Method and apparatus for power control of independent links

Abstract

Various aspects of the present disclosure relate to power control of independent links. For example, power control at a device may be based on transmissions on multiple links. In some aspects, independent links may involve a first device (e.g., user equipment) communicating with different devices (e.g., transmit reception points (TRPs) or TRP sets) via different independent links. For example, a first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, power control of the first device may be based on power control commands received on multiple links. In some scenarios, power control constraints that take into account transmission power on multiple links may be met.

Technical Field

[0004] Various aspects described herein relate to wireless communications and, in particular, but not exclusively, to power control of independent links. Background Art

[0005] Wireless communication networks are widely deployed to provide various communication services such as telephony, video, data, messaging, broadcasts, etc. Such networks, which are typically multiple-access networks, support communication for multiple users (e.g., when the users are using devices such as user equipment (UE)) by sharing the available network resources.

[0006] A UE may be served by multiple transmit-receive points (TRPs). For example, coordinated multi-point (CoMP) techniques use joint transmission or dynamic point selection to enable a UE to communicate with different TRPs (e.g., gNodeBs or eNodeBs) on different links. Accordingly, there is a need for techniques that enable devices to communicate efficiently via multiple links. Summary of the invention

[0073] In some aspects, the present disclosure relates to communicating via multiple independent links. For example, a user equipment (UE) may communicate with different transmit reception points (TRPs) or TRP sets via different independent links. In some aspects, a transport block carried by a specific one of these independent links is processed independently of a transport block carried by any other independent link. In some aspects, different links may be associated with different beams.

[0074] In some aspects, the present disclosure relates to different operations for multi-link multi-beam communication. In a first implementation, the links are grouped together as a channel sensing group. In a second implementation, control information for different links is sent on one or more links. A third implementation involves dynamically controlling uplink and downlink allocations for different links. In a fourth implementation, power control at the device is based on transmissions on multiple links. In a fifth implementation, channel state feedback is based on channel states of multiple links. A sixth implementation involves sending beam information for a link on at least one other link. In a seventh implementation, event triggering is based on measurements from multiple links.

[0075] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configuration in which the concepts described herein may be practiced. This detailed description includes specific details to provide a thorough understanding of the various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In addition, alternative configurations may be designed without departing from the scope of the present disclosure. In addition, well-known elements will not be described in detail or will be omitted to avoid confusing the relevant details of the present disclosure.

[0076] The various concepts presented throughout this disclosure can be implemented across a wide variety of telecommunication systems, network architectures, and communication standards. For example, the Third Generation Partnership Project (3GPP) is a standards body that defines several wireless communication standards for networks involving Evolved Packet Systems (EPS), often referred to as Long Term Evolution (LTE) networks. Evolved versions of LTE networks, such as fifth generation (5G) networks, can provide many different types of services or applications, including but not limited to web browsing, video streaming, VoIP, mission-critical applications, multi-hop networks, remote operations with real-time feedback (e.g., remote surgery), etc. Thus, the teachings herein can be implemented based on various network technologies, including but not limited to: 5G technology, fourth generation (4G) technology, third generation (3G) technology, and other network architectures. Similarly, various aspects of the present disclosure may be extended to networks based on the 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE), Advanced LTE (LTE-A) (in FDD, TDD, or both modes), Universal Mobile Telecommunications System (UTMS), Global System for Mobile Communications (GSM), Code Division Multiple Access (CDMA), Evolution Data Optimized (EV-DO), Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Ultra Wideband (UWB), Bluetooth, and / or other suitable systems. In addition, the techniques described herein may be used for a downlink, an uplink, a peer-to-peer link, or some other type of link.

[0077] The actual telecommunication standard, network architecture, and / or communication standard adopted will depend on the specific application and the overall design constraints imposed on the system. For the purpose of illustration, various aspects in the context of a 5G system, a millimeter wave (mmW) system, or an LTE system may be described below. However, it should be appreciated that the teachings herein may also be used in other systems. Therefore, references to functionality in the context of 5G, mmW, or LTE terms should be understood to be equally applicable to other types of technologies, networks, components, signaling, and the like.

[0078] Example Communication System

[0079] Figure 1An example of a wireless communication system 100 is illustrated in which user equipment (UE) can communicate with other devices via wireless communication signaling. For example, a first UE 102 and a second UE 104 can communicate with a transmission reception point (TRP) 106 using wireless communication resources managed by a TRP 106 and / or other network components (e.g., a core network 108, an Internet service provider (ISP) 110, a peer device, etc.). In some implementations, one or more components of the system 100 can communicate with each other directly via a device-to-device (D2D) link 112 or some other similar type of direct link.

[0080] Communication of information between two or more components of system 100 may involve multiple independent links. For example, UE 102 may communicate with TRP 106 via a first link and communicate with TRP 114 via a second link. Alternatively or additionally, some other component of system 100 may communicate via two or more independent links. Thus, in accordance with the teachings herein, one or more of UE 102, UE 104, TRP 106, or some other component of system 100 may include module 116 for multi-link signaling.

[0081] The components and links of the wireless communication system 100 may take different forms in different implementations. For example, but not limited to, a UE may be a cellular device, an Internet of Things (IoT) device, a cellular IoT (CIoT) device, an LTE wireless cellular device, a machine type communication (MTC) cellular device, a smart alarm, a remote sensor, a smartphone, a mobile phone, a smart meter, a personal digital assistant (PDA), a personal computer, a mesh node, and a tablet computer.

[0082] In some aspects, a TRP may refer to a physical entity that includes a radio head function for a specific physical cell. In some aspects, a TRP may include 5G New Radio (NR) functionality with an air interface based on orthogonal frequency division multiplexing (OFDM). For example, but not limited to, NR may support enhanced mobile broadband (eMBB), mission-critical services, and large-scale deployment of IoT devices. In one or more aspects, the functionality of a TRP may be similar to (or incorporated into) the functionality of the following: CIoT base station (C-BS), B node, evolved B node (eNodeB), radio access network (RAN) access node, radio network controller (RNC), base station (BS), radio base station (RBS), base station controller (BSC), base transceiver station (BTS), transceiver function (TF), radio transceiver, radio router, basic service set (BSS), extended service set (ESS), macro cell, macro node, home evolved B node (HeNB), femto cell, femto node, micro node, or some other suitable entity. In different scenarios (e.g., NR, LTE, etc.), the TRP may be referred to as a gB node (gNB), eNB, base station, or referenced using other terms.

[0083] Various types of network-to-device links and D2D links may be supported in the wireless communication system 100. For example, the D2D link may include, but is not limited to, a machine-to-machine (M2M) link, an MTC link, a vehicle-to-vehicle (V2V) link, and a vehicle-to-everything (V2X) link. The network-to-device link may include, but is not limited to, an uplink (or reverse link), a downlink (or forward link), and a vehicle-to-network (V2N) link.

[0084] Example Standalone Link

[0085] Figure 2 A communication system 200 is illustrated in which a user equipment (UE) 202 communicates with at least one transmit reception point (TRP) 204 and at least one TRP 206 via independent links 208 and 210, respectively. In different implementations, TRP 204 may be a single TRP or a group of TRPs. Similarly, TRP 206 may be a single TRP or a group of TRPs. The number of independent links may be 2, 3, or more. To reduce the number of independent links, the number of independent links may be 2, 3, or more. Figure 2 In some implementations, UE 202 may correspond to UE 102, UE 104, or Figure 1 In some implementations, TRP 204 or TRP 206 may correspond to TRP 106, TRP 114, or Figure 1 some other component of the .

[0086] Links 208 and 210 are independent in the sense that UE 202 processes the transport blocks (TBs) of each link independently. For example, a first TB process 212 may process the TBs of link 208 independently of a second TB process 214 that processes the TBs of link 210. In some aspects, the independent processing involves error detection of the TBs. For example, the TBs of different links may be covered by their own independent cyclic redundancy check (CRC) values. Therefore, in this case, the CRC process run by the first TB process 212 is independent of the CRC process run by the second TB process 214.

[0087] The TRP may establish multiple independent links for the UE. For example, after establishing a first link with the UE, the TRP may configure at least one other TRP to establish at least one other link with the UE. In some aspects, each link may have its own unique identifier (ID) and use a unique scrambled ID.

[0088] In some aspects, a TRP may refer to a physical entity that contains radio head functionality for a particular physical cell. The functionality may be similar in one or more aspects to (or incorporated into) the functionality of: a NodeB, an evolved NodeB, a g NodeB, a radio network controller (RNC), a base station (BS), a radio base station (RBS), a base station controller (BSC), a base transceiver station (BTS), a transceiver function (TF), a radio transceiver, a radio router, a basic service set (BSS), an extended service set (ESS), a macro cell, a macro node, a home eNB (HeNB), a femto cell, a femto node, a pico node, or some other similar entity. Figure 2 TRPs 204 and 206 may communicate with each other via a network entity 216, a direct communication link 218, or some other link.

[0089] Example Beamforming System

[0090] In some implementations, multiple independent links are used by devices equipped with multiple transmit antennas and multiple receive antennas. One example is a millimeter wave (mmW) system, where multiple antennas are used for beamforming (e.g., in the 30 GHz, 60 GHz, etc. range). For example, a device may communicate with other devices in a time division multiplexing (TDM) or time division duplexing (TDD) manner. That is, a particular device may transmit to (or receive from) a first device in a first time interval, and then transmit to (or receive from) a second device in a second time interval.

