Technical Field

The present application relates to the field of communications, and in particular, to a communication method and a communication device.

Generally, in a communication device, different inherent dc biases exist for different modulator devices.

At present, in the communication process between a terminal device and a network device, when the terminal device receives a message from the network device, a strong local oscillator leakage exists at a position of a direct current carrier corresponding to a receiving end of the terminal device, which affects the reception of a subcarrier at the position, so that the terminal device has a certain effect on demodulation performance during downlink demodulation, and normal operation of the terminal device is affected.

Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), tablet computers (pads), and computers with wireless transceiving functions. A wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile station), a Mobile Station (MS), a remote station (remote station), an Access Point (AP), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), a Subscriber Station (SS), a user terminal device (CPE), a terminal (terminal), a User Equipment (UE), a Mobile Terminal (MT), etc. The terminal device may also be a wearable device and a next generation communication system, for example, a terminal device in a 5G communication system or a terminal device in a Public Land Mobile Network (PLMN) for future evolution, etc.

(2) A network device: may be a device in a wireless network, for example, a network device may be a Radio Access Network (RAN) node (or device) that accesses a terminal device to the wireless network, which may also be referred to as a base station. Currently, some examples of RAN equipment are: a new generation base station (gbodeb), a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., a home evolved Node B or a home Node B, HNB), a Base Band Unit (BBU), or a wireless fidelity (Wi-Fi) Access Point (AP) in a 5G communication system. In addition, in one network configuration, the network device may include a Centralized Unit (CU) node, or a Distributed Unit (DU) node, or a RAN device including a CU node and a DU node.

The network device can send configuration information (for example, carried in a scheduling message and/or an indication message) to the terminal device, and the terminal device further performs network configuration according to the configuration information, so that network configuration between the network device and the terminal device is aligned; or, the network configuration between the network device and the terminal device is aligned through the network configuration preset in the network device and the network configuration preset in the terminal device. In particular, "alignment" refers to the fact that when an interactive message exists between a network device and a terminal device, the two devices are consistent in understanding the carrier frequency of interactive messaging, the determination of the type of interactive message, the meaning of the field information carried in the interactive message, or other configurations of the interactive message.

Furthermore, the network device may be other means for providing wireless communication functionality for the terminal device, where possible. The embodiments of the present application do not limit the specific technologies and the specific device forms used by the network devices. For convenience of description, the embodiments of the present application are not limited.

(3) Resource Element (RE) is defined as one symbol in time domain and one subcarrier in frequency domain, which is the minimum unit of the physical layer. Illustratively, 1 OFDM or SC-FDMA symbol is occupied in the time domain and 1 subcarrier is occupied in the frequency domain.

Resource Block (RB) refers to a specific physical resource used in the physical layer to actually transmit data and signaling information of a higher layer. Taking the LTE communication system as an example, 100 RBs correspond to a system configuration of a 20 megahertz (MHz) band. For example, an RB may be 14 symbols in the time domain and 12 consecutive subcarriers in the frequency domain, and in a typical scenario, the relationship between RBs and REs may be: RB-12 × 14 RE.

In addition, a plurality of RBs may form a resource block group (RB group, RBG), and taking a 100M bandwidth typical scenario as an example, the relationship between the RBG and the RB may be: RBG 16 RB.

(4) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a alone, A and B together, and B alone, wherein A and B may be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, "at least one of A, B, and C" includes A, B, C, AB, AC, BC, or ABC. And, unless specifically stated otherwise, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing between a plurality of objects, and do not limit the order, sequence, priority, or importance of the plurality of objects.

The present application may be applied to a Long Term Evolution (LTE) system, a New Radio (NR) system, or another communication system, where the communication system includes a network device and a terminal device, the network device is used as a configuration information sending entity, and the terminal device is used as a configuration information receiving entity. Specifically, a presentity in the communication system sends configuration information to another entity and sends data to another entity or receives data sent by another entity; and the other entity receives the configuration information and sends data to the configuration information sending entity or receives the data sent by the configuration information sending entity according to the configuration information. The present application may be applied to a terminal device in a connected state or an activated state (ACTIVE), and may also be applied to a terminal device in an unconnected state (INACTIVE) or an IDLE state (IDLE).

As shown in fig. 1, the configuration information sending entity may be a network device, where the network device is illustrated by taking a Base Station (Base Station) as an example, and the configuration information receiving entity may be UE1-UE6, in this case, the Base Station and UE1-UE6 form a communication system, in the communication system, UE1-UE6 may send uplink data to the network device, and the network device needs to receive the uplink data sent by UE1-UE 6. Meanwhile, the network device may send configuration information to UE1-UE 6.

In addition, in fig. 1, the UEs 4-UE6 may also form a communication system, in this case, the configuration information sending entity and the receiving entity may both be UEs, where the UE5 serves as a network device, i.e., the configuration information sending entity; the UE4 and the UE6 serve as terminal devices, i.e., configuration information receiving entities. For example, in a car networking system, the UE5 sends configuration information to the UE4 and the UE6, respectively, and receives uplink data sent by the UE4 and the UE 6; accordingly, the UE4 and the UE6 receive the configuration information transmitted by the UE5 and transmit uplink data to the UE 5.

