Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
The terms "first," "second," and the like in this application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Further, as used herein, "and/or" means at least one of the connected objects, e.g., a and/or B and/or C, means 7 cases including a alone, B alone, C alone, and both a and B present, B and C present, both a and C present, and A, B and C present.
Referring to fig. 1, fig. 1 is a structural diagram of a network system to which an embodiment of the present invention is applicable, and as shown in fig. 1, the network system includes a terminal 11 and a network-side device 12, where the terminal 11 and the network-side device 12 can communicate with each other.
In the embodiment of the present invention, the terminal 11 may also be referred to as a User Equipment (UE). In practical applications, the terminal 11 may be a mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a laptop Computer (laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device. The network side device 12 may be a base station, a relay, an access point, or the like.
For convenience of understanding, some contents related to the embodiments of the present invention are explained below:
in the NR unlicensed band, before sending information, the terminal or the network side device needs to perform LBT. Specifically, the terminal or the network side device needs to perform CCA or eCCA to listen to the channel, that is, perform ED, and when the energy is lower than a certain threshold, the channel is determined to be empty, so that the terminal or the network side device can start transmission. Since the unlicensed frequency band is shared by multiple technologies or multiple transmission nodes, the contention-based access method causes uncertainty of Available time of a Channel, and when the Channel is Available (Available), a transmittable location of a network-side device signal transmission may have been missed and cannot be transmitted, which may cause a receiving end to be unable to normally receive signal reception configured by the network side, and a terminal behavior performed according to the configuration of the network side after the signal reception, such as Physical Downlink Control Channel (PDCCH) monitoring, monitoring and measuring of a wireless environment, and the like. The process of determining whether a channel is empty and transmitting through a CCA mode may be referred to as a channel access process.
Is currently clearly available in the fifth generation (5)thGeneration, 5G) there are three types of channel access procedures for unlicensed communication systems:
cat 1 does not make any CCA direct transmission, but must be available in the case where the channel has been acquired with an interval of transmission transition less than 16 microseconds (us);
cat 2(Type II) that performs channel sensing of 16us or 25us, that can be used for a specific signal acquisition channel, and that the maximum continuous transmission length should be less than a certain value, for example, 1 millisecond (ms);
cat 4(Type I) carries out channel interception of random backspacing, different priority parameters are set, and finally, the maximum length which can be transmitted after obtaining the channel is different.
The COT indication method in License Assisted Access (LAA)/Enhanced licensed Assisted Access (eLAA)/Further Enhanced licensed Assisted Access (Further Enhanced LAA) is disclosed.
The terminal of LAA/eLAA/FeLAA monitors DCI format 1C scrambled by CC-RNTI in a control time region of each Subframe (Subframe) to acquire COT related information.
The Subframe configuration for LAA field of the Downlink Control Information (DCI) format (format)1C may indicate the Downlink symbol occupancy of the current Subframe or the next Subframe. The indication may be used to implement a function in which the COT end subframe is a Partial subframe. Meanwhile, if no DCI format 1C is detected in the subframe n-1, and the number of DCI display current DL symbols detected in the subframe n is less than 14, the terminal monitors the PDCCH or the ePDCCH only in the subframe.
The uplink duration and offset (UL duration and offset) field of the DCI format 1C may indicate which subframes are uplink transmissions in the COT time. On these subframes, the terminal does not need to monitor any downlink signals.
The base station can indicate the uplink subframe dynamically scheduled in the COT through the domain, and can update the channel access type indicated by the original ULgrant;
the base station may indicate that Autonomous Uplink (AUL) transmission may use Type 2 Channel Access (Channel Access) through the domain and an Autonomous uplink Channel occupied time Sharing (AUL Sharing) domain, that is, share the COT. The base station can set the domain to True only after acquiring the channel using the lowest priority Cat 4.
Second, a Slot Format Indication (SFI) Indication method in NR Rel 15.
In NR Rel15, flexible configuration is performed by combining semi-static (RRC configuration) radio resource control and dynamic downlink control information configuration.
DCI format 2_0 is specifically used as an SFI indication, and may configure SFI on multiple serving cells (serving cells), that is, multiple SFI indication (Indicator) fields, where the start bit position of the SFI Indicator field corresponding to each serving cell is indicated in the RRC. For a single slot, the maximum number of formats supported by NR Rel15 is 256, including each symbol indicating a slot as d (downlink), u (uplink), or f (flexible). For each serving cell, the base station may configure multiple slot formats (maximum 512) through RRC, and each slot format may indicate a format of 1-256 slots.