[0091] Figure 3A communication system 300 is illustrated in which a mmW UE 302 communicates with a first mmW TRP 304 and a second mmW TRP 306 via different beamforming directions. In some aspects, the mmW UE 302, the first mmW TRP 304, and the second mmW TRP 306 may correspond to Figure 2 UE 202, at least one TRP 204 and at least one TRP 206.

[0092] The mmW UE 302 may communicate via any of a plurality of directional beams, as indicated by beam set 308. The first mmW TRP 304 may communicate via any of a plurality of directional beams, as indicated by beam set 310. The second mmW TRP 306 may communicate via any of a plurality of directional beams, as indicated by beam set 312. For example, the UE 302 may communicate with the first mmW TRP 304 via a first beamforming direction 314 and communicate with the second mmW TRP 306 via a second beamforming direction 316.

[0093] Example Beamforming Device

[0094] Figure 4 The apparatus 400 (eg, a UE) supporting multiple independent links and beams is illustrated in greater detail. In some aspects, the apparatus 400 may correspond to Figure 2 UE 202 or Figure 3 mmW UE 302.

[0095] The device has "N" intermediate frequency (IF) / baseband chains 402. N can be 2 or greater. Each IF chain can be connected to multiple RF chains 404 (M). M can be 1 or greater. Each RF chain can be connected to an antenna element (e.g., subarray) 406. Therefore, each IF / baseband chain 402 (e.g., for a corresponding TB process 408) can be connected to a different subarray at the device. Due to the dynamics of the mmW channel (e.g., blocking), the subarray at the device can be used to improve robustness. That is, antenna diversity can improve communication performance at the device. For example, if one link (or more than one link) is blocked, the device can still communicate via another link or other links.

[0096] In mmW systems, multiple subarrays may be used at the device to cover different beam directions. In some implementations, rank 2 reception at the device (e.g., for MIMO) may be achieved with dual polarization at one subarray (e.g., a patch antenna). In some implementations, rank 2 reception at the device may be achieved with {H,H}, {V,V}, {H,V}, {V,H} polarizations, where H (horizontal) or V (vertical) polarizations are at different subarrays (e.g., dipole antennas).

[0097] Due to physical limitations, dual polarization may be difficult to achieve for some placements of subarrays at a device (eg, a phone). For example, dual polarization may be difficult to achieve for subarrays located at the edge or top of a phone.

[0098] Figure 5 An example of how an antenna subarray may be located in a device 500 (eg, a phone) is illustrated. In some aspects, the device 500 may correspond to Figure 2 UE 202 Figure 3 mmW UE 302, or Figure 4 Device 400.

[0099] Each dipole antenna 502 can be used for H or V polarization. Patch antenna 504 can be used for dual polarization.

[0100] In some aspects, the present disclosure relates to using physical / spatial separation for different subarrays to enable each IF chain to be served by a corresponding TRP. Thus, two or more independent transport blocks (TBs) can be served by two or more different TRPs using two or more IF chains.

[0101] For example, Figure 6 , a first antenna subarray 602 of the device 600 receives a first TB from a first set of TRPs (e.g., one or more TRPs) via a first link 604, and a second antenna subarray 606 receives a second TB from a second set of TRPs (e.g., one or more TRPs) via a second link 608. Additional TBs may be received from other TRPs via other links. For example, a link may be established via a third subarray 610, a patch antenna 612, or some other antenna (not shown). Each of these links may be independent, as discussed above.

[0102] Since the antenna subarrays of the device 600 (e.g., UE) may have different polarizations (e.g., H or V), different TRPs may concurrently serve corresponding TBs of the device 600 via different antenna subarrays. For example, a first TRP may send TB1 to the first antenna subarray 602 while a second TRP sends TB2 to the second antenna subarray 606. In some aspects, the device 600 may correspond to Figure 2 UE 202 Figure 3 mmW UE 302, Figure 4 Device 400, or Figure 5 Device 500.

[0103] Communication via multiple independent links

[0104] In some aspects, the disclosure relates to sharing resources in various multi-link scenarios. In some aspects, each link is independent, as discussed herein (eg, the TBs of each link are processed independently).

[0105] Additionally, as discussed above, a particular link may correspond to a particular beam transmitted and / or received via a particular subarray or a particular set of subarrays.Thus, in some aspects, the present disclosure relates in some aspects to sharing resources in various multi-link multi-beam scenarios.

[0106] According to the teachings herein, the following operations may be supported in conjunction with communications over multiple independent links: channel sensing for multiple links, controlling channel transmission / reception to / from multiple TRPs, HARQ feedback to multiple TRPs, subframe allocation for multiple links, power control for multiple links, uplink sounding for multiple links, downlink CSI reception for multiple links, beam switching procedures for multiple links, beam recovery procedures for multiple links, RACH procedures for multiple links, measurements for multiple links, and event triggering for multiple links. The following are several examples of these operations, summarized as: channel sensing, control information, allocation, power control, channel state feedback, beam information, and event triggering categories.

[0107] Multi-link channel sensing

[0108] In some aspects, the present disclosure relates to a multi-link multi-beam scenario involving grouping links together as a channel sensing group. For example, the same channel sensing parameters may be used for the links in a group. As another example, a decision to transmit via one or more links in a group may be based on channel sensing for one or more links in the group (e.g., where sensing for different links may cover different beam directions).

[0109] An example of this scenario is Figure 7 Shown in. Figure 7A communication system 700 is illustrated in which a UE 702 communicates with a first TRP 704 via a first link 708 and communicates with a second TRP 706 via a second link 710. The UE 702 includes functionality of first channel sensing 712 to obtain information about a channel of the first link 708 and functionality of second channel sensing 714 to obtain information about a channel of the second link 710. The first TRP 704 includes functionality of first channel sensing 716 to obtain information about a channel of the first link 708. The second TRP 706 includes functionality of second channel sensing 718 to obtain information about a channel of the second link 710. In some aspects, the UE 702 may correspond to Figure 2 UE 202 Figure 3 mmW UE302, Figure 4 Device 400, or Figure 5 In some aspects, TRP 704 or TRP 706 may correspond to Figure 2 TRP204, Figure 2 TRP 206 Figure 3 mmW TRP 304, or Figure 3 mmW TRP 306.

[0110] According to the teachings herein, any of the UE 702, the first TRP 704, or the second TRP 706 may support a channel sensing group for the first link 708 and the second link 710. For example, at the UE 702, the first channel sensing 712 and the second channel sensing 714 may collaborate to share sensing information or use the same sensing parameters. As another example, the first channel sensing 716 of the first TRP 704 and the second channel sensing 718 of the second TRP 706 may collaborate (e.g., via the link 720) to share sensing information or use the same sensing parameters.

[0111] These and other aspects of channel sensing in a multi-link scenario are discussed below in the section entitled "Examples of Multi-Link Channel Sensing."

[0112] Multilink Control Information

[0113] In some aspects, the present disclosure relates to a multi-link multi-beam scenario involving sending control information of different links on one or more links. For example, a link may carry control information of multiple links (e.g., a control channel on a link may indicate the presence of at least one other link or traffic on at least one other link; or a link may transmit feedback of multiple links). As another example, each link may be provided (e.g., as a primary link or a secondary link) to carry a specific type of control information of one or more links.

[0114] An example of this scenario is Figure 8 Shown in. Figure 8 A communication system 800 is illustrated in which a UE 802 communicates with a first TRP 804 via a first link 808 and communicates with a second TRP 806 via a second link 810. The UE 802 includes functionality of control information management 812 to send and receive control information via the first link 808 and the second link 810. The first TRP 804 includes functionality of control information management 816 to send and receive control information via the first link 808. The second TRP 806 includes functionality of control information management 818 to send and receive control information via the second link 810. In some aspects, the UE 802 may correspond to Figure 2 UE 202 Figure 3 mmW UE 302, Figure 4 Device 400, or Figure 5 In some aspects, TRP 804 or TRP 806 may correspond to Figure 2 TRP 204 Figure 2 TRP 206 Figure 3 mmW TRP 304, or Figure 3 mmW TRP 306.

[0115] According to the teachings herein, any of UE 802, first TRP 804, or second TRP 806 may support sending control information of one link on another link. For example, control information management 812 of UE 802 may send first link control information 822 on second link 810. As another example, control information management of first TRP 804 may cooperate with control information management of second TRP 806 (e.g., via link 820) to send first link control information 822 on second link 810.

[0116] These and other aspects of communicating control information in a multi-link scenario are discussed below in the sections entitled "Example of Multi-link Control Channel Communication," "Example of Link Indication," and "Example of Multi-link HARQ Feedback."

[0117] Multilink subframe allocation

[0118] In some aspects, the present disclosure relates to a multi-link multi-beam scenario, which involves dynamically controlling the uplink (UL) and downlink (DL) allocations of different links. For example, devices may signal the UL / DL allocations to be used for different links. If the isolation between the links is high, the links may use different TDD / FDD subframe structures. If the isolation is low or for certain types of information (e.g., control information), the transmission direction of a link may be constrained to be the same as the transmission direction of another link (or a subset of the transmission direction of another link) (e.g., the links may use the same TDD / FDD frame structure). In addition, the sounding on different links may be time division multiplexed (TDM).

