Problems solved by technology

[0009] (2) A user's SRS can only be sent in a certain symbol of a certain subframe, and the user's PUSCH may be scheduled in any uplink subframe, if there is time-varying external interference, or the external interference is in different subframes Or the symbol strength is different, the interference situation of the user SRS and the user's PUSCH will be different
[0010] To sum up, the SINR measured by SRS symbols cannot accurately represent the SINR of the user's PUSCH channel, and it is not conducive to select the SINR for the user when the SINR obtained by SRS measurement is used for frequency selection scheduling. optimal subband

Embodiment Construction

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0027] The current uplink frequency selection scheduling method of the base station is as follows: the base station configures periodic SRS resources for each user to ensure that the user periodically sends SRS signals for the base station to measure; The degree is divided into multiple subbands, each subband is calculated to obtain a SINR; when the base station scheduler allocates uplink PRB resources for users, according to the SINR of each subband of the user, within the available resources of the system, select the bearer Continuous ...

Abstract

The embodiment of the present invention proposes a method for uplink scheduling, including the following steps: configure the SRS frequency band for the user, and periodically receive the SRS signal sent by the user; calculate the useful signal power of the user according to the SRS signal, and respectively Calculate the interference noise power of the corresponding frequency band, calculate the SINR of the corresponding frequency band; allocate uplink transmission resources for users according to the SINR of the corresponding frequency band. On the other hand, the embodiment of the present invention also proposes an uplink scheduling device. The above scheme proposed by the present invention can effectively avoid the problem of inaccurate SINR measurement by SRS in the prior art, thereby effectively realizing the accurate calculation of the SINR of the user PUSCH channel, and based on the SINR of the obtained frequency band The ratio can accurately and faithfully reflect the situation of the uplink PUSCH channel, can accurately select the optimal frequency resource for the user, and effectively improve the system performance.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular, the present invention relates to a method and equipment for uplink scheduling. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is a long-term evolution of the UMTS technical standard formulated by the 3GPP organization. Since the LTE system introduces key transmission technologies such as OFDM and multi-antenna MIMO, the spectral efficiency and data transmission rate have been significantly increased, and it supports multiple bandwidth allocations. Spectrum allocation is more flexible, and system capacity and coverage have been significantly improved. The LTE wireless network architecture is flatter, which reduces system delay and reduces network construction and maintenance costs. LTE is a broadband communication system. The broadband channel has frequency selectivity, and signals of different frequencies experience different fading. The f...
