Technical Field

[0003]

[0004] The following relates generally to wireless communications, and more particularly to techniques for relaxing timeslot format determination. Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each of which simultaneously supports communication for multiple communication devices (which may also be referred to as user equipment (UE)). Summary of the Invention

[0005] The described techniques relate to improved methods, systems, devices, and apparatus that support techniques for relaxing slot format determination. Generally, the described techniques enable a user equipment (UE) to perform a dynamic process for determining a slot format, wherein the UE may determine and apply a configured slot format after a time delay or for a configured duration. For example, the UE may receive a dynamic indication of a time delay or duration for updating a slot format configuration for a slot (e.g., a slot comprising one or more flexible symbol periods). Specifically, the UE may receive a dynamic indication of a slot format from a base station (e.g., via downlink control information (DCI)), and may determine the slot format based on the dynamic indication and the time delay or duration. Determination of the slot format may include the UE waiting for a time delay before determining the format of the slot. Additionally or alternatively, the UE may determine the format of one or more slots for a configured duration, wherein the UE may not monitor for further indications of the slot format until the duration expires. The UE may communicate with the base station according to the time slot format of the determined time slot (eg, within the duration or after a time delay), which may result in reduced UE processing complexity and power consumption, among other benefits.

[0070] In some wireless communication systems, a base station may indicate a timeslot configuration to a user equipment (UE). The timeslot configuration may be indicated via radio resource control (RRC) signaling (e.g., cell-specific RRC signaling, UE-specific RRC signaling), or may be indicated via a slot format indicator (SFI) included in downlink control information (DCI), or both. These indications may provide a timeslot format for each of a plurality of timeslots used for communication with the base station, where each timeslot may be used for uplink (e.g., having a plurality of symbol periods configured for uplink transmission), downlink (e.g., having a plurality of symbol periods configured for downlink reception), or may be flexible (e.g., having one or more symbol periods that may be configured for uplink or downlink).

[0071] In some cases, the UE may determine an updated slot format for a flexible slot based on RRC signaling, a DCI indication, or a combination thereof. When determining the slot format, the UE may overwrite the flexible symbols in the flexible slot provided by the previously received slot format configuration. As an example, the UE may identify an RRC-configured flexible slot format (e.g., configured by cell-specific or UE-specific RRC signaling) and then jointly determine the slot format for the flexible slot using a dynamically indicated SFI. However, the process for dynamically determining the slot format (e.g., based on the SFI received within the DCI) may be complex and may be difficult for the UE to implement due to increased processing at the UE (e.g., due to dynamically switching radio frequency (RF) components between uplink and downlink, or vice versa). Specifically, the UE may immediately determine and apply the indicated slot format upon receiving the slot format indication, which may result in latency in the system and increased power consumption when the UE processes the slot format configuration. In addition, the UE may continuously monitor one or more different slot format configurations provided by different types of signaling. Therefore, the process for determining the slot format based on the received indication may result in relatively high UE processing complexity (e.g., due to how quickly the UE can determine the slot format), which may lead to delays, inefficient communications, and increased power consumption. The complexity of determining the slot format may be particularly significant in cases where the UE is a low-complexity or low-power UE (e.g., with limited processing capabilities). Therefore, it is desirable to utilize techniques that relax the process of determining the slot format by the UE.

[0072] Thus, the techniques described herein may enable a UE to perform dynamic determination of a slot format using a relaxed slot format determination process, which may allow the UE to reduce the complexity associated with flexible slot format determination, thereby improving power consumption and latency in the system by reducing the processing burden on the UE. Various aspects of the present disclosure provide that, upon receiving a dynamic indication (e.g., in a DCI), the UE uses a time parameter when determining a slot format configuration for one or more flexible slots. In some cases, the UE may wait for a period of time before determining the slot format configuration and applying it to the slot. For example, the UE may determine a time delay based on a configured determination timeline (e.g., indicated in a DCI or UE-specific RRC signaling). When the UE receives a dynamic indication of a slot format configuration, the UE may wait until the configured timeline (e.g., time delay) before starting to configure the slot according to the dynamic indication. The time delay may be specified in the indication to the UE for determining the slot format (e.g., a received DCI including an SFI), in the indication received in RRC signaling, and may be a predetermined value or may be determined by the UE. In some cases, the UE may determine a slot format for a single time slot that occurs later in the timeline. In some other cases, the UE may repeat the determined slot format in another time slot until a subsequent indication is received or a specified repetition period is reached. This time delay may allow the UE to wait for a period of time before applying the slot format configuration to a time slot (e.g., a flexible time slot), thereby reducing processing complexity at the UE due to the increased time frame (e.g., compared to applying the slot format configuration to the time slot immediately after receiving a dynamic indication).

[0073] Additionally or alternatively, the UE may determine the slot format for the configured duration after receiving the dynamic indication. For example, the UE may determine the slot format for multiple different time slots occurring within the configured duration. The UE may receive an indication of the slot format that may be applied to the upcoming symbol (e.g., an indication carried by DCI format 2_0, an indication in UE-specific RRC signaling, or both), and then identify a duration associated with the process for determining the slot format. The duration may begin upon receiving the dynamic indication of the slot format configuration, and the UE may apply the slot format configuration to one or more time slots occurring within the duration. In some examples, the UE may apply the configuration to a threshold number of time slots (e.g., one or two time slots) within the duration (e.g., based on an indication, a predetermined value, or characteristics of the UE). In some other examples, the UE may apply the slot format configuration to time slots within the duration and then repeat the same configuration in other time slots (e.g., flexible time slots) until the duration expires, until another dynamic indication is received, a configured or predetermined number of repetitions is reached, or any combination thereof. In some aspects, the UE may avoid monitoring for additional dynamic indications of the slot format configuration (eg, sent in a DCI) for a configured duration, which may ease processing at the UE (eg, reduce processing overhead).

[0074] In some examples, the UE may use the time delay or duration described herein to selectively determine the format of one or more time slots, which may be based on the communication direction or signaling type or both. For example, the UE may receive an indication of the time slot format of the downlink configuration and may wait until after the time delay to apply the downlink configuration to the flexible time slot, while the time slot format of the uplink configuration may be applied to the flexible time slot immediately upon receiving the corresponding indication. In some other examples, the use of the time delay or duration may be based on the priority of the channel type or signaling to be used when updating the time slot format. Additionally or alternatively, the UE may update a portion of the flexible time slot upon receiving an indication of the time slot format configuration, for example, where the last symbol in time of the flexible time slot may be updated to have an uplink format (which may allow the UE time to switch between downlink and uplink). In some cases, the UE may report to the base station which technologies for determining the time slot format are supported based on explicit reporting, UE type, UE mode, or a combination thereof.

