Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines a first decoding candidate in a first search space and a second decoding candidate in a second search space, where the first decoding candidate and the second decoding candidate have a same size but different definitions of information fields, identifies a difference in the information fields, and determines one of the first decoding candidate and the second decoding candidate as a valid candidate based on the identified difference. The apparatus further generates first control information for transmitting in a first search space, codes the first control information, wherein the code applied to the first control information is specific to the first search space and different from code applied to second control information in a second search space, and transmits the coded first control information in the first search space.

Abstract: Various embodiments include multi-subscription multi-standby (MSMS) communication devices and methods for managing reception of data using a first subscription following a tune-away by a radio frequency (RF) resource chain from the first subscription to a second subscription. In various embodiments the MSMS communication device may receive data over the first subscription during a warm-up period of the RF resource chain following completion of the tune-away. In some embodiments, the device processor may receive the data over the first subscription during the warm-up period using one or more channel parameters of the first subscription determined before the tune-away. In some embodiments, the device processor may receive data over the first subscription during the warm-up period using one or more channel parameters of the first subscription determined initially during the warm-up period.

Abstract: Various embodiments enable a multi-active mobile communication device to mitigate (manage) interference by a frequency band used by a first subscription with the frequency band used by a second subscription. The device processor may generate modified power measurements for one or more frequency bands of a first subscription and use the modified power measurement(s) to cause the first subscription to switch from the frequency band that interferes with the frequency band of the second subscription. The modified power measurement may be a decreased power measurement of the first frequency band and/or an increased power measurement of a second frequency band that does not interfere with the frequency band of the second subscription. As a result, various embodiments may mitigate or otherwise manage the impact of coexistence interference between the first and second subscriptions of a multi-active mobile communication device without limiting capabilities of the device or changes to the network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first sounding reference signal (SRS) configuration, wherein the first SRS configuration indicates a number of antenna ports on which an SRS is to be transmitted. The UE may determine that the number of antenna ports indicated by the first SRS configuration exceeds an antenna capability of the UE. The UE may transmit one or more SRSs using a second SRS configuration based at least in part on determining that the first SRS configuration exceeds the antenna capability of the UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices are described for identifying and mitigating in-device coexistence interference for multicarrier systems implementing soft combining decoding techniques. In some aspects, the described techniques include identifying time-frequency resources of a received signal subject to coexistence interference at a transceiver of a wireless device. The time-frequency resources may include, for example, symbols, slots, code-blocks, sub-frames, subcarriers, etc. Resource-specific mitigation may then be applied to the identified resources, for example, including skipping or nulling the interfered resources in the time domain, frequency domain, or both. In some aspects, the resource-specific mitigation may be performed at the soft-combining stage of the decoding process, such as by skipping or nulling one or more log likelihood ratio (LLR) instances that correspond to the interfered resource(s).
