Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Patent Cooperation Treaty (PCT) application numbered PCT / CN2019 / 112422, entitled “SECONDARY CELL DORMANCYUSING DORMANCY PROFILE,” filed on October 22, 2019, which is hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for secondary cell dormancy using a dormancy profile. Background Art

[0004] Wireless communication systems are widely deployed to provide various 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).

[0005] A wireless communication network may include multiple base stations (BS) that can support communications for multiple user equipment (UE). User equipment (UE) may communicate with a base station (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.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at city, country, region, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard released by the Third Generation Partnership Project (3GPP). NR is designed to better integrate with other open standards 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), and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to better support mobile broadband Internet access. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0007] In some aspects, a method of wireless communication performed by a user equipment (UE) may include: receiving bandwidth portion configuration information for configuring a sleep profile for a first bandwidth portion among multiple bandwidth portions; transmitting multiple types of signaling on a second bandwidth portion; and transmitting a subset of the multiple types of signaling on the first bandwidth portion, such that at least one type of signaling among the multiple types of signaling is suppressed according to the sleep profile.

[0008] In some aspects, a UE for wireless communication may include a memory and one or more processors operatively coupled to the memory. The memory and the one or more processors may be configured to: receive bandwidth portion configuration information for configuring a sleep profile for a first bandwidth portion of a plurality of bandwidth portions; transmit multiple types of signaling on a second bandwidth portion; and transmit a subset of the multiple types of signaling on the first bandwidth portion such that at least one type of signaling of the multiple types of signaling is suppressed according to the sleep profile.

[0009] 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 perform the following operations: receiving bandwidth portion configuration information for configuring a sleep profile for a first bandwidth portion of a plurality of bandwidth portions; transmitting multiple types of signaling on a second bandwidth portion; and transmitting a subset of the multiple types of signaling on the first bandwidth portion, such that at least one type of signaling of the multiple types of signaling is suppressed according to the sleep profile.

[0010] In some aspects, an apparatus for wireless communication may include: a unit for receiving bandwidth portion configuration information for configuring a sleep profile for a first bandwidth portion among multiple bandwidth portions; a unit for transmitting multiple types of signaling on a second bandwidth portion; and a unit for transmitting a subset of the multiple types of signaling on the first bandwidth portion, such that at least one type of signaling among the multiple types of signaling is suppressed according to the sleep profile.

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

[0024] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements") and illustrated in the accompanying drawings. These elements may 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 although various aspects may be described herein using terminology typically associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applicable to communication systems based on other generations, such as 5G and beyond, including NR technology.

[0026] Figure 1 1 is a schematic diagram showing a wireless network 100 in which various aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include a plurality of BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, 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 1In the example shown in , 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", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0028] In some aspects, the cells may not necessarily be 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 with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections, virtual networks, etc.) using any appropriate 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 is capable of relaying transmissions for other UEs. Figure 1 In the example shown in FIG. 1 , a relay station 110 d may communicate with a macro BS 110 a and a UE 120 d to facilitate communication between the BS 110 a and the UE 120 d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0030] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, 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] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these 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 or wired backhaul.

[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 apparatus, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), an entertainment device (e.g., a music or video device, or a satellite wireless unit, etc.), a vehicle assembly 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 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, location tags, etc., which may 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 a network, for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (e.g., processor components, memory components, etc.).

[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, 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 for communicating with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol, etc.), mesh network, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0036] As indicated above, Figure 1 is provided as an example. Other examples may differ from those described above. Figure 1 Examples described.

[0037] Figure 2 1 and UE 120 (base station 110 may be Figure 1 UE 120 may be one of the base stations in Figure 1 1. Block diagram of a design 200 of a UE in a UE. 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.

[0038] 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), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), 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)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, synchronization signals may be generated using position coding to convey additional information.

[0039] At UE 120, antennas 252a to 252r may receive downlink signals from 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, etc.) to obtain received symbols. A 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. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included within a housing.

