Abstract: Cells are grouped into a plurality of timing advance groups (TAGs) and a plurality of physical uplink control channel (PUCCH) groups. The PUCCH groups comprise a primary PUCCH group comprising a primary cell and a secondary PUCCH group comprising a PUCCH secondary cell. The PUCCH secondary cell is in a first TAG. When a time alignment timer of the first TAG expires, the wireless device notifies a radio resource control layer to release the secondary PUCCH, and stops transmission of positive acknowledgement or negative acknowledgement for a downlink HARQ process of an activated cell in the secondary PUCCH group.

Abstract: Embodiments include a method, computer program product, and system for grouping electronic devices into contention groups to reduce uplink Orthogonal Frequency-Division Multiple Access (OFDMA) random access (OFDMA-RA) collisions. An access point may explicitly assign an electronic device to a contention group, or the electronic device may implicitly determine an assignment to the contention group. To explicitly assign a device to a contention group, the access point may randomly assign or assign based on a criteria of the electronic device. Examples of criteria include an association identifier (AID), a traffic type/quality of service (QoS) category, a power saving preference, and an association status. The electronic device may implicitly determine a contention group assignment based on the total number of contention groups.

Abstract: A Time and Frequency Division (TaFD) scheduler based on a TaFD allocation unit based credit allocation may schedule both time and frequency division for both legacy Data Over Cable Service Interface Specification (DOCSIS) channels and DOCSIS orthogonal frequency division multiple access (OFDMA) channels. In embodiments, scheduling by the TaFD schedules both single carrier quadrature amplitude modulation (SC-QAM) transmissions and OFDMA upstream transmissions.

The credits may be dynamically adjusted based on channel utilization and an outstanding bandwidth demand or a prioritized pending bandwidth demand. The TaFD scheduler may use independent hierarchy priority queuing schemes.
