Embodiment Construction

[0047] The invention provides a dedicated preamble resource allocation method and device. The method includes: according to the planned dedicated preamble resources, establishing the inclusion relationship between different PRACH time-frequency domain resource configurations, calculating the resource occupancy coefficient of each PRACH mask index, and according to the inclusion relationship between the resource occupancy coefficient and the PRACH resource relationship to perform PRACH resource allocation. When allocating resources, allocate dedicated preamble resources to different users according to different methods according to user priority or user business priority; when allocating dedicated preamble resources, consider the number of remaining dedicated preamble resources and users who need dedicated preamble resources within a period of time The period of time is the usage time of the dedicated preamble resource acquired through statistics.

[0048] The dedicated preamb...

Abstract

The present invention provides a method and device for allocating dedicated preamble resources. The method includes: according to a Physical Random Access Channel (PRACH) configuration index and the current type, initializing the containing relationship between the PRACH resources indicated by different PRACH mask indexes; obtaining the resource consumption coefficient of each PRACH mask index, wherein the resource consumption coefficient is the ratio of the number of resources indicated by PRACH mask index to the number of resources indicated by the PRACH configuration index; and allocating the PRACH resources to the user equipment according to the resource consumption coefficient and the containing relationship between the PRACH resources. The present invention can rationally use limited dedicated preamble resources, effectively improve the dedicated preamble resources utilization rate, and improve user access performance and access success rate.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for LTE (Long Term Evolution, Long Term Evolution) dedicated preamble (Preamble) resource allocation. Background technique [0002] LTE is a long-term evolution technology. The random access process is the key process of LTE. Random access is divided into two types, contention random access and non-contention random access. [0003] In contention random access, a user equipment (User Equipment, UE) randomly selects a preamble to send in non-dedicated preamble resources, such as figure 1 shown. In non-competitive random access, the evolved base station (eNB) assigns a dedicated preamble and PRACH (Physical Random Access Channel, Physical Random Access Channel) opportunity to the UE, and the UE sends the specified dedicated preamble on the specified PRACH opportunity, such as figure 2 shown. For non-contention random access, the eNB notifies the UE of dedic...
