Uplink control information reporting
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to communicate with a base station on different channels or messages with different processing timelines. In order to prevent a collision between processing communications associated with the different length TTIs, the UE may drop one or more communications on corresponding channels with longer processing timelines to receive and/or process the transmission on the channel with a shorter processing timeline. Additionally, the UE may transmit uplink control information (UCI) for the one or more dropped communications, where the UCI may include hybrid access request (HARQ) acknowledgement/negative acknowledgement (ACK/NAK) feedback, channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), etc. If a downlink transmission is dropped, the UE may transmit a NAK message. Alternatively, if an uplink transmission is dropped, the UE may transmit at least a portion of the UCI.
Acknowledgment feedback techniques in wireless communications
Methods, systems, and devices for wireless communications are described that provide for unambiguous mapping between downlink control channel transmissions, downlink shared channel transmissions, and uplink acknowledgment feedback resources. The uplink acknowledgment feedback resource may be located within a same transmission time interval (TTI). A base station may configure codebook-based acknowledgment resources from a user equipment (UE), and feedback delay values may be associated with time domain resources of the downlink shared channel transmissions. In some examples, feedback delay values may be associated with particular search spaces or monitoring occasions of the downlink control channel transmissions that include resource allocations for the downlink shared channel transmissions. A UE using codebook-based acknowledgment feedback resources may thus unambiguously identify uplink resources that are to be used for transmitting the uplink acknowledgment feedback.
Beam failure detection and recovery for sidelink user equipments
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving (Rx) user equipment (UE) may receive, from a transmitting (Tx) UE, sidelink control information (SCI). The Rx UE may determine an Rx-side block error rate (BLER) based at least in part on the SCI. The Rx UE may perform a beam failure recovery based at least in part on the Rx-side BLER satisfying a threshold. Numerous other aspects are described.
Detection of inconsistent data in a data transmission
The present disclosure provides methods and apparatus for detecting when a data transmission has been preempted or punctured by detecting inconsistency in the modulation or other signal characteristic of a received signal. If an inconsistency is detected, measures can be taken to mitigate potential problems caused by the inconsistent data. In one example, the receiving device (30) may identify soft bits in a soft buffer that may have been corrupted and flush the corrupted parts from the soft buffer.
Communication-information measuring device and non-transitory computer readable medium
An information terminal sequentially transmits one or more packets to an information distribution server, receives acknowledgments for the transmitted packets from the information distribution server, and records a round trip time and occurrence of packet loss for each of the transmitted packets. Among one or more packet sequences, the information terminal counts the number of packet sequences which are such that the number of packet losses included in each of the packet sequences and an increase state of the round trip time for packets included in the packet sequence satisfy respective predetermined conditions. Each of the one or more packet sequences has multiple continuous packets including one or more packets, for which packet loss is recorded among the transmitted packets, at the top. The information terminal calculates a packet loss ratio on the basis of the counted number and the number of transmitted packets.
Sequence number update
The invention relates to a method and device in a communications network when a User Equipment, UE, needs to update a next expected Transmission Sequence Number, TSN, continuously in order to avoid discarding successive transmissions. The method comprises: resetting a next expected TSN value in said network and UE to predetermined values after a predetermined inactivity time.
METHOD, SYSTEM, COMPUTER DEVICE, AND STORAGE MEDIUM FOR NON-CONTACT DETERMINATION OF A SENSING BOUNDARY
A method and a system are for non-contact determination of a detection boundary. A Wi-Fi receiving device simultaneously receives data packets by using any two antennas, and measures channel state information; conjugate multiplication is performed on the CSI measured at a moment corresponding to reception of the two antennas, to obtain a new CSI signal stream; a time window with the length M is selected from the new CSI signal stream, and M CSI samples in the time window are collected, to form a conjugate set; the mean of the conjugate set is subtracted from all the samples in the conjugate set, to obtain a zero-mean conjugate set; N zero-mean conjugate sets are obtained for CSI on N sub-carriers simultaneously transmitted; and probability distribution fitting is performed on the absolute values of all elements in the N zero-mean conjugate sets, to calculate a boundary detection feature.
Entity Establishment Processing Method and Apparatus
An entity establishment processing method and an apparatus are provided. The processing method includes: A terminal side device receives first indication information from a first network side device, where the first indication information is used to trigger reestablishment of a first PDCP entity of the terminal side device. When a first bearer corresponding to the first PDCP entity is not a radio bearer used to perform duplication transmission between the terminal side device and a core network side device, in a process in which the terminal side device reestablishes the first PDCP entity based on the first indication information, the terminal side device sets a parameter of the first PDCP entity to an initial value.
PRECLUSIVE DATA DECOMPRESSION FAILURE TECHNIQUES
Preclusive data decompression failure techniques, such as may avoid data decompression failures using predictive decompression failure indications and/or configure communication devices for data transmission recovery before reordering window timer expiration, are described. Preclusive data compression failure operation may, for example, initiate compressor memory resets conditionally according to some aspects of the present disclosure, such as using one or more trigger events to predictively indicate decompression failure. Additionally or alternatively, preclusive data compression failure operation may provide for configuring communication devices for data transmission recovery before reordering window timer expiration, such as configuration for prioritization to provide data transmission recovery before reordering window timer expiration. Other aspects and features are also claimed and described.
Contention window adjustment for multiple transmit receive points
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first transmit receive point (TRP) may transmit a first physical downlink shared channel (PDSCH) communication to a user equipment (UE), wherein the first PDSCH communication includes a first set of layers for a codeword, and wherein a second set of layers for the codeword are transmitted to the UE in a second PDSCH communication from a second TRP. The first TRP may receive from the UE, acknowledgement or negative acknowledgement (ACK/NACK) information corresponding to the codeword. The first TRP may adjust a contention window size based at least in part on a determination that a condition, associated with the ACK/NACK information, is satisfied. Numerous other aspects are provided.
