Configuration method, apparatus, and storage medium

Abstract

Embodiments of the present disclosure provide a configuration method, a device, a system, a storage medium, and a program product. The method comprises: receiving configuration information, the configuration information being used for configuring a first-type synchronization resource block and / or a second-type synchronization resource block within a first period; and on the basis of the configuration information, within the first period, not expecting to monitor the second-type synchronization resource block. In the embodiments above, a terminal may determine the first-type synchronization resource block and / or the second-type synchronization resource block within the first period on the basis of the received configuration information, since the first-type resource block also comprises second information, the second information comprised in the second-type synchronization resource block may be derived on the basis of the second information of the first-type resource block even if the second information comprised in the second-type synchronization resource block changes, and therefore, when the first-type synchronization resource block has been received within the first period, the terminal may no longer monitor the second-type synchronization resource block, thereby reducing the energy consumption of the terminal and improving resource utilization.

Description

Configuration methods, devices, and storage media Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to configuration methods, apparatus and storage media. Background Technology

[0002] When a terminal communicates with a network device, the network device can send a Synchronization Signal / Physical Broadcast Channel Block (SSB) to the terminal. After receiving the SSB, the terminal can synchronize with the network device. Summary of the Invention

[0003] Because the terminal needs to detect and decode the PBCH (Physical Broadcast Channel) corresponding to multiple symbols included in the SSB, the terminal consumes a lot of power.

[0004] This disclosure provides a configuration method, device, system, storage medium, and program product.

[0005] According to a first aspect of the embodiments of this disclosure, a configuration method is provided, the method being executed by a terminal, the method comprising:

[0006] Receive configuration information, which is used to configure a first type of synchronization resource block and / or a second type of synchronization resource block within a first period. The first type of synchronization resource block includes first information and second information; the second type of synchronization resource block includes the second information or does not include the second information. The first information remains unchanged within the first period, and the second information changes within the first period. The first period is the period of the first information.

[0007] Based on the configuration information, it is not expected that the second type of synchronization resource block will be monitored during the first period.

[0008] According to a second aspect of the embodiments of this disclosure, a configuration method is provided, the method being performed by a network device, the method comprising:

[0009] Send configuration information, which is used to configure a first type of synchronization resource block and / or a second type of synchronization resource block within a first period. The first type of synchronization resource block includes first information and second information; the second type of synchronization resource block includes the second information or does not include the second information. The first information remains unchanged within the first period, and the second information changes within the first period. The first period is the period of the first information.

[0010] According to a third aspect of the present disclosure, a communication device is provided for performing the configuration method described in the first or second aspect.

[0011] According to a fourth aspect of the present disclosure, a communication device is provided, comprising:

[0012] A processing module for executing the configuration method described in the first or second aspect.

[0013] According to a fifth aspect of the present disclosure, a terminal is provided, comprising: one or more processors; wherein the processors are configured to perform any of the methods described in the first aspect.

[0014] According to a sixth aspect of the present disclosure, a network device is provided, comprising: one or more processors; wherein the processors are configured to perform any of the methods described in the second aspect.

[0015] According to a seventh aspect of the present disclosure, a communication system is provided, comprising: a terminal and a network device, wherein the terminal is configured to implement the configuration method described in the first aspect, and the network device is configured to implement the configuration method described in the second aspect.

[0016] According to an eighth aspect of the present disclosure, a storage medium is provided that stores instructions which, when executed on a communication device, cause the communication device to perform the method as described in any one of the first or second aspects.

[0017] In this embodiment of the present disclosure, the terminal can determine the first type of synchronization resource block and / or the second type of synchronization resource block within the first period based on the received configuration information. Since the first type of resource block also includes second information, even if the second information included in the second type of synchronization resource block changes, it can still be derived based on the second information of the first type of resource block. Therefore, the terminal can stop listening to the second type of synchronization resource block when it has received the first type of synchronization resource block within the first period, thereby saving terminal energy consumption and improving resource utilization.

[0031] This disclosure provides a configuration method, device, system, storage medium, and program product.

[0032] In a first aspect, embodiments of this disclosure propose a configuration method, which is executed by a terminal, the method comprising:

[0033] Receive configuration information, which is used to configure a first type of synchronization resource block and / or a second type of synchronization resource block within a first period. The first type of synchronization resource block includes first information and second information; the second type of synchronization resource block includes the second information or does not include the second information. The first information remains unchanged within the first period, and the second information changes within the first period. The first period is the period of the first information.

