Technical Field

[0003] Aspects of the present disclosure generally relate to wireless communications and dynamic signaling techniques for wireless coverage enhancement. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services, such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) that can support communications for multiple user equipment (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or "forward link") refers to a communication link from a BS to a UE, and an "uplink" (or "reverse link") refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at a city, country, region, and even global level. New Radio (NR), which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, better integrating with other open standards, and supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation, wherein the open standards use orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) (CP-OFDM) on the downlink (DL), CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL). As the demand for mobile broadband access continues to grow, further improvements in LTE, NR, and other radio access technologies remain very useful. Summary of the invention

In addition, the scope of the present disclosure is intended to cover such a device or method, which is practiced using other structures, functions, or structures and functions in addition to or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0064] Several aspects of telecommunication systems will now be described with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0065] It should be noted that although terms generally associated with 5G or NR radio access technologies (RATs) may be used herein to describe various aspects, various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs beyond 5G (e.g., 6G).

[0066] Figure 1is a diagram showing an example of a wireless network 100 according to the present disclosure. Among other examples, the wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network. The wireless network 100 may include multiple base stations (BSs) 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0067] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access to UEs with subscribed services. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with subscribed services. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0068] In some aspects, the cells are not necessarily stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0069] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the illustrated example, relay BS 110d may communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, relay base station, relay, or the like.

[0070] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0071] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0072] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be fixed or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biosensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0073] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. For example, MTC UEs and eMTC UEs include robots, drones, remote devices, sensors, meters, monitors and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node may provide a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or provide a connection to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included in a housing that houses components of UE 120 (e.g., processor components and / or memory components). In some aspects, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0074] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0075] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary for communicating with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations performed by base station 110 as described elsewhere herein.

[0076] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1) from 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2) from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz" band. Similarly, FR2 is also often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) determined by the International Telecommunication Union (ITU) as a "millimeter wave" band. Therefore, unless otherwise stated, it should be understood that the term "sub-6 GHz" and the like (if used herein) can broadly represent frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise stated, it should be understood that the term "millimeter wave" and the like, if used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0077] As mentioned above, Figure 1 is provided as an example. Other examples may be related to Figure 1 Described differently.

[0078] Figure 2 2 is a diagram illustrating an example 200 of a base station 110 and a UE 120 in communication in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where, in general, T≥1 and R≥1.

[0079] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and / or secondary synchronization signals (SSS)). If applicable, a transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and may provide T output symbol streams to T modulators (MOD) 232a through 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may also process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0080] At the UE 120, antennas 252a to 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may also process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to the data sink 260, and provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a channel quality indicator (CQI) parameter, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0081] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. For example, the network controller 130 may include one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0082] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included in, one or more antenna panels, antenna groups, antenna element groups, and / or antenna arrays, etc. Antenna panels, antenna groups, antenna element groups, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element groups, and / or antenna arrays may include coplanar antenna element groups and / or non-coplanar antenna element groups. Antenna panels, antenna groups, antenna element groups, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element groups, and / or antenna arrays may include antenna elements coupled to one or more transmitting and / or receiving components (such as Figure 2 One or more antenna elements of one or more components).

[0083] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may also generate reference symbols for one or more reference signals. If applicable, the symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. A processor (e.g., controller / processor 280) and memory 282 may use the transceiver to perform aspects of any of the methods described herein.

[0084] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. A processor (e.g., controller / processor 240) and memory 242 may use the transceiver to perform aspects of any of the methods described herein.

[0085] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the base station 110 may perform one or more techniques associated with dynamic signaling for wireless coverage enhancement, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the can perform or direct e.g. Figure 4 The process of 400 Figure 5 The operations of process 500 and / or other processes described herein may be performed. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of base station 110 and / or UE 120, the one or more instructions may perform or direct, for example, Figure 4 The process of 400 Figure 5 The process 500 and / or other processes described herein may be performed. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions. The scheduler 246 may schedule UEs for data transmission on downlinks and / or uplinks.

