Description

Technical Field

[0001] This disclosure relates to the field of communication systems, and more specifically, to wireless communication apparatus and methods. Background Technology

[0002] In existing positioning methods, positioning reference signals cannot be transmitted on the same time-frequency resources as other communication channels or reference signals. To enable user equipment (UE) to measure downlink (DL) positioning reference signals, the system must configure measurement gaps for positioning measurements. Within the time window configured for these measurement gaps, the UE does not receive any communication channels or reference signals; it can only receive and measure the positioning reference signal. This causes several serious problems for the entire system: normal data transmission must be paused when the UE receives the positioning reference signal, thus impairing system data throughput. It also increases the latency of normal data transmission, thereby reducing service performance.

[0003] Therefore, wireless communication devices and methods are needed. Summary of the Invention

[0029] The technical content, structural features, implementation objectives, and effects of the embodiments of this disclosure will be described in detail below 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 this disclosure.

[0030] The technical solutions of this disclosure can be applied to various communication systems, such as Global System for Mobile Communications (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), LTE Advanced Long Term Evolution (LTE-A), New Radio (NR), NR system evolution, LTE-based Unlicensed Spectrum Access (LTE-U), NR-based Unlicensed Spectrum Access (NR-U), Universal Mobile Telecommunications System (UMTS), Global Microwave Interconnection Access (WiMAX), Wireless Local Area Network (WLAN), Wi-Fi, future fifth-generation (5G) systems (also known as New Radio (NR) systems), or other communication systems.

[0031] 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 the coverage area. Optionally, the base station can be a base transceiver station (BTS) in a gNB, GSM, or CDMA system, a NodeB (NB) in a WCDMA system, an evolved Node B (eNB or eNodeB) in an LTE system, or a radio controller in a cloud radio access network (CRAN).

[0032] 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 device coupled with 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.

[0033] 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.

[0034] New Radio (NR) systems introduce both incoherent and coherent joint transmission based on multiple transmitter / receiver points (TRPs). In incoherent joint transmission, multiple TRPs are connected via one or more backhaul links for coordination. These 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 latency, allowing different TRPs to coordinate PDSCH transmissions for each transmission. However, in non-ideal backhaul communication, the information exchange between TRPs incurs undesirable latency; therefore, coordination between TRPs can only be semi-static or static.

[0035] In incoherent joint transmission, different TRPs use different Physical Downlink Control Channels (PDCCHs) to independently schedule PDSCH transmissions. Each TRP can send a Downlink Control Message (DCI) on the PDCCH to schedule one 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.

[0036] To support incoherent joint transmission based on multiple TRPs, the requesting user equipment (UE) is to receive PDCCHs from multiple TRPs, followed by PDSCHs sent by 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 by any TRP back to a specific TRP.

[0037] Figure 1A An example of incoherent joint transmission based on multiple TRPs is shown. The UE receives the PDSCH based on incoherent joint transmission from two TRPs (TRP1 and TRP2). Figure 1A As shown, TRP1 sends a downlink control message (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; 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 send DCIs scheduling PDSCH transmissions to the UE using different control resource sets (CORESETs) and search spaces. 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 this configuration, the TRP will send DCIs using the associated CORESETs to schedule PDSCH transmissions to the UE. The UE can be requested to decode the DCIs in the CORESETs associated with any TRP to obtain PDSCH scheduling information.

[0038] 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; 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 in the examples shown 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 between TRP1 and TRP2 is ideal or non-ideal.

[0039] Positioning technology is one of the core technologies of wireless communication and navigation systems. 5G NR systems support positioning technology. In 3GPP Release 16, the following positioning technology schemes are specified: Downlink (DL) Time Difference of Arrival (TDOA) method, Uplink (UL) TDOA method, Multiple Round Trip Time (RTT) method, DL Angle of Departure (AoD) method, UL Angle of Arrival (AoA) method, and Enhanced Cell Identification (E-CID) method.

