Field of the Disclosure

[0003] Broadly, aspects of the present disclosure relate to wireless communication and to techniques and apparatus for configured grant and / or semi - persistent scheduling for a dormant secondary cell group. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ a multiple access technology that is capable of supporting communication with multiple user equipments (UEs) by sharing available system resources (e.g., bandwidth, transmit power). 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 / Advanced LTE is an enhanced collection of the Universal Mobile Telecommunications System (UMTS) mobile standards released by the Third Generation Partnership Project (3GPP).

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

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

[0038] Aspects of the present disclosure are described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be embodied in different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. As will be recognized by those of skill in the art in light of the teachings herein, the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the present disclosure. For example, any number of the aspects set forth herein may be utilized to implement a device or practice a method. Additionally, the scope of the present disclosure is intended to cover such devices and methods practiced using other structures, functions, or combinations of structures and functions in addition to or different from the aspects of the present 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 a claim.

[0039] Several aspects of a telecommunications system will now be presented with reference to various devices and techniques. These devices and techniques will be described in detail hereinafter and will be illustrated in the drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0040] It should be noted that while terms generally associated with 5G or NR radio access technology (RAT) may be used herein to describe aspects, aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RAT (e.g., 6G).

[0041] Figure 1 is a schematic diagram showing an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, etc. The wireless network 100 may include a plurality of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) 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, Node B, gNB, 5G Node B (NB), access point, or transmit receive point (TRP). Each BS may provide communication coverage for a particular geographic area. In 3GPP, depending on the context in which the term is used, the term "cell" may refer to the coverage area of a BS and / or the BS subsystem serving that coverage area.

[0042] The BS can provide communication coverage for macro cells, pico cells, femto cells, and / or another type of cell. A macro cell can cover a relatively large geographical area (e.g., with a radius of several kilometers) and can allow unrestricted access by UEs with service subscriptions. A pico cell can cover a relatively small geographical area and can allow unrestricted access by UEs with service subscriptions. A femto cell can cover a relatively small geographical area (e.g., a home) and can allow restricted access by UEs associated with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG)). The BS for a macro cell can be referred to as a macro BS. The BS for a pico cell can be referred to as a pico BS. The BS for a femto cell can be referred to as a femto BS or a home BS. In Figure 1 the example shown in, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. The BS can support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" can be used interchangeably herein.

[0043] In some aspects, a cell may not necessarily be stationary, and the geographical area of a cell can move according to the position of a mobile BS. In some aspects, the BSs can be interconnected with each other and / or interconnected to one or more other BSs or network nodes (not shown) in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0044] The wireless network 100 can also include relay stations. A relay station is an entity that receives a transmission of data from an upstream station (e.g., a BS or a UE) and sends a transmission of data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. In Figure 1 the example shown in, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, a relay base station, or a repeater.

[0045] The wireless network 100 can be a heterogeneous network including different types of BSs (such as macro BSs, pico BSs, femto BSs, and / or relay BSs). These different types of BSs can have different transmission power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS can have a high transmission power level (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmission power levels (e.g., 0.1 to 2 watts).

[0046] The network controller 130 can be coupled to a set of BSs and provide coordination and control for these BSs. The network controller 130 can communicate with the BSs via a backhaul. The BSs can also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0047] UEs 120 (e.g., 120a, 120b, 120c) can be distributed throughout the wireless network 100, and each UE can be stationary or mobile. UEs can also be referred to as access terminals, terminals, mobile stations, user devices, stations, etc. A UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, a superbook, 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), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0048] Some UEs can be considered as Machine Type Communication (MTC) or evolved or enhanced Machine Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which can communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node can provide a connection to or from a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs can be considered as Internet of Things (IoT) devices, and / or can be implemented as NarrowBand IoT (NB-IoT) devices. Some UEs can be considered as Customer Premises Equipment (CPE). UE 120 can be included inside a housing that houses components of UE 120, e.g., a processor component and / or a memory component. In some aspects, the processor component and the memory component can be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., a memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0049] Generally, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. The RAT can also be referred to as a radio technology and / or an air interface. The frequency can also be referred to as a carrier and / or a frequency channel. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network can be deployed.

[0050] In some aspects, 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 the base station 110 as a medium to communicate with each other). For example, UE 120 can use peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which can include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol), and / or a mesh network to communicate. In such a case, UE 120 can perform scheduling operations, resource selection operations, and / or other operations performed by the base station 110 described elsewhere herein.

