Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In order to facilitate a clearer understanding of the embodiments of the present application, some related technical knowledge will be described first.

(1) Cellular network communication

The traditional wireless communication adopts a cellular network communication mode, namely, uplink and downlink data/control information transmission is carried out between a terminal and network side equipment through a Uu interface.

Fig. 1 is a schematic diagram of a cellular network communication system provided in an embodiment of the present application, as shown in fig. 1, UE1 communicates with a network side device through a Uu interface, UE2 also communicates with a network side device through the Uu interface, and the network side device also communicates with a Core Network (CN).

(2) Direct communication (Sidelink communication)

Direct communication refers to the manner in which nearby terminals can communicate data over a direct communication link (also known as a sidlink or PC 5) within a close range. The wireless interface to which the sidlink link corresponds is referred to as a direct communication interface (also referred to as a sidlink interface or PC5 interface).

Fig. 2 is a schematic diagram of direct communication provided in the embodiment of the present application, as shown in fig. 2, UE1 communicates with a network side device through a Uu interface, UE2 also communicates with a network side device through a Uu interface, UE1 and UE2 communicate with each other through a direct communication link, and the network side device also communicates with a Core Network (CN).

(3) Long term evolution (Long Term Evolution, LTE) SL carrier selection and reselection

LTE SL also supports multiple carriers, the specific carrier selection and reselection mechanisms are as follows:

1. carrier selection

The UE takes the carrier with the channel busy rate (Channel Busy Ratio, CBR) measurement result lower than the preset threshold as the candidate carrier, and then performs carrier selection according to the CBR value of the candidate carrier and the UE capability. For example, if the terminal is to select N (N is an integer greater than or equal to 1) carriers, the N carriers are sequentially selected according to the CBR value ascending order corresponding to the candidate carriers.

The CBR value is the percentage of subchannels in the resource pool for which the direct link-received signal strength indication (S-RSSI) measured within a time window exceeds a threshold.

2. Carrier reselection

The trigger conditions for LTE SL carrier reselection are as follows:

the higher-level configured traffic channel (Sidelink Traffic Channel, STCH) allows no direct communication grant (configured sidelink grant) to be configured for the direct communication process (sidelink process) on any of the carriers used;

if the STCH of the higher layer configuration allows a configured direct communication grant on the carrier used, then a reselection is triggered as well if one of the following conditions is met:

based on SL resource reselection counter, every time 1 Transport Block (TB) is transmitted, the counter is decremented by one, when the counter returns to zero, UE generates a random number between [0,1], if the random number is greater than the threshold, reselection is triggered;

During the past one second, none of the medium access control (Media Access Control, MAC) entities have transmitted or retransmitted over the configured direct communication grant;

when the number of continuous configuration direct communication grants of the UE in skip (skip) reaches a threshold of reselection;

none of the configuration grants (RLC SDUs) on the carrier that STCH allows to be used can carry the traffic data units (Radio Link Control Service Data Unit, RLC SDUs) of the radio link control layer to be transmitted;

none of the configuration grants on the carriers that the STCH allows to use can meet the latency requirement of the data that the UE is to transmit, and the UE chooses not to transmit MAC protocol data units (Protocol Data Unit, PDUs);

the radio resource control (Radio Resource Control, RRC) reconfigures the resource pool (resource pool) where the current direct communication grant (sidelink grant) is located.

Fig. 3 is one of flow diagrams of a carrier determining method provided in the embodiment of the present application, as shown in fig. 3, where an execution body of the carrier determining method may be a terminal, for example, a mobile phone, and the method includes:

in step 301, one or more available carriers are determined based on the priorities of the carriers.

In particular, the carrier may comprise a carrier and/or a fractional Bandwidth (BWP) on a carrier.

The priority of the carrier may be configured by the network device or may be preconfigured by the terminal.

The terminal determines one or more available carriers from the carriers with high priority based on the priority configuration condition of the carriers, and determines one or more available carriers from the carriers with low priority when no available carrier exists in the carriers with high priority.

The available carriers are carriers that can be used for data transmission to enable direct communication.

Step 302, determining a carrier for data transmission based on the one or more available carriers.

Specifically, after determining one or more available carriers, the one or more available carriers are ordered, and one or more carriers for data transmission are sequentially selected from the one or more available carriers.

