The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU.

[0128] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0129] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0130] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0131] In NR, to better obtain channel state information, the terminal needs to measure CSI-RS and report the CSI information obtained based on CSI-RS, or the terminal sends SRS and the base station measures the SRS to obtain channel state information. However, currently these operations all require the terminal to be in connected state.

[0132] The current problem is that for idle or inactive terminals, when a terminal needs to transmit data, it must first enter the connected state, that is, after the Radio Resource Control (RRC) connection is established, before triggering CSI-RS measurements or SRS transmission for CSI. Only after the base station obtains the CSI information can it determine an appropriate Modulation and Coding Scheme (MCS) to schedule data transmission. Otherwise, the base station can only schedule data transmission based on the default CSI. If the default CSI is poor, the terminal transmission rate is low; if the default CSI is high, the decoding success rate is low, resulting in a low transmission rate.

[0133] To address the aforementioned issues, this disclosure proposes a communication method. This method involves the terminal measuring and reporting the CSI of the serving cell before entering the connected state, ensuring that the terminal can perform data scheduling as quickly as possible based on the accurate CSI after the connection is established, thereby improving the data transmission rate. The specific details of this method are as follows.

[0134] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method for a communication system 100, which may include a terminal 101 and a network device 102. The method includes:

[0135] Step 2101: The terminal determines the reference signal resource.

[0136] In some embodiments, reference signals can be received or transmitted on reference signal resources. For example, a network device can transmit reference signals to a terminal on reference signal resources, and a terminal can receive reference signals on reference signal resources.

[0137] In some embodiments, the reference signal resource may optionally be a CSI-RS resource, or the first reference resource may be a Synchronization Signal Block (SSB), a Physical Broadcast Channel Block, or a Tracking Reference Signal (CSI-RS for tracking, TRS).

[0138] In some embodiments, the reference signal includes at least one of the following: a synchronization signal block SSB; a tracking reference signal TRS; and a CSI reference signal (Channel State Information Reference Signal, CSI-RS).

[0139] The Tracking Reference Signal (TRS) can be used for precise time-frequency domain synchronization between the terminal and network devices in idle, deactivated, or connected states. TRS is also a type of CSI-RS, and the corresponding CSI-RS resource set is configured with TRS information. Furthermore, this CSI-RS resource supports specific modes such as single-antenna port and non-zero-power (NZP) CSI-RS configuration with a frequency domain density of 3.

[0140] In other words, the terminal can determine the resources for receiving reference signals. Optionally, after receiving the reference signal through the reference signal resources, the terminal can perform channel state information measurement based on the reference signal.

[0141] In some embodiments, determining the reference signal resource includes determining the reference signal resource before the terminal enters the connected state. Optionally, the terminal may be a terminal in an idle state or a deactivated state.

[0142] In some embodiments, determining the reference signal resource includes: obtaining configuration information of the reference signal resource when the terminal enters a deactivated state from a connected state, and then determining the reference signal resource based on the configuration information during the process of the terminal entering a connected state from a deactivated state. Optionally, when determining the first information, the terminal may be a terminal in an idle state or a deactivated state.

[0143] In other words, the terminal can receive reference signals sent by network devices through reference signal resources when it is in a disconnected state. The disconnected state can include an idle state and a deactivated state. That is, when the terminal is in an idle state or a deactivated state, it can receive reference signals and perform measurements and reports based on the reference signals. This enables the measurement and reporting of channel state information in advance. It also enables the terminal to measure and report the channel state information (CSI) of the serving cell when it is in a disconnected state. This ensures that after the connection is established, the terminal can quickly perform data scheduling based on accurate CSI, thereby improving the data transmission rate.

[0144] In some embodiments, the terminal may optionally determine the reference signal resource in any of the following ways.

[0145] Method 1

[0146] In some embodiments, determining the reference signal resource includes: determining the reference signal resource based on protocol predefined definitions.

