Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. patent application No. 18 / 162,475, filed on January 31, 2023, entitled “DYNAMIC RESOURCES FOR SIDELINK COMMUNICATION,” and assigned to the assignee of the present application. The disclosure of the prior application is considered a part of and incorporated by reference into this patent application. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for sidelink communications using dynamic resources. Background Art

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

[0005] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. The UE may communicate with the network node via downlink and uplink communications. A "downlink" (or "DL") refers to the communication link from the network node to the UE, and an "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

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

[0031] A user equipment (UE) can use sidelink resources to communicate with another UE. Sidelink resources can be semi-static resources that follow a configured pattern. With semi-static sidelink resources, a UE knows which beam to use for reception at a given time, and there will be no errors about where the UE is transmitting. However, if there is no traffic from the first UE to the second UE, the allocated semi-static resources from the first UE to the second UE will be wasted.

[0032] According to various aspects described herein, when there is more traffic in a particular direction, the UE may allow more side link resources to be assigned in that direction. The UE may split timing resources into semi-static resources (in a semi-static resource region assigned to semi-static time resources) and dynamic resources (in a dynamic resource region assigned to dynamic time resources). The UE may use the semi-static resource region to maintain a connection at each time, where the beam is fixed and the communication direction (half-duplex mode) is predetermined. The dynamic resource region may be used as needed and may be shared across multiple connections. For example, if the transmitting UE requires more transmission resources, the transmitting UE may request (from the receiving UE) that one or more resources in the dynamic resource region be used for the remainder of the data transmission. In this way, the number of semi-static resources used for each link may be minimized, and signaling resources may be further saved. The semi-static resource region and / or the dynamic resource region may be located in frequency range 2 (FR2). In some aspects, the semi-static region and / or the dynamic region may be located in other frequency ranges, such as FR3, FR4, FR5, or a higher frequency range.

[0033] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout the present disclosure. Rather, these aspects are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of protection of the present disclosure to those skilled in the art. It will be appreciated by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or practice method. Furthermore, the scope of the present disclosure is intended to cover such apparatus or methods implemented using other structures, functionality, or structures and functionality in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the present claims.

[0034] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, or algorithms (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0035] Although various aspects may be described herein using terminology generally associated with 5G or New Radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT, and / or post-5G (e.g., 6G) RATs.

[0036] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (illustrated as network node 110a, network node 110b, network node 110c, and network node 110d), one or more UEs 120 (illustrated as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, meaning that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated base station), meaning that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0037] In some examples, network node 110 is or includes a network node (such as an RU) that communicates with UE 120 via a radio access link. In some examples, network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or communicates with a core network via a backhaul link. In some examples, network node 110 (such as a converged network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. Network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, an RU, a CU, a mobility element of a network, a core network node, a network element, network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 using any suitable transport network via various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks.

[0038] In some examples, network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​network node 110 and / or a network node subsystem serving that coverage area, depending on the context in which the term is used. Network node 110 may provide communication coverage for a macrocell, a picocell, a femtocell, and / or another type of cell. A macrocell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs 120 with service subscriptions. A picocell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscriptions. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 associated with the femtocell (e.g., UEs 120 in a closed subscriber group (CSG)). A network node 110 for a macrocell may be referred to as a macro network node. A network node 110 for a picocell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1In the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0039] In some aspects, the term "base station" or "network node" may refer to a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near-RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions, such as those described herein in conjunction with network node 110. In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions but not another base station function. In this way, a single device may include more than one base station.

[0040] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. Figure 1 In the example shown in , a network node 110 d (e.g., a relay network node) may communicate with a network node 110 a (e.g., a macro network node) and a UE 120 d to facilitate communications between the network node 110 a and the UE 120 d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0041] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0042] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.

[0043] UEs 120 may be dispersed throughout wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device configured to communicate via a wireless or wired medium.

[0044] Some UEs 120 may be considered machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. The UE 120 may be included within a housing that houses components of the UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0045] Generally speaking, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, air interface, etc. A frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0046] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0047] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using one or more operating frequency bands. In 5G NR, two initial operating frequency bands have been identified as frequency ranges designated Frequency Range 1 (FR1) (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). It should be understood that although portions of FR1 are greater than 6 GHz, FR1 is often (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. A similar naming issue sometimes occurs with reference to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0048] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The frequency bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.