[0086] In some aspects, the UE 120 may include means for receiving an indication to activate one or more coverage enhancement parameters in a single dynamic signaling communication, means for activating the one or more coverage enhancement parameters based at least in part on receiving the indication, etc. In some aspects, such means may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0087] In some aspects, the BS 110 may include means for determining to activate one or more coverage enhancement parameters for the one or more UEs 120, means for sending a single dynamic communication indicating activation of the one or more coverage enhancement parameters to the one or more UEs 120 based at least in part on the determination to activate the one or more coverage enhancement parameters, etc. In some aspects, such means may include in conjunction with Figure 2 One or more components of BS 110 are depicted, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0088] As mentioned above, Figure 2 is provided as an example. Other examples may be related to Figure 2 Described differently.

[0089] In a wireless network, a BS and a UE may communicate on a narrow beam, which may be a beam refined from a wide beam associated with the BS (and narrow relative to the wide beam). In some cases, the UE and the BS may communicate on a narrow beam pair, which may include a narrow transmit beam and a narrow receive beam. In these cases, the BS may send downlink communications to the UE using a narrow transmit beam, and may receive uplink communications from the UE using a narrow receive beam. Similarly, the UE may send uplink communications to the BS using a narrow transmit beam, and may receive downlink communications from the BS using a narrow receive beam.

[0090] The beam reliability of narrow beams may affect the coverage of unicast channels, especially in higher bandwidth frequency ranges in 5G NR, such as frequency range 2 (FR2), etc. In some cases, a UE may experience degraded or worsened beam performance on one or more narrow beams (e.g., due to beam blocking, due to partial shadowing, etc.). In addition, other UEs sharing the same narrow beam and / or communicating on another narrow beam related to the narrow beam (e.g., as refined from the same wide beam) may experience similar degradation.

[0091] Some aspects described herein provide techniques and apparatus for dynamic signaling for wireless coverage enhancement. In some aspects, a BS (e.g., BS 110) may be able to signal coverage enhancement parameters to one or more UEs (e.g., UE 120 experiencing degraded or deteriorated beam performance on one or more narrow beams, or UE 120 in other communication scenarios). The BS may signal activation of the coverage enhancement parameters to one or more UEs in a single dynamic signaling communication, and the UEs may activate the coverage enhancement parameters and communicate on one or more narrow beams based at least in part on the coverage enhancement parameters. In this way, a single dynamic signaling communication of the coverage enhancement parameters from the BS allows maintaining or improving the beam performance of one or more narrow beams while indicating the activation to one or more UEs in a manner that saves signaling overhead (which reduces radio resource consumption).

[0092] FIG. 3A to FIG. 3E is a diagram illustrating one or more examples 300 of dynamic signaling for wireless coverage enhancement according to the present disclosure. FIG. 3A to FIG. 3E As shown, example 300 includes BS 110 (eg, as described above in conjunction with Figure 1 and / or Figure 2 The BS 110 shown and described) and one or more UEs 120 (e.g., as described above in conjunction with Figure 1 and / or Figure 2 1 and 120). BS 110 and one or more UEs 120 may be included in a wireless network such as wireless network 100. BS 110 and one or more UEs 120 may communicate over a wireless access link, which may include an uplink and a downlink. FIG. 3A to FIG. 3E The example 300 including UE1 to UEn is shown, but the example 300 may include a single UE, or FIG. 3A to FIG. 3E Different numbers of UEs are shown.

[0093] like Figure 3A As shown, BS 110 and one or more UEs 120 may communicate on narrow beams, which may be beams refined from a wide beam associated with BS 110 (and narrow relative to the wide beam). In some aspects, each UE 120 and BS 110 communicate on a narrow beam pair, which may include a narrow transmit beam and a narrow receive beam. In these cases, BS 110 may transmit downlink communications to UE 120 using the narrow transmit beam, and may receive uplink communications from UE 120 using the narrow receive beam. Similarly, UE 120 may transmit uplink communications to BS 110 using the narrow transmit beam, and may receive downlink communications from BS 110 using the narrow receive beam.

