[0057] To facilitate understanding, the relevant technologies and concepts involved in the embodiments of this application will be introduced first.
[0058] I. LPWA Terminal
[0059] With the imminent deployment of 6G and the approaching end of the lifespan of existing cellular IoT devices, such as NB-IoT devices, 6G presents an opportune time to deploy a new generation of higher-performance, lower-cost, and larger-scale LPWA devices. The LPWA market is expected to experience strong growth with the launch of 6G, penetrating a wide variety of application scenarios, such as logistics management, smart homes, and smart cities.
[0060] In related technologies, 4G LPWA solutions, such as NB-IoT and eMBB, are not well compatible. The physical layers of NB-IoT user equipment and eMBB user equipment differ significantly, increasing both the standardization workload and the cost of NB-IoT user equipment. Furthermore, NB-IoT user equipment requires dedicated NB-IoT base stations, increasing network deployment costs and operational efficiency. As shown in Figure 1b, eMBB user equipment interacts with eMBB base stations, while NB-IoT user equipment interacts with NB-IoT base stations. When designing 6G LPWA solutions, these shortcomings need to be addressed. 6G LPWA and eMBB should be as compatible as possible, especially at the physical layer, where LPWA should reuse eMBB design as much as possible. This means organically integrating 6G LPWA and eMBB, dynamically and efficiently serving both eMBB user equipment and a large number of LPWA user equipment simultaneously through a single 6G base station, as shown in Figure 1c.
[0061] In one embodiment, the LPWA terminal has at least one of the following capabilities limited compared to a normal capability terminal (eMBB terminal):
[0062] Transmission bandwidth capability;
[0063] Radio frequency (RF) capability;
[0064] Transmission power capability;
[0065] Error detection, demodulation / decoding capabilities.
[0066] The information receiving method, sending method, apparatus, terminal, and network-side device provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.
[0067] Please refer to Figure 2, which is a flowchart of an information receiving method provided in an embodiment of this application. As shown in Figure 2, it includes the following steps:
[0068] Step 201: The first terminal receives first information, wherein the first information includes at least one of the following: a first physical control channel and a master information block (MIB).
[0069] In one embodiment, the first terminal may be an LPWA terminal or other terminals, such as a normally capable terminal. In some embodiments, the first terminal may also be an eMBB terminal.
[0070] The aforementioned "first terminal receiving first information" refers to the terminal receiving the first information sent by the network-side device.
[0071] The aforementioned first piece of information can be used to schedule system information blocks.
[0072] In some implementations, the first information is a first physical control channel or a master information block, or the first information includes both a first physical control channel and a master information block.
[0073] In some implementations, the first information may be carried by the first physical control channel, or by the main information block, or by both the first physical control channel and the main information block.
[0074] The aforementioned first physical control channel can be the physical downlink control channel (PDCCH).
[0075] In some implementations, the downlink control information carried by the first physical control channel is scrambled by a specific Radio Network Temporary Identifier (RNTI), or the first physical control channel is located in a specific time-frequency domain.
[0076] The aforementioned main information block can also be used to provide at least one of the following: timing information, community access information, etc.
[0077] Step 202: The first terminal receives the information from the first information receiving system information block, which is used to provide relevant information about cell camping or initial access.
[0078] In another embodiment, the system information block may also be used for information such as network configuration of other functions, which is not limited here.
[0079] In some implementations, the aforementioned system information block may be System Information Block (SIB) 1 or other SIBs, and there is no limitation thereto.
[0080] The information related to cell camping or initial access mentioned above may include, for example, Random Access Channel (RACH) configuration information.
[0081] The aforementioned first terminal receiving system information blocks based on the first information may involve the first terminal obtaining scheduling information or scheduling-related information of the system information block based on the first information, and then receiving the system information block based on the scheduling information or scheduling-related information; or, the aforementioned first terminal determining the time-frequency domain position of the system information block based on the time-frequency domain position of the first information, and then receiving the system information block.
[0082] In this embodiment, since the first information includes at least one of a first physical control channel and a main information block, the system information block can be received based on at least one of the first physical control channel and the main information block, thereby determining the method by which the terminal receives the system information block and improving the reliability of the terminal receiving the system information block. Furthermore, since the system information block is used to provide information related to cell camping or initial access, the terminal can more easily obtain this information, enabling it to better perform cell camping or initial access and thus improving its communication performance.
[0083] As an optional implementation, the first information is repeatedly transmitted within a first time period, and the system information block is repeatedly transmitted within a second time period.
[0084] The first time period mentioned above can be one or more time periods, which can be agreed upon by the protocol or configured by the network-side device, and the number of repetitions can also be agreed upon by the protocol or configured by the network-side device.
[0085] In the case where the aforementioned first information includes a first physical control channel and a master information block, the first physical control channel and the master information block can be repeatedly transmitted within their respective associated first time periods.
[0086] The aforementioned second time period can be one or more time periods, which can be agreed upon by the protocol or configured by the network-side device, and the number of repetitions can also be agreed upon by the protocol or configured by the network-side device.
[0087] Since the first information is repeatedly transmitted in the first time period and the system information block is repeatedly transmitted in the second time period, the terminal can more easily receive the system information block, thereby further improving the reliability of the terminal receiving the system information block.
[0088] In some implementations, when the first information includes the main information block, the system information block and the main information block satisfy at least one of the following:
[0089] Within the first time period, the transmission of each main information block is associated with the same number of repeated transmissions of the system information block, or within the first time period, the transmission of each main information block is associated with different numbers of repeated transmissions of the system information block.
[0090] During the first time period, the transmission of each of the main information blocks is associated with at least one repeated transmission of the system information block;
[0091] The first time period is less than or equal to the second time period.
[0092] The repeated transmission of the system information block associated with the transmission of each master information block within the first time period refers to the same number of times the system information block corresponding to each master information block is transmitted within the first time period. For example, the number of times the system information block is scheduled for each master information block is the same, such as scheduling the system information block once or twice for each master information block.
[0093] The aforementioned repeated transmission of the system information block associated with the transmission of each master information block within the first time period refers to the different number of times the system information block corresponding to each master information block is transmitted within the first time period. For example, the number of times the system information block is scheduled by each master information block is different, such as one master information block scheduling the system information block once, and another master information block scheduling the system information block twice.
[0094] The above-mentioned transmission of each main information block associated with at least one repeated transmission of the system information block within the first time period means that each transmission of the main information block within the first time period can be associated with one or more transmissions of the system information blocks, such as each transmission of the main information block can schedule one or more transmissions of the system information blocks.
[0095] At least one of the above methods can support flexible scheduling and transmission of system information blocks, and can save transmission overhead when associating multiple system information blocks. Taking the first information as SIB or MIB and the system information block as SIB1 as an example, as shown in Figure 3, one first information can schedule the transmission of one or more system information blocks.
[0096] The first time period mentioned above is less than or equal to the second time period, which allows for the transmission of system information blocks over a longer period of time, thereby improving the reliability of system information block transmission.
[0097] In some implementations, the corresponding first information and the system information block are transmitted within the same time unit, or the corresponding first information and the system information block are separated by a second time interval; wherein, in the corresponding first information and the system information block, the first information is used to schedule the system information block;
[0098] Alternatively, the start time of the first transmission of the system information block in the second time period or the first time period may be an interval of a first time interval between the start time of the second time period and the first end time, wherein the first end time includes: the end time of the last repeated transmission of the first information in the first time period, or the end time of the first time period.
[0099] The aforementioned time unit can be a time slot, a sub-time slot, or other time unit.
[0100] The first information and the system information block mentioned above refer to the first information being used to schedule the system information block.
[0101] Since the corresponding first information and the system information block are transmitted within the same time unit, the first terminal can receive the system information block more efficiently. For example, taking the first information as PDCCH and the system information block as SIB1 as an example, as shown in Figure 4, the first information and the system information block are transmitted within the same time unit.
[0102] The first and second time intervals mentioned above can be agreed upon by the protocol or configured by the network-side equipment.
[0103] Since the first information and the system information block are spaced apart by a second time interval, the first terminal has enough time to process the first information after receiving it, which in turn makes it easier for the terminal to receive the system information block.