[0034] Based on the configuration information, it is not expected that the second type of synchronization resource block will be monitored during the first period.

[0035] In the above embodiments, the terminal can determine the first type of synchronization resource block and / or the second type of synchronization resource block within the first period based on the received configuration information. Since the first type of resource block also includes second information, even if the second information included in the second type of synchronization resource block changes, it can still be derived based on the second information of the first type of resource block. Therefore, the terminal can stop listening to the second type of synchronization resource block when it has received the first type of synchronization resource block within the first period, thereby saving terminal energy consumption and improving resource utilization.

[0036] In conjunction with some embodiments of the first aspect, in some embodiments, the configuration information includes at least one of the following:

[0037] The number of the first type of synchronized resource blocks;

[0038] The number of the second type of synchronization resource blocks;

[0039] First indication information, the first indication information being used to enable the use of the configuration information;

[0040] Beam offset;

[0041] Modulation and coding scheme (MCS);

[0042] The second indication information is used to indicate the transmission mode adopted, and the transmission mode is used to indicate the mode of transmission resources occupied by the first type of synchronization resource block and the second type of synchronization resource block.

[0043] In the above embodiments, the configuration of the first type of resource block and the second type of resource block is determined by at least one parameter included in the configuration information, which expands the way the first type of resource block and the second type of resource block are configured and improves the flexibility of configuring the first type of resource block and the second type of resource block.

[0044] In conjunction with some embodiments of the first aspect, in some embodiments, the transmission mode includes a first mode or a second mode;

[0045] The first mode is a mode in which the first type of synchronization resource block and the second type of synchronization resource block occupy different transmission resources in the first period;

[0046] The second mode is a mode in which the first type of synchronization resource block and the second type of synchronization resource block occupy the same transmission resources within the first cycle.

[0047] In conjunction with some embodiments of the first aspect, in some embodiments, the time-domain resources occupied by the first type of synchronization resource block are greater than the time-domain resources occupied by the second type of synchronization resource block; or,

[0048] The frequency domain resources occupied by the first type of synchronization resource block are greater than those occupied by the second type of synchronization resource block.

[0049] In the above embodiments, the transmission resources occupied by the first type of synchronization resource block and the second type of synchronization resource block can be in two modes: the same and different, which expands the configuration method of the transmission mode of the first type of synchronization resource block and the second type of synchronization resource block.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, the interval between the start symbols of adjacent synchronization resource blocks within the first period is different.

[0051] In the above embodiments, the interval between the start symbols of adjacent synchronization resource blocks can be different, which can realize flexible configuration between synchronization resource blocks and improve flexibility.

[0064] In the above embodiments, since the first type of synchronization resource block and the second type of synchronization resource block are quasi-co-addressable in terms of channel parameters, the information of the second type of synchronization resource block can be derived based on the information of the first type of synchronization resource block, ensuring that the terminal does not listen to the second type of synchronization resource block and saving terminal power consumption.

[0137] For example, the MIB includes at least one of the following: system frame number, subcarrier spacing, SSB subcarrier offset, Type A location, cell prohibition information, and intra-frequency reselection information. The cell prohibition information includes both prohibition and non-prohibition information. The intra-frequency reselection information includes both allowance and disallowance of reselection within the frequency range.

[0138] For example, the physical layer content includes at least one of the following: half-frame bits, system frame count, SSB index, and cyclic redundancy check.

[0139] In some embodiments, for a half-frame with an SS / PBCH block, the first symbol index of the candidate SS / PBCH block is determined according to the SCS (Subcarrier Spacing) of the SS / PBCH block as follows, wherein index 0 corresponds to the first symbol of the first slot in the half-frame.

[0140] Optionally, in case A-15khz SCS: the index of the first symbol of the candidate SS / PBCH block is {2,8}+14·n:

[0141] - Applicable to operations without shared spectrum channel access:

[0142] —For carrier frequencies less than or equal to 3 GHz, n = 0, 1.

[0143] —For carrier frequencies greater than 3 GHz within FR1, n = 0, 1, 2, 3.

[0144] - Operations for shared spectrum channel access, as described in [15, TS 37.213], n = 0, 1, 2, 3, 4.