[0049] With the above examples in mind, unless otherwise specifically stated, it should be understood that if the term "sub-6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. Additionally, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a, FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0050] In some aspects, a first UE (e.g., UE 120) may include a communications manager 140. As described in greater detail elsewhere herein, the communications manager 140 may select one or more additional resources in a dynamic resource region for a second set of communications to a second UE, the one or more additional resources supplementing the one or more resources in a semi-static resource region for the first set of communications to the second UE. The communications manager 140 may send a request to the second UE to reserve the one or more additional resources for the second set of communications to the second UE. Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0051] In some aspects, a second UE (e.g., UE 120) may include a communications manager 140. As described in greater detail elsewhere herein, the communications manager 140 may perform the following operations: receive a request from a first UE to reserve one or more additional resources in a dynamic resource region for a second set of communications from the first UE to the second UE, the one or more additional resources being in addition to one or more resources in a semi-static resource region used for the first set of communications to the second UE; and send a response to the request to the first UE. Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0052] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0053] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a through 234t, such as T antennas (T ≥ 1). The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R ≥ 1). The network node 110 of example 200 includes one or more radio frequency components, such as antennas 234 and a modem 232. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include radio frequency components, such as one or more CUs or one or more DUs, that facilitate direct communication with the UE 120.

[0054] At network node 110, transmit processor 220 may receive data intended for UE 120 (or a set of UEs 120) from data source 212. Transmit processor 220 may select one or more modulation and coding schemes (MCS) for UE 120 based at least in part on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 may process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120 and may provide data symbols for UE 120. Transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input, multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, as applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a through 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (eg, T downlink signals) via a corresponding set of antennas 234 (eg, T antennas) (shown as antennas 234a through 234t).

[0055] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a through 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use the demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols, if applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to a data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine, among other things, a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter. In some examples, one or more components of the UE 120 may be included in a housing 284.

[0056] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0057] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0058] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from the controller / processor 280. The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, if applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to execute the instructions herein (eg, reference Figures 3 to 12 ) any aspects of any of the methods described.

[0059] At network node 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., a demodulator component (shown as DEMOD) of modem 232), detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include a communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, modem 232 of network node 110 may include a modulator and a demodulator. In some examples, network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to execute the instructions herein (e.g., reference 242). Figures 3 to 12 ) any aspects of any of the methods described.

[0060] As described in greater detail elsewhere herein, a controller / processor of a network entity (e.g., controller / processor 240 of network node 110), controller / processor 280 of UE 120, and / or Figure 2 Any other component of the network node 110 may perform one or more techniques associated with using dynamic resources for sidelink communication. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the may perform or direct e.g. Figure 10 The process of 1000 Figure 11 110 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly or after compilation, conversion, and / or interpretation) by one or more processors of network node 110 and / or UE 120, may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 10 The process of 1000 Figure 11 The process 1100 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among other things.

[0061] In some aspects, a first UE (e.g., UE 120) includes: means for selecting one or more additional resources in a dynamic resource region for a second set of communications to a second UE, the one or more additional resources being in addition to one or more resources in a semi-static resource region for the first set of communications to the second UE; and / or means for sending a request to the second UE to reserve the one or more additional resources for the second set of communications to the second UE. Means for performing the operations described herein for the first UE may include, for example, one or more of the communications manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0062] In some aspects, a second UE (e.g., UE 120) includes: means for receiving a request from a first UE to reserve one or more additional resources in a dynamic resource region for a second set of communications from the first UE to the second UE, the one or more additional resources being in addition to one or more resources in a semi-static resource region used for the first set of communications to the second UE; and / or means for sending a response to the request to the first UE. Means for performing the operations described herein for the second UE may include, for example, one or more of the communications manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0063] Although Figure 2 The blocks in FIG. 2 are illustrated as distinct components, but the functionality described above with respect to these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0064] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0065] The deployment of a communication system such as a 5G NR system can be arranged in a variety of ways with various components or constituent parts. In a 5G NR system or network, a network node, a network entity, a mobility element of the network, a RAN node, a core network node, a network element, a base station or network equipment may be implemented in an aggregated architecture or a decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR base station, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) performing base station functionality may be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. A “network entity” or a “network node” may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs or a combination thereof).

[0066] A converged base station (e.g., a converged network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually spread across one or more other network nodes. The DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), among others.

