[0002] The distributed ultra-large-scale antenna system in the sixth-generation mobile communication technology (6G) network has the remarkable characteristics of more antennas, wider geographical distribution, and deeper intelligent synergy. The distributed ultra-large-scale antenna system consists of a large number of sites distributed in different geographical locations to form a distributed collaborative cluster. The collaborative multi-sites interact with each other to schedule information and collaborate to complete resource scheduling, joint data transmission and other processes. Through intelligent interaction and intelligent collaboration, on the one hand, interference is effectively eliminated and the signal reception quality is enhanced; on the other hand, coverage is effectively enhanced and the user's sense of boundary is eliminated.

[0058] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0059] In related technologies, if a terminal wants to obtain distributed cooperative transmission, it needs to access the network first, and then it can carry out cooperative transmission on the service channel. If it is in a high-low frequency cooperative network, this process is more lengthy, and the terminal needs to access the network once at the low frequency, and then it needs to access the network once at the high frequency before it can start cooperative transmission.

[0060] In view of the above problems, the synchronization signals in the system (specifically, synchronization signal blocks (SSBs)) can be divided into two categories: one is the ordinary synchronization signal (i.e., non-cooperative synchronization signal), and each TRP independently sends the synchronization signal at the position of this type of synchronization signal; the other is the cooperative synchronization signal, and different TRPs can cooperate to send the synchronization signal at the position of this type of synchronization signal. Figure 1 As shown, the terminal can measure the information of the cooperative cell in the synchronization phase, so as to start cooperative transmission in the access phase, such as Figure 1 As shown, there is no need to perform multiple measurements before accessing the network, thereby reducing latency and increasing the rate or reliability of the access process.

[0061] In the above situation, when the terminal searches for a cell, it will see two types of synchronization signals, one is a common synchronization signal, and the other is a collaborative synchronization signal. How the terminal selects a network and quickly accesses the network under this network architecture (which can be called a hybrid network) is an urgent problem to be solved.

[0062] In a distributed system, at the transmission position of the coordinated synchronization signal, multiple TRPs transmit the coordinated synchronization signal at the position in a single frequency network (SFN). When searching for synchronization signals, the terminal may search for multiple synchronization signals including coordinated and non-cooperative synchronization signals. Since the coordinated synchronization signal is transmitted using SFN, when the terminal receives such synchronization signals, the corresponding reference signal received power (RSRP) is likely to be higher than the RSRP of the non-cooperative synchronization signal. When the terminal performs random access in the coordinated cell, since the RSRP of the coordinated synchronization signal is higher, when performing random access power control, the terminal will use this higher RSRP for path loss estimation, resulting in lower power for sending the physical random access channel (PRACH) (i.e., sending the preamble sequence (English expression: Preamble)). Under normal circumstances, the purpose of uplink power control for uplink signals is to reduce the interference of uplink signals to adjacent cells. However, in a cooperative system, at least on this cooperative PRACH resource, multiple cells can perform joint reception, so the problem of inter-cell interference is not serious. Moreover, if the receiving power on this resource is too low, it may cause the terminal signal to be submerged, increasing the complexity of joint reception. In addition to affecting the uplink reception performance, the preamble sequence may be resent, which may also cause excessive access delay.

[0063] Based on this, in various embodiments of the present application, the network side instructs the terminal to determine the random access sequence transmission power in a collaborative manner or a non-collaborative manner, thereby ensuring the performance of uplink access and reducing the access delay.

[0064] The present application embodiment provides an information configuration method, which is applied to a network device (specifically a base station), such as Figure 2 As shown, the method includes:

[0065] Step 201: configuring first information through the MIB or SIB corresponding to the first synchronization signal; the first information indicates a first offset value;

[0066] Step 202: configure or not configure second information to indicate whether the first offset value is used to calculate the random access sequence transmit power.

[0067] In step 202, second information is configured or not configured so that the terminal can determine whether the first offset value is used to calculate the random access sequence transmission power.

