Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that one or more symbols, scheduled for transmitting to a base station or receiving from the base station, conflict with a measurement gap. The UE may transmit a random access preamble based at least in part on determining the conflict. In some aspects, the UE may receive, from a physical layer of the UE, an indication that the one or more symbols were not used for transmission or reception, such that the conflict is determined based at least in part on the indication. As an alternative, the UE may refrain from instructing a physical layer of the UE to use the one or more symbols for transmission or reception, based at least in part on determining the conflict. Numerous other aspects are described.

Description

AVOIDING COLLISIONS WITH MEASUREMENT GAPS

FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for avoiding collisions with measurement gaps.

BACKGROUND

Wireless communication systems are widely deployed to provide various 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, or the like) . 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) .

A wireless network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs) . A UE may communicate with a BS via the downlink and uplink. “Downlink” (or forward link) refers to the communication link from the BS to the UE, and “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, a gNB, an access point (AP) , a radio head, a transmit receive point (TRP) , a New Radio (NR) BS, a 5G Node B, or the like.

The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a municipal, national, regional, and even global level. NR, which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL) , using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM) ) on the uplink (UL) , as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

DETAILED DESCRIPTION

Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein, one skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses 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, or the like (collectively referred to as “elements” ) . These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

It should be noted that while aspects may be described herein using terminology commonly associated with a 5G or NR radio access technology (RAT) , aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G) .

Fig. 1 is a diagram illustrating an example of a wireless network 100, in accordance with 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 user equipment (UEs) and may also be referred to as an NR BS, a Node B, a gNB, a 5G node B (NB) , an access point, a transmit receive point (TRP) , or the like. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and/or a BS subsystem serving this coverage area, depending on the context in which the term is used.

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

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

Wireless network 100 may 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 may also be a UE that can relay transmissions for other UEs. In the example shown in Fig. 1, a relay BS 110d may communicate with macro BS 110a and a UE 120d in order to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.

Wireless network 100 may 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 may have different transmit power levels, different coverage areas, and different impacts on interference in wireless network 100. For example, macro BSs may have a high transmit power level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts) .

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

UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, or the like. A UE may 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, biometric sensors/devices, wearable devices (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, smart meters/sensors, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, and/or location tags, that may communicate with a base station, another device (e.g., remote device) , or some other entity. A wireless node may 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 may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband internet of things) devices. Some UEs may be considered a Customer Premises Equipment (CPE) . UE 120 may be included inside a housing that houses components of UE 120, such as processor components and/or memory components. In some aspects, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.

In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, or the like. A frequency may also be referred to as a carrier, a frequency channel, or the like. Each frequency may 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 may be deployed.

In some aspects, and as described below in connection with Fig. 3, a UE (e.g., UE 120a) may be connected with a secondary cell group (SCG) that includes at least one base station (e.g., base station 110a) for data channels and a master cell group (MCG) that includes at least one additional base station for control channels. Accordingly, the UE 120a may be configured to perform measurements (e.g., periodic or event-based) of at least one reference signal (e.g., synchronization signal blocks (SSBs) , channel state information reference signals (CSI-RSs) , and/or another reference signal) on the MCG. Additionally, the UE 120a may be configured for receiving from the SCG (e.g., periodic measurements of at least one reference signal, periodic receptions over a physical downlink shared channel (PDSCH) configured via semi-persistent scheduling (SPS) , aperiodic or semi-periodic measurements, and/or receptions over a PDSCH configured via dynamic grant) and/or transmitting to the SCG (e.g., periodic windows for transmitting scheduling requests (SRs) , periodic transmissions of at least one reference signal, such as a sounding reference signal (SRS) , periodic transmissions on a physical uplink shared channel (PUSCH) associated with a configured grant, aperiodic or semi-periodic reference signal transmissions, and/or transmissions on a PDSCH configured via dynamic grant) .

When the MCG and the SCG do not coordinate (e.g., via a backhaul connection) and/or a large quantity of UEs present within the MCG prevent the MCG from optimizing scheduled measurement gaps (e.g., for the measurements described above) , a window associated with a downlink reception from or an uplink transmission to the SCG may conflict with a measurement gap for the MCG. As used herein, “conflict” may refer to at least a partial overlap in time such that a UE is unable to use both the first configuration and the second configuration. A conflict may be temporary (e.g., when the first configuration and the second configuration are associated with different periodicities, when the first configuration is event-based, and/or when the second configuration is event-based) or may persist (e.g., when the first configuration and the second configuration are associated with a same periodicity or with periodicities that are multiples of each other) .

Accordingly, as shown in Fig. 1 and described elsewhere herein, the UE 120a may reduce or skip a measurement gap (e.g., at a PHY layer of the UE 120a) in order to perform a downlink reception or an uplink transmission, may initiate a random access channel (RACH) procedure (e.g., at a MAC layer of the UE 120a) in order to obtain a new measurement gap or a new configuration for downlink/uplink, or may reject a configuration indicating the measurement gap or a configuration indicating the downlink/uplink (e.g., at an RRC layer of the UE 120a) based at least in part on the conflict.

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

Devices of wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided based on frequency or wavelength into various classes, bands, channels, or the like. For example, devices of wireless network 100 may communicate using an operating band having a first frequency range (FR1) , which may span from 410 MHz to 7.125 GHz, and/or may communicate using an operating band having a second frequency range (FR2) , which may span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a “sub-6 GHz” band. Similarly, FR2 is often referred to as a “millimeter wave” band despite being different from the extremely high frequency (EHF) band (30 GHz –300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. Thus, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies less than 6 GHz, frequencies within FR1, and/or mid-band frequencies (e.g., greater than 7.125 GHz) . Similarly, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent 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 techniques described herein are applicable to those modified frequency ranges.

As indicated above, Fig. 1 is provided as an example. Other examples may differ from what is described with regard to Fig. 1.

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

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

At UE 120, antennas 252a through 252r may receive the 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) a 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 if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller/processor 280. The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some aspects, one or more components of UE 120 may be included in a housing 284.

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

Antennas (e.g., antennas 234a through 234t and/or antennas 252a through 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. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include a set of coplanar antenna elements and/or a set of non-coplanar antenna elements. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include antenna elements within a single housing and/or antenna elements within multiple housings. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of Fig. 2.

On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from controller/processor 280. Transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM or CP-OFDM) , and transmitted to base station 110. In some aspects, a modulator and a 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 detector 256, receive processor 258, transmit processor 264, and/or 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, with reference to Figs. 5-10) .

At base station 110, the uplink signals from UE 120 and other UEs may be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a 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 communication unit 244 and communicate to network controller 130 via communication unit 244. Base station 110 may include a scheduler 246 to schedule UEs 120 for downlink and/or uplink communications. In some aspects, a modulator and a demodulator (e.g., MOD/DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna (s) 234, modulators and/or demodulators 232, MIMO detector 236, receive processor 238, transmit processor 220, and/or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller/processor 240) and memory 242 to perform aspects of any of the methods described herein (for example, with reference to Figs. 5-10) .

Controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component (s) of Fig. 2 may perform one or more techniques associated with avoiding collisions with measurement gaps, as described in more detail elsewhere herein. For example, controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component (s) of Fig. 2 may perform or direct operations of, for example, process 800 of Fig. 8, process 900 of Fig. 9, process 1000 of Fig. 10, and/or other processes as described herein.

Memories

242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and/or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station 110 and/or the UE 120, may cause the one or more processors, the UE 120, and/or the base station 110 to perform or direct operations of, for example, process 800 of Fig. 8, process 900 of Fig. 9, process 1000 of Fig. 10, and/or other processes as described herein. In some aspects, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples.

In some aspects, a UE (e.g., the UE 120 and/or apparatus 1100 of Fig. 11) may include means for determining that one or more symbols, scheduled for transmitting to a base station (e.g., the base station 110 and/or apparatus 1200 of Fig. 12) or receiving from the base station, conflict with a measurement gap; and/or means for transmitting a random access preamble based at least in part on determining the conflict. The means for the UE to perform operations described herein may include, for example, one or more of antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, modulator 254, controller/processor 280, or memory 282.

Additionally, or alternatively, a UE (e.g., the UE 120 and/or apparatus 1100 of Fig. 11) may include means for determining that one or more symbols, scheduled for transmitting to a base station (e.g., the base station 110 and/or apparatus 1200 of Fig. 12) or receiving from the base station, conflict with a measurement gap; and/or means for transmitting to the base station, or means for receiving from the base station, by refraining from measuring during a current measurement gap or a next measurement gap, based at least in part on determining the conflict. The means for the UE to perform operations described herein may include, for example, one or more of antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, modulator 254, controller/processor 280, or memory 282.

Additionally, or alternatively, a UE (e.g., the UE 120 and/or apparatus 1100 of Fig. 11) may include means for receiving a first configuration associated with a measurement gap and a second configuration associated with scheduling for transmitting to a base station (e.g., the base station 110 and/or apparatus 1200 of Fig. 12) or receiving from the base station; and/or means for transmitting a rejection of the first configuration or a rejection of the second configuration based at least in part on determining a conflict between the first configuration and the second configuration. The means for the UE to perform operations described herein may include, for example, one or more of antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, modulator 254, controller/processor 280, or memory 282.

While blocks in Fig. 2 are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and/or the TX MIMO processor 266 may be performed by or under the control of controller/processor 280.

As indicated above, Fig. 2 is provided as an example. Other examples may differ from what is described with regard to Fig. 2.

Fig. 3 is a diagram illustrating an example 300 of dual connectivity, in accordance with the present disclosure. The example shown in Fig. 3 is for an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) -NR dual connectivity (EN-DC) mode. In the EN-DC mode, a UE 120 communicates using an LTE RAT on an MCG, and the UE 120 communicates using an NR RAT on an SCG. As used herein, “secondary cell group” or “SCG” may include at least a primary cell (PCell) that manages a control plane for the UE 120. In some aspects, the PCell may also manage a data plane for the UE 120 (e.g., in combination with or as a backup to the data plane managed by the PSCell) . As used herein, “master cell group” or “MCG” may include at least one secondary cell (SCell) , such as a primary secondary cell (PSCell) , that manages a data plane for the UE 120. The UE 120 may be configured for carrier aggregation with the secondary cell and the primary cell.

However, aspects described herein may apply to an EN-DC mode (e.g., where the MCG is associated with an LTE RAT and the SCG is associated with an NR RAT) , an NR-E-UTRA dual connectivity (NE-DC) mode (e.g., where the MCG is associated with an NR RAT and the SCG is associated with an LTE RAT) , an NR dual connectivity (NR-DC) mode (e.g., where the MCG is associated with an NR RAT and the SCG is also associated with the NR RAT) , or another dual connectivity mode (e.g., where the MCG is associated with a first RAT and the SCG is associated with one of the first RAT or a second RAT) . The EN-DC mode is sometimes referred to as an NR or 5G non-standalone (NSA) mode. Thus, as used herein, “dual connectivity mode” may refer to an EN-DC mode, an NE-DC mode, an NR-DC mode, and/or another type of dual connectivity mode.

As shown in Fig. 3, a UE 120 may communicate with both an eNB 305 (e.g., a 4G base station 110) and a gNB 310 (e.g., a 5G base station 110) , and the eNB 305 and the gNB 310 may communicate (e.g., directly or indirectly) with a 4G/LTE core network, shown as an evolved packet core (EPC) that includes a mobility management entity (MME) , a packet data network gateway (PGW) , a serving gateway (SGW) , and/or other devices. In Fig. 3, the PGW and the SGW are shown collectively as P/SGW. In some aspects, the eNB 305 and the gNB 310 may be co-located at the same base station 110. In some aspects, the eNB 305 and the gNB 310 may be included in different base stations 110 (e.g., may not be co-located) .

As further shown in Fig. 3, in some aspects, a wireless network that permits operation in a 5G NSA mode may permit such operations using an MCG for a first RAT (e.g., an LTE RAT or a 4G RAT) and an SCG for a second RAT (e.g., an NR RAT or a 5G RAT) . In this case, the UE 120 may communicate with the eNB 305 via the MCG, and may communicate with the gNB 310 via the SCG. In some aspects, the MCG may anchor a network connection between the UE 120 and the 4G/LTE core network (e.g., for mobility, coverage, and/or control plane information) , and the SCG may be added as additional carriers to increase throughput (e.g., for data traffic and/or user plane information) . In some aspects, the gNB 310 and the eNB 305 may not transfer user plane information between one another. In some aspects, a UE 120 operating in a dual connectivity mode may be concurrently connected with an LTE base station 110 (e.g., an eNB) and an NR base station 110 (e.g., a gNB) (e.g., in the case of EN-DC or NE-DC) , or may be concurrently connected with one or more base stations 110 that use the same RAT (e.g., in the case of NR-DC) . In some aspects, the MCG may be associated with a first frequency band (e.g., a sub-6 GHz band and/or an FR1 band) and the SCG may be associated with a second frequency band (e.g., a millimeter wave band and/or an FR2 band) .

The UE 120 may communicate via the MCG and the SCG using one or more radio bearers (e.g., data radio bearers (DRBs) and/or signaling radio bearers (SRBs) ) . For example, the UE 120 may transmit or receive data via the MCG and/or the SCG using one or more DRBs. Similarly, the UE 120 may transmit or receive control information (e.g., RRC information and/or measurement reports) using one or more SRBs. In some aspects, a radio bearer may be dedicated to a specific cell group (e.g., a radio bearer may be an MCG bearer or an SCG bearer) . In some aspects, a radio bearer may be a split radio bearer. A split radio bearer may be split in the uplink and/or in the downlink. For example, a DRB may be split on the downlink (e.g., the UE 120 may receive downlink information for the MCG or the SCG in the DRB) but not on the uplink (e.g., the uplink may be non-split with a primary path to the MCG or the SCG, such that the UE 120 transmits in the uplink only on the primary path) . In some aspects, a DRB may be split on the uplink with a primary path to the MCG or the SCG. A DRB that is split in the uplink may transmit data using the primary path until a size of an uplink transmit buffer satisfies an uplink data split threshold. If the uplink transmit buffer satisfies the uplink data split threshold, the UE 120 may transmit data to the MCG or the SCG using the DRB.

