Description

Method and device for configuring PUSCH transmission, communication device, and storage medium for implementing the invention name formulated by ISA according to detail 37.2

Technical Field

The present disclosure relates to the field of wireless communications, but not limited to the field of wireless communications, and in particular, to a method and apparatus for configuring a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), a communication device, and a storage medium.

Background

In order to improve coverage at the cell edge, providing a more balanced quality of service in the service area, coordinated multipoint is still an important technical means in New Radio (NR) systems.

From the network morphology perspective, network deployment in a manner of centralized processing of a large number of distributed access points and baseband is more beneficial to providing balanced user experience rates, and significantly reduces time delay and signaling overhead caused by handover.

With the rise of frequency bands, relatively dense access point deployment is also required from the viewpoint of ensuring network coverage. In the high frequency band, as the integration level of the active antenna device increases, the modularized active antenna array is more preferred. The antenna array of each transmitting point (Transmission Reception Point, TRP) can be divided into a plurality of relatively independent antenna panels, so that the form and the port number of the whole array surface can be flexibly adjusted along with deployment scenes and service requirements.

And the antenna panels or TRPs can be connected by optical fibers, so that more flexible distributed deployment can be performed.

In the millimeter wave band, the blocking effect generated by obstacles such as human bodies or vehicles is more remarkable along with the reduction of the wavelength.

In this case, from the viewpoint of ensuring link connection robustness, transmission/reception may be performed from a plurality of beams at a plurality of angles by using cooperation between a plurality of TRPs or panels, thereby reducing adverse effects caused by blocking effects.

As shown in fig. 2, an embodiment of the present disclosure provides a PUSCH transmission configuration method, where the method includes:

s1110: different TCIs are configured for different antenna panels of a terminal aiming at NC-JT of the PUSCH, and the NC-JT of the PUSCH is carried out by adopting FDM for different antenna panels.

The PUSCH transmission is configured to: the PUSCH transmission for a terminal having two or more antenna panels is configured.

In some embodiments, the communication devices that configure different TCIs for different antenna panels of the terminal may be base stations.

Illustratively, the terminal includes two antenna panels, which may be oppositely oriented. One of the antenna panels includes one or more antenna elements thereon.

In the disclosed embodiments, different antenna panels of a terminal may be used to transmit data to different TRPs of a base station.

As shown in fig. 3, one terminal has two antenna panels, and can simultaneously transmit data to TRP1 and TRP2 of a base station.

When the terminal executes NC-JT of PUSCH, joint shaping of wave beams transmitted by a plurality of antenna panels is not needed, each antenna panel can independently pre-encode data streams transmitted by the terminal, and mutual coordination of phases among the antenna panels is not needed. And when the terminal performs NC-JT of the PUSCH, the data stream is only mapped to part of antenna panels of the terminal, and is not required to be mapped to all the antenna panels.

Different antenna panels have different TCIs (i.e., the different antenna panels of the terminal are configured with independent TCI states), then the beam directions of the transmit beams of the different antenna panels are individually indicated by the respective corresponding TCIs.

Assuming that the number of PUSCH data transmission layers is 4, the two antenna panels of the terminal shown in fig. 4 are C-JTs of TRP1 and TRP2, respectively, where the number of data transmission layers sent by the multiple antenna panels is the same, and each data transmission layer needs to be transmitted.

In the embodiment of the disclosure, different antenna panels of the terminal use FDM to perform NC-JT of PUSCH, and then the carrier frequencies used by the antenna panels are different.

Illustratively, antenna panel 1 of the terminal uses a carrier of frequency 1 and antenna panel 2 of the terminal uses a carrier of frequency 2. The frequency 1 is not equal to the frequency 2, and a certain frequency interval is formed between the frequency 1 and the frequency 2, so that the interference of the antenna panel for simultaneously receiving and transmitting signals is reduced, and the communication quality is ensured.

As shown in fig. 5: the FDM is performed by taking the data transmission of two antenna panels of the terminal as an example. One antenna panel of the terminal uses beam 1 and the other antenna panel uses beam 2; the beam directions of beam 1 and beam 2 are indicated by the respective corresponding TCIs. In fig. 5, the vertical axis represents the frequency domain axis, and the horizontal axis represents the time axis. It can be seen that beam 1 and beam 2 use the same time domain resources in the time domain and different frequency domain resources in the frequency domain, implementing NC-JT for FDM-based PUSCH. Illustratively, the time domain resources used by beams 1 and 2 may be one or more symbols, one or more sub-slots, or one or more time slots.

