The disclosures of these prior applications are considered a part of and incorporated by reference into this patent application. Background Art

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for discontinuous reception.

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more network nodes that support communication for wireless communication devices, such as user equipment (UE) or multiple UEs. The UE may communicate with the network node via downlink and uplink communications. A "downlink" (or "DL") refers to the communication link from the network node to the UE, and an "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, regional, and / or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by: improving spectrum efficiency; reducing costs; improving services; utilizing new spectrum; and better integrating with other open standards by using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink and CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink; as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0052] User equipment (UE) may operate using discontinuous reception (DRX) to save power. The UE may perform DRX according to a DRX cycle that repeats with a configured periodicity. The DRX cycle may include a DRX on duration (e.g., during which the UE is awake or active) and a DRX off duration (e.g., during which the UE has the opportunity to enter a sleep state). During the DRX on duration, the UE may be active to monitor a downlink control channel (e.g., a physical downlink control channel (PDCCH)) to obtain downlink control information (DCI) related to the UE. If the UE does not detect DCI, the UE may enter a sleep state (e.g., by not transmitting and / or receiving, and / or by deactivating one or more components of the UE) at the end of the DRX on duration and the beginning of the DRX off duration. If the UE detects DCI, the UE may remain active to send and / or receive communications for the duration of a timer (which may be referred to as an "inactivity timer"). Thus, the UE may remain active for a portion of the DRX off duration until the timer expires, at which point the UE may enter a sleep state for the remainder of the DRX off duration.

[0053] "DRX active time" or "DRX active duration" may refer to a time interval of a DRX cycle that corresponds to the DRX on duration (e.g., if the UE does not decode any PDCCH communication intended for the UE during the DRX on duration), or corresponds to the DRX on duration and a portion of the DRX off duration during which a timer is running (e.g., if the UE does decode a PDCCH communication intended for the UE during the DRX on duration). "DRX inactive time" or "DRX inactive duration" may refer to a time interval of a DRX cycle that corresponds to the DRX off duration (e.g., if the UE does not decode any PDCCH communication intended for the UE during the previous DRX on duration), or corresponds to a portion of the DRX off duration after the timer expires (e.g., if the UE does decode a PDCCH communication intended for the UE during the previous DRX on duration). In some examples, the UE may send and / or receive communications during the DRX inactive time. For example, the UE may receive communications configured to occur periodically, such as a periodic reference signal. The UE's transmission and / or reception outside the DRX active time can reduce the chance of the network node entering the sleep state.

[0054] Therefore, the network node may provide an indication (which may be referred to as a "skip indication") to the UE, which indicates that the UE will skip (e.g., discard) the transmission and / or reception of specific communications that might otherwise be communicated during the DRX inactive time. For example, the skip indication (e.g., information in the DCI, in a medium access control (MAC) control element, or in radio resource control (RRC) signaling) may indicate that the UE will skip one or more types of communications (e.g., semi-persistent scheduling (SPS) communications and / or configured grant communications, etc.) that are transmitted and / or received during the DRX inactive time. The skip indication may enable the network node to reduce transmission and / or reception during the DRX inactive time, thereby improving power saving of the network node. However, such a reduction in transmission and / or reception may affect the overall performance in the wireless network. For example, the UE may measure a reference signal sent by the network node to establish (or reestablish) and maintain a reliable communication link with the network. In some cases, the reference signal may be sent periodically during the DRX inactive time. Therefore, if the UE skips reception of the reference signal during the DRX inactive time according to the skip indication, the UE's reception of the reference signal may be delayed until the DRX active time, thereby affecting the overall communication delay.

[0055] Some techniques and apparatus described herein enable a UE to receive and measure reference signals during DRX inactivity time. In some aspects, a UE may send an indication (which may be referred to as a "measurement indication") that the UE performs measurements of reference signals during DRX inactivity time (e.g., that the UE has the capability to perform measurements of reference signals). For example, the measurement indication may indicate the UE's capability to perform measurements and may be provided in a UE capability information message (e.g., sent via RRC signaling). The measurement indication may provide an exception to a skip indication sent by a network node. In response to the measurement indication, the network node may send a reference signal to the UE during DRX inactivity time, and the UE may receive and measure the reference signal during the DRX inactivity time. In this way, the amount of delay for the UE to receive and measure the reference signal may be reduced, thereby improving communication latency and overall performance of UE communications.

[0056] In some examples, multiple UEs in a cell may perform DRX according to the same DRX cycle. However, the DRX activity times of the UEs may be different (e.g., may not completely overlap in time), which may be due to the UEs being configured with different DRX inactivity timer durations and / or due to the UEs starting the DRX inactivity timers at different times. Therefore, if the network node has provided a skip indication to one or more UEs, the maximum time duration for which the network node may discard transmission and / or reception according to the skip indication may correspond to the time overlap of the DRX inactivity times of all UEs across the cell. The UE may lack information about the DRX inactivity times of other UEs. Therefore, even if the network node is active and communicating with other UEs that have not yet entered a sleep state, the UE may follow the skip indication during the UE's inactivity time. Therefore, communication at the UE may be delayed, thereby affecting the overall communication latency.

[0057] Some techniques and apparatuses described herein implement an indication of a time duration corresponding to a temporal overlap of DRX inactivity times for all UEs across a cell. For example, a UE may receive information identifying the time duration from a network node (e.g., configuration information such as in an RRC configuration). During the time duration, the UE may apply a skip indication, and outside of the time duration, the UE may communicate without applying the skip indication. In this manner, the amount of delay in the UE's communications may be reduced, thereby improving data communication latency and overall performance of the UE's communications.

[0058] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It will be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods that are practiced using other structures, functionality, or structure and functionality in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0059] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0060] Although various aspects may be described herein using terminology generally associated with 5G or New Radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT, and / or post-5G (e.g., 6G) RATs.

[0061] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (illustrated as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (illustrated as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, meaning that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated base station), meaning that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0062] In some examples, network node 110 is or includes a network node (such as an RU) that communicates with UE 120 via a radio access link. In some examples, network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or communicates with a core network via a backhaul link. In some examples, network node 110 (such as a converged network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. Network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, an RU, a CU, a mobility element of a network, a core network node, a network element, network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 using any suitable transport network via various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks.

[0063] In some examples, network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​network node 110 and / or a network node subsystem serving that coverage area, depending on the context in which the term is used. Network node 110 may provide communication coverage for a macrocell, a picocell, a femtocell, and / or another type of cell. A macrocell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs 120 with service subscriptions. A picocell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscriptions. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 associated with the femtocell (e.g., UEs 120 in a closed subscriber group (CSG)). A network node 110 for a macrocell may be referred to as a macro network node. A network node 110 for a picocell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1In the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0064] In some aspects, the term "base station" or "network node" may refer to a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near-RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions, such as those described herein in conjunction with network node 110. In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of multiple different devices (which may be located in the same geographic location or different geographic locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions but not another base station function. In this way, a single device may include more than one base station.

[0065] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. Figure 1 In the example shown in , a network node 110 d (e.g., a relay network node) may communicate with a network node 110 a (e.g., a macro network node) and a UE 120 d to facilitate communications between the network node 110 a and the UE 120 d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0066] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0067] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.

[0068] UEs 120 may be dispersed throughout wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. UE 120 may be a cellular phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device configured to communicate via a wireless or wired medium.

[0069] Some UEs 120 may be considered machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that can communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. The UE 120 may be included within a housing that houses components of the UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0070] Generally speaking, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, air interface, etc. A frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0071] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0072] The electromagnetic spectrum is typically subdivided by frequency / wavelength into various categories, bands, channels, etc. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz - 7.125 GHz) and FR2 (24.25 GHz - 52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0073] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125 GHz to 24.25 GHz). The frequency bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation to more than 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0074] With the above examples in mind, unless otherwise specifically stated, it should be understood that if the term "sub-6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. Additionally, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a, FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0075] In some aspects, UE 120 may include a communications manager 140. As described in greater detail elsewhere herein, communications manager 140 may send an indication that UE 120 is to perform measurements of one or more reference signals during one or more DRX inactivity times of one or more DRX cycles; and, in response to the indication, receive the one or more reference signals during the DRX inactivity times of one or more DRX cycles of the one or more DRX cycles. As described in greater detail elsewhere herein, communications manager 140 may receive information identifying a time duration of the DRX inactivity times of the DRX cycles for applying an indication to skip at least one of transmission or reception during the DRX inactivity times; and communicate during the time duration in accordance with the indication. Additionally or alternatively, communications manager 140 may perform one or more other operations described herein.

