Abstract: Compressed modulation feedback in codeword transmission with per-layer-modulation mapping is discussed. In the proposed compression schemes, the number of bits of feedback is compressed by excluding some of the allowed combinations of per-layer modulation orders. The excluded combinations are determined according to a fixed index delta, which prohibits any one modulation scheme being selected that has an index difference greater than the fixed index delta. The transmitting entity may then send per-layer modulation parameters, which may be the actual modulation orders identified or some relative parameter.

Abstract: Data communication apparatus and methods for a multi-wire interface are disclosed. A half rate clock and data recovery (CDR) circuit derives a clock signal including pulses corresponding to symbols transmitted on a 3-wire interface, where the symbols are transmitted at a particular frequency with each of the symbols occurring over a unit interval (UI) time period. The first clock signal is input to a flip-flop logic included in a delay loop, and serves to trigger the first flip-flop logic. A second clock signal is generated using a programmable generator in the delay loop and has a frequency of a half UI and is fed back to a data input of the flip-flop. The output of the flip-flop is used as a recovered clock signal for the CDR at a half rate frequency. This design provides ease of timing control, a delay line without extra nonlinear-effects, and less hardware overhead.

Abstract: A method, computer-readable medium, and apparatus operate to reduce or eliminate interference with one or more other communication systems having specific transmission requirements within a specific geographic area. For example, aspects operate by determining that a user equipment (UE) is in a protection zone where additional transmission requirements apply. The additional transmission requirements enable coexistence with one or more other communication systems in the protection zone. The UE may identify, based on being in the protection zone and a coexistence mode, one or more transmit emission limit requirements to be met. The UE may identify, based on being in the protection zone and the coexistence mode, one or more maximum transmit power requirements to be met. The UE may configure a transmit output power, at which the UE can meet the one or more transmit emission limit requirements and the one or more maximum transmit power requirements.

The UE may receive a page message, and initiate an access procedure that may be used for transmission of the small data. The UE may be in idle mode prior to the small data transmission, and in some examples may return to idle mode following the transmission of the small data.

Abstract: Techniques for managing access to a shared communication medium are disclosed. Scheduling grants may be sent to different access terminals for different sets of resources for uplink transmission on the communication medium. A series of re-contention gaps may be scheduled for access terminal contention within or between the different sets of resources.

Moreover, an access terminal may receive a scheduling grant that allocates a set of resources to the access terminal for uplink transmission on a communication medium and contend for access to the communication medium based on the scheduling grant. The access terminal may then selectively transmit uplink traffic over the allocated set of resources based on the contending.

Abstract: Methods, systems, and devices for wireless communication are described. Different robust header compression (RoHC) schemes may be used when a change in a header extension flag between packets of a communication session is determined. For example, a transmitting device may determine a value of a header extension flag in a packet has changed with respect to header extension flags in preceding packets. Upon detecting the change in the header extension flag, the device may compress the header using different RoHC schemes. For instance, the device may compress the header by reverting to an initialization and refresh (IR) state. Additionally or alternatively, the device may compress the header using a compression profile that refrains from compressing a certain portion of the header. In some cases, the RoHC scheme used for compressing the header may be based on how frequently the value of the extension flag changes between packets.