[0040] In 3GPP NR, a downlink positioning reference signal (PRS) was introduced to support downlink positioning measurements, and a sounding reference signal (SRS) for positioning was introduced to support uplink positioning measurements. For example, NR Release 16 supports the following positioning measurements: downlink reference signal time difference (RSTD) based on DL PRS measurements, uplink relative time of arrival (RTOA) based on SRS for positioning measurements, UE receive transmission (Rx-Tx) time difference, gNB Rx-Tx time difference, DL PRS reference signal received power (RSRP), UL SRS RSRP, and UL AoA.

[0041] The NR-based positioning technology solution involves the following functional entities:

[0042] UE: The UE measures DL PRS resources sent from multiple different TRPs, or sends SRS resources for positioning.

[0043] Transmit / Receive Point (TRP): To determine the location of a UE, multiple TRPs are typically involved. Each TRP can send a DL PRS to the UE, or receive and measure the SRS sent by the UE for positioning.

[0044] Location server: It may be referred to as location management function (LMF).

[0045] Figure 1C An example of NR positioning based on DL measurements is shown. As illustrated, the basic process includes at least one of the following operations: The LMF coordinates DL PRS configuration with the TRPs. Each TRP sends DL PRS resources according to the configuration. The UE measures the DL PRS resources sent from multiple TRPs, and then measures the DL PRS RSRP and / or DL ​​RSTD. The UE reports the positioning measurement results to the LMF. Finally, the LMF calculates the UE's location based on the reported positioning measurement results. Specifically, in the DL-AoD method, the UE measures the path RSRP or RSRP of one or more DL RS resources and then reports the measurement results to the LMF. The LMF can determine a UE's departure angle relative to each TRP, and the LMF can then calculate the UE's location.

[0046] As specified in the NR, the UE can be configured with one or more DL PRS resource sets, and each DL PRS resource set can consist of one or more DL PRS resources. For each DL PRS resource set, the UE is provided with the following configuration parameters:

[0047] The dl-PRS (Periodicity and ResourceSetSlotOffset) defines the periodicity of DL PRS resources and sets their values. Each time slot ( Here, , respectively, correspond to dl-PRS-SubcarrierSpacing (dl-PRS-SubcarrierSpacing) of 15, 30, 60, and 120, and the time slot offset of the DLPRS resource set relative to SFN0 time slot 0. All DL PRS resources within a DL PRS resource set are configured with the same DL PRS resource periodicity.

[0048] The dl-PRS-MutingOption1 and dl-PRS-MutingOption2 define the time points at which DL PRS resource sets are expected not to send DL PRS resources. If dl-PRS-MutingOption1 is configured, each bit in the dl-PRS-MutingOption1 bitmap corresponds to a configurable number of consecutive instances of the DL PRS resource set provided by the higher-layer parameter dl-prs-MutingBitRepetitionFactor; where, for an instance indicated as muted, all downlink PRS resources within that resource set are muted. The bitmap length can be {2, 4, 6, 8, 16, 32} bits. If dl-PRS-MutingOption2 is configured, each bit in the bitmap of dl-PRS-MutingOption2 corresponds to a single repeating index of each DL PRS resource within each instance of nr-DL-PRS-ResourceSet, and the length of the bitmap is equal to the value of dl-PRS-ResourceRepetitionFactor.

[0049] NR-DL-PRS-SFN0-Offset defines the time offset of SFN0 slot 0 of the transmitting cell relative to SFN0 slot 0 of the reference cell.

[0050] The bandwidth of a DL PRS resource can lie outside the bandwidth of an active bandwidth portion (BWP), and the subcarrier spacing used by the DL PRS resource can also differ from the subcarrier spacing of the active BWP. Therefore, a UE needs a measurement gap to measure DL PRS resources. Measurement gaps used for positioning are configured via Radio Resource Control (RRC). When a UE needs to measure DL PRS resources but no measurement gap is available, the UE can request a measurement gap via RRC signaling.

