The embodiments described below are examples of apparatus and methods consistent with embodiments of the present disclosure, which are not to be interpreted as limiting the disclosure to the embodiments described herein. Rather, the following embodiments are provided as examples to illustrate the disclosure, in accordance with which many embodiments can be implemented.

[0072] In the related art, network equipment performs beamforming and beam scanning, which needs to rely on a beam mapping scheme, in which a mapping pattern between each beam and a time unit is indicated. In accordance with the beam mapping scheme, the network equipment also needs to configure corresponding time-frequency domain resources for each beam, so that the network equipment has corresponding time-frequency domain resources for information transmission when transmitting beams according to the beam mapping scheme, and the terminal equipment performs information reception based on the time-frequency domain resources and the corresponding beams.

[0073] In the embodiments of the present disclosure, one or more combinations of a narrowband synchronization signal, a narrowband physical broadcast information and a narrowband system information block are included in each group of downlink transmissions. Each group of downlink transmissions has corresponding time-frequency domain resources, and the network equipment can indicate the time-frequency domain resources to the terminal equipment by transmitting different groups of downlink transmissions, so that the terminal equipment uses the indicated time-frequency domain resources for downlink synchronization and / or broadcast information reception. The resource determination method, device and communication equipment provided by the present disclosure are described in detail below with reference to the accompanying drawings.

[0074] Figure 1 A flowchart of a resource determination method provided by the embodiments of the present disclosure is shown in FIG. 1. The method is applied to a terminal equipment.

[0075] As shown in FIG. 1, the method includes the following steps: Figure 1

[0076] Step 101, receiving a target downlink transmission transmitted by a network equipment.

[0077] The target downlink transmission is at least one group of one or more groups of downlink transmissions.

[0078] Each group of downlink transmissions can include one or more combinations of a narrowband synchronization signal, a narrowband physical broadcast information and a narrowband system information block. In some implementations, the narrowband synchronization signal can further include at least one of a narrowband primary synchronization signal and a narrowband secondary synchronization signal. Alternatively, in other implementations, the narrowband physical broadcast information is specifically a narrowband physical broadcast channel.

[0079] It should be noted that the above-mentioned implementations can be independently implemented or combined, and the present embodiment does not limit this.

[0080] The network equipment pre-configures multiple groups of downlink transmissions, and each group of downlink transmissions corresponds to a beam. At least one of the narrowband synchronization signal, the narrowband physical broadcast information and the narrowband system information block in different groups of downlink transmissions is different, so that different groups of downlink transmissions can be distinguished. The terminal equipment can determine the group to which the target downlink transmission belongs according to one or more of the narrowband synchronization signal, the narrowband physical broadcast information and the narrowband system information block included in the target downlink transmission. ​

[0081] In step 102, the corresponding time-frequency domain resource is determined according to the group to which the target downlink transmission belongs.

[0082] The time-frequency domain resource is used for downlink synchronization and / or broadcast information reception.

[0083] The network device sends the target downlink transmission to the terminal device, and the target downlink transmission includes one or more combinations of a narrowband synchronization signal, a narrowband physical broadcast information, and a narrowband system information block. The terminal device determines the group to which the target downlink transmission belongs according to at least one of the narrowband synchronization signal, the narrowband physical broadcast information, and the narrowband system information block included in the received target downlink transmission.

[0084] In some embodiments of the present disclosure, the network device has previously configured the terminal device with the corresponding time-frequency domain resource of each group, and the terminal device can determine the corresponding time-frequency domain resource according to the group to which the target downlink transmission belongs.

[0085] In another embodiment of the present disclosure, the corresponding time-frequency domain resource of each group has been specified based on a communication standard or the like, so that the terminal device can determine the corresponding time-frequency domain resource according to the group to which the target downlink transmission belongs.

[0086] After determining the corresponding time-frequency domain resource of the target downlink transmission, the terminal device can use the time-frequency domain resource for downlink synchronization and / or broadcast reception.

