Description

Method, device and system for wireless communication

Background

The Specific Absorption Rate (SAR) is an index parameter for measuring the intensity of electromagnetic radiation of a terminal to a human body, and the terminal has strict index requirements on the SAR value in the standard and cannot exceed the limit value. Generally, the higher the terminal transmit power, the higher the SAR value. High power terminals (power >23dBm) therefore have higher SAR values than ordinary power terminals (power 23 dBm).

At present, for a New Radio (NR) of a fifth Generation mobile communication technology (5-Generation, 5G), in order to avoid the problem that the SAR of a high-power terminal exceeds the standard, the terminal needs to report the uplink timeslot occupation ratio supported by the terminal under the high-power condition. When the actual uplink timeslot proportion exceeds the capacity of the terminal, the power level of the high-power terminal is backed off to the normal power.

However, the terminal adopting the power backoff mode may cause a decrease in uplink coverage, and may even cause an uplink failure, which affects user experience.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

Fig. 1 is a schematic diagram of an application scenario of an embodiment of the present application.

As shown in fig. 1, communication system 100 may include a terminal device 110 and a network device 120. Network device 120 may communicate with terminal device 110 over the air. Multi-service transport is supported between terminal device 110 and network device 120.

It should be understood that the embodiment of the present invention is illustrated only by way of example in the communication system 100, but the embodiment of the present invention is not limited thereto. That is to say, the technical solution of the embodiment of the present invention can be applied to various communication systems, for example: a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), a Long Term Evolution (Long Term Evolution, LTE) System, a Time Division Duplex (TDD) System, a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, a New Radio (NR), a future 5G System, or the like. In addition, the technical solution of the embodiment of the present application may be applied to various communication systems based on non-orthogonal Multiple Access technologies, for example, a Sparse Code Multiple Access (SCMA) system, a Low Density Signature (LDS) system, and the like, and certainly, the SCMA system and the LDS system may also be called other names in the communication field; further, the technical solution of the embodiment of the present application may be applied to a Multi-Carrier transmission system using a non-Orthogonal multiple access technology, for example, an Orthogonal Frequency Division Multiplexing (OFDM) using a non-Orthogonal multiple access technology, a Filter Bank Multi-Carrier (FBMC), a General Frequency Division Multiplexing (GFDM), a Filtered Orthogonal Frequency Division Multiplexing (F-OFDM) system, and the like.

Taking a 5G system as an example, the technical scheme of the embodiment of the present application may be applied to a Long Term Evolution (LTE) coverage of a wide area and an islanding coverage mode of NR. Moreover, a large amount of LTE is deployed below 6GHz, and the spectrum below 6GHz available for 5G is rare. NR must therefore be studied for spectrum applications above 6GHz, with limited high band coverage and fast signal fading. Meanwhile, in order to protect the early LTE investment of a mobile operator, a work mode of tight connection (light interworking) between LTE and NR is provided.

The main application scenarios of 5G include: enhanced Mobile Ultra wide band (eMBB), Low-Latency and high-reliability Communication (URLLC), and massive machine type Communication (mMTC). Among them, the eMBB aims at users to obtain multimedia contents, services and data, and its demand is rapidly increasing. As the eMBB may be deployed in different scenarios. For example, indoor, urban, rural, etc. have relatively large differences in capabilities and needs, so that they cannot be analyzed in general and can be combined with detailed analysis of specific deployment scenarios. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.

In addition, since the complete 5G NR coverage is difficult to obtain, the network coverage of the embodiment of the present invention may adopt a Long Term Evolution (LTE) coverage of a wide area and an islanding coverage mode of NR. Meanwhile, in order to protect the mobile operator from LTE investment in the early stage, a tight connection (light interworking) working mode between LTE and NR may be further adopted.

In communication system 100 shown in fig. 1, network device 120 may be an access network device that communicates with terminal device 110. An access network device may provide communication coverage for a particular geographic area and may communicate with terminal devices 110 (e.g., UEs) located within the coverage area.

For example, the Access network device may be a Base Transceiver Station (BTS) in a Global System for Mobile communications (GSM) System or a Code Division Multiple Access (CDMA) System, a Base Station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA) System, or an evolved Base Station (evolved Node B, eNB, or eNodeB) in a Long Term Evolution (Long Term Evolution, LTE) System.

Optionally, the Access Network device may also be a Next Generation Radio Access Network (NG RAN), or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or the Access Network device may be a relay station, an Access point, a vehicle-mounted device, a wearable device, or a Network device in a Public Land Mobile Network (PLMN) that has not yet evolved, and the like.

The terminal device 110 may be any terminal device, and the terminal device 110 may communicate with one or more Core networks (Core networks) through a Radio Access Network (RAN), and may also be referred to as an Access terminal, a User Equipment (UE), a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment. For example, it may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device having a Wireless communication function, a computing device or other processing device connected to a Wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network, and the like.

It should be understood that the terms "system" and "network" are often used interchangeably herein.

