Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of information processing, and in particular to an information reporting method, an information obtaining method, a terminal, a network device, a chip, a computer readable storage medium, a computer program product and a computer program. BACKGROUND

[0002] With the continuous evolution of wireless communication technology and the help of wireless communication technology, the Internet of Things (IOT) technology is developing rapidly. For example, the MTC (Machine-Type Communication) / eMTC (enhanced Machine-Type Communication) and NB-IoT (NarrowBand Internet of Things) series standards promoted by the 3GPP organization have become the candidate technical standards for 5G massive MTC (5G massive MTC) technology. These technologies also have some application scenario limitations. Since the design goal of MTC / eMTC and NB-IoT is to support some low data rate and high transmission delay applications, they cannot be applied in some Internet of Things scenarios that require relatively high rates, such as video monitoring in intelligent security and relatively low latency industrial applications. Therefore, in order to perfect the terminal system of the 5G massive MTC scenario, it is necessary to design an NR (New Radio) MTC terminal type that supports medium transmission rate and medium latency requirements and has a relatively low cost. The 3GPP calls this NR MTC terminal type an NR-light terminal. However, how to make the network know the characteristics of the terminal so that the network can make adaptive configuration is a problem that needs to be solved. SUMMARY

[0050] In order to enable more detailed understanding of the features and technical contents of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below, and the attached drawings are only used for reference and do not limit the embodiments of the present application.

[0051] The embodiments of the present application provide an information reporting method, as shown in the following Figure 2 The method comprises the following steps:

[0052] Step 21: The terminal sends feature information to the network device;

[0053] The feature information is sent in at least one of the following ways:

[0054] The feature information of the terminal is indicated through a first channel or a first signal;

[0055] The feature information of the terminal is carried in first information.

[0056] The embodiments of the present application also provide an information acquisition method, as shown in the following Figure 3 The method comprises the following steps:

[0057] Step 31: The network device receives the feature information sent by the terminal;

[0058] The feature information sent by the terminal is received in at least one of the following ways:

[0059] The feature information indicated by the terminal is received through a first channel or a first signal;

[0060] The feature information carried in the first information is received.

[0061] In the embodiments, the terminal can be an NR-terminal, or can be an NR-light terminal, of course, it can also be other types of terminals in IOT, which is not exhaustive here. The scheme provided in the embodiments can be applied to all types of terminals that can access the communication network, that is, all types of terminals can send corresponding feature information to the network device.

[0062] First, the feature information in the embodiments is described:

[0063] The feature information comprises at least one of the following:

[0064] the number of antennas or antenna ports of the terminal;

[0065] the transmission bandwidth supported by the terminal;

[0066] the subcarrier spacing supported by the terminal;

[0067] the number of BWPs supported by the terminal;

[0068] the BWP switching delay supported by the terminal;

[0069] the maximum number of HARQ processes supported by the terminal;

[0070] the maximum transport block (TB) size supported by the terminal;

[0071] the relevant parameters of PDCCH monitoring supported by the terminal;

[0072] the relevant parameters of the processing capability of the terminal;

[0073] the relevant parameters of the channel estimation capability of the terminal.

[0074] It should be noted that different terminals can contain different feature information, and the terminal determines the specific content of the feature information to be reported according to its own situation. In addition, the feature information contained by different terminals is one or more of the foregoing feature information.

[0075] Further, the specific content that each kind of feature information can contain can be seen from the following description:

[0076] The number of antennas or antenna ports of the terminal can include at least one of the following:

[0077] The number of antennas or antenna ports of the terminal;

[0078] The number of uplink transmission antennas or antenna ports of the terminal;

[0079] The number of downlink reception antennas or antenna ports of the terminal;

[0080] For example, the number of antennas or antenna ports possessed by different NR-light terminals can be 1, 2, or 4.

[0081] The number of uplink transmission antennas or antenna ports and the number of downlink reception antennas or antenna ports can be the same or different.

[0082] In the scheme provided by the embodiment, if the number of uplink and downlink antennas or antenna ports is the same, only the number of antennas or antenna ports can be reported, that is, the network side can default that the number of uplink and downlink antennas or antenna ports of the terminal is the same.

[0083] If not, the terminal can report the number of uplink antennas or antenna ports and the number of downlink receiving antennas or antenna ports respectively.

[0084] For example, for some special terminal scenarios, the number of uplink transmitting antennas or antenna ports and the number of downlink receiving antennas or antenna ports supported by the terminal can be different. For example, these terminals are mainly used to support uplink services such as video monitoring, and the rate requirement of uplink transmission data is much greater than the requirement of downlink download data, so a larger number of uplink antennas can be supported, and a smaller number of downlink receiving antennas can be supported, such as 4 uplink antennas and 2 downlink receiving antennas.

[0085] The transmission bandwidth supported by the terminal can include at least one of the following:

[0086] The transmission bandwidth supported by the terminal;

[0087] The uplink transmission bandwidth supported by the terminal;

[0088] The downlink transmission bandwidth supported by the terminal.

[0089] That is, the terminal can report the transmission bandwidth it supports, and at this time the network device can consider that the uplink and downlink transmission bandwidths of the terminal are the same.

[0090] In addition, if the uplink transmission bandwidth of the terminal is different from the downlink transmission bandwidth, the terminal feature information can include the uplink transmission bandwidth and the downlink transmission bandwidth supported by the terminal respectively.

[0091] Alternatively, for a specific subcarrier spacing, at least one of the transmission bandwidth, the uplink transmission bandwidth, and the downlink transmission bandwidth supported by the terminal.

[0092] NR-light can support a relatively narrow transmission bandwidth, such as 5MHz, 10MHz, or 20MHz.

[0093] Similarly, some terminals can support different uplink and downlink bandwidths, and the terminal can report the uplink bandwidth and the downlink bandwidth it supports, such as 10MHz downlink and 20MHz uplink.

