[0002] This patent application claims priority to Patent Cooperation Treaty (PCT) patent application number PCT / CN2020 / 089929, entitled “COLLISION HANDLING FORSOUNDING REFERENCE SIGNAL GUARD PERIOD AND PUSCH TRANSMISSION”, filed on May 13, 2020, and the assignee assigned to the present application. The disclosure of the prior application is considered a part of and incorporated by reference into the present patent application. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and techniques and apparatus for collision handling for collisions between sounding reference signal (SRS) guard periods and physical uplink shared channel (PUSCH) transmissions. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE) systems. 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).

[0005] A wireless network may include multiple base stations (BSs) that may support communications for multiple user equipment (UEs). A UE may communicate with a BS via a downlink and an uplink. A "downlink" (or "forward link") refers to a communication link from a BS to a UE, and an "uplink" (or "reverse link") refers to a communication link from a UE to a BS. As described in more detail herein, a BS may refer to 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, and the like.

[0006] 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 a city, country, regional, and even global level. NR, which can also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR aims to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, using orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) (CP-OFDM) on the downlink (DL) and 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. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] 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 construed as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and to 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 the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or implement a method. In addition, the scope of the present disclosure is intended to cover such a device or method, which is practiced using other structures, functions, or structures and functions other than or in addition to the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein can be embodied by one or more elements of the claims.

[0027] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using 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.

[0028] It should be noted that although various aspects may be described herein using terminology generally associated with 5G or NR radio access technologies (RATs), various aspects of the present disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and / or RATs beyond 5G (e.g., 6G).

[0029] Figure 1 is a diagram showing an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and / or an LTE network, among others. The wireless network 100 may include a plurality of base stations 110 (shown as BS110a, BS 110b, BS110c, and BS110d) 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), and the like. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0030] 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., a radius of several kilometers) and may allow unrestricted access to UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access to UEs with service subscriptions. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access to UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In Figure 1 In the example shown, BS 110a may be a macro BS of macro cell 102a, BS 110b may be a pico BS of pico cell 102b, and BS 110c may be a femto BS 102c of a femto cell. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "Node B", "5G NB", and "cell" may be used interchangeably herein.

[0031] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other 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 direct physical connections or virtual networks using any suitable transport network.

[0032] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions 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. Figure 1 In the example shown, a relay BS 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, or the like.

[0033] The wireless network 100 may be a heterogeneous network including different types of BSs, such as macro BSs, pico BSs, femto BSs, relay BSs, etc. These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0034] The network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0035] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be fixed or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0036] Some UEs may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors and / or location tags, which can communicate with a base station, another device (e.g., a remote device), or some other entity. For example, a wireless node may provide connectivity to a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included in a housing that houses components (e.g., processor components and / or memory components) of UE 120. In some aspects, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electrically coupled, and / or electrically coupled.

[0037] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0038] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UE 120 can communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol or vehicle-to-infrastructure (V2I) protocol), and / or mesh network. In this case, UE 120 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0039] The 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, the devices of the wireless network 100 can communicate using an operating frequency band having a first frequency range (FR1), which can range from 410 MHz to 7.125 GHz, and / or can communicate using an operating frequency band having a second frequency range (FR2), which can range from 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" frequency band. Similarly, FR2 is often referred to as a "millimeter wave" frequency band, although it is different from the extremely high frequency (EHF) frequency band (30 GHz–300 GHz) identified as "millimeter wave" by the International Telecommunication Union (ITU). Therefore, unless otherwise expressly stated, it should be understood that the term "sub-6 GHz", etc., if used herein, can broadly represent frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise expressly stated, it should be understood that the term "millimeter wave" and the like, if used herein, can broadly refer to frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than or equal to 24.25 GHz). It is contemplated that frequencies within FR1 and FR2 may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0040] As mentioned above, providing Figure 1As an example. Other examples may be related to Figure 1 Different than described.

[0041] Figure 2 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. 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.

[0042] At the base station 110, the transmit processor 220 may receive data from the 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 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) or secondary synchronization signals (SSS)). If applicable, 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, and may provide T output symbol streams to T modulators (MOD) 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 (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0043] At the UE 120, antennas 252a to 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM) to obtain received symbols. The MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to the data sink 260, and provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or 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, etc. In some aspects, one or more components of the UE 120 may be included in the housing 284.