According to the carrier determining method provided by the embodiment of the application, the available carriers are selected according to the priority of the carriers, and then the carriers used for data transmission are selected from the available carriers, so that direct communication between terminals is realized.

In some embodiments, the carrier comprises a licensed carrier or an unlicensed carrier or a combination of a licensed carrier and an unlicensed carrier.

Specifically, the one or more available carriers may be licensed carriers, unlicensed carriers, licensed carriers and unlicensed carriers.

The licensed carrier may include a licensed carrier and/or BWP on the licensed carrier. The unlicensed carrier may include an unlicensed carrier and/or BWP on an unlicensed carrier.

The priority of the licensed carrier and the priority of the unlicensed carrier may be configured on a per carrier basis. I.e. also the licensed carriers, the priorities corresponding to the different licensed carriers may be different. The same is true for unlicensed carriers, and the priorities corresponding to different unlicensed carriers may be different.

The priority configuration case for the licensed and unlicensed carriers may be: the priority of the licensed carrier is higher than the priority of the unlicensed carrier, which is higher than the priority of the licensed carrier, which is the same as the priority of the unlicensed carrier.

According to the carrier determining method, the carrier used for data transmission is preferentially selected from the carriers with high priority through the priority of the authorized carrier and the unauthorized carrier, and direct communication between terminals is further facilitated.

Specifically, fig. 4 is a second flow chart of the carrier determining method provided in the embodiment of the present application, as shown in fig. 4, when the priority of the unlicensed carrier is higher than that of the licensed carrier, the terminal monitors and/or measures a plurality of unlicensed carriers, that is, monitors only a plurality of unlicensed carriers, measures only a plurality of unlicensed carriers, or monitors both a plurality of unlicensed carriers.

The monitoring of the plurality of unlicensed carriers may be monitoring whether the unlicensed carriers occupy resources, and the monitoring result may be that the unlicensed carriers occupy resources.

The measurement of the plurality of unlicensed carriers may be a strength indication (Received Signal Strength Indicator, RSSI) measurement and/or a channel occupancy (Channel Occupancy, CO) measurement of the received signal of the unlicensed carrier, and the acquisition measurement may be an RSSI measurement and/or a CO measurement.

The specific process of CO measurement is as follows: the terminal obtains RSSI measurements at each measurement instant or symbol based on all received power (including co-channel signals, adjacent channel interference, thermal noise, etc.) over the measurement band. And in a certain duration, the terminal calculates average RSSI measured values according to the acquired RSSI measured values, and calculates the percentage of a certain number of average RSSI measured values which are larger than a preset threshold to obtain the CO measured values.

The first preset condition may be a condition set based on the number of times the unlicensed carrier occurrence resource is occupied.

For example, the first preset condition may be that the unlicensed carrier does not occupy resources in 3 listening periods nearest to the current moment.

The second preset condition may be a condition set based on an RSSI measurement value and/or a CO measurement value corresponding to the unlicensed carrier.

For example, the second preset condition may be that the RSSI measurement corresponding to the unlicensed carrier is less than-100 dBm.

The monitoring results corresponding to the unauthorized carriers are compared with a first preset condition, and the measuring results corresponding to the unauthorized carriers are compared with a second preset condition. After comparison, it is found that unlicensed carriers with monitoring results meeting a first preset condition and/or measuring results meeting a second preset condition exist in the plurality of unlicensed carriers.

And then the unauthorized carrier wave with the monitoring result meeting the first preset condition and/or the measurement result meeting the second preset condition is screened out, and the unauthorized carrier wave is determined to be an available unauthorized carrier wave.

The available unlicensed carrier may be an unlicensed carrier whose monitoring result satisfies a first preset condition, or an unlicensed carrier whose measurement result satisfies a second preset condition, or an unlicensed carrier screen whose monitoring result satisfies the first preset condition and whose measurement result satisfies the second preset condition.

For example, the terminal listens to the 3 unlicensed carriers CZ, CW and CV, and the listening result is: in 10 monitoring of 3 unauthorized carriers closest to the current moment, the frequency of resource occupation is respectively 2 times, 3 times and 4 times, and no resource occupation is generated in the monitoring of 3 times closest to the current moment.

