[0189] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0190] Some terms in the embodiments of the present application are explained below to facilitate understanding by those of ordinary skill in the art.

[0191] (1) In the embodiments of the present application, the terms “network” and “system” are often used alternately, but those of ordinary skill in the art can understand their meanings.

[0192] (2) In the embodiments of the present application, the term “multiple” refers to two or more, and other quantifiers are similar.

[0193] (3) In the embodiments of the present application, the terms “first” and “second” are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by “first” and “second” can explicitly or implicitly include one or more of the features.

[0194] (4) In the embodiments of the present application, "and / or" describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0195] (5) The UE involved in the embodiments of the present application can refer to a device that provides voice and / or data connectivity to a user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem, etc. In different systems, the name of the UE can also be different. The wireless UE can communicate with one or more core networks (CN) through a radio access network (RAN). The wireless UE can be a mobile terminal device, such as a mobile phone (also known as a "cellular" phone) and a computer with a mobile terminal device, for example, it can be a portable, pocket, handheld, built-in computer, or vehicle-mounted mobile device that exchanges language and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), etc. The wireless UE can also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, which is not limited in the embodiments of the present application.

[0196] (6) The network-side device involved in the embodiments of the present application can be a base station, which can include multiple cells serving UEs. According to different application scenarios, the base station can also be referred to as an access point, or can be a device in an access network that communicates with wireless terminal devices through one or more sectors over an air interface, or other names. The network-side device can be used to exchange the received air frames and Internet Protocol (IP) packets as a router between the wireless terminal device and the rest of the access network, which can include an IP communication network. The network-side device can also coordinate the management of the properties of the air interface. For example, the network-side device involved in the embodiments of the present application can be a network-side device (Base Transceiver Station, BTS) in the Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA), or a network-side device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolved network-side device (evolutional Node B, eNB or e-NodeB) in a long term evolution (LTE) system, or a 5G base station (gNB) in a next generation system (5G network architecture), or a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., which are not limited in the embodiments of the present application. In some network structures, the network-side device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be arranged geographically apart.

[0197] The network side device and the UE can each use one or more antennas for multi-input multi-output (MIMO) transmission, which can be single user MIMO (SU-MIMO) or multiple user MIMO (MU-MIMO). According to the shape and number of root antenna combinations, the MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or can be diversity transmission or precoding transmission or beamforming transmission, etc.

[0198] The technical solutions provided by the embodiments of the present application can be applied to various systems, especially 5G systems. For example, the applicable systems can be global system for mobile communication (GSM) system, code division multiple access (CDMA) system, wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, long term evolution (LTE) system, long term evolution advanced (LTE-A) system, universal mobile system (UMTS), worldwide interoperability for microwave access (WiMAX) system, 5G NR system, etc. Among these various systems, there are UEs and network side devices. The system can also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0199] In the LTE system, the transmission position of the SSB is fixed and unchanged. Figure 1Take SCS = 15KHz as an example for a radio frame. In this radio frame, the SSB transmission position is in time slot #0 and time slot #5. Time slot #4 and time slot #9 are used for unicast scheduling. Time slot #0, time slot #4, time slot #5 and time slot #9 are defaulted to Normal Cyclic Prefix (NCP). The 6-bit ECP time slot indication information indicates whether other time slots except the time slot containing the initial access signal and the time slot for unicast scheduling are ECP time slots. Figure 1 As shown, in the ECP time slot indication information, b0 indicates whether time slot #1 is an ECP time slot, b1 indicates whether time slot #2 is an ECP time slot, b2 indicates whether time slot #3 is an ECP time slot, b3 indicates whether time slot #6 is an ECP time slot, b4 indicates whether time slot #7 is an ECP time slot, and b5 indicates whether time slot #8 is an ECP time slot.

[0200] In the NR system, a radio frame contains multiple candidate positions. Figure 2A Taking the case of subcarrier spacing (SCS) = 15KHz, a radio frame is used as an example to illustrate. In this radio frame, there are time slots #0 to time slots #9, of which time slots #0 to time slots #3 can all send SSB; in addition, time slots #0 to time slots #3 each have 2 candidate positions for sending SSB. Figure 2B Taking time slot #0 as an example, time slot #0 contains 14 position symbols, recorded as position symbol #0 to position symbol #13, position symbol #2 to position symbol #5 are candidate positions for sending SSB, and position symbol #8 to position symbol #11 are candidate positions for sending SSB. Among them, the SSB structure in position symbol #8 to position symbol #11 can be referred to Figure 2C As shown in the figure, SSB includes the Primary Synchronous Signal (PSS), the Secondary Synchronous Signal (SSS) and the Physical Broadcast Channel (PBCH). In addition to the symbols after the PSS and SSS being PBCH data, there is also PBCH data at both ends of the SSS. When the UE searches for a cell, it performs a synchronization search based on the PSS / SSS and receives the PBCH after completing the synchronization search. Figures 2A-2C As can be seen, there are up to eight candidate locations in a radio frame where SSBs can be sent. This means that SSBs can be transmitted at any or multiple candidate locations, and the number of time slots and symbol positions for sending SSBs are not fixed. Therefore, the method for determining ECP time slots in the above LTE system is not applicable to NR systems.

[0201] The embodiment of the present application is to solve the problem of determining the ECP slot in the NR system, and provides an ECP slot determination method, a user equipment and a network side device. In the embodiment, the ECP slot indication information can indicate the slot containing SSB or not. The UE flexibly determines whether the ECP slot indication information indicates the slot containing SSB according to the indication of the network side device. Then, the ECP slot in the preset unit length sent by the network side device is determined according to the determination result and the ECP slot indication information, which can be compatible with the flexibility of the existing design and ensure that the network side device can be flexibly deployed.

[0202] The embodiment of the present application can be applied to the 5G system, and can also be applied to other systems.

[0203] The embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0204] In the description process, the implementation of the UE and the network side device will be described respectively, and the cooperation of the two will be described. Such a description method does not mean that the two must be cooperated or must be implemented separately. In fact, when the UE and the network side device are implemented separately, they also solve the problems of the UE and the network side device respectively. When the two are used together, better technical effects can be obtained.

[0205] Figure 3 The first ECP slot determination method provided by the embodiment of the present application has a flow chart of interaction as shown in Figure 3 , which can include:

[0206] Step S301: The network side device sends the ECP slot indication information of the preset unit length to the UE according to whether the ECP slot indication information indicates the slot containing SSB.

[0207] In the NR system, the slot for sending SSB is flexible, and SSB can be transmitted through any / multiple candidate positions. Therefore, the number and position symbol of the slot for sending SSB are not fixed, and whether the ECP slot indication information indicates the slot containing SSB is also flexible. For example, the network side device determines whether the ECP slot indication information indicates the slot containing SSB according to the business demand.

[0208] In the implementation, the network side device determines the ECP slot indication information of the preset unit length sent to the UE according to whether the ECP slot indication information indicates the slot containing SSB. That is, for a preset unit length, the corresponding ECP slot indication information is different when indicating the slot containing SSB and not indicating the slot containing SSB.

[0209] In the embodiment, the ECP slot indication information includes a plurality of sub-indication information, and each sub-indication information is used to indicate whether the corresponding time slot is an ECP time slot. That is, if the ECP time slot indication information indicates a time slot containing an SSB, there is sub-indication information in the ECP time slot indication information for indicating whether the time slot containing the SSB is an ECP time slot; if the ECP time slot indication information does not indicate a time slot containing an SSB, there is no sub-indication information in the ECP time slot indication information for indicating whether the time slot containing the SSB is an ECP time slot.

