Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Patent Application No. 17 / 816,125, filed on July 29, 2022, entitled “RESOURCE SKIPPING FORMULTIPLE GRANTS” and assigned to the assignee of this patent application. The disclosure of the prior application is considered a part of this patent application and is 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 skipping resources for multiple grants. Background Art

[0004] 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).

[0005] A wireless network may include one or more base stations that support communications for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink communications and uplink communications. A "downlink" (or "DL") refers to the communication link from a base station to a UE, and an "uplink" (or "UL") refers to the communication link from a UE to a base station.

[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, 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 using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink, using 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, and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. 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

[0037] 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. On the contrary, 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. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods implemented using other structures, functions, or structures and functions 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 claims.

[0038] 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 can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0039] 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 post-5G RATs (e.g., 6G).

[0040] 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 a user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e). The wireless network 100 may also include one or more network entities, such as a base station 110 (shown as BS110a, BS110b, BS 110c, and BS110d) and / or other network entities. The base station 110 is a network entity that communicates with the UE 120. Base station 110 (sometimes referred to as BS) 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, and / or a transmit receive point (TRP). Each base station 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to a coverage area of ​​a base station 110 and / or a base station subsystem serving the coverage area, depending on the context in which the term is used.

[0041] The base station 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 base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or a home base station. In Figure 1In the example shown in , BS 110a may be a macro base station for macro cell 102a, BS 110b may be a pico base station for pico cell 102b, and BS 110c may be a femto base station for femto cell 102c. A base station may support one or more (eg, three) cells.

[0042] In some examples, the cell may not necessarily be fixed, and the geographic area of ​​the cell may move according to the location of the mobile base station 110 (e.g., a mobile base station). In some examples, the base stations 110 may be interconnected with each other and / or to one or more other base stations 110 or network entities in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0043] In some aspects, the term "base station" (e.g., base station 110) or "network entity" may refer to a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, and / or one or more components thereof. For example, in some aspects, a "base station" or "network entity" may refer to a central unit (CU), a distributed unit (DU), a radio unit (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 entity" may refer to one device configured to perform one or more functions, such as those described herein in conjunction with base station 110. In some aspects, the term "base station" or "network entity" 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 geographical location or different geographical 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 entity" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network entity" may refer to one or more virtual base stations and / 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 entity" 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.

[0044] The wireless network 100 may include one or more relay stations. A relay station is a network entity that can receive data transmissions from an upstream station (e.g., a network entity or UE 120) and transmit the data transmissions to a downstream station (e.g., a UE 120 or a network entity). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1In the example shown in FIG. 1 , BS 110d (eg, a relay base station) may communicate with BS 110a (eg, a macro base station) and UE 120d to facilitate communication between BS 110a and UE 120d. Base station 110 that relays communication may be referred to as a relay station, relay base station, relay, or the like.

[0045] The wireless network 100 may be a heterogeneous network having network entities including different types of BSs, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations 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 base station may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico base station, a femto base station, and a relay base station may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0046] The network controller 130 may be coupled to or in communication with a set of network entities and may provide coordination and control for these network entities. The network controller 130 may communicate with the base station 110 via a backhaul communication link. The network entities may also communicate directly with each other or indirectly via a wireless or wired backhaul communication link.

[0047] UE 120 may be distributed 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 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, and / or any other suitable device configured to communicate via a wireless medium.

[0048] 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, which may communicate with a network entity, 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.

[0049] 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.

[0050] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using a network entity as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, 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 base station 110.

[0051] 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 portions of FR1 are greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 6 GHz” band in various documents and articles. Similar naming issues sometimes occur with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0052] The 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, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, currently exploring higher frequency bands to extend 5G NR operation to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designation 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.

[0053] In view of the above examples, 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. In addition, 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.

[0054] In some aspects, UE 120 may include a communication manager 140. As described in greater detail elsewhere herein, the communication manager 140 may select, for communications on a physical uplink channel, a first resource to be skipped in each of a plurality of grant opportunities. The communication manager 140 may send uplink control information (UCI) indicating the first resource or a second resource to be not skipped in each of the plurality of grant opportunities. The communication manager 140 may use the second resource instead of the first resource to send communications in the plurality of grant opportunities. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0055] In some aspects, a network entity (e.g., base station 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may receive a UCI indicating a first resource or a second resource of a plurality of grant opportunities, the first resource in each grant opportunity being used first for communication on a physical uplink channel, and the second resource not being skipped. The communication manager 150 may receive communications in the plurality of grant opportunities, and decode communications in the second resource and not decode communications in the first resource based at least in part on the UCI. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0056] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0057] Figure 2 2 is a diagram illustrating an example 200 of a network entity (e.g., base station 110) communicating with UE 120 in a wireless network 100 according to the present disclosure. Base station 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1).

