Description

Uplink transmission processing method, terminal and base station
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to an uplink transmission processing method, a terminal and a base station.
Background
In recent years, wireless communication technology has rapidly progressed, and modern society has entered the information age. None of the various communication technologies is moving towards the goal of "high rate, low latency", and increasingly stringent requirements for latency are also explicitly written into the design criteria of the various communication technologies. The 3GPP has raised a stand-off for "reduced latency technology" that defines a "short transmission time interval" (short Transmission Time Interval, sTTI) for carrying low latency traffic in order to distinguish from legacy TTIs. The uplink defines two different length sTTI, 7 symbol sTTI and 2 (3) symbol sTTI, respectively. For a 7-symbol sTTI, an uplink demodulation reference signal (Demodulation Reference Signal, DMRS) scheme of legacy TTI may be used, and for an uplink DMRS scheme of a 2 (3) symbol sTTI, attention is paid more and more.
Fig. 1 is a schematic diagram of an uplink 2 (3) symbol sTTI frame structure, and as shown in fig. 1, the uplink 2 (3) symbol sTTI structure is fixed in {3,2,2,2,2,3} format. Under the prior art condition, the uplink DMRS of the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) in the legacy TTI fixedly occupies the fourth symbol of each time slot, if the short physical uplink shared channel (short Physical Uplink Shared Channel, sps) of the uplink 2 (3) symbol sttti is used for transmission, the configuration positions of the scheduled uplink sttti and the uplink DMRS are simultaneously configured in the uplink scheduling instruction, and the configuration of the uplink DMRS position needs to be performed through the configuration information every time the uplink transmission is performed, so that the configuration information overhead of the uplink DMRS is larger.

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 2 is a flow chart of an uplink transmission processing method according to an embodiment of the present invention, as shown in fig. 2, where the embodiment provides an uplink transmission processing method, including:
s101, receiving a preset RRC signaling message sent by a base station, wherein the preset RRC signaling message carries first indication information, and the first indication information is used for indicating a target uplink DMRS position configuration format called before receiving a next preset RRC signaling message;
specifically, the base station sends a preset RRC signaling message to the terminal, where the preset RRC signaling message carries the first indication information, where the first indication information is used to indicate a target uplink DMRS location configuration format that is called by the terminal before receiving a next preset RRC signaling message; and the terminal receives the preset RRC signaling message. It should be noted that, the first indication information may be set to 1 bit, and may be specifically set and adjusted according to actual situations, which is not specifically limited herein; the preset RRC signaling message may be sent once every preset period, and the terminal may use the target uplink DMRS location configuration format indicated by the first indication information in a period after receiving the preset RRC signaling message, where the period may be set as a plurality of radio frames; of course, the preset RRC signaling message may also be sent in other sending manners, and specifically may be adjusted according to actual situations, which is not limited herein. For example, the base station 0:00 sends the preset RRC signaling message to the terminal for the first time, and the terminal uses the target uplink DMRS location configuration format indicated by the first indication information after receiving the preset RRC signaling message sent by the base station for the first time and in a period of time before receiving the preset RRC signaling message sent by the base station for the second time.
S102, receiving an uplink scheduling instruction sent by a base station, wherein the uplink scheduling instruction carries information of scheduled uplink sTTI;
specifically, the terminal receives an uplink scheduling instruction sent by the base station, where the uplink scheduling instruction carries information of the scheduled uplink sTTI, and the uplink scheduling instruction may also carry other information, specifically may be adjusted according to an actual situation, and is not specifically limited herein.
S103, determining a target configuration position of the uplink DMRS according to the target uplink DMRS position configuration format and the information of the scheduled uplink sTTI;
specifically, the terminal determines the target uplink DMRS position configuration format according to the first indication information, and then uses the uplink DMRS predefined configuration position corresponding to each sTTI of the target uplink DMRS position configuration format in the target uplink DMRS position configuration format as the target configuration position of the uplink DMRS according to the scheduled uplink sTTI information, the target uplink DMRS position configuration format, and the uplink DMRS predefined configuration position corresponding to each sTTI of the target uplink DMRS position configuration format.
