[0039] In wireless networks, such as 5G or 4G LTE networks, among others, scheduling restrictions arise from the need to balance various factors like latency, throughput, and fairness, and to support diverse traffic types, including those with stringent real-time requirements. This disclosure describes methods and systems for managing scheduling restrictions for one or more user equipments (UEs) in such wireless networks. Scheduling restrictions refer to constraints on resource allocation in downlink (DL) reception or uplink (UL) transmission, impacting how efficiently the network assigns resources to a UE. Managing scheduling restrictions refers to disabling or enabling scheduling restrictions. Disabling scheduling restrictions refers to a process where a base station removes or lifts certain limitations on DL or UL scheduling for a UE or a group of UEs. Enabling scheduling restrictions refers to a process where a base station applies limitations on the DL or UL scheduling for a UE or a group of UEs. Enabling scheduling restrictions can control how much data can be transmitted or received by the UE within a specific time or frequency.
[0040] In some implementations, a base station (e.g., a next generation nodeB, gNB) configures a power level threshold value for disabling scheduling restrictions for a UE in the cell coverage area of the base station. When the base station is informed that Cell (Re) Selection RX Level Value (Srxlev) of the UE is greater than the power level threshold value, indicating that the UE is close to or at the cell center, the base station can disable scheduling restrictions for the UE. In some implementations, the base station configures a power level threshold value and a signal quality threshold value for disabling scheduling restrictions for a UE in the cell coverage area of the base station. When the base station is informed that Srxlev is greater than the power level threshold value and Cell (Re) Selection Quality Value (Squal) is greater than the signal quality threshold value, indicating that the UE is close to or at the cell center, the base station can disable scheduling restrictions for the UE.
[0041] The disclosed techniques further include methods and systems for managing scheduling restrictions based on a UL power headroom report, which includes a UL power headroom value. The UL power headroom value indicates a difference between the maximum UL transmission power the UE can achieve and the actual power being used for UL transmission.
[0042] In some implementations, a predetermined duration (e.g., the number of slots / an amount of time) during which scheduling restrictions are enabled / disabled can be signaled by (i) Radio Resource Control (RRC) Reconfiguration; (ii) dynamic MAC Control Elements (MAC CEs) or semi-static MAC CEs; or (iii) dynamic Downlink Control Information (DCI) .
[0043] Also disclosed are methods and systems for managing simultaneous transmission (Tx) and reception (Rx) of signals for a UE. In some implementations, the network (e.g., the base station) allows simultaneous transmission (Tx) and reception (Rx) for a UE regardless of colliding DL channels. In some implementations, the network allows simultaneous Tx-Rx only if higher-priority DL channels are not colliding. In some examples, the network allows simultaneous Tx-Rx only outside the Physical Downlink Control Channel (PDCCH) control region. In some examples, the network allows simultaneous Tx-Rx only outside the Synchronization Signal Block (SSB) / Physical Broadcast Channel (PBCH) region.
[0044] FIG. 1 illustrates an example wireless network 100, according to some implementations. The wireless network 100 includes a UE 102 and a base station 104 connected via one or more channels 106A, 106B across an air interface 108. The UE 102 and base station 104 communicate using a system that supports controls for managing the access of the UE 102 to a network via the base station 104.
[0045] In some implementations, the wireless network 100 may be a Non-Standalone (NSA) network that incorporates Long Term Evolution (LTE) and Fifth Generation (5G) New Radio (NR) communication standards as defined by the Third Generation Partnership Project (3GPP) technical specifications. For example, the wireless network 100 may be an E-UTRA (Evolved Universal Terrestrial Radio Access) -NR Dual Connectivity (EN-DC) network, or an NR-EUTRA Dual Connectivity (NE-DC) network. In some other implementations, the wireless network 100 may be a Standalone (SA) network that incorporates only 5G NR. Furthermore, other types of communication standards are possible, including future 3GPP systems (e.g., Sixth Generation (6G) ) , Institute of Electrical and Electronics Engineers (IEEE) 802.11 technology (e.g., IEEE 802.11a; IEEE 802.11b; IEEE 802.11g; IEEE 802.11-2007; IEEE 802.11n; IEEE 802.11-2012; IEEE 802.11ac; or other present or future developed IEEE 802.11 technologies) , IEEE 802.16 protocols (e.g., WMAN, WiMAX, etc. ) , or the like. While aspects may be described herein using terminology commonly associated with 5G NR, aspects of the present disclosure can be applied to other systems, such as 3G, 4G, and / or systems subsequent to 5G (e.g., 6G) .
