[0002] CROSS-REFERENCE TO RELATED APPLICATIONS
[0003] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 988,267, filed on March 11, 2020, entitled “DISABLING HYBRID AUTOMATICREPEAT REQUEST FEEDBACK,” and U.S. Non-Provisional Patent Application No. 17 / 249,675, filed on March 9, 2021, entitled “DISABLING HYBRID AUTOMATIC REPEATREQUEST FEEDBACK,” which are hereby expressly incorporated herein by reference. Technical Field
[0004] Aspects of the present disclosure generally relate to devices and methods for wireless communications, and to techniques and devices associated with disabling hybrid automatic repeat request feedback. Background Art
[0005] Wireless communication systems are widely deployed to provide various 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).
[0006] A wireless network may include several base stations (BSs) that can support communications for several user equipments (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or "forward link") refers to a communication link from a BS to a UE, while an "uplink" (or "reverse link") refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an Access Point (AP), a Radio Head, a Transmit Receiving Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.
[0007] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global level. NR (which may also be referred to as 5G) is an enhancement set 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 cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), 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 grow, further improvements to LTE, NR and other radio access technologies are still useful. Summary of the invention

[0052] As described below, a non-terrestrial network (NTN) may utilize a non-terrestrial base station to provide or assist UE access to a core network. The non-terrestrial base station may be located on a platform, which may be, for example, a satellite (e.g., a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary orbit (GEO) satellite, etc.), a balloon, an airship, an airplane, an unmanned aerial vehicle (UAV), a drone, etc. In an NTN system, due to the relatively large distance between the UE and the non-terrestrial base station and / or the relatively large distance between the terrestrial base station and the non-terrestrial base station, the propagation delay may be significant. In some cases, due to the significant propagation delay in the NTN system, disabling HARQ feedback to avoid a pause in the HARQ process may be desirable. Thus, some HARQ processes may need to be configured to disable HARQ feedback. In one or more examples, such configuration may be performed by a higher layer (e.g., a radio link control (RLC) layer, also referred to as an L3 layer), while the HARQ feedback is sent by a lower layer (e.g., a physical (PHY) layer, also referred to as an L1 layer).
[0053] Some aspects described herein provide techniques and devices for disabling HARQ feedback. For example, the techniques and devices described herein enable configuration and use of a HARQ process (e.g., a downlink HARQ process or an uplink HARQ process) with HARQ feedback disabled at the physical layer. In some aspects, the techniques and devices described herein may be used to disable HARQ feedback to reduce the likelihood of stalling a HARQ process in, for example, an NTN network or another scenario where a HARQ process stall may occur.
[0054] In the case of a downlink HARQ process, the base station may identify the HARQ process to be used for the downlink communication based at least in part on whether HARQ feedback is to be provided for the downlink communication. In one or more examples, when HARQ feedback is to be provided, the base station may identify the HARQ process for which HARQ feedback is enabled. Conversely, when HARQ feedback will not be provided, the base station may identify the HARQ process for which HARQ feedback is disabled. The base station may then transmit a downlink communication, which includes a HARQ process identifier indicating the HARQ process to be used for the downlink communication. The base station may selectively monitor to find HARQ feedback associated with the downlink communication based at least in part on whether HARQ feedback is to be provided for the downlink communication. The UE may receive the downlink communication and may selectively provide HARQ feedback for the downlink communication based at least in part on the HARQ identifier and information (e.g., configuration, dynamic indication, etc.) indicating whether HARQ feedback is enabled or disabled for the HARQ process.
[0055] In the case of an uplink HARQ process, the UE may transmit to the base station an indication of whether HARQ feedback is to be provided for uplink communication. The base station may receive the indication and identify the HARQ process to be used for the uplink communication based at least in part on the indication. In one or more examples, when HARQ feedback is to be provided, the base station may identify the HARQ process for which HARQ feedback is enabled. Conversely, when HARQ feedback is not provided, the base station may identify the HARQ process for which HARQ feedback is disabled. The base station may then transmit a grant associated with the uplink communication, the grant including a HARQ process identifier indicating the HARQ process to be used for the uplink communication. The UE may receive the grant, transmit uplink communication according to the grant, and selectively monitor for retransmission grants based at least in part on the HARQ process identifier and information indicating whether HARQ feedback is disabled for the HARQ process.
