Description

[0001] open field

[0002] Various aspects of this disclosure generally relate to wireless communications, and more particularly to techniques and apparatus for measurement configuration during uplink data transmission over random access or dedicated uplink resources.

[0003] background

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that can support communication with multiple users 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 / LTE-Advanced is an enhancement set of the Universal Mobile Telecommunications System (UMTS) mobile standard issued by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include several base stations (BSs) capable of supporting communication between several user equipments (UEs). UEs can communicate with the base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the BS to the UE, while an 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 B-node, gNB, access point (AP), radio headend, transmit / receive point (TRP), new radio (NR) BS, 5G B-node, etc.

[0006] The multiple access technologies mentioned above have been adopted in various telecommunications standards to provide a common protocol enabling different user equipment to communicate at the city, country, region, and even global levels. New Radio (NR) (also known as 5G) is an enhancement set of the LTE mobile standard issued by the 3rd Generation Partnership Project (3GPP). NR is designed to better support mobile broadband internet access by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and better integrating with other open standards that support beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation, using Orthogonal Frequency Division Multiplexing (OFDM) with a Cyclic Prefix (CP) on the downlink (DL) (CP-OFDM), and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Extended OFDM (DFT-s-OFDM)) on the uplink (UL). Further improvements to LTE, NR, and other radio access technologies remain useful as the demand for mobile broadband access continues to grow.

[0029] Detailed description

[0030] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as being limited to any specific structure or function given throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will appreciate that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, any number of aspects set forth herein may be used to implement an apparatus or method of practice. Furthermore, the scope of this disclosure is intended to cover such apparatus or methods practiced using additional structures, functionalities, or structures and functionalities that complement or supplement the various aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be implemented by one or more elements of the claims.

[0031] 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 the following detailed description and explained in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented in hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0032] It should be noted that although the aspects herein may be described using terms commonly associated with 5G or NR radio access technology (RAT), the aspects of this disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or RATs after 5G (e.g., 6G).

[0033] Figure 1This is a diagram illustrating an example of a wireless network 100 according to various aspects of this disclosure. The wireless network 100 may be a 5G (NR) network, an LTE network, etc., or may include elements thereof. The wireless network 100 may include several 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, B-node, gNB, 5G B-node (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 the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0034] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. Macrocells can cover a relatively large geographic area (e.g., a radius of several kilometers) and allow unrestricted access by UEs with a service subscription. Picocells can cover a relatively small geographic area and allow unrestricted access by UEs with a service subscription. Femtocells can cover a relatively small geographic area (e.g., a residential area) and allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed Subscriber Group (CSG)). A BS used for macrocells may be referred to as a macro BS. A BS used for picocells may be referred to as a pico BS. A BS used for femtocells may be referred to as a femto BS or a home BS. Figure 1 In the example shown, 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. A BS may support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “B node,” “5G NB,” and “cell” are used interchangeably herein.

[0035] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs may interconnect with each other and / or interconnect 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, virtual networks, etc.).

[0036] The wireless network 100 may also include a relay station. A relay station is an entity capable of receiving data transmissions from an upstream station (e.g., a BS or a UE) and transmitting those data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay BS110d 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, relay base station, relay, etc.

[0037] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (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 wireless network 100. For example, macro BSs may have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0038] Network controller 130 can be coupled to a set of BSs and can provide coordination and control over these BSs. Network controller 130 can communicate with each BS via backhaul. These BSs can also communicate with each other directly or indirectly, for example, via wireless or wired backhaul.

[0039] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet, camera, gaming device, netbook, smartbook, ultrabook, medical device or equipment, biometric sensor / device, wearable device (smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), entertainment device (e.g., music or video device, or satellite radio), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0040] Some UEs can be considered machine-type communication (MTC) devices, or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, instruments, monitors, location tags, etc., which can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or to a network (e.g., a wide area network, such as the Internet or a cellular network) via wired or wireless communication links, for example. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered client equipment (CPE). UE 120 can be included within a housing that houses the components of UE 120, such as processor components, memory components, etc. In some aspects, the processor components and memory components can be coupled together. For example, the processor components (e.g., one or more processors) and memory components (e.g., memory) can be operatively coupled, communicatively coupled, electronically coupled, electrically coupled, etc.

[0041] 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. A RAT may also be referred to as a radio technology, air interface, etc. A frequency may also be referred to as a carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0042] In some respects, 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 example, UEs 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), mesh networks, etc. In this scenario, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as performed by base station 110.

[0043] Devices in the wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, devices in the wireless network 100 can communicate using an operating band with a first frequency range (FR1) and / or an operating band with a second frequency range (FR2), where the first frequency range (FR1) spans from 410 MHz to 7.125 GHz and the second frequency range (FR2) spans from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as intermediate frequency bands. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as the "sub-6 GHz band." Similarly, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) designated as the "millimeter wave" band by the International Telecommunication Union (ITU), FR2 is often referred to as the "millimeter wave" band. Therefore, unless otherwise stated, it should be understood that, if used herein, the term "sub-6GHz," etc., can broadly refer to frequencies less than 6GHz, frequencies within FR1, and / or intermediate frequency band frequencies (e.g., greater than 7.125GHz). Similarly, unless otherwise stated, it should be understood that, if used herein, the term "millimeter wave," etc., can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or intermediate frequency band frequencies (e.g., less than 24.25GHz). It is conceivable that the frequencies included in FR1 and FR2 can be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0044] As indicated above, Figure 1 This is provided as an example. Other examples may differ from the one provided. Figure 1 The example described.

