In this step, the terminal may monitor the PEI on the additional initial BWP according to the first PEI configuration information.

In the PEI configuration method provided by the embodiment of the present application, the terminal obtains first PEI configuration information and performs PEI monitoring according to the first PEI configuration information, and the first PEI configuration information is used for PEI configuration on an additional initial BWP. The embodiment of the present application configures the corresponding PEI configuration information for the additional initial BWP, and improves communication performance such as PEI detection reception and paging reception for terminals that perform paging reception, initial access, and other processes on the additional initial BWP .

In one embodiment, the terminal may determine whether the DCI is the DCI carrying the PEI according to the RNTI of the scrambled DCI. For example, if the DCI is scrambled by the PEI-RNTI, the DCI carries the PEI. In addition, the first RNTI may also be a P-RNTI.

4) The first offset, the first offset includes: the starting moment of the radio frame (Frame) where the paging early indication opportunity (Paging Early Indication-Occasion, PEI-O) is located and the paging opportunity (Paging Occasion, PO) in at least one paging radio frame (Paging Frame, PF) The offset between the start moments of the earliest or latest PF in time, the PO is associated with the PEI-0.

7) The number of subgroups a PO contains.

8) The number of POs associated with a PEI-O. It can be understood that the number of POs associated with a PEI-O can be understood as the number of POs indicated by a PEI-O.

For one or more of the above 1) to 8), if not carried in the first PEI configuration information, the one or more items not carried in the first PEI configuration information can share the corresponding items in the second configuration information ; Wherein, the second PEI configuration information is used for PEI configuration on the initial BWP.

In each of the foregoing embodiments, if the first PEI configuration information does not include the first information, the method further includes: the terminal obtains the first information according to the second PEI configuration information; or, if the first PEI configuration information If the PEI configuration information does not include the first information, the first information adopts a default value configured on the network side or agreed by the protocol; wherein, the second PEI configuration information is used for PEI configuration on the initial BWP.

For example, if the above-mentioned item of configuration information about the first PEI is not configured by the network, the item of configuration information can be configured the same according to the corresponding item of the second PEI configuration information configured by the network side for the initial BWP, or It is configured using the default value specified by the protocol or the network configuration. The "some item" mentioned above may be any one or more of the above 1) to 8).

For example, if the above-mentioned first PEI configuration information does not include 7) the number of POs associated with one PEI-O, the terminal can assume that the number of POs associated with one PEI-O in the PEI configuration on the initial BWP is equal to the number of POs associated with one PEI-O used for additional The number of POs associated with a PEI-O on the initial BWP; or, the network configures a default value for the number of POs associated with a PEI-O, in the above cases, the number of POs associated with a PEI-O is equal to the default value .

Optionally, for the search space of the PEI mentioned in 1) above, the search space of the PEI is related to the common search space configured on the additional initial BWP.

Optionally, at least one of the above 1) to 8) can be shared with the corresponding item in the second configuration information (which can be understood as the same configuration) as stipulated in the network side configuration or agreement. Further, at least one item in the above 1) to 8) cannot be shared with the corresponding item in the second configuration information as stipulated in the configuration or protocol on the network side.

In an example, in the case where the first common search space (Common Search Space, CSS) is not configured on the additional initial BWP, the search space of the PEI is not the first common search space; wherein, the The first common search space includes at least one of the following a) to d):

a) System Information Block 1 public search space (System Information Block (SIB) 1 CSS).

b) Other system information block common search space (Other SIB CSS).

c) Paging Common Search Space (Paging CSS).

d) Random Access Common Search Space (Random Access (RA) CSS).

For example, in the case that Paging CSS is not configured on the additional initial BWP, the search space of the PEI cannot be configured as Paging CSS.

The aforementioned search space of the PEI is not the first common search space. Specifically, the search space of the PEI cannot reuse the first common search space, or the search space of the PEI cannot be configured as the first common search space. Specifically, for example, the search space index (ID) of the PEI is not equal to the first public search space ID.

