Description

Method for sending uplink information and user equipment

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a method for sending uplink information and a user equipment.

Background

In an NR (New Radio) air interface system, a carrier has a relatively large bandwidth, and some UEs (users) have a limited bandwidth capability, and can only transmit or receive control information and data in a part of the bandwidth of the carrier, while some UEs have a relatively large bandwidth capability, and can transmit or receive control information and data in the entire bandwidth of the carrier. The bandwidth capability of the UE as referred to herein refers to the maximum bandwidth that the UE can simultaneously receive or transmit data in the frequency domain. For example, some UEs have a bandwidth capability of 20 mhz and some UEs have a bandwidth capability of 5 mhz. For UEs with poor Bandwidth capabilities, in order to improve the frequency diversity performance of the user, the user may operate in a limited frequency band with good performance at different times, we call a limited frequency band a Bandwidth Part (BWP), that is, the UE may receive and transmit control information and data in different BWP at different times.

With the increasing explosion of users' demands for broadband wireless services and the increasing contradiction between scarce spectrum resources, mobile operators are beginning to consider unlicensed bands (also known as unlicensed bands) as a supplement to licensed bands. The third generation partnership project (3GPP,3rd Generation Partnership Project) has determined a scheme for efficient carrier aggregation through unlicensed band and licensed band, and effectively improves the utilization rate of the whole network spectrum without significantly affecting other technologies in the unlicensed band.

Unlicensed bands have generally been allocated for some other use, for example, radar or wireless fidelity of the 802.11 family (WiFi, wireless Fidelity). Thus, there is uncertainty in the interference level on the unlicensed band, which results in that the quality of service (QoS, quality of Service) of LTE transmissions is generally more difficult to guarantee, but the unlicensed band can also be used for data transmissions with low QoS requirements. Here, a Long-term Evolution (LTE) system of a secondary cell deployed on an unlicensed band is referred to as a licensed band assisted access (LAA, licensed Assisted Access) system. In the unlicensed band, how to avoid interference between the LAA system and other wireless systems such as radar or WiFi is a key issue. Carrier sensing (CCA) is a collision avoidance mechanism commonly employed on unlicensed bands. A mobile Station (STA) must detect a radio channel before transmitting a signal and can occupy the radio channel only when it detects that the radio channel is idle. LAA also follows a similar mechanism to ensure less interference with other signals. The LAA device (e.g., a base station or a user terminal) dynamically switches according to the carrier sense result, i.e., monitors that the channel is idle and transmits, and does not transmit if the channel is busy. In the LAA system, the bandwidth of the CCA performed by the UE is the bandwidth of the carrier, and the bandwidth capability of all UEs is equal to or greater than the bandwidth of the carrier, so that all UEs perform CCA over the entire bandwidth of the carrier.

In the NR system, the bandwidth capability of some UEs is greater than or equal to the bandwidth of the carrier, and the bandwidth capability of some UEs is less than the bandwidth of the carrier, so how to perform carrier sensing for different UEs is a problem to be solved in the system.

Detailed Description

In order to better understand the aspects of the present disclosure, the following description will clearly and completely describe the technical aspects of the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure.

In some of the flows described in the specification and claims of this disclosure and in the foregoing figures, a number of operations are included that occur in a particular order, but it should be understood that the operations may be performed in other than the order in which they occur or in parallel, that the order of operations such as 101, 102, etc. is merely for distinguishing between the various operations, and that the order of execution does not itself represent any order of execution. In addition, the flows may include more or fewer operations, and the operations may be performed sequentially or in parallel. It should be noted that, the descriptions of "first" and "second" herein are used to distinguish different messages, devices, modules, etc., and do not represent a sequence, and are not limited to the "first" and the "second" being different types.

The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of the disclosure.

Referring to fig. 1, a method 100 for transmitting uplink control information and data of the present disclosure includes the following steps:

in step 101, a frequency band for carrier sensing and an allocation manner of uplink frequency domain resources are determined by a receiving signaling or a protocol preset manner.

In step 102, carrier sensing is performed on the determined carrier sensing frequency band.

In step 103, when the carrier is idle, uplink information is sent on the uplink frequency domain resource determined according to the allocation mode of the uplink frequency domain resource.

Specifically, the UE determines whether to transmit uplink control information and data according to the carrier sense result. When the monitored carrier is busy, the UE does not send information; when the carrier is idle, the UE determines to transmit information on the uplink frequency domain resource according to the determined allocation manner of the uplink frequency domain resource, as shown in the specific flowchart for transmitting uplink information in fig. 2.

