Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to pending U.S. non-provisional application No. 17 / 738,933, filed on May 6, 2022, which is assigned to the assignee of the present application and is hereby expressly incorporated herein by reference as if fully set forth below and for all applicable purposes. Technical Field

[0003] The techniques discussed below relate generally to user equipment procedures for buffer status reporting, and more particularly, to user equipment enhanced procedures for buffer status reporting to optimize network uplink component carrier activation and improve network performance. Background Art

[0004] A user equipment (UE) may buffer data waiting for uplink transmission until resources for uplink transmission of the data are scheduled. Thus, data may accumulate in one or more buffers while waiting to generate a packet data unit (PDU) configured to transmit accumulated data in the uplink direction. The buffered data may be grouped according to logical channels. One or more logical channel groups (LCGs) may be established. The UE may be triggered from time to time to send a buffer status report (BSR) to the network. The content of the BSR informs the network of the amount of data waiting for uplink transmission stored in the UE's buffer (or multiple buffers). The network may allocate resources, such as one or more component carriers, to the UE based in part on the amount of data waiting for uplink transmission stored in the UE's buffer (or multiple buffers).

[0017] The specific embodiments described below in conjunction with the accompanying drawings are intended as descriptions of various configurations and are not intended to represent the only configurations in which the concepts described herein can be practiced. In order to provide a thorough understanding of the various concepts, the specific embodiments include specific details. However, it is apparent to those skilled in the art that these concepts can be practiced without these specific details. In some examples, well-known structures and components are shown in block diagram form to avoid obscuring these concepts.

[0018] Although various aspects and examples are described in this application by illustrating some examples, it will be understood by those skilled in the art that additional specific implementations and use cases can be generated in many different arrangements and scenarios. The innovation described herein can be implemented across many different platform types, devices, systems, shapes, sizes, and packaging arrangements. For example, various aspects and / or use can be generated via integrated chip examples and other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / shopping equipment, medical equipment, AI-enabled devices, etc.). Although some examples may or may not specifically relate to use cases or applications, the innovation described may have various types of applicability. Specific implementations can range from chip-level or modular components to non-modular, non-chip-level specific implementations, and further to the range of aggregated, distributed, or original equipment manufacturer (OEM) devices or systems in conjunction with one or more aspects of the described innovation. In some practical settings, the device in conjunction with the described aspects and features may also necessarily include additional components and features for the specific implementation and practice of the examples claimed and described. For example, the transmission and reception of wireless signals necessarily include multiple components for analog and digital purposes (e.g., hardware components, including antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processors, interleavers, adders / summers, etc.). The innovations described herein are intended to be practiced in a wide variety of devices of different sizes, shapes, and configurations, chip-level components, systems, distributed arrangements, disaggregated arrangements (e.g., base stations and / or user equipment (UE)), end-user devices, etc.

[0019] Described herein are methods and apparatus for a process for determining whether to transmit a short buffer status report (BSR) or a long BSR from a wireless communication device based on an evaluation of at least one parameter, which at least one parameter may be associated with, for example, a peak power envelope of the wireless communication device, a data transmission rate historically achieved by the wireless communication device, a number of component carriers available for buffers scheduled for full upload of stored data, a cost function, an amount of data associated with a logical channel group awaiting uplink transmission, a type of wireless communication device, or a communication latency of the wireless communication device.

[0020] The various concepts presented throughout this disclosure may be implemented across a wide variety of telecommunication systems, network architectures, and communication standards. Figure 1 , various aspects of the present disclosure are illustrated with reference to a wireless communication system 100 as an illustrative example and not as a limitation. The wireless communication system 100 includes three interacting domains: a core network 102, a radio access network (RAN) 104, and a user equipment (UE) 106. By means of the wireless communication system 100, the UE 106 may be enabled to perform data communications with an external data network 110, such as (but not limited to) the Internet.

[0021] The RAN 104 may implement any suitable one or more wireless communication technologies to provide radio access to the UE 106. As an example, the RAN 104 may operate according to the 3rd Generation Partnership Project (3GPP) New Radio (NR) specification, commonly referred to as 5G. As another example, the RAN 104 may operate according to a hybrid of 5G NR and Evolved Universal Terrestrial Radio Access Network (eUTRAN) standards, commonly referred to as Long Term Evolution (LTE). 3GPP refers to such a hybrid RAN as the Next Generation RAN or NG-RAN. Of course, many other examples may be utilized within the scope of the present disclosure.

[0022] As illustrated, RAN 104 includes multiple base stations 108. In a broad sense, a base station is a network element in a radio access network that is responsible for radio transmission and reception to or from a UE in one or more cells. In different technologies, standards or contexts, a base station may be referred to as a base transceiver station (BTS), a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS), an extended service set (ESS), an access point (AP), a node B (NB), an eNode B (eNB), a gNode B (gNB), a transmission reception point (TRP) or some other suitable terminology by those skilled in the art. In some examples, a base station may include two or more TRPs that may be co-located or non-co-located. Each TRP may communicate on the same or different carrier frequencies in the same or different frequency bands. In an example in which RAN 104 operates according to two standards, LTE and 5G NR, one of the base stations may be an LTE base station, and the other base station may be a 5G NR base station.

[0023] The RAN 104 is further illustrated as supporting wireless communications for a plurality of mobile devices. In the 3GPP standards, a mobile device may be referred to as a user equipment (UE), but those skilled in the art may also refer to it as a mobile station (MS), a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal (AT), a mobile terminal, a wireless terminal, a remote terminal, a handset, a terminal, a user agent, a mobile client, a client, or some other suitable term. A UE may be a device (e.g., a mobile device) that provides a user with access to network services.

[0024] Within the present disclosure, a "mobile" device does not necessarily need to have the ability to move, and may be stationary. The term mobile device or mobile device broadly refers to a wide variety of devices and technologies. A UE may include a plurality of hardware structural components whose size, shape, and arrangement facilitate communication; such components may include antennas, antenna arrays, RF chains, amplifiers, one or more processors, etc. electrically coupled to each other. For example, some non-limiting examples of mobile devices include mobile stations, cellular (cell) phones, smart phones, session initiation protocol (SIP) phones, laptops, personal computers (PCs), notebooks, netbooks, smartbooks, tablets, personal digital assistants (PDAs), and a wide variety of embedded systems (e.g., corresponding to the "Internet of Things" (IoT)).

[0025] The mobile device may also be a car or other transportation vehicle, a remote sensor or actuator, a robot or robotic device, a satellite radio, a global positioning system (GPS) device, an object tracking device, a drone, a multi-rotor aircraft, a quadcopter, a remote control device, a consumer and / or wearable device such as glasses, a wearable camera, a virtual reality device, a smart watch, a health or fitness tracker, a digital audio player (e.g., an MP3 player), a camera, a game console, etc. The mobile device may also be a digital home or smart home device (such as home audio, video, and / or multimedia devices), an appliance, a vending machine, a smart lighting device, a home security system, a smart meter, etc. The mobile device may also be a smart energy device, a security device, a solar panel or solar array, a municipal infrastructure device that controls electrical power (e.g., a smart grid), lighting, water supply, etc., an industrial automation and enterprise device, a logistics controller, and / or agricultural equipment, etc. Further, the mobile device may provide connected medical or telemedicine support, such as remote health care. Telemedicine devices may include telemedicine monitoring devices and telemedicine management devices, whose communications may be given priority or priority access relative to other types of information, for example, in terms of priority access for transmission of critical service data and / or associated QoS for transmission of critical service data.

[0026] Wireless communication between RAN 104 and UE 106 can be described as utilizing an air interface. Transmission from a base station (e.g., base station 108) to one or more UEs (e.g., similar to UE 106) over an air interface can be referred to as downlink (DL) transmission. According to certain aspects of the present disclosure, the term downlink can refer to point-to-multipoint transmission originating at a base station (e.g., base station 108). Another way to describe this scheme can be to use the term broadcast channel multiplexing. Transmission from a UE (e.g., UE 106) to a base station (e.g., base station 108) can be referred to as uplink (UL) transmission. According to further aspects of the present disclosure, the term uplink can refer to point-to-point transmission originating at a UE (e.g., UE 106).

[0027] In some examples, access to the air interface may be scheduled, wherein a scheduling entity (e.g., a base station 108) allocates resources for communication among some or all devices and equipment within its service area or cell. Within the present disclosure, as discussed further below, a scheduling entity may be responsible for scheduling, assigning, reconfiguring, and releasing resources for one or more scheduled entities (e.g., UEs 106). That is, for scheduled communications, multiple UEs 106 (which may be scheduled entities) may utilize resources allocated by the scheduling entity 108.