[0145] Optionally, for case B-30kHz SCS: the first symbol of the candidate SS / PBCH block has an index {4,8,16,20}+28·n. For carrier frequencies less than or equal to 3GHz, n=0. For carrier frequencies greater than 3GHz within FR1, n=0,1.

[0146] Referring to Figure 1C, it shows that when the SCS is 30 kHz and the carrier frequency is less than or equal to 3 GHz, the values ​​of s are 4, 8, 16, and 20. When the carrier frequency is greater than 3 GHz and less than or equal to 6 GHz, the values ​​of s are 4, 8, 16, 20, 32, 36, 44, and 48.

[0147] Optionally, for case G-960kHz SCS: the first symbol of the candidate SS / PBCH block has an index {2,9}+14·n. For carrier frequencies within FR2-2, n=0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31.

[0148] Optionally, for cell search on a carrier with a channel bandwidth of 3MHz, the UE does not expect to receive subcarriers 0 to 47 and 192 to 239 in any of the four OFDM symbols of the SS / PBCH block, where the remaining 12 resource blocks form the SS / PBCH block after puncture.

[0150] Figure 2A is an interactive schematic diagram of a configuration method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure involve information sending and receiving methods, the methods including:

[0151] Step S2101: The network device sends configuration information to the terminal.

[0152] In some embodiments, the terminal receives configuration information sent by the network device.

[0153] In some embodiments, the configuration information is used to configure a first type of synchronization resource block and / or a second type of synchronization resource block within a first period. Alternatively, the configuration information is used to configure the first type of synchronization resource block and / or the second type of synchronization resource block separately within multiple first periods. The first type of synchronization resource block and / or the second type of synchronization resource block includes cases such as a first type of synchronization resource block, a first type of synchronization resource block, and a second type of synchronization resource block. For example, the configuration information is used to configure a first type of synchronization resource block within a first period. As another example, the configuration information is used to configure both a first type of synchronization resource block and a second type of synchronization resource block within a first period.

[0154] In some embodiments, the name of the configuration information is not limited in this disclosure. For example, resource block information, resource block configuration information, etc.

[0155] Optionally, both the first type of synchronization resource block and the second type of synchronization resource block are SSBs. For example, the first type of synchronization resource block is a first type SSB, and the second type of synchronization resource block is a second type SSB.

[0156] It should be noted that the first type of synchronization resource block and the second type of synchronization resource block carry different information, and therefore are classified as different types of synchronization resource blocks. In some embodiments of this disclosure, the first type of synchronization resource block and the second type of synchronization resource block carry different information, thereby achieving physical isolation between the first information and the second information, which can also be referred to as a physical isolation mode for the first information and the second information.

[0157] In some embodiments, the first type of synchronization resource block includes first information and second information. The second type of synchronization resource block may include the second information or may not include the second information.

[0158] In this process, the first information remains unchanged during the first period. For example, this first information is the MIB (Medium Intake). The second information changes during the first period. For example, this second information is other information in the PBCH besides the MIB. This second information can be represented as oPBCH (Other Physical Broadcast Channel).

[0159] In some embodiments, system information is divided into two parts: first system information is transmitted using a first cycle, and second system information is transmitted using a second cycle. Whether there are two types of system information and the time-frequency resources / modulation coding schemes / reference signal information of each type of system information are obtained through the aforementioned first type of synchronization information block or second type of synchronization information block.

[0160] In some embodiments, the first period is the period of the first information. The first information is periodic. Optionally, the first period is continuous, or it can be said that a first period continues after the first first period. For example, the period of the first information is 40ms, 60ms, 80ms, or other values; this disclosure does not limit this.

[0161] In some embodiments, the configuration information includes at least one of the following:

[0162] (1) The number of first-class synchronization resource blocks.

[0163] In this embodiment of the disclosure, the number of the first type of synchronization resource blocks refers to the number of the first type of synchronization resource blocks within the first period. Alternatively, it can be described as the number of the first type of synchronization resource blocks included in each first period.

[0164] For example, the number of the first type of synchronization resource blocks is 1, 2, 3 or other numbers.

[0165] In some embodiments, the configuration information includes a first quantity, which is the number of first-class synchronization resource blocks.

[0166] (2) The number of second-class synchronization resource blocks.