[0147] In some embodiments, the method further includes: receiving fourth information sent by a network device, the fourth information being used to trigger a terminal to obtain first information based on a reference signal on a reference signal resource.

[0148] In some embodiments, the fourth information may optionally be information indicated by the CSI request field. Optionally, the fourth information may contain at least one bit, and the value of the bit may be used to instruct the terminal to obtain the first information based on the reference signal on the reference signal resource. For example, when the bit value contained in the fourth information is 1, the terminal may be instructed to obtain the first information based on the reference signal on the reference signal resource.

[0149] In some embodiments, optionally, the reference signal resource can be determined according to a predefined protocol. For example, when the reference signal is an SSB, the protocol can predefine the resource configuration of the SSB. The CSI request field triggers the terminal to receive the SSB at that resource location and obtain CSI based on the SSB for reporting. In other words, the resource for receiving the reference signal can be determined according to the protocol indication.

[0150] In some embodiments, optionally, the reference signal resource can be determined according to a predefined protocol. For example, when the reference signal is a TRS, the protocol can predefine the resource configuration of the TRS. The CSI request field triggers the terminal to receive the TRS at that resource location and obtain CSI based on the TRS for reporting. In other words, the resource for receiving the reference signal can be determined according to the protocol indication. Optionally, the quasi-colocation source (QCL source) of the TRS signal can be the same as the SSB corresponding to the random access resource.

[0151] In some embodiments, optionally, a reference signal resource can be determined according to a predefined protocol. For example, when the reference signal is CSI-RS, the protocol can predefine a CSI-RS resource configuration. The CSI request field triggers the terminal to receive CSI-RS at that resource location and report CSI based on the CSI-RS. In other words, the resource for receiving the reference signal can be determined according to the protocol indication. Optionally, the quasi-colocation source (QCL source) of the CSI-RS signal can be the same as the SSB corresponding to the random access resource.

[0152] In some embodiments, optionally, the network device may not send the fourth information to the terminal. In this case, the terminal can determine the reference signal resource according to the protocol predefined, and the terminal can directly report after obtaining the CSI according to the reference signal. That is, the terminal can report the CSI information without the network device triggering it.

[0153] Optionally, the fourth information or CSIrequestfield can be an indicator field in DCIformat0_1 / 0_2 / 0_3, or a CSIrequestfield newly introduced in DCIformat0_0.

[0154] Method 2

[0155] In some embodiments, determining the reference signal resource includes: receiving fifth information sent by a network device; and determining the reference signal resource based on the mapping relationship between the fifth information and multiple resource configuration information predefined by the protocol.

[0156] In some embodiments, the fifth piece of information may optionally be a codepoint indicated by the CSI request field; in other words, the CSI request field may indicate a codepoint.

[0157] In some embodiments, the reference signal resource can be determined according to protocol predefined and network indication. For example, when the reference signal is CSI-RS, the protocol can predefine one or more CSI-RS resource configurations, the network indicates the codepoint through the CSI request field, and the terminal implicitly or explicitly determines the triggered CSI-RS resource configuration based on the mapping relationship. The mapping relationship can be a mapping relationship between the codepoint and one or more CSI-RS resources, and the QCL source of the CSI-RS signal can be the same as the SSB corresponding to the random access resource.

[0158] In some embodiments, the reference signal resource can be determined according to protocol predefined and network indication. For example, when the reference signal is an SSB, the protocol can predefined one or more SSB resource configurations. The network device indicates the codepoint through the CSI request field, and the terminal implicitly or explicitly determines the triggered SSB resource configuration based on the mapping relationship, wherein the mapping relationship can be a mapping relationship between the codepoint and one or more SSB resources.

