Description

Information reporting method, information acquisition method, terminal and network equipment

Technical Field

The present invention relates to the field of information processing technologies, and in particular, to an information reporting method, an information acquiring method, a terminal, a network device, a chip, a computer-readable storage medium, a computer program product, and a computer program.

Background

Under the continuous evolution and assistance Of wireless communication technology, the technology Of Internet Of Things (IOT, Internet Of Things) is rapidly developing. As the development of MTC (Machine-Type Communication)/eMTC (enhanced Machine-Type Communication) promoted by the 3GPP organization, the narrowband Band Internet of Things (NB-IoT) series standard becomes a candidate technical standard for 5G massive MTC (5G large MTC) technology. The technologies also have the limitation of some application scenarios, and since the MTC/eMTC, NB-IoT design goal is to support some applications with low data rate and high transmission delay, the technologies cannot be applied in some scenarios of internet of things that require relatively high rate, such as video monitoring in smart security and industrial applications that require relatively low delay. Therefore, in order to perfect a terminal system of a 5G massive MTC scenario, it is necessary to design an NR (New Radio) MTC terminal type that supports medium transmission rate and medium delay requirement and has lower cost, and 3GPP refers to the NR MTC terminal as an NR-light terminal. However, how to let the network know the characteristics of the terminal so that the network can be configured adaptively is a problem to be solved.

and receiving the characteristic information carried in the first information.

In this embodiment, the terminal may be an NR-terminal, or may be an NR-light terminal, and certainly, may also be other types of terminals in the IOT, which is not exhaustive here. The scheme provided by this embodiment may be directed to all types of terminals capable of accessing the communication network, that is, all types of terminals may send corresponding feature information to the network device.

First, the feature information described in this embodiment will be described:

the characteristic information comprises at least one of the following:

the number of antennas or antenna ports of the terminal;

a transmission bandwidth supported by the terminal;

the subcarrier spacing supported by the terminal;

the number of BWPs supported by the terminal;

BWP handover latency supported by the terminal;

the maximum number of HARQ processes supported by the terminal;

a maximum Transport Block (TB) size supported by the terminal;

relevant parameters monitored by the PDCCH supported by the terminal;

a parameter related to a processing capability of the terminal;

a parameter associated with a channel estimation capability of the terminal.

It should be noted that different terminals may include different feature information, and the terminal determines the specific content of the feature information to be reported according to its own condition, and in addition, the feature information included in the different terminals is one or more of the above-mentioned all feature information.

Still further, specific contents that each of the aforementioned feature information can include may be specifically referred to the following description:

the number of antennas or antenna ports of the terminal may include at least one of:

the number of antennas or antenna ports of the terminal;

the number of uplink transmitting antennas or antenna ports of the terminal;

the number of downlink receiving antennas or antenna ports of the terminal;

for example, the number of antennas or antenna ports provided for different NR-light terminals may be 1, 2, 4.

The number of the uplink transmitting antennas or the number of the antenna ports may be the same as or different from the number of the downlink receiving antennas or the number of the antenna ports.

In the solution provided in this embodiment, if the number of the uplink antennas and the number of the downlink antennas or the number of the antenna ports are the same, the number of the antennas or the number of the antenna ports may only be reported, that is, the number of the uplink antennas and the number of the downlink antennas or the number of the antenna ports of the terminal may be the same by default at the network side.

If not, the terminal may report the number of uplink antennas or antenna ports and the number of downlink receiving antennas or antenna ports, respectively.

For example, the number of uplink transmit antennas or antenna ports supported by a terminal for some special emergency scenarios may be different from the number of downlink receive antennas or antenna ports, for example, the terminal is mainly used for supporting uplink services, such as video monitoring, and the rate requirement of uplink data transmission is much greater than the requirement of downlink data downloading, so that a larger number of uplink antennas can be supported, and a smaller number of downlink receive antennas, such as uplink 4 antennas and downlink 2 receive antennas, can be supported.

The transmission bandwidth supported by the terminal may include at least one of:

transmission bandwidth supported by the terminal;

an uplink transmission bandwidth supported by the terminal;

downlink transmission bandwidth supported by the terminal.

That is, the terminal may report the transmission bandwidth supported by the terminal, and at this time, the network device may consider that the uplink and downlink transmission bandwidths of the terminal are the same.

In addition, if the uplink transmission bandwidth and the downlink transmission bandwidth of the terminal are different, the characteristic information of the terminal may include the uplink transmission bandwidth and the downlink transmission bandwidth supported by the terminal, respectively.