[0056] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings of this article, those skilled in the art will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is independently implemented or implemented in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can 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 practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.
[0057] 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 such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.
[0058] It should be noted that while various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs after 5G (e.g., 6G).
[0059] 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 (NR) network and / or an LTE network, etc. or may include elements thereof. The wireless network 100 may include several base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, a B node, a gNB, a 5G B node (NB), an access point, a transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.
[0060] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. The BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" may be used interchangeably herein.
[0061] In some aspects, the cell may not necessarily be stationary, and the geographic area of the cell may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.
[0062] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , a relay BS 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.
[0063] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).
[0064] In some examples, such as Figure 1 As indicated in , the cellular cells may be provided by the base stations 110 of the NTN. Such base stations 110 may also be referred to as non-terrestrial base stations 110 or non-terrestrial access points. As used herein, "NTN" may refer to a network for which access is provided or assisted by non-terrestrial base stations 110. In some NTN deployments, the non-terrestrial base stations 110 may be located on an airborne platform or an orbital platform. Examples of such platforms include satellites (e.g., LEO satellites, MEO satellites, GEO satellites, etc.), balloons, airships, airplanes, UAVs, drones, etc.
[0065] In some NTN deployments (e.g., sometimes referred to as transparent architecture or bent pipe architecture), non-ground base station 110 may act as a relay station to relay communications between UE 120 and ground base station 110 (e.g., base station 110 located on the ground or on a tower). In this case, non-ground base station 110 may perform, for example, frequency conversion and / or radio frequency amplification on the communications relayed between UE 120 and ground base station 110. For example, UE 120 may transmit uplink communications to non-ground base station 110, which may relay the uplink communications (e.g., after performing frequency conversion, radio frequency amplification, etc.) to ground base station 110. Ground base station 110 may perform additional processing on the uplink communications and / or may transmit the uplink communications to the core network. As another example, ground base station 110 may transmit downlink communications to non-ground base station 110, which may relay the downlink communications (e.g., after performing frequency conversion, radio frequency amplification, etc.) to UE 120. In some aspects, UE 120 and / or ground base station 110 may be referred to as a ground station (GS).
[0066] A network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.
[0067] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE 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, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.
[0068] Some UEs may be considered as machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to or to a network (e.g., a wide area network (such as the Internet) or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as client equipment (CPE). 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 aspects, a processor component and a 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 operationally coupled, communicatively coupled, electronically coupled, and / or electrically coupled.
[0069] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific RAT and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as 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.
[0070] like Figure 1As shown in , UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive a downlink communication including a HARQ process identifier indicating a HARQ process to be used for the downlink communication; and may selectively provide HARQ feedback for the downlink communication based at least in part on the HARQ identifier and information indicating whether HARQ feedback is disabled for the HARQ process. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.
[0071] Similarly, the base station 110 may include a communication manager 150. As described in greater detail elsewhere herein, the communication manager 150 may determine whether to provide HARQ feedback for a downlink communication; may identify a HARQ process to be used for the downlink communication based at least in part on whether HARQ feedback is to be provided for the downlink communication; and may transmit the downlink communication including a HARQ process identifier indicating the HARQ process to be used for the downlink communication. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0072] like Figure 1 As shown in , UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may transmit an indication of whether HARQ feedback is to be provided for an uplink communication; receive a grant associated with the uplink communication, the grant including a HARQ process identifier indicating a HARQ process to be used for the uplink communication; and may selectively monitor for a retransmission grant associated with the uplink communication based at least in part on the HARQ process identifier and information indicating whether HARQ feedback is disabled for the HARQ process. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.
[0073] Similarly, the base station 110 may include a communication manager 150. As described in greater detail elsewhere herein, the communication manager 150 may receive an indication of whether to provide HARQ feedback for an uplink communication; may identify a HARQ process to be used for the uplink communication based at least in part on the indication; and may transmit a grant associated with the uplink communication, the grant including a HARQ process identifier indicating the HARQ process to be used for the uplink communication. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.
[0074] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 Examples described.
