Technical Field
[0003] In summary, this disclosure relates to electronic devices. More specifically, this disclosure relates to non-serving cell states. Background Technology
[0004] Over the past few decades, the use of electronic devices has expanded. In particular, advancements in electronic technology have reduced the cost of increasingly complex and useful electronic devices. Lower costs and consumer demand have led to a surge in the use of electronic devices, making them virtually ubiquitous in modern society. As the use of electronic devices has expanded, so too has the demand for new functions and improved features. More specifically, electronic devices that perform new functions and / or perform functions faster, more efficiently, or with higher quality are often highly sought after.
[0005] Some electronic devices (e.g., cellular phones, smartphones, laptops, etc.) communicate with other electronic devices. For example, electronic devices can send and / or receive radio frequency (RF) signals to communicate. Attached Figure Description

[0016] Some examples of the systems and methods disclosed herein relate to non-serving cell states. For example, some techniques described herein can provide one or more Transport Configuration Indicator (TCI) states associated with one or more non-serving cells. Some techniques described herein can provide rules for one or more TCI states associated with one or more non-serving cells (e.g., non-serving cell reference signals (RS)).
[0017] Associating TCI states with non-serving cells (e.g., reference signals for non-serving cells) enables the use of Layer 1 (L1) measurements and reporting for non-serving cells, in addition to their use with serving cells. Associating TCI states with non-serving cells also enables rapid handover of data or control channels to the TCI states of other (e.g., non-serving) cells. Finally, by associating the aperiodic Channel State Information Reference Signal (AP-CSI-RS) or Tracking Reference Signal (TRS) with the TCI of (multiple) other cells, associating TCI states with non-serving cells enables enhanced measurements of beams in other (e.g., non-serving) cells.
[0018] A wireless communication device is an electronic device that can communicate with one or more other devices using radio frequency (RF) signals. Examples of wireless communication devices include smartphones, tablets, laptops, mobile devices, vehicles, autonomous vehicles, user equipment (UE), telematics units, embedded devices, etc. A base station is an electronic device that can communicate with one or more wireless communication devices. In some examples, a base station can provide wireless communication devices with access to a network (e.g., a cellular network, a local area network (LAN), a wide area network (WAN), the Internet, etc.). In some examples, wireless communication devices (e.g., UE, embedded devices, telematics units, mobile devices, etc.) and / or base stations (e.g., Node B, evolved Node B (eNB), g Node B (gNB), etc.) can perform and / or utilize various radio technologies, such as Global System for Mobile Communications (GSM), third-generation radio (3G) (e.g., Universal Mobile Telecommunications System (UMTS), Code Division Multiple Access 2000 (CDMA2000), Wideband Code Division Multiple Access (WCDMA), etc.), fourth-generation radio (4G) (e.g., Long Term Evolution (LTE), etc.) and / or fifth-generation radio (5G) (e.g., New Radio (NR), etc.).
[0019] As used herein, a cell can refer to a wireless communication resource. For example, a cell can refer to a geographical area in which one or more time, frequency, and / or spatial resources can be utilized for wireless communication. A base station can correspond to and / or provide one or more cells. A serving cell can be a cell used to transmit payload data (e.g., uplink and / or downlink data) with a wireless communication device. In some examples, a serving cell can be a cell in a connected mode (e.g., RRC_connected mode) or an idle mode (e.g., RRC_idle) with a wireless communication device. For example, a wireless communication device can monitor one or more channels of the serving cell (e.g., Physical Downlink Control Channel (PDCCH) and / or Physical Downlink Shared Channel (PDSCH)) for payload data. A non-serving cell can be a cell not configured to transmit payload data with a wireless communication device. In some examples, a wireless communication device (e.g., a UE) can be configured to have a list of one or more non-serving cells to monitor. For example, when a wireless communication device moves out of the coverage of the current serving cell, one or more non-serving cells can be candidates to become the next serving cell(s).
[0020] Some of the configurations described herein can implement Layer 1 (L1) and / or Layer 2 (L2) inter-cell mobility. For example, inter-cell mobility can refer to the ability of a wireless communication device to move between cells. For instance, a wireless communication device can move between cells where cell service can be switched or hand-off between cells. As used herein, the term "layer" and its variations can refer to one or more protocol layers in some examples. For example, L1 can refer to the Physical (PHY) layer of the protocol stack, L2 can refer to the Media Access Control (MAC) layer of the protocol stack, and / or Layer 3 (L3) can refer to the Radio Resource Control (RRC) layer of the protocol stack. In some examples, one or more other layers can be included in L1, L2, and / or L3. For example, L2 can include the Radio Link Control (RLC) protocol, the Packet Data Convergence Protocol (PDCP), and / or the MAC protocol.
[0021] In some approaches, inter-cell mobility is handled at L3 (e.g., the RRC layer). Implementing inter-cell mobility at L1 and / or L2 can improve inter-cell mobility performance. For example, handling inter-cell mobility at L1 and / or L2 can enable faster handover (e.g., with less latency and / or delay).
[0022] TCI status can be a set of information that can be used to perform communication with one or more cells. In some examples, TCI status may include reference signal (RS) information (e.g., reference signal measurement results, reference signal indicators, etc.). Reference signals can be signals transmitted from a base station. Examples of reference signals may include Channel State Information Reference Signal (CSI-RS), Tracking Reference Signal (TRS), and / or Synchronization Signal Block (SSB), etc. In some examples, reference signals can be used to determine one or more parameters used for communication. For example, reference signals can be used to determine RSS, Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), and / or Rank Indicator (RI) used for reporting to the base station. RSS, CQI, PMI, and / or RI can be used to determine one or more aspects of the communication link (e.g., transmit power, precoding, and / or the number of antennas used, etc.).
