Abstract

Some aspects of the present disclosure include apparatuses and methods for implementing mechanisms for downlink control information between an electronic device (e.g., UE) and a network for cell detection and measurement. For example, some aspects relate to an electronic device including a transceiver and a processor communicatively coupled to the transceiver. The processor monitors one or more paging occasions within a discontinuous reception cycle (DRX) and may determine not to monitor one or more paging occasions within the DRX. Each paging occasion may include downlink control information transmitted by the network for one or more paging messages.

Description

Background Art Technical Field

[0001] The described aspects generally relate to cell detection and measurement in wireless communication. For example, aspects of the present disclosure relate to mechanisms for monitoring downlink control information between an electronic device (e.g., a user equipment (UE)) and a network. Background Art

[0003] When a user equipment (UE) connects to a base station in a cell (e.g., an evolved Node B (eNB)) via a wireless network associated with the base station for communication, the UE may monitor one or more occasions of downlink control information, such as a paging occasion. Generally, the UE monitors one paging occasion per discontinuous reception cycle. Increasing the number of paging occasions per discontinuous reception cycle may have an adverse effect on UE power consumption, such as increased power consumed by the UE's transceiver or baseband processor. In addition, the UE may receive signals in a bandwidth part (BWP) that includes multiple subbands (e.g., more than one 20 MHz subband). However, receiving signals based on listen-before-talk (LBT) may fail for some of the BWP subbands in the BWP, resulting in puncturing of the expected signal (such as downlink control information). Summary of the Invention

[0004] Some aspects of the present disclosure include apparatuses and methods for a user equipment (UE) to monitor downlink control information (such as a paging occasion). In some aspects, the UE monitors one or more paging occasions within a discontinuous reception cycle (DRX). The UE may determine not to monitor one or more paging occasions within the DRX. Each paging occasion may include downlink control information transmitted by the network for one or more paging messages. Thus, through a coordinated determination of which paging occasions to skip or stop monitoring, the UE may improve power consumption when monitoring an increased number of paging occasions within the DRX while obtaining improved latency in NR-U.

[0005] According to some aspects, the UE defines a paging inactivity timer corresponding to a value associated with the paging occasion to be monitored. Then, when performing paging occasion monitoring within a discontinuous reception cycle (DRX), determining whether not to monitor one or more given paging occasions may be based on the paging inactivity timer. The paging inactivity timer may represent a value associated with the paging occasion, such as a value of the duration or number of the monitored occasion. According to some aspects, the UE may interrupt monitoring of multiple paging occasions based on the paging inactivity timer. In some of these aspects, the UE may be configured to initialize the paging inactivity timer after receiving downlink control information that does not include an addressing indicator associated with the UE.

[0006] According to some aspects, the UE may receive an indicator from the network that includes configuration information for paging occasion monitoring behavior for the electronic device. An information element transmitted with a paging message may be used to provide the indicator, and the information element may indicate whether additional paging occasions should be monitored.

[0007] According to some aspects, the UE may receive the indicator using higher layer signaling such as radio resource control (RRC) layer signaling. In some aspects, the indicator may represent an instruction for the electronic device to interrupt paging occasion monitoring within DRX based on detecting a transmission by a base station (BS) and determining that a paging identifier message transmitted by the BS does not include an address associated with the electronic device. Some aspects include the UE detecting a transmission by the base station of a demodulation reference signal (DMRS).

[0008] According to additional aspects, the UE may receive a control resource set (CORESET) configuration that defines a mapping of physical resources in a bandwidth part (BWP). The BWP includes a plurality of subbands. The UE may configure a basic CORESET (B-CORESET) within a single subband of the plurality of subbands. The UE may then replicate the B-CORESET in one or more virtual CORESETS (V-CORESETS). Each V-CORESET of the one or more V-CORESETS may be replicated in a corresponding one or more subbands in other subbands of the BWP. The UE may configure a plurality of search space sets (SSs) associated with the B-CORESET and each V-CORESET for monitoring positions in the frequency domain across multiple LBT subbands to improve downlink control information transmission. According to some aspects, the UE defines a frequency offset O i , where i represents the number corresponding to a listen-before-talk (LBT) subband within a serving cell, and each V-CORESET is mapped to an LBT subband based on Oi. According to some aspects, the UE uses higher layer signaling to receive a configuration of the frequency offset Oi for each corresponding subband and associates search spaces corresponding to each B-CORESET or V-CORESET. Some aspects include the UE using radio resource control (RRC) layer signaling to receive the configuration of the frequency offset O i i. Further, the UE may receive an indicator using bitmap signaling that provides information about which LBT subbands the CORESET configured by RRC signaling maps to.

[0021] Some aspects of the present disclosure include apparatuses and methods for implementing a mechanism for enhancing downlink control channel paging occasion monitoring between an electronic device and a network.

[0022] A UE operating in New Radio (NR) may be configured to utilize a bandwidth smaller than the system bandwidth. The UE bandwidth within a carrier, configured by a base station (BS) as the number of contiguous physical resource blocks (PRBs) with an associated subcarrier spacing (SCS), is referred to as a bandwidth part (BWP). Once a BWP is activated, data and control channels are received / transmitted within the BWP. A UE may be configured with multiple BWPs, each with a different SCS and may overlap or not overlap with each other in frequency. If more than one BWP is configured for a UE, the BS may select, via downlink (DL) control, which BWP is active at a given time. The physical downlink control channel (PDCCH) in NR carries downlink control information (DCI).