In some aspects, and as shown in Fig. 3, the UE 120 may receive a first configuration associated with a measurement gap (e.g., for performing measurements of at least one reference signal, such as an SSB, a CSI-RSs, and/or another reference signal) for the eNB 305. Additionally, the UE 120 may receive a second configuration associated with scheduling for transmitting to the gNB 310 (e.g., periodic windows for transmitting SRs, periodic transmissions of at least one reference signal, such as an SRS, periodic transmissions on a PUSCH associated with a configured grant, aperiodic or semi-periodic reference signal transmissions, and/or transmissions on a PDSCH configured via dynamic grant) or receiving from the gNB 310 (e.g., periodic measurements of at least one reference signal, periodic receptions over a PDSCH configured via SPS, aperiodic or semi-periodic measurements, and/or receptions over a PDSCH configured via dynamic grant) .

As indicated above, Fig. 3 is provided as an example. Other examples may differ from what is described with respect to Fig. 3.

Fig. 4 is a diagram illustrating an example 400 of measurement gap collision, in accordance with the present disclosure. As shown in Fig. 4, a UE may be dual connected (e.g., as described above in connection with Fig. 3) with at least two base stations. In example 400, the UE is dual connected with a gNB associated with a 5G network and an eNB associated with a legacy network (e.g., an LTE network or a 3G network) . Although described below using the gNB and the eNB, the description similarly applies to other dual connectivity configurations.

As shown by reference number 405, the UE may receive, from the gNB, a configuration associated with an uplink to the gNB (e.g., periodic windows for transmitting SRs, periodic transmissions of at least one reference signal, such as an SRS, periodic transmissions on a PUSCH associated with a configured grant, aperiodic or semi-periodic reference signal transmissions, and/or transmissions on a PDSCH configured via dynamic grant) or a downlink from the gNB (e.g., periodic measurements of at least one reference signal, periodic receptions over a PDSCH configured via SPS, aperiodic or semi-periodic measurements, and/or receptions over a PDSCH configured via dynamic grant) .

As shown by reference number 410, the UE may receive, from the eNB, a configuration associated with a measurement gap (e.g., for performing measurements of at least one reference signal, such as an SSB, a CSI-RS, and/or another reference signal) for the eNB. The measurement gap may be periodic or may be event-based.

Accordingly, as shown by reference number 415, the UE may perform measurements within the measurement gap and transmit a report, generated based at least in part on the measurements, to the eNB.

The UE may also have data to transmit on the uplink to the gNB or be scheduled to receive data on the downlink from the gNB. However, in some situations, the configuration for the eNB and the configuration for the gNB may conflict. For example, an operator of a 5G network including the gNB and an operator of the legacy network including the eNB may not coordinate (e.g., on a backhaul connection) such that the configurations conflict.

Additionally, or alternatively, a large quantity of UEs may be present and/or mobile within a cell including the eNB. Accordingly, the eNB may be unable to optimize measurement gaps for each UE such that some UEs are configured for measurements gaps that conflict with windows for transmissions to or reception from the gNB.

Additionally, or alternatively, at least one of the eNB or the gNB may be part of a non-terrestrial network. For example, the eNB and/or the gNB may include a satellite that is mobile relative to the UE. The mobility of base stations within a non-terrestrial networks may be high (e.g., the eNB and/or the gNB may only have minutes of contact with the UE before handover to another mobile eNB and/or gNB, respectively) . Accordingly, the eNB may be unable to optimize the measurement gaps for the UE before handover to another eNB. Additionally, or alternatively, the eNB may be unable to optimize the measurement gaps for the UE because the UE will undergo handover between gNBs relatively quickly.

Accordingly, as shown by reference number 420, the UE may be unable to transmit or receive using the configuration for the gNB due to the UE performing measurements within the measurement gap configured by the eNB. Moreover, as shown in Fig. 4, this conflict may persist when the configuration for the gNB and the configuration for the eNB are associated with a same periodicity or when one of the configurations is associated with a periodicity that is a multiple of a periodicity associated with the other of the configurations.

Accordingly, as shown by reference number 425, the UE may again perform measurements within the measurement gap and transmit a report, generated based at least in part on the measurements, to the eNB. Due to the conflict being persistent, and as shown by reference number 430, the UE may again be unable to transmit or receive using the configuration for the gNB due to the UE performing measurements within the measurement gap configured by the eNB.

Persistent conflicts like those described above can cause long latencies. For example, SR configurations may include a maximum quantity of retransmissions up to 64 and a maximum amount of time between SR attempts up to 128 milliseconds (ms) such that a persistent conflict can waste up to 8192 ms of time without the UE transmitting the SR. Similar latencies can happen for other uplink transmissions or for downlink transmissions, such as configured grants. These latencies cause the UE and the gNB to waste processing resources and power. Additionally, network resources reserved for use by the UE and the gNB are wasted because the UE is unable to transmit or receive during the measurement gaps.

Some techniques and apparatuses described herein enable a UE (e.g., UE 120) to resolve conflicts between a first configuration associated with a measurement gap (e.g., for an eNB) and a second configuration associated with scheduling for transmitting or receiving (e.g., with a gNB) . As a result, the UE 120 may reduce latency caused by conflicts between measurement gaps and time windows for transmission or reception. The UE 120 thus conserves processing resources and power and more efficiently uses network resources reserved for use by the UE on an uplink and/or a downlink.

In some aspects, an RRC layer of the UE 120 may reject the first configuration and/or the second configuration. Accordingly, the UE 120 may receive a new configuration associated with a measurement gap (e.g., for the eNB) or a new configuration associated with scheduling for transmitting or receiving (e.g., with the gNB) , respectively. Thus, the UE 120 pre-emptively avoids suffering latency and wasting processing resources, network overhead, and power due to the conflict between the first configuration and the second configuration.

Additionally, or alternatively, a MAC layer of the UE 120 may switch logical channels when transmitting to or receiving from the gNB in order to avoid the conflict. Thus, the UE 120 reduces latency that would otherwise occur, and conserves processing resources, network overhead, and power that would otherwise be consumed, due to the conflict between the first configuration and the second configuration. Additionally, or alternatively, the MAC layer of the UE 120 may initiate a RACH procedure with the gNB (e.g., by transmitting a random access preamble to the gNB) based at least in part on the conflict. Accordingly, the UE 120 may receive a new configuration associated with scheduling for transmitting or receiving (e.g., with the gNB) . As a result, the UE 120 reduces latency that would otherwise occur, and conserves processing resources, network overhead, and power that would otherwise be consumed, due to the conflict between the first configuration and the second configuration.

