Description

Technical Field

[0001] Generally speaking, the following relates to wireless communication, and more specifically, the following relates to reference signal transmission omission and postponement. Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcasting, etc. These systems are capable of supporting communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multi-access systems include fourth-generation (4G) systems (e.g., Long-Term Evolution (LTE) systems, enhanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems may employ technologies such as the following: Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multi-access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication for multiple communication devices (which may also be referred to as User Equipment (UE)). Summary of the Invention

[0003] The described technology relates to improved methods, systems, devices, and apparatuses that support reference signal transmission omission and postponement. Generally speaking, the described technology provides various mechanisms for determining whether to omit or delay one or more conflicting reference signal transmissions. For example, a base station may configure a User Equipment (UE) with a set of reference signal transmissions (e.g., an aperiodic sounding reference signal (SRS) resource configuration configured via Radio Resource Control (RRC) signaling). The base station and / or the UE may determine that there is a resource overlap for one or more of the reference signals in the set of reference signal transmissions. For example, the base station and / or the UE may determine that one or more symbols in the set of reference signal transmissions are configured for downlink transmission or flexible transmission, are allocated to another uplink channel with a higher priority compared to the reference signal transmission, are allocated as guard symbols, are allocated for measurement gaps / Radio Frequency (RF) retuning gaps, and / or are otherwise configured to be unavailable via implicit and / or explicit signaling.

[0004] Then, the UE and / or the base station can identify one or more transmission attributes of a reference signal transmission set. Examples of transmission attributes of a reference signal transmission can include, but are not limited to, the length of the reference signal transmission set, the ratio of resource overlap of the reference signal transmission set, the usage of the reference signal transmission set, the location of resource overlap within the reference signal transmission set, the interleaving configuration for the reference signal transmission set, and / or the repetition configuration for the reference signal transmission set. The base station and / or the UE (e.g., to ensure consistency between devices) can consider resource overlap and transmission attributes when determining whether to omit one or more reference signal transmissions in the reference signal transmission that occurs in the corresponding resource overlap or delay the transmission of the reference signal transmission set (e.g., delay to a later time slot). When determining whether to omit conflicting reference signal transmissions or delay the transmission of the reference signal transmission set, the transmission attributes and / or the nature of the resource overlap can be considered individually, jointly, or in any combination. Thus, the UE can send (and the base station can receive) at least a portion of the reference signal transmission set based on the omission / delay determination. For example, the UE can send the non-omitted reference signal transmissions during the configured time slot, or can delay sending all of the reference signal transmission set until a later time slot.

The method can include: receiving a configuration signal that configures a reference signal transmission set; identifying a resource overlap between the reference signal transmission set and another resource that is not available for reference signal transmission; identifying one or more transmission attributes of the reference information transmission set; determining whether to omit one or more reference signal transmissions in the reference signal transmission set that occurs in the corresponding resource overlap or delay the transmission of the reference information transmission set based on the one or more transmission attributes and the resource overlap; and sending at least a portion of the reference signal transmission set based on the determination.

[0070] A wireless communication system can use reference signals transmitted by a user equipment (UE) and / or a base station for various purposes. An example of such a reference signal includes a sounding reference signal (SRS). An SRS resource set (e.g., a set of reference signal transmissions) can include a set of SRS resources transmitted by one UE. The SRS resource set can be transmitted aperiodically (e.g., signaled using downlink control information (DCI)), semi-persistently (e.g., signaled using radio resource control (RRC)), or periodically (e.g., also signaled using RRC). The UE can be configured with multiple resources, which can be grouped into SRS resource sets according to use cases (e.g., antenna switching, codebook-based, non-codebook-based, beam management, etc.). However, in some cases, one or more of the resources in the SRS resource set (e.g., at least one reference signal transmission within the set of reference signal transmissions) may conflict or otherwise be unavailable for the UE to perform reference signal transmission. Although no definite rules have been established to resolve such a situation, a general approach adopted in some wireless communication systems can simply make aperiodic SRSs take precedence over semi-persistent SRSs, and make semi-persistent SRSs take precedence over periodic SRSs. However, this approach limits the availability of the configured SRS resource set for the UE and / or the base station, which results in a significant waste of resources and miscommunication between the base station and the UE (e.g., the UE and the base station may be out of sync regarding the actually transmitted reference signal).

[0071] Aspects of the present disclosure are first described in the context of a wireless communication system. Generally speaking, the described techniques provide various mechanisms for determining whether to omit or delay one or more conflicting reference signal transmissions. For example, the base station can configure the UE with a set of reference signal transmissions (e.g., an aperiodic SRS resource configuration configured via RRC signaling). The base station and / or the UE can determine that there is a resource overlap regarding one or more reference signal transmissions among the reference signals in the reference signal transmission set. For example, the base station and / or the UE can determine that one or more symbols in the reference signal transmission set are configured for downlink or flexible transmission, are allocated to another uplink channel with a higher priority than the reference signal transmission, are allocated as guard symbols, are allocated for measurement gaps / radio frequency (RF) retuning gaps, and / or are otherwise configured to be unavailable through implicit and / or explicit signaling.

[0072] Then, the UE and / or the base station can identify one or more transmission attributes of a reference signal transmission set. Examples of the transmission attributes of the reference signal transmission can include, but are not limited to, the length of the reference signal transmission set, the ratio of resource overlap of the reference signal transmission set, the use of the reference signal transmission set, the location of resource overlap within the reference signal transmission set, the interleaving configuration for the reference signal transmission set, and / or the repetition configuration for the reference signal transmission set. The base station and / or the UE (e.g., to ensure consistency between devices) can consider resource overlap and transmission attributes when determining whether to omit one or more reference signal transmissions that occur in the corresponding resource overlap or delay the transmission of the reference signal transmission set (e.g., delay to a later time slot). When determining whether to omit conflicting reference signal transmissions or delay the transmission of the reference signal transmission set, the transmission attributes and / or the nature of the resource overlap can be considered individually, jointly, or in any combination. Thus, the UE can send (and the base station can receive) at least a portion of the reference signal transmission set based on the omission / delay determination. For example, the UE can send the non-omitted reference signal transmissions during the configured time slot, or can delay sending the entire reference signal transmission set until a later time slot.

