INFORMATION REPORTING AND RECEIVING METHODS, APPARATUS, TERMINAL, SERVICE NODE, AND STORAGE MEDIUM

TECHNICAL FIELD

The present application relates to wireless communication networks, for example, an information reporting method and apparatus, an information receiving method and apparatus, a terminal, a service node, and a storage medium.

BACKGROUND

In a wireless communication process, the channel state is ever-changing and has a relatively great effect on wireless signals. For example, the quality of a channel can determine the modulation manner of the signals of both sides in the communication and may also affect the contention result during the contention process of establishing a communication. In an application scenario of a non-terrestrial network (NTN), a satellite base station is very far from a ground terminal, resulting in a relatively large transmission delay. For the satellite base station in low Earth orbiting (LEO), the high movement speed may also cause the frequent handoff of terminal access. The lack of an effective information reporting or receiving method in new radio (NR) protocols makes a random access mechanism unable to adapt to a change in channels, greatly reducing the performance of random access in a large-delay and multiple-handoff scenario and resulting in poor reliability.

DETAILED DESCRIPTION

The present application is described hereinafter in conjunction with drawings and embodiments. The embodiments described herein are merely intended to explain and not to limit the present application. Besides, for ease of description, only part, not all, of structures related to the present application are illustrated in the drawings.

In an NTN and multiple-handoff scenario, a satellite base station is very far from a ground terminal, resulting in a large transmission delay. For the satellite base station in LEO, the movement speed up to 7.5 km/s may also cause the frequent handoff of a terminal. The excessively large delay results in a long duration of a random access process and a great effect generated by a change in channels. The frequent handoff results in frequent random access processes. In NR protocols, a CSI reporting mechanism is not added to a random access process. When a service node makes a decision of contention resolution, the transmission performance in the random access process is greatly damaged due to the lack of consideration of channel state information, failing to adapt to the change in channels.

For this embodiment, the CSI reporting mechanism is introduced for random access. The terminal reports the CSI to the service node. According to the CSI reported by the terminal, the service node can select the optimal access terminal among terminals in contention or determine a modulation manner, thus better adapting to a change in wireless channels and improving the performance of random access.

FIG. 1 is a flowchart of an information reporting method according to an embodiment. The information reporting method provided in this embodiment may be applied to a terminal. As shown in FIG. 1, the method includes S110 and S120.

In S110, indication information under a random access mechanism is received.

In an embodiment, the terminal receives the indication information sent by a service node in the random access mechanism. Through a random access response (RAR) message or a downlink broadcast message, the service node may indicate that the terminal reports CSI. In an embodiment, the indication information may be further used for, for example, indicating a parameter of the CSI reported by the terminal and calculating reference signals to be measured by the CSI.

In S120, the channel state information is reported according to the indication information.

In an embodiment, according to the indication information, the terminal obtains the corresponding channel state information by measuring the reference signals and reports the channel state information to the service node. For example, the indication information may indicate that the terminal measures synchronization signal/physical broadcast channel blocks (SSBs) and reports the received power of the optimal reference signal. In this case, when receiving the indication information, the terminal measures the SSBs, determines the received power of the optimal SSB, takes the received power of the optimal SSB as the CSI, and reports the received power of the optimal SSB to the service node. In another example, the indication information may indicate that the terminal measures channel state information reference signals (CSI-RSs) and reports the channel quality indicator (CQI) of the optimal CSI-RS. In this case, when receiving the indication information, the terminal measures the CSI-RSs, determines the CQI of the optimal CSI-RS, takes the CQI of the optimal CSI-RS as the CSI, and reports the CQI of the optimal CSI-RS to the service node. On this basis, the service node can make a random access decision according to the CSI reported by the terminal and send a contention resolution message to the terminal.

In an embodiment, the resource position of the CSI reported by the terminal corresponds to the identifier (ID) of the terminal. In the case where the terminal receives and measures downlink reference signals of multiple base stations, the resource position further corresponds to the ID of a cell.

