    摘要: In accordance with some embodiments, in a time division duplex system, the transmission direction may be changed dynamically, for example in response to instantaneous traffic conditions. Particularly in some embodiments an eNodeB or base station may, in response to instantaneous traffic conditions, change the direction of transmission in certain subframes. In some embodiments this can be done in a way which is backwards compatible with prior generations of Long-Term Evolution (LTE) radio systems.

    摘要: Technology for synchronization of uplink transmission with multiple timing advances in a wireless communication environment is disclosed. Additional resource allocation messages for additional timing advances are addressed to a user equipment specific search space. A number of band decodes needed to find a resource allocation message used to access an additional timing advance can be reduced by padding the resource allocation message. A number of blind decodes used to find the resource allocation message can also be reduced by restricting the control channel candidates in which the resource avocation can be embedded in terms of the control channel element aggregation level, or levels, associated with acceptable control channel candidates.

    摘要: Devices and methods of reducing blind decoding attempts of user equipment (UE) suing carrier aggregation are generally described. The UE may determine at least one subframe in a modification period to monitor for a physical downlink control channel (PDCCH) formed in accordance with a Discontinuous Transmission Downlink Control Information (DTX DCI) format. The DTX DCI format may indicate whether the serving cell is in a DTX or non-DTX state. The UE may determine the DTX state of each serving cell from the DTX DCI format and monitor an enhanced PDCCH of each serving cell in the non-DTX state to provide a scheduling assignment for the UE, without monitoring each serving cell in the DTX state. The UE may receive higher layer signaling that indicates a repetition period and subframe offset for DTX DCI format transmissions or a bitmap of the DTX DCI format transmissions for subframes within each modification period.

    摘要: A Second Synchronous Signal (SSS) for a 3GPP LTE downlink signal is generated in such a way that a legacy User Equipment (UE) can determine whether the downlink signal comprises a legacy downlink signal or a New Carrier Type (NCT) downlink signal, which is unavailable to a legacy UE. One exemplary embodiment provides that a first binary sequence and a second binary sequence are generated in which the first and second binary sequences are part of the SSS for the downlink signal. The first binary sequence is multiplied by a first scrambling sequence, and the second binary sequence by a second scrambling sequence in which the first and second scrambling sequences are selected to indicate that the downlink signal is a new carrier type downlink signal. Other exemplary embodiments provide that an order of the first and second scrambling sequences indicates whether the downlink signal is a NCT downlink signal.
