Abstract: Wireless communications systems and methods related to allocating resource blocks and resource block groups in a system band in order to reduce overhead associated with resource allocation. To reduce overhead, the wireless communication device communicates a signal in a control channel that indicates a general area and a resource block in the general area that stores data. The wireless communication device then communicates multiple resource blocks that include the resource block and communicates the data in the resource block using the signal. To reduce overhead, the wireless communication device also communicates multiple mappings for each resource block group into a set of resource blocks and a signal in a control channel that selects one of the multiple mappings. The communication device then determines resource blocks that are included in the resource block group according to the mapping, and communicates data in these resource blocks.

Abstract: In a process of beam change, the base station transmits a beam change instruction to a user equipment (UE) to indicate that the base station will change from a current beam to another beam, but the UE may not successfully receive the beam change instruction. The apparatus may be a base station that is configured to address such issues. The base station determines to change from a first beam to a second beam. The base station transmits, to a UE, a beam change instruction to indicate the determination to change to the second beam upon the determination to change to the second beam. The base station determines whether the UE has received the beam change instruction. The base station selects a third beam to communicate with the UE when the base station determines that the UE has not received the beam change instruction, wherein the third beam is a predefined beam.

Abstract: Systems and methods of wireless communication in which wireless devices are adapted to implement adaptive waveform selection are disclosed. For example, operation according to embodiments may provide for use of a waveform design that minimizes peak-to-average power ratio (PAPR), such as single-carrier frequency division multiplexing (SC-FDM), as well as a waveform design that provides higher spectral efficiency, such as orthogonal frequency division multiplexing (OFDM), for scenarios that are not power-limited and the higher PAPR is acceptable. Adaptive waveform selection may be based implicitly on one or more parameters or may be based on explicit signaling. Adaptive waveform selection may be utilized with respect to initially establishing a communication link and/or with respect to an established communication link.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may receive a first measurement report from a user equipment (UE) that includes an indication of a measurement parameter associated with a first beamformed reference signal. The base station may receive additional measurement reports from the UE for additional base stations. The additional measurement reports may include an indication of measurement parameters associated with additional beamformed reference signals transmitted by the additional base stations. The base station may identify a location of the UE based on the first measurement report and the additional measurement report. Alternatively, the UE may transmit multiple beamformed sounding reference signals to multiple base stations, and a single base station may identify a location of the UE based on multiple reports collected from the multiple base stations.

For example, the method may include configuring a 10 ms transmission mode on an uplink (UL) channel at the UE, indicating configuration of the 10 ms transmission mode to a base station in communication with the UE, compressing a 20 ms transmission associated with a 20 ms transmission time interval (TTI) into a 10 ms compressed transmission, transmitting the 10 ms compressed transmission during a first 10 ms of the 20 ms TTI, and performing a discontinuous transmission (DTX) of the UL channel during a second 10 ms of the 20 ms TTI. As such, reduced battery consumption at a UE may be achieved.

For example, a method of uplink mobile communication at a user equipment is presented, which may include compressing two consecutive voice packets having a first voice packet transmission time interval into two compressed voice packets having a second voice packet TTI. In addition, the method may include compressing signaling data corresponding to a first dedicated control channel (DCCH) TTI into compressed signaling data having a second DCCH TTI and multiplexing the two compressed voice packets and the compressed signaling data to form a multiplexed packet. Furthermore, the method may include splitting the multiplexed packet into a first and second subpacket, transmitting the first subpacket during a first subpacket interval having a subpacket TTI, and transmitting the second subpacket during a second subpacket interval subsequent to the first subpacket interval, wherein the second subpacket interval has the subpacket TTI.

Abstract: The disclosure provides for a compressed mode transmission gap in wireless communications. A user equipment (UE) may receiving a downlink dedicated physical channel (DPCH) having a slot-format and a spreading factor during a first compression interval. The downlink DPCH may not include a compressed-mode transmission gap during the first compression interval. The UE may receive the downlink DPCH having the same slot-format and the same spreading factor during a second compression interval. The UE may determine that the downlink DPCH includes a compressed-mode transmission gap during the second compression interval. A set of slots of the downlink DPCH during the transmission gap may be punctured. The UE may decode the downlink DPCH for the second compression interval based on a set of remaining slots received during the second compression interval. In an aspect, the UE may estimate a SIR based on a TPC command in a last slot of the transmission gap.

Abstract: Aspects of the present disclosure provide techniques for using automatic gain control symbols to indicate a sidelink mini-slot. A method performed by a transmitting user equipment includes transmitting, during a first time portion of a symbol within a slot, a first beam associated with a first receiving user equipment. The first time portion of the symbol is configured to indicate that the first receiving user equipment will receive another transmission from the transmitting user equipment during a first mini-slot within the slot associated with the first time portion. The method may further include transmitting, during a second time portion of the symbol within the slot, a second beam associated with a second receiving user equipment. The second time portion of the symbol is configured to indicate that the second receiving user equipment will receive another transmission from the transmitting user equipment during a second mini-slot within the slot.
