摘要:
In embodiments, a base station may identify a parameter related to a zero power (ZP) resource element (RE) mapping set in a physical resource block (PRB). The ZP RE mapping set may relate to resources that are not to be used to transmit a physical channel transmission. The base station may then transmit, to a user equipment (UE), an indication of the ZP RE mapping set. Other embodiments may be described and/or claimed.
摘要:
Techniques for detecting puncturing of a first PDSCH (physical downlink shared channel) associated with a UE (user equipment) by a second PDSCH with a shorter TTI (transmission time interval) are discussed. A base station (e.g., Evolved NodeB or eNB) can configure the UE for potential puncturing and/or parameter(s) of the second PDSCH. The UE can detect puncturing of the first PDSCH based on the configuration, and can discard punctured symbols to mitigate interference from the second PDSCH.

Provided herein are method and apparatus for precoder determination and precoder matrix indicator (PMI) indication for uplink transmission. The disclosure provides an apparatus for a user equipment (UE), comprising circuitry configured to: determine a precoder for each of a plurality of precoder resource block groups (PRGs) for an uplink transmission, wherein the plurality of PRGs are configurable in at least one of PRG size and number; and precode each of the plurality of PRGs with a determined precoder; and a memory to store the determined precoder for each of the plurality of PRGs.

Described is an apparatus of an eNB operable to communicate with a UE on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, a third circuitry, and a fourth circuitry. The first circuitry may be operable to process a first transmission carrying a DM-RS antenna port group indicator and a second transmission carrying an antenna port configuration indicator. The second circuitry may be operable to select a DM-RS antenna port group comprising a set of antenna port configurations based upon the DM-RS antenna port group indicator. The third circuitry may be operable to select an antenna port configuration out of the set of antenna port configurations based upon the antenna port configuration indicator, the antenna port configuration comprising one or more DM-RS antenna ports. The fourth circuitry may be operable to process a third transmission carrying DM-RS in accordance with the selected configuration.

Described is an apparatus of a User Equipment (UE). The apparatus may comprise a circuitry operable to process a first set of Downlink (DL) symbols in accordance with a first numerology having a first subcarrier spacing, the first set of symbols carrying a reference signal. The circuitry may also be operable to process a second set of DL symbols in accordance with a second numerology having a second subcarrier spacing, the second set of symbols carrying a data channel.
