[0054] In some wireless communications systems, a network entity can perform various operations in order to enable network energy savings (NES). For example, a network entity can implement a cell discontinuous reception (DRX) cycle, implement a cell discontinuous transmission (DTX) cycle, and other operations to support NES. However, in order to implement a reduced amount of power consumption at the network entity, it can be desirable for the network entity to implement various resource adaptations.
[0055] The techniques described herein can enable network entities and UEs to efficiently perform physical uplink control channel (PUCCH) power adaptation, which can promote reduced power consumption at the network entity. For example, a network entity can transmit first control signaling (e.g., such as radio resource control (RRC) signaling) indicating a first set of PUCCH resource occasions and a second set of PUCCH resource occasions for a UE to use. The UE can use resource occasions in the first set of PUCCH resource occasions to transmit one or more uplink messages, where the first set of PUCCH resource occasions can otherwise be referred to as a default set of PUCCH resource occasions. The UE can switch from using resource occasions in the first set of PUCCH resource occasions to using resource occasions in the second set of PUCCH resource occasions based on second control signaling (e.g., downlink control information (DCI) from the network entity or uplink control information (UCI) communicated from the UE).
[0056] In such examples, the first set of PUCCH resource occasions can have fewer resource occasions relative to those in the second set of PUCCH resource occasions, enabling the network entity to conserve power when the UE is operating in the first set of PUCCH resource occasions. Alternatively, the second set of PUCCH resource occasions can have fewer resource occasions relative to those in the first set of PUCCH resource occasions. As such, the network entity or the UE can indicate to switch to using the second set of PUCCH resource occasions during times of relatively low traffic between the UE and the network entity, reducing power consumption at the network entity. In some other examples, the second set of PUCCH resource occasions can be an empty set. As such, by switching from operating in the first set of PUCCH resource occasions to operating in the second set of PUCCH resource occasions, the UE can skip transmitting one or more uplink messages, enabling the network entity to avoid monitoring for such uplink messages and conserve power.
[0057] Aspects of the disclosure are first described in the context of a wireless communications system. Aspects of the disclosure are further described in the context of state diagrams, timing diagrams, and process flows. Aspects of the disclosure are further exemplified by apparatus diagrams, system diagrams, and flowcharts relating to techniques for PUCCH adaptation, and aspects of the disclosure are described with reference to these diagrams.
[0058] FIG. 1An example of a wireless communications system 100 that supports techniques for PUCCH adaptation is shown, in accordance with one or more aspects of the present disclosure. The wireless communications system 100 can include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 can be a Long Term Evolution (LTE) network, a LTE-Advanced (LTE-A) network, a LTE-A Pro network, a New Radio (NR) network, or a network operating according to some other wireless standard, including future iterations of the wireless standards explicitly mentioned herein and wireless standards not explicitly mentioned herein.
[0059] The network entities 105 can be dispersed throughout the geographic region of the wireless communications system 100, and can each include devices in different forms or having different capabilities. In various examples, the network entities 105 can 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 UEs 115 can wirelessly communicate via one or more communication links 125, such as radio frequency (RF) access links. For example, a network entity 105 can support a coverage area 110 (e.g., a geographic coverage area) within which UEs 115 and the network entity 105 can establish one or more communication links 125. The coverage area 110 can be an example of a geographic area over which a network entity 105 and a UE 115 can support signal communication in accordance with one or more radio access technologies (RATs).
[0060] The UEs 115 can be dispersed throughout the coverage areas 110 of the wireless communications system 100, and each UE 115 can be stationary or mobile, or both at different times. The UEs 115 can be devices in different forms or having different capabilities. FIG. 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein can be able to communicate with various types of devices, such as other UEs 115 or network entities 105, as shown in FIG. 1. FIG. 1 The UEs 115 described herein can be able to communicate with various types of devices, such as other UEs 115 or network entities 105, as shown in FIG. 1.
[0061] As described herein, a node of the wireless communications system 100, which can be referred to as a network node or a wireless node, can be a network entity 105 (e.g., any of the network entities described herein), a UE 115 (e.g., any of the UEs described herein), a network controller, a device, an apparatus, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node can be a UE 115. As another example, a node can be a network entity 105. As yet another example, a first node can be configured to communicate with a second node or a third node. In one aspect of this example, the first node can be a UE 115, the second node can be a network entity 105, and the third node can be a UE 115. In another aspect of this example, the first node can be a UE 115, the second node can be a network entity 105, and the third node can be a network entity 105. In other aspects of this example, the first node, the second node, and the third node can be different relative to these examples. Similarly, references to a UE 115, a network entity 105, a device, an apparatus, a computing system, etc. can include the disclosure of the UE 115, the network entity 105, the device, the apparatus, the computing system, etc. as a node. For example, a disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
[0062] In some examples, the network entities 105 can be in communication with the core network 130 or with each other or both. For example, the network entities 105 can communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to an SI, N2, N3, or other interface protocol). In some examples, the network entities 105 can communicate with each other via backhaul communication links 120 (e.g., according to an X2, Xn, or other interface protocol) either directly (e.g., direct point-to- point between network entities 105) or indirectly (e.g., via core network 130). In some examples, the network entities 105 can communicate with each other via mid-cell communication links 162 (e.g., according to a mid-cell interface protocol) or front-haul communication links 168 (e.g., according to a front-haul interface protocol), or any combination thereof. The backhaul communication links 120, the mid-cell communication links 162, or the front-haul communication links 168 can be or include one or more wired links (e.g., electrical, fiber optic), one or more wireless links (e.g., radio, wireless optical), etc., or various combinations thereof. A UE 115 can communicate with the core network 130 via communication links 155.
[0063] One or more of the network entities 105 described herein can include or can 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 NodeB, an evolved NodeB (eNB), a Next Generation NodeB or a Gigabit NodeB (any of which can be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a Home NodeB, a Home eNodeB, or other suitable terminology). In some examples, the network entity 105 (e.g., base station 140) can be implemented in an aggregated (e.g., monolithic, self-standing) base station architecture that can be configured to utilize protocol stacks that are physically or logically integrated within a single network entity 105 (e.g., a single RAN node such as a base station 140).
[0064] In some examples, the network entity 105 can be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that can be configured to utilize protocol stacks that are 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 can include one or more of 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 can also be referred to as a radio head, an intelligent radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmission reception point (TRP). One or more components of the network entity 105 in the disaggregated RAN architecture can be co-located, or one or more components of the network entity 105 can be in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the disaggregated RAN architecture can be implemented as virtual units (e.g., a virtual CU (VCU), a virtual DU (VDU), a virtual RU (VRU)).
