Subframe allocation method, processing method and device thereof

Abstract

The embodiment of the invention discloses a subframe allocation method, a processing method and a device. The subframe allocation method comprises the following steps: searching for available nodes on a subframe tree when a subscriber reference signal (SRS) is configured with a subframe; and selecting an available node from the available nodes as an SRS subframe configuration node of the subscriber. In the embodiment of the invention, the subframe configuration is performed on the SRS of the subscriber based on the structure of the subframe tree and the identification of the subframe tree node, thus avoiding conflict when the subframe configuration is performed on the SRSs of different subscribers, and improving the success rate of the subframe configuration; furthermore, the structure based on the subframe tree can be flexibly expanded and contracted according to the subframe configuration condition, thus improving the subframe configuration performance of a system.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a subframe allocation method, processing method and device. Background technique [0002] The LTE (Long Term Evolution) system is the evolution of 3G (Third Generation, the third generation). It improves and enhances the 3G air access technology, improves the performance of cell edge users, increases cell capacity and reduces system delay. The LTE system adopts OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) and MIMO (Multiple-input Multiple-output) as the only standard for its wireless network evolution. In the LTE system, the UE (user side) periodically sends SRS (Sounding Reference Signal) to the eNodeB (base station side). The eNodeB can estimate the uplink CQI (Channel Quality Indicator) and the uplink of the UE by measuring the SRS signal. Timing etc. Among them, the allocation of SRS resources includes the configura...

Problems solved by technology

[0003] In the process of researching the existing technology, the inventor found that the existing technology adopts a linked list structure, and configures SRS subframes for users in sequence according to the size of the subframe period. When the user-level SRS subframe period is configured as 5, the offset is configured as After 0, if the subsequent user-level SRS subframe period is configured as 10 and the offset is 0, since the subsequent user-level SRS subframe period is a subset of the previous user-level SRS subframe period, two user-level SRS It is configured on the same subframe, so that the subframe configuration collides, so it has to search forward for a suitable subframe on the linked list, which increases the complexity of subframe configuration
