Description

Technical Field

[0001] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for uplink communication prioritization for multiple timing advances. Background Art

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0003] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. The UE may communicate with the network nodes via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, 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.).

[0004] 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, region 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 using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, 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 to better integrate with other open standards; and 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

[0005] Some aspects described herein relate to a user equipment (UE) for wireless communication. The UE may include: a memory; and one or more processors, the one or more processors coupled to the memory. The one or more processors may be configured to: determine that a first uplink communication to be sent overlaps with a second uplink communication to be sent at an overlapping duration in the time domain, the first uplink communication corresponding to a first timing advance (TA) group (TAG) and having a first uplink TA, and the second uplink communication corresponding to a second TAG and having a second uplink TA. The one or more processors may be configured to: send at least a portion of the first uplink communication based at least in part on the first uplink communication satisfying a selection condition, the at least a portion of the first uplink communication including an overlapping portion of the first uplink communication corresponding to the overlapping duration.

The method may include: determining that a first uplink communication to be sent overlaps with a second uplink communication to be sent at an overlapping duration in the time domain, the first uplink communication corresponding to a first TAG and having a first uplink TA, and the second uplink communication corresponding to a second TAG and having a second uplink TA. The method may include: sending at least a portion of the first uplink communication based at least in part on the first uplink communication satisfying a selection condition, the at least a portion of the first uplink communication including an overlapping portion of the first uplink communication corresponding to the overlapping duration.

[0007] Some aspects described herein relate to a non-transitory computer-readable medium storing an instruction set for wireless communication by a UE. The instruction set, when executed by one or more processors of the UE, may cause the UE to determine that a first uplink communication to be sent overlaps with a second uplink communication to be sent at an overlapping duration in the time domain, the first uplink communication corresponding to a first TAG and having a first uplink TA, and the second uplink communication corresponding to a second TAG and having a second uplink TA. The instruction set, when executed by one or more processors of the UE, may cause the UE to send at least a portion of the first uplink communication based at least in part on the first uplink communication satisfying a selection condition, the at least a portion of the first uplink communication including an overlapping portion of the first uplink communication corresponding to the overlapping duration.

[0008] Some aspects described herein relate to an apparatus for wireless communication. The apparatus may include a component for determining that a first uplink communication to be sent overlaps with a second uplink communication to be sent at an overlapping duration in the time domain, the first uplink communication corresponding to a first TAG and having a first uplink TA, and the second uplink communication corresponding to a second TAG and having a second uplink TA. The apparatus may include a component for sending at least a portion of the first uplink communication based at least in part on the first uplink communication satisfying a selection condition, the at least a portion of the first uplink communication including an overlapping portion of the first uplink communication corresponding to the overlapping duration.

[0019] The 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 interpreted as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art.

[0021] The present disclosure may be easily used as a basis for modifying or designing other structures for performing the same purpose of the present disclosure. Such equivalent constructions do not depart from the scope of the appended claims. The characteristics of the concepts disclosed herein (both their organization and method of operation) and the associated advantages are better understood from the following description when considered in conjunction with the accompanying drawings. Each of the figures in the accompanying drawings is provided for the purpose of illustration and description and not as a definition of the limitations of the claims.

[0022] Although various aspects are described in the present disclosure by illustrating some examples, such aspects can be implemented in many different arrangements and scenarios. The technology described herein can be implemented using different platform types, devices, systems, shapes, sizes and / or packaging arrangements. For example, some aspects can be implemented via integrated chip implementations or other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / shopping equipment, medical equipment and / or artificial intelligence devices). Various aspects can be implemented in chip-level components, modular components, non-modular components, non-chip-level components, device-level components and / or system-level components. The equipment incorporating the various aspects and features described may include additional components and features for implementing and practicing the various aspects claimed and described. For example, the transmission and reception of wireless signals may include one or more components (e.g., hardware components, including antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processors, interleavers, adders and / or summers) for analog and digital purposes. Various aspects described herein can be practiced in various devices, components, systems, distributed arrangements and / or end-user devices of different sizes, shapes and compositions.