[0075] Figure 2 is a diagram illustrating an example 200 of a base station 110 and a UE 120 in communication in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.
[0076] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.
[0077] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a channel quality indicator (CQI) parameter, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284.
[0078] 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 base station 110 via the communication unit 294.
[0079] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, etc. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements coupled to one or more transmission and / or reception components (such as Figure 2 One or more antenna elements of one or more components).
[0080] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, where applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as described with reference to Figures 3A-3G and 4-7).
[0081] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modulator and / or demodulator 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 aspects of any of the methods described herein (e.g., as described with reference to Figures 3A-3G and 4-7).
[0082] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) of the base station 110 may perform one or more techniques associated with disabling HARQ feedback, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 4 The process of 400 Figure 5 The process of 500 Figure 6 The process of 600 Figure 7 The operations of process 700, and / or other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. Scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.
[0083] In some aspects, the UE 120 may include: a device for receiving information indicating whether HARQ feedback is disabled for a HARQ process; a device for receiving a downlink communication, the downlink communication including a HARQ process identifier for the HARQ process, the HARQ process identifier indicating that the HARQ process is to be used for the downlink communication; a device for selectively providing HARQ feedback for the downlink communication based at least in part on the information indicating whether HARQ feedback is disabled for the HARQ process, and so on. Additionally or alternatively, the UE 120 may include a device for performing one or more other operations described herein. In some aspects, such a device may include a communication manager 140. Additionally or alternatively, such a device may include a communication manager 140 in conjunction with Figure 2 One or more components of UE 120 are described.
[0084] In some aspects, the base station 110 may include: means for transmitting information indicating whether HARQ feedback is disabled for a HARQ process; means for transmitting a downlink communication, the downlink communication including a HARQ process identifier for the HARQ process, the HARQ process identifier indicating the HARQ process to be used for the downlink communication, etc. Additionally or alternatively, the base station 110 may include means for performing one or more other operations described herein. In some aspects, such means may include the communication manager 150. In some aspects, such means may include in conjunction with Figure 2 One or more components of base station 110 are described.
[0085] In some aspects, the UE 120 may include: means for transmitting an indication of whether to provide HARQ feedback or HARQ retransmission for an uplink communication; means for receiving a grant for transmitting the uplink communication, the grant including a HARQ process identifier indicating a HARQ process to be used for the uplink communication; means for selectively monitoring for a retransmission grant associated with the uplink communication based at least in part on the HARQ process identifier and information indicating whether HARQ feedback or HARQ retransmission is disabled for the HARQ process, and the like. Additionally or alternatively, the UE 120 may include means for performing one or more other operations described herein. In some aspects, such means may include the communications manager 140. Additionally or alternatively, such means may include a communication manager 140 in conjunction with the communication manager 140. Figure 2 One or more components of UE 120 are described.
[0086] In some aspects, the base station 110 may include: means for transmitting an indication of whether to provide HARQ feedback or HARQ retransmission for an uplink communication; means for identifying a HARQ process to be used for the uplink communication based at least in part on the indication; means for transmitting a grant for transmitting the uplink communication, the grant including a HARQ process identifier indicating the HARQ process to be used for the uplink communication, and the like. Additionally or alternatively, the base station 110 may include means for performing one or more other operations described herein. In some aspects, such means may include the communications manager 150. In some aspects, such means may include in conjunction with Figure 2 One or more components of base station 110 are described.
[0087] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.
[0088] As described above, NTN can utilize non-terrestrial base stations to provide or assist UE access to the core network. The non-terrestrial base station can be located on a platform, which can be, for example, a satellite (e.g., LEO satellite, MEO satellite, GEO satellite, etc.), a balloon, an airship, an airplane, a UAV, a drone, etc. In the NTN system, due to the relatively large distance between the UE and the non-terrestrial base station and / or the relatively large distance between the terrestrial base station and the non-terrestrial base station, the propagation delay may be significant. In some cases, due to the significant propagation delay in the NTN system, disabling HARQ feedback to avoid the pause of the HARQ process may be desirable. In this way, some HARQ processes may need to be configured to disable HARQ feedback. In general, such configuration needs to be performed by a higher layer (e.g., an RLC layer, also referred to as an L3 layer), and the HARQ feedback is sent by a lower layer (e.g., a PHY layer, also referred to as an L1 layer).
