Description

Resource processing method, device and system, and resource receiving method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for processing a resource, and a method and an apparatus for receiving a resource.

Background

In the NB-IoT Rel-15 standard protocol, if the terminal does not have downlink scheduling, the terminal can report the uplink data transmission requirement through a dedicated uplink Scheduling Request (SR) resource, and the dedicated SR resource is a non-competitive PRACH resource. And the terminal sends a random access signal in the configured special SR non-contention PRACH to indicate that uplink data needs to be transmitted. The assignment of dedicated PRACH on NB-IoT Rel-15 standard is exclusive to the assigned PRACH at all times during the terminal's access to the system. The time allocation density of the PRACH is generally higher than the reporting granularity of uplink data transmission that the terminal needs to indicate through the SR, so this method may cause a low utilization rate of dedicated SR resources. In order to support more users to configure dedicated SR resources, the system needs to configure many PRACH resources, which results in a large system overhead and even fails to meet the requirements of dedicated SR resources.

Example 1

The method provided by the first embodiment of the present application may be executed in a mobile terminal, a computer terminal, or a similar computing device. Taking the example of being operated on a mobile terminal, fig. 1 is a hardware structure block diagram of the mobile terminal of a resource processing method according to an embodiment of the present invention. As shown in fig. 1, the mobile terminal 10 may include one or more (only one shown in fig. 1) processors 102 (the processor 102 may include, but is not limited to, a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, and optionally may also include a transmission device 106 for communication functions and an input-output device 108.

For example, the mobile terminal 10 may also include more or fewer components than shown in FIG. 1, or have a different configuration than shown in FIG. 1.

The memory 104 may be used to store computer programs, for example, software programs and modules of application software, such as computer programs corresponding to the resource processing method in the embodiment of the present invention, and the processor 102 executes various functional applications and data processing by running the computer programs stored in the memory 104, so as to implement the above-mentioned method.

In one example, the transmission device 106 may be a Radio Frequency (RF) module, which is used for communicating with the internet in a wireless manner.

In this embodiment, a method for processing resources running on the mobile terminal is provided, and fig. 2 is a flowchart of a method for processing resources according to an embodiment of the present invention, as shown in fig. 2, the flowchart includes the following steps:

step S202, configuring an uplink Scheduling Request (SR) resource for User Equipment (UE), wherein the SR resource is used for the UE to send an SR;

step S204, sending a first message to the UE, where the first message carries configuration information of the SR resource, and the configuration information at least includes: time domain location information and frequency domain location information.

Optionally, the resource comprises: the SR dedicated PRACH resource.

Specifically, the present embodiment is mainly applied to SR resources of non-contention PRACH resources. It should be noted that, for convenience of illustration, the contents described in the following embodiments all depend on a scenario in which PRACH resources are used as SR resources. Of course, other resource types capable of serving as SR resources are also within the scope of the present embodiment. And will not be described herein in more detail.

Specifically, the coverage level of the SR resource refers to a coverage level of a cell in which the UE is located.

Specifically, the carrier index of the SR resource and the subcarrier index of the SR resource are used to indicate the position of the carrier and the subcarrier acquired by the UE. For example, if the value in the carrier index of the SR resource is 0 and the value in the subcarrier index of the SR resource is 2, it indicates that the UE acquires the 2 nd subcarrier of the carrier 0. Accordingly, the UE can determine location information of resources on the frequency domain.

Specifically, the resource information of the SR resource is used to indicate location information of a frequency domain and a time domain for each coverage level. For example, the resource information of the SR resource corresponds to a coverage level 0, a time domain period is 40s, a start time is 8ms, and corresponding subcarriers are 0 to 11. Therefore, when the period and the starting time of the SR resource are calculated subsequently, the calculation can be performed based on the resource information.

