摘要： Systems, devices, and techniques for beamforming in wireless communication systems are described. A described technique performed by a user equipment (UE) includes monitoring a downlink reference signal from a base station; transmitting, via a physical uplink shared channel (PUSCH) associated with a hybrid automatic repeat request (HARQ) process number, a beam failure recovery request (BFRQ) in response to a change in a quality of the downlink reference signal, wherein the BFRQ comprises new beam information; receiving, by the UE, a downlink control information (DCI) message to trigger a PUSCH transmission corresponding to the HARQ process number; and transmitting, by the UE after at least a predetermined number of symbols from a last symbol of a physical downlink control channel (PDCCH) reception containing the DCI message, information via a PUCCH in accordance with the new beam information. The UE can apply the new beam information to uplink and downlink channels.

摘要： An electronic device (such as an access point) is described. This electronic device transmits an orthogonal frequency division multiple access (OFDMA) frame to a recipient electronic device (such as a client or a station). The OFDMA frame includes multiple predefined resource units (RUs) allocated to the recipient electronic device in a set of predefined RUs having associated frequency bandwidths. Moreover, the multiple predefined RUs include two or more first predefined RUs having a first number of tones less than a predefined amount, or two or more second predefined RUs having a second number of tones greater than or equal to the predefined amount. For example, the predefined amount may include 242 tones. Note that the multiple predefined RUs may have the same or different numbers of tones. Moreover, the electronic may receive an acknowledgment or a block acknowledgment from the recipient electronic device.

摘要： A method performed by a STA may comprise transmitting a first negotiation message to an AP and receiving a second negotiation message from the AP. The first negotiation message and the second negotiation message may negotiate a block acknowledgement agreement. The method may further comprise receiving a data unit, from the AP, the data unit having a duration field indicating a duration of a block-ACK frame. The duration of the block-ACK frame may be determined based on the negotiated block ACK agreement. A block-ACK frame may be transmitted within the duration indicated by the duration field.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) receives an initial transmission of a common codeword and a private codeword. The common codeword is common to the UE and at least one other UE. The private codeword is directed to the UE. An acknowledgement is transmitted indicative of decoding results of the common codeword and the private codeword based on results of whether the common codeword was successfully decoded and whether the private codeword was successfully decoded. At a Network Entity (NE), an initial transmission of the common codeword and the private codeword is sent and an acknowledgement is received indicative of decoding results. At least one of the common codeword or the private codeword can be retransmitted depending on the acknowledgement.

摘要： A method for facilitating frame error handling and an electronic device are provided. The method is for use in an electronic device capable of communicating with another electronic device. The method comprises the following. In response to an error event in an advanced line encoding mode, closing a first burst transmission and opening a second burst transmission are performed, wherein the advanced line encoding mode indicates that the electronic device is capable of data transmission by using an advanced line encoding having an improved effective data rate as compared to 8b/10b encoding. A lane alignment pattern is transmitted in the advanced line encoding mode from the electronic device to the other electronic device after the second burst transmission is opened. A negative acknowledgement control frame is transmitted in the advanced line encoding mode from the electronic device to the other electronic device after the lane alignment pattern is transmitted.

摘要： Aspects of the present disclosure provide techniques to expedite transmissions of hybrid automatic repeat request (HARQ) acknowledgment or negative acknowledgment (ACK/NACK) feedbacks based on delay constraints associated with at least semi-persistent scheduling (SPS) downlink packets received at the user equipment (UE). Specifically, in accordance with aspects of the present disclosure, each of the one or more SPS PDSCH configurations may be associated with a delay parameter that identifies the maximum amount of time or slots that the UE can wait prior to transmitting the HARQ-ACK/NACK feedback associated with the PDSCH received at the UE.
