Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
In order to facilitate the reader to understand the technical solutions provided by the embodiments of the present application, some concepts related to the embodiments of the present application will be explained below.
1. Physical uplink control channel.
The English language of the physical uplink control channel is called: physical Uplink Control Channel, which may be generally abbreviated as PUCCH. The physical uplink control channel is used for carrying uplink control information (English: uplink Control Information; abbreviated: UCI) sent by UE (User Equipment; chinese: user Equipment) to a base station, wherein UCI is control information related to uplink and downlink data transmission and may include: SR (english: scheduling Request; chinese: scheduling request), HARQ (english: hybrid Automatic Repeat reQuest; chinese: hybrid automatic repeat request), ACK/NACK, CSI (english: channel State Information; chinese: channel state information), and the like.
2. And (5) an uplink resource pool.
In practical applications, the base station may generally allocate an uplink resource pool in advance for the UE in the physical uplink control channel, where the uplink resource pool may include a plurality of uplink resources located in the physical uplink control channel. In the case that the UE needs to transmit the uplink control information described above to the base station through the physical uplink control channel, the UE may select one or more uplink resources from the uplink resource pool allocated in advance for the base station to transmit the uplink control information.
In general, the uplink resource pool may be characterized by three parameters, namely, a time domain offset, a resource time domain length and a time domain period, where the time domain offset refers to a time domain length of an interval between a first uplink resource in the uplink resource pool and a time domain starting point of the wireless communication system, the resource time domain length refers to a time domain length of each uplink resource in the uplink resource pool, and the time domain period refers to a time domain length of an interval between any two adjacent uplink resources in the uplink resource pool in the time domain.
In practical applications, the base station may allocate multiple uplink resource pools for the UE in the physical uplink control channel, where the multiple uplink resource pools may correspond to different uplink control information types, for example, a certain uplink resource pool allocated by the base station for the UE may correspond to SR, another uplink resource pool allocated by the base station for the UE may correspond to HARQ, and another uplink resource pool allocated by the base station for the UE may correspond to CSI.
In practical application, the time domain bias, the resource time domain length and the time period of each uplink resource pool allocated by the base station to the UE may be different from each other.
3. And (5) neighbor cell measurement.
In order to support mobility of the UE, the UE needs to perform neighbor cell measurement, through which the UE may determine signal quality of a cell adjacent to a cell to which the UE itself is currently connected, and by comparing signal quality of a cell to which the UE is currently connected with signal quality of a cell adjacent to the cell to which the UE is currently connected, the UE may determine whether to camp on the cell to which the UE is currently connected or to which the UE is connected to the cell adjacent to the cell to which the UE is currently connected through cell handover.
In general, the neighbor cell measurement needs to occupy a certain time domain, and in the time domain occupied by the neighbor cell measurement, the UE cannot send uplink data to the base station. Therefore, if the time domain occupied by the neighbor cell measurement conflicts with the time domain occupied by the uplink resource in the uplink resource pool allocated by the base station to the UE, the UE cannot transmit uplink control information by using the uplink resource in the time domain conflict in the uplink resource pool, which affects the utilization rate of the uplink resource in the uplink resource pool pre-allocated by the base station to the UE, thereby causing waste of the uplink resource.
In view of this, the embodiment of the present application provides an uplink resource allocation method, in which whether a time domain occupied by a target UE performs neighbor measurement and a time domain occupied by each uplink resource included in a first uplink resource pool allocated to the target UE conflict with each other or not may be detected, if the time domain occupied by the target UE performs neighbor measurement and a time domain occupied by any uplink resource included in the first uplink resource pool allocated to the target UE conflict with each other, a second uplink resource pool is determined, in which, after the second uplink resource pool is determined, a time domain occupied by each uplink resource included in the second uplink resource pool and a time domain occupied by each uplink resource occupied by the target UE performs neighbor measurement may not conflict with each other, and in practical application, if a time domain occupied by some uplink resources in the first uplink resource pool allocated by the target UE and a time domain occupied by the neighbor UE conflict with each other time domain required by the time domain measurement, in a time domain occupied by the target UE is transmitted in a time domain occupied by the first uplink resources pool occupied by the target UE, and thus the time domain occupied by the uplink resources occupied by the target UE cannot be allocated to each other uplink resources in the second uplink resource pool, and the situation that the uplink resources occupied by the target UE cannot be allocated to the target UE cannot be avoided.
