Detailed ways

The technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

Refer to FIG. 1, which is a flowchart of an information determination method provided by an embodiment of the present disclosure, which is applied to a terminal. As shown in Figure 1, it includes the following steps:

Step 101: For a target bearer that has activated PDCP duplication transmission, obtain the number of activated duplication legs of the target bearer.

Step 102: Determine the set of target serving cells that can be used by the logical channel corresponding to the target duplication leg according to the number of activated duplication legs of the target bearer.

In this step, one of the implementation methods is that the terminal determines the set of target serving cells that can be used by the logical channel corresponding to the target duplication leg according to the configuration of the network device. For example, the terminal receives the correspondence between the number of different duplication legs configured by the network device and the set of serving cells corresponding to each duplication leg in the case of the number of duplication legs. After the bearer activates PDCP duplication, the terminal determines the set of serving cells that can be used by the logical channel corresponding to each activated duplication leg according to the number of activated duplication legs and the corresponding relationship of the network device configuration.

In this implementation manner, the terminal can also send the number of duplication legs activated by the PDCP duplication to the network device when the PDCP duplication is activated by the terminal itself, so that the network device knows that the terminal has activated PDCP duplication. The number of legs and the service cell allowed to be used by the logical channel corresponding to each leg can be used for more precise scheduling.

Specifically, the terminal receives the correspondence between the number of different duplication legs configured by the network device and the set of serving cells corresponding to each duplication leg in the case of the number of duplication legs. Then, according to the number of activated duplication legs of the target bearer and the corresponding relationship, a set of target serving cells that can be used by the logical channel corresponding to the target duplication leg is determined.

In this step, specifically, when the network device configures the foregoing corresponding relationship, it can be configured using RRC signaling, or it can be configured using a Media Access Control (MAC) control element (CE). Then, correspondingly, the terminal may receive the corresponding relationship configured by the network device through RRC signaling. Alternatively, the terminal may receive the corresponding relationship between the number of different duplication legs configured by the network device through the MAC CE and the set of serving cells corresponding to each duplication leg in the case of the number of duplication legs; wherein, in the MAC CE Including indication information, where the indication information is used to indicate that the MAC CE carries the corresponding relationship.

Wherein, if the network equipment uses RRC signaling to configure the foregoing correspondence, the foregoing RRC signaling is also used to configure PDCP duplication for the target bearer. That is, the network device can configure the above-mentioned correspondence when configuring PDCP duplication for the bearer. After that, the network device may also adjust the foregoing correspondence relationship through the RRC reconfiguration process. Correspondingly, the terminal receives the correspondence between each duplication leg and its corresponding serving cell set in the case of different duplication legs reconfigured by the network device through RRC signaling.

If the network device configures the above-mentioned correspondence through the MAC CE, the MAC CE signaling can be multiplexed with the PDCP duplication activation/deactivation in the related technology to multiplex a MAC CE; or, a new MAC CE can be introduced. No matter which method is used, the network device needs to use a new logical channel identity (LCID) to indicate that the MAC CE carries the corresponding relationship.

When determining the set of target serving cells that can be used by the logical channel corresponding to the target duplication leg, the terminal may determine the set of serving cells corresponding to each duplication leg according to the number of activated duplication legs of the target bearer and the corresponding relationship. For the target duplication leg of the target bearer, a serving cell set that is not selected by other duplication legs is randomly selected from the serving cell set as the target serving cell set that can be used by the logical channel corresponding to the target duplication leg.

For example, suppose that the network equipment configures the serving cell sets corresponding to two duplication legs to be {cell 1, cell 3}, {cell 2, cell 4}. After receiving the corresponding relationship, the terminal can select {cell 1, cell 3} or {cell 2, cell 4} for the first duplication leg at random, as long as the set of serving cells selected by the first duplication leg is not Other duplication leg can be occupied.

In this step, another implementation manner is that the terminal itself determines the set of target serving cells that can be used by the logical channel corresponding to the target duplication leg. For example, according to the number of activated cells and the number of activated duplication legs sent by the network device to the terminal, the terminal determines the set of serving cells that can be used by the logical channel corresponding to each activated duplication leg according to specific rules.

Specifically, in this step, the terminal determines the number M of currently activated or configured serving cells, and determines the number N of activated duplication legs of the target bearer. Then, the terminal determines the target serving cell that can be used by the logical channel corresponding to the target duplication leg according to the first preset rule, the number M of activated or configured serving cells and the number N of activated duplication legs of the target bearer set.

