摘要： Embodiments of the present invention disclose a polar code processing method and communications device. The method includes: obtaining, based on a target coded bit quantity M and preset first mapping relationship information, a first sequence number set of M uncoded bits that is corresponding to the target coded bit quantity M, the first mapping relationship information is used to indicate a one-to-one correspondence between a plurality of coded bit quantities and a plurality of uncoded bit sequence number sets, the M uncoded bits include K information bits, and M target coded bits are obtained after polar encoding is performed on the M uncoded bits; and selecting, from the first sequence number set of the M uncoded bits according to a preset first selection rule, K sequence numbers as a sequence number set of the K information bits. In the embodiments of the present invention, only a correspondence between a coded bit length 2 n and an uncoded bit sequence number set may be included. Therefore, storage space is greatly saved, and encoding/decoding efficiency of a polar code is improved.

摘要： A method and apparatus for transmitting control information in a wireless communication system is provided. The number of LDPC blocks, through which L1 post-signaling information is to be transmitted, is determined according to the total number of bits of the L1 post-signaling information. The number of input information bits of each LDPC block is calculated when the determined number of LDPC blocks is plural. The number of puncturing bits among parity bits of each LDPC block is determined considering a modulation order. A frame including one or multiple LDPC blocks generated through the preceding steps is transmitted.

摘要： Fast channel changing in digital-television-based entertainment networks can be implemented, for example, by electing to tune to channels at opportune tuning times. In an exemplary implementation, a method includes: receiving a channel change request that indicates a requested new channel from a client device; preparing a broadcast video data stream of the requested new channel that is offset in time behind a current broadcast time for broadcast video data of the requested new channel; and streaming the broadcast video data stream responsive to the channel change request. In another exemplary implementation, a system includes: a storage device (408A) that retains broadcast video data (410) for multiple channels; a video data extractor (416) that accesses the retained broadcast video data and retrieves an intra frame of broadcast video data that is in the past for a requested channel; and a video data distributor (418) that transmits the retrieved intra frame of broadcast video data.

摘要： Disclosed is a method and apparatus for providing uplink packet data services through an E-DCH in an asynchronous WCDMA system. A transport block size (TBS) for transmitting uplink transport channel data is determined. A combination of a spreading factor and a modulation scheme for uplink channel data transmission, corresponding to the determined TBS, is selected according to transmittable physical channel data bit sizes and puncturing limit values. The TBS is transmitted by incorporating it into control information of the uplink transport channel data. The modulation scheme and spreading factor combination is determined based on a physical channel data bit size that maximizes transmission efficiency and minimizes the number of punctured bits, without requiring an additional physical channel in transmitting the uplink data having the TBS. This method maximizes uplink transmission efficiency to save transmission resources and reduces signaling overhead required to transmit E-DCH control information.

摘要： Methods and apparatus for encoding control information with subsequent puncturing are disclosed. Control information generated by a user equipment (UE) is provided, where the control information comprises a first bit sequence, a second bit sequence, and a third bit sequence (1804). The method comprises: arranging said bit sequences to produce a bit sequence XI (1806); padding the bit sequence XI with a bit sequence P to produce a bit sequence XI' (1808); convolution encoding the bit sequence XI' to produce an encoded bit sequence Zl (1810); and puncturing the bit sequence Zl using a predefined puncturing pattern to produce a bit sequence Rl (1812), wherein the predefined puncturing pattern is a rotationally symmetric puncturing pattern (700,900). The control information may comprise CQI/PCI reports, which may be transmitted on a HS-DPCCH.