Next, an implementation environment related to the uplink resource allocation method provided in the embodiment of the present application will be briefly described.
As shown in fig. 1, the implementation environment may include a base station 10 and a target UE 20. The base station 10 and the target UE 20 may be connected through a communication network, and the UE 20 is any one of the cells served by the base station 10. The communication network may be a 5G (The Fifth Generation Mobile Communication Technology, fifth generation mobile communication technology) communication network, an LTE (Long Term Evolution ) communication network, or other communication networks similar to the LTE communication network or the 5G communication network.
Referring to fig. 2, a flowchart of an uplink resource allocation method provided in an embodiment of the present application is shown, where the uplink resource allocation method may be applied to the base station shown in fig. 1. As shown in fig. 2, the uplink resource allocation method may include the steps of:
step 201, the base station detects whether the time domain occupied by the target UE for neighbor cell measurement conflicts with the time domain occupied by each uplink resource included in the first uplink resource pool allocated to the target UE.
In the embodiment of the application, the base station can determine the time domain range occupied by the target UE for neighbor cell measurement.
In one possible implementation, the target UE may perform the neighbor cell measurement periodically, in which case the base station may obtain a time domain starting point of the target UE performing the neighbor cell measurement, a period of the neighbor cell measurement, and a time domain length required to be occupied by each neighbor cell measurement, and based on the obtained information, the base station may determine a time domain range required to be occupied by the target UE performing each neighbor cell measurement.
In another possible implementation, the target UE may make the neighbor measurement under the direction of the base station, in which case the base station may determine the time domain range that the target UE needs to occupy to make the neighbor measurement based on its own direction to the target UE.
In yet another possible implementation manner, the target UE may autonomously initiate the neighbor cell measurement if it determines that the target UE itself satisfies the condition of the neighbor cell measurement, the target UE may report to the base station a time domain range that needs to be occupied by the autonomously initiated neighbor cell measurement, and the base station may determine, based on the report of the target UE, the time domain range that needs to be occupied by the target UE for the neighbor cell measurement.
In addition, in the embodiment of the present application, the base station may further determine a time domain range occupied by each uplink resource in the first uplink resource pool allocated for the target UE.
As described above, the uplink resource pool can be characterized by three parameters, namely, time domain bias, resource time domain length and time period. In step 201, the base station may acquire a time domain offset, a resource time domain length, and a time period of the first uplink resource pool, and determine a time domain range occupied by each uplink resource in the first uplink resource pool based on the time domain offset, the resource time domain length, and the time period of the first uplink resource pool.
After determining the time domain range occupied by the target UE for performing neighbor cell measurement and the time domain range occupied by each uplink resource in the first uplink resource pool, the base station may determine whether the time domain occupied by the target UE for performing neighbor cell measurement conflicts with the time domain occupied by each uplink resource included in the first uplink resource pool.
The time domain conflict occupied by the target UE for neighbor cell measurement and the time domain occupied by the uplink resource refers to: the time domain range occupied by the target UE for neighbor cell measurement overlaps with the time domain range occupied by the uplink resource.
Referring to fig. 3, the time domain range occupied by the target UE for performing neighbor cell measurement is (a, b), the time domain range occupied by the uplink resource a in the first uplink resource pool is (c, d), and as shown in fig. 3, there is an overlap between the time domain range (a, b) and the time domain range (c, d), that is, there is an overlap between the time domain range occupied by the target UE for performing neighbor cell measurement and the time domain range occupied by the uplink resource a, in this case, it can be considered that the time domain occupied by the target UE for performing neighbor cell measurement conflicts with the time domain occupied by the uplink resource a.
