[0046] The rapid growth of mobile communications and technological advancements have led to greater demands for capacity and peak data rates. Other factors, such as energy consumption, equipment cost, spectrum efficiency, cost per bit delivered, throughput, and latency, are also crucial for the success of future wireless networks.

[0047] In this disclosure, the term "transmission unit" (TRU) refers to a unit from which data can be transmitted. Coordinated transmissions can be performed between multiple TRUs, regardless of whether the coordinated transmission originates from a mobile station (UE) communicating with two or more non-co-located transmission points (in this example, TRUs include transmission points (TRPs) 104 and 106, such as...). Figure 1A and Figure 1B As shown), or a mobile station (UE) 102 communicating with any combination of antenna elements within two or more antenna panels or a single transmission point (in this example, the TRU includes an antenna array 140, such as...). Figure 1A-1 and 1B-1 (As shown).

[0048] The term "transmission technology" refers to different multi-antenna schemes, such as diversity, multiplexing with different maximum support layers, beamforming, or transmissions with one or more PDCCH / PDSCH or from one or more TRUs.

[0049] The term “exemplary” is used to mean “an example of…” and, unless otherwise stated, does not imply an ideal or preferred embodiment.

[0050] In next-generation systems such as 5G New Radio (5G–NR), in order to increase bandwidth and throughput to the mobile station (UE), it may be necessary to support the reception of multiple PDCCH / PDSCH on the UE simultaneously, where possible.

[0051] In current LTE systems, Cooperative Multipoint (CoMP) transmission (e.g., Inter-cell Interference Cancellation (ICIC), Dynamic Point Selection (DPS), Dynamic Point Blanking (DPB), or Non-coherent Joint Transmission (NCJT)) can be used to mitigate co-channel interference between different Transport Points (TRPs). Using these methods, joint data transmission can be performed from multiple TRPs. However, current systems only allow mobile stations to receive a single PDCCH from the host transmission unit, while data on the PDSCH can be jointly transmitted.

[0052] This document provides examples of varying levels of detail to illustrate various aspects of the currently disclosed technology.

[0053] For example, when supporting a mobile station (UE) to receive multiple PDCCHs and PDSCHs from multiple TRPs or multiple antenna panels located on a single TRP, it is useful to coordinate the resource allocation (e.g., layer number, RS resources) of each PDCCH / PDSCH associated with various TRPs. Simultaneously, it is useful to find appropriate resource allocations based on reported UE capabilities to support substantially simultaneous reception of PDCCHs and PDSCHs at the mobile station (UE) while maintaining backward compatibility. Relatedly, it is useful to have a scheme in which the mobile station (UE) can identify and correctly demodulate and decode multiple PDCCHs, enabling the UE to support substantially simultaneous reception of PDCCHs and PDSCHs as well as substantially simultaneous transmission of PUCCHs and PUSCHs.

[0054] In yet another example, when a mobile station (UE) is supported in transmitting multiple PUCCHs and PUSCHs from multiple antenna panels located at the UE based on received PDCCHs, it is useful to coordinate the resource allocation (e.g., layer number, RS resources) associated with each PUCCH / PUSCH and the various downlink control information (DCIs). Simultaneously, it is also useful to find appropriate resource allocations based on reported UE capabilities to support the near-simultaneous transmission of PUCCHs and PUSCHs at the mobile station (UE) while maintaining backward compatibility.

[0055] In yet another example, when a mobile station (UE) is supported receiving multiple PDCCHs from multiple TRPs or multiple antenna panels located on a single TRP, it is useful to coordinate the settings (e.g., RS settings, reporting settings) of each PDCCH associated with various TRPs. Simultaneously, it is useful to find appropriate setting assignments based on the reporting capabilities of the UE to support the measurement of channel state information at the mobile station (UE) while maintaining backward compatibility. Relatedly, it is useful to have a scheme in which the mobile station (UE) can identify and correctly demodulate and decode multiple PDCCHs, enabling the UE to support simultaneous PDCCH reception and channel state information calculation.

[0056] Therefore, by utilizing the disclosed technologies, next-generation systems (such as 5G New Radio (5G NR)) can increase bandwidth and mobile station (UE) throughput where possible by supporting the simultaneous reception of multiple PDCCH / PDSCH.

Certain features described herein in the context of individual embodiments may also be implemented in combination in a single embodiment. Conversely, features described in the context of a single embodiment may also be implemented individually or in any suitable combination in multiple embodiments.

However, for backward compatibility purposes, it receives a single PDCCH 112 from the host transmission unit assigned to transmission point 104, but still receives PDSCH 114 jointly from both transmission points (TRPs) 104 and 106 via the CoMP technology described above. Figure 1B-1 A mobile station (UE) 102 in a wireless network is shown, which communicates with a transmission point 104 using the disclosed technology. The transmission point has an antenna array 140 consisting of two separate antenna groups (panels). However, for backward compatibility purposes, a single PDCCH 112 is received from the host transmission unit assigned to the antenna group (panel) 144 of the transmission point 104, but PDSCH 114 is still received jointly from the two antenna groups (panels) 142 and 144 of the transmission point 104.