[0065] The functional split between the CU 160, the DU 165, and the RU 170 is flexible and can 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 the CU 160, the DU 165, or the RU 170. For example, a functional split of a protocol stack can be employed between the CU 160 and the DU 165, such that the CU 160 can support one or more layers of the protocol stack, and the DU 165 can support one or more different layers of the protocol stack. In some examples, the CU 160 can 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 can connect to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 can host lower protocol layers, such as Layer 1 (LI) (e.g., Physical (PHY) layer) or L2 (e.g., Radio Link Control (RLC) layer, Medium Access Control (MAC) layer) functionality and signaling, and can each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of a protocol stack can be employed between the DU 165 and the RU 170, such that the DU 165 can support one or more layers of the protocol stack, and the RU 170 can support one or more different layers of the protocol stack. The DU 165 can support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between the CU 160 and the DU 165 or between the DU 165 and the RU 170 can be within a protocol layer (e.g., some functions of a protocol layer can be performed by one of the CU 160, the DU 165, or the RU 170, while other functions of that protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170). The CU 160 can be further split in functionality into CU control plane (CU-CP) and CU user plane (CU-UP) functions. The CU 160 can connect to one or more DUs 165 via a backhaul communication link 162 (e.g., Fl, Fl-c, Fl-u), and the DU 165 can connect to one or more RUs 170 via a front-haul communication link 168 (e.g., open front-haul (FH) interface). In some examples, the backhaul communication link 162 or the front-haul communication link 168 can be implemented according to an interface (e.g., channel) between layers of a protocol stack that are supported by the respective network entities 105 that communicate via these communication links.
[0066] In some wireless communications systems (e.g., wireless communications system 100), infrastructure and spectrum resources for radio access can support wireless backhaul link capabilities to supplement wired backhaul connections to provide 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) can be partially controlled by one another. One or more IAB nodes 104 can be referred to as a donor entity or IAB donor. One or more DUs 165 or one or more RUs 170 can be partially controlled by one or more CUs 160 associated with a donor network entity 105 (e.g., a donor base station 140). One or more donor network entities 105 (e.g., IAB donors) can 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). An IAB node 104 can include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a coupled DU 165 of an IAB donor. The IAB-MT can include a separate set of antennas for relaying communications with UEs 115 or can share the same antennas (e.g., of an RU 170) of the IAB node 104 for accessing via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, an IAB node 104 can include a DU 165 that supports a communication link with an additional entity (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of an access network. In such cases, one or more components of the disaggregated RAN architecture (e.g., one or more IAB nodes 104 or components of an IAB node 104) can be configured to operate according to the techniques described herein.
[0067] In cases where the techniques described herein apply in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture can be configured to support techniques for PUCCH adaptation as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., base station 140) can additionally or alternatively be performed by one or more components of the disaggregated RAN architecture (e.g., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).
[0068] A UE 115 can include or can be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” can also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 can also include or can 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, a UE 115 can include or can 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 communications (MTC) device, among other examples, which can be implemented in various objects such as appliances or vehicles, among other examples.
[0069] The UEs 115 described herein can be able to communicate with various types of devices, such as other UEs 115 that can sometimes act as relays or FIG. 1 as shown.
[0070] The UEs 115 and the network entities 105 can wirelessly communicate with each other using resources associated with one or more carriers via one or more communication links 125 (e.g., access links). The term “carrier” can refer to a set of RF spectrum resources having a defined physical layer structure for supporting communication links 125. For example, a carrier used for a communication link 125 can include a portion of an RF spectrum band (e.g., a bandwidth part (BWP)) operating according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel can carry acquisition signaling (e.g., synchronization signals, system information), control signaling (e.g., control channels), user data (e.g., data channels), or other signaling. The wireless communications system 100 can support communication with a UE 115 using carrier aggregation or multi-carrier operation. According to a carrier aggregation configuration, a UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used for both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) component carriers. Communications between a network entity 105 and other devices can refer to communications between these devices and any portion of the network entity 105 (e.g., an entity, a sub-entity). For example, the terms “transmit,” “receive,” or “communicate” can refer to any portion of the network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) communicating with another device (e.g., directly or via one or more other network entities 105).
[0071] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, 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 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 decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high-order modulation scheme can correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources can increase the data rate or data integrity used for communication with UE 115.
[0072] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period T. s =1 / (Δf) max ·N f ) seconds, where Δf max This can represent the supported subcarrier spacing, while N f The supported Discrete Fourier Transform (DFT) size can be represented. The time interval of the communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).
[0073] 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, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into a 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 number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple 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) symbols. f The duration of a symbol period is associated with a ( ) sampling period. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.
[0074] A subframe, a slot, a mini-slot, or a symbol can be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and can 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) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communications system 100 (e.g., in the time domain) can be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs)).
[0075] Physical channels can be multiplexed according to various techniques to communicate using a carrier. For example, physical control channels and physical data channels can be multiplexed for transmission via a downlink carrier using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel can be defined by a collection of time and frequency resources on which control information is to be conveyed. A control region can extend over several symbol periods and frequency resources. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more of the UEs 115 can monitor or search control regions according to one or more search space sets to obtain control information, and each search space set can include one or more control channel candidates arranged in an aggregation level of one or more of a cascade of control channel candidates. An aggregation level of a control channel candidate can refer to a quantity of control channel resources (e.g., control channel elements (CCEs)) associated with encoded information for a control information format having a given payload size. Search space sets can include common search space sets configured for transmission of control information to a plurality of UEs 115, and UE-specific search space sets for transmission of control information to a specific UE 115.
[0076] In some examples, network entities 105 (e.g., base stations 140, RUs 170) can be mobile and thus provide communication coverage for a moving coverage area 110. In some examples, different coverage areas 110 associated with different technologies can overlap, but different coverage areas 110 can be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies can be supported by different network entities 105. Wireless communications system 100 can 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.
[0077] The wireless communications system 100 can be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 can be configured to support ultra-reliable low-latency communications (URLLC). The UEs 115 can be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communications can include private communication or group communication, and can be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions can include prioritization of services, and such services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency can be used interchangeably herein.
[0078] In some examples, UEs 115 can be configured to communicate directly with other UEs 115 via device-to-device (D2D) communication links 135 (e.g., according to a peer-to-peer (P2P) or D2D or sidelink protocol). In some examples, one or more UEs 115 in a group that is performing D2D communication can be within the coverage area 110 of a network entity 105 (e.g., base station 140, RU 170), which can support D2D communication for such a group configured (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 in such a group can be outside the coverage area 110 of a network entity 105 or can otherwise be unable to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communications can support a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, a network entity 105 can facilitate scheduling of resources for D2D communications. In some other examples, D2D communications can be carried out between UEs 115 without the involvement of a network entity 105.
