Technical Field
[0003] The following relates to wireless communication, including beam indication for multiple uplink or downlink channels and reference signals. Background Technology
[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems can 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 (e.g., Long Term Evolution (LTE) systems, improved 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 can employ 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 Extended 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 also be referred to as User Equipment (UE)). Summary of the Invention

In summary, the described technology provides a user equipment (UE) with a message including Transmission Configuration Indicator (TCI) status information associated with beam information for uplink or downlink resources. For example, separate TCI status information may be indicated to the UE for uplink and downlink resources.

The multiple channels or reference signals may include multiple uplink channels or reference signals, or multiple downlink channels or reference signals, which may be based on the separate TCI status information provided to the UE. In some examples, the TCI status information may also include an indication of a source reference signal for a quasi-co-location (QCL) assumption used for the indicated channel or reference signal. Based on applying the TCI status to multiple channels and / or reference signals, the UE can determine beam information for uplink or downlink resources and can communicate with the base station accordingly.

[0050] Some wireless communication systems, such as fifth-generation (5G) New Radio (NR) systems, can use beamforming techniques to share data between devices (e.g., user equipment (UE), base stations, or other devices). In such systems, the UE can be configured with beam information (e.g., Transmission Configuration Indicator (TCI) status) indicating resources used for uplink or downlink operation on a beam set, and can also transmit information identifying various attributes indicating which beams can be used for communication. For example, signals transmitted using different beams can be correlated with each other, and a quasi-co-address (QCL) relationship between one or more transmissions or signals can refer to the relationship between the antenna ports (and corresponding signaling beams) of the respective transmissions. If two signals are quasi-co-addressed, the receiving device (e.g., the UE) can assume co-address with one signal (and its corresponding beam). The associated channel characteristics or other aspects of the measurement can also be applied when receiving a different signal. In some examples, a set of TCI states can be indicated to the UE, where a TCI state can indicate the QCL relationship between a single channel (e.g., the Physical Downlink Control Channel (PDCCH) or the Physical Downlink Shared Channel (PDSCH)) and the corresponding reference signal (or, more specifically, the demodulation reference signal (DMRS) of the PDSCH or PDCCH and another reference signal (e.g., the source reference signal) (such as the Channel State Information Reference Signal (CSI-RS) or the Synchronization Signal Block (SSB)).
[0051] The UE can receive signaling configuring it to operate according to TCI states (e.g., Radio Resource Control (RRC) signaling), and the UE can communicate with the base station using a beam based on the configured TCI states. For example, different channels or reference signals can be configured with different pools of applicable TCI states (e.g., the PDSCH can have a list of TCI states that may include 8 of 64 possible TCI states, and different channels can utilize different TCI state pools). However, using the corresponding beam indication for each different channel with different TCI states can result in additional processing time and signaling and network overhead. Therefore, a method using TCI states for a common beam indication of multiple uplink or downlink channels or associated reference signals may be desirable.
[0052] As described herein, a UE can be configured with separate beam indications for uplink and downlink beams, for example, using the content of RRC signaling that provides TCI states for both uplink and downlink resources. In such a case, a common TCI state can be used for multiple different channels and reference signals (e.g., uplink or downlink). For example, the UE can receive a message indicating some TCI state information that can be applied to multiple channels and / or reference signals, and the same TCI state configured for the UE can be applied to multiple different channels / reference signals. In some aspects, the base station can send signaling (e.g., RRC signaling) to the UE indicating one or more TCI states, where the TCI states may include a common beam indication for multiple uplink or downlink channels (e.g., multiple channels may share the same RRC-configured TCI state pool). The UE can accordingly receive separate TCI states to be applied to multiple uplink channels or reference signals and multiple downlink channels or reference signals. As an example, a UE may receive a TCI state indicating its applicability to both the Physical Uplink Control Channel (PUCCH) and the Physical Uplink Shared Channel (PUSCH), and another TCI state indicating its applicability to both the PDCCH and PDSCH, respectively. Furthermore, each TCI state applicable to multiple channels, multiple reference signals, or any combination thereof may also include information indicating one or more source reference signals for the UE's QCL assumptions. That is, the TCI state may indicate which source reference signal(s) can be used to derive QCL assumptions associated with multiple channels or reference signals (e.g., QCL assumptions based on Doppler shift, Doppler spread, average delay, delay spread, spatial parameters, or any combination thereof). In some examples, the TCI state information signaled to the UE may include indications of other parameters (e.g., TCI state identifier (ID), power control parameters, timing advance parameters, parameters for codebook-based and / or non-codebook-based transmissions, antenna panel information, etc.). Based on the TCI state, the UE can determine some common beam information and can use the determined beam information to receive or transmit data via the indicated channels. Using TCI status indicators for multiple uplink or downlink channels can result in more efficient signaling for beamforming, as well as reduced network and signaling overhead or reduced latency, and other benefits.

Aspects of this disclosure are further illustrated by apparatus diagrams, system diagrams, and flowcharts relating to beam indication for multiple uplink or downlink channels and reference signals, and are described with reference to these diagrams.

[0057] Base station 105 can communicate with core network 130, communicate with each other, or perform both of these operations. For example, base station 105 can interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) on backhaul links 120 (e.g., via X2, Xn, or other interfaces), or indirectly (e.g., via core network 130), or perform both of these operations. In some examples, backhaul link 120 can be or includes one or more radio links.
