Description

Uplink data transmission control method, transmission method and device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for controlling uplink data transmission.

Background

Full-Duplex (Full-Duplex) technology is a new technology that has attracted much attention in recent years, and when the Full-Duplex technology is applied, the Full-Duplex wireless communication system has more serious interference than a Frequency Division Duplex (FDD) or a Time Division Duplex (TDD) system, for example: the downlink data sent by the cell base station is interfered by the downlink data sent by the adjacent cell base station, and simultaneously is interfered by the uplink data sent by the user equipment of the cell and the adjacent cell, specifically:

fig. 1 shows an interference situation of downlink data of a conventional wireless communication system, as shown in fig. 1, a coverage area of a base station 102 is 104, a coverage area of a base station 106 is 108, and when a user equipment 110 receives the downlink data transmitted by the base station 102 of the cell, a main interference signal (a dotted Line in fig. 1 represents an interference signal) is from downlink data of other cell base stations (e.g., the base station 106), especially a base station in a neighboring cell or in a Line of Sight (LOS) path.

Fig. 2 shows an interference situation of downlink data of a full-duplex wireless communication system, as shown in fig. 2, a coverage area of a base station 202 is 204, a coverage area of a base station 206 is 208, and since the full-duplex wireless communication system allows uplink data of a user equipment and downlink data of the base station to be simultaneously transmitted, when the user equipment 210 receives the downlink data transmitted by the base station 202 of the cell, a main interference signal (a dotted line in fig. 2 indicates an interference signal) includes: 1. downlink data from base stations of other cells, for example: downlink data for base station 206; 2. uplink data of other user equipment in the cell, for example: uplink data transmitted by the user equipment 212; 3. uplink data of user equipment in a neighboring cell, for example: uplink data transmitted by the user equipment 214. The interference caused by the uplink data of the user equipment in the cell and the uplink data of the user equipment in the adjacent cell is not existed in the FDD system and the TDD system. Therefore, the signal interference of the full-duplex wireless communication system has a complexity and strength exceeding those of the FDD system and the TDD system.

From the perspective of the LTE downlink channel and the LTE uplink channel, the downlink control channel in the downlink channel has an important fundamental role in ensuring the normal communication capability of the system, and is distributed on the first n Orthogonal Frequency Division Multiplexing (OFDM) symbols of each downlink subframe. As shown in fig. 3, when n is 3, a Physical Control Format Indicator Channel (PCFICH) 302 in the downlink Control Channel is located on the first OFDM symbol of the downlink subframe; a Physical HARQ Indicator Channel (PHICH) 304 may be located on the first 1-3 OFDM symbols of the downlink subframe according to configuration; a Physical Downlink Control Channel (PDCCH) 306 may be located on the first 1-4 OFDM symbols of the Downlink subframe according to configuration and system parameters, and if the PDCCH is subjected to strong interference, system performance may be rapidly reduced.

In the LTE Uplink Channel, as shown in fig. 4A, a Physical Uplink Control Channel (PUCCH) 402 is used to carry control information fed back by the ue, generally occupies resources on both sides of the system bandwidth, other resources are used for a Physical Uplink Shared Channel (PUSCH) 404, and the PUCCH 402 and PUSCH 404 are transmitted on a full subframe of an Uplink subframe; specifically, when an uplink subframe in the uplink channel is configured as a Sounding Reference Signal (SRS) subframe, as shown in fig. 4B, the last OFDM symbol in the uplink subframe is vacated for transmitting an SRS 406, and the PUCCH 402 and PUSCH 404 are transmitted in other OFDM symbols except for the last OFDM symbol in the uplink subframe.

From the perspective of the LTE downlink channel and the LTE uplink channel, when data transmitted by the uplink channel and the downlink channel are simultaneously and co-frequency transmitted, that is, when data transmitted by the uplink channel and the downlink channel are transmitted in the same subframe, the user equipment will simultaneously receive a subframe in which the base station transmits downlink data and a subframe in which other user equipment transmits uplink data, and an uplink physical channel in the subframe transmitting uplink data will generate severe interference with a downlink control channel in the subframe transmitting downlink data, resulting in rapid degradation of system performance.

To sum up, the interference situation of the full duplex wireless communication system is more complex than that of the existing FDD system or TDD system, the uplink data of the user equipment and the downlink data of the base station are transmitted at the same time and at the same frequency, the user equipment receives the subframe in which the downlink data is transmitted by the base station and the subframe in which the uplink data is transmitted by other user equipment at the same time, and the uplink physical channel in the subframe for transmitting the uplink data generates severe interference on the downlink control channel in the subframe for transmitting the downlink data, resulting in rapid degradation of the system performance.

Detailed Description

The following describes in detail a specific implementation of an uplink data transmission control method, a transmission method, and an apparatus according to an embodiment of the present invention with reference to the accompanying drawings.

