[0030] Figure 1 The flowchart of a communication method according to an embodiment of the present disclosure is schematically shown.

[0031] In step S110, the terminal reports uplink capability information of the terminal to the network device, where the uplink capability information includes an uplink frequency band supported by the terminal and an uplink concurrent frequency band supported by the terminal.

[0032] The network device receives the uplink capability information uploaded by the terminal and can generate indication information including the frequency band used for uplink transmission of the terminal according to the uplink capability information, so as to instruct the terminal to perform uplink transmission according to the frequency band in the indication information.

[0033] The number of uplink frequency bands supported by the terminal is greater than the concurrent uplink frequency bands of the terminal.

[0034] In an exemplary embodiment, the number of uplink frequency bands supported by the terminal is N, where N is a positive integer greater than or equal to 3. In the following examples, N is a positive integer greater than or equal to 3, and the uplink concurrent frequency band of the terminal is 1 or 2, but the present disclosure is not limited thereto. In other embodiments, the method provided in the embodiment of the present disclosure can be applied as long as the number of uplink frequency bands supported by the terminal is greater than the uplink concurrent frequency band of the terminal.

[0035] In an exemplary embodiment, the uplink capability information may further include a transmitter dynamic switching capability between some frequency band pairs in the uplink frequency band supported by the terminal, each frequency band pair including two uplink frequency bands in the uplink frequency band supported by the terminal.

[0036] In an exemplary embodiment, the reported uplink capability information may further include frequency band pairs supporting dynamic switching.

[0037] In an exemplary embodiment, the uplink capability information may further include a transmitter dynamic switching capability between all frequency band pairs in the uplink frequency bands supported by the terminal, each frequency band pair including two uplink frequency bands in the uplink frequency bands supported by the terminal.

[0038] In an exemplary embodiment, the transmitter dynamic switching capability between all frequency band pairs in the uplink frequency band supported by the terminal is reported uniformly.

[0039] In an exemplary embodiment, the uplink capability information further includes frequency band pairs that cannot be concurrently performed in the uplink frequency bands supported by the terminal.

[0040] In step S120, the terminal receives indication information including a frequency band used for uplink transmission of the terminal from the network device.

[0041] The network device may send the generated indication information to the terminal. After receiving the indication information from the network device, the terminal may perform uplink transmission on the frequency band indicated by the indication information according to the indication information.

[0042] In the embodiment of the present disclosure, the frequency band used by the terminal for uplink transmission indicated in the indication information belongs to the uplink frequency band supported by the terminal in the uplink capability information uploaded by the terminal.

[0043] In an exemplary embodiment, the uplink concurrent transmission frequency band includes that the terminal supports single transmission on one uplink frequency band. The indication information includes that the terminal performs uplink transmission on one uplink frequency band supported by the terminal at any time.

[0044] In an exemplary embodiment, the uplink capability information further includes M carriers supported in each uplink frequency band supported by the terminal, where M is a positive integer greater than or equal to 1. The indication information also includes that the terminal performs uplink transmission on one or more of the M carriers in each uplink frequency band supported by the terminal.

[0045] In an exemplary embodiment, the uplink concurrent transmission frequency band includes that the terminal supports two uplink frequency bands concurrently. The indication information includes that the two sets of transmitters of the terminal both perform uplink transmission in parallel on the same uplink frequency band among the uplink frequency bands supported by the terminal; or, according to the indication information, the two sets of transmitters of the terminal respectively perform uplink transmission in parallel on two different uplink frequency bands among the uplink frequency bands supported by the terminal; or, according to the indication information, the first set of transmitters of the two sets of transmitters of the terminal performs uplink transmission on one uplink frequency band among the uplink frequency bands supported by the terminal, and the second set of transmitters does not transmit signals.

[0046] In an exemplary embodiment, the uplink capability information further includes M carriers supported in each uplink frequency band supported by the terminal, where M is a positive integer greater than or equal to 1. The indication information also includes that the terminal performs uplink transmission on one or more of the M carriers in each uplink frequency band supported by the terminal.

[0047] In an exemplary embodiment, the method may further include: if the uplink frequency band of the transmitter of the terminal changes at two consecutive moments, the terminal cannot send uplink signals in each uplink frequency band during the transmitter switching time.