[0051] Devices of the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 can communicate using an operating band having a first frequency range (FR1) that can span from 410 MHz to 7.125 GHz, and / or can communicate using an operating band having a second frequency range (FR2) that spans from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the "sub-6 GHz" band. Similarly, FR2 is generally referred to as the "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) defined as the "millimeter wave" band by the International Telecommunication Union (ITU). Thus, unless otherwise explicitly stated, it should be understood that the term "sub-6 GHz", etc., if used herein, can broadly represent frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise explicitly stated, it should be understood that the term "millimeter wave", etc., if used herein, can broadly represent frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). Frequencies included in FR1 and FR2 that can be modified are considered, and the techniques described herein apply to those modified frequency ranges.

[0052] As noted above, Figure 1 is provided as an example. Other examples may be different from those Figure 1 described.

[0053] Figure 2 is a schematic diagram of an example 200 of a base station 110 communicating with a UE 120 in the wireless network 100 according to the present disclosure. The base station 110 can be equipped with T antennas 234a to 234t, and the UE 120 can be equipped with R antennas 252a to 252r, where, generally speaking, T ≥ 1 and R ≥ 1.

[0054] At base station 110, transmit processor 220 may receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCSs) for each UE based at least in part on channel quality indicators (CQIs) received from the UEs, process (e.g., encode and modulate) the data for each UE based at least in part on the selected MCS(s) for the UE, and provide data symbols for all UEs. 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, upper layer signaling) and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signal (CRS), demodulation reference signal (DMRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). If applicable, transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and / or reference symbols and may provide T output symbol streams to T modulators (MOD) 232a through 232t. Each modulator 232 may process its respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process the output sample stream (e.g., convert to analog, amplify, filter, and upconvert) to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0055] At the UE 120, antennas 252a through 252r may receive downlink signals from the base station 110 and / or other base stations and may provide the received signals to demodulators (DEMOD) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, down-convert, 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 the received symbols from all R demodulators 254a through 254r, perform MIMO detection (if applicable) on the received symbols, and provide the detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for the UE 120 to the data sink 260, and provide the decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or combinations thereof. The channel processor may determine a reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), and / or CQI, etc. In some aspects, one or more components of the UE 120 may be included in a housing 284.

[0056] 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.

[0057] Antennas (e.g., antennas 234a through 234t and / or antennas 252a through 252r) may include one or more antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays, etc., or may be included within one or more antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays and other examples. Antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays may include a collection of coplanar antenna elements or a collection of non-coplanar antenna elements. Antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, collections of antenna elements, and / or antenna arrays may include one or more antenna elements coupled to one or more transmit and / or receive components (such as Figure 2 one or more components) of

[0058] 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 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, CP-OFDM), and transmitted 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 comprises 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 (e.g., as described with reference to FIG. Figures 6 - 16 described).

[0059] At base station 110, uplink signals from UE 120 and other UEs may be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information sent 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. Base station 110 may include a communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include a scheduler 246 to schedule UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110 may be included in a modem of base station 110. In some aspects, 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 (e.g., as described with reference to FIG.

[0074] Although Figure 2 the boxes in are shown as distinct components, the functions described above with reference to the boxes can be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functions described with reference to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 can be performed by or under the control of the controller / processor 280.

[0075] As pointed out above, Figure 2 is provided as an example. Other examples may differ from the example described with respect to Figure 2

[0076] Figure 3 is a schematic diagram illustrating an example 300 of CG communication according to the present disclosure. As shown, the example 300 includes a base station (e.g., base station 110) and a UE (e.g., UE 120).

[0077] As Figure 3 ​As shown by reference numeral 305, the base station 110 may send a CG configuration to the UE 120. For example, the base station 110 may send configuration information identifying the CG (e.g., in a Radio Resource Configuration (RRC) message, in a Downlink Control Information (DCI) message). In some aspects, the configuration information identifying the CG may indicate resource allocation (e.g., in the time domain, frequency domain, spatial domain, code domain) or the periodicity associated with the resource allocation. The CG may identify a resource or a set of resources available for the UE 120 to use for uplink communication (e.g., data, control information). For example, the CG configuration may identify the resource allocation for the PUSCH. In some aspects, the CG configuration may identify a resource pool or multiple resource pools available for the UE 120 to use for uplink transmission.