[0104] Since the system information block is first transmitted at the start time of the second time period or the start time of the second time period is separated from the first end time by a first time interval, the first terminal has enough time to process and merge one or more first information transmissions after receiving the first information, which helps the terminal to easily receive the system information block. For example, taking the first information as PDCCH and the system information block as SIB1 as an example, as shown in Figure 5, the system information block is transmitted after the first information is transmitted.
[0105] As an optional implementation, the first terminal has a first terminal feature, or the first terminal has a first terminal feature and a second terminal feature.
[0106] The terminal features are determined based on at least one of the following: bandwidth information supported by the terminal, bandwidth information during terminal operation, coverage information, power consumption information, energy saving information, terminal type information, terminal operating mode information, radio frequency capability, baseband processing capability, transmit power capability, demodulation capability, and decoding capability.
[0107] The terminal capability corresponding to the first terminal feature is limited, or the terminal capability corresponding to the first terminal feature is lower than the terminal capability corresponding to the second terminal feature.
[0108] The above-mentioned terminal features are determined based on at least one of the above features, which can be understood as: the above-mentioned first terminal feature is determined based on at least one of the above features, and the above-mentioned second terminal feature is determined based on at least one of the above features.
[0109] The terminal features in this application embodiment can be understood as a single feature or a combination of features. The terminal features can be determined based on at least one of the following: the bandwidth information supported by the terminal, the bandwidth information of the terminal operation, the coverage information, the power consumption information, the energy saving information, the terminal type information, and the terminal operating mode information.
[0110] The terminal receives the first information (including determining the time-frequency domain resources where the first information is located) based on its own terminal characteristics. For example, since the time-frequency domain resources or other receiving parameters corresponding to the first information are different for different terminal characteristics, the terminal receives the corresponding first information based on its own characteristics.
[0111] After receiving the first information from the network-side device, the terminal can determine the time-frequency domain resources of the system information block based on the first information and the terminal characteristics of the terminal. For example, the time-frequency domain resources of the first information and / or system information block are different for terminals with different terminal characteristics.
[0112] The aforementioned first terminal possessing both first terminal and second terminal characteristics can be understood as the aforementioned first terminal possessing both of these characteristics. For example, an eMBB terminal (e.g., a mobile phone) possesses the characteristics of a normal terminal and also the characteristics of an LPWA terminal.
[0113] The terminal capability limitation corresponding to the first terminal feature mentioned above may be at least one of the following: transmission bandwidth, radio frequency capability, baseband processing capability, transmit power capability, demodulation capability, decoding capability, etc.
[0114] The terminal capabilities corresponding to the different terminal characteristics mentioned above can be different.
[0115] The terminal capability corresponding to the first terminal feature mentioned above is lower than the terminal capability corresponding to the second terminal feature. This can be due to at least one of the following: transmission bandwidth, radio frequency capability, baseband processing capability, transmit power capability, demodulation capability, or decoding capability corresponding to the first terminal feature being lower than the terminal capability corresponding to the second terminal feature. For example, the transmission bandwidth, radio frequency capability, baseband processing capability, transmit power capability, demodulation capability, and decoding capability of the terminal with the first terminal feature are lower than those of the terminal with the second terminal feature.
[0116] In the above embodiments, since the first terminal possesses the first terminal characteristics, the terminal possessing the first terminal characteristics can receive the system information block based on the above method, thereby improving the receiving capability of the terminal with those characteristics. Similarly, since the first terminal possesses both the first terminal characteristics and the second terminal characteristics, the terminal possessing both the first terminal characteristics and the second terminal characteristics can receive the system information block based on the above method, thereby improving the receiving capability of the terminal with those characteristics.
[0117] In one embodiment, if a terminal possesses both a first terminal feature and a second terminal feature, the two terminal features cannot be applied simultaneously.
[0118] As an optional implementation, at least a portion of the resources or content carried by the first physical control channel are shared between a terminal possessing the first terminal characteristics and a terminal possessing the second terminal characteristics; and / or
[0119] At least a portion of the resources or content carried by the main information block are shared by a terminal possessing the first terminal characteristic and a terminal possessing the second terminal characteristic; and / or
[0120] At least a portion of the resources or content carried by the system information block are shared by a terminal possessing the first terminal characteristic and a terminal possessing the second terminal characteristic; and / or
[0121] At least a portion of the resources or content carried by at least one of the physical shared channels carrying the main information block are shared between a terminal having the first terminal characteristic and a terminal having the second terminal characteristic.
[0122] It should be noted that, optionally, compared to a terminal with the first terminal feature, a terminal with the second terminal feature has no limitations on its terminal capabilities; that is, a terminal with the second terminal feature can be understood as a terminal with normal capabilities.
[0123] The fact that at least a portion of the resources or content carried by the aforementioned first physical control channel are shared by a terminal possessing the first terminal characteristic and a terminal possessing the second terminal characteristic can be understood as meaning that these at least a portion of the resources or the content carried by the first physical control channel are sent to the terminal possessing the first terminal characteristic and the terminal possessing the second terminal characteristic. That is, the terminal possessing the first terminal characteristic and the terminal possessing the second terminal characteristic can receive the aforementioned first physical control channel on these at least a portion of the resources, or the terminal possessing the first terminal characteristic and the terminal possessing the second terminal characteristic can receive the aforementioned carried content. For example, as shown in Figure 6, the resource shown at 601 is the resource for the terminal possessing the first terminal characteristic to receive the first information or system information block, and the resource shown at 602 is the resource for the terminal possessing the second terminal characteristic to receive the first information or system information block. The resources shown at 601 and 602 have a common part, which is the shared resource or shared content.
[0124] In this way, since at least a portion of the resources or content carried by the first physical control channel are shared between the terminal with the first terminal characteristics and the terminal with the second terminal characteristics, resources and signaling overhead can be saved.
[0125] Similarly, the fact that at least a portion of the resources or content carried by the aforementioned main information block are shared by the terminal with the first terminal characteristic and the terminal with the second terminal characteristic can be understood as the fact that at least a portion of the resources or the content carried by the first physical control channel are sent to the terminal with the first terminal characteristic and the terminal with the second terminal characteristic, and can save resources and signaling overhead.
[0126] Similarly, the fact that at least a portion of the resources or content carried by the system information block are shared by the terminal with the first terminal feature and the terminal with the second terminal feature can be understood as the fact that at least a portion of the resources or the content carried by the first physical control channel are sent to the terminal with the first terminal feature and the terminal with the second terminal feature, and can save resources and signaling overhead.
[0127] Taking a terminal with the first terminal characteristic as an LPWA terminal and a terminal with the second terminal characteristic as a non-LPWA terminal (e.g., an eMBB terminal) as an example, as shown in Figure 6, the system information blocks of the LPWA terminal and the eMBB terminal share a portion. Since the eMBB terminal has unlimited transmission bandwidth, it can repeat the shared portion of the system information block in the frequency domain. As shown in Figure 6, the eMBB terminal can detect a system information block repeated four times in the frequency domain, one of which is shared with the LPWA terminal. For the LPWA terminal, due to its limited bandwidth, to ensure good coverage of the system information block, it repeats the transmission of the system information block in the time domain. As shown in Figure 3, the LPWA terminal repeats the system information block five times in the time domain. In summary, in one sharing method, using the shared system information block as the base, the eMBB terminal repeats the system information block in the frequency domain, and the LPWA terminal repeats the system information block in the time domain.
[0128] Another sharing method is that the eMBB terminal transmits the system information block shown in 602 as a whole, while the LPWA terminal essentially transposes the system information block of the eMBB terminal in the frequency domain to the time domain for transmission. Therefore, apart from the shared part, the other parts carry the same content or different content for both the eMBB terminal and the LPWA terminal.
[0129] Similarly, the fact that at least a portion of the resources or content carried by the physical shared channel carrying the main information block is shared between the terminal with the first terminal characteristic and the terminal with the second terminal characteristic can be understood as at least a portion of the resources or content being sent to the terminal with the first terminal characteristic and the terminal with the second terminal characteristic, thereby saving resources and signaling overhead.