[0067] Base station type operation or network design may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate scaling of the communication system by separating base station functionality into one or more units that can be deployed separately. A disaggregated base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Each unit of the disaggregated base station may be configured for wired or wireless communication with at least one other unit of the disaggregated base station.

[0068] Figure 3 is a diagram illustrating an example 300 of sidelink communications according to the present disclosure.

[0069] like Figure 3As shown, a first UE 305-1 can communicate with a second UE 305-2 (and one or more other UEs 305) via one or more sidelink channels 310. UEs 305-1 and 305-2 can communicate using one or more sidelink channels 310 for P2P communication, D2D communication, V2X communication (e.g., which may include V2V communication, V2I communication, and / or V2P communication), and / or mesh networking. In some aspects, UEs 305 (e.g., UE 305-1 and / or UE 305-2) can correspond to one or more other UEs described elsewhere herein, such as UE 120. In some aspects, one or more sidelink channels 310 can use a PC5 interface and / or can operate in a high frequency band (e.g., a 5.9 GHz band). Additionally or alternatively, UEs 305 can use Global Navigation Satellite System (GNSS) timing to synchronize the timing of transmit time intervals (TTIs) (e.g., frames, subframes, time slots, or symbols).

[0070] like Figure 3 As further shown, the one or more sidelink channels 310 may include a physical sidelink control channel (PSCCH) 315, a physical sidelink shared channel (PSSCH) 320, and / or a physical sidelink feedback channel (PSFCH) 325. The PSCCH 315 may be used to convey control information, similar to the physical downlink control channel (PDCCH) and / or physical uplink control channel (PUCCH) used for cellular communication with the network node 110 via an access link or access channel. The PSSCH 320 may be used to convey data, similar to the physical downlink shared channel (PDSCH) and / or physical uplink shared channel (PUSCH) used for cellular communication with the network node 110 via an access link or access channel. For example, the PSCCH 315 may carry sidelink control information (SCI) 330, which may indicate various control information for sidelink communication, such as one or more resources (e.g., time resources, frequency resources, and / or spatial resources), wherein a transport block (TB) 335 may be carried on the PSSCH 320. The TB 335 may include data. The PSFCH 325 may be used to communicate sidelink feedback 340, such as hybrid automatic repeat request (HARQ) feedback (eg, acknowledgement or negative acknowledgement (ACK / NACK) information), transmit power control (TPC), and / or scheduling request (SR).

[0071] Although shown on the PSCCH 315, in some aspects, the SCI 330 may include multiple communications in different levels, such as a first-level SCI (SCI-1) and a second-level SCI (SCI-2). SCI-1 may be transmitted on the PSCCH 315. SCI-2 may be transmitted on the PSSCH 320. SCI-1 may include, for example, an indication of one or more resources (e.g., time resources, frequency resources, and / or space resources) on the PSSCH 320, information for decoding sidelink communications on the PSSCH, a quality of service (QoS) priority value, a resource reservation period, a PSSCH DMRS pattern, an SCI format for SCI-2, a beta offset for SCI-2, the number of PSSCH DMRS ports, and / or an MCS. SCI-2 may include information associated with data transmission on the PSSCH 320, such as a HARQ process ID, a new data indicator (NDI), a source identifier, a destination identifier, and / or a channel state information (CSI) report trigger.

[0072] In some aspects, one or more sidelink channels 310 may utilize a resource pool. For example, a scheduling assignment (e.g., included in SCI 330) may be transmitted in a subchannel using specific resource blocks (RBs) across time. In some aspects, a data transmission associated with a scheduling assignment (e.g., on PSSCH 320) may occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some aspects, the scheduling assignment and the associated data transmission are not transmitted on adjacent RBs.

[0073] In some aspects, the UE 305 may operate using a sidelink transmission mode (e.g., Mode 1) in which resource selection and / or scheduling is performed by the network node 110 (e.g., a base station, CU, or DU). For example, the UE 305 may receive a grant for sidelink channel access and / or scheduling from the network node 110 (e.g., directly or via one or more network nodes) (e.g., in downlink control information (DCI) or in a radio resource control (RRC) message, such as a grant for configuration). In some aspects, the UE 305 may operate using a transmission mode (e.g., Mode 2) in which resource selection and / or scheduling is performed by the UE 305 (e.g., rather than the network node 110). In some aspects, the UE 305 may perform resource selection and / or scheduling by sensing channel availability for transmission. For example, UE 305 may measure RSSI parameters associated with various sidelink channels (e.g., sidelink-RSSI (S-RSSI) parameters), may measure RSRP parameters associated with various sidelink channels (e.g., PSSCH-RSRP parameters), and / or may measure RSRQ parameters associated with various sidelink channels (e.g., PSSCH-RSRQ parameters), and may select a channel for sending sidelink communications based at least in part on the measurements.

