In yet another example, by taking the characteristic information of terminal includes the requested main business type of terminal as an example.Illustratively; type of service includes enhanced mobile broadband (enhanced Mobile Broadband; eMBB) business, large-scale machines communicate (massive Machine-type Communication; mMTC) business, highly reliable low time delay communication (Ultra-relaible and Low Latency Communication, URLLC) business etc..When the requested type of service of terminal is only a kind of, this kind of type of service is the requested main business type of terminal；When the requested type of service of terminal is a variety of, the maximum type of service of portfolio is as the requested main business type of terminal in the multiple business type.For example, access network equipment is that terminal configures less HARQ process number if the requested main business type of terminal is time delay sensitive type business (such as URLLC business)；If the requested main business type of terminal is time delay tolerance type business (such as eMBB business), access network equipment is that terminal configures more HARQ process number.In practical applications, the first corresponding relationship can be prestored in access network equipment, first corresponding relationship includes the corresponding relationship between different types of service and different HARQ process numbers, and access network equipment inquires the HARQ process number that above-mentioned first corresponding relationship is determined as terminal configuration.
Access network equipment has been described above according to the characteristic information of terminal, has configured HARQ process number n for terminal.(Pre-determined) at least one candidate's HARQ process number can be predefined in other possible embodiments, in access network equipment.It is closed for example, configuring candidate's HARQ process manifold in access network equipment, includes several candidate's HARQ process numbers such as 6,8,10,12 in the set.Access network equipment selects candidate's HARQ process number to be allocated to terminal from least one predefined candidate's HARQ process number (namely above-mentioned candidate's HARQ process manifold is closed).
In addition, it is that terminal configures HARQ process number n that access network equipment, which can be sent by DCI to terminal, can also be sent by high-level signaling to terminal is that terminal configures HARQ process number n.
Step 202, m HARQ process in n HARQ process is distributed into the carrier wave that terminal is currently supported, wherein n >=m >=1, n, m are positive integer.
For carrier aggregation scene, the carrier wave that terminal is currently supported includes multiple carrier waves that the terminal works as pre-polymerization.Access network equipment is after configuring HARQ process number for terminal, for the corresponding HARQ process number of each carrier wave initial configuration of terminal polymerization.M HARQ process in n HARQ process is distributed to each carrier wave of terminal polymerization by access network equipment.That is, the sum of the HARQ process number that each carrier wave of terminal polymerization is assigned is m.Also, it in each carrier wave of terminal polymerization, is assigned there are at least two carrier waves
HARQ process number is identical or different.For example, the HARQ process number that access network equipment is terminal configuration is 20, the number of carrier wave of terminal polymerization is 3, and access network equipment is that the HARQ process number of 3 carrier waves distribution is respectively 3,8,8.
Optionally, in each carrier wave initialization distribution HARQ process polymerizeing for terminal, each carrier wave is assigned at least one HARQ process.
Optionally, for carrier aggregation scene, step 202 includes following several sub-steps:
1, the characteristic information of each carrier wave of terminal polymerization is obtained；
2, according to the characteristic information of each carrier wave of terminal polymerization, m HARQ process in n HARQ process is distributed to each carrier wave of terminal polymerization.
The characteristic information of carrier wave refers to the information for being used to indicate the feature of carrier wave.Illustratively, the characteristic information of carrier wave comprises at least one of the following: the frequency band where main business type that underlying parameter collection, carrier wave used by carrier wave are carried, carrier wave.The characteristic information of each carrier wave of terminal polymerization can be reported, or voluntarily obtained by access network equipment according to the configuration information of communication system by terminal active reporting to access network equipment after can also issuing instruction to terminal from access network equipment.
In one example, used by the characteristic information of carrier wave is carrier wave for underlying parameter collection.It includes TTI, subcarrier spacing, the parameters such as symbol quantity for including in each TTI that underlying parameter used by carrier wave, which is concentrated,.By taking TTI as an example, for each carrier wave of terminal polymerization, access network equipment selects at least one HARQ process to distribute to the carrier wave according to the corresponding TTI of the carrier wave from above-mentioned n HARQ process.It wherein, is the HARQ process number TTI correlation corresponding with carrier wave of carrier wave distribution.That is, the corresponding TTI of carrier wave is longer, the HARQ process number for carrier wave distribution is more；The corresponding TTI of carrier wave is shorter, and the HARQ process number for carrier wave distribution is fewer.In practical applications, the second corresponding relationship can be prestored in access network equipment, second corresponding relationship includes the corresponding relationship between different TTI and different HARQ process numbers, and access network equipment inquires the HARQ process number that above-mentioned second corresponding relationship is determined as each carrier wave distribution of terminal.
In another example, by taking the main business type that the characteristic information of carrier wave is carried by carrier wave as an example.When the type of service that carrier wave is carried is only a kind of, this kind of type of service is the main business type that carrier wave is carried；When the type of service that carrier wave is carried is a variety of, the maximum type of service of portfolio is carried as carrier wave in the multiple business type main business type.For each carrier wave of terminal polymerization, the main business type that access network equipment is carried according to the carrier wave selects at least one HARQ process to distribute to the carrier wave from above-mentioned n HARQ process.For example, access network equipment is that the carrier wave distributes less HARQ process number if the main business type that carrier wave is carried is time delay sensitive type business；If carried
The main business type that wave is carried is time delay tolerance type business, then access network equipment is that the carrier wave distributes more HARQ process number.In practical applications, third corresponding relationship can be prestored in access network equipment, the third corresponding relationship includes the corresponding relationship between different types of service and different HARQ process numbers, and access network equipment inquires the HARQ process number that above-mentioned third corresponding relationship is determined as each carrier wave distribution of terminal.