[0087] The target downlink transmission can be one group or multiple groups. The beams corresponding to the one or multiple groups of target downlink transmissions can be the same, and the time-frequency domain resources corresponding to the one or multiple groups of target downlink transmissions can be the same or different. Some scenarios will be described in detail below:

[0088] In one possible scenario, when the target downlink transmission corresponding to a beam is set to one group, the one group of target downlink transmissions corresponds to one or more time-frequency domain resources. The terminal device can use the one or more time-frequency domain resources corresponding to the one group of target downlink transmissions for downlink synchronization or broadcast information reception.

[0089] In another possible scenario, when the target downlink transmission corresponding to a beam is set to multiple groups, wherein the beam includes multiple beams, each group of target downlink transmissions corresponds to a different beam, and the multiple groups of target downlink transmissions can correspond to different one or more time-frequency domain resources, that is, each group of target downlink transmissions corresponds to different time-frequency domain resources, so that the terminal device can use the different one or more time-frequency domain resources corresponding to the multiple groups of target downlink transmissions for downlink synchronization or broadcast information reception.

[0090] It should be noted that the aforementioned set beam can be a beam through which the network device transmits the target downlink transmission, and of course, in some embodiments, the beam through which the network device transmits the target downlink transmission can be a beam corresponding to a group to which the target downlink transmission belongs, which is not limited in the embodiment. The terminal device can perform downlink synchronization and / or broadcast information reception according to the set beam and the determined time-frequency domain resource.

[0091] In the embodiment of the present disclosure, the network device transmits the target downlink transmission to the terminal device, and the terminal device determines the corresponding time-frequency domain resource according to the group to which the target downlink transmission belongs. Since the target downlink transmission is at least one of one or more groups of downlink transmissions, each group of downlink transmissions includes one or more combinations of a narrowband synchronization signal, a narrowband physical broadcast information, and a narrowband system information block. Each group of downlink transmissions has a corresponding time-frequency domain resource, and the network device can indicate the time-frequency domain resource to the terminal device by transmitting different groups of downlink transmissions, so that the terminal device uses the indicated time-frequency domain resource to perform downlink synchronization and / or broadcast information reception.

[0092] Figure 2 A flowchart of a resource determination method provided by the embodiment of the present disclosure is applied to a terminal device.

[0093] As shown in Figure 2 , the following steps are included:

[0094] Step 201, receiving a target downlink transmission transmitted by a network device.

[0095] The target downlink transmission is at least one of one or more groups of downlink transmissions, and each group of downlink transmissions includes one or more combinations of a narrowband synchronization signal, a narrowband physical broadcast information, and a narrowband system information block. The narrowband physical broadcast information is carried on a narrowband physical broadcast channel.

[0096] Each group of downlink transmissions can include one or more combinations of a narrowband synchronization signal, a narrowband physical broadcast information, and a narrowband system information block. In some implementations, the narrowband synchronization signal can further include at least one of a narrowband primary synchronization signal and a narrowband secondary synchronization signal. Alternatively, in other implementations, the narrowband physical broadcast information is specifically a narrowband physical broadcast channel.

[0097] It should be noted that the aforementioned implementations can be independently implemented or combined, which is not limited in the embodiment.

[0098] The network device is pre-configured with multiple groups of downlink transmissions, and each group of downlink transmissions corresponds to a beam. At least one of the narrowband synchronization signal, the narrowband physical broadcast information, and the narrowband system information block in different groups of downlink transmissions is different, so that the different groups of downlink transmissions can be distinguished. The terminal device can determine the group number of the group to which the target downlink transmission belongs according to one or more of the narrowband synchronization signal, the narrowband physical broadcast information, and the narrowband system information block contained in the target downlink transmission.

[0099] In step 202, the corresponding time-frequency domain resource is determined according to the group number of the group to which the target downlink transmission belongs.