[0078] In some aspects, the CG configuration may configure contention-free CG communication with resources dedicated for the UE 120 to send uplink communication. In this case, the CG configuration may indicate the resource allocation (e.g., in the time domain, frequency domain, spatial domain, code domain) dedicated for the UE 120 to send uplink communication. In some aspects, the CG configuration may configure the resource allocation for the UE 120 to occur periodically such that the resource allocation corresponds to the transmission opportunities that occur periodically. As Figure 3 As shown by reference numeral 310, when the UE 120 has uplink data to send, the UE 120 sends the uplink data in the CG resources identified by the CG configuration. For example, the UE 120 sends the uplink data in one of the CG uplink opportunities in the CG uplink opportunities identified in the CG configuration using the configured resource allocation.

[0079] A CG configuration with a regular periodic CG uplink timing (with dedicated resource allocation for UE 120) may facilitate UEs with periodic uplink traffic (e.g., with unimportant jitter). The CG configuration may configure the periodicity associated with the resource allocation such that the CG uplink timing is associated with a periodic nominal arrival time at which the traffic to be sent to the base station is expected to arrive at UE 120 (or be ready to be sent by UE 120). However, the actual arrival time at which the traffic arrives at UE 120 (or is ready to be sent by UE 120) may be different from the nominal arrival time, and this difference in time is referred to as jitter. In some aspects, traffic jitter can be handled by configuring multiple CGs around the nominal arrival time. In some aspects, multiple opportunities for UE 120 to send uplink communications can be defined within the CG uplink timing. UE 120 can be configured with multiple CG uplinks to allow UE 120 to repeatedly send CG uplink communications and increase the likelihood of the base station receiving the communications. The NR CG uplink can depend on dynamic grant retransmission. In some aspects, to suppress the number of dynamic grants, the CG can be configured with multiple repeated blind retransmissions via each timing.

[0080] In some cases, a CG configuration with dedicated resources allocated according to the UE may be inefficient. For example, a CG configuration with dedicated UE resources for a large number of UEs may result in excessive consumption of PUSCH resources. In this case, a significant portion of the PUSCH resources may be inefficiently utilized, which reduces the system capacity. For example, when multiple CG configurations for a UE are used for dejittering, only a subset of the CG resources is effectively utilized. In another example, when multiple transmission opportunities are defined within each CG uplink timing, only one opportunity can be effectively utilized. In yet another example, when a blind repetition scheme is used for retransmission, the packet may have been decoded after the first one or more repetitions (early decoding), such that the remaining repetitions are unnecessary. Different from the downlink case, this type of inefficient consumption of system resources cannot be solved by scheduling because the base station does not know the exact time at which the traffic will arrive at the UE.

[0081] In some aspects, a statistical multiplexing scheme can be used to allocate CG uplink resources among multiple UEs. Statistical multiplexing of CG uplink communications from multiple UEs may be useful in cases where there are a large number of UEs arriving at the base station associated with slightly random traffic, where the traffic arrival density for the traffic arriving at the UEs varies over time, etc. For example, for a network deployment with a large number of UEs (such as an industrial wireless sensor network), statistical multiplexing of CG uplink communications from multiple UEs may be useful. In such cases, the uplink traffic associated with at least a group of UEs may be delay-insensitive.

[0082] As Figure 3 shown, a contention-based CG configuration can be configured with a resource pool available for multiple UEs to send uplink communications. The contention-based CG configuration uses statistical multiplexing to share the resource pool among multiple UEs. The resource pool includes multiple resources (e.g., in the time domain, frequency domain, spatial domain, code domain) that can be allocated for uplink transmissions for one or more UEs. For example, the x-axis of the shown resource pool can indicate the transmission time, and the y-axis of the shown resource pool can indicate the resources (e.g., frequency domain, spatial domain, code domain) that can be allocated at each transmission time. In some aspects, the same resource pool can be configured for multiple UEs.

[0083] As Figure 3 further shown by reference numeral 315, for a contention-based CG configuration, when UE 120 has uplink data to send, UE 120 performs an admission control process, and if the admission control process is successful, selects one or more resources from the resource pool. In some aspects, the admission control process can include UE 120 selecting a random number (e.g., between 0 and 1 or some other range), comparing the random number with a threshold, and determining whether the random number meets the threshold. If the random number meets the threshold, the admission is successful, and UE 120 selects resources from the resource pool to send uplink communications.