[0159] In some embodiments, optionally, a reference signal resource can be determined based on protocol predefined parameters and network indications. For example, when the reference signal is a TRS, the protocol can predefined one or more TRS resource configurations. The network device indicates a codepoint via a CSI request field, and the terminal implicitly or explicitly determines the triggered TRS resource configuration based on a mapping relationship, where the mapping relationship can be a mapping relationship between a codepoint and one or more TRS resources. Optionally, the QCL source of the TRS signal can be the same as the SSB corresponding to the random access resource.

[0160] In other words, the protocol can predefine one or more reference signal resources, and the terminal can determine the mapping relationship between code points and reference signal resources. Through the code points indicated by the network device, the corresponding reference signal resources can be determined, thereby determining the reference signal resources used to receive reference signals.

[0161] Optionally, the fifth information or CSIrequestfield can be an indicator field in DCIformat0_1 / 0_2 / 0_3, or a CSIrequestfield newly introduced in DCIformat0_0.

[0162] Method 3

[0163] In some embodiments, determining a reference signal resource includes at least one of the following: receiving a message sent by a network device, the message including one or more resource configuration information; receiving fifth information sent by the network device; and determining the reference signal resource based on the mapping relationship between the fifth information and one or more resource configuration information.

[0164] Optionally, the terminal may receive messages sent by the network device and determine reference signal resources based on the messages, wherein the messages include at least one of the following: system messages; downlink messages during random access; and radio resource control (RRC) messages sent by the network device when the terminal enters the deactivation state from the connected state.

[0165] Among them, system messages may be, for example, Master Information Block (MIB) or System Information Blocks (SIB); downlink messages during random access may be, for example, Msg 2, Msg 4, or Msg B; and Radio Resource Control (RRC) messages sent by the network device when the terminal enters the deactivated state from the connected state may be, for example, RRC release messages.

[0166] In some embodiments, the message may provide one or more reference signal resources. The terminal may determine the mapping relationship between code points and reference signal resources, and determine the corresponding reference signal resources through the code points indicated by the network device, thereby determining the reference signal resources used to receive reference signals.

[0167] Optionally, when the message is a system message, such as a MIB or SIB, the MIB or SIB may provide one or more CSI-RS resource configurations. The CSI request field indicates a codepoint, which is used to trigger the terminal to obtain CSI and report it based on the CSI-RS resource configuration. The terminal implicitly or explicitly determines the triggered CSI-RS resource configuration based on the mapping relationship. Optionally, the quasi-colocation source (QCL source) of the CSI-RS signal may be the same as the SSB corresponding to the random access resource.

[0168] Optionally, when the message is a system message, such as a MIB or SIB, the MIB or SIB may provide one or more TRS resource configurations. Optionally, the CSI request field indicates a codepoint, used to trigger the terminal to obtain CSI based on the TRS resource configuration and report it. Optionally, the quasi-colocation source (QCL source) of the TRS signal may be the same as the SSB corresponding to the random access resource.

[0169] Optionally, the fifth information or CSIrequestfield can be an indicator field in DCIformat0_1 / 0_2 / 0_3, or a CSIrequestfield newly introduced in DCIformat0_0.

[0170] Method 4

[0171] In some embodiments, optionally, when receiving a message according to the method of Method 3 described above, if the message is a downlink message during a random access procedure and the reference signal is CSI-RS, and the message is Msg 2, Msg 4, or Msg B, the PDSCH of Msg 2, Msg 4, or Msg B can provide one or more CSI-RS resource configurations. The CSI request field in the ULDCI indicates the codepoint, and the terminal implicitly or explicitly determines the triggered CSI-RS resource configuration based on the mapping relationship. Here, ULDCI can be the DCI corresponding to RARULgrant.

[0172] The fifth piece of information can be a CSI request field indicating a codepoint, and the mapping relationship can be a mapping relationship between a codepoint and one or more CSI-RS resources.

[0173] Optionally, the fifth information or CSIrequestfield can be an indicator field in DCIformat0_1 / 0_2 / 0_3, or a CSIrequestfield newly introduced in DCIformat0_0.