[0089] Some aspects described herein provide techniques and devices for disabling HARQ feedback. For example, the techniques and devices described herein enable configuration and use of a HARQ process (e.g., a downlink HARQ process or an uplink HARQ process) with HARQ feedback disabled at the physical layer. In some aspects, the techniques and devices described herein may be used to disable HARQ feedback. Disabling HARQ feedback prevents stalling of the HARQ process. For example, as described herein, propagation delays may cause stalling of the HARQ process, which may reduce the quality of service of the UE (e.g., due to a high probability of HARQ process errors), cause waste of network resources, and reduce network performance and efficiency. Therefore, by enabling disabling HARQ feedback, the techniques and devices described herein reduce the possibility of stalling HARQ, thereby improving the quality of service of the UE (e.g., by reducing the possibility of HARQ process errors), reducing waste of network resources, and improving network performance and efficiency. It is worth noting that the techniques and devices described herein may be used in, for example, an NTN network or another scenario where a stall of the HARQ process may occur.
[0090] Figures 3A-3G is a diagram illustrating various examples associated with disabling HARQ feedback according to the present disclosure.
[0091] Figure 3A3 is a diagram illustrating an example 300 associated with disabling HARQ feedback associated with downlink communications to be transmitted by a base station (e.g., base station 110) for reception by a UE (e.g., UE 120). The base station may be a non-terrestrial base station (e.g., non-terrestrial base station 110) or may be a terrestrial base station (e.g., terrestrial base station 110 that does not utilize the non-terrestrial base station as a relay). In some cases, when the base station is a terrestrial base station (e.g., terrestrial base station 110), the non-terrestrial base station (e.g., non-terrestrial base station 110) acts as a relay, such as Figure 3A As indicated.
[0092] like Figure 3A As indicated by reference numeral 302, the base station may provide, and the UE may receive, information indicating one or more HARQ processes in a set of HARQ processes configured on the UE for which HARQ feedback is to be disabled.
[0093] For example, a base station may transmit (e.g., via radio resource control (RRC) signaling) a configuration indicating that HARQ feedback will be disabled for one or more HARQ processes. In some aspects, the configuration includes a value indicating the number of HARQ processes for which HARQ feedback is disabled. For example, when Y (Y ≥ 1, such as 16) HARQ processes are configured, the value may indicate that HARQ feedback is disabled for X (X ≤ Y) of the Y HARQ processes. In some aspects, the X HARQ processes for which HARQ feedback is disabled may be determined as HARQ process 0 to HARQ process (X-1) or as HARQ process (YX) to HARQ process (Y-1). In this way, the configuration may indicate a range of HARQ processes for which HARQ feedback is disabled. Alternatively, in some aspects, the configuration includes a bitmap that indicates whether HARQ feedback is disabled for each HARQ process in the set of HARQ processes (e.g., where bit 1 indicates that HARQ feedback is enabled for the corresponding HARQ process, and bit 0 indicates that HARQ feedback is disabled for the corresponding HARQ process). In some aspects, the configuration indicates that HARQ feedback is disabled for retransmissions of one or more of the one or more HARQ processes (e.g., HARQ feedback is disabled for retransmissions, but HARQ feedback is not disabled for initial transmissions). Additionally or alternatively, the configuration may indicate that HARQ feedback is disabled for initial transmissions of one or more of the one or more HARQ processes (e.g., HARQ feedback is disabled for initial transmissions, but HARQ feedback is not disabled for retransmissions).
[0094] As another example, the base station may transmit a dynamic indication including information indicating whether HARQ feedback is disabled for a HARQ process associated with the downlink communication. In some aspects, the dynamic indication may be transmitted via, for example, a physical downlink control channel (PDCCH), a media access control element (MAC-CE), or the like. Thus, in some aspects, the base station may dynamically switch (e.g., bit 0 = not switched, bit 1 = switched) HARQ feedback for a given HARQ process via, for example, a PDCCH or a MAC-CE. In some aspects, the dynamic indication may further indicate that HARQ feedback is disabled for retransmissions of the HARQ process (e.g., HARQ feedback is disabled for retransmissions, but HARQ feedback is not disabled for initial transmissions). Additionally or alternatively, the configuration may indicate that HARQ feedback is disabled for initial transmissions of the HARQ process (e.g., HARQ feedback is disabled for initial transmissions, but HARQ feedback is not disabled for retransmissions). In some aspects, the dynamic indication may override a configuration indicating whether HARQ feedback is disabled for the HARQ process (e.g., a configuration previously provided to the UE by the base station).
