Description

Technical Field

[0002] The application of high-speed rail in NR (New Radio) system has brought new challenges. Due to the application requirements of higher frequency and higher speed, the Doppler frequency deviation is higher. Taking 3.6GHz frequency and 500km / h as an example, the maximum Doppler frequency deviation can reach 1667Hz. If higher frequency or higher speed is considered, the maximum Doppler frequency deviation that the terminal needs to handle will be higher. In addition, high-speed rail deployment usually adopts multi-cell merging to reduce frequent reselection / switching, but this deployment mode will have multi-cell confrontation scenarios (such as Figure 1 As shown in the figure, taking the collision of two cells as an example, the terminal needs to process two Doppler frequency deviations of the same size and opposite directions at the same time, which places higher requirements on the terminal capability.

[0215] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0216] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0217] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0218] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0219] In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B can also be determined according to A and / or other information.

[0220] like Figure 2 As shown, 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 the following:

[0221] Step 201, determining whether to enable Doppler frequency offset compensation or correction according to the first information;

[0222] Step 202: Perform Doppler frequency offset compensation or correction according to the second information.

[0223] In this way, the network device executes the method of the embodiment of the present invention. On the one hand, it can determine whether to start Doppler frequency offset compensation or correction according to the first information through 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. In this way, the Doppler frequency offset compensation or correction processing on the terminal side is reduced, achieving the purpose of improving the overall system performance of the network and ensuring the transmission quality.

[0224] Especially for the scenario where the terminal cannot handle the Doppler frequency deviation in high-speed scenarios, the transmission processing method of the embodiment of the present invention is executed on the network side, which weakens the role of the terminal in the Doppler frequency deviation compensation or correction processing, and avoids the terminal being restricted by the scenario and affecting the system performance and transmission quality.

[0225] Among them, if the network equipment such as the base station determines to start the Doppler frequency offset compensation or correction, it is to compensate or correct 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 transmission through the channel, the signal received by the terminal due to the Doppler frequency offset is F1+Δf1, Δf1 is the frequency offset value, and the base station reduces Δf1 by starting the Doppler frequency offset compensation or correction, so that the signal received by the terminal is less than F1+Δf1 or as close to F1 as possible.

[0226] In this embodiment, when the network device starts Doppler frequency offset compensation or correction, a target frequency offset for compensation or correction can be further determined, and frequency compensation or correction is performed according to the target frequency offset. Here, the target frequency offset can be determined for the terminal where the frequency offset occurs, or the first node (transmission reception point, TRP) to which the terminal belongs.

[0227] 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). RRH may also be referred to as a remote radio unit (RRU).

[0228] Optionally, the target frequency deviation is at least one of the following:

[0229] an average value of Doppler frequency shifts of uplink signals of all terminals in the first node to which the terminal belongs;

[0230] The maximum value of the Doppler frequency deviation of uplink signals of all terminals in the first node to which the terminal belongs;

[0231] The minimum value of the Doppler frequency shift of uplink signals of all terminals in the first node to which the terminal belongs;

[0232] The average value of the Doppler frequency deviation of some terminals in the first node to which the terminal belongs;

[0233] A minimum value of the Doppler frequency shift of some terminals in the first node to which the terminal belongs;

[0234] The Doppler frequency deviation of the uplink signal of any terminal.

[0235] The some terminals are terminals whose Doppler frequency deviation of uplink signals is greater than a certain value.

[0236] It should be known that, in this embodiment, enabling Doppler frequency offset compensation or correction may also be referred to as enabling Doppler frequency offset pre-compensation, or enabling Doppler frequency offset correction, or enabling Doppler frequency offset pre-correction.

[0237] Optionally, in this embodiment, the first information includes Doppler frequency deviation information of a signal received by the network device, and / or third information.

[0238] Here, the signal received by the network device refers to an uplink signal sent by a terminal and received by the network device, which may be from one terminal or multiple terminals. The third information is historical information of Doppler frequency offset compensation or correction.