[0210] In step S302, the UE determines whether the ECP time slot indication information indicates a time slot containing an SSB according to the indication of the network side device.

[0211] As described above, for a preset unit length, the corresponding ECP time slot indication information is different when indicating a time slot containing an SSB and when not indicating a time slot containing an SSB. Therefore, the UE needs to determine whether the ECP time slot indication information indicates a time slot containing an SSB according to the indication of the network side device, and then the UE can accurately determine the ECP time slot in the preset unit length after receiving the time slot of the preset unit length.

[0212] In step S303, the UE determines the ECP time slot in the preset unit length sent by the network side device according to the determination result of whether the ECP time slot indication information indicates a time slot containing an SSB and the ECP time slot indication information.

[0213] In the above scheme, the ECP time slot indication information can indicate a time slot containing an SSB or not indicate a time slot containing an SSB. The UE flexibly determines whether the ECP time slot indication information indicates a time slot containing an SSB according to the indication of the network side device, and then accurately determines the ECP time slot in the preset unit length sent by the network side device according to the determination result and the ECP time slot indication information, which can be compatible with the flexibility of the existing design and ensure that the network side device can be flexibly deployed.

[0214] Figure 4 The second ECP time slot determination method provided by the embodiment of the application can include the following steps, as shown in the interaction flowchart of the second ECP time slot determination method provided by the embodiment of the application. Figure 4

[0215] In step S401, the network side device sends the ECP time slot indication information of a preset unit length to the UE according to whether the ECP time slot indication information indicates a time slot containing an SSB.

[0216] The specific implementation of step S401 can refer to the above embodiment, which will not be described here.

[0217] In step S402, the network side device sends high-layer signaling containing configuration information to the UE. ​

[0218] The high-layer signaling can be a system broadcast message transmitted through a broadcast control channel, a broadcast multicast configuration message transmitted through a multicast control channel, a UE-based radio link control message, or a media access layer-based control message, and the embodiments are not limited in this regard.

[0219] In an implementation, a configuration information, denoted as isSSBslotinlcuded, can be added to the high-layer signaling. For example, when isSSBslotinlcuded is configured as 1, it indicates that the ECP slot indication information indicates the slot containing SSB, i.e., the ECP slot indication information includes sub-indication information for indicating whether the slot containing SSB is an ECP slot; when isSSBslotinlcuded is configured as 0, it indicates that the ECP slot indication information does not indicate the slot containing SSB, i.e., the ECP slot indication information does not include sub-indication information for indicating whether the slot containing SSB is an ECP slot.

[0220] It can be understood that the configuration of isSSBslotinlcuded is only an example. When isSSBslotinlcuded is configured as 1, it can also indicate that the ECP slot indication information does not indicate the slot containing SSB; when isSSBslotinlcuded is configured as 0, it can also indicate that the ECP slot indication information indicates the slot containing SSB; or isSSBslotinlcuded can also be configured as other values, and the application is not limited in this regard, and the configuration can be performed according to the actual application scenario.

[0221] Step S403: The UE determines whether the ECP slot indication information indicates the slot containing SSB according to the configuration information.

[0222] As described above, the configuration value of the configuration information indicates whether the ECP slot indication information indicates the slot containing SSB, and correspondingly, the UE can determine whether the ECP slot indication information indicates the slot containing SSB according to the configuration information. The specific configuration of the configuration information can be referred to the above steps, and will not be described here.

[0223] Step S404: The UE determines the ECP slot in the preset unit length transmitted by the network-side device according to the determination result of whether the ECP slot indication information indicates the slot containing SSB and the ECP slot indication information.

[0224] The specific implementation of step S404 can be referred to the above embodiments, and will not be described here.

[0225] The scheme adds configuration information in high-layer signaling of the network side device to perform explicit indication, and the configuration information represents whether the ECP slot indication information indicates a slot containing an SSB. The UE can directly determine whether the ECP slot indication information indicates a slot containing an SSB according to the configuration information.

[0226] Figure 5 A third ECP slot determination method provided by an embodiment of the present application has a flowchart of interactions as shown in Figure 5

[0227] Step S501: The network side device sends preset unit length ECP slot indication information to the UE according to whether the ECP slot indication information indicates a slot containing an SSB.

[0228] The specific implementation of step S501 can refer to the above embodiments, which will not be described here.

[0229] Step S502: The network side device sends high-layer signaling without configuration information to the UE.

[0230] The specific implementation of the high-layer signaling can refer to the above embodiments, which will not be described here.

[0231] In implementation, if the network side device represents whether the ECP slot indication information indicates a slot containing an SSB based on a default rule, the network side device can send high-layer signaling without configuration information to the UE. The UE and the network side device use the same default rule, and the default rule can be set according to an actual application scenario. In some optional embodiments, the default rule is that the ECP slot indication information indicates a slot containing an SSB. In other optional embodiments, the default rule is that the ECP slot indication information does not indicate a slot containing an SSB.

[0232] Step S503: The UE determines whether the ECP slot indication information indicates a slot containing an SSB based on the default rule.

[0233] When the network side device sends high-layer signaling without configuration information, it means that whether the ECP slot indication information indicates a slot containing an SSB is to be determined based on a default rule. For example, if the default rule is that the ECP slot indication information indicates a slot containing an SSB, the UE determines that the ECP slot indication information indicates a slot containing an SSB after receiving the high-layer signaling without configuration information. Or, if the default rule is that the ECP slot indication information does not indicate a slot containing an SSB, the UE determines that the ECP slot indication information does not indicate a slot containing an SSB after receiving the high-layer signaling without configuration information.

[0234] ​Step S504: The UE determines the ECP time slot within the preset unit length sent by the network side device based on the determination result of whether the ECP time slot indication information indicates a time slot containing SSB and the ECP time slot indication information.

[0235] The specific implementation of step S504 can be found in the above embodiment and will not be described again here.

[0236] In the above solution, the UE and the network-side device adopt the same default rules. In this way, the network-side device sends high-layer signaling that does not contain configuration information to the UE. The UE determines whether the ECP time slot indication information indicates a time slot containing SSB based on the default rules, which can make explicit indication more convenient and meet the needs of different application scenarios.

[0237] It is understandable that the above Figure 4 Examples and Figure 5 The embodiments can be combined, that is, if it can be determined based on the default rule whether the ECP time slot indication information indicates a time slot containing SSB, the network side device sends a high-level signaling without configuration information to the UE; otherwise, it sends a high-level signaling containing configuration information to the UE. The specific implementation method can be referred to above Figure 4 Examples and Figure 5 The embodiments will not be described in detail here.

[0238] Figure 6 The interactive flow chart of the fourth ECP time slot determination method provided in the embodiment of the present application is as follows: Figure 6 As shown, this may include:

[0239] Step S601: If the network side device determines that the ECP time slot indication information indicates a time slot containing SSB, the total number of configuration sub-indication information is greater than the first preset number of ECP time slot indication information; otherwise, the total number of configuration sub-indication information is not greater than the first preset number of ECP time slot indication information.

[0240] As described above, the sub-indication information is used to indicate whether the corresponding time slot is an ECP time slot.

[0241] In some optional implementations, the first preset number is the difference between the total number of time slots in the preset unit length and the time slot adjustment amount, i.e., the first preset number N1 = slotduration-K, where slotduration is the total number of time slots in the preset unit length and K is the time slot adjustment amount.

