Description

Processing method of random access process, terminal equipment and network equipment

Technical Field

The present invention relates to the field of communications, and in particular, to a method for processing a random access procedure, a terminal device, and a network device.

Background

In a New Radio (NR) system, a terminal equipment (UE) generally has three states, namely an Idle (Idle) state, a Connected state (which may also be referred to as Radio Resource Control (RRC) Connected state (RRC-Connected)), and an Inactive (RRC _ Inactive) state.

The UE in Idle state has no RRC context on the network side, i.e. the parameters necessary for communication between the network side and the UE do not belong to a specific cell, and the network side does not know whether the UE exists. The UE is assigned a set of Tracking Area Identifier (TAI) list (list). From the core network perspective, the Radio Access Network (RAN) side has disconnected from the core network. In order to reduce power consumption, the UE is in a sleep state for most of the time, and thus cannot perform data transmission. In the downlink, the UE in Idle state may periodically wake up to receive paging messages from the network. Mobility (Mobility) may be handled by the UE for cell reselection. In the Idle state, the UE and the network side do not keep uplink synchronization, and if the Idle state is to be switched to the Connected state, the UE and the network side can only establish an RRC context through Random Access (Random Access).

In the RRC _ Connected state, an RRC context may be established and all parameters needed for communication are known to both entities (UE and network side). From the core network perspective, the UE is in the CN _ Connected state. The cell to which the UE belongs is known and has been configured with a device identity, i.e. a cell radio network temporary identifier (C-RNTI), for the purpose of transmitting signalling between the device and the network. Data can be transmitted in a connected state, but since the data stream of a packet is usually bursty, when no data stream is transmitted, the power consumption can be reduced by turning off the receiving circuit of the UE, and a DRX (Discontinuous Reception) technology is adopted. Leaving DRX and starting to receive/transmit data is relatively fast, since the RRC context is already established in the gNB in the connected state. In the connected state, Mobility may be controlled by the network side, i.e. the UE provides neighbor cell measurements to the network, and the network commands the device to perform handover (handover). The uplink time synchronization may or may not exist, and when there is data to be transmitted, the uplink synchronization may be established by using random access.

In the RRC _ INACTIVE state, the RRC context of the network side and the UE side is maintained. From the core network perspective, the RAN side is in a state of connection with the core network. The transition from the inactive state to the connected state is fast and does not require core network signaling. Meanwhile, the UE is allowed to sleep in an idle state-like manner, and thus data transmission is not possible. And, the UE handles mobility through cell reselection. Thus, RRC _ INACTIVE may be considered a mix of idle and connected states.

Therefore, in the related art, when the UE is in the non-connected state, the UE and the network side cannot perform data transmission, and therefore, the UE in the non-connected state cannot report large uplink information to the network side, for example, measurement information obtained by measuring the UE in the idle state.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1 is a flowchart illustrating a method for processing a random access procedure according to an embodiment of the present invention, where the method 100 may be executed by a terminal device. In other words, the method may be performed by software or hardware installed on the terminal device. As shown in fig. 1, the method may include the following steps.

S110, in a non-connection state, in a random access process, sending a target random access preamble sequence, and instructing a network side to allocate uplink resources not less than a first preset value to the terminal device, wherein the uplink resources are used for reporting uplink information in the random access process.

In embodiments of the present invention, the disconnected state includes, but is not limited to: an idle (idle) state and an inactive (inactive) state.

In one possible implementation, the uplink information may be location information. That is, in the optional implementation manner, when the UE is in the non-connected state, if the UE needs to report the location information, the UE may initiate a random access process, and request the network side to allocate an uplink resource larger than the first preset value to the UE, so that the UE may report the location information in the random access process.

In a possible implementation manner, in S110, the UE may send a target random access preamble sequence (preamble) in a random access process, and instruct the network side to allocate uplink resources for a predetermined message of the UE in the random access process. In this possible implementation manner, the UE reports the location information through a predetermined message in the random access process, where the predetermined message may be a message sent by the UE to the network side in the existing random access process. For example, msg3 in a 4-step Random Access (RACH) procedure, or msg a in a 2-step RACH procedure.

Optionally, the instructing the network side to allocate, to the terminal device, uplink resources not smaller than a first preset value includes: in the 4-step RACH, allocating an uplink resource or UL grant larger than a first preset value to the UE in mag2 for instructing the network side, and optionally reporting the location information.

Optionally, the instructing the network side to allocate, to the terminal device, uplink resources not smaller than a first preset value includes: in the 2-step RACH, a specific PO resource is indicated to be received by a network side, wherein the PO resource is an RO resource associated with the sending target sequence; further, the PO resource is not less than the uplink resource of the first preset value (the PO resource is not less than the uplink resource which can be realized by a coding mode, time frequency resource allocation and the like)

In the possible implementation manner, the target preamble may be one of the configured specific preambles, and the specific preamble indicates that the network side UE will report the location information in the random access process, so that the network side allocates the corresponding uplink resource. Alternatively, a specific preamble is used in combination with an indication of the location information included in the upload data (e.g., enabling the indication of the location information in the upload data) to indicate that the UE is to report the location information in the random access procedure.

