[0149] Figure 2A is an interactive schematic diagram of a cell reselection method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiments of the present disclosure relate to a cell reselection method, which includes:

[0150] Step S2101: The network device sends the first configuration information to the terminal.

[0151] In some embodiments, the terminal receives first configuration information sent by the network device. It should be noted that this embodiment is illustrated by example of the network device sending the first configuration information to the terminal. In another embodiment, the network device does not send the first configuration information selectively, but rather sends it via broadcast, so all terminals located on the network device can receive the first configuration information. Optionally, the first configuration information is carried in system information and sent to the terminal by the network device via broadcast.

[0152] In some embodiments, the first configuration information is used to configure a low-power reference signal and / or a low-power wake-up signal. Optionally, the first configuration information is used to configure a low-power reference signal. Optionally, the first configuration information is used to configure a low-power wake-up signal. Optionally, the first configuration information is used to configure both a low-power reference signal and a low-power wake-up signal. The low-power wake-up signal is used to wake up the terminal's main receiver. Optionally, both the low-power wake-up signal and the low-power reference signal are received by the terminal's low-power receiver.

[0153] Optionally, this low-power wake-up signal is LP WUS (Low Power Wake Up Signal). It should be noted that LP-WUR can support at least two types. One type of LP-WUR only supports envelope detection of the OOK (On Off Keying) symbols of LP WUS, hereinafter referred to as OOK LR. This type of receiver has relatively poor link performance. The other type of LP-WUR can detect the OFDM time-domain or frequency-domain sequence (i.e., overlaid OFDM sequence) carried by the OOK symbols of LP WUS, thereby improving link performance, hereinafter referred to as OFDM LR. OFDM LR may also be able to detect PSS / SSS sequences in existing protocols. However, if the PSS / SSS is not within the frequency band supported by OFDM LR, OFDM LR cannot receive the PSS / SSS.

[0154] For example, the low-power reference signal may include, but is not limited to, LP-SS (Low Power Synchronization Signal) and / or LP WUS. Alternatively, LP-SS and / or LP WUS can be considered as a type of low-power reference signal. It should be noted that the LP-SS and / or LP WUS in the embodiments of this disclosure are merely illustrative examples, and the embodiments of this disclosure do not limit the low-power reference signal to LP-SS and / or LP WUS; the low-power reference signal may also be other signals.

[0155] In some embodiments, the name of the first configuration information is not limited, and it may be, for example, signal configuration information, configuration information, information configuration, etc. This disclosure does not limit this.

[0156] Optionally, the first configuration information includes at least one of the following:

[0157] (1) Frequency domain information.

[0158] In some embodiments, frequency domain information is used to indicate the frequency domain location of a low-power reference signal and / or a low-power wake-up signal (LP WUS).

[0159] Optionally, the terminal can determine whether the low-power reference signal and / or low-power wake-up signal of the neighboring cell is a frequency supported by the terminal's low-power receiver based on the frequency domain information. It can also determine the frequency domain position of the low-power reference signal and / or low-power wake-up signal of the neighboring cell based on the frequency domain information, thereby avoiding the delay and power consumption of the low-power receiver blindly searching for the low-power reference signal and / or low-power wake-up signal of the neighboring cell at the candidate frequency domain position.

[0160] (2) Time domain information.

[0161] In some embodiments, time-domain information is used to indicate the time-domain location of a low-power reference signal and / or a low-power wake-up signal.

[0162] Optionally, the time-domain information includes at least one of period, time-domain offset value, or listening window length. Optionally, if the neighboring cell's time is not synchronized with the current serving cell, it may also include synchronization time offset information between the neighboring cell and the current serving cell. Optionally, the terminal can determine the period for listening to the low-power reference signal based on the time-domain location information of the neighboring cell's low-power reference signal. The terminal can also determine the period for listening to the low-power wake-up signal after camping on the neighboring cell based on the time-domain location information of the neighboring cell's low-power wake-up signal.

[0163] (3) OFDM sequence.

[0164] In some embodiments, the OFDM sequence is carried by a low-power reference signal and used to measure the low-power reference signal.