[0079] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an evolved packet core (EPC) or 5G core (5GC), which can include at least one control plane entity that can manage access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that can route packets or interconnect to external networks (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity can manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for UEs 115 served by network entities 105 associated with the core network 130. User IP packets can be transferred through the user plane entity, which can provide IP address allocation as well as other functions. The user plane entity can be connected to the IP services 150 of the one or more network operators. The IP services 150 can include access to the Internet, Intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.
[0080] The wireless communications system 100 can operate using one or more frequency bands, in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). The region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band, since the wavelengths range from approximately one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features, but the waves can penetrate structures sufficiently for a macro cell to provide service to UEs 115 located indoors. The use of UHF frequencies typically requires a higher site density than frequencies that fall in lower frequency bands, such as high frequency (HF) or very high frequency (VHF) parts of the spectrum. However, UHF waves can experience less attenuation than waves that operate at higher frequencies such as SHF or EHF. The use of devices that operate at these higher frequencies can be associated with a smaller antenna size, which can enable a higher site density for a given overall area.
[0081] The wireless communications system 100 can utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 can employ LTE License Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed frequency spectrum band such as the 5 GHz industrial, scientific and medical (ISM) band. When operating in unlicensed frequency spectrum bands, access points 105 and UEs 115 such as network entities 105 and UE 115 can employ carrier sensing for collision detection and avoidance. In some examples, operations in unlicensed frequency spectrum bands can be based on carrier aggregation configurations in combination with operations in licensed frequency spectrum bands (e.g., LAA). Operations in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0082] The network entity 105 (e.g., base station 140, RU 170) or UE 115 can be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the network entity 105 or UE 115 can be located within one or more antenna arrays or antenna panels, which can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays can be collocated together, such as in a antenna assembly, for example, at an antenna tower. In some examples, the antennas associated with the network entity 105 can be located at different geographic locations. The network entity 105 can include an array of antennas with a set of multiple rows and multiple columns of antenna ports that the network entity 105 can use for beamforming to support communication with UE 115. Likewise, a UE 115 can include one or more antenna arrays, which can support various MIMO or beamforming operations. Additionally or alternatively, an antenna panel can support RF beamforming for signals transmitted via the antenna ports.
[0083] Beamforming, which can also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer the beam over the space. Beamforming can be achieved by combining the signals communicated by antennas of an antenna array such that some signals are amplified while others are attenuated, which can be done in such a way that the amplified signals appear to come from a single direction. The adjustments to the signals by the transmitting or receiving device can include amplifying the signals with a phase and / or amplitude adjustment, which can be performed for signals communicated by each of the antennas of the antenna array. The adjustments associated with each antenna can be defined by a beamforming weight set associated with an orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).
[0084] In some cases, the network entity 105 can operate in an NES mode in order to conserve network energy during transmission and reception of various messages with the UE 115. For example, to reduce power consumption, the network entity 105 can implement a cell DRX cycle (e.g., which can be defined from the perspective of the network entity 105). In such a cell DRX cycle, the network entity 105 can reduce reception activity (e.g., reception of uplink messages 225) by limiting transmission of one or more uplink messages 225 from the UE 115 to be during a cell DRX on-duration. Similarly, the network entity 105 can implement a cell DTX cycle in order to reduce power consumption at the network entity by limiting transmission activity (e.g., transmission of one or more downlink messages) from the network entity 105 to the UE 115 to be during a cell DTX on-duration.
[0085] In such cases, the UE 115 can receive an indication of the cell DRX and DTX on- and off-durations, such that the UE 115 can align one or more of a UE DRX cycle, a semi-persistent scheduling physical downlink shared channel (PDSCH), a channel state information (CSI) reference signal (CSI-RS) reception cycle, etc., with the cell DTX and cell DRX on- and off-durations, such that the UE 115 can also conserve power by not activating a receiver at the UE 115.
[0086] In some cases, the network entity 105 can align transmission and reception of the wireless transceiver of the network entity 105 in order to achieve increased power saving gains. That is, the network entity 105 can align a cell DTX cycle with a cell DRX cycle, such that the network entity 105 can experience increased power savings. For example, when both a transmitter of the network entity 105 and a receiver of the network entity 105 are off, the network entity 105 can be able to turn off one or more components, such as a high-speed clock or a baseband component. As such, the network entity 105 can align the cell DRX cycle and the cell DTX cycle to achieve such a result.
[0087] In some cases, the UE 115 and the network entity 105 can support an indication of unused configured grant physical uplink shared channel (PUSCH) resources to enhance configured grants with multiple PUSCHs and reduce power consumption at the network entity 105. That is, the UE 115 and the network entity 105 can support dynamic indication of unused configured grant PUSCH resource occasions based on UCI transmitted for the UE 115 (e.g., configured grant UCI or UCI configured to indicate unused PUSCH resource occasions).
[0088] For example, the network entity 105 can transmit a message to the UE 115 including a configured grant for one or more PUSCH resource occasions. Such configured grant PUSCH resources can be an example of periodic uplink transmission opportunities for the UE 115. As such, if there is uplink data in the buffer of the UE 115, the UE 115 can transmit the data via the resource occasions of the configured grant PUCCH resources (e.g., the allocated resources). The UE 115 can perform such operations in cases where the uplink data has a variable instantaneous data generation rate. Otherwise, if there is no data in the buffer of the UE 115, the UE 115 can skip or otherwise refrain from using the configured grant PUSCH resource occasions. In such cases, the UE can transmit UCI to the network entity 105 indicating that the UE 115 will skip one or more PUSCH resource occasions.
[0089] Such skipping of configured grant PUSCH resources can be optional or based on a capability of the UE 115. In some examples, the UE 115 can transmit a capability message, where the capability message includes a skip capability parameter such as skipUplinkTxDynamic. The skipUplinkTxDynamic parameter can indicate whether the UE 115 supports skipping uplink transmissions of uplink grants indicated on a physical downlink control channel (PDCCH) in cases where no data is available for transmission (e.g., as specified in TS 38.321 of 3GPP standards).
[0090] However, in some examples, it can be desirable for the network entity 105 and the UE 115 to implement one or more additional techniques in order to improve the NES in terms of both transmission and reception at the network entity 105. For example, it can be desirable to implement more efficient operations to dynamically or semi-statically and with finer granularity adjust transmission, reception, or both in one or more of the NES techniques in the time, frequency, spatial, and power domains, and obtain potential support and feedback from the UE 115 via potential UE assistance information. Additionally, it can be desirable to implement various techniques for information exchange (e.g., coordination) via one or more network interfaces.
