Description

Technical Field

[0001] The following relates generally to wireless communications and, more particularly, to updating bandwidth portion widths from a default configuration.

[0002] background

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced 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 various technologies, such as 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 multiple 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 with multiple communication devices, which may be referred to as user equipment (UE) in addition.

[0004] Devices operating in a wireless communication environment may be associated with resource thresholds or limitations that may degrade device performance and increase system interference.

[0045] Detailed Description

[0046] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems can support multiple devices and communication directions. Devices operating in wireless communication systems may operate or be associated with default bandwidth parts (BWP) and power spectrum density (PSD) thresholds or limits. In some cases, devices and / or communication directions may be associated with default BWP and PSD limits. The default BWP may have a default BWP width, and the PSD may be associated with a per-megahertz (MHz) transmit power limit. For example, a base station may operate at a first PSD threshold (e.g., 5 decibel milliwatts (dBm) per MHz), while a user equipment (UE) may operate at a second PSD threshold (e.g., -1 dBm / MHz). In some additional or alternative examples, a base station may operate within a first default BWP (e.g., 20 MHz), while a UE may operate within a second default BWP (e.g., 20 MHz). In some cases, the PSD limit, the width of the BWP, or a combination thereof may be associated with a reduction in transmit power and / or an increase in transmission interference. UEs operating in the 6 GHz spectrum band may operate according to a PSD threshold and be configured with a default initial BWP (e.g., a default initial uplink BWP, a default initial downlink BWP, etc.) In some cases, a narrow default initial BWP (e.g., 20 GHz) paired with a PSD threshold (e.g., -1 dBm / MHz) may result in lower overall transmit power and greater interference susceptibility.

[0047] According to various aspects described herein, the UE may communicate with the base station based on the second BWP to increase transmit power and / or reduce transmission interference. The second BWP may be wider than the first BWP (e.g., default BWP, initial BWP, etc.), which may increase transmit power and / or reduce transmission interference. In some examples, the second BWP may be based on the first BWP, a scaling factor, or a combination thereof. In some additional or replacement examples, the center frequency of the first BWP may be aligned with the center frequency of the second BWP. For example, the first BWP may correspond to a default downlink BWP, the second BWP may correspond to an initial uplink BWP, and the width of the second BWP may correspond to an odd multiple of the width of the first BWP. As an additional or replacement example, the first BWP may correspond to an initial downlink BWP, the second BWP may correspond to an initial uplink BWP, and the width of the initial downlink BWP and the width of the initial uplink BWP may be based on the scaling of the default BWP.

[0048] The UE may receive an indication of a second BWP from a base station. The indication may be received in a system information block (SIB), a remaining minimum system information (RMSI), a physical downlink shared channel (PDSCH), a master information block (MIB), a synchronization signal block (SSB), etc. The UE may select a second BWP based on the received indication and / or the operating frequency band of the base station. In some examples, the UE and the base station may communicate based on the second BWP. For example, the base station may transmit PDSCH data based on the second BWP, and the UE may receive PDSCH data based on the second BWP. In some additional or alternative examples, the base station may transmit a control resource set (CORESET), a physical downlink control channel (PDCCH), downlink control information (DCI), or any combination thereof based on the second BWP. In some examples, a resource band (e.g., a 6 GHz resource band) may be associated with a power limit (e.g., a PSD limit), and operating or communicating based on a second BWP (e.g., a wide BWP) may improve transmit power and reduce transmission interference.

[0049] Various aspects of the present disclosure are initially described in the context of a wireless communication system. Various aspects are subsequently described with respect to additional wireless communication systems, several bandwidth portion configuration systems, and process flows. Various aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams associated with updating bandwidth portion widths from a default configuration.

[0050] Figure 1 An example of a wireless communication system 100 that supports updating bandwidth portion widths from a default configuration in accordance with various aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-A Pro network, or a new radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low latency communications, communications with low-cost and low-complexity devices, or any combination thereof.

[0051] The base stations 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may be different forms of devices or devices with different capabilities. The base stations 105 and the UEs 115 may communicate wirelessly via one or more communication links 125. Each base station 105 may provide a coverage area 110 over which the UEs 115 and the base stations 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area over which the base stations 105 and the UEs 115 may support communication of signals according to one or more radio access technologies.

[0052] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be different forms of devices or devices with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, base stations 105, or network equipment (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network equipment), such as Figure 1 as shown in .