[0044] 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.

[0045] 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, antenna element groups, and / or antenna arrays, among others. Antenna panels, antenna groups, antenna element groups, and / or antenna arrays may include one or more antenna elements. Antenna panels, antenna groups, antenna element groups, and / or antenna arrays may include a group of coplanar antenna elements and / or a group of non-coplanar antenna elements. Antenna panels, antenna groups, antenna element groups, and / or antenna arrays may include antenna elements within a single housing and / or antenna elements within multiple housings. Antenna panels, antenna groups, antenna element groups, and / or antenna arrays may include antennas coupled to one or more transmit and / or receive components (e.g., antennas ... Figure 2 One or more antenna elements of one or more components in.

[0046] 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 a controller / processor 280. The transmit processor 264 may also generate reference symbols for one or more reference signals. If applicable, the symbols from the transmit processor 264 may be precoded by a TX MIMO processor 266, further processed by 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 antennas 252, modulators and / or demodulators 254, MIMO detectors 256, receive processors 258, transmit processors 264, and / or TX MIMO processors 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., as described in reference to Figures 5 to 8 described above).

[0047] At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 to schedule the UE 120 for downlink and / or uplink communications. In some aspects, the modulator and 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 antennas 234, modulators and / or demodulators 232, MIMO detectors 236, receive processors 238, transmit processors 220, and / or TX MIMO processors 230. A processor (e.g., controller / processor 240) and memory 242 may use the transceiver to perform aspects of any of the methods described herein (e.g., as described in reference to Figures 5 to 8 described above).

[0048] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component of the base station 110 may perform one or more techniques associated with conflict handling for conflicts between sounding reference signal (SRS) protection periods and physical uplink shared channel (PUSCH) transmissions, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the can perform or direct e.g. Figure 7 The process 700 Figure 8 800, and / or operations of other processes 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, 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 one or more processors, UE 120, and / or base station 110 to perform or direct, for example, Figure 7 The process 700 Figure 8 The operations of process 800 and / or other processes described herein. In some aspects, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among others.

[0049] In some aspects, UE 120 may include means for identifying a conflict between a PUSCH transmission and a guard period of an SRS transmission, wherein the SRS transmission includes a first SRS transmission and a second SRS transmission, the second SRS transmission using a first set of one or more antenna ports of the UE, and the PUSCH transmission using a second set of one or more antenna ports of the UE; means for performing an action to mitigate the conflict based at least in part on identifying the conflict, and the like. In some aspects, such means may include combining Figure 2 One or more components of the UE 120, such as the controller / processor 280, the transmit processor 264, the TX MIMO processor 266, the MOD 254, the antenna 252, the DEMOD 254, the MIMO detector 256, the receive processor 258, etc.

[0050] In some aspects, the base station 110 may include a unit for identifying a conflict between a protection period of a PUSCH transmission and an SRS transmission, wherein the SRS transmission includes a first SRS transmission and a second SRS transmission, the second SRS transmission uses a first set of one or more antenna ports of the UE, and the PUSCH transmission uses a second set of one or more antenna ports of the UE; a unit for determining an action to be performed by the UE to mitigate the conflict based at least in part on identifying the conflict; a unit for selectively receiving the PUSCH transmission or the SRS transmission based at least in part on determining the action, etc. In some aspects, such a unit may include a combination of Figure 2 One or more components of the base station 110 are described, for example, antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and the like.

[0051] Although Figure 2 The blocks in the 2000 and 2000 are illustrated as different components, but the functions described above with respect to these blocks may be implemented in a single hardware, software, or combined 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 the controller / processor 280.

[0052] As mentioned above, providing Figure 2 As an example. Other examples may be related to Figure 2 Different than described.

