And reporting the current BSR to the base station; the base station allocates an uplink resource for transmitting the uplink data to the UE according to the received BSR; and after receiving the uplink resource allocated by the base station, the UE transmits the uplink data that needs to be transmitted to the base station to the uplink resource. Sent to the base station. In the above manner, the UE needs to send the request to the base station twice to obtain the uplink resource for sending the uplink data, thereby reducing the efficiency of acquiring the uplink resource. Therefore, the present disclosure provides an uplink resource acquisition method, which enables the SR to carry a cache identifier for indicating the buffer size of the uplink data when the UE sends the SR, so that the UE obtains sufficient transmission from the base station at one time. Uplink resources of uplink data to improve the accuracy and efficiency of the UE to obtain uplink data.

Finally, the system architecture involved in the embodiments of the present disclosure is introduced.

Referring to FIG. 1, the system includes a base station and a UE within the coverage of the base station, and the base station can communicate with the UE. A plurality of UEs may be included in the coverage of one base station. For convenience of description, a base station and a UE are taken as an example in FIG. 1 of the embodiment of the present disclosure. The eNB may send an RRC message to the UE, and after processing the RRC message, process the N cache thresholds included in the SR configuration carried in the RRC message. The UE may receive the RRC message, and when the SR needs to be sent, according to the N cache thresholds carried in the SR configuration, the SR carries a cache identifier for indicating the buffer size of the uplink data, so that the base station receives the SR. The uplink resource that is sufficient to send uplink data may be allocated to the UE according to the cache identifier. The UE may send the uplink data after receiving the uplink resource.

In the embodiment of the present disclosure, when there is uplink data to be transmitted in the target logical channel of the UE, and there is no uplink resource for transmitting the uplink data, the UE may carry the indication in the sent SR in order to obtain an accurate uplink resource.

All of the above optional technical solutions may form an optional embodiment of the present disclosure in any combination, and the embodiments of the present disclosure will not be further described herein.

FIG. 3 is a flowchart of an uplink resource acquisition method according to an exemplary embodiment. As shown in FIG. 3, the method is used in a base station, and includes the following steps.

In step 301, the uplink scheduling request SR sent by the user equipment UE is received, where the SR carries a cache identifier, where the cache identifier is an identifier corresponding to the buffer size of the uplink data to be transmitted existing in the target logical channel of the UE.

In step 302, based on the cache identifier, the UE is allocated an uplink resource for transmitting the uplink data.

In the embodiment of the present disclosure, the base station may receive the SR sent by the UE, and the base station can allocate the uplink resource that is sufficient to send the uplink data to the UE at one time according to the cache identifier. The accuracy and efficiency of the UE acquiring uplink resources are improved.

Optionally, the uplink resource that is used to transmit the uplink data is allocated to the UE, including:

And determining, from the stored N+1 buffer intervals corresponding to the target logical channel, a buffer interval that is the same as the cache identifier, where the N+1 cache intervals respectively correspond to an interval identifier;

The UE is allocated the maximum uplink resource indicated by the determined buffer interval.

Transmitting, to the UE, a radio resource control protocol RRC message, where the RRC message carries an SR configuration of each of the plurality of logical channels, where the SR configuration includes N cache thresholds, where N is a positive integer greater than or equal to 1;

Optionally, the uplink resource allocated for transmitting the uplink data is allocated to the UE according to the cache identifier, including:

Determining, according to the cache identifier, a cache threshold corresponding to the cache identifier from the N cache thresholds included in the stored SR configuration of the target logical channel;

Optionally, N cache thresholds are used to indicate that the UE does not trigger the buffer status report BSR.

Since the UE needs to transmit by using the resource (SR configuration) for transmitting the SR when transmitting the SR, the SR configuration is sent to the UE when the RRC message is sent by the base station, and after the eNB sends the RRC message, the base station also configures the SR. N cache thresholds are processed. The operation of transmitting an RRC message to the base station and processing the N cache thresholds is described below with reference to FIG. 4, which specifically includes the following steps.

