Technical Field

[0002]

[0006] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for channel state information (CSI) reporting across discontinuous reception (DRX) groups. Background Art

[0003] Wireless communication systems are widely deployed to provide a variety of telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support 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 released by the Third Generation Partnership Project (3GPP).

[0004] A wireless network may include multiple base stations (BSs), which may support communications for multiple user equipments (UEs). A UE may communicate with a BS via a downlink and an uplink. A downlink (or forward link) refers to a communication link from a BS to a UE, and an uplink (or reverse link) refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0005] The above multiple access technology has been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a city-wide, national-wide, regional-wide, and even global scale. NR (which may also be referred to as 5G) is a set of enhancements to the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL) Better integration, and 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 are still useful. Summary of the invention

[0006] In some aspects, a method of wireless communication performed by a user equipment may include determining whether a flag is enabled or disabled, the flag indicating whether channel state information (CSI) associated with a secondary discontinuous reception (DRX) group is allowed to be sent outside of an active time associated with a primary DRX group; and selectively sending CSI associated with the secondary DRX group in uplink communications associated with the primary DRX group based at least in part on whether the flag is enabled or disabled.

[0010] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a UE, may cause the one or more processors to determine whether a flag is enabled or disabled, the flag indicating whether CSI associated with a secondary DRX group is allowed to be sent outside of an active time associated with a primary DRX group; and selectively send CSI associated with the secondary DRX group in uplink communications associated with the primary DRX group based at least in part on whether the flag is enabled or disabled.

[0011] In some aspects, a non-transitory computer-readable medium may store one or more instructions for wireless communication. The one or more instructions, when executed by one or more processors of a UE, may cause the one or more processors to determine that CSI associated with a secondary DRX group will be multiplexed with UCI outside of an active time associated with a primary DRX group; and send uplink communications in a PUCCH associated with the primary DRX group based at least in part on determining that the CSI will be multiplexed with UCI outside of an active time associated with the primary DRX group, wherein the uplink communications include at least the CSI associated with the secondary DRX group.

[0012] In some aspects, an apparatus for wireless communications may include a unit for determining whether a flag is enabled or disabled, the flag indicating whether CSI associated with a secondary DRX group is allowed to be sent outside of an active time associated with a primary DRX group; and a unit for selectively sending CSI associated with the secondary DRX group in uplink communications associated with the primary DRX group based at least in part on whether the flag is enabled or disabled.

[0023] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in a variety of different forms, and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the protection scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the protection 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 present disclosure. For example, a device can be implemented or a method can be practiced using any number of aspects set forth herein. In addition, the protection scope of the present disclosure is intended to cover such a device or method that is practiced using other structures, functions, or structures and functions of various aspects of the disclosure set forth herein, or structures and functions of various aspects of the disclosure set forth herein that are different from those set forth herein. It should be understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements of the claims.

[0024] Several aspects of telecommunication systems are now presented with reference to various devices and techniques. These devices and techniques will be described in the detailed description below and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0025] It should be noted that while various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applicable to other RATs, such as 3G RATs, 4G RATs, and / or post-5G RATs (e.g., 6G).

[0026] Figure 11 is a schematic diagram showing an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (NR) network and / or an LTE network, etc., or may include elements of a 5G network and / or an LTE network, as well as other examples. The wireless network 100 may include a number of base stations 110 (shown as BS110a, BS110b, BS110c, and BS110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE), and may also be referred to as an NR BS, a node B, a gNB, a 5G node B (NB), an access point, a transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0027] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown, BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NRBS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0028] In some aspects, the cells are not necessarily stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces (such as direct physical connections or virtual networks) using any suitable transport network.

[0029] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown, a relay BS 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.

[0030] The wireless network 100 may be a heterogeneous network including different types of BSs, such as a macro BS, a pico BS, a femto BS, a relay BS, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0031] The network controller 130 may be coupled to a set of BSs and may provide coordination and control for the BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other, for example, directly or indirectly via a wireless backhaul or a wired backhaul communication link.