The symbol allocated as U by the SFI shall not be used for reception of other DCI format scheduling for PDSCH or CSI-RS; the symbol allocated by SFI as D should not be scheduled by other DCI formats for transmission of PUSCH, PUCCH, PRACH or SRS. The SFI indicates a flexible symbol, and the PDSCH or CSI-RS may be received by DCI scheduling, or the PUSCH, PUCCH, PRACH, or SRS may be transmitted by DCI scheduling.
The method of indicating COT according to the embodiment of the present invention will be described below.
Referring to fig. 2, fig. 2 is a flowchart of a method for indicating COT according to an embodiment of the present invention. The method for indicating the channel occupation time COT is applied to the terminal.
As shown in fig. 2, the method for indicating the channel occupancy time COT applied to the terminal may include the following steps:
step 201, receiving first indication information, where the first indication information is used to indicate related information of a first COT.
Wherein the relevant information comprises at least one of: the transmission state of the time domain resource of the first COT, the ending time domain resource of the first COT, and the identification information of the first COT.
In a specific implementation, the first Indication information may be Downlink Control Information (DCI) or a Slot Format Indication (SFI), and the specific representation form of the first Indication information is not limited in the present invention.
The time unit of the time domain resource may be a subframe, a Slot (Slot), or a Symbol (Symbol), and may be determined specifically according to actual requirements, which is not limited in the embodiment of the present invention.
For convenience of understanding, the following descriptions of the information items that the related information may contain are respectively as follows:
first, a transmission state of a time domain resource of the first COT.
Optionally, the transmission status of the time domain resource may include at least one of: uplink transmission, target downlink transmission and flexible transmission.
It should be noted that the transmission states of different time domain resources in the first COT may be the same or different. If the transmission state of the time domain resource 1 in the first COT is uplink transmission, the transmission states of the time domain resource 2 and the time domain resource 3 in the first COT are target downlink transmission, and the transmission state of the time domain resource 4 in the first COT is flexible transmission.
In the present embodiment, if the transmission state of a certain time domain resource is uplink transmission, it indicates that the time domain resource needs to transmit an uplink Signal and/or an uplink Channel, for example, transmission of a Physical Uplink Shared Channel (PUSCH), transmission of a Sounding Reference Signal (SRS), transmission of a PUCCH, transmission of a Physical Random Access Channel (PRACH), and the like.
If the transmission state of a certain time domain resource is the target Downlink transmission, it indicates that the time domain resource needs to monitor a Downlink signal and/or a Downlink Channel, such as Physical Downlink Control Channel (PDCCH) monitoring, reference signal monitoring, and the like.
If the transmission state of a certain time domain resource is flexible transmission, the specific function of the time domain resource needs to be determined by combining the position of the time domain resource in the first COT, which is specifically described as follows:
if the time domain resource is located between the fifth time domain resource and the sixth time domain resource of the first COT, the time domain resource may be regarded as a converted time domain resource, and the time domain resource does not need to be: sending an uplink signal and an uplink channel, and monitoring a downlink signal and a downlink channel.
If the time domain resource is not located between the fifth time domain resource and the sixth time domain resource of the first COT, the time domain resource may be considered as a resource to be scheduled, and the transmission state of the time domain resource may be switched to target downlink transmission or uplink transmission.
Wherein the transmission states of the time domain resources between the fifth time domain resource and the sixth time domain resource are both flexible transmission; and the transmission states of the fifth time domain resource and the sixth time domain resource are target downlink transmission and uplink transmission respectively. It should be noted that the fifth time domain resource may be before the sixth time domain resource or after the sixth time domain resource.
For ease of understanding, examples are illustrated below:
it is assumed that the first COT includes consecutive symbol 1, symbol 2, symbol 3, symbol 4, symbol 5, and symbol 6, and the transmission state of symbol 1 is downlink transmission, the transmission states of symbol 2 and symbol 3 are flexible transmission, the transmission state of symbol 4 is uplink transmission, the transmission state of symbol 5 is flexible transmission, and the transmission state of symbol 6 is uplink transmission. If the target downlink transmission is D, the flexible transmission is F, and the uplink transmission is U, the transmission states of symbol 1, symbol 2, symbol 3, symbol 4, symbol 5, and symbol 6 are DFFUFU in sequence.
For the symbol 2 and Slo3 in the F state, since they are located between the symbol 1 in the D state and the symbol 4 in the U state, they can be regarded as conversion symbols, and the transmission of the uplink signal and the uplink channel and the listening of the downlink signal and the downlink channel are not performed.
For the symbol 5 in the F state, since it is located between the symbol 4 in the U state and the symbol 6 in the U state, it can be regarded as a symbol to be scheduled, and can be switched to the D state or the U state.