[0073] Aspects of the present disclosure are further illustrated by apparatus diagrams, system diagrams, and flowcharts that pertain to reference signal transmission omission and deferral, and aspects of the present disclosure are described with reference to these diagrams.

In some examples, the wireless communication system 100 can be a Long Term Evolution (LTE) network, an enhanced LTE (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 can support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices, or any combination thereof.

[0075] Base stations 105 can be spread across an entire geographical area to form a wireless communication system 100 and can be devices of different forms or with different capabilities. The base stations 105 and the UEs 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and the UEs 115 and the base stations 105 can establish one or more communication links 125 over the coverage area 110. The coverage area 110 can be an example of such a geographical area over which the base stations 105 and the UEs 115 can support the transmission of signals according to one or more radio access technologies.

[0076] The UEs 115 can be spread across the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, or mobile, or both at different times. The UEs 115 can be devices of different forms or with different capabilities. Some example UEs 115 are shown in Figure 1 . The UEs 115 described herein are capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), as Figure 1 shown.

[0077] The base stations 105 can communicate with the core network 130, or with each other, or both. For example, the base stations 105 can interface with the core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). The base stations 105 can communicate directly (e.g., directly between base stations 105) with each other, or indirectly (e.g., via the core network 130) with each other, or both, over the backhaul links 120 (e.g., via X2, Xn, or other interfaces). In some examples, the backhaul links 120 can be or include one or more wireless links.

[0078] One or more of the base stations 105 described herein can include or can be referred to by those skilled in the art as a base station transceiver, radio base station, access point, radio transceiver, Node B, evolved Node B (eNB), next generation Node B, or Gigabit Node B (any of which can be referred to as a gNB), home Node B, home evolved Node B, or some other suitable term.

[0079] The UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where the "device" may also be referred to as a unit, a station, a terminal, or a client, among other examples. The UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, the UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, among other examples, which may be implemented in various items such as appliances, or vehicles, meters, and other examples.

[0080] The UE 115 described herein is capable of communicating with various types of devices, such as other UE 115s that may sometimes act as relays, as well as base station 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as Figure 1 shown.

[0081] The UE 115 and the base station 105 may communicate wirelessly with each other over one or more carriers via one or more communication links 125. The term "carrier" may refer to a collection of radio frequency spectrum resources having a defined physical layer structure for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth part (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating the operation of the carrier, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. According to a carrier aggregation configuration, the UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0082] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates operations for other carriers. A carrier may be associated with a frequency channel (e.g., an evolved universal mobile telecommunications system terrestrial radio access (E-UTRA) absolute radio frequency channel number (EARFCN)) and may be placed according to a channel raster so as to be discovered by UE 115. A carrier may operate in stand-alone mode, where UE 115 performs initial acquisition and connection via the carrier, or the carrier may operate in non-stand-alone mode, where a different carrier (e.g., of the same or different radio access technology) is used to anchor the connection.

[0083] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from UE 115 to the base station 105 or a downlink transmission from the base station 105 to UE 115. A carrier may carry downlink or uplink communication (e.g., in FDD mode) or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0084] A carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or the wireless communication system 100. For example, the carrier bandwidth may be one of a number of defined bandwidths for a carrier of a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) may have a hardware configuration that supports communication on a particular carrier bandwidth or may be configurable to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a sub-band, BWP) or all of the carrier bandwidth.

[0085] The signal waveform transmitted on a carrier can be composed of multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread spectrum OFDM (DFT-S-OFDM)). In a system adopting the MCM technique, a resource element can include a symbol period (e.g., the duration of a modulated symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements received by the UE 115 and the higher the order of the modulation scheme, the higher the data rate for the UE 115 can be. Wireless communication resources can refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity for communication with the UE 115.

[0086] One or more numerologies for a carrier can be supported, where a numerology can include a subcarrier spacing (Δf) and a cyclic prefix. The carrier can be divided into one or more BWPs with the same or different numerologies. In some examples, the UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and the communication for the UE 115 can be restricted to one or more active BWPs.

[0087] The time intervals for the base station 105 or the UE 115 can be represented as multiples of a basic time unit, which can, for example, refer to a sampling period of T s = 1 / (Δf max ·N f ) seconds, where Δf max can represent the maximum supported subcarrier spacing, and N f can represent the maximum supported discrete Fourier transform (DFT) size). The time intervals of the communication resources can be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0088] Each frame may include a plurality of consecutively numbered sub - frames or time slots, and each sub - frame or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into sub - frames, and each sub - frame may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the sub - carrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix added in front of each symbol period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini - slots each containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N f

[0089]

[0090]

[0091] sub - frames, time slots, mini - slots, or symbols may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in the form of a burst of shortened TTIs (sTTIs)).

[0091] Physical channels may be multiplexed on a carrier according to various techniques. For example, time - division multiplexing (TDM) techniques, frequency - division multiplexing (FDM) techniques, or one or more of hybrid TDM - FDM techniques may be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by the number of symbol periods and may extend across the system bandwidth of the carrier or a subset of the system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a group of UEs 115. For example, one or more of the UEs 115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates at one or more aggregation levels arranged in a cascaded manner. The aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information for a control information format having a given payload size. The search space set may include a common search space set configured to send control information to a plurality of UEs 115 and a UE - specific search space set for sending control information to a particular UE 115.

