Problems solved by technology

The point of this multicast area indication method is that the overhead is very small, but there are serious shortcomings: poor flexibility; resource allocation granularity is too large, which is 4×N subframes; when resource requirements are small, on the one hand, it may Due to the problem of granularity, the allocation cannot be completed. On the other hand, due to the large granularity of resource allocation, it needs to be evenly distributed to many frames. The number of multicast broadcast service subframes in each frame is relatively small, which is not conducive to terminal power saving.

Embodiment 1

[0041]Indicate once every N superframes in the system. The N value can be changed according to the way the MBS is carried in the subframe in the system. When the MBS subframe pattern in the system is fixed, the N value is a fixed value, and the MBS subframe is The indication information corresponding to the pattern may also be a fixed value. In the present invention, 1 bit is used to indicate whether the N superframes carry a multicast broadcast service subframe, 1 indicates yes, and 0 indicates that no MBS is carried in the N superframes. When MBS is carried in N superframes, an N-bit pattern is used to describe which superframes have MBS. Each frame in the superframe whose corresponding bit is 1 has a multicast service, and the MBS subframe configuration carried by each frame is exactly the same.

[0042] The instruction information for carrying MBS is shown in Table 1:

[0043] X(1bit)

Indicates whether the N superframes have multicast services

If X=1 ...

Embodiment 2

[0058] The application scenario of this example is: when the subframe patterns for carrying MBS indicated by every N superframes in the system are not unique, it is necessary to indicate each subframe pattern for carrying MBS. In this example, the indication information of the superframe and the indication information of the subframe level are shown in Table 4:

[0059]

[0060] Table 4

[0061] In Table 4, the meanings of X, Y, and Z are exactly the same as those in Table 1, and P is an indication of the number of subframe patterns included in a superframe.

[0062] When X is 00, there is no multicast broadcast service subframe in N superframes. At this time, the N patterns are all 0, and there may be no indication information at the subframe level.

[0063] When X is 01, N superframes all include multicast broadcast service subframes, and the configuration of the subframe pattern in each superframe is the same; the multicast broadcast service area indication information...

Embodiment 3

[0072] In this example, frame-level indication information and sub-frame-level indication information are set. The default is that each superframe in the indicated superframe area carries MBS. In each superframe, the frame pattern carrying MBS is different. However, the patterns of the subframes carrying the MBS in the frame are the same. Indicate once every N superframes, use 1 bit to indicate whether the N superframes have multicast services, 1 means yes, if there are multicast services, all superframes have multicast services by default, and the configuration of the superframes is the same . Use 4bit patterns to describe which frames on the superframe have multicast services. The frame corresponding to a bit of 1 has a multicast service, and the subframe configuration of the multicast broadcast service on each frame is the same. Frame-level indication information and sub-frame-level indication information are shown in Table 5:

[0073] X: 1 bit

Indicates whe...

Abstract

The invention discloses a multicast broadcast service bearer indication method, comprising: setting subframe level and super frame level indication information of the multicast broadcast service, or subframe level and frame level indication information, and notifying user terminals. The present invention also discloses a multicast broadcast service bearer indication device, comprising: a setting module for setting subframe level and superframe level indication information, or subframe level and frame level indication information of the multicast broadcast service; A module, configured to notify the user terminal of the subframe level and superframe level indication information, or the subframe level and frame level indication information. The present invention makes the bearer of the subframe resources more flexible, and the way of resource bearer enables the user terminal to save more power.

Description

technical field [0001] The present invention relates to a multicast broadcast service (MBS, Multicast Broadcast Service) bearer mode indication technology, in particular to a multicast broadcast service region (MBS Region) in a World Interoperability for Microwave Access (WiMAX, World Interoperability for Microwave Access) network A method and device for indicating MBS bearer in ). Background technique [0002] MBS is a technology for transmitting data from one data source to multiple targets. MBS can improve the utilization rate of network resources, especially air interface resources. With the application and promotion of multimedia sharing services, efficient transmission of multicast and broadcast services has become particularly important for the next generation broadband mobile communication system. [0003] MBS based on WiMAX supports two access modes: single base station access and multiple base station access. In the multi-base station access mode, the concept of ...