[0174] Method 5

[0175] In some embodiments, optionally, the message is received according to the method of method 3 above. When the message is a Radio Resource Control (RRC) message sent by the network device when the terminal enters the deactivated state from the connected state, and the reference signal is CSI-RS, in the case of an RRC release message, the network device may provide one or more CSI-RS resource configurations in the RRC release information when the terminal enters the deactivated state from the RRC connected state. The CSI request field indicates the codepoint, and the terminal implicitly or explicitly determines the triggered CSI-RS resource configuration based on the mapping relationship.

[0176] The fifth piece of information can be a CSI request field indicating a codepoint, and the mapping relationship can be a mapping relationship between a codepoint and one or more CSI-RS resources.

[0177] Optionally, the fifth information or CSIrequestfield can be an indicator field in DCIformat0_1 / 0_2 / 0_3, or a CSIrequestfield newly introduced in DCIformat0_0.

[0178] Step 2102: The terminal determines the first information based on the reference signal on the reference signal resource.

[0179] In some embodiments, the first information may be information related to Channel State Information (CSI), that is, the terminal can measure the channel state information based on the reference signal to obtain the corresponding channel state information.

[0180] Optionally, the terminal can determine the first information based on the reference signal before entering the connected state. That is, the terminal can measure the channel state information in advance in the non-connected state, which facilitates reporting the first information before accessing the connected state. Optionally, the terminal reporting the first information before entering the connected state can enable the terminal to measure and report the CSI of the serving cell in the non-connected state. This can ensure that after the connection is established, the terminal can quickly perform data scheduling based on the accurate CSI, thereby improving the data transmission rate.

[0181] In some embodiments, the first information includes at least one of the following: Precoding Matrix Indicator (PMI); Rank Indicator (RI); Channel Quality Indicator (CQI); Layer Indicator (LI); CSI-RS resource indicator; SSB resource indicator (SRI).

[0182] In other words, the terminal can determine at least one of the following based on the reference signal: Precoding Matrix Indicator (PMI); Rank Indicator (RI); Channel Quality Indicator (CQI); Layer Indicator (LI); CSI-RS Resource Indicator (CSI-RS); and SSB Resource Indicator (SRI) to determine information related to the channel state.

[0183] Step 2103: The terminal sends the first information to the network device.

[0184] In some embodiments, the terminal may report first information to the network device before entering the connected state, so that the terminal can perform data scheduling as soon as possible based on accurate CSI after the connection is established, thereby improving the data transmission rate.

[0185] In some embodiments, the network device may optionally instruct the terminal to report channel state-related information, that is, the terminal may report first information in a disconnected state after receiving the instruction from the network device.

[0186] In some embodiments, the method further includes: receiving third information sent by a network device, the third information being used to instruct the terminal to send first information.

[0187] In some embodiments, the third information may optionally be information carried in the Channel State Information Request field (CSI request field), wherein the third information is indicated by a field that is a field in the Downlink Control Information (DCI) corresponding to the Random Access Feedback Uplink Grant (RAR UL grant).

[0188] In some embodiments, sending first information from a terminal to a network device includes sending first information to the network device via the Physical Uplink Shared Channel (PUSCH).

[0189] In other words, the terminal can report channel state information to the network device through the physical uplink channel. The PUSCH includes at least one of the following: the PUSCH during the random access process; the PUSCH of the configured grant (CG); and the first PUSCH after the random access is completed.

[0190] In some embodiments, the PUSCH in the random access process may optionally be the PUSCH resource of Msg A or Msg 3 in the random access process; the first PUSCH after the random access is completed may be the first PUSCH message after the acknowledgment message in the random access process, for example, the first PUSCH message after Msg B or Msg4.

[0191] In some embodiments, the terminal may determine the Physical Uplink Shared Channel (PUSCH) to facilitate sending first information to the network device via the PUSCH. The terminal may determine the PUSCH using any of the following methods.