[0045] Figure 2 This is a diagram illustrating an example 200 of communication between a base station 110 and a UE 120 in a wireless network 100 according to various aspects of this disclosure. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein generally T≥1 and R≥1.

[0046] At base station 110, transmit processor 220 can receive data destined for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on the Channel Quality Indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS(s) selected for each UE, and provide data symbols for all UEs. Transmit processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI) etc.) and control information (e.g., CQI requests, grants, upper-layer signaling, etc.), and provide overhead symbols and control symbols. Transmit processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)), demodulation reference signals (DMRS), etc.) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can process its own output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 can 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 can be transmitted via T antennas 234a to 234t, respectively.

[0047] At UE 120, antennas 252a to 252r can receive downlink signals from base station 110 and / or other base stations and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 can obtain the received symbols from all R demodulators 254a to 254r, perform MIMO detection on these received symbols where applicable, and provide detected symbols. Receiver processor 258 can process (e.g., demodulate and decode) these detected symbols, provide the decoded data for UE 120 to data sink 260, and provide the decoded control information and system information to controller / processor 280. The term "controller / processor" can refer to one or more controllers, one or more processors, or a combination thereof. The channel processor can determine the Reference Received Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Received Quality (RSRQ), Channel Quality Indicator (CQI), and so on. In some respects, one or more components of the UE 120 may be included in the housing 284.

[0048] Network controller 130 may include communication unit 294, controller / processor 290, and memory 292. Network controller 130 may include one or more devices, such as those in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

[0049] On the uplink, at UE 120, transmit processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., reports including RSRP, RSSI, RSRQ, CQI, etc.). Transmit processor 264 can also generate reference symbols for one or more reference signals. Symbols from transmit processor 264 can be pre-encoded by TX MIMO processor 266 where applicable, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to base station 110. In some aspects, UE 120 includes a transceiver. The transceiver may include (e.g.) antenna 252, modulator and / or demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or any combination of TX MIMO processor 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, for example, as referenced Figure 6-11 As described.

[0050] At base station 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 where applicable, and further processed by receiver processor 238 to obtain decoded data and control information transmitted by UE 120. Receiver processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antenna 234, modulator and / or demodulator 232, MIMO detector 236, receiver processor 238, transmitter processor 220, and / or TXMIMO processor 230. The transceiver can be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein, for example, as referenced Figure 6-11 As described.

[0051] The controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component may perform one or more techniques associated with measurement configuration during uplink data transmission on random access or dedicated uplink resources, as described in more detail elsewhere herein. For example, the controller / processor 240 of base station 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component may execute or direct, for example Figure 10 Process 1000 Figure 11 The operation of process 1100 and / or other processes as described herein. Memory 242 and 282 may store data and program code for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include: a non-transitory computer-readable medium storing one or more instructions (e.g., code, program code, etc.) for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly executed, or executed after compilation, conversion, interpretation, etc.), the one or more processors, UE 120, and / or base station 110 may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example... Figure 10 Process 1000 Figure 11The process 1100, and / or other processes as described herein. In some respects, the execution instructions may include run instructions, translate instructions, compile instructions, interpret instructions, etc.

[0052] In some aspects, UE 120 may include: means for determining uplink data to be transmitted in an inactive state; means for determining a measurement gap configuration for a cell reselection procedure to be executed during uplink data transmission in an inactive state; means for executing the cell reselection procedure according to the measurement gap configuration; and so on. In some aspects, such means may include combinations of... Figure 2 One or more components of the described UE 120, 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.

[0053] In some aspects, base station 110 may include: means for receiving from the UE an indication that uplink data will be transmitted while the UE is in an inactive state; means for transmitting to the UE a measurement gap configuration for a cell reselection procedure to be performed during the transmission of uplink data by the UE in an inactive state; and so on. In some aspects, such means may include combined with Figure 2 One or more components of the described base station 110, such as antenna 234, DEMOD 232, MIMO detector 236, receiver processor 238, controller / processor 240, transmitter processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.

[0054] although Figure 2 The boxes in the diagram are interpreted as different components, but the functions described above with respect to these boxes can be implemented by a single hardware component, software component, or combination of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 can be performed by controller / processor 280 or under the control of controller / processor 280.

[0055] As indicated above, Figure 2 This is provided as an example. Other examples may differ from the one provided. Figure 2 The example described.

[0056] Figure 3Example 300 illustrates a wireless network (e.g., wireless network 100) according to various aspects of this disclosure, in which a UE (e.g., UE 120) can support additional communication modes. The UE can communicatively connect to one or more base stations in the wireless network. For example, the UE can connect to one or more base stations in a dual connectivity configuration. In this case, a first base station can serve the UE as a primary node, and a second base station can serve the UE as a secondary node.

