Embodiment 2

The embodiment of the present invention also provides a frequency switching processing method, which is applied in a terminal. FIG. 3 is a schematic flowchart of a frequency switching processing method according to Embodiment 2 of the present invention; as shown in FIG. 3 , the method includes:

Wherein, the mapping set includes at least two sets of mapping relationships between identifiers and frequency adjustment parameters. The identifier is used as an index identifier, which is carried in the downlink control information of a specific format and is used to indicate the channel frequency adjustment information to be adjusted for PDSCH and/or PUSCH, so that the terminal can search for the mapping relationship based on the identifier and obtain the frequency adjustment to be adjusted corresponding to the identifier. parameter. The frequency adjustment parameter represents channel information to be adjusted, and the frequency adjustment parameter includes at least one of the following information: frequency point, frequency, and frequency range, indicating the frequency point, frequency or frequency range adjusted by the terminal. For examples of the mapping set, reference may be made to Table 1 and Table 2 in Embodiment 1, which are not described in detail in this embodiment. In practical applications, the network device configures the initial channel information for uplink and downlink. Taking the schematic shown in Table 1 or Table 2 as an example, the frequency adjustment parameter corresponding to channelID 0 can be pre-configured (the frequency adjustment parameter can include the uplink frequency adjustment parameter and / or downlink frequency adjustment parameters) for data transmission.

In this embodiment, the adjusting the frequency parameter based on the downlink control information of the specific format and the mapping set starting from the specific TTI indicated by the downlink control information of the specific format includes: downlink control based on the specific format The first identifier included in the information searches the mapping set, obtains the first frequency adjustment parameter corresponding to the first identifier, and starts from the specific TTI indicated by the downlink control information of the specific format based on the first frequency adjustment parameter Adjust the frequency parameter.

Specifically, after the terminal obtains the downlink control information in a specific format, take the downlink control information as DCI as an example, since the DCI includes multiple bits, at least one bit of the multiple bits represents an identifier, for example, at least one bit represents Table 1 The channelID shown in is 0 or 1. Based on this, the terminal can obtain the corresponding first identifier according to the bit representing the corresponding identifier in the DCI, for example, the channelID is 0 or 1, search the stored mapping set based on the first identifier, and obtain the first frequency adjustment corresponding to the first identifier parameter as the adjusted frequency parameter.

In this embodiment, the adjustment of the frequency parameter based on the downlink control information of the specific format and the mapping set starts from the specific TTI indicated by the downlink control information of the specific format, including: when the downlink control information of the specific format starts to adjust the frequency parameter When the information is used to schedule downlink user data, control downlink user data corresponding to the next TTI adjacent to the TTI where the downlink control information of the specific format is located to transmit downlink user data according to the adjusted downlink frequency parameter; and/or, when all When the downlink control information in the specific format is used for scheduling uplink user data, the uplink user data corresponding to the TTI where the downlink control information in the specific format is located four TTIs apart is controlled to transmit uplink user data according to the adjusted uplink frequency parameter.

Specifically, the downlink control information in the specific format is used to schedule data transmission on the downlink shared channel of the downlink TTI corresponding to the next TTI adjacent to the transmission time interval TTI where the downlink control information in the specific format is located; and/or, The downlink control information of the specific format is used to schedule data transmission on the uplink shared channel of the uplink TTI corresponding to the TTI where the downlink control information of the specific format is located four TTIs apart. Based on this, when the terminal receives the DCI as the downlink control information, it can receive and/or send data based on the indication of the DCI.

Specifically, the downlink control information may specifically be DCI. In this embodiment, a new DCI format is preconfigured. The DCI may include multiple bits, and at least one of the multiple bits represents an identifier. If the channelID shown is 0 or 1, the uplink and downlink channels corresponding to the determined channelID are adjusted according to the corresponding uplink frequency adjustment parameters and downlink frequency adjustment parameters. For another example, two bits can be used, the first bit represents the uplink channelID, and the second bit represents the downlink channelID. Both bits can be configured or only one of the bits can be configured; when only one of the bits is configured, Indicates that only the uplink or downlink frequency parameters are adjusted. In the embodiment of the present invention, the timing relationship between the configuration of downlink control information (such as DCI) and the scheduled downlink shared channel is as follows: the downlink shared channel is located at the next downlink TTI of the TTI where the downlink control information is located; the downlink control information (such as DCI) and the scheduling The timing relationship of the uplink shared channel is as follows: the uplink shared channel is located in the uplink TTI corresponding to four TTIs apart from the TTI where the downlink control information is located.

As an implementation manner, when the DCI received by the terminal as the downlink control information is used to adjust the uplink frequency parameter, the terminal sends uplink user data correspondingly according to the TTI where the DCI is located four TTIs apart. For example, as shown in Figure 2, the PDCCH in the n-5th TTI carries the DCI as downlink control information, and the indication of the DCI takes effect on the PUSCH corresponding to the nth TTI in the uplink channel with channelID=0, that is, the n-5th TTI 4 TTIs away from the nth TTI.

As another embodiment, when the DCI received by the terminal as downlink control information is used to adjust downlink frequency parameters, the terminal correspondingly receives downlink user data according to the next TTI adjacent to the TTI where the DCI is located. For example, as shown in FIG. 2 , the PDCCH in the nth TTI carries the DCI as downlink control information. The DCI indicates that the downlink channelID is modified to 1, and the modification of the n+1th TTI in the downlink channel with channelID=1 takes effect. In this embodiment, when the network device does not send the DCI as the downlink control information, the terminal does not need to activate the receiving function, and does not need to receive the corresponding user data, which saves power to a certain extent.

By adopting the technical solutions of the embodiments of the present invention, the DCI can flexibly switch the uplink and downlink frequency parameters (including switching the uplink and downlink carrier frequency points) at the TTI level during uplink and downlink data transmission. The scheduling switching can make resource utilization more fully, and also improve the user experience.
