In some examples, a wireless device selects a selected rate bucket of a plurality of different rate buckets, a rate bucket of the plurality of different rate buckets comprising a plurality of coding rates. In some examples, the selected rate bucket can include at least one other encoding capability, such as a modulation or a coding scheme.

A network node of a communication network may determine that a target transmission power for a subsequent transmission by the network node is no longer optimal. In response to the determination, the network node may autonomously modify one or more parameters of the subsequent transmission, from a modulation and coding scheme (MCS) and/or a set resources for the subsequent transmission. The network node may then transmit a channel, based at least in part on the one or more modified parameters, to a target network node in the subsequent transmission. The target network node may determine that the network node has autonomously modified the one or more parameters of the transmission, from the modulation and coding scheme (MCS) and/or the set resources for the transmission. The target network node may process the transmission based on the determination.

A technique is described for selecting an encoder to encode video captured by a network-connected camera system based on characteristics of deployment of the network connected cameras system. The network-connected camera system may include one or more cameras and a base station connected to each other via a network, which can be a wireless network. A processing system, for example at the base station, receives data indicative of characteristics of deployment of the network-connected camera system, processes, the received data to select an encoder, and causes the one or more cameras to process captured video using the selected encoder. In some embodiments, encoder selections can be continually updated based on changes in the deployment of the network-connected camera system.

Disclosed is a method for a terminal to receive downlink control information (DCI) in a wireless communication system. In particular, the method comprises: receiving information related to a mapping relation between a blind decoding candidate index and a redundancy version (RV) for DCI; detecting DCIs repeatedly transmitted in a plurality of blind decoding candidates; acquiring an RV value of the DCI on the basis of the information and the index of the blind decoding candidate in which the DCI has been detected, and acquiring data scheduling information included in the DCI on the basis of the RV value.

Example HARQ-based transmission methods and apparatus are provided, to meet transmission requirements of different services. In one example method, a network device receives a QoS parameter that is of a service corresponding to a service request and that is delivered by a core network device. The network device determines, based on the QoS parameter of the service, a HARQ configuration parameter corresponding to the service, and notifies the HARQ configuration parameter to the terminal device. Therefore, when different services are transmitted between the network device and the terminal device, different HARQ configuration parameters are configured for different services, and data transmission and retransmission of a service are performed based on a configured HARQ configuration parameter, so that transmission requirements of different services can be met.

A device and method and system for dynamically processing a random access response (RAR) signal to perform wireless communications is disclose. In some embodiments, the device is configured to receive one or multiple random access response (RAR) signals, wherein when the processor receives multiple RAR signals, it selects a RAR signal and responses to the selected RAR signal based on a content of the one or multiple RAR signals and proceeds with subsequent wireless communication using information contained in the selected RAR signal.

Aspects of this disclosure relate to cooperative multiple-input multiple-output (MIMO) downlink scheduling. Features are described for scheduling transmissions within a MIMO network to efficiently allocate resources considering the needs and/or characteristics of devices served by the network. The downlink mode or active set may be scheduled based at least in part on the channel state information and additional network system information detected by or otherwise available to the scheduling device.

In one embodiment, a method includes identifying, by a packet analyzer, one or more silence packets within a network and initiating, by the packet analyzer, a replacement of the one or more silence packets with one or more performance silence packets. The one or more performance silence packets are transmitted between a first node of the network and a second node of the network during a silence period. The method further includes receiving, by the packet analyzer, information associated with the one or more performance silence packets; and analyzing, by the packet analyzer, a connection between the first node of the network and the second node of the network using the information associated with the one or more performance silence packets.
