Abstract

Methods, systems, and devices for wireless communication are described. A user equipment (UE) can communicate with a network entity within a first coverage area associated with a first wireless cell. The UE can receive a system information (SI) update indication indicating that a first coverage area is modified to a second coverage area. The SI update indication can also include one or more thresholds, the UE can use the one or more thresholds to determine whether the UE will receive an updated SI message associated with modifying the first coverage area to the second coverage area, or whether the UE will skip receiving the updated SI message associated with modifying the first coverage area to the second coverage area. The UE then determines whether to receive the updated SI message based on the one or more thresholds.

[0002] This patent application claims priority to U.S. patent application No. 17 / 847,574, entitled “COVERAGE ADAPTATION AND IMPACT ON IDLE USER EQUIPMENT (UE)” filed by Abedini et al. on June 23, 2022, which is assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field

[0003] The following relates to wireless communications including coverage adaptation and impact on idle user equipment (UE). Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each of which supports wireless communication for a communication device, which may be referred to as a user equipment (UE).

[0005] Some network equipment in a wireless communication system may support various power saving modes to reduce overall system energy consumption while maintaining reliable communications with UEs. Summary of the invention

For example, the described technology supports increased power savings in wireless communication systems. In some examples, one or more inactive or idle UEs located in a first coverage area may be affected by a change in the coverage area performed by a network entity. In such cases, one or more UEs may wake up to receive a system information update indication and associated updated system information that notifies the UE of the change in coverage area. However, in some cases, the UE may not be affected by the coverage change and may determine to skip receiving updated system information based on evaluating one or more thresholds included in the system information update indication. In some other examples, the system information update indication may include additional information for notifying the UE of cell selection and reselection details, coverage change timing information, or a combination thereof.

[0051] In some wireless communication systems, the coverage area served by one or more network entities may be modified or adapted to accommodate various network energy saving modes. For example, a first network entity may serve one or more user equipments (UEs) within a first geographic coverage area (e.g., a coverage area) and may be adjacent to one or more neighboring network entities (e.g., each neighboring network entity serves UEs within a corresponding geographic coverage area). In some examples, one or more of the network entities may reduce (e.g., deactivate) their corresponding geographic coverage areas to support network energy saving, and the first network entity may increase the first geographic coverage area to compensate for possible coverage loss associated with the one or more reduced coverage areas. Additionally or alternatively, the first network entity may reduce (e.g., deactivate) the first geographic coverage area to support network energy saving, and one or more of the neighboring network entities may increase their corresponding geographic coverage areas to compensate for possible coverage loss associated with the reduced first geographic coverage area.

[0052] When a coverage area (such as a geographic coverage area or a radio cell) changes (e.g., is reduced to support network energy conservation or is increased to compensate for the reduced coverage area), the network entity may perform a handover procedure for one or more UEs affected by the coverage change. For example, some UEs may be located in an area initially served by a first network entity (e.g., which has reduced the corresponding coverage area to support network energy conservation) and will instead be served by a second network entity (e.g., which has increased the corresponding coverage area to compensate for one or more reduced coverage areas) for subsequent communications. In order to avoid coverage loss for these UEs that experience a coverage change, the first network entity may indicate to the second network entity that the UE (e.g., located in an area that will no longer be within the reduced coverage area) will be served by the second network entity for subsequent communications.

[0053] In some cases, one or more UEs experiencing a coverage area change may be in an idle or inactive state, and a network entity may send a system information (SI) update that may wake up all corresponding UEs served by the network entity. The SI update may indicate a change to one or more communication parameters (e.g., synchronization signal block (SSB) transmit power, access control information, SS threshold for random access channel (RACH) transmission, cell selection criteria, cell reselection criteria, or any combination thereof), and each UE may receive the one or more communication parameters in response to the change in coverage area. However, waking up to receive the SI update may result in unnecessary power consumption of one or more of the receiving UEs. For example, one or more of the receiving UEs in an idle or inactive state may still be located within a reduced coverage area and may therefore not be affected by the coverage change. In such cases, reacquiring SI may result in unnecessary power consumption because the UE uses power to wake up to receive the SI update.

[0054] Additionally or alternatively, one or more of the UEs may perform cell reselection (e.g., be handed over to a second network entity) due to a coverage change, and may incur additional latency and power consumption costs to reacquire updated SI (e.g., perform additional measurements due to low mobility, re-evaluate detected or measured cells for reselection, and perform reselection). In addition, the timing of the coverage area reduction may be ambiguous, and the first network entity may reduce the coverage area before all reselecting UEs reacquire updated SI. Therefore, techniques that support optimizing UEs' reactions to receiving SI updates can reduce overall power consumption and improve user experience.