[0023] In some approaches, a TCI state may be associated with only one or more serving cell beams and / or serving cell reference signals. In some examples of the techniques described herein, one or more non-serving cell reference signals may be associated with one or more TCI states used for measurement and / or reporting of one or more non-serving cells. One or more benefits may be achieved by associating TCI states with one or more non-serving cell reference signals. In some examples, associating TCI states with one or more non-serving cell reference signals can enable L1-based measurement results and / or reporting for non-serving cells. In some examples, associating TCI states with one or more non-serving cell reference signals can enable one or more control channels supporting handover data (e.g., fast handover data) and / or for one or more non-serving cells (e.g., one or more other cell beams) in one or more TCI states. In some examples, enhanced measurement of one or more non-serving cell beams may be supported by associating one or more reference signals (e.g., aperiodic CSI-RS (AP-CSI-RS), TRS, etc.) with one or more TCI states.
[0024] In some examples, the TCI state can be configured to support association with one or more non-serving cell reference signals. For example, the TCI state content can be modified to include information for one or more non-serving cell reference signals. In some examples, the procedures for activating and / or updating one or more TCI states associated with one or more non-serving cell reference signals can be modified. For example, multiple application times can be established for activating and / or updating multiple TCI states of multiple non-serving cell reference signals.
[0025] Various configurations will now be described with reference to the accompanying drawings, wherein similar reference numerals may or may not indicate functionally similar elements. The systems and methods generally described and illustrated in the drawings herein can be arranged and designed in a wide variety of different configurations. Therefore, the following more detailed description of several configurations, as illustrated in the drawings, is not intended to limit the scope of the claims, but merely to represent systems and methods.
[0026] Introduction to wireless communication networks
[0027] Figure 1 This is a schematic diagram of an example of a wireless communication device 102 in which one or more non-serving cell states can be utilized. The wireless communication device 102 may be related to... Figure 2 An example of the described wireless communication device 202. Figure 1The diagram also shows a first base station 112. The first base station 112 may be a radio access network (RAN), or may be included within a RAN. In some examples, the first base station 112 may be related to... Figure 2 An example of base station 226 is described. A second base station 128 is also shown. In this example, wireless communication device 102 communicates with first base station 112. For example, first base station 112 transmits one or more signals to wireless communication device 102 on first channel 122. In some examples, first base station 112 may serve a cell. For example, wireless communication device 102 may transmit payload data with first base station 112 (e.g., transmit payload data to and / or receive payload data from first base station 112). In some examples, wireless communication device 102 may be in a connection mode with first base station 112.
[0028] In some examples, the first base station 112 may send a message to the wireless communication device 102 indicating a TCI state. For example, the first base station 112 may send a message to the wireless communication device 102 to configure one or more TCI states. In some approaches, the message may be a TCI State Information Element (IE). In some examples, the message may include and / or indicate a non-serving cell identifier. The non-serving cell identifier may be information that identifies a non-serving cell and / or implements the identification of the non-serving cell. In some examples, the first base station 112 may send a reference signal (e.g., a serving cell reference signal).
[0029] In some examples, the second base station 128 may transmit one or more reference signals to the wireless communication device 102. For example, the second base station 128 may transmit one or more non-serving cell reference signals to the wireless communication device 102 via the second channel 124.
[0030] In some examples, wireless communication device 102 may determine the TCI state based on the message and a reference signal received from a second base station 128 (e.g., a non-serving cell). Wireless communication device 102 may utilize the received reference signal to determine one or more values of the TCI state. For example, wireless communication device 102 may set one or more values of the TCI state based on a reference signal received from a non-serving cell. Examples of one or more values of the TCI state may include CSI-RS values (e.g., non-zero power CSI-RS (NZP-CSI-RS-ResourceId)), SSB values (e.g., SSB-Index), etc. In some cases, the TCI state may be used for reporting and / or handover. For example, wireless communication device 102 may report one or more parameters (e.g., RSS, CQI, PMI, RI, etc.) to a first base station 112 based on a non-serving cell reference signal and / or may handover to the second base station 128, which may switch to serving the wireless communication device 102.

In some examples, multiple antennas 204 can be used to receive one or more signals (e.g., multiple messages indicating multiple TCI states, configuration signals, etc.) from another device (e.g., base station 226). For example, multiple antennas 204 can provide the received signals to transceiver 206 of wireless communication device 202.
[0034] Processor 210 may be hardware (e.g., circuitry, transistors, etc.) for performing one or more operations. In some examples, processor 210 may be one or more modems (e.g., modem processors) for performing operations (e.g., modulation, encoding, precoding, formatting, demodulation, decoding, etc.). For example, processor 210 may perform one or more operations on one or more signals and provide signals(s) to transceiver 206 for transmission. In some examples, processor 210 may control one or more aspects of the operation of transceiver 206. For example, processor 210 may control antenna port switching, antenna weighting (e.g., phase weighting and / or gain weighting), etc., to enable transmission and / or reception on one or more carrier, beam, streaming, and / or multiple-input multiple-output (MIMO) layers. In some examples, processor 210 may perform one or more operations on signals received from a receiver. For example, processor 210 may perform demodulation, detection, decoding, etc., and / or convert signals(s) or portions of signals(s) into data (e.g., bits).