[0091] The techniques described herein can enable network entity 105 and UE 115 to efficiently perform PUCCH resource adaptation, which can facilitate reduced power consumption at network entity 105. For example, network entity 105 can transmit first control signaling (e.g., such as RRC signaling) indicating a first set of PUCCH resource occasions and a second set of PUCCH resource occasions for UE 115 to use. UE 115 can use resource occasions in the first set of PUCCH resource occasions to transmit one or more uplink messages, where the first set of PUCCH resource occasions can otherwise be referred to as a default set of PUCCH resource occasions. UE 115 can dynamically switch from using resource occasions in the first set of PUCCH resource occasions to using resource occasions in the second set of PUCCH resource occasions based on second control signaling (e.g., DCI from network entity 105 or UCI transmitted from UE 115).
[0092] In such examples, the first set of PUCCH resource occasions can have fewer resource occasions relative to those in the second set of PUCCH resource occasions, enabling network entity 105 to conserve power due to monitoring a relatively fewer number of resource occasions in the first set of PUCCH resource occasions. Alternatively, the second set of PUCCH resource occasions can have fewer resource occasions relative to those in the first set of PUCCH resource occasions. As such, network entity 105 or UE 115 can indicate to switch to using the second set of PUCCH resource occasions during times of relatively lower traffic between UE 115 and network entity 105, thereby reducing power consumption at network entity 105. In some other examples, the second set of PUCCH resource occasions can be an empty set. As such, by switching from operating in the first set of PUCCH resource occasions to operating in the second set of PUCCH resource occasions, UE 115 can skip transmitting one or more uplink messages, enabling network entity 105 to avoid monitoring for such uplink messages and conserve power.
[0093] FIG. 2 An example of a wireless communications system 200 that supports techniques for PUCCH adaptation is shown, in accordance with one or more aspects of the present disclosure. Aspects of wireless communications system 200 can implement, or be implemented by, aspects of wireless communications system 100. For example, wireless communications system 200 can include network entity 105 and UE 115, which can be examples of the corresponding devices described herein with reference to FIG. 1 wireless communications system 100. Network entity 105 and UE 115 can implement techniques for PUCCH adaptation in order to enable network entity 105 to reduce power consumption.
[0094] In some cases, the network entity 105 can communicate with the UE 115 via various channels. For example, the UE 115 can communicate uplink messages to the network entity 105 via a PUSCH, while the network entity 105 can communicate downlink messages to the UE 115 via a PDSCH. To facilitate uplink communications, the UE 115 can dynamically transmit a scheduling request via one or more PUCCH resource occasions 215 to initiate uplink data transmissions with the network entity 105. Similarly, to facilitate downlink communications, the network entity 105 can dynamically transmit scheduling DCI via a PDCCH resource to initiate downlink data transmissions with the UE 115. In such examples, the network entity 105 and the UE 115 can periodically monitor the PUCCH resource occasions 215 and the PDCCH resource occasions for such messages, which can increase power consumption at the network entity 105 and the UE 115.
[0095] To support reduced power consumption at the UE 115, the network entity 105 and the UE 115 can implement PDCCH monitoring adaptation to reduce PDCCH monitoring efforts by the UE 115 (e.g., to conserve power at the UE 115). In some cases, the network entity 105 and the UE 115 can support PDCCH resource occasion skipping as part of PDCCH monitoring adaptation. That is, the network entity 105 can indicate, via a PDCCH monitoring adaptation field of the scheduling DCI, for the UE 115 to stop monitoring one or more PDCCH resource occasions (e.g., PDCCH resources intended for the UE 115). As such, the UE 115 can reduce power consumption and conserve energy by refraining from monitoring the PDCCH resource occasions.
[0096] Additionally or alternatively, the network entity 105 and the UE 115 can support search space set group (SSSG) switching. In such cases, the network entity 105 can configure the UE 115 with two or more SSSGs, where each SSSG can include a varying (e.g., different) level of PDCCH monitoring effort. That is, the network entity 105 can configure the two or more SSSGs with different densities (e.g., numbers) of PDCCH resource occasions, different numbers of PDCCH resource candidates, and / or the like. As such, the network entity 105 can indicate, via a PDCCH monitoring adaptation field shared with a PDCCH skipping indication of a scheduling DCI, for the UE 115 to stop monitoring a first SSSG and switch to monitoring a second SSSG. In an example, the network entity 105 can configure the first SSSG with a sparse set (e.g., a light set) of PDCCH resource occasions relative to PDCCH resource occasions of the second SSSG. As such, when the UE 115 receives an indication to monitor PDCCH resource occasions of the first SSSG, the UE 115 can experience reduced power consumption due to monitoring a relatively fewer number of PDCCH resource occasions.
[0097] However, using current techniques, the network entity can not be able to have similar power savings as the UE 115. For example, current techniques can not enable the network entity 105 to reduce PUCCH resource occasion 215 monitoring and detection effort, resulting in increased power consumption at the network entity 105.
[0098] In some implementations, the network entity 105 and the UE 115 can implement techniques for skipping one or more PUCCH resource occasions 215, switching between PUCCH sets 210, or both, in order to reduce power consumption at the network entity 105 and conserve power at the network entity. Such operations can be triggered by the UE 115 (e.g., via a PUSCH occasion skipping indication of UCI or a separate field of UCI) or by the network entity 105 (e.g., via an indication in a scheduling DCI).