[0130] As an optional implementation, the time-frequency domain resources corresponding to the first physical control channel used by the terminal with the first terminal characteristics and the terminal with the second terminal characteristics are different, or the content they carry is different; and / or
[0131] The terminals possessing the first terminal feature and the terminals possessing the second terminal feature respectively apply different time-frequency domain resources corresponding to the main information block or carry different content; and / or
[0132] The time-frequency domain resources corresponding to the system information blocks applied by the terminal with the first terminal feature and the terminal with the second terminal feature are different or carry different content; and / or
[0133] The time-frequency domain resources corresponding to the physical shared channels carrying the main information block used by the terminal with the first terminal feature and the terminal with the second terminal feature are different or carry different content.
[0134] It should be understood that the time-frequency domain resources corresponding to the first physical control channel used by the terminal with the first terminal characteristics and the terminal with the second terminal characteristics are different or the content they carry is different. This can be because the network-side device sends its own first physical control channel to the terminal with the first terminal characteristics and the terminal with the second terminal characteristics respectively. This can make the first physical control channel more targeted and improve the transmission performance of the first physical control channel.
[0135] The fact that the time-frequency domain resources corresponding to the main information blocks used by the terminals with the first terminal characteristics and the terminals with the second terminal characteristics are different or that the content they carry is different can be achieved by the network-side devices sending their respective main information blocks to the terminals with the first terminal characteristics and the terminals with the second terminal characteristics respectively. This can make the main information blocks more targeted and improve the transmission performance of the main information blocks.
[0136] The fact that the time-frequency domain resources corresponding to the system information blocks applied by the terminals with the first terminal characteristics and the terminals with the second terminal characteristics are different or that the content they carry is different can be achieved by the network-side device sending its respective system information blocks to the terminals with the first terminal characteristics and the terminals with the second terminal characteristics respectively. This makes the system information blocks more targeted, thereby improving the transmission performance of the system information blocks; and / or
[0137] The time-frequency domain resources corresponding to the physical shared channels carrying the main information block used by the terminal with the first terminal feature and the terminal with the second terminal feature are different or the content they carry is different. This can be achieved by the network-side device sending its own physical shared channel to the terminal with the first terminal feature and the terminal with the second terminal feature respectively. This can make the physical shared channel more targeted and improve the transmission performance of the physical shared channel.
[0138] In some implementations, the time-frequency domain resources corresponding to the first physical control channel used by the terminal with the first terminal feature and the terminal with the second terminal feature are the same or carry the same content. This allows the terminal with the first terminal feature and the terminal with the second terminal feature to share the same first physical control channel, thereby reducing system overhead.
[0139] In some implementations, the time-frequency domain resources corresponding to the main information block used by the terminal with the first terminal feature and the terminal with the second terminal feature are the same or carry the same content. This allows the terminal with the first terminal feature and the terminal with the second terminal feature to share the same main information block, thereby reducing system overhead.
[0140] In some implementations, the time-frequency domain resources corresponding to the system information blocks used by the terminal with the first terminal feature and the terminal with the second terminal feature are the same or carry the same content. This allows the terminal with the first terminal feature and the terminal with the second terminal feature to share the same system information blocks, thereby reducing system overhead.
[0141] In some implementations, the time-frequency domain resources corresponding to at least one of the physical shared channels carrying the main information block used by the terminal with the first terminal feature and the terminal with the second terminal feature are the same or carry the same content. This allows the terminal with the first terminal feature and the terminal with the second terminal feature to share the same physical shared channel, thereby reducing system overhead.
[0142] In some implementations, the first physical control channel is applied to a first type of terminal; or, the first physical control channel is applied to a second type of terminal and at least a portion of the first physical control channel is applied to the first type of terminal; and / or,
[0143] The main information block is applied to a first type of terminal, or the main information block is applied to a second type of terminal and at least a portion of the main information block is applied to a first type of terminal; and / or,
[0144] The system information block is applied to a first type of terminal, or the system information block is applied to a second type of terminal and at least a portion of the system information block is applied to a first type of terminal; and / or,
[0145] The physical shared channel carrying the main information block is applied to a first type of terminal, or the physical shared channel carrying the main information block is applied to a second type of terminal and at least a portion of the physical shared channel carrying the main information block is applied to a first type of terminal;
[0146] Wherein, the first terminal is a terminal of the first type, and the capabilities of the first type of terminal are lower than those of the second type of terminal, wherein the capabilities include at least one of the following:
[0147] Transmission bandwidth, radio frequency capability, baseband processing capability, transmit power capability, demodulation capability, and decoding capability.
[0148] Wherein, the application of at least a portion of the first physical control channel to a first type of terminal may include: at least a portion of the content carried by the first physical control channel being applied to the first type of terminal, or at least a portion of the time-frequency domain resources occupied by the first physical control channel being applied to the first type of terminal; and / or,
[0149] The application of at least a portion of the main information block to a first type of terminal may include: at least a portion of the content carried by the main information block being applied to the first type of terminal, or at least a portion of the time-frequency domain resources occupied by the main information block being applied to the first type of terminal; and / or,
[0150] The application of at least a portion of the system information block to a first type of terminal may include: at least a portion of the content carried by the system information block being applied to the first type of terminal, or at least a portion of the time-frequency domain resources occupied by the system information block being applied to the first type of terminal; and / or,
[0151] Applying at least a portion of the physical shared channel carrying the main information block to a first type of terminal may include: applying at least a portion of the time-frequency domain resources occupied by the physical shared channel carrying the main information block to the first type of terminal.
[0152] In this way, resource sharing and signaling overhead can also be saved.
[0153] Alternatively, in some implementations, the first physical control channel is applied to a first type of terminal; or, the first physical control channel is applied to a first type of terminal and at least a portion of the first physical control channel is applied to a second type of terminal; and / or,
[0154] The main information block is applied to a first type of terminal, or the main information block is applied to a first type of terminal and at least a portion of the main information block is applied to a second type of terminal; and / or,
[0155] The system information block is applied to a first type of terminal, or the system information block is applied to a first type of terminal and at least a portion of the system information block is applied to a second type of terminal; and / or,
[0156] The physical shared channel carrying the main information block is applied to a first type of terminal, or the physical shared channel carrying the main information block is applied to a first type of terminal and at least a portion of the physical shared channel carrying the main information block is applied to a second type of terminal;
[0157] The first terminal is the first type of terminal.
[0158] Wherein, the application of at least a portion of the first physical control channel to the second type of terminal may include: at least a portion of the content carried by the first physical control channel being applied to the second type of terminal, or at least a portion of the time-frequency domain resources occupied by the first physical control channel being applied to the second type of terminal; and / or,
[0159] The application of at least a portion of the main information block to the second type of terminal may include: at least a portion of the content carried by the main information block being applied to the second type of terminal, or at least a portion of the time-frequency domain resources occupied by the main information block being applied to the second type of terminal; and / or,
[0160] The application of at least a portion of the system information block to the second type of terminal may include: at least a portion of the content carried by the system information block being applied to the second type of terminal, or at least a portion of the time-frequency domain resources occupied by the system information block being applied to the second type of terminal; and / or,
[0161] Applying at least a portion of the physical shared channel carrying the main information block to a second type of terminal may include: applying at least a portion of the time-frequency domain resources occupied by the physical shared channel carrying the main information block to a second type of terminal;
[0162] In this way, resource sharing and signaling overhead can also be saved.
[0163] As an optional implementation, the frequency domain resources of at least one of the first information and the system information block satisfy at least one of the following:
[0164] It occupies the same frequency domain resources as the primary synchronization signal (PSS) or secondary synchronization signal (SSS), is a frequency domain resource within a specific bandwidth, and has the same center frequency as the PSS or SSS.
[0165] The aforementioned use of the same frequency domain resources as PSS or SSS can be illustrated in Figures 7 and 8. Figures 7 and 8 include the frequency domain resources of PSS and SSS, with the frequency domain resources occupying the same range as PSS or SSS being the f0–f215 portion shown. It can be understood that the f0–f215 portion of the frequency domain resources shown represents frequency domain resources within a specific bandwidth. That is, in Figure 7, for a terminal possessing the first terminal characteristic, it cannot receive the frequency domain resources in the f216–f431 portion.
[0166] By occupying the same frequency domain resources as PSS or SSS, the first terminal can receive at least one of the first information and system information blocks, as well as at least one of PSS and SSS, thereby improving the reception performance of the first terminal.