[0058] At the base station 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the 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 (CQI) received from the UE 120. The base station 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., pre-coding) 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 up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0059] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the base station 110 and / or other base stations 110, and a set of received signals (e.g., R received signals) may be provided 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.

[0060] 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 network entities via the communication unit 294.

[0061] 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.

[0062] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by a TX MIMO processor 266, where applicable, further processed by a modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to a network entity. 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 (e.g., a controller / processor 280) and a memory 282 to perform the operations described herein (e.g., reference 1). Figures 4 to 19 ) or any aspect of any of the methods described herein.

[0063] At a network entity (e.g., base station 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 of modem 232 shown as DEMOD), detected by MIMO detector 236 (where applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide decoded data to data sink 239 and decoded control information to controller / processor 240. The network entity may include a communication unit 244 and may communicate with network controller 130 via communication unit 244. The network entity may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the network entity may include a modulator and a demodulator. In some examples, the network entity 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 configured by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 4 to 19 ) or any aspect of any of the methods described herein.

[0064] A controller / processor of a network entity (e.g., controller / processor 240 of base station 110), controller / processor 280 of UE 120, and / or Figure 2 Any other components of the base station 110 may perform one or more techniques associated with utilizing a single UCI to indicate resources for which multiple grant opportunities are to be skipped, as described in detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of may perform or direct e.g. Fig.16 The process of 1600 Fig.17 1700 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network entities 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, one or more instructions, when executed by one or more processors of the network entity and / or UE 120 (e.g., directly executed, or executed after compilation, conversion, and / or interpretation), may cause one or more processors, UE 120, and / or the network entity to perform or direct, for example, Fig.16 The process of 1600 Fig.17 The process 1700 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.

[0065] In some aspects, the UE 120 includes: a component for selecting a first resource to be skipped in each of a plurality of grant opportunities for communication on a physical uplink channel; a component for sending a UCI indicating the first resource or a second resource to be not skipped in each of a plurality of grant opportunities; and / or a component for sending communication in a plurality of grant opportunities using the second resource instead of the first resource. The components for the UE 120 to perform the operations described herein may include, for example, one or more of the following: the communication 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.

[0066] In some aspects, a network entity (e.g., base station 110) includes: a component for receiving UCI indicating a first resource or a second resource of a plurality of grant opportunities, the first resource in each grant opportunity being used first for communication on a physical uplink channel, and the second resource not being skipped. A component for receiving communication in a plurality of grant opportunities; and / or a component for decoding the communication in the second resource based at least in part on the UCI and not decoding the communication in the first resource. In some aspects, the components for the network entity to perform the operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0067] 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.

[0068] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0069] Figure 3 is a diagram illustrating an example of a decomposed base station 300 according to the present disclosure.

[0070] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts 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 radio access network (RAN) node, a core network node, a network element or a network equipment (such as a base station, or one or more units (or one or more components) performing base station functionality) can be implemented in an aggregated architecture or a decomposed architecture. For example, a BS (such as a Node B, an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) can be implemented as an aggregated base station (also called an independent BS or a monolithic BS) or a decomposed base station.

[0071] A converged base station may be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node. A decomposed base station may be configured to utilize a protocol stack 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 aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed in one or more other RAN 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 (e.g., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU)).

[0072] Base station type operations or network designs 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)). Decomposition may include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which may enable flexibility in network design. Individual units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0073] The decomposed base station 300 architecture may include one or more CUs 310 that may communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 through one or more decomposed base station units (such as a near RTRIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via corresponding midhaul links (such as an F1 interface). The DU 330 may communicate with one or more RUs 340 via corresponding fronthaul links. Fronthaul links, midhaul links, and backhaul links may generally be referred to as "communication links." The RU 340 may communicate with a corresponding UE 120 via one or more RF access links. In some aspects, a UE 120 may be served by multiple RUs 340 simultaneously. The DU 330 and the RU 340 may also be referred to as "O-RAN DU (O-DU") and "O-RAN RU (O-RU)", respectively. The network entity may include a CU, DU, RU, or any combination of CU, DU, and RU. The network entity may include a decomposed base station or one or more components of a decomposed base station, such as a CU, DU, RU, or any combination of CU, DU, and RU. The network entity may also include one or more of a TRP, a relay station, a passive device, an intelligent reflective surface (IRS), or other components that may provide a network interface or service for a UE, a mobile station, a sensor / actuator, or other wireless device.