[0192] Method 6

[0193] In some embodiments, the method further includes: receiving second information sent by a network device, the second information indicating the resources of the PUSCH; and determining the resources of the PUSCH based on the second information.

[0194] In some embodiments, the second information includes at least one of the following: broadcast information; system information; downlink control information (DCI); and resource configuration information, wherein the resource configuration information is configured by the network device when the terminal transitions from a connected state to a disconnected state.

[0195] In other words, the network device can indicate the PUSCH resources to the terminal through the second information. Optionally, when the second information is broadcast information or system information, such as MIB or SIB, the PUSCH resources can be determined based on the MIB or SIB. In this case, the PUSCH resources can be the PUSCH resources of Msg A.

[0196] Method 7

[0197] In some embodiments, the method further includes: receiving second information sent by a network device, the second information indicating the resources of the PUSCH; and determining the resources of the PUSCH based on the second information.

[0198] Optionally, when the second information is downlink control information, for example, the second information can be the DCI corresponding to Msg 2 RAR UL grant. In this case, the PUSCH resources can be determined according to the DCI corresponding to Msg 2 Random-Access Response uplink grant (RAR UL grant). The PUSCH resources can be the PUSCH resources of Msg 3.

[0199] Method 8

[0200] In some embodiments, the method further includes: receiving second information sent by a network device, the second information indicating the resources of the PUSCH; and determining the resources of the PUSCH based on the second information.

[0201] Optionally, when the second information is resource configuration information, which is configured by the network device when the terminal enters the non-connected state, the PUSCH resource can be the PUSCH of the configuration authorization CG. In this case, the PUSCH of the configuration authorization CG can be determined based on the resource configuration information.

[0202] Method 9

[0203] In some embodiments, when the PUSCH resource is the first PUSCH after random access is completed, the first PUSCH after random access is completed includes at least one of the following: a dynamically authorized PUSCH scheduled by the network device through DCI; or a CG PUSCH configured by the network device.

[0204] In other words, the terminal can determine that the first PUSCH after random access is completed is the physical uplink shared channel PUSCH resource used to send the first information. Optionally, the physical uplink shared channel PUSCH resource type used to send the first information can be a dynamically authorized PUSCH scheduled by the network device through DCI, or it can be a CG PUSCH configured by the network device.

[0205] Method 10

[0206] In some embodiments, when the PUSCH resource is a PUSCH in the random access procedure, the PUSCH in the random access procedure includes at least one of the following: the PUSCH in Msg 3 in the random access procedure; the PUSCH in MsgA in the random access procedure.

[0207] In other words, the terminal can determine that the PUSCH in the random access procedure is the physical uplink shared channel PUSCH resource used to send the first information. Optionally, the type of physical uplink shared channel PUSCH resource used to send the first information can be the PUSCH in Msg3 in the random access procedure, or it can be the PUSCH in MsgA in the random access procedure.

[0208] In some embodiments, the method further includes: sending a random access preamble to a network device on the time-frequency resource corresponding to the random access opportunity (RO), wherein the RO or the preamble corresponds to a first type of random access procedure, or a second type of random access procedure, or a feature, and the feature is used to report first information.

[0209] Optionally, the first type of random access procedure may be, for example, a 4-step random access procedure, and the second type of random access procedure may be, for example, a 2-step random access procedure. The feature is used to report the first information, such as the feature may be used to report the early CSI, that is, the network device has configured the feature with the corresponding random access preamble and / or RO.

[0210] In other words, the terminal can send a random access preamble to the network device on the time-frequency resource corresponding to the random access point (RO). This makes it easier to determine the random access process and thus determine the PUSCH resource in the random access process, or the first PUSCH resource after the random access process is completed, etc.

[0211] In some embodiments, at least one of the above methods can be used to enable the terminal to report first information when it is in a disconnected state. The above methods will be further explained and illustrated below with specific examples.