[0040] 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, CQI, etc.). 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, etc.), and transmitted to the base station 110. 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 transmitted by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0041] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components in the base station 110 may perform one or more techniques associated with secondary cell dormancy using a dormancy profile, 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 in may perform or direct e.g. Figure 8 The operations of process 800 and / or other processes as described herein. Memories 242 and 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 for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120, may perform or direct, for example, Figure 8 The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0042] In some aspects, UE 120 may include: means for receiving bandwidth portion configuration information for configuring a sleep profile for a first bandwidth portion of the plurality of bandwidth portions; means for transmitting a plurality of types of signaling on a second bandwidth portion; means for transmitting a subset of the plurality of types of signaling on the first bandwidth portion such that at least one type of signaling of the plurality of types of signaling is suppressed according to the sleep profile; 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.

[0043] As mentioned above, Figure 2 is provided as an example. Other examples may differ from those described above. Figure 2 Examples described.

[0044] Figure 3A An example frame structure 300 for frequency division duplex (FDD) in a telecommunication system (e.g., NR) is shown. The transmission timeline for each of the downlink and uplink may be divided into units of radio frames (sometimes referred to as frames). Each radio frame may have a predetermined duration (e.g., 10 milliseconds (ms)) and may be divided into a set of Z (Z ≥ 1) subframes (e.g., with indices from 0 to Z-1). Each subframe may have a predetermined duration (e.g., 1 ms) and may include a set of time slots (e.g., in Figure 3A Each subframe 2 is shown inm time slots, where m is the numerology used for transmission, such as 0, 1, 2, 3, 4, etc.). Each time slot may include a set of L symbol periods. For example, each time slot may include fourteen symbol periods (e.g., Figure 3A ), seven symbol periods, or another number of symbol periods. In the case where a subframe includes two slots (e.g., when m=1), the subframe may include 2L symbol periods, where the 2L symbol periods in each subframe may be assigned indices from 0 to 2L-1. In some aspects, the scheduling unit for FDD may be frame-based, subframe-based, slot-based, symbol-based, etc.

[0045] Although some techniques are described herein in conjunction with frames, subframes, time slots, etc., these techniques may also be applied to other types of wireless communication structures, which in 5G NR may be referred to using terms other than "frames," "subframes," "time slots," etc. In some aspects, a wireless communication structure may refer to a periodic, time-limited communication unit defined by a wireless communication standard and / or protocol. Additionally or alternatively, a wireless communication structure may be used in conjunction with Figure 3A The configurations of different wireless communication structures are shown in FIG.

[0046] In some telecommunications (e.g., NR), a base station may send synchronization signals. For example, a base station may send a primary synchronization signal (PSS), a secondary synchronization signal (SSS), etc. on the downlink for each cell supported by the base station. The PSS and SSS may be used by the UE for cell search and acquisition. For example, the PSS may be used by the UE to determine symbol timing, and the SSS may be used by the UE to determine a physical cell identifier and frame timing associated with the base station. The base station may also send a physical broadcast channel (PBCH). The PBCH may carry certain system information, such as system information that supports initial access by the UE.

[0047] In some aspects, a base station may send a PSS, SSS, and / or PBCH according to a synchronization communication level (e.g., a synchronization signal (SS) level) including multiple synchronization communications (e.g., SS blocks), as described below in conjunction with Figure 3B Descriptive.

[0048] Figure 3B is a block diagram conceptually illustrating an example SS hierarchy, which is an example of a synchronous communication hierarchy. Figure 3BAs shown in , the SS level may include an SS burst set, which may include multiple SS bursts (identified as SS burst 0 to SS burst B-1, where B is the maximum number of repetitions of the SS burst that can be sent by the base station). As further shown, each SS burst may include one or more SS blocks (identified as SS block 0 to SS block (b max_SS-1 ), where b max_SS-1 is the maximum number of SS blocks that can be carried by an SS burst). In some aspects, different SS blocks may be beamformed differently. A set of SS bursts may be sent by a wireless node periodically, such as every X milliseconds, e.g. Figure 3B In some aspects, the SS burst set may have a fixed or dynamic length. Figure 3B Shown in Y milliseconds.

[0049] Figure 3B The SS burst sets shown in are examples of synchronous communication sets, and other synchronous communication sets may be used in conjunction with the techniques described herein. Figure 3B The SS blocks shown in are examples of synchronous communications, and other synchronous communications may be used in conjunction with the techniques described herein.