[0055] In some examples, the wireless communication system may support one or more techniques for improving the efficiency of receiving SI updates. In some cases, the network entity may include additional information in the SI update indication, and the idle or inactive UE may use the additional information to determine whether to wake up to receive the updated SI, or whether to skip receiving the updated SI. For example, the extended SI update may indicate which UEs will reacquire SI (e.g., based on corresponding SS-RSRP measurements), parameters related to cell selection and reselection, indications that the coverage area is changing, or any combination thereof. Additionally or alternatively, in order to reduce the power consumption of one or more UEs that will perform reselection (e.g., no longer located in a reduced coverage area), the SI update may indicate a list of candidate neighboring network entities that can be used for reselection. For example, the list of candidate neighboring network entities may be preconfigured or may depend on one or more UE parameters (e.g., beam direction). In some cases, the SI indication may provide parameters for candidate neighboring network entities (e.g., updated SSB transmit power, new thresholds, etc.), updated whitelists and blacklists of neighboring wireless cells, or both. In addition, the SI update indication may be extended to provide timing information about changes or transitions at the network entity. For example, the Update SI indication may inform the UE when a network entity will change (e.g., turn off coverage, bar access, change coverage, change transmit power, etc.) and may include information about power ramping (e.g., if such changes are gradual).

[0056] Aspects of the disclosure are first described in the context of a wireless communication system. Aspects of the disclosure are further described with respect to a wireless communication system illustrating network entities and process flow diagrams for modifying associated coverage areas. Aspects of the disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams related to coverage adaptation and impact on idle UEs.

[0057] Figure 1 An example of a wireless communication system 100 supporting coverage adaptation and impact on idle UEs according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating according to other systems and radio technologies (including future systems and radio technologies not explicitly mentioned herein).

[0058] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other nomenclature. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0059] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communication with various types of devices (such as Figure 1 Communicate with other UEs 115 or network entities 105) as shown.

[0060] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.

[0061] In some examples, the network entities 105 may communicate with the core network 130, or with each other, or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, the network entities 105 may communicate with each other directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130) via the backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, the network entities 105 may communicate with each other via midhaul communication links 162 (e.g., according to a midhaul interface protocol) or fronthaul communication links 168 (e.g., according to a fronthaul interface protocol) or any combination thereof. The backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0062] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a home Node B, a home evolved Node B, or other suitable terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, stand-alone) base station architecture, which may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0063] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0064] The functional split between CU 160, DU 165, and RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DUs 165 and RUs 170, such that the DUs 165 may support one or more layers of the protocol stack, and the RUs 170 may support one or more different layers of the protocol stack. The DUs 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by different ones of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on interfaces (eg, channels) between layers of a protocol stack supported by respective network entities 105 that communicate via those communication links.

[0065] In some wireless communication systems (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DUs 165 or one or more RUs 170 may be controlled in part by one or more CUs 160 associated with a donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB donor. The IAB-MT may include a collection of independent antennas for relaying communications with the UE 115, or may share the same antenna of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0066] For example, an access network (AN) or RAN may include an access node (e.g., an IAB donor), communications between an IAB node 104, and one or more UEs 115. The IAB donor may facilitate a connection between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, the IAB donor may refer to a RAN node having a wired or wireless connection to the core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170), wherein the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB donor and the IAB node 104 may communicate via an F1 interface according to a protocol defining a signaling message (e.g., an F1 AP protocol). Additionally or alternatively, CU 160 may communicate with the core network via an interface (which may be an example of a portion of a backhaul link) and may communicate with other CUs 160 (e.g., CU 160 associated with an alternative IAB donor) via an Xn-C interface (which may be an example of a portion of a backhaul link).

[0067] An IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UE 115, wireless self-backhaul capabilities, etc.). DU 165 may act as a distributed scheduling node toward child nodes associated with IAB node 104, and IAB-MT may act as a scheduled node toward a parent node associated with IAB node 104. That is, an IAB donor may be referred to as a parent node that communicates with one or more child nodes (e.g., an IAB donor may relay for UE transmissions through one or more other IAB nodes 104). Additionally or alternatively, depending on the relay chain or configuration of the AN, an IAB node 104 may also be referred to as a parent node or child node of other IAB nodes 104. Thus, the IAB-MT entity of the IAB node 104 may provide a Uu interface for the child IAB node 104 to receive signaling from the parent IAB node 104 , and a DU interface (eg, DU 165 ) may provide a Uu interface for the parent IAB node 104 to signal to the child IAB node 104 or the UE 115 .

[0068] For example, the IAB node 104 may be referred to as a parent node supporting communications for a child IAB node or as a child IAB node associated with an IAB donor, or both. The IAB donor may include a CU 160 having a wired or wireless connection (e.g., backhaul communication link 120) to the core network 130, and may act as a parent node of the IAB node 104. For example, the DU 165 of the IAB donor may relay transmissions to the UE 115 via the IAB node 104, or may directly signal the transmissions to the UE 115, or both. The CU 160 of the IAB donor may signal the establishment of a communication link to the IAB node 104 via the F1 interface, and the IAB node 104 may schedule transmissions (e.g., transmissions relayed from the IAB donor to the UE 115) via the DU 165. That is, data may be relayed to and from the IAB node 104 via signaling via the NR Uu interface of the MT to the IAB node 104. Communications with the IAB node 104 may be scheduled by the DU 165 of the IAB donor, and communications with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104 .

