Physical resource allocation method and equipment

Abstract

The embodiment of the invention provides a physical resource allocation method and physical resource allocation equipment. The physical resource allocation method comprises the steps that: user equipment receives a system broadcast message or a radio resource control protocol RRC reconfiguration message sent by a base station, and the system broadcast message or the RRC reconfiguration message is used for indicating that the base station supports the user equipment at a first ability category to carry out 64 quadrature amplitude modulation QAM on uplink data; the user equipment sends the ability category and uplink modulation information of the user equipment to the base station, the uplink modulation information is used for indicating that the user equipment is supportive of carrying out the 64 QAM on the uplink data, wherein the ability category of the user equipment belongs to the first ability category, so that the base station can allocate physical resources to the user equipment according to the ability category and the uplink modulation information of the user equipment; and the user equipment receives the physical resources allocated to the user equipment by the base station, utilizes the physical resources and reports data to the base station in a 64QAM modulation manner. The physical resource allocation method and the physical resource allocation equipment can enhance cell handling capacity.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for allocating physical resources. Background technique [0002] Long Term Evolution (LTE for short) is the long-term evolution of the Universal Mobile Telecommunications System (UMTS for short) technical standard developed by the 3rd Generation Partnership Project (3GPP for short). For the data transmission rate, high-order modulation (64 Quadrature Amplitude Modulation (64QAM for short)) is introduced to obtain high spectral efficiency. [0003] In the prior art, the base station judges whether the UE can adopt the uplink 64QAM modulation mode according to the capability of the user equipment (User Equipment, UE for short). The existing UE capability level (Category) is divided into 5 levels. The 3GPPTS36.306 protocol stipulates that when the UE capability level is 1-4, the UE can perform uplink QuadriPhaseShiftKey (QuadriPhaseShiftKey...

Problems solved by technology

[0004] However, when the UE capability level is 1-4, even if the UE itself supports uplink 64QAM modulation, the UE cannot perform uplink 64QAM modulation. The base station can only allocate physical resources for the UE according to the UE capability level and QPSK modulation mode or 16QAM modulation mode. Since the data carrying capacity of the Orthogonal Frequency Division Multiplexing (OFDM) symbol is different in different modulation modes, 64QAM is higher than the QPSK modulation mode and 16QAM modulation mode, resulting in that the UE supporting uplink 64QAM cannot obtain high spectral efficiency. Cell throughput cannot be improved