In addition, since the resource information of the SR resource is common information, it is not specific information transmitted for a specific UE. Meanwhile, the mode of broadcasting the message by the broadcasting system cannot ensure that each UE can successfully receive the resource information of the SR resource at one time. Therefore, in order to prevent some UEs from failing to receive the resource information of the SR resource, on one hand, it is ensured that each UE can receive the resource information of the SR resource by the base station periodically transmitting the resource information of the SR resource for multiple times. On the other hand, in order to save resources, the UE may transmit a response to the base station, after receiving the resource information of the SR resource. If the base station does not receive the response of the UE within the predetermined time threshold, the base station sends the response again to the non-responding UE through separate information.

Specifically, the time domain configuration index table of the SR resource refers to time domain periods of different SR resources corresponding to time domain offset indexes of the different SR resources. For example, when the time domain offset index of the SR resource is 0, the time domain period of the SR resource is 40ms, and when the time domain offset index of the SR resource is 1, the time domain period of the SR resource is 80 ms. After receiving the time domain configuration index table, the subsequent UE can determine the time domain period of the corresponding SR resource according to the value of the time domain offset index of the SR resource.

Specifically, the period factor of the SR resource is a multiple of the time domain period of the SR with respect to the time domain period corresponding to the coverage level. In addition, for convenience of management, the period factor of the SR resource takes an integer of 2 to 64.

Specifically, the resource information of the SR resource is also used to indicate location information of a frequency domain, a time domain, and a repetition number for each coverage level. For example, the resource information of the SR resource corresponds to a coverage level 0, a time domain period is 40s, a start time is 8ms, corresponding subcarriers are 0 to 11, and the number of repetitions is 2. Therefore, in the subsequent calculation, the calculation can be performed based on the resource information.

Specifically, although multiple resources of a coverage level may be repeatedly time division multiplexed to multiple users, each UE uses only a portion of the resource repetition of the coverage level. Specifically, the number of repetitions of the SR resource coefficient includes at least: 1,1/2,1/4,1/8,1/16,1/32,1/64,1/128. The time domain repetition offset of the SR resource is an nth repetition of the resource repetition corresponding to the coverage level, and is used to determine the repetition part actually used by the user. The time domain repetition offset is an integer from 0 to 128. For example, if the value of the time domain repetition offset is 5, it means that the 5 th repetition in the resource repetition corresponding to the coverage level is used to determine the repetition part actually used by the user.

Specifically, the second information includes at least a preamble code.

It should be noted that the frequency domain positions of the SR resources allocated by the base station to the UE may be the same carrier and subcarrier, or may be different carriers and subcarriers. Therefore, through the configuration information, the base station can configure multiple user time domains for the UE on SR resources at the same or different frequency domain positions. Therefore, the utilization efficiency of the special SR PRACH resource can be improved, the requirements of more terminal SR PRACH resources are met, and the system overhead is reduced.

Through the steps, the problems that the utilization efficiency of SR resources is low and the resource requirements of a system cannot be met in the related technology are solved, and the effects of improving the service efficiency of the SR resources, meeting the requirements of more user side equipment on the SR resources and reducing the system overhead are achieved.

Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.

Example 2

In this embodiment, a method for processing resources running on the mobile terminal is provided, and fig. 3 is a flowchart of a method for receiving resources according to an embodiment of the present invention, which has been described and is not described again. As shown in fig. 3, the process includes the following steps:

step S302, after accessing a network side device, a user side device receives a resource configured by the network side device and used for performing an uplink scheduling request SR; wherein, the configuration mode comprises: configuring a time domain position of the resource;

step S304, according to the configuration information, the UE determines the position of the SR resource for triggering SR in uplink data transmission.

In addition, since the resource information of the SR resource is common information, it is not specific information transmitted for a specific UE. Meanwhile, the mode of broadcasting the message by the broadcasting system cannot ensure that each UE can successfully receive the resource information of the SR resource at one time. Therefore, in order to prevent some UEs from failing to receive the resource information of the SR resource, on one hand, it is ensured that each UE can receive the resource information of the SR resource by the base station periodically transmitting the resource information of the SR resource for multiple times. On the other hand, in order to save resources, the UE may transmit a response to the base station, after receiving the resource information of the SR resource. And if the base station does not receive the response of the UE within the preset time threshold, the base station sends the response to the non-responded UE again through separate information.

