[0002] This patent application claims the benefit of U.S. patent application No. 17 / 941,967, filed by Ly et al. on September 9, 2022, entitled “TECHNIQUES FOR DYNAMIC TRANSMISSION PARAMETER ADAPTATION,” which is assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field

[0003] The following relates to wireless communications, including techniques for dynamic transmission parameter adaptation. 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 techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (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, each of which supports wireless communications for communication devices, which may be referred to as user equipment (UE). Summary of the invention

[0005] The technology relates to improved methods, systems, devices and apparatuses that support technology for dynamic transmission parameter adaptation. For example, the technology provides a parameter switching timeline to support dynamic transmission parameter adaptation. A network entity may dynamically adapt a transmission parameter at the network entity to reduce network power consumption. A UE may switch between parameter sets on the network entity side according to the parameter switching timeline to implement transmission parameter adaptation. The parameter switching timeline may include a transient time (e.g., the time between receiving a configuration update indication and applying the indicated configuration), a parameter reconfiguration gap (e.g., the gap between the current configuration and the indicated configuration), and a duration between configuration updates. The UE may be configured to operate or communicate according to the parameter switching timeline to support dynamic transmission parameter adaptation. The parameter switching timeline may be preconfigured or may be based on UE capabilities. For example, the UE may indicate a supported time or a minimum supported time for the duration, timer or gap of the transmission parameter adaptation timeline. In some examples, the starting symbol or time slot of these durations may be based on the type of signaling used to transmit the configuration update indication. These durations may be defined or configured based on symbols, time slots, or frames, and may also be determined based on a currently configured subcarrier spacing, a second configured subcarrier spacing, or a fixed subcarrier spacing.

[0051] A network entity may dynamically adapt transmission parameters at the network entity to reduce network power consumption. For example, the network entity may modify the number of antenna ports used at the network entity antenna or the transmission power used for downlink signals and channels. The network entity may be able to quickly adjust the transmission parameters. For example, the network entity may be able to dynamically adapt the transmission parameters within a time slot or less. However, fast transmission parameter adaptation may affect the complexity (because the user equipment (UE) may frequently update system parameters) and the performance at the UE communicating with the network entity. For example, it may not be possible to combine or average channel state information (CSI), radio link monitoring (RLM), radio resource management (RRM), or beam management measurement results obtained under different transmission parameters to obtain reliable measurement results. For example, if the transmission parameter set is accidentally switched, the UE may not be able to obtain reliable measurement results by combining the measurement results obtained under two separate transmission parameter sets.

[0052] The wireless communication system described herein supports a parameter switching timeline for dynamic transmission parameter adaptation. The UE may switch between parameter sets on the network entity side according to the parameter switching timeline to implement transmission parameter adaptation. For example, the UE may switch to a second transmission parameter set according to the parameter switching timeline to reduce network-side power consumption without increasing UE complexity. The parameter switching timeline may, for example, enable the UE to average or merge measurement results at the end of a period of using a first transmission parameter set (e.g., before switching to a second transmission parameter set), thereby obtaining accurate and reliable measurement results for communications performed according to the first transmission parameter set.

[0053] The parameter switching timeline may include a transient time (e.g., the time from receiving a configuration update indication to applying the indicated configuration), a parameter reconfiguration gap (e.g., the gap between the current configuration and the indicated configuration), and a duration between configuration updates. The UE may be configured to operate or communicate according to the parameter switching timeline to support dynamic transmission parameter adaptation. The parameter switching timeline may be pre-configured or may be based on UE capabilities. For example, the UE may indicate a supported time or a minimum supported time for the duration, timer, or gap of the transmission parameter adaptation timeline. In some examples, the starting symbol or time slot of these durations may be based on the type of signaling used to transmit the configuration update indication. These durations may be defined or configured based on symbols, time slots, or frames, and may also be determined based on a currently configured subcarrier spacing, a second configured subcarrier spacing, or a fixed subcarrier spacing.

[0054] Such specific implementations of the subject matter described in the present disclosure may also be implemented to achieve one or more of the following potential advantages. For example, by performing dynamic transmission parameter adaptation according to a parameter switching timeline, a network entity may switch between transmission parameter sets to reduce network-side power consumption without affecting UE complexity or procedures. These techniques may reduce power consumption from the network entity, such as by changing the transmission power of downlink signaling or changing the number of antenna ports used by the network entity. The parameter switching timeline may provide the UE with sufficient time to re-tune or modify the UE's radio frequency components according to the updated parameter set. In addition, the parameter switching timeline may let the UE know the update time of the parameter set, which may ensure that the transmission parameters remain unchanged within certain time intervals of the parameter switching timeline or increase the likelihood that the transmission parameters remain unchanged during this period. When the parameters are consistent, the UE may perform measurements; when the transmission parameter set is about to be updated, the UE may prepare to reset the time-frequency tracking loop.

