Description

Indication method and device for multi-transmission mechanism mixed transmission

Technical Field

The present application relates to the field of mobile communications technologies, and in particular, to an indication method for multi-transmission mechanism hybrid transmission 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 within a slot, where each DM RS CDM group is associated with one beam of the 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.

The time-division multiplexing transmission mechanism has a large time delay and a low resource utilization rate, so that the reliability is improved on specific time and frequency resources by considering the combination of multiple transmission mechanisms.

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:

step 101, the high layer signaling contains first indication information, the first indication information identifies 1 TDM transmission mechanism;

the TDM transmission mechanism is TDMa or TDMb.

The terminal receives the first semi-static signaling (first indication information) and determines that the signaling is a first time division multiplexing mechanism and a second time division multiplexing mechanism. In the embodiments of the present application, TDMa is represented by a first time division multiplexing scheme, and TDMb is represented by a second time division multiplexing scheme.

102, the high-level signaling contains second indication information, and the second indication information identifies 1 FDM transmission mechanism;

the FDM transmission mechanism is FDMa or FDMb.

For example, the terminal receives the second semi-static signaling (second indication information) and determines that the signaling is the first frequency division multiplexing mechanism or the second frequency division multiplexing mechanism. In an embodiment of the present application, FDMa is represented by a first frequency division multiplexing scheme and FDMb is represented by a second frequency division multiplexing scheme.

Step 103, the downlink control signaling contains dynamic indication information, and the dynamic indication information is used for distinguishing the following two hybrid transmission mechanisms:

SDM and TDM hybrid transport mechanisms, TDM and FDM hybrid transport mechanisms. Here, the transport mechanism type of TDM is represented by the first indication information; the type of the FDM transmission mechanism is indicated by the second indication information.

It should be noted that, in addition to being used for distinguishing the hybrid transmission mechanism, the dynamic indication information may also be used for distinguishing the following three transmission mechanisms: space division multiplexing mechanism, frequency division multiplexing mechanism, time division multiplexing mechanism.

For example, the terminal receives the semi-static signaling indication as the first frequency division multiplexing mechanism and the second time division multiplexing mechanism, and the terminal receives the downlink control dynamic signaling indication as the TDM and FDM hybrid transmission mechanism, and then the terminal determines that the transmission mechanism is the hybrid transmission mechanism of the first frequency division multiplexing mechanism and the second time division multiplexing mechanism.

For another example, the terminal receives the higher layer signaling to determine that the frequency division multiplexing scheme is FDM a, the time division multiplexing scheme is TDM 4, and the SDM and the FDM are distinguished by the indicated number of DM RS CDM groups in the downlink control signaling DCI format 1_1, because SDM is indicated by different transmission configuration indication statuses (TCI statuses) for different layers of the whole resource, the number of CDM groups is 2, and FDM/TDM is indicated by different TCI statuses for different frequency resources and time resources, that is, the DM RS of the first CDM group uses the first TCI status, and the DM RS of the second CDM group uses the second TCI status. SDM and FDM can therefore be distinguished by the number of CDM groups indicated by physical layer control signaling. 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, 2 bits indicating an RV version of the transport block are used to indicate TDM, FDM, and TDM/FDM.

For example:

when the number of TCI states indications is 2, the indicated DM RS CDM number is 2, and the RV version (i.e., not enabled) of the non-scheduled transport block TB is indicated as 01, i.e., a multi-TRP space division multiplexing and time division multiplexing transmission scheme.

When the number of TCI states indications is 2, the indicated DM RS CDM number is 1, and the new data (i.e., not enabled) of the non-scheduled transport block TB is indicated as 11, i.e., a multi-TRP frequency-division multiplexing and time-division multiplexing transmission scheme.

And step 104, determining a mapping sequence, and sending or receiving downlink data.

When the downlink data is mapped to the transmission resource, the downlink data is mapped according to which order. The transmission resources include time, frequency, spatial resources, specifically described herein as slots, frequency units, DM RS CDM groups.

Fig. 2(a) to (f) show mapping methods of various orders of the hybrid transmission scheme. Specifically, the method comprises the following steps:

fig. 2(a) is a schematic diagram of a first order mapping of the SDM and TDM hybrid transmission scheme.

In a further optimized embodiment of the method, the dynamic indication information identifies that the hybrid transmission mechanism is a SDM and TDM hybrid transmission mechanism. When the downlink data is mapped to the transmission resource, the DM RS CDM group is occupied firstly, and then the occupation is occupied according to the sequence of the time slots. Each DM RS CDM group occupies one beam direction respectively; multiple beam directions are multiplexed every 1 slot.

For example, when the terminal transmission scheme is a spatial multiplexing and first/second time division multiplexing hybrid transmission scheme, two beam states (TCI state #1 and TCI state #2) received by the terminal are mapped in a first order, and the first order is mapped in a spatial order and then a temporal order.

Fig. 2(b) is a diagram illustrating a second sequential mapping of the SDM and TDM hybrid transmission scheme.

