Description

Resource allocation method and device
Technical Field
The embodiment of the application relates to the technical field of communication, in particular to a resource allocation method and device.
Background
Currently, the frequency spectrum used by wireless communication systems can be divided into two broad categories: licensed spectrum (licensed spectrum) and unlicensed spectrum (unlicensed spectrum). With the development of communication technology, the amount of information transmitted in a communication network is increasing day by day, and the occupation of unlicensed spectrum (unlicensed spectrum) transmission information can improve the data throughput in the communication network and better meet the requirements of users.
In order to better use the unlicensed spectrum, corresponding regulations are promulgated by countries or regions to ensure the fairness and the normative of the use of the spectrum. For example, Listen Before Talk (LBT) mechanisms may be employed to preempt unlicensed spectrum. The LBT mechanism requires that a device using the spectrum must listen to the corresponding spectrum first, and for example, when the base station occupies the unlicensed spectrum, the base station may detect the received energy of the unlicensed spectrum to see whether the spectrum is occupied. If the spectrum is not busy, i.e., unoccupied, the base station may occupy the spectrum and begin data transmission. In this spectrum, the base station can only occupy a certain time, which may be referred to as a Channel Occupancy Time (COT) of the unlicensed spectrum.
Since the time of the unlicensed spectrum occupied by the access network device is random, the time for transmitting downlink data in the uplink and downlink frame structure configuration information of the COT is the same as the time for transmitting uplink data in a configuration Grant (GF) parameter pre-configured to the terminal by the base station, so that a situation that a transmission manner at the same time point conflicts exists, and the terminal cannot transmit uplink data on the licensed spectrum. For example, as shown in fig. 1, in a GF parameter configured by an access network device to a terminal, a transmission period is 1 slot (slot), where 1 slot includes 14 symbols, uplink data is transmitted on the 6 th symbol of each slot, an uplink and downlink frame structure of a COT is configured, and the access network device occupies an unlicensed spectrum at a time point corresponding to the 6 th symbol and starts to transmit downlink data, for example: the 1 st symbol (corresponding to the 6 th symbol of the licensed spectrum) in the uplink and downlink frame structure configuration of the COT is a downlink (D) symbol, and conflicts with the time for transmitting uplink data, which is configured to the terminal by the access network device, so that the terminal cannot transmit uplink data on the 6 th symbol.

The embodiment of the present application does not limit the type of the communication apparatus 300. In the embodiment of the present application, the chip system may be composed of a chip, and may also include a chip and other discrete devices.
The resource allocation method provided in the embodiment of the present application is described below with reference to the system shown in fig. 2. Each of the communication devices mentioned in the following method embodiments may have a component shown in fig. 3, and is not described again. In addition, in the following embodiments of the present application, names of messages interacted among devices or names of parameters in the messages are only an example, and other names may also be used in a specific implementation.
Fig. 4 provides a resource allocation method for the embodiment of the present application, and as shown in fig. 4, the method may include:
step 401: the access network equipment configures at least two sets of configuration authorization parameters of the terminal.
The access network device may be the access network device in the system shown in fig. 2. The terminal may be any of the terminals in the system shown in fig. 2.
The configuration grant parameter may be referred to as a (CG) parameter or a Grant Free (GF) parameter, and may be used to indicate a time unit for transmitting uplink data. In this embodiment of the application, the time unit for sending uplink data, which is indicated by the configuration authorization parameter, may be one time unit, or may also be two or two time units. The time unit may be a symbol (symbol) or a slot (slot) or a subframe (subframe) on a licensed spectrum, such as: the time unit may be 1 symbol or a plurality of symbols, etc.; alternatively, the time unit may be a time indicated by any combination of symbols, slots, subframes, etc. on the licensed spectrum, such as: the time unit may be 1 slot, 2 symbols, etc., without limitation.
In the embodiments of the present application, the time units indicated by different configuration authorization parameters are different. Each configuration authorization parameter corresponds to an Identifier (ID) of the configuration authorization parameter, and the ID of the configuration authorization parameter is used for identifying the configuration authorization parameter. For example, the ID of the configuration authorization parameter may be configured by the access network device, and the identity of different configuration authorization parameters may be different. Such as: the identifier of the configuration authorization parameter may be an index (index) of the configuration authorization parameter, and may also be any combination of letters, chinese characters, numbers, special characters, and the like, which are easy for a user to recognize, understand, and remember, and other identifiers, without limitation. For example, the access network device configures four configuration authorization parameters of the terminal: GF parameter 1, GF parameter 2, GF parameter 3, and GF parameter 4, wherein the identification of GF parameter 1 may be GF ID1, the identification of GF parameter 2 may be GF ID2, the identification of GF parameter 3 may be GF ID3, the identification of GF parameter 4 may be GF ID4, and the like.