[0055] Aspects of the disclosure are first described in the context of a wireless communication system. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams involving techniques for dynamic transmit parameter adaptation.

[0056] Figure 1 An example of a wireless communication system 100 supporting techniques for dynamic transmission parameter adaptation according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 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 advanced LTE (LTE-A) network, an LTE-A Pro network, a new radio (NR) network, or a network operating according to other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0057] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other nomenclature. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0058] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile or both stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1 . The UEs 115 described herein may be capable of supporting communications with various types of devices, such as Figure 1 Other UEs 115 or network entities 105 are shown.

[0059] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.

[0060] In some examples, the network entities 105 may communicate with the core network 130 or with each other or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3 or other interface protocols). In some examples, the network entities 105 may communicate with each other via the backhaul communication links 120 (e.g., according to X2, Xn or other interface protocols) directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130). In some examples, the network entities 105 may communicate with each other via the midhaul communication links 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication links 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication links 120, the midhaul communication links 162, or the fronthaul communication links 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0061] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a Home Node B, a Home Evolved Node B, or other suitable terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, stand-alone) base station architecture, which may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0062] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0063] The functional split between CU 160, DU 165, and RU 170 is flexible and may support different functions depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DUs 165 and RUs 170, such that the DUs 165 may support one or more layers of the protocol stack, and the RUs 170 may support one or more different layers of the protocol stack. The DUs 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by different ones of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that communicate via such communication links.

[0064] In some wireless communication systems (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DUs 165 or one or more RUs 170 may be controlled in part by one or more CUs 160 associated with a donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a coupled IAB donor's DU 165. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0065] For example, an access network (AN) or RAN may include an access node (e.g., an IAB donor), communications between an IAB node 104, and one or more UEs 115. The IAB donor may facilitate connectivity between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, the IAB donor may refer to a RAN node having a wired or wireless connection to the core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170), wherein the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB donor and the IAB node 104 may communicate via an F1 interface according to a protocol defining signaling messages (e.g., an F1 AP protocol). Additionally or alternatively, CU 160 may communicate with the core network via an interface (which may be an example of a portion of a backhaul link) and may communicate with other CUs 160 (e.g., CU 160 associated with an alternative IAB donor) via an Xn-C interface (which may be an example of a portion of a backhaul link).

[0066] An IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UE 115, wireless self-backhaul capabilities, etc.). The DU 165 may act as a distributed scheduling node toward child nodes associated with the IAB node 104, and the IAB-MT may act as a scheduled node toward a parent node associated with the IAB node 104. That is, an IAB donor may be referred to as a parent node that communicates with one or more child nodes (e.g., the IAB donor may relay for transmissions to UEs through one or more other IAB nodes 104). Additionally or alternatively, depending on the relay chain or configuration of the AN, the IAB node 104 may also be referred to as a parent node or child node of other IAB nodes 104. Thus, the IAB-MT entity of the IAB node 104 may provide a Uu interface for the child IAB node 104 to receive signaling from the parent IAB node 104 , and a DU interface (eg, DU 165 ) may provide a Uu interface for the parent IAB node 104 to signal to the child IAB node 104 or the UE 115 .

[0067] For example, the IAB node 104 may be referred to as a parent node supporting communications for a child IAB node or as a child node associated with an IAB donor, or both. The IAB donor may include a CU 160 having a wired or wireless connection (e.g., backhaul communication link 120) to the core network 130, and may act as a parent node of the IAB node 104. For example, the DU 165 of the IAB donor may relay transmissions to the UE 115 via the IAB node 104, or may directly signal the transmissions to the UE 115, or both. The CU 160 of the IAB donor may signal the establishment of a communication link to the IAB node 104 via the F1 interface, and the IAB node 104 may schedule transmissions (e.g., transmissions relayed from the IAB donor to the UE 115) via the DU 165. That is, data may be relayed to and from the IAB node 104 via signaling via the NR Uu interface of the MT to the IAB node 104. Communications with the IAB node 104 may be scheduled by the DU 165 of the IAB donor, and communications with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104 .

[0068] Where the techniques described herein are applied in the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support the techniques for dynamic transmission parameter adaptation as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0069] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0070] 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 network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0071] The UE 115 and the network entity 105 may use resources associated with one or more carriers to wirelessly communicate with each other via one or more communication links 125 (e.g., access links). The term "carrier" may refer to a collection of RF spectrum resources having a physical layer structure defined to support the communication link 125. For example, a carrier for the communication link 125 may 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 may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between these devices and any part (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send", "receive", or "communicate" when referring to the network entity 105 may refer to any part of the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0072] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be identified according to a channel raster for discovery by UE 115. A carrier may operate in a standalone mode, in which case initial acquisition and connection may be performed by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which case the connection is anchored using a different carrier (e.g., a different carrier of the same or different radio access technology).