Still alternatively, at least one of a transmission bandwidth/uplink transmission bandwidth/downlink transmission bandwidth supportable by the terminal for a specific subcarrier spacing.

NR-light can support narrower transmission bandwidths such as 5MHz,10MHz or 20 MHz.

Similarly, some terminals may support different uplink and downlink bandwidths, and then the uplink bandwidth and the downlink bandwidth supported by the terminals may be reported by the terminals, for example, 10MHz for downlink and 20MHz for uplink.

The subcarrier spacing supportable by the terminal may be: the subcarrier spacing that the terminal can support, here, channels may not be distinguished, and is in units of terminals. Or, alternatively, may be a subcarrier spacing of a synchronization channel and/or a data channel that may be supported by the terminal. That is, the subcarrier interval corresponding to the synchronization channel may be the same as or different from the subcarrier interval of the data channel, and if the subcarrier intervals are the same, only the subcarrier intervals that the reporting terminal can support may be reported without distinction; if the two are different, the subcarrier intervals of the synchronization channel and the data channel supported by the terminal may be reported, or only one of the subcarrier intervals may be reported, which is not exhaustive here.

The number of BandWidth parts (BWP, BandWidth Part) supportable by the terminal may include at least one of:

the number of BWPs with different bandwidths that the terminal can support; if only one bandwidth is supported, only reporting the number of bandwidths and/or BWPs that can be supported by the terminal; if multiple bandwidths are supported, the multiple bandwidths and/or the number of BWPs supported by the terminal for each bandwidth may be reported separately.

A number of BWPs with different subcarrier spacings that the terminal can support; wherein, if there is only one subcarrier spacing, the terminal may report the number of supported subcarrier spacings and/or BWPs. If multiple subcarrier spacings are supported, each subcarrier spacing and/or its corresponding BWP number that can be supported by the terminal can be reported separately.

The number of UL (UpLink) BWPs that the terminal can support; that is, if the number of UL and DL BWPs supported by the terminal is different, the terminal may report only the number of UL BWPs supported by the terminal.

The number of UL BWPs with different bandwidths that the terminal can support; it is to be understood that the terminal may support UL BWPs with multiple bandwidths, or support UL BWPs with multiple bandwidths and the number of UL BWPs with different bandwidths, or may be only the number of UL BWPs corresponding to the UL BWPs with multiple bandwidths supported by the terminal.

A number of UL BWPs with different subcarrier spacings that the terminal can support; it can be understood that the terminal may support multiple subcarrier spacings, and then the number of different subcarrier spacings supported by the terminal and/or UL BWPs corresponding to different subcarrier spacings are reported separately.

A bandwidth size and/or subcarrier spacing of BWP supportable by the terminal; the terminal can report the subcarrier interval supported by the terminal to the network equipment, if the terminal supports one subcarrier interval, the terminal reports the subcarrier interval alone, and if the terminal supports a plurality of subcarrier intervals, the terminal needs to report the plurality of subcarrier intervals. In addition, if the BWP bandwidths supported by each subcarrier interval are the same in size, only one BWP bandwidth may be reported, and if the BWP bandwidths corresponding to different subcarrier intervals are different in size, multiple types of subcarrier intervals supported by the terminal and the BWP bandwidth size corresponding to each subcarrier interval need to be reported. Still further, if there are at least some subcarrier intervals corresponding to multiple BWP bandwidth sizes in the plurality of subcarrier intervals supported by the terminal, the number of BWP bandwidths corresponding to each subcarrier interval and the corresponding size thereof may be further included.

The number of DL (DownLink) BWPs that the terminal can support; that is, if the number of UL and DL BWPs supported by the terminal is different, the terminal may report only the number of DL BWPs supported by the terminal.

The number of DL BWPs with different bandwidths that the terminal can support; it can be understood that the terminal may support multiple bandwidths, and then report BWP bandwidths of different DLs and/or the number of DL BWPs of different bandwidths, respectively.

A number of DL BWPs with different subcarrier spacings that the terminal can support; it can be understood that the terminal may support multiple types of subcarrier spacings, and then the number of DL BWPs corresponding to different downlink subcarrier spacings and/or different subcarrier spacings supported by the terminal is reported respectively.

The larger the number of BWPs (or BWP configurations) supported by the terminal or the larger the number of BWP bandwidths supported by the terminal, the more complex the terminal design, e.g. for BWPs with different bandwidths, radio frequency and/or baseband filters with different bandwidth sizes need to be supported. Therefore, for terminals of some simple application scenarios, a limited number of BWPs or a limited BWP bandwidth size may be supported.

