Systems, devices, and techniques are described for performing paging in a wireless communication network. A method includes mapping a paging indication to one or more resource elements. The one or more resource elements are resources in one or more synchronization signal symbols that are not mapped by the synchronization signal. The method includes transmitting the paging indication to trigger a response from a user equipment for performing subsequent paging.

This disclosure relates to techniques for supporting narrowband device-to-device wireless communication, including possible techniques for providing synchronization sequences. A first wireless device may transmit a preamble of a device-to-device wireless communication with a second wireless device. The preamble may include a first synchronization sequence. The first synchronization sequence may include multiple repetitions of a basis sequence, multiplied by a cover code. The basis sequence may span multiple orthogonal frequency division multiplexing symbols.

In a system, apparatus, method, and non-transitory computer readable medium for implementing fallback to conditional handover using a SSB reference signal, a UE device may be caused to, receive RRC reconfiguration information from a source RAN node, the RRC reconfiguration information including a SSB RS based CHO execution condition associated with at least one target cell controlled by a target RAN node, and a CSI-RS based CHO execution condition associated with the target cell(s), perform signal measurements of at least one SSB RS and at least one CSI-RS associated with the target cell(s), the at least one CSI-RS associated with a contention-free random access resource, and perform the CHO with the target cell(s) based on the signal measurement results of the at least one SSB RS, the at least one CSI-RS, the SSB based CHO execution condition, and the CSI-RS based CHO execution condition.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive a control message including a field for a timing offset, wherein the timing offset is applicable to a subset of a set of random access channel occasions. The network node may transmit a random access channel preamble in a time resource corresponding to the timing offset and associated with a random access channel occasion of the set of random access channel occasions. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive a system information message from a base station indicating a beam sweeping procedure supported by the base station. Based on the system information message, the UE may receive, as part of the indicated beam sweeping procedure, a first synchronization signal block (SSB) as part of first set of SSBs, and a second SSB as part of a second set of SSBs. The UE may then transmit, to the base station, one or more messages that indicate a narrow beam for communications between the UE and the base station. In some cases, the indicated beam may correspond to the first SSB and the second SSB, and is indicated on one or more random access channel (RACH) occasions associated with the beam sweeping procedure.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for dynamically reducing an aperture size to reduce overhead. In some implementations, a server can receive a first transmission from a first terminal through a communication network. The server can determine a timing offset associated with the first terminal based on the first transmission. The server can determine an aperture window size for an aperture window for the first terminal based on the determined timing offset associated with the first terminal. The server can generate allocation data that assigns communication resources to one or more terminals that includes the first terminal, the allocation data being based on the determined aperture window size for the first terminal. The server can communicate with the one or more terminals to indicate the communication resources respectively allocated to the one or more terminals.

Technology for an eNodeB to communicate with a user equipment (UE) using a self-contained time division duplex (TDD) subframe within a wireless communication network is disclosed. The eNodeB can process, for transmission to the UE, a DL self-contained time division duplex (TDD) subframe comprising an extended physical downlink shared channel (xPDSCH), an extended physical downlink control channel (xPDCCH), a downlink (DL) spacing signal, and a guard period, wherein the xPDSCH, the xPDCCH, the DL spacing signal, and the guard time are located within the DL self-contained TDD subframe prior to an extended physical uplink control channel (xPUCCH). The eNodeB can process, an uplink (UL) self-contained TDD subframe, received from the UE, having a UL spacing signal located after an extended physical uplink shared channel (xPUSCH).

Apparatuses, methods, and systems are disclosed for control information for a digitally controlled surface having reflective elements. One method (1300) includes transmitting (1302), from a first network device, a synchronization signal based on a control frame structure to a second network device including a digitally controlled surface having reflective elements. The method (1300) includes transmitting (1304) control information based on the control frame structure to a controller of the second network device. The control information is transmitted at least partly using a dedicated physical control channel, a sequence, and/or an on-off pattern.

The present specification provides a method for performing measurement by using an RSS in a wireless communication system. More specifically, the method performed by a terminal comprises the steps of: receiving, from a first base station, power boosting information indicating a relative value compared to cell-specific reference signal (CRS) power and CRS port information indicating the number of CRS antenna ports; receiving the RSS from the first base station; and measuring the reference signal received power (RSRP) and/or the reference signal received quality (RSRQ) of the RSS on the basis of the power boosting information and the CRS port information.

Methods, systems, and devices for wireless communications are described. In some examples, a random access occasion may overlap in time with a synchronization signal block resource, where the random access occasion and the synchronization signal block resource have a same index. In some such examples, a base station may transmit, to a user equipment (UE), an indicator of a mapping of the random access occasion to an uplink beam that is associated with a synchronization signal block resource with a different index than the random access occasion. The UE may transmit, to the base station, a random access preamble over the random access occasion using the uplink beam.