In one possible implementation, the specific preamble may be a reserved or pre-configured preamble dedicated to indicate that location information is to be reported. The reservation or pre-configuration may be a permanent reservation specified by a protocol for location service, or may be configured in advance by a network side. For example, assuming that 16 preambles are configured in the system, which are preamble 0, preamble1, …, and preamble15, respectively, then preamble14 and preamble15 may be reserved or preconfigured as preambles dedicated to location services, and the UE sends preamble14 or preamble15 to the network side to indicate that location information is to be reported.

In another possible implementation manner, the specific preamble may also be determined by specific configuration information, where the configuration information may be configuration information sent by the network side, for example, configuration information sent by the network side through msg0 of the random access procedure.

In the foregoing possible implementation manner, the network side may directly indicate an index of a specific preamble in the configuration information, or the network side may also indicate related information of the preamble configured by the network side in the configuration information, and the UE side determines the specific preamble according to the related information of the preamble configured by the network side.

In a possible implementation manner, the network side may group the preambles and configure the uplink resource threshold corresponding to each preamble group, and then the maximum uplink control resource size corresponding to each preamble in the preamble group indicates the uplink resource threshold corresponding to the preamble group through the configuration information (e.g., the parameter ra-Msg3 SizeGroup). In this possible implementation, the configured specific preamble satisfies one of:

(1) if the uplink resource threshold corresponding to the first random access preamble sequence Group (e.g., Group a) configured on the network side is not less than the first preset value, e.g., 1000bit, 1024bit, 2000bit, 2560bit, or 2048bit, the configured specific random access preamble sequence may be a part or all of the random access preamble sequences in the first random access preamble sequence Group, and the resource size or the indication location information may be indicated by further defining parameters and Group classification.

For example, if the network side is configured with Preamble Group a and the uplink resource threshold corresponding to the Preamble Group a is not less than the first preset value, it indicates that the uplink resource size corresponding to the Preamble in Group a can meet the requirement of the location information to be uploaded, and therefore, the configured specific random access Preamble sequence is the Preamble in Group a.

Optionally, if a reserved or preconfigured preamble is contained in Group a, the configured specific random access preamble sequence is the reserved or preconfigured preamble in Group a.

(2) If a second random access preamble sequence Group (e.g., Group B) is not configured, and the uplink resource threshold corresponding to the first random access preamble sequence Group is smaller than the first preset value, the configured specific random access preamble sequence includes: and the preset random access preamble sequence in the first random access preamble sequence group.

If the network side does not configure the Preamble Group B, but the uplink resource threshold corresponding to the Preamble Group a is smaller than the first preset value, it indicates that the uplink resource size corresponding to the Preamble in the Group a cannot meet the requirement of the location information to be uploaded, and therefore, in order to enable the network side to allocate a larger uplink resource, the configured specific random access Preamble sequence selected by the UE is the preset Preamble in the Group a. That is, when the network side configures the Group a, one or more preset preambles are configured in the Group a, and if the UE selects the preset Preamble, the UE is indicated to need an uplink resource larger than an uplink resource threshold corresponding to the Preamble Group pa or to have location information to report.

Optionally, if the network side or the protocol does not configure a specific preamble in the Group a, waiting for next configuration information, and entering into a connected state for reporting without initiating random access or reporting only the location indication information or reporting the location information by the random access this time.

(3) If a second random access preamble sequence group is configured, the uplink resource threshold corresponding to the first random access preamble sequence group is smaller than the first preset value, and the uplink resource threshold corresponding to the second random access preamble sequence group is not smaller than the first preset value, the configured specific random access preamble sequence includes: and the second random access preamble sequence group comprises preset random access preamble sequences.

For example, if the network side is configured with a Preamble Group B, and the uplink resource threshold corresponding to the Preamble Group B is not smaller than the first preset value, but the uplink resource threshold corresponding to the Preamble Group a is smaller than the first preset value, it indicates that the uplink resource size corresponding to the Preamble in the Group a cannot meet the requirement of the location information to be uploaded, and the uplink resource size corresponding to the Preamble in the Group B can meet the requirement of the location information to be uploaded, so that the configured specific random access Preamble sequence includes part or all of the preambles in the Group B.

In this possible implementation manner, a Preamble Group B is configured on the network side, and when the uplink resource threshold corresponding to the Preamble Group a is not smaller than the first preset value but the uplink resource threshold corresponding to the Preamble Group a is smaller than the first preset value, further, when the random access Preamble sequence Group power offset value (e.g., the parameter ra-messagepoweroffsetgroup pb in msg0) corresponding to the Preamble Group B is smaller than or greater than a certain preset value, the Preamble in the Group B may be selected as the specific Preamble.

Optionally, if a reserved or preconfigured preamble is contained in Group B, the configured specific random access preamble sequence is the reserved or preconfigured preamble in Group B.