In a communication system, local oscillator leakage means that in a communication device (a terminal device or a network device), an up-conversion module inherently has a direct current offset, which is generated by a device of the up-conversion module, so that a center of a frequency spectrum has a bulge. Generally, in a communication device, different inherent dc biases exist for different modulator devices.

In the case of a terminal device or a network device, local oscillator leakage occurs at the corresponding transmitting end and receiving end, and the dc interference caused by the local oscillator leakage raises the background noise and affects the demodulation threshold of the terminal device, thereby affecting the peak value and the network performance of the terminal device. Taking a terminal device as an example, it can be obtained through data acquisition experiments that local oscillator leakage at a UE transmitting end and a UE receiving end of the terminal device may be above 20 Decibels (DB), an influence range of 20DB interference on a demodulation threshold is 1.3-3.5 DB, and if scheduling is actually performed to avoid an RBG at an influencing position, an order of a Modulation and Coding Scheme (MCS) is increased by 2-3.7 orders.

At present, a processing scheme is made for direct current component interference introduced to a base station uplink by local oscillator leakage of a terminal equipment transmitting end: the method comprises the steps that a terminal device reports local oscillator leakage information (UpditxDiretcurrentList) of a transmitting end of the terminal device to a base station through an air interface message, wherein the UpditxDiretcurrentList can contain a part of bandwidth (BWP, also called bandwidth part) and the position of local oscillator leakage, and after the base station takes the information reported by the terminal device, the base station side sets the corresponding RE to zero to eliminate the influence of the local oscillator leakage of the transmitting end of the terminal device on the uplink demodulation performance of the base station. However, in the scheme, the base station and the terminal equipment are cooperatively optimized for local oscillator leakage at the transmitting end of the terminal equipment, so that the influence is eliminated or minimized. However, the scheme does not solve the influence of local oscillator leakage at the receiving end of the terminal equipment.

In addition, in the implementation of the processing of the local oscillator leakage at the transmitting end of the terminal equipment, the base station estimates the local oscillator receiving influence position of the terminal equipment through a self algorithm, and then the base station staggers the local oscillator leakage position of the terminal equipment obtained by the base station through the algorithm through scheduling (RB/RBG) in layer 2(layer 2, L2) (for example, Media Access Control (MAC) in L2), so as to avoid the influence of the local oscillator leakage on the demodulation performance of the terminal equipment when the terminal equipment performs downlink demodulation. However, in this scheme, the base station determines that the local oscillation position of the receiving end of the terminal device is estimated according to its own algorithm on the base station side, which is only an evasive scheme. Firstly, the base station does not confirm the local oscillation point received by the terminal equipment completely and accurately, and the local oscillation point at the receiving end of the terminal equipment is related to devices used by the terminal equipment and the algorithm of the terminal equipment. Secondly, the scheme is that the base station acts unilaterally, joint optimization is not performed with the terminal equipment, the base station can only perform scheduling optimization of RB/RBG granularity, RE-level optimization cannot be achieved accurately, and the optimization effect is not optimal.

Similarly, for local oscillator leakage at a transmitting end of network equipment, a better evasion scheme does not exist at present, and downlink demodulation of terminal equipment is easily influenced.

In summary, how to reduce the influence of the local oscillator leakage at the receiving end of the terminal device on the demodulation performance of the terminal device, and how to reduce the influence of the local oscillator leakage at the transmitting end of the network device on the demodulation performance of the terminal device are technical problems to be solved urgently.

Therefore, the embodiment of the present application provides a communication method and apparatus, which are used for reducing the influence of local oscillator leakage information on demodulation performance and improving communication efficiency in a downlink demodulation process of a terminal device. The following describes implementations of embodiments of the present application from various perspectives, such as methods, apparatuses, and the like, with reference to the accompanying drawings.

Referring to fig. 2, a schematic diagram of a communication method according to an embodiment of the present application is shown, where the method includes the following steps.

S101, the terminal equipment sends first information to the network equipment.

In this embodiment, the terminal device sends the first information to the network device in step S101, and correspondingly, the network device receives the first information from the terminal device in step S101, where the first information is used to indicate that the local oscillator leakage information of the receiving end of the terminal device is present.

In one possible implementation, the first information includes at least one of:

In one possible implementation, the first information is carried in a radio resource control RRC message.

S102, the network equipment sends a first message to the terminal equipment according to the first information.

In this embodiment, the network device sends, in step S102, a first message to the terminal device according to the first information received in step S101, and correspondingly, the terminal device receives, in step S102, a first message sent from the network device according to the first information in step S101.

Specifically, the first message may be a Control Plane (CP) message, a User Plane (UP) message, or another message, which is not limited in this embodiment.

S103, the terminal device demodulates the first message from the network device according to the first information.

In this embodiment, the terminal device demodulates the first message received in step S102 according to the first information in step S101 in step S103.