[0073] The communication link 125 shown in the wireless communication system 100 may include downlink transmissions (e.g., forward link transmissions) from the network entity 105 to the UE 115, uplink transmissions (e.g., return link transmissions) from the UE 115 to the network entity 105, or both, among other transmission configurations. A carrier may carry either downlink communications or uplink communications (e.g., in an FDD mode), or may be configured to carry both downlink communications and uplink communications (e.g., in a TDD mode).

[0074] A carrier may be associated with a particular bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a set of bandwidths (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz) of a carrier of a particular radio access technology. A device (e.g., a network entity 105, a UE 115, or both) of the wireless communication system 100 may have a hardware configuration that supports communications using a particular carrier bandwidth or may be capable of being configured to support communications using one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a network entity 105 or a UE 115 that supports concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., a sub-band, a BWP) or all of a carrier bandwidth.

[0075] The signal waveform transmitted via the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system using MCM techniques, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and the subcarrier spacing may be 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), so that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high order modulation scheme may correspond to a relatively high rate of communication. 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 resources may increase the data rate or data integrity used for communication with UE 115.

[0076] One or more parameter sets for a carrier may be supported, and the parameter sets may include subcarrier spacing (Δf) and cyclic prefixes. A carrier may be divided into one or more BWPs with the same or different parameter sets. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications of a UE 115 may be constrained to one or more active BWPs.

[0077] The time interval for the network entity 105 or the UE 115 may be expressed as a multiple of a basic time unit, which may be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, for which Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. Time intervals of the communication resources may be organized according to radio frames, each having 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).

[0078] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of micro time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0079] A subframe, slot, mini-slot, or symbol may be the smallest 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 smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0080] According to various techniques, physical channels may be multiplexed using carriers for communication. Physical control channels and physical data channels may be multiplexed for signaling via downlink carriers, for example, 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)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth of a carrier or a subset of that system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE115 may monitor or search a control region to obtain control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded 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 .

[0081] The network entity 105 may 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" may refer to a logical communication entity used to communicate with the network entity 105 (e.g., using a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other cell identifier) ​​used to distinguish adjacent cells. In some examples, a cell may also refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) on which the logical communication entity operates. Depending on various factors such as the capabilities of the network entity 105, such cells may range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or may include a building, a subset of a building, or an external space between or overlapping coverage areas 110, and the like.

[0082] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have service subscriptions with a network provider that supports the macro cell. Small cells may be associated with lower power network entities 105 (e.g., lower power base stations 140) than macro cells, and small cells may operate using the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with small cells (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A network entity 105 may support one or more cells, and may also use one or more component carriers to support communications via one or more cells.

[0083] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0084] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0085] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) may have similar frame timing, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, the network entities 105 may have different frame timing, and in some examples, transmissions from different network entities 105 may not be aligned in time. The techniques described herein may be used for either synchronous operation or asynchronous operation.

[0086] 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 technology that allows devices to communicate with each other or with a network entity 105 (e.g., base station 140) without human intervention. In some examples, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or acquire information and relay such information to a central server or application that uses the information or presents the information 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, health care monitoring, wildlife monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0087] Some UEs 115 may be configured to employ an operating mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but does not transmit and receive concurrently). In some examples, half-duplex communication may be performed at a reduced peak rate. Other energy-saving techniques for UE 115 include entering a power-saving deep sleep mode when not engaged in active communications, operating using limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is 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 a carrier.

[0088] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communication may include private communication or group communication, and may be supported by one or more services (such as push-to-talk, video, or data). Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms "ultra-reliable", "low latency", and "ultra-reliable low latency" are used interchangeably herein.

[0089] In some examples, the UE 115 may be configured to support communication directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group that are performing D2D communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 in such a group may be outside of the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.

[0090] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these items. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in the V2X system can communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170) using vehicle-to-network (V2N) communication, or both.

[0091] 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)) for managing 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)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management of UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP service 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0092] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength ranges from about one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves may be sufficient to penetrate structures so that macro cells provide services to UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) compared to communications using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0093] The wireless communication system 100 may also operate using a super high frequency (SHF) region (also known as a centimeter band) that may be in the range of 3 GHz to 30 GHz or an extremely high frequency (EHF) region (e.g., 30 GHz to 300 GHz) (also known as a millimeter band) using a spectrum. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and network entity 105 (e.g., base station 140, RU 170), and the EHF antenna of the corresponding device may be smaller and closer than the UHF antenna. In some examples, such technology may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be affected by greater attenuation and shorter range than SHF or UHF transmissions. The technology disclosed herein may be adopted across transmissions using one or more different frequency regions, and the use of frequency bands specified across these frequency regions may vary by country or regulatory agency.

