METHOD TO DECODE UPLINK CONTROL CHANNEL FOR ULTRA RELIABLE LOW LATENCY APPLICATIONS
A method, system and apparatus are disclosed. In one or more embodiments, a network node is configured to communicate with a wireless device (WD). The network node configured to, and/or comprising a radio interface and/or comprising processing circuitry configured to determine if a detected sequence meets one of an acknowledgement (ACK) criterion and negative-acknowledgement (NACK) criterion using at least one bias value where the at least one bias value is based at last in part on a type of service associated with the detected sequence.
Method and apparatus for transmitting uplink signal, and method and apparatus for generating uplink signal in communication system
When a terminal generates an uplink signal in a communication system, the terminal hops a sequence for differentiating itself from another terminal with time. The terminal generates the uplink signal by multiplying a transmission symbol by a sequence of a transmission time corresponding to the transmission symbol.
ACKNOWLEDGMENT REPORTING FOR MULTI-LINK TRANSMISSIONS
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit acknowledgment feedback for a combined signal derived from individual downlink signals received on respective radio links, where the acknowledgment feedback is transmitted with a phase shift applied to the transmission. In some cases, the phase shift may indicate which individual downlink signals were unsuccessfully received and decoded on the respective radio links. For example, the acknowledgment feedback message may include acknowledgment feedback for a final decoding of the combined signal on whether the combined signal is successfully received and decoded and side negative acknowledgment information indicating which individual radio links were unsuccessfully received and decoded via the phase shift. The UE may transmit the acknowledgment feedback on a strongest radio link, a subset of the radio links, or on all of the radio links.
Terminal and communication method to provide communication services
A communication method and a terminal and a base station adapted to the method are provided. The communication method of a terminal includes: receiving a message containing information regarding a semi-persistent scheduling (SRS) configuration from a base station; determining whether a sub-frame configured with a non-adaptive re-transmission is identical to a sub-frame configured with an uplink grant according to the SPS configuration; and when: a sub-frame configured with a non-adaptive re-transmission is identical to a sub-frame configured with an uplink grant according to the SPS configuration; and the terminal does not have data to be first transmitted via the sub-frame configured with an uplink grant according to the SPS configuration, performing the non-adaptive re-transmission.
User equipment and method for resource allocation
To solve a problem that unless all of a plurality of AICH signature states are correctly decoded, the contents of reception results cannot be recognized and the error rate of signature decoding will be high. In this embodiment, a base station uses, out of a signature combination, the signature of at least one predetermined position to indicate information containing a preamble reception result and uses the signature of a position other than the predetermined position to indicate a transmission profile information number of an uplink channel for notification to a user equipment. Thus, the error rate related to reception results can be reduced as compared with the case where a single signature combination is used to notify all pieces of information.
Feedback Method and Device
The method includes that: a first transmission node receives a signal including a Transmission Block (TB) from a second transmission node; the first transmission node obtains states of the P CB sets according to the signal including the TB; the first transmission node determines at least one kind of feedback information in a preset feedback information set according to the states of the P CB sets; and the first transmission node sends the determined feedback information to the second transmission node.
Method and apparatus for transmitting uplink control information in wireless communication system
Provided are a method and an apparatus for transmitting uplink control information (UCI), which is carried out by a terminal in a wireless communication system. If the number of information bits of the UCI falls inside a specific range when different types of UCI are transmitted through the same PUCCH format, a bit sequence of each of the UCI are channel-coded by aligning/interleaving, wherein the aligning/interleaving is carried out so that the UCI having high importance are channel-coded so as to have better decoding performance.
EFFICIENT SIGNALING OVER ACCESS CHANNEL
An apparatus and method for transmitting an indicator of channel quality while minimizing the use of a broadcast channel is described. A metric of forward link geometry of observed transmission signals is determined. An indicator of channel quality value is determined as a function of the observed transmission signals. An access sequence is selected, randomly, from one group of a plurality of groups of access sequences, wherein each of the plurality of groups of access sequences correspond to different ranges of channel quality values.
FEEDBACK INFORMATION PROCESSING METHOD, DEVICE AND SYSTEM
Provided are a method, apparatus and system for processing feedback information. The method includes, the first transmission node receiving a signal of a data shared channel, and determining data transmission level indication information of a transport block according to the signal; and the first transmission node transmitting the data transmission level indication information corresponding to the transport block to a second transmission node.
LOW LATENCY ACK/NACK TRANSMISSION
Some embodiments of the present disclosure provide a user equipment (UE) having active device components and passive device components. Responsive to receiving downlink (DL) transmissions in time division duplexing (TDD) mode, the active device components perform DL decoding while the passive device components perform passive transmission of ACK/NACK data. Such passive transmission may involve encoding the ACK/NACK data in an altered version of received radio frequency (RF) signals and using so-called backscatter communications to reflect the received RF signals, with alteration, using the same frequency resources used to receive the DL transmissions.
