Description

Information determination method, device, equipment and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information determining method, an apparatus, a device, and a computer readable storage medium.

Background

In the prior art, after PDCP (Packet Data Convergence Protocol ) duplication is activated, the terminal has at most two legs, and the serving cells allowed to be used by the logical channels corresponding to the two legs are configured by the network through LCP (Logical Channel Prioritization, logical channel priority) restriction (restriction) corresponding to the logical channels. The terminal directly determines the LCP distribution of the logic channel corresponding to each of the multiple legs according to the network configuration, so as to determine the service cell allowed to be used by each leg.

But for subsequent versions the number of terminal activated duplicate legs may change. There is no scheme for how to determine the serving cell that each of the duplicate leg's corresponding logical channels is allowed to use in this case. Therefore, the PDCP multiplexing may not work properly in this case.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, fig. 1 is a flowchart of an information determining method provided in an embodiment of the present invention, which is applied to a terminal. As shown in fig. 1, the method comprises the following steps:

step 101, for a target bearer activated with PDCP multiplexing transmission, acquiring the number of multiplexing legs activated by the target bearer.

Step 102, determining a target service cell set which can be used by a logic channel corresponding to the target bearer according to the number of the activated multiplexing legs of the target bearer.

In this step, one implementation manner is that the terminal determines a target serving cell set that can be used by a logical channel corresponding to the target indication leg according to the configuration of the network device. For example, the terminal receives the number of different provisioning leg configured by the network device and the corresponding relation between the service cell sets corresponding to each provisioning leg under the circumstance of the number of the provisioning leg. After the PDCP multiplexing is activated by the bearer, the terminal determines a service cell set which can be used by a logic channel corresponding to each activated multiplexing leg currently according to the number of activated multiplexing legs and the corresponding relation configured by the network equipment.

In this implementation manner, the terminal may also send the number of the PDCP-duration activated duration leg to the network device under the condition that the PDCP-duration is activated by the terminal, so that the network device knows the number of leg of the terminal activated PDCP-duration and the allowed serving cell of the logical channel corresponding to each leg, so as to perform more accurate scheduling.

Specifically, the terminal receives the number of different provisioning leg configured by the network device and the corresponding relation between the service cell sets corresponding to each provisioning leg under the circumstance of the number of the provisioning leg. And then, according to the number of the target bearer activated multiplexing leg and the corresponding relation, determining a target service cell set which can be used by a logic channel corresponding to the target multiplexing leg.

In this step, specifically, when the network device configures the correspondence, RRC signaling configuration may be used, or MAC (Media Access Control, media access) CE (Control Element) configuration may be used. Then, correspondingly, the terminal may receive the correspondence configured by the network device through RRC signaling. Or, the terminal may receive the number of different multiplexing leg configured by the network device through the MAC CE and the corresponding relationship between the service cell set corresponding to each multiplexing leg under the circumstance of the number of the multiplexing leg; the MAC CE includes indication information, where the indication information is used to indicate that the MAC CE carries the correspondence.

If the network device configures the correspondence by using RRC signaling, the RRC signaling is further used to configure PDCP multiplexing for the target bearer. That is, the network device may configure the corresponding relationship at the same time when configuring PDCP multiplexing for the bearer. After that, the network device may also adjust the correspondence through an RRC reconfiguration procedure. Correspondingly, the terminal receives the corresponding relation between each of the multiple leg and the corresponding service cell set under the condition that the network equipment reconfigures the number of the multiple leg through the RRC signaling.

If the network equipment configures the corresponding relation through the MAC CE, the MAC CE signaling can be activated/deactivated to multiplex one MAC CE with the prior PDCP multiplexing; alternatively, a new MAC CE may be introduced. In either way, the network device needs to indicate that the corresponding relationship is carried in the MAC CE with a new LCID (logical channel identify, logical channel identification).