[0095] As indicated by reference numeral 304, the base station may determine whether to provide HARQ feedback for a downlink communication to be transmitted to the UE. In some aspects, the base station determines whether to provide HARQ feedback for the downlink communication based at least in part on one or more mapping rules for a logical channel associated with the downlink communication. The mapping rule for the logical channel may be associated with, for example, a quality of service (QoS) flow. For example, the mapping rule may indicate that HARQ feedback will be provided for the QoS flow, or may indicate that HARQ feedback will not be provided for the QoS flow. As another example, the mapping rule for the logical channel may be associated with a logical channel configuration (e.g., a configuration indicating whether the logical channel is allowed to use a specific subcarrier spacing (SCS), a specific parameter set, etc.). Here, the mapping rule may indicate that HARQ feedback will be provided, for example, when the logical channel is allowed to use a specific SCS and a specific parameter set, or may indicate that HARQ feedback will not be provided, for example, when the logical channel is not allowed to use a specific SCS and a specific parameter set. As another example, the mapping rule for the logical channel may be associated with the amount of pending data of the logical channel. For example, when the amount of data required to be transmitted for the logical channel meets a threshold, the mapping rule may indicate that HARQ feedback will not be provided. In some aspects, the base station may be configured with one or more of the one or more mapping rules. Additionally or alternatively, the base station may receive one or more of the one or more mapping rules from the UE.
[0096] In some aspects, the base station determines whether to provide HARQ feedback for the downlink communication based at least in part on UE capability information associated with disabling HARQ feedback. For example, the capability information may include an indication of whether the UE supports disabling HARQ feedback for any HARQ process in the HARQ process set. As another example, the capability information may include an indication of a specific number of HARQ processes for which the UE supports disabling HARQ feedback. As another example, the capability information may include an indication of whether the UE supports disabling HARQ feedback for the HARQ process (e.g., the HARQ process associated with the downlink communication). In some aspects, the UE may provide and the base station may receive capability information associated with the UE. In some aspects, the capability information may include a bitmap indicating whether each HARQ process in the HARQ process set supports disabling HARQ feedback.
[0097] In some aspects, the capability information may include a preference for disabling HARQ feedback. That is, in some aspects, the UE may indicate a preference for dynamically disabling HARQ feedback associated with a HARQ process (e.g., when the UE is in connected mode). In some aspects, the UE may provide the preference via, for example, an RRC message, a MAC-CE, etc. and the base station may receive the preference via, for example, an RRC message, a MAC-CE, etc.
[0098] As indicated by reference numeral 306, the base station may identify a HARQ process to be used for the downlink communication based at least in part on whether HARQ feedback is to be provided for the downlink communication. For example, the base station may determine that HARQ feedback is to be provided for the downlink communication, and may identify an available HARQ process with HARQ feedback enabled as the HARQ process to be used for the downlink communication. As another example, the base station may determine that HARQ feedback will not be provided for the downlink communication, and may identify an available HARQ process with HARQ feedback disabled as the HARQ process to be used for the downlink communication. As another example, the base station may determine that HARQ feedback will not be provided for the downlink communication, and may determine that a HARQ process without HARQ feedback disabled is available. In this example, the base station may identify an available HARQ process with HARQ feedback enabled as the HARQ process to be used for the downlink communication, and may provide a dynamic indication to the UE so that HARQ feedback is disabled for the HARQ process.
[0099] In some aspects, a base station may determine whether to provide HARQ feedback for a given HARQ process. In some aspects, a base station may determine whether HARQ feedback should be provided for a given HARQ process based at least in part on HARQ feedback received (e.g., from a UE) in a MAC-CE or uplink RRC message. In some aspects, a base station may transmit a configuration indicating a change regarding whether HARQ feedback should be provided for a given HARQ process or a change regarding a mapping rule for a logical channel based at least in part on determining whether HARQ feedback should be provided for a given HARQ process.