[0076] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may receive an indication that the UE is performing measurements of one or more reference signals during one or more DRX inactivity times of one or more DRX cycles; and, in response to the indication, transmit the one or more reference signals during the DRX inactivity times of one or more DRX cycles of the one or more DRX cycles. As described in more detail elsewhere herein, the communication manager 150 may transmit information identifying a time duration of the DRX inactivity times of the DRX cycles for applying the indication to skip at least one of transmission or reception during the DRX inactivity times; and, in accordance with the indication, communicate during the time duration. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0077] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0078] Figure 22 is a diagram illustrating example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a through 234t, such as T antennas (T ≥ 1). The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R ≥ 1). The network node 110 of example 200 includes one or more radio frequency components, such as antennas 234 and a modem 232. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include radio frequency components, such as one or more CUs or one or more DUs, that facilitate direct communication with the UE 120.

[0079] At network node 110, transmit processor 220 may receive data intended for UE 120 (or a group of UEs 120) from data source 212. Transmit processor 220 may select one or more modulation and coding schemes (MCS) for UE 120 based at least in part on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 may process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120 and may provide data symbols for UE 120. Transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. Transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input, multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, as applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a through 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or frequency upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a through 232t may transmit the set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a through 234t).

[0080] At the UE 120, a set of antennas 252 (shown as antennas 252a through 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a through 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use the demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols, if applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to a data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine, among other things, a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter. In some examples, one or more components of the UE 120 may be included in a housing 284.

[0081] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0082] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. The antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0083] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from the controller / processor 280. The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, if applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform aspects of any of the methods described herein.

[0084] At network node 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., a demodulator component (shown as DEMOD) of modem 232), detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include a communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, modem 232 of network node 110 may include a modulator and a demodulator. In some examples, network node 110 includes a transceiver. The transceiver may include any combination of an antenna 234, a modem 232, a MIMO detector 236, a receive processor 238, a transmit processor 220, and / or a TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein.

[0085] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the may perform one or more techniques associated with communication skipping in DRX, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the may perform or direct e.g. Figure 12 The process of 1200 Figure 13 The process of 1300 Figure 14 The process of 1400 Figure 15 1500 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly or after compilation, conversion, and / or interpretation) by one or more processors of network node 110 and / or UE 120, may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 12 The process of 1200 Figure 13 The process of 1300 Figure 14 The process of 1400 Figure 15 The operations of process 1500 and / or other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among others.

[0086] In some aspects, the UE 120 includes means for transmitting an indication that the UE 120 is to perform measurements of one or more reference signals during one or more DRX inactivity times of one or more DRX cycles; and / or means for receiving one or more reference signals during a DRX inactivity time of one or more DRX cycles in response to the indication. In some aspects, the UE 120 includes means for receiving information identifying a time duration of the DRX inactivity time of the DRX cycle, the time duration being used to apply an indication to skip at least one of transmission or reception during the DRX inactivity time; and / or means for communicating during the time duration in accordance with the indication. Means for the UE 120 to perform the operations described herein may include, for example, one or more of the communications manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0087] In some aspects, the network node 110 includes: means for receiving an indication that a UE performs measurements of one or more reference signals during one or more DRX inactivity times of one or more DRX cycles; and / or means for transmitting one or more reference signals during the DRX inactivity times of one or more DRX cycles in response to the indication. In some aspects, the network node 110 includes means for transmitting information identifying a time duration of the DRX inactivity times of the DRX cycles, the time duration being used to apply the indication to skip at least one of transmission or reception during the DRX inactivity times; and / or means for communicating during the time duration in accordance with the indication. Means for the network node 110 to perform the operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0088] Although Figure 2 The blocks in FIG. 2 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component, or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0089] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0090] The deployment of a communication system such as a 5G NR system can be arranged in a variety of ways with various components or constituent parts. In a 5G NR system or network, a network node, a network entity, a mobility element of the network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR base station, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) performing base station functionality can be implemented as an aggregated base station (also known as an independent base station or a monolithic base station) or a decomposed base station. A "network entity" or a "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0091] A converged base station (e.g., a converged network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, the CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually spread across one or more other network nodes. The DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), among others.

[0092] Base station type operation or network design may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate scaling of the communication system by separating base station functionality into one or more units that can be deployed separately. A disaggregated base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of the disaggregated base station may be configured for wired or wireless communication with at least one other unit of the disaggregated base station.

[0093] In some aspects, the term "receive" and its variations (e.g., "received" and / or "received", etc.) may alternatively be referred to as "obtain" or its respective variations (e.g., "obtained" and / or "obtained", etc.). Similarly, the term "send" and its variations (e.g., "send" and / or "sent", etc.) may alternatively be referred to as "provide" or its corresponding variations (e.g., "provide" and / or "provided", etc.), "generate" or its corresponding variations (e.g., "generate" and / or "generated", etc.), and / or "output" or its corresponding variations (e.g., "output" and / or "outputted", etc.).

[0094] Figure 3FIG2 is a diagram illustrating an example decomposed base station architecture 300 according to the present disclosure. The decomposed base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more decomposed control units (such as a near-RT RIC 325 via an E2 link, a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via respective midhaul links (such as via an F1 interface). Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0095] Each of the units (including the CU 310, DU 330, RU 340) and the near-RT RIC 325, the non-RT RIC 315, and the SMO framework 305 may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit, may be configured to communicate with one or more of the other units via the transmission medium. In some examples, each of the units may include a wired interface configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium, and a wireless interface that may include a receiver, a transmitter, or a transceiver (such as an RF transceiver) configured to receive signals or transmit signals to one or more of the other units via a wireless transmission medium, or both.

[0096] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, among others. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.

[0097] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, a DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more higher physical (PHY) layers, at least in part according to a functional split (such as that defined by 3GPP). In some aspects, the one or more higher PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, a DU 330 may also host one or more lower PHY layers, such as those implemented by one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0098] Each RU 340 may implement low-layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions based on functional split (e.g., functional split defined by 3GPP) (such as low-layer functional split), such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0099] The SMO framework 305 can be configured to support RAN deployment and provisioning of both non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via an operations and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform (such as the Open Cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as the O2 interface). Such virtualized network elements can include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some implementations, the SMO framework 305 can communicate with hardware aspects of the 4G RAN (such as the Open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0100] The non-RT RIC 315 can be configured to include logic that enables non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 can be coupled to or in communication with the near-RT RIC 325 (e.g., via an A1 interface). The near-RT RIC 325 can be configured to include logic that enables near-real-time control and optimization of RAN elements and resources through data collection and actions over an interface (e.g., via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0101] In some implementations, the non-RT RIC 315 can receive parameters or external enrichment information from an external server to generate an AI / ML model to be deployed in the near-RT RIC 325. Such information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or from network functions at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 can be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 can monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or through the creation of RAN management policies (such as A1 interface policies).

[0102] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0103] Figure 4 4 are diagrams illustrating examples 400, 410, and 420 of a beam management process according to the present disclosure. Figure 4 As shown, examples 400, 410, and 420 include UE 120 communicating with network node 110 in a wireless network (e.g., wireless network 100). Figure 4 The devices shown in the figure are provided as examples, and the wireless network may support communication and beam management between other devices (e.g., between UE 120 and network node 110 or TRP, between mobile terminating nodes and control nodes, between integrated access and backhaul (IAB) child nodes and IAB parent nodes, and between scheduled nodes and scheduling nodes). In some examples, UE 120 and network node 110 may be in a connected state (e.g., an RRC connected state).

[0104] like Figure 4 As shown, example 400 may include a network node 110 (e.g., one or more network node devices such as RU, DU, and / or CU, etc.) communicating with a UE 120 to perform beam management. Example 400 depicts a first beam management process (e.g., P1 beam management). The first beam management process may be referred to as a beam selection process, an initial beam acquisition process, a beam scanning process, a cell search process, and / or a beam search process. Figure 4 As shown in example 400, a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS) may be sent from network node 110 to UE 120. The CSI-RS may be configured to be periodic (e.g., using RRC signaling), semi-persistent (e.g., using medium access control (MAC) control element (MAC-CE) signaling), and / or aperiodic (e.g., using downlink control information (DCI)).

