Embodiment Construction

[0032] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0033] It is mentioned in related technologies that if MBMS services are not transmitted on MBSFN subframes, all configurable MBSFN subframe resources will be wasted, that is, nearly half of a wireless frame will be wasted under certain uplink and downlink ratios Downlink scheduling resources. In today's era when wireless resources are so scarce, it is a pity to waste these wireless resources.

[0034] In order to solve the above technical problems, the embodiment of the present invention provides a method for sending unicast services, which uses MBSFN subframes to transmit unicast services, and its processing flow is as follows figure 1 Shown:

[0035] Step S102, the MBSFN reserved cell determine...

Abstract

The invention discloses a device and a method for sending unicast services. The method includes: an MBSFN (multimedia broadcast single-frequency network) reserved cell determines cell reference signal transmitting power for the MBSFN reserved cell according to cell reference signal transmitting power of cells adjacent to the MBSFN reserved cell; the MBSFN reserved cell determines traffic channel transmitting power for the MBSFN reserved cell according to the determined cell reference signal transmitting power of the MBSFN reserved cell; and the MBSFN reserved cell sends unicast services on MBSFN subframes according to the determined traffic channel transmitting power and the cell reference signal transmitting power of the MBSFN reserved cell. Using the device and the method for sending unicast services can solve the problem of waste of matchable MBSFN subframes caused by the fact that MBMS (multimedia broadcast multicast service) is not transmitted on the MBSFN subframes in the MBSFN reserved cell.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for sending unicast services. Background technique [0002] MBMS (Multimedia Broadcast Multicast Service, Multimedia Broadcast / Multicast Service) is an important feature introduced by the 3GPP organization in the R6 version. Services, so that network (including core network and access network) resources are shared, and services (such as: multimedia services, etc.) are simultaneously provided for a large number of users with the same needs with less resources. Wherein, MBMS in LTE (Long Term Evolution, long term evolution system) is called E-MBMS. [0003] MBSFN is a multi-cell transmission mode of MBMS, called a single frequency network transmission mode (MBSFN transmission mode), which is to perform synchronous transmission in multiple cells at the same time at the same frequency. Using this transmission mode can save frequency resources and improve spect...