Optionally, if the reserved or preconfigured preamble corresponds to resources of different levels according to a certain rule, selecting a suitable preamble for transmission

(4) If a second random access preamble sequence group is configured, the uplink resource threshold corresponding to the first random access preamble sequence group is smaller than the first preset value, and the uplink resource threshold corresponding to the second random access preamble sequence group is smaller than the first preset value, the configured specific random access preamble sequence includes: a preset random access preamble sequence in the second random access preamble sequence Group or a random access preamble sequence in a third random access preamble sequence Group (e.g., Group C).

For example, if the network side is configured with a Preamble Group B, but uplink resource thresholds corresponding to the Preamble Group a and the Preamble Group B are both smaller than the first preset value, it indicates that the uplink resource sizes corresponding to the preambles in the Group a and the Group B cannot meet the requirement of the location information to be uploaded, and therefore, in order to enable the network side to allocate a larger uplink resource, the configured specific random access Preamble sequence selected by the UE is the preset Preamble in the Group B. That is, when the network side configures the Group B, one or more preset preambles are configured in the Group B, and if the UE selects the preset Preamble, the UE is indicated to need an uplink resource larger than an uplink resource threshold corresponding to the Preamble Group B.

Or, the network side may also configure a new Preamble Group, that is, a Preamble Group C, and the size of the uplink resource corresponding to the Preamble in the Preamble Group C is greater than the size of the uplink resource corresponding to Group a and Group B, so that the configured specific random access Preamble sequence is the Preamble in Group C when both the uplink resource thresholds corresponding to the Preamble Group a and the Preamble Group B are less than the first preset value.

In the foregoing possible implementation manner, if the configured specific Preamble (including the reserved or preconfigured Preamble dedicated to indicate the location information to be reported and the specific Preamble configured according to the configuration information sent by the network side) is one, for example, only one index of the reserved or preconfigured Preamble dedicated to indicate the location information to be reported is provided, the type of the location information to be reported may be determined according to the specific Preamble.

For example, in a possible implementation manner, the type of the location information to be reported may be determined according to the random access preamble sequence group in which the specific preamble is located. For example, if the specific preamble indicates in preamble group a that absolute location information or relative location information or location change indication information is to be uploaded. As the particular preamble indicates in preamble group B that measurement information is to be uploaded. Conversely, the information indicated by the specific preamble located in group a or located in group B may also be interchanged. Optionally, when the specific preamble is reserved or preconfigured, the reserved or preconfigured specific preamble may be allocated in the corresponding random access preamble sequence group according to the type of the location information that needs to be uploaded by the UE.

In another possible implementation manner, the type of the location information to be reported may also be determined according to an uplink resource threshold (e.g., ra-Msg3SizeGroup) corresponding to the random access preamble sequence group in which the specific preamble is located, and/or a power offset value (e.g., ra-messagePowerOffsetGroup) of the random access preamble sequence group, that is, a related parameter of the random access preamble sequence group in the configuration information sent by the network side.

For example, if the specific preamble is located in the first random access preamble sequence Group, in the configuration information sent by the network side, the uplink resource threshold ra-MsgA-SizeGroupA corresponding to Group a is smaller than a first preset threshold, indicating that the uploaded location information is absolute location information or relative location information or location indication or request information. And if the uplink resource threshold ra-MsgA-SizeGroupA corresponding to the Group A is not less than a first preset threshold, indicating that the uploaded position information is measurement information. For example, when a specific preamble is reserved or preconfigured, an uplink resource threshold corresponding to a random access preamble sequence group in which the specific preamble is reserved or preconfigured may be configured according to a type of location information that needs to be uploaded by the UE.

If the specific preamble is located in the second random access preamble sequence Group, and a power offset value (ra-messagePowerOffsetGroupB) corresponding to Group B in the configuration information sent by the network side is smaller than a second preset threshold value, indicating that the position information to be uploaded is absolute position information or relative position information, and if the power offset value (ra-messagePowerOffsetGroupB) corresponding to Group B is not smaller than the second preset threshold value, indicating that the position information to be uploaded is measurement information.

Or, the type of the location information to be reported may be determined by combining two parameters, i.e., an uplink resource threshold (e.g., ra-Msg3SizeGroup) corresponding to the random access preamble sequence group in which the specific preamble is located and a power offset value (e.g., ra-messagePowerOffsetGroup) of the random access preamble sequence group.

In a possible implementation manner, if there are multiple configured specific preambles (including the above-mentioned reserved or preconfigured preambles dedicated to indicate that location information is to be reported, and the specific preambles configured according to the configuration information sent by the network side). For example, there are a plurality of indexes reserved or pre-configured for a preamble indicating location information to be reported. Then, according to the convention with the network side, configuration information corresponding to each specific random access preamble sequence may be determined, where the configuration information includes: the type of the reported position information or the size of the requested uplink resource. That is to say, different meanings may be specified for different configured specific preambles, for example, assuming that a reserved or preconfigured preamble dedicated to indicate that location information is to be reported includes preamble14 and preamble15, the preamble14 may be configured to indicate that absolute location information or relative location information is reported, and the preamble15 is configured to indicate that measurement information is reported, and the network side determines the type of information reported or the size of uplink resource according to the preamble.