[0075] Aspects of the present disclosure are initially described in the context of wireless communication systems. Additional aspects of the present disclosure are described with reference to time slot diagrams and process flows. Aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow charts related to techniques for relaxing time slot format determination.

The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an improved LTE (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, communication with low-cost and low-complexity devices, or any combination thereof. In some examples, the wireless communication system 100 may support relaxation of the time slot format determination process, which may provide efficient communication with enhanced reliability and reduced processing complexity.

[0077] Base stations 105 may be dispersed throughout a geographic area to form wireless communication system 100 and may be devices of different forms or with different capabilities. Base stations 105 and UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which a UE 115 and base station 105 may establish one or more communication links 125.

The UEs 115 described herein may be capable of communicating with various types of devices such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relays, integrated access and backhaul (IAB) nodes, or other network devices). Figure 1 As shown in .

[0079] Base stations 105 can communicate with core network 130, or with each other, or both. For example, base stations 105 can interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base stations 105 can communicate with each other via backhaul links 120 (e.g., via X2, Xn, or other interfaces) directly (e.g., directly between base stations 105) or indirectly (e.g., via core network 130), or both. In some examples, backhaul links 120 can be or include one or more wireless links.

In some examples, UE 115 may be an example of a low-power device, a low-end device, or an example of a device that supports limited functionality. For example, UE 115 may have a small form factor design, may be configured with limited processing capabilities (e.g., based on components of UE 115), or both. Thus, such UE 115 may benefit from operations and processing with reduced complexity. In some other cases, UE 115 that is not limited in functionality and processing capabilities, for example, may benefit from less complex processing through power savings and increased communication reliability. In any case, the described techniques may provide one or more advantages for various types of UE 115.

[0082] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network devices including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples. Figure 1 As shown in .

[0083] The UE 115 and the base station 105 can communicate wirelessly with each other via one or more communication links 125 over one or more carriers. The term "carrier" can refer to a set of RF spectrum resources with a defined physical layer structure to support the communication link 125. For example, a carrier used for the communication link 125 can include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel can carry acquisition signaling (e.g., synchronization signals, system information), control signaling to coordinate the operation of the carrier, user data, or other signaling. The wireless communication system 100 can use carrier aggregation or multi-carrier operation to support communication with the UE 115. Depending on the carrier aggregation configuration, the UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used with frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0084] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in FDD mode) or may be configured to carry both downlink and uplink communications (e.g., in TDD mode).

[0085] A carrier can be associated with a particular bandwidth of the RF spectrum, and in some examples, the carrier bandwidth can be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth can be one of a plurality of determined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). The devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) can have a hardware configuration that supports communication on a particular carrier bandwidth, or can be configurable to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 can include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 can be configured to operate on a portion (e.g., subband, BWP) or all of the carrier bandwidth.

[0086] The signal waveform transmitted via the carrier may be composed of multiple subcarriers (e.g., using a multicarrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may comprise one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements a UE 115 receives and the higher the order of the modulation scheme, the higher the data rate for the UE 115 may be. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers may further increase the data rate or data integrity for communications with the UE 115.

[0087] Multiples of the basic time unit can be used (for example, it can be referred to as T s =1 / (Δf max ·N f ) seconds) to represent the time interval for the base station 105 or the UE 115, where Δf max It can indicate the maximum supported subcarrier spacing, N f The maximum supported discrete Fourier transform (DFT) size may be indicated. Time intervals of communication resources may be organized according to radio frames, where each radio frame has a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0088] Each frame can include multiple consecutively numbered subframes or time slots, and each subframe or time slot can have the same duration. In some examples, the frame can be divided (e.g., in the time domain) into subframes, and each subframe can be further divided into multiple time slots. Alternatively, each frame can include a variable number of time slots, and the number of time slots can depend on the subcarrier spacing. Each time slot can include multiple symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, the time slots can be further divided into multiple micro-time slots containing one or more symbols. In addition to the cyclic prefix, each symbol period can contain one or more (e.g., N f ) sampling period. The duration of a symbol period may depend on the subcarrier spacing or the operating band.

[0089] A subframe, slot, mini-slot, or symbol may be the minimum scheduling unit (e.g., in the time domain) of the wireless communication system 100, and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the minimum scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0090] Physical channels may be multiplexed onto a carrier according to various techniques. For example, physical control channels and physical data channels may be multiplexed onto a downlink carrier using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by multiple symbol periods and may extend across a system bandwidth or a subset of the system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more of UEs 115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates having one or more aggregation levels arranged in a cascaded manner. The aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the encoded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0091] Each base station 105 can provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" can refer to a logical communication entity used for communication with the base station 105 (e.g., via a carrier), and can be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), etc.) used to distinguish adjacent cells. In some examples, a cell can also refer to a geographic coverage area 110 or a portion (e.g., a sector) of the geographic coverage area 110 on which the logical communication entity operates. Depending on various factors (such as the capabilities of the base station 105), such a cell can range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell can be or include a building, a subset of a building, or the external space between or overlapping the geographic coverage area 110, as well as other examples.

[0092] A macro cell typically covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs 115 that have a service subscription with a network provider that supports the macro cell. Small cells may be associated with lower-power base stations 105 than macro cells, and small cells may operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. A small cell may provide unrestricted access to UEs 115 that have a service subscription with a network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a residence or office). A base station 105 may support one or more cells and may also support communications over one or more cells using one or more component carriers.

[0093] In some examples, base stations 105 can be mobile and, therefore, provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, but the different geographic coverage areas 110 can be supported by the same base station 105. In some other examples, overlapping geographic coverage areas 110 associated with different technologies can be supported by different base stations 105. For example, wireless communication system 100 can include a heterogeneous network in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.

[0094] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, the base stations 105 can have similar frame timing, and transmissions from different base stations 105 are approximately aligned in time. For asynchronous operation, the base stations 105 can have different frame timing, and in some examples, transmissions from different base stations 105 may not be aligned in time. The techniques described herein can be used for either synchronous or asynchronous operation.