[0053] Each base station 105 may communicate with the core network 130, or communicate with each other, or both. For example, the base station 105 may 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 may communicate with each other directly (e.g., directly between the base stations 105), or indirectly (e.g., via the core network 130), or directly and indirectly on the backhaul link 120 (e.g., via X2, Xn or other interfaces). In some examples, the backhaul link 120 may be or include one or more wireless links.

[0054] One or more of the base stations 105 described herein may include or may be referred to by a person of ordinary skill in the art as a base transceiver station, a radio base station, an access point, a radio transceiver, a B node, an evolved B node (eNB), a next generation B node or a gigabit B node (any of which may be referred to as a gNB), a home B node, a home evolved B node, or other suitable terminology.

[0055] 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 a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. 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, 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, etc., which may be implemented in various objects such as electrical appliances or vehicles, meters, etc.

[0056] The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as base stations 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, etc. Figure 1 as shown in .

[0057] The UE 115 and the base station 105 may communicate wirelessly with each other via one or more communication links 125 on one or more carriers. The term "carrier" may refer to a set 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 portion (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 carrier operations, user data, or other signaling. The wireless communication system 100 may support communication with the UE 115 using carrier aggregation or multi-carrier operation. The UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used in conjunction with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.

[0058] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling that coordinates the operation of 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 located according to a channel grid for discovery by UE 115. A carrier may operate in a standalone mode in which initial acquisition and connection may be made by UE 115 via the carrier, or a carrier may operate in a non-standalone mode in which a connection is anchored using a different carrier (e.g., a different carrier of the same or different radio access technology).

[0059] The communication link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. A carrier may carry downlink or uplink communications (e.g., in an FDD mode), or may be configured to carry both downlink and uplink communications (e.g., in a TDD mode).

[0060] A carrier may be associated with a particular bandwidth of a radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as a "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several determined bandwidths (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)) of a carrier of a particular radio access technology. A device (e.g., a base station 105, a UE 115, or both) of the wireless communication system 100 may have a hardware configuration that supports communications on a particular carrier bandwidth, or may be configurable to support communications on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or a UE 115 that supports simultaneous communications 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 subband, a BWP) or all of a carrier bandwidth.

[0061] The signal waveform transmitted on the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system using MCM technology, a resource element may include a code element period (e.g., the duration of a modulation code element) and a subcarrier, where the code element period and the subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the code rate of the modulation scheme, or both). Thus, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 can be. Wireless communication resources may 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 improve the data rate or data integrity of communication with UE 115.

[0062] One or more parameter designs for a carrier may be supported, where the parameter designs may include subcarrier spacing (Δf) and cyclic prefixes. A carrier may be divided into one or more BWPs with the same or different parameter designs. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications for a UE 115 may be limited to the one or more active BWPs.

[0063] The time interval of the base station 105 or the UE 115 can be expressed as a multiple of a basic time unit, and the basic time unit can be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, where Δf max It can represent the maximum supported subcarrier spacing, and Nf The maximum supported discrete Fourier transform (DFT) size may be indicated. Time intervals of communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0064] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe 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 subcarrier spacing. Each time slot may include a number of code element periods (e.g., depending on the length of the cyclic prefix added before each code element period). In some wireless communication systems 100, a time slot may be further divided into a plurality of mini-time slots containing one or more code elements. Excluding the cyclic prefix, each code element period may contain one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating band.

[0065] A subframe, slot, mini-slot, or symbol 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 bursts of shortened TTIs (sTTIs)).

[0066] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier, for example, using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) for a physical control channel may be defined by a number of symbol periods and may extend across a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set 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 in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0067] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with a base station 105 (e.g., on a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other) used to distinguish adjacent cells. In some examples, a cell may also refer to a geographic coverage area 110 or a portion of a geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. The range of such a cell may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area depending on various factors (such as the capabilities of the base station 105). For example, a cell may be or include a building, a subset of a building, or an external space between or overlapping a geographic coverage area 110, as well as other examples.

[0068] A macro cell generally covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access to UEs 115 that have service subscriptions with a network provider that supports the macro cell. A small cell may be associated with a lower power base station 105 (compared to a macro cell), and the small cell may operate in the same or different (e.g., licensed, unlicensed) frequency band as the macro cell. A small cell may provide unrestricted access to UEs 115 that have service subscriptions with a network provider, or may provide restricted access to UEs 115 associated with the small cell (e.g., UEs 115 in a closed subscriber group (CSG), UEs 115 associated with users in a home or office). A base station 105 may support one or more cells and may also support communications on one or more cells using one or more component carriers.