[0084] In some aspects, base station 110 can control the probability of UE 120 accessing the resource pool by setting and / or adjusting the threshold. For example, base station 110 can dynamically adjust the threshold to allow more or fewer UEs to access the resource pool, thereby preventing resource conflicts. Additionally or alternatively, base station 110 can assign different thresholds for different UEs to use.

[0085] At least partially based on UE 120 determining that the random number meets the threshold, UE 120 can select resources from the resource pool to send uplink communications. UE 120 can use random and / or pseudo-random resource selection to select resources from the resource pool. For example, UE 120 can use a hash function that is at least partially based on the UE identifier, time, and / or resource pool index to select resources from the resource pool.

[0086] As Figure 3 further shown by reference numeral 320, UE 120 sends uplink communications to base station 110 on the CG resources. For example, UE 120 uses the resource allocation identified by the CG to send uplink communications, as PUSCH communications.

[0087] There may be two configured grants of two types. For the first type, RRC signaling can be used for parameter configuration and activation. For the second type, RRC signaling can be used for periodic configuration, the physical downlink control channel (PDCCH) can be used for activation and parameter configuration, and the media access control control element (MAC CE) can be used for confirmation of the activation signal. If UE 120 is configured with a configured grant and UE 120 has no data to send, then UE 120 does not send data.

[0088] In some aspects, data can also be sent from base station 110 to UE 120 using periodic SPS transmissions (opportunities). SPS involves periodic resources that are allocated for the initial transmission of a transport block, and dynamic grants are used to schedule retransmissions. SPS transmissions can be sent to UE 120 on the PDSCH without an accompanying PDCCH, thus saving additional PDCCH detection, processing, and decoding at UE 120. UE 120 can be configured to identify pre-configured physical uplink control channel (PUCCH) resources that will be used for SPS hybrid automatic repeat request (HARQ) feedback. The PUCCH resources can use PUCCH format 0 or 1, which can support up to two bits of feedback.

[0089] As noted above, Figure 3 is provided as an example. Other examples may be different from the example regarding Figure 3 described.

[0090] Figure 4 is a schematic diagram showing an example 400 of dual connectivity according to the present disclosure. Figure 4The example shown is for the Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA)-NR Dual Connectivity (ENDC) mode. In the ENDC mode, a UE (such as UE 120) communicates using the LTE RAT on the MCG, and the UE 120 communicates using the NR RAT on the SCG. However, the aspects described herein can be applied to the ENDC mode (e.g., where the MCG is associated with the LTE RAT and the SCG is associated with the NR RAT), the NR-E-UTRA Dual Connectivity (NEDC) mode (e.g., where the MCG is associated with the NR RAT and the SCG is associated with the LTE RAT), the NR Dual Connectivity (NRDC) mode (e.g., where the MCG is associated with the NR RAT and the SCG is also associated with the NR RAT), or another dual connectivity mode (e.g., where the MCG is associated with a first RAT and the SCG is associated with one of the first RAT or a second RAT). The ENDC mode is sometimes referred to as the NR or 5G Non-Standalone (NSA) mode. Thus, as used herein, the dual connectivity mode can refer to the ENDC mode, the NEDC mode, the NRDC mode, and / or another type of dual connectivity mode.

[0091] As Figure 4 shown, the UE 120 can communicate with both an eNB (e.g., 4G base station 110) and a gNB (e.g., 5G base station 110), and the eNB and the gNB can communicate with a 4G / LTE core network (shown as an Evolved Packet Core (EPC) including a Mobility Management Entity (MME), a Packet Data Network Gateway (PGW), a Serving Gateway (SGW), etc.) (e.g., directly or indirectly). In Figure 4 this figure, the PGW and the SGW are collectively shown as P / SGW. In some aspects, the eNB and the gNB can be co-located at the same base station 110. In some aspects, the eNB and the gNB can be included in different base stations 110 (e.g., may not be co-located).

