Description

[Technical field]

[0001] This application claims priority to Chinese Patent Application No. 201910746227.3, filed with the China National Intellectual Property Administration (CNIPA) on August 13, 2019, the disclosure of which is incorporated herein by reference in its entirety.

[0002] (Technical field) The present application relates to the field of communications, e.g., information transmitting methods and devices, information receiving methods and devices, communication nodes, and storage media. [Background technology]

[0003] Ultra-wideband high-frequency bands (i.e., millimeter wave communication) have become an important trend for mobile communication development and have attracted the attention of international academic research institutes and industries. For example, the advantages of millimeter wave are now becoming more and more attractive with the increasingly congested spectrum resources and the vast number of accesses to physical networks. Standardization has been initiated in many standardization organizations, such as the Institute of Electrical and Electronics Engineers (IEEE) and the 3rd Generation Partnership Project (3GPP®). For example, in the 3GPP® standardization organization, high-frequency band communication has become an important innovation point of the new radio access technology (new RAT) of the fifth generation (5G) mobile communication technology due to its great advantages of wide bandwidth.

[0004] In the antenna weight training process (also called precoding or beam), the high frequency band transmitting terminal transmits training pilots, and the receiving terminal receives the channel and performs channel estimation. Then, the high frequency band receiving terminal needs to feed back channel state information to the training transmitting terminal, so that the transceiver can find multiple groups of transceiver antenna weight pairs from arbitrary transceiver antenna weight pairs, which can be used for multi-path data transmission to improve overall spectrum efficiency.

[0005] In a 5G communication system, when considering the maximum power exposure (MPE) to the human body, the required maximum transmission power back-off will be different from the perspective of actual transmission due to different irradiation to the human body under different uplink beams. From the perspective of transmission, the maximum power reduction (MPR) brought by the MPE needs to be as low as possible to achieve efficient transmission for the uplink. However, in a practical system, the maximum power reduction under different beams cannot be effectively realized from the perspective of scheduling by the base station.

[0023] The embodiments of the present application are described in detail below in conjunction with the drawings. It should be noted that, if not contradictory, the embodiments of the present application and the features therein can be combined with each other in any manner.

[0024] In an exemplary embodiment, Figure 1 is a flowchart of an information transmission method according to the present application. The method may be applied when a second communication node (such as a base station) determines a maximum power reduction of a first communication node. The method may be executed by an information transmission device provided by the present application, which may be implemented by software and / or hardware and integrated on the first communication node.

[0025] The information transmission method provided by the present application can be considered as a method of feeding back power parameters and channel state information. From the viewpoint of scheduling by the base station, it is impossible to effectively realize the maximum power reduction under different beams, and the maximum power reduction can only be detected by the first communication node, such as a user equipment (UE). The user equipment passively reduces the transmission power of the user equipment, resulting in significant degradation in the performance of uplink transmission. The present application provides feedback of power parameters and channel quality regarding maximum power exposure (MPE), thereby assisting the base station terminal, i.e., the second communication node, in implementing effective scheduling to avoid impacts on the human body.

[0026] In the present application, through power parameters and channel state information fed back according to channel quality measurements and other measurement information (e.g., detection of the direction of a human body by a camera) of a user equipment (UE), the influence of MPE (such as a first type of power parameter information) and an index of an uplink beam taking MPE into consideration (such as uplink channel state information) are directly or indirectly fed back to a base station terminal, i.e., through the first type of power parameter information or uplink channel state information, the maximum power reduction is directly or indirectly fed back, which effectively assists the base station terminal's decision regarding subsequent uplink beam scheduling for the uplink channel and reference signal, and greatly improves system performance.

[0027] The reference signal includes at least one of a channel state information reference signal (CSI-RS), a channel state information interference measurement (CSI-IM) signal, a demodulation reference signal (DMRS), a downlink demodulation reference signal (DL DMRS), an uplink demodulation reference signal (UL DMRS), a channel sounding reference signal (SRS), a phase tracking reference signal (PT-RS), an uplink phase tracking reference signal (UL PT-RS), a downlink phase tracking reference signal (DL PT-RS), a random access channel (RACH) signal, a synchronization signal (SS), a synchronization signal block (also referred to as an SS block or SS / PBCH block), a primary synchronization signal (PSS), or a secondary synchronization signal (SSS).

[0028] A beam can be a resource (e.g., a reference signal resource, a spatial relationship, a transmitting terminal spatial filter, a receiving terminal spatial filter, a transmitting terminal precoding, a receiving terminal precoding, an antenna port, an antenna weight vector (AWV), and an antenna weight matrix). Since a beam can be associated with some time-frequency code resources for transmission, a beam serial number can be replaced with a resource index (e.g., a reference signal resource index). A beam can also be a transmission (transmit / receive) modality. The transmission modality can include space-division multiplexing, frequency domain / time domain diversity, etc.

