a first cache status report according to an embodiment of the present disclosure. Fig. 5 shows the case of a long BSR (i.e. there are multiple logical channels). In FIG. 5, the LCG₀-LCG₇Each indicates whether there is data transmission in a corresponding logical channel of the 8 logical channels. For example, LCG ₀1 indicates that there is data transmission in the logical channel numbered 0, LCG₁0 means that no data is transmitted in the logical channel numbered 1, and so on. Buffer size 1, buffer size 2, and buffer size … buffer size m indicates the size of the buffer data in each logical channel to which data is transferred, and m indicates the LCG₀-LCG₇Is the number of 1 s. For example, suppose LCG₀、LCG₁、LCG₂、LCG₅Is 1, LCG₃、LCG₄、LCG₆、LCG₇When m is 0, the buffer size 1 indicates the size of the buffer data in the logical channel numbered 0, the buffer size 2 indicates the size of the buffer data in the logical channel numbered 1, the buffer size 3 indicates the size of the buffer data in the logical channel numbered 2, and the buffer size 4 indicates the size of the buffer data in the logical channel numbered 5. Since the traffic data has not yet arrived at the logical channel, all the buffer sizes may be set to 0, LCG₀-LCG₇Also set to 0, or all buffer sizes may be set to 0, LCG₀-LCG₇Is set to 1.

According to the embodiment of the present disclosure, the resource management device does not consider that an exception occurs when receiving the first BSR shown in fig. 4 or fig. 5, but may determine that the electronic device 100 desires to apply for a resource in advance for upcoming service data. In this case, the resource management device may continue to allocate uplink resources for transmitting the second BSR to the electronic device 100. The second BSR here may include, for example, the traffic flow information described in the foregoing, i.e., the example shown in fig. 2.

Fig. 6 is a signaling flow diagram illustrating requesting uplink resources and transmitting data by a user equipment according to an embodiment of the present disclosure. In fig. 6, the UE may be implemented by the electronic device 100. As shown in fig. 6, in step S601, when the traffic data has not yet reached the logical channel, the UE transmits scheduling request information to the resource management device. Next, in step S602, the resource management device allocates resources for transmitting the first buffer status report to the UE. Next, in step S603, the UE transmits a first buffer status report to the resource management device by using the resource allocated by the resource management device (for example, the example shown in fig. 4 or fig. 5). Next, in step S604, the resource management device allocates resources for transmitting the second buffer status report to the UE. Next, in step S605, the UE transmits a second buffer status report (e.g., the example shown in fig. 2) to the resource management device. Next, in step S606, the resource management device allocates resources for transmitting uplink data to the UE. Next, when the traffic data arrives at the logical channel, the UE transmits uplink data using the resource allocated by the resource management device. Here, although fig. 6 shows a case where the UE transmits uplink data to the resource management device, the UE may actually transmit uplink data to other devices.

As described above, according to the embodiments of the present disclosure, the UE may first send the first buffer status report to the resource management device, and then send the second buffer status report including the traffic flow information to the resource management device. Here, the first buffer status report is compatible with the buffer status report in the existing standard, so that the report of the periodic information can be realized with less change to the existing standard.

The above describes an embodiment in which the electronic device 100 previously applies for a resource for transmitting traffic data in the case of having a resource management device in a wireless communication network. An embodiment in which the electronic device 100 applies for a resource for transmitting traffic data in advance without a resource management device in a wireless communication network will be described below.

Consider the following scenario: in the communication scenario of V2X (vehicle and other device) mode 2 (mode 2), there is no resource allocation device, and the vehicles as the user devices coordinate resources themselves. For example, in the case that a vehicle as a user equipment needs to transmit service data, after the data arrives, the occupation of subsequent resources may be broadcasted on a specific time-frequency resource, and then the service data may be transmitted using the previously occupied resources within a predetermined time range. Such occupancy may include single occupancy or periodic occupancy.

In the existing scheme, since a vehicle as a user equipment can only select resources to be occupied and transmit service data within a predetermined time range, where the predetermined time range is determined according to constraints on time delay, the vehicle may not select appropriate resources under the condition that the time delay requirement is relatively high, that is, the predetermined time range is relatively small.

Fig. 7 is a diagram illustrating a case where the user equipment cannot select an appropriate resource to transmit data. As shown in fig. 7, at time t1, the traffic data that UE1 needs to transmit arrives at the logical channel, k represents a predetermined time range, i.e., UE1 must transmit the traffic data before time t1+ k. In the case where k is small, e.g., 1ms, the UE1 may not have time to select the appropriate resource. As shown in fig. 7, the time-frequency resource selected by the UE1 exceeds the time t1+ k, and thus the requirement of time delay cannot be met.