The signaling in step 101 above may include UE-specific higher layer signaling, as well as physical layer signaling, or a combination of higher layer signaling and physical layer signaling, or system information (e.g., master information block (MIB, master Information Block), or system information block (SIB, system Information Block) information). Physical layer signaling refers to information in downlink control information (DCI, downlink Control Information).

The allocation method of the uplink frequency domain resource in the above step 101 refers to a usage (or description) of the frequency domain resource allocation field in the DCI.

By way of illustration and not limitation, the frequency band in which carrier sensing is determined by the protocol preset manner may determine a fixed value by the protocol, for example, the protocol determines that the frequency band in which carrier sensing is performed is 5 mhz.

The method for transmitting uplink information of the present disclosure may be applied to a wireless communication system of a UE with limited bandwidth capability, and applied to a shared frequency band or an unlicensed frequency band, where carrier sensing is performed before the UE transmits uplink control information and data, and the UE may transmit the uplink control information and data only when the carrier is idle, and may not transmit the uplink control information and data if the carrier is busy, and the carrier sensing performed by the UE is performed in a certain frequency band, for example, the frequency band is 10 mhz, or 20 mhz.

The method of transmitting uplink information of the present disclosure is explained below by several embodiments. In order to reduce peak-to-average ratio, the uplink frequency domain resources in the present disclosure are allocated in an interleaved (interleaved) manner, that is, physical resource blocks (PRBs, physical Resource Block) with the same frequency domain interval in a frequency band are used as a resource allocation unit to perform resource allocation, for example, a frequency band includes 100 PRBs, 10 PRBs spaced from each other by 10 PRBs are used as a resource allocation unit, and 10 resource allocation units are shared, where the resource allocation unit i includes 10 PRBs respectively 10×i,10×i+1, 10×i+2, 10×i+3, 10×i+4, 10×i+5, 10×i+6, 10×i+7, 10×i+8, 10×i+9, where i=0, 1,2,3,4,5,6,7,8,9, and each UE may allocate one or more resource allocation units, as shown in fig. 3. The uplink transmission waveform may be DFT-S-OFDM.

The present embodiment describes that the UE determines the bandwidth of the carrier sense band and the position of the band (for example, the position of the band may be determined by the starting PRB of the band, or the center frequency of the band), and then may perform carrier sense, and decides whether to transmit uplink data according to the result of the carrier sense. The bandwidth of the carrier sense band may be in PRB number, for example, 100 PRBs and 50 PRBs, or may be directly in mhz, for example, 5 mhz and 20 mhz. The bandwidth of carrier sensing is the possible maximum bandwidth occupied by uplink control information and data transmitted by the UE each time, that is, the maximum bandwidth indicated by the frequency domain resource allocation field in the DCI of the scheduled physical uplink shared channel (PUSCH, physical Uplink Channel), and there are the following ways to determine the bandwidth and the band position of the carrier sensing band for the UE.

Pathway one:

in this embodiment, the UE determines the bandwidth of the frequency band in which the UE performs carrier sensing and the location of the frequency band by receiving the UE-specific higher layer signaling. For example, the bandwidth of the band for UE one performing carrier sensing is configured to be 5 mhz, the starting position of the 5 mhz bandwidth is configured to be the starting position of the whole carrier, the bandwidth of the band for UE two performing carrier sensing is configured to be 10 mhz, and the starting position of the 10 mhz bandwidth is configured to be the ending position of the 5 mhz bandwidth, as shown in fig. 4.