Or, when there are multiple configured specific preambles, the type of the reported location information may also be determined according to the preamble group in which the target preamble is located or the related parameters of the preamble group in which the target preamble is located. In particular similar to the case where there is only one specific preamble of the above configuration. For example, if the target preamble is located in preamble group a, it indicates that the type of the uploaded location information is absolute location information or relative location information, and if the target preamble is located in preamble group B, it indicates that the type of the uploaded location information is measurement information.

Alternatively, the preamble may be combined with the preamble transmission time or the PRACH type (e.g., format0, format1, format2, format3, a1, a2, A3, B1, B2, B3, B4, C0, C1, etc.) to express a larger resource request or location information upload.

In one possible implementation, the target random access preamble sequence may also be generated according to a specific root sequence to indicate that the UE shall report the location information. Wherein, the specific root sequence may be indicated in preamble configuration information sent in msg0 by the network side. For example, the preamble configuration information may include a reach-rootsequence index (ra _ sequence index), for example, the preamble configuration information may be reach-rootsequence index _2, and the UE may generate the target ra _ sequence by using the ra _ sequence indicated by reach-rootsequence index _2, so as to indicate that location information is to be reported or an uplink resource not less than a first preset value is applied.

Alternatively, the UE may also use the target random access preamble sequence generated by the random access root sequence indicated by the reach-rootsequencenndidex or reach-rootsequencenndidex _2 and the reserved or preconfigured random access preamble sequence together to indicate that the location information is to be reported. In this possible implementation, for example, only preamble14 and preamble15 may generate a target sequence with preamble-rootsequence index _2, when preamble14 and preamble15 and a random sequence generated by preamble-rootsequence index are used to request an uplink resource not smaller than a first preset value or indicate location information reporting for an existing R16 random request, if the random sequence generated by combination with preamble-rootsequence index _2 expresses a special random request, optionally, the type of location information to be reported may also be determined according to a preamble group in which a reserved or preconfigured random access preamble sequence used by the UE is located, for example, if located in group a, the type of location information to be reported is indicated as absolute location information or relative location information, and if located in group B, the type of location information to be reported is indicated as measurement information.

In the foregoing possible implementation manner, the random access root sequence index that may be included in the preamble configuration information may be a random access root sequence index configured for a specific preamble, or a random access root sequence index configured for a specific preamble group.

In one possible implementation, the target random access preamble sequence may be generated by a specific preamble sequence carrying parameters. The preamble sequence carrying parameter may be configured through configuration information sent by the network side, for example, the network side may carry a new parameter in preamble configuration information of msg0, where the new parameter is the preamble sequence carrying parameter, or may set a value of an original certain parameter as a predetermined value to indicate that the UE will report the location information in a predetermined message in the random access process.

Alternatively, in a possible implementation manner, the target random access preamble sequence may also be generated by a generation rule of non-discrete Fourier transform Spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) or by a Gold sequence, so as to indicate that the UE shall report the location information in a predetermined message of the random access procedure. That is, a sequence different from the current R16ZC sequence is sent to express the reported location information or the uplink resource request not less than the first preset value in the random process.

In one possible implementation, the sending the target Random Access preamble sequence refers to sending a Random Access sequence on a predetermined Random Access opportunity (RO) resource to indicate that the UE shall report the location information in a predetermined message of a Random Access procedure. Therefore, in this possible implementation manner, the transmitting the target random access preamble sequence in S110 may include: and sending the target random access preamble sequence on a predetermined RO resource, wherein the predetermined RO resource can be configured in the configuration information sent by the network side. For example, the network side may carry indication information indicating the predetermined RO resource in msg0 of the random access procedure, or further carry association information between the RO resource and the uplink resource, for example, the optional preamble on RO1 indicates resource allocation greater than preset value 1, and the optional preamble on RO2 indicates resource allocation greater than preset value 2.

In the possible implementation manner, a predetermined RO resource may be applied to indicate that a predetermined message sent by the UE in the random access process carries location information. In this possible implementation, any preamble sent on the predetermined RO resource indicates that the information reported by the UE in the predetermined message includes location information.

In the foregoing possible implementation manner, optionally, the target preamble sent on the predetermined RO resource may be a specific preamble, so as to indicate that the information reported by the UE in the predetermined message includes location information; or, sending a random preamble on the predetermined RO resource, where the random preamble may be a preamble of a specific group, so as to indicate that information reported by the UE in the predetermined message includes location information; or, the random preamble sent on the predetermined RO resource may be of a specific type, so as to indicate that the information reported by the UE in the predetermined message includes location information. For example, type 1(type1) preamble in 4-step RACH or type 2(type 2) preamble in 2-step RACH; or, the random preamble transmitted on the predetermined RO resource may be a specific type (e.g., type1 in 4-step RACH or type 2 in 2-step RACH), so as to indicate that the information reported by the UE in the predetermined message includes location information. The concrete can be determined according to the practical application.