[0057] As in Figure 3 As explained, the UE can support connected communication modes (e.g., Radio Resource Control (RRC) active mode 302), idle communication modes (e.g., RRC idle mode 304), inactive communication modes (e.g., RRC inactive mode 306), etc. RRC inactive mode 306 can functionally reside between RRC active mode 302 and RRC idle mode 304.

[0058] The UE can switch between different modes, at least in part, based on various commands and / or communications received from one or more base stations. For example, the UE can switch from RRC active mode 302 or RRC inactive mode 306 to RRC idle mode 304, at least in part, based on receiving an RRC Release communication. As another example, the UE can switch from RRC active mode 302 to RRC inactive mode 306, at least in part, based on receiving an RRC Setup Request communication. As another example, the UE can switch from RRC idle mode 304 to RRC active mode 302, at least in part, based on receiving an RRC Setup Request communication. As yet another example, the UE can switch from RRC inactive mode 306 to RRC active mode 302, at least in part, based on receiving an RRC Resume Request communication.

[0059] When transitioning to RRC inactive mode 306, the UE and / or one or more base stations may store the UE context (e.g., Access Layer (AS) context, higher layer configuration, etc.). This allows the UE and / or one or more base stations to apply the stored UE context to resume communication with one or more base stations when the UE transitions from RRC inactive mode 306 to RRC active mode 302, which reduces the waiting time for transitioning to RRC active mode 302 compared to transitioning from RRC idle mode 304 to RRC active mode 302.

[0060] In some scenarios, when transitioning from RRC idle mode 304 or RRC inactive mode 306 to RRC active mode 302, the UE can communicatively connect to a new primary node (e.g., a different primary node from the one last served when the UE transitioned to RRC idle mode 304 or RRC inactive mode 306). In this scenario, the new primary node can be responsible for identifying the secondary node for the UE in the dual connectivity configuration.

[0061] As indicated above, Figure 3 This is provided as an example. Other examples may differ from the one provided. Figure 3 The example described.

[0062] Figure 4 This is a diagram illustrating Example 400 of a two-step random access procedure according to various aspects of this disclosure. For example... Figure 4 As shown, base station 110 and UE 120 can communicate with each other to perform a two-step random access procedure.

[0063] As indicated by reference numeral 405, base station 110 can transmit and UE 120 can receive one or more synchronization signal blocks (SSBs) and random access configuration information. In some aspects, the random access configuration information may be transmitted and / or indicated by system information (e.g., one or more system information blocks (SIBs)) and / or SSBs, such as for contention-based random access. Additionally or alternatively, the random access configuration information may be transmitted in radio resource control (RRC) messages and / or physical downlink control channel (PDCCH) command messages that trigger a random access channel (RACH) procedure, such as for contention-free random access. The random access configuration information may include one or more parameters to be used in a two-step random access procedure, such as one or more parameters for transmitting a random access message (RAM), receiving a random access response (RAR) to the RAM, etc.

[0064] As shown by reference numeral 410, UE 120 can transmit and base station 110 can receive a RAM preamble. As shown by reference numeral 415, UE 120 can transmit and base station 110 can receive a RAM payload. As shown, as part of the initial (or first) step of a two-step random access procedure, UE 120 can transmit a RAM preamble and a RAM payload to base station 110. In some aspects, RAM may be referred to as message A, msgA, first message, initial message, etc., in a two-step random access procedure. Furthermore, in some aspects, RAM preamble may be referred to as message A preamble, msgA preamble, preamble, physical random access channel (PRACH) preamble, etc., and RAM payload may be referred to as message A payload, msgA payload, payload, etc. In some aspects, RAM may include some or all of the contents of message 1 (msg1) and message 3 (msg3) of a four-step random access procedure, which are described in detail below. For example, the RAM preamble may include some or all of the contents of message 1 (e.g., PRACH preamble), and the RAM payload may include some or all of the contents of message 3 (e.g., UE identifier, uplink control information (UCI), physical uplink shared channel (PUSCH) transmission, etc.).

[0065] As indicated by reference numeral 420, base station 110 can receive the RAM preamble transmitted by UE 120. If base station 110 successfully receives and decodes the RAM preamble, base station 110 can then receive and decode the RAM payload.

[0066] As shown by reference numeral 425 in the attached figure, base station 110 can transmit a RAR (sometimes referred to as a RAR message). As shown, base station 110 can transmit a RAR message as part of the second step of a two-step random access procedure. In some aspects, the RAR message may be referred to as message B, msgB, or the second message in the two-step random access procedure. The RAR message may include some or all of the contents of messages 2 (msg2) and 4 (msg4) of the four-step random access procedure. For example, the RAR message may include the detected RACH preamble identifier, the detected UE identifier, timing advance value, contention resolution information, etc.

[0067] As indicated by reference numeral 430, as part of the second step of the two-step random access procedure, base station 110 may transmit Physical Downlink Control Channel (PDCCH) communications for the RAR. PDCCH communications may schedule Physical Downlink Shared Channel (PDSCH) communications that include the RAR. For example, PDCCH communications may indicate resource allocation for PDSCH communications (e.g., in Downlink Control Information (DCI)).

