Description

Signal transmission method and terminal

The invention belongs to the field of communication technologies, and in particular to a method and a terminal for signal transmission.

In the traditional cellular communication technology, the data communication process between terminals (User Equipments, UEs) is as shown in FIG. 1. The voice, data, and other services of the two terminals pass through the base station (eNB) and the core network (service gateways) where they reside. (Serving Gateway, SGW) interacts with a Packet Data Network Gateway (PGW).

Device-to-device (D2D) communication, that is, terminal direct-through technology, refers to a method in which neighboring terminals can transmit data through a direct link within a short range without passing through a central node (ie, a base station). Forward, as shown in Figure 2.

The short-distance communication characteristics and direct communication mode of D2D technology have the following advantages: 1. The terminal short-distance direct communication mode can achieve higher data transmission rate, lower transmission delay and lower power consumption; The widely distributed user terminals in the network and the short-distance characteristics of the D2D communication link can realize efficient use of spectrum resources. 3. The direct communication method of D2D can satisfy, for example, wireless point-to-point (Point-to- Point, P2P) and other services for local data sharing needs, providing flexible and adaptable data services; 4, D2D direct communication can utilize a large number of widely distributed communication terminals in the network to expand the network coverage.

Due to the uncertainty of the location of the transmitting UE in the D2D system, for a receiving UE, when the signal transmitted by the different transmitting UE arrives at the receiving UE, the difference in path loss may be very large, resulting in a problem of in-band leakage. Far-near effect effect. Specifically, as shown in FIG. 3, for example, the receiving UE (Rx UE) is receiving the signal of the Tx UE1, and the signal strength of the channel of the Tx UE1 reaching the Rx UE is -100 dBm (dBmW) due to the influence of the channel fading. The Tx UE2 located near the Rx UE also initiates a D2D communication at the same time, and the signal strength of the Tx UE2 signal reaching the Rx UE is -60 dBmW, even though the Tx UE1 and Tx UE2 transmit signals are orthogonal in frequency due to in-band leakage. As a result, the signal of Tx UE1 is affected by the strong in-band leakage from Tx UE2, which causes the signal of Tx UE1 to be incorrectly received.

D2D transmission will be affected by in-band leakage interference, and the "far-and-far" effect will cause the impact of in-band leakage interference to be more serious. In-band leakage interference refers to the leakage of signal power to adjacent frequency bands due to non-ideal factors such as Error Vector Magnitude (EVM) and power amplifier nonlinearity.

Step 602: The terminal sends control information to the receiving end, and sends a signal to the receiving end according to the time unit indicated by the determined time domain mode on the determined subband.

The control information sent by the terminal is used by the receiving end to determine the time-frequency resource of the received signal, and when the terminal sends the signal, the terminal sends a signal to the receiving end according to the sub-band and the time domain mode determined in step 601.

Preferably, the control information is used at least to indicate the identity of the determined sub-band.

The terminal may send control information while transmitting a signal to the receiving end, and the control information may be carried in a signal sent to the receiving end.

The terminal can also send control information before sending a signal to the receiving end. And, the control information may be sent by using a resource different from the determined time-frequency resource.

Preferably, if the determined time zone mode set associated with the subband includes more than one time domain mode, the control information is further used to indicate time domain mode indication information of the determined time domain mode, where the time domain mode indication information is used. Uniquely determines a time domain mode.

It should be understood by those skilled in the art that the scope of protection of the present invention is not limited thereto, and other parameters capable of uniquely determining the time domain mode may also be used as time domain mode indication information, and protection in the present invention. Within the scope.

In a specific implementation, the terminal may carry the time domain mode indication information in the control information sent to the receiving end, or determine the resource location of the control channel occupied by the transmission control information, and the receiving end determines that the control information is occupied when receiving the control information. The resource location of the control information determines the time domain mode indication information according to the preset time domain mode indication correspondence relationship between the information and the resource location of the control channel, and then determines the time domain mode according to the time domain mode indication information.

Information about the instructions.

In the embodiment of the present invention, the time unit corresponding to each time domain mode may be included in a fixed length time domain resource, or included in a variable time length time domain resource.

In a preferred embodiment, each time unit included in the time domain mode in the set of time domain modes associated with the subband is determined by a pseudo random sequence, and the pseudo random sequence is mapped by the initial value of the pseudo random sequence according to a preset mapping relationship. After getting it.