[0165] Optionally, the OFDM sequence includes an overlaid OFDM sequence and sequence parameters of the overlaid OFDM sequence. The sequence parameters determine the values ​​of each element in the overlaid OFDM sequence. The terminal can determine whether and how to measure the reception quality of neighboring cells by detecting the overlaid OFDM sequence based on whether the neighboring cell's LP-SS or LP WUS is configured with an overlaid OFDM sequence and which overlaid OFDM sequence is configured. For example, if the neighboring cell is configured with an overlaid OFDM sequence, the terminal can choose to measure the reception quality by performing correlation demodulation on the OFDM sequence within a time-domain symbol in the frequency or time domain. If the terminal does not know which specific OFDM sequence is used, it may need to perform a blind search among multiple candidate sequences to obtain the correlation detection result. If the terminal knows which specific OFDM sequence is used, it can directly obtain the correlation detection result for that OFDM sequence without needing to perform a blind search among multiple candidate sequences.

[0166] (4) Power information.

[0167] In some embodiments, power information is used to indicate the transmission power of a low-power reference signal and / or a low-power wake-up signal.

[0168] Optionally, the power information refers to the offset between the transmission power of the low-power reference signal and / or low-power wake-up signal of the neighboring cell and the set reference power. The set reference power is the transmission power of the SSB (Synchronization Signaling Block) received by the neighboring cell, or a power configured in other ways; this disclosure does not limit this.

[0169] (5) Multibeam information.

[0170] In some embodiments, multi-beam information is used to indicate the number of beams of the low-power reference signal. Optionally, the terminal can determine the signal reception quality of a neighboring cell based on the low-power reference signal beam with the best measurement results among the neighboring cells. Optionally, the terminal can also determine the signal reception quality of a neighboring cell based on the measurement results of multiple low-power reference signal beams in the neighboring cell, for example, by using the average value of the measurement results of multiple low-power reference signal beams in the neighboring cell; it can also determine the signal reception quality of a neighboring cell based on the non-uniform filtering value of the measurement results of multiple low-power reference signal beams in the neighboring cell.

[0171] In step S2102, the network device sends the second configuration information to the terminal.

[0172] In some embodiments, the terminal receives second configuration information sent by the network device. It should be noted that this embodiment is illustrated by example of the network device sending second configuration information to the terminal. In another embodiment, the network device does not send the second configuration information selectively, but rather sends it via broadcast, so all terminals located on the network device can receive the second configuration information. Optionally, the second configuration information is carried in system information and sent to the terminal by the network device via broadcast.

[0173] Optionally, the second configuration information is used to configure at least one of a first quality threshold, a second quality threshold, or a third quality threshold. The first quality threshold is used by the terminal to determine whether the measurement result of the low-power reference signal is greater than a first quality threshold. The second quality threshold is used by the terminal to determine whether the difference between the measurement result of the low-power reference signal and the highest measurement result is less than a second quality threshold. The third quality threshold is used by the terminal to determine whether the measurement result of the low-power reference signal of the current serving cell is less than a third quality threshold.

[0174] It should be noted that the execution order of steps S2101 and S2102 in this embodiment is not limited, and step S2102 can be executed before step S2101.

[0175] In some embodiments, the first configuration information and the second configuration information may be the same information or different information, and this disclosure does not limit this.

[0176] In step S2103, the terminal receives a low-power reference signal from at least one neighboring cell based on a low-power receiver.

[0177] In some embodiments, the terminal can obtain the configuration of the low-power reference signal based on the first configuration information, and then receive the low-power reference signal sent by the neighboring cell based on the first configuration information.

[0178] In some embodiments, the low-power reference signal includes a cell identifier, which is used to indicate neighboring cells. In this embodiment, after receiving the low-power reference signal, the terminal can determine the cell that sent the low-power reference signal.

[0179] In step S2104, the terminal measures the low-power reference signal of the neighboring cell to obtain the measurement result of the low-power reference signal.

[0180] In this embodiment of the disclosure, after the terminal receives the low-power reference signal of the neighboring cell, it can measure the received low-power reference signal of the neighboring cell to obtain the measurement result.

[0181] In some embodiments, the measurement results of the low-power reference signal include RSRP (Reference Signal Receiving Power), RSRQ (Reference Signal Receiving Quality), SINR (Signal to Interference plus Noise Ratio), or other results, which are not limited in this disclosure.

