Technical Field

[0003] This disclosure generally relates to wireless communication networks, and more particularly to methods and apparatus for multi-beam collision handling in wireless communication systems. Background Technology

[0004] With the rapid growth in demand for transmitting large amounts of data to and from mobile communication devices, traditional mobile voice communication networks have evolved into networks that communicate using Internet Protocol (IP) data packets. This IP data packet communication can provide users of mobile communication devices with IP-bearing voice, multimedia, multicast, and video-on-demand communication services.

[0005] An exemplary network architecture is the Evolved Universal Terrestrial Radio Access Network (E-UTRAN). E-UTRAN systems can provide high data throughput to enable the aforementioned IP-based voice and multimedia services. Currently, the 3GPP standards organization is discussing next-generation (e.g., 5G) radio technologies. Therefore, changes to the current core of the 3GPP standards are currently being submitted and considered to facilitate their evolution and completion. Summary of the Invention

[0017] The invention described herein can be applied to or implemented in the exemplary wireless communication systems and apparatus described below. Furthermore, the invention is primarily described in the context of the 3GPP architecture reference model. However, it should be understood that, with the aid of the disclosed information, those skilled in the art can readily adapt and implement aspects of the invention in 3GPP2 network architectures and other network architectures.

[0018] The exemplary wireless communication systems and apparatus described below employ wireless communication systems that support broadcast services. Wireless communication systems are widely deployed to provide various types of communication, such as voice, data, etc. These systems may be based on code division multiple access (CDMA), time division multiple access (TDMA), orthogonal frequency division multiple access (OFDMA), 3GPP Long Term Evolution (LTE) radio access, 3GPP Long Term Evolution Advanced (LTE-A) radio access, 3GPP2 Ultra Mobile Broadband (UMB), WiMax, 3GPP New Radio (NR), or some other modulation techniques.

[0019] In particular, the exemplary wireless communication systems and apparatus described below may be designed to support one or more standards, such as those provided by the association referred to herein as the 3GPP, known as the "3rd Generation Partnership Project," including: [1] 3GPP TS 38.211 V15.7.0, "NR Physical Channels and Modulation"; [2] 3GPP TS 38.213 v16.6.0, "NR Physical Layer Procedures for Control"; [3] RP-212707, "Draft SID on the Evolution of NR Duplex Operation"; and [4] 3GPP TS38.214 V17.0.0, "NR Physical Layer Procedures for Data." The standards and documents listed above are hereby expressly and wholly incorporated herein by reference.

[0020] Figure 1 A multiple access wireless communication system according to an embodiment of the present invention is illustrated. Access network 100 (AN) includes multiple antenna groups, one antenna group including antennas 104 and 106, another antenna group including antennas 108 and 110, and a third antenna group including antennas 112 and 114. Figure 1 In this diagram, only two antennas are shown in each antenna group; however, each antenna group can utilize more or fewer antennas. Access terminal (AT) 116 communicates with antennas 112 and 114, which transmit information to AT 116 via forward link 120 and receive information from AT 116 via reverse link 118. AT 122 communicates with antennas 106 and 108, which transmit information to AT 122 via forward link 126 and receive information from AT 122 via reverse link 124. In an FDD system, communication links 118, 120, 124, and 126 can communicate using different frequencies. For example, forward link 120 can use a frequency different from that used by reverse link 118.

[0021] Each group of antennas and / or the area in which they are designed to communicate is often referred to as a sector of the access network. In an embodiment, each antenna group is designed to communicate with an access terminal in a sector of the area covered by access network 100.

[0022] In communications via forward links 120 and 126, the transmit antennas of access network 100 can utilize beamforming to improve the signal-to-noise ratio of the forward links used for different access terminals 116 and 122. Furthermore, compared to an access network that transmits to all its access terminals via a single antenna, an access network that uses beamforming to transmit to access terminals randomly distributed within its coverage area typically causes less interference to access terminals in adjacent cells.

[0023] AN can refer to a fixed station or base station used for communication with terminals, and may also be called an access point, Node B, base station, enhanced base station, eNodeB, or some other term. AT can also be called User Equipment (UE), wireless communication device, terminal, access terminal, or some other term.

[0024] Figure 2This is a simplified block diagram of an embodiment of the transmitter system 210 (also referred to as the access network) and receiver system 250 (also referred to as the access terminal (AT) or user equipment (UE)) in the MIMO system 200. At the transmitter system 210, service data for multiple data streams is provided from the data source 212 to the transmit (TX) data processor 214.

[0025] In one embodiment, each data stream is transmitted via a corresponding transmit antenna. The TX data processor 214 formats, decodes, and interleaves the service data of the data streams based on a specific decoding scheme selected for each data stream to provide decoded data.

[0026] OFDM technology can be used to multiplex the decoded data and pilot data of each data stream. The pilot data is typically a known data pattern processed in a known manner and can be used at the receiver system to estimate the channel response. The multiplexed pilot and decoded data for said data stream are then modulated (e.g., symbol mapping) based on a specific modulation scheme (e.g., BPSK, QPSK, M-PSK, or M-QAM) selected for each data stream to provide modulated symbols. The data rate, decoding, and modulation for each data stream can be determined by instructions executed by processor 230. Memory 232 is coupled to processor 230.

[0027] The modulation symbols of all data streams are then provided to the TX MIMO processor 220, which can further process the modulation symbols (e.g., for OFDM). The TX MIMO processor 220 then... T A modulation symbol stream is provided to N T Transmitters (TMTRs) 222a to 222t. In some embodiments, the TX MIMO processor 220 applies beamforming weights to symbols of the data stream and the antennas from which the symbols are transmitted.

[0028] Each transmitter 222 receives and processes a corresponding symbol stream to provide one or more analog signals, and further modulates (e.g., amplifies, filters, and up-converts) the analog signals to provide modulated signals suitable for transmission via a MIMO channel. Then, from N... T Antennas 224a to 224t transmit N from transmitters 222a to 222t. T A modulated signal.

[0029] At receiver system 250, by N REach antenna 252a to 252r receives the transmitted modulated signal and provides the signal received from each antenna 252 to a corresponding receiver (RCVR) 254a to 254r. Each receiver 254 modulates (e.g., filters, amplifies, and down-converts) the corresponding received signal, digitizes the modulated signal to provide a sample, and further processes the sample to provide a corresponding "received" symbol stream.

[0030] The RX data processor 260 then uses specific receiver processing technology from N R 254 receivers receive and process N R Each received symbol stream provides N T Each detected symbol stream is then demodulated, deinterleaved, and decoded by the RX data processor 260 to recover the service data used for the data stream. The processing performed by the RX data processor 260 is complementary to the processing performed by the TX MIMO processor 220 and TX data processor 214 at the transmitter system 210.

[0031] Processor 270 periodically determines which pre-decoding matrix to use (discussed below). Processor 270 formulates a reverse link message including a matrix index portion and a rank portion.

[0032] The reverse link message may include various types of information about the communication link and / or the received data stream. The reverse link message is then processed by the TX data processor 238, which also receives service data from multiple data streams from the data source 236; modulated by the modulator 280; regulated by the transmitters 254a to 254r; and transmitted back to the transmitter system 210.

[0033] At transmitter system 210, the modulated signal from receiver system 250 is received by antenna 224, conditioned by receiver 222, demodulated by demodulator 240, and processed by RX data processor 242 to extract the reverse link message transmitted through receiver system 250. Next, processor 230 determines which pre-decoding matrix to use to determine beamforming weights and then processes the extracted message.

[0034] Memory 232 can be used to temporarily store some buffered / calculated data from 240 or 242 via processor 230, some buffered data from 212, or some specific program code. Furthermore, memory 272 can be used to temporarily store some buffered / calculated data from 260 via processor 270, some buffered data from 236, or some specific program code.

The control circuit 306 executes the program code 312 in the memory 310 via the CPU 308, thereby controlling the operation of the communication device 300. The communication device 300 can receive signals input by a user via the input device 302 (e.g., a keyboard or keypad) and can output images and sounds via the output device 304 (e.g., a monitor or speaker). The transceiver 314 is used to receive and transmit wireless signals, pass received signals to the control circuit 306, and wirelessly output signals generated by the control circuit 306.

[0061] 11.1 Time Slot Configuration

[0062] The time slot format includes downlink symbols, uplink symbols, and variable symbols.

[0063] The following applies to each serving cell.

[0064] If tdd-UL-DL-ConfigurationCommon is provided to the UE, then the UE will set the time slot format of each time slot on multiple time slots to...