Specifically, the time domain offset index of the SR resource includes a plurality of different time domain offset values corresponding to different coverage levels. If the time domain offset value of the SR resource required by the current UE needs to be determined, the time domain offset value needs to be obtained by multiplying the time domain period corresponding to the coverage level by the index value corresponding to the time domain period corresponding to the coverage level in the time domain offset index of the SR resource. For example, if the time domain period corresponding to the coverage level of level 0 is 40ms and the time domain offset index of the SR resource corresponding thereto takes a value of 10, the time domain offset value of the SR resource is 400 ms. In addition, for convenience of management, the period factor of the SR resource is an integer from 0 to 64.

Specifically, the period factor of the SR resource is a multiple of the time domain period of the SR with respect to the time domain period corresponding to the coverage level. For example, if the coverage level of level 0 corresponds to a time domain period of 40ms and the period factor of the SR resource is 5, then the time domain period of the SR resource can be calculated to be 200 ms. In addition, for convenience of management, the period factor of the SR resource takes an integer of 2 to 64.

Specifically, the time domain repetition number of the SR resource can be calculated by a multiplication result of the resource repetition number of the coverage level and the repetition number coefficient of the SR resource, for example, if the resource repetition number of the coverage level 0 is 160 and the repetition number coefficient of the SR resource is 1/32, the time domain repetition number of the SR resource is 5.

Specifically, the time domain repetition part of the SR resource may also be determined according to the time domain repetition offset of the SR resource and the time domain repetition number of the SR resource, for example, if the time domain repetition offset is 1, the results are 1 and 5. From this result, the 1 st repetition and the 5 th repetition of the coverage level 0 repetition were used.

Optionally, the method further comprises: and the UE sends second information to the base station on the determined SR resource, wherein the second information is used for indicating the data transmission requirement.

Specifically, the second information includes at least a preamble code.

Optionally, the method further comprises: and the time domain positions of SR resources configured for different UEs by the base station are different.

It should be noted that, according to the above embodiment, the following scenarios are also provided to facilitate understanding of the technical solutions:

scene 1:

1. the base station configures cell PRACH resources in SIB2, where an indicated PRACH resource information table is shown in table 1:

TABLE 1

Coverage grade	PRACH period (ms)	PRACH start time (ms)	Subcarrier of PRACH
				0	40	8	0～11
1	80	64	12～23
				2	640	256	24～35

After the UE1 accesses, the base station issues dedicated SR PRACH configuration information as shown in table 2:

TABLE 2

After the UE2 accesses, the base station issues dedicated SR PRACH configuration information as shown in table 3:

TABLE 3

After the UE3 accesses, the base station issues dedicated SR PRACH configuration information as shown in table 4:

TABLE 4

5. As can be seen from tables 1 and 2, the UE1 acquires the 2 nd subcarrier with the frequency domain configuration as carrier 0.

The time domain period of the PRACH resource of the SR corresponding to the UE is the PRACH period of coverage level 0, 40ms multiplied by the PRACH period factor 2 and equal to 80 ms.

Since the PRACH time domain offset index is 0, the time domain offset value corresponding to the PRACH resource of the SR of the UE1 is also 0, and therefore the starting time of the PRACH resource of the SR is 8 ms.

The UE1 sends a preamble on the configured time-frequency domain SR PRACH resource (the 2 nd subcarrier of the carrier 0, the time domain cycle of the PRACH resource is 80ms, and the start time is 8ms), indicating the data transmission requirement.

6. As can be seen from tables 1 and 3, the UE2 also acquires the 2 nd subcarrier with the frequency domain configuration as carrier 0.

Meanwhile, the time domain period of the PRACH resource of the SR corresponding to the UE2 is the PRACH period of coverage level 0, 40ms multiplied by the PRACH period factor 2 and equal to 80 ms.

