Description

Multi-carrier detection method and device and processor readable storage medium

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a method and an apparatus for detecting multiple carriers, and a storage medium readable by a processor.

Background

In the prior art, when a network node configures a PDCCH (Physical Downlink Control Channel) for a UE (User Equipment), the network node calculates the total number of BDs (Blind Detection) and non-overlapped CCEs (non-overlapped Control Channel elements) on a scheduling Carrier, and when a PCell (Primary Cell )/PSCell (Primary Secondary Cell, primary Secondary Cell) has different SCS (Sub-Carrier Spacing ), the current mechanism may have a problem of Carrier repetition calculation. Since there are two scheduling carriers, e.g., cell #1 and cell #2, cell #1 of the scheduled carrier is computed once according to SCS #1, and cell #2 of the scheduled carrier is computed once according to SCS # 2; the scheduled carriers are calculated twice, resulting in the total number of BD/CCEs that the UE actually needs to detect to listen to exceeding the capability limit of the UE itself.

For better understanding and description of aspects of the embodiments of the present disclosure, some technical terms used in the embodiments of the present disclosure will be briefly described below.

In a current NR (New Radio ) system, if a network side (network node) configures multiple carriers for a terminal (UE), the network side needs to calculate the total number of BD/CCEs according to a terminal capability, the number of configured carriers, the number of carriers under each SCS, and a BD/CCE capability limit in each slot or span of a time slot of the terminal. Since there is only one scheduling carrier for one scheduled carrier in Rel-15/16 release, the total number of BD/CCEs on the corresponding scheduling carrier can be calculated directly according to the aforementioned parameters for a specific scheduled carrier. Specifically, take the calculation formulas (1) and (2) in Rel-15 as an example (note that the ideas and principles of Rel-16 are completely the same, but M-TRP (Multiple-Transmission Reception Point) and Rel-16 PDCCH monitoring capability are considered).

Wherein, M is the total number of BD on all scheduling carriers with the same SCS in one slot; c is the total number of non-overlapped CCEs on all scheduling carriers with the same SCS within one slot.

The total number of BD/CCEs that the terminal can detect does not exceed the total number of BD/CCEs per scheduled carrier

And

in Rel-16 release, different SCS is allowed for scheduled and scheduled carriers. At this time, the scheduled carrier is classified into the carrier group of the scheduling carrier for calculation, that is, the total number of BD/CCEs of the scheduled carrier is calculated according to the SCS of the scheduling carrier.

In the Rel-17 dynamic spectrum sharing project, research is carried out on SCell scheduling PCell. The method has the main idea that the PCell is scheduled through the SCell, the congestion probability of the PDCCH is reduced, and the overall performance of the system is improved. For the scheduled PCell, the scheduling may be performed through the PDCCH transmitted on the SCell and the PDCCH transmitted on the PCell. Unlike current mechanisms, an NR PCell/PSCell that shares a spectrum with an LTE (Long Term Evolution) cell may be scheduled by two cells. And the PCell/PSCell may have a different SCS than the SCell that schedules the cell. In this scenario, there is no clear solution at present how to calculate the total number of BD/CCEs on all carriers.

When configuring the PDCCH for the terminal, the network side firstly calculates the total number of BD and non-overlapped CCEs on a scheduling carrier. And then, determining the BD or non-overlapped CCE upper limit which can be configured for each scheduled carrier according to the capacity limit of the BD and the non-overlapped CCE of each time slot on the single carrier.

