It is to be illustrated by taking the interaction of any one UE and base station in communication system shown in Fig. 2 as an example, including such as shown in figure 4, being the flow diagram of communication means provided by the embodiments of the present application Lower step:
S401, UE send access lead to base station using the type of coding that the UE is supported.
Wherein, the type of coding which supports may be one, it is also possible to which multiple, the embodiment of the present application is not especially limited this.
Specifically, UE sends access lead to base station using the type of coding that the UE is supported, may include:
The corresponding relationship of UE acquisition access lead and type of coding；According to the corresponding relationship, the corresponding access lead of type of coding that UE is supported is sent to base station using the type of coding that UE is supported.
Wherein, the corresponding relationship of access lead and type of coding may be to be stored in advance in UE, be also likely to be UE receive base station using mark from a variety of type of codings to the UE access lead sent and type of coding corresponding relationship after, according to the corresponding relationship of the mark of the access lead and type of coding, save the corresponding relationship of the access lead and type of coding, the mark of the access lead uniquely corresponds to an access lead, which includes at least one of the type of coding that UE is supported.The embodiment of the present application is not especially limited the UE corresponding relationship for how obtaining the access lead and type of coding.
Wherein, the corresponding relationship of access lead and type of coding specifically can be the corresponding relationship of access lead sequence and type of coding, alternatively, the corresponding relationship of access lead mark and type of coding, the embodiment of the present application are not especially limited this.It is illustrated so that the corresponding relationship of access lead and type of coding is specifically corresponding relationship of the access lead mark with type of coding as an example below, may there is the following two kinds situation.
Illustratively, assuming that the communication means is applied particularly to random access procedure competition-based, [0 is defined in existing protocol, A) the Preamble ID in section distributes to random access competition-based and uses, the Preamble ID in the section [A, C] is distributed to based on non-competing random access use.That is, the range of Preamble ID is 0~C, then in the embodiment of the present application:
In a kind of possible implementation, corresponding relationship of the access lead with the type of coding of random access competition-based and based on non-competing random access can be as shown in Table 1:
Table one
That is, in the embodiment of the present application, thus it is possible to vary the demarcation interval of Preamble ID in existing protocol.It explicitly defines in the protocol, the range of preamble ID is repartitioned into different groups, each group carries out random access for different types of UE.Such as, in Table 1, define [0, x1) the Preamble ID in section is for supporting low-density checksum (Low-Density Parity-Check, LDPC) the UE access encoded, [x1, x2) the UE access that the Preamble ID in section is used to that Turbo to be supported to encode, [x2, x3) the Preamble ID in section is used to support the UE access of Polar coding and Turbo coding, the Preamble ID in the section [x3, C] use based on non-competing random access for the UE of various abilities.Under the scene, the corresponding relationship of above-mentioned access lead and type of coding be usually UE receive base station using mark from a variety of type of codings to the UE access lead sent and type of coding corresponding relationship after, according to the corresponding relationship of the mark of the access lead and type of coding, it is stored in UE.That is, before UE sends access lead to base station using the type of coding that the UE is supported, further include: UE receives base station and uses a variety of type of codings to the mark of the UE access lead sent and the corresponding relationship of type of coding, the mark of the access lead uniquely corresponds to an access lead, which includes at least one of the type of coding that the UE is supported；In turn, UE saves the corresponding relationship of access lead and type of coding according to the mark of the access lead and the corresponding relationship of type of coding.
After UE obtains the corresponding relationship, the corresponding access lead of type of coding that UE is supported can be sent to base station using the type of coding that UE is supported according to the corresponding relationship.Such as, it is assumed that the UE supports LDPC coding, then according to table one, [0, x1) the Preamble ID in section is for branch Hold the UE access of LDPC coding, therefore, the type of coding that UE can be supported using UE, select one [0, x1) access lead in section carries out random access.
It should be noted that, above-mentioned table one is merely exemplary to be illustrated so that LDPC coding, Turbo coding and Polar encode three kinds of codings as an example, certainly there is likely to be other coding modes, or there is likely to be others to be grouped situation, and the embodiment of the present application is not especially limited this.In addition, the value of above-mentioned interval endpoint x1, x2 and x3 can be identical with the value of interval endpoint A in existing protocol, can also be different, the embodiment of the present application is not especially limited this.
