[0028] The technical features, structural characteristics, objectives, and effects of the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. Specifically, the terminology used in the embodiments of this disclosure is only used to describe the purpose of a particular embodiment and is not intended to limit the disclosure.

[0029] The technical solutions of this disclosure can be applied to various communication systems, such as Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Advanced Long Term Evolution (LTE-A), New Radio (NR), evolution systems of NR, LTE-based access to unlicensed spectrum (LTE-U), NR-based access to unlicensed spectrum (NR-U), Universal Mobile Telecommunications System (UMTS), and global interoperability for microwave access. Access (WiMAX) communication systems, wireless local area networks (WLAN), wireless fidelity (Wi-Fi), the future fifth generation (5G) system (also known as the new radio (NR) system), and other communication systems.

[0030] Optionally, the base station mentioned in this application embodiment can provide communication coverage for a specific geographical area and can communicate with user equipment (UE) located within that coverage area. Optionally, the base station can be a base transceiver station (BTS) in a gNB, GSM, or CDMA system, or a NodeB (NB) in a WCDMA system, or an evolved NodeB (eNB or eNodeB) in an LTE system, or a radio controller in a cloud radio access network (CRAN).

[0031] User equipment (UE) can refer to an access terminal, subscriber unit, subscriber station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user equipment. An access terminal can be a cellular wireless phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA), handheld device with wireless communication capabilities, computing device, other processing devices coupled to a wireless modem, in-vehicle equipment, wearable device, terminal equipment in future 5G networks, and terminal equipment in future evolved public land mobile networks (PLMNs), etc.

[0032] Optionally, the communication system in this application embodiment can be applied to unlicensed spectrum, wherein unlicensed spectrum can also be regarded as shared spectrum; or the communication system in this application embodiment can also be applied to licensed spectrum, wherein licensed spectrum can also be regarded as non-shared spectrum.

[0033] New Radio (NR) systems introduced both incoherent and coherent joint transmissions based on multiple transmitter / receiver points (TRPs). In incoherent joint transmission, multiple TRPs are connected via one or more backhaul links for coordination. Backhaul links can be ideal or non-ideal. In ideal backhaul communication, TRPs can exchange dynamic physical downlink shared channel (PDSCH) scheduling information with short delays; therefore, different TRPs can coordinate PDSCH transmissions in each PDSCH transmission. However, in non-ideal backhaul communication, information exchange between TRPs has undesirable delays; therefore, coordination between TRPs can only be semi-static or static.

[0034] In incoherent joint transmission, different TRPs use different physical downlink control channels (PDCCHs) to independently schedule PDSCH transmissions. Each TRP can send downlink control information (DCI) on the PDCCH to schedule a PDSCH transmission. PDSCHs from different TRPs can be scheduled in the same or different time slots. Two different PDSCH transmissions from different TRPs can completely or partially overlap in PDSCH resource allocation.

[0035] To support incoherent joint transmission based on multiple TRPs, the requesting user equipment (UE) receives PDCCHs from multiple TRPs, and then receives PDSCHs sent from multiple TRPs. For each PDSCH transmission, the UE can send a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) message back to the network. In multi-TRP transmissions, the UE can send HARQ-ACK messages for each PDSCH transmission back to the TRP that sent that PDSCH. The UE can also send HARQ-ACK messages for PDSCH transmissions sent from any TRP back to a specific TRP.

[0036] Figure 1A The example shown is an incoherent joint transmission based on multiple TRPs. The UE receives the PDSCH based on incoherent joint transmissions from two TRPs: TRP1 and TRP2. Figure 1A As shown, TRP1 sends a downlink control information (DCI) to schedule the transmission of PDSCH1 to the UE, and TRP2 sends a DCI to schedule the transmission of PDSCH2 to the UE. On the UE side, the UE receives and decodes the DCIs from both TRPs. Based on the DCI from TRP1, the UE receives and decodes PDSCH1, and based on the DCI from TRP2, the UE receives and decodes PDSCH2. Figure 1AIn the example shown, the UE reports HARQ-ACKs for PDSCH1 and PDSCH2 to TRP1 and TRP2 respectively. TRP1 and TRP2 use different control resource sets (CORESETs) and search spaces to send DCIs scheduling PDSCH transmissions to the UE. Therefore, the network can configure multiple CORESETs and search spaces. Each TRP can be associated with one or more CORESETs and associated search spaces. With such a configuration, the TRP will use the associated CORESET to send DCIs to schedule PDSCH transmissions to the UE. The UE can be requested to decode the DCI in the CORESET associated with any TRP to obtain PDSCH scheduling information.