[0062] Figure 13BA mobile station (UE) 102 in a wireless network is shown, which communicates with two transmission points (TRPs) 104 and 106 using the disclosed technology, but for backward compatibility purposes, receives a single PDCCH 112 from the host transmission unit assigned to transmission point 104, but sends PUCCH and PUSCH to both transmission points (TRPs) 104 and 106. Figure 13B-1 A mobile station (UE) 102 in a wireless network is shown, which communicates with a transmission point 104 using the disclosed technology. The transmission point has an antenna array 140 consisting of two separate antenna groups (panels) 142 and 144. However, for backward compatibility purposes, a single PDCCH 112 is received from the host transmission unit assigned to the antenna group (panel) 144 of the transmission point 104, but PUCCH and PUSCH are sent to the two antenna panels of the transmission point 104.

[0085] In some embodiments, resources for transmission can be configured independently within the respective transmission settings or based on semi-persistent coordination between the respective transmission units. Figure 4-1 An example of resource scheduling for each control information set is shown, where the downlink channel is divided into a control region 402 and a data region 404. In the control region, various control information sets 410, 412, ..., 416 are transmitted. The data region is further subdivided into sub-regions indexed from 1 to J.

As shown, data sub-regions can span multiple resource elements in the time-frequency space and do not necessarily have to be contiguous in time or frequency. In some embodiments, the data sub-region mapping can be incorporated into a transmission setup or control information set to indicate which of the possible J data sub-regions has been allocated to data already scheduled for the corresponding control information set (e.g., data 1 scheduled for CS 1(410)). This can be implemented using various data structures, including but not limited to bit vector maps, linked lists, hash functions, variable-length fields, variable field numbers, etc. In some embodiments, the allocation of data sub-regions from various transmission units can be accomplished using predefined rules known a priori to both the transmission unit and the mobile station (UE).

As shown, data sub-regions can span multiple resource elements in the time-frequency space and do not necessarily need to be contiguous in time or frequency. In some embodiments, the data sub-region mapping can be incorporated into a transmission setup or control information set to indicate which of the possible J data sub-regions has been allocated to data already scheduled for the corresponding control information set (e.g., data 1 scheduled for CS 1 (1602)). This can be implemented using various data structures, including but not limited to bit vector graphs, linked lists, hash functions, variable-length fields, variable field numbers, etc. In some embodiments, the allocation of data sub-regions from various transmission units can be accomplished through predefined rules known a priori to both the transmission units and the mobile station (UE).

Figure 5 M transmission units 506 associated with M and N508 control information sets are shown.

[0088] In some embodiments, to distinguish control information sets from different transmission units, a transmission indicator field is part of the control information set, which is blindly demodulated and decoded by the mobile station. In some embodiments, the transmission indicator field is interpreted as an unsigned integer whose value indicates the relevant transmission unit indexed from 1 to N. In some embodiments, N represents the maximum number of control information sets supported by the UE in a single scheduling time, even if not all control information sets are transmitted. In other embodiments, N represents the total number of control information sets transmitted to the UE in a single scheduling time. In some embodiments, the value of N can be sent to the UE via higher-layer signaling. The bit length of the transmission unit indicator field can be calculated as ceiling[log2(N)], where N is as described above. In some embodiments, the time-frequency spaces allocated to these control information sets are non-overlapping.

Figure 6The control region is further subdivided into control sub-regions 702, 704, ..., 706 with indices 1 to N, where N represents the total number of control information sets for the mobile station (UE) within a single scheduling time. As shown, each control sub-region is assigned to transmit control information sets 712, 714, ..., 716 scheduled by the corresponding transmission unit. In some embodiments, the starting position of the downlink channel resources belonging to each control sub-region can be determined, at least in part, based on the total number of resources in the control region and the transmission unit index 730, through a joint function. As shown, the control sub-regions can span multiple resource elements in the time-frequency space and do not necessarily need to be contiguous in time or frequency.

In some embodiments, the mapping of control information sets can be determined by prior rules known to the mobile station (UE) (e.g., ascending or descending order). In other embodiments, the mapping of control information sets can be configured by higher-layer signaling to the mobile station (UE).

In some embodiments, before expanding the control information set, it can be done using the methods described above and Figure 9 Similar processing as shown, further scrambling of the CRC is performed separately. In other embodiments, the scrambling sequence for scrambling the CRC can be determined, at least in part, based on the Transmission Unit Index or UE identifier (e.g., Radio Network Temporary Identifier (RNTI), or a combination of Transmission Unit Index and UE identifier), through a joint function. In other embodiments, CRC parameters can be transmitted to the mobile station (UE) via higher-layer signaling, including but not limited to its length, generator polynomial, initial state, bit order, byte order, byte sequence, etc. In some embodiments, the time-frequency spaces allocated for these control information sets are non-overlapping.

[0098] In another embodiment, the Overhead Channel State Information Reference Signal (CSI-RS) and DMRS resources are grouped together in a resource set relating to one or more large-scale channel characteristics. In some embodiments, when the DMRS is transmitted from the same TRP as the SS, the SS can be used as a reference for the DMRS. In some embodiments, when the DMRS is transmitted from the same TRP as the CSI-RS, the CSI-RS can be used as a reference for the DMRS. In other embodiments, when the DMRS is transmitted from the same TRP and has a similar transmit (Tx) beam to the SS, the SS can be used as a reference for the DMRS. In other embodiments, when the DMRS is transmitted from the same TRP and has a similar transmit (Tx) beam to the CSI-RS, the CSI-RS can be used as a reference for the DMRS.