[0023] Accordingly, the BS may configure the UE bandwidth dynamically according to the UE's data traffic. Reduction of the UE bandwidth may reduce UE power consumption. The physical downlink control channel (PDCCH) controls, for example, DL scheduling allocations, UL scheduling grants, and special purposes such as slot format indication, preemption indication, and power control. The DCI contains scheduling information for UL or DL data channels and other control information for one UE or a group of UEs. In the case of operation in NR-U, the DCI format may include additional fields for transmitting control information

[0024] Resource Set (CORESET) Controlled within a Subband

[0025] In NR-U, a BS (such as an eNB or gNB) monitors a radio channel to determine whether it is authorized to use the channel based on the listen-before-talk (LBT) mechanism. Once LBT is granted for a certain subband, the BS can transmit (PDCCH, data, etc.) to the UE on that subband. DCI is mapped to physical resources in a given BWP, and necessary parameters (e.g., frequency-domain and time-domain resources, etc.) are configured to the UE by means of a control resource set (CORESET). A UE can be configured with more than one CORESET on each BWP of a serving cell. In one example, a UE can be configured with up to three CORESETS on each of four BWPs, for a total of twelve CORESETS configured on the serving cell. When a UE's BWP includes multiple subbands (e.g., more than one 20 MHz subband), puncturing of PDCCH candidates (i.e., LBT failures for some of the BWP subbands in the BWP subbands) can occur across multiple subbands. In some aspects, a UE can be configured to receive a PDCCH that is constrained within a single LBT subband to reduce puncturing. Specifically, an NR-U CORESET can be configured within a subband that can be replicated in the subbands of a BWP, as if the same CORESET were configured separately. Doing so helps reduce the complexity of processing additional CORESETS and the configuration overhead. A single CORESET can be configured within a subband, and an associated search space set (SS) can be configured with multiple monitoring positions in the frequency domain across multiple LBT subbands to increase the PDCCH transmission probability through LBT operations. According to some aspects, a UE can be configured such that one or more CORESETS are indexed according to their associated BWP. In some aspects, in addition to the CORESET associated with the initial BWP, one or more CORESETS are active only when their associated BWP is active.

[0026] Some aspects describe power-saving methods, systems, and devices that provide reduced PDCCH monitoring operations for a UE. Radio frequency (RF) chains and baseband (BB) processors consume a significant amount of power in a UE due to PDCCH monitoring in the absence of scheduled data. Aspects include PDCCH monitoring control. Some aspects include an indicator (e.g., a power-saving mode indicator) provided to control the PDCCH monitoring behavior of a UE, for example, according to data traffic. In some aspects, the indicator enables a UE to dynamically control its PDCCH monitoring behavior.

[0027] An indicator (such as an indicator of power saving mode configuration) can be transmitted by PDCCH, and the PDCCH monitoring occasion is located before the discontinuous reception (DRX) cycle. The power saving mode indicator can provide an indication of whether the UE skips one or more subsequent monitoring occasions within the DRX. Thus, the UE can be configured to monitor the PDCCH only when there is scheduled data. Thereby, power consumption can be improved with minimal latency loss.

[0028] In NR, the UE performs blind decoding for a set of PDCCH candidates. The PDCCH candidates to be monitored are configured for the UE by means of a search space (SS) set. There are two types of SS sets: a common SS (CSS) set that is typically monitored by a group of UEs in a cell, and a UE-specific SS (USS) set that is monitored by an individual UE. The UE can be configured with multiple SS sets for each BWP in the serving cell (e.g., up to 10 SS sets, each for up to four BWPs). The SS set configuration can provide the UE with the SS set type (CSS set or USS set), the DCI format to be monitored, the monitoring occasion, and the number of PDCCH candidates.

[0029] Regarding paging, a UE operating in NR (including NR-U) can be configured to monitor one paging occasion (PO) per DRX cycle. A PO is a set of PDCCH monitoring occasions, which can include multiple time slots (e.g., subframes or OFDM symbols) in which paging DCI can be transmitted. A paging frame (PF) can contain one or more POs or the starting points of POs.

[0030] Increasing Paging Opportunities

[0031] After LBT confirmation for a given subband, the BS (e.g., gNB) transmits information (such as PDCCH) to the UE on the subband. To avoid PDCCH candidate puncturing, constraints within the subband are achieved through NR-UCORESET configuration.

[0032] The latency involved in paging transmission is directly related to the call connection latency. This becomes an especially important issue for a stand-alone system where the PCell is on unlicensed spectrum. If the gNB does not transmit paging due to LBT, the paging transmission will have to be delayed until the next available occasion.

[0033] To solve this problem, the number of PDCCH monitoring occasions can be increased during the DRX cycle. That is, the network increases the chance of scheduling paging within multiple PDCCH monitoring occasions (e.g., multiple PDCCH monitoring occasions configured by radio resource control (RRC) signaling). In some non-limiting examples, the UE is associated with multiple consecutive or non-consecutive POs.

[0034] Between PDCCH monitoring occasions, the UE may be configured to defer monitoring in order to save power. The network is configured to ensure that the POs for two UE paging groups do not overlap. To further reduce the UE's power consumption in NR-U, the interval between the monitored POs may be reduced, with little to no extension of the UE's latency in receiving the page.

[0035] Managing UE Power Consumption

[0036] As the number of PDCCH monitoring occasions increases, even more paging transmission opportunities are provided for the base station (e.g., gNB), and the UE faces challenges in managing power consumption, especially when there is no paging transmission for the UE. The network and the UE may be configured to assume the presence of signals (such as demodulation reference signals (DMRS) in any transmission (such as PDCCH or GC-PDCCH)) to detect transmission bursts from the serving gNB, thereby achieving power savings.

[0037] For NR communication on the unlicensed band (NR-U), one or more UEs may be configured to support multiple PDCCH monitoring occasions for paging within one DRX cycle. By doing so, timely paging delivery after LBT can be achieved by increasing the paging transmission opportunities per DRX cycle.

