  • Publication number: 20180227887
    Abstract: Signaling is received (or transmitted) to configure a UE with multiple transmit beams, each for receiving beam-specific DCI. A beam-specific current DCI is received at the UE (or transmitted from a network) on the transmit beam(s), including information about beam-specific previous DCIs transmitted to the UE on any of the multiple transmit beams within a predefined time window preceding a time unit in which the current DCI was received. Information about the beam-specific previous DCIs is used to determine that at least one of the multiple transmit beams has been blocked. Each of the multiple transmit beams that have been determined to be blocked is reported to (and received by) the network. In response to receiving from the UE a report indicating at least one multiple transmit beams has been blocked, the network reconfigures the UE with a different set of multiple transmit beams each for beam-specific DCI.

  • Patent number: 9473281
    Abstract: A method provides information to a UE specifying a UL-DL configuration to be applied to the UE. The information is indicative of: (a) a signaling time at which a UL-DL configuration signaling for a new UL-DL configuration is to take place, and (b) an application time at which the new UL-DL configuration is to be applied. This method complements UL-DL configuration signaling by providing more reliable reception of UL-DL configuration information. This indication is performed with smaller signaling overhead compared to conventional schemes and with reasonable complexity on both the UE side and an eNB side.

  • Patent number: 9143289
    Abstract: It is determined that there are X uplink control channel resources available for uplink signaling. Each of those X uplink control channel resources are sub-channelized into a plurality of sub-channels that each defines a unique time instant or point in time. For each of Y units of control information there is selected a unique combination of one of the sub-channels and a modulation (X and Y are each integers greater than one). The Y units of control information are sent on the X uplink control channel resources according to the respectively selected combinations. By example the uplink resources may be an ACK/NAK/DTX bit on a PUCCH. In one example the sub-channels are individual slots of a PUCCH. In another example the sub-channels are the reference-signal part and the data part of a single PUCCH slot.

  • Patent number: 9014694
    Abstract: A first user equipment UE operating in a first/strong transmission mode determines that a second UE is operating in a second/weak mode and is allocated a same radio resource as the first UE. The first UE determines a transport format for transmissions to the second UE and uses that to decode and cancel a transmission received on the radio resource which is directed to the second UE, mitigating interference with a further transmission directed to the first UE. Various examples are given of specific resource allocation signaling used to determine that the second UE is operating in the second mode and is allocated the same radio resource, such as implicitly by a specific downlink control indication format or an explicit indication in a resource allocation directed to the first UE. The first UE can determine the transport format of the second UE from network signaling.

  • Publication number: 20150092757
    Abstract: A downlink data transmission is performed in a downlink subframe. One or more resources are determined. The one or more resources are to be used for transmission or reception of error information for the received transmission in an uplink subframe based at least on an association set between one or more downlink or special subframes and an uplink subframe. The determined association set depends on a downlink reference configuration. The association set for each uplink subframe comprises a grouping of the downlink or special subframes into at least two groups. An association set is defined only for the subframes which are uplink subframes in a corresponding downlink reference configuration. The error information is transmitted or received using the determined one or more resources in the uplink subframe. Methods, apparatus, programs, and program products are disclosed.