[0167] The aforementioned specific bandwidth can be a bandwidth agreed upon in the protocol or a bandwidth configured by the network-side device. For example, the aforementioned specific bandwidth satisfies at least one of the following: the specific bandwidth includes the frequency domain resources where the PSS or SSS is located; the specific bandwidth is greater than or equal to the frequency domain resources occupied by the PSS or SSS; or the specific bandwidth satisfies the bandwidth capability of a terminal possessing the first terminal characteristic. In one embodiment, the bandwidth capability of a terminal possessing the first terminal characteristic is a bandwidth of 3MHz.
[0168] For example, a specific bandwidth can be equal to the size of the PRB resource where the PSS or SSS resides, such as 12 PRBs. Alternatively, the specific bandwidth can also be any other bandwidth size that meets the transmission bandwidth requirements of LPWA, such as 14 PRBs.
[0169] By using the frequency domain resources within the aforementioned specific bandwidth, the first terminal can receive at least one of the first information and system information blocks within the aforementioned specific bandwidth, thereby improving the receiving performance of the first terminal.
[0170] The above-mentioned center frequency point being the same as that of PSS or SSS means that the center frequency point of the frequency domain resource of at least one of the first information and system information blocks is the same as that of PSS or SSS. This enables the first terminal to receive at least one of the first information and system information blocks, as well as at least one of PSS and SSS, thereby improving the reception performance of the first terminal.
[0171] As an optional implementation, the repeated transmission of the first physical control channel during the first time period satisfies at least one of the following:
[0172] The information content carried is the same, the transmission parameters are the same, the first time period is less than or equal to the first duration, the interval between two adjacent transmissions is greater than or equal to the first interval threshold, the interval between two adjacent transmissions is less than the second interval threshold, repeated transmissions are carried within one time resource or repeated transmissions are carried between multiple time resources, all repeated transmissions are associated with the same control resource set (CORESET), and all repeated transmissions are associated with the same search space.
[0173] The above-mentioned identical information content and identical transmission parameters mean that the information content and transmission parameters carried by the first physical control channel in each transmission during the first time period are identical.
[0174] The same transmission parameters mentioned above may include at least one of the following:
[0175] The aggregation levels are the same, the candidate positions of the associated physical control channels are the same, the starting positions or CCE indices of the associated control channel elements (CCEs) are the same, the associated reference signals are the same, the mapping methods from control channel elements to resource element groups are the same, and the transmission control indication states are the same.
[0176] The above-mentioned identical physical control channel candidate positions can mean that the control information carried by the first physical control channel is associated with the same physical control channel candidate position, that is, it is transmitted on the same PDCCH candidate; the above-mentioned identical CCE start position or CCE index can mean that the control information carried by the first physical control channel is associated with the same CCE start position or CCE index; the above-mentioned identical reference signal means that the reference signal associated with the first physical control channel is the same.
[0177] The mapping method from the control channel element to the resource element group is the same, which can be interleaved or non-interleaved. The mapping method from the CCE to the resource element group (REG) is the same.
[0178] In the above embodiments, since the information content and transmission parameters are the same, the transmission complexity of the first physical control channel can be reduced. For example, taking the first information as PDCCH and the system information block as SIB1 as an example, as shown in Figure 9, the first information transmitted in the first and fourth transmissions is associated with the same time slot and CCE index, which can reduce the transmission complexity of the first information.
[0179] The aforementioned first duration, first interval threshold, and second interval threshold can be agreed upon in the protocol or the duration of the network-side device. The specific values can be set according to actual business needs.
[0180] Since the first time period is less than or equal to the first duration, this avoids sending too many first physical control channels, thus saving transmission overhead.
[0181] The interval between two adjacent transmissions is greater than or equal to the first interval threshold, so that there is a certain interval between the two transmissions, thereby improving the transmission reliability of the first physical control channel.
[0182] The fact that the interval between two adjacent transmissions is less than the second interval threshold can prevent the interval between the two transmissions from being too small, which could lead to incorrect reception by the terminal, thereby improving the reliability of the first physical control channel transmission.
[0183] The aforementioned time resources can be time slots or sub-time slots. The repeated transmission within a time resource or between multiple time resources allows the first physical control channel to transmit flexibly.
[0184] The fact that all the aforementioned repeated transmissions are associated with the same information can reduce the complexity of repeated transmissions, and the search space for all the aforementioned repeated transmissions being associated with the same information can also reduce the complexity of repeated transmissions.
[0185] As an optional implementation, the first physical control channel is used to indicate first scheduling information of the system information block, the first scheduling information including at least one of the following:
[0186] Coverage level or coverage identifier, time domain resource allocation information, frequency domain resource allocation information, first time interval, modulation and coding scheme (MCS), redundancy version (RV), number of repeated transmissions, repeated transmission identifier, associated reference signal, transmission beam, spatial filtering parameters, transmission control indication status, transmission parameter set, and transport block size (TBS).
[0187] Wherein, the first time interval is the start time of the first transmission of the system information block in the second time period or the interval between the start time of the second time period and the first end time, and the first end time includes: the end time of the last repeated transmission of the first information in the first time period, or the end time of the first time period.
[0188] In some implementations, the aforementioned time-domain resource allocation information is used to indicate the absolute time position of the system information block, or the time-domain resource allocation information is used to indicate the index information of the starting time unit of the system information block. For example, the absolute time position of the scheduled system information block may indicate the starting system frame number (SFN) index or the starting timeslot index of the system information block's time-domain resources. This avoids problems such as inconsistent time-domain starting positions of scheduled system information blocks indicated by multiple first physical control channels, preventing merging, or inconsistent understanding of the time-domain starting positions of scheduled system information blocks due to relative positions, leading to demodulation errors in the system information blocks.
[0189] The aforementioned set of transmission parameters can be an index indicating the set of transmission parameters. For example, the protocol defines multiple sets of transmission parameters, and the physical control channel indicates one set of parameter values for system information block transmission, thereby saving transmission overhead.
[0190] In the above embodiments, the system information blocks can be flexibly scheduled by instructing the scheduling information, so that the system information blocks can be flexibly transmitted to meet the needs of different services or different terminals and improve system compatibility.
[0191] As an optional implementation, the above-mentioned main information block is used to indicate at least one of the following:
[0192] The system information block's second scheduling information, the system information block's scheduling method, the system information block's associated rate matching pattern, the length of the second time period, the length of the first time period, and the transmission resource configuration of the first physical control channel;
[0193] The second scheduling information includes at least one of the following:
[0194] First time interval, coverage level, associated reference signal, transmission beam, spatial filtering parameters, transmission control indication status, transmission parameter set of the system information block, TBS of the system information block, number of repeated transmissions;
[0195] The first time interval is the start time of the first transmission of the system information block in the second time interval or the interval between the start time of the second time interval and the first end time. The first end time includes: the end time of the last repeated transmission of the first information in the first time interval, or the end time of the first time interval.
[0196] The scheduling method of the system information block includes at least one of scheduling the system information block through the main information block or scheduling the system information block through the first physical control channel;
[0197] The first information is repeatedly transmitted within a first time period, and the system information block is repeatedly transmitted within a second time period.
[0198] The aforementioned second scheduling information allows for flexible scheduling of the system information blocks, enabling flexible transmission of these blocks to meet the needs of different services or terminals and improve system compatibility.
[0199] The rate matching mode associated with the aforementioned system information block can explicitly or implicitly indicate the transmission resources of the aforementioned system information block. For example, the rate matching mode associated with the system information block is used for at least one of the following:
[0200] Indicates resources used for the system information block transport mapping and resources not used for the system information block transport mapping.
[0201] For example, the master information block may indicate that a specific resource element (RE) or symbol within a resource block (RB) cannot be used for the transmission of the system information block, or conversely, it may indicate that a particular RE or symbol within an RB can be used for the transmission of the system information block. Another example is that the master information block may indicate which RBs in the frequency domain within the transmission bandwidth can or cannot be used for the transmission of the system information block. Yet another example is that four rate matching patterns are predefined, and 2 bits in the first master information block indicate the application of one of these rate matching patterns. In one embodiment, this rate matching pattern may be periodic.
