The UE can transmit a scheduling request for resources to transmit the data buffered for transmission via the first logical channel via a scheduling request resource of a second logical channel that has a valid scheduling request configuration. Numerous other aspects are described.

Description

Technical Field

[0001] Aspects of the present disclosure relate generally to wireless communications and techniques and apparatus for obtaining uplink resources for a logical channel without an associated scheduling request configuration. Background Art

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0003] A wireless network may include many base stations (BSs) that can support communications for many user equipment (UEs). User equipment (UEs) can communicate with a base station (BS) via downlinks and uplinks. The downlink (or forward link) refers to the communication link from the BS to the UE, while the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0004] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at the city, country, regional, and even global levels. New Radio (NR), also known as 5G, is a set of enhancements to the LTE mobile standard released by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL), CP-OFDM and / or SC-FDM (e.g., also known 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 improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to increase, further improvements to LTE, NR, and other radio access technologies remain useful. SUMMARY

[0005] In some aspects, a method of wireless communication performed by a user equipment (UE) includes determining that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration; and transmitting a scheduling request for resources to transmit the data buffered for transmission via the first logical channel via a scheduling request resource of a second logical channel that has a valid scheduling request configuration.

[0006] In some aspects, a UE for wireless communication includes a memory; and one or more processors operatively coupled to the memory, the memory and the one or more processors configured to: determine that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration; and transmit a scheduling request for resources to transmit the data buffered for transmission via the first logical channel via a scheduling request resource of a second logical channel that has a valid scheduling request configuration.

[0007] In some aspects, a non-transitory computer-readable medium storing a set of instructions for wireless communication includes one or more instructions that, when executed by one or more processors of a UE, cause the UE to: determine that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration; and transmit a scheduling request for resources to transmit the data buffered for transmission via the first logical channel via a scheduling request resource of a second logical channel that has a valid scheduling request configuration.

[0008] In some aspects, an apparatus for wireless communication includes means for determining that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration; and means for transmitting a scheduling request for resources to transmit the data buffered for transmission via the first logical channel via a scheduling request resource of a second logical channel that has a valid scheduling request configuration.

[0018] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, 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. Based on the teachings herein, it should be understood by those skilled in the art that, regardless of 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, the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein. For example, a device or practice method can be implemented with any number of aspects set forth herein. In addition, the scope of the present disclosure is intended to cover such a device or method that uses other structures, functions, or structures and functions that are additional or different from the various aspects of the present disclosure set forth herein to practice. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0019] Several aspects of telecommunications systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively, "elements"). These elements can be implemented in hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0020] It should be noted that although terms generally associated with 5G or NR radio access technology (RAT) may be used herein to describe aspects, aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT, and / or RATs beyond 5G (e.g., 6G).

[0021] Figure 1 is a diagram illustrating an example of a wireless network 100 according to various aspects of the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, among other examples. The wireless network 100 may include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, Node B, gNB, 5G Node B (NB), access point, 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 that coverage area, depending on the context in which the term is used.

[0022] A BS can provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell can cover a relatively large geographic area (e.g., several kilometers in radius) and can allow unrestricted access by UEs with service subscriptions appropriate for the Figure 1 In the example shown in FIG. 1, 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 can support one or multiple (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” can be used interchangeably herein.

[0023] In some aspects, a cell can not necessarily be stationary, and the geographic area of the cell can move according to the location of a mobile BS. In some aspects, a BS can be interconnected to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any appropriate transfer means.

[0024] Wireless network 100 can also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. In Figure 1 In the example shown in FIG. 1, a relay BS 1 lOd can communicate with macro BS 110a and a UE 120d in order to facilitate communications between BS 110a and UE 120d. A relay BS can also be referred to as a relay station, a relay base station, a relay, or the like.

[0025] Wireless network 100 can be a heterogeneous network that includes BSs of different types, such as macro BSs, pico BSs, femto BSs, relay BSs, or the like. These different types of BSs can have different transmit power levels, different coverage areas, and different impacts on interference. For example, macro BSs can have a high transmit power level (e.g., 5 to 40 Watts) whereas pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 Watts).

[0026] A network controller 130 can couple to a set of BSs and can provide coordination and control for these BSs. Network controller 130 can be in communication with the BSs via a backhaul. The BSs can also communicate with one another, e.g., directly or indirectly via a wireless or wireline backhaul.

[0027] UEs 120 (e.g., 120a, 120b, 120c) can be dispersed throughout wireless network 100, and each UE can be stationary or mobile. A UE can also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, etc. A UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicular component or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium.