It should be understood that the specific content of the number of BWPs supported by the terminal may include one or more of the foregoing, and different terminals may report according to their actual situations. For example, the terminal may report that the number of UL BWPs that the terminal can support is 2, and at this time, if the number of DL BWPs is not reported, it may be defaulted that the UL and DL BWPs are the same and are also 2. Or, the feature information of the terminal may include that the number of UL BWPs that the terminal can support is 2, and the number of DL BWPs is 4. And are not exhaustive herein.

The delay of BWP handover supportable by the terminal may include:

time delay of BWP switching which can be supported by the terminal;

and/or, delay of UL BWP handover that the terminal can support;

and/or a delay of DL BWP handover that the terminal can support.

BWP handover may involve adjustment of radio frequency parameters of the terminal, such as bandwidth size, frequency location, or baseband parameters of the terminal, such as configuration of different PDCCH search spaces, and different applicable NR-light terminals may support different BWP handover delays. Some scenarios insensitive to the delay can support a larger BWP handover delay, which is used to relax the design requirement of the UE, thereby reducing the device cost of the terminal.

Similarly, if the delay of UL BWP handover that the terminal can support is the same as the delay of DL BWP handover, only the delay of BWP handover that the terminal can support may be reported; still alternatively, only the delay of UL or DL BWP handover may be reported. If the delay of UL BWP handover supportable by the terminal is different from the delay of DL BWP handover, the characteristic information may include both the delay of UL BWP handover and the delay of DL BWP handover.

The number of maximum HARQ (Hybrid Automatic Repeat reQuest) processes that can be supported by the terminal may be at least one of:

the maximum number of HARQ processes supportable by the terminal;

the maximum number of UL HARQ processes supportable by the terminal;

the maximum number of DL HARQ processes that the terminal can support.

It should be noted that the number of HARQ processes may affect a peak rate and a transmission delay of data transmission of the terminal, and the larger the number of HARQ processes, the higher the peak rate is, the lower the transmission delay is, but the larger the number of HARQ processes, the larger the chip area of the terminal may be, thereby increasing the cost of the terminal.

For the scenes that the data transmission delay is insensitive or the data rate requirement is low, the number of HARQ processes can be less, so that the cost of the terminal is reduced.

Similarly, if the maximum number of UL HARQ processes that can be supported by the terminal is the same as the maximum number of DL HARQ processes, only the maximum number of UL HARQ processes that can be supported by the terminal may be reported; still alternatively, only the maximum number of HARQ processes may be reported. If the maximum number of UL HARQ processes supportable by the terminal is different from the maximum number of DL HARQ processes, both the maximum number of UL HARQ processes and the maximum number of DL HARQ processes may be included in the characteristic information.

The maximum TB (Transport Block) size (size) supportable by the terminal may include at least one of:

maximum TB size supportable by the terminal;

maximum UL TB size supportable by the terminal;

maximum DL TB size supportable by the terminal.

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 may be reported; still alternatively, only the maximum TB size may be reported.

If the maximum UL TB size supportable by the terminal is different from the maximum DL TB size, both the maximum UL TB size and the maximum DL TB size may be included in the characteristic information.

The PDCCH (Physical Downlink Control CHannel) that the terminal can support monitors relevant parameters, which are at least one of the following:

the number of PDCCH blind tests in unit time; the unit time may be a time length set according to an actual situation, for example, may be 1ms or 1 timeslot, and may also be longer or shorter, which is not exhaustive here.

A minimum interval of supported adjacent PDCCH monitoring times;

the type of PDCCH aggregation levels supported; for example, the aggregation level of the PDCCH may be 1, 2, 4, or 8 CCEs, and the terminal selects one of the CCEs that can be supported by itself according to its own condition.

The number of PDCCH candidate locations supporting each aggregation level;

number of PDCCH CORESET (control resource set) configurations supported;

number of PDCCH search space sets supported.

For example, some terminals may support 44 PDCCH blind detection attempts within one ms, but some terminals may support only 22 PDCCH blind detection attempts, thereby reducing processor requirements and cost for the terminals.

A parameter related to a processing capability of the terminal, such as a capability related to a processing control channel or a data channel of the terminal; such as a timing difference between a PDCCH and a PDSCH (Physical Downlink shared CHannel)/PUSCH (Physical Uplink shared CHannel); or the timing difference between PDSCH and PUSCH. For example, some terminals may support longer timing differences of the aforementioned kind, thereby reducing the processor requirements and cost of the terminal. Of course, other types of the processing capability related parameters of the terminal may also exist, which are not exhaustive, and all the processing capability related parameters that can be used for indicating the terminal in the related art may be included in the embodiment of the present application.