Specifically, the pseudo-random sequence may be determined by an initial value of the pseudo-random sequence, and the initial value of the pseudo-random sequence is determined according to the identifier of the sub-band, the identifier of the terminal, the identifier of the receiving end, and the time domain mode in the corresponding index value in the belonging time domain mode set. Any one or any combination is determined.

Based on the same inventive concept, in the second embodiment, as shown in FIG. 7, the detailed method for performing signal reception by the terminal as the receiving end is as follows: Step 701: The terminal determines the sub-band and the time domain mode according to the control information sent by the transmitting end, and determines The time domain mode belongs to a set of time domain modes associated with the determined subband, and each time domain mode corresponds to a set of time units for signal transmission by the terminal.

Each time domain mode corresponds to a different combination of time units, that is, each time domain mode corresponds to a set of different time units.

In a first implementation, if the determined time zone mode set associated with the subband includes only one time domain mode, the control information is used to indicate at least the identifier of the subband, and the terminal determines the identifier of the subband and the subband according to the control information. The time domain mode is determined based on the identity of the subband.

The time domain mode is determined according to the identifier of the subband, and the following two specific implementation manners are available: in the first implementation manner, the terminal according to the preset subband identifier and the time domain mode The mapping relationship acquires the time domain mode corresponding to the subband.

For example, the time domain mode of subband 0 mapping is {0, 1, 2, 3}, that is, data transmission is performed on subframes 0, 1, 2, and 3. The time domain mode of subband 1 mapping is {4, 5,6,7}, that is, data transmission on subframes 4, 5, 6, and 7.

In the second implementation manner, the terminal acquires an initial value of the pseudo-random sequence corresponding to the identifier of the determined sub-band according to the mapping relationship between the identifier of the preset sub-band and the initial value of the pseudo-random sequence, and according to the determined initial value of the pseudo-random sequence And a mapping relationship between the preset pseudo-random sequence initial value and the pseudo-random sequence, determining a pseudo-random sequence, and determining each time unit included in the time domain mode according to the pseudo-random sequence.

For example, the initial value of the pseudo-random sequence of the sub-band mapping identified as i is c _{init, 0} = i .

In a second implementation, if the determined time zone mode set associated with the subband includes more than one time domain mode, the control information is used to at least indicate the identifier of the subband and the time domain mode indication information, where the time domain mode indicates information. The only one time domain mode is determined, the identifier of the subband and the subband are determined according to the control information, and the time domain mode is determined according to the control information.

The determining the time domain mode according to the identifier of the subband indicated by the control information and the time domain mode indication information may have at least three specific implementations. In the first implementation manner, if the time domain mode indication information is the time domain mode Corresponding index value in the time domain mode set, according to the preset time domain mode indicating the correspondence between the information and the time domain mode, from the time domain mode set associated with the subband determined by the identifier of the subband notified by the sender, Obtaining a time domain mode corresponding to the time domain mode indication information notified by the sender as a time domain mode of the received signal.

For example, the set of time domain patterns associated with subband 0 includes two time domain patterns {0, 1, 2, 3} And {4,5,6,7}, whose index values are 0 and 1, respectively. If the time domain mode indicates that the information value is 0, the terminal determines that the time domain mode is {0, 1, 2, 3}, if If the field indication information has a value of 1, the medium terminal determines that the time domain mode is {4, 5, 6, 7}.

In the second implementation manner, if the time domain mode indication information is a pseudo-random sequence initial value parameter, according to a mapping relationship between a preset pseudo-random sequence initial value and a pseudo-random sequence initial value parameter and an identifier of the sub-band, The domain mode indicates an initial value of the pseudo-random sequence corresponding to the information, and determines a pseudo-random sequence according to the determined initial value of the pseudo-random sequence and a mapping relationship between the initial value of the pseudo-random sequence and the pseudo-random sequence, and determines the pseudo-random sequence according to the pseudo-random sequence Each time unit included in the time domain mode.

Specifically, the pseudo-random sequence initial value corresponding to the time domain mode indication information and the identifier information of the subband is determined.