In this embodiment, the first common search space may be configured on the additional initial BWP, and if the first common search space is not configured on the additional initial BWP, the search space of the PEI is not the first common search space. search space. In other embodiments, when the first common search space is configured on the additional initial BWP, the search space of the PEI may be the first common search space.

Optionally, for the CORESET of the PEI mentioned in 2) above, if the additional initial BWP does not contain a complete CORESET#0, the CORESET of the PEI is not CORESET#0, or in other words, the The CORESET of PEI cannot be configured as CORESET#0. It should be noted that not including the complete CORESET#0 includes not including CORESET#0.

Optionally, for the PEI CORESET mentioned in 2) above, the PEI CORESET is the public CORESET configured or included in the additional initial BWP. This embodiment considers that a public CORESET may be configured on the additional initial BWP, therefore, the CORESET of the PEI may be the public CORESET. The public CORESET may include a newly defined public CORESET in addition to the existing public CORESET, for example, the public CORESET associated with the additional initial BWP.

Optionally, for the first offset mentioned in 4) above, the first offset is related to at least one of the following a) and b).

a) Whether the additional initial BWP is configured or includes first content, the first content includes at least one of a first SSB and a paging search space (Paging CSS), and the first SSB may include a cell definition At least one of SSB (CD-SSB) and non-cell defined SSB (NCD-SSB).

b) The period of the first SSB; wherein, the first SSB includes at least one of CD-SSB and NCD-SSB.

In this embodiment, for example, if the additional initial BWP is not configured or does not include the first SSB, the value range of the first offset is the first range; if the additional initial BWP is not configured or does not include paging search space, the value range of the first offset is the second range; if the additional initial BWP is not configured or does not include the first SSB and paging search space, the value range of the first offset is the third scope. The reason for this configuration is that if the first SSB and/or paging CSS are not configured on the additional initial BWP, the terminal needs to jump to the initial BWP to receive the SSB before receiving the PEI, and then jump back to the additional initial BWP. The PEI is received on the initial BWP. If the PEI indicates that paging reception is required at this time, the terminal needs to jump to the initial BWP to perform the first SSB and paging reception. However, the aforementioned terminal needs a certain handover delay during the BWP handover process, so the first offset should at least ensure that it is greater than or equal to the handover delay.

In an embodiment, the correlation between the first offset and the first SSB period may be understood as the first offset is the period size of K first SSBs, where K is a positive integer.

Optionally, in the case where the first PEI configuration information includes the PEI search space mentioned in 2), the additional initial BWP includes a second SSB, where the second SSB includes a CD- At least one of SSB and NCD-SSB.

The first PEI configuration information mentioned in this embodiment includes the PEI search space may be understood as that the PEI search space is configured on the additional initial BWP. That is to say, in the case that the PEI search space is configured on the additional initial BWP, (the terminal expects) the additional initial BWP includes the second SSB.

Optionally, in the case that the additional initial BWP does not include CD-SSB and/or complete CORESET#0, the second SSB is NCD-SSB. That is to say, when the PEI search space is configured on the additional initial BWP and the additional initial BWP does not contain CD-SSB and/or complete CORESET#0, (the terminal expects) the additional The NCD-SSB is included on the initial BWP.

Optionally, when the second SSB is a CD-SSB, the additional initial BWP does not include NCD-SSB. That is to say, in the case where the PEI search space is configured on the additional initial BWP and the additional initial BWP includes the CD-SSB, the additional initial BWP does not include the NCD-SSB.

Optionally, in the foregoing multiple embodiments, when the first PEI configuration information includes the PEI search space, the additional initial BWP is configured with Paging CSS. That is to say, in the case where the search space of PEI is configured on the additional initial BWP, (the terminal expects) the additional initial BWP is also configured with Paging CSS, that is, the terminal does not expect the PEI SS that it needs to monitor It is configured on a different BWP from the Paging SS.

