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 13 August 2019, whose disclosure is incorporated herein by reference in its entirety.

[0002] (Technical field) This application relates to communications, for example, information transmission methods and devices, information reception methods and devices, communication nodes, and storage media. [Background technology]

[0003] Ultra-wideband high-frequency communication (i.e., millimeter-wave communication) is a significant development in mobile communications and is attracting the attention of international academic research institutions and industry. For example, the advantages of millimeter waves are becoming increasingly attractive with the vast number of accesses to increasingly congested spectral resources and physical networks. Standardization has been initiated by many standardization bodies, including the Institute of Electrical and Electronics Engineers (IEEE) and the Third Generation Partnership Project (3GPP®). For example, the 3GPP® standardization body considers high-frequency band communication to be a key innovation in new radio access technologies (new RATs) for fifth-generation (5G) mobile communications technology due to its significant advantage of wide bandwidth.

[0004] In the antenna weight training process (also known as precoding or beam), a high-frequency band transmitting terminal transmits a training pilot, and a receiving terminal receives the channel and performs channel estimation. The high-frequency band receiving terminal then needs to feed back channel state information to the training transmitting terminal, thereby allowing the transceiver to identify multiple groups of transceiver antenna weight pairs from a given set of transceiver antenna weight pairs, which can be used for multi-path data transmission to improve overall spectral efficiency.

[0005] In 5G communication systems, when considering maximum power exposure (MPE) to the human body, the required maximum transmit power backoff will differ from that in actual transmission terms due to different irradiation of the human body under different uplink beams. From a transmission perspective, the maximum power reduction (MPR) resulting from MPE needs to be as low as possible to achieve efficient transmission for the uplink. However, in practical systems, maximum power reduction under different beams cannot be effectively achieved from a base station scheduling perspective.

[0023] Embodiments of the present invention will be described in detail below, in conjunction with the drawings. It should be noted that, wherever there is no inconsistency, embodiments and features thereof can be combined 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 the maximum power reduction of a first communication node. The method may be performed by an information transmission device provided in 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 this application can be considered a method for feeding back power parameters and channel status information. From the perspective of scheduling by the base station, it is impossible to effectively achieve maximum power reduction under different beams, and maximum power reduction can only be detected by a first communication node such as a user equipment (UE). The user equipment passively reduces its transmission power, resulting in a significant degradation of uplink transmission performance. This 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 this invention, the effects of MPE (such as the first type of power parameter information) and the uplink beam index considering MPE (such as the uplink channel state information) are directly or indirectly fed back to the base station terminal through power parameters and channel state information that are fed back according to channel quality measurements and other measurement information (e.g., detection of human body direction by a camera) of the user equipment (UE). In other words, maximum power reduction is directly or indirectly fed back through the first type of power parameter information or uplink channel state information, effectively assisting the base station terminal's decision regarding subsequent uplink beam scheduling with respect to the uplink channel and reference signal, and greatly improving system performance.

[0027] The reference signal includes at least one of the following: Channel State Information Reference Signal (CSI-RS), Channel State Information Interference Measurement (CSI-IM) signal, Demodulation Reference Signal (DMRS), Downlink Demodulation Reference Signal (DL DMRS), Uplink Demodulation Reference Signal (UL DMRS), Channel Sounding Reference Signal (SRS), Phase Tracking Reference Signal (PT-RS), Uplink Phase Tracking Reference Signal (UL PT-RS), Downlink Phase Tracking Reference Signal (DL PT-RS), Random Access Channel (RACH) signal, Synchronization Signal (SS), Synchronization Signal Block (also referred to as SS block or SS / PBCH block), Primary Synchronization Signal (PSS), or Secondary Synchronization Signal (SSS).

[0028] A beam can be a resource (e.g., reference signal resource, spatial relationships, transmitting terminal spatial filter, receiving terminal spatial filter, transmitting terminal precoding, receiving terminal precoding, antenna port, antenna weight vector (AWV), and antenna weight matrix). For transmission, a beam can be associated with several time-frequency code resources, so a beam serial number can be replaced with a resource index (e.g., reference signal resource index). A beam can also be a transmission (transmit / receive) mode. Transmission modes can include spatial division multiplexing, frequency domain / time domain diversity, etc.