In the third implementation manner, if the time domain mode indication information is a pseudo-random sequence initial value parameter, determining a time domain mode indication information corresponding according to a mapping relationship between a preset pseudo-random sequence initial value and a pseudo-random sequence initial value parameter The initial value of the pseudo-random sequence is determined according to the initial value of the determined pseudo-random sequence and the mapping relationship between the initial value of the pseudo-random sequence and the pseudo-random sequence, and the pseudo-random sequence is determined according to the pseudo-random sequence. Each time unit.

For example, the time domain mode indicates that the information takes the value m , and the initial value of the pseudo-random sequence of the sub-band i is c _init = 2 ¹⁰ . i + m .

In a specific implementation, the mapping relationship between the preset pseudo-random sequence initial value and the pseudo-random sequence initial value parameter and the identifier of the sub-band may further include the identifier information of the terminal itself or the identifier information N _ID of the terminal as the transmitting end.

For example, if the time domain mode indicates that the information is m , and the identity information of the terminal itself is N _ID , the initial value of the pseudo-random sequence of the sub-band i is c _init = 2 ¹⁶ . N _ID +2 ¹⁰ . i + m

In the above implementation, the pseudo-random sequence initial value parameter includes, but is not limited to, an initial value of the pseudo-random sequence, a parameter forming an initial value of the pseudo-random sequence, and an index value corresponding to the initial value of the pseudo-random sequence in the initial set of the pseudo-random sequence. One or any combination. It should be understood by those skilled in the art that the scope of protection of the present invention is not limited thereto, and other parameters capable of determining the initial value of the pseudo random sequence may also be used as pseudo-random sequence initial value parameters, and in the present invention. Within the scope of protection.

Step 702: The terminal receives the signal on the determined subband according to the time unit indicated by the determined time domain mode.

The terminal as the receiving end performs signal reception only on a time unit (such as a subframe) indicated by the determined time domain mode.

In the first and second embodiments, the time domain mode set associated with each subband has the following two specific implementation manners: In the first implementation manner, the time unit corresponding to each time domain mode is included in the fixed length time domain. Within the resource, that is, for a fixed length of time, the length of time contains a set number of time units (such as a subframe), and each time domain mode describes the data transmission within the length of time.

The number of time domain modes included in the time domain mode set associated with different subbands may be the same or different. Moreover, the number of time domain patterns included in the time domain mode set associated with each subband may be one or more.

For example, as shown in FIG. 8, each time domain mode covers 8 subframes, that is, the time domain mode is used to describe data transmission on 8 subframes. Assume the time domain associated with each subband The pattern set includes two modes, mode 0 and mode 1. Mode 0 associated with subband 0 is transmitted on subframes 0, 2, 4, and 6. Mode 1 associated with subband 0 is transmitted on subframes 1, 3, 5, and 7; subband 1 is associated. Mode 0 is transmitted on subframes 0, 1, 4, 5, mode 1 associated with subband 1 is transmitted on subframes 2, 3, 6, and 7; mode 0 associated with subband 2 is in subframe Transmission is performed on blocks 0, 3, 4, and 7, and mode 1 associated with subband 2 is transmitted on subframes 1, 2, 5, and 6; mode 0 associated with subband 3 is in subframe 0, 1, 2 Mode 3 is transmitted, and mode 1 associated with subband 3 is transmitted on subframes 4, 5, 6, and 7.

In the second implementation manner, the time unit corresponding to each time domain mode is included in the time domain resource of variable time length.

Preferably, each time unit included in the time domain mode in the set of time domain modes associated with the subband is determined by a pseudo random sequence, and the pseudo random sequence is obtained by mapping the initial value of the pseudo random sequence according to a preset mapping relationship.

The initial value of the pseudo-random sequence is determined according to any one or any combination of the identifier of the sub-band, the identifier of the sender, the identifier of the receiver, and the time domain mode in the corresponding index value in the set of the time-domain modes.

Specifically, the pseudo-random sequence determines that each time unit included in the time domain mode has multiple implementation manners, as follows:

To achieve one, the initial value of the pseudo-random sequence of the sub-band with the sub-band identifier (such as number) i is c _{init, 0} = 2. i and c _{init, 1} = 2. i +1, the initial values of the two random sequences can be generated according to a preset mapping relationship to generate two pseudo-random sequences. Each bit of the pseudo-random sequence corresponds to one subframe. If the bit has a value of 1, the corresponding subframe can be transmitted. If the bit is 0, the corresponding subframe is not. Data transfer. Since the length of the pseudo-random sequence can be infinitely extended, it can implement a time domain mode of variable time length. The subband with the subband number i corresponds to two initial values of the pseudo random sequence, and the time domain mode set associated with the subband includes two time domain modes. If there is only one element in the set of time domain patterns associated with a subband, then the pseudorandom sequence of the subband needs only one value, such as c _init = i or c _init = 2 ¹⁰ . N _ID + i .