[0038] However, as mentioned above, the increased PDCCH monitoring occasions have the potential to cause excessive UE power consumption. According to some aspects, the UE may be configured to perform one or more PDCCH monitoring occasions, i.e., paging monitoring occasions, and skip or discard one or more PDCCH monitoring occasions to achieve paging delivery with improved UE power consumption during PDCCH monitoring. As discussed in detail below, the PDCCH monitoring occasions can be coordinated between the BS and one or more UEs to minimize paging delivery latency while improving UE power consumption.

[0039] Timer-Based PDCCH Monitoring

[0040] According to some aspects, a paging inactivity timer (e.g., "paging_InactivityTimer") may be defined to limit PDCCH PO monitoring, with little to no impact on latency. For example, paging_InactivityTimer may be defined to represent the duration or number of monitoring occasions for PDCCH candidates in DCI format 1_0, where the cyclic redundancy check (CRC) is scrambled with the paging radio network temporary identifier (P-RNTI) after the PDCCH occasion indicating paging message transmission.

[0041] In some examples, the value of paging_InactivityTimer can be configured by a system information block or a dedicated RRC message for a given UE.

[0042] In some aspects, if a UE detects a P-RNTI in its addressed DRX cycle, the UE may stop monitoring additional paging PDCCH occasions in the DRX cycle. In other aspects, the UE may be configured to stop monitoring additional paging PDCCH POs in the DRX cycle as long as the UE detects a PDCCH with a P-RNTI. For example, the UE may be configured to stop monitoring additional POs when the UE detects a PDCCH with a P-RNTI, regardless of whether the paging message is addressed to the UE_ID of the given UE determined by the international mobile subscriber identity (IMSI).

[0043] In some aspects, the UE may start or restart paging_InactivityTimer after the end of PDCCH reception. For example, if the BS accesses the channel based on the detection of a PDCCH or other DL signals (e.g., PBCH, SS block, DRS), the UE may detect activity and restart paging_InactivityTimer when the UE does not detect a P-RNTI addressed to the UE. Thus, additional opportunities for paging transmission can be effectively provided to ensure paging message delivery.

[0044] Additionally, if paging_InactivityTimer expires, the UE stops monitoring the PDCCH for paging in the DRX cycle. As Figure 4 shown, an example of a timer-based PDCCH monitoring configuration 400 is provided. Figure 4 The exemplary configuration shown presents but is not limited to five paging monitoring occasions configured within the DRX cycle. Additionally, the example is shown as but not limited to a value of paging_InactivityTimer provided as two (i.e., monitoring two paging occasions within the DRX, after which monitoring is interrupted). If the UE (e.g., Figure 1If the UE 105) in detects downlink control information including paging message information (e.g., PDCCH with encrypted P-RNTI signal), the UE will start the paging_InactivityTimer even if it is not addressed. In this example, the UE starts the paging_InactivityTimer from the PDCCH monitoring occasion 410. The UE will stop monitoring the PDCCH occasions 430 and 440 for paging within the DRX cycle 420 because the paging_InactivityTimer expires starting from 430. In some aspects, the physical signaling can be configured to allow the UE to stop monitoring additional PDCCH occasions according to one or more exemplary procedures.

[0045] According to one example, the presence of signals such as DMRS in any PDCCH or GC-PDCCH transmission is used to detect the transmission burst of the gNB. More specifically, the DMRS can be broadband DMRS, and the group common PDCCH (GC-PDCCH) carries the channel occupancy time (COT) information in the time domain or frequency domain.

[0046] According to another example, depending on the RRC state, different channels can be used to provide an indicator for discarding one or more paging monitoring occasions. For example, for a UE in the idle mode (RRC_IDLE UE), the PDCCH transmission addressed to SI-RNTI or SSB or the PDSCH carrying the remaining minimum system information (RMSI) / other system information (OSI) can be used to indicate PO skipping. For a UE in the connected mode (e.g., RRC_CONNECTED state), any scheduled PDSCH / PDCCH transmission or channel state information reference signal (CSI-RS) transmission can be used as a field of the indicator. In some designs, to ensure the detection reliability of the CSI-RS signal, certain restrictions on the resource element (RE) density within a resource block (RB) can be specified. For example, a 3-RE / each RB configuration of CSI-RS, such as the tracking reference signal (TRS).

[0047] According to other aspects, the UE can be configured to receive an information element (IE) added to the paging message. The IE indicates whether the UE is to enter the skip paging monitoring (i.e., power saving) mode. As described above, in the power saving mode, the UE can skip additional paging occasions for PDCCH monitoring within the same DRX cycle.

[0048] For example, an Abstract Syntax Notation One (ASN.1) specification can be provided to define the IE ("SkipPagingMonitoring") as follows:

[0049]

[0050] According to an additional aspect, the network may configure the UE on whether to stop monitoring additional PDCCH monitoring occasions within the DRX cycle after detecting a P-RNTI not addressed to the UE.

[0051] According to an additional aspect, an information field may be added to the DCI format to indicate whether a PDCCH monitoring occasion in the same DRX cycle can be skipped. As Figure 5 shown, DCI format 500 may be provided based on DCI format 1_0. In this example, DCI 500 is configured to add an information field 510 to DCI format 1_0, where the information field 510 represents a PDCCH skip indicator. Additionally, as shown, DCI 500 includes a CRC encrypted by the P-RNTI. In other non-limiting examples (not shown), one or more'reserved' bits of Rel-15 DCI format 1_0 may be reinterpreted as indicators, i.e., to indicate skipping or interrupting additional PDCCH monitoring occasions for paging in the same DRX cycle.

[0052] Search Space Configuration for PDCCH Monitoring on a CC with Multiple LBT Subbands

[0053] As described above, some aspects include a single CORESET configured within a subband. According to some aspects, an associated search space set (SS) may be configured with multiple monitoring positions in the frequency domain across multiple LBT subbands. By configuring for multiple monitoring positions, the PDCCH transmission probability can be increased during LBT operation.