[0094] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology. When operating using unlicensed RF spectrum bands, devices such as network entity 105 and UE 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands may be based on carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating using licensed bands. Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0095] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which may 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, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a set of antenna ports of multiple rows and columns that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0096] The network entity 105 or UE 115 may use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such technology may be referred to as spatial multiplexing. Multiple signals may be, for example, sent by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals may be received by a receiving device 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 information 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 technologies include: single-user MIMO (SU-MIMO), in which multiple spatial layers are sent to the same receiving device; and multi-user MIMO (MU-MIMO), in which multiple spatial layers are sent to multiple devices.

[0097] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals conveyed via antenna elements of an antenna array so that some signals propagating along a particular direction relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed via antenna elements may include the transmitting device or the 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 these antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0098] The network entity 105 or UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the network entity 105 along different directions. For example, the network entity 105 may send signals according to different sets of beamforming weights associated with different transmission directions. Transmission along different beam directions may be used to identify (e.g., by a transmitting device (such as network entity 105), or by a receiving device (such as UE 115)) a beam direction for later transmission or reception by the network entity 105.

[0099] Some signals, such as data signals associated with a particular receiving device, may be sent by a sending device (e.g., sending network entity 105, sending UE 115) along a single beam direction (e.g., a direction associated with a receiving device (such as receiving network entity 105 or receiving UE 115)). In some examples, the beam direction associated with the transmission along the single beam direction may be determined based on signals sent along one or more beam directions. For example, UE 115 may receive one or more of the signals sent by network entity 105 along different directions, and may report to network entity 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0100] In some examples, transmission by a device (e.g., by network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more subbands. Network entity 105 may send a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may be precoded or non-precoded. UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel codebook, a linear combination codebook, a port selection codebook). Although these techniques are described with reference to signals sent along one or more directions by a network entity 105 (e.g., base station 140, RU 170), UE 115 may use similar techniques to send signals multiple times along different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to send signals along a single direction (e.g., to send data to a receiving device).

[0101] A receiving device (e.g., UE 115) may perform receiving operations according to multiple receiving configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a receiving device (e.g., network entity 105). For example, the receiving device may perform reception according to multiple receiving directions by: receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receiving beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receiving beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned along 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 other acceptable signal quality based on listening according to multiple beam directions).

[0102] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. The RLC layer may perform packet segmentation and reassembly to communicate via logical channels. The MAC layer may perform priority processing and multiplexing of logical channels into transport channels. The MAC layer may also implement error detection techniques, error correction techniques, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer may provide the establishment, configuration, and maintenance of an RRC connection that supports a radio bearer for user plane data between the UE 115 and the network entity 105 or the core network 130. The PHY layer may map a transport channel to a physical channel.

[0103] UE 115 and network entity 105 may support retransmission of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data via a communication link (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific time slot for data received in a previous symbol in the time slot. In some other examples, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0104] The network may consume a large amount of power to operate a cellular network, such as when a large number of MIMO communications are deployed. By dynamically adapting transmission parameters at a network entity 105 of a wireless communication system, network power consumption may be reduced. For example, the network entity 105 may adapt or update the number of antenna ports at the antenna of the network entity 105 or the transmit power used for downlink signals and channels. In some cases, when the resource utilization in the cell is low (e.g., utilization is less than 30%), the network entity 105 may use a smaller number of antenna ports than when the resource utilization (e.g., cell load) in the cell is high (e.g., greater than 50%). For another example, when the resource utilization is low, the network entity 105 may use a lower transmit power than when the resource utilization is high.

[0105] Some systems may support dynamic adaptation of transmit parameters at the network entity 105 in a very short time. For example, the network entity 105 may be able to dynamically adapt the transmit parameters at a TTI granularity or smaller granularity. However, such fast transmit parameter adaptation may affect the UE 115 communicating with the network entity 105. For example, the fast transmit parameter adaptation in these systems may affect UE implementation, complexity, and performance. For example, the fast transmit parameter adaptation may affect the UE time-frequency tracking loop based on the synchronization signal block (SSB) or the CSI-RS for tracking (e.g., tracking reference signal (TRS)). In some cases, the fast transmit parameter adaptation may affect other measurements, such as CSI measurements, radio resource management (RRM) measurements, radio link monitoring (RLM) measurements, and beam measurements. In addition, the UE 115 may also need to know which measurements to average and when the loop will be reset due to a transmit parameter update.

[0106] For example, the UE 115 may receive an indication of a transmission parameter configuration update via a control message such as a MAC control element or a downlink control message. The wireless communication system 100 provides a technique for a parameter switching timeline so that the UE 115 can identify when the indicated configuration is to be applied, when another new configuration can be indicated, and whether the UE 115 is to have a gap for parameter reconfiguration. The parameter switching timeline can ensure that the transmission parameters are unchanged within a certain duration or interval of the timeline to improve network power savings while maintaining UE performance and implementation complexity.