The first preset condition may be: in the 10 monitoring times closest to the current moment, the frequency of the resource occupation of the unlicensed carrier is less than 4 times, and in the 3 monitoring times closest to the current moment, the frequency of the resource occupation of the unlicensed carrier is less than 1 time.

Based on a first preset condition, the frequency of resource occupation of the unlicensed carriers CZ and CW in the last 10 monitoring is less than 4 times, and the frequency of resource occupation of the unlicensed carriers CZ and CW in the last 3 monitoring is less than 1 time.

Thus, the unlicensed carriers CZ and CW, which are available unlicensed carriers, satisfy the first preset condition.

According to the carrier determining method provided by the embodiment of the application, under the condition that the priority of the unlicensed carrier is higher than that of the licensed carrier, the available carrier is determined from the unlicensed carrier only by monitoring results and/or measuring results respectively corresponding to the unlicensed carriers, so that the cost for determining the available carrier is reduced.

Specifically, from the monitoring results corresponding to the most recent monitoring for several times, the number of times of resource occupation of the unlicensed carrier is considered, the number of times of resource occupation of the unlicensed carrier is not generated, the number of times of resource occupation of the unlicensed carrier continuously occurs, and the like, and the first preset condition is set based on the single aspect or the multiple aspects.

For example, the first preset condition may include: in M1 monitoring closest to the current moment, the frequency of the resource occupation of the unlicensed carrier is less than or equal to N1 times.

For example, the first preset condition may include: in the M2 monitoring times nearest to the current moment, the unauthorized carrier wave does not occupy the resources.

For example, the first preset condition may include: the number of times that the resource occupation occurs continuously on the unauthorized carrier closest to the current moment is less than or equal to N2 times.

The first preset condition can be set based on the single aspect or multiple aspects of the monitoring result monitored in a time window, considering the number of times of resource occupation of the unlicensed carrier, the number of times of resource occupation of continuous occurrence of the unlicensed carrier and the like.

For example, the first preset condition may include: and in a time window, the number of times of occupation of the monitored occurrence resources of the unauthorized carrier is less than or equal to N4 times.

For example, the first preset condition may include: during a time window, the unlicensed carrier is monitored for non-occurrence of resource occupancy.

For example, the first preset condition may include: and in a time window, the number of times of continuously-occurring resource occupation of the monitored unauthorized carrier is less than or equal to N7 times.

The first preset condition can be set based on the single aspect or multiple aspects of the latest monitoring for a plurality of times and monitoring in a time window, wherein the times of the resource occupation of the unlicensed carrier are considered, the times of the resource occupation of the unlicensed carrier are not considered, the times of the resource occupation of the continuous occurrence of the unlicensed carrier are considered, and the like.

For example, the first preset condition may include: during M2 monitoring times closest to the current moment, the unauthorized carrier wave does not occupy resources; and in a time window, the number of times of continuously-occurring resource occupation of the monitored unauthorized carrier is less than or equal to N7 times.

According to the carrier determination method provided by the embodiment of the application, from the latest monitoring results corresponding to monitoring in a plurality of times and/or a time window, the number of times of resource occupation of the unlicensed carrier continuously, and the like are considered, and the first preset condition is set based on the single aspect or the multiple aspects, so that the available unlicensed carrier can be accurately screened.

Specifically, the second preset condition may be set based on the RSSI measurement value, and the second preset condition may include: the RSSI measurement value corresponding to the unlicensed carrier is smaller than the first threshold.

For example, an unlicensed carrier corresponds to an RSSI measurement less than-100 dBm.

The second preset condition may be set based on the CO measurement value, and the second preset condition may include: the CO measurement corresponding to the unlicensed carrier is less than the second threshold.

For example, the unlicensed carrier corresponds to a CO measurement of less than 30%.

The second preset condition may be set based on the RSSI measurement value and the CO measurement value, and the second preset condition may include: the RSSI measured value corresponding to the unauthorized carrier is smaller than a first threshold; the CO measurement corresponding to the unlicensed carrier is less than the second threshold.

For example, an unlicensed carrier corresponds to an RSSI measurement of less than-100 dBm and an unlicensed carrier corresponds to a CO measurement of less than 30%.

