Description

Technical Field

[0001] Example embodiments herein relate generally to wireless communications, and more particularly to simultaneous uplink (UL) transmissions (eg, using multiple antenna panels) from user equipment (UE) in a communication network. Background Art

[0002] A user equipment (UE) is a device that allows user access to network services. A UE can be connected to a wireless network, for example for network services, through a connection device such as a transmission reception point (TRP). A TRP is a transmit / receive (TX / RX) unit that can have a large number of TX / RX antenna elements that generate directional beams. The TRP is transparent to the UE because the UE only sees the mobility between the beams (beam mobility). Therefore, from the UE's perspective, the TRP can be regarded as one or more downlink reference signals that the UE is able to detect and measure, or associated with a set of signals and channels via a configured coreset pool index. For UEs that can support multiple uplink (UL) communications, such as through multiple antenna panels, the UE can communicate with multiple TRPs in a multi-TRP operation. For example, this allows the UE to communicate with two or more TRPs simultaneously. Antenna panels can be characterized and identified by logical indices, where each index can be associated with a certain capability / certain capabilities and / or parameters of the antenna panel (such as the number of antenna ports (supported by the antenna panel), Tx power / EIRP, the number of beams it can generate).

[0003] In the UL, the UE shall send control information to a TRP using the Physical Uplink Control Channel (PUCCH) and (user) data to the same TRP or to a different TRP using the Physical Uplink Shared Channel (PUSCH). Problems may arise when the UE communicates in the UL, for example, with multiple TRPs using its multiple antenna panels and sends UL information via different PUCCHs or via different PUSCHs or via both PUCCH and PUSCH.

Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred over other embodiments. All embodiments described in this detailed description are exemplary embodiments intended to enable those skilled in the art to make or use the invention, rather than to limit the scope of the invention as defined by the claims.

[0019] The exemplary embodiments herein relate to 3GPP New Radio (NR) physical layer development in Rel-18. More specifically, this document focuses on facilitating simultaneous PUCCH transmissions from two UEs transmitting antenna panels in a multi-DCI (m-DCI) multi-TRP (mTRP) scenario. Additional description of the exemplary embodiments is provided after describing a system in which the exemplary embodiments may be used.

[0020] Go to Figure 1 , which shows a block diagram of one possible non-limiting exemplary system in which exemplary embodiments may be practiced. A user equipment (UE) 110, a radio access network (RAN) node 170, and (multiple) network elements 190 are illustrated. Figure 1In the present invention, a user equipment (UE) 110 communicates wirelessly with a wireless network 100. The RAN node 170 is generally referred to as a gNB for 5G, but the RAN node is not limited to a gNB, as described in more detail below. The RAN node 170 has one or more TRPs 20, which may have different configurations depending on the radio access technology used. The UE 110 communicates with the gNB 170 via a wireless link 170. In one scenario, the UE 110 communicates with multiple TRPs 20 from the same gNB (gNB 170). In another scenario, another gNB 170-1 may be used, and the gNB may have its own set of one or more TRPs 20. If the UE communicates with the second gNB 170-1, the UE 110 uses the wireless link 110-1 for this purpose. In this scenario, it is assumed that the gNB 170 is a serving cell, and it is assumed that the gNB 170-1 is a secondary cell.

[0021] UE is a wireless device that can access a wireless network, typically a mobile device. UE 110 includes one or more processors 120, one or more memories 125, and one or more transceivers 130 interconnected by one or more buses 127. Each of the one or more transceivers 130 includes a receiver Rx 132 and a transmitter Tx 133. One or more buses 127 may be address, data, or control buses, and may include any interconnection mechanism, such as a series of lines on a motherboard or integrated circuit, optical fiber, or other optical communication device, etc. One or more transceivers 130 are connected to one or more antennas 128. One or more memories 125 include computer program code 123. UE 110 includes a control module 140, which includes one or both of parts 140-0 and / or 140-1, which can be implemented in a variety of ways. Control module 140 can be implemented as control module 140-0 in hardware, such as being implemented as part of one or more processors 120. Control module 140-0 can also be implemented as an integrated circuit or implemented by other hardware such as a programmable gate array. In another example, the control module 140 may be implemented as a control module 140-1, which is implemented as a computer program code 123 and executed by one or more processors 120. For example, the one or more memories 125 and the computer program code 123 may be configured to, together with the one or more processors 120, cause the user equipment 110 to perform one or more of the operations described herein. The UE 110 communicates with the RAN node 170 via the wireless link 111.