When the PCell/PSCell is scheduled by two cells simultaneously, the current mechanism can be fully multiplexed if the scheduled and scheduled carriers have the same SCS. The method comprises the steps of firstly calculating the total number of the maximum BD/non-overlapped CCEs allowed on a scheduling carrier in a scheduling carrier and a scheduled SCS carrier group, and then distributing the BD/CCEs on the scheduling carrier for the scheduled carrier according to the limitation of the total number.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The multi-carrier detection method according to the above embodiment of the present application is fully and thoroughly described by the following embodiments:

in a first embodiment of the present application:

a plurality of scheduling carriers are configured for the scheduled carrier, and a typical example is a spectrum sharing scenario. Assume that the PCell of NR UE and LTE base station are deployed on the same frequency band. In order to avoid CRS (Cell Reference Signal) interference from the LTE system, the gNB needs to avoid REs (Resource elements) occupied by the LTE CRS when transmitting the NR PDCCH. In order to guarantee flexibility of network deployment and scheduling and reduce PDCCH block on NR PCell/PSCell, SCell is allowed to schedule PCell. At this time, a CSS (Common search space) or USS (UE-specific search space) on the PCell is still allowed to schedule the own carrier, and the PCell may have two scheduling carriers (N = 2), that is, the PCell and the SCell that schedules the PCell.

In one embodiment, a DSS (Dynamic Spectrum Sharing) scenario will be taken as an example, i.e., the PCell/PSCell is scheduled by the PCell/PSCell itself as well as the SCell. Of course, this embodiment is only one specific application of the method described in the present application, and this application does not exclude other application scenarios.

In one embodiment, the subcarrier spacing for the SCell for which the PCell/PSCell is scheduled is assumed to be 15kHz and the subcarrier spacing for the SCell for which the PCell/PSCell is scheduled is 30kHz. Meanwhile, suppose that the network side configures 5 carriers for the terminal, and the subcarrier intervals SCS of the 5 carriers are { PCell-15kHz, SCell #1-15kHz, SCell #2-30kHz, SCell #3-30kHz, SCell #4-30kHz }, respectively. Assume that the number of supportable carriers reported by the terminal is 4. Meanwhile, it is assumed that the PCell may perform scheduling through a PDCCH transmitted on the current carrier (PCell), for example, scheduling a PDSCH (Physical Downlink shared Channel) of the current carrier; scheduling may also be performed via PDCCH transmitted on SCell #2. In other words, the PCell has two scheduling carriers, i.e., PCell with 15kHz SCS and SCell #2 with 30kHz SCS. As shown in fig. 4, SCell #2 is a scheduling carrier of PCell and SCell #3, and SCell #1 and SCell #4 are scheduled by the carrier.

In one embodiment, as shown in fig. 4, the two scheduled carriers of the PCell are scheduled with different SCS at this time, i.e. 15kHz and 30kHz. The total number of BD and non-overlapped CCEs on the scheduling carrier is calculated by the following method:

when the total number of BD and non-overlapped CCEs on the scheduling carrier wave is calculated, the calculation is carried out according to SCS of PCell (15 kHz) or SCell (30 kHz) of the scheduling PCell. Specifically, the total BD and the non-overlapped CCE numbers are calculated according to the SCS of which carrier, and the base station and the terminal are determined in a protocol predefined manner, or the base station is notified through an explicit RRC signaling, which is not limited in the present application.

In one embodiment, the total number of BD and non-overlapped CCEs on the scheduling carrier is determined to be calculated according to the sub-carrier interval of the SCell, namely the scheduled PCell is treated as a carrier of 30kHz. Further, at this time, the 15kHz subcarrier spacing carrier group includes { SCell #1} one carrier, and the 30kHz subcarrier spacing carrier group includes { PCell, SCell #2, SCell #3, SCell #4} four carriers. For each subcarrier group, the number of BD and non-overlapped CCEs on the scheduled carrier with the corresponding SCS is calculated as follows. In this embodiment, a Rel-15 capable terminal is taken as an example, and of course, the method can be directly applied to Rel-16 and the following versions of the multi-carrier scheduling scenarios.

In one embodiment, for 15kHz carriers, the total number of BD and non-overlapped CCEs is calculated as follows:

for each scheduled carrier, the terminal does not expect to blind more than

Is not expected to exceed

For the 30kHz carrier, the total number of BD and non-overlapped CCEs is calculated according to the following formula:

for each scheduled carrier, the terminal does not expect to blindly detect more on all scheduled carriers

Not expecting to detect more than all scheduled carriers

Wherein, the first and the second end of the pipe are connected with each other,

the blind test capability reported by the terminal is provided,

SCS is 15X 2 ^μ The number of carriers in kHz is such that,

for the maximum number of blind detections in each slot on each carrier,

the maximum number of non-overlapped CCEs in each slot on each carrier.