[0053] Figure 3 is a diagram illustrating an example 300 of a frame structure in a wireless communication network according to the present disclosure. Figure 3 The frame structure shown in is used for frequency division duplex (FDD) in telecommunication systems such as LTE and / or NR, etc. The transmission timeline of each of the downlink and uplink may be divided into radio frame units (sometimes referred to as frames). Each radio frame may have a predetermined duration (e.g., 10 milliseconds (ms)) and may be divided into a set of Z (Z ≥ 1) subframes (e.g., with indices from 0 to Z-1). Each subframe may have a predetermined duration (e.g., 1 ms) and may include a set of time slots (e.g., Figure 3 2m time slots per subframe are shown in FIG, where m is the index of the parameter set used for transmission, e.g., 0, 1, 2, 3, and / or 4, etc.). Each time slot may include a set of L symbol periods. For example, each time slot may include fourteen symbol periods (e.g., Figure 3In some aspects, the scheduling unit for FDD can be frame-based, subframe-based, slot-based, mini-slot-based, and / or symbol-based, etc.

[0054] In some aspects, a wireless frame may include one or more downlink time slots (e.g., time slots in which downlink communications may be scheduled), one or more uplink time slots (e.g., time slots in which uplink communications may be scheduled), and / or one or more special time slots (e.g., time slots in which downlink communications or uplink communications may be scheduled).

[0055] As mentioned above, providing Figure 3 As an example. Other examples may be related to Figure 3 Different than described.

[0056] Figure 4 An example 400 of an antenna port in accordance with the present disclosure is shown.

[0057] like Figure 4 As shown, the first physical antenna 405-1 can send information via the first channel h1, the second physical antenna 405-2 can send information via the second channel h2, the third physical antenna 405-3 can send information via the third channel h3, and the fourth physical antenna 405-4 can send information via the fourth channel h4. Such information can be transmitted via a logical antenna port, which can represent some combination of physical antennas and / or channels. In some cases, UE 120 may have knowledge of the channels associated with the physical antennas and can operate based solely on the knowledge of the channels associated with the antenna ports, as defined below.

[0058] An antenna port may be defined such that the channel on which a symbol on the antenna port is transmitted may be inferred from the channel on which another symbol on the same antenna port is transmitted. In example 400, the channels associated with antenna port 1 (AP1) are represented as h1-h2+h3+j*h4, where the channel coefficients (e.g., 1, -1, 1, and j in this case) represent weighting factors (e.g., indicating phase and / or gain) applied to each channel. Such weighting factors may be applied to channels to improve signal power and / or signal quality at one or more receivers. Applying such weighting factors to channel transmissions may be referred to as precoding, and "precoder" may refer to a particular set of weighting factors applied to a set of channels.

[0059] Similarly, the channel associated with antenna port 2 (AP2) is represented as h1+j*h3, and the channel associated with antenna port 3 (AP3) is represented as 2*h1-h2+(1+j)*h3+j*h4. In this case, antenna port 3 can be represented as the sum of antenna port 1 and antenna port 2 (e.g., AP3=AP1+AP2) because the sum of the expression (h1-h2+h3+j*h4) representing antenna port 1 and the expression (h1+j*h3) representing antenna port 2 is equal to the expression (2*h1-h2+(1+j)*h3+j*h4) representing antenna port 3. It can also be said that antenna port 3 is related to antenna port 1 and antenna port 2 [AP1,AP2] via precoder [1,1] because 1 times the expression representing antenna port 1 plus 1 times the expression representing antenna port 2 is equal to the expression representing antenna port 3.

[0060] As mentioned above, only Figure 4 As an example. Other examples may be related to Figure 4 Different than described.

[0061] In a wireless network, a UE may be configured to perform antenna switching when performing one or more uplink transmissions. For example, in a sounding reference signal (SRS) configuration, the UE may be configured to use one or more antenna ports of different groups to send one or more SRS transmissions. When performing antenna switching, the UE may perform one or more RF switches associated with connecting the antenna ports to the physical antenna modules. In some cases, the SRS transmission associated with the antenna switching may be associated with a protection period. The protection period may be the number of symbols associated with the amount of time required for the UE to perform one or more RF switches. The UE may be configured not to send any signal during the protection period to allow the UE to perform one or more RF switches.