[0029] Furthermore, the base station terminal, i.e., the second communication node, may implement a quasi-co-location (QCL) configuration for the two reference signals and inform the UE, e.g., the first communication node, of the channel characteristic hypothesis. The parameters related to the quasi-co-location include at least one of Doppler spread, Doppler shift, delay spread, average delay, average gain, and spatial parameters. The spatial parameters may include spatial reception parameters such as angle of arrival, spatial correlation of received beams, average delay, and correlation between time-frequency channel responses (including phase information).

[0030] The MPE problem is explained below. The maximum permissible power refers to the upper limit of the transmission power over a certain transmission time, also called the actual maximum transmission power, P CMAX The maximum allowed power is generally determined according to UE capabilities, base station deployment, frequency band information, and other factors.

[0031] Maximum transmit power P CMAX,c When determining , the UE first needs to determine the upper and lower bounds, and the values ​​between the upper and lower bounds are defined as follows: P CMAX_L,c ≦P CMAX,c ≦P CMAX_H,c

[0032] The upper and lower limits are defined as follows: P CMAX_L,c =MIN{P EMAX,c - T C,c ,(P PowerClass -ΔP PowerClass )-MAX(MPR c +A-MPR c +ΔT IB,c + T C,c + T ProSe ,P-MPR c )} P CMAX_H,c =MIN{P EMAX,c ,P PowerClass -ΔP PowerClass}

[0033] The subscript c indicates that a parameter is used to distinguish cells, and c denotes cell c. EMAX,c T denotes the maximum transmit power configured by the network side and is related to the network deployment plan. C,c is set for the upper and lower sidebands and has a value of 1.5 dB or 0 dB. PowerClass denotes the maximum transmission power without considering the power deviation tolerance (hereinafter, "tolerance" for short). Different power classes correspond to different values. ΔP PowerClass is the P when the uplink / downlink ratio configuration of the second type of power class user equipment (i.e., power class 2 UE) is 0 or 6, i.e., the uplink occupies more time PowerClass The decrease in ΔP PowerClass The value of ΔT is 3 dB and the values ​​for other uplink / downlink ratios are 0 dB. IB,c denotes the additional tolerance set for some cell c, with values ​​of 0 dB or between 0 dB and 0.9 dB, depending on the configuration. ProSe is set considering direct communication between users, and T ProSe The value is 0.1 dB or 0 dB.

[0034] The maximum power reduction (MPR) parameter is set to take into account higher order modulation and coding schemes (MCS) and transmission bandwidth factors. The higher the modulation order, the more limited the maximum transmission power is, and the less maximum transmission power is allowed. The more resource blocks (RBs) are actually allocated, the more limited the maximum transmission power is, and the less maximum transmission power is allowed.

[0035] The additional MPR (A-MPR) parameter is set taking into consideration the requirements for additional specific deployment scenarios, i.e., the requirements for radio frequency transmission are different in different deployment scenarios or different countries and regions. For most scenarios, the value of A-MPR is 1 dB to 5 dB, and for some scenarios, the value reaches 17 dB.

[0036] P-MPRc , that is, the power management maximum power reduction indicates the maximum transmission power reduction, which is set taking into consideration factors such as electromagnetic energy absorption rate or interference reduction between multiple systems.

[0037] In this application, the MPR can be any one of the MPR, A-MPR, or P-MPR, taking into account higher order MCS and transmission bandwidth factors.

[0038] FIG. 2 is a structural diagram of a hybrid precoding transceiver according to the present application. Hybrid precoding is a hybrid analog-digital beamforming. The transmitting terminal and receiving terminal of the system are composed of multiple antenna units and multiple radio frequency links. Each radio frequency link is connected to an antenna array unit (partial connection scenario is not excluded), and each antenna unit has a digital keying phase shifter. The high frequency band system implements the beamforming of the analog terminal by loading different amounts of phase shifts to the signals of the antenna units. Specifically, in the hybrid beamforming transceiver, there are multiple radio frequency signal streams. Each signal stream is loaded with a precoding antenna weight vector (AWV) through a digital keying phase shifter, and is transmitted from the multiple antenna units to the high frequency band physical propagation channel. In the receiving terminal, the radio frequency signal streams received by the multiple antenna units are weighted and combined into a single signal stream, and after radio frequency demodulation is performed in the receiving terminal, the receiver finally obtains multiple received signal streams, which are sampled and received by a digital baseband.

[0039] The MPR should be a beam-specific or antenna group-specific (panel-specific) MPR.

