[0031] The detailed description set forth below with reference to the accompanying drawings is intended as a description of exemplary embodiments of the systems and methods for UE PDC CH monitoring capability reporting provided in this disclosure, and is not intended to represent the only form in which this disclosure may be constructed or utilized. This specification illustrates features of the disclosure in conjunction with the illustrated embodiments. However, it should be understood that the same or equivalent functions and structures may be implemented through different embodiments, which are also intended to cover the scope of this disclosure. As shown elsewhere herein, the same element numbers are intended to indicate the same elements or features.

[0032] Figure 1 This is a simplified block diagram of two components of a 5G communication system in some embodiments. User equipment (UE) 105 forms a connection (e.g., a wireless connection) with network 110 (e.g., with a base station of network 110). In a 5G communication system, the physical downlink control channel (PDCCH) monitoring capability of the user equipment (UE) can be signaled from the UE to the network (e.g., to the base station (BS)), so that the network can then adopt a downlink control information (DCI) monitoring configuration for the UE within the UE's capabilities. As used herein, certain phrases such as "user equipment" and "downlink control information" (discussed in further detail below), expressed in the singular, can also be used to refer to the plural form. In 5G convention, two UE capability function groups (UE capability function groups (FG) 3-5a and UE capability function groups FG 3-5b) define possible UE capabilities regarding PDCCH monitoring.

[0033] Based on the composition description of Functional Group FG3-5b (in the technical specification identified as TS38.822 issued by the 3rd Generation Partnership Project), the UE may report one of {(7,3)}, {(4,3),(7,3)}, and {(2,2),(4,3),(7,3)} as a candidate value set {(X,Y)}, and the PDCCH monitoring configuration generated by the network is expected to comply with the reported span gap and span length limits. The span consists of consecutive symbols within a time slot (as illustrated in the 3rd Generation Partnership Project RAN1#96bis meeting), and the span pattern within a time slot is determined based on: (i) the PDCCH monitoring timing (MO) pattern, (ii) the set of one or more ordered pairs (X,Y) identified in the report sent by the UE to the network (under Functional Group FG3-5b), and (iii) the control resource set (CORESET) configuration for the user equipment (UE). Specifically, except for the last span within a time slot, which may have a shorter duration, spans within a time slot have the same duration determined by max{the maximum of all CORESET durations and the minimum of Y among the candidate values ​​reported by the UE}. The first span in the span pattern within a time slot begins with the symbol of the minimum index that configures the monitoring timing for the UE. The next span begins with the MO not included in the first span, and the same process is applied to construct subsequent spans. The interval (or “span gap”) between the corresponding starting points of any two consecutive spans within a time slot and across time slots must satisfy the same (X,Y) constraint, where X represents the minimum time interval of OFDM symbols between the corresponding starting points of the two spans, and Y represents the maximum number of consecutive OFDM symbols in each span. The UE may (e.g., according to version 15 of the 5G standard) report its monitoring capabilities from three possible sets {(7,3)}, {(4,3),(7,3)}, and {(2,2),(4,3),(7,3)}.

[0034] Another PDCCH monitoring capability, as described in FG3-5a, constrains symbol-based gaps between two downlink (DL) unicast DCIs, between two uplink (UL) unicast DCIs, or between DL unicast DCIs and UL unicast DCIs at different monitoring times. Therefore, under FG3-5a, the UE may (i) not report the capability, (ii) report the need for a "gap constraint" (i.e., a "gap constraint" to be handled by the UE), requiring consecutive DCIs to be separated by a minimum number of symbols (the required number of symbols depends on the subcarrier spacing (SCS) as defined in TS38.822), or (iii) report that no gap constraint is required.

[0035] When a UE reports its PDCCH monitoring capability within FG3-5a, the network is expected to adhere to the reported gap constraints when sending DCIs to the UE. Similarly, when a UE reports its PDCCH monitoring capability within FG3-5b, the MO patterns generated by the network and sent to the UE are expected to adhere to the reported span constraints.