[0094] like Figure 3B As shown by reference numeral 302, a UE 120 (or each UE 120) in one or more UEs 120 may send an indication of one or more beam performance indicators to a BS 110. In some aspects, the UE 120 sends the indication of the one or more beam performance indicators based at least in part on receiving a request for the one or more beam performance indicators from the BS 110. In some aspects, the UE 120 periodically sends the indication of the one or more beam performance indicators at specific time intervals.

[0095] The one or more beam performance indicators may be beam performance indicators associated with one or more narrow beams of BS 110 and / or UE 120 (such as a narrow transmit beam of BS 110, a narrow receive beam of BS 110, a narrow transmit beam of UE 120, a narrow receive beam of UE 120, etc.). For example, one or more beam performance indicators may include one or more channel state information (CSI) reports associated with one or more narrow beams, hybrid automatic repeat request (HARQ) feedback associated with one or more narrow beams (e.g., an acknowledgment (ACK) or a negative ACK (NACK) for downlink communications received from BS 110 on a narrow transmit beam of BS 110 and / or a narrow receive beam of UE 120), an indication of uplink reception quality associated with one or more narrow beams (e.g., one or more RSRP measurements, one or more RSRQ measurements, one or more RSSI measurements, one or more CQI measurements, etc., associated with a narrow transmit beam of BS 110 and / or a narrow receive beam of UE 120), and the like.

[0096] like Figure 3B As further shown in FIG. 1 and reference numeral 304, BS 110 may determine that beam performance of one or more narrow beams associated with one or more UEs 120 does not satisfy a performance threshold. The performance threshold may be a measurement threshold (e.g., an RSRP measurement threshold, an RSRQ measurement threshold, etc.), may be a channel quality threshold (e.g., a CQI threshold), may be another type of threshold, or a combination thereof.

[0097] In some aspects, BS 110 determines that beam performance of one or more narrow beams associated with one or more UEs 120 does not meet a performance threshold based at least in part on an indication of a beam performance indicator received from one or more UEs 120. In some aspects, BS 110 determines that beam performance of one or more narrow beams associated with one or more UEs 120 does not meet a performance threshold based at least in part on statistics and / or trends in the beam performance indicator, such as a trend indicating that beam performance of the one or more narrow beams is degrading or worsening, that beam performance of the one or more narrow beams is degrading or worsening at a particular rate, etc.

[0098] like Figure 3C306, the BS 110 may determine to activate one or more coverage enhancement parameters. In some aspects, the BS 100 may determine to activate the one or more coverage enhancement parameters to mitigate degraded or worsened beam performance of one or more narrow beams associated with the one or more UEs 120, to maintain beam performance of one or more narrow beams associated with the one or more UEs 120, to improve beam performance of one or more narrow beams associated with the one or more UEs 120, etc. In some aspects, the BS 110 determines to activate the one or more coverage enhancement parameters based at least in part on determining that beam performance of one or more narrow beams associated with the one or more UEs 120 does not meet a performance threshold.

[0099] In some aspects, BS 110 may determine to activate one or more coverage enhancement parameters for other purposes related or unrelated to beam performance. For example, BS 110 may determine to activate one or more coverage enhancement parameters for various communication processes, such as random access channel processes or reference signal transmission and / or reporting. As another example, BS 110 may determine to activate one or more coverage enhancement parameters for a particular type of UE, such as a UE with reduced capability or an IoT UE, to address and / or offset reduced bandwidth capability, reduced battery capability, and / or other UE capabilities. As another example, BS 110 may determine to activate one or more coverage enhancement parameters for highly mobile UEs.

[0100] In some aspects, BS 110 identifies one or more coverage enhancement parameters based at least in part on UE 120. For example, BS 110 may identify one or more UE-specific coverage enhancement parameters for UE 120. In some aspects, BS 110 identifies one or more coverage enhancement parameters based at least in part on a group of UEs associated with UE 120. For example, BS 110 may identify one or more group-common coverage enhancement parameters for UE 120 that are associated with a group of UEs associated with UE 120.

