    摘要: The present disclosure relates to component carrier (CC) selection in a wireless communication system. A user equipment (UE) that is in idle mode may receive a reference signal (RS) from an evolved Node B (eNB), obtain signal quality measurements with respect to the RS, and switch to a new CC based on the signal quality measurements. For a UE that is in connected mode, an eNB may obtain uplink channel condition information corresponding to uplink CCs, obtain downlink channel condition information corresponding to downlink CCs, and select a CC pair for the UE to use based on the uplink channel condition information and the downlink channel condition information.

    摘要: A method for assigning and coordinating uplink reference signals for cooperative communication is disclosed. Data about an assigned uplink reference signal sequence used by a wireless communication device is received at a non-serving base station. An uplink reference signal estimate is determined based on the data. The uplink reference signal estimate is used to coherently demodulate a signal received from the wireless communication device or is used to estimate an uplink channel between the non-serving base station and the wireless communication device.

    摘要: A wireless communication device may autonomously transition from a multiple antenna port mode to a single antenna port mode. The wireless communication device may implicitly notify a base station about the autonomous transition from the multiple antenna port mode to the single antenna port mode. The base station may reallocate resources that were previously allocated to the wireless communication device but that are no longer being used by the wireless communication device. In some cases, the base station may configure the wireless communication device's antenna port mode via radio resource control signaling.

    摘要: A base station configured for coordinating uplink resource allocation is described. The base station includes a processor and instructions stored in memory. The base station generates uplink resource allocation information for one or more wireless communication devices. The uplink resource allocation information is sent to one or more base stations. The base station allocates uplink resources based on the uplink resource allocation information. The base station sends an assignment to one or more wireless communication devices based on the uplink resource allocation information.