As described above, in practical application, the base station may allocate a plurality of first uplink resource pools for the target UE, where each first uplink resource pool may correspond to a different uplink control information type. In this case, for each first uplink resource pool, the base station may acquire a time domain range occupied by each uplink resource in the first uplink resource pool, and then, based on the time domain range occupied by each uplink resource in the first uplink resource pool, the base station may determine whether a time domain occupied by the target UE for performing neighbor cell measurement conflicts with a time domain occupied by each uplink resource included in the first uplink resource pool.
Referring to fig. 4, a base station allocates two first uplink resource pools c1 and c2 for a target UE, where for each first uplink resource pool, the base station may determine whether a time domain occupied by each uplink resource included in the first uplink resource pool conflicts with a time domain occupied by the target UE for neighbor cell measurement.
As shown in fig. 4, the time domain occupied by the uplink resource a in the first uplink resource pool c1 is (c, d), the time domain occupied by the target UE for performing the neighbor cell measurement is (a, b), and since there is an overlap between the time domain (a, b) and the time domain (c, d), that is, the time domain occupied by the target UE for performing the neighbor cell measurement overlaps with the time domain occupied by the uplink resource a, in this case, the time domain occupied by the target UE for performing the neighbor cell measurement may be considered to collide with the time domain occupied by the uplink resource a.
As shown in fig. 4, the time domain range occupied by each uplink resource in the first uplink resource pool c2 does not overlap with the time domain range (a, b) occupied by the target UE for performing neighbor cell measurement, so that the time domain occupied by the target UE for performing neighbor cell measurement can be considered to be not in conflict with the time domain occupied by any uplink resource in the first uplink resource pool c 2.
Step 202, if the time domain occupied by the target UE for neighbor cell measurement conflicts with the time domain occupied by any uplink resource included in the first uplink resource pool, the base station determines a second uplink resource pool.
Under the condition that the time domain occupied by the target UE for neighbor cell measurement conflicts with the time domain occupied by any uplink resource contained in the first uplink resource pool, the target UE cannot utilize the uplink resource with the time domain conflict in the first uplink resource pool. As illustrated in fig. 3, the time domain occupied by the target UE for performing the neighbor cell measurement collides with the time domain occupied by the uplink resource a in the first uplink resource pool, and since the target UE cannot send uplink data to the base station in the time domain occupied by the neighbor cell measurement, the target UE cannot send uplink control information to the base station by using the uplink resource a.
Because the target UE cannot utilize the uplink resources in the first uplink resource pool in the time domain collision, the utilization rate of the uplink resources in the first uplink resource pool is affected, so that the waste of the uplink resources is caused.
To avoid the adverse effects described above, in step 202, the base station may redetermine a second uplink resource pool for the target UE, where the time domain occupied by each uplink resource included in the second uplink resource pool does not conflict with the time domain occupied by the target UE for performing neighbor cell measurement. In the subsequent step, the base station can replace the first uplink resource pool with the second uplink resource pool to be allocated to the target UE, so that the situation that some uplink resources in the uplink resource pool allocated to the target UE by the base station cannot be utilized by the target UE due to the influence of neighbor cell measurement can be avoided, the utilization rate of the uplink resources is improved, and the waste of the uplink resources is avoided.
As described above, in practical application, the base station may allocate a plurality of first uplink resource pools for the target UE, where each first uplink resource pool may correspond to a different uplink control information type. In this case, if the time domain occupied by any one uplink resource in the target first uplink resource pool in the plurality of first uplink resource pools allocated by the base station for the target UE collides with the time domain occupied by the target UE for performing neighbor cell measurement, the base station may determine the second uplink resource pool from a plurality of available uplink resource pools preset to correspond to the target uplink control information type, where the target first uplink resource pool corresponds to the target uplink control information type.