For example, the configuration grant parameter may include, but is not limited to, an offset between a start symbol of a time unit for transmitting uplink data for the first time and a reference time point, a length of the time unit for transmitting uplink data, a start symbol of each time unit for transmitting uplink data, and one or more information in a transmission period, and may further include other information, such as: redundancy version (redundancy version), and the like. The transmission period may be a time interval between two adjacent time units for transmitting uplink data, and the reference time point may be a predetermined time point, such as: may be subframe 0. For example, if the configuration authorization parameter 1 includes: the offset is 4 slots, the transmission period is 1 slot, the starting symbol is the 3 rd symbol, and the length of the time unit for transmitting the uplink data is 2 symbols, then the configuration authorization parameter 1 may be used to instruct the terminal to start at the 4 th slot after the subframe 0, and transmit the uplink data on the 3 rd and 4 th symbols in the 4 th slot.
In the embodiment of the present application, the access network device may configure at least two sets of configuration authorization parameters for the terminal according to information such as uplink and downlink traffic volumes interacted between the terminal and the access network device, and channel conditions between the terminal and the access network device, and send the configured at least two sets of configuration authorization parameters to the terminal, for example:
in an example, a terminal may send a Radio Resource Control (RRC) establishment request to an access network device, the access network device receives the RRC establishment request, carries at least two sets of configuration authorization parameters in an RRC message according to the RRC establishment request, and sends the RRC message to the terminal; wherein the RRC establishment request is for requesting establishment of an RRC connection with the access network device. In this way, the access network device can configure the configuration authorization parameter to the terminal in the RRC establishment procedure.
In another example, the access network device may further configure authorization parameters for the terminal in a manner of combining an RRC message and Downlink Control Information (DCI), such as: the access network equipment can firstly carry a plurality of sets of configuration authorization parameters in an RRC message and send the RRC message to the terminal, subsequently, the access network equipment sends an activation instruction to the terminal through DCI to indicate that at least two sets of configuration authorization parameters in the configuration authorization parameters included in the RRC message are activated, and after receiving the activation instruction, the terminal obtains at least two sets of configuration authorization parameters from the configuration authorization parameters included in the RRC message according to the activation instruction.
It should be noted that, when the access network device configures at least two sets of configuration authorization parameters for the terminal, the identifier of the configuration authorization parameters and the configuration authorization parameters may also be configured to the terminal correspondingly, for example: and correspondingly carrying the configuration authorization parameters and the identifiers of the configuration authorization parameters in an RRC message and sending the RRC message to the terminal.
Step 402: the access network equipment determines the COT and the configuration information of the uplink and downlink frame structures of the COT.
The access network device may determine the COT by using the prior art, for example: the COT can be determined using LBT techniques.
The uplink and downlink frame structure configuration information of the COT may be used to indicate a time unit for transmitting uplink data, a time unit for transmitting downlink data, and a flexibly configured time unit during the COT. Wherein the flexibly configured time units are defined as follows: if a certain time unit is used for sending uplink data or for sending downlink data, the time unit may be called a flexibly configured time unit. The COT period may include one or more transmission periods, one transmission period may be 1 timeslot, 1 subframe, or 1 frame, and uplink and downlink configurations in each transmission period in the COT may be the same or different.
In the embodiment of the application, the communication protocol (such as the third generation partnership project (the 3) can be usedrdgenerationnpartnershirp project, 3GPP) TS38.214), where each piece of uplink and downlink frame configuration information corresponds to one identifier, and the identifiers corresponding to different pieces of uplink and downlink configuration information are different. After the access network device determines the COT, the access network device may configure information from one or more pre-configured uplink and downlink frame structures according to information such as current uplink and downlink traffic volume, channel conditions, and the likeSelecting a kind of uplink and downlink frame structure configuration information as the uplink and downlink frame structure configuration information of the COT, and using the identifier of the selected uplink and downlink frame structure configuration information as the identifier of the COT.
For example, as shown in fig. 5a, taking a time unit as an example, the following uplink and downlink frame configuration information 1 may be configured in advance in the communication protocol: DDDDDFUUUUUUUU, configuration information of uplink and downlink frame structure 2: DDFUUUUUUUUUUU, if the COT determined by the access network device includes two transmission periods, one transmission period is 1 time slot, and 1 time slot includes 14 symbols, the access network device may adopt the following configurations in both the first transmission period and the second transmission period of the COT: DDDDDFUUUUUUUU; as shown in fig. 5a, the following configuration may be adopted in the first transmission period of the COT: and the DDDDDFUUUUUUUUU adopts the following configuration in the second transmission period: DDFUUUUUUUUUUU, without limitation.
In the embodiments of the present application, the symbol "D" represents a time unit for transmitting downlink data, the symbol "U" represents a time unit for transmitting uplink data, and the symbol "F" represents a flexibly configured time unit.