Additionally, or alternatively, a PHY layer of the UE 120 may skip or exit a current measurement gap in order to perform a transmission or reception (e.g., with the gNB) . As an alternative, the PHY layer of the UE 120 may skip a next measurement gap in order to perform the transmission or reception. As a result, the UE 120 reduces latency that would otherwise occur, and conserves processing resources, network overhead, and power that would otherwise be consumed, due to the conflict between the first configuration and the second configuration.

As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with respect to Fig. 4.

Fig. 5 is a diagram illustrating an example 500 associated with avoiding collisions with measurement gaps at an RRC layer, in accordance with the present disclosure. As shown in Fig. 5, a UE 120 may be dual connected (e.g., as described above in connection with Fig. 3) with at least two base stations. In example 500, the UE 120 is dual connected with a gNB 310 associated with a 5G network and an eNB 305 associated with a legacy network (e.g., an LTE network or a 3G network) . Although described below using the gNB and the eNB, the description similarly applies to other dual connectivity configurations. For example, the UE 120 may be dual connected with two different 5G networks. Additionally, or alternatively, although described below as terrestrial, the description similarly applies to the gNB, the eNB, and/or another base station connected to the UE 120 being non-terrestrial (e.g., satellite-based) .

As shown in connection with reference number 505, the gNB 310 may transmit, and the UE 120 may receive, a configuration associated with scheduling for transmitting to the gNB 310 or receiving from the gNB 310. In some aspects, the configuration may be associated with an SR from the UE 120 to the gNB 310. For example, the configuration may include a SchedulingRequestConfig data structure, as defined in 3GPP specifications and/or another standard. Accordingly, the configuration may indicate one or more resources (e.g., one or more frequency resources, one or more time resources, one or more spatial resources, and/or other resources) to use for the UE 120 to transmit an SR to the gNB 310. For example, the configuration may include an sr-PUCCH-ResourceIndex data structure, an sr-ConfigIndex data structure, and/or another similar data structure indicating the one or more resources, as defined in 3GPP specifications and/or another standard.

Additionally, or alternatively, the configuration may be associated with a PUSCH from the UE 120 to the gNB 310. For example, the configuration may include a PUSCH-Config data structure, a ConfiguredGrantConfig data structure, and/or another similar data structure, as defined in 3GPP specifications and/or another standard. Accordingly, the configuration may indicate one or more resources (e.g., one or more frequency resources, one or more time resources, one or more spatial resources, and/or other resources) to use for the UE 120 to transmit data to the gNB 310 on the PUSCH. For example, the configuration may include a pusch-TimeDomainAllocationList data structure, a resourceAllocation data structure, and/or another similar data structure indicating the one or more resources, as defined in 3GPP specifications and/or another standard.

Additionally, or alternatively, the configuration may be associated with another transmission from the UE 120 to the gNB 310. For example, the configuration may include a PUCCH-ConfigCommon data structure, a PUCCH-ConfigDedicated data structure, an SRS-Config, and/or another similar data structure, as defined in 3GPP specifications and/or another standard. Accordingly, the configuration may indicate one or more resources to use for the UE 120 to transmit reference signals, data, and/or control information to the gNB 310. For example, the configuration may include a PUCCH-ResourceSet data structure, an SRS-Resource data structure, and/or another similar data structure indicating the one or more resources, as defined in 3GPP specifications and/or another standard.

In some aspects, the configuration may be associated with an SSB, a CSI-RS, and/or another reference signal to the UE 120 from the gNB 310. For example, the configuration may include a ServingCellConfigCommonSIB data structure, a CSI-ReportConfig data structure, and/or another similar data structure, as defined in 3GPP specifications and/or another standard. Accordingly, the configuration may indicate one or more resources (e.g., one or more frequency resources, one or more time resources, one or more spatial resources, and/or other resources) to use for the UE 120 to measure the reference signal from the gNB 310. For example, the configuration may include a CSI-ResourceConfig data structure, an sr-ConfigIndex data structure, and/or another similar data structure indicating the one or more resources, as defined in 3GPP specifications and/or another standard.

Additionally, or alternatively, the configuration may be associated with a PDSCH to the UE 120 from the gNB 310. For example, the configuration may include a PDSCH-Config data structure, an SPS-Config data structure, and/or another similar data structure, as defined in 3GPP specifications and/or another standard. Accordingly, the configuration may indicate one or more resources (e.g., one or more frequency resources, one or more time resources, one or more spatial resources, and/or other resources) to use for the UE 120 to receive data from the gNB 310 on the PDSCH. For example, the configuration may include a pdsch-AllocationList data structure, a resourceAllocation data structure, and/or another similar data structure indicating the one or more resources, as defined in 3GPP specifications and/or another standard.

Additionally, or alternatively, the configuration may be associated with another transmission to the UE 120 from the gNB 310. For example, the configuration may include a PDCCH-ConfigCommon data structure, a PDCCH-Config data structure, and/or another similar data structure, as defined in 3GPP specifications and/or another standard. Accordingly, the configuration may indicate one or more resources to use for the UE 120 to receive reference signals, data, and/or control information from the gNB 310. For example, the configuration may include a ControlResourceSet data structure, a SearchSpace data structure, and/or another similar data structure indicating the one or more resources, as defined in 3GPP specifications and/or another standard.

As shown in connection with reference number 510, the eNB 305 may transmit, and the UE 120 may receive, a configuration associated with a measurement gap. For example, the configuration may include a MeasGapConfig data structure, as defined in 3GPP specifications and/or another standard. In some aspects, the measurement gap may be event-based. As an alternative, the measurement gap may be periodic. Accordingly, the configuration may indicate one or more resources, that repeat according to a period, to use for the UE 120 to measure one or more reference signals from the gNB 310.

As shown in connection with reference number 515, the UE 120 may determine a conflict between the configurations. For example, as shown in Fig. 5, the RRC layer of the UE 120 may determine the conflict based at least in part on one or more symbols associated with the configuration from the gNB 310 overlapping (e.g., at least partially in time) with the measurement gap.

Accordingly, as shown in connection with reference number 520a, the UE 120 may transmit, and the gNB 310 may receive, a rejection of the configuration associated with scheduling for transmitting to the gNB 310 or receiving from the gNB 310. In some aspects, the UE 120 may indicate the conflict to the gNB 310 (e.g., in an RRC message) with the rejection. As shown in connection with reference number 525a, the gNB 310 may transmit, and the UE 120 may receive, a new configuration associated with scheduling for transmitting to the gNB 310 or receiving from the gNB 310, based at least in part on the rejection. Accordingly, the UE 120 pre-emptively avoids suffering latency and wasting processing resources, network overhead, and power due to the conflict between the configurations by obtaining the new configuration from the gNB 310.

