Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a device for configuring a duration.
Background
In Vehicle-to-electrical (V2X) communication, a receiving User Equipment (UE) may need to receive signals of multiple different sending UEs, and since the sending UEs are different in location, the change of signal strength may be large when the sending UEs arrive at the receiving UEs, so that power adjustment needs to be performed on the received signals. The receiver of the UE includes an Automatic Gain Control (AGC) adjustment module and an Analog-to-Digital Converter (ADC) module, where the AGC is used to adjust the power of a signal entering the ADC, so as to ensure that the power of the ADC changes within a certain range, thereby helping to reduce quantization error during ADC sampling. In the implementation, the procedure of AGC measurement needs to be introduced, and the AGC is adjusted for a period of time, so that the AGC converges to a stable state. The prior art fixedly uses the first Orthogonal Frequency Division Multiplexing (OFDM) symbol of a subframe or a slot to complete AGC measurement adjustment. In addition, considering the influence of the UE's own receiving/transmitting switching, since the UE may be in a receiving state in a previous subframe or timeslot and may be in a transmitting state in a subsequent subframe or timeslot, in order to complete a switching action for a reserved time for switching between receiving/transmitting, a Guard Period (GP) needs to be introduced between subframes or timeslots, and the GP in the prior art also occupies a symbol. However, flexible subcarrier spacing configuration is introduced in the new 5G Radio Access technology (NR, abbreviated as NR), which causes the length of symbols in a subframe to change and is no longer a fixed value. The duration required by AGC and/or GP is generally a fixed value, and configuring AGC or GP in the prior art to fixedly occupy a symbol results in a shortened symbol length under a larger subcarrier interval, resulting in insufficient time to complete AGC and/or GP, which increases the bit error rate of a receiver and decreases the utilization rate of system resources.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Fig. 1 shows a system architecture applicable to the embodiment of the present application, where the system architecture includes a sending terminal 101, a receiving terminal 102, and a base station 103.
The sending terminal 101 and the receiving terminal 102 are electronic devices with network communication capability, and the electronic devices may be smart phones, tablet computers, portable personal computers, smart cars, smart homes, and the like. The base station 103 is a device for accessing the transmitting terminal 101 and the receiving terminal 102 to the wireless network, and includes but is not limited to: evolved node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), home base station (e.g., home evolved node B (HNB), Base Band Unit (BBU), base station (g nodeB, gbb), transmission point (TRP), Transmission Point (TP), mobile switching center (msc), etc. The transmission terminal 101 and the reception terminal 102 may communicate with each other through the base station 103, or may directly perform Sidelink communication.
Based on the system architecture diagram shown in fig. 1, an embodiment of the present application provides a flow of a duration configuration method, where the flow of the method may be executed by a duration configuration device, as shown in fig. 2, and includes the following steps:
step S201, obtains subcarrier spacing information.
Alternatively, the subcarrier spacing information may be setting information of subcarrier spacing, such as subcarrier spacing of 7.5kHz, 15kHz, 30kHz, 60kHz, or the like. The subcarrier spacing information may also be information associated with subcarrier spacing.
Step S202, determining the duration information occupied by the automatic gain control and/or the duration information occupied by the guard interval according to the subcarrier interval information.
The duration information includes, but is not limited to, OFDM symbol number information, Ts information.
Specifically, the present application provides at least the following two embodiments for determining duration information occupied by automatic gain control and/or duration information occupied by guard interval according to subcarrier interval information:
in a possible implementation manner, a comparison table is preset, and the comparison table stores a correspondence relationship between subcarrier interval information and duration information occupied by automatic gain control and/or duration information occupied by guard interval in advance. And then, according to the carrier interval information, inquiring the comparison table to determine the duration information occupied by the automatic gain control and/or the duration information occupied by the guard interval.
For example, the set duration information is OFDM symbol number information, and the preset look-up table is shown in table 1:
TABLE 1
| Serial number | Sidelink subcarrier spacing | Number of symbols occupied by AGC | Number of symbols occupied by |
| 1 | |
1 | 1 |
| 2 | |
2 | 2 |
| 3 | |
4 | 4 |
When the obtained sildelink subcarrier interval is 30KHz, the look-up table shown in table 1 indicates that the number of symbols occupied by AGC is 2, the number of symbols occupied by GP is 2, and the corresponding obtained slot structure is shown in fig. 3, where the 0 th symbol and the 1 st symbol in the slot are occupied by AGC, the 12 th symbol and the 13 th symbol in the slot are occupied by GP, and DATA (DATA) and Demodulation pilot Signal (DMRS for short) occupy other symbols in the slot. Because the comparison table is preset, the number of symbols occupied by the automatic gain control and/or the number of symbols occupied by the guard interval can be obtained by directly inquiring the comparison table, calculation according to the subcarrier interval is not needed, and the method is convenient and quick.
