    Abstract: Embodiments of this application provide a signal sending method, a signal receiving method, and an apparatus, to resolve a problem that channel estimation performance is affected. A reference signal is sent on one or more consecutive symbols, and modulation data is sent on an adjacent symbol previous to the one or more consecutive symbols in time domain and an adjacent symbol next to the one or more consecutive symbols in time domain. A sum of the modulation data carried in the symbol previous to the one or more consecutive symbols and the modulation data carried in the symbol next to the one or more consecutive symbols is zero or the modulation data is the same. Therefore, after time-domain filtering, the reference signal is not interfered with by the adjacent modulation data, so that channel estimation performance can be ensured.

    Abstract: A method for determining time information is disclosed. The method includes: obtaining, by a network node, information sent by a terminal device; and determining, by the network node, at least one of the following based on the information: a first time interval between downlink scheduling and downlink data transmission, a second time interval between the downlink data transmission and a feedback message sent by the terminal device after the terminal device receives downlink data, and a third time interval between uplink scheduling and uplink data transmission, where the information may include at least one of a subcarrier spacing, an operating band, and a bandwidth that are supported by the terminal device, and further include a first smallest value and/or a second smallest value and/or a third smallest value corresponding to the at least one item. Therefore, flexibility and accuracy of determining the time information are improved.

    Abstract: Embodiments of this application provide a communication processing method for a resource request and a related device. In the communication processing method, a terminal side device sends K uplink resource requests on K (K is an integer greater than or equal to 2) uplink channel resources in a transmission time unit (for example, 1 millisecond) to request an uplink resource used for uplink transmission, where cyclic shifts of a code division multiplexing (CDM) sequence used to send the K uplink resource requests on the K uplink channel resources are specific to the terminal side device, or a value of K is specific to the terminal side device, or a combination of the cyclic shifts and K is specific to the terminal side device.

    Abstract: A resource indication method, a device, and a system relate to the field of communications technologies. The method includes: allocating, by a base station, a BP to a terminal device, and sending, to the terminal device, a first message indicating a resource position of the BP; and receiving, by the terminal device, the first message sent by the base station, and then determining the resource position of the BP based on resource position information of at least one sub-BP, where the BP includes the at least one sub-BP, the BP is not greater than a maximum bandwidth supported by the terminal device, and the first message includes the resource position information of the at least one sub-BP. The BP is allocated by using a sub-BP as a granularity, so that signaling overheads can be reduced while a requirement for more flexible resource allocation is satisfied.

    Abstract: Various embodiments provide a signal transmission method and apparatus, and is applied to a multi-band communications system. Under the method, a terminal reports bandwidth capability information of a first frequency band in a plurality of frequency bands to a radio access network node. An operating band of the terminal includes the first frequency band, the bandwidth capability information of the first frequency band indicates a bandwidth capability of the terminal in the first frequency band, the bandwidth capability in the first frequency band is not less than a first threshold, and the first threshold is determined based on a maximum bandwidth capability of the terminal, the first frequency band, or a subcarrier spacing of the first frequency band. The terminal can send or receive a signal on a resource allocated by the radio access network node based on the bandwidth capability information.

    Abstract: The present disclosure provides example channel parameter estimation methods and related apparatuses. In one example method, a cable modem (CM) obtains a second data frame through a downlink channel between the CM and a cable modem termination system (CMTS). The second data frame is generated after a first data frame sent by the CMTS is modulated through the downlink channel, a zero-bit-loaded symbol of the first data frame includes no valid codeword, but includes a zero-bit-loaded NCP and an idle codeword identified by the zero-bit-loaded NCP, and the idle codeword includes a data sequence used for channel parameter estimation. The CM can estimate a channel parameter of the downlink channel based on a data sequence in an obtained zero-bit-loaded symbol of the second data frame and the data sequence in the zero-bit-loaded symbol of the first data frame.