[0099] For example, the network entity 105 can configure (e.g., determine) at least PUCCH set 210-a and PUCCH set 210-b (e.g., multiple sets of PUCCH resource occasions) for use by the UE 115. In some examples, each PUCCH set 210 can include multiple PUCCH resource occasions 215. Such PUCCH sets 210 can be referred to as PUCCH resource groups (PRGs). Additionally or alternatively, each PUCCH set 210 can include multiple PUCCH sets 210, where each PUCCH set 210 of the multiple PUCCH sets can include one or more PUCCH resource occasions 215. A PUCCH set 210 that includes multiple PUCCH sets 210 can be referred to as a PUCCH resource set group (PRSG). Further, in some examples, the network entity 105 can configure a null PUCCH set 210 (e.g., a PUCCH set 210 that does not include PUCCH resource occasions 215). As such, if the UE 115 is to skip one or more PUCCH resource occasions 215, the UE 115 can switch to operating in the null PUCCH set 210, as described herein with reference to FIG. 2. FIG. 4
[0100] Based on configuring each PUCCH set 210, the network entity 105 can transmit, to the UE 115, first control signaling 205 (e.g., such as RRC signaling) indicating PUCCH set 210-a (e.g., a first set of PUCCH resource occasions) and PUCCH set 210-b (e.g., a second set of PUCCH resource occasions). In some examples, the network entity 105 can indicate that PUCCH set 210-a is a default PUCCH group. As such, the UE 115 can adopt or begin operating in PUCCH set 210-a based on receiving the first control signaling 205 (e.g., when a switch between PUCCH sets 210 is configured). In such examples, the network entity 105 can configure PUCCH set 210-a (e.g., the default PUCCH group) to have fewer PUCCH resource occasions 215 relative to those PUCCH resource occasions configured in PUCCH set 210-b. Alternatively, the network entity 105 can configure PUCCH set 210-a (e.g., the default PUCCH group) to have an increased number of PUCCH resource occasions 215 relative to those PUCCH resource occasions configured in PUCCH set 210-b.
[0101] In some examples, the UE 115 can dynamically communicate the second control signaling 220 indicating that the UE 115 is to switch from operating in the PUCCH set 210-a to operating in the PUCCH set 210-b. For example, the UE 115 can transmit the second control signaling 220-a indicating the switch from the PUCCH set 210-a to the PUCCH set 210-b, where the second control signaling 220-a can be an example of UCI. In such examples, the UE 115 can transmit the indication to switch PUCCH sets 210 via the UCI as part of the indication to skip one or more configured grant PUSCH occasions. That is, the UE 115 can piggyback the indication to switch PUCCH sets 210 in the PUSCH skipping indication of the UCI. For example, when the UE 115 transmits the indication to skip PUSCH via the second control signaling 220-a (e.g., UCI), the UE 115 can also imply that the UE 115 is to switch between PUCCH sets 210. Alternatively, the UE 115 can indicate the switch between PUCCH sets 210 (e.g., PUCCH adaptation) via a field of the UCI following the indication to skip configured grant PUSCH occasions. That is, the indication to switch between PUCCH sets 210 can be separate from the indication to skip PUSCH in the second control signaling 220 (e.g., UCI).
[0102] The UE 115 can transmit the second control signaling 220-a (e.g., UCI) indicating the switch between PUCCH sets 210 (e.g., PUCCH adaptation) based on UE traffic, a size of a buffer at the UE 115, or both. In an example, the PUCCH set 210-a can include fewer PUCCH resource occasions 215 relative to those in the PUCCH set 210-b, enabling the network entity 105 to reduce power consumption due to reduced monitoring efforts when operating in the PUCCH set 210-a. As such, in cases where the UE 115 has urgent or frequent uplink data to transmit, or in cases where the size of the buffer of the UE 115 meets a threshold, the UE 115 can transmit the second control signaling 220-a (e.g., UCI) indicating the switch to operating in the PUCCH set 210-b that includes denser PUCCH resource occasions 215.
[0103] As another illustrative example, the PUCCH set 210-a can include more PUCCH resource occasions 215 relative to those in the PUCCH set 210-b. As such, if the UE 115 has relatively less traffic or relatively less data in the buffer of the UE 115, the UE 115 can dynamically indicate, via the second control signaling 220-a (e.g., UCI), to the network entity 105 to switch to the PUCCH set 210-b, which can have sparser PUCCH resource occasions 215, enabling the network entity 105 to reduce power consumption. In this way, the UE 115 can dynamically indicate to switch between PUCCH sets 210 according to traffic at the UE 115, a buffer size of the UE 115, or both.
[0104] In some other examples, the network entity 105 can dynamically communicate the second control signaling 220 indicating that the UE 115 is to switch from operating in the PUCCH set 210-a to operating in the PUCCH set 210-b. For example, the network entity 105 can transmit the second control signaling 220-a including an indication to switch PUCCH sets 210, where the second control signaling 220-a can be a DCI. That is, the network entity 105 can include an indication to switch between PUCCH sets 210 (e.g., a PUCCH adaptation indication) via a field of the second control signaling 220-b (e.g., a DCI).
[0105] In some examples, the network entity 105 can associate a PUCCH adaptation with an indication of a PDCCH adaptation. For example, the network entity 105 can transmit the second control signaling 220-b (e.g., a DCI) indicating for the UE 115 to perform a PDCCH resource skipping (e.g., skip one or more PDCCH resource occasions). As such, based on receiving the indication to skip one or more PDCCH resource occasions, the UE 115 can skip one or more PUCCH resource occasions 215 by switching to the empty PUCCH set 210 (e.g., as referenced with respect to FIG. 2B). FIG. 4(e.g., DCI) that the UE 115 is performing PDCCH skipping, the UE 115 can also skip one or more PUCCH resource occasions 215. Similarly, the network entity 105 can associate a switch between PUCCH sets 210 with performing an SSSG switch. For example, the network entity 105 can indicate, via the second control signaling 220-b, that the UE 115 is to switch between a first SSSG and a second SSSG. As such, based on the second control signaling 220-b (e.g., DCI) indicating for the UE 115 to switch between SSSGs, the UE 115 can also switch between the PUCCH set 210-a and the PUCCH set 210-b.
[0106] In some examples, the network entity 105 can transmit the second control signaling 220-b indicating for the UE 115 to switch between PUCCH sets 210 based on traffic at the network entity according to a cell DTX and DRX cycle, or both. In this way, the network entity 105 can dynamically transmit an indication for the UE 115 to operate in sparser or denser PUCCH sets 210 in order to maintain communications in the wireless communications system 200 and reduce power consumption at the network entity 105.
[0107] In some examples, the second control signaling 220 (e.g., DCI or UCI) can include various codepoint values for indicating whether the UE 115 is to skip one or more PUCCH resource occasions 215, switch between PUCCH sets 210, or both. As exemplified in Table 1 below, a first codepoint value of the second control signaling 220 can indicate that the UE 115 is to neither skip PUCCH resource occasions 215 nor switch between PUCCH sets 210. A second codepoint value can indicate for the UE 115 to skip one or more PUCCH resource occasions 215 (e.g., switch to an empty PUCCH set 210) for a duration of a timer, which can be referred to herein with reference to FIG. 2 as PUCCH skipping. A third codepoint value can indicate for the UE 115 to switch to operating in the PUCCH set 210-a (e.g., a default PUCCH group), while a fourth codepoint value can indicate for the UE 115 to switch to operating in the PUCCH set 210-b (e.g., a non-default PUCCH group). It should be appreciated that the foregoing codepoints can not be all-inclusive, and the second control signaling 220 can include a variety of additional codepoint values to indicate various operations. FIG. 4 Further described. A third codepoint value can indicate for the UE 115 to switch to operating in the PUCCH set 210-a (e.g., a default PUCCH group), while a fourth codepoint value can indicate for the UE 115 to switch to operating in the PUCCH set 210-b (e.g., a non-default PUCCH group). It should be appreciated that the foregoing codepoints can not be all-inclusive, and the second control signaling 220 can include a variety of additional codepoint values to indicate various operations.