[0040] A typical beam report is a beam report for downlink transmission, i.e., the downlink reference signal index is reported according to the reference signal received power (RSRP). However, for uplink transmission, when the uplink transmission beam corresponding to the reported downlink reference signal is directed toward the human body, the effect of additional power management maximum power reduction (P-MPR) needs to be considered. Therefore, the optimal downlink transmission beam combination is not necessarily the uplink transmission beam combination. In addition, the effect of P-MPR may occur when the transmission power of the UE is P c,max and the uplink duty cycle exceeds the threshold. When P-MPR is ineffective, the optimal downlink beam may be assumed to be the optimal uplink beam.

[0041] FIG. 3 is a schematic diagram illustrating the influence of panel-specific MPE according to the present application. When a UE has multiple antenna groups, each antenna group corresponds to a different MPR. For example, a UE includes two antenna panels for uplink transmission (i.e., two panels for UL transmission). The sight of panel 1 (i.e., panel-1) faces the human body, so the MPR is very large; however, the sight of panel 2 (i.e., panel-2) of the UE does not face the human body, so the influence from MPR can be ignored under UE panel-2. The uplink transmission beam of panel 1 of the UE is oriented toward the UL The uplink transmit beam for the UE, Panel 2 is UL Tx beam@UE Panel-2. The first uplink is UL-link-1. The second uplink is UL-link-2. The uplink receive beam for the transmit receive point (TRP) for Panel 1 is UL Rx beam@TRP sub-panel 1. The uplink receive beam for the transmit receive point (TRP) for Panel 2 is UL Rx beam@TRP sub-panel 2.

[0042] As shown in FIG. 1, the information transmitting method provided by the present application includes S110.

[0043] At S110, report information is transmitted to a second communication node, where the report information includes at least one of a first type of power parameter information or uplink channel condition information.

[0044] The information transmission method may be referred to as a parameter feedback method in this application. That is, the first type of power parameter information is transmitted to the second communication node, or the uplink channel state information is transmitted to the second communication node, or the first type of power parameter information and the uplink channel state information are transmitted to the second communication node. At least one of the first type of power parameter information or the uplink channel state information is transmitted to the second communication node. In this way, the maximum power reduction is directly or indirectly fed back to the second communication node, whereby the second communication node schedules the first communication node to reduce the influence of the first communication node on the human body. The report information may be information reported to the second communication node. The report information may include at least one of the first type of power parameter information or the uplink channel state information.

[0045] It should be noted that in this specification, the difference between the "first type" and the "second type" (which are the same in terms of (not limited to) power parameter information, antenna group information, and reference signal information) is that the first type of information needs to be carried in a report (i.e., included in the report information) and reported by the UE (i.e., the first communication node) to the base station terminal (i.e., the second communication node). After the base station terminal receives the report, the scheduling and decision-making activities of the base station terminal are affected. The association relationship between the second type of information may be configured or pre-determined by the base station for the UE, rather than being reported to the base station terminal in the first type of information. In addition, the first type of information and the second type of information may be the same or different. For example, the first type of power parameter information may be power headroom, while the second type of power parameter information may be maximum power reduction. For convenience of expression in this specification, the parameter of the first type of identification is referred to as the first type of information, and the parameter of the second type of identification is referred to as the second type of information. For example, the first type of information includes, but is not limited to, a first type of power parameter information, a first type of antenna group information, and a first type of reference signal information.

[0046] According to an information transmission method provided by the present application, report information is transmitted to a second communication node. The report information includes at least one of a first type of power parameter information or uplink channel state information. In this way, the report information is effectively transmitted to the second communication node, whereby the second communication node determines a maximum power reduction and thus schedules the first communication node to reduce the maximum power exposure to the human body.

[0047] Based on the above embodiment, a variant embodiment of the above embodiment is proposed, and it should be noted that in this specification, for the sake of simplicity of explanation, only the differences from the above embodiment will be described in the variant embodiment.

[0048] In an embodiment, the first type of power parameter information includes at least one of a maximum power reduction, a remaining energy value, an accumulated energy value, uplink duty cycle information, alert identification information, a power backoff, or a power headroom.

[0049] The remaining energy value refers to the maximum exposure energy value - the energy value accumulated during a window or first time unit. The accumulated energy value is the energy accumulated during a given window or a given time unit. The parameters of the given window are configurable, e.g., configured by the second communication node. The parameters of the window include at least one of a window length, a window period, a start point of the window, or a time offset of the window. The time unit is determined by the time unit in which the report information is located or the time unit of the physical uplink shared channel (PUSCH) with which the report information is associated.

[0050] The power headroom may be a real power headroom or a virtual power headroom. In an embodiment, the virtual power headroom may also be referred to as a power headroom based on a reference format.