[0068] Among them, in steps 201 and 202, it can be understood that the first information is configured to the terminal, and the second information is configured or not configured.

[0069] In actual application, the terminal may be referred to as user equipment (UE) or as a user.

[0070] The network device can configure the terminal to receive the first type of synchronization signal and / or the second type of synchronization signal; the first type of synchronization signal includes a collaborative synchronization signal; correspondingly, the second type of synchronization signal includes a non-collaborative synchronization signal. For the collaborative synchronization signal, multiple TRPs collaboratively send the synchronization signal at the corresponding position; correspondingly, for the non-collaborative synchronization signal, each TRP independently sends the synchronization signal at the corresponding position.

[0071] Here, in actual application, the synchronization signal may specifically be SSB, and the offset value may also be referred to as an offset.

[0072] The first synchronization signal comprises a cooperative synchronization signal.

[0073] The size of the first offset value is related to the number of TRPs at the transmission position of the current collaborative synchronization signal. The more the number of collaborative TRPs, the larger the first offset value. For example, the size of the first offset value can be configured to be proportional to the number of TRPs; illustratively, there are two collaborative synchronization signals, the number of collaborative TRPs on the first collaborative synchronization signal is 2, and the number of collaborative TRPs on the second collaborative synchronization signal is 4, then the offset value corresponding to the first collaborative synchronization signal can be configured to 3dB; the offset value corresponding to the second collaborative synchronization signal can be configured to 6dB.

[0074] As mentioned above, when searching for synchronization signals, the terminal may search for multiple synchronization signals including cooperative and non-cooperative synchronization signals. Since cooperative synchronization signals are transmitted using SFN, when the terminal receives such synchronization signals, the corresponding RSRP is likely to be higher than the RSRP of non-cooperative synchronization signals, which may cause a large number of terminals to want to access the network through cooperative synchronization signals. On the other hand, although the RSRP corresponding to the cooperative synchronization signal is often higher than the RSRP of the non-cooperative synchronization signal when the terminal receives the synchronization signal, if the terminal is only close to a few of the cooperative nodes and far away from other nodes in the cooperative nodes, the actual cooperative effect cannot be guaranteed at this time, so it is not desired that such terminals access the network in a cooperative manner.

[0075] Therefore, when the terminal selects the synchronization signal for access, it needs to distinguish between the cell selection or cell reselection judgment criteria, that is, for the collaborative synchronization signal, the corresponding RSRP must be high enough to be selected for access. For example, if there are 2 TRPs cooperating at the transmission position of the current collaborative synchronization signal, then the RSRP of the collaborative synchronization signal needs to be 3dB higher than the threshold for normal access to the non-collaborative cell, and the terminal can access the network on this collaborative synchronization signal. Therefore, according to the number of collaborative TRPs at the transmission position of the collaborative synchronization signal, the terminal can be notified of the corresponding threshold, so that the terminal can select the cell, thereby realizing the allocation of initial access resources between collaborative and non-collaborative cells, ensuring the user allocation ratio of collaborative cells and non-collaborative cells, and avoiding concentrated access to collaborative cells due to excessively strong signals.

[0076] Based on this, in one embodiment, the first information may at least indicate the offset of the cell selection reception level value and / or the cell selection quality value corresponding to the first synchronization signal when the terminal calculates the cell selection criteria. In this way, after receiving the first information, the terminal may use the first information to determine the amount of reduction in the cell selection reception level value and / or the cell selection quality value corresponding to the first synchronization signal.

[0077] That is, the first offset value is configured in the system message, and the terminal needs to consider the offset value when calculating the access criterion.

[0078] In actual application, the identifiers (such as IDs) corresponding to the cooperative synchronization signal and the non-cooperative synchronization signal are different.

[0079] In actual application, since an offset value is introduced considering the collaboration between multiple TRPs, the first offset value can be a relative value, which can be used to determine both the sending power of the random access sequence and the amount of reduction in the cell selection reception level value and / or cell selection quality value corresponding to the first synchronization signal.