[0239] Optionally, the third information includes at least one of the following:

[0240] Recording information of whether Doppler frequency offset compensation or correction is turned on within a first preset time period;

[0241] Whether the number of times Doppler frequency offset compensation or correction is turned on is greater than a second threshold within a second preset time period;

[0242] The speed state of the first terminal within a third preset time period, the speed state includes a high speed state, a low speed state or a medium speed state, wherein the first terminal is one or more terminals.

[0243] 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 the pre-set speed ranges of each state, the high speed state corresponds to the speed range (B-C), the low speed state corresponds to the speed range (0-A), and the medium speed state corresponds to the speed range (A-B). The first preset time, the second preset duration, and the third preset duration are pre-set, and two or three of them may be the same or different.

[0244] Thus, based on the Doppler frequency shift information of the signal received by the network device, and / or the third information, step 201 includes:

[0245] Determine whether the Doppler frequency deviation of the received signal is greater than a first threshold, and / or whether Doppler frequency deviation compensation or correction is turned on within the first preset time length, and / or whether the number of times Doppler frequency deviation compensation or correction is turned on within the second preset time length is greater than a second threshold, and / or the speed state of the first terminal within the third preset time length.

[0246] Here, the received signal is an uplink signal received by the network device and sent by the terminal.

[0247] Thus, if at least one of the following conditions is met, Doppler frequency offset compensation or correction is enabled:

[0248] The Doppler frequency deviation of the received signal is greater than a first threshold;

[0249] Enable Doppler frequency offset compensation or correction within a first preset time period;

[0250] The number of times Doppler frequency offset compensation or correction is started within the second preset time period is greater than a second threshold;

[0251] The speed state of the first terminal is a high speed state within the third preset time period.

[0252] In addition, in this embodiment, the second information is a frequency value used for Doppler frequency offset compensation or correction. Optionally, the second information is any one of the following:

[0253] An average value of the Doppler frequency deviations of uplink signals of all terminals in the first node;

[0254] The maximum value of the Doppler frequency deviation of the uplink signals of all terminals in the first node;

[0255] The minimum value of the Doppler frequency deviation of the uplink signals of all terminals in the first node;

[0256] An average value of the Doppler frequency shift of the uplink signal of the second terminal in the first node;

[0257] The minimum value of the Doppler frequency shift of the uplink signal of the second terminal in the first node;

[0258] A Doppler frequency deviation of an uplink signal of a third terminal;

[0259] The second terminal is a terminal whose Doppler frequency deviation of the uplink signal is greater than a third threshold; and the third terminal is any terminal.

[0260] Here, the first node may be a node to which the terminal to be compensated or corrected for Doppler frequency offset belongs. Of course, the terminal will track the Doppler frequency offset based on the first node.

[0261] However, in the case where multiple first nodes are merged, it is not possible to clearly know the first node to which the terminal to be compensated or corrected for Doppler frequency offset belongs. Therefore, optionally, in this embodiment, the method further includes:

[0262] In the event that a plurality of first nodes are merged, a second node is determined.

[0263] The second node may be: a cell, a TRP, or an RRH.

[0264] Optionally, the second node satisfies at least one of the following:

[0265] The quality of the received signal is greater than a fourth threshold;

[0266] The quality of the received signal is the highest among multiple candidate nodes;

[0267] The Doppler frequency deviation of the received signal is greater than a fifth threshold;

[0268] The Doppler frequency deviation of the received signal is the largest among multiple candidate nodes.

[0269] Here, the received signal is a signal received by the network device, and is an uplink signal sent by the terminal. The multiple candidate nodes may be multiple merged first nodes, or may be first nodes that meet a preset condition among the multiple merged first nodes.