[0069] Where the techniques described herein are applied to the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support coverage adaptation and impact on idle UEs as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0070] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0071] The UE 115 described herein may be capable of communicating with various types of devices such as other UEs 115 which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0072] The UE 115 and the network entity 105 may use resources associated with one or more carriers to wirelessly communicate with each other via one or more communication links 125 (e.g., access links). The term "carrier" may refer to a collection of RF spectrum resources having a physical layer structure defined to support the communication link 125. For example, a carrier for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between a device and any portion (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send," "receive," or "communicate" when referring to the network entity 105 may refer to any portion of a network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0073] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be identified based on a channel raster for discovery by UE 115. A carrier may operate in a standalone mode, in which case initial acquisition and connection may be performed by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which case the connection is anchored using a different carrier (e.g., a different carrier of the same or different radio access technology).

[0074] The communication link 125 shown in the wireless communication system 100 may include downlink transmissions (e.g., forward link transmissions) from the network entity 105 to the UE 115, uplink transmissions (e.g., return link transmissions) from the UE 115 to the network entity 105, or both, among other transmission configurations. A carrier may carry either downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry both downlink communications and uplink communications (e.g., in TDD mode).

[0075] A carrier may be associated with a particular bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz) of a carrier of a particular radio access technology. A device (e.g., a network entity 105, a UE 115, or both) of the wireless communication system 100 may have a hardware configuration that supports communications using a particular carrier bandwidth, or may be capable of being configured to support communications using one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a network entity 105 or a UE 115 that supports concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., a subband, a BWP) or all of a carrier bandwidth.

[0076] The signal waveform transmitted via the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system using MCM techniques, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and the subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), so that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high order modulation scheme may correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0077] One or more parameter sets for a carrier may be supported, and the parameter sets may include subcarrier spacing (Δf) and cyclic prefixes. A carrier may be divided into one or more BWPs with the same or different parameter sets. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications of a UE 115 may be constrained to one or more active BWPs.

[0078] The time interval for the network entity 105 or the UE 115 may be expressed in multiples of a basic time unit, which may be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, where Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. The time intervals of the communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0079] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of micro time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0080] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0081] Physical channels may be multiplexed according to various techniques in order to communicate using a carrier. For example, physical control channels and physical data channels may be multiplexed using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique to signal via a downlink carrier. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth of a carrier or a subset of that system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE 115 may monitor or search a control region to obtain control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to a plurality of UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0082] The network entity 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with the network entity 105 (e.g., using a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other identifier) ​​used to distinguish adjacent cells. In some examples, a cell may also refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) on which the logical communication entity operates. Depending on various factors such as the capabilities of the network entity 105, such cells may range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or may include a building, a subset of a building, or an external space between or overlapping coverage areas 110, and the like.

[0083] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have service subscriptions with a network provider that supports the macro cell. A small cell may be associated with a lower power network entity 105 (e.g., a lower power base station 140) (compared to a macro cell), and the small cell may operate using the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with a small cell (e.g., a UE 115 in a closed subscriber group (CSG), a UE 115 associated with a user in a home or office). A network entity 105 may support one or more cells, and may also support communications via one or more cells using one or more component carriers.

[0084] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0085] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0086] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) may have similar frame timing, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, the network entities 105 may have different frame timing, and in some examples, transmissions from different network entities 105 may not be aligned in time. The techniques described herein may be used for synchronous or asynchronous operation.

[0087] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but does not transmit and receive concurrently). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for UEs 115 include entering a power saving deep sleep mode when not engaged in active communications, operating using limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a subcarrier or resource block (RB) set) within a carrier, within a guard band of a carrier, or outside a carrier.

[0088] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC). UE 115 can be designed to support ultra-reliable, low-latency or critical functions. Ultra-reliable communication may include private communication or group communication, and may be supported by one or more services (such as push-to-talk, video or data). Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency and ultra-reliable low-latency may be used interchangeably herein.

[0089] In some examples, the UE 115 may be configured to support communication directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group that are performing D2D communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 in such a group may be outside of the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.

[0090] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these items. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in the V2X system can communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170) using vehicle-to-network (V2N) communication, or both.