[0101] In some aspects, the BS 110 identifies a plurality of one or more sets of coverage enhancement parameters for the UE 120, wherein each of the one or more sets of coverage enhancement parameters is associated with a specific physical channel time or communication process. For example, the BS 110 may identify one or more sets of coverage enhancement parameters for a CSI report. As another example, the BS 110 may identify one or more sets of coverage enhancement parameters for a physical downlink control channel (PDCCH) communication. As another example, the BS 110 may identify one or more sets of coverage enhancement parameters for a physical downlink shared channel (PDSCH) communication. As another example, the BS 110 may identify one or more sets of coverage enhancement parameters for a physical uplink control channel (PUCCH) communication. As another example, the BS 110 may identify one or more sets of coverage enhancement parameters for a physical uplink shared channel (PUSCH) communication. As another example, the BS 110 may identify one or more sets of coverage enhancement parameters for sending and / or receiving semi-persistent scheduling (SPS) communications. As another example, the BS 110 may identify one or more sets of coverage enhancement parameters for sending and / or receiving configured grant communications. In some aspects, BS 110 may identify one or more combinations of one or more coverage enhancement parameter sets described above and / or other one or more coverage enhancement parameter sets.

[0102] In some aspects, the BS 110 may identify a configured coverage enhancement parameter or a combination of configured coverage enhancement parameters for a particular UE 120 (e.g., based at least in part on UE capabilities), a particular group of UEs 120 (e.g., based at least in part on a group type), a particular physical channel type, a particular communication procedure, etc. In some aspects, the configured coverage enhancement parameter or the combination of configured coverage enhancement parameters may be indicated in a table, specification, database, wireless communication standard, etc. In these cases, the BS 110 may identify one or more coverage enhancement parameters from a plurality of candidate coverage enhancement parameters or candidate combinations of coverage enhancement parameters (e.g., for a UE 120, a group of UEs 120, a particular physical channel type, a particular communication procedure type, etc.) identified in the table, specification, database, wireless communication standard, etc.

[0103] Examples of coverage enhancement parameters may include, but are not limited to, repetition parameters, time resource allocation parameters, frequency resource allocation parameters, payload size parameters, and / or other types of parameters. A repetition parameter may indicate the number of repetitions used to send or receive a specific type of communication, such as a reference signal, a report, a PDCCH communication, a PDSCH communication, a PUCCH communication, a PUSCH communication, etc. A time resource allocation parameter may indicate one or more time domain resources (e.g., time slots, symbols, subframes, etc.) used to send or receive a specific type of communication, such as a reference signal, a report, a PDCCH communication, a PDSCH communication, a PUCCH communication, a PUSCH communication, etc.

[0104] The frequency resource allocation parameter may indicate one or more frequency domain resources (e.g., resource blocks, resource elements, subcarriers, component carriers, etc.) used to send or receive a specific type of communication, such as a reference signal, a report, a PDCCH communication, a PDSCH communication, a PUCCH communication, a PUSCH communication, etc. The payload size parameter may indicate a payload size limit for a specific type of communication (such as a reference signal, a report, a PDCCH communication, a PDSCH communication, a PUCCH communication, a PUSCH communication, etc.).

[0105] In some aspects, the BS 110 may send an indication of the one or more coverage enhancement parameters to one or more UEs 120. For example, the BS 110 may send an indication of the one or more coverage enhancement parameters to the one or more UEs 120 prior to indicating activation of the one or more coverage enhancement parameters. In some aspects, the BS 110 sends an indication of the one or more coverage enhancement parameters to the UE 120 in UE-specific signaling, such as UE-specific radio resource control (RRC) signaling, UE-specific DCI signaling, UE-specific MAC-CE signaling, etc. In some aspects, the BS 110 sends an indication of the one or more coverage enhancement parameters to the plurality of UEs 120 in group common signaling, such as group common physical downlink control channel (GC-PDCCH) communication, in a search space configuration for DCI associated with GC-PDCCH communication, etc. In some aspects, the BS 110 sends an indication of a different set of one or more coverage enhancement parameters in a corresponding configuration for each channel type and / or communication process type.

