AI Technical Summary
When the terminal sends data signals to the base station, if a beam signal with poor quality is used, it may cause the base station to parse the data signal incorrectly; waiting for a beam with good quality will increase the delay.
After receiving the beam signal sent by the base station, the terminal judges the beam quality. If a beam of good quality exists, the verification signal and data signal are directly used to send the beam. If it does not exist, the verification signal is sent using the second best beam first and the beam signal continues to be received within a certain period of time. If a beam of good quality is obtained within this time, it is used to send a data signal; otherwise, continue to use the second best beam to send a data signal.
In this way, when there are better beams at the beginning, the sent data signal is of good quality and has no delay; when there are no better beams at the beginning, the verification signal is first used to send the second best beam, if it is short If a good beam is present in time, the transmitted data signal is of good quality and the delay is small; if there is no better beam, the best quality beam is selected to send the data signal under short delay.

Therefore, the regions illustrated in the drawings have schematic properties, and the shapes of the regions shown in the drawings illustrate the specific shapes of the regions of the elements, but are not intended to be limiting.
[0042] First, refer to Figure 1 The embodiment of the present disclosure provides a method for sending a signal, which is used by a terminal to send a data signal to a base station, that is, implemented on devices and chips such as a digital signal processor (DSP), a field programmable gate array (FPGA), and an application specific integrated circuit (ASIC), and the method specifically includes:
[0043] S101. Receive at least one beam signal from a base station, where each beam signal corresponds to a beam.
[0044] A terminal (such as a mobile phone) receives a beam signal (such as an SSB signal) from a base station. The beam signal is a signal carried by a beam that the base station periodically sends in different directions, that is, the beam signal corresponds to the beam one-to-one.
[0045] The base station sends beams carrying beam signals in fixed directions within a time slot. The received beam signal in this step is the beam signal sent by the base station within the same time slot. Due to the influence of environmental factors, the beam attenuation in different directions is different. Therefore, the terminal may only receive one beam signal from the base station, or may receive multiple beam signals of different quality from different directions.
[0046] S102: If the received beam signal includes a first beam signal whose quality satisfies a first quality condition, use the first beam corresponding to the first beam signal to send a verification signal and a data signal to the base station, where the verification signal is used by the base station to verify the identity of the terminal.
[0047] After receiving the beam signal sent by the base station, the terminal judges the quality of the received beam signal. If there is a beam signal whose quality meets the first quality condition among the received beam signals, the beam signal is determined to be the first beam signal, and the beam corresponding to the beam signal is the first beam. The beam corresponding to the beam signal, i.e., the first beam, is used to send a verification signal and a data signal to the base station. The verification signal carries verification information for the base station to verify the identity of the terminal, and the data signal carries the data (such as business data) that the terminal wants to send to the base station.
[0048] The beam signal is sent to the terminal through the beam, so the quality of the beam (such as the attenuation degree of the beam) can be detected by the quality of the beam signal. The higher the quality of the beam, the higher the quality of the data signal sent to the base station. Therefore, the better the quality of the beam signal corresponding to the beam used to send the verification signal and data signal, the better the quality of the verification signal and data signal received by the base station.
[0049] If the terminal receives multiple beam signals from the base station and the qualities of multiple beam signals meet the first quality condition, the terminal may select the beam signal with the best quality as the first beam signal, or it may stop judging the quality of subsequent beam signals after detecting the first beam signal whose quality meets the first quality condition and directly use the beam signal as the first beam signal.
[0050] There are two ways for a terminal to send a verification signal and a data signal to a base station (for the convenience of description, the two ways are referred to as the first way and the second way): the first way is to directly send a data signal after sending the verification signal, and then receive a feedback signal from the base station to complete the process of the terminal accessing the base station, which is also called "two-step access"; the second way is to wait for receiving the feedback signal sent by the base station after sending the verification signal, and after receiving the feedback signal, use the first beam to send a data signal to the base station and wait for the second feedback signal from the base station to complete the process of the terminal accessing the base station, which is also called "four-step access".