[0022] RAN node (e.g., gNB) 170 is a base station that provides access to wireless devices (such as UE 110) to wireless network 100. It is assumed that gNB 170 and 170-1 are similar, and only the circuit system of RAN node 170 is described. RAN node 170 can be, for example, a base station of 5G, also known as new radio (NR). In 5G, RAN node 170 can be a NG-RAN node, which is defined as a gNB or ng-eNB. gNB is assumed herein. gNB is a node (e.g., (multiple) network elements 190) that provides NR user plane and control plane protocol termination towards UE and is connected to 5GC via NG interface. ng-eNB is a node that provides E-UTRA user plane and control plane protocol termination towards UE and is connected to 5GC via NG interface. NG-RAN node can include multiple gNBs, which can also include a central unit (CU) (gNB-CU) 196 and (multiple) distributed units (DU) (gNB-DU). Note that the DU can include or be coupled to and control a radio unit (RU). DU (or RU) is an example of TRP 20. gNB-CU is a logical node that hosts the RRC, SDAP and PDCP protocols of a gNB, or the RRC and PDCP protocols of an en-gNB that controls the operation of one or more gNB-DUs. The gNB-CU terminates the F1 interface connected to the gNB-DU. The F1 interface is illustrated as reference numeral 198, but reference numeral 198 also illustrates the link between the remote elements of the RAN node 170 and the centralized elements of the RAN node 170, such as the link between the gNB-CU 196 and the gNB-DU (as TRP 20). The gNB-DU is a logical node that hosts the RLC, MAC and PHY layers of the gNB or en-gNB, and its operation is controlled in part by the gNB-CU. One gNB-CU supports one or more cells. One cell is supported by one gNB-DU. The gNB-DU terminates the F1 interface 198 connected to the gNB-CU. Note that the DU is considered to include the transceiver 160, for example, as part of the RU, but some examples in this regard may have the transceiver 160 as part of a separate RU, for example, under the control of the DU and connected to the DU. The RAN node 170 may also be an eNB (evolved NodeB) base station for LTE (Long Term Evolution), or any other suitable base station.

[0023] The RAN node 170 includes one or more processors 152, one or more memories 155, one or more network interfaces (N / WI / F) 161, and one or more transceivers 160 interconnected by one or more buses 157. Each of the one or more transceivers 160 includes a receiver Rx 162 and a transmitter Tx 163. The one or more transceivers 160 are connected to one or more antennas 158. The one or more memories 155 include computer program code 153. The CU 196 may include (multiple) processors 152, memories 155, and network interfaces 161. Note that the TRP 20 may also contain its own memory / memory and (multiple) processors, and / or other hardware, but these are not shown.

[0024] The RAN node 170 includes a control module 150, which includes one or both of the parts 150-1 and / or 150-2, which can be implemented in a variety of ways. The control module 150 can be implemented in hardware as the control module 150-1, such as being implemented as part of one or more processors 152. The control module 150-1 can also be implemented as an integrated circuit or by other hardware such as a programmable gate array. In another example, the control module 150 can be implemented as a control module 150-2, which is implemented as a computer program code 153 and executed by one or more processors 152. For example, one or more memories 155 and the computer program code 153 are configured to, together with the one or more processors 152, cause the RAN node 170 to perform one or more of the operations described herein. Note that the functionality of the control module 150 can be distributed, such as distributed between the DU (as the TRP 20) and the CU 196, or implemented separately in the DU.