[0036] In some embodiments, the UE may (i) report its capabilities within FG3-5a (reporting a minimum time interval, wherein the minimum time interval requirement specifies a minimum time interval (or “gap”) between DCIs), and (ii) report its capabilities within FG3-5b (reporting a span pattern requirement, wherein the span pattern requirement specifies one or more restrictions on length and gap), and the network may choose to comply with one or the other, or both. As used herein, reporting capabilities within FG3-5a (whether the reported capability is (i) without a “gap restriction” (i.e., no minimum time interval is required between DCIs) or (ii) with a gap restriction (i.e., the minimum time interval must be (a) 2 OFDM symbols at 15 kHz, (b) 4 OFDM symbols at 30 kHz, (c) 7 OFDM symbols at 60 kHz using NCP, or (d) 11 OFDM symbols at 120 kHz)) is an example of reporting a minimum time interval requirement, wherein the minimum time interval requirement specifies a minimum time interval between downlink control information (DCIs). As used in this article, the reporting of capabilities within FG3-5b is an example of reporting span pattern requirements.

[0037] Dual reporting (i.e., the UE reporting its capabilities under both FG3-5a and FG3-5b) can lead to (i) greater network flexibility in scheduling MO and DCI, (ii) improved performance, and (iii) better utilization of the UE's capabilities, as shown in the following example (assuming the UE reports its capabilities under FG3-5b with {(2,2),(4,3),(7,3)} and the UE reports its capabilities under FG3-5a with DCI gap restrictions).

[0038] Figure 2A This illustrates a configuration with a subcarrier spacing (SCS) of 15 kHz, using frequency division duplex (FDD), and a CORESET duration of 3 symbols. In this configuration, each span consists of 3 symbols, and the span gap between any two spans is at least 4 symbols. Furthermore, because the UE reports gap limitations under FG3-5a, it is expected that the network will allow a gap of at least 2 symbols between any two DCIs (2 symbols is the gap specified by TS38.822 when the UE reports gap limitations under FG3-5a and the SCS is 15 kHz). Therefore, Figure 2AThe MO configuration in FG3-5b is valid in terms of span restrictions, and DCI transmission is valid in terms of DCI gap restrictions in FG3-5a. However, DCI transmission violates FG3-5b, which requires that each span can only contain one downlink (DL) DCI. In other words, if the UE only reports PDCCH monitoring capability under FG3-5b (but not under FG3-5a), the network will not be able to send... Figure 2A The DCI shown.

[0039] As another example, Figure 2B The diagram illustrates a configuration with SCS = 30kHz, using Frequency Division Duplex (FDD), and a CORESET duration of 2 symbols. In this configuration, each span consists of 2 symbols, and the span gap between any two spans is at least 2 symbols. Furthermore, because the UE reports gap limitations under FG3-5a, it is expected that the network will allow a gap of at least 4 symbols between any two DCIs (4 symbols is the gap specified by TS38.822 when the UE reports gap limitations under FG3-5a and SCS is 30kHz). Therefore, Figure 2B The MO configuration in the code is effective in terms of span limitations in FG3-5b, and DCI transmission is effective in terms of the number of DCIs within a span based on FG3-5b. However, DCI transmission violates FG3-5a, where, under FG3-5a, the network is expected to provide a 4-symbol span gap between any two DCIs. In other words, if the UE only reports PDCCH monitoring capability under FG3-5a (and not under FG3-5b), the network will not be able to transmit. Figure 2B The DCI shown.

[0040] If the UE reports capabilities under both FG3-5a and FG3-5b, and if, as described above, the network can choose to comply with one or the other, or comply with both, then in Figure 2A and Figure 2B In each of the examples, the network is able to make selection possible, enabling the illustrated transmission. Figure 2A In this case, the network can choose to comply with the reporting capability under FG3-5a, enabling Figure 2A The transmissions shown are permitted, and... Figure 2B In this case, the network can choose to comply with the reporting capability under FG3-5b, enabling Figure 2B The transmission shown is permitted. Figure 2C The table in the document summarizes these observations. As shown in the table, the above text addresses... Figure 2A (Reported only under FG3-5b) and Figure 2B(Reported only under FG3-5a) The single-report scenario described does not make the individual transmissions shown permissible; however, (under both FG3-5a and FG3-5b, the UE's PDCCH monitoring capability) dual-reporting results in... Figure 2A and Figure 2B The two types of transmissions shown are permitted.