[0119] An example of this scenario is Fig. 9 Shown in. Fig. 9 A communication system 900 is illustrated in which a UE 902 communicates with a first TRP 904 via a first link 908 and communicates with a second TRP 906 via a second link 910. The UE 902 includes functionality of a link allocation 912 that allocates uplink and downlink resources based on first information 922 about the first link 908 and second information 924 about the second link 910. The first TRP 904 and the second TRP 906 may include similar functionality of link allocations 916 and 918, respectively. In some aspects, the UE 902 may correspond to Figure 2 UE 202 Figure 3 mmW UE302, Figure 4 Device 400, or Figure 5 In some aspects, TRP 904 or TRP 906 may correspond to Figure 2 TRP204, Figure 2 TRP 206 Figure 3 mmW TRP 304, or Figure 3 mmW TRP 306.

[0120] According to the teachings herein, any of the UE 902, the first TRP 904, or the second TRP 906 may allocate uplink and downlink resources based on the first information 922 and the second information 924. For example, if the first information 922 and the second information 924 indicate that the isolation between the first link 908 and the second link 910 is high, the link allocation 912 of the UE 902 may allocate different TDD / FDD subframe structures for the first link 908 and the second link 910. The link allocation 916 of the first TRP 904 and the link allocation 918 of the second TRP 906 may also cooperate (e.g., by sharing the first information 922 or the second information 924 via the link 920) to allocate subframe structures for the first link 908 and the second link 910.

[0121] These and other aspects of allocating resources in a multi-link scenario are discussed below in the sections entitled "Example of Multi-link Subframe Allocation" and "Example of Multi-link Sounding".

[0122] Multi-link power control

[0123] In some aspects, the present disclosure relates to multi-link multi-beam scenarios where power control at a device is based on transmissions on multiple links. For example, power control of a UE may be based on power control commands received on multiple links. As another example, a power control constraint that takes into account transmission power on multiple links may be satisfied.

[0124] An example of this scenario is Fig.10 Shown in. Fig.10 A communication system 1000 is illustrated in which a UE 1002 communicates with a first TRP 1004 via a first link 1008 and communicates with a second TRP 1006 via a second link 1010. The UE 1002 includes functionality of a power control 1012 that controls transmit power based on first information 1022 about the first link 1008 and second information 1024 about the second link 1010. The first TRP 1004 and the second TRP 1006 may include similar functionality of power controls 1016 and 1018, respectively. In some aspects, the UE 1002 may correspond to Figure 2 UE 202 Figure 3 mmWUE 302, Figure 4 Device 400, or Figure 5 In some aspects, TRP 1004 or TRP 1006 may correspond to Figure 2 TRP 204 Figure 2 TRP 206 Figure 3 mmW TRP 304, or Figure 3 mmW TRP 306.

[0125] According to the teachings herein, any of the UE 1002, the first TRP 1004, or the second TRP 1006 may control transmit power based on the first information 1022 and the second information 1024. For example, the power control 1012 of the UE 1002 may set the power control constraints of the first link 1008 and / or the second link 1010 based on the first information 1022 (e.g., the power control command on the first link 1008) and the second information 1024 (e.g., the power control command on the second link 1010). The power control 1016 of the first TRP 1004 and the power control 1018 of the second TRP 1006 may also cooperate (e.g., by sharing the first information 1022 or the second information 1024 via the link 1020) to control the transmit power on the first link 1008 and / or the second link 1010.

[0126] These and other aspects of allocating resources in a multi-link scenario are discussed below in the section entitled "Example of Multi-Link Power Control".

[0127] Multi-link channel status feedback

[0128] In some aspects, the present disclosure relates to multi-link multi-beam scenarios where channel state feedback is based on the channel states of multiple links. For example, channel state information (CSI) feedback may take into account CSI-RS from multiple links (e.g., if antenna subarrays used for the links are close to each other and / or depend on channel conditions).

[0129] An example of this scenario is Fig.11 Shown in. Fig.11 A communication system 1100 is illustrated in which a UE 1102 communicates with a first TRP 1104 via a first link 1108 and communicates with a second TRP 1106 via a second link 1110. The UE 1102 includes functionality of a channel state feedback (CSFB) control 1112 that provides feedback based on first information 1122 about the first link 1108 and second information 1124 about the second link 1110. The first TRP 1104 and the second TRP 1106 may include similar functionality of the CSFB controls 1116 and 1118, respectively. In some aspects, the UE 1102 may correspond to Figure 2 UE202, Figure 3 mmW UE 302, Figure 4 Device 400, or Figure 5 In some aspects, TRP 1104 or TRP 1106 may correspond to Figure 2 TRP 204 Figure 2 TRP 206 Figure 3 mmW TRP 304, or Figure 3 mmW TRP 306.

[0130] According to the teachings herein, any of the UE 1102, the first TRP 1104, or the second TRP 1106 may provide feedback based on the first information 1122 and the second information 1124. For example, if the antenna subarrays for the first link 1108 and the second link 1110 are close to each other, the CSFB control 1112 of the UE 1102 may generate CSI feedback based on the first information 1122 (e.g., CSI-RS from the first link 1108) and the second information 1124 (e.g., CSI-RS from the second link 1110). The CSFB control 1116 of the first TRP 1104 and the CSFB control 1118 of the second TRP 1106 may also cooperate (e.g., by sharing the first information 1122 or the second information 1124 via the link 1120) to provide multi-link based feedback.

[0131] These and other aspects of allocating resources in a multi-link scenario are discussed below in the section entitled "Example of Multi-Link Channel State Feedback".

[0132] Multi-link beam information

[0133] In some aspects, the present disclosure relates to a multi-link multi-beam scenario involving sending beam information of one link on at least one other link. For example, one link may indicate beam switching, link recovery, or link failure of at least one other link.

[0134] An example of this scenario is Fig.12 Shown in. Fig.12 A communication system 1200 is illustrated in which a UE 1202 communicates with a first TRP 1204 via a first link 1208 and communicates with a second TRP 1206 via a second link 1210. The UE 1202 includes functionality of beam control 1212 to send and receive beam information via the first link 1208 and the second link 1210. The first TRP 1204 includes functionality of beam control 1216 to send and receive beam information via the first link 1208. The second TRP 1206 includes functionality of beam control 1218 to send and receive beam information via the second link 1210. In some aspects, the UE 1202 may correspond to Figure 2 UE 202 Figure 3 mmW UE 302, Figure 4 Device 400, or Figure 5In some aspects, TRP 1204 or TRP 1206 may correspond to Figure 2 TRP 204 Figure 2 TRP 206 Figure 3 mmWTRP 304, or Figure 3 mmW TRP 306.

[0135] According to the teachings herein, any of UE 1202, first TRP 1204, or second TRP 1206 may support sending beam information of one link on another link. For example, beam control 1212 of UE 1202 may send first link beam information 1222 on second link 1210. As another example, beam control of first TRP 1204 may cooperate with beam control of second TRP 1206 (e.g., via link 1220) to send first link beam information 1222 on second link 1210.

[0136] These and other aspects of allocating resources in a multi-link scenario are discussed below in the sections entitled "Example of Multi-Link Beam Switching," "Example of Multi-Link Beam Restoration," and "Example of Multi-Link RACH Procedure."

[0137] Multi-link event triggering

[0138] In some aspects, the present disclosure relates to multi-link multi-beam scenarios where event triggering is based on measurements from multiple links. For example, event triggering can be based on aggregated measurements from multiple links.

[0139] An example of this scenario is Fig.13 Shown in. Fig.13A communication system 1300 is illustrated in which a UE 1302 communicates with a first TRP 1304 via a first link 1308 and communicates with a second TRP 1306 via a second link 1310. The UE 1302 includes functionality of an event control 1312 that provides feedback based on first information 1322 about the first link 1308 and second information 1324 about the second link 1310. The first TRP 1304 and the second TRP 1306 may include similar functionality of event controls 1316 and 1318, respectively. According to the teachings herein, any of the UE 1302, the first TRP 1304, or the second TRP 1306 may provide event triggering based on the first information 1322 and the second information 1324. For example, event control 1312 of UE 1302 may generate an event trigger based on first information 1322 (e.g., measurements from first link 1308) and second information 1324 (e.g., measurements from second link 1310). Event control 1316 of first TRP 1304 and event control 1318 of second TRP 1306 may also collaborate (e.g., by sharing first information 1322 or second information 1324 via link 1320) to provide multi-link based event triggering.

[0140] These and other aspects of allocating resources in a multi-link scenario are discussed below in the section entitled "Example of Multi-Link Measurements and Event Triggers".

[0141] Example of multi-link channel sensing

[0142] In some aspects, the present disclosure relates to multi-link channel sensing. In some implementations, a device may use a listen-before-talk (LBT) scheme for shared access with N links (e.g., shared spectrum among TRPs), where N>=2. In some aspects, a TRP or a UE may use LBT-based channel sensing to determine whether the TRP or UE is allowed to transmit on a channel.