[0062] In some cases, the base station may schedule or configure a physical uplink shared channel (PUSCH) transmission in an uplink time slot after the time slot in which the SRS transmission is configured. The SRS transmission may be configured in the last group of one or more symbols in the time slot. However, the SRS transmission and the PUSCH transmission may be one or more antenna ports of different groups for transmission (for example, the UE may need to perform antenna switching between transmitting the SRS transmission and transmitting the PUSCH transmission). Therefore, the SRS transmission may be associated with a protection period extending into the uplink time slot containing the PUSCH transmission. This may be referred to as a conflict between the SRS protection period and the PUSCH transmission. Because the UE may be configured not to send any signal during the protection period, one or more symbols associated with the PUSCH transmission may be discarded. This may cause the UE to consume network resources (e.g., time resources, frequency resources, space resources, resource elements, etc.) associated with increasing retransmissions for the UE, and / or may cause uplink transmission delays, and the like.

[0063] Some techniques and apparatus described herein enable a UE to perform conflict handling for conflicts between SRS protection periods and PUSCH transmissions. For example, the UE may be able to identify a conflict and perform an action (e.g., not sending an SRS transmission or a PUSCH transmission) based at least in part on identifying the conflict and applying one or more priority rules. Thus, the UE may ensure that uplink communications based at least in part on the conflict are not corrupted or discarded. This may save network resources that would otherwise be used to send retransmissions of lost uplink communications, may reduce delays in uplink transmissions, and the like.

[0064] Figure 5 5 is a diagram illustrating an example 500 of conflict handling for conflicts between SRS protection periods and PUSCH transmissions according to the present disclosure. Figure 5 As shown, base station 110 and UE 120 may communicate with each other in a wireless network (eg, network 100).

[0065] As indicated by reference numeral 505, the base station 110 may send an SRS resource configuration. For example, the base station 110 may configure the UE 120 with one or more SRS resource sets to allocate resources for SRS transmissions performed by the UE 120. The configuration for the SRS resource set may be indicated in an SRS resource configuration (sometimes referred to as an SRS configuration, an SRS resource set configuration, etc.). In some aspects, the SRS resource configuration may be indicated in a radio resource control (RRC) message (e.g., an RRC configuration message and / or an RRC reconfiguration message). The SRS resource configuration may indicate one or more resources included in the SRS resource set. Resources may include time resources, frequency resources, space resources, etc. (e.g., time slots, symbols, resource blocks, periodicity of time resources, beams, and / or spatial references).

[0066] The SRS resource configuration may indicate one or more antenna ports via which the SRS is to be sent in an SRS resource (e.g., in a time-frequency resource, a spatial resource, etc.). Thus, an SRS resource configuration for an SRS resource set may indicate one or more resources in which the SRS is to be sent, and may indicate one or more antenna ports on which the SRS is to be sent in those resources. In some aspects, an SRS configuration for an SRS resource set may indicate a purpose for the SRS resource set (e.g., an SRS purpose, sometimes referred to as a use case, may be indicated in an SRS-ResourceSet information element). For example, an SRS resource set may have purposes for antenna switching, codebook, non-codebook, beam management (sometimes referred to as uplink beam management), etc.

[0067] The antenna switching SRS resource set may be used to indicate downlink channel state information (CSI) when there is reciprocity between the uplink and downlink channels. For example, when there is reciprocity between the uplink channel and the downlink channel, the base station 110 may use the antenna switching SRS (e.g., an SRS sent using resources of the antenna switching SRS resource set) to acquire downlink CSI (e.g., to determine a downlink precoder for communicating with the UE 120 and / or to estimate a downlink channel). Therefore, in some cases, the antenna switching purpose may be referred to as a downlink acquisition purpose.

[0068] In some aspects, the SRS resource configuration may indicate a single antenna port for an SRS resource set. In some aspects, the SRS configuration may indicate multiple antenna ports (e.g., two antenna ports, three antenna ports, and / or other number of antenna ports) for an SRS resource set. In some aspects, the SRS resource configuration may indicate several SRS resource sets configured for UE 120. Additionally or alternatively, the SRS configuration may indicate the purpose for those SRS resource sets, thereby indicating several SRS resources configured for each specific purpose. Additionally or alternatively, the SRS configuration may indicate a time domain configuration for an SRS resource set, such as whether the SRS resource set is periodic, aperiodic, semi-persistent, and the like. Additionally or alternatively, the SRS configuration may indicate a periodicity for an SRS resource set (e.g., the frequency at which the SRS is sent in the time domain for an SRS resource set).