[0065] If the UE additionally provides tdd-UL-DL-ConfigurationDedicated, then the parameter tdd-UL-DL-ConfigurationDedicated will only cover the variable symbol for each time slot in multiple time slots, as provided by tdd-UL-DL-ConfigurationCommon.

[0066] For each time slot with a corresponding index provided by slotIndex, the UE applies the format provided by the corresponding symbols. The UE does not expect tdd-UL-DL-ConfigurationDedicated to indicate an uplink or downlink symbol, nor does it expect tdd-UL-DL-ConfigurationCommon to indicate a downlink or uplink symbol.

[0067] For each slot configuration provided by tdd-UL-DL-ConfigurationDedicated, the reference SCS configuration is the reference SCS configuration μ provided by tdd-UL-DL-ConfigurationCommon. ref .

[0068] The number of downlink symbols, uplink symbols, and variable symbols in each time slot of the time slot configuration period is determined according to tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated, and is common to each BWP configuration.

[0069] The UE considers that symbols in a time slot indicated as downlink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated are available for reception, and considers that symbols in a time slot indicated as uplink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated are available for transmission.

[0070] For a set of symbols in a time slot that is indicated as variable by tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated (if provided), if the UE is not configured to listen to the PDCCH of DCI format 2_0, or when tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated are not provided to the UE...

[0071] - If the UE receives the corresponding indication in DCI format, then the UE receives PDSCH or CSI-RS in the symbol set of the time slot.

[0072] If the UE receives the corresponding indication of DCI format, RAR UL grant, fallbackRAR UL grant, or successRAR, then the UE transmits PUSCH, PUCCH, PRACH, or SRS in the symbol set of the time slot.

[0073] For single-carrier operation in unpaired spectrum, if the UE does not detect a DCI format indicating to the UE to transmit PUSCH, PUCCH, PRACH, or SRS in at least one symbol of the symbol set of the time slot, then the UE receives PDCCH, PDSCH, CSI-RS, or DL ​​PRS if the UE is configured by a higher layer to receive PDCCH, PDSCH, CSI-RS, or DL ​​PRS in the symbol set of the time slot; otherwise, the UE will not receive PDCCH, PDSCH, CSI-RS, or DL ​​PRS in the symbol set of the time slot.

[0074] For single-carrier operation in unpaired spectrum, if the UE is configured by a higher layer to transmit SRS, PUCCH, PUSCH, or PRACH in the symbol set of a time slot, and the UE detects a DCI format indicating to the UE to receive CSI-RS or PDSCH in a subset of symbols in the symbol set, then

[0075] - If the UE does not indicate the ability of [partial Cancellation], then the first symbol of the UE in the set appears in T relative to the last symbol of the CORESET in DCI format detected by the UE. proc,2 The UE does not anticipate canceling the transmission of PUCCH, PUSCH, or PRACH in the symbol set; otherwise, the UE cancels the actual repetition of PUCCH or PUSCH or PUSCH [6,TS38.214] as determined in Sections 9 and 9.2.5 or Section 6.1 of [6,TS38.214], or cancels the transmission of PRACH in the symbol set.

[0076] - If the UE indicates the capability of [partial Cancellation], then the UE does not expect cancellation in the symbol set relative to the last symbol of the CORESET in DCI format detected by the UE appearing in T. proc,2 The UE cancels the actual repetition of PUCCH, PUSCH, or PRACH in the symbols within the symbol set.

[0077] - The UE does not expect cancellation in the symbol subset relative to the last symbol of the DCI format CORESET detected by the UE appearing in T. proc,2 The UE cancels the transmission of SRS in the remaining symbols of the symbol subset.

[0079] For a set of symbols in a time slot that is indicated to the UE as an uplink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigDedicated, the UE does not receive the PDCCH, PDSCH, or CSI-RS if the PDCCH, PDSCH, or CSI-RS overlaps with the symbol set of the time slot (even if partially).

[0080] For a set of symbols in a time slot that is indicated to the UE as an uplink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, if the UE does not have a measurement slot, then the UE does not receive DL PRS in the symbol set of the time slot.

[0081] For a set of symbols in a time slot that is indicated to the UE as a downlink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigDedicated, the UE does not transmit PUSCH, PUCCH, PRACH, or SRS when the PUSCH, PUCCH, PRACH, or SRS overlaps with the symbol set of the time slot (even if partially).

[0082] For a variable set of symbols indicated to the UE by tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated (if provided) in a time slot, the UE does not expect to receive dedicated higher-layer parameters configured from the UE in the symbol set of the time slot, nor does it expect to receive both dedicated higher-layer parameters configured to be received by the UE in the symbol set of the time slot.

[0083] For single-carrier operation in unpaired spectrum, for the symbol set indicated to the UE by ssb-PositionsInBurst in SIB1 or ssb-PositionsInBurst in ServingCellConfigCommon for the reception of the SS / PBCH block in a time slot, if transmission would overlap with any symbols in said symbol set, then the UE will not transmit PUSCH, PUCCH, or PRACH in the time slot, and the UE will not transmit SRS in said symbol set of the time slot. When provided to the UE, the UE does not expect tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated to indicate the symbol set of the time slot as uplink.

[0084] For the set of symbols corresponding to the effective PRACH timing in the time slot and N before the effective PRACH timing gap Symbols, as described in Section 8.1, will not be received in the slot if the reception would overlap with any symbol from the symbol set described above. The UE does not expect tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated to indicate the symbol set of the slot as downlink.

[0085] For the set of symbols indicated to the UE by pdcch-ConfigSIB1 in the MIB for the CORESET of the Type0-PDCCH CSS set in the time slot, the UE does not expect the set of symbols to be indicated as uplink via tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated.

[0086] If the UE is scheduled by DCI format to receive PDSCH on multiple time slots, and if tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated indicates that for the time slots in the multiple time slots, at least one symbol in the set of symbols scheduled to receive PDSCH for the UE in the time slot is an uplink symbol, then the UE does not receive PDSCH in the time slot.

[0087] If the UE is scheduled by DCI format to transmit PUSCH on multiple time slots, and if tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated indicates that for a time slot in multiple time slots, at least one symbol in the set of symbols scheduled to transmit PUSCH to the UE in the time slot is a downlink symbol, then the UE does not transmit PUSCH in the time slot.

[0088] 11.1.1 UE procedure for determining time slot format

[0089] If the UE is configured by a higher layer using the parameter SlotFormatIndicator, then the UE is provided with SFI-RNTI by sfi-RNTI and the payload size of DCI format 2_0 by dci-PayloadSize.

[0090] The SFI index field value in DCI format 2_0 indicates to the UE the slot format of each slot in a plurality of slots for each DL BWP or each UL BWP, starting from the slot where the UE detects DCI format 2_0. The number of slots is equal to or greater than the PDCCH listening periodicity for DCI format 2_0. The SFI index field contains The unit digit is maxSFIindex, which is the maximum value provided by the corresponding slotFormatCombinationId. The slot format is identified by the corresponding format index provided in Table 11.1.1-1, where 'D' represents a downlink symbol, 'U' represents an uplink symbol, and 'F' represents a variable symbol.

[0091] If the PDCCH monitoring period for DCI format 2_0 provided to the UE for the search space set s via monitoringSlotPeriodicityAndOffset is less than the duration of the slot format combination, then the UE obtains the corresponding SFI index field value at the PDCCH monitoring time for DCI format 2_0, and the UE detects that there is more than one DCI format 2_0 indicating the slot format for the slot, the UE expects each of the more than one DCI format 2_0 to indicate the same format for the slot.

A continuous downlink or variable or uplink symbol.

[0096] For unpaired spectrum operations of the UE on the serving cell relative to the second UL carrier, the SFI-index field value in DCI format 2_0 indicates a combination of time slot formats, which includes a combination of time slot formats of the serving cell's reference first UL carrier and a combination of time slot formats of the serving cell's reference second UL carrier. For the serving cell's reference first UL carrier, for the combination of time slot formats indicated by the SFI-index field in DCI format 2_0, the subcarrierSpacing provides the UE with a reference SCS configuration μ.