[0068] As shown by reference numeral 435, as part of the second step of the two-step random access procedure, base station 110 may transmit PDSCH communication for RAR, as scheduled by PDCCH communication. RAR may be included in the Media Access Control (MAC) Protocol Data Unit (PDU) of the PDSCH communication. As shown by reference numeral 440, if UE 120 successfully receives RAR, UE 120 may transmit a Hybrid Automatic Repeat Request (HARQ) acknowledgment (ACK).

[0069] As indicated above, Figure 4 This is provided as an example. Other examples may differ from the one provided. Figure 4 The example described.

[0070] Figure 5 This is a diagram illustrating Example 500 of a four-step random access procedure according to various aspects of this disclosure. For example... Figure 5 As shown, base station 110 and UE 120 can communicate with each other to perform a four-step random access procedure.

[0071] As indicated by reference numeral 505, base station 110 can transmit and UE 120 can receive one or more SSBs, as well as random access configuration information. In some aspects, the random access configuration information may be transmitted and / or indicated by system information (e.g., one or more SSBs, etc.) and / or SSBs, such as for contention-based random access. Additionally or alternatively, the random access configuration information may be transmitted in RRC messages and / or PDCCH command messages that trigger RACH procedures, such as for contention-free random access. The random access configuration information may include one or more parameters to be used in the random access procedure, such as one or more parameters for transmitting RAM, one or more parameters for receiving RAR, etc.

[0072] As shown by reference numeral 510 in the attached figure, UE 120 can transmit RAM, which may include a preamble (sometimes referred to as a random access preamble, PRACH preamble, RAM preamble, etc.). Messages including preambles may be referred to as Message 1, msg1, MSG1, First Message, Initial Message, etc., in the four-step random access procedure. Random access messages may include a random access preamble identifier.

[0073] As indicated by reference numeral 515, base station 110 may transmit a RAR as a response to the preamble. The message including the RAR may be referred to as message 2, msg2, MSG2, or the second message in the four-step random access procedure. In some aspects, the RAR may indicate the detected random access preamble identifier (e.g., received from UE 120 in msg1). Additionally or alternatively, the RAR may indicate the resource allocation to be used by UE 120 for transmitting message 3 (msg3).

[0074] In some respects, as part of the second step of the four-step random access procedure, base station 110 may transmit PDCCH communications for the RAR. This PDCCH communication may schedule PDSCH communications that include the RAR. For example, the PDCCH communication may indicate resource allocation for the PDSCH communication. Also as part of the second step of the four-step random access procedure, base station 110 may transmit PDSCH communications for the RAR, as scheduled by the PDCCH communication. The RAR may be included in the MAC PDU of the PDSCH communication.

[0075] As shown by reference numeral 520, UE 120 may transmit an RRC connection request message. The RRC connection request message may be referred to as message 3, msg3, MSG3, or the third message of the four-step random access procedure. In some aspects, the RRC connection request may include the UE identifier, UCI, PUSCH communication (e.g., RRC connection request), etc.

[0076] As shown by reference numeral 525, base station 110 may transmit an RRC connection establishment message. The RRC connection establishment message may be referred to as message 4, msg4, MSG4, or the fourth message of the four-step random access procedure. In some aspects, the RRC connection establishment message may include the detected UE identifier, timing advance value, contention resolution information, etc. As shown by reference numeral 530, if UE 120 successfully receives the RRC connection establishment message, UE 120 may transmit a HARQ ACK.

[0077] As indicated above, Figure 5 This is provided as an example. Other examples may differ from the one provided. Figure 5 The example described.

[0078] The UE can enter an inactive state (such as RRC inactive state) to conserve battery power and network resources during infrequent data traffic. "Inactive state" can refer to an inactive communication mode (e.g., RRC inactive mode, as described above). Figure 3 The UE operates as described above. The transition from an inactive state to an active state may involve a Random Access Channel (RACH) procedure or another form of establishment procedure. In many applications, the UE may generate only a small amount of data in a data session burst. Examples of such applications include enhanced mobile broadband (eMBB) communications, Internet of Things (IoT) communications, instant messaging applications, social media applications, wearable device applications, etc. Figure 4 and Figure 5The RACH procedure shown can consume significant resources for both the UE and the network when establishing an RRC connection. Therefore, in some scenarios, establishing an RRC connection for uplink data transmission can be inefficient. For example, re-establishing an RRC connection simply to transmit small data bursts may waste both UE and network resources.

[0079] Some radio access technologies can provide services for transmitting small data transmissions in inactive modes, such as via uplink RACH messages or configured uplink resources (e.g., dedicated pre-configured uplink resources, pre-configured uplink resources, dedicated uplink resources, etc.). However, not all small data transmissions are suitable for uplink RACH messages or configured uplink resources. Furthermore, in some cases, uplink resources may not be configured for the UE. Therefore, providing small data transmissions via uplink RACH messages or configured uplink resources (e.g., regardless of the size of the data transmission or configured uplink resources) may result in failed uplink transmissions, retransmissions, etc.