[0035] In some examples, processor 210 executes instructions to perform one or more functions.

For example, base station processor 220 may perform one or more operations on one or more signals and provide signals(s) to base transceiver 216 for transmission. In some examples, base station processor 220 may control one or more aspects of the operation of base transceiver 216.

For example, base station processor 220 may perform demodulation, detection, decoding, etc., and / or convert signals(s) or portions of signals(s) into data (e.g., bits).
[0040] In some examples, base station processor 220 executes instructions to perform one or more functions. In some examples, base station processor 220 includes one or more functions structurally implemented as hardware (e.g., circuitry). In some examples, base station processor 220 includes a baseband processor, a modem processor, an application processor, and / or any combination thereof.

In some examples, base station 226 and / or base station processor 220 includes one or more components and / or elements described with respect to one or more of the accompanying drawings.
[0041] In some examples, wireless communication device 202, processor 210, transceiver 206, base station 226, base station processor 220, and / or base station transceiver 216 may implement one or more aspects of one or more specifications (e.g., 3GPP Release 25, 3GPP Release 26, 5G, New Radio (NR), and / or Long Term Evolution (LTE), etc.). In some examples, wireless communication device 202 transmits signals to and / or receives signals from one or more base stations (e.g., base station 226). For example, wireless communication device 202 may transmit signals to and / or receive signals from one or more RANs, eNBs, gNBs, cellular networks, etc. In some examples, wireless communication device 202 also communicates with one or more radio access technologies (RATs) (e.g., cellular networks, wireless local area networks (WLANs), Wi-Fi networks, personal area networks (PANs), and / or Bluetooth, etc.).
[0042] In some examples, base station 226 (e.g., base station processor 220 and / or base station TCI state configuration controller 218) can be configured to determine configurations for one or more TCI states. For example, base station 226 may determine one or more cells (e.g., serving cells and / or non-serving cells) monitored by wireless communication device 202, one or more non-serving cell identifiers, one or more resources (e.g., time and / or frequency resources for non-serving cell monitoring, such as bandwidth portions (BWP)), and one or more quasi-co-location (QCL) types (e.g., type A, type B, type C, type D, etc.) corresponding to the one or more non-serving cells. The QCL type may indicate the relationship between the TCI state and a reference signal. For example, QCL type A may indicate a sharing factor (e.g., Doppler shift, Doppler spread, delay, and / or delay spread) between the reference signal and the TCI state. Other QCL types can indicate fewer sharing factors (e.g., type B can indicate shared Doppler shift and Doppler spread, type C can indicate shared delay and Doppler shift, and / or type D can indicate shared reception angle and / or spatial filter). For example, QCL types can indicate the relationship between the reference signal in the non-serving cell and the associated TCI state.
[0043] In some examples, base station 226 may determine the configuration for the TCI state based on one or more communications with one or more base stations (e.g., nearby base stations, neighboring base stations, etc.) and / or data about one or more base stations (e.g., (multiple) nearby base stations, (multiple) neighboring base stations, etc.). For example, base station 226 may communicate with one or more other base stations ( Figure 2The base station 226 communicates with (not shown) other base stations to determine resources (e.g., time and / or frequency resources, BWP, etc.) on which (multiple) other base stations transmit reference signals. In some examples, base station 226 may communicate with (multiple) base stations using one or more wired and / or wireless links (e.g., (multiple) backhaul links). In some ways, base station 226 may communicate with one or more other base stations to determine one or more non-serving cell identifiers for monitoring. In some examples, the information used to determine the configuration for the TCI state may be previously stored and / or based on input received from the user.
[0044] In some examples, base station 226 may include a transmitter configured to send a message indicating a TCI state. For example, base station 226 may send a message to wireless communication device 202 indicating a determined configuration for the TCI state. This message may be used (by, for example, wireless communication device 202) to determine the TCI state based on one or more non-serving cell identifiers and one or more reference signals from one or more non-serving cells. In some examples, base station 226 may serve a cell for wireless communication device 202 and / or serve wireless communication device 202 and / or one or more other wireless communication devices (…). Figure 2 (Not shown in the image) provides a non-serving cell. In some examples, another base station (…) Figure 2 (Not shown in the image) can provide non-serving cells and / or serving cells for wireless communication device 202.
[0045] In some examples, wireless communication device 202 may include a receiver configured to receive a message indicating a TCI state. For example, transceiver 206 may receive a message indicating a TCI state. Wireless communication device 202 (e.g., processor 210 and / or TCI state determination controller 208) may be configured to determine the TCI state based on the message, one or more non-serving cell identifiers, and / or one or more received reference signals from non-serving cells. For example, wireless communication device 202 may utilize the received message to identify and / or monitor one or more non-serving cells. In some examples, non-serving cell identifiers may be included in the message and / or the message may indicate one or more non-serving cells for monitoring (e.g., an indicator and / or list of non-serving cells). Wireless communication device 202 (e.g., multiple antennas 204 and / or transceiver 206) can monitor and / or receive one or more reference signals (e.g., multiple CSI-RS, multiple TRS, and / or multiple SSB, etc.) from one or more non-serving cells indicated by one or more non-serving cell identifiers. In some examples, the multiple received reference signals may be one or more CSI-RS, one or more SSB, and / or one or more TRS, etc. In some examples, the one or more received reference signals from one or more non-serving cells may be one or more source reference signals for determining and / or defining QCL information (e.g., QCL-info) for the TCI states. For example, the source reference signal may be a reference signal for defining QCL information for the TCI states. In some examples, determining the TCI state may include determining and / or defining QCL information for the TCI state based on the received reference signals (e.g., from non-serving cells). A reference signal (e.g., a source reference signal) can be represented as an attribute of the TCI state. For example, the TCI state may include the attribute "referenceSignal", which can be used to represent the received reference signal (e.g., the source reference signal).