In step 401, the base station sends an RRC message to the UE, where the RRC message carries the SR configuration of each of the plurality of logical channels, and the SR configuration includes N cache thresholds, where N is a positive integer greater than or equal to 1.

The RRC message may be sent to the UE when the base station detects that the UE accesses, or may be sent to the UE when the base station determines that there is no resource for transmitting the SR in the UE.

It should be noted that the SR configuration may include not only N cache thresholds, but also the time-frequency resources, periods, SR suppression timers, and the like.

It is to be noted that the RRC message sent by the base station may carry the SR configuration of each of the plurality of logical channels, that is, the RRC message may carry multiple SR configurations, and the multiple SR configurations and multiple The logical channels correspond one-to-one. In an actual application, the multiple SR configurations carried in the RRC message may not be in one-to-one correspondence with multiple logical channels in the UE, but each of the multiple SR configurations may correspond to multiple logical channels. For example, if the UE includes 10 logical channels, the RRC message sent by the base station may include 10 SR configurations, and the 10 SR configurations are respectively in one-to-one correspondence with the 10 logical channels. In addition, if 10 logical channels can be divided into 5 logical channels For a group, each logical channel group includes two logical channels, and the RRC message sent by the base station may also include only five SR configurations. For each of the five SR configurations, the SR configuration may correspond to two logical channels in one logical channel group.

In step 402, for each logical channel of the plurality of logical channels, the base station determines N+1 buffer intervals based on the N cache thresholds included in the SR configuration of the logical channel, and the N+1 buffer intervals do not overlap each other.

The base station may sort the N cache thresholds in ascending order, and any one of the N cache thresholds may form a left-to-right closed buffer interval with the adjacent cache threshold. The minimum cache threshold has only one cache threshold adjacent thereto. Therefore, the minimum cache threshold may be a cache interval that is greater than the minimum cache threshold and adjacent to the minimum cache threshold. At the same time, it can also form a buffer interval with left and right closed with 0. Similarly, the maximum cache threshold also has only one cache threshold adjacent thereto. Therefore, the maximum cache threshold may be a left open right closed with a cache threshold that is less than the maximum cache threshold and adjacent to the maximum cache threshold. Cache interval. At the same time, it is also possible to form a left-to-right closed buffer interval with any value greater than the maximum buffer threshold.

It is to be noted that, in order to enable the base station to directly allocate uplink resources sufficient for transmitting uplink data to the UE according to the buffer size of the uplink data, in general, the value greater than the maximum buffer threshold should be as large as possible, for example, the value may be It is 2 times larger than the cache threshold and so on.

For example, when the SR configuration includes three buffer thresholds, and the three buffer thresholds are A1, A2, and A3, respectively, the four buffer intervals determined by the three buffer thresholds may be (0, A1], (A1, A2). ], (A2, A3) and (A3, 2*A3).

It should be noted that, since the base station can not only sort the N cache thresholds in descending order, but also sort them in other orders, for example, from large to small, when the base station follows the N cache thresholds. After sorting in the order of large to small, any one of the N cache thresholds and the adjacent cache threshold may be configured as a left-to-right closed buffer interval.

In step 403, the base station allocates an interval identifier for each of the N+1 buffer intervals according to the first preset policy.

The first preset policy may be set in advance. For example, the first preset policy may be sequentially allocated to N+1 buffer intervals according to the Arabic numerals from small to large, and may also be forward-to-back according to the English alphabet. The sequence is sequentially assigned to N+1 buffer intervals. Of course, in actual applications, N+1 buffer intervals may be sequentially assigned to other sequences.