[0032] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biosensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio unit), a vehicle-mounted component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0033] Some UEs may be considered to be machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include robots, drones, remote devices, sensors, meters, monitors and / or location tags that can communicate with a base station, another device (e.g., a remote device) or some other entity. A wireless node may provide a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or a connection to the network via a wired or wireless communication link. Some UEs may be considered to be Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered to be customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (e.g., processor components and / or memory components). In some aspects, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled and / or electrically coupled.

[0034] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0035] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols or vehicle-to-infrastructure (V2I) protocols), and / or mesh networks. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein performed by base station 110.

[0036] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1), wherein FR1 can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2), wherein FR2 can span from 24.25 GHz to 52.6 GHz. Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "below 6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Therefore, unless otherwise expressly stated, it should be understood that the term "sub-6 GHz" and the like (if used herein) can broadly refer to frequencies less than 6 GHz within FR1 and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise expressly stated, it should be understood that the term "millimeter wave" and the like (if used herein) can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 can be modified, and that the techniques described herein are applicable to these modified frequency ranges.

[0037] As indicated above, Figure 1 is provided as an example. Other examples may be related to Figure 1 The examples described are different.

[0038] Figure 2 is a diagram illustrating an example 200 of base station 110 and UE 120 communicating in wireless network 100 according to the present disclosure. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≥1 and R≥1.

[0039] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols (if applicable), and provide T output symbol streams to T modulators (MOD) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0040] At the UE 120, antennas 252a to 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to the data sink 260, and 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 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, among other examples. In some aspects, one or more components of UE 120 may be included in housing 284 .

[0041] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0042] Antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, antenna element sets, and / or antenna arrays, as well as other examples. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include coplanar antenna element sets and / or non-coplanar antenna element sets. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include antenna elements within a single housing and antenna elements within multiple housings. Antenna panels, antenna groups, antenna element sets, and / or antenna arrays may include one or more antenna elements coupled to one or more transmit and / or receive components, such as Figure 2 One or more components of a

[0043] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266 (if applicable), further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted back to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein, such as those described with reference to Figure 3A , Figure 3B , Figure 4 , Figure 5 or Figure 6 As described.

[0044] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 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, such as those described with reference to Figure 3A-3B , Figure 4 , Figure 5 or Figure 6 As described.

[0045] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the UE 120 may perform one or more techniques associated with channel state information (CSI) reporting across discontinuous reception (DRX) groups, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component may perform or direct e.g. Figure 5 The process of 500 Figure 6 600 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, 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, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may perform or direct, for example, Figure 5 The process of 500 Figure 6 The operations of process 600 and / or other processes as described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among other examples.

[0046] In some aspects, the UE 120 may include means for determining whether a flag is enabled or disabled, the flag indicating whether CSI associated with the secondary DRX group is allowed to be sent outside of the active time associated with the primary DRX group; means for selectively sending CSI associated with the secondary DRX group in uplink communications associated with the primary DRX group based at least in part on whether the flag is enabled or disabled, etc. In some aspects, such means may include combining Figure 2 One or more components of the UE 120 are depicted, such as a controller / processor 280, a transmit processor 264, a TX MIMO processor 266, a MOD 254, an antenna 252, a DEMOD 254, a MIMO detector 256, a receive processor 258, and the like.

[0047] In some aspects, the UE 120 may include means for determining that CSI associated with the secondary DRX group will be multiplexed with uplink control information (UCI) outside of active times associated with the primary DRX group; and means for transmitting uplink communications in a physical uplink control channel (PUCCH) associated with the primary DRX group based at least in part on determining that the CSI will be multiplexed with UCI outside of active times associated with the primary DRX group, wherein the uplink communications include at least the CSI associated with the secondary DRX group, etc. In some aspects, such means may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0048] Although it will Figure 2 The blocks in the 200 are shown as distinct components, but the functions described above with respect to the blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by the controller / processor 280 or under the control of the controller / processor 280.

[0049] As indicated above, Figure 2 is provided as an example. Other examples may be related to Figure 2 The examples described are different.

[0050] DRX configuration is typically defined per medium access control (MAC) entity. The DRX configuration may include, for example, information associated with one or more types of DRX cycles (e.g., short and / or long), information associated with an on-duration timer (e.g., drx-onDurationTimer), information associated with an inactivity timer (e.g., drx-InactivityTimer), etc. Typically, the DRX configuration is defined using values ​​that are independent of the subcarrier spacing (SCS) (e.g., parameters of the DRX configuration may be defined in terms of milliseconds rather than the number of time slots).