[0143] For example, before transmitting, the device may sense energy on the channel or monitor control signals on the channel (e.g., from a TRP or UE). Alternatively or additionally, the device may obtain information from another device indicating the result of energy sensing or message decoding on the channel performed by the other device. For convenience, energy sensing and / or control signal monitoring may be referred to herein as sensing. In addition, sensing may refer to other types of sensing in addition to energy sensing and control signal monitoring. Information obtained as a result of such sensing (e.g., energy sensing, control signal monitoring, etc.) may be referred to herein as sensing information.

[0144] In some aspects, sensing may be associated with a particular link. For example, in some cases, sensing may be performed using the same beam as used for communication via the particular link (e.g., by using the same antenna subarray(s) and antenna settings). Thus, in some aspects, a device may perform a sensing operation for a first link, another sensing operation for a second link, and so on. In some aspects, a sensing operation for a particular link may be referred to herein as sensing a channel of the link (or a channel associated with the link).

[0145] Thus, a device may decide whether to transmit on one or more links based on the results of energy sensing, message decoding (e.g., based on message content), or some other form of sensing. For example, a device may transmit on a particular link if sensing indicates that the transmission is unlikely to interfere with reception at a nearby device (e.g., a device that is communicating with some other device). Alternatively or additionally, a device may decide how to transmit on one or more links based on sensing. For example, a device may adjust its beam (or some other transmission parameter) for a particular link if sensing indicates that the transmission is likely to interfere with reception at a nearby device without adjustment.

[0146] In view of the above, for a multi-link scenario, a device may obtain sensing information of one link or more than one link (e.g., before transmitting on any link). For example, a device communicating via a first link and a second link may determine whether to transmit on the first link based on sensing of the first link and determine whether to transmit on the second link based on sensing of the second link. As another example, a device may determine whether to transmit on the first link based on sensing of the first link and the second link. As yet another example, a device may determine whether to transmit on the first link and the second link based on sensing of the first link. As a further example, a device may determine whether to transmit on the first link and the second link based on sensing of the first link and the second link. Similar sensing schemes may be used for configurations with more than two links.

[0147] In one example scenario, for each link, channel sensing may be performed independently with respect to other links. For example, for each link, the thresholds, parameters, procedures, or any combination thereof used for sensing may be independent. As a specific example, channel sensing on a first link may be based on a first set of parameters and a first procedure, while channel sensing on a second link may be based on a second set of parameters and a second procedure.

[0148] In another example scenario, two or more links may be grouped together as a channel sensing group. Therefore, in some aspects, LBT may be performed on a link as a group. For example, a device may monitor a control signal on one or more links in the group and decide whether to transmit on one or more links in the group based on the sensing result. In some implementations, a device may sense a link in the group and decide whether to transmit on two or more links (e.g., all links or a subset of links) in the group based on the sensing result. In some implementations, a device may sense on multiple links, combine the sensing results, and decide whether to transmit on two or more links in the group based on the combined sensing results. In some implementations, the same channel sensing parameters may be used for links in a group.

[0149] In some scenarios, warp group channel sensing can provide improved sensing. For example, a given subarray (e.g., a dipole antenna) may not have omnidirectional (360 degree) coverage. Therefore, sensing via a given subarray may only provide a portion of the situation of the surrounding environment. In this case, the device may not detect any signal on the link corresponding to the first direction from the device and therefore choose to transmit. However, the transmission performed by the device may still interfere with the receiver located in the second direction from the device. Therefore, when deciding whether to transmit on any or all links in a group, it is advantageous to take into account the sensing on each link in the multiple links (e.g., which can provide wider coverage together). As a result, sensing on multiple links can prove better LBT results.

[0150] In view of the above, in some aspects, the present disclosure relates to multi-link multi-beam channel sensing for a device that communicates via all links in a set of links. For example, a UE may communicate via multiple links, each of which is associated with a corresponding beam. The UE may communicate with a first TRP via a first link (first beam), communicate with at least one other TRP via at least one second link (at least one second beam), and so on. In this case, the UE may perform channel sensing on each of these links independently or as a group, as discussed above.

[0151] In addition, in some aspects, the present disclosure relates to multi-link multi-beam channel sensing for devices that communicate only on a subset of links in a set of links. For example, a TRP may communicate with a UE via a first link (first beam), and the UE may communicate with at least one other TRP via at least one other link (at least one second beam). In this case, the TRP communicates via a subset of links. In some scenarios, a device (e.g., a TRP) may perform channel sensing on a subset of links independently of channel sensing on other links. In other scenarios, a device may collaborate with at least one other device (e.g., a UE, another TRP, etc.) to perform channel sensing as a group (as discussed above). To this end, a device may communicate with another device via another link (e.g., a TRP to TRP channel).

[0152] In some aspects, the present disclosure relates to signaling support for multi-link channel sensing. Here, a device may communicate with another device (or other device) to determine how channel sensing will be performed. For example, the device may indicate which links are grouped together, how to perform group sensing (e.g., sensing on all links or a subset of links, etc.), etc. This signaling can be, for example, from a TRP to a UE, from a UE to a TRP, from a TRP to another TRP, from a UE to another UE, or between other types of devices.

[0153] Example of Multilink Control Channel Communication

[0154] One or more control channels may be defined from multiple TRPs to a UE. The control channel may be a physical downlink control channel (PDCCH) or some other suitable channel. In some aspects, the control channel indicates how data may be sent and / or decoded on a downlink channel (e.g., a physical downlink shared channel, PDSCH) or an uplink channel.

[0155] In one aspect, the present disclosure relates to supporting multiple links, each of which has its own independent control channel. Therefore, in this case, a device (e.g., UE) communicating via multiple links sends and receives control information about one link independently of the control information of any other link.

[0156] In another aspect, the present disclosure relates to supporting multiple links, wherein control information for a link can be communicated via a control channel on at least one other link. In some aspects, a link (e.g., a control channel on a link) can transmit control information for multiple (N) links. For example, a group of links can specify a subset of links (one or more links) for sending control information. Thus, a link (or multiple links) can be used as a control channel for at least one other link.

[0157] In some aspects, these links may be dynamically allocated for sending control information. Some systems use a primary link and a secondary link, where different links may carry different information or carry information in different ways. For example, the primary link may send control information more frequently, or may send more important control information (e.g., ACK / NACK, or mission-critical signaling). Therefore, in the event that the primary link is blocked (or damaged in some other way), the device may dynamically reallocate control information to send on the secondary link.

[0158] As another example of dynamic allocation, different links may have similar reliability and / or channel quality (e.g., the links may be carried on the same carrier frequency). Therefore, different links may be equally suitable for carrying control information. Therefore, the device may dynamically select one or more links that will carry the control information. For example, if a first link that is carrying the control information becomes blocked or is adversely affected in some other way, control may temporarily switch to a second link. Therefore, the device may designate different links to carry control information at different times.

[0159] As yet another example of dynamic allocation, a device may designate one link for some control information and another link for other control information.The information carried by each link may change dynamically over time.

[0160] In view of the above, in some aspects, the present disclosure relates to multi-link multi-beam control information signaling for a device that communicates via all links in a group of links. For example, a UE may communicate via multiple links, each of which is associated with a corresponding beam. The UE may communicate with a first TRP via a first link (first beam), communicate with at least one other TRP via at least one second link (at least one second beam), and so on. In this case, the UE may communicate control information on each of these links independently, or the UE may communicate control information on one or more links in the links as a group, as discussed above.

[0161] In addition, in some aspects, the present disclosure relates to multi-link multi-beam channel sensing for devices that communicate only on a subset of links in a group of links. For example, a TRP may communicate with a UE via a first link (first beam), and the UE may communicate with at least one other TRP via at least one other link (at least one second beam). In this case, the TRP communicates via a subset of links. In some scenarios, a device (e.g., a TRP) may communicate control information on a subset of links independently of control information communications on other links. In other scenarios, a device may collaborate with at least one other device (e.g., a UE, another TRP, etc.) to communicate control information on one or more links in a group of links (as discussed above). To this end, a device may communicate with another device via another link (e.g., a TRP to TRP channel) to obtain control information for another link from the other device or send control information for a link to the other device.

[0162] In some aspects, the present disclosure relates to signaling support for multi-link control channels. Here, a device may communicate with another device (or other device) to determine how control information will be sent. For example, a device may indicate which links will carry what type of control information, when a particular link will carry control information, etc. This signaling can be, for example, from a TRP to a UE, from a UE to a TRP, from a TRP to another TRP, from a UE to another UE, or between other types of devices.

[0163] Example of link indication

[0164] In some cases, the control information may take the form of a link indication. The link indication may indicate the presence of another link or other links (eg, other active links).

[0165] In some aspects, the present disclosure relates to using link indications on at least one control channel between multiple TRPs and a UE. To improve robustness, a control channel on a first link may carry a link indication to indicate the presence of another link or other links. This can ensure better reliability during reception. For example, by knowing that another TRP is transmitting to the UE, the UE will know to check whether it has missed a transmission from the TRP. If the UE does miss a transmission, the UE can take appropriate action (e.g., initiate a retransmission).

[0166] The link indication may be sent in various ways. In some aspects, the link indication may be included in the payload of one link to indicate the presence of at least one other link. In some aspects, the link indication may indicate that control information is (or will be) arriving on at least one other link (e.g., in the current subframe or some other subframe). This signaling may be, for example, from a TRP to a UE, from a UE to a TRP, from a TRP to another TRP, from a UE to another UE, or between other types of devices.