[0212] Example 1

[0213] In some embodiments, the random access type can be determined to be the first type of random access, that is, in the 4-step random access process, the step of the terminal reporting the first information may include:

[0214] 1) Msg 1, the terminal sends a random access preamble on the time-frequency resources corresponding to the random access occupancy (RO), where the RO and the preamble are based on contention, that is, they are not dedicated to a certain feature;

[0215] 2) Msg 2, the terminal receives the Random Access Feedback (RAR) and obtains PUSCH resources;

[0216] 3) Msg 3, the terminal sends CSI-related information on the PUSCH resource. The CSI is obtained based on SSB measurement and only includes CQI.

[0217] 4) Msg 4, the terminal receives confirmation of connection establishment completion or contention resolution from the base station.

[0218] Example 2

[0219] In some embodiments, the random access type can be determined to be the first type of random access, that is, in the 4-step random access process, the step of the terminal reporting the first information may include:

[0220] 1) Msg 1, the terminal sends a random access preamble on the time-frequency resources corresponding to the random access opportunity, where RO and preamble are based on contention, that is, not dedicated to a certain feature;

[0221] 2) Msg 2, the terminal receives the Random Access Feedback (RAR) and obtains PUSCH resources;

[0222] 3) Msg 3, the terminal sends CSI-related information on the PUSCH resource. The CSI is obtained based on TRS measurement and only includes CQI.

[0223] 4) Msg 4, the terminal receives confirmation of connection establishment completion or contention resolution from the base station.

[0224] Example 3

[0225] In some embodiments, the random access type can be determined to be the second type of random access, that is, in the two-step random access process, the step of the terminal reporting the first information may include:

[0226] 1) Msg A: The terminal transmits a random access preamble on the time-frequency resources corresponding to the random access opportunity. The RO and preamble are contention-based, meaning they are not dedicated to a specific feature, but the RO and preamble may be the same as or different from those of the first type of random access procedure. Simultaneously, the terminal transmits CSI-related information on the PUSCH. The CSI is obtained based on SSB measurements and only includes CQI.

[0227] 2) Msg B, the terminal receives confirmation of connection establishment completion or contention resolution from the base station.

[0228] Example 4

[0229] In some embodiments, the random access type can be determined to be the second type of random access, that is, in the two-step random access process, the step of the terminal reporting the first information may include:

[0230] 1) Msg A: The terminal transmits a random access preamble on the time-frequency resources corresponding to the random access opportunity. The RO and preamble are contention-based, meaning they are not dedicated to a specific feature, but the RO and preamble may be the same as or different from those of the first type of random access procedure. Simultaneously, the terminal transmits CSI-related information on the PUSCH. The CSI is obtained based on TRS measurements and only includes CQI.

[0231] 2) Msg B, the terminal receives confirmation of connection establishment completion or contention resolution from the base station.

[0232] In some embodiments, the above examples are only some optional ways to implement the terminal reporting the first information, and are not exhaustive. The method of this scheme can use other methods to determine the parameters in the above steps, or use other methods to report. For example, CSI can be changed from only including CQI to including other parameters, such as Rank Indicator (RI), Channel Quality Indicator (CQI), Layer Indicator (LI), CSI-RS Resource Indicator (CRI), and SSB Resource Indicator (SRI). At least one of these parameters can be used; RO or preamble can be replaced with one specific to a certain feature, such as one specifically for early CSI reporting; for the CSI request field of the DCI corresponding to the RAR of Msg 2 used to trigger CSI reporting, the RS corresponding to the CSI can be replaced with CSI-RS, where the CSI request field in the RAR of Msg 2 is also used to indicate the location of the CSI-RS resource and trigger the transmission of the CSI-RS resource, etc.

[0241] In some embodiments, the terminal may send first information to a network device, but is not limited thereto; the terminal may also send first information to other entities.

[0242] Figure 4 is a flowchart illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 4, the present disclosure relates to a communication method for a network device, the method comprising:

[0243] Step 4101: Receive the first information.