In this embodiment, further, the target downlink transmission may include at least one of the following: first downlink transmission and second downlink transmission.
The time domain resource with the transmission state of the first downlink transmission is different from the time domain resource with the transmission state of the second downlink transmission in that: the time domain resource of the first downlink transmission in the transmission state can be monitored by a downlink channel, and the time domain resource of the second downlink transmission in the transmission state can not be monitored by the downlink channel. However, the time domain resource in the first downlink transmission and the time domain resource in the second downlink transmission may be monitored by the downlink signal.
In this embodiment, optionally, the first indication information may indicate a transmission state of the time domain resource of the first COT through a bitmap.
In a specific implementation, the first indication information may indicate a transmission state of the time domain resource of the first COT in the following two manners.
First mode
In the first manner, each bit group in the bitmap may correspond to one time domain resource in the first COT, and each bit group is used to indicate a transmission status of its corresponding time domain resource. Wherein, the time domain resources corresponding to different bit groups are different.
Different values of the bit groups may be used to indicate different transmission states. The group of bits comprises bits related to the number of transmission states.
Such as: the transmission state includes four kinds, and the bit group may include two bits. Illustratively, a bit group with a value of 00 may indicate that the transmission state of the corresponding time domain resource is uplink transmission, a bit group with a value of 01 may indicate that the transmission state of the corresponding time domain resource is first downlink transmission, a bit group with a value of 10 may indicate that the transmission state of the corresponding time domain resource is second downlink transmission, and a bit group with a value of 11 may indicate that the transmission state of the corresponding time domain resource is flexible transmission.
In the first mode, each bit group is used to indicate the transmission state of the corresponding time domain resource, so that the terminal may directly obtain the transmission state of the time domain resource of the first COT based on the bitmap.
Second mode
In the second mode, the association relationship between the transmission state of the time domain resource group and the index number is configured in advance, and in the association relationship, the transmission states of the time domain resource groups corresponding to different index numbers are different. Therefore, each bit group in the bitmap may correspond to one time-domain resource group in the first COT, and each bit group indicates an index number corresponding to its corresponding time-domain resource group.
The number of time domain resources included in a time domain resource group is determined based on a time unit of the time domain resources, and optionally, in a case that the time unit of the time domain resources is a symbol, one time domain resource group may include 14 symbols, that is, one time domain resource group constitutes one Slot.
The transmission state of the time-domain resource group is used for indicating the transmission state of each time-domain resource included in the time-domain resource group. Such as: under the condition that one time domain resource group can comprise 14 symbols, if the transmission state of the time domain resource group is ddddddffffuuu, it indicates that the transmission states of the first 4 symbols of the time domain resource group are both target downlink transmission, the transmission states of the 5 th symbol to the 10 th symbol of the time domain resource group are both flexible transmission, and the transmission states of the last 4 symbols of the time domain resource group are both uplink transmission.
Different values of the groups of bits may be used to indicate different index numbers. The groups of bits comprise bits related to the number of index numbers.
Such as: if the number of the index numbers is 256, that is, the transmission state of 256 time-domain resource groups is preset, each bit group may include 8 bits. Illustratively, the index number corresponding to the bit group with the value of 00000000 is 1, the index number corresponding to the bit group with the value of 00000001 is 2, and so on.
In the second mode, each bit group indicates the index number corresponding to the corresponding time domain resource group, so that after acquiring the index number corresponding to a certain time domain resource group, the terminal needs to search the association relationship to determine the transmission state of each time domain resource in the time domain resource group.
Each bit group does not include the same bits, and each bit group includes consecutive bits. It should be noted that, in the present embodiment, the bit groups are only used for convenience of description, and the representation form of the bit map is not limited thereby.
For ease of understanding, examples are illustrated below:
assume that the first COT includes two consecutive slots: slot1 and Slot2, each Slot comprising 14 symbols, note Slot1 comprising symbols 1 through 8 and Slot comprising symbols 9 through 16. The transmission states from symbol 1 to symbol 8 are dffuuuu in sequence, and the transmission states from symbol 9 to symbol 16 are DFFDDDDD in sequence. In addition, the time unit of the time domain resource is Slot.
In the first mode, it is assumed that the transmission states are 4, each bit group needs to include two bit bits, and a bit group with a value of 00 may indicate that the transmission state of the corresponding time domain resource is U, a bit group with a value of 01 may indicate that the transmission state of the corresponding time domain resource is D, and a bit group with a value of 11 may indicate that the transmission state of the corresponding time domain resource is F.
