Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to an uplink signal transmission method and apparatus for a communication system.
Background
Authorized frequency points of a 230MHz multi-sub-band communication system are discretely distributed on the frequency band of 223.525 MHz-231.65 MHz, each bandwidth is 25KHz, and the system is called as a physical sub-band. Wherein, part of the frequency points are divided separately as the residence zone, the rest frequency points are used as the working zone, and the residence zone sub-band is further divided into a synchronous sub-band and a service sub-band. The base station schedules the terminal to operate on different subbands.
The system designs 1 synchronous frame on each service sub-band and every 40 wireless frames, the synchronous frame sends synchronous signals in the downlink for terminal synchronization, and the uplink resource position of the synchronous frame is completely silent and does not send signals. The base station may make channel quality measurements based on the synchronization frames. The system supports a spectrum sensing technology based on base station measurement and terminal feedback. The base station may dynamically change the location and number of active subbands for the terminal to achieve channel quality for one or a group of subbands. The base station combines the self full bandwidth measurement and the report information of the terminal to schedule the terminal to the sub-band with better channel condition, thereby effectively avoiding the sub-band with serious interference.
The UpPTS position (UpPTS: Uplink Pilot Time Slot) on each traffic sub-band is allocated as the position of SR Request (Scheduling Request). In every 8 radio frames, a cell may be assigned to the UpPts location in one radio frame for SR transmission. The radio frame at which each cell transmits the SR can be determined by the cell ID number modulo 8 and the frame number modulo 8. Fig. 1 is a schematic diagram of an SR channel structure of the current system. In fig. 1, the SR scheduling period is 40 radio frames (
Duration 1s) as an example, the scheduling request is
In which n is a number of radio frames, in whichfIs the frame number. And the communication terminal calculates a corresponding uplink scheduling request time domain index (index is 0-7) according to the ID number of the cell where the communication terminal is positioned modulo 8, and selects one SR from the uplink scheduling request time domain corresponding to the index to perform uplink scheduling request attempt. Users in the same cell
And sending once in a period.
In the uplink signal muting method of the current system, when a synchronization frame is encountered, the uplink resource position is completely muted, which results in that the SR resource of the Cell with the Cell ID number modulo 8 being zero is 20% less than the SR resource of other cells, as shown in fig. 1, the ID number modulo 8 of the Cell8 is zero, the UE of the Cell8 can only send SR requests in 4 frames (frame 8, frame 16, frame 24, and frame 32) and cannot send SR requests in the frame 40, because the frame 40 is a synchronization frame, the uplink resource position of the frame 40 is completely muted and cannot send SR requests, and the UE of other cells can send SR requests in 5 frames, which results in that the SR resource of the Cell8 is 20% less than the SR resource of other cells. Therefore, the cell ID with the cell ID number modulo 8 being zero should be selected as little as possible during networking, which increases the complexity of networking design.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 2, a schematic flow chart of an uplink signal transmission method of a communication system according to an embodiment of the present invention includes:
specifically, the execution subject of the embodiment of the present invention is a terminal.
In the prior art, a 230MHz multi-subband communication system designs 1 synchronization frame every 40 frames on each service subband. The synchronization frame refers to a wireless frame for sending a synchronization signal in a downlink and silencing the position of uplink resources. The synchronization signal is used to ensure that the UE performs normal carrier synchronization and time synchronization on the service subband. The uplink resource position silence is used for base station measurement, and the base station can perform channel quality measurement based on the synchronization frame.
Since the position of the uplink pilot time slot UpPTS in the radio frame structure corresponding to each service sub-band is allocated as the position for sending an uplink scheduling request, i.e., an SR request, when the terminal occupies the uplink pilot time slot UpPTS position of the current radio frame to send the SR request, it should be noted that the frame number mod 8 of the current frame is equal to the cell ID mod 8 of the cell in which the terminal is located. If the current radio frame is a synchronization frame, in the prior art, the terminal cannot send an SR request because the uplink resource location of the synchronization frame is completely silent. In order to solve the problem, the embodiment of the present invention first determines whether a current radio frame of the terminal sending the SR request is a synchronization frame, and specifically determines whether a frame number mod 40 is equal to zero.
Specifically, if the terminal knows that the current radio frame is a synchronization frame, the terminal sends an uplink scheduling request by using an uplink pilot time slot (UpPTS) of the current radio frame based on preset configuration of uplink signal silence.
The preset configuration of the uplink signal silence specifically includes: the uplink resource location is partially muted in the radio frame structure.