[0092] As Figure 4As further shown, in some aspects, a wireless network that allows operation in 5G NSA mode may use a MCG for a first RAT (e.g., LTE RAT, 4G RAT) and an SCG for a second RAT (e.g., NR RAT, 5G RAT) to allow such operation. In this case, the UE 120 may communicate with the eNB via the MCG and may communicate with the gNB via the SCG. In some aspects, the MCG may anchor the network connection (e.g., for mobility, coverage, control plane information) between the UE 120 and the 4G / LTE core network, and the SCG may be added as an additional carrier to increase throughput (e.g., for data traffic, user plane information). In some aspects, the gNB and the eNB may not transfer user plane information between each other. In some aspects, the UE 120 operating in dual-connectivity mode may be connected simultaneously to an LTE base station 110 (e.g., eNB) and an NR base station 110 (e.g., gNB) (e.g., in the case of ENDC or NEDC), or may be connected simultaneously to one or more base stations 110 using the same RAT (e.g., in the case of NRDC). In some aspects, the MCG may be associated with a first frequency band (e.g., sub-6 GHz band and / or FR1 band), and the SCG may be associated with a second frequency band (e.g., millimeter wave band and / or FR2 band).

[0093] The UE 120 may communicate via the MCG and the SCG using one or more radio bearers (e.g., data radio bearers (DRBs), signaling radio bearers (SRBs), etc.). For example, the UE 120 may use one or more DRBs to send or receive data via the MCG and / or the SCG. Similarly, the UE 120 may use one or more SRBs to send or receive control information (e.g., RRC information, measurement reports). In some aspects, a radio bearer may be dedicated to a specific cell group (e.g., the radio bearer may be an MCG bearer, an SCG bearer). In some aspects, a radio bearer may be a split radio bearer. The split radio bearer may be split in the uplink and / or in the downlink. For example, a DRB may be split in the downlink (e.g., the UE 120 may receive downlink information for the MCG or the SCG in the DRB), but not split in the uplink (e.g., the uplink may be unsplit from the main path to the MCG or the SCG such that the UE 120 transmits only in the uplink on the main path). In some aspects, a DRB may be split in the uplink into a main path to the MCG or the SCG. The DRB split in the uplink may use the main path to send data until the size of the uplink transmission buffer meets the uplink data split threshold. If the uplink transmission buffer meets the uplink data split threshold, the UE 120 may use the DRB to send data to the MCG or the SCG.

[0094] As noted above, Figure 4 is provided as an example. Other examples may be different from those Figure 4 described with respect to

[0095] Figure 5 is a schematic diagram showing an example 500 of a dual-connectivity deployment according to the present disclosure.

[0096] Figure 5 Shows a first scenario, which is a deployment of NRDC in-band carrier aggregation (CA). The MCG may operate in FR1, and the SCG may operate in FR2. It is expected that the measurements on the primary secondary cell (PSCell) of the SCG are highly correlated with the measurements on the secondary cells (SCells) of the SCG. Therefore, the PSCell measurements may be sufficient.

[0097] Figure 5A second scenario is also shown, which is the deployment of ENDC inter-band CA. The MCG can operate in an LTE band, and the SCG can operate in both FR1 and FR2. For example, the PSCell of the SCG can operate in FR1, and the SCell can operate in FR2. Measurements on the PSCell may be irrelevant to those on the SCell. Therefore, measurements on the PSCell and the SCell may be required. For example, the quasi-correlation or spatial relationship on the PSCell and the SCell may be very different.

[0098] As pointed out above, Figure 5 is provided as an example. Other examples may be different from those Figure 5 described.

[0099] In a dual-connectivity scenario (e.g., ENDC, NRDC), the SCG can be activated and deactivated. When active, it consumes power, signaling resources, and processing resources, and thus the SCG can be deactivated. The SCG can also be deactivated if there is bursty traffic, the UE overheats, or if there is certain types of traffic (e.g., voice). However, when the SCG is deactivated, measurement reports and other preparation signaling may not occur. In addition, when the SCG is activated or deactivated, latency is introduced and resources are also consumed. In some aspects, the SCG can enter an SCG sleep state instead of a deactivated state. In the SCG sleep state, there may be no downlink control, downlink data monitoring, uplink sounding reference signal (SRS), or PUSCH transmission for secondary cells. During the SCG sleep state, some radio resource management (RRM), channel state information (CSI), and beam failure detection measurements may be required, and such measurements are typically reported by the PSCell in the active state. Operations in FR2 may require additional signaling, measurements, and sounding procedures for beam measurements.