As an alternative, and as shown in connection with reference number 520b, the UE 120 may transmit, and the eNB 305 may receive, a rejection of the configuration associated with the measurement gap. In some aspects, the UE 120 may indicate the conflict to the eNB 305 (e.g., in an RRC message) with the rejection. As shown in connection with reference number 525b, the eNB 305 may transmit, and the UE 120 may receive, a new configuration associated with a measurement gap, based at least in part on the rejection. Accordingly, the UE 120 pre-emptively avoids suffering latency and wasting processing resources, network overhead, and power due to the conflict between the configurations by obtaining the new configuration from the eNB 305.

By using techniques as described in connection with Fig. 5, the RRC layer of the UE 120 rejects the configuration from the eNB 305 and/or the configuration from the gNB 310. Accordingly, the UE 120 receives a new configuration associated with a measurement gap (e.g., for the eNB 305) or a new configuration associated with scheduling for transmitting or receiving (e.g., with the gNB 310) , respectively. Thus, the UE 120 pre-emptively avoids suffering latency and wasting processing resources, network overhead, and power due to the conflict between the configurations.

As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with respect to Fig. 5.

Fig. 6A is a diagram illustrating an example 600 associated with avoiding collisions with measurement gaps at a MAC layer, in accordance with the present disclosure. As shown in Fig. 6A, a UE 120 may be dual connected (e.g., as described above in connection with Fig. 3) with at least two base stations. In example 600, the UE 120 is dual connected with a gNB 310 associated with a 5G network and an eNB 305 associated with a legacy network (e.g., an LTE network or a 3G network) . Although described below using the gNB and the eNB, the description similarly applies to other dual connectivity configurations. For example, the UE 120 may be dual connected with two different 5G networks. Additionally, or alternatively, although described below as terrestrial, the description similarly applies to the gNB, the eNB, and/or another base station connected to the UE 120 being non-terrestrial (e.g., satellite-based) .

As shown in connection with reference number 605, the gNB 310 may transmit, and the UE 120 may receive, a configuration associated with scheduling for transmitting to the gNB 310 or receiving from the gNB 310. For example, an RRC layer of the UE 120 may receive the configuration from the gNB 310 as described above in connection with reference number 505 of Fig. 5. As further shown in Fig. 6A, the RRC layer may pass the configuration to the MAC layer of the UE 120.

As shown in connection with reference number 610, the eNB 305 may transmit, and the UE 120 may receive, a configuration associated with a measurement gap. For example, the RRC layer of the UE 120 may receive the configuration from the eNB 305 as described above in connection with reference number 510 of Fig. 5. As further shown in Fig. 6A, the RRC layer may pass the configuration to the MAC layer of the UE 120.

As shown in connection with reference number 615, the UE 120 may determine a conflict between the configurations. For example, the MAC layer of the UE 120 may determine the conflict similarly as described above with respect to the RRC layer in connection with reference number 515 of Fig. 5. In some aspects, the MAC layer may receive the configurations from the RRC layer and/or a PHY layer of the UE 120 in order to determine the conflict. For example, the RRC layer may maintain the configuration from the eNB 305, and/or the PHY layer may maintain the configuration from the gNB 310. In some aspects, the MAC layer may determine the conflict when initiating an SR procedure or initiating another transmission to the gNB 310. As an alternative, the MAC layer may determine the conflict when preparing to receive from the gNB 310.

Accordingly, in some aspects, the UE 120 may refrain from instructing a PHY layer of the UE 120 to use one or more symbols, scheduled for transmission or reception according to the configuration from the gNB 310, based at least in part on the conflict. For example, the MAC layer may determine that an SR or other transmission to the gNB 310 will not be transmitted by the PHY layer (e.g., due to the conflict) and may therefore refrain from instructing the PHY layer to attempt the transmission based at least in part on the determination. As an alternative, the MAC layer may determine that a transmission from the gNB 310 will not be received at the PHY layer (e.g., due to the conflict) and may therefore refrain from instructing the PHY layer to attempt to demodulate (and optionally perform at least some decoding of) the transmission based at least in part on the determination. As a result, the UE 120 may further conserve processing resources and power by refraining from instructing the PHY layer to use the one or more symbols.

In some aspects, and as shown in connection with reference number 620a, the UE 120 may switch logical channels. For example, the UE 120 may determine that one or more additional symbols, associated with a different logical channel than a logical channel associated with the one or more symbols, do not conflict with the measurement gap. As used herein, “logical channel” may refer to a channel, between a radio link control (RLC) layer and the MAC layer, that facilitates downlink communications from the gNB 310 (or the eNB 305) to the UE 120 and uplink communications from the UE 120 to the gNB 310 (or the eNB 305) . A logical channel may reside in the control plane and carry control information, or may reside in the user plane and carry data.

Accordingly, the UE 120 may instruct the PHY layer of the UE 120 to use the one or more additional symbols for transmission or reception, based at least in part on determining that the one or more additional symbols do not conflict with the measurement gap. As a result, the transmission to the gNB 310 or the reception from the gNB 310 may proceed, and the UE 120 reduces latency that would otherwise occur, and conserves processing resources, network overhead, and power that would otherwise be consumed, due to the conflict between the configurations.

Additionally, or alternatively, and as shown in connection with reference number 620b, the UE 120 may transmit, and the gNB 310 may receive, a random access preamble based at least in part on the conflict. For example, the UE 120 may initiate a RACH procedure in order to obtain a new configuration for transmitting to the gNB 310 or receiving from the gNB 310 (e.g., similar to how the UE 120 receives a new configuration as described above in connection with reference number 525b of Fig. 5) . The UE 120 may thus use the new configuration for the transmission to the gNB 310 or the reception from the gNB 310. As a result, the UE 120 pre-emptively avoids suffering latency and wasting processing resources, network overhead, and power due to the conflict between the configurations by obtaining the new configuration from the gNB 310.

By using techniques as described in connection with Fig. 6A, the MAC layer of the UE 120 may switch logical channels when transmitting to or receiving from the gNB 310 in order to avoid the conflict between the configurations. Thus, the UE 120 reduces latency that would otherwise occur, and conserves processing resources, network overhead, and power that would otherwise be consumed, due to the conflict between the configurations. Additionally, or alternatively, the MAC layer of the UE 120 may initiate a RACH procedure with the gNB 310 (e.g., by transmitting a random access preamble to the gNB 310) based at least in part on the conflict. Accordingly, the UE 120 may receive a new configuration associated with scheduling for transmitting or receiving (e.g., with the gNB 310) . As a result, the UE 120 reduces latency that would otherwise occur, and conserves processing resources, network overhead, and power that would otherwise be consumed, due to the conflict between the first configuration and the second configuration.

As indicated above, Fig. 6A is provided as an example. Other examples may differ from what is described with respect to Fig. 6A.