[0242] Taking SCS=15KHz and the preset unit length as one radio frame as an example, the total number of time slots within the preset unit length is 10, that is, when SCS=15KHz, there are 10 time slots in one radio frame.

[0243] The time slot adjustment amount can be 0, 1, 4, etc. The embodiment does not make specific limitation on the determination manner of the time slot adjustment amount, for example:

[0244] 1) can be a value predetermined by a protocol;

[0245] 2) can also be a value configured to the UE by the network side device;

[0246] 3) can also be a value calculated according to a system message, for example, according to the system message, taking the number of time slots occupied by the SSB sent by the network side device as the K value; or taking the maximum number of time slots containing SSB in a preset unit length as the K value.

[0247] The above several determination manners of the time slot adjustment amount are only exemplary, and in the implementation, as long as the UE determines the time slot adjustment amount in the same manner as the network side device, the specific implementation is not described here.

[0248] Step S602: The UE determines whether the total number of sub-indication information in the ECP time slot indication information of a preset unit length is greater than a first preset number; if yes, it is determined that the ECP time slot indication information indicates time slots containing SSB; otherwise, it is determined that the ECP time slot indication information does not indicate time slots containing SSB.

[0249] In the embodiment, the UE can determine the time slot adjustment amount in any of the above manners, and then determine the first preset number; by comparing the total number of sub-indication information in the ECP time slot indication information of a preset unit length (that is, how many time slots can be indicated by the ECP time slot indication information) with the first preset number; if the total number of sub-indication information in the ECP time slot indication information of the preset unit length is greater than the first preset number, it is determined that the ECP time slot indication information indicates time slots containing SSB; if the total number of sub-indication information in the ECP time slot indication information of the preset unit length is not greater than the first preset number, it is determined that the ECP time slot indication information does not indicate time slots containing SSB.

[0250] Step S603: The UE determines the ECP time slot in a preset unit length sent by the network side device according to the determination result of whether the ECP time slot indication information indicates time slots containing SSB and the ECP time slot indication information.

[0251] The specific implementation of the step S603 can refer to the above embodiment, which is not described here.

[0252] The above scheme, the network side device configures the size relationship between the total number of sub-indication information in the ECP time slot indication information and the first preset number according to whether the ECP time slot indication information indicates a time slot containing SSB; correspondingly, the UE can accurately determine whether the ECP time slot indication information indicates a time slot containing SSB based on the size relationship between the total number of sub-indication information in the ECP time slot indication information and the first preset number, can more flexibly perform implicit indication, and meets the needs of different application scenarios.

[0253] Figure 7 The interaction flowchart of the fifth ECP time slot determination method provided by the embodiment of the application is shown in FIG. 7, and can include the following steps. Figure 7

[0254] Step S701: If the network side device determines that the ECP time slot indication information indicates a time slot containing SSB, the network side device configures the first ECP time slot indication information corresponding to the preset unit length and not indicating a time slot containing SSB, and the second ECP time slot indication information indicating a time slot containing SSB; and after sending the first ECP time slot indication information to the UE, the network side device sends the second ECP time slot indication information to the UE; if the network side device determines that the ECP time slot indication information does not indicate a time slot containing SSB, the network side device configures one ECP time slot indication information corresponding to the preset unit length.

[0255] In implementation, for any preset unit length, two sets of ECP time slot indication information can be configured, the first ECP time slot indication information contains a second preset number of sub-indication information and does not indicate a time slot containing SSB; the second ECP time slot indication information contains a third preset number of sub-indication information and indicates a time slot containing SSB, and in some embodiments, the second ECP time slot indication information also indicates a time slot not containing SSB which is not indicated in the first ECP time slot indication information.

[0256] In the embodiment, in order to enable the UE to distinguish the first ECP time slot indication information and the second ECP time slot indication information, the network side device needs to first send the first ECP time slot indication information to the UE, and then send the second ECP time slot indication information to the UE.

[0257] In some optional embodiments, the sum of the total number of sub-indication information in the first ECP time slot indication information and the total number of sub-indication information in the second ECP time slot indication information is the total number of time slots in the preset unit length. That is, the total number of time slots N0 in the preset unit length = N2+N3, where N2 is the total number of sub-indication information in the first ECP time slot indication information (i.e., the second preset number), and N3 is the total number of sub-indication information in the second ECP time slot indication information (i.e., the third preset number).

[0258] ​Still taking the example of SCS=15KHz and a preset unit length being one radio frame, the total number of time slots in the preset unit length is 10, that is, there are 10 time slots in one radio frame when SCS=15KHz; if the total number of sub-indication information in the first ECP time slot indication information is 6, then the total number of sub-indication information in the second ECP time slot indication information is 4.

[0259] Step S702: The UE determines, for any preset unit length, that the ECP time slot indication information does not indicate a time slot containing an SSB if one ECP time slot indication information corresponding to the preset unit length is received; and determines that the first ECP time slot indication information does not indicate a time slot containing an SSB and the second ECP time slot indication information indicates a time slot containing an SSB if two ECP time slot indication information corresponding to the preset unit length is received.

[0260] In this embodiment, the UE determines that the ECP time slot indication information does not indicate a time slot containing an SSB if only one ECP time slot indication information corresponding to a preset unit length is received;

[0261] The UE determines that the first ECP time slot indication information received first does not indicate a time slot containing an SSB and the second ECP time slot indication information received later indicates a time slot containing an SSB if two ECP time slot indication information corresponding to a preset unit length is received.

[0262] Step S703: The UE determines the ECP time slots in a preset unit length sent by the network side device according to the determination result of whether the ECP time slot indication information indicates a time slot containing an SSB and the ECP time slot indication information.

[0263] The specific implementation of this step S703 can refer to the above embodiments, which will not be described here.

[0264] In the above scheme, the network side device configures the total number of sub-indication information in the ECP time slot indication information according to whether the ECP time slot indication information indicates a time slot containing an SSB; and the UE can accurately determine whether the ECP time slot indication information indicates a time slot containing an SSB based on the total number of sub-indication information in the ECP time slot indication information, which can more flexibly perform implicit indication and meet the needs of different application scenarios.

[0265] For the scenario in which the ECP time slot indication information does not indicate a time slot containing an SSB, Figure 8 The interaction flowchart of the sixth ECP time slot determination method provided by the embodiments of the present application is shown in FIG. 6, which can include the following steps. Figure 8

[0266] ​Step S801: For any preset unit length, if the ECP time slot indication information does not indicate a time slot containing an SSB, the network-side device determines, based on the order of the time slots not containing an SSB within the preset unit length and a preset indication rule, a first time slot that can be indicated within the preset unit length from the time slots not containing an SSB within the preset unit length; and determines sub-indication information corresponding to each first time slot within the preset unit length;

[0267] In this embodiment, the above-mentioned preset indication rule is a pre-set indication rule, such as including: which time slot in a preset unit length needs to be indicated. The specific indication rule can be set according to the actual application scenario.

[0268] Exemplarily, the network-side device can determine which time slot can be indicated based on a preset indication rule, and determine the first time slot that can be indicated within the preset unit length according to the order of time slots that do not contain SSB within the preset unit length; and then determine the sub-indication information corresponding to each first time slot (indicating that the corresponding time slot is an ECP time slot, or indicating that the corresponding time slot is not an ECP time slot) according to whether the first time slot is an ECP time slot.