For UEs with different bandwidths of the frequency bands for carrier sensing, when the PUSCH is scheduled, the uplink frequency domain resource allocation manner may also be different, the number of bits of the frequency domain resource allocation field in the DCI for scheduling the PUSCH may be different, and in addition, the interpretation of the frequency domain resource allocation field may also be different. For example, UE one with a bandwidth of 5 mhz for a carrier sense, the frequency domain resource is divided into 25 PRBs, 5 PRBs spaced from each other by 5 PRBs are one frequency domain resource allocation unit, and there are 5 frequency domain resource allocation units in total, where the frequency domain resource allocation unit i includes 5 PRBs of 5×i,5×i+1,5×i+2,5×i+3,5×i+4, where i=0, 1,2,3,4, and each UE may allocate one or more frequency domain resource allocation units, as shown in fig. 5. If the bit mapping mode is adopted, the bit number of the frequency domain resource allocation field in the DCI is 5, and the value of each bit represents whether one frequency domain resource allocation unit is allocated or not. For example, UE two with a bandwidth of 10 mhz in the band of carrier sensing is divided into 50 PRBs, 10 PRBs spaced from each other by 5 PRBs are one frequency domain resource allocation unit, and there are 5 frequency domain resource allocation units in total, where the frequency domain resource allocation unit i includes 10 PRBs of 5×i,5×i+1,5×i+2,5×i+3,5×i+4, where i=0, 1,2,3,4, and each UE may allocate one or more frequency domain resource allocation units, as shown in fig. 6. If the bit mapping mode is adopted, the bit number of the frequency domain resource allocation field in the DCI is 5, and the value of each bit represents whether one frequency domain resource allocation unit is allocated or not.

According to the embodiment of the disclosure, under the condition that the bandwidth capabilities of the UE are different, the band bandwidths and the band positions for carrier sensing are determined through, for example, high-layer signaling, so that carrier sensing is performed according to the determined different bandwidths, unlicensed spectrum can be better utilized, larger throughput is provided for the UE, and particularly when the bandwidth capabilities of the UE are lower, a fixed band bandwidth is determined for the UE to perform carrier sensing.

Pathway two:

in this embodiment, the UE determines the bandwidth of the frequency band in which the UE performs carrier sensing by receiving UE-specific higher layer signaling. For example, the bandwidth of the band in which UE one performs carrier sensing is configured to be 5 mhz, and the bandwidth of the band in which UE two performs carrier sensing is configured to be 10 mhz. The UE determines the band location where the UE may perform carrier sensing by receiving UE-specific higher layer signaling or cell common higher layer signaling, and the determined band location where carrier sensing may be performed is at least one.

For example, the higher layer signaling configures 4 locations of a band in which UE may perform carrier sensing, as shown in fig. 7.

When the determined band location where the UE may perform carrier sensing is more than one, the UE determines the band location where the carrier sensing is performed by receiving physical layer signaling or medium access layer signaling.

For example, the UE may indicate the band location of carrier sensing by scheduling a new field in DCI of PUSCH, a redundant field, or other fields in reinterpreted DCI, referred to as a band indication field, and when configuring the band location of 4 carrier sensing, may indicate with a 2-bit band indication field, and a mapping between specific band indication field values and band locations is shown in table 1.

Table 1: mapping between band indication field values and band locations for carrier sensing

Alternatively, the frequency band position of the UE for carrier sensing may also be determined by scheduling the frequency domain resources allocated by the frequency resource allocation field in the DCI of the physical uplink shared channel (PUSCH, physical Uplink Shared Channel), and if all the frequency domain resources allocated to the UE are included in a frequency band configured by a higher layer signaling, the UE performs carrier sensing on the frequency band. For example, the higher layer signaling configures 4 locations of the band where the UE one may perform carrier sensing, and in the uplink slot n, the frequency resource allocated by the UE one is included in the band location two, and the UE one performs carrier sensing in the band location two, as shown in fig. 8.

According to the embodiment of the disclosure, under the condition that the bandwidth capabilities of the UE are different, the frequency band bandwidth for carrier sensing is configured through, for example, high-layer signaling, and the frequency band position for carrier sensing is configured through physical layer signaling, so that relatively flexible carrier sensing and better utilization of unlicensed spectrum are realized, larger throughput is provided for the UE, and the effect of frequency diversity can be achieved through configuring a plurality of frequency band positions for carrier sensing.

Pathway three:

in this embodiment, the UE determines the bandwidth of the frequency band and the location of the frequency band where the UE performs carrier sensing by receiving the physical layer signaling. The physical layer signaling here may be a field in DCI scheduling PUSCH; it may be a field in DCI that does not schedule PUSCH, i.e., a field in DCI that exclusively indicates the bandwidth of the frequency band and the location of the frequency band where the UE performs carrier sensing.