The bitmap requires 32 bits to indicate the transmission status of each time domain resource in the first COT. Under the condition that 32 bits sequentially indicate a symbol 1 to a symbol 16, values of the 32 bits sequentially are as follows: 01111100000000000111110101010101.
in the second mode, assuming that the number of index numbers is 256, each bit group needs to include 8 bits. The index number corresponding to the bit group whose value is 00000000 is 1, and the index number corresponding to the bit group whose value is 00000001 is 2. In the above association relationship, the transmission state of the time-domain resource group corresponding to the index number 1 is dffuuuu, and the transmission state of the time-domain resource group corresponding to the index number 2 is DFFDDDDD.
The bitmap requires 16 bits to indicate the transmission status of each time domain resource in the first COT. Under the condition that 16 bits sequentially indicate a symbol 1 to a symbol 16, values of the 16 bits sequentially are as follows: 0000000000000001.
it can be seen that in some cases, the bits required in the second mode are less than those required in the first mode, and in these cases, the signaling overhead can be reduced by using the second mode to indicate the transmission state of the time domain resource in the first COT.
And II, ending time domain resources of the first COT.
In this embodiment, in a specific implementation, the first indication information may indicate the ending time domain resource of the first COT in a plurality of ways, which is specifically described as follows:
in a first mode, the first indication information indicates: offset time information of the ending time domain resource relative to a first reference time, where the first reference time is: a time at which the first indication information is detected.
In a first manner, the first indication information indirectly indicates the ending time domain resource of the first COT by indicating the offset time information. In this way, the terminal may determine the location of the ending time domain resource in combination with the first reference time and the offset time information.
In a specific implementation, the specific expression of the offset time information may be determined based on the first reference time and the time unit of the time domain resource, and the present invention is not limited thereto.
Optionally, in a case that the time unit of the first reference time is Slot and the time unit of the time domain resource is Symbol, the Offset time information may include a Slot Offset (Offset) and a Symbol Index (Index) of the end time domain position relative to the first reference time.
For example, assume that Slot1, Slot2, Slot3, and Slot4 are 4 consecutive slots. The terminal detects the first indication information at Slot1, the Slot Offset is 3 slots, the Symbol Index indicates the 3 rd Symbol of the Slot, and the position of the ending time domain resource is the 3 rd Symbol of the Slot 4.
In a second mode, the first indication information indicates: the remaining time information of the first COT relative to a second reference time, where the second reference time is: any time domain Resource of the physical downlink Control channel PDCCH associated with the first indication information, or any time domain Resource of a Control Resource Set (CORESET) associated with the first indication information.
In the second mode, the first indication information indirectly indicates the ending time domain resource of the first COT by indicating the remaining time information. In this way, the terminal may determine the location of the ending time domain resource in combination with the second reference time and the remaining time information.
The remaining time information may be used to indicate a remaining COT length of the first COT with respect to a second reference time. In a specific implementation, the specific representation of the remaining time information may be related to a time unit of the time domain resource.
Alternatively, in the case that the time unit of the time domain resource is a symbol, the remaining time information may be expressed as the number of symbols of the remaining COT.
For example, assuming that the symbols 1 to 8 are consecutive, the second reference time is symbol 1, and the remaining time information indicates that the number of symbols of the remaining COT is 7, the end time domain position is symbol 8.
In addition, in a specific implementation, the second reference time may be, but is not limited to, a starting time domain resource or an ending time domain resource of a PDCCH or a CORESET associated with the first indication information.
Mode three, the first indication information indicates: identification information of the ending time domain resource.
In a third mode, the first indication information directly indicates the ending time domain resource of the first COT through identification information indicating the ending time domain resource. In this way, the terminal may directly determine the position indicated with the identification information of the ending time domain resource as the position of the ending time domain resource.
In a specific implementation, optionally, the first indication information may indicate the identification information of the ending time domain resource through a bitmap.
A manner in which the first indication information indicates the identifier information of the ending time domain resource through a bitmap is similar to a manner in which the first indication information indicates the transmission state of the time domain resource of the first COT through a bitmap, which may specifically refer to the foregoing description and is not repeated here.
It should be noted that, at the same time, the first indication information indicates: in an implementation manner, a terminal may respectively indicate the transmission state of the time domain resource of the first COT and the end time domain resource of the first COT through different bitmaps under the condition of the transmission state of the time domain resource of the first COT and the end time domain resource of the first COT.
In another implementation, the terminal may respectively indicate the transmission state of the time domain resource of the first COT and the end time domain resource of the first COT through the same bitmap.
Corresponding to the foregoing first manner, optionally, each bit group of the bitmap may include three bits, where the first two bits of each bit group are used to indicate the transmission state of the time domain resource of the first COT, and the last bit is used to indicate whether the time domain resource is an end time domain resource.
