摘要： One way to increase robustness against beam pair link failure is by transmitting downlink (DL) control signaling (e.g., PDCCH) in more than one beam. That is, one way to mitigate BPLF is for the UE to receive DL control signaling over both a first BPL (e.g., active BPL) and a second BPL (e.g., monitored BPL) but with larger duty cycle for the second BPL compared to the first BPL. For example, the control signaling can be scheduled every slot on the first BPL and scheduled every Nth slot on the second BPL. In this way, in case the first BPL is blocked and the UE cannot decode the control signaling on the first BPL, the UE can receive control signaling transmitted on the second BPL.

摘要： A radio network controller, RNC, 614, and a method therein, for enhancing reception quality of transmissions on an uplink control channel from a user equipment, UE, 613 to a serving base station, BS, 610. The RNC, the UE and the serving BS are comprised in a communication system 600. The method comprises, when conditions for boosting the uplink control channel are fulfilled, determining a boosting factor based on a ratio of path gains of a channel from the UE to the serving BS and of a channel from the UE to a non-serving BS 611, respectively, which non-serving BS is comprised in the communications system. The method further comprises transmitting the determined boosting factor to the UE, whereby the reception quality of transmission on the uplink control channel from the UE to the serving BS is enhanced by the UE boosting the control channel by means of the boosting factor.

摘要： Teachings herein offer reduced-complexity coordinated multipoint (CoMP) reception of an uplink signal transmitted by a mobile terminal. The teachings obtain, for each sector antenna in a set of sector antennas deployed in a CoMP cell, a signal strength measurement of one or more downlink signals received by the mobile terminal from a sector associated with that sector antenna. The teachings compare the signal strength measurements and then select from the set, based on that comparison, a subset of sector antennas for CoMP reception of the uplink signal. By using a subset of sector antennas for CoMP reception, instead of all sector antennas in the set, the teachings reduce the computational complexity of CoMP reception. Moreover, the teachings in some embodiments minimize any performance degradation possibly resulting from performing CoMP reception with a reduced number of antennas, by selecting the subset to include sector antennas having the strongest signal strength measurements.