[0095] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technologies that allow devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communication from devices that incorporate sensors or meters, where the sensors or meters measure or capture information and relay such information to a central server or application, which utilizes the information or presents it to a person interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based service billing. In one aspect, the techniques disclosed herein may be applicable to MTC or IoT UEs 115. MTC or IoT UE 115 may include MTC / enhanced MTC (eMTC, also known as Category (Cat)-M, Cat M1) UE 115, NB-IoT (also known as CAT NB1) UE 115, and other types of UE 115. eMTC and NB-IoT may refer to future technologies that may evolve from or be based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (enhanced further eMTC), or mMTC (massive MTC), and NB-IoT may include eNB-IoT (enhanced NB-IoT) or FeNB-IoT (further enhanced NB-IoT).

[0096] Some UEs 115 may be configured to employ a mode of operation that reduces power consumption, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but does not support simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for the UE 115 include entering a power-saving deep sleep mode when not engaged in active communications, operating over a limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, the UE 115 may be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside of a carrier.

[0097] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency or critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private communication or group communication and can be supported by one or more mission-critical services such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions can include prioritization of services, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency can be used interchangeably herein.

[0098] In some examples, UE 115 may also be able to communicate directly with other UEs 115 via device-to-device (D2D) communication links 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 using D2D communication may be located within the geographic coverage area 110 of base station 105. Other UEs 115 in such a group may be located outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, a group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system in which each UE 115 transmits to each other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In some other cases, D2D communication is performed between UEs 115 without the involvement of base station 105.

[0099] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) that manages access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) that routes packets or interconnects to external networks. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UEs 115 served by base stations 105 associated with the core network 130. User IP packets may be transmitted through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the network operator IP service 150. Operator IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0100] Some of the network devices (such as base stations 105) may include subcomponents such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with the UE 115 through one or more other access network transport entities 145 (which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs)). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or consolidated into a single network device (e.g., base station 105).

[0101] The wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). The region from 300 MHz to 3 GHz is often referred to as the very high frequency (UHF) region or decimeter band, as its wavelengths range from approximately one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features, but they can penetrate structures sufficiently for a macrocell to provide service to a UE 115 located indoors. Transmissions using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to transmissions using the smaller frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0102] The wireless communication system 100 may also operate in the super high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz, which is also referred to as the centimeter band, or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz), which is also referred to as the millimeter band. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices may be smaller and more compact than the UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and shorter distances than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may differ by country or regulatory body.

[0103] The wireless communication system 100 can utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed RF spectrum band, devices such as the base station 105 and the UE 115 can employ carrier sensing for conflict detection and avoidance. In some examples, operations in the unlicensed band can be based on a carrier aggregation configuration (e.g., LAA) in combination with component carriers operating in a licensed band. Operations in the unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.

[0104] The base station 105 or UE 115 may be equipped with multiple antennas that can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located in one or more antenna arrays or antenna panels that can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, the antennas or antenna arrays associated with the base station 105 may be located in different geographical locations. The base station 105 may have an antenna array with multiple rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panels may support RF beamforming for signals transmitted via the antenna ports.

[0105] The base station 105 or UE 115 can use MIMO communication to exploit multipath signal propagation and increase spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technology may be referred to as spatial multiplexing. For example, a transmitting device may send multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) and multi-user MIMO (MU-MIMO), where under SU-MIMO, multiple spatial layers are sent to the same receiving device, and under MU-MIMO, multiple spatial layers are sent to multiple devices.

[0106] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or receiving device (e.g., base station 105, UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array so that some signals propagating according to a particular orientation with respect to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals transmitted via antenna elements can include the transmitting device or receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of the antenna elements can be defined by a set of beamforming weights associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation).

[0107] The base station 105 or the UE 115 can use beam sweeping techniques as part of a beamforming operation. For example, the base station 105 can use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. The base station 105 can transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, the base station 105 can transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions can be used to identify (e.g., by a transmitting device such as the base station 105 or a receiving device such as the UE 115) a beam direction for later transmission or reception by the base station 105.

[0108] Base station 105 may transmit some signals (such as data signals associated with a particular receiving device) along a single beam direction (e.g., a direction associated with a receiving device such as UE 115). In some examples, the beam direction associated with the transmission along the single beam direction may be determined based on signals transmitted along one or more beam directions. For example, UE 115 may receive one or more of the signals transmitted by base station 105 along different directions and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or another acceptable signal quality.

[0109] In some examples, transmissions by a device (e.g., base station 105 or UE 115) can be performed using multiple beam directions, and the device can use a combination of digital precoding or RF beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 can report feedback indicating precoding weights used for one or more beam directions, and the feedback can correspond to a configured number of beams across the system bandwidth or one or more subbands. Base station 105 can send reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)), which can be precoded or unprecoded. UE 115 can provide feedback for beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals sent by base station 105 in one or more directions, UE 115 may employ similar techniques to send signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115) or to send signals in a single direction (e.g., to send data to a receiving device).

[0110] When receiving various signals from the base station 105 (such as synchronization signals, reference signals, beam selection signals, or other control signals), the receiving device (e.g., UE 115) can try multiple reception configurations (e.g., directional listening). For example, the receiving device can try multiple reception directions by receiving via different antenna subarrays, processing the received signal according to different antenna subarrays, receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) (where these weight sets are applied to signals received at multiple antenna elements of the antenna array), or processing the received signal according to different receive beamforming weight sets (where these weight sets are applied to signals received at multiple antenna elements of the antenna array), any of which can be referred to as "listening" according to different reception configurations or reception directions. In some examples, the receiving device can use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned on a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0111] The wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication at the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly to communicate through logical channels. The medium access control (MAC) layer can perform priority processing and multiplexing of logical channels to transport channels. The MAC layer can also use error detection technology, error correction technology, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the RRC protocol layer can provide the establishment, configuration, and maintenance of an RRC connection between the UE 115 and the base station 105 or the core network 130 that supports radio bearers for user plane data. At the physical layer, transport channels can be mapped to physical channels.

