[0001] Cross-referencing

[0002] This disclosure claims priority to international application PCT / IB2021 / 000217 filed on 23 March 2021, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communication systems, and more specifically, to an apparatus and method for wireless communication that can provide good communication performance and / or high reliability. Background Technology

[0004] In unlicensed frequency bands, unlicensed spectrum is shared spectrum. Communication equipment in different communication systems can use unlicensed spectrum, as long as the unlicensed spectrum meets the regulatory requirements of each country or region regarding spectrum allocation. There is no need to apply for a proprietary spectrum license from the government.

[0005] To allow various communication systems using unlicensed spectrum to coexist amicably in the spectrum, some countries or regions have stipulated regulatory requirements that must be met when using unlicensed spectrum. For example, communication devices must follow a Listen-Before-Speak (LBT) or channel access procedure, meaning that the communication device must perform channel sensing before transmitting a signal on the channel. When the LBT result indicates that the channel is idle, the communication device can perform signal transmission; otherwise, the communication device cannot perform signal transmission. To ensure fairness, once a communication device successfully occupies the channel, the transmission duration cannot exceed the Maximum Channel Occupancy Time (MCOT). The LBT mechanism is also known as the channel access procedure. In New Radio (Release 16), different types of channel access procedures exist, such as Type 1, Type 2A, Type 2B, and Type 2C channel access procedures described in TS 37.213.

[0006] In NR version 16, the operating frequency range is limited to below 52.6 GHz. To further improve data throughput, future networks could potentially use higher frequency ranges, such as above 52.6 GHz. However, in some regions, frequencies above 52.6 GHz (e.g., 60 GHz) are shared spectrum. Furthermore, power spectral density is limited in this band. In such cases, the robustness or coverage of new radio (PUCCH) transmissions will be correspondingly limited. Additionally, NR version 16 introduces a span framework to limit the user equipment (UE) physical downlink control channel (PDCCH) monitoring capabilities. The current span distance is insufficient for the UE to complete the processing required for PDCCH monitoring.

[0007] Therefore, there is a need for an apparatus and method for PDCCH monitoring that can solve the problems in the prior art. Summary of the Invention

[0036] Embodiments of this disclosure are described in detail below with reference to the accompanying drawings, regarding their technical problems, structural features, objectives, and effects. Specifically, the terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the disclosure.

[0037] For uplink transmissions in shared spectrum, the UE may perform a channel access procedure before transmitting one or more uplink transmissions in the channel. The channel access procedure includes Type 1 channel access according to Section 4.2.1.1 of TS 37.213, or Type 2A channel access according to Section 4.2.1.2.1 of TS 37.213, or Type 2B channel access according to Section 4.2.1.2.2 of TS 37.213, or Type 2C channel access according to Section 4.2.1.2.3 of TS 37.213.

[0038] Figure 1 An example of three span combinations is shown. In New Radio (NR) version 16, a span framework was introduced to define the User Equipment (UE) Physical Downlink Control Channel (PDCCH) monitoring capabilities. In the example, the span combination is defined by two parameters, X and Y, where X is the distance between two consecutive spans, and Y is the span length. In NR 16, the possible span combinations are {X, Y} = {(2, 2), (4, 3), (7, 3)}. For these three span combinations, the unit is symbols. Figure 1 Three examples of span combinations are given.

[0039] The UE PDCCH monitoring capability is defined within each span by a specified combination of spans. The PDCCH monitoring capability includes the number of PDCCH candidates that the UE can monitor and the number of non-overlapping control channel elements (CCEs) that the UE can perform channel estimation on. In TS 38.213 version 16, the defined PDCCH monitoring capabilities are shown in Tables 1 and 2 below.

[0042] Table 2:

[0043]

[0044] For higher carrier frequencies above 52.6 GHz, the subcarrier spacing increases to 120 kHz, 480 kHz, and 960 kHz, resulting in a significant reduction in symbol duration compared to NR versions 15 and 16. In this case, the span distance (e.g., X = 2 symbols, X = 4 symbols, or X = 7 symbols) may be insufficient for the UE to complete the processing for PDCCH monitoring. To address this issue, in some embodiments of this disclosure, the span design needs to be modified to allow the UE to have extended processing time. Therefore, in some embodiments of this disclosure, the span parameters X and Y need to be adapted to support higher SCS conditions.

