Background Art

[0002]

[0002] The following generally relates to wireless communication, and more particularly, to frequency division multiplexing (FDM) for bandwidth part (BWP) transmission with mixed attributes.

[0003]

[0003] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. 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 multi-connection systems include fourth-generation (4G) systems such as the Long-Term Evolution (LTE (R)) system or the Long-Term Evolution Advanced (LTE-A) system, and fifth-generation (5G) systems that may be referred to as New Radio (NR) systems. These systems may employ techniques 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 Multiple Access (DFT-s-OFDM). A wireless multi-connection communication system may include several base stations or network access nodes, each supporting communication simultaneously for a plurality of communication devices that may be known as user equipment (UE) by another name.

[0004]

[0004] In some wireless communication systems (e.g., systems that support millimeter wave (mmW) communication), beamforming can be used to overcome the relatively high path loss associated with the frequencies in these systems. To support beamformed transmissions, communication wireless devices (e.g., base stations and UEs) can be operable to discover and maintain an appropriate beam for a given communication link via synchronization signals. The synchronization signals can be transmitted in synchronization signal (SS) blocks, which can also be used, for example, for cell acquisition procedures, cell timing synchronization, etc. Further, in such wireless communication systems, connections can be established using a relatively wide channel frequency bandwidth. In some cases, one or more portions of the channel frequency bandwidth, called bandwidth parts (BWPs), can be used for communication with a UE. In such cases, when a relatively small amount of data is transferred between the UE and the base station, a single BWP can be used for transmission, and when a relatively large amount of data is transferred, two or more BWPs can be used for transmission. In some examples, such connections can be made according to carrier aggregation (CA) mode, and multiple component carriers (CCs), each of which can have one or more BWPs, can be used together to provide high data rate communication. Transmission attributes used for transmission within a CC or BWP (e.g., subcarrier spacing (SCS), transmission beam direction, etc.) can be different from the transmission attributes used for the SS block. Complexity can arise, for example, due to the capabilities of the receiving UE to handle such mixed transmission attributes when both the transmission within the BWP and the SS block are to be communicated (e.g., via frequency division multiplexing (FDM)). Thus, efficient techniques for handling the mixed transmission attributes associated with the SS block and transmission within the BWP may be desirable.

Summary of the Invention

[0005]

[0005] The techniques described relate to an improved method, system, device, or apparatus that supports frequency division multiplexing (FDM) for bandwidth part (BWP) transmission with mixed attributes. Generally, the techniques described provide an efficient handling of synchronization signal (SS) blocks within a BWP and mixed transmission attributes associated with the transmission (e.g., subcarrier spacing (SCS), transmission and / or reception beam directions, etc.). A user equipment (UE) may maintain timing synchronization (e.g., symbol timing synchronization) with a cell by monitoring SS blocks routinely transmitted by a base station. In some cases, the base station may utilize FDM techniques to transmit SS blocks and downlink transmissions (e.g., physical downlink shared channel (PDSCH), physical downlink control channel (PDCCH), channel state information reference signal (CSI-RS), etc.).

[0006]

[0006] According to an aspect of the present disclosure, a base station may configure a configuration for a carrier's BWP for downlink transmission. The BWP configuration may include a first transmission attribute (e.g., BWP SCS, etc.) for downlink transmission within the BWP. The base station may then transmit a grant for downlink transmission to the UE. In some cases, the downlink transmission may be scheduled (e.g., via the grant) for a set of resources that temporally overlap with an SS block for the carrier. The downlink transmission may be associated with a transmission attribute such as a beam direction. When there is an overlap in time (e.g., at least a portion of the set of resources is FDM with the SS block), efficient techniques for handling the transmission attributes associated with the SS block and the transmission within the BWP are described herein.

[0007]

[0007] In the first example, the set of resources for downlink transmission that overlaps with the SS block can be transmitted using a second transmission attribute (e.g., SS block SCS, SS block beam direction, etc.). Further, the remainder of the downlink transmission (e.g., the remaining time resources of the downlink transmission that do not include the set of overlapping resources) can be transmitted using a first transmission attribute (e.g., a BWP SCS different from the SS block SCS, a beam direction different from the SS block beam direction, etc.). That is, the FDMed resources of the downlink transmission can be associated with the SS block transmission attribute in the time resources that overlap with the SS block, and the remaining time resources of the downlink transmission that are not FDM with the SS block can be associated with a different transmission attribute configured for the BWP (e.g., BWP transmission attribute) or the transmission (e.g., transmission that does not overlap with the SS block). For example, data transmission can be associated with a beam direction different from the SS block beam direction.

[0008]

[0008] In the second example, the entire downlink transmission can be transmitted using a transmission attribute configured for a BWP (e.g., a portion of the downlink transmission that is FDM with the SS block, or the time resources of the downlink transmission).

[0009]

[0009] In the third example, the entire downlink transmission can be transmitted using an SS block transmission attribute (e.g., a portion of the downlink transmission that is FDM with the SS block, or the time resources of the downlink transmission).

[0010]

[0010] In some cases, the implementation form of the techniques described above can be selected based on the FDM capabilities of the UE. For example, the base station can transmit downlink transmissions (using BWP transmission attributes and / or SS block transmission attributes) based on the capability message received from the UE. The capability message can indicate whether the UE supports FDM, supports FDM with hybrid transmission attributes, supports FDM reception on different beam directions, etc. Further, the FDM of the downlink transmissions within the configured BWP and SS block can refer only to the overlap with the SS block targeted at the UE. That is, the base station can transmit some SS blocks that may occur simultaneously with the downlink transmission to other UEs in the wireless communication system, but only the SS block targeted at the UE receiving the downlink transmission (e.g., the UE is expected to receive or monitor) is included when referring to FDM.

[0063] The base station may configure one or more synchronization signal (SS) blocks for transmission to a user equipment (UE) for cell acquisition and timing synchronization procedures. For example, the SS block may include symbols allocated for a primary SS (PSS), a secondary SS (SSS), and a physical broadcast channel (PBCH). Such SS blocks may be transmitted according to several SS block transmission attributes, such as some pre-defined numerologies (e.g., sub-carrier spacing (SCS)). For example, the SS block may be transmitted according to an SCS of 15 kHz or 30 kHz for an operating frequency below 6 GHz, and according to an SCS of 120 kHz or 240 kHz for an operating frequency above 6 GHz. Additionally, the base station may utilize one or more portions of the channel frequency bandwidth, called bandwidth parts (BWPs), for other downlink communications with the UE (e.g., physical downlink shared channel (PDSCH), physical downlink control channel (PDCCH), channel state information reference signal (CSI-RS), etc.). In some cases, such downlink transmissions within these configured BWPs may be associated with different transmission attributes (e.g., the SCS of the downlink transmission within the BWP may be different from the SS block SCS). For example, the SS block may never use a certain SCS (such as 60 kHz), and thus, the downlink transmission in the BWP associated with such an SCS will always have an SCS different from the SS block SCS.