[0167] In this embodiment of the disclosure, the number of the second type of synchronization resource blocks refers to the number of the second type of synchronization resource blocks within the first period. Alternatively, it can be described as the number of the second type of synchronization resource blocks included in each first period.

[0168] For example, the number of the second type of synchronization resource blocks is 4, 6, 8 or other numbers.

[0169] In some embodiments, the configuration information includes a second quantity, which is the number of second-type synchronization resource blocks.

[0170] (3) First instruction information.

[0171] In some embodiments, the first indication information is used to enable the use of configuration information, indicating that the terminal can use the configuration information. Alternatively, the first indication information is used to indicate that the terminal supports the use of a first type of synchronization resource block and a second type of synchronization resource block.

[0172] The first indication information includes a third number of bits. For example, the third number is 1, 2, or other values. If the third value is 1, it means that the configuration information includes 1 bit of the first indication information. If the first indication information is 1, the configuration information is enabled. If the first indication information is 0, the configuration information is not used.

[0173] (4) Beam offset.

[0174] In some embodiments, the beam offset refers to the offset relative to a specific beam. For example, if the terminal includes eight beams, namely beams 1 to 8, the beam offset can be the offset relative to beam 1, the offset to beam 2, or the offset relative to other beams. Alternatively, the beam offset refers to the offset between selected adjacent beams. For example, if the terminal includes eight beams, namely beams 1 to 8, and the beam offset is 3, beam 1 has been selected, then the next beam is beam 4, the next beam after that is beam 7, the next beam after that is beam 2, and so on.

[0175] (5) MCS.

[0176] In some embodiments, the MCS is used to represent data transmission rate and coding efficiency. Optionally, the MCS includes at least one of modulation scheme and coding rate. The modulation scheme includes any one of BPSK (Binary Phase Shift Keying), QPSK (Quadrature Phase Shift Keying), 16-QAM (16 Quadrature Amplitude Modulation), 64-QAM, and 256-QAM.

[0177] (6) Second instruction information.

[0178] In some embodiments, the second indication information is used to indicate the transmission mode employed. The transmission mode indicates the mode of transmission resources occupied by the first type of synchronization resource block and the second type of synchronization resource block. It should be noted that the transmission resources occupied by the first type of synchronization resource block and the second type of synchronization resource block can also be described as the first type of synchronization resource block and the second type of synchronization resource block occupying different TF (time-frequency domain) resource grids.

[0179] Optionally, the transmission mode includes a first mode or a second mode. The first mode is where the transmission resources occupied by the first type of synchronization resource block and the second type of synchronization resource block within the first period are different. The second mode is where the transmission resources occupied by the first type of synchronization resource block and the second type of synchronization resource block within the first period are the same.

[0180] Optionally, the transmission resources include time-domain resources and / or frequency-domain resources. Wherein, if the transmission resources include time-domain resources, the first mode is a mode in which the time-domain resources occupied by the first type of synchronization resource block and the second type of synchronization resource block within the first period are different. The second mode is a mode in which the time-domain resources occupied by the first type of synchronization resource block and the second type of synchronization resource block within the first period are the same. If the transmission resources include frequency-domain resources, the first mode is a mode in which the frequency-domain resources occupied by the first type of synchronization resource block and the second type of synchronization resource block within the first period are different. The second mode is a mode in which the frequency-domain resources occupied by the first type of synchronization resource block and the second type of synchronization resource block within the first period are the same. If the transmission resources include both time-domain resources and frequency-domain resources, the first mode is a mode in which the time-domain resources occupied by the first type of synchronization resource block and the second type of synchronization resource block within the first period are different. The second mode is a mode in which the time-domain resources occupied by the first type of synchronization resource block and the second type of synchronization resource block within the first period are the same.

[0181] In this embodiment of the disclosure, the configuration information includes different parameters to enable the configuration of different first-type synchronization resource blocks and second-type synchronization resource blocks, thereby expanding the ways in which the configuration information configures the first-type synchronization resource blocks and second-type synchronization resource blocks and improving the flexibility of configuring the first-type synchronization resource blocks and second-type synchronization resource blocks.