[0025] One or more network interfaces 161 communicate over a network, such as via links 176 and 131. Two or more RAN nodes 170 may communicate using, for example, link 176. Link 176 may be wired or wireless or both, and may implement, for example, an Xn interface for 5G, an X2 interface for LTE, or other suitable interfaces for other standards.

[0026] The one or more buses 157 may be address, data, or control buses, and may include any interconnection mechanism, such as a series of wires on a motherboard or integrated circuit, optical fiber or other optical communication device, wireless channel, etc. For example, the one or more transceivers 160 may be implemented as a remote radio head (RRH) for LTE (as TRP 20) or a distributed unit (DU) for a gNB implementation for 5G (as TRP 20), where other elements of the RAN node 170 may be physically located at a different location from the RRH / DU, and the one or more buses 157 may be partially implemented as, for example, fiber optic cables or other suitable network connections for connecting other elements of the RAN node 170 (e.g., central unit (CU), gNB-CU) to the TRP (e.g., RRH / DU) 20. Reference numeral 198 also indicates these suitable (multiple) network links.

[0027] The wireless network 100 may include one or more network elements 190, which may include core network functions and provide connectivity to a data network 191 such as a telephone network and / or a data communication network (e.g., the Internet) via one or more links 181. Such core network functions for 5G may include (multiple) access and mobility management functions (AMFs) and / or (multiple) user plane functions (UPFs) and / or (multiple) session management functions (SMFs). Such core network functions for LTE may include MME (mobility management entity) / SGW (serving gateway) functions. These are merely exemplary functions that may be supported by (multiple) network elements 190, and it is noted that both 5G functions and LTE functions may be supported. The RAN node 170 is coupled to the network element 190 via a link 131. The link 131 may be implemented as, for example, an NG interface for 5G, or an S1 interface for LTE, or other suitable interfaces for other standards. The network element 190 includes one or more processors 175, one or more memories 171, and one or more network interfaces (N / WI / F) 180 interconnected by one or more buses 185. The one or more memories 171 include computer program code 173. The one or more memories 171 and the computer program code 173 are configured to, together with the one or more processors 175, cause the network element 190 to perform one or more operations.

[0028] The wireless network 100 can implement network virtualization, which is a process of combining hardware and software network resources and network functions into a single software-based management entity or virtual network. Network virtualization involves platform virtualization, which is usually used in conjunction with resource virtualization. Network virtualization is divided into external network virtualization or internal network virtualization. External network virtualization combines many networks or network parts into virtual units, while internal network virtualization provides network-like functions for software containers on a single system. Note that the virtualized entities generated by network virtualization are still implemented using hardware such as processors 152 or 175 and memories 155 and 171 to some extent, and such virtualized entities also produce technical effects.

[0029] Computer readable memories 125, 155, and 171 may be of any type suitable for the local technical environment and may be implemented using any suitable data storage technology, such as semiconductor-based memory devices, flash memory, magnetic memory devices and systems, optical memory devices and systems, fixed memory, and removable memory. Computer readable memories 125, 155, and 171 may be components for performing storage functions. Processors 120, 152, and 175 may be of any type suitable for the local technical environment and, as non-limiting examples, may include one or more of a general-purpose computer, a special-purpose computer, a microprocessor, a digital signal processor (DSP), and a processor based on a multi-core processor architecture. Processors 120, 152, and 175 may be components for performing functions such as control of UE 110, RAN node 170, and other functions described herein.

[0030] In general, various embodiments of the user device 110 may include, but are not limited to, a cellular telephone with wireless communication capabilities (such as a smart phone, a tablet computer, a personal digital assistant (PDA)), a portable computer with wireless communication capabilities, a vehicle with a modem device for wireless V2X (vehicle-to-everything) communication, an image capture device with wireless communication capabilities (such as a digital camera), a gaming device with wireless communication capabilities, a music storage and playback device with wireless communication capabilities, an Internet appliance (including an Internet of Things IoT device) allowing wireless Internet access and possible browsing, an IoT device with sensors and / or actuators for automation applications with wireless communication, a tablet computer with wireless communication capabilities, and a portable unit or terminal incorporating a combination of such functionality.