[0058] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, node B, evolved node B (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home evolved node B, or some other suitable term.
[0059] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, and other examples. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, and other examples, which may be implemented in various items such as appliances, vehicles, meters, and other examples.
[0060] The UE 115 described in this document can communicate with various types of devices, such as other UE 115s that can sometimes act as repeaters, as well as base station 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, and other examples, such as... Figure 1 As shown.
[0061] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for 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 coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.
[0062] In some examples (e.g., in a carrier aggregation configuration), the carrier may also have acquisition or control signaling that coordinates operation against other carriers. The 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 positioned according to a channel grid for discovery by UE 115. The carrier may operate in standalone mode, where UE 115 performs initial acquisition and connection via the carrier, or the carrier may operate in non-standalone mode, where different carriers (e.g., the same or different radio access technologies) are used to anchor the connection.
[0063] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The carrier may carry downlink or uplink communication (e.g., in FDD mode) or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).
[0064] A carrier can be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth can be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth can be one of a number of defined bandwidths for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) can have a hardware configuration that supports communication on a specific carrier bandwidth, or can be configured to support communication on one carrier bandwidth in a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 can be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.
[0065] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as Orthogonal Frequency Division Multiplexing (OFDM) or Discrete Fourier Transform Spread Spectrum OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements UE 115 receives and the higher the order of the modulation scheme, the higher the data rate can be for UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity used for communication with UE 115.
[0066] One or more digital schemes (numerologies) can be supported for a carrier, where the digital scheme may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier can be divided into one or more BWPs with the same or different digital schemes. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and communication for UE 115 can be restricted to one or more active BWPs.
[0067] It can be expressed in a basic unit of time (which can be, for example, T). s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf maxThis can represent the maximum supported subcarrier spacing, and N f The time interval for base station 105 or UE 115 can be represented as a multiple of the maximum supported Discrete Fourier Transform (DFT) size. The time interval for communication resources can be organized based on radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).
[0068] Each frame may include multiple 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 (e.g., in the time domain) into subframes, 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 symbol periods (e.g., this depends on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N) f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.
[0069] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst form of a shortened TTI (sTTI)).
[0070] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by the number of symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a group of UEs 115. For example, one or more of the UEs 115 can monitor or search for control regions against control information based on one or more search space sets, and each search space set can include one or more control channel candidates arranged in a cascaded manner at one or more aggregation levels. The aggregation level for control channel candidates can 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 set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set used to send control information to a specific UE 115.
[0071] In some examples, base station 105 may be mobile, and therefore provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but 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. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different radio access technologies to provide coverage for various geographic coverage areas 110.
[0072] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timings, and transmissions from different base stations 105 can be approximately time-aligned. For asynchronous operation, base stations 105 can have different frame timings, and in some examples, transmissions from different base stations 105 may not be time-aligned. The techniques described herein can be used for both synchronous and asynchronous operation.
[0073] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can 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 can include service prioritization, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.
[0074] In some examples, UE 115 is able to communicate directly with other UE 115 on a device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, groups of UE 115s communicating via D2D communication can utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.
[0075] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function unit (AMF)) managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function unit (UPF)) routing packets to or interconnecting with external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to IP service 150 for one or more network operators. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.
[0076] Some network devices (e.g., base station 105) may include sub-components such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transport entities 145 (which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP)). 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 individual network devices (e.g., radio headends and ANCs) or incorporated into a single network device (e.g., base station 105).
[0077] Wireless communication system 100 can operate using one or more frequency bands (e.g., in the range of 300 MHz to 300 GHz). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves can be sufficiently penetrating structures to provide service to UE 115 located indoors via macrocells. Compared to the transmission of smaller frequencies and longer waves in the lower frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).
[0078] Wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ licensed assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio frequency spectrum bands, devices (such as base station 105 and UE 115) can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands can be based on carrier aggregation configurations that combine component carriers operating in licensed frequency bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and other examples.
[0079] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operation or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array having a number of rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.
[0080] 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 a technique can be called spatial multiplexing. For example, a transmitting device can transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device can receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) (where multiple spatial layers are transmitted to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are transmitted to multiple devices).
[0081] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to form or guide an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating relative to a specific orientation of the antenna array experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with the transmitting or receiving device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).
[0082] As part of beamforming operations, base station 105 or UE 115 may use beam scanning techniques. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Base station 105 may transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, 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 base station 105) or by a receiving device (such as UE 115)) to identify the beam direction for subsequent transmissions or receptions performed by base station 105.
[0083] Base station 105 may transmit signals (e.g., data signals associated with a specific receiving device, such as UE 115) in a single beam direction (e.g., a direction associated with a particular receiving device, such as UE 115). In some examples, the beam direction associated with transmission 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 that has the highest signal quality or otherwise acceptable signal quality.
[0084] In some examples, multiple beam directions can be used to perform transmissions by a device (e.g., base station 105 or UE 115), and the device can use a combination of digital precoding or radio frequency beamforming to generate combined beams for (e.g., from base station 105 to UE 115) transmissions. UE 115 can report feedback indicating precoding weights for one or more beam directions, and this feedback can correspond to a configured number of beams spanning the system bandwidth or one or more subbands. Base station 105 can transmit reference signals that can be precoded or unprecoded (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)). UE 115 can provide feedback on beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify beam directions for subsequent transmissions or receptions by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).
