Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and more specifically, to a method for optimizing blind detection capability, an apparatus for optimizing blind detection capability, an electronic device, and a computer-readable storage medium. Background Technology

[0002] During communication between a terminal and a base station, the terminal can perform blind detection on the Physical Downlink Control Channel (PDCCH) to obtain Downlink Control Information (DCI) sent by the base station. In related technologies, the terminal's blind detection capability is limited to each time slot, but this configuration has some problems.

[0003] Specifically, the terminal and base station primarily communicate in frequency bands below 52.6 GHz. In this case, the subcarrier spacing (SCS) can be 15 kHz, 30 kHz, 60 kHz, or 120 kHz, and the length of a time slot in the time domain is related to the subcarrier spacing. For example, with a subcarrier spacing of 15 kHz, a time slot is 1 ms; with a subcarrier spacing of 30 kHz, a time slot is 0.5 ms; and with a subcarrier spacing of 60 kHz, a time slot is 0.25 ms. That is, the larger the subcarrier spacing, the shorter the time slot in the time domain.

[0004] However, with the expansion of frequency bands, terminals and base stations also need to communicate in frequency bands above 60GHz. In high-frequency bands, in order to cope with phase noise, it is necessary to increase the subcarrier spacing, for example, the subcarrier spacing is 960kHz. In this case, a time slot is 0.015625ms, or 1 / 64ms.

[0005] It is evident that in high-frequency communication, the length of a time slot is much less than 1 ms. However, the processing power of the terminal is limited. With extremely short time slots, it may be difficult to schedule the Physical Uplink Shared Channel (PUSCH) / Physical Downlink Shared Channel (PDSCH) based on downlink control information in every time slot. Therefore, in this situation, the base station may not need to configure a Physical Downlink Control Channel carrying downlink control information in every time slot. However, if the terminal's blind detection capability is limited to each time slot, this capability must be distributed across all time slots. This prevents the terminal from concentrating its blind detection capability solely on the time slots configured with the Physical Downlink Control Channel, thus wasting the terminal's computing resources. Summary of the Invention

[0018] Optionally, the second subcarrier spacing is one of the following: 15KHz, 30KHz, 60KHz, or 120KHz.

[0019] Optionally, the apparatus further includes: an information receiving module configured to receive resource information of the physical downlink control channel sent by the base station; a time slot determination module configured to determine the target time slot of the physical downlink control channel in the n time slots based on the resource information; and an information determination module configured to blindly detect downlink control information in the physical downlink control channel of the target time slot based on the blind detection capability information.

[0020] Optionally, the resource information includes a control resource set and a search space.

Then, a maximum of 16 physical downlink control channel candidates can be detected in the target time slots, and the maximum number of non-overlapping control channel elements is 20. Accordingly, the blind detection capability is not easily wasted, and the number of physical downlink control channel candidates detected in the target time slots is sufficient, which is beneficial for detecting physical downlink control channels carrying downlink control information.

[0031] Figure 7 This is a schematic block diagram illustrating an apparatus for optimizing blind detection capabilities according to embodiments of the present disclosure. Detailed Implementation

[0032] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0033] Figure 1 This is a schematic flowchart illustrating a blind detection capability optimization method according to an embodiment of the present disclosure. The method shown in this embodiment can be applied to a terminal, which can communicate with a base station as a user equipment. The base station can be a 5G base station, and the terminal includes, but is not limited to, electronic devices such as mobile phones, tablets, wearable devices, sensors, and IoT devices.

[0034] like Figure 1As shown, the method for optimizing blind detection capability may include the following steps:

[0035] In step S101, blind detection capability information is determined, wherein the blind detection capability information includes the maximum number of physical downlink control channel candidates detected in every n time slots under the first subcarrier spacing, and / or the maximum number of non-overlapping control channel elements in every n time slots under the first subcarrier spacing, where n is an integer greater than 1.

[0036] It should be noted that the maximum number of non-overlapping control channel elements in every n time slots under the first subcarrier interval, specifically for the terminal, can be the maximum number of non-overlapping control channel elements that can be blindly detected in every n time slots under the first subcarrier interval.

[0037] In one embodiment, the blind detection capability information determined by the terminal may be pre-stored in the terminal, for example, in information pre-defined in the communication protocol between the terminal and the base station.

[0038] The blind detection capability information can mainly include two aspects: one is the maximum number of physical downlink control channel candidates detected in every n time slots under the first subcarrier interval, and the other is the maximum number of non-overlapping control channel units in every n time slots under the first subcarrier interval, where n is an integer greater than 1.