[0055]

[0064] In some cases, the base station may use frequency division multiplexing (FDM) techniques to carry downlink transmissions and SS blocks. The base station may choose to transmit downlink transmissions within a BWP using transmission attributes configured for the BWP and / or using SS block transmission attributes, depending on various factors. Such factors may include the UE's capabilities, whether the resources of the downlink transmission at that instant are frequency division multiplexed with the SS block (e.g., whether the time resources of a particular downlink transmission overlap with the time resources of the SS block), etc. The techniques described herein provide efficient FDM handling or management of SS blocks along with other downlink transmissions.

Next, exemplary FDM scenarios that employ techniques for hybrid transmission attributes for transmission within a BWP are described. Aspects of the present disclosure are further illustrated by, and described with reference to, apparatus diagrams, system diagrams, and flowcharts related to FDM for BWP transmissions with hybrid attributes.

[0057]

[0066] FIG. 1 illustrates an example of a wireless communication system that supports FDM for BWP transmission with hybrid attributes according to an aspect of the present disclosure. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, the wireless communication system 100 can be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, or a New Radio (NR) network. In some cases, the wireless communication system 100 can support extended broadband communication, high-reliability (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices. The UE 115 can execute a cell acquisition procedure and a synchronization procedure with the base station 105 by monitoring SS blocks. When a connection is established, one or more BWPs can be configured for the communication link 125 between the base station 105 and the UE 115. In some cases, the base station 105 can utilize FDM for SS blocks (e.g., for synchronization) and downlink transmission within one or more configured BWPs.

[0058]

[0067] The base station 105 can communicate wirelessly with the UE 115 via one or more base station antennas. Each base station 105 can provide communication coverage for its respective geographic coverage area 110. The communication link 125 shown in the wireless communication system 100 can 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. Control information and data can be multiplexed on the uplink channel or the downlink channel according to various techniques. Control information and data can be multiplexed on the downlink channel using, for example, time-division multiplexing (TDM) techniques, FDM techniques, or hybrid TDM-FDM techniques. In some examples, the control information transmitted during the transmission time interval (TTI) of the downlink channel can be distributed (e.g., between a common control region and one or more UE-specific control regions) between different control regions in a cascaded manner.

[0059]

[0068] UE 115 can be distributed throughout the wireless communication system 100, and each UE 115 can be fixed or mobile. The mobile device 115 can also be referred to as a mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or some other suitable term of art. UE 115 can also be a cellular phone, a personal digital assistant (PDA), a wireless modem,, a wireless communication device, a handheld device, a tablet computer, a laptop computer, a cordless phone, a personal electronic device, a handheld device, a personal computer, a wireless local loop (WLL) station, an Internet of Things (IoT) device, all Internet of Everything (IoE) devices, a machine type communication (MTC) device, an electrical appliance, an automobile, or the like.

[0060]

[0069] In some cases, UE 115 can also be capable of communicating directly with other UEs (e.g., using a peer-to-peer (P2P) or device-to-device (D2D) protocol). One or more of the groups of UEs 115 utilizing D2D communication can be within the cell coverage area 110. Other UEs 115 in such a group can be outside the cell coverage area 110 or, for some other reason, unable to receive transmissions from the base station 105. In some cases, multiple groups of UEs 115 communicating via D2D communication can utilize a one-to-many (1:M) system in which each UE 115 transmits to every other UE 115 in the group. In some cases, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed independently of the base station 105.

[0061]

[0070] Some UEs 115, such as MTC or IoT devices, can be low-cost or low-complexity devices and can provide automated communication between machines, i.e., machine-to-machine (M2M) communication. M2M or MTC can refer to a data communication technology that enables devices to communicate with each other or with a base station without human intervention. For example, M2M or MTC can refer to communication from a device that integrates sensors or meters for measuring or capturing information and relays that information to an application program or a central server that can use that information or present that information to a human interacting with a program or application. Some UEs 115 can be designed to collect information or enable automated behavior of machines. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business charging.

[0062]

[0071] The base station 105 can communicate with the core network 130 and with each other. For example, the base station 105 can interface with the core network 130 through a backhaul link 132 (e.g., S1, etc.). The base station 105 can communicate with each other either directly or indirectly (e.g., through the core network 130) via a backhaul link 134 (e.g., X2, etc.). The base station 105 can perform radio configuration and scheduling for communication with the UE 115 or can operate under the control of a base station controller (not shown). In various examples, the base station 105 can be a macro cell, a small cell, a hot spot, etc. The base station 105 can also be referred to as an eNodeB (eNB) 105, a next-generation NodeB (gNB) 105, etc.

[0063]

[0072] In some cases, the wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, communication in 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 in some cases to communicate over logical channels. The Medium Access Control (MAC) layer can perform priority handling and multiplexing of logical channels onto transport channels. The MAC layer can also use Hybrid Automatic Repeat reQuest (HARQ) to provide retransmissions in the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide establishment, configuration, and maintenance of an RRC connection between the UE 115 and the base station 105 or the core network 130 that supports radio bearers for user plane data. In the Physical (PHY) layer, transport channels can be mapped to physical channels.

[0064]

[0073] The wireless communication system 100 can support a feature referred to as operation on multiple cells or carriers, i.e., carrier aggregation (CA) or multi-carrier operation. A carrier can also be referred to as a component carrier (CC), layer, channel, etc. The terms "carrier", "component carrier", and "channel" can be used interchangeably herein. The UE 115 can be composed of multiple downlink CCs and one or more uplink CCs for carrier aggregation. Carrier aggregation can be used with both Frequency Division Duplexing (FDD) component carriers and Time Division Duplexing (TDD) component carriers.

[0065]

[0074] In some cases, the wireless communication system 100 may utilize an extended component carrier (eCC). The eCC may be characterized by one or more features including a wider bandwidth, a shorter symbol duration, a shorter TTI, and a modified control channel configuration. In some cases, the eCC may be associated with a dual connectivity configuration or a carrier aggregation configuration (e.g., when multiple serving cells have sub-optimal or non-ideal backhaul links). The eCC may also be configured for use in unlicensed spectrum or shared spectrum (where one or more operators are permitted to use the spectrum). The eCC characterized by a wide bandwidth may include one or more segments that can be utilized by a UE 115 that cannot monitor the entire bandwidth (e.g., to save power) or prefers to use a limited bandwidth.

[0066]

[0075] In some cases, the eCC may utilize a symbol duration different from other CCs, which may include the use of a reduced symbol duration compared to the symbol duration of other CCs. The shorter symbol duration may be associated with an increased SCS. The TTI in the eCC may consist of one or more symbols. In some cases, the TTI duration (i.e., the number of symbols in the TTI) may be variable. In some cases, the eCC may utilize a symbol duration different from other CCs, which may include the use of a reduced symbol duration compared to the symbol duration of other CCs. The shorter symbol duration is associated with an increased SCS. A device such as a UE 115 or a base station 105 that utilizes the eCC may transmit a wideband signal (e.g., 20, 40, 60, 80 MHz, etc.) with a reduced symbol duration (e.g., 16.67 microseconds). The TTI in the eCC may consist of one or more symbols. In some cases, the TTI duration (i.e., the number of symbols in the TTI) may be variable.

