Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.

Apparatus and method for inter-band pairing of carriers for time division duplex transmit- and receive-switching and its application to multiplexing of different transmission time

Aspects of the disclosure provide for a thin control channel structure that can be utilized to enable multiplexing of two or more data transmission formats. For example, a thin control channel may carry information that enables ongoing transmissions utilizing a first, relatively long transmission time interval (TTI) to be punctured, and during the punctured portion of the long TTI, a transmission utilizing a second, relatively short TTI may be inserted. This puncturing is enabled by virtue of a thin channel structure wherein a control channel can carry scheduling information, grants, etc., informing receiving devices of the puncturing that is occurring or will occur. Furthermore, the thin control channel can be utilized to carry other control information, not being limited to puncturing information. Other aspects, embodiments, and features are also claimed and described.

Apparatus and method for synchronous multiplexing and multiple access for different latency targets utilizing thin control

Aspects of the disclosure provide for a thin control channel structure that can be utilized for a variety of purposes including, for example, enabling the multiplexing of two or more data transmission formats. In another example, the thin control channel can be utilized to carry control information that relates to interference experienced by a user. By utilizing this control information on a thin control channel, the network can take suitable action to mitigate the interference. Other aspects, embodiments, and features are also claimed and described.

Apparatus and method for inter-band pairing of carriers for time division duplex transmit- and receive-switching and its application to multiplexing of different transmission time intervals

Aspects described herein relate to communicating feedback in wireless communications. A user equipment (UE) can receive, in a downlink portion of a slot, data communications from a base station, where the data communications comprise multiple code blocks received in one or more downlink symbols. The UE can generate one or more feedback bits to provide feedback for the multiple code blocks. The UE can transmit, to the base station and in an uplink portion of the slot, an indication of the one or more feedback bits.

Uplink multi-bits acknowledgement for self contained transmissions

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a bandwidth part configuration for a plurality of bandwidth parts, wherein a first bandwidth part of the plurality of bandwidth parts is identified as being activated and is associated with first resources allocated for uplink grant-free transmissions by the UE on the first bandwidth part. The UE may receive determine to deactivate the first bandwidth part and activate a second bandwidth part, and may determine to reactivate the first bandwidth part. The UE may identify second resources for uplink grant-free transmissions by the UE on the first bandwidth part based at least in part on the bandwidth part configuration. Numerous other aspects are provided.

Managing release of resources for uplink grant-free transmissions on bandwidth part deactivation

Aspects of the disclosure relate to determination of bandwidth, frequencies, or a set one or more of subbands that carries a downlink control channel. In some examples, a set of one or more subbands that carries a downlink control channel may be determined based on a function of a predetermined reference resource location. The predetermined reference resource location may be a set of one or more subbands that carries one or more synchronization signals and a broadcast channel. Other aspects, embodiments, and features are also claimed and described.

Control channel bandwidth determination

The disclosure relates in some aspects to multiplexing different types of traffic. Techniques are disclosed to facilitate puncturing one type of traffic with another type of traffic (e.g., traffic having more stringent latency and/or reliability requirements). In some aspects, these techniques mitigate potential loss of control information for the punctured traffic. In some aspects, the disclosed techniques are applicable to mobile broadband traffic and mission critical traffic.

Traffic multiplexing

The present disclosure provides techniques for performing bit-level interleaving for orthogonal frequency-divisional multiplexing (OFDM) symbols across a plurality of code blocks. In some aspects, a transmitting device may dynamically switch between bit-level interleaving and tone-level interleaving for each OFDM symbol based on factors such as number of bits that are carried in each tone, size of each code block, the processing time requirements of the transmitting device and/or the receiving device, or the transmitting device preference.
