[0058] In the current 3GPP standardization, a new terminal type, i.e., a reduced capability (Redcap) type terminal, is proposed. For the Redcap type terminal, how to configure an initial BWP and which BWP should be switched to when the Redcap type terminal needs to perform BWP switching in a random access channel (RACH) process are still problems to be solved.

[0059] To this end, the present disclosure provides an initial BWP configuration method and device.

[0062] Figure 2 A flowchart of an initial BWP configuration method according to an embodiment of the present disclosure is shown. As shown in Figure 2 The method can be performed by a network device and includes the following steps.

[0063] S201, BWP related information is sent to a terminal, wherein the BWP related information includes first downlink initial BWP information indicating a downlink initial BWP dedicated to a reduced capability specific type terminal and / or first uplink initial BWP information indicating an uplink initial BWP dedicated to the specific type terminal.

[0064] In some embodiments, the specific type of terminal refers to a Redcap type terminal.

[0065] In some embodiments, the BWP related information is carried in a System Information Block Type 1 (SIB1).

[0066] As an implementation, an Information Element (IE) item, such as “DownlinkConfigCommonSIB-Redcap”, is added in the SIB1 for the specific type of terminal.

[0067] As an example, the Broadcast Control Channel (BCCH) configuration for the specific type of terminal can be the same as that for the regular type of terminal, thus there is no need to include a BCCH configuration field in the IE item. As another example, a BCCH configuration field can be included in the IE item to configure the BCCH separately for the specific type of terminal.

[0068] As an example, the Physical Control Channel (PCCH) configuration for the specific type of terminal can be the same as that for the regular type of terminal, thus there is no need to include a PCCH configuration field in the IE item. As another example, a PCCH configuration field can be included in the IE item to configure the PCCH separately for the specific type of terminal.

[0069] In some embodiments, when the first downlink initial BWP information indicating a downlink initial BWP dedicated for the specific type of terminal is included in the BWP related information, the first downlink initial BWP information can have at least one of the following search spaces: a Random Acess Response (RAR) search space, a paging search space, and other system message search space. As an example, the first downlink initial BWP information includes a Control Resource Set 0 (CORESET0), by which at least one of the RAR search space, the paging search space, and the other system message search space can be configured.

[0070] In some embodiments, when the first downlink initial BWP information indicating the downlink initial BWP dedicated to the terminal of a specific type is included in the BWP related information, the first downlink initial BWP information can have a RAR search space or a paging search space. As an example, the first downlink initial BWP information does not include a control resource set 0 (CORESET0) and only configures a RAR search space. As another example, the first downlink initial BWP information does not include a control resource set 0 (CORESET0) and only configures a paging search space.

[0071] In some embodiments, when the first downlink initial BWP information indicating the downlink initial BWP dedicated to the terminal of a specific type is included in the BWP related information, the first downlink initial BWP information can configure multiple downlink initial BWPs, which can have a RAR search space or a paging search space. For example, two downlink initial BWPs are configured, which contain a paging search space for the terminal of a specific type to listen to the paging message.

[0072] In some embodiments, when the first downlink initial BWP information indicating the downlink initial BWP dedicated to the terminal of a specific type and the first uplink initial BWP information indicating the uplink initial BWP dedicated to the terminal of a specific type are included in the BWP related information, for an asymmetric spectrum, the center frequency point of the uplink initial BWP indicated by the first uplink initial BWP information is aligned with the center frequency point of the downlink initial BWP indicated by the first downlink initial BWP information.

[0073] According to the initial BWP configuration method of the embodiments of the present disclosure, the network device sends the BWP related information indicating the downlink initial BWP and / or the uplink initial BWP of the terminal of a specific type to the terminal, so that the terminal of a specific type can determine the downlink initial BWP and the uplink initial BWP according to the BWP related information, thereby achieving the initial BWP configuration of the terminal of a specific type.

As shown in the figure, the method can be performed by a terminal of a specific type, which can refer to a Redcap type terminal, and the initial BWP configuration method can include the following steps. Figure 3

[0075] S301, obtaining the BWP related information sent by the network device, wherein the BWP related information includes the first downlink initial BWP information indicating the downlink initial BWP dedicated to the terminal of a specific type and / or the first uplink initial BWP information indicating the uplink initial BWP dedicated to the terminal of a specific type.

[0076] In some embodiments, the above step S301 includes obtaining the BWP related information from the SIB1.​

[0077] As an implementation, an Information Element (IE) item “DownlinkConfigCommonSIB-Redcap” for a specific type of terminal is included in SIB1.