[0048] In the disclosed embodiment, the transmitter switching time may range from tens of microseconds to hundreds of microseconds.

[0049] In an exemplary embodiment, the method may further include: if the transmitter switching time of each frequency band pair to be switched is different, independently reporting the transmitter switching time of each frequency band pair.

[0050] In an exemplary embodiment, the method may further include: if the transmitter switching time of each frequency band pair to be switched is the same, uniformly reporting the transmitter switching time of all frequency band pairs.

[0051] The communication method provided in the embodiments of the present disclosure aims at a scenario in which the number of uplink frequency bands supported by a terminal is greater than the uplink concurrent frequency bands of the terminal. The terminal reports the uplink capability information of the terminal to a network device, and the uplink capability information carries the uplink frequency bands supported by the terminal and the uplink concurrent frequency bands supported by the terminal. Thus, the network device can generate and send to the terminal indication information including the frequency bands used for uplink transmission by the terminal based on the received uplink capability information of the terminal, thereby realizing dynamic switching among the uplink frequency bands supported by the terminal when the terminal performs uplink transmission, and flexibly utilizing all uplink spectrum resources.

[0052] The method provided in the embodiment of the present disclosure is described below by way of example, but the present disclosure is not limited thereto.

[0053] The method provided by the embodiment of the present disclosure can be used for uplink multi-band transmission capability reporting, configuration and transmission, taking the scenario of multi-band networking of low frequency below 1GHz (such as 800MHz, 900MHz and other low frequency bands), medium frequency around 2GHz, and high frequency of 3.5GHz and above in the mobile access network FR1 as an example, each frequency band has one or more carrier units. And for the target terminal that only has the uplink transmission capability of up to 2 times, the embodiment of the present disclosure can send uplink signals on 3 or more uplink frequency bands based on the terminal with up to dual concurrent uplink capability.

[0054] Based on the current status of actual terminals, the terminal proposed in the embodiment of the present disclosure can be configured with more than or equal to 3 uplink frequency bands, and the uplink frequency bands activated and sending uplink signals at the same time are 1 or 2. This solves the problem that the existing standard configuration has the same number of activated frequency bands and cannot flexibly utilize all uplink spectrum resources.

[0055] The solution provided by the embodiments of the present disclosure can be used for NR system networking scenarios with three or more frequency bands. 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 has the ability to simultaneously perform single or dual uplink transmissions, that is, at most one or two uplink frequency bands among the N uplink frequency bands can perform parallel uplink transmissions. Based on the terminal's capability reporting and network scheduling, the uplink frequency band for actual uplink transmission by the terminal can be dynamically switched / changed among the N uplink frequency bands.

[0056] For example, a terminal can report the following capabilities:

[0057] The ability to support configuration on N uplink frequency bands (e.g., frequency band A, frequency band B, frequency band C, etc.) and only support 1 or 2 uplink concurrent frequency bands at the same time (i.e., only 1 or 2 uplink frequency bands are active);

[0058] The ability to dynamically switch transmitters between some or all of the N uplink frequency bands (i.e., one frequency band pair includes two uplink frequency bands);

[0059] The terminal cannot perform concurrent operations on some of the frequency bands;

[0060] The capability of supporting uplink transmission of one or more carriers in each uplink frequency band.

[0061] In the embodiment of the present disclosure, in the capability of dynamic switching of transmitters between some or all frequency band pairs among N uplink frequency bands (i.e., 1 frequency band pair includes 2 uplink frequency bands), if switching between all frequency band pairs among N uplink frequency bands can be supported, then they will be reported uniformly in the capability report without enumerating all frequency band pairs.

[0062] For example, if N=3, it is assumed that the terminal configuration supports band A, band B and band C, and the terminal supports switching between band A and band B, switching between band B and band C, and switching between band A and band C.

[0063] In the embodiment of the present disclosure, in the capability of dynamically switching transmitters between some or all frequency band pairs among N uplink frequency bands (i.e., 1 frequency band pair includes 2 uplink frequency bands), if switching between some frequency band pairs among N uplink frequency bands can be supported, all dynamically switchable frequency band pairs are reported.

[0064] For example, if N=3, assuming that the terminal configuration supports band A, band B and band C, and the terminal can support switching between band A and band B, and switching between band B and band C, but does not support switching between band A and band C, then the band pair including band A and band B, and the band pair including band B and band C can be reported.