[0094] The terminal supportable subcarrier spacing can be: the terminal supportable subcarrier spacing, which can not distinguish between channels, and can be in terminal units. Alternatively, it can be the terminal supportable subcarrier spacing of the synchronization channel and / or data channel. That is, the subcarrier spacing corresponding to the synchronization channel can be the same as or different from the subcarrier spacing of the data channel. If they are the same, the terminal supportable subcarrier spacing can be reported without distinction; if they are different, the terminal supportable subcarrier spacing of the synchronization channel and the data channel can be reported, or only one of them can be reported, and the rest is not enumerated.

[0095] The number of terminal supportable bandwidth parts (BWP, BandWidth Part) can include at least one of the following:

[0096] The number of terminal supportable BWP with different bandwidths; wherein if only one bandwidth is supported, the terminal supportable bandwidth and / or the number of BWP can be reported; if multiple bandwidths are supported, the multiple bandwidths and / or the number of BWP supported by the terminal for each bandwidth can be reported.

[0097] The number of terminal supportable BWP with different subcarrier spacings; wherein if there is only one subcarrier spacing, the terminal can report the supportable subcarrier spacing and / or the number of BWP. If multiple subcarrier spacings are supported, the terminal supportable subcarrier spacing and / or the corresponding number of BWP can be reported.

[0098] The number of terminal supportable UL (uplink, UpLink) BWP; that is, if the number of terminal supportable UL and DL BWP is different, the terminal can only report the number of supportable UL BWP.

[0099] The number of terminal supportable UL BWP with different bandwidths; it can be understood that the terminal can support multiple bandwidth UL BWP, or support multiple bandwidth UL BWP and the number of different bandwidth UL BWP, or only the number of UL BWP corresponding to the terminal supportable multiple bandwidth UL BWP.

[0100] The number of terminal supportable UL BWP with different subcarrier spacings; it can be understood that the terminal can support multiple subcarrier spacings, and the terminal supportable different subcarrier spacings and / or the number of UL BWP corresponding to different subcarrier spacings can be reported.

[0101] The bandwidth size and / or subcarrier spacing of the BWP supported by the terminal; the terminal can report the subcarrier spacing supported by itself to the network device, if the terminal supports one subcarrier spacing, it reports one, if it supports multiple, it needs to report multiple. In addition, if the BWP bandwidth size supported by each subcarrier spacing is the same, only one BWP bandwidth can be reported, if the BWP bandwidth sizes corresponding to different subcarrier spacings are different, the terminal needs to report the multiple subcarrier spacings it supports and the BWP bandwidth size corresponding to each subcarrier spacing. Further, if among the multiple subcarrier spacings supported by the terminal, at least part of the subcarrier spacings correspond to multiple BWP bandwidth sizes, the terminal can also include the number of BWP bandwidths corresponding to each subcarrier spacing and the corresponding size.

[0102] The number of DL (DownLink) BWP supported by the terminal; that is, if the number of UL and DL BWP supported by the terminal is different, the terminal can only report the number of DL BWP it supports.

[0103] The number of DL BWP with different bandwidths supported by the terminal; it can be understood that the terminal can support multiple bandwidths, and then report the bandwidth of the different DL BWP and / or the number of DL BWP with different bandwidths.

[0104] The number of DL BWP with different subcarrier spacings supported by the terminal; it can be understood that the terminal can support multiple subcarrier spacings, and then report the different subcarrier spacings supported by the terminal and / or the number of DL BWP corresponding to different subcarrier spacings.

[0105] The more the number of BWP (or BWP configuration) supported by the terminal or the more the number of BWP bandwidths supported by the terminal, the more complex the design of the terminal, such as supporting different bandwidth sizes of radio frequency and / or baseband filters for different bandwidth BWP. Therefore, for some simple application scenarios of the terminal, a limited number of BWP or a limited BWP bandwidth size can be supported.

[0106] It should be understood that the specific content of the number of BWP supported by the terminal described above can include one or more of the foregoing, and different terminals can report according to their actual situation. For example, the terminal can report that the number of UL BWP supported by the terminal is 2, at this time if the number of DL BWP is not reported, it can be defaulted that the number of UL and DL BWP is the same and is also 2. Or, the terminal feature information can include that the terminal can support 2 UL BWP and 4 DL BWP. Here, it is not exhaustive.

[0107] The latency of the BWP switching supported by the terminal can include:

[0108] The latency of the BWP switching supported by the terminal;

[0109] The latency of the UL BWP switching supported by the terminal; and / or

[0110] The latency of the DL BWP switching supported by the terminal.

[0111] The BWP switching can involve the adjustment of the radio frequency parameters of the terminal, such as the bandwidth size and the frequency location, or the adjustment of the baseband parameters of the terminal, such as the configuration of different PDCCH search spaces. Different NR-light terminals can support different latencies of the BWP switching. Some scenarios that are not sensitive to the latency can support a larger latency of the BWP switching, so as to relax the design requirements of the terminal and reduce the cost of the terminal.

[0112] Similarly, if the latency of the UL BWP switching supported by the terminal is the same as the latency of the DL BWP switching, only the latency of the BWP switching supported by the terminal can be reported; or only the latency of the UL or DL BWP switching can be reported. If the latency of the UL BWP switching supported by the terminal is different from the latency of the DL BWP switching, both the latency of the UL BWP switching and the latency of the DL BWP switching can be included in the feature information.

[0113] The maximum number of HARQ processes supported by the terminal can be at least one of the following:

[0114] The maximum number of HARQ processes supported by the terminal;

[0115] The maximum number of UL HARQ processes supported by the terminal;

[0116] The maximum number of DL HARQ processes supported by the terminal.

[0117] It should be noted that the number of HARQ processes affects the peak rate and the transmission latency of the data transmission of the terminal. The more the number of HARQ processes is, the higher the peak rate is and the lower the transmission latency is. However, the more the number of HARQ processes is, the larger the chip area of the terminal is, and thus the cost of the terminal is increased.

[0118] For scenarios that are not sensitive to the data transmission latency or have a low requirement on the data rate, a smaller number of HARQ processes can be supported, so as to reduce the cost of the terminal.