[0051] In some wireless communication systems, a single DRX configuration may be configured. However, in some cases, the use of a single DRX configuration may be undesirable. For example, in a carrier aggregation scenario in an NR system, the component carriers used for wireless communication may be in different frequency ranges and have different numerologies. As a specific example, a first set of component carriers for wireless communication may be in FR1, while a second set of component carriers for wireless communication may be in FR2. In such a case, power consumption characteristics and / or latency / throughput characteristics may vary across component carriers. Therefore, when a single DRX configuration is used across these component carriers with different characteristics, the tradeoff between power savings and scheduling flexibility (latency / throughput) across component carriers is limited.

[0052] To address this issue, in some wireless communication systems, another DRX configuration may be configured (i.e., multiple DRX configurations may be configured). For example, a primary DRX configuration and a secondary DRX configuration may be configured. In such a case, one or more parameters may be different between the primary DRX configuration and the secondary DRX configuration. For example, the inactivity and on duration timers associated with the primary DRX configuration may be different from (e.g., longer than) the inactivity and on duration timers associated with the secondary DRX configuration. In a scenario where the component carriers are FR1 and FR2, the primary DRX configuration may be used for the component carriers in FR1, and the secondary DRX configuration may be used for the component carriers in FR2, so as to alleviate the limitations on the tradeoff between power saving and scheduling flexibility described above.

[0053] A set of component carriers configured using primary DRX (e.g., in FR1) may be referred to as a primary DRX group (PDG). A primary DRX group may be, for example, power efficient, and may be used for control data and relatively low rate / delay tolerant services. A set of component carriers configured using secondary DRX (e.g., in FR2) may be referred to as a secondary DRX group (Secondary DRX Group). A secondary DRX group may, for example, have high power consumption, and may be used for high rate / emergency services. In such a scenario, it is desirable that the active time associated with the secondary DRX group is shorter than the active time associated with the primary DRX group (e.g., for power saving purposes). For power efficient operation, the secondary DRX group may be used only when there is a need (e.g., remain in DRX active time), and may otherwise remain in DRX mode (e.g., outside of active time). In some cases, this can be achieved by configuring the timers associated with the secondary DRX group (e.g., drx-onDurationTimer and drx-InactivityTimer associated with the secondary DRX configuration) to be shorter than the timers associated with the primary DRX group (e.g., drx-onDurationTimer and drx-InactivityTimer associated with the primary DRX configuration).

[0054] However, if the DRX processes of the primary DRX group and the secondary DRX group are completely independent, it is not always guaranteed that the active time associated with the secondary DRX group is shorter than the active time associated with the primary DRX group. For example, even if the timer used by the secondary DRX group (e.g., the timer associated with the secondary DRX configuration) can be shorter than the timer used by the primary DRX group (e.g., the timer associated with the primary DRX configuration), the extension of the active time associated with a given DRX group (e.g., by starting / restarting the drx-InactivityTimer) depends on the traffic in the given DRX group. Since the primary DRX group can be used for signals such as paging, system information, time slot format indication, wake-up / secondary cell sleep indication, etc., as well as UCI such as CSI (e.g., when a single PUCCH configuration is to be used for all DRX groups), it is desirable to ensure that the primary DRX group is in active time at all times during which the secondary DRX group is in active time.

[0055] If the primary DRX group is not in active time at all times during which the secondary DRX group is in active time, reporting of some information such as CSI associated with the secondary DRX group may be affected, which results in secondary DRX group resources being wasted. For example, the primary DRX group and the secondary DRX group may be in the same PUCCH group (e.g., so that both DRX groups will use a single PUCCH configuration indicating PUCCH resources on cells in the primary DRX group). If the primary DRX group is in active time at all times during which the secondary DRX group is in active time, CSI determined based on measurements made at previous measurement occasions (e.g., measurement occasions within the most recent active time of the secondary DRX group) may be sent via the PUCCH in the primary DRX group. In particular, in this case, measurement occasions associated with the secondary DRX group outside of the active time associated with the secondary DRX group may not be used (i.e., measurements may not be performed). Conversely, if the primary DRX group is not in active time at a given time during which the secondary DRX group is in active time, even though measurements associated with determining CSI can be performed on the secondary DRX group during the active time associated with the secondary DRX group, CSI cannot be sent on the primary DRX group (e.g., because the primary DRX group is outside the active time), which means that resources used to perform measurements and determine CSI associated with the secondary DRX group are wasted.