Exemplarily, if a third bit of the bit group takes a value of 0, it indicates that the time domain resource corresponding to the bit group is not the ending time domain resource; and if the third bit of the bit group takes a value of 1, indicating that the time domain resource corresponding to the bit group is the ending time domain resource.
Corresponding to the foregoing second manner, optionally, a first transmission state of the time-domain resource group may be set in the association relationship, and in the first transmission state of the time-domain resource group, a certain time-domain resource is indicated as an end time-domain resource. Such as: and recording the identification information of the ending time domain resource as E, and under the condition that one time domain resource group comprises 14 symbols, if the transmission state of the time domain resource group is DDDDFFFFUUUE, indicating that the last symbol is the ending time domain resource.
Mode four, the first indication information indicates: identification information of time domain resources other than the first COT.
In a fourth mode, the first indication information indirectly indicates the ending time domain resource of the first COT through identification information indicating a time domain resource other than the first COT. In this way, the terminal may determine a previous time domain resource of the first time domain resource identified with the identification information as a position to end the time domain resource.
In a specific implementation, optionally, the first indication information may indicate, by using a bitmap, identification information of a time domain resource other than the first COT.
A manner in which the first indication information indicates the identifier information of the ending time domain resource through a bitmap is similar to a manner in which the first indication information indicates the transmission state of the time domain resource of the first COT through a bitmap, which may specifically refer to the foregoing description and is not repeated here.
In practical applications, the bitmap for indicating the time domain resources other than the first COT and the bitmap for indicating other information of the first COT may be the same bitmap or different bitmaps.
Corresponding to the foregoing first manner, in a scenario where the same bitmap is used to indicate the transmission state of the time domain resource of the first COT and the identification information of the time domain resource other than the first COT, optionally, each bit group of the bitmap may include three bits, where the first two bits of each bit group are used to indicate the transmission state of the time domain resource of the first COT, and the last bit is used to indicate whether the time domain resource is the time domain resource other than the first COT.
Exemplarily, if a third bit of the bit group takes a value of 0, it indicates that the time domain resource corresponding to the bit group is not a time domain resource other than the first COT; and if the value of the third bit of the bit group is 1, indicating that the time domain resource corresponding to the bit group is a time domain resource other than the first COT.
Corresponding to the foregoing second manner, optionally, a second transmission state of the time-domain resource group may be set in the association relationship, and in the second transmission state of the time-domain resource group, the time-domain resources in the time-domain resource group may be indicated as time-domain resources other than the first COT. Such as: note that the identification information of the time domain resources other than the first COT is O, and if one time domain resource group includes 14 symbols, if the transmission state of the time domain resource group is ddddffffeooo, it indicates that the 11 th symbol in the time domain resource group is an end time domain resource of the first COT, and the 12 th symbol and the 14 th symbol are time domain resources other than the first COT.
It should be understood that, in practical applications, the network side may indicate the ending time domain resource of the first COT in combination with at least two of the above manners one to four, so as to improve accuracy of the indication of the ending time domain resource of the first COT.
And thirdly, identification information of the first COT.
In this embodiment, the identification information of the first COT may be used to determine the COT indicated by the first indication information, so as to facilitate a terminal to distinguish whether the COTs indicated by different indication information are the same COT.
In an implementation manner, the first indication information may directly carry identification information of the first COT to identify the COT indicated by the first indication information.
In another implementation manner, optionally, when the first indication information indicates the identification information of the first COT, the first indication information is specifically used to indicate:
whether the first COT and the second COT are the same COT or not;
the second COT corresponds to second indication information, where the second indication information is the last indication information corresponding to the COT that is received before the terminal receives the first indication information.
Specifically, if the first COT and the second COT are the same COT, it indicates that the first indication information and the second indication information are used for indicating related information of the same COT, and since the first indication information is subsequent to the second indication information, the terminal may update the related information of the COT based on the first indication information, so that the flexibility of determining the related information of the COT may be improved.
Step 202, according to the first indication information, executing an operation on the first COT.
During specific implementation, the terminal executes an operation on the first COT according to the relevant information of the first COT indicated by the first indication information. Therefore, it can be understood that the operation performed by the terminal on the first COT is related to the specific structure of the first COT, and is specifically described as follows.
Optionally, the first indication information indicates that the transmission state of the first time domain resource of the first COT is: uplink transmission or target downlink transmission;
the executing, at the first COT, an operation according to the first indication information includes:
stopping performing a clear channel detection, CCA, on the first time domain resources.
The first time domain resource may be any time domain resource in the first COT.