[0106] like Figure 3C10 and further illustrated by reference numeral 308, BS 110 may send an indication to activate one or more coverage enhancement parameters to one or more UEs 120. Specifically, BS 110 may send the indication to activate one or more coverage enhancement parameters in a single dynamic signaling communication. For example, if one or more UEs 120 include a single UE 120, BS 110 may unicast the indication to activate one or more coverage enhancement parameters to UE 120 in a single UE-specific downlink communication. As another example, if one or more UEs 120 include a plurality of UEs 120, BS 110 may broadcast, multicast, or groupcast the indication to activate one or more coverage enhancement parameters to the plurality of UEs 120 in a single group common downlink communication.

[0107] In some aspects, the single dynamic signaling communication comprises a single downlink control information (DCI) communication. In some aspects, the single dynamic signaling communication comprises a single media access control control element (MAC-CE) communication. In some aspects, the single dynamic signaling communication comprises a single GC-PDCCH communication.

[0108] like Figure 3C 3 and further illustrated by reference numeral 310, one or more UEs 120 may activate one or more coverage enhancement parameters. In some aspects, one or more UEs 120 may receive a single dynamic signaling communication and may activate one or more coverage enhancement parameters based at least in part on an indication included in the single dynamic signaling communication to activate the one or more coverage enhancement parameters.

[0109] like Figure 3D 3 and as indicated by reference numeral 312, BS 110 and one or more UEs 120 may communicate based at least in part on one or more coverage enhancement parameters. Specifically, after one or more coverage enhancement parameters have been activated, BS 110 and one or more UEs 120 may communicate based at least in part on one or more coverage enhancement parameters.

[0110] For example, UE 120 may transmit a specific number of repetitions of PUCCH communications, PUSCH communications, channel state information reference signals (CSI-RS), and / or other types of uplink communications to BS 110 using a narrow transmit beam associated with UE 120 based at least in part on a repetition parameter included in the one or more coverage enhancement parameters. As another example, UE 120 may monitor a specific number of repetitions of PDCCH communications, PDSCH communications, CSI-RS, and / or other types of downlink communications from BS 110 using a narrow receive beam associated with UE 120 based at least in part on a repetition parameter included in the one or more coverage enhancement parameters.

[0111] As another example, BS 110 may transmit a specific number of repetitions of PDCCH communications, PDSCH communications, CSI-RS, and / or other types of downlink communications to one or more UEs 120 using a narrow transmit beam associated with BS 110 based at least in part on a repetition parameter included in the one or more coverage enhancement parameters. As another example, BS 110 may monitor a specific number of repetitions of PUCCH communications, PUSCH communications, CSI-RS, and / or other types of uplink communications from one or more UEs 120 using a narrow receive beam associated with BS 110 based at least in part on a repetition parameter included in the one or more coverage enhancement parameters.

[0112] As another example, UE 120 may transmit PUCCH communication, PUSCH communication, CSI-RS, and / or other types of uplink communication to BS 110 using a narrow transmit beam associated with UE 120 in one or more frequency domain resources indicated by frequency resource allocation parameters included in one or more coverage enhancement parameters, in one or more time domain resources indicated by time resource allocation parameters included in one or more coverage enhancement parameters, etc. As another example, UE 120 may monitor repetitions of PDCCH communication, PDSCH communication, CSI-RS, and / or other types of downlink communication from BS 110 using a narrow receive beam associated with UE 120 in one or more frequency domain resources indicated by frequency resource allocation parameters included in one or more coverage enhancement parameters, in one or more time domain resources indicated by time resource allocation parameters included in one or more coverage enhancement parameters, etc.

[0113] As another example, BS 110 may transmit PDCCH communications, PDSCH communications, CSI-RS, and / or other types of downlink communications to one or more UEs 120 using a narrow transmit beam associated with BS 110 in one or more frequency domain resources indicated by frequency resource allocation parameters included in the one or more coverage enhancement parameters, in one or more time domain resources indicated by time resource allocation parameters included in the one or more coverage enhancement parameters, etc. As another example, BS 110 may monitor PUCCH communications, PUSCH communications, CSI-RS, and / or other types of uplink communications from one or more UEs 120 using a narrow receive beam associated with BS 110 in one or more frequency domain resources indicated by frequency resource allocation parameters included in the one or more coverage enhancement parameters, in one or more time domain resources indicated by time resource allocation parameters included in the one or more coverage enhancement parameters, etc.

