Description

Method and device for transmitting physical uplink shared channel Technical field

The present invention relates to the field of communications, and in particular to a method and an apparatus for transmitting a physical uplink shared channel.

Background technique

A radio frame in a Long Term Evolution (LTE) system includes a Frequency Division Duplex (FDD) mode and a Time Division Duplex (TDD) mode. Frame structure. The frame structure of the FDD mode, as shown in Figure 1, a 10 msec (ms) radio frame consists of twenty slots of length 0.5 ms, numbered 0-19, and slots 2i and 2i+1. A subframe of length 1 ms. The frame structure of the TDD mode, as shown in FIG. 2, a 10 ms radio frame is composed of two half frames of 5 ms length, one field includes five subframes of length 1 ms, and subframe i is defined as Two time slots 2i and 2i+1 of length 0.5 ms.

In the above two frame structures, for a standard Cyclic Prefix (Normal CP), one slot contains seven symbols with a length of 66.7 microseconds (us), where the CP length of the first symbol is 5.21us, the CP length of the remaining 6 symbols is 4.69us; for the Extended Cyclic Prefix (Extended Cyclic Prefix, for short), one slot contains 6 symbols, and the CP length of all symbols is 16.67us. The time unit T _{s is} defined as T _s =1/(15000×2048) seconds. The supported uplink and downlink configurations are shown in Table 1 below. For each subframe in a radio frame, “D” indicates dedicated to downlink transmission. Subframe, "U" indicates a subframe dedicated for uplink transmission, "S" indicates Downlink Pilot TimeSlot for downlink (SW), guard interval (GP, for short), and uplink pilot. The special subframes of the three domains of Uplink Pilot TimeSlot (referred to as UpPTS), the lengths of DwPTS and UpPTS are shown in Table 2. Their lengths are subject to DwPTS, and the total length of GP and UpPTS is 30720·T _s =1ms. . Each subframe i is represented by 2 slots 2i and 2i+1, each slot having a length of T _slot = 15360 · T _s = 0.5 ms.

LTE TDD supports 5ms and 10ms uplink and downlink switching cycles. If the downlink to uplink transition point period is 5 ms, the special subframe will exist in two fields; if the downlink to uplink transition point period is 10 ms, the special subframe exists only in the first field. Subframe 0 and subframe 5 and DwPTS are always used for downlink transmission. The UpPTS and the subframe immediately following the special subframe are dedicated to the uplink transmission.

Table 2: Special Subframe Configuration (DwPTS/GP/UpPTS Length)

In LTE, the physical downlink control channel PDCCH is used to carry uplink and downlink scheduling information, and uplink power control information. The Downlink Control Information (DCI) format is divided into DCI formats 0, 1, 1A, 1B, 1C, 1D, 2, 2A, 3, 3A, and the like. The base station (e-Node-B, referred to as eNB for short) can configure the terminal equipment (User Equipment, UE for short) through the downlink control information, or The end device accepts the configuration of higher layers, also known as configuring the UE through higher layer signaling.

Table 3: Special Subframe Configuration (DwPTS/GP/UpPTS Length)

The LTE-Advanced (LTE-A) system is a next-generation evolution system of the LTE system. In the related art, the physical shared channel (Physical Shared Channel, PUSCH for short) is not supported on the UpPTS symbol. This is because there are only 2 UpPTS symbols before LTE-A Release 13, as shown in Table 2. In the LTE-A Release 13 phase, in the scenario of configuring MIMO (Full Dimension-MIMO, FD-MIMO for short) or MIMO (Massive-MIMO) for a large number of antennas, the number of users increases and the TDD channel interacts with each other. The requirement for the measurement of the Sounding Reference Signal (SRS) is increased, and it is determined that the multiplexing capacity of the SRS is enhanced by increasing the number of UpPTS symbols in the special subframe of the TDD. The number of newly added UpPTS symbols X is 2 or 4, and is notified to the terminal by user-specific (UE-specific) signaling, as shown in Table 3. Therefore, the number of UpPTS symbols in a special subframe can be up to six. In order to make better use of the uplink spectrum resources, it is necessary to study how to transmit the PUSCH on the UpPTS.