[0028] Some UEs can be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, e.g., robots, drones, remote devices, sensors, meters, monitors, and / or location tags, that can communicate with a base station, another device (e.g., remote device), or some other entity. A wireless node can provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. 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 Customer Premises Equipment (CPE). UE 120 can be included in a housing, and the housing can house components of UE 120, such as processor components and / or memory components. In some aspects, the processor components and the memory components can be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) can be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0029] In general, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a particular RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, an air interface, and / or the like. Frequencies can also be referred to as carriers, frequency channels, and / or the like. Each frequency can support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0030] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly using one or more sidelink channels (e.g., without using base station 110 as an intermediary to communicate with one another). For example, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110. In some aspects, one or more of the base stations 110 can include a gNB or ng-eNB.

[0031] Devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, frequency bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1) (which can span 410 MHz to 7.125 GHz) and / or can communicate using an operating frequency band having a second frequency range (FR2) (which can span 24.25 GHz to 52.6 GHz). Frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a "sub-6 GHz" band. Similarly, FR2 is often referred to as a "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as a "millimeter wave" band by the International Telecommunication Union (ITU). Thus, unless otherwise expressly stated, it should be understood that the term "sub-6 GHz," etc., if used herein, may broadly refer to frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise expressly stated, it should be understood that the term "millimeter wave," etc., if used herein, may broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). It is contemplated that the frequencies included in FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0032] As mentioned above, providing Figure 1 As an example. Other examples may differ from the Figure 1 Examples described.

[0033] Figure 2 is a diagram illustrating an example 200 of a base station 110 communicating with a UE 120 in a wireless network 100 in accordance with various aspects of the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where, in general, T ≥ 1 and R ≥ 1.

[0034] 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 each UE based at least in part on the MCS selected for the UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). A transmit (TX) multiple-input, multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, as needed, and may provide T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modulator 232 may further process the output sample stream (e.g., convert to analog, amplify, filter, and frequency upconvert) to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0035] At UE 120, antennas 252a through 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols as needed, 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 term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a channel quality indicator (CQI) parameter, among other examples. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0036] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0037] The antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include, or may be included within, one or more antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays, among other examples. The antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements. The antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include sets of coplanar antenna elements or sets of non-coplanar antenna elements. The antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. The antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include antenna elements coupled to one or more transmit and / or receive components, such as, Figure 2 One or more antenna elements of one or more components in.

[0038] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from the controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266, if necessary, further processed by the modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station 110. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be configured by a processor (e.g., controller / processor 280) and memory 282 to perform operations described herein (e.g., as described with reference to FIG. Figure 4 and Figure 5 any aspects of any method described).

[0039] At base station 110, uplink signals from UE 120 and other UEs may be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 as needed, and further processed by receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller / processor 240. Base station 110 may include a communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 may include a scheduler 246 to schedule UE 120 for downlink and / or uplink communications. In some aspects, the modulator and demodulator (e.g., MOD / DEMOD 232) of base station 110 may be included in a modem of base station 110. In some aspects, base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. The transceiver may be configured by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., as described with reference to FIG. Figure 4 and Figure 5 any aspects of any method described).

[0040] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or the like may perform one or more techniques associated with obtaining uplink resources for a logical channel without an associated scheduling request configuration, as described in greater detail elsewhere herein. Figure 2 Any other component of the may perform or direct e.g. Figure 5 The operations of process 500 and / or other processes as described herein may be performed. 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 (e.g., code and / or program code) for wireless communications. For example, the one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause the one or more processors, UE 120, and / or base station 110 to perform or direct, for example, Figure 5 The operations of process 500 and / or other processes described herein may be performed. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among other examples.

[0041] In some aspects, the UE includes means for determining that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration; and / or means for transmitting a scheduling request for resources used to transmit data buffered for transmission via the first logical channel via scheduling request resources of a second logical channel that has a valid scheduling request configuration. Means for the UE to perform the operations described herein may include, for example, one or more of the antenna 252, the demodulator 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the modulator 254, the controller / processor 280, or the memory 282.

[0042] In some aspects, the UE includes means for determining not to initiate a random access channel procedure based at least in part on a determination that a second logical channel has a valid scheduling request configuration after determining that data is buffered for transmission via a first logical channel without a valid scheduling request configuration.

[0043] In some aspects, the UE includes means for selecting a second logical channel from one or more logical channels having a valid scheduling request configuration based at least in part on a priority-based selection operation.

[0044] In some aspects, the UE includes means for selecting a second logical channel from one or more logical channels having a valid scheduling request configuration based at least in part on a random selection operation.