[0074] Additionally or alternatively, the UE 305 may perform resource selection and / or scheduling using the SCI 330 received in the PSCCH 315, which may indicate occupied resources and / or channel parameters. Additionally or alternatively, the UE 305 may perform resource selection and / or scheduling by determining a channel busy rate (CBR) associated with each sidelink channel, which may be used for rate control (e.g., by indicating a maximum number of resource blocks that the UE 305 may use for a particular set of subframes).

[0075] In a transmission mode in which resource selection and / or scheduling is performed by the UE 305, the UE 305 may generate a sidelink grant and may transmit the grant in the SCI 330. The sidelink grant may indicate, for example, one or more parameters (e.g., transmission parameters) to be used for an upcoming sidelink transmission, such as one or more resource blocks (e.g., for TB 335) to be used for the upcoming sidelink transmission on the PSSCH 320, one or more subframes to be used for the upcoming sidelink transmission, and / or an MCS to be used for the upcoming sidelink transmission. In some aspects, the UE 305 may generate a sidelink grant that indicates one or more parameters for semi-persistent scheduling (SPS), such as the periodicity of the sidelink transmission. Additionally or alternatively, the UE 305 may generate a sidelink grant for event-driven scheduling, such as for on-demand sidelink messages.

[0076] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0077] Figure 4 is a diagram illustrating an example 400 of sidelink and access link communications according to the present disclosure.

[0078] like Figure 4 As shown, the transmitter (Tx) / receiver (Rx) UE 405 and the Rx / Tx UE 410 can communicate with each other via a side link, as described above in conjunction with Figure 4 As further shown, in some sidelink modes, the network node 110 may communicate (e.g., directly or via one or more network nodes), such as via a first access link, with the Tx / Rx UE 405. Additionally or alternatively, in some sidelink modes, the network node 110 may communicate (e.g., directly or via one or more network nodes), such as via a first access link, with the Rx / Tx UE 410. The Tx / Rx UE 405 and / or the Rx / Tx UE 410 may correspond to one or more UEs described elsewhere herein, such as Figure 1 UE 120. Thus, a direct link between UEs 120 (e.g., via a PC5 interface) may be referred to as a side link, and a direct link between network node 110 and UE 120 (e.g., via a Uu interface) may be referred to as an access link. Sidelink communications may be sent via the side link, and access link communications may be sent via the access link. Access link communications may be downlink communications (from network node 110 to UE 120) or uplink communications (from UE 120 to network node 110).

[0079] UE 120 may use carrier aggregation for sidelink channels. Carrier aggregation is a technique that enables two or more component carriers (CCs, sometimes referred to as carriers) to be combined (e.g., into a single channel) for a single UE 120 to increase data capacity. Carriers in the same or different frequency bands may be combined. Additionally or alternatively, contiguous or non-contiguous carriers may be combined. Network node 110 may configure carrier aggregation for UE 120, such as in an RRC message, DCI, and / or another signaling message.

[0080] In some aspects, carrier aggregation may be configured in intra-band contiguous mode, where the aggregated carriers are contiguous with each other and in the same frequency band. In some aspects, carrier aggregation may be configured in intra-band discontiguous mode, where the aggregated carriers are discontiguous with each other and in the same frequency band. In some aspects, carrier aggregation may be configured in inter-band discontiguous mode, where the aggregated carriers are discontiguous with each other and in different frequency bands.

[0081] In carrier aggregation, a UE 120 may be configured with a primary carrier or primary cell (PCell) and one or more secondary carriers or secondary cells (SCells). In some aspects, the primary carrier may carry control information (e.g., DCI and / or scheduling information) for scheduling data communications on one or more secondary carriers, which may be referred to as cross-carrier scheduling. In some aspects, a carrier (e.g., a primary carrier or a secondary carrier) may carry control information for scheduling data communications on that carrier, which may be referred to as self-carrier scheduling or carrier self-scheduling. In some aspects, a carrier aggregation may include multiple secondary carriers (without a primary carrier). Some carrier aggregation configurations may provide CC activation and deactivation, cross-carrier grants (grants for one carrier are provided on another carrier), beam indications, and / or multi-bit feedback.