For example, if the time domain occupied by any uplink resource in the first uplink resource pool corresponding to the SR collides with the time domain occupied by the target UE for performing neighbor cell measurement, the base station may determine the second uplink resource pool from a plurality of preset available uplink resource pools corresponding to the SR.
And 203, the base station replaces the first uplink resource pool with the second uplink resource pool to be distributed to the target UE.
According to the uplink resource allocation method provided by the embodiment of the invention, whether the time domain occupied by the target UE for neighbor cell measurement conflicts with the time domain occupied by each uplink resource contained in the first uplink resource pool allocated to the target UE is detected, if the time domain occupied by the target UE for neighbor cell measurement conflicts with the time domain occupied by any uplink resource contained in the first uplink resource pool allocated to the target UE, a second uplink resource pool is determined, wherein the time domain occupied by each uplink resource contained in the second uplink resource pool does not conflict with the time domain occupied by each uplink resource occupied by the target UE for neighbor cell measurement, after the second uplink resource pool is determined, the second uplink resource pool can be replaced with the first uplink resource pool to be allocated to the target UE, and in practical application, if the time domain occupied by some uplink resources in the first uplink resource pool allocated by the target UE conflicts with the time domain occupied by the neighbor cell measurement, the UE cannot send uplink data to the base station in the time domain occupied by the neighbor cell measurement, so that the time domain occupied by the first uplink resources in the first uplink resource pool cannot be used by the base station, and the uplink resources in the second uplink resource pool cannot be allocated to the target UE, and the situation that the time domain occupied by the uplink resources in the second uplink resource pool cannot be allocated by the target UE cannot be avoided.
Referring to fig. 5, in an alternative embodiment of the present application, the base station may detect whether a time domain occupied by a target UE for performing neighbor cell measurement conflicts with a time domain occupied by each uplink resource included in the first uplink resource pool based on the following technical process. As shown in fig. 5, the technical process may include the steps of:
step 501, the base station determines an observation time domain range according to the first uplink resource pool and neighbor cell measurement performed by the target UE.
In practical applications, the uplink resources included in the first uplink resource pool have periodic characteristics, and the neighbor cell measurement performed by the target UE generally has periodic characteristics, so the base station can determine an observation time domain range based on the periodic characteristics, and can achieve the purpose of determining whether the time domain occupied by each uplink resource included in the first uplink resource pool conflicts with the time domain occupied by the target UE for neighbor cell measurement by determining whether the time domain occupied by each uplink resource located in the observation time domain range in the first uplink resource pool conflicts with the time domain occupied by the target UE for neighbor cell measurement. Because only the uplink resource in the observation time domain is judged, the calculation amount of the base station can be greatly reduced, and the calculation time delay of the base station is reduced.
Wherein in an alternative embodiment of the present application, the technical process of determining the observed time domain range may comprise the following steps a to E.
A. The base station determines a first time domain period of a first uplink resource pool.
The first time domain period is a time domain length of a space between two adjacent uplink resources in a time domain in the first uplink resource pool.
As described above, the base station may allocate a plurality of first uplink resource pools to the target UE, in which case the base station may determine a first time domain period of each first uplink resource pool.
B. The base station determines a second time domain period of the wireless communication system in which the target UE is located.
In practical applications, the wireless communication system may generally include an uplink timeslot in which the UE may transmit uplink data to the base station and a downlink timeslot in which the base station may transmit downlink data to the UE. Therefore, if the time domain range of a certain uplink resource in the first uplink resource pool just falls within the downlink timeslot of the wireless communication system, the certain uplink resource cannot be utilized by the target UE. In view of this, in determining the observed time domain range, the base station needs to introduce a second time domain period of the wireless communication system, where the second time domain period is a time domain length spaced by two uplink time slot sets adjacent in the time domain in the wireless communication system, where each uplink time slot set includes a plurality of uplink time slots adjacent in the time domain.
