Patent number: 11800541Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a shared physical downlink shared channel (PDSCH). The UE may receive a first communication via the shared PDSCH and a first bearer based at least in part on the configuration, the first communication being one of a unicast communication or a multicast/broadcast communication. The UE may receive a second communication via the shared PDSCH and the first bearer or a second bearer based at least in part on the configuration, the second communication being the other of the unicast communication or the multicast/broadcast communication. Numerous other aspects are provided.Type: GrantFiled: November 11, 2022Date of Patent: October 24, 2023Assignee: QUALCOMM IncorporatedInventors: Xipeng Zhu, Prasad Reddy Kadiri, Alberto Rico Alvarino, Gavin Bernard Horn, Umesh Phuyal, Miguel Griot, Xiaoxia Zhang

Publication number: 20230337234Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration for a group-common physical downlink shared channel (PDSCH), where the group-common PDSCH is repeated for a number of repetitions. Accordingly, the UE may determine this number of repetitions and then monitor for the group-common PDSCH based on the number of repetitions. In some implementations, the group-common PDSCH may include a semi-static repetition scheme, where the number of repetitions is indicated via a group aggregation factor. Additionally or alternatively, the group-common PDSCH may include a dynamic repetition scheme, where the number of repetitions is indicated via a group repetition number. Additionally, the techniques described herein may enable the configuration for the repeated group-common PDSCH to include gaps between each repetition of the group-common PDSCH and for the UE to transmit acknowledgment feedback for the repetitions of the group-common PDSCH.Type: ApplicationFiled: June 23, 2023Publication date: October 19, 2023Inventors: Le LIU, Alberto RICO ALVARINO, Peter GAAL, Kazuki TAKEDA, Jing SUN, Wanshi CHEN, Ayan SENGUPTA, Juan MONTOJO, Mostafa KHOSHNEVISAN, Prasad Reddy KADIRI

Patent number: 11792824Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently allocating resources for multicast feedback from one or more user equipment (UEs) and efficiently retransmitting information in transport blocks to the one or more UEs. If a UE fails to decode one or more transport blocks of a set of transport blocks from a base station, the UE may report feedback, such as a negative acknowledgment (NACK), to the base station. The base station may receive the feedback from the UE and potentially from other UEs that failed to decode one or more transport blocks of the set of transport blocks, and the base station may multicast one or more outer-coded transport blocks to the UEs. Each of the outer-coded transport blocks may include a different combination (for example, a linear combination) of transport blocks of the set of transport blocks.Type: GrantFiled: March 26, 2021Date of Patent: October 17, 2023Assignee: QUALCOMM IncorporatedInventors: Le Liu, Alberto Rico Alvarino, Peter Gaal, Kazuki Takeda, Ayan Sengupta, Wanshi Chen, Xiaoxia Zhang, Juan Montojo, Tao Luo, Prasad Reddy Kadiri

Patent number: 11792826Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARQ) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).Type: GrantFiled: April 27, 2021Date of Patent: October 17, 2023Assignee: QUALCOMM IncorporatedInventors: Kazuki Takeda, Alberto Rico Alvarino, Le Liu, Peter Gaal, Wanshi Chen, Ayan Sengupta, Prasad Reddy Kadiri, Tao Luo, Mostafa Khoshnevisan, Juan Montojo, Umesh Phuyal, Wooseok Nam

Patent number: 11711826Abstract: Methods, systems, and devices for on-demand multicast control channel (MCCH) messages are described. A user equipment (UE) may receive, from a base station, system information indicating an MCCH message configuration. Based on receiving the MCCH message configuration, the UE may transmit a request for an MCCH message. For example, the UE may transmit the request for the MCCH message by a random access preamble or a radio resource control (RRC) message. After transmitting the request, the UE may receive the MCCH message in accordance with the MCCH message configuration. That is, the base station may receive the request and transmit the MCCH message in response to the request. The MCCH message may indicate a multicast service radio bearer (MRB) configuration for receiving multicast traffic. Thus, the UE may receive multicast traffic from the base station in accordance with the MRB configuration.Type: GrantFiled: January 4, 2021Date of Patent: July 25, 2023Assignee: QUALCOMM IncorporatedInventors: Xipeng Zhu, Prasad Reddy Kadiri, Xiaoxia Zhang

Patent number: 11711825Abstract: Methods, systems, and devices for wireless communications are described. A set of uplink control channel resources that are configured for acknowledgment transmissions may be shared among user equipments (UEs) that are enabled to receive multicast communications. Each of the shared set of uplink control channel resources may be associated with set(s) of channel state information. UEs may measure a multicast channel to determine channel state information for the multicast channel. After failing to receive a multicast transmission, UEs may transmit an acknowledgment feedback message over one of the shared uplink control channel resources that is associated with the set of channel state information determined by the UE. A base station that receives the acknowledgment feedback message may transmit a multicast retransmission for the UEs using transmission parameters that are adapted for the set(s) of channel state information associated with the occupied uplink control channel resource.Type: GrantFiled: November 12, 2020Date of Patent: July 25, 2023Assignee: QUALCOMM IncorporatedInventors: Kazuki Takeda, Alberto Rico Alvarino, Ayan Sengupta, Jing Sun, Le Liu, Miguel Griot, Mostafa Khoshnevisan, Peter Gaal, Prasad Reddy Kadiri, Xiaoxia Zhang, Tao Luo, Umesh Phuyal, Wanshi Chen