[0074] Each of these units (e.g., CU 310, DU 330, RU 340, and near-RT RIC 325, non-RT RIC 315, and SMO framework 305) may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of these units or an associated processor or controller that provides instructions to the communication interface of these units may be configured to communicate with one or more of the other units via a transmission medium. For example, these units may include a wired interface configured to receive or send signals to one or more of the other units via a wired transmission medium. Additionally, a unit may include a wireless interface that may include a receiver, a transmitter, or a transceiver (such as an RF transceiver) configured to receive or send signals, or both, to one or more of the other units on a wireless transmission medium.

[0075] In some aspects, CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function can be implemented using an interface that is configured to communicate signals with other control functions hosted by CU 310. CU310 may be configured to handle user plane functionality (i.e., central unit-user plane (CU-UP)), control plane functionality (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 310 may be implemented to communicate with DU 330 for network control and signaling.

[0076] DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 340. In some aspects, DU 330 may host one or more of the following depending at least in part on a functional split such as that defined by 3GPP: a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.). In some aspects, DU 330 may further host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by DU 330 or with control functions hosted by CU 310.

[0077] The lower layer functionality may be implemented by one or more RUs 340. In some deployments, a RU 340 controlled by a DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing Fast Fourier Transform (FFT), Inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on a functional split (such as a lower layer functional split). In such an architecture, the RU 340 may be implemented to handle over-the-air (OTA) communications with one or more UEs 120. In some implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable the DU 330 and the CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0078] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, and near-RT RIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some specific implementations, the SMO framework 305 may communicate directly with one or more RUs 340 via the O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305 .

[0079] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0080] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of O1) or via the creation of RAN management policies (such as A1 policies).

[0081] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0082] Figure 4 4 is a diagram illustrating an example 400 of a time slot format according to the present disclosure. Figure 4 As shown, the time-frequency resources in the radio access network can be divided into resource blocks (shown by a single resource block (RB) 405). RB 405 is sometimes referred to as a physical resource block (PRB). RB 405 includes a set of subcarriers (e.g., 12 subcarriers) and a set of symbols (e.g., 14 symbols) that can be scheduled as a unit by a network entity (e.g., base station 110). In some aspects, RB 405 may include a set of subcarriers in a single time slot. As shown, a single time-frequency resource included in RB 405 may be referred to as a resource element (RE) 410. RE 410 may include a single subcarrier (e.g., in frequency) and a single symbol (e.g., in time). A symbol may be referred to as an orthogonal frequency division multiplexing (OFDM) symbol. RE 410 may be used to send one modulation symbol, which may be a real value or a complex value.

[0083] In some telecommunication systems (e.g., NR), RB 405 may span 12 subcarriers with a subcarrier spacing of, for example, 15 kilohertz (kHz), 30kHz, 60kHz, or 120kHz, etc., in a 0.1 millisecond (ms) duration. A radio frame may include 40 time slots and may have a length of 10ms. Thus, each time slot may have a length of 0.25ms. However, the time slot length may vary depending on the parameter set used to communicate (e.g., subcarrier spacing and / or cyclic prefix format). A time slot may be configured with a link direction (e.g., downlink or uplink) for transmission. In some aspects, the link direction for a time slot may be dynamically configured.

[0084] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0085] Figure 5 is a diagram illustrating an example 500 of uplink configuration grant (CG) communications according to the present disclosure.

[0086] In some aspects, PRBs for uplink communications may be granted dynamically, such as using a scheduling request (SR) or a buffer status report (BSR). When the UE has pending data in its buffer, the UE may first send an SR on a physical uplink control channel (PUCCH) to request radio resources in the uplink. Using periodic BSR reports, the network entity is able to know the available buffer at the UE. The network entity then sends an uplink grant downlink control information (DCI). The allocated resources are specified in the DCI for the UE to send communications on a physical uplink shared channel (PUSCH).