When determining the target service cell set which can be used by the logic channel corresponding to the target repetition leg, the terminal can determine the service cell set corresponding to each repetition leg according to the number of the repetition legs activated by the target bearer and the corresponding relation. And for the target effect of the target bearer, randomly selecting one service cell set which is not selected by other effect of the target bearer from the service cell sets, and taking the service cell set as a target service cell set which can be used by a logic channel corresponding to the target effect.

For example, assume that the network device configures two corresponding service cell sets to be { cell 1, cell 3}, { cell 2, cell 4}, respectively. After receiving the correspondence, the terminal may randomly select { cell 1, cell 3} or { cell 2, cell 4} for the first repetition leg, as long as the set of serving cells selected by the first repetition leg is not occupied by other repetition legs.

In this step, another implementation manner is that the terminal determines a target service cell set which can be used by a logic channel corresponding to the target implementation leg. For example, the terminal determines the set of service cells that can be used by the logic channel corresponding to each activated repetition leg according to a specific rule according to the number of activated cells and the number of activated repetition legs sent by the network device to the terminal.

Specifically, in this step, the terminal determines the number M of service cells currently activated or configured, and determines the number N of the duplicate legs of the target bearer activation. And then, the terminal determines a target service cell set which can be used by a logic channel corresponding to the target effect according to the activated or configured service cell number M and the effect log number N of the target bearing activation.

Specifically, in this implementation manner, the manner in which the terminal determines the target serving cell set that can be used by the logical channel corresponding to the target repetition leg includes:

in the first mode, the terminal sorts the M activated or configured serving cells according to a first order. Wherein the first order includes an order of the numbers of the serving cells from small to large or an order of the numbers of the serving cells from large to small. And then grouping the M activated or configured service cells after sequencing to obtain N service cell sets. And finally, respectively taking the N service cell sets as target service cell sets which can be used by N multiplexing legs activated by the target bearer.

The 1 st service cell set is to the N-1 st service cell set, and the number of cells in each service cell set is as follows:the number of cells in the nth serving cell set is: />Wherein M and N are positive integers, M represents the number of activated or configured service cells, N representsThe number of the duplicate legs of the target bearer activation is shown; />Representation pair->The result of (2) is rounded up.

Wherein each active repetition leg corresponds to a set of serving cells. The correspondence between the activated repetition leg and the set of serving cells may depend on the implementation of the terminal, among other things.

And secondly, the terminal orders the M activated or configured service cells according to a second sequence of channel quality measurement results. Wherein the second order includes an order of good to bad channel quality measurements or an order of bad to good channel quality measurements. And then, sequentially distributing the sequenced M activated or configured service cells to N multiplexing leg by adopting a round distribution mode, so as to obtain a target service cell set which can be used by the N multiplexing legs activated by the target bearing. M and N are positive integers, M represents the number of activated or configured service cells, and N represents the number of the target bearer activated duration leg.

The round allocation mode refers to that the M service cells which are ordered are sequentially and alternately allocated to the N multiple legs, and the round allocation can be repeated. In this way, the signal level between the serving cells of the respective multiplexing leg can be ensured to be comparable.

For example, the M activated or configured serving cells may be ranked in order of good to bad channel quality measurement (e.g., RSRP (Reference Signal Receiving Power, reference signal received power) or RSRQ (Reference Signal Receiving Quality, reference signal received quality)) results for the cells to obtain a channel quality ranking queue. And then sequentially distributing the first and second multiplexing regs and … … Nth multiplexing regs to each service cell in the channel quality sequencing queue according to the sequence. If the channel quality queue has allocatable service cells, performing a second round of allocation in the same manner, and finally obtaining a service cell set corresponding to each repetition leg.

In this implementation, the network device may determine, in the same manner as the terminal, a set of serving cells corresponding to each active repetition leg of the terminal. The terminal does not need to display the service cell set corresponding to each activated duplicate leg of the notification network device.