In an embodiment, the parameter of the reported CSI may be arranged according to an actual situation. For example, the arrangement may be performed according to, for example, high-layer parameter configuration and the number of antenna ports. For example, the indication information may include the indication information of a CQI and is used for indicating that the terminal reports a broadband CQI or a sub-band CQI. In another example, the indication information may include the indication information of a precoding matrix indicator (PMI) and is used for indicating that the terminal reports a broadband PMI or a sub-band PMI in the case of more than one antenna port; in the case where a sub-band PMI is reported and in the case where the number of ports is not two, the indication information is also used for indicating that the terminal reports one broadband PMI (i1) and each sub-band reports one sub-band PMI (i2); in the case of two ports, the indication information is also used for indicating that each sub-band of the terminal reports one sub-sand PMI; and in the case where a PMI is reported, the indication information is also used for indicating that the terminal reports a layer indication (LI) to indicate, for example, the column corresponding to the strongest layer of codewords in a precoding matrix. Each preceding CQI, PMI, LI, or the like is taken as the CSI in reporting so as to help the service node make a decision.

In an embodiment, the indication information is used for indicating that the terminal reports the channel state information through a third message of a first-type random access mechanism. Alternatively, the indication information is used for indicating that the terminal reports the channel state information through an A-type message of a second-type random access mechanism.

In an embodiment, in the case of the first-type random access mechanism, the indication information is a random access response (RAR) message or a downlink broadcast message. In the case of the second-type random access mechanism, the indication information is the downlink broadcast message.

FIG. 2 is a diagram of a first-type random access mechanism according to an embodiment. As shown in FIG. 2, in the first-type random access mechanism, the following is included before the terminal establishes a connection with the service node.

1) The terminal sends a first message (referred to as message1 (msg1)) to the service node. Msg1 includes a random access preamble used for initiating a contention access request to the service node. A contention relationship exists among terminals with the same random access preamble.

2) After receiving msg1, the service node sends a second message (referred to as message2 (msg2)) to the terminal. Msg2 is the RAR message used for responding to the contention access request initiated by the terminal.

3) The terminal sends a third message (referred to as message3 (msg3)) to the service node. Msg3 is used for reporting the CSI according to the indication information of the service node. The indication information may be the RAR message or the downlink broadcast message. The downlink broadcast message is sent by the service node to the terminal before 1).

4) The service node sends a fourth message to the terminal. The fourth message includes the contention resolution message representing the contention resolution solution made by the service node based on the CSI.

In the scenario of the first-type random access mechanism, the indication information is used for indicating that the terminal reports the CSI through msg3.

FIG. 3 is a diagram of a second-type random access mechanism according to an embodiment. As shown in FIG. 3, in the second-type random access mechanism, the following is included before the terminal establishes a connection with the service node.

1) The terminal sends an A-type message (referred to as messageA (msgA)) to the service node according to the indication information, thus initiates the contention access request, and reports the CSI. MsgA includes the random access preamble and the CSI. The indication information is the downlink broadcast message. The downlink broadcast message is sent by the service node to the terminal before 1).

2) After receiving msgA, the service node sends a B-type message (referred to as messageB (msgB)) to the terminal, thus responds to the contention access request initiated by the terminal, and indicates the contention resolution solution according to the CSI. MsgB includes the RAR message and the contention resolution message.

In the scenario of the second-type random access mechanism, the indication information is used for indicating that the terminal reports the CSI through msgA.

In an embodiment, the indication information includes at least one of the first indication information used for indicating a parameter included in the channel state information reported by the terminal, the second indication information used for indicating reference signals to be measured when the terminal calculates the channel state information, and the third indication information used for indicating a reporting operation performed by the terminal to the channel state information. The reporting operation includes to report and not to report.

In this embodiment, the first indication information may be used for indicating the parameter included in the CSI reported by the terminal, for example, the index of the optimal reference signal, the reference signal received power (RSRP) of the optimal reference signal, the CQI of the optimal reference signal, the PMI of the optimal reference signal, and the rank indicator (RI) of the optimal reference signal. The second indication information may be used for indicating that the terminal calculates the CSI by measuring the SSBs or the CSI-RSs. The third indication information is used for indicating whether the terminal needs to report the CSI.

In an embodiment, in the case where the indication information does not include one item of information, the corresponding indication content may be determined according to a preset rule. For example, in the case where the indication information does not include the first indication information, which parameters to be included in the reported CSI is indicated between the terminal and the service node through pre-agreement, through a protocol provision, or through the notification by another signaling. The terminal reports these parameters in the process of reporting the CSI.