[0056] Some aspects described herein provide techniques and apparatus for cross-DRX group CSI reporting. In some aspects, a UE may determine whether a flag is enabled or disabled, wherein the flag indicates whether CSI associated with a secondary DRX group is allowed to be sent outside of active time associated with a primary DRX group. In some aspects, based at least in part on whether the flag is enabled or disabled, the UE may selectively send CSI associated with a secondary DRX group in uplink communications associated with the primary DRX group.

[0057] In some aspects, to further improve power efficiency, it may be desirable to multiplex CSI associated with a secondary DRX group with other UCI when reporting CSI outside of active times associated with a primary DRX group. In some aspects, a UE may determine that CSI associated with a secondary DRX group is to be multiplexed with UCI outside of active times associated with a primary DRX group, and may send uplink communications in a PUCCH associated with the primary DRX group based at least in part on the determination. Here, the uplink communications may include at least CSI associated with the secondary DRX group. Additional details are described below.

[0058] Figure 3A and Figure 3B is a schematic diagram showing an example associated with cross-DRX group CSI reporting according to the present disclosure. Figure 3A and Figure 3B In an associated example, a UE (e.g., UE 120) is configured to use a primary DRX group associated with a primary DRX configuration (e.g., one or more component carriers in FR1) and a secondary DRX group associated with a secondary DRX configuration (e.g., one or more component carriers in FR2). Further, the primary DRX group and the secondary DRX group are associated with a single PUCCH configuration (e.g., a PUCCH configuration indicating resources to be used for providing uplink control information on cells in the primary DRX group).

[0059] As in Figure 3A As shown by reference numeral 302 in the figure, the UE may receive (e.g., from the base station 110) a configuration associated with the flag and / or an indication of enabling or disabling the flag. In some aspects, the flag is an indicator of whether to signal whether to allow information associated with the secondary DRX group to be sent at a specific time. In some aspects, the flag may be a bit indicator. As an example, in some aspects, the flag may be an indicator of whether to signal whether to allow CSI (e.g., periodic CSI, semi-persistent CSI, etc.) associated with the secondary DRX group to be sent outside the active time associated with the primary DRX group. Here, when the flag is enabled (e.g., when the bit associated with the flag is set to a value of 1), the flag may indicate that the CSI associated with the secondary DRX group is allowed to be sent outside the active time associated with the primary DRX group. Conversely, when the flag is disabled (e.g., when the bit associated with the flag is set to a value of 0), the flag may indicate that the CSI associated with the secondary DRX group is not allowed to be sent outside the active time associated with the primary DRX group.

[0060] In some aspects, the tag may be configurable per UE (e.g., a single tag may be used for all secondary DRX groups configured on the UE). Alternatively, in some aspects, the tag may be configurable per DRX group (e.g., such that different tags are used for different secondary DRX groups configured on the UE).

[0061] In some aspects, the flag may be configured based at least in part on UE capability information provided by the UE (e.g., capability information indicating that the UE supports the use of the flag). In some aspects, the flag may be configured based at least in part on a request sent by the UE (e.g., a request via auxiliary information feedback).

[0062] In some aspects, use of the flag may be conditional on a single PUCCH configuration. That is, in some aspects, use of the flag for determining whether to allow transmission of CSI associated with a secondary DRX group outside of active times associated with the primary DRX group may be conditional on the primary DRX group and the secondary DRX group being associated with a single PUCCH configuration (e.g., such that CSI associated with the secondary DRX group will be provided in PUCCH resources in the primary DRX group).

[0063] In some aspects, the UE may receive configuration of a flag or an indication associated with enabling or disabling a flag via, for example, radio resource control (RRC) signaling, MAC control element (MAC-CE), downlink control information (DCI), etc.

