In addition, features described with reference to certain examples may be combined in other examples.

Non-independent working cells (NSA cells) exist in the 5G network, the cells do not broadcast SIB1 system messages, and therefore the UE cannot directly acquire scheduling information of other SIBs (such as SIB 2/3/4) through the cells. This type of Cell may be configured as a Secondary serving Cell (SCell) to the UE. For the connected UE, the scheduling information of other SIBs of the Cell is signaled to the UE through Radio Resource Control (RRC) signaling of a main Cell (e.g., Primary Cell (Pcell)) of the UE. For the non-connected UE, because it is not in the RRC connected state, it does not have the main control cell to which it belongs, and thus cannot acquire the scheduling information of other SIBs of the NSA cell and the information carried by the other SIBs.

When the NSA cell provides the MBMS, according to the current protocol, the non-connected UE cannot acquire the configuration information about the MBMS on the cell, and thus cannot receive the MBMS that may be interested in through the cell.

In order to solve the above problem, embodiments of the present invention provide a method, an apparatus, and a communication device for acquiring MBMS configuration information, so that a non-connected UE can correctly receive an MBMS from an NSA cell.

The method for acquiring the MBMS configuration Information according to the present invention is further described below with reference to specific embodiments, taking the first message as a Master Information Block (MIB) and the second message as an SIB.

Example one

In this embodiment, the MIB is used to indicate whether the dependent operating cell provides the MBMS configuration information.

A legacy MIB (legacy) in a New Radio (NR) has reserved bits, and in order to enable an NSA cell to provide MBMS configuration information, a predefined reception pattern may be associated with the reserved bits, and information related to MBMS configuration may be acquired through the predefined reception pattern.

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

For legacy UEs, when receiving the MIB provided by the NSA Cell, the UE does not read the reserved bit, and the UE considers the bit to be a reserved bit;

for the MBMS capable UE, i.e. the UE with MBMS capability, the UE reads the bit. When the UE reads that the bit value is "0", it can know that the NSA cell does not provide the MBMS, and when the UE reads that the bit value is "1", it can know that the NSA cell provides the MBMS.

For an NSA MBMS cell (namely, an NSA cell providing the MBMS), the MBMS capable UE determines whether the configuration information of the MBMS needs to be acquired through a predefined receiving pattern associated with the MBMS according to the value of a reserved bit. The predefined reception patterns may be one or more, and when one reception pattern is predefined, the UE determines to acquire configuration information of the MBMS through the reception pattern; when a plurality of receiving patterns are predefined, the UE can select the receiving patterns according to its own characteristics, and after the MBMS capable UE determines the receiving patterns, the MBMS configuration information is acquired through the receiving patterns, and the acquiring method may be any one of the following:

acquiring MBMS dedicated SIB1 information, such as SIBbis _ MBMS, through the reception pattern, where the system message may only carry scheduling information of a system message (such as newly introduced SIB10) carrying MBMS configuration information, and by reading the scheduling information in the SIBbis _ MBMS, it may know a reception manner of the system message (such as SIB10) acquiring the MBMS configuration information;

acquiring a system message carrying MBMS configuration through the receiving pattern, such as SIB 13, and acquiring configuration information of MBMS through receiving the system message.

Example two

In this embodiment, the MBMS configuration information is provided by a dedicated system message.

The legacy MIB is left with only one reserved bit, which the NSA Cell may not use for MBMS for subsequent extension. In order for the NSA Cell to be able to provide MBMS related configuration, a 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 primary system information dedicated to MBMS, such as MIBbis MBMS. Wherein the indication information may be provided by a physical layer and may be determined based on a combination of one or more of the following:

receiving a primary system message at an MBMS dedicated time synchronization block, determining that the cell provides an MBMS dedicated primary system message;

a primary system message is received on an MBMS dedicated PBCH channel, and it is determined that the message provides an MBMS dedicated primary system message.

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

receiving the MBMS-specific MIB at a predefined resource location;

and reading the MBMS special MIB to acquire the configuration information related to the MBMS on the cell.

The method for acquiring the configuration information about the MBMS in the cell includes any one of the following:

the configuration information of the MBMS is carried by SIB, such as newly introduced SIB10, the scheduling information of the SIB is carried by MBMS dedicated SIB1, and the MBMS dedicated MIB carries the resource location information of the MBMS dedicated SIB 1;

the configuration information of the MBMS is carried by SIB, such as newly introduced SIB10, and the MBMS-specific MIB carries the scheduling information of the SIB;

EXAMPLE III

In this embodiment, information of the NSA MBMS cell is provided through an SA cell (independently operating cell).

In a specific example, the SA cell provides information about MBMS of neighboring cells, wherein the MBMS information includes one or more of the following combinations:

indication information indicating whether a certain neighbor cell is an NSA MBMS cell;

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

When the MBMS capable UE knows that a certain adjacent cell is an NSA MBMS cell, the MBMS configuration information on the NSA MBMS cell is obtained through a predefined receiving pattern. The obtaining method may be any one of the following methods:

acquiring MBMS dedicated SIB1 information, such as SIBbis _ MBMS, through the reception pattern, the system message may only carry scheduling information of a system message (such as newly introduced SIB10) carrying MBMS configuration information, and by reading the scheduling information in the SIBbis _ MBMS, it may know a reception manner of the system message (such as SIB10) acquiring the MBMS configuration information;

and acquiring a system message carrying the MBMS configuration through the receiving pattern, such as SIB 13, and acquiring the configuration information of the MBMS through receiving the system message.