[0119] Similarly, if the maximum UL HARQ process number that the terminal can support is the same as the maximum DL HARQ process number, only the maximum UL HARQ process number that the terminal can support can be reported; or, only the maximum HARQ process number can be reported. If the maximum UL HARQ process number that the terminal can support is different from the maximum DL HARQ process number, both the maximum UL HARQ process number and the maximum DL HARQ process number can be included in the feature information.

[0120] The maximum TB (Transport Block) size that the terminal can support can include at least one of the following:

[0121] The maximum TB size that the terminal can support;

[0122] The maximum UL TB size that the terminal can support;

[0123] The maximum DL TB size that the terminal can support.

[0124] Similarly, if the maximum UL TB size that the terminal can support is the same as the maximum DL TB size, only the maximum UL TB size that the terminal can support can be reported; or, only the maximum TB size can be reported.

[0125] If the maximum UL TB size that the terminal can support is different from the maximum DL TB size, both the maximum UL TB size and the maximum DL TB size can be included in the feature information.

[0126] The PDCCH (Physical Downlink Control CHannel) monitoring related parameters that the terminal can support include at least one of the following:

[0127] The number of PDCCH blind detections in a unit time; wherein, the unit time can be a time length set according to actual conditions, such as 1 ms or 1 slot, and of course can be longer or shorter, which will not be enumerated here.

[0128] The minimum interval of adjacent PDCCH monitoring time points supported;

[0129] The types of PDCCH aggregation levels supported; for example, the aggregation level of PDCCH can be 1, 2, 4, 8 CCEs, and the terminal selects one that it can support according to its own conditions.

[0130] The number of PDCCH candidate positions for each aggregation level supported;

[0131] The number of supported PDCCH CORESET (control resource set) configurations;

[0132] The number of supported PDCCH search space sets.

[0133] For example, some terminals can support a number of 44 PDCCH blind detection attempts within one ms, but some terminals can only support a number of 22 PDCCH blind detection attempts, thereby reducing the processor requirements and costs of the terminals.

[0134] The terminal processing capability related parameters, such as the terminal processing capability related to control channels or data channels, such as the timing difference between PDCCH and PDSCH (Physical Downlink Share CHannel) / PUSCH (Physical Uplink Share CHannel), or the timing difference between PDSCH and PUSCH. For example, some terminals can support a longer timing difference of the foregoing type, thereby reducing the processor requirements and costs of the terminals. Of course, there can be other types of terminal processing capability related parameters, which are not enumerated here, and any parameter that can be used to indicate the terminal processing capability in the related art can be included in the embodiments of the present application.

[0135] The channel estimation capability related parameters of the terminal. For example, the number of non-overlapping CCEs within one time unit (such as within 1 ms, or within 1 slot).

[0136] In combination with the foregoing, the feature information reported by different terminals can be different or the same, and is determined according to the situation of the terminal itself. For example, the feature information to be reported by terminal A can include: the number of supported uplink transmission antennas is 2, the number of supported downlink reception antennas is 4, the supported transmission bandwidth is 5 MHz, the number of supported BWP is 2, and the like. The feature information to be reported by terminal B can include: the number of supported antennas is 4, the supported uplink transmission bandwidth is 5 MHz, the supported downlink transmission bandwidth is 10 MHz, the number of supported PDCCH aggregation types is 2, and the like. The embodiments are not enumerated here.

[0137] It should be noted that the foregoing reported terminal features are only examples, and the specific types and numbers of features are not limited.

[0138] Based on the foregoing description of the feature information, the specific processing of how the terminal indicates its feature information to the network device is described in combination with multiple examples as follows:

[0139] Example 1, by PRACH resource group, to implicitly indicate the corresponding feature information of the network device. That is, PRACH resource grouping can be used to indicate different terminal feature groupings. The network can configure multiple groups of PRACH resources, and each group of resource groupings corresponds to a group of terminal characteristics.

[0140] Specifically as follows:

[0141] The terminal transmits PRACH on the first resource group corresponding to the random access channel PRACH to indicate that the feature information is a first feature information group corresponding to the first resource group;

[0142] Among the first feature information group, there is at least one feature information;

[0143] The first resource group corresponding to the PRACH is one of at least one resource group corresponding to the PRACH; different resource groups in the at least one resource group corresponding to the PRACH correspond to different feature information groups; wherein each feature information group contains at least one feature information, and different feature information groups contain at least partially different feature information.

[0144] Correspondingly, the network device receives the PRACH transmitted by the terminal on the first resource group corresponding to the random access channel PRACH; and the network device determines that the feature information is a corresponding first feature information group according to the first resource group corresponding to the PRACH.

[0145] Each feature information group contains one or more of the aforementioned feature information. It can be all of the aforementioned feature information, or it can be part of the feature information.

[0146] Further, the terminal determines that different resource groups in the at least one resource group corresponding to the PRACH correspond to different feature information groups according to the first configuration information;

[0147] Among them, the first configuration information is preset, or sent by the network device to the terminal.

[0148] Among them, the network device can send the terminal through system information such as SIB, MIB, etc. to the terminal; or, through MAC CE to send to the terminal; or, through RRC signaling to configure to the terminal, which is not listed here.

[0149] It should be understood that the first configuration information is also saved at the network device side, which can be preset at the network device side according to the protocol, or can be generated by the network device according to the protocol. If it is generated by the network device, the network device needs to send the first configuration information to the terminal.

[0150] The first configuration information can specifically include: at least one resource group of PRACH, and each PRACH corresponds to a feature information group corresponding to the resource group.

[0151] For example, the definition of the specific features of each group of terminal features in the multiple groups of terminal features can be predefined or network preconfigured. For example, three groups of terminal feature information are predefined as follows:

[0152] Feature information group 1: supports 2 receive antennas, supports a terminal bandwidth of 5 MHz, supports 2 BWP configurations, and supports 4 HARQ processes.

[0153] Feature information group 2: supports 4 receive antennas, supports a terminal bandwidth of 20 MHz, supports 4 BWP configurations, and supports 8 HARQ processes.