In an embodiment, in the case where the indication information does not include the second indication information and in the case of the first-type random access mechanism, the reference signals to be measured when the terminal calculates the CSI are reference signals corresponding to a resource occupied by the first message of the first-type random access mechanism. Alternatively, in the case where the indication information does not include the second indication information and in the case of the second-type random access mechanism, the reference signals to be measured when the terminal calculates the CSI are reference signals corresponding to resources occupied by the A-type message of the second-type random access mechanism. The reference signals include at least one of the SSBs or the CSI-RSs.

In this embodiment, as for the first-type random access mechanism, in the case where the indication information does not include the second indication information, the terminal obtains the CSI by measuring the reference signals corresponding to the resource occupied by the first message. The resource occupied by the first message is a physical random access channel (PRACH). As for the second-type random access mechanism, in the case where the indication information does not include the second indication information, the terminal obtains the CSI by measuring the reference signals corresponding to the resources occupied by the A-type message. The resources occupied by the A-type message are the PRACH and a physical uplink shared channel (PUSCH).

In an embodiment, the channel state information is obtained by measuring the reference signals. The reference signals include at least one of the SSBs or the CSI-RSs.

In an embodiment, the parameter of the channel state information includes at least one of the index of the optimal reference signal, the RSRP of the optimal reference signal, the CQI of the optimal reference signal, the RI of the optimal reference signal, or the PMI of the optimal reference signal.

In an embodiment, the parameter of the channel state information includes the index of the optimal reference signal. Alternatively, in the case where the index of the optimal reference signal is consistent with the index of a reference signal corresponding to a resource that is occupied by the first message of the first-type random access mechanism or the A-type message of the second-type random access mechanism, the parameter of the channel state information does not include the index of the optimal reference signal, where the reference signal corresponding to the resource is used for transmitting the first message of the first-type random access mechanism or the A-type message of the second-type random access mechanism. In the case where the index of the optimal reference signal is inconsistent with the index of the reference signal corresponding to a resource that is occupied by the first message of the first-type random access mechanism or the A-type message of the second-type random access mechanism, the parameter of the channel state information includes the index of the optimal reference signal, where the reference signal corresponding to the resource is used for transmitting the first message of the first-type random access mechanism or the A-type message of the second-type random access mechanism.

In an embodiment, in the case of one reference signal antenna port, the parameter of the channel state information does not include the PMI or the RI. Alternatively, in the case of more than one reference signal antenna port, the parameter of the channel state information includes at least one of the index of the optimal reference signal, the reference signal received power (RSRP) of the optimal reference signal, the channel quality indicator (CQI) of the optimal reference signal, the rank indicator (RI) of the optimal reference signal, or the precoding matrix indicator (PMI) of the optimal reference signal.

In this embodiment, in the case of one reference signal antenna port, it is unnecessary to distinguish a rank from a precoding matrix. Accordingly, the parameter of the reported CSI may not include the PMI or the RI, but includes at least one of the index of the optimal reference signal, the RSRP of the optimal reference signal, or the CQI of the optimal reference signal. Alternatively, in the case of more than one reference signal antenna port, the parameter of the CSI includes at least one of the index of the optimal reference signal, the RSRP of the optimal reference signal, the CQI of the optimal reference signal, the RI of the optimal reference signal, or the PMI of the optimal reference signal.

In an embodiment, the optimal reference signal is the reference signal with the largest measurement power or the reference signal with the largest CQI.

In this embodiment, the reference signals may be the SSBs and the CSI-RSs. The reference signals are measured. The reference signal with the largest received power is taken as the optimal reference signal. Alternatively, the reference signal with the largest CQI is taken as the optimal reference signal. Moreover, the CSI of the optimal reference signal is reported. The CSI may include at least one of the index of the optimal reference signal, the RSRP of the optimal reference signal, the CQI of the optimal reference signal, the RI of the optimal reference signal, or the PMI of the optimal reference signal.

In an embodiment, after reporting the channel state information according to the indication information, the method further includes receiving the contention resolution message generated by the service node according to the channel state information and, in the case where the terminal ID in the contention resolution message is consistent with the ID of the terminal reporting the CSI, establishing a connection with the service node.