It should be noted that the interval identifier is used to uniquely identify the buffer interval, and the interval identifier may be a letter, a number, or the like according to a first preset policy. For example, when the first preset policy is sequentially allocated to N+1 buffer intervals in the order of the Arabic numerals from small to large, the interval identifier may be a number, and when the first preset policy is in accordance with the English alphabet from front to back. The order is sequentially assigned to N+1 buffer intervals, and the interval identifier can be a letter.

For example, when the buffer interval is (0, A1], (A1, A2], (A2, A3], and (A3, 2*A3), the first preset strategy is to sequentially allocate the Arabic numerals in ascending order. When N+1 buffer intervals are given, the cache identifier assigned to the buffer interval (0, A1) is 0, the cache identifier assigned to (A1, A2) is 1, and the cache identifier assigned to (A2, A3) is 2. The cache identifier assigned to (A3, 2*A3) is 3.

In the embodiment of the present disclosure, after transmitting the RRC message to the UE, the base station may process the N cache thresholds in the SR configuration, so as to ensure that the uplink resources that are sufficient to send uplink data are allocated to the UE, and the uplink resources are allocated. Accuracy and efficiency.

In the embodiment of the present disclosure, after the eNB sends the RRC message to the UE, the operation of processing the SR configuration included in the RRC message may include the foregoing manner, and may include other manners. The operation of processing the N cache thresholds included in the SR configuration is described, and specifically includes the following steps.

In step 501, the base station sends an RRC message to the UE.

For the related operations of the eNB transmitting the RRC to the UE, reference may be made to the foregoing step 401, which is not repeatedly described in the embodiment of the present disclosure.

In step 502, for each of the plurality of logical channels, the base station allocates a cache identifier to each of the N cache thresholds included in the SR configuration of the logical channel according to the second preset policy.

The second preset policy may be set in advance. For example, the second preset policy may be sequentially assigned to N cache thresholds according to the order of the Arabic numerals from small to large, or may be in order from the front to the back of the alphabet. Assigned to N cache thresholds, of course, in actual applications, N cache thresholds may be assigned to other sequences in turn.

It should be noted that the cache identifier is used to uniquely identify the cache threshold, and the cache identifier may be a letter, a number, or the like according to a second preset policy. For example, when the second preset policy is sequentially assigned to N cache thresholds in the order of the Arabic numerals from small to large, the cache identifier may be a number, and the second preset policy is in order from the front to the back of the alphabet. Assigned to N cache thresholds Value, the cache identifier can be a letter.

For example, when the cache thresholds A1, A2, and A3 are sequentially assigned to N cache thresholds in descending order of Arabic numerals, the cache identifier assigned to the cache threshold A1 is 0, which is a cache. The cache ID assigned to threshold A2 is 1 and the cache identifier assigned to cache threshold A3 is 2.

After the base station sends the RRC message to the UE, when there is an uplink data to be sent in the UE and there is no uplink resource for transmitting the uplink data, the base station may send the SR to the base station according to the N buffer thresholds included in the SR configuration carried in the RRC message. In order to obtain an uplink resource sufficient to send uplink data. The operation of obtaining the uplink resource acquisition by the UE from the base station is described in detail below with reference to FIG. 6, which specifically includes the following steps.

In step 601, when there is uplink data to be transmitted in the target logical channel, and there is no uplink resource for transmitting the uplink data, the UE determines a cache identifier corresponding to the buffer size of the uplink data.

It can be seen from the foregoing FIG. 4 and FIG. 5 that after the eNB sends the RRC message to the UE, the processing of the N cache thresholds includes two modes. Therefore, the operation of determining the cache identifier corresponding to the buffer size of the uplink data by the UE may also include the following. Said two ways.

In the first mode, the UE determines the buffer interval of the buffer size of the uplink data from the N+1 buffer intervals corresponding to the stored target logical channel, and determines the interval identifier corresponding to the determined buffer interval as the buffer size of the uplink data. Corresponding cache identifier.

The UE may compare the buffer size of the uplink data with the N+1 buffer intervals corresponding to the stored target logical channel, and when there is a buffer interval including the cache size of the uplink data in the N+1 buffer intervals, The buffer interval is determined as a buffer interval in which the buffer size of the uplink data is located.