[0202] For example, rate matching can be performed on 5G NR Synchronization Signal Blocks (SSBs), Tracking Reference Signals (TRSs), and Low Power Synchronization Signals (LP-SSs) in related technologies through rate matching mode configuration, so that the resources of these signals can be used for the transmission of system information blocks. The SSB includes at least one of the following: periodic SSB or on-demand SSB activated in network energy saving (NES).
[0203] The length of the second time period can be extended or the transmission cycle of the system information block can be flexibly set, making the transmission of the system information block more reliable.
[0204] In some implementations, the main information block indicating the length of the second time period includes:
[0205] The main information block indicates the length of the second time period and the transmission period of other system information blocks; or
[0206] The main information block indicates the relationship between the length of the second time period and the transmission period of other system information blocks.
[0207] The aforementioned other system information blocks can be other system information blocks besides those mentioned above, such as those specified by the protocol or network-side devices, such as SIB2, SIB3, etc.
[0208] For example, the transmission period of system information blocks can be extended by indicating the main information block, thereby allowing the merging of more system information blocks. This could involve indicating that the second time period length is extended by a factor of X or reduced by a factor of Y, where X and Y are positive integers. Alternatively, the protocol or network side can configure a default second time period length, based on which the length is extended.
[0209] The above-mentioned indication method allows for more flexible indication of the length of the second time period, and the relationship between the length of the second time period and the transmission cycle of other system information blocks indicated by the main information block can save signaling overhead.
[0210] The length of the first time period can be extended or the transmission period of the first information can be flexibly set, making the transmission of the first information block more reliable.
[0211] The aforementioned main information block indicates the transmission resource configuration of the first physical control channel. This can be either activating or deactivating the main information block to indicate the transmission resource configuration of the first physical control channel, or indicating the specific configuration of the transmission resources of the first physical control channel.
[0212] In some implementations, the master information block indicates that the transmission resource configuration of the first physical control channel includes at least one of the following:
[0213] Activate or deactivate the transmission resource configuration of the first physical control channel;
[0214] The length of the third time period of the first physical control channel, wherein the first physical control channel is repeatedly transmitted within the third time period;
[0215] The time-domain resource allocation information of the first physical control channel;
[0216] Frequency domain resource allocation information of the first physical control channel;
[0217] The aggregation level of the first physical control channel;
[0218] The physical control channel candidate position associated with the control information carried by the first physical control channel;
[0219] The starting position or CCE index associated with the control information carried by the first physical control channel;
[0220] The reference signal associated with the first physical control channel;
[0221] The mapping method from the control channel element associated with the first physical control channel to the resource element group;
[0222] The transmission control indication status of the first physical control channel;
[0223] Specifically, when the main information block activates the transmission resource configuration of the first physical control channel, the system information block is scheduled through the first physical control channel.
[0224] Wherein, if the first information is the first physical control channel, the third time period may be the first time period, or the third time period may include the first time period.
[0225] Through the above implementation method, the transmission resources of the first physical control channel can be flexibly configured through the main information block to improve the transmission reliability of the first physical control channel.
[0226] In some implementations, the system information block is scheduled via the first physical control channel when the main information block indicates at least one of the transmission resource configuration of the first physical control channel and the length of the first time period corresponding to the first physical control channel. This implicitly indicates the scheduling method of the system information block, thereby saving signaling overhead.
[0227] As an optional implementation, the first terminal receiving the system information block based on the first information includes at least one of the following:
[0228] When the first information includes the main information block and the main information block indicates the scheduling method of the system information block, the first terminal receives the main information block and determines the scheduling method of the system information block based on the main information block; the first terminal obtains the scheduling information of the system information block based on the scheduling method; the first terminal receives the system information block based on the scheduling information of the system information block.
[0229] When the first information includes the main information block and the first physical control channel, and the main information block indicates the transmission resource configuration of the first physical control channel, the first terminal receives the main information block and determines the transmission resource configuration of the first physical control channel based on the main information block; the first terminal receives the first physical control channel based on the transmission resource configuration of the first physical control channel, and obtains the scheduling information of the main information block based on the first physical control channel; the first terminal receives the system information block based on the scheduling information of the main information block.
[0230] As an optional implementation, the mapping pattern of the main information block or the physical broadcast channel carrying the main information block includes: a first mapping pattern or a second mapping pattern;
[0231] The first mapping pattern includes a first time-frequency resource and a second time-frequency resource. The first time-frequency resource carries the content of the physical broadcast channel outside a specific bandwidth, and the second time-frequency resource carries the content of the physical broadcast channel within the specific bandwidth. The time-frequency resource of the second mapping pattern carries the content of the physical broadcast channel within the specific bandwidth.
[0232] The specific bandwidth mentioned above refers to the corresponding description in the above implementation method, and will not be repeated here. For example, the specific bandwidth satisfies at least one of the following: the specific bandwidth includes the frequency domain resources where the PSS or SSS is located, the specific bandwidth is greater than or equal to the frequency domain resources occupied by the PSS or SSS, and the specific bandwidth satisfies the bandwidth capability of the terminal with the first terminal feature.
[0233] The aforementioned first mapping pattern, including both first and second time-frequency resources, can be understood as the resources mapped by the first mapping pattern including both first and second time-frequency resources. Taking the specific bandwidth containing the frequency domain resources of the PSS or SSS as an example, the aforementioned second time-frequency resource can be the time-frequency resource of the f0 to f215 portion as shown in Figure 7 or Figure 8. It should be noted that the time-frequency resources of the f0 to f215 portion in the SSB in the figure are separated by one symbol, and the subsequent f0 to f215 portion occupies adjacent time-frequency domain resources in the physical broadcast channel transmission. For example, the second time-frequency domain resource can be understood as the time-frequency domain resource with the same bandwidth as the PSS or SSS. The first time-frequency resource is the time-frequency resource of the f216 to f431 portion occupied by the physical broadcast channel in the SSB as shown in Figure 7 or Figure 8. The time-frequency resources of the physical broadcast channel in the SSB, specifically the portion from f216 to f431, were originally outside the frequency domain bandwidth of the PSS and SSS. Therefore, the first time-frequency resource carries the content of the physical broadcast channel outside the specific bandwidth, which is the time-frequency resource of the physical broadcast channel in the SSB, specifically the portion from f216 to f431. The time-frequency resources of the second mapping pattern mentioned above refer to the time-frequency resources of the physical broadcast channel corresponding to the bandwidth of the aligned PSS or SSS in the SSB, i.e., the time-frequency resources of the portion from f0 to f215.
[0234] Optionally, the first mapping pattern may include one or more transmissions of the physical broadcast channel. For example, the first mapping pattern shown in Figure 7 includes two transmissions of the physical broadcast channel. For example, in Figure 8, a second mapping pattern includes four transmissions of the physical broadcast channel.
[0235] The first mapping pattern or the second mapping pattern described above can enable the first terminal to receive more signals, thereby improving the communication performance of the first terminal.
[0236] It should be noted that, except for PSS and SSS, the entire pattern shown in Figure 7 is considered the first mapping pattern. Except for PSS and SSS, the entire pattern shown in Figure 8 is considered the second mapping pattern.
[0237] In one embodiment, the repeated transmission of the main information block within a first time period means that the main information is repeatedly transmitted within a first time period based on the first mapping pattern or the second mapping pattern.
[0238] In one embodiment, the above-described design for system information blocks or first information (which may be part or all of them, such as the design of mapping patterns or the design of repeated transmission, etc.) can be applied to or extended to the transmission of at least one of the following information: paging, PDCCH or PDSCH of message 2 (msg2, referring to RAR) during random access, and PDCCH or PDSCH of message 4 (msg4) during random access. These details will not be elaborated here.
[0239] It should be noted that the various implementation methods provided in this application can be combined with each other or implemented individually, and there is no limitation thereto.
[0240] In this embodiment, a first terminal receives first information; the first terminal receives a system information block based on the first information, the system information block being used to provide information related to cell camping or initial access; wherein, the first information includes at least one of the following: a first physical control channel and a master information block. Since the first information includes at least one of the first physical control channel and the master information block, the system information block can be received based on at least one of the first physical control channel and the master information block, thereby determining the method by which the terminal receives the system information block and improving the reliability of the terminal receiving the system information block. Furthermore, since the system information block is used to provide information related to cell camping or initial access, this makes it easier for the terminal to obtain the relevant information, enabling the terminal to perform cell camping or initial access more effectively and improving the terminal's communication performance.