In another embodiment of the method alternative, the dynamic indication information identifies the hybrid transport mechanism as an SDM and TDM hybrid transport mechanism. When the downlink data is mapped to the transmission resource, the downlink data is occupied according to the time slot and then according to the sequence of the DM RS CDM group. The beam direction occupied by each DM RS CDM group changes along with time; the plurality of beam directions send downlink data in turn in sequence, and the rotation period of each beam direction occupies 1 time slot; further, when the last beam is finished, the first beam is started again.

For example, when the terminal transmission scheme is a hybrid transmission scheme of space division multiplexing and a second time division multiplexing scheme, two beam states (TCI state #1 and TCI state #2) received by the terminal are mapped in a second order, the second order is mapped in a time-first order and then a space order, and the beam mapping with time is a sequential mapping method.

Fig. 2(c) is a diagram illustrating a third sequential mapping of the SDM and TDM hybrid transmission scheme.

In another embodiment of the method alternative, the dynamic indication information identifies the hybrid transport mechanism as an SDM and TDM hybrid transport mechanism. When the downlink data is mapped to the transmission resource, the downlink data is occupied according to the time slot and then according to the sequence of the DM RS CDM group. The beam direction occupied by each DM RS CDM group changes along with time; and sending downlink data by a plurality of beam directions in turn, wherein the rotation period of each beam direction occupies a plurality of time slots until the sending of the last beam direction is finished, or starting from the first beam after the last beam is finished.

For example, when the terminal transmission scheme is a hybrid transmission scheme of space division multiplexing and a second time division multiplexing scheme, two beam states (TCI state #1 and TCI state #2) received by the terminal are mapped in a third order, the third order is mapped in a time-first and then space order, wherein the beam mapping over time is a cyclic mapping method.

Fig. 2(d) is a diagram illustrating a fourth sequential mapping of the TDM and FDM hybrid transmission scheme.

In another embodiment that is optional for the method, the dynamic indication information identifies that the hybrid transmission scheme is an FDM and TDM hybrid transmission scheme. Each frequency unit occupies a respective beam direction. When the downlink data is mapped to the transmission resource, the downlink data is occupied according to the sequence of the frequency unit and the time slot. In each time slot, a plurality of beam directions are multiplexed.

For example, when the terminal transmission scheme is a hybrid transmission scheme of the first frequency division multiplexing/second frequency division multiplexing and the first time division multiplexing/second time division multiplexing, two beam states (TCI state #1 and TCI state #2) received by the terminal are mapped in a fourth order, and the fourth order is mapped in an order of first frequency and then time.

Fig. 2(e) is a diagram illustrating a fifth sequential mapping of the TDM and FDM hybrid transmission scheme.

In another embodiment that is optional for the method, the dynamic indication information identifies that the hybrid transmission scheme is an FDM and TDM hybrid transmission scheme. The beam direction occupied by each frequency unit varies with time. When the downlink data is mapped to the transmission resource, the downlink data is occupied according to the sequence of the time slot and the frequency unit, and the used wave beam directions are the same in the same time slot. The plurality of beam directions send downlink data in turn in sequence, and the rotation period of each beam direction occupies 1 time slot; further, when the last beam is finished, the first beam is started again.

For example, when the terminal transmission scheme is a second frequency division multiplexing and first time division multiplexing/second time division multiplexing hybrid transmission scheme, two beam states (TCI state #1 and TCI state #2) received by the terminal are mapped in a fifth order, the fifth order is mapped in an order of first time and then frequency, wherein the beam mapping with time is a sequential mapping method.

Fig. 2(f) is a diagram illustrating a sixth sequential mapping of the TDM and FDM hybrid transmission scheme.

In another embodiment that is optional for the method, the dynamic indication information identifies that the hybrid transmission scheme is an FDM and TDM hybrid transmission scheme. The beam direction occupied by each frequency unit varies with time. When the downlink data is mapped to the transmission resource, the downlink data is occupied according to the sequence of the time slot and the frequency unit, and the used wave beam directions are the same in the same time slot. And sending downlink data in turn by a plurality of beam directions, wherein the rotation period of each beam direction occupies a plurality of time slots until the sending of the last beam direction is finished.

For example, when the terminal transmission scheme is a hybrid transmission scheme of the second frequency division multiplexing and the first time division multiplexing/second time division multiplexing, two beam states (TCI state #1 and TCI state #2) received by the terminal are mapped in a sixth order, the sixth order is mapped in an order of first time and then frequency, wherein the beam mapping over time is a cyclic mapping method.

When downlink data is mapped to a transmission resource, the mapping order of fig. 2(a) to (f) is the order of the first element and the second element, that is, the mapping order is occupied first by the first element and then by the second element. The specific meaning is that the second element is fixed as an initial value and is firstly arranged according to the sequence of the first element; then, after updating the second element value in the order of the second element, the second element is fixed to the updated value, and the second element is arranged … … in the order of the first element until the second element is fixed to its last value, in the order of the first element.

In the embodiment of fig. 2(a), the first element is a spatial or DM RS CDM group; the second element is time or a time slot; in the embodiments of fig. 2(b) - (c), the first element is time or time slot; the second element is a space or DM RS CDM group; in the embodiment of fig. 2(d), the first element is a frequency or frequency unit; the second element is time or a time slot; in the embodiments of fig. 2(e) - (f), the first element is time or time slot; the second element is a frequency or frequency unit.