[0067]

[0076] The shared radio frequency spectrum band can be utilized in an NR shared spectrum system. For example, the NR shared spectrum can utilize any combination such as licensed spectrum, shared spectrum, and unlicensed spectrum. The flexibility of the eCC symbol duration and SCS can enable the use of eCC across multiple spectra. In some examples, in particular, through dynamic vertical (e.g., across frequencies) and horizontal (e.g., across time) sharing of resources, the NR shared spectrum can increase spectrum utilization and spectral efficiency. When operating in an unlicensed radio frequency band, wireless devices such as base station 105 and UE 115 can utilize a listen-before-talk (LBT) procedure to ensure that the channel is clear before transmitting data. In some cases, operation in the unlicensed band can be based on a CA configuration together with the CC operating in the licensed band. Operation in the unlicensed spectrum can include downlink transmission, uplink transmission, or both. Duplexing in the unlicensed spectrum can be based on FDD, TDD, or a combination of both.

[0068]

[0077] The wireless communication system 100 can operate in the extremely high frequency (UHF) band that uses a frequency band from 300 MHz to 3 GHz. Since the wavelength in this band ranges approximately from 1 decimeter to 1 meter, it can also be known as the decimeter band. UHF waves can mainly propagate by line of sight and can be blocked by buildings and environmental features. However, the waves can penetrate walls well enough to provide services to the UE 115 located indoors. Transmission of UHF waves is characterized by a smaller antenna and a shorter range (e.g., less than 100 km) compared to transmission using smaller frequencies (and longer waves) in the shortwave (HF) or very high frequency (VHF) parts of the spectrum. The wireless communication system 100 can also operate in the super high frequency (SHF) band that uses a frequency band from 3 GHz to 30 GHz, which is also known as the centimeter band. In some cases, the wireless communication system 100 can also utilize the extremely high frequency (EHF) part of the spectrum (e.g., from 30 GHz to 300 GHz), which is also known as the millimeter band. Systems using this band can be called millimeter wave (mmW) systems. Thus, EHF antennas can be even smaller and can be arranged at closer intervals than UHF antennas. In some cases, this can facilitate the use of antenna arrays within the UE 115 (e.g., for directive beamforming). However, EHF transmission may experience even greater atmospheric attenuation than UHF transmission and can have a shorter range. The techniques disclosed herein can be employed across transmissions using one or more different frequency bands.

[0069]

[0078] The wireless communication system 100 may support millimeter wave (mmW) communication between the UE 115 and the base station 105. Devices operating in the mmW, SHF, and EHF bands may have multiple antennas to enable beamforming. Beamforming may also be employed outside of these frequency bands (e.g., in any scenario where increased cellular coverage is desired). That is, the base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with the UE 115. Beamforming (which may also be referred to as spatial filtering or directional transmission) is a signal processing technique that may be used at a transmitter (e.g., the base station 105) to steer or shape the entire antenna beam in the direction of a target receiver (e.g., the UE 115). This may be achieved by combining the elements in an antenna array such that the transmitted signals at a particular angle experience constructive interference while others experience destructive interference. For example, the base station 105 may have an antenna array with a number of rows and columns of antenna ports that the base station 105 uses for beamforming in its communication with the UE 115. The signal may be transmitted multiple times in different ways (e.g., each transmission may be beamformed differently). The mmW receiver (e.g., the UE 115) may try multiple beams (e.g., antenna sub-arrays) while receiving the signal. Each of these beams may be referred to as a receive beam in the aspects of the present disclosure.

[0070]

[0079] A multiple-input multiple-output (MIMO) wireless system uses a transmission scheme between a transmitter (e.g., base station 105) and a receiver (e.g., UE 115), where both the transmitter and the receiver are equipped with multiple antennas. In some cases, the antennas of base station 105 or UE 115 can be positioned within one or more antenna arrays, which can support beamforming or MIMO operations. One or more base station antennas or antenna arrays can be collocated with an antenna assembly, such as an antenna tower. In some cases, the antennas or antenna arrays associated with base station 105 can be located in different geographical locations. That is, base station 105 can use multiple antennas or antenna arrays to perform beamforming operations for directional communication with UE 115.

[0071]

[0080] Synchronization (e.g., cell acquisition) can be performed using synchronization signals or channels transmitted by a network entity (e.g., base station 105). The base station can transmit an SS block including a discovery reference signal. The SS block can include a PSS, an SSS, and / or a PBCH. A UE 115 attempting to access the wireless network can perform an initial cell search by detecting the PSS from the base station 105. The PSS can enable symbol timing synchronization and can indicate a physical layer identification value. The PSS can be utilized to acquire timing, frequency, and a physical layer identifier. The UE 115 can then receive the SSS from the base station 105. The SSS can enable radio frame synchronization and can provide a cell group identification value. The cell group identification value can be combined with the physical layer identifier to form a physical cell identifier (PCID) that identifies the cell. The SSS can also enable detection of the multiple antenna mode and the cyclic prefix (CP) length. The SSS can be used to acquire other system information (e.g., subframe index). The PBCH can be used to acquire additional system information (e.g., bandwidth, frame index, etc.) required for acquisition. For example, the PBCH can carry a master information block (MIB) and one or more system information blocks (SIBs) for a given cell.

[0072]

[0081] In a deployment using mmW transmission frequencies (e.g., in NR), multiple SS blocks can be transmitted in different directions using beam sweeping during an SS burst, and the SS burst can be transmitted periodically according to an SS burst set. The duration of the SS burst can be referred to herein as an SS burst set measurement window. The number of directions in which an SS block is sent during an SS burst (e.g., during an SS burst set measurement window of 4 or 5 ms) can vary in different configurations and can also be a function of the bandwidth in which base station 105 is operating. For example, an SS block can be transmitted (e.g., beamformed) in four different directions when base station 105 is operating in the 0 - 3 GHz range, in eight different directions when the base station is operating in the 3 - 6 GHz range, and in up to 64 different directions when the base station is operating at a frequency higher than 6 GHz.

[0073]

[0082] Time intervals in LTE or NR can be expressed as multiples of a basic time unit (which can be a sampling period of T S = 1 / 30,720,000 seconds). Time resources can be identified by a system frame number (SFN) in the range from 0 to 1023, and a 10 ms (T = 307200T s) can be configured according to the length of the radio frame. Each frame may include 10 sub-frames numbered from 0 to 9 with a duration of 1 ms each. The sub-frame can be further divided into two 5-ms slots, each of which includes 6 or 7 modulated symbol periods (depending on the length of the cyclic prefix added to each symbol). Excluding the cyclic prefix, each symbol includes 2048 sample periods. In NR, the symbol interval in the time domain can vary together with the tone interval (or SCS) in the frequency domain. For example, an SCS of 240 kHz may correspond to a symbol duration of approximately 4 μs, and an SCS of 30 kHz may correspond to a symbol duration of approximately 33 μs. In some cases, the sub-frame can be the minimum scheduling unit, also known as the TTI. In other cases, the TTI can be dynamically selected (e.g., in a short TTI burst or in a selected component carrier using a short TTI) or may be shorter than the sub-frame.