[0241] Please refer to Figure 10, which is a flowchart of an information sending method provided in an embodiment of this application. As shown in Figure 10, it includes the following steps:

[0301] It should be noted that this embodiment is an implementation of the network-side device corresponding to the embodiment shown in Figure 2. For the specific implementation, please refer to the relevant description of the embodiment shown in Figure 2. In order to avoid repeated description, this embodiment will not be repeated.
[0302] The methods provided in the embodiments of this application are illustrated below through multiple examples:
[0303] Example 1:
[0304] In this embodiment, the first terminal receives first information, which includes scheduling-related information for system information blocks (such as SIB1), and the system information blocks are used to provide terminal cell camping or initial access-related information.
[0305] The terminal receives system information blocks based on the first information.
[0306] Wherein, the first information is repeated within a first time period (the first time period can be understood as the transmission cycle of the first information); the system information block is repeated within a second time period (the second time period can be understood as the transmission cycle of the system information block); the first information can be carried by at least one of the following:
[0307] The downlink control information carried by the aforementioned first physical control channel is scrambled by a specific radio network temporary identifier (RNTI), or the aforementioned first physical control channel is located at a specific time-frequency domain position.
[0308] The main information block (e.g., MIB) is used to provide timing information, including at least one of the cell access information.
[0309] In some implementations, the first time period is less than or equal to the second time period, or the first time period and the second time period are multiples of each other.
[0310] In some implementations, the starting positions of the first time period and / or the second time period are agreed upon by a protocol. For example, the starting position of the first time period is obtained by the formula (SFN index + offset) mod first time period length = 0.
[0311] In some implementations, the master information block is carried by a physical broadcast channel (e.g., a physical broadcast channel (PBCH)), and the mapping pattern of the physical broadcast channel on time-frequency domain resources includes at least one of the following:
[0312] The mapping pattern shown in Figure 7 above: the information carried by the PBCH in an SSB is mapped into blocks of f0 to f215 and f216 to f431. For eMBB terminals, since there is no bandwidth limitation, these terminals can receive only the first SSB. However, for LPWA terminals, due to bandwidth limitation, the f216 to f431 portion cannot be included in their receiving bandwidth. The receiving bandwidth of LPWA terminals only includes the PSS, SSS, and the f0 to f215 portion (that is, the SSB transmission content of 12 PRBs). One interpretation is that for LPWA terminals, the f216 to f431 portion can be understood as being rate-matched or punctured. To improve the coverage of the physical broadcast channel of the LPWA terminal, it is necessary to extend the transmission of the physical broadcast channel in the time domain. One embodiment includes: for the LPWA terminal, the information mapping pattern in the transmission of the additional master information block or the PBCH carrying the master information block is as follows: first map f216 to f431, so that the f216 to f431 part that the LPWA cannot receive in the first normal SSB can be first mapped to the additional time domain PBCH transmission resources to form the first complete PBCH transmission for the LPWA terminal; then map the second master information block or the PBCH carrying the master information block.
[0313] The mapping pattern 2 shown in Figure 8 above: the information carried by the PBCH in an SSB is mapped into blocks of f0 to f215 and f216 to f431. For eMBB terminals, since there is no bandwidth limitation, these terminals can receive only the first SSB. However, for LPWA terminals, due to bandwidth limitation, the f216 to f431 portions cannot be included in their receiving bandwidth. The receiving bandwidth of the LPWA terminal only includes the PSS, SSS, and f0 to f215 portions (that is, the SSB transmission content of 12 PRBs). In order to improve the coverage of the physical broadcast channel of the LPWA terminal, it is necessary to extend the transmission of the physical broadcast channel in the time domain. One embodiment includes: for the LPWA terminal, the information mapping pattern in the additional PBCH transmission is: only the f0 to f215 portions are mapped. As shown in Figure 8, the LPWA terminal can receive 4 repeated PBCH transmissions, and each received main information block or PBCH transmission carrying the main information block only includes the f0 to f215 portions.
[0314] In some implementations, at least one of the following is included:
[0315] The main information block is applied to low-power wide-coverage LPWA terminals, or is applicable to low-power wide-coverage terminals and non-low-power wide-coverage non-LPWA terminals;
[0316] The first physical control channel is applicable to low-power wide-coverage terminals, or to both low-power wide-coverage terminals and non-low-power wide-coverage terminals;
[0317] The system information block is applied to low-power wide-coverage (LPWA) terminals, or is applicable to both low-power wide-coverage terminals and non-low-power wide-coverage (non-LPWA) terminals.
[0318] In some implementations, the low-power wide-coverage terminal is a terminal with limited transmission bandwidth, such as a terminal whose transmission bandwidth does not exceed a specific threshold (e.g., not exceeding 3MHz).
[0319] In some implementations, a PDSCH (SIB1 PDSCH) and / or the first physical control channel (PDCCH for scheduling SIB1, or SIB1 PDCCH) carried by system information blocks is designed to be partially shared by LPWA and non-LPWA terminals (eMBB terminals are exemplified in the figure). The system information blocks and / or the first physical control channel can be partially shared by the two types of terminals. One sharing method is shown in Figure 6 above:
[0320] In one embodiment, the shared SIB1 PDSCH is used as an example for illustration (the same sharing method can be used for the shared SIB1 PDCCH, which will not be described again). As shown in Figure 6 above, the SIB1 of the LPWAUE and the SIB1 of the eMBB UE share a portion. Furthermore, it should be noted that in this embodiment, the content transmitted for the SIB1 of both the eMBB and LPWAUE is the same.
[0321] One sharing method involves the eMBB UE, due to its unrestricted transmission bandwidth, repeating the portion of SIB1 shared with the LPWA UE in the frequency domain. As shown in the figure, the eMBB UE can detect SIB1 repeated four times in the frequency domain, with one SIB1 shared with the LPWA UE. However, for the LPWA UE, due to its limited bandwidth, to ensure good SIB1 coverage, it repeats SIB1 transmission in the time domain. As shown in the figure, the LPWA UE's SIB1 is repeated five times in the time domain. In summary, in this sharing method, using the shared SIB1 as the base, the eMBB UE repeats SIB1 in the frequency domain, while the LPWA UE repeats SIB1 in the time domain.
[0322] Another sharing method is that the eMBB UE transmits SIB1 as a whole in the box shown in 602, while the LPWA UE essentially transposes the eMBB UE's SIB1 in the frequency domain to the time domain for transmission. Therefore, apart from the shared part, the other parts carry the same SIB1 content for both the eMBB and LPWA UEs.
[0323] Furthermore, the above embodiments are not limited to the fact that the LPWAUE and eMBB UE have the same number of SIB1 transmission repetitions in both the time and frequency domains.
[0324] In some implementations, for each repeated transmission of the first information and system information block, the first scheduling information and the SIB1 receiving position are within the same first time unit, or are separated by a first time interval.
[0325] In some implementations, the reception of the first repeated transmission of the system information block begins at the end time of the last repeated transmission of the first information or the end time of the first time period, with a second time interval between the start time and the start time of the second time period.
[0326] In some implementations, the repeated transmission of the first physical control channel satisfies at least one of the following:
[0327] Carrying the same information content;
[0328] Use the same aggregation level;
[0329] Transmissions are performed on the same PDCCH candidate;
[0330] The PDCCH candidate where the transmission is located satisfies the condition that the CCE start position is the same or the CCE index is the same;
[0331] Associated with the same CORESET;
[0332] Related to the same search space;
[0333] The first time period satisfies a value less than or equal to a specific value;
[0334] The interval between two adjacent repeated transmissions must be greater than, less than, or equal to a specific time interval;
[0335] Associated with the same first reference signal (e.g., SSB);
[0336] They have the same transmission control indication status;
[0337] Repeated transmission within a time slot (Intra-slot), between time slots (inter-slot), or within a control resource set;
[0338] The mapping method from control channel elements to resource element groups in the resources used (e.g., the mapping method from interleaved or non-interleaved CCE to REG) is the same;
[0339] The restriction on repeated transmission of the first physical control channel within the first time period means that, within a certain time range, the first PDCCH is subject to the above restriction, but there is no restriction between different transmission periods.
