Some example embodiments may generally relate to uplink and downlink (UL/DL) multiple input multiple output (MIMO) enhancement method carried out by a terminal device, and a network entity. More specifically, certain embodiments of the invention introduce autonomous/implicit dynamic CORESETPoolIndex value switch for multi-downlink control information (M-DCI) based simultaneous multi-panel (STxMP) PUSCH transmission.
This section is intended to provide a background or context to the invention that is recited in the claims. The description herein may include concepts that could be pursued, but are not necessarily ones that have been previously conceived or pursued. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section.
UEs may be equipped with different number of TX antenna panels with different TX capabilities, e.g. number of TX antenna ports, max number of supported PUSCH layers, where one or more antenna panels may be used for full/partially/non-simultaneous multi-panel PUSCH transmissions to different TRPs associated with different CORESETPoolIndex values. To support different TX antenna panel capabilities, UE may be configured with two uplink sounding reference signal (UL SRS) resource sets where each set is configured with same or different number of resources with different number of antenna ports according to panel specific capabilities.
It has been agreed that, for M-DCI based STxMP PUSCH UE may be configured with one or more UL SRS resource sets with fixed association with TRPs (transmission reception points) via CORESETPoolIndex association. For M-DCI based STxMP PUSCH, UE may be configured with one or more UL SRS resource sets with fixed association with TRPs via CORESETPoolIndex association. However, fixed association between configured UL RS resource sets and CORESETPoolIndices leads to a problem that existing uplink DCI format may not be used to trigger M-DCI based STxMP PUSCH transmission to different TRPs. In other words, the fixed association may allow only higher layer reconfiguration of the association to support e.g. condition that the UE rotates and panels being directed to different TRPs than to ones they were directed at the time of the configuration of the association.
Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with some aspects of the present invention as set forth in the remainder of the present application with reference to the drawings.

For proper understanding of example embodiments, reference should be made to the accompanying drawings, as follows:
It will be readily understood that the components of certain example embodiments, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. The same reference designation may be used in multiple figures to refer to the same element or function. The following is a detailed description of some exemplary embodiments of systems, methods, apparatuses, and non-transitory computer program products for implicit switching of CORESETPoolIndex values for M-DCI based Simultaneous Multi-Panel PUSCH Transmission.
As discussed above, current specification or any prior art work does not provide solution to solve the problem related to fixed association between configured UL SRS resource sets and CoresetPoolIndices, leading to a problem that existing uplink DCI format may not be used to trigger M-DCI based STxMP PUSCH transmission to different TRPs.
This disclosure proposes a new implicit/autonomous M-DCI based STxMP PUSCH CORESETPoolIndexvalue switch for configured UL SRS resource sets. In one embodiment, the UE 202 may operate autonomously or in self-adaptation for the number of ports for an SRS resource set, which is associated with a CORESETPoolIndex that may be allowed. In some examples, the adaptation may be needed when the UE 202 rotates/changes its orientation with respect to the resource of the DL-RS configured in the indicated TCI states. In the adaptation, the UE 202 may determine that another antenna panel may be used for higher quality reception/transmission using an indicated TCI state such that the SRS resource set is configured to follow the TCI state.
In one embodiment, when the UE 202 performs autonomous adaptation, the UE 202 may implicitly switch to configured CORESETPoolIndexvalues (CPIv0, CPIv1 . . . ) between the configured UL SRS resource sets (R0, R1 . . . ), from a first association (R1/CPIv0 and R0/CPIv1) to a second association (R0/CPIv0 and R1/CPIv1) or vice versa, or between the at least two CORESETPoolIndexvalues (CPIv0 and CPIv1 . . . ) and the at least two sounding reference signal resource sets (R0, R1, . . . ).
In an alternative embodiment, downlink DCI may include a codepoint field for TCI state indication, which may be defined as implicit indication for a change of CORESETPoolIndexvalues (CPIv0 and CPIv1 . . . ) between the configured UL SRS resource sets (R0, R1 . . . ).
Upon detection of DCI including configured TCI state, the UE 202 may apply a priorization rule where the CORESETPoolIndex of the DCI indicating TCI states may apply for a UL SRS resource set corresponding to the indicated TCI state (e.g., R0/CPIv0, R1/CPIv1 . . . ), where the UL SRS resource set may be configured with FollowUnifiedTCIStateSRS-r17. In other words, as a result of the priorization rule, the UE may overwrite an existing value CORESETPoolIndexvalue with a CORESETPoolIndexvalue (e.g., from CPIv0 to CPIv1, or vice versa, or other combination of values) of the CORESET associated with the triggering DCI.
In one example, the UE 202 may perform autonomous adaptation. In an example, for a number of ports for the SRS resource in a SRS resource set: if the UE 202 determines that it is not capable of transmitting the SRS resource according to the capability (e.g., number of ports supported by the antenna panel that UE now switch to), then it may be allowed to reduce the number of ports supported by the capability. For example, if the SRS resource is a N-port resource, but the selected antenna panel has a capability of M (M<N), the UE 202 may be allowed to transmit the SRS resource with M number of ports.
If the SRS resource set includes SRS resource set with a configured port number N that is not higher than the capability M, the UE 202 may select to use the SRS resource up to M ports.
In step 2, (Optional step) UE 202 may determine that there is no pending or coming (within some certain time) capability value set index reporting instance/resources .