[0074]

[0083] A resource element can be composed of one symbol period and one sub-carrier (e.g., a 15 KHz frequency range). A resource block may include 12 consecutive sub-carriers in the frequency domain and, for the normal cyclic prefix in each orthogonal frequency division multiplexing (OFDM) symbol, may include 7 consecutive OFDM symbols in the time domain (1 slot), or 84 resource elements. The number of bits carried by each resource element can depend on the modulation scheme (the symbol configuration that can be selected during each symbol period). Therefore, the higher the number of resource blocks received by the UE and the more advanced the modulation scheme, the higher the data rate can be.

[0075]

[0084] As indicated above, in some cases, multiple BWPs can be configured for the communication link 125 between the base station 105 and the UE 115. The base station 105 can provide an indication of the activated BWP to the UE 115 through a downlink control information (DCI) transmission that may or may not include a grant of resources for the BWP. In some cases, the UE 115 can establish a connection with the base station 105 where one or more CCs can be composed of one or more BWPs and the CC can be activated through the activation of one or more BWPs configured for the CC. Such a CC can be deactivated through the deactivation of each BWP configured for the CC.

[0076]

[0085] In some cases, the SS blocks and downlink transmissions within the configured BWP employed by the wireless communication system 100 can be associated with mixed transmission attributes (e.g., SCS, beam direction, etc.). That is, different (e.g., mixed) transmission attributes can be associated with SS block transmissions and other downlink transmissions (e.g., control transmissions such as PDCCH, or data transmissions such as PDSCH, CSI-RS) within the BWP. Techniques for handling such mixed transmission attributes (e.g., in an FDM scenario) are described in more detail with reference to the following drawings.

[0077]

[0086] Figure 2 illustrates an example of a wireless communication system 200 that supports FDM for BWP transmission with hybrid attributes according to an aspect of the present disclosure. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a base station 105-a and a UE 115-a, each of which may be an example of a corresponding device described with reference to FIG. 1. In this example, the base station 105-a may carry downlink communication 215 via one or more transmission beams 205. The UE 115-a may receive such communication via one or more reception beams 210. The downlink communication 215 may include one or more SS blocks 225, as well as downlink transmission 220 (e.g., downlink data or downlink signals such as PDSCH, PDCCH, CSI-RS, etc. within a configured BWP). In some cases, the downlink communication 215 may employ FDM. Each of the additional SS blocks 225 and downlink transmissions 220 may be associated with several transmission attributes (e.g., SCS, beam direction associated with the transmission beam 205, beam direction associated with the reception beam 210, etc.). In some cases, the transmission or reception beam direction may correspond to a beam identifier (ID).

[0078]

[0087] The base station 105-a may constitute one or more SS blocks 225 for transmission to the UE 115-a for cell acquisition and timing synchronization procedures (e.g., to assist the UE 115-a in synchronizing with the cell associated with the base station 105-a). For example, the SS block 225 may include signals (e.g., PSS, SSS, and PBCH) that assist the UE 115-a in acquiring the timing of the cell. In some cases, the base station 115-a may transmit multiple SS blocks 225, e.g., in an SS burst that persists for a particular duration. The SS blocks may be transmitted in different directions at different times using beamforming, e.g., in a beam sweeping pattern (e.g., a beam sweeping pattern that includes transmission beams 205-a, 205-b, 205-c, 205-d, etc.). However, such an SS burst may target multiple UEs 115 (e.g., a particular SS block 225 associated with the transmission beam 205-c may target the UE 115-a, as further described with reference to FIG. 3). In some examples, the SS burst or SS block 225 may be transmitted periodically so that the UE 115 can maintain synchronization with the base station 105 over time.

[0079]

[0088] In one example, UE115-a may form receive beams 210-a and 210-b. In some cases, receive beams 210-a and 210-b may each receive signals sent via one or more transmit beams 205. Since signals sent via one transmit beam 205 may experience different path losses and phase shifts on their way to each antenna of UE115-a, and since each receive beam 210-a and 210-b may apply different weights to the antennas of UE115-a, the signals received over one receive beam 210 may have different signal characteristics than the signals received over different receive beams 210. UE115-a may select transmit beam 205 and receive beam 210 based on the received signal quality. The transmit beam 205 and the corresponding receive beam 210 may be referred to as a beam pair. For example, in some cases, base station 105-a may repeat transmissions over multiple transmit beams 205 (e.g., in all directions), and UE115-a may report the beam that can be received (e.g., via receive beam 210-a or 210-b) with a signal quality above a threshold by the UE, or may report the strongest received beam. These transmit beams 205 may be broadcast beams directed to one or more UEs 115, and in some cases, each may be associated with an SS block 225.

[0080]

[0089] Furthermore, base station 105-a may utilize one or more portions of the channel frequency bandwidth (e.g., associated with downlink communication 215), which in some cases may be referred to as a BWP for downlink transmission 220. The BWP may be configured according to, for example, the size of the channel frequency bandwidth, the size of the downlink transmission 220, the capabilities of UE115-a or other UEs 115, etc.

[0081]

[0090] The SS block 225 and the downlink transmission 220 can be sent according to some transmission attributes including, for example, SCS, beam direction (e.g., associated with the transmission and / or reception of the SS block 225 or the downlink transmission 220), etc. For example, the SS block 225 can be sent according to an SCS of 15 kHz or 30 kHz for an operating frequency below 6 GHz and according to an SCS of 120 kHz or 240 kHz for an operating frequency above 6 GHz. The UE 115 can identify the transmission attributes via implicit or explicit information. For example, the UE 115 can be cross-carrier scheduled to a carrier and receive information about the transmission attributes of the carrier before receiving the SS block. Additionally or alternatively, the UE 115 can monitor a carrier for the SS block according to one or more transmission attributes and thus implicitly detect the transmission attributes by detecting the SS block. Additionally, the downlink transmission 220 (e.g., PDSCH, PDCCH, CSI-RS, etc., transmitted within one or more configured BWPs) can be associated with different transmission attributes. For example, the downlink transmission 220 can be sent according to a different SCS (e.g., compared to the SCS of the transmitted SS block 225), a different transmission beam 205, a different reception beam 210, etc. Generally, the transmission attributes for the SS block can be called SS block transmission attributes, the transmission attributes included in the configuration for the BWP of the carrier can be called BWP transmission attributes, and the transmission attributes associated with a channel or a signal can be called channel or signal attributes. A set of transmission attributes can be called a numerology. The techniques described herein provide an efficient handling or management of FDM communication in a scenario where the SS block 225 and other downlink transmissions 220 are associated with a mixed numerology (e.g., transmission parameters, characteristics, etc.).