First, the UE determines the bandwidth of at least one frequency band in which the UE may perform carrier sensing within one BWP and the location of at least one possible frequency band of the bandwidth of each frequency band by receiving UE-specific higher layer signaling. For example, UE determines the bandwidths of the bands in which 4 UEs may perform carrier sensing by receiving UE-specific higher layer signaling, which are 40 mhz, 20 mhz, 10 mhz, and 5 mhz, respectively, and when the bandwidths of the bands performing carrier sensing are 40 mhz, the bandwidths of the bands have a possible location of the bands; when the bandwidth of the frequency band for carrier sensing is 20 megahertz, the bandwidth of the frequency band has two possible positions of the frequency band; when the bandwidth of the frequency band for carrier sensing is 10 megahertz, the bandwidth of the frequency band has four possible positions; when the bandwidth of the band in which carrier sensing is performed is 5 mhz, there are four possible locations of the bandwidth of the band, as shown in fig. 9. The UE determines the bandwidths of 2 frequency bands of which the UE is likely to perform carrier sensing by receiving UE specific high-layer signaling, wherein the bandwidths are respectively 20 MHz and 10 MHz, and when the bandwidth of the frequency band for performing carrier sensing is 20 MHz, the bandwidth of the frequency band has a possible position of the frequency band; when the bandwidth of the band in which carrier sensing is performed is 10 mhz, there are two possible locations of the bandwidth of the band, as shown in fig. 10.

When the bandwidths of the frequency bands to be monitored by the carrier are different, the intervals of the resource allocations in the frequency bands may also be different, the number of PRBs included in each frequency domain resource allocation unit may also be different, in order to occupy the bandwidths of the whole carrier, the intervals of the resource allocations are equal to the intervals of the resource allocations multiplied by the bandwidths in each frequency domain resource allocation unit, for example, the bandwidths of the frequency bands to be monitored by the carrier are 100 PRBs, the intervals of the resource allocations in the frequency bands are 10 PRBs, each frequency domain resource allocation unit contains 10 PRBs, and the total of 10 resource allocation units is 10 PRBs, as shown in the left diagram of fig. 11, the bandwidths of the frequency bands to be monitored by the carrier may also be 100 PRBs, and the intervals of the resource allocations in the frequency bands are 5 PRBs, and each frequency domain resource allocation unit includes 20 PRBs, and the total of 5 frequency domain resource allocation units, as shown in the right diagram of fig. 11. For example, if the bandwidth of the frequency band for carrier sensing is 50 PRBs and the interval of the intra-band resource allocation is 5 PRBs, each frequency domain resource allocation unit includes 10 PRBs, and there are 5 frequency domain resource allocation units in total.

For a band bandwidth of carrier sensing, the UE may preset and determine an interval of inter-band resource allocation in the band through a protocol, for example, when the bandwidth of the band of carrier sensing is 40 mhz, the UE includes 200 PRBs, and the interval of inter-band resource allocation in the band is 20 PRBs, and there are 20 resource allocation units in total; when the bandwidth of the frequency band monitored by the carrier is 20 MHz, the frequency band comprises 100 PRBs, the interval of the inter of the resource allocation in the frequency band is 10 PRBs, and the frequency band comprises 10 resource allocation units; the bandwidth of the frequency band monitored by the carrier is 10 MHz, and the bandwidth comprises 50 PRBs, the interval of the inter of the resource allocation in the frequency band is 5 PRBs, and the bandwidth is 5 resource allocation units in total; the bandwidth of the band for carrier sensing is 5 mhz, and the bandwidth includes 25 PRBs, and the interval of the intra-band resource allocation is 5 PRBs, and there are 5 resource allocation units, as shown in table 2.

Table 2: mapping between bandwidth and interval of carrier-sensed frequency band

For a band bandwidth of carrier sensing, the UE may also determine an interval of resource allocation in the band by receiving higher layer signaling, for example, when the bandwidth of the carrier sensing band is 40 mhz, the UE includes 200 PRBs, the interval of resource allocation in the band is 20 PRBs, and there are 20 resource allocation units in total; when the bandwidth of the frequency band monitored by the carrier is 20 MHz, the frequency band comprises 100 PRBs, the interval of the inter of the resource allocation in the frequency band is 10 PRBs, and the frequency band comprises 10 resource allocation units; the bandwidth of the frequency band monitored by the carrier is 10 MHz, and the bandwidth comprises 50 PRBs, the interval of the inter of the resource allocation in the frequency band is 5 PRBs, and the bandwidth is 5 resource allocation units in total; the bandwidth of the band for carrier sensing is 5 mhz, and the bandwidth includes 25 PRBs, and the interval of the intra-band resource allocation is 5 PRBs, and there are 5 resource allocation units, as shown in table 2.

