Description

[Technical Field]

[0001] This application claims priority to a Chinese patent application bearing application number 202211053984.0, filed with the China Patent Office on August 31, 2022, the entire contents of which are incorporated herein by reference.

[0002] The present application relates to the technical field of wireless communication, for example, to a signal generation method, an electronic device, and a storage medium. [Background technology]

[0003] As wireless communication technology develops, device power consumption requirements are increasing. For 5th Generation Mobile Communication Technology (5G) systems, in addition to latency, reliability, and availability, energy efficiency of user equipment (UE) is also crucial. Currently, 5G devices may need to be charged weekly or daily depending on the individual's usage time. Typically, 5G devices consume tens of milliwatts of power in the Radio Resource Control (RRC) idle or inactive state and hundreds of milliwatts in the RRC connected state. Extending battery life is a necessary condition for improving energy efficiency and user experience. Power consumption depends on the configured wake-up cycle length, such as the paging cycle. To meet the battery life requirement, the expensive extended discontinuous reception (eDRX) cycle is expected to be used, but this will result in high latency, making it unsuitable for services that require both battery life and low latency. To extend battery life, the current field has introduced a Low Power Wake Up (LP-WUS) mechanism, in which a user receives a low power wake up signal using a separate receiver, which then wakes up the master radio for data transmission and reception. If the UE does not detect the low power wake up signal, the master receiver remains in a deep sleep state, further reducing the power consumption of the terminal. However, currently, there is no method for generating a low power wake up signal. Summary of the Invention [Problem to be solved by the invention]

[0004] The main objective of the embodiments of the present application is to provide a signal generation method, electronic device, and storage medium for generating at least a low-power wake-up signal, realizing ultra-low-power wake-up of a device in a deep sleep state, and reducing standby power consumption to improve the battery life of the device.

[0011] FIG. 1 is a flowchart of a signal generation method according to an embodiment of the present application, which is applicable to signal generation, and the method can be performed by a signal generation device, which can be realized in software and / or hardware. Referring to FIG. 1, the method according to the embodiment of the present application includes the following steps:

[0012] In step 110, the signal is set to occupy at least one time-domain symbol in the time domain and at least one subcarrier in the frequency domain, and the bandwidth in the frequency domain includes N subcarriers, where N is 1 or greater.

[0013] In an embodiment of the present application, a signal occupying at least one time-domain symbol in the time domain and at least one subcarrier in the frequency domain can be configured, and the signal can be used for ultra-low power wake-up. The bandwidth of the signal in the frequency domain can be configured with N subcarriers.

[0014] In step 120, the information to be carried on the N subcarriers is determined.

[0015] In the embodiment of the present application, the information carried on the N subcarriers occupied by the signal can be determined.

[0016] In some embodiments, determining information to be carried on the N subcarriers comprises: The upper boundary N1 subcarriers in the bandwidth are defined as a guard bandwidth, where N1 is greater than or equal to 0 and less than or equal to N; The guard bandwidth is N2 subcarriers at the lower boundary of the bandwidth, where N2 is greater than or equal to 0 and less than or equal to N; N3 subcarriers at the center of the N subcarriers are not filled with data or are filled with data of 0, and N3 is greater than or equal to 0 and less than or equal to N; and filling K subcarriers of the N subcarriers with data, where K is greater than or equal to 1 and less than or equal to N.

[0017] In some embodiments of the present application, N1 subcarriers are selected at the upper boundary of the bandwidth occupied by the signal to form a guard bandwidth, where N1 may be an integer greater than or equal to 0 and less than or equal to the total number N of subcarriers occupied by the signal. Correspondingly, in one embodiment, N2 subcarriers are selected at the lower boundary of the bandwidth occupied by the signal to form a guard bandwidth, where N2 may be an integer greater than or equal to 0 and less than or equal to N. In some other embodiments, N3 subcarriers are selected in the center portion of the bandwidth occupied by the signal to be unfilled with data or filled with zeros. In some other embodiments, K subcarriers can be selected from the N subcarriers to be filled with data, where K may be less than or equal to N. Based on this, some embodiments may be configured with one or more of the above embodiments.

[0018] In some embodiments, the locations of the K subcarriers are: the remaining subcarriers after removing N1 subcarriers and N2 subcarriers from the N subcarriers; The subcarriers include at least one of N1 subcarriers, N2 subcarriers, and the subcarriers remaining after removing N3 subcarriers from the N subcarriers.

