Description

Uplink data transmission method and device

Technical Field

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

Background

In an LTE (long term evolution) system, limited by the maximum transmission power of a UE (user equipment), the available transmission power of each data packet in a TTI (transmission time interval) is limited, and therefore, under a severe channel condition, uplink transmission cannot meet performance requirements. In order to improve the uplink coverage effect, the LTE system adopts an enhanced technology and introduces an uplink TTIbundling (binding) scheme. The so-called TTIbundling scheme is that the UE transmits different RVs (redundancy versions) of the same TB (transport block) after channel coding in multiple subframes based on one scheduling instruction of the base station, so that the transmission gain of uplink data can be improved, thereby enhancing the coverage effect of uplink signals. The plurality of uplink subframes are referred to as a bundle (bundle) of bundled subframes.

Currently, in an LTE system, a bundle size is defined to be 4, that is, one bundle includes four uplink subframes.

For an FDD (frequency division duplex) system, after adopting a TTIbundling scheme, the UE sends different RVs of the same TB in four consecutive uplink subframes, and the base station combines the received RVs and then decodes the combined RVs. For example, as shown in fig. 1, when TTIbundling (i.e., non-bundling) is not configured, the duration of an uplink RTT (round trip time) is 8ms, and the number of HARQ (hybrid automatic repeat request) processes within one RTT is 8; after the TTIbundling is configured, the duration of the uplink RTT is twice of the original uplink RTT, that is, 16ms, and the number of HARQ processes within one RTT is reduced by half, that is, the number is 4. The RTT may be defined as a time interval from initial transmission to retransmission of the same process, and for a case of using TTIbundling, a first subframe in the same process is used as a reference. Each HARQ process transmits a different data block. The total number of HARQ processes is the maximum possible number of data blocks that have been transmitted at any one point in time but have not received feedback on the transmission result (i.e. correct or incorrect reception of the data block).

For TDD (time division duplex) systems, the number of consecutive uplink subframes is smaller than the specified size of bundle, and therefore different RVs of the TB are transmitted in the discontinuous uplink subframes. In the prior art, TTIbundling operations are designed only for uplink and downlink configurations 0, 1 and 6, which will be described below.

As shown in fig. 2, for uplink and downlink configuration 0, in a non-bundling, the number of uplink HARQ processes is 7 in one RRT, and after TTIbundling is configured, the number of uplink HARQ processes is 3 in one RRT, and one bundle includes 4 uplink subframes.

As shown in fig. 3, for uplink and downlink configuration 1, when in non-bundling, the number of uplink HARQ processes is 4 in one RRT; after the TTIbundling is configured, in one RRT, the number of uplink HARQ processes is 2, and one bundle includes 4 uplink subframes.

As shown in fig. 4, for uplink and downlink configuration 6, in non-bundling, the number of uplink HARQ processes is 6 in one RRT, and after TTIbundling is configured, the number of uplink HARQ processes is 3 in one RRT, and one bundle includes 4 uplink subframes.

In the existing LTE system, the bundling size is small, and even some TDD uplink and downlink configurations (such as uplink and downlink configurations 2, 3, 4, and 5) do not support TTIbundling, which limits uplink coverage.

Detailed Description

In order to improve the transmission gain of uplink data, in the embodiment of the present invention, a corresponding TIIbundling scheme is designed, that is, according to the number of uplink subframes in each radio frame (radio frame), a UE sends different RVs of the same TB after channel coding on at least two uplink subframes in a bundle, so as to implement multiple transmission of the same uplink data.

Referring to fig. 5, the uplink data transmission method provided in the embodiment of the present invention includes the following steps:

step 50: the terminal respectively sends different redundancy versions of the first TB on K subframes in the Nth bundling-HARQRTT;

step 51: the terminal receives an uplink control signaling sent by a network side on a subframe N in the nth bundling-HARQRTT and carries out subsequent processing, wherein the uplink control signaling is used for indicating the transmission result of the first TB and the data transmission mode on K subframes in the (N +1) th bundling-HARQRTT;

wherein N is an integer not less than 0; k is an integer larger than 1, and K subframes in the Nth bundling-HARQRTT correspond to the same HARQ process number with K subframes in the (N +1) th bundling-HARQRTT; the bundling-HARQRTT is the HARQRTT when the TTIbundling scheme is adopted, and the bundling-HARQRTT can be twice the HARQRTT when the TTIbundling scheme is not adopted. The data transmission mode on the K subframes in the (N +1) th bundling-HARQRTT comprises the condition that data are not transmitted on the K subframes in the (N +1) th bundling-HARQRTT.