[0051] That is to say, the method of the embodiment of the present disclosure can be used for "two-step access" or "four-step access".
[0052] S103: If there is no first beam signal whose quality satisfies the first quality condition in the received beam signals, select a second beam signal from the received beam signals, and use the second beam corresponding to the second beam signal to send a verification signal to the base station.
[0053] If the terminal determines the quality of the received beam signal and finds that there is no beam signal whose quality meets the first quality condition among the received beam signals, that is, there is no beam signal that can be used as the first beam signal, then a beam signal is selected from the received signals as the second beam signal, and the beam corresponding to the beam signal (that is, the second beam) is used to send a verification signal to the base station, and no data signal is sent for the time being.
[0054] S104. Within the first time after using the second beam corresponding to the second beam signal to send a verification signal to the base station, if a first beam signal whose quality meets the first quality condition is received, use the first beam corresponding to the first beam signal to send a verification signal and a data signal to the base station; if the first beam signal whose quality meets the first quality condition is not received, use the second beam corresponding to the second beam signal to send a data signal to the base station.
[0055] After the terminal uses the second beam to send a verification signal to the base station, the base station does not stop sending periodic beam signals to the terminal, and the terminal does not stop receiving the beam signal sent by the base station. If the terminal receives a beam signal that meets the first quality condition within the first time, the beam signal is used as the first beam signal, and the beam corresponding to the first beam signal, that is, the first beam, is used to send a verification signal and a data signal to the base station; if the terminal does not receive a beam signal that meets the first quality condition within the first time, the second beam is used to continue sending data signals to the base station.
[0056] In step S103, if the terminal uses two-step access to send a verification signal to the base station, since no data signal is sent, the feedback signal sent by the base station cannot be received, and the access process is not completed; the terminal receives other beam signals from the base station. If the first beam signal that meets the first quality condition is not received within the first time, there is no need to send a verification signal to the base station again. It only needs to use the second beam to send a verification signal to the base station. After receiving the feedback signal sent by the base station, the access process can be completed.
[0057] Similar to using two-step access to send a verification signal to the base station, if the terminal uses four-step access to send a verification signal to the base station, if the first feedback sent by the base station can be received, the complete access process is not completed because no data signal continues to be sent to the base station; the terminal receives other beam signals from the base station. If the first beam signal that meets the first quality condition is not received within the first time, there is no need to send a verification signal to the base station. It only needs to use the second beam to send a verification signal to the base station. After receiving the feedback signal sent by the base station, the access process can be completed.
[0058] Of course, if the first beam signal that meets the first quality condition is received within the first time, regardless of whether the terminal uses two-step access or four-step access to send a verification signal to the base station, the terminal needs to use the first beam to resend the verification signal and the data signal to the base station.
[0059] According to the method for sending signals provided by the embodiment of the present disclosure, after receiving the beam signal sent by the base station, the beam quality is judged by the beam signal. If there is a beam with good quality at present, the beam is directly used to send the verification signal and the data signal. If there is no beam with good quality at present, other beams are first used to send a verification signal to the base station, and the beam signal sent by the base station is continued to be received within a certain period of time, and it is judged whether there is a beam with good quality in the beam corresponding to the newly received beam signal. If so, the new beam with better quality is used to send the verification signal and the data signal. If not, the previous beam continues to be used to send the data signal to the base station without sending the verification signal again. Through such processing, when a better beam is needed at the beginning, the beam with better quality is directly selected to send the verification signal and the data signal, and the sent data signal has good quality and no delay; when there is no better beam at the beginning, the verification signal is first sent using the currently received beam with the second best quality. If a beam with better quality is available in a short time, the beam with the better quality is directly used, and the sent data signal has good quality and low delay; if there is still no beam with better quality in a short time, the beam with the second best quality continues to be used to send the data signal, which is equivalent to selecting the best quality beam to send the data signal with short delay.