[0050] In some aspects, an SS block includes resources that carry PSS, SSS, PBCH, and / or other synchronization signals (e.g., a third synchronization signal (TSS)) and / or synchronization channels. In some aspects, multiple SS blocks are included in an SS burst, and the PSS, SSS, and / or PBCH may be the same across each SS block in the SS burst. In some aspects, a single SS block may be included in an SS burst. In some aspects, an SS block may be at least four symbol periods in length, with each symbol carrying one or more of PSS (e.g., occupying one symbol), SSS (e.g., occupying one symbol), and / or PBCH (e.g., occupying two symbols).

[0051] In some aspects, such as Figure 3B As shown in , the symbols of the SS blocks are continuous. In some aspects, the symbols of the SS blocks are discontinuous. Similarly, in some aspects, one or more SS blocks in an SS burst may be sent in continuous radio resources (e.g., continuous symbol periods) during one or more time slots. Additionally or alternatively, one or more SS blocks in an SS burst may be sent in discontinuous radio resources.

[0052] In some aspects, an SS burst may have a burst period, whereby an SS block in the SS burst is sent by the base station according to the burst period. In other words, the SS block may be repeated during each SS burst. In some aspects, an SS burst set may have a burst set period, whereby an SS burst in the SS burst set is sent by the base station according to a fixed burst set period. In other words, the SS burst may be repeated during each SS burst set.

[0053] The BS may send system information, such as system information blocks (SIBs), on a physical downlink shared channel (PDSCH) in certain time slots. The base station may send control information / data on a physical downlink control channel (PDCCH) in C symbol periods of a time slot, where B may be configurable for each time slot. The base station may send traffic data and / or other data on the PDSCH in the remaining symbol periods of each time slot.

[0054] As indicated above, Figure 3A and Figure 3B is provided as an example. Other examples may differ from those described above. Figure 3A and Figure 3B Examples described.

[0055] Figure 4 An example slot format 410 with a normal cyclic prefix is ​​shown. The available time-frequency resources may be divided into resource blocks. Each resource block may cover a set of subcarriers (e.g., 12 subcarriers) in a slot and may include multiple resource elements. Each resource element may cover a subcarrier in a symbol period (e.g., in units of time) and may be used to send a modulation symbol, which may be real or complex valued.

[0056] The interlaced structure may be used for each of the downlink and uplink for FDD in certain telecommunication systems (e.g., NR). For example, Q interlaces with indices from 0 to Q-1 may be defined, where Q may be equal to 4, 6, 8, 10, or some other value. Each interlace may include time slots spaced apart by Q frames. In particular, an interlace q may include time slots q, q+Q, q+2Q, etc., where q∈{0,…,Q–1}.

[0057] A UE may be located within the coverage of multiple BSs. One of these BSs may be selected to serve the UE. The serving BS may be selected based at least in part on various criteria such as received signal strength, received signal quality, path loss, etc. The received signal quality may be quantified by a signal to noise and interference ratio (SNIR), or a reference signal received quality (RSRQ), or some other metric. The UE may operate in a significant interference scenario, in which the UE may observe high interference from one or more interfering BSs.

[0058] Although aspects of the examples described herein may be associated with NR or 5G technology, aspects of the present disclosure may be applicable with other wireless communication systems. New Radio (NR) may refer to a radio configured to operate according to a new air interface (e.g., in addition to an air interface based on Orthogonal Frequency Division Multiple Access (OFDMA)) or a fixed transport layer (e.g., in addition to Internet Protocol (IP)). In various aspects, NR may utilize OFDM with CP (referred to herein as cyclic prefix OFDM or CP-OFDM) and / or SC-FDM on the uplink, may utilize CP-OFDM on the downlink, and include support for half-duplex operation using time division duplex (TDD). In various aspects, NR may, for example, utilize OFDM with CP (referred to herein as CP-OFDM) and / or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) on the uplink, may utilize CP-OFDM on the downlink, and include support for half-duplex operation using TDD. NR may include enhanced mobile broadband (eMBB) services targeting wide bandwidth (e.g., 80 megahertz (MHz) and beyond), millimeter wave (mmW) targeting high carrier frequencies (e.g., 60 gigahertz (GHz)), massive MTC (mMTC) targeting non-backward compatible MTC technologies, and / or mission critical services targeting ultra-reliable low latency communications (URLLC) services.

