Description

Information sending method, electronic device and storage medium Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to an information sending method, electronic device, and storage medium. Background Art

[0002] In communication systems, latency, reliability, and availability are key indicators that influence communication quality. With the advancement of communication technologies, the energy efficiency of user equipment (UE) is becoming increasingly crucial. Currently, 5G devices consume tens of milliwatts of power in the Radio Resource Control (RRC) idle or inactive state and hundreds of watts in the RRC connected state. Therefore, 5G devices often require weekly or daily charging depending on user habits. Extending battery life is essential for improving energy efficiency and user experience. Power consumption in general systems is primarily determined by the length of configured wake-up cycles, such as the paging cycle. To meet battery life requirements, the high-cost Extended Discontinuous Reception (eDRX) cycle is expected to be used, resulting in high latency and making it unsuitable for services that require both battery life and low latency. Therefore, the Low Power Wake-Up Signal (LP-WUS) mechanism has emerged. That is, the user uses a separate receiver to receive the low-power wake-up signal, which is used to wake up the main radio device (Main Radio) for data transmission and reception. When the UE does not detect the low-power wake-up signal, the main receiver is in a deep sleep state, further reducing the power consumption of the terminal. The LP-WUS waveform is generated using binary amplitude keying (On and Off Keying, OOK) modulation. The generated signal can be OOK-based LP-WUS. When the number of subcarriers occupied by this signal in the frequency domain is greater than one, it is called multiple subcarrier binary amplitude keying (Multiple Sub Carrier-OOK based LP-WUS, MC-OOK based L-WUS) based on low-power wake-up information. There is no clear solution for how to send this signal. Summary of the Invention

[0003] The embodiments of the present application aim to provide an information sending method, an electronic device, and a storage medium to solve the problem of generating a low-power wake-up signal based on OOK modulation, thereby transmitting the low-power wake-up signal using multiple subcarriers, thereby reducing the power consumption of the device system and improving the user experience.

[0050] Currently, there are two common MC-OOK-based LP-WUS generation methods. The first MC-OOK-based LP-WUS generation method can generate a time-domain representation of M MC-OOK-based LP-WUS symbols, where M is greater than or equal to 1. (See Figure 1 ) This generation method includes:

[0051] Step 1: The data information sent on M OOK symbols is S M , such as source information, verification information, filling information, etc., SM Alternatively, the data information may be obtained through data processing. The processing may include at least one of the following: blocking, repetition, bit-level repetition, source coding, channel coding, modulation, interleaving, adding padding bits, adding cyclic redundancy check (CRC) bits, and rate matching. M =[s0, s1, s2, s3..., s M-1 ] and its length is M, where the data information S M It can be called coded bit information, coded sequence information or code word information.

[0052] Step 2: Use the following formula to convert S M Convert to data information Q K , where Q K The length of is K, where K is greater than or equal to 1.

[0053] or

For a vector X, FFTSHIFT(X) swaps the left and right halves of X or the top and bottom halves of X. For a matrix X, FFTSHIFT(X) swaps the first and third quadrants, or the second and fourth quadrants.

For a vector X, FFTSHIFT(X) swaps the left and right halves of X or the top and bottom halves of X. For a matrix X, FFTSHIFT(X) swaps the first and third quadrants, or the second and fourth quadrants.

When the user terminal switches the partial bandwidth, if the target partial bandwidth to be switched has the configuration of the first information, the target partial bandwidth is activated, or if the target partial bandwidth to be switched has the configuration of the first information, an activation signal of the first information is sent.

[0401] The time when the user terminal activates the target portion of bandwidth and activates the first information on the target portion of bandwidth;

[0402] The user terminal activates the target portion of the bandwidth after a time period is increased, and activates the first information on the target portion of the bandwidth.

[0406] After the time of receiving the information of switching to the target bandwidth portion is increased by one time period;

[0407] The moment of triggering the switching of the target portion of bandwidth;

[0408] The time period after triggering the switching of the target bandwidth is increased by one time period;

[0409] The time when the user terminal activates the target portion of bandwidth;

[0410] After the user terminal activates the target portion of bandwidth and then increases the time period;

[0411] The time when the user terminal activates the target portion of bandwidth and activates the first information on the target portion of bandwidth;

[0412] The user terminal activates the target portion of the bandwidth after a time period is increased, and activates the first information on the target portion of the bandwidth.

[0413] Based on the above application embodiment, during the switching of partial bandwidth, the resources of the preset signal of the source partial bandwidth conflict with the information in the switching of partial bandwidth in the time domain, and the preset signal on the source partial bandwidth is not activated.

[0414] For example, during the BWP switching process, if the LP-WUS resource of the source BWP conflicts with the information in the BWP switching process in the time domain, the LP-WUS on the source BWP is not activated.