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

step 201, sending the number of different copies and the corresponding service cell set of each copy under the condition of the number of copies to a terminal, or sending the number of copies activated by a target bearer to the terminal, so that the terminal determines a target service cell set usable by a logic channel corresponding to the target copy according to the number of copies activated by the target bearer;

Specifically, the network device may send the correspondence through RRC signaling; or sending the corresponding relation through an MAC CE, wherein the MAC CE comprises indication information, and the indication information is used for indicating that the corresponding relation is carried in the MAC CE.

If the network device configures the correspondence by using RRC signaling, the RRC signaling is further used to configure PDCP multiplexing for the target bearer. That is, the network device may configure the corresponding relationship at the same time when configuring PDCP multiplexing for the bearer. After that, the network device may also adjust the correspondence through an RRC reconfiguration procedure. And then, the network equipment sends the number of the different reconfigured effects and the corresponding relation between the service cell sets corresponding to each effect under the condition of the number of the effects to the terminal through the RRC signaling.

In addition, the network device can also receive the number of the PDCP-multiplexing-activated multiplexing-cells sent by the terminal under the condition that the PDCP multiplexing is activated by the terminal, so that the network device knows the number of the PDCP-multiplexing-activated-cells of the terminal and the service cells allowed to be used by the logical channel corresponding to each of the multiplexing-cells, so as to perform more accurate scheduling.

Aiming at the problems in the prior art, in the embodiment of the invention, after a terminal determines that a certain bearer activates PDCP (packet data protocol) multiplexing, the terminal determines a service cell set which can be used by a logical channel corresponding to each activated multiplexing according to the number of the multiplexing leg activated by the bearer.

Hereinafter, the implementation procedure of the data repetition transmission method according to the embodiment of the present invention will be described in detail with reference to specific embodiments.

In the embodiment shown in fig. 3, the network device configures, through RRC signaling, a set of serving cells corresponding to each of the multiple copies in the case of different numbers of the multiple copies. As shown in fig. 3, the data retransmission method according to the embodiment of the present invention includes:

step 301, the network device configures a service cell set corresponding to each of the multiple copies under the condition of different numbers of the multiple copies through RRC signaling.

If RRC signaling is used, when PDCP multiplexing is configured for the bearer, the serving cell set corresponding to each multiplexing leg can be configured simultaneously with different numbers of multiplexing legs. Subsequently, if the service cell set corresponding to each of the multiple copies under the condition of the number of the multiple copies needs to be adjusted, the service cell set corresponding to each of the multiple copies under the condition of the number of the multiple copies can be adjusted through an RRC reconfiguration process.

Step 302, the terminal determines that a certain bearer activates PDCP multiplexing.

Step 302 may be implemented by either step 302a or step 302 b. Step 302a is PDCP multiplexing activation controlled by the network device; step 302b is the PDCP multiplexing activation controlled by the terminal itself. The terminal can also send the number of the PDCP-duration activating copies to the network device under the condition that the PDCP-duration is activated by the terminal, so that the network device knows the number of the copies of the PDCP-duration activating copies of the terminal and the service cells allowed to be used by the logical channels corresponding to each of the copies, so as to perform more accurate scheduling.

Step 303, the terminal determines a service cell set corresponding to each activation repetition leg for the bearer activated with PDCP repetition.

After the PDCP multiplexing is activated by the bearer, the terminal may determine a set of serving cells that may be used by a logical channel corresponding to each active leg currently according to the number of activated multiplexing legs and the set of serving cells corresponding to each multiplexing leg under the condition of the number of multiplexing legs configured by the network device in step 301.

For example, the network device may configure the contents of table 1 below in step 301:

TABLE 1

The specific which usage of which group of serving cells by the duplication leg may depend on the terminal implementation. For example, when the number of active effect legs is 3, the set of service cells that can be used by the logic channel corresponding to effect leg1 is { Cell2, cell4, cell6}; the set of service cells that can be used by the logical channel corresponding to the duplicate leg2 is { Cell 3, cell 7}; the set of serving cells that can be used for the logical channel corresponding to the repetition leg3 is { Cell 1, cell 5}.

Step 304, the terminal organizes the MAC PDU (Protocol Data Unit ) according to the set of service cells that can be used by the logical channel corresponding to each multiplexing leg.

