Method for transmitting beep-page information, transmission apparatus, receiving apparatus

Abstract

The invention belongs to the communication technical filed, and discloses a method, a transmitting device and a receiving device for transmitting paging information. The method comprises the following steps: sending a paging indication channel to a sub frame corresponding to a paging moment when the paging information is required to be transmitted at the paging moment, and the sub frame corresponding to the indication paging moment can not support the transmission of the paging information; and delaying the paging information to the sub frame which supports the transmission of the paging information after the paging moment corresponding to the sub frame. The method has the advantages that when the sub frame corresponding to the paging moment can not support the transmission of the paging information, the paging time and the sleep state of a paging user are ensured, thereby reducing the power consumption of paging, and reducing the time of the paging.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, a sending device and a receiving device for paging information transmission. Background technique [0002] In a wireless communication system, when the network does not know where the user is located, that is, the cell where the user is located, the system establishes a connection by sending paging information in the paging channel. In order to save power for the idle user, the idle user does not need to check whether there is paging information for itself every moment, but only needs to check whether there is paging information for himself at a fixed time. During the time when no paging information is detected, the idle user can be in a sleep state, so that the power consumption of the user terminal can be reduced and the standby time can be prolonged. For example, in a Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) syste...

Problems solved by technology

However, cells belonging to the same MBSFN area do not know the dynamic resource allocation of other cells except themselves, which will affect the gain of soft combining. It can be seen that the dynamic allocation of time-frequency resources to the shared data mapped by paging information channel is not feasible

[0007] If a certain time-frequency resource is reserved in the MBSFN subframe for the shared data channel mapped to the paging information, since the size of the paging information is variable, it is difficult to determine how many time-frequency resources are reserved.

If the shared data channel mapped to the paging information in a cell occupies part of the time-frequency resources of the MBSFN subframe, then this part of the time-frequency resources will not be available to all other cells in the same MBSFN area, resulting in a waste of resources

Therefore, the shared data channel to which the paging information is mapped cannot be multiplexed in the same MBSFN subframe where the paging indicator channel is located, resulting in the paging user being unable to obtain the paging information at the paging time, thus affecting the paging user's paging performance. call time and sleep state