[0023] 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, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0024] Although various aspects may be described herein using terms 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 RATs beyond 5G (e.g., 6G).

[0025] Figure 11 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 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown 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, which means 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 decomposed network node (sometimes referred to as a decomposed base station), which means 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)).

[0026] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link, such as a CU. In some examples, the network node 110 (such as an aggregated 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. The 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, a RU, a CU, a mobility element of a network, a core network node, a network element, a 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 via various types of fronthaul, midhaul, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks, using any suitable transport network.

[0027] In some examples, the 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 ​​the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell 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 1 In the example shown in , 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, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0028] 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 the network node 110. In some aspects, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of 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 repeat the performance of 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 the other. In this way, a single device may include more than one base station.

[0029] 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 is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown in , a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communication between the network node 110a and the UE 120d. 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.

[0030] 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).

[0031] 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 or wired backhaul communication link. In some aspects, the network controller 130 may be, or may include, a CU or a core network device.

[0032] UE 120 may be dispersed throughout the 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 smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, 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 a 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, an 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.

[0033] Some UEs 120 may be considered as 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 may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of 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, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0034] In general, 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. RAT may be referred to as a radio technology, air interface, etc. 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.

[0035] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may 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 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0036] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "below 6 GHz" band in various documents and articles. A similar naming problem sometimes occurs with respect 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).

[0037] 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 bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, so 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 operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz-71 GHz), FR4 (52.6GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0038] With the above examples in mind, unless otherwise specifically stated, it should be understood that if the term "below 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 or 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.

[0039] In some aspects, the UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may determine that a first uplink communication to be sent overlaps with a second uplink communication to be sent at an overlapping duration in the time domain, the first uplink communication corresponding to a first timing advance (TA) group (TAG) and having a first uplink TA, and the second uplink communication corresponding to a second TAG and having a second uplink TA; and send at least a portion of the first uplink communication based at least in part on the first uplink communication satisfying a selection condition, the at least a portion of the first uplink communication including an overlapping portion of the first uplink communication corresponding to the overlapping duration. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0040] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0041] Figure 22 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 to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. 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 a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0042] At the network node 110, a transmit processor 220 may receive data intended for a UE 120 (or a set of UEs 120) from a data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The 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, where 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 to 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).

[0043] At the UE 120, a set of antennas 252 (shown as antennas 252a to 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 to 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 a 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 where 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 the 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 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, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0044] 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.

[0045] 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 (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may 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.

[0046] Each of the antenna elements may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element that is cross-polarized with a second sub-element, which can be used to independently transmit cross-polarized signals. The antenna elements may include patch antennas, dipole antennas, or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements may allow signals having a desired wavelength transmitted individually by the antenna elements to interact or interfere (e.g., to form a desired beam). For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half wavelength, or other fraction of a wavelength of the spacing between adjacent antenna elements to allow interaction or interference of signals transmitted by individual antenna elements within the desired range.

[0047] Antenna elements and / or sub-elements may be used to generate beams. A "beam" may refer to a directional transmission, such as a wireless signal transmitted in the direction of a receiving device. A beam may include a directional signal, a direction associated with the signal, a set of directional resources associated with the signal (e.g., angle of arrival, horizontal direction, vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal.

[0048] As indicated above, antenna elements and / or sub-elements can be used to generate beams. For example, antenna elements can be individually selected or deselected for transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers. Beamforming includes generating beams using multiple signals on different antenna elements, wherein one or more or all of the multiple signals are shifted in phase relative to each other. The formed beams can carry physical or higher layer reference signals or information. When each of the multiple signals is radiated from the corresponding antenna element, the radiated signals interact, interfere (constructively and destructively) and amplify with each other to form the resulting beam. The shape (such as amplitude, width and / or the presence of side lobes) and direction (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shift or phase offset of the multiple signals relative to each other.

[0049] Beamforming may be used for communication between a UE and a base station, such as for millimeter wave communication, etc. In such a case, the base station may provide the UE with a configuration of a transmit configuration indicator (TCI) state, which respectively indicates beams that may be used by the UE, such as for receiving a physical downlink shared channel (PDSCH). The base station may indicate the activated TCI state to the UE, and the UE may use the activated TCI state to select a beam for receiving the PDSCH.