For the related art, the problem that the physical uplink shared channel PUSCH is transmitted on the uplink pilot time slot UpPTS is not supported in the time division duplex TDD system, and an effective solution has not been proposed.

The embodiments of the present invention are exemplified in the following with reference to specific embodiments.

Alternative embodiment 1

In an optional embodiment, the symbol configuration for transmitting the PUSCH in the UpPTS is mainly fixed, and only the number of symbols is notified.

The application scenario of this embodiment is a time division duplex (TDD) system. The uplink-downlink configuration is set to 3 according to the configuration information shown in Table 1, the downlink subframe uses a regular cyclic prefix, and the uplink subframe uses a regular cyclic prefix.

The terminal sends a physical uplink shared channel (PUSCH) to the base station on the time-frequency resource corresponding to the uplink pilot time slot in the special subframe of the radio frame, and the terminal is adjacent to the guard interval (GP) in the special subframe. The physical uplink shared channel is transmitted on the uplink pilot time slot of the time domain OFDM symbol length, where the value of Y is configured by the base station through user-specific high layer signaling, as shown in Table 4, assuming that the uplink pilot time slot has a total of N The length of the symbol, N is an integer between 1 and 6, and N is composed of a sum of three parts. The length of a part of the OFDM symbol is determined by the special subframe configuration, which is a conventional OFDM symbol that can be used for SRS transmission, and the second part is X. The newly added OFDM symbol for SRS transmission, the third part is the newly added OFDM symbol for PUSCH transmission, wherein the OFDM symbol used for PUSCH transmission is the most adjacent to the guard interval in the special subframe, and secondly In the OFDM symbol transmitted by the SRS, the OFDM symbol configured by the special subframe is closest to the subframe 2 in the radio frame. 23A and 23B are schematic diagrams of time domain locations for transmitting a PUSCH on an UpPTS, where a special subframe configuration is 0, and in FIG. 23A, X=2, Y=2, indicating that the guard interval (GP) is closest to the special subframe. Two consecutive OFDM symbols are used to transmit the PUSCH. In FIG. 23B, X=0, Y=4, indicating that four consecutive OFDM symbols closest to the guard interval (GP) in the special subframe are used to transmit the PUSCH.

Table 4: Special Subframe Configuration (DwPTS/GP/UpPTS Length)

It should be noted that if the terminal does not receive the configuration of Y, then Y=0 is considered, and the Y value is not configured to make the length of the downlink pilot slot, the guard interval, the length of the uplink pilot slot, and more than one subframe. Length, otherwise Y=0. Alternative embodiment 2

In an optional embodiment, the symbol configuration of the PUSCH is sent in the UpPTS, and the location is notified by using a bitmap.

The application scenario of this embodiment is a time division duplex (TDD) system. The uplink/downlink configuration is set to 3 according to the configuration information shown in Table 1, the downlink subframe uses a regular cyclic prefix, and the uplink subframe uses a regular cyclic prefix.

The terminal sends a physical uplink shared channel (PUSCH) to the base station on the time-frequency resource corresponding to the uplink pilot time slot in the special subframe of the radio frame, and the base station uses the uplink pilot time slot in the user-specific high-layer signaling. The time domain OFDM symbol position of the PUSCH is transmitted to the terminal, and the base station allocates the time domain OFDM symbol position for transmitting the PUSCH in the uplink pilot time slot to the terminal by means of bit mapping or bitmap. As shown in Table 3, the terminal determines the total number of OFDM symbols N in the uplink pilot time slot according to the special subframe configuration and the value of X, where N is an integer between 1 and 6, including 1 to 6, and the terminal is based on the base station. The configured bitmap determines the OFDM symbol location used to transmit the PUSCH in the uplink pilot slot. It is assumed that when the special subframe configuration is 0, the conventional OFDM symbol that can be used to transmit the SRS is one, and the X configuration of the terminal received by the terminal is 4, that is, the uplink pilot time slot has a total length of 5 OFDM symbols, and 5 Although OFDM symbols can be used to transmit SRS, not all OFDM are actually used to transmit SRS. Assuming that only one symbol is used to transmit SRS, the remaining 4 symbol base stations can be configured for the user to transmit PUSCH. For example, as shown in FIG. 24, the terminal learns the symbols used to transmit the SRS according to the configuration of the base station, and the remaining 4 symbols are used to transmit the PUSCH.