And S104, carrying out uplink transmission according to the target configuration position of the uplink DMRS and the scheduled uplink sTTI information.
Specifically, the terminal performs uplink DMRS transmission according to the target configuration position of the uplink DMRS, and simultaneously, uplink data transmission is carried out according to the scheduled uplink sTTI information.
For example, DMRS location formats are defined for each sTTI in the prior art, as shown in table 1. For a 2 (3) symbol sTTI, in order to avoid collision between data symbols of the SPUSCH of different sTTI and DMRS symbols, a fixed symbol position is predefined in each sTTI, and the symbol position can be configured as a DMRS symbol; and can be used as data symbols when the symbol position is not configured as a DMRS symbol, other symbols without predefined can only be fixed as data symbols. Therefore, the existing DMRS location formats may be divided into two preset DMRS location configuration formats based on the uplink DMRS location formats defined in table 1:
a first predetermined uplink DMRS position configuration format (Set 0) as shown in fig. 3, where Symbol positions with shaded marks in fig. 3 are DMRS predefined positions, uplink DMRS predefined positions for sTTI # 0-5 are Symbol #0, symbol #3, symbol #5, symbol #7, symbol #9, symbol #11, respectively, where Symbol #0, symbol #3, symbol #5, symbol #7, symbol #9, symbol #11 can be used as the uplink DMRS configuration position, configured as DMRS symbols, and when not configured as DMRS symbols, can be used as data symbols, and Symbol #1, symbol #2, symbol #4, symbol #6, symbol #8, symbol #10, symbol #12, symbol #13 can only be fixed as data symbols.
Another type of configuration format (Set 1) is a second preset uplink DMRS position shown in fig. 4, the Symbol positions with shaded marks in fig. 4 are uplink DMRS predefined configuration positions, and the uplink DMRS predefined configuration positions of stti#0 to 5 are symbol#2, respectively,
Symbol #4, symbol #6, symbol #8, symbol #10, symbol #11, wherein Symbol #2, symbol #4, symbol #6, symbol #8, symbol #10, symbol #11 may be used as the upstream DMRS configuration location, configured as a DMRS Symbol, and Symbol #0, symbol #1, symbol #3, symbol #5, symbol #7, symbol #9, symbol #12, symbol #13 may only be fixed as data symbols when not configured as a DMRS Symbol.
Table 2 is a correspondence relationship among the information of the scheduled uplink sTTI, the target uplink DMRS position configuration format, and the configuration position of the uplink DMRS, as shown in table 2, where the first indication information indicates the uplink DMRS position configuration format with an indication bit of 1 bit. The first indication information carried in the preset RRC signaling message received by the terminal is '0', the terminal determines that the position configuration format of the target uplink DMRS is 'Set 0' (shown in figure 3) according to the first indication information, the terminal receives an uplink scheduling instruction sent by the base station, and determines that the scheduled sTTI is sTTI #0 according to the information of the scheduled uplink sTTI carried by the uplink scheduling instruction; and the terminal determines that the uplink DMRS target configuration position corresponding to the scheduled uplink sTTI (stti#0) is symbol#0 according to the first indication information (0) and the scheduled uplink sTTI (stti#0) and the lookup table 2.

According to the uplink transmission processing method provided by the embodiment of the invention, the target configuration position of the uplink DMRS is determined according to the target uplink DMRS position configuration format indicated by the first indication information carried in the preset RRC signaling message sent by the base station and the scheduled uplink sTTI information carried in the uplink scheduling instruction, and uplink transmission is performed according to the target configuration position of the uplink DMRS and the scheduled uplink sTTI information, so that the cost of the uplink DMRS configuration information is reduced.