[0091] Each base station 105 can provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" can refer to a logical communication entity for communicating with the base station 105 (e.g., on a carrier), and can be associated with an identifier for distinguishing adjacent cells (e.g., physical cell identifier (PCID), virtual cell identifier (VCID), or other identifier). In some examples, a cell can also refer to a geographic coverage area 110 or a portion of the geographic coverage area 110 (e.g., a sector) on which the logical communication entity operates. Depending on various factors (such as the capabilities of the base station 105), the scope of such a cell can range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell can be or include a building, a subset of a building, or an external space between or overlapping with the geographic coverage areas 110, and other examples.

[0092] Macro cells typically cover a relatively large geographic area (e.g., with a radius of several kilometers) and can allow unrestricted access by UEs 115 having a service subscription with the network provider that supports the macro cell. Compared with macro cells, small cells can be associated with lower-power base stations 105, and small cells can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UEs 115 having a service subscription with the network provider, or can provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed user group (CSG), UEs 115 associated with users in a residence or office). The base station 105 can support one or more cells and can also support communication on one or more cells using one or more component carriers.

[0093] In some examples, a carrier can support multiple cells and can be configured with different cells according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that can provide access for different types of devices.

[0094] In some examples, the base station 105 can be movable, and thus, provide communication coverage for a moving geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, but different geographic coverage areas 110 can be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies can be supported by different base stations 105. The wireless communication system 100 can include, for example, a heterogeneous network, where different types of base stations 105 use the same or different radio access technologies to provide coverage for respective geographic coverage areas 110.

[0095] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, the base stations 105 can have similar frame timings, and transmissions from different base stations 105 can be approximately aligned in time. For asynchronous operation, the base stations 105 can have different frame timings, and in some examples, transmissions from different base stations 105 can not be aligned in time. The techniques described herein can be used for synchronous or asynchronous operation.

[0096] Some UEs 115 (e.g., MTC or IoT devices) can be low-cost or low-complexity devices, and can provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with the base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices integrated with sensors or meters to measure or capture information and relay such information to a central server or application that utilizes the information or presents the information to a human who interacts with the application. Some UEs 115 can be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, device monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business billing.

[0097] Some UEs 115 may be configured to operate in a power-reduced mode of operation, e.g., half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception rather than simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power saving techniques for the UE 115 include entering a power-saving deep sleep mode when not participating in active communication, when operating on a limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UEs 115 may be configured for operation using a narrowband protocol type associated with a defined portion or extent (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of the carrier, or external to the carrier.

[0098] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. The UE 115 may be designed to support ultra-reliability, low latency, or critical functions (e.g., mission-critical functions). Ultra-reliable communication may include private communication or group communication and may be supported by one or more mission-critical services such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData). Support for mission-critical functions may include prioritization of services, and mission-critical services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency may be used interchangeably herein.

[0099] In some examples, the UE 115 is capable of communicating directly with other UEs 115 over the D2D communication link 135 (e.g., using a peer-to-peer (P2P) or device-to-device (D2D) protocol). One or more UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105 or otherwise unable to receive transmissions from the base station 105. In some examples, groups of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, where each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without involving the base station 105.

[0100] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. Vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information related to the V2X system. In some examples, vehicles in a V2X system can communicate with roadside infrastructure (such as a roadside unit), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or perform both operations.

[0101] The core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), which can include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes packets to or interconnects with an external network (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for a UE 115 served by a base station 105 associated with the core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can be connected to a network operator IP service 150. The operator IP service 150 can include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet-switched streaming service.

[0102] Some network devices in the network (e.g., base station 105) can include subcomponents such as an access network entity 140, which can be an example of an access node controller (ANC). Each access network entity 140 can communicate with a UE 115 through one or more other access network transmission entities 145 (which can be referred to as a radio head, a smart radio head, or a transmit / receive point (TRP)). Each access network transmission entity 145 can include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 can be distributed across various network devices (e.g., radio head and ANC) or combined into a single network device (e.g., base station 105).

[0103] The wireless communication system 100 may operate using one or more frequency bands (generally, in the range of 300 megahertz (MHz) to 300 gigahertz (GHz)). Generally, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or the decimeter band because the wavelength range is from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves may be sufficient to penetrate structures for a macro cell to serve a UE 115 located indoors. Compared to transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmissions may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers).

[0104] The wireless communication system 100 may also operate in the super-high frequency (SHF) region using frequency bands from 3 GHz to 30 GHz (also referred to as the centimeter band) or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as the millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding devices may be even smaller and more closely spaced compared to UHF antennas. In some examples, this may facilitate the use of antenna arrays within the device. However, EHF transmissions may suffer from even greater atmospheric attenuation and shorter distances compared to SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the designation of the use of frequency bands across these frequency regions may vary according to the country or regulatory body.

[0105] The wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may employ licensed-assisted access (LAA), LTE-unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed frequency band such as the 5 GHz industrial, scientific, and medical (ISM) band. When operating in an unlicensed radio frequency spectrum band, devices (such as the base station 105 and the UE 115) may employ carrier sensing for collision detection and avoidance. In some examples, operation in an unlicensed frequency band may be based on a carrier aggregation configuration that combines a component carrier operating in a licensed frequency band (e.g., LAA). Operations in the unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer (P2P) transmissions, or device-to-device (D2D) transmissions, among other examples.

[0106] The base station 105 or the UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the base station 105 or the UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operation or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with the base station 105 may be located at different geographical locations. The base station 105 may have an antenna array having a number of rows and columns of antenna ports that the base station 105 may use to support beamforming for communication with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0107] The base station 105 or the UE 115 may use MIMO communication to take advantage of multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. For example, a transmitting device may transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device may receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) (where multiple spatial layers are transmitted to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are transmitted to multiple devices).

[0108] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., base station 105, UE 115) to form or direct an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals transmitted via the antenna elements of an antenna array such that some signals propagating in a particular orientation relative to the antenna array experience constructive interference while other signals experience destructive interference. Adjusting the signals transmitted via the antenna elements can include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to the signals carried via the antenna elements associated with the device. The adjustment associated with each of the antenna elements can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0109] As part of the beamforming operation, the base station 105 or the UE 115 can use beam scanning techniques. For example, the base station 105 can use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. The base station 105 can transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, the base station 105 can transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions can be used (e.g., by the transmitting device such as the base station 105 or by the receiving device such as the UE 115) to identify the beam direction for subsequent transmissions or receptions performed by the base station 105.

