Wherein, by taking resource is time resource as an example, UE sends the first channel in temporal frequency used in corresponding first channel of each coverage enhancement grade in multiple coverage enhancement grades used in the first transmission.UE can determine the time resource that the corresponding second channel transmission of each coverage enhancement grade is used in multiple coverage enhancement grades.If corresponding first transmission of multiple coverage enhancement grades uses code division multiplexing, UE determines the corresponding second channel transmission of+1 coverage enhancement grade of jth is used in multiple coverage enhancement grades resource after the corresponding second channel transmission of j-th of coverage enhancement grade resource used.The corresponding second channel transmission of two neighboring coverage enhancement grade resource used is time division multiplexing in i.e. multiple coverage enhancement grades.+ 1 coverage enhancement grade of jth is adjacent with j-th of coverage enhancement grade, and the corresponding second channel transmission of+1 coverage enhancement grade of jth resource used is after the corresponding second channel transmission of j-th of coverage enhancement grade resource used in multiple coverage enhancement grades.Also, in embodiments of the present invention, L_jIt is the transmission opportunity number for the first channel for including in preset time span under j-th of coverage enhancement grade.The L of second channel_jResource used in a transmission opportunity is the corresponding L of j-th of coverage enhancement grade_jA second channel transmission resource used.The L of second channel_jResource used in a transmission opportunity is time-multiplexed.

Further, in some embodiments of the invention, initial time resource can determine in the following way in second channel transmission time resource used, corresponding first transmission of N number of coverage enhancement grade uses code division multiplexing, in preset time span, the starting subframe subframe of the corresponding second channel of first transmission opportunity of corresponding first transmission of i-th of coverage enhancement grade_iMeet following relationship:

By the above embodiments description of the invention it is found that the first UE resource according to used in the first transmission first determines second channel transmission resource used, wherein resource includes one of coverage enhancement grade, frequency resource, time resource or a variety of.Then the first UE receives the second channel that base station is sent in the second channel transmission determined resource used.Since the first UE can determine second channel transmission resource used according to resource used in the first transmission, thus solves the problems, such as the determination of second channel transmission resource used, and resource described in the embodiment of the present invention includes one of coverage enhancement grade, frequency resource, time resource or a variety of, therefore it in second channel transmission coverage enhancement grade used, frequency resource, time resource, can be determined by coverage enhancement grade, frequency resource, time resource used in the first transmission.After first UE determines second channel transmission resource used, second channel is received in second channel transmission resource used.Under the scene for carrying out coverage enhancement transmission for random access response, the coverage enhancement grade that can be used according to random access channel carries out the determination of the coverage enhancement grade of random access response.

In order to facilitate a better understanding and implementation of the above scheme of the embodiment of the present invention, corresponding application scenarios are illustrated below to be specifically described.

In embodiments of the present invention, the coverage enhancement grade of random access response message is determined according to the corresponding coverage enhancement grade of random access channel resource set, the frequency resource of random access response message determines that the initial time resource of random access response message is determined according to random access channel resource set according to random access channel resource set.Here random access response message is to dispatch the control channel of accidental access response message, or carry the channel of random access response or the channel of response random access channel.Such as random access response message can be the Physical Downlink Control Channel of enhancing, or Physical Downlink Control Channel or Physical Downlink Control Channel for machine type communication.Random access channel can be Physical Random Access Channel.

The performance (such as maximum junction loss) and the performance of random access response message of random access channel itself have differences.If UE is using single receiving antenna and/or receives the bandwidth of signal in the frequency resource of very narrow (such as several Physical Resource Block or several subcarriers), can transmission belt to downlink signal cover loss.If the maximum transmission power of UE is lower (such as 20dBm), can transmission belt to uplink signal cover loss.Because random access response message is downlink signal, PRACH is uplink signal, in this way in view of single receiving antenna, the bandwidth for receiving signal, the maximum transmission power of UE these factors, so that the difference between the transmission performance of random access channel and the transmission performance of random access response message is increasingly complex.In embodiments of the present invention, the coverage enhancement grade of random access response message is determined according to the corresponding coverage enhancement grade of random access channel resource set.