That is, when the terminal organizes the MAC PDU, the data on the logical channel corresponding to each repetition leg only allows transmission by using the resources on the serving cell that the logical channel allows to use.

In the embodiment shown in fig. 4, the network device configures, through MAC signaling, a set of serving cells corresponding to each of the multiple copies in the case of different numbers of the multiple copies. As shown in fig. 4, the data retransmission method according to the embodiment of the present invention includes:

step 401, the network device configures a service cell set corresponding to each of the multiple registration leg under the condition of different numbers of the multiple leg through the MAC signaling.

If a MAC CE is employed and PDCP multiplexing is activated by the network device, steps 401 and 402a may be combined. The MAC CE can multiplex the existing PDCP multiplexing to activate the MAC CE, or can introduce a new independent MAC CE. Either way, the new LCID needs to be used to indicate the MAC CE.

Content contained in MAC CE: each active leg corresponds to a usable serving cell number or a bitmap indication of a usable serving cell. Taking activation of 3 multiplexing legs, the number of cells activated by the terminal is 8 as an example, and the MAC CE format is shown in the following table 2:

Wherein Cxy represents a bitmap indication of the logical channel corresponding to the x+1st repetition leg using the y-th active serving cell. If the value is 1, the use can be indicated; conversely, if the value is 0, the use is not possible.

Step 402, the terminal determines that a certain bearer activates PDCP multiplexing.

Step 402 may be implemented by step 402a or step 402 b. Step 402a is PDCP multiplexing activation controlled by the network device; step 402b is PDCP multiplexing activation controlled by the terminal itself. The terminal can also send the number of the PDCP-duration activating copies to the network device under the condition that the PDCP-duration is activated by the terminal, so that the network device knows the number of the copies of the PDCP-duration activating copies of the terminal and the service cells allowed to be used by the logical channels corresponding to each of the copies, so as to perform more accurate scheduling.

Step 403. The terminal determines a service cell set corresponding to each activation duration of the PDCP duration activated bearer. Carrying out

After the PDCP multiplexing is activated by the bearer, the terminal may determine, according to the number of activated multiplexing leg and the number of service cell sets corresponding to each multiplexing leg configured by the network device in step 401, a service cell set that may be used by a logical channel corresponding to each activating multiplexing leg currently.

For example, the network device may configure the contents of table 3 below in step 401:

TABLE 3 Table 3

Step 404, the terminal organizes the MAC PDU according to the set of service cells that can be used by the logical channel corresponding to each repetition leg.

In the embodiment shown in fig. 5, the terminal determines, according to a specific rule, a set of service cells that can be used by a logical channel corresponding to each activation repetition leg according to the number of activation service cells configured by the network device for the terminal and the number of activation repetition legs. As shown in fig. 5, the data retransmission method according to the embodiment of the present invention includes:

step 501, the terminal determines that a certain bearer activates PDCP multiplexing.

Step 501 may be implemented by step 501a or step 501 b. Step 501a is PDCP multiplexing activation controlled by the network device; step 501b is PDCP multiplexing activation controlled by the terminal itself. The terminal can also send the number of the PDCP-duration activating copies to the network device under the condition that the PDCP-duration is activated by the terminal, so that the network device knows the number of the copies of the PDCP-duration activating copies of the terminal and the service cells allowed to be used by the logical channels corresponding to each of the copies, so as to perform more accurate scheduling.

Step 502, the terminal determines a set of serving cells corresponding to each active leg for the bearer activated with PDCP multiplexing.

And the terminal automatically determines a service cell set which can be used by a logic channel corresponding to each activation repetition leg according to a specific rule according to the number of the activation service cells and the number of the activation repetition legs configured by the network equipment for the terminal. In this embodiment, the network device may determine, according to the same manner as the terminal, a set of serving cells corresponding to each activation duration of the terminal, and the terminal does not need to display a set of serving cells corresponding to each activation duration of the notification network device.