[0139] **************************End of quotation***********************************

[0140] Narrow beams are introduced to overcome / compensate for high propagation loss in high-frequency bands. By concentrating transmit power in a specific direction, such as targeting the receiver, the signal quality received at the receiver can be improved to maintain or increase throughput / data rate under high loss. Transmission or reception, or both, can be performed using narrow beams. For example, DL transmission can be performed using the base station's Tx beam. User equipment (UE) can receive DL transmissions using the UE's Rx beam, for example, corresponding to or associated with the Tx beam. Proper correspondence or association between the DL transmitter (Tx) beam and the DL receiver (Rx) beam can be maintained by the UE and / or gNB. This is also called a beam pair. Transmission Configuration Indication (TCI) status and / or Quasi-Colocation (QCL) assumptions can be used to identify such beam relationships, for example, to indicate DL Tx beams or DL ​​Rx beams. A TCI state can be associated with a DL reference signal (RS), such as a Synchronization Signal Block (SSB) (e.g., Synchronization Signal / Physical Broadcast Channel (SS / PBCH)) or a Channel State Information Reference Signal (CSI-RS). The DL RS can be transmitted using a base station beam. The gNB can instruct the DL transmission to be transmitted in a TCI state (e.g., in QCL type D). The UE can implement the DL transmission using a base station beam (e.g., a DL Tx beam) that is identical to the base station beam used for the DL RS associated with the TCI state. The UE will then be able to receive the DL transmission using a UE beam (e.g., a DL Rx beam) corresponding to the base station beam (e.g., given a UE, learning which UE beam corresponds to which DL RS (base station beam) based on measurements of the DL RS and different UE beams). Similarly, the TCI status can be used to indicate the UL Tx beam (UE beam) and / or the UL Rx beam (base station beam). The Service Request Indicator (SRI) can also be used to indicate the UL beam. The SRI can be associated with the Sounding Reference Signal (SRS) when it is transmitted using the UE beam (UL Tx beam).When the base station instructs to use SRI to transmit UL transmission, the UE will use the same beam used to transmit UL transmission to transmit SRS at the time associated with SRI (e.g., given that the base station learns which gNB beam (e.g., UL Rx beam) corresponds to which SRS (UE beam) based on measurements of SRS and different gNB beams). Further details related to beam operation are given below from [4] 3GPP TS 38.214 V17.0.0, “NR Physical Layer Procedure for Data”:

[0142] 5.1.5 Quasi-co-addressable antenna ports

[0143] The UE can be configured with a list of up to M TCI-State configurations within the higher-layer parameter PDSCH-Config to decode the PDSCH based on the detected PDCCH with a predetermined DCI for the UE and a given serving cell, where M depends on the UE capability maxNumberConfiguredTCIstatesPerCC. The UE can also be configured with a list of up to M TCI-State configurations within the higher-layer parameter PDSCH-Config-Multicast to decode the PDSCH associated with a G-RNTI or G-CS-RNTI based on the detected PDCCH with a predetermined DCI for the UE and a given serving cell, where M' depends on the UE capability. Each TCI-State contains parameters for configuring a quasi-co-address relationship between one or two downlink reference signals and the DM-RS port of the PDSCH, the DM-RS port of the PDCCH, or the CSI-RS port of the CSI-RS resource. The quasi-co-address relationship is configured via the higher-layer parameter qcl-Type1 for the first DL RS and the higher-layer parameter qcl-Type2 for the second DL RS (if configured). In the case of two DL RSs, the QCL type will differ, regardless of whether the reference is for the same or different DL RSs. The quasi-co-address type corresponding to each DL RS is given by the higher-level parameter qcl-Type in QCL-Info and can take one of the following values:

[0144] -'Type A': {Doppler shift, Doppler spread, average delay, delay spread}

[0145] -'Type B': {Doppler frequency shift, Doppler spread}

[0146] -'Type C': {Doppler shift, average delay}

[0147] -'Type D': {Space Rx parameter}

[0148] The UE can be configured with a list of up to

[128] [TCI-State] configurations within the higher-layer parameter PDSCH-Config, where [tci-StateId_r17] contains [SourceRs-Info_r17], used to provide a reference signal for quasi-co-addressing of the DM-RS of the PDSCH and the DM-RS of the PDCCH in the CC and CSI-RS, and to provide a reference (if applicable) for determining the UL TX spatial filters in the CC and SRS for PUSCH and PUCCH resources based on dynamic and configuration-approved PUSCH and PUCCH resources. If no [TCI-State] configuration exists in the BWP of the CC, the UE can apply the [TCI-State] configuration from the reference BWP of the reference CC.

[0149] The UE receives an activation command, as described in Section 6.1.3.14 of [10, TS 38.321] or Section 6.1.3.x of [10, TS 38.321], to map up to eight TCI states and / or TCI state pairs to code points in the DCI field 'Transmission Configuration Indication' for one or more CC / DL BWP sets and (if applicable) one or more CC / UL BPW sets, where one TCI state is for a DL channel / signal and one TCI state is for a UL channel / signal. When the TCI state ID set is activated for the CC / DL BWP set and (if applicable) for the CC / UL BWP set, the applicable list of CCs is determined by the CCs indicated in the activation command, and the same TCI state ID set is applied to all DL and / or UL BWPs in the indicated CCs.

[0150] If the UE is configured with the higher-layer parameter tci-PresentInDCI set to 'enabled' for scheduling PDSCH, then the UE assumes that the TCI field exists in DCI format 1_1 of the PDCCH transmitted on the CORESET. If the UE is configured with the higher-layer parameter tci-PresentDCI-1-2 for scheduling PDSCH, then the UE assumes that the TCI field with the DCI field size indicated by tci-PresentDCI-1-2 exists in DCI format 1_2 of the PDCCH transmitted on the CORESET. If PDSCH is scheduled via a DCI format that does not have a TCI field, and the time offset between the reception of DL DCI and the corresponding PDSCH of the serving cell is equal to or greater than the threshold timeDurationForQCL (if applicable), where the threshold is based on the reported UE capability [13, TS 38.306], in order to determine the PDSCH antenna port quasi-co-address, the UE assumes that the TCI state or QCL assumption for PDSCH is the same as the TCI state or QCL assumption applied to the CORESET for PDCCH transmission within the BWP in the serving cell (whichever is correct).

[0151] If the PDSCH is scheduled using a DCI format with a TCI field, then the TCI field in the DCI of the scheduled component carrier points to the active TCI state in the scheduled component carrier or DL ​​BWP. The UE should use the TCI-State, based on the value of the 'Transmission Configuration Indication' field in the detected PDCCH with DCI, to determine the quasi-co-addressable antenna port of the PDSCH. If the time offset between the reception of the DLDCI and the corresponding PDSCH is equal to or greater than the threshold timeDurationForQCL, then the UE may assume that the DM-RS port of the serving cell's PDSCH is quasi-co-addressable with the RS in the TCI state, relative to the QCL type parameter given by the indicated TCI state, where the threshold is based on the reported UE capability [13, TS 38.306]. When the UE is configured with a single-slot PDSCH, the indicated TCI state should be based on the active TCI state in the slot with the scheduled PDSCH. When a UE is configured with a multi-slot PDSCH, the indicated TCI state should be based on the active TCI state in the first slot with the scheduled PDSCH, and the UE should expect that the active TCI state is the same across the slots with the scheduled PDSCH.

[0153] 6.1 UE program for transmitting physical uplink shared channel

[0154] PUSCH transmissions can be dynamically scheduled by UL grants in the DCI, or the transmissions can correspond to configured grant type 1 or type 2. Configured grant type 1 PUSCH transmissions are semi-statically configured to operate upon receiving a higher-layer parameter `configuredGrantConfig` containing `rrc-ConfiguredUplinkGrant`, without detecting UL grants in the DCI. Upon receiving a higher-layer parameter `configuredGrantConfig` that does not contain `rrc-ConfiguredUplinkGrant`, configured grant type 2 PUSCH transmissions are semi-statically scheduled by the effectively activated UL grants in the DCI according to Section 10.2 of [6, TS 38.213]. If `configuredGrantConfigToAddModList` is configured, then more than one configured grant type 1 and / or configured grant type 2 can be simultaneously active on the serving cell's active BWP.

[0155] When a UE is configured with a [TCI-State] having [tci-StateId_r17] for UL, the UE shall, based on spatial relations (if applicable), execute a PUSCH transmission corresponding to type 1 configured-approved or type 2 configured-approved or dynamically-approved, wherein the reference is an RS used to determine the UL Tx spatial filter or an RS configured with the indicated [TCI-State] having [tci-StateId_r17] and a qcl-Type set to 'typeD'. The referenced RS may be a CSI-RS resource in an NZP-CSI-RS-ResourceSet configured with the higher-layer parameter repetition, a CSI-RS resource in an NZP-CSI-RS-ResourceSet configured with the higher-layer parameter trs-Info, or (where the [TCI-State] having [tci-StateId_r17] is only used for UL) an SRS resource with the higher-layer parameter usage set to 'beamManagement', or an SS / PBCH block associated with a PCI that is the same as or different from the PCI of the serving cell.