For the scheduled PCell, according to the calculation mode, the base station and the terminal determine in a protocol predefined mode, or the base station determines that the maximum BD times which can be monitored on the PCell and the SCell #2 of the scheduled PCell are not more than 36 and the maximum non-overlapped CCE number is not more than 56 on two carriers of the PCell and the SCell #2 according to the 30kHz carrier through explicit RRC signaling notification. When the base station configures a search space for the terminal or performs a dropping operation on the terminal side, the base station performs the operations according to the maximum of 36 BD times and the maximum of 56 CCEs.

In one embodiment, taking Rel-15 capability as an example, the method can also be applied to Rel-16 capability carriers or carrier aggregation scenarios of later evolution, that is, BD/CCE limits on each carrier are defined in units of span or MO.

In example two of the present application:

a plurality of scheduling carriers are configured for the scheduled carrier, and a typical example is a spectrum sharing scenario. Assume that the PCell of NR UE and LTE base station are deployed on the same frequency band. To avoid CRS interference from LTE systems, the gNB needs to avoid REs occupied by LTE CRS when transmitting NR PDCCH. In order to ensure the flexibility of network deployment and scheduling and reduce the PDCCH block on the NR PCell/PSCell, the SCell is allowed to schedule the PCell. At this time, the CSS or USS on the PCell is still allowed to schedule the present carrier, and the PCell has two scheduling carriers, that is, the PCell and the SCell that schedules the PCell.

In one embodiment, a dynamic spectrum sharing DSS scenario will be taken as an example, i.e., the PCell/PSCell is scheduled by the PCell/PSCell itself as well as the SCell. Of course, this embodiment is only one specific application of the method described in this patent, and this patent does not exclude other application scenarios.

In one embodiment, assuming a PCell/PSCell subcarrier spacing of 15kHz, the SCell subcarrier spacing for scheduling the PCell/PSCell is 60kHz. Meanwhile, suppose that the network side configures 5 carriers for the terminal, and SCS of the carriers is { PCell-15kHz, SCell #1-30kHz, SCell #2-60kHz, SCell #3-60kHz, SCell #4-60kHz }. It is assumed that the number of supportable carriers reported by the terminal is 4. Meanwhile, it is assumed that the PCell may perform scheduling through the PDCCH transmitted on the carrier, for example, scheduling the PDSCH of the carrier; scheduling may also be performed via PDCCH transmitted on SCell #2. In other words, the PCell has two scheduling carriers, namely PCell with 15kHz SCS and SCell #2 with 60kHz SCS. As shown in fig. 5, SCell #2 is the scheduling carrier of PCell and SCell #2, SCell #4 schedules SCell #3 and SCell #4, and SCell #1 schedules own carrier.

In one embodiment, as shown in fig. 5, the two scheduled carriers of the PCell are scheduled at this time with different SCS, i.e., 15kHz and 60kHz in the present embodiment, the total number of BD and non-overlapped CCEs on the scheduled carriers is calculated by:

and configuring the reference SCS of the N scheduling carriers for scheduling one carrier through RRC signaling.

In one embodiment, the total number of BD and non-overlaid CCEs on the scheduled carrier is calculated, and the scheduled PCell and the SCS of the SCell scheduling the PCell are considered as the reference SCS of the above configuration. In this embodiment, it is assumed that the reference SCS =30kHz for the RRC signaling configuration. At this time, the 30kHz alternate sub-carrier group includes three carriers { PCell, SCell #1, SCell #2}, and the 60kHz alternate sub-carrier group includes two carriers { SCell #3, SCell #4 }. For each subcarrier group, the number of BD and non-overlapped CCEs on the scheduled carrier with the corresponding SCS is calculated as follows. In this embodiment, a Rel-15 capable terminal is taken as an example, and of course, the method can be directly applied to Rel-16 and the following versions of the multi-carrier scheduling scenarios.

for each scheduled carrier, the terminal does not expect to blind more than

Is not expected to exceed

For the 60kHz carriers, respectively calculating the total number of BD and non-overlapped CCEs according to the following formulas:

Not expecting to detect more than all scheduled carriers

In example three of the present application:

this embodiment is described by taking the configuration described in the first embodiment as an example. Specific network side configuration and assumptions are described in the first embodiment, and details are not described in this embodiment.