[0087] Alternatively, the PRBs for uplink communication may be granted according to the configuration. For example, the CG communication may include periodic uplink communication configured for the UE, so that the network entity does not need to transmit a separate DCI to schedule each uplink communication, thereby saving signaling overhead.

[0088] As shown in example 500, a UE (e.g., UE 120) may be configured with a CG configuration for CG communication. For example, the UE may receive the CG configuration via an RRC message sent by a network entity (e.g., base station 110). The CG configuration may indicate resource allocations associated with CG uplink communications (e.g., in the time domain, frequency domain, spatial domain, and / or code domain) and the periodicity with which the resource allocations are repeated, so that scheduled CG opportunities 505 for the UE occur periodically. In some examples, the CG configuration may identify a resource pool or multiple resource pools available to the UE for uplink transmission. The CG configuration may configure contention-free CG communication (e.g., where resources are dedicated to the UE for transmitting uplink communications) or contention-based CG communication (e.g., where the UE contends for access to a channel in the configured resource allocation, such as by using a channel access procedure or a channel sensing procedure).

[0089] The network entity may send a CG activation DCI to the UE to activate the CG configuration for the UE. The network entity may indicate communication parameters, such as MCS, RB allocation and / or antenna port, in the CG activation DCI for CGPUSCH communications to be sent in the scheduled CG opportunity 505. The UE may start sending in the CG opportunity 505 based at least in part on receiving the CG activation DCI. For example, starting with the next scheduled CG opportunity 505 after receiving the CG activation DCI, the UE may send PUSCH communications in the scheduled CG opportunity 505 using the communication parameters indicated in the CG activation DCI. The UE may avoid sending in the configured CG opportunity 505 before receiving the CG activation DCI.

[0090] The network entity may send a CG reactivation DCI to the UE to change the communication parameters used for CG PUSCH communications. Based at least in part on receiving the CG reactivation DCI, the UE may begin to use the communication parameters indicated in the CG reactivation DCI to transmit in scheduled CG occasions 505. For example, starting with the next scheduled CG occasion 505 after receiving the CG reactivation DCI, the UE may send PUSCH communications in scheduled CG occasions 505 based at least in part on the communication parameters indicated in the CG reactivation DCI.

[0091] In some cases, such as when the network entity needs to override scheduled CG communications for higher priority communications, the network entity may send a CG cancellation DCI to the UE to temporarily cancel or deactivate one or more subsequent CG opportunities 505 for the UE. The CG elimination DCI may deactivate only a subsequent CG opportunity 505 or subsequent N CG opportunities 505 (where N is an integer). The CG opportunities 505 after one or more (e.g., N) CG opportunities 505 after the CG elimination DCI may remain activated. Based at least in part on receiving the CG elimination DCI, the UE may avoid transmitting in one or more (e.g., N) CG opportunities 505 after receiving the CG elimination DCI. As shown in example 500, the CG elimination DCI eliminates a subsequent CG opportunity 505 for the UE. After the CG opportunity 505 (or N CG opportunities) after receiving the CG elimination DCI, the UE may automatically resume transmitting in the scheduled CG opportunity 505.

[0092] The network entity may send a CG release DCI to the UE to deactivate the CG configuration for the UE. The UE may stop transmitting in the scheduled CG occasion 505 based at least in part on receiving the CG release DCI. For example, the UE may avoid transmitting in any scheduled CG occasion 505 until another CG activation DCI is received from the base station. However, the CG elimination DCI may only deactivate a subsequent CG occasion 505 or subsequent N CG occasions 505, and the CG release DCI deactivates all subsequent CG occasions 505 for a given CG configuration of the UE until the given CG configuration is activated again by a new CG activation DCI.

[0093] With dynamic grants, the RB allocation in the uplink can be matched to the information bits of the communication and therefore use less power. However, sending the SR and waiting for the uplink grant increases latency. With CG, the RB allocation may exceed the number required for the UE information bits and may consume more power than necessary. The UE will have to fill the information bits so that all the resources allocated to the UE are used. If the UE has no information bits (no pending Packet Convergence Data Protocol PDCP packets) or has fewer information bits, the UE may still need to transmit on these allocated resources.

[0094] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0095] Figure 6 is a diagram illustrating an example 600 of skipping communications associated with authorization according to the present disclosure.