In addition, the random access channel resource set of different coverage enhancement grades may use one or more of frequency division multiplexing, time division multiplexing, code division multiplexing (i.e. leader sequence multiplexing).Such as, the random access channel resource set of different coverage enhancement grades using frequency division multiplexing (or time division multiplexing, or code division multiplexing) when, the resource of the random access response message of the corresponding each coverage enhancement grade of the random access channel resource of different coverage enhancement grades can be frequency division multiplexing or time-multiplexed or code division multiplexing.A kind of simple method can be used in the embodiment of the present invention, and the frequency resource and/or initial time resource of random access response message are easily determined according to random access channel resource set.

In a kind of embodiment of the invention, the coverage enhancement grade of second channel is determined according to the coverage enhancement grade of the first channel.Usual first channel is up channel, and the first channel is down channel.Particularly, the first channel is random access channel, and second channel is the channel for carrying random access response message.Random access response message is to dispatch the control channel of accidental access response message, or carry the channel of random access response or the channel of response random access channel.Such as random access response message can be the Physical Downlink Control Channel of enhancing, or Physical Downlink Control Channel or Physical Downlink Control Channel for machine type communication.Random access channel can be Physical Random Access Channel.

It is poor according to the performance between the performance of the performance and second channel of the coverage enhancement grade of the first channel and the first channel under a kind of realization scene, determine the coverage enhancement grade of second channel.

There are performance difference between the performance of first channel and the performance of second channel, this performance difference is related to frame structure.If frame structure type is frequency division duplex, the performance difference between the performance of the first channel and the performance of second channel is A dB.Particularly, in the embodiment of the present invention, performance can be maximum link loss or signal-to-noise ratio or Signal to Interference plus Noise Ratio or coverage enhancement value.Frame structure type is time division duplex, and the performance difference between the performance of the first channel and the performance of second channel is B dB.A is not equal to B.

Assuming that it is U dB that downlink cost, which reduces the covering loss of technology bring, it is V dB that uplink cost, which reduces the covering loss of technology bring,.Then, the case where being frequency division duplex for frame structure type, the performance difference between the performance of the first channel and the performance of second channel is (A-U+V) dB.The case where being time division duplex for frame structure type, the performance difference between the performance of the first channel and the performance of second channel are (B-U+V) dB.

For example, the single reception rf chain of note (or single receiving antenna) bring downlink covering loss is C dB.It is D dB that note bandwidth, which is reduced to the loss of S2MHz bring from S1MHz,.It is E dB that single reception rf chain and bandwidth, which are reduced to the loss of S2MHz bring from S1MHz,.It is F dB that uplink power, which reduces the covering loss of bring uplink,.

Assuming that the uplink transmission power of UE does not reduce, in the case that the performance of the first channel is constant,

If second channel is only influenced by single reception rf chain (or single receiving antenna) bring downlink covering loss, the performance difference between the performance of the first channel and the performance of second channel is X=(Y-C) dB；

If second channel, which is only reduced the covering loss of bring downlink by bandwidth, to be influenced, the performance difference between the performance of the first channel and the performance of second channel is X=(Y-D) dB；

If second channel is reduced the covering loss of bring downlink and influence by single rf chain and bandwidth of receiving, the performance difference between the performance of the first channel and the performance of second channel is X=(Y-E) dB.Here, for frequency division duplex, Y is equal to A, and for time division duplex, Y is equal to B.

Assuming that the uplink transmission power (such as relative to 23dBm) of UE reduces F dB, the reduced performance of the first channel F dB:

If second channel is only influenced by single reception rf chain (or single receiving antenna) bring downlink covering loss, then the performance difference between the performance of the first channel and the performance of second channel is X=(Y-C+F) dB；

If second channel, which is only reduced the covering loss of bring downlink by bandwidth, to be influenced, then the performance difference between the performance of the first channel and the performance of second channel is X=(Y-D+F) dB；

If second channel is reduced the covering loss of bring downlink and influence by single rf chain and bandwidth of receiving, then the performance difference between the performance of the first channel and the performance of second channel is X=(Y-E+F) dB.

Wherein, in the case of being frequency division duplex for frame structure type, Y is equal to A, and in the case of being time division duplex for frame structure type, Y is equal to B.

It is related whether the uplink transmission power of the above X and UE reduces.Particularly, whether X can reduce unrelated with the uplink transmission power of UE, and X is equal to the X value for assuming to calculate when the uplink transmission power of UE does not reduce or the value equal to the X calculated when assuming that the uplink transmission power of UE reduces at this time.