[0050] The beam indication may be or include a TCI state information element, a beam identifier (ID), spatial relationship information, a TCI state ID, a closed loop index, a panel ID, a TRP ID, and / or a sounding reference signal (SRS) set ID, etc. A TCI state information element (referred to herein as TCI state) may indicate information associated with a beam, such as a downlink beam. For example, the TCI state information element may indicate a TCI state identifier (e.g., tci-StateID), a quasi co-location (QCL) type (e.g., qcl-Typel, q cl-Type2, qcl-TypeA, qcl-TypeB, qcl-TypeC, qcl-TypeD, etc.), cell identifier (e.g., ServCellIndex), bandwidth part identifier (bwp-Id), reference signal identifier (such as CSI-RS (e.g., NZP-CSI-RS-ResourceId, SSB-Index, etc.)), etc. The spatial relationship information may similarly indicate information associated with an uplink beam.

[0051] The beam indication may be a joint or separate downlink (DL) / uplink (UL) beam indication in a unified TCI framework. In some cases, the network may support layer 1 (L1) based beam indication using at least UE-specific (unicast) downlink control information (DCI) to indicate a joint or separate DL / UL beam indication from an active TCI state. In some cases, existing DCI formats 11 and / or 12 may be reused for beam indication. The network may include a support mechanism for the UE to confirm successful decoding of the beam indication. For example, an acknowledgement / negative acknowledgement (ACK / NACK) of a PDSCH scheduled by a DCI carrying a beam indication may also be used as an ACK for the DCI.

[0052] Beam indication may be provided for carrier aggregation (CA) scenarios. In a unified TCI framework, the network may support common TCI state ID updates and activations to provide common QCL information and / or one or more common UL transmit spatial filters across a set of configured component carriers (CCs). This type of beam indication may be applicable to intra-band CA as well as joint DL / UL beam indication and separate DL / UL beam indication. A common TCI state ID may mean that a reference signal (RS) determined according to a TCI state indicated by a common TCI state ID is used to provide a QCL type D indication and determine a UL transmit spatial filter across a set of configured CCs.

[0053] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). 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, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent 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 perform the functions described herein (eg, with reference to Figures 4 to 6 ) or any aspect of any of the methods described herein.

[0054] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the 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 perform operations described herein (e.g., with reference to Figures 4 to 6 ) or any aspect of any of the methods described herein.

[0055] In some aspects, the controller / processor 280 may be a component of a processing system. A processing system may generally be a system or series of machines or components that receives inputs and processes the inputs to produce a set of outputs that may be communicated to other systems or components, such as the UE 120. For example, the processing system of the UE 120 may be a system that includes various other components or subcomponents of the UE 120.

[0056] The processing system of UE 120 may interface with one or more other components of UE 120, may process information (such as input or signal) received from one or more other components, or may output information to one or more other components. For example, a chip or modem of UE 120 may include: a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, sending, or providing information. In some examples, the first interface may be an interface between a processing system and a receiver of the chip or modem, so that UE 120 may receive information or signal input, and may pass information to the processing system. In some examples, the second interface may be an interface between a processing system and a transmitter of the chip or modem, so that UE 120 may send information output from the chip or modem. A person of ordinary skill in the art will readily recognize that the second interface may also obtain or receive information or signal input, and the first interface may also output, send, or provide information.

[0057] In some aspects, controller / processor 240 may be a component of a processing system. A processing system may generally be a system or series of machines or components that receives inputs and processes the inputs to produce a set of outputs that may be passed to other systems or components, such as network node 110. For example, a processing system of network node 110 may be a system that includes various other components or subcomponents of network node 110.

[0058] The processing system of the network node 110 may interface with one or more other components of the network node 110, may process information (such as input or signal) received from one or more other components, or may output information to one or more other components. For example, a chip or modem of the network node 110 may include: a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, sending, or providing information. In some examples, the first interface may be an interface between a processing system and a receiver of the chip or modem, so that the network node 110 may receive information or signal input, and may pass information to the processing system. In some examples, the second interface may be an interface between a processing system and a transmitter of the chip or modem, so that the network node 110 may send information output from the chip or modem. A person of ordinary skill in the art will readily recognize that the second interface may also obtain or receive information or signal input, and the first interface may also output, send, or provide information.