[0082]

[0091] For example, base station 105-a may identify a configuration for a (e.g., carrier) BWP that includes one or more BWP transmission attributes for transmission within the BWP. That is, base station 105-a may configure transmission attributes for downlink transmission 220 within the BWP. For example, base station 105-a may associate a SCS with the configured BWP, or may configure a channel or signal for transmission via the BWP having the transmission attributes. Additionally or alternatively, base station 105-a may associate a beam direction (e.g., transmission beam 205, reception beam 210, or beam ID associated with an active beam pair) with the configured BWP.

[0083]

[0092] Furthermore, UE 115 can identify one or more BWP transmission attributes based on, for example, a BWP configuration that can be determined by the UE from the PBCH payload included as part of the transmitted SS block. Thus, the BWP transmission attributes can be identified based on signals such as SS block transmissions. The base station 105-a can transmit a grant for the downlink transmission 220 to the UE 115-a. In some examples, the grant can indicate resources that temporally overlap with the SS block 225 targeted at the UE 115-a (e.g., FDM). The UE 115-a can identify the SS block 225 resources (e.g., the symbol period in which the SS block 225 is transmitted) via the remaining minimum system information (RMSI) or the RRC configuration, and can identify the timing of the downlink transmission 220 via the received grant. If the time-overlapping downlink transmission 220 and the SS block 225 are associated with the same transmission attributes (e.g., the same SCS), FDM may not pose any problems for reception by the UE 115. However, if the downlink transmission 220 and the SS block 225 are associated with different or mixed transmission attributes, some UEs 115 may not be able to process FDM signals with mixed attributes. For example, a UE 115 receiving multiple signals FDM'd at different SCSs may need to perform separate inverse discrete Fourier transform (IDFT) or inverse fast Fourier transform (IFFT) operations to demodulate the different signals. Some UEs may not have sufficient processing resources to perform parallel operations. As will be described in more detail below with reference to FIGS. 3A-3C, techniques for dealing with such FDM (e.g., having mixed transmission attributes) may be employed. In yet other cases, the UE may not support such FDM (e.g., resources of the downlink transmission 220 that overlap with the SS block 225 in time), and the PDSCH grant for the overlapping resources may be rejected.

[0084]

[0093] In some cases, the transmission attributes can be configured based on UE capabilities indication. For example, base station 105-a can select transmission attributes (e.g., SS block transmission attributes and / or BWP transmission attributes) for downlink transmission 220 based on the capability message received from UE115-a. In some cases, the capability message can indicate whether the UE supports FDM, supports FDM with hybrid transmission attributes, supports TDM of transmission attributes within the permission, etc. Thus, some of the techniques described herein can be selected or excluded based on such capabilities indicated by the UE. For example, if the UE indicates that it does not support FDM reception across different beam directions, the base station can use the same beam direction (e.g., beam ID) for both the SS block 225 where FDM is used and the downlink transmission 220. As another example, if the UE indicates that it cannot support FDM with mixed transmission attributes, base station 105 can use the SS block transmission attributes (with possible TDM of the transmission attributes within the downlink transmission 220) to transmit the downlink transmission 220 that is FDM in the SS block. In cases where TDM is used for mixed beams within the downlink transmission 220 (e.g., using different transmission beams 205 and / or reception beams 210), separate demodulation reference signals (DMRS) can be used in each of the TDM'd parts (e.g., to enable channel estimation for each part).

[0085]

[0094] In some cases, the downlink transmission 220 may not be FDM'd with the SS block 225 for a given UE115 (e.g., if it indicates that the UE115 is not capable of supporting FDM). In such cases, the base station 105-a may not transmit the downlink transmission 220 (e.g., PDSCH) during any overlapping symbol periods in which the SS block 225 is scheduled. Such a UE115 may reject any grant for downlink transmission that indicates that the transmission will overlap with the SS block that it is expected to monitor. For example, the UE115 may treat the grant as having been decoded incorrectly (e.g., an incorrect CRC pass during PDCCH decoding).

[0086]

[0095] Although the above example has been described with respect to downlink transmission (i.e., such that the transmission beam 205 originates at the base station 105-a), it should be understood that similar considerations for uplink transmission are within the scope of the present disclosure.

[0087]

[0096] Figures 3A, 3B, and 3C illustrate examples 300-a, 300-b, and 300-c of FDM for BWP transmission with hybrid attributes, according to aspects of the present disclosure. The examples of FIGS. 3A-3C may implement aspects of wireless communication system 100 and wireless communication system 200. Generally, the transmission attributes for an SS block may be referred to as SS attributes 305, and the transmission attributes included in the configuration for a BWP of a carrier (e.g., or the transmission attributes for transmission within a BWP) may be referred to as BWP attributes 310. The techniques described herein provide three examples for the efficient handling or management of FDM communication in scenarios where SS block 315 and other downlink transmissions 320 are associated with hybrid transmission attributes (e.g., transmission parameters, characteristics, etc. that may refer to SCS, transmission beam ID, reception beam ID, beam pair ID, etc.). In some cases, downlink transmissions may be multiplexed with SS blocks according to a scheme or pattern (e.g., FDM and / or TDM). In examples 300-a, 300-b, and 300-c, frequency (e.g., kHz) may generally be represented along the vertical axis, and time (e.g., seconds) may generally be represented along the horizontal axis.

[0088]

[0097] FIG. 3A shows an example 300-a in which a downlink transmission 320-a is scheduled within a BWP 325-a (e.g., via the base station 105 or a permission from the base station 105). The downlink transmission 320-a is FDM with an SS block 315-a for a set 330-a of time resources. In some cases, the set 330-a of time resources may be referred to as an FDM duration. According to the technique shown in example 300-a, the entire downlink transmission 320-a may be transmitted using one or more SS attributes 305 (e.g., by the base station 105). That is, both the set 330-a of time resources (e.g., the FDM portion) of the downlink transmission 320-a and the remaining portion (e.g., the remaining resources of the downlink transmission 320-a that do not temporally overlap with the SS block 315-a) may be associated with the SS attribute 305. For example, since the FDM region may be associated with only the SS attribute 305, there may be no hybrid numerology associated with the FDM region (e.g., the set 330-a of time resources). Further, a subsequent downlink transmission 320-b may also be scheduled in the BWP 325-a (e.g., at a time following the downlink transmission 320-a). In some cases, the downlink transmission 320-b may be a subsequent downlink transmission for the same UE that does not temporally overlap with the SS block 315-a, and thus, the DL BWP attribute 310 may be used. Additionally, in some cases, the BWP 325-a may include additional transmissions (not shown) for different UEs, some of which may be FDM with the downlink transmission 320-a. The base station may insert a guard band in the frequency region between FDM transmissions having some hybrid attributes (e.g., the guard band may be inserted for FDM of hybrid SCS transmissions rather than between FDM of hybrid beam directions, etc.).