[0100] In some embodiments, the group number of the group to which the target downlink transmission belongs is determined according to the first generation parameter of the narrowband secondary synchronization signal in the target downlink transmission and / or the base sequence of the narrowband secondary synchronization signal.

[0101] The base sequence of the narrowband secondary synchronization signal is generated according to the first generation parameter of the narrowband secondary synchronization signal. In some embodiments, the first generation parameter can be a cyclic shift parameter. As a possible implementation, each group of downlink transmissions has one or more corresponding cyclic shift parameters, and different groups of downlink transmissions have different cyclic shift parameters, so as to distinguish between different groups.

[0102] For example, each group of downlink transmissions can correspond to one to four cyclic shift parameters, and the cyclic shift parameter used by the narrowband secondary synchronization signal in the transmitted target downlink transmission can be one of the one or more cyclic shift parameters corresponding to the group to which the target downlink transmission belongs. The network device can select the corresponding cyclic shift parameter from the multiple cyclic shift parameters corresponding to the group to which the target downlink transmission belongs according to the time domain or frequency domain occupied by the transmitted target downlink transmission.

[0103] The network device substitutes the selected cyclic shift parameter into the base sequence generation formula of the narrowband secondary synchronization signal to obtain the base sequence of the narrowband secondary synchronization signal. In this embodiment, the generation formula of the base sequence can use the generation formula in the related protocol, or can be a formula corresponding to other generation rules preset in advance, which is not limited in this embodiment.

[0104] The terminal device generates each candidate base sequence according to the generation formula of the base sequence and the cyclic shift parameters corresponding to each group of downlink transmissions. The terminal device determines the base sequence of the narrowband secondary synchronization signal and the corresponding cyclic shift parameter in the target downlink transmission according to the correlation between each candidate base sequence and the narrowband secondary synchronization signal in the target downlink transmission, and further determines the group number of the group to which the target downlink transmission belongs according to at least one of the base sequence of the narrowband secondary synchronization signal and the corresponding cyclic shift parameter in the target downlink transmission.

[0105] In some embodiments, the group number of the group to which the target downlink transmission belongs is determined according to the second generation parameter of the narrowband physical broadcast channel in the target downlink transmission and / or the scrambling sequence of the narrowband physical broadcast channel.

[0106] The scrambling sequence of the narrowband physical broadcast channel is generated according to the second generation parameter of the narrowband physical broadcast channel. In some embodiments, the second generation parameter can be a scrambling initialization factor. As a possible implementation, in the multiple groups of downlink transmissions, each group of downlink transmissions has one or more corresponding scrambling initialization factors, and different groups of downlink transmissions have different scrambling initialization factors, so as to distinguish between different groups.

[0107] For example, the scrambling initialization factor corresponding to each group of downlink transmissions can be a scrambling initialization factor C set in the relevant protocol. init On this basis, different offsets are superimposed, or different coefficients are multiplied, or other rules are used to transform C init The scrambling initialization factors corresponding to different groups of downlink transmissions are different.

[0108] The network device substitutes the selected scrambling initialization factor into the scrambling sequence generation formula of the narrowband physical broadcast channel, so as to obtain the scrambling sequence of the narrowband physical broadcast channel. In this embodiment, the generation formula of the scrambling sequence can be the generation formula in the relevant protocol, or a formula corresponding to other generation rules preset in advance, which is not limited in this embodiment.

[0109] The terminal device generates each candidate scrambling sequence according to the generation formula of the scrambling sequence and the scrambling initialization factor corresponding to each group of downlink transmissions. The terminal device determines the scrambling sequence of the narrowband physical broadcast channel in the target downlink transmission and the corresponding scrambling initialization factor according to the correlation between each candidate scrambling sequence and the narrowband physical broadcast channel in the target downlink transmission, and further determines the group number of the group to which the target downlink transmission belongs according to at least one of the scrambling sequence of the narrowband physical broadcast channel in the target downlink transmission and the corresponding scrambling initialization factor.