[0046] In some approaches, the TCI state information element is limited to source reference signals from the same serving cell. In some examples of the techniques described herein, to allow the TCI state to be associated with one or more non-serving cell reference signals, the TCI state (e.g., the TCI information element) may include one or more non-serving cell identifiers. For example, the TCI state may include one or more non-serving cell identifiers.
[0047] In some examples, TCI status information elements may include serving cell and / or non-serving cell identifier information. For example, the TCI status may include QCL information. In some approaches, the QCL information of the TCI status corresponds to non-serving cell information that does not have serving cell information. For example, all QCL information in the TCI status information elements may use a reference signal from the same non-serving cell.
[0048] In some approaches, the QCL information of the TCI state corresponds to one or more non-serving cell identifiers. For example, the TCI state may non-exclusively include QCL information corresponding to (or, for example, QCL information corresponding to (or, for) serving cell identifiers). In some examples, non-serving cell identifier information may be included in QCL information (e.g., each QCL-info). In some approaches, the non-serving cell identifier may be an attribute of the QCL information. For example, the non-serving cell identifier attribute may be included within the QCL information (e.g., the QCL-Info parameter). In some approaches, the non-serving cell identifier is an attribute of a reference signal attribute (e.g., “referenceSignal”) of the QCL information (e.g., in the QCL-Info attribute or parameter). For example, the QCL-Info parameter may include cell attributes, BWP identifier attributes, reference signal attributes, and / or QCL type attributes. The reference signal attribute may include CSI-RS attributes and / or SSB attributes. The non-serving cell identifier can be included within the CSI-RS (e.g., CSI-RS attributes) and / or SSB (e.g., SSB attributes) (e.g., attributes as reference signal attributes). In some approaches, the QCL type of the QCL information indicates that the received reference signal corresponds to a non-serving cell. For example, the QCL type (e.g., Type E) can be used to indicate that the reference signal originates from a non-serving cell.
[0049] List (1) is an example of a TCI status information element. In some of the approaches described herein, one or more non-serving cell identifiers may be incorporated into a TCI status information element as one or more attributes and / or sub-attributes. For example, a non-serving cell identifier attribute (and / or attribute of an attribute) may be added to a TCI status and / or may replace an attribute (and / or attribute of an attribute) of an example of a TCI status shown in List (1).

[0052] Example of non-serving cell status
[0053] In some examples, wireless communication device 202 (e.g., transceiver 206, transmitter, etc.) may be configured to send capability reports indicating TCI state capabilities. In some examples, base station 226 (e.g., base transceiver 216, receiver, etc.) may be configured to receive capability reports indicating TCI state capabilities. TCI state capabilities can be information indicating one or more capabilities used by wireless communication device 202 to process one or more TCI states associated with one or more non-serving cells. For example, wireless communication device 202 may have capabilities for managing (e.g., monitoring, maintaining, recording, reporting, etc.) one or more TCI states for one or more non-serving cells. In some examples, capabilities may be represented as categories, where each category may establish a minimum and / or maximum number of one or more capabilities supported for that category. In some examples, wireless communication device 202 (e.g., UE) may report (multiple) capabilities to base station 226 (e.g., gNB).
[0054] In some examples, the TCI state capability can indicate the maximum number of TCI states for the serving cell and non-serving cells. For example, wireless communication device 202 can report a maximum number of TCI states, which includes any and multiple TCI states for the serving cell(s) and non-serving cells(s).
[0055] In some examples, the wireless communication device 202 can report the TCI state capability for non-serving cells. For example, the TCI state capability can indicate the maximum number of TCI states for non-serving cells. For example, the TCI state capability can indicate the maximum total number of TCI states for all (multiple) non-serving cells. In one example, the wireless communication device 202 may be able to support up to 64 TCI states in total for all non-serving cells.
[0056] In some examples, the TCI state capability can indicate the maximum number of TCI states per non-serving cell. For example, the TCI state capability can indicate the maximum number of TCI states per non-serving cell. In one example, the wireless communication device 202 may be able to support up to 8 TCI states per non-serving cell.
[0057] In some examples, the TCI state capability can indicate the maximum number of non-serving cells having reference signals configured for TCI state association. Non-serving cells can be identified, for example, by their Physical Cell ID (PCI). Therefore, the TCI state capability can indicate the maximum number of PCIs different from the serving cell PCI associated with an active TCI state. For example, the TCI state capability can indicate the maximum number of non-serving cells having corresponding reference signals configured for a TCI state. In one example, wireless communication device 202 may be able to support up to eight non-serving cells having reference signals for one or more TCI states. In another example, wireless communication device 202 may be able to support one PCI different from the serving cell PCI having corresponding reference signals configured for an active TCI state.
[0058] In some examples, separate numbering spaces (e.g., different numerical ranges) can be used for one or more TCI states associated with the serving cell reference signal and for TCI states associated with the non-serving cell reference signal. For example, each TCI state may have an associated TCI state identifier. A first TCI state identifier numbering space for the serving cell may be separate from a second TCI state identifier numbering space for the non-serving cell. In some approaches, the TCI states associated with the non-serving cell reference signals may follow different update and / or activation rules, and / or may be subject to different capability constraints. The TCI states associated with the non-serving cell reference signals may be numbered using a separate TCI state identifier space from the TCI states of the serving cell reference signal. For example, the TCI states of the serving cell reference signal may be numbered using TCI state identifiers in the range of 0–63, and the TCI states of the non-serving cells may be numbered using TCI state identifiers in the range of 64–127.