[0182] In step S2105, the terminal performs cell reselection based on the measurement results of the low-power reference signal of the neighboring cell to determine the cell where the terminal will camp.

[0183] In some embodiments, the camping cell refers to the cell that the terminal accesses after performing cell reselection. Alternatively, it can be understood as the cell that the terminal is to access after performing cell reselection, or it can be understood as the serving cell after the terminal performs cell reselection.

[0184] In some embodiments, the terminal performs cell reselection based on the measurement results of low-power reference signals from neighboring cells to determine the cell to be camped, including: determining at least one candidate cell based on the measurement results of low-power reference signals from neighboring cells, performing cell reselection from the at least one candidate cell, and determining the cell to be camped. In embodiments of this disclosure, the low-power reference signal may be transmitted by multiple neighboring cells, or it can be said that each neighboring cell may transmit a low-power reference signal, and the terminal may determine at least one candidate cell based on the measurement results of the low-power reference signal transmitted by each neighboring cell.

[0185] In some embodiments, at least one candidate cell includes at least one of the following:

[0186] (1) Neighboring cells whose measurement results are greater than the first quality threshold for low-power reference signals.

[0187] In some embodiments, the first quality threshold is configured by second configuration information sent by the network device. Optionally, if the first quality threshold is RSRP, the terminal needs to measure the RSRP of the low-power reference signal when measuring the low-power reference signal. Optionally, if the first quality threshold is RSRQ, the terminal needs to measure the RSRQ of the low-power reference signal when measuring the low-power reference signal.

[0188] In some embodiments, the terminal identifies neighboring cells of a low-power reference signal whose measurement result is greater than a first quality threshold as candidate cells.

[0189] (2) Neighboring cells of a low-power reference signal whose measurement result is greater than the first quality threshold and whose difference with the highest measurement result is less than the second quality threshold.

[0190] In some embodiments, the second quality threshold is configured by second configuration information sent by the network device. Optionally, the second quality threshold can also be understood as a range, for example, the second quality threshold can be referred to as a quality range, and neighboring cells within the range specified by the quality range are those with symbol requirements.

[0191] In some embodiments, if the highest measurement result is measurement result A, and the difference between measurement result B and measurement result A is less than a second quality threshold, and measurement result B is greater than a first quality threshold, then the neighboring cell of the low-power reference signal corresponding to measurement result B can be used as a candidate cell.

[0192] In some embodiments, cell reselection from at least one candidate cell to determine the stationary cell includes: determining the candidate cell with the highest measurement result among the at least one candidate cell as the stationary cell. In this embodiment of the disclosure, the candidate cell with the highest measurement result has the best communication quality; therefore, determining the candidate cell with the highest measurement result as the stationary cell can ensure the reliability of terminal communication.

[0193] In some embodiments, cell reselection from at least one candidate cell to determine the stationary cell includes: determining the candidate cell with the most first beams among the at least one candidate cells as the stationary cell. Here, the first beam refers to the beam in the low-power reference signal whose beam measurement result is greater than a first quality threshold.

[0194] In this embodiment of the disclosure, the number of beams with beam measurement results greater than the first quality threshold in the low-power reference signal is the largest, indicating that the communication quality of the cell corresponding to the low-power reference signal is the best. Therefore, the candidate cell with the largest number of first beams among at least one candidate cell can be determined as the stationary cell to ensure the reliability of terminal communication.

[0195] In some embodiments, determining the candidate cell with the most first beams among at least one candidate cell as the stationary cell includes: the candidate cell with the most first beams among at least one candidate cell includes multiple candidate cells, and the candidate cell with the highest measurement result among the multiple candidate cells with the most first beams is determined as the stationary cell.

[0196] In this embodiment of the disclosure, the number of beams with beam measurement results greater than the first quality threshold in the low-power reference signal is the largest, indicating that the communication quality of the cell corresponding to the low-power reference signal is the best. However, since there are multiple candidate cells with the largest number of first beams in at least one candidate cell, the candidate cell with the highest measurement result is selected as the camping cell to ensure that the communication quality of the terminal is the highest when communicating in the camping cell.

