Problems solved by technology

[0004] When analyzing the existing technical solutions, the inventor found that if there is uplink data to be sent during the sleep period, the UE will wait until the on duration of the next DRX cycle arrives before waking up, and then perform uplink transmission. The on-duration interval is relatively long, and the services that the UE needs to send are relatively urgent (such as some measurement reports used in handover, etc.), there may be problems such as wireless link failure due to these services not being processed in time

Embodiment Construction

[0014] Embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0015] see figure 1 , figure 1 It is a flowchart of an uplink sending method in a discontinuous reception state provided by an embodiment of the present invention.

[0016] In step 102, the user equipment detects that there is an uplink radio bearer service waiting to be sent during the sleep period in the DRX state.

[0017] The specific implementation manner that the user equipment detects that there is an uplink radio bearer service waiting to be sent may be: in the buffer area of ​​PDCP (Packet Data Convergence Protocol, packet data convergence layer protocol) or in the buffer area of ​​RLC (Radio Link Control, radio link control) detected data.

[0018] In step 104, the user equipment compares the priority of the radio bearer service to be sent with the sending priority threshold.

[0019] In order to ensure that some uplink services can be...

Abstract

The embodiment of the invention provides an uplink sending method under the DRX (Discontinuous Reception ) state, comprising the following steps of: detecting an uplink wireless bearer service to be sent in the Sleep mode under the DRX state; waking up a user facility and requesting to assign uplink sending resources, when the priority of the wireless bearer service to be sent is higher than or equal to the threshold of the sending priority; and sending the wireless bearer service to be sent by utilizing the assigned uplink sending resources. The embodiment of the invention further provides a user facility. The embodiment of the invention can lead the user facility to process services with high priority in time, thereby guaranteeing the normal function of the user facility.

Description

technical field [0001] The embodiment of the present invention relates to the field of wireless communication, in particular to a user equipment and an uplink transmission method in a discontinuous reception state. Background technique [0002] The power saving scheme of UE (User Equipment) has always been an important research topic in the field of wireless communication. As a new wireless access technology, the LTE (Long Term Evolved, Long Term Evolution) system also attaches great importance to research on UE power saving schemes, among which DRX (Discontinuous Reception, Discontinuous Reception) is a power saving method. [0003] The main idea of ​​DRX is to turn off the receiver and transmitter when the UE does not receive data, set the UE to sleep, and wake up the UE regularly to monitor whether there is data reception or transmission. If there is no data, the UE will continue to sleep. If there is, the UE will Receive or send data, and continue to sleep after receivi...