Fig. 6B is a diagram illustrating an example 650 associated with avoiding collisions with measurement gaps at a MAC layer, in accordance with the present disclosure. As shown in Fig. 6B, a UE 120 may be dual connected (e.g., as described above in connection with Fig. 3) with at least two base stations. In example 650, the UE 120 is dual connected with a gNB 310 associated with a 5G network and an eNB 305 associated with a legacy network (e.g., an LTE network or a 3G network) . Although described below using the gNB and the eNB, the description similarly applies to other dual connectivity configurations. For example, the UE 120 may be dual connected with two different 5G networks. Additionally, or alternatively, although described below as terrestrial, the description similarly applies to the gNB, the eNB, and/or another base station connected to the UE 120 being non-terrestrial (e.g., satellite-based) .

As shown in connection with reference number 655, the gNB 310 may transmit, and the UE 120 may receive, a configuration associated with scheduling for transmitting to the gNB 310 or receiving from the gNB 310. For example, an RRC layer of the UE 120 may receive the configuration from the gNB 310 as described above in connection with reference number 505 of Fig. 5. As further shown in Fig. 6B, the RRC layer may pass the configuration to the MAC layer of the UE 120.

As shown in connection with reference number 660, the eNB 305 may transmit, and the UE 120 may receive, a configuration associated with a measurement gap. For example, the RRC layer of the UE 120 may receive the configuration from the eNB 305 as described above in connection with reference number 510 of Fig. 5. As further shown in Fig. 6B, the RRC layer may pass the configuration to the MAC layer of the UE 120.

As shown in connection with reference number 665, the UE 120 may initiate a transmission to the gNB 310 or a reception from the gNB 310. For example, the MAC layer of the UE 120 may instruct a PHY layer of the UE 120 to use one or more symbols, scheduled for transmission according to the configuration from the gNB 310, to attempt to transmit an SR or another transmission to the gNB 310. As an alternative, the MAC layer of the UE 120 may instruct the PHY layer to attempt to demodulate (and optionally perform at least some decoding of) a transmission from the gNB 310, within one or more symbols that are scheduled for reception according to the configuration from the gNB 310.

As shown in connection with reference number 670, the PHY layer of the UE 120 may transmit, and the MAC layer of the UE 120 may receive, an indication that the one or more symbols were not used for transmission or reception. For example, the PHY layer may report an SR failure, another transmission failure, a measurement failure, and/or another reception failure. In some aspects, and as shown in connection with reference number 675, the transmission or the reception may fail because the PHY layer of the UE 120 is performing measurements within the measurement gap configured by the eNB 305 and/or transmitting a report based at least in part on those measurements to the eNB 305.

In some aspects, the MAC layer of the UE 120 may determine that the indication from the PHY layer is caused by a conflict between the configurations rather than radio channel conditions with the gNB 310 and/or another failure. For example, based at least in part on the indication from the PHY layer, the MAC layer may determine the conflict as described above in connection with reference number 615 of Fig. 6A.

In some aspects, and as shown in connection with reference number 680a, the UE 120 may switch logical channels. For example, the UE 120 may determine that one or more additional symbols, associated with a different logical channel than a logical channel associated with the one or more symbols, do not conflict with the measurement gap. Accordingly, the UE 120 may instruct the PHY layer of the UE 120 to use the one or more additional symbols for transmission or reception, based at least in part on determining that the one or more additional symbols do not conflict with the measurement gap. As a result, the transmission to the gNB 310 or the reception from the gNB 310 may proceed, and the UE 120 reduces latency that would otherwise occur, and conserves processing resources, network overhead, and power that would otherwise be consumed, due to the conflict between the configurations.

Additionally, or alternatively, and as shown in connection with reference number 680b, the UE 120 may transmit, and the gNB 310 may receive, a random access preamble based at least in part on the conflict. For example, the UE 120 may initiate a RACH procedure in order to obtain a new configuration for transmitting to the gNB 310 or receiving from the gNB 310 (e.g., similar to how the UE 120 receives a new configuration as described above in connection with reference number 525b of Fig. 5) . The UE 120 may thus use the new configuration for the transmission to the gNB 310 or the reception from the gNB 310. As a result, the UE 120 pre-emptively avoids suffering latency and wasting processing resources, network overhead, and power due to the conflict between the configurations by obtaining the new configuration from the gNB 310.

By using techniques as described in connection with Fig. 6B, the MAC layer of the UE 120 may switch logical channels when transmitting to or receiving from the gNB 310 in order to avoid the conflict between the configurations. Thus, the UE 120 reduces latency that would otherwise occur, and conserves processing resources, network overhead, and power that would otherwise be consumed, due to the conflict between the configurations. Additionally, or alternatively, the MAC layer of the UE 120 may initiate a RACH procedure with the gNB 310 (e.g., by transmitting a random access preamble to the gNB 310) based at least in part on the conflict. Accordingly, the UE 120 may receive a new configuration associated with scheduling for transmitting or receiving (e.g., with the gNB 310) . As a result, the UE 120 reduces latency that would otherwise occur, and conserves processing resources, network overhead, and power that would otherwise be consumed, due to the conflict between the first configuration and the second configuration.

As indicated above, Fig. 6B is provided as an example. Other examples may differ from what is described with respect to Fig. 6B.

Fig. 7 is a diagram illustrating an example 700 associated with avoiding collisions with measurement gaps at a PHY layer, in accordance with the present disclosure. As shown in Fig. 7, a UE 120 may be dual connected (e.g., as described above in connection with Fig. 3) with at least two base stations. In example 700, the UE 120 is dual connected with a gNB 310 associated with a 5G network and an eNB 305 associated with a legacy network (e.g., an LTE network or a 3G network) . Although described below using the gNB and the eNB, the description similarly applies to other dual connectivity configurations. For example, the UE 120 may be dual connected with two different 5G networks. Additionally, or alternatively, although described below as terrestrial, the description similarly applies to the gNB, the eNB, and/or another base station connected to the UE 120 being non-terrestrial (e.g., satellite-based) .

As shown in connection with reference number 705, the gNB 310 may transmit, and the UE 120 may receive, a configuration associated with scheduling for transmitting to the gNB 310 or receiving from the gNB 310. For example, an RRC layer of the UE 120 may receive the configuration from the gNB 310 as described above in connection with reference number 505 of Fig. 5. As further shown in Fig. 7, the RRC layer may pass the configuration to a MAC layer of the UE 120.

As shown in connection with reference number 710, the eNB 305 may transmit, and the UE 120 may receive, a configuration associated with a measurement gap. For example, the RRC layer of the UE 120 may receive the configuration from the eNB 305 as described above in connection with reference number 510 of Fig. 5. As further shown in Fig. 7, the RRC layer may pass the configuration to the MAC layer of the UE 120.

