All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

1 is a flowchart of a first embodiment of a resource allocation method according to the present invention. In this embodiment, a UE is used as an execution entity as an example. As shown in FIG. 1 , the method in this embodiment may include:

S101. The UE acquires an MBSFN area configuration message sent by the network side device, where the MBSFN area configuration message includes an MBSFN subframe configuration and a physical multicast channel information table.

The network side device may be a base station, a multicast control entity, or the like, and the broadcast message sent by the network side device includes an MBSFN area configuration message.

The MBSFN subframe configuration includes a physical resource block group allocated to the MBSFN area corresponding to each subframe in the first subframe allocation information and the first subframe allocation information, where the physical multicast channel information table includes the second subframe allocation information. And a physical resource block group allocated to the physical multicast channel corresponding to each of the second subframe allocation information. The subframe allocated in the second subframe allocation information is also included in the subframe allocated by the first subframe allocation information, that is, the subframe allocated to the physical multicast channel information table is from the subframe allocated to the MBSFN region. Selected subset. The physical resource block group allocated to the physical multicast channel information table corresponding to the subframe in the second subframe allocation information, and the physical resource block group allocated to the MBSFN area corresponding to the subframe in the first subframe allocation information in. That is, the physical resource block group allocated to the physical multicast channel information table is from the subframe to which it belongs. The selected subset of the physical resource block groups assigned to the MBSFN area.

For example, in an MBSFN subframe configuration period, the first subframe allocation information is the first and second physical resource block groups of the first subframe, and the third and fourth physical resource block groups of the third subframe, The subframe to which the second subframe allocation information can be allocated may be selected from the first subframe and the third subframe, and if the selected first subframe, the physical resource block group in the second subframe allocation information can only be from the first subframe. Select from 2 physical resource block groups.

The physical resource block group is a continuous N physical resource block, where N is a parameter carried in the MBSFN subframe configuration, or N is a parameter carried in a notification message broadcasted by the network side device, or N is a preset parameter.

S102. The UE receives the MTCH according to the MBSFN area configuration message.

Specifically, before the receiving, by the S102 UE, the MTCH according to the MBSFN area configuration message, the method further includes:

The UE receives the MSI according to the MBSFN area configuration message.

At this time, the UE receives the MTCH according to the MBSFN area configuration message and the MSI.

In the embodiment of the present invention, as a first implementation manner, resources of one physical multicast channel are allocated based on MSI among multiple sessions, but an MSI period is less than 80 ms, and the MSI includes each of physical multicast channels. The logical channel number of the session is allocated to the physical resource block group corresponding to the logical channel number, and the physical resource block group allocation is allocated by using a bitmap. For example, each bit corresponds to a physical resource block group allocated to the physical multicast channel in the MSI scheduling period, the first bit corresponds to the first physical resource block group, and the physical resource block groups of different subframes are arranged in the order of the subframe. For example, the resource allocation corresponding to the logical channel number LCID1 is "10101010", the resource allocation corresponding to LCID2 is "01000100", and the resource allocation corresponding to LCID3 is "00010001". It can also be assigned to the physical multiple in each corresponding MSI scheduling period. The subframe of the broadcast channel. In this way, the time interval of the physical resource block group assigned to the session corresponding to one LCID can be reduced, so that the session can carry services that are more sensitive to delay requirements. For example, VoIP services can also reduce the resources allocated to a session corresponding to an LCID, so that the session can efficiently carry lower-rate services.

As a second implementation manner, the period of the MSI is not shortened and is still 80 ms. The transmission delay is reduced by allocating resources for a certain logical channel in an MSI period, and the MSI includes a physical multicast channel. The logical channel number of each session in the corresponding channel number The physical resource block group is allocated, and the same logical channel number in one MSI period corresponds to a plurality of allocated physical resource block groups. That is, the same session is scheduled multiple times in one MSI period. In this way, the time interval of resources allocated to a session corresponding to one LCID can be reduced, so that the session can carry services that are more sensitive to delay requirements. It is also possible to reduce the resources allocated to a session corresponding to one LCID, so that the session can efficiently carry lower-rate services.

As a third implementation manner, the resources of one physical multicast channel are not based on the MSI, but are based on the session configuration, and specifically: the physical multicast channel information table further includes The physical resource block group allocated to the session corresponding to each of the three subframe allocation information and the third subframe allocation information. That is, which physical resource block groups indicating which subframes of the physical multicast channel are allocated to the session. The subframe allocated in the third subframe allocation information is also included in the subframe allocated by the second subframe allocation information. That is, the subframe allocated to the session is a subset selected from the subframes allocated to the physical multicast channel information table.

The logical channel number of each session is allocated to the physical resource block group corresponding to the logical channel number, and the same logical channel number in one MSI period corresponds to a plurality of allocated physical resource block groups. That is, the same session is scheduled multiple times in one MSI period. And the multicast broadcast service scheduling information message sent by the multicast control unit (MCE) to the base station is carried Based on the service type, the base station identifies that the service needs to allocate resources multiple times on a certain logical channel based on the service type.

That is, the physical resource block group allocated to the session is a selected subset of the physical resource block groups allocated to the physical multicast channel information table from the subframe to which it belongs. For example: in a physical multicast channel information table resource allocation period, the second subframe allocation information is the first and second physical resource block groups of the first subframe, and the third and fourth physical resources of the third subframe. The block group, the subframe to which the third subframe allocation information can be allocated may be selected from the first and third subframes, and if the selected first subframe, the physical resource block group in the third subframe allocation information can only Select from the first and second physical resource block groups.