[0167] In view of the above, in some aspects, the present disclosure relates to multi-link multi-beam channel sensing for a device that communicates via all links in a set of links. For example, a UE may communicate via multiple links, each of which is associated with a corresponding beam. The UE may communicate with a first TRP via a first link (first beam), communicate with at least one other TRP via at least one second link (at least one second beam), and so on. In this case, the UE may send or receive a link indication about one link on another link.

[0168] In addition, in some aspects, the present disclosure relates to multi-link multi-beam channel sensing for devices that communicate only on a subset of links in a set of links. For example, a TRP may communicate with a UE via a first link (first beam), and the UE may communicate with at least one other TRP via at least one other link (at least one second beam). In this case, the TRP communicates via a subset of links. In some scenarios, a device (e.g., a TRP) may send or receive a link indication about a link on another link. To this end, the TRPs may share link information with each other. For example, a first TRP may indicate the presence of a link (e.g., a link active at the first TRP) to a second TRP via a backhaul, a TRP to TRP link, or some other type of link.

[0169] Example of multi-link HARQ feedback

[0170] In some cases, the control information may take the form of hybrid automatic repeat request (HARQ) feedback or some other type of feedback (e.g., uplink control signaling). For purposes of illustration, the following discussion will describe a HARQ scenario. However, it should be appreciated that these concepts may be applicable to other types of feedback.

[0171] In one aspect, the present disclosure relates to supporting multiple links, each of which has its own independent HARQ feedback. Thus, in this scenario, a device (e.g., UE) communicating via multiple links processes (e.g., sends and receives) HARQ feedback for one link independently of HARQ feedback for any other link.

[0172] In another aspect, the present disclosure relates to supporting HARQ processes across multiple links. In some aspects, a link (or a subset of links) may process (e.g., send or receive) HARQ feedback for multiple (N) links. For example, a group of links may specify a subset of links (one or more links) for sending HARQ feedback. Thus, a link (or more links) may be used as a HARQ channel for at least one other link. In addition, the HARQ feedback may be responsive to information received on one or more links.

[0173] In some aspects, these links may be dynamically allocated for sending feedback. Some systems use a primary link and a secondary link, where different links may carry different feedback or carry feedback in different ways. For example, the primary link may send feedback more frequently or may send more important feedback (e.g., ACK / NACK). Thus, in the event that the primary link is blocked (or damaged in some other way), the device may dynamically reallocate feedback to send on the secondary link.

[0174] As another example, different links may have similar reliability and / or channel quality (e.g., the links may be carried on the same carrier frequency). Therefore, different links may be equally suitable for carrying feedback. Therefore, the device may dynamically select one or more links that will carry feedback. For example, if a first link that is carrying feedback becomes blocked, the feedback may be temporarily switched to a second link. Therefore, the device may designate different links to carry feedback at different times. As another example, the device may designate one link for some feedback and another link for other feedback.

[0175] In view of the above, in some aspects, the present disclosure relates to multi-link multi-beam feedback for a device that communicates via all links in a group of links. For example, a UE may communicate via multiple links, each of which is associated with a corresponding beam. The UE may communicate with a first TRP via a first link (first beam), communicate with at least one other TRP via at least one second link (at least one second beam), and so on. In this case, the UE may send feedback on each of these links independently, or the UE may send feedback on one or more links in the group of links, as discussed above. In the latter case, the UE may generate feedback based on information received on one or more links in the group.

[0176] In addition, in some aspects, the present disclosure relates to multi-link multi-beam channel sensing for devices that communicate only on a subset of links in a group of links. For example, a TRP may communicate with a UE via a first link (first beam), and the UE may communicate with at least one other TRP via at least one other link (at least one second beam). In this case, the TRP communicates via a subset of links. In some scenarios, a device (e.g., a TRP) may process feedback on a subset of links independently of feedback on other links. In other scenarios, a device may collaborate with at least one other device (e.g., a UE, another TRP, etc.) to manage feedback on one or more links in a group of links (as discussed above). To this end, a device may communicate with another device via another link (e.g., a TRP to TRP channel) to obtain HARQ feedback for another link from the other device or send HARQ feedback for a link to the other device.

[0177] In some aspects, the present disclosure relates to signaling support for multi-link feedback. Here, a device may communicate with another device (or other device) to determine how feedback will be sent. For example, a device may indicate which links will carry what type of feedback, when a particular link will carry feedback, etc. As discussed above, this signaling can be, for example, from a TRP to a UE, from a UE to a TRP, from a TRP to another TRP, from a UE to another UE, or between other types of devices.

[0178] Example of multilink subframe allocation

[0179] In some aspects, the disclosure relates to subframe allocation in a multi-link scenario.Different subframe structures may be used in different situations.

[0180] According to some aspects of the present disclosure, if the current communication is not full-duplex communication, it is expected that the time division duplex (TDD) structure used for each subframe is compatible on all N links. By using a compatible TDD structure on different links, receiver saturation can be avoided. In this case, the transmission direction of a link (e.g., uplink or downlink) is specified to be the same as the direction of other N-1 links or a subset of the direction of other N-1 links. For example, if a link is in the downlink direction during a specific symbol, another link should also be in the downlink direction during the symbol. For example, this type of configuration can be used for the communication of more important information (e.g., control information, high QoS data, etc.).

[0181] According to other aspects of the present disclosure, more flexible allocation of uplinks and downlinks for each link may be allowed. For example, uplink / downlink coordination may not be required between links. In this case, each link may selectively use a different time division duplex (TDD) / FDD subframe structure. For example, if one link is a downlink during a particular symbol, the other link may be an uplink during the symbol. For example, if the RF isolation between the subarrays is high enough (e.g., >30dB), this approach may be used because receiver saturation is unlikely in these cases. Therefore, in a flexible uplink and downlink implementation, some interference between the links may be acceptable. Therefore, in a situation where the RF isolation between the links is relatively high (e.g., because the corresponding antenna subarrays point in different directions), full-duplex operation may be possible. For example, full-duplex operation may also be used for communications of less important information (e.g., best effort data, etc.) with lower reliability requirements.

[0182] According to other aspects of the present disclosure, a mix of full-duplex and non-full-duplex operations may be used. Here, some portions of one or more subframes may share the same direction of different links. For example, all links may share the same downlink portion for downlink control signaling purposes and / or all links may share the same uplink portion for uplink control signaling purposes.

[0183] In addition, one link may provide protected portions of other links by reducing transmit power or blanking transmissions, or one link may provide protected portions of other links by reducing transmit power for a subset of frequency resources or blanking transmissions on a subset of frequency resources. For example, in the case of a 100 MHz bandwidth, one link may reduce transmit power or blank transmissions for the middle portion of the system bandwidth (e.g., 20 MHz in 100 MHz). The frequency resources may not be contiguous in the frequency domain, for example, 20 MHz may be distributed over 100 MHz instead of being contiguous in the frequency domain.

[0184] The links may coordinate protected resources, and the UE or TRP may account for such coordinated resources for receiver processing, e.g., to reduce receiver complexity by knowing the coordination information.

[0185] In some aspects, the present disclosure relates to signaling a subframe or UL / DL configuration to be used on one or more links. For example, a device may communicate with another device (or other devices) to determine the type of subframe or UL / DL configuration to be used on a particular link (or links) and the time when the subframe or UL / DL configuration will be used on the link (or links). This signaling can be, for example, from a TRP to a UE, from a UE to a TRP, from a TRP to another TRP, from a UE to another UE, or between other types of devices.

[0186] In view of the above, in some aspects, the present disclosure relates to multi-link multi-beam channel sensing for a device that communicates via all links in a set of links. For example, a UE may communicate via multiple links, each of which is associated with a corresponding beam. The UE may communicate with a first TRP via a first link (first beam), communicate with at least one other TRP via at least one second link (at least one second beam), and so on. In this case, the UE may use or forward information about each link to enable a scheduler (e.g., at the UE or elsewhere) to determine appropriate subframe allocations.

[0187] In addition, in some aspects, the present disclosure relates to multi-link multi-beam channel sensing for devices that communicate only on a subset of links in a set of links. For example, a TRP may communicate with a UE via a first link (first beam), and the UE may communicate with at least one other TRP via at least one other link (at least one second beam). In this case, the TRP communicates via a subset of links. In some scenarios, a device (e.g., a TRP) may send or receive link information about a link on another link. To this end, the TRPs may share link information with each other. For example, a first TRP may send information about a link (e.g., a link active at a first TRP) to a second TRP via a backhaul, a TRP to TRP link, or some other type of link. In this way, a scheduler (e.g., at a TRP or elsewhere) may determine appropriate subframe allocations.

[0188] Example of multi-link probing

[0189] In some cases, resource (eg, subframe) allocation in a multi-link scenario may be based on dynamic sounding. The sounding may be an uplink sounding, a downlink sounding, or a sounding on some other type of link.

[0190] Uplink sounding may, for example, be used to enable the TRP to configure its downlink beamforming (e.g., based on uplink sounding information received from the UE). For example, the UE may send a sounding reference signal (SRS) to the TRP. In a time division duplex (TDD) environment, reciprocity may be used to estimate the channel in one direction (e.g., DL) based on the channel estimate in another direction (e.g., UL).

