Embodiment 1

[0054] In the LTE system, some user equipments performing detection need to frequently send measurement reports with a small amount of data to the network side, for example, measurement data needs to be reported every 5 minutes, and the rate only needs to be 10 kbit / s. If these user equipments adopt hardware and software that meet the requirements specified in existing protocols, the cost of these user equipments will be very high, and the data transmission rate that these user equipments can achieve will far exceed their actual needs, which not only wastes manufacturing costs, but also It is not conducive to the network side to adopt efficient resource scheduling algorithms for these user equipments, resulting in waste of air interface resources.

[0055] In view of the above problems, this embodiment proposes a new user equipment, which uses a lower rate processing chip, which cannot continuously monitor the signaling on the PDCCH, and can only be separated by one subframe (i...

Embodiment 2

[0074] In the LTE system, some user equipments only need to send and receive small data occasionally, so these user equipments do not need to have strong processing capabilities. In this embodiment, the user equipments do not have the ability to continuously receive PDCCH signaling. The process of accessing the network is as follows: image 3 Shown:

[0075]In step 201, the user equipment initiates random access in the cell where it resides, and sends RRC connection request signaling to the base station to which the cell belongs.

[0076] Step 202, the base station allocates resources for the user equipment, and sends RRC connection establishment signaling to the user equipment.

[0077] Step 203: After receiving the establishment of the RRC connection, the user equipment sends RRC connection establishment completion signaling to the base station, and the signaling also includes non-access stratum signaling sent by the user equipment to the core network, for example, an attac...

Embodiment 3

[0092] Some user equipment in the LTE system are mainly used to receive or send content with a small amount of data. If such user equipment adopts hardware and software that meet the requirements of the existing protocol, the cost of these user equipment will be high, and the air interface resource Waste is also serious. Therefore, the user equipment in this embodiment only has the ability to receive a small amount of data, which is specifically reflected in the limitation of the amount of data that the user equipment can send or receive at one time. For example, the user equipment can only send or receive a maximum of 300 bits of data at a time. For the downlink, the user equipment detects its own PDCCH signaling, and then obtains parameters such as the frequency position, modulation and coding scheme of the PDSCH according to the downlink control information carried in the PDCCH signaling, and detects the PDSCH. If the amount of data that the user equipment can receive at on...

Abstract

The invention provides a method, user equipment, a base station, and a system of resource scheduling. The method of resource scheduling comprises that: the base station receives transmission capacity information reported by the user equipment; and the base station carries out resource scheduling on the user equipment according to the transmission capacity information. The resource scheduling can be carried out on user equipment with a low processing capacity according to the invention, so that user equipment which have low demands for processing performance can effectively receive the resource scheduling from the base station without adopting hardware or software needed to meet provisions of the existing protocol in some application scenarios.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a resource scheduling method, user equipment, base station and system. Background technique [0002] With the continuous improvement of people's requirements for wireless communication, wireless communication technology has developed rapidly in terms of speed, capacity and quality. In the Long Term Evolution (LTE for short) system, in order to increase the rate of data transmission, the user equipment (User Equipment, UE for short), that is, the terminal, is required to have strong processing capabilities, such as continuous monitoring of the physical downlink control channel ( The Physical Downlink Control Channel (PDCCH for short) needs to support 64QAM (Quadrature Amplitude Modulation) coding capability in the downlink. In order to reduce the delay of user equipment accessing the network and enhance user experience, the agreement stipulates that the delay of LTE term...