[0080] Therefore, in some situations, small data transmissions using uplink RACH messages or configured uplink resources can be based at least in part on one or more size thresholds (e.g., transport block size (TBS) thresholds, etc.). For example, if the uplink data fails to meet a size threshold (e.g., less than or equal to, or less than the size threshold), the UE can transmit the uplink data via uplink RACH messages or configured uplink resources (e.g., at least in part on one or more other thresholds or another value associated with the size threshold) without establishing an RRC connection. In this way, the UE can reduce signaling overhead and latency caused by establishing and releasing RRC connections for transmitting uplink data. If the uplink data meets a size threshold (e.g., greater than, or greater than or equal to the size threshold), the UE can establish an RRC connection to transmit the uplink data. In this way, the UE can selectively provide uplink data via uplink RACH resources or configured uplink resources, at least in part, based on the size of the uplink data.

[0081] Figure 6-8 Examples 600, 700, and 800 illustrate examples of uplink data transmission on random access or dedicated uplink resources according to various aspects of this disclosure. Examples 600 and 700 illustrate two-step and four-step RACH procedures, respectively, in which UE 120 transmits uplink data in inactive mode. Example 800 illustrates UE 120 transmitting uplink data in inactive mode using pre-configured uplink resources (e.g., configured to grant uplink resources).

[0082] As in Figure 6 As shown by reference numeral 610 in the accompanying drawing, UE 120 may transmit an RRC recovery request in RACH msgA. As further shown, the RRC recovery request may include a configured uplink resource (CUR) request, such as a MAC control element (MAC-CE) indicating a CUR request. In some aspects, the RRC parameters of the RRC message (e.g., the RRCResumeRequest parameter, etc.) may indicate the amount of data transmitted and / or the traffic mode associated with the data transmission. In some aspects, the CUR request may include a recovery identifier, an authentication token (e.g., shortResumeMac-I or recovery MAC-I), etc.

[0083] CUR configurations may include configured uplink resources, pre-configured uplink resources, dedicated uplink resources, and dedicated pre-configured uplink resources (D-PUR). A CUR configuration can be a resource on which the UE 120 can perform uplink transmissions without entering RRC connected mode or RRC active mode. In some aspects, a CUR configuration may have a TBS sufficient to transmit data in a single transport block, referred to as a single-transmission CUR. In some aspects, a CUR configuration may include multiple resources distributed in the time domain, allowing the UE 120 to transmit uplink data after initial uplink data transmission, or to transmit uplink data on these multiple resources; this is referred to as a multiple-transmission CUR. In some aspects, multiple-transmission CURs may include configured-permitted CURs, periodic CURs, semi-persistent CURs, etc.

[0084] As shown in Example 600, a CUR request can request multiple CURs. As indicated by reference numeral 620, UE 120 can receive CUR configuration (e.g., configuration information for configuring the CUR) via a RACH message (such as an RRC release message carried by RACH msgB). As indicated by reference numeral 630, UE 120 can monitor a UE-specific search space (USS) associated with the CUR. For example, the USS may carry control information associated with a specific UE (here, UE 120). Thus, UE 120 can monitor the USS to look for scheduling information associated with transmitting uplink data, subsequent uplink data, retransmission of uplink data, etc. For example, as indicated by reference numeral 640, UE 120 can transmit uplink data on a CUR configured via CUR configuration (e.g., at least partially based on receiving scheduling information in the USS indicating the transmission of uplink data on that CUR). Furthermore, as indicated by reference numeral 650 in the accompanying drawings, UE 120 may transmit subsequent uplink data on the CUR (e.g., at least part of the base station receives scheduling information in the USS instructing the transmission of subsequent uplink data on the CUR). Figure 6 Example 600 can be used in conjunction with a two-step RACH procedure to explain the procedure for requesting a CUR and performing multiple transmissions of uplink data in inactive mode.

[0085] like Figure 7 As shown by reference numeral 710, UE 120 may transmit RACH msg1 to base station 110. As shown by reference numeral 720, base station 110 may transmit RACH msg2 to UE 120. As shown by reference numeral 730, UE 120 may transmit an RRC recovery request in RACH msg3. As further shown, the RRC recovery request may include a CUR request, such as a MAC-CE indicating a CUR request. In this case, the CUR request may request multiple CURs, as described in more detail elsewhere herein. As shown by reference numeral 740, UE 120 may receive CUR configuration (e.g., configuration information for configuring a CUR) via RACH messages (such as an RRC release message carried by RACH msg4). As shown by reference numeral 750, UE 120 may monitor the USS associated with the CUR. As shown by reference numeral 760, UE 120 can transmit uplink data on a CUR configured via CUR configuration (e.g., at least a portion of the base station receives scheduling information in the USS instructing the transmission of uplink data on that CUR). Furthermore, as shown by reference numeral 770, UE 120 can transmit subsequent uplink data on that CUR (e.g., at least a portion of the base station receives scheduling information in the USS instructing the transmission of subsequent uplink data on that CUR). Figure 7 Example 700 can be used in conjunction with the four-step RACH procedure to explain the procedure for requesting CUR and performing multiple transmissions of uplink data in inactive mode.