[0109] Table 1. Codepoint value and operation
[0110] In some other examples, the UE 115 can switch from operating in the PUCCH set 210-a to operating in the PUCCH set 210-b in response to transmitting the uplink message 225. For example, when the UE 115 is operating within the PUCCH set 210-a (e.g., a default PUCCH group), the UE 115 can switch to the PUCCH set 210-b (e.g., a non-default PUCCH group) after transmitting the uplink message 225-a via the PUCCH resource occasion 215. The network entity 105 can receive the uplink message 225-a and continue to switch from operating in the PUCCH set 210-a to operating in the PUCCH set 210-b. In this way, the UE 115 and the network entity 105 can dynamically switch between the PUCCH set 210-a (e.g., a default PUCCH group) and the PUCCH set 210-b (e.g., a non-default PUCCH group) without incurring additional signaling overhead.
[0111] The network entity 105 and the UE 115 can perform the switch from the PUCCH set 210-a to the PUCCH set 210-b according to a threshold time offset 230 (e.g., an application delay) from the second control signaling 220 or a transmission time of the uplink message 225-a. The threshold time offset 230 can be a minimum time offset between a transmission or reception time of the second control signaling 220 and a time at which the network entity 105 stops monitoring the PUCCH resource occasions 215 in the PUCCH set 210-a (e.g., an old PUCCH group) and starts monitoring the PUCCH resource occasions 215 in the PUCCH set 210-b (e.g., a new PUCCH group). Likewise, the threshold time offset 230 can be a minimum time offset between a time at which the UE 115 stops transmitting the uplink message 225 via the PUCCH resource occasions 215 in the PUCCH set 210-a and a time at which the UE 115 starts transmitting the uplink message 225 via the PUCCH resource occasions in the PUCCH set 210-b. The threshold time offset 230 can be configured by the network entity 105 via the first control signaling 205, dynamically indicated via the second control signaling 220, or predefined in a standard.
[0112] Based on switching to PUCCH set 210-b, UE 115 and network entity 105 can operate in PUCCH set 210-b (e.g., a non-default PUCCH group) for a duration of timer 235. The duration (T) of timer 235 can be pre-defined in standards, signaled via first control signaling 205, or dynamically indicated via second control signaling 220. UE 115 and network entity 105 can set (e.g., start) the duration of timer 235 after a duration of threshold time offset 230 (e.g., when the device starts operating in PUCCH set 210-b). That is, UE 115 and network entity 105 can start timer 235 in response to starting to use (e.g., transmit or monitor) PUCCH resource occasions 215 in PUCCH set 210-b.
[0113] In some examples, while UE 115 and network entity 105 are operating using PUCCH set 210-b (e.g., a non-default PUCCH group), UE 115 and network entity 105 can reset the duration of the timer in response to transmission of uplink message 225-b. In an example, UE 115 can transmit uplink message 225-b via PUCCH resource occasions 215 in PUCCH set 210-b. In response to transmitting uplink message 225-b, UE 115 and network entity 105 can reset timer 235 and continue to operate using PUCCH resource occasions 215 in PUCCH set 210-b until timer 235 expires. After timer 235 expires, UE 115 and network entity 105 can switch from operating using PUCCH set 210-b to operating using PUCCH set 210-a (e.g., a default PUCCH group).
[0114] In some examples, the UE 115 and the network entity 105 can switch from operating in the PUCCH set 210-b to operating in the PUCCH set 210-a in response to the third control signaling 240. For example, the UE 115 or the network entity 105 can transmit the third control signaling 240 indicating to switch the UE 115 from operating using the PUCCH set 210-b (e.g., a non-default PUCCH group) to operating using the PUCCH set 210-a when operating using the PUCCH set 210-b. In such examples, the UE 115 can transmit the third control signaling 240-a, which can be an example of UCI. Alternatively, the network entity 105 can transmit the third control signaling 240-b, which can be an example of DCI. The third control signaling 240 can include the same indications and formats described herein with reference to the second control signaling 220. That is, the third control signaling 240 can include the codepoint values indicated in Table 1 or include the implicit indication as described herein.
[0115] Based on the expiration of the timer 235 or the third control signaling 240, the UE 115 and the network entity 105 can perform the switch from the PUCCH set 210-b to the PUCCH set 210-a according to the threshold time offset 230 (e.g., the application delay) from the third control signaling 240 or the expiration of the timer 235. That is, the UE 115 can transmit one or more uplink messages 225 via the PUCCH resource occasions 215 in the PUCCH set 210-b, and the network entity 105 can monitor the PUCCH resource occasions 215 in the PUCCH set 210-b while the timer 235 is active. Based on the expiration of the timer 235, the UE 115 and the network entity 105 can switch to operating in the PUCCH set 210-a (e.g., a default PUCCH group). Additionally or alternatively, the UE 115 or the network entity 105 can transmit the third control signaling 240 indicating to switch from the PUCCH set 210-b to the PUCCH set 210-a while operating using the PUCCH resource occasions 215 in the PUCCH set 210-b.
[0116] By enabling the network entity 105 to perform PUCCH adaptation (e.g., skip one or more PUCCH resource occasions 215 or switch between PUCCH sets 210), the network entity 105 can reduce power consumption associated with monitoring the PUCCH resource occasions 215. In this way, the network entity 105 can implement additional power saving techniques for NES.
[0117] FIG. 3An example of a state diagram 300 supporting a technique for PUCCH adaptation according to one or more aspects of this disclosure is shown. Aspects of state diagram 300 may be derived from, as referenced herein. FIG. 1 and FIG. 2 The wireless communication system 100 and wireless communication system 200 described herein are implemented in various aspects. For example, state diagram 300 may be implemented by network entity 105 and UE 115, which may be examples of the corresponding devices described herein. Network entity 105 and UE 115 may implement aspects of state diagram 300 in order to perform as described herein. FIG. 2 The described PUCCH set switching.