In another realization scene of the invention, determines the first parameter, the rank difference between the coverage enhancement grade of second channel and the coverage enhancement grade of the first channel is determined according to X and the preset relationship of the first parameter.First parameter is to can be prespecified parameter value perhaps the first parameter is to be determined according to coverage enhancement grade or random access channel coverage enhancement grade or the first parameter is system configuration.Such as first parameter be that perhaps the first parameter is the difference of the corresponding path loss of each coverage enhancement grade or the first parameter is the corresponding coverage enhancement degree of each coverage enhancement grade for the difference of the corresponding Reference Signal Received Power of each coverage enhancement grade.The size of the first parameter is indicated with S.The rank difference between the coverage enhancement grade of second channel and the coverage enhancement grade of the first channel is indicated with d.The coverage enhancement grade of even the first channel is n, then the coverage enhancement grade of second channel is n-d.In the present invention, for a channel, number of repetition used in channel when number of repetition used in the channel is high less than covering grade when coverage enhancement grade is low.

A kind of method of determining d is to need to meet a specific inequality according to known X and S, d.For example, specific inequality are as follows:

(d × S-S/2)≤X≤d × S+S/2), or

(d × S-S/2)≤X < (d × S+S/2), or

(d × S)≤X≤(d × S+S), or

(d×S)≦X<d×S+S)。

Under a kind of realization scene, the coverage enhancement grade of second channel is determined according to the coverage enhancement grade, the performance of the first channel and the performance of second channel of the first channel.

Assuming that the performance of the first channel is M1, the performance of second channel is M2.For a UE, it is assumed that it is U dB that downlink cost, which reduces the covering loss of technology bring, and it is V dB that uplink cost, which reduces the covering loss of technology bring,.Then, for frequency division duplex system, the performance of the first channel is M1-V, and the performance of second channel is M2-U.

If the uplink transmission power of UE does not reduce, the performance of the first channel is constant.If the uplink of UE Transmission power (such as relative to 23dBm) reduces F dB: the performance of its first channel is (M1-F) dB.

If second channel is only influenced by single reception rf chain (or single receiving antenna) bring downlink covering loss, then its performance is (M2-C) dB.If down channel, which is only reduced the covering loss of bring downlink by bandwidth, to be influenced, then its performance is (M2-D) dB.If down channel is reduced the covering loss of bring downlink and influence by single rf chain and bandwidth of receiving, then its performance is (M2-E) dB.

D × S-S/2)≤Z≤(d × S+S/2), or,

(d × S-S/2)≤Z < (d × S+S/2), or

(d × S)≤Z≤(d × S+S), or

(d×S)≦Z<(d×S+S)。

Under a kind of realization scene, according to the coverage enhancement grade of the coverage enhancement grade of the first channel and prespecified determining second channel.

Assuming that the coverage enhancement grade of the first channel is n:

For tdd systems, the coverage enhancement grade of second channel is n+1, and for frequency division duplex system, the coverage enhancement grade of second channel is n.Alternatively,

If the coverage enhancement grade for tdd systems second channel is n, for frequency division duplex system, the coverage enhancement grade of second channel is n-1.Alternatively,

For tdd systems, the coverage enhancement grade of second channel is n+m, and for frequency division duplex system, the coverage enhancement grade of second channel is n+m-1, and m is a prespecified value here.Alternatively,

The coverage enhancement grade of second channel is n or n-1 or n+1.

Further, the coverage enhancement grade of second channel can also be determined according to UE type.For example, the coverage enhancement grade of the second channel of the first UE is m, then the coverage enhancement grade of the second channel of the 2nd UE is j, here j=m+k.K is a fixed integer in -2 to 2.Particularly, k=0.The coverage enhancement grade of the second channel of first UE can be determined according to the method for any one in preceding method.The coverage enhancement grade of 2nd UE can be determined according to the coverage enhancement grade of the second channel of the first UE, can also be determined according to any one method of preceding method.

Particularly, the first UE is low complex degree UE, and the 2nd UE is non-low complex degree UE.Low complex degree UE is the UE using cost reduction technology.Alternatively, low complex degree UE is reduced using uplink power, Then k=0, low complex degree UE do not use uplink power to reduce, then k=-1.