[0091] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity for managing access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity for routing packets or interconnecting to an external network (e.g., a serving gateway (S-GW)), a packet data network (PDN) gateway (P-GW) or a user plane function (UPF)). The control plane entity may manage non-access layer (NAS) functions such as mobility, authentication, and bearer management of UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP service 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0092] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). In general, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range is about one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves may be sufficient to penetrate structures so that macro cells provide service to UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than communications using the lower frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0093] The wireless communication system 100 may also operate using a super high frequency (SHF) region, which may be in the range of 3 GHz to 30 GHz (also known as a centimeter band), or an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as a millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the network entity 105 (e.g., base station 140, RU 170), and the EHF antennas of the corresponding devices may be smaller and closer together than UHF antennas. In some examples, such techniques may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be affected by even greater attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the use of frequency bands specified across these frequency regions may vary by country or regulatory agency.

[0094] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology. When operating using unlicensed RF spectrum bands, devices such as network entity 105 and UE 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations performed using unlicensed bands may be based on carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating using licensed bands. Operations performed using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0095] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas, which can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0096] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals conveyed via antenna elements of an antenna array so that some signals propagating in a particular direction relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0097] The network entity 105 or UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the network entity 105 along different directions. For example, the network entity 105 may send signals according to different sets of beamforming weights associated with different transmission directions. Transmissions along different beam directions may be used to identify (e.g., by a transmitting device (such as network entity 105), or by a receiving device (such as UE 115)) beam directions for later transmission or reception by the network entity 105.

[0098] Some signals, such as data signals associated with a particular receiving device, may be sent by a transmitting device (e.g., transmitting network entity 105, transmitting UE 115) along a single beam direction (e.g., a direction associated with a receiving device (such as receiving network entity 105 or receiving UE 115)). In some examples, a beam direction associated with transmission along a single beam direction may be determined based on signals sent along one or more beam directions. For example, UE 115 may receive one or more of the signals sent by network entity 105 along different directions, and may report to network entity 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0099] In some examples, transmission by a device (e.g., by network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more subbands. Network entity 105 may send a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may be precoded or non-precoded. UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel codebook, a linear combination codebook, a port selection codebook). Although these techniques are described with reference to signals sent along one or more directions by a network entity 105 (e.g., base station 140, RU 170), UE 115 may use similar techniques to send signals multiple times along different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to send signals along a single direction (e.g., to send data to a receiving device).

[0100] A receiving device (e.g., UE 115) may perform receiving operations according to multiple receiving configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a receiving device (e.g., network entity 105). For example, the receiving device may perform reception according to multiple receiving directions by: receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receiving beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receiving beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0101] In some wireless communication systems (e.g., wireless communication system 100), a first network entity 105 may modify a first associated coverage area to support network energy conservation (e.g., reduce the first coverage area) or compensate for a neighboring network entity 105 that has reduced a corresponding coverage area (e.g., expand the first coverage area). In some cases, one or more inactive or idle UEs 115 located within the modified coverage area may be awakened to receive a system information update indication that notifies the inactive or idle UEs 115 of the change in coverage area. In some cases, one or more of the inactive or idle UEs 115 may not be affected by the coverage change (e.g., remain within the adjusted coverage area) and may not need to use wake-up to receive updated system information. Additionally or alternatively, one or more of the inactive or idle UEs that will perform reselection (e.g., perform future communications with the second network entity 105) may perform additional measurements to select the correct second network entity 105, thereby consuming unnecessary power.

[0102] In some cases, the first network entity 105 may send an updated system information update indication to provide more information to the inactive or idle UE 115, which the UE 115 may use to determine whether the UE 115 will wake up to receive the updated system information message, or whether the UE 115 can ignore the updated system information message. For example, the system information update indication may be extended to indicate one or more SS-RSRP thresholds associated with the modified coverage area. In addition, the system information update indication may schedule a PDSCH that notifies the UE 115 of candidate cells that may be used for reselection. Additionally or alternatively, the system information update indication may provide the UE 115 with timing information related to the change to the coverage area associated with the first network entity 105.

[0103] Figure 2 An example of a wireless communication system 200 that supports coverage adaptation and impact on idle UEs according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. For example, the wireless communication system 200 may include one or more network entities 105 (e.g., network entity 105-a and network entity 105-b) and one or more UEs (e.g., UE 115-a and UE 115-b), which can be respectively as described in reference Figure 1Examples of network entities 105 and UEs 115 described herein. In addition, a corresponding geographic coverage area may be associated with each network entity 105 and may be configured by each network entity (e.g., geographic coverage area 215 configured by network entity 105-a and geographic coverage area 220 configured by network entity 105-b). In some examples, network entity 105 may broadcast system information update indication 225 to notify UEs 115 (e.g., UE 115-a and UE 115-b) within the modified geographic coverage area of ​​the system change. Additionally or alternatively, network entity 105 may send an updated system information signal 230 to one or more UEs based on the techniques described herein.