According to the embodiment of the disclosure, under the condition that the bandwidth capabilities of the UE are different, the bandwidth and the band position for carrier sensing are flexibly configured through the combination of, for example, high-layer signaling and physical layer signaling, so that flexible carrier sensing and better utilization of unlicensed spectrum are realized, and larger throughput is provided for the UE.

When the UE determines that the UE has more than one bandwidth for the UE to perform carrier sensing within one BWP by receiving the UE-specific higher layer signaling, the UE dynamically selects one bandwidth from the plurality of bandwidths configured for the UE to perform carrier sensing by the higher layer signaling by receiving the physical layer signaling to determine the bandwidth as the bandwidth for the UE to perform carrier sensing, which may be determined in the following ways.

Mode one:

in this embodiment, the physical layer signaling may be an independent field in the DCI for scheduling PUSCH, a bandwidth indicating field called a band, or the physical layer signaling may be a field in the DCI for scheduling PUSCH, but not a field in a specific DCI, a bandwidth indicating field called a band, for indicating the bandwidth of the band for carrier monitoring, for example, the UE may determine that there may be 4 bandwidths of the band for the UE to perform carrier monitoring by receiving the UE-specific higher layer signaling, and the bandwidth indicating field of the band may be 40 mhz, 20 mhz, 10 mhz, 5 mhz, respectively, and the bandwidth indicating field of the band may be 2 bits, and the 2 bits may be a newly added field in the DCI, or may be a redundant field in the DCI, or may be a field in which the other fields in the DCI are reinterpretated, and the mapping between the bandwidth indicating field value of the specific band and the bandwidth of the band is shown in table 3. The UE determines the bandwidth of the frequency band of the UE for carrier sensing by receiving the physical layer signaling, and the frequency domain resource allocation method is determined according to the relationship between the bandwidth of the frequency band of the UE for carrier sensing and the frequency domain resource allocation method, where the frequency domain resource allocation method includes an interval, the number of PRBs of each resource allocation unit, and the number of resource allocation units, for example, according to the relationship between the bandwidth of the frequency band of the UE for carrier sensing and the frequency domain resource allocation method in table 2.

Table 3: mapping between bandwidth indication field value of frequency band and bandwidth of frequency band

Bandwidth indication field value of a frequency band	Bandwidth of frequency band (megahertz)

01	20
		10	10
11	5

By using the method, carrier sensing can be performed according to the bandwidth required by the data, and the opportunity of the UE to utilize the unlicensed spectrum can be improved.

Mode two:

in this embodiment, this physical layer signaling may be a joint coding indication of the bandwidth of the band indicating carrier sensing and other fields in the DCI of the scheduled PUSCH, for example, a joint coding field indicating the bandwidth of the band indicating carrier sensing and frequency domain resource allocation, which is used to indicate the bandwidth of the band indicating carrier sensing and allocation of frequency domain resources, referred to as a bandwidth indication of the band and frequency domain resource allocation field, where different ranges of values represent bandwidths of different bands of carrier sensing.

For example, upon receiving UE-specific higher layer signaling, UE determines bandwidths of the frequency bands where the 4 UEs may perform carrier sensing, which are respectively 40 mhz, 20 mhz, 10 mhz, 5 mhz, the bandwidth indication of the frequency band and the frequency domain resource allocation field are N bits, the bandwidth indication of the frequency band and the frequency domain resource allocation field are denoted as L, and the specific bandwidth indication of the frequency band and the mapping between the frequency domain resource allocation field value and the bandwidth of the frequency band are shown in table 4. The UE determines the bandwidth of the frequency band of the UE for carrier sensing by receiving the physical layer signaling, and the frequency domain resource allocation method is determined according to the relationship between the bandwidth of the frequency band of the UE for carrier sensing and the frequency domain resource allocation method, where the frequency domain resource allocation method includes an interval, the number of PRBs of each resource allocation unit, and the number of resource allocation units, for example, according to the relationship between the bandwidth of the frequency band of the UE for carrier sensing and the frequency domain resource allocation method in table 2.

When the UE determines that there is more than one possible carrier-sensing possible band within one BWP by receiving UE-specific higher layer signaling when there are multiple possible band locations of the bandwidth of the carrier-sensing possible band, the UE dynamically selects one determined carrier-sensing possible band location for the UE from among the multiple possible carrier-sensing possible band locations configured for higher layer signaling by receiving physical layer signaling. There may be several ways.