It should be noted that, in the embodiment of the present invention, based on a full-duplex wireless communication system, in the full-duplex wireless communication system, uplink data of a user equipment and downlink data sent by a base station are transmitted in the same subframe, uplink and downlink data transmission in the same time domain and frequency domain is supported, and there is no distinction between an uplink subframe and a downlink subframe. Therefore, for ease of description, logically we describe using the following concepts: the full-duplex subframe simultaneously supports uplink and downlink data transmission by using domain and frequency domain resources; the "full duplex downlink subframe" is a downlink part in the "full duplex subframe"; the "full duplex uplink subframe" is the uplink portion of the "full duplex subframe". The configuration information of the full-duplex uplink subframe is configured for the user equipment by the network side, and is used for instructing the user equipment to transmit uplink data according to the configuration information of the full-duplex uplink subframe. Of course, in the full duplex wireless communication system, the ue can simultaneously receive the full duplex downlink subframe in which the network side transmits downlink data and the full duplex uplink subframe in which other ues transmit uplink data to the network side.

On the network side, taking a base station as an example, an uplink data transmission control method provided in an embodiment of the present invention is, as shown in fig. 5, the method including:

step 502, a base station determines configuration information of a full-duplex uplink subframe of user equipment, wherein the configuration information comprises information supporting time division multiplexing of an uplink physical channel and a downlink physical channel of a same-frequency carrier in the same full-duplex subframe;

step 504, the base station sends the configuration information of the full-duplex uplink subframe to the user equipment, so as to instruct the user equipment to transmit uplink data according to the configuration information of the full-duplex uplink subframe, wherein an uplink physical channel in the full-duplex uplink subframe for the user equipment to transmit the uplink data is time division multiplexed with a downlink physical channel of a common-frequency carrier.

In the method provided by the embodiment of the invention, the configuration information of the full-duplex uplink subframe comprises information supporting time division multiplexing of an uplink physical channel and a downlink physical channel of a same-frequency carrier in the same full-duplex subframe, so that the uplink physical channel in the full-duplex uplink subframe for transmitting uplink data by the user equipment and the downlink physical channel in the full-duplex downlink subframe for transmitting downlink data (for example, downlink data transmitted by a base station) of the same-frequency carrier are time division multiplexed, and when the user equipment simultaneously receives the full-duplex uplink subframe for transmitting uplink data by other user equipment and the full-duplex downlink subframe for transmitting downlink data by the same-frequency carrier, the interference of the uplink physical channel in the full-duplex uplink subframe on the downlink physical channel in the full-duplex downlink subframe, especially the interference of the uplink physical channel in the full-duplex uplink subframe on the downlink control channel in the full-duplex subframe is reduced, compared with the prior art that the uplink physical channel in the subframe for transmitting the uplink data generates serious interference on the downlink control channel in the subframe for transmitting the downlink data, the interference of the uplink physical channel in the full-duplex uplink subframe on the downlink control channel in the full-duplex downlink subframe is reduced, and therefore the system performance is improved.

In a possible implementation manner, in the method provided in the embodiment of the present invention, the downlink physical channel includes a downlink control channel.

Of course, the downlink physical channel may also include: physical Broadcast Channel (PBCH), Physical Downlink Shared Channel (PDSCH), Physical Multicast Channel (PMCH), Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and pilot Signal (ReferenceSignals). In the embodiment of the present invention, a downlink control channel is taken as an example for description.

In a possible implementation manner, in the method provided in the embodiment of the present invention, an uplink physical channel time-division multiplexed with a downlink physical channel of a co-frequency carrier in the same full-duplex subframe is a physical uplink shared channel, or at least includes a physical uplink shared channel and a physical uplink control channel.

Of course, the uplink physical channel may also include: physical Random Access Channel (PRACH).

In specific implementation, the time division multiplexing of the uplink physical channel in the same full-duplex subframe and the downlink physical channel of the same-frequency carrier is divided into the following two implementation modes:

the first implementation mode comprises the following steps: the physical uplink channel time division multiplexed with the physical downlink channel of the same frequency carrier in the same full duplex subframe is a physical uplink shared channel, and the physical uplink control channel reserves the original format so as to reduce the change of the existing standard.

In a possible implementation manner, in the method provided in this embodiment of the present invention, when an uplink physical channel time-division multiplexed with a downlink physical channel of a common-frequency carrier in the same full-duplex subframe is a physical uplink shared channel, determining configuration information of a full-duplex uplink subframe of a user equipment specifically includes: determining first configuration information that initial N Orthogonal Frequency Division Multiplexing (OFDM) symbols in a physical uplink shared channel in a full-duplex uplink subframe for transmitting uplink data by user equipment do not bear transmission data, wherein N is a natural number; sending configuration information of a full-duplex uplink subframe to user equipment, specifically: and sending the first configuration information to the user equipment.

