Description
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to an indication method for multiple transmission mechanisms and a device using the same.
Background
With the introduction of the large-scale antenna technology, multiple panels of a large-scale antenna of a base station can transmit simultaneously, and multiple base stations can also transmit simultaneously, which is called as a multi-TRP/multi-panel transmission technology. The same data is transmitted by using a plurality of beams by using a plurality of TRP/multi-panel, so that the reliability can be improved, and the method is used for scheduling low-delay high-reliability services. The main feasible mechanisms for multi-panel low-latency high-reliability scheduling include Space Division Multiplexing (SDM), Frequency Division Multiplexing (FDM), and Time Division Multiplexing (TDM) mechanisms. The method of Space Division Multiplexing (SDM) refers to overlapping time and frequency resources in a time slot, each set of DM RS ports is associated with one beam of multiple panels, and different coded bits are mapped to different layers. There are two mechanisms of frequency division multiplexing, one is that different coded bits from the same RV of multiple TRPs are mapped onto different sets of RBs, similar to frequency switching transmit diversity between multiple TRPs, but with limited diversity gain, called FDMa; the second way is that the difference from different RVs of multiple TRPs is sent with different coded bits mapped onto different groups of RBs, called FDMb, resulting in higher reliability, frequency multiplexing has better performance than space multiplexing due to no inter-TRP interference. The time division multiplexing mechanism comprises two mechanisms of time division repetition (TDMa) in a time slot and time division repetition (TDMb) in the time slot, different coding bits of multiple TRPs correspond to different time resource allocations, all sending moments use a uniform MCS, and RV/TCI states are the same or different at the sending moments. The time division multiplexing mode is a repeated combination of a time domain and a space domain, and can be used in a scene with higher requirements on reliability and resource utilization rate.
When 5 transmission mechanisms of space division, frequency division and time division multiplexing are supported, different transmission mechanisms need to be configured according to different delay requirements, reliability requirements and channel states, and corresponding signaling needs to be designed. The signaling includes RRC layer signaling, MAC layer signaling and physical layer control signaling, and the signaling overhead is to be reduced as much as possible.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a flow chart of an embodiment of the method of the present application.
The embodiment of the application provides a multi-transmission mechanism indication method, which comprises the following steps:
The high-level signaling comprises first indication information, and the first indication information identifies 1 TDM transmission mechanism; the higher layer signaling contains second indication information identifying 1 FDM transmission scheme.
Considering the two mechanisms of time division multiplexing and the two mechanisms of frequency division multiplexing, different mechanisms do not need to be changed frequently, and therefore specific time division multiplexing mechanisms and frequency division multiplexing mechanisms are indicated by RRC signaling. For example, the signaling of indicating the URLLC transmission repetition times by RRC signaling distinguishes the time division multiplexing mechanism 1 and the time division multiplexing mechanism 2; and indicating the frequency division multiplexing mechanism 1 and the frequency division multiplexing mechanism 2 by using the newly added RRC signaling.
The downlink control signaling contains dynamic indication information, and the dynamic indication information is used for distinguishing TDM, FDM and SDM transmission mechanisms.
Preferably, the dynamic indication information includes third indication information for identifying an SDM transmission mechanism, and further preferably, the third indication information is a quantity value of a DM RS CDM group.
For example, the indicated number of DM RS CDM groups in downlink control signaling DCI format 1_1 distinguishes between SDM and FDM, because SDM is different TCI states for different layers of the whole resource, so that a number of CDM groups of 2 indicates that the transmission scheme is SDM, and FDM/TDM is different TCI states for different frequency resources and time resources, that is, the DM RS of the first CDM group uses the first TCI state, and the DM RS of the second CDM group uses the second TCI state. Because the coding bits of different layers of the SDM are different, that is, the indicated beam directions are different, the DMRS port configurations in the downlink control signaling are different, and thus the SDM and FDM can be distinguished by the physical layer control signaling.

Preferably, the dynamic indication information includes fourth indication information for distinguishing TDM and FDM. Preferably, the fourth indication information is a reserved word in any one downlink control signaling. Or, the fourth indication information is multiplexed with idle indication information in the downlink control signaling. Preferably, the idle indication information is one of the following indication information: modulation coding scheme, new data indication, redundancy version. Preferably, the fourth indication information is 1 bit.
For example, DCI format 1_1 in 3GPP TS28.212 V15.5.0 release is used for scheduling PDSCH in 1 cell, and for transport block 1, the following indication information is available: modulation and coding scheme (Modulation and coding scheme), New data indicator (New data indicator) and Redundancy version (Redundancy version), there are also these three items of indication information for transport block 2 (which exists only when maxnrof codewordsschedule bydci is equal to 2).
For example, the reserved bits or unused bits in the downlink control signaling DCI format 1_1 indicate TDM and FDM, for example, if there is an un-enabled transport block, 1 bit of the new data indication indicating the transport block is used to indicate TDM and FDM.
As another example, three mechanisms for dynamic indication are as follows:
when the number of TCI status indications is 1, a single TRP transmission is performed.
When the number of TCI status indications is 2, and the indicated DM RS CDM number is 2, that is, the multi-TRP space division multiplexing transmission mechanism.
When the number of TCI status indications is 2, the indicated DM RS CDM number is 1, and when the new data indication for the scheduling transport block TB is 0, i.e., a multi-TRP time division multiplexing transmission scheme.