[0105] The first beam management process may include network node 110 performing beam scanning on multiple transmit (Tx) beams. Network node 110 may use each transmit beam used for beam management to transmit an SSB and / or CSI-RS. To enable UE 120 to perform receive (Rx) beam scanning, the network node may transmit each SSB and / or CSI-RS multiple times (e.g., repeatedly) within the same reference signal resource set using a transmit beam, so that UE 120 can scan through the receive beam in multiple transmission instances. For example, in a scenario where network node 110 has a set of N transmit beams and UE 120 has a set of M receive beams, SSB and / or CSI-RS may be transmitted M times on each of the N transmit beams, so that UE 120 can receive M instances of SSB and / or CSI-RS per transmit beam. In other words, for each transmit beam of network node 110, UE 120 may perform beam scanning on its receive beam. Thus, the first beam management procedure may enable UE 120 to measure (Layer 1 (L1) RSRP measurement) SSB and / or CSI-RS on different transmit beams using different receive beams to support selection of a network node 110 transmit beam / UE 120 receive beam pair. UE 120 may report the measurements to network node 110 to enable network node 110 to select one or more beam pairs for communication between network node 110 and UE 120.

[0106] like Figure 4As shown, example 410 may include network node 110 communicating with UE 120 to perform beam management. Example 410 depicts a second beam management procedure (e.g., P2 beam management). The second beam management procedure may be referred to as a beam refinement procedure, a network node beam refinement procedure, a TRP beam refinement procedure, and / or a transmit beam refinement procedure. Figure 4 As shown in example 410, a CSI-RS may be configured to be transmitted from network node 110 to UE 120. The CSI-RS may be configured to be aperiodic (e.g., using DCI). The second beam management procedure may include network node 110 performing beam scanning on one or more transmit beams (e.g., a smaller set of transmit beams compared to the first beam management procedure). The one or more transmit beams may be a subset of all transmit beams associated with network node 110 (e.g., determined based at least in part on measurements reported by UE 120 in conjunction with the first beam management procedure). Network node 110 may transmit a CSI-RS using each of the one or more transmit beams used for beam management. UE 120 may measure each CSI-RS using a single (e.g., identical) receive beam (e.g., determined based at least in part on measurements performed in conjunction with the first beam management procedure). For example, UE 120 may measure each CSI-RS without scanning the receive beams. This second beam management procedure may enable network node 110 to select the best transmit beam based at least in part on CSI-RS measurements reported by UE 120 (e.g., measured by UE 120 using a single receive beam). For example, UE 120 may report the index (e.g., CSI-RS Resource Indicator (CRI)) and signal strength (e.g., L1 RSRP) of the strongest beam.

[0107] like Figure 4 As shown, example 420 depicts a third beam management process (e.g., P3 beam management). The third beam management process may be referred to as a beam refinement process, a UE beam refinement process, and / or a receive beam refinement process. Figure 4As shown in example 420, one or more CSI-RSs may be configured to be transmitted from network node 110 to UE 120. The CSI-RSs may be configured to be aperiodic (e.g., using DCI). The third beam management procedure may include network node 110 transmitting the one or more CSI-RSs using a single transmit beam (e.g., determined based at least in part on measurements reported by UE 120 in conjunction with the first beam management procedure and / or the second beam management procedure). To enable UE 120 to perform receive beam scanning, the network node may transmit (e.g., repeatedly) the CSI-RS multiple times (consecutively) within the same reference signal resource set using the transmit beam, such that UE 120 may scan through the one or more receive beams in multiple transmission instances. The one or more receive beams may be a subset of all receive beams associated with UE 120 (e.g., determined based at least in part on measurements performed in conjunction with the first beam management procedure and / or the second beam management procedure). The third beam management procedure may enable network node 110 and / or UE 120 to select the best receive beam based at least in part on reported measurements received from UE 120 (e.g., reported measurements of the CSI-RS of the transmit beam using the one or more receive beams). In some examples, UE 120 may select the best receive beam without reporting the measurement results to network node 110. Although the first, second, and third beam management procedures are described herein with reference to SSBs and / or CSI-RSs, another type of reference signal, such as a positioning reference signal, may be used. In addition, the beam management procedures described herein as being performed using SSBs may be performed using CSI-RSs or another reference signal, and the beam management procedures described herein as being performed using CSI-RSs may be performed using SSBs or another reference signal.

[0108] In some examples, the receive beam scanning component of the first beam management process can be performed by UE 120 as a background process. However, due to analog beamforming limitations, receive beam scanning can disrupt reception of physical downlink shared channel (PDSCH) communications. Therefore, it may be beneficial for network node 110 to configure a designated signal in the form of a CSI-RS repeated with the same beamforming in order to initiate the third beam management process and support receive beam scanning by UE 120.

[0109] For beam reporting related to the beam management process, UE 120 may use CRI and / or SSB / Physical Broadcast Channel (PBCH) Block Resource Index (SSBRI) to report the index of one or more best beams. As described herein, UE 120 may report the signal strength measurement of the reported beam in the form of L1 RSRP. In some cases, UE 120 may report multiple beams. Here, UE 120 may report the absolute RSRP of the strongest beam (e.g., the beam with the highest L1 RSRP), and UE 120 may report the differential RSRP of one or more other beams.

[0110] In some examples, the network node 110 may indicate the CSI-RS resource configuration to the UE 120 (e.g., using an NZP-CSI-RS-ResourceSet information element, which indicates a set of non-zero power (NZP) CSI-RS resources (their identifiers) and set-specific parameters). When CSI-RS is used for beam management, and when repetition is disabled by the CSI-RS resource configuration (e.g., the repetition parameter in the NZP-CSI-RS-ResourceSet information element is set to "off"), a set of CSI-RS resources may be configured, each CSI-RS resource having a single port or two ports. For example, within a set of CSI-RS resources, all resources have the same number of ports. Each resource may correspond to a respective transmit beam direction from the network node 110. Additionally, the UE 120 may be configured to measure L1-RSRP for beam management (e.g., the reportQuantity parameter may be set to "cri-RSRP"). The L1-RSRP measurement may include: the CSI-RS power on the CSI-RS port, if a single port is used; or the average power across two ports, if two ports are used. The UE 120 may be expected to report the CRI of the strongest CSI-RS resource within the configured resource set (although selecting the strongest CSI-RS resource for reporting is not a requirement; the UE 120 may also be allowed to use other selection criteria), and the corresponding power (e.g., L1-RSRP) sorted in descending order.

[0111] When CSI-RS is used for beam management, and when repetition is enabled via CSI-RS resource configuration (e.g., the repetition parameter in the NZP-CSI-RS-ResourceSet information element is set to "on"), the CSI-RS may be intended for receive beam scanning. Here, multiple configured resources may be associated with the same transmit beam direction. In addition, the UE 120 may change the simulated beamforming direction in the UE 120's receiver and compare the signal strengths in different directions. The receive direction with the strongest received signal may then be used to receive other signals from the corresponding transmit beam direction. In some cases, these operations are transparent because the UE 120 may not be expected to report measurement results to the network node 110.

[0112] When repetition is enabled, no actual repetition parameters may be configured for UE 120. Instead, in this context, "repetition" means that the resources within a resource set have the same repeated transmit beam direction so that the receive beam scanning operation of UE 120 makes sense.

[0113] In some examples, UE 120 may perform reference signal measurements in conjunction with time and frequency tracking, beam failure detection (BFD), and / or radio link monitoring (RLM). In time and frequency tracking, UE 120 may monitor one or more reference signals to maintain time and frequency synchronization of a set of reference signals. In BFD, network node 110 may send one or more BFD reference signals (e.g., SSB and / or CSI-RS) to UE 120. UE 120 may attempt to detect and measure the BFD reference signals. Based at least in part on UE 120 failing to detect a threshold amount of BFD reference signals or measurements of a threshold amount of BFD reference signals satisfying a measurement threshold, UE 120 may determine that a beam failure has occurred. In RLM, network node 110 may send one or more RLM reference signals (e.g., SSB and / or CSI-RS) to UE 120. UE 120 may perform measurements of the RLM reference signals to determine whether a radio link between UE 120 and network node 110 has failed. When UE 120 determines that the radio link has failed (eg, if the estimated link quality of all RLM reference signals fails to meet a threshold), UE 120 may provide an indication to network node 110 .