C. And the base station determines a third time domain period of neighbor cell measurement by the target UE.
The third time domain period is the time domain length of the interval between two adjacent neighbor cell measurements of the target UE.
D. And the base station determines the length of the observation time domain according to the first period, the second period and the third period.
In an alternative embodiment of the present application, the base station may calculate a target least common multiple of the first period, the second period, and the third period, and use the calculated target least common multiple as the observed time domain length.
As described above, the base station may allocate a plurality of first uplink resource pools to the target UE, in which case, for each first uplink resource pool, the base station may calculate a candidate common multiple of a first period and a second period of the first uplink resource pool, then, the base station may use a largest candidate common multiple of the plurality of candidate common multiples as a candidate period, and then, the base station may use a minimum common multiple of a third period and a candidate period as the target common multiple.
E. The base station determines an observation time domain range based on the observation time domain length.
In an optional embodiment of the present application, the base station may determine a time domain starting point of the observation time domain range based on the time domain bias of the first uplink resource pool and the time domain starting point of the neighbor cell measurement performed by the target UE, and then, the base station may determine the observation time domain range according to the time domain starting point of the observation time domain range and the observation time domain length.
Step 502, the base station detects whether the time domain occupied by each uplink resource located in the observation time domain range in the first uplink resource pool conflicts with the time domain occupied by the target UE for neighbor cell measurement.
Referring to fig. 6, in an alternative embodiment of the present application, the base station may determine the second uplink resource pool from a plurality of preset available uplink resource pools corresponding to the target uplink control information type based on the following technical procedure. As shown in fig. 6, the technical process may include the steps of:
in step 601, the base station determines a plurality of candidate uplink resource pools from a plurality of available uplink resource pools.
The time domain occupied by each uplink resource in the candidate uplink resource pool is not in conflict with the time domain occupied by the target UE for neighbor cell measurement.
Step 602, the base station determines a second uplink resource pool from the multiple candidate uplink resource pools according to the resource occupancy rate of each candidate uplink resource pool.
In practical applications, the same uplink resource may be allocated to multiple UEs, where the multiple UEs may send uplink control information to the base station through the uplink resource when needed, and in general, the more UEs are allocated with uplink resources, the lower the likelihood that the UEs can successfully transmit uplink control information through the uplink resource, the fewer the UEs are allocated with uplink resources, and the higher the likelihood that the UEs can successfully transmit uplink control information through the uplink resource.
In view of the foregoing, after determining the plurality of candidate uplink resource pools, the base station may determine, from the plurality of candidate uplink resource pools, a second uplink resource pool according to a resource occupancy rate of each candidate uplink resource pool, where the resource occupancy rate of the candidate uplink resource pool is used to characterize a situation that uplink resources in the candidate resource pool are occupied by other UEs, and optionally, in an alternative embodiment of the present application, the resource occupancy rate of the candidate uplink resource pool may be obtained according to the number of UEs occupying uplink resources in the candidate resource pool.
In an optional embodiment of the present application, the base station may determine a preliminary uplink resource pool according to a time domain resource occupancy rate of each candidate uplink resource pool, where the time domain resource occupancy rate of the candidate uplink resource pool is used to characterize a situation that a time domain of an uplink resource in the candidate resource pool is occupied by other UEs. And then, the base station can determine a plurality of uplink resources to be selected from a plurality of uplink resources included in the prepared uplink resource pool based on the frequency domain resource occupancy rate of the prepared uplink resource pool, wherein the frequency domain resource occupancy rate is used for representing the situation that the uplink resources of each frequency band in the prepared uplink resource pool are occupied by other UE. Then, the base station may determine the target code channel based on the code resource utilization of the reserved uplink resource pool, where the code resource utilization is used to characterize the situation that each code channel in the uplink resource to be selected is occupied by other UEs. Finally, the base station can determine a second uplink resource pool based on the uplink resource to be selected and the target code channel.