Step 403: the access network equipment selects a first configuration authorization parameter from at least two sets of configuration authorization parameters according to the uplink and downlink frame structure configuration information of the COT and at least two sets of configuration authorization parameters of the terminal configured by the access network equipment.
The time unit indicated by the first configuration authorization parameter is different from the time unit used for sending downlink data in the COT period; alternatively, it may be described that the time unit corresponding to the time unit indicated by the first configuration authorization parameter during the COT is a time unit for transmitting uplink data or a flexibly configured time unit.
For example, after determining the uplink and downlink frame structure configuration information of the COT, the access network device compares the time unit indicated by each configuration authorization parameter with the transmission mode of the time unit in the COT period, determines the transmission mode of the time unit corresponding to the time unit indicated by the configuration authorization parameter in the COT period, and if the time unit in the COT period is not used for transmitting downlink data, determines the configuration authorization parameter as the first configuration authorization parameter, otherwise, determines that the terminal cannot transmit uplink data in the time unit indicated by the configuration authorization parameter.
For example, as shown in fig. 5b, the access network device configures three configuration authorization parameters to the terminal: GF parameters 1, 2 and 3, the transmission period of each GF parameter being 1 slot, each slot comprising 14 symbols: symbol 0-symbol 13, the COT occupied by the access network device includes multiple transmission periods, each transmission period is 1 slot, and each slot includes 14 symbols: symbol 0 to symbol 13. As shown in fig. 5b, the time unit for transmitting uplink data indicated by GF parameter 1 is: symbol 6, the time unit for transmitting uplink data indicated by GF parameter 2 is: symbol 9, the time unit for transmitting uplink data indicated by GF parameter 3 is: symbol 12, where symbol 6 indicated by GF parameter 1 corresponds to symbol 0 during the COT, and as can be seen from fig. 5b, symbol 0 during the COT is used for transmitting downlink data, and the time cell indicated by GF parameter 1 corresponds to the time cell during the COT for transmitting downlink data, both transmission schemes collide, so that the terminal cannot transmit uplink data in the time cell indicated by GF parameter 1; similarly, symbol 6 indicated by GF parameter 1 corresponds to symbol 3 in the COT period, symbol 3 in the COT period is also used for transmitting downlink data, and the terminal cannot transmit uplink data in the time unit indicated by GF parameter 2. The symbol 12 indicated by the GF parameter 3 corresponds to the symbol 6 in the COT period, the symbol 6 in the COT period is used for transmitting downlink data, the time cell indicated by the GF parameter 3 corresponds to the time cell for transmitting uplink data in the COT period, the transmission manners of the two are consistent, and the terminal can transmit uplink data in the time cell indicated by the GF parameter 3. At this time, the access network device may use the GF parameter 3 as the first configuration authorization parameter.
It should be noted that the first configuration authorization parameter selected by the access network device from the at least two sets of configuration authorization parameters may include one set of configuration authorization parameter, and may also include multiple sets of configuration authorization parameters. When the access network device selects a plurality of sets of configuration authorization parameters from at least two sets of configuration authorization parameters, the access network device may use the configuration authorization parameter with the smallest index number of the plurality of sets of configuration authorization parameters as the finally selected configuration authorization parameter, or use the configuration authorization parameter with the largest index number of the plurality of sets of configuration authorization parameters as the finally selected configuration authorization parameter, or use the configuration authorization parameter corresponding to the time unit which is first used for sending uplink data in the plurality of sets of configuration authorization parameters as the finally selected configuration authorization parameter.
For example, the access network device selects two sets of configuration authorization parameters from at least two sets of configuration authorization parameters: GF parameters 3 and 4, where the index number of the GF parameter 3 is 3, the index number of the GF parameter 4 is 4, the time unit indicated by the GF parameter 3 is symbol 3, and the time unit indicated by the GF parameter 4 is symbol 6, the access network device may use the GF parameter 3 as the finally selected configuration authorization parameter, or use the GF parameter 4 as the finally selected configuration authorization parameter, or use the GF parameter 3 indicating symbol 3 as the finally selected configuration authorization parameter, without limitation.
Step 404: the access network equipment transmits DCI to the terminal during the COT; the DCI comprises indication information, wherein the indication information is used for indicating the terminal to transmit uplink data on the time unit indicated by the first configuration authorization parameter.
In embodiments of the present application, the sending, by an access network device, DCI to a terminal during a COT may include: the access network equipment transmits the DCI in the time unit which is firstly used for transmitting the downlink data during the COT.
In one example, the indication information may be an identification of the first configuration authorization parameter.
Such as: the indication information may be an index number of the first configuration authorization parameter, and the like.
In another example, the indication information may be an identifier of the COT, where the identifier of the COT may be used to identify uplink and downlink configuration information of the COT, and a corresponding relationship exists between the uplink and downlink configuration information of the COT and the first configuration authorization parameter.