[0154] Feature information group 3: supports 4 receive antennas, supports a terminal bandwidth of 10 MHz for downlink reception and 20 MHz for uplink transmission, supports 2 BWP configurations, and supports 4 HARQ processes.

[0155] Therefore, in the first configuration information, the resource group 1 corresponds to the feature information group 1, the resource group 2 corresponds to the feature information group 2, and the resource group 3 corresponds to the feature information group 3.

[0156] The aforementioned first resource group can be one of the one or more resource groups, which is referred to as the first resource group herein.

[0157] If the first configuration information only includes one resource group and the corresponding feature information group, the selection is not required, and the resource group indicated in the first configuration information is directly used as the first resource group.

[0158] If the first configuration information includes two or more resource groups, the processing of the terminal can further include:

[0159] According to the feature information of the terminal, a first resource group that matches the feature information to be transmitted is selected from the multiple resource groups, and then the PRACH is transmitted in the first resource group.

[0160] Correspondingly, the network device receives the PRACH transmitted by the terminal on the resource corresponding to the first resource group, and then determines the first feature information group of the terminal according to the first resource group. Further, the network device determines the at least one feature information reported by the terminal according to the first feature information group.

[0161] More specifically, the multiple resource groups can not include all the feature information to be reported by the terminal, and then a first resource group that at least partially matches all the feature information to be reported by the terminal is selected from the multiple resource groups.

[0162] Further to the foregoing example, if the terminal is to report feature information of feature information group 2, then the terminal can use resource group 2 corresponding to feature information group 2 as the foregoing first resource group, and then transmit PRACH in the first resource group. The network device receives PRACH in the first resource group, and then determines that the terminal reports feature information group 2, and determines the feature information of the terminal based on the content of feature information group 2.

[0163] Example 2: Implicitly indicate the feature information corresponding to the network device through preamble. That is, different terminal feature groups can be indicated by using preamble groups. The network can configure multiple preamble groups, and each preamble group corresponds to a terminal feature group.

[0164] Specifically as follows:

[0165] In the process of initiating random access by the terminal, the terminal indicates that the feature information of the terminal is a second feature information group corresponding to a first preamble group by sending the first preamble group to the network device.

[0166] The second feature information group contains at least one feature information.

[0167] The first preamble group is one of at least one preamble group, different preamble groups in the at least one preamble group correspond to different feature information groups, each feature information group contains at least one feature information, and different feature information groups contain at least partially different feature information.

[0168] Correspondingly, in the process of random access, the network device receives the first preamble group sent by the terminal, and determines the second feature information group corresponding to the terminal according to the first preamble.

[0169] The terminal determines that different preamble groups in the at least one preamble group correspond to different feature information groups according to the second configuration information.

[0170] The second configuration information is preset or sent by the network device to the terminal.

[0171] The network device can send the second configuration information to the terminal through system information such as SIB, MIB, or MAC CE, or through RRC signaling, which is not listed here.

[0172] It needs to be understood that the second configuration information is also saved at the network device side, which can be preset at the network device side according to a protocol, or can be generated by the network device according to a protocol. If the network device generates the second configuration information, the network device needs to send the second configuration information to the terminal.

[0173] The second configuration information can specifically include: at least one preamble group, and each preamble group corresponds to a feature information group.

[0174] The definition of the specific feature of each group of terminal features can be predefined or preconfigured by the network. For example, three groups of terminal features are predefined:

[0175] The first group of terminal features is a terminal supporting 1 receiving antenna, supporting a terminal bandwidth of 5MHz; supporting 2 kinds of BWP configuration; and supporting 4 HARQ process numbers.

[0176] The second group of terminal features is a terminal supporting 2 receiving antennas, supporting a terminal bandwidth of 20MHz; supporting 4 kinds of BWP configuration; and supporting 8 HARQ process numbers.

[0177] The third group of terminal features is a terminal supporting 2 receiving antennas, supporting a downlink receiving bandwidth of 10MHz and an uplink transmitting bandwidth of 20MHz; supporting 2 kinds of BWP configuration; and supporting 4 HARQ process numbers.

[0178] For example, the following can be determined through the content of the second configuration information:

[0179] If the preamble set available for the terminal is [0 35], three groups of preamble subsets can be used to correspond to the three groups of terminal features respectively, for example, the preamble set [0 11] corresponds to the first group of terminal features, the preamble set

[1223] corresponds to the second group of terminal features, and the preamble set [24 35] corresponds to the third group of terminal features.

[0180] Further, the first preamble group can be one of one or more preamble groups, which is only referred to as the first preamble group here.

[0181] If the second configuration information only contains one preamble group and the corresponding feature information group, no selection is needed, and the preamble group indicated in the second configuration information is directly taken as the first preamble group.

[0182] If the second configuration information contains two or more preamble groups, the processing of the terminal can further include:

[0183] According to the characteristic information of the terminal, a first preamble group is selected from the plurality of preamble groups, and the first preamble group is transmitted. Correspondingly, the network device receives the first preamble group transmitted by the terminal, and determines the second characteristic information group of the terminal according to the first preamble group. Then, the network device can determine at least one characteristic information reported by the terminal according to the second characteristic information group.

[0184] More specifically, the plurality of preamble groups may not contain all the characteristic information to be reported by the terminal, and then a first preamble group at least partially matching the all characteristic information to be reported by the terminal is selected from the plurality of preamble groups.

[0185] That is, the terminal selects a preamble in the preamble set (or preamble group) corresponding to the terminal characteristic when initiating random access. By combining the preamble grouping and the terminal characteristic corresponding to the preamble grouping, the network can determine the terminal characteristic of the terminal initiating random access when receiving the preamble, and then reasonably allocate resources for subsequent data transmission of the terminal.

[0186] In this example, the first preamble group can be transmitted in the following ways:

[0187] The first preamble group can be carried by a shared random access occasion (RO) or an independent RO.

[0188] It should be understood that the preamble is carried (or transmitted) in the RO. There can be 64 preambles in one RO.

[0189] Correspondingly, the network device receives the first preamble group in the following ways: receiving the first preamble group carried by a shared random access occasion (RO) or receiving the first preamble group carried by an independent RO.