[0182] In some embodiments, the time-domain resources occupied by the first type of synchronization resource block are greater than those occupied by the second type of synchronization resource block. For example, the first type of synchronization resource block occupies 4 OFDM symbols in the time domain, and the second type of synchronization resource block occupies 3 OFDM symbols in the time domain. Alternatively, the frequency-domain resources occupied by the first type of synchronization resource block are greater than those occupied by the second type of synchronization resource block. For example, the first type of synchronization resource block occupies 20 subcarriers in the frequency domain, and the second type of synchronization resource block occupies 15 subcarriers in the frequency domain.

[0183] In some embodiments, the interval between the start symbols of adjacent synchronization resource blocks within the first period is different. For example, the first period includes a first type of synchronization resource block, a second type of synchronization resource block 1, a second type of synchronization resource block 2, and a third type of synchronization resource block 3. The interval between the first type of synchronization resource block and the second type of synchronization resource block 1 is 4 symbols, the interval between the second type of synchronization resource block 1 and the second type of synchronization resource block 2 is 3 symbols, and the interval between the second type of synchronization resource block 2 and the second type of synchronization resource block 3 is 5 symbols.

[0184] It should be noted that the interval between the start symbols of adjacent synchronization resource blocks within the first period can also be the same. For example, if the first period includes a first type of synchronization resource block, a second type of synchronization resource block 1, a second type of synchronization resource block 2, and a third type of synchronization resource block 3, the interval between the first type of synchronization resource block and the second type of synchronization resource block 1, the interval between the second type of synchronization resource block 1 and the second type of synchronization resource block 2, and the interval between the second type of synchronization resource block 2 and the second type of synchronization resource block 3 are all 3 symbols.

[0185] In some embodiments, the starting symbols of the first type of synchronization resource block and the second type of synchronization resource block are not limited. The starting symbols of the first type of synchronization resource block and the second type of synchronization resource block can be odd or even, that is, the starting symbols of the first type of synchronization resource block and the second type of synchronization resource block can be any symbol.

[0186] In some embodiments, the second type of synchronization resource block further includes information carried by the system information resource block. In this embodiment, by using the second type of synchronization resource block to carry the information carried by the system information resource block, the load on the system information resource block can be reduced, and the types of information carried by the second type of synchronization resource block can be expanded. Optionally, if the second type of synchronization resource block does not include second information, the second type of synchronization resource block includes the information carried by the system information resource block. Alternatively, if the second information of the second type of synchronization resource block is empty, the second type of synchronization resource block includes the information carried by the system information resource block.

[0187] It should be noted that the second type of synchronization resource block does not include the second information, which can also be understood as reducing the number of bits carrying the second information in the second type of synchronization resource block to 0. The second type of synchronization resource block does not include the second information by reducing the number of bits carrying the second information.

[0188] In some embodiments, the information carried by the system information resource block includes at least one of the following: cell selection parameters, system information resource block scheduling information, random access parameters, channel configuration information, cell reselection parameters, neighbor cell information, and cell access control related information.

[0189] In some embodiments, if the second type of synchronization resource block does not include the second information, the second information is carried in the system information resource block. Alternatively, if the second information of the second type of synchronization resource block is empty, the second information is carried in the system information resource block. In this embodiment, by reducing the second information of the second type of synchronization resource block and carrying the reduced second information in the system information resource block, the load on the second type of synchronization resource block can be reduced, and resource utilization can be improved. Optionally, if the second information of the second type of synchronization resource block is empty, a synchronization signal can be added at the location of the second information.

[0190] In some embodiments, the configuration information further includes: third indication information, which enables skipping system information resource blocks; and the number of system information resource blocks to be skipped. In this embodiment, the third indication information indicates that the terminal can skip system information resource blocks, and the number of system information resource blocks to be skipped can also be determined. Therefore, skipping the listening system information resource blocks can be performed based on the third indication information and the number of system information resource blocks to be skipped.

[0191] It should be noted that the above embodiments describe the parameters included in the configuration information, as well as the first type of synchronization resource block and the second type of synchronization resource block. The following examples illustrate which situations the configuration information may include.

[0192] In some embodiments, the first information is the MIB (Master Indication Block), and the second information is the oPBCH, as an example. The first type of synchronization resource block and the second type of synchronization resource block occupy different transmission resources, and the first type of synchronization resource block occupies more symbols than the second type of synchronization resource block. Referring to Figure 2B, within one MIB cycle, the first type of synchronization resource block includes both the MIB and the oPBCH, occupying 4 symbols, while the second type of synchronization resource block only includes the oOBCH, occupying 3 symbols.