The identifier of the COT may also be described as an identifier of uplink and downlink configuration information. It can be understood that, when the COT period includes multiple transmission periods, and uplink and downlink frame structure configuration information of different transmission periods are different, for different transmission periods, identifiers of COTs indicated to the terminal by the access network device are different, so that the terminal finds, according to the received identifier of the COT, a configuration authorization parameter corresponding to the uplink and downlink frame structure configuration information identified by the COT identifier, and sends data in a time unit indicated by the configuration authorization parameter.
Step 405: and the terminal receives DCI sent by the access network equipment in the COT period, and sends uplink data on the time unit indicated by the first configuration authorization parameter according to the indication information in the DCI.
When the indication information includes the identifier of the first configuration authorization parameter, the terminal may obtain, according to the identifier of the first configuration authorization parameter, the first configuration authorization parameter identified by the identifier of the first configuration authorization parameter from at least two sets of configuration authorization parameters, and send the uplink data in the time unit indicated by the first configuration authorization parameter.
When the indication information includes the identifier of the COT, the terminal may first determine, according to the identifier of the COT, uplink and downlink configuration information of the COT identified by the identifier of the COT, then determine, according to a corresponding relationship between the uplink and downlink configuration information and the configuration authorization parameter, a first configuration authorization parameter corresponding to the uplink and downlink configuration information of the COT, and send uplink data on a time unit indicated by the first configuration authorization parameter.
The corresponding relation between the uplink and downlink configuration information and the configuration authorization parameters can also be specified in the communication protocol in advance. When the indication information includes the identifier of the COT, the terminal may obtain, from the communication protocol, a correspondence between the uplink and downlink configuration information and the configuration authorization parameter and an identifier corresponding to the uplink frame configuration information, determine the first configuration authorization parameter according to the identifier of the COT indicated by the access network device and the obtained information, and send the uplink data on the time unit indicated by the first configuration authorization parameter.
For example, as shown in fig. 5c, the uplink and downlink configuration information 1 corresponds to the GF parameter 1, and the uplink and downlink configuration information 2 corresponds to the GF parameter 2, and when the uplink and downlink configuration information of the COT is the uplink and downlink configuration information 1 and the indication information received by the terminal includes the identifier of the uplink and downlink configuration information 1, the terminal may select to transmit the uplink data in the time unit indicated by the GF parameter 1 according to the correspondence shown in fig. 5 c.
It should be noted that, in this embodiment of the present application, one piece of uplink and downlink configuration information in the correspondence between the uplink and downlink configuration information and the configuration authorization parameters may correspond to multiple sets of configuration authorization parameters, and when the terminal determines multiple sets of configuration authorization parameters corresponding to the uplink and downlink configuration information of the COT according to the identifier of the COT, the terminal may select, from the multiple sets of configuration authorization parameters, the configuration authorization parameter with the smallest index number as the first configuration authorization parameter, or select, from the multiple sets of configuration authorization parameters, the configuration authorization parameter with the largest index number as the first configuration authorization parameter, or select, from the multiple sets of configuration authorization parameters, the configuration authorization parameter corresponding to the time unit that is first used for sending uplink data as the first configuration authorization parameter, which is not limited.
Further, after step 405, the method may further include: the access network equipment can receive uplink data on the time unit indicated by the first configuration authorization parameter.
It should be noted that, in the method shown in fig. 4, it is not limited to send the indication information to the terminal through DCI, a signaling may be added, and the indication information may be included in the added signaling and sent to the terminal, which is not limited.
Based on the method shown in fig. 4, the access network device may select a first configuration authorization parameter from multiple sets of configuration authorization parameters, where a time unit indicated by the first configuration authorization parameter is different from a time unit used for sending downlink data during a COT, and the access network device indicates the selected first configuration authorization parameter to the terminal, so that the terminal sends uplink data in the time unit indicated by the first configuration authorization parameter, so as to avoid a time point collision with the time point when the access network device sends the downlink data.
In another possible scheme, if a time unit indicated by the configuration authorization parameter configured to the terminal by the access network device conflicts with a transmission mode of a time unit during the COT, the access network device may further determine that the terminal transmits uplink data in a second time unit after the first time unit indicated by the configuration authorization parameter, where the second time unit is different from the time unit used for transmitting downlink data during the COT, so as to avoid the conflict with the time unit used for transmitting downlink data during the COT. Specifically, the implementation process is shown in fig. 6.
Fig. 6 is a further resource allocation method provided in the embodiment of the present application, and as shown in fig. 6, the method may include:
step 601: and the access network equipment configures the configuration authorization parameters of the terminal.
The access network device may be the access network device in the system shown in fig. 2. The terminal may be any of the terminals in the system shown in fig. 2.