In the foregoing possible implementation manner, in order to enable the uplink resource allocated by the network side to be used for uploading the location information, the network side may associate, with each random preamble corresponding to the predetermined RO resource, a larger time-frequency resource (PO) for uplink data transmission, that is, a PO resource associated with the predetermined RO resource is greater than the second preset value. Optionally, the association manner configures a group of ROs and POs or configures an association table of ROs and POs for the network side, and optionally, in a special case, one RO may configure one or more POs.

In one possible implementation, the random access procedure may be a 4-step RACH, and the predetermined message is msg3, and S110 includes: the target random access preamble sequence is sent in msg 1. That is, in this possible implementation, the UE in the non-connected state sends the target random access preamble sequence in msg1 by initiating a 4-step random access procedure, indicating that the UE will report the location information in msg 3. In this possible implementation manner, the first preset value is a sum of a resource occupied by the location information to be reported and a resource occupied by the access information in the msg3, or a number of information bits or a number of resources agreed in advance by a protocol. That is, the UE indicates that the uplink resource allocated by the network side for msg3 should be no less than the sum of the resource occupied by the location information that needs to be reported and the resource occupied by the access information that needs to be carried in msg 3. That is, the UE expects that the size of the uplink resource allocated on the network side > the size of the location information to be uploaded + the original information size of msg 3.

For example, the number of Resource Blocks (RBs) in the frequency domain of the uplink Resource allocated by the network exceeds the required number of the location information or the Resource number of the pre-configured location information.

Or the number of frequency domain resources and the number of RBs of time domain resources of the uplink resources exceeds the number of the position information or the number of resources of the pre-configured position information;

or the modulated bit number of the uplink resource exceeds the required number of the position information or the resource number of the preset position information. Optionally, the number of bits is greater than a threshold N, where N may be 1000 bits, 1024 bits, 2048 bits, or 2560 bits.

In one possible implementation, after transmitting msg1, the method may further include: receiving a random access response RAR-msg2 returned by the network side; and the msg3 carries the position information and reports the position information to the network side. The network side may indicate the uplink resource allocated for msg3 in the returned RAR-msg2, the UE sends msg3 on the uplink resource, and reports the location information carried in msg3 to the network side.

In one possible implementation, the manner in which the UE carries the location information in msg3 includes, but is not limited to, one of:

the location information is carried in a non-access stratum (NAS) container of the msg 3;

the location information is carried in a Data Radio Bearer (DRB) or a Signaling Radio Bearer (SRB) of the msg3, where the Data Radio Bearer carries user plane Data.

In a possible implementation manner, uplink resources returned by the network side through the RAR-msg2 may be smaller than resources required by location information that needs to be reported, in this case, any of the following manners may be adopted when sending msg 3:

repeatedly sending msg3, wherein each time of sending msg3 carries different parts of the position information to be reported;

carrying part of the position information in the position information to be reported in the msg3 and reporting to the network side;

carrying differential position information of the position information to be reported in the msg3 and reporting to a network side;

carrying the relative position information of the position information to be reported in the msg3 and reporting to the network side;

in the random access process, entering a connection state, and reporting the position information needing to be reported in the connection state;

the msg3 carries a position information request or an uplink grant (UL grant) request without reporting the position information, and requests a network side to allocate larger uplink resources;

not reporting the location information in the msg 3;

the msg3 carries position information change instruction information.

In another possible implementation manner, the random access procedure includes a 2-step RACH, the predetermined message is a Physical Uplink Shared Channel (PUSCH) message of msgA, and sending the target random access preamble sequence includes: transmitting the target random access preamble sequence in a Physical Random Access Channel (PRACH) message of msgA. In the 2-step RACH, msgA comprises a PRACH message and a PUSCH message, namely uplink data are respectively transmitted on PARCH and PUSCH, UE transmits a target preamble in the PRACH to indicate that the UE reports position information in the PUSCH, and a network side is expected to allocate uplink resources which are not less than a first preset value to the PUSCH. In this possible implementation manner, the first preset value is the sum of the resource occupied by the location information to be reported and the resource occupied by other information in the PUSCH message of the msgA.

In one possible implementation, the target preamble sent in the PRACH may be associated with a preconfigured resource, and the UE reports a location on the preconfigured resource. Wherein the pre-configured resource includes, but is not limited to, one of: a preconfigured msgA PUSCH resource; a predetermined uplink time-frequency PO resource; PUSCH resources and PO resources of a predetermined msgA.

In the foregoing possible implementation manner, the PO resource may be a PO resource associated with a predetermined RO resource that sends the target preamble, and the network side may associate one or more larger PO resources with the predetermined RO resource during configuration, for example, the PO resource may be larger than the second preset value.