[0059] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of 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 Figure 5 10 and / or operations of process 500 and / or 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 by one or more processors of network node 110 and / or UE 120 (e.g., directly, or after compilation, conversion and / or interpretation), may cause the one or more processors, UE 120 and / or network node 110 to perform or direct, for example, Figure 5 The process 500 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, etc.

[0060] In some aspects, a UE (e.g., UE 120) includes a component for determining that a first uplink communication to be sent overlaps with a second uplink communication to be sent at an overlapping duration in the time domain, the first uplink communication corresponding to a first TAG and having a first uplink TA, and the second uplink communication corresponding to a second TAG and having a second uplink TA; and / or a component for sending at least a portion of the first uplink communication based at least in part on the first uplink communication satisfying a selection condition, the at least a portion of the first uplink communication including an overlapping portion of the first uplink communication corresponding to the overlapping duration. The components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0061] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for 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.

[0062] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0063] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can 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. "Network entity" or "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).

[0064] An aggregated base station (e.g., an aggregated 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, a 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 distributed across one or more other network nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a 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), and the like.

[0065] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed 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 the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed 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. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0066] Figure 3 300 is a diagram illustrating an example of multiple TRP (mTRP) operation based on multiple DCI according to the present disclosure. As shown, UE 305 can communicate with a first TRP 310 and a second TRP 315. UE 305 can be configured with mTRP operation based on multiple DCI. In some aspects, TRP 310 and / or TRP 315 can be a combination of the above Figure 1 and Figure 2 The one or more network nodes 110 described herein include, include, or are included in the one or more network nodes. For example, different TRPs 310 and 315 may be included in different network nodes 110. In some cases, multiple TRPs 310 and 315 may be included in a single network node 110. In some cases, TRP 310 and / or TRP 315 may be referred to as a cell, panel, antenna array, or array. UE 305 may be a combination of the above. Figure 1 and Figure 2 The described UE 120 includes or is included in the UE.

[0067] In some aspects, multiple TRPs 310 and 315 may transmit communications (e.g., the same communication or different communications) in the same transmit time interval (TTI) (e.g., time slot, mini-slot, subframe, or symbol) or in different TTIs using different QCL relationships (e.g., different spatial parameters, different TCI states, different pre-coding parameters, or different beamforming parameters). In some aspects, the TCI state may be used to indicate one or more QCL relationships. A TRP 310 may be configured to serve traffic to a UE 305 individually (e.g., using dynamic selection) or jointly (e.g., using joint transmission with one or more other TRPs 310).

[0068] UE 305 may be configured with multi-DCI based mTRP operation. As shown, when configured with multi-DCI based multi-TRP operation, UE 305 may receive a first DCI transmission 320 from a first TRP 310 in a first physical downlink control channel (PDCCH) (shown as "PDCCH1"), wherein the first DCI transmission 320 may schedule a first physical downlink shared channel (PUSCH) transmission 325 for transmission to the first TRP 310. Similarly, UE 305 may receive a second DCI transmission 330 from a second TRP 315 in a second PDCCH (shown as "PDCCH2"), wherein the second DCI transmission 330 may schedule a second PUSCH transmission 335 for transmission to the second TRP 315. In some cases, the first DCI transmission 320 may schedule a first PDSCH transmission, and the second DCI transmission 330 may schedule a second PDSCH transmission. In association with monitoring the DCI sent from the first TRP 310 and the second TRP 315, the UE 305 may monitor PDCCH candidates in PDCCH monitoring opportunities configured by the network in a certain number of different resource set (CORESET) pools.