[0112] UE 115 and base station 105 can support retransmission of data to increase the likelihood of successfully receiving the data. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data over communication link 125. HARQ can include a combination of error correction (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device can support same-slot HARQ feedback, wherein the device can provide HARQ feedback in a particular time slot for data received in a previous symbol of the time slot. In some other cases, the device can provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0113] The wireless communication system 100 may support a time slot determination process using a relaxed time frame. For example, the base station 105 may send an indication of a time parameter associated with determining a configuration for a time slot duration. The time parameter may be a time delay or a configured duration, wherein the UE 115 may apply the time delay or duration to the time slot determination process. Specifically, the UE 115 may identify the time parameter and then receive an indication of the time slot configuration from the base station 105 (e.g., a dynamic or semi-static indication of a time slot format configuration). The UE 115 may determine the configuration or format of one or more time slot durations based on the received indication and in accordance with the time parameter. In one example, the UE 115 may wait for a period of time equal to the time delay before applying the received time slot configuration to subsequent time slots, which may introduce a delay between the time when the time slot configuration is received and the time when the UE 115 applies the indicated time slot configuration, thereby reducing the processing time for time slot format determination (e.g., compared to if the UE 115 immediately determined or applied the time slot configuration upon receiving the indication). In another example, UE 115 can apply the slot format configuration for a configured duration, wherein UE 115 can avoid monitoring other indications of the slot format configuration during the configured duration. Here, the duration can enable UE 115 to determine the slot format when receiving the indicated slot format, but can also relax the monitoring and processing performed by UE 115 (e.g., compared to continuously monitoring the slot format configuration). In some examples, the slot format configuration can be applied to one slot or can be repeated across multiple slots. Then, base station 105 and UE 115 can communicate during one or more slot durations based on the slot configuration and using time parameters.

[0114] Figure 2An example of a wireless communication system 200 that supports techniques for relaxing slot format determination according to aspects of the present disclosure is shown. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100 and can include a UE 115-a and a base station 105-a, which can be referenced. Figure 1 1 and 2. As described herein, the UE 115 and base station 105 may transmit and receive control information and data via the communication link 125-a on symbols in a time slot 205 (e.g., a time slot duration), which may be based on the number of symbols in the time slot 205 and the format of the time slot 205. The UE 115-a and base station 105-a may transmit and receive data on multiple symbols in one or more time slots 205 during a communication duration 210. Each time slot 205 may have a time slot format and a time slot duration. In some cases, the time slot format may determine a transmission direction for each of one or more symbols within the time slot 205, which may include uplink symbols, downlink symbols, and flexible symbols that may be flexibly and dynamically configured for uplink or downlink communication.

[0115] In some cases, the network (e.g., base station 105-a) may select a time slot format or time slot configuration from a plurality of time slot formats (e.g., 61 time slot formats) and indicate the selection to UE 115-a. Base station 105-a and UE 115-a may use each time slot 205 for uplink communication or downlink communication. Thus, each time slot 205 may be an uplink time slot 205, a downlink time slot 205, or may remain flexible (e.g., may be used to send uplink or downlink symbols). In some cases, the indication of the time slot configuration may include a combination of RRC parameters and a DCI format (e.g., DCI format 2_0). For example, UE 115-a may receive an RRC configuration, a DCI indication, or both for each time slot 205 from base station 105-a. UE 115-a may then determine the time slot configuration (e.g., uplink or downlink direction or whether the time slot 205 is flexible) based on the RRC configuration, the DCI indication, or both.

[0116] In some examples, the RRC configuration may include several RRC parameters, which may correspond to a cell-specific slot format configuration or a UE-specific slot format configuration. For example, a cell-specific RRC slot format configuration (e.g., tdd-UL-DL-ConfigurationCommon) may provide a slot format for each of the plurality of slots 205 (e.g., the slots 205 during the communication duration 210). The configuration may provide one or more patterns for the time slots 205, each pattern having a number of parameters including, but not limited to, the periodicity of the uplink-downlink pattern (e.g., dl-Ul-TransmissionPeriodicity), the number of consecutive complete downlink time slots 205 at the beginning of each downlink-uplink pattern (e.g., nrofDownlinkSlots), the number of consecutive downlink symbols at the beginning of the time slot 205 after the last complete downlink time slot 205 (e.g., nrofDownlinkSymbols), the number of consecutive complete uplink time slots 205 at the end of each uplink-downlink pattern (e.g., nrofUplinkSlots), and the number of consecutive uplink symbols at the end of the time slot 205 before the first complete uplink time slot 205 (e.g., nrofUplinkSymbols). In some cases, unassigned time slots 205 and symbols after the last downlink symbol and before the first uplink symbol may be designated as flexible time slots 205 and symbols.

[0117] In some other examples, the RRC configuration may include a UE-specific slot format configuration (e.g., tdd-UL-DL-ConfigurationDedicated), and the UE 115-a may use the configuration to override the flexible symbols in the time slot 205. For example, the UE 115-a may receive a UE-specific RRC slot format configuration that may include additional information about the time slot 205 provided by the RRC slot format configuration. In some cases, the UE-specific slot format configuration may include a set of slot configurations for a set of time slots 215 (e.g., slot configurations that may include one or more flexible symbols, such as those corresponding to the set of time slots 215) and associated slot indices. The UE 115-a may override the cell-specific slot format configuration for the time slot 205 corresponding to the associated slot index. For example, the UE 115-a may override the flexible symbols in the set of time slots 215 as uplink symbols or downlink symbols according to the UE-specific slot format configuration.

[0118] In addition, the UE 115 may determine a slot format or slot configuration based on a DCI indication. For example, the UE 115-a may receive an SFI (e.g., DCI format 2_0) included in the DCI from the base station 105-a. In some cases, the SFI in the DCI may be scrambled using an SFI radio network temporary identifier (SFI-RNTI). The DCI may indicate a slot format for each slot 205 in the communication duration 210. In some cases, the slot format indication may start from the slot 205 in which the UE 115 detected the DCI. For example, the UE 115-a may jointly determine the slot format using an RRC-configured slot format for the slot 205 (e.g., a cell-specific and UE-specific RRC-configured slot format) and the SFI for the slot 205. In some cases, the UE 115-a may support the RRC-configured slot format configuration and may choose to support the SFI included in the DCI, which may be signaled via a capability report for the UE 115-a. In some cases, the process by which UE 115-a may determine a slot format based on an SFI received within a DCI may be referred to as dynamic determination of a slot format. That is, the dynamic determination (or dynamic determination process) may correspond to UE 115-a determining a slot format for flexible slots 205 (which may have been previously configured, e.g., via RRC signaling), based on a dynamic indication of the slot format received (e.g., in a DCI).