According to the embodiment of the present disclosure, the electronic device 100 may transmit occupation information of resources used for transmitting the service data before the service data arrives at the logical channel, where the occupation information may include time-domain and frequency-domain positions of the resources. Preferably, the electronic device 100 may broadcast such occupancy information. Alternatively, if the electronic device 100 wants to occupy the resource periodically, the occupation information may further include periodic information of the resource occupation, for example, the period of the resource occupation or the frequency of the resource occupation may be included. Further, after the traffic data arrives at the logical channel and within a predetermined time range, the electronic device 100 may transmit the traffic data using the resources included in the occupancy information.

Fig. 8 is a schematic diagram illustrating a user equipment broadcasting resources to be occupied in advance according to an embodiment of the present disclosure. In fig. 8, the UE1 may be implemented by the electronic device 100. As shown in fig. 8, time t1 is the time when the traffic data arrives at the logical channel. Before traffic data arrives on the logical channel, the UE1 sends occupancy signaling, which may include the location of the time-frequency resource selected by the UE 1. Then within time t1+ k (including time t1+ k), the UE1 transmits traffic data using the selected time-frequency resources.

As described above, according to the embodiment of the present disclosure, since the electronic device 100 can broadcast the resource occupation information before the service data reaches the logical channel, the resource can be occupied in advance, so as to ensure that the service data is transmitted within the predetermined time range, and the requirement of the time delay is met.

Therefore, according to the embodiments of the present disclosure, in a case that a resource management device is included in a wireless communication network, an electronic device that needs to transmit data may transmit periodic information of service data that it transmits to the resource management device in a case that there is no service data to be transmitted in a logical channel. Therefore, before the service data to be sent in the logical channel, the resource management device can allocate resources to the electronic device according to the periodic information of the service data sent by the electronic device, thereby reducing the time delay. Furthermore, according to the embodiments of the present disclosure, in a case that the resource management device is not included in the wireless communication network, the electronic device that needs to transmit data may broadcast the occupation information of the resource before the service data reaches the logical channel, so as to ensure that the service data is transmitted within a predetermined time range, and meet the requirement of the time delay.

Fig. 9 is a block diagram illustrating a structure of an electronic device 900 serving as a resource management device in a wireless communication system according to an embodiment of the present disclosure. Here, the electronic apparatus 900 is an electronic apparatus capable of performing a resource management function. For example, the electronic device 900 may be a network-side device that manages resources of user devices within its coverage area. For another example, the electronic device 900 may also be a user device that manages resources of other user devices. In this case, the electronic device 900 may be a cluster head device of a cluster composed of a plurality of user devices, and manage resources of other user devices within the cluster.

Here, various units of the electronic device 900 may be included in the processing circuit. The electronic device 900 may include one or more processing circuits. Further, the processing circuitry may include various discrete functional units to perform various different functions and/or operations. It should be noted that these functional units may be physical entities or logical entities, and that units called differently may be implemented by the same physical entity.

According to an embodiment of the present disclosure, the electronic device 900 may receive service traffic information of the user equipment from the user equipment through the communication unit 930, the service traffic information including periodicity information of service data transmitted by the user equipment.

According to an embodiment of the present disclosure, the allocating unit 920 may allocate resources for the user equipment according to the period determined by the determining unit 910.

According to an embodiment of the present disclosure, the electronic device 900 may implicitly indicate to the user device a periodicity of allocating resources for the user device.

Therefore, according to the electronic device 900 of the embodiment of the present disclosure, the period for allocating resources to the user equipment may be determined according to the period for sending the service data reported by the user equipment. Further, the electronic device 900 can indicate the period for allocating resources for the user device in an implicit manner. Therefore, the periodic information reported by the user equipment can support more types of periods, so that the period for allocating the resources is matched with the actual period of the service of the user equipment, the transmission delay of the periodic service can be reduced, and the utilization rate of the resources can be improved.

According to an embodiment of the present disclosure, as shown in fig. 9, the electronic device 900 may include a generating unit 940 for generating resource allocation information. Further, the electronic device 900 may transmit the resource allocation information to the user equipment through the communication unit 930. For example, the electronic device 900 may carry resource allocation information through DCI.

Here, in the case where the electronic device 900 receives traffic information from the user equipment and determines a period for allocating resources to the user equipment according to periodicity information included in the traffic information, the resource allocation information generated by the generation unit 940 may include frequency domain resources allocated to the user equipment for transmitting traffic data in each period and time domain resources allocated to the user equipment for first transmitting traffic data, without the electronic device 900 transmitting periodicity information for allocating resources to the user equipment.