[0028] Base station 108 is not the only entity that can act as a scheduling entity. That is, in some examples, a UE can act as a scheduling entity, scheduling resources for one or more scheduled entities (e.g., one or more other UEs). For example, a UE can communicate directly with other UEs in a peer-to-peer or device-to-device manner and / or in a relay configuration.

[0029] like Figure 1 As illustrated, the scheduling entity 108 may broadcast downlink traffic 112 to one or more scheduled entities (e.g., one or more UEs 106). Broadly speaking, the scheduling entity 108 is a node or device responsible for scheduling traffic in a wireless communication network, which includes downlink traffic 112 and, in some examples, uplink traffic 116 from one or more scheduled entities (e.g., one or more UEs 106) to the scheduling entity 108. On the other hand, a scheduled entity (e.g., a UE 106) is a node or device that receives downlink control information 114 (including, but not limited to, scheduling information (e.g., grants), synchronization or timing information, or other control information) from another entity in the wireless communication network (such as the scheduling entity 108). The scheduled entity 106 may further send uplink control information 118 to the scheduling entity 108, including, but not limited to, scheduling requests or feedback information or other control information.

[0030] In addition, uplink and / or downlink control 118 and / or 118 information and / or uplink and / or downlink traffic 116 and / or 112 may be sent on a waveform that may be time-divided into frames, subframes, time slots and / or symbols. As used herein, a symbol may refer to a time unit that carries one resource element (RE) per subcarrier in an orthogonal frequency division multiplexing (OFDM) waveform. A time slot may carry 7 or 14 OFDM symbols. A subframe may refer to a duration of 1 ms. Multiple subframes or time slots may be grouped together to form a single frame or radio frame. Within the present disclosure, a frame may refer to a predetermined duration (e.g., 10 ms) for wireless transmission, wherein each frame is composed of, for example, 10 subframes of 1 ms each. Of course, these definitions are not required, and any suitable scheme for organizing waveforms may be utilized, and the various time divisions of waveforms may have any suitable duration.

[0031] Generally, the base stations 108 may include a backhaul interface for communicating with a backhaul portion 120 of the wireless communication system 100. The backhaul portion 120 may provide a link between the base stations 108 and the core network 102. Additionally, in some examples, a backhaul network may provide interconnections between the respective base stations 108. Various types of backhaul interfaces may be employed, such as a direct physical connection using any suitable transport network, a virtual network, etc.

[0032] The core network 102 may be part of the wireless communication system 100 and may be independent of the radio access technology used in the RAN 104. In some examples, the core network 102 may be configured according to 5G standards, such as 5G Core (5GC). In other examples, the core network 102 may be configured according to 4G Evolved Packet Core (EPC) or any other suitable standard or configuration.

[0033] Reference now Figure 2 , by way of illustrative example and not limitation, a schematic illustration of a radio access network (RAN) 200 according to some aspects of the present disclosure is provided. In some examples, the RAN 200 may be similar to the RAN described above and Figure 1 The RAN 104 shown is the same.

[0034] The geographic area covered by the RAN 200 may be divided into a plurality of cellular regions (cells) that may be uniquely identified by a user equipment (UE) based on an identity broadcast from an access point or base station within the geographic area. Figure 2 Cells 202, 204, 206, and 208 are illustrated, each of which may include one or more sectors (not shown). A sector is a sub-area of ​​a cell. All sectors within a cell are served by the same base station. A radio link within a sector may be identified by a single logical identifier belonging to the sector. In a cell divided into sectors, multiple sectors within a cell may be formed by multiple groups of antennas, each of which is responsible for communicating with a UE in a portion of the cell.

[0035] Various base station arrangements can be used. Figure 2 , two base stations (base station 210 and base station 212) are shown in cells 202 and 204. A third base station (base station 214) is shown as controlling a remote radio head (RRH) 216 in cell 206. That is, the base station may have an integrated antenna, or may be connected to an antenna or RRH 216 by a feeder cable. In the illustrated example, cells 202, 204, and 206 may be referred to as macro cells because base stations 210, 212, and 214 support cells with large sizes. In addition, base station 218 is shown in cell 208, which may overlap with one or more macro cells. In this example, cell 208 may be referred to as a small cell (e.g., a small cell, a micro cell, a pico cell, a femto cell, a home base station, a home node B, a home eNode B, etc.) because base station 218 supports a cell with a relatively small size. Cell size settings may be performed according to system design and component constraints.

[0036] It should be understood that RAN 200 may include any number of wireless base stations and cells. In addition, relay nodes may be deployed to extend the size or coverage area of ​​a given cell. Base stations 210, 212, 214, 218 provide wireless access points to the core network for any number of mobile devices. In some examples, base stations 210, 212, 214, and / or 218 may be similar to those described above and Figure 1 The illustrated scheduling entities 108 are the same or similar.

[0037] Figure 2 Also included is an unmanned aerial vehicle (UAV) 220, which may be a drone or a quadcopter. UAV 220 may be configured to act as a base station, or more specifically, a mobile base station. That is, in some examples, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of a mobile base station (such as UAV 220).

[0038] Within the RAN 200, cells may include UEs that may communicate with one or more sectors of each cell. In addition, each base station 210, 212, 214, 218, and 220 may be configured to provide access to the core network 102 (see FIG. 1 ) for all UEs in the corresponding cell. Figure 1 ) access point. For example, UEs 222 and 224 may communicate with base station 210; UEs 226 and 228 may communicate with base station 212; UEs 230 and 232 may communicate with base station 214 via RRH 216; UE 234 may communicate with base station 218; and UE 236 may communicate with mobile base station 220. In some examples, UEs 222, 224, 226, 228, 230, 232, 234, 236, 238, 240, and / or 242 may be described above and Figure 1 The illustrated UE / scheduled entity 106 is the same or similar. In some examples, UAV 220 (e.g., a quadcopter) can be a mobile network node and can be configured to act as a UE. For example, UAV 220 can operate within cell 202 by communicating with base station 210.

[0039] In another aspect of RAN 200, sidelink signals may be used between UEs without having to rely on scheduling or control information from a base station. Sidelink communications may be utilized in, for example, a device-to-device (D2D) network, a peer-to-peer (P2P) network, a vehicle-to-vehicle (V2V) network, a vehicle-to-everything (V2X) network, and / or other suitable sidelink networks. For example, two or more UEs (e.g., UE 238, 240, and 242) may communicate with each other using sidelink signals 237 without relaying the communication through a base station. In some examples, UE 238, 240, and 242 may each act as a scheduling entity or a transmitting sidelink device and / or a scheduled entity or a receiving sidelink device to schedule resources and communicate sidelink signals 237 between them without relying on scheduling or control information from a base station. In other examples, two or more UEs (e.g., UE 226 and 228) within the coverage area of ​​a base station (e.g., base station 212) may also communicate sidelink signals 227 via a direct link (sidelink) without transmitting the communication through base station 212. In this example, base station 212 may allocate resources to UEs 226 and 228 for sidelink communications.

[0040] In order to obtain a low block error rate (BLER) for transmissions over the air interface while still achieving very high data rates, channel coding may be used. That is, wireless communications may typically utilize a suitable error-correcting block code. In a typical block code, an information message or sequence is split into code blocks (CBs), and an encoder (e.g., a codec) at the transmitting device then mathematically adds redundancy to the information message. Utilizing this redundancy in the encoded information message may improve the reliability of the message, thereby enabling correction of any bit errors that may occur due to noise.

[0041] Data decoding can be implemented in a variety of ways. In early 5G NR specifications, user data is decoded using quasi-cyclic low-density parity check (LDPC) with two different basemaps: one basemap is used for large code blocks and / or high code rates, and the other basemap is used for other cases. Control information and the physical broadcast channel (PBCH) are decoded based on nested sequences using polar decoding. For these channels, puncturing, shortening, and repetition are used for rate matching.

[0042] Aspects of the present disclosure may be implemented using any suitable channel codes. Various implementations of base stations and UEs may include suitable hardware and capabilities (eg, encoders, decoders, and / or codecs) to utilize one or more of these channel codes for wireless communications.

[0043] In the RAN 200, the ability of a UE to communicate while moving (independent of its location) is called mobility. The various physical channels between the UE and the RAN 200 are generally established, maintained, and released under the control of an access and mobility management function (AMF). In some scenarios, the AMF may include: a security context management function (SCMF) and a security anchor function (SEAF) that performs authentication. The SCMF may manage security contexts for both control plane functionality and user plane functionality in whole or in part.

