Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
In addition, the terms "system" and "network" are often used interchangeably herein.
In the embodiments provided herein, it should be understood that "B corresponding to a" means that B is associated with a from which B can be determined. It should also be understood that determining B from a does not mean determining B from a alone, but may be determined from a and/or other information.
As shown in fig. 2, a transmission processing method according to an embodiment of the present invention is applied to a network device, and the method includes at least one of:
step 201, determining whether to start Doppler frequency offset compensation or correction according to the first information;
and 202, performing Doppler frequency offset compensation or correction according to the second information.
Thus, when the network device executes the method of the embodiment of the present invention, on one hand, it can determine whether to start doppler frequency offset compensation or correction according to the first information in step 201; on the other hand, the network device can perform doppler frequency offset compensation or correction according to the second information through step 202. Therefore, Doppler frequency offset compensation or correction processing at the terminal side is reduced, and the purposes of improving the overall system performance of the network and ensuring the transmission quality are achieved.
Particularly, in a scenario in which the terminal cannot process the doppler frequency offset in a high-speed scenario, the transmission processing method of the embodiment of the present invention is executed on the network side, which weakens the effect of the terminal in the doppler frequency offset compensation or correction processing, and avoids the influence of the terminal on the system performance and the transmission quality due to the limitation of the scenario.
If the network device, such as a base station, determines to start doppler frequency offset compensation or correction, the network device compensates or corrects the frequency offset of the signal received by the terminal and sent by the base station. For example, the operating frequency of the base station is F1, and after the signal is transmitted through the channel, since the signal received by the doppler frequency offset terminal is F1+ Δ F1, and Δ F1 is the frequency offset value, the base station reduces Δ F1 by starting doppler frequency offset compensation or correction and performing processing, so that the signal received by the terminal is smaller than F1+ Δ F1 or as close to F1 as possible.
In this embodiment, when the network device starts doppler frequency offset compensation or correction, the target frequency offset for compensation or correction may be further determined, and frequency compensation or correction may be performed according to the target frequency offset. Here, the target frequency offset may be determined for a terminal where the frequency offset occurs or a first node (TRP) to which the terminal belongs.
The first node may be a transmission node or a network node. Specifically, the first node is: a cell, a Transmission Reception Point (TRP), or a Remote Radio Head (RRH). The RRH may also be referred to as a Remote Radio Unit (RRU).
Optionally, the target frequency offset is at least one of:
the average value of the Doppler frequency offsets of uplink signals of all terminals in a first node to which the terminal belongs;
the maximum value of the Doppler frequency offset of uplink signals of all terminals in a first node to which the terminal belongs;
the minimum value of the Doppler frequency offset of uplink signals of all terminals in a first node to which the terminal belongs;
the average value of the Doppler frequency offset of part of terminals in a first node to which the terminal belongs;
the minimum value of Doppler frequency offset of part of terminals in a first node to which the terminal belongs;
the Doppler frequency offset of the uplink signal of any terminal.
And the part of terminals are terminals of which the Doppler frequency offset of the uplink signals is greater than a certain value.
It should be appreciated that, in this embodiment, turning on the doppler shift compensation or correction may also be referred to as turning on the doppler shift pre-compensation, or turning on the doppler shift rectification, or turning on the doppler shift pre-rectification.
Optionally, in this embodiment, the first information includes doppler frequency offset information of a signal received by the network device, and/or third information.
Here, the network device received signal refers to an uplink signal sent by a terminal and received by the network device, and may be from one terminal or multiple terminals. And the third information is history information of doppler frequency offset compensation or correction.
Optionally, the third information includes at least one of:
within a first preset time length, compensating or correcting Doppler frequency offset to record information whether the mobile terminal is started or not;
whether the starting times of Doppler frequency offset compensation or correction is greater than a second threshold value within a second preset time length or not;
and within a third preset time period, the speed state of the first terminal comprises a high speed state, a low speed state or a medium speed state, wherein the first terminal is one or more terminals.
Here, if the first terminal is a plurality of terminals, the first terminal is a group of terminals belonging to the same first node. The speed state of the first terminal is determined according to preset speed ranges of various states, wherein the high speed state corresponds to the speed ranges (B-C), the low speed state corresponds to the speed ranges (0-A), and the medium speed state corresponds to the speed ranges (A-B). The first preset time, the second preset time and the third preset time are preset, and the two or the three may be the same or different.
Thus, based on the doppler shift information of the signal received by the network device, and/or the third information, step 201 includes:
judging whether the Doppler frequency offset of the received signal is greater than a first threshold value, and/or whether Doppler frequency offset compensation or correction is started within the first preset time length, and/or whether the frequency of starting Doppler frequency offset compensation or correction within the second preset time length is greater than a second threshold value, and/or the speed state of the first terminal within the third preset time length.
Here, the received signal is an uplink signal transmitted by the terminal and received by the network device.
Thus, if at least one of the following conditions is satisfied, doppler frequency offset compensation or correction is turned on:
the Doppler frequency offset of the received signal is larger than a first threshold value;
starting Doppler frequency offset compensation or correction within a first preset time length;
the frequency of starting Doppler frequency offset compensation or correction in a second preset time length is larger than a second threshold value;
and the speed state of the first terminal is a high-speed state within a third preset time period.
In addition, in this embodiment, the second information is a frequency value used for doppler frequency offset compensation or correction, and optionally, the second information is any one of:
the average value of the Doppler frequency offsets of uplink signals of all terminals in the first node;
the maximum value of the Doppler frequency offset of uplink signals of all terminals in the first node;
the minimum value of the Doppler frequency offset of uplink signals of all terminals in the first node;
an average value of Doppler frequency offset of an uplink signal of a second terminal in the first node;