[0041] In a system that implements (dual) reporting capability for PDCCH monitoring under both FG3-5a and FG3-5b, the following scenario may occur: At the first moment when the UE connects to the network and reports its capability under both FG3-5a and FG3-5b, the network chooses to comply with the span mode requirement (of FG3-5b) but not the minimum time interval requirement (of FG3-5a), and the network may send the UE (i) a first monitoring moment (MO) mode that complies with the span mode requirement, and (ii) two DCIs separated by an interval smaller than the minimum time interval. Then, at the second moment when the UE connects to the network, the network chooses not to comply with the span mode requirement (of FG3-5b) but complies with the minimum time interval requirement (of FG3-5a), and the network may send the UE a second monitoring moment (MO) mode that does not comply with the span mode requirement.

[0042] Similarly, it could be that when a first UE connects to the network and reports its capabilities under both FG3-5a and FG3-5b, the network chooses to comply with the span mode requirement (of FG3-5b) but not the minimum time interval requirement (of FG3-5a), and when a second UE connects to the network and reports the same PDCCH monitoring capabilities as reported by the first UE, the network chooses not to comply with the span mode requirement (of FG3-5b) but to comply with the minimum time interval requirement (of FG3-5a) in its interactions with the second UE.

[0043] When a UE reports its PDCCH monitoring capabilities under both FG3-5a and FG3-5b, it may be advantageous for the UE to infer from the network's behavior whether the network has chosen to comply with the capability reported under FG3-5a or FG3-5b. This allows the UE to exclude certain symbols (e.g., any symbol immediately following a symbol with DCI) from potentially containing DCI if the capability reported under FG3-5a is a gap constraint specifying that DCI is not present in the symbol immediately following the symbol with DCI, and the UE can disable DCI reception during those symbols, for example, to save power.

[0044] like Figure 3As shown, at 305, the UE reports its PDCCH monitoring capabilities under both FG3-5a and FG3-5b, and at 310, the UE receives the PDCCH monitoring configuration from the network. At 315, the UE determines whether the PDCCH monitoring configuration complies with the capabilities reported by the UE under FG3-5b; if it does not comply with the capabilities reported by the UE under FG3-5b, then at 320, the UE infers that the network has chosen to comply with the PDCCH monitoring capabilities reported by the UE under FG3-5a, and the UE detects DCI accordingly. If the PDCCH monitoring capabilities reported by the UE under FG3-5a are gap-limited, this may involve immediately disabling DCI reception after receiving DCI.

[0045] If the UE determines at 315 that the PDCCH monitoring configuration complies with the UE's reporting capability under FG3-5b, the UE may not be able to determine, based on the PDCCH monitoring configuration received from the network, whether (i) the network has chosen to comply only with the UE's reporting capability under FG3-5b or (ii) the network has chosen to comply with the UE's reporting capability under both FG3-5a and FG3-5b. However, if the network sends and the UE receives (at 325) a selection notification informing the UE which capability(s) the network has chosen to comply with, the UE may monitor the DCI accordingly at 330 or 335. This selection notification may be explicit, for example, a specific signal sent by the network to the UE, or it may be implicit, for example, another configuration setting used by the network, from which the UE can infer the selection made by the network.

