Problems solved by technology

Therefore, the effective coverage of the coordinated cells is reduced, and the interference between the coordinated cells is strengthened
[0003] Moreover, although the shared physical resources corresponding to the physical uplink shared channel can be allocated cooperatively by coordinated cells, in the case of frequency modulation or scrambling technology, the coordinated allocation of shared physical resources by coordinated cells cannot be performed, resulting in conflicts in shared physical resources

example 1

[0056] Example 1: Uniform allocation

[0057] Scenario 1: CoMP11 selects one of the resource groups, for example: resource group 1, and the cooperating cell in CoMP11 allocates a certain resource in the resource group 1 for UEs (UE1, UE2) in CoMP mode. For example: resource group 1 includes resource a and resource b, and Cell1 allocates resource a in resource group 1 to UE1, then when Cell2 allocates resources to UE2, it will not allocate resource a, but can only allocate resource b. The resource group selected by CoMP11 may be specifically: the primary cell, the serving cell configured by the system, or the serving cell selected by the terminal to allocate and control physical resources. Furthermore, the coordinated cell can statically allocate and control physical resources, and can also dynamically allocate and control physical resources according to service requirements and / or loads. In this embodiment, the control physical resources negotiated by the coordinated cell may...

[0059] Example 2: Independent allocation

[0060] CoMP11 does not specifically select a certain group or several groups of resources. However, the cooperating cells in CoMP11 coordinate with each other when allocating resources for UEs in CoMP mode. For example: resource group 1 includes resource a and resource b, resource group 2 includes resource c and resource d, Cell1 can only allocate resource a and resource b, and Cell2 can only allocate resource c and resource d. Cell1 allocates resource a in resource group 1 to UE1. At the same time, Cell1 can inform Cell2 of the use of resource a. When Cell2 allocates resources to UE2, Cell2 can choose from resource c and resource d. The interaction with resource a is small. H. That is, Cell1 and Cell2 can coordinate with each other when allocating resources. The resources allocated to UE3 and UE1, UE4 and UE2 may be the same or different;

Abstract

A method, an apparatus and a system for transmitting uplink information are provided. The method includes: obtaining an uplink physical resource and an uplink mapping rule corresponding to a Physical Uplink Control Channel, PUCCH, and / or a Physical Random Access Channel, PRACH, and / or a Reference Symbol, RS, which are negotiated by coordinated cells; and using the uplink physical resource to transmit uplink control information and / or random access information and / or the RS according to the uplink mapping rule. Multiple coordinated cells collaborate to allocate the uplink physical resource corresponding to the PUCCH and / or the PRACH and / or the RS, and use the uplink physical resource to transmit the uplink control information and / or the random access information and / or the RS according to the uplink mapping rule. In this way, the uplink control information, the random access information, and the RS are transmitted by the coordinated cells collaboratively; the effective coverage of the coordinated cells is improved; and the interference between the coordinated cells is reduced effectively.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a transmission method, device and system for uplink information. Background technique [0002] In a wireless communication system, in order to improve the downlink transmission performance of cell edge users, downlink coordinated multi-point transmission in the Coordinated Multi-Point transmission (CoMP for short) technology can be used, that is, multiple cells jointly transmit data to the same terminal. The signal is transmitted so as to enhance the signal to interference-and-noise ratio (SINR) of the signal received by the terminal or improve the throughput of system transmission. Among them, multiple cells that use the CoMP technology to transmit signals to the same terminal are called coordinated cells, and the coordinated cells can be divided into an anchor cell (Anchor Cell) and a serving cell (Serving Cell). For the uplink data information, the shared physic...
