  • Patent number: 10524282
    Abstract: Methods, systems, and devices are described for transmissions and retransmissions of scheduling assignment (SA) information, and for content of SA transmissions. SAs may be transmitted during an initial communications period, followed by data transmissions for a certain time period. A device may monitor for transmissions during the SA period and then monitor for data transmissions during periods indicated in a received SA. SAs may be retransmitted according to a retransmission pattern that may provide time or frequency diversity patterns in order to enhance reception of SAs at a receiving device. Retransmission patterns may be determined based on a resource from an SA resource pool that is used for an initial transmission of the SA.

  • Patent number: 10524283
    Abstract: A wireless telecommunications system that supports a virtual carrier mode operation in which downlink communications are made by a base station while a terminal device receives at least some communications from the base station within a restricted subset of transmission resources. When there is to be a change in system information, the base station transmits to the terminal device an indication that updated system information is to be broadcast by the base station to plural terminal devices and the terminal device seeks to acquire the updated system information using the restricted subset of transmission resources. The base station further conveys to the terminal device an allocation of uplink transmission resources for acknowledgement signalling for the updated system information and the terminal device responds by using the allocated uplink transmission resources to convey to the base station an indication whether or not the terminal device has acquired the updated system information.

  • Patent number: 10517122
    Abstract: A radio network node (110) manages (A010) establishment of a current radio session between a user equipment (120) and the radio network node (110), wherein the current radio session is associated with a current set of characteristics relating to the radio network node (110) and/or the user equipment (120). During establishment of the current radio session, a core network node (130) retrieves (A080), based on the current set of characteristics, an indication about the MCS offset from a memory (141, 142) accessible by the core network node (130). Then, the core network node (130) sends (A090), to the radio network node (110), the indication about the MCS offset. The indication is derived from a previous radio session, wherein the previous radio session is associated with a previous set of the characteristics, wherein the previous set of the characteristics matches the current set of the characteristics.

  • Patent number: 10511989
    Abstract: A method of uplink shaping and extending UE in RRC Idle Mode is proposed. The UE processes a data packet to be sent to the network. The data packet is associated with a traffic type. If the data packet belongs to a normal traffic type, then the UE enters RRC Connected mode and thereby transmitting the data packet to the network. If the data packet belongs to a background traffic type, then the UE buffers the data packet and the UE is prohibited from entering RRC Connected mode until a triggering condition is satisfied for uplink transmission. The proposed mechanism achieves power saving by reducing the activity of uplink transmission. In addition, the proposed mechanism also reduces signaling overhead to enhance network efficiency.

  • Patent number: 10499417
    Abstract: The invention relates to a control channel signal for use in a mobile communication system providing at least two different scheduling modes. Further the invention relates to a scheduling unit for generating the control channel signal and a base station comprising the scheduling unit. The invention also relates to the operation of a mobile station and a base station for implementing a scheduling mode using the control channel signal. In order to facilitate the use of different scheduling schemes for user data transmission while avoiding an additional flag for indicating the scheduling mode in the control signaling, the invention proposes the use of code points in existing control channel signal fields. Further, the invention proposes a specific scheduling mode for use in combination with the proposed control channel signal. According to this scheduling mode control channel information is only provided for retransmissions, while initial transmissions are decoded using blind detection.

  • Patent number: 10470128
    Abstract: In wireless communications, a station associated with a first wireless network may perform early detection of a high-efficiency (HE) frame for spatial reuse (SR). The station may determine a received power of a legacy preamble of the HE frame when the frame is associated with a second wireless network. The station may reduce the received power by a predetermined value. The station may initiate an SR transmission, when the reduced power is less than an overlapping basic service set (OBSS) packet detection level. The station may obtain an SR parameter associated with a second station, where the SR parameter is based on a transmission power level and an interference level at the second station, and initiate an SR transmission, based on the SR parameter and the reduced power. Other methods, apparatus, and computer-readable media are also disclosed.

  • Patent number: 10454571
    Abstract: Dynamic determination of threshold power level for use in distinguishing between downlink and uplink periods in time-division duplexed (TDD) communications. For example, downlink and uplink periods may be distinguished in TDD communications in a distributed communications system (DCS), such as a distributed antenna system (DAS). Detecting a power level in a TDD communications signal less than the threshold power level is used to identify uplink periods in the TDD communications signal. In this manner, TDD communications circuits involved with transmitting TDD communications signals can synchronize their transmission circuitry to only transmit downlink TDD communications signals in downlink periods and receive uplink TDD communications signals in uplink periods.