For example, in an embodiment, the random access is initial random access. The indication information is the downlink broadcast signal used for indicating that the terminal reports the CSI through msg3 of the first-type random access mechanism. The parameter of the reported CSI includes the index of the optimal SSB and the RSRP of the optimal SSB. Moreover, the RSRP is obtained by measuring the SSBs.

In this embodiment, after receiving the downlink broadcast signal, the terminal searches in downlink SSB beams for a beam whose received power exceeds the preset threshold. It is supposed that a total of K downlink SSB beams (referred to as B₁, . . . , B_K) exist and that the searched beam whose received power exceeds the preset threshold is B₁. In this case, the terminal sends msg1 in the uplink beam corresponding to B₁. Msg1 includes the random access preamble. After receiving msg1, the service node sends the RAR message in a physical downlink shared channel (PDSCH). After receiving the RAR message, the terminal measures all the downlink SSB beams according to the indication of the downlink broadcast signal, determines to receive the SSB beam (referred to as B_K) with the largest received power, and reports the CSI through sending msg3 to the service node. Whether the SSB beam (B_K) with the largest received power is consistent with the SSB beam (B₁) corresponding to the resource occupied by sending msg1 or not, the parameter of the reported CSI includes the index of the optimal SSB and the RSRP of the optimal SSB. After receiving msg3, the service node makes a decision based on the CSI reported by the terminal and sends the contention resolution message (that is, message4 (msg4)). After the terminal receives msg4, the contention succeeds when the terminal ID included in msg4 is consistent with the ID of the terminal sending msg3; in this case, the terminal establishes a connection with the service node, and the random access process ends. When the terminal ID included in msg4 is inconsistent with the ID of the terminal sending msg3, the contention fails and the random access is reinitiated.

For example, in an embodiment, the random access is initial random access. The indication information is the downlink broadcast signal used for indicating that the terminal reports the CSI through msg3 of the first-type random access mechanism. The parameter of the reported CSI includes the index of the optimal SSB and the RSRP of the optimal SSB or includes only the RSRP of the optimal SSB. Moreover, the RSRP is obtained by measuring the SSBs.

In this embodiment, after receiving the downlink broadcast signal, the terminal searches in downlink SSB beams for a beam whose received power exceeds the preset threshold. It is supposed that a total of K downlink SSB beams (referred to as B₁, . . . , B_K) exist and that the searched beam whose received power exceeds the preset threshold is B₁. In this case, the terminal sends msg1 in the uplink beam corresponding to B₁. Msg1 includes the random access preamble. After receiving msg1, the service node sends the RAR message in the PDSCH. After receiving the RAR message, the terminal measures all the downlink SSB beams according to the indication of the downlink broadcast signal, determines to receive the SSB beam (referred to as B_K) with the largest received power, and reports the CSI through sending msg3 to the service node. In the preceding case where B_Kis consistent with B₁(that is, k=1), the reported CSI may include only the RSRP of B_Kand does not include the index of B_K, indicating that B₁is the optimal SSB with the largest received power. In the preceding case where B_Kis inconsistent with B₁(that is, k∈{1, 2, . . . , K},k≠1), the reported CSI may include the index of B_Kand the RSRP of B_K. After receiving msg3, the service node makes a decision based on the CSI reported by the terminal and sends the contention resolution message msg4. After the terminal receives msg4, the contention succeeds when the terminal ID included in msg4 is consistent with the ID of the terminal sending msg3; in this case, the terminal establishes a connection with the service node, and the random access process ends. When the terminal ID included in msg4 is inconsistent with the ID of the terminal sending msg3, the contention fails and the random access is reinitiated.

For example, in an embodiment, the random access is initial random access. The indication information is the RAR message used for indicating that the terminal reports the CSI through msg3 of the first-type random access mechanism. The parameter of the reported CSI includes the RSRP of the optimal SSB. Moreover, the RSRP is obtained by measuring the SSBs.

After receiving the RAR message, the terminal measures all the downlink SSB beams according to the indication of the RAR message, determines to receive the SSB beam (referred to as B_K) with the largest received power, and reports the CSI through sending msg3 to the service node. Whether the SSB beam (B_K) with the largest received power is consistent with the SSB beam (B₁) corresponding to the resource occupied by sending msg1 or not, the parameter of the reported CSI includes the index of the optimal SSB and the RSRP of the optimal SSB. After receiving msg3, the service node makes a decision based on the CSI reported by the terminal and sends the contention resolution message msg4. After the terminal receives msg4, the contention succeeds when the terminal ID included in msg4 is consistent with the ID of the terminal sending msg3; in this case, the terminal establishes a connection with the service node, and the random access process ends. When the terminal ID included in msg4 is inconsistent with the ID of the terminal sending msg3, the contention fails and the random access is reinitiated.

