In addition, a plurality of system combinations (e.g., LTE or a combination of LTE-a and 5G, etc.) may be applied.

In some embodiments, a new terminal type is proposed called a reduced capability UE (Reduced capability UE) or 5G power save (NR-lite) terminal or a Redcap terminal. The terminal is similar to the Internet of things equipment in LTE; terminals of this type are generally required to meet the requirements of at least one of: low cost and low complexity; a degree of coverage enhancement; power saving; some of the terminals are 1 receiving antenna (1 RX) or some of the terminals are 2 receiving antennas (2 RX); and R18, the bandwidth is further reduced after the Redcap termination is introduced.

In some embodiments, after the introduction of the Redcap terminal, the system information block (SystemInformationBlock, SIB) may be for the Redcap terminal; for example, an uplink or downlink initial BWP is configured in SIB1 alone. Typically, the terminal will configure uplink or downlink initial BWP for the Redcap terminal alone using SIB1 preferentially. And only if the network does not have an uplink or downlink initial BWP configured as a Redcap terminal alone, the uplink or downlink initial BWP with the legacy terminal is used.

Illustratively, regarding the downstream initiation BWP (initialDownlinkBWP) where the Redcap terminal is configured separately, several provisions are as follows:

if there is a separately configured downlink initial BWP, the Redcap terminal uses the downlink initial BWP instead of the conventional downlink initial BWP. If the separately configured downlink initial BWP location and bandwidth (locationband) field contains the entire control resource set (CORESET # 0), the terminal applies the location and bandwidth (e.g., determines a frequency location of a signal described with respect to the location and bandwidth) upon receiving the field; but the separately configured downlink initial BWP maintains the control resource set (CORESET # 0) until after receiving RRC establishment or RRC recovery or RRC reestablishment. Otherwise, if the location and bandwidth of the separately configured downlink initial BWP does not contain the entire control resource set (CORESET # 0), the terminal receives the DL message using the separately configured downlink initial BWP during and after the initial access (e.g., msg2, msgB, or Msg 4).

If there is no separately configured downstream initial BPW, the Redcap terminal uses the conventional downstream initial BWP, provided that it does not exceed the Redcap terminal maximum bandwidth.

It can be seen that: when the bandwidth of the initial BWP includes the entire CORESET #0, the terminal will use the initial BWP after entering the reception of the RRC message, and will use CORESET #0 before receiving the RRC message. And if the bandwidth of the initial BWP does not include the entire CORESET #0, the terminal uses the initial BWP for message reception (Msg 2, msgB or Msg 4) in the random access procedure.

In some embodiments, common frequency resources (common frequency resource, CFR) are introduced. A separate CFR may be introduced that may be used when the configuration bandwidth of the default CFR in SIB20 exceeds the bandwidth capabilities of the bandwidth limited terminal.

Illustratively, the Redcap terminal introduces a separate CFR configuration in SIB20 than the normal terminal; the details are shown in table 1 below.

Namely, CFR configuration for MCCH and MTCH reception is introduced for the Redcap terminal; if this field does not exist, the terminal may be using the CFR of the normal terminal, which is configured exactly in the frequency range of the Redcap terminal.

in some embodiments, a way is protected in which a network configuration configures MBS parameters for a particular type of terminal.

Optionally, the specific type of terminal is the first type of terminal in the previous embodiment; the manner of configuring MBS parameters may be to configure the first configuration in the previous embodiment.

Alternatively, the bandwidth supported by the specific type of terminal is limited compared to the bandwidth supported by the general terminal. The normal terminal may be the second type of terminal in the previous embodiment.

Alternatively, the specific type of terminal may be a Redcap terminal or a subsequently enhanced eRedcap terminal.

In some embodiments, for a specific type of terminal, if its specific downlink initial BWP (such as the initial downlink BWP-Redcap in the previous embodiment) does not include a CD-SSB or does not associate a CD-SSB, the method may also be used for MBS monitoring.

Alternatively, the specific downlink initial BWP may be the initial BWP of the previous embodiment.

Optionally, the specific downlink initial BWP may include a search space MCCH and/or a search space MTCH. It will be appreciated that the precondition for the configuration of the search space MCCH and/or search space MTCH is that the downlink initial BWP comprises a CD-SSB and an entire set of control resources (CORESET # 0). That is, in the embodiment of the present disclosure, whether the downlink initial BWP includes the CD-SSB or whether the downlink initial BWP is associated with the CD-SSB is not limited, so that the MBS monitoring can be implemented.

In some embodiments, for a particular downlink initial BWP (such as the initial downlink BWP-Redcap in the previous embodiments) that does not contain a CD-SSB or is not associated with a CD-SSB, then the NCD-SSB or the associated NCD-SSB may be configured for terminal-assisted listening to the MBS. At this time, MBS service listening may be normally performed on the specific downlink initial BWP.

Optionally, the specific downlink initial BWP may perform MBS synchronization, MBS measurement, channel estimation, and/or the like for MBS listening.

In some embodiments, the network device configures the NCD-SSB or associated NCD-SSB for the terminal to notify the terminal in a broadcast message when the terminal assists in listening to the MBS.

In some embodiments, the network device configures the NCD-SSB or associated NCD-SSB for terminal assisted MBS listening, the terminal may be notified in a dedicated message.

Optionally, the network device notifies the terminal in an RRC release message.

Optionally, the network device informs the terminal about to enter the inactive state in an RRC release message informing it of the NCD-SSB configuration. Exemplary NCD-SSB configurations can be found in Table 3 below.

In some embodiments, when the network device configures the NCD-SSB for terminal-assisted MBS monitoring, the NCD-SSB that originally continued to be used for other purposes may also be utilized; if the terminal can use NCD-SSB to synchronize and measure SDT transmission, the SDT can be used as MBS synchronization and measurement.

Optionally, one NCD-SSB included in the specific downlink initial BWP is used for one purpose.

In some embodiments, new terminal capabilities are introduced, i.e. the new terminal capabilities are used to indicate whether the terminal has the capability to receive MBS with NCD-SSB. That is, MBS listening is supported on the Redcap-specific initial DL BWP associated with NCD-SSB.

Alternatively, the new terminal capability may be the capability indicated in the capability information in the previous embodiment.

Optionally, the terminal determines the capability information and/or the terminal reports the capability information to the network device.