[0100] As a general example (applicable to both downlink and uplink communications), when data for communication arrives at a logical channel, an indication of whether HARQ feedback is required for the communication is indicated by a higher layer (e.g., an RLC layer) to a lower layer (e.g., a MAC layer). Here, the MAC entity may form a MAC protocol data unit (PDU) and provide the MAC PDU to the physical layer. In some aspects, the MAC entity may prioritize data from logical channels that require HARQ feedback over data from logical channels that do not require HARQ feedback. In some aspects, the MAC PDU includes data from one or more logical channels that require HARQ feedback, or includes data from one or more logical channels that do not require HARQ feedback. Here, an indication of whether HARQ feedback is required is provided to the physical layer (together with the MAC PDU). As described herein, a higher layer may generate an indication (i.e., may determine whether to provide HARQ feedback for communication) based at least in part on a QoS flow of a logical channel, a logical channel configuration of a logical channel, an amount of pending data for a logical channel, and the like. Based on the indication, the physical layer may then identify an available HARQ process to be used for communication (e.g., a HARQ process for which HARQ feedback is enabled or a HARQ process for which HARQ feedback is disabled, depending on the indication). In some aspects, if at least one MAC service data unit (SDU) requires HARQ feedback in a given MAC PDU, a HARQ process with HARQ feedback enabled is identified for communication. Notably, in some aspects, if a HARQ process that satisfies the indication is not available, the physical layer may override the configuration of the HARQ process. For example, the indication may indicate that HARQ feedback is to be provided for downlink communication, but the physical layer may determine that there is no available HARQ process with HARQ feedback enabled. Here, the physical layer may select a HARQ process with HARQ feedback disabled and provide a dynamic indication to the UE indicating that HARQ feedback is enabled for the selected HARQ process (e.g., as described above).
[0101] As indicated by reference numeral 308, the base station may transmit a downlink communication. Here, the downlink communication may include a HARQ process identifier indicating the HARQ process to be used for the downlink communication. That is, the downlink communication may include a HARQ process identifier that identifies the HARQ process identified by the base station as the HARQ process to be used for the downlink communication. As shown, the UE may receive the downlink communication, which includes a HARQ process identifier indicating the HARQ process to be used for the downlink communication.
[0102] As indicated by reference numeral 310, the UE may determine whether HARQ feedback is disabled for a HARQ process identified in a downlink communication, and as indicated by reference numeral 312, may selectively provide HARQ feedback associated with the downlink based at least in part on the determination. Thus, the UE may determine whether HARQ feedback is enabled for a HARQ process identified in a downlink, and selectively provide HARQ feedback for the downlink communication based at least in part on a HARQ identifier and information indicating whether HARQ feedback is disabled for the identified HARQ process. For example, the UE may receive (e.g., in a configuration, in a dynamic indication, etc., as described above) information indicating whether HARQ feedback is disabled for the HARQ process, as described above. Here, when receiving a downlink communication including a HARQ process identifier associated with the HARQ process, the UE may identify the HARQ process as the HARQ process to be used for the downlink communication. The UE can therefore determine whether HARQ feedback is disabled for the HARQ process, and can selectively provide HARQ feedback accordingly (e.g., when HARQ feedback is not disabled for the HARQ process, the UE can provide HARQ feedback, and when HARQ feedback is disabled for the identified HARQ process, the UE may not provide HARQ feedback).
[0103] As indicated by reference numeral 314, the base station can selectively monitor for HARQ feedback associated with the downlink communication based at least in part on whether HARQ feedback is to be provided for the downlink communication.
[0104] Figure 3B 3 is a diagram illustrating an example 350 associated with disabling HARQ feedback associated with uplink communications to be transmitted by a UE (e.g., UE 120) for reception by a base station (e.g., base station 110). The base station may be a non-terrestrial base station (e.g., non-terrestrial base station 110) or may be a terrestrial base station (e.g., terrestrial base station 110 that does not utilize the non-terrestrial base station as a relay). In some cases, when the base station is a terrestrial base station (e.g., terrestrial base station 110), the non-terrestrial base station (e.g., non-terrestrial base station 110) acts as a relay, such as Figure 3BAs indicated.