[0045] In some aspects, the UE includes means for receiving a resource grant allocating resources for transmission of data buffered for transmission via a first logical channel.

[0046] In some aspects, the UE comprises means for transmitting data via a first logical channel using resources allocated by a resource grant.

[0047] In some aspects, the UE includes means for determining that additional data is buffered for transmission via the second logical channel; and means for transmitting at least a portion of one or more of the data or the additional data using resources allocated by the resource grant.

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

[0049] As pointed out above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0050] Figure 3 3 is a diagram illustrating an example 300 of receiving a resource grant for a logical channel using a random access channel procedure according to various aspects of the present disclosure. Figure 3 As shown, the UE and the base station can communicate via a wireless link (e.g., of an associated wireless network). The UE and the base station can establish one or more logical channels for communicating via the wireless link. For example, the UE and the base station can communicate using one or more logical channels carried on one or more physical channels such as a physical uplink shared channel (PUSCH) and / or a physical downlink shared channel (PDSCH). A first logical channel and a second logical channel in the one or more logical channels can have different resource allocations and / or different resource configurations, as well as other examples.

[0051] The UE may determine that data is buffered for transmission via the logical channel as indicated by reference numeral 305. For example, the UE may determine that the UE has data to transmit via the wireless link to an application server associated with the logical channel.

[0052] As indicated by reference numeral 310, the UE may determine that the logical channel does not have a valid scheduling request (SR) configuration. In other words, the UE may determine that the UE does not have scheduling request resources configured for the logical channel for the UE to indicate that the UE has data buffered for transmission via the logical channel.

[0053] As indicated by reference numeral 315, the UE may initiate a random access channel (RACH) procedure. For example, the UE may initiate the RACH procedure based at least in part on transmitting a first message (e.g., Msg1 or MsgA) to the base station. The UE may transmit the first message using RACH resources that may be shared with one or more additional UEs.

[0054] The UE and the base station may perform a RACH procedure to receive the resource grant, as indicated by reference numeral 320. For example, the UE and the base station may exchange one or more RACH messages as part of a 2-step RACH procedure or a 4-step RACH procedure.

[0055] Based at least in part on the UE initiating and performing a RACH procedure to receive a resource grant allocating resources for the UE to transmit data buffered for transmission via a logical channel, the UE and the base station may consume computing, network, power, and / or communication resources associated with performance of the RACH procedure. Additionally or alternatively, based at least in part on the UE performing the RACH procedure to receive the resource grant, the UE may consume limited RACH resources, which may interfere with another UE attempting to perform a RACH procedure.

[0056] As pointed out above, Figure 3 are provided as examples. Other examples may differ from those described in Figure 3 Examples described.

[0057] In some aspects described herein, a UE may determine that the UE has data to transmit via a first logical channel. The UE may determine that the first logical channel does not have a valid scheduling request configuration for transmitting a scheduling request to request resources for transmitting the data. The UE may determine that a second logical channel (e.g., a channel over which the UE communicates with a base station) has a valid scheduling request configuration (e.g., has valid physical uplink control channel (PUCCH) resources configured for the scheduling request). Based at least in part on the second logical channel having the valid scheduling request configuration, the UE may determine not to initiate a RACH procedure to obtain resources for transmitting the data. Instead, the UE may determine to use scheduling request resources of the second logical channel to transmit a scheduling request for resources for transmitting the data (e.g., to trigger a scheduling request).

[0058] Based at least in part on the UE transmitting a scheduling request for data buffered for transmission via the first logical channel using resources configured for transmitting a scheduling request for the second logical channel, the UE can conserve computational, network, power, and / or communication resources that may have otherwise been used to perform a RACH procedure to obtain resources for transmitting the data. Additionally or alternatively, the UE can conserve network resources allocated for the RACH procedure, which can avoid interfering with another UE attempting to perform a RACH procedure using limited RACH resources. Furthermore, based at least in part on the UE transmitting a scheduling request for data buffered for transmission via the first logical channel using resources configured for transmitting a scheduling request for the second logical channel, the UE can reduce latency associated with the data buffered for transmission via the first logical channel.

[0059] Figure 4 is a diagram illustrating an example 400 associated with obtaining uplink resources for a logical channel without a scheduling request configuration in accordance with various aspects of the present disclosure. Figure 4 As shown, a UE (e.g., UE 120) can communicate with a base station (e.g., base station 110). The UE and base station can be part of a wireless network (e.g., wireless network 100).