The specific determining mode of the specific terminal can be as follows:

and if the number of the activated service cells is M and the number of the activated repetition legs is N, grouping the activated service cells according to the sequence from small cell numbers to large cell numbers. The number of cells in each group except the last group isThe last group of cells has a number of +.>Each activation duration leg corresponds to a group of cells. The correspondence between a particular leg and active cell group may depend on the terminal implementation.

For example, the number of activated cells in a cell is 8, and the numbers are respectively: cell1,Cell3,Cell 5,Cell 6,Cell 7,Cell8,Cell 9,Cell11. The number of the Duplication legs is 3, and the number can be obtained according to the formula: the set of service cells that can be used by the logical channel corresponding to the duplicate leg1 is { Cell1, cell3, cell 5}; the set of service cells that can be used by the logical channels corresponding to the duplicate leg2 is { Cell 6, cell 7, cell8}; the set of serving cells that can be used for the logical channel corresponding to the repetition leg3 is { Cell 9, cell11}.

In step 503, the terminal organizes the MAC PDU according to the set of service cells that can be used by the logical channel corresponding to each repetition leg.

In the embodiment shown in fig. 6, the terminal determines, according to a specific rule, a set of service cells that can be used by a logical channel corresponding to each active leg according to the number of active service cells configured by the network device for the terminal and the number of active duration legs. As shown in fig. 6, the data retransmission method according to the embodiment of the present invention includes:

in step 601, the terminal determines that a certain bearer activates PDCP multiplexing.

Step 601 may be implemented by step 601a or step 601 b. Step 601a is PDCP multiplexing activation controlled by the network device; step 601b is PDCP multiplexing activation controlled by the terminal itself. The terminal can also send the number of the PDCP-duration activating copies to the network device under the condition that the PDCP-duration is activated by the terminal, so that the network device knows the number of the copies of the PDCP-duration activating copies of the terminal and the service cells allowed to be used by the logical channels corresponding to each of the copies, so as to perform more accurate scheduling.

Step 602, the terminal determines a set of serving cells corresponding to each activation repetition leg for the bearer activated with PDCP repetition.

And the terminal automatically determines a service cell set which can be used by a logic channel corresponding to each activation repetition leg according to a specific rule according to the number of the activation service cells and the number of the activation repetition legs configured by the network equipment for the terminal. In this embodiment, the network device may determine, according to the same manner as the terminal, a set of serving cells corresponding to each active leg of the terminal, and the terminal does not need to display any more a set of serving cells corresponding to each active leg of the notification network device.

The specific determining mode of the specific terminal can be as follows:

the method comprises the steps that assuming that the number of activated service cells is M and the number of activated repetition legs is N, the activated service cells are sequenced according to the sequence from good to bad of channel quality measurement results of the cells to obtain a channel quality sequencing queue, and then each cell in the channel quality sequencing queue is sequentially distributed to a first leg, a second leg and an Nth leg of … … according to the sequence; if no cell exists in the channel quality queue, a second round of allocation is performed in the same manner, and finally a service cell set corresponding to each repetition leg is obtained.

For example, assuming that the number of active cells in a cell is 8, the ranking from good to bad according to the channel quality measurement result is: cell1,Cell 3,Cell 5,Cell 6,Cell 7,Cell8,Cell 9,Cell11. The number of the Duplication legs is 3, and the following can be obtained according to the above mode: the set of service cells that can be used by the logical channel corresponding to the duplicate leg1 is { Cell1, cell 6, cell 9}; the set of service cells that can be used by the logical channel corresponding to the duplicate leg2 is { Cell 3, cell 7, cell11}; the set of serving cells that can be used for the logical channel corresponding to the repetition leg3 is { Cell 5, cell 9}.

Step 603, the terminal organizes the MAC PDU according to the set of service cells that can be used by the logical channel corresponding to each repetition leg.

In the embodiment of the invention, the terminal can be supported to determine the service cell which each of the multiple legs is allowed to use according to the number of the leg activated by the PDCP multiple, so that the PDCP multiple can work normally.