[0046] In some embodiments, the network includes a first processing circuit (e.g., one or more CPUs), and the UE includes the processing circuit. The processing circuit can perform some or all of the methods described herein, such as transmitting and receiving configuration information, capability information, and DCI (via suitable transmitting and receiving hardware, such as radio, microwave, or millimeter-wave transmitters and receivers, some of which may be external to the processing circuit). The term "processing circuit" is used herein to mean any combination of hardware, firmware, and software for processing data or digital signals. Processing circuit hardware may include, for example, application-specific integrated circuits (ASICs), general-purpose or dedicated central processing units (CPUs), digital signal processors (DSPs), graphics processing units (GPUs), and programmable logic devices (such as field-programmable gate arrays FPGAs). In the processing circuit, as used herein, each function is performed by hardware configured (i.e., hardwired) to perform said function, or by more general-purpose hardware (such as a CPU) configured to execute instructions stored in a non-transitory storage medium. The processing circuit may be fabricated on a single printed circuit board (PCB) or distributed across several interconnected PCBs. The processing circuit may include other processing circuits; for example, the processing circuit may include two processing circuits, an FPGA and a CPU, interconnected on a PCB.

[0047] As used herein, “a part” of something means “at least some” of that thing, and therefore can mean less than or all of that thing. Thus, “a part” of something includes the whole thing as a special case, that is, an example where the whole thing is a part of something. As used herein, the word “or” is inclusive, such that, for example, “A or B” means any one of the following: (i) A, (ii) B, and (iii) A and B.

[0048] As used herein, when a method (e.g., adjustment) or a first quantity (e.g., a first variable) is referred to as “based on” a second quantity (e.g., a second variable), it means that the second quantity is an input to the method or affects the first quantity. For example, the second quantity may be an input to a function that computes the first quantity (e.g., a unique input or one of several inputs), or the first quantity may be equal to the second quantity, or the first quantity may be the same as the second variable (e.g., stored in the same one or more locations in memory).

[0049] It will be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or portions, these elements, components, regions, layers, and / or portions should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or portion from another element, component, region, layer, or portion. Therefore, without departing from the spirit and scope of the inventive concept, the first element, component, region, layer, or portion discussed herein may be referred to as the second element, component, region, layer, or portion.

[0050] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the inventive concept. As used herein, the terms “substantially,” “about,” and similar terms are used as approximate terms rather than terms of degree and are intended to explain the inherent biases of measured or calculated values ​​that will be recognized by one of ordinary skill in the art.

[0051] As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. It will be further understood that, when used in this specification, the terms “comprising” and / or “including” specify the presence of the stated features, integers, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof. As used herein, the terms “and / or” include any and all combinations of one or more of the associated listed items. Expressions such as “at least one of…” modify the entire list of elements when preceding it, without modifying any individual element in the list. Furthermore, when describing embodiments of the inventive concept, the use of “may” refers to “one or more embodiments of this disclosure.” Additionally, the term “exemplary” is intended to refer to an example or illustration. As used herein, the term “use” may be considered synonymous with the term “utilize.”

[0052] It will be understood that when an element or layer is referred to as being "on," "connected to," "coupled to," or "adjacent to" another element or layer, the element or layer may be directly on, directly connected to, directly coupled to, or directly adjacent to the other element or layer, or one or more intermediate elements or layers may be present. In contrast, when an element or layer is referred to as being "directly on," "directly connected to," "directly coupled to," or "immediately adjacent to" another element or layer, no intermediate elements or layers are present.

[0053] Any numerical range described herein is intended to include all subranges containing the same numerical precision within the listed ranges. For example, the range “1.0 to 10.0” or “between 1.0 and 10.0” is intended to include all subranges between the listed minimum value 1.0 and the listed maximum value 10.0 (and includes both the listed minimum value 1.0 and the listed maximum value 10.0), i.e., a minimum value equal to or greater than 1.0 and a maximum value equal to or less than 10.0, such as 2.4 to 7.6. Any maximum numerical limit listed herein is intended to include all lower numerical limits contained therein, and any minimum numerical limit described in this specification is intended to include all higher numerical limits contained therein.

[0054] Although exemplary embodiments of systems and methods for UE PDCCH monitoring capability reporting have been specifically described and illustrated herein, many modifications and variations will be apparent to those skilled in the art. Therefore, it should be understood that systems and methods for UE PDCCH monitoring capability reporting constructed in accordance with the principles of this disclosure may be implemented differently than those specifically described herein. The invention is also defined in the appended claims and their equivalents.