[0069] In some cases, the first TRP 310 may be associated with a serving cell of the UE 305. For example, the first TRP 310 may be a base station providing a serving cell or a relay device providing access to the serving cell. In some cases, a certain number of additional TRPs may be associated with a certain number of additional serving cells. In some cases, the second TRP 315 may be associated with a non-serving cell. In order to communicate with the cell and receive DCI transmissions, the UE 305 may obtain a beam indication for beam selection based on the TCI state. In some cases, synchronization signal block (SSB) information may be used to perform channel measurements, obtain TCI states, or select beams for communication. The UE 305 may obtain SSB transmission positioning, SSB transmission periodicity, and SSB transmission power associated with the cell, and use this information to facilitate reception and decoding of DCI transmissions.

[0070] In some scenarios such as dual connectivity and / or carrier aggregation, different cells or uplink carriers may be configured in different TAGs. A TAG may refer to a set of uplink carriers having the same (or similar within a threshold) TA value. For example, a first uplink carrier and a second uplink carrier may have different propagation delays between the UE 305 and the TRP 310 and between the UE 305 and the TRP 315, respectively. For example, a first serving cell (e.g., a primary cell (PCell)) for a first uplink carrier may be associated with a first TRP 310, and a second serving cell (e.g., a SCell) for a second uplink carrier may be associated with a second TRP 315 that is not co-located with the first TRP 310, resulting in different propagation delays for uplink transmissions to arrive at corresponding TRPs 310 or 315 on different uplink carriers. Therefore, the first uplink carrier and the second uplink carrier may have different TA values ​​for uplink transmissions and may belong to different TAGs.

[0071] UE 305 may use the TA value for an uplink carrier to send uplink communications on the uplink carrier with timing that synchronizes the TTI with TRP 310 or 315 to reduce inter-TTI interference.

[0072] The uplink carriers may be transmitted asynchronously or synchronously. Two or more uplink carriers are typically synchronized when transmitted in the same subband. When a single TA command is used to control the timing of two or more uplink carriers, the two or more uplink carriers may be transmitted synchronously. The transmission of two or more uplink carriers may be considered asynchronous with respect to each other when the transmission of one of the carriers lags behind the transmission of another of the carriers.

[0073] Multiple TAGs may be defined for UE 305, which may be configured for carrier aggregation. A TAG typically includes one or more uplink carriers controlled by the same TA command sent from TRP 310 and / or 315. The TAG may be configured by the serving TRP using dedicated signaling. A PDCCH command directed to an activated secondary cell in a TAG may initiate a random access procedure, which may result in the use of a physical random access channel (PRACH). For example, a PDCCH command may be used after UL resources and DL resources have been released and TRP 315 has DL data to be transmitted to UE 305.

[0074] When multiple TAGs are defined for the UE 305, there may be timing differences between uplink carriers transmitted by the UE 305 because one or more TAGs may have received a TA command that is different from the TA command received by other TAGs. The TA command may cause two or more TAGs to have different timing offsets from each other, and these timing differences may be characterized as relative delays between a pair of TAGs or between corresponding component carriers, subframes, and / or symbols within the pair of TAGs.

[0075] In some cases, UE 305 may follow the downlink frame timing changes of a cell in a connected state (which may be referred to as a "reference cell"). The uplink frame transmission may occur before (in time) the first detected path of receiving the corresponding downlink frame from the reference cell (N TA +N TAoffset )*T c , where N TA is the TA value obtained from the TA command, N TAofffset is the TA offset value, and T c is a time unit. For a serving cell in a primary TAG, the UE 305 may use a special cell (SpCell) as a reference cell for deriving the UE transmit timing of the cell in the primary TAG. For a serving cell in a secondary TAG, the UE 305 may use any one of the activated secondary cells as a reference cell to derive the UE transmit timing for the cell in the secondary TAG.

[0076] For example, the UE may be configured to handle at least the relative timing difference between the slot timings of all pairs of one or more specified TAGs, assuming that the UE is configured with a primary TAG and a secondary TAG for inter-band NR carrier aggregation in standalone mode or dual connectivity mode and / or is configured with more than one secondary TAG for inter-band NR carrier aggregation in dual connectivity mode. For intra-band non-contiguous NR carrier aggregation, the UE may be able to handle at least the relative receive timing difference between the slot timings of different carriers to be aggregated at the UE. For inter-band NR carrier aggregation, the UE may be able to handle at least the relative receive timing difference between the slot timings of all pairs of carriers to be aggregated at the UE.