[0082] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0083] Figure 5 is a diagram illustrating an example 500 of sidelink communications according to the present disclosure.

[0084] For sidelink operation, UE 510 (e.g., UE 120) can connect to one or more other UEs, such as UE 520 (e.g., UE 120) and UE 530 (e.g., UE 120), with unidirectional or bidirectional traffic. For FR1, multiple sidelink connections may not be a problem, as UE 510 can use an omnidirectional antenna pattern to receive the desired signal and select the desired signal from the received signal. However, for FR2, operation is essentially point-to-point at all times, and beam resolution may be required. For the uplink, the network entity (e.g., gNB) can schedule or configure uplink transmissions using certain beams and reserve the network entity's receive beams for reception at the configured / scheduled times. For the downlink, the network entity does not have beam flexibility, at the expense of all UEs pointing toward the network entity and monitoring at all times.

[0085] For FR2, multiple connections may become a problem under analog beam limitations. For a UE with a single panel, the UE cannot receive signals from multiple directions. For example, in order to receive from the intended transmitting UE 520, the receiving UE 510 may need to tune its receive beam towards the direction of UE 520, and therefore UE 510 cannot receive from another transmitting UE 530 in a different direction. That is, the problem is the selection of the beam to be used by UE 510. Example 500 shows three UEs that are actively communicating with each other when they are not in the same beam. It is not clear how multiple side links are maintained in FR2 or millimeter wave (mmW) sidelink operation.

[0086] Example 500 also illustrates semi-static time resources that a UE can use for sidelink communication. Given a collection of UEs with multiple connections, the simplest way to communicate is to dedicate resources at preset locations (times) using preset beams. If there is a connection between UE 510 and UE 520, and there is a transmission from UE 510 to UE 520, a semi-static resource (in the time domain) can be configured so that UE 520 will receive in that resource and use a beam directed toward UE 510. UE 510 may not always need to transmit in the resource and may only need to transmit when there is traffic.

[0087] If PSFCH feedback is configured, then for the PSFCH resources corresponding to the configured resources, if UE 510 transmits to UE 520 in the corresponding PSCCH / PSSCH resources, UE 510 will monitor the PSFCH using the beam directed toward UE 520. There is a potential PSFCH association issue because if one PSFCH opportunity is associated with different time slots when PSSCH uses different beams, it is difficult to tell which beam the PSFCH should use. PSSCH resources can be assigned to correspond to the same PSFCH opportunity in the same direction. If there is bidirectional transmission, semi-static resources from UE 510 to UE 520 and from UE 520 to UE 510 will be used. For large networks, resources can be reused, at least for connections that are relatively far apart from each other. In one example, UE 510 can use resources 532 to transmit to UE 520 and use resources 534 to receive from UE 520. UE 510 may use resources 536 to transmit to UE 530 and use resources 538 to receive from UE 530. UE 520 may use resources 540 to transmit to UE 530 and use resources 542 to receive from UE 530.

[0088] With semi-static sidelink resources, the UE knows which beam to use for reception at a given time, and there are no errors such as UE 510 transmitting to UE 520 while UE 520 is not listening or is listening in the wrong direction. However, semi-static sidelink resources cannot effectively adapt to changes in connectivity and traffic. For example, if there is no traffic from UE 510 to UE 520, the semi-static resources allocated from UE 510 to UE 520 will be wasted.

[0089] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0090] Figure 6 is a diagram illustrating an example 600 of sidelink communication using dynamic resource regions according to the present disclosure.

[0091] According to various aspects described herein, when there is more traffic in a particular direction (beam), the UE may allow more sidelink resources to be assigned in that direction. The UE may split timing resources into semi-static resources (in a semi-static resource region 602 assigned to semi-static time resources) and dynamic resources (in a dynamic resource region 604 assigned to dynamic time resources). The UE may use the semi-static resource region 602 to maintain a connection each time, where the beam is fixed and the communication direction (half-duplex mode) is predetermined. The dynamic resource region 604 may be used as needed and may be shared across multiple connections. The semi-static resource region and / or the dynamic resource region may be located in FR2.