[0031] Therefore, having introduced a suitable but non-limiting technical context for implementing the exemplary embodiments, the exemplary embodiments will now be described in more detail.

[0032] As described above, problems may arise when a UE performs simultaneous transmissions to one or more TRPs via different PUCCHs, different PUSCHs or PUCCH+PUSCHs, such as, for example, in a multi-DCI (m-DCI) multi-TRP (mTRP) scenario, using multiple transmit antenna panels of the UE. An overview of the technical field and its possible problems is now provided.

[0033] Rel-18 is developing a method to enable the UE to transmit two PUCCHs simultaneously from different UE antenna panels, as described in the Rel-18 MIMO work item as follows [RP-213598]:

[0034]

[0035]

[0036] That is, there can be multi-panel uplink transmission to improve UL throughput / reliability, focusing on FR2 and multi-TRP, assuming up to two TRPs and up to two antenna panels. This requires the use of a unified TCI framework extension, and one option is to send PUCCH+PUCCH across two antenna panels in the same CC.

[0037] Note that from the UE's perspective, a TRP can be viewed as one or more downlink reference signals that the UE is able to detect and measure, or associated with a set of signals and channels via a configured coreset pool index.

[0038] This is an improvement over the Rel-17 unified TCI framework, which will now be described. Rel-17 introduced the unified TCI framework, which means that the TCI states that have so far provided QCL assumptions for the reception of DL signals and channels will also be used to provide spatial sources for the transmission of UL signals and channels. In addition, the unified TCI framework defines the concept of indicated TCI states. The indicated TCI state can be a joint DL and UL TCI state or a separate DL TCI state and a separate UL TCI state. The indicated TCI state provides the QCL source (DL) and spatial source (UL) for the group of downlink signals and channels and for the group of uplink signals and channels, respectively. In Rel-17, the UE can have one indicated joint DL and UL TCI state, or the UE can have one indicated DL TCI state and one indicated UL TCI state.

[0039] The unified TCI framework includes the following high-level features:

[0040] 1) The common TCI state for a group of signals and channels at a time (also called indicated TCI).

[0041] 2) The TCI state can be a joint DL / UL TCI state, a separate DL TCI state, and a separate UL TCI state.

[0042] 3) RRC configures a set (or pool) of joint TCI states and / or individual TCI states.

[0043] 4) MAC activates multiple (eg, 8) joint TCI states and / or individual TCI states.

[0044] a) Before the first indication, the first activated TCI state is the currently indicated TCI state. In more detail, before the UE receives the TCI selection (e.g., indication) in the DCI, the currently indicated TCI state is the first activated TCI state that has been activated by the MAC. The sequence order is that the TCI state is first configured in the RRC, then one or more states are activated by the MAC, and then the DCI selects / indicates from the activated states.

[0045] 5) The DCI indicates one of the activated TCI states as an indicated TCI state (which may be a common TCI state).

[0046] Regarding the TCI status indication based on DCI, the following agreements have been reached so far:

[0047] 1) DCI format 1_1 / 1_2 with and without DL allocation is used to carry TCI status indication.

[0048] 2) The UE confirms the indication via HARQ ACK.

[0049] 3) The application time of the beam indication, which can be the first time slot that is at least X ms or Y symbols after the last symbol of the confirmation of the joint or individual DL / UL beam indication.

[0050] 4)TCI field code point:

[0051] a) Joint, which may include TCI states for both DL and UL.

[0052] b) Individually:

[0053] i) a pair of DL TCI state and UL TCI state;

[0054] ii) DL TCI state (maintain current UL TCI state); or

[0055] iii) UL TCI state (maintain current DL TCI state).