On the basis of the above embodiment, further, the scheduled uplink sTTI is a non-fixed sTTI corresponding to the target uplink DMRS location configuration format;
correspondingly, the uplink scheduling instruction also carries second indication information, wherein the second indication information is used for indicating the position configuration type of the uplink DMRS of the non-fixed sTTI;
accordingly, the method further comprises:
and determining the target configuration position of the uplink DMRS according to the information of the scheduled uplink sTTI, the target uplink DMRS position configuration format and the position configuration type of the uplink DMRS.
Specifically, when the base station determines that the scheduled uplink sTTI is a non-fixed sTTI corresponding to the target uplink DMRS location configuration format according to the first indication information carried in the preset RRC signaling message and the information of the scheduled uplink sTTI, the base station may further carry second indication information in the uplink scheduling instruction, where the second indication information is used to indicate a location configuration type of the uplink DMRS, as shown in table 3, where the location configuration type of the uplink DMRS includes: the second indication information may also be set to 1 bit, with an uplink DMRS predefined configuration position corresponding to a next sTTI adjacent to the scheduled uplink sTTI being a target configuration position (Mode 0) of the uplink DMRS, and with an uplink DMRS predefined configuration position corresponding to a previous sTTI adjacent to the scheduled uplink sTTI being a target configuration position (Mode 1) of the uplink DMRS. It should be noted that, when the target uplink DMRS position configuration format is the first preset uplink DMRS position configuration format (Set 0), the position configuration type of the uplink DMRS is Mode0; when the target uplink DMRS position configuration format is the second preset uplink DMRS position configuration format (Set 1), the position configuration type of the uplink DMRS is Mode1.
For example, referring to fig. 3, when the target uplink DMRS position configuration format is the first preset position configuration format and the scheduled sTTI is stti#0, stti#2, or stti#5, the corresponding uplink DMRS target configuration positions can only adopt the DMRS predefined positions corresponding to each other, that is, symbol#0, symbol#5, symbol#11, respectively, so stti#0, stti#2, and stti#5 are used as the fixed sTTI of the first preset position configuration format, and the remaining stti#1, stti#3, and stti#4 are non-fixed sTTI of the first preset position configuration format. Further, referring to fig. 4, when the target uplink DMRS position configuration format is the second preset position configuration format and the scheduled sTTI is stti#0, stti#3 or stti#5, the corresponding uplink DMRS target configuration positions can only adopt the corresponding uplink DMRS predefined configuration positions, i.e., symbol#0, symbol#5, symbol#11, respectively, so stti#0, stti#3 and stti#5 are used as the fixed sTTI of the second preset position configuration format, and the remaining stti#1, stti#2 and stti#4 are non-fixed sTTI of the second preset position configuration format. For the non-fixed sTTI, the first indication information is used for indicating the position configuration format of the target uplink DMRS, the second indication information is used for indicating the position configuration type of the target uplink DMRS, and the target configuration position of the uplink DMRS is determined according to the information of the scheduled uplink sTTI, the position configuration format of the target uplink DMRS indicated by the first indication information and the position configuration type of the uplink DMRS indicated by the second indication information.
The first indication information carried in the preset RRC signaling message received by the terminal is '0', the terminal determines that the preset uplink DMRS position configuration format is 'Set 0' (shown in fig. 3) according to the first indication information, the terminal receives an uplink scheduling instruction sent by the base station, determines that the scheduled sTTI is sTTI#1 according to the information of the scheduled uplink sTTI carried by the uplink scheduling instruction, and the second indication information is 0; the terminal searches in fig. 3 for an uplink DMRS predefined configuration position "symbol#5" corresponding to an stti#2 adjacent to the stti#1 as a target configuration position of the uplink DMRS, and then the terminal transmits uplink data at data Symbol positions "symbol#3" and "symbol#4" of the stti#1, and transmits uplink DMRS at an uplink DMRS predefined configuration position "symbol#5" of the stti#2. At this time, the stti#1 may be used as a data Symbol position to transmit data, where stti#1 and stti#2 share "symbol#5" to transmit an uplink DMRS, thereby reducing the overhead of the uplink DMRS.
