TABLE 2
In practical application, the network device configures the initial channel information of the uplink and the downlink, and may pre-configure the frequency adjustment parameter with a channel id of 0 for data transmission, taking the schematic shown in table 1 as an example.
In this embodiment, the downlink control information in the specific format is used to schedule data transmission of a downlink shared channel of a downlink TTI corresponding to a next TTI adjacent to a TTI in a transmission time interval where the downlink control information in the specific format is located; and/or the downlink control information with the specific format is used for scheduling data transmission of an uplink shared channel of an uplink TTI corresponding to a TTI (transmission time interval) at which the downlink control information with the specific format is located, wherein the TTI is four TTIs apart.
Specifically, the downlink control information may be DCI, and a new DCI format is configured in advance in this embodiment, where the DCI may include multiple bits, and at least one bit of the multiple bits represents an identifier, for example, one bit may represent that a channeld shown in table 1 is 0 or 1, and then both an uplink channel and a downlink channel corresponding to the determined channeld are adjusted according to the corresponding uplink frequency adjustment parameter and the corresponding downlink frequency adjustment parameter. For another example, the uplink channel id may be represented by two bits, where the first bit represents the uplink channel id, the second bit represents the downlink channel id, and both bits may be configured by configuration or only one bit thereof may be configured; when only one bit is configured, it indicates that only the uplink or downlink frequency parameters are adjusted. The timing relationship between the downlink control information (e.g. DCI) configured and the scheduled downlink shared channel in the embodiment of the present invention is: the downlink shared channel is positioned at the next downlink TTI of the TTI where the downlink control information is positioned; the timing relationship between the downlink control information (e.g., DCI) and the scheduled uplink shared channel is as follows: the uplink shared channel is located in the uplink TTI corresponding to the TTI of the downlink control information at intervals of four TTIs.
Fig. 2 is a schematic timing diagram of downlink control information and a shared channel in a frequency point switching processing method according to an embodiment of the present invention; as shown in fig. 2, a channel corresponding to the initially used channeld 0, that is, a downlink channel and an uplink channel of which the initially used channeld is 0. As shown in fig. 2, the (n-5) th TTI includes a PDCCH and a PDSCH, where the PDCCH carries DCI as downlink control information; the DCI indication is valid for the PDSCH corresponding to the n-4 th TTI in the downlink channel with the channeld of 0. The PDCCH in the (n-5) th TTI carries DCI as downlink control information, and the indication of the DCI is valid in the PUSCH corresponding to the nth TTI in the uplink channel with the channeld of 0, that is, the (n-5) th TTI is separated from the nth TTI by 4 TTIs. And the PDCCH in the (n-2) th TTI bears DCI serving as downlink control information, the DCI indicates that the uplink channel ID is modified to be 1, and the modification of the (n + 2) th TTI takes effect in the uplink channel with the channel ID being 1. And the PDCCH bears DCI serving as downlink control information in the nth TTI, the DCI indicates that the downlink channel ID is modified to be 1, and the modification of the (n + 1) th TTI takes effect in the downlink channel with the channel ID being 1.
Further, the network device may transmit downlink data based on DCI as the downlink control information; for example, as shown in fig. 2, the PDCCH in the nth TTI carries DCI as downlink control information, where the DCI indicates that a downlink channel id is modified to 1, and then modification is effective in the (n + 1) th TTI in the downlink channel with the channel id being 1, that is, when the network device transmits downlink data in the (n + 1) th TTI, the network device performs downlink data transmission based on the downlink frequency adjustment parameter with the channel id being 1.
By adopting the technical scheme of the embodiment of the invention, the flexible switching of the uplink and downlink frequency parameters (including the switching of the uplink and downlink carrier frequency points) of the DCI at the TTI level is realized, and the base station can carry out scheduling switching of the frequency parameters in real time according to the real-time load condition of the carriers, so that the resource utilization is more sufficient, and the user experience is also improved.
Example two
The embodiment of the invention also provides a frequency point switching processing method which is applied to the terminal. Fig. 3 is a schematic flow chart of a frequency point switching processing method according to a second embodiment of the present invention; as shown in fig. 3, the method includes:
step 201: and the terminal receives a mapping set which is sent by the network equipment and contains the identifier and the frequency adjustment parameter.