[0110] The base station 105 can transmit some signals (e.g., data signals associated with the receiving device) in a single beam direction (e.g., the direction associated with a particular receiving device (e.g., UE 115)). In some examples, the beam direction associated with the transmission along a single beam direction can be determined based on signals transmitted in one or more beam directions. For example, the UE 115 can receive one or more of the signals transmitted by the base station 105 in different directions and can report to the base station 105 an indication of the signal that has the highest signal quality or otherwise acceptable signal quality received by the UE 115.

[0111] In some examples, multiple beam directions may be used to perform transmissions by a device (e.g., by base station 105 or UE 115), and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from base station 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured number of beams across the system bandwidth or one or more subbands. Base station 105 may transmit reference signals that may or may not be precoded (e.g., cell-specific reference signal (CRS), channel state information reference signal (CSI-RS)). UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., for identifying beam directions for subsequent transmissions or receptions by UE 115) or to transmit signals in a single direction (e.g., for transmitting data to a receiving device).

[0112] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, a receiving device (e.g., UE 115) may attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device may receive by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by receiving according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of an antenna array (e.g., different sets of directional listening weights), or by processing received signals according to different sets of receive beamforming weights applied to signals received at multiple antenna elements of an antenna array (any of the above operations may be referred to as "listening" according to different receiving configurations or receiving directions), thereby attempting multiple receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). The single receiving configuration may be aligned in a beam direction determined based on listening according to different receiving configuration directions (e.g., a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening according to multiple beam directions).

[0113] The wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication at the bearer or packet data convergence protocol (PDCP) layer can be IP-based. The radio link control (RLC) layer can perform packet segmentation and reassembly for transmission over logical channels. The medium access control (MAC) layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmission at the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide the establishment, configuration, and maintenance of an RRC connection (which supports radio bearers for user plane data) between the UE 115 and the base station 105 or the core network 130. At the physical layer, transport channels can be mapped to physical channels.

[0114] The UE 115 and the base station 105 can support retransmission of data to increase the likelihood that the data is successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood that data is correctly received over the communication link 125. HARQ can include a combination of error detection (e.g., using cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve throughput at the MAC layer in poor radio conditions (e.g., low signal-to-noise conditions). In some examples, the device can support same-slot HARQ feedback, where the device can provide HARQ feedback for data received in previous symbols in a particular slot in that slot. In other cases, the device can provide HARQ feedback in a subsequent slot or according to some other time interval.

[0115] The UE 115 can receive a configuration signal that configures a set of reference signal transmissions. The UE 115 can identify a resource overlap between the set of reference signal transmissions and another resource that is not available for reference signal transmission. The UE 115 can identify one or more transmission attributes of the reference information transmission set. The UE 115 can determine whether to omit one or more reference signal transmissions in the set of reference signal transmissions in the corresponding resource overlap or delay the transmission of the reference information transmission set at least in part based on the one or more transmission attributes and the resource overlap. The UE 115 can transmit at least a portion of the set of reference signal transmissions at least in part based on the determination.

[0116] Base station 105 may send a configuration signal that configures a set of reference signal transmissions to UE 115. The base station 105 may identify a resource overlap between the set of reference signal transmissions and another resource that is not available for reference signal transmission. The base station 105 may identify one or more transmission attributes of the reference information transmission set. The base station 105 may determine, at least in part, based on the one or more transmission attributes and the resource overlap, whether to omit one or more reference signal transmissions in the set of reference signal transmissions in the corresponding resource overlap or delay the transmission of the reference information transmission set. The base station 105 may receive at least a portion of the set of reference signal transmissions, at least in part, based on the determination.

[0117] Figure 2 An example of a wireless communication system 200 that supports reference signal transmission omission and postponement in accordance with aspects of the present disclosure is shown. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. The wireless communication system 200 may include a base station 205 and a UE 210, which may be examples of the corresponding devices described herein. In some aspects, the wireless communication system 200 may be an example of an NR / 5G wireless communication system.

[0118] The wireless communication system 200 may support configured SRS resources (e.g., resources allocated for an SRS burst within a time slot), which span one, two, or four adjacent symbols within a time slot, with up to four ports per SRS resource. All ports of the SRS resource may be probed in each symbol. SRS transmissions may occur in the last six symbols of a time slot (such as time slot 215), where symbols 8 to 13 are SRS transmission opportunities 220. SRS transmissions typically occur after an uplink data channel (e.g., PUSCH) in a time slot. An SRS resource set may include SRS resources transmitted by a UE (such as UE 210). The SRS resource set may be transmitted aperiodically (e.g., via a DCI signal), semi-persistently, or periodically. A UE may be configured with multiple SRS resources, which may be grouped into SRS resource sets according to use cases (e.g., antenna switching, codebook-based versus non-codebook-based, beam management, etc.). SRS transmissions may be broadband / sub-band configured. For example, the SRS bandwidth may be a multiple of four physical resource blocks (PRBs).

[0119] In some aspects, the handling of conflicts between two aperiodic SRS resource sets can be implementation - specific. For example, there are no established rules on how to handle such situations. Regarding other SRS configurations, aperiodic SRS resource sets are generally given a higher priority compared to semi - persistent SRS resource sets, and semi - persistent SRS resource sets are given a higher priority compared to periodic SRS resource sets. As an example, in the case where an SRS resource with an aperiodic SRS resource type is triggered on an OFDM symbol that is also configured with periodic / semi - persistent SRS transmission, the UE can transmit the aperiodic SRS resource and not transmit the periodic / semi - persistent SRS resource that overlaps within the symbol. As another example, in the case where an SRS resource with a semi - persistent SRS resource type is triggered on an OFDM symbol that is configured with periodic SRS transmission, the UE can transmit the semi - persistent SRS resource and not transmit the periodic SRS resource that overlaps within the symbol.