A parameter associated with a channel estimation capability of the terminal. For example, the number of CCEs that the terminal does not overlap within one time unit (e.g., within 1ms, or within 1 slot).

In combination with the foregoing, the feature information reported by different terminals may be different or the same, and are determined according to their own conditions, for example, the feature information to be reported by terminal a may include: the number of supported uplink transmitting antennas is 2, and the number of supported downlink receiving antennas is 4; the supported transmission bandwidth is 5 MHz; the number of BWPs supported is 2, and so on. The feature information to be reported by the terminal B may include: the number of antennas supported is 4; the supported uplink transmission bandwidth is 5MHz, and the supported downlink transmission bandwidth is 10 MHz; the types of PDCCH aggregation types supported are 2, and so on. This embodiment is not exhaustive.

It should be noted that the terminal characteristics reported above are merely examples, and the specific types and numbers of the characteristics are not limited.

Based on the foregoing description of the feature information, the following describes a specific process of how the terminal indicates its feature information to the network device, with reference to various examples:

example 1, the characteristic information corresponding to the network device is implicitly indicated through a resource group of the PRACH. I.e. PRACH resource grouping may be employed to indicate different terminal feature groupings. The network may configure multiple sets of PRACH resources, each set of resource grouping corresponding to a set of terminal characteristics.

The method comprises the following specific steps:

the terminal indicates the characteristic information to be a first characteristic information group corresponding to a first resource group by transmitting a random access channel (PRACH) on the first resource group corresponding to the PRACH;

wherein, the first characteristic information group comprises at least one characteristic information;

the first resource group corresponding to the PRACH is one of at least one resource group corresponding to the PRACH; different resource groups in at least one resource group corresponding to the PRACH correspond to different characteristic information groups; each characteristic information group comprises at least one piece of characteristic information, and the characteristic information contained in different characteristic information groups is at least partially different.

Correspondingly, the network equipment receives the PRACH transmitted by the terminal on a first resource group corresponding to the PRACH; and the network equipment determines the characteristic information as a corresponding first characteristic information group according to the first resource group corresponding to the PRACH.

Each set of characteristic information contains one or more of the aforementioned characteristic information. All of the aforementioned characteristic information may be used, or some of the characteristic information may be used.

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

the first configuration information is preset or sent to the terminal by the network device.

Wherein, the network device sends the system information to the terminal, such as SIB, MIB, etc. to configure the terminal; or, sending the data to the terminal through the MAC CE; or, the configuration may be performed to the terminal through RRC signaling, which is not exhaustive here.

It should be understood that the first configuration information is also stored at the network device side, and may be preset at the network device side according to a protocol, or may be generated by the network device according to the protocol, and if the first configuration information is generated by the network device, the network device needs to send the first configuration information to the terminal.

The first configuration information may specifically include: at least one PRACH resource group, and a characteristic information group corresponding to the resource group corresponding to each PRACH.

For example, the definition of a particular characteristic for each of a plurality of sets of terminal characteristics may be predefined or pre-configured by the network. If three groups of terminal characteristic information are predefined:

the characteristic information group 1 supports 2 receiving antennas and supports a terminal bandwidth of 5 MHz; 2 BWP configuration is supported; 4 HARQ process numbers are supported.

The characteristic information group 2 supports 4 receiving antennas and supports 20MHz terminal bandwidth; 4 BWP configurations are supported; 8 HARQ process numbers are supported.

The characteristic information group 3 supports 4 receiving antennas, and supports a downlink receiving bandwidth of 10MHz and an uplink transmitting bandwidth of 20 MHz; 2 BWP configuration is supported; 4 HARQ process numbers are supported.

Then in the first configuration information, resource group 1 corresponds to feature information group 1, resource group 2 corresponds to feature information group 2, and resource group 3 corresponds to feature information group 3.

The aforementioned first resource group may be one of one or more resource groups, and is referred to as the first resource group.

If the first configuration information only contains one resource group and the corresponding characteristic information group, the resource group indicated in the first configuration information is directly used as the first resource group without selection.

If two or more resource groups are included in the first configuration information, the processing of the terminal may further include:

selecting a first resource group matched with the characteristic information to be sent from the plurality of resource groups according to the characteristic information of the first resource group; then, transmitting PRACH in the first resource group;

correspondingly, the network device receives the PRACH sent by the terminal on the resource corresponding to the first resource group, and then the network device may determine the first characteristic information group of the terminal according to the first resource group; and then, the network equipment determines at least one piece of characteristic information reported by the terminal according to the first characteristic information group.

More specifically, if the plurality of resource groups may not include all feature information to be reported by the terminal, a first resource group at least partially matching with all feature information to be reported by the terminal is selected from the plurality of resource groups.