[0059] In some examples, the TCI status identifier numbering space can be shared for one or more serving cells and / or one or more non-serving cells. For example, all TCI status identifiers can share the same numbering space.
[0060] In some examples, one or more restrictions may be imposed on reference signals (e.g., source reference signals) used for monitoring. For example, wireless communication device 202 may monitor a limited and / or restricted set of reference signals. In some examples, the set of monitored reference signals may be a set of reference signals that can be used to determine the TCI state. For example, only one or more reference signals in the set of monitored reference signals may be used as multiple source references for the TCI state. For example, the set of monitored reference signals corresponding to one or more non-serving cells may be based on the frequency range of serving cell reference signals and / or the capabilities of the wireless communication device. In some approaches, one or more restrictions may be utilized based on the BWP and / or frequency location of the non-serving cell reference signals. For example, based on the capabilities of wireless communication device 202 (e.g., UE), reference signals within the same frequency range (e.g., BWP and / or multiple frequency locations) of the serving cell reference signals may be used as non-serving cell reference signals. In-frequency monitoring for non-serving cells may refer to a monitoring set of one or more non-serving cell reference information included within a frequency range (e.g., BWP) encompassing one or more serving cell reference signals.
[0061] In some examples, the set of monitoring reference signals corresponding to one or more non-serving cells may include one or more reference signals outside the frequency range that includes one or more serving cell reference signals (e.g., not included in that frequency range). Inter-frequency monitoring for non-serving cells may refer to the monitoring set of one or more non-serving cell reference information outside the frequency range (e.g., BWP) that includes one or more serving cell reference signals. In some examples, intra-frequency monitoring may be supported by a lower wireless communication device capability category compared to the wireless communication device capability category that supports inter-frequency monitoring.
[0062] In some examples, the set of monitoring reference signals for sublayer 3 mobility corresponding to one or more non-serving cells can be based on a set of received reference signal identifiers. For example, base station 226 can transmit and / or wireless communication device 202 can receive the set of reference signal identifiers. The set of reference signal identifiers can be transmitted in a message for layer 3 (L3) monitoring, but can be remade for sublayer 3 (e.g., L1 and / or L2) mobility. In some approaches, the wireless communication device can monitor reference signals from other cells. For example, information elements (e.g., MeasObjectNR) can indicate the configuration of reference signal measurements for other cells. Information elements (e.g., ReferenceSignalConfig) can provide a list of SSBs and / or CSI-RS that the wireless communication device can measure. In some examples of the techniques described herein, not all non-serving cell reference signals can be configured as source references for TCI status. For example, qualified non-serving cell reference signals can include non-serving cell reference signals configured in the monitoring reference signal set (e.g., a list). An example of the monitoring reference signal set can include the information element ReferenceSignalConfig from the serving cell (e.g., base station 226). In one example, assume the serving cell is cell 0, and cell 2's SSB1 is configured in the list in ReferenceSignalConfig. Cell 2's SSB1 can be used as the source reference signal for the TCI state in cell 0. For example, the TCI state (TCI1) associated with a non-serving cell can be defined using cell 2's SSB1 as the source reference signal.
[0063] In some examples, the set of monitoring reference signals corresponding to one or more non-serving cells can be based on the serving cell's TCI state. For example, the set of monitoring reference signals may include one or more non-serving cell reference signals that are the target reference signal for the serving cell's TCI state. The target reference signal may be a reference signal corresponding to a non-serving cell for which a potential handover is expected. In one example, in cell 0, CSI-RS0 may be defined using TCI1 (e.g., CSI-RS0 may be the target reference signal for TCI1). Therefore, CSI-RS0 can be used as the source reference signal for the TCI state associated with the non-serving cell.
[0064] In some examples, wireless communication device 202 (e.g., processor 210 and / or TCI state determination controller 208, etc.) may be configured to select a reference signal (e.g., a source reference signal) from a qualified set of reference signals. For example, in some approaches, the source reference signal for the TCI state associated with a non-serving cell may be selected only from a qualified set of reference signals. The qualified set of reference signals may be a set of reference signals from which a source reference signal can be selected. In some cases, the qualified set of reference signals may be different from, similar to, or the same as the monitored set of reference signals. For example, there may be a situation where wireless communication device 202 can monitor one or more inter-frequency reference signals (e.g., a set of reference signals including one or more reference signals outside the frequency range of one or more serving cell reference signals), while only intra-frequency reference signals (e.g., reference signals within the frequency range of one or more serving cell reference signals) may be selected and / or used as the source reference signal.
[0065] In some examples, the wireless communication device 202 (e.g., processor 210 and / or TCI state determination controller 208, etc.) can be configured to determine a qualified set of reference signals. In some approaches, the wireless communication device 202 (e.g., processor 210 and / or TCI state determination controller 208, etc.) can be configured to determine a qualified set of reference signals based on a monitored set of reference signals. For example, the qualified set of reference signals may be a monitored set of reference signals, which can be determined as described above.