[0190] That is, the preamble used to indicate the terminal characteristic can be shared with the normal NR terminal in the random access occasion (RO, RACH occasion) or can be configured with an independent RO.

[0191] If the independent RO is configured, the transmission can be performed according to the independent RO, which is not described here.

[0192] The present example mainly describes the sharing RO mode:

[0193] In the case of carrying the first preamble group by the shared RO,

[0194] The method further comprises:

[0195] The terminal receives third configuration information;

[0196] Among them, the third configuration information contains: the set of at least one preamble configured by the network device for the terminal for contention random access CBRA; and at least one preamble group for indicating the feature information of the terminal.

[0197] Correspondingly, the network device sends the third configuration information to the terminal.

[0198] Here, the third configuration information can be carried by RRC signaling, MAC CE, or can be carried by system broadcast information.

[0199] The set of at least one preamble for contention random access CBRA can be understood as the set of preambles occupied by four-step random access,

[0200] For example, see Figure 4 For the sharing RO mode, the preamble set for reporting the terminal feature can be configured outside the preamble set used to configure the normal NR terminal to perform CBRA (contention based random access), that is, outside the preamble set used for four-step random access, and can be configured close to and after the preamble set used for CBRA (contention based random access) of the normal NR terminal to report the preamble set of the terminal feature.

[0201] In addition, on the basis of the foregoing, the third configuration information further includes: the set of at least one preamble configured by the network device for the terminal for two-step random access.

[0202] For example, see Figure 5, if the system is also configured with 2-step RACH and the preambles allocated for 2-step RACH share ROs with normal NR terminals, the preamble set for reporting the terminal features can be configured outside the preamble set occupied by the traditional CBRA preamble set for configuring normal NR terminals (that is, the set composed of at least one preamble for four-step random access) and the set composed of at least one preamble for two-step random access, for example, at least one preamble group for indicating the feature information of the terminal can be configured close to and after the preamble set allocated for 2-step RACH.

[0203] Further, the RO shared by the preamble for indicating the terminal feature and the normal NR terminal can be part of all ROs used by the normal NR terminal. Then the method further comprises:

[0204] The terminal receives fourth configuration information; wherein the fourth configuration information contains at least one RO that can be used to carry the first preamble Preamble group.

[0205] Correspondingly, the network device sends fourth configuration information to the terminal; wherein the fourth configuration information contains at least one RO that can be used to carry the first preamble Preamble group.

[0206] That is, the network device can send fourth configuration signaling to indicate which ROs among all ROs used by the normal NR terminal are also used to carry the preamble for indicating the terminal feature.

[0207] It should be noted that the fourth configuration information can be carried in the same signaling as the third configuration information, for example, it can be contained in two IEs in the same signaling. Of course, the fourth configuration information can also be sent in two signalings with the third configuration information, which is not limited here.

[0208] Example 3, different from the foregoing examples 1 and 2, this example can be explicitly indicated to the network device through the first information corresponding to the feature information.

[0209] Specifically:

[0210] In one way, the terminal carries at least one feature information of the terminal in the first information.

[0211] That is, the terminal carries all the feature information to be reported in the first information in an enumerated manner, for example, the number of supported uplink transmission antennas is 2, the number of supported downlink receiving antennas is 4, the supported transmission bandwidth is 5MHz, the number of supported BWP is 2, and so on. Then, the network device directly obtains the feature information reported by the terminal through the received first information.

[0212] In another way, the terminal carries the identification of the feature information group in the first information, wherein the identification of the feature information group is used to indicate at least one feature information contained in the feature information group. Correspondingly, the network device receives the identification of the feature information group carried in the first information by the terminal.

[0213] That is, the first information can only contain one identification, through which the corresponding feature information group can be reported. Correspondingly, the network device can determine the feature information group reported by the terminal according to the identification carried in the first information, and further determine at least one feature information contained.

[0214] The first information is one of the following:

[0215] The PUSCH of MSG3 of four-step random access, the PUSCH of MSG A in two-step random access, RRC signaling, and MAC CE signaling.

[0216] Further, in this way, the at least one feature information corresponding to the identification of the feature information group can be pre-configured by the terminal and the network device.

[0217] That is, the terminal and the network device can pre-group the terminal features. The terminal reports the group identification of the terminal features.

[0218] Further, the above two ways can be used alone or in combination. For example, if the feature information group does not contain all the feature information, the terminal can report part of the feature information through the identification of the feature information group, and report the remaining feature information separately.

[0219] For example, the feature information to be reported by the terminal is 10, of which 6 can have corresponding feature information groups. The terminal carries the identification of the 6 feature information groups in the first information. The remaining 4 feature information can be carried and reported in the first information.

[0220] For example, the identification of the feature information group 1 can be carried in the first information, and each parameter of the terminal feature, such as the number of supported terminal antennas, the number of ports, the terminal bandwidth, the number of supported BWP, and the like, can also be carried.

[0221] The foregoing examples 1, 2, and 3 can be used alone, and in some possible implementations, the foregoing multiple ways of reporting terminal features can also be used in combination. For example, the PRACH channel or preamble can be used to report part of the terminal features, such as the number of supported antennas / ports, and RRC signaling, that is, the first information, can be used to report one or more features, such as the supported bandwidth, the number of BWPs, and the number of HARQ processes.

[0222] For example, examples 1 and 3 can be used in combination. The terminal takes the feature information in the feature information group corresponding to the PRACH resource group included in the first configuration information from all the feature information to be reported as the first feature information group, instructs the network device to the first feature information group corresponding to the first resource group of the PRACH based on the first feature information group, so that the network device determines the feature information group according to the resource group, and further determines the feature information reported by the terminal. Then, the terminal reports the remaining feature information (which can be referred to as second part feature information) of the feature information to be reported other than the first feature information group through the first information.

[0223] Further, the terminal can match the second part feature information with the preset feature information group identifier and the at least one feature information corresponding thereto, report part of the second part feature information by carrying the identifier of the feature information group corresponding thereto through the first information, and finally report another part of the second part feature information through the first information.

