Example 1

In this embodiment, whether the non-independent working cell provides MBMS configuration information is indicated through the MIB.

The legacy MIB in the New Radio (NR) has reserved bits. In order to enable the NSA cell to provide MBMS configuration information, a predefined receiving pattern can be associated with the reserved bits. The pattern can obtain information related to the MBMS configuration.

In a specific example, when the value of the reserved bit is "0", it means that the cell that provides the MIB received by the current UE does not provide MBMS configuration information, that is, does not provide MBMS; when the value of the reserved bit is "0" 1", it means that the cell receiving the current MIB provides MBMS configuration information, that is, provides MBMS.

For legacy UEs, when receiving the MIB provided by the NSA Cell, the above reserved bits are not read, and this type of UE considers this bit to be a reserved bit;

For an MBMS capable UE, that is, an MBMS capable UE, the UE will read the above bits. When the UE reads that the bit value is "0", it can know that the NSA cell does not provide MBMS. When the UE reads that the bit value is "1", it can know that the NSA cell is providing MBMS. MBMS.

For an NSA MBMS cell (that is, an NSA cell that provides MBMS), the MBMS capable UE determines, according to the value of the reserved bit, whether it needs to acquire the configuration information of the MBMS through a predefined reception pattern associated therewith. There can be one or more predefined receiving patterns. When one receiving pattern is predefined, the UE determines to obtain the MBMS configuration information through the receiving pattern; when multiple receiving patterns are predefined, the UE can select the receiving pattern according to its own characteristics. pattern, after the MBMS capable UE determines the receiving pattern, it obtains the configuration information of the MBMS through the receiving pattern, and the obtaining method can be any of the following:

Obtain MBMS-specific SIB1 information, such as SIBbis_MBMS, through the receiving pattern.

By reading the scheduling information in SIBbis_MBMS, you can know the obtained The receiving method of system messages (such as SIB10) carrying MBMS configuration information;

The system message carrying the MBMS configuration is acquired through the receiving pattern, such as the SIB 13, and the configuration information of the MBMS is acquired by receiving the system message.

Embodiment 2

In this embodiment, the MBMS configuration information is provided through dedicated system messages.

There is only one reserved bit left in the legacy MIB. To facilitate subsequent expansion, the NSA Cell may not use the reserved bit for MBMS. In order to enable the NSA Cell to provide MBMS related configuration, dedicated MIB and SIB1 need to be used for MBMS scheduling.

Specifically, the UE determines, based on the received indication information, that the cell provides MBMS-specific primary system information, such as MIBbis_MBMS. The indication information may be provided by the physical layer, and may be determined based on a combination of one or more of the following information:

Receive the primary system message on an MBMS-specific time synchronization block, and determine that the cell provides an MBMS-specific primary system message;

The main system message is received on an MBMS-dedicated PBCH channel, and it is determined that the message provides an MBMS-dedicated main system message.

When receiving this indication, the MBMS capable UE behaves as follows:

Indication information indicating whether a neighbor cell is an NSA MBMS cell;

The MBMS list provided by the MBMS cell of a certain neighbor cell.

When the MBMS capable UE learns that a neighbor cell is an NSA MBMS cell, it acquires configuration information about MBMS on the NSA MBMS cell through a predefined reception pattern. The acquisition method can be any of the following:

Obtain MBMS-specific SIB1 information, such as SIBbis_MBMS, through the receiving pattern. The system message may only carry the scheduling information of the system message (such as the newly introduced SIB10) that carries the MBMS configuration information. By reading the scheduling information in SIBbis_MBMS, you can know the obtained The receiving method of system messages (such as SIB10) carrying MBMS configuration information;

The system message carrying the MBMS configuration is acquired through the receiving pattern, such as the SIB 13, and the configuration information of the MBMS is acquired by receiving the system message.

When the MBMS capable UE learns that a certain neighboring cell is an NSA MBMS cell, it acquires the MBMS dedicated SIB1 through the resource location information of the MBMS dedicated SIB1 provided by the SA cell. The MBMS dedicated SIB1 may only carry the scheduling information of the system message carrying the MBMS configuration, and the MBMS capable UE receives the system message carrying the MBMS configuration through the scheduling information in the MBMS dedicated SIB1, and then obtains the MBMS configuration information on the corresponding NSA cell .

At this time, if the radio system frames of the SA cell and the MBMS cell are not aligned, the The offset value may also be resource location information provided on the basis of the radio system frame of the MBMS cell, in which case the offset value does not need to be provided.

The configuration information of the MBMS control information change may be one-bit indication information, for example, when the value is "0", it indicates that no change has occurred, and when the value is "1", it indicates that the change has occurred, and the MBMS capable UE is in the The sending position of the MBMS control information receives the changed MBMS control information; the configuration information of the MBMS control information change may be the resource position where the MBMS control information is changed by the NSAMBMS cell, and the UE can detect whether the MBMS control occurs at the corresponding resource position Information change, when the MBMS control information is changed, the UE receives the changed MBMS control information at the sending position of the MBMS control information.

When the MBMS capable UE acquires that a certain neighboring cell is an NSA MBMS cell, it goes to a specific resource location to receive the MBMS configuration information based on the configuration information of the MBMS control information on the NSA MBMS cell acquired from the SA cell.