[0086] like Figure 8As shown by reference numeral 810, base station 110 can transmit a pre-configured uplink resource (PUR) configuration (e.g., configuration information configuring the PUR), and UE 120 can receive this PUR configuration. In some aspects, base station 110 can transmit the PUR configuration via a RACH message (such as an RRC release message). In some aspects, the PUR can be a configured granted uplink resource, a D-PUR, etc. As shown by reference numeral 820, UE 120 can transmit an RRC recovery request that includes a CUR request on the PUR. In this case, the CUR request may request multiple CURs, as described in more detail elsewhere herein. As shown by reference numeral 830, UE 120 can receive the CUR configuration (e.g., configuration information configuring the CUR) via an RRC release message. As shown by reference numeral 840, UE 120 can monitor the USS associated with the CUR. As shown by reference numeral 850, UE 120 can transmit uplink data on a CUR configured by the CUR configuration (e.g., at least part of the base station receives scheduling information in the USS instructing the transmission of uplink data on that CUR). As shown by reference numeral 860, UE 120 can receive downlink data from base station 110 (e.g., at least partly based on receiving scheduling information in the USS instructing the reception of downlink data). Furthermore, as shown by reference numeral 870, UE 120 can transmit subsequent uplink data on that CUR (e.g., at least part of the base station receives scheduling information in the USS instructing the transmission of subsequent uplink data on that CUR). Figure 8 Example 800 can be used in conjunction with PUR to explain the procedure for requesting CUR and performing multiple transmissions of uplink data in inactive mode.

[0087] As indicated above, Figure 6-8 This is provided as an example. Other examples may differ from the one provided. Figure 6-8 The example described.

[0088] In some wireless networks, a UE can be configured by the base station of the serving cell to perform measurements on one or more neighboring cells. For example, the UE can be configured to perform intra-frequency measurements (e.g., the serving cell and one or more neighboring cells can operate using the same operating frequency and the same subcarrier spacing (SCS), inter-frequency measurements (e.g., the serving cell can operate using a first operating frequency (and / or a first SCS), and one or more neighboring cells can operate using a second operating frequency (and / or a second SCS), inter-Radio Access Technology (RAT) measurements (e.g., the serving cell can be associated with a first RAT, and one or more neighboring cells can be associated with a second RAT), and so on. In some aspects, the UE may need to tune its radio frequency (RF) components to enable the UE to perform measurements in a target frequency band (e.g., a band used by neighboring cells). As a result, when the UE is tuned to the target frequency band, communication in the serving frequency band (e.g., a band used by the serving cell) may be interrupted. Therefore, the base station of the serving cell can be configured with measurement gaps (e.g., during which the UE does not transmit and / or receive communications associated with the serving cell), during which the UE may be able to perform measurements on one or more neighboring cells.

[0089] For the UE, during small data transmission periods (e.g., as mentioned above), Figure 6-8 Continuing cell reselection measurements and cell reselection assessments (e.g., cell reselection procedures) can be beneficial. For example, in cases where the UE is transmitting subsequent uplink data in inactive mode, it is advantageous to maintain UE mobility by allowing the UE to continue performing cell reselection procedures during small data transmissions. However, when the UE is in an inactive mode (e.g., RRC inactive mode), the serving cell may not be configured or enabled for measurement gap-based measurements. As described above, the UE can monitor the USS while in inactive mode to look for scheduling information associated with uplink data transmission. As a result, without any configured measurement gaps, if the UE is performing cell reselection measurements when scheduling information is transmitted in the USS, the scheduling information transmitted in the USS may not be received by the UE.

[0090] Some of the techniques and apparatus described herein enable measurement gap configuration during uplink data transmission on random access or dedicated uplink resources. For example, a base station can configure measurement gaps for a UE in a RACH message (such as MsgB of a two-step RACH protocol or message 4 of a four-step RACH protocol). In some aspects, the base station can determine the measurement gap configuration based at least in part on the traffic pattern associated with small data transmissions performed by the UE in inactive mode (e.g., indicated by the UE in an uplink RACH message or an uplink RRC message). In some cases, the UE can indicate measurement gap requirement information in a RACH message (such as MsgA of a two-step RACH protocol or message 3 of a four-step RACH protocol). In some aspects, the UE can determine one or more autonomous measurement gaps (e.g., autonomous measurement gaps can be measurement gaps determined by the UE without measurement gap configuration from the base station, measurement gaps determined by the UE by modifying measurement gaps configured by the base station, etc.) for performing measurements associated with a cell reselection procedure during small data transmissions in inactive mode. In some aspects, the UE can be configured to use previously performed measurements (e.g., measurements performed before transmitting uplink data in inactive mode) during small data transmissions in inactive mode in the cell reselection procedure. As a result, the UE can perform the cell reselection procedure during small data transmissions in inactive mode, thereby improving UE mobility, communication reliability, and so on. Furthermore, the UE can be configured with measurement gaps so that scheduling information transmitted in the USS during small data transmissions in inactive mode is not missed by the UE because the UE is performing measurements associated with the cell reselection procedure. This improves reliability and reduces latency associated with small data transmissions in inactive mode.