[0066] In some approaches, wireless communication device 202 (e.g., processor 210 and / or TCI state determination controller 208, etc.) can be configured to determine a qualified set of reference signals based on the frequency range of the serving cell reference signal and / or the capabilities of the wireless communication device. For example, the qualified set can be limited based on the BWP and / or frequency location of (multiple) non-serving cell reference signals. For example, based on the capabilities of wireless communication device 202 (e.g., UE), reference signals within the same frequency range (e.g., BWP and / or (multiple) frequency locations) of (multiple) serving cell reference signals can be used as (multiple) qualified non-serving cell reference signals. The qualified set of reference signals (e.g., one or more non-serving cell reference signals) can be determined as non-serving cell reference signals (e.g., in-frequency reference signals) included within the frequency range (e.g., BWP) that includes one or more serving cell reference signals.
[0067] In some examples, a qualified set of reference signals can be determined to include one or more non-serving cell reference signals (e.g., inter-frequency reference signals) that are outside (e.g., not included in) a frequency range that includes one or more serving cell reference signals. The qualified set of reference signals may include inter-frequency reference signals(s) and / or intra-frequency reference signals(s) corresponding to one or more non-serving cells. In some examples, the qualified set of reference signals may include one or more non-serving cell reference signals that are outside a frequency range (e.g., BWP) that includes one or more serving cell reference signals. In some examples, a qualified set of intra-frequency reference signals(s) may be supported by a lower wireless communication device capability category than a wireless communication device capability category that supports a qualified set of inter-frequency reference signals(e.g., with or without intra-frequency reference signals(s).
[0068] In some examples, the qualified set of reference signals for sublayer 3 mobility corresponding to one or more non-serving cells can be determined based on a received set of reference signal identifiers. For example, base station 226 may transmit and / or wireless communication device 202 may receive the set of reference signal identifiers. The set of reference signal identifiers may be transmitted in messages for layer 3 (L3) monitoring, but may be re-made for sublayer 3 (e.g., L1 and / or L2) mobility. For example, the qualified set of reference signals may be determined (e.g., selected from) based on one or more information elements (e.g., MeasObjectNR and / or ReferenceSignalConfig) that may indicate the configuration of reference signal measurements for other cells and / or provide a list of SSBs and / or CSI-RS that the wireless communication device can measure. For example, qualified non-serving cell reference signals may include non-serving cell reference signals configured by information elements (e.g., a list). An example of a qualified set of reference signals may include the information element ReferenceSignalConfig from the serving cell (e.g., base station 226).
[0069] In some examples, wireless communication device 202 (e.g., processor 210 and / or TCI state determination controller 208, etc.) can be configured to determine a qualified set of reference signals (e.g., corresponding to one or more non-serving cells) based on the serving cell TCI state. For example, the qualified set of reference signals can be determined to include one or more non-serving cell reference signals that are target reference signals of the serving cell TCI state. In some examples, the qualified set of reference signals can be determined based on whether the reference signals of the non-serving cells are quasi-co-located with the serving cell TCI state.
[0070] As a wireless communication device (e.g., a UE) moves, it can use different beams from different base stations (e.g., gNBs). In some examples, the base station and / or the wireless communication device can update the TCI state accordingly. For the TCI state of the serving cell reference signal, the RRC configuration of the TCI state can be updated. In some approaches, downlink control information (DCI) can be used to update the content of the TCI state. In some approaches, a media access control (MAC) control element (MAC-CE) can be used to activate and / or select the TCI state for the PDSCH and / or PDCCH.
[0071] Among the various approaches used to update the TCI state for non-serving cells, DCI and / or MAC-CE can be utilized. Using DCI and / or MAC-CE can reduce latency. As described herein, base station 226 can send and / or wireless communication device 202 can receive messages indicating the TCI state that can be associated with a non-serving cell. In some examples, this message can be a DCI message (for activating and / or updating the TCI state for one or more non-serving cells). Wireless communication device 202 (e.g., processor 210) can be configured to determine an acknowledgment (ACK) in response to a DCI message. Wireless communication device 202 (e.g., transceiver 206) can send an ACK to base station 226 in response to a DCI message. For example, for DCI-based updates and / or activation, wireless communication device 202 (e.g., UE) can send an ACK for the DCI to acknowledge receipt.
[0072] In some examples, the message may be a MAC-CE message. For example, base station 226 may send and / or wireless communication device 202 may receive a MAC-CE message to update and / or activate the TCI state associated with a non-serving cell. In some examples, if MAC-CE and / or DCI-based signaling is not supported for updating and / or activating the TCI state associated with a non-serving cell, wireless communication device 202 (e.g., UE) may utilize RRC-based reconfiguration. For example, base station 226 may send and / or wireless communication device 202 may receive an RRC message to update and / or activate the TCI state associated with a non-serving cell.
[0073] In some examples, updating the TCI state associated with a non-serving cell reference signal may follow one or more procedures. For example, the message may indicate a handover in reference signal associations between reference signals (e.g., between monitored reference signals and / or to a qualified reference signal). Wireless communication device 202 (e.g., processor 210) may be configured to switch reference signal associations between monitored reference signals (e.g., to switch the source reference signal of the TCI state to another reference signal). For example, the message may indicate changing the associated reference signal from RS1 to RS2, where both RS1 and RS2 are configured in the set of monitored reference signals (e.g., a list indicated by ReferenceSignalConfig or ReferenceSignalConfiguration). In some examples, the message may indicate adding a monitored reference signal (and / or a qualified reference signal) and switching the reference signal association (e.g., switching the source reference signal) to the added monitored reference signal (and / or qualified reference signal). Wireless communication device 202 (e.g., transceiver 206, receiver, etc.) can be configured to receive signaling (e.g., a message sent from base station 226, such as base station 226) for indicative of a reference signal switch (e.g., a switch to a source reference signal). Wireless communication device 202 (e.g., processor 210) can be configured to add monitored reference signals and associate reference signals (e.g., switch the source reference signal) with the added monitored reference signals. For example, an update may include changing the associated reference signal from RS1 to RS2, where RS2 is not yet in the set of monitored reference signals, and the set of monitored reference signals (e.g., MeasObjectNR in RRC) may be updated to include RS2 initially.