[0069] For example, the SRS resource configuration may indicate that the antenna switching SRS resource set includes a first SRS resource and a second SRS resource. In addition, the capability of UE 120 may indicate the number of SRS ports per SRS resource (e.g., the number of antenna ports), which is based at least in part on the number of antennas of UE 120 (e.g., supportedSRS-TxPortSwitch capability). For example, the capability of UE 120 may indicate that UE 120 has 4 antennas and each SRS resource will be associated with 2 SRS ports. In some aspects, the supportedSRS-TxPortSwitch capability may be 2T4R, indicating that up to 2 SRS resource sets may be supported and each SRS resource set may include 2 SRS resources. Each SRS resource may be sent on different symbols. Each SRS resource may be associated with 2 SRS ports. The first SRS resource may use the first 2 antenna ports and the second SRS resource may use the last 2 antenna ports. Thus, an antenna switching SRS may be sent in a first SRS transmission using first SRS resources (e.g., first time-frequency resources) using a first set of antenna ports of UE 120 (e.g., antenna ports 0 and 1), and an SRS may be sent in a second SRS transmission using second SRS resources (e.g., second time-frequency resources) using a second set of antenna ports of UE 120 (e.g., antenna ports 2 and 3).

[0070] In some aspects, the SRS resource configuration may indicate a priority associated with the SRS resource. For example, the SRS resource configuration may indicate that the SRS resource is associated with priority 1 or priority 2 (e.g., as defined by a wireless communication standard such as a 3GPP specification or otherwise defined). In some aspects, priority 1 may represent a higher priority (e.g., a higher importance) than priority 2. In some aspects, priority 1 may be associated with aperiodic SRS resources. In some aspects, priority 2 may be associated with semi-persistent SRS resources and periodic SRS resources.

[0071] The SRS resource configuration may indicate that the SRS resource set includes one or more guard periods (e.g., the number of symbols in which the UE 120 does not transmit any signal). For example, the SRS resource set may include a guard period between a first SRS transmission and a second SRS transmission (e.g., between a first SRS resource and a second SRS resource). Similarly, the SRS resource set may include a guard period after the second SRS transmission. For example, the second SRS transmission may be configured to use a second set of antenna ports (e.g., antenna ports 2 and 3) of the UE 120. The UE 120 may need to perform antenna switching to transmit a signal after the second SRS transmission (e.g., if the uplink transmission after the second SRS transmission uses the first set of antenna ports, such as antenna ports 0 and 1).

[0072] As shown by reference numeral 510, UE 120 may identify a conflict between the guard periods of the PUSCH transmission and the SRS transmission. For example, base station 110 may schedule the PUSCH transmission to occur in the next time slot after the time slot in which the SRS transmission is configured. The PUSCH transmission and the SRS transmission may be configured to be transmitted on the same component carrier (e.g., using the same frequency).

[0073] UE 120 may identify a conflict based at least in part on determining that the second SRS transmission is associated with a protection period (e.g., based at least in part on determining that UE 120 must perform antenna switching between the second SRS transmission and the PUSCH transmission). In some aspects, UE 120 may identify a conflict based at least in part on determining that the SRS resource set includes the first SRS resource and the second SRS resource and determining that the SRS usage includes antenna switching. In some aspects, UE 120 may identify a conflict based at least in part on determining that the SRS transmission is configured to be transmitted so that the last symbol of the SRS transmission (e.g., the last symbol of the second SRS transmission) is the last symbol of the first time slot, and determining that the PUSCH transmission is scheduled or configured to be transmitted in a next time slot after the first time slot (e.g., a time slot after the first time slot in the time domain). The first time slot may be an uplink time slot or a special time slot. The next time slot after the first time slot may be an uplink time slot.

[0074] As indicated by reference numeral 515, the base station 110 may identify a conflict in a similar manner as described above with respect to the UE 120. For example, the base station 110 may identify an SRS resource configuration and a PUSCH transmission that is scheduled or configured (e.g., by the base station 110) and may identify a conflict between a guard period of the SRS transmission and the PUSCH transmission.