[0060] As indicated by reference numeral 405, the base station may send and the UE may receive configuration information. In some aspects, the UE may receive the configuration information from another device (e.g., from another base station, a TRP associated with the base station, and / or another UE, among other examples) and / or a communication standard, among other examples. In some aspects, the UE may receive the configuration information via one or more of radio resource control (RRC) signaling or medium access control control element (MAC-CE) signaling, and / or the UE may determine the configuration information from a communication standard, among other examples. In some aspects, the configuration information may include an indication of one or more configuration parameters for selection by the UE (e.g., that the UE already knows), explicit configuration information for the UE to use to configure the UE, and / or the like.

[0061] In some aspects, the configuration information may indicate that the UE is to communicate with the base station via one or more physical channels (e.g., PUSCH, PUCCH, PDSCH, and / or Physical Downlink Control Channel (PDCCH), among other examples). In some aspects, the configuration information may indicate that the UE is to communicate with the base station via one or more logical channels carried by or within the one or more physical channels. For example, the configuration information may indicate that the UE is to communicate via a first logical channel using a first set of resources of the physical channel and to communicate via a second logical channel using a second set of resources of the physical channel.

[0062] In some aspects, the configuration information may instruct the UE to determine whether the second logical channel has a valid scheduling request configuration based at least in part on determining that data is buffered for transmission via the first logical channel that does not have a valid scheduling request. In some aspects, the configuration information may instruct the UE to determine not to initiate a RACH procedure based at least in part on determining that the second logical channel has a valid scheduling request configuration. In some aspects, the configuration information may instruct the UE to select the second logical channel from one or more logical channels with a valid scheduling request configuration based at least in part on, for example, a priority-based selection operation or a random selection operation, among other examples.

[0063] In some aspects, the configuration information may indicate that the UE is to transmit a scheduling request via scheduling request resources of the second logical channel (e.g., via PUCCH resources). In some aspects, the configuration information may indicate that the UE is to receive a resource grant allocating resources for transmitting data, and the UE is to transmit at least a portion of the data via the first logical channel using the allocated resources.

[0064] As indicated by reference numeral 410, the UE may configure the UE to communicate with the base station. In some aspects, the UE may configure the UE based at least in part on the configuration information. In some aspects, the UE may be configured to perform one or more operations described herein.

[0065] As shown by reference numeral 415, the UE and the base station can communicate via multiple logical channels. In some aspects, the base station can configure multiple logical channels using one or more physical channels to operate. In some aspects, the base station can configure one or more logical channels with valid scheduling request configurations among the multiple logical channels and / or one or more other logical channels without valid scheduling request configurations among the multiple logical channels. In some aspects, the base station can configure different priorities for the multiple channels. The multiple channels can be associated with a logical channel identifier (LCID).

[0066] As indicated by reference numeral 420, the UE may determine that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration (e.g., does not have valid scheduling request resources). In some aspects, the UE may trigger a scheduling request based at least in part on the data being buffered for transmission via the first logical channel. The UE may determine that the first logical channel does not have a valid scheduling request configuration (e.g., the first logical channel does not have valid PUCCH resources configured for a scheduling request).

[0067] As indicated by reference numeral 425, the UE may determine that one or more additional logical channels have one or more valid scheduling request configurations. For example, the UE may determine that the second logical channel and / or the one or more additional logical channels have valid scheduling request configurations. The scheduling request configuration may include a configuration of resources for the UE to send and the base station to receive scheduling requests. For example, the second logical channel may have resources allocated within a PUCCH for the UE to indicate that the UE has data buffered for transmission to the base station.

[0068] As indicated by reference numeral 430, the UE may determine not to initiate a RACH procedure. For example, the UE may determine not to initiate a RACH procedure based at least in part on a determination that an additional logical channel (e.g., a second logical channel) has a valid scheduling request configuration. The UE may determine that the UE may send a scheduling request via a scheduling request resource of the second logical channel instead of initiating a RACH procedure.

[0069] As indicated by reference numeral 435, the UE may select a second logical channel having a valid scheduling request configuration to send the scheduling request. For example, the UE may select the second logical channel from a set of logical channels having a valid scheduling request configuration, and the UE may use the second logical channel to send the scheduling request (e.g., via the scheduling request resources of the second logical channel). In some aspects, the UE may select the second logical channel based at least in part on a priority-based selection operation. For example, the UE may select the second logical channel based at least in part on a second logical channel having the highest priority or the lowest priority in the set of logical channels having a valid scheduling request configuration. In some aspects, the UE may select the second logical channel from the set of logical channels having a valid scheduling request configuration based at least in part on a random (e.g., pseudo-random) selection operation.

[0070] As indicated by reference numeral 440, the UE may send, and the base station may receive, a scheduling request via the scheduling request resources of the second logical channel. In some aspects, the UE may send the scheduling request via a PUCCH associated with a valid scheduling request configuration for the second logical channel. In other words, the UE may trigger a scheduling request using the scheduling request resources of the second logical channel.