[0224] For another example, examples 2 and 3 can be used in combination.

[0225] The terminal takes the feature information in the feature information group corresponding to the preamble group included in the second configuration information from all the feature information to be reported as the feature information group A, instructs the network device to the feature information group A corresponding to the first preamble group based on the feature information group A, so that the network device determines the feature information group A and the at least one feature information corresponding thereto according to the first preamble group. Then, the terminal reports the remaining feature information (which can be referred to as third part feature information) of the feature information to be reported other than the feature information group A through the first information.

[0226] Further, the terminal can match the third part feature information with the preset feature information group identifier and the at least one feature information corresponding thereto, report part of the third part feature information by carrying the identifier of the feature information group corresponding thereto through the first information, and finally report another part of the third part feature information through the first information.

[0227] Or, examples 1, 2, 3 can be further combined, for example, the terminal determines the feature information to be reported; then determines the feature information group 1 contained in the feature information group corresponding to the PRACH resource group according to the first configuration information, and determines the feature information group 2 contained in the feature information corresponding to the preamble group according to the second configuration information (the feature information groups 1 and 2 can have different overlaps, but if they are completely overlapped, only one way can be selected for reporting, as long as there are some different feature information, both can be used);

[0228] The terminal determines the corresponding PRACH resource group 1 based on the feature information group 1, and performs PRACH transmission through the PRACH resource group 1; correspondingly, the network device determines that the corresponding feature information group is the feature information group 1 after receiving the PRACH on the PRACH resource group 1, and then obtains the feature information corresponding to the terminal;

[0229] The terminal determines the corresponding preamble group 2 based on the feature information group 2, and transmits the preamble group 2 on the RO (in the random access process); correspondingly, the network device determines that the corresponding feature information group is the feature information group 2 after receiving the preamble group 2, and then the network device obtains the feature information corresponding to the terminal.

[0230] Then, the terminal reports the remaining feature information in the feature information to be reported, except for the feature information groups 1 and 2, to the network device through the first information (such as RRC signaling); correspondingly, the network device obtains the corresponding feature information through the RRC signaling.

[0231] Finally, the embodiment also provides a way for different types of terminals, such as NR-Light terminals, which can also indicate the corresponding related information through the preamble, wherein the related information can be information other than the aforementioned feature information. For example, the related information can be the capability, type, or capability level, category, etc. of the terminal, which is only used as an example and is not limited to the related information. In fact, there can be other related information, which is not exhaustively listed in this embodiment.

[0232] That is, the other related information of the terminal can also be implicitly indicated through the preamble (preamble).

[0233] Specifically as follows:

[0234] In the process of initiating random access by the terminal, the terminal indicates that the feature information of the terminal is at least one related information by sending a second preamble Preamble / or a second preamble group to the network device.

[0235] The second preamble / or the second preamble group is one of at least one preamble or preamble group; different preamble groups in the at least one preamble group correspond to at least partially different related information, or different preambles correspond to at least partially different related information.

[0236] Correspondingly, in the process of random access, the network device receives the second preamble / or the second preamble group sent by the terminal; and the network device determines at least one related information corresponding to the terminal according to the second preamble / or the second preamble group.

[0237] The terminal determines that different preamble groups in the at least one preamble group correspond to different related information according to the fifth configuration information; or determines that different preambles correspond to different related information.

[0238] The fifth configuration information is preset or sent by the network device to the terminal.

[0239] The network device sends the fifth configuration information to the terminal, which can be configured to the terminal through system information such as SIB, MIB, etc.; or sent to the terminal through MAC CE; or configured to the terminal through RRC signaling, which is not listed here.

[0240] It should be understood that the fifth configuration information is also saved on the network device side, which can be preset on the network device side according to the protocol, or generated by the network device according to the protocol. If it is generated by the network device, the network device needs to send the fifth configuration information to the terminal.

[0241] The fifth configuration information can specifically include: at least one preamble group, each preamble group corresponding to related information; or at least one preamble, each preamble corresponding to related information.

[0242] For example, the following can be determined by the content of the fifth configuration information:

[0243] If the preamble set available to the terminal is [0 35], three preamble subsets corresponding to the three groups of related information can be used, for example, the preamble set [1 13] corresponds to the first group of related information, the preamble set [14 25] corresponds to the second group of related information, and the preamble set [18 31] corresponds to the third group of related information.

[0244] If only one preamble group and its corresponding related information group are contained in the fifth configuration information, no selection is needed, and the preamble group indicated in the fifth configuration information is directly taken as the second preamble group.

[0245] If two or more preamble groups are contained in the fifth configuration information, the processing of the terminal can further include:

[0246] According to the related information to be transmitted, a second preamble group or a second preamble that matches the related information to be transmitted is selected from the multiple preamble groups or multiple preambles, and then the second preamble group or the second preamble is transmitted.

[0247] Correspondingly, when the network device receives the second preamble group or the second preamble sent by the terminal, the network device can determine the second group of related information of the terminal corresponding to the second preamble group or the second preamble according to the fifth configuration information, and then the network device can determine the at least one related information reported by the terminal according to the second group of related information.

[0248] The second preamble group or the second preamble can be transmitted in the following ways:

[0249] The second preamble group or the second preamble can be carried by a shared random access occasion (RO) or by an independent RO.

[0250] It should be understood that the preamble is carried (or transmitted) in the RO, and there can be 64 preambles in one RO.

[0251] Correspondingly, the network device receives the second preamble group or the second preamble in the following ways: receiving the second preamble group or the second preamble carried by a shared random access occasion (RO) or receiving the second preamble group or the second preamble carried by an independent RO.

[0252] That is, the preamble used to indicate the related information can be shared with the normal NR terminal in the random access occasion (RO, RACH occasion) or can be configured with an independent RO.

[0253] If the independent RO is configured, the transmission can be performed according to the independently configured RO, which is not described herein.