[0044] In various aspects of the present disclosure, the RAN 200 may utilize DL-based mobility or UL-based mobility to implement mobility and handover (i.e., the UE's connection is transferred from one radio channel to another). In a network configured for DL-based mobility, during a call with a scheduling entity or at any other time, the UE may monitor various parameters of the signal from its serving cell and various parameters of neighboring cells. Based on the quality of these parameters, the UE may maintain communication with one or more of the neighboring cells. During this time, if the UE moves from one cell to another, or if the signal quality from the neighboring cell exceeds the signal quality from the serving cell for a given amount of time, the UE may perform a handover or handover from the serving cell to the neighboring (target) cell. For example, the UE 224 may move from a geographic area corresponding to its serving cell 202 to a geographic area corresponding to a neighboring cell 206. When the signal strength or quality from the neighboring cell 206 exceeds the signal strength and quality of its serving cell 202 for a given amount of time, the UE 224 may send a report message indicating this to its serving base station 210. In response, UE 224 may receive the handover command, and the UE may proceed with the handover to cell 206 .

[0045] In a network configured for UL-based mobility, the network may select a serving cell for each UE using a UL reference signal from each UE. In some examples, base stations 210, 212, and 214 / 216 may broadcast unified synchronization signals (e.g., unified primary synchronization signal (PSS), unified secondary synchronization signal (SSS), and unified physical broadcast channel (PBCH)). UEs 222, 224, 226, 228, 230, and 232 may receive unified synchronization signals, derive carrier frequency and slot timing from these synchronization signals, and send uplink pilots or reference signals in response to the derived timing. The uplink pilot signal sent by a UE (e.g., UE 224) may be received concurrently by two or more cells (e.g., base stations 210 and 214 / 216) within RAN 200. Each of these cells may measure the strength of the pilot signal, and the radio access network (e.g., one or more of the base stations 210 and 214 / 216 and / or a central node within the core network) may determine a serving cell for the UE 224. As the UE 224 moves through the RAN 200, the RAN 200 may continue to monitor the uplink pilot signals sent by the UE 224. When the signal strength or quality of the pilot signal measured by the neighboring cell exceeds the signal strength or quality measured by the serving cell, the RAN 200 may hand over the UE 224 from the serving cell to the neighboring cell with or without notifying the UE 224.

[0046] Although the synchronization signals transmitted by base stations 210, 212 and 214 / 216 may be uniform, the synchronization signal may not identify a specific cell, but may identify a zone of multiple cells operating on the same frequency and / or using the same timing. Using zones in a 5G network or other next generation communication network implements an uplink-based mobility framework and improves the efficiency of both the UE and the network, because the number of mobility messages that need to be exchanged between the UE and the network can be reduced.

[0047] In various specific implementations, the air interface in the radio access network 200 may utilize licensed spectrum, unlicensed spectrum, or shared spectrum. Licensed spectrum generally provides exclusive use of a portion of the spectrum with the help of a mobile network operator purchasing a license from a government regulator. Unlicensed spectrum provides shared use of a portion of the spectrum without the need for a government-granted license. Although access to unlicensed spectrum generally still requires compliance with some technical regulations, access is generally available to any operator or device. Shared spectrum may fall between licensed spectrum and unlicensed spectrum, where access to the spectrum may require some technical regulations or restrictions, but the spectrum may still be shared by multiple operators and / or multiple RATs. For example, a license holder of a portion of a licensed spectrum may provide licensed shared access (LSA) to share the spectrum with other parties (e.g., with appropriate licensor-determined conditions to obtain access).

[0048] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. A similar naming issue sometimes occurs 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).

[0049] 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 frequency bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, so the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designation FR4-a 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.

[0050] In view of the above aspects, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used in this document, it can broadly refer to frequencies that may be less 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 in this document, it can 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.

[0051] Devices communicating in the radio access network 200 may utilize one or more multiplexing techniques and multiple access algorithms to enable simultaneous communication of various devices. For example, the 5G NR specification utilizes orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) to provide multiple access for UL transmissions from UEs 222 and 224 to the base station 210, and provides multiplexing for DL ​​transmissions from the base station 210 to one or more UEs 222 and 224. In addition, for UL transmissions, the 5G NR specification provides support for discrete Fourier transform spread OFDM (DFT-s-OFDM) with CP (also known as single carrier FDMA (SC-FDMA)). However, within the scope of the present disclosure, multiplexing and multiple access are not limited to the above schemes, and may be provided using time division multiple access (TDMA), code division multiple access (CDMA), frequency division multiple access (FDMA), sparse code division multiple access (SCMA), resource extension multiple access (RSMA), or other suitable multiple access schemes. In addition, multiplexing of DL transmissions from base station 210 to UEs 222 and 224 may be provided using time division multiplexing (TDM), code division multiplexing (CDM), frequency division multiplexing (FDM), orthogonal frequency division multiplexing (OFDM), sparse code division multiplexing (SCM), or other suitable multiplexing schemes.

[0052] The equipment in the radio access network 200 may also utilize one or more duplex algorithms. Duplex refers to a point-to-point communication link in which two endpoints can communicate with each other in two directions. Full-duplex means that two endpoints can communicate with each other at the same time. Half-duplex means that only one endpoint can transmit information to the other endpoint at a time. Half-duplex simulation is often implemented for wireless links using time division duplex (TDD). In TDD, transmissions in different directions on a given channel are separated from each other using time division multiplexing. That is, in some scenarios, a channel is dedicated to transmission in one direction, while at other times, the channel is dedicated to transmission in another direction, where the direction can change very quickly, for example, several times per time slot. In wireless links, full-duplex channels generally rely on physical isolation of transmitters and receivers and suitable interference cancellation techniques. Full-duplex simulation is often implemented for wireless links by utilizing frequency division duplex (FDD) or space division duplex (SDD). In FDD, transmissions in different directions can operate at different carrier frequencies (e.g., within a paired spectrum). In SDD, transmissions in different directions on a given channel are separated from each other using spatial division multiplexing (SDM). In other examples, full-duplex communication may be implemented within an unpaired spectrum (e.g., within a single carrier bandwidth), where transmissions in different directions occur within different sub-bands of the carrier bandwidth. This type of full-duplex communication may be referred to herein as sub-band full-duplex (SBFD), also known as flexible duplex.

[0053] Will refer to Figure 3 Various aspects of the present disclosure are described with reference to the OFDM waveforms schematically illustrated in . It will be appreciated by those skilled in the art that various aspects of the present disclosure may be applied to SC-FDMA waveforms in substantially the same manner as described below herein. That is, while some examples of the present disclosure may focus on OFDM links for clarity, it will be appreciated that the same principles may also apply to SC-FDMA waveforms.

[0054] Reference now Figure 3 , illustrates an expanded view of an exemplary subframe 302 showing an OFDM resource grid according to some aspects of the present disclosure. However, as will be readily appreciated by those skilled in the art, the physical (PHY) transmission structure for any particular application may differ from the examples described herein depending on any number of factors. Here, time is in the horizontal direction, in units of OFDM symbols; and frequency is in the vertical direction, in units of subcarriers of a carrier.

[0055] Resource grid 304 can be used to schematically represent the time-frequency resources for a given antenna port. That is, in a multiple-input multiple-output (MIMO) implementation with multiple available antenna ports, a corresponding plurality of resource grids 304 can be available for communication. Resource grid 304 is divided into a plurality of resource elements (REs) 306. RE (which is 1 subcarrier×1 symbol) is the smallest discrete portion of the time-frequency grid and contains a single complex value representing data from a physical channel or signal. Depending on the modulation utilized in a particular implementation, each RE can represent one or more bits of information. In some examples, a block of REs can be referred to as a physical resource block (PRB), or more simply a resource block (RB) 308, which contains any suitable number of consecutive subcarriers in the frequency domain. In one example, an RB can include 12 subcarriers, a number that is independent of the parameter set used. In some examples, depending on the parameter set, an RB can include any suitable number of consecutive OFDM symbols in the time domain. Within the present disclosure, it is assumed that a single RB (such as RB 308) corresponds entirely to communication in a single direction (transmission or reception for a given device).