[0119] In some cases, the dynamic determination of the time slot format may be a complex process for UE 115-a to implement. For example, it may be difficult for UE 115-a to dynamically switch the RF chain between the uplink and downlink for different time slots 205 or symbols within a time slot 205. For example, UE 115-a may receive an SFI within a DCI that dynamically indicates the time slot format, and it may be expected that UE 115-a applies the indicated time slot format without delay (e.g., to the flexible time slot immediately after receiving the DCI). In some other examples, UE 115-a may receive dynamic scheduling information for uplink and downlink data and signals. The dynamic scheduling information may allow UE 115-a to override the RRC configured time slot format. In such a case, the dynamic determination of the time slot format may depend on UE 115-a being ready to dynamically determine the communication direction and communicate (e.g., reception or transmission of data and signals in a time slot). For example, UE 115-a may, after receiving a DCI, use dynamic scheduling to specify uplink or downlink communications in flexible symbols (e.g., for a set of time slots 215). Additionally, UE 115-a may, after receiving a DCI for downlink reception or uplink transmission, use dynamic scheduling to cancel a higher-layer configured uplink transmission or downlink reception. In some cases, the higher-layer configured uplink transmission or downlink reception may be in the flexible symbols indicated by the SFI in the DCI. In such cases, the dynamic override or cancellation operation may result in a relatively high processing complexity for UE 115. Therefore, it may be beneficial to relax the dynamic timeslot format determination process for UE 115.

[0120] As described herein, the wireless communication system 200 may support the use of techniques that relax the dynamic determination of time slot formats. More specifically, the described techniques may enable a UE 115-a to perform dynamic determination of time slot formats using a relaxed dynamic determination process, which may allow the UE 115-a to reduce the complexity associated with the time slot format determination, thereby improving power consumption and latency in the system by reducing the processing burden on the UE 115-a. In some cases, when a dynamic indication is received (e.g., in a DCI), the UE 115-a may use a time parameter when determining a time slot format configuration for one or more flexible time slots 205. In some cases, the UE 115-a may wait for a period of time before determining the time slot format configuration and applying it to the time slots 205. For example, the UE 115-a may determine the time delay based on a configured determination timeline (e.g., indicated in a DCI, in UE-specific RRC signaling (such as contained in a parameter Tdd-UL-DL_ConfigurationDedicated, or other signaling). When the UE 115-a receives a DCI indicating a slot format configuration, the UE 115-a may wait until after the configured timeline (e.g., the time delay) before starting to configure one or more time slots 205 according to the dynamic indication. The time delay may be specified in an indication to the UE 115-a for determining the slot format (e.g., a received DCI including an SFI), in an indication received in RRC signaling, may be a predetermined value, or may be determined by the UE 115-a. In some cases, the UE 115-a may determine the slot format for a single time slot 205 occurring after the timeline. In some other cases, the UE 115-a may determine the slot format for a single time slot 205 occurring after the timeline. 115-a may repeat the determined slot format in one or more additional time slots 205 until a subsequent indication is received or a specified repetition period is reached. Here, the determination of the slot format for the one or more time slots 205 may be based on a corresponding pattern, which may be indicated to the UE 115-a by the base station 105-a (e.g., in RRC signaling, in DCI). This time delay may enable the UE 115-a to wait for a period of time before applying the slot format configuration to the time slot 205 (e.g., the flexible time slot 205), which reduces processing complexity at the UE 115-a due to the increased time frame (e.g., compared to applying the slot format configuration to the time slot 205 immediately after receiving the DCI message).

[0121] Additionally or alternatively, the UE 115-a may determine a slot format for a configured duration after receiving a DCI message. For example, the UE 115-a may determine a slot format for a plurality of different time slots 205 occurring within the configured duration. The UE 115-a may receive an indication of a slot format that may be applied to an upcoming time slot 205 (e.g., an indication carried by DCI format 2_0, an indication in UE-specific RRC signaling, or both), and then identify a configured duration associated with a process for determining the slot format. The duration may begin upon receipt of the DCI indicating a slot format configuration, and the UE 115-a may apply the slot format configuration to one or more time slots 205 occurring within the duration. In one example, the UE 115-a may apply the configuration to a single time slot 205 within the duration (e.g., based on an indication, a predetermined value, or a characteristic of the UE 115-a). In some other examples, UE 115-a may apply the slot format configuration to the first slot 205 within the duration and may then repeat the same configuration in other slots 205 (e.g., other flexible slots 205 occurring within the configured duration) until the duration expires, until another DCI is received, a configured or predetermined number of repetitions is reached, or any combination thereof. In some cases, UE 115-a may avoid monitoring for additional DCI indicating the slot format configuration while the configured duration is in effect, which may ease processing at UE 115-a.

[0122] In some examples, UE 115-a may use a time delay or duration to selectively determine the format of one or more symbols of time slot 205, which may be based on the communication direction, signaling type, signal priority, or other parameters. For example, UE 115-a may receive a DCI including an indication of a time slot format for a downlink configuration and may wait until after a time delay to apply the downlink configuration to the flexible time slot 205, while the time slot format for the uplink configuration may be applied to the flexible time slot 205 immediately upon receiving the corresponding DCI. In such a case, the use of a delay (or duration) may be based on the communication direction of the time slot format. In some other examples, the use of a time delay or duration may be based on the channel type or signaling priority to be used when updating the time slot format. Additionally or alternatively, UE 115-a may update a portion of the flexible time slot 205 upon receiving the DCI, for example, where the last symbol period in time of the flexible time slot 205 may be updated to have the uplink format (which may allow UE 115-a to switch between downlink and uplink at any time). In some cases, UE 115-a may send a report to base station 105-a that includes techniques for determining supported slot formats based on explicit reporting, UE type, UE mode, or a combination thereof. In such cases, base station 105-a may identify how UE 115-a may determine the slot format, which may be based on an indicated capability of UE 115-a, based on a known operating mode of UE 115-a, or based on explicit signaling from UE 115-a.

[0123] UE 115-a may determine to implement a partial dynamic determination, wherein some types of slot formats may be applied upon reception and other types of slot formats may be applied based on a time delay or duration. In some cases, UE 115-a may perform a dynamic determination based on the type of transmission. For example, a dynamic determination that may be applied without delay may trigger an uplink slot format, which may improve downlink reception complexity at UE 115-a. More specifically, a dynamically indicated slot format corresponding to a downlink slot format for a flexible slot 205 may be applied based on a duration or delay. A slot format corresponding to an uplink slot format for a flexible slot 205 may be applied upon receipt of a dynamic indication. Because there may be a large number of downlink slot formats dynamically configured for UE 115-a, the use of a time delay or duration for the downlink may reduce the complexity of the dynamic determination process while allowing uplink transmissions to be configured without delay in subsequent slots 205, thereby reducing complexity while reducing latency. A similar process may be implemented, where the downlink slot format is applied upon receipt, while the uplink slot format is applied after a delay or for a configured duration.

