With advanced compute capabilities and growing convergence of wireless standards, it is desirable to run multiple wireless standards, e.g., 4G, 5G NR, and Wi-Fi, on a single signal processing system, e.g., a system on a chip (SoC). Such an implementation may require simultaneously receiving and transmitting signals corresponding to each wireless standard and also signal processing according to respective requirements. Typical solutions involve providing separate hardware blocks specific to each wireless standard, which in turn requires more area on the SoC and consumes more power. Embodiments of the present disclosure provide a unified hardware that may process signals across different standards in both a transmitting direction and a receiving direction simultaneously.

Wireless communications are described. Reduced transmission power time intervals may be employed in communications via one or more cells. A wireless device may receive an indication of measurement resources for one or more cells. The wireless device may transmit channel state information for one or more of the cells. Cross carrier scheduling may be employed.

A multiple access method, a multiple access transmitter, and a multiple access receiver includes performing, by a transmitter, channel coding on a bit sequence to determine a coded sequence. The method also includes interleaving and/or scrambling the coded sequence, and performing multidimensional constellation modulation on the interleaved and/or scrambled sequence; performing grid mapping on the modulated symbol sequence to determine a mapped sequence, and transmitting the mapped sequence. The method also includes receiving, by a receiver, mixed signals from multiple transmitters, the mixed signals are obtained by performing, by each of the multiple transmitters, interleaving and/or scrambling, multidimensional constellation modulation and grid mapping on data. The method further includes decoding, by the receiver, mixed information according to interleaver information and/or scrambler information, multidimensional constellation information and grid mapping pattern information corresponding to each transmitter to obtain data corresponding to each transmitter.

This application provides a communication method, including: receiving, by a terminal device, configuration information, where the configuration information is used to configure M component carriers, and M is a positive integer; determining, by the terminal device, N types of DCI sizes based on the configuration information; and if N is greater than a first threshold, determining, by the terminal device, Q types of DCI sizes, and detecting a downlink control channel in a first time unit based on the Q types of DCI sizes, where Q is less than or equal to the first threshold. According to the communication method provided in this application, a capability of detecting a DCI size by a terminal device can be fully used.

In a distribution shaping method, information compression and distribution shaping are executed at the same time. A symbol sequence of a predetermined length is allocated to an input bit sequence of a predetermined length on a one-to-one basis. In the allocation, a bit sequence smaller in entropy is allocated a symbol sequence smaller in average power.

Proposed are a method and an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a receiving STA receives a PPDU from a transmitting STA via broadband communication and decodes the PPDU. The PPDU is received on the basis of an OFDMA scheme. The PPDU includes a first signal field. The first signal field includes first information on a preamble puncturing pattern for each 80 MHz band in the broadband communication. The first information consists of a 4-bit bitmap for the 80 MHz band.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first hybrid automatic repeat request acknowledgement (HARQ-ACK) payload for a first component carrier (CC) set based at least in part on a first downlink assignment index (DAI). The UE may determine a second HARQ-ACK payload for a second CC set based at least in part on a second DAI. The UE may transmit the first HARQ-ACK payload for the first CC set and the second HARQ-ACK payload for the second CC set. Numerous other aspects are provided.

A profile optimizing method is provided for a downstream channel transmission of active subcarriers to user devices. The method includes steps of receiving channel measurement data from each user device for each subcarrier, calculating a maximum bit-loading value for each user device per subcarrier, grouping the user devices into a plurality of clusters based on a proximity of the maximum bit-loading values of a first user device to those of a second user device within the particular cluster, assigning each user device within the particular cluster to a single cluster profile. A plurality of single cluster profiles for the plurality of clusters forms a set of cluster profiles. The method further includes steps of determining a channel capacity ratio for the set of cluster profiles, and combining at least two single profiles of the set of cluster profiles into a coalesced profile pair.

Wireless communications systems and methods related to communicating uplink control information (UCI) in a network operating over multiple aggregated unlicensed carriers are provided. A first wireless communication device communicates, with a second wireless communication device, a downlink communication signal. The first wireless communication device communicates, with the second wireless communication device, an unscheduled uplink communication signal including an uplink report associated with the downlink communication signal, the unscheduled uplink communication signal communicated based on a listen-before-talk (LBT) procedure. The uplink report includes at least one of an acknowledgement (ACK) for data in the downlink communication signal, a negative-acknowledgement (NACK) for the data in the downlink communication signal, or channel information based at least on the downlink communication signal.

A method for configuring downlink control information includes configuring by a base station a uplink scheduling downlink control information (DCI) and a downlink scheduling DCI of multi-Transmission Block (TB) transmission to have the same number of bits. A method for receiving downlink control information includes based on a preset blind detection bit number, performing, by a user equipment (UE), blind detection on an uplink scheduling Downlink Control Information (DCI) and a downlink scheduling DCI of multi-Transmission Block (TB) transmission, where the uplink scheduling DCI and the downlink scheduling DCI have the same number of bits.