[0056] A collection of contiguous or discontinuous resource blocks may be referred to herein as a resource block group (RBG), a subband, or a bandwidth part (BWP). A collection of subbands or BWPs may span the entire bandwidth. Scheduling a scheduled entity (e.g., a UE) for downlink, uplink, or sidelink transmission typically involves scheduling one or more resource elements 306 within one or more subbands or bandwidth parts (BWPs). Thus, a UE typically utilizes only a subset of a resource grid 304. In some examples, an RB may be the smallest resource unit that may be allocated to a UE. Thus, the more RBs scheduled for a UE, and the higher the modulation scheme selected for the air interface, the higher the data rate for the UE. The RB may be scheduled by a scheduling entity such as a base station (e.g., a gNB, an eNB, etc.), or may be self-scheduled by a UE implementing D2D sidelink communication.

[0057] In this illustration, RB 308 is shown as occupying a portion of the entire bandwidth of subframe 302, with some subcarriers illustrated above and below RB 308. In a given implementation, subframe 302 may have a bandwidth corresponding to any number of one or more RBs 308. Furthermore, in this illustration, RB 308 is shown as occupying a portion of the entire duration of subframe 302, although this is only one possible example.

[0058] Each 1 ms subframe 302 may include one or more adjacent time slots. Figure 3In the example shown, as an illustrative example, a subframe 302 includes four time slots 310. In some examples, a time slot may be defined according to a specified number of OFDM symbols with a given cyclic prefix (CP) length. For example, a time slot may include 7 or 14 OFDM symbols with a nominal CP. Additional examples may include micro-time slots with shorter durations (e.g., one to three OFDM symbols), which are sometimes referred to as shortened transmission time intervals (TTIs). These micro-time slots or shortened transmission time intervals (TTIs) may be sent in some cases by occupying resources scheduled for ongoing time slot transmissions for the same UE or different UEs. Any number of resource blocks may be utilized within a subframe or time slot.

[0059] An expanded view of one of the time slots 310 illustrates that the time slot 310 includes a control region 312 and a data region 314. In general, the control region 312 may carry control channels, and the data region 314 may carry data channels. Of course, a time slot may contain full DL, full UL, or at least one DL portion and at least one UL portion. Figure 3 The illustrated structure is merely exemplary in nature and different slot structures may be utilized and these slot structures may include one or more of each of the control region and the data region.

[0060] Although in Figure 3 Although not illustrated in the figure, each RE 306 within the RB 308 may be scheduled to carry one or more physical channels, including control channels, shared channels, data channels, etc. Other REs 306 within the RB 308 may also carry pilot or reference signals. These pilot or reference signals may be provided to a receiving device to perform channel estimation of the corresponding channel, which may enable coherent demodulation / detection of control channels and / or data channels within the RB 308.

[0061] In some examples, time slot 310 may be used for broadcast, multicast, groupcast, or unicast communications. For example, broadcast, multicast, or groupcast communications may refer to point-to-multipoint transmissions from one device (e.g., a base station, UE, or other similar device) to other devices. Here, broadcast communications are delivered to all devices, while multicast or groupcast communications are delivered to multiple intended recipient devices. Unicast communications may refer to point-to-point transmissions from one device to a single other device.

[0062] In an example of cellular communication over a cellular carrier via a Uu interface, for DL ​​transmission, a scheduling entity (e.g., a base station) may allocate one or more REs 306 (e.g., within a control region 312) to one or more scheduled entities (e.g., UEs) to carry DL control information including one or more DL control channels, such as a physical downlink control channel (PDCCH). The PDCCH carries downlink control information (DCI) including, but not limited to, power control commands (e.g., one or more open-loop power control parameters and / or one or more closed-loop power control parameters), scheduling information, grants, and / or assignments of REs for DL ​​transmission and UL transmission. The PDCCH may also carry hybrid automatic repeat request (HARQ) feedback transmissions, such as acknowledgements (ACKs) or negative acknowledgements (NACKs). HARQ is a technique known to those of ordinary skill in the art, in which the integrity of packet transmissions may be checked for accuracy at the receiving side, for example, using any appropriate integrity check mechanism, such as a checksum or a cyclic redundancy check (CRC). If the integrity of the transmission is confirmed, an ACK may be sent, and if the integrity of the transmission is not confirmed, a NACK may be sent. In response to the NACK, the sending device may transmit a HARQ retransmission, which may enable append combining, incremental redundancy, and the like.

[0063] The base station may also allocate one or more REs 306 (e.g., in the control region 312 or the data region 314) to carry other DL signals, such as a demodulation reference signal (DMRS); a phase tracking reference signal (PT-RS); a channel state information (CSI) reference signal (CSI-RS); and a synchronization signal block (SSB). The SSB may be broadcast at regular intervals based on a periodicity (e.g., 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms). The SSB includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast control channel (PBCH). The UE may utilize the PSS and SSS to achieve radio frame, subframe, time slot, and symbol synchronization in the time domain, to identify the center of the channel (system) bandwidth in the frequency domain, and to identify the physical cell identity (PCI) of the cell.

[0064] The PBCH in the SSB may also include a master information block (MIB) containing various system information and parameters for decoding a system information block (SIB). The SIB may be, for example, SystemInformationType 1 (SIB1), which may include various additional system information. The MIB and SIB1 together provide minimum system information (SI) for initial access. Examples of system information sent in the MIB may include, but are not limited to, subcarrier spacing (e.g., default downlink parameter set), system frame number, configuration of the PDCCH control resource set (CORESET) (e.g., PDCCH CORESET0), cell barring indicator, cell reselection indicator, grid offset, and search space for SIB1. Examples of remaining minimum system information (RMSI) sent in SIB1 may include, but are not limited to, random access search space, paging search space, downlink configuration information, and uplink configuration information. The base station may also send other system information (OSI).

[0065] In an UL transmission, a scheduled entity (e.g., a UE) may utilize one or more REs 306 to carry UL control information (UCI) including one or more UL control channels (such as a physical uplink control channel (PUCCH)) to a scheduling entity. The UCI may include various packet types and categories, including pilots, reference signals, and information configured to enable or assist in decoding uplink data transmissions. Examples of uplink reference signals may include sounding reference signals (SRS) and uplink DMRS. In some examples, the UCI may include a scheduling request (SR), i.e., a request for the scheduling entity to schedule an uplink transmission. Here, in response to the SR sent on the UCI, the scheduling entity may send downlink control information (DCI), which may schedule resources for uplink packet transmissions. The UCI may also include HARQ feedback, channel state feedback (CSF) (such as a CSI report), or any other suitable UCI.

[0066] In addition to control information, one or more REs 306 (e.g., within the data region 314) may also be allocated for data. Such data may be carried on one or more traffic channels, such as, for DL ​​transmissions, on a physical downlink shared channel (PDSCH); or for UL transmissions, on a physical uplink shared channel (PUSCH). In some examples, one or more REs 306 within the data region 314 may be configured to carry other signals, such as one or more SIBs and DMRS. In some examples, the PDSCH may carry multiple SIBs, not limited to the SIB1 discussed above. For example, OSI may be provided in these SIBs (e.g., SIB2 and above).

[0067] In an example of sidelink communication over a sidelink carrier via a ProSe (ProSe) PC5 interface, a control region 312 of a time slot 310 may include a physical sidelink control channel (PSCCH) including sidelink control information (SCI) sent by an initiating (transmitting) sidelink device (e.g., a Tx V2X device or other Tx UE) toward a set of one or more other receiving sidelink devices (e.g., an Rx V2X device or other Rx UE). A data region 314 of the time slot 310 may include a physical sidelink shared channel (PSSCH) including sidelink data sent by the initiating (transmitting) sidelink device in resources reserved by the transmitting sidelink device on the sidelink carrier via the SCI. Other information may also be sent via various REs 306 within the time slot 310. For example, HARQ feedback information may be sent from the receiving sidelink device to the transmitting sidelink device in a physical sidelink feedback channel (PSFCH) within the time slot 310. Additionally, one or more reference signals may be sent within slot 310, such as a sidelink SSB, a sidelink CSI-RS, a sidelink SRS, and / or a sidelink positioning reference signal (PRS).

[0068] These physical channels described above are typically multiplexed and mapped to transport channels for processing at the medium access control (MAC) layer. The transport channels carry blocks of information called transport blocks (TBs). Based on the modulation and coding scheme (MCS) and the number of RBs in a given transmission, the transport block size (TBS), which may correspond to the number of bits of information (e.g., the amount of bits of information), may be a controlled parameter.

[0069] Figure 1 , Figure 2 and Figure 3 The channels or carriers illustrated are not necessarily all channels or carriers that may be utilized between devices, and one of ordinary skill in the art will recognize that other channels or carriers may be utilized in addition to those illustrated, such as other traffic, control, and feedback channels.