The radio frame structure of the 230MHz multi-subband communication system comprises 5 subframes, wherein the second subframe is a special subframe and consists of a downlink pilot time slot DwPTS, a guard interval GP and an uplink pilot time slot UpPTS, the first subframe and the downlink pilot time slot DwPT are used for downlink transmission, and the uplink pilot time slot UpPTS, the third subframe, the fourth subframe and the fifth subframe are used for uplink transmission. It can be understood that the uplink resource location of the radio frame structure includes an uplink pilot timeslot UpPTS, a third subframe, a fourth subframe, and a fifth subframe. And the third subframe, the fourth subframe and the fifth subframe are all called uplink subframes.
The uplink resource position of the wireless frame structure comprises an uplink pilot time slot (UpPTS) and three uplink subframes, and the uplink resource position in the wireless frame structure is configured to be partially silent, so that the position of the uplink pilot time slot (UpPTS) in the current wireless frame is not silent, and the terminal can normally send an SR request by using the uplink pilot time slot (UpPTS).
It should be noted that when configuring the partial silence of the uplink resource location in the radio frame structure, it needs to consider not to affect the signal demodulation, and also not to occupy the symbol corresponding to the uplink reference signal.
The uplink signal transmission method of the communication system provided by the embodiment of the invention is based on the preset configuration of the silence of part of the uplink signals, so that the resource positions occupied by the SR requests in the synchronous frame are not silent, all cells can have the same SR resource quantity, and the complexity of the networking design can be simplified.
Based on the content of the foregoing embodiment, the muting of the uplink resource position in the radio frame structure specifically includes:
any one uplink subframe in the three uplink subframes of the wireless frame structure is a silent frame; or,
any two uplink subframes in the three uplink subframes of the wireless frame structure are silent frames; or,
three uplink subframes of the wireless frame structure are silent frames;
the silence frame is specifically a radio frame in which part of or all of the symbols are in a silence state.
In the embodiment of the invention, the 3bit information can be used for indicating the partial silence of the uplink resource position. Specifically, there are seven following ways to implement the partial muting of the uplink resource position:
any one of the three uplink subframes of the wireless frame structure is a silent frame, namely a third subframe, a fourth subframe or a fifth subframe is a silent frame; or,
any two uplink subframes in the three uplink subframes of the wireless frame structure are silent frames, namely a third subframe and a fourth subframe are silent frames, and the third subframe and a fifth subframe are silent frames, or the fourth subframe and the fifth subframe are silent frames;
three uplink subframes of the radio frame structure are all silent frames, namely a third subframe, a fourth subframe and a fifth subframe are all silent frames.
The silence frame refers to a radio frame in which a symbol in a silence state exists, and may be a part of symbols of the radio frame in the silence state or all symbols of the radio frame in the silence state.
In another embodiment of the present invention, based on the above embodiment, the uplink subframe is a silence frame, which specifically includes:
and the last N symbols of the uplink subframe are in a silent state, wherein the value of N is 1, 2 or 3.
It can be understood that if the last N symbols of a certain uplink subframe are in the silence state, the uplink subframe is a silence frame.
Wherein N is 1, 2 or 3.
Based on the content of the foregoing embodiment, the uplink signal transmission method of the communication system further includes:
when uplink control channel PUCCH transmission is carried out, symbols in a silent state are determined based on the preset configuration of uplink signal silence, and the symbols in the silent state are subjected to punching processing; and/or the presence of a gas in the gas,
and when the uplink shared channel PUSCH transmission is carried out, determining the symbol in the silent state based on the preset configuration of the uplink signal silence, and carrying out punching or rate matching processing on the symbol in the silent state.
Specifically, when a synchronization frame is encountered by a PUCCH (Physical Uplink Control CHannel) and a PUSCH (Physical Uplink Shared CHannel), the transmission processing when the Uplink resource position is completely silent is as follows: the PUCCH encounters a synchronous frame, and if resources exist in the current scheduling period, the PUCCH delays to transmit; if no resource exists, the PUCCH is not sent, and the base station defaults that the HARQ feedback of the PDSCH in the current period is ACK; when the PUSCH encounters a synchronization frame, puncturing or rate matching needs to be adopted according to the situation. Meanwhile, whether the PUCCH is delayed or not needs to be considered. The uplink resource position complete silence can cause PUCCH and PUSCH to encounter synchronous frames, and the complexity of sending and processing is high when the uplink is completely silent.
In the embodiment of the invention, when a terminal transmits an uplink control channel PUCCH and/or an uplink shared channel PUSCH, if a synchronous frame is encountered, a symbol in a silent state is firstly determined based on the preset configuration of a system for uplink signal silence, and then the symbol in the silent state is processed.