[0069] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0070] In some examples, base stations 105 may be mobile and thus provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but the different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of base stations 105 provide coverage for various geographic coverage areas 110 using the same or different radio access technologies.

[0071] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the base stations 105 may have similar frame timing, and transmissions from different base stations 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timing, and transmissions from different base stations 105 may not be aligned in time in some examples. The techniques described herein may be used for synchronous or asynchronous operation.

[0072] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate 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 person interacting with the application. Some UEs 115 may 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, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0073] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed with a reduced peak rate. Other power saving techniques for UE 115 include entering a power saving deep sleep mode when not engaged in active communications, operating on a limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a subcarrier or resource block (RB) set) within a carrier, within a guard band of a carrier, or outside a carrier.

[0074] 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. UE 115 may be designed to support ultra-reliable, 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, critical mission, and ultra-reliable low latency may be used interchangeably herein.

[0075] In some examples, UE 115 may also be able to communicate directly with other UE 115 over a device-to-device (D2D) communication link 135 (e.g., using a peer-to-peer (P2P) or D2D protocol). One or more UEs 115 utilizing D2D communication may be within a geographic coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographic coverage area 110 of the base station 105, or may not be able to receive transmissions from the base station 105 for other reasons. In some examples, each group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, wherein each UE 115 transmits to each other UE 115 in the group. In some examples, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between each UE 115 without involving the base station 105.

[0076] 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, the vehicles can communicate using vehicle-to-everything (V2X) communications, vehicle-to-vehicle (V2V) communications, or some combination of these communications. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in the V2X system can communicate with roadside infrastructure (such as roadside units), or with the network, or both via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communications.

[0077] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), and the EPC or 5GC may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by a base station 105 associated with the core network 130. User IP packets may be delivered via a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to a network operator IP service 150. The network operator IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0078] Some network devices (such as base stations 105) may include subcomponents, such as access network entities 140, which may be examples of access node controllers (ANCs). Each access network entity 140 may communicate with each UE 115 through one or more other access network transport entities 145, which may be referred to as radio heads, smart radio heads, or transmission / reception points (TRPs). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across various network devices (e.g., radio heads and ANCs) or merged into a single network device (e.g., base station 105).

[0079] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). In general, the 300 MHz to 3 GHz region is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from about 1 decimeter to 1 meter long. UHF waves may be blocked or redirected by buildings and environmental features, but these waves may penetrate various structures sufficiently for macro cells to provide service to UEs 115 located indoors. Transmissions using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than transmissions using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0080] The wireless communication system 100 may also operate in a super high frequency (SHF) zone using a frequency band from 3 GHz to 30 GHz (also known as a centimeter band) or in an extremely high frequency (EHF) zone of a spectrum (e.g., from 30 GHz to 300 GHz) (also known as a millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and base station 105, and the EHF antenna of the corresponding device may be smaller and more closely spaced than the UHF antenna. In some examples, this may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and a shorter range than SHF or UHF transmissions. The technology disclosed herein may be adopted across transmissions using one or more different frequency zones, and the use of frequency bands specified across these frequency zones may vary by country or regulatory agency.

[0081] 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 band (such as the 5 GHz industrial, scientific, and medical (ISM) band). When operating in an unlicensed radio frequency spectrum band, devices (such as base stations 105 and UEs 115) may employ carrier sensing for conflict detection and avoidance. In some examples, operations in an unlicensed band may be based on a carrier aggregation configuration (e.g., LAA) in coordination with component carriers operating in a licensed band. Operations in an unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.

[0082] The base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the base station 105 or UE 115 may be located in one or more antenna arrays or antenna panels that can support MIMO operations 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 antenna ports of several rows and columns that the base station 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support radio frequency beamforming for signals transmitted via the antenna ports.

[0083] The base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such technology may be referred to as spatial multiplexing. For example, the transmitting device may transmit multiple signals via different antennas or different antenna combinations. Similarly, the receiving device may receive multiple signals via different antennas or different antenna combinations. 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 technology includes single-user MIMO (SU-MIMO), in which multiple spatial layers are transmitted to the same receiving device; and multi-user MIMO (MU-MIMO), in which multiple spatial layers are transmitted to multiple devices.

[0084] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals communicated via antenna elements of an antenna array so that some signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each antenna element may 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).