[0046] In the wireless network 100, the UE 102 and any other UE in the system may be, for example, any of laptop computers, smartphones, tablet computers, machine-type devices such as smart meters or specialized devices for healthcare, intelligent transportation systems, or any other wireless device. In network 100, the base station 104 provides the UE 102 network connectivity to a broader network (not shown) . This UE 102 connectivity is provided via the air interface 108 in a base station service area provided by the base station 104. In some implementations, such a broader network may be a wide area network operated by a cellular network provider, or may be the Internet. Each base station service area associated with the base station 104 is supported by one or more antennas integrated with the base station 104. The service areas can be divided into a number of sectors associated with one or more particular antennas. Such sectors may be physically associated with one or more fixed antennas or may be assigned to a physical area with one or more tunable antennas or antenna settings adjustable in a beamforming process used to direct a signal to a particular sector.
[0047] The UE 102 includes control circuitry 110 coupled with transmit circuitry 112 and receive circuitry 114. The transmit circuitry 112 and receive circuitry 114 may each be coupled with one or more antennas. The control circuitry 110 may include various combinations of application-specific circuitry and baseband circuitry. The transmit circuitry 112 and receive circuitry 114 may be adapted to transmit and receive data, respectively, and may include radio frequency (RF) circuitry and / or front-end module (FEM) circuitry.
[0048] In various implementations, aspects of the transmit circuitry 112, receive circuitry 114, and control circuitry 110 may be integrated in various ways to implement the operations described herein. The control circuitry 110 may be adapted or configured to perform various operations, such as those described elsewhere in this disclosure related to a UE. For instance, the control circuitry 110 can estimate CSI in response to CSI-RS from the base station 104.
[0049] Additionally, the transmit circuitry 112 may transmit using a plurality of multiplexed uplink (UL) physical channels. The plurality of uplink physical channels may be multiplexed, e.g., according to time division multiplexing (TDM) or frequency division multiplexing (FDM) along with carrier aggregation. The transmit circuitry 112 may be configured to receive block data from the control circuitry 110 for transmission across the air interface 108.
[0050] The receive circuitry 114 may receive a plurality of multiplexed downlink (DL) physical channels from the air interface 108 and relay the physical channels to the control circuitry 110. The plurality of downlink physical channels may be multiplexed, e.g., according to TDM or FDM along with carrier aggregation. The transmit circuitry 112 and the receive circuitry 114 may transmit and receive, respectively, both control data and content data (e.g., messages, images, video, etc. ) structured within data blocks that are carried by the physical channels.
[0051] FIG. 1 also illustrates the base station 104. In some implementations, the base station 104 may be a 5G radio access network (RAN) , a next-generation RAN, an E-UTRAN, a non-terrestrial cell, or a legacy RAN, such as a UTRAN. As used herein, the term “5G RAN” or the like may refer to the base station 104 that operates in an NR or 5G wireless network 100, and the term “E-UTRAN” or the like may refer to a base station 104 that operates in an LTE or 4G wireless network 100. The UE 102 utilizes connections (or channels) 106A, 106B, each of which includes a physical communications interface or layer.
[0052] The base station 104 circuitry may include control circuitry 116 coupled with transmit circuitry 118 and receive circuitry 120. The transmit circuitry 118 and receive circuitry 120 may each be coupled with one or more antennas that may be used to enable communications via the air interface 108. The transmit circuitry 118 and receive circuitry 120 may be adapted to transmit and receive data, respectively, to any UE connected to the base station 104. The receive circuitry 120 may receive a plurality of uplink physical channels from one or more UEs, including the UE 102.
