Definitions
- the present invention relates to a wireless communication network, and more particularly to a communication method and apparatus for broadcasting and/or multicasting in a wireless network.
- Enhanced Multimedia Broadcast Multicast Service eMBMS
- MBSFN Multimedia Broadcast Multicast Service Single Frequency Network
- the MBMS services are simultaneously transmitted by using the same time-frequency resources, so that the signals of the MBMS services of the respective cells can be naturally superimposed on each other in the air, and the radio frequency (RF) combining gain is provided to the user equipment, so that the MBMS service data is received and extracted.
- RF radio frequency
- Different MBMS services with the same QoS can be statistically multiplexed (SM) and transmitted in the same MCH (multicast channel). These services that can be statistically multiplexed are defined as a "Service Bundle".
- a single, non-statistically multiplexed service can be thought of as a single business package containing only one service. In the scheduling process, a business package can be regarded as a business.
- MCE Multicast Coordination Entity
- MSP multicast channel allocation scheme
- MCS transmission priority and coding and modulation scheme
- the number of subframes actually occupied by the service may be smaller than the number of subframes allocated by the MCE and reserved in the MSAP. Therefore, in order to make better use of what is not actually occupied Sub-frames, to improve resource utilization, in contrast to the aforementioned MCE for semi-static subframe allocation, the wireless system also relies on the real-time fluctuation of the data volume of the eMBMS service data, for example, 320 ms as a scheduling period, for each period of time
- the amount of resources used for data transmission, that is, the number of subframes is dynamically and MAC layer-scheduled.
- the granularity of scheduling is in units of subframes. This real-time processing can be done by MAC dynamic scheduling in each scheduling cycle.
- each service in statistical multiplexing is continuously transmitted. Padding is only appended to the last subframe of each MCH in the scheduling period. The remaining subframes that are discovered after scheduling and are not occupied by the actual transmission of the MBMS service can be used for other services such as unicast.
- Figure 1 shows an example of MBMS dynamic scheduling based on MSAP.
- the standard specifies that subframes 0, 4, 5, and 9 cannot be defined as MBSFN.
- MBSFN Multicast broadcast single frequency network
- the wireless system determines the MBSFN transmission subframe allocation as subframes 1, 2, and 3 of each frame; and, the wireless system determines each scheduling period.
- the first ten frames can be used to carry MBSFN transmission subframes.
- the total number of subframes available for MCE for semi-static allocation is 30 in this 320ms scheduling period.
- the subframe occupied by the MSAP starts from the first frame and sequentially occupies MBSFN subframes in consecutive frames.
- a statistical multiplexing consists of three services SI, S2 and S3, which form a service package ⁇ SI, S2, S3 ⁇ .
- the MCE calculates 8 subframes for transmitting the three services, as shown in FIG. 1, namely, the first radio frame and the second radio frame, the first, second, and third. Subframe, the first and second subframes of the third radio frame.
- the MCE reserves the allocation result in the MSAP and provides it to each base station and mobile terminal.
- the base station may leave a subframe that is not actually occupied, as shown by the horizontal block in FIG.
- the base station can allocate the subframe to services such as unicast. Padding is only appended to the last subframe of each MCH in the scheduling period, as shown by the vertical block in Figure 1.
- MBMS dynamic scheduling has lower real-time requirements than unicast scheduling. Therefore, for the Physical Multicast Channel (PMCH), there is no dedicated downlink control channel such as the Physical Downlink Control Channel (PDCCH) corresponding to the Physical Downlink Shared Channel (PDSCH), so how to set the MBMS for each scheduling period
- PMCH Physical Multicast Channel
- PDCCH Physical Downlink Control Channel
- PDSCH Physical Downlink Shared Channel