[0039] In related technologies, the maximum number of physical downlink control channel candidates detected in each time slot can be as follows: Figure 2A As shown. The maximum number of non-overlapping control channel elements in each time slot can be as follows: Figure 2B As shown.

[0040] In one embodiment, the maximum number of physical downlink control channel candidates detected per n time slots under the first subcarrier interval can be as follows: Figure 3A As shown, the data is stored in the terminal in tabular form. The maximum number of non-overlapping control channel elements per n time slot under the first subcarrier interval can be as follows: Figure 3B As shown, it is stored in the terminal in the form of a table.

[0041] like Figure 2A and Figure 2B As shown, in related technologies, the terminal's blind detection capability information is limited to each time slot, for example, in... Figure 2A In this case, with μ=0, the subcarrier spacing is 15kHz, the maximum number of physical downlink control channel candidates detected per time slot is 44, and the maximum number of non-overlapping control channel elements per time slot is 56.

[0042] Figure 3A and Figure 3BOnly cases where μ is 4, 5, or 6, i.e., subcarrier spacing of 240kHz, 480kHz, and 960kHz, are shown. Cases where μ is 0, 1, 2, or 3 can be configured as needed. Figure 3A The specific values ​​A1, A2, and A3, and Figure 3B The specific values ​​B1, B2, and B3 can be set according to the actual situation.

[0043] For different subcarrier spacings, n can be different or the same; for different subcarrier spacings, the maximum number of physical downlink control channel candidates detected in every n time slots can be different or the same; for different subcarrier spacings, the maximum number of non-overlapping control channel elements in every n time slots can be different or the same.

[0044] Taking n=4 as an example, with a subcarrier spacing of 960kHz, the maximum number of physical downlink control channel candidates detected per 4 time slots is 16, and the maximum number of non-overlapping control channel elements per 4 time slots is 20. In related technologies, since the terminal's blind detection capability is configured for each time slot, if the terminal's blind detection capability is the same as the above embodiment described in this application, with a subcarrier spacing of 960kHz, then the maximum number of physical downlink control channel candidates detected per time slot is 4, and the maximum number of non-overlapping control channel elements per time slot is 5.

[0045] For example, based on the resource information of the physical downlink control channel sent by the base station, the terminal determines that the base station has configured the physical downlink control channel in the target time slot of the four time slots.

[0046] Based on the blind detection capability in related technologies, the terminal can only detect a maximum of 4 physical downlink control channel candidates in the target time slot, and the maximum number of non-overlapping control channel elements is 5. Since the blind detection capability is configured for each time slot, some blind detection capability is scattered in time slots without configured physical downlink control channels, wasting blind detection capability. Furthermore, the number of physical downlink control channel candidates detected in the target time slot is too small, causing the base station to only be able to select time-frequency resources for carrying scheduling DCI in very limited time-frequency resource locations, making it difficult to achieve time-frequency domain diversity gain. Moreover, when other DCIs are also waiting to be transmitted, it is very easy to cause PDCCH congestion.

[0047] According to the embodiments of this disclosure, since the blind detection capability is configured for every n time slots, the terminal can flexibly apply the blind detection capability in the n time slots according to the actual situation. Therefore, when it is determined that the base station has configured physical downlink control channels in the target time slots out of four time slots, all blind detection capabilities can be applied to the target time slots. Thus, a maximum of 16 physical downlink control channel candidates can be detected in the target time slots, and the maximum number of non-overlapping control channel elements is 20. Accordingly, blind detection capability is not easily wasted, and the number of physical downlink control channel candidates detected in the target time slots is sufficiently large, which is beneficial for obtaining time-frequency diversity gain and reducing the probability of DCI blocking.

[0048] It should be noted that the number of target time slots can be less than n or equal to n, and can be determined based on the resource information of the physical downlink control channel configured by the base station.

[0049] Optionally, the first subcarrier spacing is greater than 120 kHz.

[0050] Optionally, the first subcarrier spacing is one of the following: 240KHz, 480KHz, or 960KHz.

[0051] It should be noted that the range of the first subcarrier spacing is not limited to the three spacings of 240KHz, 480KHz, and 960KHz mentioned above. It can be adjusted as needed. For example, the first subcarrier spacing can also include spacings less than 240KHz or spacings greater than 960KHz, specifically 1920KHz, etc.