[0077] In some cases, as shown in the figure, two uplink communications can be continuously scheduled according to logical time. However, once the corresponding uplink TA is applied, the actual uplink timing associated with the corresponding communication of time slot 340 may be offset. For example, the uplink timing of the communication associated with the first TAG (TAG 1) may be offset relative to the logical time and relative to the uplink timing of the communication associated with the second TAG (TAG2). The first TAG may be associated with TRP 310, for example, and the second TAG may be associated with TRP 315. The first uplink communication may overlap with the second uplink communication in the overlapping duration 345. In some cases, the length of the overlapping duration 345 may be one or more symbols 340. In some cases, the length of the overlapping duration 345 may be a partial symbol 340 (as shown in the figure). In some cases, UE 305 may not be able to simultaneously transmit two uplink communications on the same CC or different CCs.

[0078] In some cases, discard rules may be used to handle overlaps between two UL transmissions associated with different TAGs. For example, a rule may include discarding an overlapping portion or the entire transmission of an UL transmission that starts later in logical time or actual time, or discarding an overlapping portion or the entire transmission of an UL transmission associated with a specific TRP. However, the DMRS may be located at the beginning of an uplink communication. Therefore, if the overlapping portion of an uplink communication that occurs later is discarded, the DMRS may be discarded, thereby negatively affecting the demodulation and decoding performance of the network.

[0079] Some aspects of the technology described herein provide DMRS-aware prioritization of multiple uplink communications associated with multiple TAGs. In some aspects, for example, a UE may determine that two overlapping uplink communications (e.g., channels and / or signals) associated with different TAGs are to be sent in the same CC or different CCs. A first uplink communication may be associated with a first TAG, and a second uplink communication may be associated with a second TAG. The first uplink communication and the second uplink communication and their corresponding timing may be determined to overlap based on applying a corresponding TA for each uplink communication. In some aspects, a UE may determine which of the two uplink communications to send based at least in part on satisfying a sending condition. The sending condition may be based on the presence of a DMRS symbol in one or more uplink communications in the uplink communication. For example, in some aspects, a UE may determine which of the uplink communications to send based on the presence of a DMRS symbol in an overlapping portion in one or more uplink communications in the uplink communication. The determination may affect the non-overlapping portion (e.g., symbols and / or partial symbols) of the uplink communications, or may not affect the non-overlapping portion (e.g., symbols and / or partial symbols) of the uplink communications. In this way, some aspects may facilitate the selection of uplink communications to be sent in overlapping scenarios without unnecessarily discarding DMRS. Therefore, some aspects may have a positive impact on network performance (including, for example, uplink transmission performance, demodulation performance, and decoding performance).

[0080] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0081] Figure 4 4 is a diagram illustrating an example associated with uplink communication prioritization for multiple TAs according to the present disclosure. As shown, UE 402 can communicate with network node 404. Network node 404 can include any number of TRPs, such as, for example, a first TRP and a second TRP, each of which can correspond to a respective TAG. In some aspects, UE 402 can be similar to Figure 3 UE 305 shown in . In some aspects, network node 404 can be similar to TRP 310 and / or TRP 315.

[0082] As shown by reference numeral 406, UE 402 may determine that a first uplink communication to be sent overlaps with a second uplink communication to be sent at an overlap duration 408 in the time domain. The first uplink communication may correspond to a first TAG and may have a first uplink TA. The second uplink communication may correspond to a second TAG and have a second uplink TA. The first uplink communication and the second uplink communication may be determined after applying UCI multiplexing rules, UL drop rules, and resolving TDD-related DL-UL conflicts.

[0083] As shown by reference numeral 410, based at least in part on the first uplink communication satisfying the selection condition, the UE 402 may send at least a portion of the first uplink and the network node 404 may receive at least a portion of the first uplink. The at least a portion of the first uplink communication may include an overlapping portion 412 of the first uplink communication corresponding to the overlapping duration 408.