[0053] In FIG. 1, the one or more channels 106A, 106B are illustrated as an air interface to enable communicative coupling, and can be consistent with cellular communications protocols, such as a UMTS protocol, a 3GPP LTE protocol, an Advanced long term evolution (LTE-A) protocol, a LTE-based access to unlicensed spectrum (LTE-U) , a 5G protocol, a NR protocol, an NR-based access to unlicensed spectrum (NR-U) protocol, and / or any other communications protocol (s) . In implementations, the UE 102 may directly exchange communication data via a ProSe interface. The ProSe interface may alternatively be referred to as a sidelink (SL) interface and may include one or more logical channels, including but not limited to a Physical Sidelink Control Channel (PSCCH) , a Physical Sidelink Discovery Channel (PSDCH) , and a Physical Sidelink Broadcast Channel (PSBCH) .
[0054] Not-at-Cell-Edge / At-Cell-Center Type Criteria
[0055] In some implementations, CellEdgeEvaluation is a criterion used in Radio Resource Management (RRM) requirements. CellEdgeEvaluation enables a UE (e.g., UE 102 of FIG. 1 or UE 1200 of FIG. 12) to determine whether the UE is at an edge of a cell or not. If the UE determines that the UE is not at an edge of a cell, the UE can relax measurements for cell reselection. Relaxed measurements indicate that the UE can reduce measurement frequency, increase time-to-trigger, or use less stringent reselection criteria.
[0056] The measurement relaxation criterion for a UE that is not at a cell edge is satisfied when: (i) Srxlev > S_ {SearchThresholdP} ; or (ii) Srxlev > S_ {SearchThresholdP} and Squal >S_ {SearchThresholdQ} . Srxlev refers to the current Cell Selection RX Level value associated with a serving cell (unit: dB) derived from Reference Signal Received Power (RSRP) measurements) , indicating if a cell’s signal strength is sufficient for selection or reselection. Squal refers to the current Cell Selection Quality value associated with the serving cell (unit: dB) derived from Reference Signal Received Quality (RSRQ) measurements, indicating the quality of a received radio signal.
[0057] When the UE is at a cell edge, the uplink transmission (Tx) power is the maximum, resulting in the maximum Tx-into-Rx interference. By contrast, when the UE is close to a cell center, the network (e.g., the base station) configures a threshold for disabling scheduling restrictions. In some examples, the network disables scheduling restrictions when Srxlev > X (where X is a threshold power level value) . In some examples, the network disables scheduling restrictions when Srxlev > X and Squal > Y (where Y is a threshold signal quality value) . Scheduling restrictions refer to constraints on resource allocation in UL transmission and downlink (DL) reception, impacting how efficiently the network assigns resources to UE. Scheduling restrictions can include, e.g., time-domain (slot-based) restrictions and frequency-domain (resource block) restrictions, etc.
[0058] FIG. 2 illustrates an example process for managing scheduling restrictions according to some implementations. The process 200 is described as being performed by a UE, such as UE 102 of FIG. 1 or UE 1200 of FIG. 12. The example process 200 shown in FIG. 2 can be modified or reconfigured to include additional, fewer, or different steps (not shown in FIG. 2) , which can be performed in the order shown or in a different order.
[0059] At 202, the UE receives, from a base station (e.g., base station 104 of FIG. 1 or base station 1300 of FIG. 13) , a signal including a power level threshold value (e.g., X) . The signal can be an RRC signal, a MAC CE signal, a DCI signal, or a System Information Block (SIB) signal.
[0060] At 204, the UE determines that a measured Srxlev of a serving cell of the UE is greater than the power level threshold value (e.g., X) and reports the determination to the base station.
[0061] At 206, the UE receives, from the base station, a second signal instructing the UE to disable scheduling restrictions based at least on determining that the measured Srxlev of a serving cell is greater than the power level threshold value (e.g., X) . The second signal can also be an RRC signal, a MAC CE signal, a DCI signal, or a SIB signal.
[0062] FIG. 3 illustrates another example process for managing scheduling restrictions according to some implementations. The process 300 is described as being performed by a base station, such as base station 104 of FIG. 1 or base station 1300 of FIG. 13. The example process 300 shown in FIG. 3 can be modified or reconfigured to include additional, fewer, or different steps (not shown in FIG. 3) , which can be performed in the order shown or in a different order.