Mode one:

in this embodiment, the physical layer signaling may be an independent field in DCI for scheduling PUSCH, a location indicating field called a band for indicating a location of a band where the UE performs carrier sensing, or may be a field in DCI for scheduling PUSCH, but a field in dedicated DCI for indicating a location of a band where the carrier sensing is performed, and may be a location indicating field called a band, for example, when UE determines that when the bandwidth of the band performing carrier sensing is 5 mhz by receiving UE-specific higher layer signaling, there are locations of the band where the 4 UEs may perform carrier sensing, respectively, a location one of the band, a location two of the band, a location three of the band, and a location four of the band, and the location indicating field of the band is 2 bits, and this 2 bits may be a newly added bit in DCI, or may be a redundant bit in DCI, or may be another field in reinterpretation, and mapping between a location indicating field value of a specific band and a location of the band is shown in table 5. The UE determines the position of the frequency band where the UE performs carrier sensing by receiving the physical layer signaling, and the frequency domain resource allocated to the frequency domain resource is determined according to the position of the frequency band where the UE performs carrier sensing, where the allocated frequency domain resource is included in the frequency band of the position of the frequency band, and as shown in fig. 12, the position of the frequency band where the UE performs carrier sensing is the position of the frequency band two, and the allocated frequency domain resource is included in the frequency band of the position of the frequency band two.

Table 5: mapping between the location indication field value of a frequency band and the location of the frequency band

Location indication field value of frequency band	Location of frequency bands
		00	Position one of frequency band
01	Second position of frequency band
		10	Position three of frequency band
11	Location four of frequency band

When the UE-specific higher layer signaling is received to determine that the bandwidth of the band for carrier sensing is 20 mhz, there are 2 locations of the band where the UE may perform carrier sensing, that is, the location one of the band, the location two of the band, and the location indication field of the band are 1 bit, and this 1 bit may be a new bit in the DCI, or may be a redundant bit in the DCI, or may be another field in the DCI, and the mapping between the specific location indication field value of the band and the location of the band is shown in table 6. The UE determines the position of the frequency band where the UE performs carrier sensing by receiving the physical layer signaling, and the position of the frequency domain resource allocation is determined according to the position of the frequency band where the UE performs carrier sensing, where the position of the frequency domain resource is included in the position of the frequency band.

By using the method, a plurality of frequency band positions for carrier sensing are configured, so that the effect of frequency diversity can be achieved.

1	Second position of frequency band

Mode two:

in this embodiment, the physical layer signaling may be a joint coding indication of a position of a frequency band indicating carrier sensing and other fields in DCI for scheduling PUSCH, for example, a joint coding field indicating a position of a frequency band indicating carrier sensing and frequency domain resource allocation, which is used to indicate a position of a frequency band and allocation of frequency domain resources, which are called a position indication of a frequency band and a frequency domain resource allocation field.

The bandwidth of the frequency band of the carrier monitoring by the UE is dynamically obtained through receiving the indication in the DCI for scheduling the PUSCH by the UE, so that the number of bits of the DCI for scheduling the bandwidths of different frequency bands needs to be kept consistent, the DCI for scheduling the PUSCH can be blindly checked according to the determined number of bits of the DCI, the blind check number is reduced, and if the bandwidth indication field of the frequency band in the DCI is an independent field, the UE obtains the bandwidth by receiving the bandwidth indication field of the frequency band in the DCI, and then obtains the position of the frequency band of the carrier monitoring and the frequency domain resource allocation according to the format of the joint coding field of the frequency band of the carrier monitoring and the frequency domain resource allocation under the condition of the obtained bandwidth, and under the condition of different bandwidths, the position of the frequency band of the carrier monitoring and the number of bits required by the joint coding field of the frequency domain resource allocation may be different, and the filling bits are required to make the bandwidth of the frequency band of the carrier monitoring different, and the number of bits of the DCI for scheduling the PUSCH is the same.

As shown in fig. 13, the UE first receives DCI for scheduling PUSCH; then the band bandwidth of carrier monitoring is determined by reading the band bandwidth indication field; determining a format of a band location and frequency domain resource allocation joint coding field according to the determined band bandwidth for carrier sensing; determining a band location according to the format; and determining the allocated frequency domain resources.

For example, UE-specific higher layer signaling is received to determine the bandwidths of the frequency bands where 4 UEs may perform carrier sensing, which are 40 mhz, 20 mhz, 10 mhz, 5 mhz, respectively, and the bandwidth indication of the frequency bands requires 2 bits.