[0029] Furthermore, the base station terminal, i.e., the second communication node, implements a quasi-collocation (QCL) configuration for two reference signals, notifies a UE such as the first communication node, and can explain channel characteristic hypotheses. Parameters related to quasi-collocation 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 the received beam, average delay, and correlation between time-frequency channel responses (including phase information).

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

[0031] When determining the maximum transmission power P CMAX,c , the UE first needs to determine the upper and lower limits, and the value between the upper and lower limits is 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 the parameter is used to distinguish cells, and c refers to cell c. EMAX,c This indicates the maximum transmit power configured by the network side and is relevant to the network deployment plan. C,c This is set for the upper and lower sidebands and has a value of 1.5 dB or 0 dB. PowerClass This represents the maximum transmit power without considering the power deviation tolerance (hereinafter abbreviated as tolerance). Different power classes correspond to different values. ΔP PowerClass P is when the uplink / downlink ratio configuration of user equipment of the second type of power class (i.e., power class 2UE) is 0 or 6, i.e., when the uplink occupies more time. PowerClass This is a decrease in ΔP. PowerClass The value for ΔT is 3dB, while the values ​​for other uplink / downlink ratios are 0dB. IB,c This indicates an additional tolerance set for some cells c, which, depending on the configuration, is accompanied by a value of 0 dB or 0 dB to 0.9 dB. ProSe This is configured considering direct communication between users, T ProSe The value is either 0.1 dB or 0 dB.

[0034] The Maximum Power Reduction (MPR) parameter is set to account for higher-order modulation and coding schemes (MCS) and transmission bandwidth factors. Higher modulation orders result in more limited maximum transmit power, allowing for relatively lower maximum transmit power. The more resource blocks (RBs) actually allocated, the more limited the maximum transmit power, allowing for lower maximum transmit power.

[0035] Additional MPR (A-MPR) parameters are set to take into account the requirements of additional specific deployment scenarios. That is, the requirements for radio frequency transmission differ depending on the deployment scenario or the country and region. For most scenarios, the A-MPR value is between 1 dB and 5 dB, while in some scenarios, the value reaches 17 dB.

[0036] P-MPRc In other words, the maximum power reduction for power management refers to the maximum transmission power reduction, which is set considering factors such as electromagnetic energy absorption rate or interference reduction between multiple systems.

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

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

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

[0040] Typical beam reporting is for downlink transmission, where the downlink reference signal index is reported according to the reference signal received power (RSRP). However, for uplink transmission, if the uplink transmission beam corresponding to the reported downlink reference signal is directed towards a human body, the additional effect of power management maximum power reduction (P-MPR) must be considered. Therefore, the optimal downlink transmission beam combination is not necessarily the same as the uplink transmission beam combination. In addition, the effect of P-MPR is that the UE's transmit power is P c,max It only works when the P-MPR is reached and the uplink duty cycle exceeds the threshold. When P-MPR has no effect, the optimal downlink beam can be assumed to be the optimal uplink beam.

[0041] Figure 3 is a schematic diagram illustrating the panel-specific MPE effect according to the present invention. When the UE has multiple antenna groups, each antenna group corresponds to a different MPR. For example, the 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, and thereafter the MPR is very large; however, the sight of panel 2 (i.e., panel-2) of the UE does not face the human body, and thereafter the effect from MPR can be ignored under UE panel-2. The uplink transmission beam of panel 1 of the UE is UL The Tx beam is at UE panel-1. The uplink transmission beam at UE panel 2 is the UL Tx beam at UE panel-2. The first uplink is UL-link-1. The second uplink is UL-link-2. The uplink receive beam at the transmission receiving point (TRP) for panel 1 is the UL Rx beam at TRP subpanel 1. The uplink receive beam at the transmission receiving point (TRP) for panel 2 is the UL Rx beam at TRP subpanel 2.