[0054] As Figure 6 shown, according to some aspects, for a serving cell with a carrier bandwidth greater than the LBT bandwidth, a base CORESET (B-CORESET 620) and one or more virtual CORESETs (V-CORESET) 621, 622, or 623 may be mapped within each respective LBT subband 610, 611, 612, or 613 based on a frequency offset. From a signaling perspective, only the B-CORESET is configured, and the V-CORESET (e.g., three V-CORESETs) is copied from the B-CORESET. That is, the V-CORESET is propagated by the UE by copying the configured B-CORESET. In one non-limiting example, a frequency offset O i may be mapped between the base CORSET (B-CORESET) and the lowest physical resource block (PRB) of V-CORESET i. In this example, i represents the number of the LBT subband within the serving cell.

[0055] As Figure 6 shown, one or more frequency offsets O in resource block (RB) units iIt can be configured by higher-layer signaling. In a non-limiting example, the frequency offset O i can be configured on a per-subband basis via RRC signaling. The search space can be associated with B-CORESET 620 or one or more of V-CORESETs 621 to 623, which are configured as part of the search space configuration. According to other aspects, bitmap signaling can be used to indicate which LBT subbands the CORESET configured via RRC signaling maps to.

[0056] Figure 1 Exemplary system 100 shows a mechanism for carrier / cell detection and measurement by performing downlink control channel PO monitoring between an electronic device and a network according to some aspects of the present disclosure. Exemplary system 100 is provided for illustrative purposes only and does not limit the disclosed aspects. System 100 may include, but is not limited to, network nodes (e.g., base stations such as eNBs) 101 and 103 and an electronic device (e.g., UE) 105. The electronic device 105 (hereinafter referred to as UE 105) may include an electronic device configured to operate based on multiple wireless communication technologies. These technologies may include, but are not limited to, technologies based on the 3rd Generation Partnership Project (3GPP) standards. For example, UE 105 may include an electronic device configured to operate using Release 17 (Rel-17) or later versions. UE 105 may include, but is not limited to, wireless communication devices, smart phones, laptops, desktop computers, tablets, personal assistants, monitors, televisions, wearable devices, Internet of Things (IoT), vehicle communication devices, etc. The network nodes 101 and 103 (referred to herein as base stations) may include nodes configured to operate based on multiple wireless communication technologies (such as, but not limited to, technologies based on 3GPP standards). For example, base stations 103 and 105 may include nodes configured to operate using Release 17 (Rel-17) or later versions.

[0057] According to some aspects, UE 105 and base stations 101 and 103 are configured to implement a mechanism for downlink control channel PO monitoring between UE 101 and the network associated with base stations 101 and 103 for carrier / cell detection and measurement. According to some aspects, UE 105 may be connected to and communicate with base station 101 using carrier 107. According to some aspects, carrier 107 may include one carrier. Additionally, or alternatively, carrier 107 may include two or more component carriers (CCs). In other words, UE 105 may implement carrier aggregation (CA). For example, the UE may use multiple carriers to communicate with base station 101. In some examples, the UE may use a primary component carrier (PCC) with one or more secondary component carriers (SCCs). The carriers may be used with frequency division duplexing (FDD), time division duplexing or a hybrid of TDD and FDD. In some examples, the PCC may be used for control signaling and the SCCs may be used for data. However, aspects of the present disclosure are not limited to these examples.

[0058] According to some aspects, UE 105 is configured to coordinate downlink control channel PO monitoring with base station 101 and / or the network associated with base station 101 (and / or 103). For example, prior to or during the process of communicating with base station 101, UE 105 may define a paging inactivity timer to enhance or limit PDCCH monitoring. For example, and as described above, UE 105 may define paging_InactivityTimer to represent the duration or number of monitoring opportunities for PDCCH candidates. In some aspects, after a PDCCH occasion indicating paging message transmission, UE 105 may define paging_InactivityTimer based on DCI format 1_0 with a CRC scrambled with P-RNTI. In some examples, the value of paging_InactivityTimer may be configured by a system information block or a dedicated RRC message for a given UE.

[0059] In some aspects, if UE 105 detects a P-RNTI addressed to it in a DRX cycle, the UE may stop monitoring additional paging PDCCH occasions in the DRX cycle. In other aspects, UE 105 may be configured to stop monitoring additional paging PDCCH POs in the DRX cycle only if the UE detects a PDCCH with a P-RNTI. For example, the UE may be configured to stop monitoring additional POs if the UE detects a PDCCH with a signal encrypted with P-RNTI, regardless of whether the paging message is addressed to the universal unique identifier (UUID) of a given UE.

[0060] In some aspects, the UE may start or restart the paging_InactivityTimer after the PDCCH reception ends. For example, if the BS accesses the channel based on the PDCCH or other DL signals (e.g., PBCH, SS block, DRS), the UE may detect activity and restart the paging_InactivityTimer when the UE does not detect a P-RNTI addressed to the UE. Thus, additional opportunities for paging transmission can be effectively provided.

[0061] Additionally, if the paging_InactivityTimer expires, UE 105 stops monitoring the PDCCH for paging in the DRX cycle. As Figure 4 shown, once UE 105 detects a PDCCH including a signal encrypted with the P-RNTI (even if it is not addressed), UE 105 will start the paging_InactivityTimer from the PDCCH monitoring occasion 410. When the paging_InactivityTimer expires starting from 430, UE 105 will stop monitoring the PDCCH occasions 430 and 440 for paging within the DRX cycle 420.

[0062] In some aspects, the physical signaling may be configured to allow UE 105 to stop monitoring additional PDCCH occasions according to one or more exemplary procedures.