[0078] As an example, a BCCH configuration field is included in the IE item, which is used to configure BCCH separately for the specific type of terminal. As another example, the BCCH configuration field is not included in the IE item, which indicates that the BCCH configuration for the specific type of terminal can be the same as that for the regular type of terminal, thus, the BCCH configuration for the regular type of terminal can be reused.

[0079] As an example, a PCCH configuration field is included in the IE item, which is used to configure PCCH separately for the specific type of terminal. As another example, the PCCH configuration field is not included in the IE item, which indicates that the PCCH configuration for the specific type of terminal can be the same as that for the regular type of terminal, thus, the PCCH configuration for the regular type of terminal can be reused.

[0080] In some embodiments, when the first downlink initial BWP information indicating the downlink initial BWP dedicated for the specific type of terminal is included in the BWP related information, the first downlink initial BWP information can have at least one of the following search spaces: RAR search space, paging search space, and other system message search space. As an example, the first downlink initial BWP information includes control resource set 0 (CORESET0), by which at least one of the RAR search space, the paging search space, and the other system message search space can be configured.

[0081] In some embodiments, when the first downlink initial BWP information indicating the downlink initial BWP dedicated for the specific type of terminal is included in the BWP related information, the first downlink initial BWP information can have the RAR search space or the paging search space. As an example, the first downlink initial BWP information does not include control resource set 0 (CORESET0), but only configures the RAR search space. As another example, the first downlink initial BWP information does not include control resource set 0 (CORESET0), but only configures the paging search space.

[0082] In some embodiments, when the BWP-related information includes first downlink initial BWP information indicating a downlink initial BWP dedicated to a specific type of terminal and first uplink initial BWP information indicating an uplink initial BWP dedicated to a specific type of terminal, for an asymmetric spectrum, the center frequency point of the uplink initial BWP indicated by the first uplink initial BWP information is aligned with the center frequency point of the downlink initial BWP indicated by the first downlink initial BWP information.

[0083] S302, determining the uplink initial BWP and the downlink initial BWP used by the specific type of terminal according to the BWP-related information.

[0084] After the specific type of terminal obtains the BWP-related information from the network device, the specific type of terminal can determine the uplink initial BWP and the downlink initial BWP used by the specific type of terminal according to the BWP-related information.

[0085] According to the initial BWP configuration method of the embodiments of the present disclosure, the network device sends the BWP-related information indicating the downlink initial BWP and / or the uplink initial BWP of the specific type of terminal to the terminal, so that the specific type of terminal can determine the downlink initial BWP and the uplink initial BWP according to the BWP-related information, thereby realizing the initial BWP configuration of the specific type of terminal.

[0092] If the BWP related information includes the first downlink initial BWP information indicating the downlink initial BWP dedicated to the specific type terminal, the specific type terminal can directly use the downlink initial BWP indicated by the first downlink initial BWP information as the downlink initial BWP used by the specific type terminal after obtaining the BWP related information.

[0094] If the BWP related information does not include the first downlink initial BWP information indicating the downlink initial BWP dedicated to the specific type terminal, the downlink initial BWP indicated by the BWP related information or the master information block (MIB) for the regular type terminal can be used as the downlink initial BWP used by the specific type terminal.

[0095] As an example, if the downlink initial BWP for the regular type terminal indicated in the BWP related information meets the bandwidth requirement of the specific type terminal, the downlink initial BWP for the regular type terminal can be used as the downlink initial BWP used by the specific type terminal.

[0096] As an example, if the downlink initial BWP for the regular type terminal indicated in the BWP related information does not meet the bandwidth requirement of the specific type terminal, the downlink initial BWP for the regular type terminal indicated in the MIB can be used as the downlink initial BWP used by the specific type terminal.

[0100] If the BWP related information does not include the first uplink initial BWP information indicating the downlink initial BWP dedicated to the specific type terminal, the uplink initial BWP for the regular type terminal indicated in the BWP related information can be used as the uplink initial BWP used by the specific type terminal.

The embodiment is based on Figure 6 The embodiment shown in the figure, the method can be performed by a specific type of terminal in a connected state, such as Figure 7 The initial BWP switching method can include the following steps.

[0115] S701, if there is no random access channel (RACH) on the currently activated BWP, the uplink BWP switching and the downlink BWP switching are performed according to the BWP related information obtained from the system information sent by the network device, wherein the system information includes master information block (MIB) and / or system information block type 1 (SIB1).

[0116] In some embodiments, the above step S701 includes any of the following steps.