Further, with reference to the foregoing example, if the feature information to be reported by the terminal is the feature information group 2, the resource group 2 corresponding to the feature information group 2 may be used as the first resource group; and then the terminal transmits the PRACH in the first resource group. If the network device receives the PRACH in the first resource group, it may be determined that the terminal has reported the feature information group 2, and then the feature information of the terminal is determined based on the content of the feature information group 2.

Example 2, the corresponding feature information of the network device is implicitly indicated by a Preamble. That is, preamble packets may be employed to indicate different terminal feature packets. The network may be configured with multiple sets of preambles, each set of preamble grouping corresponding to a set of terminal characteristics.

The method comprises the following specific steps:

in the process that the terminal initiates random access, the terminal indicates that the characteristic information of the terminal is a second characteristic information group corresponding to a first Preamble by sending the first Preamble group to the network equipment;

wherein the second characteristic information group includes at least one of the characteristic information.

Wherein, 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 comprises at least one piece of characteristic information, and the characteristic information contained in different characteristic information groups is at least partially different.

Correspondingly, in the process of random access, the network equipment receives a first Preamble group sent by the terminal; and the network equipment determines a second characteristic information group corresponding to the terminal according to the first Preamble.

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;

the second configuration information is preset, or is sent to the terminal by a network device.

Wherein, the network device sends the system information to the terminal, such as SIB, MIB, etc. configured to the terminal; or, sending the data to the terminal through the MAC CE; or, the configuration may be performed to the terminal through RRC signaling, which is not exhaustive here.

It should be understood that the second configuration information is also stored at the network device side, and may be preset at the network device side according to a protocol, or may be generated by the network device according to the protocol, and if the second configuration information is generated by the network device, the network device needs to send the second configuration information to the terminal.

The second configuration information may specifically include: at least one Preamble group, and each Preamble group corresponds to a characteristic information group.

The definition of a specific feature for each of the sets of terminal characteristics may be predefined or pre-configured by the network. If three sets of terminal characteristics are predefined:

the first group of terminals are characterized by supporting 1 receiving antenna and 5MHz terminal bandwidth; 2 BWP configuration is supported; 4 HARQ process numbers are supported.

The second group of terminals is characterized by supporting 2 receiving antennas and 20MHz terminal bandwidth; 4 BWP configurations are supported; 8 HARQ process numbers are supported.

The third group of terminals are characterized by supporting 2 receiving antennas, and supporting a downlink receiving bandwidth of 10MHz and an uplink transmitting bandwidth of 20 MHz; 2 BWP configuration is supported; 4 HARQ process numbers are supported.

For example, the following may be determined by the content of the second configuration information:

the available preamble set of the terminal is [ 035 ], then three sets of preamble subsets can be adopted to respectively correspond to the three sets of terminal features, for example, the preamble set is [ 011 ] corresponding to the first set of terminal features, the preamble set is [ 1223 ] corresponding to the second set of terminal features, and the preamble set is [ 2435 ] corresponding to the third set of terminal features.

Furthermore, the first Preamble group may be one of one or more Preamble groups, and is referred to as the first Preamble group.

If the second configuration information only contains one Preamble group and the corresponding characteristic information group, the selection is not needed, and the Preamble group indicated in the second configuration information is directly used as the first Preamble group.

If the second configuration information includes two or more Preamble groups, the processing of the terminal may further include:

selecting a first Preamble group matched with the characteristic information to be sent from the plurality of Preamble groups according to the characteristic information of the first Preamble group; then, transmitting a Preamble group; correspondingly, the network device receives the first Preamble group sent by the terminal, and then the network device can determine the second characteristic information group of the terminal according to the first Preamble group; and then, the network device can determine at least one piece of feature information reported by the terminal according to the second feature information group.

Specifically, all the characteristic information to be reported by the terminal may not be included in the plurality of Preamble groups, and then a first Preamble group at least partially matching with all the characteristic information to be reported by the terminal is selected from the plurality of Preamble groups.

That is, when initiating access at any time, the terminal selects a Preamble from the Preamble set (or Preamble group) corresponding to the set of terminal features. And combining the preamble packet and the terminal characteristics corresponding to the preamble packet, the network can judge the terminal characteristics initiating the random access when receiving the preamble, and further perform reasonable resource allocation on the subsequent data transmission of the terminal.

In this example, the manner of sending the first Preamble group may be:

and adopting a shared random access time (RO) to bear the first lead code Preamble group, or adopting an independent RO to bear the first lead code Preamble group.