[0269] Step S802: The network side device determines the ECP time slot indication information of the preset unit length based on the sub-indication information corresponding to each first time slot within the preset unit length.

[0270] During implementation, the sub-indication information corresponding to each first time slot within the preset unit length may be combined to obtain the corresponding ECP time slot indication information.

[0271] In some specific implementations, the number of sub-indication information included in the ECP time slot indication information is fixed; however, when the ECP time slot indication information does not indicate a time slot containing an SSB, the first time slot is determined from the time slots not containing an SSB, and the total number of sub-indication information in the ECP time slot indication information of a preset unit length may be greater than the total number of first time slots within the preset unit length. For example, if the ECP time slot indication information of a preset unit length includes 8 sub-indication information, and there are 6 first time slots within the preset unit length, there may be two remaining sub-indication information without corresponding first time slots.

[0272] Based on this, in some optional implementations, if the total number of sub-indication information in the ECP time slot indication information of the preset unit length is greater than the total number of first time slots within the preset unit length, the following steps are further included:

[0273] Determining, according to the order of the first time slots within the next preset unit length, the remaining sub-indication information corresponding to some or all of the first time slots within the next preset unit length; and / or

[0274] According to the order of each second time slot in the preset unit length, determine the remaining sub-indication information corresponding to part or all of the second time slots, and the second time slot is a time slot without SSB in the preset unit length except the first time slot. Taking SCS=15KHz and a radio frame as the preset unit length as an example:

[0275] There are 10 time slots in the preset unit length, which are time slot #0-time slot #9, wherein time slot #1 and time slot #2 are time slots containing SSB, and time slot #3, time slot #4, time slot #5, time slot #8 and time slot #9 are first time slots, and then time slot #0, time slot #6 and time slot #7 are second time slots.

[0276] Still taking the above two remaining sub-indication information as an example:

[0277] The two remaining sub-indication information can indicate the first two first time slots in the next preset unit length;

[0278] The two remaining sub-indication information can also indicate the first two second time slots in the preset unit length, such as time slot #0 and time slot #6 described above;

[0279] One remaining sub-indication information can indicate the first first time slot in the next preset unit length, and the other remaining sub-indication information can indicate the order of the first second time slot in the preset unit length, such as time slot #0 described above.

[0280] In implementation, the sub-indication information corresponding to each first time slot in the preset unit length and the remaining sub-indication information can be combined to obtain corresponding ECP time slot indication information.

[0281] Step S803: The UE determines whether the ECP time slot indication information indicates a time slot containing SSB according to the indication of the network side device.

[0282] The specific implementation of this step S803 can refer to the above embodiments, which will not be described here.

[0283] Step S804: For any preset unit length, if the ECP time slot indication information does not indicate a time slot containing SSB, then according to the order of the time slots without SSB in the preset unit length and the preset indication rule, determine the first time slot that can be indicated in the preset unit length from the time slots without SSB in the preset unit length.

[0284] The UE determines the first time slot that can be indicated in the preset unit length, which is similar to the determination of the network side device, which will not be described here.

[0285] Step S805: The UE determines the sub-indication information corresponding to each first time slot in the preset unit length according to the order of each first time slot in the preset unit length and the ECP time slot indication information of the preset unit length.

[0286] In some embodiments, each first time slot corresponds to sub-indication information, which indicates whether the corresponding first time slot is an ECP time slot or not. Based on this, the UE needs to determine the sub-indication information corresponding to each first time slot in the preset unit length according to the order of each first time slot in the preset unit length and the ECP time slot indication information of the preset unit length.

[0287] As described above, the total number of sub-indication information in the ECP time slot indication information of the preset unit length may be greater than the total number of first time slots in the preset unit length. In this case, in addition to the sub-indication information indicating the first time slots in the preset unit length, the ECP time slot indication information of the preset unit length may also include the remaining sub-indication information indicating the first time slots in the next preset unit length, and / or the sub-indication information indicating the second time slots in the preset unit length.

[0288] Based on this, in some optional embodiments, if the total number of sub-indication information in the ECP time slot indication information of the preset unit length is greater than the total number of first time slots in the preset unit length, the following steps are further included:

[0289] determining the remaining sub-indication information corresponding to part or all of the first time slots in the next preset unit length according to the order of each first time slot in the next preset unit length; and / or

[0290] determining the remaining sub-indication information corresponding to part or all of the second time slots according to the order of each second time slot in the preset unit length, the second time slots being the time slots in the preset unit length excluding the first time slots and not containing SSBs.

[0291] Still taking the above two remaining sub-indication information as an example:

[0292] If the two remaining sub-indication information indicate the first two first time slots in the next preset unit length, the remaining sub-indication information corresponding to the first two first time slots in the next preset unit length is determined.

[0293] If the two remaining sub-indication information indicate the order of the first two second time slots in the preset unit length, the remaining sub-indication information corresponding to the first two second time slots in the preset unit length is determined, such as the time slot #0 and the time slot #6 described above.

[0294] If one of the residual sub-indication information indicates the previous first time slot in the next preset unit length, and another of the residual sub-indication information indicates the previous second time slot in the preset unit length, the residual sub-indication information corresponding to the previous first time slot in the next preset unit length and the residual sub-indication information corresponding to the previous second time slot in the preset unit length are determined, such as the residual sub-indication information corresponding to the time slot #0.

[0295] Step S806: The UE determines the first time slot in the preset unit length as an ECP time slot if the sub-indication information indicates that the corresponding time slot is an ECP time slot.

[0296] As described above, the sub-indication information is used to indicate whether the corresponding first time slot is an ECP time slot or not. For any first time slot in the preset unit length, if the sub-indication information indicates that the corresponding time slot is an ECP time slot, the first time slot can be accurately determined as an ECP time slot.

[0297] In addition, in some optional embodiments described above, there may be residual sub-indication information indicating the second time slots in the preset unit length. Correspondingly, it is also necessary to determine whether the second time slots are ECP time slots based on the residual sub-indication information corresponding to the second time slots.

[0298] In some optional embodiments, the first time slots in the preset unit length and the sub-indication information corresponding to each first time slot are determined in a sequential manner.

[0299] That is, the step S801 described above can be implemented in the following manner:

[0300] The network side device sequentially determines the first time slots that can be indicated in the preset unit length from the time slots without SSBs in the preset unit length according to the order of the time slots without SSBs in the preset unit length and the preset indication rule, and sequentially determines the sub-indication information corresponding to each first time slot in the preset unit length.

[0301] The step S802 described above can be implemented in the following manner:

[0302] The network side device sequentially determines the ECP time slot indication information of the preset unit length based on the sub-indication information corresponding to each first time slot in the preset unit length.

[0303] The step S804 described above can be implemented in the following manner:

[0304] The UE sequentially determines, according to an order of time slots without SSBs in the preset unit length and a preset indication rule, the first time slots in the preset unit length that can be indicated from the time slots without SSBs in the preset unit length.

[0305] The step S805 can be implemented in the following way:

[0306] The UE sequentially determines, according to an order of the first time slots in the preset unit length and the ECP time slot indication information of the preset unit length, the sub-indication information corresponding to each of the first time slots in the preset unit length.