[0064] As indicated by reference numeral 304, the UE may determine whether the flag is enabled or disabled. In some aspects, the UE may determine whether the flag is enabled or disabled at or before a measurement occasion associated with the secondary DRX group. Further, in some aspects, the UE may determine whether the flag is enabled or disabled after determining whether an uplink communication occasion (e.g., a PUCCH occasion) associated with reporting CSI determined at least in part based on measurement results at the time of measurement is within an active time of the primary DRX group. Further, in some aspects, the UE may determine whether the flag is enabled or disabled after determining whether the primary DRX group is in active time or within a threshold amount of time from the end of active time.

[0065] For example, at a measurement opportunity with a secondary DRX group, the UE may determine whether an uplink communication opportunity (e.g., a PUCCH opportunity) associated with reporting CSI determined based at least in part on the measurement results at the measurement opportunity is within the active time of the primary DRX group (or within a threshold amount of time from the end of the active time). Here, if the uplink communication opportunity associated with the measurement opportunity is outside the active time associated with the primary DRX group (i.e., if the primary DRX group will not be in the active time when communicating uplink) and if the uplink communication opportunity associated with the measurement opportunity is within the threshold amount of time from the end of the active time associated with the primary DRX group, the UE may determine whether the flag is enabled or disabled (e.g., because in this case, CSI will need to be provided after the end of the active time associated with the primary DRX group). In some aspects, the UE may determine whether the flag is enabled or disabled based at least in part on an indication from a base station, as described above.

[0066] Continuing with the above example, if the flag is enabled (e.g., indicating that the CSI associated with the secondary DRX group may be provided outside of the active time associated with the primary DRX group), the UE may continue to perform measurements and determine the CSI associated with the secondary DRX group. Conversely, if the flag is disabled (e.g., indicating that the CSI associated with the secondary DRX group may not be provided outside of the active time associated with the primary DRX group), the UE may avoid performing measurements and determining the CSI associated with the secondary DRX group, thereby saving secondary DRX group resources. In the event that the uplink communication opportunity associated with the measurement opportunity is within the active time associated with the primary DRX group (i.e., if the primary DRX group is in the active time), the UE may skip determining whether the flag is enabled or disabled (e.g., because in this case, the CSI will be provided during the active time associated with the primary DRX group), and may continue to perform measurements and determine the CSI associated with the secondary DRX group.

[0067] As indicated by reference numeral 306, the UE may selectively transmit CSI associated with the secondary DRX group in uplink communications (eg, PUCCH communications) associated with the primary DRX group based at least in part on whether the flag is enabled or disabled.

[0068] In some aspects, when the flag is enabled, selectively sending CSI associated with the secondary DRX group in uplink communications associated with the primary DRX group includes: sending CSI in uplink communications. In some aspects, the CSI associated with the secondary DRX group may be sent during the active time associated with the secondary DRX group. That is, when the flag is enabled, if the secondary DRX group is in the active time, CSI reporting (e.g., in PUSCH) is allowed on the primary DRX group (i.e., on the PUCCH carrier) outside the active time of the primary DRX group (i.e., the PUCCH timing for CSI reporting can be extended outside the active time). In some aspects, associated with sending CSI in uplink communications (e.g., PUCCH communications), the UE may perform a wake-up associated with the primary DRX group at the PUCCH timing. In particular, outside the active time associated with the primary DRX group, the UE does not need to monitor the physical downlink control channel (PDCCH) associated with the primary DRX group, but can remain in sleep mode or low power mode.

[0069] In some aspects, when the flag is disabled, selectively sending CSI associated with the secondary DRX group in uplink communications associated with the primary DRX group can include: skipping measurement opportunities associated with determining the CSI, as described above, and / or avoiding sending CSI in uplink communications (e.g., if the CSI has already been determined).