In the embodiment of the present application, the authorization parameter configured to the terminal by the access network device may include one set of configuration authorization parameter, and may also include at least two sets of configuration authorization parameters. The process of configuring the authorization parameter for the access network device and the configuration authorization parameter for the terminal may refer to the process described in step 401, which is not described again.
Step 602: the access network equipment determines the COT and the configuration information of the uplink and downlink frame structures of the COT.
The relevant description of the uplink and downlink frame structure configuration information of the COT and the execution process of step 602 may refer to the description in step 402, and are not described again.
Step 603: and the access network equipment determines that the terminal sends the uplink data on a second time unit after the first time unit according to the uplink and downlink frame structure configuration information of the COT and the configuration authorization parameter configured to the terminal by the access network equipment.
The starting symbol of the second time unit is separated from the starting symbol of the first time unit by K symbols, wherein K is a positive integer. I.e. K is an integer greater than or equal to 1.
The first time unit is a time unit indicated by the first configuration authorization parameter, the first configuration authorization parameter is included in the configuration authorization parameter configured to the terminal by the access network device, and the first time unit is the same as a time unit used for sending downlink data during the COT. The second time unit after the first time unit is different from the time unit for sending the downlink data during the COT, such as: the time unit corresponding to the second time unit after the first time unit in the COT period is not used for sending downlink data, that is, the time unit corresponding to the second time unit in the COT period is: time units for transmitting uplink data or flexibly configured time units.
Exemplarily, if the access network device configures only one set of configuration authorization parameters for the terminal in step 601, the first configuration authorization parameter is the set of configuration authorization parameters; if, in step 601, the access network device configures at least two sets of configuration authorization parameters to the terminal, the first configuration authorization parameter is any one of the at least two sets of configuration authorization parameters, such as: the configuration authorization parameter with the largest index number in the at least two sets of configuration authorization parameters may be provided, the configuration authorization parameter with the smallest index number in the at least two sets of configuration authorization parameters may be provided, the configuration authorization parameter corresponding to the time unit which is first used for sending uplink data in the at least two sets of configuration authorization parameters may be provided, and the like, without limitation.
For example, as shown in fig. 7a, the access network device configures a terminal with a set of configuration authorization parameters: the transmission period of the GF parameter 1 is 1 slot, and 1 slot includes 14 symbols: symbol 0-symbol 13, the COT occupied by the access network device includes multiple transmission periods, each transmission period is 1 slot, and each slot includes 14 symbols: symbol 0 to symbol 13. As shown in fig. 7a, the time unit for transmitting uplink data indicated by GF parameter 1 is: symbol 6, and symbol 6 indicated by GF parameter 1 corresponds to symbol 0 during COT, symbol 0 during COT is used for transmitting downlink data, and the terminal cannot transmit uplink data in the time unit indicated by GF parameter 1, in view of this, the access network device determines a symbol which is not used for transmitting downlink data for the first time during COT: symbol 4 or symbol 5, determining that the terminal transmits the uplink data on the symbol corresponding to the symbol 4 or symbol 5, that is, the uplink data is transmitted on the 3 rd symbol (symbol 9) or the 4 th symbol (symbol 10) after the symbol 6 indicated by the GF parameter, so as to avoid time collision with the access network equipment for transmitting the downlink data.
As shown in fig. 7b, the access network device configures two sets of configuration authorization parameters to the terminal: GF parameter 1 and GF parameter 2, the transmission cycle of every set of GF parameter is 1 slot, and 1 slot includes 14 signs: symbol 0-symbol 13, the COT occupied by the access network device includes multiple transmission periods, each transmission period is 1 slot, and each slot includes 14 symbols: symbol 0 to symbol 13. As shown in fig. 7b, to avoid time collision with the access network device for transmitting downlink data, the access network device may select a GF parameter 2 from GF parameters 1 and 2, delay a symbol 6 indicated by the GF parameter 2 by 4 symbols, and transmit uplink data on a 4 th symbol after the symbol 6.
Step 604: the access network equipment transmits DCI to the terminal during the COT; the DCI comprises indication information, wherein the indication information is used for indicating the terminal to transmit uplink data on a second time unit after the first time unit.
In one example, if the access network device configures only one set of configuration authorization parameters for the terminal in step 601, the indication information may include K. In another example, if the access network device configures at least two sets of configuration authorization parameters to the terminal in step 601, the first configuration authorization parameter may include K and an identifier of the first configuration authorization parameter.
Step 605: and the terminal receives DCI sent by the access network equipment in the COT period, and sends uplink data in a second time unit after the first time unit indicated by the first configuration authorization parameter according to the indication information in the DCI.
When the indication information includes K, the terminal may directly send uplink data in a second time unit after the first time unit indicated by the first configuration authorization parameter according to K;
when the indication information includes K and the identifier of the first configuration authorization parameter, the terminal may determine the first configuration authorization parameter from the at least two sets of configuration authorization parameters according to the identifier of the first configuration authorization parameter, and then send uplink data in a second time unit after the first time unit indicated by the first configuration authorization parameter according to K.
