Abstract: Embodiments of user equipment (UE) and methods for codebook subsampling for enhanced 4TX codebooks in 3GPP LTE wireless networks are generally described herein. In some embodiments, a physical uplink control channel (PUCCH) is configured for transmission of channel state information (CSI) feedback including a rank indicator (RI) and a precoding matrix (W1). The rank indicator (RI) and a precoding matrix (W1) are jointly encoded and codebook subsampling is performed for the enhanced 4Tx codebook for at least one of: PUCCH report type 5 (RI/1st PMI) in PUCCH 1-1 submode 1; PUCCH report type 2c (CQI/1st PMI/2nd PMI) in PUCCH 1-1 submode 2; and PUCCH report type 1a (subband CQI/2nd PMI) in PUCCH 2-1.

Abstract: This disclosure describes systems, methods, and devices related to using enhanced high efficiency (HE) frames. A device may determine a high efficiency signal-B (HE-SIG-B) field for a high efficiency (HE) frame, the HE-SIG-B field comprising a common information field and a user information field. The device may determine a data portion of the HE frame, wherein the data portion includes one or more resource units (RUs) with a size equal to a number of tones. The device may determine a first resource allocation subfield and a second resource allocation subfield of the common information field based at least in part on the number of tones. The device may cause to send the HE frame.

Abstract: This disclosure describes systems, methods, and devices related to a flexible connectivity framework. A first device may send a trigger frame to a second device. The first device may then receive an uplink bandwidth resource request from the second device. The first device may detect a high efficiency-long training field (HE-LTF) in the uplink bandwidth resource request. The first device may send an uplink multiuser trigger frame, and the first device may receive an uplink frame from the second device.

Abstract: Techniques are described for compressing the PUCCH resources reserved for acknowledging downlink data transmissions when those resources are implicitly signaled by EPDCCHs that schedule the downlink transmissions in TDD mode. An acknowledgment resource offset field transmitted in the EPDCCH is configured to correspond to one or more values that compress the region in PUCCH resource index space that would otherwise be reserved for the subframes of a bundling window.

Abstract: Uplink requests for bandwidth and/or other types of communication resources are provided. In some embodiments, a communication device can access a mapping between quality of service (QoS) metrics and communication resources. The communication device can determine a value of the QoS (e.g., a guaranteed rate, a defined traffic priority, an amount of buffered data, etc.) and can determine a communication resource element using at least the mapping and the value of the QoS metric. The communication device also can configure an uplink request for communication resources based at least on the communication resource element. In addition, the communication device can send the uplink request.