[0117] When performing uplink BWP switching, the uplink BWP is switched to an uplink initial BWP with random access resources configured for the specific type of terminal. The following steps S7011-S7013 elaborate the details of uplink BWP switching, that is, the uplink BWP switching can be achieved by any of the following steps S7011-S7013.

[0118] S7011, when the BWP related information obtained from the SIB1 includes first uplink initial BWP information indicating an uplink initial BWP dedicated to the specific type of terminal, the uplink BWP is switched to the uplink initial BWP indicated by the first uplink initial BWP information.

[0119] In this embodiment, if the BWP-related information acquired from the SIB1 indicates an uplink initial BWP dedicated to the specific type of terminal, the specific type of terminal can directly switch the uplink BWP to the uplink initial BWP indicated by the BWP-related information dedicated to the specific type of terminal. In this embodiment, it is assumed that the BWP-related information acquired from the SIB1 indicates that the uplink initial BWP dedicated to the specific type of terminal has random access resources configured for the specific type of terminal.

[0120] S7012, when the BWP-related information acquired from the SIB1 includes first uplink initial BWP information indicating an uplink initial BWP dedicated to the specific type of terminal, and the uplink initial BWP indicated by the first uplink initial BWP information has random access resources configured for the specific type of terminal, switch the uplink BWP to the uplink initial BWP indicated by the first uplink initial BWP information.

[0121] When performing uplink BWP switching, the specific type of terminal can switch the uplink BWP to an uplink BWP having random access resources configured specifically for the specific type of terminal. Thus, if the BWP-related information acquired from the SIB1 indicates an uplink initial BWP dedicated to the specific type of terminal, it can be determined whether the uplink initial BWP indicated by the BWP-related information dedicated to the specific type of terminal has random access resources configured for the specific type of terminal, and if so, the specific type of terminal switches the uplink BWP to the uplink initial BWP indicated by the BWP-related information dedicated to the specific type of terminal.

[0122] In one embodiment, it is assumed that the network configures multiple uplink BWP having random access resources configured for the specific type of terminal, and the terminal can select one according to a rule. For example, one is randomly selected. If only one is configured, this one can be used.

[0123] S7013, when the BWP-related information acquired from the SIB1 includes second uplink initial BWP information indicating an uplink initial BWP for the regular type of terminal but does not include first uplink initial BWP information indicating an uplink initial BWP dedicated to the specific type of terminal, or when the BWP-related information acquired from the SIB1 includes the first uplink initial BWP information and the second uplink initial BWP information, but the uplink initial BWP indicated by the first uplink initial BWP information does not have random access resources configured for the specific type of terminal, switch the uplink BWP to the uplink initial BWP indicated by the first uplink initial BWP information.

[0124] In the present embodiment, if the BWP related information acquired from the SIB1 does not indicate the uplink initial BWP dedicated for the specific type of terminal but only indicates the uplink initial BWP for the regular type of terminal, the specific type of terminal can switch the uplink BWP to the uplink initial BWP for the regular type of terminal indicated by the BWP related information.

[0125] Alternatively, the specific type of terminal can switch the uplink BWP to the uplink BWP of the random access resource configured specifically for the specific type of terminal when performing the uplink BWP switching. In this way, if the BWP related information acquired from the SIB1 indicates both the uplink initial BWP for the regular type of terminal and the uplink initial BWP dedicated for the specific type of terminal, it can be determined whether the uplink initial BWP dedicated for the specific type of terminal indicated by the BWP related information has the random access resource configured for the specific type of terminal, and if not, the specific type of terminal switches the uplink BWP to the uplink initial BWP dedicated for the specific type of terminal indicated by the BWP related information.

[0126] Preferably, when performing the uplink BWP switching, if the BWP related information acquired from the SIB1 indicates the uplink initial BWP dedicated for the specific type of terminal, the specific type of terminal switches the uplink BWP to the uplink initial BWP dedicated for the specific type of terminal, otherwise, the specific type of terminal switches the uplink BWP to the uplink initial BWP for the regular type of terminal, and the pseudocode thereof is as follows:

[0127] For the specific type of terminal:

[0128] If the SIB1 indicates the uplink initial BWP for the specific type of terminal,

[0137] In one embodiment, assuming that the network configures multiple downlink initial BWPs with the RAR search space for the specific type of terminal, the terminal can select one according to the rule. For example, selecting the downlink initial BWP paired with the uplink initial BWP of the random access resource configured for the specific type of terminal. Assuming that only one is configured, this one can be used. As a preferred embodiment, if the network configures a separate uplink initial BWP for the specific type of terminal, and the random access resource is configured on it, the network will also configure a separate downlink initial BWP for the specific type of terminal, which contains the search space of the RAR.