[0075] As indicated by reference numeral 520, UE 120 may determine whether to send a PUSCH transmission or an SRS transmission. For example, UE 120 may determine an action to be performed (e.g., not sending an SRS transmission or not sending a PUSCH transmission) to mitigate the conflict based at least in part on identifying the conflict. UE 120 may determine whether to send a PUSCH transmission or an SRS transmission based at least in part on a priority rule associated with the conflict. The priority rule may be based at least in part on a time domain configuration for SRS transmission (e.g., aperiodic, periodic, or semi-persistent), content of the PUSCH transmission, and / or a priority of the SRS transmission (e.g., which may be indicated by the time domain configuration for the SRS transmission), and the like.

[0076] For example, the PUSCH transmission may be a time-division multiplexed PUSCH transmission. That is, the PUSCH transmission and the physical uplink control channel (PUCCH) transmission may be combined using time-division multiplexing. The PUCCH transmission may include a channel state information (CSI) report, a layer one (L1) reference signal received power (RSRP) report, an L1 signal to interference and noise ratio (SINR) report, a hybrid automatic repeat request (HARQ-ACK), a link recovery request, and / or a scheduling request, etc.

[0077] In some aspects, the priority rules may indicate that when the SRS transmission is a semi-persistent SRS transmission or a periodic SRS transmission (e.g., a priority 2 SRS transmission), and the PUSCH transmission is time-division multiplexed with a PUCCH transmission including a CSI report, an L1-RSRP report, or an L1-SINR report, the UE 120 will avoid sending an SRS transmission (e.g., not sending an SRS transmission but sending a PUSCH transmission).

[0078] In some aspects, the priority rules may indicate that UE 120 will avoid sending SRS transmissions (e.g., not sending SRS transmissions but sending PUSCH transmissions) when the SRS transmission is a semi-persistent SRS transmission, a periodic SRS transmission, or an aperiodic SRS transmission, and the PUSCH transmission is time division multiplexed with a PUCCH transmission including a HARQ-ACK, a link recovery request, or a scheduling request.

[0079] In some aspects, the priority rules may indicate that when the SRS transmission is an aperiodic SRS transmission (e.g., a priority 1 SRS transmission) and the PUSCH transmission is not time-division multiplexed with the PUCCH transmission, the UE 120 will avoid sending the PUSCH transmission (e.g., not sending the PUSCH transmission, but sending the SRS transmission). In some aspects, the priority rules may indicate that when the SRS transmission is an aperiodic SRS transmission and the PUSCH transmission is time-division multiplexed with a PUCCH transmission including a CSI report, an L1-RSRP report, or an L1-SINR report, the UE 120 will avoid sending the PUSCH transmission.

[0080] In some aspects, the priority rule may be based at least in part on the priority of the SRS transmission. For example, as described above, the SRS transmission may be priority 1 or priority 2, etc. (e.g., in some cases, the priority may be defined by a 3GPP specification or otherwise defined). The UE 120 may identify the priority of the SRS transmission based at least in part on an indication from the base station 110 (e.g., in an SRS resource configuration) and / or based at least in part on a priority indicator field associated with the SRS transmission, etc. For example, the SRS transmission may be prioritized by traffic type (e.g., an enhanced mobile broadband (eMBB) SRS transmission may have a different priority than an ultra-reliable low latency communication (URLLC) SRS transmission).

[0081] In some aspects, the priority rules may indicate that when the SRS transmission is a priority 1 SRS transmission (e.g., an aperiodic SRS transmission), the UE 120 will avoid sending a PUSCH transmission (and will send an SRS transmission instead). For example, the UE 120 may discard (e.g., not send) symbols associated with a PUSCH transmission that overlaps or collides with an SRS transmission, as described herein. In some aspects, the priority rules may indicate that when the SRS transmission is a priority 2 SRS transmission (e.g., a semi-persistent SRS transmission or a periodic SRS transmission), the UE 120 will avoid sending an SRS transmission (and will send a PUSCH transmission instead).