In a kind of possible implementation, corresponding relationship of the access lead with the type of coding of random access competition-based and based on non-competing random access can be as shown in Table 2:
Table two
I.e., in the embodiment of the present application, the demarcation interval of random access and the Preamble ID based on non-competing random access competition-based in existing protocol can not be changed, but consultation defines a kind of essential coding mode, such as LDPC coding, it is desirable that UE and base station are all supported, and define [0, A) the Preamble ID in section is used for random access competition-based, and the Preamble ID in the section [A, C] is used for based on non-competing random access.Due to [A, C] section preamble ID be by base station control distribute, so base station can be in [A, C] in divide a segment limit and do random access competition-based to the UE for not supporting LDPC to encode and use, such as [A, y1) section is done random access competition-based to the UE for only Turbo being supported to encode and is used, [y1, y2) section is to branch The UE for holding Turbo coding and Polar coding does random access use competition-based.And the preamble ID in the section [y2, C] use based on non-competing random access for the UE of various abilities.Under the scene, the corresponding relationship of above-mentioned access lead and type of coding is usually to be stored in advance in UE, for example, support Turbo coding UE in need to configure [A, y1) section preamble ID be used for support Turbo encode UE access corresponding relationship；Support Turbo coding and Polar coding UE in need to configure [y1, y2) section preamble ID be used for support Turbo coding and Polar coding UE access corresponding relationship.That is, under the scene, for the UE for not supporting LDPC to encode, base station can negotiate or arrange in advance preamble ID with the UE, and UE obtains access lead and the corresponding relationship of type of coding specifically includes: UE obtains the corresponding relationship of the access lead and type of coding that are stored in advance in the UE.
After UE obtains the corresponding relationship, the corresponding access lead of type of coding that UE is supported can be sent to base station using the type of coding that UE is supported according to the corresponding relationship.Such as, assuming that the UE supports Turbo coding, then according to table two, [A, y1) section and [y1, y2) the UE access that the Preamble ID in section is used to that Turbo to be supported to encode, therefore, the type of coding that UE can be supported using UE, selection one is in [A, y1) section or [y1, y2) section access lead carry out random access.
It is illustrated so that LDPC coding, Turbo coding and Polar encode three kinds of codings as an example it should be noted that above-mentioned table two is merely exemplary, certainly there is likely to be other coding modes, the embodiment of the present application is not especially limited this.
S402, base station receive the access lead that UE is sent.
S403, base station determine the type of coding of UE support according to the access lead of the UE.
Specifically, base station determines the type of coding that UE is supported according to the access lead of the UE, it may include: the mark that base station determines the access lead of the UE according to the access lead of the UE；The type of coding that the UE is supported is determined according to the corresponding relationship of the mark and type of coding of the mark of the access lead of the UE and access lead.
Wherein, the corresponding relationship of the mark of the access lead and type of coding can be with reference to the corresponding relationship of access lead and type of coding in above-mentioned steps S401, and details are not described herein again.
S404, base station determine the first type of coding according to the type of coding that UE is supported.
Wherein, which may include a type of coding, also may include multiple type of codings, and the embodiment of the present application is not especially limited this.
S405, base station send access response to UE, and access response is encoded using the first type of coding.
S406, UE receive the access response that base station is sent.
Illustratively, assuming that the mark of access lead and the corresponding relationship of type of coding are as shown in Table 1, the access lead that base station receives is identified as P1, x2≤P1 < x3, then base station can the corresponding relationship according to shown in table one, determine UE support Turbo coding and Polar coding.Assuming that base station determines the first type of coding according to the type of coding that UE is supported as Turbo coding, then base station can encode access response using Turbo coding.In this way, since access response is the first type of coding coding determined using the type of coding supported according to UE, UE can be with successfully decoded, and then UE may be successfully accessed after UE receives access response.
Alternatively, illustrative, it is assumed that the mark of access lead and the corresponding relationship of type of coding are as shown in Table 2, the access lead that base station receives is identified as P2, y1≤P2 < y2, then base station can the corresponding relationship according to shown in table two, determine UE support Turbo coding and Polar coding.Assuming that base station determines that the first type of coding is that Turbo coding and Polar are encoded according to the type of coding that UE is supported, then base station can encode access response using Turbo coding and Polar coding.In this way, since access response is the first type of coding coding determined using the type of coding supported according to UE, UE can be with successfully decoded, and then UE may be successfully accessed after UE receives access response.In this way, base station can distinguish the UE of different coding type under the premise of not modifying agreement, it is ensured that the UE of different coding ability can be accessed normally.
In communication means provided by the embodiments of the present application, UE sends access lead to base station using the type of coding that UE is supported, after base station receives the access lead, the type of coding which supports is determined according to the access lead, and then the first type of coding is determined according to the type of coding that UE is supported.Then, base station sends access response to UE, and access response is encoded using the first type of coding.That is, in communication means provided by the embodiments of the present application, UE is sent to base station after access lead, base station can know the type of coding that the UE is supported, and then the first type of coding can be determined based on the UE type of coding supported, after encoding using the first type of coding to access response, access response is sent to UE.In this way, UE receive the access response after, by It is consistent with the coding mode of UE in base station, therefore UE can be with successfully decoded, and then UE may be successfully accessed.