In a possible implementation manner, the process that the terminal device demodulates the first message from the network device according to the first information in step S103 may specifically include:

the terminal device demodulates the first message from the network device and carried in the first resource block RB, where the first RB does not include the RB indicated by the receiving-end local oscillator leakage information.

Based on the above technical solution, when the first information used for indicating the receiving-end local oscillator leakage information of the terminal device indicates a certain RB, in a process of demodulating the first message from the network device, the first message demodulated by the terminal device may be specifically carried on a first resource block RB that does not include the RB indicated by the receiving-end local oscillator leakage information, so that the terminal device performs data demodulation at positions of other RBs besides the RB indicated by the first information, thereby improving demodulation performance of the terminal device.

In a possible implementation manner, the process of the terminal device demodulating the first message from the network device according to the first information in step S103 may specifically include:

In a possible implementation manner, after the terminal device sends the first information to the network device in step S101, the method may further include:

the terminal device does not demodulate a second message, which is from the network device and is carried on a second RE, where the second RE includes an RE indicated by the receiving-end local oscillator leakage information.

Optionally, the second RE may be included in the target RB, in this case, the method may further include:

In this embodiment, a terminal device first sends first information to a network device, where the first information is used to indicate local oscillation leakage information of a receiving end of the terminal device; then, the terminal device demodulates the first message from the network device according to the first information. The terminal equipment sends first information used for indicating receiving end local oscillator leakage information of the terminal equipment to the network equipment, and demodulates first information from the network equipment according to the first information. That is, after the network device sends the first message to the terminal device according to the first message, avoiding the influence of the local oscillation leakage information of the receiving end of the terminal device, the terminal device demodulates the first message according to the first message, so that the influence of the local oscillation leakage information of the receiving end of the terminal device on the demodulation performance can be reduced in the process of performing downlink demodulation on the first message by the terminal device, and the communication efficiency is improved.

Based on the embodiment shown in fig. 2, as an exemplary implementation process, taking a terminal device as a UE and a network device as a base station as an example, the communication method may specifically be implemented by the following steps:

step 1, when accessing, the UE reports local oscillator leakage information (e.g., BWPid, RE location index where local oscillator dc component is located) of its receiving end to the base station through an RRC air interface message (e.g., rrcreeconfiguration complete, RRCResumeComplete, etc.), and the base station performs the processing procedure of step 2 after obtaining the information.

And 2, after obtaining the local oscillator leakage information reported by the UE, the base station and the UE can perform collaborative optimization. The collaborative optimization scheme may have two as follows:

the first optimization mode is as follows: after the base station receives the information of local oscillator leakage at the transmitting end of the UE, L2 of the base station selects to avoid the RB or RBG where the local oscillator information reported by the terminal is located through scheduling resources, and the terminal has a position for receiving the local oscillator leakage and does not perform data scheduling, so that the terminal does not need to perform data demodulation at the resource position where the local oscillator leakage exists. The influence of the local oscillator leakage received by the terminal on the demodulation performance of the terminal is avoided in scheduling.

The second optimization mode is as follows: after the base station receives the information of local oscillator leakage of the UE transmitting terminal, mutually specifying: when the base station and the UE calculate the RE number of the RB containing the local oscillator leakage, the RE with the local oscillator leakage is deducted, and the TBSize of the two ends is ensured to be consistent. On the premise, the base station does not perform data mapping at the RE position with local oscillator leakage, and the UE does not perform data demodulation at the corresponding position. Therefore, the influence of local oscillator leakage at the receiving end of the UE on the demodulation performance of the UE is avoided.

Through the implementation process, if the local oscillator leakage exists at the receiving end of the terminal equipment, the terminal equipment reports the local oscillator leakage information of the receiving end of the terminal equipment to the base station through the air interface message, and after the network equipment takes the information reported by the terminal equipment, the network equipment and the terminal equipment perform collaborative optimization together, so that the influence of the local oscillator leakage at the receiving end of the terminal equipment on the demodulation performance of the terminal equipment side is eliminated or reduced to the minimum. Therefore, for the UE with local oscillator leakage at the receiving end, the signal to noise ratio can be improved, the demodulation threshold of the UE can be reduced, and the peak value and the network pulling test performance can be improved.

S203, the terminal device demodulates the first message from the network device according to the first information.

In this embodiment, the terminal device demodulates the first message received in step S202 according to the first information in step S201 in step S203.

In one possible implementation manner, the terminal device demodulating, according to the first information, the first message from the network device in step S203 includes:

In one possible implementation manner, the terminal device demodulating the first message from the network device according to the first information in step S203 includes:

the terminal device demodulates the first message, which is from the network device and is carried on the first resource unit RE, where the first RE does not include the RE indicated by the receiver local oscillator leakage information.

In a possible implementation manner, after the terminal device receives the first information from the network device in step S201, the method may further include:

Optionally, the second RE may be included in the target RB, and in this case, the method may further include:

That is to say, the network device may send the local oscillator leakage information of the downlink transmitting end of the network device to the terminal device, and perform systematic joint optimization with the terminal device.