[0244] The optional implementation of step 4101 can be found in the optional implementation of step 2101 in Figure 2, step 3103 in Figure 3, and other related parts in the embodiments involved in Figures 2 and 3, which will not be repeated here.

[0245] In some embodiments, the network device receives first information sent by a terminal, but is not limited thereto; it may also receive first information sent by other entities.

[0246] In some embodiments, the network device obtains first information as defined by the protocol.

[0247] In some embodiments, the network device processes information to obtain the first information.

[0248] The following is an exemplary description of the above method.

[0249] The method illustrated in this disclosure relates to a method for early acquisition of CSI, the full content of which is as follows.

[0250] 1. The terminal determines a reference signal resource and obtains CSI-related information based on the reference signal resource. The terminal then transmits the CSI-related information on the PUSCH.

[0251] 2. Based on 1, the PUSCH is the PUSCH resource in Msg A, Msg 3 or the configured CG (configured grant) during the random access process, or the first PUSCH after the random access is completed (contention resolution confirmation information, i.e., Msg4, or Msg B, i.e., the RAR corresponding to Msg A).

[0252] 3. Based on 1 or 2, the reference signal resource is an SSB or a TRS.

[0253] 1) The RS used for CSI measurements is either the broadcast SSB or the CSI-RS resource used for tracking, i.e., TRS.

[0254] 4. Based on 1 or 2, the reference signal resource is a CSI-RS resource.

[0255] 5. Based on any one of 1-3, the CSI request field in the DCI corresponding to the RAR UL grant of Msg 2 in the random access process indicates the request for reporting of CSI-related information.

[0256] 6. Based on 4, determine how to indicate the triggering of CSI-RS resources.

[0257] 1) The CSI request field indication in the DCI (DCI format 0_1 / 0_2 / 0_3, or the CSI request field introduced in DCI format 0_0, which is not present in the traditional DCI format 0_0) corresponding to the RAR UL grant of Msg 2 in the random access procedure.

[0258] a. The standard specifies only one CSI-RS resource configuration. The CSI request field triggers the terminal to receive this type of CSI-RS at the resource location. The QCL source of the CSI-RS can be the same as the SSB corresponding to the access resource.

[0259] b. The standard specifies multiple CSI-RS resource configurations. The CSI request field indicates the codepoint. The terminal determines the triggered CSI-RS resource configuration based on the implicit or explicit mapping relationship (the mapping relationship between the codepoint and multiple CSI-RS resources).

[0260] c. MIB or SIB provides various CSI-RS resource configurations. The CSI request field indicates the codepoint, and the terminal determines the triggered CSI-RS resource configuration based on implicit or explicit mapping relationships.

[0261] d. The PDSCH of Msg 2, Msg 4, or Msg B provides various CSI-RS resource configurations. The CSI request field indicates the codepoint, and the terminal determines the triggered CSI-RS resource configuration based on implicit or explicit mapping relationships.

[0262] e. When a terminal transitions from the RRC connected state to the inactive state, the base station provides various CSI-RS resource configurations in the RRC release information. The CSI request field indicates the codepoint, and the terminal determines the triggered CSI-RS resource configuration based on implicit or explicit mapping relationships.

[0263] 7. Based on 1-6, the random access timing or preamble corresponding to random access is either the first type of random access procedure (4-step random access procedure), or the second type of random access procedure (2-step random access procedure), or the first feature (dedicated to early CSI reporting).

[0264] 8. Based on 1, CSI-related information includes at least one of the following:

[0265] Precoding Matrix Indicator (PMI); Rank Indicator (RI); Channel Quality Indicator (CQI); Layer Indicator (LI); CSI-RS Resource Indicator; SSB Resource Indicator (SRI).

[0266] 9. Based on 1, the terminal is an idle UE or an inactive UE.

[0267] 10. Based on 1-9, the PUSCH resources of Msg A above, the random access RO and preamble are all determined based on broadcast information or system information (MIB or SIB).