However, since the PRACH time domain offset index is 1, the time domain offset value corresponding to the PRACH resource of the SR of the UE2 is different from the time domain offset value corresponding to the PRACH resource of the SR of the UE1, that is, 40ms, and the starting time of the PRACH resource of the final SR is 48 ms.

The UE2 sends a preamble on the configured time-frequency domain SR PRACH resource (the 2 nd subcarrier of the carrier 0, the time domain cycle of the PRACH resource is 80ms, and the start time is 48ms), indicating the data transmission requirement.

7. As can be seen from tables 1 and 4, the UE1 acquires the 2 nd subcarrier with the frequency domain configuration as carrier 0.

However, since the PRACH period factor is 1, the time domain period of the PRACH resource of the SR corresponding to the UE3 is 40ms multiplied by 1 to be equal to 40 ms.

The UE1 sends a preamble on the configured time-frequency domain SR PRACH resource (2 nd subcarrier of carrier 0, time domain cycle of PRACH resource is 40ms, start time is 8ms), indicating a data transmission requirement.

Therefore, it can be seen that the base station can configure the same frequency domain (i.e., the 2 nd subcarrier of the carrier 0), and can ensure different configurations in the time domain by adjusting the PRACH period factor and the PRACH time domain offset index, so that the dedicated SR PRACH resource at the same frequency domain position can be configured for time domain orthogonal multiplexing of multiple users, thereby improving the utilization efficiency of the dedicated SRPRACH resource, satisfying the demands of SR PRACH resources of more terminals, and reducing the system overhead.

Scene 2:

1. the base station configures cell PRACH resources in SIB2, where the indicated PRACH resource information still follows the PRACH resource information table in table 1 for convenience of example. Of course, other PRACH resource information tables are also within the protection scope of the present scenario, and are not described herein in detail.

2. The base station defines a time domain configuration index table of SR PRACH resources, as shown in table 5.

TABLE 5

Index value Isr	Time domain period of PRACH resource	PRACH TIME-Domain OFFSET INDEX
			0	40	Isr
1～2	80	Isr-1
			3～6	160	Isr-3
7～12	240	Isr-7
			13～20	320	Isr-13
21～36	640	Isr-21
			37～68	1280	Isr-37
69～132	2560	Isr-69

After the UE1 accesses, the base station issues dedicated SR PRACH configuration information as shown in table 6:

TABLE 6

After the UE2 accesses, the base station issues dedicated SR PRACH configuration information as shown in table 7:

TABLE 7

4. As can be seen from table 1, table 5 and table 6, the UE1 acquires the 2 nd subcarrier with the frequency domain configuration as carrier 0.

The time domain cycle of the PRACH resource of the SR corresponding to the UE1 is known from the look-up table 6, and the time domain cycle of the PRACH resource corresponding to the time domain offset index 1 is 80 ms.

Since the PRACH time domain offset index is 1, the time domain offset value corresponding to the PRACH resource of the SR of the UE1 is 40ms, and therefore the starting time of the PRACH resource of the SR is 48 ms.

5. As can be seen from table 1, table 5 and table 7, the UE1 acquires the 2 nd subcarrier with the frequency domain configuration as carrier 0.

The time domain period of the PRACH resource of the SR corresponding to the UE1 is known from the look-up table 6, and the time domain period of the PRACH resource corresponding to the time domain offset so 3 is 160 ms.

Since the PRACH time domain offset index is 3, the time domain offset value corresponding to the PRACH resource of the SR of the UE1 is also 120ms, and therefore the starting time of the PRACH resource of the SR is 128 ms.

The UE1 sends a preamble on the configured time-frequency domain SR PRACH resource (2 nd subcarrier of carrier 0, time domain period of PRACH resource is 160ms, start time is 128ms), indicating a data transmission requirement.