If multiple antenna panels of the terminal perform NC-JT transmission of PUSCH simultaneously according to the respective corresponding TCIs, throughput of the communication system can be improved, and transmission reliability is improved.

And the TCI corresponding to the antenna panel and the PUSCH transmission between different antenna panels are carried out by adopting FDM, and the PUSCH transmission carried out by adopting NC-JT belongs to the PUSCH transmission configuration.

In one embodiment, the frequency domain resources allocated to the terminal may be contiguous, i.e., RBs configured for the same terminal may be continuously distributed in the frequency domain.

In one embodiment, one or more of the PUSCH transmission configurations may be sent by the base station to the terminal through one or more network signaling, or the PUSCH transmission configuration may be pre-agreed by a network protocol.

The network signaling includes, but is not limited to: RRC signaling, MAC CE, and/or DCI.

In some embodiments, the time domain resources associated with different TCIs are the same and the associated frequency domain resources are different.

In the embodiment of the disclosure, the different antenna panels of the terminal adopt FDM, and then the NC-JT of the PUSCH of the different antenna panels of the terminal are configured on the same time domain resource, so that the different antenna panels of the terminal can transmit data to different TRPs of the base station at the same time, and the transmission bandwidth and the transmission rate of the terminal are improved.

In one embodiment, one of the TCIs associates one set of resource blocks RBs, wherein one of the set of RBs comprises: one or more RBs. The PUSCH transmission configuration of the terminal, in which one TCI is associated with one RB set of resource blocks, may be configured by the base station through network signaling or configured by the terminal according to protocol conventions.

In the embodiment of the disclosure, when NC-JT of PUSCH is performed, granularity of frequency domain resource scheduling is set by RB. The RB set includes at least one RB. Since the TCI has a corresponding relationship with the antenna panel of the terminal, the RB set associated with the TCI is configured to the corresponding antenna panel.

In some embodiments, the data transport layer sets associated with different TCIs are the same, wherein one of the data transport layer sets comprises: one or more data transport layers. The terminal sets the same PUSCH transmission configuration for the data transmission layer associated with different TCIs, and the terminal can be configured by the base station through network signaling or according to protocol convention.

With NC-JT, different antenna panels may not be associated to all data transmission layers, but may be associated with only a portion of the data transmission layers. In the embodiment of the present disclosure, one TCI-associated data transmission layer is embodied in the form of a set, and then in the corresponding PUSCH transmission configuration, the set of data transmission layers may be embodied in the set identifier of the set of data transmission layers. One set of data transport layers includes at least one data transport layer.

In some embodiments, one demodulation reference signal (Demodulation of reference signal, DMRS) port combination of the terminal associated with different TCIs is the same;

Wherein one of the DMRS port combinations includes one or more DMRS ports of the terminal.

The PUSCH transmission configuration of the DMRS port combination associated with the TCI of the terminal can be configured by the base station through network signaling or configured by the terminal according to protocol convention.

In the embodiment of the present disclosure, NC-JT is adopted, multiple TCIs of a terminal may be associated with the same DRMS port combination. Illustratively, a DMRS port included in a DMRS port combination herein may be part or all of a terminal's ports.

For example, the terminal has two antenna panels and includes 4 DMRS ports, and TCIs corresponding to the two antenna panels are associated with the 1 st to 3 rd DMRS ports of the terminal.

In some embodiments, the maximum number of data transmission layers adopted by each antenna panel of the terminal performing the NC-JT is: min { N-p1, N-p2, … N-pX };

wherein, X is the total number of antenna panels of the terminal; the N-px is the maximum data transmission layer number supported by the x-th antenna panel; and X is a positive integer less than or equal to X.

Since the NC-JC using PUSCH is not used for joint shaping, the maximum number of data transmission layers supported by the antenna panel may depend only on the maximum number of data transmission layers supported by the antenna panel itself.

For example, when PUSCH transmission configuration is performed, the actual data transmission layer number associated with each TCI is determined according to the maximum data transmission layer number supported by the antenna panel corresponding to the TC.

