[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 981,415, entitled "PRE - CONFIGURED ACTIVATION AND DEACTIVATION", filed on February 25, 2020, and U.S. Non - Provisional Patent Application No. 17 / 182,934, entitled "PRE - CONFIGURED ACTIVATION AND DEACTIVATION", filed on February 23, 2021, the disclosures of which are hereby expressly incorporated herein by reference. Field of the technology

[0003] Aspects of the present disclosure generally relate to wireless communication and techniques and apparatus for pre - configured activation and deactivation. Background art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ a multiple access technology that is capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single - Carrier Frequency Division Multiple Access (SC - FDMA) systems, and Time Division - Synchronous Code Division Multiple Access (TD - SCDMA) systems, as well as Long Term Evolution (LTE). LTE / LTE - Advanced is a collection of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include several base stations (BSs) capable of supporting communication for several user equipments (UEs). The UEs may communicate with the BSs via downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, the BS may be referred to as Node B, gNB, access point (AP), radio head, transmit - receive point (TRP), New Radio (NR) BS, 5G Node B, and so on.

[0006] The above-mentioned multiple access technologies have been used in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the urban, national, regional, or even global level. NR (which can also be referred to as 5G) is a collection of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing costs, enhancing services, leveraging new spectrums, and better integrating with other open standards that use orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) (CP-OFDM) on the downlink (DL), and CP-OFDM and / or SC-FDM (e.g., also referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. With the increasing demand for mobile broadband access, further improvements to LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0011] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a UE, may cause the one or more processors to: receive activation signaling for a configuration of a semi-persistent transmission procedure; activate the semi-persistent transmission procedure at least in part based on the received activation signaling; and deactivate the semi-persistent transmission procedure at least in part based on a deactivation time.

[0012] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication.

[0024] The various aspects of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout the present disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should understand that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of any other aspect of the present disclosure or in combination with any other aspect of the present disclosure. For example, any number of the aspects set forth herein may be used to implement a device or practice a method. Additionally, the scope of the disclosure is intended to cover devices or methods practiced using additional or other structures, functionality, or a combination of structures and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements in the claims.

[0025] Aspects of a telecommunications system will now be presented with reference to various apparatus and techniques. These apparatus and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0026] Note that while aspects may be described using terms typically associated with 5G or NR radio access technology (RAT), aspects of the present disclosure can be applied to other RATs such as 3G RAT, 4G RAT, and / or post-5G RAT (e.g., 6G).

[0027] Figure 1 FIG. is a diagram illustrating an example of a wireless network 100 in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, etc. The wireless network 100 may include several base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a particular geographic area. In 3GPP, depending on the context in which the term "cell" is used, the term "cell" may refer to the coverage area of a BS and / or the BS subsystem serving this coverage area.

[0028] The BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., with a radius of several kilometers) and may allow unrestricted access by UEs having a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs having a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow limited access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1In the example shown, BS110a can be a macro BS for macro cell 102a, BS110b can be a pico BS for pico cell 102b, and BS110c can be a femto BS for femto cell 102c. The BS can support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" can be used interchangeably herein.

[0029] In some aspects, the cell may not necessarily be fixed, and the geographical area of the cell can move according to the location of the mobile BS. In some aspects, the BSs can be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces such as direct physical connections or virtual networks using any suitable transport network.

[0030] The wireless network 100 can also include relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit the data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. In Figure 1 the example shown, relay BS110d can communicate with macro BS110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, relay base station, relay, etc.

[0031] The wireless network 100 can be a heterogeneous network including different types of BSs such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs can have different transmission power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS can have a high transmission power level (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmission power levels (e.g., 0.1 to 2 watts).

[0032] The network controller 130 can be coupled to a set of BSs and can provide coordination and control for these BSs. The network controller 130 can communicate with the BSs via the backhaul. The BSs can also communicate with each other directly or indirectly via wireless or wired backhaul.

[0033] UE 120 (e.g., 120a, 120b, 120c) can be spread throughout the wireless network 100, and each UE can be fixed or mobile. A UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. A UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, a superbook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle-mounted component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via wireless or wired media.

[0034] Certain UEs can be considered machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node can provide connectivity to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Certain UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as narrowband IoT (NB-IoT) devices. Certain UEs can be considered customer premises equipment (CPE). UE 120 can be included within a housing that houses components of UE 120 such as a processor component and / or a memory component. In some aspects, the processor component and the memory component can be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., a memory) can be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0035] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network can be deployed.