[0197] In some embodiments, cell reselection from at least one candidate cell to determine the stationary cell includes: determining the candidate cell with the highest priority among the at least one candidate cells as the stationary cell. In this embodiment, each candidate cell corresponds to a priority, so candidate cells can be selected and determined as the stationary cell according to their priority.

[0198] In some embodiments, the highest priority candidate cells include multiple cells, and determining the highest priority candidate cell among at least one candidate cell as the stationed cell includes: determining the candidate cell with the highest measurement result among the multiple highest priority candidate cells as the stationed cell.

[0199] In some embodiments, the highest priority candidate cells include multiple cells, and determining the highest priority candidate cell among at least one candidate cell as the stationary cell includes: determining the candidate cell with the most first beams among the multiple highest priority candidate cells as the stationary cell, where the first beam refers to the beam in the low-power reference signal whose beam measurement result is greater than a first quality threshold.

[0200] In some embodiments, determining the candidate cell with the most first beams among the multiple candidate cells with the highest priority as the stationary cell includes: the multiple candidate cells with the most first beams among the multiple candidate cells with the highest priority include multiple candidate cells, and determining the candidate cell with the highest measurement result among the multiple candidate cells with the most first beams as the stationary cell.

[0201] In some embodiments, the candidate cell with the highest measurement result includes multiple cells, and determining the candidate cell with the highest measurement result as the stationary cell includes: determining the candidate cell with the smallest power offset value among the multiple candidate cells with the highest measurement result as the stationary cell.

[0202] It should be noted that the embodiments disclosed herein are based on the scenario where the measurement result of the low-power reference signal is greater than the first quality threshold. In another embodiment, if the measurement results of the low-power reference signals of at least one neighboring cell are all less than the first quality threshold, the terminal's main receiver is activated.

[0314] Figure 6 is a flowchart illustrating a cell reselection method according to an embodiment of the present disclosure. As shown in Figure 6, the present disclosure relates to a cell reselection method, which includes:

[0315] In step S6101, the base station broadcasts the LP-SS / LP WUS configuration information of neighboring cells through system information.

[0316] In some embodiments, the configuration information includes LP-SS / LP WUS configuration information of one or more neighboring cells.

[0317] In some embodiments, the LP-SS / LP WUS configuration information may include the frequency domain location information, time domain location information, power information, overlaid OFDM sequence information, and multi-beam information of the LP-SS / LP WUS.

[0318] Optionally, the frequency domain location includes the frequency domain location where the LP-SS is located. The UE can use this information to determine whether the LP-SS / LP WUS of the neighboring cell is a frequency supported by the UE's LR, and can also use this information to determine which frequency domain location to listen to the LP-SS / LP WUS of the neighboring cell, thus avoiding the latency and power consumption of the LR blindly searching for the LP-SS / LP WUS of the neighboring cell in the candidate frequency domain location.

[0319] Optionally, the time-domain location information includes period, time-domain offset, and listening window size. If the time of neighboring cells is not synchronized with the current cell, the synchronization time offset information between the neighboring cells and the current cell can also be included. The UE can determine the period for listening to LP-SS based on the LP-SS time-domain location information of neighboring cells. The UE can also determine the period for listening to LP WUS after camping on a neighboring cell based on the LP WUS time-domain location information of neighboring cells.

[0320] Optionally, the overlaid OFDM sequence information includes: whether an overlaid OFDM sequence exists, and the sequence parameters of the overlaid OFDM sequence. The required sequence parameters are used to determine the values ​​of each element in the overlaid OFDM sequence. The UE can determine whether and how to measure the reception quality of a neighboring cell by detecting an overlaid OFDM sequence based on whether the neighboring cell's LP-SS / LP WUS is configured with an overlaid OFDM sequence and which overlaid OFDM sequence is configured. For example, if the neighboring cell is configured with an overlaid OFDM sequence, the UE can choose to measure the reception quality by performing correlation demodulation on an OFDM sequence within a time-domain symbol in the frequency or time domain. If the UE does not know which specific OFDM sequence is being used, the UE may need to perform a blind search among multiple candidate sequences to obtain the correlation detection results. If the UE knows which specific OFDM sequence is being used, the UE can directly obtain the correlation detection results for that OFDM sequence without needing to perform a blind search among multiple candidate sequences.