When the bandwidth of the band monitored by the carrier is 40 megahertz, the band comprises 200 PRBs, the interval of the inter of the resource allocation in the band is 20 PRBs, and the band comprises 20 resource allocation units, and the frequency resource allocation needs to: the upper rounding (log 2 (20×20+1)/2))=8 bits, and there is one band position available for the UE to perform carrier sensing, so that no indication of the position of the band sensed by the carrier is needed, and the number of bits in the joint coding field of the position and frequency domain resource allocation of the band sensed by the carrier is 8 bits.

When the bandwidth of the band monitored by the carrier is 20 megahertz, the band comprises 100 PRBs, the interval of the inter of the resource allocation in the band is 10 PRBs, and the band comprises 10 resource allocation units, and the frequency resource allocation needs to: the upper rounding (log 2 (10×10+1)/2))=6 bits, and there are two band positions available for the UE to perform carrier sensing, and the position indication of the band requiring 1 bit carrier sensing is indicated, and the number of bits in the joint coding field of the position and frequency domain resource allocation of the band of carrier sensing is 6+1=7 bits.

When the bandwidth of the band monitored by the carrier is 10 megahertz, the band comprises 50 PRBs, the interval of the inter of the resource allocation in the band is 5 PRBs, and the band is divided into 5 resource allocation units, and the frequency resource allocation needs to: the upper rounding (log 2 (5×5+1)/2))=4 bits, and there are four band positions available for the UE to perform carrier sensing, and the position indication of the band requiring 2 bits carrier sensing is indicated, and the number of bits in the joint coding field of the position and frequency domain resource allocation of the band of carrier sensing is 4+2=6 bits.

When the bandwidth of the frequency band of the carrier sense is 5 mhz, the frequency band comprises 25 PRBs, the interval of the inter of the resource allocation in the frequency band is 5 PRBs, and the total of the 5 resource allocation units is 5, and the frequency resource allocation needs to: the upper rounding (log 2 (5×5+1)/2))=4 bits, and there are four band positions available for the UE to perform carrier sensing, and the position indication of the band requiring 2 bits carrier sensing is indicated, and the number of bits in the joint coding field of the position and frequency domain resource allocation of the band of carrier sensing is 4+2=6 bits.

In order to ensure that the bit number of the DCI of the scheduling PUSCH is the same when the bandwidths of the frequency bands monitored by different carriers are different, when the bandwidth of the frequency band monitored by the carrier is 40 MHz, the bit number of the joint coding field of the position and the frequency domain resource allocation of the frequency band monitored by the carrier is 8 bits; when the bandwidth of the frequency band monitored by the carrier is 20 MHz, the bit number required by the joint coding field of the position and the frequency domain resource allocation of the frequency band monitored by the carrier is 7 bits, and 1 bit of filling bit is added for 8 bits in total; when the bandwidth of the frequency band monitored by the carrier is 10 MHz, the bit number required by the joint coding field of the position and the frequency domain resource allocation of the frequency band monitored by the carrier is 6 bits, and 2 bits of filling bits are added for 8 bits in total; when the bandwidth of the carrier-monitored frequency band is 5 mhz, the number of bits required for the joint coding field of the position and frequency domain resource allocation of the carrier-monitored frequency band is 6 bits, and 2 bits are added to fill 8 bits, so that the total number of bits of the DCI is unchanged regardless of the bandwidth of the carrier-monitored frequency band, and the blind detection times of the DCI can be reduced.

By using the user equipment UE of the embodiment of the disclosure, under the condition that the bandwidth capabilities of the UE are different, the unlicensed spectrum can be better utilized by dynamically changing the bandwidth of the CCA, and a larger throughput is provided for the UE.

The present embodiment describes a method for determining a downlink reception state during BWP handover.

The downlink receiving state includes: a Wake-Up Signal (WUS) detection state, a PDCCH detection state, and a stop detection state, wherein the PDCCH detection state includes a PDCCH detection state of type a and a PDCCH detection state of type B, and the stop detection state refers to a state in which WUS is not detected and PDCCH is not detected, which will be described later.

WUS is a type of reference signal provided for reducing implementation complexity of a UE and saving power consumption for the UE. In an exemplary embodiment, the UE starts to detect the PDCCH after detecting the WUS, so that unnecessary PDCCH detection can be reduced, and detecting the WUS saves power compared to detecting the PDCCH, so that the purpose of reducing the implementation complexity of the UE and saving power consumption for the UE can be achieved by using the WUS.

