  • Patent number: 11147065
    Abstract: A wireless device may identify a set of resources reserved for feedback information (e.g., resource elements (REs) reserved for feedback such as acknowledgement (ACK) or negative ACK (NACK) information) within a transmission time interval (TTI). Feedback information may be mapped to the reserved set of resources (e.g., reserved REs). The wireless device may determine a set of unused reserved resources (e.g., a set of unused reserved REs) based on the number of feedback bits. The wireless device may then map other bits (e.g., zeros, known bits, pattern or sequence of bits, random bits, etc.) to the set of unused reserved REs, or boost transmission power of bits mapped around the unused reserved REs. In some cases, the number of reserved REs may be determined based on the number of feedback bits (e.g., the size of the ACK/NACK payload). The wireless device may then transmit the information to a base station.

  • Patent number: 11128521
    Abstract: Upon detection of a failure of a communication link between a remote management system and a communication node, a bypass link is established. The remote management system evaluates whether additional communication nodes can act as a bypass for management communications between the remote management system and the communication node whose management communication link has failed. The remote management system instructs a selected bypass communication node to establish the bypass management communication link between the bypass node and the disconnected node whose management communication link has failed. Depending on the relationship between nodes, management communications sent using the bypass link may be secured. The bypass link in some implementations may include multiple bypass communication nodes linked together to provide a chain of bypass management communication links between the remote management system and the disconnected communication node.

  • Patent number: 11064457
    Abstract: According to one aspect of the present disclosure, a method of paging policy differentiation in a 5G telecommunications network is provided. A User Plane Function (UPF) receives downlink data for a target User Equipment (UE), and provides a data notification to a Session Management Function (SMF), the data notification comprising a Quality of Service (QoS) indicator, which the SMF uses to determine QoS Information (QoSI) that is sent to an Access Management Function (AMF). The AMF determines whether a paging policy selection should be performed by the AMF or by a Radio Access Node (RAN) that serves the target UE: if by the AMF, the AMF selects a paging policy based on the QoSI and sends a paging message to the RAN, which pages the UE; if by the RAN, the AMF provides paging policy information to the RAN, which selects a paging policy and pages the UE accordingly.

  • Patent number: 11051288
    Abstract: A small cell device may communicate with a user device (e.g., a smartphone, a tablet computer, etc.) via a range extender device that extends the effective range of the small cell device to the user device. The small cell device, the range extender device, and the user device may communicate with one another using channels of a licensed spectrum (e.g., traditional LTE channels). The range extender device may determine channel conditions corresponding to an unlicensed spectrum (e.g., 5 Gigahertz (GHz) Spectrum) and communicate the channel conditions to the small cell device. Based on the channel conditions, the small cell device and the range extender device may select downlink-only channels of the unlicensed spectrum and cause the downlink capabilities of the channels of the unlicensed spectrum to be augmented by the downlink capabilities of the downlink-only channels of the unlicensed spectrum.

  • Patent number: 11051312
    Abstract: Disclosed is a mechanism to help control which of multiple carriers a base station will serve a UE on—perhaps which carrier should be the UE's primary component carrier for carrier-aggregation service. The disclosed mechanism can apply in a scenario where a base station is configured to provide service on multiple carriers including at least a first carrier and a second carrier, and when the base station is serving one or more relays respectively on each carrier. In that scenario, the selection of a carrier on which the base station should serve a UE could be made based at least on a consideration of how many UEs are served in total by the one or more relays that the base station serves respectively on each carrier, such as by selecting the carrier having the fewest such relay-served UEs.

  • Patent number: 11050891
    Abstract: A data processing system includes a unit which executes predetermined data processing by linking first and second apparatuses, a communication control unit which establishes and maintains a communication connection between the apparatuses even if the connection is not in a predetermined operation state capable of executing data processing, a pairing unit which causes the apparatuses to transition to a pairing state, and a control unit which, if the apparatuses' transition to the pairing state is not in a predetermined operation state, causes transition to the operation state by transmitting predetermined signals between the apparatuses via the communication control unit. The execution unit causes the apparatuses to transition to a pairing state, and then executes data processing by linking them. The communication control unit judges whether to establish a communication connection between the apparatuses by referencing pairing states between them, and of a combination with another first or second apparatus.

  • Patent number: 11032739
    Abstract: A header compression indicator may be used to enable header compression between a device and a gateway and between end devices in a network of constrained devices. The header compression indicator may be used to signal that header compression is in use, along with which context is to be used, and parameters thereof. The header compression indicator may also be used to trigger creation, update, retrieval, or deletion of a header compression context dynamically. A header context data format may be used to convey the encoding of header option information and corresponding data used in the management of the header compression contexts. Header compression contexts may be created, modified, queried, or deleted dynamically via existing messaging frameworks and operations, e.g., by appending a header compression indicator to existing standard messages.

  • Patent number: 11019638
    Abstract: The present invention relates to a method in a cellular communication system, for avoiding errors in a HARQ process, wherein an NDI flag is used both for indicating either semi-persistent scheduling, SPS activation or SPS retransmissions, and also for indicating, by toggling of the flag, a new transmission in dynamic scheduling mode. The method comprises the steps of receiving, in a scheduling message, an indication that dynamically scheduled transmission will take place; if a semi persistent resource has occurred for the same HARQ process since a previously received indication for dynamically scheduled transmission, then considering the NDI flag to be toggled regardless of the value of the NDI flag. Thus, if the condition is fulfilled, a UE will always regard the NDI flag as indicating or requesting a new data transmission.