[0118] For example, network entity 105 can be configured with PUCCH set 305-a and PUCCH set 305-b, which can be referenced in this paper. FIG. 2 An example of the described PUCCH set 210. PUCCH set 305-a may be referred to as the default PUCCH group, while PUCCH set 305-b may be referred to as the non-default PUCCH group. Each PUCCH set 305 may have different levels of PUCCH monitoring activity for network entity 105. For example, PUCCH set 305-a may include fewer PUCCH resource opportunities relative to those in PUCCH set 305-b, or vice versa. In some examples, PUCCH set 305-b may be an empty set, which will be used by UE 115 to skip one or more PUCCH resource opportunities, as referenced herein. FIG. 4 Further described.
[0119] Network entity 105 may send a first control signaling (e.g., RRC signaling) to UE 115 instructing PUCCH set 305, wherein UE 115 and network entity 105 may operate using PUCCH resources in PUCCH set 305-a or at the time when they begin using those PUCCH resources. The first control signaling may be referenced herein. FIG. 2 An example of the first control signaling 205 described herein. Alternatively, UE 115 and network entity 105 may respond to a second control signaling (e.g., a UCI from UE 115 or a DCI from network entity 105) to operate using PUCCH resources in PUCCH set 305-a or to begin using those PUCCH resources, the second control signaling being as referenced herein. FIG. 2 An example of the second control signaling 220 described. UE 115 and network entity 105 may operate using PUCCH resources in PUCCH set 305-a at opportune times, while periodically indicating the use of PUCCH set 305-a via the second control signaling.
[0120] In some examples, the UE 115 and the network entity 105 can switch from using the PUCCH set 305-a to using the PUCCH set 305-b based on the second control signaling as described herein with reference to FIG. 2. Additionally, or alternatively, the UE 115 and the network entity 105 can switch from using the PUCCH set 305-a to using the PUCCH set 305-b in response to a PUCCH transmission (e.g., an uplink message 225) transmitted using the PUCCH set 305-a. FIG. 2
[0121] The UE 115 and the network entity 105 can operate using the PUCCH set 305-b according to a threshold time offset, which can be defined from the reception or transmission time of the second control signaling or the PUCCH transmission to the start of using the PUCCH set 305-b. In some examples, the UE 115 and the network entity 105 can operate using the PUCCH set 305-b for a duration of a timer, such as the timer 235 as described herein with reference to FIG. 2. The UE 115 and the network entity 105 can start the timer after the threshold time offset (e.g., when the device starts operating using the PUCCH set 305-b). FIG. 2
[0122] In some examples, the UE 115 and the network entity 105 can reset the timer based on the PUCCH transmission, continuing to operate using the PUCCH set 305-b. That is, in response to the PUCCH transmission, the UE 115 and the network entity 105 can reset the duration of the timer. Additionally, or alternatively, the UE 115 and the network entity 105 can continue to operate using the resource occasions in the PUCCH set 305-b based on third control signaling, such as the third control signaling as described herein with reference to FIG. 2. For example, the UE 115 can transmit the third control signaling (e.g., UCI), or the network entity 105 can transmit the third control signaling (e.g., DCI), indicating to continue to operate using the resource occasions in the PUCCH set 305-b or otherwise use the resource occasions. The UE 115 and the network entity 105 can switch from using the PUCCH set 305-b to using the PUCCH set 305-a in response to an expiration of the timer as described herein with reference to FIG. 2. FIG. 2 FIG. 2 FIG. 2 In some examples, the UE 115 and the network entity 105 can switch from using the PUCCH set 305-b to using the PUCCH set 305-a based on the third control signaling, such as the third control signaling 240 as described herein with reference to FIG. 2.
[0123] By enabling the network entity 105 and the UE 115 to perform PUCCH adaptation (e.g., switching between PUCCH sets 305 or skipping PUCCH resource occasions), the network entity 105 can reduce power consumption. Moreover, by switching between PUCCH sets 305 with different levels of PUCCH resource occasions, the network entity 105 and the UE 115 can switch between sparser and denser PUCCH sets 305 based on traffic of the UE, buffer size of the UE, or network capacity, thereby facilitating increased or improved coordination between devices.
[0124] FIG. 4 An example of a timing diagram 400 that supports techniques for PUCCH adaptation is shown, in accordance with one or more aspects of the present disclosure. Aspects of the timing diagram 400 can implement, or be implemented by, aspects of the wireless communications system 100, the wireless communications system 200, and the state diagram 300 as described herein. For example, the timing diagram 400 can be implemented by a UE 115 and a network entity 105, which can be examples of the network entity 105 and the UE 115 described herein. Moreover, the network entity 105 and the UE 115 can implement techniques of the timing diagram 400 in order to skip one or more PUCCH resource occasions 410. FIG. 1 to FIG. 3
[0125] In some implementations, the network entity 105 can configure multiple PUCCH sets 405 (e.g., such as PUCCH set 405-a and PUCCH set 405-b) to have different levels or numbers of PUCCH resource occasions 410. Such PUCCH sets 405 can be examples of the PUCCH sets 210 and the PUCCH sets 305 described herein with reference to FIG. 2 and FIG. 3 For example, PUCCH set 405-a can include one or more PUCCH resource occasions 410, while PUCCH set 405-b can not include PUCCH resource occasions 410. As such, PUCCH set 405-b can be referred to as an empty set.
[0126] The network entity 105 can transmit, to the UE 115, first control signaling (e.g., RRC signaling) indicating the PUCCH set 405-a and the PUCCH set 405-b. The first control signaling can be as described with reference to FIG. 2 An example of the first control signaling 205 is described. In some examples, the network entity 105 can determine one or more PUCCH transmissions to skip based on a PUCCH format of the PUCCH transmission, based on a PUCCH resource occasion 410, or based on a PUCCH set 405 that the UE 115 and the network entity 105 are using. That is, in the first control signaling, the network entity 105 can indicate to the UE 115 one or more PUCCH formats (e.g., PUCCH formats 0-4) that the UE 115 can skip. In one example, the network entity 105 can indicate to the UE 115 that the UE 115 can skip PUCCH transmissions with PUCCH formats 0 and 1, but not PUCCH transmissions with PUCCH formats 2, 3, or 4. Further, the network entity 105 can indicate to the UE 115 that the UE 115 will refrain from skipping one or more PUCCH resource occasions 410 associated with a PUCCH set 405 (e.g., such as a default PUCCH set or a particular PUCCH set).
