Method and system for downlink space interface signaling transmission

Abstract

The invention discloses a transmitting method of downlink gap signaling and a system thereof. The method includes the following steps: when a wireless network controller is to send the downlink gap signaling to a user terminal, the transmitting power to be adopted under the current situation of wireless links is determined according to the corresponding relationships between situations of preset wireless links and the transmitting power to be adopted; the wireless network controller sends instructions to a node B and informs the node B to transmit the downlink gap signaling by adopting the determined transmitting power; the node B transmits the downlink gap signaling by adopting the determined transmitting power according to the instructions. The system comprises the wireless network controller and the node B; wherein, the wireless network controller comprises a transmitting power determination unit and a transmitting power indication unit; the node B comprises a transmitting unit. Byadopting the method or the system, the transmitting reliability of the downlink gap signaling can be improved when the quality of the wireless links is rather poor.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and system for downlink air interface signaling transmission in the field of wireless communication. Background technique [0002] The UMTS wireless communication system, which is organized by 3GPP, is used to provide users with services with different QoS requirements. In UMTS system, how to overcome interference is an important issue. [0003] In the UMTS system, due to the bursty nature of the air interface signaling issued by the UTRAN side to the UE, it has high requirements for reliable transmission. Therefore, how to ensure faster and more reliable transmission of these important signaling to the UE , becomes extremely important. Especially when the radio link is not stable, it is likely that the UE does not receive the adjustment request from the network, resulting in call drop and other phenomena. [0004] In the prior art, the above problems can...

Problems solved by technology

However, for the first method, when the wireless link is relatively bad, although the downlink transmission power can be increased through the inner loop power control, this may cause the transmission power of the downlink wireless link to decrease for a long time. It has been kept at a relatively high level, causing strong interference to other users for a long time, and because the maximum downlink transmit power itself cannot be broken through, the UE may still be unable to receive downlink signaling when the wireless link quality is relatively poor.

For the second method, increase the maximum transmission power of the wireless link. Since this power value does not distinguish between signaling and services, it may cause the downlink transmission power of the system to always reach a higher level during the period of service transmission, thus Cause the load of the whole system to rise, which is obviously not what we want