In yet another example, by taking the frequency band where the characteristic information of carrier wave is carrier wave as an example.For each carrier wave of terminal polymerization, access network equipment selects at least one HARQ process to distribute to the carrier wave according to the frequency band where the carrier wave from above-mentioned n HARQ process.In general, the corresponding frequency size of frequency band and the corresponding TTI negative correlation of carrier wave where carrier wave, and it is the HARQ process number TTI correlation corresponding with carrier wave of carrier wave distribution.That is, the corresponding frequency size of frequency band where carrier wave is smaller, the corresponding TTI of carrier wave is longer, and the HARQ process number for carrier wave distribution is more；The corresponding frequency size of frequency band where carrier wave is bigger, and the corresponding TTI of carrier wave is shorter, and the HARQ process number for carrier wave distribution is fewer.In practical applications, the 4th corresponding relationship can be prestored in access network equipment, 4th corresponding relationship includes the corresponding relationship between different frequency band and different HARQ process numbers, and access network equipment inquires the HARQ process number that above-mentioned 4th corresponding relationship is determined as each carrier wave distribution of terminal.
Above with respect to carrier aggregation scene, the characteristic information for each carrier wave that access network equipment polymerize according to terminal is described, configures corresponding HARQ process number for each carrier wave.In other possible embodiments, in each carrier wave initial configuration HARQ process number polymerizeing to terminal, m HARQ process in n HARQ process is averagely allocated to each carrier wave of terminal polymerization by access network equipment.
For non-carrier aggregation scene, the quantity for the carrier wave that terminal is currently supported is 1, the different underlying parameter collection of the carrier multiplexing multiple groups.M HARQ process in above-mentioned n HARQ process is distributed to the carrier wave by the access network equipment underlying parameter collection currently employed according to the carrier wave.
By taking TTI as an example, access network equipment selects at least one HARQ process to distribute to the carrier wave according to the corresponding TTI of the carrier wave from above-mentioned n HARQ process.It wherein, is the HARQ process number TTI correlation corresponding with carrier wave of carrier wave distribution.That is, the corresponding TTI of carrier wave is longer, the HARQ process number for carrier wave distribution is more；The corresponding TTI of carrier wave is shorter, and the HARQ process number for carrier wave distribution is fewer.In practical applications, the second corresponding relationship can be prestored in access network equipment, second corresponding relationship includes the corresponding relationship between different TTI and different HARQ process numbers, and access network equipment inquires the HARQ process number that above-mentioned second corresponding relationship is determined as carrier wave distribution.
The above-mentioned HARQ process for carrier wave configuration can be described as shared HARQ process, and shared HARQ process refers to that the HARQ process for carrier wave dynamic configuration, the corresponding shared HARQ process of carrier wave according to circumstances can dynamically change.Correspondingly, access network equipment is that carrier wave configures shared HARQ process number, shares HARQ
Process number refers to the quantity of shared HARQ process, and the corresponding shared HARQ process number of carrier wave according to circumstances can dynamically change.
In addition, access network equipment can send the HARQ process number for the carrier wave initial configuration currently supported for terminal by DCI to terminal, the HARQ process number for the carrier wave initial configuration that currently support for terminal can also be sent to terminal by high-level signaling.
Access network equipment can dynamically be adjusted to the HARQ process number for the carrier wave distribution that terminal is currently supported after the corresponding HARQ process number of carrier wave initial configuration currently supported for terminal according to the actual situation.Further include following steps after above-mentioned steps 102: when the carrier wave that terminal is currently supported changes, access network equipment is adjusted to the HARQ process number for the carrier wave distribution that terminal is currently supported.
For carrier aggregation scene, explanation is introduced by following several examples.
In one example, when the feature of the carrier wave of terminal polymerization changes, access network equipment is adjusted to the HARQ process number of each carrier wave distribution of terminal polymerization.The feature of carrier wave comprises at least one of the following: the frequency band where main business type that underlying parameter collection, carrier wave used by carrier wave are carried, carrier wave.For example, access network equipment increases the HARQ process number distributed for the carrier wave when the main business type that a certain carrier wave is carried becomes time delay tolerance type business from time delay sensitive type business.In another example access network equipment is reduced to the HARQ process number of carrier wave distribution when the main business type that a certain carrier wave is carried becomes time delay sensitive type business from time delay tolerance type business.For another example access network equipment is reduced to the HARQ process number of carrier wave distribution when the corresponding TTI of a certain carrier wave shortens.
In another example, when the number of carrier wave of terminal polymerization changes, access network equipment is adjusted to the HARQ process number of each carrier wave distribution of terminal polymerization.The carrier wave of polymerization newly-increased for terminal, access network equipment are that the carrier wave distributes HARQ process number.The carrier wave of polymerization newly-increased for terminal selects at least one HARQ process to distribute to the carrier wave if it is there are also unappropriated HARQ processes in the HARQ process of terminal configuration from unappropriated HARQ process；If it is there is no unappropriated HARQ process in the HARQ process of terminal configuration, at least one HARQ process is selected to distribute to the carrier wave from the HARQ process for distributing to other carrier waves.The carrier wave of polymerization is reduced for terminal, the HARQ process for distributing to the carrier wave can be distributed to other carrier waves, the HARQ process for distributing to the carrier wave can also be reclaimed for subsequent allocations by access network equipment.
For non-carrier aggregation scene, explanation is introduced by following examples.
When the underlying parameter collection used by this carrier wave that terminal is currently supported changes, access network equipment is adjusted to the HARQ process number of carrier wave distribution.By taking TTI as an example, when the corresponding TTI of the carrier wave shortens, access network equipment is reduced to the HARQ process number of carrier wave distribution；As the corresponding TTI of the carrier wave