[0056] Now that the Rel-17 unified TCI framework has been described, an additional technical overview is provided. The intention of PUCCH+PUCCH simultaneous transmission is that each PUCCH will be sent using a different panel (see Figure 2A ). Figure 2A The diagram illustrates multi-TRP communication using a UE with two antenna panels. The UE 110 has a first antenna panel 1 40-0 and a second antenna panel 2 40-1, which include antennas 128 (see Figure 1 ). UE 110 communicates with TRP#0 20-0 in the UL using UL TX beam #0 25-0 using antenna panel 1 40-0. TRP#0 20-0 communicates with UE 110 using DL beam 15-0 associated with DL-RS#0. There is TCI0 ​​30-0 indicating spatial source DL-RS#0. UE communicates with TRP#1 20-1 using UL TX beam #1 25-1 using antenna panel 2 40-1. TRP#1 20-1 communicates with UE 110 using DL beam 15-1 associated with DL-RS#1. There is TCI1 30-1 indicating spatial source DL-RS#1.

[0057] Note that the antenna panel can be characterized and identified by logical indices, where each index can be associated with a certain capability / certain capabilities and / or parameters of the panel (such as the number of antenna ports (supported by the antenna panel), Tx power / EIRP, the number of beams it can generate).

[0058] However, during operation, the UE can be rotated so that one panel serves two beam pair links between the UE and two receive TRPs. In other words, one panel can be facing two TRPs while the other UE panel is facing a direction where the TRPs are not located. Figure 2B , where due to the rotation 150, only antenna panel #0 40-0 points to two beams of TRP #0 and TRP #1, and antenna panel #1 40-1 faces the direction where there is no TRP 20. Therefore, in this case, in order to have a feasible beam pair link quality, one of the antenna panels will be used for both receive TRPs. In current NR systems, the network does not know which panel the UE is using or will use for a specific PUCCH transmission. That is, the UE only knows via the TCI state (e.g., in Figure 2A In the example, TCI 0 indicates a spatial source DL-RS #0) or an indicated TCI state including QCL-Type D RS (based on which the UE forms its transmit spatial filter) is provided with a spatial source reference signal.

[0059] Furthermore, when transmitting simultaneously with two panels, the total transmit power and / or EIRP may exceed the maximum allowed transmit power / EIRP and thus transmit power scaling may be required.

[0060] 3GPP TS 38.213 section 9.2.5 defines the UE behavior for overlapping PUCCH. However, the rules considered (including potential multiplexing, dropping and power scaling) do not take into account the mapping of PUCCH across multiple UE panels. Furthermore, as can be seen from the following specification excerpt, current NR (until Rel-17) does not support multiple simultaneous PUCCH transmissions triggered in a multi-DCI multi-TRP scenario:

[0061]

[0062] To address these issues, a framework for simultaneous uplink transmissions, such as, for example, PUCCH+PUCCH, or PUSCH+PUSCH, or mixed (e.g., PUCCH+PUSCH) transmissions, is considered herein, which provides UE rules or behaviors for the above different situations when the UE may need to drop one (multiple) of the simultaneous uplink transmissions or scale the transmit power / EIRP in some way. In one example, a multi-stage (e.g., two stages are the main example) method is proposed for the UE to determine its behavior to manage simultaneous uplink transmissions, such as overlapping two PUCCH transmission opportunities, or two PUSCH transmission opportunities, or two PUCCH+PUSCH transmission opportunities, and this is divided into two main steps.

[0063] 1) In a first step, a verification status of the association between the indicated TCI status and the different antenna panels of the UE is determined.

[0064] After the UE determines that there will be overlapping uplink transmissions (such as overlapping PUCCH+PUCCH transmissions), for example, the UE determines whether the UE can send two different PUCCHs simultaneously based on the currently indicated TCI state for different PUCCHs, i.e., using two (or more) different antenna panels of the UE.

[0065] In the determining step, the UE evaluates which transmit antenna panel is to be associated with which indicated TCI state based on the power threshold and the L1-RSRP measurement associated with the indicated TCI state. Based on this, the UE determines whether there is a one-to-one mapping between the indicated TCI state and different transmit antenna panels of the UE. For example, the one-to-one mapping defines or specifies that one or more indicated TCI states each correspond to a different transmit antenna panel in one or more transmit antenna panels associated with the UE.

