Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a UE baseband merging prediction method according to an embodiment of the present application. The identification method includes steps S1 through S3.
And S1, collecting the channel quality of the UE in different RUs.
S2, selecting an RU with the best channel quality for the same preamble ID, and marking as RU _ select, and listing part or all of the rest detected with the same preamble ID as the neighboring RU list of RU _ select.
S3, the UE performs baseband combination, and only acquires information in the neighboring RU list corresponding to the RU _ Select of the current UE during combination.
The baseband combination method provided by the above embodiment collects the channel quality of the RU; selecting an RU with the best channel quality for the same preamble ID, recording the RU as RU _ select, and listing part or all of the rest detected same preamble ID as an adjacent RU list of RU _ select; and the UE executes baseband combination, and only acquires the information in the adjacent RU list corresponding to the RU _ Select of the current UE during combination. According to the method and the device, when the base bands are combined, one adjacent RU list with good channel quality is maintained firstly, then the base bands are combined, and only the information in the adjacent RU list corresponding to the RU _ Select of the current UE is used during combination, so that the accuracy, the timeliness and the transmission efficiency of the base band combination are improved, and the use satisfaction degree of a user is improved.
In an alternative embodiment, the channel techniques of the RUs in the neighboring RU list are sorted when the next remaining part of the RU detecting the same preamble ID is listed as the neighboring RU list for RU _ select in step S2.
In this embodiment, the number of RUs in the adjacent RU list is a fixed predetermined number or all RUs having a channel quality higher than a predetermined value. For example, the fixed preset number is 5, and all RUs whose channel quality is higher than the set value are all RUs whose channel quality is above a certain threshold.
In an alternative embodiment, step S2 is followed by maintaining an inactivity timer for each RU in the neighboring RU list, and deleting any RU if the RU is inactive for a preset time; if a new active RU exists within a preset time, the new RU is added to the neighboring RU list. And the RUs in the adjacent RU list are re-detected by the UE or the UE baseband combination reselection is successful, and the inactivity timer is restarted. The RUs in the adjacent RU list are updated by adding the inactivity timer so as to improve the real-time performance of EU access, and further improve the accuracy, timeliness and transmission efficiency of baseband combination.
When the UE baseband combination prediction method is applied to a global information acquisition scene, the global information can be acquired through an SRS channel, a PUCCH channel and a PUSCH channel. When the signals are acquired through the SRS channel and the PUCCH channel, only the RUs in the adjacent RU list are configured to demodulate and report. When the global information is collected through a PUSCH, RUs in an adjacent RU list are configured in sequence to demodulate and report. Since the information of the PUSCH channel is relatively large, RUs in the adjacent RU list are sequentially configured (i.e., RUs with high channel quality are preferentially configured) to avoid uplink congestion.
Referring to fig. 2, fig. 2 is a schematic block diagram of a UE baseband merging prediction system according to an embodiment of the present application, where the identification system may be configured in a server for executing the UE baseband merging prediction method.