Specifically, in this implementation manner, the method for the terminal to determine the set of target serving cells that can be used by the logical channel corresponding to the target duplication leg includes:

Manner 1: The terminal sorts the M activated or configured serving cells in the first order. Wherein, the first order includes the order of serving cell numbers from small to large, or the order of serving cell numbers from large to small. Then, the sorted M activated or configured serving cells are grouped to obtain a set of N serving cells. Finally, the N serving cell sets are respectively used as target serving cell sets that can be used by the N duplication legs activated by the target bearer.

The number of cells in the Nth serving cell set is:

Means right

The result of is rounded up.

Among them, each activated duplication leg corresponds to a serving cell set. Among them, the correspondence between the activated duplication leg and the serving cell set may depend on the implementation of the terminal.

Manner 2: The terminal sorts the M activated or configured serving cells according to the second order of the channel quality measurement results. Wherein, the second order includes the order of channel quality measurement results from good to poor, or the order of channel quality measurement results from poor to good. Then, in a round allocation manner, the sorted M activated or configured serving cells are sequentially allocated to N duplication legs, so as to obtain a set of target serving cells that can be used by the N duplication legs activated by the target bearer. Among them, M and N are positive integers, M represents the number of activated or configured serving cells, and N represents the number of activated duplication legs of the target bearer.

Among them, the round allocation method refers to assigning the ordered M serving cells to N duplication legs in turn, and multiple rounds of allocation can be repeated. In this way, it can be ensured that the signal levels between the serving cells of each duplication leg are equal.

For example, M activated or configured serving cells can be measured according to the channel quality of the cell (such as Reference Signal Receiving Power (RSRP) or Reference Signal Receiving Quality (Reference Signal Receiving Quality, RSRQ)). The poor order is sorted to obtain the channel quality sorting queue. Then, each serving cell in the queue is sorted by channel quality and assigned to the first duplication leg, the second duplication leg, and the Nth duplication leg in sequence. If there are still allocatable serving cells in the channel quality queue, the second round of allocation is performed in the same way, and finally a set of serving cells corresponding to each duplication leg is obtained.

In this implementation manner, the network device can determine the set of serving cells corresponding to each activated duplication leg of the terminal in the same manner as the terminal. The terminal does not need to display the set of serving cells corresponding to each activated duplication leg to notify the network equipment.

In this implementation manner, the terminal can also send the number of duplication legs activated by the PDCP duplication to the network device when the PDCP duplication is activated by the terminal itself, so that the network device knows that the terminal has activated PDCP The number of legs of duplication and the allowed serving cell of the logical channel corresponding to each leg can be used for more precise scheduling.

Fig. 2 is a flowchart of an information determination method provided by an embodiment of the present disclosure, which is applied to a network device, as shown in Fig. 2, includes the following steps:

Step 201: Send the corresponding relationship between the set of serving cells corresponding to each duplication leg in the case of different duplication legs and the number of duplication legs to the terminal, or send to the terminal the number of duplication legs activated by the target bearer , So that the terminal determines the set of target serving cells that can be used by the logical channel corresponding to the target duplication leg according to the number of duplication legs activated by the target bearer;

Specifically, the network device may send the corresponding relationship through RRC signaling; or send the corresponding relationship through MAC CE, where the MAC CE includes indication information, and the indication information is used to indicate that the MAC CE carries The corresponding relationship.

Wherein, if the network equipment uses RRC signaling to configure the foregoing correspondence, the foregoing RRC signaling is also used to configure PDCP duplication for the target bearer. That is, the network device can configure the above-mentioned correspondence when configuring PDCP duplication for the bearer. After that, the network device may also adjust the foregoing correspondence relationship through the RRC reconfiguration process. Then, the network device sends the number of reconfigured different duplication legs and the corresponding relationship between the serving cell set corresponding to each duplication leg to the terminal through RRC signaling.

In addition, the network device may also receive the number of PDCP duplication activated duplication legs sent by the terminal when the PDCP duplication is activated by the terminal itself, so that the network device knows the number of PDCP duplication activated legs of the terminal and The serving cell that the logical channel corresponding to each leg is allowed to use for more precise scheduling.

In response to related technical problems, in the embodiments of the present disclosure, after determining that a certain bearer activates PDCP duplication, the terminal determines the set of serving cells that can be used by the logical channel corresponding to each activated duplication leg according to the number of activated duplication legs of the bearer .

