Abstract: A method may include sending a contention resolution message for a random access procedure from a user equipment (UE) through a physical uplink channel in a wireless communication network, and sending a repetition of the contention resolution message from the UE through the physical uplink channel. The physical uplink channel may include a physical uplink shared channel (PUSCH). The method may further include selecting a preamble from a first preamble group corresponding to a capability of the UE to send the repetition of the contention resolution message, and sending the preamble from the UE. Selecting the preamble from the first preamble group may include selecting a preamble from a first preamble sub-group corresponding to the capability of the UE to send the repetition of the contention resolution message.

Abstract: Methods, systems, and devices for wireless communications are described for a relay UE and a source UE to provide transmissions of uplink communications in a decode and forward procedure in which redundancy version (RV) identifications of each instance of a transmission or retransmission are associated with a particular link of the source UE or relay UE. A set of RV sequences may be configured, with the source UE using a first subset of the RV sequences, and the relay UE using a second subset of RV sequences that is non-overlapping with the first subset. A base station or destination UE that receives the transmissions from the source UE and relay UE may thus receive RVs in accordance with the set of RV sequences.

Abstract: A method for data transmission and related products are provided. The method includes the following. A first application data packet of a first application is obtained during running the first application. The first application data packet is tagged according to first user identification (UID) of the first application, and a first data packet tag of the first application data packet is obtained. A target PLR of data transmitted by the Wi-Fi module is obtained in response to that the first data packet tag is identified by the Wi-Fi module. When the target PLR is greater than a first threshold, first maximum number of retransmissions of the first application data packet is increased to first target number of retransmissions according to the target PLR. The first application data packet is transmitted according to the first target number of retransmissions.

Abstract: Methods and apparatuses for transmission of k repetitions over a channel are described. Repetition formats for the transmissions include options for slot-based repetition, mini-slot based repetition, intra-slot frequency hopping, inter-slot frequency hopping, data splitting, data switching, and DMRS sharing, among others. In some examples, intra-slot frequency hopping is performed. A first repetition of the k repetitions is sent over the channel, starting from a first symbol within a first slot, and using a first set of frequency resources. A second repetition of the k repetitions is sent over the channel, following the first repetition and starting from a second symbol within the first slot, and using a second set of frequency resources.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for increasing the chances that a high reliability packet scheduled to be transmitted in a shared radio frequency spectrum is received by a receiving device. In one example, a wireless device (e.g., a base station or a user equipment (UE)) may duplicate a packet at a packet data convergence protocol (PDCP) layer for transmission on multiple listen before talk (LBT) subchannels of a carrier to improve reliability. In another example, a wireless device may duplicate a packet at a physical (PHY) layer for transmission on multiple LBT subchannels of a carrier to improve reliability, or the wireless device may encode and map the packet to multiple LBT subchannels of a carrier for transmission on the multiple LBT subchannels to improve reliability.

Abstract: In the present invention, a common UL control channel resources is configured and scheduled for sharing among URLLC UEs (102) within a servicing cell. An enhanced HARQ-less transmission technique (20) is employed for delivering DL URLLC data packets to the intended UEs (102). On DL URLLC data transmission basis, via a scheduling DCI, a gNB (101) dynamically indicates to the intended URLLC UE (102), the UL control resource including the time slots for use in transmitting limited acknowledge information.

Abstract: Certain aspects of the present disclosure provide techniques for cross-carrier repetition. A method that may be performed by a user equipment (UE) includes monitoring for an initial transmission of data from a network on a first entity, receiving control information indicating second entities for receiving retransmission repetitions of the data, and receiving the retransmission repetitions of the data via the second entities.

Abstract: A disclosure of the present specification provides a method for performing a random access procedure for coverage enhancement. The method may comprise the steps of: transmitting a random access preamble repetitively to a certain cell on the basis of a predetermined repetition level; when a random access response has not received within a random access response window, reconfiguring the repetition level; and retransmitting the random access preamble repetitively on the basis of the reconfigured repetition level.

Abstract: A configurable apparatus includes a housing, a cradle, and a handset. In a first configuration, a first bracket is releasably attached to the cradle and to the housing such that the cradle is disposed next to a first side of the housing. In a second configuration, a second bracket is releasably attached to the cradle and to the housing such that the cradle is disposed next to a second side of the housing. The first and second brackets can include L-shaped brackets, which can be mirror images of each other. The communication system may be used in multi-story buildings or similar structures to facilitate communications among multiple stations (e.g., emergency response stations) within the structures.