[0059] In some aspects, a single component carrier bandwidth of 100 MHz may be supported. NR resource blocks may span 12 subcarriers with a subcarrier bandwidth of 60 or 120 kilohertz (kHz) in a duration of 0.1 milliseconds (ms). Each radio frame may include 40 time slots and may have a length of 10 ms. Thus, each time slot may have a length of 0.25 ms. Each time slot may indicate a link direction (e.g., DL or UL) for data transmission, and the link direction for each time slot may be switched dynamically. Each time slot may include DL / UL data and DL / UL control data.

[0060] Beamforming may be supported and the beam direction may be dynamically configured. MIMO transmission with precoding may also be supported. MIMO configuration in DL may support up to 8 transmit antennas with up to 8 streams and multi-layer DL transmission of up to 2 streams per UE. Multi-layer transmission with up to 2 streams per UE may be supported. Aggregation of multiple cells may be supported with up to 8 serving cells. Alternatively, NR may support different air interfaces other than OFDM-based interfaces. NR networks may include entities such as central units or distributed units.

[0061] As indicated above, Figure 4 is provided as an example. Other examples may differ from those described above. Figure 4 Examples described.

[0062] Figure 5 An example logical architecture of a distributed RAN 500 according to various aspects of the present disclosure is shown. A 5G access node 506 may include an access node controller (ANC) 502. The ANC may be a central unit (CU) of the distributed RAN 500. The backhaul interface to the next generation core network (NG-CN) 504 may terminate at the ANC. The backhaul interface to the neighboring next generation access node (NG-AN) may terminate at the ANC. The ANC may include one or more TRPs 508 (which may also be referred to as BS, NR BS, Node B, 5G NB, AP, gNB or some other terminology). As described above, TRP may be used interchangeably with "cell".

[0063] The TRP 508 may be a distributed unit (DU). The TRP may be connected to one ANC (ANC 502) or more than one ANC (not shown). For example, for RAN sharing, Radio as a Service (RaaS), and service-specific ANC deployments, the TRP may be connected to more than one ANC. The TRP may include one or more antenna ports. The TRP may be configured to serve traffic to the UE individually (e.g., dynamically selected) or jointly (e.g., joint transmission).

[0064] The local architecture of RAN 500 can be used to illustrate fronthaul communications. The architecture can be defined to support fronthaul solutions across different deployment types. For example, the architecture can be based at least in part on transport network capabilities (e.g., bandwidth, latency, and / or jitter).

[0065] The architecture may share features and / or components with LTE. According to various aspects, the next generation AN (NG-AN) 510 may support dual connectivity with NR. The NG-AN may share a common fronthaul for LTE and NR.

[0066] The architecture may enable collaboration between and among TRPs 508. For example, collaboration may be pre-set within and / or across TRPs via ANC 502. According to various aspects, an inter-TRP interface may not be required / existent.

[0067] According to various aspects, dynamic configuration of split logical functions may exist within the architecture of the RAN 500. Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), or Medium Access Control (MAC) protocols may be adaptively placed at the ANC or TRP.

[0068] According to various aspects, a BS may include a central unit (CU) (eg, ANC 502) and / or one or more distributed units (eg, one or more TRPs 508).

[0069] As indicated above, Figure 5 is provided as an example. Other examples may differ from those described above. Figure 5 Examples described.

[0070] Figure 6 An example physical architecture of a distributed RAN 600 according to aspects of the present disclosure is shown. A centralized core network unit (C-CU) 602 may host core network functions. The C-CU may be centrally deployed. C-CU functions may be offloaded (e.g., to Advanced Wireless Services (AWS)) in an attempt to handle peak capacity.

[0071] A centralized RAN unit (C-RU) 604 may host one or more ANC functions. Optionally, the C-RU may host core network functions locally. The C-RU may have a distributed deployment. The C-RU may be closer to the network edge.

[0072] A distributed unit (DU) 606 may host one or more TRPs. The DU may be located at the edge of the network with radio frequency (RF) capabilities.

[0073] As indicated above, Figure 6 is provided as an example. Other examples may differ from those described above. Figure 6 Examples described.