[0120] The triggering of an aperiodic SRS resource can utilize two bits in the DCI, where each configured aperiodic SRS resource set is marked as "1" or "2" or "3" in the DCI. Each aperiodic SRS resource set can be configured with a slot offset from 0 to 32. The slot offset is the offset (in number of slots) between the triggering DCI and the actual transmission of the aperiodic SRS resource set. If this field does not exist (e.g., is blank or set to a zero value), the UE does not apply an offset between the triggering DCI and the transmission of the aperiodic SRS resource set. Each SRS resource of an aperiodic SRS resource set can have an associated symbol index (e.g., start position) that includes the first symbol of the SRS resource. An aperiodic SRS resource set can span multiple consecutive OFDM symbols, e.g., one, two, four, etc. symbols.

[0121] Some wireless communication systems have considered SRS postponement. For example, if at least one symbol in the symbols of the SRS resource set in the configured slot offset is not available for SRS transmission, the SRS resource set is postponed to a later slot. This can be configured based on the slot type, such as downlink, uplink, or flexible. For example, if the symbol is configured as a downlink symbol or a flexible symbol in which a downlink physical channel has been triggered for transmission, the symbol may not be available for SRS transmission, and the SRS resource set can be postponed by Δ slots, where Δ is the slot offset. The maximum number of slots by which an aperiodic SRS resource set can be postponed (e.g., the maximum value of Δ) is also considered, after which the SRS resource set is considered to have been discarded. Examples of the maximum number of slots include, but are not limited to: Δ is specified as a fixed value for all numerology schemes (e.g., 5 slots), different specified values for each numerology scheme (e.g., 5 slots for 15 kHz subcarrier spacing (SCS), but 10 slots for 30 kHz SCS), specifying an absolute duration (e.g., 3 ms), configurable for each SRS resource set (e.g., at the RRC level), can be different for different use cases of the SRS resource set (e.g., for an antenna switching set, Δ can be 5, but for an uplink codebook or non-codebook or uplink beam management set, Δ can be equal to 0), etc. The maximum number of postponed slots can be equal to the maximum slot offset that has been configured for the SRS resource set and / or the maximum postponed slot can be equal to the maximum slot offset that can be configured for any SRS resource set (e.g., up to 32 slots).

[0122] While such methods may be applicable in some cases, these methods limit the ability of the base station 205 and / or the UE 210 to more dynamically determine whether to postpone the SRS resource set or can omit the conflicting OFDM symbols within the SRS resource set (e.g., symbols that are otherwise not available for SRS transmission), while maintaining the ability to perform SRS transmission within other symbols (e.g., non-conflicting symbols). These methods may cause the SRS transmission within the resource set to be postponed unnecessarily, which may waste resources, disrupt the communication between the base station 205 and the UE 210 (e.g., create a misunderstanding between the base station 205 and the UE 210 regarding whether a particular SRS transmission will occur), etc.

[0123] Accordingly, aspects of the described techniques provide mechanisms for determining whether to defer (e.g., delay) an SRS resource set (e.g., a set of reference signal transmissions, which may also be referred to as an SRS burst) or omit one or more reference signal transmissions in a corresponding resource overlap (e.g., discard a reference signal transmission in a symbol not available for reference signal transmission). That is, aspects of the described techniques provide various mechanisms for determining whether to omit one or more conflicting reference signal transmissions (e.g., SRS transmissions) or defer an SRS resource set. For example, base station 205 may configure UE 210 with a set of reference signal transmissions (e.g., an aperiodic SRS resource set or SRS burst configured via RRC signaling). Base station 205 and / or UE 210 may determine that there is a resource overlap with respect to one or more reference signal transmissions in the set of reference signal transmissions. For example, base station 205 and / or UE 210 may determine that one or more symbols in the set of reference signal transmissions are configured for downlink transmission or flexible transmission, are allocated to another uplink channel having a higher priority than the reference signal transmission, are allocated as guard symbols, are allocated for a measurement gap / RF retuning gap, and / or are otherwise configured as not available for reference signal transmission via implicit and / or explicit signaling from base station 205.

[0124] Then, UE 210 and / or base station 205 may identify one or more transmission attributes of the set of reference signal transmissions. Base station 205 and / or UE 210 (e.g., to ensure consistency between devices) may consider the resource overlap and the transmission attributes when determining whether to omit one or more reference signal transmissions that occur in the corresponding resource overlap or defer the transmission of the set of reference signal transmissions (e.g., delay to a later time slot). The transmission attributes and / or the nature of the resource overlap may be considered individually, jointly, or in any combination when determining whether to omit a conflicting reference signal transmission or defer the transmission of the set of reference signal transmissions. Accordingly, UE 210 may transmit (and base station 205 may receive) at least a portion of the set of reference signal transmissions based on the omit / delay determination. For example, UE 205 may transmit the non-omitted reference signal transmissions during the configured time slot 215, or may defer transmitting the entire set of reference signal transmissions until a later time slot (e.g., Δ).

[0125] That is, determining whether to delay or discard an aperiodic SRS (e.g., one or more reference signal transmissions from a set of reference signal transmissions) when one or more symbols conflict with one or more symbols not available for SRS transmission may depend on the transmission attributes of the aperiodic SRS resource set, e.g., the transmission attributes of the set of reference signal transmissions and the nature of the resource overlap. The base station 205 may explicitly and / or implicitly configure any one of the transmission attributes and / or their corresponding threshold levels / weighting factors for the UE 210. Additionally, when making this determination, a higher or lower priority may be assigned to any transmission attribute compared to other transmission attributes. Further, the UE 210 may send a UE capability message to the base station 205, which carries or conveys an indication that the UE 210 supports delaying or discarding a reference signal transmission based on transmission attributes, resource overlap, etc. Thus, the base station 205 may configure the UE 210 with transmission attributes, corresponding thresholds for the transmission attributes, and / or priorities / weighting factors via a configuration signal (e.g., an RRC signal).