Implementing two, the initial value of the pseudo-random sequence of the sub-band with the sub-band identifier (such as number) being i is c _init = i , and the pseudo-random sequence may be generated according to the preset mapping relationship, and a pseudo-random sequence may be generated. Each bit of the pseudo-random sequence is inverted (eg '0' is inverted by '1', '1' is inverted by '0'), another pseudo-random sequence is obtained, and two pseudo-random sequences are determined by the two pseudo-random sequences. Time domain mode.

In implementation one and implementation two, the initial value of the pseudo-random sequence may be other functions of the sub-band identifier (number), such as c _init = 2 ¹⁰ . i .

The initial value of the pseudo-random sequence of the sub-band whose sub-band identifier (such as number) is i is c _{init, 0} = 2 ¹⁰ . N _ID +2. i and c _{init, 1} = 2 ¹⁰ . N _ID +2. i +1, where N _ID is the identifier of the terminal, and the terminal may be a data sending end or a data receiving end. The method of generating a pseudo-random sequence by mapping two initial values according to a preset mapping relationship, and then determining the time domain mode is the same as implementing one and implementing two.

In this implementation, the subband with the subband identifier (number) i corresponds to two pseudo random sequence initial values, so that the time domain mode set associated with the subband includes two time domain modes.

Implementation 4: If M time domain modes are to be included in a time zone mode set associated with a subband, the initial value of the pseudo random sequence of the subband with the subband identifier (eg, number) i can be expressed as: c _init,m =2 ¹⁰ . N _ID +2 ⁵ . i + m , m =0 , 1 , 2 ..., M -1, where N _ID is the identifier of the terminal, and m represents the index value corresponding to the time domain mode in the set of the time domain mode, and M pseudo- The initial value of the random sequence, and then the M pseudo-random sequences can be generated according to the preset mapping relationship according to the initial values of the M pseudo-random sequences, and M time-domain modes are obtained.

The initial value of the pseudo-random sequence of the sub-band with the sub-band number i is c _init = 2 ¹⁰ . N _ID + i , where N _ID represents the identifier of the terminal, and may be an identifier of the data sending end or an identifier of the data receiving end. After the initial value of the pseudo-random sequence is mapped according to a preset mapping relationship, a pseudo-random sequence can be generated, and each bit of the pseudo-random sequence is inverted ('0' is inverted by '1', and '1' is inverted. Is '0'), another pseudo-random sequence is obtained, from which two time-domain modes are determined.

Implementation 6, if M time domain mode is to be included in a subband association time domain mode set, the initial value of the pseudo random sequence of the subband with the subband identifier (such as number) i can be expressed as: c _init,m =2 ¹⁰ . N _ID + k _m , m =0,1,2..., M -1, where N _ID is the identifier of the terminal, and m represents the index value corresponding to the time domain mode in the corresponding time domain mode set, and M can be obtained. An initial value of a pseudo-random sequence, k _m is an integer and k _m belongs to a set Ki composed of M integers, and further, according to a preset mapping relationship, the initial values of the M pseudo-random sequences are mapped according to a preset mapping relationship, and M pseudo-random sequences are generated. Get M time domain modes.

In the foregoing implementations, the initial value of the pseudo-random sequence may be determined according to the preset mapping relationship. The pseudo-random sequence may be in multiple manners. The implementation of the present invention is not limited. The initial values of various pseudo-random sequences existing in the prior art are based on presets. The manner in which the mapping relationship map determines the pseudo-random sequence is applicable to the present invention.

For example, the mapping generates an M sequence. Assuming that the register length of the M sequence is L, the relationship between the initial state of each register and the initial value of the pseudo-random sequence is: Where x ( n ) is the initial state of the nth register, with a value of 0 or 1, and c _init is the initial value of the pseudo-random sequence.

As another example, a Gold sequence is generated from a pseudo-random sequence initial value map.