In practical application, when the first indication information indicates that the transmission status of the first time domain resource is uplink transmission, the terminal may default that there is uplink transmission in the first time domain resource, and therefore, may stop performing downlink transmission and/or CCA in the first time domain resource.
When the first indication information indicates that the transmission status of the first time domain resource is the target downlink transmission, the terminal may default that there is downlink transmission in the first time domain resource, and thus may stop performing uplink transmission and/or CCA in the first time domain resource.
In this way, by stopping performing the clear channel detection CCA on the first time domain resource, the power consumption of the terminal may be reduced.
Optionally, the first indication information indicates that the transmission state of the second time domain resource of the first COT is: a first downlink transmission;
the executing, at the first COT, an operation according to the first indication information includes:
and under the condition that the second time domain resource is configured with a search space, performing Physical Downlink Control Channel (PDCCH) monitoring on the second time domain resource.
The second time domain resource may be any time domain resource in the first COT.
Optionally, the first indication information indicates that a transmission state of a third time domain resource of the first COT is: second downlink transmission;
the executing, at the first COT, an operation according to the first indication information includes:
stopping performing PDCCH monitoring on the third time domain resource.
The third time domain resource may be any time domain resource in the first COT.
In this case, even if a Radio Resource Control (RRC) allocates a search space in the third time domain Resource, the terminal does not perform PDCCH monitoring in the third time domain Resource.
In this way, by stopping performing PDCCH monitoring on the third time domain resource, terminal power consumption may be reduced.
Optionally, the first indication information indicates that a transmission state of a fourth time domain resource of the first COT is: flexible transmission;
the executing, at the first COT, an operation according to the first indication information includes:
detecting whether the fourth time domain resource meets a first preset condition;
if the fourth time domain resource meets the first preset condition, stopping executing at least one of the following items on the fourth time domain resource: downlink and uplink transmissions, CCA;
wherein the first preset condition is as follows: the fourth time domain resource is located between a fifth time domain resource and a sixth time domain resource of the first COT; the transmission states of the time domain resources between the fifth time domain resource and the sixth time domain resource are flexible transmission; and the transmission states of the fifth time domain resource and the sixth time domain resource are target downlink transmission and uplink transmission respectively.
As can be seen from the foregoing, the specific function of the time domain resource whose transmission status is flexible transmission also needs to be determined by combining the position of the time domain resource within the first COT. Therefore, for the fourth time domain resource, the terminal needs to further detect whether the fourth time domain resource meets the first preset condition.
Specifically, if the first preset condition is met, the fourth time domain resource may be regarded as a converted time domain resource, so that transmission and/or CCA may not be performed on the fourth time domain resource any more, and power consumption of the terminal may be reduced.
If the first preset condition is not met, the fourth time domain resource can be regarded as the time domain resource to be scheduled. As can be seen from the foregoing, for the time domain resource to be scheduled, the transmission state may be switched to target downlink transmission or uplink transmission. Therefore, optionally, after detecting whether the fourth time domain resource satisfies the first preset bar, the method further includes:
if the fourth time domain resource does not meet the first preset condition, executing any one of the following items:
under the condition of receiving third indication information, executing operation on the fourth time domain resource according to the transmission state of the fourth time domain resource indicated by the third indication information;
and under the condition that the third indication information is not received, executing operation on the fourth time domain resource according to the transmission state of the fourth time domain resource before the terminal receives the first indication information.
The third indication information may be understood as scheduling indication information of a transmission state of the fourth time domain resource, and the transmission state of the fourth time domain resource may be scheduled as uplink transmission or target downlink transmission.
If the terminal receives the third indication information and the third indication information schedules the transmission state of the fourth time domain resource as uplink transmission, the terminal needs to perform uplink transmission on the fourth time domain resource and does not perform downlink transmission and/or CCA on the fourth time domain resource.
If the terminal receives the third indication information and the third indication information schedules the transmission state of the fourth time domain resource as target downlink transmission, the terminal needs to perform downlink transmission on the fourth time domain resource and does not perform uplink transmission and/or CCA on the fourth time domain resource.
If the terminal does not receive the third indication information, the terminal may default the transmission state of the fourth time domain resource to the transmission state of the fourth time domain resource before the terminal receives the first indication information.
Such as: assuming that the transmission state of the fourth time domain resource is uplink transmission before the terminal receives the first indication information, the transmission state of the fourth time domain resource may be switched to uplink transmission.
Assuming that the transmission state of the fourth time domain resource is the target downlink transmission before the terminal receives the first indication information, the transmission state of the fourth time domain resource may be switched to the target downlink transmission.