[0193] It should be noted that the starting symbols for the first and second type of synchronization resource blocks can be either odd or even. Furthermore, the interval between adjacent synchronization resource blocks is not constant within the same MIB period. This configuration information may include at least one of the following parameters: the number of first type synchronization resource blocks, the number of second type synchronization resource blocks, first indication information, and beam offset.

[0194] In other embodiments, the example is given where the first information is MIB and the second information is oPBCH. The first type of synchronization resource block and the second type of synchronization resource block occupy the same transmission resources, and the number of symbols occupied by the first type of synchronization resource block is equal to the number of symbols occupied by the second type of synchronization resource block. Referring to Figure 2C, within one MIB cycle, the first type of synchronization resource block includes both the MIB and oPBCH, occupying 4 symbols, while the second type of synchronization resource block includes only oOBCH, also occupying 4 symbols.

[0195] It should be noted that the configuration information may include at least one of the following parameters: the number of first-type synchronization resource blocks, the number of second-type synchronization resource blocks, first indication information, MCS, and beam offset.

[0196] In step S2102, the terminal does not expect to listen to the second type of synchronization resource block within the first cycle based on the configuration information.

[0197] In this embodiment of the present disclosure, after the terminal determines the configuration of the first type of synchronization resource block and the second type of synchronization resource block in the first period, since the first type of synchronization resource block includes the first information and the second information, while the second type of synchronization resource block only includes the second information, the terminal may not want to listen to the second type of synchronization resource block in the first period, or the terminal may skip listening to the second type of synchronization resource block. Since the number of synchronization resource blocks listened to by the terminal is reduced, the terminal energy consumption can be saved.

[0198] In some embodiments, the first type of synchronization resource block and the second type of synchronization resource block are quasi-co-addressable in terms of channel parameters, and are transmitted in the form of an index at the same center frequency location. In this embodiment, since the first type of synchronization resource block and the second type of synchronization resource block are quasi-co-addressable in terms of channel parameters, the information of the second type of synchronization resource block can be derived based on the information of the first type of synchronization resource block.

[0199] Optionally, the channel parameters include at least one of the following: Doppler spread, Doppler shift, average gain, average delay, delay spread, and spatial reception parameters. For example, the first type of synchronization resource block and the second type of synchronization resource block are quasi-co-located in at least one of the following: Doppler spread, Doppler shift, average gain, average delay, delay spread, and spatial reception parameters.

[0200] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0201] In some embodiments, “get,” “obtain,” “receive,” “transmit,” “bidirectional transmission,” and “send and / or receive” can be used interchangeably and can be interpreted as receiving from other entities, obtaining from protocols, obtaining from higher layers, obtaining through self-processing, or autonomous implementation, among other meanings.

[0202] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transfer,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0203] In some embodiments, terms such as "certain," "preset," "default," "set," "indicated," "a certain," "any," and "first" can be used interchangeably. "Certain A," "preset A," "default A," "set A," "indicated A," "a certain A," "any A," and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, a certain A, any A, or first A, but are not limited thereto.

[0204] The method for determining the start time involved in the embodiments of this disclosure may include at least one of steps S2101 to S2102. For example, at least one of steps S2101 to S2102 may be implemented as an independent embodiment, but is not limited thereto.

[0205] In some embodiments, at least one of steps S2101 to S2102 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0206] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0207] In the above embodiments, the terminal can determine to skip listening to synchronization information based on the parameters configured in the network device. This enables the terminal to listen to some synchronization information and skip listening to others. Since the terminal reduces the amount of synchronization information it listens to, it can save terminal energy and improve the efficiency of listening to synchronization information.

[0208] Figure 3 is a flowchart illustrating a configuration method according to an embodiment of the present disclosure. As shown in Figure 3, the present disclosure relates to a configuration method, which includes:

[0225] The second mode is a mode in which the first type of synchronization resource block and the second type of synchronization resource block occupy the same transmission resources within the first cycle.

[0226] In some embodiments, the time-domain resources occupied by the first type of synchronization resource block are greater than the time-domain resources occupied by the second type of synchronization resource block; or,

[0227] The frequency domain resources occupied by the first type of synchronization resource block are greater than those occupied by the second type of synchronization resource block.