[0089]

[0098] FIG. 3A also shows an SS block (dashed line) that may exist and that is not targeted at a UE receiving downlink transmission 320-a (e.g., sent by the serving base station). As described above, such an SS block that is not directed at the relevant UE does not contribute to the FDM scenario and is not considered in the selection of transmission attributes for downlink transmission 320 directed at the UE. That is, SS block 315-b may be targeted at or sent to some other neighboring UEs. Although SS block 315-b may overlap in time with downlink transmission 320-b, downlink transmission 320-b may still be associated with BWP attribute 310 (e.g., thus, the technique of example 300-a applied to downlink transmission 320-a may not be applicable to downlink transmission 320-b as a UE receiving both downlink transmission 320-a and downlink transmission 320-b may not be monitoring SS block 315-b). In one example, the technique described with reference to example 300-a may be selected when the UE indicates (e.g., via a capability message) that it supports FDM but does not support FDM with a hybrid attribute (e.g., hybrid numerology).

[0090]

[0099] FIG. 3B illustrates example 300-b where downlink transmission 320-c is scheduled within BWP 325-b (e.g., via base station 105 or permission from base station 105). Downlink transmission 320-c is FDM with SS block 315-c for a set of time resources 330-b. In some cases, the set of time resources 330-b may be referred to as the FDM duration. According to the technique shown in example 300-b, the portion of downlink transmission 320-c associated with the set of time resources 330-b (e.g., the FDM portion) may be associated with SS attribute 305. However, the remaining portion (e.g., the remaining resources of downlink transmission 320-c that do not temporally overlap with SS block 315-c) may be associated with BWP attribute 310. Thus, since the FDM region can only be associated with SS attribute 305, there can be no hybrid numerology associated with the FDM region (e.g., the set of time resources 330-b). However, a TDM region of hybrid numerology exists within downlink transmission 320-c. Further, a subsequent downlink transmission 320-d may also be scheduled in BWP 325-b (e.g., at a time following downlink transmission 320-c). As illustrated in FIG. 3B, downlink transmission 320-d may follow a TDM and FDM scheme combined with SS block 315-c.

[0091]

[0100] Figure 3B also shows SS blocks (dashed lines) that may exist and are not targeted at the UE receiving downlink transmission 320-c (e.g., sent by the serving base station). As described above, such SS blocks not directed to the relevant UE do not contribute to the FDM scenario or the selection of transmission attributes for the downlink transmission 320 directed to the UE, etc. That is, the illustrated dashed-line SS blocks may target or be transmitted to some other adjacent UEs. Such SS blocks targeting other UEs may overlap in time with downlink transmission 320-d, but downlink transmission 320-d may still be associated with the BWP attribute 310 (e.g., thus, the technique of example 300-b applied to downlink transmission 320-c may not be applicable to downlink transmission 320-d because a UE receiving both downlink transmission 320-c and downlink transmission 320-d may not monitor SS blocks targeting other UEs). In one example, the technique described with reference to example 300-b may be selected when the UE indicates (e.g., via a capability message) that it supports TDM mixed numerology and FDM but does not support FDM in mixed numerology. Further, in example 300-b, FDM mixed numerology may not be supported, but TDM mixed numerology (e.g., within a single downlink packet (e.g., within downlink transmission 320-c)) may be utilized. Note that some UEs may have limited capabilities and may not be able to receive TDM mixed numerology. When the scheme of Figure 3B is used, such UEs reject any grants indicating data transmissions that only partially overlap with the SS block, but accept grants indicating data transmissions that fully overlap with or do not overlap at all with the SS block. As described above, the SS blocks in this context refer only to the SS blocks that the UE is expected to receive or monitor.

[0092]

[0101] Figure 3C shows example 300-c where downlink transmission 320-e is scheduled within BWP 325-c (e.g., via base station 105 or with permission from base station 105). Downlink transmission 320-e is FDM with SS block 315-d for a set of time resources 330-c. In some cases, the set of time resources 330-b can be referred to as the FDM duration. According to the technique shown in example 300-c, the portion of downlink transmission 320-e associated with the set of time resources 330-c (e.g., the FDM portion), as well as the remaining portion (e.g., the remaining resources of downlink transmission 320-e that do not overlap with SS block 315-d), can be associated with BWP attribute 310. The technique shown in example 300-c can result in a mixed numerology associated with the FDM region (e.g., the set of time resources 330-c) since the FDM region can be associated with both SS attribute 305 and BWP attribute 310. Further, subsequent downlink transmission 320-f can also be scheduled in BWP 325-c (e.g., at a time following downlink transmission 320-e). As illustrated in Figure 3C, downlink transmission 320-f can follow a combined TDM and FDM scheme with respect to SS block 315-d.

[0093]

[0102] Figure 3C also shows a possible SS block (dashed line) that is not targeted at a UE receiving downlink transmission 320-e or 320-f (e.g., sent by the serving base station). As explained above, such an SS block that is not directed at the associated UE does not contribute to either the FDM scenario or the transmission attribute selection for downlink transmission 320 directed at the UE. In one example, the technique described with reference to example 300-c can be selected when the UE indicates (e.g., via a capability message) that it supports FDM with mixed numerology. In some cases, the base station can also ensure sufficient guard bands between FDM'ed mixed numerologies (e.g., the guard bands can be inserted for FDM of mixed SCS transmissions rather than between FDM of mixed beam directions, etc.).

[0094]

[0103] Figure 4 shows a block diagram 400 of a wireless device 405 that supports FDM for BWP transmission with hybrid attributes, according to an aspect of the present disclosure. The wireless device 405 can be an example of an aspect of the UE 115 as described herein. The wireless device 405 can include a receiver 410, a UE communication manager 415, and a transmitter 420. The wireless device 405 can also include a processor. Each of these components can be in communication with each other (e.g., via one or more buses).

[0095]

[0104] The receiver 410 can 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 FDM for BWP transmission with hybrid attributes, etc.). The information can be passed to other components of the device. The receiver 410 can be an example of an aspect of the transceiver 735 described with reference to FIG. 7. The receiver 410 can utilize a single antenna or it can utilize a set of antennas.

[0096]

[0105] UE communication manager 415 can be an example of the aspects of UE communication manager 715 described with reference to FIG. 7. At least some of the UE communication manager 415 and / or its various sub-components can be implemented in hardware, software executed by a processor, firmware, or any combination thereof. When implemented in software executed by a processor, at least some of the functions of the communication manager 415 or its various sub-components can 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 of these designed to perform the functions described in this disclosure. At least some of the UE communication manager 415 and / or its various sub-components can be physically located in various locations, including being distributed such that portions of the functionality are implemented in different physical locations by one or more physical devices.