Optionally, when the first indication information indicates that there is an end time domain resource of the first COT, the performing, according to the first indication information, an operation at the first COT includes at least one of:
if a seventh time domain resource which does not indicate a transmission state exists in the first COT, configuring the transmission state of the seventh time domain resource to flexible transmission;
ignoring an indication of time domain resources other than the first COT by the first indication information;
and configuring the transmission state of the ending time domain resource to be the same as the transmission state of an eighth time domain resource, wherein the eighth time domain resource is the last time domain resource of the ending time domain resource.
For ease of understanding, examples are illustrated below:
it is assumed that the first COT includes symbol 1 through symbol 10, and symbol 10 is an end time domain resource of the first COT.
If the first indication information does not indicate the transmission states of the symbols 2 to 8, the terminal may configure the transmission states of the symbols 2 to 9 to be flexible states.
If the first indication information indicates that there is a transmission state of symbols 11 to 14, since the symbols 11 to 14 do not belong to the first COT, the terminal may ignore the indication of the transmission state of symbols 11 to 14 by the first indication information.
If the first indication information indicates that the transmission status of the symbol 9 is uplink transmission, the symbol 9 is the last time domain resource of the symbol 10, and therefore, the transmission status of the symbol 10 can be configured as uplink transmission.
Optionally, before the first COT performs an operation according to the first indication information, the method further includes:
receiving configuration information, the configuration information configuring: the terminal performs a first type of Listen Before Talk (LBT) in a ninth time domain resource of the first COT, and performs uplink transmission in the ninth time domain resource after the first type of LBT is successful;
the executing, at the first COT, an operation according to the first indication information includes:
under the condition that the ninth time domain resource meets a second preset condition, performing a second type of LBT on the ninth time domain resource, and after the second type of LBT succeeds, performing uplink transmission on the ninth time domain resource;
wherein the ninth time domain resource satisfying the second preset condition includes any one of:
the transmission state of the ninth time domain resource is uplink transmission;
the transmission state of the ninth time domain resource is flexible transmission, and the ninth time domain resource does not satisfy a third preset condition, where the third preset condition is that the ninth time domain resource is located between a fifth time domain resource and a sixth time domain resource of the first COT; the transmission states of the time domain resources between the fifth time domain resource and the sixth time domain resource are flexible transmission; and the transmission states of the fifth time domain resource and the sixth time domain resource are target downlink transmission and uplink transmission respectively.
In this embodiment, after receiving the configuration information, if the time domain resource configured by the configuration information satisfies the second preset condition, the terminal may change the type of LBT, not perform LBT according to the LBT type configured by the configuration information, and perform shared COT transmission on the ninth time domain resource.
Further, the listening duration of the second type of LBT is shorter than the listening duration of the first type of LBT. Alternatively, the first type of LBT may be that of Cat4, and the second type of LBT may be that of Cat 2.
In addition, in this embodiment, if the ninth time domain resource does not satisfy the second preset condition, the terminal may not perform LBT on the ninth time domain resource and perform uplink transmission, so as to reduce power consumption.
It should be noted that, in this embodiment, when the first indication information indicates that the transmission state of a certain time domain resource is the target downlink transmission, the transmission state of the time domain resource may specifically be the first downlink transmission or the second downlink transmission.
According to the COT indicating method, the terminal can acquire the relevant information of the COT and execute the operation according to the acquired relevant information of the COT, so that part of unnecessary operation can be reduced, and power consumption is further reduced.
It should be noted that, various optional implementations described in the embodiments of the present invention may be implemented in combination with each other or implemented separately, and the embodiments of the present invention are not limited thereto.
The invention provides a method for indicating a channel occupation time structure based on different symbol states defined in a time slot.
One, a combination that may include one or more of the following:
1) indicating a downlink transmission state D: indicating the symbol of the terminal to be downlink transmission, and monitoring downlink signals/channels, such as PDCCH monitoring, reference signal monitoring, etc., is required;
wherein, the symbol which has downlink signal transmission and contains PDCCH transmission is further indicated as P state; otherwise, the state is indicated as D state.
2) And indicating an uplink transmission state U: indicating the terminal that the symbol is uplink transmission, and transmitting an uplink signal/channel, such as PUSCH transmission, SRS transmission, PUCCH transmission, PRACH transmission, and the like;
3) indicate flexible transmission state F:
when the F state symbol is between the D state symbol and the U state symbol in the same COT, indicating the terminal not to perform any transceiving processing;
otherwise, the F state symbol indicates that the symbol is not scheduled, the terminal does not change, and the receiving and sending processing is carried out according to the original configuration.