[0060] In some embodiments, selecting the second beam signal from the received beam signals (S103) includes: selecting a beam signal with the best quality from the received beam signals as the second beam signal.
[0061] If the terminal determines the quality of the received beam signal and finds that there is no beam signal whose quality meets the first quality condition among the received beam signals, that is, no beam signal can be used as the first beam signal, then the terminal selects the beam signal with the best quality from the received signals as the second beam signal, and uses the beam corresponding to the beam signal (that is, the second beam) to send a verification signal to the base station, and does not send the data signal for the time being.
[0062] In the signal sending method of the embodiment of the present disclosure, when there is no first beam signal, the terminal uses the second beam signal with the best quality in the current beam, so as to ensure the signal quality as much as possible (that is, the best quality among the existing beams is selected).
[0063] In some embodiments, reference Figure 2 , selecting a second beam signal from the received beam signal (S103) includes: S1031, selecting a second beam signal from the received beam signal whose quality satisfies a second quality condition, and the second quality condition is lower than the first quality condition.
[0064] If the terminal determines the quality of the received beam signal and finds that there is no beam signal whose quality meets the first quality condition among the received beam signals, that is, there is no beam signal that can be used as the first beam signal (that is, there is no beam with "very good" quality), then a beam signal whose quality meets the second quality condition (of course, the second quality condition is lower than the first quality condition) is selected from the received signal as the second beam signal (that is, a beam with "not too bad" quality) and the beam corresponding to the beam signal is used, that is, the second beam, to send a verification signal, and no data signal is sent for the time being.
[0065] Of course, among the multiple beam signals received by the terminal from the base station, the qualities of multiple beam signals may meet the second quality condition, and the terminal can select the beam signal with the best quality as the second beam signal.
[0066] In the signal sending method of the embodiment of the present invention, when there is no first beam signal, the terminal uses a beam signal that meets the second quality condition as the second beam signal, which can ensure that the quality of the selected beam signal at least meets the second quality condition, thereby ensuring that the quality of the beam used to send information is at least "not too bad", avoiding the use of the beam corresponding to a beam signal with too poor quality to send a data signal, resulting in the data signal being unable to be correctly received and processed.
[0067] In some embodiments, reference Figure 2 , selecting a second beam signal (S103) whose quality satisfies a second quality condition from the received beam signals includes: S1032. If there is no second beam signal satisfying the second quality condition in the received beam signals, stop sending the signal.
[0068] If the terminal determines the quality of the received beam signal and finds that there is no beam signal whose quality meets the first quality condition, that is, the first beam signal, nor is there a beam signal whose quality meets the second quality condition (of course, the second quality condition is lower than the first quality condition), then any beam signal currently received will not be selected to send the verification signal corresponding to the beam, but instead the terminal waits to receive the beam signal sent by the base station in the next cycle.
[0069] Doing so can ensure that the terminal ultimately uses the beam corresponding to the beam signal whose quality meets certain conditions to send the data signal, avoiding the use of the beam corresponding to the beam signal with too poor quality to send the data signal, which may cause the data signal to be unable to be correctly received and processed.
[0070] In some embodiments, the beam signal is SSB, the verification signal is a physical layer random access channel signal, and the data signal is a physical layer uplink shared channel signal.
[0071] SSB (Synchronization Signal and PBCH Block) is composed of the original primary synchronization sequence, secondary synchronization sequence, physical broadcast channel and demodulation reference signal, that is, PSS (Primary Synchronization Signal), SSS (Secondary Synchronization Signal), PBCH (Physical Broadcast) and DMRS (Demodulation Reference Signal) are received in four consecutive OFDM (Orthogonal Frequency Division Multiplexing) symbols and then form SSB, which is mainly used for downlink synchronization and is the core of 5G NR (New Radio) downlink synchronization.