[0070] New technologies such as FR2 NR uplink carrier aggregation (UL-CA) enable the use of relatively large bandwidths and high data rates. However, the network may not automatically grant the maximum number of component carriers in response to each resource request from a given UE. Instead, and by way of example, the network may rely on a buffer status report (BSR) received from a given UE as a factor to be considered when determining whether to enable multiple component carriers (CCs) for a given UE and thus enable cross-carrier scheduling. The BSR can be short (5 bits in length) or long (8 bits in length). The short BSR can report to the network the amount of data stored in the buffer for any one logical channel group by including one of a total of 32 index values ​​in the BSR. The range of short BSR index values ​​is index 0 (indicating 0 bytes of data in a given LCG buffer) to index 31 (indicating 0.15 megabytes of data in a given LCG buffer). The range of long BSR index values ​​is index 0 (indicating 0 bytes of data in a given LCG buffer) to index 254 (indicating 81 megabytes of data in a given LCG buffer). Although the 8 bits of the long BSR take up more resources than the 5 bits of the short BSR, the long BSR provides more information at a finer level of granularity than the short BSR. Table I below presents the buffer size levels (e.g., buffer size values ​​in bytes) for the 5-bit short buffer size field. Table II below presents the buffer size levels (e.g., buffer size values ​​in bytes) for the 8-bit long buffer size field.

[0076]

[0077] Buffer status reporting is currently undertaken by the MAC entity of a given UE. According to current practice, whether to report a short BSR or a long BSR is determined based on the number of LCGs that have data that can be used for transmission when a MAC PDU containing a BSR is to be constructed (e.g., generated). Specifically, for regular and periodic BSRs, if more than one LCG has data that can be used for transmission when a MAC PDU containing a BSR is to be constructed, the MAC entity reports (e.g., transmits, sends) a long BSR for all LCGs that have data that can be used for transmission. Otherwise (i.e., if only one LCG has data that can be used for transmission when a MAC PDU containing a BSR is to be constructed), the MAC entity will report a short BSR.

[0078] Current practice may result in a situation where a given UE is configured with a suboptimal configuration. Some examples of suboptimal configurations include, but are not limited to, a bandwidth lower than would otherwise be available, a single component carrier when an additional component carrier is available, or a scheduling scheme that does not change in response to the type, priority, or amount of data to be transmitted in the uplink direction (also referred to as immutable scheduling). The foregoing list is exemplary and not limiting. A suboptimal configuration may occur when a UE reports a short BSR and the network takes an undesirable amount of time (e.g., a relatively long time given, for example, the type or priority of data to be transmitted in the uplink direction) to react to the short BSR and delays the activation of a component carrier that the UE can use to relatively quickly send data waiting to be uploaded in its buffer. In this delay example, as well as other examples within the scope of the present disclosure, the network's delay in activating additional component carriers may negatively impact trunking efficiency gains. On the other hand, the content of the short BSR may inform the network that, in a given set of circumstances, a single component carrier is sufficient to carry the accumulated and waiting data, based on the known maximum component carrier channel capacity, and the decision not to activate additional (or all available component carriers) is a valid decision. By way of example, a decision by the network not to add a component carrier may result in reduced resource waste. The decision may, for example, reduce padding data that might otherwise be used to fill potentially unused resources (of the additional component carrier).

[0079] According to various aspects of the present disclosure, techniques for BSR reporting with relaxed LCG requirements are described herein. Current LCG requirements necessitate that if more than one LCG has data available for transmission when a MAC PDU containing a BSR is to be constructed, the MAC entity of the UE will report (e.g., transmit) a long BSR for all LCGs that have data available for transmission. Thus, the LCG requirements effectively prohibit the use of a long BSR when only one LCG has data available for transmission at the time a MAC PDU containing a BSR is to be constructed. The LCG requirements may negatively impact BSR reporting, for example, but not limited to, in use cases involving customer premises equipment (CPE). For example, in a CPE use case, it is expected that only one LCG will be configured because, for example, a CPE service profile may be data-centric for enterprise applications. The CPE use case may be comparable to a smartphone use case, where a smartphone (e.g., a smartphone-like UE) may have voice (e.g., voice over new radio (VONR)) plus data and other applications running in parallel. Relaxation of the LCG requirements may optimize, for example, activation of uplink component carriers by the network and improve performance of the network, for example, by optimizing scheduling and usage of resources by the network.

[0080] Figure 4 An example of a wireless communication system 400 including a terrestrial RAN 402 and a non-terrestrial RAN 404 (e.g., a non-terrestrial network (NTN)) is illustrated. The wireless communication system 400 may be a 5G wireless communication system (5GS), which may correspond to, for example, Figure 1 The illustrated wireless communication system 100. The ground RAN 402 may correspond to, for example Figure 2 The illustrated RAN 200. Each of the terrestrial RAN 402 and the non-terrestrial RAN 404 may be associated with a respective geographic area. Therefore, each of the terrestrial RAN 402 and the non-terrestrial RAN 404 may provide 5G services within the corresponding respective geographic area. For example, the terrestrial RAN 402 may include one or more base stations 406 (one of which is shown for convenience), each base station serving one or more wireless communication devices 408. The terrestrial RAN 402 may be further coupled to a core network (CN) 418 for communication of user plane and control plane signaling and data.

[0081] In some examples, the non-terrestrial RAN 404 may include one or more ground base stations 426 (one of which is shown for convenience), and the satellite 410a may provide a backhaul link to the core network 418. In this example, the non-terrestrial network 404 includes both terrestrial RAN components and non-terrestrial RAN components. The non-terrestrial RAN 404 also includes a satellite gateway 414 (or earth station) to relay control plane and user plane communications between the satellite 410a and the core network 418. In some examples, the satellite 410a may route communications to / from the satellite gateway 414 via an inter-satellite link (ISL) through one or more additional satellites 410b.

[0082] According to some aspects, the non-terrestrial RAN 404 may include a satellite 410a that operates as a base station (e.g., a gNB) to serve one or more UEs 412 within a satellite coverage area. According to other aspects, a satellite gateway or another ground entity may act as a base station. In some examples, the satellite coverage area may include one or more fixed tracking areas (TAs), each of which includes one or more cells (not shown) served by the satellite 410a. Depending on the type of satellite, each cell may be defined relative to a fixed or mobile satellite beam point. For example, the satellite 410a may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, or a highly elliptical orbit (HEO). By way of example, a LEO satellite may orbit the earth at an altitude between 300 kilometers (km) and 2,000 km and produce a beam coverage area size between 100 km and 500 km. A MEO satellite may orbit the earth at an altitude between 8,000 km and 25,000 km and produce a beam coverage area size between 100 km and 500 km. GEO satellites may orbit the Earth at an altitude of 35,786 km and produce a beam footprint size between 200 km and 1,000 km. NTNs are not limited to aerospace vehicles (e.g., satellites). According to some examples, the NTN may include a network or network segment that is transmitted using an aerospace or aerospace vehicle. An aerospace vehicle may include a high altitude platform (HAP) that includes an unmanned aerial vehicle system (UAS) (similar to UAV 220). By way of example, a UAS may include, but is not limited to, a tethered (e.g., quasi-steady state) UAS, a lighter-than-air UAS, and a heavier-than-air UAS.

[0083] Communications via non-terrestrial RAN 404 may be referred to as NTN communications. The round trip time (including propagation delay) between the wireless communication device 412, one or more satellites (e.g., satellite 410a, satellite 410b), and the satellite gateway 414 will be greater than the round trip time between the wireless communication device 412 and the relatively nearby ground base station 426. The round trip time (e.g., as an indicator of latency) may be considered by the wireless communication device 412 when choosing whether to send a short BSR or a long BSR. In the example of NTN communications, a long BSR may provide a base station (e.g., located in satellite 410a or at satellite gateway 414) with a better estimate of the amount of data waiting for uplink transmission than a short BSR. A better estimate of the amount of data waiting for uplink transmission may inform the base station of its decision regarding the scheduling rate for use in conjunction with the wireless communication device 412. A better estimate of the amount of data waiting for uplink transmission (obtained via a long BSR) and an increased probability of obtaining a scheduling rate commensurate with the amount of data waiting for uplink transmission may improve the overall communication quality of user applications. BSR with higher granularity (eg, in scenarios that may include NTN communications) may help overcome propagation delays and other delays that contribute to latency, and may help provide scheduling patterns that may improve overall communication quality for user applications and improve user experience.

