Abstract
Description
TECHNICAL FIELD
[0001] Exemplary embodiments of the present disclosure relate generally to the field of communications, and in particular, to an apparatus, method, device, and computer-readable storage medium for handling semi-persistent scheduling (SPS) configurations using a Time Advance (TA) framework.
BACKGROUND ART
[0002] Communication technologies are continuously evolving to provide efficient and reliable solutions for utilizing wireless communication networks. Each new generation presents unique technical challenges to address various scenarios and processes required for connectivity and services of devices connected to wireless networks. Efforts have been made to develop improved 5th Generation (5G), pre-5G, 6G or later communication systems to meet the increasing demand for wireless data traffic since the introduction of 4th Generation (4G) communication systems.
[0003] Multiple-Input Multiple-Output (MIMO) is one of the key technologies in new radio systems, and while it is important to identify and define the necessary enhancements for uplink MIMO, the required enhancements for downlink MIMO facilitate the utilization of large-scale antenna arrays. Several enhancements have been proposed to facilitate the deployment of multiple Transmission Reception Points (multi-TRP) for Uplink (UL) via two Timing Advance (TA) values, and enhanced UL power control may bring further improvements to UL performance.

[0018] The principles of this disclosure are described below with reference to some illustrative embodiments. These embodiments are provided for illustrative purposes only and should not imply any limitation on the scope of this disclosure, but should be understood as an aid to those skilled in the art in understanding and implementing this disclosure. The disclosures described herein can be implemented in various ways other than those described below.
[0019] In the following descriptions and claims, unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this disclosure belongs.
[0020] The terms "one embodiment," "embodiment," and "exemplary embodiment" in this disclosure indicate that the described embodiments may include certain features, structures, or characteristics, but not all embodiments necessarily include those features, structures, or characteristics. Furthermore, such terms do not necessarily refer to the same embodiment. Also, when certain features, structures, or characteristics are described in relation to one embodiment, it is considered within the knowledge of those skilled in the art to reflect those features, structures, or characteristics in relation to other embodiments, whether or not they are explicitly stated.
[0021] In this specification, terms such as “first,” “second,” etc., may be used to describe various elements, but it should be understood that these elements should not be limited by these terms. These terms are simply used to distinguish one element from another. Without departing from the scope of the exemplary embodiments, for example, the first element may be called the second element, and similarly, the second element may be called the first element. The term “and / or” as used herein includes any combination of one or more of the enumerated terms.
[0022] The terms used in this specification are used solely for the purpose of describing specific embodiments, and are not intended to limit the illustrative embodiments. As used in this specification, the singular forms are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprise", "have", "possess" and / or "include" as used in this specification indicate the presence of the stated features, elements and / or components, etc., but do not preclude the presence or addition of one or more other features, elements, components and / or combinations thereof. As used in this specification, the expressions "at least one of the following: <recitation of two or more elements>", "at least one of <recitation of two or more elements>" and similar expressions, in which the recitation of two or more elements is connected by "and" or "or", mean at least any one of those elements, at least any two or more of those elements, or at least all of those elements.
[0023] As used in the present application, the term "circuit" may refer to one or more, or alternatively all, of the following. (a) Hardware-only circuits (such as analog circuits and / or digital circuits) (b) Combinations of hardware circuits and software as follows (where applicable) (i) A combination of analog and / or digital hardware circuits and software (e.g., firmware), and (ii) Any portion of a hardware processor with software (including a digital signal processor), software and memory that cooperate to cause an apparatus such as a mobile phone or a server to perform various functions, and (c) A hardware circuit and / or processor such as a microprocessor or part of a microprocessor that requires software (e.g., firmware) for operation (provided that the software may be absent if not required for operation)
[0024] This definition of circuit applies to all uses of this term in the present application, including in the claims. As a further example, as used in the present application, the term circuit also includes a mere hardware circuit or processor (alternatively, a plurality of processors), or a part of a hardware circuit or processor and a software and / or firmware implementation associated therewith (alternatively, therewith). The term circuit also includes, for example, where applicable to an element of a particular claim, a baseband integrated circuit or processor integrated circuit for a mobile device, or a similar integrated circuit in a server, a cellular network device, or other computing or network device.