[0074] In some communication systems, the UE and the BS may communicate using one or more bandwidth parts. By dividing the communication bandwidth into bandwidth parts, the BS may support UEs that do not have the ability to monitor the entire communication bandwidth. Additionally, the UE may monitor a subset of the bandwidth parts to achieve reduced power consumption relative to monitoring the entire communication bandwidth. Furthermore, the BS and the UE may configure parameters on a per-bandwidth part basis, which may enable optimization of communications for different use cases.

[0075] Some aspects described herein provide a sleep profile to define a sleep state or sleep behavior for a bandwidth portion associated with a secondary cell. For example, a BS may configure a sleep bandwidth portion for a secondary cell, and on the sleep bandwidth portion, some types of communication functions may be configured, and other types of communication functions may not be configured, thereby achieving power saving. For example, a BS may configure channel state information (CSI) communication, radio resource management (RRM) communication, etc., but may abandon configuration of physical downlink control channel (PDCCH) monitoring. In this case, the UE may perform CSI communication, RRM communication, etc. on the sleep bandwidth portion according to the sleep profile, and may abandon PDCCH monitoring on the sleep bandwidth portion. Further, on another bandwidth portion configured with a non-sleep profile (e.g., for a primary cell), the UE may perform PDCCH monitoring. In this way, the UE reduces power utilization relative to maintaining an active state on each bandwidth portion.

[0076] In some aspects, for each secondary cell group, a one-bit downlink control information (DCI) indication for triggering switching from dormant behavior to non-dormant behavior may be introduced. Thus, which bandwidth part is the dormant bandwidth part may be explicitly configured in the radio resource control (RRC) signaling. And, the network (e.g., BS) and the UE may agree on which bandwidth part the UE is to switch from the dormant bandwidth part to.

[0077] In some aspects, for each secondary cell group, a one-bit DCI indication is introduced to indicate the switch from sleep behavior to non-sleep behavior. Therefore, the one-bit DCI may not indicate which bandwidth part the UE is to switch to. As a result, the sleep bandwidth part may be explicitly indicated in the RRC signaling. And, when an indication is received for converting from sleep behavior to non-sleep behavior, the UE may switch from the sleep bandwidth part to the first active bandwidth part (if configured by RRC) or the last active bandwidth part. In some aspects, based at least in part on using the physical uplink control channel (PUCCH) of the primary and secondary cells for CSI reporting during the suspension of the secondary cell group, the sleep secondary cells may follow the primary and secondary cell discontinuous reception (DRX) for CSI / RRM measurement report triggering.

[0078] Fig. 7A and Figure 7B 7 is a diagram illustrating an example 700 of secondary cell dormancy using a dormancy profile according to various aspects of the present disclosure. Fig. 7A and Figure 7B As shown, example 700 includes BS 110 and UE 120 .

[0079] As in Fig. 7AAs further shown in and by reference number 702, UE 120 may receive sleep profile configuration information and / or non-sleep profile configuration information. The sleep profile may include a configuration parameter set having parameters for sleep behavior. In some aspects, UE 120 may receive information identifying the sleep profile in a bandwidth portion configuration message. For example, during initial bandwidth portion configuration or during bandwidth portion reconfiguration, UE 120 may receive a sleep profile defining a set of parameters for a bandwidth portion such that the bandwidth portion is associated with a sleep state.

[0080] In some aspects, the sleep profile may be related to the secondary cell. For example, the UE 120 may receive information for identifying the sleep profile for the secondary cell associated with a specific bandwidth portion. In some aspects, the UE 120 may only receive the sleep profile for the secondary cell, and the secondary cell may operate according to the sleep state or sleep behavior until reconfigured. In this case, the bandwidth portion may be defined as a sleep bandwidth portion based at least in part on having only a sleep profile. Alternatively, the UE 120 may receive a sleep profile and a non-sleep profile (e.g., a parameter set for the bandwidth portion so that the bandwidth portion is not associated with the sleep state). In this case, the UE 120 may receive signaling (e.g., layer 1 (L1) signaling) for indicating whether to use a sleep profile or a non-sleep profile. In this way, the BS 110 and the UE 120 may enable dynamic switching, which may achieve further optimization of the use of network resources, the consumption of power resources, etc.