[0082] Avoiding sending an SRS transmission may include discarding each symbol associated with the SRS transmission. In some aspects, avoiding sending an SRS transmission may include avoiding sending a second SRS transmission and discarding each symbol associated with the second SRS transmission. In some aspects, the UE 120 may determine that the second SRS transmission is to be discarded and the first SRS transmission is to be sent. For example, the SRS transmission may be associated with an additional purpose (e.g., codebook purpose, non-codebook purpose, beam management purpose, etc.). The UE 120 may determine that the second SRS transmission will not be sent (e.g., based at least in part on a priority rule, as described above) and may send the first SRS transmission for other purposes (e.g., in addition to antenna switching). For example, as described above, the first SRS transmission may be configured to use the same set of antenna ports (e.g., antenna ports 0 and 1) as the PUSCH transmission. Therefore, if the UE 120 does not send the second SRS transmission, the UE 120 does not have to perform antenna switching between the first SRS transmission and the PUSCH transmission. Therefore, the SRS transmission may not include a protection period and conflicts associated with the first SRS transmission and the PUSCH transmission may not occur.

[0083] As indicated by reference numeral 525, the base station 110 may determine an action to be performed by the UE 120 (e.g., whether the UE 120 is to send a PUSCH transmission or an SRS transmission) based at least in part on identifying the conflict in a manner similar to that described above with respect to the UE 120. For example, the base station 110 may apply one or more priority rules (e.g., the priority rules described above with respect to the UE 120) to determine whether the UE 120 is to avoid sending an SRS transmission (e.g., an entire SRS transmission, a second SRS transmission, etc.) or a PUSCH transmission.

[0084] As indicated by reference numeral 530, the UE 120 may send a PUSCH transmission or an SRS transmission based at least in part on determining whether to send a PUSCH transmission or an SRS transmission (e.g., based at least in part on one or more priority rules, as described above). In some aspects, the UE 120 may send only a PUSCH transmission. In some aspects, the UE 120 may send only an SRS transmission (e.g., a first SRS transmission, a second SRS transmission, etc.). In some aspects, the UE 120 may send a PUSCH transmission and a first SRS transmission (e.g., without sending a second SRS transmission).

[0085] As indicated by reference numeral 535, UE 120 may selectively receive a PUSCH transmission or an SRS transmission based at least in part on determining an action to be performed by UE 120 (e.g., based at least in part on determining that UE 120 is to send a PUSCH transmission or an SRS transmission). For example, base station 110 may determine that UE 120 is to forgo SRS transmission and send a PUSCH transmission. Base station 110 may receive the PUSCH transmission using resources allocated for PUSCH transmission. Similarly, base station 110 may receive the first SRS transmission using resources allocated for the first SRS transmission, and may receive the PUSCH transmission using resources allocated for PUSCH transmission.

[0086] Therefore, UE 120 and / or base station 110 can ensure that uplink communications are not corrupted or dropped, identify conflicts between protection periods of SRS transmissions and PUSCH transmissions, save network resources that would otherwise be used to send retransmissions of lost uplink communications, reduce delays in uplink transmissions, etc.

[0087] As mentioned above, providing Figure 5 As an example. Other examples may be related to Figure 5 Different than described.

[0088] Figure 6 is a diagram illustrating one or more examples 600 of collisions between SRS protection periods and PUSCH transmissions in accordance with the present disclosure.

[0089] like Figure 6 As shown, example 600 may include a first radio frame (e.g., frame 1) and a second radio frame (e.g., frame 2). The first radio frame and the second radio frame may be associated with the same component carrier (e.g., the same frequency) and / or different component carriers. The first radio frame and the second radio frame may be associated with the same time domain resources or different time domain resources. In some aspects, the first radio frame and the second radio frame may be associated with the same frame structure (e.g., the first radio frame may occur before the second radio frame in the time domain with the same frame structure).

[0090] like Figure 6 As shown, the first wireless frame and the second wireless frame may include one or more downlink time slots (e.g., where downlink communications may be scheduled), one or more uplink time slots (e.g., where uplink communications may be scheduled), and one or more special time slots (e.g., where downlink communications or uplink communications may be scheduled).