The PUSCH transmission configuration of the association relationship between the antenna panel and the maximum data transmission layer number of the terminal can be configured by the base station through network signaling or configured by the terminal according to protocol convention.

In some embodiments, different antenna panels of the terminal use a single redundancy version RV for a single TB transmission of NC-JTs of the PUSCH, where one of the TBs corresponds to one Codeword (CW).

The terminal uses a single redundancy version RV to carry out the PUSCH transmission configuration of the single TB transmission of the NC-JT of the PUSCH, and the PUSCH transmission configuration can be configured by a base station through network signaling or can be configured by the terminal according to protocol convention.

And if different antenna panels are associated with a single RV, TCIs corresponding to a plurality of antenna panels of the NC-JC of the terminal for carrying out PUSCH can be associated with the same RV.

In one embodiment, multiple antenna panels of the terminal implement NC-JT of the PUSCH by different ones of the antenna panels using a single modulation and coding strategy, MCS.

In the disclosed embodiment, multiple antenna panels use the same MCS for NC-JT of PUSCH. If the terminal uses the same MCS to perform NC-JT of PUSCH, the base station side may use the same MCS to perform processing of received data of NC-JT of PUSCH.

In some embodiments, the frequency domain resources of the terminal are equally allocated among different of the antenna panels.

Notably: the PUSCH transmission configuration of the terminal, which is the frequency domain resource equally distributed among different antenna panels, can be configured by the base station through network signaling or configured by the terminal according to protocol convention.

In the embodiment of the disclosure, the multiple antenna panels of the terminal perform NC-JT of PUCCH with FDM, and at this time, there are multiple frequency domain resource number allocation manners used by FDM, one of which is to perform balanced allocation among the multiple antenna panels. If balanced allocation is adopted, the frequency domain resources used by different antenna panels of the terminal are equal in quantity.

Specifically, when the multiple antenna panel resources of the terminal are distributed in a balanced manner, the frequency domain resources of a single antenna panel are distributed continuously in the frequency domain, or the frequency domain resources used by the multiple antenna panels are distributed in a staggered manner in the frequency domain.

In one embodiment, the terminal uses multiple redundancy versions RV to enable different codeword CW transmissions of NC-JTs of the PUSCH, where one of the CWs corresponds to one transport block TB.

In some embodiments, multiple antenna panels of the terminal implement NC-JT of the PUSCH using multiple MCSs.

Notably: the terminal uses a plurality of MCSs to realize the PUSCH transmission configuration of the NC-JT of the PUSCH, and the terminal can be configured by a base station through network signaling or according to protocol convention.

Of course, different antenna panels use multiple MCSs to implement NC-JT of PUSCH, one implementation is: different antenna panels can use different MCSs for NC-JT of PUSCH; another implementation is: different antenna panels use the same multiple MCSs for NC-JT of PUSCH. If multiple antenna panels use multiple MCSs to perform NC-JCs of PUSCH, the identity of the MCS associated with the TCI corresponding to each antenna panel may be multiple.

In some embodiments, the number of frequency domain resources of NC-JT of the PUSCH performed by the antenna panel has an association with the MCS of NC-JT of the PUSCH performed by the corresponding antenna panel.

In some embodiments, precoding matrices used by the plurality of antenna panels are independent for NC-JT of the PUSCH.

The antenna panel performs NC-JT of PUSCH, and then the multiple antenna panels may perform precoding using the precoding matrix that is most suitable for each.

At this time, TCIs corresponding to different antenna panels are associated with matrix identifications of the respective precoding matrices.

Notably: the terminal, which is NC-JT for the PUSCH, and the PUSCH transmission configuration with independent precoding matrixes used by a plurality of antenna panels, can be configured by a base station through network signaling or configured by the terminal according to protocol convention.

In some embodiments, the TCI comprises:

combining TCI;

independent TCI;

spatial relationship information;

a resource indicator SRI of a sounding reference signal (Sounding reference signals, SRS).

Under a unified TCI framework configuration, TCI may include: combined TCI and independent TCI.

A joint TCI may be used to determine the direction of the upstream and downstream beams. The uplink beam is used for uplink transmission, and the downlink beam is used for downlink reception.

The independent TCI can then be used for the direction of the upstream or downstream beam in general. The beam direction of the uplink beam, the independent TCI may be indicated by the UL TCI.