[0307] The following is described with a specific example:

[0308] Taking SCS=15KHz and a radio frame as the preset unit length for example, there are 10 time slots in the preset unit length, which are time slot #0 to time slot #9, and time slot #1 and time slot #2 are time slots with SSBs, the preset indication rule is to indicate the 2nd, 3rd, 4th, 7th, 8th and 9th time slots in the preset unit length, the network side device sequentially determines that the 2nd, 3rd, 4th, 7th and 8th time slots without SSBs in the preset unit length are time slot #3, time slot #4, time slot #5, time slot #8 and time slot #9 respectively, and there is no 9th time slot without SSBs in the preset unit length; the network side device sequentially determines the sub-indication information corresponding to each of time slot #3, time slot #4, time slot #5, time slot #8 and time slot #9 respectively; and determines the ECP time slot indication information of the radio frame based on the sub-indication information corresponding to time slot #3, the sub-indication information corresponding to time slot #4, the sub-indication information corresponding to time slot #5, the sub-indication information corresponding to time slot #8 and the sub-indication information corresponding to time slot #9 in this order. The UE sequentially determines that the 2nd, 3rd, 4th, 7th and 8th time slots without SSBs in the preset unit length are time slot #3, time slot #4, time slot #5, time slot #8 and time slot #9 respectively; and determines the sub-indication information corresponding to each of time slot #3, time slot #4, time slot #5, time slot #8 and time slot #9 respectively.

[0309] The above example is only for illustrating how to determine the first time slots in the preset unit length and the sub-indication information corresponding to each of the first time slots in the order, and the present application is not limited thereto.

[0310] In some other optional embodiments, the first time slots in the preset unit length and the sub-indication information corresponding to each of the first time slots are determined in reverse order.

[0311] The step S801 can be implemented in the following way:

[0312] The network-side device determines, in reverse order, a first time slot that can be indicated in a preset unit length from time slots without SSBs in the preset unit length according to an order of the time slots without SSBs in the preset unit length and a preset indication rule; and determines, in reverse order, sub-indication information corresponding to each first time slot in the preset unit length.

[0313] The step S802 can be implemented in the following manner:

[0314] The network-side device determines, in reverse order, ECP time slot indication information of a preset unit length based on the sub-indication information corresponding to each first time slot in the preset unit length.

[0315] The step S804 can be implemented in the following manner:

[0316] The UE determines, in reverse order, a first time slot that can be indicated in a preset unit length from time slots without SSBs in the preset unit length according to an order of the time slots without SSBs in the preset unit length and a preset indication rule.

[0317] The step S805 can be implemented in the following manner:

[0318] The UE determines, in reverse order, sub-indication information corresponding to each first time slot in a preset unit length according to an order of each first time slot in the preset unit length and ECP time slot indication information of the preset unit length.

[0319] The following is described with reference to a specific example:

[0320] Taking SCS=15KHz and the preset unit length as a wireless frame as an example, there are 10 time slots in the preset unit length, which are recorded as time slot #0 to time slot #9, time slot #1 and time slot #2 are time slots containing SSB, and the preset indication rule is that the 1st to 8th time slots in the preset unit length need to be indicated. The network side device determines in reverse order, and the 1st to 8th time slots in the preset unit length that do not contain SSB are time slot #9, time slot #8, time slot #7, time slot #6, time slot #5, time slot #4, time slot #3 and time slot #0; the network side device is divided The sub-indication information corresponding to time slot #9, time slot #8, time slot #7, time slot #6, time slot #5, time slot #4, time slot #3 and time slot #0 are determined in order; the sub-indication information corresponding to time slot #9, the sub-indication information corresponding to time slot #8, the sub-indication information corresponding to time slot #7, the sub-indication information corresponding to time slot #6, the sub-indication information corresponding to time slot #5, the sub-indication information corresponding to time slot #4, the sub-indication information corresponding to time slot #3 and the sub-indication information corresponding to time slot #0, this order determines the ECP time slot indication information of the wireless frame. The UE determines in reverse order the 1st to 8th time slots within the preset unit length that do not contain SSB, which are time slot #9, time slot #8, time slot #7, time slot #6, time slot #5, time slot #4, time slot #3 and time slot #0; and determines the sub-indication information corresponding to time slot #9, time slot #8, time slot #7, time slot #6, time slot #5, time slot #4, time slot #3 and time slot #0 respectively.

[0321] The above examples are only for illustrating how to determine the first time slot within a preset unit length and the sub-indication information corresponding to each first time slot in a reverse order, and the present application is not limited thereto.

[0322] By determining the first time slot within the preset unit length and the sub-indication information corresponding to each first time slot in reverse order, the network side device can concentrate the sending position of SSB in the first few time slots of the preset unit length, thereby reducing the impact of the network side device deploying SSB on the ECP time slot indication.

[0323] For the scenario where the ECP time slot indication information indicates a time slot containing SSB, Figure 9 The interactive flow chart of the seventh ECP time slot determination method provided in the embodiment of the present application is as follows: Figure 9 As shown, this may include:

[0324] Step S901: For any preset unit length, if the ECP time slot indication information indicates a time slot containing SSB, the network side device determines the first time slot that can be indicated within the preset unit length from all the time slots within the preset unit length according to the order of all time slots within the preset unit length and the preset indication rule; and determines the sub-indication information corresponding to each first time slot within the preset unit length.

[0325] The preset indication rule can refer to the above embodiments.

[0326] For example, the network side device can determine the time slots that can be indicated based on the preset indication rule, determine the first time slot that can be indicated in the preset unit length according to the order of all time slots in the preset unit length, and then determine the sub-indication information corresponding to each first time slot according to whether the first time slot is an ECP time slot (indicating that the corresponding time slot is an ECP time slot or indicating that the corresponding time slot is not an ECP time slot).

[0327] Step S902: The network side device determines the ECP time slot indication information of the preset unit length based on the sub-indication information corresponding to each first time slot in the preset unit length.

[0328] Step S903: The UE determines whether the ECP time slot indication information indicates a time slot containing an SSB according to the indication of the network side device.

[0329] The specific implementation of steps S902-S903 can refer to the above embodiments, which will not be repeated here.

[0330] Step S904: For any preset unit length, if the ECP time slot indication information indicates a time slot containing an SSB, the UE determines the first time slot that can be indicated in the preset unit length from all time slots in the preset unit length according to the order of all time slots in the preset unit length and the preset indication rule.

[0331] The UE determines the first time slot that can be indicated in the preset unit length, which is similar to the determination of the network side device, which will not be repeated here.

[0332] Step S905: The UE determines the sub-indication information corresponding to each first time slot in the preset unit length according to the order of each first time slot in the preset unit length and the ECP time slot indication information of the preset unit length.

[0333] Step S906: For any first time slot in the preset unit length, if the sub-indication information indicates that the corresponding time slot is an ECP time slot, the UE determines the first time slot as an ECP time slot.

[0334] The specific implementation of steps S905-S906 can refer to the above embodiments, which will not be repeated here.

[0335] For the scenario where the ECP time slot indication information indicates a time slot containing an SSB, the first time slot in the preset unit length and the sub-indication information corresponding to each first time slot can also be determined in a sequential or reverse order manner. The specific implementation can refer to the above embodiments, which will not be repeated here.

[0336] In some embodiments, for the scenario where the ECP slot indication information indicates a slot containing SSB, the slot containing SSB can be indicated as an ECP slot. Since SSB needs to be transmitted using NCP, when the slot containing SSB is indicated as an ECP slot, only part of the position symbols in the slot are ECP position symbols.