In the preceding case where B_Kis consistent with B₁(that is, k=1), the reported CSI may include only the RSRP of B_Kand does not include the index of B_K, indicating that B₁is the optimal SSB with the largest received power. In the preceding case where B_Kis inconsistent with B₁(that is, k∈{1, 2, . . . , K},k≠1) the reported CSI may include the index of B_Kand the RSRP of B_K. After receiving msg3, the service node makes a decision based on the CSI reported by the terminal and sends the contention resolution message msg4. After the terminal receives msg4, the contention succeeds when the terminal ID included in msg4 is consistent with the ID of the terminal sending msg3; in this case, the terminal establishes a connection with the service node, and the random access process ends. When the terminal ID included in msg4 is inconsistent with the ID of the terminal sending msg3, the contention fails and the random access is reinitiated.

For example, in an embodiment, the random access is non-initial random access. The indication information is a downlink broadcast signal used for indicating that the terminal reports the CSI through msg3 of the first-type random access mechanism. The parameter of the reported CSI includes the index of the optimal SSB or the index of the optimal CSI-RS (the index of the optimal CSI-RS is also referred to as the CSI-RS resource indicator (CRI)) and further includes the RSRP of the optimal SSB or the RSRP of the optimal CSI-RS. Moreover, the RSRP is obtained by measuring the SSBs or the CSI-RSs.

In this embodiment, after receiving the downlink broadcast signal, the terminal searches in reference signal beams (SSB beams or CSI-RS beams) for a beam whose received power exceeds the preset threshold. It is supposed that a total of K reference signal beams (referred to as B₁, . . . , B_K) exist and that the searched beam whose received power exceeds the preset threshold is B₁. In this case, the terminal sends msg1 in the uplink beam corresponding to B₁. Msg1 includes the random access preamble. After receiving msg1, the service node sends the RAR message in the PDSCH. After receiving the RAR message, the terminal measures all the downlink SSB beams according to the indication of the downlink broadcast signal, determines to receive the reference signal beam (referred to as B_K) with the largest received power, and reports the CSI through sending msg3 to the service node. Whether B_Kis consistent with B₁or not, the parameter of the reported CSI includes the index of the optimal reference signal and the RSRP of the optimal reference signal. When the RSRP is obtained by measuring the SSBs, the index of the optimal reference signal is the index of the optimal SSB. When the RSRP is obtained by measuring the CSI-RSs, the index of the optimal reference signal is the CRI. After receiving msg3, the service node makes a decision based on the CSI reported by the terminal and sends the contention resolution message msg4. After the terminal receives msg4, the contention succeeds when the terminal ID included in msg4 is consistent with the ID of the terminal sending msg3; in this case, the terminal establishes a connection with the service node, and the random access process ends. When the terminal ID included in msg4 is inconsistent with the ID of the terminal sending msg3, the contention fails and the random access is reinitiated.

For example, in an embodiment, the random access is non-initial random access. The indication information is the downlink broadcast signal used for indicating that the terminal reports the CSI through msg3 of the first-type random access mechanism. The parameter of the reported CSI includes the RSRP of the optimal SSB or the RSRP of the optimal CSI-RS and may further include the index of the optimal SSB or the index of the optimal CSI-RS (the index of the optimal CSI-RS is also referred to as the CSI-RS resource indicator (CRI)). Moreover, the RSRP is obtained by measuring the SSBs or the CSI-RSs.

In this embodiment, after receiving the downlink broadcast signal, the terminal searches in reference signal beams (SSB beams or CSI-RS beams) for a beam whose received power exceeds the preset threshold.

