Embodiment Construction

[0033] In the embodiment of the present invention, the TBS is extended based on the I MCS is the target code rate of the code rate corresponding to 25, the predetermined I TBS , physical resource block size, and the corresponding relationship with TBS, I MCS When the value is greater than 28, under the condition of the same physical resource block size, the TBS is greater than the TBS specified in the existing protocol. During the communication process, the UE side determines the I MCS When it is greater than 28, according to the I value greater than 28 MCS with I TBS The corresponding relationship, determine the I corresponding to the TB TBS ; Then according to the corresponding I of the TB TBS The physical resource block size corresponding to the TB indicated in the DCI, look up the I TBS , the physical resource block size, and the corresponding relationship with the TBS, and determine the TBS of the TB, so as to transmit data according to the determined TBS. Therefor...

Abstract

Disclosed are a communication method and device on a new carrier type (NCT) carrier. The method comprises: when IMCS corresponding to a scheduled TB is greater than 28, determining corresponding ITBS and a modulation level according to a correspondence among IMCS, the modulation level, and ITBS; searching for a correspondence among ITBS, the size of a PRB, and a TBS according to ITBS and the size of the PRB corresponding to the TB, and determining a TBS, so as to transmit data according to the determined TBS and the modulation level. The TBS in the correspondence is a TBS, among TBSs determined according to the existing protocol, that is not greater than a target TBS determined according to the size of the PRB in the correspondence and a target rate of the NCT carrier corresponding to ITBS, and has the value nearest to that of the target TBS; the target rate is greater than a rate of IMCS when IMCS in a non-NCT carrier is equal to 25. In this way, the resources on the NCT carrier can be fully utilized and the peak rate can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method and device on a carrier of a new carrier type. Background technique [0002] In Long Term Evolution (LTE) version 11 (Rel-11) and earlier versions, the Physical Downlink Control Channel (PDCCH) is multiplexed through the first N OFDM ( Orthogonal Frequency Division Multiplexing, OFDM) symbol transmission. The possible values ​​of N are 1, 2, 3, and 4, and N=4 is only allowed to appear in a system with a system bandwidth of 1.4 megahertz (MHz). Cell-specific Reference Signals (CRS) are transmitted in all downlink subframes that support Physical Downlink Shared Channel (PDSCH) transmission, and the system can support single-antenna port transmission (P 0 ), two-antenna port transmission (P 0 , P 1 ) or four-antenna port transmission (P 0 , P 1 , P 2 , P 3 ). [0003] In order to reduce system overhead, LTE Rel-12 discusses the definitio...