[0104] In some cases, the network entity 105 may configure the size of the associated geographic coverage area (e.g., reduce or expand) to support a network energy conservation mode. For example, the network entity 105-a may identify minimal activity within the network (e.g., during off-peak hours) and may reduce the geographic coverage area 215 (e.g., modify coverage from the geographic coverage area 215-a to the geographic coverage area 215-b) to mitigate energy consumption. In response to the reduction of the geographic coverage area 215, one or more neighboring network entities 105 (e.g., network entity 105-b) may expand the associated geographic coverage area (e.g., geographic coverage area 220) to compensate for areas that were served by the initial geographic coverage area 215-a but are no longer served after the geographic coverage area 215-a is reduced (e.g., reduced to the geographic coverage area 215-b).

[0105] In some examples, the network entity 105-a may configure a first set of antenna arrays (e.g., to support directional beamforming in a first spatial coverage area), and the second network entity 105-b may configure a second set of antenna arrays (e.g., to support directional beamforming in a second spatial coverage area) to support network energy conservation. For example, the first network entity 105-a may reduce the first spatial coverage area to support network energy conservation (e.g., deactivate one or more of the first set of antenna arrays), and the second network entity 105-b may increase the second spatial coverage area to compensate for the reduced first spatial coverage area (e.g., activate one or more deactivated antenna arrays).

[0106] In some examples, the network entity 105 that changes the operation mode (e.g., enters a power saving mode, enters a compensation mode, returns to normal operation, etc.) can change one or more system parameters. For example, changing the operation mode can change a synchronization signal (SS) block (SSB) (e.g., carried in a system information (SI) block 1 (SIB1)), access control related information carried in a master information block (MIB) or SIB1 (e.g., whether a cell is barred), an SS threshold for random access procedure (RACH) transmission (e.g., carried in SIB1), a cell selection criterion carried in SIB1 (e.g., a received power threshold and a quality threshold), a cell reselection criterion (e.g., a threshold of candidate cells carried in any one of SIB2, SIB3, or SIB4, a white list, a black list, etc.), or any combination thereof. When the first network entity 105 (e.g., network entity 105-a) changes the operation mode, one or more neighboring network entities 105 (e.g., network entity 105-b) can update the contents of the associated SIB2, SIB3, SIB4, or any combination thereof.

[0107] When the geographic coverage area 215 is reduced, the network entity 105-a may perform handover procedures for one or more UEs 115. For example, the network entity 105-b may determine that the UE 115 (e.g., UE 115-b) will no longer be located within the reduced geographic coverage area 215-b, and may indicate to the neighboring network entity 105 (e.g., network entity 105-b) that the UE 115 will perform subsequent communications with the neighboring network entity 105. In some cases, one or more UEs 115 located within the initial geographic coverage area 215-a may be in an inactive or idle state. In this case, the network entity 105-a may not be aware of one or more of the inactive UEs 115, and therefore may not perform the necessary handover procedures for the inactive UEs 115 (e.g., UE 115-b) that are no longer located within the reduced coverage area 215-b. Thus, the network entity 105-a and the neighboring network entity 105 (e.g., the network entity 105-b) may broadcast a system information update indication 225 that notifies and wakes up (e.g., for inactive or idle UEs 115) all UEs 115 within the corresponding geographic coverage area of ​​an upcoming updated system information signal 230 that includes updated system information based on the coverage change. However, in some cases, one or more inactive or idle UEs 115 that will not change coverage (e.g., UEs 115-a that remain within the reduced geographic coverage area 215-b) may still wake up in response to the system information update indication 225, thereby resulting in unnecessary power consumption.

[0108] In some cases, based on the updated system information, one or more UEs 115 that will perform a reselection procedure (e.g., UEs 115-b that no longer remain within the reduced geographic coverage area 215-b) may perform additional measurements to reacquire the updated system information signal 230 (e.g., if the low-mobility UEs 115 performed relaxed neighbor cell measurements before the geographic coverage area 215 changed), and may therefore experience relatively significant latency and power consumption. Additionally or alternatively, the network entity 105-a may reduce the geographic coverage area 215 before all UEs 115 in the initial geographic coverage area 215-a have reacquired the updated system information signal 230, which may leave one or more of the UEs 115 without adequate coverage. Additionally or alternatively, similar principles may be applied to a mobile cell or mobile relay (such as a mobile integrated access and backhaul (IAB) node), which may reduce (e.g., make it smaller or deactivate) an associated coverage area when in close proximity to a stationary cell node or another mobile cell node (e.g., network entity 105-a).

[0109] In some cases, the network entity 105-a may expand the system information update indication 225 to include more information so that one or more inactive or idle UEs 115 (e.g., UE 115-a) that will not change coverage can determine whether to receive an updated system information message. In some other examples, if the inactive or idle UEs 115 that remain within the reduced geographic coverage area 215-b are associated with different beam directions, the network entity 105-a may configure the system information update indication 225 to be transmitted in a relevant direction (e.g., away from the beam direction associated with the UE 115 that should not reacquire the updated system information signal 225).