[0096] With CG scheduling, resource allocations may be larger, resource utilization may be higher, interference in the uplink may increase, and power consumption may be higher. Higher power consumption may increase the thermal performance of the UE, which may be a significant issue for extended reality (XR) devices or augmented reality (AR) devices.

[0097] In some aspects, the UE may skip or ignore communications associated with a grant (whether a dynamic grant or a CG). Otherwise, the UE sends padding bits on the allocated resources (e.g., RBs) even though the information bits may not require the allocated number of RBs to be sent. The allocated number of RBs may be over-allocated.

[0098] Example 600 shows that the UE can skip communications associated with the grant. As shown in reference numeral 605, the UE can receive a configuration (e.g., via RRC) that configures the UE to be able to skip communications associated with the grant. As shown in reference numeral 610, the UE can receive a grant for uplink communications. As shown in reference numeral 615, if data is available, the UE can send uplink communications (e.g., MAC protocol data units (PDUs)). If the grant is large, power consumption may increase. If no data is available, the UE may not send uplink communications. However, if some bits need to be sent, latency may increase because these bits may be sent in a later MAC PDU.

[0099] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0100] Figure 7 is a diagram illustrating an example 700 of resources for which authorization is skipped according to the present disclosure.

[0101] In some aspects, the UE may skip the granted resources instead of skipping the grant entirely. Example 700 illustrates the granted resources for a MAC PDU, which include skipped resources 702 (resources to be skipped) and non-skipped resources 704 (resources that will not be skipped). This flexible uplink skipping may enable the UE to select a subset of granted resources (and effectively select a subset of granted resources to be skipped) based at least in part on the size of the payload. Thus, the UE saves power by not transmitting on all granted resources. In some aspects, the UE may provide a skip indication indicating that the UE is skipping granted resources and / or using only a subset of granted resources (e.g., a non-zero appropriate subset). The skip indication may indicate skipped resources and / or non-skipped resources.

[0102] Example 700 shows a UE that can transmit on a subset of authorized resources. As shown in reference numeral 705, the UE may receive a configuration for flexible uplink skipping (e.g., via RRC signaling). As shown in reference numeral 710, the UE may receive an authorization for communication (e.g., a new uplink transmission). The authorization may include the number of allocated RBs (the total amount of RBs). As shown in reference numeral 715, if data is available, the UE may determine whether the amount of data in the buffer meets the data threshold. For example, as shown in reference numeral 720, if the number of bits in the buffer needs to be less than the total amount of RBs, the UE may transmit on a subset of the total amount of RBs. If the amount of data to be transmitted does not need to be less than the total amount of RBs, the UE may transmit data on the total amount of RBs (using all RBs). By using a subset of the total amount of RBs instead of no RBs or all RBs, the UE can reduce power consumption, save signaling resources, and reduce delays.

[0103] In some aspects, the UE may send a UCI 722 including a skip indication that notifies the network entity of the skipped resources 702 and the network entity may decode only the non-skipped resources 704 for the uplink MAC PDU. The UCI may be a flexible uplink skip (FUS) UCI ​​or UCI-FUS. The UCI-FUS may indicate which resources have been skipped, such as the number of skipped RBs or an indication of the skipped time and frequency resources (e.g., slot number, symbol number, RB number, and / or RB group number). The UCI-FUS may alternatively indicate which resources have not been skipped, and the network entity may determine the skipped resources 704 based on the indication of the non-skipped resources 702. The UCI-FUS may be sent on the PUCCH, which may be on the same slot as the PUSCH communication or on a different slot. That is, the UCI-FUS may be used to adapt the transport block (TB) size.

[0104] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The examples described are different.

[0105] Figure 8 is a diagram illustrating an example 800 of a skip indication according to the present disclosure.

[0106] Example 800 illustrates a skip indication in UCI indicating resources that are skipped as part of uplink flexible skipping or UCI-FUS. The skipped resources may be in the frequency domain and / or the time domain. The skip indication may indicate, for example, for time slot 0, symbols 10 to 13 are skipped, and PRBs greater than a specified PRB number are skipped. The skip indication may specify one or more time-frequency resource sets from a plurality of time-frequency resource sets (e.g., PRB sets, symbol sets). The plurality of time-frequency sets may be specified via RRC signaling.