Alternative embodiment 3

In an optional embodiment, the demodulation pilot configuration for transmitting the PUSCH in the UpPTS is mainly

The terminal determines, according to configuration information of the base station or a predefined criterion, a demodulation pilot resource configuration of the PUSCH transmitted in the uplink pilot time slot, including demodulating the OFDM symbol position of the pilot in the uplink pilot time slot.

The first method is to determine, according to configuration information of the base station, the OFDM symbol of the demodulation pilot in the uplink pilot time slot, and optionally, the base station uses the uplink specific pilot time slot to send the PUSCH by using user-specific high layer signaling. The OFDM symbol position is notified to the terminal. Optionally, the base station notifies the terminal of the OFDM symbol position used for transmitting the PUSCH in the uplink time slot by means of a bit mapping or a bitmap. The OFDM symbol used to transmit the PUSCH may or may not include demodulation pilot symbols associated with the PUSCH. The manner of the bit mapping or the bitmap is that, if the uplink pilot slot includes a total of N OFDM symbols, the base station uses N bits to indicate whether the N OFDM symbols are used by the terminal to send the PUSCH, for example, N=5. If the configuration signaling of the base station received by the terminal is 01011, the base station configures the second, fourth, and fifth symbols from the left to the right in the uplink pilot time slot for transmitting the PUSCH, and the terminal is on the symbols. Send PUSCH.

The second mode is determined according to a predefined criterion. For example, in the first embodiment, since the time domain resource used for transmitting the PUSCH is always the closest to the guard interval (GP) in the special subframe, the closest guard interval may be used. (GP) The one symbol is used as the OFDM symbol in which the demodulation pilot of the PUSCH transmitted in the uplink time slot is located. Optionally, the PUSCH transmitted in the uplink time slot is rate matched in the OFDM where the demodulation pilot is located. The resource mapping is performed on the symbol. For example, FIG. 25A is the symbol of the demodulation pilot that uses the OFDM symbol closest to the GP as the demodulation pilot on the basis of FIG. 23B.

The third mode is related to the resource allocation mode of the PUSCH sent in the uplink pilot time slot, where the time-frequency resource used for transmitting the PUSCH in the uplink pilot time slot is adjacent to the special subframe after the special subframe in the radio frame When the uplink subframes are allocated to the terminal together, the terminal uses the pilot resource of the uplink subframe adjacent to the special subframe after the special subframe as the common PUSCH in the special subframe and the PUSCH in the uplink subframe. For the pilot resource, the base station does not reconfigure additional demodulation pilot resources for the PUSCH in the special subframe. For example, if the uplink-downlink configuration is 3, as shown in FIG. 25B, subframe 1 (special subframe) The symbol for transmitting the PUSCH in the UpPTS is allocated to the terminal together with the time-frequency resource of the subframe 2, and the PUSCH transmitted in the UpPTS of the subframe 1 and the PUSCH of the subframe 2 share the demodulation pilot resource of the subframe 2, and the subframe 1 The demodulation pilot resource is not additionally configured. When the time-frequency resource used for transmitting the PUSCH in the uplink pilot time slot is allocated to the terminal as an independent uplink resource, the terminal is configured according to the configuration of the base station (for example, The above method 1) or base station and terminal A predefined criterion (such as mode 2 above) determines demodulation pilot resources in the uplink pilot time slot.