[0114] As indicated above, Figure 4 is provided as an example of a beam management process. Other examples of beam management processes may be used in conjunction with Figure 4For example, the UE 120 and the network node 110 may perform the third beam management procedure before performing the second beam management procedure, and / or the UE 120 and the network node 110 may perform a similar beam management procedure to select a UE transmit beam.

[0115] Figure 5 5 is a diagram illustrating an example 500 of a DRX configuration according to the present disclosure. Figure 5 As shown, example 500 includes UE 120 communicating with network node 110. In some examples, UE 120 may be in a connected state (e.g., an RRC connected state) with network node 110. For example, the DRX configuration may be for connected mode DRX (C-DRX).

[0116] like Figure 5 As shown, the network node 110 may send a DRX configuration to the UE 120 to configure a DRX cycle 505 for the UE 120. The DRX cycle 505 may include a DRX on duration 510 (e.g., during which the UE 120 is awake or active) and a DRX off duration 515 (e.g., during which the UE 120 has an opportunity to enter a DRX sleep state).

[0117] During the DRX-on duration 510, the UE 120 may be in an active state to monitor a downlink control channel (e.g., a physical downlink control channel (PDCCH)), as indicated by reference numeral 520. For example, the UE 120 may monitor the PDCCH for DCI related to the UE 120. If the UE 120 does not detect any PDCCH communications intended for the UE 120 during the DRX-on duration 510 and / or does not successfully decode any such PDCCH communications, the UE 120 may enter a sleep state at the end of the DRX-on duration 510 during the DRX-off duration 515, as indicated by reference numeral 525. In the sleep state, the UE 120 may avoid transmitting or receiving on the access link, may deactivate specific subcarriers or component carriers of the access link, and / or may deactivate one or more components of the UE 120. In this manner, the UE 120 may conserve battery power and reduce power consumption. As shown, the DRX cycle 505 may repeat at a configured periodicity according to the DRX configuration.

[0118] In the event that the UE 120 detects and / or successfully decodes a PDCCH communication intended for the UE 120, the UE 120 may remain in an active state (e.g., awake) for the duration of the DRX inactivity timer 530 (e.g., which may extend the active time). The UE 120 may start the DRX inactivity timer 530 at the time the PDCCH communication is received (e.g., in a transmit time interval (TTI), such as a timeslot or subframe, in which the PDCCH communication is received). The UE 120 may remain in an active state until the DRX inactivity timer 530 expires, at which point the UE 120 may enter a sleep state (e.g., for the remainder of the DRX off duration 515), as indicated by reference numeral 535. During the duration of the DRX inactivity timer 530, the UE 120 may continue to monitor PDCCH communications, may obtain downlink data communications scheduled by the PDCCH communications (e.g., on a downlink data channel such as the PDSCH), and / or may prepare and / or transmit uplink communications scheduled by the PDCCH communications (e.g., on a physical uplink shared channel (PUSCH)). The UE 120 may restart the DRX inactivity timer 530 each time a PDCCH communication of the UE 120 is detected for an initial transmission (e.g., but not for a retransmission). By operating in this manner, the UE 120 may conserve battery power and reduce power consumption by entering a sleep state.

[0119] As described herein, the DRX active time for UE 120 may be the time that UE 120 is active, which may correspond to the DRX on duration 510 (e.g., if UE 120 does not decode any PDCCH communications intended for UE 120), or may correspond to the DRX on duration 510 and a portion of the DRX off duration 515 during which the DRX inactivity timer 530 is running (e.g., if UE 120 does decode PDCCH communications intended for UE 120). The DRX inactivity time for UE 120 may be the remaining portion of the DRX cycle 505 after the DRX active time. For example, the DRX inactivity time for UE 120 may be the time that UE 120 is in a sleep state (e.g., an inactive state), which may correspond to the DRX off duration 515 (e.g., if UE 120 does not decode any PDCCH communications intended for UE 120), or may correspond to a portion of the DRX off duration 515 after expiration of the DRX inactivity timer 530 (e.g., if UE 120 does decode PDCCH communications intended for UE 120).

[0120] In some examples, UE 120 may send or receive communications outside of the active time of UE 120. For example, outside of the active time, UE 120 may receive system information, radio resource management (RRM) reference signals, beam management reference signals, BFD reference signals, PDSCH communications according to semi-persistent scheduling (SPS), and / or PDSCH communications scheduled by a dynamic grant of a PDCCH communication received in the active time (e.g., when a K0 value is greater than a DRX inactivity timer 530, where the K0 value represents a timing offset (e.g., in number of time slots) between a time slot containing a PDCCH communication with a scheduling DCI carrying a grant scheduling the PDSCH communication and a time slot containing a scheduled PDSCH communication (scheduled by the scheduling DCI)). For another example, outside of the active time, the UE 120 may transmit scheduling requests, communications according to configured grants, random access channel (RACH) communications (e.g., PRACH-ResourceDedicatedBFR for beam failure recovery (BFR)), PUSCH communications scheduled by dynamic grants of PDCCH communications received during the active time, and / or physical uplink control channel (PUCCH) communications carrying hybrid automatic repeat request acknowledgement feedback (HARQ-ACK) for PDSCH communications scheduled by PDCCH communications received during the active time. Transmission or reception by the UE 120 outside of the active time may limit the opportunity for the network node 110 to enter deep sleep (e.g., deeper sleep than micro-sleep with symbol-level granularity).

[0121] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0122] Figure 6 is a diagram illustrating an example 600 of a sidelink DRX configuration according to the present disclosure. In some cases, as described above with reference to Figure 5 As described, a network node may provide a UE with a DRX configuration for an access link between the UE and the network node to save battery life or otherwise reduce power consumption of the UE.

[0123] In some cases, a UE may be configured to communicate with another UE via a side link. Therefore, in some cases, a UE may be configured to perform DRX operations on the side link. For example, Figure 6 In sidelink communications, UE 120-1 may transmit sidelink communications to UE 120-2, and UE 120-1 may provide a sidelink DRX configuration to UE 120-2. Furthermore, in sidelink communications, transmissions between each UE pair are bidirectional, whereby each UE may be both a transmitter UE and a receiver UE.

[0124] like Figure 6 As shown, UE 120 may perform sidelink DRX operations in various sidelink connectivity modes, such as a sidelink connected mode (e.g., RRC connected mode on one or more sidelinks) and / or a sidelink idle mode (e.g., RRC idle mode). In some aspects, UE 120 may perform sidelink DRX operations in other sidelink connectivity modes, such as a sidelink inactive mode (e.g., RRC inactive mode on one or more sidelinks).

[0125] like Figure 6 As further shown, UE 120 may initiate sidelink DRX operation based on expiration of a sidelink DRX inactivity timer. In some aspects, UE 120 may initiate sidelink DRX operation before expiration of the sidelink DRX inactivity timer, such as based on expiration of the sidelink DRX inactivity timer (e.g., which may cause UE 120 to transition from a sidelink connected mode to a sidelink idle mode) and / or based on operation of another UE.

[0126] In some aspects, UE 120 may determine whether the sidelink DRX inactivity timer has expired based on a duration of time since the last transmission and / or reception of sidelink communications by UE 120. For example, UE 120 may determine that the sidelink DRX inactivity timer has expired based on no transmission and / or reception of sidelink communications during the duration of time and / or based on an amount of sidelink communications transmitted and / or received during the duration of time that fails to meet a threshold.

[0127] Similarly, UE 120 may determine whether the sidelink inactivity timer has expired based on a duration of time since UE 120 last transmitted and / or last received a sidelink communication. The duration of time associated with the sidelink inactivity timer may be different (e.g., longer) than the duration of time associated with the sidelink DRX inactivity timer. For example, UE 120 may determine that the sidelink inactivity timer has expired based on not transmitting and / or not receiving sidelink communications during the duration of time and / or based on transmitting and / or receiving an amount of sidelink communications that fails to meet a threshold during the duration of time.