[0107] In one example, if there are 14 bits available for UCI, set 0 may have 14 most significant bits (MSBs) indicating a skip indication across 14 symbols. A bit with a value of 1 may indicate that a symbol is skipped. A bit with a value of 0 may indicate that a symbol is not skipped (all RBs are used). Set 1 may have 14 MSBs indicating whether RB groups in a bandwidth part (BWP) are skipped. The BWP may be divided into 14 RB groups (RBGs), and the 14 MSBs may indicate the resources skipped on the RBGs. Set 2 may have a finer granularity (and require more bits) for time and frequency. Other set definitions that may be used include sets with bit pairs indicating both time skipping and frequency skipping. In some aspects, the skip indication may indicate the TB size used for the uplink to help quantify the amount of resources required.

[0108] As indicated above, Figure 8 are provided as examples. Other examples can be found in the Figure 8 The examples described are different.

[0109] Fig. 9 is a diagram illustrating an example 900 of skip indication according to the present disclosure. Example 900 shows REs used for PUSCH communication, DMRS, or Phase Tracking Reference Signal (PTRS).

[0110] Example 900 shows an example of skipping granted RBs but using all granted symbols. Example 900 shows that a network entity may reserve some PUSCH REs as skip indications in RBs. The skip indication in the RE may include a modulation type (e.g., MCS), zero power, or a specified reference signal. A set of REs may be reserved for the skip indication. These REs can be configured via RRC signaling. The skip indication may include a resource identifier (ID) and a skip pattern indicating the skipped or used RBs (subcarrier positions) and / or symbols (symbol positions). The RRC configuration may include a pattern type or the position of the RE. Some REs may not be used.

[0111] As indicated above, Fig. 9 are provided as examples. Other examples can be found in the Fig. 9 The examples described are different.

[0112] Fig.10 is a diagram illustrating an example 1000 of a skip indication according to the present disclosure.

[0113] Example 1000 shows an example of skipping granted RBs but using all granted symbols. Example 1000 shows that the network entity may reserve some PUSCH REs as skip indications in RBs. REs may be prepended to reduce latency. The components of PUSCH communications may be based on the number of symbols used. Skip indications may indicate RBs (negative skipping) and / or symbols (positive skipping) in each RB.

[0114] If the RB is not skipped, the network entity continues to check the reserved REs for skip indication in the time domain. If the RB is skipped, the network entity may not continue to check the REs for skip indication in the time domain. Depending on the information in the RE, the network entity may determine whether the symbol that has been skipped is used.

[0115] As indicated above, Fig.10 are provided as examples. Other examples can be found in the Fig.10 The examples described are different.

[0116] Fig.11 is a diagram illustrating an example 1100 of a skip indication according to the present disclosure.

[0117] In some aspects, in order to facilitate blind detection at the network entity, the network entity may limit the freedom of the UE to select resources to be skipped. Although the network entity may allow the UE to skip some resources in the uplink, the network entity may instruct the UE to skip the mechanism. When flexible uplink skipping is implemented, the network entity may configure the starting PRB where the UE will transmit via RRC signaling. The network entity may also perform RRC configuration for flexible uplink skipping with an RB comb pattern. Example 1100 shows an example of a comb pattern. The comb pattern may have an RB comb offset. Example 1100 shows an RB comb offset of 4 in Example 1100 (there are 3 skipped RBs before transmitting at the 4th RB offset). The comb pattern may also have an RE comb offset, which indicates where the skipped RB starts. The comb pattern may limit the number of symbols skipped.

[0118] In some aspects, when the UE transmits on a subset of RBs, the DMRS may be present in the allocated RBs. The UE may first perform coherent energy detection on the DMRS positioning. Based on the information of the time-frequency location of the detected DMRS, any strong signal detected by the network entity on the DMRS configuration resources is considered to be a valid DMRS in the used RBs. The energy detection threshold may be maintained by the network entity, and separate energy detection thresholds may be defined for single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO).

[0119] In some aspects, the power level of a resource subset may be higher than the power level of another resource set. RBs containing uplink communications may be at a higher power level than unused RBs. The network entity may maintain a power level threshold to determine that the power level of an unused resource subset is higher than the power level of a used resource subset.

[0120] As indicated above, Fig.11 are provided as examples. Other examples can be found in the Fig.11 The examples described are different.

[0121] Fig.12 are diagrams illustrating examples 1200 and 1202 of authorization opportunities according to configurations of the present disclosure.

