In order to facilitate understanding of the technical solution of the embodiments of the present application, the technical solution of the present application is described in detail below through specific embodiments. The following related technologies may be optionally combined with the technical solutions of the embodiments of the present application, which all belong to the protection scope of the embodiments of the present application. Embodiments of the present application include at least some of the following.

In the 5G NR system, radio resource control (Radio Resource Control, RRC) states are divided into 3 types, respectively: an RRC IDLE (rrc_idle) state, an RRC INACTIVE state, or an RRC deactivated (rrc_inactive) state, and an RRC CONNECTED (rrc_connected) state. Wherein the rrc_inactive state is a new state introduced by the 5G system from the energy saving point of view, for the terminal in the rrc_inactive state, radio bearers and all radio resources are released, but the terminal side and the base station side reserve the terminal access context in order to quickly restore the RRC connection, and the network generally maintains the terminal in the rrc_inactive state where data transmission is not frequent. In some embodiments, the terminal in rrc_inactive state may perform small data Transmission (SMALL DATA Transmission, SDT), for example, the terminal device may perform uplink small data Transmission based on a random access procedure (two-step random access and/or four-step random access).

In some embodiments, for a terminal in the rrc_inactive state, the SDT is triggered when the following condition is met:

The data to be transmitted comes from radio bearers that may trigger SDT, e.g., signaling radio bearers (SIGNALING RADIO BEARERS, SRB) and/or data radio bearers (Data Radio Bearer, DRB);

The data quantity to be transmitted is smaller than the network preconfigured data quantity threshold;

The downlink reference signal received Power (REFERENCE SIGNAL RECEIVED Power, RSRP) measurement result is greater than the network preconfigured RSRP threshold;

There are valid SDT resources, e.g., random access SDT (Random ACCESS SDT, RA-SDT) resources and/or Configured Grant SDT (CG-SDT) resources.

In some embodiments, if the terminal is configured with RA-SDT resources and CG-SDT resources at the same time, the terminal preferentially determines whether the CG-SDT resources are valid, where the determining conditions include:

There is a valid timing advance (TIMING ADVANCE, TA), the determination includes: the SDT-TA timer (SDT-TAT) is in an operating state, and/or the RSRP variation does not exceed a pre-configured threshold;

CG-SDT resources are present on the selected carrier (Normal Uplink (NUL) or supplemental Uplink (Supplementary Uplink, SUL));

CG-SDT resources are present on the selected synchronization signal block (Synchronization Signal Block, SSB).

Specifically, if the above conditions of the terminal cannot be met, the terminal further determines whether the RA-SDT resource is valid, and if so, initiates the RA-SDT procedure, that is, the terminal performs random access to use a first Message (Message a, msg a) in two-step random access to fill (payload) a field or a third Message (Message 3, msg 3) in four-step random access to send small data to the network. Otherwise, initiate the RRC recovery procedure.

In some embodiments, during SDT, the terminal considers the SDT to fail and enters an RRC IDLE (rrc_idle) state when encountering the following events:

Cell reselection occurs during SDT;

The SDT failure detection timer (SDT failure detection timer) times out;

The radio link control (Radio Link Control, RLC) reaches a maximum number of transmissions, i.e. RLC failure is detected.

For better understanding of the embodiments of the present application, a Self-organizing network (Self-Organizing Network, SON) related to the present application will be described.

The SON can optimize the network parameter configuration according to the information reported by the terminal device, and the signaling flow can be shown in fig. 2. Specifically, the network device sends a terminal information request (UEInformationRequest) to the terminal device in a connected state, and UEInformationRequest includes information types that the network device needs to report by the terminal device, for example, a random access report request (ra-ReportReq), an RLF report request (RLF-ReportReq), and the like.

Taking a random access report request (ra-ReportReq) as an example, the following network device sends a terminal information request (UEInformationRequest) to the terminal device, and the random access report request (ra-ReportReq) indicates that the network device needs the terminal device to report information related to a random result process when ra-ReportReq is true. The terminal device feeds back a corresponding type of report to the network through a terminal information response (UEInformationResponse) message according to the indication of the network device.

The terminal information request (UEInformationRequest) may be the following syntax element, for example.

Illustratively, the terminal information response (UEInformationResponse) may be the following syntax element.

In some embodiments, the terminal device triggers the recording of the above-mentioned various types of reports for different events. Taking a random access Report (ra-Report) as an example, the terminal device stores random access procedure information in a random access Report parameter (VarRA-Report) list maintained by the terminal device after each successful completion of random access. When receiving the report request from the network side, reporting the recorded random access report to the network equipment.

In some embodiments, the generation condition of the random access report is: the terminal completes the random access successfully.

