Abstract: The present disclosure relates to a method used in a User Equipment (UE) for reporting Hybrid Automatic Repeat Request (HARQ) acknowledgement (ACK)/non-acknowledgement (NACK) for Physical Downlink Shared Channels (PDSCHs) in dynamic time division duplex (TDD) configurations. In the method, a plurality of PDSCHs are received in DownLink (DL) subframes associated with an UpLink (UL) subframe and indicated by a DL reference TDD configuration. The DL subframes are divided into a first subset of DL subframes and a second subset of DL subframes. The first subset of DL subframes is also indicated by an UL reference TDD configuration. A first set of Physical Uplink Control Channel (PUCCH) resource indices are assigned based on resources used in transmission of Physical Downlink Control Channels (PDCCHs) corresponding to the PDSCHs received in the DL subframes of the first subset of DL subframes. A second set of PUCCH resource indices are assigned based on resources used in transmission of PDCCHs corresponding to the PDSCHs received in the DL subframes of the second subset of DL subframes. For each of the received PDSCHs, HARQ ACK/NACK is reported by using PUCCH resources in an order of the assigned first set of PUCCH resource indices for PDSCHs received in the DL subframes of the first subset of DL subframes and in an order of the assigned second set of PUCCH resource indices for PDSCHs received in the DL subframes of the second subset of DL subframes. The present disclosure also relates to a UE and BS for respectively reporting and receiving HARQ ACK/NACK for PDSCHs in TDD configuration.

Abstract: A repeater control method includes determining, by a repeater, a target state based on a terminal access status and/or first information indicated by a network-side device; and performing, by the repeater, state switching based on the target state. The target state includes a first state or a second state, the first state indicates that the repeater amplifies and/or forwards an input signal, and the second state indicates that the repeater does not amplify and/or forward an input signal.

Abstract: A wireless communications method and system, a network device, and user equipment. The method includes: sending, by a network device, resource configuration information to user equipment, where the resource configuration information is used to indicate a first transmission resource corresponding to first transmission, and duration of a transmission resource occupied by one transmission of the first transmission is less than 1 millisecond; and communicating, by the network device, with the user equipment based on the first transmission resource. In this way, a transmission delay can be shortened, user experience can be greatly improved, and performance of a wireless network can be greatly enhanced.

Abstract: Various embodiments provide techniques for channel state information reference signal (CSI-RS) transmission in a wireless cellular network. CSI-RS transmission bandwidth is determined based on a frequency domain allocation of a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), or a physical downlink control channel (PDCCH). A user equipment (UE) receives the CSI-RS according to the frequency domain allocation and a time domain allocation.

Abstract: To enable full-duplex communication in a time division duplexing (TDD) band, a network node (e.g., a user equipment (UE)) may be configured to communicate in one or more flexible bandwidth parts (BWPs) using BWP-specific TDD patterns regardless of a TDD pattern configured for the underlying band. However, in some cases, half-duplex communication may offer better performance than full-duplex communication (e.g., when full-duplex communication may cause self-interference or there is a need for high throughput half-duplex communication). Accordingly, some aspects described herein relate to timing considerations and switching indications for indicating an interval in which the network node is to operate in the flexible BWP using the BWP-specific TDD pattern and switching between the BWP-specific TDD pattern and the TDD pattern of the underlying band (e.g., using switching indications based on a number or quantity of transmission time intervals and/or a timer, among other examples).

Abstract: Time-division duplexing (TDD) detection in wireless distributed communications systems (DCSs) to synchronize TDD downlink and uplink communications. Remote units in the wireless DCS include an adaptive TDD communications synchronization circuit that includes a power detection circuit configured to detect TDD communications signals distinguished from noise. The power detection circuit is configured to adaptively set a noise threshold floor level for TDD downlink communications link by detecting the noise level on the TDD downlink communications link that includes a TDD uplink communication period. The adaptive TDD communications synchronization circuit can also include a symbol edge detection circuit configured to generate an edge trigger signal indicating the symbol edges of TDD downlink communication signals. The symbol edge trigger is used by a TDD frame configuration build circuit to generate a TDD communications frame configuration to control switching of the downlink and uplink communications circuits for synchronizing TDD downlink and uplink communications.

Abstract: This disclosure describes techniques that enable a carrier aggregation of two or more carrier available carriers for uplink transmissions at a base station node. More specifically, a carrier aggregation controller may receive a resource allocation request from a base station node that is associated with an uplink transmission of user plane data from a client device. The carrier aggregation controller may determine a carrier aggregation for the uplink transmission and generate scheduling information for delivery to the base station node that is based at least in part on the carrier aggregation.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support resource restrictions for sub-band full duplex (SBFD) and dynamic time division duplex (TDD) operations. For example, a user equipment (UE) may receive, from a network entity, control signaling indicating a restriction to one or more slots associated with communications between the UE and the network entity. Each of the one or more slots may be associated with one or more sub-bands and the restriction may modify an availability of a duplexing setting for at least a portion of the one or more sub-bands. Additionally, the UE may communicate with the network entity via at least a subset of the one or more sub-bands of the one or more slots in accordance with the restriction.