[0042] As shown in Figure 1, the information transmission method provided by this application includes S110.

[0043] In S110, the reporting information is transmitted to the second communication node, and the reporting information includes at least one of the first type of power parameter information or uplink channel status information.

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

[0045] In this specification, the difference between “Type 1” and “Type 2” (which are the same with respect to power parameter information, antenna group information, and reference signal information (but not limited to them)) is that Type 1 information must 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, its scheduling and decision-making activities are affected. The relationships between Type 2 information may be configured or predetermined by the base station to the UE, rather than being reported to the base station terminal in the case of Type 1 information. In addition, Type 1 and Type 2 information may be the same or different. For example, Type 1 power parameter information may be power headroom, while Type 2 power parameter information may be maximum power reduction. For convenience of expression in this specification, Type 1 identification parameters are referred to as Type 1 information, and Type 2 identification parameters are referred to as Type 2 information. For example, the first type of information may include, but is not limited to, the first type of power parameter information, the first type of antenna group information, and the first type of reference signal information.

[0046] According to the information transmission method provided in this application, reporting information is transmitted to a second communication node. The reporting information includes at least one of a first type of power parameter information or uplink channel status information. In this way, the reporting information is effectively transmitted to the second communication node, which then schedules the first communication node to determine a maximum power reduction and thus reduce the maximum power exposure to the human body.

[0047] Based on the above embodiments, modified embodiments of the above embodiments are proposed, and it should be noted that, for the sake of brevity of explanation, only the differences from the above embodiments will be described in this specification.

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

[0049] The remaining energy value refers to (maximum exposure energy value - 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 a given window are configurable and can be configured, for example, by a second communication node. The window parameters include at least one of the following: window length, window period, window start point, or window time offset. The time unit is determined by the time unit in which the reporting information is located or the time unit of the physical uplink shared channel (PUSCH) to which the reporting information is associated.

[0050] Power headroom can be either actual power headroom or virtual power headroom. In one embodiment, virtual power headroom may also be referred to as power headroom based on a reference format.

[0051] Uplink duty cycle information, also referred to as the uplink duty cycle value or uplink duty cycle, represents the ratio of the accumulated uplink transmission duration within a given time range to the duration within that given time range.

[0052] Alert identification information includes information indicating whether power-related parameters or parameter fluctuations (such as maximum power reduction, remaining energy value, stored energy value, uplink duty cycle information, power headroom, or power backoff) trigger a threshold, information for enabling power parameter feedback (such as P-MPR), or MPE alert information.

[0053] In one embodiment, the uplink channel status information includes at least one of a first type of reference signal information, a first type of antenna group information, an uplink path loss value, pseudo-collocation information, pseudo-collocation beam information, or an uplink additional correction value.

[0055] In one embodiment, the reference signal information may be an uplink reference signal index or a downlink reference signal index. The reference signal information includes, but is not limited to, a first type of reference signal information and a second type of reference signal information.

Note that a beamset may include uplink beams or downlink beams. When a beamset includes downlink beams, the UE can use beam correspondence to drive the corresponding uplink transmit beam.

[0131] Table 1 shows the format of an uplink report relating to the present invention. An example of such a report is one that includes a first type of power parameter information and uplink channel status information. In an uplink report, that is, when the report information is transmitted, it includes power parameter information (i.e., the first type of power parameter information) and uplink channel status information. A correlation relationship exists between the power parameter information and the uplink channel status information. For example, the power parameter information is reference information (e.g., MPR value) and corresponds to an uplink reference signal or a downlink reference signal. In one embodiment, the MPR value under a given uplink beam or a given downlink beam is reported. [Table 1]

[0132] Power Headroom Report (PHR) is P cmax It is equal to the difference between and the required power. For actual PHRs, the required power is determined according to the actual transmission, taking into account the effects of the uplink beam. For virtual PHRs, the required power is determined based on pre-configured parameters. In order to actively report the effects of MPR or MPE, PHR reporting under optional uplink beam sets should be supported, and the PHR report should carry relevant information about the uplink beam.