[0268] 11. Based on 2, the PUSCH resource of Msg 3 is the DCI indicated by Msg 2RAR UL grant.

[0269] 12. Based on 2, CG PUSCH is configured by the network device when the terminal enters the inactive or idle state from the connected state.

[0270] 13. Based on 2, the first PUSCH after random access is completed can be the PUSCH of the dynamic grant scheduled by the base station DCI, or the configured CG PUSCH.

[0271] The above method will be further explained and illustrated below through specific embodiments.

[0272] Example 1:

[0273] 4-step access process (Type I random access process)

[0274] 1. Msg 1, the terminal sends a random access preamble on the time-frequency resources corresponding to the random access occasion (RO), where the RO and preamble are based on contention, that is, not dedicated to a certain feature.

[0275] 2. Msg 2, the terminal receives the Random Access Feedback (RAR) and obtains PUSCH resources.

[0276] 3. Msg 3, the terminal sends CSI-related information on the PUSCH resource. The CSI is obtained based on SSB measurement and only includes CQI.

[0277] 4. Msg 4, Terminal receives confirmation of connection establishment completion or contention resolution from base station.

[0278] Example 2:

[0279] 4-step access process

[0280] 1. Msg 1, the terminal sends a random access preamble on the time-frequency resources corresponding to the random access occasion (RO), where the RO and preamble are based on contention, that is, not dedicated to a certain feature.

[0281] 2. Msg 2, the terminal receives the Random Access Feedback (RAR) and obtains PUSCH resources.

[0282] 3. Msg 3, the terminal sends CSI-related information on the PUSCH resource. The CSI is obtained based on TRS measurement and only includes CQI.

[0283] 4. Msg 4, Terminal receives confirmation of connection establishment completion or contention resolution from base station.

[0284] Example 3:

[0285] Two-step access procedure (Type II random access procedure)

[0286] 1. Msg A: The terminal transmits a random access preamble on the time-frequency resource corresponding to the random access occasion (RO). The RO and preamble are contention-based, meaning they are not dedicated to a specific feature, but the RO and preamble may be the same as or different from those of the first type of random access procedure. Simultaneously, the terminal transmits CSI-related information on the PUSCH. The CSI is obtained based on SSB measurements and only includes CQI.

[0287] 2. Msg B, the terminal receives confirmation of connection establishment completion or contention resolution from the base station.

[0288] Example 4:

[0289] Two-step access procedure (Type II random access procedure)

[0290] 1. Msg A: The terminal transmits a random access preamble on the time-frequency resource corresponding to the random access occasion (RO). The RO and preamble are contention-based, meaning they are not dedicated to a specific feature, but the RO and preamble may be the same as or different from those of the first type of random access procedure. Simultaneously, the terminal transmits CSI-related information on the PUSCH. The CSI is obtained based on TRS measurements and only includes CQI.

[0291] 2. Msg B, the terminal receives confirmation of connection establishment completion or contention resolution from the base station.

[0292] Other embodiments include replacing CSI with CQI instead of CSI containing only CQI, such as Rank Indicator (RI), Channel Quality Indicator (CQI), Layer Indicator (LI), and CSI-RS Resource Indicator (CRI). It also includes at least one of the following: SSB Resource Indicator (SRI); replacing RO or preamble with one specific to a particular feature, such as one dedicated to early CSI reporting; and replacing the CSI request field in the DCI corresponding to the RAR of Msg 2, which is used to trigger CSI reporting, with the RS corresponding to CSI replaced with CSI-RS. The CSI request field in the RAR of Msg 2 also indicates the location of the CSI-RS resource and triggers the transmission of the CSI-RS resource, etc.

[0293] In summary, the above embodiments of this solution improve throughput by proposing that the terminal obtains and reports CSI during random access, enabling the terminal to transmit data as quickly as possible based on accurate CSI after entering the connected state.