[0254] The present example mainly describes the way of sharing RO:

[0255] In the case of carrying the second preamble group or the second preamble by the shared RO,

[0256] The method further comprises:

[0257] The terminal receives the sixth configuration information;

[0258] Among the sixth configuration information, there is at least one preamble group or preamble for indicating relevant information.

[0259] It should also be understood that the sixth configuration information can also include at least part of the content contained in the third configuration information in the aforementioned example 2, such as, it can also include:

[0260] The network device configures the terminal with a set composed of at least one preamble for competing for random access CBRA, and / or at least one preamble group for indicating the feature information of the terminal. Here, no longer elaborated.

[0261] Correspondingly, the network device sends the sixth configuration information to the terminal.

[0262] Here, the sixth configuration information can be carried by RRC signaling, MAC CE, or can be carried by system broadcast information.

[0263] In addition, on the basis of the foregoing, the sixth configuration information further includes: the set composed of at least one preamble for two-step random access configured by the network device for the terminal.

[0264] Further, the preamble for indicating the relevant information of the terminal can be part of all ROs used by the normal NR terminal. Then the method further comprises:

[0265] The terminal receives the seventh configuration information; among the seventh configuration information, there is at least one RO that can be used to carry the second preamble group or the second preamble.

[0266] It should be pointed out that the seventh configuration information can be carried in the same signaling as the sixth configuration information, such as, it can be contained in two IEs in the same signaling, of course, the seventh configuration information can also be sent with the sixth configuration information in two signals, which is not limited here.

[0267] It can be seen that by using the above scheme, the terminal can report the corresponding feature information to the network device. In this way, the network device can obtain the corresponding feature information of the terminal, and then facilitate the network device to make corresponding configuration or operation for the terminal based on the feature information of the terminal, thereby ensuring that the terminal performs operations in line with its own characteristics in the network, so that the terminal works normally in the communication system.

[0268] The embodiment of the present application provides a terminal, as shown in the figure, comprising: Figure 6

[0269] The first communication unit 61 sends feature information to the network device;

[0270] The feature information is sent in at least one of the following ways:

[0271] The feature information of the terminal is indicated through the first channel or the first signal;

[0272] The feature information of the terminal is carried in the first information.

[0273] The embodiment of the present application also provides a network device, as shown in the figure, comprising: Figure 7

[0274] The second communication unit 71 receives the feature information sent by the terminal;

[0275] The feature information sent by the terminal is received in at least one of the following ways:

[0276] The feature information indicated by the terminal is received through the first channel or the first signal;

[0277] The feature information carried in the first information is received.

[0278] First, the feature information in the embodiment is described:

[0325] The minimum interval of supported adjacent PDCCH monitoring occasions;

[0328] The number of supported PDCCH CORESET (Control Resource Set) configurations;

[0329] The number of supported PDCCH search space set (search space set).

[0330] Parameters related to the processing capability of the terminal, such as the terminal's processing capability related to control channels or data channels, such as the timing difference between PDCCH and PDSCH (Physical Downlink Share CHannel) / PUSCH (Physical Uplink Share CHannel), or the timing difference between PDSCH and PUSCH. For example, some terminals can support longer timing differences of the foregoing types, thereby reducing the processor requirements and costs of the terminal.

[0331] It should be noted that the foregoing reported terminal features are only examples, and the specific types and numbers of features are not limited.

[0332] Based on the foregoing description of the feature information, the following examples will explain how the terminal indicates its feature information to the network device:

[0333] Example 1: Implicitly indicate the corresponding feature information of the network device through the resource group of PRACH. That is, different terminal feature groups can be indicated by PRACH resource grouping. The network can configure multiple groups of PRACH resources, and each group of resource groups corresponds to a group of terminal characteristics.

[0334] Specifically as follows:

[0335] The first communication unit 61 of the terminal transmits PRACH on the first resource group corresponding to the random access channel PRACH, indicating that the feature information is a first feature information group corresponding to the first resource group;

[0336] The first characteristic information set includes at least one characteristic information.

[0337] The first resource set corresponding to the PRACH is one of at least one resource set corresponding to the PRACH; different resource sets in the at least one resource set corresponding to the PRACH correspond to different characteristic information sets; each characteristic information set includes at least one characteristic information, and different characteristic information sets include at least partially different characteristic information.

[0338] Correspondingly, the second communication unit 71 of the network device receives the PRACH transmitted by the terminal on the first resource set corresponding to the random access channel PRACH; the network device further includes a second processing unit 72 configured to determine the characteristic information as a corresponding first characteristic information set according to the first resource set corresponding to the PRACH.

[0339] Each characteristic information set includes one or more of the characteristic information. All of the characteristic information can be included, or part of the characteristic information can be included.

[0340] Further, the terminal further includes a first processing unit 62 configured to determine, according to first configuration information, that different resource sets in the at least one resource set corresponding to the PRACH correspond to different characteristic information sets.

[0341] The first configuration information is preset or sent by the network device to the terminal.

[0342] Example 2: The characteristic information corresponding to the network device is implicitly indicated by a preamble. That is, preamble grouping can be used to indicate different terminal characteristic groups. The network can configure multiple groups of preambles, and each group of preamble groups corresponds to a group of terminal characteristics.

[0343] Specifically as follows:

[0344] The first communication unit 61 of the terminal, in the process of initiating random access, indicates, by sending a first preamble group to the network device, that the characteristic information of the terminal is a second characteristic information set corresponding to the first preamble.

[0345] The second characteristic information set includes at least one characteristic information.

[0346] The first Preamble group is one of at least one Preamble group; different Preamble groups in the at least one Preamble group correspond to different characteristic information groups; each characteristic information group contains at least one characteristic information, and different characteristic information groups contain at least partially different characteristic information.

[0347] Correspondingly, in the process of random access, the second communication unit 71 of the network device receives the first Preamble group sent by the terminal; the second processing unit 72 of the network device determines the second characteristic information group corresponding to the terminal according to the first Preamble;

[0348] The first processing unit 62 of the terminal determines that different Preamble groups in the at least one Preamble group correspond to different characteristic information groups according to the second configuration information;

[0349] The second configuration information is preset or sent by the network device to the terminal.