It is to be understood that the preamble is carried (or transmitted) in the RO, and there may be 64 preambles on one RO.

Correspondingly, the manner of receiving the first Preamble group by the network device is as follows: receiving the first Preamble group carried by RO at a shared random access time, or receiving the first Preamble group carried by independent RO.

That is, the preamble for indicating the terminal characteristic may be in a manner of sharing a random access timing (RO) with a normal NR terminal, or in a manner of separately configuring an independent RO.

If the independent RO is configured separately, the transmission may be performed according to the independently configured RO, which is not described in detail herein.

The present example is mainly described with respect to the manner of sharing RO:

in case of using a shared RO bearer for the first Preamble group,

the method further comprises the following steps:

the terminal receives third configuration information;

wherein the third configuration information includes: the network equipment configures a set consisting of at least one Preamble for competing random access CBRA for the terminal; and at least one Preamble set for indicating the characteristic information of the terminal.

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

Here, the third configuration information may be carried by RRC signaling, MAC CE, or system broadcast information.

The set of at least one Preamble for contention for random access CBRA may be understood as a set of preambles occupied by four-step random access,

for example, referring to fig. 4, for the RO sharing manner, the Preamble set of the reported terminal feature may be configured outside the Preamble set occupied by the normal NR terminal for configuring CBRA (Contention Based Random Access) (that is, configured outside the Preamble set occupied by four-step Random Access), may be configured near the Preamble set occupied by the normal NR terminal for CBRA (Contention Based Random Access), and may be configured after the Preamble set occupied by the normal NR terminal for reporting the terminal feature.

In addition, in addition to the above, the third configuration information further includes: the network equipment configures a set consisting of at least one Preamble for two-step random access for the terminal.

For example, referring to fig. 5, if the system is further configured with a 2-step RACH and the Preamble allocated to the 2-step RACH shares an RO with the normal NR terminal, the Preamble set reporting the terminal characteristics may be configured outside a Preamble set occupied by configuring the normal NR terminal for CBRA (that is, a set composed of at least one Preamble used for four-step random access) and a set composed of at least one Preamble used for two-step random access, for example, at least one Preamble group for indicating the characteristic information of the terminal may be configured after the Preamble set allocated to the 2-step RACH is configured.

Further, the RO shared by the preamble indicating the terminal characteristic with the normal NR terminal may be a part of all ROs used by the normal NR terminal. The method then further comprises:

the terminal receives fourth configuration information; wherein the fourth configuration information includes: can be used to carry at least one RO of the first Preamble group.

Correspondingly, the network equipment sends fourth configuration information to the terminal; wherein the fourth configuration information includes: can be used to carry at least one RO of the first Preamble group.

That is, the network device may send fourth configuration signaling indicating which ROs, among all ROs used by a normal NR terminal, are also used to carry a preamble indicating a terminal characteristic.

It should be noted that the fourth configuration information and the third configuration information may be carried in the same signaling, for example, may be contained in two IEs in the same signaling, and of course, the fourth configuration information and the third configuration information may also be sent in two signaling separately, which is not limited herein.

Example 3, unlike the foregoing examples 1, 2, this example may be explicit indication of corresponding feature information to the network device by the first information.

Specifically, the method comprises the following steps:

in one mode, the terminal carries at least one piece of feature information of the terminal in the first information.

That is to say, in an enumerated manner, the first information carries all feature information to be reported by the terminal, and for example, the feature information may include: the number of supported uplink transmitting antennas is 2, and the number of supported downlink receiving antennas is 4; the supported transmission bandwidth is 5 MHz; the number of BWPs supported is 2, and so on. Correspondingly, the network device directly obtains the characteristic information reported by the terminal through the received first information.

And/or, in another way, the terminal carries the identifier of the characteristic information group in the first information; wherein the identifier of the characteristic information group is used for indicating at least one characteristic information contained in the characteristic information group. Correspondingly, the network device receives the identifier of the characteristic information group carried by the terminal in the first information.

That is, the first information may include only one identifier, and the corresponding feature information group may be reported through the identifier; correspondingly, the network device may determine the feature information group reported by the terminal according to the identifier carried in the first information, and further determine at least one feature information included in the feature information group.

The first information is one of the following information:

PUSCH of MSG3 in four-step random access, PUSCH of MSG A in two-step random access, RRC signaling, and MAC CE signaling.

Still further, in this manner, at least one piece of feature information corresponding to the identifier of the feature information group may be preconfigured for both the terminal and the network device.

That is, the terminal and the network device may group terminal characteristics in advance. And the terminal reports the group identification of the terminal characteristics.