[0340] In some implementations, the first physical control channel indicates that the transmission channel in which the system information block resides is related to at least one of the following:
[0341] Time-domain and / or frequency-domain resource allocation information; wherein, the time-domain resource indicates the absolute time position of the scheduled system information block, for example, indicating the starting SFN index or starting slot index of the system information block's time-domain resource. This method can avoid problems such as inconsistent time-domain starting positions of scheduled system information blocks indicated by multiple first physical control channels, leading to merging failures, or inconsistent interpretations of the time-domain starting positions of scheduled system information blocks due to relative positions, resulting in demodulation errors of the system information blocks.
[0342] The second time interval begins at the end of the last repeated transmission of the first information or at the end of the first time period.
[0343] MCS;
[0344] RV;
[0345] The number of repeated transmissions or its identifier;
[0346] Coverage ratings or their designations;
[0347] Associated reference signal;
[0348] Transmit beam or spatial filtering parameters or transmit control indication status;
[0349] The index of the transmission parameter set. For example, the protocol defines multiple sets of transmission parameter sets, and the physical control channel indicates one set of parameter values for the transmission of system information blocks.
[0350] In some implementations, the first master information block indicates at least one of the following:
[0351] The second time interval;
[0352] The system information block scheduling method includes: 1) carrying system information block scheduling indication information through the first main information block, and 2) carrying system information block scheduling indication information through the first PDCCH.
[0353] The system information block contains a rate matching pattern indication. For example, the first main information block may indicate that a specific RE or symbol in an RB cannot be used for the transmission of the system information block, or conversely, it may indicate that a particular RE or symbol in an RB can be used for the transmission of the system information block. Another example is that the first main information block may indicate which RBs in the frequency domain within the transmission bandwidth can or cannot be used for the transmission of the system information block. Yet another example is that four rate matching patterns are predefined, and 2 bits in the first main information block indicate the application of one of these patterns. This pattern is similar to the current RM pattern and can be periodic. It should be noted that the indication content of the first main information block is consistent within a transmission cycle of the first main information block. For example, the rate matching pattern can be configured to perform rate matching for related technologies such as 5G NR SSB (including at least one of periodic SSB or ON demand SSB activated in NES), TRS, and LP-SS.
[0354] The length indication of the second time period (transmission cycle of the system information block) is as follows: the transmission cycle of the system information block is usually fixed and cannot be extended. In this embodiment, the transmission cycle of the system information block can be extended through the MIB indication, thereby merging more SIB1s. For example, the indication can be to extend the length of the second time period by X times or reduce it by Y times. Here, X and Y are positive integers. In addition, the protocol or network side configures a default length of the second time period, and the length extension is based on this. Furthermore, the above-mentioned transmission cycle length indication of the system information block can include: the transmission length indication of system information block 1 and other system information blocks, or the transmission length of system information block 1 is associated with the transmission length of other system information blocks. For example, if the transmission length indication of the system information block is extended by 1 time, then the transmission length of other system information blocks is also extended by 1 time.
[0355] In the case of information from the first PDCCH scheduling system, the length of the first time period (transmission cycle) of the PDCCH is indicated;
[0356] In the case of system information scheduled by the first PDCCH, activate or deactivate additional first PDCCH transmission resource configurations; further, determine whether to activate or deactivate additional first PDCCH transmission resource configurations based on the transmission period of the configured system information block.
[0357] Coverage rating or its identifier;
[0358] Associated reference signal;
[0359] Transmission beam or spatial filtering parameters or transmission control indication status;
[0360] An index of a set of transmission parameters. For example, a protocol defines multiple sets of transmission parameter sets, and the physical control channel indicates one set of parameter values for system information block transmission.
[0361] TBS of system information blocks;
[0362] The number of times a system information block is repeated or its identifier.
[0363] The scheduling-related information of the remaining first system information block is predefined by the protocol.
[0364] In some implementations, the first terminal receiving first information and receiving system information blocks based on the first information includes the following steps:
[0365] The first terminal receives the first master information block and determines the scheduling method of the system information block according to the scheduling method of the system information block indicated by the first master information block;
[0366] The first terminal receives the system information block according to the scheduling method of the system information block indicated by the first main information block, by receiving scheduling information of other system information blocks of the first main information block or by further receiving scheduling information of the system information block from the first PDCCH.
[0367] In some implementations, when the first information is carried by a first main information block, during the second time period of the system information block, the transmission pattern between the main information block and the system information block satisfies at least one of the following:
[0368] The first time period for repeated transmission of the main information block is greater than or not less than the second time period for repeated transmission of the system information block;
[0369] Each repeated transmission of the main information block is associated with the repeated transmission of the same or different number of system information blocks;
[0370] Each repeated transmission of the main information block is associated with one or more repeated transmissions of the corresponding system information block.
[0371] It should be noted that in this embodiment, the above-mentioned SIB1 can also be broadly referred to as a system information block, and the MIB can also be broadly referred to as a main information block.
[0372] Example 2:
[0373] This embodiment describes the scheduling of system information blocks, such as SIB1, via the first PDCCH.
[0374] In this embodiment, as shown in Figure 4 above, for each repetition, the first PDCCH and the PDSCH carrying SIB1 are transmitted within the same time unit / transmission opportunity. For example, they are transmitted in the same slot and the same subframe. Furthermore, each first PDCCH schedules a corresponding PDSCH carrying SIB1, and the first PDCCH and SIB1 complete all transmissions within the same time period. This same time period can be determined based on the transmission cycle of SIB1 agreed upon by the network-side device or protocol. Within one transmission cycle of SIB1, the terminal can consider SIB1 to be retransmitted repeatedly, with the content carried by SIB1 being the same or unchanged. In the following example, the number of repetitions of the first PDCCH and SIB1 is the same, or in other words, the number of repetitions of SIB1 depends on the number of repetitions of the first PDCCH.
[0375] The advantage of this repetition is that the scheduling method of SIB1 via PDCCH in related technologies can be applied. For terminals with low power consumption requirements and wide deployment (LPWA) or limited coverage, coverage can be provided through multiple repeated receptions. For normal-capability terminals such as eMBB without coverage limitations, the scheduled SIB1 can be obtained by receiving the first PDCCH once. In some embodiments, the first PDCCH carries the time-frequency domain resource information of SIB1 and other necessary indication information for obtaining SIB1.
[0376] In some implementations, the first time period or the second time period in Figure 4 above corresponds to the PDCCH transmission cycle or the SIB 1 transmission cycle, respectively, and the PDCCH or SIB 1 is repeatedly transmitted within a transmission cycle.
[0377] Example 3:
[0378] In this embodiment, after the first information (such as PDCCH) transmission is completed, the first repeated transmission of the system information block (such as SIB1) is scheduled, and the repeated transmission of the remaining SIB1 is determined based on the transmission of the first SIB1.
[0379] In this embodiment, as shown in Figure 5 above, the first PDCCH is repeated first, and then the PDSCH of the scheduled bearer SIB1 is received. Optionally, the repetition of the first PDCCH is implemented within a first time period or within a time unit.
[0380] As shown in Figure 5 above, four PDCCH repetitions can be designed and implemented within a single slot. For example, the four PDCCH repetitions occur during the four PDCCH listening events within a single slot.
[0381] In some implementations, the listening timing of the four PDCCHs is associated with a search space set, or the listening timing of the four PDCCHs is achieved by associating each of their own search space sets.
[0382] In addition, to avoid confusion in the relative offset of the scheduled PDSCH due to the failure to receive a certain repetition, the offset of the scheduled PDSCH in the PDCCH can be configured / indicated relative to the end position of the time unit where all repetitions of the PDCCH occur or relative to the end position of the first time period, as shown in Figure 5 above.
[0383] In some implementations, one embodiment involves the four repeated PDCCHs scheduling the same PDSCH, as shown in the figure, scheduling only the transmission of the first SIB1. Subsequent repeated transmissions of SIB1 are determined relative to the transmission of the first SIB1. For example, the resources occupied by subsequent SIB1s and the transmission-related parameters are consistent with the first SIB1 transmission, except for the time-domain location. Alternatively, the transmission-related parameters between the first SIB1 and subsequent repeated SIB1 transmissions are indicated by the PDCCH scheduling SIB1s (e.g., the first PDCCH carries the relative positional relationship between subsequent SIB1 transmissions and the first SIB1 transmission), or are agreed upon by the protocol.