[0156] The UE shall transmit the corresponding PUSCH as indicated by the DCI after detecting a PDCCH with a configured DCI format of 0_0, 0_1 or 0_2, unless the UE does not generate a transport block as described in [10, TS 38.321].

[0157] For a PUSCH scheduled in DCI format 0_0 on a cell, the UE should transmit the PUSCH according to the spatial relationship (if applicable) of the dedicated PUCCH resource with the lowest ID within the UL BWP during cell startup, as described in Section 9.2.1 of [6, TS 38.213]. If the dedicated PUCCH resource with the lowest ID within the UL BWP during cell startup corresponds to two spatial relationships, then the UE should transmit the PUSCH according to the spatial relationship with the lowest ID.

[0158] For a PUSCH scheduled by DCI format 0_0 on the cell, and if the higher-layer parameter enableDefaultBeamPL-ForPUSCH0-0 is set to 'enabled', the UE is not configured with PUCCH resources on the launching UL BWP, and the UE is in RRCCONNECTED mode, then the UE should transmit the PUSCH according to spatial relationships (if applicable), where the RS is configured with qcl-Type set to 'typeD', referencing the QCL assumption of the CORESET with the lowest ID on the launching DL BWP corresponding to the cell. If the indicated CORESET has two TCI states, sfnSchemePdcch is configured, and the UE supports [DefaultBeamPL-ForPUSCH-SfnPdcch], then the UE should use the first TCI state as the QCL assumption.

[0159] For a PUSCH scheduled by DCI format 0_0 on a cell, and if the higher-layer parameter enableDefaultBeamPL-ForPUSCH0-0 is set to 'enabled', the UE is configured with all PUCCH resources on the startup UL BWP that are not configured with any spatial relationship, and the UE is in RRC CONNECTED mode, then the UE should transmit the PUSCH according to the spatial relationship (if applicable), wherein, in the case that the CORESET is configured on the cell, the RS with qcl-Type set to 'typeD' is assumed to be configured with reference to the QCL of the CORESET with the lowest ID on the startup DL BWP corresponding to the cell.

[0160] 6.1.1.1 Codebook-based UL transmission

[0161] For codebook-based transmission, PUSCH can be scheduled by DCI format 0_0, DCI format 0_1, DCI format 0_2 or semi-statically configured to operate according to Section 6.1.2.3. If this PUSCH is scheduled by DCI format 0_1, DCI format 0_2, or semi-statically configured to operate according to Section 6.1.2.3, then the UE determines its PUSCH transport predecoder based on SRI, TPMI, and transport class, wherein SRI, TPMI, and transport class are given for DCI formats 0_1 and 0_2 by one or two DCI fields of the SRS resource indicator and one or two predecoding information and layer number in Sections 7.3.1.1.2 and 7.3.1.1.3 of [5, TS 38.212], or by srs-ResourceIndicator and precodingAndNumberOfLayers according to Section 6.1.2.3, or by srs-ResourceIndicator, srs-ResourceIndicator2, precodingAndNumberOfLayers, and precodingAndNumberOfLayers2 according to Section 6.1.2.3. The SRS-ResourceSets applicable to PUSCHs scheduled by DCI format 0_1 ​​and DCI format 0_2 are defined by entries in the higher-level parameters srs-ResourceSetToAddModList and srs-ResourceSetToAddModListDCI-0-2 in the SRS-config, respectively. Only one or two SRS resource sets can be configured in srs-ResourceSetToAddModList where the higher-level parameter usage is set to 'codebook', and only one or two SRS resource sets can be configured in srs-ResourceSetToAddModListDCI-0-2 where the higher-level parameter usage is set to 'codebook'.

[0162] 6.1.1.2 Non-codebook-based UL transmission

[0163] For non-codebook-based transmissions, the PUSCH can be scheduled by DCI format 0_0, DCI format 0_1, or DCI format 0_2, or semi-statically configured to operate according to Section 6.1.2.3. If this PUSCH is scheduled by DCI format 0_1, DCI format 0_2, or semi-statically configured to operate according to Section 6.1.2.3, then the UE can determine its PUSCH pre-decoder and transmission class based on the SRI when multiple SRS resources are configured, wherein the SRI for DCI format 0_1 ​​and DCI format 0_2 is given by one or both SRS resource indicators in the DCI according to Sections 7.3.1.1.2 and 7.3.1.1.3 of [5,38.212], or the SRI is given by the srs-ResourceIndicator according to Section 6.1.2.3, or both SRIs are given by the srs-ResourceIndicator and srs-ResourceIndicator2 according to Section 6.1.2.3. The SRS-ResourceSet applicable to PUSCHs scheduled by DCI format 0_1 ​​and DCI format 0_2 is defined by entries in the higher-layer parameters srs-ResourceSetToAddModList and srs-ResourceSetToAddModListDCI-0-2 in the SRS-config, respectively. The UE should use one or more SRS resources for SRS transmission. Within each SRS resource set, the UE can be configured with the maximum number of SRS resources that can be simultaneously transmitted in the same symbol and the maximum number of SRS resources available for transmission. Transmitted SRS resources occupy the same RB simultaneously. Only one SRS port is configured for each SRS resource. Only one or two SRS resource sets can be configured in srs-ResourceSetToAddModList with the higher-layer parameter usage set to 'nonCodebook' in the SRS-ResourceSet, and only one or two SRS resource sets can be configured in srs-ResourceSetToAddModListDCI-0-2 with the higher-layer parameter usage set to 'nonCodebook' in the SRS-ResourceSet. When two SRS resource sets are configured in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2 with the higher-level parameter usage set to 'nonCodebook' in the SRS-ResourceSet, one or both SRIs are given by the DCI fields of the two SRS resource indicators for DCI formats 0_1 and 0_2 in sections 7.3.1.1.2 and 7.3.1.1.3 of [5, TS 38.212].According to Section 6.1.2.1, the UE applies the indicated SRI to one or more PUSCH repeats based on the associated SRS resource set of the PUSCH repeat. The maximum number of SRS resources per SRS resource set that can be configured for non-codebook-based uplink transmissions is 4. Each of the one or two SRIs indicated in slot n is associated with the most recent transmission of SRS resources in the associated SRS resource set identified by the SRI, where the SRS transmission precedes the PDCCH carrying the SRI. When two SRS resource sets are configured in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2 with the higher-layer parameter usage set to 'nonCodebook' in the SRS-ResourceSet, the UE is not expected to have a different number of SRS resources configured in the two SRS resource sets.

[0164] When a PDCCH candidate is associated with a search space set configured with searchSpaceLinking, the PDCCH candidate that started earlier among the two configured PDCCH candidates is used for the purpose of determining the most recent delivery of the SRS resource identified by SRI.

[0165] For non-codebook-based transmissions, the UE can calculate the pre-decoder for SRS transmission based on measurements of the associated NZP CSI-RS resources. The UE can be configured with only one NZP CSI-RS resource for the SRS resource set, where higher-layer parameters (if configured) are used in the SRS-ResourceSet set set to 'nonCodebook'.

[0166] The UE shall perform a one-to-one mapping from the indicated SRI to the indicated DM-RS port and its corresponding PUSCH layer {0…ν-1} as given by DCI format 0_1 ​​or 0_2 or according to configuredGrantConfig in Section 6.1.2.3 in ascending order.

[0167] The UE shall transmit PUSCH using the same antenna port as the SRS port in the SRS resource indicated by the SRI given by DCI format 0_1 ​​or 0_2 or according to the configuredGrantConfig in Section 6.1.2.3, where the SRS port index of the (i+1)th SRS resource in the SRS resource set is p. i =1000+i.

[0169] Duplex enhancements have been discussed in 3GPP to enable more frequent ULs in order to improve latency and UL coverage. For unpaired spectrum (e.g., TDD), UL and DL transmissions can occur for the same symbol. More details about duplexing can be found below in the reference to the SID draft of NR duplex operation evolution, RP-212707 [3]:

[0170] **************************Start of quotation***********************************

[0171] TDD is widely used in commercial NR deployments. In TDD, time-domain resources are segmented between downlink and uplink. The limited duration allocation of uplinks in TDD leads to reduced coverage and increased latency. As a possible enhancement to this limitation of conventional TDD operation, it is worthwhile to investigate the feasibility of allowing simultaneous downlink and uplink (also known as full-duplex, or more specifically, subband non-overlapping full-duplex) on the gNB side within the conventional TDD band.

