Abstract: Multiple downlink (DL) and uplink (UL) carriers can enhance wireless communication between nodes and user equipment (UE). Among the carriers, it is beneficial to have some special, by configuration designated carriers to provide synchronization, system information, paging, data and control for multi-carrier enabled UEs. Thereby, overhead system information can be reduced. For instance, synchronization and paging for a certain cell are not provided on all carriers. A carrier can provide backward compatibility for single carrier UEs for access, synchronization, broadcast, and new control region within the data region of the legacy terminals. Coordination between nodes for selecting anchor carriers that mitigate interference and for transmit power control for non-anchor carriers provide further network performance advantages.

Abstract: Embodiments of the present disclosure provide an uplink power control method, a user equipment and a base station. The method comprises: receiving configuration information of a channel state information reference signal CSI-RS from the base station, wherein the configuration information of the CSI-RS comprises reference signal port information and reference signal power information; and measuring a path loss for uplink power control based on the configuration information of the CSI-RS. The embodiments of the present disclosure use the CSI-RS to measure the path loss, which differs from a common CRS in that the CSI-RS may aim at a specific base station. Therefore, path loss measurement may be performed in respect of a target base station of uplink transmission, enabling the path loss compensation to match the actual path loss, thus improving the performance of uplink power control.

Abstract: A user equipment (UE) operating in a communication system comprising a base station and one or more UEs. The UE may be configured to operate on or “camp” on two different networks with one radio. In this exemplary system, the radio may be normally connected to the first network (NW1) and may from time to time be “tuned away” from NW1 to a second network (NW2). The UE may inform NW1 that it has tuned away to another network, e.g., using start and end indicators. This information may prevent NW1 from wasting downlink capacity by unnecessarily allocating downlink resources to the UE during the tune-away. Alternatively, or in addition, this information may prevent NW1 from penalizing the UE, e.g., by reducing its future downlink allocations, since the UE does not respond to NW1 commands during the tune-away.