[0384] In some implementations, the transmission of the four repeated SIB1s in Figure 5 above is completed within a second time period, which may be agreed upon by the protocol or dynamically indicated by the first PDCCH.
[0385] In other implementations, the design of scheduling all repeated PDSCH / SIB1 transmissions in the first PDCCH is not excluded. For example, the repeated SIB1 transmissions are treated as a whole and scheduled in the PDCCH scheduling. Another example is that each repeated PDCCH transmission is scheduled to correspond to a repeated transmission of one SIB1.
[0386] Compared to Embodiment 2, the design of this embodiment may require a redesign of the PDCCH retransmission. For example, the PDCCH retransmission occurs on multiple PDCCH MOs within a slot.
[0387] In some implementations, the first time period or the second time period in Figure 5 above corresponds to the PDCCH transmission cycle or the SIB 1 transmission cycle, respectively, and the PDCCH or SIB 1 is repeatedly transmitted within a transmission cycle.
[0388] Example 4:
[0389] In order to further reduce the complexity of blind detection of the first information (such as the first PDCCH) of the LPWA terminal, the following restrictions are imposed on the repeated transmission of the first PDCCH in this embodiment.
[0390] To reduce the complexity of PDCCH detection in LPWA terminals, Embodiment 4 can further limit the repeated transmission of the first PDCCH or the repeated transmission of system information blocks (such as SIB1) based on Embodiment 2 or Embodiment 3.
[0391] For example, as shown in Figure 9 above, taking the implementation of Embodiment 3 as an example (it can be understood that Embodiment 4 is also applicable to Embodiment 2, and will not be repeated here), the blind detection parameters of the first PDCCH are limited. In one embodiment, all repeated transmissions of the first PDCCH are limited to the same candidate PDCCH at their respective PDCCH detection times. This can be understood as the PDCCH candidate corresponding to all repeated transmissions of PDCCH in Figure 9 above having the same CCE index. Or, the PDCCH candidate where the repeated transmissions of PDCCH are located has the same CCE starting position and / or the same aggregation level. Furthermore, all repeated transmissions of PDCCH are limited to carrying the same content.
[0392] Of course, in other implementations, it is not necessary to limit the PDCCH candidate positions of repeated transmissions of the first PDCCH to be the same.
[0393] Furthermore, if the repeated transmission of the first PDCCH occurs in different slots, the timing of PDCCH monitoring is further limited to the same symbol in different slots.
[0394] In other implementations of Figure 9 above, repeated transmissions of the first PDCCH can be associated with different search spaces (SS) or with different PDCCH transmission times of the same SS.
[0395] It should be noted that the search space and the set of search spaces are the same concept.
[0396] In some implementations, the first time period or the second time period in Figure 9 above corresponds to the PDCCH transmission cycle or the SIB1 transmission cycle, respectively, and the PDCCH or SIB1 is repeatedly transmitted within a transmission cycle.
[0397] Example 5:
[0398] In this embodiment, first information (such as MIB) is used to schedule system information blocks (such as SIB1), and the pattern design between MIB or SSB and SIB1 is used.
[0399] In some implementations, since the information that the MIB can carry is limited, some information required for SIB1 scheduling (e.g., SIB1's time-domain resources and / or frequency-domain resources) can be pre-defined through protocol configuration. The MIB is only used to carry / indicate the remaining scheduling information of SIB1 (e.g., repetition count and / or TBS).
[0400] In some implementations, the pattern between the MIB or SSB and SIB1 can have the following options: Option 1: In one transmission cycle, the relationship between multiple repeated transmissions of the MIB (such as the fourth transmission in Figure 3 above) and multiple repeated transmissions of SIB1 can be one-to-one. The time-frequency domain relationship between the SIB1 scheduled by the MIB and the MIB can be pre-configured or agreed upon, or it can be indicated by the MIB. Option 2: In one SIB1 transmission cycle, a MIB transmission can be followed by multiple repeated SIB1 transmissions, or there can be no following SIB1 repeated transmissions. The advantage of this pattern design between the MIB and SIB1 is that it allows for more concentrated execution of multiple repeated SIB1 transmissions and MIB transmissions, thereby achieving network energy savings. Option 3: The number of subsequent SIB1 repetitions following the MIB can be dynamically indicated. This method is more flexible; however, its feasibility depends on whether different indications carried by the MIB affect the merging of multiple MIB repetitions, which needs to be considered.
[0401] It should be noted that the MIB is the main information block used for initial terminal access and initial synchronization, and it also carries information related to scheduling SIB1. This application does not exclude the use of other names besides MIB to describe the above functions.
[0402] In some implementations, the MIB may carry a SIB1 scheduling method indication, and the SIB1 scheduling method includes: 1) carrying SIB1 scheduling indication information through the first MIB, and 2) carrying SIB1 scheduling indication information through the first PDCCH.
[0403] In other words, whether SIB1 retransmissions are scheduled using PDCCH can be flexibly determined based on the MIB's indications. Furthermore, certain bits or codewords in the MIB can be used to indicate: 1) whether SIB1 is scheduled via PDCCH, or 2) whether the relevant PDCCH configuration indication information in the MIB for SIB1 scheduling is effective. Regarding 1), if the indication is that PDCCH scheduling is not used, the terminal receives or retransmits SIB1 according to the SIB1 scheduling-related indications in the MIB. Otherwise, the terminal needs to obtain the SIB1 scheduling information based on the PDCCH used for receiving SIB1. Regarding 2), if the relevant PDCCH configuration indication information in the MIB for SIB1 scheduling is indicated as effective, the terminal receives PDCCH based on the SIB1 scheduling PDCCH configuration in the MIB and then obtains SIB1 according to the PDCCH scheduling. Otherwise, the terminal receives or retransmits SIB1 according to the SIB1 scheduling-related indications in the MIB.
[0404] In some implementations, the MIB carries an indication of the length of the second time period (the transmission period of the system information block). By extending the transmission period length of SIB1, more transmissions and mergings of SIB1 are increased, ensuring transmission reliability and increasing coverage. For example, the default transmission period of SIB1 is 160ms, with 8 repeated transmissions within 160ms. By indicating that the transmission period of SIB1 is extended to 320ms, the MIB enables 16 repeated transmissions within 320ms, allowing for 16 SIB1 mergings. This increases the coverage of SIB1.
[0405] In some implementations, the MIB may also carry the activation or deactivation of additional first PDCCH transmission resource configurations; for example, in 2) the method of carrying SIB1 scheduling indication information through the first PDCCH, assuming the number of PDCCH repetitions that can be combined = N, where N is a standard predefined or MIB configuration. If the transmission period of SIB1 = T1, the first PDCCH is received in the default Type-0 CSS (i.e., without activating additional first PDCCH transmission resource configurations), and multiple first PDCCHs within period T1 can be combined. If the transmission period of SIB1 = T2, it is considered that there are also second-type Type-0 CSS PDCCHs available for combining (i.e., activating additional first PDCCH transmission resource configurations). The number of resources in the second-type Type-0 CSS is related to T2 / T1, or to T2 and N. Alternatively, if the indicated transmission period of SIB1 = T1, the PDCCH is received in the first-type Type-0 CSS, and multiple PDCCHs within period T1 can be combined. If the transmission period of SIB1 is T2, then it is assumed that there is a second type of Type-0 CSS PDCCH available for merging.
[0406] In some implementations, for LPWA terminals, PDCCH must be transmitted on the slot used for PDCCH repetition. Therefore, the improvement in this case is that the network-side equipment can flexibly indicate via MIB whether one or both sets of PDCCH resources are used for PDCCH repetition. The advantage of this is that coverage can be dynamically adjusted, and PDCCH resource scheduling is more flexible.
[0407] In this embodiment, a design is provided for a 6G LPWA terminal to obtain the first system information (SIB1) scheduling information and to address the repetitive transmission of SIB1. This design considers both low signaling overhead and, to a certain extent, flexibility in resource scheduling. Furthermore, it improves the reliability of system message blocks.
