FIG. 1 is an exemplary flow chart of a communication parameter adjustment method according to an embodiment of the present invention, which can be performed by a network device or a terminal device, and as shown in FIG. includes S110 to S130.

At S110, the first device establishes communication with the second device based on the initial settings of the communication parameters.

At S120, the first device adjusts settings of one or more communication parameters in the communication parameters based on network conditions and/or service conditions in the communication.

In S130, the first device transmits communication parameter adjustment instruction information to the second device, and the communication parameter adjustment instruction information is used by the first device to set one or more communication parameters in the communication parameters. is used to indicate the result of adjustment.

Therefore, the communication parameter adjustment method in the embodiment of the present invention, the terminal device as both the network device or the communication can dynamically adjust the communication parameter setting based on the network state and/or the service state, which can improve the performance and applicability of wireless communication systems.

In addition, in the embodiments of the present invention, the first device may be a network device, in which case the second device is a terminal device, or the first device is a terminal device, in which case the second device is another terminal device.

Optionally, as shown in FIG. 2, the method further includes S140.

At S140, the first device receives the processing power indication information transmitted by the second device, the processing power indication information is used by the second device using the same kind of parameters with different settings to determine the Used to indicate that it is possible to communicate with the first device.

In other words, the first device adjusts the communication parameters based on the network and/or service conditions in the communication only if the second device determines that it can communicate with it using the same type of parameters with different settings. . That is, in an embodiment of the present invention, different communication parameters can be used within time-frequency resource blocks allocated to different users in the same subcarrier/cell, so that the first device and the second device The transmitters and receivers of the above need to be capable of processing multiple types of communication parameters at the same time, and the device types can be divided according to the device's ability to simultaneously process different parameters.

In addition, the second device can report the ability to communicate with the first device using the same type of parameters with different settings in the Attach process after random access, for example, to the first device An attach request message may be sent, said attach request message including said throughput indication information. The second device may report this capability in the random results process, eg include the capability data in the random access message. The second device may further report this capability to the first device based on the device capability inquiry information sent by the first device after the first device sends the device capability inquiry information. However, the present invention does not limit it.

Optionally, in S110, the communication parameters are multiple access schemes for communication and/or basic physical layer parameters corresponding to said multiple access schemes. By way of example, the multiple access scheme for communication may be Orthogonal Frequency-division Multiple Access (OFDMA)/Single-carrier Frequency-Division Multiple Access (SC-FDMA). Multiple Access), and multiple access schemes derived from it, or other multiple access schemes available in future communication systems. Basic physical layer parameters corresponding to OFDMA/SC-FDMA and its derived multiple access schemes are Subcarrier Spacing, OFDM symbol length, Cyclic Prefix (CP) length, It is possible to include at least one parameter among sampling frequency, reference signal density and design for channel estimation and demodulation, etc., reference signal sequence configuration and resource window granularity.

In other words, a terminal device as both a network device or a communication device can adjust the definition of one or more of the above parameters based on the network conditions and/or service conditions of the communication network in which it resides. For example, subcarrier spacing, OFDM symbol length, CP length, sampling frequency, density and design of reference signals for channel estimation and demodulation, etc. can be increased or decreased according to actual needs. . By way of example, Doppler frequency shifts can occur between communicating parties when they are in relative motion. The faster the relative movement, the larger the Doppler frequency shift, which requires a larger subcarrier spacing and a larger adjustment of the reference signal density for correct demodulation. When the channel environment changes, phenomena such as delay spread, angular spread, propagation loss, and penetration loss occur. , the larger the size of the obstacle, the greater the transmission delay spread. A terminal device, both as a network device or a communication device, can adjust the sequence structure of the reference signal according to actual needs, for example, the sequence function generating the reference signal can be changed from a quasi-orthogonal sequence to a pseudo-random code or a Zadoff code. It can be adjusted to the Chu sequence, etc., and the resource window granularity (ie, the minimum size of the resource window in frequency domain and time domain) can also be adjusted according to actual needs.

Alternatively, in S110, the initial settings of the communication parameters may be default settings, in other words, the communication parameters are default parameters, and in Device-to-Device (D2D) communication, the terminal device broadcasts the default parameters through the Discovery Channel, and different frequency bands and different regions can have different default parameters.

Alternatively, in S110, the communication parameter initial settings may be settings determined by both parties during random access. at least one of radio channel transmission conditions between the first device and the second device, communication capabilities of the first device and the second device, and service type when starting random access of the second device Initial settings of the communication parameters can be established based on the parameters. The first device determines the initial settings of the communication parameters and then transmits the initial settings of the communication parameters to the second device.

Alternatively, before establishing communication with the second device, the first device determines radio channel transmission conditions between the first device and the second device from random access information from devices other than the second device. or the first device further communicates with the first device by data, signaling or feedback Channel State Indicator information sent by a device already in communication with the first device Radio channel transmission conditions with the second device can be obtained. The communication capabilities of the first device and the second device include, but are not limited to, the number of transmit and receive antennas, transmit power, receive power, bandwidth used for communication.