In another possible embodiment, as shown in fig. 4, the method comprises the following steps:
Alternatively, the duration unit information may use a single OFDM symbol as the duration unit, or may use Ts as the duration unit. When a single OFDM symbol is taken as a duration unit, the subcarrier spacing is inversely proportional to the OFDM symbol length, as shown in the following formula (1):
After obtaining the subcarrier spacing, the symbol length of each OFDM symbol may be calculated according to equation (1).
Step S402, determining the time length information occupied by the automatic gain control according to the time length required by the automatic gain control and the time length unit information.
Step S403, determining the duration information occupied by the guard interval according to the duration required by the guard interval and the duration unit information.
The duration required for automatic gain control and the duration required for the guard interval are fixed and generally related to device performance. When a single OFDM symbol is used as a time length unit, after the OFDM symbol length is calculated by adopting a formula (1), the number of the OFDM symbols required to be occupied by the automatic gain control can be determined according to the time length required by the automatic gain control, and the number of the OFDM symbols required to be occupied by the guard interval can be determined according to the time length required by the guard interval.
Alternatively, in step S402, the duration configuration device may directly configure the calculated number of OFDM symbols that need to be occupied by the agc to the number of OFDM symbols actually occupied by the agc in the receiving terminal. Exemplarily, the subcarrier interval is set to be 30kHz, the number of OFDM symbols required to be occupied by the agc is 2 obtained through calculation, and the agc in the receiving terminal is configured to occupy 2 OFDM symbols.
The duration configuration device may also configure the number of OFDM symbols actually occupied by the agc in the receiving terminal in combination with the calculated number of OFDM symbols required to be occupied by the agc and the actual communication scenario. Exemplarily, the subcarrier interval is set to be 30kHz, the number of OFDM symbols required to be occupied by the agc is 2 obtained through calculation, and 1 OFDM symbol can be occupied by the agc in the receiving terminal configured in combination with an actual communication scenario.
Similarly, in step S403, the duration configuration device may directly configure the calculated number of OFDM symbols that need to be occupied by the guard interval as the number of OFDM symbols actually occupied by the guard interval in the receiving terminal. The number of OFDM symbols actually occupied by the guard interval in the receiving terminal may also be configured in combination with the calculated number of OFDM symbols that need to be occupied by the guard interval and the actual communication scenario. Because the number of symbols actually occupied by the automatic gain control in the receiving terminal and/or the number of symbols actually occupied by the guard interval are determined according to the symbol length and the actual communication scene, the configuration mode is more flexible, and the method is suitable for various scenes.
Optionally, in this embodiment of the present application, the duration configuration device may be at least a configuration device and a receiving terminal, where the configuration device is a third-party device other than the receiving terminal. When the duration configuration device is a configuration device, after determining duration information occupied by the automatic gain control and/or duration information occupied by the guard interval according to the subcarrier interval information, the configuration device may send the duration information occupied by the automatic gain control and/or the duration information occupied by the guard interval to the receiving terminal to implement the duration configuration of the receiving terminal, or may implement the duration configuration of the receiving terminal by using an implicit indication manner. When the time length configuration device is a receiving terminal, the receiving terminal directly configures the time length of the receiving terminal after determining the time length information occupied by the automatic gain control and/or the time length information occupied by the guard interval according to the subcarrier interval information. Because the number of symbols occupied by the automatic gain control and/or the number of symbols occupied by the guard interval are configured according to the setting condition of the subcarrier interval, rather than configuring the automatic gain control and/or the guard interval to fixedly occupy one symbol, enough time can be ensured to finish the automatic gain control and/or the guard interval when the subcarrier interval changes, the waste of time-frequency resources is avoided, and the error rate performance and the resource utilization performance of data transmission are improved.
The following specifically describes two cases, namely, the duration configuration device is a configuration device and the duration configuration device is a receiving terminal.
Fig. 5 exemplarily shows a flow of a duration configuration method provided by an embodiment of the present application, where the flow of the method may be executed by a configuration device, and includes the following steps:
step S501, the configuration device obtains subcarrier spacing information.
Step S502, determining the duration information occupied by the automatic gain control and/or the duration information occupied by the guard interval according to the subcarrier interval information.
Step S503, sending the duration information occupied by the agc and/or the duration information occupied by the guard interval to the receiving terminal.
Optionally, the duration information includes, but is not limited to, OFDM symbol number information, Ts information.