[0051] There is also an uplink-based positioning method. A UE sends SRS for positioning to multiple TRPs in the uplink. Each TRP receives the SRS for positioning from the UE and obtains the corresponding measurement results, which can be arrival timing measurements (called RSTD), SRS RSRP measurements, or angle of arrival measurements. Subsequently, the TRP reports these measurement results to the LMF. The LMF can estimate the UE's position based on the uplink measurements reported from multiple TRPs.

[0052] In existing positioning methods, positioning reference signals cannot be transmitted on the same time-frequency resources as other communication channels or reference signals. To enable user equipment (UE) to measure downlink (DL) positioning reference signals, the system must configure measurement gaps for positioning measurements. Within the time window configured during these measurement gaps, the UE does not receive any communication channels or reference signals; it can only receive and measure the positioning reference signal. This causes several serious problems for the entire system. Normal data transmission must be paused when the UE receives the positioning reference signal, thus impairing system data throughput. It also increases the latency of normal data transmission, thereby reducing service performance.

[0053] To overcome these and other challenges, some embodiments of this disclosure provide several technical solutions for the transmission and measurement of superimposed positioning reference signals, as detailed below.

In some embodiments, if the at least one positioning reference signal transmitted in an overlay manner is not measured, or the at least one positioning reference signal does not overlap with the communication channel, the base station requests the UE to measure the at least one positioning reference signal within a measurement gap. In some embodiments, the base station requests the UE to use a positioning service level to determine whether to measure the at least one positioning reference signal transmitted in an overlay manner to obtain at least one positioning measurement result. In some embodiments, the base station is configured to transmit the PDCCH, PDSCH, and / or CSI-RS to the UE. In some embodiments, the base station indicates to the UE whether the at least one positioning reference signal is transmitted in an overlay manner along with the PDCCH, PDSCH, or CSI-RS.

[0070] Exemplary technical solutions:

[0071] In some embodiments, a configuration for a positioning reference signal can be provided to the UE, and the UE can be configured such that the positioning reference signal can be transmitted in a superimposed manner relative to other communication channels, including PDCCH and PDSCH, wherein the positioning reference signal can be transmitted on the same time-frequency resources as PDCCH and / or PDSCH. The UE can be configured to measure the positioning reference signal transmitted in a superimposed manner to obtain a positioning measurement result, such as the time difference of arrival of positioning reference signals at different TPs, the RSRP measurement of the positioning reference signal, the carrier phase measurement of the positioning reference signal, or the time of arrival measurement of the positioning reference signal. For measuring a positioning reference signal that supports superimposed transmission, the UE does not need to request a measurement gap, which is a time window in which no other channels or other reference signals are transmitted. For the positioning reference signal, when transmitted in a superimposed manner, a power scaling factor can be provided to the UE. The power scaling factor can be used to indicate the power offset between the positioning reference signal and PDCCH, PDSCH, and / or CSI-RS.

[0072] In some embodiments, in the first method, one or more positioning reference signals may be configured for the UE. For each positioning reference signal, a power scaling factor may be provided to the UE, which indicates the power offset between the positioning reference signal and the PDCCH, PDSCH, and / or CSI-RS when the positioning reference signal is transmitted in an overlay manner relative to the PDCCH, PDSCH, and / or CSI-RS.

[0073] In some embodiments, in the second method, one or more positioning reference signals may be configured for the UE. For each positioning reference signal, a first indicator may be provided to the UE, indicating whether the positioning reference signal is transmitted in a superimposed manner relative to the PDCCH, PDSCH, and / or CSI-RS. For each positioning reference signal, a second indicator may be provided to the UE, indicating whether the UE can measure the positioning reference signal when it is transmitted in a superimposed manner relative to the PDCCH, PDSCH, and / or CSI-RS.

[0074] In some examples, if the positioning reference signal is measurable when it is transmitted in an overlay manner, the UE can measure the positioning reference signal outside the measurement gap, and the UE does not need to request a measurement gap to measure the positioning reference signal.

[0075] In some examples, if the positioning reference signal cannot be measured when it is transmitted in an overlay manner, the UE should measure the positioning reference signal within the measurement gap, or measure the positioning reference signal when it does not overlap with the PDCCH, PDSCH and / or CSI-RS.