[0228] In some embodiments, the interval between the start symbols of adjacent synchronization resource blocks within the first period is different.

[0229] In some embodiments, the second type of synchronization resource block may also include information carried by the system information resource block.

[0230] In some embodiments, the information carried by the system information resource block includes at least one of the following:

[0231] Cell selection parameters, system information resource block scheduling information, random access parameters, channel configuration information, cell reselection parameters, neighbor cell information, and cell access control related information.

[0232] In some embodiments, if the second type of synchronization resource block does not include the second information, the second information is carried in the system information resource block.

[0241] Figure 4 is a flowchart illustrating a configuration method according to an embodiment of the present disclosure. As shown in Figure 4, the present disclosure relates to a configuration method, which includes:

[0242] Step S4101: The network device configures the SSB for the terminal.

[0243] In some embodiments, the physical isolation mode of MIB content and oPBCH content, and different TF resource grids, are used to deliver SSB.

[0244] The configured SSBs include the following cases:

[0245] The MIB+oPBCH that transmits SSBs has more symbols than the SSB that only transmits oPBCHs.

[0246] The configured SSB start symbols include both odd and even numbers.

[0247] The interval between configured SSB boot symbols is not constant.

[0248] Information representing the transport mode within a MIB content period includes at least the following:

[0249] Number of MIB+oPBCHs carrying SSB;

[0250] Only the number of OPBCHs for transmitting SSB;

[0251] Enable flag for whether to use physical isolation transmission method;

[0252] Beam offset.

[0253] Correspondingly, the behavior on the terminal side:

[0254] If the Physical Isolation Transport Mode flag is present and set to "Enabled", the terminal does not want to monitor the X oPBCH SSB indicated by the "Number of oPBCHs Transmitting Only SSBs" field in the MIB+oPBCH Transport SSB.

[0255] The UE can assume that it is indexed by blocks at the same center frequency location (increasing Δ in adjacent MIB content periods). bso mod(L max The SS / PBCH blocks transmitted are quasi-co-addressable in terms of Doppler spread, Doppler shift, average gain, average delay, delay spread, and (where applicable) spatial Rx parameters. Except as specified in [5, TS 38.213], the UE shall not assume quasi-co-addressability for any other SS / PBCH block transmission.

[0256] In some embodiments, the physical isolation mode of MIB content and oPBCH content has the same TF resource grid for transmitting SSB.

[0257] Among them, the MIB+oPBCH that transmits SSBs has the same number of symbols as the SSB that only transmits oPBCHs.

[0258] Information representing the transport mode within a MIB content period includes at least the following:

[0259] Number of MIB+oPBCHs carrying SSB;

[0260] Only the number of OPBCHs for transmitting SSB;

[0261] Enable flag for whether to use physical isolation transmission method.

[0262] The corresponding terminal behavior:

[0263] If the Physical Isolation Transport Mode flag is present and set to "Enabled", the terminal does not want to monitor the X oPBCH SSB indicated by the "Number of oPBCHs Transmitting Only SSBs" field in the MIB+oPBCH Transport SSB.

[0264] The UE may assume that SS / PBCH blocks transmitted at the same center frequency location with block index (incrementing by mod(L_max) in adjacent MIB content periods) are quasi-co-addressable in terms of Doppler spread, Doppler shift, average gain, average delay, delay spread, and (where applicable) spatial Rx parameters. The UE may not assume quasi-co-addressability for any other SS / PBCH block transmission except as specified in [5, TS 38.213].

[0265] It should be noted that the oPBCH bit can be reduced to 0, and the number of symbols transmitted for oPBCH can be limited to synchronization signals.

[0266] The oPBCH content can be optionally placed in the SIB message.

[0267] Optional MIB instructions include SIB skip information, which includes at least the following:

[0268] Indicates whether to skip the SIB enable flag.

[0269] Number of SIBs to skip.

[0270] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0271] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits.

For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules.

For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules.

[0289] The terminal can determine the first type of synchronization resource block and / or the second type of synchronization resource block within the first period based on the received configuration information. Since the first type of resource block also includes second information, even if the second information included in the second type of synchronization resource block changes, it can still be derived based on the second information of the first type of resource block. Therefore, the terminal can stop listening to the second type of synchronization resource block when it has received the first type of synchronization resource block within the first period, thus saving terminal energy consumption and improving resource utilization.
