Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for downlink control information (DCI) communication and processing. One example method generally includes determining a limit, between a transmission time of a control channel carrying a DCI of a plurality of DCI and a time of an event enabled by the DCI, of a quantity of the plurality of DCI in a frame, generating a frame comprising the plurality of DCI in accordance with the determined limit, and transmitting the frame to a user-equipment (UE).

Abstract: The disclosure relates in some aspects to information encoding. Information encoding may involve puncturing bits of a codeword or repeating bits of a codeword. The disclosure relates in some aspects to selecting a puncturing or repetition pattern. In some aspects, a puncture pattern for data encoding is selected based on a criterion that the output and the repetition input of an XOR are not erased. In some aspects, a repetition pattern for data encoding is selected based on a criterion that repetition not be applied for the output and the repetition input of an XOR.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for rate-matching control channels using polar codes. An exemplary method generally includes encoding a stream of bits using a polar code, determining a size of a circular buffer for storing the encoded stream of bits based, at least in part, on a minimum supported code rate and a control information size, and performing rate-matching on stored encoded stream of bits based, at least in part, on a mother code size, N, and a number of coded bits for transmission, E.

Abstract: The disclosure relates to reduced signaling to carry out the linking between new radio (NR) carrier aggregation (CA) band combinations and NR band processing combinations (BPCs), and includes apparatus and methods of receiving, at a modem of a user equipment (UE), a UE configuration from a base station based on UE band combination constraint information, configuring the UE, by a processor of the UE, according to the UE configuration, and performing a communication with the base station, via the modem of the UE, according to the UE configuration. In an implementation, the disclosure includes transmitting the UE band combination constraint information, such as in the form of receiving a total number of layers supported in a CA band combination, and wherein receiving the UE configuration further comprises receiving a CA combination and a BPC configuration in response to the UE band combination constraint information.

Abstract: An apparatus and method of wireless communications includes transmitting, by a user equipment (UE), a mid-amble position indication and/or a UE capability information, wherein at least one of the mid-amble position indication or the UE capability information facilitate identification of a mid-amble position within a slot. Additionally, the aspects include receiving, by the UE, a transmission including a transmitted slot having a preamble and a mid-amble, wherein the mid-amble is at the mid-amble position within the slot as determined based at least in part on the at least one of the mid-amble position indication or the UE capability information. For example, the preamble and the mid-amble include pilot signals, such as Demodulation Reference Signals (DMRSs).

Abstract: A user equipment (UE) may improve scheduling of inter radio access technology (IRAT) measurement during continuous data transmission, for example in a High Speed-Physical Downlink Shared Channel (HS-PDSCH). The UE may determine whether an IRAT measurement is desired. The UE may also perform the IRAT measurement during a scheduled downlink data subframe when it is determined the IRAT measurement is desired, without losing the scheduled downlink data.