[0085] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, the receiving device (e.g., UE 115) can attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device can attempt multiple receiving directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or by processing the received signals according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (any of these operations can be referred to as "listening" according to different receiving configurations or receiving directions). In some examples, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). A single receiver configuration can be aligned to a beam direction determined based on listening in different receiver configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening in multiple beam directions).
[0086] Base station 105 may send one or more synchronization signal blocks (SSBs) to UE 115, and UE 115 may process (e.g., decode) the SSBs to obtain system information and initiate communication with the base station. An SSB (e.g., a synchronization block) may include synchronization signals (such as a primary synchronization signal (PSS), a physical broadcast channel (PBCH), and a secondary synchronization signal (SSS)), which may be referred to as an acquisition signal and may be sent from base station 105 to UE 115. The PSS, PBCH, and SSS may each occupy different sets of symbols (e.g., OFDM symbols) and subcarriers of the SSB. UE 115 may utilize the SSBs to obtain downlink synchronization information and system information (e.g., to establish a communication channel with base station 105). In some cases, some wireless communication systems 100 may also utilize SSBs with beam scanning for beam management purposes. In some cases, one or more SSBs may be included within a synchronization signal burst set, which may include a periodic sequence or set of SSBs.
[0087] In some examples, a QCL relationship may exist between one or more transmissions or signals. A QCL relationship between one or more transmissions or signals can refer to the relationship between the antenna ports (and corresponding signaling beams) of the respective transmissions. For example, one or more antenna ports may be implemented by base station 105 for transmitting at least one or more reference signals (such as downlink reference signals, SSBs, etc.) and control information to UE 115. However, the channel characteristics of signals transmitted via different antenna ports can be interpreted (e.g., by the receiving device) as the same (e.g., even though the signals are transmitted from different antenna ports), and the antenna ports (and corresponding beams) can be described as quasi-co-located (QCL). The QCL signal allows UE 115 to deduce the characteristics (e.g., delay spread, Doppler spread, frequency shift, average power) of a first signal transmitted on a first antenna port based on measurements of a second signal transmitted via a second antenna port. In other words, if two antenna ports are classified as QCL according to, for example, delay spread, UE 115 can determine the delay spread for one antenna port (e.g., based on a received reference signal, such as CSI-RS) and then apply the result to both antenna ports. This technique avoids UE 115 having to determine delay spread individually for each antenna port. In some cases, two antenna ports can be considered spatial QCLs, and the characteristics of a signal transmitted on a directional beam can be derived from the characteristics of a different signal on another different directional beam. That is, the QCL relationship can involve beam information of the corresponding directional beams used for communication of various signals.
[0088] Different types of QCL relationships can describe the relationship between two different signals or antenna ports. For example, QCL type A can refer to a QCL relationship between signals that includes Doppler shift, Doppler spread, average delay, and delay spread. QCL type B can refer to a QCL relationship that includes Doppler shift and Doppler spread, while QCL type C can refer to a QCL relationship that includes Doppler shift and average delay. QCL type D can refer to a QCL relationship of spatial parameters, which can indicate the relationship between two or more directional beams used to transmit signals. Here, the spatial parameters indicate that a first beam used to transmit a first signal can be similar to (or identical to) another beam used to transmit a second, different signal, or that the same receiving beam can be used to receive both the first and second signals. Therefore, beam information for various beams can be derived by receiving signals from the transmitting device, where, in some cases, QCL information or spatial information can help the receiving device efficiently identify communication beams (e.g., without having to scan through a large number of beams to identify the optimal beam (e.g., the beam with the highest signal quality)). In addition, QCL relationships can exist between uplink and downlink transmissions, and in some cases, QCL relationships can also be referred to as spatial relationship information.
[0089] In some examples, TCI state configuration may include one or more parameters associated with QCL relationships between transmitted signals. For example, base station 105 may configure QCL relationships that provide a mapping between a reference signal and antenna ports of another signal (e.g., DMRS antenna ports for PDCCH, DMRS antenna ports for PDSCH, CSI-RS antenna ports for CSI-RS, etc.), and base station 105 may indicate the TCI state to UE 115. In some cases, a set of TCI states may be indicated to UE 115 via RRC signaling, where a number of TCI states (e.g., a pool of 8 TCI states from a total of 64 TCI states may be configured via RRC) and a specific TCI state may be indicated via downlink control information (DCI) (e.g., within a CORESET). The QCL relationships associated with TCI states (and further established via higher-layer parameters) may provide UE 115 with the QCL relationships for the corresponding antenna ports and the reference signal transmitted by base station 105.
[0090] Some systems may utilize joint beam indicators (e.g., TCI status indicating certain QCL information), where a common indicator can apply to both uplink and downlink beams. In other cases, separate beam indicators may be used, where a first beam indicator can be used for multiple uplink beams, and a second, different beam indicator can be used for multiple downlink beams. However, for such separate beam indicators, the content of the separate indicator may not be defined.