[0126] In one example of a transmission attribute, the base station 205 and / or the UE 210 may identify the length of the set of reference signal transmissions as one of the transmission attributes. This may include identifying the number of symbols configured for reference signal transmission (e.g., the number of symbols actually configured for reference signal transmission within the time slot 215). This may include determining that the number of symbols configured for reference signal transmission is less than a threshold. The base station 205 and / or the UE 210 may determine to delay the transmission of the set of reference signal transmissions based on the number of symbols being less than the threshold. The base station 205 may configure the UE with a threshold for the number of symbols configured for reference signal transmission.

[0127] That is, if the SRS resource set has a length spanning a large number of symbols, but only one or two symbols conflict (e.g., are not available for reference signal transmission), then the base station 205 and / or the UE 210 may determine to omit these symbols and send the remaining reference signal transmissions during other symbols (e.g., non-conflicting symbols available for reference signal transmission). This may be based on the fact that since most of the SRS resource set can still be transmitted, it may be more beneficial to use these configured resources for reference signal transmission. However, if the SRS resource set is a small number of symbols (e.g., one or two symbols), then the base station 205 and / or the UE 210 may postpone the entire transmission in the SRS resource set (e.g., may postpone sending the set of reference signal transmissions). Thus, the threshold may indicate that for a length <X, if at least one symbol conflicts, then postpone the entire SRS resource. Otherwise, the conflicting symbols may be omitted, and the remaining symbols may be sent.

[0128] In another example of a transmission attribute, the base station 205 and / or the UE 210 may identify the ratio of a first length of resource overlap to a second length of a reference signal transmission set as one of the transmission attributes. For example, the base station 205 and / or the UE 210 may identify the number of symbols configured for reference signal transmission (e.g., the second length) and the number of unavailable symbols within the symbols configured for reference signal transmission (e.g., the first length). If the number of symbols configured for reference signal transmission is less than a first threshold, the base station 205 and / or the UE 210 may determine to delay the transmission of the reference signal transmission set. However, if the number of symbols configured for reference signal transmission meets the first threshold and the number of unavailable symbols is less than a second threshold, the base station 205 and / or the UE 210 may omit the reference signal transmission in the corresponding resource overlap. That is, the decision may depend on a threshold according to the following equation (number of conflicting or unavailable symbols / length or number of symbols of the SRS resource set) < X. In a non-limiting example, if the set of reference signal transmissions spans one or two symbols and at least one of these symbols is unavailable, it may be more beneficial to delay the reference signal transmission. In another non-limiting example, if the set of reference signal transmissions spans four symbols but only one of these symbols is unavailable, it may be more beneficial to omit the unavailable symbol and send the reference signal transmission in the remaining symbols.

[0129] In another example of a transmission attribute, the base station 205 and / or the UE 210 may identify the use of a reference signal transmission set. For example, if the reference signal transmission is a positioning reference signal transmission, the base station 205 and / or the UE 210 may delay the transmission of the reference signal transmission set. That is, the use / purpose of the SRS resource set (e.g., the reference signal transmission set) may be considered when determining whether to delay or omit the transmission. For SRS transmissions for positioning, omitting one or more symbols may result in a partially transmitted and partially interleaved SRS resource. This may create false signals / false picks in the time of arrival (TOA) estimation. Therefore, for SRSs for positioning, it may always be more beneficial to delay or postpone the reference signal transmission even if only one symbol is a conflicting symbol or otherwise unavailable for reference signal transmission. Depending on the different use cases of the reference signal transmission, other rules for determining whether to omit or delay may also apply. In addition, the thresholds for the length and / or ratio of the conflicting symbols (e.g., as described above) may also be specific to the use / purpose.

[0130] In another example of transmission properties, the base station 205 and / or the UE 210 can identify locations where there is resource overlap within a set of reference signal transmissions. For example, if the resource overlap occurs between a first set of symbols and a second set of symbols that are configured for reference signal transmission (e.g., somewhere in the middle of an SRS resource set), then the base station 205 and / or the UE 210 can determine to delay the transmission of the set of delayed reference signals. However, if the resource overlap occurs during the start symbol or the end symbol that is configured for reference signal transmission, then the base station 205 and / or the UE 210 can omit the reference signal transmission in the corresponding resource overlap. That is, the base station 205 and the UE 210 can determine the position of the conflicting SRS symbols (e.g., unavailable symbols) relative to the SRS burst (e.g., the set of reference signal transmissions in the symbols available for reference signal transmission). If the conflicting symbols are in the middle of the burst, there is no guarantee of phase continuity between the first part and the second part of the remaining SRS burst. Therefore, it may be more beneficial to completely postpone or delay the SRS resource set. On the other hand, if the conflicting symbols are at the start or end of the SRS burst, the remaining non-conflicting SRS burst will still be phase continuous, and it may be more beneficial to omit the conflicting symbols.

[0131] In another example of transmission properties, the base station 205 and / or the UE 210 can identify an interleaved configuration for a set of reference signal transmissions. If the reference signal transmission is configured for interleaved transmission, then the base station 205 and / or the UE 210 can delay the transmission of the set of reference signals, or if the set of reference signal transmissions is configured for non-interleaved transmission, then the base station 205 and / or the UE 210 can omit the reference signal transmission in the corresponding resource overlap. That is, if the SRS resource set is configured with interleaving, omitting one or more symbols may result in a partially transmitted partially interleaved SRS resource. This may create false signals / false pickups in TOA estimation. Therefore, even if only one symbol conflicts, it may always be more beneficial to postpone the transmission of the set of reference signal transmissions. These rules can apply to any other SRS resource set that is not configured with interleaving. In some aspects, as described above, the threshold for the length or ratio of the conflicting symbols can depend on whether interleaving is configured.