In step 3, UE 202 may decide to switch SRS resource set associations to coresetpoolindices/TRPs. As described, by switching configured CORESETPoolIndexvalues (CPIv0, CPIv1 . . . ) between the configured UL SRS resource sets (R0, R1 . . . ), from a first association (R1/CPIV0 and R0/CPIv1) to a second association (R0/CPIv0 and R1/CPIv1) or vice versa, such as between the at least two CORESETPoolIndex values (CPIv0 and CPIv1 . . . ) and the at least two sounding reference signal resource sets (R0, R1, . . . ).
In step 4, UE 202 may determine if there may be a need to lower the number of SRS antenna ports towards the TRP having a new associated SRS resource set, for example, from N lowered to M number of ports.
In step 5, UE 202 may transmit SRS transmissions according to the new determined associations (SRS0/R0/CPIV0 and SRS1/R1/CPIv1 . . . ), after the switching.
In one example, the autonomous adaptation may be triggered when the UE 202 determines that the DL-RS corresponding to the indicated TCI state may be received with higher quality using another antenna panel. A higher quality may refer to the another antenna panel measuring the DL-RS with quality that is X dB better than with a current antenna panel. The value X may be configured by a network entity (e.g., TRP1 212 or TP2 216) or may be predefined.
In one example, the autonomous adaptation may be triggered when the UE 202 determines that the antenna panel PN0 or PN1 has rotated. In one example, the autonomous adaptation may be triggered based on the UE implementation reason.
In one example, the autonomous adaptation may be triggered when the UE 202 determines that it has switched the panel PN0 used for an indicated TCI state 0. In one example, if even one of the panels (PN0 or PN1) may fulfill the autonomous adaptation criteria, UE202 is still allowed to perform it.
In one example, the UE 202 may determine that the above operation per antenna panel basis. In one example, the antenna panel (PN0 or PN1) may be referred as capability index value i.e. a DL RS may be associated with a specific capability index that has been reported, and if UE 202 determines that the SRS resource in a set would be transmitted with different capability (e.g. lower) that has been reported, the UE 202 may be allowed to adapt the port number for the SRS transmission. In one example, the UE behavior/whether the port number adaptation is allowed, may be configured by the network entity 212.

Modifications and configurations required for implementing functionality of certain example embodiments may be performed as routine(s), which may be implemented as added or updated software routine(s). Software routine(s) may be downloaded into the apparatus.
As an example, software or a computer program code or portions of it may be in a source code form, object code form, or in some intermediate form, and it may be stored in some sort of carrier, distribution medium, or computer readable medium, which may be any entity or device capable of carrying the program. Such carriers may include a record medium, computer memory, read-only memory, photoelectrical and/or electrical carrier signal, telecommunications signal, and software distribution package, for example. Depending on the processing power needed, the computer program may be executed in a single electronic digital computer or it may be distributed amongst a number of computers. The computer readable medium or computer readable storage medium may be a non-transitory medium.
In other example embodiments, the functionality may be performed by hardware or circuitry included in an apparatus (for example, apparatuses 310 and/or 320), for example through the use of an application specific integrated circuit (ASIC), a programmable gate array (PGA), a field programmable gate array (FPGAS), or any other combination of hardware and software. In yet another example embodiment, the functionality may be implemented as a signal, a non-tangible means that may be carried by an electromagnetic signal downloaded from the Internet or other network.
According to certain example embodiments, an apparatus, such as a node, device, or a corresponding component, may be configured as circuitry, a computer or a microprocessor, such as single-chip computer element, or as a chipset, including at least a memory for providing storage capacity used for arithmetic operation and an operation processor for executing the arithmetic operation.
The features, structures, or characteristics of example embodiments described throughout this specification may be combined in any suitable manner in one or more example embodiments. For example, the usage of the phrases “certain embodiments,” “an example embodiment,” “some embodiments,” or other similar language, throughout this specification refers to the fact that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment. Thus, appearances of the phrases “in certain embodiments,” “an example embodiment,” “in some embodiments,” “in other embodiments,” or other similar language, throughout this specification do not necessarily refer to the same group of embodiments, and the described features, structures, or characteristics may be combined in any suitable manner in one or more example embodiments. Further, the terms “cell”, “node”, “gNB”, or other similar language throughout this specification may be used interchangeably.
As used herein, “at least one of the following: <a list of two or more elements>” and “at least one of <a list of two or more elements>” and similar wording, where the list of two or more elements are joined by “and” or “or,” mean at least any one of the elements, or at least any two or more of the elements, or at least all the elements.
One having ordinary skill in the art will readily understand that the disclosure as discussed above may be practiced with procedures in a different order, and/or with hardware elements in configurations which are different than those which are disclosed. Therefore, although the disclosure has been described based upon these example embodiments, it would be apparent to those of skill in the art that certain modifications, variations, and alternative constructions would be apparent, while remaining within the spirit and scope of example embodiments. Although the above embodiments refer to 5G NR and LTE technology, the above embodiments may also apply to any other present or future 3GPP technology, such as LTE-advanced, and/or fourth generation (4G) technology.
This application claims priority to, and the benefits of the U.S. Provisional Application No. 63/488,957, filed on Mar. 7, 2023, which is herein incorporated by reference in its entirety.