[0072] PRACH (Physical Random Access Channel) is mainly used for initialization of network access and for achieving uplink timing synchronization for users (such as terminals) that have not obtained uplink synchronization or have lost uplink synchronization. That is, it is used for the terminal to initiate communication with the base station. The base station can determine the identity of the access terminal and calculate the delay of the terminal by receiving the PRACH signal.
[0073] PUSCH (Physical Uplink Shared Channel) is the main uplink data bearer channel of the physical layer and is used for scheduling and transmitting uplink data. The PUSCH signal can carry control information, service information and other information.
[0074] The terminal accesses the base station through SSB, PRACH signals and PUSCH signals to send service information to the base station.
[0075] Therefore, the sending of the sending signal in the embodiment of the present disclosure may specifically be:
[0076] The base station sends K SSBs in the mth downlink time slot, and these K SSBs correspond to beams in different directions. Due to environmental factors and other factors, the terminal may not receive all K SSBs, and the quality of the received SSBs is also different. Therefore, after receiving the SSB in the downlink time slot, the terminal sets two quality conditions, namely the first quality condition and the second quality condition (the first quality condition is higher than the second quality condition, and satisfying the first quality condition must satisfy the second quality condition), and judges all received SSBs to determine whether their quality meets the first quality condition and the second quality condition.
[0077] If SSB B exists m,k If the first quality condition is met, the terminal uses the same uplink time slot as B in the next uplink time slot (assuming it is the nth uplink time slot). m,k The corresponding beam sends the PRACH signal, and uses the same beam as B in the i1th (i1≥1)th uplink time slot after the uplink time slot in which the PRACH signal is sent, that is, the n+i1th uplink time slot. m,k The corresponding beam sends a PUSCH signal.
[0078] If there is no SSB satisfying the first quality condition, but there is SSB B m,l If the first quality condition is not met but the second quality condition is met, the terminal uses the same uplink time slot as B in the next uplink time slot (assuming it is the nth uplink time slot). m,l The corresponding beam sends the PRACH signal.
[0079] At the same time, the base station continues to send K′ SSBs in each of the j downlink time slots after the mth downlink time slot within the first time period, and these K′ SSBs also correspond to beams in different directions. The beam direction of these K′ SSBs may be the same as or different from the beam direction of the K SSBs sent in the mth downlink time slot. Also due to environmental factors, the terminal may not receive all K′ SSBs, and the quality of the received SSBs may also be different. The terminal continues to judge the received SSB sent by the base station to determine whether its quality meets the first quality condition.
[0080] If there is no SSB B in the SSBs sent in the j downlink time slots after the mth downlink time slot m,k′ If the first quality condition is met, the terminal uses the same signal as B in the next uplink time slot, that is, the n+i2th uplink time slot (i2>1). m,l The corresponding beam sends a PUSCH signal.
[0081] If the SSB sent in the j downlink time slots after the mth downlink time slot contains SSB B m,k′ If the first quality condition is met, the terminal uses the same signal as B in the next uplink time slot, that is, the n+i3th uplink time slot (i3≥1). m,k′ The corresponding beam sends the PRACH signal, and in the i4th (i4≥1)th uplink time slot following the uplink time slot in which the PRACH signal is sent, that is, the n+i3+i4th uplink time slot, the same as B is used. m,k′ The corresponding beam sends a PUSCH signal.
[0082] In some embodiments, the first quality condition is that the reference signal receiving power of the beam signal is greater than a preset first threshold.
[0083] After receiving the beam signal, the terminal calculates the RSRP (Reference Signal Receiving Power) of the received beam signal. RSRP is the average value of the signal power received on all REs (resource elements) carrying the reference signal in a certain symbol. It is a key parameter that can represent the strength of the wireless signal in the LTE network. The strength of the beam signal can be judged by the RSRP of the beam signal. The stronger the strength of the beam signal, the better its quality is, and the corresponding beam quality is naturally better.