In addition, in the case that the electronic device 900 does not receive the traffic information from the user equipment and determines the period for allocating the resource to the user equipment through observation statistics, the resource allocation information generated by the generation unit 940 may include the frequency domain resource allocated to the user equipment for transmitting the traffic data in each period and the time domain resource allocated to the user equipment for transmitting the traffic data for the first time. In addition, the electronic device 900 can utilize RRC signaling to carry periodic information that allocates resources for the user equipment.

According to an embodiment of the present disclosure, as shown in fig. 9, the electronic device 900 may further include an encoding unit 950 for encoding, e.g., scrambling, the resource allocation information generated by the generating unit 940.

In the SPS scheduling method, in the case where the RRC signaling includes periodic information, the encoding unit 950 may scramble the resource allocation information using an RNTI corresponding to the resource allocation information in the case where the RRC signaling includes periodic information in the SPS scheduling method.

According to an embodiment of the present disclosure, the electronic device 900 may also receive scheduling request information from the user equipment through the communication unit 930. Further, the allocating unit 920 may allocate resources for transmitting the traffic flow information to the user equipment in response to the scheduling request information.

According to an embodiment of the present disclosure, the traffic information may be carried through the MAC CE. Specifically, the traffic flow information may be included in the BSR in the MAC CE.

According to an embodiment of the present disclosure, the periodicity information may include a period of the traffic data transmitted by the user equipment or a frequency of the traffic data transmitted by the user equipment. The determining unit 910 may determine a period of the service data transmitted by the user equipment or a frequency of the service data transmitted by the user equipment according to periodicity information included in the service traffic information. Further, in case that the periodicity information includes a frequency of the traffic data transmitted by the user equipment, the determining unit 910 may determine the period according to the frequency, for example, according to an inverse of the frequency.

According to an embodiment of the present disclosure, the traffic flow information may further include at least one of: indication information indicating whether the periodicity information is periodic or frequency, size information of the service data buffered by the user equipment, and arrival time information of the service data expected by the user equipment. The determining unit 910 may determine a period of the traffic data transmitted by the user equipment according to the indication information and the periodicity information, and the allocating unit 920 may allocate resources for the user equipment according to time of arrival information of the traffic data expected by the user equipment.

According to an embodiment of the present disclosure, in a case that the electronic device 900 receives the first BSR as shown in fig. 4 or fig. 5, the electronic device 900 may further allocate uplink resources for transmitting a second BSR for the user equipment, and acquire the traffic flow information through the second BSR.

According to the embodiment of the present disclosure, the allocating unit 920 may determine the time domain resource for the user equipment to transmit the service data in each period according to the time domain resource for the user equipment to transmit the service data for the first time and the period for the electronic device 900 to allocate the resource to the user equipment.

According to an embodiment of the present disclosure, in a case that a period of allocating resources is not an integer multiple of a minimum unit in which the electronic device 900 allocates time domain resources, the allocating unit 920 may adjust the time domain resources in which the user equipment transmits traffic data in each period to an integer multiple of the minimum unit.

According to an embodiment of the present disclosure, the allocating unit 920 may determine the time when the user equipment transmits the traffic data in each period according to the time domain resource in which the user equipment transmits the traffic data for the first time and the period in which the resource is allocated, and adjust the time to an integer multiple of the minimum unit by rounding up the time.

According to the embodiment of the present disclosure, the allocating unit 920 may also adjust the period to be an integer multiple of the minimum unit by rounding up the period of the allocated resources, and determine the time domain resource for the user equipment to transmit the traffic data in each period according to the time domain resource for the user equipment to transmit the traffic data for the first time and the adjusted period.

Here, a manner in which the allocating unit 920 determines, according to the time domain resource in which the user equipment first transmits the service data and the period in which the electronic device 900 allocates the resource to the user equipment, the time domain resource in which the user equipment transmits the service data in each period may be similar to the manner determined by the determining unit 130 in the electronic device 100, and is not described herein again. That is, the electronic device 900 should agree with the user equipment in a manner of determining resources for transmitting the traffic data at each period, and determine the resources allocated to the user equipment in a manner consistent with the user equipment.

As described above, according to the embodiment of the present disclosure, the electronic device 900 may indicate the period for allocating resources to the ue in an implicit manner, so as to support more kinds of periods, and enable the period for allocating resources to be matched with the actual period of the service of the ue, thereby reducing the transmission delay of the periodic service and improving the utilization rate of the resources.

The eNB 1200 includes one or more antennas 1210 and a base station apparatus 1220. The base station apparatus 1220 and each antenna 1210 may be connected to each other via an RF cable.

Each of the antennas 1210 includes a single or multiple antenna elements (such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna), and is used for the base station apparatus 1220 to transmit and receive wireless signals. As shown in fig. 12, eNB 1200 may include multiple antennas 1210. For example, the multiple antennas 1210 may be compatible with multiple frequency bands used by the eNB 1200.