[0110] Additionally or alternatively, the network entity 105-a may identify that inactive or idle UEs 115 are associated with different coverage distances (e.g., different reference signal received power (RSRP) thresholds), and the system information update indication 225 may be extended to provide an indication of which UEs 115 are to reacquire updated system information signals 230 (e.g., based on synchronization signal (SS) RSRP measured at each of the UEs 115). For example, the network entity 105-a may provide a mapping associating respective SS-RSRP thresholds with one or more geographic coverage areas (e.g., geographic coverage area 215, geographic coverage area 220, or both) via the extended system information update indication 225. In some cases, the SS-RSRP mapping may be indicated via a reserved bit in the system information update indication 225 (e.g., a short message in the downlink control information (DCI)) or via a semi-static indication (e.g., SIB1 that maps bits to different RSRP thresholds, different geographic coverage areas, or both). Additionally or alternatively, the indication may be signaled by a Paging Early Indication (PEI) Physical Downlink Control Channel (PDCCH).

[0111] In some cases, UEs 115 (e.g., UE 115-a and UE 115-b) located within the initial geographic coverage area 215-a may measure the respective SS-RSRP and compare the measured values ​​to the indicated thresholds. For example, UE 115-a may be located at a first distance 205 from the network entity, and UE 115-b may be located at a second distance 210 from the network entity, the first distance 205 being shorter than the second distance 210. Thus, the SS-RSRP measured by UE 115-a may be higher than the SS-RSRP threshold indicated by the system information update indication 225, and the SS-RSRP measured by UE 115-b may be lower than the SS-RSRP threshold indicated by the system information update indication 225. In this case, UE 115-a may determine to skip receiving the upcoming updated system information signal 230 and return to an inactive or idle state to support power conservation based on measuring the SS-RSRP above an indicated threshold mapped to the geographic coverage area 215, and UE 115-b may determine to receive the upcoming updated system information signal 230 based on measuring the SS-RSRP below an indicated threshold mapped to the geographic coverage area 215, as shown. Figure 2 exemplified.

[0112] Additionally or alternatively, the network entity 105-a may configure one or more target groups based on RSRP thresholds. For example, the network entity 105-a may indicate that UE 115-a is part of a group of UEs 115 that skip receiving updated system information signals 230 based on the SS-RSRP measured at UE 115-a being above a threshold mapped to the geographic coverage area 215, and that UE 115-b is part of a group of UEs 115 that receive updated system information signals 230 based on the SS-RSRP measured at UE 115-b being below a threshold mapped to the geographic coverage area 215. In addition, the target group may be based on a mobility state associated with each UE 115 (e.g., a high mobility UE 115 group, a low mobility UE 115 group, or both). In some examples, the network entity 105-a may schedule a physical downlink shared channel (PDSCH) via a PDCCH (e.g., carrying a system information update indication 225). The scheduled PDSCH may carry information indicating which UEs 115 (eg, within geographic coverage area 215) are to reacquire updated system information signals 230 based on associated RSRP thresholds.

[0113] In some other cases, the network entity 105-a may extend the system information update indication 225 to indicate that the system change is related to cell selection parameters, cell reselection parameters, or both (e.g., indicating that the UE 115 that will not perform cell selection or cell reselection can skip receiving the updated system information signal 230). Additionally or alternatively, the network entity 105-a may extend the system information update indication 225 to indicate that the network entity 105-a will change the operating mode (e.g., deactivate, reduce the associated geographic coverage area 215, expand the associated geographic coverage area 215, or otherwise change the coverage area). In this case, the network entity 105-a may send a semi-static indication (e.g., via system information or dedicated radio resource control (RRC) signaling) of one or more configurations associated with different operating modes (e.g., transmit power, RSRP threshold, etc.) before sending the system information update indication.

[0114] In some examples, one or more UEs 115 may no longer be located in the reduced geographic coverage area 215-b based on the coverage change (e.g., UE 115-b) and may perform a cell reselection procedure to determine a new network entity 105 with which to perform subsequent communications (e.g., network entity 105-b associated with geographic coverage area 220). For example, after receiving system information update indication 225, UE 115-b may determine to receive updated system information signal 230 and perform cell reselection based on the measured SS-RSRP and the RSRP threshold mapped to geographic coverage area 215.

[0115] In order to reduce power consumption and reduce excessive measurements associated with the cell reselection procedure, the network entity 105-a may indicate the updated portion of the updated system information signal 230 directly to the UE 115-b via a PDSCH (e.g., a PDSCH scheduled by the system information update indication 225). For example, the UE 115-b may identify a list of candidate neighboring cells available for reselection by the UE 115-b (e.g., due to a reduction in the geographic coverage area 215) via the PDSCH. The list of candidate neighboring cells may be pre-configured or may be different for different beam directions associated with the UE 115 (e.g., different information transmitted by the PDSCH for different beam directions). In some cases, the PDSCH indication may provide one or more parameters associated with the candidate neighboring cells (e.g., updated SSB transmit power, new thresholds, etc.) to assist the reselection procedure. Additionally or alternatively, an updated whitelist (e.g., cells approved for reselection) or an updated blacklist (e.g., cells not approved for reselection) may be provided by the PDSCH indication.