[0172] NR TDD allows for dynamic / variable time allocation of downlink and uplink and introduces CLI processing and RIM for NR in Rel-16. Nevertheless, further research is needed on CLI processing between different operator networks to enable dynamic / variable TDD in commercial networks. Depending on the deployment scenario, inter-operator CLI can be due to adjacent channel CLI, co-channel CLI, or both. A major unresolved issue in previous versions was gNB-to-gNB CLI.

[0173] This study aims to identify the feasibility and solutions for duplex evolution in the regions outlined above, to provide enhanced coverage, reduced latency, improved system capacity, and improved configuration flexibility for NR TDD operations in unpaired spectrum.

[0174] In this study, the following assumptions are made:

[0175] • Duplex enhancement on the gNB side

[0176] Half-duplex operation on the UE side

[0177] • No limitation on frequency range

[0178] The detailed objectives are as follows:

[0179] • Investigate subband non-overlapping full-duplex and potential enhancements for dynamic / variable TDD.

[0180] - Identify possible solutions and evaluate their feasibility and performance (RAN1).

[0181] - Study the CLI processing between gNBs and between UEs and identify solutions (RAN1) for managing the processing.

[0182] If necessary, the impact of the aforementioned processing on the gNB inter-interface (RAN3) should be investigated.

[0183] In the case of non-overlapping full-duplex subbands, consider intra-subband CLI and inter-subband CLI.

[0184] - Assuming its coexistence in co-channel and adjacent channels, the study investigates the performance of the identification scheme and its impact on conventional operation (RAN1).

[0185] - Considering self-interference, inter-subband CLI and inter-carrier CLI at the gNB, and inter-subband CLI and inter-carrier CLI at the UE, the impact on RF requirements is studied (RAN4).

[0186] - Considering coexistence with adjacent channels in conventional operation, the impact on RF requirements is investigated (RAN4).

[0187] - Early involvement should extend to RAN4 to provide necessary information to RAN1 as needed and investigate feasibility aspects with high impact in antenna / RF and algorithm design, including inter-antenna isolation, TX IM suppression in the RX section, filtering, and digital interference suppression.

[0188] **************************End of quotation***********************************

[0189] Enhancements to duplex schemes can affect how user equipment (UE) handles downlink (DL) reception or uplink (UL) transmission. For example, for a regular DL symbol (e.g., without duplex enhancement), the UE will not perform UL transmissions on such symbols, such as canceling configured UL transmissions on the symbol, or UL transmissions scheduled by Downlink Control Information (DCI) on the symbol that are not expected (the network (NW) will not perform such scheduling and / or the UE will treat such scheduling as an error). Similar restrictions on DL reception can apply to regular UL symbols. The indicated transmission direction applies to all / all frequency resources of the bandwidth portion / serving cell. However, such restrictions may no longer be effective when a symbol can support more than one transmission direction under duplex enhancement, such as for both DL and UL. For example, the UE may be able to perform UL transmissions on symbols indicated as DL. Whether duplex enhancements are applicable may depend on the isolation between DL transmissions and UL reception at the base station side. For example, when performing DL transmission on one gNB beam and UL reception on another gNB beam, if the two gNB beams have good isolation, for example, when there is little mutual interference, DL transmission and UL reception can be performed simultaneously on the same symbol. In other words, duplex enhancement is applicable. On the other hand, when the two gNB beams do not have good isolation, for example, when there is more mutual interference, DL transmission and UL reception may not be performed simultaneously on the same symbol. Duplex enhancement then is not applicable. Therefore, depending on the different UE behaviors, whether and / or how the UE implements duplex enhancement, how it applies to multiple beams, and how it behaves correctly may require other considerations.

[0190] The first concept of this invention is for the base station to indicate to the UE which beams are suitable for duplex enhancement. On beams where duplex enhancement is not applicable, the transmission direction of a symbol may (only) be one of UL, DL, or a variable, for example, DL across the entire serving cell or bandwidth portion. On beams where duplex enhancement is applicable, the transmission direction of a symbol may be more than one of UL, DL, or a variable, for example, UL on some frequency resources within the serving cell or bandwidth portion and DL on other frequency resources.

[0191] A second concept of the present invention is to associate the transmission direction and / or slot format indicator (SFI) on a symbol with a beam. In one example, a first transmission direction is associated with a first beam and / or a first set of beams. A second transmission direction is associated with a second beam and / or a second set of beams. A first SFI is associated with the first beam and / or the first set of beams. A second SFI is associated with the second beam and / or the second set of beams. The UE performs corresponding actions for receiving / transmitting associated with the first beam and / or the first set of beams based on the first transmission direction and / or the first SFI. The UE performs corresponding actions for receiving / transmitting associated with the second beam and / or the second set of beams based on the second transmission direction and / or the second SFI.

[0192] For example, for a first beam and / or a first set of beams, the UE is instructed to use a DL for a first frequency resource and a UL for a second resource. For a second beam and / or a second set of beams, the UE is instructed to use a DL for a symbol (e.g., for the first frequency resource and / or the second resource). If / when the frequency resource transmitted via configured UL or scheduled UL is within the first frequency resource and / or if / when the UL transmission is associated with the first beam and / or the first set of beams, the UE will cancel the configured UL transmission on the symbol or treat the scheduled UL transmission on the symbol as an error. If / when the frequency resource transmitted via configured UL or scheduled UL is within the second frequency resource and / or if / when the UL transmission is associated with the first beam and / or the first set of beams, the UE will execute the configured UL transmission or scheduled UL transmission on the symbol. If / when a UL transmission is associated with a second beam and / or a second set of beams, the UE will cancel the configured UL transmission on the symbol or treat the scheduled UL transmission on the symbol as an error condition, for example, regardless of whether the frequency resources for the configured UL transmission or the scheduled UL transmission are within the first frequency resources and / or the second frequency resources.

[0193] In another example, for a first beam and / or a first set of beams, a first transmission direction is associated with a first frequency resource. For the first beam and / or the first set of beams, the first transmission direction is not associated with a second frequency resource. For a second beam and / or a second set of beams, a second transmission direction is associated with the first frequency resource and / or the second frequency resource. The second transmission direction may be the same as the first transmission direction. The second transmission direction may be different from the first transmission direction.

[0194] If / when receiving / transmitting is associated with a first beam and / or a first set of beams, the UE performs the corresponding action for receiving / transmitting within a first frequency resource based on a first transmission direction. If / when receiving / transmitting is associated with a first beam and / or a first set of beams, the UE does not perform the corresponding action for receiving / transmitting within a second frequency resource based on the first transmission direction. If / when receiving / transmitting is associated with a second beam and / or a second set of beams, the UE performs the corresponding action for receiving / transmitting based on a second transmission direction (e.g., regardless of whether it is within the first frequency resource and / or the second frequency resource).

[0195] For example, the UE is instructed to specify a DL for a first frequency resource for a symbol for a first beam. The UE is instructed to specify a second frequency resource for a symbol that the DL should not be applied to. The UE is instructed to specify a symbol (e.g., for the first and / or second frequency resources) that the DL is applied to. If / when the frequency resource transmitted via a configured UL or a scheduled UL is within the first frequency resource and / or if / when the UL transmission is associated with the first beam, the UE will cancel the configured UL transmission on the symbol or treat the scheduled UL transmission on the symbol as an error. If / when the frequency resource transmitted via a configured UL or a scheduled UL is within the second frequency resource and / or if / when the UL transmission is associated with the first beam, the UE behaves as if no DL is indicated for the symbol transmitted via a configured UL or a scheduled UL. If / when the frequency resource transmitted via a configured UL or a scheduled UL is within the second frequency resource and / or if / when the UL transmission is associated with the first beam, the UE will execute the configured UL transmission or the scheduled UL transmission on the symbol. If / when a UL transmission is associated with a second beam, the UE will cancel the configured UL transmission on the symbol or treat the scheduled UL transmission on the symbol as an error, regardless of whether the frequency resources for the configured UL transmission or the scheduled UL transmission are within the first frequency resource and / or the second frequency resource.