[0128] like Figure 6As further shown, UE 120 may perform sidelink DRX operations based on a sidelink DRX cycle. The sidelink DRX cycle may include a combination of a sidelink DRX on duration and a sidelink DRX sleep state. UE 120 may operate in the sidelink DRX sleep state during the sidelink DRX sleep duration or the inactivity time. In the sidelink DRX sleep state, UE 120 may avoid transmitting or receiving on the sidelink, may deactivate specific subcarriers or component carriers of the sidelink (e.g., when carrier aggregation is implemented on the sidelink), and / or may deactivate one or more components of UE 120, etc. In addition, UE 120 may operate in a sidelink DRX on mode within the sidelink DRX on duration to monitor sidelink communications from other UEs and / or send sidelink communications to other UEs. The combination of the sidelink DRX sleep duration and the sidelink DRX on duration may be referred to as the sidelink DRX cycle duration of the sidelink DRX cycle. On the other hand, a UE 120 in the sidelink DRX sleep state may be active on the access link for uplink transmission and / or downlink reception. The UE 120 may also use the sidelink for other purposes, such as additional measurements and / or testing.

[0129] like Figure 6 As further shown, the sidelink DRX operation of the UE 120 may include various types of sidelink DRX cycles, such as a short sidelink DRX cycle and / or a long sidelink DRX cycle. The sidelink DRX cycle duration of the short sidelink DRX cycle may be shorter relative to the sidelink DRX cycle duration of the long sidelink DRX cycle. For example, the short DRX cycle duration may be five (5) subframes, while the long DRX cycle duration may be ten (10) subframes. In some aspects, the UE 120 may transition from the short sidelink DRX cycle to the long sidelink DRX cycle based on not transmitting and / or not receiving sidelink communications for a specific amount of consecutive sidelink DRX on mode durations.

[0130] In some aspects, the sidelink DRX cycle duration, the sidelink DRX on duration, and / or the sidelink DRX sleep duration of the sidelink DRX operation of the UE 120 may be the same or different between the sidelink connected mode and the sidelink idle mode. For example, the sidelink DRX sleep mode duration may be longer in the sidelink idle mode relative to the sidelink connected mode, in which case fewer sidelink DRX on durations may be scheduled for a given time period in the sidelink idle mode relative to the sidelink connected mode.

[0131] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0132] Figure 7A7 is a diagram illustrating an example 700 of network DRX and discontinuous transmission (DTX) according to the present disclosure. Figure 7A As shown, example 700 includes UE 120 communicating with network node 110. In some examples, UE 120 may be in a connected state with network node 110 (e.g., an RRC connected state).

[0133] Network DRX / DTX (which may also be referred to as cell DRX / DTX) may be implemented by restricting the UE 120 from transmitting and / or receiving specific (e.g., configured) uplink channels and / or downlink channels during the inactive time of the DRX cycle. For example, in the uplink, RACH communications, scheduling requests, and / or configured grant communications may be restricted. As another example, in the downlink, system information communications, SPS communications, and / or CSI-RS for RRM or RLM may be restricted. Therefore, if the UE 120 knows when to enable restrictions on transmission and / or reception, explicit definition and configuration for network DRX / DTX (e.g., on / off duration, inactivity timer, etc.) may not be required. For example, network DRX / DTX may be used in conjunction with Figure 5 The described DRX framework and one or more defined transmission and / or reception restriction rules for one or more uplink and / or downlink channels (e.g., preconfigured uplink and / or downlink channels) during DRX inactivity time.

[0134] As shown by reference numeral 705, the network node 110 may send an indication (skip indication) that the UE 120 will skip (e.g., drop) transmission and / or reception during the DRX inactivity time, and the UE 120 may receive an indication (skip indication) that the UE 120 will skip (e.g., drop) transmission and / or reception during the DRX inactivity time. For example, the UE 120 may receive an indication to enable (or relax) transmission and reception (i.e., uplink and downlink) restrictions. The indication may be in a DCI, in a MAC-CE, or in RRC signaling. In some examples, the indication may be associated with (e.g., tied to) a DRX switch indication.

[0135] like Figure 7A As shown, prior to the indication, UE 120 may send and / or receive communications 710 subject to the indication during the DRX active time (e.g., during the DRX on duration) and the DRX inactive time of the DRX cycle. For example, UE 120 may monitor and / or receive SPS communications (if configured). For another example, UE 120 may send configured grant communications (if configured).

[0136] Following the indication, the UE 120 may transmit and / or receive restricted communications 710 subject to the indication during the DRX active time of the DRX cycle (e.g., during the DRX on duration), but not during the DRX inactive time. That is, the UE 120 may skip transmitting and / or receiving restricted communications 710 during the DRX inactive time. For example, during the DRX inactive time of the DRX cycle, the UE 120 may not monitor and may not receive SPS communications. For another example, during the DRX inactive time of the DRX cycle, the UE 120 may not transmit configured grant communications.

[0137] Therefore, to achieve power savings, the network node 110 may not transmit and / or receive any downlink and / or uplink signals or channels during the DRX inactive time of the DRX cycle. However, such relaxation in transmission and / or reception may affect the overall performance in the wireless network, such as in relation to time and frequency tracking, beam management (e.g., P2 beam management and / or P3 beam management), RLM and / or BFD. For example, the UE 120 may use the CSI-RS during the DRX inactive time of the DRX cycle to perform time and frequency tracking, beam management, RLM and / or BFD to identify a suitable receive beam for receiving PDCCH communications in a subsequent DRX on duration, as long as the CSI-RS is periodically transmitted. Otherwise, the UE 120 will wait for a CSI-RS opportunity that falls within the DRX on duration to perform time and frequency tracking, beam management, RLM and / or BFD, which may affect the timing of receiving PDCCH communications and the overall data communication latency.

[0138] Some techniques and apparatus described herein enable a UE 120 to receive and measure reference signals during DRX inactivity time. For example, in some aspects, the UE 120 may receive and measure reference signals during DRX inactivity time even if the UE 120 has received an indication to skip transmission and / or reception during the DRX inactivity time. In some aspects, the UE 120 may send an indication (measurement indication) that the UE 120 is performing (e.g., that the UE 120 is capable of performing) measurements of reference signals during the DRX inactivity time (this may provide an exception to the skip indication). In response to the indication, the network node 110 may send reference signals to the UE 120 during the DRX inactivity time, and the UE 120 may receive and measure the reference signals during the DRX inactivity time. In this manner, delays in performing time and frequency tracking, beam management, BFD, and / or RLM may be reduced, thereby improving data communication latency and overall performance of communications for the UE 120.

[0139] As indicated above, Figure 7A are provided as examples. Other examples can be found in the Figure 7AThe examples described are different.

[0140] Figure 7B 7 is a diagram illustrating an example 750 of network DRX and DTX according to the present disclosure. Figure 7B As shown, example 700 includes multiple UEs 120 (shown as UE 120-1, UE 120-2, and UE 120-n) in a cell communicating with network node 110. In some examples, UE 120 may be in a connected state (e.g., an RRC connected state) with network node 110.

[0141] like Figure 7B As shown, because UE 120 is configured with different DRX inactivity timer (e.g., drx-InactivityTimer) durations (shown as Inactivity Timer 1 and Inactivity Timer 2) and / or because UE 120 starts the corresponding DRX inactivity timer at different times depending on the timing of PDCCH reception at UE 120, UE 120 may perform DRX with corresponding DRX activity times (e.g., not completely overlapping in time). Therefore, the time duration 755 during which network node 110 may drop transmission and / or reception (e.g., according to a skip indication that UE 120 skips transmission and / or reception during the DRX inactivity time) may correspond to the temporal overlap of DRX inactivity times across all UEs 120 (e.g., operating in connected mode) in a cell, rather than an individual inactivity time for each UE 120. This time duration 755 may be referred to as an uplink and / or downlink channel restriction duration. However, UE 120 may lack information about the DRX inactivity times of other UEs 120. Therefore, even if network node 110 is not in sleep state, UE 120 may skip transmission and / or reception during the DRX inactivity time according to the skip indication, thereby delaying communication at UE 120 and affecting overall communication latency (e.g., for all channels during the DRX inactivity time).

[0142] Some techniques and apparatus described herein facilitate indicating a time duration 755 of DRX inactivity time in which an indication to skip transmission and / or reception during the DRX inactivity time is applicable. Thus, the UE 120 can continue to communicate with the network node 110 during the DRX inactivity time outside of the time duration 755, regardless of the skip indication. In this way, delays in the UE's communications can be reduced, thereby improving data communication latency and overall performance of the UE 120 communications.

