Abstract: Systems and methods for improved content streaming and downloading. The system enables content to be transmitted to wireless base stations (WBSs) using unicast on the core network side of a cellular network to avoid incompatibilities associated with network broadcast technologies such as Evolved Multimedia Broadcast Multicast Services (eMBMS) and Long-Term Evolution Broadcast (LTE-B). At the same time, the system enable content to be broadcast, or transmitted to multiple user equipment (UE) in a single transmission to reduce wireless bandwidth consumption. The system can include a commodity server to receive requests from WBSs, place them in a chronological list based on network latency, and then transmit content to each WBS in a synchronized unicast manner. Each WBS can then transmit the content to a plurality of UEs with minimal buffer required due to the “pre-synchronization.

The information bit sequence is to be processed into an encoded bit sequence with a target code length M. For a given code rate R, when the length K of the information block is greater than a preset threshold, the information bit sequence is segmented into two or more segments. Each segment is polar encoded into an encoded subsequence. The encoded subsequence has a length that equals to a mother code length Ni, and i=1, 2, . . . , p. Each of the p encoded subsequences is rate matched to obtain a rate-matched encoded subsequence. A rate-matched encoded subsequence i of the p rate-matched encoded subsequences has a code length Mi. The p rate-matched encoded subsequences are concatenated into an encoded bit sequence which has a code length M.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may determine separate uplink (UL) power limitations for multiple transmission time interval (TTI) durations based on distinct power control parameters. In some cases, an adjustment factor or a power backoff may be applied to communications using one TTI duration to ensure that total transmit power does not exceed a threshold. The UE and the serving base station may also identify one or more demodulation reference signal (DMRS) windows. UL data transmissions may be demodulated based on a DMRS sent during the same window. Transmit power control (TPC) commands may be applied at the beginning of each window. However, if an UL transmission is scheduled at the beginning of the window, the UE may wait until a DMRS transmission or until no more transmissions are scheduled for the window before applying the TPC adjustment.