[0036] In some aspects, two or more UEs 120 (e.g., shown as UEs 120a and 120e) may communicate directly using one or more sidelink channels (e.g., without using the base station 110 as an intermediary for communicating with each other). For example, the UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In such cases, the UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by the base station 110.

[0037] Devices of the wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1) that may span from 410 MHz to 7.125 GHz, and / or may communicate using an operating band having a second frequency range (FR2) that may span from 24.25 GHz to 52.6 GHz. The frequency between FR1 and FR2 is sometimes referred to as the mid-band frequency. Although part of FR1 is greater than 6 GHz, FR1 is often referred to as the "sub-6 GHz" band. Similarly, FR2 is often referred to as the "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) identified by the International Telecommunication Union (ITU) as the "millimeter wave" band. Thus, unless otherwise specifically stated, it should be understood that if used herein, terms such as "sub-6 GHz" may broadly represent frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise specifically stated, it should be understood that if used herein, terms such as "millimeter wave" may broadly represent frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein apply to those modified frequency ranges.

[0038] As described above, Figure 1 is provided as an example. Other examples may be different from the example regarding Figure 1 described.

[0039] Figure 2FIG. is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 254a to 254r, where typically T≥1 and R≥1.

[0040] At the base station 110, a transmit processor 220 may receive data for one or more UEs from a data source 212, select one or more modulation and coding schemes (MCSs) for each UE at least in part based on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE at least in part based on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 may process the corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process the output sample stream (e.g., convert to analog, amplify, filter, and upconvert) to obtain a downlink signal. The T downlink signals from the modulators 232a to 232t may be transmitted via the T antennas 234a to 234t, respectively.

[0041] At the UE 120, antennas 252a through 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide the received signals to demodulators (DEMOD) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 256 may obtain the received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols if applicable, and provide the detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for the UE 120 to the data sink 260, and provide the decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine reference signal received power (RSRP) parameters, received signal strength indicator (RSSI) parameters, reference signal received quality (RSRQ) parameters, and / or channel quality indicator (CQI) parameters, etc. In some aspects, one or more components of the UE 120 may be included in a housing.

[0042] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0043] Antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) may include one or more antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays or may be included in one or more antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays, etc. The antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays may include one or more antenna elements. The antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays may include a collection of coplanar antenna elements and / or a collection of non-coplanar antenna elements. The antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. The antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays may include one or more antenna elements coupled to one or more transmit and / or receive components (such as Figure 2 one or more components) of

[0044] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may also generate reference symbols for one or more reference signals. Symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 when applicable, further processed by demodulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, a modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modulator and / or demodulator 254, an MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and a memory 282 to perform aspects of any of the methods described herein (e.g., as referenced Figures 3 - 6 described).

[0045] At the base station 110, uplink signals from the UE 120 and other UEs may be received by an antenna 234, processed by a demodulator 232, detected by an MIMO detector 236 when applicable, and further processed by a receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with a network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communication. In some aspects, a modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of an antenna 234, a modulator and / or demodulator 232, an MIMO detector 236, a receive processor 238, a transmit processor 220, and / or a TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and a memory 242 to perform aspects of any of the methods described herein (e.g., as referenced Figures 3 - 6 described).

[0046] As described in more detail elsewhere herein, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 any other component of may perform one or more techniques associated with pre-configured activation or deactivation. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 any other component of may perform or direct the operation of, for example Figure 5 process 500 of, Figure 6 process 600 of, and / or other processes described herein. The memories 242 and 282 may store data and program code for the base station 110 and the UE 120, respectively. In some aspects, the memory 242 and / or the memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when the one or more instructions are executed (e.g., directly, or after compilation, transformation, and / or interpretation) by one or more processors of the base station 110 and / or the UE 120, the one or more processors, the UE 120, and / or the base station 110 may be caused to perform or direct the operation of, for example Figure 5 process 500 of, Figure 6 process 600 of, and / or other processes described herein. In some aspects, executing the instructions may include running the instructions, transforming the instructions, compiling the instructions, and / or interpreting the instructions, and so on.