[0091] In some implementations of the wireless communication system 100, the UE 115 may be configured with beam information (e.g., using TCI states) that indicates resources used for uplink or downlink operation on a beam set. For example, the described techniques may provide separate beam indications for uplink and downlink beams (e.g., RRC signaling providing TCI states for both uplink and downlink resources), where a common TCI state can be used for multiple different channels and reference signals (e.g., for uplink or downlink based on beam indications). The UE may receive messages indicating some TCI state information that can be applied to multiple channels and / or reference signals. That is, the same TCI state indicated to the UE can be applied to multiple different channels / reference signals. Uplink beam indication may include TCI state information that can be applied to multiple uplink channels (e.g., PUCCH and PUSCH) and / or reference signals (e.g., sounding reference signal (SRS), DMRS of PUCCH, DMRS of PUCCH), while downlink beam indication may include TCI state information that can be applied to multiple downlink channels (e.g., PDCCH and PDSCH) and / or reference signals (e.g., SSB, CSI-RS, DMRS of PDSCH, DMRS of PDCCH). In either case, the message may indicate which channels and / or reference signals the TCI state can be applied to. Additionally, the TCI state information may include QCL information indicating various source reference signals used for QCL assumptions.
[0092] In some aspects, a TCI state can be applied to multiple channels and / or reference signals, where the same spatial filter (e.g., the same beam) can be applied to each channel and / or reference signal (e.g., the same beam can be used for all applicable reference signals, and the TCI state can indicate the same source reference signal used for QCL assumptions across multiple reference signals). In other aspects, within the same TCI state, different source reference signals for QCL assumptions can be used for multiple channels and / or reference signals to which the TCI state is to be applied. Here, downlink TCI states can be applied to both PDSCH and PDCCH, and the source reference signal for PDCCH (e.g., for QCL assumptions) can be SSB, while the source reference signal for PDSCH can be CSI-RS. In some examples, different channels can have TCI states selected from the same TCI state pool (e.g., one or more TCI states configured for PDSCH and PDCCH can be selected from the same set of available TCI states).
[0093] The content of a separate beam indication (e.g., TCI status information) may also include an indication of the TCI status ID, which can be indicated using one or more information fields for indicating a common beam, common (e.g., shared) fields for both uplink and downlink beam indications, a separate downlink beam indication, a separate uplink beam indication, or any combination thereof. Additionally, the TCI status information may also indicate details about the source reference signal used for the QCL assumption, uplink power control information, uplink timing advance parameters, parameters for codebook-based transmission, parameters for non-codebook-based transmission, antenna panel ID information, or any combination thereof. In some cases, the technologies supported by the wireless communication system 100 can be used for various communication schemes or deployments (such as carrier aggregation (e.g., in-band carrier aggregation)) and can provide common beam information for data and control transmission and reception between devices.

Therefore, UE 115-a and base station 105-a may share information via communication links 205-a and 205-b. In some examples, wireless communication system 200 may use beamforming techniques such that communication links 205-a and 205-b may include one or more beams.
[0095] Base station 105-a can determine common beam information for uplink and downlink resources and can send message 210 (e.g., RRC signaling) to UE 115-a. Message 210 includes first TCI status information 215-a and second TCI status information 215-b indicating resources for one or more beams. For example, the first TCI status information 215-a may be associated with uplink resources, and the second TCI status information 215-b may be associated with downlink resources. The first TCI status information 215-a and the second TCI status information 215-b may be examples of TCI status information elements and may include indications of one or more TCI states and indications of channels or reference signals to which the corresponding TCI states may be applied. For example, the first TCI status information 215-a may include indications that the TCI states will be applied to multiple uplink channels (e.g., applied to PUCCH and PUSCH) or reference signals, or both. Similarly, the second TCI status information 215-b may include indications that the TCI status will be applied to multiple downlink channels (e.g., PDCCH and PDSCH) or reference signals. It should be noted that the TCI status indicated by the first TCI status information 215-a and the second TCI status information 215-b may also be applied to other channels, and the examples described herein should not be considered limiting. Based on the received message 210, UE 115-a can identify two or more channels or reference signals to which the TCI status can be applied.
[0096] To configure TCI states for multiple channels and / or reference signals, the TCI state information within message 210 (e.g., RRC signaling) may include some indication (e.g., explicit indication) of the channels or reference signals to which the TCI state is applied. In one example, the RRC field may have a bitmap or index, where index values can provide different indications for multiple channels or reference signals associated with the TCI state. For example, each index value may indicate beam information (e.g., TCI state) that can be applied to one or more channels, where bit value 0 (e.g., 3-bit binary 000) may indicate beam information that can be applied to the PDSCH, bit value 1 (e.g., 001) may indicate beam information that can be applied to both the PDSCH and PDCCH, bit value 2 (e.g., 010) may indicate beam information that can be applied to a channel, a reference signal, or some other combination of both, and so on. Alternatively, a bitmap may provide an indication of the channels to which the beam information can be applied, where the first bit in the bitmap may indicate the PDSCH, the second bit in the bitmap may indicate the PDSCH, and three bits in the bitmap may indicate the SRS. In such a case, the value (e.g., 0 or 1) in the bitmap corresponding to each channel or reference signal can indicate whether beam information can be applied to that channel or reference signal; otherwise, beam indication may not be applied to that channel or reference signal. Therefore, different values in the bitmap can indicate to the UE 115-a a combination of multiple channels and / or reference signals to which TCI states can be applied.
[0097] TCI state information 215 (e.g., one or both of first TCI state information 215-a or second TCI state information 215-b) may indicate the applicable channels and / or reference signals for a TCI state (e.g., uplink TCI state or downlink TCI state), and the TCI state may also indicate beam information or spatial filter information that can be applied to multiple channels and / or reference signals. In one aspect, the same beam may be used for each of multiple channels, or each of multiple reference signals, or any combination thereof, such that UE 115-a may use the same beam configuration or spatial filter to transmit or receive on each channel indicated by the TCI state information 215. In such a case, the TCI state may be associated with the same or common source reference signal (e.g., CSI-RS, SSB, etc.) used for QCL assumptions. In other words, the same source reference signal associated with a TCI state shared by multiple channels / reference signals may indicate the same beam used for multiple channels / reference signals.
