Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may wake up from a sleep mode of a discontinuous reception (DRX) cycle based on receipt of uplink data. The UE may determine if an elapsed time between a prior receipt of one or more reference signals and an uplink transmission to the base station after waking up from the sleep mode is less than a threshold time value. If the elapsed time is less than the threshold time value, the UE may transmit an uplink transmission associated with the received uplink data prior to receiving one or more reference signals that may be used to update transmission parameters for uplink transmissions. If the elapsed time is at or above the threshold value, the UE may wait to receive the one or more reference signals and update the transmission parameters prior to the uplink transmission.

Abstract: Examples described herein relate to enhancing data communication performance in a wireless communication network including a first subscription associated with a first radio access technology (RAT) and a second subscription associated with a second RAT, where the wireless communication device uses a same radio frequency (RF) resource to communicate over both the first RAT and the second RAT. The first RAT is used, in part, for data operations while the second RAT is used, in part, for voice operations. During idle state voice operations, the RF resource is reallocated from performing data operations to performing idle state voice operations, causing interruptions in the data operations. The wireless communication device adjusts at least one or a duration and an occurrence of the idle state voice operations to reduce the impact on the data operations.

Abstract: In a 3GPP LTE-A support for Mobile Type Communications, that is, M2M communications scheme, improvements of the random access are necessary to prevent random channel overload. Enhanced backoff in the presence of overload is such a mechanism, Counting the number of devices seeking RACH based on the number of received random access requests or else responses, and allocating Random Access resources on the basis of the number of requests, is another. Further, a channel aware resource allocation approach provides a way of determining, from the received requests, delay-tolerance of the M2M devices, based on which they are prioritized in accessing the random channel. Even within the prioritized devices, a smaller subset thereof may be prioritized further, according to radio conditions, to provide better access to those with higher SNR RBs.

Abstract: Opportunistic forwarding of packet based communication is implemented by way of attention to link quality to determine a suitable prioritised route for communication. Ranking of potential routes (or the next hop in a route) can be conducted locally, with reference to a link quality metric also. Channel access by nodes of the same rank in a graph based network can be by way of link quality also.