In one embodiment, the total number of BD and non-overlapped CCEs on a scheduled carrier is calculated by:

and the network side respectively calculates the total number on the scheduling carrier waves with the same SCS according to the SCS of the N scheduling carrier waves, and subtracts a correction value from the total number of the BD/non-overlapped CCEs obtained by calculation.

In one embodiment, the total number of BD and non-overlapped CCEs on the scheduling carrier is calculated according to the sub-carrier interval of the SCell and the sub-carrier interval of the PCell respectively. Further, at this time, the 15kHz subcarrier spacing carrier group contains two carriers { PCell, SCell #1}, and the 30kHz subcarrier spacing carrier group contains four carriers { PCell, SCell #2, SCell #3, SCell #4} (note: according to the current method, when the scheduled carrier and the scheduling carrier have different SCSs, the total BD/CCE number of the scheduled carrier is calculated according to the SCS of the scheduling carrier). For each subcarrier group, the number of BD and non-overlapped CCEs on the scheduled carrier with the corresponding SCS is calculated as follows. In this embodiment, a Rel-15 capable terminal is taken as an example, and of course, the method can be directly applied to Rel-16 and subsequent versions of the multi-carrier scheduling scenarios.

For the 15kHz carrier, the total number of BD and non-overlapped CCEs is calculated according to the following formula:

as can be seen from the above calculation process, the scheduled PCell is actually calculated twice, that is, once according to the 15kHz subcarrier spacing and the 30kHz subcarrier spacing, respectively.

In one embodiment, a correction value Δ is subtracted from the total number of BD and non-overlapped CCEs calculated for 15kHz and/or 30kHz subcarrier spacing, respectively, and then compared to the terminal capability within each slot on each carrier. The correction value Δ may be determined according to the following method, which is not limited in this embodiment:

determining through RRC signaling sent by a base station;

or, determined by a protocol predefined manner;

or, the capability reported by the terminal is determined.

It should be noted that the correction value Δ may be applied to one or both of the two carrier groups, and when both of the two carrier groups need to be revised, the correction value Δ may be different, and the application is not limited in any way.

In one embodiment, assume that the correction value Δ BD =22 for BD and the correction value Δ CCE =28 for non-overlapped CCE, and are applied to two carrier groups simultaneously. The number of total BD and non-overlapped CCEs after correction is as follows:

for each scheduled carrier of 15kHz, the terminal does not expect to blind more than enough

Is not expected to exceed

For each scheduled carrier at 30kHz, the terminal does not expect to blindly detect more than on all scheduled carriers

Not expecting to detect more than all scheduled carriers

Wherein the content of the first and second substances,

the blind detection capability reported by the terminal is obtained,

SCS is 15X 2 ^μ The number of carriers in kHz is such that,

for the maximum number of blind detections in each slot on each carrier,

the maximum number of non-overlapped CCEs in each slot on each carrier.

In an embodiment, the present embodiment takes Rel-15 capability as an example, and may also be applied to a Rel-16 capability carrier or a carrier aggregation scenario of a subsequent evolution, that is, BD/CCE limits on each carrier are defined in units of span or MO (Monitoring location).

