Problems solved by technology

[0006] Embodiments of the present invention provide a method and device for allocating uplink shared resources, which are used to solve the problem in the prior art that the resource blocks allocated by the base station to the user terminal are very large, and the transmission power of the user terminal may be insufficient, resulting in The power spectral density on the uplink shared resource is reduced, which cannot meet the data transmission requirements of the uplink service

Embodiment Construction

[0024] In the embodiment of the present invention, according to the PH value reported by the user terminal, the historical scheduling information corresponding to the PH value, the historical power control information corresponding to the PH value, the scheduling information and the current power control information of the user terminal scheduled this time, determine the current scheduling Whether the user terminal will be limited in power; according to the judgment result, determine the transmission bandwidth actually allocated when scheduling the user terminal this time, and notify the user terminal of the actual allocated transmission bandwidth. Since the embodiment of the present invention can judge whether the user terminal scheduled this time will be power-limited according to the remaining power value reported by the user terminal, and determine the transmission bandwidth actually allocated when the user terminal is scheduled this time according to the judgment result, av...

Abstract

The embodiment of the invention relates to a wireless communication technology, in particular to a method and equipment for allocating uplink shared resources. By the method and the equipment, the problem that in the prior art, the power spectral densities of the uplink shared resources cannot meet the requirement of service transmission because a resource block allocated by a base station to a user terminal is quite large but the transmitting power of the user terminal may be not large enough is solved. The method comprises the following steps of: according to a PH value, historical dispatching information, historical power control information, dispatching information of a current dispatching user terminal and current power control information, judging whether the power of the current dispatching user terminal is limited; and according to a judgment result, determining a transmission bandwidth actually allocated to the current dispatching user terminal and informing the user terminal of an actually-allocated transmission bandwidth. By the method, the uplink transmission power of the user terminal is not limited, so the service quality of each uplink service of the user terminal is improved and the capacity of the system is increased.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and equipment for allocating uplink shared resources. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the uplink data transmission of the user terminal is transmitted on the PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel), and the size of the uplink allocated shared resources and the MCS (Modulation and CodingScheme, modulation and coding scheme) levels are assigned by the base station to the user terminal. [0003] At present, the resource block size and MCS level allocated for uplink transmission of the user terminal are mainly determined based on the amount of data in the uplink buffer (buffer area) and the CQI (Channel Quality Indicator, Channel Quality Indicator) information reported by the terminal. [0004] If the resource block allocated by the base station to a user terminal is very l...