[0122] One or more authorization configurations may be activated, and each authorization configuration may specify multiple authorization occasions (such as multiple CG occasions for CG). Alternatively, the CG occasions may belong to the same legacy semi-static configuration. In addition to CG transmissions for TBs, K retransmissions may also be configured for TBs (via RRC signaling) to improve transmission reliability. Example 1200 shows multiple CG occasions for transmission and for retransmission, which may be configured with periodicity and offsets.

[0123] Example 1202 shows that for multiple grant occasions, whether for CG, PUSCH grant or dynamic grant, there can be flexible uplink skipping. The UE can send UCI-FUS before each CG opportunity of the skipped resources. However, there may be multiple UCI-FUS that consumes signaling overhead.

[0124] As indicated above, Fig.12 Some examples are provided. Other examples can be found in the Fig.12 The examples described are different.

[0125] Fig.13 is a diagram illustrating an example 1300 of skip indication for multiple grant opportunities according to the present disclosure.

[0126] According to various aspects described herein, a UE may select resources to be skipped in each of a plurality of grant opportunities (first resources to be skipped) for communications on a physical uplink channel, and transmit a single UCI (e.g., UCI-FUS) indicating the skipped resources in the plurality of grant opportunities. The single UCI may also indicate non-skipped resources (second resources not to be skipped) such that a network entity derives the skipped resources from the non-skipped resources. That is, when indicating non-skipped resources, the single UCI may effectively indicate the skipped resources. Multiple grant opportunities may belong to a single grant configuration (e.g., a semi-static CG activated by a DCI, a grant for PUSCH transmission) or to multiple grant configurations.

[0127] Example 1300 shows a single UCI-FUS 1302 indicating a skip mode 1304 applicable to multiple grant opportunities, such as CG opportunities 1306 and CG opportunities 1308. The UCI-FUS 1302 may be sent on PUCCH resources configured by a network entity. This may enable the network entity to control the frequency of sending the UCI-FUS. If additional data arrives and the skip indication is no longer valid, the UE may send a new UCI-FUS to reconfigure the skip on the remaining CG opportunities. For example, the UE may select different skip modes 1310 indicated using a single UCI-FUS 1312 applicable to CG opportunities 1314 and CG opportunities 1316.

[0128] In some aspects, the UE may use a bitmap (e.g., bits indicating time and / or frequency resources) to indicate a skip mode (e.g., a mode on symbols and RBs). The UE may also receive an RRC configuration of the skip mode and indicate an index corresponding to the skip mode instead of a bitmap to reduce overhead. That is, the UCI-FUS may only carry an index corresponding to the skip mode in a grant occasion where the actual skip configuration is an RRC configured one.

[0129] As indicated above, Fig.13 are provided as examples. Other examples can be found in the Fig.13 The examples described are different.

[0130] Fig.14 1400 is a diagram illustrating an example of a resource for skipping authorization according to the present disclosure. Fig.14 As shown, a network entity 1410 (eg, base station 110) and a UE 1420 (eg, UE 120) may communicate with each other via a wireless network (eg, wireless network 100).

[0131] As indicated by reference numeral 1425, UE 1420 may select skipped resources to be skipped in each of a plurality of grant opportunities for communications on a physical uplink channel (e.g., PUCCH, PUSCH). As indicated by reference numeral 1430, UE 1420 may send an indication (e.g., UCI-FUS) indicating skipped resources for a plurality of grant opportunities. UE 1420 may alternatively indicate non-skipped resources so that skipped resources may be derived. As indicated by reference numeral 1435, UE 1420 may send communications in a plurality of grant opportunities using non-skipped resources instead of skipped resources.

[0132] As shown by reference numeral 1440, the network entity 1410 decodes communications in non-skipped resources instead of in skipped resources. Therefore, the network entity 1410 and the UE 1420 save processing resources, signaling resources, and power. By using a single UCI for multiple grant opportunities instead of using a UCI for each grant opportunity, the network entity 1410 and the UE 1420 save additional processing resources and signaling resources.

[0133] In some aspects, the UE 1420 may indicate a skip mode for retransmissions (such as a skip mode for K retransmissions). As shown by reference numeral 1445, the UE 1420 may send a UCI indicating skipped resources or non-skipped resources for K retransmissions in multiple grant opportunities. The UCI may be a UCI-FUS indicating the skip mode. As shown by reference numeral 1450, the UE 1420 may send retransmissions in multiple grant opportunities using non-skipped resources instead of skipped resources. The skip mode may explicitly indicate skipped resources and / or non-skipped resources.