In other examples, at least some of the communication manager 415 or its various sub-components can be combined with one or more other hardware components according to various aspects of this disclosure, including, but not limited to, I / O components, transceivers, network servers, another computing device, one or more other components described in this disclosure, or combinations thereof.

[0097]

[0106] In the first example, the UE communication manager 415 may identify a configuration for a carrier's BWP. The configuration may include a first value for transmission attributes for transmission within the BWP. The UE communication manager 415 may receive a grant for downlink transmission. In some cases, the downlink transmission may be scheduled for a set of resources in a BWP that temporally overlaps with the SS block for the carrier. The SS block may be transmitted using a second value for transmission attributes. The UE communication manager 415 may then receive the downlink transmission, where receiving includes applying the second value for transmission attributes for at least a portion of the set of resources.

[0098]

[0107] In the second example, the UE communication manager 415 receives a synchronization signal block for a carrier, the synchronization signal block being associated with synchronization signal block transmission attributes and identifying one or more BWP transmission attributes for transmission within the carrier's BWP, and based on the synchronization signal block transmission attributes and the one or more BWP transmission attributes, may receive transmissions across the carrier's BWP, where the transmissions may be multiplexed with the synchronization signal block according to a pattern selected from a plurality of predefined multiplexing schemes including a time division multiplexing scheme and a frequency division multiplexing scheme.

[0099]

[0104]

[0113] In a second example, the BWP manager 525 can receive a synchronization signal block for a carrier, and the synchronization signal block is associated with synchronization signal block transmission attributes and can identify one or more BWP transmission attributes for transmission within the BWP of the carrier.

[0105]

[0114] In the first example, the grant manager 530 may receive a grant for downlink transmission, and the downlink transmission is scheduled for a set of resources in a BWP that temporally overlaps with the SS block for the carrier, and the SS block is transmitted using a second value for the transmission attribute.

[0106]

[0115] In the first example, the transmission attribute manager 535 may receive a downlink transmission, where receiving includes applying a second value for the transmission attribute for at least a portion of the set of resources. In some cases, receiving a downlink transmission includes applying a second value for the transmission attribute for all of the set of resources. In some cases, receiving a downlink transmission includes applying a first value for the transmission attribute for a first portion of the set of resources that does not temporally overlap with the SS block and a second value for the transmission attribute for a second portion of the set of resources that temporally overlaps with the SS block.

[0107]

[0116] In the second example, the transmission attribute manager 535 may receive transmissions across the carrier's BWP based on the synchronization signal block transmission attribute and one or more BWP transmission attributes, where the transmissions may be multiplexed with the synchronization signal block according to a pattern selected from a plurality of predefined multiplexing schemes including a time division multiplexing scheme and a frequency division multiplexing scheme.

[0108]

The UE communication manager 615 can include a BWP manager 620, a grant manager 625, and a transmission attribute manager 630. Each of these modules can communicate with each other directly or indirectly (e.g., via one or more buses).

[0110]

[0119] The BWP manager 620 can identify a configuration for a carrier's BWP, and the configuration includes a first value for transmission attributes for transmission within the BWP. In some cases, the transmission attributes include the SCS. In some cases, the transmission attributes include a transmission beam direction or a reception beam direction.

[0111]

[0120] Additionally or alternatively, the BWP manager 620 can receive a synchronization signal block for the carrier, and the synchronization signal block is associated with synchronization signal block transmission attributes. In some cases, the BWP manager 620 can identify one or more BWP transmission attributes for transmission within the carrier's BWP. In some cases, the synchronization signal block transmission attributes include a first SCS, and the one or more BWP transmission attributes include a second SCS. In some cases, the first SCS and the second SCS are different. In some cases, the one or more BWP transmission attributes include a transmission beam direction or a reception beam direction.

[0115]

The device 705 may include, or be an example of, components such as the wireless device 405, the wireless device 505, or the UE 115 as described above with reference to FIGS. 4 and 5. The device 705 may include components for bidirectional voice and data communication including components for transmitting and receiving communication, including a communication manager 715, a processor 720, a memory 725, software 730, a transceiver 735, an antenna 740, and an I / O controller 745.

[0118]

[0127] The software 730 may include code for implementing aspects of the present disclosure, including code for supporting FDM for BWP transmission with mixed attributes. The software 730 may be stored in a non-transitory computer-readable medium such as system memory or other memory. In some cases, the software 730 may not be directly executable by the processor but may cause the computer to perform the functions described herein (e.g., when compiled and executed).

[0119]

[0128] As described above, the transceiver 735 can communicate bidirectionally via one or more antennas, wired or wireless links. For example, the transceiver 735 can represent a wireless transceiver and communicate bidirectionally with another wireless transceiver.

Each of these components can be in communication with each other (e.g., via one or more buses).

[0123]

[0132] The receiver 810 can 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 FDM for BWP transmission with mixed attributes, etc.). The information can be passed to other components of the device. The receiver 810 can be an example of an aspect of the transceiver 1135 described with reference to FIG. 11. The receiver 810 can utilize a single antenna or it can utilize a set of antennas.

[0124]

[0133] The base station communication manager 815 can be an example of the embodiment of the base station communication manager 1115 described with reference to FIG. 11. At least some of the base station communication manager 815 and / or its various sub-components can be implemented in hardware, software executed by a processor, firmware, or any combination thereof. When implemented in software executed by a processor, at least some of the functions of the base station communication manager 815 and / or its various sub-components can be executed by a general-purpose processor, DSP, ASIC, 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. The base station communication manager 815 and / or at least some of its various sub-components can be physically located in various locations, including being distributed such that portions of the functionality are implemented in different physical locations by one or more physical devices. In some examples, the base station communication manager 815 and / or at least some of its various sub-components can be distinct and different components according to various aspects of this disclosure. In other examples, the base station communication manager 815 and / or at least some of its various sub-components can be combined with one or more other hardware components including, but not limited to, I / O components, transceivers, network servers, other computing devices, one or more other components described in this disclosure, or combinations thereof, according to various aspects of this disclosure.

[0125]

[0134] The base station communication manager 815 may identify a configuration for a carrier's BWP, and the configuration may include a first value for transmission attributes for transmission within the BWP. The base station communication manager 815 may transmit a permission for a first downlink transmission in the BWP to a first UE. In some cases, the first downlink transmission may be scheduled for a first set of resources that temporally overlap with an SS block for the carrier (e.g., the SS block may be transmitted using a second value for transmission attributes). The base station communication manager 815 may then transmit the first downlink transmission, where transmitting includes applying a second value for transmission attributes for at least a portion of the first set of resources.

[0126]

[0135] The base station communication manager 815 may identify a configuration for a carrier's BWP, and the configuration may include a first value for transmission attributes for transmission within the BWP. The base station communication manager 815 may transmit a permission for a first downlink transmission in the BWP to a first UE, and the first downlink transmission is scheduled for a first set of resources that temporally overlap with an SS block for the carrier (e.g., the SS block is transmitted using a second value for transmission attributes). The base station communication manager 815 may then transmit the first downlink transmission, where transmitting includes applying a first value for transmission attributes for the first set of resources and inserting a guard band in the frequency domain between the first downlink transmission and the SS block.