the second terminal is a terminal of which the Doppler frequency offset of the uplink signal is greater than a third threshold value; the third terminal is any terminal.
Here, the first node may be a node to which a terminal to be subjected to doppler frequency offset compensation or correction belongs. Of course, the terminal tracks the doppler shift based on the first node.
However, in the case where a plurality of first nodes are combined, the first node to which the terminal to be subjected to doppler frequency offset compensation or correction belongs cannot be clearly known. Therefore, optionally, in this embodiment, the method further comprises:
in the event that a plurality of first node merges occurs, a second node is determined.
Wherein the second node may be: cell, TRP, or RRH.
Optionally, the second node satisfies at least one of:

the quality of the received signal is greatest among the plurality of candidate nodes;
the Doppler frequency offset of the received signal is larger than a fifth threshold value;

Here, the received signal is a signal received by the network device and is an uplink signal transmitted by the terminal. The candidate nodes may be a plurality of merged first nodes, or may be first nodes satisfying a predetermined condition among the plurality of merged first nodes.
Thus, the second node is the first node whose received signal quality is greater than the fourth threshold; or, the first node with the highest quality of the received signals in the combined plurality of first nodes; or the Doppler frequency offset of the received signal is larger than the first node of the fifth threshold value; or, the first node with the largest Doppler frequency offset of the received signals in the combined plurality of first nodes; or, the quality of the received signal is greater than the fourth threshold, and the doppler frequency offset is greater than the first node of the fifth threshold; or, the first node with the largest Doppler frequency offset of the received signal in the first nodes with the quality of the received signal larger than the fourth threshold; or, the first node with the largest quality of the received signal is the first node with the doppler frequency offset of the received signal larger than the fifth threshold. The first node where the quality of the received signal is greater than the fourth threshold and the doppler frequency offset is greater than the fifth threshold may be the first node where the determined doppler frequency offset is greater than the fifth threshold in the first nodes where the quality of the received signal is greater than the fourth threshold; the first node of which the quality of the received signal is greater than the fourth threshold value can be determined in the first node of which the Doppler frequency offset of the received signal is greater than the fifth threshold value.
In this embodiment, optionally, the method further includes:
and sending a first signaling to the terminal, wherein the first signaling is used for informing the terminal whether the network equipment starts Doppler frequency offset compensation or correction.
That is, the network device explicitly notifies the terminal through the signaling whether the network device starts the doppler frequency offset compensation or correction. The first signaling may be RRC signaling, or a broadcast message.
And the terminal can also implicitly estimate whether the network equipment starts the Doppler frequency offset compensation or correction based on the Doppler frequency offset of the downlink signal sent by the network equipment. Specifically, the terminal determines that the terminal is in a high-speed scene, or a signaling of the network device informs the terminal that the terminal is in the high-speed scene, and if the doppler frequency offset estimated by the terminal based on the downlink signal is small (for example, lower than a certain threshold), the network device is considered to be on doppler frequency offset compensation or correction, otherwise, the doppler frequency offset compensation or correction is not on.
Further, optionally, in this embodiment, the second information includes a transmission configuration indication status identifier TCI state ID.
Here, the TCI state ID may indicate the first node. Thus, the network device performs step 202 to perform doppler frequency offset compensation or correction for the first node.
Optionally, the method further comprises:
sending the second information to the terminal;
wherein the second information is issued in at least one of the following ways:
radio resource control, RRC, signaling;
a media access control unit (MAC CE);
and downlink control signaling DCI.
In this way, the network device can inform the terminal to perform frequency tracking or frequency estimation or doppler frequency offset estimation based on the first node, such as a cell or a TRP or an RRH, through the second information including the TCI state ID.
Optionally, one TCI state ID is indicated by N bits; or, a corresponding TCI state ID is indicated by each of the M bits; wherein N and M are integers greater than or equal to 1.
Here, the second information indicates one TCI state ID by N bits, for example, "00" indicates TCI state ID0 and "01" indicates TCI state ID1 when N is 2. A corresponding TCI state ID is indicated by each of the M bits, and when M is 2, "01" indicates TCI state ID0 and TCI state ID 1.
Specifically, when the second information is issued by the MAC CE, the MAC CE indicates a TCI state ID by N1 (i.e., N1) bits; alternatively, the corresponding TCI state ID is indicated by each of M1 (i.e., M1) bits. When the second information is issued through DCI, the DCI indicates one TCI state ID through N2 (i.e., N2) bits; alternatively, the corresponding TCI state ID is indicated by each bit of M2 (i.e., M2) bits.
Optionally, when the second information is issued by the MAC CE, the MAC CE identifies through the LCID.
That is, the MAC CE transmitting the second information is identified by the area setting identifier LCID.
To sum up, the method of the embodiment of the present invention is executed by a network device, and can determine whether to start doppler frequency offset compensation or correction according to the first information; doppler frequency offset compensation or correction can be performed according to the second information.