[0105] like Figure 3B As indicated by reference numeral 352 in the figure, the base station may provide and the UE may receive information indicating that HARQ feedback is disabled for one or more HARQ processes in the set of HARQ processes configured on the UE. For example, the base station may transmit a configuration indicating that HARQ feedback is to be disabled for one or more HARQ processes, or may transmit a dynamic indication including information indicating whether HARQ feedback is disabled for a given HARQ process, as described above in conjunction with Figure 3A As described.
[0106] As indicated by reference numeral 354, the UE may determine whether to provide HARQ feedback for uplink communications to be transmitted by the UE.
[0107] In some aspects, the UE determines whether to provide HARQ feedback for the uplink communication based at least in part on one or more mapping rules for a logical channel associated with the uplink communication. For example, the mapping rule for the logical channel may be associated with: a quality QoS flow associated with the logical channel; a logical channel configuration associated with the logical channel; or a pending amount of data for the logical channel, etc., as described above. In some aspects, the UE may be configured with one or more of the one or more mapping rules. Additionally or alternatively, the UE may receive one or more of the one or more mapping rules (e.g., from a base station).
[0108] In some aspects, the UE determines whether to provide HARQ feedback for the uplink communication based at least in part on UE capability information associated with disabling HARQ feedback. For example, the capability information may include an indication of whether the UE supports disabling HARQ feedback for any HARQ process in a set of HARQ processes, a specific number of HARQ processes for which the UE supports disabling HARQ feedback, whether the UE supports disabling HARQ feedback for a given HARQ process, and the like, as described above. In some aspects, the UE may provide and the base station may receive capability information associated with the UE. In some aspects, the capability information may include a bitmap indicating whether disabling HARQ feedback is supported for each HARQ process in the set of HARQ processes. In some aspects, the capability information may include a preference for disabling HARQ feedback, as described above.
[0109] As indicated by reference numeral 356, the UE may transmit, and the base station may receive, an indication of whether to provide HARQ feedback for an uplink communication. In some aspects, the indication may include an indication of whether the UE will monitor for a retransmission uplink grant associated with the uplink communication. In some aspects, the UE may transmit the indication in a scheduling request associated with the uplink communication. In some aspects, the UE may transmit a scheduling request including the indication via, for example, uplink control information (UCI), a physical uplink control channel (PUCCH), a MAC-CE, a new physical SR configuration resource, a specific scheduling request opportunity, etc. Alternatively, in some aspects, the UE may transmit the indication in a buffer status report (BSR). Here, the BSR may include a logical channel identifier of a logical channel associated with the uplink communication. In some aspects, when the indication is transmitted via a MAC-CE, the MAC-CE may include a bitmap indicating, for each logical channel in a set of logical channels, whether monitoring is to be performed to find a retransmission grant. In some aspects, the MAC-CE is a fixed-size MAC-CE with zero length, where the indication may be transmitted using reserved bits in a subheader.
[0110] As indicated by reference numeral 358, the base station may identify a HARQ process to be used for the uplink communication based at least in part on an indication of whether HARQ feedback is to be provided for the uplink communication (i.e., an indication of whether the UE will monitor for a retransmission uplink grant associated with the uplink communication). For example, when the indication indicates that HARQ feedback is to be provided for the uplink communication, the base station may identify an available HARQ process with HARQ feedback enabled as the HARQ process to be used for the uplink communication. As another example, when the indication indicates that HARQ feedback is not to be provided for the uplink communication, the base station may identify an available HARQ process with HARQ feedback disabled as the HARQ process to be used for the uplink communication. As another example, when the indication indicates that HARQ feedback is not to be provided for the uplink communication, the base station may determine that a HARQ process without HARQ feedback disabled is available. In this example, the base station may identify an available HARQ process with HARQ feedback enabled as a HARQ process to be used for uplink communication, and may provide a dynamic indication to the UE so that HARQ feedback is disabled for the HARQ process.