[0114] As another example, BS 110 may use a narrow transmit beam associated with BS 110 to transmit PDCCH communications, PDSCH communications, SPS communications, configured authorization communications, or another type of scheduled communications to schedule time domain resources and / or frequency domain resources for BS 110 and / or one or more UEs 120 based at least in part on frequency resource allocation parameters included in one or more coverage enhancement parameters and / or time resource allocation parameters included in one or more coverage enhancement parameters.

[0115] As another example, UE 120 may transmit PUCCH communications, PUSCH communications, CSI-RS, and / or other types of uplink communications having a payload size indicated by a payload size parameter included in one or more coverage enhancement parameters to BS 110 using a narrow transmit beam associated with UE 120. As another example, BS 110 may transmit PDCCH communications, PDSCH communications, CSI-RS, and / or other types of downlink communications having a payload size indicated by a payload size parameter included in one or more coverage enhancement parameters to one or more UEs 120 using a narrow transmit beam associated with BS 110.

[0116] like Figure 3E 1 and as shown by reference numeral 314, one or more UEs 120 may deactivate one or more coverage enhancement parameters at a time after activating the one or more coverage enhancement parameters. The one or more coverage enhancement parameters may be valid and used by the BS 110 and the one or more UEs 120 until the one or more coverage enhancement parameters are deactivated.

[0117] In some aspects, the one or more UEs 120 deactivate the one or more coverage enhancement parameters based at least in part on the expiration of a timer associated with the one or more coverage enhancement parameters relative to the time when the one or more coverage enhancement parameters were activated. An indication of the duration of the timer may be signaled by the BS 110 to the one or more UEs 120, or may be configured in a data structure of the one or more UEs 120 (e.g., in a memory device, in a storage device, in a table, in an electronic file or file system, in a database, etc.) such that the one or more UEs 120 may determine the duration of the timer without additional signaling from the BS 110.

[0118] In some aspects, one or more UEs 120 deactivate one or more coverage enhancement parameters based at least in part on explicit or implicit signaling received from BS 110. The signaling may be dynamic signaling included in a DCI communication, a MAC-CE communication, etc. For example, one or more UEs 120 may deactivate (immediately or after a configured duration) one or more coverage enhancement parameters based at least in part on receiving a communication from BS 110 that explicitly indicates that one or more coverage enhancement parameters are to be deactivated. As another example, one or more UEs 120 may deactivate one or more coverage enhancement parameters based at least in part on receiving a communication from BS 110 that explicitly indicates that one or more coverage enhancement parameters are to be deactivated after a specified duration. As another example, one or more UEs 120 may deactivate one or more coverage enhancement parameters based at least in part on receiving a communication (e.g., a beam switching command or another type of communication) from BS 110 that implicitly indicates that one or more UEs 120 are to be deactivated (immediately or after a configured duration).

[0119] In this way, the BS 110 may signal the coverage enhancement parameter to the one or more UEs 120. The BS 110 may signal the activation of the coverage enhancement parameter to the one or more UEs 120 in a single dynamic signaling communication, and the one or more UEs 120 may activate the coverage enhancement parameter and may communicate based at least in part on the coverage enhancement parameter (e.g., on one or more narrow beams). In this way, a single dynamic signaling communication of the coverage enhancement parameter from the BS 110 allows for maintaining or improving beam performance of the one or more narrow beams while indicating the activation to the one or more UEs 120 in a manner that saves signaling overhead (which reduces radio resource consumption).

[0120] As mentioned above, FIG. 3A to FIG. 3E is provided as one or more examples. Other examples may be related to FIG. 3A to FIG. 3E Described differently.

[0121] Figure 4 4 is a diagram illustrating an example process 400 performed, for example, by a UE according to the present disclosure.

For example, as described above, the UE (e.g., using the receive processor 258, the transmit processor 264, the controller / processor 280, the memory 282, etc.) may receive an indication to activate one or more coverage enhancement parameters in a single dynamic signaling communication.

Additionally or alternatively, two or more blocks of the process 400 may be performed in parallel.