[0070] In some aspects, the UE may further selectively send CSI in uplink communications based at least in part on a timer. The timer may indicate, for example, a maximum length of time that CSI is allowed to be reported in uplink communications after an active time associated with a primary DRX group. For example, the UE may start a timer at the end of an active time associated with the primary DRX group. Next, the UE may determine that the flag is enabled, as described above. The UE may then determine whether the timer has expired (e.g., whether a threshold amount of time has passed since the end of the active time associated with the primary DRX group). In this example, if the timer has not expired, the UE may determine the CSI associated with the secondary DRX group and send the CSI in the uplink communications associated with the primary DRX group. Conversely, if the timer has expired, the UE may skip the measurement opportunity associated with determining the CSI or avoid sending the CSI in the uplink communications associated with the primary DRX group. In such a case, the UE may also disable the flag (e.g., without an indication from the base station).

[0071] In some aspects, the UE may further selectively send CSI in uplink communications based at least in part on a threshold. The threshold may indicate, for example, the maximum number of times that CSI is allowed to be reported outside the active time associated with the primary DRX group. For example, the UE may maintain a counter indicating the number of secondary DRX group CSI transmissions outside the active time associated with the primary DRX group. Next, the UE may determine that the flag is enabled, as described above. The UE may then determine whether the counter has reached the threshold (e.g., whether the counter indicates that the maximum number of secondary DRX group CSI transmissions outside the active time of the primary DRX group has been reached). In this example, if the counter has not reached the threshold, the UE may determine the CSI associated with the secondary DRX group and send the CSI in the uplink communication associated with the primary DRX group. Conversely, if the counter has reached the threshold, the UE may skip the measurement opportunity associated with determining the CSI, or avoid sending the CSI in the uplink communication associated with the primary DRX group. In such a case, the UE may also disable the flag (e.g., without an indication from the base station). In some aspects, timers and / or thresholds may be used to limit the number of secondary DRX group CSI transmissions outside of the active time associated with the primary DRX group, thereby saving UE resources.

[0072] In some aspects, when the UE sends CSI associated with the secondary DRX group in uplink communications associated with the primary DRX group, the UE may multiplex the CSI with UCI in the uplink communications. For example, the UE may multiplex the CSI associated with the secondary DRX group with hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback, with CSI associated with the primary DRX group, or with one or more other types of UCI. Additional details regarding multiplexing the CSI associated with the secondary DRX group with UCI are provided below.

[0073] Figure 3B is a schematic diagram showing an example associated with sending CSI associated with a secondary DRX group outside of an active time associated with a primary DRX group. Figure 3B In the example of FIG. 1 , the UE may determine that an uplink communication opportunity (e.g., a PUCCH opportunity) associated with reporting CSI determined based at least in part on the measurement result at the first measurement opportunity is within an active time associated with the primary DRX group. Here, the UE may skip determining whether the flag is enabled or disabled (e.g., because in this case, CSI will be provided during the active time associated with the primary DRX group), may perform a first measurement, and determine a first CSI associated with the secondary DRX group, and provide the first CSI in an uplink communication associated with the primary DRX group, as in FIG. Figure 3B As indicated in .

[0074] At the second measurement occasion associated with the secondary DRX group (at Figure 3B In the example, the UE determines that the flag is enabled. As further shown, the UE may perform a second measurement, and determine a second CSI associated with the secondary DRX group, and provide the second CSI in the uplink communication associated with the primary DRX group. Here, the wake-up is performed at a PUCCH timing associated with sending the second CSI in the uplink communication associated with the primary DRX group.

[0075] At the third measurement occasion associated with the secondary DRX group (at Figure 3B), the UE may determine that the third measurement occasion is outside of the active time associated with the primary DRX group. Thus, the UE may determine whether the flag is enabled or disabled (e.g., because in this case, CSI will be provided outside of the active time associated with the primary DRX group). In this example, the UE determines that the flag is enabled. As further shown, the UE may perform a third measurement, and determine a third CSI associated with the secondary DRX group, and provide the third CSI in an uplink communication associated with the primary DRX group. Here, the wake-up is performed at a PUCCH occasion associated with sending the third CSI in the uplink communication associated with the primary DRX group.