[0107] Figure 2 An example of a wireless communication system 200 supporting techniques for dynamic transmission parameter adaptation according to one or more aspects of the present disclosure is illustrated. The wireless communication system 200 may include a UE 115-a and a network entity 105-a, which may be as described in reference Figure 1 Corresponding examples of UE 115 and network entity 105 are described.

[0108] The network entity 105-a may support dynamic transmission parameter adaptation to update the transmission parameters at the network entity 105-a and reduce network-side power consumption. For example, the network entity 105-a may change the number of antenna ports used by the network entity 105-a, or the network entity 105-a may change the transmission power used for downlink signaling or downlink channels.

[0109] The wireless communication system 200 may support a parameter switching timeline for dynamic transmission parameter adaptation. For example, the UE 115-a may be configured to switch between transmission parameter sets, and may switch between these sets according to the parameter switching timeline. The parameter switching timeline may include a set of timers or durations, which include a transient time, a parameter reconfiguration gap, and a time until the next parameter indication is sent. The transient time may correspond to the time from receiving a configuration update indication to applying the indicated configuration. The parameter reconfiguration gap may correspond to the gap between applying the original configuration and applying the updated configuration, which may provide the UE 115-a with time to switch between configurations. The time until the next parameter indication is sent may be, for example, the shortest duration between sending parameter updates. Reference Figure 3 Additional details and examples of this parameter switching timeline are described in more detail.

[0110] In some examples, the parameter switching timeline may be based on the capabilities of UE 115-a. For example, UE 115-a may send a capabilities message 205 to network entity 105-a. In some cases, UE 115-a or network entity 105-a or both may be configured with multiple parameter switching timelines, and UE 115-a may send the capabilities message 205 indicating which of the multiple parameter switching timelines are supported by UE 115-a. For example, the capabilities message 205 may indicate support for one or more of a plurality of pre-configured parameter switching timelines.

[0111] Additionally or alternatively, UE 115-a may send a capability message 205 indicating a value or value range for a parameter for a parameter switching timeline. For example, UE 115-a may indicate supported transient time durations, supported parameter reconfiguration gap durations, supported times between parameter update indications (e.g., a supported minimum time), or any combination thereof.

[0112] In some examples, UE 115-a may indicate to network entity 105-a the ability of UE 115-a to support dynamic transmit parameter adaptation, such as supporting dynamic antenna port adaptation or dynamic transmit power adaptation or both. In an example, UE 115-a may indicate via capability message 205 or separately indicate support for dynamic transmit parameter adaptation. In some examples, when supporting dynamic antenna port adaptation or dynamic transmit power adaptation, UE 115-a may indicate the ability to include at least one or more parameters in the switching timeline parameter. For example, UE 115-a may indicate the supported minimum time from the next transmission parameter (e.g., for antenna port adaptation or transmit power adaptation or both), the supported parameter reconfiguration gap, the supported transient time, or any combination thereof. UE capabilities may be indicated by UE 115, by frequency band, by frequency band combination, by frequency range (e.g., frequency range 1, frequency range 2, etc.), or by any combination thereof. In some examples, the reconfiguration gap may be included in the transient time or may be separated from the transient time. The UE 115 - a may indicate via the capability message 205 whether the UE 115 - a supports the reconfiguration gap to be included in the transient time or separate from the transient time.

[0113] The network entity 105-a may send an indication of a transmit parameter set 210 to the UE 115-a. For example, the UE 115-a may receive control signaling indicating a plurality of transmit parameter sets associated with a dynamic transmit parameter adaptation. In some examples, switching may be performed between the plurality of transmit parameter sets based on the dynamic transmit parameter adaptation. For example, a first transmit parameter set may include a first transmit power or a first number of antenna ports, and a second transmit parameter set may include a second transmit power or a second number of antenna ports.

[0114] UE 115-a and network entity 105-a may communicate according to a first set of parameters. For example, network entity 105-a may transmit to UE 115-a using a first transmit power for downlink signaling. Network entity 105-a may send an update indication 215 to switch from communicating with network entity 105-a according to the first set of transmit parameters (e.g., one of the plurality of sets of transmit parameters) to communicating with network entity 105-a according to a second set of transmit parameters (e.g., one of the plurality of sets of transmit parameters).

[0115] The network entity 105-a may send control signaling to the UE 115-a including the update indication 215. For example, the network entity 105-a may send the update indication 215 via a MAC control element or via downlink control information.