Further, the two manners may be used singly or in combination, for example, if the feature information group does not include all feature information, the terminal may report part of the feature information through the identifier of the feature information group, and report the remaining feature information respectively.

For example, the number of feature information to be reported by the terminal is 10, where there are 6 feature information groups that can have a corresponding feature information, and then the first information carries the identifiers of the feature information groups corresponding to the 6 feature information; the remaining 4 pieces of feature information may be carried in the first information and reported.

For example, the identifier 1 of the feature information group may be carried in the first information, and various parameters of the terminal feature, such as the number of supported terminal antennas, the number of ports, the terminal bandwidth, the number of supported BWPs, and the like, may also be carried.

The foregoing examples 1, 2 and 3 may be used alone, and in some possible embodiments, the foregoing manners of reporting the terminal characteristics may also be used in combination. For example, a PRACH channel or a Preamble may be used to report part of the terminal characteristics, such as the number of antennas/ports supported; and reporting one or more characteristics including the supported bandwidth, the number of BWPs, the number of HARQ processes and the like through RRC signaling, that is, the first information.

For example, examples 1 and 3 may be used in combination, where the terminal uses, as the first feature information group, feature information of a feature information group, which is capable of corresponding to a PRACH resource group included in the first configuration information, in all feature information to be reported, and indicates, based on the first resource group of the PRACH corresponding to the first feature information group, the first feature information group corresponding to the network device, 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 may be referred to as second partial feature information) of the feature information to be reported, except for the first feature information group, one by one through the first information.

The method can also comprise the following steps: the terminal matches the second part of feature information with a preset feature information group identifier and at least one piece of feature information corresponding to the second part of feature information, and can report one part of the second part of feature information by the first information carrying the identifier of the feature information group corresponding to the first part of feature information; and finally, carrying the other part of feature information in the second part of feature information by the first information.

As another example, examples 2, 3 may be used in combination,

and the terminal takes the feature information of the feature information group corresponding to the Preamble group contained in the second configuration information in all the feature information to be reported as a feature information group A, and indicates the feature information group A corresponding to the network equipment based on the first Preamble group corresponding to the feature information group A, so that the network equipment determines the feature information group A and at least one piece of feature information corresponding to the feature information group A according to the first Preamble group. Then, the terminal reports the remaining feature information (which may be referred to as a third part of feature information) of the feature information to be reported except the feature information group a one by one through the first information.

The method can also comprise the following steps: the terminal matches the third part of feature information with a preset feature information group identifier and at least one piece of feature information corresponding to the preset feature information group identifier, and can report one part of the third part of feature information by the first information carrying the identifier of the feature information group corresponding to the first information; and finally, carrying the other part of feature information in the third part of feature information by the first information.

Or, examples 1, 2, and 3 may be further combined, for example, the terminal determines the feature information to be reported; then, determining a feature information group 1 contained in a feature information group corresponding to the PRACH resource group according to the first configuration information, and determining a feature information group 2 contained in feature information corresponding to the Preamble group according to the second configuration information (the feature information groups 1 and 2 may overlap differently, but if all the feature information groups overlap, only one mode can be selected for reporting, and if part of the feature information groups are different, both the feature information groups can be adopted);

the terminal determines a corresponding PRACH resource group 1 based on the characteristic information group 1, and PRACH transmission is carried out through the PRACH resource group 1; correspondingly, after receiving the PRACH from the PRACH resource group 1, the network device determines that the corresponding feature information group is the feature information group 1, and then obtains the feature information corresponding to the terminal;

the terminal determines a corresponding Preamble group 2 based on the characteristic information group 2, and transmits the Preamble group 2 on the RO (in the random access process); correspondingly, after receiving the Preamble group 2, the network device determines that the Preamble group 2 corresponds to the characteristic information group 2, and then the network device obtains the characteristic information corresponding to the terminal.

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

Finally, the embodiment also provides a manner, for different types of terminals, such as an NR-Light terminal, corresponding related information may also be indicated by a Preamble, where the related information may be information other than the aforementioned characteristic information. For example, the related information may be a capability, a type, or a capability level, a category, etc. of the terminal, which is merely described as an example and is not limited to the related information.

That is, other related information of the terminal may also be implicitly indicated through a Preamble.

The method comprises the following specific steps:

in the process that the terminal initiates random access, the terminal indicates that the characteristic information of the terminal is at least one corresponding piece of relevant information by sending a second Preamble/or a second Preamble group to the network device.

Wherein, the second Preamble/or the second Preamble group is one of at least one Preamble or Preamble group; at least part of the related information corresponding to different Preamble groups in the at least one Preamble group is different, or at least part of the related information corresponding to different preambles is different.

