  • Patent number: 11632700
    Abstract: In order to perform a RACH-less handover from a source base station to a target base station, a UE device generates a request that the target base station is to send a Media Access Control (MAC) message to the UE device. The request can be sent with a Radio Resource Control (RRC) Connection Reconfiguration Complete message. Alternatively, an RRC message sent from a UE device functions as an implicit request that the target base station is to send a MAC message to the UE device. The request can also be configured to specify a particular MAC Control Element that the target base station should send. The target base station transmits the requested MAC message, along with TA information, if required. The UE device determines when the handover has been completed, based at least partially on when the requested MAC message is received from the target base station.

  • Patent number: 11627618
    Abstract: A system uses signals received from actual user equipment (UE) to build in real time a reception pattern for base stations in a cellular communication system. Each UE is assigned a unique tone to broadcast so that a controller can analyze radio coverage by analyzing which base stations received signals from each UE in a coverage area. Cellular base stations necessarily have overlapping coverage and are assigned unique channel access values to avoid repeating values from overlapping cell sites. As overlaps change in real time, in response to live events, traffic jams, site outages, and new sites, signals received from UEs in the coverage area provide a real time view of system coverage. This allows better allocation of channel access values than prior art historical performance indicators using base station and controller call errors.

  • Patent number: 11575780
    Abstract: An indicator (e.g., “5G+” or “5G”) displayed on a mobile device is based on whether the mobile device is connected in or (if idle) has the potential of connecting in a high channel bandwidth frequency band (e.g., n77 or mmWave). An accurate indication is displayed when the mobile device is connected, or when idle and the aggregated bandwidth is not directly known, such as when anchored to a lower bandwidth cell. When in idle mode, the mobile device can maintain cell identifiers (“fingerprints”) and determine a location estimated to be within a high bandwidth cell, to thereby determine potential high bandwidth operation (e.g., and display 5G+) when connected. When in the idle mode, the mobile device can evaluate neighbor cells including if within a high channel bandwidth cell's coverage to decide whether to select “5G+” or “5G” for display to indicate the potential high bandwidth operation (or not) when connected.

  • Patent number: 11233620
    Abstract: Systems, methods, and devices can be utilized to schedule at least one Hybrid Automatic Repeat Request (HARQ) transmission and at least one HARQ feedback message in the same Physical Resource Block (PRB). A HARQ transmission can be scheduled in a mini-slot of the PRB. Accordingly, latencies associated with transmitting and receiving the PRB can be reduced, while the high reliability of HARQ can be retained. Implementations can be applied to 5G technologies such as Ultra Reliable Low Latency Communications (URLLCs) and enhanced Mobile BroadBand (eMBB), as well as other low-latency communications. A method can include determining a location of a device; selecting, based at least in part on the location of the device, a mini-slot size; scheduling, in one or more mini-slots having the mini-slot size in a PRB, a HARQ transmission; and transmitting, to the device, the HARQ transmission in the one or more mini-slots of the PRB.

  • Patent number: 11218940
    Abstract: The present disclosure relates to a cell reselection method and device, and a storage medium in the field of communication technology. The cell reselection method includes: a terminal acquires cell reselection parameters carried in a system message of a target cell. Since the cell reselection parameters of the target cell are set according to terminal speeds, the terminal takes its own speed into account when determining the signal quality of the target cell according to the cell reselection parameters. That is, the terminal selects one cell from a serving cell and at least one neighbor cell for residence after considering its own speed.

  • Patent number: 11219080
    Abstract: User equipment (UE) can select a connection type for a retry of a failed call based on system information blocks (SIBs) received from a serving base station of a first radio access layer of a telecommunication network. When the UE experiences a call setup failure of a call attempted through the serving base station of the first radio access layer, the UE can determine whether neighbor information within the SIBs includes information about a neighboring base station of a second radio access layer. If it does, the UE can select a retry connection type as a connection to the neighboring base station of the second radio access layer. If it does not, the UE can select the retry connection type as a connection to an alternate network. The UE can then retry the call through the selected retry connection type.

  • Patent number: 11206682
    Abstract: Group transmission of data from a group of User Equipment devices to a network node of a cellular communication system where communication between devices is effected by device-to-device technology can provide significant improvements in uplink coverage and user bit rate. However, the benefits of group transmission means that not all devices of a group have sufficient network coverage to reliably receive a grant signal scheduling uplink resources from a network node. Methods, devices and a network node are proposed that enable the dynamic selection of either a direct grant mode, in which each device receives the uplink grant directly from the network, or a relayed grant mode, in which a device acting as group coordinator relays the grant to all members of the group, to ensure optimal performance for group transmissions. The selection is dependent on at least one determined condition relating to the group of devices and/or the group transmission.

  • Patent number: 11184856
    Abstract: This disclosure relates to a method for reducing power consumption of a first device for use in a wireless communication system. The first device receives a signal within a first reference sub-frame of a radio channel. The device determines whether to use the signal for obtaining channel state information to be reported to a second device within a reporting sub-frame, or whether to receive and use a second signal within a second reference sub-frame of the radio channel for obtaining channel state information to be reported to the second device within said predetermined later sub-frame. Based on this determination, the first device reports channel state information obtained based on the signal received within said first reference sub-frame or said second signal within said second reference sub-frame to the second device within said reporting sub-frame.

  • Patent number: 11178685
    Abstract: A user equipment (UE) may transmit a UE-generated uplink message to a base station to request resources for an uplink transmission. The UE may be configured to send the message (e.g., a scheduling request (SR)) using different transmission modes. For example, the UE may transmit the SR using a scheduled mode where the UE conveys the SR along with another uplink message (e.g., a control message). In some examples, the UE may transmit the SR using an autonomous mode where the UE transmits the SR in resources reserved for SR transmissions. The UE may determine which transmission mode to use based on certain characteristics of the SR or the data associated with the SR.