Further, after step 605, the method may further include: and the access network equipment receives the uplink data on a second time unit after the first time unit indicated by the first configuration authorization parameter.
It should be noted that, in the method shown in fig. 6, it is not limited to send the indication information to the terminal through DCI, a signaling may be added, and the indication information may be included in the added signaling and sent to the terminal, which is not limited.
In addition, in the method shown in fig. 6, when the COT period includes multiple transmission periods, and the configuration in each transmission period is the same, the access network device only needs to determine one K value, and the terminal transmits uplink data in each transmission period according to the K value, after the time unit indicated by the configuration authorization parameter, on a time unit spaced by K symbols from the time unit indicated by the configuration authorization parameter. When the COT period includes multiple transmission periods and the configuration in each transmission period is different, different K values may exist for different transmission periods, at this time, the access network device may send the K corresponding to different transmission periods to the terminal, and the terminal sends uplink data according to different K values in different sending periods. For example, as shown in fig. 7c, the GF parameters configured by the access network device to the terminal are: the transmission period of the GF parameter 1 is 1 slot, and 1 slot includes 14 symbols: symbol 0-symbol 13, the COT occupied by the access network device includes two transmission periods, each transmission period is 1 slot, and each slot includes 14 symbols: symbol 0 to symbol 13. As shown in fig. 7c, to avoid time collision with the access network device for sending downlink data, in a first transmission period of the COT, a symbol for sending uplink data may be delayed by 6 symbols, and in a second transmission period of the COT, a symbol for sending uplink data may be delayed by 3 symbols, at this time, the access network device may indicate K to the terminal as 6 in the first period of the COT, and indicate K to the terminal as 3 in the second transmission period of the COT, so that the terminal sends uplink data on a symbol 12 (corresponding to the symbol 6 of the first slot in the COT) in the first slot, and sends uplink data on a symbol 9 (corresponding to the symbol 3 of the first slot in the COT) in the second slot.
Based on the method shown in fig. 6, the access network device may determine a second time unit after the first time unit and different from a time unit used for sending downlink data during the COT, and indicate the symbol number of an interval between the second time unit and the first time unit to the terminal, so that the terminal sends uplink data in the second time unit after the first time unit, and avoid a collision with a time point when the access network device sends downlink data.
The above-mentioned manner shown in fig. 4 or fig. 6 describes how the terminal sends uplink data in the case that the access network device configures multiple sets of configuration authorization parameters for the terminal. It should be noted that, when the access network device configures multiple sets of configuration authorization parameters for the terminal, in addition to sending the uplink data by using the method shown in fig. 4 or fig. 6, the terminal may also send the uplink data by using the following method:
for each set of configuration authorization parameters, the terminal determines whether the time unit indicated by each set of configuration authorization parameter terminal corresponds to the time unit used for sending the downlink data in the COT period, finds out some configuration authorization parameters of the time unit used for sending the downlink data in the COT period, which do not correspond to the indicated time unit, from at least two sets of configuration authorization parameters, and sends the uplink data in any time unit of the time units indicated by the configuration authorization parameters.
In contrast, the access network device may also determine whether the time unit indicated by each set of terminal for configuring authorization parameters corresponds to the time unit used for sending the downlink data during the COT, find some configuration authorization parameters of the time unit used for sending the downlink data during the COT, which does not correspond to the indicated time unit, from the at least two sets of configuration authorization parameters, and receive the uplink data in the time unit indicated by the configuration authorization parameters.
In yet another possible solution, the following first delay rule may also be preconfigured: and sending uplink data on a second time unit after the first time unit indicated by the configuration authorization parameter, wherein a starting symbol of the second time unit is spaced from a starting symbol of the first time unit by M symbols, where M may be the number of symbols spaced between the starting symbol of the transmission unit where the first time unit indicated by the configuration authorization parameter is located and the starting symbol of the COT, and M is a positive integer. When the terminal sends the uplink data, the number M of symbols spaced between the start symbol of the transmission unit in which the first time unit indicated by the configuration authorization parameter is located and the start symbol of the COT may be obtained according to the first delay rule, and the uplink data is sent in the second time unit after the first time unit indicated by the configuration authorization parameter according to the obtained M, so as to avoid collision with the time unit for sending the downlink data during the COT. On the access network device side, the access network device may also receive the uplink data on a second time unit after the first time unit indicated by the configuration authorization parameter, following the first delay rule. Specifically, the implementation process is shown in fig. 8.
Fig. 8 is a further resource allocation method provided in the embodiment of the present application, and as shown in fig. 8, the method may include:
step 801: and the access network equipment configures the configuration authorization parameters of the terminal.
Step 801 may refer to step 401, and is not described again.
Step 802: the access network equipment determines the configuration information of the uplink and downlink frame structures of the COT.