According to the carrier wave determining method, the second preset condition is set in consideration of the RSSI measured value and/or the CO measured value, so that available unauthorized carrier waves can be accurately screened out.

Specifically, under the condition that the priority of the unlicensed carrier is higher than that of the licensed carrier, monitoring and/or measuring are performed on a plurality of unlicensed carriers, and monitoring results and/or measuring results corresponding to the plurality of unlicensed carriers are obtained.

And comparing the monitoring results respectively corresponding to the plurality of unauthorized carriers with a first preset condition, and comparing the measuring results respectively corresponding to the plurality of unauthorized carriers with a second preset condition. After comparison, the terminal finds that the unauthorized carrier wave with the monitoring result meeting the first preset condition and/or the measurement result meeting the second preset condition does not exist in the unauthorized carrier waves, and then measures the authorized carrier waves to obtain the measurement results corresponding to the authorized carrier waves.

The measurement of the plurality of licensed carriers may be CBR measurement of the licensed carriers, and the measurement result may be CBR values corresponding to the plurality of licensed carriers, respectively.

The licensed carrier availability condition may be a condition set based on the CBR value.

And comparing the measurement results respectively corresponding to the plurality of authorized carriers with the available conditions of the authorized carriers. After comparison, it is found that there are licensed carriers whose measurement results satisfy the conditions for the licensed carriers to be usable among the plurality of licensed carriers. And screening the authorized carrier wave with the measurement result meeting the authorized carrier wave availability condition, and determining the authorized carrier wave as an available authorized carrier wave.

According to the carrier determination method provided by the embodiment of the invention, when the priority of the unlicensed carrier is higher than that of the licensed carrier, and the unlicensed carrier with the monitoring result meeting the first preset condition and/or the measurement result meeting the second preset condition does not exist in the plurality of unlicensed carriers, the plurality of licensed carriers are measured, and the available carrier is determined from the licensed carriers, so that the cost for determining the available carrier is reduced.

In some embodiments, when the priority of the unlicensed carrier is higher than the priority of the licensed carrier, there are no unlicensed carriers whose monitoring results satisfy the first preset condition and/or the measurement results satisfy the second preset condition among the plurality of unlicensed carriers, and there are no licensed carriers whose measurement results satisfy the licensed carrier availability condition among the plurality of licensed carriers, the terminal temporarily does not determine the available carriers, continues to monitor and/or measure the unlicensed carriers first, and then measures the licensed carriers until the available unlicensed carriers or the available licensed carriers are obtained.

Specifically, fig. 5 is a third flow chart of the carrier determining method provided in the embodiment of the present application, and as shown in fig. 5, when the priority of the licensed carrier is higher than that of the unlicensed carrier, the terminal firstly measures a plurality of licensed carriers, and obtains measurement results corresponding to the plurality of licensed carriers respectively.

And comparing the measurement results corresponding to the plurality of authorized carriers with the authorized carrier availability conditions, screening the authorized carriers with the measurement results meeting the authorized carrier availability conditions, and determining the authorized carriers as available authorized carriers.

According to the carrier wave determining method provided by the embodiment of the application, under the condition that the priority of the authorized carrier wave is higher than that of the unauthorized carrier wave, the plurality of authorized carrier waves are measured first, and the available carrier waves are determined from the authorized carrier waves, so that the cost for determining the available carrier waves is reduced.

Specifically, under the condition that the priority of the authorized carrier is higher than that of the unauthorized carrier, the terminal firstly measures a plurality of authorized carriers to obtain measurement results corresponding to the authorized carriers respectively.

After comparison, the authorized carrier with the measurement result meeting the available condition of the authorized carrier does not exist in the plurality of authorized carriers, and the terminal monitors and/or measures the unauthorized carrier to acquire the monitoring result and/or the measurement result respectively corresponding to the plurality of unauthorized carriers.

And comparing the monitoring results respectively corresponding to the plurality of unauthorized carriers with a first preset condition, and comparing the measuring results respectively corresponding to the plurality of unauthorized carriers with a second preset condition.

And screening the unauthorized carrier wave with the monitoring result meeting the first preset condition and/or with the measuring result meeting the second preset condition, and determining the unauthorized carrier wave as the available unauthorized carrier wave.