[0074] The monitored reference signal set may include all reference signals that the base station 226 (e.g., gNB) configures the wireless communication device 202 (e.g., UE) to monitor. In some examples, MAC-CE and / or DCI-based signaling may be used to update the non-serving cell reference signal measurement configuration (e.g., the monitored reference signal set). In some examples, the monitored reference signal set (e.g., MeasObject) and the TCI state configuration may be updated using a single message (e.g., update signaling indicated by a MAC-CE message or DCI message). In some approaches, updating the MeasObjectNR is performed via RRC reconfiguration.
[0075] In some examples, activation signaling may include one or a combination of DCI, MAC-CE, and / or RRC signaling. In some examples, update signaling may include one or a combination of DCI, MAC-CE, and / or RRC signaling. In some examples, wireless communication device 202 (e.g., UE) may report the capability to support its signaling and / or signaling combinations. For TCI updates and / or activations based on DCI and / or MAC-CE, the wireless communication device (e.g., UE) may send an ACK for DCI to base station 226 (e.g., gNB).
[0076] In some examples, updates and / or activation may take effect after the application time. The application time can be a period of time allocated for the wireless communication device to activate and / or update configurations (e.g., TCI state configuration). In some examples, the application time is the period from the time signaling indicating an update is received to the time the update takes effect. In some examples, the application time can be a “beam application time” for the wireless communication device to activate and / or update configurations for one or more beams.
[0077] According to the techniques described herein, one or more methods can be used for beam application timing. In some examples, the application timing for non-serving cell beams can be configured by the base station. For example, beam application timing can be configured by base station 226 (e.g., gNB) based on the capabilities of wireless communication device 202. For example, the capabilities of wireless communication device 202 can be supported by a minimum value for beam application timing.
[0078] In some examples, the application time for non-serving cell beams can be configured by the base station to be greater than or equal to a fixed minimum application time. For example, the beam application time can be configured by base station 226 (e.g., gNB) where the minimum beam application time is fixed and / or predefined.
[0079] In some examples, the application time for non-serving cell beams is fixed. For example, the beam application time can be fixed and / or predefined.
[0080] In some examples, the first application time for a non-serving cell (e.g., a non-serving cell beam) can be separated from the second application time for a serving cell. For example, the application time for updating and / or activating the TCI state associated with a non-serving cell applied by wireless communication device 202 can be different from the application time for the TCI state associated with a serving cell. In some examples, wireless communication device 202 (e.g., UE) can report two separate capabilities to base station 226 (e.g., the capability for application time for (multiple) non-serving cells and the capability for application time for (multiple) serving cells). In some examples, base station 226 (e.g., gNB) can indicate two separate application times to wireless communication device 202 (e.g., the first application time for (multiple) non-serving cells and the second application time for (multiple) serving cells). For example, the application time for (multiple) serving cells can be 3 milliseconds, and / or the application time for (multiple) non-serving cells can be the same amount of time or longer (e.g., a fixed time of 5 ms), or it can be based on one or more SSB measurement timing configurations ((multiple) SMTCs). In some configurations, other examples of application time can be used (e.g., within a range such as 0.5ms to 20ms). In some examples, the specification (e.g., the 3GPP specification) can be modified to specify separate values for the application time for (multiple) non-serving cells and (multiple) serving cells. In some examples, the application time for the TCI state associated with a non-serving cell can depend on the SMTC. For example, the application time for (multiple) non-serving cells can vary with the changing SMTC.
[0081] Figure 3 This is a flowchart illustrating an example of a method 300 for one or more non-serving cell states. In some examples, method 300 is performed by a wireless communication device (e.g., regarding...). Figure 2 The wireless communication device 202 described is executed.
[0082] Wireless communication devices can receive message 302, which indicates the TCI status. In some examples, receiving message 302 can be as follows: Figure 2 The message is executed as described. In some examples, the message may instruct one or more non-serving cell identifiers and / or resources to be monitored to determine the TCI status.
[0083] Wireless communication devices can receive 304 reference signals from non-serving cells. In some examples, receiving a 304 reference signal can be as follows: Figure 2The described procedure is performed as follows. For example, a wireless communication device may monitor resources (e.g., multiple time and / or frequency resources, multiple BWPs, etc., which may be indicated by messages used to indicate the TCI status) to receive one or more reference signals from one or more non-serving cells (e.g., multiple base stations).
[0084] Wireless communication devices can determine the 306TCI state based on the message, the non-serving cell identifier, and / or a received reference signal from the non-serving cell. In some examples, determining the 306TCI state can be as follows: Figure 2 The described procedure is performed accordingly. For example, a wireless communication device may use one or more received reference signals from one or more non-serving cells to determine one or more values (e.g., channel state measurement results, channel state information (CSI), SSB, CQI, PMI, and / or RI, etc.). These values may be measured and / or stored to determine the TCI state.
