  • Patent number: 11510230
    Abstract: A method of indicating uplink feedback information includes: dividing time/frequency resources into at least one time/frequency resource set for uplink control information; notifying user equipment (UE) a division rule and/or result with respect to the time/frequency resource set with respect to the time/frequency resource; counting, based on the set to which time/frequency resources for transmitting uplink feedback information corresponding to downlink data for the UE belong, pieces of the uplink feedback information in a preset manner; and transmitting current count values to the UE. As such, it can be ensured that the number of pieces of uplink feedback information to be transmitted from the UE by multiplexing time/frequency resources for transmitting uplink data is the same as the number of pieces of downlink data transmitted from a base station and corresponds to the uplink feedback information, thereby ensuring good communication between the UE and the base station.

  • Patent number: 11483095
    Abstract: Hybrid automatic repeat request (HARQ) configurability on new radio (NR) unlicensed (NR-U) operations is disclosed. Time varying code block group (CBG) granularity may be defined by signaling a set of available CBG granularities to a user equipment (UE) for HARQ feedback. The UE monitors for control signaling that may be used to select the CBG granularity for the current slot. The UE may then perform HARQ feedback according to a format corresponding to the selected CBG granularity. Additional aspects disclose updating a contention window size (CWS) in NR-U operations considering the varying CBG granularity. A base station may compute an effective HARQ feedback value that accounts for the varied CBG granularity corresponding to transmissions at a configurable reference slot of set of slots. The base station will update the CWS depending on the relationship of the failure rate of the effective HARQ feedback and a transmission failure rate threshold.

  • Patent number: 11323851
    Abstract: Certain aspects of the present disclosure relate to methods and apparatus for multicasting traffic using multi-connectivity. A wireless network can send a downlink (DL) packet, which follows one path from a core network entity to a user equipment (UE) under current standards, to multiple base stations (BSs) and from each of the base stations to a UE. The UE receives the DL packet from whichever BS first delivers the DL packet, and then the UE sends a report reporting receipt of the DL packet back to all of the BSs. BSs that receive a report indicating the UE received the packet can drop the packet, even if they have not yet successfully delivered the packet. The same procedure can be used for an UL packet, which can be sent from a UE to multiple BSs, and from the BSs to a core network entity.

In a case where a retransmission control method is employed in consideration of adaptive MCS control in which the encoding rate can be changed, the scheduling section sets the MCS in accordance with CQI notified from the communication counterpart apparatus. When transmission data is encoded, the RV parameter bit-number setting section sets the number of bits used for signaling the RV parameter to decrease as the encoding rate of the first transmission is decreased and sets the RV parameter based on the number of bits. For example, in a case where the encoding rate R is R>2/3, two bits are set. In a case where the encoding rate 1/3<R?2/3, one bit is set. On the other hand, in a case where R?1/3, zero bits is set.

  • Patent number: 10972223
    Abstract: Timing considerations for autonomous uplink (AUL) downlink feedback information (AUL-DFI) is disclosed. With the flexible timeline for new radio (NR) operations, signaling of the processing timeline may be used for the served user equipments (UEs) to properly interpret the acknowledgement information in the AUL-DFI. The UE receives a signal identifying a minimum processing time of the serving base station to process AUL. Using the knowledge of the minimum processing time, the UE determines which of the outstanding AUL transmissions are accurately addressed in the AUL-DFI and which are still pending. Additional signaling to the UE may instruct the UE when to implement any changes to transmission parameters also signaled via the AUL-DFI. Slots prior to the indicated change time will be transmitted using the current parameters, while slots after the indicated time will use the updated parameters from the AUL-DFI.

  • Patent number: 10945188
    Abstract: Methods and systems are presented in this disclosure that enable mobile devices without access to an active network connection (e.g. cellular, satellite or Internet network) to communicate between each other by sending and receiving data packets (e.g. text, location, or image) through a mesh of connected devices. A mobile device receives a request to send a packet having an identifier of a recipient device. Based on the identifier, the mobile device determines whether the recipient device is in a list of mobile devices within a wireless range of the mobile device. Based on the determination, the mobile device includes the packet into an outgoing queue having packets for forwarding. The mobile device establishes one or more connections with one or more mobile devices in the list, and forwards one or more packets from the outgoing queue to the one or more mobile devices using the one or more connections.

  • Patent number: 10932265
    Abstract: Methods and apparatus for communicating and utilizing persistent allocation of resources are described herein. A base station may allocate persistent resources to a client station, and may associate the client station or persistent resource allocation with a particular shared NACK channel. The base station may monitor the NACK channel for a NACK indicating a map error. The base station may monitor the resource allocation to implicitly determine a map error. The base station may resend one or more persistent resource allocation information elements in response to the NACK or implicit error determination. A client station having a persistent resource allocation may monitor persistent resource allocation information elements in map messages and/or may indicate failure to receive a persistent resource allocation information element in a NACK message on a shared NACK channel.

  • Patent number: 10903943
    Abstract: Mobile devices, base stations, and/or relay stations may implement a method for an improved and reliable automatic repeat request feedback indication. A mobile device (UE) may establish communication within a wireless network, and indicate to the network that the UE is a special type device, e.g. a constrained device. The network (base station) may then not send an indication on a physical indicator channel to the UE when certain conditions are met, and instead, the mobile device may interpret control information received from the network on a physical control channel as a negative acknowledgment indication corresponding to an automatic repeat request from the network. The UE may then perform a retransmission according to the interpreted control information. A new control information format may be used to further define how the network and UE implement the automatic repeat request process, to reduce the total number of bits required in the control information.

  • Patent number: 10848222
    Abstract: Techniques for identifying events for updating beam configurations for wireless communications employing beamforming are described. The events may be based on a response message to an aperiodic reference signal (RS). For example, a device that receives an aperiodic RS may transmit a message to the device that transmitted the aperiodic RS to confirm that the aperiodic RS was received. Additionally or alternatively, a device that receives an aperiodic RS may set a timer after receiving the aperiodic RS (or transmission of the confirmation message), and may update its beam configuration upon expiration of the timer. If control information is received to schedule a second aperiodic RS prior to expiration of a timer for a first periodic RS, a device may update the timer. Updating the timer for aperiodic RS may be individual to different aperiodic RS transmissions, or may be common among aperiodic RS.
