Description

Method, system and device for transmitting and receiving transmission information The application is submitted to the Chinese Patent Office on September 07, 2012, the application number is 201210331635.0, and the invention name is

The priority of the Chinese Patent Application, which is incorporated herein by reference. TECHNICAL FIELD The present application relates to the field of wireless communication technologies, and in particular, to a method, system, and device for transmitting and receiving transmission information. Background Art In an LTE (Long Term Evolution) system, a turbo code encoder used for a traffic channel has a code rate of 1/3. In order to improve the coding efficiency, when a transport block (TB) is greater than 6144 bits, the transport block is subjected to code block partitioning to obtain a plurality of smaller code blocks (CBs). Each CB is independently coded, and the coding sequences of multiple CBs are cascaded to obtain the coding sequence of the TB.

The system bit stream, the first parity bit stream, and the second parity bit stream output by the turbo encoder are separately interleaved and sequentially collected by the bit collecting unit. The first interleaved system bit stream is sequentially input to the buffer, and then the interleaved first parity bit stream and the second parity bit stream are alternately input to the buffer, as shown in FIG.

In order to support efficient and flexible transmission methods, LTE Rel-8 (version 8) systems need to consider various transmission rate and modulation methods, and take into account HARQ (Hybrid Automatic Repeat reQuest) retransmission technology and chain. Road adaptive technology. To this end, the LTE system uses a puncturing or repeating method to extract a predetermined length bit sequence from the encoded bit stream, a process called rate matching.

In order to support user equipment of different capabilities, for certain levels of user equipment, the user equipment's memory cannot store all bits encoded by a larger code block. Therefore, before the rate matching, the base station first truncates the code sequence in the rate matcher according to the buffer size reported by the user equipment, that is, the number of soft channel bits (truncation) The coding sequence is recorded as the mother code), as shown in Figure 2: The base station performs rate matching based on the truncated mother code, that is, performs puncturing or repetition to obtain a sequence of information to be transmitted, where ^^ is a CB encoded sequence The length is the length of the mother code corresponding to one CB. The UE (User Equipment) side receives the information transmitted by the base station and performs decoding.

When the base station determines the length of the mother code in the rate matching process and the size of the storage space corresponding to each code block, the UE determines the number of fixed HARQ processes. If the uplink/downlink configuration of the TDD (Time Division Duplex) on a carrier changes dynamically, the number of corresponding HARQ processes on the carrier will also follow. Dynamic changes. If the length of the mother code in the rate matching and the size of the storage space corresponding to each code block at the UE end dynamically change with the TDD uplink/downlink configuration on the carrier, during the dynamic reconfiguration of the TDD uplink/downlink configuration, the base station is in a period of time. It is impossible to determine whether the UE has completed reconfiguration, that is, the base station cannot determine whether the UE works according to the previous TDD uplink/downlink configuration or the new TDD uplink/downlink configuration. When the understanding between the two is inconsistent, the base station determines the length of the mother code in the rate matching according to the number of HARQ processes corresponding to the TDD uplink/downlink configuration, and the UE performs the HARQ process corresponding to the other TDD uplink/downlink configuration. The number determines the length of the mother code in the solution rate matching, and the UE will not be able to decode correctly.

In summary, in the current system in which the TDD uplink/downlink configuration is dynamically changed and the system used for cross-band carrier aggregation and different TDD uplink/downlink configurations on different frequency bands, there will be a HARQ process between the network side and the user equipment side.