[0066] When a one-to-one mapping is determined, the association state between the indicated TCI state and the different transmit antenna panels is defined or considered valid for overlapping uplink transmissions. Otherwise, the association state is defined or considered invalid for overlapping uplink transmissions.

[0067] That is, the UE maintains the indicated TCI states associated with different transmit antenna panels valid for overlapping uplink transmissions until the measured L1-RSRP-related DL resources of the indicated TCI state are higher than or equal to the (configured or predetermined) power threshold for the UE; otherwise, the UE determines that the state of the transmit antenna panel associated with the indicated TCI state is invalid for overlapping uplink transmissions. In this regard, the UE will determine whether the relevant beam pair links with different TRPs in the uplink are performed by two different antenna panels or by the same (single) antenna panel associated with the UE. The UE can achieve this by comparing the L1-RSRP measurements of each antenna panel, where each L1-RSRP measurement is performed for the DL RS of the indicated TCI state, which are used to characterize the beam pair links between the UE (antenna panel) and the TRP. In various embodiments, the UE can use two antenna panels to measure the DL RS (assuming that the UE will use the same beam as the downlink reception of the DL RS for uplink transmission and thus perform the measurement). The UE may compare the L1-RSRP results and evaluate whether the corresponding RSRP results are strong enough for the two beam pair links from different antenna panels, and then the UE determines that it can transmit from the two antenna panels simultaneously. Otherwise, the UE determines that the two beam pair links will be transmitted from the same antenna panel and therefore simultaneous transmission is not preferred.

[0068] 2) In a second step, the association state is defined or considered as invalid for overlapping uplink transmissions.

[0069] For example, if the UE cannot transmit two PUCCHs using different transmit antenna panels associated with the UE, the UE evaluates which of the PUCCHs to transmit as shown below.

[0070] a) If the priority indexes of the PUCCHs are not equal, the UE discards the PUCCH with the higher priority index. Note that a higher priority index indicates a lower priority.

[0071] b) Otherwise, the UE sends a PUCCH associated with a lower coresetPoolIndex. As is known, coresetPoolIndex is an index of a set of coresets (control resource sets) and is actually an index of a TRP. Here, priority sorting is performed based on coresetPoolIndex (where the lower the index, the higher the priority), although other indexes or information can also be used for priority sorting.

[0072] c) If the PUCCH transmission is associated with a CORESETpoolindex that is determined to be in a beam failure state or failed (the CORESET of CORESETPoolIndex is monitored using the BFD-RS set associated with CORESETpoolindex), the UE discards the PUCCH associated with the CORESETpoolindex of the failed BFD-RS set.

[0073] d) In one example, if one of the PUCCHs carries an SR transmission, the transmission may be prioritized over the other PUCCH.

[0074] i) Prioritization can be determined based on the SR type or the associated information provided by the SR.

[0075] ii) If SR is used for beam failure recovery / LBT failure indication, SR can be given priority for transmission.

[0076] In one example, if one of the PUCCHs carries A / N feedback for a DL retransmission, it may be prioritized, for example, over a PUCCH carrying A / N feedback for a first transmission.

[0077] In one example, the priority may be based on the time type of the PUCCH transmission, eg, aperiodic / scheduled PUCCH may be prioritized over periodic PUCCH.

[0078] This concludes the discussion of Step 2.

[0079] Regarding these steps, if the UE is able to send two PUCCHs, the UE estimates the total Tx power / EIRP required as shown below.

[0080] i) If the required Tx power / EIRP does not exceed the allowed maximum value, the UE sends two PUCCHs.

[0081] ii) Otherwise, the UE performs TX power scaling using the following options (select one of the options to use):

[0082] A) Perform equal power scaling;

[0083] B) performing unequal power scaling such that the UE performs power scaling on PUCCH associated with a higher coresetPoolIndex; or

[0084] C) Drop the PUCCH associated with a higher coresetPoolIndex.

