  • Patent number: 11121821
    Abstract: In order to address problems arising due to conflicting transmissions of different services, each transport block transmitted to a receiver includes at least two code blocks and the decision by the receiver to flush and replace parts of the soft buffer and/or to add the soft bits to only some of the code blocks of a transport block is based on a combination of the multi-bit feedback transmitted by the receiver and a multi-bit indication in the DCI (Downlink Control Information) transmitted by the transmitter.

  • Publication number: 20210281380
    Abstract: A system and method to instruct a user equipment (UE) how Uplink Control Information (UCI) on a Physical Uplink Shared Channel (PUSCH) should be transmitted with carrier aggregation. A semi-static signaling of a UCI mapping bit (via a Radio Resource Control (RRC) parameter) is used by a base station such as an eNodeB to require the UE to transmit UCI using one of two pre-determined UCI transmission modes. The bit can be decided by the base station, considering, for example, the available bandwidth or quality of different Uplink Component Carriers (UL CCs) associated with the UE. This network-based solution allows the network to either configure a general rule of UCI transmission by the UE or to enforce the UCI transmission on the Uplink Primary cell (UL Pcell). Because of the rules governing abstracts, this abstract should not be used to construe the claims.

  • Publication number: 20210243798
    Abstract: Embodiments herein relate to a method performed by a network node 110 of a wireless communication network 100 for communicating at an unlicensed frequency spectrum with a wireless device 121 having a device identity. The network node 110 sends an access grant to the wireless device according to the device identity, granting the wireless device access to an uplink communication channel of the unlicensed frequency spectrum. The network node also receives data from the wireless device 121, on the granted uplink communication channel, the data comprising information on the identity of the wireless device 121, thus enabling the network node 110 to detect whether the wireless device that was granted access on the uplink communication channel is the same wireless device as the wireless device from which the data comprising the information on the uplink communication channel was subsequently received. Embodiments of the network node 110 are also described.

  • Publication number: 20210204273
    Abstract: PUCCH resource determination for HARQ-ACK transmission in response to ePDCCH-scheduled PDSCH or ePDCCH-indicated SPS release in a TDD radio communication system. Downlink control information (DCI) is received in a downlink subframe via an Enhanced Physical Downlink Control Channel (ePDCCH). A resource index for a Physical Uplink Control Channel (PUCCH) resource is determined, based on the lowest enhanced Control Channel Element (eCCE) index of the received DCI, a device-specific offset value, and an index i that identifies the downlink subframe in a pre-determined set of one or more downlink subframes associated with an uplink subframe. The PUCCH resource is determined according to a formula that results in a sequential allocation of PUCCH resources in the uplink subframe with respect to the downlink subframes associated with the uplink subframe, for each of a plurality of sets of ePDCCH resources. HARQ feedback is transmitted in the uplink subframe, in the indexed PUCCH resource.

  • Publication number: 20210194643
    Abstract: A user equipment is configured with at least two collections of uplink resources to be used for transmitting control information to a communication network. The UE receives an assignment of radio resources to be used for receiving a downlink transmission from a base station of the communication network. The UE receives an acknowledgement resource indication, ARI, indicating one of the configured collections of uplink resources to be used for transmitting control information associated with the DL transmission. Further, the UE transmits the control information to the base station on at least a subset of the indicated collection of UL resources. In example embodiments, the indicated collection of uplink resources comprises a plurality of selectable uplink resource sets. The control information is transmitted on one of the uplink resource sets which corresponds to an operational state of the communication network.