Specifically, the timing relationship between the subframe N in step 51 and the last subframe in the K subframes in the nth bundling-HARQ rtt complies with the uplink HARQ timing relationship specified in the LTE system protocol, that is, 3GPP36.213, that is, when the subframe N is non-bundling, the UE specified in the LTE system protocol receives the subframe in which the PHICH information corresponding to the uplink data packet in the last subframe in the K subframes in the nth bundling-HARQ rtt is located.

The uplink control signaling received by the terminal in step 51 at least includes an acknowledgement/negative acknowledgement (ACK/NACK) indication.

Further, the uplink control signaling may include uplink scheduling grant (ULgrant) signaling.

Specifically, the terminal receives the uplink control signaling sent by the network side on the subframe N within the nth bundling-harq rtt, and performs subsequent processing, which may be specifically implemented as follows:

if the uplink control signaling indicates to retransmit the first TB and does not indicate to send the second TB, for example, NACK is received and ULgrant signaling is not received, different redundancy versions of the first TB are respectively sent on K subframes in the (N +1) th bundling-HARQ RTT;

if the uplink control signaling indicates that the first TB does not need to be retransmitted and does not indicate to send the second TB, for example, if an ACK is received and a ULgrant signaling is not received, the data block is not sent;

if the uplink control signaling indicates to send the second TB, for example, the ACK and ul grant signaling are received, different redundancy versions of the second TB are sent on K subframes within the (N +1) th bundling-harq rtt, respectively.

Preferably, when a TDD uplink and downlink subframe configuration 0, a TDD uplink and downlink subframe configuration 1, a TDD uplink and downlink subframe configuration 6, or an FDD mode is adopted, K is an integer greater than 4;

when TDD uplink and downlink subframe configuration 2, TDD uplink and downlink subframe configuration 3, TDD uplink and downlink subframe configuration 4 or TDD uplink and downlink subframe configuration 5 is adopted, K is an integer larger than 1.

For example, the following steps are carried out:

example 1, when a TDD uplink/downlink subframe configuration 0 is adopted, the value of K is 7 or 8;

example 2, when TDD uplink and downlink subframe configuration 1 is adopted, the value of K is 5;

example 3, when TDD uplink and downlink subframe configuration 2 is adopted, the value of K is 3 or 2;

example 4, when TDD uplink and downlink subframe configuration 3 is adopted, the value of K is 6;

example 5, when TDD uplink and downlink subframe configuration 4 is adopted, the value of K is 4;

example 6, when TDD uplink and downlink subframe configuration 5 is adopted, the value of K is 2;

example 7, when TDD uplink and downlink subframe configuration 6 is adopted, K takes a value of 8 or 6;

example 8 in FDD mode, K takes the value 8.

In the method, the number of processes of bundling-HARQ can be floor (M/K), wherein M is the number of uplink subframes contained in bundling-HARQ RTT; floor denotes rounding down.

Specifically, when the number of bundling-HARQ processes is 1, K subframes within the nth bundling-HARQ rtt are specific or arbitrary consecutive K subframes in the uplink subframe set within the nth bundling-HARQ rtt. The row subframe set comprises all uplink subframes in the nth bundling-HARQ RTT;

when the number of bundling-HARQ processes is greater than 1, setting K subframes in an Nth bundling-HARQ process as subframes corresponding to an mth bundling-HARQ process, wherein the subframes corresponding to the mth bundling-HARQ process are K subframes from (m-1) K +1 subframes to mth K subframes in an uplink subframe set in the Nth bundling-HARQ process, namely, each subframe in { (m-1) K +1, (m-1) K + 2., m.K }; m is any positive integer less than floor (M/K) + 1. The bundling-HARQ process number may start with 0 or 1, but both are denoted as the first bundling-HARQ process.