The base station and the terminal allocated by the base station in the uplink pilot time slot in the third mode are pre-agreed by the base station and the terminal, or the base station is configured to the terminal by using signaling. Optionally, the base station may add the physical downlink control channel information. One bit is used to indicate whether the time-frequency resource used for transmitting the PUSCH in the uplink pilot time slot is allocated to the terminal separately or to the terminal together with the adjacent uplink subframe.

When the time-frequency resource used for transmitting the PUSCH in the uplink pilot time slot is allocated to the terminal together with the subsequent uplink subframe, if the number of symbols used for transmitting the PUSH in the uplink pilot time slot is M, then the M symbols The uplink PUSCH may be a repeated transmission of the PUSCH on the specified M symbols of the subsequent uplink subframe, where the OFDM symbol of the PUSCH used for the repeated transmission in the subsequent uplink subframe is pre-agreed by the base station and the terminal, or by The base station is configured to the terminal.

Alternative embodiment 4

In an optional embodiment, the timing relationship between the PUSCH and the PDCCH in the UpPTS is mainly.

The terminal sends a physical uplink shared channel to the base station on the time-frequency resource corresponding to the uplink pilot time slot in the special subframe of the radio frame, where the base station and the terminal determine the uplink pilot time slot in the special subframe according to a predefined criterion. Correspondence between the transmitted subframe index of the transmitted PUSCH and the PDSCH reception subframe index that schedules the PUSCH. Assuming that the terminal receives the PDCCH scheduling the PUSCH on the subframe n, the terminal will transmit the PUSCH on the subframe n+k. Another equivalent description is that if the terminal transmits the PUSCH on the subframe i, the terminal will be in the sub-frame. A PDCCH scheduling the PUSCH is received on the frame ik. When the uplink pilot time slot in the special subframe is used for resource allocation together with the uplink subframe adjacent to the special subframe after the special subframe, the special subframe in which the uplink pilot time slot of the PUSCH is transmitted is scheduled and the scheduling is performed. The correspondence between the PDCCH receiving subframe indexes of the PUSCH is transmitted according to the uplink subframe adjacent to the special subframe. The timing relationship between the PUSCH and the PDCCH receiving subframe in which the PUSCH is scheduled is performed, that is, if the TDD uplink-downlink configuration is 0/1/6, if the PUSCH is transmitted on the uplink pilot slot supporting the special subframe, The time-frequency resource in the uplink pilot time slot in the special subframe 1 is allocated to the terminal together with the uplink subframe 2, and the transmission subframe index of the PUSCH is the subframe 2, and the uplink pilot time slot in the special subframe 6. The time-frequency resource is allocated to the terminal together with the uplink subframe 7, and the transmission subframe index of the PUSCH is the subframe 7, wherein the timing between the PUSCH transmitted on the subframe 2 and the subframe 7 and the PDCCH scheduling the PUSCH The relationship is defined in the existing LTE protocol. Similarly, when the TDD uplink-downlink configuration is 2/3/4/5, the time-frequency resources and uplinks in the uplink pilot slots in the special subframe 1 are The subframe 2 is allocated to the terminal together, and the transmission subframe index of the PUSCH is the subframe 2, wherein the timing relationship between the PUSCH transmitted on the subframe 2 and the PDCCH scheduling the PUSCH is already defined in the existing LTE protocol.

When the uplink pilot time slot and the other uplink subframes in the special subframe are allocated to the terminal as separate uplink resources, the subframe index corresponding to the special subframe in which the uplink pilot time slot of the PUSCH is transmitted and the PDCCH receiving the PUSCH are scheduled. The correspondence between sub-frame indexes is shown in Figure 26:

When the TDD uplink-downlink configuration is 0, the transmission subframe index of the PUSCH transmitted in the uplink pilot slot in the special subframe 1 of the current radio frame is 1, and the PDCCH reception subframe index of the PUSCH is scheduled to be Subframe 5 in the previous radio frame, k=6, when the special subframe for transmitting the PUSCH has a subframe index of 6 in the current radio frame, the PDCCH receiving subframe index of the PUSCH is scheduled to be a sub-carrier in the current radio frame. Frame 0, k=6;