Since the time when the carrier sensing result is idle is random, which may not be at the beginning of the time slot, in order to fully utilize the downlink resource, the UE should detect the PDCCH with a smaller time period (referred to as type B PDCCH detection, e.g., detecting the PDCCH with 2 OFDM symbols as a period) immediately after the UE receives the WUS, which may reduce the time when the carrier sensing result is idle and the interval at which the UE receives the PDCCH, thereby being able to receive data using the resource as soon as possible. After a certain time, since there is no need for low-latency traffic transmission in the unlicensed frequency band, the UE should detect the PDCCH with a larger time period (referred to as type a PDCCH detection, e.g., detecting the PDCCH with one slot as a period), which can save power consumption for the UE and also save resources occupied by the PDCCH.

If the UE configures WUS detection, PDCCH detection of type B, PDCCH detection of type a, and stop detection state, the UE may be in one of four downlink reception states, WUS detection state, PDCCH detection state of type B, PDCCH detection state of type a, and stop detection state. If the UE is configured with WUS detection, PDCCH detection, the UE may be in one of two downlink reception states, WUS detection state, PDCCH detection state. If the UE configures PDCCH detection of type B, PDCCH detection of type a, the UE may be in one of two downlink reception states, i.e., a PDCCH detection state of type B, a PDCCH detection state of type a.

For transmission in an unlicensed band, in order to reduce interference to WIFI systems, a device occupies a channel that cannot always occupy the channel, and a maximum occupied channel time is defined as a channel occupied time (COT, channel Occupancy Time). For unpaired spectrum, i.e. one spectrum, there may be either uplink (UE transmitting data, base station receiving data) or downlink (base station transmitting data, UE receiving data). Within a COT there may be a downlink transmission and an uplink transmission, and then a downlink transmission and then an uplink transmission, where a switching point is between the downlink transmission and the uplink transmission, and there may be only one switching point in a COT, as shown in fig. 15.

When the UE configures multiple downlink BWP, the active downlink BWP of the UE dynamically switches from one downlink BWP to another downlink BWP, wherein a manner of the active downlink BWP switching is determined by a manner of a Timer (Timer), and when the Timer expires (expire), the active downlink BWP of the UE switches from the current active downlink BWP to another downlink BWP (e.g., default downlink BWP), which is denoted as BWP-switchTimer. The downlink reception state of the current active downlink BWP of the UE determines BWP-switchTimer value, that is, the downlink reception state of the current active downlink BWP of different UEs adopts different BWP-switchTimer values, for example, when the downlink reception state of the current active downlink BWP of the UE is WUS detection state, the BWP-switchTimer value is BWP-switchTimer-1, that is, when the timer BWP-switchTimer-1 expires, the UE switches from the current active downlink BWP to another downlink BWP; the downlink reception state of the current active downlink BWP of the UE is PDCCH detection, and the BWP-switchTimer value is BWP-switchTimer-2, that is, after the timer BWP-switchTimer-2 expires, the UE switches from the current active downlink BWP to another downlink BWP, or the UE switches from the current active downlink BWP to another downlink BWP after the COT where the current active downlink BWP is located ends and the timer BWP-switchTimer-2 expires. When the downlink receiving state of the UE currently activating the downlink BWP is the WUS detection state, which indicates that the base station performs carrier sensing on the downlink BWP, when the carrier sensing result of the base station is idle, the base station may send WUS, and the UE may not receive WUS, which may be that the interference suffered by the BWP is serious, so that the UE needs to switch to another downlink BWP to receive WUS, and the interference suffered by another downlink BWP may not be serious, which improves the working opportunity of the UE. When the downlink reception state of the currently active downlink BWP of the UE is the PDCCH detection state, it indicates that the result of carrier sensing performed by the base station on the downlink BWP is idle, and the UE does not receive the PDCCH for a long time, which may be that the base station instructs the UE to switch to another downlink BWP, and the UE does not receive the instruction, the UE and the base station understand the active downlink BWP differently, so that the UE and the base station understand the active downlink BWP equally, and the UE switches to a default downlink BWP to detect the PDCCH. Therefore, it is advantageous to determine an independent BWP-InactivityTimer value based on the downlink reception state of the UE currently activating downlink BWP.