[0063] According to one example, the presence of signals such as DMRS in any PDCCH or GC-PDCCH transmission enables UE 105 to detect the transmission burst of the gNB. More specifically, the DMRS may be a broadband DMRS, and the group common PDCCH (GC-PDCCH) carries the channel occupancy time (COT) information in the time domain or frequency domain.

[0064] According to another example, depending on the RRC state, different channels may be used to provide an indicator for discarding one or more paging monitoring occasions. For example, for a UE in the idle mode (RRC_IDLE UE), the PDCCH transmission addressed to the SI-RNTI or SSB or the PDSCH carrying the remaining minimum system information (RMSI) / other system information (OSI) can be used to indicate PO skipping. For a UE in the connected mode (e.g., RRC_CONNECTED state), any scheduled PDSCH / PDCCH transmission or channel state information reference signal (CSI-RS) transmission can be used as a field of the indicator. In some designs, to ensure the detection reliability of the CSI-RS signal, certain restrictions on the resource element (RE) density within a resource block (RB) may be specified. For example, a 3-RE / each RB configuration of CSI-RS, such as the tracking reference signal (TRS).

[0065] According to other aspects, the UE may be configured to receive an information element (IE) added to a paging message. This IE indicates whether the UE is to enter a skipped paging monitoring (i.e., power saving) mode. As described above, in the power saving mode, the UE may skip additional paging occasions for PDCCH monitoring within the same DRX cycle.

[0066] For example, an Abstract Syntax Notation One (ASN.1) specification may be provided to define the IE ("SkipPagingMonitoring") as follows:

[0067]

[0068] According to additional aspects, the network may configure the UE as to whether to stop monitoring additional PDCCH monitoring occasions within a DRX cycle after detecting a P-RNTI not addressed to the UE.

[0069] According to additional aspects, a new information field may be added to the DCI format to indicate whether PDCCH monitoring occasions within the same DRX cycle may be skipped. As Figure 5 shown, one non-limiting example adds the information field 510 to DCI format 1_0 having a CRC scrambled by a P-RNTI. In other non-limiting examples, portions of the 'reserved' bits of Rel-15 DCI format 1-0 may be reinterpreted to indicate skipping of additional PDCCH monitoring occasions for paging within the same DRX cycle.

[0070] Figure 2 FIG. 200 is a block diagram of an exemplary system of an electronic device implementing a mechanism for monitoring downlink control information (including monitoring paging occasions) in accordance with some aspects of the present disclosure. System 200 may be any electronic device of System 100 (e.g., base stations 101, 103, UE 105). System 200 includes a processor 210, one or more transceivers 220a-220n, a communication infrastructure 240, a memory 250, an operating system 252, an application 254, and an antenna 260. The illustrated systems are provided as exemplary portions of System 200, and System 200 may include other circuitry and subsystems. Additionally, although the systems of System 200 are shown as separate components, aspects of the present disclosure may include any combination of these components, fewer components, or more components.

[0071] Memory 250 may include random access memory (RAM) and / or cache, and may include control logic (e.g., computer software) and / or data. Memory 250 may include other storage devices or memories, such as but not limited to hard disk drives and / or removable storage devices / units. According to some examples, operating system 252 may be stored in memory 250. Operating system 252 may manage data transfer from memory 250 and / or one or more application programs 254 to processor 210 and / or one or more transceivers 220a - 220n. In some examples, operating system 252 maintains one or more network protocol stacks (e.g., Internet protocol stack, cellular protocol stack, etc.) that may include multiple logical layers. At the corresponding layers of the protocol stack, operating system 252 includes control mechanisms and data structures to perform functions associated with that layer.

[0072] According to some examples, application programs 254 may be stored in memory 250. Application programs 254 may include applications used by wireless system 200 and / or users of wireless system 200 (e.g., user applications). Applications in application programs 254 may include applications such as but not limited to the following: Siri TM , FaceTime TM , wireless current, video stream, remote control, and / or other user applications.

[0073] System 200 may also include communication infrastructure 240. Communication infrastructure 240 provides communication, for example, between processor 210, one or more transceivers 220a - 220n, and memory 250. In some embodiments, communication infrastructure 240 may be a bus. Processor 210, together with instructions stored in memory 250, performs operations that enable wireless system 200 of system 100 to implement the mechanisms for monitoring downlink control information (including monitoring paging occasions) as described herein. Additionally or alternatively, one or more transceivers 220a - 220n perform operations that enable system 200 of system 100 to implement the mechanisms for monitoring downlink control information (including monitoring paging occasions) as described herein.

[0074] According to some aspects, one or more transceivers 220a - 220n transmit and receive communication signals that support a mechanism for monitoring downlink control information (including monitoring paging opportunities), and may be coupled to an antenna 260. The antenna 260 may include one or more antennas that may be of the same or different types. The one or more transceivers 220a - 220n allow the system 200 to communicate with other devices that may be wired and / or wireless. In some examples, the one or more transceivers 220a - 220n may include a processor, a controller, radio components, sockets, plugs, buffers, and similar circuits / devices for connecting to and communicating on a network. According to some examples, the one or more transceivers 220a - 220n may include one or more circuits for connecting to a wired network and / or a wireless network and communicating on the wired network and / or the wireless network.

[0075] According to some aspects of the present disclosure, one or more transceivers 220a - 220n may include a cellular subsystem, a WLAN subsystem, and / or a Bluetooth TM subsystem, each including its own radio transceiver and protocol, as will be understood by those skilled in the art based on the discussion provided herein. In some embodiments, the one or more transceivers 220a - 220n may include more or fewer systems for communicating with other devices.

[0076] In some examples, the one or more transceivers 220a - 220n may include one or more circuits (including a WLAN transceiver) for enabling connection and communication via a WLAN network (such as, but not limited to, a network based on the standards described in IEEE 802.11).