Hereinafter, the implementation process of the data repeated transmission method in the embodiment of the present disclosure will be described in detail with reference to specific embodiments.

In the embodiment shown in FIG. 3, the network device configures the set of serving cells corresponding to each duplication leg in the case of different duplication leg numbers through RRC signaling. As shown in FIG. 3, the data repeated transmission method of the embodiment of the present disclosure includes:

Step 301: The network device configures a set of serving cells corresponding to each duplication leg in the case of different duplication leg numbers through RRC signaling.

If RRC signaling is used, the set of serving cells corresponding to each duplication leg can be configured at the same time when the PDCP duplication is configured for the bearer. Later, if it is necessary to adjust the set of serving cells corresponding to each duplication leg under different number of duplication legs, the set of serving cells corresponding to each duplication leg can be adjusted through the RRC reconfiguration process.

Step 302: The terminal determines that a certain bearer has activated PDCP duplication.

Step 302 can be implemented by step 302a or step 302b. Step 302a is the activation of PDCP duplication controlled by the network device; step 302b is the activation of PDCP duplication controlled by the terminal itself. The terminal may also send the number of PDCP duplication activated duplication legs to the network device in the case that PDCP duplication is activated by the terminal itself, so that the network device knows the number of PDCP duplication activated legs and each leg The serving cell allowed to be used by the logical channel corresponding to the leg for more precise scheduling.

Step 303: The terminal determines a set of serving cells corresponding to each activated duplication leg for the bearer with activated PDCP duplication.

After PDCP duplication is activated by the bearer, the terminal can determine the set of serving cells corresponding to each duplication leg according to the number of activated duplication legs and the number of duplication legs configured by the network device in step 301. The set of serving cells that the logical channel corresponding to the leg can use.

For example, in step 301, the network device can be configured with the following table 1 content:

Table 1

Which duplication leg uses which group of serving cells can depend on the terminal implementation. For example, when the number of activated duplication leg is 3, the set of serving cells that can be used by the logical channel corresponding to duplication leg1 is {Cell2, Cell4, Cell6}; the set of serving cells that can be used by the logical channel corresponding to duplication leg2 is {Cell 3,Cell 7}; The set of serving cells that can be used by the logical channel corresponding to duplication leg3 is available {Cell 1, Cell 5}.

Step 304: The terminal organizes a MAC protocol data unit (Protocol Data Unit, PDU) according to the set of serving cells that can be used by the logical channel corresponding to each duplication leg.

That is to say, when the terminal organizes the MAC PDU, the data on the logical channel corresponding to each duplication leg is only allowed to use the resources on the serving cell allowed to be used by the logical channel for transmission.

In the embodiment shown in FIG. 4, the network device configures the set of serving cells corresponding to each duplication leg in the case of different duplication leg numbers through MAC signaling. As shown in FIG. 4, the data repeated transmission method of the embodiment of the present disclosure includes:

Step 401: The network device configures a set of serving cells corresponding to each duplication leg in the case of different duplication leg numbers through MAC signaling.

If MAC CE is adopted, and the activation of PDCP duplication is controlled by the network device, step 401 and step 402a can be combined. The MAC CE may reuse PDCP duplication in related technologies to activate the MAC CE, or introduce a new separate MAC CE. Either way, a new LCID needs to be used to indicate the MAC CE.

The content contained in the MAC CE: each active leg corresponds to the available serving cell number or the available serving cell bitmap indication. Taking 3 duplication legs activated, the number of cells activated by the terminal is 8 as an example, an example of the MAC CE format is shown in Table 2 below:

Table 2

C ₀₇ C ₀₇	C ₀₆ C ₀₆	C ₀₅ C ₀₅	C ₀₄ C ₀₄	C ₀₃ C ₀₃	C ₀₂ C ₀₂	C ₀₁ C ₀₁	C ₀₀ C ₀₀
C ₁₇ C ₁₇	C ₁₆ C ₁₆	C ₁₅ C ₁₅	C ₁₄ C ₁₄	C ₁₃ C ₁₃	C ₁₂ C ₁₂	C ₁₁ C ₁₁	C ₁₀ C ₁₀
C ₂₇ C ₂₇	C ₂₆ C ₂₆	C ₂₅ C ₂₅	C ₂₄ C ₂₄	C ₂₃ C ₂₃	C ₂₂ C ₂₂	C ₂₁ C ₂₁	C ₂₀ C ₂₀

Among them, Cxy represents that the logical channel corresponding to the x+1th duplication leg uses the bitmap (bitmap) indication of the yth activated serving cell. If the value is 1, it means it can be used; otherwise, if it is 0, it means it cannot be used.