Referring to fig. 6, an embodiment of the present invention provides an uplink data transmission method, including the following steps:

step 60: the network side respectively receives different redundancy versions of a first TB sent by a terminal on K subframes in an Nth bundling-HARQRTT;

step 61: the network side sends an uplink control signaling to the terminal on a subframe N in the nth bundling-HARQRTT according to the transmission result of the first TB, wherein the uplink control signaling is used for indicating the transmission result of the first TB and the data transmission mode on K subframes in the (N +1) th bundling-HARQRTT;

Specifically, the timing relationship between the subframe N in step 61 and the last subframe in the K subframes in the nth bundling-HARQ rtt complies with the uplink HARQ timing relationship specified in the LTE system protocol, that is, when the subframe N is a non-bundling subframe, the UE specified in the LTE system protocol receives the subframe where the PHICH information corresponding to the uplink data packet in the last subframe in the K subframes in the nth bundling-HARQ rtt is located.

The uplink control signaling sent by the network side in step 61 at least includes ACK/NACK indication.

Further, the uplink control signaling may include ul grant signaling.

Specifically, the network side sends the uplink control signaling to the terminal on the subframe N within the nth bundling-harq rtt according to the transmission result of the first TB, and the specific implementation may be as follows:

if the first TB fails to be transmitted and the terminal is not required to send the second TB, indicating the terminal to respectively send different redundancy versions of the first TB on K subframes in the (N +1) bundling-HARQ RTT through an uplink control signaling (such as NACK);

if the first TB is successfully transmitted and the terminal is not required to send the second TB, indicating that the first TB is successfully transmitted through an uplink control signaling (such as ACK);

if the first TB is successfully transmitted and the terminal is required to send the second TB, the terminal is instructed by uplink control signaling (for example, ACK and ul grant signaling) to send different redundancy versions of the second TB on K subframes within the (N +1) th bundling-harq rtt.

For example, the following steps are carried out:

example 8 in FDD mode, K takes the value 8.

Specifically, when the number of bundling-HARQ processes is 1, K subframes within the nth bundling-HARQ rtt are specific or arbitrary consecutive K subframes in the uplink subframe set within the nth bundling-HARQ rtt.

The invention is illustrated below with reference to specific examples:

the first embodiment is as follows:

in this embodiment, TDD uplink and downlink configuration is adopted, where bundling size, i.e., K, is 8, and only 1 bundling-HARQ process is supported, where the bundling-HARQ process corresponds to 8 consecutive uplink subframes in an uplink subframe set within one bundling-HARQ rtt. For example, the K subframes in bundling-harqrrtt are respectively:

uplink subframe 2, uplink subframe 3, uplink subframe 4, uplink subframe 7, uplink subframe 8, and uplink subframe 9 of radio frame P, and uplink subframe 2 and uplink subframe 3 of radio frame P +1, as shown in fig. 7; or,

an uplink subframe 3, an uplink subframe 4, an uplink subframe 7, an uplink subframe 8 and an uplink subframe 9 of a radio frame P, and an uplink subframe 2, an uplink subframe 3 and an uplink subframe 4 of a radio frame P + 1; or,

an uplink subframe 4, an uplink subframe 7, an uplink subframe 8 and an uplink subframe 9 of a radio frame P, and an uplink subframe 2, an uplink subframe 3, an uplink subframe 4 and an uplink subframe 7 of a radio frame P + 1; or,

an uplink subframe 7, an uplink subframe 8 and an uplink subframe 9 of a radio frame P, and an uplink subframe 2, an uplink subframe 3, an uplink subframe 4, an uplink subframe 7 and an uplink subframe 8 of a radio frame P + 1; or,

an uplink subframe 9 of a radio frame P, an uplink subframe 2, an uplink subframe 3, an uplink subframe 4, an uplink subframe 7, an uplink subframe 8 and an uplink subframe 9 of a radio frame P +1, and an uplink subframe 2 of the radio frame P + 2; or,

uplink subframe 2, uplink subframe 3, uplink subframe 4, uplink subframe 7, uplink subframe 8, and uplink subframe 9 of radio frame P +1, and uplink subframe 2 and uplink subframe 3 of radio frame P + 2.