[0076] At the fourth measurement occasion associated with the secondary DRX group (at Figure 3B ), the UE may determine that the fourth measurement occasion is outside the active time associated with the primary DRX group. Thus, the UE may determine whether the flag is enabled or disabled (e.g., because in this case, CSI will be provided outside the active time associated with the primary DRX group). In this example, the UE determines that the flag is enabled. Assume that for the purpose of the fourth measurement occasion, at the end of the active time associated with the primary DRX group, the UE starts a timer associated with the maximum length of time after the active time during which CSI is allowed to be reported in the primary DRX group. Here, the UE may determine whether the timer has expired. In this example, as Figure 3B As shown in , the UE determines that the timer has expired and skips the fourth measurement opportunity (eg, the UE avoids performing measurements associated with determining the fourth CSI). The UE may also disable a flag based at least in part on the expiration of the timer.

[0077] As indicated above, Figure 3A and Figure 3B is provided as an example. Other examples may be related to Figure 3A and Figure 3B The examples described are different.

[0078] Figure 4 is a schematic diagram showing an example associated with cross-DRX group CSI reporting according to the present disclosure. Figure 4 In an associated example, a UE (e.g., UE 120) is configured to use a primary DRX group associated with a primary DRX configuration (e.g., one or more component carriers in FR1) and a secondary DRX group associated with a secondary DRX configuration (e.g., one or more component carriers in FR2). Further, the primary DRX group and the secondary DRX group are associated with a single PUCCH configuration (e.g., a PUCCH configuration indicating resources in the primary DRX group to be used for providing uplink control information).

[0079] like Figure 4 As shown by reference numeral 402, the UE may determine that CSI associated with the secondary DRX group is to be multiplexed with UCI outside of the active time associated with the primary DRX group. In some aspects, the UE may be configured such that the UE is required to multiplex the CSI with UCI outside of the active time associated with the primary DRX group (e.g., rather than being determined by the UE implementation).

[0080] As indicated by reference numeral 404, the UE may send uplink communications in a PUCCH associated with the primary DRX group based at least in part on determining that the CSI will be multiplexed with UCI outside of active times associated with the primary DRX group. Here, the uplink communications include at least CSI associated with the secondary DRX group. In some aspects, the uplink communications may be sent during active times associated with the secondary DRX group. Thus, in some aspects, if there are other overlapping UCI outside of the active times associated with the primary DRX group and during the active times associated with the secondary DRX group, the CSI associated with the secondary DRX group may be reported (regardless of the flag associated with providing the secondary DRX group CSI outside of the active times associated with the primary DRX group).

[0081] In some aspects, the CSI associated with the secondary DRX group is multiplexed with UCI in uplink communications. In some aspects, the UCI multiplexed with the CSI associated with the secondary DRX group may include HARQ-ACK feedback.

[0082] Additionally or alternatively, the UCI multiplexed with the CSI associated with the secondary DRX group may include CSI associated with the primary DRX group. In such a case, the CSI associated with the primary DRX group may be CSI determined based at least in part on the latest measurement results during the active time associated with the primary DRX group.

[0083] In some aspects, the UE may selectively multiplex CSI associated with the secondary DRX group and CSI associated with the primary DRX group in uplink communications. For example, since the UE does not measure CSI on the primary DRX group outside the active time associated with the primary DRX group, the UE may be allowed to omit the primary DRX group CSI from uplink communications outside the active time associated with the primary DRX group. However, there may be a potential misalignment of the DRX timer between the UE and the base station. For example, the base station may believe that the primary DRX group is to be in the active time, and therefore may expect the primary DRX group CSI from the UE. However, the UE may actually be outside the active time associated with the primary DRX group, and therefore may not provide the primary DRX group CSI in the uplink communication. In such a case, due to the DRX timer misalignment, the base station may not be able to decode the uplink communication (e.g., because the base station expects the primary DRX group CSI, but the UE does not provide the primary DRX group CSI). To address this issue, the UE may be configured or instructed in some aspects to always include the primary DRX group CSI in the uplink communication (e.g., CSI determined at least in part based on the latest measurement results during the active time associated with the primary DRX group). Here, the primary DRX group CSI is multiplexed with the secondary DRX group CSI in the uplink communication, and the base station can successfully decode the uplink communication even in the case of DRX timer misalignment. Alternatively, to address the DRX timer misalignment issue, the UE may be configured or instructed in some aspects (e.g., by the base station) to omit the primary DRX group CSI from the uplink communication, and only report the secondary DRX group CSI. In this case, the base station can perform blind decoding under two assumptions: (1) the primary DRX group CSI is multiplexed with the secondary DRX group CSI in the uplink communication, and (2) the primary DRX group CSI is not multiplexed with the secondary DRX group CSI in the uplink communication. Therefore, even when the primary DRX group CSI is not multiplexed with the secondary DRX group CSI, the base station can successfully decode the uplink communication.