4) Indicating the COT end time:
option 1, indicating the specific position of the ending symbol, namely slot offset and symbolndex relative to the current slot;
option 2, indicating the length of the remaining COT, for example, the number of symbols of the remaining COT, and referring to the starting or ending symbol of the PDCCH or CORESET associated with the detected DCI at the time point;
option 3, COT end symbol is indicated as COT end state E;
and in Option 4, the COT outer symbol is indicated as Out of COT state O, and a symbol before the first O state symbol is a COT end symbol.
5) Identification information indicating COT:
option 1, using 1bit toggle bit to indicate whether the last SFI indicates the COT which is newly obtained or not;
option 2-introduction of COT Identification (ID) indication.
And II, based on the user behavior indicated by the COT.
1) When the symbol is indicated as a downlink (D) state, the user assumes that there must be downlink transmission in the symbol, does not perform any uplink signal (including SRS, PUCCH, PUSCH, PRACH, etc.) transmission, and/or does not perform CCA.
Optionally, when there is a P-state indication, the user performs PDCCH monitoring on the P-state symbol if the RRC configures the search space, and does not perform PDCCH monitoring on the D-state symbol (even if the RRC configures the search space).
2) When the symbol is indicated as a downlink (U) state, the user assumes that there must be uplink transmission in the symbol, does not perform downlink signal reception or measurement (PDCCH, PDSCH, SSB, CSI-RS, etc.), and/or does not perform CCA;
3) when the symbol is indicated as a flexible (F) state, if the F symbol is between the indicated D (or P) symbol and U symbol, the user assumes that the symbol is a converted symbol and does not perform any uplink signal transmission nor any downlink signal reception or measurement; otherwise, the user assumes that the symbol is a symbol to be scheduled, and needs to continue monitoring a subsequent COT indication to update the state of the symbol, and the symbol can perform downlink signal transmission or uplink signal transmission.
4) When the symbol is determined or indicated as a COT ending symbol, the indication state of the symbol in the COT is an effective state, and the non-indicated symbol is a flexible state; an indication outside the COT is an invalid indication. When the symbol indicates the E state, the symbol configuration state is the same as a symbol.
5) For symbols determined to be scheduled in one SFI (F state symbols not between D and U), the user continues to monitor the COT information, and subsequent SFIs may override the symbol state with other states. For the COT ending symbol determined as the F state, the COT ending symbol can be changed and adjusted in the subsequent SFI.
7) For a UE transmitting a configuration grant (configured grant) PUSCH, PUCCH, or SRS, a shared COT transmission may be performed on an F symbol or U symbol determined to be non-scheduled according to COT information, that is, LBT of Cat2 is adopted.
Example one
Assuming that the base station performs full downlink transmission in the COT after acquiring the channel, the SFI indication example is shown in fig. 3 a.
In fig. 3a, 3 SFIs are included, and the subsequent indication of SFI may override the F symbol of the previous indication of SFI. The second SFI received as in fig. 3a indicates some of the F symbols indicated by the first SFI as D symbols, and the third SFI received as in fig. 3a may indicate all of the F symbols indicated in the second SFI as D symbols.
The user stops any uplink transmission on the symbol indicated as D.
In a specific implementation, the SFI may be transmitted via a multicast GC-PDCCH. In fig. 3a, black padding indicates reception of the SFI.
Example two
Assuming that the base station schedules uplink transmission in the COT after acquiring the channel, the SFI indication is shown in fig. 3 b.
The F symbol is located between the D symbol and the U symbol in fig. 3b, and thus, the F symbol in fig. 3b may be regarded as a conversion symbol, and the terminal does not perform any transmission and reception in the F symbol of fig. 3 b. In fig. 3b, black padding indicates reception of the SFI.
The invention can indicate the COT information state, and the terminal can save power according to the COT information state.
Referring to fig. 4, fig. 4 is a second flowchart of a method for indicating COT according to an embodiment of the present invention. The COT indicating method is applied to network side equipment.

Optionally, the first indication information indicates, through a bitmap, identification information of the ending time domain resource.

whether the first COT and the second COT are the same COT or not;
the second COT corresponds to second indication information, where the second indication information is the last indication information corresponding to the COT that is sent before the network side device sends the first indication information.
In the method for indicating the COT according to the embodiment, the network side device sends the indication information for indicating the relevant information of the COT to the terminal, so that the terminal can acquire the relevant information of the COT and execute an operation according to the acquired relevant information of the COT, thereby reducing part of unnecessary operations and further reducing power consumption.
It should be noted that, the present embodiment is implemented as a network side device corresponding to the foregoing method embodiment, and therefore, reference may be made to the relevant description in the foregoing method embodiment, and the same beneficial effects may be achieved. To avoid repetition of the description, the description is omitted.
