Fig. 1 is the schematic interaction figure of relevant wireless communications method 100.

UE is receiving wireless heterogeneous networks (RRC, Radio Resource Control) connection establishment message After, it is possible to start to report RI.Wherein wireless heterogeneous networks connection establishment message is abbreviated as RRCConnectionSetup message.Particularly give the correct time and need quarter to see RI parameter configuration situation.Current association View defines the computational methods of RI cycle and biasing.ENB is in the cycle and biasing having known that RI sends After, it becomes possible to determine and need in which moment to go to resolve RI, in order to obtain the value etc. of the RI that UE reports In how much, thus further determine that base station sends data with which kind of form of codewords.RI reports and is divided into 1 bit Reporting and report with 2 bits, the payload bit wide of RI and antenna port number, UE are in downlink spatial multiplexing The maximum number of plies supported is relevant.Such as shown in table 1 below:

Table 1

Wherein, UE is supported in downlink spatial multiplexing the maximum number of plies and UE kind (Category) are straight Connect relevant, see Current protocol, as shown in table 2 below:

Table 2

UE kind	The maximum number of plies that downlink spatial multiplexing is supported
		1	1
2	2
		3	2

		5	4

User equipment class, is slightly written as UE kind, different because of different UE.

Can release from Tables 1 and 2, the payload bit wide that RI reports and antenna port number, UE kind Class has relation.UE kind is currently included 5 kinds.

UE there will be UE and ENB in access procedure and understands differently the payload bit wide of RI cause, Causing solution not go out RI or decoded RI inconsistent, concrete example is as shown in Figure 1.

Before Stochastic accessing, UE has known the UE kind of oneself.For convenience of description, set UE herein UE kind be 5.

Now ENB is temporarily without UE kind, can choose at random a UE kind.

Step 120, UE sends random access lead code (English for preamble) to ENB.

Step 125, after ENB receives random access lead code, sends accidental access response (English to UE Literary composition is RAR, Random Access Response).

Step 130, UE receives accidental access response, to ENB send wireless heterogeneous networks (RRC, Radio Resource Control) connection request (English is RRCConnectionRequest) message.

Step 135, ENB receives wireless resource control connection request, and (English is RRCConnectionRequest), after message, wireless heterogeneous networks connection establishment is sent to UE (English For RRCConnectionSetup) message.Wireless heterogeneous networks connection establishment message carries antenna port Number.For the convenience of explanation, antenna port number is set to 4 ports herein.

Step 140, UE determines the payload bit wide of RI.

UE known UE kind is 5, determines that according to table 2 the maximum number of plies of support is 4.Wireless knowing After port number is 4 ports, according to table 1, UE determines that the payload bit wide of RI sent to ENB is 2。

Step 145, ENB determines the payload bit wide of RI.

By choosing at random, it is assumed that the UE kind that ENB uses is 1, is 4 based on antenna port number The information such as port, determine that the payload bit wide of RI is 1, and resolve, with this, the RI that UE reports.

Step 150, the payload bit wide determined according to UE, UE reports RI to ENB.

Step 155, the payload bit wide determined according to ENB, ENB receives RI, RI and reports failure.

Occurring in that the payload bit wide of the RI that ENB and UE use is inconsistent, ENB cannot correctly solve Separating out RI, namely RI reports failure, thus affects follow-up flow process.

A kind of possible situation, causes access delay to increase.Specifically, owing to RI reports failure, The RI causing UE and ENB to use is different, follow-up report carry the packet with road CQI and can solve Analysis mistake, packets need could be successful through retransmitting, and which increases access delay.

In correlation technique, UE reports RI to send wireless capability message query messages early than base station to UE.When After reporting RI failure, the nothing of the response wireless capability message query messages that base station can be sent by UE Line capability information message knows UE kind, thus knows RI.The embodiment of the present invention solves logical in base station Crossing before wireless capability message message knows RI, UE and base station use the payload bit wide of RI inconsistent The problem of the access delay brought.

For the problems referred to above, it follows that a kind of method embodiments providing radio communication.? In context, introduce the user equipment class specified, it is intended that user equipment class also can slightly be written as specifying UE kind, be not known by the UE kind of described UE for described base station before, described base station and described UE It is designated the UE kind used.Such as, before base station is not known by UE kind, use UE for needs The network element of kind, such as UE and base station, it is intended that the UE kind of use.Optionally, it is intended that UE Kind is identical for UE and base station, can be specified by agreement or base station specifies one UE kind makes for realizing with this base station for UE simultaneously.

Such as, it is intended that UE kind can be default UE kind, be such as arranged on base station or mobile phone Protocol profile in.When base station and mobile phone have known the UE kind specified the most, can be without increasing Add cell of eating dishes without rice or wine and carry the UE kind specified, use the UE kind specified and then decode RI smoothly.

And for example, it is also possible between UE and base station, known, by a square tube, the UE kind that the opposing party should specify. In the method, need by increasing cell or revising the physical significance of former message and carry the UE kind specified Class.When base station has known the UE kind specified, can by UE send RAR message or RRCConnectionSetup message, above-mentioned message carries this UE kind specified, thus UE is known The UE kind specified.The corresponding UE that works as has known the UE kind specified, can be by sending out to base station Sending RRCConnectionRequest message, this message carries the UE kind specified, thus base station is known The UE kind specified.This mode makes UE and base station be not based on the UE kind of UE, but base In an interim UE kind, it is also possible to determine the payload bit wide of identical RI.

It should be noted that for particular UE, it is intended that UE kind can be differently configured from UE kind.Ratio In the example above, default UE kind, UE or base station notifies to the UE kind of the opposing party after specifying May not be the true UE kind of this particular UE, and be only can be temporarily applied to determine that RI is effective The UE kind of load bit wide, is similar to a kind of virtual UE kind.

The embodiment of the present invention is preferably used the method for default UE kind, is not thus increasing any eating dishes without rice or wine In the case of cell, optimize the order of message, thus shorten access delay.In ensuing embodiment, UE and base station have known the UE kind specified, the method known as it was previously stated, the embodiment of the present invention not Limit.