[0063] At 302, the base station sends a signal to a UE (e.g., UE 102 of FIG. 1 or UE 1200 of FIG. 12) , the signal including a power level threshold value (e.g., X) . The signal can be an RRC signal, a MAC CE signal, a DCI signal, or a SIB signal.
[0064] At 304, the base station disables scheduling restrictions based at least on determining that a measured Srxlev of a serving cell is greater than the power level threshold value (e.g., X) . The base station disables scheduling restrictions if the measured Srxlev of a serving cell for the UE is greater than the power level threshold value (e.g., X) .
[0065] FIG. 4 illustrates another example process or managing scheduling restrictions according to some implementations. The process 400 is described as being performed by a UE, such as UE 102 of FIG. 1 or UE 1200 of FIG. 12. The example process 400 shown in FIG. 4 can be modified or reconfigured to include additional, fewer, or different steps (not shown in FIG. 4) , which can be performed in the order shown or in a different order.
[0066] At 402, the UE receives, from a base station (e.g., base station 104 of FIG. 1 or base station 1300 of FIG. 13) , a signal including a power level threshold value (e.g., X) and a signal quality threshold value (e.g., Y) . The signal can be an RRC signal, a MAC CE signal, a DCI signal, or a SIB signal.
[0067] At 404, the UE determines that a measured Srxlev of a serving cell of the UE is greater than the power level threshold value (e.g., X) and a measured Squal of the serving cell is greater than the signal quality threshold value (e.g., Y) , and reports the determination to the base station.
[0068] At 406, the UE receives, from the base station, a second signal instructing the UE to disable scheduling restrictions based at least on determining that a measured Srxlev of a serving cell is greater than a power level threshold (e.g., X) and a measured Squal of the serving cell is greater than the signal quality threshold value (e.g., Y) .
[0069] FIG. 5 illustrates another example process for managing scheduling restrictions according to some implementations. The process 500 is described as being performed by a base station, such as base station 104 of FIG. 1 or base station 1300 of FIG. 13. The example process 500 shown in FIG. 5 can be modified or reconfigured to include additional, fewer, or different steps (not shown in FIG. 5) , which can be performed in the order shown or in a different order.
[0070] At 502, the base station sends a signal to a UE (e.g., UE 102 of FIG. 1 or UE 1200 of FIG. 12) , the signal including a power level threshold value (e.g., X) and a signal quality threshold value (e.g., Y) . The signal can be an RRC signal, a MAC CE signal, a DCI signal, or a SIB signal.
[0071] At 504, the base station disables scheduling restrictions based at least on determining that a measured Srxlev of a serving cell is greater than the power level threshold (e.g., X) and a measured Squal of the serving cell is greater than the signal quality threshold value (e.g., Y) .
[0072] UL Power Headroom Report
[0073] UL power headroom information can be used by MAC CEs to assist the network in managing power control and optimizing the balance between power efficiency and transmission quality. The UL power headroom value indicates a difference between the maximum UL transmission power the UE can achieve and the actual power being used for UL transmission. The UL power headroom information can be determined using the following equation: UL Power Headroom = UE Maximum UL Transmission Power -PUSCH power = Pmax -Ptx (Actual UL transmission power of the UE) .
[0074] In some implementations, the network dynamically restricts DL scheduling based on the UL power headroom report. For example, the UE is not expected to receive DL scheduling if UL Power Headroom < Z (where Z is a threshold power level value) .
[0075] FIG. 6 illustrates an example process for managing scheduling restrictions according to some implementations. The process 600 is described as being performed by a UE, such as UE 102 of FIG. 1 or UE 1200 of FIG. 12. The example process 600 shown in FIG. 6 can be modified or reconfigured to include additional, fewer, or different steps (not shown in FIG. 6) , which can be performed in the order shown or in a different order.
[0076] At 602, the UE generates a UL power headroom report including a UL power headroom value.