[0092] For example, if data transmission for a connection (e.g., UE 530 to UE 510) is not completed within the semi-static resource region 602 dedicated to the connection, the data transmission may continue in the dynamic resource region 604. That is, if UE 530 requires more transmission resources, UE 530 may request (from UE 510) that one or more resources in the dynamic resource region 604 be used for the remainder of the data transmission. This may involve UE 530 selecting one or more additional resources, such as resource 606 and resource 608 in the dynamic resource region 604, as indicated by reference numeral 610, and sending a request for the one or more additional resources, as indicated by reference numeral 615.

[0093] As indicated by reference numeral 620, UE 510 may send a response. UE 510 may indicate in the response whether the request has been accepted or rejected. UE 510 may indicate in the response one or more proposed resources in dynamic resource region 604 that are different from the requested one or more additional resources. As indicated by reference numeral 625, UE 530 may send communications. UE 530 may use semi-static resources for a first set of (sent) communications and use one or more additional resources (e.g., resources 606 and 608, or granted resources) in dynamic resource region 604 for a second set of (sent) communications. One set of communications may include one or more communications. The first set of communications may include control information. The first set of communications may also include a certain amount of data. The second set of communications may include data. UE 530 may send the second set of communications using the resources proposed by UE 510. By having dynamic resources available for the sidelink (e.g., in FR2), UE 510 may have greater flexibility in resource selection and, therefore, conserve signaling resources.

[0094] In some aspects, the UE 510 may allow only inter-UE coordination (IUC) message exchanges and a small number of data packets in semi-static resources. The small number of data packets may include an amount of data that meets a threshold (e.g., a maximum amount of data). This may include utilizing a mini-slot structure in the semi-static resources to reduce overhead. In this way, the number of semi-static resources used for each link may be minimized, further conserving signaling resources. The IUC message may include a medium access control element (MAC CE) that carries only a PSSCH message or SCI-2 in the PSSCH, neither of which may require a full time slot.

[0095] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0096] Figure 7 is a diagram illustrating an example 700 of a predetermined beam pattern or a half-duplex mode according to the present disclosure.

[0097] In some aspects, for multiple links, the UE may be configured with semi-static resources having a predetermined beam pattern and / or a predetermined half-duplex mode. Example 700 shows an example of a predetermined beam or half-duplex mode 702. The predetermined beam pattern may include a beam direction pattern having peak gain, main lobe properties, and / or side lobe properties. The predetermined half-duplex mode may indicate the transmission direction between UEs for each resource or time slot. Semi-static resources may be configured less frequently than dynamic resources (e.g., with a longer period between configurations) to minimize overhead. The number of time slots / symbols used for each link in the transmit and receive directions may be minimal (e.g., sufficient to maintain the link). However, in order to support higher throughput, dynamic resources may be used. Since semi-static resources may be configured to have a relatively long period between semi-static configurations, in order to minimize scheduling delays when a packet arrives in the middle of the period, it may be better for the UE to use the dynamic resources earlier than the next semi-static reconfiguration.

[0098] There may be multiple links from a UE, either to the same UE or to multiple UEs. In some aspects for multiple links, the UE may configure dynamic resources using some underlying transmit / receive beams and half-duplex modes. The transmitting UE may send a packet in the earliest dynamic resource (e.g., among multiple links) that matches the underlying beam / half-duplex mode. In addition, a UE using a first link among multiple links may convert dynamic resources from a second link between UEs to the first link based at least in part on an IUC message. For example, the dynamic resources identified for the second link may be used for (e.g., copied for) the first link, and information about the dynamic resources may be shared between UEs via an IUC message. By converting the resources to dynamic resources, the beam / half-duplex mode may be changed for the UE.

[0099] When the first link is to use the dynamic resources of the second link, three scenarios are considered. In the first scenario, the first link and the second link have the same receiving UE. The sending UE can request the receiving UE to adjust its receiving beam in advance. The sending UE of the second link can still transmit to the receiving UE, but the receiving beam does not match. In the second scenario, the first link and the second link have the same sending UE, but the sending UE can request the receiving UE to adjust its receiving beam in advance. In the third scenario, the first link and the second link have two pairs of different side link nodes (for example, UE A to UE B and UE C to UE D). For narrow beams, this may not be a problem due to spatial reuse. In some aspects, frequency division multiplexing (FDM) can be used via some cross-link resource reservation.