[0124] In some cases, UE 115-a may perform a dynamic determination process based on a time delay or duration, a channel type, a signal scheduled for transmission, or a combination thereof. For example, in the case where a reference signal (e.g., for measurement) is scheduled for transmission or reception during time slot 205, when a dynamic indication is received, the corresponding time slot format for transmission of such reference signal may be immediately applied or updated. However, for time slots 205, symbols, or both in which data for a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), or a downlink data channel is transmitted, UE 115-a may use a time delay or duration. In this way, data transmissions with a relatively high priority (e.g., information sent via PDSCH and PUSCH) may be transmitted during time slots that have been configured using a relaxed time frame, which may enhance the reliability of these channels. In some other cases, based on the type of data to be transmitted during time slot 205, UE 115-a may implement a time delay or duration based on the data type.

[0125] In some cases, UE 115-a may perform a dynamic determination process for a portion of the flexible symbols within slot 205, where a different slot format may be applied to the symbols based on a dynamic indication (e.g., received in a DCI). As an example, UE 115-a may apply an updated slot format to a portion of the symbols within the slot upon receiving a dynamic indication of the slot format. Here, the slot format may indicate an uplink configuration for a portion of a plurality of symbols, and the symbols may be the last one or more flexible symbols in a flexible slot (e.g., a slot after the dynamic indication is received). The unused portion of the unconfigured slot (e.g., symbols before the last flexible symbol) may result in a delay caused by dynamically switching the RF chain between the uplink and downlink, thereby leaving sufficient time for UE 115-a to decode the corresponding DCI and switch the transceiver from downlink to uplink.

[0126] In some cases, the UE 115-a may report to the base station 105-a which methods for dynamic determination the UE 115-a supports. For example, the UE 115-a may report to the base station 105-a via uplink signaling (e.g., a UE capability report) which techniques the UE 115-a supports for the dynamic determination process (e.g., using a time delay, using a duration, or both). In some cases, the UE 115-a may report its UE type (e.g., a reduced complexity UE type), and the base station 105-a may determine which time slot format determination techniques the UE 115-a supports based on the reported UE type. In some other cases, the UE 115-a may operate in a certain UE mode (e.g., a low power mode, a low-end mode, or other mode), and the corresponding dynamic determination technique may be based on the UE mode of the UE 115-a (which may be determined by the base station 105-a).

[0127] Figure 3A and 3B Examples of time slot diagrams 300 and 305 supporting techniques for relaxing time slot format determination according to aspects of the present disclosure are shown. In some examples, the time slot diagrams 300 and 305 can implement aspects of the wireless communication system 100, the wireless communication system 200, or both. For example, the time slot diagrams 300 and 305 can each illustrate a time frame in which the UE 115 updates or applies an indicated time slot format to one or more symbols in a flexible time slot based on a configured delay. The time slot diagrams 300 and 305 include time slots 310, which can be as described with reference to FIG. Figure 2 A corresponding example of time slot 205 is described.

[0128] In some cases, the UE 115 may identify the time delay (e.g., determine the timeline 320) based on an indication from the base station 105, a predetermined value, or a UE configuration. The indication of the determine timeline 320 may be received in RRC signaling, in a DCI message, or a combination thereof. The determine timeline 320 may include multiple time slots 310. For example, Figure 3A and Figure 3B , the configured determination timeline 320-a and determination timeline 320-b may include five time slots 310. Although five time slots 310 are used in the described example of determination timeline 320, any number of time slots 310 or other duration (e.g., in units of time) may be used for determination timeline 320.

[0129] UE 115 may receive a dynamic timeslot configuration indication (e.g., an indication of dynamic determination 325 sent in a DCI) from base station 105. For example, Figure 3A As shown in , time slot 310-a may be the last downlink time slot 310 according to the indicated RRC cell-specific time slot format configuration, and UE 115 may receive an indication of dynamic determination 325-a during downlink time slot 310-a. The indication of dynamic determination 325-a may include an RRC configuration, a DCI indication (e.g., an SFI included in DCI format 2_0), or both. The last downlink symbol in downlink time slot 310-a may be followed by one or more flexible time slots 310, uplink time slot 310, or both. For example, flexible time slot 310-b may immediately follow downlink time slot 310-a. However, instead of applying the indicated time slot format (e.g., received via the indication of dynamic determination 325-a) to flexible time slot 310-b, UE 115 may wait until after the determination timeline 320 (e.g., a time delay) before applying the indicated time slot format to the flexible time slot 310. Specifically, after waiting for the determination timeline 320-a, UE115 can apply the updated time slot format 330-a to the flexible time slot 310-c, where the updated time slot format 330-a can update the configuration of the previously configured flexible symbols of the time slot 310-c to one or more uplink symbols, downlink symbols, flexible symbols or a combination thereof according to a dynamic determination process.

[0130] Similarly, if Figure 3BAs shown in , UE 115 may receive an indication of dynamic determination 325-b in one or more symbols of downlink time slot 310-d and then wait for the configured timeline 320-b before implementing the dynamic determination process and applying the updated time slot format 330-b to time slot 310-e (i.e., UE 115 may wait for the time delay to elapse). Here, even if UE 115 receives an indication of dynamic determination 325-a and dynamic determination 325-b during or after downlink time slot 310-a and downlink time slot 310-d, respectively, UE 115 may not perform the dynamic determination process until after determination timeline 320-a and determination timeline 320-b (e.g., updating time slot 310-a and updating time slot 310-c). Thus, upon receiving an indication for dynamic determination 325, UE 115 may wait for a number of time slots 310 (e.g., five time slots 310) or a duration (e.g., using a clock or timer) specified by the configured determination timeline 320, which may relax the time frame for applying the updated time slot format 330 to the flexible symbols of the time slots 310.

