In the communication method provided by the embodiments of the present disclosure, for the scenario where the number of uplink frequency bands supported by the terminal is greater than the number of uplink concurrent frequency bands of the terminal, the terminal reports the uplink capability information of the terminal to the network device, and carries the uplink capability information in the uplink capability information. The uplink frequency bands supported by the terminal and the uplink concurrent frequency bands supported by the terminal, so that the network device can generate and send to the terminal information including the frequency band used by the terminal for uplink transmission according to the received uplink capability information of the terminal The indication information enables the terminal to perform dynamic switching among the uplink frequency bands supported by the terminal when performing uplink transmission, so that all uplink spectrum resources can be flexibly utilized.

The methods provided by the embodiments of the present disclosure are illustrated below, but the present disclosure is not limited thereto.

The method provided by the embodiments of the present disclosure can be used for capability reporting, configuration, and transmission of uplink multi-band transmission, so as to be applied to low frequencies below 1 GHz (such as low frequency bands such as 800 MHz and 900 MHz), intermediate frequencies around 2 GHz, and 3.5 GHz in the mobile access network FR1. Taking the above high-frequency multi-band networking scenario as an example, each frequency band has one or more carrier units. And for the target terminal only has a maximum uplink capability of 2 transmissions, the embodiments of the present disclosure can send uplink signals on 3 or more uplink frequency bands based on a terminal with a maximum uplink dual concurrent capability.

Based on the current situation of the actual terminal, the terminal proposed by the embodiment of the present disclosure can be configured with more than or equal to 3 uplink frequency bands, and there are 1 or 2 uplink frequency bands for simultaneously activating and sending uplink signals. It solves the problem that the existing standard configuration and the number of activated frequency bands are the same, and all uplink spectrum resources cannot be flexibly utilized.

The solution provided by the embodiments of the present disclosure can be oriented to the networking scenario of 3 or more frequency bands in the NR system. The terminal can be configured to support N (N>=3) uplink frequency bands, and each uplink frequency band has one or more carriers; at the same time, the terminal It has the capability of uplink simultaneous single transmission or dual transmission at most, that is, at most 1 or 2 uplink frequency bands in the N uplink frequency bands can perform parallel uplink transmission; based on the terminal's capability reporting and network scheduling, the uplink frequency band that the terminal actually performs uplink transmission can be Dynamically switch/change among N uplink frequency bands.

For example, a terminal can report the following capabilities:

Support configuration in N uplink frequency bands (for example, it can be called frequency band A, frequency band B, frequency band C, etc.), and only support 1 or 2 uplink concurrent frequency bands at the same time (that is, only 1 or 2 uplink frequency bands are active (active) ) state) ability;

Ability to dynamically switch transmitters among some or all of the N uplink frequency band pairs (that is, one frequency band pair includes two uplink frequency bands);

The ability of the terminal to be unable to run concurrently in some of the frequency bands;

In each uplink frequency band, it can support the uplink transmission capability of one or more carriers.

In the embodiment of the present disclosure, in the dynamic switching capability of transmitters among some or all frequency band pairs in N uplink frequency bands (that is, one frequency band pair includes two uplink frequency bands), if all frequency band pairs in N uplink frequency bands can be supported In case of handover between different frequency bands, report them uniformly in the capability report, instead of enumerating all the frequency band pairs.

For example, if N=3, it is assumed that the terminal is configured to support frequency band A, frequency band B, and frequency band C, and the terminal supports switching between frequency band A and frequency band B, switching between frequency band B and frequency band C, and switching between frequency band A and frequency band C. switch between.

In the embodiment of the present disclosure, in the dynamic switching capability of the transmitter among some or all frequency band pairs in the N uplink frequency bands (that is, one frequency band pair includes two uplink frequency bands), if some frequency band pairs in the N uplink frequency bands can be supported If there is switching between them, all frequency band pairs that can be dynamically switched are reported.

For example, if N=3, it is assumed that the terminal configuration supports frequency band A, frequency band B and frequency band C, and the terminal can support switching between frequency band A and frequency band B, switching between frequency band B and frequency band C, but does not support frequency band A and frequency band For switching between frequency bands C, the frequency band pair including frequency band A and frequency band B, and the frequency band pair including frequency band B and frequency band C may be reported.