[0134] In some aspects, the UE 1420 may send a cancellation indication that may be included in the UCI, as shown by reference numeral 1455. After the cancellation indication, the UE 1420 may not send a new UCI-FUS, and the UE 1420 may continue to use all resources in the grant opportunity without skipping resources.

[0135] As indicated above, Fig.14 are provided as examples. Other examples can be found in the Fig.14 The examples described are different.

[0136] Fig.15 are diagrams illustrating examples 1500 and 1502 of using UCI to indicate skipped resources or non-skipped resources for retransmission according to the present disclosure.

[0137] The skip mode for retransmission can be indicated by a time and frequency bitmap in the UCI-FUS. This allows maximum flexibility and allows UE 1420 to transmit on different resource sets. For example, the bitmap in the UCI-FUS for each CG opportunity of retransmission may include 14 MSBs or be indicated by 14 MSBs, which indicate a skip mode on 14 symbols. In another example, the MSB may indicate whether to skip an RB or RBG in a BWP. More bits may be used to indicate a bitmap with finer time and frequency granularity. In some aspects, the network entity 1410 may use RRC signaling to configure the skip mode, and the network entity 1410 may use an index for the skip mode instead of a bitmap to reduce the overhead of the UCI-FUS. In this way, the UCI-FUS may include an index for the skip mode instead of using more information to detail the skip mode.

[0138] Different skip modes can be indicated by a single UCI-FUS to save signaling resources while improving time and frequency diversity gain. Example 1500 shows a UCI-FUS 1504 indicating a first skip mode 1506 for the first two retransmissions and a second skip mode 1508 for the second two retransmissions. The first skip mode 1506 and the second skip mode 1508 in example 1500 use half of the resources (e.g., RBs) for the CG occasion of the MAC PDU, but hop frequencies or RBs over the total number of retransmissions. This improves frequency diversity and improves reliability while saving signaling resources. The network entity 1410 can enable and / or control the frequency hopping scheme. Time diversity can also be applied.

[0139] Example 1502 shows that a single UCI-FUS 1510 can indicate the same skip pattern 1512 not only for the initial transmission but also for any retransmission. The UE 1420 can send the UCI-FUS 1510 before the first initial transmission. In some aspects, the UCI-FUS 1510 may include an additional bit indicating that the retransmission will skip the resources of the same skip pattern 1512. For example, if the bit is set to "1", all CG opportunities in multiple CG opportunities (belonging to K retransmissions) may have similarly skipped time and frequency resources. If the bit is set to "0", the network entity 1410 may expect the UCI-FUS 1510 to include a skip pattern (e.g., a bitmap) for multiple CG opportunities or to send the UCI-FUS before each CG opportunity. The bitmap can explicitly indicate skipped resources. The bitmap can also indicate non-skipped resources so that the skipped resources can be derived from the resources of the authorized opportunity (the sum of the skipped resources and the non-skipped resources is equal to the sum of the resources of the authorized opportunity). That is, whether the bitmap explicitly indicates skipped resources or non-skipped resources, the bitmap effectively indicates skipped resources. This also applies to the indicated skip mode.

[0140] Note that while the CG occasion is used as an example of multiple grant occasions, multiple grant occasions may include grants for multiple PUSCH communications, which may be over-allocated in anticipation of incoming packets. UCI-FUS may also be used for dynamic grants for multiple grant occasions.

[0141] As indicated above, Fig.15 Some examples are provided. Other examples can be found in the Fig.15 The examples described are different.

[0142] Fig.16 1 is a diagram illustrating an example process 1600 performed, for example, by a UE in accordance with the present disclosure. Example process 1600 is an example in which a UE (eg, UE 120, UE 1420) performs operations associated with skipping resources for multiple grants.

[0143] like Fig.16 As shown, in some aspects, process 1600 may include selecting, for communications on a physical uplink channel, a first resource (skipped resource) to be skipped in each of a plurality of grant opportunities (block 1610).

For example, a network entity (e.g., using Fig.19 The communication manager 1908 and / or receiving component 1902 depicted in the figure can receive UCI indicating a first resource or a second resource of multiple authorization opportunities, skip the first resource in each authorization opportunity for communication on the physical uplink channel, and not skip the second resource, as described above.
