Abstract: An eNodeB operable to maintain timing advance groups (TAGs) in a heterogeneous network (HetNet) is disclosed. The eNodeB can form a timing advance group (TAG) for one or more serving cells when a same timing advance applies to the one or more serving cells. The eNodeB can map each of the one or more serving cells to the TAG using radio resource control (RRC) signaling from the eNodeB. The eNodeB can assign a timing advance group identifier (TAG ID) to the one or more serving cells mapped to the TAG. A separate timing advance timer can be maintained at a user equipment (UE) for each TAG for a selected period of time.

Abstract: A wireless communication device (UE) may reliably decode control information during wireless cellular communications. The UE may decode the Physical Control Format Indicator Channel (PCFICH) for a given wireless network, and if the decode is unsuccessful, the UE may perform a blind decode of the PCFICH. The UE may decode, for the network, a Physical Downlink Control Channel (PDCCH) for a current subframe using a specified control format indicator (CFI) value. If the decode of the PDCCH is successful, the UE may communicate over the NW, using the specified CFI value. If the decode for the current subframe is unsuccessful, the UE may decode the PDCCH for a different next subframe using a different CFI value until the PDCCH for the NW has been successfully decoded. The CFI value may be specified based at least on common signaling present in certain subframes received by the UE.

Abstract: Embodiments are provided for uplink measurement based mechanism and control using user equipment (UE) centric sounding signals. The mechanism provides an alternative to DL-measurement dominated system control. Based on UL-measurements at TPs, the network obtains knowledge of users' channel and timing information, traffic, and interference, and is thus able to perform better control, including TP and UE clustering and optimization, and power control and link adaptation. In an embodiment method, a TP receives one-to-one mapping information indicating a plurality of UE IDs and a plurality of sounding channels assigned to the corresponding UE IDs. When the TP detects a sounding reference signal (SRS) from a UE, the TP is able to identify the UE using the detected SRS and the one-to-one mapping information. The TP then obtains measurement information for the identified UE, enabling better control and communications for uplink and downlink transmissions between multiple TPs and the UE.

Abstract: Methods and systems are disclosed that support the aggregation of acknowledgement messages and control messages. Advantageously, acknowledgement and negative acknowledgement indications for multiple client nodes are combined into a single aggregated message which is broadcast or multicast to the multiple client nodes. Based on unique identifiers assigned to each client node, client nodes are grouped such that the aggregated acknowledgement messages can be efficiently encoded to conserve both network capacity when they are transmitted, as well as processing capacity when they are parsed by the client nodes. If code division multiple access (CDMA) technology is used, the aggregated acknowledgment message can be transmitted without CDMA spreading to effectively broadcast or multicast it to multiple client nodes. A similar technique can be employed for the efficient broadcast or multicast of aggregated control messages.