[0084] Figure 5 is a call flow diagram 500 illustrating communications between a user equipment 502 and a network access node 504 according to some aspects of the present disclosure. The user equipment 502 may be, for example, in conjunction with Figure 1 , Figure 2 and / or Figure 4 Any user equipment or scheduled entity shown and described. The network access node 504 may be, for example, a combination of Figure 1 , Figure 2 and / or Figure 4 Any scheduling entity, network access node, or base station shown and described. In some examples, the network access node 504 can be implemented as a converged base station or a decomposed base station. In a decomposed base station architecture, the network access node can include one or more of a central unit (CU), a distributed unit (DU), or a radio unit (RU).

[0085] exist Figure 5In the example shown, UE 502 may buffer (e.g., accumulate and temporarily store) data in any buffer of the first buffer 521 to the nth buffer 523, where n is a positive integer, such as 4, 8, or another integer. Data may be associated with a logical channel group (LCG). An LCG may be a set of logical channels / resource blocks (LC / RBs). Each RB may have its own buffer. In one example, all signaling radio bearers (SRBs) may be part of one LCG. The first data radio bearer (DRB) and the second DRB may be another LCG; the third DRB may be another LCG. The LCG BSR reports the sum of all data waiting on the associated radio bearer. In some examples, UE 502 may have more than one LCG, and the first buffer 521 to the nth buffer 523 may store data associated with corresponding LCGs in more than one LCG. The first buffer 521 to the nth buffer 523 may be located, for example, in the memory 508 of UE 502.

[0086] like Figure 5 As shown, UE 502 may detect a BSR trigger 506. BSR trigger 506 may be any event or occurrence that triggers UE 502 to send (e.g., report, transmit) a BSR. In one example, BSR trigger 506 may be associated with resource allocation for uplink data. For example, a BSR may be triggered when resource allocation detection circuitry / function 515 determines that resources are allocated to a given LCG; however, no data is available for the given LCG, or data that can be used for uplink transmission belongs to a different LCG with a higher priority than the given LCG.

[0087] In another example, the UE may detect the BSR trigger 506 based on the expiration of the periodic BSR timer 510 while there is still data to be sent in the buffer associated with the given LCG. The periodic BSR timer 510 may reside in the timer circuit 514 of the UE 502. For example, the UE 502 may start the periodic BSR timer 510 when the UE 502 sends a previous BSR. The next BSR may be triggered in response to the expiration of the periodic BSR timer 510 and the accumulation of data in the corresponding buffer (e.g., any of the first buffer 521 to the nth buffer 523), wherein the data is accumulated during the time between the transmission of the previous BSR and the expiration of the periodic BSR timer 510.

[0088] In another example, the UE 502 may detect the BSR trigger 506 based on the retransmit BSR timer 512 expiring while there is still data to be sent in the buffer associated with the given LCG. The retransmit BSR timer 512 may reside in the timer circuit 514 of the UE 502. For example, the UE 502 may start the retransmit BSR timer 512 when the UE 502 sends a first BSR, and the UE 502 may stop and reset the retransmit BSR timer 512 based on, for example, receiving an uplink grant from the network access node 504 in response to the sending of the first BSR. If the retransmit BSR timer 512 expires before the UE 502 receives the uplink grant, the retransmit BSR timer 512 may trigger the UE 502 to retransmit the BSR.

[0089] In some examples, if the UE 502 detects a BSR trigger 506, for example, by detecting an allocation of resources, expiration of a periodic BSR timer 510, or expiration of a retransmission BSR timer 512 (all as exemplified above), the UE 502 may decide whether to report (e.g., transmit) a short BSR 516 or a long BSR. This decision may currently be based on whether one LCG or more than one LCG has data available for transmission when a MAC PDU containing a BSR is to be constructed.

[0090] According to some aspects, if more than one LCG has data available for transmission when a MAC PDU containing a BSR is to be constructed, then the UE 502 may report a long BSR for all LCGs having data available for transmission at 518. However, if only one LCG has data available for transmission when a MAC PDU containing a BSR is to be constructed, then the UE 502 may report a short BSR for the only one LCG at 518.

[0091] For example, when UE 502 detects a BSR trigger 506 and UE 502 determines that a single LCG of UE 502 has data to send (e.g., data in the first buffer 521 associated with the LCG), UE 502 may determine to send a short BSR associated with the LCG (to report the amount of data associated with the LCG that is ready for uplink transmission).

[0092] According to some aspects of the present invention, as an alternative to deciding whether to transmit a short BSR or a long BSR based on the amount of LCGs with data waiting to be uploaded when constructing a MAC PDU containing a BSR, a UE (e.g., a MAC entity of the UE) may determine whether to transmit a long BSR or a short BSR based on a comparison of a decision point value with a threshold. The decision point value may be a metric. In the example provided herein, the decision point value may be a value determined by a buffer status report (BSR) type. In some examples, the value determined by the BSR type may be based on a corresponding value assigned to at least one of the following: a peak power envelope of a wireless communication device, a data transmission rate historically obtained by the wireless communication device, a number of component carriers that can be scheduled for a buffer for fully uploading data (e.g., where the number corresponds to an amount), a cost function, an amount of data associated with a logical channel group waiting to be sent on the uplink, a type of wireless communication device, or a communication delay of a wireless communication device. For example, the UE may transmit a long buffer status report for an LCG with a certain amount of data waiting to be sent on the uplink in response to a decision point value exceeding a threshold. Alternatively, the UE may transmit a short buffer status report for the LCG in response to a decision point value being equal to or less than a threshold.

For example, the wireless communication device 600 may be such as Figure 1 , Figure 2 , Figure 4 and / or Figure 5 A scheduled entity (e.g., UE) exemplified by any one or more of .

[0094] According to various aspects of the present disclosure, a processing system 602 including one or more processors, such as a processor 604, may be used to implement an element or any portion of an element or any combination of elements.

[0095] In some examples, processor 604 may be implemented via a baseband or modem chip, and in other implementations, processor 604 may include multiple devices distinct and other than a baseband or modem chip (e.g., in such scenarios that may work together to implement the examples discussed herein). And as mentioned above, various hardware arrangements and components outside of a baseband modem processor may be used in implementations, including RF chains, power amplifiers, modulators, buffers, interleavers, adders / summers, etc.

[0096] In this example, the processing system 602 may be implemented using a bus architecture, which is generally represented by bus 606.

Bus 606 communicatively couples together various circuits including one or more processors, which are generally represented by processor 604, memory 608, and computer-readable media, which are generally represented by computer-readable media 610. Bus 606 may also link various other circuits such as timing sources, peripherals, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further.

[0097] The bus interface 612 provides an interface between the bus 606 and the transceiver 614. The transceiver 614 can be a wireless transceiver. The transceiver 614 can provide a component for communicating with various other devices through a transmission medium (e.g., an air interface). The transceiver 614 can be further coupled to one or more antenna arrays (hereinafter antenna array 616). The bus interface 612 further provides an interface between the bus 606 and a user interface 618 (e.g., a keypad, a display, a touch screen, a speaker, a microphone, control features, etc.). Of course, such a user interface 618 is optional and can be omitted in some examples. In addition, the bus interface 612 further provides an interface between the bus 606 and a power supply 620 of the wireless communication device 600.

[0098] The processor 604 is responsible for managing the bus 606 and general processing, which includes executing software stored on the computer-readable medium 610. The software, when executed by the processor 604, causes the processing system 602 to perform various functions described below for any specific device. The computer-readable medium 610 and the memory 608 can also be used to store data manipulated by the processor 604 when executing the software. According to some aspects of the present disclosure, the data may include data in any buffer of the first buffer 621 to the nth buffer 623, and / or data in the set of data transmission rate history data 627 described herein.

By way of example, non-transient computer readable media include magnetic storage devices (e.g., hard disks, floppy disks, magnetic strips), optical disks (e.g., compact discs (CDs) or digital versatile discs (DVDs)), smart cards, flash memory devices (e.g., cards, sticks or key drives), random access memories (RAMs), read-only memories (ROMs), programmable ROMs (PROMs), erasable PROMs (EPROMs), electrically erasable PROMs (EEPROMs), registers, removable disks, and any other suitable medium for storing software and / or instructions that can be accessed and read by a computer.

The computer readable medium 610 may be embodied in a computer program product or article of manufacture. By way of example, a computer program product or article of manufacture may include a computer readable medium in packaging materials. In some examples, the computer readable medium 610 may be part of the memory 608.