[0052] In one embodiment, when the subcarrier spacing (i.e., the first subcarrier spacing) is large, the blind detection capability information determined by the terminal is as described in the above embodiment, that is, the maximum number of physical downlink control channel candidates detected in every n time slots under the first subcarrier spacing, and / or the maximum number of non-overlapping control channel units in every n time slots under the first subcarrier spacing.

[0053] Because the time slot length is very short when the subcarrier spacing is large, the terminal's processing capacity is insufficient to schedule the physical downlink shared channel in each time slot. In this case, the base station is more likely to configure physical downlink control channel candidates in the target time slot of every n time slots. Therefore, the blind detection capability information determined by the terminal in this case can be configured for every n time slots, so that in the above embodiment, all blind detection capabilities can be applied to the target time slot.

[0054] In one embodiment, the terminal can report its processing capability to the base station, enabling the base station to determine whether to configure physical downlink control channel candidates in the target time slots every n time slots. For example, when the terminal's processing capability is weak (specifically, the amount of data that can be processed per unit time is greater than a preset value), the base station configures physical downlink control channel candidates in the target time slots every n time slots. When the terminal's processing capability is strong, the base station configures physical downlink control channel candidates in the target time slots of each time slot (specifically, the amount of data that can be processed per unit time is less than a preset value).

[0055] Optionally, the blind detection capability information further includes the maximum number of physical downlink control channel candidates detected in each time slot under the second subcarrier spacing, and / or the maximum number of non-overlapping control channel elements in each time slot under the second subcarrier spacing, wherein the second subcarrier spacing is less than the first subcarrier spacing.

[0056] Optionally, the second subcarrier spacing is one of the following: 15KHz, 30KHz, 60KHz, or 120KHz.

[0057] It should be noted that the second subcarrier interval and the first subcarrier interval in the above embodiments are both subcarrier intervals for communication between the terminal and the base station. Generally, the subcarrier interval is fixed during a single communication process. However, in different communication processes, such as when the terminal disconnects from the base station and then reconnects to the base station to communicate with it, the subcarrier interval can be different from the subcarrier interval during the previous communication.

[0058] In one embodiment, when the subcarrier spacing (i.e., the second subcarrier spacing) is small, the blind detection capability information determined by the terminal may be the maximum number of physical downlink control channel candidates detected per time slot, and / or the maximum number of non-overlapping control channel elements per time slot under the second subcarrier spacing.

[0059] Because the time slot length is relatively long when the subcarrier spacing is large, the terminal's processing capacity can easily schedule the physical downlink shared channel in each time slot. In this case, the base station is more likely to configure physical downlink control channel candidates in the target time slot of each time slot. Therefore, the blind detection capability information determined by the terminal in this case can be configured for each time slot, without the terminal needing to calculate how to allocate blind detection capability in each time slot, which helps reduce the workload of the terminal.

[0060] Figure 4 This is a schematic flowchart illustrating another blind detection capability optimization method according to embodiments of the present disclosure. Figure 4 As shown, the method further includes:

[0061] In step S102, the resource information of the physical downlink control channel sent by the base station is received; the resource information may specifically consist of time-domain resource information and frequency-domain resource information.

[0062] In step S103, the target time slot of the physical downlink control channel in the n time slots is determined based on the resource information;

[0063] In step S104, blind detection downlink control information is performed in the physical downlink control channel of the target time slot according to the blind detection capability information.

[0064] Optionally, the resource information includes a control resource set and a search space.

[0065] In one embodiment, the base station can send resource information of the physical downlink control channel to the terminal. The resource information may include a control resource set (CORESET) and a search space. Based on the resource information, the terminal can determine the target time slot of the physical downlink control channel among n time slots. Then, the terminal can blindly detect downlink control information in the physical downlink control channel of the target time slot based on the blind detection capability information.

[0066] It should be noted that the target time slot can be one time slot out of every n time slots, or it can be multiple time slots out of every n time slots. When the target time slot is multiple time slots out of every n time slots, the terminal can distribute the blind detection capability evenly among each of the multiple time slots.

[0067] For example, if n is 4 and the target time slot is the 3rd time slot out of every 4 time slots, then the terminal can apply all its blind detection capabilities to the 3rd time slot out of every 4 time slots, so that a sufficient number of physical downlink control channel candidates can be detected within the target time slot, which is beneficial for detecting the physical downlink control channel carrying downlink control information.

[0068] For example, if n is 4 and the target time slots are the 2nd and 3rd time slots out of every 4 time slots, then the terminal can distribute all blind detection capabilities equally between the 2nd and 3rd time slots, so that there is an equal probability of detecting the physical downlink control channel carrying downlink control information in both target time slots.