[0081] In some aspects, the sleep profile can be a downlink sleep profile configured by radio resource control (RRC). For example, BS 110 can use RRC signaling to send the sleep profile, and can include a specific type of PDCCH configuration parameters. In this case, BS 110 can provide a sleep profile in which PDCCH monitoring is not configured. Additionally or alternatively, BS 110 can provide a sleep profile in which PDCCH monitoring is configured but control resource sets (CORESET) are not configured or search spaces are not configured. In some aspects, the sleep profile can include parameters that are optionally configured. For example, BS 110 can selectively configure physical downlink shared channel (PDSCH) monitoring, RRM communication, beam failure detection, etc. Additionally or alternatively, BS 110 may not configure, for example, semi-persistent scheduling for a bandwidth portion on which the sleep profile is being used.

[0082] In some aspects, the sleep profile can be an uplink sleep profile configured by RRC. For example, BS 110 may provide information for identifying a sleep profile with specific physical uplink control channel (PUCCH) configuration parameters. In this case, BS 110 may configure PUCCH for CSI reporting in a PUCCH secondary cell (PUCCH-S-Cell), and not for PUCCH transmission in other secondary cells in the secondary cell group. Additionally or alternatively, BS 110 may provide a physical uplink shared channel (PUSCH) configuration in the sleep profile. In contrast, BS 110 may give up providing a random access channel (RACH) configuration, a configured permitted transmission configuration, and the like. In some aspects, BS 110 may provide a sounding reference signal (SRS) configuration. For example, BS 110 may give up configuring SRS in a non-PUCCH-S-Cell, but may optionally configure SRS in a PUCCH-S-Cell.

[0083] In some aspects, the UE 120 may receive a dormancy profile related to a secondary cell group. For example, the UE 120 may receive a dormancy profile having a parameter set for secondary cell operation, primary and secondary cell operation, etc. In this case, when the primary and secondary cells in the secondary cell group are communicating with the UE 120 according to the dormancy profile, one or more BSs 110 may operate the secondary cell group according to the dormancy profile. In contrast, when the primary and secondary cells are activated to a non-dormant state, one or more BSs 110 may activate the secondary cells in the secondary cell group. In some aspects, for an uplink dormancy profile for a secondary cell group, the UE 120 may receive parameters indicating that PUCCH communication is configured for CSI reporting or scheduling request transmission, RACH is optionally configured, and / or SRS transmission is optionally configured.

[0084] As shown by reference number 702', in conjunction with the sleep profile and for secondary cell group operation, the UE 120 can maintain timing alignment for the primary and secondary cells in the sleep profile in conjunction with the activation of the non-sleep profile. For example, when the UE 120 switches from the sleep profile to the non-sleep profile, the timing alignment can be maintained to reduce the delay associated with the RACH process. In some aspects, the UE 120 can receive a timing advance command (TAC) MAC CE (e.g., from the MN BS 110) to determine the timing alignment. For example, when the sleep profile is active, the UE 120 can receive a TAC MAC CE to indicate the timing alignment for the primary and secondary cells. In this case, as shown by reference number 703-1, the UE 120 can receive a timing alignment command, which includes a reserved bit, a primary cell group (MCG) / secondary cell group (SCG) identifier (shown as ***) bit, a timing alignment group identifier, and a 12-bit timing advance command. In this case, UE 120 may use the MCG / SCG identifier bit to determine whether the TAC MAC CE applies to the MCG or SCG. In some aspects, BS 110 may configure the primary and secondary cells to have a long-cycle connected discontinuous reception (C-DRX) mode and cause each secondary cell in the secondary cell group to enter a dormant state.

[0085] In some aspects, UE 120 may receive radio resource control (RRC) signaling from MN BS 110. For example, UE 120 may receive RRC signaling for transmitting timing alignment for a primary and secondary cell, a PUCCH secondary cell, and the like of an SCG. In this case, BS 110 may determine the timing alignment based on periodic or semi-persistent channel state information (CSI) reported in the PUCCH configured in the uplink sleep profile of the primary and secondary cell or the PUCCH secondary cell. In some aspects, the RRC signaling may include information indicating whether the RRC signaling is for an MCG or an SCG, a timing alignment group identifier, a timing advance command, an indicator of a timing alignment timer for a suspended SCG, and the like.