[0110] In the embodiments of the present disclosure, the network device sends the target downlink transmission to the terminal device, and the terminal device determines the corresponding time-frequency domain resource according to the group to which the target downlink transmission belongs. Since the target downlink transmission is at least one of one or more groups of downlink transmissions, each group of downlink transmissions includes one or more combinations of a narrowband synchronization signal, a narrowband physical broadcast information and a narrowband system information block. Each group of downlink transmissions has corresponding time-frequency domain resources, and the network device can indicate the time-frequency domain resources to the terminal device by sending different groups of downlink transmissions, so that the terminal device uses the indicated time-frequency domain resources for downlink synchronization and / or broadcast information reception.

[0111] Figure 3 A flowchart of a resource determination method provided by an embodiment of the present disclosure is applied to a network device.

[0112] As shown in Figure 3 the following steps are included:

[0113] In step 301, a target downlink transmission is sent to a terminal device, wherein the target downlink transmission is at least one of one or more groups of downlink transmissions, each group of the downlink transmissions includes one or more combinations of a narrowband synchronization signal, a narrowband physical broadcast information, and a narrowband system information block, and each group of the downlink transmissions corresponds to a time-frequency domain resource.

[0114] The network device is preconfigured with a plurality of groups of downlink transmissions, and each group of the downlink transmissions corresponds to a beam. Each group of the downlink transmissions can include one or more combinations of a narrowband synchronization signal, a narrowband physical broadcast information, and a narrowband system information block. In some implementations, the narrowband synchronization signal can further include at least one of a narrowband primary synchronization signal and a narrowband secondary synchronization signal. Alternatively, in other implementations, the narrowband physical broadcast information is specifically a narrowband physical broadcast channel.

[0115] It should be noted that the foregoing implementations can be independently implemented or combined, and the present embodiment does not limit this.

[0116] The at least one of the narrowband synchronization signal, the narrowband physical broadcast information, and the narrowband system information block in different groups of downlink transmissions is different, so that different groups of downlink transmissions can be distinguished. The terminal device can determine the group to which the target downlink transmission belongs according to one or more of the narrowband synchronization signal, the narrowband physical broadcast information, and the narrowband system information block included in the target downlink transmission.

[0117] The network device sends the target downlink transmission to the terminal device, and the target downlink transmission includes one or more combinations of the narrowband synchronization signal, the narrowband physical broadcast information, and the narrowband system information block. The terminal device determines the group to which the target downlink transmission belongs according to at least one of the narrowband synchronization signal, the narrowband physical broadcast information, and the narrowband system information block included in the received target downlink transmission.

[0118] In some embodiments of the present disclosure, the network device has preconfigured the time-frequency domain resources corresponding to each group to the terminal device, and the terminal device can determine the corresponding time-frequency domain resources according to the group to which the target downlink transmission belongs.

[0119] In other embodiments of the present disclosure, the time-frequency domain resources corresponding to each group have been specified based on a standard or the like, so that the terminal device can determine the corresponding time-frequency domain resources according to the group to which the target downlink transmission belongs.

[0120] After determining the time-frequency domain resources corresponding to the target downlink transmission, the terminal device can use those time-frequency domain resources for downlink synchronization and / or broadcast reception.

[0121] In this embodiment of the disclosure, the target downlink transmission can be one or more groups. The beams corresponding to one or more groups of target downlink transmissions can be the same beam, and the time-frequency domain resources corresponding to one or more groups of target downlink transmissions can be the same or different. At least some scenarios will be described in detail below:

[0122] In one possible scenario, when the target downlink transmissions corresponding to a beam are grouped together, this group of target downlink transmissions corresponds to one or more time-frequency domain resources. The terminal device can use the one or more time-frequency domain resources corresponding to this group of target downlink transmissions to receive downlink synchronization or broadcast information.