[0098] Alternatively, the TCI state may indicate a different beam, spatial filter, or source reference signal, for example, for each channel or reference signal to which the TCI state applies. For example, the TCI state indicated by the second TCI state information 215-b may apply to both the PDCCH and PDSCH, but may include indications of different source reference signals for the QCL assumptions associated with each channel. In such a case, the PDCCH may use the SSB as the source reference signal for the QCL assumptions, and the PDSCH may use the CSI-RS as the source reference signal for the QCL assumptions. In some examples, the SSB may correspond to a relatively wide beam, and the CSI-RS may correspond to a relatively narrow beam (e.g., compared to the SSB beam), and UE115-a may therefore identify these corresponding beams as corresponding to different channels (e.g., based on the TCI state indicated by the TCI state information).
[0099] TCI status information 215 (e.g., one or both of first TCI status information 215-a or second TCI status information 215-b) may include an indication (e.g., within one or more information fields or information elements) of an identifier (ID) associated with the configured TCI status. In some implementations, the TCI status ID may be indicated via a dedicated ID space for common beam indication (or indication of multiple common beams), or in a common ID space shared for common uplink and / or downlink beam indication. In other examples, the TCI status ID may be indicated in a field for downlink beam indication or a field for uplink beam indication (e.g., where the downlink TCI status and uplink TCI status indicating beam information may be in corresponding information fields). In some cases, the first TCI status information 215-a and the second TCI status information 215-b of a message (e.g., RRC signaling) may indicate, for example, which two channels or reference signals the TCI status (identified via the TCI status ID) can be applied to. Then, base station 105-a can send DCI to UE 115-a and can select the TCI state via indications provided by the DCI (e.g., within one or more fields). Therefore, UE 115-a can know which channels the TCI state should apply to (according to RRC signaling). Here, multiple channels and / or reference signals indicated by the TCI state information can share the same or common TCI state pool. In one example, both PUSCH and PUSCH can share the same TCI state pool. In one example, the TCI state ID corresponding to one or more TCI state pools can be indicated in the configuration provided by TCI state information 215. Different values can exist for different TCI states, which can be applied to different beam indication schemes. For example, a TCI state that may apply only to one channel or reference signal (e.g., a conventional set of TCI states) may correspond to a first set of TCI states (e.g., a first set of 64 TCI states with IDs from index 0 to 64), while a TCI state that may apply to multiple channels or reference signals (as described herein) may correspond to a second set of TCI states (e.g., a second set of 64 TCI states with IDs from index 65 to 128).
[0100] The first TCI state information 215-a and the second TCI state information may include various information related to the source reference signal used for QCL assumptions. Therefore, UE 115-a can use the QCL information provided within the TCI state information to determine the source reference signal providing various QCL assumptions. Thus, UE 115-a can measure the source reference signal (e.g., CSI-RS or SSB) that can be associated with a given TCI state. Then, based on the measurement of the source reference signal and the applicable TCI state, UE 115-a can know how to transmit or receive multiple channels or reference signals associated with the source reference signal. Therefore, each TCI state information 215 may have a source reference signal information field, which can indicate one or more source reference signals that can be used for QCL assumptions. Specifically, for each QCL information (e.g., a QCLInfo information element) within the TCI state information 215, one or more source reference signals can provide various QCL assumptions, including characteristics of delay parameters, Doppler parameters, spatial reception parameters, spatial transmission parameters, or any combination thereof.
[0101] The source reference signal providing the QCL assumption can have one of several types (e.g., SSB, CSI-RS, SRS, Position Reference Signal (PRS), Physical Random Access Channel (PRACH), or DMRS associated with PDSCH, DMRS associated with PDCCH, DMRS associated with PUCCH, or DMRS associated with PUSCH, or any combination thereof). Additionally, each source reference signal can provide at least one type of QCL assumption. For example, the source reference signal for downlink reception can have associated types indicating one or more QCL characteristics (e.g., QCL-Type A, QCL-Type B, QCL-Type C, QCL-Type D). A QCL-Type A source reference signal can indicate Doppler shift, Doppler spread, average delay, and delay spread parameters. A QCL-Type B source reference signal indicates Doppler shift and Doppler spread. A QCL-Type C source reference signal can indicate Doppler shift and average delay. A QCL-Type D source reference signal can indicate spatial reception parameters. Similarly, the uplink source reference signal can provide spatial relational information for spatial transmission parameters, as well as a description of the QCL characteristics associated with uplink QCL-Type A / B / C (e.g., QCL-Type A, QCL-Type B, or QCL-Type C). In some examples, each source reference signal can provide multiple QCL assumptions. For instance, the SSB as a source reference signal can provide both QCL-Type D and uplink spatial relational information for a common beam.