[0065] In the disclosed embodiment, the ability of the terminal to be unable to perform concurrent uplink in some frequency bands is considered based on a survey of the terminal. In some adjacent frequency bands, such as 800 / 900 MHz, the terminal cannot perform concurrent uplink.

[0066] In the embodiment of the present disclosure, for a terminal capable of up to single uplink transmission at the same time, the terminal can perform single uplink transmission in only one uplink frequency band at any time through scheduling by a base station or a network. This can be applicable to any uplink frequency band among N uplink frequency bands.

[0067] For example, when N=3, the terminal performs uplink transmission only in frequency band A, frequency band B, or frequency band C at the same time. Other situations can be deduced by analogy.

[0068] In the embodiment of the present disclosure, if the terminal can support M carriers for transmission in a certain uplink frequency band, based on the scheduling of the base station, it can actually transmit on one or more of the M carriers. It can be applicable to any uplink frequency band in the N uplink frequency bands.

[0069] In the disclosed embodiment, for a terminal capable of up to two simultaneous uplink transmissions, the two sets of transmitters can be used in two uplink frequency bands, with a single uplink transmission in each frequency band, or can be used in one uplink frequency band. It can be applicable to any uplink frequency band among the N uplink frequency bands.

[0070] For example, at a certain moment, any of the following three states can exist:

[0071] If both transmitters are in one of the N uplink frequency bands, they can transmit in both uplink frequency bands.

[0072] Two sets of transmitters are respectively in two uplink frequency bands among the N uplink frequency bands, and can transmit in these two uplink frequency bands alone, or in two uplink frequency bands simultaneously;

[0073] One set of transmitters can transmit in one uplink frequency band among N uplink frequency bands; the other set of transmitters does not send any signal.

[0074] In the embodiment of the present disclosure, if the terminal can support M carriers for transmission in a certain frequency band, based on the scheduling of the base station, it can actually transmit on one or more of the M carriers. It can be applicable to any uplink frequency band in the N uplink frequency bands.

[0075] In the disclosed embodiment, based on the terminal capability report, the transmitter of the terminal can dynamically switch between any frequency band pairs (ie, 2 frequency bands) among the N row frequency bands, or dynamically switch between some of the frequency band pairs therein.

[0076] Based on terminal implementation, multiple carriers in the same frequency band are transmitted in parallel using the same transmitter. If there are multiple carriers in a frequency band, the maximum number of antennas that can be used for uplink transmission of multiple carriers is the same, and the actual number of ports for each carrier to transmit is based on network scheduling.

[0077] In the disclosed embodiment, based on the scheduling of network equipment such as a base station, the terminal performs uplink transmission on the corresponding uplink frequency band (pair) and carrier; if the uplink frequency band of a transmitter of the terminal changes (i.e., the transmitter is switched) for two consecutive moments, it takes a certain time (tens or hundreds of microseconds) to switch, which is called the transmitter switching time. During the transmitter switching time, no uplink signal can be sent on each uplink frequency band.

[0078] The transmitter switching time may be reported independently for each frequency band pair, that is, the transmitter switching time for each frequency band pair may be different, for example, the transmitter switching time between frequency band A and frequency band B is 140us, and the transmitter switching time between frequency band B and frequency band C is 35us.

[0079] The transmitter switching time can be uniformly reported 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.

[0080] The communication method provided by the embodiments of the present disclosure is aimed at the scenario where there are multiple low frequencies below 1 GHz (such as 800 MHz, 900 MHz and 700 MHz), medium 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 a maximum of dual-transmission concurrent capability in the uplink, thereby achieving efficient and dynamic utilization of uplink spectrum resources.

[0081] The communication method provided by the embodiment of the present disclosure not only realizes the transmission of three or more uplink frequency bands using two sets of transmitters, but also takes into account the problem that some adjacent uplink frequency bands cannot be concurrent. The method provided by the embodiment of the present disclosure focuses on the actual deployment scenario of the 5G network, combines the terminal capability level, and improves the utilization rate of the precious spectrum.

[0085] In step S220, the network device sends indication information including a frequency band used for uplink transmission of the terminal to the terminal.

[0086] The number of uplink frequency bands supported by the terminal is greater than the concurrent uplink frequency bands of the terminal.