[0143] As indicated above, Figure 7B are provided as examples. Other examples can be found in the Figure 7B The examples described are different.

[0144] Figure 8 is a diagram of an example 800 associated with communication skipping in DRX according to the present disclosure. Figure 8 As shown, a network node (e.g., network node 110, CU, DU, and / or RU) may communicate with a UE (e.g., UE 120). In some aspects, the network node and the UE may be part of a wireless network (e.g., wireless network 100). The UE and the network node may be in communication with each other. Figure 8 The operations shown are performed after a wireless connection has been established.

[0145] As indicated by reference numeral 805, the network node may send configuration information, and the UE may receive the configuration information. In some aspects, the UE may receive the configuration information via one or more of RRC signaling, one or more MAC CEs, and / or DCI, etc. In some aspects, the configuration information may include an indication of one or more configuration parameters for the UE to select (e.g., known to the UE and / or previously indicated by the network node or other network device) and / or explicit configuration information for the UE to configure the UE, etc.

[0146] In some aspects, the configuration information may indicate a DRX configuration (e.g., a C-DRX configuration) for the UE, as described herein. Additionally or alternatively, the configuration information may indicate one or more reference signal resource (e.g., CSI-RS resource) sets for the UE, as described herein. For example, reference signal resources may be used in conjunction with time and frequency tracking, beam management, BFD and / or RLM, etc. Additionally or alternatively, the configuration information may indicate one or more transmit and / or receive restriction (or relaxation) rules for DRX inactivity time (e.g., the rule may indicate that the UE will not receive SPS communications or CSI-RS), as described herein. The UE may configure itself based at least in part on the configuration information. In some aspects, the UE may be configured to perform one or more operations described herein based at least in part on the configuration information.

[0147] As shown in reference numeral 810, the UE may perform DRX operation (e.g., C-DRX operation) according to the DRX configuration, as described herein. As shown in reference numeral 815, the network node may send an indication to skip (e.g., discard) transmission and / or reception during one or more DRX inactivity times of one or more DRX cycles, and the UE may receive an indication to skip (e.g., discard) transmission and / or reception during one or more DRX inactivity times of one or more DRX cycles. For example, the indication may implement a restriction (or relaxation) of uplink and / or downlink communications (e.g., the indication may implement one or more of the rules configured for the UE). The indication may be provided in a DCI, in a MAC-CE, or in RRC signaling. In some contexts, the time duration to which the indication applies may be referred to as an inactive duration, inactive time duration, or inactive period of cell DTX and / or cell DRX. In some contexts, the time duration may be referred to as being outside the active duration of cell DTX and / or cell DRX.

[0148] As indicated by reference numeral 820, the UE may send an indication that the UE performs measurements of one or more reference signals (e.g., SSBs and / or CSI-RS, etc.) during one or more DRX inactive times of one or more DRX cycles, and the network node may receive an indication that the UE performs measurements of one or more reference signals (e.g., SSBs and / or CSI-RS, etc.) during one or more DRX inactive times of one or more DRX cycles. For example, the indication may instruct the UE to perform measurements of reference signals during the DRX inactive times. The indication may instruct the UE to perform measurements for at least one of time and frequency tracking, beam management, BFD, and / or RLM. In some aspects, the indication may be in a UE capability information message. As an example, the UE may report whether the UE measures periodic or semi-persistent CSI-RS during the C-DRX inactive times for time and frequency tracking, beam management, BFD, and / or RLM (e.g., as part of the UE capabilities).

[0149] The UE may provide an indication of the UE performing measurements after or before receiving an indication to skip (e.g., drop) transmission and / or reception. For example, the indication of the UE performing measurements may indicate an exception to the indication to skip transmission and / or reception.

[0150] In some aspects, the indication that the UE is to perform measurements may identify one or more reference signal resources on which the UE is to perform measurements of one or more reference signals. For example, the indication may identify one or more reference signal resources from a reference signal resource set (e.g., a configured reference signal resource set) on which the UE is to perform measurements. For example, the UE may report the CSI-RS resources from the configured CSI-RS resources on which the UE is to perform measurements for time and frequency tracking, beam management, BFD, and / or RLM. That is, the UE may provide UE assistance to the network node.

[0151] As indicated by reference numeral 825, in response to an indication that the UE is performing measurements, the network node may transmit one or more reference signals (e.g., reference signal transmission) during a DRX inactive time (e.g., one or more DRX inactive times) of a DRX cycle (e.g., one or more DRX cycles), and the UE may receive one or more reference signals (e.g., reference signal transmission) during a DRX inactive time (e.g., one or more DRX inactive times) of a DRX cycle (e.g., one or more DRX cycles). For example, if the UE measures a reference signal (e.g., CSI-RS) during a DRX inactive time (e.g., during an inactive time of C-DRX for time and frequency tracking, beam management, BFD, and / or RLM), the UE may receive the reference signal. The reference signal may include an SSB, a CSI-RS, and / or a positioning reference signal, among others. For example, the reference signal may include a periodic CSI-RS (e.g., configured by RRC) and / or a semi-persistent CSI-RS (e.g., configured by MAC-CE).

[0152] In some aspects, the reference signal may correspond to all reference signal opportunities (e.g., reference signal transmission opportunities or reference signal reception opportunities) that temporally overlap with the DRX inactive time (e.g., configured to occur during the DRX inactive time) (e.g., the reference signal may be transmitted or received during these all reference signal opportunities). For example, the network node may not drop reference signal (e.g., CSI-RS) transmission during the DRX inactive time (e.g., during the C-DRX inactive time). In other words, the UE may assume that the reference signal (e.g., CSI-RS) during the inactive time is transmitted as configured. This may be referred to herein as a first drop operation.

[0153] A "reference signal opportunity" may refer to a time resource in which a reference signal is configured or scheduled to be communicated. As used herein, a "reference signal transmission opportunity" may refer to a reference signal opportunity from the perspective of a network node, and a "reference signal reception opportunity" may refer to a reference signal opportunity from the perspective of a UE.

[0154] In some aspects, a reference signal may correspond to a subset (e.g., a true subset) of reference signal opportunities (e.g., reference signal transmission opportunities or reference signal reception opportunities) (e.g., a reference signal may be transmitted or received in the subset), which subset is less than all reference signal opportunities that temporally overlap with a DRX inactive time (e.g., are configured to occur during the DRX inactive time). For example, the network node may drop a subset of reference signal (e.g., CSI-RS) transmissions during the DRX inactive time (e.g., during the C-DRX inactive time). This may be referred to herein as a second dropping operation. For example, the network node may drop every odd-indexed reference signal opportunity or every even-indexed reference signal opportunity (e.g., the reference signal opportunities may be downsampled by 2). In some aspects, the subset of reference signal opportunities may be referenced starting from the first reference signal opportunity after the end of the DRX active time of the DRX cycle. For example, the reference opportunity used to identify the subset of reference signal opportunities may be the first reference signal opportunity after the end of the DRX active time of the DRX cycle. For example, the reference for down-sampling the reference signal opportunity may be the first reference signal opportunity (eg, CSI-RS opportunity) after the end of the DRX active time.

[0155] In some aspects, a network node may transmit information identifying a subset of reference signal opportunities, and a UE may receive the information identifying the subset of reference signal opportunities. For example, the information may identify the reference signal opportunities in the subset and / or may identify a pattern of reference signal opportunities forming the subset. For example, the downsampled reference signal opportunities or the pattern identifying the downsampled reference signal opportunities may be indicated by the network node. In some aspects, the UE may identify the downsampled reference signal opportunities or the pattern identifying the downsampled reference signal opportunities according to a fixed rule.

[0156] In some aspects, the reference signal may correspond to a reference signal opportunity (e.g., a reference signal transmission opportunity or a reference signal reception opportunity) within a specific time interval before the start of the DRX-on duration of a subsequent DRX cycle (e.g., the reference signal may be transmitted or received during this reference signal opportunity). For example, the UE may assume that reference signal opportunities (e.g., CSI-RS opportunities) within X symbols or time slots before the start of the DRX-on duration are not discarded, where X may be an integer greater than zero. This may be referred to herein as a third discard operation. In some aspects, the duration of the specific time interval may be based on the subcarrier spacing (SCS) of the active downlink bandwidth part (BWP) used for one or more reference signals. For example, the SCS used to determine the symbol or time slot duration may be based at least in part on the SCS of the active downlink BWP in which the reference signal (e.g., CSI-RS) is measured.