[0127] In response to receiving the first control signaling, the UE 115 and the network entity 105 can employ or otherwise begin using the PUCCH resource occasions 410 in the PUCCH set 405-a. In some examples, the UE 115 or the network entity 105 can dynamically communicate second control signaling 415 (e.g., UCI from the UE 115 or DCI from the network entity 105) that indicates for the UE 115 to skip one or more PUCCH resource occasions 410 (e.g., skip one or more PUCCH transmissions) for a duration of a timer 425. The second control signaling 415 can be as described with reference to FIG. 2 An example of the second control signaling 220 is described. In such examples, the timer 425 can be a predetermined value indicated in a standard (e.g., such as a 3GPP standard). Additionally or alternatively, the UE 115 or the network entity 105 can select a duration of the timer from a predefined set of durations of the timer (e.g., predefined in a standard) and indicate the selected duration of the timer 425 via the second control signaling 415.
[0128] In response to the second control signaling 415 (e.g., dynamic signaling), the network entity 105 can immediately stop detecting associated PUCCH resource occasions in the PUCCH set 405-a starting from the first PUCCH resource occasion 410 after the second control signaling 415. Likewise, the UE 115 can immediately stop transmitting PUCCH transmissions via PUCCH resource occasions 410 in the PUCCH set 405-a starting from the first PUCCH resource occasion 410 after the second control signaling 415. That is, in response to the second control signaling 415, the UE 115 and the network entity 105 can immediately switch from using PUCCH resource occasions in the PUCCH set 405-a to operating in the PUCCH set 405-b (e.g., an empty set).
[0129] Alternatively, the network entity 105 and the UE 115 can switch from the PUCCH set 405-a to the PUCCH set 405-b (e.g., an empty set) according to a threshold time offset 420 (e.g., an application delay) between the second control signaling 415 and the first PUCCH resource occasion 410, where the network entity 105 stops detecting and the UE 115 stops transmitting associated PUCCH transmissions. That is, the network entity 105 can continue to monitor PUCCH resource occasions 410 in the PUCCH set 405-a during the threshold time offset 420 and stop monitoring PUCCH resource occasions 410 after the threshold time offset 420 (e.g., switch to the PUCCH set 405-b). The threshold time offset 420 can be as described with reference to the examples of threshold time offsets 230. FIG. 2
[0130] The UE 115 and the network entity 105 can skip PUCCH transmissions (e.g., operate in the PUCCH set 405-a) for a duration of a timer 425. Based on expiration of the duration of the timer 425, the UE 115 and the network entity 105 can immediately or after the threshold time offset 420 switch to operating in the PUCCH set 405-a. In this way, when the UE 115 stops transmitting PUCCH transmissions via PUCCH resource occasions in the PUCCH set 405-a, the network entity 105 can have an opportunity to enter a sleep mode, thereby reducing power consumption at the network entity 105 and conserving energy at the network entity.
[0131] FIG. 5 An example of a process flow 500 that supports techniques for PUCCH adaptation is shown in accordance with one or more aspects of the present disclosure. Aspects of the process flow 500 can implement or be implemented by aspects of the wireless communication system 100, the wireless communication system 200, the state diagram 300, and the timing diagram 400 as described herein. For example, aspects of the process flow 500 can be implemented by a UE 115 and a network entity 105, which can be examples of the corresponding devices described herein. The UE 115 and the network entity 105 can implement techniques of the process flow 500 to enable switching between PUCCH sets, resulting in power savings at the network entity 105. FIG. 1 to FIG. 4 Aspects of the process flow 500 can enable switching between PUCCH sets, resulting in power savings at the network entity 105. For example, the network entity 105 can transmit a first control signaling indicating a first set of PUCCH resource occasions (e.g., such as the PUCCH set 210-a, the PUCCH set 305-a, or the PUCCH set 405-a) and a second set of PUCCH resource occasions (e.g., such as the PUCCH set 210-b, the PUCCH set 305-b, and the PUCCH set 405-b). The UE 115 can transmit an uplink message via a first PUCCH resource occasion (e.g., such as the PUCCH resource occasion 215 or the PUCCH resource occasion 410). In response to the first control signaling, the UE 115 and the network entity 105 can employ the first set of PUCCH resource occasions or otherwise begin operating using the first set of PUCCH resource occasions. The UE 115, the network entity 105, or both can dynamically indicate second control signaling indicating a switch from using resource occasions in the first set of PUCCH resource occasions to using the second set of PUCCH resource occasions. In some examples, the UE 115 can transmit UCI indicating the switch, where the UCI is second control signaling as described herein with reference to FIGs. 1-4. Alternatively, the network entity 105 can transmit DCI indicating the switch, where the DCI is second control signaling as described herein with reference to FIGs. 1-4.
[0132] In the following description of the process flow 500, operations can be performed in a different order than shown. Certain operations can also be left out of the process flow 500, or other operations can be added to the process flow 500. Moreover, although some operations or signaling are shown as occurring at different times for discussion purposes, these operations can actually occur at the same time.
[0133] At 505, the network entity 105 can transmit first control signaling (e.g., such as the first control signaling 205) indicating at least a first set of PUCCH resource occasions (e.g., such as the PUCCH set 210-a, the PUCCH set 305-a, or the PUCCH set 405-a) and a second set of PUCCH resource occasions (e.g., such as the PUCCH set 210-b, the PUCCH set 305-b, and the PUCCH set 405-b). At 510, the UE 115 can transmit an uplink message via a first PUCCH resource occasion (e.g., such as the PUCCH resource occasion 215 or the PUCCH resource occasion 410). That is, in response to the first control signaling, the UE 115 and the network entity 105 can employ the first set of PUCCH resource occasions or otherwise begin operating using the first set of PUCCH resource occasions.
[0134] At 515, the UE 115, the network entity 105, or both can dynamically indicate second control signaling indicating a switch from using resource occasions in the first set of PUCCH resource occasions to using the second set of PUCCH resource occasions. In some examples, the UE 115 can transmit UCI indicating the switch, where the UCI is second control signaling as described herein with reference to FIGs. 1-4. Alternatively, the network entity 105 can transmit DCI indicating the switch, where the DCI is second control signaling as described herein with reference to FIGs. 1-4. FIG. 2 FIG. 2
[0135] At 520-a and 520-b, the UE 115 and the network entity 105 can switch from using resource occasions in the first set of PUCCH resource occasions to using resource occasions in the second set of PUCCH resource occasions. In some examples, the switch can be based on the second control signaling. In some other examples, the switch can be in response to the transmission of the uplink message at 510.
[0136] In some examples, the second set of PUCCH resource occasions can be an empty set, as described herein with reference to FIGs. 5A and 5B. In such examples, the UE 115 and the network entity 105 can skip one or more uplink messages for a duration of the timer. In such examples, the UE 115 and the network entity 105 can skip such uplink messages based on a PUCCH format of the one or more uplink messages.