[0071] As indicated by reference numeral 445, the base station may determine resources to allocate to the UE (e.g., for transmission of data buffered for transmission via the first logical channel). In some aspects, the base station may determine that the UE has data buffered for transmission. In some aspects, the base station may not be aware of the logical channel associated with the data buffered for transmission. In some aspects, the base station may determine to allocate resources of the PUSCH to the UE for transmission of the data.

[0072] As indicated by reference numeral 450, the UE may receive and the base station may send a resource grant. In some aspects, the resource grant may allocate resources for transmitting data buffered for transmission via the first logical channel. For example, the resource grant may allocate resources for one or more uplink transmissions, and the UE may determine to use the allocated resources to transmit data buffered for transmission via the first logical channel.

[0073] As indicated by reference numeral 455, the UE may send data and the base station may receive data. For example, the UE may transmit data that is buffered for transmission via the first logical channel. In some aspects, the UE may determine that additional data is buffered for transmission via the second logical channel. In other words, the UE may determine that it has first data buffered for transmission via the first logical channel and second data buffered for transmission via the second logical channel. In some aspects, the UE may use resources allocated by the resource grant to transmit at least a portion of the data buffered for transmission via the first logical channel. In some aspects, the UE may use resources allocated by the resource grant to transmit at least a portion of the data buffered for transmission via the second logical channel. In some aspects, the UE may transmit data and indicate (e.g., using a buffer status report (BSR)) that the UE has additional data to transmit. The base station may transmit one or more additional resource grants for the UE to use to transmit the first data and the second data.

[0074] Based at least in part on the UE transmitting the scheduling request for data buffered for transmission via the first logical channel using resources configured for transmitting the scheduling request for the second logical channel, the UE can conserve computational, network, power, and / or communication resources that may have otherwise been used to perform a RACH procedure to obtain resources for transmitting the data. Additionally or alternatively, the UE can conserve network resources allocated for the RACH procedure, which can avoid interfering with another UE attempting to perform a RACH procedure using limited RACH resources. Furthermore, based at least in part on the UE transmitting the scheduling request for data buffered for transmission via the first logical channel using resources configured for transmitting the scheduling request for the second logical channel, the UE can reduce latency associated with the data buffered for transmission via the first logical channel (e.g., compared to the RACH procedure).

[0075] As pointed out above, Figure 4 are provided as examples. Other examples may differ from those described in Figure 4 Examples described.

[0076] Figure 5is a diagram illustrating an example process 500, performed, for example, by a UE, in accordance with various aspects of the present disclosure. Example process 500 is an example in which a UE (eg, UE 120) performs operations associated with obtaining uplink resources for a logical channel without an associated scheduling request configuration.

[0077] like Figure 5 As shown in , in some aspects, process 500 may include determining that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration (block 510). For example, as described above, a UE (e.g., using Figure 6 The determining component 608 depicted in FIG. 4 may determine that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration.

[0078] like Figure 5 As further shown in FIG. 5 , in some aspects, process 500 may include transmitting, via a scheduling request resource of a second logical channel having a valid scheduling request configuration, a scheduling request for resources used to transmit data buffered for transmission via the first logical channel (block 520). For example, as described above, a UE (e.g., using Figure 6 The transmitting component 604 depicted in FIG may transmit, via a scheduling request resource of a second logical channel having a valid scheduling request configuration, a scheduling request for resources used to transmit data buffered for use via the first logical channel.

[0082] In a third aspect, alone or in combination with one or more of the first and second aspects, process 500 includes selecting a second logical channel from one or more logical channels having a valid scheduling request configuration based at least in part on a random selection operation.

[0083] In a fourth aspect, alone or in combination with one or more of the first to third aspects, process 500 includes receiving a resource grant allocating resources for transmitting data buffered for transmission via a first logical channel.

[0084] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, process 500 includes transmitting data via a first logical channel using resources allocated by a resource grant.

[0085] In a sixth aspect, alone or in combination with one or more of aspects 1 to 5, process 500 includes determining that additional data is buffered for transmission via a second logical channel, and transmitting at least a portion of one or more of the data or additional data using resources allocated by the resource grant.

[0086] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, transmitting the scheduling request comprises transmitting the scheduling request via a physical uplink control channel associated with a valid scheduling request configuration of the second logical channel.

[0087] although Figure 5 Example blocks of process 500 are shown, but in some aspects, process 500 may include Figure 5 Additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in process 500 may be used. Additionally or alternatively, two or more blocks in process 500 may be executed in parallel.