[0085] In the above, although overlapping PUCCH+PUCCH transmissions are considered with respect to how the UE determines whether the UE can transmit simultaneously, i.e., using two (or more) different transmit antenna panels, based on the currently indicated TCI state of the overlapping transmissions, the same may be applied to other overlapping uplink transmissions, such as, for example, overlapping PUSCH+PUSCH or PUCCH+PUSCH transmissions from a UE using two (or more) different transmit antenna panels associated with the UE.

[0086] In one embodiment, if the UE determines that there is a possibility of overlapping uplink transmissions, such as, for example, PUCCH+PUCCH or PUSCH+PUSCH or PUCCH+PUSCH transmissions from two (or more) different transmit antenna panels of the UE, the UE may trigger (e.g., non-periodic or dynamic) uplink reporting, for example, where the report may include an indication that more than one uplink transmission / TCI state of the UE is associated with the same UE antenna panel associated with the UE.

[0087] In one example, for example, for overlapping PUCCH+PUCCH transmissions, priority may be given to the PUCCH that starts earlier in time. Here, the PUCCH transmissions partially overlap, and the first PUCCH transmission in time may continue while the other PUCCH transmission is discarded. For overlapping PUCCH+PUSCH transmissions, priority may be given to the PUCCH or PUSCH that starts earlier in time. Here, the PUCCH+PUSCH transmissions partially overlap, and the first PUCCH or PUSCH transmission in time may continue while the other transmission is discarded. Similarly, for overlapping PUSCH+PUSCH transmissions, priority may be given to the PUSCH that starts earlier in time. Here, the PUSCH transmissions partially overlap, and the first PUSCH transmission in time may continue while the other PUSCH transmission is discarded.

[0088] In one example, for overlapping PUCCH+PUCCH transmissions, PUCCHs with repetitive operation in time (PUCCH with TDM towards one TRP or two TRPs) or with a higher number of repetitions may be de-prioritized. That is, a single PUCCH transmission takes precedence over a PUCCH transmission that is part of a repeated PUCCH transmission. Here, a PUCCH repetition may have at least one other repetition instance that may not overlap with a PUCCH transmission towards other TRPs.

[0089] Note that multiple TRPs are used as the main example in this article, but the technology described in this article is not limited to multiple TRPs. In addition, although the unified TCI framework is the main example, this specification only uses unified TCI as an example. In addition, although some examples use antenna panels, other antenna systems in the UE that can communicate with multiple receiving points in the UL can also be used.

[0090] Referring to Figure 3, it is divided into Figure 3A and Figure 3B , which is a logical flow diagram of simultaneous uplink transmissions in a communication network. The example involves multi-level rules for simultaneous UL (e.g., PUCCH+PUCCH or PUSCH+PUSCH or PUCCH+PUSCH) transmissions for multiple TRP scenarios under a unified TCI framework. The figure also illustrates the operation of one or more exemplary methods according to the exemplary embodiments, the results of the execution of computer program instructions embodied on a computer-readable memory, the functions performed by logic implemented in hardware, and / or the interconnected components for performing the functions. The blocks in the flow diagram are executed by UE 110. Figure 3 contains much of the above material, but in the form of a logical flow diagram.

[0091] In box 305, the UE determines that there will be (e.g., at least partially) overlapping uplink transmissions. Note that this overlap is primarily considered to be in time, although frequency may also play a role. These uplink transmissions may be PUCCH+PUCCH, PUSCH+PUSCH, or mixed transmissions (e.g., PUCCH+PUSCH). In box 310, the UE identifies or detects whether it can transmit simultaneously in two indicated TCI states (which are beam pair links of two different UE transmit antenna panels). Box 330 further defines box 310. Box 330 indicates that in the determination step of 310, the UE evaluates which transmit antenna panel to associate with which indicated TCI state based on L1-RSRP measurements. For example, the UE may attempt to maintain the indicated TCI states associated with different transmit antenna panels, but there may be a threshold, and if the RSRP value is below the threshold, the UE determines that the association is invalid for overlapping uplink transmissions. It should be noted that the terms "identifying", "detecting" or "determining" in these steps are assumed to be similar or identical and indicate that the UE is making a decision as to whether the UE can send two (or more) transmissions simultaneously in the uplink.

