Information transmission method and apparatus

The present disclosure provides an information transmission method, including: generating first information; determining a first sequence from N candidate sequences based on the first information; and sending the first sequence. The first information belongs to N candidate information. A mapping between the first information and the first sequence belongs to P mappings. Each of the P mappings includes a mapping between the N candidate information and the N candidate sequences. The N candidate sequences are generated based on N dedicated cyclic shift values and a first initial cyclic shift value. In at least two mappings, dedicated cyclic shift values used to generate candidate sequences corresponding to a same candidate information are different, where the same candidate information belongs to L candidate information in the N candidate information, both P and L are integers greater than 1, and the L is less than or equal to N.

Vector signaling code with improved noise margin
11716227 · 2023-08-01 · ·

Methods are described allowing a vector signaling code to encode multi-level data without the significant alphabet size increase known to cause symbol dynamic range compression and thus increased noise susceptibility. By intentionally restricting the number of codewords used, good pin efficiency may be maintained along with improved system signal-to-noise ratio.

Transmission configuration indicator pool across multiple component carriers

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate with a base station using a beamforming configuration, according to a transmission configuration indicator (TCI) configuration. The UE may receive a message including a TCI configuration. The UE may determine based on the TCI configuration, a TCI pool for a TCI state type of a set of TCI state types and a set of CCs. The UE may then perform the wireless communication via a directional beam based on the TCI pool for the TCI state type and the set of component carriers (CCs).

System and method for HARQ feedback in RRC inactive state

Systems and methods for transmitting uplink control information, for example ACK/NACK, while in RRC_inactive state, are provided. Uplink control information is transmitted while in RRC_INACTIVE state by transmitting a sequence from a set of possible sequences to convey the uplink control information, the transmitted sequence associated with a value of the uplink control information. The sequence is asynchronously transmitted. Signalling may be used to configure a transmission resource within which to transmit the sequence, wherein the transmission resource has a time duration that is longer than a time duration to transmit the sequence. This has the effect of introducing a gap following sequence transmission that can ensure the sequence transmission does not interfere with a data transmission.

Broadcast signal transmission apparatus using transmission identifier and method using same

An apparatus for transmitting broadcasting signal using transmitter identification and method using the same are disclosed. An apparatus for transmitting broadcasting signal according to an embodiment of the present invention includes a waveform generator configured to generate a host broadcasting signal; a transmitter identification signal generator configured to generate a transmitter identification signal for identifying a transmitter; and a combiner configured to inject the transmitter identification signal into the host broadcasting signal in a time domain so that the transmitter identification signal is transmitted synchronously with the host broadcasting signal.

Method and apparatus for random access to radio services

A radio performs random access by receiving control information and grouping a predetermined number of sequences that are generated from a plurality of base sequences into a plurality of groups by partitioning the predetermined number of sequences. At least one of the groups is associated with a first respective range of data amounts and a first respective range of reception qualities. Sequences generated from a common base sequence are arranged in an increasing order of respective cyclic shifts associated with the sequences. A sequence is randomly selected from a plurality of sequences contained in one group of the plurality of groups. A position at which the predetermined number of sequences are partitioned is determined based on the control information. A number of sequences contained in each of the plurality of groups varies in accordance with the control information.