Step 202: and the terminal receives downlink control information with a specific format sent by the network equipment, wherein the downlink control information with the specific format comprises a first identifier corresponding to a frequency adjustment parameter to be adjusted.
Step 203: and the terminal adjusts the frequency parameter from the specific TTI indicated by the downlink control information with the specific format based on the downlink control information with the specific format and the mapping set.
In this embodiment, the step of receiving, by the terminal, the mapping set including the identifier and the frequency adjustment parameter, sent by the network device includes: a terminal receives a mapping set which is sent by network equipment and contains an identifier and a frequency adjustment parameter through a specific signaling; wherein the specific signaling comprises: RRC CONNECTION SETUP signaling (RRC _ CONNECTION _ SETUP signaling) or RRC CONNECTION reconfiguration signaling (RRC _ CONNECTION _ reconfiguration signaling). And the terminal receives the mapping set and stores the mapping set.
Wherein, the mapping set comprises at least two groups of identifiers and mapping relation of frequency adjustment parameters. The identifier is used as an index identifier, is carried in the downlink control information with a specific format, and is used for indicating the channel frequency adjustment information to be adjusted of the PDSCH and/or the PUSCH, so that the terminal can conveniently search the mapping relation based on the identifier to obtain the frequency adjustment parameter to be adjusted corresponding to the identifier. The frequency adjustment parameter characterizes channel information to be adjusted, and the frequency adjustment parameter includes at least one of the following information: and the frequency point, the frequency and the frequency range represent the frequency point, the frequency or the frequency range after the terminal is adjusted. Examples of the mapping set may be shown in table 1 and table 2 in embodiment one, which is not described in detail in this embodiment. In practical applications, the network device configures initial channel information of uplink and downlink, and taking the schematic shown in table 1 or table 2 as an example, may pre-configure a frequency adjustment parameter (the frequency adjustment parameter may include an uplink frequency adjustment parameter and/or a downlink frequency adjustment parameter) corresponding to a channel id of 0 for data transmission.
In this embodiment, the adjusting the frequency parameter from the specific TTI indicated by the downlink control information with the specific format based on the downlink control information with the specific format and the mapping set includes: searching the mapping set based on a first identifier included in the downlink control information of the specific format, obtaining a first frequency adjustment parameter corresponding to the first identifier, and adjusting the frequency parameter from a specific TTI indicated by the downlink control information of the specific format based on the first frequency adjustment parameter.
Specifically, after the terminal obtains the downlink control information in the specific format, taking the downlink control information as DCI as an example, because the DCI includes a plurality of bits, at least one bit of the plurality of bits represents an identifier, for example, at least one bit represents that the channeld shown in table 1 is 0 or 1. Based on this, the terminal may obtain a corresponding first identifier according to a bit indicating the corresponding identifier in the DCI, for example, a channeld is 0 or 1, search for a stored mapping set based on the first identifier, and obtain a first frequency adjustment parameter corresponding to the first identifier as an adjusted frequency parameter.
In this embodiment, the adjusting the frequency parameter from the specific TTI indicated by the downlink control information with the specific format based on the downlink control information with the specific format and the mapping set includes: when the downlink control information with the specific format is used for scheduling downlink user data, controlling downlink user data corresponding to the next TTI adjacent to the TTI where the downlink control information with the specific format is located to transmit the downlink user data according to the adjusted downlink frequency parameter; and/or when the downlink control information with the specific format is used for scheduling uplink user data, controlling the uplink user data corresponding to the TTI with the downlink control information with the specific format, which is separated by four TTIs, to transmit the 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 of a downlink shared channel of a downlink TTI corresponding to a next TTI adjacent to a TTI in a transmission time interval in which the downlink control information in the specific format is located; and/or the downlink control information with the specific format is used for scheduling data transmission of an uplink shared channel of an uplink TTI corresponding to a TTI (transmission time interval) at which the downlink control information with the specific format is located, wherein the TTI is four TTIs apart. In this case, when the terminal receives DCI as the downlink control information, it can receive and/or transmit data based on the DCI instruction.