[0270] In this way, the second node is the first node whose received signal quality is greater than the fourth threshold; or the first node whose received signal quality is the largest among the multiple merged first nodes; or the first node whose received signal Doppler frequency deviation is greater than the fifth threshold; or the first node whose received signal Doppler frequency deviation is the largest among the multiple merged first nodes; or the first node whose received signal quality is greater than the fourth threshold and whose Doppler frequency deviation is greater than the fifth threshold; or the first node whose received signal Doppler frequency deviation is the largest among the first nodes whose received signal quality is greater than the fourth threshold; or the first node whose received signal quality is the largest among the first nodes whose received signal Doppler frequency deviation is greater than the fifth threshold. Among them, the first node whose received signal quality is greater than the fourth threshold and whose Doppler frequency deviation is greater than the fifth threshold may be the first node whose Doppler frequency deviation is greater than the fifth threshold among the first nodes whose received signal quality is greater than the fourth threshold; or may be the first node whose received signal quality is greater than the fourth threshold among the first nodes whose received signal Doppler frequency deviation is greater than the fifth threshold.

[0271] In this embodiment, optionally, the method further includes:

[0272] A first signaling is sent to the terminal, where the first signaling is used to inform the terminal whether the network device turns on Doppler frequency offset compensation or correction.

[0273] That is, the network device explicitly notifies the terminal through signaling whether the network device turns on Doppler frequency offset compensation or correction. The first signaling may be RRC signaling, or a broadcast message.

[0274] The terminal can also implicitly estimate whether the network device has enabled Doppler frequency offset compensation or correction based on the Doppler frequency offset of the downlink signal sent by the network device. Specifically, the terminal determines that it is in a high-speed scene, or the signaling of the network device notifies the terminal that it is in a high-speed scene. If the Doppler frequency offset estimated by the terminal based on the downlink signal is small (for example, below a certain threshold), it is considered that the network device has enabled Doppler frequency offset compensation or correction, otherwise it is not enabled.

[0275] In addition, optionally, in this embodiment, the second information includes a transmission configuration indication state identifier TCI stateID.

[0276] Here, the TCI state ID may indicate the first node. In this way, the network device executes step 202 to perform Doppler frequency offset compensation or correction on the first node.

[0277] Optionally, the method further comprises:

[0278] Sending second information to the terminal;

[0279] The second information is sent in at least one of the following ways:

[0280] Radio Resource Control RRC signaling;

[0281] Media access control unit MAC CE;

[0282] Downlink control signaling DCI.

[0283] In this way, the network device can notify the terminal to perform frequency tracking or frequency estimation or Doppler frequency deviation estimation based on the first node, such as a cell or TRP or RRH, through the second information including the TCI state ID.

[0284] Optionally, a TCI state ID is indicated by N bits; or, a corresponding TCI state ID is indicated by each of M bits; wherein N and M are integers greater than or equal to 1.

[0285] Here, the second information indicates a TCI state ID through N bits, such as when N=2, "00" indicates TCI state ID0, and "01" indicates TCI state ID1. Each bit in the M bits indicates the corresponding TCI state ID, such as when M=2, "01" indicates TCI state ID0 and TCI state ID1.

[0286] Specifically, when the second information is sent down through MAC CE, MAC CE indicates a TCI state ID through N1 (i.e., N=N1) bits; or, each bit in M1 (i.e., M=M1) bits indicates a corresponding TCI state ID. When the second information is sent down through DCI, DCI indicates a TCI state ID through N2 (i.e., N=N2) bits; or, each bit in M2 (i.e., M=M2) bits indicates a corresponding TCI state ID.

[0287] Optionally, when the second information is sent down through MAC CE, the MAC CE is identified by LCID.

[0288] That is, the MAC CE transmitting the second information is identified by the locale identifier LCID.

[0289] In summary, the method of the embodiment of the present invention is executed by the network device, and can determine whether to enable Doppler frequency offset compensation or correction according to the first information; and can perform Doppler frequency offset compensation or correction according to the second information. In this way, the Doppler frequency offset compensation or correction processing on the terminal side is reduced, and the purpose of improving the overall system performance of the network and ensuring the transmission quality is achieved.