[0019] In some embodiments of the present application, K subcarriers can be selected from N subcarriers of a signal to be filled with data, and the K subcarriers may be the remaining subcarriers after removing the N1 and N2 subcarriers determined as the guard bandwidth in the above embodiment. In some other embodiments, the K subcarriers to be filled with data in a signal may be the remaining subcarriers after removing the subcarriers determined as the guard bandwidth and the subcarriers that are not filled with data or have zero data to be filled.

[0020] FIG. 2 is an exemplary diagram of a signal generation method according to an embodiment of the present application. Referring to FIG. 2, in this embodiment, the LP-WUS may occupy at least one time-domain symbol in the time domain. The bandwidth occupied by the LP-WUS in the frequency domain may include N subcarriers. Referring to FIG. 2, among the N subcarriers, N1 and N2 subcarriers may be set as upper and lower boundary guard bandwidths, respectively. The guard bandwidths may not transmit information. N3 subcarriers at the center of the N subcarriers may be selected to be unfilled with data or filled with 0 data. The remaining K subcarriers may be used to transmit the LP-WUS.

[0021] 3 is an exemplary diagram of another signal generation method according to an embodiment of the present application. Referring to FIG. 3, in this embodiment, the LP-WUS may occupy at least one time-domain symbol in the time domain. The bandwidth occupied by the LP-WUS in the frequency domain may include N subcarriers. Among the N subcarriers, N1 and N2 subcarriers may be set as upper and lower boundary guard bandwidths, respectively, where the guard bandwidths may not transmit information. The remaining K subcarriers may be used to transmit the LP-WUS.

[0022] In some embodiments, the K subcarrier locations are determined by: After removing N1 subcarriers and N2 subcarriers from the N subcarriers, the remaining subcarriers are divided into K subcarrier groups, and each subcarrier group includes G subcarriers, where G is an integer equal to or greater than 1; and selecting one subcarrier from each of the K subcarrier groups to form K subcarriers.

[0023] In this embodiment, the K subcarriers can be determined by removing N1 subcarriers determined as the upper boundary guard bandwidth and N2 subcarriers determined as the lower boundary guard bandwidth from the N subcarriers, and then equally dividing the remaining subcarriers into K subcarrier groups, where each subcarrier group may include G subcarriers, where G is an integer greater than or equal to 1. One subcarrier can be selected from each of the K divided subcarrier groups, and the selected K subcarriers can be used to fill data.

[0024] 4 is an exemplary diagram of another signal generation method according to an embodiment of the present application. Referring to FIG. 4, the LP-WUS may occupy at least one time-domain symbol in the time domain. The bandwidth occupied by the LP-WUS in the frequency domain may include N subcarriers. Among the N subcarriers, N1 and N2 subcarriers may be set as upper and lower boundary guard bandwidths, respectively, where the guard bandwidths may not transmit information. Of the N subcarriers occupied by the signal, K subcarriers may be determined among the remaining subcarriers and used to fill data. After removing N1 and N2, the subcarriers are divided into K subcarrier groups, each of which includes G subcarriers. One subcarrier is selected from each subcarrier group to form the K subcarriers and used to fill data.

[0025] In some other embodiments, the K subcarrier locations are determined by: Divide the N subcarriers into K subcarrier groups, each subcarrier group containing G subcarriers, where G is an integer greater than or equal to 1; and selecting one subcarrier from each of the K subcarrier groups to form K subcarriers.

[0026] In an embodiment of the present application, the N subcarriers occupied by the signal can be divided into K subcarrier groups, and each subcarrier group may include G subcarriers. One subcarrier can be selected from each of the K subcarrier groups to form the K subcarriers used for data filling.

[0027] FIG. 5 is an exemplary diagram of another signal generation method according to an embodiment of the present application. Referring to FIG. 5, the LP-WUS may occupy at least one time-domain symbol in the time domain. The bandwidth occupied by the LP-WUS in the frequency domain may include N subcarriers. The N subcarriers may be divided into K subcarrier groups. Each subcarrier group may include G subcarriers. One subcarrier may be selected in each subcarrier group to form the K subcarriers and fill them with data.

[0028] In some embodiments, each of the subcarriers constituting the K subcarriers has the same index within each of the subcarrier groups.

[0029] In the present embodiment, the subcarriers determined to be used for data filling may have the same index within each subcarrier group.

[0030] In some other embodiments, if a subcarrier among the selected K subcarriers belongs to the N3 subcarriers, no data is filled in the selected subcarrier, or the data filled is 0.

[0031] In an embodiment of the present application, if a subcarrier belongs to the selected K subcarriers and also belongs to N3 subcarriers in which the central data of the N subcarriers is not filled or the filled data is 0, then the subcarrier is not filled with data or the filled data is 0.