Specifically, the downlink control information may be DCI, and a new DCI format is configured in advance in this embodiment, where the DCI may include multiple bits, and at least one bit of the multiple bits represents an identifier, for example, one bit may represent that a channeld shown in table 1 is 0 or 1, and then both an uplink channel and a downlink channel corresponding to the determined channeld are adjusted according to the corresponding uplink frequency adjustment parameter and the corresponding downlink frequency adjustment parameter. For another example, the uplink channel id may be represented by two bits, where the first bit represents the uplink channel id, the second bit represents the downlink channel id, and both bits may be configured by configuration or only one bit thereof may be configured; when only one bit is configured, it indicates that only the uplink or downlink frequency parameters are adjusted. The timing relationship between the downlink control information (e.g. DCI) configured and the scheduled downlink shared channel in the embodiment of the present invention is: the downlink shared channel is positioned at the next downlink TTI of the TTI where the downlink control information is positioned; the timing relationship between the downlink control information (e.g., DCI) and the scheduled uplink shared channel is as follows: the uplink shared channel is located in the uplink TTI corresponding to the TTI of the downlink control information at intervals of four TTIs.
As an embodiment, when the DCI received by the terminal as the downlink control information is used to adjust the uplink frequency parameter, the terminal correspondingly transmits the uplink user data according to TTIs that are four TTIs apart from the TTI in which the DCI is located. For example, as shown in fig. 2, the PDCCH in the n-5 th TTI carries DCI as downlink control information, and the indication of the DCI is valid on the PUSCH corresponding to the n-th TTI in the uplink channel with the channeld being 0, that is, the n-5 th TTI is separated from the n-th TTI by 4 TTIs.
As another embodiment, when the DCI received by the terminal as the downlink control information is used to adjust the downlink frequency parameter, the terminal correspondingly receives downlink user data according to the next TTI adjacent to the TTI in which the DCI is located. For example, as shown in fig. 2, if the PDCCH in the nth TTI carries DCI as downlink control information indicating that the downlink channel id is modified to 1, the modification is valid in the (n + 1) th TTI in the downlink channel with the channel id being 1. In this embodiment, when the network device does not send DCI as the downlink control information, the terminal does not need to activate the receiving function, and does not need to receive corresponding user data, thereby saving power to a certain extent.
By adopting the technical scheme of the embodiment of the invention, the flexible switching of the uplink and downlink frequency parameters (including the switching of the uplink and downlink carrier frequency points) of the DCI at the TTI level is realized, and the base station can carry out scheduling switching of the frequency parameters in real time according to the real-time load condition of the carriers, so that the resource utilization is more sufficient, and the user experience is also improved.

In this embodiment, the first communication unit 31 is configured to send a mapping relationship between an identifier and a frequency adjustment parameter to a terminal through a specific signaling; wherein the specific signaling comprises: RRC CONNECTION SETUP signaling (RRC _ CONNECTION _ SETUP signaling) or RRC CONNECTION reconfiguration signaling (RRC _ CONNECTION _ reconfiguration signaling).
Wherein, the mapping set comprises at least two groups of identifiers and mapping relation of frequency adjustment parameters. The identifier is used as an index identifier, is carried in the downlink control information with a specific format, and is used for indicating the channel frequency adjustment information to be adjusted of the PDSCH and/or the PUSCH, so that the terminal can conveniently search the mapping relation based on the identifier to obtain the frequency adjustment parameter to be adjusted corresponding to the identifier. The frequency adjustment parameter characterizes channel information to be adjusted, and the frequency adjustment parameter includes at least one of the following information: and the frequency point, the frequency and the frequency range represent the frequency point, the frequency or the frequency range after the terminal is adjusted. Examples of the mapping set can be shown in table 1 and table 2, which are not described again in this embodiment. In practical application, the network device configures the initial channel information of the uplink and the downlink, and takes the schematic shown in table 1 or table 2 as an example, the frequency adjustment parameter corresponding to the channel id 0 may be configured in advance for data transmission.
In this embodiment, the downlink control information in the specific format is used to schedule downlink user data corresponding to a next TTI adjacent to a TTI in which the downlink control information in the specific format is located; and/or the downlink control information with the specific format is used for scheduling uplink user data corresponding to the TTI with the downlink control information with the specific format, which is separated by four TTIs.
