In an exemplary embodiment, the method may further include: and if the switching time of the transmitter of each frequency band pair is different, independently reporting the switching time of the transmitter of each frequency band pair.
In an exemplary embodiment, the method may further include: and if the switching time of the transmitters of each frequency band pair is the same, uniformly reporting the switching time of the transmitters of all the frequency band pairs.
The communication method provided by the embodiment of the present disclosure reports, for a scenario in which the number of uplink frequency bands supported by a terminal is greater than that of uplink concurrent frequency bands of the terminal, uplink capability information of the terminal to a network device through the terminal, where the uplink capability information carries 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, indication information including a frequency band used for uplink transmission of the terminal according to the received uplink capability information of the terminal, thereby implementing dynamic switching in the uplink frequency bands supported by the terminal when the terminal performs uplink transmission, and being capable of flexibly utilizing all uplink spectrum resources.
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 embodiment of the disclosure can be used for reporting, configuring and transmitting the capability of uplink multi-band transmission, taking the scenario of multi-band networking with low frequency below 1GHz (e.g. low frequency bands such as 800MHz and 900 MHz), medium frequency around 2GHz, and high frequency above 3.5GHz in a mobile access network FR1 as an example, and each frequency band has one or more carrier units. And aiming at the target terminal only having the capacity of 2 uplink transmissions at most, the embodiment of the present disclosure can transmit uplink signals on 3 or more uplink frequency bands based on the terminal having the capacity of dual uplink transmissions at most.
Based on the current situation of an actual terminal, the terminal provided in the embodiment of the present disclosure may configure more than or equal to 3 uplink frequency bands, and the number of the uplink frequency bands for simultaneously activating and transmitting uplink signals is 1 or 2. The problem that all uplink spectrum resources cannot be flexibly utilized due to the fact that the number of the existing standard configuration frequency bands is the same as that of the existing standard configuration frequency bands is solved.
The scheme provided by the embodiment of the disclosure can be oriented to a networking scene of 3 or more frequency bands of an NR system, a terminal can configure and support N (N > = 3) uplink frequency bands, and each uplink frequency band has 1 or more carriers; meanwhile, the terminal has the capacity of single transmission or double transmission at most at the same time of uplink, namely, the parallel uplink transmission is carried out on at most 1 or 2 uplink frequency bands in the N uplink frequency bands; based on the capability report and network scheduling of the terminal, the uplink frequency band of the terminal actually performing uplink transmission can be dynamically switched/changed in the N uplink frequency bands.
For example, the terminal may report the following capabilities:
the capability of supporting configuration in N uplink frequency bands (for example, frequency bands a, B, C, and the like) and supporting only 1 or 2 uplink concurrent frequency bands (that is, only 1 or 2 uplink frequency bands are in an active (active) state);
the capability of dynamically switching transmitters between part or all frequency band pairs (i.e. 1 frequency band pair comprises 2 uplink frequency bands) in the N uplink frequency bands;
the terminal has the capability that partial band pairs cannot be concurrent in the terminal;
the capability of supporting 1 or more carriers for uplink transmission in each uplink frequency band.
In the embodiment of the present disclosure, in the capability of dynamically switching the transmitter between part or all of the N uplink frequency band pairs (that is, 1 frequency band pair includes 2 uplink frequency bands), if the switching between all of the N uplink frequency band pairs can be supported, then the capability report is uniformly reported without listing all of the frequency band pairs.
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.
In the embodiment of the present disclosure, in the capability of dynamically switching the transmitter between part or all of the N uplink frequency band pairs (that is, 1 frequency band pair includes 2 uplink frequency bands), if the switching between part of the N uplink frequency band pairs can be supported, all dynamically switchable frequency band pairs are reported.
For example, if N =3, assuming that the terminal configuration supports the frequency band a, the frequency band B, and the frequency band C, and the terminal may support the switching between the frequency band a and the frequency band B, the switching between the frequency band B and the frequency band C, but does not support the switching between the frequency band a and the frequency band C, the terminal may report the frequency band pair including the frequency band a and the frequency band B, and the frequency band pair including the frequency band B and the frequency band C.