In a preferred embodiment, N is a natural number in the range of [1, 4 ].

It should be noted that the downlink control channel in the full-duplex downlink subframe is located on the first N OFDM symbols of the full-duplex downlink subframe, and the PCFICH is located on the first OFDM symbol, so that the base station configures the first N OFDM symbols in the physical uplink shared channel not to carry transmission data, and N may be set according to an actual situation or adopt a system default value. For example: when N is 1, the first OFDM symbol of the full-duplex uplink subframe does not carry transmission data, the first OFDM symbol in the downlink control channel of the full-duplex downlink subframe is not interfered by the full-duplex uplink subframe, if the downlink control channel in the full-duplex downlink subframe only has 1 OFDM symbol, the downlink control channel in the full-duplex downlink subframe is not interfered by the full-duplex uplink subframe at all, if the downlink control region is a plurality of symbols, the PCFICH is not interfered by the full-duplex uplink subframe at all, and the PDCCH and the PHICH are partially interfered by the full-duplex uplink subframe.

As a more preferable embodiment, the value of N is the same as the number of OFDM symbols occupied by the downlink control channel, and the downlink control channel in the full-duplex downlink subframe is not affected by the full-duplex uplink subframe at all, thereby improving the system performance.

As a more specific embodiment, when the user equipment receives the first configuration information sent by the base station and transmits uplink data according to the first configuration information, the user equipment controls the initial N OFDM symbols in the physical uplink shared channel of the full-duplex uplink subframe not to carry transmission data. As shown in fig. 6, for example: when N is 3, the first 3 OFDM symbols in the physical uplink shared channel of the full-duplex uplink subframe in which the ue transmits uplink data do not carry transmission data, and therefore, any ue receives the full-duplex uplink subframe 606 and the full-duplex uplink subframe 608 in which other ues transmit uplink data, and the full-duplex downlink subframe 602 and the full-duplex downlink subframe 604 in which the base station transmits downlink data at the same time, where downlink control channels of the full-duplex downlink subframe are distributed on the first 3 OFDM symbols of the full-duplex downlink subframe 602 and the full-duplex downlink subframe 604, and the first 3 OFDM symbols (the region 610 in fig. 6) in the physical uplink shared channels of the full-duplex uplink subframe 606 and the full-duplex uplink subframe 608 do not carry transmission data, so that interference of the full-duplex uplink subframe on the downlink control channel of the full-duplex downlink subframe can be reduced.

The base station performs data scheduling by adjusting the size of a scheduling packet, a modulation and coding scheme, and the like according to information such as a transmission quality requirement and the like and factors such as reduction of available resources caused by avoiding interference of a downlink control channel; the user equipment performs uplink data transmission according to the scheduling instruction, and the mapping mode may adopt an existing LTE mode, which is not described herein again.

The second embodiment: the uplink physical channel time division multiplexed with the downlink physical channel of the same-frequency carrier in the same full-duplex subframe at least comprises a physical uplink shared channel and a physical uplink control channel, so that the influence of the uplink subframe on the downlink control channel in the downlink subframe is reduced to the maximum extent, and the system performance is improved.

In a possible implementation manner, in the method provided in this embodiment of the present invention, when an uplink physical channel time-division multiplexed with a downlink physical channel of a common-frequency carrier in the same full-duplex subframe at least includes a physical uplink shared channel and a physical uplink control channel, determining configuration information of a full-duplex uplink subframe of a user equipment specifically includes: determining that the initial N OFDM symbols in a physical uplink shared channel in a full-duplex uplink subframe for transmitting uplink data by user equipment do not bear transmission data, and determining second configuration information that the initial N OFDM symbols in a physical uplink control channel in the full-duplex uplink subframe for transmitting uplink data by the user equipment do not bear transmission data; sending configuration information of a full-duplex uplink subframe to user equipment, specifically: and sending the second configuration information to the user equipment.

In a possible implementation manner, in the method provided by the embodiment of the present invention, when N is 1, determining that first 1 OFDM symbols in a physical uplink shared channel in a full-duplex uplink subframe in which the user equipment transmits uplink data do not carry transmission data, and first 1 OFDM symbols in a physical uplink control channel in a full-duplex uplink subframe in which the user equipment transmits uplink data do not carry second configuration information of transmission data, specifically includes: configuring a full-duplex uplink subframe for transmitting uplink data by user equipment as a channel Sounding Reference Signal (SRS) subframe, and configuring OFDM symbols for transmitting SRS signals in the SRS subframe not to bear SRS signal transmission; taking the configuration information of the SRS subframe as second configuration information; or delaying the configuration information of the SRS subframe by the time length of one OFDM symbol in the time domain to obtain the configuration information of the SRS subframe.