[0196] The first frequency resource and / or the second frequency resource may be resources within the bandwidth portion and / or the serving cell. The first frequency resource and / or the second frequency resource may be all / all resources within the bandwidth portion and / or the serving cell. Both the first frequency resource and the second frequency resource may be indicated to the UE. One of the first frequency resource and the second frequency resource may be indicated to the UE and the UE may derive the other (e.g., indicating the first frequency resource to the UE, and the frequency resource of the serving cell / bandwidth portion not within the first frequency resource is the second frequency resource). The second frequency resource may be indicated to the UE, and the frequency resource of the serving cell / bandwidth portion not within the second frequency resource is the first frequency resource. The UE may anticipate that reception / transmission will be within the range of the first frequency resource or the second frequency resource. The base station should configure or schedule transmission / reception such that the frequency resource for transmission / reception will be within the range of the first frequency resource or the second frequency resource. The base station should configure or schedule transmission / reception such that the frequency resource for transmission / reception does not cross the first frequency resource and the second frequency resource. When the frequency resource for transmission / reception crosses the first frequency resource and the second frequency resource, the UE may take one of the actions / behaviors related to the first frequency resource / second frequency resource (e.g., as described above). For example, if the UE cancels reception / transmission in any part of a frequency resource, for instance, because the frequency resource for receiving / transmitting overlaps with a first frequency resource or a second frequency resource, then the UE cancels all reception / transmission (e.g., not just a part). When the frequency resource for transmitting / receiving spans a first frequency resource and a second frequency resource, the UE may take separate actions / behaviors for the different frequency resources used for transmission / reception (e.g., canceling transmission / reception in a part of the frequency resource for transmission / reception, and performing transmission / reception in another part of the frequency resource for transmission / reception).

[0197] The association between an SFI / transmission direction and a beam (or beam set) can be indicated from the base station to the UE. This association can be indicated via Radio Resource Control (RRC) signaling configuration and / or via a Medium Access Control (MAC) control element (MAC CE). The association can also be indicated via a DCI. The DCI can be periodically monitored. The DCI indicates the association's duration for a certain period. When the association changes, the DCI updates the association. The association can be indicated together with the SFI. The association can also be indicated separately from the SFI. For example, the first SFI—Radio Network Temporary Identifier (RNTI) and / or the first location in the SFI field can be associated with a first beam and / or a first set of beams. The second SFI—RNTI and / or the second location in the SFI field can be associated with a second beam and / or a second set of beams. The SFI indicated by the DCI associated with the first SFI—RNTI and / or the first location in the SFI field can be associated with a first frequency resource. An SFI indicated by a DCI associated with a second SFI-RNTI and / or a second position in the SFI field may be associated with a second frequency resource. A bitmap associated with the SFI may be used to indicate the beam and / or beam set associated with the SFI. A Resource Indicator Value (RIV) associated with the SFI may be used to indicate the beam and / or beam set associated with the SFI. A bandwidth portion associated with the SFI may be used to indicate the beam and / or beam set associated with the SFI. The start position and length may be used to indicate a first frequency resource and / or a second frequency resource. The start Physical Resource Block (PRB) and bandwidth may be used to indicate a first frequency resource and / or a second frequency resource.

[0198] The base station can indicate the association between the SFI / transmission direction and frequency resources to the UE. This association can be configured via RRC signaling and / or indicated via MAC CE. The association can also be indicated via DCI. The DCI can be periodically monitored. The DCI indicates the association's duration for a certain period. When the association changes, the DCI updates the association. The association can be indicated together with the SFI. The association can also be indicated separately from the SFI. For example, the first SFI-RNTI and / or the first position of the SFI field can be associated with a first frequency resource. The second SFI-RNTI and / or the second position of the SFI field can be associated with a second frequency resource. The SFI indicated by the DCI associated with the first SFI-RNTI and / or the first position of the SFI field can be associated with the first frequency resource. The SFI indicated by the DCI associated with the second SFI-RNTI and / or the second position of the SFI field can be associated with the second frequency resource. The bitmap associated with the SFI can be used to indicate the frequency resource associated with the SFI. The RIV value associated with the SFI can be used to indicate the frequency resource associated with the SFI. The bandwidth portion associated with the SFI can be used to indicate the frequency resource associated with the SFI. The starting position and length can be used to indicate the first frequency resource and / or the second frequency resource. The starting PRB and bandwidth can be used to indicate the first frequency resource and / or the second frequency resource.

[0199] In one embodiment, the UE receives an indication of whether duplex enhancement applies to a beam (or beam set). The indication may indicate which beams and / or beam sets the duplex enhancement applies to. The indication may also indicate which beams and / or beam sets the duplex enhancement does not apply to. The indication may indicate that the duplex enhancement applies to a first beam and / or a first set of beams. The indication may also indicate that the duplex enhancement applies to a second beam and / or a second set of beams. A first frequency resource is associated with a first SFI. For the second beam and / or the second set of beams, the UE does not receive an indication of the first frequency resource from the base station. The UE receives a first SFI from the base station for the first beam and / or the first set of beams. When reception / transmission is associated with the first beam and / or the first set of beams, or if reception / transmission is associated with the first beam and / or the first set of beams, then the UE processes its frequency resources for reception / transmission within the first frequency resource based on the first SFI. When a receive / transmit is associated with a first beam and / or a first set of beams, the UE does not process a receive / transmit whose frequency resource is not within the first frequency resource based on the first SFI. When a receive / transmit is associated with a first beam and / or a first set of beams, the UE processes a receive / transmit whose frequency resource is not within the first frequency resource as if no first SFI is indicated. When a receive / transmit is associated with a first beam and / or a first set of beams, if the first SFI indicates a symbol as UL and the configured receive frequency resource is within the first frequency resource, the UE cancels the configured (DL) receive on the symbol. When receiving / transmitting is associated with a first beam and / or a first set of beams, if the first SFI indicates a symbol as UL and the frequency resource for configured reception is not within the first frequency resource, the UE performs a symbol-configured (DL) reception. When receiving / transmitting is associated with a first beam and / or a first set of beams, if the first SFI indicates a symbol as DL and the frequency resource for configured reception is not within the first frequency resource, the UE cancels the symbol-configured (UL) transmission. When receiving / transmitting is associated with a first beam and / or a first set of beams, if the first SFI indicates a symbol as DL and the frequency resource for configured transmission is not within the first frequency resource, the UE performs a symbol-configured (UL) transmission.When receiving / transmitting is associated with a first beam and / or a first set of beams, if the first SFI indicates a symbol as UL and the frequency resource for scheduled reception is within the first frequency resource, the UE does not expect to schedule reception on symbol (DL). When receiving / transmitting is associated with a first beam and / or a first set of beams, if the first SFI indicates a symbol as UL and the frequency resource for scheduled reception is not within the first frequency resource, the UE schedules reception on symbol (DL). When receiving / transmitting is associated with a first beam and / or a first set of beams, if the first SFI indicates a symbol as UL and the frequency resource for scheduled reception is not within the first frequency resource, the UE does not expect to schedule transmission on symbol (UL). When reception / transmission is associated with a first beam and / or a first set of beams, if reception / transmission is associated with a first beam and / or a first set of beams, and if / when the first SFI indicates a symbol as DL and the frequency resource for scheduled transmission is not within the first frequency resource, the UE schedules (UL) transmission on the symbol. The UE receives an indication of a second frequency resource for the first beam and / or the first set of beams. The UE receives a second SFI for the first beam and / or the first set of beams. The second frequency resource is associated with the second SFI. The UE processes reception / transmission of its frequency resources within the second frequency resource based on the second SFI. When reception / transmission is associated with a first beam and / or a first set of beams, if / when the second SFI indicates a symbol as UL and the frequency resource for configured reception is within the second frequency resource, the UE cancels configured (DL) reception on the symbol. When receiving / transmitting is associated with the first beam and / or the first set of beams, if the second SFI indicates the symbol as DL and the frequency resource configured for transmission is within the second frequency resource, the UE cancels the configured (UL) transmission on the symbol. When receiving / transmitting is associated with the first beam and / or the first set of beams, if the second SFI indicates the symbol as UL and the frequency resource scheduled for transmission is within the second frequency resource, the UE does not expect scheduled (DL) reception on the symbol. When receiving / transmitting is associated with the first beam and / or the first set of beams, if the second SFI indicates the symbol as UL and the frequency resource scheduled for transmission is within the second frequency resource, the UE does not expect scheduled (UL) reception on the symbol. The UE receives a third SFI from the base station for the second set of beams and / or the second set of beams.The third SFI may be identical to the first SFI. The third SFI may be identical to the second SFI. When reception / transmission is associated with the second beam and / or the second set of beams, if reception / transmission is associated with the second beam and / or the second set of beams, and if / when the third SFI indicates the symbol as DL, the UE cancels the configurable (UL) transmission on the symbol. When reception / transmission is associated with the second beam and / or the second set of beams, if reception / transmission is associated with the second beam and / or the second set of beams, and if / when the third SFI indicates the symbol as DL, the UE performs the configurable (UL) transmission on the symbol. When reception / transmission is associated with the second beam and / or the second set of beams, if / when the third SFI indicates the symbol as UL, the UE does not expect to schedule (DL) reception on the symbol. When receiving / transmitting is associated with a second beam and / or a second set of beams, the UE schedules reception on the symbol (DL) if / when the third SFI indicates the symbol as UL. When receiving / transmitting is associated with a second beam and / or a second set of beams, the UE does not intend to schedule transmission on the symbol (UL). When receiving / transmitting is associated with a second beam and / or a second set of beams, the UE schedules transmission on the symbol (UL) if / when the first SFI indicates the symbol as DL.