[0191] Downlink sounding may, for example, be used to enable the UE to configure its uplink beamforming (e.g., based on downlink sounding information received from the TRP). For example, the TRP may send an SRS to the UE. Here, reciprocity may be used to estimate the channel in the UL based on the channel estimation of the DL.

[0192] In one aspect, the present disclosure relates to supporting multiple links, each of which has its own independent sounding. Thus, in this scenario, a device (e.g., a UE) that is communicating via multiple links performs a sounding operation for one link independently of a sounding operation for any other link. For example, the UE may send a corresponding SRS for each link.

[0193] In another aspect, the present disclosure is directed to supporting sounding across multiple links. Here, the sounding can be time division multiplexed (TDM) within one subframe (e.g., depending on the beamforming direction across the links). For example, if there is high interference between beams (e.g., due to the direction of the beams), the uplink sounding can be sent in a sequential manner (e.g., sending SRS on one link, followed by SRS on another link, etc.).

[0194] In view of the above, in some aspects, the present disclosure relates to multi-link multi-beam sounding for devices that communicate via all links in a group of links. For example, a UE may communicate via multiple links, each of which is associated with a corresponding beam. The UE may communicate with a first TRP via a first link (first beam), communicate with at least one other TRP via at least one second link (at least one second beam), and so on. In this case, the UE may perform sounding operations on each of these links independently, or the UE may perform sounding operations as a group, as discussed above (e.g., successively sending or receiving sounding signals on different links in the group).

[0195] In addition, in some aspects, the present disclosure relates to multi-link multi-beam channel sounding for devices that communicate only on a subset of links in a group of links. For example, a TRP may communicate with a UE via a first link (first beam), and the UE may communicate with at least one other TRP via at least one other link (at least one second beam). In this case, the TRP communicates via a subset of links. In some scenarios, a device (e.g., a TRP) may perform sounding operations on a subset of links independently of sounding operations on other links. In other scenarios, a device may collaborate with at least one other device (e.g., a UE, another TRP, etc.) to perform sounding operations on one or more links in a group of links (as discussed above). To this end, the device may communicate with another device via another link (e.g., a TRP to TRP channel) to obtain sounding information of another link from the other device or send sounding information of a link to the other device.

[0196] In some aspects, the present disclosure relates to signaling support for multi-link sounding. Here, a device may communicate with another device (or other devices) to determine how the sounding will be performed. For example, the device may indicate which links are grouped together for sounding, how to sound each link or a group of links (e.g., concurrently, sequentially, etc.), the direction of the sounding (e.g., uplink or downlink), etc. This signaling can be, for example, from a TRP to a UE, from a UE to a TRP, from a TRP to another TRP, from a UE to another UE, or between other types of devices.

[0197] In some implementations, the TRP may schedule uplink sounding. When scheduling SRS transmissions, the TRP may provide signaling to indicate the transmission direction of each sounding signal.

[0198] Example of Multi-Link Power Control

[0199] In some aspects, the present disclosure relates to multi-link power control.Power control can be implemented using different schemes.

[0200] In one aspect, the present disclosure relates to supporting multiple links, each of which has its own independent power control. Thus, in this scenario, a device (e.g., a UE) that is communicating via multiple links performs power control for one link independently of power control operations for any other link. For example, a TRP may send power control information to a UE via a particular link (e.g., via a control channel) to control the transmit power of the link. The UE may therefore control the power on the link based on a power control command received on the particular link.

[0201] In another aspect, the present disclosure is directed to supporting power control across multiple links (e.g., joint power control). For example, a single power control command may control power on a group of links (e.g., sharing the same spectrum). As another example, power control of a UE may be based on power control commands received on multiple links. As yet another example, a power control constraint that takes into account transmit power on multiple links may be satisfied.

[0202] In either case, an overall power constraint may be used (eg, similar to carrier aggregation). For example, a TRP may specify an overall maximum power limit across multiple links, regardless of whether the links are independent or grouped.

[0203] In view of the above, in some aspects, the present disclosure relates to multi-link multi-beam power control for a device that communicates via all links in a set of links. For example, a UE may communicate via multiple links, each of which is associated with a corresponding beam. The UE may communicate with a first TRP via a first link (first beam), communicate with at least one other TRP via at least one second link (at least one second beam), and so on. In this case, the UE may perform power control operations on each of these links independently, or the UE may perform power control operations as a group, as discussed above. For example, the UE may control power on one or more links based on power control commands received on one or more links.

[0204] In addition, in some aspects, the present disclosure relates to multi-link multi-beam channel power control for devices that communicate only on a subset of links in a group of links. For example, a TRP may communicate with a UE via a first link (first beam), and the UE may communicate with at least one other TRP via at least one other link (at least one second beam). In this case, the TRP communicates via a subset of links. In some scenarios, a device (e.g., a TRP) may perform power control operations on a subset of links independently of power control operations on other links. In other scenarios, a device may collaborate with at least one other device (e.g., a UE, another TRP, etc.) to perform power control operations on one or more links in a group of links (as discussed above). To this end, the device may communicate with another device via another link (e.g., a TRP to TRP channel) to obtain power control information (e.g., a power control command) of another link from the other device or send power control information of a link to the other device.

[0205] In some aspects, the present disclosure relates to signaling support for multi-link power control. Here, a device may communicate with another device (or other device) to determine how power control will be performed. For example, a device may indicate which links are grouped together for power control, how to perform power control for each link or a group of links (e.g., using power control commands on all links or a subset of links, etc.), etc. This signaling can be, for example, from a TRP to a UE, from a UE to a TRP, from a TRP to another TRP, from a UE to another UE, or between other types of devices.

[0206] Example of multi-link channel state feedback

[0207] Channel state feedback (e.g., precoding matrix indicator PMI) from UE in multi-link scenarios can be implemented using different schemes. For channel state information (CSI) feedback, the TRP transmits a CSI reference signal (CSI-RS) detected by the UE. The UE generates CSI feedback (e.g., CQI, PMI, etc.) based on the CSI-RS and sends the CSI feedback to the TRP.

[0208] In one aspect, the present disclosure relates to supporting multiple links, each of which has its own independent channel state feedback. Thus, in this case, a device (e.g., a UE) that is communicating via multiple links performs feedback operations for one link independently of feedback operations for any other link. For example, each link may have its own channel state information (CSI) feedback based on a CSI reference signal (CSI-RS) sent by a TRP on that link.

[0209] In another aspect, the present disclosure relates to supporting channel state feedback across multiple links. For example, CSI feedback for a given link may be based on CSI-RS from multiple links. Thus, the UE may send a joint CSI report. This joint report may be sent on one or more links. When transmitting feedback, the transmitter may provide information about how it uses CSI-RS from multiple links.

[0210] The use of feedback across a group of links can be dynamically invoked based on one or more triggering conditions. For example, joint power control can be invoked when the antenna subarrays being used are relatively close to each other (e.g., separated by less than a threshold distance). As another example, joint power control can be invoked depending on channel conditions.

[0211] The CSI calculated for different links may be different (e.g., due to different coverage directions of the antenna subarrays and / or due to different locations of the antenna subarrays on the device). As an example, the environment seen by different antenna subarrays may be different (e.g., due to different channel conditions in different directions). Therefore, different CSI may be generated for different links (e.g., one of the links may be worse than the other links). In such a case, the device may choose to send a joint CSI report, so the device can use these links jointly for subsequent communications.

[0212] When the subarrays being used are close to each other, the device may be able to get better performance (e.g., higher SNR) by using these two links. Therefore, the device may choose to send a joint CSI report in this case, so the device can use these links jointly for subsequent communications. In addition, by sending a joint report, the feedback overhead can be lower.

[0213] In view of the above, in some aspects, the present disclosure relates to multi-link multi-beam channel state feedback for a device that communicates via all links in a set of links. For example, a UE may communicate via multiple links, each of which is associated with a corresponding beam. The UE may communicate with a first TRP via a first link (first beam), communicate with at least one other TRP via at least one second link (at least one second beam), and so on. In this case, the UE may perform feedback operations on each of these links independently, or the UE may perform feedback operations as a group, as discussed above. For example, the UE may use channel state information from one or more links to generate feedback and send it on one or more links.

[0214] In addition, in some aspects, the present disclosure relates to multi-link multi-beam channel state feedback for devices that communicate only on a subset of links in a group of links. For example, a TRP may communicate with a UE via a first link (first beam), and the UE may communicate with at least one other TRP via at least one other link (at least one second beam). In this case, the TRP communicates via a subset of links. In some scenarios, a device (e.g., a TRP) may perform feedback operations on a subset of links independently of feedback operations on other links. In other scenarios, a device may collaborate with at least one other device (e.g., a UE, another TRP, etc.) to perform feedback operations (as discussed above) on one or more links in a group of links. To this end, a device may communicate with another device via another link (e.g., a TRP to TRP channel) to obtain feedback information from the other device (e.g., a joint CSI feedback sent to the other device) or send feedback information to the other device. In addition, the TRP may collaborate to enable the UE to use these links jointly for communication.

