Embodiments of the disclosure provide a method for scheduling shared physical resource blocks (PRBs) by a user equipment (UE) in a wireless network and minimizing/reducing contention on the shared PRBs. The method includes: receiving PRBs from a network device, where the PRBs are shared among multiple UEs in the wireless network; detecting data at the UE for transmission; determining a modulation and coding scheme (MCS), a number of PRBs, and a size of a transport block required for data transmission in response to detecting the data; self-scheduling the shared PRBs based on at least one of the determined MCS, the number of PRBs, and the size of the transport block; and sending the data based on the self-scheduling along with self-scheduling information to the network device.

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.

In certain embodiments, encoding, symbol mapping, interleaving, and use of unique periodic identifiers function to enable a series of packets that may be received in a blockage impaired channel with reduced errors.

Embodiments of the present disclosure are directed to link adaptation, such as for physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH), in cases where channel state information (CSI) is available, as well as in cases where CSI is unavailable. Other embodiments may be disclosed and/or claimed.

The present invention relates to a method for transmitting and receiving channel quality information in a wireless communication system for supporting a Narrowband Internet of Things (NB-IoT) and a device therefor and, more particularly, the method comprising: transmitting and receiving a random access preamble; transmitting and receiving a random access response on the basis of the random access preamble; and transmitting and receiving channel quality information via a narrowband physical uplink shared channel (NPUSCH) on the basis of the random access response, wherein when the random access preamble is transmitted and received on the basis of a narrowband physical downlink control channel (NPDCCH) order in a radio resource control (RRC) connected state, the channel quality information is measured on the basis of a UE-specific search space (USS) set in the RRC connected state.

An apparatus for wireless communication based on sidelink accumulates a value, e.g., a token value, based on an accumulation rate of a transmit beam. When the apparatus has a packet for transmission over sidelink, the apparatus determines whether to transmit the packet over the sidelink based on a current accumulation of the value. The accumulation may be based on any of a CBR, a CR, and/or a feedback rate. A base station may measure interference on an access link of the base station and transmit a side link parameter that controls accumulation of a value at a transmitting device for the transmission of sidelink communication based on the measured interference.

A method is disclosed for enhancing downlink link adaptation (DLLA) for spectral efficiency maximization, comprising: providing an outer loop link adaptation (OLLA) routine with a first path for a first transmission mode and a second path for a second transmission mode; modifying, upon receiving a retransmit message for a first transmission with the first transmission mode, a first offset coefficient; modifying, upon receiving a second retransmit message for a second transmission with the second transmission mode, a second offset coefficient; and calculating a modulation and coding scheme (MCS) offset for the first transmission based on the first offset coefficient.

This application discloses an information sending method, an information receiving method, and a communication device and belongs to the field of wireless communication technologies. The information sending method includes: performing OVXDM or FTN waveform encoding on data, and generating and sending encoded information, where the encoded information is generated and/or sent based on a signal parameter; receiving feedback information sent by a receive end of the encoded information; and adjusting the signal parameter according to the feedback information.

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a base station transmitting a modulation and coding scheme index corresponding to a modulation and coding scheme table to a user equipment (UE). The modulation and coding scheme index may be applied to encoding or decoding a transport block. The modulation and coding scheme may be associated with at least two modulation orders or a differential indication according to a modulation and coding scheme table. To determine which of the modulation orders for processing the transport block, the UE and the base station may use a prior modulation order associated with a prior transmission of the transport block. The UE may process the transport block by encoding or decoding the transport block based at least in part on the determined modulation order.