[0116] In some cases, in order to prevent one or more UEs 115 (e.g., UE 115-b) from losing coverage due to network entity 105-a reducing geographic coverage area 215 before one or more UEs 115 have reacquired updated system information signals 230, one or more UEs 115 may receive timing information about upcoming changes in the system. For example, a PDSCH (e.g., scheduled by a PDCCH carrying a system information update indication 225) may indicate to UE 115-b timing information corresponding to when network entity 105-a will implement a system change or transition to a new mode (e.g., relative timing information or absolute timing information based on a system frame number (SFN)). The system change or transition may be an example of turning off coverage (e.g., deactivating), disabling access, reducing or increasing coverage (e.g., reducing geographic coverage area 215 or expanding geographic coverage area 220), changing associated transmit power, or any combination thereof. In addition, network entity 105-a may scramble the PDSCH via a paging radio network temporary identifier (P-RNTI) or another RNTI defined for the purpose of scrambling the PDSCH. In some cases, the network entity 105-a may gradually perform a change in coverage (e.g., changing an initial geographic coverage area 215-a to a reduced geographic coverage area 215-b) or a change in transmit power. In this case, the PDSCH may be updated to include information related to the power ramp to notify the UE 115-b of the duration of the change.

[0117] Figure 3Examples of wireless network modification configurations 300-a and 300-b that support coverage adaptation and impact on idle UEs according to one or more aspects of the present disclosure are illustrated. For example, the wireless network modification configuration may show various network entities A, B, C, D, E, F, and G, which may be reference Figure 1 and Figure 2 An example of a corresponding network entity 105 is described.

[0118] At 305, the wireless network 300-a may include network entities A through G, each serving a corresponding geographic coverage area or cell within the wireless network 300-a. Network entities B through G may enter a power saving mode and may deactivate at least a portion of their service coverage area. In such an example, network entity A may enter a compensation mode at 310 and may extend its associated coverage area to effectively extend coverage to devices served by network entities B through G during the power saving period.

[0119] At 315, the wireless network 300-b may include network entities A through G, each serving a corresponding geographic coverage area or cell within the wireless network 300-b. Network A may enter a power saving mode and may deactivate at least a portion of its service coverage area. In such an example, network entities B through G may enter a compensation mode at 320 and may extend their associated coverage areas to effectively extend coverage to devices served by network entity A during the power saving period.

[0120] In some cases, one or more inactive or idle wireless devices located within the coverage area may be awakened to receive a system information update indication, thereby notifying the devices of a change in the coverage area in a power saving mode. In some cases, one or more of the inactive or idle UEs may not be affected by the coverage change and may not need to be awakened to receive updated system information. However, in some examples, network entities A to G may send updated system information update indications to provide more information to the inactive or idle devices, which may use this information to determine whether to wake up to receive updated system information or remain in an idle or inactive mode to save power.

[0121] Figure 4 An example of a process flow 400 for supporting coverage adaptation and impact on idle UEs according to one or more aspects of the present disclosure is illustrated. The process flow 400 may be implemented by a network entity 105-c and a UE 115-c, which may be as described with respect to Figure 2An example of a network entity 105-a and a UE 115 (e.g., UE 115-a or UE 115-b) is depicted. In some examples, certain signaling or procedures of process flow 400 may occur in an order different from the order shown. Additionally or alternatively, some additional procedures of signaling may occur, some procedures may occur in an order different from the order shown, or some signaling or procedures may be omitted.

[0122] At 405, the network entity 105-c may communicate with the UE 115-c within a first coverage area associated with the first wireless cell. In some cases, the network entity 105-c may send system information signaling, which may include procedural communications between the network entity 105-c and the UE 115-c prior to a coverage area change performed by the network entity 105-c. The UE 115-c may determine an initial state of the system information via the system information signal.

[0123] At 410, the network entity 105-c may determine to change a coverage area associated with the network entity 105-c. For example, the network entity 105-c may identify low activity or mobility within an associated coverage area (e.g., a geographic coverage area, a spatial coverage area, or both), and may determine to reduce the associated coverage area to support an energy conservation mode. Additionally or alternatively, the network entity 105-c may determine to increase the associated coverage area to compensate for a neighboring network entity 105 reducing an associated coverage area (e.g., to support network energy conservation). The modification to the associated coverage area may indicate a deactivation of at least a portion of the network entity 105-c, an activation of at least a portion of the network entity 105-c, a change in the associated coverage area, or any combination thereof.