Specifically, when uplink control channel PUCCH transmission is performed, if the terminal knows that the current radio frame is a synchronization frame, the terminal determines a symbol in a silent state based on the preset configuration of uplink signal silence, and performs puncturing on the symbol in the silent state, so that the PUCCH ignores the symbol in the silent state.
When uplink shared channel PUSCH transmission is carried out, if the terminal knows that the current radio frame is a synchronous frame, the symbol in the silent state is determined based on the preset configuration of the uplink signal silence, and the symbol in the silent state is subjected to punching or rate matching processing. Wherein mapping PUSCH data onto symbols in a silent state can be avoided by rate matching.
The uplink signal transmission method of the communication system provided by the embodiment of the invention can effectively reduce the complexity of networking design and can also effectively reduce the complexity of sending and processing physical layer PUCCH and PUSCH channels.
Fig. 3 to 7 correspond to the signal silent transmission cases in various transmission cases, where the last 3 symbols of each subframe in an uplink subframe are in a silent state, fig. 3 is a schematic diagram when the uplink subframe only transmits PUSCH, fig. 4 is a schematic diagram when the uplink subframe only transmits PUSCH, fig. 5 is a schematic diagram when the uplink subframe transmits PUCCH (format 0) and PUSCH, fig. 6 is a schematic diagram when the uplink subframe transmits PUCCH (format 3) and PUSCH, and fig. 7 is a schematic diagram when the uplink subframe transmits PUCCH (format 1 or format 2). As can be seen from the above diagrams, the uplink signal transmission method of the communication system according to the embodiment of the present invention can reduce the complexity of the transmission processing of the PUCCH and the PUSCH channels, and ensure that the transmission performance of the PUCCH and the PUSCH is not negatively affected by the muting of the uplink partial signal.
As shown in fig. 8, a schematic structural diagram of an uplink signal transmission apparatus of a communication system according to an embodiment of the present invention includes: a decision block 801 and a sending block 802, wherein,
a judging module 801, configured to judge whether a current wireless frame is a synchronization frame;
specifically, in the prior art, the 230MHz multi-subband communication system designs 1 synchronization frame every 40 frames on each traffic subband. The synchronization frame refers to a wireless frame for sending a synchronization signal in a downlink and silencing the position of uplink resources. The synchronization signal is used to ensure that the UE performs normal carrier synchronization and time synchronization on the service subband. The uplink resource position silence is used for base station measurement, and the base station can perform channel quality measurement based on the synchronization frame.
Since the position of the uplink pilot time slot UpPTS in the radio frame structure corresponding to each service sub-band is allocated as the position for sending an uplink scheduling request, i.e., an SR request, when the terminal occupies the uplink pilot time slot UpPTS position of the current radio frame to send the SR request, it should be noted that the frame number mod 8 of the current frame is equal to the cell ID mod 8 of the cell in which the terminal is located. If the current radio frame is a synchronization frame, in the prior art, the terminal cannot send an SR request because the uplink resource location of the synchronization frame is completely silent. In order to solve the problem, the determining module 801 determines whether the current radio frame transmitting the SR request is a synchronization frame, and the determining module 801 determines whether the current radio frame is a synchronization frame according to whether the frame number modulo 40 is equal to zero.
A sending module 802, configured to send an uplink scheduling request by using an uplink pilot timeslot UpPTS of a current radio frame based on a preset configuration of uplink signal silence if it is known that the current radio frame is a synchronization frame;
the preset configuration of the uplink signal silence specifically includes: the uplink resource location is partially muted in the radio frame structure.
Specifically, if the sending module 802 knows that the current radio frame is a sync frame, the uplink scheduling request is sent by using an uplink pilot timeslot UpPTS of the current radio frame based on a preset configuration of uplink signal silence.
The preset configuration of the uplink signal silence specifically includes: the uplink resource location is partially muted in the radio frame structure.
The radio frame structure of the 230MHz multi-subband communication system comprises 5 subframes, wherein the second subframe is a special subframe and consists of a downlink pilot time slot DwPTS, a guard interval GP and an uplink pilot time slot UpPTS, the first subframe and the downlink pilot time slot DwPT are used for downlink transmission, and the uplink pilot time slot UpPTS, the third subframe, the fourth subframe and the fifth subframe are used for uplink transmission. It can be understood that the uplink resource location includes an uplink pilot timeslot UpPTS, a third subframe, a fourth subframe, and a fifth subframe. The third subframe, the fourth subframe and the fifth subframe are referred to as uplink subframes.