[0032] In some other embodiments, if a subcarrier among the K selected subcarriers belongs to the N1 subcarriers, no data is filled in the selected subcarrier, or the data filled is 0.

[0033] In the embodiment of the present application, if there is one subcarrier among the K subcarriers selected to be used for data filling that falls within the range of N1 subcarriers of the upper boundary guard bandwidth, no data is filled in that subcarrier or the data to be filled is 0.

[0034] In some other embodiments, if a subcarrier among the selected K subcarriers belongs to the N2 subcarriers, no data is filled in the selected subcarrier, or the data filled is 0.

[0035] In the embodiment of the present application, for the selected K subcarriers, if the K subcarriers fall within the range of N2 subcarriers of the lower boundary guard bandwidth of the signal, no data is filled in the subcarriers or the data filled is 0.

[0036] In one embodiment, when the signal supports at least two subcarrier spacings, the setting of G is: The subcarrier spacing is f sc and 2 -n f sc and the subcarrier spacing is f sc If G is set to y, the subcarrier spacing is 2 -n f sc When G is y 2 n where y is an integer greater than or equal to 1 and n is an integer greater than or equal to 1.

[0037] In the embodiment of the present application, the signal can support transmission of multiple subcarrier spacings, and the value of G in each subcarrier group can include the following: sc and 2 -n fsc and the subcarrier spacing is f sc If G is set to y, the subcarrier spacing is 2 -n f sc When G is y 2 n where y is an integer greater than or equal to 1 and n is an integer greater than or equal to 1.

[0038] In some embodiments, G is set to: When the subcarrier spacing is 30 KHz, G is set to 1, and correspondingly, when the subcarrier spacing is 15 KHz, G is set to 2; If the subcarrier spacing is 60 KHz, G is set to 1, and correspondingly, if the subcarrier spacing is 30 KHz, G is set to 2, and if the subcarrier spacing is 15 KHz, G is set to 4.

[0039] FIG. 6 is an exemplary diagram of another signal generation method according to an embodiment of the present application. Referring to FIG. 6, in an Orthogonal Frequency Division Multiplexing (OFDM) wireless communication system, the downlink channel system bandwidth is BW1 (Hz) and supports the transmission of a low-power wake-up signal. Here, the LP-WUS occupies at least one time-domain symbol in the time domain. The bandwidth occupied by the LP-WUS in the frequency domain is BW2=1.08 MHz. If the subcarrier spacing set by the LP-WUS is 30 kHz, the LP-WUS occupies 36 subcarriers in the frequency domain. One physical resource block (PRB) can be defined as including 12 subcarriers. In this case, the LP-WUS occupies three PRBs in the frequency domain. As shown in FIG. 6, N1=N2=3 subcarriers are set as guard bandwidths, where no information is transmitted within the guard bandwidth. The number of subcarriers that can be used to transmit the LP-WUS is 36-3=30. In this embodiment, if G=1, that is, the number of subcarriers that the LP-WUS occupies in the frequency domain during transmission is 30, that is, K=30. The data filled into the K=30 subcarriers is a sequence S30 of length 30, where S30=[s0, s1, s2, s3..., s 29 ] is written as follows.

[0040] In another example, if the subcarrier spacing set by the LP-WUS is 15 kHz, the bandwidth occupied by the LP-WUS in the frequency domain is BW2 = 1.08 MHz, in this case, the LP-WUS occupies 72 subcarriers in the frequency domain. N1 = N2 = 6 subcarriers are set as guard bandwidths, so that the maximum number of subcarriers available for transmitting the LP-WUS is 72 - 12 = 60.

[0041] In this example, LP-WUS also generates a sequence of length 30, S30=[s0, s1, s2, s3 ......, s 29] is used. When the subcarrier spacing is 30 kHz, G = y = 1, so 30 / 15 = 2, and n = 1, i.e., G = y2 n = 1 * 2 = 2, that is, each subcarrier group contains two subcarriers. The UE selects one subcarrier in one subcarrier group as the subcarrier to be used when transmitting the LP-WUS. Thus, the number of subcarriers occupied in the frequency domain when transmitting the LP-WUS is 30. Similarly, a sequence of length 30, S30 = [s0, s1, s2, s3……, s 29 ] is used.

[0042] In some embodiments, the data to be filled into the K subcarriers is a sequence S of length 2*M, which is composed of two sequences of length M each, where S=[A M ,B M ] and where A M is the first sequence of length M, and B M is a second sequence of length M, where K=2*M.