[0337] Based on this, in some optional embodiments, if the ECP slot indication information indicates a slot containing SSB, and it is determined that the slot containing SSB is an ECP slot, after step S902, the method further includes:

[0338] The network side device determines the position symbols belonging to NCP based on the SSB position symbols in the slot containing SSB.

[0339] Correspondingly, after step S906, the method further includes:

[0340] The UE determines the position symbols belonging to NCP based on the SSB position symbols in the slot containing SSB.

[0341] Referring to Figure 10A As shown in FIG. 6, one NCP slot contains 14 NCP position symbols;

[0342] Referring to Figure 10B As shown in FIG. 7, one ECP slot contains 12 ECP position symbols.

[0343] The above determination of the position symbols belonging to NCP based on the SSB position symbols in the slot containing SSB can be implemented by, but not limited to, the following ways:

[0344] 1) The SSB position symbols in the slot containing SSB are determined as the position symbols belonging to NCP. For example:

[0345] The SSB position symbols in the slot containing SSB are position symbol #8 to position symbol #11, and position symbol #8 to position symbol #11 are determined as the position symbols belonging to NCP.

[0346] 2) All position symbols in the half slot where the SSB position symbols in the slot containing SSB are located are determined as the position symbols belonging to NCP. For example:

[0347] The SSB position symbols in the slot containing SSB are position symbol #8 to position symbol #11, there are 14 NCP position symbols or 12 ECP position symbols in one slot, the last 7 position symbols are determined as the position symbols belonging to NCP, and the first 6 position symbols are determined as the position symbols belonging to ECP.

[0348] The above two manners are only illustrative, and other manners can be used to determine the position symbols belonging to the NCP in implementation.

[0349] In addition, in addition to the SSB needing to be transmitted by using the NCP, the PDCCH of the system broadcast message also needs to be transmitted by using the NCP, and therefore, when the time slot containing the SSB is indicated as the ECP time slot, some of the position symbols are the position symbols belonging to the NCP for transmitting the PDCCH of the system broadcast message.

[0350] In some optional embodiments, based on the SSB position symbol in the time slot containing the SSB, the position symbol belonging to the NCP is determined, and the method further includes:

[0351] The position symbol of the PDCCH of the system broadcast message needing to be transmitted in the time slot containing the SSB is determined as the position symbol belonging to the NCP.

[0352] By scheduling the PDSCH or transmitting the PDCCH by using the ECP symbol, better compatibility with the unicast design of the NR can be achieved.

[0353] Figure 11 An interaction flowchart of an eighth ECP time slot determination method provided by the embodiments of the present application is shown in FIG. 8, and can include the following steps. Figure 11

[0354] Step S1101: The network side device determines the time slot containing the SSB and / or the time slot not containing the SSB in the preset unit length.

[0355] As described above, in some scenarios, the ECP time slot indication information does not indicate the time slot containing the SSB, and the first time slot needs to be determined from the time slot not containing the SSB in the preset unit length; in some scenarios, the ECP time slot indication information indicates the time slot containing the SSB, and the time slot containing the SSB is the ECP time slot, and the position symbol belonging to the NCP in the time slot containing the SSB needs to be determined. Based on this, the network side device and the UE need to determine the time slot containing the SSB and / or the time slot not containing the SSB in the preset unit length.

[0356] Still taking the SCS=15KHz and the preset unit length being one radio frame as an example, according to the above Figures 2A-2C It can be known that there are at most 8 candidate positions for transmitting the SSB in one radio frame, and the network side device can indicate whether the SSB is transmitted at each candidate position by using the inOneGroup value in the SSB position parameter ssb-PositionsInBurst. Refer to Figure 12 ​As shown, the network-side device uses the 8-bit indication (B0~B8) of inOneGroup, and the inOneGroup value of 0 indicates that no SSB is sent in the corresponding candidate position, and the inOneGroup value of 1 indicates that SSB is sent in the corresponding candidate position.

[0357] It can be understood that the above inOneGroup value is only an example, when the inOneGroup value is 1, it can also indicate that no SSB is sent in the corresponding candidate position; when the inOneGroup value is 0, it can also indicate that SSB is sent in the corresponding candidate position; or inOneGroup can also be configured as other values, which is not limited in the present application, and can be configured according to the actual application scene.

[0358] In addition, the network-side device can also indicate the transmission period of the SSB burst block through the SSB period parameter (ssb-PeriodicityServingCell) of the serving cell, and the transmission period can be 5ms, 10ms, 20ms, 40ms, 80ms or 160ms, etc.

[0359] Step S1102: The network-side device sends the preset unit length of ECP slot indication information to the UE according to whether the ECP slot indication information indicates a slot containing SSB.

[0360] Step S1103: The UE determines whether the ECP slot indication information indicates a slot containing SSB according to the indication of the network-side device.

[0361] The specific implementation of steps S1102-S1103 can be referred to the above embodiments, which will not be repeated here.

[0362] Step S1104: The UE determines the slot containing SSB and / or the slot not containing SSB in the preset unit length.

[0363] As described above, the network-side device can indicate whether SSB is sent in each candidate position through the inOneGroup value in the SSB position parameter ssb-PositionsInBurst, and correspondingly, the UE determines whether SSB is sent in each candidate position based on the inOneGroup value in the SSB position parameter ssb-PositionsInBurst.

[0364] Step S1105: The UE determines the ECP slot in the preset unit length sent by the network-side device according to the determination result of whether the ECP slot indication information indicates a slot containing SSB and the ECP slot indication information.

[0365] The specific implementation of this step S1105 can refer to the above embodiments, which will not be repeated here.

[0366] The following will be described in detail with three specific examples.

[0367] Embodiment 1

[0368] The network side device sends high layer signaling to the UE, such as a system broadcast message transmitted through a broadcast control channel, a broadcast multicast configuration message transmitted through a multicast control channel, a radio link control message based on the UE, or a control message based on a media access layer. Refer to the above Figure 4 、 Figure 5 As shown in the above, the high layer signaling contains configuration information, and the UE determines whether the ECP slot indication information indicates a slot containing SSB according to the configuration information; or the high layer information does not contain configuration information, and the UE determines whether the ECP slot indication information indicates a slot containing SSB based on a default rule. The specific implementation of this step can refer to the above Figure 4 and Figure 5 embodiments, which will not be repeated here.

[0369] The UE obtains the inOneGroup value in the SSB position parameter ssb-PositionsInBurst transmitted by the network side device based on the system broadcast message, and determines whether the corresponding candidate position transmits SSB based on the inOneGroup value. In this embodiment, the SCS is 15KHz, and the preset unit length is one radio frame. Refer to Figure 12 As shown in the above, the network side device uses 8-bit indication (B0-B8) of inOneGroup, and the inOneGroup value of 0 indicates that the corresponding candidate position does not transmit SSB, and the inOneGroup value of 1 indicates that the corresponding candidate position transmits SSB. Refer to Figure 13A As shown in the above, in this embodiment, the inOneGroup values of candidate position #3 and candidate position #4 are 1, and the inOneGroup values of the remaining candidate positions are 0, candidate position #3 and candidate position #4 transmit SSB, so that slot #1 and slot #2 are slots containing SSB; slot #0, slot #3, slot #4, slot #5, slot #6, slot #7, slot #8 and slot #9 are slots not containing SSB.

[0370] In this embodiment, the preset indication rule is to indicate the 2nd, 3rd, 4th, 7th, 8th and 9th slots in the preset unit length, the first slot in the preset unit length, and the sub-indication information corresponding to each first slot are all determined in a sequential manner.