[0076] In some embodiments, in the third method, one or more positioning reference signals may be configured for the UE, and the UE may be configured to measure the positioning reference signals to obtain some positioning measurement results. The UE may be requested to obtain the measurement results based on whether the positioning reference signals are sent in an overlay manner.

[0077] In one example, the UE can be requested to obtain time-of-arrival related positioning measurements from positioning reference signals that have never been transmitted in an overlay manner.

[0078] In one example, the UE can be requested to obtain RSRP type measurements from a positioning reference signal that can be transmitted in an overlay manner or not.

[0079] In one example, the UE can be requested to obtain carrier phase measurements from a positioning reference signal that has never been transmitted in an overlay manner.

[0080] In one example, the UE may be requested to use the requested location service level to determine whether it can obtain measurement results from a location reference signal transmitted in an overlay manner. For example, if the positioning accuracy is below a certain threshold, the UE may be requested not to measure the location reference signal transmitted in an overlay manner. For example, if the location service latency is below a certain threshold, the UE may be requested to measure the location reference signal transmitted in an overlay manner.

[0081] In some embodiments, in the fourth method, one or more positioning reference signals can be configured for the UE, and the UE can be requested to measure the positioning reference signals and then report the positioning measurement results. The positioning measurement results can be: the time difference of arrival of different TPs or positioning reference signals, the RSRP measurement of the positioning reference signal, the angle of arrival of the positioning reference signal, the carrier phase measured from the positioning reference signal, and / or the time difference between the downlink arrival time and the uplink transmission time. For each reported positioning measurement result, the UE can be requested to report whether the reported positioning measurement result was obtained from a positioning reference signal transmitted in an overlay manner; in other words, whether the corresponding positioning reference signal overlaps with the PDCCH, PDSCH, and / or CSI-RS.

[0082] In one example, for each reported location measurement result, the UE can report the corresponding SIP_indicator, which indicates whether the corresponding location reference signal is transmitted in an overlay manner. An example value for SIP_indicator can be 0 or 1. For a reported location measurement result, SIP_indicator = 1 indicates that the location reference signal used to obtain the reported location measurement result is transmitted in an overlay manner; for a reported location measurement result, SIP_indicator = 0 indicates that the location reference signal used to obtain the reported location measurement result is not transmitted in an overlay manner.

[0083] In some embodiments, in one method, the UE may be configured to receive PDCCH, PDSCH, and / or CSI-RS. For each of PDCCH, PDSCH, and CSI-RS, the UE may be indicated whether a positioning reference signal is transmitted in an overlay manner along with PDCCH, PDSCH, or CSI-RS.

[0084] In one example, for the PDCCH, the UE can be instructed to transmit the positioning reference signal and the PDCCH in an overlay manner. The UE can also be provided with time-frequency resource allocation in the case of overlapping positioning reference signal and PDCCH, and / or power offset between the overlapping positioning reference signal and PDCCH.

[0085] In one example, for a PDSCH, the UE can be instructed to transmit the positioning reference signal and the PDSCH in an overlay manner. The UE can also be provided with time-frequency resource allocation for cases where the positioning reference signal and the PDSCH overlap, and / or power offset between the overlapping positioning reference signal and the PDSCH.

[0086] In one example, for CSI-RS, the UE can be instructed to transmit the positioning reference signal and the CSI-RS in an overlay manner. The UE can also be provided with time-frequency resource allocation and / or power offset between the overlapping positioning reference signal and the CSI-RS in cases where the positioning reference signal and the CSI-RS overlap.

[0087] In summary, in some embodiments, the proposed method can improve the spectral efficiency of the entire system by transmitting PDCCH, PDSCH and / or CSI-RS and positioning reference signals on the same time-frequency resources, while also reducing system transmission latency and positioning service latency.

[0088] Some embodiments offer the following commercial benefits: 1. Solving problems in the prior art and other issues. 2. Improving the overall system spectral efficiency. 3. Reducing system transmission latency. 4. Reducing location service latency. 5. Providing good communication performance. 6. Providing high reliability.