Further, as shown in FIG. 4 above, after the eNB sends the RRC message to the UE, the base station may process the N buffer thresholds, so that the subsequent UE can obtain the uplink resource that is sufficient to send the uplink data from the base station. After receiving the RRC message sent by the base station, the UE may further determine, according to the N cache thresholds included in the SR configuration of the logical channel, N+1 buffer intervals for each of the plurality of logical channels, the N+1 Cache intervals do not overlap each other; A preset strategy assigns an interval identifier to the N+1 buffer intervals.

The operation of the UE to determine the N+1 buffer intervals based on the N cache thresholds and assigning an interval identifier to the N+1 buffer intervals according to the first preset policy may refer to the foregoing steps in the foregoing

steps

402 and 403. The buffer threshold determines N+1 buffer intervals, and an operation of assigning an interval identifier to the N+1 buffer intervals according to the first preset policy is not described in detail in the embodiment of the present disclosure.

It is to be noted that, when the UE determines the cache identifier corresponding to the buffer size of the uplink data in the foregoing manner, the buffer size of the uplink data is located in the buffer interval, so that the UE can obtain sufficient uplink data to be sent from the base station in one time. The uplink resources improve the reliability and efficiency of the UE acquiring uplink resources.

It should be noted that the target logical channel is any one of the multiple logical channels.

Further, when there is no uplink resource for transmitting the uplink data in the logical channel, the UE may determine whether to allocate an SR configuration for the target logical channel, and determine the target logic when the SR logical configuration is not allocated to the target logical channel. The logical channel group in which the channel is located, obtains the SR configuration allocated to the other logical channel from the logical channel group, and determines the acquired SR configuration as the SR configuration of the target logical channel.

It should be noted that, when the UE divides multiple logical channels into multiple logical channel groups, each logical channel group may be assigned a group identifier for uniquely identifying the logical channel group, and each The logical channel group and the group identifier are stored in a corresponding relationship. Therefore, when the UE needs to determine the logical channel group in which the target logical channel is located, the group identifier included in the target logical channel may be acquired first, and then according to the group identifier, the correspondence between the logical channel group and the group identifier is Obtaining a logical channel group corresponding to the group identifier, and determining the obtained logical channel group as a logical channel group in which the target logical channel is located.

In the second mode, the UE acquires N cache thresholds included in the SR configuration of the target logical channel, and determines, from the N cache thresholds, a minimum difference between the cache size of the uplink data and a cache larger than the uplink data. The cache threshold of the size is determined by using the cache identifier corresponding to the determined cache threshold as the cache identifier corresponding to the cache size of the uplink data.

The UE may compare the cache size of the uplink data with the N cache thresholds, determine a cache threshold that is greater than the cache size of the uplink data, and calculate a cache threshold between the determined cache threshold and the cache threshold of the uplink data. The difference is determined to determine the minimum cache threshold.

Further, as shown in FIG. 5 above, after the eNB sends an RRC message to the UE, the base station may process the N cache thresholds, so as to ensure that the subsequent UE can obtain the foot from the base station at one time. An uplink resource that can send uplink data. After receiving the RRC message sent by the base station, the UE may store an SR configuration of each of the multiple logical channels, and for each logical channel of the multiple logical channels, according to the second preset policy, the logic The N cache thresholds included in the SR configuration of the channel are respectively assigned a cache identifier.

The operation of the UE to allocate a cache identifier to the N cache thresholds of the SR configuration of the logical channel according to the second preset policy may refer to the step that the base station in the step 502 configures the SR for the logical channel according to the second preset policy. The operations of the N cache thresholds are respectively assigned to a cache identifier, which will not be further described in the embodiment of the present disclosure.