In some examples, the communication and processing circuit 641 may include one or more hardware components that provide a physical structure that performs processes related to wireless communication (e.g., signal reception and / or signal transmission) and signal processing (e.g., processing received signals and / or processing signals for transmission). For example, the communication and processing circuit 641 may include one or more transmit / receive chains.

[0102] In some implementations where communication involves receiving information, the communication and processing circuitry 641 may obtain or identify information from a component of the wireless communication device 600 (e.g., from a transceiver 614 that receives information via radio frequency signaling or some other type of signaling suitable for an applicable communication medium), process (e.g., decode) the information, and output the processed information. For example, the communication and processing circuitry 641 may output the information to another component of the processor 604, to the memory 608, or to the bus interface 612. In some examples, the communication and processing circuitry 641 may receive one or more of a signal, a message, other information, or any combination thereof. In some examples, the communication and processing circuitry 641 may receive information via one or more channels. In some examples, the communication and processing circuitry 641 may include functionality for components for receiving. In some examples, the communication and processing circuitry 641 may include functionality for components for processing, including components for demodulating, components for decoding, and the like.

[0103] In some implementations where communication involves transmitting (e.g., sending) information, the communication and processing circuitry 641 may obtain or identify the information (e.g., from another component of the processor 604, the memory 608, or the bus interface 612), process (e.g., modulate, encode, etc.) the information, and output the processed information. For example, according to some aspects of the present disclosure, the communication and processing circuitry 641 may obtain data stored in the memory 608 and may process the obtained data.

[0104] In some examples, the communication and processing circuitry 641 may obtain information and output the information to the transceiver 614 (e.g., the transceiver sends the information via radio frequency signaling or some other type of signaling suitable for the applicable communication medium). In some examples, the communication and processing circuitry 641 may transmit one or more of a signal, a message, other information, or any combination thereof. In some examples, the communication and processing circuitry 641 may transmit information via one or more channels. In some examples, the communication and processing circuitry 641 may include functionality for components for transmitting (e.g., components for sending). In some examples, the communication and processing circuitry 641 may include functionality for components for generating (which include components for modulating, components for encoding, etc.). In some examples, the communication and processing circuitry 641 may be configured to receive and process uplink traffic and uplink control messages (e.g., similar to) via the antenna array 616 and the transceiver 614. Figure 1 116 and uplink control 118) and processes and sends downlink traffic and downlink control messages (e.g., similar to Figure 1 downlink traffic 112 and downlink control 114).

[0105] The communication and processing circuitry 641 may be further configured to execute communication and processing instructions 651 (eg, software) stored on the computer-readable medium 610 to implement one or more functions described herein.

[0106] In some aspects of the invention, processor 604 may include one or more buffers that are located in Figure 6 621 to nth buffer 623 associated with memory 608. Of course, the first buffer 621 to nth buffer 623 are not limited to being associated with memory 608; other locations and components may perform the functions of the first buffer 621 to nth buffer 623 or be incorporated into the first buffer 621 to nth buffer 623. The first buffer 621 to nth buffer 623 may accumulate and (e.g., temporarily) store data waiting for uplink transmission. The data may be grouped according to logical channels. Therefore, the first buffer 621 to nth buffer 623 may accumulate and store data of corresponding logical channel groups in multiple logical channel groups. Although the first buffer 621 to nth buffer 623 may be under the control of the processing system 602, in some examples, the first buffer 621 to nth buffer 623 may be configured to execute buffer instructions 653 (e.g., software) stored on the computer-readable medium 610 to implement one or more functions described herein.

[0107] In some aspects of the present disclosure, the processor 604 may include a timer circuit 642. The timer circuit 642 may be configured for various functions, including, for example, setting, starting, stopping, resetting, and restarting various timers. The various timers may include, but are not limited to, a periodic BSR timer 644 and a retransmission BSR timer 645. The periodic BSR timer 644 and the retransmission BSR timer 645 may be similar to those in combination with Figure 5 The periodic BSR timer 510 and the retransmission BSR timer 512 shown and described above are shown and described. Figure 5 These types of timers are described, so their description will not be repeated for the sake of brevity. Timer circuit 642 can be configured to execute timer instructions 652 (e.g., software) stored on computer-readable medium 610 to implement one or more functions described herein. Although they can generally respond to timer instructions 652, according to some aspects, periodic BSR timer 644 can be configured to execute periodic BSR timer instructions 654 (e.g., software) and retransmit BSR timer 645 can be configured to execute retransmit BSR timer instructions 655 (e.g., software), all of which are stored, for example, on computer-readable medium 610, to implement one or more functions described herein.

[0108] In some aspects of the present disclosure, the processor 604 may include a BSR trigger detection circuit 646. The BSR trigger detection circuit 646 may be configured for various functions, including, for example, detecting values ​​of various parameters, states of flags, and / or other indicia of an instruction to trigger a BSR report and / or to begin (e.g., start) a given type of BSR timer. The given type of BSR timer may be, for example, a periodic BSR timer 644 as shown and described above, a retransmission BSR timer 645 as shown and described above, and / or any other timer that may be directly or indirectly associated with the generation and / or transmission of a BSR. The BSR trigger detection circuit 646 may include a resource allocation detection circuit 625, similar to the Figure 5 The resource allocation detection circuit / function 525. The BSR trigger detection circuit 646 can be used to detect the BSR trigger 506, such as in combination with Figure 5 As shown and described. Because the above combination Figure 5 Some exemplary types of BSR triggers and their detection are shown and described, so for the sake of brevity, further description of the BSR trigger detection circuit 646 will be omitted. The BSR trigger detection circuit 646 may be configured to execute BSR trigger detection instructions 656 (e.g., software) stored on the computer-readable medium 610 (these instructions may include resource allocation detection instructions (not shown)) to implement one or more functions described herein.

[0109] In some aspects of the present disclosure, the processor 604 may include a long / short BSR decision circuit 647. The long / short BSR decision circuit 647 may be configured for various functions, including, for example, deciding whether to transmit a long buffer status report for a logical channel group having a certain amount of data waiting for uplink transmission in response to a decision point value exceeding a threshold, or to transmit a short buffer status report for the logical channel group in response to the decision point value being equal to or less than the threshold. According to some aspects, the decision point value may be a value determined by a buffer status report (BSR) type. In some examples, the value determined by the BSR type may be based on a corresponding value assigned to at least one of: a peak power envelope of the wireless communication device, a data transmission rate historically obtained by the wireless communication device, a number of component carriers available for being scheduled for a buffer for fully uploading the saved data, a cost function, an amount of data waiting for uplink transmission associated with the logical channel group, a type of wireless communication device, or a communication latency of the wireless communication device.

[0110] In some aspects, long / short BSR decision circuit 647 may operate in conjunction with, for example, communication and processing circuit 641 to determine, for example, a corresponding value (eg, a first corresponding value) of a peak power envelope that may be assigned to a wireless communication device.

[0111] In some aspects, the long / short BSR decision circuit 647 may work in conjunction with, for example, the communication and processing circuit 641 and the memory 608 to determine, for example, a corresponding value (e.g., a second corresponding value) to assign to the data transmission rate. Figure 6 As shown, the memory 608 of the wireless communication device 600 can store data transmission rate history data 627.

[0112] In some aspects, long / short BSR decision circuit 647 may work in conjunction with, for example, communication and processing circuit 641 to determine a corresponding value (eg, a third corresponding value) assigned to, for example, the number of component carriers allocated or scheduled for wireless communication device 600 .

[0113] In some aspects, the long / short BSR decision circuit 647 may work in conjunction with, for example, the communication and processing circuit 641 to determine, for example, a corresponding value (e.g., a fourth corresponding value) assigned to the cost function. For example, the corresponding value assigned to the cost function may be obtained by comparing a first amount of power required to send the amount of data using a single component carrier having a first channel capacity with a second amount of power required to send the amount of data in multiple component carriers having a collective channel capacity.

[0114] In some aspects, long / short BSR decision circuit 647 may work in conjunction with, for example, communication and processing circuit 641 to determine a respective value (eg, a fifth respective value), for example, of an amount assigned to data associated with a logical channel group.

[0115] In some aspects, the long / short BSR decision circuit 647 may operate in conjunction with, for example, the communication and processing circuit 641 to determine, for example, a corresponding value (eg, a sixth corresponding value) associated with a type of wireless communication device.

[0116] In some aspects, long / short BSR decision circuit 647 may operate in conjunction with, for example, communication and processing circuit 641 to determine a corresponding value (eg, a seventh corresponding value) associated with, for example, a communication delay of a wireless communication device.