[0131] In some cases, such as Figure 3A As shown in , UE 115 may implement a dynamic determination process for time slot 310 according to a first mode. For example, the first mode may be associated with performing a dynamic determination process for a single time slot 310 (e.g., for flexible time slot 310-c). In some other examples, such as Figure 3B As shown in , the second mode can be associated with the UE 115 repeating the dynamic determination process across multiple time slots 310. In this case, the UE 115 can determine an updated time slot format 330-b and apply it to the flexible time slot 310-e, and then apply the repetition of the updated time slot format 330-b to one or more subsequent time slots 310 (e.g., flexible time slot 310-e, flexible time slot 310-f, and flexible time slot 310-g). The dynamic determination process and the repetition of the updated time slot format 330-b can be repeated until the UE 115 receives another indication of the dynamic determination 325, or reaches a specified repetition period, reaches a number of repetitions, or a combination thereof. In some cases, the repetition period can be a predetermined value, specified in the indication of the dynamic determination 325, or specified by other means. In addition, the use of the first mode, the second mode, or a combination thereof can be indicated to the UE 115 by the base station 105 (e.g., in RRC signaling, a DCI message, or both). In some cases, the mode may be indicated in the same or different signaling that indicates the determination timeline 320 to the UE 115 .

[0132] Figure 4A and 4BExamples of slot diagrams 400 and 405 that support the ability to relax slot format determination for a wireless communication system according to aspects of the present disclosure are shown. In some examples, the slot diagrams 400 and 405 can implement aspects of the wireless communication system 100, the wireless communication system 200, or both. For example, the slot diagrams 400 and 405 can each illustrate a time frame in which the UE 115 updates or applies an indicated format to one or more symbols in a flexible time slot based on a configured duration. The slot diagrams 400 and 405 include a time slot 410, which can be as described with reference to FIG. Figure 2 、 3A and 3B . The time slot diagrams 400 and 405 also include an indication of the dynamic determination 425 and the updated time slot formats 430 and 435, which may be referenced. Figure 3A and 3B An indication of dynamic determination 325 and a corresponding example of an updated time slot format 330 are described.

[0133] In some cases, the UE 115 may identify a duration associated with the determined configuration (e.g., the configuration duration 420) based on an indication from the base station 105, a predetermined value, or a capability of the UE 115. The indication of the configuration duration 420 may be received in control signaling such as RRC signaling, in a DCI message, or a combination thereof. The configuration duration 420 may include any number of time slots 410. For example, Figure 4A and Figure 4B , the configuration duration 420-a may include four time slots 410, while the configuration duration 420-b may include five time slots 410. It should be noted that while four and five time slots 410 may be used for the described examples of the configuration duration 420, any number of time slots 410 or other duration (e.g., in units of time) may be used for the configuration duration 420.

[0134] UE 115 may dynamically receive an indication of a timeslot configuration (e.g., an indication of dynamic determination 425) from base station 105, which may be an example of an indication sent in a DCI message during a downlink timeslot 410 (e.g., timeslot 410-a or timeslot 410-f). Figure 4AAs shown in , time slot 410-a may be the last downlink time slot 410 according to the indicated RRC cell-specific time slot format configuration. UE 115 may receive an indication of a dynamic determination 425-a from base station 105 within downlink time slot 410-a. The indication of the dynamic determination 425 may include an RRC configuration, a DCI indication (e.g., DCI format 2_0), or both. The last downlink symbol in downlink time slot 410-a may be followed by one or more flexible time slots, uplink time slots 410, or both (e.g., flexible time slot 410-b and flexible time slot 410-c in addition to one or more uplink time slots 410). UE 115 may perform the dynamic determination process (based on the indication of the dynamic determination 425-a) within the indicated configured duration 420-a. For example, the updated time slot format 430-a configured by the indication of the dynamic determination 425-a may be applied to the flexible time slot 410-b occurring within the configured duration 420-a. In some examples, a threshold number of updated slot formats 430 may be applied to slots 410 during the configuration duration 425. Additionally or alternatively, updated slot formats 430-a may be applied to flexible slots 410-c.

[0135] In some cases, the UE 115 may not monitor for further indications of the dynamic determination 425 during the configuration time frame 420. Specifically, the UE 115 may receive an indication of the dynamic determination 425-a, start a timer or clock for the configuration duration 420-a, apply the updated slot format 430-a to the flexible slot 410-b, and then refrain from monitoring for further indications of the slot format configuration 425 (e.g., sent in a DCI or in RRC signaling). As a result, the UE 115 may relax monitoring, thereby reducing power consumption associated with monitoring signals (e.g., the UE 115 may shut down the RF chain while refraining from monitoring throughout the configuration duration 420-a). However, upon expiration of the configuration duration 420-a, the UE 115 may resume monitoring for further indications of the slot format. Consequently, subsequent or adjacent determinations of the slot format using the further indication of the dynamic determination 425-b may occur after the configuration duration 420-a. In this way, the UE 115 may apply the updated slot format 435-a to the flexible slot 410-d, at which point the UE 115 may optionally use the configured duration 420-a again.

[0136] In the event that the dynamic determination process is based on a threshold, UE 115 may apply a threshold number of updated slot formats 430 (or updated slot formats 435) based on the threshold. For example, if the threshold number of times for applying the slot format during configuration duration 420-a is one (e.g., as indicated by the dynamic determination 425-a), and configuration duration 420-a is four slots, then the number of slots 410 between applying updated slot format 430-a to flexible slot 410-b and applying updated slot format 435-a to flexible slot 410-d may also be four slots. Therefore, if base station 105 attempts to send an additional indication of dynamic determination 425 (e.g., within configuration duration 420-a), UE 115 may not receive the indication of dynamic determination 420 because it is already in the threshold number of dynamic determination processes (e.g., if the threshold is one).

[0137] Similarly, if Figure 4B As shown in FIG, , UE 115 may receive an indication of dynamic determination 425-c and may then perform a dynamic determination process for multiple time slots 410 based on a threshold value for the dynamic determination process for the configured duration 420-b. In particular, rather than applying an updated time slot format 430 to a single time slot 410, UE 115 may repeatedly apply the updated time slot format 430 to multiple time slots 410. For example, the indication of dynamic determination 425-c may correspond to UE 115 applying updated time slot format 430-b at time slot 410-e. UE 115 may then repeat the application of updated time slot format 430-b to flexible time slots 410 (e.g., flexible time slot 410-f and flexible time slot 410-g) within the configured duration 420-b. In some examples, if the base station 105 attempts to send an additional indication of the dynamic determination 420 during the configuration duration 425-b, the UE 115 may not receive the indication until after the configuration duration 420-b (e.g., because the UE 115 may avoid monitoring some downlink transmissions). In some other examples, the UE 115 may receive an additional indication of the dynamic determination 425, but may wait until after the configuration duration 420-b before taking action on the received indication. In some cases, because the base station 105 may be aware that the UE 115 is implementing the configuration duration 420-b, the UE 115 may receive an additional indication of the dynamic determination 420-d at the time slot 410-h after the configuration duration 425-b. The UE 115 may then perform the dynamic determination process by applying the updated time slot format 435-b to the flexible time slot 410-h.