Correspondingly, in the process of random access, the network device receives a second Preamble and/or a second Preamble group sent by the terminal; and the network equipment determines at least one piece of relevant information corresponding to the terminal according to the second Preamble/second Preamble group.

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, determining different relevant information corresponding to the at least one Preamble.

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

The fifth configuration information sent by the network device to the terminal may be configured to the terminal through system information, such as SIB, MIB, and the like; or, sending the data to the terminal through the MAC CE; or, the configuration may be performed to the terminal through RRC signaling, which is not exhaustive here.

It should be understood that the fifth configuration information is also stored at the network device side, and may be preset at the network device side according to a protocol, or may be generated by the network device according to the protocol, and if the fifth configuration information is generated by the network device, the network device needs to send the fifth configuration information to the terminal.

The fifth configuration information may specifically include: at least one Preamble group, and related information corresponding to each Preamble group; or, the related information corresponding to each Preamble in the at least one Preamble.

For example, the following may be determined by the content of the fifth configuration information:

the preamble set available to the terminal is [ 035 ], and three sets of preamble subsets may be adopted to respectively correspond to the three sets of related information, for example, the preamble set corresponds to the first set of related information [ 113 ], the preamble set corresponds to the second set of related information [ 1425 ], and the preamble set corresponds to the third set of related information [ 1831 ].

If the fifth configuration information only includes one Preamble group and the corresponding related information group, the selection is not required, and the Preamble group indicated in the fifth configuration information is directly used as the second Preamble group.

If the fifth configuration information includes two or more Preamble groups, the processing of the terminal may further include:

selecting a second Preamble group or a second Preamble matched with the relevant information to be sent from the plurality of Preamble groups or the plurality of preambles according to the relevant information to be sent; then, transmitting a second Preamble group or a second Preamble;

correspondingly, the network device receives the second Preamble group or the second Preamble sent by the terminal, and then the network device may determine, according to the fifth configuration information, the second group of related information of the terminal corresponding to the second Preamble group or the second Preamble; furthermore, the network device can determine at least one piece of relevant information reported by the terminal according to the second group of relevant information.

The manner of sending the second Preamble group or the second Preamble may be:

and adopting a shared random access time (RO) to bear the second Preamble group or the second Preamble, or adopting an independent RO to bear the second Preamble group or the second Preamble.

Correspondingly, the manner of receiving the second Preamble group or the second Preamble by the network device is as follows: receiving the second Preamble group or the second Preamble carried by the RO at the shared random access time, or receiving the second Preamble group or the second Preamble carried by the independent RO.

That is, the preamble for indicating the related information may be in a manner of sharing a random access timing (RO) with a normal NR terminal, or in a manner of separately configuring an independent RO.

in case of using a shared RO to carry the second Preamble group or the second Preamble,

the method further comprises the following steps:

the terminal receives sixth configuration information;

wherein the sixth configuration information includes: at least one Preamble group or Preamble for indicating related information.

It should be further understood that the sixth configuration information may further include at least part of the content included in the third configuration information in the foregoing example 2, for example, the sixth configuration information may further include:

the network equipment configures a set consisting of at least one Preamble for competing for random access CBRA for the terminal, and/or at least one Preamble group for indicating the characteristic information of the terminal. And will not be described in detail herein.

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

Here, the sixth configuration information may be carried by RRC signaling, MAC CE, or system broadcast information.

In addition, in addition to the above, the sixth configuration information further includes: the network equipment configures a set consisting of at least one Preamble for two-step random access for the terminal.

Further, the RO shared by the preamble indicating the relevant information of the terminal with the normal NR terminal may be a part of all ROs used by the normal NR terminal. The method then further comprises:

the terminal receives seventh configuration information; wherein the seventh configuration information includes: at least one RO capable of being used to carry the second Preamble group/or the second Preamble.

It should be noted that the seventh configuration information and the sixth configuration information may be carried in the same signaling, for example, may be contained in two IEs in the same signaling, and of course, the seventh configuration information and the sixth configuration information may also be sent in two signaling separately, which is not limited herein.

Therefore, by adopting the scheme, the terminal can report the corresponding characteristic information to the network equipment. Therefore, the network equipment can acquire the characteristic information corresponding to the terminal, and then the network equipment can conveniently perform corresponding configuration or corresponding operation on the terminal based on the characteristic information of the terminal, so that the terminal is ensured to execute the operation according with the characteristics of the terminal in the network, and the terminal can normally work in a communication system.

For example, some terminals may support longer timing differences of the aforementioned kind, thereby reducing the processor requirements and cost of the terminal.
