Description

A kind of method and apparatus sending signal
Technical field
This application involves wireless communication technology field more particularly to a kind of method and apparatus for sending signal.
Background technique
Currently, mainly proposing two kinds of base station, respectively long term evolution in the 5th Generation Mobile Communication System The base station (LongTerm Evolution, LTE) and base station (New Radio, NR) of newly eating dishes without rice or wine.For the base station of both types, Function is similar, and the main distinction is to dispose the difference of frequency range.In the prior art, the base station NR major deployments are in high-frequency band, and LTE base station major deployments are in low frequency band.Since in a wireless communication system, the frequency of carrier wave is higher, and path loss is bigger, on Row covering is poorer, and the base station NR is due to being deployed in high-frequency band, the base station NR has that uplink covering is limited.
In order to solve the problems, such as that uplink covering in the base station NR is limited, related technical personnel propose following solution: in LTE When the ascending load of base station is lower, the base station NR is by the uplink carrier resource of shared LTE base station, in this way, LTE base station can be improved Ascending resource utilization rate, and the uplink covering of the base station NR can be improved.For example, as shown in Figure 1a, the uplink working frequency range of LTE base station For 1.75GHz, downlink working frequency range is 1.85GHz, and uplink working frequency range 1.75GHz is tied up with downlink working frequency range 1.85GHz phase It is fixed.The uplink working frequency range and downlink working frequency range of the base station NR are 3.5GHz.When the ascending load of LTE base station is lower, NR Base station can carry out uplink communication using the up-link carrier of the 1.75GHZ of LTE base station.Certainly, as shown in Figure 1 b, the base station NR can also be with Uplink communication is carried out using uplink supplement (supplementary uplink, SUL) carrier wave, it can not portion on the SUL carrier wave Affix one's name to LTE system.
Meanwhile in the prior art, terminal device can access base station in the following way:
Step A: receiving the downlink synchronous signal of base station, synchronous with base station holding according to the downlink synchronous signal；
Step B: the notification message that base station is sent is received, carries channel number in the notification message；
Step C: the frequency or centre frequency of up-link carrier are calculated according to the channel number, for example, can be according to following Formula calculates the frequency of up-link carrier, FUL=FUL_low+0.1(NUL–NOffs-UL), the FULThe frequency of up-link carrier is represented, FUL_lowFor the minimum upstream frequency of up-link carrier, the NULRepresent channel number, the NOffs-ULRepresent the minimum of up-link carrier Upstream frequency number；
Step D: uplink sub-carrier is mapped on up-link carrier；
Step E: uplink is carried out using the uplink sub-carrier after mapping.
In the prior art, as shown in Fig. 2, there are mainly two types of subcarrier maps mode, respectively the first mapping mode and Second mapping mode.Wherein, the first mapping mode is by the centralizing mapping of uplink sub-carrier to above-mentioned calculated up-link carrier Frequency, the second mapping mode be by the centralizing mapping of uplink sub-carrier to the frequency shift (FS) 7.5KHz's relative to up-link carrier At frequency.
For convenience of description, two kinds of terminals, respectively LTE terminal and NR terminal are defined below, the LTE terminal is selection Terminal of the LTE base station as serving BS, the NR terminal are to select the base station NR as the terminal of serving BS.Currently, for The transmitting uplink data of LTE terminal generallys use the second way and is mapped, and the transmitting uplink data of NR terminal is usually adopted It is mapped with first way.And when the ascending resource that LTE base station is shared in the base station NR carries out transmitting uplink data, in order to keep away Exempt to interfere with each other with LTE terminal, NR terminal can be mapped using the second way.Thus, it could be seen that mobile logical in the 5th generation In letter system, since NR terminal supports two kinds of mapping modes, then when NR terminal is in uplink, using the first mapping side Formula or the second mapping mode, there is no preferable solutions.