In example four of the present application:

In one embodiment, the total number of BDs and non-overlapped CCEs on a scheduled carrier is calculated by:

and respectively calculating the total number of BD/non-overlapped CCEs of total number #1, total number #2, \ 8230, total number N according to the SCS of the N scheduling carriers, and determining the final total number of the BD/non-overlapped CCEs in the following way:

min (total number #1, total number #2, \8230;, total number N), or

Max (total number #1, total number #2, \ 8230;, total number N), or

In one embodiment, the total number of BD and non-overlapped CCEs on the scheduling carrier is calculated according to the subcarrier spacing of the SCell and the subcarrier spacing of the PCell respectively. Further, at this time, the 15kHz subcarrier spacing carrier group includes two carriers { PCell, SCell #1}, and the 30kHz subcarrier spacing carrier group includes four carriers { PCell, SCell #2, SCell #3, SCell #4 }; it should be noted that, according to the current method, when the scheduled carrier and the scheduling carrier have different SCS, the total BD/CCE number of the scheduled carrier is calculated according to the SCS of the scheduling carrier. For each subcarrier group, the number of BD and non-overlapped CCEs on the scheduled carrier with the corresponding SCS is calculated as follows. In this embodiment, a Rel-15 capable terminal is taken as an example, and of course, the method can be directly applied to Rel-16 and subsequent versions of the multi-carrier scheduling scenarios.

then, according to the method, the calculated total BD and non-overlapped CCE numbers are respectively as follows:

method 1, taking the minimum value;

method 2, taking the maximum value;

method 3, average value

The subsequent steps are as described in embodiment one, embodiment two, and embodiment three, and this embodiment is not described again.

In an embodiment, the present embodiment takes Rel-15 capability as an example, and may also be applied to a Rel-16 capability carrier or a carrier aggregation scenario of a subsequent evolution, that is, BD/CCE limits on each carrier are defined in units of span or MO, and the like.

In example five of the present application:

the total number of BD/non-overlapped CCEs of #1, #2 and # 8230is obtained by calculation according to SCS of N scheduling carriers, and the maximum number of BD/non-overlapped CCEs on the scheduled carrier is determined according to the following method:

step1: for the carrier group with SCS # n, determining that the maximum BD/non-overlapped CCE number of the scheduled carrier on the scheduled carrier with SCS # n is not more than min (M) _{per-CC limit} ，M _total )，n＝1，2，…，N。

Step2: for the scheduled carrier, the sum of BD or non-overlapped CCEs on all the scheduled carriers does not exceed non-CA limit on the scheduled carrier.

In one embodiment, the total number of BD and non-overlapped CCEs on the scheduling carrier is calculated according to the subcarrier spacing of the SCell and the subcarrier spacing of the PCell respectively. Further, at this time, the 15kHz subcarrier spacing carrier group includes two carriers { PCell, SCell #1}, and the 30kHz subcarrier spacing carrier group includes four carriers { PCell, SCell #2, SCell #3, SCell #4 }; it should be noted that, according to the current method, when the scheduled carrier and the scheduling carrier have different SCS, the total BD/CCE number of the scheduled carrier is calculated according to the SCS of the scheduling carrier. For each subcarrier group, the number of BD and non-overlapped CCEs on the scheduled carrier with corresponding SCS is calculated as follows. In this embodiment, a Rel-15 capable terminal is taken as an example, and of course, the method can be directly applied to Rel-16 and subsequent versions of the multi-carrier scheduling scenarios.

for each SCS carrier group, the total number of maximum BD or non-overlapped CCEs per slot on each scheduling carrier of PCell is:

for a scheduled carrier of 15kHz

For a scheduled carrier of 30kHz

In one embodiment, for a scheduled PCell, the total number of BDs and non-overlapped CCEs on all scheduling cells is not greater than the per-slot capability of the PCell, i.e.:

the maximum number of BDs occupied by a terminal not expecting to detect PDCCH candidates receiving the scheduling PCell is larger than

The terminal does not expect to detect that the number of non-overlapped CCEs occupied by receiving PDCCH candidates of the scheduling PCell is more than:

in the embodiment of the application, when a plurality of scheduling carriers are configured for one scheduled carrier and a plurality of scheduling carriers SCS are different, the total number of BD and non-overlapped CCEs on the scheduling carriers is calculated, so that the problem of inconsistency of understanding of the configurable and detectable numbers of BD/CCEs on a network side and a terminal side can be solved.