[0084] In particular, HARQ-ACK feedback and primary DRX group CSI are provided as examples of UCI, and in some aspects, the UCI multiplexed with the CSI associated with the secondary DRX group may include one or more other types of UCI.

[0085] As indicated above, Figure 4 is provided as an example. Other examples may be related to Figure 4 The examples described are different.

[0086] Figure 55 is a diagram illustrating an example process 500 performed, for example, by a UE according to the present disclosure. Example process 500 is an example of a UE (eg, UE 120, etc.) performing operations associated with cross-DRX group CSI reporting.

[0087] like Figure 5 As shown in , in some aspects, process 500 may include determining whether a flag is enabled or disabled, the flag indicating whether CSI associated with the secondary DRX group is allowed to be transmitted outside of the active time associated with the primary DRX group (block 510). For example, the UE (e.g., using the receive processor 258, the transmit processor 264, the controller / processor 280, the memory 282, etc.) may determine whether a flag is enabled or disabled, the flag indicating whether CSI associated with the secondary DRX group is allowed to be transmitted outside of the active time associated with the primary DRX group, as described above.

[0088] like Figure 5 As further shown in FIG. 5 , in some aspects, process 500 may include selectively transmitting CSI associated with the secondary DRX group in uplink communications associated with the primary DRX group based at least in part on whether the flag is enabled or disabled (block 520). For example, the UE (e.g., using the receive processor 258, the transmit processor 264, the controller / processor 280, the memory 282, etc.) may selectively transmit CSI associated with the secondary DRX group in uplink communications associated with the primary DRX group based at least in part on whether the flag is enabled or disabled, as described above.

[0089] Process 500 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in combination with one or more other processes described elsewhere herein.

[0090] In a first aspect, uplink communications include a PUCCH, and a primary DRX group and a secondary DRX group are associated with a single PUCCH configuration.

[0091] In a second aspect, alone or in combination with the first aspect, configuration of the marking is at least one of: on a per-UE basis, or on a per-DRX group basis.

[0092] In a third aspect, either alone or in combination with one or more of the first and second aspects, configuration of a flag or an indication associated with enabling or disabling a flag is received via at least one of: radio resource control signaling, a medium access control control element, or downlink control information.

[0093] In a fourth aspect, alone or in combination with one or more of the first to third aspects, the marking is configured for the UE based at least in part on UE capability information provided by the UE.

[0094] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, the marking is configured for the UE based at least in part on a UE request sent by the UE.

[0095] In a sixth aspect, alone or in combination with one or more aspects of the first to fifth aspects, when the flag is enabled, selectively sending CSI associated with a secondary DRX group in uplink communications associated with a primary DRX group includes: sending CSI in uplink communications based at least in part on determining that the secondary DRX group is in active time, the CSI being sent during the active time associated with the secondary DRX group.

[0096] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, the wake-up is performed at a PUCCH opportunity associated with sending CSI in uplink communication.

[0097] In the eighth aspect, alone or in combination with one or more aspects from the first to the seventh aspects, when the flag is disabled, selectively sending CSI associated with the secondary DRX group in the uplink communication associated with the primary DRX group includes at least one of the following: skipping a measurement opportunity associated with determining the CSI, or avoiding sending CSI in the uplink communication.

[0098] In a ninth aspect, either alone or in combination with one or more of aspects 1 to 8, CSI is selectively sent in uplink communications based further at least in part on a timer indicating a maximum length of time allowed for reporting CSI in uplink communications after an activity time associated with a primary DRX group.

[0099] In a tenth aspect, either alone or in combination with one or more of aspects one to nine, CSI is selectively sent in uplink communications based at least in part on a threshold indicating a maximum number of times CSI is allowed to be reported outside of active time associated with a primary DRX group.