[0092] If not (block 310=No), the UE determines in block 315 whether the priority indexes are equal, where the priority index here refers to the priority indexes to different channels explicitly configured in the RRC. If the priority indexes are not equal (block 315=No), in case of overlapping channel (e.g., PUCCH+PUCCH, PUSCH+PUSCH, or hybrid PUCCH+PUSCH) transmissions, the UE drops the channel with the higher priority index in block 320. If the priority indexes are equal (block 315=Yes), the UE sends the channel associated with the lower coresetPoolIndex and drops the other channel in block 325.

[0093] In block 310, if the UE determines that it can transmit simultaneously in both indicated TCI states (block 310=yes), flow continues to block 335, where the UE determines whether the total Tx power or EIRP will exceed the allowed maximum value for the UE. If not (block 335=no), the UE transmits information on both channels in block 340. If yes (block 335=yes), the UE performs power scaling or drops the channel associated with the higher coresetPoolIndex in block 345.

[0094] Figure 4 is a logic flow diagram performed by a UE for simultaneous uplink transmission in a communication network. Figure 4Also illustrated are the operations of one or more exemplary methods according to exemplary embodiments, the results of execution of computer program instructions embodied on a computer readable memory, functions performed by logic implemented in hardware, and / or interconnected components for performing functions.

[0095] In step 1.a, the UE performs identification or detection that simultaneous transmissions of at least two uplink channels from the device will at least partially overlap. In step 1b, the UE performs management of simultaneous transmissions of at least two uplink channels based on the identification or detection. Hereinafter, steps 1a and 1b are collectively referred to as step 1.

[0100] Step 6. This step is related to step 4 or 5, wherein managing simultaneous transmissions further comprises:

[0101] In response to the mapping being a one-to-one mapping in which the one or more indicated TCI states each correspond to a different transmit antenna panel of the one or more transmit antenna panels of the apparatus, deeming the mapping to be valid for simultaneous transmission for at least two uplink channels; and

[0102] Otherwise, the mapping is considered invalid for simultaneous transmission of at least two uplink channels.

[0103] Step 7. This step refers to any one of steps 4 to 6, wherein managing simultaneous transmissions further comprises:

[0104] In the case of a one-to-one mapping, the association is maintained until a power threshold and a layer 1 reference signal received power measurement associated with one or more indicated TCI states is above or equal to the power threshold, wherein the one or more indicated TCI states each correspond to a different transmit antenna panel among the one or more transmit antenna panels of the device.

[0105] Step 8. This step relates to step 6 or 7, wherein managing simultaneous transmission further comprises: performing simultaneous transmission of at least two uplink channels from the device based on a total transmission power required for the simultaneous transmission.

[0106] Step 9. This step relates to any one of steps 6 to 8, wherein the required total transmit power is lower than the maximum allowed transmit power for the device to transmit at least two uplink channels.

[0107] Step 10. This step involves any one of steps 6 to 8, wherein managing simultaneous transmission also includes: in response to the required total transmission power exceeding the maximum allowed transmission power for the device to transmit at least two uplink channels, performing simultaneous transmission of at least two uplink channels by transmission power scaling.

[0108] Step 11. This step relates to any one of steps 1 to 10, wherein an uplink report is triggered in response to the identification or detection.

[0109] Step 12. This step is related to step 11, wherein the report includes an indication that more than one uplink transmission of the UE or more than one TCI state is associated with the same UE antenna panel associated with the UE.

[0110] Step 13. This step relates to any one of steps 1 to 12, wherein managing simultaneous transmissions further comprises: in response to transmissions of the at least two uplink channels partially overlapping, prioritizing transmissions of the at least two uplink channels.

[0111] Step 14. This step is related to step 13, wherein the priority ranking is based on a repetitive operation associated with at least one of the at least two uplink channels.