In one possible implementation, the reporting of the location information on the preconfigured resource includes, but is not limited to, one of the following:

reporting the position information carried in the PUSCH message of the MsgA to a network side; the position information is directly carried in the PUSCH message of the MsgA and is sent;

carrying the position information in an NAS message container and reporting the position information to a network side; carrying the position information in an NAS message container, and sending the NAS message in a PUSCH message of MsgA;

the position information is carried in a predetermined DRB or SRB and reported to a network side; namely, the position information is carried in the predetermined DRB or SRB, and the predetermined DRB or SRB is sent in the PUSCH message of the MsgA.

In a possible implementation manner, the preconfigured resource may be smaller than a resource occupied by the location information to be reported, and when the predetermined message is sent, one of the following manners may be adopted:

repeatedly sending the MSgA PUSCH message on the preconfigured resource, wherein the MSgA PUSCH message sent each time carries different parts of the position information needing to be reported;

reporting part of the position information to be reported to a network side on the pre-configured resource;

reporting the differential position information of the position information to be reported to a network side on the pre-configured resource;

reporting the relative position information of the position information to be reported to a network side on the pre-configured resource;

sending a location information request or a UL grant request on the pre-configured resource without reporting the location information;

not reporting the location information;

and reporting position information change indication information on the preconfigured resources. Wherein the location information change indication indicates whether the UE has moved or moved outside a certain range.

In a possible implementation manner, when the location information to be reported includes location measurement information, where the measurement information may be Reference Signal Time Difference (RSTD), further, the target random access preamble sequence may be determined according to a type of the RSTD to be reported. For example, the network side may pre-regroup the target random sequence according to various types of the reported RSTDs, and the UE may select a corresponding preamble as the target preamble or select a corresponding RO resource as the RO resource for sending the preamble according to the type of the RSTD to be reported.

In a possible implementation manner, if the UE reports to the network side through the NAS message container carrying the location information, the UE may indicate, through an NAS message container identifier, whether to transmit the location information to an Access Control and Mobility Management Function (AMF) entity or another entity on the network side.

In a possible implementation manner, the location information reported by the UE may include longitude and latitude coordinates, and the precision of the longitude and latitude coordinates is similar to the result reported by the GPS. The location information reported by the UE may also be location indication or location change indication information, for example, the location state of the normal UE may be indicated by the information, such as whether the UE leaves a frequent or safe activity range; or relative position information, when the uplink resource is limited, if the uplink resource does not meet the first preset value but meets a fourth preset value (the minimum number of resource reported at the position), reporting differential position information, wherein the differential position information can be the difference of the result reported at the previous time or the difference of the result at the current time. The position information format can be determined by network side configuration or protocol convention or by combination of the network side configuration and the protocol convention.

In one possible implementation, if the UE has a small moving range or is in a normal activity range (e.g., three points in one line for home, work, and social), the UE may be defined as being in a normal state, i.e., a normal UE. For normal UE, the positioning assistance data packet may be all positioning assistance information in its normal state, so as to complete positioning in idle and inactive states; the cell, resource set and resource in the positioning auxiliary information can be mapped in an array mode, and if the positioning auxiliary data is larger than the data to be measured, the UE converges and determines the information to be measured and reported according to the PBCH measurement information of the cell in which the UE is located; in addition, if the reported RSTD is the difference RSTD, a corresponding resource indication mode adopts a difference bit indication method.

In addition, the normal UE may determine whether the location and the serving cell to which the UE belongs are in the assistance data.

In one possible implementation, the UE location information may be the result of relaxed measurements and reporting. For example, if there is an external trigger report, but the measurement and location result of the UE does not reach the condition of triggering to enter the connected state, then: (1) when the small data transmission is finished or the connection state is refused to enter, the UE is informed of being triggered to report the position information; (2) if the UE is not triggered to report when the time is longer than the threshold value and the position does not move beyond the threshold value or is always in a normal state, the UE enters a relaxation measurement and relaxation reporting state; and informing the position server when reporting next time, relaxing the measured parameters, and if the positioning result is reasonable, considering that the positioning auxiliary data is effective.

In one possible implementation, before the UE obtains the location information, the positioning assistance data may be obtained by:

a) if the idle-state UE has not entered the connected state before and acquired the positioning assistance data and has not been authenticated the security zone, the UE may request to broadcast the positioning assistance data or issue the positioning assistance data through small data (in the UE non-connected state). In this case, this positioning assistance data is generic and does not have the characteristics of a per ue.

b) If the UE positioning auxiliary data which enters the connected state fails, if the UE positioning auxiliary data in the normal state fails, or the positioning result exceeds a threshold value and a range, if the user is a child or an old person needing attention, establishing connection and informing a guardian; if the UE of the other user is the UE of the other user, the idle state is tried to acquire the positioning assistance data, for example, the positioning assistance data is requested to be broadcasted through the on demand SI, or the positioning assistance data is issued through small data (in the UE non-connection state). In this case the positioning assistance data is generic and does not have the characteristics of a per ue.

By the method provided by the embodiment of the invention, when the UE is in the non-connection state, the position information can be reported through the random access process, the network side is instructed to distribute reasonable uplink resources, and the position information report can be correspondingly processed when the uplink resources are not distributed sufficiently.