In the preceding case where B_Kis consistent with B₁(that is, k=1), the reported CSI may include only the RSRP of B_Kand does not include the index of B_K, indicating that B₁is the optimal reference signal with the largest received power. In the preceding case where B_Kis inconsistent with B₁(that is k∈{1, 2, . . . , K},k≠1), the reported CSI may include the index of B_Kand the RSRP of B_K. When the RSRP is obtained by measuring the SSBs, the index of the optimal reference signal is the index of the optimal SSB. When the RSRP is obtained by measuring the CSI-RSs, the index of the optimal reference signal is the CRI. After receiving msg3, the service node makes a decision based on the CSI reported by the terminal and sends the contention resolution message msg4. After the terminal receives msg4, the contention succeeds when the terminal ID included in msg4 is consistent with the ID of the terminal sending msg3; in this case, the terminal establishes a connection with the service node, and the random access process ends.

Whether B_Kis consistent with B₁or not, the parameter of the reported CSI includes the index of the optimal reference signal and the RSRP of the optimal reference signal. When the RSRP is obtained by measuring the SSBs, the index of the optimal reference signal is the index of the optimal SSB. When the RSRP is obtained by measuring the CSI-RSs, the index of the optimal reference signal is the CRI.

After receiving the RAR message, the terminal measures all the downlink SSB beams according to the indication of the RAR message, determines to receive the reference signal beam (referred to as B_K) with the largest received power, and reports the CSI through sending msg3 to the service node. In the preceding case where B_Kis consistent with B₁(that is, k=1), the reported CSI may include only the RSRP of B_Kand does not include the index of B_K, indicating that B₁is the optimal reference signal with the largest received power. In the preceding case where B_Kis inconsistent with B₁(that is, k∈{1, 2, . . . , K},k≠1), the reported CSI may include the index of B_Kand the RSRP of B_K. When the RSRP is obtained by measuring the SSBs, the index of the optimal reference signal is the index of the optimal SSB. When the RSRP is obtained by measuring the CSI-RSs, the index of the optimal reference signal is the CRI. After receiving msg3, the service node makes a decision based on the CSI reported by the terminal and sends the contention resolution message msg4. After the terminal receives msg4, the contention succeeds when the terminal ID included in msg4 is consistent with the ID of the terminal sending msg3; in this case, the terminal establishes a connection with the service node, and the random access process ends. When the terminal ID included in msg4 is inconsistent with the ID of the terminal sending msg3, the contention fails and the random access is reinitiated.

For example, in an embodiment, the indication information is the downlink broadcast signal used for indicating that the terminal reports the CSI through msg3 of the first-type random access mechanism. The service node has one antenna port. The parameter of the reported CSI includes the CQI of the optimal CSI-RS.

The parameter of the reported CSI includes the RSRP of the optimal reference signal and the index of the optimal reference signal. When the random access is initial random access, the RSRP can be obtained only by measuring the SSBs. When the random access is non-initial random access, the RSRP can be obtained by measuring the SSBs or the CSI-RSs.

In this embodiment, after receiving the downlink broadcast signal, the terminal measures the received power of all the reference signals according to the indication of the downlink broadcast signal and selects the beam (which may not be the beam with the largest received power) corresponding to the earliest RACH occasion (RO) among beams whose received power exceeds the threshold value. It is supposed that the beam is B₁(and that a total of K beams (referred to as B₁, . . . , B_K) exist). MsgA is sent in the uplink beam corresponding to B₁. MsgA includes the random access preamble and the CSI. Whether the beam with the largest received power is B₁or not, the parameter of the reported CSI includes the RSRP of the optimal reference signal and the index of the optimal reference signal.

When the terminal ID included in msgB is inconsistent with the ID of the terminal sending msgA, the contention fails and the random access is reinitiated.

In an embodiment, in the case where the beam with the largest received power is consistent with B₁, the parameter of the reported CSI may include or not include the index of the optimal reference signal.

For example, in one embodiment, the indication information is a broadcast signal or RAR message used for indicating that the terminal reports the CSI through msg3 of the first-type random access mechanism. Moreover, the CSI is obtained by measuring reference signals of different cells (including the cell to which this base station belongs). The reported parameter includes the index of the cell and further includes at least one of the index of the optimal reference signal, the RSRP of the optimal reference signal, the CQI of the optimal reference signal, the RI of the optimal reference signal, or the PMI of the optimal reference signal.