The description of the uplink and downlink frame structure configuration information of the COT and the determination of the uplink and downlink frame structure configuration information of the COT by the access network device may refer to step 402, and are not described again.
Step 803: the terminal obtains the configuration authorization parameter configured by the access network equipment and the uplink and downlink frame structure configuration information of the COT determined by the access network equipment.
The obtaining, by the terminal, the configuration authorization parameter configured by the access network device may include: the method comprises the steps that a terminal sends an RRC establishment request to an access network device, the access network device receives the RRC establishment request and sends an RRC message to the terminal, the terminal receives the RRC message and acquires configuration authorization parameters configured by the access network device from the RRC message; wherein the RRC establishment request is used for requesting to establish RRC connection; the RRC message may include configuration authorization parameters that the access network device configures to the terminal. Or, the terminal acquires the configuration authorization parameter configured by the access network device in a manner of combining the RRC message and the DCI indication, for example: the terminal receives an RRC message which is sent by the access network equipment and comprises a plurality of sets of configuration authorization parameters, and subsequently, the terminal can also receive an activation instruction which is sent by the access network equipment through DCI and acquire two sets of configuration authorization parameters from the configuration authorization parameters contained in the RRC message according to the activation instruction; wherein the activation instruction may be used to indicate which configuration authorization parameters to activate.
The obtaining, by the terminal, the uplink and downlink frame structure configuration information of the COT determined by the access network device may include:
the access network equipment determines the COT and the uplink and downlink frame structure configuration information of the COT, and sends DCI to the terminal during the COT, wherein the DCI comprises the uplink and downlink frame structure configuration information of the COT.
Step 804: the terminal obtains the number M of spaced symbols between the starting symbol of the transmission unit where the first time unit indicated by the configuration authorization parameter is located and the starting symbol of the COT according to the configuration authorization parameter and the configuration information of the uplink and downlink frame structures of the COT, and sends uplink data on a second time unit after the first time unit indicated by the configuration authorization parameter according to the obtained M.
The transmission unit in which the first time unit indicated by the configuration authorization parameter is located may be one or more time slots, one or more subframes, or one or more frames, without limitation. The time length of the time unit is less than or equal to the time length of the transmission unit. The starting symbol of the second time unit is spaced from the starting symbol of the first time unit by M symbols, where M is an integer.
Illustratively, the obtaining, by the terminal, the number M of symbols at an interval between the starting symbol of the transmission unit in which the first time unit indicated by the configuration authorization parameter is located and the starting symbol of the COT according to the configuration authorization parameter and the configuration information of the uplink and downlink frame structures of the COT may include:
the terminal determines a transmission unit where a first time unit indicated by an authorization configuration parameter is located and an initial symbol of the transmission unit according to the first delay rule and the configuration authorization parameter, and determines the initial symbol of the COT according to the uplink and downlink frame structure configuration information of the COT; and calculating the number M of the symbols at the interval between the initial symbol of the transmission unit and the initial symbol of the COT.
The first delay rule may be pre-stored in the access network device and the terminal; or, the first delay rule is set by the access network device and configured to the terminal in a static or semi-static manner, such as: and carrying the first delay rule in an RRC message and sending the RRC message to the terminal and the like. It should be noted that, in this embodiment of the present application, M specified in the first delay rule is not limited to the number of symbols spaced between the start symbol of the transmission unit where the time unit is located and the start symbol of the COT, and M may also have other values, for example: m may be a fixed value.
For example, as shown in fig. 9, the configuration authorization parameters configured by the access network device to the terminal are: the GF parameter 1, the symbol used for transmitting uplink data and indicated by the GF parameter 1 is symbol 6, and 6 symbols are spaced between the starting symbol of the slot where the symbol 6 is located and the starting symbol of the COT, so that the terminal may transmit uplink data on the 6 th symbol after the symbol 6.
Step 805: the access network equipment obtains the number M of spaced symbols between the initial symbol of the transmission unit where the first time unit indicated by the configuration authorization parameter is located and the initial symbol of the COT according to the configuration authorization parameter and the configuration information of the uplink and downlink frame structures of the COT, and receives uplink data on a second time unit after the first time unit indicated by the configuration authorization parameter according to the obtained M.
The process of obtaining, by the access network device, the number M of symbols at intervals between the start symbol of the transmission unit in which the first time unit indicated by the configuration authorization parameter is located and the start symbol of the COT according to the configuration authorization parameter and the configuration information of the uplink and downlink frame structures of the COT may refer to step 804, and is not described again.
It should be noted that the priority of the manner in which the terminal sends the uplink data according to the first preset rule is lower than the priority of the manner in which the terminal sends the uplink data according to the DCI instruction of the access network device in the embodiment corresponding to fig. 4 or fig. 6, and when the first preset rule and the time unit that the access network device indicates to the terminal through the DCI for sending the uplink data coexist, if the second time unit determined by the terminal according to the first preset rule is different from the time unit that the access network device notifies the terminal through the DCI, the terminal sends the uplink data according to the DCI instruction.