[0123] In another possible scenario, when the target downlink transmission corresponding to the set beam is multiple groups, the set beam contains multiple beams, each group of target downlink transmissions corresponds to a different beam, and the multiple groups of target downlink transmissions can correspond to different one or more time-frequency domain resources. That is to say, each group of target downlink transmissions corresponds to different time-frequency domain resources, so that the terminal device can use the different one or more time-frequency domain resources corresponding to the multiple groups of target downlink transmissions to receive downlink synchronization or broadcast information.

[0124] It should be noted that the aforementioned set beam can be the beam through which the network device transmits the target downlink transmission. Of course, in some embodiments, the beam through which the network device transmits the target downlink transmission can be the beam corresponding to the group to which the target downlink transmission belongs; this embodiment does not limit this. The terminal device can receive downlink synchronization and / or broadcast information based on the set beam and the determined time-frequency domain resources.

[0125] In this embodiment of the disclosure, the network device sends a target downlink transmission to the terminal device. The terminal device determines the corresponding time-frequency domain resources based on the group to which the target downlink transmission belongs. Since the target downlink transmission is at least one of one or more groups of downlink transmissions, each group of downlink transmissions includes one or more combinations of narrowband synchronization signals, narrowband physical broadcast information, and narrowband system information blocks. Each group of downlink transmissions has corresponding time-frequency domain resources. The network device can indicate the time-frequency domain resources to the terminal device by sending downlink transmissions from different groups, so that the terminal device can use the indicated time-frequency domain resources to receive downlink synchronization and / or broadcast information.

[0127] like Figure 4 As shown, it includes the following steps:

[0128] At step 401, the network device generates a target downlink transmission according to a group sequence number.

[0129] The target downlink transmission is at least one of one or more groups of downlink transmissions, and each group of downlink transmissions comprises one or more combinations of a narrowband synchronization signal, a narrowband physical broadcast information, and a narrowband system information block.

[0130] In some implementations, the narrowband synchronization signal further comprises at least one of a narrowband primary synchronization signal and a narrowband secondary synchronization signal. Alternatively, in other implementations, the narrowband physical broadcast information is specifically a narrowband physical broadcast channel. It should be noted that the above-mentioned implementations can be implemented independently or in combination, and the present embodiment does not limit this.

[0131] The network device determines a group corresponding to a beam used for downlink transmission with the terminal from the multiple groups of downlink transmissions, and generates the target downlink transmission according to a group sequence number of the group.

[0132] In some embodiments, the group sequence number is a first generation parameter of the narrowband secondary synchronization signal and / or a base sequence of the narrowband secondary synchronization signal.

[0133] The base sequence of the narrowband secondary synchronization signal is generated according to the first generation parameter of the narrowband secondary synchronization signal. In some embodiments, the first generation parameter can be a cyclic shift parameter. As a possible implementation, each group of downlink transmissions in the multiple groups of downlink transmissions has one or more corresponding cyclic shift parameters, and different groups of downlink transmissions have different cyclic shift parameters to distinguish between different groups.

[0134] For example, the corresponding cyclic shift parameter of each group of downlink transmissions can be one to four, and the cyclic shift parameter used by the narrowband secondary synchronization signal in the transmitted target downlink transmission can be one of one or more cyclic shift parameters corresponding to the group. The network device can select the corresponding cyclic shift parameter from the multiple cyclic shift parameters corresponding to the group to which the target downlink transmission belongs according to different time domains or frequency domains occupied by the target downlink transmission.

[0135] The network device substitutes the selected cyclic shift parameter into a base sequence generation formula of the narrowband secondary synchronization signal to obtain the base sequence of the narrowband secondary synchronization signal. In the present embodiment, the base sequence generation formula can be the generation formula in the related protocol, or a formula corresponding to other generation rules preset, and the present embodiment does not limit this.