[0047] In some aspects, the UE 120 may include components for receiving (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, memory 282, etc.) activation signaling for the configuration of a semi-persistent transmission process, components for activating (e.g., using controller / processor 280) the semi-persistent transmission process at least in part based on the received activation signaling, components for deactivating (e.g., using controller / processor 280) the semi-persistent transmission process at least in part based on a deactivation time, and so on. In some aspects, the UE 120 may include components for transmitting (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, etc.) uplink feedback in response to an attempt to receive a downlink transmission, components for activating (e.g., using controller / processor 280) a semi-persistent scheduling opportunity or pre-configured resources for retransmission at least in part based on transmitting the uplink feedback, components for communicating (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, etc.) during the semi-persistent scheduling opportunity or using the pre-configured resources for retransmission, and so on. In some aspects, such components may include one or more components of the UE 120 described in conjunction with Figure 2 such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD

[0048] 254, MIMO detector 256, receive processor 258, and so on.

[0049] Although Figure 2 the boxes in are shown as different components, the functions described above with respect to these boxes may be implemented in a single hardware, software, or combined component or various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0050] As described above, Figure 2 is provided as an example. Other examples may differ from the example described with respect to Figure 2 .

[0051] In some communication systems, the semi-persistent transmission procedure can be used to enable a UE to communicate using semi-persistent resources. For example, a BS can configure for a UE a semi-persistent scheduling (SPS) / configured grant (CG) state in which the UE can perform periodic transmissions on the uplink. Additionally or alternatively, the BS can configure for the UE a state associated with semi-persistent channel state information reference signal (CSI-RS), semi-persistent sounding reference signal (SRS), discontinuous reception (DRX) mode communication, etc. The semi-persistent resources are the resources indicated to the UE by such configurations, which can recur over a period of time. The BS can send a first downlink control information (DCI) to activate, for example, the SPS / CG state, and the UE can operate in the SPS / CG state (e.g., use the semi-persistent resources) until the BS sends a second DCI to deactivate the SPS / CG state. The SPS / CG or other states can be referred to herein as the SPS / CG procedure, the semi-persistent transmission procedure, etc. However, in some cases, before the UE starts the semi-persistent transmission procedure, the duration for which the UE will operate using the semi-persistent transmission procedure can be determinable. For example, the BS can determine to switch the UE from a first component carrier to a second component carrier and use the SPS / CG state on the second component carrier to avoid interference on the first component carrier during a pre-configured time period when another communication will appear on the first component carrier. Additionally or alternatively, the BS can determine to switch the UE from a first component carrier to a second component carrier and use the SPS / CG state on the second component carrier because some higher-priority traffic will use the resources on the first component carrier (e.g., a higher-priority SPS or CG for another UE). Thus, whether due to interference, higher-priority traffic, or other reasons, a known or expected interference or interruption with a known duration can be mitigated by the BS sending activation signaling for a configuration of the semi-persistent transmission procedure with a deactivation time, and the semi-persistent transmission procedure can be deactivated after that deactivation time (without explicit deactivation signaling).

[0052] Certain aspects described herein can eliminate the need for DCI signaling in activating or deactivating a semi-persistent transmission process. For example, the BS can send DCI to activate a semi-persistent transmission process and can include information identifying a deactivation time for the semi-persistent transmission process. In this case, after the deactivation time expires, the UE can automatically deactivate the semi-persistent transmission process without receiving DCI. In this way, the BS and the UE reduce the signaling associated with using, for example, SPS / CG states. Additionally or alternatively, the semi-persistent transmission process (e.g., SPS / CG state) can be automatically activated at least in part based on the transmission of uplink feedback. For example, instead of waiting for DCI to activate resources for retransmission of a failed communication, the UE can send uplink feedback indicating the failed communication to the BS, which can automatically activate the retransmission using SPS resources or pre-configured retransmission resources (e.g., CG resources). In this way, the UE and the BS eliminate the need for DCI-based activation of transmission resources, thereby reducing the utilization of network resources.

[0053] Figure 3 is a diagram illustrating an example 300 of pre-configured deactivation according to the present disclosure. As Figure 3 shown, example 300 includes BS 110 and UE 120.

[0054] As Figure 3 further shown, and by reference numeral 310, BS 110 can send activation signaling to UE 120 for a semi-persistent transmission process. The activation signaling is signaling that causes UE 120 to activate a semi-persistent transmission process or an SPS transmission occasion associated with an SPS transmission process. For example, BS 110 can send DCI to activate SPS / CG transmission (e.g., SPS / CG state). Additionally or alternatively, BS 110 can send signaling to activate semi-persistent CSI-RS signaling, semi-persistent SRS signaling, DRX mode communication, etc.

