Embodiment Construction

[0044] The present invention proposes a method for sending service information on DL_SCH, the core idea of ​​which is: the sending end sends MBMS information according to the start time t_start of scheduling MBMS information and the set adjustment time length delta_x; or, the sending end sends MBMS information according to the scheduling MBMS The information frequency bands X1 to X2 and the set adjustment frequency band delta_X are used to transmit MBMS information.

[0045] Correspondingly, the present invention also proposes a method for receiving service information on DL_SCH, the core idea of ​​which is: the receiving end receives MBMS information according to the start time t_start of scheduling MBMS information and the set adjustment time length delta_x; or, receives The terminal receives the MBMS information according to the frequency bands X1 to X2 for scheduling the MBMS information and the adjusted frequency band delta_X.

[0046] Wherein, after the trigger condition...

Abstract

The invention discloses a method to transmit and receive business information on DL_SCH. According to the starting time t_start of scheduling MBMS information and the set length of adjusting time delta_x, the transmitter sends MBMS information, or according to its band X1 and X2 and the set adjusting band delta_X. Correspondingly, the receiver receives MBMS information according to the above mentioned.

Description

technical field [0001] The present invention relates to network communication technology, in particular to a method for sending service information and a method for receiving service information on a downlink shared channel (DL_SCH). Background technique [0002] In order to have strong competitiveness in the wireless access technology of the 3GPP (3GPP) in the next 10 years or longer, it is necessary to consider the long-term evolution (LTE) of the 3GPP wireless access technology. The goal of LTE is to develop a framework for wireless access technologies characterized by high data rates, low response times, and optimal packet access. [0003] Currently, in LTE, an important service is to realize Multicast Multicast (MBMS) service on the Orthogonal Frequency Division Multiplexing (OFDM) multi-carrier technology. The MBMS service mainly refers to the network sending the same multimedia data to multiple receivers in the network, thereby providing a point-to-point service in w...