[0100] The UE can perform some measurements on the PSCell or SCell in the SCG sleep state, but the MCG is not in a sleep state. The MCG and the SCG may be out of sync, and some measurements may be inaccurate. In addition, sending measurements between the MCG and the SCG may require too many modifications and introduce too much latency. Therefore, the PSCell of the SCG can report some measurements, especially layer 1 (L1) measurements, and there may be a trade-off among power consumption, performance, and latency. When bringing the SCG out of the SCG sleep state, such as when the sleeping bandwidth part (BWP) overlaps with the non-sleeping BWP, the PSCell report can reduce latency and improve performance.

[0101] To send measurement reports via a dormant PSCell, it may be necessary to maintain timing, transmit power, TCI state, and spatial relationships. This may require enabling PUCCH, PDCCH, PDSCH, and PUSCH on the PSCell. However, enabling these physical channels may result in excessive signaling and power consumption of the UE.

[0102] According to various aspects described herein, a UE (e.g., UE 120) may use pre-configured resources, such as a CG for uplink communication between the PSCell and the SN of the SCG during the SCG dormant state and an SPS for downlink communication between the PSCell and the SN of the SCG. For example, the UE may be configured for the CG, the SPS, or both the CG and the SPS. If configured for the CG, the UE may send measurement information and / or SRS to the SN in a CG opportunity on the PUSCH. If only the CG is configured (without the SPS), the CG may not be configured with a downlink or PDCCH. If configured for the SPS, the UE may receive tracking information (e.g., timing advance command, transmit power command, beam update), measurement information, and / or configuration information in an SPS transmission on the PDSCH from the SN. Only the SPS may be configured (without the CG). The PUCCH may be used on the uplink. The CG and / or the SPS may be configured with a specific periodicity. In this way, the UE may reduce control overhead and reduce power consumption.

[0103] In some aspects, if the UE is configured for both the CG and the SPS, the periodicity for each of the CG and the SPS may be configured such that there is a minimum offset between some or all of the CG opportunities and the SPS transmissions. As a result, the CG opportunities and the SPS transmissions may avoid conflicts, provide sufficient resources, and be closer together in time, thereby limiting the active time of the PSCell. The downlink monitoring window may be aligned with each SPS transmission.

[0104] Figure 6 is a schematic diagram showing an example 600 associated with a UE configured with a CG and an SPS for an SCG dormant state according to the present disclosure. As Figure 6 shown, a UE 610 (e.g., UE 120), a master node (MN) 620 (e.g., the base station 110 of the MCG), and an SN 630 (e.g., the base station 110 of the SCG) may communicate with each other. The CG and / or SPS configuration may be used by the UE 610 and the SN 630 for the PSCell. In some aspects, only the PDSCH may be configured on the downlink for the SPS, and only the PUSCH may be configured on the uplink for the CG.

[0105] As shown by reference numeral 640, the MN 620 may determine that the SCG is going to enter the SCG dormant state. This may be due to problems at the UE, the type of service and / or channel conditions, and other reasons. As shown by reference numeral 645, the MN 620 may send an indication to the SN 630 that the SCG is going to enter the SCG dormant state. As shown by reference numeral 650, the SN 630 may confirm the indication. Accordingly, as shown by reference numeral 655, the SN 630 may operate as if the SCG were in the SCG dormant state.

[0106] As shown by reference numeral 660, if the MN 620 receives the confirmation, the MN 620 may send the same indication to the UE 610. The indication may be accompanied by an indication of the CG and / or SPS configuration, depending on whether the UE is to be configured for CG, SPS, or both. As shown by reference numeral 665, the UE 610 may operate as if the SCG were in the SCG dormant state. As shown by reference numeral 670, the SN 630 may also receive an indication of the CG and / or SPS configuration.

[0107] If configured for CG, the UE 610 may use CG opportunities during a certain period to communicate with the SN 630. If configured for SPS, the SN 630 may use SPS transmissions during a certain period to communicate with the UE 610. In example 600, the UE 610 and the SN 630 may be configured to use both CG and SPS.

[0108] As shown by reference numeral 675, the UE 610 may send measurement information (e.g., CSI report, L1 measurement) and / or SRS to the SN 630 on the PUSCH in a first CG opportunity. HARQ feedback for downlink messages may be sent to the SN 630 using the PUSCH on the CG opportunity. The UE 610 may derive uplink tracking information (such as transmit power) from PUSCH / SRS communication. As shown by reference numeral 680, the UE 610 may receive tracking information (e.g., timing advance command, transmit power command, beam update or spatial relation as a TCI state), measurement information, and / or measurement configuration information from the SN 630 in a first SPS transmission on the PDSCH. The UE 610 may also receive L1 measurement triggers, configurations, resource sets, and / or reference signals on the PDSCH. As shown by reference numeral 685, the UE 610 may send measurement information and / or SRS on the PUSCH in a second CG opportunity. As shown by reference numeral 690, the UE 610 may receive tracking information, measurement information, and / or configuration information in a second SPS transmission on the PDSCH.