As shown in connection with reference number 715, the UE 120 may initiate a transmission to the gNB 310 or a reception from the gNB 310. For example, the MAC layer of the UE 120 may instruct the PHY layer of the UE 120 to use one or more symbols, scheduled for transmission according to the configuration from the gNB 310, to attempt to transmit an SR or another transmission to the gNB 310. As an alternative, the MAC layer of the UE 120 may instruct the PHY layer to attempt to demodulate (and optionally perform at least some decoding of) a transmission from the gNB 310, within one or more symbols that are scheduled for reception according to the configuration from the gNB 310.

In some aspects, and as shown in connection with reference number 720a, the PHY layer of the UE 120 may refrain from measuring during (and thus skip) a current measurement gap. Accordingly, as shown in connection with reference number 730, the UE 120 may transmit to the gNB 310 or receive from the gNB 310. Thus, the UE 120 may determine the conflict before the current measurement gap, and the UE 120 may transmit to or receive from the gNB 310 by skipping the current measurement gap. The PHY layer may resume measurements at a next measurement gap.

As an alternative, and as shown in connection with reference number 720b, the UE 120 may determine the conflict during the current measurement gap. For example, the PHY layer may be performing measurements within the current measurement gap configured by the eNB 305 and/or transmitting a report based at least in part on those measurements to the eNB 305. Accordingly, in some aspects, and as shown in connection with reference number 725a, the PHY layer of the UE 120 may exit the current measurement gap and, as shown in connection with reference number 730, may transmit to the gNB 310 or receive from the gNB 310. Thus, the UE 120 may determine the conflict during the current measurement gap, and the UE 120 may transmit to or receive from the gNB 310 by skipping the current measurement gap. The PHY layer may resume measurements at a next measurement gap.

As an alternative, and as shown in connection with reference number 725b, the PHY layer of the UE 120 may refrain from measuring during (and thus skip) a next measurement gap. For example, the PHY layer may configure instructions to skip the next measurement gap based at least in part on the instruction, from the MAC layer, to transmit or receive. Accordingly, as shown in connection with reference number 730, the UE 120 may transmit to the gNB 310 or receive from the gNB 310. Thus, the UE 120 may determine the conflict during the current measurement gap, and the UE 120 may transmit to or receive from the gNB 310 by skipping the next measurement gap. The PHY layer may resume measurements at a measurement gap that follows the next measurement gap.

In any of the aspects described above, the UE 120 may determine that an indicator of a radio condition associated with the UE 120 satisfies a threshold. For example, the PHY layer of the UE 120 may determine that an RSRP, an RSSI, another L1 measurement, and/or another indicator of channel quality between the UE 120 and the eNB 305 satisfies the threshold. The threshold may be indicated by the eNB 305, indicated by the gNB 310, and/or programmed (or otherwise preconfigured) into the UE 120 (e.g., according to 3GPP specifications and/or another standard) . Accordingly, the PHY layer may skip the current measurement gap or the next measurement gap based at least in part on the indicator of the radio condition satisfying the threshold.

By using techniques as described in connection with Fig. 7, the PHY layer of the UE 120 may skip or exit a current measurement gap in order to perform a transmission or reception (e.g., with the gNB 310) . As an alternative, the PHY layer of the UE 120 may skip a next measurement gap in order to perform the transmission or reception. As a result, the UE 120 reduces latency that would otherwise occur, and conserves processing resources, network overhead, and power that would otherwise be consumed, due to the conflict between the first configuration and the second configuration.

As indicated above, Fig. 7 is provided as an example. Other examples may differ from what is described with respect to Fig. 7.

Fig. 8 is a diagram illustrating an example process 800 performed, for example, by a UE, in accordance with the present disclosure. Example process 800 is an example where the UE (e.g., UE 120 and/or apparatus 1100 of Fig. 11) performs operations associated with avoiding collisions with measurement gaps.

As shown in Fig. 8, in some aspects, process 800 may include determining that one or more symbols, scheduled for transmitting to a base station (e.g., base station 110, gNB 310, and/or apparatus 1200 of Fig. 12) or receiving from the base station, conflict with a measurement gap (block 810) . For example, the UE (e.g., using determination component 1108, depicted in Fig. 11) may determine that one or more symbols, scheduled for transmitting to a base station or receiving from the base station, conflict with a measurement gap, as described above.

As further shown in Fig. 8, in some aspects, process 800 may include transmitting a random access preamble based at least in part on determining the conflict (block 820) . For example, the UE (e.g., using transmission component 1104, depicted in Fig. 11) may transmit a random access preamble based at least in part on determining the conflict, as described above.

In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, process 800 further includes receiving (e.g., using determination component 1108) , from a physical layer of the UE, an indication that the one or more symbols were not used for transmission or reception, such that the conflict is determined based at least in part on the indication.

In an eighth aspect, alone or in combination with one or more of the first through seventh aspects, process 800 further includes refraining (e.g., using determination component 1108) from instructing a physical layer of the UE to use the one or more symbols for transmission or reception, based at least in part on determining the conflict.

In a ninth aspect, alone or in combination with one or more of the first through eighth aspects, process 800 further includes determining (e.g., using determination component 1108) that one or more additional symbols, associated with a different logical channel than a logical channel associated with the one or more symbols, do not conflict with the measurement gap, and instructing (e.g., using determination component 1108) a physical layer of the UE to use the one or more additional symbols for transmission or reception, based at least in part on determining that the one or more additional symbols do not conflict with the measurement gap.

Although Fig. 8 shows example blocks of process 800, in some aspects, process 800 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in Fig. 8. Additionally, or alternatively, two or more of the blocks of process 800 may be performed in parallel.

Fig. 9 is a diagram illustrating an example process 900 performed, for example, by a UE, in accordance with the present disclosure. Example process 900 is an example where the UE (e.g., UE 120 and/or apparatus 1100 of Fig. 11) performs operations associated with avoiding collisions with measurement gaps.

As shown in Fig. 9, in some aspects, process 900 may include determining that one or more symbols, scheduled for transmitting to a base station (e.g., base station 110, gNB 310, and/or apparatus 1200 of Fig. 12) or receiving from the base station, conflict with a measurement gap (block 910) . For example, the UE (e.g., using determination component 1108, depicted in Fig. 11) may determine that one or more symbols, scheduled for transmitting to a base station or receiving from the base station, conflict with a measurement gap, as described above.

As further shown in Fig. 9, in some aspects, process 900 may include transmitting to the base station, or receiving from the base station, by refraining from measuring during a current measurement gap or a next measurement gap, based at least in part on determining the conflict (block 920) . For example, the UE (e.g., using transmission component 1104, depicted in Fig. 11) may transmit to the base station, or receiving from the base station, by refraining from measuring during a current measurement gap or a next measurement gap, based at least in part on determining the conflict, as described above.

In a first aspect, the measurement gap is periodic.

In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, process 900 further includes determining (e.g., using determination component 1108) that an indicator of a radio condition associated with the UE satisfies a threshold, and refraining from measuring during the current measurement gap or the next measurement gap is based at least in part on the indicator satisfying the threshold.

In an eighth aspect, alone or in combination with one or more of the first through seventh aspects, the conflict is determined before the current measurement gap, and the base station is transmitted to or received from by skipping the current measurement gap.