[0157] In some aspects, the UE may not provide an indication regarding whether the UE performs reference signal measurements during DRX inactivity time. For example, the UE may not provide a report on whether the UE measures periodic or semi-persistent CSI-RS for time and frequency tracking, beam management, BFD, and / or RLM during DRX inactivity time in C-DRX. If the UE does not provide this indication, one of the first, second, or third drop operations may be used by default (e.g., one of the first, second, or third drop operations may be assumed).

[0158] As shown by reference numeral 830, the UE may perform measurements of reference signals (e.g., CSI-RS). For example, the measurements may be signal strength measurements (e.g., L1 RSRP measurements). The UE may perform reference signal measurements in conjunction with time and frequency tracking, beam management, BFD, and / or RLM, as described herein. By using an indication that the UE performs reference signal measurements during DRX inactivity time, delays in performing time and frequency tracking, beam management, BFD, and / or RLM may be reduced, thereby improving data communication latency and overall performance of UE communications.

[0159] In some aspects, the techniques described herein may be performed in conjunction with sidelink DRX. For example, in sidelink DRX, the communications between a UE and a network node as described herein may instead be between a first UE and a second UE that have established a connection on the sidelink.

[0160] As indicated above, Figure 8 are provided as examples. Other examples can be found in the Figure 8 The examples described are different.

[0161] Figure 9A is a diagram of an example 900 associated with communication skipping in DRX according to the present disclosure. Figure 9A As shown, example 900 includes a UE and a network node, such as in conjunction with Figure 8 UE and network nodes described.

[0162] As indicated by reference numeral 905, the UE may send an indication that the UE performs measurement of one or more reference signals (e.g., SSB and / or CSI-RS, etc.) during the DRX inactive time, and the network node may receive an indication that the UE performs measurement of one or more reference signals (e.g., SSB and / or CSI-RS, etc.) during the DRX inactive time, as described in conjunction with Figure 8 As shown in reference numeral 910, the network node may send one or more reference signals in the DRX inactive time of the DRX cycle, and the UE may receive one or more reference signals in the DRX inactive time of the DRX cycle, as shown in conjunction with Figure 8described.

[0163] In example 900, the reference signal may correspond to all reference signal opportunities (e.g., reference signal transmission opportunities or reference signal reception opportunities) configured during the DRX inactivity time (e.g., the reference signal may be transmitted or received during these all reference signal opportunities) (the first discarding operation described herein). For example, the network node may not discard (as indicated by the reference signal opportunities shown as solid lines) any reference signal transmissions configured during the DRX inactivity time. As indicated by reference numeral 915, the UE may perform measurements of the received reference signal for time and frequency tracking, beam management, BFD, and / or RLM.

[0164] As indicated above, Figure 9A are provided as examples. Other examples can be found in the Figure 9A The examples described are different.

[0165] Figure 9B is a diagram of an example 920 associated with communication skipping in DRX according to the present disclosure. Figure 9B As shown, example 920 includes a UE and a network node, such as in conjunction with Figure 8 UE and network nodes described.

[0166] As indicated by reference numeral 925, the UE may send an indication that the UE performs measurement of one or more reference signals (e.g., SSB and / or CSI-RS, etc.) during the DRX inactive time, and the network node may receive an indication that the UE performs measurement of one or more reference signals (e.g., SSB and / or CSI-RS, etc.) during the DRX inactive time, as described in conjunction with Figure 8 As shown in reference numeral 927, the network node may send information identifying a subset of reference signal opportunities, and the UE may receive information identifying a subset of reference signal opportunities. As shown in reference numeral 930, the network node may send one or more reference signals in the DRX inactive time of the DRX cycle, and the UE may receive one or more reference signals in the DRX inactive time of the DRX cycle, as shown in conjunction with Figure 8 described.

[0167] In example 920, the reference signal may correspond to a subset of all reference signal opportunities (e.g., reference signal transmission opportunities or reference signal reception opportunities) configured in the DRX inactive time (e.g., the reference signal may be transmitted or received in the subset of all reference signal opportunities) (a second discarding operation, as described herein). For example, the network node may discard (illustrated by the reference signal opportunities shown as dashed lines) a subset of the reference signal transmissions configured in the DRX inactive time, and the network node may not discard (illustrated by the reference signal opportunities shown as solid lines) another subset of the reference signal transmissions configured in the DRX inactive time. In addition, as shown, the reference opportunity used to determine the reference signal opportunity in which the reference signal transmission is to be discarded may be the first reference signal opportunity (which may have an index of 0) after the end of the DRX active time of the DRX cycle. For example, as shown, the reference signal transmission may be discarded in odd-indexed reference signal opportunities. As indicated by reference numeral 935, the UE may perform measurements of the received reference signal for time and frequency tracking, beam management, BFD, and / or RLM.

[0168] As indicated above, Figure 9B are provided as examples. Other examples can be found in the Figure 9B The examples described are different.

[0169] Figure 9C is a diagram of an example 940 associated with communication skipping in DRX according to the present disclosure. Figure 9C As shown, example 940 includes a UE and a network node, such as in conjunction with Figure 8 UE and network nodes described.

[0170] As indicated by reference numeral 945, the UE may send an indication that the UE performs measurements of one or more reference signals (e.g., SSB and / or CSI-RS, etc.) during the DRX inactive time, and the network node may receive an indication that the UE performs measurements of one or more reference signals (e.g., SSB and / or CSI-RS, etc.) during the DRX inactive time, as described in conjunction with Figure 8 As shown in reference numeral 950, the network node may send one or more reference signals in the DRX inactive time of the DRX cycle, and the UE may receive one or more reference signals in the DRX inactive time of the DRX cycle, as shown in conjunction with Figure 8 described.

[0171] In example 940, the reference signal may correspond to a reference signal opportunity (e.g., a reference signal transmission opportunity or a reference signal reception opportunity) within a specific time interval (e.g., an amount of symbols and / or time slots) before the start of the DRX On duration of a subsequent DRX cycle (e.g., the reference signal may be transmitted or received in the reference signal opportunity). For example, the network node may discard reference signal transmissions in reference signal opportunities before the specific time interval (illustrated by reference signal opportunities in dashed lines), and the network node may not discard reference signal transmissions in reference signal opportunities within the specific time interval (illustrated by reference signal opportunities in solid lines). As indicated by reference numeral 955, the UE may perform measurements of the received reference signal for time and frequency tracking, beam management, BFD, and / or RLM.

[0172] As indicated above, Figure 9C are provided as examples. Other examples can be found in the Figure 9C The examples described are different.

[0173] Figure 10 is a diagram of an example 1000 associated with communication skipping in DRX according to the present disclosure. Figure 10 As shown, a network node (e.g., network node 110, CU, DU, and / or RU) may communicate with a UE (e.g., UE 120). In some aspects, the network node and the UE may be part of a wireless network (e.g., wireless network 100). The UE and the network node may be in communication with each other. Figure 10 The operations shown are performed after a wireless connection has been established.

[0174] As shown at 1005, the network node may be combined with Figure 8 The configuration information is sent in a similar manner as described above, and the UE can be combined with Figure 8 Configuration information is received in a manner similar to that described above. For example, the configuration information may indicate a DRX configuration for the UE (e.g., a C-DRX configuration), one or more reference signal resource (e.g., CSI-RS resource) sets for the UE, and / or one or more transmission and / or reception restriction (or relaxation) rules for DRX inactivity time.

[0175] Additionally or alternatively, the configuration information may identify a time duration of a DRX inactivity time of a DRX cycle (which may be referred to as an uplink and / or downlink channel restriction duration). The time duration may be used to apply an indication to skip transmission and / or reception during the DRX inactivity time. For example, during the time duration, an indication to skip transmission and / or reception may be applicable. For example, the UE may be configured with a time duration in which restriction rules for uplink / downlink channel transmission / reception at the UE are applied. In some aspects, the configuration information may also indicate the periodicity of the time duration. For example, the time duration may be periodic (e.g., the configuration information provides the time duration and the periodicity of the time duration). The time duration may be indicated in milliseconds, or as an amount of time slots and / or symbols. In some contexts, the time duration may be referred to as an inactivity duration of cell DTX and / or cell DRX, an inactivity time duration, or an inactivity period. In some contexts, the time duration may be referred to as being outside the activity duration of cell DTX and / or cell DRX.