[0055] In certain aspects, UE 120 can identify the deactivation time at least in part based on DCI. For example, UE 120 can parse the DCI to identify an identifier of the included deactivation time (e.g., the time for which the SPS / CG transmission will be active). Additionally or alternatively, UE 120 can receive information identifying the deactivation time via a separate signal. For example, UE 120 can receive radio resource control (RRC) signaling configuring the deactivation time for one or more subsequent SPS / CG transmission activations. Additionally or alternatively, UE 120 can receive a medium access control (MAC) control element (CE) identifying the deactivation time for one or more SPS / CG transmission activations.

[0056] In some aspects, BS110 can provide a deactivation time indicator for a specific group of SPS / CG configuration identifiers. For example, BS110 can provide a deactivation time indicator associated with one or more SPS / CG configuration identifiers such that the deactivation time applies to SPS / CG activation associated with one or more SPS / CG configuration identifiers. In some aspects, BS110 can provide the deactivation time indicator to a specific group of UEs 120. For example, BS110 can send a broadcast message, a multicast message, etc. to UE 120 and / or one or more other UEs 120 to identify the deactivation time for UE 120 and / or one or more other UEs 120. Additionally or alternatively, BS110 can send group common DCI to UE 120 (and / or one or more other UEs 120) to identify the deactivation time. In this way, BS110 reduces the utilization of network resources as compared to sending individual signaling to each UE 120 in the network.

[0057] As Figure 3 As further shown and by reference numeral 320, UE 120 can activate a semi-persistent transmission process. For example, UE 120 can activate SPS / CG transmission and / or SPS / CG status. In some aspects, UE 120 can immediately activate SPS / CG transmission at least in part based on receiving DCI. Additionally or alternatively, UE 120 can activate SPS / CG transmission at a threshold time after receiving DCI to maintain synchronization with BS110.

[0058] As Figure 3 As further shown and by reference numeral 330, UE 120 can detect the expiration of the deactivation time and deactivate the semi-persistent transmission process. For example, UE 120 can deactivate SPS / CG transmission at least in part based on the expiration of the deactivation time. In some aspects, UE 120 can delay the deactivation of SPS / CG transmission. For example, when UE 120 detects that there is still remaining data to be transmitted using SPS / CG resources, UE 120 can extend SPS / CG transmission to accommodate the remaining data and can deactivate SPS / CG transmission after the extension of SPS / CG transmission ends. In some aspects, UE 120 can enter a default configuration after deactivating SPS / CG transmission. For example, UE 120 can be configured (e.g., by BS110) with a default SPS / CG configuration and can return to the default SPS / CG configuration after deactivation. Additionally or alternatively, UE 120 can switch component carriers after deactivation. For example, when UE 120 switches from a first carrier to a second carrier to activate SPS / CG transmission on the second carrier, UE 120 can return to the first carrier after deactivating SPS / CG transmission on the second carrier.

[0059] As described above, Figure 3 is provided as an example. Other examples may be different from those Figure 3 described with respect to

[0060] Figure 4 is a diagram illustrating example 400 of uplink feedback-based activation according to the present disclosure. As Figure 4 shown, example 400 includes BS110 and UE 120.

[0061] As Figure 4 further shown, and by reference numeral 410, UE 120 may send uplink feedback to BS110. For example, UE 120 may send uplink feedback such as hybrid automatic repeat request (HARQ) feedback, which includes one or more bits indicating one or more acknowledgments (ACKs) or negative acknowledgments (NACKs) for one or more communications. In some aspects, UE 120 may send uplink feedback including one or more ACKs, one or more NACKs, a combination of one or more ACKs and one or more NACKs, etc. In some aspects, UE 120 may send uplink feedback including an activation indicator. For example, UE 120 may send uplink feedback with an explicit indicator requesting activation of the identified SPS configuration associated with a particular SPS configuration identifier. In this case, UE 120 may use a single bit configured to correspond to a single SPS configuration identifier to request activation of an SPS occasion (also referred to herein as an SPS process) and / or utilization of preconfigured retransmission resources (e.g., time resources and / or frequency resources). Additionally or alternatively, UE 120 may use multiple bits to explicitly identify the SPS configuration identifier. In some aspects, UE 120 may send an explicit indicator separate from the uplink feedback.