In this embodiment, after receiving the downlink broadcast signal, the terminal sends msg1 in the corresponding PRACH. Msg1 includes the random access preamble. After receiving msg1 sent by the terminal, the service node sends the RAR message in the PDSCH. After receiving the RAR message, the terminal measures the CSI-RSs according to the indication of the downlink broadcast message or the RAR message and reports the CSI through sending msg3 to the service node. The parameter of the reported CSI includes the index of the cell and further includes at least one of the index of the optimal reference signal, the RSRP of the optimal reference signal, the CQI of the optimal reference signal, the RI of the optimal reference signal, or the PMI of the optimal reference signal. After receiving msg3, the service node makes a decision based on the CSI reported by the terminal and sends the contention resolution message msg4. When the index of the cell in the CSI is consistent with the index of the current cell, the current service node (which is supposed to be base station 1) sends the contention resolution message. After the terminal receives msg4, the contention succeeds when the terminal ID included in msg4 is consistent with the ID of the terminal sending msg3; in this case, the terminal establishes a connection with base station 1, and the random access process ends. When the terminal ID included in msg4 is inconsistent with the ID of the terminal sending msg3, the contention fails and the random access is reinitiated. When the index of the cell (which is supposed to be base station 2) in the CSI is inconsistent with the index of the current cell, the current service node (which is supposed to be base station 1) sends the contention resolution message. After the terminal receives msg4, the contention succeeds when the terminal ID included in msg4 is consistent with the ID of the terminal sending msg3; in this case, the terminal establishes a connection with base station 1. When the terminal ID included in msg4 is inconsistent with the ID of the terminal sending msg3, the contention fails and the random access is reinitiated. After the terminal establishes a connection with base station 1, base station 1 sends a scheduling message to tell the terminal to monitor the signal sent by the service node (base station 2) corresponding to the index of the cell in the CSI. The configuration information of the scheduling message is consistent with the configuration information of the service node (base station 2) corresponding to the index of the cell in the CSI; that is, the terminal is to establish a connection with base station 2.

For example, in one embodiment, the indication information is the broadcast signal used for indicating that the terminal reports the CSI through msgA of the second-type random access mechanism. Moreover, the CSI is obtained by measuring reference signals of different cells (including the cell to which this base station belongs). The reported parameter includes the index of the cell and further includes at least one of the index of the optimal reference signal, the RSRP of the optimal reference signal, the CQI of the optimal reference signal, the RI of the optimal reference signal, or the PMI of the optimal reference signal.

In this embodiment, after receiving the downlink broadcast signal, the terminal measures the CSI-RSs according to the indication of the downlink broadcast message and reports the CSI through sending msgA to the service node. MsgA includes the random access preamble and the CSI. The parameter of the reported CSI includes the index of the cell and further includes at least one of the index of the optimal reference signal, the RSRP of the optimal reference signal, the CQI of the optimal reference signal, the RI of the optimal reference signal, or the PMI of the optimal reference signal. After receiving msgA, the service node makes a decision based on the CSI reported by the terminal and sends msgB. MsgB includes the contention resolution message and the RAR message. When the index of the cell in the CSI is consistent with the index of the current cell, the current service node (which is supposed to be base station 1) sends the contention resolution message. After the terminal receives msgB, the contention succeeds when the terminal ID included in msgB is consistent with the ID of the terminal sending msgA; in this case, the terminal establishes a connection with base station 1, and the random access process ends. When the terminal ID included in msgB is inconsistent with the ID of the terminal sending msgA, the contention fails and the random access is reinitiated. When the index of the cell (which is supposed to be base station 2) in the CSI is inconsistent with the index of the current cell, the current service node (which is supposed to be base station 1) sends the contention resolution message. After the terminal receives msgB, the contention succeeds when the terminal ID included in msgB is consistent with the ID of the terminal sending msgA; in this case, the terminal establishes a connection with base station 1, and the random access process ends. When the terminal ID included in msgB is inconsistent with the ID of the terminal sending msgA, the contention fails and the random access is reinitiated. After the terminal establishes a connection with base station 1, the terminal sends a scheduling message to tell the terminal to monitor the signal sent by the base station (base station 2) corresponding to the index of the cell in the CSI. The configuration information of the scheduling message is consistent with the configuration information of the base station (base station 2) corresponding to the index of the cell in the CSI; that is, the terminal is to establish a connection with base station 2.

For the information reporting method of this embodiment, the CSI reporting mechanism is introduced for random access. The terminal reports the CSI to the service node.