[0371] If the ECP slot indication information does not indicate the slot containing SSB, the slot containing SSB needs to be skipped (i.e., the slot #1 and the slot #2 are skipped), after skipping the slot #1 and the slot #2, the 2nd, 3rd, 4th, 7th and 8th slots not containing SSB are the slot #3, the slot #4, the slot #5, the slot #8 and the slot #9 respectively, i.e., the five slots are the first slots that can be indicated, and there is no 9th slot not containing SSB in the preset unit length; in addition, the slot #0, the slot #6 and the slot #7 are the second slots not containing SSB except the first slots. Referring to Figure 13B As shown in the figure, b0 in the ECP slot indication information indicates whether the slot #3 is an ECP slot, b1 indicates whether the slot #4 is an ECP slot, b2 indicates whether the slot #5 is an ECP slot, b3 indicates whether the slot #8 is an ECP slot, b4 indicates whether the slot #9 is an ECP slot, and b5 has no corresponding first slot.

[0372] In some scenarios, b5 can indicate the first second slot in the above wireless frame, i.e., the slot #0; in some other scenarios, b5 can indicate the first first slot in the next wireless frame.

[0373] If the ECP slot indication information indicates the slot containing SSB, the slot containing SSB does not need to be skipped, and among all the slots in the wireless frame, the 2nd, 3rd, 4th, 7th, 8th and 9th slots are the slot #1, the slot #2, the slot #3, the slot #6, the slot #7 and the slot #8 respectively, i.e., the six slots are the first slots that can be indicated. Referring to Figure 13C As shown in the figure, b0 in the ECP slot indication information indicates whether the slot #1 is an ECP slot, b1 indicates whether the slot #2 is an ECP slot, b2 indicates whether the slot #3 is an ECP slot, b3 indicates whether the slot #6 is an ECP slot, b4 indicates whether the slot #7 is an ECP slot, and b5 indicates whether the slot #8 is an ECP slot.

[0374] Since SSB still needs to be transmitted using NCP, when the above slot #1 and the slot #2 are ECP slots, only part of the position symbols are ECP position symbols. Referring to Figure 13D As shown in the figure, in the slot #1, the SSB position symbols are NCP position symbols #8-#11, at least the time domain positions of these position symbols cannot be ECP, and the next 7 position symbols (NCP position symbols #7-NCP position symbols #13) are determined as the position symbols belonging to NCP; in addition, the ECP position symbols #0-#5 of the ECP slot can use ECP symbols to schedule PDSCH. Referring to Figure 13EAs shown, in the time slot #2, the SSB position symbols are the NCP position symbol #2~the NCP position symbol #5, and the time domain positions of at least these several position symbols cannot be ECP. The first 7 position symbols (the NCP position symbol #0~the NCP position symbol #6) are determined as the position symbols belonging to NCP. In addition, the ECP position symbol #6~the ECP position symbol #11 of the ECP time slot can use the ECP symbol to schedule the PDSCH.

[0375] In the actual application, the preset unit length can also be other lengths, such as 5 ms (5 time slots when SCS=15 KHz), or 20 ms (20 time slots when SCS=15 KHz), or 4 ms (4 time slots when SCS=15 KHz). In the embodiment 1, the ECP time slot indication information contains 6 sub-indication information as an example, and in the actual application, the ECP time slot indication information can contain more or less sub-indication information, such as 5, 10, or 8, etc. In the embodiment 1, the position symbols belonging to ECP in the ECP time slot containing SSB are only illustrative, and the present application is not limited thereto.

[0376] Embodiment 2

[0377] If the network side device determines that the ECP time slot indication information indicates a time slot containing SSB, the network side device configures the ECP time slot indication information with a total number of sub-indication information greater than the first preset number; otherwise, the network side device configures the ECP time slot indication information with a total number of sub-indication information not greater than the first preset number. The specific implementation of this step can refer to the above Figure 6 Embodiment, which will not be repeated here.

[0378] The UE obtains the inOneGroup value in the SSB position parameter ssb-PositionsInBurst sent by the network side device based on the system broadcast message, and determines whether the corresponding candidate position transmits SSB based on the inOneGroup value. In this embodiment, SCS=15 KHz, and the preset unit length is one radio frame. Referring to Figure 12 As shown, the network side device uses 8-bit indication (B0~B8) of inOneGroup, and the inOneGroup value of 0 indicates that the corresponding candidate position does not transmit SSB, and the inOneGroup value of 1 indicates that the corresponding candidate position transmits SSB. Referring to Figure 14AAs shown, in this embodiment, the inOneGroup values corresponding to candidate position #2 and candidate position #5 are 1, and the inOneGroup values corresponding to the other candidate positions are 0. Candidate position #2 and candidate position #5 send SSBs, and therefore time slot #1 and time slot #2 are SSB-containing time slots; time slot #0, time slot #3, time slot #4, time slot #5, time slot #6, time slot #7, time slot #8, and time slot #9 are SSB-non-containing time slots.

[0379] In this embodiment, the first time slots in a preset unit length and the sub-indication information corresponding to each first time slot are determined in reverse order. The first preset number is 8, the total number of sub-indication information in the ECP time slot indication information is greater than 8, and the ECP time slot indication information indicates time slots containing SSBs. The total number of sub-indication information in the ECP time slot indication information is less than or equal to 8, and the ECP time slot indication information does not indicate time slots containing SSBs.

[0380] Suppose that the preset indication rule is to indicate the 1st to 8th time slots in a preset unit length, the total number of sub-indication information in the ECP time slot indication information is equal to 8, the ECP time slot indication information does not indicate time slots containing SSBs, and the time slots containing SSBs need to be skipped (i.e., time slot #1 and time slot #2 are skipped). After skipping time slot #1 and time slot #2, the 1st to 8th time slots not containing SSBs are time slot #9, time slot #8, time slot #7, time slot #6, time slot #5, time slot #4, time slot #3, and time slot #0, respectively. See Figure 14B As shown, b0 in the ECP time slot indication information indicates whether time slot #9 is an ECP time slot, b1 indicates whether time slot #8 is an ECP time slot, b2 indicates whether time slot #7 is an ECP time slot, b3 indicates whether time slot #6 is an ECP time slot, b4 indicates whether time slot #5 is an ECP time slot, b5 indicates whether time slot #4 is an ECP time slot, b6 indicates whether time slot #3 is an ECP time slot, and b7 indicates whether time slot #0 is an ECP time slot.

[0381] Suppose that the preset indication rule is to indicate the 1st to 10th time slots in a preset unit length, the total number of sub-indication information in the ECP time slot indication information is greater than 8, and the ECP time slot indication information indicates time slots containing SSBs. The time slots containing SSBs do not need to be skipped, and among all the time slots in the radio frame, the 1st to 10th time slots are time slot #9, time slot #8, time slot #7, time slot #6, time slot #5, time slot #4, time slot #3, time slot #2, time slot #1, and time slot #0, respectively. See Figure 14CAs shown, b0 in the ECP slot indication information indicates whether slot #9 is an ECP slot, b1 indicates whether slot #8 is an ECP slot, b2 indicates whether slot #7 is an ECP slot, b3 indicates whether slot #6 is an ECP slot, b4 indicates whether slot #5 is an ECP slot, b5 indicates whether slot #4 is an ECP slot, b6 indicates whether slot #3 is an ECP slot, b7 indicates whether slot #2 is an ECP slot, b8 indicates whether slot #1 is an ECP slot, and b9 indicates whether slot #0 is an ECP slot.