[0091] As described above, the SRS transmission may be configured to use resources of an uplink time slot or a special time slot. For example, as shown in the first radio frame, the SRS transmission may be configured with a first set of resources (e.g., for the first SRS transmission) and a second set of resources (e.g., for the second SRS transmission) in a special time slot. The second set of resources may include the last symbol of the special time slot (e.g., the second set of resources may be the last two symbols of the special time slot, as shown in the first radio frame). Figure 6 As described above, the first SRS transmission and the second SRS transmission may be associated with antenna switching purposes. Therefore, a plurality of symbols (eg, one symbol, such as Figure 6 Since the second group of SRS resources may include the last symbol of the special time slot, the protection period after the second group of SRS resources may occupy one or more symbols of the next time slot after the special time slot. Figure 5 As described, the PUSCH transmission may be scheduled in the time domain in an uplink time slot following the special time slot (e.g., such that one or more symbols of the PUSCH transmission include the first symbol of the uplink time slot directly following the special time slot). As a result, the guard period of the second set of SRS resources and the symbol allocated for the PUSCH transmission may overlap (e.g., the first symbol in the uplink time slot following the special time slot may be allocated for the PUSCH transmission and may be associated with the guard period of the second set of SRS resources). Therefore, the UE 120 may identify a conflict between the SRS guard period and the PUSCH transmission in the first radio frame. The UE 120 may determine whether to send a PUSCH transmission (e.g., as indicated by reference numeral 610) or an SRS transmission (e.g., as indicated by reference numeral 620) to mitigate the conflict, as described above according to Figure 5 described.

[0092] Similarly, as shown in the second radio frame, an SRS transmission can be configured in an uplink time slot. The SRS transmission can occupy symbols similar to those described above with respect to the special time slot and the first radio frame (e.g., the second set of SRS resources can include the last symbol of the uplink time slot). The second uplink time slot can be configured in the time domain directly after the uplink time slot including the SRS transmission. Similar to the uplink time slot described above with respect to the first radio frame, a PUSCH transmission can be scheduled in the second uplink time slot (e.g., such that one or more symbols of the PUSCH transmission include the first symbol of the second uplink time slot), and a protection period associated with the SRS transmission can include one or more symbols that include the first symbol of the second uplink time slot. Therefore, the UE 120 can identify a conflict between the SRS protection period and the PUSCH transmission in the second radio frame. The UE 120 can determine whether to send a PUSCH transmission (e.g., as shown in reference numeral 630) or an SRS transmission (e.g., as shown in reference numeral 640) to mitigate the conflict, as described above according to Figure 5 described.

[0093] As mentioned above, providing Figure 6 As an example. Other examples may be related to Figure 6 Different than described.

[0094] Figure 7 is a diagram illustrating an example process 700 performed, for example, by a UE in accordance with the present disclosure. Example process 700 is an example of operations performed by a UE (eg, UE 120) associated with collision handling for collisions between SRS protection periods and PUSCH transmissions.

[0095] like Figure 7 As shown, in some aspects, process 700 may include: identifying a conflict between a PUSCH transmission and a protection period of an SRS transmission, wherein the SRS transmission includes a first SRS transmission and a second SRS transmission, the second SRS transmission uses a first set of one or more antenna ports of the UE, and the PUSCH transmission uses a second set of one or more antenna ports of the UE (block 710). For example, the UE (e.g., using the receive processor 258, the transmit processor 264, the controller / processor 280, the memory 282, etc.) may identify a conflict between the PUSCH transmission and the protection period of the SRS transmission, as described above. In some aspects, the SRS transmission includes a first SRS transmission and a second SRS transmission, the second SRS transmission uses a first set of one or more antenna ports of the UE, and the PUSCH transmission uses a second set of one or more antenna ports of the UE. In some aspects, the UE may identify a conflict between the PUSCH transmission and the protection period of the SRS transmission based at least in part on resources associated with the PUSCH transmission and resources associated with the protection period.

[0096] like Figure 7 As further shown in FIG. 7 , in some aspects, process 700 may include: performing actions to mitigate the conflict based at least in part on identifying the conflict (block 720). For example, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may perform actions to mitigate the conflict based at least in part on identifying the conflict, as described above.

[0097] Process 700 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.

[0098] In a first aspect, the PUSCH transmission and the SRS transmission are configured to be sent on the same component carrier.