[0116] UE 115-a may receive an update indication 215 and determine a timer and duration for the parameter switching timeline based on the update indication 215. For example, UE 115-a may determine a start time (e.g., a start symbol or a start time slot) of a transient time and a time until the next indication update. In some examples, if the indication is sent via downlink control information, the start time of the transient time and the time until the next indication update may be based on the end of the last symbol of a configured control resource set, in which the UE 115-a receives a downlink control channel carrying the indication. In some examples, if the indication is received via a MAC control element, the start time of the transient time and the time until the next indication update may be based on a time slot, within which, in response to a downlink shared channel message (e.g., PDSCH) including the MAC control element, UE 115-a sends a feedback message (e.g., HARQ confirmation feedback) via an uplink control channel (e.g., PUSCH). Additionally or alternatively, the start time may be explicitly indicated to UE 115-a, such as via an RRC message, a MAC control element, or a DCI.

[0117] In some examples, UE 115-a may communicate according to the first set of transmit parameters during the transient time. During the reconfiguration gap, UE 115-a may switch to the second set of transmit parameters. In some examples, the reconfiguration gap may be included as part of the transient time, or the reconfiguration gap may be after the transient gap. The reconfiguration gap may enable UE 115-a to re-tune or modify radio frequency components according to the second set of transmit parameters.

[0118] After switching from the first set of transmit parameters to the second set of transmit parameters, UE 115-a and network entity 105-a may communicate according to the second set of transmit parameters. For example, UE 115-a may receive data message 220-a from network entity 105-a according to the second set of transmit parameters. For example, network entity 105-a may send data message 220-a to UE 115-a using the second transmit power. In some examples, UE 115-a may send data message 220-b to network entity 105-a according to the second set of transmit parameters.

[0119] Figure 3 An example of a parameter switching timeline 300 supporting techniques for dynamic transmission parameter adaptation according to one or more aspects of the present disclosure is illustrated. The parameter switching timeline 300 may be as shown in FIG. Figure 1 and Figure 2 The UE 115 or the network entity 105 or both implement it.

[0120] The network entity 105 may support dynamic transmission parameter adaptation to reduce power consumption on the network side. The network entity 105 may send a configuration update indication 305-a to the UE 115 to instruct the UE 115 to switch from communicating according to a first set of transmission parameters to communicating according to a second set of transmission parameters. The UE 115 and the network entity 105 may switch the transmission parameter set according to the parameter switching timeline 300.

[0121] Parameter switching timeline 300 may include or be based on a timeline parameter set. The timeline parameter set may include a reconfiguration gap 310, a transient time 315, and a time until next update indication 320. Reconfiguration gap 310 may be a time gap (e.g., a length of time, an amount of time, a duration) during which UE 115 retunes one or more radio frequency components to switch from operating with the first parameter set to operating with the second parameter set.

[0122] The transient time 315 may correspond to the duration between receiving the configuration update indication 305-a and applying the second set of parameters. In some examples, the UE 115 may be configured to communicate according to the first set of transmission parameters or the second set of transmission parameters during the transient time 315. For example, after the transient time 315, the UE 115 may apply or begin to communicate according to the second set of transmission parameters. Additionally or alternatively, the UE 115 may avoid performing some communications (e.g., monitoring downlink messages or sending uplink messages or both) during the transient time 315.

[0123] The time 320 until the next update indication may correspond to a (e.g., minimum) time defined after receiving the configuration update indication 305-a until receiving the next configuration update indication (e.g., configuration update indication 305-b). In some cases, the time 320 until the next update indication may be indicated to the UE 115 to reduce monitoring of the configuration update indication 305. For example, the UE 115 may begin monitoring the configuration update indication 305 after the time 320 until the next update indication expires. For example, from receiving the configuration update indication 305-a to the time 320 until the next update indication expires, the UE 115 may not monitor the configuration update indication 305-b during this period, thereby reducing power consumption at the UE 115.

[0124] The start time of the transient time 315 and the start time of the time until the next update indication 320 may be based on how the UE 115 receives the configuration update indication 305-a. For example, if the configuration update indication 305-a is received in a downlink control message via a downlink control channel, the start time and time 320 of the transient time 315 may be based on the last symbol of the configured control resource set of the downlink control channel. If the configuration update indication 305-a is received in a MAC control element (e.g., via a downlink shared channel), the start time and time 320 of the transient time 315 may be based on the time slot in which the UE 115 transmits the feedback message in response to the downlink shared channel carrying the MAC control element.

[0125] The transient time 315, the reconfiguration gap 310, and the time until the next update indication 320 may be defined or configured according to a certain number of symbols, time slots, frames, or any combination thereof. For example, the transient time 315 may be a certain number of symbols, time slots, or frames. In some examples, the number of TTIs that last may be related to the first subcarrier spacing of the channel carrying the configuration update indication 305-a. For example, the number of TTIs may be based on the subcarrier spacing of the physical channel (e.g., physical downlink control channel, physical downlink shared channel, SSB, etc.) sent by the network entity 105 to carry the configuration update indication 305-a. In some examples, the number of TTIs that last may be related to the subcarrier spacing of the channel configured at the UE 115. In some examples, the number of TTIs that last may be related to a fixed or pre-configured subcarrier spacing, which may be indicated to the UE 115 via control signaling or pre-configured for the wireless communication system including the UE 115.

