Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a base station, before a next paging occasion (PO) of a paging cycle, a page indication (PI) in a first PI location associated with the next PO, wherein the PI comprises at least one repetition of a plurality of repetitions of the PI transmitted in the first PI location on each of a plurality of beams, and decodes the PI to determine whether or not the UE is paged in the next PO.

Abstract: Wireless communications systems and methods related to resource partitioning for sidelink are provided. A first user equipment (UE) transmits, to a second UE, a time-division duplexing (TDD) configuration indicating a first set of resources time-multiplexed with a second set of resources in a sidelink resource pool, wherein the first set of resources is associated with a first link, and wherein the second set of resources is associated with a second link different from the first link. The first UE receives from the second UE over the first link, a first communication signal in a resource of the first set of resources. The first UE transmits, to the second UE over the second link, a second communication signal using a resource of the second set of resources.

Abstract: Wireless communications systems and methods related to reverse link operations in sidelink communications are provided. A first user equipment (UE) receive, from a second UE, sidelink resource pool information. The first UE may select, based on the sidelink resource pool information, a first resource from a set of resources in a sidelink resource pool, and transmit, to the second UE based on the sidelink resource pool information, a first sidelink transmission using the first resource.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a downlink configuration including a set of resources for receiving downlink transmissions. The UE may determine a grant for performing uplink transmissions based on a radio resource control (RRC) message. The UE may determine, based on the downlink configuration, the grant, or both, an uplink configuration including a set of resources for transmitting the uplink transmissions at a set of uplink transmission occasions. In some aspects, the set of uplink transmission occasions may be arranged according to a non-uniform spacing pattern in a time domain. The UE may transmit, to a base station, one or more uplink transmissions based on the uplink configuration.

Abstract: The present disclosure relates to methods and devices for communicating based on improved signaling. A base station can transmit an indication of resources in time and frequency to a UE allocated for NOMA communication with the UE. The indication of resources can comprise a set of NA-RUs. The UE can then transmit uplink NOMA communication to the base station based on the indication of resources received from the base station. Also, the base station can transmit a compact UL resource grant via DCI, or signal the semi-static transport format configuration via RRC, to the UEs allocated for NOMA communication. The DCI or the payload of RRC signaling can be scrambled with a NOMA group RNTI, as well as comprise NOMA transmission parameters indicated by a MCS table. The UE can then transmit uplink NOMA communication to the base station based on the DCI or the RRC signaling.

Abstract: Methods, systems, and devices for wireless communications are described. An example of a method in accordance with the present disclosure may include a UE identifying that the UE is configured to use a contention-based or uncoordinated (e.g., two-step) random access procedure including an uplink message and a downlink response, where the uplink message includes at least a preamble portion and a data portion. The UE may map an identifier of the UE into a block of source symbols, generate a codeword including a block of coded symbols from the block of source symbols, and generate a set of sequences, where each sequence is based at least in part on a value associated with a corresponding coded symbol of the block of coded symbols. The UE may transmit the generated set of sequences in a preamble portion of the uplink message.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may receive a downlink control information (DCI) message including an indication to enable discontinuous monitoring of a physical downlink control channel (PDCCH). The UE may enable the discontinuous monitoring of the PDCCH based on the received DCI message, and disable monitoring of the PDCCH during a temporal period in which at least one of physical downlink shared channel (PDSCH) reception, downlink reference signal monitoring, uplink reference signal transmissions, and channel reporting is enabled. The UE may thereby experience power saving by disabling monitoring of the PDCCH while still performing other wireless operations during the temporal period. The UE may, as a result, also include features for improvements to wireless communications and, in some examples, may promote high reliability and low latency wireless communications, among other benefits.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may determine to change a first slot format used when operating in a half-duplex mode based on a traffic pattern or a channel quality, or both, and may transmit a request to change the slot format to a base station. The request may include information relating to a slot format based on the traffic pattern or the channel quality, or both, such as an explicit indication of a slot format or a request for a different resource distribution between uplink symbols, downlink symbols, or flexible symbols, or any combination thereof. The base station may receive the request to change the slot format and may transmit an indication of a second slot format to the UE based on the request. The base station and the UE may communicate using the second slot format.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to determine a priority indicator for an upcoming transmission between the UE and a base station and transmit the priority indicator to the base station. The base station may receive the priority indicator, determine a network condition, and may transmit control information for a downlink transmission. The control information may include an indication of a set of modulation and coding schemes to select from a plurality of sets of modulation and coding schemes and an index value for an entry in the selected set of modulation and coding scheme, where the indication is based on the priority indicator and a network condition. The UE may identify a combination of a modulation order and a code rate for the downlink transmission based on the indication of modulation and coding scheme table and the index value.

Abstract: Aspects of the present disclosure provide techniques for design of channel raster for narrowband operation. One example method, performed by a base station, generally includes determining, based on one or more conditions, an exact frequency location of one channel of one or more channels to perform narrowband communications with a user equipment. The method also includes transmitting an indication of the one or more conditions to the user equipment. The method further includes communicating with the UE, based at least in part on the exact frequency location of the one channel.
