Abstract: An Acknowledgement-Negative Acknowledgement (ACK-NACK) feedback message transmitted from a receiving device to a source device indicates which code words within a transport block transmitted from the source device to the receiving device were received in error by the receiving device. The ACK-NACK message has a variable format based on the number of code words in the transport block and the number of code words received in error.

Abstract: A spatial multiplexing scheduler in, for example, an eNB or other base station, determines rank n precoders for UEs. Each UE reports the preferred precoder from this set of rank n precoders. The preferred precoder results in imbalance in performance over m layers compared to the rest of (n−m) layers. The UEs also report channel quality to the eNB, from which the eNB determines which layer(s) is better for the UE. For example, when n=2 and m=1, the eNB may then select two UEs such that, for the same precoder used by the UEs, the first UE has much higher layer 1 performance than layer 2, and the second UE has much higher layer 2 performance than layer 1. These two UEs may then share the same frequency-time domain resources, with the first UE information sent/received on layer 1, while the second UE information is sent/received on layer 2.

Abstract: A communication device, such as a smart phone, receives a power specification message from a network controller. The power specification message specifies an output power applicable for a particular communication subframe or symbol within the subframe. In response to the power specification message, the communication device determines a new shaping table and replaces an existing shaping table with the new shaping table. The communication device uses the shaping table to generate an envelope signal for an envelope tracking power supply, and the new shaping table is adapted to provide power saving operation at the specified output power.