[0084] If the RSRP of the beam signal is greater than a preset first threshold, it indicates that the strength of the beam signal is strong enough to meet the requirements of the terminal to send a data signal, so the beam signal can be set as the first beam signal.
[0085] Similarly, the second quality condition is that the reference signal receiving power of the beam signal is greater than a preset second threshold, and the second threshold is lower than the first threshold.
[0086] If the RSRP of the beam signal is less than the preset first threshold but greater than the second threshold, it means that the data signal sent using the beam corresponding to the beam signal can be received by the base station, but it is not the optimal choice. If there is no better choice, the data signal can be sent using the beam corresponding to the beam signal.
[0087] Of course, other values that can represent the quality of beam signals, such as SINR (Signal to Interference plus Noise Ratio) and the like, may also be used.
[0088] In some embodiments, the first time is a time slot in which the base station sends a beam signal.
[0089] That is, after the terminal uses the second beam to send a verification signal to the base station, the base station still sends a beam signal in a different direction in the next time slot of the time slot in which the second beam is sent, and the terminal does not stop receiving the beam signal sent by the base station. If there is a beam signal that meets the first quality condition in the beam signal sent in the time slot, that is, the first beam signal, the beam corresponding to the first beam signal, that is, the first beam, is used to send a verification signal and a data signal to the base station; if there is no first beam signal that meets the first quality condition in the beam signal sent in the time slot, the second beam is used to continue sending data signals to the base station.
[0090] The terminal can select the beam for sending data signals at the latest within the first time after receiving the beam signal sent by the base station for the first time. That is to say, the user's delay is at most the first time. One time slot as the first time is an acceptable delay for the user.
[0091] Second, refer to Figure 3 , the present disclosure embodiment provides a terminal, which specifically includes:
[0092] A receiving module, used for receiving at least one beam signal from a base station, each beam signal corresponding to a beam;
[0093] A first sending module is used to send a verification signal and a data signal to a base station using a first beam corresponding to the first beam signal when the received beam signal includes a first beam signal whose quality satisfies a first quality condition, wherein the verification signal is used by the base station to verify the identity of the terminal;
[0094] A second sending module is used to select a second beam signal from the received beam signals when there is no first beam signal whose quality satisfies the first quality condition in the received beam signals, and use the second beam corresponding to the second beam signal to send a verification signal to the base station;
[0095] The third sending module is used to send a verification signal and a data signal to the base station using the first beam corresponding to the first beam signal within the first time after the second beam corresponding to the second beam signal is used to send a verification signal to the base station, when the first beam signal whose quality meets the first quality condition is received; and when the first beam signal whose quality meets the first quality condition is not received, use the second beam corresponding to the second beam signal to send a data signal to the base station.
[0096] According to the terminal provided by the embodiment of the present disclosure, after receiving the beam signal sent by the base station, the beam quality is judged by the beam signal. If there is a beam with good quality at present, the beam is directly used to send a verification signal and a data signal. If there is no beam with good quality at present, other beams are first used to send a verification signal to the base station, and the beam signal sent by the base station is continued to be received within a certain period of time, and it is judged whether there is a beam with good quality in the beam corresponding to the newly received beam signal. If so, the new beam with better quality is used to send the verification signal and the data signal. If not, the previous beam continues to be used to send the data signal to the base station without sending the verification signal again. Through such processing, when a better beam is needed at the beginning, the beam with better quality is directly selected to send the verification signal and the data signal, and the sent data signal has good quality and no delay; when there is no better beam at the beginning, the verification signal is first sent using the currently received beam with the second best quality. If a beam with better quality is available in a short time, the beam with the better quality is directly used, and the sent data signal has good quality and low delay; if there is still no beam with better quality in a short time, the beam with the second best quality continues to be used to send the data signal, which is equivalent to selecting the best quality beam to send the data signal with short delay.