[0126] In some examples, the reconfiguration gap 310 may be included in the transient time 315, or may occur after the transient time 315 and before the indicated parameters are applied. In a first example, the reconfiguration gap 310 may occur after the transient time 315-a and before the configuration indicated by the configuration update indication 305-a is applied. In a second example, the reconfiguration gap 310 may be included in the transient time 315-b. After the reconfiguration gap 310, the UE 115 may communicate with the network entity 105 according to the second set of parameters.

[0127] In some cases, UE 115 may not be scheduled for downlink signaling or uplink signaling, or both, during reconfiguration gap 310. In some cases, UE 115 may not expect to be scheduled for downlink signaling or uplink signaling, or both, during reconfiguration gap 310. If UE 115 is scheduled or preconfigured for uplink signaling or downlink signaling, or both, during reconfiguration gap 310, UE 115 may discard the scheduled signaling.

[0128] In some examples, UE 115 may be scheduled or preconfigured for signaling during transient time 315. For example, UE 115 may be scheduled to send an uplink message during transient time 315, or may be scheduled to receive a downlink message during transient time 315. In some examples, UE 115 may perform scheduled or preconfigured signaling during transient time 315. For example, UE 115 may receive a downlink message or send an uplink message during transient time 315. In some examples, UE 115 may send a scheduled or preconfigured uplink message during transient time 315, but UE 115 may not monitor or may discard a scheduled or preconfigured downlink message during the transient time. In some examples, UE 115 may discard a scheduled or preconfigured uplink message during transient time 315, but UE 115 may monitor or may receive a scheduled or preconfigured downlink message during the transient time. In some examples, UE 115 may not perform scheduled or pre-configured signaling during transient time 315. In some cases, UE 115 may be pre-configured for signaling during transient time 315 if UE 115 was scheduled for a time slot or symbol that overlaps with transient time 315 prior to receiving configuration update indication 305-a. For example, the schedule may be provided to UE 115 prior to UE 115 receiving the transmit parameter reconfiguration indication.

[0129] Figure 4An example of a process flow 400 that supports techniques for dynamic transmission parameter adaptation in accordance with one or more aspects of the present disclosure is illustrated. The process flow 400 may be implemented by a UE 115-b or a network entity 105-b, or both, which may be respective examples of a UE 115 and a network entity 105 as described herein.

[0130] In some examples, UE 115-a may send a capability message indicating one or more capabilities of UE 115-b at 405. For example, UE 115-b may send control signaling indicating UE capabilities associated with a parameter switching timeline. Based on the reported UE capabilities, network entity 105-b and UE 115-b may each identify the parameter switching timeline for dynamic transmission parameter adaptation. For example, the capability message may indicate the parameter switching timeline or the value of the parameter of the parameter switching timeline, and network entity 105-b and UE 115-b may perform dynamic transmission parameter adaptation according to the indicated parameter switching timeline or the value of the parameter of the parameter switching timeline.

[0131] For example, a first time gap (e.g., a reconfiguration gap) for switching between the first transmission parameter set and the second transmission parameter set, a second time gap (e.g., a transient time) from receiving the indication to applying the second transmission parameter set, and a third time gap between indications of switching transmission parameter sets (e.g., the time between supported update indications), or any combination thereof, may be included in a preconfigured and / or standardized parameter switching timeline. The UE 115-b may send control signaling indicating whether the UE supports the preconfigured and / or standardized parameter switching timeline. In some cases, the UE 115-b may send the control signaling indicating a set of supported parameter switching timelines (e.g., from a plurality of preconfigured and / or standardized parameter switching timelines). Additionally or alternatively, the UE 115-b may send the control signaling indicating a parameter switching timeline in a set of parameter switching timelines (e.g., from a plurality of preconfigured and / or standardized parameter switching timelines). In some cases, the UE 115-b may send the control signaling indicating parameters of supported parameter switching timelines. For example, UE 115-b may send control signaling indicating a supported first time gap (e.g., a supported reconfiguration gap) for switching between the first set of transmission parameters and the second set of transmission parameters, a supported second time gap (e.g., a supported transient time) from receiving the indication to applying the second set of transmission parameters, and a supported third time gap between indications of switching transmission parameter sets (e.g., a time between supported update indications), or any combination thereof. The supported time gap may refer to a time length, a duration, a shortest interval time, a longest interval time, etc.

[0132] At 410, the network entity 105-b may send, and the UE 115-b may receive, a message indicating a set of transmit parameters for dynamic transmit parameter adaptation. For example, the UE 115-b may receive a first control message indicating a plurality of sets of transmit parameters associated with the dynamic transmit parameter adaptation. For example, the first set of transmit parameters may include a first downlink transmit power or a first number of antenna ports for downlink signaling at the network entity 105-b, and the second set of transmit parameters may include a second downlink transmit power (e.g., different from the first downlink transmit power) or a second number of antenna ports (e.g., different from the first number of antenna ports).