[0085] The base station 105 or the UE 115 may use beam sweeping techniques as part of a beamforming operation. For example, the base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with the UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be transmitted multiple times by the base station 105 in different directions. For example, the base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device (such as the base station 105) or a receiving device (such as the UE 115)) to identify a beam direction used by the base station 105 for later transmission or reception.

[0086] Some signals, such as data signals associated with a particular recipient device, may be transmitted by base station 105 in a single beam direction, e.g., a direction associated with a recipient device, such as UE 115. In some examples, a beam direction associated with transmissions along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0087] In some examples, transmission by a device (e.g., by a base station 105 or a UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or radio frequency beamforming to generate a combined beam for transmission (e.g., from the base station 105 to the UE 115). The 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. The base station 105 may transmit a reference signal that may be precoded or unprecoded (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)). The UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel type codebook, a linear combination type codebook, a 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 use similar techniques to transmit signals multiple times in different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0088] A receiving device (e.g., UE 115) may try multiple reception configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a base station 105. For example, the receiving device may try multiple reception directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different reception configurations or reception directions. In some examples, the receiving device may use a single reception configuration to receive along a single beam direction (e.g., when receiving a data signal). The single reception configuration may be aligned on a beam direction determined based on listening according to different reception configuration directions (e.g., a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0089] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication of the bearer or packet data convergence protocol (PDCP) layer may be IP-based. The radio link control (RLC) layer may perform packet segmentation and reassembly to communicate on a logical channel. The media access control (MAC) layer may perform priority handling and multiplex logical channels into transport channels. The MAC layer may also use error detection techniques, error correction techniques, or both to support retransmission of the MAC layer to improve link efficiency. In the control plane, the radio resource control (RRC) protocol layer may provide the establishment, configuration, and maintenance of an RRC connection that supports radio bearers of user plane data between UE 115 and base station 105 or core network 130. In the physical layer, transport channels may be mapped to physical channels.

[0090] UE 115 and base station 105 may 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 on communication link 125. HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ may improve the throughput of the MAC layer in poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support simultaneous slot HARQ feedback, wherein the device may provide HARQ feedback in a specific time slot for data received in a previous symbol in the time slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0091] According to some aspects, UE 115 may support updating the BWP width from a default configuration. UE 115 may identify a first BWP, where the first BWP is a default BWP for communication with base station 105. UE 115 may receive an indication of a second BWP wider than the first BWP from base station 105, and select the second BWP for communication with base station 105 based on the received indication and the operating frequency band of base station 105. In some cases, base station 105 may transmit the indication in RMSI or MIB. Communicating based on the second BWP (e.g., an updated BWP) may increase transmit power and reduce transmission interference.

[0092] Figure 2An example of a wireless communication system 200 that supports updating bandwidth portion widths from a default configuration in accordance with aspects of the present disclosure is illustrated. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. The wireless communication system 200 can include a base station 105-a and a UE 115-a. In general, the wireless communication system 200 illustrates an example in which the base station 105-a can transmit BWP configuration information 205 to the UE 115-a.

[0093] In some cases, a wireless communication system may operate in a frequency band with relatively strict PSD requirements. In this case, operation in a relatively narrow default BWP may be associated with a lower transmit power than the transmit power for the same bandwidth portion in a frequency band with less stringent PSD requirements. This lower transmit power may in turn reduce the signal quality between the base station 105-a and the UE 115-a, making the link between the base station 105-a and the UE 115-a more susceptible to interference. The default BWP may be specified by a technical standard or a regulatory body, and the device may be configured to operate based on the default BWP. In some cases, increasing the width of the BWP may increase the transmit power while maintaining compliance with the PSD constraints, thereby improving the link quality between the UE 115-a and the base station 105-a.

[0094] In one example, UE 115-a may communicate with base station 105-a, and UE 115-a and / or base station 105-a may operate in a 6 GHz band, and the band may be associated with several PSD limits or thresholds. In some cases, one or more PSD limits may be lower than PSD limits associated with other spectrum bands (e.g., 5 GHz spectrum bands). A device (e.g., user equipment 115-a, base station 105-a) may be associated with a default BWP (e.g., 20 MHz), and the transmit power of the device may be limited by the width of the default BWP. Techniques for increasing the BWP width are described herein, thereby improving transmit power and reducing interference.