[0085] In some examples, a wireless communication device may utilize the TCI state associated with one or more non-serving cells to perform one or more operations. For example, the wireless communication device may report one or more values of the TCI state associated with one or more non-serving cells. For example, the wireless communication device may send and / or indicate one or more values to a base station (e.g., a serving cell), wherein the one or more values are determined based on monitoring one or more reference signals from one or more non-serving cells. In some examples, the TCI state associated with one or more non-serving cells may be utilized in one or more mobility (e.g., handover) procedures. For example, the wireless communication device may select, indicate, and / or communicate with a non-serving cell to convert the non-serving cell into a serving cell for the wireless communication device. For example, the wireless communication device may select a non-serving cell with the optimal TCI state value for handover. The wireless communication device may send requests to the non-serving cells for connecting to (e.g., entering a connected mode) and / or receiving service from the non-serving cell. In some examples, one or more mobility procedures in the mobility process may be performed at L1 and / or L2 (e.g., sub-L3).
[0086] Figure 4 This is a flowchart illustrating another example of a method 400 for one or more non-serving cell states. In some examples, method 400 is performed by a base station (e.g., regarding...). Figure 2 The described base station 226) is executed.
[0087] The base station can determine the configuration for 402 for TCI states (e.g., TCI states associated with one or more non-serving cells). In some examples, determining the configuration for 402 for TCI states could be as follows: Figure 2 The description is used to execute it.
[0088] A base station can send a 404 message indicating the TCI status, where the message is used to determine the TCI status based on the non-serving cell identifier and a reference signal from the non-serving cell. In some examples, sending a 404 message could be as follows: Figure 2 The message is executed as described. In some examples, the message may include and / or indicate one or more non-serving cell identifiers.
[0089] In some examples, a base station may perform one or more operations based on the TCI state associated with one or more non-serving cells. For example, the base station may receive reports of one or more values of the TCI state associated with one or more non-serving cells. For example, the base station may receive one or more values and / or indications of one or more values from a wireless communication device, wherein one or more values are determined based on monitoring one or more reference signals from one or more non-serving cells. In some examples, the TCI state associated with one or more non-serving cells may be utilized in one or more mobility (e.g., handover) procedures. For example, the base station may communicate with a wireless communication device for one or more mobility procedures. For example, the wireless communication device may hand over to another cell (e.g., a non-serving cell or a base station) with the optimal TCI state value for handover. In some examples, one or more mobility procedures in the mobility process may be performed at L1 and / or L2 (e.g., sub-L3).
[0090] Figure 5 This is a thread diagram illustrating examples of the utilization of one or more non-serving cell states according to some of the techniques described herein. Figure 5 Wireless communication device 532 is shown. Wireless communication device 532 can be related to... Figure 2 An example of the described wireless communication device 202. Figure 5 Serving cell 530 is also shown. Serving cell 530 can be provided by a base station (e.g., regarding...). Figure 2 The described base station 226 or another base station) is provided. Figure 5 Non-serving cell 534 is also shown. Non-serving cell 534 can be generated by a base station (e.g., regarding...). Figure 2 The description of base station 226 or another base station is provided. In some examples, regarding... Figure 5 One or more of the described functions and / or operations can be as follows: Figures 1-4 It is performed by describing one or more graphs in the diagram.
[0091] In this example, serving cell 530 sends a TCI status message 536 to wireless communication device 532. For example, TCI status message 536 may indicate the TCI status associated with one or more non-serving cells (e.g., non-serving cell 534). In some examples, TCI status message 536 may be sent as a DCI message, MAC-CE message, and / or RRC message. In some pathways, DCI messages and / or MAC-CE messages may be sublayer 3 messages. In some examples, TCI status message 536 may indicate one or more non-serving cell identifiers and / or one or more resources used for reference signal monitoring. Upon receiving TCI status message 536, wireless communication device 532 may update and / or activate (e.g., configure) the TCI status during the application time.
[0092] The serving cell 530 can transmit a serving cell reference signal 538. For example, the serving cell 530 can transmit CSI-RS, SSB, and / or TRS corresponding to the serving cell 530 to the wireless communication device 532.
[0093] Non-serving cell 534 can transmit non-serving cell reference signal 540. For example, non-serving cell 534 can transmit CSI-RS, SSB, and / or TRS corresponding to non-serving cell 534. Wireless communication device 532 can receive non-serving cell reference signal 540.
[0094] The wireless communication device 532 can perform TCI state determination 542. For example, the wireless communication device 532 can determine the TCI state based on the non-serving cell reference signal 540. In some examples, the wireless communication device 532 can determine the TCI state based on the non-serving cell reference signal 540 and the serving cell reference information 538.
[0095] The wireless communication device 532 may perform one or more operations 543 based on the TCI state. For example, the wireless communication device 532 may report one or more values from the TCI state, and / or may perform one or more mobility (e.g., handover) procedures based on the TCI state.
[0096] Figure 6 This is a thread diagram illustrating another example of the utilization of one or more non-serving cell states according to some of the techniques described herein. Figure 6 A wireless communication device 632 is shown. The wireless communication device 632 can be related to... Figure 2 An example of the described wireless communication device 202. Figure 6 Serving cell 630 is also shown. Serving cell 630 can be provided by a base station (e.g., regarding...). Figure 2 The described base station 226 or another base station) is provided. Figure 6 Non-serving cell 634 is also shown. Non-serving cell 634 can be generated by a base station (e.g., regarding...). Figure 2 The description of base station 226 or another base station is provided. In some examples, regarding... Figure 6 One or more of the described functions and / or operations can be as follows: Figures 1-5 It is performed by describing one or more graphs in the diagram.