In the case that the TDD uplink-downlink configuration is 1, the transmission subframe index of the PUSCH transmitted in the uplink pilot time slot in the special subframe 1 of the current radio frame is 1, and the PDCCH reception subframe index of the PUSCH is scheduled to be The subframe 5 in the previous radio frame, k=6, the transmission subframe index of the PUSCH transmitted in the uplink pilot slot in the special subframe 6 of the current radio frame is 6, and the PDCCH receiving subframe of the PUSCH is scheduled. The index is subframe 0 in the current radio frame, k=6;

In the case that the TDD uplink-downlink configuration is 2, the transmission subframe index of the PUSCH transmitted in the uplink pilot slot in the special subframe 1 of the current radio frame is 1, and the PDCCH reception subframe index of the PUSCH is scheduled to be In the previous radio frame, the subframe 6 is k=5, and the transmit subframe index of the PUSCH transmitted in the uplink pilot slot in the special subframe 1 of the current radio frame is 1, and the PDCCH receiving subframe index of the PUSCH is scheduled. Is the subframe 1 in the current radio frame, k=5;

In the case that the TDD uplink-downlink configuration is 3, the transmission subframe index of the PUSCH transmitted in the uplink pilot slot in the special subframe 1 of the current radio frame is 1, and the PDCCH reception subframe index of the PUSCH is scheduled to be Subframe 7 in the previous radio frame, k=4;

In the case that the TDD uplink-downlink configuration is 4, the transmission subframe index of the PUSCH transmitted in the uplink pilot slot in the special subframe 1 of the current radio frame is 1, and the PDCCH reception subframe index of the PUSCH is scheduled to be Subframe 7 in the previous radio frame, k=4;

In the case that the TDD uplink-downlink configuration is 5, the transmit subframe index of the PUSCH transmitted in the uplink pilot slot in the special subframe 1 of the current radio frame is 1, and the PDCCH receive subframe index of the PUSCH is scheduled to be Previous Subframe 7 in the radio frame, k=4;

In the case that the TDD uplink-downlink configuration is 6, the transmission subframe index of the PUSCH transmitted in the uplink pilot slot in the special subframe 1 of the current radio frame is 1, and the PDCCH reception subframe index of the PUSCH is scheduled to be In the previous radio frame, subframe 5, k=6, when the special subframe for transmitting the PUSCH has a subframe index of 6 in the current radio frame, the PDCCH receiving subframe index of the PUSCH is scheduled to be the subframe in the current radio frame. 0, k = 6.

In the case that the TDD uplink-downlink configuration is 0, if the time-frequency resource corresponding to the uplink pilot time slot is independently allocated to the terminal, the ratio of the downlink subframe to the uplink subframe of one radio frame is 1:2. It is required that each downlink subframe needs to be able to schedule two uplink subframes.

In a case where the TDD uplink-downlink configuration is 0, when the PDCCH reception subframe in which the PUSCH is scheduled is the subframe 5 in the previous radio frame, the uplink PUSCH transmission subframe scheduled by the PDCCH may be the previous radio frame. The sub-frame 9 and/or the sub-frame 1 in the current radio frame are further distinguished by using an uplink index (UL index) field in the downlink control information carried in the PDCCH. In the related art, the UL index field has 2 bits. When the value of the most significant bit (MSB) in the UL index field is 1, the uplink PUSCH transmission subframe scheduled by the PDCCH is the subframe 9 in the previous radio frame, and the least effective in the UL index field. When the value of the bit (LSB) is 1, the uplink PUSCH transmission subframe scheduled by the PDCCH is the subframe 1 in the current radio frame (that is, the special subframe in which the uplink pilot slot is located); when the PDCCH receiver of the PUSCH is scheduled When the frame is the subframe 0 in the current radio frame, the uplink PUSCH transmission subframe scheduled by the PDCCH may be the subframe 4 and/or the subframe 6 in the current radio frame, and then the downlink control information carried in the PDCCH is utilized. The upper index (UL index) field for further differentiation, such as When the value of the most significant bit (MSB) in the UL index field is 1, the uplink subframe scheduled by the PDCCH is subframe 4 in the current radio frame, and the value of the least significant bit (LSB) in the UL index field is At 1 o'clock, the uplink transmission subframe scheduled by the PDCCH is the subframe 6 in the current radio frame (that is, the special subframe in which the uplink pilot slot is located).