[0109] As pointed out above, Figure 6is provided as an example. Other examples may be different from those Figure 6 described.

[0110] Figure 7 is a schematic diagram showing examples 700 and 702 of CG timing according to the present disclosure.

[0111] If a data packet (e.g., UL DATA 0) sent by the UE is not received by the SN, the UE may retain the data in its buffer for a time specified by the CG retransmission timer. If the timer has not expired, the SN may send a dynamic uplink grant in the SPS timing on the PDSCH (or on the PDCCH) to point to newly allocated resources (other than the CG timing) or another CG timing. Example 70C shows an example of using newly allocated resources (for retransmission of UL DATA 0). Example 702 is an example of using another CG timing (CG timing 3). In some aspects, the dynamic grant may be sent in a MAC CE, DCI, or RRC message.

[0112] As pointed out above, Figure 7 examples are provided. Other examples may be different from those Figure 7 described.

[0113] Figure 8 is a schematic diagram showing example 800 of CG timing according to the present disclosure.

[0114] Example 800 shows an example of message repetition for the CG timing, where the UE may send the message K times for each CG timing to increase the probability of repetition by the SN. If the data packet (e.g., UL DATA 0) is not received in the first repetition of the CG timing, the data packet (retransmission of UL DATA 0) may be received in another (2nd to Kth) repetition of the same CG timing.

[0115] As pointed out above, Figure 8 is provided as an example. Other examples may be different from those Figure 8 described.

[0116] Figure 9 is a schematic diagram showing examples 900 and 902 of SPS transmission according to the present disclosure.

[0117] If the data in the SPS transmission (e.g., DL DATA 0) is not decoded by the UE, the UE may send a NACK to the SN on the PUSCH (if CG is configured). The SN may use dynamic grant to reschedule the retransmission. The SN may send the dynamic grant on DCI (DCI on the PDSCH, which may be equivalent to a MAC CE) in another SPS transmission. The DCI or MAC CE may point to new resources (other than the SPS transmission) for the (DL DATA 0) retransmission, such as shown in Example 900. The DCI or MAC CE may also point to another SPS transmission (e.g., SPS transmission 3), such as shown in Example 902.

[0118] As noted above, Figure 9 some examples are provided. Other examples may be different from those Figure 9 described.

[0119] Figure 10 is a schematic diagram showing Example 1000 of an SPS transmission according to the present disclosure.

[0120] To save signaling overhead, the retransmission may occur automatically in the SPS transmission in the next SPS occasion or in resources other than the SPS occasion. For example, the UE may be preconfigured to expect the retransmission in the next SPS transmission (e.g., SPS transmission 2) or a certain number of SPS transmissions from the original transmission.

[0121] As noted above, Figure 10 is provided as an example. Other examples may be different from those Figure 10 described.

[0122] The PSCell may operate under multiple nodes. In PSCell mode 0, the PDSCH (SPS) is used for the downlink, the PUCCH / PUSCH is used for the uplink, and the MAC CE is used for signaling. In PSCell mode 1, the PDCCH / PDSCH is used for the downlink, the PUSCH (CG) is used for the uplink, and the MAC CE is used for signaling. In PSCell mode 2, the PDSCH (SPS) is used for the downlink, the PUSCH (CG) is used for the uplink, and the MAC CE is used for signaling.

[0123] If the PDCCH is not activated on the PSCell, parameter changes can be signaled via a MAC CE. If the PDSCH and / or PUSCH are enabled, MAC layer signaling can be used. MAC layer signaling can be used to transmit the transmission power control (TPC) for the SRS or the PUCCH that is typically indicated by DCI. To update the timing parameters, a MAC CE can be used to signal the timing advance on the PUCCH, SRS, or PUSCH. For the transmit power parameter, a MAC CE (instead of DCI) for the PUCCH, SRS, or PUSCH can be used to signal the TPC. For the downlink TCI state, a MAC CE can be used for the PDCCH or PDSCH. For the spatial relation, a MAC CE can be used for the PUCCH or PUSCH.