[0091] Figure 9 This is a diagram illustrating example 900 associated with a measurement configuration during uplink data transmission on random access or dedicated uplink resources, according to various aspects of this disclosure. Figure 9 As shown, Example 900 includes communication between base station 110 and UE 120. In some aspects, base station 110 and UE 120 may be included in a wireless network (such as wireless network 100). Base station 110 and UE 120 may communicate on a radio access link, which may include uplink and downlink. Example 900 illustrates an example in which UE 120 has been determined to transmit uplink data (e.g., small data transmission) during RACH procedures (e.g., two-step RACH procedures or four-step RACH procedures) or on a PUR in an inactive mode (e.g., RRC inactive mode) or on a PUR.

[0092] As shown by reference numeral 910 in the attached figure, UE 120 can transmit, and base station 110 can receive, a CUR request for a CUR to be used for transmitting uplink data. UE 120 can transmit the CUR request using uplink RACH messages (e.g., MsgA of a two-step RACH protocol, message 3 of a four-step RACH protocol, etc.) or using PURs (e.g., configured to grant uplink resources, D-PUR, etc.). In some aspects, UE 120 can transmit the CUR request in MAC-CE. As described above, the CUR request can indicate the buffer status information of UE 120, the traffic mode associated with the uplink data to be transmitted (e.g., single transmission, multiple transmissions, single transmission, multiple transmissions, periodic transmission, semi-persistent transmission, etc.), the periodicity associated with the uplink data to be transmitted, the size of the uplink data to be transmitted, etc.

[0093] In some aspects, communications transmitted by UE 120 using uplink RACH messages or PURs can indicate measurement gap requirement information (e.g., the NeedForGapsInfoNR parameter of the RRC recovery procedure) associated with performing cell reselection procedures during uplink data transmission in inactive mode. Measurement gap requirement information can be indicated in RRC parameters of the RRC recovery request (RRCResumeRequest parameter, NeedForGapsInfoNR parameter, needForGapsConfigNR parameter, etc.), in the RRC message, in the CUR request, etc. Measurement gap requirement information can indicate measurement gap information for a target frequency band associated with the cell reselection procedure (e.g., the target frequency band in which UE 120 will perform measurements associated with the cell reselection procedure). Measurement gap requirement information can indicate a measurement gap pattern or periodicity. Measurement gap requirement information can indicate the measurement gap capability of UE 120 (e.g., the number or frequency of measurement gaps that UE 120 can support).

[0094] As indicated by reference numeral 920, base station 110 may determine a measurement gap configuration associated with a cell reselection procedure performed by UE 120 during uplink data transmission in inactive mode. In some aspects, base station 110 may determine the measurement gap configuration at least in part based on a CUR request. For example, base station 110 may determine the measurement gap configuration at least in part based on the traffic mode of the uplink data indicated in the CUR request. Base station 110 may determine the traffic mode of the uplink data at least in part based on explicit indications in the CUR request. In some aspects, base station 110 may determine the traffic mode of the uplink data at least in part based on buffer state information indicated in the CUR request.

[0095] In some aspects, if the CUR request indicates that uplink data should be transmitted in a single instance (e.g., single traffic, a single uplink transmission on the CUR, etc.), base station 110 can determine that a measurement gap does not need to be configured (e.g., because base station 110 can configure UE 120 to perform measurements during a measurement gap following a single uplink transmission). In some aspects, if the CUR request indicates that uplink data should be transmitted in multiple instances (e.g., multiple traffic, periodic uplink transmissions on the CUR, semi-persistent uplink transmissions on the CUR, etc.), base station 110 can determine one or more measurement gaps during which UE 120 performs measurements associated with the cell reselection procedure. Base station 110 can determine one or more measurement gaps based at least in part on the timing, pattern, or periodicity of the uplink transmission.

[0096] In some aspects, base station 110 may determine the measurement gap configuration based at least in part on measurement gap requirement information indicated by UE 120. For example, base station 110 may determine the measurement gap configuration based at least in part on an indication of measurement gap requirements received from UE 120. Base station 110 may determine one or more measurement gaps during which UE 120 performs measurements associated with the cell reselection procedure, based at least in part on information indicated by the measurement gap requirement information.

[0097] As indicated by reference numeral 930, base station 110 may transmit CUR configuration (e.g., configuration information for configuring the CUR) via an RRC release message carried by a downlink RACH message or a downlink RRC message, and UE 120 may receive the CUR configuration via the RRC release message. In some aspects, if base station 110 determines to configure one or more measurement gaps, then communication (e.g., carried by a downlink RACH message or a downlink RRC message) may indicate the measurement gap configuration. The measurement gap configuration may be indicated in parameters (e.g., the measGapConfig parameter, etc.) of the downlink RACH message or downlink RRC message.

[0098] In some aspects, base station 110 may determine that no measurement gap will be configured during uplink data transmission. In some aspects, base station 110 may configure UE 120 to perform cell reselection procedures during uplink data transmission, without performing measurements during uplink data transmission. For example, base station 110 may configure UE 120 to perform cell reselection evaluation procedures during uplink data transmission using measurements of one or more neighboring cells performed prior to uplink data transmission. In some aspects, base station 110 may instruct UE 120 in a downlink RACH message or downlink RRC message to perform cell reselection evaluation procedures during uplink data transmission using measurements of one or more neighboring cells performed prior to uplink data transmission.