[0102] TCI status information 215 may include location information for the source reference signal. For example, each source reference signal may have or include location information associated with the location of the source reference signal, wherein the location information may include the serving cell ID, BWP ID, or both of which the source reference signal resides in (e.g., in the frequency domain). In some examples, if the serving cell ID is not included in the location information, UE 115-a may assume that the source reference signal is applied to a serving cell on which the corresponding TCI status is configured. In some examples, the serving cell associated with the source reference signal may be different from the serving cell on which the TCI status is configured, for example, if the reference signal is configured for some QCL type (e.g., QCL-Type C or QCL-Type D). Alternatively, if the BWP ID is not included in the location information, UE 115-a may assume that the reference signal is applied to an active BWP (e.g., an active uplink BWP or an active downlink BWP).
[0103] In some examples, TCI state information 215 may indicate a combination of source reference signals to indicate uplink or downlink beamforming based on the provided QCL and / or spatial assumptions. In one example, the TCI state may indicate one source reference signal for providing QCL-Type A / B / C assumptions (e.g., QCL-Type A, QCL-Type B, or QCL-Type C). In another example, the TCI state may indicate three source reference signals, including one for providing QCL-Type A / B / C assumptions, another for providing QCL-Type D assumptions, and another for providing spatial relational information. In some other examples, the TCI state may indicate two source references, including one for providing QCL-Type A / B / C assumptions and another for providing both QCL-Type D assumptions and spatial relational information. In another example, the TCI state may indicate three source reference signals, including one source reference signal for providing the QCL-Type A / B / C assumption, another source reference signal for providing both the QCL-Type D assumption and spatial relation information, and yet another source reference signal for providing the uplink QCL-Type A / B / C assumption. In some examples, if the TCI state indicates multiple uplink or downlink beams for multiple channels or reference signals, each uplink or downlink beam channel or reference signal may be indicated by a different set of source reference signals for the QCL or spatial assumptions.
[0104] In some examples, TCI status information 215 (e.g., one or both of first TCI status information 215-a or second TCI status information 215-b) may include (e.g., in one or more information fields or information elements) indications of uplink power control parameters (e.g., path loss reference signal, target received power parameter (e.g., P0), path loss compensation factor (which may be referred to as alpha), closed-loop power control index, power control group ID, etc.). In some examples, the TCI status may indicate multiple uplink beams, or the TCI status may be applied to multiple channels or reference signals, and each uplink beam, reference signal, or channel may have a different set of associated uplink power control parameters than other common uplink or downlink beams. That is, appropriate power control parameters can be configured for different beams, channels, reference signals, or any combination thereof associated with the TCI status.
[0105] TCI status information 215 (e.g., one or both of first TCI status information 215-a or second TCI status information 215-b) may additionally or alternatively include (e.g., in one or more information fields or information elements) an indication of uplink timing advance parameters. For example, the TCI status information may include a timing advance group ID or timing advance value for uplink transmission of the uplink beam. In some examples, if the TCI status indicates multiple uplink beams or can be applied to multiple reference signals or channels, each beam, channel, or reference signal may have an associated set of uplink timing advance parameters, which may be the same as or different from other common uplink or downlink beams.
[0106] In some examples, TCI status information 215 (e.g., one or both of first TCI status information 215-a or second TCI status information 215-b) may include (e.g., in one or more information fields or information elements) indications of parameters, or both, for codebook-based transmissions (e.g., transmissions on PUSCH) or non-codebook-based transmissions. For example, TCI status information may include a Schedule Request Indicator (SRI), a Transmit Precoding Matrix Indicator (TPMI), a Transmission Request Indicator (TRI), or any combination thereof for PUSCH transmissions on uplink beams. In some examples, if the TCI status indicates multiple uplink beams, each beam may have a set of parameters for codebook-based or non-codebook-based PUSCH transmissions. In such cases, the corresponding transmission parameters may be associated with different beams, channels, or reference signals.
[0107] In some examples, TCI status information 215 (e.g., one or both of first TCI status information 215-a or second TCI status information 215-b) may include (e.g., in one or more information fields or information elements) an indication of one or more UE panel IDs or similar IDs. For example, UE 115 may have an antenna panel defined as having, for example, independent analog beams, uplink power control, uplink timing advance, etc. Therefore, the TCI status information may include the UE panel ID to which the configured TCI status applies (also referred to as, for example, antenna port group ID, beam group ID, etc.). In some examples, the TCI status information may include a different UE panel ID for each uplink channel to which the TCI status applies. In other examples, the TCI status information may include a single UE panel ID applicable to all uplink channels to which the TCI status applies. In some examples, if the TCI status information indicates multiple uplink beams or applies to multiple channels or reference signals, each beam, channel, or reference signal may have a different UE panel ID or may share the same panel ID.
[0108] Implementing various aspects of the wireless communication system 200 can result in reduced network and signaling overhead. For example, the TCI state ID space can have a reduced size because TCI state information 215 (e.g., indicating one or more TCI states) can be applied to multiple beams, channels, or reference signals. Similarly, TCI states for multiple channels or reference signals can be established, updated, or applied via fewer control signal transmissions (e.g., one control signal transmission for all channels or reference signals, rather than one control signal transmission for each channel or reference signal). For example, if a TCI state applies to both PDSCH and PDCCH, then if a TCI state is selected for PDSCH, it can also be selected for PDCCH CORESET (e.g., automatically or implicitly). Note that this can be applied to TCI states applicable to PUCCH, SRS, PUSCH, or any combination thereof.