[0176] As shown at 1010, the UE may perform DRX operation (e.g., C-DRX operation) according to the DRX configuration, as described herein. As shown at 1015, the network node may be combined with Figure 8 In a similar manner as described above, an indication to skip (e.g., drop) transmission and / or reception during the DRX inactivity time is sent, and the UE may combine the Figure 8 A similar manner as described is described for receiving an indication to skip (eg, drop) transmission and / or reception during DRX inactivity time.

[0177] As indicated by reference numeral 1020, the network node may transmit a communication indicating activation for a time duration of at least a DRX cycle (e.g., one or more DRX cycles), and the UE may receive a communication indicating activation for a time duration of at least a DRX cycle (e.g., one or more DRX cycles). For example, the time duration may be triggered by the communication in an aperiodic manner and / or a semi-persistent manner. In some aspects, the communication may be, or may include, an indication to skip transmission and / or reception. For example, the time duration may be triggered based at least in part on the indication (e.g., an uplink / downlink channel restriction indication).

[0178] As indicated by reference numeral 1025, the UE and the network node may communicate during the time duration according to the indication to skip transmission and / or reception. For example, the UE and the network node may communicate during the DRX cycle according to the indication during the time duration. For example, during the DRX cycle, the UE and the network node may communicate during the DRX active time, and / or the UE and the network node may communicate during the DRX inactive time outside the time duration (or within the time duration, as long as the communication is not affected by the indication to skip transmission and / or reception). In addition, the network node and the UE may skip transmission and / or reception according to the indication during the time duration. In a similar manner, the UE and the network node may communicate in multiple DRX cycles according to the time duration (for example, if the time duration is periodic or semi-persistent).

[0179] In some aspects, a portion of the time duration may overlap with a DRX active time of a DRX cycle. In this case, communicating during the DRX cycle in accordance with the indication during the time duration may include sending or receiving communications during the portion of the time duration that overlaps with the DRX active time without applying the indication (e.g., regardless of the indication). For example, when the time duration overlaps with the DRX active time of the UE, uplink / downlink channel restriction rules may not apply (e.g., may be ignored) if uplink or downlink channels are to be sent or received during the overlapping portion of the time duration.

[0180] In this manner, the network node's DRX / DTX sleep state may be maintained during a time duration in which all UEs in the network node's cell are in the DRX inactivity time. Consequently, the UE may continue to communicate with the network node during the DRX inactivity time outside of the time duration, regardless of instructions to skip transmission and / or reception. In this manner, latency in UE communications may be reduced, thereby improving data communication latency and overall performance of UE communications.

[0181] As indicated above, Figure 10 are provided as examples. Other examples can be found in the Figure 10 The examples described are different.

[0182] Figure 11 1 is a diagram of an example 1100 associated with communication skipping in DRX according to the present disclosure. Example 1100 includes a first UE (e.g., UE 120), shown as UE-1, and a second UE (e.g., UE 120), shown as UE-2. The first UE and the second UE may be in connected mode in the same cell. The first UE and the second UE may be performing DRX operation (e.g., according to the same DRX configuration), as described herein.

[0183] As indicated by reference numeral 1105, the first UE may receive an indication to skip transmission and / or reception during the DRX inactivity time (e.g., an uplink / downlink channel restriction indication), as described herein. As indicated by reference numeral 1110, the first UE may receive a first PDCCH communication intended for the first UE at a first time within the DRX On duration of the DRX cycle. As indicated by reference numeral 1115, the second UE may receive a second PDCCH communication intended for the second UE at a second time (e.g., later than the first time) within the DRX On duration of the DRX cycle.

[0184] As shown in reference numeral 1120, the first UE may start a first DRX inactivity timer upon receiving a first PDCCH communication. As shown in reference numeral 1125, the second UE may start a second DRX inactivity timer upon receiving a second PDCCH communication. Thus, the first DRX inactivity timer and the second DRX inactivity timer may be started at different times. Furthermore, as shown in the figure, the second DRX inactivity timer may run for a longer time than the first DRX inactivity timer. In other words, the first DRX inactivity timer and the second DRX inactivity timer may terminate at different times. Thus, the first UE and the second UE may have different inactivity times in the DRX cycle.

[0185] As described herein, the first UE and the second UE may be configured with a time duration 1130 in which an indication to skip transmission and / or reception during the DRX inactive time is applicable. For example, as shown, the time duration 1130 may correspond to an overlap of the inactive time of the first UE and the inactive time of the second UE. Thus, during the DRX inactive time, the first UE may apply the indication to skip transmission and / or reception during the time duration 1130 (e.g., but not outside the time duration 1130). As shown, the time duration 1130 may be repeated in the DRX cycle according to the periodicity of the time duration 1130. In some aspects, a portion of the time duration 1130 may overlap with the DRX active time of the DRX cycle. During this portion of the time duration 1130, the first UE may send or receive communications without applying the indication.

[0186] As indicated above, Figure 11 are provided as examples. Other examples can be found in the Figure 11 The examples described are different.

[0187] Figure 12 is a diagram illustrating an example process 1200, performed, for example, by a UE, according to the present disclosure. Example process 1200 is an example in which a UE (eg, UE 120) performs operations associated with communication skipping in DRX.

[0188] like Figure 12 As shown, in some aspects, process 1200 may include sending a first indication that the UE performs measurements of one or more reference signals during one or more DRX inactivity times of one or more DRX cycles (block 1210). Figure 16 The depicted communications manager 140 and / or transmitting component 1604) may transmit a first indication that the UE perform measurements of one or more reference signals during one or more DRX inactivity times of one or more DRX cycles, as described above.

[0189] In some aspects, process 1200 may include (e.g., optionally, as shown in dashed lines) receiving a second indication to skip at least one of transmission or reception during one or more DRX inactivity times of one or more DRX cycles (block 1212). Figure 16 The communication manager 140 and / or receiving component 1602 as depicted may receive a second indication to skip at least one of transmission or reception during one or more DRX inactivity times of one or more DRX cycles, as described above. In some aspects, process 1200 may include (e.g., optionally, as shown in dashed lines) receiving information identifying a subset of reference signal opportunities (block 1214). For example, a UE (e.g., using Figure 16 The depicted communications manager 140 and / or receiving component 1602) can receive information identifying a subset of reference signal opportunities, as described above.

[0190] like Figure 12 As further shown, in some aspects, process 1200 may include, in response to the first indication, receiving one or more reference signals during a DRX inactivity time in one or more DRX inactivity times in the one or more DRX cycles (block 1220). Figure 16 The depicted communications manager 140 and / or receiving component 1602) may receive one or more reference signals during a DRX inactivity time in one or more DRX inactivity times in one or more DRX cycles in response to the first indication, as described above.

[0191] Process 1200 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0192] In the first aspect, process 1200 also includes receiving a second indication to skip at least one of transmission or reception during one or more DRX inactivity times of the one or more DRX cycles.

[0193] In a second aspect, alone or in combination with the first aspect, the one or more reference signals include at least one of an SSB, a CSI-RS, or a positioning reference signal.

[0194] In a third aspect, alone or in combination with one or more of the first and second aspects, the one or more reference signals include a periodic CSI-RS.

[0195] In a fourth aspect, alone or in combination with one or more of the first to third aspects, the one or more reference signals include a semi-persistent CSI-RS.

[0196] In a fifth aspect, alone or in combination with one or more of aspects 1 to 4, the indication indicates that the UE is configured to perform measurements of one or more reference signals for at least one of time and frequency tracking, beam management, radio link monitoring, or beam failure detection.

[0197] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, the one or more reference signals correspond to all reference signal opportunities that temporally overlap with the DRX inactivity time.

[0198] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, the one or more reference signals correspond to a subset of reference signal occasions that temporally overlap with a DRX inactivity time.

[0199] In an eighth aspect, alone or in combination with one or more of the first to seventh aspects, the subset of reference signal opportunities is referenced starting from a first reference signal opportunity after an end of a DRX active time of a DRX cycle.