In the case that the TDD uplink-downlink configuration is 6, if the time-frequency resources corresponding to the uplink pilot time slots are independently allocated to the terminal, the ratio of the downlink subframe to the uplink subframe of one radio frame is 5:7. It is indicated that there are two uplink subframes that need to be scheduled for two uplink subframes.

In a case where the TDD uplink-downlink configuration is 6, when the PDCCH reception subframe in which the PUSCH is scheduled is the subframe 5 in the previous radio frame, the uplink PUSCH transmission subframe scheduled by the PDCCH may be a sub-frame in the current radio frame. Frame 1 and/or subframe 2 are further distinguished by using an uplink index (UL index) field in the downlink control information carried in the PDCCH. In the related art, the UL index field has 2 bits, and the highest in the UL index field. When the value of the valid bit (MSB) is 1, the uplink PUSCH transmission subframe scheduled by the PDCCH is subframe 2 in the current radio frame, and when the value of the least significant bit (LSB) in the UL index field is 1, the The uplink PUSCH transmission subframe in which the PDCCH is scheduled is the subframe 1 in the current radio frame (that is, the special subframe in which the uplink scheduling slot is located); when the PDCCH reception subframe in which the PUSCH is scheduled is the subframe 0 in the current radio frame, The uplink PUSCH transmission subframe scheduled by the PDCCH may be the subframe 6 and/or the subframe 7 in the current radio frame, and then further differentiated by using an uplink index (UL index) field in the downlink control information carried in the PDCCH. For example, when the most significant bit (MSB) in the UL index field When the value of the value is 1, the uplink subframe scheduled by the PDCCH is the subframe 7 in the current radio frame, and the lowest value in the UL index field is When the value of the effect bit (LSB) is 1, the uplink transmission subframe scheduled by the PDCCH is the subframe 6 in the current radio frame (that is, the special subframe in which the uplink pilot slot is located).

As another embodiment of the present invention, considering that the TDD uplink-downlink configuration is 0, there are more uplink subframes except the special subframe, and the downlink subframe and the uplink subframe in each radio frame. The ratio is 2:3. Therefore, in this uplink-downlink configuration, the terminal and the base station can mutually agree not to support the terminal to use the uplink pilot time slot in the special subframe to transmit the PUSCH.

As another embodiment of the present invention, in consideration of the case where the TDD uplink-downlink configuration is 6, the uplink subframes other than the special subframes are also relatively large, and the downlink subframes and the uplink subframes in each radio frame are The ratio is 1:1. Therefore, in this uplink-downlink configuration, the terminal and the base station can also mutually agree not to support the terminal to use the uplink pilot time slot in the special subframe to transmit the PUSCH.

Correspondence between the transmitted subframe of the transmitted PUSCH and the PHICH received subframe index corresponding to the PUSCH. Assuming that the terminal transmits the PUSCH on the subframe n, the terminal will receive the PHICH corresponding to the PUSCH on the subframe n+k, or another equivalent statement is that, assuming that the terminal receives the PHICH on the subframe i, the terminal The PUSCH corresponding to the PHICH is transmitted on the subframe ik.

The correspondence between frame indexes is shown in Figure 27:

In the case that the TDD uplink-downlink configuration is 0, when the special subframe for transmitting the PUSCH has a subframe index of 1 in the current radio frame, the corresponding PHICH reception subframe index is the subframe 6 in the current radio frame, k =5, when the special subframe for transmitting the PUSCH has a subframe index of 6 in the current radio frame, the corresponding PHICH receiving subframe index is the subframe 1 in the next radio frame, k=5;