[0127]

[0136] Additionally or alternatively, the base station communication manager 815 may transmit to the UE a synchronization signal block for a carrier, the synchronization signal block being associated with synchronization signal block transmission attributes and configuring one or more BWP transmission attributes for transmission within the BWP of the carrier. The base station communication manager 815 may transmit to the UE transmissions across the BWP of the carrier based on the synchronization signal block transmission attributes and the one or more BWP transmission attributes, the transmissions being multiplexed with the synchronization signal block according to a pattern selected from a plurality of predefined multiplexing schemes including a time division multiplexing scheme and a frequency division multiplexing scheme.

[0128]

[0137] As a further addition or alternative, the base station communication manager 815 may also transmit to the UE a synchronization signal block for a carrier, the synchronization signal block being associated with synchronization signal block transmission attributes and configuring one or more BWP transmission attributes for transmission within the BWP of the carrier. The base station communication manager 815 may transmit downlink transmissions to the UE across the BWP of the carrier based on the synchronization signal block transmission attributes and the one or more BWP transmission attributes, the downlink transmissions being multiplexed with the synchronization signal block according to a pattern selected from a plurality of predefined multiplexing schemes including a time division multiplexing scheme and a frequency division multiplexing scheme, the pattern including a guard band inserted in the frequency domain between the downlink transmissions and the synchronization signal block.

[0129]

[0138] The transmitter 820 may transmit signals generated by other components of the device. In some examples, the transmitter 820 may be collocated with the receiver 810 in a transceiver module. For example, the transmitter 820 may be an example of the aspects of the transceiver 1135 described with reference to FIG. 11. The receiver 820 may utilize a single antenna or it may utilize a set of antennas.

CDMA2000 and UMB are described in documents from a group named the "3rd Generation Partnership Project 2" (3GPP2). The techniques described herein may be used with the systems and wireless technologies described above, as well as with other systems and wireless technologies. Aspects of an LTE or NR system may be described for purposes of example, and the LTE or NR terminology may be used in most of the description, while the techniques described herein are applicable beyond LTE or NR applications.

[0191]

[0200] Macro cells generally cover a relatively large geographical area (e.g., several kilometers in radius) and may enable unrestricted access by a UE 115 subscribed to a network provider. 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 a different (e.g., licensed, unlicensed, etc.) frequency band as the macro cell. Small cells may include picocells, femtocells, and microcells according to various examples. A picocell may cover, for example, a small geographical area and may enable unrestricted access by a UE 115 subscribed to a network provider. A femtocell may also cover a small geographical area (e.g., a home) and may provide restricted access by a UE 115 associated with the femtocell (e.g., a UE 115 in a closed subscriber group (CSG), a UE 115 for a user in the home, etc.). The eNB for a macro cell may be referred to as a macro eNB. The eNB for a small cell may be called a small cell eNB, a pico eNB, a femto eNB, or a home eNB. An eNB may support one or more (e.g., two, three, four, etc.) cells and may also support communication using one or more component carriers.

[0192]

[0201] One or more wireless communication systems 100 described herein may support synchronous or asynchronous operation. In the case of synchronous operation, multiple base stations 105 may have similar frame timings, and transmissions from different base stations 105 may be approximately aligned in time. In the case of asynchronous operation, multiple base stations 105 may have different frame timings, and transmissions from different base stations 105 may not be aligned in time. The techniques described herein may be used for either synchronous or asynchronous operation.

[0193]

[0202] The information and signals described in this specification can be represented using any of a variety of different technologies and techniques. For example, the data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the above description can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, optical fields or optical particles, or any combination thereof.

[0194]

[0203] The various exemplary blocks and modules described in connection with the disclosure herein can be implemented or performed using a general-purpose processor, DSP, ASIC, FPGA, or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. The general-purpose processor may be a microprocessor, but in lieu thereof, the processor may be any conventional processor, controller, microcontroller, or state machine. The processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in conjunction with a DSP core, or any other such configuration).

[0195]

[0204] The functions described in this specification may be implemented in hardware, software executed by a processor, firmware, or any combination thereof. When implemented in software executed by a processor, the functions may be stored or transmitted as one or more instructions or code on a computer-readable medium. Other examples and implementations are within the scope of the present disclosure and the appended claims. For example, due to the nature of software, the functions described above may be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination of these. The features implementing the functions may also be physically located in various places, including being distributed such that parts of the functions are implemented at different physical locations.

[0196]

[0205] A computer-readable medium includes both a communication medium and a non-transitory computer storage medium that include any medium that facilitates transfer of a computer program from one location to another. The non-transitory storage medium can be any available medium that can be accessed by a general purpose or special purpose computer. By way of example and not limitation, the non-transitory computer-readable medium can comprise RAM, ROM, electrically erasable programmable read-only memory (EEPROM (registered trademark)), flash memory, compact disc (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory medium that can be used to store or carry desired program code means in the form of data structures or instructions and that can be accessed by a general purpose or special purpose computer, or a general purpose or special purpose processor. Also, any connection means can properly be called a computer-readable medium. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included in the definition of the medium. As used herein, disk and disc include CD, laser disc (registered trademark) (disc), optical disc (disc), digital versatile disc (disc) (DVD), floppy (registered trademark) disk (disk), and Blu-ray disc (disc), where disk typically magnetically reproduces data while disc optically reproduces data using a laser. Combinations of the above are also included within the scope of computer-readable media.

[0197]

[0206] As used herein, including in the claims, "or" as used in a list of items (e.g., a list of items preceded by phrases such as "at least one of" or "one or more of") indicates a disjunctive list, such that a list of at least one of, for example, A, B, or C, means A or B or C or AB or AC or BC or ABC (e.g., A and B and C). Also, as used herein, the phrase "based on" shall not be construed as a reference to a closed set of conditions. For example, an exemplary step described as "based on condition A" may be based on both condition A and condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase "based on" shall be construed in the same manner as the phrase "at least partially based on".

[0198]

[0207] In the accompanying drawings, like components or features may have the same reference label. Further, various components of the same type may be distinguished by following the reference label with a hyphen and a second label that distinguishes similar components. If only the first reference label is used in this specification, the description applies to any of the similar components having the same first reference label, regardless of the second reference label or any other subsequent reference label.

[0199]

[0208] The description set forth herein in connection with the attached drawings describes exemplary configurations and does not represent all examples that may be implemented or that are within the scope of the claims. The term "exemplary" as used herein means "serving as an example, instance, or illustration" and not "preferred" or "advantageous over other examples." The detailed description includes specific details for the purpose of providing an understanding of the described techniques. However, these techniques may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form in order to avoid obscuring the concepts of the described examples.