[0077] At 604, the UE transmits the UL power headroom report to a base station (e.g., base station 104 of FIG. 1 or base station 1300 of FIG. 13) .
[0078] At 606, the UE receives, from the base station, a signal to dynamically restrict DL scheduling based on the UL power headroom report. The signal can be an RRC signal, a MAC CE signal, a DCI signal, or a SIB signal. Using dynamic DL scheduling restriction, the base station can apply temporary or adaptive limitations on the downlink data transmission for a particular UE or a group of UEs. The dynamic DL scheduling restriction can change in real time based on network conditions, traffic load, or radio resource management strategies.
[0079] FIG. 7 illustrates another example process for managing scheduling restrictions according to some implementations. The process 700 is described as being performed by a base station, such as base station 104 of FIG. 1 or base station 1300 of FIG. 13. The example process 700 shown in FIG. 7 can be modified or reconfigured to include additional, fewer, or different steps (not shown in FIG. 7) , which can be performed in the order shown or in a different order.
[0080] At 702, the base station receives, from a UE (e.g., UE 102 of FIG. 1 or UE 1200 of FIG. 12) , a UL power headroom report including a UL power headroom value.
[0081] At 704, the base station dynamically restricts DL scheduling based on the UL power headroom report.
[0082] Applicability of Not-at-Cell-Edge / At-Cell-Center Type Criteria and UL Power Headroom Report
[0083] In some implementations, the UE can use a DCI message (DCI by DCI basis) to determine whether to restrict scheduling according to the previous criteria (Not-at-Cell-Edge / At-Cell-Center Type Criteria or UL Power Headroom Report) . Each DCI message is processed individually to determine whether to restrict DL scheduling. In some implementations, a predetermined duration (e.g., the number of slots / an amount of time) during which DL scheduling restriction is enabled / disabled can be signaled by (i) RRC Reconfiguration; (ii) dynamic MAC CEs or semi-static MAC CEs; or (iii) dynamic DCI. Semi-static MAC CEs are configured through higher-layer signaling RRC and do not change as frequently as dynamic MAC CEs. Dynamic DCI refers to DCI that is transmitted and updated on a per-slot basis by a base station (e.g., gNB or eNB) to dynamically schedule UEs for uplink and downlink transmissions.
[0084] In some implementations, the RRC reconfiguration signal, the dynamic or semi-static MAC CE, or the dynamic DCI message includes the predetermined duration. In some examples, scheduling restrictions are enabled by default, and the base station can dynamically disable scheduling restrictions within the predetermined duration. In some examples, scheduling restrictions are disabled by default, and the base station can dynamically enable scheduling restrictions within the predetermined duration.
[0085] Collision with Other Downlink Channels
[0086] Some downlink channels may be considered to be more important than other downlink channels. For example, in some cases, PDCCH has a higher priority than Physical Downlink Shared Channel (PDSCH) . PDSCH can also recover via Hybrid Automatic Repeat Request (HARQ) , while PDCCH does not have a recovery mechanism. For example, Physical Broadcast Channel (PBCH) and Channel State Information Reference Signal (CSI-RS) play different roles.
[0087] In some implementations, the network allows simultaneous transmission (Tx) and reception (Rx) regardless of colliding DL channels. For example, no matter whether PDCCH, PDSCH, PBCH, or CSI-RS collide with each other or not, the network allows simultaneous Tx and Rx. Colliding DL channels refer to situations where two or more downlink physical channels or signals are scheduled or transmitted over the same time-frequency resources (overlapping frequency bands and / or time slots) , leading to interference or transmission failures.
[0088] In some implementations, the network allows simultaneous Tx-Rx only if higher-priority DL channels are not colliding. In some examples, the network allows simultaneous Tx-Rx only outside the PDCCH control region. The PDCCH control region refers to the time-frequency area within a slot where PDCCH is transmitted. In some examples, the network allows simultaneous Tx-Rx only outside the SSB / PBCH region. The SSB / PBCH region refers to the time-frequency resources within a radio frame where SSB and PBCH are transmitted. In some examples, the network allows simultaneous Tx-Rx only outside a region allocated for another higher-priority DL channel region.