Therefore, it can be seen that the base station can configure the same frequency domain (i.e., the 2 nd subcarrier of the carrier 0) and can ensure different configurations in the time domain by adjusting the PRACH time domain offset index, so that the dedicated SR PRACH resource in the same frequency domain position can be configured for time domain orthogonal multiplexing of multiple users, thereby improving the utilization efficiency of the dedicated SR PRACH resource, satisfying the demands of SR PRACH resources of more terminals, and reducing the system overhead.

Scene 3:

1. the base station configures the PRACH resource of the cell in the SIB2, where the indicated PRACH resource information table is as shown in table 8: .

TABLE 8

After the UE1 accesses, the base station issues dedicated SR PRACH configuration information as shown in table 9:

TABLE 9

After the UE2 accesses, the base station issues dedicated SR PRACH configuration information as shown in table 10:

watch 10

After the UE3 accesses, the base station issues dedicated SR PRACH configuration information as shown in table 11:

TABLE 11

5. As can be seen from tables 1 and 9, the UE1 acquires the 2 nd subcarrier with the frequency domain configuration as carrier 0.

The time domain repetition number of the user SR PRACH resource corresponding to the UE1 is the PRACH repetition number 4 corresponding to the coverage level 1 multiplied by the SR PRACH repetition number coefficient 1/2 equal to 2.

While the SR PRACH resource time domain repetition part is 0 and 1, using the 0 th and 1 st repetition in the coverage level 1 repetition.

The UE1 sends a preamble on the configured time-frequency domain SR PRACH resource (the 2 nd subcarrier of carrier 0, the SR PRACH resource time domain repetition number is 2, and the 0 th and 1 st repetitions in the coverage level 1 repetition) to indicate the data transmission requirement.

6. As can be seen from tables 1 and 10, the UE2 acquires the 2 nd subcarrier with the frequency domain configuration as carrier 0.

The time domain repetition times of the user SR PRACH resource corresponding to the UE2 are the same as those of the UE1, i.e. 2.

However, since the SR PRACH time domain repetition offsets are different, the SR PRACH resource time domain repetition portions of the UE2 are 1 and 2, using the 1 st and 2 nd repetitions in the coverage level 1 repetition.

The UE1 sends a preamble on the configured time-frequency domain SR PRACH resource (2 nd subcarrier of carrier 0, SR PRACH resource time domain repetition number is 2,1 st and 2 nd repetition in coverage level 1 repetition) to indicate a data transmission requirement.

7. As can be seen from tables 1 and 11, the UE3 acquires the 2 nd subcarrier with the frequency domain configuration as carrier 0.

However, the time domain repetition number of the user SR PRACH resource corresponding to the UE3 is different from that of the UE1, and the time domain repetition number of the user SR PRACH resource corresponding to the UE1 is equal to the PRACH repetition number 4 corresponding to the coverage level 1 multiplied by the SR PRACH repetition number coefficient 1/4.

Therefore, the time domain repetition part of the user SR PRACH resource corresponding to the UE3 is also different from that of the UE1, i.e. 0, i.e. the 0 th repetition of the coverage level 1 repetition is used.

The UE1 sends a preamble on the configured time-frequency domain SR PRACH resource (the 2 nd subcarrier of carrier 0, the SR PRACH resource time domain repetition number is 1, the 0 th repetition in the coverage level 1 repetition) to indicate the data transmission requirement.

Therefore, it can be seen that the base station can configure the same frequency domain (i.e., the 2 nd subcarrier of the carrier 0), and can ensure different configurations in the time domain by adjusting the SR PRACH repetition number coefficient and the SR PRACH time domain repetition offset, so that the dedicated SR PRACH resources in the same frequency domain position can be configured for time domain orthogonal multiplexing of multiple users, thereby improving the utilization efficiency of the dedicated SR PRACH resources, satisfying the demands of more terminal SR PRACH resources, and reducing the system overhead.

It should be noted that the distances of the above scenarios are only an example, and are not exhaustive, and any examples based on the above scenarios of the present invention are within the protection scope of the present embodiment. E.g., different frequency domain configuration information.