Fig. 2 is another flowchart illustrating a method for processing a random access procedure according to an embodiment of the present invention, where the method 200 may be executed by a network device. In other words, the method may be performed by software or hardware installed on the network device. As shown in fig. 2, the method may include the following steps.

S210, in the random access process of a terminal device, receiving a target random access leader sequence sent by the terminal device, wherein the target random access leader sequence indicates the terminal device to request an uplink resource not less than a first preset value, and the uplink resource is used for reporting uplink information in the random access process.

As described in the method 100, the UE may instruct the network device to allocate, to the terminal device, the uplink resource not smaller than the first preset value through the target preamble.

Wherein, in the 4-step RACH, the uplink resource includes: an uplink grant resource (UL grant) and/or a PUSCH resource, and in the 2-step RACH, the uplink resource includes: PO resources and/or PUSCH resources.

In one possible implementation, after S210, the method may further include: and allocating uplink resources for the terminal equipment, and indicating the allocated uplink resources through the downlink message in the random access process. For example, in 4-step RACH, after receiving a target preamble sent by the UE through msg1, the network side allocates uplink resources to the UE and indicates the UE through msg 2.

And the network equipment allocates uplink resources for the terminal equipment corresponding to the received target preamble.

In one possible implementation, the target preamble includes: and reserving or pre-configuring a random access leader sequence which is specially used for requesting to report the uplink resource of the position information. The network device allocates uplink resources corresponding to the reserved or preconfigured preamble to the UE.

Alternatively, in another possible implementation manner, the network device may also send the configuration information of the target preamble to the terminal device, for example, the network device sends the configuration information of the target preamble in msg0 of the random access procedure.

In the foregoing possible implementation manner, the configuration information of the target preamble may include: the random access preamble sequence index in the N random access preamble sequence groups, and M uplink resource thresholds. In this possible implementation, M may be equal to N, i.e. an uplink resource threshold is configured for each random access preamble sequence group; or M may also be smaller than N, in this case, the uplink resource threshold may be used as an upper limit or a lower limit of uplink resources corresponding to different random access preamble sequence groups to distinguish the different random access preamble sequence groups, for example, the network device configures two random access preamble sequence groups: group A and group B, and configuring an uplink resource threshold SizeGroup1, indicating that the maximum value of the uplink resource corresponding to group A is SizeGroup1, and the minimum value of the uplink resource corresponding to group B is SizeGroup 1; or M may also be greater than N, in this case, the network device may configure a maximum uplink resource threshold and a minimum uplink resource threshold for the uplink resource corresponding to the same random access preamble sequence group, that is, indicate that the uplink resource corresponding to one random access preamble sequence group is located between the minimum uplink resource threshold and the maximum uplink resource threshold.

Optionally, the set of random access preamble sequences comprises one of:

a first random access preamble sequence group;

the random access method comprises the steps that a first random access preamble sequence group and a second random access preamble sequence group are obtained, wherein an uplink resource threshold corresponding to the second random access preamble sequence group is larger than an uplink resource threshold corresponding to the first random access preamble sequence group;

the random access method comprises a first random access preamble sequence group, a second random access preamble sequence group and a third random access preamble sequence group, wherein an uplink resource threshold corresponding to the third random access preamble sequence group is greater than an uplink resource threshold corresponding to the second random access preamble sequence group, and an uplink resource threshold corresponding to the second random access preamble sequence group is greater than an uplink resource threshold corresponding to the first random access preamble sequence group.

The UE may select a preamble in the corresponding preamble group as the target preamble according to the uplink resource threshold of each preamble group and the resource required for reporting the location information.

Optionally, the first random access preamble sequence group includes a first preset random access preamble sequence, where the first preset random access preamble sequence indicates that the size of the uplink resource allocated to the terminal device is greater than an uplink resource threshold corresponding to the first random access preamble sequence group, and if the network device is not configured with a preamble group B, if the uplink resource threshold of the preamble group a is smaller than a first preset value, the UE may select the first preset random access preamble sequence as a target preamble; and/or the presence of a gas in the gas,

the second random access preamble sequence group comprises a second preset random access preamble sequence, and the second preset random access preamble sequence indicates that the size of the uplink resource allocated to the terminal device is larger than the uplink resource threshold corresponding to the first random access preamble sequence group or the uplink resource threshold corresponding to the second random access preamble sequence group. For example, in the case that the network device does not configure the preamble group C, if uplink resource thresholds of the preamble groups a and B are smaller than the first preset value, the UE may select the second preset random access preamble sequence as the target preamble.

In another possible implementation manner, the configuration information may include: and generating an index of a root sequence of the target random access preamble sequence. In this possible implementation manner, the network side may determine that the uplink resource needs to be allocated to the terminal device according to the received root sequence used by the target random access preamble sequence. That is, the network device may pre-configure a specific root sequence, where one uplink grant corresponding to the specific root sequence is not less than the first preset value, the network device indicates the index of the root sequence to the UE through msg0, if the UE needs to report location information or an uplink resource greater than the first preset value, the UE generates a target preamble according to the root sequence, and the network device allocates the uplink resource not less than the first preset value to the UE according to the received root sequence used by the target preamble.