[0077] Additionally or alternatively, the one or more transceivers 220a - 220n may include one or more circuits (including a Bluetooth TM transceiver) for enabling connection and communication based on, for example, the Bluetooth TM protocol, the Bluetooth TM low energy protocol, or the Bluetooth TM low energy remote protocol. For example, transceiver 220n may include a Bluetooth TM transceiver.

[0078] Additionally, one or more transceivers 220a - 220n may include one or more circuits (including a cellular transceiver) for connecting to and communicating over a cellular network. The cellular network may include, but is not limited to, 3G / 4G / 5G networks such as Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), etc. For example, one or more transceivers 220a - 220n may be configured to operate according to one or more of Rel - 15, Rel - 16, Rel - 17, or later versions of the 3GPP standards.

[0079] According to some aspects of the present disclosure, the processor 210 alone or in combination with computer instructions stored in the memory 250 and / or one or more transceivers 220a - 220n implements the paging occasion monitoring discussed herein. For example, transceiver 220a may achieve connection and communication via a first carrier (e.g., Figure 1 carrier 107). In this example, concurrently, transceiver 220b may enable detection and / or measurement of a second carrier (e.g., Figure 1 carrier 109), transceiver 220c may enable detection and / or measurement of a third carrier, and transceiver 220n may enable detection and / or measurement of a fourth carrier. As described above, the first carrier, the second carrier, the third carrier, and the fourth carrier may be associated with the same or different base stations.

[0080] Additionally, or alternatively, the wireless system 200 may include one transceiver configured to operate on different carriers. According to some examples, the processor 210 may be configured to control one transceiver to switch between different carriers.

[0081] According to some aspects of the present disclosure, the processor 210 alone or in combination with computer instructions stored in the memory 250 and / or one or more transceivers 220a - 220n implements the mechanism for monitoring downlink control information (including monitoring paging occasions) as discussed herein. Although the operations discussed herein are described with respect to the processor 210, it should be noted that the processor 210 may implement these operations alone or in combination with computer instructions stored in the memory 250 and / or one or more transceivers 220a - 220n. For example, the processor 210 is configured to monitor the paging occasion of the system 200 from a base station (and / or the network associated with the base station) during the initial communication (or any other initial access) discussed above as per UE capabilities. The processor 210 may use RRC layer signaling, MAC layer, and / or PHY layer signaling to configure paging occasion monitoring as per UE capabilities.

[0082] In another example, the processor 210 may be configured to monitor the paging occasions of the system 200 from the base station (and / or the network associated with the base station) during the initial communication (or any other initial access) discussed above as per FR capabilities. The processor 210 may use RRC layer signaling, MAC layer, and / or PHY layer signaling to configure the paging occasion monitoring as per FR capabilities.

[0083] In some examples, the processor 210 may be configured to monitor the paging occasions of the base station (and / or the network associated with the base station) using the release version of the system 200. For example, the release version 256 stored in the memory 250, for instance, may indicate whether the system 200 is configured to operate in one or more of Rel-16, Rel-15, or earlier versions and / or Rel-17 or later versions. The processor 210 may generate and transmit a signal including / indicating the release version 256. In these examples, the base station (and / or the network associated with the base station) may configure the paging occasions associated with the system 200 based on the release version 256.

[0084] As discussed in more detail below with respect to Figure 7 and Figure 8 the processor 210 may implement different mechanisms for monitoring downlink control information in the Figure 1 system 100. Figure 7 FIG. shows an exemplary method 700 of a system (e.g., a user equipment (UE)) for supporting mechanisms for monitoring downlink control information in accordance with some aspects of the present disclosure. For convenience and not limitation, the elements may be described with reference to Figure 1 and Figure 2 as well as Figure 10 The elements of Figure 7 , Figure 8 and Figure 9 . As Figure 7 shown, the method 700 may represent the operation of an electronic device (e.g., Figure 1 the UE105) implementing mechanisms for monitoring downlink control information. The method 700 may also be executed by Figure 2 the system 200 and / or Figure 10 the computer system 1000. However, the method 700 is not limited to the specific aspects depicted in those figures and may be executed using other systems, as will be understood by those skilled in the art. It should be understood that not all operations may be required and that these operations may not be executed in the same order as Figure 7 shown.

[0085] At 705, a UE, such as one that receives communications from a network, monitors at least one paging occasion among multiple paging occasions within a discontinuous reception (DRX) cycle. For example, a UE (e.g., UE 105) may be configured to listen for one or more paging occasions within the DRX. For example, UE 105 is configured to monitor for the presence of a signal (such as a signal encrypted by a P-RNTI) on the PDCCH that contains a paging message. UE 105 may continue to monitor for paging messages. In NR-U, UE 105 may be configured to support multiple PDCCH monitoring occasions for paging within a DRX cycle. Increasing the paging transmission opportunities per DRX cycle improves the timeliness of paging delivery in LBT communications, but may result in excessive UE power consumption. According to some aspects, monitoring a paging occasion at 705 includes monitoring PDCCH communications.

[0086] At 710, the UE determines not to monitor one or more paging occasions among the multiple paging occasions within the same DRX, as discussed at 710. A paging occasion may include an opportunity for the network to transmit downlink control information for a paging message to one or more UEs. That is, UE 105 performs one or more paging monitoring occasions at 705 and skips or ignores one or more PDCCH monitoring occasions at 710. Thus, UE 105 may achieve timely paging delivery with improved UE power consumption by skipping one or more paging occasions. As discussed in detail below, the PDCCH monitoring occasions may be coordinated between the BS and one or more UEs to minimize paging delivery latency while improving UE power consumption. Some aspects include using physical signaling such as higher layer signaling to configure the UE to stop monitoring additional PDCCH occasions. In one example, the UE detects a transmission burst of the gNB by listening for a signal such as the presence of DMRS in any PDCCH or GC-PDCCH transmission. More specifically, the DMRS may be a broadband DMRS, and the group common PDCCH (GC-PDCCH) carries channel occupancy time (COT) information in the time domain or frequency domain.