[0131] Table 1 is the format of the uplink report related to the present application. Report information including a first type of power parameter information and uplink channel state information is taken as an example. In the uplink report, that is, when the report information is transmitted, the power parameter information (i.e., the first type of power parameter information) and the uplink channel state information are included. An association relationship exists between the power parameter information and the uplink channel state information. For example, the power parameter information is reference information (e.g., a value of MPR) and corresponds to an uplink reference signal or a downlink reference signal. In an embodiment, the value of MPR under a given uplink beam or a given downlink beam is reported. [Table 1]

[0132] Power Headroom Reporting (PHR) is cmax and the required power. For real PHR, the required power is determined according to the actual transmission, taking into account the influence of the uplink beam. For virtual PHR, the required power is determined based on pre-configured parameters. In order to actively report the influence of MPR or MPE, PHR reporting under any uplink beam set needs to be supported, and the PHR report needs to carry related information about the uplink beam.

[0133] Table 2 is the power headroom parameter reporting format pertaining to this application. [Table 2]

[0134] Referring to Table 2, Table 2 is the power headroom parameter report format related to this application. P indicates whether backoff power is used (i.e., due to P-MPR). When P=1, it indicates that backoff power is used, and P CMAX,c The fields are output. V indicates whether a virtual PHR or a real PHR is currently being output. R represents a reserved field. The reference signal index or spatial relationship index is V=1, indicating that when a virtual PHR is being output, the PHR will calculate the assumed uplink beam information.

[0135] In one embodiment, when the actual PHR is reported and the value of the MPR is equal to or greater than the threshold, the UE may still report a virtual PHR. In this manner, a potential low MPE impact uplink beam may be provided to assist base station scheduling.

[0136] 3A is a configuration flow chart for virtual power headroom according to the present application. Referring to FIG. 3A, S1 and S2 are included.

[0137] S1 indicates that uplink power control parameter sets corresponding to different uplink spatial relationships are configured by radio resource control (RRC) signaling.

[0138] S2 reports an uplink spatial relationship index according to the PHR, and determines one or more uplink spatial relationship indexes from the optional set and a power headroom and P corresponding to the uplink spatial relationship index. cmax This refers to what is reported.

[0139] The base station terminal configures multiple uplink spatial relationships through RRC signaling, and each uplink spatial relationship is associated with an uplink power control parameter set. When the virtual PHR reporting is initiated, the UE terminal selects an uplink spatial relationship from the multiple uplink spatial relationships, such as uplink spatial relationship index 2, and thus determines the value of the virtual PHR and P cmax For example, with the target of maximizing the PHR value, the uplink spatial relationship index with the maximum PHR value and its power control parameter are reported.

[0140] 3B is a schematic diagram of a condition and a method for triggering a power headroom report according to the present application. After the uplink duty cycle information exceeds a threshold within a given time window (e.g., within 1 second), the P-MPR starts to take effect and a PHR report is triggered. The PHR report is carried on PUSCH-#n. The PHR report carries the actual PHR, and in addition, a virtual PHR report under one or more potential SRS resource indications (SRIs) is provided. In an embodiment, the potential SRI is the SRI indicated for the PUSCH transmission on the downlink control information (DCI) field.

[0141] In order to detect low MPE-impacting uplink beams, in addition to reporting the PHR value, the virtual PHR report format may include a reference signal (i.e., reference signal information) or an uplink power control parameter set. In an embodiment, the reference signal and the uplink power control parameter set may be selected from an alternative set preconfigured by the base station.

[0142] When the influence of the MPE exceeds a threshold (e.g., P-MPR and uplink duty cycle information), a virtual PHR is triggered to be reported. The user should report the PHR value and the reference signal or uplink power control parameter set associated with the PHR value, with the goal of maximizing the PHR value (or minimizing the P-MPR and path loss value). In an embodiment, when the reference signal is reported, the path loss value associated with the PHR value needs to be determined according to the reference signal.

[0143] The virtual PHR includes a virtual PHR for a PUSCH, a virtual PHR for a physical uplink control channel (PUCCH), or a virtual PHR for an SRS.

[0144] In an exemplary embodiment, the present application further provides an information receiving method. The information receiving method is applied to a second communication node. The method can be executed by an information receiving device, and the information receiving device can be implemented by software and / or hardware and integrated on the second communication node. The method can be adapted to determine the maximum power reduction of the first communication node. For contents that are not yet comprehensive in this embodiment, reference is made to the above embodiment, which will not be repeated in this specification.

[0146] At S210, report information transmitted by a first communication node is received, where the report information includes at least one of a first type of power parameter information or uplink channel condition information.

[0147] At S220, the first communication node is scheduled.

[0148] When the first communication node is scheduled, the scheduling on the first communication node may be performed according to the report information to reduce the impact of the first communication node on the human body, for example, a beam with the lowest maximum power reduction is selected for communication.

[0149] According to the information receiving method provided by the present application, report information transmitted by a first communication node is received, the report information includes a first type of power parameter information or uplink channel state information, and the first communication node is scheduled. A second communication node determines a maximum power reduction of the first communication node based on the report information, and then schedules the first communication node based on the report information to reduce the maximum power exposure to a human body.