[0025] As used herein, the term "cellular network" refers to a network operating in accordance with any suitable radio access technology defined by standards such as Long Term Evolution (LTE), LTE-Advanced (LTE-A), New Radio, Wideband Code Division Multiple Access (WCDMA (registered trademark)), High Speed Packet Access (HSPA), and Narrowband IoT (NB-IoT). Further, communication between a terminal device and a network device of the cellular network may be performed in accordance with any suitable communication protocol, including but not limited to 4th Generation (4G), 4.5G, future 5th Generation (5G) communication protocols, and / or other currently known or future developed protocols. Embodiments of the present disclosure may be applied in various cellular networks. In view of the rapid development in communications, future communication technologies and systems in which the present disclosure may be embodied will of course also emerge. The scope of the present disclosure should not be construed as being limited to the aforementioned systems only.
[0026] As used herein, the term “network device” refers to any device in a cellular network through which terminal devices access the data network and receive services exposed by other network devices in the cellular network. In some examples, a network device may provide or implement network functions of the fifth-generation communication system (5GS) of the cellular network (e.g., the core network). In some examples, a network device may be located in the RAN of the 5GS. A network device may be part of a satellite, base station (BS) or access point (AP), and depending on the terminology and technology applied, may be, for example, a node B (NodeB or NB), an evolutionary node B (eNodeB or eNB), an NR NB (also called a gNB), a remote radio unit (RRU), a radio header (RH), a remote radio head (RRH), a relay, or a low-power node such as a femtonode or piconode. A gNB may include a central unit (CU) and one or more distributed DUs. Femtonodes and piconodes are small base stations with limited range.
[0027] The term "terminal device" refers to a device in a cellular network communication system such as 5GS that is capable of wireless (e.g., radio) communication with NR-RAN of a fifth-generation communication system (5GS). Exemplary, rather than limited, terminal devices may also be called wireless communication devices, user devices (UE), subscriber stations (SS), portable subscriber stations, mobile stations (MS), or access terminals (AT). Examples of terminal devices include, but are not limited to, mobile phones, cellular phones, smartphones, voice over IP (VoIP) phones, wireless local loop phones, tablets, wearable devices, personal digital assistants (PDAs), portable computers, desktop computers, image capture devices such as digital cameras, game terminals, music storage and playback devices, in-vehicle wireless terminals, wireless endpoints, mobile stations, laptop embedded devices (LEEs), laptop mounted devices (LMEs), USB dongles, smart devices, wireless customer premises equipment (CPEs), IoT devices, watches or other wearable devices, head-mounted displays (HMDs), vehicles, drones, medical devices and medical applications (e.g., remote surgery), industrial equipment and industrial applications (e.g., robots and / or wireless devices operating in industrial and / or automated processing chain situations), consumer electronics, and devices operating on commercial and / or industrial wireless networks. In the following description, the terms “terminal device,” “communication device,” “terminal,” “user device,” and “UE” may be used interchangeably.
[0028] Releasing or clearing any downlink assignments set for a serving cell configured with two TAGs only affects the uplinks of the TAGs involved; that is, the UL channels or configurations associated with the other TAG may remain unchanged. This means that an action may be described if the TAT of the other serving cell TAG is still active while the other has expired.
[0029] Any UL transmission can be associated with a TAG, for example, through a Transmit Setting Indicator (TCI) state or TAG association, but clearing a configured downlink assignment (also known as "SPS") is not so straightforward. Downlink (DL) SPS settings may be transmitted by the network via any TRP (Transmit / Receive Point) or using a first or second designated TCI state. The first designated TCI state may be associated with a first TAG, and the second designated TCI may be associated with a second TAG. The main issue is how to clear only the necessary and configured DL SPS settings when the TAT of one of the two TAGs associated with the serving cell expires.
[0030] Based on the above, the exemplary embodiments of the present disclosure provide a solution for processing SPS settings using a time advance (TA) framework, and more particularly, a two-time advance (TA) framework. In the exemplary embodiments of the present disclosure, the device may determine that the first time alignment timer (TAT) of the first timing advance group (TAG) is in a first state, the second TAT of the second TAG is in a second state, determine that a semi-persistent scheduling (SPS) setting is associated with the first TAG, and perform an operation on the SPS setting.