[0087] According to another example, depending on the RRC state, different channels can be used to provide an indicator for discarding one or more paging monitoring occasions. For example, for a UE in the idle mode (RRC_IDLE UE), PDCCH transmissions addressed to SI-RNTI or SSB, or PDSCH carrying the remaining minimum system information (RMSI) / other system information (OSI) can be used to indicate PO skipping. For a UE in the connected mode (e.g., RRC_CONNECTED state), any scheduled PDSCH / PDCCH transmission or channel state information reference signal (CSI-RS) transmission can be used as a field for the indicator. In some designs, to ensure the detection reliability of the CSI-RS signal, certain restrictions on the resource element (RE) density within a resource block (RB) can be specified. For example, a 3-RE / each RB configuration of CSI-RS, such as a tracking reference signal (TRS).

[0088] According to other aspects, the UE 105 can be configured to receive an information element (IE) added to the paging message. The IE indicates whether the UE 105 is to enter the skip paging monitoring (i.e., power saving) mode. As described above, in the power saving mode, the UE can skip additional paging occasions for PDCCH monitoring within the same DRX cycle. An example is provided above regarding the 'SkipPagingMonitoring' IE.

[0089] According to additional aspects, the UE 105 can be configured by the network to determine whether to stop monitoring additional PDCCH monitoring occasions within the DRX cycle after detecting a P-RNTI not addressed to the UE 105.

[0090] According to additional aspects, a new information field can be added to the DCI format to indicate whether the PDCCH monitoring occasion within the same DRX cycle can be skipped. As Figure 5 shown, a non-limiting example adds the information field 510 to the DCI format 1_0 with a CRC scrambled by P-RNTI. In other non-limiting examples, a part of the'reserved' bits of the Rel-15 DCI format 1-0 can be reinterpreted to indicate the skipping of additional PDCCH monitoring occasions for paging within the same DRX cycle.

[0091] At 715, the UE can use the downlink control information to decide whether to receive one or more paging messages. For example, if the downlink control information includes an address associated with the UE, the UE 105 processes the paging message. Otherwise, the UE 105 can discard the downlink control information and continue with operation 705 or 710.

[0092] According to some aspects, the processor 210 may implement a process for monitoring downlink control information that includes dependencies on timers, counters, or other means for enumerating paging occasions or durations. Figure 8 An exemplary method 800 of a system (e.g., a user equipment (UE)) for supporting a mechanism for monitoring downlink control information (including enhanced monitoring of paging occasions) in accordance with some aspects of the present disclosure is shown. For convenience and not limitation, reference may be made to Figure 1 and Figure 2 and Figure 10 the elements of Figure 8 . Method 800 may represent operations of an electronic device (e.g., Figure 1 UE 105) implementing a mechanism for monitoring downlink control information (including monitoring paging occasions). The foregoing disclosure of method 700 applies to method 800.

[0093] At 805, a paging inactivity timer (e.g., "paging_InactivityTimer") is defined to correspond to a value. For example, the paging inactivity timer value may correspond to the duration of a paging occasion. In another example, the paging inactivity timer value may correspond to the number of paging occasions (e.g., the number of paging occasions to be monitored within the current DRX).

[0094] At 810, at least one paging occasion among a plurality of paging occasions within a discontinuous reception cycle (DRX) is monitored, e.g., by a UE receiving communications from a network. For example, a UE (e.g., UE105) may be configured to listen for one or more paging occasions within the DRX. For example, UE 105 is configured to monitor the presence of a signal (such as a signal encrypted by P-RNTI) on the PDCCH containing a paging message. UE 105 may continue to monitor for paging messages. In NR-U, UE 105 may be configured to support multiple PDCCH monitoring occasions for paging within a DRX cycle. Increasing the paging transmission opportunities per DRX cycle improves the timeliness of paging delivery in LBT communications but may result in excessive UE power consumption. According to some aspects, monitoring a paging occasion at 705 includes monitoring PDCCH communications. According to some aspects, if the paging_InactivityTimer expires, UE 105 stops monitoring for paging occasions within the DRX cycle. For example, as Figure 4 shown, an example of timer-based PDCCH monitoring adaptation assumes that five paging monitoring occasions are configured within a DRX cycle and the value of the paging_InactivityTimer is two.

[0095] Once the UE 105 detects downlink control information associated with a paging message (e.g., a PDCCH including P-RNTI encryption), even if not addressed to the UE 105, the UE 105 will start the paging_InactivityTimer from the PDCCH monitoring occasion 410. In this non-limiting example, the UE 105 does not monitor the paging occasions 430 and 440 within the DRX cycle 420. Some aspects of the present invention include that the paging inactivity timer can be configured by a system information block or a dedicated RRC message for the UE 105.

[0096] At 815, the UE 105 determines not to monitor one or more paging occasions among multiple paging occasions within the same DRX based on the paging inactivity timer. For example, if the paging inactivity timer increases the time or count of the monitored paging occasions and reaches a limit value, the UE 105 can be configured to interrupt the paging occasions within the DRX. Additionally or alternatively, if the UE detects a P-RNTI addressed to it in the DRX cycle, the UE 105 can be configured to stop monitoring additional paging PDCCH occasions in the DRX cycle. Similar to the method 700, the UE 105 performs one or more paging monitoring occasions at 710 and skips or ignores one or more PDCCH monitoring occasions at 815 to improve UE power consumption.

