Method and device for allocating uplink resources in small-bandwidth system

Abstract

The embodiment of the invention provides a method and a device for allocating uplink resources in a small-bandwidth system. The method comprises the following steps: judging whether the state of a first PRB resource of a physical uplink control channel PUCCH corresponding to a current uplink subframe is an idle state or not; if the state of the first PRB resource is an idle state, adding the firstPRB resource into a resource pool of a physical uplink shared channel PUSCH corresponding to the current uplink subframe; and allocating the first PRB resource in the resource pool to the terminal equipment corresponding to the physical uplink shared channel PUSCH according to a preset rule. According to the embodiment of the invention, idle PUCCH resources in a current subframe are added to a PUSCH resource pool corresponding to the current subframe; for the scene of a small number of users with small bandwidth, used PUCCH resources are not changed, the overhead of system information changeand air interface reconfiguration messages is not needed, and the use resources of the PUSCH are dynamically expanded, so that the uplink rate is increased, and the uplink throughput of a small-bandwidth system is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method and device for allocating uplink resources in a small bandwidth system. Background technique [0002] In the LTE system, the Physical Uplink Control Channel (PUCCH) is used to carry uplink control information, and the uplink L1 / L2 control information (Uplink Control Information, UCI) includes: [0003] Uplink Scheduling Request (Scheduling Req, SR): used for the terminal to request uplink UL-SCH resources from the base station; [0004] Hybrid Automatic Repeat reQuest (HARQ) ACK / NACK: HARQ confirmation for the downlink data sent on the Physical Downlink Share Channel (PDSCH); [0005] Channel state information (Channel State Information, CSI): including channel quality information indication CQI, precoding matrix indication PMI, rank indication RI and other information, used to inform the base station of downlink channel quality, etc...

Problems solved by technology

[0013] At present, the adjustable PUCCH mode is to statically or semi-statically adjust PUCCH resources for scenarios with large bandwidth and multiple users, and the adjustment cycle is relatively long. In addition, the access and release of users on the public network have certain randomness. Periodic adjustment needs to resend system information and other parameters, resulting in high model accuracy and implementation complexity, and is not suitable for scenarios with small bandwidth and the number of individual users

In such a scenario where the number of users is small, the rate of individual users is equal to the average rate of the entire cell. If the adjustment method of the public network under a large number of users is used, the rate of individual users will be sacrificed, thereby sacrificing the overall rate of the cell.
