Problems solved by technology

[0004] The method of reducing the SPS period and pre-scheduling can effectively reduce the UE uplink access delay, but it also brings another problem: the UE does not always have data to send on the allocated resources, but frequently sends unnecessary data to the eNB. The data information will consume UE power quickly
In addition, the UE needs additional uplink resources to transmit BSR, which consumes more uplink resources and causes greater power overhead

Embodiment Construction

[0085] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0086] An embodiment of the present invention provides a method for obtaining information, referring to figure 1 As shown, the method includes the following steps:

[0087] Step 101. Receive first information sent by a base station.

[0088] Wherein, the first information includes a preset threshold for the user equipment not to send data.

[0089] Specifically, receiving the first information sent by the base station may be implemented by the user equipment. The first information may be sent by the base station to the user equipment through radio resource control protocol (Radio Resource Control, RRC) signaling or PDCCH indication. The preset threshold for the user equipment not to send data may specifically be a preset threshold for allowing the user equipment not to send...

Abstract

The embodiment of the invention discloses an information acquisition method comprising steps of: receiving first information transmitted by an eNB, wherein the first information includes a preset threshold that user equipment does not transmit data; and determining whether the number of times or the ratio that the user equipment does not transmit data exceeds the preset threshold according to the first information; sending a data resource usage indication to the eNB if yes in order that the eNB obtains the service condition of the data resources of the user equipment according to the data resource usage indication. The embodiment of the invention also discloses an information acquisition device.

Description

technical field [0001] The present invention relates to information acquisition technology in the field of wireless communication, in particular to an information acquisition method and equipment. Background technique [0002] Semi-Persistent Scheduling (Semi-Persistent Scheduling, SPS) allows semi-static configuration of wireless resources to periodically allocate resources to a specific user equipment (User Equipment, UE). In short, a base station (evolved Node B, eNB) in a certain The physical downlink control channel (Physical Downlink Control Channel, PDCCH) scrambled by SPS C-RNTI in each subframe specifies the radio resource used by the UE, and the UE uses the SPS resource to send and receive data every cycle. The existing standard stipulates that the minimum period of SPS is 10ms. If the SPS cycle can be shortened, the UE can obtain uplink resources in a timely manner to realize timely data transmission and reception. [0003] Different from the SPS that periodical...