Optionally, the search space of the PEI that the terminal needs to monitor and detect and the paging CSS are configured on the additional initial BWP at the same time, or are configured on the initial BWP at the same time.

Optionally, for the size of the DCI bearing the PEI mentioned in 6) above, the size of the DCI bearing the PEI is less than or equal to the first DCI size, wherein the first DCI size consists of the following a) to c) determined by at least one of .

a) The bandwidth of CORESET#0 configured by the Master Information Block (MIB).

b) The bandwidth of the additional initial BWP.

c) The bandwidth of the common CORESET configured on the additional initial BWP.

For example, the size of the first DCI is determined by the maximum or minimum value among the above three items.

In an example, when the Paging CSS is configured on the additional initial BWP, the size of the first DCI is determined by the bandwidth of the additional initial BWP or the bandwidth of the common CORESET configured on the additional initial BWP.

In an example, when no Paging CSS is configured on the additional initial BWP, the size of the first DCI is determined by the bandwidth of CORESET#0 configured in the MIB.

Optionally, as mentioned in the foregoing embodiments, the first DCI may be a downlink fallback DCI (such as DCI 1-0), and the first DCI includes a paging DCI.

In order to describe in detail the method for configuring the PEI provided by the embodiment of the present application, the following description will be made in conjunction with several specific embodiments.

In this embodiment, the terminal (such as the redcap terminal) obtains the first PEI configuration information configured on the additional initial BWP by receiving system information on the initial BWP. In addition, the network configuration additional initial BWP includes non-cell defined SSB (NCD-SSB) and paging SS. Wherein, the first PEI configuration information may include at least one of the following:

1) PEI SS. In this embodiment, the network configures the PEI SS to reuse the paging SS that is also configured on the additional initial BWP. That is, the PEI SS is the paging SS, and the SS IDs of the two are the same and not 0.

2) CORESET of PEI. In this embodiment, the CORESET of the network configuration PEI is the public CORESET configured by the additional initial BWP, as shown in Figure 3, the frequency domain size of the PEI CORESET is equal to the frequency domain size of the public CORESET; wherein, the horizontal direction in Figure 3 represents the time domain direction , and the vertical direction represents the frequency domain direction.

3) First offset. As shown in Figure 3, considering the limited ability of the terminal to monitor and detect PEI and paging on the additional initial BWP, the value of the first offset is usually large enough, for example, to ensure that the first offset contains 4 NCD-SSB.

4) Second offset. As shown in Figure 3, it refers to the size of the beginning of the radio frame where the starting distance of the first physical downlink control channel (Physical Downlink Control Channel, PDCCH) monitoring opportunity of PEI-O is located.

5) PEI DCI size. Since the first DCI size (including paging DCI) configured on the additional initial BWP is determined according to the additional initial BWP, in order to ensure the detection performance of the PEI DCI, it is necessary to satisfy that the PEI DCI is smaller than the first DCI size. The first DCI is fallback DCI, the format is DCI 1-0, and is scrambled by P-RNTI.

6) The number of subgroups contained in a PO. Since the number of terminals to which the additional initial BWP is applied is large, the number of subgroups included in the PO may be greater than the number of subgroups included in the PO to which the initial BWP is applied.

7) The number of POs associated with a PEI-O. The number of POs associated with the PEI-O existing on the additional initial BWP may also be configured differently from the number of POs associated with the PEI-O existing on the initial BWP.

It should be noted that the PEI-O in FIG. 3 is associated with PO1 and PO2. FIG. 3 schematically shows a PO associated with a PEI-O. In fact, there may be more PEI-O and its Associated POs.

In this embodiment, the terminal may monitor the PEI on the additional initial BWP based on the first PEI configuration information.

In addition, in order to serve terminals that use the initial BWP for initial access (including PEI and paging receiving process), such as terminals with normal capabilities, the network will also configure the associated second PEI configuration information for the initial BWP.
