Problems solved by technology

[0002] The era of 3G / 4G is coming to us in great strides, and the functions of terminals are becoming more and more powerful. These functions greatly enrich people's demand for entertainment, but at the same time, they also increase the power consumption of terminals.
[0011] In the energy-saving mechanism of LTE, in order to save signaling overhead, the HARQ mechanism is supported by adding retransmission activation. However, there is an unsolved problem: how to deal with signaling errors in the retransmission mechanism
This solution is relatively easy to implement, but its disadvantage is that once a NACK is mistaken for an ACK error, it will increase the energy consumption of the UE. Once an ACK is mistaken for a NACK error or the ACK is lost, the eNB will continue to retransmit data. waste of system resources

Embodiment 1

[0158] This embodiment specifically describes a discontinuous reception control method provided by the present invention, including the following steps:

[0159] Step 1: The base station device sends new data to the user device, and at the same time starts the corresponding hybrid automatic repeat request process, and adjusts the timers in the discontinuous reception mechanism accordingly;

[0160] The discontinuous reception mechanism timer in the hybrid automatic repeat request process includes a base station round-trip delay timer, a base station retransmission timer, a base station extended round-trip delay timer and a base station retransmission remaining timer;

[0161] Said starting the corresponding HARQ process is starting the round-trip delay timer at the base station;

[0162] The adjustments include:

[0163] (1) The overflow length of the extended round-trip delay timer at the base station end is set to be equal to the overflow length of the base station end roun...

Embodiment 2

[0211] This embodiment specifically describes a discontinuous reception control device provided by the present invention, including base station equipment, user equipment, base station round trip delay timer, base station retransmission timer, user end round trip delay timer . The user end retransmission timer, characterized in that the device also includes a base station end extended round-trip delay timer, a base station end retransmission remaining timer, a user end extended round-trip delay timer, and a user end retransmission remaining timer;

[0212] The extended round-trip delay timer at the base station end is used to record the minimum time interval between the feedback signal of the user end equipment and the retransmission signal transmission time of the base station end equipment, and indicates that no feedback signal from the user end equipment was received during the previous data retransmission process;

[0213] The user end extended round-trip delay timer is use...

Embodiment 3

[0233] This embodiment describes an embodiment of a DRX control device at a network end base station (eg, eNB) according to the present invention.

[0234] Such as Figure 5.1 and 5.2As shown, the DRX control timers related to the present invention at the base station include a round-trip delay timer, an extended round-trip delay timer, a remaining retransmission timer and a retransmission timer. When the base station sends new data, or sends retransmission data when there is no signaling error that the base station can detect, a round-trip delay timer will be started. If there is a signaling error that can be detected by the base station, the extended round-trip delay timer is started after the data is sent. After the round-trip delay timer overflows and receives NACK feedback or no feedback, or the extended round-trip delay timer overflows and receives NACK feedback, activate the retransmission remaining timer. During the operation of these three timers, the base station ...

Abstract

The invention relates to the field of data communication, in particular to a non-continuous receiving control method and a device. The method comprises the following steps: starting the corresponding hybrid automatic repeat request process after a user end device receives new data, carrying out the corresponding adjustment on all timers in a non-continuous receiving mechanism, and verifying the received new data, if correct, feeding back a confirmation signal to a base station end device; if wrong, feeding back a non-confirmation signal to the base station end device; adjusting the repeat process according to whether the feedback from the user end device occurs or not in the follow-up process and the type of the feedback after the base station end device sends the data; and adjusting the repeat process after the user end device completes the verification of repeat data and under various situations in the follow-up process. The method can realize the synchronization of the base station end device with the user end device under the wrong signals by increasing two new timers, thereby eliminating the affects on packet loss rate due to that part of the signals are wrong and the unnecessary waste of network resources caused by non-synchronous repeat data.

technical field [0001] The invention relates to the field of data communication, in particular to a discontinuous reception control method and device. Background technique [0002] The era of 3G / 4G is coming to us in great strides, and the functions of terminals are becoming more and more powerful. These functions greatly enrich people's demand for entertainment, but at the same time, they also increase the power consumption of terminals. As the load of portable mobile terminals powered only by batteries is getting heavier, advanced energy-saving strategies and power management systems need to be developed urgently to ensure the use time and standby time of the terminals. [0003] At present, the communication field that researches the most in terms of energy saving is the wireless sensor network. Due to the particularity of wireless sensor networks, energy saving has become a key research point and main performance index of this type of network. Various energy-saving meth...