Fig. 2 shows a schematic flow diagram of a method 200 of wireless communication according to an embodiment of the application, which method 200 may be performed interactively by a terminal device and a network device. The terminal device shown in fig. 2 may be a terminal device as shown in fig. 1, and the network device shown in fig. 2 may be an access network device as shown in fig. 1. The method 200 includes some or all of the following:

as shown in fig. 2, the method 200 includes:

s210, the terminal equipment determines the uplink time ratio in the target time window.

And S220, the terminal equipment determines whether to discard the uplink data in the target time window according to the uplink time ratio in the target time window.

In short, the terminal device may determine whether the uplink data in the target time window needs to be actively discarded by determining the uplink time ratio in the target time window.

It should be understood that the target time window in the embodiment of the present invention is used to indicate a time period with a certain length in the time domain, and the target time window may be understood as a specific time period, and may also be understood as a window moving forward in the time domain with a specific step size, that is, the target time window is a dynamic time period. For example, the target time window may include a plurality of time cells. The particular step size is one or more time units. Wherein each time unit of the plurality of time units may be a transmission unit in a time domain for transmitting data. For example, the time unit includes, but is not limited to, at least one of: slots, subframes, and radio frames.

Optionally, the time unit is 5ms, 10ms or 15ms in length.

Optionally, the terminal device may determine the uplink time ratio in the target time window in a cyclic manner.

Optionally, the terminal device may cyclically determine the uplink time ratio in the target time window based on a specific step size.

Optionally, the specific step size is a preset step size, or the specific step size is a step size configured by the network device.

Fig. 3 is a schematic block diagram of an embodiment of the present invention in which the target time window is a dynamic window that moves forward in time with a specific step size.

Specifically, as shown in fig. 3, the target time window is a first time window at a first time, the target time window is a second time window at a second time after the first time, the first time window includes a first time unit t1 to an nth time unit tn, the second time window includes a second time unit t2 to an n +1 th time unit t (n +1), and the second time window is separated from the first time window by a specific step.

In actual operation, when the target time unit is in the first time window, the terminal device first determines the uplink time ratio in the first time window, and then, when the target time window moves forward by a certain step (as shown in the first time unit t1) to the position of the second time window, determines the uplink time ratio in the second time window. The uplink time occupancy in the target time window may be a proportion of time units used for transmitting uplink data in the target time window occupying all time units in the target time window.

A specific implementation of triggering S210 (determining the uplink time ratio in the target time window) is described below with reference to a specific embodiment:

in the embodiment of the present invention, the terminal device may determine the uplink time ratio in the target time window when starting up, or may determine the uplink time ratio in the target time window after determining that a certain condition is satisfied. The embodiment of the present invention is not particularly limited thereto.

For example, after the terminal device enters the connected state, the uplink time ratio in the target time window is determined.

For another example, when the terminal device determines that the uplink transmission power of the terminal device is greater than or equal to the first threshold, the uplink time ratio in the first time is determined. Optionally, the first threshold is a maximum uplink transmission power of the terminal device.

Optionally, the method 200 illustrated in fig. 2 further includes:

s230, the terminal device determines to discard the uplink data in the target time window.

Optionally, when the terminal device determines that the uplink time occupying ratio in the target time window is greater than or equal to a second threshold, discarding part or all of the uplink data in the target time window.

Optionally, before the terminal device determines that the uplink time ratio in the target time window is greater than or equal to the second threshold, the terminal device determines the second threshold.

Optionally, the terminal device determines the second threshold according to an electromagnetic wave absorption ratio SAR of the terminal device and/or an uplink transmission power of the terminal device.

Optionally, the method 200 illustrated in fig. 2 further includes:

s240, the terminal device sends notification information to the network device.

And S250, the network equipment determines the reason for not receiving the uplink signal sent by the terminal equipment according to the notification information.

The notification information is used to notify the network device that the actual uplink time ratio of the terminal device has exceeded the uplink time ratio allowed by the terminal device.

In short, the network device receives a notification that the actual uplink time ratio of the terminal device sent by the terminal device has exceeded the allowed uplink time ratio of the terminal device, and the network device determines the reason why the uplink signal sent by the terminal device is not received.

Specifically, the terminal device discards the uplink data transmission scheduled by the network, the network device will not receive the acknowledgement/non-acknowledgement (ACK/NACK) feedback information corresponding to the uplink symbol, and the network device has two possible interpretations, i.e. the symbol is lost or the actual uplink time fraction of the terminal device exceeds its allowed uplink time fraction, e.g. the maximum uplink time fraction (maxuplinkdtycycle). The information reported by the terminal equipment assists the network equipment to judge the reason of the uplink transmission signal loss of the terminal equipment.

Optionally, the method 200 illustrated in fig. 2 further includes:

s260, the network device modulates the uplink scheduling policy of the terminal device based on the notification information.

Specifically, after the network device determines that the actual uplink time occupancy of the terminal device exceeds the allowed uplink time occupancy, the network device modulates the uplink scheduling policy of the terminal device. For example, uplink scheduling for the terminal device is reduced.