The uplink resource position of the wireless frame structure includes an uplink pilot time slot UpPTS and three uplink subframes, and the uplink resource position in the wireless frame structure is configured to be partially silent, so that the position of the uplink pilot time slot UpPTS in the current wireless frame is not silent, and the sending module 802 can normally send an SR request by using the uplink pilot time slot UpPTS.
It should be noted that when configuring the partial silence of the uplink resource location in the radio frame structure, it needs to consider not to affect the signal demodulation, and also not to occupy the symbol corresponding to the uplink reference signal.
The uplink signal transmission device of the communication system provided by the embodiment of the invention is based on the preset configuration of the silence of part of the uplink signals, so that the resource positions occupied by the SR requests in the synchronous frame are not silent, all cells can have the same SR resource quantity, and the complexity of the networking design can be simplified.
Based on the content of the foregoing embodiment, the muting of the uplink resource position in the radio frame structure specifically includes:
any one uplink subframe in the three uplink subframes of the wireless frame structure is a silent frame; or,
any two uplink subframes in the three uplink subframes of the wireless frame structure are silent frames; or,
three uplink subframes of the wireless frame structure are silent frames;
the silence frame is specifically a radio frame in which part of or all of the symbols are in a silence state.
In the embodiment of the invention, the 3bit information can be used for indicating the partial silence of the uplink resource position. Specifically, there are seven following ways to implement the partial muting of the uplink resource position:
any one of the three uplink subframes of the wireless frame structure is a silent frame, namely a third subframe, a fourth subframe or a fifth subframe is a silent frame; or,
any two uplink subframes in the three uplink subframes of the wireless frame structure are silent frames, namely a third subframe and a fourth subframe are silent frames, and the third subframe and a fifth subframe are silent frames, or the fourth subframe and the fifth subframe are silent frames;
three uplink subframes of the radio frame structure are all silent frames, namely a third subframe, a fourth subframe and a fifth subframe are all silent frames.
The silence frame refers to a radio frame in which a symbol in a silence state exists, and may be a part of symbols of the radio frame in the silence state or all symbols of the radio frame in the silence state.
Based on the content of the above embodiment, the uplink subframe is a silence frame, which specifically includes:
and the last N symbols of the uplink subframe are in a silent state, wherein the value of N is 1, 2 or 3.
It can be understood that if the last N symbols of a certain uplink subframe are in the silence state, the uplink subframe is a silence frame. Wherein the value of N is 1, 2 or 3.
Based on the content of the foregoing embodiment, the uplink signal transmission apparatus of the communication system further includes:
the processing module is used for determining a symbol in a silent state based on preset configuration of uplink signal silence when uplink control channel PUCCH transmission is carried out, and carrying out punching processing on the symbol in the silent state; and/or the presence of a gas in the gas,
and the method is used for determining the symbol in the silent state based on the preset configuration of the uplink signal silence when the uplink shared channel PUSCH transmission is carried out, and carrying out punching or rate matching processing on the symbol in the silent state.
Specifically, when a synchronization frame is encountered by a PUCCH (Physical Uplink Control CHannel) and a PUSCH (Physical Uplink Shared CHannel), the transmission processing when the Uplink resource position is completely silent is as follows: the PUCCH encounters a synchronous frame, and if resources exist in the current scheduling period, the PUCCH delays to transmit; if no resource exists, the PUCCH is not sent, and the base station defaults that the HARQ feedback of the PDSCH in the current period is ACK; when the PUSCH encounters a synchronization frame, puncturing or rate matching needs to be adopted according to the situation. Meanwhile, whether the PUCCH is delayed or not needs to be considered. The uplink resource position complete silence can cause PUCCH and PUSCH to encounter synchronous frames, and the complexity of sending and processing is high when the uplink is completely silent.
The embodiment of the invention adds a processing module for determining the symbol in the silent state first and then processing the symbol in the silent state based on the preset configuration of the system for silencing the uplink signal if a synchronization frame is encountered during transmission of an uplink control channel PUCCH and/or an uplink shared channel PUSCH.
Specifically, when uplink control channel PUCCH is transmitted, if the processing module knows that the current radio frame is a synchronization frame, the processing module determines a symbol in a silent state based on the preset configuration of uplink signal silence, and performs puncturing processing on the symbol in the silent state, so that the PUCCH ignores the symbol in the silent state.
When uplink shared channel PUSCH transmission is carried out, if the processing module learns that the current radio frame is a synchronous frame, the symbol in the silent state is determined based on the preset configuration of uplink signal silence, and the symbol in the silent state is subjected to punching or rate matching processing. Wherein mapping PUSCH data onto symbols in a silent state can be avoided by rate matching.