[0100] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The examples described are different.

[0101] Figure 8 is a diagram illustrating an example 800 of extending a dynamic resource region according to the present disclosure.

[0102] In some aspects, the UE can update or extend the dynamic resource region. In Uu discontinuous reception (DRX), a simple activity timer is used to update resources. This is because the UE will only receive grants from one network entity, so the activity timer is sufficient to expand the resource pool. However, for the FR2 sidelink, the activity timer is no longer sufficient because multiple transmitting UEs may aim to transmit to the receiving UE on the same resource set.

[0103] In some aspects, a UE may use a timer specific to a dynamic resource region to establish and / or extend a dynamic resource region. A dynamic resource region may be extended (made available) for a duration that is as long as the timer is running. The timer may start after a semi-static resource region and end after the expected amount of resources to be used for transmission. Example 800 illustrates the amount of resources in a dynamic resource region extended by a timer for UE 510 and UE 530. If UE 520 does not use such a timer, there may be confusion as to which resources are available in the dynamic resource region.

[0104] As indicated above, Figure 8 are provided as examples. Other examples can be found in the Figure 8 The examples described are different.

[0105] Figure 9 is a diagram illustrating an example 900 of using proposed resources according to the present disclosure.

[0106] In some aspects, to address the dynamic resource conflict issue, UEs can reserve additional dynamic resources and, after the IUC process (exchange of IUC messages between UEs), overwrite the underlying beam and half-duplex mode for the link. From a receiver perspective, overwriting the existing mode can reduce resource conflicts between different links. Example 900 illustrates pre-configured beams and half-duplex modes for a dynamic resource region 604. Within the dynamic resource region 604, resources 902 are used for UE 510 to UE 520, resources 904 are used for UE 520 to UE 510, resources 906 are used for UE 530 to UE 520, resources 908 are used for UE 520 to UE 530, resources 910 are used for UE 510 to UE 530, and resources 912 are used for UE 530 to UE 510.

[0107] As shown at 915, as part of the IUC procedure, UE 510 may request resources 902, 904, and 906 for transmission to UE 520. The request may be via SCI-2 or MAC CE. The request may include the number of additional time slots, the number of subchannels, and / or a preferred quasi-co-located (QCL) state for the requested resources. The request may include a layer 1 (L1) priority and / or a resource selection window (RSW) position. As shown at 920, UE 520 may grant resources 902, 904, and 906 to UE 510.

[0108] As shown by reference numeral 925, UE 530 may request resources 906 for transmission to UE 520. If the request is accepted, UE 530 may proceed with transmission in resources 906. However, UE 520 may have already granted resources 906 to UE 510. It may be helpful for UE 530 to know that resources 906 are unavailable (e.g., whether resources 906 have already been committed by semi-static configuration, or whether resources 906 have already been requested and granted to another UE). If the transmitting UE knows a list of unavailable resources, the request may not include unavailable resources, or unavailable resources may be automatically excluded from the request. Of course, if the underlying beam / half-duplex mode in the dynamic resource region 604 is already consistent with the needs of UE 530 to transmit its packets, UE 530 may not send such a request. Transmitting a request (in this case via the IUC process) provides additional protection for the pre-configured resources in the dynamic resource region 604, as the receiving UE may not grant resources to another transmitting UE.

[0109] The receiving UE may send IUC information indicating acceptance of the resource proposal in the request and / or proposing preferred / non-preferred resources associated with the QCL state. SCI-2 / MAC-CE / PSFCH resources may be used to indicate confirmation and / or propose preferred / non-preferred resources. As shown by reference numeral 930, UE 520 may propose resources 908 to UE 530. In some aspects, such a reverse proposal may include a subset of the resources in the original request. UE 520 may also indicate which resources are unavailable via non-preferred resources. As shown by reference numeral 935, UE 530 may accept the reverse proposal for resources 908. Alternatively, in some aspects, UE 530 may select another resource for another request. That is, UE 520 may use the IUC process with the request and possible reverse proposal to override the existing beam / half-duplex mode for resources 904, 906, and 908.

[0110] As indicated above, Figure 9 are provided as examples. Other examples can be found in the Figure 9 The examples described are different.