[0133] UE 115-b and network entity 105-b may communicate according to the first set of transmission parameters. For example, network entity 105-b may use the first transmission power or use the first number of antenna ports to send a downlink signal or a downlink channel to UE 115-b. In some cases, in order to reduce power consumption on the network side, network entity 105-b may change or adapt the transmission parameters to become the second set of transmission parameters.

[0134] At 415, network entity 105-b may send, and UE 115-b may receive, a configuration update indication to switch from the first set of transmit parameters to the second set of transmit parameters. For example, UE 115-b may receive a second control message including an indication to switch from communicating with the network entity 105-b according to a first set of transmit parameters in the plurality of sets of transmit parameters to communicating with the network entity 105-b according to a second set of transmit parameters in the plurality of sets of transmit parameters. In some examples, UE 115-b may receive downlink control information including the indication to switch parameter sets. In some examples, UE 115-b may receive a MAC control element including the indication to switch parameter sets.

[0135] In some cases, UE 115-b may average or combine the measurements at the end of the period of using the first set of transmission parameters. For example, based on receiving the configuration update indication at 415, UE 115-b may begin averaging or combining the measurements obtained while communicating according to the first set of transmission parameters before switching to the second set of transmission parameters. This may provide accurate and reliable measurements for communicating according to the first set of transmission parameters without requiring measurements to be taken while communicating according to the second set of transmission parameters.

[0136] At 420, UE 115-b may switch the transmit parameter set. For example, UE 115-b may switch from the first transmit parameter set to the second transmit parameter set according to a parameter switching timeline. The parameter switching timeline may include a first time gap (e.g., a reconfiguration gap) for switching between the first transmit parameter set and the second transmit parameter set, a second time gap (e.g., a transient time or transition time) from receiving the configuration update indication to applying the second transmit parameter set, and a third time gap between indications of switching transmit parameter sets.

[0137] During the first time gap (e.g., the reconfiguration gap), UE 115-b may modify the configuration at UE 115-b to communicate according to the second set of transmission parameters. For example, UE 115-b may re-tune the RF component of UE 115-b to receive downlink signaling according to the second set of transmission parameters.

[0138] During the second time gap (e.g., transient time), UE 115-b may (e.g., may be configured to) communicate or discard scheduled signaling. For example, UE 115-b may have received the configuration update indication and identified the second set of transmission parameters, but UE 115-b may or may not apply the second set of transmission parameters to the communication with network entity 105-b. In some examples, UE 115-b may perform scheduled or pre-configured uplink or downlink signaling during the second time gap. In some examples, UE 115-b may perform scheduled or pre-configured uplink signaling, but may not perform scheduled or pre-configured downlink signaling, or vice versa. In some examples, UE 115-b may not perform (e.g., may discard) scheduled or pre-configured uplink or downlink signaling during the second time gap. In some cases, UE 115-b may perform scheduled signaling based on the first set of transmission parameters. In some other examples, UE115-b may perform scheduling or preconfigured signaling based on the second set of transmission parameters.

[0139] At 425, the UE 115-b and the network entity 105-b may communicate according to the second set of transmit parameters. For example, the UE 115-b and the network entity 105-b may communicate one or more messages based on the switch from the first set of transmit parameters to the second set of transmit parameters in response to the second control message according to the parameter switching timeline for the dynamic transmit parameter adaptation. For example, the network entity 105-b may send downlink signaling or a downlink channel to the UE 115-b using the second transmit power or using the second number of antenna ports.

[0140] Figure 5A block diagram 500 of a device 505 supporting techniques for dynamic transmission parameter adaptation according to one or more aspects of the present disclosure is shown. The device 505 can be an example of aspects of the UE 115 as described herein. The device 505 may include a receiver 510, a transmitter 515, and a communication manager 520. The device 505 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0141] The receiver 510 may provide means for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to techniques for dynamic transmission parameter adaptation). The information may be communicated to other components of the device 505. The receiver 510 may utilize a single antenna or a collection of multiple antennas.

[0142] The transmitter 515 may provide means for transmitting signals generated by other components of the device 505. For example, the transmitter 515 may transmit information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to techniques for dynamic transmission parameter adaptation). In some examples, the transmitter 515 may be co-located with the receiver 510 in a transceiver module. The transmitter 515 may utilize a single antenna or a collection of multiple antennas.

[0143] The communication manager 520, the receiver 510, the transmitter 515, or various combinations thereof, or various components thereof, may be examples of means for performing aspects of the techniques for dynamic transmission parameter adaptation as described herein. For example, the communication manager 520, the receiver 510, the transmitter 515, or various combinations thereof, or components thereof, may support methods for performing one or more of the functions described herein.