[0097] In some aspects, the UE 105 can start or restart the paging inactivity timer after receiving the downlink control information, e.g., after the end of PDCCH reception. For example, if the BS accesses the channel based on the PDCCH or other DL signals (e.g., PBCH, SS block, DRS), the UE 105 can detect activity and restart the paging_InactivityTimer when the UE does not detect a P-RNTI addressed to the UE.

[0098] At 820, the UE 105 can use the downlink control information to decide whether to receive one or more paging messages. For example, if the downlink control information includes an address associated with the UE, the UE 105 processes the paging message. Otherwise, the UE 105 can discard the downlink control information and continue with operation 705 or 710.

[0099] In addition, as discussed in more detail below regarding Figure 9 The processor 210 can also implement different mechanisms for configuring and propagating an NR-U CORESET within a subband (i.e., a single subband of the BWP), which NR-U CORESET can be replicated in other subbands of the BWP as if the same CORESET was configured separately. Figure 9An exemplary method 900 of a system (e.g., a user equipment (UE)) for supporting a mechanism for copying a B-CORESET to one or more V-CORESETs according to some aspects of the present disclosure is shown. Without limitation, it may be described with reference to the elements of Figure 1 and Figure 2 as well as Figure 10 to describe Figure 9 . Method 900 may represent operations of an electronic device (e.g., the UE 105 of Figure 1 ) implementing a mechanism for configuring a CORESET (including configuring a V-CORESET by the electronic device). Method 900 may also be executed by the system 200 of Figure 2 and / or the computer system 1000 of Figure 10 . However, method 900 is not limited to the specific aspects depicted in those figures, and the method may be executed using other systems, as will be understood by those skilled in the art. It should be understood that not all operations may be required, and these operations may not be executed in the same order as shown in Figure 9 .

[0100] At 905, the UE 105 receives a control resource set (CORESET) configuration defining a mapping of physical resources in a bandwidth part (BWP), where the BWP includes a plurality of subbands (i.e., LBT subbands).

[0101] At 910, the UE 105 configures a base CORESET (B-CORESET) within a single subband (e.g., an LBT subband) of the plurality of subbands based on the CORESET configuration received by the UE.

[0102] At 915, the UE 105 copies the B-CORESET into one or more virtual CORESETs (V-CORESETs). Each V-CORESET among the one or more V-CORESETs may be copied into a corresponding one or more subbands (e.g., other subbands) of the BWP. A plurality of search space sets (SS) associated with the B-CORESET and each V-CORESET may be configured for a plurality of monitoring positions in the frequency domain across the plurality of LBT subbands to increase the probability of downlink control information. According to some aspects, for each V-CORESET, the UE 105 defines a frequency offset O i , where i represents the number corresponding to the (LBT) subband within the serving cell. Based on O i , each V-CORESET is mapped to a subband, such as each LBT subband. Some aspects include the UE 105 receiving the frequency offset O i for each corresponding LBT subband via higher layer signalingconfiguration and associate search spaces corresponding to each B-CORESET or V-CORESET.

[0103] For example, UE 105 may receive, from the network, a frequency offset O for each corresponding subband using radio resource control (RRC) layer signaling i configuration. Additionally, UE 105 may receive bitmap signaling that includes indicators that include information regarding which LBT subbands are mapped by the CORESET configured by the RRC signaling.

[0104] For example, various aspects may be implemented using one or more computer systems such as Figure 10 the computer system 1000 shown in. The computer system 1000 may be any well-known computer capable of performing the functions described herein, such as Figure 1 devices 101, 103, 105 of, or Figure 2 device 200 of. The computer system 1000 includes one or more processors (also referred to as central processing units or CPUs), such as processor 1004. The processor 1004 is connected to a communication infrastructure 1006 (e.g., a bus). The computer system 1000 also includes user input / output devices 1003 that communicate with the communication infrastructure 1006 via a user input / output interface 1002, such as a monitor, keyboard, pointing device, etc. The computer system 1000 also includes a main memory or primary storage 1008, such as random access memory (RAM). The main memory 1008 may include one or more levels of cache. Control logic (e.g., computer software) and / or data is stored in the main memory 1008.

[0105] The computer system 1000 may also include one or more secondary storage devices or memories 1010.

[0106] The removable storage drive 1014 may interact with a removable storage unit 1018. The removable storage unit 1018 includes a computer-usable or readable storage device in which computer software (control logic) and / or data is stored. The removable storage unit 1018 may be a floppy disk, tape, optical disk, DVD, optical storage disk, and / or any other computer data storage device. The removable storage drive 1014 reads from and / or writes to the removable storage unit 1018 in a well-known manner.

[0107] According to some aspects, the secondary storage 1010 may include other devices, means, or other methods for allowing a computer system 1000 to access computer programs and / or other instructions and / or data. Such devices, means, or other methods may include, for example, removable storage units 1022 and interfaces 1020.

[0108] The computer system 1000 may also include a communication or network interface 1024. The communication interface 1024 enables the computer system 1000 to communicate and interact with any combination of remote devices, remote networks, remote entities, etc. (collectively and individually referred to by reference numeral 1028). For example, the communication interface 1024 may allow the computer system 1000 to communicate with a remote device 1028 via a communication path 1026, which may be wired and / or wireless and may include any combination of LAN, WAN, the Internet, etc. Control logic and / or data may be transmitted to and from the computer system 1000 via the communication path 1026.

[0109] The operations in the foregoing aspects can be implemented in a variety of configurations and architectures. Thus, some or all of the operations in the foregoing aspects may be performed in hardware, in software, or in both hardware and software. In some aspects, a tangible, non-transitory device or article includes a tangible, non-transitory computer-usable or readable medium having control logic (software) stored thereon, also referred to herein as a computer program product or program storage device.