[0132] In another example of transmission attributes, the base station 205 and / or the UE 210 may identify a repetition configuration for a set of reference signal transmissions. If the reference signal transmission is configured for repeated transmission across multiple time slots, the base station 205 and / or the UE 210 may omit the reference signal transmission in the corresponding resource overlap. That is, if the SRS resource is configured with repetition across multiple time slots, the postponement may cause the postponement of the second, third, etc. parts (e.g., repetitions) in subsequent time slots. This may create higher complexity for the UE's statistics of SRS transmissions. Therefore, if the SRS transmission is configured across multiple time slots, the base station 205 and / or the UE 210 may omit the conflicting symbols, but transmit the reference signal transmission in the remaining symbols.

[0133] As described above, when determining whether to delay or omit the reference signal transmission, the base station 205 and / or the UE 210 may individually or in any combination utilize the resource overlap (e.g., the number and / or location of conflicting symbols) and any transmission attributes. The base station 205 may send a configuration signal to the UE 210 that identifies which transmission attributes to utilize and their associated threshold levels and / or weighting factors. The base station 205 may configure the UE 210 with transmission attributes based on the capabilities of the UE 210 (e.g., as indicated in the UE capability message). The UE 210 may utilize the transmission attributes and the nature of the resource overlap when making the delay / omit determination, and the base station 205 may utilize the same transmission attributes or the nature of the resource overlap when determining whether the UE 210 will delay or omit the associated reference signal transmission.

[0134] Figure 3 An example of a method 300 that supports reference signal transmission omission and postponement in accordance with aspects of the present disclosure is shown. In some examples, the method 300 may implement aspects of the wireless communication systems 100 and / or 200. Aspects of the method 300 may be implemented by a UE and / or a base station (which may be examples of the corresponding devices described herein).

[0135] At 305, the base station may configure the UE with a set of reference signal transmissions (e.g., an SRS resource set on which SRS transmissions or SRS bursts may occur) for the UE to transmit in consecutive symbols within one or more time slots. For example, the base station may send an RRC signal to the UE that configures the UE with the set of reference signal transmissions. In some examples, the set of reference signal transmissions may be configured with or without interleaving and / or repetition. The set of reference signal transmissions may include an aperiodic SRS resource that spans one or more consecutive symbols within a time slot.

[0136] At 310, the base station and / or the UE may identify a resource overlap between a reference signal transmission set and another resource that is not available for reference signal transmission. Broadly, the resource overlap may correspond to one or more symbols that are not available for reference signal transmission but are otherwise included in the configured reference signal transmission set. For example, the resource overlap may correspond to a symbol that is configured as a downlink symbol or a flexible symbol configured for downlink transmission, or is assigned to another uplink channel with a higher priority than the reference signal transmission, or is assigned as a guard symbol, or is assigned for a measurement gap / RF retuning gap, and / or is otherwise configured as not available for reference signal transmission by implicit and / or explicit signaling. In some aspects, the resource overlap may be identified after the base station configures the UE with a reference signal transmission set, e.g., between the triggering DCI and the start time slot indicated in the time slot offset.

[0137] At 315, the base station and / or the UE may identify one or more transmission attributes of the reference signal transmission set. Examples of transmission attributes include, but are not limited to, any combination of the following: the length of the SRS resource, the ratio of the number of conflicting symbols to the length of the SRS resource, the use / purpose of the SRS resource, the position of the conflicting SRS symbols relative to the SRS burst, whether the SRS is configured with interleaving and / or repetition, etc.

[0138] Thus, at 320, the UE may determine whether to omit one or more reference signal transmissions from the reference signal transmission set in the corresponding resource overlap or delay the transmission of the reference signal transmission set. Since the base station knows the transmission attributes configured for the UE, these techniques may be followed to determine whether the UE omits one or more reference signal transmissions in the corresponding resource overlap or delays the transmission of the reference signal transmission set. For example, the base station may send a configuration signal to the UE that configures or otherwise identifies which transmission attributes to consider and any associated thresholds / weighting factors to apply to the corresponding transmission attributes. The base station may configure the UE with the relevant transmission attributes and their associated thresholds / weighting factors once (e.g., for any configured reference signal transmission set), periodically (e.g., for the configured reference information transmission sets occurring within the period), as needed (e.g., the UE may be reconfigured with different transmission attributes based on various triggering conditions), and / or based on each SRS burst configuration (e.g., which transmission attributes are relevant for any configured and / or active reference signal transmission set may be signaled).

[0139] Accordingly, at 325, the UE may determine to omit some reference signal transmissions, but transmit other reference signal transmissions within the set of reference signal transmissions. That is, the UE may determine to omit reference signal transmissions from the set of reference signal transmissions in the corresponding resource overlap (e.g., omit SRS transmissions in conflicting symbols). The UE may transmit other reference signal transmissions from the set of reference signal transmissions in symbols different from the resource overlap (e.g., transmit SRS transmissions in non-conflicting symbols).

[0140] Conversely, at 330, the UE may determine to delay the transmissions of the set of reference signal transmissions to a subsequent time slot. For example, the UE may determine that the set of reference signal transmissions configured by the base station for time slot N may be delayed by Δ time slots.

[0141] Since the base station has configured the UE with relevant transmission attributes and their corresponding thresholds / weighting factors, it may know which reference signals the UE is omitting, delaying, or transmitting.

[0142] Figure 4 An example of a process 400 that supports reference signal transmission omission and postponement in accordance with aspects of the present disclosure is shown. In some examples, process 400 may implement aspects of the wireless communication system 100 and / or 200 and / or method 300. Aspects of process 400 may be implemented by the UE 405 and / or the base station 410 (which may be examples of the corresponding devices described herein).