In a ninth aspect, alone or in combination with one or more of the first through eighth aspects, the conflict is determined during the current measurement gap, and the base station is transmitted to or received from by exiting the current measurement gap.

In a tenth aspect, alone or in combination with one or more of the first through ninth aspects, the conflict is determined during the current measurement gap, and the base station is transmitted to or received from by skipping the next measurement gap.

Although Fig. 9 shows example blocks of process 900, in some aspects, process 900 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in Fig. 9. Additionally, or alternatively, two or more of the blocks of process 900 may be performed in parallel.

Fig. 10 is a diagram illustrating an example process 1000 performed, for example, by a UE, in accordance with the present disclosure. Example process 1000 is an example where the UE (e.g., UE 120 and/or apparatus 1100 of Fig. 11) performs operations associated with avoiding collisions with measurement gaps.

As shown in Fig. 10, in some aspects, process 1000 may include receiving a first configuration associated with a measurement gap and a second configuration associated with scheduling for transmitting to a base station (e.g., base station 110, gNB 310, and/or apparatus 1200 of Fig. 12) or receiving from the base station (block 1010) . For example, the UE (e.g., using reception component 1102, depicted in Fig. 11) may receive a first configuration associated with a measurement gap and a second configuration associated with scheduling for transmitting to a base station or receiving from the base station, as described above.

As further shown in Fig. 10, in some aspects, process 1000 may include transmitting a rejection of the first configuration or a rejection of the second configuration based at least in part on determining a conflict between the first configuration and the second configuration (block 1020) . For example, the UE (e.g., using transmission component 1104, depicted in Fig. 11) may transmit a rejection of the first configuration or a rejection of the second configuration based at least in part on determining a conflict between the first configuration and the second configuration, as described above.

Process 1000 may include additional aspects, such as any single aspect or any combination of aspects described below and/or in connection with one or more other processes described elsewhere herein.

In a first aspect, the measurement gap is periodic.

In a fifth aspect, alone or in combination with one or more of the first through fourth aspects, the second configuration is associated with an SR, a PUSCH, or another transmission from the UE to the base station.

In a sixth aspect, alone or in combination with one or more of the first through fifth aspects, the second configuration is associated with an SSB, a CSI-RS, a PDSCH, or another transmission to the UE from the base station.

In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, the conflict is determined based at least in part on one or more symbols associated with the second configuration overlapping with the measurement gap.

Although Fig. 10 shows example blocks of process 1000, in some aspects, process 1000 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in Fig. 10. Additionally, or alternatively, two or more of the blocks of process 1000 may be performed in parallel.

Fig. 11 is a block diagram of an example apparatus 1100 for wireless communication. The apparatus 1100 may be a UE, or a UE may include the apparatus 1100. In some aspects, the apparatus 1100 includes a reception component 1102 and a transmission component 1104, which may be in communication with one another (for example, via one or more buses and/or one or more other components) . As shown, the apparatus 1100 may communicate with another apparatus 1106 (such as a UE, a base station, or another wireless communication device) using the reception component 1102 and the transmission component 1104. As further shown, the apparatus 1100 may include a determination component 1108, among other examples.

In some aspects, the apparatus 1100 may be configured to perform one or more operations described herein in connection with Figs. 5-7. Additionally, or alternatively, the apparatus 1100 may be configured to perform one or more processes described herein, such as process 800 of Fig. 8, process 900 of Fig. 9, process 1000 of Fig. 10, or a combination thereof. In some aspects, the apparatus 1100 and/or one or more components shown in Fig. 11 may include one or more components of the UE described above in connection with Fig. 2. Additionally, or alternatively, one or more components shown in Fig. 11 may be implemented within one or more components described above in connection with Fig. 2. Additionally, or alternatively, one or more components of the set of components may be implemented at least in part as software stored in a memory. For example, a component (or a portion of a component) may be implemented as instructions or code stored in a non-transitory computer-readable medium and executable by a controller or a processor to perform the functions or operations of the component.

The reception component 1102 may receive communications, such as reference signals, control information, data communications, or a combination thereof, from the apparatus 1106. The reception component 1102 may provide received communications to one or more other components of the apparatus 1100. In some aspects, the reception component 1102 may perform signal processing on the received communications (such as filtering, amplification, demodulation, analog-to-digital conversion, demultiplexing, deinterleaving, de-mapping, equalization, interference cancellation, or decoding, among other examples) , and may provide the processed signals to the one or more other components of the apparatus 1106. In some aspects, the reception component 1102 may include one or more antennas, a demodulator, a MIMO detector, a receive processor, a controller/processor, a memory, or a combination thereof, of the UE described above in connection with Fig. 2.

The transmission component 1104 may transmit communications, such as reference signals, control information, data communications, or a combination thereof, to the apparatus 1106. In some aspects, one or more other components of the apparatus 1106 may generate communications and may provide the generated communications to the transmission component 1104 for transmission to the apparatus 1106. In some aspects, the transmission component 1104 may perform signal processing on the generated communications (such as filtering, amplification, modulation, digital-to-analog conversion, multiplexing, interleaving, mapping, or encoding, among other examples) , and may transmit the processed signals to the apparatus 1106. In some aspects, the transmission component 1104 may include one or more antennas, a modulator, a transmit MIMO processor, a transmit processor, a controller/processor, a memory, or a combination thereof, of the UE described above in connection with Fig. 2. In some aspects, the transmission component 1104 may be co-located with the reception component 1102 in a transceiver.

In some aspects, the determination component 1108 may determine that one or more symbols, scheduled for transmitting to the apparatus 1106 or receiving from the apparatus 1106, conflict with a measurement gap. The determination component 1108 may include a MIMO detector, a receive processor, a transmit MIMO processor, a transmit processor, a controller/processor, a memory, or a combination thereof, of the UE described above in connection with Fig. 2. Accordingly, the transmission component 1104 may transmit (e.g., to the apparatus 1106) a random access preamble based at least in part on the determination component 1108 determining the conflict. In some aspects, the determination component 1108 (e.g., at least partially included in a MAC layer of the apparatus 1100) may receive, from the reception component 1102 and/or the transmission component 1104 (e.g., at least partially included in a PHY layer of the apparatus 1100) , an indication that the one or more symbols were not used for transmission or reception. Accordingly, the determination component 1108 may determine the conflict based at least in part on the indication. Additionally, or alternatively, the determination component 1108 (e.g., at least partially included in a MAC layer of the apparatus 1100) may refrain from instructing the reception component 1102 and/or the transmission component 1104 (e.g., at least partially included in a PHY layer of the apparatus 1100) to use the one or more symbols for reception or transmission, respectively, based at least in part on the determination component 1108 determining the conflict.

In some aspects, the determination component 1108 may further determine that one or more additional symbols, associated with a different logical channel than a logical channel associated with the one or more symbols, do not conflict with the measurement gap.