The random access report may include the following information elements (Information element, IE):

A cell Identity (ID) where random access is located;

purpose of random access: access related (ACCESS RELATED), beam failure recovery (beamFailureRecovery), synchronization reconfiguration (reconfigurationWithSync), uplink out-of-sync (ulUnsynchronized), scheduling request failure (schedulingRequestFailure), no physical uplink control channel (Physical Uplink Control Channel, PUCCH) resources available (noPUCCHResourceAvailable), request for other system information (requestForOtherSI);

Frequency position of a bandwidth part (Band WIDTH PART, BWP) for performing random access, subcarrier information, random access opportunity (Random Access Occasion, RO) Frequency Division Multiplexing (FDM) number information;

Specific random access case: SSB index, number of random access attempts under each SSB, whether the random access attempt encounters collision (collision), whether the target SSB is above the RSRP threshold of the SSB (RSRP-ThresholdSSB).

In some embodiments, when transmitting the SDT using random access, the network device may configure a different competing random access procedure (Contention Based Random Access, CBRA) random access resource, such as a sequence code, a random access time-frequency domain resource, etc., for the SDT than for random access performed for other reasons.

In order to facilitate a better understanding of the embodiments of the present application, the problems addressed by the present application will be described.

The current random access report cannot accurately inform the network whether the random access is performed by the terminal because the small data packet is transmitted, if the problem that the terminal performs the random access to transmit the small data packet always collides occurs, the network cannot correspondingly adjust the random access resource allocation for the transmission of the small data packet.

Based on the above-mentioned problems, the present application proposes a scheme for small data transmission, in which a terminal device can instruct, in a random access report, that a purpose of performing random access is small data transmission, so that a network device can determine whether to perform optimization adjustment on random access resources for small data transmission based on the random access report, thereby optimizing small data transmission.

The technical scheme of the application is described in detail below through specific embodiments.

Fig. 3 is a schematic flow chart of a method 200 of wireless communication according to an embodiment of the application, as shown in fig. 3, the method 200 of wireless communication may include at least some of the following:

S210, terminal equipment sends a random access report to network equipment; the random access report comprises first indication information, wherein the first indication information is used for indicating that the purpose of executing random access is SDT;

s220, the network equipment receives the random access report sent by the terminal equipment.

In the embodiment of the application, the terminal equipment reports the random access report, and the first indication information included in the random access report is used for indicating that the purpose of executing random access is SDT, so that the network equipment can determine whether to optimally adjust the random access resource for small data transmission based on the random access report, thereby optimizing the small data transmission.

In some embodiments, the terminal device may actively send a random access report to the network device.

In some embodiments, the terminal device may send a random access report to the network device at the request of the network device. For example, it may correspond to a self-organizing network (SON) as shown in fig. 2.

In some embodiments, the first indication information is a field in a random access destination Information Element (IE) in the random access report. Of course, the first indication information may also be a field in other Information Elements (IEs) in the random access report. The application is not limited in this regard.

In some embodiments, the random access report further includes second indication information; the second indication information is used for indicating that the number of times of random access conflict resolution failure in random access aiming at the SDT is larger than or equal to a first threshold value, or the second indication information is used for indicating that the number of times of collision in random access aiming at the SDT is larger than or equal to a second threshold value.

In some embodiments, the first threshold value may be agreed upon by a protocol, or the first threshold value may be configured by a network device. For example, the first threshold value is 3, or 4, or 5, or 6, or 7.

In some embodiments, the second threshold may be agreed upon by the protocol, or the second threshold may be configured by the network device. For example, the second threshold value is 3, or 4, or 5, or 6, or 7.

In some embodiments, the second indication information is a field in a specific random access case Information Element (IE) in the random access report. Of course, the second indication information may also be a field in other Information Elements (IEs) in the random access report. The application is not limited in this regard.

In some embodiments, the relevant parameters for random access for SDT include, but are not limited to, at least one of:

a random access preamble, a random access time-frequency domain resource.

In some embodiments, the number of random access preambles configured or updated based on the configuration information is greater than or equal to a third threshold value.

In some embodiments, the third threshold value may be agreed upon by the protocol, or the third threshold value may be configured by the network device. For example, the third threshold value is 4, or 5, or 6, or 7, or 8.

Specifically, for example, the network device configures 2 random access preambles on each RO for the terminal device for random access; in the process that the terminal equipment executes random access to send SDT to the network equipment, a plurality of terminals experience at least six random access conflict resolution failures (such as Msg A or Msg3 sending collision) before successfully sending small data packets to the network equipment; the terminal equipment stores the random access condition in a random access report and sends the random access condition to the network equipment; the network device appropriately increases the number of random access preambles used for SDT transmission, for example, from 2 to 5, according to the SDT random access Msg a or Msg3 collision condition reflected by the terminal device in the random access report.

Therefore, in the embodiment of the present application, the terminal device reports the random access report, and the first indication information included in the random access report is used to indicate that the purpose of performing random access is SDT, so that the network device can determine whether to adjust the random access resource for small data transmission based on the random access report, thereby optimizing the small data transmission.