[0321] Optionally, the power information includes the offset of the LP-SS / LP WUS transmit power of a neighboring cell relative to a set reference power. The set reference power may be the transmit power of the SSB of a neighboring cell.

[0322] Optionally, LP-SS multi-beam information includes the number of LP-SS beams to be measured in neighboring cells. The UE can determine the signal reception quality of a neighboring cell based on the best-performing LP-SS beam in the neighboring cell, or it can determine the signal reception quality of a neighboring cell based on the measurement results of multiple LP-SS beams in the neighboring cell. For example, the UE can determine the signal reception quality of a neighboring cell by averaging the measurement results of multiple LP-SS beams in the neighboring cell; it can also determine the signal reception quality of a neighboring cell by using the non-uniform filtering value of the measurement results of multiple LP-SS beams in the neighboring cell.

[0323] In step S6102, the base station broadcasts the relevant parameters for cell reselection based on LP-SS to the UE through system information.

[0324] In some embodiments, the parameters related to cell reselection include at least one of the following:

[0325] (a) LP-SS reception quality threshold for serving cell.

[0326] In some embodiments, when the reception quality of the serving cell LP-SS is less than the reception quality threshold of the serving cell LP-SS, the terminal performs cell reselection based on the reception quality of neighboring cells.

[0327] In some embodiments, when the reception quality of the serving cell LP-SS is greater than or equal to the reception quality threshold of the serving cell LP-SS, cell reselection is not performed, and neighboring cells are not measured.

[0328] (b) Threshold for LP-SS reception quality in neighboring cells.

[0329] (c) The allowable gap range with the neighboring cell with the best measurement result. Among the LP-SS measurement results of multiple neighboring cells, the neighboring cells whose measurement values ​​differ from those of the neighboring cell with the best measurement result within the allowable gap range can be considered as candidate cells.

[0330] In step S6103, the terminal performs cell reselection.

[0331] (1) Step (b) in step S6102 above can be used as the basis for determining candidate neighboring cells. For example, only if the measurement quality of the LP-SS beam of a neighboring cell meets the threshold value can it be used as a candidate stationing cell. Then, the cell with the best measurement quality is selected from the candidate neighboring cells as the stationing cell.

[0332] (2) Steps (b) and (c) in step S6102 above can be used as the basis for determining candidate neighbor cells. For example, only neighbor cells whose LP-SS measurement quality is within the allowable range of the difference between the measurement value of the neighbor cell with the best measured reception quality and the measurement quality of the LP-SS beam meets the threshold value can be used as candidate neighbor cells. From these neighbor cells, the cell with the most LP-SS beams exceeding the threshold is selected as the camping cell. If multiple cells have the same maximum number of beams exceeding the threshold, the neighbor cell with the best measured reception quality can be selected as the camping cell.

[0333] (3) For neighboring cells with the same measured LP-SS reception quality, the UE prefers the neighboring cell with the smaller power offset value as the camping cell. This is because, under the condition of the same LP-SS reception quality, a smaller power offset value proves that the neighboring cell has a larger SSB power, and therefore is more suitable as the camping cell for MR.

[0334] If there is a high-priority neighboring cell in the frequency band supported by the LR, and the measured reception quality of the high-priority neighboring cell meets the threshold value in step S6102 above, then the LR will select the high-priority neighboring cell as the camping cell. If there are multiple high-priority neighboring cells that meet the threshold, the LR can refer to the methods in steps (a), (b), and (c) of S6103 to determine the camping cell.

[0335] In some embodiments, the UE uses the LR to measure the LP-SS of neighboring cells within the frequency band supported by its LR, and obtains the measurement results of the receiving quality of the neighboring cells. If the measurement results of all neighboring cells measured by the LR are lower than the above-mentioned receiving quality threshold, the UE will enable MR to perform neighboring cell measurement and cell reselection. If at least one neighboring cell among the neighboring cells measured by the LR can be used as a candidate cell, the UE will not need to enable MR and can directly select a neighboring cell as the cell to be camped according to the method described in step S6102 above.

[0336] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods.

In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated.

All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