The flow at the UE side is as follows:

step 1, UE respectively sends different redundancy versions of the uplink data packet on K subframes in the Nth bundling-HARQRTT, and when the redundancy version L defined by the system is less than K, the repeated use is not excluded. For example, RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3- > RV1, which can transmit uplink packets respectively, but is not limited to the above combinations;

step 2, the UE detects ACK/NACK indication sent by a base station through a physical hybrid automatic repeat request indication channel (PHICH) in a downlink subframe n; or,

the UE detects an ACK/NACK instruction sent by a base station through a PHICH and an ULgrant signaling sent through a downlink control information format 0(DCIformat0) on a Physical Downlink Control Channel (PDCCH) in a downlink subframe n;

the timing relationship between the subframe N and the last subframe of the K subframes within the nth bundling-HARQ rtt complies with the uplink HARQ timing relationship specified in the LTE system protocol, for example, in the first case shown in fig. 5, the downlink subframe N is 10 (P + 2); namely, the subframe of G in fig. 7;

and step 3, the UE retransmits the RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3- > RV1 of the uplink data packet on K subframes in the N +1 bundling-HARQRTT or transmits the RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3- > RV1 of a new uplink data packet according to the detected ACK/NACK indication or the ACK/NACK indication and the ULgrant signaling or does not transmit data.

A base station side:

step 1, the base station respectively receives RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3- > RV1 of an uplink data packet sent by the terminal on K subframes in the Nth bundling-HARQRTT, combines the subframes and judges whether uplink transmission is successful or not;

step 2, the base station sends ACK/NACK indication to the UE through PHICH in a downlink subframe n according to an uplink transmission result; or,

the base station sends ACK/NACK indication to the UE through PHICH in a downlink subframe n according to an uplink transmission result, and sends ULgrant signaling through DCIformat0 on PDCCH;

and step 3, the base station receives RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3- > RV1 of the uplink data packet retransmitted by the UE or RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3- > RV1 of the new transmitted uplink data packet on K subframes in the N +1 bundling-HARQRTT.

In this embodiment, the number of bundling-HARQ processes is 1; the bundling-harqrrtt is twice the harqrrtt without the TTIbundling scheme, and is 20 ms.

Example two:

in this embodiment, TDD uplink and downlink configuration 0 is adopted, where bundling size, that is, K, is 7, and 2 bundling-HARQ processes are supported, where a first bundling-HARQ process corresponds to first to seventh uplink subframes in a bundling-HARQ uplink subframe set, and a second bundling-HARQ process corresponds to eighth to fourteenth uplink subframes in the bundling-HARQ uplink subframe set. For example, the K uplink subframes corresponding to one bundling-HARQ process are respectively: uplink subframe 2, uplink subframe 3, uplink subframe 4, uplink subframe 7, uplink subframe 8 and uplink subframe 9 of radio frame P, and uplink subframe 2 of radio frame P + 1; the K uplink subframes corresponding to the other bundling-HARQ process are respectively: uplink subframe 3, uplink subframe 4, uplink subframe 7, uplink subframe 8, and uplink subframe 9 of radio frame P +1, and uplink subframe 2 and uplink subframe 3 of radio frame P +2, as shown in fig. 8.

The flow at the UE side is as follows:

step 1, the UE sends different redundancy versions of the uplink data packet on K subframes within the nth bundling-harq rtt, for example, RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3 which can send the uplink data packet respectively, and assuming that RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3 is sent according to the subframe sequence without loss of generality; the 3gpp ts36.321 defines the RV version transmission sequence to be 0, 2, 3, 1, and the RV version transmission sequence 0, 1, 2, 3 or 0, 2, 3, 1 in the present invention is only an embodiment, and does not limit another RV version transmission sequence;

the timing relationship between the subframe N and the last subframe in the K subframes within the nth bundling-HARQ rtt complies with the uplink HARQ timing relationship specified in the LTE system protocol, and for process 1, the downlink subframe N is 10 (P +2), that is, the subframe where G1 in fig. 8 is located; for process 2, downlink subframe n is 10 × (P +3), i.e. the subframe where G2 in fig. 8 is located;

and step 3, the UE retransmits the RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3 of the uplink data packet on K subframes in the N +1 bundling-HARQRTT or transmits the RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3 of a new uplink data packet according to the detected ACK/NACK indication or the ACK/NACK indication and the ULgrant signaling, or does not transmit data.