[0086] Additionally or alternatively, the UE 120 may send a physical RACH (PRACH) message in conjunction with the uplink sleep profile of the primary and secondary cells. In this case, the UE 120 may receive a RACH response (RAR) message as a response from the BS 110 (e.g., the primary and secondary cells), the RAR message including a timing alignment indicator in the downlink sleep profile for the primary and secondary cells. In some aspects, after sending the preamble of the PRACH message (which may activate the primary and secondary cells), the UE 120 may monitor for the RAR message in conjunction with the downlink sleep profile for a specific duration (e.g., the duration configured by the radio resource control). Additionally or alternatively, the UE 120 may use RRC signaling (such as a UE assistance information message, which may be a 1-bit request indication regarding the UE 120 requesting to activate the secondary cell group) to activate the primary and secondary cells.

[0087] In some aspects, the RAR message may use a specific format to provide the timing alignment indicator. For example, as shown by reference numbers 703-2 and 703-3, the BS 110 may use a conventional RAR MAC CE or a dedicated RAR MAC CE (e.g., which may include a reserved bit N to indicate whether the timing advance command has a primary PUCCH group or a secondary PUCCH group in a secondary cell group) to convey a timing advance command for identifying the timing alignment indicator. In this case, when the timing alignment timer of the PUCCH secondary cell expires, the UE 120 may release the PUCCH configuration of the PUCCH secondary cell, and may report periodic or semi-persistent channel state information in the PUCCH of the primary and secondary cells.

[0088] As in Fig. 7A As further shown in the figure and by reference numbers 704 and 706, the UE 120 can transmit on the first bandwidth portion using a non-sleep profile and on the second bandwidth portion using a sleep profile. For example, with respect to the second bandwidth portion and on the downlink, the UE 120 can abandon PDCCH monitoring and semi-persistent scheduling communications. In contrast, the UE 120 can perform CSI communications, RRM communications, beam management communications, etc., and can optionally perform beam failure detection on the second bandwidth portion and on the downlink. Similarly, with respect to the second bandwidth portion and on the uplink, the UE 120 can report periodic or semi-persistent CSI messages (e.g., on the PUCCH of the primary cell for the secondary cell in the PUCCH group of the primary cell, and / or on the PUCCH-S-Cell for the secondary cell in the secondary PUCCH group).

[0089] In contrast, UE 120 may forgo periodic SRS communications, PRACH transmissions, scheduling request transmissions, and configured grant transmissions. Additionally or alternatively, UE 120 may stop the timing advance timer when using the sleep state uplink bandwidth portion. Additionally or alternatively, UE 120 may monitor the primary cell when using the second bandwidth portion in the sleep state. For example, UE 120 may monitor for a cross-carrier DCI associated with an indication that UE 120 will switch from using a sleep profile for the second bandwidth portion to using a non-sleep profile for the second bandwidth portion.

[0090] In some aspects, for secondary cell group operation, UE 120 may perform CSI reporting according to a dormant profile. For example, for a dormant profile for secondary cell group operation, UE 120 may report periodic or semi-persistent CSI in a PUCCH of a primary cell (e.g., for a secondary cell in a PUCCH group of a primary cell) and / or in a PUCCH of a secondary cell (e.g., for a secondary cell in a PUCCH group of a secondary cell). Additionally or alternatively, UE 120 may send RRM measurements to BS 110 (e.g., to a primary node (MN)) to enable RRM operation.

[0091] In some aspects, for secondary cell group operation, UE 120 may send and / or receive activation signaling in conjunction with a dormant profile. Figure 7B 8 and as indicated by reference numeral 708, UE 120 may receive signaling indicating that UE 120 will activate a non-dormant profile. For example, UE 120 may receive a cross-cell group DCI from a primary cell indicating that UE 120 will switch from a dormant profile to a non-dormant profile for a primary and secondary cell associated with the second bandwidth portion. In this case, UE 120 may switch to using the non-dormant profile and may use the non-dormant profile to transmit on both the first bandwidth portion and the second bandwidth portion, as indicated by reference numerals 710 and 712.