[0138] In some cases, such as Figure 4AAs shown in , UE 115 may perform a dynamic determination process according to a first mode. For example, the first mode may correspond to performing a dynamic determination process for a single time slot 410 (e.g., for a flexible time slot 410-a). In some other examples, such as Figure 4B As shown in , the second mode may correspond to the UE 115 repeating a dynamic determination process, which may correspond to the time slot format provided by the indication of dynamic determination 425-b for one or more time slots 410 according to the second mode (e.g., for flexible time slot 410-e, flexible time slot 410-f, and flexible time slot 410-g). Here, the dynamic determination process may be repeated until the UE 115 receives another indication of dynamic determination at 420-d, or reaches a specified repetition period, or a combination thereof. In some cases, the repetition period may be a predetermined value, specified in the indication of dynamic determination 425, or specified by other means. In addition, the base station 105 may indicate the use of the first mode, the second mode, or a combination thereof to the UE 115 (e.g., in RRC signaling or in a DCI message). In some cases, the mode may be indicated in the same or different signaling as the configuration duration 420 indicated to the UE 115.

[0139] Figure 5 An example of a process flow 500 in a system supporting techniques for relaxing slot format determination according to aspects of the present disclosure is shown. In some examples, the process flow 500 can implement aspects of the wireless communication system 100, the wireless communication system 200, the slot map 300, the slot map 305, the slot map 400, the slot map 405, or a combination thereof. The process flow 500 can include a UE 115-b and a base station 105-b, which can be as described in reference to FIG. Figure 1 and Figure 2 1 and 10. The corresponding examples of the UE 115 and base station 105 are described. In some examples, the UE 115-b can utilize a time delay or duration associated with determining the time slot format to relax the time slot format determination process. Alternative examples of process flow 500 can be implemented in which some processes are performed in a different order than described or not performed. In some cases, the process can include additional functionality not mentioned below, or more processes can be added.

[0140] At 505, UE 115-b may determine the capabilities and send the determined capabilities to base station 105-b in a capabilities message. Base station 105-b may select time parameters (e.g., time delay or duration) that UE 115-b supports based on the capabilities message. In some cases, UE 115-b may send a UE type or mode in addition to or in lieu of the capabilities message. For example, UE 115-b may have a reduced complexity type or may operate based on a low power or low-end mode. In this way, base station 105-b may determine the time parameters based on the UE type or mode.

[0141] At 510, the base station 105-b may send an indication of a time parameter to the UE 115-b. The indication of the time parameter may include an RRC control message (e.g., UE-specific signaling), an SFI included in the DCI (e.g., where the DCI is DCI format 2_0), or a combination thereof. In some cases, the base station 105-b may send the indication of the time parameter based on a capability message from the UE 115-b. For example, the capability message may indicate that the UE 115-b supports a time delay time parameter, and thus the base station 105-b may send the time delay as the time parameter. In some other examples, the capability message may indicate that the UE 115-b supports a configuration duration, and thus the base station 105-b may send the configuration duration as the time parameter.

[0142] At 515, UE 115-b may identify a time parameter from the indication. In some cases, the time parameter may be a time delay (e.g., a determination timeline as described herein) at 520. In some other cases, the time parameter may be a configured duration at 525. In some examples, UE 115-b may identify both the time delay and the configured duration.

[0143] At 530, the base station 105-b may indicate the time slot configuration to the UE 115-b. In some cases, the time slot configuration may be associated with a time slot duration. The time slot duration may include a flexible symbol period that supports uplink communication, downlink communication, or a combination thereof. In some cases, if the UE 115-b identifies the time parameter as a configuration duration, the UE 115-b may refrain from monitoring for additional indications of the time slot configuration during the configuration duration. Once the configuration duration expires, the UE 115-b may resume monitoring for additional indications.

[0144] At 535, base station 105-b may indicate a determination mode to UE 115-b. In some cases, the determination mode may be a first determination mode. The first determination mode may correspond to a configuration that determines a single time slot duration. In some other cases, the determination mode may be a second determination mode. The second determination mode may correspond to a configuration that determines a plurality of time slot durations.

[0145] At 540, UE 115-b may apply the determined pattern received at 535. For example, UE 115-b may configure a single time slot duration, or repeat the determined configuration.

[0146] At 545, UE 115-b may determine a configuration for one or more time slot durations. For example, if the time parameter is a time delay, UE 115-b may wait until after the time delay to configure a single time slot duration. If the time parameter is a configuration duration, UE 115-b may determine a configuration for a single time slot duration within the identified duration (e.g., according to a first determination mode). Additionally or alternatively, UE 115-b may determine a configuration for a first time slot duration within the identified duration and then repeat the determined configuration for one or more additional time slot durations within the configuration duration (e.g., according to a second determination mode). In some other examples where the time parameter is a time delay, UE 115-b may determine a configuration for the first time slot duration after the time delay. UE 115-b may also repeat the determined configuration for one or more additional time slot durations after the time delay. If the time parameter is a configuration duration, in some cases, UE 115-b may repeat the determined configuration until a specified repetition period ends, or until a second indication of the time slot configuration is received.

[0147] In some cases, UE 115-b may determine the configuration based on the direction of communication (e.g., uplink or downlink) for the time slot duration. In some other cases, UE 115-b may determine the configuration based on the type of channel scheduled for communication during the time slot duration. For example, the channel may be a PUSCH, a PDSCH, or a downlink data channel. In some examples, UE 115-b may receive a time slot configuration (e.g., a time slot configuration different from the time slot configuration at 530) from base station 105-b, which may indicate a portion of the time slot duration to be used for uplink transmission. For example, the portion of the time slot duration may include one or more symbol periods.

[0148] At 550 , the UE 115 - b and the base station 105 - b may communicate during one or more time slot durations based on the configuration determined at 540 .