[0059] Example 1:

[0060] Figure 5 An embodiment according to this disclosure is shown in which, for SCS = 480 kHz, the first parameter X of the span combination may include four time slots corresponding to the duration of one time slot for 120 kHz. Figure 6 An embodiment according to this disclosure is shown in which, for SCS = 480 kHz, the first parameter X of the span combination may include eight time slots corresponding to the duration of two time slots for 120 kHz. Figure 7 An embodiment according to this disclosure is shown, in which, for SCS = 480 kHz, the first parameter X of the span combination may include two time slots corresponding to half a time slot duration for 120 kHz. Figures 5 to 7 In some embodiments, for the span combination {X, Y}, the value of the first parameter X represents an integer number of time slots. This number is selected based on the time slot duration corresponding to a 120 kHz subcarrier spacing (SCS). As an example, for SCS = 480 kHz, X could include four time slots corresponding to one time slot duration for 120 kHz (e.g., ...). Figure 5 (as shown), or X may include eight time slots corresponding to the duration of two time slots for 120 kHz (as shown). Figure 6(As shown) By extending the value of X, the span distance can remain substantially equivalent to the distance required by the version 16 UE, without requiring a more enhanced or advanced receiver design. Optionally, to support low-latency services, the UE PDCCH can be designed with higher capabilities; for example, X can include two time slots corresponding to half a time slot duration for 120kHz (e.g., Figure 7 (As shown).

[0061] In some embodiments, for a 480 kHz SCS, the value of X can be an integer number of symbols. This number is selected based on the slot duration corresponding to a 120 kHz subcarrier spacing (SCS). For example, X could be 56 symbols corresponding to one slot duration for 120 kHz. Alternatively, X could be 112 symbols corresponding to two slot durations for 120 kHz. Alternatively, X could be 28 symbols corresponding to half a slot duration for 120 kHz.

[0062] Figure 8 An embodiment according to this disclosure is shown in which, for SCS = 960 kHz, the first parameter X of the span combination may include eight time slots corresponding to the duration of one time slot for 120 kHz. Figure 9 An embodiment according to this disclosure is shown, in which, for SCS = 960 kHz, the first parameter X of the span combination may include 16 time slots corresponding to the duration of two time slots for 120 kHz. Figure 10 An embodiment according to this disclosure is shown in which, for SCS = 960 kHz, the first parameter X of the span combination may include four time slots corresponding to a half-slot duration for 120 kHz. Figures 8 to 10 In some embodiments, X can be eight time slots corresponding to the duration of one time slot for 120 kHz (e.g., SCS = 960 kHz). Figure 8 (as shown), or X can be 16 time slots corresponding to the duration of 2 time slots for 120kHz (as shown). Figure 9 (As shown). Optionally, to support low-latency services, the UE PDCCH can be designed to have higher capabilities; for example, X may include four time slots corresponding to half a time slot duration for 120 kHz (e.g., Figure 10 (As shown).

[0063] Example 2:

[0064] Figure 11 An embodiment of the present disclosure shows that, according to this disclosure, the second parameter Y of the span combination can be a multiple of 3 symbols. Figure 12 An embodiment of the present disclosure shows that, according to this disclosure, the second parameter Y of the span combination can be half a time slot. Figure 11 and Figure 12In some embodiments, the span length is defined by a second parameter Y. The value of Y can be an integer number of symbols. As an example, the value of Y can be less than or equal to 3. This length can fit within the CORESET length, but if the network (e.g., a base station) configures multiple search spaces in a time slot, the network needs to ensure that the search spaces fit within the span length of Y. Therefore, if the span length is short, many search spaces can overlap in the time domain, which can lead to some blocking problems. To overcome this problem, alternatively, the value of Y can be a multiple of 3 symbols, such as 6 symbols, 9 symbols, or 12 symbols (e.g., ...). Figure 11 (As shown). Optionally, the value of Y can be in units of time slots. As an example, the value of Y is 1 time slot. Optionally, the value of Y is greater than 1 time slot. Optionally, the value of Y is half a time slot (e.g., Figure 12 (As shown).

[0065] In some embodiments, when defining the values ​​of X and Y, the span combination for carrier frequencies above 52.6 GHz can be determined based on {X, Y}. It should be noted that, as presented in the examples above, the values ​​of X and Y can be defined according to the SCS value, for example, SCS = 120 kHz, 480 kHz, or 960 kHz.

[0066] Example 3:

[0067] In the previous example, a span combination {X, Y} was proposed, where for SCS = 480kHz, X can be at least one of the following: 2 time slots, 4 time slots, or 8 time slots. Y can be at least one of the following: 2 symbols, 3 symbols, 6 symbols, 9 symbols, 12 symbols, 0.5 time slots (7 symbols), 1 time slot, or 2 time slots. For SCS = 960kHz, X can be at least one of the following: 4 time slots, 8 time slots, or 16 time slots. Y can be at least one of the following: 2 symbols, 3 symbols, 6 symbols, 9 symbols, 12 symbols, 0.5 time slots (7 symbols), 1 time slot, or 2 time slots.