Step 402: The terminal determines that a certain bearer has activated PDCP duplication.

Step 402 can be implemented by step 402a or step 402b. Step 402a is the activation of PDCP duplication controlled by the network device; step 402b is the activation of PDCP duplication controlled by the terminal itself. The terminal may also send the number of PDCP duplication activated duplication legs to the network device in the case that PDCP duplication is activated by the terminal itself, so that the network device knows the number of PDCP duplication activated legs and each leg The serving cell allowed to be used by the logical channel corresponding to the leg for more precise scheduling.

Step 403. The terminal determines the set of serving cells corresponding to each activated duplication leg for the bearer with activated PDCP duplication. ·

After the PDCP duplication is activated by the bearer, the terminal can determine the set of serving cells corresponding to each duplication leg according to the number of activated duplication legs and the number of duplication legs configured by the network device in step 401, to determine the current activation The set of serving cells that can be used by the logical channel corresponding to the duplication leg.

For example, in step 401, the network device can be configured with the following table 3 content:

table 3

Step 404: The terminal organizes MAC PDUs according to the set of serving cells that can be used by the logical channel corresponding to each duplication leg.

In the embodiment shown in FIG. 5, the terminal determines the logical channel corresponding to each activated duplication leg according to specific rules according to the number of activated serving cells and the number of activated duplication legs configured by the network device for the terminal. Serving cell collection. As shown in FIG. 5, the data repeated transmission method of the embodiment of the present disclosure includes:

Step 501: The terminal determines that a certain bearer has activated PDCP duplication.

Step 501 can be implemented by step 501a or step 501b. Step 501a is the activation of PDCP duplication controlled by the network device; step 501b is the activation of PDCP duplication controlled by the terminal itself. The terminal may also send the number of PDCP duplication activated duplication legs to the network device in the case that PDCP duplication is activated by the terminal itself, so that the network device knows the number of PDCP duplication activated legs and each leg The serving cell allowed to be used by the logical channel corresponding to the leg for more precise scheduling.

Step 502: The terminal determines the set of serving cells corresponding to each activated leg for the bearer with activated PDCP duplication.

According to the number of activated serving cells and the number of activated duplication legs configured by the network equipment for the terminal, the terminal determines the set of serving cells that can be used by the logical channel corresponding to each activated duplication leg according to specific rules. In this embodiment, the network device can determine the serving cell set corresponding to each activated duplication leg of the terminal in the same manner as the terminal, and the terminal does not need to display and inform the network device of the serving cell set corresponding to each activated duplication leg.

The specific method for determining the specific terminal may be:

Assuming that the number of activated serving cells is M and the number of activated duplication legs is N, then the activated serving cells are grouped in ascending order of cell numbers. Except for the last group, the number of cells in each group is

The number of cells in the last group is

Each active duplication leg corresponds to a group of cells. The correspondence between the specific leg and the activated cell group may depend on the terminal implementation.

As an example, it is assumed that the number of activated cells in the cell is 8, and the numbers are: Cell 1, Cell 3, Cell 5, Cell 6, Cell 7, Cell 8, Cell 9, Cell 11. If the number of duplication leg is 3, according to the above formula, we can get: The set of service cells that can be used by the logical channel corresponding to duplication leg1 is {Cell 1, Cell 3, Cell 5}; the service that can be used by the logical channel corresponding to duplication leg2 The cell set is {Cell 6, Cell 7, Cell8}; the serving cell set that can be used by the logical channel corresponding to duplication leg3 is {Cell 9, Cell11}.

The specific method for determining the specific terminal may be:

Assuming that the number of activated serving cells is M and the number of activated duplication leg is N, then the activated serving cells are sorted according to the channel quality measurement results of the cells from good to bad to obtain the channel quality ranking queue, and then the channel quality ranking queue Each cell in the system is allocated to the first leg, the second leg, ... the Nth leg in sequence; if there is no cell in the channel quality queue, the second round is allocated in the same way, and the final result is The set of serving cells corresponding to each duplication leg.

An example is as follows, assuming that the number of activated cells in a cell is 8, and the channel quality measurement results are sorted from good to bad: Cell 1, Cell 3, Cell 5, Cell 6, Cell 7, Cell 8, Cell 9, Cell 11.