[0031] In the context of this disclosure, when the TAT of a first TAG associated with a serving cell expires and the TAT of a second TAG associated with the same serving cell is still active, if a PUCCH resource used to indicate a configured downlink assignment, such as a configured SPS setting, or feedback to a configured downlink assignment is associated with the first TAG, that configured downlink assignment or SPS setting may be cleared. This ensures that if one TAT expires for a serving cell that is unable to send physical uplink control channel (PUCCH) feedback based on a PUCCH resource or TAG association, only the configured downlink assignment or SPS setting is cleared or deactivated.
[0032] Figure 1 shows an example of a network environment 100 in which an exemplary embodiment of the present disclosure can be implemented. The environment 100 may be part of a communication network and may include a plurality of terminal devices and network devices, such as terminal device 110 and network device 120. For example, terminal device 110 may be implemented as a user device (UE) or access terminal (AT), and network device 120 may be implemented as a satellite (eNB) or base station (BS). Network device 120 may transmit various data to terminal device 110 via the network environment 100.
[0033] To transmit data and / or control information, the terminal device 110 may communicate with the network device 120. The link from the network device 120 to the terminal device 110 is called a downlink (DL), and the link from the terminal device 110 to the network device 120 is called an uplink (UL).
[0034] The terminal device 110 and the network device 120 are described in the communication environment 100 of Figure 1, but embodiments of the present disclosure can be equally applied to any other suitable communication devices communicating with each other. In other words, embodiments of the present disclosure are not limited to the illustrative scenario of Figure 1. In this regard, it should be noted that although the terminal device is schematically shown as a mobile phone and the network device 120 as a satellite in Figure 1, these illustrations are illustrative and do not imply any limitation. In other embodiments, the terminal device 110 and the network device 120 may be any other communication devices, for example, any other wireless communication device.
[0035] The specific number of communication devices and communication links shown in Figure 1 are for illustrative purposes only and should not be considered as limitations. The communication environment 100 may include any suitable number of communication devices and any suitable number of communication links for carrying out embodiments of the present disclosure. Furthermore, it should be understood that wired communication (if necessary) may be conducted between all communication devices, as well as various wireless communications.
[0036] Figure 2 shows a flowchart of a method according to some embodiments of the present disclosure. For discussion purposes, Method 200 will be described with reference to Figure 1. Although Method 200 is described with reference to Figure 1, it will be understood that Method 200 may be applied in the same way to other similar communication scenarios.
[0037] In method 200, block 202 may determine that a device which may be implemented as a terminal device 110 or a network device 120 is in a first state, and that the first time alignment timer (TAT) of the first timing advance group (TAG) is in a second state, and the second TAT of the second TAG is in a second state. The first state may indicate that the first TAT has expired, and the second state may indicate that the second TAT is operating.
[0038] In block 204, the device may determine that a semi-persistent scheduling (SPS) setting is associated with the first TAG. In some embodiments, the device may determine that an SPS setting is associated with the first TAG by determining that a physical uplink control channel (PUCCH) resource for the SPS setting is associated with the first TAG.
[0039] In some other embodiments, the device may determine that a PUCCH resource for SPS configuration is associated with a first TAG by determining that the uplink transmit configuration indicator (TCI) state or joint TCI state to which the PUCCH resource follows is associated with the first TAG. Alternatively, or further, the device may determine that a PUCCH resource for SPS configuration is associated with a first TAG by determining that the downlink control information (DCI) that activates the SPS configuration is associated with the first TAG. The DCI may be transmitted via a set of control resources associated with the first TAG.
[0040] In other embodiments, the device may determine that a PUCCH resource for SPS configuration is associated with a first TAG by determining that the PUCCH resource for SPS configuration is associated with a first TAG based on radio resource control (RRC) signaling. The RRC signaling may associate the PUCCH resource with the SPS configuration.
[0041] In some embodiments, the device may determine that an SPS setting is associated with a first TAG by determining that the downlink state or Joint Transmit Setting Indicator (TCI) state of the physical downlink shared channel (PDSCH) for SPS setting is associated with the first TAG.
[0042] In other embodiments, the device may determine that an SPS setting is associated with a first TAG by determining that the downlink state or joint transmit setting indicator (TCI) state of a physical downlink control channel (PDCCH) that activates the SPS setting is associated with a core set pool index. One or more uplink TCI states or joint TCI states may be activated or indicated for a core set pool index and associated with the first TAG.