[0109] Figure 3 Examples of process flow 300 in a system supporting beam indication for multiple uplink or downlink channels and reference signals, according to one or more aspects of this disclosure, are shown. In some examples, process flow 300 can implement as referenced... Figure 1 and 2The wireless communication system 100 or 200 described herein includes various aspects. Process flow 300 may include UE 115-b and base station 105-b, which may be examples of the corresponding devices described herein. Alternative examples are possible, some of which may be executed in a different order than described or not at all. In some examples, processes may include additional features not mentioned below, or additional processes may be added.
[0110] At 305, base station 105a can determine common beam information for uplink or downlink resources. For example, base station 105a can identify one or more sets of resources associated with beams used for uplink or downlink transmission.
[0111] At 310, base station 105-a can be configured with a TCI state for a channel or reference signal. For example, base station 105-a can be configured with a TCI state for multiple uplink or downlink channels or reference signals (e.g., PUCCH, PUSCH, PDCCH, PDSCH, SRS, CSI-RS, etc.), allowing TCI states for multiple channels or reference signals to be configured, updated, or applied simultaneously.
[0112] At point 315, base station 105-b can send, and UE 115-b can receive, signaling indicating the TCI status (e.g., RRC signaling). Specifically, this signaling may include separate beam indications for uplink and downlink resources (e.g., TCI status information, which may be examples of information elements or other information fields). As an example, base station 105-b can send a message including first TCI status information and second TCI status information, wherein the first TCI status information may differ from the second TCI status information. In such a case, the first TCI status information may be associated with multiple uplink resources (e.g., time / frequency resources and / or corresponding directional beams), and the second TCI status information may be associated with multiple downlink resources.
[0113] At 320, UE 115-b can determine which channels or reference signals to apply the TCI state to based on indications included in the TCI state information. For example, the TCI state information may include indications of the channels or reference signals to which the TCI state applies, along with related information as described herein. In such a case, UE 115-b can identify multiple (e.g., two or more) channels, reference signals, or any combination thereof to which the TCI state is to be applied. Multiple channels may include uplink channels indicated in the first TCI state information or downlink channels indicated in the second TCI state information. Additionally, the TCI state applied to multiple channels and / or reference signals may correspond to one or more source reference signals associated with a QCL assumption for two or more channels, or reference signals, or any combination thereof. That is, the TCI state information may also indicate which source reference signals (such as one or more SSBs, one or more CSI-RS, etc.) can be used for the QCL assumption of multiple channels and / or reference signals.
[0114] At 325, UE 115-b can determine common beam information based on the TCI state and the channel or reference signal to which the TCI state applies. For example, UE 115-b can determine resources for uplink or downlink beams based on the TCI state. At 330, UE 115-b can communicate with base station 105-b based on the determined resources. For example, UE 115-b can transmit or receive information on multiple channels and using one or more beams determined based on the TCI state.
[0115] Figure 4 A block diagram 400 illustrates a device 405 supporting beam indication for multiple uplink or downlink channels and reference signals according to various aspects of this disclosure. Device 405 may be an example of various aspects of UE 115 as described herein. Device 405 may include a receiver 410, a transmitter 415, and a communications manager 420. Device 405 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).
[0116] Receiver 410 may provide a unit for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels associated with beam indication for multiple uplink or downlink channels and reference signals). The information may be passed to other components of device 405. Receiver 410 may utilize a single antenna or a collection of multiple antennas.
[0117] Transmitter 415 may provide a unit for transmitting signals generated by other components of device 405. For example, transmitter 415 may transmit information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels associated with beam indication for multiple uplink or downlink channels and reference signals). In some examples, transmitter 415 may be co-located with receiver 410 in a transceiver module. Transmitter 415 may utilize a single antenna or a collection of multiple antennas.
[0118] Communication manager 420, receiver 410, transmitter 415, or various combinations thereof, or various components thereof, may be examples of units for performing various aspects of beam indication for multiple uplink or downlink channels and reference signals described herein. For example, communication manager 420, receiver 410, transmitter 415, or various combinations thereof, or components thereof, may support methods for performing one or more of the functions described herein.
[0119] In some examples, the communication manager 420, receiver 410, transmitter 415, or various combinations or components thereof may be implemented in hardware (e.g., in communication management circuitry). The hardware may include a processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination thereof configured to or otherwise support units for performing the functions described herein. In some examples, a processor and memory coupled to a processor may be configured to perform one or more of the functions described herein (e.g., by executing instructions stored in memory by the processor).
[0120] Alternatively or concurrently, in some examples, the communication manager 420, receiver 410, transmitter 415, or various combinations or components thereof may be implemented using code executed by a processor (e.g., as communication management software or firmware). If implemented using processor-executed code, the functionality of the communication manager 420, receiver 410, transmitter 415, or various combinations or components thereof may be performed by a general-purpose processor, DSP, central processing unit (CPU), ASIC, FPGA, or any combination of these or other programmable logic devices (e.g., a unit configured or otherwise supported for performing the functions described in this disclosure).
[0121] In some examples, the communication manager 420 may be configured to use or otherwise cooperate with the receiver 410, transmitter 415, or both to perform various operations (e.g., receiving, monitoring, transmitting). For example, the communication manager 420 may receive information from the receiver 410, send information to the transmitter 415, or integrate with the receiver 410, transmitter 415, or both to receive information, send information, or perform various other operations as described herein.