[0095] In some cases, the UE 115-a may identify a first BWP, and the first BWP may be a default BWP for communication with the base station 105-a. The default BWP may be based on a spectrum band, a technical document, a technical standard, etc. The UE 115-a may receive an indication of a second BWP wider than the first BWP from the base station 105-a (e.g., BWP configuration information 205), and select the second BWP based on the received indication. The indication may include a first transmission 210 (e.g., RMSI, SIB1, PDSCH, etc.) and / or a second transmission 215 (e.g., MIB, SSB, etc.). The RMSI may be received by the UE 115-a on the PDSCH, and the RMSI may include additional system information that is not included in the MIB or SIB. In some examples, the received indication may include a scaling factor, and / or one or more of the number of resource blocks (RBs), the number of symbols, or an RB offset. For example, the first transmission 210 may indicate one or more scaling factors, and the UE 115-a may select the bandwidth of the second BWP based on the one or more scaling factors, the width of the first BWP, or a combination thereof. In some additional or alternative scenarios, the second transmission 215 may indicate one or more configurations of RBs, symbols, or RB offsets, and the UE 115-a may select the width of the second BWP based on the one or more configurations. The UE 115-a may select a second BWP having a center frequency aligned with the center frequency of the first BWP. Selecting a second BWP having a center frequency aligned with the center frequency of the first BWP may reduce errors and increase system compatibility.

[0096] Figure 3A , 3B 3C illustrate examples of bandwidth portion configuration techniques that support updating bandwidth portion widths from a default configuration according to aspects of the present disclosure. In some examples, bandwidth portion configuration systems 301, 302, or 303 may implement aspects of wireless communication system 100. In some cases, a UE may be configured to have a default downlink BWP and / or a default uplink BWP width (e.g., 20 MHz), and the UE may communicate with a base station using the default BWP unless one or both of the BWPs are reconfigured by system information received from the base station. For example, UE 115 may receive transmission 315 and transmission 320 from base station 105, and UE 115 may select an initial uplink BWP 325 and / or an initial downlink BWP 330 based on the received transmissions.

[0097] Figure 3AAn example of a bandwidth portion configuration technique 301 that supports configuring an initial uplink BWP 325-a to be different from a default initial uplink BWP is illustrated. The width of the initial uplink BWP 325-a can be greater than the bandwidth of the default initial downlink BWP 305-a. In some examples, the width of the initial uplink BWP 325-a (e.g., the combined width of 310-a, 310-b, 310-c, 300-d, and 310-e) can be an odd multiple of the width of the default initial downlink BWP 305-a, and the center frequency of the default initial downlink BWP 305-a can be aligned with the center frequency of the initial uplink BWP 325-a, which can reduce or prevent system errors.

[0098] In some cases, the UE may receive a transmission 320-a that includes an SSB including a MIB and / or a SIB. The UE may identify CORESET 0 based on the MIB, and the UE may receive a transmission 320-b that includes a PDCCH DCI. The DCI may include a downlink grant for the UE, and the UE may receive a transmission 315-a that includes an RMSI based on the downlink grant. For example, the UE may receive the transmission 315-a on the PDSCH using the resources indicated in the DCI, and the transmission 315-a may include an RMSI that signals a change from a default initial uplink BWP to an initial uplink BWP 325-a. In some examples, the width of the initial uplink BWP 325-a may be based on the RMSI in the transmission 315-a, and the initial uplink BWP 325-a may be wider than the default initial downlink BWP 305-a. In some additional or alternative examples, the width of the initial uplink BWP 325-a can be signaled as a scaling factor (e.g., M), where the reconfigured width of the initial uplink BWP 325-a is determined by the formula (2M+1) x default downlink BWP size. Signaling the scaling factor is feasible when the default initial downlink BWP 305-a and the initial uplink BWP 325-a share a center frequency, and when the reconfigured width of the initial uplink BWP 325-a is an odd multiple of the default initial downlink BWP 305-a. For example, if the default initial downlink 305-a has a width of 20 MHz, the initial uplink BWP 325-a can be reconfigured to 60 MHz by signaling the scaling factor M=3 in the RMSI of the transmission 325-a.

