Problems solved by technology

[0008] However, in this solution, due to the wireless mobile environment, the interval for the UE to transmit signals intermittently on the uplink DPCCH cannot be too long
Because if the interval is too long, there may be a problem of out-of-sync between the base station and the UE
The short interval time will limit the system gain, and cannot maximize the saving of air interface resources, so that the number of online users of the packet service cannot be maximized

Embodiment Construction

[0034] Since the base station side needs to receive the uplink signal sent by the UE through the receiving window, and the UE is mobile, this mobility is manifested by the base station side as a change in the arrival time of the UE's uplink signal. If the UE continuously sends an uplink signal to the base station, the base station may adjust a corresponding receiving window according to the signal, so as to ensure that the receiving window can always receive the uplink signal of the UE when the UE moves. However, if the UE does not send uplink signals continuously and the interval is long, it is likely that the arrival time of the uplink signal sent by the UE will move out of the receiving window. In this case, the base station cannot normally receive the uplink signal from the UE. ? Box line lotus root cattle ?

[0035] In view of this situation, the main idea of ​​the solution of the present invention is: for a UE that enters an idle state, that is, transmits uplink signals ...

Abstract

The invention relates to a method for transmitting ascending signal, used in the wireless network with user device and base station, while user device will discontinuously send ascending signal to the base station, after enters into idle state, wherein said method comprises: a, base station confirms the idle state of user device, adds protective window on the receiving window of user device in base station; b, base station in the receiving window receives the ascending signal from user device. The invention can prolong the sending distance time of ascending signal of user device most, to reduce its interference on other devices, etc.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to an uplink signal transmission method. Background technique [0002] At present, there are more and more types of wireless communication services, and their data transmission is also varied. For example, some services need to transmit data continuously, some services need to transmit data intermittently, and some services require sporadic data transmission for a long time. [0003] For those services that do not need to continuously transmit data, if the network maintains the same state regardless of whether the service currently has data transmission, that is, when there is no data transmission, the connection allocated for the service is also reserved. It will be a waste of network resources. In addition, in the existing wideband code division multiple access (WCDMA) protocol, when the user equipment (UE) is in the online connection (CELL_DCH) state, the...