[0200] In another embodiment, the base station transmits an indication to the UE of whether duplex enhancement applies to a beam (or beam set). The indication may indicate which beams and / or beam sets the duplex enhancement applies to. The indication may also indicate which beams and / or beam sets the duplex enhancement does not apply to. The indication may indicate that the duplex enhancement applies to a first beam and / or a first set of beams. The indication may also indicate that the duplex enhancement applies to a second beam and / or a second set of beams. A first frequency resource is associated with a first SFI. For the second beam and / or the second set of beams, the base station does not transmit an indication of the first frequency resource to the UE. The base station transmits a first SFI for the first beam and / or the first set of beams to the UE. When reception / transmission is associated with the first beam and / or the first set of beams, or if reception / transmission is associated with the first beam and / or the first set of beams, then the base station processes reception / transmission of its frequency resources within the first frequency resource based on the first SFI. When a receive / transmit is associated with a first beam and / or a first set of beams, the base station does not process a receive / transmit whose frequency resource is not within the first frequency resource based on the first SFI. When a receive / transmit is associated with a first beam and / or a first set of beams, the base station processes a receive / transmit whose frequency resource is not within the first frequency resource as if no first SFI is indicated. When a receive / transmit is associated with a first beam and / or a first set of beams, if the first SFI indicates a symbol as UL and the configured received frequency resource is within the first frequency resource, the base station cancels the configured (DL) transmission on the symbol. When a receive / transmit is associated with a first beam and / or a first set of beams, if the first SFI indicates a symbol as UL and the frequency resource for configured reception is not within the first frequency resource, the base station performs a symbol-configured (DL) transmission. When a receive / transmit is associated with a first beam and / or a first set of beams, if the first SFI indicates a symbol as DL and the frequency resource for configured transmission is within the first frequency resource, the base station cancels symbol-configured (UL) reception. When a receive / transmit is associated with a first beam and / or a first set of beams, if the first SFI indicates a symbol as DL and the frequency resource for configured transmission is not within the first frequency resource, the base station performs symbol-configured (UL) reception.When a receive / transmit is associated with a first beam and / or a first set of beams, if the receive / transmit is associated with a first beam and / or a first set of beams, and if / when the first SFI indicates a symbol as UL and the frequency resource for scheduled reception is within the first frequency resource, the base station does not intend to schedule (DL) transmission on the symbol. When a receive / transmit is associated with a first beam and / or a first set of beams, if / when the first SFI indicates a symbol as UL and the frequency resource for scheduled reception is not within the first frequency resource, the base station schedules (DL) transmission on the symbol. When a receive / transmit is associated with a first beam and / or a first set of beams, if / when the first SFI indicates a symbol as DL and the frequency resource for scheduled reception is within the first frequency resource, the base station does not perform scheduled (UL) reception on the symbol. When reception / transmission is associated with a first beam and / or a first set of beams, if reception / transmission is associated with a first beam and / or a first set of beams, and if / when the first SFI indicates a symbol as DL and the frequency resource for scheduled transmission is not within the first frequency resource, the base station performs scheduled (UL) reception on the symbol. The base station transmits an indication of a second frequency resource for the first beam and / or the first set of beams to the UE. The base station transmits a second SFI for the first beam and / or the first set of beams. The second frequency resource is associated with the second SFI. The UE processes reception / transmission of its frequency resources within the second frequency resource based on the second SFI. When reception / transmission is associated with a first beam and / or a first set of beams, if / when the second SFI indicates a symbol as UL and the frequency resource for configured reception is within the second frequency resource, the base station cancels scheduled (DL) transmission on the symbol. When a reception / transmission is associated with the first beam and / or the first set of beams, if the reception / transmission is associated with the first beam and / or the first set of beams, and if / when the second SFI indicates the symbol as DL and the frequency resource configured for transmission is within the second frequency resource, the base station cancels configured (UL) reception on the symbol. When a reception / transmission is associated with the first beam and / or the first set of beams, if / when the second SFI indicates the symbol as UL and the frequency resource scheduled for transmission is within the second frequency resource, the base station does not schedule (DL) transmission on the symbol. When a reception / transmission is associated with the first beam and / or the first set of beams, if / when the second SFI indicates the symbol as DL and the frequency resource scheduled for transmission is within the second frequency resource, the base station does not schedule (UL) reception on the symbol. The base station transmits a third SFI for the second set of beams to the UE.The third SFI may be identical to the first SFI. The third SFI may be identical to the second SFI. When reception / transmission is associated with the second beam and / or the second set of beams, if reception / transmission is associated with the second beam and / or the second set of beams, and if / when the third SFI indicates the symbol as DL, the base station cancels configurable (UL) reception on the symbol. When reception / transmission is associated with the second beam and / or the second set of beams, if reception / transmission is associated with the second beam and / or the second set of beams, and if / when the third SFI indicates the symbol as DL, the base station performs configurable (UL) reception on the symbol.

[0226] Problems and solutions:

[0227] Duplex enhancement schemes can affect how the UE handles DL reception or UL transmission. For example, for a regular DL symbol (e.g., without duplex enhancement), the UE will not perform UL transmission on such a symbol, such as eliminating configured UL transmission on the symbol, or UL transmission scheduled by DCI that is not expected on the symbol (the NW will not perform such scheduling and / or the UE will treat such scheduling as an error). Similar restrictions on DL reception can be applied to regular UL symbols. The indicated transmission direction applies to all / all frequency resources of the bandwidth portion / serving cell. However, such restrictions may no longer be effective when a symbol under duplex enhancement can support more than one transmission direction, such as both DL and UL. For example, the UE may be able to perform UL transmission on a symbol indicated as DL. Whether duplex enhancement is applicable may depend on the isolation between DL transmission and UL reception on the base station side. For example, when performing DL transmission on one gNB beam and UL reception on another gNB beam, if the two gNB beams have good isolation, such as when there is little mutual interference, DL transmission and UL reception can be performed simultaneously on the same symbol. In other words, duplex enhancement is applicable. On the other hand, when the two gNB beams do not have good isolation, for example, when there is more mutual interference, DL transmission and UL reception may not be performed simultaneously on the same symbol. In this case, duplex enhancement is not applicable. In other words, collision handling may differ depending on whether duplex enhancement is applied to different beams or not. Given the multiple beams between DL and UL, some adjustments to the collision handling rules will require further consideration.

[0228] The concept of this invention is to determine whether / how to apply conflict handling based on different situations and / or circumstances and / or factors. The UE determines a first conflict handling rule in a first situation. The UE determines a second conflict handling rule in a second situation. For example, the UE determines the transmission direction (or SFI) of a symbol based on different situations and / or circumstances and / or factors, according to different transmission directions (or SFIs) indicated for the symbol. For example, the UE determines whether / how to handle reception / transmission on a symbol based on different situations and / or circumstances and / or factors (based on the transmission direction (or SFI)) of the symbol. An example of a situation / factor may be a beam associated with transmission / reception. The UE determines whether / how to handle reception / transmission on a symbol based on the transmission direction (or SFI) of the symbol using the beam associated with reception / transmission. The UE determines which conflict handling rule applies to reception / transmission based on the beam associated with reception / transmission. The UE determines whether the first conflict handling rule or the second conflict handling rule applies for reception / transmission based on the beam associated with reception / transmission. The UE determines whether the old conflict handling rule or the new conflict handling rule applies based on the beam associated with reception / transmission. The rule applies to all time / frequency resources (e.g., all indicated subsequent resources). The rule applies to a subset of time resources (e.g., certain symbols or time slots). The rule applies to a subset of time resources (e.g., certain PRB / bandwidth parts (BWP)). The rule can be used to enable duplex enhancement.