[0215] In some aspects, the present disclosure relates to signaling support for multi-link channel state feedback. Here, a device may communicate with another device (or other device) to determine how channel state feedback will be performed. For example, a device may indicate which links are grouped together for channel state feedback, how to perform channel state feedback (e.g., separate reporting or joint reporting) for each link or a group of links, and so on. This signaling can be, for example, from a TRP to a UE, from a UE to a TRP, from a TRP to another TRP, from a UE to another UE, or between other types of devices.

[0216] Example of multi-link beam switching

[0217] In some aspects, the present disclosure relates to communicating beam information in a multi-link scenario. In some cases, the beam information is used for beam switching and / or beam management.

[0218] In beam switching / link management, a device can tell another device that communication can be switched from one link to another, or can request such a switch (e.g., because link quality has degraded or because a better link has been found). Beam switching / link management for multi-link scenarios can be implemented using different schemes.

[0219] In one aspect, the present disclosure is directed to supporting multiple links, where each link performs its own independent beam switching (per-link switching). Thus, in this scenario, a device (e.g., a UE) that is communicating via multiple links performs beam switching for one link independently of beam switching for any other link. For example, a UE may send a message on a particular link to inform the TRP that the UE is switching to another beam or direction (e.g., because link quality has degraded or because a better link has been found).

[0220] On the other hand, the present disclosure relates to supporting beam switching across multiple links (cross-link switching). Here, a link (or a group of links) may indicate beam switching of at least one other link via a control channel. For example, the UE may send a message via the control channel of one link to notify the TRP that beams are being switched for multiple links. As another example, if the active link of the device is lost (e.g., blocked), another link may carry beam switching information (e.g., a beam identifier) ​​to enable the device to switch to another link. These messages may also indicate the time of the switch so that the UE and the TRP can synchronize their switching operations. In addition, confirmation of receipt of a beam switching command in one or more links may be transmitted via another link or links.

[0221] Cross-link switching can potentially reduce the latency associated with beam switching. For example, the handshake associated with the switch (e.g., switching control and recovery procedures) can be carried on another link, thereby reducing the switching time on one or more links subject to the switch. In addition, the TRP can tell the UE to switch links in the next subframe.

[0222] In view of the above, in some aspects, the present disclosure relates to multi-link multi-beam beam switching for a device that communicates via all links in a set of links. For example, a UE may communicate via multiple links, each of which is associated with a corresponding beam, as discussed above. In this case, the UE may perform beam switching on each of these links independently, or the UE may perform beam switching across multiple links (cross-link switching), as discussed above.

[0223] In addition, in some aspects, the present disclosure relates to multi-link multi-beam channel state feedback for devices that communicate only on a subset of links in a set of links. For example, a TRP may communicate with a UE via a first link (a first beam), and the UE may communicate with at least one other TRP via at least one other link (at least one second beam), as discussed above. In some scenarios, a device (e.g., a TRP) may perform beam switching on a subset of links independently of beam switching on other links. In other scenarios, a device may collaborate with at least one other device (e.g., a UE, another TRP, etc.) to perform beam switching across one or more links (cross-link switching). To this end, the device may communicate with another device via another link (e.g., a TRP to TRP channel) to obtain beam switching information (e.g., a beam identifier) ​​from the other device or send beam switching information to the other device.

[0224] In some aspects, the present disclosure relates to signaling support for multi-link channel beam switching. Here, a device may communicate with another device (or other devices) to determine how beam switching will be performed. For example, a device may indicate whether cross-link switching will be used or whether beam switching will be performed independently for each link. This signaling can be, for example, from a TRP to a UE, from a UE to a TRP, from a TRP to another TRP, from a UE to another UE, or between other types of devices.

[0225] Example of multi-link beam restoration

[0226] In some cases, the beam information communicated for a multi-link scenario includes beam recovery information. Once a beam is lost (e.g., blocked), the device may start a beam recovery operation (e.g., a RACH procedure or a scheduling request (SR) procedure) to resynchronize with another device. However, due to the beam loss, the device cannot use the control channel to communicate the beam switch to another device. Beam recovery in a multi-link scenario may be implemented using different schemes.

[0227] In one aspect, the present disclosure is directed to supporting multiple links, where each link performs its own independent beam recovery (per-link recovery). In this case, a device (e.g., a UE) that is communicating via multiple links performs beam recovery for one link independently of beam recovery for any other link. For example, the UE may send a RACH message (on a random access channel) to the TRP to notify the TRP that the UE has lost a link. However, in practice, the RACH procedure may have a relatively high overhead.

[0228] On the other hand, the present disclosure relates to beam recovery across multiple links (cross-link recovery). Here, a link (or a group of links) may be used to recover at least one other link. For example, the UE may send a RACH or SR message to the TRP via a good link (e.g., via the control channel of the link) to notify the TRP that the UE has lost another link (or other link). As another example, the TRP may send a similar message to the UE. Such messages may include various types of beamforming related information or be sent in combination with various types of beamforming related information. For example, the beamforming related information may include an indication of sending new beam pairing information, an indication of a preferred beam, a beam identifier, a specified time for beam switching, confirmation, or other information that facilitates beam recovery.

[0229] In view of the above, in some aspects, the present disclosure relates to multi-link multi-beam beam recovery for a device communicating via all links in a set of links. For example, a UE may communicate via multiple links, each of which is associated with a corresponding beam, as discussed above. In this case, the UE may perform beam recovery on each of these links independently, or the UE may perform beam recovery across multiple links (cross-link recovery), as discussed above.

[0230] In addition, in some aspects, the present disclosure relates to multi-link multi-beam channel state feedback for devices that communicate only on a subset of links in a set of links. For example, a TRP may communicate with a UE via a first link (a first beam), and the UE may communicate with at least one other TRP via at least one other link (at least one second beam), as discussed above. In some scenarios, a device (e.g., a TRP) may perform beam recovery on a subset of links independently of beam recovery on other links. In other scenarios, a device may collaborate with at least one other device (e.g., a UE, another TRP, etc.) to perform beam recovery across one or more links (cross-link recovery). To this end, the device may communicate with another device via another link (e.g., a TRP to TRP channel) to obtain beam recovery information (e.g., a beam identifier) ​​from the other device or send beam recovery information to the other device.

[0231] In some aspects, the present disclosure relates to signaling support for multi-link channel beam restoration. Here, a device may communicate with another device (or other devices) to determine how beam restoration will be performed. For example, a device may indicate whether cross-link restoration will be used or whether beam restoration will be performed independently for each link. This signaling can be, for example, from a TRP to a UE, from a UE to a TRP, from a TRP to another TRP, from a UE to another UE, or between other types of devices.

[0232] Example of Multilink RACH Procedure

[0233] In some cases, the beam information communicated for multi-link scenarios includes random access channel (RACH) information. RACH procedures in multi-link scenarios can be implemented using different schemes.

[0234] In one aspect, the present disclosure is directed to supporting multiple links, each of which performs its own independent RACH procedure. In this case, a device (e.g., a UE) that is communicating via multiple links performs a RACH procedure for one link independently of the RACH procedure for any other link. For example, the UE may send a RACH message (on a random access channel) to the TRP to notify the TRP that the UE has lost a link. However, in practice, the RACH procedure may have a relatively high overhead.

[0235] If a single link is used, the random access channel (RACH) procedure can be used to recover the beam. However, in the case of multiple links, the probability of using RACH is reduced due to possible cross-link recovery. When multiple (e.g., N) links fail, a control signal can be sent on another link to signal the failure event of multiple links simultaneously. For example, the UE can send a RACH message to the TRP to indicate that multiple links have failed.

[0236] Thus, in another aspect, the present disclosure relates to RACH procedures across multiple links.Here, a link (or a group of links) may be used to send control signals for at least one other link.

[0237] In view of the above, in some aspects, the present disclosure relates to a multi-link multi-beam RACH procedure for a device communicating via all links in a set of links. For example, a UE may communicate via multiple links, each of which is associated with a corresponding beam, as discussed above. In this case, the UE may perform a RACH procedure on each of these links independently, or the UE may signal a failure event across multiple links (cross-link recovery), as discussed above.

[0238] In addition, in some aspects, the present disclosure relates to a multi-link multi-beam RACH procedure for a device that communicates only on a subset of links in a set of links. For example, a TRP may communicate with a UE via a first link (a first beam), and the UE may communicate with at least one other TRP via at least one other link (at least one second beam), as discussed above. In some scenarios, a device (e.g., a TRP) may perform a RACH procedure on a subset of links independently of the RACH procedures on other links. In other scenarios, a device may collaborate with at least one other device (e.g., a UE, another TRP, etc.) to signal a fault event across one or more links. To this end, the device may communicate with another device via another link (e.g., a TRP to TRP channel) to obtain fault event information from the other device or send fault event information to the other device.

[0239] In some aspects, the present disclosure relates to signaling support for multi-link channel RACH procedures. Here, a device may communicate with another device (or other device) to determine how the RACH procedure will proceed. For example, a device may indicate whether to perform a RACH procedure independently for each link or whether cross-link signaling of a failure event will be used. This signaling can be, for example, from a TRP to a UE, from a UE to a TRP, from a TRP to another TRP, from a UE to another UE, or between other types of devices.

