In some embodiments, the method includes (i) determining, among a plurality of data stack solutions that are selectable, which layer-2 data stack solution is selected and (ii) causing, according to the selected layer-2 data stack solution, the layer-2 micro controller to intervene with a data plane hardware module that is configured to implement a specific layer-2 data stack function. Each of the plurality of data stack solutions represents a distinctive intervening configuration of a layer-2 micro controller. The layer-2 micro controller is coupled to a number of data plane hardware modules that are configured to implement different layer-2 data stack functions. The intervening configuration of the layer-2 micro controller is indicative of a level of control of the layer-2 micro controller over the data plane hardware modules.

Contention resolution for the user equipment can be concluded with only the first message and the second message.

Contention resolution in wireless communication systems

Introduced here are techniques for reducing the average throughout of a baseband (BB)-radio frequency (RF) interface. The techniques include removing excess bits from a received signal based on the signal to noise ratio (SNR), rotating the reduced signal to direct current frequency, and applying a coding scheme to further compress the signal. After compression, the signal can be transmitted from one chip to another. The receiving chip can retrieve the signal by rotating the signal to its original frequency and retrieving the removed bits based uplink gain information. By doing so, the number of bits being transmitted is reduced and thus, the average throughput of the BB-RF interface is also reduced.

Power saving techniques for BB-RF interface

Introduced here are approaches to classifying traffic that comprises data packets. For each data packet, a classification engine implemented on a computing device can identify an appropriate class from amongst multiple classes using a lookup table implemented in a memory. The memory could be, for example, static random-access memory (SRAM) as further discussed below. Moreover, the classification engine may associate an identifier with each data packet that specifies the class into which the data packet has been assigned. For example, each data packet could have an identifier appended thereto (e.g., in the form of metadata). Then, the data packets can be placed into queues based on the identifiers. Each queue may be associated with a different identifier (and thus a different class).