[0068] In some embodiments, the UE PDCCH monitoring capability is defined for a given span combination. The PDCCH monitoring capability is defined in terms of the number of PDCCH candidates and the number of non-overlapping CCEs for each span combination. In some examples, the PDCCH monitoring capability depends on the value of X, that is, for a given X, the PDCCH monitoring capability is the same for different values ​​of Y.

[0069] For SCS = 480kHz:

[0070] 2 time slots 10 and / or 12 4 time slots 20 8 time slots 40 and / or 20

[0071] 2 time slots 16 and / or 18 4 time slots 32 8 time slots 64 and / or 32

[0072] For SCS = 960kHz:

[0073]

[0074]

[0075] 4 time slots 16 and / or 18 8 time slots 32 16 time slots 64 and / or 32

[0076] In some examples, PDCCH monitoring capability depends on both X and Y. In this case, there may exist a threshold T such that, for a given X, there is one PDCCH monitoring capability when Y≤T, and another PDCCH monitoring capability when Y>T. For example, the value of T can be three symbols or half a time slot.

[0077] For SCS = 480kHz:

[0078] 2 time slots 10 and / or 12 4 time slots 20 8 time slots 40 and / or 20

[0079] 2 time slots 16 and / or 18 4 time slots 32 8 time slots 64 and / or 32

[0080] 2 time slots 20 4 time slots 40 8 time slots 80

[0081] 2 time slots 32 4 time slots 64 8 time slots 128

[0082] For SCS = 960kHz:

[0083] 4 time slots 10 and / or 12 8 time slots 20 16 time slots 40 and / or 20

[0084] 4 time slots 16 and / or 18 8 time slots 32 16 time slots 64 and / or 32

[0085] 4 time slots 20 8 time slots 40 16 time slots 80

[0086] 4 time slots 32 8 time slots 64 16 time slots 128

[0087] Example 4:

[0088] Figure 13 The illustration shows an embodiment of the present disclosure in which the base station configures PDCCH timings during a duration of Y. The UE needs to determine the span from a set of span combinations presented in the example above. The UE determines this based on the configured PDCCH monitoring timings. When the span is in symbols, the UE determines the span such that it begins at the first symbol of the PDCCH monitoring timing and ends at the last symbol of the PDCCH monitoring timing. For example, as... Figure 13As shown, if the span combination has a value of Y of 3 symbols, the base station (e.g., gNB) needs to configure the PDCCH timing within the duration of Y. If the PDCCH monitoring occasion (MO) starts at symbol 0 and ends at symbol 1, the UE determines that the span length is 2 symbols.

[0089] Figure 14 An embodiment according to this disclosure is shown, in which the span can span time slots. In some examples, the span must be defined or determined within a time slot. Optionally, the span can span time slots, and / or the span can be determined within a group of time slots, wherein the group of time slots includes more than one time slot, such as... Figure 14 As shown.

[0090] Figure 15 The timing of PDCCH monitoring according to an embodiment of this disclosure is illustrated. Figure 15 In some examples, the span unit is a time slot, and the UE determines the span such that the span begins at the time slot where the first symbol is located and ends at the time slot where the last symbol is located, where the PDCCH monitoring timing begins at the first symbol and ends at the last symbol, and the number of time slots of the span reaches Y.

[0091] Example 5:

[0092] Figure 16 The PDCCH monitoring timing and span combinations according to embodiments of this disclosure are illustrated. In some examples, the UE reports supported span combinations, i.e., supported {X, Y}, to the network. The network then configures the PDCCH monitoring timing based on the span combinations supported by the UE. From the UE's perspective, once the PDCCH monitoring timing is configured, the UE determines the appropriate span combination for the configured PDCCH MO. The UE then uses the PDCCH monitoring capabilities corresponding to the determined span combination to monitor the PDCCH. Figure 16 As shown, assume the UE reports to the network that it supports two {X, Y} span combinations: {X = 4 time slots, Y = 3 symbols} and {X = 2 time slots, Y = 3 symbols}. Then, after network configuration regarding PDCCH monitoring timing, the UE determines the appropriate span combination for the PDCCH MO. In our example, since the MO can be covered by both span combinations, the UE will use the span combination that provides the maximum number of PDCCH candidates and CCEs for PDCCH monitoring.

[0093] Some embodiments offer the following commercial benefits: 1. Solving problems in the prior art. 2. Improving span design to support higher subcarrier spacing (SCS) scenarios. 3. Providing span distance to enable the UE to complete processing for Physical Downlink Control Channel (PDCCH) monitoring. 4. Providing good communication performance. 5.