[0124] At 415, the network entity 105-c may send a system information update signal to the UE 115-c based on identifying the change in the associated coverage area. For example, the system information update indication may indicate to the UE 115-c that a first coverage area (e.g., within which the UE 115-c is located) is modified to a second coverage area that is different from the first coverage area (e.g., expanded or reduced). In some cases, the network entity 105-c may send the system information update indication in a system information block or via a Paging Early Indication-Physical Downlink Control Channel.

[0125] In some cases, the system information update indication may provide a mapping associating a synchronization signal-reference signal received power (SS-RSRP) threshold with one or more coverage areas. For example, the system information update indication may include one or more bits that map the SS-RSRP threshold to a first coverage area or a second coverage area. In some examples, the mapping may indicate one or more UE groups associated with different SS-RSRP power thresholds, different UE mobility states, or any combination thereof. Additionally or alternatively, the system information update indication may include a timing threshold indicating timing information for a change in the coverage area. For example, the timing threshold may indicate the time at which UE 115-c is scheduled to receive an updated system information signal, the time at which the network entity 105-c restricts access to UE 115-c, enables access to UE 115-c, changes relative transmit power, or any combination thereof. In some cases, the timing threshold may include a relative timing threshold or an absolute timing threshold based on a modification to the coverage area. For example, the timing threshold may be indicated based on a system frame number, which may be compared to an absolute timing or a system relative timing. In addition, the timing threshold may include a timing interval for a transition of the coverage area, which may provide cell coverage transition information, power ramp-up information, or both to be applied during the coverage area transition. The network entity 105-c may communicate the timing threshold via a downlink shared channel scheduled by a downlink control channel, which may be scrambled by a radio network temporary identifier associated with the updated system information signal.

[0126] At 420, the UE 115-c may measure SS-RSRP based on receiving the system information update indication. For example, the UE 115-c may identify an SS-RSRP threshold associated with the initial geographic coverage area and an SS-RSRP threshold associated with the reduced geographic coverage area. Thus, the UE 115-c may measure the SS-RSRP and compare the measured value to one or more thresholds. In some cases, the UE 115-c may determine to skip receiving the upcoming updated system information signal due to the measured SS-RSRP value being higher than the threshold indicated by the system information update indication. Additionally or alternatively, the UE 115-c may determine to receive the upcoming updated system information signal due to the measured SS-RSRP value being lower than the threshold indicated by the system information update indication.

[0127] At 425, the UE 115-c may determine whether to receive an updated system information signal from the network entity 105-c based on one or more thresholds (such as an SS-RSRP threshold) and the associated SS-RSRP measured at the UE 115-c. For example, after the UE 115-c determines to receive an updated system information signal due to measuring an SS-RSRP below a threshold indicated by a system information update indication, the network entity 105-c may send an updated system information signal to the UE 115-c. In some cases, the UE 115-c may identify a list of one or more neighboring network entities 105 that may be used for reselection based on receiving the updated system information signal. For example, an updated portion of the system information may be directly indicated via a downlink shared channel scheduled by the system information update signal. The UE 115-c may then identify a list of candidate neighboring network entities 105 indicated by the system information update signal. Additionally or alternatively, the list of one or more neighboring network entities 105 may indicate a set of restricted cells that cannot be used for reselection by the UE 115-c. In some cases, the list of candidate neighboring network entities 105 may be based on one or more beam directions associated with the network entity 105-c. Additionally or alternatively, the updated system information signal may indicate a change in SS transmit power at the network entity 105-c.

[0128] At 430, the UE 115-c may optionally determine a new coverage area for subsequent communications. For example, if the UE 115-c determines to receive an updated system information signal due to a measured SS-RSRP value below an indicated threshold associated with a reduced geographic coverage area, the UE 115-c may identify a new network entity 105 with which to perform future communications (e.g., from a list of one or more candidate neighboring network entities 105). In some cases, the UE 115-c may not determine a new coverage area due to a determination to skip receiving an updated system information signal (e.g., due to a measured SS-RSRP value above an indicated threshold associated with a reduced geographic coverage area).

[0129] Figure 5 A block diagram 500 of a device 505 supporting coverage adaptation and impact on idle UEs according to one or more aspects of the present disclosure is shown. The device 505 can be an example of aspects of the UE 115 as described herein. The device 505 may include a receiver 510, a transmitter 515, and a communication manager 520. The device 505 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0130] The receiver 510 may provide means for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to coverage adaptation and impact on idle UEs). The information may be passed to other components of the device 505. The receiver 510 may utilize a single antenna or a collection of multiple antennas.

[0131] The transmitter 515 may provide means for transmitting signals generated by other components of the device 505. For example, the transmitter 515 may transmit information associated with various information channels (e.g., control channels related to coverage adaptation and impact on idle UEs, data channels, information channels), such as packets, user data, control information, or any combination thereof. In some examples, the transmitter 515 may be co-located with the receiver 510 in a transceiver module. The transmitter 515 may utilize a single antenna or a collection of multiple antennas.