[0037] Figure 1B Another example of multi-TRP transmission is shown. The UE receives the PDSCH based on incoherent joint transmissions from two TRPs: TRP1 and TRP2. For example... Figure 1B As shown, TRP1 sends a DCI to schedule the transmission of PDSCH1 to the UE, and TRP2 sends a DCI to schedule the transmission of PDSCH2 to the UE. On the UE side, the UE receives and decodes the DCIs from both TRPs. Based on the DCI from TRP1, the UE receives and decodes PDSCH1, and based on the DCI from TRP2, the UE receives and decodes PDSCH2. Figure 1B In the example shown, the UE reports HARQ-ACK to the TRP for both PDSCH1 and PDSCH2, which is consistent with... Figure 1A The HARQ-ACK reports shown in the example are different. Figure 1B The example shown requires an ideal return route between TRP1 and TRP2, while Figure 1A The example shown can be deployed in scenarios where the return route between TRP1 and TRP2 is ideal or non-ideal.

[0038] NR supports timing advance functionality for uplink transmissions, where base stations such as the gNB send specific commands to the UE to adjust its uplink (UL) transmissions so that they arrive at the gNB at the correct timing. This UL adjustment applies to Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), and Sounding Reference Signal (SRS) transmissions. Timing advance information is delivered to the UE in two ways. The first is through a Random Access Channel (RACH) response (RAR). The gNB can indicate a timing advance value to the UE in a RAR message. The second is through a Medium Access Control (MAC) control element (CE) command. The gNB can indicate a timing advance value in a MAC CE command and, upon receiving the MAC CE command, can request the UE to apply the indicated timing advance value.

[0039] NR / 5G systems support frequency range 2 (FR2) operation. In FR2, the NR system can be a multi-beam system, where the base station, such as the gNB, has multiple downlink transmit (Tx) beams available for downlink transmission, and the UE can have multiple receive (Rx) beams available for downlink transmission reception. For uplink transmission, the UE can have multiple Tx beams available for transmission, and the gNB has multiple uplink Rx beams available for uplink reception. To support proper communication, the gNB and UE can find the optimal pair of gNB Tx beams and UE Rx beams. NR introduces beam measurement and reporting within the channel state information (CSI) framework to support the selection of optimal Tx and Rx beams. NR also supports beam indication functionality for downlink reception and uplink transmission. The gNB can indicate information about the Tx beams of the Physical Downlink Control Channel (PDCCH) and Physical Downlink Shared Channel (PDSCH) to the UE to assist downlink reception on the UE side. The gNB can also indicate to the UE the Tx beam information of the Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH), and Sound Reference Signal (SRS) to instruct the UE on how to transmit PUSCH, PUCCH, and SRS.

[0040] NR / 5G systems implement beam indication functionality through TCI (Transmission Configuration Indicator) status signaling. The UE can initially be provided with a joint TCI status list or a DL TCI status list and a UL TCI status list. Each joint TCI status provides configuration information for Quasi-Cooperative Positioning (QCL) type D for downlink reception (where QCL type D provides spatial Rx parameters for downlink reception) and reference information for UL Tx spatial filters for uplink transmission. Each joint TCI status can be associated with a set of uplink power control parameters (including P0, α, closed-loop power control index, and path loss RS). Each DL TCI status provides configuration information for QCL type D for downlink reception. Each UL TCI status provides reference information for UL Tx spatial filters for uplink transmission, and each UL TCI status can also be associated with a set of uplink power control parameters (including P0, α, closed-loop index, and path loss reference signal (RS)).

[0041] The gNB can indicate the joint TCI status or a pair of DL TCI and UL TCI statuses to the UE via DCI signaling. When the UE receives downlink control information (DCI) signaling for TCI status indication, the UE sends an acknowledgment (ACK) to the gNB. Then, the ACK can be sent from at least the last symbol of the PUCCH or PUSCH carrying the ACK. beamAppTime The indicated TCI state is applied starting from the first time slot after the symbol. Based on the QCL typeD information in the indicated TCI state, the UE will derive the Rx beam for receiving PDCCH and PDSCH. Based on the UL Tx spatial filter information in the indicated TCI state, the UE will derive the Tx beam for transmitting PUSCH, PUCCH, and / or SRS. Based on the indicated TCI state, the UE will derive the uplink power control parameters and path loss RS, and then calculate the uplink transmit power for PUSCH, PUCCH, and / or SRS transmission.

[0042] To support the system in selecting the appropriate TCI state, the NR specification also supports beam measurement and reporting functions. The system can configure the UE to measure a set of reference signals, such as Channel State Information Reference Signal (CSI-RS) resources and / or SS / PBCH blocks, and can request the UE to report the measurement results to the system. The reported measurement results may include indicators of the selected CSI-RS resources or synchronization signal and physical broadcast channel (SS / PBCH) and the corresponding Layer 1 reference signal received power (L1-RSRP) or Layer 1 signal-to-interference-noise ratio (L1-SINR) measurement results.

[0043] A drawback of current beam measurement and reporting methods is the significant time-frequency resource overhead required for Channel State Information Reference Signals (CSI-RS) used for beam training. To support systems with a large number of transmit beams, substantial CSI-RS resources will be needed for beam management. This results in high resource overhead and also significant delays in beam measurement and reporting.

[0044] To overcome these and other challenges, some embodiments of this disclosure provide solutions for superimposed beam reference signals and beam measurements based on superimposed beam reference signals.