Specifically, the terminal device as a network device or as both a communication device, the channel condition estimated by the random access sequence, the determined distance of the two communication devices, and the terminal device initiates random access for what type of service. Based on information such as whether the terminal device is accessing the communication network for the first time, the setting of the communication parameters can be determined. For example, in random access, a network device may determine a frequency band to allocate to a terminal for use based on service needs or other information, and the frequency band may be a terminal's random access. It may be the frequency band that starts the random access of the terminal device, and it may not be the frequency band that starts the random access of the terminal device.

Optionally, the first device may transmit the communication parameter initialization to the second device by including the communication parameter initialization in a random access response message. The first device may further transmit the communication parameter initialization to the second device in a manner that transmits other messages containing the communication parameter initialization to the second device.

Specifically, when network conditions change during communication, the terminal device as a network device or both can adjust communication parameter settings in real time. Changes in network conditions may be due to changes in the channel environment between the terminal and network equipment (e.g., serving base station and neighboring base stations) or between the terminal as both communicators. For example, there may be channel changes due to the frequency band being used during communication, antennas and mobility, or channel environment changes due to the mobility of both communicating terminals. Changes in network conditions may be due to changes in network load and interference, and changes in network conditions may be due to changes in the data rate and/or energy consumption demands of applications in the network. The present invention is not limited to these.

In an embodiment of the present invention, optionally, the terminal device as both the network device or the communication device can obtain the network status and/or the service status by its own survey, and the terminal device as the network device or the communication device can: Further, it is possible to receive reported status information of the terminal or one of the terminals as communication both, from which the network status and/or the service status can be obtained.

Optionally, in S120, specifically receiving parameter adjustment request information transmitted by the second device for requesting adjustment of one or more communication parameter settings in the communication parameters; One or more of the communication parameters are adjusted based on the parameter adjustment request information.

In other words, the second device can request adjustment of parameters from the first device when the service starts or when the service is changed or the radio signal environment changes. Alternatively, the second device sends request information to the first device for requesting adjustment of communication parameters, and the first device, after receiving said request information, measures network conditions by itself, e.g. , it is possible to determine whether the network state has changed according to the quality of the data transmitted by the second device received, and the network state transmitted by the terminal device of the same type as the second device in the communication network. and/or by receiving a status report to indicate service status, it can be determined whether the network status and/or service status has changed, and specifically which communication parameters to adjust. After confirming and completing the adjustment, the result of the adjustment is notified to the second device.

Further, the parameters can be adjusted using a handshaking mechanism, i.e., the first device receives the parameter adjustment request information sent by the second device, and then successfully receives the parameter adjustment request information. confirmation information (eg, one confirming ACK frame can respond) to the second device. If the second device has not received a response to the parameter adjustment request information of the first device within a scheduled time, the second device may send the parameter adjustment request information to the first device again, or communication parameter settings before requesting the adjustment of the first device, and the first device should be able to receive and transmit information using the pre-adjusted and post-adjusted parameters. be.

Optionally, at S120, receive state information transmitted by said second device specifically for indicating network state and/or service state; Or adjust the settings of multiple communication parameters.

Specifically, the second device sends the network state and/or service state to the first device, for example, service change, channel quality change due to environmental change (measurement results such as Doppler frequency shift, transmission loss, delay spread, etc. or channel quality indications quantified by survey results), etc., can be reported. After receiving the network status and/or service status reported by the second device, the first device actively adjusts the communication parameters and notifies the second device of the adjusted result. The second device can periodically or aperiodically report network status and/or service status to the first device, and the invention is not so limited.

Further, the second device can report its own measured network state and/or service state to the first device at the same time as sending parameter adjustment request information for requesting adjustment of communication parameters to the first device. , after receiving the parameter adjustment request information, the first device adjusts the communication parameters based on the network state and/or service state reported by the second device, and sends the result after the adjustment to the second device. Notice.

Optionally, the first device may send said parameter adjustment indication information to said second device via a physical layer control channel, e.g. Radio Resource Control) connection, different RRC connections may have different communication parameters, and for each connection (carrier or base station), the adjustment of communication parameters is unified. (i.e. shared by multiple connections) or independent physical layer control channel of the connection, the physical layer control channel being a new physical downlink control channel. Also good.

Otherwise, the first device can further inform the second device of the parameter adjustment result through a channel such as a paging channel or a broadcast channel. The invention is not so limited.

Also, the first device may select to send to the second device an adjustment result of only the communication parameters that have been adjusted, the first device further comprising the communication parameters that have been adjusted and the communication parameters that have been adjusted You can choose to send all non-existent communication parameters to the second device. Furthermore, the adjustment result transmitted from the first device may be expressed in the form of absolute values or may be expressed in the form of relative values. By way of example, if the subcarrier spacing before adjustment is 15 kHz, the subcarrier spacing needs to be increased to reduce the impact of Doppler frequency shifts on accurate demodulation of the signal. At this time, the first device may directly notify the second device that the adjusted subcarrier spacing is 20 kHz, or may notify the second device that the adjusted subcarrier spacing is equal to the pre-adjusted subcarrier spacing. It may be notified that it is 5 kHz greater than the carrier spacing. The invention is not so limited.
