Номер: RU2546613C2

Изобретение относится к системам беспроводной связи, а более конкретно, к управляющим сигналам. Технический результат - надежный обмен управляющими сигналами для реализации эффективных систем беспроводной связи. Для этого PDCCH нисходящей линии связи передается таким способом, который сдерживает UE от декодирования PDCCH на нескольких уровнях агрегирования. Неоднозначные размеры полезной нагрузки идентифицируются и модифицируются через дополнение нулями с помощью одного или более битов на основе размера полезной нагрузки. Последовательности скремблирования уровня агрегирования могут быть сформированы так, что приемное UE может точно идентифицировать уровень агрегирования, на котором следует декодировать PDCCH. Биты индикатора, которые сигнализируют уровень агрегирования в UE, также могут быть включены в PDCCH. 6 н. и 12 з.п. ф-лы, 16 ил.

Aggregation level scrambling sequences can be generated such that a receiving UE can accurately identify the aggregation level on which to decode the PDCCH. Indicator bits that signal the aggregation level to a UE can also be included in the PDCCH.

Padding data streams according to channel capacity

In a packet switched network (100) in which channels between nodes (104, 118) are shared by Voice over Internet Protocol (VoIP) data packets and other data packets, data streams are encoded (208) and padded (212) so as not to exceed the capacity of the channel, as monitored by a bandwidth management module (206), without use of an adaptive bit rate codec. The capacity of the channel is probed by incrementing the transmitted bit rate from a low bit rate (eg. 8kb) by adding padding bits and monitoring their effect on eg. round-trip times or buffer levels until a target rate (eg. 64kb) which avoids both overload and excessive latency is achieved.

An access point (AP) may determine frame extension lengths for use in transmitting to stations (STAs) based on reception capabilities of the STAs. An AP may determine frame extension lengths for STAs to use in transmitting frames.

METHODS OF RELIABLY SENDING CONTROL SIGNAL

Номер: CA0002827965C
Принадлежит: QUALCOMM INCORPORATED, QUALCOMM INC

Downlink PDCCH is communicated in a manner that mitigates a UE from decoding the PDCCH on multiple aggregation levels. Ambiguous payload sizes are identified and modified through zero padding with one or more bits based on the payload size. Aggregation level scrambling sequences can be generated such that a receiving UE can accurately identify the aggregation level on which to decode the PDCCH. Indicator bits that signal the aggregation level to a UE can also be included in the PDCCH.

The disclosure relates to a method for serially transmitting a frame from a transmitter to at least one receiver via a bus line, as well as a subscriber station for a bus system. According to said method, stuff bits for generating additional signal edges are inserted into the frame by the transmitter according to a predetermined rule, and the stuff bits are removed again by the receiver when evaluating a received frame, a CRC calculation logic of a CRC generator calculating a CRC checksum that is comprised by said frame, and a value of “1” being inserted into said CRC calculation logic in an additional evaluation step if a value of “0 . . . 0” has been determined for the CRC checksum in the running calculation executed by the CRC calculation logic. 1. A method for serial transmission of a frame , the method comprising:transmitting the frame from the from a transmitter to a receiver via a bus line;inserting, before the transmitting, stuff bits into the frame with the transmitter according to a predetermined rule to generate additional signal edges;removing, after the transmitting, the stuff bits with the receiver in an evaluation of the frame;calculating a CRC checksum with a CRC calculation logic of a CRC generator, the frame including the CRC checksum; andinserting a value “1” into the CRC calculation logic in an additional evaluation step in response to a value of “0 . . . 0” being found for the CRC checksum in the calculating carried out by the CRC calculation logic.2. The method as claimed in claim 1 , wherein the additional evaluation step is carried out before an evaluation of a next transmitted bit.3. The method as claimed in claim 1 , wherein an initialization vector of the CRC checksum has a value “1 . . . 0”.4. The method as claimed in claim 1 , wherein at least one of:the frame includes a header part, a data part, and an end part; andthe frame includes a header part having an identifier.5. The method as claimed in claim 1 , wherein the frame is one of a ...

Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to Wi-Fi systems including frame extensions in transmission frames. Lengths of frame extensions may be determined based on transmission bandwidths and transmission data rates of the frames. Lengths of frame extensions may also be determined based on an amount of useful data in a final symbol of the frame. An access point (AP) may determine frame extension lengths for use in transmitting to stations (STAs) based on reception capabilities of the STAs. An AP may determine frame extension lengths for STAs to use in transmitting frames. 1. An apparatus for wireless communication , comprising:a processing system configured to generate a frame for transmitting data to one or more wireless nodes, to determine whether to include a frame extension after a data symbol in the frame, and to provide an indication of a length of the frame extension within the frame, if the determination is to include the frame extension; anda first interface configured to output the frame for transmission.2. The apparatus of claim 1 , wherein the determination whether to include a frame extension is based on at least one of a transmission bandwidth or a transmission data rate for transmitting the frame.3. The apparatus of claim 1 , wherein the processing system is configured to determine the length of the frame extension based on an amount of data in the data symbol of the frame.4. The apparatus of claim 3 , wherein the processing system is further configured to determine the length of the frame extension based on a ratio of coded data bits in the data symbol to total coded bits in the data symbol.5. The apparatus of claim 4 , wherein:the indication is provided as one or more bits;different combinations of values of the one or more bits correspond to different quantized values of the ratio; andthe different quantized values of the ratio correspond to different frame extension lengths.6. ...

User Equipment and Flexible Protocol Data Unit Packaging Method Thereof

Номер: US20180302823A1
Принадлежит: MediaTek Inc

A user equipment (UE) and a flexible protocol data unit (PDU) packaging method thereof are provided. The user equipment performs a flexible PDU packaging procedure in a radio link control (RLC) layer when receiving configuration information that configures a 7-bit length indicator (LI) size and a flexible PDU size from a base station. The user equipment uses an exactly-filled LI to indicate the end of a service data unit (SDU) occurring at the end of the previous one PDU and an accumulated SDU size of the previous one PDU exceeds 123 octets. In addition, the user equipment utilizes a special value of a header extension (HE) field or an alternative E-bit of the header to indicate that the PDU includes only one SDU and the SDU is a complete SDU.