[0382] Since the SSB still needs to be transmitted using NCP, only part of the position symbols are ECP position symbols when slot #1 and slot #2 are ECP slots. Referring to Figure 14D As shown, in slot #1, the SSB position symbols are NCP position symbols #2-#5, and the position symbols of the PDCCH that needs to transmit the system broadcast message are NCP position symbols #6 and #7, and NCP position symbols #0-#7 are determined as NCP position symbols; in addition, ECP position symbols #7-#11 of the ECP slot can be used to schedule PDSCH using ECP symbols. Referring to Figure 14E As shown, in slot #2, the SSB position symbols are NCP position symbols #8-#11, and the position symbols of the PDCCH that needs to transmit the system broadcast message are NCP position symbols #6 and #7, and NCP position symbols #6-#13 are determined as NCP position symbols; in addition, ECP position symbols #0-#4 of the ECP slot can be used to schedule PDSCH using ECP symbols.

[0383] In Embodiment 2, the preset unit length is one radio frame, but in actual applications, the preset unit length can also be other lengths, such as 5 ms (5 slots when SCS is 15 KHz), or 20 ms (20 slots when SCS is 15 KHz), or 4 ms (4 slots when SCS is 15 KHz); in Embodiment 2, the ECP slot indication information contains 8 sub-indication information or 10 sub-indication information, but in actual applications, the ECP slot indication information can contain more or less sub-indication information, such as 5, 6, or 7, etc.; in Embodiment 2, the ECP position symbols in the ECP slot containing SSB are only illustrative, and the present application is not limited thereto.

[0384] Embodiment 3

[0385] If the network side device determines that the ECP time slot indication information indicates a time slot containing SSB, it configures the first ECP time slot indication information that does not indicate a time slot containing SSB, and the second ECP time slot indication information that indicates a time slot containing SSB, corresponding to the preset unit length; and after sending the first ECP time slot indication information to the UE, it sends the second ECP time slot indication information to the UE; if it is determined that the ECP time slot indication information does not indicate a time slot containing SSB, it configures an ECP time slot indication information corresponding to the preset unit length. The specific implementation method of this step can refer to the above Figure 7 The embodiments will not be described in detail here.

[0386] Based on the system broadcast message, the UE obtains the inOneGroup value in the SSB position parameter ssb-PositionsInBurst sent by the network side device, and determines whether to send SSB at the corresponding candidate position based on the inOneGroup value. In this embodiment, SCS = 15KHz, and the preset unit length is one radio frame. Figure 12 As shown, the network side device uses the 8-bit indication (B0 to B8) of inOneGroup. The inOneGroup value of 0 indicates that the corresponding candidate position does not send SSB, and the inOneGroup value of 1 indicates that the corresponding candidate position sends SSB. Figure 15A As shown, in this embodiment, the inOneGroup value corresponding to candidate position #0, candidate position #1, candidate position #3 and candidate position #4 is 1, and the inOneGroup value corresponding to the remaining candidate positions is 0. Candidate position #0, candidate position #1, candidate position #3 and candidate position #4 send SSB, so time slot #0, time slot #1 and time slot #2 are time slots containing SSB; time slot #3, time slot #4, time slot #5, time slot #6, time slot #7, time slot #8 and time slot #9 are time slots that do not contain SSB.

[0387] In this embodiment, the first time slot within the preset unit length and the sub-indication information corresponding to each first time slot are determined in a sequential manner; the network side device is configured with the first ECP time slot indication information corresponding to the preset unit length that does not indicate the time slot containing SSB, and the second ECP time slot indication information that indicates the time slot containing SSB, wherein the first ECP time slot indication information includes 6 sub-indication information and the second ECP time slot indication information includes 4 sub-indication information.

[0388] If the indication rule corresponding to the first ECP time slot indication information is that the 1st-6th time slots in a preset unit length need to be indicated, the first ECP time slot indication information does not indicate the time slots containing SSB, and the time slots containing SSB need to be skipped (i.e., time slot #0, time slot #1, and time slot #2 are skipped), after skipping time slot #0, time slot #1, and time slot #2, the 1st-6th time slots not containing SSB are time slot #3-time slot #8, respectively. See Figure 15B As shown in the table, b0 in the ECP time slot indication information indicates whether time slot #3 is an ECP time slot, b1 indicates whether time slot #4 is an ECP time slot, b2 indicates whether time slot #5 is an ECP time slot, b3 indicates whether time slot #6 is an ECP time slot, b4 indicates whether time slot #7 is an ECP time slot, and b5 indicates whether time slot #8 is an ECP time slot.

[0389] If the indication rule corresponding to the second ECP time slot indication information is that the 1st-4th time slots in a preset unit length need to be indicated, the second ECP time slot indication information indicates the time slots containing SSB, and the time slots containing SSB do not need to be skipped, of all the time slots in the radio frame, the 1st-4th time slots other than the time slots (time slot #3-time slot #8) indicated by the first ECP time slot indication information are time slot #0, time slot #1, time slot #2, and time slot #9, respectively. See Figure 15C As shown in the table, b0 in the ECP time slot indication information indicates whether time slot #0 is an ECP time slot, b1 indicates whether time slot #1 is an ECP time slot, b2 indicates whether time slot #2 is an ECP time slot, and b3 indicates whether time slot #9 is an ECP time slot.

[0390] Since SSB still needs to be transmitted using NCP, the above-mentioned time slot #0 can only be an NCP time slot, and when the above-mentioned time slot #1 and time slot #2 are ECP time slots, only part of the position symbols are ECP position symbols. See Figure 15D As shown in the table, in time slot #1, the SSB position symbols are NCP position symbols #8-NCP position symbols #11, and the position symbols of the PDCCH that need to transmit system broadcast messages are NCP position symbols #6 and NCP position symbols #7, NCP position symbols #6-NCP position symbols #13 are determined as position symbols belonging to NCP; in addition, ECP position symbols #0-ECP position symbols #4 of the ECP time slot can be used to schedule PDSCH using ECP symbols. See Figure 15E As shown in the table, in time slot #2, the SSB position symbols are NCP position symbols #2-NCP position symbols #5, and the position symbols of the PDCCH that need to transmit system broadcast messages are NCP position symbols #6 and NCP position symbols #7, NCP position symbols #0-NCP position symbols #7 are determined as position symbols belonging to NCP; in addition, ECP position symbols #7-ECP position symbols #11 of the ECP time slot can be used to schedule PDSCH using ECP symbols.

[0391] The preset unit length in the embodiment 3 is one radio frame, but in actual application, the preset unit length can also be other lengths, such as 5 ms (5 time slots when SCS is 15 KHz), or 20 ms (20 time slots when SCS is 15 KHz), or 4 ms (4 time slots when SCS is 15 KHz); the ECP time slot indication information in the embodiment 3 contains 6 sub-indication information and 4 sub-indication information, but in actual application, the ECP time slot indication information can contain more or less sub-indication information; the position symbol belonging to the ECP in the ECP time slot containing SSB in the embodiment 3 is only an example, and the application is not limited thereto.

[0392] The embodiments 1-3 above support the ECP time slot containing the NCP position symbol, and improve the transmission efficiency of the ECP time slot, which can be improved from 60% to 97.5% (only 0.5 time slots do not transmit broadcast data in 20 time slots of 20 ms).
