UE uplink specialized resource control method

Abstract

The invention provides a UE uplink specialized resource control method. The method includes: when UE is about to enter a DRX sleep mode or after the UE enters the DRX sleep mode, an uplink specialized resource is released, and the UE enters an uplink out-of-step state. According to the method, when the ultra-long DRX is introduced, uplink specialized resources such as PUCCH and SRS etc. can be reasonably used, and the uplink capacity is increased.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a UE uplink dedicated resource control method. Background technique [0002] With the development of wireless mobile communication technology, people put forward higher and higher requirements for high speed, low delay and low cost. The LTE (Long Term Evolution) project was born under such a background, pursuing higher peak rates and shorter transmission delays. [0003] The main performance goals of the LTE project include: providing a peak rate of 100 Mbps downlink and 50 Mbps uplink in a 20MHz spectrum bandwidth, improving the performance of cell edge users and increasing cell capacity; reducing system delay, and the one-way transmission delay within the user plane is less than 5ms. The transition time of the control plane from the sleep state to the active state is less than 50ms, and the transition time from the resident state to the active state is less than 1...

Problems solved by technology

[0005] In the prior art, during the DRX sleep period, the UE maintains dedicated uplink resources such as PUCCH and SRS, but for ultra-long DRX scenarios, the sleep time of the UE may be several minutes or even longer, so during this period, the UE maintains dedicated uplink resources such as PUCCH and SRS , affecting the uplink capacity
