Problems solved by technology

[0004] In the prior art, the SRS resources allocated by the eNodeB to the UEs in the cell are fixed. If the SRS listening bandwidth allocated by the eNodeB to the UEs in the cell is too large, although it is beneficial for the eNodeB to schedule the UE uplink frequency domain resources, but The number of users that can be accommodated in the cell is small; if the SRS listening bandwidth allocated by the eNodeB to the UE in the cell is too small, although the number of users that can be accommodated in the cell is large, it is not conducive to the eNodeB to use the UE uplink frequency domain resources scheduling
Therefore, in the prior art, the eNodeB cannot reasonably configure the SRS resources of the UE, resulting in the disadvantage of inefficient use of SRS resources

Embodiment 1

[0027] An embodiment of the present invention provides a method for adjusting the bandwidth of an intercepting reference signal, such as figure 1 As shown, the method includes:

[0028] Step 101: Obtain the total amount of SRS resources currently allocated in the cell;

[0029] Among them, it should be understood that the operation of obtaining the total amount of SRS resources currently allocated in the cell in step 101 can be triggered multiple times, and the trigger condition is determined by the designer; the execution of step 101 can also be performed in the cell Step 101 is triggered after the newly added UE allocates SRS resources, or after the UE in the cell releases the SRS resources, or other conditions trigger the execution of step 101 , which is not limited in this embodiment of the present invention.

[0030] It should also be understood that the total amount of SRS resources currently allocated to the cell in step 101 may be: the sum of SRS resources allocated b...

Embodiment 2

[0043] An embodiment of the present invention provides a method for adjusting the bandwidth of an intercepting reference signal. This method is based on the same concept as that of Embodiment 1, but Embodiment 2 is a more specific implementation solution, which adds trigger execution adjustment (including: increasing or Reduce) the condition of SRS resource allocation, such as after allocating SRS resources for the UE, it is judged whether the allocation threshold is exceeded, and subsequent judgment is made to determine whether the SRS resource allocated for the UE needs to be reduced; or if the SRS resources of the UE are released, it is judged whether If it is lower than the release threshold, it is subsequently judged whether it is necessary to increase the SRS resource allocated to the UE in the cell.

[0044] The method provided in Embodiment 2 of the present invention is specifically described, such as Figure 2a shown, including:

[0045] Step 201: When the SRS (Sound...

Embodiment 3

[0058] The embodiment of the present invention provides a method for adjusting the bandwidth of an intercepting reference signal, which is similar to the second embodiment, except that the SRS resource allocated to the UE in the method provided by the third embodiment is more specific and complete.

[0059] Such as image 3 As shown, the method includes:

[0060] Step 301: When the SRS, Sounding Reference Signal (SRS, Sounding Reference Signal) resource to be allocated to the UE in the cell is the bandwidth value m SRS，b Afterwards, acquiring the total amount of SRS resources currently allocated in the cell, the total amount of SRS resources including the SRS resources currently to be allocated for the UE;

[0061] Step 302: Determine whether the total amount of SRS resources currently allocated is greater than the allocation threshold R SRS， alloc ; If not, execute step 303; if yes, execute step 304;

[0062] Step 303: Take the bandwidth value m SRS，b The SRS resource al...

Abstract

The invention discloses a method for adjusting intercepting reference signal band width. The method for adjusting the intercepting reference band width regulates SRS resources allocated to a UE by obtaining currently allocated total SRS resource quantity in a cell according to a utilization condition of the SRS resource. Thus, when the SRS resource utilization rate is high, the SRS resources allocated to the UE are properly reduced and services are available to more UEs. When the SRS resources are surplus, more SRS resources are allocated to the UE in the cell. The UE can properly get a better communication service. Thus, the method for adjusting the intercepting reference band width can allocate the SRS resources to the UE according to the SRS resource utilization rate and provides more intelligent services by taking demands of the cells and users into account. The SRS resources are reasonably allocated. The optimal scheduling of UE upstream frequency domain resources by an eNodeB is achieved and functions of downlink beam shaping and upstream out-of-step detection are ensured.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and a device for adjusting the bandwidth of an intercepting reference signal. Background technique [0002] Corresponding to the long-term evolution (LTE, Long Time Evolution) uplink transmission technology, the frequency band occupied each time in the data transmission of the user equipment (UE, User Equipment) is very limited, and in order to realize the scheduling on the uplink frequency domain, the base station (eNodeB ) expects to obtain channel quality information of each UE in the uplink frequency domain within a whole range or a specific range. Therefore, in addition to sending a mediation reference signal within its own data transmission bandwidth, the UE also needs to additionally send a sounding reference signal (SRS, Sounding Reference Signal) on other frequency bands for downlink beamforming and UE uplink out-of-sync detection. [0003] Although the ...