In the embodiments of the present disclosure, the ability of the terminal to be incapable of concurrency in some frequency bands is considered based on the research on the terminal. In some adjacent frequency bands, such as 800/900MHz, the terminal cannot be concurrent in uplink.

In the embodiments of the present disclosure, for a terminal with the maximum uplink simultaneous single transmission capability, through base station or network scheduling, the terminal performs uplink single transmission in only one uplink frequency band at any time at the same time. It is applicable to any uplink frequency band in the N uplink frequency bands.

For example, when N=3, the terminal only performs uplink transmission in the frequency band A, or the frequency band B, or the frequency band C at the same time. Other situations can be deduced by analogy.

In the embodiment of the present disclosure, if the terminal can support transmission on M carriers in a certain uplink frequency band, based on base station scheduling, it can actually transmit on one or more carriers among the M carriers. It is applicable to any uplink frequency band in the N uplink frequency bands.

In the embodiment of the present disclosure, for a terminal capable of uplink simultaneous dual transmission at most, two sets of concurrent transmitters can perform uplink single transmission in two uplink frequency bands, or concurrently in one uplink frequency band. It is applicable to any uplink frequency band in the N uplink frequency bands.

For example, at a certain moment, any of the following 3 states can exist:

Both sets of transmitters are in one of the N uplink frequency bands, and can be used for dual transmission in this uplink frequency band;

The 2 sets of transmitters are respectively in 2 uplink frequency bands of the N uplink frequency bands, and can be used for single transmission in these two uplink frequency bands, and the two uplink frequency bands can be concurrent;

One set of transmitters can send a single signal in one of the N uplink frequency bands; the other set of transmitters does not send signals.

In the embodiment of the present disclosure, if the terminal can support transmission on M carriers in a certain frequency band, based on base station scheduling, it can actually transmit on one or more carriers among the M carriers. It is applicable to any uplink frequency band in the N uplink frequency bands.

In the embodiment of the present disclosure, based on the terminal capability report, the transmitter of the terminal can dynamically switch between any pair of frequency bands (that is, two frequency bands) in the N row frequency bands, or dynamically switch between some pairs of frequency bands.

Based on terminal implementation, multiple carriers in the same row frequency band use the same set of transmitters for parallel transmission. If there are multiple carriers in one upstream frequency band, the maximum number of antennas that can be used by multiple carriers for uplink transmission is the same, and the actual number of ports for each carrier is based on network scheduling.

In the embodiments of the present disclosure, based on network equipment such as base station scheduling, the terminal uploads and transmits on the corresponding uplink frequency band (pair) and carrier; if two consecutive moments, the uplink frequency band of a certain transmitter of the terminal changes (i.e. Transmitter switching), it takes a certain time (tens or hundreds of microseconds) to switch, and this time is called the transmitter switching time. During the switching time of the transmitter, no uplink signal can be sent on each uplink frequency band.

The transmitter switching time can be reported independently for each frequency band pair, that is, the transmitter switching time of each frequency band pair can be different, for example, the transmitter switching time between frequency band A and frequency band B is 140us, and between frequency band B and frequency band C The switching time between transmitters is 35us.

The transmitter switching time may be reported uniformly for all frequency band pairs supporting transmitter switching in the frequency band combination, that is, the transmitter switching time of each frequency band pair is the same. For example, the transmitter switching time between all frequency band pairs is 140us.

The communication method provided by the embodiments of the present disclosure is aimed at the simultaneous existence of multiple low frequencies below 1 GHz (such as 800 MHz, 900 MHz and 700 MHz), intermediate frequencies around 2 GHz (such as 1.8 GHz, 2.1 GHz), and high frequencies of 3.5 GHz and above in FR1 in the access network. , the total number of frequency bands is greater than or equal to 3, and the terminal only has the maximum dual transmission and concurrent uplink capability, which realizes efficient and dynamic use of uplink spectrum resources.

The communication method provided by the embodiments of the present disclosure not only realizes the transmission of three or more uplink frequency bands by using two sets of transmitters, but also considers the problem that some adjacent uplink frequency bands cannot be concurrently transmitted. The method provided by the embodiments of the present disclosure focuses on the actual deployment scenario of the 5G network, and improves the utilization rate of the precious frequency spectrum in combination with the capability level of the terminal.