[0122] According to the examples disclosed herein, the communication manager 420 may support wireless communication at the UE. For example, the communication manager 420 may be configured or otherwise supported to receive a message comprising first transmission configuration indicator status information and second transmission configuration indicator status information different from the first transmission configuration indicator status information, wherein the first transmission configuration indicator status information is associated with a set of multiple uplink resources, and wherein the second transmission configuration indicator status information is associated with a set of multiple downlink resources. The communication manager 420 may be configured or otherwise supported to identify two or more channels, or reference signals, or any combination thereof to which transmission configuration indicator status is to be applied, the two or more channels including two or more uplink channels indicated in the first transmission configuration indicator status information or two or more downlink channels indicated in the second transmission configuration indicator status information, wherein the transmission configuration indicator status corresponds to one or more source reference signals associated with a QCL assumption for the two or more channels, or reference signals, or any combination thereof. The communication manager 420 can be configured or otherwise supported to determine common beam information for a set of uplink resources or a set of downlink resources based on applying transmission configuration indicator states to two or more channels, or reference signals, or any combination thereof.
[0123] By including or configuring the communication manager 420 according to the examples described herein, the device 405 (e.g., a processor that controls or otherwise couples to the receiver 410, transmitter 415, communication manager 420, or a combination thereof) can support techniques for reducing processing, reducing network or signaling overhead, reducing latency, or more efficient communication, as well as other benefits.
[0124] Figure 5A block diagram 500 of a device 505 supporting beam indication for multiple uplink or downlink channels and reference signals, according to various aspects of this disclosure, is shown. Device 505 may be an example of aspects of device 405 or UE 115 as described herein. Device 505 may include a receiver 510, a transmitter 515, and a communication manager 520. Device 505 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).
[0125] Receiver 510 may provide a unit for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels associated with beam indication for multiple uplink or downlink channels and reference signals). The information may be passed to other components of device 505. Receiver 510 may utilize a single antenna or a collection of multiple antennas.
[0126] Transmitter 515 may provide a unit for transmitting signals generated by other components of device 505. For example, transmitter 515 may transmit information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels associated with beam indication for multiple uplink or downlink channels and reference signals). In some examples, transmitter 515 may be co-located with receiver 510 in a transceiver module. Transmitter 515 may utilize a single antenna or a collection of multiple antennas.
[0127] Device 505 or its various components may be examples of units for performing various aspects of beam indication for multiple uplink or downlink channels and reference signals as described herein. For example, communication manager 520 may include beam indication manager 525, TCI status manager 530, beam manager 535, or any combination thereof. Communication manager 520 may be examples of various aspects of communication manager 420 as described herein. In some examples, communication manager 520 or its various components may be configured to use receiver 510, transmitter 515, or both, or otherwise cooperate with receiver 510, transmitter 515, or both to perform various operations (e.g., receiving, monitoring, transmitting). For example, communication manager 520 may receive information from receiver 510, send information to transmitter 515, or be integrated with receiver 510, transmitter 515, or both to receive information, send information, or perform various other operations as described herein.
[0128] According to the examples disclosed herein, the communication manager 520 may support wireless communication at the UE. The beam indicator manager 525 may be configured or otherwise supported to receive a message including first TCI state information and second TCI state information different from the first TCI state information, wherein the first TCI state information is associated with a set of multiple uplink resources, and wherein the second TCI state information is associated with a set of multiple downlink resources. The TCI state manager 530 may be configured or otherwise supported to identify two or more channels, or reference signals, or any combination thereof to which a TCI state is to be applied. In some examples, the two or more channels may include two or more uplink channels indicated within the first TCI state information or two or more downlink channels indicated within the second TCI state information. In some examples, the TCI state may correspond to one or more source reference signals associated with a QCL assumption for two or more channels, or reference signals, or any combination thereof. The beam manager 535 can be configured or otherwise supported as a unit for determining common beam information for a set of uplink resources or a set of downlink resources based on applying TCI states to two or more channels, or reference signals, or any combination thereof.
[0129] Figure 6 A block diagram 600 is shown of a communication manager 620 supporting beam indication for multiple uplink or downlink channels and reference signals according to various aspects of this disclosure. The communication manager 620 may be an example of aspects of the communication manager 420, communication manager 520, or both as described herein. The communication manager 620 or its various components may be examples of units for performing various aspects of beam indication for multiple uplink or downlink channels and reference signals as described herein. For example, the communication manager 620 may include a beam indication manager 625, a TCI status manager 630, a beam manager 635, a source reference signal manager 640, a beam assembly 645, a TCI status ID manager 650, a hypothesis manager 655, a position manager 660, a power control manager 665, a timing manager 670, a codebook manager 675, a panel ID manager 680, a QCL type manager 685, or any combination thereof. Each of these components may communicate directly or indirectly with each other (e.g., via one or more buses).
[0130] According to the examples disclosed herein, the communication manager 620 may support wireless communication at the UE. The beam indication manager 625 may be configured or otherwise supported to receive a message including first TCI state information and second TCI state information different from the first TCI state information, wherein the first TCI state information is associated with a set of multiple uplink resources, and wherein the second TCI state information is associated with a set of multiple downlink resources. The TCI state manager 630 may be configured or otherwise supported to identify two or more channels, or reference signals, or any combination thereof to which a TCI state is to be applied. In some examples, the two or more channels may include two or more uplink channels indicated in the first TCI state information or two or more downlink channels indicated in the second TCI state information. In some examples, the TCI state may correspond to one or more source reference signals associated with a QCL assumption for two or more channels, or reference signals, or any combination thereof.