In some embodiments, the indication information of the TCI has a plurality of TCI fields; and the TCI domain indicates the TCI corresponding to the antenna panel of the terminal.

If TCI under the unified TCI framework configuration is not used, spatial relationship information (spatialrelationship info 1/2) may be used.

If the uplink beam directions of the different antenna panels of the terminal are not indicated by the combined TCI or the independent TCI, the uplink beam directions of the different antenna panels of the terminal can be indicated by adopting the spatial relationship information.

SRS can be used for estimating downlink channel and shaping downlink beam. The SRI of the SRS may have a correspondence relationship with the direction of the uplink beam. Thus, the SRI of the SRS is one of the TCIs corresponding to the different antenna panels of the terminal.

Illustratively, the terminal has two antenna panels, and the TCI is indicated by two TCI fields, one TCI field indicating that one day panel is to be carried.

In another embodiment, the indication information of the TCI has a TCI field; the code point of the TCI field indicates the TCIs of a plurality of antenna panels of the terminal.

At this time, the TCI indication information includes a unified TCI field, which includes one or more bits, and different bit values of the bits are different code points. The different code points of one TCI field may indicate the TCIs of multiple antenna panels of the terminal.

Illustratively, the TCI field may divide a plurality of subfields, one subfield indicating the TCI of one antenna panel. A subfield may comprise one or more bits.

Also illustratively, one code point of the TCI field corresponds to a combination of multiple TCIs at the same time.

Uplink simultaneous transmission of multiple antenna panels (multi-panel)/multiple TRPs (multi-TRP) of a base station for supporting higher throughput and more reliable transmission performance.

Embodiments of the present disclosure consider how to implement FDM transmission scheme definition and beam indication supporting MP/MTRP based on single (single) DCI scheduled PUSCH transmission or scheduling-free PUSCH transmission, with the following specific methods:

Consider a state value (state) based on a unified TCI framework (unified TCI framework) configured for N TCIs suitable for simultaneous transmission by a terminal.

If the MP/MTRP beam consistency is established, the TCIs of different panels of the terminal may be indicated by N different joint TCIs.

If the MP/MTRP beam consistency is not satisfied, the TCIs of each antenna panel in PUSCH transmission for the terminal may be indicated together by N independent (separate) UL TCIs.

Assuming that the terminal has only two antenna planes, i.e. the number of antenna panels n=2 of the terminal, the terminal will be configured with 2 TCIs, here abbreviated as TCI1 and TCI2.

Each TCI corresponds to a transmit/receive beam of one antenna panel of the terminal and faces one transmit TRP direction, and each TCI contains a different QCL Type D source reference signal (QCL Type-D source RS) may include at least one of the following:

channel state information reference signals (CSI-RS, channel State Information Reference Signal);

the synchronization signal broadcasts a channel Block (SSB, synchronous Signal/PBCH Block).

The terminal uses an antenna panel corresponding to the QCL Type-D source RS contained in the TCI to transmit and receive. When the unified TCI framework is not configured, the SRI combination indicated spatialReconstate info1/2 is used.

For the support of the number of transmission layers actually corresponding to each TCI, the terminal capability needs to be considered, and the maximum port number or the maximum supported layer number contained in the maximum SRS resource supported by different antenna panels may be different according to the report of the terminal, that is, the maximum layer number supported by different antenna panels corresponds to the antenna panel 1 and the antenna panel 2 and is n_p1 and n_p2 respectively.

The FDM transmission based on the S-DCI may implement transmission of multiple uplink transmission points (MTRP) by:

mode one: the PUSCH transmission configuration of NC-JT of PUSCH by multiple antenna panels of the terminal based on FDM may be as follows:

mapping and transmitting data of 1 TB on non-overlapping frequency domain resources in the same time slot, wherein each TCI is associated with 1 group of RB sets in an allocated bandwidth; the total number of TCIs contained on each slot/symbol is n=2;

the plurality of TCIs correspond to a set of DMRS ports or port combinations, and the number of supported maximum total data transmission layers is: 4 layers.

The number of data transmission layers actually configured is not more than min { n_p1, n_p2}.

A single RV is used to achieve single CW transmission.

Support a single MCS;

in one approach, frequency domain resources are equally allocated between multiple antenna panels if a single MCS is used.