In practical applications, the UE may directly use the root sequence to generate the target preamble, or the UE may also use the root sequence to generate the target preamble in combination with the reserved or preconfigured preamble.

In a specific application, the root sequence may adopt an implementation manner of the root sequence corresponding to that in the method 100, and refer to the description in the method 100 specifically.

In one possible implementation manner, the configuration information may also include: a specific preamble sequence carries parameters; the network side may determine that the uplink resource needs to be allocated to the terminal device by receiving that the target random access preamble sequence includes the specific preamble sequence carrying parameter. That is, in this possible implementation manner, the network device may pre-configure a specific preamble sequence carrying parameter, where the specific preamble sequence carrying parameter corresponds to an uplink grant not less than the first preset value, the network device indicates the specific preamble sequence carrying parameter to the UE through msg0, if the UE needs to report the location information, the UE generates a target preamble according to the preamble sequence carrying parameter, and the network device allocates an uplink resource not less than the first preset value to the UE according to the received preamble sequence carrying parameter used by the target preamble.

In one possible implementation manner, the configuration information may also include: a particular RO resource; the network side may determine to allocate the uplink resource to the predetermined message of the terminal device according to the RO resource used for sending the target random access preamble sequence. The determining of the uplink resource may further include a specific time-frequency resource and/or a coding mode of the uplink resource, that is, in the possible implementation mode, the network device may pre-configure a specific RO resource, where one uplink resource corresponding to the specific RO resource is not less than a first preset value, the network device indicates the specific RO resource to the UE through msg0, if the UE needs to report the location information, the UE sends a target preamble using the RO resource, and the network device allocates the uplink resource not less than the first preset value to the UE according to the received RO resource used by the target preamble.

In the foregoing possible implementation manner, the specific RO resource may be an associated PO resource, where the associated PO resource is greater than a first preset value; the uplink resource allocated by the network side is a PO resource corresponding to the RO resource.

In one possible implementation, the target random access preamble sequence is generated by a generation rule or Gold sequence of non-DFT-S-OFDM. That is, in this possible implementation manner, the UE instructs the network device to allocate the uplink resource to the UE according to the generation rule or the sequence used for generating the target preamble.

The random access procedure in the method 200 provided by the embodiment of the present invention may be a 4-step RACH or a 2-step RACH, and a specific implementation manner corresponds to the method 100, which may be referred to as the description in the method 100.

And will not be described in detail herein.

In one possible implementation, when the UE is in a Connection Management (CM) -idle state, if the base station (gNB) receives a NAS packet, if the NAS packet is an uplink packet, triggering the AMF to enter a CM-CONNECT state, and uploading the NAS packet; and if the NAS packet is a downlink packet, the NAS packet is sent to the UE when the UE reports the next time.

By the method provided by the embodiment of the invention, when the UE is in the non-connection state, the network equipment can allocate reasonable uplink resources for the random access process of the UE, so that the UE can report the position information in the random access process.

In other words, the method may be performed by software or hardware installed on the terminal device and the network device. As shown in fig. 3, the method may include the following steps.

As shown in fig. 3, the method is applied in 4-step RACH.

And S312, the terminal equipment sends the target preamble to the network equipment according to the configuration information.

The terminal device may select the target preamble sent to the network device according to the method described in the method 100, so that the network device may allocate sufficient uplink resources for msg3 to report the location information.

And S314, the network equipment sends msg2 RAR response to the terminal equipment, and indicates the uplink resource allocated to the terminal equipment.

The uplink resource allocated by the network device corresponds to the received target preamble, which may specifically refer to the relevant descriptions in the method 100 and the method 200.

For details, reference may be made to the related description in the method 100, and details are not described herein.

In a possible implementation manner, since the terminal device only reports the location information through the random access process, and does not need to access the network, that is, does not need to establish a connection, an indication that the connection does not need to be established may be carried in msg 3. And if the network equipment successfully receives the msg3, releasing the connection with the terminal equipment according to the indication which is carried in the msg3 and does not need to establish the connection.

Alternatively, after the network device successfully receives the location information, it determines that no other information is reported, and then releases the connection with the terminal device in msg 4.

Reference may be made specifically to the above description of method 100 and method 200.

In the PUSCH process, the terminal equipment sends an RRC connection request and carries position information, wherein uplink resources in the PUSCH process are associated with the target preamble.

In one possible implementation manner, before S410, the network device may send msg0 to the UE, where msg0 carries preamble configuration information. The preamble configuration information may adopt various possible implementation manners of the preamble configuration information of the methods 100 to 300, which are not described herein again.

The Msg B includes identification information of the communication device in the successfully received MsgA, for example, RA-RNTI, and time synchronization information. The time synchronization information may include TA (Timing Advance) information and the like. If the terminal equipment successfully receives an RAR within the RAR time window and the preamble index (sequence number) in the RAR is the same as the target preamble index sent by the UE, the RAR is considered to be successfully received.