If different grades of PRACH resource uses code division multiplexing, the resource of random access response message uses frequency division multiplexing or time division multiplexing.Particularly, the resource of random access response message can be system configuration using frequency division multiplexing or time division multiplexing.Such as system is configured with different frequency resources for the random access response message of two different coverage enhancement grades, then it represents that the resource of the random access response message of the two different coverage enhancement grades uses frequency division multiplexing.Such as system is configured with identical frequency resource for the random access response message of two different coverage enhancement grades, then it represents that the resource of the random access response message of the two different coverage enhancement grades is using time division multiplexing.Alternatively, system is still time-multiplexed using the resource of a bit indication random access response message using frequency division multiplexing.Alternatively, the multiplex mode of the resource of fixed different grades of random access response message, for example, the resource of random access response message is using time division multiplexing if the random access channel resource of different coverage enhancement grades uses code division multiplexing.

When the random access channel resource of different coverage enhancement grades uses code division multiplexing, when the resource of random access response message is using time division multiplexing, the following figure gives the time resource that a specific method determines random access response message.

If a random access channel transmission opportunity of coverage enhancement grade a occupies M subframe, a random access channel chance of coverage enhancement grade b occupies N number of subframe, and wherein N is greater than M.If N is more than or equal to 2M, then in N number of subframe, the chance (each chance occupancy M subframe) that coverage enhancement grade a has L random access channel to transmit, L=ceil (N/M) or L=floor (N/M), here ceil is the function that rounds up, and floor is downward bracket function.Because the corresponding random access response message resource of the random access channel of coverage enhancement grade a and the corresponding random access response message resource of random access channel of coverage enhancement grade b be it is time-multiplexed, can specify that the corresponding random access response message resource of a random access channel chance of coverage enhancement grade b after the corresponding L random access response message resource of L random access channel chance of coverage enhancement grade a.Alternatively, can specify that the corresponding random access response message resource of a random access channel chance of coverage enhancement grade b before the corresponding L random access response message resource of L random access channel chance of coverage enhancement grade a.

As shown in Figure 4, it is to carry the channel of random access response to determine a kind of implementation schematic diagram of time resource for a kind of coverage enhancement grade according to random access channel provided in an embodiment of the present invention, figure illustrates the random access channel resource when different coverage enhancement grades using code division multiplexing, when the resource of random access response message is using time division multiplexing, the timing diagram of the time resource of random access response message is determined.In Fig. 4, the determining time resource of the corresponding random access channel chance of random access coverage enhancement grade 1 are as follows: with The corresponding random access response message of a random access channel chance of machine access channel grade 1, the time resource that the corresponding random access channel chance of random access coverage enhancement grade 1 determines are as follows: the corresponding random access response message of another random access channel chance of random access channel grade 1, the time resource that the corresponding random access channel chance of random access coverage enhancement grade 2 determines are as follows: the corresponding random access response message of a random access channel chance of random access channel grade 2, the corresponding random access response message of a random access channel chance of random access channel grade 1, the corresponding random access response message of another random access channel chance of random access channel grade 1, the corresponding random access response of a random access channel chance of random access channel grade 2 The different time is successively occupied between message in time.

In some embodiments of the present invention, in preset time span, assuming that the random access channel of shared b coverage enhancement grade uses code division multiplexing, in the coverage enhancement grade for the random access channel that specific time span can be b code division multiplexing, a random access channel chance corresponding time of the coverage enhancement grade of the random access channel of b-th of code division multiplexing.

By previous embodiment is to illustration of the invention, the random access channel resource set of different coverage enhancement grades uses hybrid multiplex mode (i.e. the combination of frequency division multiplexing, time division multiplexing, code division multiplexing), and mapping relations there are many kinds of the resource meetings of corresponding random access response message are determined according to random access channel resource.The present invention considers the reasonable connection between random access channel resource and the resource of corresponding random access response message, to simplify the resource for determining corresponding random access response message according to random access channel resource.In addition, because random access response message is downlink signal, PRACH is uplink signal, in this way in view of single receiving antenna, the bandwidth for receiving signal, the maximum transmission power of UE these factors, so that the difference between the transmission performance of random access channel and the transmission performance of random access response message is increasingly complex.The present invention proposes that specific algorithm solves the problems, such as to determine the coverage enhancement grade of random access response message according to the corresponding coverage enhancement grade of random access channel resource set by the specific difference value between the transmission performance of analysis random access channel and the transmission performance of random access response message.
