Embodiment 1
[0063] It is assumed that the cells in this area are all in FDD mode.
[0064] The resources for transmitting MBMS services in multiple cells are configured by the MCE (one MCE can configure many cells), and the selectable subframes are #1, #2, #3, #6, #7, #8. The resources for transmitting MBMS services in a single cell are configured by the base station, and the selectable or preferential subframes are #5, #0, #4, and #9. How to use subframes #5, #0, #4, and #9 is described as follows:
[0065] If the MBMS service volume transmitted by a single cell is small, that is, when the MBMS service volume can be carried by the #5 subframe, only the #5 subframe is configured for the single cell transmission of the MBMS service, because subframe #5 has With more resources, compared with #4, #9 is much less likely to be configured as paging subframes (subframes #0 and #5 are less likely to be configured as paging subframes). As the MBMS service volume of a single cell increases, the #...
Embodiment 2
[0070] It is assumed that the cells in this area are all in TDD mode.
[0071]Since the TDD mode of LTE has 7 configurations of uplink and downlink subframes with different proportions, as shown in Table 3, the subframes for multi-cell transmission of MBMS services specified in LTE are except for subframes #0, #1, #5, # Non-uplink subframes other than 6.
[0072] Table 3 LTE uplink and downlink subframe configuration table
[0073]
[0074] In Table 3, D represents a downlink subframe, U represents an uplink subframe, and S represents a switching subframe from downlink to uplink.
[0075] The resources for transmitting MBMS services in multiple cells are configured by the MCE (one MCE can configure many cells), and the selectable subframes are non-uplink subframes except subframes #0, #1, #5, and #6. The resources for transmitting MBMS services in a single cell are configured by the base station, and the selectable or preferential subframes are #0, #5, #1, a...