[0043] In block 206, the device may perform operations on the SPS setting. For example, the device may release the SPS setting based on a determination that the SPS setting is associated with a first TAG. Alternatively, or further, the device may suspend the SPS setting based on a determination that the SPS setting is associated with a first TAG until the PUCCH resource for the SPS is reconfigured for a TAG with a valid timing advance (TA).
[0044] Alternatively, or further, the device may suspend the SPS setting until the first TAT recovers, based on the determination that the SPS setting is associated with a first TAG. In some embodiments, the device may release the suspended SPS setting based on the determination that both the first TAT and the second TAT are in a first state. The device may deactivate the SPS setting based on the determination that the SPS setting is associated with a first TAG.
[0045] In some embodiments, the device may activate the SPS setting based on an activation command. Alternatively, or further, the device may release Hybrid Auto-Retransmission Request (HARQ) feedback based on the release of the SPS setting.
[0046] In the context of this disclosure, if the device determines that the TAT of a first TAG or any one of the TAGs associated with a serving cell has expired, and the TAT of a second TAG or other TAG associated with the same serving cell is still active, the device may clear the configured downlink assignment or SPS setting if a PUCCH resource used to indicate feedback to the configured downlink assignment or SPS setting is associated with the first TAG.
[0047] In the context of this disclosure or in certain embodiments, when the device determines that the TAT of a first TAG or any one of the TAGs associated with a serving cell has expired, the device may also consider the TAT of a second TAG or other TAG associated with the same serving cell to have expired. In some examples, this occurs when the first TAG is the device's secondary TAG. In other examples, when the first TAG is the device's primary TAG, the device may consider all TATs of the second TAG or other TAGs associated with any serving cell to have expired. Consequently, the PUCCH resource used to indicate feedback to configured downlink assignments or SPS settings is also released, so the device may clear all configured downlink assignments or SPS settings associated with the serving cell.
[0048] In some embodiments, the device may determine the PUCCH resource from DCI (Downlink Control Information) that activates a configured downlink allocation or SPS setting. The DCI may be associated with a first or second TAG through a Control Resource Set (CORESET) used to provide the DCI, and the CORESET is associated with a coreset pool index. The coreset pool index may be further associated with the TAG through a TCI state associated with the TAG identifier.
[0049] For example, in some embodiments, a DL TCI state or joint TCI state associated with a downlink assignment or SPS setting PDSCH is associated with a coreset pool index, and the device may determine that a downlink assignment or SPS setting is associated with a first TAG by determining that one or more UL TCI states or one or more joint TCI states activated or indicated for the coreset pool index are associated with a first TAG (via RRC).
[0050] In some embodiments, a DL TCI state or joint TCI state associated with a DCI or downlink PDCCH that activates an SPS PDSCH assignment is associated with a coreset pool index, and the device may determine that a downlink assignment or SPS setting is associated with a first TAG by determining that one or more UL TCI states or one or more joint TCI states activated or indicated for the coreset pool index are associated (via RRC) with a first TAG.
[0051] In some embodiments, the device may determine a PUCCH resource from RRC signaling used to associate a PUCCH resource with a configured downlink assignment or SPS setting. In some examples, the device may determine that a PUCCH resource associated with a downlink assignment or SPS setting is associated with a first TAG by determining that a UL TCI state or joint TCI state is associated with a PUCCH resource and that the UL TCI state or joint TCI state is associated with a first TAG.
[0052] In other embodiments, the device may determine that a PUCCH resource associated with a downlink assignment or SPS setting is associated with the first TAG by determining that a DL TCI state or joint TCI state associated with a downlink assignment PDCCH is associated with a coreset pool index, and that one or more UL TCI states or one or more joint TCI states activated or indicated for the coreset pool index are associated with the first TAG.
[0053] Alternatively, or further, the device may stop rather than release the SPS configuration until the network reconfigures the PUCCH resource for the SPS to a TAG with a valid TA, or until the TA of the PUCCH's TAG recovers. The device may also deactivate the SPS configuration when the TAT expires for the first TAG of the associated PUCCH, while the SPS configuration may be activated by an explicit activation command from the network.