In particular implementation, since the last OFDM symbol in the SRS subframe in the prior art carries SRS signal transmission, therefore, when N is 1, the base station determines that the first 1 OFDM symbols in the physical uplink shared channel in the full-duplex uplink subframe for the user equipment to transmit the uplink data do not carry the transmission data, and the first 1 OFDM symbol in the physical uplink control channel in the full-duplex uplink subframe where the user equipment transmits uplink data does not carry transmission data, a full-duplex uplink subframe where the user equipment transmits uplink data may be configured as an SRS subframe, and configures the OFDM symbol for transmitting SRS signal in the SRS subframe not to carry SRS signal transmission, that is, the last OFDM symbol in the SRS subframe is "blank" (not carrying transmission data), and simultaneously delaying the time length of one OFDM symbol of the full-duplex uplink subframe in the time domain so as to lead the full-duplex uplink subframe to be time division multiplexed with the first OFDM symbol of the downlink control channel of the full-duplex downlink subframe.

As a more specific example, as shown in fig. 7, the full-duplex uplink subframe 706 and the full-duplex uplink subframe 708 are SRS subframes and the last OFDM symbol is "blank" (does not carry transmission data), when the full-duplex uplink subframe is delayed by one OFDM symbol (region 710 in fig. 7) in the time domain, the user equipment simultaneously receives the full-duplex uplink subframe 706 and the full-duplex uplink subframe 708 where other user equipment sends uplink data, and the full-duplex downlink subframe 702 and the full-duplex downlink subframe 704 where the base station sends downlink data, the full-duplex uplink subframe 706 has no influence on the first OFDM symbol of the downlink control channel of the full-duplex downlink subframe 702, the full-duplex uplink subframe 708 has no influence on the first OFDM symbol of the downlink control channel of the full-duplex downlink subframe 704, that is, the ficpch in the downlink control channel of the full-duplex downlink subframe is not influenced by the full-duplex uplink subframe, the system performance is improved.

Of course, it should be noted that the time length of the SRS subframe delayed by one OFDM symbol in the time domain may be obtained by using the configuration information of the SRS subframe and the configuration information of the SRS subframe delayed by one OFDM symbol in the time domain as the second configuration information. The configuration information of the SRS subframe delayed by the time length of one OFDM symbol in the time domain specifically includes: a new timing advance TA ', where the new timing advance TA' is a time length of the timing advance TA that is delayed by one OFDM symbol.

The method includes the steps of delaying the time length of an OFDM symbol of an SRS subframe in a time domain, sending configuration information of the SRS subframe to user equipment as second configuration information through a base station, and when the user equipment determines that the second configuration information is the configuration information of the SRS subframe and uses a full-duplex transmission mode, transmitting uplink data according to the configuration information of the SRS subframe after the time length of the OFDM symbol is delayed from a time starting point of transmitting the uplink data.

Certainly, the determining, by the base station, that the first N OFDM symbols in the physical uplink shared channel in the full-duplex uplink subframe of the user equipment do not carry transmission data and the first N OFDM symbols in the physical uplink control channel in the full-duplex uplink subframe of the user equipment do not carry transmission data may further include: the base station adjusts the size of a scheduling data packet, a modulation coding mode and the like according to information such as transmission quality requirements and the like and factors such as reduction of available resources caused by avoiding interference of a downlink control channel, and performs data scheduling; the user equipment transmits uplink data according to the scheduling instruction, and the mapping mode can adopt the existing LTE mode.

As a more specific embodiment, when the user equipment receives the second configuration information sent by the base station, and when the user equipment transmits uplink data according to the second configuration information, the user equipment controls that none of the initial N OFDM symbols in the physical uplink shared channel and the physical uplink control channel of the full-duplex uplink subframe for transmitting the uplink data carries transmission data. As shown in fig. 8, for example: n is 3, the first 3 OFDM symbols in the physical uplink shared channel and the physical uplink control channel of the full-duplex uplink subframe in which the ue transmits uplink data do not carry transmission data, so that any ue receives the full-duplex uplink subframe 806 and the full-duplex uplink subframe 808 in which other ues transmit uplink data, and the full-duplex downlink subframe 802 and the full-duplex downlink subframe 804 in which the base station transmits downlink data, at the same time, wherein the downlink control channels of the full-duplex downlink subframe are distributed over the first 3 OFDM symbols of the full-duplex downlink subframe 802 and the full-duplex downlink subframe 804, and the first 3 OFDM symbols (region 810 in fig. 8) in the physical uplink shared channel and the physical uplink control channel of the full-duplex uplink subframe 806 and the full-duplex uplink subframe 808 do not carry transmission data, thereby reducing the interference of the full-duplex uplink subframe on the downlink control channel of the full-duplex downlink subframe, and the system performance is improved.
