Embodiment 1

[0030] This embodiment provides a method for sending an uplink reference signal, which is applied to the base station side, such as figure 1 shown, including:

[0031] Step 110, the base station determines the resources used by the terminal to send the uplink reference signals of M ports or layers, M=8 or 16;

[0032] In this embodiment, the uplink reference signal includes at least one of the following: a measurement / sounding reference signal, an uplink demodulation reference signal, and an uplink phase compensation reference signal.

[0033] In this embodiment, the resources include time domain resources, frequency domain resources, and code domain resources; the uplink reference signals of the M ports or layers perform orthogonal multiplexing of resources, and the uplink reference signals of different ports or layers use At least one of the time domain resource, the frequency domain resource and the code domain resource is different.

[0034] In this embodiment, the base ...

Embodiment 2

[0121] This embodiment provides a method for receiving and processing an uplink reference signal, such as image 3 shown, including:

[0122] Step 210, the terminal receives high-level signaling or downlink control signaling sent by the base station, the high-level signaling or downlink control signaling includes indication information of resources used by the terminal to send uplink reference signals of M ports or layers, M = 8 or 16;

[0123] In this embodiment, the indication information includes partial configuration information of the resource; according to the indication information, the terminal determines the resources used for sending the uplink reference signals of the M ports or layers, including: the terminal Obtaining partial configuration information of the resources according to the indication information, and determining resources used for sending the uplink reference signals of the M ports or layers in combination with other configuration information of the r...

Embodiment 3

[0211] In this embodiment, the number of ports or layers configured by the base station for the terminal in high-level signaling or downlink control signaling (if the terminal performs precoding, it is called a layer, and if it does not perform precoding, it is called a port) is 8, which is The number of sending combs configured by the terminal is 2. In addition, the minimum number of RBs occupied by the uplink reference signal is 4 (the configuration information is agreed by both the base station and the terminal), and the number of available cyclic shift indexes is 8. In this embodiment, each resource block in the system has 12 subcarriers, and 4 resource blocks have a total of 48 subcarriers. When dividing by the number of sending combs is 2, the minimum length of the reference signal sequence is 48 / 2=24. The minimum length of the reference signal sequence is an integer multiple of the number of cyclic shifts, so the number of cyclic shifts of the sequence can be 6, 8, 12, ...

Abstract

The invention discloses an uplink reference signal sending method and device, an uplink reference signal receiving processing method and device, a base station and a terminal. The base station determines a resource employed by the terminal for sending uplink reference signals on M ports or layers, wherein the M is equal to 8 or 16. The base station generates a high layer signal or a downlink control signal and sends the signal to the terminal, wherein the high layer signal or the downlink control signal comprises indication information of the resource. The terminal receives the high layer signal or the downlink control signal sent by the base station, wherein the high layer signal or the downlink control signal comprises the indication information of the resource employed by the terminal for sending the uplink reference signals on the M ports or layers, and the M is equal to 8 or 16. The terminal determines the resource employed for sending the uplink reference signals on the M ports or layers according to the indication information. According to the methods, the devices, the base station and the terminal, the problem that in related technologies, the technical scheme for sending the uplink reference signals is incomplete is solved, and the 8-port or 16-port SRS (Sounding Reference Signal) resource multiplexing can be realized.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a method and device for sending and receiving an uplink reference signal, a base station, and a terminal. Background technique [0002] In related technologies, in Long Term Evolution (LTE for short), a Physical Downlink Control Channel (PDCCH for short) is used to carry uplink and downlink scheduling information and uplink power control information. Downlink Control Information (DCI for short) format (format) is divided into DCI format 0, 1, 1A, 1B, 1C, 1D, 2, 2A, 3, 3A, etc., and later evolved to LTE-A Release 12 ( In LTE-A version 12), DCI formats 2B, 2C, and 2D are added to support a variety of different applications and transmission modes. The base station (e-Node-B, referred to as eNB) can configure the terminal equipment (User Equipment, referred to as UE) through downlink control information, or the terminal equipment accepts the configuration of higher layers ...