A base station side:

step 1, the base station respectively receives RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3 of an uplink data packet sent by the terminal on K subframes in the Nth bundling-HARQRTT, combines the subframes and judges whether uplink transmission is successful or not;

and step 3, the base station receives RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3 of the uplink data packet retransmitted by the UE or RV0- > RV2- > RV3- > RV1- > RV0- > RV2- > RV3 of the new uplink data packet transmitted on K subframes in the N +1 bundling-HARQRTT.

In this embodiment, the number of bundling-HARQ processes is 2; the bundling-harqrrtt is twice the harqrrtt without the TTIbundling scheme, and is 20 ms.

Example three:

in this embodiment, TDD uplink and downlink configuration 1 is adopted, where bundling size, i.e., K, is 5, and only 1 bundling-HARQ process is supported, where the bundling-HARQ process corresponds to 5 consecutive uplink subframes in a bundling-HARQ rtt uplink subframe set. For example, the K subframes in bundling-harqrrtt are respectively:

uplink subframe 2, uplink subframe 3, uplink subframe 7, and uplink subframe 8 of radio frame P, and uplink subframe 2 of radio frame P +1, as shown in fig. 9; or,

an uplink subframe 3, an uplink subframe 7 and an uplink subframe 8 of a radio frame P, and an uplink subframe 2 and an uplink subframe 3 of a radio frame P + 1; or,

an uplink subframe 7 and an uplink subframe 8 of a radio frame P, and an uplink subframe 2, an uplink subframe 3 and an uplink subframe 7 of a radio frame P + 1; or,

an uplink subframe 8 of a radio frame P, and an uplink subframe 2, an uplink subframe 3, an uplink subframe 7, and an uplink subframe 8 of a radio frame P + 1.

The flow at the UE side is as follows:

step 1, the UE respectively sends different redundancy versions of the uplink data packet on K subframes in the Nth bundling-HARQRTT, such as RV0- > RV2- > RV3- > RV1- > RV 0;

the timing relationship between the subframe N and the last subframe of the K subframes within the nth bundling-HARQ rtt complies with the uplink HARQ timing relationship specified in the LTE system protocol, for example, in the first case shown in fig. 9, the downlink subframe N is 10 (P +1) +6, that is, the subframe where G is located in fig. 9;

and step 3, the UE retransmits RV0- > RV2- > RV3- > RV1- > RV0 of the uplink data packet or transmits RV0- > RV2- > RV3- > RV1- > RV0 of a new uplink data packet or does not transmit data on K subframes in the N +1 bundling-HARQRTT according to the detected ACK/NACK indication or the ACK/NACK indication and the ULgrant signaling.

A base station side:

step 1, respectively receiving RV0- > RV2- > RV3- > RV1- > RV0 of an uplink data packet sent by a terminal on K subframes in an Nth bundling-HARQRTT, merging the subframes, and judging whether uplink transmission is successful or not;

and step 3, the base station receives RV0- > RV2- > RV3- > RV1- > RV0 of the uplink data packet retransmitted by the UE or RV0- > RV2- > RV3- > RV1- > RV0 of the new uplink data packet on K subframes in the (N +1) bundling-HARQRTT.

Example four:

in this embodiment, TDD uplink and downlink configuration 2 is adopted, where bundling size, i.e., K, is 3, and only 1 bundling-HARQ process is supported, where the bundling-HARQ process corresponds to 3 consecutive uplink subframes in a bundling-HARQ rtt uplink subframe set. For example, the K subframes in bundling-harqrrtt are respectively:

uplink subframe 2 and uplink subframe 7 of radio frame P, and uplink subframe 2 of radio frame P +1, as shown in fig. 10; or,
