Abstract: A wireless device may selectively add padding to an end of a data transmission in order to provide adequate time for a receiving device to process the transmitted data and transmit feedback related to the transmitted data. A wireless device may identify a total amount of data capable of being transmitted in a transmission, and determine a number of data bits to be transmitted in the transmission. An amount of padding may be selected based on a proportion of the total amount of data capable of being transmitted and the number of data bits. In some examples, a preamble for a feedback transmission may be transmitted concurrently with processing of the received transmission.

Abstract: Methods and apparatuses for providing wireless messages can include, for example, an apparatus configured to provide wireless communication. The apparatus includes a memory that stores instructions and a processor coupled with the memory and configured to execute the instructions to select a dual sub-carrier modulation (DCM) mode or a non-DCM mode. The processor is further configured to select one or more interleaver parameters based on the selection of the DCM mode or the non-DCM mode. The processor is further configured to select a first set of interleaver parameters when the DCM mode is selected and a second set of interleaver parameters, different than the first set of interleaver parameters, when the non-DCM mode is selected. The processor is further configured to apply the one or more interleaver parameters to interleave data of a message. The processor is further configured to provide the message for transmission to a receiving device.

Abstract: Aspects are described for modifying transmission of control channel signaling during wireless communication. The described aspects include detecting a communication condition corresponding to signaling information transmitted on a Dedicated Channel (DCH); determining whether a Dedicated Physical Data Channel (DPDCH) is transmitted based on detecting the communication condition; and performing a Dedicated Physical Control Channel (DPCCH) gating pattern in response to the determination that the DPDCH is not transmitted, wherein performing the DPCCH gating pattern includes intermittently transmitting the DPCCH when one or more signaling radio bearers (SRBs) are not being transmitted.

Abstract: Methods and systems for wireless communication are disclosed. In one aspect, a method includes generating device specific transmission control information for each of two devices, transmitting the transmission control information for each device over different frequencies, and transmitting data to each of the devices as part of a communication according to the respective transmission control information. In some aspects, the transmission control information for each device is encoded based on an identifier of the device. For example, in some aspects, an error detection value such as a cyclic redundancy check, is exclusive or'ed with an identifier of the device, such as an AID, PAID, or group identifier. The resulting value is transmitted along with the transmission control information. A device receiving the wireless frame may only be able to decode its own transmission control information, as the decoding is also based on the receiving device's identifier.

Abstract: Techniques are described for wireless communication. One or more wireless local area network (WLAN) preamble portions may span multiple 20 MHz frequency bands, and may be duplicated across a transmission bandwidth. WLAN preamble portions may include common portions for multiple receivers as well as dedicated portions for particular receivers, and common portions may be transmitted in a primary frequency band in some examples. Some techniques provide that WLAN preamble portions may be encoded using different sized code blocks. Various aspects of the disclosure also provide for signaling of resource allocations of WLAN wireless frames.

Abstract: Techniques are described for wireless communication. A method for wireless communication at an access point may include identifying a number of stations to receive data from the access point, and generating a downlink frame to transmit the data to the identified number of stations. The downlink frame may include a first signaling field (e.g., a wireless local area network (WLAN) signaling field) directed to the identified number of stations. The first signaling field may include a first segment and a second segment. The first segment may include information common to each of the identified number of stations. The second segment may include at least one information block. Each information block may be separately encoded for each of the identified number of stations. The method may also include transmitting the downlink frame to the identified number of stations.

Abstract: Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, an E-TFC selection process for selecting a transport format combination for an uplink MIMO transmission may take certain steps in the case that a UE is power- or buffer-limited. For example, in a rank 2 transmission, non-scheduled data is allocated only to the primary stream. If the allocated non-scheduled data is less than the determined primary stream transport block size, scheduled data is allocated to the primary stream in an amount not to exceed the determined primary stream TBS. Finally, scheduled data is allocated to the secondary stream in an amount not to exceed the determined secondary stream TBS.