[0054] In some other embodiments, if the TATs of both TAGs expire, for example, if both the first TAT and the second TAT expire, the device may release the stopped SPS setting. Note that the association of a PUCCH to a TAG may be determined based on the UL TCI state or joint TCI state that the PUCCH resource is configured to follow (i.e., whether it follows a first indicated TCI state or a second indicated TCI state) and based on the association of the TCI state to the TAG identifier.
[0055] An SPS setting may include a PUCCH setting for Hybrid Automatic Retransmission Request (HARQ) feedback, and the PUCCH setting may indicate which TRP it is associated with. When the TAT expires for the TAG to which an SPS PUCCH setting is associated, the PUCCH resource for sending HARQ feedback is also released and becomes unavailable at the time of TAT expiration, so the corresponding SPS setting may also be released. Note that an SPS setting does not need to be associated with any TRP and may be activated / deactivated via any TRP. Retransmission of an SPS setting may also be scheduled via any TRP.
[0056] The following table shows examples of elements in SPS configuration information. SPS configurations may be used to configure semi-persistent transmission of downlinks. Multiple downlink SPS configurations may be configured for a single bandwidth portion (BWP) of a serving cell. The parameter PUCCH-ResourceId may indicate a resource identifier.
[0057] In some embodiments, an apparatus capable of performing Method 200 (e.g., a terminal device 110 or a network device 120) may include means for performing each step of Method 200. These means can be implemented in any suitable form. For example, they may be implemented as circuits or software modules.
[0058] In some embodiments, the device includes means for determining that the first time alignment timer (TAT) of a first timing advance group (TAG) is in a first state and the second TAT of a second TAG is in a second state; means for determining that a semi-persistent scheduling (SPS) setting is associated with the first TAG; and means for performing operations on the SPS setting. The first state indicates that the first TAT has expired, and the second state indicates that the second TAT is operating.
[0059] In some embodiments, the device includes means for determining that a physical uplink control channel (PUCCH) resource for SPS configuration is associated with a first TAG. In some embodiments, the device includes means for determining that an uplink transmit configuration indicator (TCI) state or joint TCI state to which the PUCCH resource follows is associated with the first TAG.
[0060] In some embodiments, the device includes means for determining that downlink control information (DCI) that activates an SPS setting and is transmitted via a control resource set associated with a first TAG is associated with the first TAG. In some embodiments, the device includes means for determining that a PUCCH resource for an SPS setting is associated with the first TAG based on radio resource control (RRC) signaling that associates a PUCCH resource with an SPS setting.
[0061] In some embodiments, the device includes means for determining that the downlink state or joint transmit setting indicator (TCI) state of a physical downlink shared channel (PDSCH) for SPS configuration is associated with a first TAG. In some embodiments, the device includes means for determining that the downlink state or joint transmit setting indicator (TCI) state of a physical downlink control channel (PDCCH) that activates SPS configuration is associated with a core set pool index, wherein one or more uplink TCI states or joint TCI states are activated or indicated for the core set pool index and are associated with the first TAG.
[0062] In some embodiments, the device includes means for releasing an SPS setting based on a determination that the SPS setting is associated with a first TAG. In some embodiments, the device includes means for suspending an SPS setting based on a determination that the SPS setting is associated with a first TAG until a PUCCH resource for the SPS is reconfigured for a TAG having a valid timing advance (TA).
[0063] In some embodiments, the device includes means for suspending an SPS setting until the first TAT recovers, based on a determination that the SPS setting is associated with a first TAG. In some embodiments, the device includes means for releasing a suspended SPS setting, based on a determination that both the first TAT and the second TAT are in a first state. In some embodiments, the device includes means for deactivating an SPS setting, based on a determination that the SPS setting is associated with a first TAG.
[0064] In some other embodiments, the device includes means for activating the SPS configuration based on an activation command. In some other embodiments, the device includes means for releasing Hybrid Automatic Retransmission Request (HARQ) feedback based on the release of the SPS configuration. In some other embodiments, the device includes means for terminal devices or network devices.

In some embodiments, the means comprises at least one processor and at least one memory containing computer program code, the at least one memory and the computer program code together with the at least one processor being configured to extract performance from the apparatus.