[0080] In actual application, in step 202, configuring or not configuring the second information can play two different roles; specifically,

[0081] The first function is a direct confirmation (expressed in English as compliant), that is, if the second information is configured, it can be directly determined that the first offset value is used to calculate the random access sequence transmission power. Correspondingly, if the second information is not configured, it can be directly determined that the first offset value is not used to calculate the random access sequence transmission power.

[0082] Based on this, in one embodiment, second information is configured, where the first information indicates an offset when calculating the random access sequence transmission power.

[0083] The second function is an indirect confirmation function, that is, if the second information is configured, it is indirectly determined that the first offset value is not used to calculate the random access sequence transmit power; accordingly, if the second information is not configured, it is indirectly determined that the first offset value is used to calculate the random access sequence transmit power.

[0084] In this case, the network device may configure the second information to the terminal as needed, or not configure the second information to the terminal. For example, it may determine whether to configure the second information to the terminal based on the number of coordinated TRPs when PRACH is actually received. Exemplarily, if the number of coordinated TRPs at the transmission position of the first synchronization signal is the same as the number of coordinated TRPs when PRACH is actually received, the second information may not be configured to the terminal, so that the terminal uses the first offset value to calculate the random access sequence transmission power (i.e., determines the random access sequence transmission power using the first offset value); if the number of coordinated TRPs at the transmission position of the first synchronization signal is less than the number of coordinated TRPs when PRACH is actually received, the second information may be configured to the terminal.

[0085] In one embodiment, when the second information indicates a second offset value, the second offset value is different from the first offset value; the second offset value is used to determine an increase amount when calculating the random access sequence transmission power.

[0086] Here, in actual application, the size of the second offset value is related to the number of coordinated TRPs when actually receiving PRACH. Of course, the more coordinated TRPs there are, the larger the second offset value is. Exemplarily, the number of coordinated TRPs on the first synchronization signal is 4, and the first offset value can be configured as 6dB, but when actually receiving PRACH, only 2 TRPs are used for coordination, then the second offset value is configured as 3dB, and if only 1 TRP is used to receive PRACH, then the second offset value is configured as 0dB.

[0087] In actual application, the network device may instruct the terminal to calculate the random access sequence transmission power using other methods. For example, the network device may be configured according to the situation of the TRP that actually receives the PRACH. Exemplarily, if there is only one TRP receiving PRACH, the terminal is instructed to use the resources of a synchronization signal sent by this TRP to determine the random access sequence transmission power; wherein, this synchronization signal may be the first synchronization signal, or other synchronization signals different from the first synchronization signal; if there are two TRPs receiving PRACH, the terminal may be instructed to use the resources of any one of the synchronization signals sent by these two TRPs to determine the random access sequence transmission power; wherein, any one of the synchronization signals sent by these two TRPs may be the first synchronization signal, or other synchronization signals different from the first synchronization signal.

[0088] Based on this, in one embodiment, the second information indicates that the random access sequence transmission power is determined based on the resources of the second synchronization signal; and the identifiers of the first synchronization signal and the second synchronization signal are the same or different.

[0089] Here, in actual application, the second information may include a synchronization signal identifier and a cell identifier, so as to instruct the terminal to perform path loss calculation based on the newly allocated second synchronization signal, thereby determining the random access sequence transmission power.

[0090] The random access sequence transmit power may be referred to as PRACH transmit power.

[0091] From the above description, it can be seen that the solution provided in the embodiment of the present application ensures the power of PRACH reception for the collaborative network access method. Since this access method does not have the problem of interference between cells, the PRACH transmission power can be increased by configuration, which can speed up the access speed and reduce the access delay.

[0092] In one embodiment, the network device may configure the second information to the terminal through the SIB, so that the terminal can obtain the second information in a timely manner.

[0093] Accordingly, the embodiment of the present application also provides an information configuration method, which is applied to a terminal, such as Figure 3 As shown, the method includes:

[0094] Step 301: receiving first information through the MIB or SIB corresponding to the first synchronization signal; the first information indicates a first offset value;

[0095] Step 302: Determine whether the first offset value is used to calculate the random access sequence transmission power according to the situation of receiving the second information.

[0096] The situation of receiving the second information includes receiving the second information or not receiving the second information.

[0097] As mentioned above, configuring or not configuring the second information can play two different roles. Under different roles, the process of determining whether the first offset value is used to calculate the random access sequence transmit power is different; specifically,

[0098] When the role of configuring or not configuring the second information is direct confirmation, when the second information is not received, the terminal determines that the first offset value is not used to calculate the random access sequence transmit power; when the second information is received, the terminal determines that the first offset value is used to calculate the random access sequence transmit power, at this time, the first information indicates the offset when calculating the random access sequence transmit power; the terminal uses the first information to determine the amount to increase when calculating the random access sequence transmit power.

[0099] When the role of configuring or not configuring the second information is an indirect confirmation role, when the terminal receives the second information, it is determined that the first offset value is not used to calculate the random access sequence transmission power; when the terminal does not receive the second information, it is determined that the first offset value is used to calculate the random access sequence transmission power.

[0100] In one embodiment, the first at least indicates an offset of a cell selection reception level value and / or a cell selection quality value corresponding to the first synchronization signal when the terminal calculates a cell selection criterion;

[0101] The terminal uses the first information to determine a reduction in a cell selection reception level value and / or a cell selection quality value corresponding to the first synchronization signal.

[0102] Specifically, the terminal calculates the cell selection criterion using the following formula:

[0103] Srxlev=Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Qoffset temp -δ1 (1)

[0104] Squal=Q qualmeas –(Q qualmin +Q qualminoffset )-Qoffset temp -δ1 (2)

[0105] Among them, Srxlev represents the cell selection reception level value; Q rxlevmeas Indicates the reception level of the measured cell; Q rxlevmin Indicates the minimum required reception level of the cell; Q rxlevminoffset Indicates that during Srxlev evaluation, when normally residing in a visited public land mobile network (VPLMN), the Q rxlevmin The offset value considered above; P compensation Indicates the maximum power compensation value; Qoffset tempIndicates the currently configured cell offset value; Squal indicates the cell selection quality value; Q qualmeas Indicates the measured cell quality value; Q qualmin Indicates the minimum required quality value of the cell; Q qualminoffset Indicates that during the Squal evaluation, when normally residing in the VPLMN, the Q qualmin The offset value considered above; δ1 represents the first offset value.

[0106] It can be seen from the above formula that the first offset value is at least used to calculate the reduction amount of the reference signal quality value obtained on the first synchronization signal.

[0107] In the case where the role of configuring or not configuring the second information is an indirect confirmation role, when the terminal does not receive the second information, the first information indicates the offset when calculating the random access sequence transmission power; at this time, the terminal also uses the first information to determine the amount to increase when calculating the random access sequence transmission power.

[0108] Specifically, the terminal calculates the random access sequence transmit power using the following formula:

[0109] P PRACHb,f,c (i) = min{P cmax,f,c (i),P PRACH,target,f,c +PL b,f,c +δ1} (3)

[0110] Among them, P PRACHb,f,c (i) represents the random access sequence transmission power at transmission opportunity i; P cmax,f,c (i) represents the maximum output power configured by the terminal on transmission opportunity i of carrier f in serving cell c; P PRACH,target,f,c represents the expected received power of the PRACH signal on carrier f in serving cell c; PL b,f,c It represents the path loss of the uplink activation bandwidth part b on the carrier f obtained based on the downlink reference channel on the downlink activation bandwidth of the service cell c associated with the PRACH transmission; min{A,B} represents the minimum value between A and B; δ1 represents the first offset value.

[0111] It can be seen from the above formula that the first offset value can also be used to calculate the increase in the random access sequence transmission power value.

[0112] In one embodiment, when the second information is received, the second information indicates a second offset value; the second offset value is different from the first offset value; the second offset value is used to determine the amount to increase when calculating the random access sequence transmission power; accordingly, the terminal uses the second offset value to determine the amount to increase when calculating the random access sequence transmission power.

[0113] Specifically, the terminal calculates the random access sequence transmit power using the following formula:

[0114] P PRACHb,f,c (i) = min{P cmax,f,c (i),P PRACH,target,f,c +PL b,f,c +δ2} (4)

[0115] Wherein, δ2 represents the second offset value.

[0116] In one embodiment, when the terminal receives the second information, the second information indicates that the random access sequence transmission power is determined based on the resources of the second synchronization signal; the identifiers of the first synchronization signal and the second synchronization signal are the same or different; and the terminal determines the random access sequence transmission power using the resources of the second synchronization signal. That is, the terminal performs path calculation based on the resources of the newly allocated synchronization signal to determine the random access sequence transmission power.

[0117] Here, the terminal can determine the corresponding PL according to the second synchronization signal (downlink reference signal). b,f,c , and determine the corresponding offset value (such as the one configured on the network side), and then use the following formula to calculate the random access sequence transmit power:

[0118] P PRACHb,f,c (i) = min{P cmax,f,c (i),P PRACH,target,f,c +PL b,f,c +δ3} (5)

[0119] In one embodiment, the terminal may receive the second information through SIB.

[0120] The present application also provides an information configuration method, such as Figure 4 As shown, the method includes:

[0121] Step 401: The network device configures first information through the MIB or SIB corresponding to the first synchronization signal, and configures or does not configure second information to indicate whether the first offset value is used to calculate the random access sequence transmit power; the first information indicates the first offset value;

[0122] Step 402: After receiving the first information, the terminal determines whether the first offset value is used to calculate the random access sequence transmission power according to the situation of receiving the second information.

[0123] Here, it should be noted that the specific processing process of the network device and the terminal has been described in detail above and will not be repeated here.

[0124] In the information configuration method provided in the embodiment of the present application, the network device configures the first information through the MIB or SIB corresponding to the first synchronization signal, and configures or does not configure the second information to indicate whether the first offset value is used to calculate the random access sequence transmit power; the first information indicates the first offset value; and after the terminal receives the first information, it determines whether the first offset value is used to calculate the random access sequence transmit power according to the situation of receiving the second information. The solution provided in the embodiment of the present application can realize that the network side instructs the terminal to determine the random access sequence transmit power in a collaborative manner or a non-collaborative manner through different offset values, thereby ensuring the performance of uplink access and reducing the access delay.

[0125] The embodiment of the present application also provides a data transmission device, which is arranged on a network device, such as Figure 5 As shown, the device comprises:

[0126] A first configuration unit 501 is configured to configure first information through a MIB or SIB corresponding to a first synchronization signal; the first information indicates a first offset value;

[0127] The second configuration unit 502 is used to configure or not configure second information to indicate whether the first offset value is used to calculate the random access sequence transmission power.

[0128] In one embodiment, the second configuration unit 502 is used to configure second information; the second information indicates a second offset value; the second offset value is different from the first offset value; the second offset value is used to determine the amount of increase when calculating the random access sequence transmission power.

[0129] In one embodiment, the second configuration unit 502 configures second information; the second information indicates a resource used to indicate determining a random access sequence transmission power based on a second synchronization signal; and the identifiers of the first synchronization signal and the second synchronization signal are the same or different.

[0130] In one embodiment, the second configuration unit 502 configures second information; the first information indicates an offset when calculating the random access sequence transmission power.

[0131] In one embodiment, the second configuration unit 502 configures the second information through SIB.

[0132] In actual application, the first configuration unit 501 and the second configuration unit 502 can be implemented by a processor in the information configuration device in combination with a communication interface.

[0133] In order to implement the method on the terminal side of the embodiment of the present application, the embodiment of the present application also provides an information configuration device, which is set on the terminal, such as Figure 6 As shown, the device comprises:

[0134] The receiving unit 601 is configured to receive first information through the MIB or SIB corresponding to the first synchronization signal; the first information indicates a first offset value;