Based on the method shown in fig. 8, the terminal may obtain the number M of symbols spaced between the start symbol of the transmission unit where the first time unit indicated by the configuration authorization parameter is located and the start symbol of the COT, and send the uplink data in the second time unit after the first time unit indicated by the configuration authorization parameter according to the obtained M, and meanwhile, the access network device also obtains the number M of symbols spaced between the start symbol of the transmission unit where the first time unit indicated by the configuration authorization parameter is located and the start symbol of the COT, and receives the uplink data in the second time unit after the first time unit indicated by the configuration authorization parameter according to M, thereby avoiding a time point when the terminal sends the uplink data colliding with a time point when the access network device sends the downlink data.
In another possible scheme, the terminal may also send uplink data according to the configuration authorization parameter configured by the access network device, for example: if the time unit indicated by the configuration authorization parameter corresponds to a time unit used for transmitting downlink data during the COT, the uplink data is not transmitted on the time unit indicated by the configuration authorization parameter, but the uplink data is transmitted on an Nth time unit after the time unit indicated by the configuration authorization parameter, wherein N is a positive integer, the Nth time unit is different from the time unit used for transmitting the downlink data during the COT, and on the contrary, if the time unit indicated by the configuration authorization parameter does not correspond to the time unit used for transmitting the downlink data during the COT, the terminal transmits the uplink data on the time unit so as to avoid the conflict with the time unit used for transmitting the downlink data during the COT. Specifically, the implementation process is shown in fig. 10.
Fig. 10 is a further resource allocation method provided in the embodiment of the present application, and as shown in fig. 10, the method may include:
step 1001: and the access network equipment configures the configuration authorization parameters of the terminal.
Step 1001 may refer to step 801, which is not described again.
Step 1002: the access network equipment determines the configuration information of the uplink and downlink frame structures of the COT.
Step 1002 can refer to step 802, which is not described again.
Step 1003: the terminal obtains the configuration authorization parameter configured by the access network equipment and the uplink and downlink frame structure configuration information of the COT determined by the access network equipment.
Step 1003 can be described with reference to step 803, and is not described again.
Step 1004: the terminal determines whether the time unit indicated by the configuration authorization parameter corresponds to the time unit used for sending downlink data in the COT period, and if so, executes step 1005-step 1006; otherwise, step 1007-step 1008 are executed.
Step 1005: the terminal sends uplink data on the Nth time unit after the time unit indicated by the configuration authorization parameter; and the Nth time unit corresponds to the same time unit used for sending the uplink data in the COT period or the same flexibly configured time unit.
Step 1006: and the access network equipment receives the uplink data at the Nth time unit after the time unit indicated by the configuration authorization parameter.
Before the access network device performs step 1006, the access network device may also determine whether the time unit indicated by the configuration authorization parameter corresponds to the time unit used for sending the downlink data during the COT, and perform step 1006 when it is determined that the time unit indicated by the configuration authorization parameter corresponds to the time unit used for sending the downlink data during the COT, otherwise, perform step 1008.
Step 1007: and the terminal sends uplink data on the time unit indicated by the configuration authorization parameter.
Step 1008: and the access network equipment receives the uplink data on the time unit indicated by the configuration authorization parameter.
For example, in this embodiment of the present application, the nth time unit may be a time unit that is different from a time unit used for transmitting downlink data during a COT and occurs for the first time after the time unit indicated by the configuration authorization parameter, and the nth time unit may correspond to a time unit used for transmitting uplink data during the COT or a flexibly configured time unit.
For example, as shown in fig. 11, the configuration authorization parameters configured by the access network device to the terminal are: if the GF parameters 1 and the symbol used for transmitting uplink data indicated by the GF parameter 1 is symbol 6, and symbol 6 corresponds to a symbol used for transmitting downlink data during the COT, the terminal transmits uplink data on a symbol (for example, symbol 9 in fig. 11) corresponding to a flexibly configured symbol appearing first during the COT after symbol 6, or transmits uplink data on a symbol (for example, symbol 10 in fig. 11) corresponding to a symbol used for transmitting uplink data appearing first during the COT after symbol 6.
Based on the method shown in fig. 10, the terminal may determine whether the time unit indicated by the configuration authorization parameter corresponds to a time unit used for transmitting downlink data during the COT, and if so, the terminal does not transmit uplink data on the time unit, but transmits uplink data on the nth time unit after the time unit, which is the same as the time unit used for transmitting uplink data during the COT or the flexibly configured time unit; otherwise, the terminal sends the uplink data on the time unit, so that the conflict between the time point when the terminal sends the uplink data and the time point when the access network equipment sends the downlink data can be avoided.
