Abstract: Efficient methods for wirelessly communicating file content under varying conditions are described. A wireless device determines, based on mobility and/or geographic location, if the wireless device is to operate in a first mode of communication operation in which received portions of said file are re-transmitted or a second mode of communication operation in which combinations of portions of said file are transmitted. The wireless device transmits packets communicating received file portions when it is determined that the wireless device is to operate in said first mode of operation and transmits packets communicating combinations of file portions, e.g., linear combinations of file portions, when it is determined that the wireless device is to operate in said second mode of operation. The contents of a file may be obtained from some packets which communicate distinct portions of the file and other packets which communicate combinations of distinct portions of the file.

Abstract: Techniques are provided for expedited Internet content delivery. For example, there is provided a method that involves receiving, at a communication device, a broadcast transmission outside of a spectrum allocated for Internet communications and outside of a spectrum allocated for real time programming content, wherein the broadcast transmission includes unsolicited content pushed to a group of such communication devices. The method may involve storing a portion of the unsolicited content, and receiving a request for content from a user. The method may involve providing the portion of the unsolicited content to the user, in response to the requested content matching the portion. The method nay involve determining whether the requested content is stored on another communication device of the group, in response to the requested content not matching the portion.

Abstract: Techniques are described for wireless communication. In one method, a user equipment (UE) receives a timing synchronization signal (TSS) and a physical broadcast channel (PBCH), with the TSS based at least in part on a timing of the TSS within a broadcast channel transmission time interval (BCH TTI); determines the timing of the TSS within the BCH TTI; and demodulates the PBCH based at least in part on the TSS. In another method, a base station allocates resources for a TSS and a PBCH within a BCH TTI; determines the TSS based at least in part on a timing of the TSS within the BCH TTI; and transmits, on the resources allocated for the TSS and the PBCH, the TSS and the PBCH, with the TSS transmitted as a demodulation reference signal (DMRS) for the PBCH on at least one port used to transmit the TSS and the PBCH.

Abstract: Methods, systems, and devices for wireless communication are described. A network device, such as a base station, may transmit a request message to a user equipment (UE). The request message may include a request for the UE to transmit a set of sounding reference signals (SRSs). The set of SRSs may include two (or more) beamformed signals. The network device may receive the set of SRSs according to the request message. The network device may identify, based on a co-phasing parameter associated with the two (or more) beamformed signals, an antenna port precoder configuration to use for communicating with the UE.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may initiate a beam management procedure, including reference signal transmission to a user equipment (UE) and receive beam training. A base station may configure a UE to monitor a set of beams for reference signals. Based on the received reference signals, the UE may optionally select one or more transmit beams for wakeup signal reception, and may transmit an indication of the selected beams to the base station. The base station may transmit a wakeup signal over the originally configured or the UE-selected transmit beams to initiate wake-up procedure at the UE. The base station and UE may subsequently perform a refined beam management procedure, providing a refined reference signal transmission from the base station. Based on the received transmission, the UE may select a refined beam for downlink transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may initiate handover from one base station to another. The handover procedure may not include random access channel (RACH) transmissions, and thus may be a localized RACH-less handover. The UE may initiate handover to a new base station based on the relative location of the UE and the new base station, some predetermined time, or based on the characteristics of the signals from each base station.
