Systems and methods are provided for redundant antenna systems and methods of managing the power allocated thereto. A redundant antenna system comprises a first antenna array and a second antenna array, wherein each of the first and second antenna arrays are oriented to transmit downlink signals to different geographic areas. A first set of antenna elements of the first antenna array and a second set of antenna elements of the second antenna array are powered by a common power supply. In a normal operating mode, the power supply only powers the first set of antenna elements and in aspects of a redundant operating mode used to serve a degraded geographic service area, the power supply powers both the first set of antenna elements and the second set of antenna elements.

A wireless device receives a report mask indicating a transmission of a layer 1 reference signal received power (L1-RSRP) report limited to a time period when a discontinuous reception (DRX) timer is running. The L1-RSRP report is transmitted, at a first time, in response to the DRX timer running at a predefined time period before the first time. The L1-RSRP report may include, for example, an L1-RSRP value and a reference signal index associated with the L1-RSRP value. Ata second time, a configured L1-RSRP report transmission is skipped in response to: the DRX timer not running at the predefined time period before the second time and the report mask.

A user matching and power distribution methods for a MIMO-NOMA downlink communication system is provided. The user matching method includes: dividing all users into a strong user group and a weak user group according to a channel gain sorting result; and sequentially selecting a user in the strong user group, calculating a correlation coefficient between the user and each user in the weak user group, selecting a weak user with the highest correlation coefficient as a weak user in a cluster where the strong user is located, and excluding matched users from respective user groups, until the matching between all strong users and weak users are completed. The present invention enables weak users in a cluster to experience less inter-cluster interference in scenarios where the channel correlation between users is relatively low, thereby improving the total throughput of the communication system.
