Problems solved by technology

[0006] In the scheduling queue of eUEs with the same priority, the eUEs are arranged in the order of time when the eNode B receives the eUE uplink resource request message, and the randomness of the eUE sending the request message to the eNode B will lead to the randomness of the order of the eUE, and then the eNode When B allocates uplink resources for eUE, there is no regular connection between eUEs corresponding to continuous uplink resources. Therefore, there is no regular connection between eUEs received by eNode B on continuous uplink resources. When sending the TPC of the eUE on the downlink resource after the continuous uplink resource, if the eNode B determines to use the cells of the DCI3 / 3A format to send the TPC, it will need to send multiple cells of the DCI3 / 3A format to pass through the The above-mentioned cells inform eUEs with different TPC-RNTIs of the TPCs corresponding to the eUEs, resulting in a large number of cells in DCI3 / 3A format and occupying more PDCCH resources.

Embodiment Construction

[0042] Hereinafter, the implementation of the eUE scheduling method and apparatus according to the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0043] figure 1 A schematic flowchart of an eUE scheduling method according to an embodiment of the present invention, such as figure 1 shown, including:

[0044] Step 101: The eNode B receives the uplink resource request message sent by the eUE.

[0045] The request message may be received by using a related technology in the prior art, which will not be repeated here.

[0046] Step 102: According to the uplink resource request message, the eNode B calculates the priority of the eUE.

[0047] The calculation of the priority of the eUE may be performed by using the related technology in the prior art, which will not be repeated here.

[0048] Step 103: Determine whether the scheduling queue corresponding to the priority of the eUE is empty, if not, go to Step 104; i...

Abstract

The invention discloses a scheduling method of eUE which comprises the following steps: according to the priority of the eUE, determining whether a scheduling queue corresponding to the eUE priority is empty or not, if not, searching whether an eUE group that is the same as TPC-RNTI of the eUE exists or not in the scheduling queue, if yes, the eUE is added to the eUE group; and if not, the eUE isadded to the tail of the scheduling queue. The invention also discloses a scheduling device of the eUE, and the method and the device can reduce the occupancy of PDCCH resource in the power control process to the eUE.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a scheduling method and device for an evolved terminal eUE. Background technique [0002] LTE (3GPP Long Term Evolution) is a next-generation evolution technology of 3G. At present, the global mobile communication industry places high hopes on LTE, expecting this technology to enhance the ability of the mobile communication industry to develop continuously. [0003] In the LTE system, the evolved base station eNode B generally schedules uplink resources for each eUE for transmission of uplink data of the eUE; and, the eNode B also according to the signal-to-noise ratio (SNR, Signal to Noise Ratio (SNR) of the uplink signal in the uplink data transmission of the eUE) Noise Ratio), controls the transmit power used by each eUE uplink data transmission, and the transmit power is the transmit power corresponding to the Physical Uplink Shared Channel (PUSCH, Phys...