[0099] As shown by reference numeral 930, UE 120 can monitor the USS associated with the CUR. For example, the USS may carry control information associated with a specific UE (here, UE 120). Thus, UE 120 can monitor the USS to locate scheduling information associated with transmitting uplink data, subsequent uplink data transmissions, and retransmissions of uplink data. For example, UE 120 can monitor the control channel (e.g., PDCCH) within the USS associated with the CUR that is associated with a specific Radio Network Temporary Identifier (RNTI) (e.g., Cellular RNTI (C-RNTI), Inactive RNTI (I-RNTI), or another type of RNTI). As shown by reference numeral 940, UE 120 can transmit uplink data on the CUR configured by the CUR configuration (e.g., at least partially based on receiving scheduling information in the USS instructing the transmission of uplink data on that CUR).

[0100] As shown by reference numeral 950 in the attached figure, UE 120 may perform a cell reselection procedure during uplink data transmission in inactive mode. In some aspects, UE 120 may perform the cell reselection procedure according to the measurement interval configuration. The cell reselection procedure may be an inter-frequency cell reselection procedure, an intra-frequency cell reselection procedure, or an inter-RAT cell reselection procedure.

[0101] For example, UE 120 may determine a measurement gap configuration for the cell reselection procedure. UE 120 may determine the measurement gap configuration for the cell reselection procedure based at least in part on an indication of the measurement gap configuration received from base station 110 (e.g., as described above). UE 120 may determine one or more measurement gaps indicated by the measurement gap configuration. UE 120 may perform one or more measurements on one or more neighboring cells during the measurement gap. UE 120 may perform the cell reselection evaluation procedure based at least in part on measurement values ​​determined by performing the one or more measurements. In some aspects, UE 120 may indicate measurement values ​​to base station 110 to enable base station 110 to initiate a handover procedure as part of the cell reselection procedure (e.g., if the measurement values ​​indicate that the serving cell should be changed from the cell associated with base station 110 to a neighboring cell).

[0102] In some respects, the communications described above with respect to reference numerals 910 and 930 may not include information associated with measurement gap configuration (e.g., UE 120 may not transmit measurement gap requirement information and / or base station 110 may not transmit measurement gap configuration). In this case, UE 120 may be able to determine one or more autonomous measurement gaps for performing measurements associated with a cell reselection procedure. For example, the USS used to monitor the control channel with a specific RNTI may be sufficiently sparse (e.g., if the USS has few PDCCH candidates, etc.) so that UE 120 can perform measurement gap-based measurements without explicit indication of measurement gaps from base station 110. UE 120 may determine one or more autonomous measurement gaps at least in part based on the configuration of the USS. UE 120 may perform one or more measurements on one or more neighboring cells during an autonomous measurement gap. UE 120 may perform a cell reselection evaluation procedure at least in part based on the measurement values ​​determined by performing such one or more measurements. In some respects, UE 120 may indicate the measurement value to base station 110 so that base station 110 can initiate a handover procedure as part of the cell reselection procedure (e.g., if the measurement value indicates that the serving cell should be changed from the cell associated with base station 110 to a neighboring cell).

[0103] In some aspects, as described above, UE 120 can be configured to use measurements of one or more neighboring cells performed before uplink data transmission during a cell reselection procedure. For example, UE 120 may not need to perform measurements during uplink data transmission. Instead, UE 120 may perform a cell reselection evaluation procedure based at least in part on measurement values ​​determined by performing measurements of one or more neighboring cells performed before uplink data transmission. In some aspects, UE 120 may indicate the measurement values ​​to base station 110 so that base station 110 can initiate a handover procedure as part of the cell reselection procedure (e.g., if the measurement values ​​indicate that the serving cell should be changed from the cell associated with base station 110 to a neighboring cell).

[0104] As indicated by reference numeral 960, UE 120 may transmit subsequent uplink data on the CUR (e.g., at least a portion of the base station receives scheduling information in the USS instructing the transmission of subsequent uplink data on the CUR). In some aspects, subsequent uplink data on the CUR may be associated with different serving cells (e.g., may be transmitted to different base stations 110). For example, a handover procedure may be initiated to switch UE 120 from the current serving cell (e.g., associated with base station 110) to a new serving cell (e.g., a neighboring cell associated with a different base station 110) by performing a cell reselection procedure. In some aspects, subsequent uplink data on the CUR may be associated with the same serving cell (e.g., may be transmitted to base station 110), and a handover procedure may be initiated to switch UE 120 from the current serving cell to a new serving cell after the transmission of subsequent uplink data.

[0105] As a result, UE 120 can perform cell reselection procedures during small data transmissions in inactive mode, thereby improving UE mobility, communication reliability, and more. Furthermore, UE 120 can be configured with measurement gaps so that scheduling information transmitted in the USS during small data transmissions in inactive mode is not missed by UE 120 because UE 120 is performing measurements associated with cell reselection procedures. This improves reliability and reduces latency associated with small data transmissions in inactive mode.