[0143] At 415, the base station 410 may transmit (and the UE 405 may receive) a configuration signal (e.g., an RRC signal) that configures the UE 404 with a set of reference signal transmissions. The set of reference signal transmissions may correspond to an SRS resource set with a repetition factor R, where R represents the number of reference signal transmissions within consecutive symbols of a time slot. That is, the set of reference signal transmissions may correspond to an SRS resource set configured for an SRS burst within a time slot.

[0144] At 420, the UE 405 may identify a resource overlap between the set of reference signal transmissions and another resource that is not available for reference signal transmission. That is, the UE 405 may determine or otherwise identify one or more symbols that are not available for reference signal transmission but are otherwise configured within the set of reference signal transmissions. This may indicate that the symbol or resource is thus not available for reference signal transmission by the UE 405.

[0145] Similarly, at 425, the base station 410 may identify a resource overlap between a set of reference signal transmissions and another resource that is not available for reference signal transmission. That is, the base station 410 may determine or otherwise identify one or more symbols that are not available for reference signal transmission but are otherwise configured within the set of reference signal transmissions. This may indicate that the symbols or resources are thus not available for reference signal transmission by the UE 405. For example, the base station 410 may have configured the UE 405 with a set of reference signal transmissions multiple time slots in advance (e.g., with a high time slot offset number, such as 8, 16, or even 32 time slots). Subsequently, one or more symbols within the set of reference signal transmissions may become unavailable for reference signal transmission due to any number of factors, such as a time slot format change, scheduling higher priority communication for the corresponding symbol, and so on.

[0146] At 430, the UE 405 may identify one or more transmission attributes of the set of reference signal transmissions. The UE 405 may autonomously identify and select the transmission attributes to apply to the set of reference signal transmissions, and / or may be configured with the transmission attributes to apply to the set of reference signal transmissions. For example, the base station 410 may send a signal to the UE 405 that identifies or otherwise configures the transmission attributes to consider, as well as any associated thresholds, weighting factors, and so on.

[0147] Similarly, at 435, the base station 410 may identify one or more transmission attributes of the set of reference signal transmissions. In an example where the base station 410 configures the UE 405 with the associated transmission attributes, the base station 410 may identify the transmission attributes to apply to the set of reference signal transmissions based on the configuration. In cases where the UE 405 autonomously identifies the transmission attributes of the set of reference signal transmissions, the base station 410 may otherwise know the same factors that the UE 405 is considering in order to obtain or otherwise identify the same transmission attributes, e.g., using common configuration information known to each device.

[0148] At 440, the UE 405 will determine whether to omit one or more reference signal transmissions from the set of reference signal transmissions in the corresponding resource overlap or delay the transmission of the set of reference signal transmissions based on the transmission attributes and the resource overlap. Similarly, at 445, the base station 410 will determine whether the UE 405 will omit one or more reference signal transmissions from the set of reference signal transmissions in the corresponding resource overlap or delay the transmission of the set of reference signal transmissions based on the transmission attributes and the resource overlap.

[0149] For example, UE 405 and / or base station 410 may identify the nature of the resource overlap (e.g., the number and / or location of conflicting symbols that are not available for reference signal transmission). UE 405 and / or base station 410 may identify transmission attributes such as, but not limited to: the length of the reference signal transmission set, the ratio of resource overlap of the reference signal transmission set, the use / purpose of the reference signal transmission set, the location of resource overlap within the reference signal transmission set, whether the reference signal transmission set is configured for interleaving and / or repetition, etc. Based on the nature of the resource overlap and the transmission attributes being considered (and associated threshold levels, weighting factors, etc.), UE 405 may make an omission / delay determination for the reference signal transmission set. Since base station 410 knows the nature of the resource overlap and the transmission attributes being considered by UE 405 (and associated threshold levels, weighting factors, etc.), base station 410 may make the same determination as UE 405 and thus know which reference signals are being transmitted and which reference signals are being delayed.

[0150] At 450, UE 405 may transmit (and base station 410 may receive) at least a portion of the reference signal transmission set based on the omission / delay determination. For example, if UE 405 determines to omit reference signal transmission in the corresponding resource overlap, UE 405 may transmit some of the reference signal transmissions from the reference signal transmission set. Otherwise, if UE 405 determines to delay the transmission of the reference signal transmission set, UE 405 may transmit all of the reference signal transmissions from the reference signal transmission set in a later time slot.

[0151] Figure 5 FIG. 500 is a block diagram of a device 505 that supports reference signal transmission omission and deferral in accordance with aspects of the present disclosure. Device 505 may be an example of aspects of UE 115 as described herein. Device 505 may include a receiver 510, a communication manager 515, and a transmitter 520. Device 505 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).

[0152] The receiver 510 may receive information such as packets, user data, or control information associated with various information channels (e.g., control channels, data channels, and information related to reference signal transmission omission and deferral, etc.). The information may be passed to other components of device 505. The receiver 510 may be an example of aspects of the transceiver 820 described in Figure 8 The receiver 510 may utilize a single antenna or a set of antennas.

[0153] The communication manager 515 may perform the following operations: receive a configuration signal that configures a set of reference signal transmissions; identify a resource overlap between the set of reference signal transmissions and another resource that is not available for reference signal transmission; identify one or more transmission attributes of the set of reference information transmissions; determine whether to omit one or more of the reference signal transmissions in the set of reference signal transmissions in the corresponding resource overlap or delay the transmission of the set of reference information transmissions based on the one or more transmission attributes and the resource overlap; and transmit at least a portion of the set of reference signal transmissions based on the determination. The communication manager 515 may be an example of aspects of the communication manager 810 described herein.

[0154] The communication manager 515 or its sub-components may be implemented in hardware, code executed by a processor (e.g., software or firmware), or any combination thereof. If implemented in code executed by a processor, the functions of the communication manager 515 or its sub-components may be performed by a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described in this disclosure.

[0155] The communication manager 515 or its sub-components may be physically located in various locations, including being distributed such that portions of the functions are implemented by one or more physical components in different physical locations.