[0133] Table 2 shows the power headroom parameter reporting format related to this application. [Table 2]

[0134] Referring to Table 2, Table 2 is the power headroom parameter reporting format relating to this application. P indicates whether backoff power is used (i.e., due to P-MPR). When P=1, it is indicated that backoff power is used, and P CMAX,c The field is output. V indicates whether a virtual PHR or an actual PHR is currently output. R represents a reserved field. The reference signal index or spatial relation index is V=1, indicating that when a virtual PHR is output, the PHR calculates the assumed uplink beam information.

[0135] In one embodiment, when an actual PHR is reported and the MPR value is above a threshold, the UE may still report a virtual PHR. In this way, a potentially low MPE-impact uplink beam may be provided to assist in base station scheduling.

[0136] Figure 3A is a configuration flowchart for virtual power headroom according to the present invention. Referring to Figure 3A, S1 and S2 are included.

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

[0138] S2, according to the PHR, reports the uplink spatial relation index, and one or more uplink spatial relation indices from a set of arbitrary values ​​and the power headroom and P corresponding to the uplink spatial relation index. cmax However, this refers to the fact that it 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 virtual PHR reporting is initiated, the UE terminal selects an uplink spatial relationship from among multiple uplink spatial relationships, such as uplink spatial relationship index 2, and therefore the value of the virtual PHR and P cmax The value can be calculated. For example, targeting the maximization of the PHR value, the uplink spatial relation index and its power control parameters with the maximum PHR value are reported.

[0140] Figure 3B is a schematic diagram of the conditions and method for triggering a power headroom report according to the present application. Within a given time window (e.g., within 1 second), after the uplink duty cycle information exceeds a threshold, the P-MPR begins to take effect and a PHR report is triggered. The PHR report is carried over 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 one embodiment, the potential SRI is an SRI indicated for PUSCH transmission on the downlink control information (DCI) field.

[0141] To detect low MPE-impacted uplink beams, in addition to reporting PHR values, the virtual PHR reporting format may include a reference signal (i.e., reference signal information) or an uplink power control parameter set. In one embodiment, the reference signal and uplink power control parameter set may be selected from alternative sets pre-configured by the base station.

[0142] A virtual PHR is triggered to report when the MPE's impact exceeds a threshold (e.g., P-MPR and uplink duty cycle information). 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 values). In one embodiment, once a reference signal is reported, the path loss value associated with the PHR value should be determined according to the reference signal.

[0143] Virtual PHRs include virtual PHRs related to PUSCH, virtual PHRs related to Physical Uplink Control Channels (PUCCH), or virtual PHRs related to SRS.

[0144] In exemplary embodiments, the present application further provides an information receiving method. The information receiving method is applied to a second communication node. The method may be performed by an information receiving device, which may be implemented by software and / or hardware and integrated on the second communication node. The method may be adapted to determine the maximum power reduction of the first communication node. The embodiments described above are referenced with respect to matters not yet covered in these embodiments and are not repeated herein.

[0145] Figure 4 is a flowchart of the information receiving method according to the present application. As shown in Figure 4, the information receiving method provided by the present application includes S210 and S220.

[0146] In S210, the reporting information transmitted by the first communication node is received, and the reporting information includes at least one of the first type of power parameter information or uplink channel status information.

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

[0148] Once the first communication node is scheduled, scheduling on the first communication node may be carried out according to the reported information in such a way as to reduce the impact of the first communication node on the human body. For example, a beam with minimum and maximum power reduction may be selected for communication.

[0149] Reporting information transmitted by a first communication node is received according to the information receiving method provided herein, the reporting information includes a first type of power parameter information or uplink channel status information, and the first communication node is scheduled. Based on the reporting information, the second communication node determines the maximum power reduction of the first communication node, and then, based on the reporting information, schedules the first communication node to reduce the maximum power exposure to the human body.