It is to be noted that, when the UE determines the cache identifier corresponding to the buffer size of the uplink data by using the foregoing second manner, the UE may directly compare the N cache thresholds with the cache size of the uplink data, and the determined cache identifier is greater than the cache identifier. The cache identifier of the cache threshold with the smallest difference between the buffer size of the uplink data and the buffer size of the uplink data, so as to ensure that the UE can obtain uplink resources that are sufficient to send uplink data and acquire uplink resources from the base station. Less waste, improving the reliability and efficiency of the UE to acquire uplink resources.

In step 602, the UE sends an SR to the base station, where the SR carries the cache identifier.

In step 603, the base station receives the SR sent by the UE.

In step 604, the base station allocates an uplink resource for transmitting the uplink data to the UE based on the cache identifier.

The method of determining the cached identifier by the UE may include the foregoing two methods. The manner in which the base station allocates uplink data to the UE according to the cache identifier determined by the different manner is also different. Therefore, the base station sends the uplink identifier to the UE according to the cache identifier. The operation of allocating uplink resources for transmitting uplink data may include the following two methods.

(1) determining, from the N+1 buffer intervals corresponding to the stored target logical channel, a buffer interval having the same interval identifier as the cache identifier, wherein the N+1 buffer intervals respectively correspond to an interval identifier; to the UE Allocating the maximum uplink resource indicated by the determined buffer interval.

As shown in FIG. 4, after transmitting the RRC message to the UE, the base station determines N+1 buffer intervals by using N cache thresholds, and allocates an interval identifier according to the first preset policy for each buffer interval. The base station may determine, according to the cache identifier, a buffer interval that is the same as the cache identifier from the N+1 cache intervals corresponding to the stored target logical channel.

In addition, because the cache identifier is used, the base station can only know the buffer interval in which the buffer size of the uplink data is located, and the specific cache size of the uplink data cannot be determined. Therefore, in order to ensure that the subsequent UE can The uplink data can be sent at one time, and the base station can allocate the maximum uplink resource indicated by the determined buffer interval to the UE.

For example, the buffer interval determined by the base station based on the cache identifier is (A1, A2), and the maximum uplink resource indicated by the buffer interval is A2. Therefore, the maximum uplink resource allocated by the base station to the UE is an A2 size uplink resource.

(2) The base station determines, according to the cache identifier, a buffer threshold corresponding to the cache identifier from the N cache thresholds included in the SR configuration of the stored target logical channel, and allocates, to the UE, the uplink resource indicated by the determined cache threshold.

As shown in FIG. 5, after transmitting the RRC message to the UE, the base station allocates a cache identifier according to the second preset policy by using each cache threshold of the N cache thresholds. Therefore, the base station can store the cache identifier based on the cache identifier. The cache threshold corresponding to the cache identifier is determined by the N cache thresholds included in the SR configuration of the target logical channel.

In addition, the base station may allocate, to the UE, the uplink resource indicated by the determined buffer threshold, because the cache identifier is a cache identifier that is greater than a buffer size of the uplink data and has a smallest difference from the cache of the uplink data. The uplink resource enables the UE to send uplink data in one time, and reduces waste of uplink resources.

In step 605, the UE receives the uplink resource sent by the base station.

In the embodiment of the present disclosure, the N cache thresholds may be used to indicate that the cache state is not triggered. Report the BSR. Therefore, when the UE receives the uplink resource sent by the base station, the uplink data may be sent by using the uplink resource.

In the embodiment of the present disclosure, the SR configuration sent by the base station to the UE may include N cache thresholds. When there is uplink data to be transmitted in the target logical channel of the UE, and there is no uplink resource for transmitting uplink data, the UE The cache size of the uplink data to be transmitted may be determined according to the N cache thresholds, and the cache identifier indicating the cache size of the uplink data is carried in the SR, so that the base station sends the uplink resource once when receiving the cache identifier. The UE is allocated to the UE, which improves the accuracy and efficiency of the UE acquiring uplink resources.