[0092] Additionally or alternatively, UE 120 may receive a cross-cell group DCI indicating that UE 120 will switch to using a non-dormant profile for a secondary cell in a secondary cell group. Additionally or alternatively, UE 120 may receive a cross-cell group DCI indicating switching to using a dormant profile for a primary secondary cell and a cross-carrier DCI indicating that UE 120 will use a dormant profile for a secondary cell in a secondary cell group.

[0093] In some aspects, UE 120 may receive an RRC message for triggering a switch between a dormant profile (e.g., an associated dormant state) and a non-dormant profile (e.g., an associated non-dormant state). For example, UE 120 may receive an RRC reconfiguration message from a primary cell from BS 110, the RRC reconfiguration message indicating that UE 120 will switch from using a dormant profile to using a non-dormant profile for a primary and secondary cell. Additionally or alternatively, UE 120 may receive an RRC reconfiguration message indicating that UE 120 will switch to using a non-dormant profile for a secondary cell in a secondary cell group. Additionally or alternatively, UE 120 may receive an RRC reconfiguration message indicating that UE 120 will switch to using a non-dormant profile for a primary and secondary cell, and may receive a cross-carrier DCI indicating that UE 120 will switch to using a non-dormant profile for a secondary cell in a secondary cell group.

[0094] In some aspects, for secondary cell group operation, UE 120 may send activation signaling to activate the cell. For example, when UE 120 switches to use a non-dormant profile for the primary cell, UE 120 may send an activation signal to BS 110 so that BS 110 activates the primary and secondary cells. In this case, UE 120 may send an activation signal to primary node (MN) UE 120 via a medium access control (MAC) control element (MAC CE) in an uplink packet. Additionally or alternatively, UE 120 may send an activation signal to the primary and secondary cell BS 110 via a scheduling request of a PUCCH configured by an uplink dormancy profile, via a dedicated RACH configured in an uplink dormancy profile, etc. In this case, the dedicated RACH may be a non-contention RACH of a preamble message or a RACH resource configured in an uplink dormancy profile for the primary and secondary cells. In some aspects, BS 110 may abandon sending a RACH response on, for example, a PDCCH, because UE 120 may not be monitoring the PDCCH.

[0095] In some aspects, UE 120 may begin monitoring for a RACH response based at least in part on sending activation signaling, thereby completing the RACH process. For example, BS 110 (e.g., MN) may receive a RACH preamble for requesting activation of a primary and secondary cell, and may send an activation response to UE 120 (e.g., a secondary node (SN)) via inter-node RRC signaling. In this case, if UE 120 does not receive a RACH response within a threshold amount of time, UE 120 may resend the activation signaling (e.g., via a preamble message).

[0096] As indicated above, Fig. 7A and Figure 7B is provided as an example. Other examples may differ from those described above. Fig. 7A and Figure 7B Examples described.

[0097] Figure 8 8 is a diagram illustrating an example process 800 performed, for example, by a UE in accordance with various aspects of the present disclosure. Example process 800 is an example in which a UE (eg, UE 120, etc.) performs operations associated with secondary cell dormancy using a dormancy profile.

[0098] like Figure 8 As shown, in some aspects, process 800 may include receiving bandwidth portion configuration information for configuring a dormancy profile for a first bandwidth portion of the plurality of bandwidth portions (block 810). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may receive bandwidth portion configuration information for configuring a dormancy profile for a first bandwidth portion of the plurality of bandwidth portions, as described above.

[0099] like Figure 8 As further shown in FIG. 8 , in some aspects, process 800 may include transmitting multiple types of signaling on the second bandwidth portion (block 820). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, etc.) may transmit multiple types of signaling on the second bandwidth portion, as described above.

[0100] like Figure 8 As further shown in FIG. 8 , in some aspects, process 800 may include transmitting a subset of multiple types of signaling over the first bandwidth portion such that at least one type of signaling of the multiple types of signaling is suppressed in accordance with the sleep profile (block 830). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, etc.) may transmit a subset of multiple types of signaling over the first bandwidth portion such that at least one type of signaling of the multiple types of signaling is suppressed in accordance with the sleep profile, as described above.
