Принадлежит: Panasonic Corp

The invention relates to methods and apparatuses for providing HARQ feedback in a mobile communication system using carrier aggregation. To suggest a scheme for transmitting feedback on the successful/unsuccessful decoding of transmissions that is operable in FDD mode, the invention proposes to utilize only a single one of plural radio resources available for feedback transmission for signaling feedback for multiple transmissions. A feedback sequence of ACK/NACKs for the transmissions is mapped to one feedback resource combination that is one of the radio resources available for feedback transmission and a modulation symbol of the given modulation scheme that is transmitted on said one radio resource. This scheme can also be used in cases where the number of possible feedback sequences of ACK/NACKs for the transmissions is larger than the number of feedback resource combinations available for feedback transmission.

Bits for acknowledgement (ACK) and/or negative acknowledgement (NAK) may be allocated based on whether a special subframe configuration in a TDD configuration permits downlink transmission. For carrier aggregation, ACK/NAK bits may be allocated only to special subframes in component carriers (CCs) which permit downlink transmission. Also, for example, ACK/NAK bits may be allocated to all CC special subframes if a single CC is configured to allow downlink transmission on one of its special subframes.

In a serial communication interface with transceivers that run on different clocks, an ACK transmit FIFO is used to track packets transmitted, and an ACK receive queue is used to track ACK bits for received packets. The ACK receive queue contains a number of entries, and training for the transceivers begins transmitting ACK bits from the ACK receive queue once the ACK receive queue has multiple valid ACK bits. When the ACK receive queue is less than a lower threshold, an ACK compensation mechanism sends one or more packets that make the ACK receive queue grow.

This disclosure provides methods, devices and systems for enhanced bandwidth puncturing. Some implementations more specifically relate to punctured channel indications that support channel puncturing over a range of bandwidths achievable in accordance with the Institute of Electrical and Electronics Engineers (IEEE) 802.11be amendment, and future generations, of the IEEE 802.11 standard. In some implementations, an access point (AP) may communicate static punctured channel information to each associated wireless station (STA) in its BSS. In some other implementations, a transmit opportunity (TXOP) holder may communicate dynamic punctured channel information to a TXOP responder with which it intends to communicate. Still further, in some implementations, the TXOP responder may communicate additional punctured channel information to the TXOP holder responsive to the dynamic punctured channel information. 1. A method for wireless communication by a wireless communication device comprising:transmitting, to a wireless station (STA), a management frame carrying punctured channel information indicating one or more first punctured subchannels associated with a wireless channel; andcommunicating with the STA over a portion of the wireless channel that excludes at least the one or more first punctured subchannels.2. The method of claim 1 , wherein the punctured channel information includes a bitmap representing a plurality of subchannels associated with the wireless channel claim 1 , the one or more first punctured subchannels being indicated by one or more bits claim 1 , respectively claim 1 , of the bitmap.3. The method of claim 2 , wherein each bit of the bitmap represents a respective 20 MHz subchannel.4. The method of claim 2 , wherein the bitmap is carried in a non-legacy operation element of the management frame.5. The method of claim 1 , wherein the punctured channel information includes a puncturing mode indication indicating whether a transmit opportunity (TXOP) ...