[0062] In some aspects, UE 120 may include scheduling information in the uplink feedback. For example, UE 120 may identify scheduling information for activation enabling use of retransmission resources. In some aspects, the scheduling information may conflict with previously configured scheduling information. In such a case, UE 120 and / or BS110 may override the previously configured scheduling information with the scheduling information notified by UE signaling.

[0063] As Figure 4Further shown, and by reference numeral 420, UE 120 may activate SPS timing and / or utilization of pre-configured retransmission resources. For example, at least partially based on sending uplink feedback with at least one NACK, UE 120 may activate SPS timing. In this way, UE 120 eliminates the need to receive DCI from BS110, thereby reducing the utilization of network resources. In some aspects, UE 120 may activate SPS timing at least partially based on at least one NACK corresponding to a particular Hybrid Automatic Repeat reQuest (HARQ) identifier.

[0064] Additionally or alternatively, UE 120 may activate SPS / CG transmission at least partially based on at least one NACK related to a particular Physical Layer (PHY) priority. For example, when UE 120 detects a failure of a Physical Downlink Shared Channel (PDSCH) with a relatively high priority (e.g., as indicated in scheduling DCI including a priority indicator for PDSCH), UE 120 may send a NACK to indicate the PDSCH failure and may automatically activate SPS / CG transmission. In some aspects, UE 120 may activate SPS timing or utilization of pre-configured retransmission resources at least partially based on uplink feedback that includes only NACKs. For example, UE 120 may determine that the uplink feedback includes one or more NACKs and does not include an ACK, and may determine to activate SPS timing and / or pre-configured retransmission resources to enable retransmission of the failed communication.

[0065] In some aspects, UE 120 may utilize a particular SPS configuration to activate SPS timing. For example, for SPS communication, UE 120 may use a pre-configured SPS configuration that identifies a set of time resources, a set of frequency resources, a Modulation and Coding Scheme (MCS), a beam, a periodicity, an offset for start time, etc. In this case, UE 120 may start SPS communication at a particular time after sending uplink feedback, such as the first scheduled SPS after sending uplink feedback, the first scheduled SPS after a minimum or threshold time period (e.g., UE and / or BS processing time) after sending uplink feedback, etc.

[0066] Additionally or alternatively, UE 120 may utilize an SPS configuration indicated by UL feedback to activate SPS timing. For example, UE120 may explicitly identify the configuration of the SPS timing that UE 120 will use when sending UL feedback. Additionally or alternatively, UE 120 may send UL feedback that enables BS110 to implicitly identify the SPS configuration. For example, the timing of the UL feedback may correspond to a particular SPS configuration among multiple possible SPS configurations.

[0067] As described above, Figure 4 is provided as an example. Other examples may be different from those Figure 4 described with respect to

[0068] Figure 5 is a diagram illustrating an example process 500 performed by a UE, for example, according to the present disclosure. The example process 500 is an example in which a UE (e.g., UE 120, etc.) performs operations associated with preconfigured deactivation.

[0069] As Figure 5 shown, in some aspects, process 500 may include receiving activation signaling for configuring a semi-persistent transmission process (block 510). For example, as described above with reference to Figure 3 a UE (e.g., using the receiving processor 258, the transmitting processor 264, the controller / processor 280, the memory 282, etc.) may receive activation signaling for configuring a semi-persistent transmission process.

For example, the activation signaling may activate a configuration for one or more SPS transmission process timings (e.g., one or more SPS timings).

Additionally or alternatively, two or more of the boxes of process 500 may be performed in parallel.

[0084] Figure 6 is a diagram illustrating an example process 600 performed, for example, by a UE in accordance with the present disclosure. Example process 600 is an example in which a UE (e.g., UE 120, etc.) performs operations associated with activation based on uplink feedback.

[0085] As Figure 6 shown, in some aspects, process 600 may include sending uplink feedback (block 610) in response to an attempt to receive a downlink transmission. For example, as described above with reference to Figure 4 a UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may send uplink feedback in response to an attempt to receive a downlink transmission.

[0086] As Figure 6 further shown, in some aspects, process 600 may include activating a semi-persistent scheduling opportunity or preconfigured resources for retransmission (block 620) at least in part based on sending the uplink feedback.

[0087] As Figure 6 further shown, in some aspects, process 600 may include communicating in the semi-persistent scheduling opportunity or using the preconfigured resources for retransmission (block 630). For example, as described above with reference to Figure 4 a UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may communicate in the semi-persistent scheduling opportunity or use the preconfigured resources for retransmission.