[0136] The terminal device generates candidate base sequences based on the base sequence generation formula and the cyclic shift parameters corresponding to each downlink transmission group. Based on the correlation between each candidate base sequence and the narrowband secondary synchronization signal in the target downlink transmission, the terminal device determines the base sequence and corresponding cyclic shift parameters of the narrowband secondary synchronization signal in the target downlink transmission. Then, based on at least one of the base sequence and corresponding cyclic shift parameters of the narrowband secondary synchronization signal in the target downlink transmission, the terminal device determines the group number to which the target downlink transmission belongs.

[0137] In other embodiments, the group number is a second generation parameter of the narrowband physical broadcast channel and / or a scrambling sequence of the narrowband physical broadcast channel.

[0138] The scrambling sequence for the narrowband physical broadcast channel is generated based on a second generation parameter of the narrowband physical broadcast channel. In some embodiments, the second generation parameter may be a scrambling initialization factor. As one possible implementation, in multiple downlink transmissions, each downlink transmission has one or more corresponding scrambling initialization factors, and different downlink transmissions have different scrambling initialization factors to distinguish between different groups.

[0139] For example, the scrambling initialization factor corresponding to each group of downlink transmissions can be the scrambling initialization factor C set in the relevant protocol. init Based on this, different offsets are superimposed, or multiplied by different coefficients, or C is applied according to other rules. init The scrambling code initialization factor values ​​are different for different downlink transmission groups because they are obtained through different transformation methods.

[0140] The network device substitutes the selected scrambling initialization factor into the scrambling sequence generation formula for the narrowband physical broadcast channel to obtain the scrambling sequence for the narrowband physical broadcast channel. In this embodiment, the generation formula for the scrambling sequence can be the generation formula in the relevant protocol, or it can be a formula corresponding to other pre-set generation rules; this embodiment does not limit this.

[0141] The terminal device generates candidate scrambling code sequences based on the scrambling code sequence generation formula and the scrambling code initialization factor corresponding to each group of downlink transmissions. Based on the correlation between each candidate scrambling code sequence and the narrowband physical broadcast channel in the target downlink transmission, the terminal device determines the scrambling code sequence and corresponding scrambling code initialization factor of the narrowband physical broadcast channel in the target downlink transmission. Then, based on at least one of the scrambling code sequence and corresponding scrambling code initialization factor of the narrowband physical broadcast channel in the target downlink transmission, the terminal device determines the group number to which the target downlink transmission belongs.

[0142] Step 402: Send the target downlink transmission to the terminal device.

[0143] The network device is pre-configured with multiple groups of downlink transmissions, and each group of downlink transmissions corresponds to a beam. Due to the different group numbers, at least one of the narrowband synchronization signal, the narrowband physical broadcast information, and the narrowband system information block in the downlink transmission generated based on the group number is different, so that the different groups of downlink transmissions can be distinguished. The terminal device can determine the group number of the group to which the target downlink transmission belongs according to one or more of the narrowband synchronization signal, the narrowband physical broadcast information, and the narrowband system information block contained in the target downlink transmission.

[0144] The group number of each group of downlink transmissions has a corresponding relationship with the time-frequency domain resource, so that the network device can indicate the configured time-frequency domain resource based on the group number of the target downlink transmission by sending the target downlink transmission to the terminal device. The terminal device can learn the time-frequency domain resource configured by the network device according to the group number, and then the terminal device uses the time-frequency domain resource for downlink synchronization and / or broadcast reception.

[0145] In some embodiments, the network device can send the target downlink transmission using a beam matching the time-frequency domain resource indicated by the target downlink transmission. Those skilled in the art can know that the network device can also send the target downlink transmission using other beams, which are not limited in this embodiment.

[0146] In the embodiments of the present disclosure, the network device sends the target downlink transmission to the terminal device, and the terminal device determines the corresponding time-frequency domain resource according to the group to which the target downlink transmission belongs. Since the target downlink transmission is at least one of one or more groups of downlink transmissions, each group of downlink transmissions includes one or more combinations of narrowband synchronization signals, narrowband physical broadcast information, and narrowband system information blocks.