In a possible implementation manner, the configuration device is a base station, and the base station sends the duration information occupied by the automatic gain control and/or the duration information occupied by the guard interval to the receiving terminal through an air interface signaling. In a specific implementation, the base station may notify the receiving terminal of the number of symbols occupied by the agc and/or the guard interval used for subsequent data transmission through a broadcast message. The base station may also signal, through dynamic Downlink Control Information (DCI) in a Physical Downlink Control Channel (PDCCH for short), the number of symbols occupied by the automatic gain Control and/or the guard interval used for subsequent data transmission by the terminal. The base station may also notify the receiving terminal of the number of symbols occupied by the automatic gain Control and/or the guard interval used for subsequent data transmission through a Radio Resource Control (RRC) signaling. For example, as shown in fig. 6, before the terminal 1 and the terminal 2 perform the Sidelink data communication, the base station sends an air interface signaling to notify the terminal 1 and the terminal 2 of the number of symbols occupied by the automatic gain control and/or the guard interval used for the subsequent data transmission.
In another possible implementation, the configuration device is a sending terminal, and the sending terminal sends the duration information occupied by the automatic gain control and/or the duration information occupied by the guard interval to the receiving terminal through a Sidelink signaling. In a specific implementation, the sending terminal notifies the receiving terminal of the number of symbols occupied by the automatic gain control and/or the guard interval used for subsequent data transmission through the Sidelink broadcast message. The sending terminal may also notify the receiving terminal of the number of symbols occupied by the automatic gain control and/or the guard interval used for subsequent data transmission through the Sidelink dynamic signaling. The sending terminal may further notify the receiving terminal of the number of symbols occupied by the automatic gain control and/or the guard interval used for subsequent data transmission through a Sidelink semi-static signaling, and the sending terminal may further notify the receiving terminal of the number of symbols occupied by the automatic gain control and/or the guard interval used for subsequent data transmission through a near field Communication Port 5(Proximity Communication Port 5, abbreviated as PC 5). Exemplarily, as shown in fig. 7, the terminal 1 is a sending terminal, the terminal 2 is a receiving terminal, and before the terminal 1 and the terminal 2 perform the Sidelink data communication, the terminal 1 sends a Sidelink signaling to notify the terminal 2 of the number of symbols occupied by the automatic gain control and/or the guard interval for subsequent data transmission. The configuration equipment flexibly configures the number of the symbols occupied by the automatic gain control and/or the guard interval of the receiving terminal according to the subcarrier interval information, can perform dynamic or semi-static adjustment, and is simple and direct, but not fix the number of the symbols occupied by the automatic gain control and/or the guard interval into one symbol, thereby ensuring that enough time is available for completing the automatic gain control and/or the guard interval, and improving the error rate performance and the resource utilization performance of the Sidelink data transmission.
Fig. 8 illustrates a flow of a duration configuration method provided by an embodiment of the present application, where the flow of the method may be executed by a receiving terminal, and includes the following steps:

Step S802, determining the duration information occupied by the automatic gain control and/or the duration information occupied by the guard interval according to the subcarrier interval information.
Optionally, the duration information includes, but is not limited to, OFDM symbol number information, Ts information.
Optionally, the receiving terminal queries a comparison table according to the subcarrier spacing information to determine duration information occupied by the automatic gain control and/or duration information occupied by the guard interval, and the comparison table pre-stores a corresponding relationship between the subcarrier spacing information and the duration information occupied by the automatic gain control and/or the duration information occupied by the guard interval.
In a specific implementation, after the receiving terminal is powered on, the receiving terminal may automatically read a preset comparison table stored in the receiving terminal, for example, table 1, and when the subcarrier interval information is obtained, determine the number of symbols occupied by the automatic gain control and/or the guard interval according to the corresponding relationship in the table, for example, when the subcarrier interval is obtained as 15kHz, determine that the automatic gain control occupies one symbol and the guard interval occupies one symbol according to the corresponding relationship in table 1. The receiving terminal may also read a preset comparison table issued by the base station from the base station side after the power is turned on, and determine the number of symbols occupied by the automatic gain control and/or the guard interval according to the corresponding relationship in the table when the subcarrier interval information is acquired. After the receiving terminal acquires the subcarrier interval information, the number of symbols occupied by the automatic gain control and/or the guard interval is determined according to the preset comparison table and time duration configuration is carried out, and the time duration configuration is carried out on the receiving terminal without the need of configuring equipment for sending the number of symbols occupied by the automatic gain control and/or the guard interval through air interface signaling or Sidelink signaling, so that the air interface signaling or the Sidelink signaling is not required to be occupied, and the expenditure is reduced.