In the embodiment of the present disclosure, the capability of the terminal that part of the frequency band pairs cannot be concurrent is considered based on the investigation on the terminal, and the terminal cannot be uplink concurrent in some adjacent frequency bands, for example, 800/900 MHz.
In the embodiment of the present disclosure, for a terminal with uplink simultaneous single transmission capability, through base station or network scheduling, the terminal only performs uplink single transmission in 1 uplink frequency band at any time. And is applicable to any uplink frequency band of the N uplink frequency bands.
For example, when N =3, the terminal performs uplink transmission only in band a, band B, or band C at the same time. Other cases may be analogized.
In the embodiment of the present disclosure, if a terminal can support M carriers to transmit in a certain uplink frequency band, the terminal can actually transmit on 1 or more carriers of the M carriers based on scheduling of a base station. And is applicable to any uplink frequency band of the N uplink frequency bands.
In the embodiment of the present disclosure, for a terminal with uplink simultaneous maximum dual-transmission capability, two sets of transmitters that are concurrently transmit uplink signals in two uplink frequency bands and in each frequency band, or in 1 uplink frequency band. And the method can be applied to any uplink frequency band in the N uplink frequency bands.
For example, at some point in time, there may be any one of the following 3 states:
the 2 sets of transmitters are all in 1 uplink frequency band of the N uplink frequency bands, namely, the transmitters can transmit in the uplink frequency band in a double-transmitting mode;
the 2 sets of transmitters respectively transmit in 2 uplink frequency bands of the N uplink frequency bands, namely, the two uplink frequency bands can be transmitted singly and the two uplink frequency bands can be transmitted simultaneously;
1 set of transmitters can transmit in a single uplink frequency band in 1 uplink frequency band of N uplink frequency bands; the other 1 set of transmitters do not transmit signals.
In the embodiment of the present disclosure, if a terminal can support M carriers to transmit in a certain frequency band, the terminal can actually transmit on 1 or more carriers of the M carriers based on scheduling of a base station. And is applicable to any uplink frequency band of the N uplink frequency bands.
In the embodiment of the present disclosure, based on the terminal capability report, the transmitter of the terminal may dynamically switch between any frequency band pair (i.e., 2 line frequency bands) in the N line frequency bands, or dynamically switch between partial frequency band pairs therein.
Based on the terminal implementation, a plurality of carriers in the same line frequency band are transmitted in parallel by the same set of transmitter. If a plurality of carriers exist in one line frequency band, the maximum number of antennas which can be used for uplink transmission of the plurality of carriers is the same, and the number of ports which are actually transmitted by each carrier is based on network scheduling.
In the embodiment of the present disclosure, based on a network device such as a base station scheduling, a terminal performs upload transmission on a corresponding uplink frequency band (pair) and a carrier; if the uplink frequency band of a certain transmitter of the terminal changes (i.e., transmitter switching is performed) at two consecutive time points, a certain time (tens or hundreds of microseconds) is required for switching, and this time is called transmitter switching time. During the switching time of the transmitter, no uplink signal can be transmitted on each uplink frequency band.
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 the frequency band a and the frequency band B is 140us, and the transmitter switching time between the frequency band B and the frequency band C is 35us.
The transmitter switching time can report all the frequency band pairs supporting the transmitter switching in the frequency band combination in a unified way, namely 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 embodiment of the disclosure is oriented to a scenario that multiple low frequencies below 1GHz (such as 800MHz, 900MHz and 700 MHz), medium frequencies around 2GHz (such as 1.8GHz and 2.1 GHz), high frequencies above 3.5GHz and high frequencies above are simultaneously present in FR1 in an access network, the total frequency band number is greater than or equal to 3, and a terminal only has the capacity of uplink concurrent transmission at most, thereby realizing efficient and dynamic utilization of uplink spectrum resources.
The communication method provided by the embodiment of the disclosure not only realizes the transmission of 3 or more uplink frequency bands by using 2 sets of transmitters, but also considers the problem that part of adjacent uplink frequency bands cannot be transmitted concurrently. The method provided by the embodiment of the disclosure focuses on the actual deployment scene of the 5G network, and improves the utilization rate of precious frequency spectrum by combining with the terminal capability level.