[0350] The network device can send the terminal through system information such as SIB, MIB, etc. to configure the terminal; or send the terminal through MAC CE; or configure the terminal through RRC signaling, which is not listed here.

[0351] The second configuration information can specifically include: at least one Preamble group, each Preamble group corresponding to a resource group corresponding to a characteristic information group.

[0352] In this example, the first communication unit 61 can send the first Preamble group in the following ways:

[0353] The first Preamble group is carried by a shared random access occasion RO, or the first Preamble group is carried by an independent RO.

[0354] Correspondingly, the second communication unit 71 of the network device receives the first Preamble group in the following ways: receiving the first Preamble group carried by a shared random access occasion RO, or receiving the first Preamble group carried by an independent RO.

[0355] This example mainly describes the shared RO mode:

[0356] In the case of carrying the first Preamble group by a shared RO,

[0357] The first communication unit 61 of the terminal receives third configuration information.

[0358] The third configuration information includes: a set of at least one preamble configured by the network device for the terminal to contend for random access CBRA; and at least one preamble group indicating the feature information of the terminal.

[0359] Correspondingly, the second communication unit 71 of the network device sends the third configuration information to the terminal.

[0360] Here, the third configuration information can be carried by RRC signaling, MAC CE, or can be carried by system broadcast information.

[0361] In addition, on the basis of the foregoing, the third configuration information further includes: a set of at least one preamble configured by the network device for the terminal to contend for random access CBRA.

[0362] Further, the preamble used to indicate the features of the terminal and shared with the normal NR terminal can be part of all ROs used by the normal NR terminal. Then the first communication unit 61 of the terminal receives fourth configuration information; wherein the fourth configuration information includes: at least one RO that can be used to carry the first preamble Preamble group.

[0363] Correspondingly, the second communication unit 71 of the network device sends the fourth configuration information to the terminal; wherein the fourth configuration information includes: at least one RO that can be used to carry the first preamble Preamble group.

[0364] Example 3, different from the foregoing examples 1, 2 is that this example can explicitly indicate the corresponding feature information to the network device through the first information.

[0365] Specifically:

[0366] In one way, the first communication unit 61 of the terminal carries at least one feature information of the terminal in the first information.

[0367] And / or, in another way, the first communication unit 61 of the terminal carries the identification of the feature information group in the first information; wherein the identification of the feature information group is used to indicate at least one feature information contained in the feature information group. Correspondingly, the network device receives the identification of the feature information group carried by the terminal in the first information.

[0368] That is, the first information can only contain an identifier by which the corresponding feature information group can be reported; correspondingly, the second processing unit 72 of the network device can determine the feature information group reported by the terminal according to the identifier carried in the first information, and further determine the at least one feature information contained.

[0369] The first information is one of the following:

[0370] The PUSCH of the MSG3 of the four-step random access, the PUSCH of the MSG A in the two-step random access, RRC signaling, and MAC CE signaling.

[0371] As can be seen, by adopting the above scheme, the terminal can report the corresponding feature information to the network device. In this way, the network device can obtain the corresponding feature information of the terminal, and then facilitate the network device to make corresponding configuration or operation for the terminal based on the feature information of the terminal, so as to ensure that the terminal performs operations in line with its own characteristics in the network, and makes the terminal work normally in the communication system.

[0372] Finally, the embodiment also provides a way for different types of terminals, such as NR-Light terminals, to indicate corresponding related information through Preamble, wherein the related information can be information other than the aforementioned feature information. For example, the related information can be the capability, type, or capability level, category, etc. of the terminal, which is only used as an example for illustration and is not limited to the related information. In fact, there can be other related information, which is not exhaustively listed in this embodiment.

[0373] That is, the Preamble (preamble) can also be used to implicitly indicate other related information of the terminal.

[0374] Specifically as follows:

[0375] The first communication unit of the terminal, in the process of initiating random access, indicates that the feature information of the terminal is at least one corresponding related information by sending a second preamble Preamble / or a second Preamble group to the network device.

[0376] The second Preamble / or the second Preamble group is one of at least one Preamble or Preamble group; the related information corresponding to different Preamble groups in the at least one Preamble group is at least partially different, or the related information corresponding to different Preambles is at least partially different.

[0377] Correspondingly, in the process of random access, the second communication unit of the network device receives the second Preamble or the second Preamble group sent by the terminal; and determines at least one relevant information corresponding to the terminal according to the second Preamble or the second Preamble group.

[0378] The terminal determines that different Preamble groups in the at least one Preamble group correspond to different relevant information, or determines that different Preambles correspond to different relevant information, according to the fifth configuration information.

[0379] The fifth configuration information is preset or sent by the network device to the terminal.

[0380] The fifth configuration information can specifically include: at least one Preamble group, each Preamble group corresponding to relevant information; or at least one Preamble, each Preamble corresponding to relevant information.

[0381] The sending mode of the second Preamble group or the second Preamble can be:

[0382] The first communication unit carries the second Preamble group or the second Preamble by using a shared random access occasion (RO), or carries the second Preamble group or the second Preamble by using an independent RO.

[0383] Correspondingly, the second communication unit of the network device receives the second Preamble group or the second Preamble carried by using a shared random access occasion (RO), or receives the second Preamble group or the second Preamble carried by using an independent RO.

[0384] In the case of carrying the second Preamble group or the second Preamble by using a shared RO,

[0385] The first communication unit of the terminal receives sixth configuration information.

[0386] The sixth configuration information contains at least one Preamble group or Preamble used to indicate relevant information.

[0387] Correspondingly, the second communication unit of the network device sends the sixth configuration information to the terminal.

[0388] Here, the sixth configuration information can be carried by RRC signaling, MAC CE, or system broadcast information.

[0389] In addition, based on the foregoing, the sixth configuration information also includes: a set of at least one Preamble for two-step random access configured by the network device for the terminal.

[0390] The first communication unit of the terminal receives seventh configuration information; wherein the seventh configuration information includes at least one RO capable of carrying the second preamble group / or the second preamble.