[0099] Figure 3BAn example of a bandwidth portion configuration technique 302 that supports configuring an initial uplink BWP 325-b to be different from a default initial uplink BWP and configuring an initial downlink BWP 330-a to be different from a default initial downlink BWP is illustrated. The width of the initial downlink BWP 330-a may be greater than the width of the default initial downlink BWP, and the width of the initial uplink BWP 325-b may be greater than the width of the default initial uplink BWP. In some examples, the width of the initial downlink BWP 330-a (e.g., the combined width of 305-b, 305-c, 305-d, 305-e, and 305-f) and the width of the initial uplink BWP 325-b (e.g., the combined width of 310-f, 310-g, 310-h, 310-i, and 310-j) can be multiples of the width of the default initial BWP, and the center frequency of the initial downlink BWP 330-a can be aligned with the center frequency of the initial uplink BWP325-b.

[0100] In some cases, the UE may receive a transmission 320-c that includes an SSB including a MIB and / or a SIB. The UE may identify CORESET 0 based on the MIB, and the UE may receive a transmission 320-d that includes a PDCCH DCI. The DCI may include a downlink grant for the UE, and the UE may receive a transmission 315-b that includes an RMSI based on the downlink grant. For example, the UE may receive a transmission 315-b on the PDSCH using the resources indicated in the DCI, and the transmission 315-b may include an RMSI that signals a change from a default initial uplink BWP to an initial uplink BWP 325-b and / or a change from a default initial downlink BWP to an initial downlink BWP 330-a. In some examples, the width of the initial uplink BWP 325-b and the width of the initial downlink BWP 330-a may be based on the RMSI in the transmission 315-b, and the initial uplink BWP 325-b may be wider than the default initial uplink BWP, while the initial downlink BWP 330-a may be wider than the default initial downlink BWP. In some additional or alternative examples, the width of the initial uplink BWP 325-b may be signaled as a scaling factor (e.g., M), where the reconfiguration width of the initial uplink BWP 325-b is determined by the formula (M) x the default initial uplink BWP size. The width of the initial downlink BWP 330-a may be signaled as a scaling factor (e.g., N), where the reconfiguration width of the initial downlink BWP 330-a is determined by the formula (N) x the default initial downlink BWP size. In some cases, the scaling factors M and N may be the same, while in other cases, they may be different.

[0101] Figure 3C An example of a bandwidth portion configuration technique 303 is illustrated that supports configuring an initial downlink BWP 330-b by indicating a wider CORESET 0 in a MIB (eg, a MIB included in transmission 315-c). Figure 3C Additionally supported is configuration of the initial uplink BWP 325-c based on the RMSI included in the transmission 315-d.

[0102] In some cases, the UE may receive a transmission 315-c that includes an SSB including a MIB and / or a SIB. In some cases, the MIB may indicate a bandwidth of CORESET 0 that is wider than a default downlink initial BWP, and the UE may identify CORESET 0 based on the bandwidth and / or the MIB. The UE may additionally receive a transmission 320-e that includes a PDCCH DCI based on the bandwidth. In some cases, the width of the initial downlink BWP 330-b (e.g., the combined width of 305-g, 305-h, 305-i, 305-j, 305-k) may be the same as the width of the bandwidth of CORESET 0. In some additional or alternative cases, the RMSI included in the transmission 315-d may include an indication of the bandwidth of the initial uplink BWP 325-c. The width of the initial uplink BWP 325-c (e.g., the combined width of 310-k, 310-l, 310-m, 310-n, and 310-o) can be based on the RMSI of the transmission 315-d. The width of the initial downlink BWP 330-b can remain as indicated in the MIB, or the width of the initial downlink BWP 330-b can be changed by the RMSI.

[0103] In some examples, the MIB may include 8 reserved entries that may reconfigure the CORESET 0 bandwidth by indicating a combination of the number of RBs, the number of symbols, or an offset (e.g., an RB offset). In some cases, the MIB may include several entries (e.g., 8 entries) or configurations. Some configurations may include limiting the subband offset from SSB to CORESET 0 (e.g., SSB is the lowest subband in CORESET 0), limiting the RB offset (e.g., limiting the RB offset supported from a single subband CORESET 0), limiting the number of symbols in a CORESET (e.g., 2 symbols for improved coverage), etc.

[0104] Table 1 illustrates an example of a subcarrier spacing (SCS) of 30 kHz. The 8 reserved entries (e.g., rows at indices 8-15) may show configurations of 2x20 MHz bandwidth and 4x20 MHz bandwidth with 1 or 2 OFDM symbols and an offset subset (e.g., 1 and 3) of a 30 kHz SCS. Table 1 may illustrate a set of RBs and slot symbols for a CORESET of a Type 0-PDCCH search space set when {SS / PBCH block, PDCCH} SCS is {30, 30} KHz.

[0105]

[0106] Table 1