[0229] Another example of a situation / factor could be the type of SFI (or the signaling indicating the SFI, such as a common RRC signal, a dedicated RRC signal, DCI format 2_0, scheduling DCI, etc.). The UE determines whether / how to process reception / transmission on a symbol based on the type of SFI (based on the direction of symbol transmission (or SFI)). The UE determines which conflict handling rules apply based on the type of SFI (e.g., the SFI involved in the conflict handling rules). The UE determines whether a first conflict handling rule or a second conflict handling rule applies based on the type of SFI (e.g., the SFI involved in the conflict handling rules). The UE determines whether an old conflict handling rule or a new conflict handling rule applies based on the type of SFI (e.g., the SFI involved in the conflict handling rules). For example, the UE applies the first / old conflict handling rule for an SFI indicated by a common RRC signal. The UE applies the second / new conflict handling rule for an SFI indicated by a dedicated RRC signal. The UE applies a conflict handling rule for an SFI indicated by a common RRC signal. The UE does not apply a conflict handling rule for an SFI indicated by a dedicated RRC signal. The UE applies a first conflict handling rule to SFIs indicated by RRC signals. The UE applies a second conflict handling rule to SFIs indicated by scheduling DCI or DCI format 2_0. The UE applies conflict handling rules to SFIs indicated by RRC signals. The UE does not apply conflict handling rules to SFIs indicated by scheduling DCI or DCI format 2_0. An example could be: the UE considers symbols in a time slot indicated as downlink by tdd-UL-DL-ConfigurationCommon as usable for reception (but not for transmission), and symbols in a time slot indicated as uplink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated as usable for transmission (but not for reception). The UE considers symbols in a time slot indicated as downlink by tdd-UL-DL-ConfigurationDedicated as usable for transmission, and symbols in a time slot indicated as uplink by tdd-UL-DL-ConfigurationDedicated as usable for reception.Another example is: For a set of symbols in a time slot that is indicated to the UE as downlink by tdd-UL-DL-ConfigurationCommon, when PUSCH, PUCCH, PRACH, or SRS overlaps with the symbol set of the time slot (even partially), the UE does not transmit the Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), Physical Random Access Channel (PRACH), or Sounding Reference Signal (SRS). For a set of symbols in a time slot that is indicated to the UE as downlink by tdd-UL-DL-ConfigurationDedicated, when PUSCH, PUCCH, PRACH, or SRS overlaps with the symbol set of the time slot (even partially), the UE transmits PUSCH, PUCCH, PRACH, or SRS. Another example of a situation / factor could be the type of reception / transmission (e.g., DL reception, UL transmission, configured DL reception, DL reception scheduled by DCI, configured UL transmission, UL transmission scheduled by DCI). The UE determines whether / how to process reception / transmission on a symbol based on the type of reception / transmission (depending on the transmission direction (or SFI) of the symbol). The UE determines which conflict handling rules apply to the reception transmission based on the type of reception / transmission. The UE determines whether a first conflict handling rule or a second conflict handling rule applies based on the type of reception / transmission. The UE determines whether an old conflict handling rule or a new conflict handling rule applies based on the type of reception / transmission. For example, the UE applies the first / old conflict handling rule for (DL) reception. The UE applies the second / new conflict handling rule for UL transmission. The UE applies conflict handling rules for (DL) reception. The UE does not apply conflict handling rules for (DL) reception. The UE applies the first / old conflict handling rule for configured (UL) transmission. The UE applies the second / new conflict handling rule for (UL) transmission scheduled by DCI. The UE applies conflict handling rules for configured (UL) transmission. The UE does not apply conflict handling rules for (UL) transports scheduled by DCI.An example could be: For a set of symbols in a time slot that is indicated to the UE as uplink by tdd-UL-DL-ConfigurationCommon, when the PDCCH, PDSCH, or CSI-RS overlaps with the symbol set of the time slot (even partially), the UE does not receive the Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), or Channel State Information Reference Signal (CSI-RS). For a set of symbols in a time slot that is indicated to the UE as downlink by tdd-UL-DL-ConfigurationCommon, when the PUSCH, PUCCH, PRACH, or SRS overlaps with the symbol set of the time slot (even partially), the UE transmits the PUSCH, PUCCH, PRACH, or SRS. Another example: For a set of symbols in a time slot that is indicated to the UE as downlink by tdd-UL-DL-ConfigurationCommon, the UE does not transmit PUSCH, PUCCH, PRACH, or SRS when PUSCH, PUCCH, PRACH, or SRS overlaps with the time slot's symbol set (even if partially), where PUSCH, PUCCH, PRACH, or SRS is configured to be transmitted. For a set of symbols in a time slot that is indicated to the UE as downlink by tdd-UL-DL-ConfigurationCommon, the UE does not transmit PUSCH, PUCCH, PRACH, or SRS when PUSCH, PUCCH, PRACH, or SRS overlaps with the time slot's symbol set (even if partially), where PUSCH, PUCCH, PRACH, or SRS is scheduled by DCI.

For example, a first conflict handling rule for a first frequency resource of a symbol is indicated to the UE, and a second conflict handling rule for a second resource of the symbol is indicated to the UE. If / when a frequency resource transmitted via a configured UL or a scheduled UL is within the first frequency resource, the UE executes the first conflict handling rule on the symbol or treats the scheduled UL transmission on the symbol as an error. If / when a frequency resource transmitted via a configured UL or a scheduled UL is within the second frequency resource, the UE executes the second conflict handling rule on the symbol. In another instance, the direction of the first conflict handling rule is associated with the first frequency resource. The first conflict handling rule is not associated with the second frequency resource. The UE performs corresponding actions for reception / transmission within the first frequency resource based on the first conflict handling rule. The UE does not perform corresponding actions for reception / transmission within the second frequency resource based on the first conflict handling rule. For example, the UE is instructed to apply the conflict handling rule to the first frequency resource of the symbol. The UE is instructed not to apply the conflict handling rule to the second frequency resource of the symbol. If / when the frequency resource transmitted via a configured UL or a scheduled UL is within the first frequency resource, the UE will apply the conflict handling rule. If / when the frequency resource transmitted via a configured UL or a scheduled UL is within the second frequency resource, the UE will not apply the conflict handling rule. If / when the frequency resource transmitted via a configured UL or a scheduled UL is within the second frequency resource, the UE will execute the second conflict handling rule.

[0338] The transmission direction on a symbol can be associated with a frequency resource. In one example, a first transmission direction is associated with a first frequency resource. A second transmission direction is associated with a second frequency resource. The UE performs corresponding actions for reception / transmission within the first frequency resource based on the first transmission direction. The UE performs corresponding actions for reception / transmission within the second frequency resource based on the second transmission direction. For example, the UE is instructed to perform a DL for the first frequency resource for the symbol, and a UL for the second resource for the symbol. If / when the frequency resource for which a configured UL transmission or a scheduled UL transmission is performed is within the first frequency resource, the UE will cancel the configured UL transmission on the symbol or treat the scheduled UL transmission on the symbol as an error. If / when the frequency resource for which a configured UL transmission or a scheduled UL transmission is performed is within the second frequency resource, the UE will perform a configured UL transmission or a scheduled UL transmission on the symbol. In another example, the first transmission direction is associated with a first frequency resource. The first transmission direction is not associated with a second frequency resource. The UE performs corresponding actions for reception / transmission within the first frequency resource based on the first transmission direction. The UE does not perform corresponding actions for reception / transmission within the second frequency resource based on the first transmission direction. For example, the UE is instructed to perform a DL for a first frequency resource for a symbol. The UE is instructed that the DL does not apply to a second frequency resource for the symbol. If / when the frequency resource transmitted via configured UL or scheduled UL is within the first frequency resource, the UE will cancel the configured UL transmission on the symbol or treat the scheduled UL transmission on the symbol as an error. If / when the frequency resource transmitted via configured UL or scheduled UL is within the second frequency resource, the UE behaves as if no DL was instructed for the symbol transmitted via configured UL or scheduled UL. If / when the frequency resource transmitted via configured UL or scheduled UL is within the second frequency resource, the UE will perform the configured UL transmission or scheduled UL transmission on that symbol.

[0339] The association between conflict handling rules and beams can be fixed or predefined. The association between conflict handling rules and beams can be indicated from the base station to the UE. This association can be configured via RRC signaling and / or indicated via MAC CE. The association can be indicated via DCI. DCI can be periodically monitored. DCI indicates that the association lasts for a certain period. When the association changes, DCI updates the association. The association can be indicated together with SFI. The association can be indicated separately from SFI. For example, the first SFI-RNTI and / or the first position of the SFI field can be associated with the first beam and / or the first set of beams. The second SFI-RNTI and / or the second position of the SFI field can be associated with the second beam and / or the second set of beams. The SFI indicated by the DCI associated with the first SFI-RNTI and / or the first position of the SFI field can be associated with the first beam and / or the first set of beams. The SFI indicated by the DCI associated with the second SFI-RNTI and / or the second position of the SFI field can be associated with the second beam and / or the second set of beams. The bitmap associated with the SFI can be used for the beam associated with the SFI.