[0240] Example of multi-link measurement and event triggering

[0241] In some aspects, the present disclosure relates to link measurements (eg, RSRP / RSSI measurements) for multi-link scenarios. Link measurements can be used, for example, for handover or other event triggering.

[0242] In one aspect, the present disclosure relates to supporting multiple links, each of which performs its own measurement and event triggering operations (per link measurements). In this case, a device (e.g., UE) that is communicating via multiple links performs measurement and event triggering operations for one link independently of measurement and event triggering operations for any other link. Here, event triggering (e.g., for switching to a different TRP or link) is based on per link measurements. Therefore, a given device can use multiple triggers, one for each link. In addition, multiple beam measurements can be made for a given link and these measurements can be aggregated (e.g., to compare with a trigger threshold).

[0243] In another aspect, the present disclosure relates to measurement and event-triggered operations across multiple links. Here, a link (or a group of links) may be used for measurement and event triggering of at least one other link. Each trigger may be based on aggregated measurements from multiple links. For example, an event may be triggered based on a comparison of a trigger threshold with a maximum value of measurements from all links in a group. As described above, multiple beam measurements may be made for a given link and these measurements may be aggregated.

[0244] In view of the above, in some aspects, the present disclosure relates to multi-link multi-beam measurement and event-triggered operations for a device that communicates via all links in a set of links. For example, a UE may communicate via multiple links, each of which is associated with a corresponding beam, as discussed above. In this case, the UE may perform measurement and event-triggered operations on each of these links independently, or the UE may perform measurement and event-triggered operations across multiple links, as discussed above.

[0245] In addition, in some aspects, the present disclosure relates to multi-link multi-beam measurement and event triggered operations for a device that communicates only on a subset of links in a set of links. For example, a TRP may communicate with a UE via a first link (a first beam), and the UE may communicate with at least one other TRP via at least one other link (at least one second beam), as discussed above. In some scenarios, a device (e.g., a TRP) may perform measurement and event triggered operations on a subset of links independently of measurement and event triggered operations on other links. In other scenarios, a device may collaborate with at least one other device (e.g., a UE, another TRP, etc.) to perform measurement and event triggered operations across one or more links. To this end, the device may communicate with another device via another link (e.g., a TRP to TRP channel) to obtain measurement information from the other device or send measurement information to the other device.

[0246] In some aspects, the present disclosure relates to signaling support for multi-link channel measurement and event-triggered operations. Here, a device may communicate with another device (or other device) to determine how the measurement and event-triggered operations will be performed. For example, a device may indicate whether to perform measurement and event-triggered operations independently for each link or whether cross-link operations will be used. This signaling can be, for example, from a TRP to a UE, from a UE to a TRP, from a TRP to another TRP, from a UE to another UE, or between other types of devices.

[0248] Fig.14 A block diagram of an example hardware implementation of an apparatus 1400 configured to communicate according to one or more aspects of the present disclosure is illustrated. The apparatus 1400 may be implemented or implemented in a UE, a TRP, a gNB, a base station (BS), or some other type of device that supports wireless communication. In various implementations, the apparatus 1400 may be implemented or implemented in an access terminal, an access point, or some other type of device. In various implementations, the apparatus 1400 may be implemented or implemented in a server, a network entity, a mobile phone, a smart phone, a tablet device, a portable computer, a server, a personal computer, a sensor, an alarm, a vehicle, a machine, an entertainment device, a medical device, or any other electronic device having a circuit system.

[0249] The apparatus 1400 includes a communication interface (e.g., at least one transceiver) 1402, a storage medium 1404, a user interface 1406, a memory device (e.g., a memory circuit) 1408, and a processing circuit 1410 (e.g., at least one processor). In various implementations, the user interface 1406 may include one or more of a keypad, a display, a speaker, a microphone, a touch screen display, or some other circuit system for receiving input from a user or sending output to a user.

[0250] These components can be connected via a signaling bus or other suitable components (by Fig.14 The signaling bus may include any number of interconnecting buses and bridges, depending on the specific application and overall design constraints of the processing circuit 1410. The signaling bus links the various circuits together so that each of the communication interface 1402, the storage medium 1404, the user interface 1406, and the memory device 1408 is coupled and / or in electrical communication with the processing circuit 1410. The signaling bus may also link various other circuits (not shown), such as timing sources, peripherals, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further.

[0251] The communication interface 1402 provides a means for communicating with other devices through a transmission medium. In some implementations, the communication interface 1402 may be adapted to facilitate wireless communication of the device 1400. For example, the communication interface 1402 may include a circuit system and / or programming adapted to facilitate two-way information communication relative to one or more communication devices in the network. Therefore, in some implementations, the communication interface 1402 may be coupled to one or more antennas 1412 for wireless communication within the wireless communication system. In some implementations, the communication interface 1402 may be configured for wired-based communication. For example, the communication interface 1402 may be a bus interface, a send / receive interface, or some other type of signal interface (including a driver, a buffer), or other circuit systems that output and / or obtain signals (e.g., output signals from an integrated circuit and / or receive signals entering an integrated circuit). The communication interface 1402 may be configured with one or more independent receivers and / or transmitters and one or more transceivers. In the illustrated example, the communication interface 1402 includes a transmitter 1414 and a receiver 1416. The communication interface 1402 serves as one example of a receiving device and / or a transmitting device.

[0252] Memory device 1408 may represent one or more memory devices. As indicated, memory device 1408 may maintain link information 1418 along with other information used by apparatus 1400. In some implementations, memory device 1408 and storage medium 1404 are implemented as a shared memory component.

[0253] Storage media 1404 may represent one or more computer-readable, machine-readable, and / or processor-readable devices for storing programming (such as processor-executable code or instructions (e.g., software, firmware), electronic data, databases, or other digital information. Storage media 1404 may also be used to store data manipulated by processing circuit 1410 when executing programming. Storage media 1404 may be any available media that can be accessed by a general or special purpose processor, including portable or fixed storage devices, optical storage devices, and various other media capable of storing, containing, or carrying programming.

[0254] By way of example and not limitation, storage medium 1404 may include: a magnetic storage device (e.g., a hard disk, a floppy disk, a magnetic stripe), an optical disk (e.g., a compact disk (CD) or a digital versatile disk (DVD)), a smart card, a flash memory device (e.g., a memory card, a memory stick, or a key drive), a random access memory (RAM), a read-only memory (ROM), a programmable ROM (PROM), an erasable PROM (EPROM), an electrically erasable PROM (EEPROM), a register, a removable disk, and any other suitable medium for storing software and / or instructions that can be accessed and read by a computer. Storage medium 1404 may be implemented in an article of manufacture (e.g., a computer program product). As an example, a computer program product may include a computer-readable medium in packaging material. In view of the foregoing, in some implementations, storage medium 1404 may be a non-transitory (e.g., tangible) storage medium.

[0255] Storage medium 1404 may be coupled to processing circuit 1410 such that processing circuit 1410 can read information from and write information to storage medium 1404. That is, storage medium 1404 may be coupled to processing circuit 1410 such that storage medium 1404 is at least accessible by processing circuit 1410, including examples in which at least one storage medium is integrated into processing circuit 1410 and / or examples in which at least one storage medium is separate from processing circuit 1410 (e.g., resident in device 1400, external to device 1400, distributed across multiple entities, etc.).

For example, the storage medium 1404 may include operations configured for the following actions: regulating operations at one or more hardware blocks of the processing circuit 1410 and using the communication interface 1402 for wireless communication using its corresponding communication protocol. In some aspects, the storage medium 1404 may include a computer-readable medium storing computer-executable code, including code for performing the functionality described herein.

In some scenarios, the circuit / module 1420 for obtaining may receive information (e.g., from the memory device 1408, the communication interface 1402, or some other component of the apparatus 1400) and process (e.g., decode) the information. In some scenarios (e.g., if the circuit / module 1420 for obtaining is or includes an RF receiver), the circuit / module 1420 for obtaining may receive the information directly from the device transmitting the information. In any case, the circuit / module 1420 for obtaining may output the received information to another component of the apparatus 1400 (e.g., the circuit / module 1422 for determining, the circuit / module 1436 for generating, the memory device 1408, or some other component).

[0264] The circuit / module 1420 for obtaining (e.g., a device for obtaining) can take various forms. In some aspects, the circuit / module 1420 for obtaining can correspond to, for example, a processing circuit, as discussed herein.

For example, the circuit / module 1422 for determining may determine whether to transmit, determine whether to communicate, determine an interaction, determine a type of information, determine whether a power control signal will control transmit power, or determine whether a feedback signal is based on channel state information. The circuit / module 1422 for determining may then output an indication of the determination (e.g., to the circuit / module 1424 for communicating, the circuit / module 1432 for allocating, the memory device 1408, or some other component).

[0267] The circuit / module for communication 1424 may include circuitry and / or programming (e.g., code for communication 1444 stored on storage medium 1404) adapted to perform several functions related to, for example, communicating information. In some implementations, communication involves receiving information. In some implementations, communication involves sending (e.g., transmitting) information.

[0284] In some aspects, the circuit / module 1438 for aggregating may obtain information to be aggregated over a period of time (e.g., from the means for obtaining 1420, the memory device 1408, or some other component). The circuit / module 1438 for aggregating may thus store the information as it is collected (e.g., in the memory device 1408 or some other component).