In another specific example, the SA cell provides information of neighboring cells about MBMS, wherein the MBMS information includes one or more of the following:

an MBMS list provided by an MBMS cell of a certain adjacent cell;

resource location information of MBMS-dedicated SIB1 of a certain NSA cell;

and the offset value of the system frame and/or subframe and/or time slot of the SA cell and a certain NAS MBMS cell.

When the system frames of the SA cell and the NSA MBMS cell are completely aligned, the offset value may not be carried in the MBMS information.

The resource location information of the MBMS dedicated SIB1 of the NSA cell may be a resource location provided based on a radio system frame of the SA cell, and at this time, if the radio system frames of the SA cell and the MBMS cell are not aligned, the offset value needs to be provided; the resource location information may also be provided based on the radio system frame of the MBMS cell, and the offset value need not be provided.

When the MBMS capable UE knows that a certain adjacent cell is an NSA MBMS cell, acquiring an MBMS special SIB1 through the resource location information of the MBMS special SIB1 provided by the SA cell. The MBMS dedicated SIB1 may only carry scheduling information of a system message carrying MBMS configuration, and the MBMS capable UE receives the system message carrying MBMS configuration through the scheduling information in the MBMS dedicated SIB1, thereby acquiring MBMS configuration information on a corresponding NSA cell.

In another specific example, the SA cell provides information of a neighboring cell about MBMS, wherein the MBMS information includes one or more of the following combinations:

an MBMS list provided by an MBMS cell of a certain adjacent cell;

configuration information on MBMS control information on a certain neighbor cell; the configuration information may be a resource location where the NSA MBMS cell transmits MBMS control information;

configuration information on a certain neighbor cell about MBMS control information change;

deviation of system frame and/or subframe and/or time slot of the SA cell and a certain NAS MBMS cell.

When the system frames of the SA cell and the NSA MBMS cell are completely aligned, the offset value may not be carried.

The configuration information of the MBMS control information and the configuration information of the MBMS control information change may be resource locations provided based on a radio system frame of an SA cell, and at this time, if the radio system frames of the SA cell and the MBMS cell are not aligned, the offset value needs to be provided; the resource location information may also be provided based on the radio system frame of the MBMS cell, and the offset value need not 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 occurs, and when the value is "1", it indicates that a change occurs, and at this time, the MBMS capable UE receives the changed MBMS control information at the sending position of the MBMS control information; the configuration information of the MBMS control information change may be a resource location where the NSA MBMS cell issues the MBMS control information change, the UE may detect whether the MBMS control information change occurs at the corresponding resource location, and when the MBMS control information change occurs, the UE receives the changed MBMS control information at a sending location of the MBMS control information.

When the MBMS capable UE acquires that a certain adjacent cell is an NSA MBMS cell, the MBMS configuration information is received at a specific resource position based on the configuration information of the MBMS control information on the NSA MBMS cell acquired from the SA cell.

Example four

In this embodiment, the NSA MBMS cell provides legacy MIB and SIB1, and distinguishes legacy UE and MBMS capable UE knowing that the cell is an NSA MBMS cell by prohibiting the camping indication.

In a specific example, the NSA MBMS cell provides legacy MIB and legacy SIB 1. Wherein, the legacy MIB carries indication information (e.g. cellbar ═ true) for prohibiting residence. The legacy SIB1 may carry only scheduling information for MBMS-related system messages.

When the UE receives the MIB message from the NSA MBMS cell, the UE behaves as follows:

when reading the instruction information of prohibiting to reside carried in the MIB, Legacy UE considers that the cell is forbidden, and UE will no longer try to receive Legacy SIB1 through the resource location information of Legacy SIB1 carried in the MIB;

if the MBMS capable UE knows that the cell is an NSA MBMS cell, when it reads the camping prohibition indication information carried in the MIB, the cell is considered to be forbidden, but the UE will try to receive legacy SIB1 through the resource location information of legacy SIB1 carried in MIB;

if the MBMS capable UE does not know that the cell is an NSA MBMS cell, when it reads the indication information of prohibiting camping carried in the MIB, the UE considers that the cell is forbidden, and the UE will not try to receive the legacy SIB1 through the resource location information of the legacy SIB1 carried in MIB.

The MBMS capable UE knows whether a cell is an NSA MBMS cell by the following means:

obtaining whether a cell is an NSA MBMS cell or not through the indication information of the adjacent cell, such as SA cell indication;

whether a certain cell is an NSA cell is known through indication information carried by an MIB in an NSA MBMS, for example, whether a certain cell is an NSA cell is indicated by using a reserved bit in a legacy MIB.

In another specific example, the NSA MBMS cell provides legacy MIB and legacy SIB 1. Wherein, legacy SIB1 carries indication information (e.g. cellreserved for other use) ("true") for prohibiting camping, and may only carry scheduling information of the system message related to the MBMS.

And when the UE receives the MIB message from the NSA MBMS cell, receiving the legacy SIB1 according to the resource location information of the legacy SIB1 carried in the MIB. When receiving SIB1, the UE behaves as follows:
