Detailed ways

The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

In the related art, if a terminal wants to obtain distributed cooperative distributed transmission, it needs to access the network first, and then can perform cooperative transmission on the service channel. If it is in a high-frequency and low-frequency cooperative network, this process is more lengthy, and the terminal needs to access the network once at the low frequency, and also needs to access the network once at the high frequency, and then can start cooperative transmission.

In view of the above problems, the synchronization signals (specifically, synchronization signal blocks (SSBs)) in the system can be divided into two categories: one is the ordinary synchronization signal (ie, the non-cooperative synchronization signal), and each TRP is in the synchronization signal of this type of synchronization signal. The synchronization signal is sent independently at the location; the other type is the cooperative synchronization signal. Different TRPs can cooperatively send the synchronization signal at the location of this type of synchronization signal. In this way, as shown in Figure 1, the terminal can measure the coordinated cell during the synchronization phase. Therefore, cooperative transmission is started in the access phase, as shown in Figure 1, so that there is no need to perform multiple measurements before accessing the network, reducing the delay and improving the rate or reliability of the access process.

In the above situation, the terminal will see two types of synchronization signals when performing cell search, one is the common synchronization signal, and the other is the coordinated synchronization signal. How to select the network and quickly access the network under the hybrid network) is an urgent problem to be solved.

In a distributed system, at the transmission position of the cooperative synchronization signal, multiple TRPs transmit the cooperative synchronization signal at the position in the form of a single frequency network (SFN, Single Frequency Network). When a terminal searches for a synchronization signal, it may search for multiple synchronization signals including cooperative and non-cooperative synchronization signals. Since the cooperative synchronization signal adopts SFN transmission, when the terminal receives this kind of synchronization signal, 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 cooperative cell, because the RSRP of the cooperative synchronization signal is relatively high, the terminal will use this higher RSRP to estimate the path loss when performing random access power control, which results in the transmission of physical random access. The power of an incoming channel (PRACH, Physical Random Access CHannel) (that is, sending a preamble sequence (preamble in English)) is low. Under normal circumstances, the purpose of performing uplink power control on uplink signals is to reduce the interference of uplink signals to adjacent cells. However, in a cooperative system, at least on this coordinated PRACH resource, multiple cells can perform joint reception. Therefore, The problem of inter-cell interference is not serious, and if the received power on this resource is too low, it may cause the terminal's signal to be submerged, increasing the complexity of joint reception. While affecting the uplink reception performance, the preamble sequence may be retransmitted, which also leads to an excessively long access delay.

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

An embodiment of the present application provides an information configuration method, which is applied to a network device (specifically, a base station). As shown in FIG. 2 , the method includes:

Step 201: configure first information by using the MIB or SIB corresponding to the first synchronization signal; the first information indicates a first offset value;

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.

Wherein, in step 202, the second information is configured or not configured, so that the terminal can judge whether the first offset value is used to calculate the transmission power of the random access sequence.

Wherein, in

steps

201 and 202, it can be understood that the terminal is configured with the first information, and the second information is configured or not configured.

In practical application, the terminal may be called a user equipment (UE), and may also be called a user.

The network device may configure the terminal to receive a first type of synchronization signal and/or a second type of synchronization signal; the first type of synchronization signal includes a cooperative synchronization signal; correspondingly, the second type of synchronization signal includes a non-cooperative synchronization signal. For cooperative synchronization signals, multiple TRPs cooperatively send synchronization signals at corresponding positions; correspondingly, for non-cooperative synchronization signals, each TRP independently sends synchronization signals at corresponding positions.

Here, in practical application, the synchronization signal may specifically be an SSB, and the offset value may also be called an offset, which is not limited in this embodiment of the present application.

The first synchronization signal includes a cooperative synchronization signal.

The size of the first offset value is related to the number of TRPs at the transmission position of the currently coordinated synchronization signal, and the more the number of coordinated TRPs is, the larger the first offset value is. For example, the size of the first offset value can be configured to be proportional to the number of TRPs; for example, there are two cooperative synchronization signals, the number of TRPs coordinated on the first cooperative synchronization signal is 2, and the number of TRPs coordinated on the second cooperative synchronization signal is 2. If the number of cooperative TRPs on the synchronization signal is 4, then the offset value corresponding to the first cooperative synchronization signal can be configured to be 3dB; the offset value corresponding to the second cooperative synchronization signal can be configured to be 6dB.

As mentioned above, when a terminal searches for a synchronization signal, it may search for multiple synchronization signals including cooperative and non-cooperative synchronization signals. Since the cooperative synchronization signal adopts SFN transmission, when the terminal receives this kind of synchronization signal, the corresponding RSRP is likely to be higher than that of the non-cooperative synchronization signal, which may cause a large number of terminals to wish to synchronize through cooperative synchronization. signal access to the network. 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 some cooperative nodes among the cooperative nodes, but is not far from the cooperative nodes Other nodes in the terminal are far away, and the actual cooperation effect cannot be guaranteed at this time, so it is not expected that such terminals can access the network in a cooperative manner.

Therefore, when a terminal selects a synchronization signal for access, it needs to distinguish between cell selection or cell reselection judgment criteria, that is, for a coordinated synchronization signal, the corresponding RSRP must be high enough to be selected for access. For example, if there are two TRPs in the current cooperative synchronization signal transmission position, the RSRP of the cooperative synchronization signal needs to be higher than the threshold of normal access to a non-cooperative cell by 3dB, so that the terminal can access the network on this cooperative synchronization signal. Therefore, according to the number of coordinated TRPs at the transmission position of the coordinated synchronization signal, the terminal can be notified of the corresponding threshold, and the terminal can select the cell, so as to realize the allocation of initial access resources between the coordinated and non-cooperative cells, and ensure the coordination User allocation ratio between cells and non-cooperating cells to avoid centralized access to cooperating cells due to excessive signal strength.

Based on this, in an 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 criterion, thus, After receiving the first information, the terminal may use the first information to determine the amount of decrease in the cell selection reception level value and/or the cell selection quality value corresponding to the first synchronization signal.

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

In practical application, the identifiers (eg IDs) corresponding to the cooperative synchronization signal and the non-cooperative synchronization signal are different.

In practical application, an offset value is introduced due to the consideration of cooperation among multiple TRPs, so the first offset value can be a relative value, which can be used to determine the transmission power of the random access sequence and also be used for The amount of decrease in the cell selection reception level value and/or the cell selection quality value corresponding to the first synchronization signal is determined.

In practical application, in step 202, configuring or not configuring the second information can play two different roles; specifically,

The first function is the function of direct confirmation (comform in English), that is, if the second information is configured, the first offset value can be directly determined and used to calculate the transmission power of the random access sequence. Correspondingly, the second information is not configured. Then, it can be directly determined that the first offset value is not used for calculating the transmission power of the random access sequence.

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

The second function is an indirect confirmation function, that is, if the second information is configured, the first offset value is indirectly determined not to be used to calculate the transmission power of the random access sequence; correspondingly, if the second information is not configured, the first offset value is indirectly determined. The shift value is used to calculate the transmit power of the random access sequence.

In this case, the network device may configure the second information for the terminal as required, or may not configure the second information for the terminal, for example, may be based on the number of TRPs that are coordinated when actually receiving PRACH to determine whether to configure the second information to the terminal. Exemplarily, if the number of TRPs coordinated at the transmission position of the first synchronization signal is the same as the number of TRPs coordinated when actually receiving PRACH, it is not necessary to send the second information to the terminal. The terminal configures the second information, so that the terminal uses the first offset value to calculate the random access sequence transmit power (that is, uses the first offset value to determine the random access sequence transmit power); if the first When the number of coordinated TRPs at the transmission position of the synchronization signal is less than the number of coordinated TRPs when actually receiving PRACH, the second information may be configured for the terminal.

Wherein, in an embodiment, when the second information indicates two offset values, the second offset value is different from the first offset value; the second offset value is used to determine the calculation of random access The amount by which the sequence transmit power is increased.

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

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

Based on this, in an embodiment, the second information indicates that the transmission power of the random access sequence 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.

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

The random access sequence transmit power may also be referred to as PRACH transmit power.

It can be seen from the above description that the solution provided by the embodiments of the present application ensures the power when PRACH is received for the network access mode in the cooperative mode. Since there is no inter-cell interference problem in this access mode, it can be improved through configuration. The transmission power of PRACH can speed up the access speed and reduce the access delay.

In an embodiment, the network device may configure the terminal with the second information through the SIB, so that the terminal can obtain the second information in time.

Correspondingly, an embodiment of the present application also provides an information configuration method, which is applied to a terminal. As shown in FIG. 3 , the method includes:

Step 301: Receive first information through the MIB or SIB corresponding to the first synchronization signal; the first information indicates a first offset value;

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

Wherein, the situation of receiving the second information includes receiving the second information or not receiving the second information.

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 transmission power of the random access sequence is different; specifically,

When the function of configuring or not configuring the second information is to directly confirm the function, and when the second information is not received, the terminal determines that the first offset value is not used to calculate the transmission power of the random access sequence; When the second information is used, the terminal determines that the first offset value is used to calculate the transmission power of the random access sequence, and at this time, the first information indicates the offset when calculating the transmission power of the random access sequence; The terminal uses the first information to determine the amount to increase when calculating the transmission power of the random access sequence.

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

In an embodiment, when the first at least instructs the terminal to calculate the cell selection criterion, the offset of the cell selection reception level value and/or the cell selection quality value corresponding to the first synchronization signal;

The terminal uses the first information to determine the amount of decrease in the cell selection reception level value and/or the cell selection quality value corresponding to the first synchronization signal.

Specifically, the terminal uses the following formula to calculate the cell selection criterion:

Srxlev=Q _rxlevmeas –(Q _rxlevmin +Q _{rxlevminoffset} )–P _compensation -Qoffset _temp -δ ₁ (1)

Squal=Q _qualmeas -(Q _qualmin +Q _{qualminoffset} )-Qoffset _temp -δ ₁ (2)

Among them, Srxlev represents the cell selection reception level value; Q _rxlevmeas represents the measured cell reception level value; Q _rxlevmin represents the minimum required cell reception level; Q _{rxlevminoffset} represents the Srxlev evaluation, when it resides in the access public land mobile network (VPLMN) normally, Offset value considered on Q _rxlevmin due to periodic search for higher priority public land mobile network (PLMN); P _compensation represents maximum power compensation value; Qoffset _temp represents currently configured cell offset value; Squal represents cell selection Quality value; Q _qualmeas indicates the quality value of the measured cell; Q _qualmin indicates the minimum required quality value of the cell; Q _{qualminoffset} indicates that during the Squal evaluation, when it normally resides in the VPLMN, it is on the Q _qualmin due to the periodic search for a higher priority PLMN Considered offset value; δ ₁ represents the first offset value.

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

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

Specifically, the terminal can use the following formula to calculate the transmission power of the random access sequence:

P _PRACHb,f,c (i)=min{P _cmax,f,c (i),P _{PRACH,target,f,c} +PL _b,f,c +δ ₁ }(3)

Among them, P _PRACHb,f ₍ _, ic ) represents the random access sequence transmit power on transmission opportunity i; P _cmax,fc, (i) represents the maximum output configured by the terminal on transmission opportunity i of carrier f in serving cell c power; P _{PRACH,target,f,c} represents the expected received power of the PRACH signal on carrier f of serving cell c; PL _b,f,c represents the downlink reference channel based on the downlink activation bandwidth of serving cell c associated with PRACH transmission The obtained path loss of the upstream active bandwidth part b on the carrier f; min{A, B} means taking the minimum value of A and B; δ ₁ means the first offset value.

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

Wherein, in an embodiment, when the terminal receives the second information, the second information indicates a second offset value; the second offset value is different from the first offset value; the first offset value The second offset value is used to determine the amount of increase when calculating the transmit power of the random access sequence; accordingly, the terminal uses the second offset value to determine the amount of increase when calculating the transmit power of the random access sequence.

Specifically, the terminal uses the following formula to calculate the transmission power of the random access sequence:

P _PRACHb,f,c (i)=min{P _cmax,f,c (i),P _{PRACH,target,f,c} +PL _b,f,c +δ ₂ }(4)

Wherein, δ ₂ represents the second offset value.

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

Here, the terminal can determine the corresponding PL _b,f,c according to the second synchronization signal (downlink reference signal), and determine the corresponding offset value (for example, configured by the network side), and then use the following formula to calculate the random access Sequence transmit power:

P _PRACHb,f,c (i)=min{P _cmax,f,c (i),P _{PRACH,target,f,c} +PL _b,f,c +δ ₃ }(5)

In an embodiment, the terminal may receive the second information through the SIB.

The embodiment of the present application also provides an information configuration method, as shown in FIG. 4 , the method includes:

Step 401: 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 transmission power of the random access sequence; the first information indicates a first offset value;

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

Here, it should be noted that the specific processing procedures of the network device and the terminal have been described in detail above, and will not be repeated here.

In the information configuration method provided by the embodiment of the present application, the network device configures the first information by using the MIB or SIB corresponding to the first synchronization signal, and configures or does not configure the second information, so as to indicate whether the first offset value is used to calculate the random The transmission power of the access sequence; 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 random access according to the situation of receiving the second information. incoming sequence transmit power. The solutions provided by the embodiments of the present application can realize that the network side instructs the terminal to determine the transmission power of the random access sequence in a cooperative manner or a non-cooperative manner through different offset values, thereby ensuring the performance of uplink access and reducing the access delay. .