[0111] As indicated by reference numeral 360, the base station may transmit and the UE may receive a grant associated with the uplink communication. Here, the grant may include a HARQ process identifier indicating the HARQ process to be used for the uplink communication. That is, the grant may include a HARQ process identifier that identifies the HARQ process identified by the base station as the HARQ process to be used for the uplink communication.
[0112] As indicated by reference numeral 362, the UE may transmit the uplink communication based at least in part on the grant, and the base station may receive the uplink communication transmitted by the UE.
[0113] As indicated by reference numeral 364, the UE may determine whether HARQ feedback is disabled for the HARQ process identified in the grant, and as indicated by reference numeral 366, may selectively monitor for a retransmission grant associated with the uplink communication based at least in part on the determination. Here, the UE may determine whether HARQ feedback is enabled for the identified HARQ process, and selectively monitor for a retransmission grant of the uplink communication based at least in part on the HARQ process identifier and information indicating whether HARQ feedback is disabled for the identified HARQ process. For example, the UE may receive (e.g., in a configuration, in a dynamic indication, etc.) information indicating whether HARQ feedback is disabled for the HARQ process, as described above. Here, when a grant including a HARQ process identifier associated with the HARQ process is received, the UE may identify the HARQ process as the HARQ process to be used for the uplink communication. The UE may therefore determine whether HARQ feedback is disabled for the HARQ process. Here, the UE may transmit the uplink communication based on the grant, and may accordingly selectively monitor for a retransmission grant of the uplink communication (e.g., when HARQ feedback is not disabled for the HARQ process, the UE may monitor for a retransmission grant, and when HARQ feedback is disabled for the identified HARQ process, the UE may not monitor for a retransmission grant).
[0114] As indicated by reference numeral 368, the base station may selectively provide a retransmission grant associated with the uplink communication based at least in part on whether HARQ feedback is disabled for the HARQ process. For example, when HARQ feedback is enabled for the HARQ process, the base station may provide retransmissions associated with the uplink communication as needed. Conversely, when HARQ feedback is disabled for the HARQ process, the base station may refrain from providing retransmissions associated with the uplink communication.
[0115] Figure 3C is a diagram illustrating an example of identifying HARQ processes for different logical channels, as described herein. Figure 3C The described operations may be performed by a wireless communication device such as a base station (e.g., base station 110), a UE (e.g., UE 120), etc. Figure 3C In the embodiment of the present invention, the wireless communication device may determine that HARQ feedback is not required for communication for the first logical channel (LCH1). The wireless communication device may, for example, determine that HARQ feedback is not required for communication for the first logical channel (LCH1) based at least in part on the indication of a QoS flow associated with the first logical channel (in Figure 3CIn this example, the wireless communication device may identify HARQ processes HPN-1 and HPN as HARQ processes to be used for the first logical channel.
[0116] As further shown, the wireless communication device may determine that HARQ feedback is required for communication of the second logical channel (LCH2). The wireless communication device may make this determination, for example, based at least in part on a logical channel configuration associated with the second logical channel (e.g., based at least in part on a mapping rule indicating that HARQ feedback is required). In this example, the wireless communication device may identify the HARQ process HP1 as the HARQ process to be used for the second logical channel.
[0117] As further shown, the wireless communication device may determine that HARQ feedback is required for communication of a third logical channel (LCHi). The wireless communication device may, for example, determine that HARQ feedback is required for communication of a third logical channel (LCHi) based at least in part on an indication of a QoS flow associated with the third logical channel (in Figure 3C The wireless communication device may identify HARQ processes HP2 and HP3 as HARQ processes to be used for the third logical channel.

As indicated by reference numeral 354, the UE determines (e.g., based on executing Figure 3CAs shown in the figure, the UE transmits an indication that HARQ feedback is to be provided for uplink communication to be transmitted to the base station. As shown by reference numeral 356, the UE transmits an indication that HARQ feedback is to be provided for uplink communication. As shown by reference numeral 358, the base station receives the indication and identifies HARQ process HP2 (e.g., HARQ process HP2 is a HARQ process for which HARQ feedback is not disabled) as the HARQ process to be used for the uplink communication. As shown by reference numeral 360, the base station transmits and the UE receives an uplink grant, and the uplink grant includes a HARQ process identifier of the HARQ process HP2.
