And S3, the UE performs baseband combination, and only acquires information in an adjacent RU list corresponding to the RU_select of the current UE during combination.
The baseband combining method provided in the above embodiment collects the channel quality of RU; selecting one RU with the best channel quality for the same preamble ID, marking 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 performs baseband merging, and only acquires information in a neighbor RU list corresponding to the RU_select of the current UE during merging. In the application, when the baseband is combined, an adjacent RU list with good channel quality is maintained first, and then the baseband is combined, and only the information in the adjacent RU list corresponding to the RU_select of the current UE is used in the combination, thereby improving the accuracy, timeliness and transmission efficiency of the baseband combination and improving the use satisfaction of users.
In an alternative embodiment, in step S2, when the portion of RU whose identical preamble ID is detected next time is listed as the neighbor RU list for ru_select, the channel techniques of RU in the neighbor RU list are ordered.
In this embodiment, the number of RUs in the neighbor RU list is a fixed preset number or all RUs whose channel quality is higher than a set value. For example, the fixed preset number is 5, and all RUs with channel quality higher than the set value are all RUs with channel quality above a certain threshold.
In an alternative embodiment, after step S2, maintaining an inactivity timer for each RU in the neighbor RU list, and deleting any RU that is inactive for a preset time; if a new active RU exists within the preset time, adding the new RU to the adjacent RU list. The RUs in the neighbor RU list are re-detected by the UE or the UE baseband combining and reselection are successful, the inactivity timer is restarted. And updating RUs in the adjacent RU list by adding an inactivity timer so as to improve the real-time performance of EU access and improve the accuracy, timeliness and transmission efficiency of baseband merging.
When the UE baseband combined prediction method is applied to a global information acquisition scene, global information can be acquired through SRS channels, PUCCH channels and PUSCH channels. When the SRS channel and the PUCCH channel are acquired, only RUs in the adjacent RU list are configured for demodulation and reporting. And when global information is collected through the PUSCH, sequentially configuring RUs in the adjacent RU list to demodulate and report. Since the information of the PUSCH channel is relatively large, the RUs in the neighbor RU list are sequentially configured (i.e., the RUs with high channel quality are preferentially configured) to avoid uplink congestion.