[0117] According to each of the aspects and examples provided above, the long / short BSR decision circuit 647 may be configured to execute long / short BSR decision instructions 657 (eg, software) stored on the computer-readable medium 610 to implement one or more functions described herein.

[0118] Figure 7 7 is a flow chart illustrating an exemplary process 700 (e.g., a method of wireless communication) at a wireless communication device (e.g., at a scheduled entity, at a user equipment (UE)) according to some aspects of the present disclosure. The process 700 may be performed in a wireless communication network (such as, for example, Figure 1 , Figure 2 , Figure 4 , Figure 5 and / or Figure 6 As described below, some or all of the illustrated features may be omitted in certain implementations within the scope of the present disclosure, and some of the illustrated features may not be required in all implementations. In some examples, process 700 may be performed in conjunction with Figure 6 The process 700 is performed by the described and illustrated wireless communication device 600. In some examples, the process 700 can be performed by any suitable device or means for performing the functions or algorithms described herein.

[0119] At block 702, the wireless communication device may detect a buffer status report trigger. Figure 6 The BSR trigger detection circuit 646 shown and described may provide means for detecting a buffer status report trigger.

[0120] At block 704, the wireless communication device may obtain a decision point value. According to some aspects, the decision point value may be a value determined by a buffer status report (BSR) type. In some examples, the value determined by the BSR type may be based on a corresponding value assigned to at least one of: a peak power envelope of the wireless communication device, a data transmission rate historically obtained by the wireless communication device, a number of component carriers that can be scheduled for a buffer to fully upload the saved data, a cost function, an amount of data associated with the logical channel group waiting for uplink transmission, a type of the wireless communication device, or a communication latency of the wireless communication device. For example, the above may be combined with Figure 6 The long / short BSR decision circuit 647 shown and described may provide means for obtaining a decision point value.

[0121] As above combined Figure 6 The decision point value may be based on a first corresponding value of a peak power envelope assigned to the wireless communication device. The first corresponding value may be obtained by the wireless communication device based on known specifications of the wireless communication device. In some examples, the first corresponding value may increase as the peak power envelope increases. For example, the above combination Figure 6 The illustrated and described communications and processing circuitry 641 may provide means for obtaining a corresponding value associated with a peak power envelope of a UE.

[0122] In some examples, the decision point value may be based on a corresponding value assigned to the data transmission rate. In some examples, the wireless communication device may obtain the corresponding value from historical data stored in a memory of the wireless communication device. In some examples, the corresponding value assigned to the data transmission rate may be obtained from or using data transmission rate history data 627 stored in the memory 608 of the wireless communication device 600. For example, the above combination Figure 6 The communication and processing circuitry 641 shown and described may provide means for obtaining corresponding values ​​from historical data stored in a memory of the wireless communication device. The data may be stored, for example, in a data transmission rate history data 627 section of the memory 608 of the wireless communication device.

[0123] In some aspects, the decision point value may be based on a corresponding value assigned to a number of component carriers allocated to the wireless communication device. In some examples, the number of component carriers allocated or scheduled to the wireless communication device may be determined based on, for example, scheduling information received by the wireless communication device. According to some aspects, the corresponding value assigned to the number of component carriers allocated or scheduled for the wireless communication device may increase as the number of component carriers increases. For example, the above combination Figure 6 The illustrated and described communication and processing circuitry 641 may provide means for obtaining a corresponding value associated with a number of component carriers allocated or scheduled to a UE.

[0124] In some aspects, the decision point value may be based on a corresponding value assigned to a cost function. In some examples, the corresponding value assigned to the cost function may be determined at the wireless communication device. For example, the corresponding value assigned to the cost function may be obtained by comparing a first amount of power required to send the amount of data using a single component carrier having a first channel capacity with a second amount of power required to send the amount of data in multiple component carriers having a collective channel capacity. According to some aspects, the corresponding value assigned to the cost function may increase as the first amount of power decreases relative to the second amount of power. For example, in combination with Figure 6The communication and processing circuitry 641 shown and described may provide means for obtaining a corresponding value of the cost function. Figure 6 The communication and processing circuitry 641 shown and described may provide means for comparing a first amount of power required to transmit the amount of data utilizing a single component carrier having a first channel capacity to a second amount of power required to transmit the amount of data in multiple component carriers having a collective channel capacity.

[0125] In some aspects, the decision point value may be based on a corresponding value assigned to an amount of data associated with the logical channel group. In some examples, the corresponding value assigned to an amount of data associated with the logical channel group may be determined by the wireless communication device, for example, by determining an amount of data stored at the wireless communication device associated with the logical channel group and associating the determined amount of data with the corresponding value. For example, a table stored at the wireless communication device may cross-reference certain values ​​(e.g., the corresponding value) with a predetermined range of values ​​for data that may be stored in a buffer, such as a buffer such as a buffer that is associated with the logical channel group. Figure 6 According to some aspects, the corresponding value assigned to the amount of data associated with the logical channel group may decrease as the amount of data decreases. For example, the above combination Figure 6 The illustrated and described communications and processing circuitry 641 may provide means for obtaining a corresponding value assigned to an amount of data associated with a logical channel group.

[0126] In some aspects, the decision point value may be based on a corresponding value associated with the type of wireless communication device. In some examples, the corresponding value associated with the type of wireless communication device may be determined based on a parameter stored at the wireless communication device, where the parameter identifies the type of wireless communication device. By way of example and not limitation, the first type may be customer premises equipment; the second type may be a smartphone with long term evolution (LTE) capabilities; and the third type may be a smartphone with 5G capabilities. For example, according to some aspects, the sixth corresponding value associated with the type of wireless communication device may be greater for non-customer premises equipment than for customer premises equipment. For example, in combination with Figure 6 The illustrated and described communication and processing circuitry 641 may provide means for obtaining a corresponding value associated with a type of wireless communication device assigned to a UE.

[0127] In some aspects, the decision point value may be based on a corresponding value associated with a measure or expected value of the communication delay of the wireless communication device. In some examples, the corresponding value of the communication delay of the wireless communication device can be obtained by measuring the end-to-end delay. For example, the end-to-end delay of the communication path between the wireless communication device 412, the satellite 410a and the satellite gateway 414 can be measured. Alternatively, the round-trip time between the wireless communication device 412, the satellite 410a and the satellite gateway 414 can be measured. Other ways to obtain delays and other delay measurements are within the scope of the present disclosure. According to some aspects described herein, the delay may be referred to as the communication delay of the wireless communication device. According to some aspects, a lower value representing the communication delay of the wireless communication device may be better than a relatively high value. According to some aspects, the value representing the communication delay of the wireless communication device may be referred to as the seventh corresponding in this article. An application associated with the communication of the wireless communication device may notify (e.g., made by a base station) a decision on the importance of the value representing the delay. For example, relatively low latency may be less important (and may be given less weight) in applications related to massive machine type communications (mMTC) than in applications related to ultra-reliable low latency communications (uRLLC). Figure 6 The communication and processing circuitry 641 shown and described may provide means for obtaining a corresponding value associated with a communication latency of a wireless communication device.

[0128] At 706, the wireless communication device may determine whether the obtained decision point value exceeds a threshold. At 708, if the decision point value exceeds the threshold, the wireless communication device may transmit (e.g., report) a long buffer status report for the logical channel group having a first amount of data waiting for uplink transmission in response to the decision point value exceeding the threshold. At 710, if the decision point value does not exceed the threshold, the wireless communication device may transmit (e.g., report) a short buffer status report for the logical channel group in response to the decision point value being equal to or less than the threshold. Of course, the general representation of the threshold and the decision as to whether the decision point value exceeds the threshold is provided only as an example. In other examples, the decision to transmit the long buffer status report may be made in response to the decision point value being equal to or greater than the threshold, while the decision to transmit the short buffer status report may be made in response to the decision point value being less than the threshold). In other examples, the decision to send the long buffer status report may be made in response to the decision point value being less than (or less than or equal to) the threshold, while the decision to transmit the short buffer status report may be made in response to the decision point value being greater than or equal to (or greater than) the threshold.

[0129] Of course, in the above examples, the circuits included in the processor 604 are provided only as examples. Other components for performing the described processes or functions may be included in various aspects of the present disclosure, including but not limited to storage in the computer readable medium 610 or Figure 1 , Figure 2, Figure 4 , Figure 5 and / or Figure 6 Any other suitable device or component described in any of the above and using, for example, Figure 4 , Figure 5 and / or Figure 7 Instructions of the described processes and / or algorithms.
